Description

Technical Field

[0001] This application relates to the field of dust removal technology, and more specifically, to a dust removal device. Background Technology

[0002] During the operation of combustion-type heat treatment equipment, the high-temperature preparation of materials undergoes a boiling reaction, generating a large amount of furnace ash that needs to be cleaned promptly. Current ash removal processes are inconvenient and easily allow external air to enter the equipment, making it difficult to maintain a good seal between the internal and external environments, thus affecting the stability and reliability of the combustion-type heat treatment equipment. Utility Model Content

[0003] This application provides a dust removal device that can improve the sealing performance of combustion heat treatment equipment during the dust removal process, reduce the difficulty of dust removal, and improve the stability and reliability of combustion heat treatment equipment.

[0004] In a first aspect, this application provides a dust removal device applied to a combustion-type heat treatment device, comprising: a transmission device for providing driving force; a dust removal device located at the bottom of the heat treatment chamber of the combustion-type heat treatment device and connected to the transmission device; and a dust receiving device including a first plate valve and a second plate valve, the first plate valve and the second plate valve covering the ash discharge port at the bottom of the heat treatment chamber, the second plate valve being located on the side of the first plate valve away from the heat treatment chamber; wherein, the transmission device drives the dust removal device to move to remove furnace ash from the bottom of the heat treatment chamber, the first plate valve is opened when furnace ash is discharged, and the second plate valve is opened after the first plate valve is closed.

[0005] In the technical solution of this application embodiment, the ash removal device is driven by a transmission device to move at the bottom of the heat treatment chamber for ash removal. This can effectively and promptly remove the furnace ash at the bottom of the heat treatment chamber, maintain good heat conduction performance of the heat treatment chamber, and make the heating and heat preservation process of the combustion heat treatment equipment more stable and efficient, ensuring the consistency and stability of the product heat treatment quality. The second plate valve opens after the first plate valve closes, which can prevent external impurities, dust, air, etc. from entering the area between the first and second plate valves through the ash discharge port in the reverse direction. This prevents these impurities from entering the heat treatment chamber when the first plate valve is open, and also enhances the sealing effect of the entire ash discharge port, reducing heat loss and dust leakage.

[0006] In some embodiments of the first aspect, the ash receiving device further includes an ash hopper located on the side of the ash discharge port at the bottom of the heat treatment chamber away from the heat treatment chamber, for receiving furnace ash discharged from the ash discharge port.

[0007] In this embodiment, the furnace ash is collected by the ash hopper, which serves to centrally collect the furnace ash, making it easier for subsequent unified processing. This avoids the situation where the furnace ash is scattered everywhere after being discharged, polluting the surrounding environment of the equipment or re-entering the heat treatment chamber, and effectively realizes the fixed-point collection of furnace ash.

[0008] In some embodiments of the first aspect, the ash receiving device further includes a nitrogen filling pipe connected to a nitrogen gas source for filling the ash hopper with nitrogen gas.

[0009] In this embodiment of the application, by filling the ash hopper with nitrogen, the ash hopper can be kept in a slightly positive pressure state. During the process of furnace ash falling from the heat treatment chamber into the ash hopper, the possibility of external air entering the heat treatment chamber is reduced, thus affecting the quality and effect of heat treatment.

[0010] In some embodiments of the first aspect, the nitrogen-filling pipe extends along a first direction, and the nitrogen-filling pipe is oriented toward the first direction and / or the second direction; wherein the first direction is perpendicular to the movement direction of the dust removal device and parallel to the bottom of the heat treatment chamber, and the second direction is the movement direction of the dust removal device.

[0011] In this embodiment, the nitrogen filling pipe is circumvented in a direction that avoids the direction in which the ash falls from the ash discharge port. This is to prevent the nitrogen gas flow from directly impacting the falling ash, which could cause the ash's trajectory to become disordered, potentially leading to problems such as ash splashing out of the ash hopper or uneven dispersion within the ash hopper, thus affecting the normal collection and subsequent processing of the ash.

[0012] In some embodiments of the first aspect, the ash receiving device further includes a nitrogen charging valve connected to a nitrogen charging pipe for controlling the charging of nitrogen gas.

[0013] In this embodiment, the nitrogen charging valve, as a control switch for nitrogen charging, can conveniently realize the opening and closing operation of nitrogen charging, effectively prevent nitrogen waste, and flexibly control the nitrogen to be charged into the ash hopper at the appropriate time.

[0014] In some embodiments of the first aspect, the projected area of ​​the ash hopper toward the bottom of the heat treatment chamber is greater than the projected area of ​​the ash discharge port toward the bottom of the heat treatment chamber.

[0015] In this embodiment, the cross-sectional area of ​​the ash hopper is larger than that of the ash discharge port. Even if the discharge direction and speed of the furnace ash discharged from the ash discharge port change, there is a greater probability that it will be received by the ash hopper. This prevents furnace ash from overflowing from the edges, ensuring that the furnace ash is accurately collected in the ash hopper and maintaining the cleanliness of the surrounding environment.

[0016] In some embodiments of the first aspect, the ash receiving device further includes a ash removal port for discharging dust from the ash hopper.

[0017] In this embodiment of the application, cleaning the furnace ash through the ash removal port can maintain the normal ash storage capacity of the ash hopper, ensure that it can continuously and effectively receive the furnace ash discharged from the heat treatment chamber, and ensure the normal operation of the entire ash removal equipment.

[0018] In some embodiments of the first aspect, the ash receiving device further includes a cover plate that covers the ash removal port.

[0019] In this embodiment, the main function of the cover plate is to seal the ash removal port. During normal operation of the ash receiving device, the cover plate tightly covers the ash removal port to prevent furnace ash in the ash hopper from leaking out of the ash removal port, thus avoiding pollution to the surrounding environment. At the same time, it can also prevent external dust, impurities, etc. from entering the ash hopper, thus avoiding affecting the normal collection and subsequent processing of furnace ash.

[0020] In some embodiments of the first aspect, the dust removal device includes at least two connection points, which are evenly distributed along a first direction, and the dust removal device is connected to the transmission device at the at least two connection points; wherein the first direction is perpendicular to the movement direction of the dust removal device and parallel to the bottom of the heat treatment chamber.

[0021] In this embodiment, the transmission device and the dust removal device are connected at least two connection points. When the transmission device applies a driving force to the dust removal device, each connection point can share the force in concert, so that the dust removal device can always maintain a good fit with the bottom of the heat treatment chamber during the movement and continue to move in the same direction. This is beneficial to maintaining the accuracy and continuity of the dust removal action and achieving a stable and efficient dust removal operation.

[0022] In some embodiments of the first aspect, the transmission device includes a motor and a connecting rope. The motor is located outside the combustion heat treatment equipment. The motor includes a drive shaft. One end of the connecting rope is wound around the drive shaft, and the other end of the connecting rope is connected to a dust removal device. The drive shaft drives the dust removal device to move toward the drive shaft by rotation.

[0023] In this embodiment, the rotational speed of the drive shaft is controlled by a motor, and the rotation of the drive shaft drives the dust removal device to move toward the drive shaft, thereby controlling the movement speed of the dust removal device.

[0024] In some embodiments of the first aspect, the motor includes a first motor and a second motor, and the connecting rope includes a first connecting rope and a second connecting rope. The first motor and the second motor are located on both sides of the combustion heat treatment equipment along a second direction. The first motor is connected to the ash removal device through the first connecting rope, and the second motor is connected to the ash removal device through the second connecting rope. The first motor and the second motor drive the ash removal device to move in the opposite direction of the second direction; wherein, the second direction is the direction of movement of the ash removal device.

[0025] In this embodiment, by installing a first motor and a second motor in the combustion heat treatment equipment, the first motor and the second motor can drive the ash cleaning device to reciprocate through the scaling of the first connecting rope and the second connecting rope, repeatedly cleaning the furnace ash at different locations, avoiding the dead corners that may exist in a single unidirectional movement, and greatly improving the comprehensiveness and thoroughness of ash cleaning.

[0026] In some embodiments of the first aspect, the dust removal device extends along a first direction, and the ratio of the dimension of the dust removal device along the first direction to the dimension of the heat treatment chamber along the first direction is greater than or equal to 2 / 3 and less than 1; wherein the first direction is perpendicular to the moving direction of the dust removal device and parallel to the bottom of the heat treatment chamber.

[0027] In this embodiment, by adjusting the ratio of the dimension of the ash-cleaning device along the first direction to the dimension of the heat treatment chamber along the first direction, the device can more evenly clean the furnace ash across the entire width range during movement. This ensures more uniform cleaning of the furnace ash at the bottom of the heat treatment chamber, guaranteeing the stability of the material's heat treatment quality.

[0028] In some embodiments of the first aspect, the material of the dust removal device includes high-temperature resistant metal materials.

[0029] In this embodiment, the material of the dust removal device may include stainless steel, heat-resistant steel, or high-temperature alloy. Good high-temperature strength and oxidation resistance ensure reliable operation of the dust removal device.

[0030] In some embodiments of the first aspect, the dust removal equipment further includes a controller, which includes a dust removal control module for activating a transmission device to drive the dust removal device to move at the bottom of the heat treatment chamber of the combustion heat treatment equipment; a first ash receiving control module for opening a first plate valve of the dust removal equipment when the dust removal device moves to the ash discharge port at the bottom of the heat treatment chamber, so that the furnace ash falls onto a second plate valve of the dust removal equipment; and a second ash receiving control module for opening the second plate valve when the first plate valve is closed, so that the furnace ash falls into the ash hopper.

[0031] In this embodiment, the entire dust removal equipment is controlled by a controller, which coordinates the work of various components such as the dust removal device and the transmission device, so that they work together in a predetermined logical sequence and time node, thereby improving the coordination and work efficiency of the dust removal equipment.

[0056] During the operation of combustion-type heat treatment equipment, the high-temperature preparation of materials undergoes a boiling reaction, generating a large amount of furnace ash that needs to be cleaned promptly. Current ash removal processes are inconvenient and easily allow external air to enter the equipment, making it difficult to maintain a good seal between the internal and external environments, thus affecting the stability and reliability of the combustion-type heat treatment equipment.

[0057] Based on the above considerations, this application provides a dust removal device that improves the sealing performance of the combustion heat treatment equipment during the dust removal process, reduces the difficulty of ash removal, and enhances the stability and reliability of the combustion heat treatment equipment. The dust removal device provided in this application is applied to a combustion heat treatment equipment. The dust removal device includes a transmission device and a ash removal device. The transmission device provides driving force; the ash removal device is located at the bottom of the heat treatment chamber of the combustion heat treatment equipment and is connected to the transmission device; the ash receiving device includes a first plate valve and a second plate valve, which cover the ash discharge port at the bottom of the heat treatment chamber. The second plate valve is located on the side of the first plate valve away from the heat treatment chamber. The transmission device drives the ash removal device to move, thereby removing furnace ash from the bottom of the heat treatment chamber. The first plate valve opens when furnace ash is discharged, and the second plate valve opens after the first plate valve closes.

[0058] In the technical solution of this application embodiment, the ash removal device is driven by a transmission device to move at the bottom of the heat treatment chamber for ash removal. This can effectively and promptly remove the furnace ash at the bottom of the heat treatment chamber, maintain good heat conduction performance of the heat treatment chamber, and make the heating and heat preservation process of the combustion heat treatment equipment more stable and efficient, ensuring the consistency and stability of the product heat treatment quality. The second plate valve opens after the first plate valve closes, which can prevent external impurities, dust, air, etc. from entering the area between the first and second plate valves through the ash discharge port in the reverse direction. This prevents these impurities from entering the heat treatment chamber when the first plate valve is open, and also enhances the sealing effect of the entire ash discharge port, reducing heat loss and dust leakage.

[0059] Figure 1 This is a structural diagram of a dust removal device according to an embodiment of this application. Figure 1 As shown, the dust removal equipment is applied to the combustion heat treatment equipment 10. The dust removal equipment includes a transmission device 1, a dust removal device 2, and a dust receiving device 3. The transmission device 1 is used to provide driving force. The dust removal device 2 is located at the bottom of the heat treatment chamber 101 of the combustion heat treatment equipment 10 and is connected to the transmission device 1. The dust receiving device 3 includes a first plate valve 31 and a second plate valve 32. The first plate valve 31 and the second plate valve 32 cover the ash discharge port 102 at the bottom of the heat treatment chamber 101. The second plate valve 32 is located on the side of the first plate valve 31 away from the heat treatment chamber 101. The transmission device 1 drives the dust removal device 2 to move to remove the furnace ash at the bottom of the heat treatment chamber 101. The first plate valve 31 is used to open when the furnace ash is discharged, and the second plate valve 32 is opened after the first plate valve 31 is closed.

[0060] It should be understood that the combustion-type heat treatment equipment 10 uses various fuels as energy sources, such as natural gas, coal gas, heavy oil, and coal. The fuel mixes with air in a dedicated burner and undergoes a combustion reaction, releasing a large amount of heat energy. The heat treatment process involves keeping the material in a high-temperature environment for a certain period of time, causing structural transformations and property changes, such as quenching, tempering, normalizing, and annealing, to improve the material's mechanical properties and processing performance.

[0061] In this embodiment, for example, the combustion-type heat treatment equipment 10 may include a roller furnace. The furnace body has a tunnel-type structure with multiple rollers inside. Materials are placed on the rollers, and continuous conveying of materials within the furnace is achieved through the continuous rotation of the rollers. Burners are arranged on both sides or the top of the furnace to heat the materials. Roller furnaces are suitable for the heat treatment of small parts produced in large quantities, such as bearing parts, standard parts, and electronic components. They can realize continuous automated operation of various heat treatment processes such as quenching, tempering, and normalizing.

[0062] In this application embodiment, for example, a roller furnace can be used to produce the positive electrode active material in a battery cell. The positive electrode active material may include at least one of the following materials: lithium phosphate, lithium transition metal oxide, and their respective modified compounds. However, this application is not limited to these materials, and other conventional materials that can be used as battery positive electrode active materials may also be used. These positive electrode active materials may be used alone or in combination of two or more. Examples of lithium phosphate may include, but are not limited to, at least one of lithium iron phosphate (such as LiFePO4 (also referred to as LFP)), lithium iron phosphate and carbon composites, lithium manganese phosphate (such as LiMnPO4), lithium manganese phosphate and carbon composites, lithium iron manganese phosphate, and lithium iron manganese phosphate and carbon composites. Examples of lithium transition metal oxide may include, but are not limited to, lithium cobalt oxide (such as LiCoO2), lithium nickel oxide (such as LiNiO2), lithium manganese oxide (such as LiMnO2, LiMn2O4), lithium nickel cobalt oxide, lithium manganese cobalt oxide, lithium nickel manganese oxide, and lithium nickel cobalt manganese oxide (such as LiNi). 1 / 3 Co 1 / 3 Mn 1 / 3 O2 (also known as NCM) 333 LiNi 0.5 Co 0.2 Mn 0.3 O2 (also known as NCM) 523 LiNi 0.5 Co 0.25 Mn 0.25 O2 (also known as NCM) 211 LiNi 0.6 Co 0.2 Mn 0.2 O2 (also known as NCM) 622 LiNi 0.8 Co 0.1 Mn 0.1 O2 (also known as NCM) 811 ), lithium nickel cobalt aluminum oxide (such as LiNi) 0.8 Co 0.15 Al 0.05 At least one of O2 and its modified compounds. Modified compounds refer to substances obtained by modification methods such as doping or coating based on the above-mentioned substances.

[0063] It should be understood that during the operation of the combustion heat treatment equipment 10, the combustion of materials within the heat treatment chamber 101 triggers a series of complex physical and chemical changes. The interaction of impurities in the materials and incomplete combustion reactions results in the generation of furnace ash within the heat treatment chamber 101. This furnace ash may contain unburned material particles and various mineral compounds and metal oxides generated by high-temperature oxidation, reduction, and other chemical reactions. As the combustion heat treatment equipment 10 continues to operate, the furnace ash will gradually accumulate at the bottom of the chamber and in other areas.

[0064] In this embodiment, the transmission device 1 includes a power source and has a stable and adjustable driving force output capability.

[0065] It should be understood that the transmission device 1 can adopt various driving forms, such as motor drive combined with chain drive, gear drive or screw and nut drive, so as to accurately transmit power to the dust removal device 2.

[0066] In this embodiment of the application, the magnitude and direction of the driving force of the transmission device 1 can be flexibly adjusted based on factors such as the degree of ash accumulation and the operating status of the equipment through a reasonable control strategy.

[0067] In this embodiment, since the furnace ash settles naturally under gravity, the ash removal device 2 is located at the bottom of the heat treatment chamber 101 to clean the furnace ash.

[0068] It should be understood that, for example, the moving direction and path of the ash removal device 2 can fully cover all areas at the bottom of the heat treatment chamber 101, so as to clean the furnace ash as thoroughly as possible.

[0069] In this embodiment of the application, the structure of the dust removal device 2 may include a scraper, a brush, an airflow purging device, or a combination thereof, etc.

[0070] In this embodiment, after the combustion heat treatment equipment 10 has been running for a period of time, the transmission device 1 is started. The transmission device 1 drives the ash removal device 2 to contact the furnace ash at the bottom of the heat treatment chamber 101, scraping up the furnace ash and pushing it to one side.

[0071] In this embodiment, the transmission device 1 can be started according to a preset time interval, or it can be started when the sensor detects that the furnace ash accumulation at the bottom of the chamber has reached a certain thickness.

[0072] It should be understood that the bottom of the heat treatment chamber 101 may include multiple ash discharge ports 102. For example, the ash discharge ports 102 may be close to the transmission device 1 and evenly distributed along the first direction.

[0073] It should be understood that the shape of the ash discharge port 102 can be rectangular or circular, and this application does not limit it.

[0074] It should be understood that the size and number of ash discharge ports 102 can be designed according to the size of the heat treatment chamber 101, and this application does not limit them.

[0075] It should be understood that the first plate valve 31 can be a flat plate component with a certain strength and sealing performance. Its material is generally selected from metal materials, such as carbon steel and stainless steel, to ensure that it can withstand the impact of furnace ash and wear during long-term use.

[0076] It should be understood that the shape and size of the first plate valve 31 are designed to be adapted to the shape and size of the ash discharge port 102, with the aim of covering the ash discharge port 102 and ensuring an effective seal when closed.

[0077] It should be understood that the second plate valve 32 is similar to the first plate valve 31. It can be a flat plate component with a certain strength and sealing performance. Its material is generally metal, such as carbon steel or stainless steel, to ensure that it can withstand the impact of furnace ash and wear during long-term use.

[0078] It should be understood that the shape and size of the second plate valve 32 are designed to be adapted to the shape and size of the ash discharge port 102, so as to cover the ash discharge port 102 and ensure that an effective seal can still be formed when the first plate valve 31 is open.

[0079] In this embodiment, the second plate valve 32 and the first plate valve 31 may be completely identical, or they may differ in material, size or shape. This application does not impose any limitations.

[0080] It should be understood that the first plate valve 31 and the second plate valve 32 can be a certain distance apart along the height direction of the heat treatment chamber 101, that is, there is a certain space between the first plate valve 31 and the second plate valve 32, so that furnace ash can fall from the first plate valve 31 into the second plate valve 32, and that this space can accommodate all the furnace ash after the first plate valve 31 is closed. The distance between the first plate valve 31 and the second plate valve 32 is determined by the size of the heat treatment chamber 101 and the ash discharge rate.

[0081] In this embodiment, during most of the operation of the combustion heat treatment equipment 10, when it is not necessary to discharge furnace ash, the first plate valve 31 and the second plate valve 32 are in the closed state to prevent external air, dust and other impurities from entering the heat treatment chamber 101 through the ash discharge port 102, thereby ensuring the stability of the heat treatment process and the consistency of material quality.

[0082] In this embodiment, when it is necessary to discharge furnace ash, the first plate valve 31 is opened, and the furnace ash is discharged from the ash discharge port 102. At this time, the second plate valve 32 is still closed, and the furnace ash falls onto the second plate valve 32 through the ash discharge port 102. After the ash discharge is completed, the first plate valve 31 is closed, the second plate valve 32 is opened, and the furnace ash falls from the second plate valve 32 into the ash hopper 33.

[0083] In this embodiment, the first plate valve 31 can be controlled by a solenoid valve, which can control the opening and closing of the first plate valve 31 through an electrical signal. During the ash removal process of the dust removal equipment, the opening and closing time of the first plate valve 31 can be controlled according to a preset program or the ash accumulation detected by the sensor, to ensure that the ash is discharged at the appropriate time and avoid problems such as untimely ash treatment or excessive heat loss caused by ash discharge too early or too late.

[0084] In this embodiment, the second plate valve 32 can also be controlled by a solenoid valve. The solenoid valve can control the opening and closing of the first plate valve 31 and the second plate valve 32 through an electrical signal. During the ash removal process of the dust removal equipment, the opening and closing times of the first plate valve 31 and the second plate valve 32 can be controlled according to a preset program or the ash accumulation detected by the sensor, ensuring that the ash is discharged at the appropriate time and preventing air from entering the heat treatment chamber 101.

[0085] In this embodiment, during the operation of the combustion heat treatment equipment 10, the temperature inside the heat treatment chamber 101 is extremely high, and there is a risk of harmful gas leakage. Traditional manual cleaning methods require operators to enter the heat treatment chamber 101 after the equipment has been shut down and cooled, which not only consumes a significant amount of time waiting for cooling but also exposes operators to safety hazards such as burns from high temperatures and poisoning from harmful gases while working inside the chamber. However, this dust removal equipment uses a transmission device 1 to drive the cleaning device 2 to move at the bottom of the heat treatment chamber 101 for cleaning. This effectively and promptly removes furnace ash from the bottom of the heat treatment chamber 101, maintaining good thermal conductivity and making the heating and heat preservation process of the combustion heat treatment equipment 10 more stable and efficient, ensuring the consistency and stability of the product's heat treatment quality. Simultaneously, operators do not need to enter the high-temperature, dangerous chamber environment, greatly improving the safety of the cleaning operation, reducing the difficulty of cleaning, and protecting the health and safety of the operators.

[0086] In this embodiment, the design of opening the second plate valve 32 after the first plate valve 31 is closed provides a dual sealing mechanism for the entire dust removal equipment. The opening of the second plate valve 32 after the first plate valve 31 is closed prevents external impurities, dust, and air from entering the area between the first plate valve 31 and the second plate valve 32 through the ash discharge port 102. This avoids these impurities from subsequently entering the heat treatment chamber 101 when the first plate valve 31 is open, further ensuring the purity of the chamber environment. It also enhances the sealing effect at the entire ash discharge port 102, reducing heat loss and dust leakage.

[0087] Figure 2 This is another structural diagram of the dust removal equipment according to an embodiment of this application. Figure 3 This is a partial structural diagram of the dust removal equipment according to an embodiment of this application. Figure 2 and Figure 3 As shown, the ash receiving device 3 includes an ash hopper 33, which is located on the side of the ash discharge port 102 at the bottom of the heat treatment chamber 101 away from the heat treatment chamber 101, and is used to receive the furnace ash discharged from the ash discharge port 102.

[0088] In this embodiment, the ash hopper 33 is located on the side of the ash discharge port 102 at the bottom of the heat treatment chamber 101 that is away from the heat treatment chamber 101, that is, the ash hopper 33 is located below the ash discharge port 102, so that the furnace ash discharged from the ash discharge port 102 can fall directly into the ash hopper 33 under its own gravity and possible airflow pushing.

[0089] In this embodiment of the application, when installing the ash hopper 33, the ash hopper 33 should be aligned with the ash discharge port 102 at the bottom of the heat treatment chamber 101, and the connection between the two should be well sealed to prevent furnace ash from leaking from the gaps.

[0090] In this embodiment, the ash hopper 33 and the heat treatment chamber 101 can be connected by means of flange connection, welding, etc., and the connection parts should be checked for sealing after installation to ensure that the furnace ash can enter the ash hopper 33 smoothly and without leakage.

[0091] In this embodiment, the ash hopper 33 collects furnace ash, which serves to centrally collect the ash, facilitating subsequent unified processing and preventing the ash from scattering everywhere after discharge, polluting the surrounding environment, or re-entering the heat treatment chamber 101. This effectively achieves targeted collection of furnace ash, maintains the cleanliness of the surrounding environment, and reduces environmental pollution caused by scattered furnace ash and its impact on other equipment components.

[0092] Figure 4 This is another partial structural diagram of the dust removal equipment according to an embodiment of this application. Figure 4As shown, the ash receiving device 3 also includes a nitrogen filling pipe 34, which is connected to a nitrogen gas source and is used to fill the ash hopper 33 with nitrogen gas.

[0093] It should be understood that the nitrogen filling pipe 34 can be made of high-temperature and corrosion-resistant metal materials, such as stainless steel pipe, to ensure stable operation in the high-temperature and dusty environment where the ash hopper 33 is located.

[0094] It should be understood that the size of the nitrogen filling pipe 34 can be determined based on factors such as actual nitrogen filling requirements and the size of the ash hopper 33, and this application does not impose any restrictions.

[0095] In this embodiment, one end of the nitrogen filling pipe 34 is tightly connected to the nitrogen source, and the connection is sealed, such as by a flange connection and a sealing gasket, to prevent nitrogen leakage.

[0096] In this embodiment, the other end of the nitrogen filling pipe 34 extends into the ash hopper 33, for example, by opening a hole on the side of the ash hopper 33 to ensure that nitrogen can be filled into the ash hopper 33.

[0097] In this embodiment of the application, when the furnace ash needs to be discharged from the heat treatment chamber 101, the first plate valve 31 is opened, and at this time, nitrogen gas is started to be charged into the ash hopper 33 until the second plate valve 32 is closed.

[0098] In this embodiment, a solenoid valve may be installed on the nitrogen filling pipe 34, which is associated with the solenoid valves of the first plate valve 31 and the second plate valve 32. The solenoid valve can control the filling of nitrogen through an electrical signal.

[0099] In this embodiment, by filling the ash hopper 33 with nitrogen, the ash hopper 33 can be kept in a slightly positive pressure state. During the process of furnace ash falling from the heat treatment chamber 101 into the ash hopper 33, the possibility of external air entering the heat treatment chamber 101 is reduced, thus affecting the quality and effect of heat treatment.

[0100] In this embodiment, the nitrogen filling pipe 34 extends along a first direction, and the nitrogen filling direction of the nitrogen filling pipe 34 is oriented towards the first direction and / or the second direction; wherein, the first direction is perpendicular to the moving direction of the dust removal device 2 and parallel to the bottom of the heat treatment chamber 101, and the second direction is the moving direction of the dust removal device 2.

[0101] It should be understood that the nitrogen filling pipe 34 extends along the first direction. For example, the nitrogen filling pipe 34 may extend close to the inner wall of the ash hopper 33. Or, for example, the nitrogen filling pipe 34 may extend along the second direction to the middle of the ash hopper 33 and then extend along the first direction.

[0102] It should be understood that the nitrogen filling pipe 34 can be oriented towards the first direction, or towards the second direction, or towards both the first and second directions, that is, avoiding the direction in which furnace ash falls from the ash discharge port 102.

[0103] In this embodiment, the nitrogen filling direction of the nitrogen filling pipe 34 avoids the direction in which the ash falls from the ash discharge port 102. This is to prevent the nitrogen gas flow from directly impacting the falling ash, which could cause the ash's trajectory to become disordered, potentially leading to problems such as ash splashing out of the ash hopper 33 or uneven dispersion within the ash hopper 33, thus affecting the normal collection and subsequent processing of the ash. By following a reasonable filling direction, nitrogen can better perform its protective and auxiliary ash discharge functions within the ash hopper 33 without interfering with the ash's fall, ensuring the orderly operation of the ash receiving device 3.

[0104] Figure 5 This is another partial structural diagram of the dust removal device according to an embodiment of this application. Figure 5 As shown, the ash receiving device 3 also includes a nitrogen charging valve 35, which is connected to a nitrogen charging pipe 34 and is used to control the charging of nitrogen.

[0105] It should be understood that the nitrogen charging valve 35 can be used as a switch for nitrogen charging, realizing the opening and closing control of nitrogen charging. For example, when nitrogen needs to be charged into the ash hopper 33, the nitrogen charging valve 35 is opened, and nitrogen can flow into the ash hopper 33 along the nitrogen charging pipe 34; when nitrogen charging is not needed, the nitrogen charging valve 35 is closed to cut off the flow path of nitrogen, prevent nitrogen leakage, and avoid unnecessary nitrogen consumption.

[0106] It should be understood that the nitrogen charging valve 35 can regulate the nitrogen charging flow rate. By manually or automatically changing the flow cross-sectional area between the valve core and the valve seat, the flow rate of nitrogen entering the nitrogen charging pipeline 34 and finally charging the ash hopper 33 through the nitrogen charging valve 35 per unit time can be controlled.

[0107] In this embodiment, the nitrogen filling valve 35 can be connected to a solenoid valve, and by receiving signals from a sensor, the opening, closing and flow regulation of the nitrogen filling valve 35 can be automatically controlled according to a preset program.

[0108] In this embodiment, the nitrogen charging valve 35, as a control switch for nitrogen charging, can conveniently realize the opening and closing operation of nitrogen charging, effectively prevent nitrogen waste, and can also flexibly control the nitrogen to be charged into the ash hopper 33 at the appropriate time.

[0109] In this embodiment, the projected area of ​​the ash hopper 33 toward the bottom of the heat treatment chamber 101 is greater than the projected area of ​​the ash discharge port 102 toward the bottom of the heat treatment chamber 101.

[0110] It should be understood that the projected area of ​​the ash hopper 33 toward the bottom of the heat treatment chamber 101 is greater than the projected area of ​​the ash discharge port 102 toward the bottom of the heat treatment chamber 101, that is, the minimum cross-sectional area of ​​the ash hopper 33 is greater than the maximum cross-sectional area of ​​the ash discharge port 102, and this cross-section is parallel to the bottom of the heat treatment chamber 101.

[0111] It should be understood that the ash hopper 33 covers the ash discharge port 102 at the bottom of the heat treatment chamber 101.

[0112] In this embodiment, the cross-sectional area of ​​the ash hopper 33 is larger than that of the ash discharge port 102. Even if the discharge direction and speed of the furnace ash discharged from the ash discharge port 102 change, there is a greater probability that it will be received by the ash hopper 33. This prevents the furnace ash from overflowing from the edges and ensures that the furnace ash can be accurately collected in the ash hopper 33, maintaining the cleanliness of the surrounding environment of the equipment.

[0113] In this embodiment of the application, the ash receiving device 3 further includes a ash cleaning port 36, which is used to discharge the dust in the ash hopper 33.

[0114] It should be understood that the dust removal port 36 can be an opening made on the wall of the dust hopper 33 for discharging dust from the dust hopper 33.

[0115] In this embodiment, the ash removal port 36 can be located at the bottom or lower side of the ash hopper 33. This facilitates the natural flow of furnace ash accumulated in the ash hopper 33 towards the ash removal port 36 by gravity, making it easier to discharge.

[0116] It should be understood that the shape of the ash removal port 36 can be circular or rectangular, and this application does not limit it.

[0117] In this embodiment of the application, after the ash receiving process is completed and both the first plate valve 31 and the second plate valve 32 are closed, the furnace ash in the ash hopper 33 can be cleaned by a dust suction device through the ash cleaning port 36.

[0118] In this embodiment of the application, after the ash receiving device 3 has been running for a period of time, a certain amount of furnace ash will accumulate in the ash hopper 33. When the amount of furnace ash reaches a certain level, it is necessary to discharge the furnace ash through the ash cleaning port 36 in order to maintain the normal ash storage capacity of the ash hopper 33, ensure that it continuously and effectively receives the furnace ash discharged from the heat treatment chamber 101, and ensure the normal operation of the entire ash cleaning equipment.

[0119] In this embodiment of the application, cleaning furnace ash through the ash removal port 36 can reduce the safety risks of high-temperature burns, heat radiation, poisoning, and suffocation caused by manual online ash removal operations.

[0120] In this embodiment of the application, cleaning furnace ash through the ash removal port 36 can also save the frequency and time of cleaning in the workshop.

[0121] Figure 6 This is another partial structural diagram of the dust removal device according to an embodiment of this application. Figure 6 As shown, the ash receiving device 3 also includes a cover plate 37, which covers the ash removal port 36.

[0122] It should be understood that the cover plate 37 can be a flat plate structure that is adapted to the shape of the dust removal port 36, and its size is slightly larger than that of the dust removal port 36 so as to completely cover the dust removal port 36 and ensure good sealing.

[0123] It should be understood that the edges of the cover plate 37 are usually specially treated, such as chamfering or grinding.

[0124] It should be understood that the cover plate 37 may also be equipped with a handle or a connection structure that facilitates opening and closing with tools.

[0125] In this embodiment, the main function of the cover plate 37 is to seal the ash removal port 36. During normal operation of the ash receiving device 3, i.e. when ash does not need to be discharged, the cover plate 37 tightly covers the ash removal port 36 to prevent ash in the ash hopper 33 from leaking out of the ash removal port 36, thus avoiding pollution to the surrounding environment. At the same time, it can also prevent external dust, impurities, etc. from entering the ash hopper 33, thus avoiding affecting the normal collection and subsequent processing of ash.

[0126] In this embodiment, the good sealing performance of the cover plate 37 can also maintain the stable air pressure inside the ash hopper 33, ensuring the normal operation of the ash cleaning equipment, such as ensuring that the micro-positive pressure environment created by nitrogen filling is not damaged.

[0127] Figure 7 This is a cross-sectional view of a dust removal device according to an embodiment of this application. Figure 7 As shown, the dust removal device 2 includes at least two connection points 21, which are evenly distributed along a first direction. The dust removal device 2 is connected to the transmission device 1 at at least two connection points 21. The first direction is perpendicular to the moving direction of the dust removal device 2 and parallel to the bottom of the heat treatment chamber 101.

[0128] It should be understood that the dust removal device 2 is provided with at least two connection points 21, which are evenly distributed in a direction perpendicular to the direction of movement of the dust removal device 2, which helps to make the dust removal device 2 more evenly stressed under the drive of the transmission device 1.

[0129] In the cross-sectional view of the dust removal device of this application embodiment, the connection points 21 are distributed in a direction perpendicular to the moving direction of the dust removal device 2, so that the driving force of the transmission device 1 acting on the dust removal device 2 is parallel to the moving direction of the dust removal device 2.

[0130] In this embodiment, the multiple connection points 21 may be unevenly distributed and need to be kept at a certain distance so that the force points of the dust removal device 2 are distributed in a dispersed manner.

[0131] It should be understood that, due to the sealing requirements of the heat treatment chamber 101, the number of connection points 21 should not be too many, and can be 2-4.

[0132] In this embodiment, the transmission device 1 is connected to at least two connection points 21 of the cleaning device 2. When the transmission device 1 applies a driving force to the cleaning device 2, each connection point 21 can share the force collaboratively, preventing the cleaning device 2 from tilting, jamming, or deforming due to excessive local force. This ensures that the cleaning device 2 maintains a good fit with the bottom of the heat treatment chamber 101 during movement. Whether in the start-up, acceleration, deceleration, or constant speed movement phase, the cleaning device 2 will not easily shake or deviate from the predetermined movement path, which helps maintain the accuracy and continuity of the cleaning action and achieves stable and efficient cleaning operation.

[0133] Figure 8 This is another cross-sectional view of the dust removal device according to an embodiment of this application. Figure 8 As shown, the transmission device 1 includes a motor 11 and a connecting rope 12. The motor 11 is located outside the combustion heat treatment equipment 10. The motor 11 includes a drive shaft 110. One end of the connecting rope 12 is wound around the drive shaft 110, and the other end of the connecting rope 12 is connected to the ash cleaning device 2. The drive shaft 110 drives the ash cleaning device 2 to move toward the drive shaft 110 by rotation.

[0134] In this embodiment of the application, in the dust removal equipment of the combustion heat treatment equipment 10, the motor 11 is usually selected as a motor with high temperature resistance and high torque characteristics, such as an asynchronous motor.

[0135] It should be understood that if the speed and position control accuracy of the dust removal device 2 is required to be high, a DC motor can be selected, which has good speed regulation performance and starting torque.

[0136] In this embodiment, the drive shaft 110 is a power transmission component, and its rotational power comes from the motor 11. The drive shaft 110 needs to have high strength and rigidity to withstand the tension and torque transmitted by the connecting rope 12. It is usually made of high-quality carbon steel or alloy steel.

[0137] It should be understood that the connecting rope 12 can be wound around the drive shaft 110, that is, the connecting rope 12 is attached to the surface of the drive shaft 110 in a spiral shape. This winding method allows the connecting rope 12 to be wound or released in an orderly manner on the surface of the drive shaft 110 when the drive shaft 110 rotates, thereby driving the dust removal device 2 to achieve corresponding movement.

[0138] In this embodiment, the motor 11 may also include a spindle bracket, which is usually mounted on the housing of the motor 11 and located near the drive shaft 110. Its shape and structure may vary depending on the specific type and size of the motor 11 and the layout of the drive shaft 110.

[0139] In this embodiment, the spindle bracket can be fixed to the housing of the motor 11 by welding or bolting, and provides support for the drive shaft 110 from the side or bottom.

[0140] It should be understood that the connecting rope 12 needs to have sufficient strength and wear resistance to withstand the tension on the ash removal device 2 during movement and the friction with the bottom of the heat treatment chamber 101 and the furnace ash.

[0141] In this embodiment of the application, for example, the material of the connecting rope 12 may include high-strength steel wire rope or high-temperature resistant synthetic fiber rope, etc.

[0142] In this embodiment, the diameter of the connecting rope 12 and the size of the dust removal device 2 need to match each other to ensure the structural coordination of the entire dust removal equipment.

[0143] In this embodiment of the application, the connecting rope 12 needs to bear the weight of the dust removal device 2 and the resistance that may be encountered during the movement. The connecting rope 12 needs to have sufficient strength so that it will not break or cause other failures during the movement of the dust removal device 2.

[0144] It should be understood that, for example, the connecting rope 12 with a diameter of 6mm-10mm has relatively high tensile strength, which can meet the requirements of bearing the dust removal device 2 and overcoming resistance.

[0145] In this embodiment, the rotational speed of the drive shaft 110 is controlled by the motor 11. The rotation of the drive shaft 110 drives the cleaning device 2 to move toward the drive shaft 110, thereby controlling the movement speed of the cleaning device 2. For example, when it is necessary to speed up the cleaning speed of the cleaning device 2, the rotational speed of the motor 11 can be increased, causing the drive shaft 110 to rotate rapidly and the connecting rope 12 to wind up faster, thus allowing the cleaning device 2 to move toward the drive shaft 110 at a faster speed.

[0146] Figure 9 This is another cross-sectional view of the dust removal device according to an embodiment of this application. Figure 9 As shown, the motor 11 includes a first motor 111 and a second motor 112, and the connecting rope 12 includes a first connecting rope 121 and a second connecting rope 122. The first motor 111 and the second motor 112 are located on both sides of the combustion heat treatment equipment 10 along a second direction. The first motor 111 is connected to the ash removal device 2 through the first connecting rope 121, and the second motor 112 is connected to the ash removal device 2 through the second connecting rope 122. The first motor 111 and the second motor 112 drive the ash removal device 2 to move in the opposite direction of the second direction; wherein, the second direction is the direction of movement of the ash removal device 2.

[0147] It should be understood that the first motor 111 and the second motor 112 serve as the power source for the entire transmission device 1, and their types, performance parameters, etc., may be selected according to actual dust removal requirements.

[0148] In this embodiment of the application, for example, the type and performance parameters of the first motor 111 and the second motor 112 can be the same.

[0149] It should be understood that, for ease of description, the direction of movement of the cleaning device 2 is defined as the second direction, which is parallel to the bottom of the heat treatment chamber 101 and perpendicular to the height direction of the heat treatment chamber 101.

[0150] In this embodiment, during operation, the first motor 111 applies a pulling force to the cleaning device 2 via the first connecting rope 121, causing it to move along the second direction; when the cleaning device 2 moves to the drive shaft 110 of the first motor 111, the second motor 112 applies a pulling force in the opposite direction to the cleaning device 2 via the second connecting rope 122, causing it to move in the opposite direction of the second direction; when the cleaning device 2 moves to the drive shaft 110 of the second motor 112, the first motor 111 continues to apply a pulling force, causing the cleaning device 2 to reciprocate within the heat treatment chamber 101.

[0151] It should be understood that during operation, the first motor 111 and the second motor 112 rotate simultaneously in opposite directions. For example, when the dust removal device 2 needs to move from one end to the other for dust removal, the first motor 111 starts and rotates in the forward direction, pulling the dust removal device 2 through the first connecting rope 121, while the second motor 112 rotates in the reverse direction, appropriately loosening the second connecting rope 122, which, in conjunction with the drive of the first motor 111, causes the dust removal device 2 to move. When the dust removal device 2 needs to move in a certain direction, the rotation directions of the two motors are reversed accordingly, realizing the reverse movement of the dust removal device 2.

[0152] It should be understood that the first connecting rope 121 and the second connecting rope 122 only represent connecting ropes that pull the dust removal device 2 in opposite directions, and do not limit the number in each direction. For example, the positive direction of the second direction can be moved by pulling the dust removal device 2 with two first connecting ropes 121, and the opposite direction of the second direction can be moved by pulling the dust removal device 2 with two second connecting ropes 122.

[0153] In this embodiment, by using a first motor 111 and a second motor 112 installed in the combustion heat treatment equipment 10, the first motor 111 and the second motor 112 can drive the ash cleaning device 2 to reciprocate through the scaling of the first connecting rope 121 and the second connecting rope 122. This repeatedly cleans the ash at different locations, avoiding the dead spots that may exist in a single unidirectional movement, and greatly improving the comprehensiveness and thoroughness of ash cleaning. Compared with ash cleaning methods that can only move in one direction, reciprocating motion can complete the efficient cleaning of the entire bottom of the chamber in a shorter time, improving ash cleaning efficiency, better maintaining the clean environment inside the chamber, and ensuring the normal operation of the combustion heat treatment equipment 10 and the quality of material heat treatment.

[0154] Figure 10 This is another cross-sectional view of the dust removal device according to an embodiment of this application. Figure 10 As shown, the transmission device 1 also includes a drum 13, which is fixed to the drive shaft 110. The connecting rope 12 is wound around the drum 13, and the drum 13 drives the dust removal device 2 to move by rotating.

[0155] It should be understood that the roller 13 can be fixed on the drive shaft 110, that is, the roller 13 and the drive shaft 110 will not move relative to each other, so that the rotational motion of the drive shaft 110 can be stably transmitted to the roller 13.

[0156] It should be understood that the connecting rope 12 can be wound around the drum 13, that is, the connecting rope 12 is attached to the surface of the drum 13 in a spiral shape. This winding method allows the connecting rope 2 to be wound or released in an orderly manner on the surface of the drum 13 when the drum 13 rotates, thereby driving the dust removal device 2 to move accordingly.

[0157] In this embodiment, when the drive shaft 110 starts to rotate under the action of power, the roller 13 fixed to it also rotates. As the roller 13 rotates, the connecting rope 12 wound around it will gradually be wound onto the roller 13 or released from the roller 13.

[0158] In this embodiment, a driving method using a roller 13 and a connecting rope 12 is employed, resulting in a relatively simple and compact structure that occupies less space. Within the limited space of the combustion-type heat treatment equipment 10, this structural design of the transmission device 1 allows for better layout and installation.

[0159] In this embodiment, the roller 13 rotates to drive the connecting rope 12, thereby pulling the cleaning device 2 to move. This driving method is more stable. Compared with directly pulling the connecting rope 12 with the drive shaft 110, it can effectively reduce the swaying and shaking of the connecting rope 12, making the cleaning device 2 move more smoothly and improving the uniformity and thoroughness of cleaning. At the same time, it can also reduce the wear of the drive shaft 110, protect the transmission device 1, and reduce the possibility of failure.

[0160] In this embodiment of the application, the transmission device 1 further includes a reducer 14, which is connected to the drive shaft 110 and is used to control the rotational speed of the drive shaft 110.

[0161] It should be understood that the reducer 14 can be a mechanical transmission device, which can be composed of multiple gears, shafts, housings, and lubrication and sealing devices. The type of reducer 14 can include cylindrical gear reducers, bevel gear reducers, worm gear reducers, etc.

[0162] In this embodiment, the reducer 14 can be connected to the drive shaft 110 via a coupling. The coupling serves to transmit torque, compensate for installation errors, and buffer vibrations.

[0163] In this embodiment of the application, the reducer 14 is connected to the drive shaft 110 to control the rotational speed of the drive shaft 110.

[0164] In this embodiment, in the dust removal equipment of the combustion heat treatment equipment 10, the excessively high speed of the motor 11 causes the dust removal device 2 to move too fast, which may reduce the dust removal effect of the dust removal device 2, and may even cause shaking or instability. The reducer 14, through its internal gear transmission ratio or worm gear transmission ratio, reduces the high speed output of the motor 11 to a suitable speed value and transmits it to the drive shaft 110, thereby enabling the dust removal device 2 to move at a stable speed that meets the requirements of the dust removal effect.

[0165] In this embodiment, the speed of the drive shaft 110 is controlled by the reducer 14, so that the dust removal device 2 can move at a suitable speed. The stable and appropriate moving speed avoids the situation where the dust removal area is missed due to excessive speed or the dust removal efficiency is affected due to excessive speed, thereby improving the quality and effect of dust removal.

[0166] Figure 11 This is another cross-sectional view of the dust removal device according to an embodiment of this application. Figure 11 The cleaning device 2 extends along a first direction, and the ratio of the dimension of the cleaning device 2 along the first direction to the dimension of the heat treatment chamber 101 along the first direction is greater than or equal to 2 / 3 and less than 1; wherein, the first direction is perpendicular to the moving direction of the cleaning device 2 and parallel to the bottom of the heat treatment chamber 101.

[0167] In this embodiment, the ratio of the dimension h of the cleaning device 2 along the first direction to the dimension H of the heat treatment chamber 101 along the first direction is greater than or equal to 2 / 3, which allows the cleaning device 2 to cover most of the bottom area of ​​the chamber in a direction perpendicular to its movement.

[0168] It should be understood that a larger size ratio allows the cleaning device 2 to clean a wider area in one movement, reducing cleaning dead corners, improving the comprehensiveness and efficiency of cleaning, and avoiding the need for multiple round trips to cover the entire area due to the small size of the cleaning device 2, thereby saving cleaning time and energy consumption.

[0169] In this embodiment, the dust removal device 2 cannot be completely equal to the size of the chamber along the first direction. A certain amount of space needs to be reserved for the movement of the dust removal device 2 to prevent it from interfering with the chamber wall at the bottom of the chamber due to its excessive size, thus preventing it from moving smoothly. Therefore, the ratio is less than 1.

[0170] It should be understood that in order to adapt to different chamber structures and internal layouts, if the size of the dust removal device 2 is exactly the same as the size of the chamber, there may be many inconveniences in the actual installation, debugging and subsequent possible maintenance process. Therefore, the ratio is less than 1.

[0171] In this embodiment, by adjusting the ratio of the dimension of the ash removal device 2 along the first direction to the dimension of the heat treatment chamber 101 along the first direction, it can more evenly clean the furnace ash across the entire width range during movement. This avoids incomplete or excessive cleaning in certain areas, resulting in more uniform cleaning of the furnace ash at the bottom of the heat treatment chamber 101. This helps maintain a good heat transfer environment within the chamber and ensures the stability of the material's heat treatment quality.

[0172] In this embodiment of the application, the material of the dust removal device 2 includes high-temperature resistant metal materials.

[0173] It should be understood that the heat treatment chamber 101 of the combustion heat treatment equipment 10 often operates at a high temperature, and furnace ash accumulates at the bottom of the heat treatment chamber 101 under such a high-temperature environment. The ash removal device 2 needs to be in contact with the ash for a long time and perform ash removal operations, so it must be made of high-temperature resistant metal materials to ensure its own structural performance is stable and will not soften, deform, or melt due to high temperatures, so as to continuously and effectively complete the ash removal task.

[0174] In this embodiment, the material of the dust removal device 2 may include stainless steel, such as 310S stainless steel, which contains high levels of chromium (Cr) and nickel (Ni) elements, exhibiting excellent high-temperature resistance and maintaining good strength and oxidation resistance in high-temperature environments of approximately 900℃-1150℃. The dense chromium oxide film formed on its surface can effectively resist high-temperature oxidation, and stainless steel has good processing properties, making it easy to manufacture into various shapes required for the dust removal device 2.

[0175] In this embodiment, the material of the cleaning device 2 may also include heat-resistant steel, such as chromium-molybdenum alloy steel. This type of heat-resistant steel, through the addition of alloying elements, possesses good high-temperature strength, creep resistance, and oxidation resistance, and can withstand high temperatures of approximately 550℃-650℃. The cleaning device 2 made using this type of heat-resistant steel can provide sufficient structural support while meeting high-temperature requirements.

[0176] In this embodiment, the material of the dust removal device 2 may also include a high-temperature alloy, such as a nickel-based high-temperature alloy. This alloy uses nickel as a base and incorporates various other elements such as chromium, molybdenum, and titanium, exhibiting excellent high-temperature resistance and capable of operating normally at temperatures of 650-1200℃ or even higher. It also possesses good resistance to thermal corrosion and fatigue. Using a nickel-based high-temperature alloy to manufacture the dust removal device 2 ensures its reliable operation.
