[0020] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall cross-sectional structure of a slag collection device for electrode paste production provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the top view of the support plate provided in an embodiment of the present application. Figure 3Schematic diagram of the cross-sectional structure of the spoiler paddle provided in the embodiment of the present application. The slag collection device 100 used in the production of electrode paste includes a cleaning tank 110. In the embodiment of the present application, the cleaning tank 110 can be a basin with an open top. The specific parameters of the cleaning tank 110 can be set with reference to the prior art. A support plate 120 is provided in the middle of the cleaning tank 110, and the support plate 120 is used to support the conveying device 111. A plurality of leakage grooves 121 are provided on the support plate 120, and a mesh plate 122 is provided in the leakage groove 121. The mesh plate 122 has a certain gap so that the slag can pass through the mesh plate 122 and fall to the bottom of the cleaning tank 110. The gap between the mesh plates 122 can be set according to the maximum particle size of the slag under actual operation conditions, so that all the slag falling off the electrode paste can pass through the mesh plate 122 and fall to the bottom of the cleaning tank 110. A conveying device 111 is provided in the cleaning tank 110. The input end of the conveying device 111 is fixed on the mesh plate 122. The output end of the conveying device 111 is tilted upward and extends to the outside of the cleaning tank 110. The conveying device 111 is a prior art, which is used to convey the electrode paste wool material falling on the top thereof, so that the electrode paste wool material can pass through the cleaning tank 110 under the conveying of the conveying device 111, and then the liquid in the cleaning tank 110 can flush and clean the electrode paste wool material on the top of the conveying device 111. A plurality of material-dividing devices 130 are provided on the support plate 120. The material-dividing devices 130 are used to divert the material residue scattered on the support plate 120 to the top of the mesh plate 122, so that it can pass through the mesh plate 122 and fall into the bottom of the cleaning tank 110. A plurality of material-dividing devices 130 and a plurality of material-leaking troughs 121 are alternately arranged, so as to maximize the working efficiency of the material-dividing devices 130. The material removal device 130 includes a rotating motor 131 fixed to the bottom of the support plate 120, and the rotating motor 131 is connected to a transmission shaft 132. The transmission shaft 132 penetrates upward to the top of the support plate 120 and is connected to a plurality of spoiler paddles 133. The plurality of spoiler paddles 133 are horizontal and arranged in sequence along the axial direction of the rotating shaft. During operation, after the rotating motor 131 is started, the transmission shaft 132 will drive each spoiler paddle 133 to rotate around the central axis of the transmission shaft 132, so that the spoiler paddle 133 drives the material slag scattered on the top of the support plate 120 to fall into the grid plate 122.There is a gap between the spoiler paddle 133 and the top side of the support plate 120. The gap between the spoiler paddle 133 and the support plate 120 is set according to actual usage, and can usually be 3-5 cm. The spoiler paddle 133 will drive the liquid in the cleaning tank 110 to rotate and generate turbulence during the rotation process. At this time, some of the slag with smaller particle sizes will be driven into the grid plate 122 under the action of the turbulence. When the diameter of the slag with larger particle sizes is larger than the gap between the spoiler paddle 133 and the support plate 120, the spoiler paddle 133 will push it to rotate together during the rotation process, thereby pushing it away from the support plate 120 and making it fall onto the grid plate 122. The bottom of the cleaning trough 110 contracts inward to form a V-shaped discharge trough 112. One end of the V-shaped discharge trough 112 is connected to an elevator 140. The discharge end of the elevator 140 is tilted upward and connected to a screening machine. The residue in the cleaning trough 110 will be driven by the elevator 140 to enter the screening machine for screening and recycling.

[0021] As can be seen from the above, in the embodiment of the present application, the cleaning tank 110 can be divided into two parts, an upper part and an lower part, by providing a support plate 120, and the support plate 120 can stably support the conveying device 111. During operation, the electrode paste raw material driven by the conveying device 111 is cleaned by the liquid in the cleaning tank 110. The residue generated will fall into the top of the support plate 120, and enter the top of the mesh plate 122 under the action of the material diverting device 130, and then pass through the mesh plate 122 to fall to the bottom of the cleaning tank 110. Part of the raw material directly falls into the top of the mesh plate 122 and can directly pass through the mesh plate 122 to fall into the bottom of the cleaning tank 110. The residue at the bottom of the cleaning tank 110 can enter the screening machine driven by the elevator 140 for screening and reuse. In the present application, the material removal device 130 includes a rotating motor 131, a transmission shaft 132 and a spoiler paddle 133. When the rotating motor 131 drives the spoiler paddle 133 to rotate, the spoiler paddle 133 will drive water flow during its rotation, and then the water flow acts on the material residue with smaller particle size, flushing it to the top of the mesh plate 122, while the material residue with larger particle size is pushed by the spoiler paddle 133 and enters the mesh plate 122.

[0022] In some embodiments, the interval between the spoiler paddle 133 and the top of the support plate 120 is 3-5 cm.

[0023] In the embodiment of the present application, when the interval between the spoiler paddle 133 and the top of the support plate 120 is within this range, it can ensure that the slag with a particle size smaller than this range can be "blown by the water flow" generated when the spoiler paddle 133 rotates. When the particle size of the slag is larger than this range, the slag can be pushed by the spoiler paddle 133 and enter the grid plate 122 under the action of inertia.

[0024] In some embodiments, the screening machine is a swing screening machine, which has higher screening accuracy and meets the use requirements.

[0025] In some embodiments, the cross section of the spoiler paddle 133 is a semicircular ring, and four spoiler paddles 133 are respectively provided on each transmission shaft 132. In the embodiment of the present application, through the above arrangement, since the cross section of the spoiler paddle 133 is a semicircular ring, the spoiler paddle 133 will have greater strength and will not easily deform. Moreover, when the spoiler paddle 133 rotates, the water flow disturbed by its arc-shaped end surface is more likely to "blow" some of the slag with smaller particle sizes.

[0026] In some embodiments, a lower material bin 150 is provided on one side of the cleaning tank 110, and an L-shaped buffer plate 151 is provided at the bottom opening of the lower material bin 150. One end of the L-shaped buffer plate 151 is hinged to the inner side wall of the cleaning tank 110, and the other end extends to the input end of the conveying device 111. A plurality of elastic components 152 are provided between one side of the L-shaped buffer plate 151 and the inner side wall of the cleaning tank 110. In the embodiment of the present application, through the above-mentioned arrangement, the electrode paste to be cleaned is put into the lower material bin 150 during the working process, and the electrode paste falls onto the L-shaped buffer plate 151, and slides along the end surface of the L-shaped buffer plate 151 to the top of the conveying device 111. In addition, due to the arrangement of the elastic component 152, when the electrode paste falls into the L-shaped buffer plate 151, the L-shaped buffer plate 151 deforms downward to play a buffering role, thereby avoiding a large impact damage to the electrode paste.

[0027] In some embodiments, the elevator 140 is a spiral elevator 140, and the bottom of the spiral elevator 140 is connected to a sewage pipe 160 through a sewage valve 161. In the embodiment of the present application, through the above arrangement, after the device has been working for a long time, the cleaning liquid inside the device will gradually become turbid. At this time, the sewage valve 161 can be opened to discharge the cleaning liquid inside the device from the sewage pipe and then replaced.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
