Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a structure for a microbial sludge treatment tank. Background Technology

[0002] Sludge treatment is the process of reducing, stabilizing, and rendering harmless sludge. The higher the level of wastewater treatment, the more sludge residue will be generated and requires treatment. Unless land-based treatment or sewage ponds are used, most wastewater treatment plants must have sludge treatment facilities. For modern wastewater treatment plants, sludge treatment and disposal has become the most complex and costly part of the wastewater treatment system operation.

[0003] Existing sludge treatment processes often employ biological treatment, utilizing the metabolic functions of microorganisms to degrade and transform dissolved and colloidal organic pollutants in the sludge into harmless substances, thus purifying the sludge. During treatment, treatment tanks are frequently used, where the sludge undergoes filtration. During this process, some sludge adheres to the inner walls of the treatment tank. This adhering sludge can affect the reaction efficiency, and incomplete reaction followed by adhesion to the inner walls can also cause difficulties in subsequent cleaning and affect future use. Utility Model Content

[0004] The purpose of this invention is to provide a structure for a microbial sludge treatment tank for sludge treatment, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A microbial sludge treatment tank structure for sludge treatment includes a treatment tank body. A connecting bridge is provided at the top of the treatment tank body, and an installation platform is provided at one end of the connecting bridge. The installation platform is located in the middle of the treatment tank body. A drive motor is installed at the top of the installation platform, and the output shaft of the drive motor passes through the installation platform. A connecting rod is installed on the output shaft of the drive motor. A drive box is fixed to the bottom of the connecting rod. Two connecting rods are installed on the side wall of the drive box. A support plate is installed inside the drive box. One end of each connecting rod passes through the drive box and is fixedly connected to the support plate. A scraper is installed at the end of each connecting rod away from the drive box. The scraper cooperates with the inner wall of the treatment tank body. A stirring assembly for stirring the treatment tank body is also provided on each connecting rod.

[0007] Preferably, the stirring assembly includes a connecting sleeve rod and several stirring components. The connecting sleeve rod is sleeved on the outside of the second connecting rod and is rotatably engaged with the second connecting rod. One end of the connecting sleeve rod is connected to the drive box via a bearing. One end of the connecting sleeve rod is disposed inside the drive box. The drive box is provided with a drive assembly for rotating the connecting sleeve rod. Each of the stirring components is fixed on the outer wall of the two connecting sleeve rods.

[0008] Preferably, the drive assembly includes a first bevel gear and two second bevel gears. The first bevel gear and the two second bevel gears are rotatably disposed within the drive box. The second bevel gear is fixed on the connecting sleeve rod. A through hole is provided in the center of the second bevel gear. One end of the connecting sleeve rod passes through the through hole and is fixedly connected to the support plate. A support rod is fixed to the inner bottom of the treatment tank body. The drive box is rotatably disposed on the support rod. One end of the support rod passes through the drive box and is fixedly connected to the first bevel gear. The first bevel gear meshes with the two second bevel gears.

[0009] Preferably, the stirring component includes a connecting ring and multiple stirring rods, the connecting ring being fixed on the connecting sleeve rod, and each of the stirring rods being evenly distributed on the outer wall of the connecting ring.

[0011] Preferably, a drain pipe is installed on the bottom side wall of the treatment tank body, and an electromagnetic control valve is installed on the drain pipe.

[0012] Beneficial effects: During sludge treatment, the drive motor can be started, which drives connecting rod one, which in turn drives the drive box to rotate. The drive box, through the support plate, drives connecting rod two on both sides to rotate. The rotation of connecting rod two causes the scraper to scrape the sludge on the inner wall of the treatment tank. The scraper, with its rubber scraper strip, scrapes the sludge on the inner wall of the treatment tank, preventing sludge from adhering to the inner wall and affecting the reaction between sludge and microorganisms. It also prevents subsequent sludge from solidifying on the inner wall, causing inconvenience for subsequent cleaning. When the drive box and connecting rod one rotate, the drive assembly is also activated. The drive assembly drives the connecting sleeve rod outside connecting rod one to rotate, which in turn drives the agitator to rotate. This allows the agitator to stir the wastewater, thereby improving the mixing between sludge and microorganisms in the wastewater and increasing treatment efficiency. Attached Figure Description
