Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically relating to a sewage treatment bar discharge device. Background Technology

[0002] In order to intercept larger particles of garbage and long fibers in the sewage during the process of sewage collection and transportation to sewage treatment plants through pipelines or pipe networks, and to prevent the water pumps that lift sewage from becoming blocked and affecting sewage transportation, sewage screen wells must be built in actual operation.

[0003] However, traditional street grilles, typically composed of a set of parallel bars, are simply metal mesh structures. Given the complex environment of road surfaces and the variety of pollutants encountered, these grilles can become clogged if not cleaned regularly. While the mesh can isolate large particles of pollutants and prevent them from entering drainage pipes, it also affects the grille's permeability. Without timely cleaning, it's difficult to maintain sufficient permeability, leading to water accumulation and difficulty in draining pollutants. Furthermore, the mesh structure makes cleaning difficult, requiring workers to clean each individual gap, which is tedious. To address these issues, a sewage treatment grille discharge device is proposed. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a sewage treatment bar discharge device; through structural optimization, it makes it easier for workers to clean the bar.

[0005] This utility model provides a sewage treatment bar discharge device, including a base frame, on which connecting grooves are symmetrically provided. A movable frame is hinged between the base frame and the connecting grooves. Several crossbeams are uniformly fixedly connected to the movable frame, and several slots are uniformly provided between the crossbeams. A groove is provided on the movable frame, and a movable frame is provided on the groove. A longitudinal beam is fixedly connected to the movable frame corresponding to the slot. The longitudinal beam and the slot are mutually engaged, and the movable frame and the groove are mutually engaged.

[0006] Furthermore, the bottom frame is provided with a second groove, and the movable frame is provided with a pull ring corresponding to the second groove.

[0007] Furthermore, the movable frame two is symmetrically provided with pull ring two.

[0008] Furthermore, the first movable frame and the second movable frame are made of fiberglass.

[0009] Furthermore, the crossbeams and longitudinal beams are made of fiberglass.

[0010] Furthermore, the depth of the slot is greater than the depth of the groove.

[0011] The beneficial effects of this utility model are:

[0012] This utility model improves and optimizes the structure by decomposing the traditional fixed mesh grille into parallel sections, making it easier for workers to clean. They can directly clean the parallel sections, greatly improving cleaning efficiency and reducing the difficulty of cleaning for workers. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please refer to the accompanying diagrams for all instruction manuals:

[0022] A sewage treatment bar discharge device includes a bottom frame 1, with symmetrical connecting grooves 2 on the bottom frame 1. A movable frame 3 is hinged between the bottom frame 1 and the connecting grooves 2. A plurality of crossbeams 4 are uniformly fixedly connected to the movable frame 3. A plurality of slots 5 are uniformly provided between the crossbeams 4. A groove 6 is provided on the movable frame 3. A movable frame 7 is provided on the groove 6. A longitudinal beam 8 is fixedly connected to the movable frame 7 corresponding to the slots 5. The longitudinal beam 8 and the slots 5 fit together. The movable frame 7 and the groove 6 fit together.

[0023] As can be seen from the above description, the bottom frame 1 is pre-installed on the ground. The movable frame 1 3 and the crossbeam 4 are hinged to the bottom frame 1 and can flip each other. The movable frame 2 7 and the longitudinal beam 8 are plugged into the movable frame 1 3 and the crossbeam 4. The movable frame 1 3 and the movable frame 2 7 can be separated by simply lifting the movable frame 2 7.

[0024] As a technical optimization of this utility model, the bottom frame 1 is provided with a groove 2 9, and the movable frame 3 is provided with a pull ring 10 corresponding to the groove 2 9;

[0025] As can be seen from the above description, the groove 29 provides sufficient space for the use of the pull ring 10, and the worker uses a tool to pull the movable frame 3 through the pull ring 10.

[0026] As a technical optimization of this utility model, pull rings 11 are symmetrically provided on the movable frame 7;

[0027] As can be seen from the above description, the pull ring 211 allows workers to easily lift out the movable frame 27 using tools.

[0028] As a technical optimization of this utility model, movable frame 3 and movable frame 7 are made of fiberglass; crossbeam 4 and longitudinal beam 8 are made of fiberglass.

[0029] As described above, fiberglass (glass fiber reinforced plastic) combines the high strength of glass fiber with the corrosion resistance of plastic. It boasts advantages such as light weight, high strength, corrosion resistance, and aging resistance. Its strength is comparable to steel, and it can be used for extended periods in harsh wastewater environments. Furthermore, fiberglass gratings have a smooth surface, are less prone to scaling, and have low head loss, facilitating the smooth flow of wastewater.

[0030] As a technical optimization of this utility model, the depth of the slot 5 is greater than the depth of the groove 6;

[0031] As can be seen from the above description, this depth makes the connection between the crossbeam 4 and the longitudinal beam 8 more stable and secure.

[0032] The working process of this utility model is as follows:

[0033] During cleaning, the movable frame 2 7 is pulled out by the pull ring 2 11 and separated from the movable frame 1 3 to clean the gaps between the longitudinal beams 8 on the movable frame 2 7; in addition, the movable frame 1 3 is flipped up to clean the gaps between the cross beams 4. Since there is no mutual restraint between the cross beams 4 and the longitudinal beams 8, the overall cleaning efficiency can be effectively improved.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
