Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment accelerated sedimentation device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. With social development, the application of wastewater treatment is becoming more and more widespread, and therefore, the demand for wastewater treatment environmental protection equipment is growing day by day.

[0003] In wastewater treatment equipment, sedimentation devices work by adding flocculants to wastewater, stirring it, and then allowing the flocculants to settle. However, current sedimentation equipment has certain drawbacks: the mixing and sedimentation of wastewater all occur within a single device, requiring a long settling time after stirring, during which the next batch of wastewater cannot be treated, affecting overall treatment efficiency; secondly, the settling process is slow. Therefore, further improvements are needed. To this end, we propose an accelerated sedimentation device for wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater treatment accelerated sedimentation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater treatment accelerated sedimentation device, comprising a base plate, a mixing tank and a sedimentation tank mounted on the upper surface of the base plate, a mixing assembly mounted at the top center of the mixing tank, and a pump body connecting the mixing tank and the sedimentation tank mounted on the top of the mixing tank, an inlet pipe fixed on one side of the top of the mixing tank, a filter plate horizontally arranged at the top of the sedimentation tank, a lifting assembly for driving the filter plate to move mounted on the upper surface of the sedimentation tank, a drain pipe mounted on the bottom side wall of the sedimentation tank, and a sewage discharge pipe fixed on the bottom wall of the sedimentation tank, and a control cabinet mounted on the upper surface of the base plate.

[0006] Furthermore, a dosing port is provided at the top of the mixing tank.

[0007] Furthermore, the stirring assembly includes a first motor fixed to the top of the stirring tank, a vertical shaft fixed to the bottom output end of the first motor, and a stirring blade fixedly connected to the bottom end of the vertical shaft.

[0008] Furthermore, the pump body's water inlet is fixed with a water inlet pipe that extends to the bottom of the mixing tank, and the pump body's drain outlet is fixed with a water delivery pipe that connects to the side wall of the sedimentation tank.

[0009] Furthermore, the lifting assembly includes a housing fixed to the top of the sedimentation tank, the top of the sedimentation tank having a through hole, a vertical rod being provided inside the housing, the vertical rod passing through the through hole and slidably connected to the through hole, the bottom end of the vertical rod being fixedly connected to the filter plate, a second motor being fixedly fixed to the bottom end inside the housing, a lead screw being fixed to the top output end of the second motor, a top plate being rotatably connected to the surface of the lead screw via threads, and the top end of the vertical rod being fixedly connected to the top plate.

[0010] Furthermore, valves are installed in the middle of both the drainage pipe and the sewage pipe.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model is equipped with a base plate, a mixing tank, a sedimentation tank, a mixing assembly, and a pump body. By setting up a mixing tank and a sedimentation tank, the flocculation and sedimentation of sewage are carried out separately. The sewage is first mixed with the chemical solution in the mixing tank, and then the mixed sewage is pumped into the sedimentation tank for sedimentation. The emptied mixing tank can continue to be mixed, thereby improving the efficiency of sewage treatment.

[0013] 2. In use, this utility model is equipped with a sedimentation tank, a filter plate, and a lifting assembly. After the sewage in the mixing tank is pumped into the sedimentation tank, the lifting assembly drives the filter plate to descend. The filter plate can squeeze and push the sediment in the sewage downward, so that the sediment settles quickly. Finally, the sewage and sediment are discharged from the drain pipe and sewage pipe respectively, which further improves the sewage treatment efficiency. Attached Figure Description

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a wastewater treatment accelerated sedimentation device is disclosed, comprising a base plate 1, a mixing tank 2 and a sedimentation tank 3 mounted on the upper surface of the base plate 1, a mixing assembly 4 mounted at the top center of the mixing tank 2, and a pump body 5 connecting the mixing tank 2 and the sedimentation tank 3 mounted on the top of the mixing tank 2, an inlet pipe 6 fixed on one side of the top of the mixing tank 2, a filter plate 7 horizontally arranged at the top of the sedimentation tank 3, a lifting assembly 8 for driving the filter plate 7 to move mounted on the upper surface of the sedimentation tank 3, a drain pipe 9 mounted on the bottom side wall of the sedimentation tank 3, and a sewage pipe 10 fixed on the bottom wall of the sedimentation tank 3, and a control cabinet 11 mounted on the upper surface of the base plate 1.

[0022] In this embodiment, the control cabinet 11 adopts existing control technology. A PLC controller is installed inside the control cabinet 11, which controls the operation of the pump body 5, the stirring assembly 4 and the lifting assembly 8.

[0023] The top of the mixing tank 2 is provided with a chemical addition port 21.

[0024] Flocculant can be added into the mixing tank 2 through the dosing port 21.

[0025] The stirring assembly 4 includes a first motor 41 fixed to the top of the stirring tank 2, a vertical shaft 42 fixed to the bottom output end of the first motor 41, and a stirring blade 43 fixedly connected to the bottom end of the vertical shaft 42.

[0026] The first motor 41 is electrically connected to the control cabinet 11. The first motor 41 is started by the control cabinet 11, and the first motor 41 drives the vertical shaft 42 and the stirring blade 43 to rotate, thereby stirring and mixing the sewage and flocculant through the stirring blade 43.

[0027] The pump body 5 has a water inlet fixed with a water inlet pipe that extends to the bottom of the mixing tank 2. The pump body 5 has a water outlet fixed with a water delivery pipe that is connected to the side wall of the sedimentation tank 3.

[0028] The wastewater that has completed the reaction inside the mixing tank 2 can be pumped into the sedimentation tank 3 through the pump body 5. The filter plate 7 is initially located at the top inside the sedimentation tank 3.

[0029] The lifting assembly 8 includes a housing 81 fixed to the top of the sedimentation tank 3. The top of the sedimentation tank 3 has a through hole 31. A vertical rod 82 is provided inside the housing 81. The rod 82 passes through the through hole 31 and is slidably connected to the through hole 31. The bottom end of the rod 82 is fixedly connected to the filter plate 7. A second motor 84 is fixedly fixed to the bottom end inside the housing 81. A lead screw 85 is fixed to the top output end of the second motor 84. A top plate 83 is rotatably connected to the surface of the lead screw 85 through a thread. The top end of the rod 82 is fixedly connected to the top plate 83.

[0030] The second motor 84 is electrically connected to the control cabinet 11. The control cabinet 11 can control the second motor 84 to rotate forward or in reverse. The second motor 84 is a geared servo motor, and its rotation stroke is controlled by the PLC controller. After the second motor 84 drives the lead screw 85 to rotate forward or in reverse, the lead screw 85 drives the top plate 83 and the vertical rod 82 to move up or down along the through hole 31, thereby driving the filter plate 7 to rise and fall.

[0031] Valves are installed in the middle of both drain pipe 9 and sewage pipe 10.

[0032] In this embodiment, the height of the drain pipe 9 is higher than that of the sewage pipe 10. After the sewage has settled inside the sedimentation tank 3, the settled sewage is discharged from the drain pipe 9 and the settled sludge is discharged through the sewage pipe 10.

[0033] Working Principle: Wastewater is added to the mixing tank 2 through the inlet pipe 6, followed by flocculant added through the dosing port 21. The first motor 41 is then started to rotate the mixing blades 43, agitating the wastewater and flocculant. After agitation, the pump 5 is started to pump the wastewater into the sedimentation tank 3. Once the wastewater is completely in the sedimentation tank 3, wastewater and flocculant continue to be added to the mixing tank 2 through the inlet pipe 6 for further mixing. Simultaneously, the second motor 84 is started to lower the vertical rod 82 and the filter plate 7. The flocculants in the wastewater settle rapidly under the interception of the filter plate 7. After the filter plate 7 reaches its bottom limit, the valve on the drain pipe 9 is opened first to discharge the wastewater above, followed by the valve on the sewage pipe 10 to discharge the settled flocculants. Finally, the second motor 84 is started to move the filter plate 7 back up to its original position, preparing for the next sedimentation operation. This equipment separates mixing and sedimentation, and utilizes the filter plate 7 to accelerate sedimentation, thereby improving wastewater treatment efficiency.
