Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a foam elimination device for wastewater treatment. Background Technique

[0002] In the field of wastewater treatment, the generation of foam is a common and troublesome problem. Organic substances, surfactants, and gases generated by microbial metabolism in wastewater are prone to form a large amount of foam during treatment processes such as stirring and aeration. These foams not only affect the efficiency of wastewater treatment but may also overflow from the treatment device, causing secondary pollution to the environment. At this time, a foam elimination device is needed to eliminate them.

[0003] In the prior art, most foam elimination methods include adding defoamers, mechanical crushing, etc. However, these methods have many deficiencies. Although the addition of defoamers can quickly eliminate foam, it may introduce new chemical substances, affecting the effluent quality of wastewater treatment and requiring additional costs. The mechanical crushing method has problems such as complex equipment, high energy consumption, and difficult maintenance. Therefore, there is an urgent need in the market for a foam elimination device with a simple structure, convenient operation, and no chemical pollution. Content of the Utility Model

[0004] The purpose of the utility model is to provide a foam elimination device for wastewater treatment to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A foam elimination device for wastewater treatment includes a treatment tank. A lifting plate is slidably arranged on the right side wall of the treatment tank. A cleaning plate is arranged at the bottom of the lifting plate. A vibration motor is arranged at the top of the lifting plate. An installation plate is also arranged on the side wall of the treatment tank. A threaded rod is rotatably arranged on the front installation plate. A sliding rod is arranged on the rear installation plate. A cleaning plate is also arranged on the sliding rod. The threaded rod penetrates through the cleaning plate and is threadedly connected with the cleaning plate. A screw rod is rotatably arranged inside the right side wall of the treatment tank.

[0021] Embodiment

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a foam elimination device for wastewater treatment includes a treatment tank 1. A lifting plate 7 is slidably arranged on the right side wall of the treatment tank 1. A cleaning plate 8 is arranged at the bottom of the lifting plate 7, and a vibration motor 9 is arranged at the top of the lifting plate 7. When it is necessary to eliminate the foam in the wastewater, the cleaning plate 8 is lowered by using the lifting plate 7 so that it is located above the wastewater surface. Then, the vibration motor 9 is started to drive the cleaning plate 8 to vibrate, thereby performing the foam elimination work. A limiting plate 101 is also arranged on the rear side wall of the treatment tank 1. A sliding groove is arranged on the limiting plate 101. A slider 701 is arranged on the outer wall of the rear side of the lifting plate 7, and the slider 701 is slidably connected with the sliding groove. At this time, under the action of the sliding groove and the slider 701, the lifting efficiency of the lifting plate 7 is ensured, and further the use efficiency of the cleaning plate 8 is ensured.

[0023] An installation plate 2 is also arranged on the side wall of the treatment tank 1. A threaded rod 4 is rotatably arranged on the front installation plate 2. A sliding rod 3 is arranged on the rear installation plate 2. A cleaning plate 5 is also arranged on the sliding rod 3. The threaded rod 4 penetrates through the cleaning plate 5 and is threadedly connected with the cleaning plate 5. At this time, rotating the threaded rod 4 can drive the cleaning plate 5 to move left and right on the treatment tank 1, thereby scraping off the impurities after the foam is removed, and further reducing the occurrence of impurities remaining in the water. To a certain extent, the quality of the device for cleaning wastewater foam is ensured. A motor 6 is also arranged on the outer wall of the front installation plate 2. The power output shaft of the motor 6 is connected with the threaded rod 4 through a coupling. At this time, the motor 6 can be used to drive the threaded rod 4 to rotate, and further scrape off the impurities on the water surface through the cleaning plate 5, ensuring the quality of the device for wastewater treatment.

[0024] A screw rod 10 is also rotatably arranged inside the right side wall of the treatment tank 1. The screw rod 10 penetrates through the lifting plate 7 and is threadedly connected with the lifting plate 7. At this time, rotating the screw rod 10 can drive the lifting plate 7 to move up and down, and further adjust the position of the cleaning plate 8 so that the cleaning plate 8 can better perform the foam elimination work.

[0025] A worm gear 11 is also arranged on the screw rod 10 through a key connection. A worm 12 is also rotatably arranged on the right side wall of the treatment box 1. The worm 12 meshes with the worm gear 11. At this time, rotating the worm 12 can drive the screw rod 10 to rotate through the worm gear 11, thereby adjusting the position of the cleaning plate 8. In addition, due to the self-locking function of the worm gear 11 and the worm 12, the adjusted position of the cleaning plate 8 can be fixed, thereby ensuring the use efficiency of the cleaning plate 8. A servo motor 13 is also arranged on the right side wall of the treatment box 1. The power output shaft of the servo motor 13 is connected to the worm 12 through a coupling. At this time, the servo motor 13 can drive the worm 12 to rotate, thereby better adjusting the position of the cleaning plate 8.

[0026] A drain pipe 14 is also arranged on the right side wall of the treatment box 1. A valve 15 is arranged on the drain pipe 14. Under the action of the drain pipe 14, the treated waste water can be discharged. In addition, under the action of the valve 15, the drain pipe 14 can be controlled, thereby facilitating the better discharge of the waste water.

[0027] During actual use, the staff introduces the waste water to be treated into the treatment box 1 through a conduit. Then, the servo motor 13 is started to drive the screw rod 10 to rotate by using the worm 12 and the worm gear 11, thereby driving the lifting plate 7 to slide up and down along the right side wall of the treatment box 1, so that the cleaning plate 8 can accurately align with the foam layer on the water surface of the waste water. When the cleaning plate 8 is adjusted to the appropriate position, that is, not far above the water surface of the waste water, the vibration motor 9 is started. The vibration generated by the vibration motor 9 is transmitted to the cleaning plate 8 through the lifting plate 7, so that the cleaning plate 8 vibrates at a high frequency above the water surface, dispersing and destroying the foam in the waste water and causing it to quickly dissipate. Then, the motor 6 is started, so that the threaded rod 4 drives the cleaning plate 5 to slide left and right along the sliding rod 3. The moving path of the cleaning plate 5 covers the water surface area of the treatment box 1, scraping the remaining impurities off the water surface and taking them away from the area as the cleaning plate 5 moves, effectively reducing the possibility of the impurities re-entering the water. During the treatment process, the foam and impurities in the waste water are gradually eliminated and cleaned until the treatment requirements are met. At this time, the valve 15 can be opened, and the treated waste water can be discharged from the treatment box 1 through the drain pipe 14 for the next treatment or discharge.
