[0002] With the development of new energy technologies, batteries are being used more and more widely. Batteries, with their high energy density, high safety, long lifespan, and environmental friendliness, are widely used in passenger cars, commercial vehicles, electric bicycles, heavy trucks, energy storage facilities, battery swapping stations, engineering manufacturing, and intelligent devices. They are also driving technological development and research in communication, medical devices, and energy development. However, dust generated during battery production can seriously affect battery quality and the stability of production equipment. Therefore, dust removal devices are commonly used in related technologies to remove dust generated by production equipment, ensuring battery production safety and maintaining stable equipment operation. However, existing dust removal devices are prone to explosions and fires during use, posing significant safety hazards. Summary of the Invention

[0003] This application provides a dust removal device, a dust removal equipment, and a control method for the dust removal device and the dust removal equipment, which can effectively improve the safety of the dust removal device.

[0004] In a first aspect, embodiments of this application provide a dust removal device, including a first processing chamber and an air blowing mechanism; the first processing chamber is provided with a first filter element inside, the first filter element divides the internal space of the first processing chamber into an air inlet space and an air outlet space, the first filter element is configured to filter dust in the gas entering the air outlet space from the air inlet space, the first processing chamber is provided with an exhaust section, the exhaust section is connected to the exhaust space, the exhaust section is configured to discharge the gas in the exhaust space; the air blowing mechanism is configured to blow air into the exhaust section to clean at least a portion of the dust on the first filter element.

[0005] In the above technical solution, a first filter element is provided in the first processing chamber, and the first filter element divides the internal space of the first processing chamber into an air intake space and an exhaust space, so that the gas can enter the air intake space and the exhaust space of the first processing chamber in sequence and then be discharged through the exhaust section, so that the dust in the gas can be filtered by the first filter element, thereby achieving the effect of dust removal. The dust removal device is equipped with an air blowing mechanism that blows air into the exhaust section. This allows the air backflow from the air blowing mechanism to sequentially enter the exhaust space and intake space of the first processing chamber. This backflow removes the dust adsorbed on the first filter element, achieving reverse air blowing cleaning of the first filter element. This helps alleviate excessive dust accumulation on the first filter element, thus improving its subsequent performance and lifespan, and extending the overall lifespan of the dust removal device. Furthermore, it mitigates the risk of excessive dust clogging the first filter element, preventing air from entering the exhaust space and exiting through the exhaust section. This reduces the risk of increased internal pressure in the first processing chamber due to gas accumulation in the intake space. It also mitigates the risk of electrostatic combustion caused by dust accumulation on the first filter element, thus reducing the likelihood of the first processing chamber bursting or exploding, and improving the safety of the dust removal device.

[0006] In some embodiments, the first processing chamber is further provided with a first detection element, which is used to detect state parameters in the air intake space, and the blowing mechanism responds to the first detection element.

[0007] In the above technical solution, the first processing chamber is equipped with a first detection element. The first detection element can detect the state parameters in the air intake space of the first processing chamber. By feeding back the state parameters in the air intake space, the dust accumulation on the first filter element can be obtained. This allows the blowing mechanism to blow air into the exhaust section after responding to the first detection element, thereby achieving reverse blowing cleaning of the first filter element. The dust removal device with this structure can monitor the usage of the first filter element in real time and realize the automatic control of the blowing mechanism. While reducing manual intervention, it can perform reverse blowing cleaning of the first filter element according to the actual usage, thereby effectively improving the safety of the dust removal device.

[0008] In some embodiments, the blowing mechanism includes a gas storage component, a blowing pipe, and a first valve; the gas storage component is used to store gas; the blowing pipe is connected to the gas storage component and is correspondingly disposed to the exhaust section, the blowing pipe being configured to blow gas into the exhaust section; the first valve is correspondingly disposed to the blowing pipe, the first valve being used to open or close the blowing pipe, and the first valve responding to the first detection component.

[0009] In the above technical solution, the blowing mechanism is provided with an air storage component and an air blowing pipe. The air blowing pipe is connected to the air storage component, so that the air blowing pipe can discharge the air stored in the air storage component and blow air into the interior of the exhaust section. By providing a first valve on the air blowing pipe for opening or closing the air blowing pipe, and the first valve responding to a first detection component, the first valve can open or close the air blowing pipe according to the detection result of the first detection component, so that the blowing mechanism can respond to the first detection component. The structure is simple and easy to implement.

[0010] In some embodiments, the dust removal device further includes an air inlet pipe; the air inlet pipe is connected to the air intake space and is configured to input gas into the air intake space; wherein, a second valve is provided on the air inlet pipe, the second valve is configured to open or close the air inlet pipe, and the second valve is responsive to the first detection element.

[0011] In the above technical solution, the dust removal device is also provided with an air inlet pipe that communicates with the air inlet space, and a second valve is provided on the air inlet pipe. The second valve can respond to the first detection, so that the second valve can close the air inlet pipe when the blowing mechanism blows air in the opposite direction to the exhaust section. On the one hand, it can prevent gas from continuing to enter the air inlet space and affecting the cleaning effect of the first filter element. On the other hand, it can alleviate the phenomenon of dust flowing in the opposite direction in the air inlet pipe due to the blowing mechanism blowing air in the opposite direction, so as to reduce the risk of dust backflow.

[0012] In some embodiments, the first filter element is a hollow structure, the air intake space is located outside the first filter element, and the exhaust space is located inside the first filter element.

[0013] In the above technical solution, by setting the first filter element as a hollow structure, the space inside the first filter element is the exhaust space, and the space outside the first filter element is the intake space. The first filter element with this structure can, on the one hand, increase the filtration area of ​​the gas from the intake space into the exhaust space, thereby improving the filtration effect of the dust removal device. On the other hand, when the blowing mechanism back-blowing gas into the exhaust space through the exhaust section, the gas can overflow from the exhaust space to the periphery of the first filter element into the intake space, thereby improving the cleaning effect of the first filter element when the blowing mechanism back-blowing gas into the exhaust space.

[0014] In some embodiments, the first processing chamber is provided with a plurality of the first filter elements, and the exhaust space inside each of the first filter elements is in communication with an exhaust section.

[0015] In the above technical solution, by setting multiple first filter elements in the first processing chamber, and each exhaust section is connected to the exhaust space of a first filter element, that is, each first filter element is provided with an exhaust section, it is beneficial to improve the efficiency of the dust removal device in removing dust from the gas.

[0016] In some embodiments, the exhaust portion is a Venturi nozzle disposed on the first processing chamber.

[0017] In the above technical solution, by setting the exhaust section as a Venturi nozzle connected to the first processing chamber, the exhaust section with this structure is easy to install and has low pressure loss and good stability when the gas is discharged from the exhaust space through the exhaust section. On the other hand, when the blowing mechanism blows the gas back into the exhaust space through the exhaust section, the gas has good flow and a large diffusion range, which is conducive to improving the cleaning effect of the gas blown back by the blowing mechanism on the first filter element.

[0018] In some embodiments, the dust removal device further includes a second processing chamber, the exhaust section connects the exhaust space and the internal space of the second processing chamber, and the air blowing mechanism is disposed in the second processing chamber.

[0019] In the above technical solution, the dust removal device is also provided with a second processing chamber. The second processing chamber is connected to the exhaust space of the first processing chamber through the exhaust section, so that the gas in the exhaust space can enter the second processing chamber after passing through the exhaust section. By setting the blowing mechanism in the second processing chamber, it is convenient for the blowing mechanism to blow air into the interior of the exhaust section to clean the first filter element by reverse blowing. The second processing chamber can also provide a certain degree of protection for the blowing mechanism to reduce the risk of damage to the blowing mechanism.

[0020] In some embodiments, the dust removal device further includes an air extraction mechanism; the air extraction mechanism is in communication with the internal space of the second processing chamber, and the air extraction mechanism is configured to extract gas from the second processing chamber.

[0021] In the above technical solution, the dust removal device is also equipped with an air extraction mechanism, which is connected to the internal space of the second processing chamber. The air extraction mechanism can extract the gas in the second processing chamber to improve the flow of the gas through the air inlet space, the exhaust space, the exhaust section and the second processing chamber in sequence, which is beneficial to improving the dust removal efficiency of the dust removal device.

[0022] In some embodiments, a second filter element is provided in the second processing chamber, the second filter element being configured to filter dust in the gas entering the exhaust mechanism from the internal space of the second processing chamber.

[0023] In the above technical solution, by setting a second filter element in the second processing chamber, the second filter element can filter the dust in the gas entering the extraction mechanism from the second processing chamber, thereby achieving further filtration of the gas and realizing a two-stage filtration structure for the dust removal device, which is conducive to improving the dust removal effect of the dust removal device.

[0024] In some embodiments, the dust removal device further includes an installation chamber, and the air extraction mechanism is disposed within the installation chamber.

[0025] In the above technical solution, the dust removal device is also equipped with an installation chamber, and the air extraction mechanism is installed inside the installation chamber, so that the installation chamber can play a certain role in protecting the air extraction mechanism and alleviate the risk of damage to the air extraction mechanism.

[0026] In some embodiments, a mounting base is provided inside the mounting chamber, the air extraction mechanism is mounted on the mounting base, and a shock-absorbing component is provided between the air extraction mechanism and the mounting base.

[0027] In the above technical solution, by setting a mounting base for installing the air extraction mechanism in the installation chamber, and by setting a shock-absorbing component between the mounting base and the air extraction mechanism, the vibration generated by the air extraction mechanism during use can be mitigated, thereby reducing the impact and damage to the dust removal device caused by the vibration of the air extraction mechanism, which is conducive to improving the service life of the dust removal device.

[0028] In some embodiments, the dust removal device further includes a silencing mechanism, which is connected to the exhaust port of the extraction mechanism.

[0029] In the above technical solution, the dust removal device is also equipped with a silencing mechanism, which is connected to the exhaust port of the extraction mechanism, so that the silencing mechanism can play a role in silencing the gas discharged by the extraction mechanism, thereby reducing the adverse effects of noise on production.

[0030] In some embodiments, the first processing chamber is further provided with a first explosion relief mechanism, which is configured to release the internal pressure of the first processing chamber.

[0031] In the above technical solution, the first processing chamber is also equipped with a first explosion relief mechanism. When a fire or explosion occurs inside the first processing chamber, the internal pressure of the first processing chamber can be released to improve the safety of the dust removal device and reduce damage to the dust removal device.

[0032] In some embodiments, the dust removal device further includes a flame arrester and an air inlet pipe; the flame arrester is disposed in the first processing chamber; the air inlet pipe is connected to the air intake space through the flame arrester, and the air inlet pipe is configured to input gas into the air intake space.

[0033] In the above technical solution, the dust removal device is also equipped with an air inlet pipe that communicates with the air inlet space. The air inlet pipe is connected to the air inlet space of the first processing chamber through a flame arrester installed on the first processing chamber. In this way, when a fire occurs in the air inlet pipe, it can effectively prevent the flame from entering the air inlet space and further causing the first processing chamber to explode, thereby improving the safety of the dust removal device.

[0034] Secondly, embodiments of this application also provide a dust removal device, including a powder sprayer and the aforementioned dust removal device; the powder sprayer is connected to the first processing chamber, and the powder sprayer is configured to provide inerting powder into the air intake space.

[0035] In the above technical solution, by connecting the powder sprayer to the air intake space of the first processing chamber, the powder sprayer can provide inert powder into the air intake space, so that the dust in the air intake space can be mixed with the inert powder, thereby reducing the concentration of flammable and explosive dust in the gas, which is beneficial to suppressing dust spontaneous combustion, thereby reducing the risk of dust fire and explosion in the air intake space, and improving the safety of dust removal equipment.

[0036] In some embodiments, the dust removal equipment further includes a first detection unit and a controller; the first detection unit is disposed inside the powder sprayer and is configured to detect the weight of the inerting powder inside the powder sprayer; the controller is electrically connected to the powder sprayer and the first detection unit, and is used to adjust the powder output of the powder sprayer according to the detection result of the first detection unit.

[0037] In the above technical solution, the dust removal equipment is also equipped with a first detection unit and a controller. By setting the first detection unit inside the powder sprayer, the first detection unit can detect the weight of the inerting powder inside the powder sprayer. This allows the controller to adjust the amount of inerting powder supplied by the powder sprayer to the air intake space based on the weight change detected by the first detection unit. On the one hand, this can alleviate the phenomenon that the inerting powder is not effective in suppressing dust ignition and spontaneous combustion in the first treatment chamber due to insufficient inerting powder supply. On the other hand, it can alleviate the phenomenon that excessive inerting powder supply leads to waste and excessive filtration pressure of the first filter element.

[0038] Thirdly, this application also provides a control method for a dust removal device, applicable to the aforementioned dust removal device. The control method for the dust removal device includes: acquiring state parameters within the air intake space, the state parameters including air pressure or dust concentration; if the state parameters within the air intake space are greater than or equal to a threshold, controlling the blowing mechanism to operate for a first preset time to blow air into the exhaust section.

[0039] In the above technical solution, state parameters representing air pressure or dust concentration in the air intake space of the first processing chamber are first obtained to provide feedback on the dust accumulation on the first filter element. When the state parameters in the air intake space reach a threshold, the blowing mechanism can be controlled to run for a first preset time to blow air back into the air intake space through the exhaust section, thereby achieving reverse blowing cleaning of the first filter element. This realizes automatic control of the blowing mechanism, reduces manual intervention, and enables reverse blowing cleaning of the first filter element according to actual usage conditions, thus effectively improving the safety of the dust removal device.

[0040] In some embodiments, the dust removal device further includes an air extraction mechanism connected to the exhaust section; after controlling the air blowing mechanism to run for a first preset time to blow air into the exhaust section if the state parameter in the air intake space is greater than or equal to a threshold, the control method of the dust removal device further includes: after the air blowing mechanism runs for the first preset time, acquiring the state parameter in the air intake space again; if the state parameter in the air intake space is not lower than the threshold, controlling the air extraction mechanism to stop running.

[0041] In the above technical solution, after the blowing mechanism blows air into the air intake space through the exhaust section for a first preset time, the state parameters of the air intake space of the first processing chamber are obtained again. If the state parameters representing the air pressure or dust concentration in the air intake space still have not dropped below the threshold, the air extraction mechanism of the dust removal device is stopped, which can alleviate the safety hazards caused by the further increase of air pressure in the air intake space, and thus help improve the safety of the dust removal device.

[0042] In some embodiments, the dust removal device further includes an air extraction mechanism connected to the exhaust section; after acquiring the state parameters in the air intake space, the control method of the dust removal device further includes: if the state parameters in the air intake space remain unchanged for a second preset time period, controlling the air extraction mechanism to stop operating.

[0043] In the above technical solution, after obtaining the state parameters representing the air pressure or dust concentration in the air intake space, it is also possible to determine whether the state parameters remain unchanged within a second preset time period based on the state parameters in the air intake space. If the state parameters remain unchanged, the dust removal device may have component damage. Therefore, by stopping the air extraction mechanism, the further safety hazards of the dust removal device can be alleviated.

[0044] Fourthly, this application also provides a control method for a dust removal device, applicable to the aforementioned dust removal device. The control method includes: obtaining the amount of powder output from the powder sprayer within a third preset time period; and adjusting the amount of powder output from the powder sprayer if the amount of powder output from the powder sprayer is not within a preset range.

[0045] In the above technical solution, by obtaining the amount of powder output from the powder sprayer within a third preset time period, the amount of inerting powder supplied by the powder sprayer to the air intake space of the first processing chamber is fed back. This allows the amount of inerting powder supplied by the powder sprayer to the air intake space to be adjusted when the powder output of the powder sprayer is not within the preset range. On the one hand, this can alleviate the phenomenon that the inerting powder is not effective in suppressing dust ignition and spontaneous combustion in the first processing chamber due to insufficient inerting powder supply. On the other hand, it can alleviate the phenomenon that excessive inerting powder supply leads to waste and excessive filtration pressure of the first filter element.

[0046] In some embodiments, the dust removal device further includes an air extraction mechanism connected to the exhaust section; after adjusting the powder output of the powder sprayer if the powder output is not within a preset range, the control method of the dust removal device further includes: acquiring the powder output of the powder sprayer again within a third preset time period; if the powder output of the powder sprayer is not within a preset range, controlling the air extraction mechanism to stop operating.

[0047] In the above technical solution, after adjusting the powder output of the powder sprayer, the powder output of the powder sprayer is obtained again within a third preset time period. If the powder output of the powder sprayer is still not within the preset range, the exhaust mechanism of the dust removal device is stopped, which can alleviate the safety hazards caused by too much or too little inerting powder, and thus help improve the safety of the dust removal equipment.

[0048] In some embodiments, the amount of powder dispensed by the powder sprayer during a third preset time period is obtained based on the weight change of the inerting powder in the powder sprayer during a third preset time period.

[0049] In the above technical solution, the amount of powder output from the powder sprayer within the third preset time period is calculated and obtained by acquiring the weight change of the inerting powder in the powder sprayer within the third preset time period. This is easy to implement and operate, and helps to reduce programming costs. Attached Figure Description

[0066] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0067] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0068] In this application, "multiple" means two or more (including two).

[0069] The battery mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity.

[0070] In some embodiments, the battery can be a battery module, and when there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0071] In some embodiments, the battery can be a battery pack, which includes a housing and individual battery cells, with the individual battery cells or battery modules housed within the housing.

[0072] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0073] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

Prismatic battery cells include, but are not limited to, square battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries.

[0076] During battery production, equipment often generates dust, which can severely impact battery quality and the stability of the equipment. Furthermore, dust concentrations exceeding a certain level can easily lead to fires and explosions. With the increasing demand in the new energy market and the resulting battery shortage, production equipment is adding more workstations to increase capacity, further increasing the amount of dust generated during battery production.

[0077] In battery manufacturing technology, dust removal devices are typically used to remove dust generated during production, reducing the dust content in the equipment and ensuring safe battery production and stable equipment operation. However, because the dust generated during battery production is highly flammable and explosive, when the dust accumulates to a certain concentration in the dust removal device, it can easily cause fires and explosions, potentially damaging the device itself. This poses a significant safety hazard during the use of the dust removal device and is detrimental to battery production.

[0078] Based on the above considerations, and to address the issue of low safety during the use of dust removal devices, this application provides a dust removal device comprising a first processing chamber and an air blowing mechanism. A first filter element is disposed inside the first processing chamber, dividing the internal space of the first processing chamber into an inlet space and an exhaust space. The first filter element is configured to filter dust in the gas entering the exhaust space from the inlet space. An exhaust section is disposed on the first processing chamber, communicating with the exhaust space, and is configured to discharge gas from the exhaust space. The air blowing mechanism is configured to blow air into the exhaust section to clean at least a portion of the dust on the first filter element.

[0079] In this dust removal device with this structure, a first filter element is installed in the first processing chamber, and the first filter element divides the internal space of the first processing chamber into an air inlet space and an air outlet space, so that the gas can enter the air inlet space and the air outlet space of the first processing chamber in sequence and then be discharged through the exhaust section, so that the dust in the gas can be filtered by the first filter element, thereby achieving the dust removal effect. The dust removal device is equipped with an air blowing mechanism that blows air into the exhaust section. This allows the air backflow from the air blowing mechanism to sequentially enter the exhaust space and intake space of the first processing chamber. This backflow removes the dust adsorbed on the first filter element, achieving reverse air blowing cleaning of the first filter element. This helps alleviate excessive dust accumulation on the first filter element, thus improving its subsequent performance and lifespan, and extending the overall lifespan of the dust removal device. Furthermore, it mitigates the risk of excessive dust clogging the first filter element, preventing air from entering the exhaust space and exiting through the exhaust section. This reduces the risk of increased internal pressure in the first processing chamber due to gas accumulation in the intake space. It also mitigates the risk of electrostatic combustion caused by dust accumulation on the first filter element, thus reducing the likelihood of the first processing chamber bursting or exploding, and improving the safety of the dust removal device.

[0080] This application provides a dust removal device that can improve the risks of fire and explosion that may occur during the use of dust removal devices, which can cause the dust removal devices to be easily damaged and pose significant safety hazards. This can ensure the production safety of batteries and maintain the stable operation of the equipment. The specific structure of the dust removal device is described in detail below with reference to the accompanying drawings.

[0081] According to some embodiments of this application, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a dust removal device 1000 provided in some embodiments of this application. The dust removal device 1000 includes a dust removal unit 100 and a powder sprayer 200. The dust removal unit 100 has an inlet pipe 10 for communicating with the production equipment 2000. The inlet pipe 10 is configured to transport the gas generated by the production equipment 2000 to the dust removal unit 100, and the dust removal unit 100 is configured to filter dust in the gas. The powder sprayer 200 has a conveying pipe 210 communicating with the inlet pipe 10. The powder sprayer 200 is configured to provide inert powder into the inlet pipe 10. The specific structure of the powder sprayer 200 can be found in related technologies and will not be described in detail here.

[0082] The powder sprayer 200 provides inert powder into the air intake pipe 10, so that the inert powder can suppress the spontaneous combustion of dust after being sprayed into the air intake pipe 10. The inert powder provided by the powder sprayer 200 can be of various types, such as sodium bicarbonate powder or calcium carbonate powder.

[0083] In some embodiments, see Figure 1As shown, the intake pipe 10 may also be sequentially equipped with a first air valve 11, a make-up air pipe 12, a second explosion relief mechanism 13, a barrier valve 14, and a speedometer 15. The first air valve 11 is located at the end of the intake pipe 10 closest to the production equipment 2000, and is configured to regulate the amount of gas entering the intake pipe 10 from the production equipment 2000. The make-up air pipe 12 is connected to the intake pipe 10, and a second air valve 16 is also installed on the make-up air pipe 12. The second air valve 16 is configured to regulate the amount of gas entering the intake pipe 10 from the make-up air pipe 12 to alleviate the phenomenon of insufficient gas flow velocity within the intake pipe 10. The second explosion relief mechanism 13 is configured to release the internal pressure of the intake pipe 10. The barrier valve 14 is used to open or close the intake pipe 10 to isolate the intake pipe 10 in the event of a fire or explosion within the production equipment 2000 or the intake pipe 10. The speed meter 15 is located between the connection point of the barrier valve 14 and the delivery pipe 210 of the powder injector 200 and the air intake pipe 10. The speed meter 15 is configured to detect the flow rate of the gas in the air intake pipe 10. The intake volume of the mixed gas in the intake pipe 10 can be adjusted by the first air valve 11, the make-up air pipe 12, and the second air valve 16 on the make-up air pipe 12. Furthermore, by installing a second explosion relief mechanism 13 on the intake pipe 10 and a barrier valve 14 between the second explosion relief mechanism 13 and the speedometer 15, the barrier valve 14 can block other components of the dust removal device 100 and the powder sprayer 200 in the event of a fire or explosion of the mixed gas in the production equipment 2000 or the intake pipe 10. This reduces the impact of the shock wave generated by the explosion on the dust removal device 100 and the powder sprayer 200, mitigating the risk of damage to them. The second explosion relief mechanism 13 can also vent the shock wave generated by an explosion occurring within the intake pipe 10, further reducing the risk of damage to the intake pipe 10 and thus improving the service life and reliability of the dust removal device 100. The speedometer 15 can detect the gas velocity inside the intake pipe 10. When the speedometer 15 detects that the gas velocity inside the intake pipe 10 is lower than a preset value, the speedometer 15 can issue an alarm to alleviate the accumulation of dust inside the intake pipe 10. For example, the preset value can be 23 m / s.

[0084] For example, the structures of the first air valve 11 and the second air valve 16 can be various, such as butterfly regulating valve, single-leaf regulating valve, slide gate valve, parallel multi-leaf regulating valve, split multi-leaf regulating valve, diamond multi-leaf regulating valve, compound multi-leaf regulating valve or three-way regulating valve, etc.

[0085] For example, the structure of the second explosion relief mechanism 13 can be various. For instance, the second explosion relief mechanism 13 can be a flameless explosion relief device or explosion relief disc installed on the air intake pipe 10.

[0086] For example, the structure of the barrier valve 14 can be various, such as a mechanical explosion-proof valve or an electromagnetic explosion-proof valve.

[0087] For example, the structure of the speedometer 15 can also be various, such as a cup anemometer or a wing anemometer.

[0088] According to some embodiments of this application, refer to Figure 1 Please refer to further details. Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a schematic diagram of the structure of the dust removal device 100 provided in some embodiments of this application. Figure 3 This is a left view of a dust removal device 100 provided in some embodiments of this application. Figure 4 This is a cross-sectional view of a dust removal device 100 provided in some embodiments of this application. Embodiments of this application provide a dust removal device 100, which includes a first processing chamber 20 and an air blowing mechanism 30. A first filter element 40 is disposed inside the first processing chamber 20, dividing the internal space of the first processing chamber 20 into an air inlet space 21 and an exhaust space 22. The first filter element 40 is configured to filter dust in the gas entering the exhaust space 22 from the air inlet space 21. An exhaust section 23 is disposed on the first processing chamber 20, communicating with the exhaust space 22, and is configured to discharge gas from the exhaust space 22. The air blowing mechanism 30 is configured to blow air into the exhaust section 23 to clean at least a portion of the dust on the first filter element 40.

[0089] The first processing chamber 20 is connected to the air inlet pipe 10, and the air inlet pipe 10 is connected to the air inlet space 21 of the first processing chamber 20, so that the air inlet pipe 10 can transport the dust generated by the production equipment 2000 to the air inlet space 21 of the first processing chamber 20.

[0090] The first filter element 40 divides the internal space of the first processing chamber 20 into an intake space 21 and an exhaust space 22. The structure of the first filter element 40 can be varied. For example, the first filter element 40 can be a plate-like structure, or it can be a hollow structure. That is, the first filter element 40 is disposed inside the first processing chamber 20, and the space inside the first processing chamber 20 containing the first filter element 40 is the exhaust space 22, while the space outside the first processing chamber 20 containing the first filter element 40 is the intake space 21. Correspondingly, when the first filter element 40 is a hollow structure, there can be one or more first filter elements 40 disposed inside the first processing chamber 20, and each first filter element 40 is provided with an exhaust section 23.

[0091] For example, the first filter element 40 is a cylindrical hollow structure, and four first filter elements 40 are provided in the first processing chamber 20 to divide the internal space of the first processing chamber 20 into an air intake space 21 and four exhaust spaces 22. Correspondingly, four exhaust parts 23 are provided on the first processing chamber 20, and each exhaust part 23 is connected to an exhaust space 22.

[0092] The first filter element 40 serves to filter dust from the gas entering the exhaust space 22 from the intake space 21. The material of the first filter element 40 can be various, such as wood pulp fiber or glass fiber. In some embodiments, the surface of the first filter element 40 facing the intake space 21 is covered with a nanofiber layer, which helps to improve the filtration effect. Optionally, the first filter element 40 can also be treated by a carburizing process to give the first filter element 40 flame-retardant and anti-static functions.

[0093] An exhaust section 23 is provided on the first processing chamber 20, and the exhaust section 23 communicates with the exhaust space 22. The exhaust section 23 serves to discharge the gas in the exhaust space 22 of the first processing chamber 20. The structure of the exhaust section 23 can be various; for example, the exhaust section 23 can be an exhaust hole provided in the first processing chamber 20, or an exhaust nozzle or exhaust valve connected to the first processing chamber 20, etc. For example, in Figure 4 In this process, the exhaust section 23 is an exhaust nozzle provided on the first processing chamber 20, and part of the exhaust nozzle extends into the exhaust space 22 so that the exhaust nozzle communicates with the exhaust space 22.

[0094] The blowing mechanism 30 is configured to blow air into the exhaust section 23 to clean at least part of the dust on the first filter element 40. In other words, the blowing mechanism 30 can backflush gas into the exhaust space 22 through the exhaust section 23, so that the backflush gas in the first processing chamber 20 presents a flow path from the exhaust space 22 through the first filter element 40 and into the intake space 21, so as to blow away part or all of the dust attached to the first filter element 40, thereby achieving the function of cleaning the first filter element 40.

[0095] The first processing chamber 20 is equipped with a first filter element 40, which divides the internal space of the first processing chamber 20 into an air inlet space 21 and an exhaust space 22. Gas can sequentially enter the air inlet space 21 and the exhaust space 22 of the first processing chamber 20 and then be discharged through the exhaust section 23. The first filter element 40 filters dust from the gas, thus achieving a dust removal effect. The dust removal device 100 is equipped with a blowing mechanism 30, which blows air into the exhaust section 23. This allows the air blown back into the exhaust space 22 and the air inlet space 21 of the first processing chamber 20, thus blowing away the dust filtered and adsorbed on the first filter element 40. This reverse blowing cleaning of the first filter element 40 helps to alleviate excessive dust accumulation on it, thereby cleaning the first filter element 40 and improving its performance. The subsequent use effect and service life of the filter element 40 are conducive to improving the service life of the dust removal device 100. On the other hand, it can alleviate the phenomenon that gas cannot enter the exhaust space 22 and be discharged through the exhaust section 23 due to excessive dust clogging the first filter element 40. This reduces the risk of increased internal air pressure in the first processing chamber 20 due to gas accumulation in the intake space 21. It can also alleviate the phenomenon of static electricity spontaneous combustion caused by dust accumulation on the first filter element 40. This helps to alleviate the phenomenon of explosion or bursting of the first processing chamber 20 of the dust removal device 100, thereby improving the safety of the dust removal device 100.

[0096] According to some embodiments of this application, see Figure 4 As shown, the first processing chamber 20 is also provided with a first detection element 27, which is used to detect the state parameters in the air intake space 21, and the air blowing mechanism 30 responds to the first detection element 27.

[0097] The first detection element 27 is used to detect the state parameters in the air intake space 21. The first detection element 27 can be used to detect the air pressure in the air intake space 21 of the first processing chamber 20, or it can be used to detect the dust concentration in the air intake space 21 of the first processing chamber 20.

[0098] In this embodiment, the first detection element 27 is used to detect the air pressure in the air intake space 21 of the first processing chamber 20, so as to issue an alarm when the air pressure in the air intake space 21 of the first processing chamber 20 reaches a threshold. For example, the structure of the first detection element 27 can be various, such as a piezoresistive pressure sensor or a piezoelectric pressure sensor.

[0099] The blowing mechanism 30 responds to the first detection element 27, that is, when the first detection element 27 detects that the state parameter of the air intake space 21 of the first processing chamber 20 reaches a threshold, for example, when the air pressure reaches a threshold, the blowing mechanism 30 can respond to the detection result of the first detection element 27 and start to backflush the gas in the exhaust space 22.

[0100] The first processing chamber 20 is equipped with a first detection element 27, which can detect the state parameters within the air intake space 21 of the first processing chamber 20. The feedback of the state parameters within the air intake space 21 can reveal the dust accumulation on the first filter element 40. This allows the blowing mechanism 30 to blow air into the exhaust section 23 in response to the first detection element 27, achieving reverse air blowing cleaning of the first filter element 40. The dust removal device 100 with this structure can monitor the usage of the first filter element 40 in real time and achieve automatic control of the blowing mechanism 30. While reducing manual intervention, it can perform reverse air blowing cleaning of the first filter element 40 according to the actual usage, thereby effectively improving the safety of the dust removal device 100.

[0101] According to some embodiments of this application, see Figure 4 As shown, the air blowing mechanism 30 includes an air storage component 31, an air blowing pipe 32, and a first valve 33. The air storage component 31 is used to store gas. The air blowing pipe 32 communicates with the air storage component 31 and is correspondingly arranged with the exhaust section 23, and is configured to blow air into the exhaust section 23. The first valve 33 is correspondingly arranged with the air blowing pipe 32, and is used to open or close the air blowing pipe 32, and is responsive to the first detection element 27.

[0102] The gas storage component 31 stores gas so that it can be backflushed into the exhaust space 22. The structure of the gas storage component 31 can be various, such as a gas tank or a gas bladder.

[0103] The air blowing pipe 32 is connected to the gas storage unit 31, and the air blowing pipe 32 is correspondingly arranged with the exhaust section 23. That is, the air blowing pipe 32 is used to export the gas in the gas storage unit 31 and blow air into the exhaust section 23. Each air blowing pipe 32 backflushs gas into one exhaust section 23. For example, in Figure 4 In the first filter element 40, there are four, and correspondingly, there are four exhaust parts 23. Similarly, the blowing mechanism 30 is provided with four blowing pipes 32. All four blowing pipes 32 are connected to the air storage element 31. Each blowing pipe 32 blows air into an exhaust space 22 through an exhaust part 23.

[0104] The first valve 33 is correspondingly provided with the air blowing pipe 32. The first valve 33 is used to open or close the air blowing pipe 32. That is, each air blowing pipe 32 is provided with a corresponding first valve 33, and the first valve 33 plays the role of opening or closing the air blowing pipe 32, thereby realizing the start or stop of the air blowing mechanism 30. For example, the structure of the first valve 33 can be various, such as a direct-acting solenoid valve, a step-by-step direct-acting solenoid valve, or a pilot-operated solenoid valve.

[0105] The first valve 33 responds to the first detection element 27. That is, when the first detection element 27 detects that the state parameter of the air intake space 21 of the first processing chamber 20 reaches a threshold, for example, when the air pressure reaches a threshold, the first valve 33 can respond to the detection result of the first detection element 27 and open the air blowing pipe 32 so that the air blowing pipe 32 can backflush gas into the exhaust space 22.

[0106] It should be noted that in other embodiments, the blowing mechanism 30 may also be a fan or the like installed on the first processing chamber 20.

[0107] The air blowing mechanism 30 is provided with an air storage component 31 and an air blowing pipe 32. The air blowing pipe 32 is connected to the air storage component 31, so that the air blowing pipe 32 can discharge the air stored in the air storage component 31 and blow air into the exhaust section 23. By providing a first valve 33 on the air blowing pipe 32 for opening or closing the air blowing pipe 32, and the first valve 33 responding to the first detection component 27, the first valve 33 can open or close the air blowing pipe 32 according to the detection result of the first detection component 27, so that the air blowing mechanism 30 can respond to the first detection component 27. The structure is simple and easy to implement.

[0108] According to some embodiments of this application, see Figure 1 , Figure 2 and Figure 3 As shown, the dust removal device 100 also includes an air inlet pipe 10, which is connected to the air inlet space 21. The air inlet pipe 10 is configured to input gas into the air inlet space 21. A second valve 17 is provided on the air inlet pipe 10, which is configured to open or close the air inlet pipe 10. The second valve 17 is responsive to the first detection element 27.

[0109] Among them, see Figure 1 As shown, the second valve 17 is located between the connection point of the delivery pipe 210 of the speedometer 15 and the powder sprayer 200 and the air inlet pipe 10.

[0110] The second valve 17 responds to the first detection element 27. That is, when the first detection element 27 detects that the state parameter of the air intake space 21 of the first processing chamber 20 reaches a threshold, such as when the air pressure reaches a threshold, the second valve 17 can respond to the detection result of the first detection element 27 and close the air intake pipe 10 to prevent dust from further entering the air intake space 21 of the first processing chamber 20.

[0111] For example, the structure of the second valve 17 can be various, such as a direct-acting solenoid valve, a step-by-step direct-acting solenoid valve, or a pilot-operated solenoid valve.

[0112] The dust removal device 100 is also provided with an air inlet pipe 10 that communicates with the air inlet space 21, and a second valve 17 is provided on the air inlet pipe 10. The second valve 17 can respond to the first detection, so that the second valve 17 can close the air inlet pipe 10 when the blowing mechanism 30 blows air in the opposite direction to the exhaust section 23. On the one hand, it can prevent gas from continuing to enter the air inlet space 21 and affecting the cleaning effect of the first filter element 40. On the other hand, it can alleviate the phenomenon of dust flowing in the reverse direction in the air inlet pipe 10 due to the reverse blowing of the blowing mechanism 30, so as to reduce the risk of dust backflow.

[0113] In some embodiments, see Figure 2 and Figure 4 As shown, a hopper 24 is connected to the bottom of the first processing chamber 20, and a material barrel 25 is connected to the bottom of the hopper 24. The material barrel 25 is connected to the air intake space 21 of the first processing chamber 20 through the hopper 24. The material barrel 25 is used to contain the dust filtered by the first filter element 40.

[0114] The material bucket 25 is detachably connected to the hopper 24 to facilitate the cleaning of dust inside the material bucket 25. The detachable connection structure between the material bucket 25 and the hopper 24 can be of various types, such as bolt connection or snap connection.

[0115] Optionally, a third valve 241 is also provided at the bottom of the hopper 24. The third valve 241 is configured to open or close the hopper 24 to isolate or connect the hopper 24 and the material barrel 25, so that the hopper 24 can be closed after the material barrel 25 is disassembled to alleviate the phenomenon of dust falling.

[0116] For example, the structure of the third valve 241 can be various, such as a fixed ball valve, a floating ball valve, or a high-performance butterfly valve.

[0117] The hopper 24 may also be equipped with a second detection element 242, which is configured to detect whether the third valve 241 is closed in place. For example, the second detection element 242 may be an eddy current proximity switch or a capacitive proximity switch.

[0118] Optionally, a third detection element 26 may be provided between the hopper 24 and the bucket 25. The third detection element 26 is configured to detect whether the hopper 24 and the bucket 25 are connected in place. For example, the third detection element 26 may be an eddy current proximity switch or a capacitive proximity switch, etc.

[0119] Optionally, a fourth detection element 251 may also be provided on the material hopper 25. The fourth detection element 251 is configured to detect the amount of dust contained in the material hopper 25. For example, the fourth detection element 251 may be a weighted level sensor, an ultrasonic level sensor, or a capacitive level sensor, etc.

[0120] In some embodiments, see Figure 4 As shown, the first processing chamber 20 may also be provided with a fifth detection element 28, which is configured to detect the temperature inside the first processing chamber 20 and issue an alarm when the temperature inside the first processing chamber 20 reaches a preset value.

[0121] For example, the structure of the fifth detection element 28 can be various, such as a thermocouple sensor, a thermistor sensor, or a resistance temperature detector.

[0122] According to some embodiments of this application, see Figure 4 As shown, the first filter element 40 has a hollow structure, the air intake space 21 is located outside the first filter element 40, and the exhaust space 22 is located inside the first filter element 40.

[0123] The intake space 21 is located outside the first filter element 40, and the exhaust space 22 is located inside the first filter element 40. In other words, the space formed inside the first filter element 40 is the exhaust space 22, and the space outside the first processing chamber 20 is the intake space 21.

[0124] For example, the first filter element 40 is a cylindrical hollow structure, that is, the first filter element 40 is a cylindrical hollow structure, with openings at both ends in the axial direction, and the two ends of the first filter element 40 abutting against the inner wall of the first processing chamber 20 respectively. Of course, in other embodiments, the first filter element 40 may also be a cuboid hollow structure or a prism hollow structure, etc.

[0125] By setting the first filter element 40 as a hollow structure, the space inside the first filter element 40 becomes the exhaust space 22, and the space outside the first filter element 40 becomes the intake space 21. The first filter element 40 with this structure can, on the one hand, increase the filtration area of ​​the gas entering the exhaust space 22 from the intake space 21, thereby improving the filtration effect of the dust removal device 100. On the other hand, when the blowing mechanism 30 back-blowing gas into the exhaust space 22 through the exhaust section 23, the gas can overflow from the exhaust space 22 into the intake space 21 from the periphery of the first filter element 40, thereby improving the cleaning effect of the blowing mechanism 30 on the first filter element 40 when back-blowing gas into the exhaust space 22.

[0126] In some embodiments, see Figure 3 and Figure 4 As shown, a plurality of first filter elements 40 are provided in the first processing chamber 20, and the exhaust space 22 inside each first filter element 40 is connected to an exhaust section 23.

[0127] For example, four first filter elements 40 are provided inside the first processing chamber 20, and the axes of the four first filter elements 40 are parallel to each other, so as to form four exhaust spaces 22 inside the first processing chamber 20. Of course, in other embodiments, the number of first filter elements 40 provided inside the first processing chamber 20 may also be two, three, five or six, etc.

[0128] By setting multiple first filter elements 40 in the first processing chamber 20, and each exhaust section 23 is connected to the exhaust space 22 of a first filter element 40, that is, each first filter element 40 is provided with an exhaust section 23, the efficiency of the dust removal device 100 in removing dust from the gas is improved.

[0129] According to some embodiments of this application, see Figure 4 As shown, the exhaust section 23 is a Venturi nozzle installed on the first processing chamber 20. The specific structure of the Venturi nozzle can be found in related technologies and will not be described further here.

[0130] Of course, in other embodiments, the exhaust section 23 may also be an exhaust port or exhaust valve provided on the first processing chamber 20.

[0131] By setting the exhaust section 23 as a Venturi nozzle connected to the first processing chamber 20, the exhaust section 23 with this structure is easy to install and has low pressure loss and good stability when the gas is discharged from the exhaust space 22 through the exhaust section 23. On the other hand, when the blowing mechanism 30 blows air back into the exhaust space 22 through the exhaust section 23, the gas has good flow and a large diffusion range, which is beneficial to improving the cleaning effect of the back-blown gas of the blowing mechanism 30 on the first filter element 40.

[0132] According to some embodiments of this application, see Figure 2 and Figure 4 As shown, the dust removal device 100 may also include a second processing chamber 50, an exhaust section 23 connecting the exhaust space 22 and the internal space of the second processing chamber 50, and an air blowing mechanism 30 disposed in the second processing chamber 50.

[0133] The exhaust section 23 connects the exhaust space 22 and the internal space of the second processing chamber 50. In other words, the exhaust section 23 is configured to discharge the gas in the exhaust space 22 of the first processing chamber 20 into the second processing chamber 50.

[0134] In some embodiments, the second processing chamber 50 may also be provided with a sixth detection element 51, which is configured to detect the air pressure inside the second processing chamber 50 and to issue an alarm when the air pressure inside the second processing chamber 50 reaches a preset value.

[0135] For example, the structure of the sixth detection element 51 can be various, such as a piezoresistive pressure sensor or a piezoelectric pressure sensor.

[0136] In some embodiments, see Figure 4 As shown, the second processing chamber 50 may also be provided with a seventh detection element 52, which is configured to detect the temperature inside the second processing chamber 50 and issue an alarm when the temperature inside the second processing chamber 50 reaches a preset value.

[0137] For example, the structure of the seventh detection element 52 can be various, such as a thermocouple sensor, a thermistor sensor, or a resistance temperature detector.

[0138] The dust removal device 100 is also provided with a second processing chamber 50. The second processing chamber 50 is connected to the exhaust space 22 of the first processing chamber 20 through the exhaust section 23, so that the gas in the exhaust space 22 can enter the second processing chamber 50 after passing through the exhaust section 23. By setting the blowing mechanism 30 in the second processing chamber 50, the blowing mechanism 30 can blow air into the interior of the exhaust section 23 to clean the first filter element 40 by reverse blowing. The second processing chamber 50 can also provide a certain degree of protection for the blowing mechanism 30 to reduce the risk of damage to the blowing mechanism 30.

[0139] According to some embodiments of this application, see Figure 4 As shown, the dust removal device 100 may also include an air extraction mechanism 60, which is connected to the internal space of the second processing chamber 50 and is configured to extract gas from the second processing chamber 50.

[0140] The dust removal device 100 may also include a first pipe 70, which connects the second processing chamber 50 and the air extraction mechanism 60, so that the air extraction mechanism 60 can extract the gas in the second processing chamber 50.

[0141] For example, the structure of the air extraction mechanism 60 can be various, such as a vortex high-pressure blower or a centrifugal blower.

[0142] In some embodiments, the dust removal device 100 may include a plurality of air extraction mechanisms 60, all of which are connected to the internal space of the second processing chamber 50.

[0143] In this configuration, multiple extraction mechanisms 60 are connected to the internal space of the second processing chamber 50 via a first pipe 70, thus achieving a parallel arrangement of the extraction mechanisms 60. This improves the extraction efficiency of the dust removal device 100, accelerating gas flow within it and enhancing its dust removal efficiency. Furthermore, the multiple extraction mechanisms 60 provide a backup function, ensuring that the normal operation of the dust removal device 100 is not affected by the failure of a single extraction mechanism 60, thereby increasing the operating rate of the dust removal device 100.

[0144] For example, the dust removal device 100 is provided with two air extraction mechanisms 60. Both air extraction mechanisms 60 are connected to the internal space of the second processing chamber 50 through the first pipe 70. Of course, in other embodiments, the number of air extraction mechanisms 60 can also be three, four or five, etc.

[0145] The dust removal device 100 is also equipped with an air extraction mechanism 60, which is connected to the internal space of the second processing chamber 50. The air extraction mechanism 60 can extract the gas in the second processing chamber 50 to improve the flow of the gas through the air inlet space 21, the exhaust space 22, the exhaust section 23 and the second processing chamber 50, which is beneficial to improving the dust removal efficiency of the dust removal device 100.

[0146] According to some embodiments of this application, see Figure 4 As shown, a second filter element 53 is provided inside the second processing chamber 50. The second filter element 53 is configured to filter dust in the gas entering the extraction mechanism 60 from the internal space of the second processing chamber 50.

[0147] The second filter element 53 filters dust from the gas entering the extraction mechanism 60 from the interior space of the second processing chamber 50. Specifically, the second filter element 53 can filter the gas entering the first pipe 70 from the interior space of the second processing chamber 50. The material of the second filter element 53 can be various, such as wood pulp fiber, glass fiber, or polytetrafluoroethylene. In some embodiments, the surface of the second filter element 53 is covered with a nanofiber layer, which helps to improve the filtration effect.

[0148] By installing a second filter element 53 in the second processing chamber 50, the second filter element 53 can filter dust in the gas entering the extraction mechanism 60 from the second processing chamber 50, thereby achieving further filtration of the gas and realizing a two-stage filtration structure for the dust removal device 100, which is conducive to improving the dust removal effect of the dust removal device 100.

[0149] According to some embodiments of this application, see Figure 2 and Figure 4 As shown, the dust removal device 100 may also include an installation chamber 80, and the air extraction mechanism 60 is disposed in the installation chamber 80.

[0150] The dust removal device 100 is also provided with an installation chamber 80, and the air extraction mechanism 60 is located inside the installation chamber 80, so that the installation chamber 80 can play a certain role in protecting the air extraction mechanism 60 and alleviate the risk of damage to the air extraction mechanism 60.

[0151] In some embodiments, see Figure 4 As shown, an installation base 81 is provided inside the installation chamber 80, an air extraction mechanism 60 is installed on the installation base 81, and a shock absorber 82 is provided between the air extraction mechanism 60 and the installation base 81.

[0152] The shock absorber 82 absorbs the vibration of the air extraction mechanism 60 to achieve the shock absorption effect. The shock absorber 82 can be made of various materials, such as rubber, silicone or plastic.

[0153] By providing a mounting base 81 for installing the air extraction mechanism 60 in the installation chamber 80, and providing a shock absorber 82 between the mounting base 81 and the air extraction mechanism 60, the vibration generated by the air extraction mechanism 60 during use can be mitigated, thereby reducing the impact and damage to the dust removal device 100 caused by the vibration of the air extraction mechanism 60, which is beneficial to improving the service life of the dust removal device 100.

[0154] According to some embodiments of this application, see Figure 2 and Figure 4 As shown, the dust removal device 100 may also include a silencing mechanism 90, which is connected to the exhaust port of the extraction mechanism 60.

[0155] The dust removal device 100 also includes a second pipe 61, which is connected to the exhaust port of the extraction mechanism 60 to discharge the gas extracted by the extraction mechanism 60. The silencer 90 is disposed in the second pipe 61 and is connected to the extraction mechanism 60 through the second pipe 61.

[0156] In some embodiments, see Figure 4 As shown, the silencing mechanism 90 includes a silencing chamber 91 and a silencing component 92. The silencing chamber 91 is connected to the exhaust port of the extraction mechanism 60 through a second pipe 61. The silencing component 92 is housed in the silencing chamber 91 and is configured to absorb noise in the gas discharged from the extraction mechanism 60.

[0157] For example, the silencing component 92 can be a porous structure housed within the silencing chamber 91, such as silencing cotton, sponge, or foam. The material of the silencing component 92 is a flame-retardant material, such as polyester fiber or polyurethane.

[0158] It should be noted that in other embodiments, the silencing mechanism 90 may also be a sound-absorbing cotton or silencer directly installed in the second pipe 61 or installed at the exhaust port of the air extraction mechanism 60.

[0159] The dust removal device 100 is also equipped with a silencing mechanism 90, which is connected to the exhaust port of the extraction mechanism 60, so that the silencing mechanism 90 can play a role in silencing the gas discharged by the extraction mechanism 60, thereby reducing the adverse effects of noise on production.

[0160] According to some embodiments of this application, see Figure 2 , Figure 3 and Figure 4 As shown, the first processing chamber 20 may also be provided with a first explosion relief mechanism 29, which is configured to release the internal pressure of the first processing chamber 20.

[0161] For example, the first explosion relief mechanism 29 is disposed on the top of the first processing chamber 20, and the structure of the first explosion relief mechanism 29 can be various, such as a flameless explosion relief device or explosion relief disc disposed on the first processing chamber 20.

[0162] The first processing chamber 20 is also equipped with a first explosion relief mechanism 29. When a fire or explosion occurs inside the first processing chamber 20, the first explosion relief mechanism 29 can release the internal pressure of the first processing chamber 20, thereby improving the safety of the dust removal device 100 and reducing damage to the dust removal device 100.

[0163] According to some embodiments of this application, see Figure 3 As shown, the dust removal device 100 may also include a flame arrester 18 and an air inlet pipe 10. The flame arrester 18 is disposed in the first processing chamber 20, and the air inlet pipe 10 is connected to the air inlet space 21 through the flame arrester 18. The air inlet pipe 10 is configured to input gas into the air inlet space 21.

[0164] The flame arrester 18 serves to prevent the flame in the air intake pipe 10 from entering the first processing chamber 20. The flame arrester 18 can have various structures, such as a filling type flame arrester, a plate type flame arrester, a metal mesh flame arrester, or a corrugated type flame arrester.

[0165] The dust removal device 100 is also provided with an air inlet pipe 10 that communicates with the air inlet space 21. The air inlet pipe 10 is connected to the air inlet space 21 of the first processing chamber 20 through a flame arrester 18 installed on the first processing chamber 20. In this way, when a fire occurs in the air inlet pipe 10, it can effectively prevent the flame from entering the air inlet space 21 and further causing the first processing chamber 20 to explode, thereby improving the safety of the dust removal device 100.

[0166] According to some embodiments of this application, see Figure 1As shown, this application embodiment provides a dust removal device 1000, which includes a powder sprayer 200 and a dust removal apparatus 100 according to any of the above embodiments. The powder sprayer 200 is connected to the first processing chamber 20 and is configured to provide inert powder into the air intake space 21. The specific structure of the powder sprayer 200 can be found in related technologies and will not be described in detail here.

[0167] The powder sprayer 200 has a delivery pipe 210, which is connected to the air inlet pipe 10 so that the powder sprayer 200 can provide inert powder to the air inlet space 21 of the first processing chamber 20 through the air inlet pipe 10.

[0168] The powder sprayer 200 provides inert powder into the air intake pipe 10, so that the inert powder can suppress the spontaneous combustion of dust after being sprayed into the air intake pipe 10. The inert powder provided by the powder sprayer 200 can be of various types, such as sodium bicarbonate powder or calcium carbonate powder.

[0169] By connecting the powder sprayer 200 to the air intake space 21 of the first processing chamber 20, the powder sprayer 200 can provide inert powder into the air intake space 21, so that the dust in the air intake space 21 can be mixed with the inert powder, thereby reducing the concentration of flammable and explosive dust in the gas, which is beneficial to suppressing dust spontaneous combustion, thereby reducing the risk of dust fire and explosion in the air intake space 21, and improving the safety of the dust removal equipment 1000.

[0170] According to some embodiments of this application, refer to Figure 1 Please refer to further details. Figure 5 , Figure 5 This is a partial structural schematic diagram of a dust removal device 1000 provided in some embodiments of this application. The dust removal device 1000 may further include a first detection unit (not shown) and a controller 300. The first detection unit is disposed within the powder sprayer 200 and is configured to detect the weight of the inerting powder within the powder sprayer 200. The controller 300 is electrically connected to the powder sprayer 200 and the first detection unit, and is used to adjust the powder output of the powder sprayer 200 based on the detection result of the first detection unit. The specific structure of the controller 300 can be found in related technologies and will not be described in detail here.

[0171] The first detection unit is located inside the powder sprayer 200. The first detection unit is responsible for detecting the weight of the inert powder inside the powder sprayer 200. The structure of the first detection unit can be various, such as grating type load cell, hydraulic type load cell, capacitive type load cell, electromagnetic force type load cell or encoder type load cell.

[0172] The controller 300 is used to adjust the powder output of the powder sprayer 200 according to the detection result of the first detection unit. That is, according to the weight of the inerting powder in the powder sprayer 200 fed back by the first detection unit, the controller 300 can record the weight change of the inerting powder in the powder sprayer 200 to obtain the powder output of the inerting powder sprayed into the air intake pipe 10 by the powder sprayer 200, so as to adjust the powder output of the powder sprayer 200 according to actual needs.

[0173] In some embodiments, a second detection unit (not shown) is provided inside the powder sprayer 200, the second detection unit being configured to detect the amount of inerting powder contained in the powder sprayer 200.

[0174] For example, the structure of the second detection unit can be various, such as a weighted level sensor, an ultrasonic level sensor, or a capacitive level sensor.

[0175] The dust removal equipment 1000 is also equipped with a first detection unit and a controller 300. By setting the first detection unit inside the powder sprayer 200, the first detection unit can detect the weight of the inerting powder inside the powder sprayer 200. This allows the controller 300 to adjust the amount of inerting powder supplied by the powder sprayer 200 to the air intake space 21 based on the weight change detected by the first detection unit. On the one hand, this can alleviate the phenomenon that the inerting powder is not effective in suppressing dust ignition and spontaneous combustion in the first treatment chamber 20 due to insufficient inerting powder supply. On the other hand, it can alleviate the phenomenon that excessive inerting powder supply leads to waste and excessive filtration pressure of the first filter element 40.

[0176] According to some embodiments of this application, this application provides a control method for a dust removal device 100, applicable to any of the above-described dust removal devices 100, see reference. Figure 2 , Figure 3 and Figure 4 Please refer to further details. Figure 6 , Figure 6 This is a schematic flowchart illustrating the control method of the dust removal device 100 provided in some embodiments of this application. The control method of the dust removal device 100 is as follows:

[0177] S100: Obtain the status parameters within the air intake space 21, including air pressure or dust concentration;

[0178] S200: If the state parameters in the intake space 21 are greater than or equal to the threshold, control the blowing mechanism 30 to run for a first preset time to blow air into the exhaust section 23.

[0179] In step S100, the state parameters of the air intake space 21 of the first processing chamber 20 are first obtained. The state parameters can be the air pressure in the air intake space 21 or the dust concentration in the air intake space 21. For example, in this embodiment of the application, the state parameter is the air pressure in the air intake space 21, that is, step S100 is to first obtain the air pressure in the air intake space 21.

[0180] In step S200, when the state parameter in the air intake space 21 is greater than or equal to the threshold, that is, when the air pressure in the air intake space 21 is greater than or equal to the threshold, the blowing mechanism 30 can be started and blow air into the exhaust space 22 through the exhaust section 23 for a first preset time. Conversely, if the air pressure in the air intake space 21 is lower than the threshold, the dust removal device 100 will operate normally.

[0181] For example, the first preset duration is 3 minutes. Of course, in other embodiments, the first preset duration may also be 1 minute, 2 minutes, 4 minutes, 5 minutes, or 6 minutes, etc.

[0182] In the above control method, the state parameters representing air pressure or dust concentration in the air intake space 21 of the first processing chamber 20 are first obtained to provide feedback on the dust accumulation on the first filter element 40. When the state parameters in the air intake space 21 reach a threshold, the blowing mechanism 30 can be controlled to run for a first preset time to blow air back into the air intake space 21 through the exhaust section 23, thereby achieving reverse blowing cleaning of the first filter element 40. This realizes the automatic control of the blowing mechanism 30, reduces manual intervention, and enables reverse blowing cleaning of the first filter element 40 according to actual usage conditions, thereby effectively improving the safety of the dust removal device 100.

[0183] According to some embodiments of this application, refer to Figure 2 , Figure 3 and Figure 4 Please refer to further details. Figure 7 , Figure 7 This is a flowchart illustrating the control method of a dust removal device 100 provided in some embodiments of this application. The dust removal device 100 also includes an air extraction mechanism 60, which is connected to the exhaust section 23. After step S200: if the state parameter in the air intake space 21 is greater than or equal to a threshold, the blowing mechanism 30 is controlled to run for a first preset time to blow air into the exhaust section 23, the control method of the dust removal device 100 may further include:

[0184] S300: After the blowing mechanism 30 has been running for a first preset time, the state parameters in the air intake space 21 are acquired again;

[0185] S400: If the state parameters in the air intake space 21 are not lower than the threshold, control the air extraction mechanism 60 to stop operating.

[0186] In step S300, after the blowing mechanism 30 has been running for a first preset time, the state parameters in the intake space 21 are acquired again. That is, after the blowing mechanism 30 blows air in the opposite direction into the exhaust space 22 through the exhaust section 23 for a first preset time, the state parameters in the intake space 21 are acquired again, that is, the air pressure in the intake space 21 is acquired again.

[0187] In step S400, if the state parameters in the air intake space 21 are still greater than or equal to the threshold, that is, the air pressure in the air intake space 21 is still greater than or equal to the threshold, the air extraction mechanism 60 stops operating to mitigate further risks. Conversely, if the air pressure in the air intake space 21 is lower than the threshold, the dust removal device 100 resumes normal operation.

[0188] In the above control method, after the blowing mechanism 30 blows air into the air intake space 21 through the exhaust section 23 for a first preset time, the state parameters of the air intake space 21 of the first processing chamber 20 are acquired again. If the state parameters representing the air pressure or dust concentration in the air intake space 21 still have not dropped below the threshold, the suction mechanism 60 of the dust removal device 100 is stopped, thereby alleviating the safety hazards caused by the further increase of air pressure in the air intake space 21, and thus improving the safety of the dust removal device 100.

[0189] According to some embodiments of this application, refer to Figure 2 , Figure 3 and Figure 4 Please refer to further details. Figure 8 , Figure 8 This is a flowchart illustrating the control method of a dust removal device 100 provided in some embodiments of this application. The dust removal device 100 also includes an air extraction mechanism 60, which is connected to the exhaust section 23. After obtaining the state parameters within the air intake space 21 in step S100, the control method of the dust removal device 100 may further include: if the state parameters within the air intake space 21 remain unchanged for a second preset time period, controlling the air extraction mechanism 60 to stop operating.

[0190] If the state parameters within the air intake space 21 remain unchanged for a second preset time period, that is, if the air pressure or dust concentration within the air intake space 21 of the first processing chamber 20 remains unchanged for a second preset time period, the air extraction mechanism 60 will stop operating to mitigate further risks.

[0191] In this embodiment of the application, if the air pressure in the air intake space 21 remains constant for a second preset time period, the air extraction mechanism 60 is controlled to stop operating.

[0192] For example, the second preset duration is 3 minutes. Of course, in other embodiments, the second preset duration can also be 1 minute, 2 minutes, 4 minutes, 5 minutes, or 6 minutes, etc.

[0193] In the above control method, after obtaining the state parameters representing the air pressure or dust concentration in the air intake space 21, it is also possible to determine whether the state parameters remain unchanged within a second preset time period based on the state parameters in the air intake space 21. If the state parameters remain unchanged, the dust removal device 100 may have component damage. Therefore, by stopping the air extraction mechanism 60, the further safety hazards of the dust removal device 100 can be alleviated.

[0194] According to some embodiments of this application, this application provides a control method for a dust removal device 1000, applicable to any of the above-described dust removal devices 1000, as shown in the figure. Figure 1 and Figure 5 Please refer to further details. Figure 9 , Figure 9 This is a flowchart illustrating the control method of a dust removal device 1000 provided in some embodiments of this application. The control method of the dust removal device 1000 is as follows:

[0195] S1000: Obtain the amount of powder dispensed by the powder sprayer 200 within a third preset time period;

[0196] S2000: If the powder output of the powder sprayer 200 is not within the preset range, adjust the powder output of the powder sprayer 200.

[0197] In step S1000, the amount of inerting powder supplied by the powder sprayer 200 into the air intake space 21 within a third preset time period is first obtained. There are various methods for obtaining this amount of powder. For example, the amount of inerting powder supplied by the powder sprayer 200 into the air intake pipe 10 can be obtained directly by detecting the amount of inerting powder sprayed into the air intake pipe 10 within a third preset time period. Alternatively, the amount of inerting powder supplied by the powder sprayer 200 into the air intake space 21 within a third preset time period can be obtained indirectly by obtaining the weight change of the inerting powder in the powder sprayer 200.

[0198] For example, the third preset duration is 1 hour. Of course, in other embodiments, the third preset duration can also be 0.5 hours, 1.5 hours, 2 hours, 2.5 hours, or 3 hours, etc.

[0199] In step S2000, when the amount of powder sprayed by the powder sprayer 200 within the third preset time period is not within the preset range, that is, when the amount of powder sprayed by the powder sprayer 200 within the third preset time period is greater than or less than the preset range, the controller 300 can reduce or increase the amount of powder sprayed by the powder sprayer 200 to adjust the amount of powder sprayed by the powder sprayer 200. Conversely, if the amount of powder sprayed by the powder sprayer 200 within the third preset time period is within the preset range, the dust removal equipment 1000 operates normally.

[0200] In the above control method, by obtaining the amount of powder output of the powder sprayer 200 within a third preset time period, the amount of inerting powder provided by the powder sprayer 200 to the air intake space 21 of the first processing chamber 20 is fed back. This allows the amount of inerting powder provided by the powder sprayer 200 to the air intake space 21 to be adjusted when the amount of powder output of the powder sprayer 200 is not within the preset range. On the one hand, this can alleviate the phenomenon that the inerting powder is not effective in suppressing dust ignition and spontaneous combustion in the first processing chamber 20 due to insufficient inerting powder supply. On the other hand, it can alleviate the phenomenon that excessive inerting powder supply leads to waste and excessive filtration pressure of the first filter element 40.

[0201] According to some embodiments of this application, refer to Figure 1 and Figure 5 Please refer to further details. Figure 10 , Figure 10 This is a flowchart illustrating the control method of a dust removal device 1000 provided in some embodiments of this application. The dust removal device 100 further includes an extraction mechanism 60, which is connected to an exhaust section 23. In step S2000: if the powder output of the powder sprayer 200 is not within a preset range, after adjusting the powder output of the powder sprayer 200, the control method of the dust removal device 1000 may further include:

[0202] S3000: Once again obtain the amount of powder dispensed by the powder sprayer 200 within the third preset time period;

[0203] S4000: If the powder output of the powder sprayer 200 is not within the preset range, control the air extraction mechanism 60 to stop operating.

[0204] In step S3000, after the controller 300 adjusts the powder output of the powder sprayer 200, the powder output of the powder sprayer 200 within the second and third preset time period is obtained again.

[0205] In step S4000, if the amount of powder output from the powder sprayer 200 is still not within the preset range within the second and third preset time periods, that is, if the amount of powder output from the powder sprayer 200 is still greater than or less than the preset range within the second and third preset time periods, the exhaust mechanism 60 stops operating to mitigate further risks. Conversely, if the amount of powder output from the powder sprayer 200 is within the preset range within the second and third preset time periods, the dust removal equipment 1000 resumes normal operation.

[0206] In the above control method, after adjusting the powder output of the powder sprayer 200, the powder output of the powder sprayer 200 is obtained again within a third preset time period. If the powder output of the powder sprayer 200 is still not within the preset range, the exhaust mechanism 60 of the dust removal device 100 is stopped, thereby alleviating the safety hazards caused by too much or too little inerting powder, and thus improving the safety of the dust removal equipment 1000.

[0207] In some embodiments, the amount of powder dispensed by the powder sprayer 200 during the third preset time period is obtained based on the weight change of the inerting powder in the powder sprayer 200 during the third preset time period. That is, the amount of powder dispensed by the powder sprayer 200 during the third preset time period is obtained by recording the amount of weight reduction of the inerting powder in the powder sprayer 200 during the third preset time period. If the amount of weight reduction of the inerting powder is divided by the third preset time period, the amount of powder sprayed by the powder sprayer 200 per unit time is obtained.

[0208] In the above control method, the amount of powder output from the powder sprayer 200 within the third preset time period is calculated and obtained by acquiring the weight change of the inerting powder in the powder sprayer 200 within the third preset time period. This method is easy to implement and operate, and helps to reduce programming costs.
