Description

Technical Field

[0001] This utility model relates to a sewage treatment tank for sewage treatment, belonging to the field of sewage treatment technology. Background Technology

[0002] Wastewater generally refers to wastewater discharged from domestic and industrial processes that has been polluted to a certain extent. Wastewater mainly includes domestic sewage, industrial wastewater, and initial rainwater. The main pollutants in wastewater include pathogens, oxygen-consuming pollutants, plant nutrients, and toxic pollutants. Wastewater is ubiquitous in daily life, so it is necessary to use wastewater treatment ponds to treat it.

[0003] The existing patent number CN218221307U describes a wastewater treatment tank. This device features a top plate with unclogging rods on its upper surface, corresponding to through holes in the filter plate surface. When the top plate moves upward, it facilitates unclogging of the filter plate, preventing contaminants from blocking it and improving efficiency. Furthermore, a bevel gear on the outer edge of a threaded sleeve meshes with the shaft end, allowing the top plate to reciprocate up and down using a drive motor to clear the through holes in the filter plate. While practical, this device does not pre-filter large impurities; instead, it uses a crushing method. This increases the difficulty of treating subsequent flocculants and affects the recovery of large impurities. Additionally, the device lacks a surface cleaning structure, resulting in some flocculants adhering to the surface during wastewater treatment, impacting the quality of subsequent wastewater treatment.

[0004] The purpose of this utility model is to provide a sewage treatment tank for sewage treatment, so as 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 wastewater treatment tank includes a main body, an inlet tank, and a retaining frame. The inlet tank is fixedly connected to the upper front side of the main body. An inlet filter is fixedly connected to the rear side of the inlet tank. A rotating scraper is rotatably connected to the front side of the inlet tank. A waste discharge box is sealed to the lower end of the inlet tank. A waste discharge wheel is rotatably connected to the lower side of the waste discharge box.

An adjusting frame is slidably connected to the middle position of the lower side of the rear wall of the retaining frame. A limiting roller is rotatably connected to the inner side of the adjusting frame. The limiting roller is rotatably connected to the main body of the treatment tank.

[0007] Furthermore, a water inlet pipe is sealed and connected at the middle of the upper end of the water inlet tank, and a water guide pipe is sealed and connected at the lower rear end of the water inlet tank.

[0008] Furthermore, a first motor is fixedly connected to the front end of the water inlet tank, the output shaft of the first motor is fixedly connected to the rotating scraper, and a brush is fixedly connected to the rear end of the rotating scraper, with the brush slidably connected to the water inlet filter screen.

[0009] Furthermore, a slow-speed motor is fixedly connected to the right end of the waste discharge box, and the output shaft of the slow-speed motor is fixedly connected to the waste discharge wheel. A waste discharge frame is sealed to the lower front end of the waste discharge box.

[0010] Furthermore, a second motor is fixedly connected to the upper left front side of the card frame, and a pulley assembly is fixedly connected to the lower end of the output shaft of the second motor. The left pulley of the pulley assembly is fixedly connected to the traveling roller, and the right pulley of the pulley assembly is fixedly connected to the cleaning roller brush.

[0011] Furthermore, an adjusting screw is spirally connected to the lower rear end of the card frame, the adjusting screw is rotatably connected to the adjusting frame, and a turntable is fixedly connected to the rear end of the adjusting screw.

[0012] Furthermore, a limiting groove is formed on the upper side of the outer wall of the main body of the treatment pool.

[0013] The beneficial effects of this utility model are:

[0014] This utility model incorporates an inlet pipe to inject wastewater into an inlet tank. An inlet filter screen removes non-flocculated impurities. A first motor rotates a scraper that drives a brush, discharging large particles from the wastewater and directing them into a discharge box. A slow-speed motor then rotates a discharge wheel to expel the filtered large particles through a discharge frame. This continuous process of removing impurities from the wastewater improves treatment efficiency. The device utilizes a clamping frame that can be clamped onto the upper wall of the treatment tank body. By rotating the turntable, the adjusting screw drives the adjusting frame to move, allowing the limiting roller to be clamped inside the limiting rail groove. The rotation of the second motor causes the traveling roller to rotate, enabling the clamping frame to move automatically around the upper edge of the treatment tank body. Through the pulley assembly, the cleaning roller rotates simultaneously, allowing it to automatically clean the inner wall of the treatment tank body. This improves the convenience of cleaning the inner wall of the sewage treatment tank and enhances the quality of subsequent sewage treatment. Attached Figure Description
