[0002] Concrete slurry refers to the cement slurry waste liquid generated during the production or use of concrete. It is mainly composed of a mixture of cement, sand, gravel, water, and concrete additives. When concrete slurry is discharged directly without treatment, it will pollute the environment and cause great harm to the ecological environment of the surrounding area. In order to protect the environment and to reuse the sand and gravel separated from the concrete slurry as recycled aggregate in concrete production, so as to realize the recycling of resources, reduce dependence on natural aggregates, and reduce resource waste, the separation of sand and gravel from concrete slurry is a very important step in the process of concrete slurry recycling.

[0003] Mechanical separation is usually used in the recycling of concrete slurry, which is the process of separating sand and gravel from concrete slurry using a filter screen. However, current concrete slurry filtration and separation devices often only have a single layer of filter screen. As a result, concrete slurry accumulates on the surface of the filter screen in a certain place, which affects the separation efficiency of the filter screen for concrete slurry.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-8 This utility model provides a technical solution: a sand and gravel separation device for recycling residual concrete slurry, including a shell 1, a connecting cylinder 2, a support base 3, a discharge pipe 4, a motor 5, a clamping block 6, a filter cylinder 7, a clamping groove 8, a cylinder cover 9, a feed pipe 10, a partition plate 11, an air bag 12, and a micro air pump 13.

[0033] The outer shell 1 is a hollow cylindrical structure. A circular opening is provided through the upper surface of the outer shell 1. A connecting cylinder 2 is fixedly installed on the inner wall of the circular opening on the upper surface of the outer shell 1. Both ends of the connecting cylinder 2 are open, and an annular protrusion is provided on the upper surface of the connecting cylinder 2. A support base 3 is fixedly installed on the bottom surface inside the outer shell 1. The support base 3 is located at the center of the bottom surface of the outer shell 1. The support base 3 is a hollow frustum structure. A circular groove is provided on the upper surface of the support base 3. A discharge pipe 4 is symmetrically arranged on both sides of the support base 3. The discharge pipe 4 is provided through the bottom surface of the outer shell 1. A valve is provided inside the discharge pipe 4 to control its opening and closing.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, during the process of filtering and separating concrete residue using this device, the filter cylinder 7 is installed inside the outer shell 1, and the concrete residue is fed into the filter cylinder 7. The rotating filter cylinder 7 centrifugally filters the concrete residue, allowing the water in the concrete residue to pass through the filter cylinder 7 and enter the outer shell 1, while the sand and gravel in the concrete residue are intercepted inside the filter cylinder 7. The water can be collected using the discharge pipe 4, while the sand and gravel in the concrete residue can be collected along with the disassembled filter cylinder 7.

[0035] The outer casing 1 has an internal filter structure. Rotating the filter structure allows for the filtration of concrete slurry through a detachable filter cylinder 7, facilitating easy disassembly and cleaning of the filter cylinder 7. The filter structure includes a motor 5, which is located inside the support base 3 and embedded in the bottom surface of the outer casing 1. A locking block 6 is fixedly connected to the output end of the motor 5, penetrating the upper surface of the support base 3. The locking block 6 is located in a groove on the upper surface of the support base 3 and has a cross-shaped protrusion structure. The locking block 6 engages with a slot 8, which is fixedly installed on the lower surface of the filter cylinder 7. The filter cylinder 7 is a hollow cylindrical structure with a circular opening on its upper surface and an annular groove. A screw thread is installed on the inner wall of the groove on the upper surface of the filter cylinder 7. The filter cylinder 7 has a cover 9 on its upper surface. The outer surface of the cover 9 matches the threaded groove on the upper surface of the filter cylinder 7. A feed pipe 10 is provided through the surface of the cover 9. Two handles are symmetrically arranged on the upper surface of the cover 9. The outer diameter of the filter cylinder 7 is equal to the inner diameter of the connecting cylinder 2. A reinforcing structure is provided on the inner surface of the connecting cylinder 2. The reinforcing structure uses an airbag 12 to fix the filter cylinder 7 in the vertical direction. The reinforcing structure includes an airbag 12. The airbag 12 is a ring structure and is fixedly installed on the inner surface of the connecting cylinder 2. The airbag 12 is an inflatable structure. A connecting pipe is provided through the surface of the airbag 12. The connecting pipe on the surface of the airbag 12 is connected to a micro air pump 13. The micro air pump 13 is fixedly installed on a protruding surface on the outer surface of the connecting cylinder 2.

[0036] like Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, during the installation of the filter cylinder 7, hold the handle on the upper surface of the cylinder cover 9 and connect the cylinder cover 9 to the threaded groove on the upper surface of the filter cylinder 7, so that the filter cylinder 7 is connected to the cylinder cover 9. Insert the filter cylinder 7 into the inner surface of the connecting cylinder 2 on the upper surface of the outer shell 1, so that the slot 8 connected to the lower surface of the filter cylinder 7 engages downward with the locking block 6 and engages with the circular groove on the upper surface of the support base 3. At this time, the lower surface of the filter cylinder 7 is in contact with the upper surface of the support base 3. Start the micro air pump 13, and the micro air pump 13 inflates the air bag 12, causing the air bag 12 to expand. The expanded air bag 12 reinforces and blocks the upper surface of the filter cylinder 7, preventing the filter cylinder 7 from displacing vertically. Connect the feed pipe 10 on the upper surface of the cylinder cover 9 to the concrete residue, so that the concrete residue can enter the interior of the filter cylinder 7. Start the motor 5, and the motor 5 drives the locking block 6 to rotate. The locking block 6 drives the locking slot 8 to rotate, which in turn drives the filter cylinder 7 to rotate. The rotating filter cylinder 7 can perform a centrifugal separation process on the concrete residue inside.

[0037] The filter cylinder 7 has an internal partition structure. The partition structure separates the concrete residue through the partition plate 11, thereby increasing the filtration efficiency. The partition structure includes the partition plate 11, which is an inverted conical plate structure that runs vertically through the filter cylinder. The surface of the partition plate 11 is provided with circular filter holes. The partition plate 11 is fixedly installed on the inner wall of the filter cylinder 7. Multiple partition plates 11 are arranged parallel to each other on the inner wall of the filter cylinder 7. Circular filter holes are provided on the surface of the filter cylinder 7 between every two partition plates 11.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, when the residual concrete slurry enters the interior of the filter cylinder 7, it will be evenly distributed to the inner wall of the filter cylinder 7 by the separation effect of multiple partition plates 11 set inside the filter cylinder 7, and will be filtered and separated along the circular filter holes on the surface of the filter cylinder 7, so as to avoid the accumulation of residual concrete slurry on the surface of the filter cylinder 7 and affect the filtration and separation process of residual concrete slurry.

[0039] Working principle: When using this sand and gravel separation equipment for recovering residual concrete slurry, connect the cylinder cover 9 to the filter cylinder 7, and insert the filter cylinder 7 into the outer shell 1, so that the groove 8 on the lower surface of the filter cylinder 7 engages with the locking block 6. Start the micro air pump 13, which inflates the air bladder 12, reinforcing the vertical direction of the filter cylinder 7 and preventing vertical displacement. Start the motor 5, which drives the locking block 6 to rotate, which in turn drives the groove 8 to rotate, thereby rotating the filter cylinder 7. At this time, the residual concrete slurry enters the filter cylinder 7 and is evenly distributed on the inner wall of the filter cylinder 7 under the action of the partition plate 11. Under the action of the rotating filter cylinder 7, a centrifugal filtration separation process occurs, preventing the residual concrete slurry from accumulating on the surface of the filter cylinder 7 and increasing the overall practicality.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
