[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0021] like Figures 1 to 4In the embodiment of the ready-mixed concrete screening and filtering device of the utility model shown, the ready-mixed concrete screening and filtering device includes a main frame 1, in which an inclined filter frame 2 is fixedly provided, and the horizontal height of the filter frame 2 at its feed end 201 close to the feed port 11 is higher than its slag discharge end 202 close to the discharge port 12, the feed end 201 and the slag discharge end 202 are respectively parallel to the horizontal plane, and a filter screen 3 is provided in the filter frame 2; when the ready-mixed concrete slurry enters from the feed port 11, it will be screened by the filter screen 3, and the slurry that passes the screening will pass through the sieve holes of the filter screen 3 and be discharged from the discharge port 12, and the screened agglomerates or large-diameter particles will be discharged from the slag discharge port 13 connected to the slag discharge end 202.

[0022] A filter opening 101 is provided on the side wall of the main frame 1 at the feed end 201, and an opening is provided at the feed end 201 of the filter frame 2. A filter 3 is slidably provided in the filter frame 2, and the filter 3 can be slidably taken out from the filter opening 101 and the opening, and a handle 33 is provided on the filter 3; the outer periphery of the filter frame 2 is fixedly connected to the main frame 1, and the inner periphery of the filter frame 2 is provided with a boss supporting the outer periphery of the filter 3, and the filter 3 can slide on the boss and is limited by the outer periphery of the filter frame 2 to slide only between the feed end 201 and the slag discharge end 202 of the filter frame 2; due to the characteristics of premixed concrete, the concrete adhered to the filter 3 may solidify, so after each use of the device, the filter 3 can be quickly pulled out and rinsed using the handle, and the cleaning process is convenient and efficient, and a good cleaning effect is guaranteed.

[0023] A plurality of filter strips 31 perpendicular to the feed end 201 and the slag discharge end 202 are fixedly provided on the filter screen 3, and the filter strips 31 extend from the feed end 201 to the slag discharge end 202, and a wave pattern 311 is provided on the top of the filter strip 31; since the premixed concrete is relatively viscous, the concrete is easily discharged along with the agglomerates or large particles, resulting in concrete waste, and therefore the use of the wave pattern 311 can make the agglomerates or large particles vibrate as much as possible when passing through the filter screen 3, thereby vibrating off the viscous concrete slurry on the agglomerates or large particles, thereby achieving a good filtering effect and reducing the loss of concrete.

[0024] In one embodiment of the present application, preferably, a reinforcement strip 32 perpendicular to the filter strip 31 is fixedly provided on the bottom end surface of the filter screen 3, and the top height of the reinforcement strip 32 is lower than the filter strip 31 at the connection point; on the one hand, the reinforcement strip 32 can play a role in reinforcing the overall structural strength of the filter screen 3, and on the other hand, it can prevent coagulation blocks or large particles from being stuck in the filter screen 3 to a certain extent due to sinking into the gap of the filter screen 3 too deeply; the top height of the reinforcement strip 32 is lower than the filter strip 31 at the connection point, so it will not intercept coagulation blocks or large particles and cause material jamming.

[0025] In one embodiment of the present application, preferably, the top of the reinforcement strip 32 is set to be rounded or pointed to prevent the slurry from accumulating on the top of the reinforcement strip 31 .

[0026] In one embodiment of the present application, preferably, the main frame 1 includes a support beam 15 and a shell 16, and the filter frame 2, the feed port 11, the discharge port 12 and the slag discharge port 13 are fixedly connected to the support beam 15; the support beam 15 can be fixedly connected to the filter frame 2, the feed port 11, the discharge port 12 and the slag discharge port 13 by welding. The provision of the support beam 15 can make the overall strength of the device higher, and thus the filtering work can be performed with high intensity; the shell 16 plays a role in preventing concrete from splashing out, and the support beam 15 and the shell 16 are fixedly connected by welding.

[0027] In one embodiment of the present application, preferably, a discharge plate 14 is fixedly provided on the main frame 1, the discharge plate 14 is parallel to the filter frame 2 and is located at the lower side of the filter frame 2, and the discharge plate 14 is fixedly connected to the support beam 15; the discharge plate 14 and the support beam 15 can also be fixedly connected by welding, thereby improving the structural strength of the discharge plate 14 to receive more filtered concrete slurry, thereby improving the filtration efficiency.

[0028] In one embodiment of the present application, preferably, an openable cleaning window 17 is provided on the side wall of the filter opening 101 on the main frame 1 and between the filter frame 2 and the discharge plate 14, and a window handle 171 is provided on the cleaning window 17. By opening the cleaning window 17, the interior of the main frame 1 can be quickly rinsed with water.

[0029] In one embodiment of the present application, preferably, it also includes a support foot 18 , which is connected to the support beam 15 to support the support beam 15 .

[0030] In one embodiment of the present application, preferably, the support leg 18 is connected to the connecting ear 19 of the support beam 15 by a spring, and a vibration motor is also provided on the support beam 15; the relevant structures of the vibration motor and the spring connection are all prior arts and will not be described in detail here; in this embodiment, the addition of the vibration motor and the spring connection related structures can more efficiently make the agglomerates or large particles generate more vibrations due to the wave pattern 311 when passing through the filter screen 3, thereby being able to vibrate off more premixed concrete slurry attached to the agglomerates or large particles.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
