DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 A kind of pre-mixed concrete coarse impurity filtering device in the embodiment, including filter box 1, filter box 1 It is internally provided with filter bin 2, the top of filter box 1 It is provided with feed inlet 3, the inside of filter bin 2 It is provided with multistage filtering assembly 4, the right side surface of filter box 1 It is fixedly installed with control panel 5, the left and right sides of filter box 1 It is installed with conveyor belt 6, the bottom of two conveyor belts 6 It is fixedly installed with support 7, the left and right sides of filter box 1 It is provided with through port 8, the bottom surface of filter box 1 It is provided with discharge port 9.

[0023] The feeding port 3, the filtering bin 2, the two through ports 8 and the discharging port 9 are in communication, and the through ports 8 on the left and right sides are different in height.

[0024] In the embodiment, in use, the ready-mixed concrete enters the filtering bin 2 through the feeding port 3 at the top of the filtering box 1, and is sequentially filtered at different accuracies under the action of the multi-stage filtering assembly 4. The pore sizes of the filtering screens of the multi-stage filtering assembly 4 are arranged from large to small, so that the coarse impurities such as stones and wood blocks with large particle sizes are first intercepted, and the impurities with small particle sizes are gradually filtered out as the concrete flows in the filtering bin 2, so as to ensure the purity of the concrete. In the filtering process, the operator can adjust the filtering speed, the running speed of the conveying belt 6 and the like according to actual needs through the control panel 5 on the right surface of the filtering box 1 to monitor the parameter setting and the running state of the filtering device, so as to ensure that the filtering process is stable and efficient.

[0025] The coarse impurities filtered out are discharged through the discharging port 9 on the bottom surface of the filtering box 1 under the action of gravity, so as to be conveniently collected and cleaned. The ready-mixed concrete filtered out is respectively conveyed into the corresponding conveying belt 6 through the through ports 8 on the left and right sides of the filtering box 1, and the conveying belt 6 stably runs under the support of the support 7 to convey the filtered concrete to a designated position for subsequent construction.

[0026] The multi-stage filtering assembly 4 comprises two mounting plates 401 fixedly installed on the front surface of the filtering box 1. The top surface of the top mounting plate 401 is fixedly installed with a driving motor 402. The output shaft of the driving motor 402 is fixedly installed with a worm 403. The inside of the filtering bin 2 is rotatably installed with three rotating rods 404. The surfaces of the three rotating rods 404 are fixedly installed with three worm gears 405. The surfaces of the three rotating rods 404 are welded with three cams 406. The inside of the filtering bin 2 is movably installed with three filtering plates 407.

[0027] The three filtering plates 407 are all designed as inclined surfaces, and the pore sizes of the three filtering plates 407 increase from top to bottom.

[0028] The three worm gears 405 are all located on the front surface of the filtering box 1, and the surfaces of the three worm gears 405 are all in engagement with the surface of the worm 403.

[0029] The discharging ends of two of the filtering plates 407 are in contact with the through ports 8 and located on the top of the conveying belt 6. The three cams 406 are all located on the bottom of the filtering plate 407 and close to the bottom of the filtering plate 407.

[0030] In the embodiment, when the ready-mixed concrete enters the filter bin 2 from the feeding port 3, the driving motor 402 is powered on and starts to work, and the output shaft drives the worm 403 to rotate. Since the three worm gears 405 are all engaged with the worm 403, the worm 403 drives the three worm gears 405 to rotate synchronously when the worm 403 rotates, and further drives the three rotating rods 404 to rotate. During the rotation of the rotating rods 404, the cams 406 fixed on the surfaces of the rotating rods 404 also rotate. When the protruding part of the cam 406 contacts the bottom of the filter plate 407, the filter plate 407 is lifted upward. When the protruding part rotates away, the filter plate 407 falls back under the action of its own gravity, so that the filter plate 407 vibrates up and down. The ready-mixed concrete flows on the filter plates 407 with three different hole diameters and inclined surfaces. The impurities with large particle sizes are intercepted by the upper filter plate 407 with a small hole diameter, and the impurities slide down the inclined surface to the lower filter plate 407 or are directly discharged from the discharge end. The concrete particles with small particle sizes continue to flow downward through the pores of the filter plate 407, and finally the filtered concrete is discharged from the discharge end of the filter plate 407 in contact with the through port 8 and falls on the conveyor belt 6 to be conveyed away.

[0031] In the embodiment, the three filter plates 407 with different hole diameters are arranged in order from large to small from top to bottom, which can realize multi-stage accurate filtration of the ready-mixed concrete, effectively separate impurities with different particle sizes, and improve the purity of the concrete. Meanwhile, the cooperation of the cam 406 and the filter plate 407 causes the filter plate 407 to vibrate, which can prevent the pores of the filter plate 407 from being blocked by concrete particles, ensure the filtering efficiency, and also help the impurities to slide down the inclined surface and accelerate the discharge speed of the impurities.

[0032] In summary, the ready-mixed concrete coarse impurity filtering device can filter the ready-mixed concrete entering the filter bin 2 by gradient filtration through the filter plates 407 with three hole diameters arranged from small to large in the multi-stage filter assembly 4. The upper filter plate 407 with a small hole diameter intercepts impurities such as large stone blocks and wood blocks, and the lower filter plate 407 with a large hole diameter further filters smaller particles, effectively separates impurities with different particle sizes, ensures the purity of the concrete discharged from the through port 8 and conveyed by the conveyor belt 6, and meets the high-standard requirements of construction.

[0033] Moreover, the driving motor 402 drives the rotating rod 404 and the cam 406 to rotate through the worm 403 and the worm gear 405, so that the filter plate 407 vibrates up and down. The vibration effect prevents the pores of the filter plate 407 from being blocked by concrete particles, ensures the smoothness of the filtering process, promotes the impurities on the inclined surface to slide down quickly, discharges the impurities through the discharge port 9, accelerates the discharge speed of the impurities, and significantly improves the overall filtering efficiency compared with the traditional static filtration.
