Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology for pumping stations, specifically to a slag removal device and an integrated pumping station. Background Art

[0002] A pumping station is a type of lifting equipment used to lift sewage or rainwater. It is typically manufactured and assembled in a factory and then transported to the site for rapid installation, offering advantages such as high reliability, short installation time, and relatively low cost. Within existing pumping stations, common methods for removing debris from the water include using basket screens or pulverizing screens. Basket screens trap debris that remains in the water for extended periods, which can be washed into the pump sump during operation, affecting pump performance. Furthermore, a large amount of debris can reduce water flow capacity, leading to a significant difference in water level before and after the screen in high-flow conditions, creating a safety hazard. Pulverizing screens, on the other hand, can only break up larger, harder debris in the water. They are ineffective at intercepting and cutting soft, long, and thin debris, often causing inlet blockage, affecting water flow, and ultimately clogging the downstream sewage pumps.

[0003] To address the aforementioned issues, Chinese utility model patent CN216340023U discloses a "Garbage Retrieval Device for Pumping Stations," which uses two sets of mesh filter boxes installed on a U-shaped chute to filter waste discharged from the pumping station. However, in this technology, the connection between the two sets of mesh filter boxes and the pumping station inlet always has a specific order. This means that when one mesh filter box is full and removed, the next mesh filter box cannot connect without any time difference. This results in water entering the pumping station still containing unfiltered garbage, and over time, the accumulated garbage will affect the normal operation of the water pump.

[0004] In view of this, the present invention provides a slag removal device and an integrated pumping station. The slag removal device is integrated and installed inside the integrated pumping station, which can continuously intercept, remove and transfer the garbage entering the pumping station. This solves the technical problem in the prior art that the garbage entering the pumping station cannot be continuously removed, resulting in the garbage accumulating and being transferred to the back end, thereby affecting the normal operation of the water pump.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] In order to completely eliminate garbage in the water entering the pumping station and solve the problem of garbage accumulation affecting the normal operation of the pump, this utility model provides a slag removal device and an integrated pumping station, which can continuously filter the water entering the pumping station and remove garbage to achieve the purpose of thoroughly removing garbage.

[0026] It should be noted that the slag removal device described in this utility model is used in, but not limited to, pump stations. For ease of explanation, this utility model only uses the application of the slag removal device in a pump station as an example. The principle of the slag removal device applied to other types of equipment is essentially the same as that applied to a pump station, and will not be described in detail here.

[0027] Please see Figure 1As shown, in a first aspect, this embodiment relates to a slag removal device 100, installed inside a pump station 200. The slag removal device 100 includes a filter assembly 110 and a slag removal assembly 120. The filter assembly 110 is disposed at the water inlet 201 of the pump station 200. The slag removal assembly 120 is disposed on the water inlet side of the filter assembly 110. The slag removal assembly 120 includes a drive unit 121, a rotating unit 122, and a slag removal unit 123. The drive unit 121 is pulverically connected to the rotating unit 122. A plurality of slag removal units 123 are spaced apart on the rotating unit 122. The slag removal units 123 rotate synchronously with the rotating unit 122 to remove the garbage filtered by the filter assembly 110.

[0028] In this embodiment, the filter assembly 110 is located at the inlet 201 of the pump station 200, and the sludge removal assembly 120 is located on the water inlet side of the filter assembly 110. The sludge removal assembly 120 includes a drive unit 121, a rotating unit 122, and a scooping unit 123. Thus, by installing the sludge removal device 100 inside the pump station 200, the water entering from the inlet 201 of the pump station 200 first passes through the filter assembly 110, intercepting the garbage in the water. The intercepted garbage can be scooped up and carried away by the rotating scooping unit 123, realizing continuous filtration of the water entering the pump station 200 and completely eliminating the garbage in the water. Therefore, it can avoid the impact of garbage accumulation on the normal operation of the water pump.

[0029] In one embodiment, the filter assembly 110 includes a first grille 111 and a second grille 112. The first grille 111 is disposed at the lower edge of the inlet 201 and arranged along the horizontal direction of the pump station 200. The second grille 112 is disposed in front of the inlet 201 and arranged along the vertical direction of the pump station 200. The bottom of the second grille 112 is connected to one end of the first grille 111. The slag removal assembly 120 is disposed on the upper part of the first grille 111 and located on the side of the second grille 112 near the inlet 201.

[0030] In one embodiment, the first grille 111 is an upward-opening arc-shaped grille, and the second grille 112 is a planar grille.

[0031] In one embodiment, the drive unit 121 is a drive motor, the rotating unit 122 is a rotating chain, the rotating chain is connected to the drive motor, the rotating chain is arranged along the vertical direction of the pump station 200, and the top of the rotating chain is bent downward to form the feeding end of the slag removal assembly 120; the scooping unit 123 is a slag removal tooth, one end of which is fixedly installed on the side of the rotating chain, and the other end is used to scoop up garbage.

[0032] In one embodiment, the slag removal device 100 further includes a collection component 130, which is disposed at the discharge end of the slag removal component 120.

[0033] In one embodiment, the collection assembly 130 includes a collection hopper 131 and a waste bin 132. The inlet end of the collection hopper 131 is connected to the discharge end of the slag removal assembly 120. The waste bin 132 is disposed below the collection hopper 131 and placed on the maintenance platform 220 of the pump station 200.

[0034] Secondly, this embodiment provides an integrated pumping station 200, including a pumping station housing 210 and a slag removal device 100 provided in the first aspect, wherein the slag removal device 100 is disposed inside the housing 210.

[0035] In one embodiment, the housing 210 is a cylindrical structure formed by stainless steel sheets with a wavy shape on both sides. The use of stainless steel extends its service life. The wavy design of the housing 210 reduces the wall thickness of the stainless steel sheets, effectively enhancing its circumferential rigidity while reducing the need for internal supports and reinforcing materials, thus reducing deformation caused by underground soil during buried installation. In contrast, existing pump station housings 210 are commonly made of reinforced concrete or fiberglass. Fiberglass housings cause significant environmental pollution during production, while reinforced concrete housings are too heavy for easy transportation.

[0036] It is understood that when the slag removal device 100 is installed inside the shell 210 of the pump station 200, the installation requirements can be met by using some structural steel. This is a common technical means in the field and will not be elaborated here.

[0037] In addition, a cover plate 230 is provided on the top of the housing 210 to facilitate the hoisting of the equipment and the passage of personnel, and to facilitate maintenance personnel to enter the pump station 200 for operation and maintenance; a rainproof and insect-proof breathable cap 240 is also provided on the top of the housing 210 to keep the air circulating inside the pump station 200.

[0038] To better understand this utility model, the following is combined with... Figure 1 The working process of the technical solution in this embodiment will be described in detail below:

[0039] 1. Water from inlet 201 passes through the first screen 111 and the second screen 112. Debris in the water is trapped inside the screens, and the water flows into the pump pit.

[0040] 2. Driven by the rotating part 122, the retrieval unit 123 continuously retrieves the garbage from the gaps between the first screen 111 and the second screen 112, grabs the garbage attached to it, and lifts it out of the water.

[0041] 3. The salvage unit 123 pulls the garbage into the collection bin 131, where it is stored in the garbage bin 132 on the maintenance platform 220;

[0042] 4. After a period of garbage collection and water filtration, the garbage bin 132 is removed manually through the cover plate 230 (using existing lifting devices) and transferred to the ground.

[0043] 5. The water inside the pump pit is lifted to a designated height by the sewage lift pump and then flows downstream through the outlet 202 of the pump station 200.

[0044] 6. The top cover plate 230 facilitates the hoisting of equipment and the passage of personnel, and makes it convenient for maintenance personnel to enter the pump station for operation and maintenance;

[0045] 7. A strong exhaust device is installed under the rainproof, insect-proof, and breathable cap 240 to keep the air circulating inside the pump station 200.

[0046] In summary, the slag removal device and integrated pump station provided by this utility model can intercept, collect, and transfer garbage in the water to the surface, preventing garbage from entangled in the water pump and causing blockages, resulting in shutdowns or damage. Furthermore, designing the shell 210 of the pump station 200 as a stainless steel corrugated pipe structure reduces material consumption while ensuring the strength and rigidity of the cylinder. The stainless steel material thickness can be controlled between 2 and 5 mm, effectively controlling its weight and cost.

[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
