Description

Technical Field

[0001] This utility model relates to the field of building environmental protection technology, specifically to a slurry recycling device used in commercial concrete production. Background Technology

[0002] The production of ready-mixed concrete generates a large amount of slurry waste, which contains a certain proportion of cement particles and other impurities. Traditional treatment methods involve direct discharge or simple sedimentation followed by discharge, which not only wastes resources but also pollutes the environment.

[0003] A patent document with publication number CN215939290U discloses a slurry recovery device used in commercial concrete production, including a filter bucket, a filter screen, a sedimentation chamber, a sedimentation plate, and a recovery tank. The filter bucket is located above the sedimentation chamber, and the recovery tank is located below the sedimentation chamber. A magnetic stir bar is installed in the recovery tank, and a control chamber is located below the recovery tank. The control chamber contains a control module, a drive motor, a magnet, and a power supply module, and a control box is located on the outside of the control chamber.

[0004] However, the above-mentioned devices have the following problems when in use: When the existing devices are in use, they all separate particles from water through filter plates. The slag on the filter plates cannot be discharged in time. The filter plates can only be manually removed and cleaned by hand. The continuity of slurry treatment is poor and the efficiency is low. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and propose a slurry recycling device for use in commercial concrete production. Through key technologies such as rotary separation, gravity assistance and vibration slag discharge, it not only realizes multi-stage screening of particles in the slurry, which facilitates subsequent processing, but also enables uninterrupted slurry treatment, thereby improving the overall production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slurry recycling device used in commercial concrete production includes a machine body, a pumping pipe embedded in the machine body, an injection port on the machine body, a conveying pipe embedded in the injection port, a rotating outer cylinder rotatably mounted on the machine body, a rotating inner cylinder fixedly mounted on the rotating outer cylinder through a connecting ring, and a drive mechanism on the machine body.

[0008] The rotating inner cylinder is installed at an angle, and a connecting cylinder is fixedly installed on the lower end of the rotating inner cylinder;

[0009] Two slag discharge plates are rotatably mounted on the machine body, and the two slag discharge plates are located directly below the outlets of the rotating outer cylinder and the connecting cylinder, respectively. The machine body is designed with a jacking mechanism.

[0010] The machine body is fitted with filter plates.

[0011] Preferably, the two slag discharge plates face different directions.

[0012] Preferably, the drive device includes a drive motor, fixed shafts, and a running track. There are two fixed shafts, both of which are rotatably mounted on the machine body. Drive wheels are fixedly mounted on the fixed shafts. A first synchronous belt is provided between the two fixed shafts through a pulley. The drive motor is mounted on the machine body, and the output end of the drive motor shaft is fixedly connected to one of the fixed shafts. The running track is fixedly mounted on the rotating outer cylinder, and the running track is adapted to the corresponding drive wheel.

[0013] Preferably, the jacking mechanism includes a second synchronous belt, a drive rod, and a cam. The drive rod is rotatably mounted on the machine body, and the second synchronous belt is sleeved between the drive rod and the corresponding fixed shaft through a pulley.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention utilizes key technologies such as rotary separation, gravity assistance, and vibration discharge to achieve effective recovery and recycling of slurry during concrete production. The rotary separation mechanism, driven by a motor, traps larger particles in the inner cylinder, while smaller particles and clear liquid are discharged through the outer cylinder, efficiently classifying particles in the slurry by size. The vibrating discharge plate design facilitates smooth discharge of slag, improving feeding efficiency. Furthermore, the inclined filter plate further intercepts suspended solids and small particles, ensuring effective filtration. This not only achieves multi-stage screening of particles in the slurry for easier subsequent processing but also enables continuous slurry treatment, improving overall production efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 6 A slurry recycling device used in commercial concrete production includes a body 1, on which a pumping pipe 6 is embedded. The pumping pipe 6 is used to extract the clear liquid portion of the slurry that has been filtered inside the body 1, so that it can be reused in concrete production activities, which facilitates the recycling of resources.

[0027] The machine body 1 is provided with a liquid injection port 4, and a conveying pipe 5 is embedded in the liquid injection port 4. The slurry to be treated is injected through the liquid injection port 4 and discharged through the conveying pipe 5. It is worth noting that the outlet of the conveying pipe 5 is located inside the rotating inner cylinder 3.

[0028] A rotating outer cylinder 2 is rotatably mounted on the machine body 1. A rotating inner cylinder 3 is fixedly mounted on the rotating outer cylinder 2 through a connecting ring 14. A drive mechanism is provided on the machine body 1, and a corresponding support device should be installed on it to ensure safe and stable rotational movement.

[0029] The aperture of the rotating outer cylinder 2 is smaller than that of the rotating inner cylinder 3, which allows larger particles to be successfully trapped inside the rotating inner cylinder 3, while smaller particles fall into the rotating outer cylinder 2. This ensures that only extremely fine particles and water can pass through the holes of the upper rotating outer cylinder 2 and fall into the machine body 1 for further filtration.

[0030] The rotating inner cylinder 3 is installed at an angle, and a connecting cylinder 15 is fixedly installed on the lower end of the rotating inner cylinder 3. The angled installation of the rotating inner cylinder 3 allows the particles inside the rotating inner cylinder 3 and the rotating outer cylinder 2 to move smoothly and be discharged under the action of gravity. The particles inside the rotating inner cylinder 3 are discharged through the lower end of the connecting cylinder 15, and the particles inside the rotating outer cylinder 2 are discharged through the lower end of the rotating outer cylinder 2.

[0031] Two slag discharge plates 12 are rotatably mounted on the machine body 1, and the two slag discharge plates 12 are located directly below the outlets of the rotating outer cylinder 2 and the connecting cylinder 15, respectively. The machine body 1 is designed with a jacking mechanism.

[0032] After discharge, the slag falls smoothly into the corresponding slag discharge plate 12. The design of the jacking mechanism allows the slag discharge plate 12 to vibrate continuously, thereby allowing the material inside the slag discharge plate 12 to flow smoothly, realizing multi-stage screening and making it easier to use.

[0033] A filter plate 16 is embedded in the body 1. The filter plate 16 is used to intercept suspended solids and small particles in the slurry after preliminary filtration to ensure the filtration effect.

[0034] The two slag discharge plates 12 face different directions, allowing for the collection of particles of different sizes at different locations, facilitating sorting and subsequent use.

[0035] The drive unit includes a drive motor 7, a fixed shaft 9, and a running track 10. There are two fixed shafts 9, both of which are rotatably mounted on the machine body 1. A drive wheel 8 is fixedly mounted on the fixed shaft 9, and a first synchronous belt 13 is provided between the two fixed shafts 9 through a pulley.

[0036] The drive motor 7 is mounted on the machine body 1. The output end of the shaft of the drive motor 7 is fixedly connected to one of the fixed shafts 9. The running track 10 is fixedly mounted on the rotating outer cylinder 2, and the running track 10 is adapted to the corresponding drive wheel 8.

[0037] When the drive motor 7 starts, the corresponding fixed shaft 9 rotates. Driven by the first synchronous belt 13, the two fixed shafts 9 rotate synchronously, which in turn causes the drive wheel 8 on them to rotate. Through the cooperation of the drive wheel 8 and the running track 10, the rotating outer cylinder 2 can rotate, which drives the material to move inside the equipment, thereby achieving the screening effect.

[0038] The jacking mechanism includes a second synchronous belt 18, a drive rod 19, and a cam 20. The drive rod 19 is rotatably mounted on the machine body 1. The second synchronous belt 18 is sleeved between the drive rod 19 and the corresponding fixed shaft 9 through a pulley. The cam 20 is fixedly mounted on the drive rod 19.

[0039] There are two jacking mechanisms. The cam 20 is parallel to the corresponding slag discharge plate 12 and is located directly below the corresponding slag discharge plate 12. The cam 20 can directly contact the corresponding slag discharge plate 12.

[0040] When the fixed shaft 9 rotates, the second synchronous belt 18 drives the drive rod 19 to rotate. The rotation of the drive rod 19 causes the cam 20 to intermittently contact the slag discharge plate 12, which in turn allows the slag discharge plate 12 to vibrate slightly around the shaft, thereby improving the material discharge effect.

[0041] The filter plate 16 is inclined, and a slag loading trough 17 is provided at the lower part of the filter plate 16. A slag loading box 11 is movably installed on the slag loading trough 17, and the slag loading box 11 is also provided with filter holes with the same diameter as the filter plate 16.

[0042] The inclined filter plate 16 allows the slag on it to move smoothly to a lower position (i.e., inside the slag box 11) during flushing. The cleaning activity can be completed manually by pulling out the slag box 11 and cleaning its interior. This method is more efficient and easier to use.

[0043] The working process of this utility model;

[0044] Slurry injection: The slurry to be treated enters the device through the injection port 4 and is guided into the rotating inner cylinder 3 through the delivery pipe 5.

[0045] Rotational Separation: After the drive motor 7 starts, it drives the outer cylinder 2 to rotate via the fixed shaft 9, the drive wheel 8, and the first synchronous belt 13. Since the aperture of the outer cylinder 2 is smaller than that of the inner cylinder 3, larger particles in the slurry are trapped inside the inner cylinder 3, while smaller particles enter the outer cylinder 2. The clear liquid and extremely fine particles are discharged through the holes in the outer cylinder 2 and fall into the machine body 1 for further processing.

[0046] Slag discharge: The rotating inner cylinder 3 is installed at an angle, which helps the particles inside move under gravity and be discharged towards the lower end of the connecting cylinder 15. Similarly, the particles inside the rotating outer cylinder 2 also move under gravity and are discharged from its lower end.

[0047] While the fixed shaft 9 rotates, the second synchronous belt 18 causes the drive rod 19 to rotate. The cam 20 on the drive rod 19 intermittently touches the slag discharge plate 12, causing it to vibrate and promoting the falling of slag. This vibration helps the material inside the slag discharge plate 12 to be discharged smoothly, achieving multi-stage screening.

[0048] Interception activity: The filter plate 16 is used to intercept suspended solids and small particles in the slurry after preliminary filtration to ensure the filtration effect. The inclined filter plate 16 allows the slag to move smoothly into the slag box 11 in the slag loading tank 17 under the action of flushing, which is convenient for regular cleaning.

[0049] Clear liquid recovery: The clear liquid after the above steps is extracted through the pumping pipe 6 and then put back into the concrete production process, realizing the recycling of resources.

[0050] 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.
