Description

Technical Field

[0001] The utility model relates to the technical field of concrete sedimentation tanks, in particular to an enhanced concrete sedimentation tank. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. Among them, a concrete sedimentation tank is a structure that uses sedimentation to remove suspended matter in water. At present, after cleaning a concrete mixer truck, a large amount of concrete will be mixed in its liquid. In order to recycle the concrete, the liquid after cleaning is usually discharged into a sedimentation tank for sedimentation. Solid substances such as silt, aggregates and admixtures in the concrete will be deposited in the sedimentation tank. People can recycle the precipitated solid substances, thereby achieving the recycling of water and concrete. For example, application number: 202220795737.7 relates to a concrete sedimentation tank that is easy to clean, which includes a tank body, a drain outlet is connected to the tank body, and a drain outlet is provided on the tank body. A first baffle plate for closing the drainage port is provided, a mud discharge port is provided on the pool body, a second baffle plate for closing the mud discharge port is provided on the pool body, a mud scraper plate for scraping off the sediment on the pool body wall is provided in the pool body and slides in a direction close to or away from the mud discharge port, a driving assembly for driving the mud scraper plate to slide is provided on the pool body, when cleaning and collecting the sediment in the sedimentation tank, the first baffle plate is first opened to allow the water in the sedimentation tank to be discharged from the drainage port, the second baffle plate is opened after the water is drained, and the mud scraper plate is driven by the driving assembly to slide in a direction close to the mud discharge port, the mud scraper plate scrapes the sediment toward the mud discharge port, the staff can directly collect the sediment at the mud discharge port, no need to manually clean the sedimentation tank, which is conducive to improving the cleaning effect of the sedimentation tank;

[0003] The concrete sedimentation tank disclosed in the above patent discharges the water in the sedimentation tank through the drain port, and then discharges the concrete after the water is drained, so as to achieve the effect of separating water and concrete sediment. However, it still has some shortcomings: 1. Since the position of the drain port is fixed, the water below the drain port cannot be effectively and quickly discharged. Even if the water can be pumped out with the help of a water pump, the water close to the liquid surface of the concrete sediment will be pumped out together with the concrete and water under the extraction force, affecting the separation effect; 2. After the sediment is cleaned out, there is a lack of structure for cleaning the impurities attached to the sedimentation tank, which cannot meet the use requirements. Based on the above situation, the above patent is redesigned, so we propose an enhanced concrete sedimentation tank. Utility Model Content

[0027] Working principle: when in use, concrete and water are poured into the sedimentation tank body 100. After standing for a period of time, the concrete sediment settles to the top of the scraper 8, and the water is located above the concrete sediment to form a layer. The layering line is observed through the transparent glass 15. Then the driving motor 6 is started in the positive direction. The output shaft of the driving motor 6 drives the screw 7 to rotate. Under the action of the threaded hole provided on the moving block 5, the screw 7 rotates to drive the moving block 5 to move downward. The moving block 5 drives the blocking plate 3 to slide downward on the L-shaped guide rod 4. While the blocking plate 3 moves downward, it gradually releases the obstruction of the drainage hole 1. When the blocking plate 3 moves downward until its top is flush with the top of the concrete sediment, the right side of the water located above is not blocked, and the water is discharged into the water receiving box 2 through the drainage hole 1, and then discharged by the drainage valve in the open state. At this time, the blocking plate 3 blocks the right side of the concrete sediment, and the concrete sediment will not be discharged. It will only discharge water alone, and the concrete sediment in the lower layer will not be discharged together, thereby enhancing the separation effect of water and concrete.

[0028] After the water is completely discharged, the two electric telescopic rods 9 are started in the forward direction, and the output shaft of the electric telescopic rod 9 drives the scraper 8 to move upward to push the concrete sediment upward from the inside of the sedimentation tank body 100 to discharge it, so that personnel can directly remove the sediment from the upper part. The scraper 8 also stretches the telescopic hose 11 upward. When the sediment is cleaned away, the two electric telescopic rods 9 are started in the reverse direction. Similarly, the movement process of the two electric telescopic rods 9 is opposite to that of the forward start, so that the scraper 8 moves downward to reset and relaxes the tension on the telescopic hose 11, and then the water pump 12 is turned on. The water pump 12 extracts the water inside the water tank 10 and passes through the telescopic hose 11. 1 is discharged into the water supply chamber 13, and the water inside the water supply chamber 13 is sprayed onto the inner wall of the sedimentation tank body 100 through multiple one-way valves 14. While spraying water, the electric telescopic rod 9 is opened forward again, so that the scraper 8 drives the multiple one-way valves 14 to move upward to spray, thereby effectively spraying and cleaning the inner wall of the sedimentation tank body 100. After the water is cleaned, the cleaning water inside the sedimentation tank body 100 can be discharged into the water receiving box 2 through the drainage hole 1, and the water inside the water receiving box 2 can be discharged to the outside through the drainage valve, thereby achieving the effect of effectively cleaning the impurities attached to the inner wall of the sedimentation tank body 100 after use, without affecting subsequent use.
