Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment in thermal power plants, and particularly relates to an ecological wastewater treatment device for thermal power plants. Background Art

[0002] The wastewater of a thermal power plant can be purified by an ecological treatment method. As the name implies, ecological water treatment is to carry out water treatment in an original ecological way, that is, to simulate producers, consumers, and decomposers in nature, and to make a careful and reasonable configuration, so that the entire food chain becomes richer and the ecological system becomes more stable, and the self-purification function of nature itself is used to achieve the purpose of purifying water quality.

[0003] After the conventional water tank is used for a long time, the sludge inside it accumulates too thickly and needs to be dug out manually, resulting in the problem that it is difficult to clean the sludge in the conventional water tank.

[0004] Therefore, we propose an ecological wastewater treatment device for thermal power plants to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that it is difficult to clean the sludge in the conventional water tank, and to propose an ecological wastewater treatment device for thermal power plants.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An ecological wastewater treatment device for thermal power plants includes a water tank. A sludge discharge pipe is fixedly connected to the side of the water tank. The internal space of the sludge discharge pipe is communicated with the internal space of the water tank. A screw rod is movably inserted into the sludge discharge pipe. A sludge discharge groove is fixedly sleeved on the upper part of the sludge discharge pipe. A fixing frame is fixedly connected to the sludge discharge groove. A reduction motor is fixedly connected to the fixing frame. The rotor of the reduction motor is fixedly connected to the screw rod. After sludge is formed in the water tank, it enters the sludge discharge pipe. The reduction motor is used to drive the screw rod to rotate, and the sludge is taken out by the screw rod, so that the sludge enters the sludge discharge groove and is discharged out through the sludge discharge groove, which is convenient for reducing the amount of sludge in the water tank.

[0008] Preferably, a support frame is fixedly connected to the lower end of the water tank. The support frame is used to level the inclination under the water tank and reduce the leveling difficulty of burying the water tank.

[0009] Preferably, a reinforcing rod is fixedly connected between the fixing frame and the sludge discharge groove. The reinforcing rod is used to increase the stability of the fixing frame in a standing state.

[0010] Preferably, the water tank includes a pool wall and an inclined bottom plate, and the inclined bottom plate is fixedly connected to the lower part of the pool wall. When a large amount of sludge is formed on the inclined bottom plate, the sludge is discharged to the side along the inclined bottom plate, which is convenient for the sludge to concentrate on the side.

[0011] Preferably, the sludge discharge pipe includes a pipe body, and a sludge inlet is provided at the lower part of the pipe body. The sludge can enter the pipe body conveniently through the sludge inlet.

[0012] Preferably, the sludge discharge trough includes a sludge guiding plate and a sludge retaining plate, and the sludge retaining plates are symmetrically and fixedly connected to the side ends of the sludge guiding plate. After the sludge is discharged between the sludge guiding plate and the sludge retaining plate, the sludge is discharged downward along the sludge guiding plate, which is convenient for guiding the sludge to be discharged.

[0013] Preferably, the sludge discharge trough further includes a reinforcing plate, and the reinforcing plate is fixedly connected to the lower end of the sludge guiding plate. The fixing range between the sludge discharge trough and the water tank is increased by using the reinforcing plate, and the stability of the sludge discharge trough is improved.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] 1. After the sludge is formed in the water tank, it enters the sludge discharge pipe. The reduction motor drives the screw rod to rotate, and the sludge is carried out by the screw rod, so that the sludge enters the sludge discharge trough and is discharged out through the sludge discharge trough, which is convenient for reducing the amount of sludge in the water tank.

[0016] 2. When a large amount of sludge is formed on the inclined bottom plate, the sludge is discharged to the side along the inclined bottom plate, which is convenient for the sludge to concentrate on the side.

[0017] 3. After the sludge is discharged between the sludge guiding plate and the sludge retaining plate, the sludge is discharged downward along the sludge guiding plate, which is convenient for guiding the sludge to be discharged. BRIEF DESCRIPTION OF THE DRAWINGS
