Description

Technical Field

[0001] The utility model relates to the technical field of defoaming devices, and particularly relates to a defoaming device for wastewater in leachate treatment. Background Art

[0002] Landfill sites, waste incineration plants and other places will produce landfill leachate. The treatment methods of landfill leachate include physical and chemical methods and biological methods. When treating leachate in a reaction tank, foam is easily generated. When a large amount of foam accumulates on the water surface, it will affect the treatment of leachate.

[0003] For example, the Chinese utility model patent with the patent publication number CN219823742U includes a pool body. Two sets of rotating frames are arranged at the top of the pool body. Reciprocating lead screws are respectively rotatably connected to the two sets of rotating frames. A moving seat is threadedly sleeved between the two reciprocating lead screws. Two sliding rods are sleeved on the moving seat. The bottom ends of the two sliding rods extend into the inner cavity of the pool body and are fixedly connected with air bags. An installation plate is arranged inside the bottom ends of the two sliding rods.

[0004] This patent can use leachate to support the air bag to ensure that the bubble suction cover is always above the foam when the amount of leachate in the inner cavity of the pool body is different. In addition, a water pump is used to make the bubble suction cover generate suction to pump the foam in the inner cavity of the pool body into the inner cavity of the filter box, and the filter cotton is used to intercept the foam in the inner cavity of the filter box, realizing the function of defoaming leachate with different water volumes. However, when adding defoaming agent to the inside of the pool body, the motor needs to be started separately, and the steps are more. Moreover, the two motors also increase the production cost of the overall defoaming device. In view of this, we have proposed a defoaming device for wastewater in leachate treatment. Content of the Utility Model

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a defoaming device for wastewater in leachate treatment, which can solve the problems of separate startup and more steps when adding defoaming agent.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An antifoaming device for wastewater in leachate treatment, comprising a pool body. The left and right side surfaces of the pool body are respectively fixedly connected with storage boxes. The left and right side surfaces of the pool body are respectively provided with through grooves extending into its interior. The adjacent side surfaces of the two storage boxes are respectively fixedly connected with feeding boxes.

The adjacent side surfaces of the two feeding boxes are respectively provided with telescopic grooves. Springs are fixedly connected to the inner walls of the two telescopic grooves. The adjacent side surfaces of the two springs are respectively fixedly connected with telescopic plates. The rear side surfaces of the two telescopic plates are both inclined. An L-shaped groove is provided inside the feeding box. The lower side of the L-shaped groove extends out of the lower side surface of the feeding box. The L-shaped groove communicates with the interior of the storage box. A blanking component is arranged on the telescopic plate.

[0007] Preferably, the blanking component includes two moving plates, which are respectively fixedly connected to the opposite side surfaces of the two telescopic plates. Receiving grooves are respectively provided on the opposite inner walls of the two L-shaped grooves. The moving plates are adapted to the receiving grooves. A blanking port is provided on the upper surface of the moving plate. The lower side of the blanking port extends out of the lower side surface of the moving plate.

[0008] Preferably, a feeding hopper is provided on the upper surface of the storage box, and an antifoaming device is provided on the upper surface of the pool body.

[0009] Preferably, a motor is provided on the front side of the pool body. The output end of the motor is fixedly connected with a transmission shaft. Two first belt pulleys are sleeved on the outer surface of the transmission shaft.

[0010] Preferably, stirring shafts are fixedly connected to the front and rear inner walls of the pool body. The front end of the stirring shaft is fixedly connected with a driving shaft.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] (1) The defoaming device for wastewater in the leachate treatment first stores the antifoaming agent in the storage box. Then, when there is a lot of foam inside the pool body, the defoaming device is used to perform defoaming treatment. When the defoaming device moves to the front, it will contact the rear inclined surface of the telescopic plate, and then use the inclined surface to push the telescopic plate to move horizontally. When the telescopic plate moves, it will simultaneously compress the spring and drive the feeding component to move. After the feeding component moves, the antifoaming agent inside the storage box is released into the pool body through the L-shaped groove. Through the above structure, when the defoaming work is carried out on the inside of the pool body, the antifoaming agent can be automatically released into the inside of the pool body when the defoaming is completed, thereby reducing the frequency of subsequent foam generation inside the pool body and reducing the overall workflow during defoaming without starting the release device separately.

[0016] (2) The defoaming device for wastewater in the leachate treatment uses a motor in conjunction with a transmission shaft to drive two first pulleys to rotate. When the two first pulleys rotate, they will synchronously cooperate with two belts to drive two second pulleys to rotate, and then the two second pulleys are used to cooperate with two drive shafts to drive the stirring shaft to rotate, and the stirring shaft is used to drive the stirring blades to rotate. The stirring blades are used to allow the anti-foaming agent to be fully mixed with the permeate. Through the above structure, after the anti-foaming agent is added, the stirring blades can be used to mix the anti-foaming agent with the permeate, thereby increasing the effectiveness speed and ensuring the uniformity of the mixing.
