If these impurities are not removed in time, it will cause uneven coating layers, defects, and even affect the overall performance of the product. Therefore, it is necessary to filter the slurry, but the existing devices have certain defects. For example, in a Chinese patent with the publication number "CN 220530786 U", a slurry circulating and filtering device for a coater is disclosed, which includes a slurry trolley for storing slurry, and a stirring mechanism for stirring the slurry is installed in the slurry trolley; a slurry pan with a liquid inlet end and a liquid outlet end formed therein, and the liquid inlet end is connected to the slurry trolley through a liquid adding pipeline, and the liquid outlet end is connected to the slurry trolley through a liquid returning pipeline, and pumps are installed on both the liquid adding pipeline and the liquid returning pipeline; a filter installed on the liquid adding pipeline. A filter screen is installed in the filter, and the filter screen is detachably connected to the filter. The filter screen has multiple layers, and the aperture of the filter screen gradually decreases from the end close to the slurry trolley to the end close to the slurry pan. Although this device can filter the slurry, as the use time increases, numerous impurities in the slurry will gradually block the filter screen. Therefore, the filter screen of this device needs to be replaced regularly, and the replacement frequency is high. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 7 As shown, the present utility model provides the following technical solutions:

[0028] A coating machine slurry circulation and filtration device includes a material storage part 1 for storing slurry. A material receiving part 2 is installed on the top of the material storage part 1. The top of the material receiving part 2 is open to form a receiving space for the coating roller. A filter part 4 is installed between the material storage part 1 and the material receiving part 2, and a conveying channel for conveying slurry along a preset path is formed among the material storage part 1, the filter part 4 and the material receiving part 2;

[0029] Moreover, the filter member 4 includes a filter plate 49, a filter screen 410 is installed on the filter plate 49, and a connecting rod 46 is rotatably connected to the feed side of the filter plate 49. One end of the connecting rod 46 is fixedly connected to a scraper 47 for scraping the filter screen 410.

[0030] Through the above technical solution, when personnel need to filter the slurry, the slurry is added to the receiving space on the receiving member 2. When the personnel perform coating through the coater, the coating roller on the coater will contact the receiving space on the receiving member 2, thereby coating the material, and the impurities carried during the coating process will flow downward with the slurry into the storage member 1. The slurry in the storage member 1 will be conveyed to the filter member 4. When the slurry passes through the filter member 4, the slurry is filtered by the filter screen 410 on the filter plate 49. The impurities in the slurry will remain on the feed side of the filter screen 410, and the filtered slurry is conveyed to the receiving space, thereby filtering the slurry in a cycle. And when the slurry passes through the filter screen 410 for filtration, the connecting rod 46 rotates relative to the filter plate 49, thereby driving the scraper 47 to rotate. The filter screen 410 is scraped by the scraper 47, thereby preventing impurities from clogging the filter screen 410 and allowing the filter screen 410 to continuously filter the slurry.

[0031] In addition, in the present utility model, the technical solution of the filter member 4 is further refined:

[0032] As Figures 1 - 4 、 Figure 7 shown, the filter member 4 further includes a housing 41. A filter chamber 44 is formed inside the housing 41. The filter plate 49 is installed inside the housing 41, and the bottom of the housing 41 is open to form a discharge port for discharging impurities. A detachable sealing cover 45 is screwed inside the discharge port.

[0033] After the slurry is conveyed into the filter chamber 44 inside the housing 41, the slurry is filtered by the filter screen 410, so that the impurities in the slurry remain at the bottom of the filter chamber 44, and the filtered slurry is discharged through the top of the filter chamber 44.

[0034] In order to make the cleaning of the filter screen 410 by the scraper 47 more thorough, as Figure 7 shown, a plurality of scraping teeth 48 protrude outward on the side of the scraper 47 facing the filter screen 410. When the scraper 47 scrapes the filter screen 410, the cooperation of the scraping teeth 48 makes the cleaning of the filter screen 410 more thorough.

[0035] And, in the present utility model, regarding how the connecting rod 46 rotates, as Figure 7 shown, a second motor 43 is fixedly connected to the top of the housing 41, and the output end of the second motor 43 is connected to the connecting rod 46.

[0036] In this embodiment, when it is necessary to drive the connecting rod 46 to rotate, the second motor 43 operates, and then the second motor 43 drives the connecting rod 46 to rotate, thereby driving the scraper 47 to rotate.

[0037] In addition, in the present utility model, the technical solution of the filter element 4 is further refined:

[0038] As Figures 1 - 4 , Figure 7 shown, the filter element 4 further includes a pump body 411 and a liquid outlet pipe 42. The liquid inlet end of the liquid outlet pipe 42 is communicated with the top of the housing 41. The liquid outlet end of the pump body 411 is fixedly connected to one side of the housing 41, and the liquid outlet end of the pump body 411 is located below the filter screen 410. The liquid inlet end of the pump body 411 is fixedly connected to the storage member 1.

[0039] In this embodiment, when it is necessary to convey the slurry into the housing 41, the pump body 411 operates to absorb the slurry inside the storage cavity 13 and convey it into the filtration cavity 44 inside the housing 41.

[0040] Specifically, in one embodiment, regarding the above-mentioned storage member 1:

[0041] As Figures 1 - 6 shown, the storage member 1 includes a storage barrel 11. The bottom of the storage barrel 11 is fixedly connected with a foot 12, and a storage cavity 13 is formed inside the storage barrel 11.

[0042] In this embodiment, after the slurry is added to the receiving space by the personnel, the slurry flows into the storage cavity 13 inside the storage barrel 11 and is circulated and filtered under the action of the pump body 411.

[0043] Specifically, in one embodiment, regarding the above-mentioned receiving member 2:

[0044] As Figures 1 - 6 shown, the receiving member 2 includes a slurry tray 21. A communicating pipe 23 is fixedly connected between the bottom of the slurry tray 21 and the top of the storage barrel 11. The communicating pipe 23 is communicated with the receiving cavity 22 and the storage cavity 13.

[0045] In this embodiment, the slurry is received by the slurry tray 21, and the slurry is conveyed back into the storage cavity 13 through the communicating pipe 23.

[0046] In order to improve the efficiency of the slurry entering the housing 41, as Figures 5 - 6 shown, a guide plate 14 is fixedly connected inside the storage cavity 13. The guide plate 14 is inclined downward from one side to the other side to form a guide slope 15.

[0047] In this embodiment, when the slurry flows, through the cooperation of the guide plate 14 and the guide slope 15, the slurry is facilitated to be sucked by the pump body 411.

[0048] In order to stir the slurry inside the storage cavity 13, as Figure 1 、 Figure 4 、- Figure 6 shown, a stirring member 3 for stirring the slurry is provided on the storage barrel 11, and the stirring member 3 is inside the storage cavity 13.

[0049] In this embodiment, by operating the stirring member 3, the slurry inside the storage cavity 13 is stirred.

[0050] Specifically, in one embodiment, regarding the above-mentioned stirring member 3:

[0051] As Figures 4 - 6 shown, the stirring member 3 includes a connecting shaft 32, the connecting shaft 32 is rotatably connected inside the storage cavity 13, and two side plates 33 are symmetrically and fixedly connected to the circumferential surface of the connecting shaft 32. A first motor 31 is fixedly connected to the outside of the storage barrel 11, and the output end of the first motor 31 is connected to the connecting shaft 32.

[0052] In this embodiment, when the slurry needs to be stirred, the first motor 31 is operated to drive the connecting shaft 32 to rotate, and the side plates 33 are driven to rotate by the connecting shaft 32, thereby stirring the slurry inside the storage cavity 13.
