[0022] Reference Figure 1-3 The utility model provides an embodiment: a sand and gravel separation device for a concrete mixing station, comprising a base frame 1, a mixing shell 2 is fixedly connected to the top of the base frame 1, a top cover 3 is fixedly connected to the top of the mixing shell 2, a motor 4 is connected to the middle of the top of the top cover 3 through a fixed frame, a driving end of the motor 4 is connected to a sieve barrel 16 through a cleaning component, a filter plate 9 is provided at the bottom end of the sieve barrel 16, a bottom end of the filter plate 9 is connected to a water tank 13 through a funnel, and a rear end of the water tank 13 is connected to a sprinkler head 18 through a circulation component;
[0023] Specifically, there are partitions 11 at the bottom of the first row of stone openings 10 and the second row of stone openings 12 to prevent water from flowing out when the screen is cleaned. The water in the water tank 13 is pumped out by the water pump 19, and the water is sprayed into the interior of the mixing shell 2 through the sprinkler head 18 to clean the screen. After cleaning the screen, the sewage will pass through the funnel under the filter plate 9 to reach the filter box 14, and after the sewage is filtered by the filter box 14, it reaches the water tank 13. When the screen needs to be cleaned again, the water tank 13, water pipe 17, sprinkler head 18 and water pump 19 cooperate with each other to recycle water resources, thereby reducing the cost of purchasing and processing fresh water, reducing production costs, and improving the economic benefits of the enterprise.
[0024] The cleaning component includes a stirring column 5 located at the driving end of the motor 4, and the left and right ends of the stirring column 5 are fixedly connected to side brushes 6, and the bottom end of the side brush 6 is fixedly connected to a bottom brush 7, and the bottom end of the stirring column 5 is fixedly connected to a brush three 8. The two side brushes 6 are arranged on the inner wall of the screen barrel 16, and the brush three 8 is arranged on the top of the filter plate 9. The circulation component includes a water pipe 17 located at the rear end of the water storage tank 13, and a water pump 19 is installed at the front end of the water pipe 17.

[0025] Specifically, through the mutual cooperation of the motor 4, the side brush 6, the bottom brush 7 and the brush three 8, the motor 4 drives the stirring column 5 to rotate, and the stirring column 5 can drive the side brush 6, the bottom brush 7 and the brush three 8 to move, thereby cleaning the screen barrel 16 and the filter plate 9, the side brush 6 cleans the inner wall of the screen barrel 16, the bottom brush 7 cleans the bottom of the inner wall of the screen barrel 16, and the brush three 8 cleans the filter plate 9. By cleaning the screen, the clogged sand and gravel particles and attached impurities can be removed in time, and the normal working state of the screening device can be restored, thereby maintaining the sand and gravel separation efficiency.
[0026] Working principle: Pour the sand and gravel into the mixing shell 2 from the feeding port 15, start the motor 4, drive the stirring blades on the stirring column 5, and stir the sand and gravel in the screen barrel 16, which is more conducive to the separation of the sand and gravel by the screen barrel 16. The sand and gravel after the first screening by the screen barrel 16 reaches the filter plate 9, and the partition 11 is pulled open. The larger sand and gravel are discharged from the first stone discharge port 10 through the rotation of the bottom brush 7 and the side brush 6, and then the finer sand and gravel fall onto the filter plate 9 and are discharged from the second stone discharge port 10 through the brush 3 8. The second row of stone outlets 12 are discharged. When all the sand and gravel are separated, the water in the water tank 13 is pumped out by the water pump 19, and the water is sprayed into the interior of the mixing shell 2 through the water spray head 18. After long-term use, the screen in the sand and gravel separation device will cause the screen holes to be blocked or accumulated due to the accumulation of sand and gravel particles, the adhesion of mud, etc., which affects the sand and gravel separation efficiency. Through the mutual cooperation of the motor 4, the side brush 6, the bottom brush 7 and the brush three 8, the motor 4 drives the stirring column 5 to rotate, and the stirring column 5 can drive the side brush 6.

By cleaning the screen, the blocked sand and gravel particles and attached impurities can be removed in time, and the normal working state of the screening device can be restored to maintain the sand and gravel separation efficiency. After cleaning the screen, the sewage will pass through the funnel under the filter plate 9 to the filter box 14, and after the sewage is filtered by the filter box 14, it reaches the water storage tank 13. Later, when the screen needs to be cleaned again, the water storage tank 13, water pipe 17, sprinkler head 18 and water pump 19 cooperate with each other to recycle water resources, thereby reducing the cost of purchasing and processing fresh water, reducing production costs and improving the economic benefits of the enterprise. After cleaning, the filter box 14 is pulled out, and the sand and gravel filtered inside the filter box 14 are scattered everywhere, and the filter box 14 is cleaned.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
