Abstract
Description
Technical Field
[0001] This application relates to the field of water body cleaning technology, specifically to a reverse-retrieval type bar screen cleaning rake. Background Technology
[0002] When cleaning water bodies, wastewater needs to be separated from the water using a bar screen before entering the wastewater treatment plant. Currently, the reverse-slaughter bar screen is widely used due to its good separation effect and low cost. The principle of the reverse-slaughter bar screen is mainly that its several cleaning rakes move in a cycle to pick up the waste. When the rakes rise to their highest point, they turn downwards, and the waste caught on the rakes falls into a pre-placed collection box under gravity for unified treatment. However, in actual wastewater treatment processes, it has been found that wastewater contains a large amount of solid grease, which has a smooth surface and is not easily fixed, often entering subsequent pipelines with the wastewater and causing pipeline blockages. Utility Model Content
[0003] This application provides a reverse-retrieval bar screen cleaning rake, which solves the problem that the existing reverse-retrieval bar screen cleaning rake has low retrieval efficiency and difficulty in cleaning solid grease.
[0004] The technical solution of this application is as follows:
[0005] A reverse-retrieval type bar screen with cleaning rakes includes a frame placed in a body of water. The front side of the frame has a smooth, inclined climbing surface, and traction tracks are provided on both sides of the climbing surface, rotating in a circular motion from the bottom to the top.
[0006] A first rake and a second rake are connected between the two traction tracks.
[0007] The first rake includes a cylindrical roller and the cylindrical roller extends toward and away from the climbing surface with first toothed spikes, and a first gap is formed between the first toothed spikes in the same direction;
[0008] The second toothed rake includes two rectangular toothed plates, one of which extends in a direction perpendicular to the climbing surface, and the other toothed plate intersects the first toothed plate at an angle and has several through holes at the junction of the two toothed plates. The toothed plate extends with a second toothed spike, and the second toothed spike is aligned with the first gap along the climbing surface.
[0009] Furthermore, the bottom of the climbing surface is provided with a grid.
[0010] Furthermore, the angle formed by the two toothed plates facing upward toward the climbing surface is 120°.
[0011] Furthermore, a second gap is formed between the second toothed pins, and the through hole is aligned with the second gap.
[0012] Furthermore, a motor for driving the traction track is provided above the frame.
[0013] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows:
[0014] 1. This application uses both cylindrical rollers and toothed nail plates. The cylindrical rollers are less likely to trap garbage, which can ensure the operating efficiency of the bar screen. The two toothed nail plates at a certain angle can scoop up blocky pollutants in the water, such as grease. The two work together to ensure scooping efficiency and increase the variety of pollutants scooped up.
[0015] 2. In this application, the two toothed nail plates are provided with through holes at the joint. The through holes can drain the water accumulated on the toothed nail plates and prevent the intercepted blocky objects from leaving the toothed nail plates with the water flow.
[0016] 3. In this application, the second toothed nail is aligned with the first gap formed by the first toothed nail, and the two sets of toothed nails can compensate for pollutants that may be neglected to be retrieved at different positions, thereby improving the retrieval effect.
[0017] 4. In this application, the toothed plate of the second rake and the second toothed nail can form a good "net" that can catch blocky pollutants or pollutants that fall from the toothed nail. When the first rake and the second rake are set at intervals, a continuous "net" can be formed, thereby improving the success rate of retrieval. Attached Figure Description

[0024] Based on the background technology described, as shown in the appendix Figure 1 ~Appendix Figure 3 As shown, this application provides a reverse-dredging bar screen 6 machine, including a frame 1 placed in a body of water, the front side of the frame 1 having a smooth climbing surface 2 and the climbing surface 2 being inclined, and the climbing surface 2 having traction tracks on both sides that rotate from its bottom to its top. A first toothed rake 4 and a second toothed rake 5 are connected between the two traction tracks; the first toothed rake 4 includes a cylindrical roller 4-1 and the cylindrical roller 4-1 extends with first toothed spikes 4-2 towards and away from the climbing surface 2, and a first gap 4-3 is formed between the first toothed spikes 4-2 in the same direction; the second toothed rake 5 includes two rectangular toothed spike plates 5-1, one of which extends in a direction perpendicular to the climbing surface 2, and the other toothed spike plate 5-1 intersects with the first toothed spike plate 5-1 at an angle and has a plurality of through holes 5-3 at the junction of the two toothed spike plates 5-1, and the toothed spike plate 5-1 extends with second toothed spikes 5-2, and the second toothed spikes 5-2 are aligned with the first gap 4-3 along the direction of the climbing surface 2.
[0025] The frame 1 is submerged in water, with its upper part exposed. The traction track rotates upwards from underwater, driving the first rake 4 and the second rake 5 in a cyclical motion. The first spikes 4-2 and 5-2 on the first rake 4 and the second rake 5 are used to retrieve debris from the water. The first rake 4 uses a cylindrical roller 4-1, which is fixed to one segment of the traction track and does not rotate around its own axis. The first spikes 4-2 are installed on it by welding or sleeve, and the first spikes 4-2 are spaced apart to form a first gap 4-3. The second rake 5 uses rectangular spike plates 5-1. One spike plate 5-1 is perpendicular to the climbing surface 2 and points downwards, providing a larger retrieval area. The other spike plate 5-1 forms an angle with the first spike plate 5-1, creating a structure that can support blocky objects, thus expanding the rake's function. That is, the second rake 5 no longer cleans up garbage by simply using spikes to hook pollutants; it can also drag pollutants out of the water by holding them in place, which helps to achieve thorough retrieval. It should be noted that in this application, the second spikes 5-2 are arranged between the first gaps 4-3, allowing for comprehensive hooking and further improving the retrieval effect. The second rake 5 can be made by bending and casting a single steel plate, and then cutting out the second spikes 5-2. This method is easier to process and has better overall integrity compared to using cylindrical rollers 4-1 and first spikes 4-2. This application uses both cylindrical rollers 4-1 and spike plates 5-1. The cylindrical rollers 4-1 are less prone to snagging garbage, ensuring the operating efficiency of the bar screen 6, while the two spike plates 5-1 at a certain angle can retrieve blocky pollutants in the water, such as grease. The two work together functionally to ensure retrieval efficiency and increase the variety of pollutants retrieved.
[0026] In a preferred embodiment of this application, the bottom of the climbing surface 2 is provided with a grille 6. The grille 6 can act as a filter to prevent garbage from entering the subsequent sewage treatment tank.
[0027] In a preferred embodiment of this application, the included angle between the two toothed plates 5-1 facing upward toward the climbing surface 2 is 120°.
[0028] In a preferred embodiment of the above implementation, a second gap 5-4 is formed between the second toothed nails 5-2, and the through hole 5-3 is aligned with the second gap 5-4. In this application, the toothed nail plates 5-1 and the second toothed nails 5-2 of the second toothed rake 5 can form a good "net," capable of catching blocky pollutants or pollutants that have fallen from the toothed nails. When the first toothed rake 4 and the second toothed rake 5 are spaced apart, a continuous "net" can be formed, thereby improving the success rate of retrieval. The two toothed nail plates 5-1 are provided with through holes 5-3 at their junction. The through holes 5-3 can drain water accumulated on the toothed nail plates 5-1, preventing intercepted blocky objects from detaching from the toothed nail plates 5-1 with the water flow.
[0029] In a preferred embodiment of this application, a motor 7 for driving the traction track is provided above the frame 1. The motor 7 drives the traction track to rotate, thereby realizing the rotation of the first rake 4 and the second rake 5.
[0030] For any parts not mentioned in this application, existing technologies may be used or referenced.
[0031] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
