Description

Technical Field

[0001] This application relates to the technical field of municipal road drainage equipment, specifically to a multi-stage filtration device for municipal road drainage. Background Technology

[0002] In municipal road drainage systems, ensuring smooth drainage and effective filtration of debris is crucial for the normal operation of a city. With the acceleration of urbanization, road drainage faces increasingly complex situations, placing ever higher demands on the performance of drainage filtration equipment.

[0003] Currently, existing drainage filtration equipment, such as the "Environmentally Friendly Filtration Device for Municipal Drainage" with patent number CN202421427858.1, has many problems that need to be solved. This device relies on a motor to drive brushes and agitator blades to clean and process debris, which makes the equipment structure complex, increasing manufacturing costs, maintenance difficulty, and the risk of failure. If the motor fails, the entire filtration device may not function properly.

[0004] Furthermore, the existing device can only clean debris above the filter guide plate, which has limitations. It cannot comprehensively, promptly, and effectively clean debris accumulated on the filter plate. When there is too much debris on the filter plate, it can easily cause blockage, severely affecting filtration efficiency and drainage smoothness, failing to meet the requirements of efficient and stable operation of municipal road drainage. These problems restrict the performance improvement of municipal road drainage systems, necessitating a more effective drainage filtration device to solve the problem. Summary of the Invention

[0005] In response to the aforementioned technical problems, this application addresses the issues of existing filtration equipment being prone to clogging, unable to continuously and efficiently filter without interrupting drainage, and inconvenient debris removal during municipal road drainage processes.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a multi-stage filtration device for municipal road drainage, comprising a housing, a connecting pipe and a support plate fixedly mounted on the housing, two conveyor chains slidably mounted on the support plate, the conveyor chains being located on two end faces of the support plate and slidably connected to the housing, multiple grooves being provided on the conveyor chains, and multiple sets of filter components being provided on the grooves, the filter components including one first filter plate, one second filter plate and one third filter plate, and a collection box slidably mounted on the housing, the collection box also being slidably connected to the support plate.

[0007] To better realize this application, the first filter plate, the second filter plate and the third filter plate each include a filter plate and a mounting rod, the mounting rod slides on the groove of the conveyor chain, and the filter plate has an arc-shaped structure and is elastic.

[0008] To better realize this application, the outer shell is further provided with two sets of protrusions, and each set of protrusions is provided with multiple protrusions.

[0009] To better realize this application, furthermore, multiple control rods are fixedly provided on the conveyor chain for controlling the movement of the conveyor chain on the support plate.

[0010] To better realize this application, a limit hook is further provided on the housing to limit the movement of the control lever.

[0011] To better realize this application, the collection box is further provided with a groove for workers to lift the collection box.

[0012] The technical solution provided in this application has the following advantages compared with the prior art:

[0013] 1. In this application, multiple filter components can be moved and switched via a conveyor chain. When a set of filter components accumulates a large amount of debris, it can be replaced in time, and filtration can continue without interrupting drainage, thus ensuring the smooth operation of the drainage system.

[0014] 2. The diameter of the filter holes in the first, second, and third filter plates decreases progressively, achieving graded filtration. This effectively intercepts debris of different sizes and improves the filtration effect.

[0015] 3. After the filter component of this application brings the debris to the top, it falls into the collection box through the gap in the conveyor chain. The collection box can be easily switched, and the old and new collection boxes are in close contact during the switch to avoid the leakage of debris.

[0016] 4. The protrusions on the outer casing of this application cooperate with the filter plate. By utilizing the elasticity of the filter plate, the filter plate vibrates when it contacts and detaches from the protrusions, automatically shaking off debris and improving the efficiency of debris cleaning.

[0017] 5. This application, through the cooperation of control levers and limit hooks, facilitates the movement of the conveyor chain by the staff and stabilizes the position of the filter components, ensuring the stable operation of filtration and collection. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] like Figures 1 to 6 As shown, a multi-stage filtration device for municipal road drainage includes a housing 101. A connecting pipe 102 and a support plate 103 are fixedly mounted on the housing 101. Two conveyor chains 104 are slidably mounted on the support plate 103. The conveyor chains 104 are located on the two end faces of the support plate 103 and are slidably connected to the housing 101. Multiple grooves are provided on the conveyor chains 104, and multiple sets of filter components are provided on the grooves. Each filter component includes one first filter plate 106, one second filter plate 107, and one third filter plate 108. A collection box 105 is slidably mounted on the housing 101 and is also slidably connected to the support plate 103.

[0028] Specifically, this application is used for municipal road sewer pipe openings. When in use, the connecting pipe 102 is inserted into the sewer opening, and then the sewer inlet is blocked by the outer shell 101, so that water can only enter the sewer through the channel inside the outer shell 101. Thus, sewage can be filtered through the multiple filter components installed inside the outer shell 101 to avoid clogging.

[0029] Specifically, only two sets of multiple filter components are used for filtration at the same time, and the set at the inlet plays the main filtration role. When a large amount of debris is blocked by this set of filter components, the conveyor chain 104 can be controlled to move on the support plate 103 to change the position of the filter components. This allows the filter components that collect the debris to move upwards, while the next set of filter components moves to the water inlet of the outer casing 101 to continue filtration. During this process, drainage and filtration are not interrupted.

[0030] When the filter assembly moves the debris upwards, the outer casing 101 blocks the sides of the filter assembly, and the conveyor chain 104 blocks the inside, preventing the debris from falling off. After moving to the top, the upper end of the conveyor chain 104 has a notch, allowing the debris to fall through and enter the collection box 105 for collection. When the collection box 105 is full, a new collection box 105 can be aligned with the old collection box 105. Then, the new collection box 105 is pushed and pulled from the other side to move it out of the outer casing 101 and the conveyor chain 104, thus switching the collection box 105. During this process, the new and old collection boxes 105 are in close contact, preventing new debris from falling between the two collection boxes 105 and becoming uncollectible during replacement.

[0031] like Figures 3 to 6 As shown, the first filter plate 106, the second filter plate 107 and the third filter plate 108 all include a filter plate and a mounting rod. The mounting rod slides on the groove of the conveyor chain 104. The filter plate has an arc-shaped structure and is elastic.

[0032] Specifically, the diameter of the filter holes on the first filter plate 106, the second filter plate 107, and the third filter plate 108 decreases step by step to achieve graded filtration. During filtration, the arc-shaped structure improves the collection capacity of impurities and minimizes the fall of impurities when they are moved to the top, thereby improving the efficiency of impurity retrieval.

[0033] like Figure 1 and Figure 3 As shown, the outer shell 101 is provided with two sets of protrusions 109, and each set of protrusions 109 is provided with multiple protrusions.

[0034] Specifically, the two sets of protrusions 109 correspond to each other and simultaneously contact and detach from the filter assembly. When the filter plate of the filter assembly contacts the protrusions 109 on both sides, the arc-shaped surface of the protrusions 109 causes the filter plate to bend, that is, to bend further along the arc-shaped structure of the filter plate. After detaching from the protrusions 109, the filter plate quickly resets due to its elasticity, causing the debris on the filter plate to vibrate. The debris falls off the filter plate and enters the collection box 105 for collection through the gap in the conveyor chain 104.

[0035] like Figure 4 and Figure 5 As shown, a plurality of control rods 110 are fixedly installed on the conveyor chain 104 for controlling the movement of the conveyor chain 104 on the support plate 103.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, a limit hook 111 is rotatably provided on the outer casing 101 to limit the movement of the control rod 110.

[0037] Specifically, multiple control levers 110 are provided on the side of the conveyor chain 104 away from the support plate 103. Each control lever 110 moves within a housing on the outer casing 101, and this portion of the housing has an opening corresponding to the notch in the conveyor chain 104, exposing the control levers 110 to the outside in this space. Operators can directly control the control levers 110, thereby moving the conveyor chain 104 on that side on the support plate 103. The conveyor chains 104 on both sides are connected by multiple crossbars to achieve synchronous movement. Figure 4 As shown, when the control rod 110 rotates clockwise, it automatically disengages from the limit hook 111. After moving, under the action of the water flow, it pushes the filter assembly, thereby causing the conveyor chain 104 to rotate counterclockwise on the support plate 103. Then, the new control rod 110 approaches and contacts the limit hook 111, pushing the limit hook 111 to rotate. When the control rod 110 enters the groove of the limit hook 111, it pulls the control rod 110 through the groove, thereby limiting the movement of the control rod 110, and thus limiting the movement of the conveyor chain 104 and the filter assembly, stabilizing the position of the filter assembly, and continuing to filter and collect.

[0038] like Figure 2 As shown, the collection box 105 is provided with a groove for workers to lift the collection box 105.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
