Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a reaction sedimentation device for wastewater treatment. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and achieve wastewater recycling and reuse, thus making full use of water resources. Commonly used agents in wastewater treatment include flocculants, coagulants, and conditioning agents. Wastewater treatment also uses sedimentation devices to precipitate impurities from the wastewater.

[0003] Existing reaction sedimentation devices for wastewater treatment have limited functionality and cannot heat the wastewater in the reaction sedimentation tank, resulting in insufficient reaction between the flocculant and the wastewater. This leads to slow aggregation of colloidal or flocculent precipitates, affecting the sedimentation efficiency during wastewater treatment. Based on this, this invention designs a reaction sedimentation device for wastewater treatment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a reaction sedimentation device for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reaction sedimentation device for wastewater treatment includes a reaction sedimentation tank, a water storage tank, a filter screen, and a heat-conducting pipe. The water storage tank is located at the bottom of the reaction sedimentation tank. A stirring assembly is installed on the reaction sedimentation tank. A water inlet is opened on the front side of the reaction sedimentation tank. The filter screen is fixedly installed inside the water inlet. A sealing plate slides through the reaction sedimentation tank on the side near the water inlet. A water pump is fixedly installed on the reaction sedimentation tank via a first side seat. A pumping pipe is fixedly connected between the reaction sedimentation tank and the inlet of the water pump. A water inlet pipe is fixedly connected between the heat-conducting pipe and the outlet of the water pump. One end of the water inlet pipe is fixedly connected to a return pipe. One end of the return pipe is located above the reaction sedimentation tank. An electric heating sleeve is fixedly fitted on the outside of the heat-conducting pipe. A protective sleeve is fixedly installed on the reaction sedimentation tank via a second side seat. Both the heat-conducting pipe and the electric heating sleeve are located inside the protective sleeve.

[0007] As a preferred embodiment of this utility model, the stirring assembly includes an electric push rod, a stirring motor, and a rotating shaft. The electric push rod is fixedly installed on the upper end of the reaction sedimentation tank via a bracket. The stirring motor is fixedly installed on the telescopic end of the electric push rod via a carrier. The rotating shaft is fixedly connected to the drive end of the stirring motor. Several stirring blades are fixedly connected at intervals on the rotating shaft.

[0008] As a preferred embodiment of this utility model, a guide groove is provided on the inner side of the bracket, and the carrier is slidably connected to the guide groove.

[0009] As a preferred embodiment of this utility model, a handle is fixedly installed at the upper end of the sealing plate, and the cross-sectional shape of the sealing plate is an inverted U-shape.

[0010] As a preferred technical solution of this utility model, a sewage outlet is provided on the rear side of the reaction sedimentation tank, and a sealing door for sealing the sewage outlet is movably hinged on the reaction sedimentation tank. A side block is fixedly installed on the outside of the sewage outlet, and a T-shaped stud is threadedly connected between the sealing door and the side block.

[0011] As a preferred embodiment of this utility model, a drain pipe is fixedly connected to the front side of the water storage tank, and a switch valve is provided on the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses an electric push rod to drive the carrier to descend, causing the rotating shaft and stirring blades to extend into the reaction sedimentation tank. A stirring motor drives the rotating shaft to rotate, which can stir the flocculant and wastewater in the reaction sedimentation tank. A water pump can pump the wastewater in the reaction sedimentation tank to the heat-conducting pipe through the pumping pipe and the inlet pipe. The wastewater finally flows back to the reaction sedimentation tank through the return pipe. The electric heating sleeve transfers heat to the heat-conducting pipe, thereby heating the wastewater passing through the heat-conducting pipe. This allows the wastewater in the reaction sedimentation tank to be circulated and heated during stirring, promoting a full reaction between the flocculant and the wastewater, accelerating the agglomeration speed of colloidal or flocculent precipitates, and improving the sedimentation efficiency during wastewater treatment.

[0020] like Figures 1 to 4 As shown, this utility model provides a reaction sedimentation device for wastewater treatment, including a reaction sedimentation tank 1, a water storage tank 2, a filter screen 3, and a heat conduction pipe 603. The water storage tank 2 is located at the bottom of the reaction sedimentation tank 1. A stirring assembly is installed on the reaction sedimentation tank 1. A water inlet 4 is opened on the front side of the reaction sedimentation tank 1. The filter screen 3 is fixedly installed in the water inlet 4. A sealing plate 5 slides through the reaction sedimentation tank 1 on the side near the water inlet 4. A water pump 6 is fixedly installed on the reaction sedimentation tank 1 through a first side seat. A water pumping pipe 601 is fixedly connected between the reaction sedimentation tank 1 and the inlet end of the water pump 6. The heat conduction pipe 603... A water inlet pipe 602 is fixedly connected between the outlet end of the water pump 6 and the outlet end of the water pump 6. One end of the water inlet pipe 602 is fixedly connected to the return pipe 604. One end of the return pipe 604 is located above the reaction sedimentation tank 1. The water pump 6 can pump the wastewater in the reaction sedimentation tank 1 into the heat conduction pipe 603 through the pump pipe 601 and the water inlet pipe 602. The wastewater finally flows back into the reaction sedimentation tank 1 through the return pipe 604. An electric heating sleeve 8 is fixedly sleeved on the outside of the heat conduction pipe 603. A protective sleeve 7 is fixedly installed in the reaction sedimentation tank 1 through the second side seat. Both the heat conduction pipe 603 and the electric heating sleeve 8 are located inside the protective sleeve 7.

[0021] Among them, such as Figure 1As shown, the stirring assembly includes an electric push rod 102, a stirring motor 103, and a rotating shaft 104. The electric push rod 102 is fixedly installed on the upper end of the reaction sedimentation tank 1 via a bracket 101. The stirring motor 103 is fixedly installed on the telescopic end of the electric push rod 102 via a carrier 106. The rotating shaft 104 is fixedly connected to the drive end of the stirring motor 103. Several stirring blades 105 are fixedly connected at intervals on the rotating shaft 104. The electric push rod 102 drives the carrier 106 to descend, causing the rotating shaft 104 and the stirring blades 105 to extend into the reaction sedimentation tank 1. The stirring motor 103 drives the rotating shaft 104 to rotate, which can stir and treat the flocculant and wastewater in the reaction sedimentation tank 1.

[0022] Among them, such as Figure 1 As shown, a guide groove 107 is provided on the inner side of the bracket 101, and the carrier 106 is slidably connected to the guide groove 107, so as to achieve the purpose of providing good guidance when the carrier 106 is raised and lowered.

[0023] Among them, such as Figure 1 As shown, a handle 501 is fixedly installed on the upper end of the sealing plate 5. The cross-sectional shape of the sealing plate 5 is an inverted U-shape, which facilitates the extraction of the sealing plate 5 along the reaction sedimentation tank 1.

[0024] Among them, such as Figure 3 and Figure 4 As shown, a drain outlet 108 is provided on the rear side of the reaction sedimentation tank 1. A sealing door 9 for sealing the drain outlet 108 is movably hinged on the reaction sedimentation tank 1. A side block 1081 is fixedly installed on the outside of the drain outlet 108. A T-shaped stud 901 is threaded between the sealing door 9 and the side block 1081, so as to achieve the purpose of locking and fixing the sealing door 9.

[0025] Among them, such as Figure 1 As shown, a drain pipe 201 is fixedly connected to the front side of the water storage tank 2. A switch valve 202 is installed on the drain pipe 201. When the switch valve 202 is opened, the water that is full in the water storage tank 2 can be discharged in a concentrated manner.

[0026] The working principle of this utility model:

[0027] During operation, wastewater is discharged into the reaction sedimentation tank 1, and an appropriate amount of flocculant is added. The electric push rod 102 drives the carrier 106 to descend, causing the rotating shaft 104 and stirring blades 105 to extend into the reaction sedimentation tank 1. The stirring motor 103 drives the rotating shaft 104 to rotate, thus mixing the flocculant and wastewater in the reaction sedimentation tank 1. A water pump 6 pumps the wastewater from the reaction sedimentation tank 1 through the pumping pipe 601 and the inlet pipe 602 to the heat-conducting pipe 603. The wastewater ultimately flows back into the reaction sedimentation tank 1 through the return pipe 604. The electric heating sleeve 8 transfers heat to the heat-conducting pipe 603, thereby heating the wastewater passing through the heat-conducting pipe 603, thus improving the reaction sedimentation tank's performance. The wastewater undergoing stirring in the reaction sedimentation tank 1 is circulated and heated to promote a full reaction between the flocculant and the wastewater, accelerating the settling speed of colloidal or flocculent precipitates. After settling, the sealing plate 5 is lifted out along the reaction sedimentation tank 1 using the handle 501. The water in the reaction sedimentation tank 1 is filtered through the filter screen 3 and then flows into the storage tank 2 for storage. The switch valve 202 is opened to discharge the water that is full in the storage tank 2. If it is necessary to clean the sediment in the reaction sedimentation tank 1, the electric push rod 102 is used to drive the carrier 106 to rise and reset, making room for personnel to clean. The sealing door 9 is opened, and the sediment in the reaction sedimentation tank 1 is discharged out through the drain outlet 108.
