Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency sedimentation tank with sludge thickening function and micro-sand loading. Background Art

[0002] The high-efficiency sedimentation tank with micro-sand loading is a technology used to improve the sedimentation efficiency in sewage treatment. It enhances the sedimentation effect of suspended substances and colloidal substances by adding fine sand particles (usually sand particles with a diameter of 0.1 - 0.4 mm) into the sedimentation tank. At present, when the high-efficiency sedimentation tank with micro-sand loading is in use, a coagulant and a flocculant are added into the tank for stirring and mixing. The sediment attached to the fine sand particles has a high water content, occupies a large space, and directly discharging it will also affect the water purification rate. In view of the above problems, the present utility model document proposes a high-efficiency sedimentation tank with micro-sand loading and sludge thickening function. Content of the Utility Model

[0003] The utility model provides a high-efficiency sedimentation tank with micro-sand loading and sludge thickening function, which solves the disadvantages in the prior art that when the high-efficiency sedimentation tank with micro-sand loading is in use, a coagulant and a flocculant are added into the tank for stirring and mixing, the sediment attached to the fine sand particles has a high water content, occupies a large space, and directly discharging it will also affect the water purification rate.

[0004] The utility model provides the following technical solutions:

[0005] A high-efficiency sedimentation tank with micro-sand loading and sludge thickening function, comprising:

[0006] A reaction tank, one side of the reaction tank is communicated with an access pipe for conveying sewage, a corresponding first control valve is arranged on the access pipe, a cross plate is arranged above the reaction tank, a transmission rod is rotatably installed at the center of the bottom of the cross plate, a sector-shaped stirring blade for stirring and mixing the coagulant, flocculant, micro-sand and sewage is fixedly arranged at the bottom end of the transmission rod, a water pump is fixedly installed on the top of the cross plate, a liquid suction pipe at the input end of the water pump extends into the reaction tank, and the other end of the conveying pipe at the output end of the water pump is connected to a compression tank;

[0007] A fixing component, arranged on the top of the reaction tank, for conveniently installing the cross plate for equipment maintenance;

[0008] A compression and filtration component, arranged on the compression tank, for reducing the water content of the sediment attached to the micro-sand.

[0009] In a possible design, the fixing component includes two I-shaped supports symmetrically and fixedly arranged on the top of the reaction tank, a notch for clamping the cross plate is arranged on the top of the I-shaped support, and two limiting plates for improving the clamping stability are symmetrically and fixedly arranged at the bottom of the cross plate.

[0010] In a possible design, the compression and filtration component includes a U-shaped frame fixedly arranged on the top of the compression tank. A central part at the bottom of the U-shaped frame is fixedly installed with an electric push rod. The output end of the electric push rod is fixedly provided with a pressing plate adapted to the size of the tank opening of the compression tank. A sewage collection box equipped with a filter screen and a filter element is slidably installed in a chute on one side of the compression tank. Two grips are symmetrically and fixedly arranged on the outer side of the sewage collection box.

[0011] In a possible design, a water receiving tank is fixedly arranged at the bottom of the compression tank. A drain pipe is communicated with one side of the water receiving tank, and a corresponding second control valve is arranged on the drain pipe.

[0012] In a possible design, the sewage collection box and the compression tank are fixed by the same bolt.

[0013] In a possible design, the top end of the transmission rod penetrates through the top of the cross plate and is fixedly provided with a first bevel gear. The rotating shaft of the water pump extends outside the water pump and is fixedly connected with a second bevel gear, and the second bevel gear meshes with the first bevel gear.

[0014] It should be understood that the above general description and the following detailed description are only exemplary and cannot limit the present utility model.

[0015] The working principle and usage process of this technical solution are as follows:

[0016] During use, open the first control valve, and input the sewage to be treated into the reaction tank through the access pipe. At the same time, add appropriate amounts of coagulant, flocculant and fine sand into the reaction tank, and start the water pump. The rotating shaft of the water pump drives the second bevel gear to rotate. Since the second bevel gear meshes with the first bevel gear, it further drives the transmission rod and the sector-shaped stirring blade to rotate. The sector-shaped stirring blade rapidly stirs in the reaction tank, so that the coagulant, flocculant, fine sand and sewage are fully mixed to form larger flocs and adhere to the fine sand.

[0017] After a period of stirring and reaction, the sediment adhering to the fine sand increases. The water pump conveys the mixed liquid containing fine sand and sediment to the compression tank through the liquid extraction pipe and the conveying pipe. In the compression tank, the electric push rod makes the pressing plate move downward to compress the sludge in the mixed liquid and reduce its moisture content. The clear water generated during the compression process is further purified through the filter screen and filter element of the sewage collection box and then discharged into the water receiving tank. Open the second control valve to discharge the sewage in the water receiving tank through the drain pipe. Regularly open the bolt between the sewage collection box and the compression tank, take out the sewage collection box, and clean the sludge and impurities therein.

[0018] The present utility model has the following beneficial effects:

[0019] This utility model compresses sludge by using a compression and filtration component, significantly reducing the moisture content of the sludge and reducing the difficulty and cost of subsequent treatment. Through the design of the fixing component, the cross plate can be conveniently installed and disassembled, facilitating the maintenance and repair of the inside of the reaction tank.
