At the same time, precious metal powder mixed in with the material is carried by the wind and is not easy to be recycled. Therefore, there is an urgent need for a dust adsorption device for the discharge of photovoltaic panel pyrolysis furnaces to reduce dust pollution to the working environment and improve the recycling rate of precious metals. Utility Model Content

[0003] This invention proposes a dust adsorption device for photovoltaic panel pyrolysis furnace discharge, which solves the problems of dust pollution in the working environment during photovoltaic panel pyrolysis furnace discharge, precious metal powder being scattered with the dust, and low recycling rate.

The base plate has a sedimentation chamber and a filter chamber. The sedimentation chamber is a hollow cavity with a funnel-shaped bottom and an opening at the bottom. The sedimentation chamber has an inlet pipe A and an outlet pipe B on its front and rear sides. The inlet pipe A is connected to a dust cover via a pipe. The dust cover is fixed next to the discharge port of the photovoltaic panel pyrolysis furnace. The bottom of the sedimentation chamber has a dust removal box A. The outlet pipe B is connected to two filter chambers via pipes. The filter chamber contains a filter cartridge. One side of the filter chamber has an outlet pipe C, which is connected to a negative pressure device via a pipe.

[0005] Preferably, the sedimentation chamber has several inclined guide plates inside, and the top and bottom of the inclined guide plates are 30mm-50mm away from the inner wall of the sedimentation chamber.

[0006] Preferably, the filter chamber consists of a lower cover, an upper cover, a dust collection chamber, a filter cartridge support A, a filter cartridge support B, a filter cartridge, an air outlet pipe C, and a dust removal box B. The lower cover and the upper cover are rotatably connected. The bottom of the lower cover has a dust collection chamber, and one side of the dust collection chamber has a dust removal box B. The inner walls of the lower cover have filter cartridge supports A and B on both sides. The two ends of the filter cartridge are snapped into filter cartridge supports A and B. The outlet of the clean air chamber of the filter cartridge is snapped into the air outlet pipe C.

[0007] Preferably, one end of the filter cartridge is closed, and the closed part is concave to form a groove. The groove is engaged with the filter cartridge support B. The other end of the filter cartridge has a snap-fit, the inner side of which is engaged with the filter cartridge support A. The snap-fit ​​is engaged with the air outlet pipe C, and a sealing strip is provided at the snap-fit ​​point.

[0008] Preferably, the top cover has a handle on its outer edge and an observation window on its top.

[0009] Preferably, the base plate is made of 3mm patterned steel plate, and the base plate has casters at the four corners.

[0010] Preferably, the ash removal box A has a handle on its outer edge, and the ash removal box A has limit strips on both sides.

[0012] Preferably, the sedimentation tank, lower cover, and upper cover are made of stainless steel sheet.

[0013] Preferably, the negative pressure device is a negative pressure fan.

[0014] The principle of this invention: This invention uses a combination of a sedimentation chamber and a filter chamber to absorb and filter the dust and precious metal powder mixed in the dust generated during the discharge of the photovoltaic panel pyrolysis furnace. The sedimentation chamber is a hollow box structure with an inlet pipe A and an outlet pipe B on both sides. The inlet pipe A is used to connect to the dust cover. Under the action of a negative pressure fan, the dust is sucked into the sedimentation chamber. Larger dust particles and heavier precious metal powder move downwards under the action of gravity, passing through the funnel-shaped opening at the bottom of the sedimentation chamber and falling into the dust removal box A. Operators can periodically clean the dust removal box A to recover the precious metal powder. The sedimentation chamber contains several inclined guide plates, which are fixed at an angle to the front and rear inner walls of the sedimentation chamber. The top and bottom of the guide plates are not connected to the upper and lower inner walls of the sedimentation chamber, but are separated by a distance. Under these conditions, the dust passes through multiple times... The inclined guide plate increases the residence time of dust particles in the sedimentation chamber, allowing more dust to fall into the dust removal box A under the influence of gravity, completing the first dust treatment process. Subsequent dust particles then follow the airflow into the filtration chamber. The filter cartridges within the filtration chamber are limited by filter cartridge supports A and B, using a snap-fit ​​design for easy replacement and cleaning. The clean air chamber outlet of the filter cartridge is connected to the exhaust pipe C, which in turn is connected to a negative pressure fan. Under these conditions, smaller dust particles and precious metal powders cannot pass through the pleated filter media and are blocked within the filtration chamber, finally falling into the dust removal box B below the dust collection chamber for easy cleaning and maintenance. There are two filtration chambers; users can disable one while maintaining the other, ensuring stable and reliable operation of the device and improving its utilization rate.

[0015] The beneficial effects of this utility model are as follows: A dust adsorption device for photovoltaic panel pyrolysis furnace discharge has a reasonable structural design, is easy to use, can be operated in a mobile manner, has strong adaptability, and has a good filtration effect. It can remove the dust generated when the photovoltaic panel pyrolysis furnace discharges, protect the working environment, protect the health of the workers, and improve the recycling rate of precious metals in photovoltaic panels.

The base plate 101 has the sedimentation chamber 200 and the filter chamber 300. The sedimentation chamber 200 is a hollow cavity with a funnel-shaped bottom and an opening at the bottom. The sedimentation chamber 200 has an air inlet pipe A201 and an air outlet pipe B202 on its front and rear sides. The air inlet pipe A201 is connected to a dust cover through a pipe. The dust cover is fixed next to the discharge port of the photovoltaic panel pyrolysis furnace. The sedimentation chamber 200 has a dust removal box A203 at its bottom. The air outlet pipe B202 is connected to two filter chambers 300 through a pipe. The filter chamber 300 contains a filter cartridge 306. The filter chamber 300 has an air outlet pipe C309 on one side, which is connected to a negative pressure device through a pipe. In this embodiment, the sedimentation chamber 200 performs preliminary dust filtration, mainly separating larger dust particles and precious metal powders under the action of gravity; the filter chamber 300, under the action of the folded filter media of the filter cartridge 306, filters smaller dust particles and precious metal powders, completing the deep dust filtration, reducing dust pollution to the working environment, preventing workers from inhaling dust, and protecting the health of workers.

[0023] Specifically, such as Figure 2 , Figure 3As shown, the sedimentation chamber 200 has several inclined guide plates 204 inside, and the top and bottom of the inclined guide plates 204 are 30mm-50mm away from the inner wall of the sedimentation chamber 200. In this embodiment, the inclined guide plates 204 are fixed at an angle to the front and rear inner walls of the sedimentation chamber 200, and the top and bottom are not connected to the upper and lower inner walls of the sedimentation chamber 200, but are at a distance. Under this condition, the dust passes through the inclined guide plates 204 multiple times, and the residence time in the sedimentation chamber 200 becomes longer. Under the action of gravity, more dust falls into the dust removal box A203.

[0024] Specifically, such as Figure 4 , Figure 5 As shown, the filter chamber 300 consists of a lower cover 301, an upper cover 302, a dust collection chamber 303, a filter cartridge support A304, a filter cartridge support B305, a filter cartridge 306, an air outlet pipe C309, and a dust removal box B310.

The latch 308 also engages with the air outlet pipe C309, and a sealing strip is provided at the engagement point. In this embodiment, when replacing the filter cartridge 306 using a manual replacement device, the filter cartridge support B305 needs to be pushed outward to remove the filter cartridge 306, preventing the filter cartridge 306 from detaching during use. Furthermore, disassembling and installing the filter cartridge 306 is convenient and easy, reducing maintenance costs.

[0026] Specifically, the upper cover 302 has a handle on its outer edge and an observation window on its top. In this embodiment, operators can check the status of the filter cartridge 306 through the observation window, perform timely cleaning and maintenance, and ensure the stable and reliable operation of the device.

[0027] Specifically, such as Figure 1 , Figure 2 As shown, the base plate 101 is made of 3mm patterned steel plate, and the base plate 101 has casters 102 at its four corners. In this embodiment, by adopting the above solution, the device can be used in a mobile manner, making its use more flexible.

[0028] Specifically, such as Figure 2 As shown, the ash removal box A203 has a handle on its outer edge, and limit strips 205 on both sides of the ash removal box A203. In this embodiment, the limit strips 205 limit the position of the ash removal box A203, making it convenient for operators to clean the ash removal box A203.

[0029] Specifically, there are two valves on the pipe connecting the air outlet pipe B202 to the two filter chambers 300. In this embodiment, the user can close the valves to disable any one filter chamber 300 and perform maintenance on the other filter chamber 300, ensuring stable and reliable operation of the device and improving the utilization rate of the device.

[0030] Specifically, the sedimentation tank 200, lower cover 301, and upper cover 302 are made of stainless steel. In this embodiment, the sedimentation tank 200, lower cover 301, and upper cover 302 made of stainless steel are corrosion-resistant and have a long service life.

[0031] Specifically, the negative pressure device is a negative pressure fan. In this embodiment, the negative pressure fan has a large suction power and low procurement cost. The negative pressure fan is connected to the air outlet pipe C309 through a pipeline to provide a negative pressure environment for the sedimentation chamber 200 and the filter chamber 300, absorb dust, and drive the operation of the entire device.
