[0032] Preferably, the filter element is detachably connected to the filter element mounting plate.

[0033] The pulse pipe is selected to have a "U" - shaped structure. Each side of the "U" - shaped corresponds to a filter element. Therefore, each pulse pipe can clean two filter elements. Its beneficial effects are as follows: it realizes the uniform distribution of the pulse wave in the pipe, thereby comprehensively and evenly cleaning the filter element, improving the cleaning effect and making the cleaning process more efficient; it makes the structure of the pulse pipe more compact and occupies less space, which is particularly important for applications with limited space; in addition, during the cleaning process, the "U" - shaped pulse pipe generates less noise, effectively reducing the noise generated by the operation of the machine.

[0065] A filtering device 300, located inside the main body of the recovery bin, at a position above the feed inlet 110, dividing the interior of the main body of the recovery bin into an upper space and a lower space;

[0066] An air jet dust cleaning device 200, located above the filtering device 300;

[0067] An opening 150 is provided in the upper space of the main body of the recovery bin. The opening 150 is located between the air jet dust cleaning device 200 and the filtering device 300. One end of a fan pipeline 480 is connected to the opening 150, and the other end is connected to a negative pressure suction device.

[0068] Specifically, when in use, when the powder enters the bin from the front feed inlet 110, most of the powder can go out through the discharge outlet 120 and be collected. Part of the powder is lifted up. At this time, the negative pressure suction device is turned on and connected through the fan pipeline 480, so that a negative pressure state is formed in the bin. The dust is carried upwards by the air flow. The air flow passes through the filtering device 300, and the dust is adsorbed by the filtering device 300. When the amount of dust adsorbed by the filtering device 300 reaches a certain amount, the air jet dust cleaning device 200 is turned on, and compressed air is instantaneously ejected to form a jet air flow. The amount of gas ejected is sufficient to spray the dust on the filtering device 300 to the discharge outlet and be collected, thus completing the dust cleaning process.

[0069] The device of the present utility model has a simple structure. It can not only effectively reduce the generation and diffusion of dust, ensure the cleanliness of the dust-free workshop, but also effectively recover the powder raw materials.

[0070] Specifically, the opening 150 on the side of the outer shell is on either the left or the right; the position of the opening allows the negative pressure suction device and the fan duct 480 to be installed according to the actual situation of the site.

[0071] On the basis of the above solution, further, the top of the outer shell 100 has a first inspection opening 130, which is connected to the upper space, and a second inspection opening 140, which is located above the jet dust cleaning device 200. The first inspection opening 130 is covered by a first top cover plate 131, and the second inspection opening 140 is covered by a second top cover plate 141. Handles 132 are provided on the first top cover plate 131 and the second top cover plate 141.

[0072] The function of the first inspection opening 130 is to facilitate timely operation to clear the blockage when the powder particles block the discharge port. The function of the second inspection opening 140 is to facilitate the maintenance of the pulse dust cleaning device. The first inspection opening 130 and the second inspection opening 140 are beneficial to the maintenance of the device during later use.

[0073] On the basis of the above solution, further, the outer shell 100 is made of plastic, and reinforcing ribs 160 are provided on the outside of the outer shell 100. The reinforcing ribs 160 provided on the outside of the outer shell 100 function to enhance the support force of the outer shell 100.

[0074] Preferably, the outer shell 100 is made of one of polypropylene, polystyrene or polyvinyl chloride.

[0075] More preferably, the outer shell 100 is made of polypropylene. The polypropylene material is a thermoplastic plastic with low price, light weight, chemical corrosion resistance and good heat resistance, which can effectively extend the service life of the device and reduce the manufacturing cost.

[0076] On the basis of the above solution, further, the inner space of the lower space of the main body of the recycling bin is covered with a lining plate, and the lining plate is made of a material that can withstand temperatures above 400°C and has a smooth surface.

[0077] On the basis of the above solution, further, the lining plate is made of a non-material that does not easily react chemically with the powder.

[0078] Preferably, the lining plate is made of polytetrafluoroethylene material.

[0079] The present utility model provides an installation schematic diagram of the lining plate, as Figure 2 shown, the lining plate includes a front lining 111, a side lining 112, and a back lining 113.

[0080] When the powder is high-temperature powder, the function of the inner lining plate is to prevent the outer shell from deforming due to the excessively high temperature of the powder when the high-temperature powder enters from the feed port; the inner lining plate is made of a material with a smooth surface to prevent the powder from sticking to the inner lining plate. On the one hand, this can improve the powder recovery rate, and on the other hand, it can extend the service life of the device. The inner lining plate is made of a non-reactive material to avoid chemical reactions with the powder, which may affect the powder recovery quality and the service life of the recovery bin. In a specific implementation, the metal can be high-temperature powders such as molybdenum powder, tungsten powder, and various alloys.

[0081] According to the design concept of the present utility model, in addition to polytetrafluoroethylene, those skilled in the art can also use other non-reactive materials that can withstand temperatures above 400°C and have a smooth surface to make the inner lining plate.

[0082] On the basis of the above solution, further, as Figures 3-4 shown, the jet pulse cleaning device 200 includes a submerged pulse valve 220, an air bag 210, a submerged through-wall pipe 280, a pulse pipe head 240, a pulse pipe 250, a pulse pipe fixing block 260, a pulse pipe support frame 270, and a submerged compression nut 230;

[0083] The air bag 210 includes an air bag bottom plate 212, an air bag flange 213, an air bag cover plate 214, a left sealing plate 211, and a right sealing plate 215; the air bag 210 can provide compressed air for the jet pulse cleaning device 200 to blow the filter element 310 to remove the dust on the filter element 310.

[0084] The submerged through-wall pipe 280 passes through the air bag bottom plate 212 and is connected to the submerged pulse valve 220. The other end of the submerged through-wall pipe 280 passes through the air bag cover plate 214 and is connected to one end of the pulse pipe head 240 through a submerged compression nut 230. The other end of the pulse pipe head 240 is connected to one end of the pulse pipe 250. The other end of the pulse pipe 250 is fixed to the pulse pipe support frame 270 through a pulse pipe fixing block 260. The pulse pipe support frame 270 is fixed inside the upper space of the recovery bin. The valve seat of the submerged pulse valve 220 is directly embedded in the air bag 210. Such an installation method reduces the flow channel resistance and lowers the jetting air source pressure.

[0085] Preferably, the number of the pulse pipes 250 ≥ 1.

[0086] On the basis of the above solution, further, the pulse tube 250 is selected to have a "U"-shaped structure. The pulse tube 250 is selected to have a "U"-shaped structure, and each side of the "U" shape corresponds to a filter element 310. Therefore, each pulse tube can clean two filter elements 310. The beneficial effects are as follows: It realizes the uniform distribution of the pulse wave in the tube, thereby comprehensively and uniformly cleaning the filter element, improving the cleaning effect and making the cleaning process more efficient; it makes the structure of the pulse tube more compact and occupies less space, which is particularly important for application scenarios with limited space; in addition, during the cleaning process, the "U"-shaped pulse tube generates less noise, effectively reducing the noise generated by the operation of the machine.

[0087] On the basis of the above solution, further, as Figure 3 shown, the filtering device 300 includes a filter element 310. The filter element 310 is vertically placed on the filter element mounting plate 320. The filter element 310 and the filter element mounting plate 320 are directly below the pulse tube 250, and the filter element mounting plate 320 is fixed inside the upper space of the recovery bin.

[0088] Preferably, the filter element 310 is selected to be an elliptical cylindrical filter element.

[0089] Preferably, the number of the filter elements 310 ≥ 2.

[0090] Preferably, the filter element 310 and the filter element mounting plate 320 are detachably connected.

[0091] On the basis of the above solution, further, as Figure 1 and Figure 5 shown, the negative pressure suction device includes a fan housing 450. One end of the fan housing 450 is connected to the fan inlet pipe 410, and one end is connected to the end of the fan motor 460. The fan housing 450 is fixed on the fan bottom plate 470. The fan bottom plate 470 and the filter element fixing frame 440 are fixed on the motor bottom plate 430. The motor bottom plate 430 is fixedly installed on the motor base 420. The fan outer cover 400 covers the motor base 420.

[0092] When the negative pressure suction device is turned on, the fan motor 460 operates, and the gas in the recovery bin is pumped out through the fan pipe 480, forming a negative pressure in the recovery bin. When the powder enters the bin, the generated dust is carried upward by the airflow formed by the fan and adsorbed onto the filter element 310. The gas passes through the filter element 310, and the powder is adsorbed onto the filter element 310, which can efficiently filter the dust in the recovery bin.

[0093] A filter element is installed on the filter element fixing frame 440, aiming to prevent dust in the environment from entering the fan interior and affecting the operation of the fan.

[0094] On the basis of the above solution, further, as Figure 1 shown, the electric control box 500 is fixed on the support frame 600. A timing device is provided inside the electric control box 500. When the timing device inside is turned on, the electric control box 500 controls the jet dust cleaning device 200 to eject gas to remove dust particles on the filter element. The timing device in the electric control box 500 can control the submerged pulse valve 220 to automatically open at intervals for a period of time, which is set according to the amount of dust adsorbed on the filter element 310. When the amount of dust is too large, the interval time of jetting can be appropriately shortened.

[0095] Preferably, the amount of gas generated by the jet dust cleaning device 200 can directly spray the dust on the filter element 310 to the discharge port.

[0096] The new energy battery material powder recovery bin provided by this embodiment can effectively improve the powder recovery rate, effectively reduce the generation and diffusion of dust, and has a simple structure and high automation degree, effectively reducing the labor cost.
