The debris and floating objects entering the treatment tank will accumulate on the top of the wastewater inside the treatment tank, affecting the combination effect of the chemical agents and wastewater inside the treatment tank, resulting in insufficient mixing of the treatment agent and wastewater, and may cause blockage of the internal pipes of the treatment tank. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that chemical wastewater entering the treatment tank will carry a lot of debris and floating objects. The debris and floating objects will accumulate on the top of the wastewater inside the treatment tank after entering the treatment tank, affecting the combination effect of the chemical agents and wastewater inside the treatment tank, resulting in insufficient mixing of the treatment agent and wastewater, and may cause blockage of the internal pipes of the treatment tank. A fine chemical wastewater treatment device is proposed.

[0005] The filter device of claim 1, wherein the filter device comprises a first motor, and a second motor is mounted on the filter screen, wherein the first motor is mounted on the filter screen, and the filter screen is located adjacent the filter screen.

When the treatment device is working, the wastewater enters the pool body through the water inlet groove at one end of the pool body. When the wastewater passes through the mesh plate, the filter screen on the surface of the mesh plate can block the floating objects in the wastewater, so that the wastewater passes through the filter screen and enters the pool body. At the same time, the first motor can be operated to drive the rotating shaft to rotate, and the scraper is driven to rotate through the rotating shaft. When the scraper rotates to the side close to the mesh plate, the floating objects in the wastewater will be pushed to the surface of the mesh plate to the output groove, and enter the interior of the collection box through the output groove. The floating objects are collected by the collection box, and the wastewater will enter the pool body through the filter screen at the bottom of the collection box. When the wastewater treatment device is not in use, the collection box can be pulled out to remove the collection box to clean the floating objects inside.

[0007] Preferably, the outer surface of the scraper is conical, and the thickness of the end of the scraper away from the rotating shaft is smaller than the thickness of the end close to the rotating shaft.

[0008] The effect achieved by the above components is: by setting the thickness of the scraper away from the rotating shaft to be smaller than the thickness of the end close to the rotating shaft, when the scraper pushes the floating objects toward the output trough, the floating objects are less likely to move toward the rotating shaft on the surface of the scraper, causing the floating objects to accumulate on the surface of the scraper.

[0009] Preferably, one end of the collecting box is fixedly connected to two supporting rods, and the sides of the two supporting rods close to each other are rotatably connected to moving wheels.

[0010] The effect achieved by the above components is that when the collection box is pulled away from the pool body, the moving wheel will move on the ground, and the support rod will support the end of the collection box away from the pool body, thereby avoiding the angle of the collection box away from the pool body from being deflected as much as possible.

[0011] Preferably, two oblique rods are fixedly connected to both sides of the inner wall of the pool body, and one end of the oblique rod away from the pool body is fixedly connected to the bottom end of the rectangular rod.

[0012] The effect achieved by the above components is: by setting the inclined rod, the bottom of the rectangular rod can be supported, the stability of the connection between the rectangular rod and the inner wall of the pool body can be improved, and the rectangular rod can be prevented as much as possible from bearing the weight of the collection box and causing deformation and fracture at the connection with the pool body.

[0013] Preferably, a rectangular piece is fixedly connected to one side of the scraper, and the rectangular piece is a rubber piece made of rubber material.

[0014] The effect achieved by the above components is that when the scraper pushes the floating objects on one side of the screen to the output slot, the surface of the screen can be further scraped and cleaned by the rubber rectangular piece, thereby improving the scraper's pushing effect on the floating objects.

[0015] Preferably, a pull rod is fixedly connected to one side of the collection box, and the cross-section of the pull rod is U-shaped.

[0016] The effect achieved by the above components is that by holding the outer surface of the U-shaped pull rod, the collection box can be pulled or pushed more conveniently to control the moving position of the collection box.

[0017] Preferably, a stirring device is provided on the top side of the pool body, and the stirring device includes a shaft, and the upper and lower ends of the shaft are respectively rotatably connected to the inner wall of the pool body. A second motor is provided on the top side of the pool body, and the output end of the second motor is fixedly connected to the top of the shaft, and a push plate is fixedly connected to the outer surface of the shaft, and a rectangular frame is threadedly connected to the outer surface of the shaft, and the bottom end of the rectangular frame rotates at the bottom end of the inner wall of the pool body.

[0018] The effect achieved by the above components is: after the wastewater enters the pool body, the second motor can be operated to drive the shaft to rotate, and the push plate can be driven to rotate slowly through the shaft. At the same time, the rectangular frame will rotate on the outside of the shaft, and the push plate on the outer surface of the rectangular frame and the shaft will slowly push and stir the wastewater inside the pool body, so that the wastewater treatment agent and wastewater can be mixed more comprehensively, thereby improving the wastewater treatment effect.

[0019] Preferably, a plurality of through grooves are provided on the outer surface of the push plate, and the through grooves are linearly distributed on the outer surface of the push plate.

[0020] The effect achieved by the above components is that when the push plate and the rectangular frame overlap, wastewater can pass through the through groove, and the overlap of the push plate and the rectangular frame can be avoided as much as possible to prevent wastewater from splashing out of the pool body.
