Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to sewage treatment equipment with a foam driving structure. Background Art

[0002] With the continuous acceleration of urbanization and the continuous innovation of various production enterprises' technologies, the current sewage treatment mode can be mainly divided into two modes: centralized treatment and decentralized treatment. Centralized treatment is applied to the treatment of urban population density and large-volume sewage. Regional decentralized sewage treatment is generally used for sewage treatment discharged from areas with relatively close geographical locations or that cannot be included in the urban sewage collection system.

[0003] Most equipment still has major shortcomings when it comes to biological phosphorus removal and biological nitrogen removal, resulting in excessive reliance on back-end biological treatment stages and chemical phosphorus removal, which in turn increases the operating costs of sewage treatment and indirectly leads to abnormal operation of water quality indicators of some equipment.

[0004] A patent document with publication number CN220334961U discloses a sewage treatment equipment with a denitrification function. By fixing a stirring box in a denitrification tank and stirring and mixing the agent with the liquid in the stirring box, the decomposition of the agent can be accelerated and the agent precipitation can be prevented to affect the denitrification effect. Then the pipeline is connected to the aeration pipe. During aeration, the agent mixture can be sprayed out by an aeration nozzle, which can increase the spray range of the agent and make it easier for the agent to react with the sewage in the denitrification tank, thereby improving the denitrification effect. By fixing a rotating blade at the bottom of the stirring rod and arranging the rotating blade at the outlet position of the liquid inlet pipe, when the sewage is sprayed out through the liquid inlet pipe, the rotating blade can be pushed to rotate, so that the stirring blade can be brought to stir in the stirring box, thereby improving the use effect.

[0005] However, the sewage treatment equipment with denitrification function will generate a large number of bubbles during the process of using chemicals to treat sewage. The bubbles stay on the surface of the sewage, resulting in uneven mixing of the sewage and subsequent treatment chemicals. Utility Model Content

An overflow pipe 5 is fixedly connected to the front of the sewage treatment tank 1. The partition 2 divides the internal atmosphere of the sewage treatment tank 1 into left and right parts. When there is too much sewage on the right side of the partition 2, the overflow pipe 5 allows the sewage to flow from the overflow pipe 5 to the left side of the sewage treatment tank 1. A drain pipe 3 is fixedly connected to the bottom of the right side of the sewage treatment tank 1.

[0029] The driving device includes a transmission unit and a defoaming unit. The transmission unit includes a motor 401, a screw rod 402, a screw nut 403, a bearing seat 404 and a movable plate 405. The motor 401 is installed on the left top of the sewage treatment tank 1. The motor 401 is a forward and reverse motor with a model of 3IK15RGN-C; 3GN90K. The screw rod 402 is connected to the output end of the motor 401, the screw nut 403 is connected to the outer surface of the screw rod 402, the bearing seat 404 is fixedly installed on the top of one side of the inner wall of the sewage treatment tank 1, and the movable plate 405 is fixedly connected to the screw rod nut. At the bottom of the mother 403, a through hole with a diameter larger than that of the screw rod 402 is provided on the top left side of the sewage treatment tank 1. The screw rod 402 passes through the through hole. A ball bearing is installed inside the bearing seat 404. One end of the screw rod 402 is connected to the inner ring of the ball bearing. A slide groove 6 is provided on one side of the inner wall of the sewage treatment tank 1. A slider 412 is slidably connected to the inner wall of the slide groove 6. The sewage treatment tank 1 is fixedly connected to one side of the movable plate 405. During the movement of the movable plate 405, the slider 412 will be driven to slide inside the slide groove 6, thereby ensuring the stable movement of the movable plate 405.

[0030] The defoaming unit includes a magnetic rack 406, a telescopic spring 407, a magnetic block 408, a gear 409, a rotating shaft 410, a driving plate 411 and a cleaning brush 413. The magnetic blocks 408 are fixedly installed on both sides of the top of the movable plate 405, the telescopic spring 407 is fixedly connected to the side where the two magnetic blocks 408 are close to each other, the magnetic rack 406 is fixedly connected to the end of the telescopic spring 407 away from the magnetic block 408, the gear 409 is meshingly connected to the side of the magnetic rack 406, the rotating shaft 410 is connected to the center of the gear 409, the cleaning brush 413 is connected to the bottom of the rotating shaft 410, the driving plate 411 is connected to the right side of the movable plate 405, and mounting holes are evenly spaced on the right side of the upper surface of the movable plate 405. Bearings are installed inside the mounting holes, and the rotating shaft 410 passes through the inner ring of the bearing. The magnetic rack 406 and the magnetic blocks 408 on both sides have the same magnetic poles on the side close to each other and repel each other. In the process of sewage treatment, the magnetic rack 406 can be pushed to Moving in the forward and backward directions, the magnetic rack 406 squeezes the telescopic spring 407 on one side. When the telescopic spring 407 is squeezed to the maximum compression amount, the magnetic rack 406 will be reset under the action of its own restoring force, thereby squeezing the telescopic spring 407 on the other side. During the movement of the magnetic rack 406, it will continuously approach and move away from the magnetic blocks 408 on both sides. Because the magnetic poles of the magnetic rack 406 and the magnetic blocks 408 on both sides are the same and repel each other, the magnetic rack 406 will reciprocate under the repulsive force of the magnetic blocks 408 on both sides and the restoring force of the telescopic springs 407 on both sides. By continuously pushing the magnetic rack 406, the magnetic rack 406 can be continuously reciprocated, thereby driving the gear 409 to rotate. The gear 409 drives the cleaning brush 413 to rotate through the rotating shaft 410, thereby stirring the bubbles on the liquid surface, dispersing the bubbles, preventing the bubbles from staying on the surface of the sewage, and ensuring that the sewage and the subsequent treatment agents are evenly mixed.

[0031] Embodiment 2:

[0032] On the basis of Example 1, a block 203 is fixedly connected to the right side of the partition 2, and a filter screen 202 is connected to the top of the block 203. The filter screen 202 has two layers. The mesh diameter of the top filter screen 202 is larger than that of the bottom filter screen. The height of the bottom filter screen 202 is higher than the drain pipe 3. The three connecting grooves 201 and the two layers of filter screens 202 are distributed at intervals.

[0033] Working principle: When treating sewage, firstly, the sewage is introduced into the sewage treatment tank 1. When the sewage liquid level is slightly higher than the movable plate 405, the treatment agent is added. After the reaction is carried out, bubbles are generated. By starting the motor 401, the output shaft of the motor 401 drives the screw 402 to rotate, so that the screw nut 403 moves on the surface of the screw 402, and the screw nut 403 drives the movable plate 405 to move on the sewage liquid surface. The movable plate 405 drives the driving plate 411 to drive the bubbles. The bubbles are driven to the right side of the sewage treatment tank 1, and then the bubbles are driven to the right side of the sewage treatment tank 1. After the motor 401 is reversed, the movable plate 405 and the driving plate 411 move to the left. After several reciprocating movements, all the bubbles are pushed to the right side of the sewage treatment tank 1, and the electric control valve inside the connecting groove 201 is opened to allow the sewage with bubbles to flow out from the top connecting groove 201. After the sewage with bubbles flows out, it is filtered by the filter screens 202 on both sides, so that the bubbles are trapped, thereby achieving the effect of dispersing the bubbles. After the treatment agent reacts completely with the sewage, the electric control valve inside the bottom connecting groove 202 is opened to allow the sewage to flow out and finally be discharged from the sewage treatment tank 1 from the drain pipe 3.
