Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment tank. Background Art

[0002] In order to prevent direct discharge of sewage from polluting the environment, it is usually necessary to treat the sewage before discharging it. In order to facilitate the treatment of sewage, the staff usually use a sewage treatment tank. The existing sewage treatment tank is usually composed of a tank body, a filter plate and a stirring mechanism.

[0003] For example: The utility model with application number 201922383330.4 discloses a sewage treatment tank, which specifically includes a tank body, wherein the top of the tank body is fixedly connected with a slide rail, and the inside of the slide rail is slidably connected with a movable box, and the inner bottom wall of the slide rail is provided with a through groove, which passes through the top of the tank body and extends to the inside of the tank body, and the inner top wall of the movable box is movably connected with a rotating rod. The sewage treatment tank is driven by starting a rotating motor to drive the half-face gear to rotate. When the half-face gear is meshed with the reverse bevel gear, the driving rod rotates counterclockwise. Through the connection between the gear and the rack plate, the stirring blade moves to the right during the counterclockwise stirring process. When the half-face gear is meshed with the forward bevel gear, the driving rod rotates clockwise, so that the stirring blade moves to the left during the clockwise stirring process. Through the continuous rotation of the rotating motor, the stirring blade reciprocates left and right during the stirring process to fully mix the sewage and the remover to prevent the occurrence of eddy currents that affect the mixing.

[0004] However, as far as the current traditional sewage treatment tank is concerned, after the sewage is poured into the sewage treatment tank, the sewage will first pass through the filter plate to separate the impurities and particulate matter in the sewage. However, during long-term use, the impurities and particulate matter separated by the filter plate will gradually accumulate on the filter plate, which can easily cause blockage of the filter plate, hinder the normal filtration of the sewage, and affect the sewage treatment efficiency of the sewage treatment tank. Utility Model Content

[0005] In view of this, the utility model provides a sewage treatment tank, which is provided with a cleaning rack and an extended cleaning block that can automatically clean the impurities and particulate matter separated on the filter plate. During the rotation of the mixing paddle, the second extrusion block will be driven to rotate through the connecting disk, and during the rotation of the second extrusion block, the first extrusion block will be intermittently squeezed. After the first extrusion block is squeezed, it will drive the sliding block to slide along the fixed column. During the sliding of the sliding block, the first connected swing arm will be driven to swing, and as the first connected swing arm swings, the sliding seat will be driven to slide in the second connected swing arm, and the second connected swing arm will be unfolded by the sliding of the sliding seat. When the second extrusion block is away from the first extrusion block, the sliding block will automatically reset under the action of gravity. During the unfolding of the second connected swing arm, the cleaning rack will be driven to move by the control swing arm, and as the cleaning rack moves, the extended cleaning block will be driven to move, and then the impurities and particulate matter separated on the separation filter plate will be cleaned through the movement of the cleaning rack and the extended cleaning block.

[0012] Beneficial Effects

[0013] During the use of the utility model, in the process of mixing sewage and flocculant, as the mixing paddle rotates, the second extrusion block will intermittently extrude the first extrusion block, and then the two cleaning frames will intermittently move through a series of transmissions, and at the same time, the cooperation of the extended cleaning block and the return spring can make the extended cleaning block extend and retract along the inner wall of the treatment tank body during the sliding of the cleaning frame, thereby ensuring the normal sliding of the cleaning frame, and the movement of the cleaning frame and the extended cleaning block can automatically clean the impurities and particulate matter separated on the separation filter plate, preventing the impurities and particulate matter from accumulating on the separation filter plate, thereby ensuring the separation effect of the separation filter plate on sewage, improving the sewage treatment efficiency of the sewage treatment tank, effectively improving the practicability of the sewage treatment tank, and making it more convenient to use.

[0014] The sealing plate is set to seal the discharge chute when there is no need to discharge impurities and particulate matter. When the discharge chute is discharging, the discharged impurities and particulate matter will flip the sealing plate, so that the impurities and particulate matter can be smoothly discharged into the collection box for collection. The activated carbon block is set to adsorb and purify the odor of the sewage in the treatment tank to prevent the odor from emitting into the outside air and polluting the surrounding air.
