[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] like Figures 1 to 5 As shown, the present invention provides a sand and gravel separation and screening device for kaolin production, including a box body 1. The inner cavity of the box body 1 is provided with a scraping mechanism 2. The scraping mechanism 2 includes a drive motor 201, a drive shaft 202 and a scraping plate 203. The bottom end of the drive motor 201 is fixedly installed on the top end of the box body 1. The top end of the drive shaft 202 passes through the inner cavity of the box body 1 and is fixedly connected to the output end of the drive motor 201. The inner side of the scraping plate 203 is fixedly connected to the lower surface of the drive shaft 202. A filter box 3 is fixedly installed on the upper part of the inner cavity of the box body 1. A screening screen plate 4 is fixedly connected to the bottom end of the filter box 3. The bottom end of the scraping plate 203 is movably connected to the top end of the screening screen plate 4. A connecting pipe head 5 is fixedly connected to the left side of the box body 1. The output end of the connecting pipe head 5 passes through the inner cavity of the box body 1 and is fixedly connected to a spray pipe 6.

[0023] refer to Figures 1 to 5 The bottom of the inner cavity of the box 1 is provided with a slope 7. The left side of the top of the box 1 is fixedly connected to the feed port 8. The right side of the box 1 is fixedly connected to the output end of the filter box 3. The right side of the box 1 is fixedly connected to the right side of the slope 7. The back of the box 1 is fixedly installed with a maintenance cover plate 11 by bolts. The contact surface between the maintenance cover plate 11 and the box 1 is provided with a sealing strip.

[0024] The above scheme allows for the convenient discharge of flushing fluid and kaolin through the slope 7, preventing their accumulation and blockage. The internal components of the device can be inspected and replaced through the inspection cover 11, preventing component failures from affecting the operation of the device and improving the stability of the device's operation.

[0025] refer to Figures 1 to 5A support plate 12 is fixedly connected to the bottom of the housing 1, and a device base 13 is fixedly connected to the bottom of the support plate 12. A bearing body 14 is fixedly sleeved on the bottom surface of the drive shaft 202. The surface of the bearing body 14 is fixedly sleeved in the inner cavity of the screening screen plate 4. A limiting groove 15 is opened in the inner cavity of the housing 1. A limiting block 16 is fixedly connected to the surface of the filter box 3. The surface of the limiting block 16 is movably connected to the inner cavity of the limiting groove 15.

[0026] The above solution is adopted as follows: the support plate 12 and the device base 13 can support and fix the device, and prevent the device from shaking during operation. The bearing body 14 can reduce the surface wear of the drive shaft 202 and prevent it from breaking during operation. The limit groove 15 and the limit block 16 can install and remove the filter box 3 and limit its position during operation.

[0027] Working principle:

[0028] During use, the crushed kaolin is conveyed to the inner cavity of the box 1 through the feed inlet 8. The kaolin is filtered through the screening screen plate 4 to separate it from the sand and gravel. At the same time, the rinsing liquid is conveyed to the spray pipe 6 through the connecting pipe head 5 and sprayed out through the spray pipe 6 to rinse the kaolin on the surface of the sand and gravel and dilute it, so that the kaolin can be filtered quickly. Meanwhile, the operation of the drive motor 201 drives the drive shaft 202 to rotate. The rotation of the drive shaft 202 drives the scraper plate 203 to swing, thereby pushing the sand and gravel to the outer side of the screening screen plate 4 and discharging it from the output end of the filter box 3 to the stone discharge plate 9. The swing of the scraper plate 203 pushes away the sand and gravel on the surface of the screening screen plate 4 to prevent it from accumulating and causing blockage. The separated kaolin falls onto the surface of the slope 7 and flows to the lower part by gravity, and is then discharged through the soil discharge plate 10.

[0029] In summary, this sand and gravel separation and screening device for kaolin production solves the problems of existing equipment failing to separate kaolin from sand and gravel during actual use, which easily leads to the waste of kaolin, and the accumulation of sand and gravel and easy clogging of the filter mesh during the filtration and separation process, through the coordinated operation of the scraping and pushing mechanism 2, filter box 3, screening screen plate 4, connecting pipe head 5 and spray pipe 6.
