Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically referring to an interception device for wastewater treatment in a wastewater treatment pond. Background Technology

[0002] Wastewater treatment ponds typically require interception during wastewater treatment, primarily to intercept floating debris such as leaves, branches, plastic film, paper, and fibers. If these floating objects are not intercepted, they may flow into subsequent treatment units with the water flow, clogging pipes, affecting the normal operation of equipment, and potentially having an adverse impact on the treatment effect.

[0003] A search revealed CN221846328U, which discloses an interception device for sewage treatment in a sewage treatment pond. This device employs a cleaning mechanism to collect and remove debris accumulated at the inlet side of the interception screen, preventing blockage and thus reducing the screen's sewage treatment efficiency. While it can clean the screen to some extent, it has some shortcomings in practical use: 1. The cleaning plate is raised and lowered by a cylinder, limiting the cleaning height and preventing complete vertical cleaning of the screen; 2. Although the collected debris can be collected, it is not convenient to release it promptly. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, after intercepting debris in a sewage tank using a bar screen, it is inconvenient to clean the intercepted debris, and at the same time, the debris attached to the bar screen cannot be completely cleaned from top to bottom.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A sewage treatment interception device for sewage treatment includes a sewage tank, in which a grid is inserted. A horizontal plate spans the upper end of the sewage tank and is located on one side of the grid. A lifting device is provided in the horizontal plate. A lifting plate is connected to the lower end of the lifting device. An elastic connecting device is provided in the lifting plate. A collection trough is provided on the side of the elastic connecting device near the grid. The length of the collection trough is equal to the width of the grid, and the bottom of the collection trough is a perforated mesh.

[0006] Furthermore, the lifting device includes a screw drum, which rotates in the horizontal plate via bearings. A second gear is fixedly connected to the upper end of the screw drum. A lead screw is threadedly connected to the screw drum, and the lower end of the lead screw is fixedly connected to the lifting plate. A motor is fixedly connected to the horizontal plate. The output end of the motor is connected to a first gear and meshes with the second gear. A guide post is fixedly connected to both sides of the lead screw on the upper end of the lifting plate and extends upward through the horizontal plate.

[0007] Furthermore, the elastic connection device includes a second guide post, which passes through the lifting plate and is fixedly connected to the side wall of the collection trough. Several groups of the second guide posts are evenly distributed along the length of the lifting plate, and a spring is sleeved on each group of the second guide posts. One end of the spring is fixedly connected to the lifting plate and the other end is fixedly connected to the side wall of the collection trough. The spring maintains the elastic force on the collection trough so that the collection trough fits against the grid mesh.

[0008] Furthermore, the upper side wall of the sewage tank is provided with a discharge port aligned with the side wall of the collection tank, and both ends of the collection tank are provided with doors that can be opened and closed.

[0009] Furthermore, the bottom wall and side walls of the sewage tank are provided with limiting plates, and the grid mesh is located in the limiting plates.

[0010] The beneficial effects achieved by adopting the above-described structure are as follows:

[0011] 1. This utility model, by setting up a lifting device, uses a motor to drive gear one to rotate, and meshes with gear two to rotate. Gear two drives the screw drum to rotate in the horizontal plate, and the screw is driven to rise and fall. The screw pulls the lifting plate to rise and fall. Through the collection trough, the debris attached to one side of the grid can be scraped and cleaned. The rising and falling of the screw can drive the collection trough to move up and down in a full range, so as to thoroughly clean the grid.

[0012] 2. This utility model, by setting an elastic connecting device, allows the collection trough to fit tightly against the grid under the action of the spring, which can more thoroughly clean the debris on the grid. At the same time, the two ends of the collection trough are equipped with doors that can be opened and closed. When the collection trough is raised and lowered to the discharge port, the workers can use the external scraper to scrape the debris in the collection trough and clean it out from the discharge port, thus achieving the purpose of timely cleaning of the collection trough.

Detailed Implementation

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] like Figure 1-4 This utility model discloses a sewage treatment interception device for sewage treatment ponds, including a sewage pond 1, a bar screen 2 inserted into the sewage pond 1, and limit plates 17 provided on the bottom and side walls of the sewage pond 1. The bar screen 2 is located in the limit plates 17 to ensure the stability of the bar screen 2. A horizontal plate 3 spans across the upper end of the sewage pond 1 and is located on one side of the bar screen 2. A lifting device 4 is provided in the horizontal plate 3, and a lifting plate 5 is connected to the lower end of the lifting device 4. An elastic connecting device 6 is provided in the lifting plate 5. A collection trough 7 is provided on the side of the elastic connecting device 6 near the bar screen 2. The length of the collection trough 7 is equal to the width of the bar screen 2, and the bottom of the collection trough 7 is shaped like a perforated mesh. A discharge port 16 is provided in the upper side wall of the sewage pond 1 and is aligned with the side wall of the collection trough 7. Both ends of the side wall of the collection trough 7 are provided with doors that can be opened and closed. By opening the doors, the staff can stand on the horizontal plate 3 and scrape the debris in the collection trough 7 out of the discharge port 16 with the help of a scraper.

[0021] like Figure 1-3The lifting device 4 includes a wire drum 8, which rotates in the horizontal plate 3 via bearings. A gear 9 is fixedly connected to the upper end of the wire drum 8, and a lead screw 10 is threadedly connected to the wire drum 8. The lower end of the lead screw 10 is fixedly connected to the lifting plate 5. A motor 11 is fixedly connected to the horizontal plate 3. The output end of the motor 11 is connected to a gear 12 and meshes with the gear 9. Guide posts 13 are fixedly connected to both sides of the lead screw 10 on the upper end of the lifting plate 5 and extend upward through the horizontal plate 3. The rotation of the wire drum 8 is achieved by the gear 12 meshing with the gear 9. The wire drum 8 drives the lead screw 10 to rise and fall, so that the debris on one side of the grid mesh 2 can be scraped and collected through the collection trough 7, and the grid mesh can be thoroughly cleaned from top to bottom.

[0022] like Figure 2 and 4 The elastic connection device 6 includes a second guide post 14, which passes through the lifting plate 5 and is fixedly connected to the side wall of the collection tank 7. Several groups of second guide posts 14 are evenly distributed along the length of the lifting plate 5. Each group of second guide posts 14 is fitted with a spring 15. One end of the spring 15 is fixed to the lifting plate 5 and the other end is fixed to the side wall of the collection tank 7. The spring 15 maintains the elastic force on the collection tank 7 so that the collection tank 7 fits against the grid mesh 2. In this way, during the lifting and lowering process of the collection tank 7, the debris on the grid mesh 2 can be scraped more thoroughly.

[0023] In practical use, when the sewage in the sewage tank 1 flows through the bar screen 2, the bar screen 2 will intercept the debris. The debris will be concentrated on one side of the bar screen 2. When it is necessary to clean the debris on one side of the bar screen 2, the motor 11 is started, the gear 12 meshes with the gear 29 and rotates, the gear 29 drives the screw drum 8 to rotate. Since the screw 10 does not rotate, the screw 10 will drive the lifting plate 5 to rise and fall. The guide column 13 can ensure that the lifting plate 5 rises and falls smoothly.

[0024] Because one side of the lifting plate 5 is fixed to the side wall of the collection tank 7 by the guide post 2 14 and the spring 15 maintains the elastic force on the collection tank 7, the collection tank 7 is tightly attached to the grid 2 when it is raised and lowered, which can more thoroughly clean the debris attached to the grid 2. The bottom of the collection tank 7 is a mesh screen device, which realizes the collection of debris and filters the sewage. When the collection tank 7 rises to the level of the discharge port 16, by opening the doors at both ends of the collection tank 7, the staff can stand on the horizontal plate 3 and use the scraper in the prior art to push the debris in the collection tank 7 out from the discharge port 16, so as to achieve timely cleaning of the collection tank 7.

[0025] It should be noted that the motor 11 in this solution is powered by an external wiring and controlled by a switch, which can realize the forward and reverse switching of the motor 11. The doors on both sides of the collection trough 7 can be opened by hinges as we commonly know, and closed by pins. This is very easy to achieve in practical applications, and will not be described again.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
