Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to a sedimentation tank for treating chemical wastewater. Background Art

[0002] At present, a Chinese utility model with the announcement number CN214734980U discloses a settling tank for treating wastewater in petrochemical industry, which relates to the technical field of wastewater treatment. The settling tank for treating wastewater in petrochemical industry comprises a first box, a second box is fixedly installed on one side outer wall of the first box, a third box is fixedly installed on the other side outer wall of the first box, a motor is fixedly installed on the top of the first box, a rotating rod is rotatably installed inside the first box, and the output shaft of the motor extends to the inside of the first box through a coupling and is fixedly connected to the rotating rod. The settling tank for treating wastewater in petrochemical industry accelerates the reaction speed of sewage and flocculant in the settling tank by stirring, so that water and sludge are separated and layered. The separated water is thrown out by the rotating stirring blades through centrifugal force. After the water passes through the osmotic membrane, the water quality of the water will be better, which saves time and improves the reaction efficiency compared with the reaction between sewage and flocculant.

[0003] Although the existing sedimentation tank is equipped with a stirring assembly, there are still other problems in use, such as poor stirring effect. The stirring assembly is connected to the mounting frame in a fixed connection manner, which leads to limitations in the stirring assembly. It can only be stirred at the center, and the wastewater on the side has poor fluidity with it, which increases the wastewater processing time and is inconvenient to clean the impurities at the bottom of the tank. In order to avoid excessive accumulation of impurities at the bottom of the tank, personnel are required to regularly clean it with handheld tools. Personnel need to enter the tank when cleaning, which increases the workload of personnel and has low practicality. In order to solve the above-mentioned problems, we propose a sedimentation tank for chemical wastewater treatment. Utility Model Content

[0004] The utility model aims to provide a sedimentation tank for treating chemical wastewater, which solves the problems that the internal stirring effect of the existing sedimentation tank is poor and it is inconvenient to clean the impurities at the bottom of the tank.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a sedimentation tank for chemical wastewater treatment, including a tank body and a stirring mechanism, a mounting frame is welded on the top of the tank body, a reciprocating screw is rotatably connected to the inside of the mounting frame through a bearing, a second motor is fixedly sleeved on the other end of the reciprocating screw, a threaded plate is threadedly connected to the surface of the reciprocating screw, a fixing frame is installed on the bottom of the threaded plate, a threaded rod is rotatably connected to the inside of the tank body through a bearing, a third motor is fixedly sleeved on the other end of the threaded rod, a push plate is threadedly connected to the surface of the threaded rod, sewage outlets are opened on the front and back sides of the tank body, and baffles are bolted to the front and back sides of the tank body.

[0006] The above technical solution can achieve good stirring effect, improve the fluidity of the liquid in the pool, speed up the wastewater treatment efficiency, and at the same time facilitate the cleaning of impurities on the bottom of the pool. The operation is simple and labor-saving, which reduces the workload of personnel and is highly practical.

[0008] By adopting the above technical solution, through the arrangement of the first motor, the rotating rod and the stirring rod, the stirring rod can be driven to rotate after the first motor is started.

[0009] The utility model is further configured as follows: a slide rail is bolted inside the mounting frame, and a sliding block slidably connected to the slide rail is welded on the top of the threaded plate.

[0010] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from rotating during the left and right movement.

[0011] The utility model is further configured as follows: a limiting rod is provided through one side of the push plate, and both ends of the limiting rod are welded to the inside of the tank body.

[0012] By adopting the above technical solution, the push plate can be limited by setting the limit rod to prevent the push plate from turning over during the left and right movement.

[0013] The utility model is further configured as follows: a protective cover is bolted to one side of the pool body and the mounting frame.

[0014] By adopting the above technical solution and providing a protective cover, the second motor and the third motor can be protected to prevent the second motor and the third motor from being damaged by collision with foreign objects.

[0015] The utility model is further configured as follows: the reciprocating screw, the threaded plate, the threaded rod and the push plate are all made of stainless steel.

[0016] By adopting the above technical solution, the reciprocating screw, the threaded plate, the threaded rod and the push plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0017] The utility model is further configured as follows: scale lines are integrally punched inside the pool body.

[0018] By adopting the above technical solution, the staff can observe the amount of wastewater in the tank body conveniently through the setting of scale lines.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model first introduces wastewater into the pool body and puts in flocculant, and then starts the first motor and the second motor at the same time. After starting, the first motor will drive the rotating rod and the stirring rod to rotate, and the second motor will drive the reciprocating screw to rotate after starting. When the reciprocating screw rotates, it will drive the threaded plate and the fixed frame to move back and forth laterally, which can achieve a good stirring effect, improve the fluidity of the liquid in the pool, and accelerate the wastewater treatment efficiency.

[0021] 2. The utility model removes the baffle from the pool body after the wastewater is discharged, and starts the third motor after the baffle is removed. After starting, the third motor will drive the threaded rod to rotate. When the threaded rod rotates, it will drive the push plate to move to the left with the cooperation of the limit rod. When the push plate moves to the left, it will push the impurities to the sewage outlet, which can facilitate the cleaning of impurities on the bottom of the pool. The operation is simple and labor-saving, which reduces the workload of personnel and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
