[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0022] This application provides a dust removal device, including a pipeline, a first dust removal unit, a second dust removal unit, and a filter unit. The pipeline is connected to an oven and includes a first section and a second section, which are sequentially connected along the gas conveying direction. The first dust removal unit includes a first dust removal cylinder, which is connected to the first section and removes dust from the gas flowing through the first section before discharging it into the environment. The second dust removal unit includes a second dust removal cylinder, which is connected to the second section and performs preliminary dust removal on the gas in the second section. The filter unit includes an air inlet assembly, a housing, a partition plate, a filter cartridge, and an exhaust assembly. The partition plate is disposed inside the housing and divides the housing into a first cavity and a second cavity. The two ends of the air inlet assembly are respectively connected to the second dust removal cylinder and the first cavity, and the air inlet assembly is used to convey the pre-dust-removed gas into the first cavity. The filter cartridge is detachably installed on the isolation plate. The filter cartridge connects the first chamber and the second chamber. The filter cartridge is used to filter the gas in the first chamber. The filtered gas enters the second chamber. The second chamber delivers the filtered gas to the exhaust assembly. The exhaust assembly discharges the gas flowing through it into the environment.

[0023] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0024] like Figure 1-3As shown, an exemplary embodiment of this application provides a dust removal device for segmented processing of gas inside an oven. The dust removal device includes a pipeline 1, a first dust removal unit 2, a second dust removal unit 3, and a filter unit 4. The pipeline 1 is connected to the oven and includes a first section 11 and a second section 12. The first section 11 and the second section 12 are connected sequentially along the gas conveying direction. In one example, the first section 11 is connected to the front section of the oven and is used to convey the gas at the front end of the oven. The second section 12 is connected to the middle and rear sections of the oven and is used to convey the gas in the middle and rear sections of the oven. The first section 11 and the second section 12 can be connected to the oven via flanges. The first dust removal unit 2 includes a first dust removal cylinder 21, which is connected to the first section 11. The first dust removal cylinder 21 removes dust from the gas flowing through the first section 11 and then discharges it into the environment. The first dust removal cylinder 21 is cylindrical in shape. After the gas enters, the dust contained in the gas settles to the bottom of the first dust removal cylinder 21, and the settled gas is discharged into the environment. The second dust removal unit 3 includes a second dust removal cylinder 31, which is connected to the second part 12 and performs preliminary dust removal on the gas in the second part 12. The second dust removal cylinder 31 is cylindrical in shape. After the gas enters, the dust contained in the gas settles to the bottom of the second dust removal cylinder 31, and the settled gas is discharged into the filter unit 4 for further filtration. The filter unit 4 includes an air inlet assembly 41, a housing 42, an isolation plate 43, a filter cartridge 44, and an exhaust assembly 45. The isolation plate 43 is fixedly installed inside the housing 42, and the fixing method can be bolted or welded. The isolation plate 43 divides the housing 42 into a first cavity 46 and a second cavity 47. One end of the air inlet assembly 41 is connected to the second dust removal cylinder 31, and the other end is connected to the first cavity 46, delivering the pre-dust-removed gas to the first cavity 46. The filter cartridge 44 is detachably installed on the isolation plate 43, wherein the filter cartridge 44 can be snapped onto the isolation plate 43 or bolted onto the isolation plate 43. The filter cartridge 44 is located inside the first chamber 46 and is connected to both the first chamber 46 and the second chamber 47. Gas in the first chamber 46 passes through the filter cartridge 44, leaving dust inside. The filtered gas then enters the second chamber 47. In some examples, the isolation plate 43 has multiple mounting holes, and the interior of the filter cartridge 44 communicates with these holes, allowing the filtered gas to enter the second chamber 47. The second chamber 47 is used to transport the filtered gas, and the exhaust assembly 45 is connected to the second chamber 47 to exhaust the gas from it. In one example, the isolation plate 43 is vertically oriented, with the first chamber 46 and the second chamber 47 located on the left and right sides of the isolation plate 43, respectively. The filtered gas enters the second chamber 47 and is then exhausted through the exhaust assembly 45.

[0025] In this embodiment, pipeline 1 is divided into a first part 11 and a second part 12 connected sequentially and connected to the oven, which can realize the diversion and transportation of gas, allowing gases with different dust-containing states to enter the corresponding processing paths, adapting to the complex working conditions of the oven exhaust gas, and implementing different processing methods for gases at different stages. The first dust removal cylinder 21 of the first dust removal unit 2 is connected to the first part 11 of pipeline 1, and can directly remove dust from the gas in a specific path before discharge, which can quickly process gases with low dust content, reduce the load on the subsequent filter unit 4, reduce energy consumption, and improve processing efficiency. The second dust removal cylinder 31 of the second dust removal unit 3 is connected to the second part 12 of pipeline 1, and performs preliminary dust removal on the gas, which can remove larger dust particles in advance, prevent them from directly entering the filter unit 4 and causing blockage, extend the service life of the filter cartridge 44, and reduce the maintenance frequency. In the filter unit 4, the isolation plate 43 divides the housing 42 into a first chamber 46 and a second chamber 47, which can effectively isolate unfiltered gas from filtered gas and prevent secondary pollution; the detachable filter cartridge 44 is convenient for regular replacement and cleaning to ensure the filtration effect; the air inlet assembly 41 can stably deliver the gas after preliminary dust removal to the first chamber 46 to ensure filtration uniformity; the exhaust assembly 45 provides power for gas flow to ensure that the filtered clean gas meets the emission standards.

[0026] In an exemplary embodiment, the first dust removal unit 2 further includes a first support frame and a first dust collection bin. The first support frame can be made of high-strength metal, such as welded from angle steel or square tubing, providing a stable support foundation. A first dust collection cylinder 21 is mounted on the first support frame, either by welding or by screwing. The first dust collection bin is detachably mounted at the bottom of the first dust collection cylinder 21. Detachment can be achieved by bolting or snap-fitting the first dust collection bin to the bottom of the first dust collection cylinder 21. A rubber sealing ring can be provided between the first dust collection cylinder 21 and the first dust collection bin to prevent dust leakage during settling. The first dust collection bin can be made of plastic or metal, and a dust collection bag can be installed inside the first dust collection bin, which can be replaced directly when cleaning is required.

[0027] In this embodiment, the first support frame provides a stable installation foundation for the first dust collector 21, which can effectively prevent it from shaking or shifting during gas flow or equipment operation. At the same time, the support structure can be adjusted to adapt to different on-site installation environments, ensuring that the first dust collector 21 is always in a stable working state. The detachable first dust collection bin is convenient for operators to quickly remove for centralized cleaning or recycling of the collected dust, and can reduce the risk of secondary dust re-entrainment during the cleaning process. Furthermore, the connection between the bin and the bottom of the first dust collector 21 can be sealed to prevent dust leakage, further improving the structural stability, ease of operation, and reliability of the dust removal unit 2.

[0028] In one exemplary embodiment, casters are provided at the bottom of the first support frame to facilitate its movement. The casters are made of high-strength, wear-resistant materials, such as polyurethane or rubber, enabling them to adapt to complex ground conditions. The casters are evenly distributed at the corners of the bottom of the first support frame, ensuring balanced support without compromising overall stability. Simultaneously, the casters are equipped with braking devices, such as foot brakes, which can be locked after the first support frame has moved to the target position to prevent accidental slippage and ensure the stability of the first dust collection cylinder 21.

[0029] In this embodiment, casters are provided at the bottom of the first support frame, significantly improving the mobility of the first dust removal unit 2. During equipment installation, the docking position between the first dust removal cylinder 21 and the first part 11 of the pipeline 1 can be easily adjusted without relying on large handling tools, reducing installation difficulty. During routine maintenance, the equipment can be conveniently moved to an area with more operating space, facilitating the inspection of the first dust removal cylinder 21 or the cleaning of the first dust collection bin, reducing the intensity of manual handling. The casters ensure both ease of movement and operational stability of the first dust removal unit 2, further enhancing the site adaptability and operational practicality of the entire dust removal device.

[0030] In an exemplary embodiment, the bottom of the first dust collector 21 has a tapering conical structure, causing the bottom of the first dust collector 21 to gradually narrow from the body to the end, forming a funnel-like shape. The bottom of the second dust collector 31 also has a conical structure, causing the bottom of the second dust collector 31 to gradually narrow from the body to the end, forming a funnel-like shape. This structure causes the airflow to form a downward swirling or guiding effect along the conical wall when the gas flows inside the cylinder, carrying dust to the bottom; at the same time, the tapering space can accelerate the dust settling process and prevent the dust from being re-entrained in the rising airflow.

[0031] In this embodiment, the conical structure, by tilting, prevents dust from gathering at the bottom. The combined effect of gravity and airflow guidance accelerates dust settling, reducing dust retention or re-entrainment by the airflow and improving dust removal efficiency. Simultaneously, the conical structure's contraction characteristic makes it easier for dust to concentrate and fall into the dust collection chamber at the bottom, preventing dust accumulation on the cylinder walls and reducing cleaning difficulty.

[0032] In one exemplary embodiment, the first dust removal unit 2 further includes a first air inlet duct and a first air outlet duct. One end of the first air inlet duct is connected to the first part 11, and the other end is connected to the first dust removal cylinder 21. It is used to transport the gas from the first part 11 to the first dust removal cylinder 21. When the gas enters the first dust removal cylinder 21, it enters tangentially along the inner wall of the first dust removal cylinder 21, so that a spiral rotating airflow is formed inside the cylinder after the gas enters. Centrifugal force is used to throw the dust in the gas towards the cylinder wall, thereby separating the dust and gas. In one example, a through hole is formed in the upper part of the side wall of the first dust removal cylinder 21, and the first air inlet duct is connected to the through hole, through which gas is transported into the first dust removal cylinder 21. One end of the first exhaust duct passes through the top of the first dust collector 21 and extends into the cylinder. In one example, a through hole is opened in the middle of the top of the first dust collector 21. The first exhaust duct extends into the first dust collector 21 through the through hole, and the height of the end of the first duct that extends into the first dust collector 21 is lower than the position where the first air inlet duct connects with the first dust collector 21. This prevents gas that has not been fully separated from directly entering the exhaust duct, ensuring that the gas undergoes a complete spiral separation process in the cylinder. Finally, the gas after dust removal is discharged through the first exhaust duct.

[0033] In this embodiment, the first air inlet duct guides the gas to enter along the tangential direction of the inner wall of the first dust removal cylinder 21 and forms a spiral rotating airflow. It can use centrifugal force to throw the dust in the gas toward the cylinder wall, realize the rapid separation of gas and dust, and improve the dust removal efficiency of the first dust removal unit 2. The first exhaust duct runs through the top of the first dust removal cylinder 21 and the end extending into the cylinder is lower than the air inlet connection. This can prevent the dust-laden gas that has not been fully separated from directly entering the first exhaust duct, ensuring that the gas completes the complete spiral separation process in the cylinder and ensuring the cleanliness of the exhaust gas. At the same time, this structural design does not require complex filter components, reducing the risk of filter material clogging and maintenance costs, and further improving the operational stability of the first dust removal unit 2.

[0034] In one exemplary embodiment, the second dust removal unit 3 further includes a second air inlet duct 32 and a second air outlet duct 33. One end of the second air inlet duct 32 is connected to the second part 12, and the other end is connected to the second dust removal cylinder 31. It is used to transport the gas from the second part 12 to the second dust removal cylinder 31. When the gas enters the second dust removal cylinder 31, it enters tangentially along the inner wall of the second dust removal cylinder 31, so that a spiral rotating airflow is formed inside the cylinder after the gas enters the second dust removal cylinder 31. Centrifugal force is used to throw the dust in the gas towards the cylinder wall, thereby separating the dust and gas. In one example, a through hole is opened in the upper part of the side wall of the second dust removal cylinder 31, and the second air inlet duct 32 is connected to the through hole, through which gas is transported into the second dust removal cylinder 31. One end of the second exhaust duct 33 passes through the top of the second dust collector 31 and extends into the cylinder. In one example, an opening is provided in the middle of the top of the second dust collector 31. The second exhaust duct 33 extends into the second dust collector 31 through this opening. The height of the end of the second exhaust duct 33 extending into the second dust collector 31 is lower than the position where the second air inlet duct 32 connects with the second dust collector 31, so as to form a middle partition air chamber. This prevents gas that has not been fully separated from directly entering the second exhaust duct 33, ensuring that the gas undergoes a complete spiral separation process in the cylinder. Finally, the gas after dust removal is discharged through the second exhaust duct 33.

[0035] In this embodiment, the second air inlet duct 32 guides the gas to enter along the tangential direction of the inner wall of the second dust removal cylinder 31 and forms a spiral rotating airflow. It can use centrifugal force to throw the dust in the gas toward the cylinder wall, realize the rapid separation of gas and dust, and improve the dust removal efficiency of the second dust removal unit 3. The second exhaust duct 33 runs through the top of the second dust removal cylinder 31 and extends into the cylinder at a height lower than the air inlet connection. This can prevent the dust-laden gas that has not been fully separated from directly entering the second exhaust duct 33, ensuring that the gas completes a complete spiral separation process in the cylinder and ensuring the cleanliness of the discharged gas. At the same time, this structural design does not require complex filter components, reduces the risk of filter material clogging and maintenance costs, and further improves the operational stability of the second dust removal unit 3.

[0036] In one exemplary embodiment, the filter unit 4 further includes a second dust collection chamber, which is detachably disposed at the bottom of the housing 42. The second dust collection chamber receives dust collected during the filtration process. In the first example, the second dust collection chamber can be connected to the housing 42 by clips or bolts, facilitating quick installation and disassembly by the operator. A sealing strip is provided between the second dust collection chamber and the housing 42 to prevent dust leakage from gaps and ensure dust collection efficiency. During the filtration process, dust in the gas is intercepted by the filter cartridge 44 and gradually settles to the bottom of the housing 42 due to gravity, then falls into the connected second dust collection chamber, achieving centralized dust collection. When the dust in the second dust collection chamber accumulates to a certain amount, the operator can directly remove it for cleaning or recycling without large-scale disassembly of the entire filter unit 4, greatly simplifying the maintenance process.

[0037] In this embodiment, the second dust collection chamber of the filter unit 4 is connected to the bottom of the housing 42 and is detachably installed. This not only efficiently collects the dust that settles during the filtration process, preventing dust from accumulating inside the housing 42 and affecting the filtration effect, but also, due to its detachable nature, allows operators to quickly and regularly disassemble, clean, or recycle the dust, simplifying maintenance operations and reducing equipment downtime. At the same time, the sealing design at the connection prevents dust leakage, ensuring the working reliability of the filter unit 4 and improving the convenience of maintenance and the stability of operation of the entire dust removal device.

[0038] In one exemplary embodiment, multiple filter cartridges 44 are provided, and the multiple filter cartridges 44 are evenly arranged inside the housing 42, while the extending direction of the filter cartridges 44 is parallel to the side wall of the housing 42. The filter cartridges 44 can be distributed on the isolation plate 43 in a matrix or at equal intervals to ensure that there is sufficient space around each filter cartridge 44 for gas flow; the extending direction of the filter cartridges 44 parallel to the side wall of the housing 42 allows them to better adapt to the internal space of the housing 42, especially in housings 42 with regular shapes such as cuboids, which can maximize the use of longitudinal space and reduce the lateral space occupied by the filter cartridges 44. This design allows the gas delivered into the first chamber 46 via the air inlet assembly 41 to be more evenly distributed to each filter cartridge 44, preventing some filter cartridges 44 from being overloaded due to concentrated airflow. At the same time, the synergistic effect of multiple filter cartridges 44 can significantly increase the filtration area and improve the gas throughput per unit time. Furthermore, the extension direction parallel to the side wall facilitates the installation, disassembly, and replacement of the filter cartridges 44, and operators can easily complete maintenance operations along the axial direction of the filter cartridges 44.

[0039] In this embodiment, multiple filter cartridges 44 are evenly arranged inside the housing 42 and extend in a direction parallel to the side wall of the housing 42. This not only significantly improves the gas treatment efficiency and purification capacity of the filter unit 4 by increasing the filtration area, but also allows the gas to be evenly distributed to each filter cartridge 44 in the first cavity 46, avoiding excessive load on some filter cartridges 44 and shortening their service life. At the same time, the extension direction parallel to the side wall makes full use of the space in the housing 42 and facilitates the installation, disassembly and maintenance of the filter cartridges 44, reducing the difficulty of operation and improving the overall operational stability, working efficiency and maintenance convenience of the filter unit 4.

[0040] In an exemplary embodiment, the exhaust assembly 45 includes a first pipe, a second pipe, and a fan. One end of the first pipe is connected to a second cavity 47, and the other end is connected to the fan. One end of the second pipe is connected to one end of the first pipe. The fan discharges the filtered gas through the first and second pipes. The fan, acting as a power source, creates negative pressure within the first pipe through its own suction, thereby drawing the clean gas filtered by the filter cartridge 44 into the first pipe. One end of the second pipe is connected to the first pipe, and the other end is used to connect to the external environment, preventing the discharged gas from affecting the workshop operating area. Valves can be installed on the first and second pipes to facilitate cutting off the airflow when the fan is under maintenance, or to adjust the exhaust volume according to actual operating conditions, ensuring that the exhaust assembly 45 can stably deliver clean gas and adapt to different on-site usage scenarios.

[0041] In this embodiment, the fan provides stable power and can extract filtered clean gas, preventing the clean gas from accumulating in the second cavity 47 and affecting the gas flow efficiency of the filter unit 4.

[0042] In one exemplary embodiment, a temperature sensor is also included. Multiple temperature sensors may be provided and respectively located at the inlet of the first dust collector 21 and the inlet of the second dust collector 31. The temperature sensor is used to detect the temperature of the gas entering the first dust collector 21 and the second dust collector 31. When the temperature is higher than the preset temperature, the equipment is cooled down in time to avoid damage to the equipment due to high temperature.

[0043] In this embodiment, the temperature sensor allows operators to promptly monitor gas temperature changes. If an abnormal temperature is detected, appropriate measures can be taken quickly to prevent damage to the equipment and ensure its safety and stability.
