Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of environmental protection equipment, and specifically refers to a sewage sedimentation tank drainage device for environmental protection use. Background Art
[0002] Environmental protection equipment refers to mechanical products, structures and systems manufactured and built by production units or construction and installation units for controlling environmental pollution and improving environmental quality. It includes various environmental protection machinery and equipment, instruments and meters, treatment devices, etc., such as solid waste treatment equipment, environmental monitoring equipment, air purification equipment, etc. As a kind of environmental protection equipment, a sewage sedimentation tank is a structure used to treat various sewage, and uses the sedimentation effect to remove suspended solids, organic matter, ammonia nitrogen and other pollutants in the water, so as to purify the water quality. During the use of the sewage sedimentation tank, it is necessary to regularly discharge the sewage that meets the discharge standards.
[0003] When the existing sewage sedimentation tank drainage device for environmental protection use is in use, the drainage accuracy is insufficient, and the traditional fixed water level drainage is likely to cause the mixing of the clear water area and the sludge layer. For example, the drainage error of the siphon drainage reaches ±10 cm, and the actual measurement shows that the secondary rising of the sludge will cause the suspended solids in the effluent to exceed the standard by 2-3 times (>30 mg / L); and the mechanical reliability is poor. The transmission components have an average service life of <1 year in a corrosive environment, such as pH 4-10, and the maintenance cost is high. Summary of the Invention
[0004] The technical problem to be solved by the present invention is that the drainage accuracy of the sewage sedimentation tank drainage device for environmental protection use is insufficient during use, and there is a lack of adjustable function to separately treat the clear water area and the sludge layer.
[0005] The technical solution adopted by the present invention is as follows: A sewage sedimentation tank drainage device for environmental protection use proposed by the present invention includes a sewage sedimentation tank body. A clear water area pumping pipeline arranged in an L shape penetrates through the sewage sedimentation tank body. A water pump is connected to the clear water area pumping pipeline. The lower end of the water pump is provided with a water outlet. The front end of the clear water area pumping pipeline is provided with a multi-stage telescopic pipe. The lower end of the multi-stage telescopic pipe is fixedly connected with an annular sleeve. A permanent magnet block is embedded inside the multi-stage telescopic pipe and is covered with a lining made of polytetrafluoroethylene material.
[0006] Furthermore, a magnetic attraction ring magnetically attracted and matched with the permanent magnet block is sleeved outside the annular sleeve. An installation seat is fixedly connected to the sewage sedimentation tank body. A guide rod is slidably arranged on the installation seat. The lower end of the guide rod is fixedly connected with a connecting frame connected to the outer wall of the magnetic attraction ring.
[0007] Furthermore, a cylinder is fixedly connected to the upper part of the installation seat. The output end of the cylinder is fixedly connected with a U-shaped frame. The lower end of the U-shaped frame is fixedly connected with a support plate. The lower part of the support plate is fixedly connected to the top end of the guide rod.
[0008] Further, a sensing device seat is fixedly connected to the front part of the connecting frame, a first microwave turbidity sensor and a second microwave turbidity sensor are fixedly connected to the sensing device seat, and a PLC controller is fixedly connected to the upper part of the mounting seat.
[0009] Further, the first microwave turbidity sensor and the second microwave turbidity sensor are arranged in a 90° cross.
[0010] Further, a water treatment tank is fixedly connected to the outside of the sewage sedimentation tank body and is located below the water outlet. A filter screen is fixedly connected to the inner wall of the water treatment tank, a control valve is arranged on the side wall of the water treatment tank, and a chemical dosing tank is fixedly connected to the upper part of the water treatment tank.
[0011] Further, a discharge valve is arranged on the side wall of the other side of the sewage sedimentation tank body, and a discharge pipe is communicated with the discharge valve.
[0012] The beneficial effects obtained by the present invention with the above structure are as follows:
[0013] 1. By adopting the dynamic drain outlet control technology, the pumping depth during the drainage process is adjusted by using a multi-stage telescopic pipe, the position of the clear water area is controlled, the control error is reduced, the sludge disturbance is reduced, and the problem of mixed discharge is avoided;
[0014] 2. An anti-corrosion material is adopted in the pipeline, the pipeline lining is made of PTFE material, and at the same time, magnetic force is used for non-contact support control to overcome the problem that transmission components are easily damaged in the environment.
