Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage equipment, in particular to a horizontal pull-out filter element. Background Art
[0002] The rainwater filter brick is a key urban drainage system filtration device, usually installed at the entrance of the rainwater inlet, designed to intercept and filter various solid debris flowing into the rainwater system, such as leaves, plastic bags and sediment. The use of rainwater filter bricks can significantly reduce the risk of sewer blockage, protect the water environment, and improve the operating efficiency of the entire drainage system.
[0003] Stormwater filter bricks are generally made of durable materials such as concrete, plastic or metal. These materials can not only withstand long-term physical wear and chemical erosion, but also form a specific pore structure in the design, so that it can effectively filter solid waste while allowing water to flow smoothly. In order to ensure the effectiveness and durability of stormwater filter bricks, the following key factors need to be considered in the design and selection:
[0004] 1. Filtration efficiency: The rainwater filter brick must be able to effectively intercept solid waste of various sizes to ensure that only clean water enters the drainage system. This requires a reasonable pore structure to balance water flow and debris retention.
[0005] 2. Durability: Since the rainwater filter bricks are exposed to the natural environment for a long time and need to withstand various physical wear and chemical erosion, the durability of the material is very important. Choosing appropriate materials and design structures can extend the service life of the filter bricks and reduce maintenance frequency and costs.
[0006] 3. Maintenance convenience: The rainwater inlet filter brick should be designed to be easy to clean and maintain to ensure its long-term effective operation. Convenient maintenance methods can not only reduce maintenance costs, but also improve work efficiency and reduce system downtime.
[0007] The inventor has developed a rainwater inlet filter brick and a sewage interception device, which improves the existing rainwater inlet filter brick structure. The brick body of the rainwater inlet filter brick is embedded in the frame to form a water inlet end face and a drainage end face. Reinforcement ribs are embedded inside the brick body, and these reinforcement ribs are arranged in a staggered manner inside the brick body to form a reinforced grid structure. This design not only improves the uniformity of the overall force of the brick body, but also enhances its structural strength, making the brick body more durable.
[0008] However, in actual use of the above-mentioned rainwater inlet filter bricks, since the rainwater inlet filter bricks are first made by placing the integrally formed reinforcement ribs and frames into a mold, then pouring the mixture into the mold, covering the mold, and oscillating to make it uniform, the brick body and the frame are an integrated structure, which lacks flexibility in use and is difficult to replace the brick body according to actual use needs. For example, climate conditions in different seasons in the same area will affect the diffusion and sedimentation of pollutants in the atmosphere, and the impurity components contained in rainwater are different, so different filter bricks need to be replaced to adapt. When replacing, the frame needs to be replaced synchronously with the brick body, which causes waste and increases the cost of maintenance and replacement. Summary of the invention
[0009] The purpose of the utility model is to provide an improved structure for the use of rainwater inlet filter bricks, so as to facilitate the replacement and cleaning of the brick body, reduce the difficulty of maintenance, extend the service life and improve the flexibility of use.
[0010] In order to achieve the above purpose, the utility model adopts the following scheme:
[0011] A horizontal pull-out filter element comprises a filter brick and an outer frame;
[0012] The outer frame is provided with a placement cavity for accommodating the filter brick inside, the filter brick is embedded in the placement cavity, the placement cavity is provided with a water inlet and a drain, the water inlet is located on the first end face side of the filter brick, and the drain is located on the second end face side of the filter brick;
[0013] An opening for pulling out the filter brick is arranged on the side wall of the outer frame, and the opening is connected to the placement cavity.
[0014] Preferably, the water inlet is smaller than the first end surface of the filter brick, and a first limiting structure for the filter brick is formed on the outer frame.
[0015] Preferably, the drain outlet is smaller than the second end surface of the filter brick, and a second limiting structure for the filter brick is formed on the outer frame.
[0016] In this way, the first limiting structure and the second limiting structure are used to firmly fix the filter brick in the placement cavity to prevent it from shifting under the impact of water flow or other external forces. This ensures that the filter brick continues to filter effectively and avoids the reduction or failure of the filtering effect due to displacement.
[0017] Preferably, a handle is provided on the side wall of the outer frame, so that the handle is convenient for users to grasp the outer frame, further reducing the difficulty of maintenance.
[0018] Preferably, the handle and the opening are respectively located on adjacent sides of the outer frame. This arrangement facilitates the filter brick to be drawn out of the placement cavity in a horizontal posture, further reducing the difficulty of replacing the filter brick.
[0019] Preferably, the outer wall of the outer frame is provided with elastic ribs, which are arranged along the outer contour of the outer frame. In this way, the elastic ribs are used to form an elastic support structure between the frame and the installation position, which is convenient for the installation and removal of the rainwater inlet filter bricks. During installation, they are used to compensate for the gap or installation error caused by thermal expansion and contraction, thereby further improving the sealing effect and the filtering effect of the brick body.
[0020] Preferably, the filter brick is provided with rounded corners on its edges. In this way, when the filter brick and the outer frame are assembled, the rounded corners are used to guide the filter brick, further reducing the difficulty of the filter brick entering the placement cavity through the opening.
[0021] Preferably, the top and bottom of the filter brick are both provided with through grooves, and the interior of the placement cavity is provided with convex strips for matching the through grooves. With such a configuration, when the filter brick is assembled with the outer frame, the convex strips are embedded in the through grooves. For the filter brick, the convex strips are equivalent to forming a guide rail structure, further forming a guide limit for the installation position of the filter brick, ensuring the installation position accuracy of the filter brick, and further ensuring the filtering effect of the filter element.
[0022] Preferably, the outer frame is provided with a grille, which is arranged at the water inlet and the drain outlet. In this way, the grille is used to further limit the filter bricks, which is conducive to preventing the filter bricks from falling out of the placement cavity.
[0023] Compared with the prior art, the horizontal pull-out filter element provided by the utility model has the following substantial characteristics and progress: the horizontal pull-out filter element makes the replacement and cleaning of the filter bricks more convenient by arranging the filter bricks and the outer frame into a split structure, without the need for complicated disassembly work, and the maintenance personnel only need to pull out the filter bricks horizontally for cleaning or replacement, which greatly reduces the maintenance workload and time. Since the cleaning and replacement of the filter bricks are more convenient, maintenance can be carried out more frequently, reducing the risk of debris accumulation and filter element clogging, thereby extending the service life of the filter element and the overall system. In addition, different filter materials and filter brick structures can be designed according to different environments and needs, providing a more flexible filtering solution with stronger adaptability.

[0030] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.
[0031] like Figure 1-Figure 5 As shown, a horizontal pull-out filter element is proposed in the embodiment of the utility model, which is intended to facilitate the replacement and cleaning of the brick body, reduce the difficulty of maintenance, extend the service life, and improve the flexibility of use.
[0032] A horizontal pull-out filter element proposed in the embodiment of the utility model makes the replacement and cleaning of the filter bricks more convenient by arranging the filter bricks and the outer frame into a split structure. There is no need to perform complicated disassembly work. The maintenance personnel only need to pull out the filter bricks horizontally to clean or replace them, which greatly reduces the maintenance workload and time, reduces the difficulty of maintenance, prolongs the service life, and improves the flexibility of use.
[0033] like Figure 1 Combination Figure 3 As shown, a horizontal pull-out filter element includes a filter brick 1 and an outer frame 2. A placement cavity 3 for accommodating the filter brick 1 is provided inside the outer frame 2. The filter brick 1 is embedded in the placement cavity 3. The placement cavity 3 is provided with a water inlet 4 and a drain port 5. The water inlet 4 is located on the first end face side of the filter brick 1. The drain port 5 is located on the second end face side of the filter brick 1. Figure 2 As shown, an opening 6 for pulling out the filter brick 1 is provided on the side wall of the outer frame 2 , and the opening 6 is connected to the placement cavity 3 .
[0034] The water inlet 4 is smaller than the first end face of the filter brick 1, and a first limiting structure 7 for the filter brick 1 is formed on the outer frame 2. The water outlet 5 is smaller than the second end face of the filter brick 1, and a second limiting structure 8 for the filter brick 1 is formed on the outer frame 2. For example, both the first limiting structure 7 and the second limiting structure 8 are annular baffles, which form end limits for the filter brick 1.
[0035] The first limiting structure 7 and the second limiting structure 8 are used to firmly fix the filter brick 1 in the placement cavity 3 to prevent it from shifting under the impact of water flow or other external forces. This ensures that the filter brick 1 continues to filter effectively and avoids the reduction or failure of the filtering effect due to displacement. In addition, the first limiting structure 7 and the second limiting structure 8 also provide additional support for the filter brick 1, making the filter brick 1 more stable in the placement cavity 3, thereby helping to extend the service life of the filter brick 1 and the outer frame 2 and reduce the loss and damage caused by vibration or impact.
[0036] In addition, the design of the above-mentioned limiting structure can protect the edge of the filter brick 1 and reduce the possibility of edge wear and damage, thereby further extending the service life of the filter brick 1 and reducing the frequency and cost of replacement and maintenance.
[0037] like Figure 2 As shown, a handle 9 is provided on the side wall of the outer frame 2. In this way, the handle 9 is convenient for users to grasp the outer frame 2, further reducing the difficulty of maintenance.
[0038] According to a preferred embodiment of the present utility model, Figure 2 As shown, the handle 9 and the opening 6 are respectively located on adjacent sides of the outer frame 2. Such arrangement facilitates the filter brick 1 to be drawn out from the placement cavity 3 in a horizontal posture, further reducing the difficulty of replacing the filter brick 1.
[0039] like Figure 1 As shown, an elastic rib 10 is provided on the outer wall of the outer frame 2. The elastic rib 10 is arranged along the outer contour of the outer frame 2. In this way, the elastic rib 10 is used to form an elastic support structure between the frame and the installation position, which is convenient for the installation and removal of the rainwater inlet filter brick 1. During installation, it is used to compensate for the gap or installation error caused by thermal expansion and contraction, thereby further improving the sealing effect and the filtering effect of the brick body. For example, the elastic rib 10 is made of rubber or plastic.
[0040] like Figure 3 As shown, the filter brick 1 is provided with rounded corners 11 on its edges. In this way, when the filter brick 1 and the outer frame 2 are assembled, the rounded corners 11 are used to guide the filter brick 1, further reducing the difficulty of the filter brick 1 entering the placement cavity 3 through the opening 6.
[0041] like Figure 4 As shown, the top and bottom of the filter brick 1 are both provided with through grooves 12, and the interior of the placement cavity 3 is provided with convex strips for matching the through grooves 12. With such a configuration, when the filter brick 1 is assembled with the outer frame 2, the convex strips are embedded in the through grooves 12. For the filter brick 1, the convex strips are equivalent to forming a guide rail structure, further forming a guide limit for the installation position of the filter brick 1, ensuring the installation position accuracy of the filter brick 1, and further ensuring the overall filtering effect of the filter element.
[0042] In order to further improve the stability of the filter brick 1 in the placement cavity 3, as Figure 5 As shown, a grille 13 is also provided on the outer frame 2. The grille 13 is arranged at the water inlet 4 and the drain outlet 5, and is used to further limit the filter brick 1, which is beneficial to prevent the filter brick 1 from escaping from the placement cavity 3.
[0043] When a horizontal pull-out filter element proposed in the embodiment of the utility model is used, when the working condition is the first installation of the filter brick 1, the specific operation is: confirm that there are no obstacles or debris in the placement cavity 3; insert the filter brick 1 horizontally into the placement cavity 3 along the direction of the opening 6 to ensure that the filter brick 1 is completely embedded, the water inlet 4 is located on the first end face side of the filter brick 1, and the drain port 5 is located on the second end face side of the filter brick 1; ensure that the filter brick 1 is in close contact with the side wall of the outer frame 2 to prevent water from leaking from the side.
[0044] When the filter brick 1 still cannot restore the original filtering effect after multiple cleanings, or the filter brick 1 is obviously damaged, or it is necessary to replace a new filter brick 1 according to different water filtration requirements, the replacement is carried out according to the following steps: pull the old filter brick 1 horizontally out of the placement cavity 3 through the opening 6; check whether there is any residual debris or damage in the placement cavity 3, and clean and repair it if necessary; insert the new filter brick 1 horizontally into the placement cavity 3 along the direction of the opening 6 to ensure that it is correctly positioned and the water inlet 4 and the drain outlet 5 are correctly positioned.
[0045] In a horizontal pull-out filter element proposed in the embodiment of the utility model, under normal circumstances, rainwater enters the placement chamber 3 through the water inlet 4, is filtered by the filter brick 1, and is discharged from the drain outlet 5. Check the water quality of the water outlet regularly to ensure the filtering effect. If the water quality is found to be deteriorating or the water output is reduced, the filter brick 1 may need to be cleaned or replaced. Clean the filter element regularly (recommended once a month or according to the specific situation), and the specific frequency depends on the accumulation of local debris.
[0046] To clean the filter brick 1, pull out the filter brick 1 horizontally through the opening 6. This step should be performed carefully to avoid damaging the filter brick 1 or the outer frame 2. Use a high-pressure water gun or a brush to clean the debris on the surface of the filter brick 1. If the filter brick 1 is damaged or the filtering effect is significantly reduced, a new filter brick 1 should be replaced. After cleaning, insert the filter brick 1 horizontally back into the placement cavity 3 to ensure that it is in close contact with the side wall of the outer frame 2, and restore the normal working state of the water inlet and outlet 5.
[0047] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
