Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a foam removal structure for wastewater treatment ponds. Background Technology

[0002] During wastewater treatment, large amounts of scum are easily generated in structures such as biological reactors and sedimentation tanks. This scum mainly originates from surfactants, greases, and microbial metabolites in the wastewater. Under aeration and stirring, it forms a stable gas-liquid mixture. If not cleaned in time, it can cause multiple problems: First, scum accumulation hinders the contact between wastewater and air, reducing biological treatment efficiency and affecting effluent quality; second, excessive scum overflowing from the tank can pollute surrounding equipment and the environment, increasing subsequent cleaning costs; third, long-term stagnation of scum easily breeds anaerobic bacteria, producing foul-smelling gases that endanger the health of operators.

[0003] The current mainstream methods for cleaning scum have obvious drawbacks: First, manual cleaning relies on manual retrieval, which is inefficient, labor-intensive, and difficult to operate continuously. It is suitable for small treatment tanks but cannot meet the needs of large-scale sewage treatment. Second, mechanical scraping devices mostly use fixed scraper structures, which can only clean local areas on the surface of the tank. Moreover, the scraper is prone to friction with the tank body, leading to equipment wear and secondary pollution of sewage. Furthermore, its scraper is not suitable for different types and shapes of sewage tanks.

[0004] In summary, existing foam cleaning technologies are insufficient in terms of cleaning efficiency, thoroughness, energy consumption, and environmental friendliness to meet the demands of modern wastewater treatment for high efficiency, stability, and low consumption. There is an urgent need to develop a foam cleaning structure for wastewater treatment ponds that is simple in structure, thorough in cleaning, low in operating cost, and free from secondary pollution. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0024] Please see Figures 1 to 4 Based on the application of a rectangular opening sewage tank for sewage treatment, a sewage treatment tank foam cleaning structure includes a collection box 1, a guide plate 2 is movably connected to the top side of the collection box 1 via a rotating shaft, and a water-blocking strip 3 is attached to the bottom of the guide plate 2 and bonded to the collection box 1.

[0025] The guide plate 2 has positioning rods 5 at both ends that are movably inserted into one end of the movable support arm 4, and the other end of the movable support arm 4 has a collection component 6. The collection component 6 has a drive component 7 on the side away from the collection box 1.

[0026] The collecting component 6 includes a main shaft 601 that is movably connected to the movable support arm 4. The main shaft 601 is fitted with a hollow bushing 602. Multiple collecting plates 603 are attached to the outside of the bushing 602. Multiple grooves that are adapted to the inner side of the collecting plates 603 are opened on the outside of the bushing 602.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the collecting plate 603 is composed of an insert plate and a collecting filter plate. The insert plate and the collecting filter plate are fixedly connected. Supporting corner plates are provided at equal intervals at the connection between the insert plate and the collecting filter plate. The edge of the collecting filter plate is serrated, and multiple water filtering holes are also provided at equal intervals on its surface. The outer end of the collecting filter plate is bent.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, the two ends of the drive assembly 7 are respectively installed in corresponding tracks, and the inside of the tracks is provided with racks that are adapted to the drive assembly 7.

[0029] In this embodiment, as Figure 4 As shown, the drive assembly 7 includes a drive shaft 701, with a geared motor at either end of the drive shaft 701, and drive gears 702 installed at both ends of the drive shaft 701.

[0030] In this embodiment, as Figure 4 As shown, a support shaft 703 is provided parallel to one side of the drive shaft 701. Both ends of the support shaft 703 are provided with transmission gears 704 that mesh with the drive gear 702. Belt drive components are provided on the inner side of both transmission gears 704.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the belt drive assembly consists of two drive pulleys and two transmission pulleys. Each drive pulley is connected to its corresponding transmission pulley via a V-shaped toothed belt. The two drive pulleys are respectively sleeved on both ends of the support shaft 703, and the two transmission pulleys are respectively sleeved on both ends of the collecting assembly 6.

[0032] In this embodiment, as Figure 1 and Figure 4 As shown, the main spindle 601, support shaft 703 and drive shaft 701 are parallel to each other, and positioning plates are sleeved at both ends of the three. The positioning plates are respectively provided with insertion holes that match the main spindle 601, support shaft 703 and drive shaft 701.

[0033] The foam removal structure of this wastewater treatment tank operates as follows:

[0034] First, parallel running tracks are erected on both sides of the sewage tank, and racks that are compatible with the drive gear 702 are fixedly installed in the tracks. Then, a reduction motor is installed at either end of the drive shaft 701.

[0035] The drive shaft 701 and the drive gears 702 at both ends are driven to rotate by the geared motor. The drive gears 702 move the entire device by cooperating with the rack. While the drive gears 702 are rotating, the transmission gears 704 are also rotated. The rotational power is transmitted to the main shaft 601 by the belt drive assembly. At this time, the rotation direction of the main shaft 601 is opposite to that of the drive shaft 701.

[0036] The main shaft 601, through the collection plate 603 mounted on its surface, lifts the foam on the surface of the sewage while the equipment is moving. The sewage and foam are temporarily separated by the filter opening on the surface of the collection plate 603. The continuously advancing collection plate 603 moves the foam to the guide plate 2 on the other side by rotating. The guide plate 2 is brush-shaped and scrapes the foam off the surface of the collection plate 603 and flows it into the collection box 1, thereby realizing the collection of foam on the surface of the sewage tank.

[0037] When used in wastewater treatment with a circular opening, a ring track is installed. The inner track is used for limiting and guiding, while a ring rack is arranged in the outer track. The drive shaft 701, near the center, does not require the installation of a drive gear 702, transmission gear 704, or corresponding belt drive assembly. A geared motor is installed at the other end of the drive shaft 701 as the power source. This allows the device to move along a circular path and clean the surface foam of the wastewater.
