Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a slurry recovery device for commercial concrete plants. Background Technology

[0002] Commercial concrete plants generate a large amount of slurry during the production process. If this slurry is discharged directly, it will not only cause environmental pollution but also waste precious water resources. By recycling and treating this slurry, environmental pollution can be reduced, pollution problems can be effectively solved, the environment can be protected, and the amount of fresh water used can be greatly reduced, thus saving water resources. At the same time, the useful components in the wastewater can be recovered and reused, which can improve resource utilization efficiency.

[0003] Existing technologies for recovering slurry from commercial concrete plants require the use of disinfectants to disinfect the slurry. A common approach is to directly inject the slurry into a disinfection tank, spray it with disinfectant, and then allow it to settle. However, this method suffers from several drawbacks. Since the bottom layer of the slurry contains a large amount of mud, and the primary focus of recovery is the clarified liquid, this mud also consumes a significant amount of disinfectant, increasing material costs and resulting in disinfectant waste. Furthermore, conventional recovery devices cannot achieve continuous injection and discharge. Injecting disinfectant into a flowing liquid leads to variations in disinfection effectiveness at different flow rates, making it impossible to ensure consistent disinfection results at any given time. Based on these issues, a Chinese patent... Patent CN118833913A discloses a slurry recovery device for commercial concrete plants. This device uses a buffer tank and a flow guiding mechanism to continuously guide the upper clarified liquid into the purification and disinfection components, thus reducing the amount of disinfectant consumed by the bottom slurry. The device enables continuous injection and discharge, and the flow guiding mechanism can always guide the upper clarified liquid slurry at a fixed depth, thereby maintaining a constant water pressure and slurry delivery rate. This ensures that the slurry at any given time receives consistent and balanced disinfection time and effect, and can also automatically stop delivery when the slurry volume is insufficient.

[0004] The docking sleeve in the recycling device is located below the outer wall of one side of the disinfection tank. Therefore, the slurry flowing into the disinfection tank from the guide pipe accumulates and blocks the docking sleeve, which not only hinders the normal recycling progress of the slurry, but also affects the efficiency of wastewater treatment.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

When the sedimentation tank moves up, the slide pipe will slide down. At this time, the booster pump can continuously extract the uppermost layer of clarified liquid slurry while the water level in the sedimentation tank drops. Attached Figure Description
