Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, and particularly relates to a frame structure for a rainwater inlet filter brick. Background Art

[0002] A rainwater inlet filter brick is a filtering device used in the urban drainage system. It is usually installed at the entrance of the rainwater inlet to intercept and filter solid debris flowing into the rainwater system, such as leaves, plastic bags, sediment, etc. In this way, by arranging rainwater inlet filter bricks, the risk of sewer blockage can be reduced, the water environment can be protected, and at the same time, the efficiency of the drainage system can be improved.

[0003] Among them, rainwater inlet filter bricks are usually made of durable materials, such as concrete, plastic or metal, and are designed with a specific pore structure to allow water flow through while intercepting solid waste. When designing and selecting rainwater inlet filter bricks, the following factors need to be considered: filtration efficiency: the filter bricks need to be able to effectively intercept solid waste of various sizes; durability: the filter bricks should be able to withstand long-term physical wear and chemical erosion; maintenance convenience: the filter bricks should be designed to be easy to clean and maintain to ensure long-term effective operation; cost-effectiveness: the cost of the filter bricks should match the functions and benefits they provide.

[0004] For example, a rainwater inlet filter brick and a sewage interception device are disclosed in Chinese patent document CN219569116U. The brick body of the rainwater inlet filter brick is embedded in the frame. The two opposite surfaces of the brick body not covered by the edge form an inlet end face and a drainage end face. And, reinforcing ribs are embedded inside the brick body, and the reinforcing ribs are arranged in a staggered manner inside the brick body to form a reinforcing grid, so as to improve the uniformity of the overall stress of the brick body and facilitate the cleaning and maintenance of the brick body.

[0005] However, in the actual use process of the above rainwater inlet filter brick, due to the uniform distribution of the reinforcing grid inside the brick body, it is difficult for the fillers on both sides of the reinforcing grid to be tightly combined when pressing the brick body, which in turn affects the overall structural strength of the brick body. In addition, the reinforcing grid is located between the inlet end face and the drainage end face, reducing the actual filtering end face of the brick body, which in turn affects the filtering ability and filtering effect of the brick body. Summary of the Invention

[0006] The purpose of the utility model is to provide a frame structure during the use of the rainwater inlet filter brick to improve the overall structural strength of the brick body and enhance the filtering ability and filtering effect of the brick body.

[0007] The technical problem is: reducing the influence of the internal reinforcing grid on the filtering ability and the overall strength of the filler,

[0008] To achieve the above purpose, the utility model proposes the following solutions:

[0009] A frame structure for a rainwater inlet filter brick, comprising a border and an embedding body;

[0010] A placement cavity for accommodating the brick body of the rainwater inlet filter brick is arranged inside the border, and the embedding body is located in the placement cavity;

[0011] The embedding bodies are arranged along the edge of the placement cavity, and the embedding bodies are connected to the inner wall of the border.

[0012] Among them, the brick body of the rainwater inlet filter brick is located in the placement cavity, and the embedding body is embedded in the brick body. Through its own strength and rigidity, the embedding body provides additional support for the border. The embedding body also helps to ensure the stable positioning of the brick body in the border, avoiding the movement or inclination of the brick body under the action of water flow, thus ensuring the continuity and consistency of the filtering effect. Moreover, the embedding body also helps to reduce the structural stress borne by the brick body and the border, thereby contributing to extending the service life of the rainwater inlet filter brick. In addition, the embedding bodies are arranged along the edge of the placement cavity, reducing the overlapping area between it and the filtering end face of the brick body, and further improving the filtering capacity and filtering effect of the brick body.

[0013] Preferably, the embedding body is a retaining piece, and a plurality of retaining pieces are arranged along the edge of the placement cavity, and the retaining pieces are connected to the inner wall of the border.

[0014] Preferably, the embedding body is an annular inner frame, and the side wall of the annular inner frame is connected to the inner wall of the border.

[0015] Preferably, the retaining piece is a rectangular piece.

[0016] Preferably, the retaining piece is a rectangular strip.

[0017] Preferably, the retaining piece is an L-shaped piece.

[0018] Preferably, the retaining piece is a T-shaped piece.

[0019] Preferably, the embedding body includes a retaining piece and an annular inner frame. A plurality of retaining pieces are arranged along the edge of the placement cavity, and the retaining pieces are connected to the inner wall of the border. The annular inner frame is located on one side of the retaining piece, and the side wall of the annular inner frame is connected to the inner wall of the border.

[0020] Preferably, a handle is arranged on the outer wall of the border. With this arrangement, the handle facilitates the user to grasp the border, and thus facilitates applying a pulling force to the brick body through the border. During maintenance, it is beneficial to take out the brick body as a whole for cleaning, further reducing the operation difficulty of maintenance.

[0021] Preferably, elastic ribs are provided on the outer wall of the frame. With this arrangement, the elastic ribs are used to form an elastic support structure between the frame and the installation position, facilitating the installation and removal of the rainwater inlet filter brick. During installation, they are used to compensate for the gaps caused by thermal expansion and contraction or installation errors, thereby further enhancing the sealing effect and improving the filtering effect of the brick body.

[0022] Compared with the prior art, the frame structure for a rainwater inlet filter brick provided by the present utility model has the following substantial features and improvements:

[0023] 1. The frame structure for the rainwater inlet filter brick uses the frame to protect the edge of the brick body, arranges the inserts along the edge of the placement cavity, reducing the overlapping area between it and the filtering end face of the brick body, further enhancing the filtering capacity and filtering effect of the brick body. The inserts are embedded in the brick body, which is conducive to ensuring the stable positioning of the brick body within the frame, preventing the brick body from moving or tilting under the action of water flow, thus ensuring the continuity and consistency of the filtering effect. Moreover, the inserts are also conducive to reducing the structural stress borne by the brick body and the frame, thereby facilitating the extension of the service life of the rainwater inlet filter brick;

[0024] 2. The frame structure for the rainwater inlet filter brick arranges inserts along the inner edge of the frame, using the inserts to enhance the structural strength of the frame. Especially during the forming of the frame, it avoids the frame from deforming into a parallelogram or being distorted, thus ensuring the forming accuracy of the frame, and improving the assembly accuracy between the rainwater inlet filter brick and the rainwater inlet. This is beneficial to both the installation and maintenance of the rainwater inlet filter brick and the sealing effect at the assembly location. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following combines the drawings to describe the detailed implementation manners of the present utility model in detail.

[0039] As Figures 1 - 12 Shown, in the embodiment of the present utility model, a frame structure for a rainwater inlet filter brick is proposed, aiming to optimize the assembly structure of the existing rainwater inlet filter brick, improve the overall structural strength of the brick body, and enhance the filtering capacity and filtering effect of the brick body.

[0040] In the actual use process of the existing rainwater inlet filter brick, the strengthening grids are evenly distributed inside the brick body. When pressing the brick body, it is difficult for the fillers on both sides of the strengthening grids to be tightly combined, thus affecting the overall structural strength of the brick body. Moreover, the strengthening grids are located between the water inlet end face and the water drainage end face, reducing the actual filtering end face of the brick body, and thus affecting the filtering capacity and filtering effect of the brick body.

[0041] A frame structure for a rainwater inlet filter brick proposed in an embodiment of the present utility model includes a border 1 and an embedding body. A placement cavity 2 for accommodating the brick body of the rainwater inlet filter brick is provided inside the border 1. The embedding body is located within the placement cavity 2. The embedding bodies are arranged along the edge of the placement cavity 2. The embedding body is connected to the inner wall of the border 1. This frame structure uses the border 1 to protect the edge of the brick body. By arranging the embedding bodies along the edge of the placement cavity 2, the overlapping area between it and the filtering end face of the brick body is reduced, further improving the filtering capacity and effect of the brick body. The embedding body is embedded in the brick body, which helps to ensure the stable positioning of the brick body within the border 1, preventing the brick body from moving or tilting under the action of water flow, thus ensuring the continuity and consistency of the filtering effect. Moreover, the embedding body is also beneficial for reducing the structural stress borne by the brick body and the border 1, and further beneficial for extending the service life of the rainwater inlet filter brick.

[0042] Among them, the brick body is made by mixing zeolite and activated carbon in proportion and pressing. The raw materials (zeolite and activated carbon mixed in a certain proportion) are screened by a screening machine to remove materials and impurities with particle sizes that do not meet the requirements. After screening, methods such as cleaning and ultrasonic treatment are used to remove impurities on the surface of the materials. The cleaned and ultrasonically treated materials are placed in an oven and dried at a constant temperature of 50 °C for 10 h. After drying, it is naturally cooled to room temperature. The raw materials and the binder are mixed in a certain proportion and continuously stirred strongly until the binder is evenly mixed with the raw materials. First, the integrally formed embedding body and the border 1 are placed in a mold, and then the mixture is poured into the mold, filled with the mold, and oscillated evenly. It is made by pressing with an object and placing it at room temperature for twelve hours. Embodiment

[0043] As Figure 1 Combined Figure 2 As shown, a frame structure for a rainwater inlet filter brick includes a border 1 and a baffle 3. A placement cavity 2 for accommodating the brick body of the rainwater inlet filter brick is provided inside the border 1. The baffle 3 is located within the placement cavity 2. The baffle 3 is arranged along the edge of the placement cavity 2. The baffle 3 is connected to the inner wall of the border 1.

[0044] For example, as Figure 2 shown, the baffle 3 is a rectangular sheet. The number of rectangular sheets is selected according to the size of the border 1 and actual requirements.

[0045] As Figure 1 shown, a handle 5 is provided on the outer wall of the border 1. With this setting, the handle 5 facilitates the user to grasp the border 1, and thus facilitates applying a pulling force to the brick body through the border 1. During maintenance, it is beneficial to take out the brick body as a whole for cleaning, further reducing the operation difficulty of maintenance.

[0046] An elastic rib 6 is provided on the outer wall of the frame 1. With such a setting, the elastic rib 6 is used to form an elastic support structure between the frame 1 and the installation position, facilitating the installation and removal of the rainwater inlet filter brick. During installation, it is used to compensate for the gaps or installation errors 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 6 is made of rubber or plastic. Embodiment

The embedding bodies are arranged along the edge of the placement cavity 2, reducing the overlapping area between it and the filtering end face of the brick body, and further improving the filtering capacity and filtering effect of the brick body.

[0053] In addition, the frame structure for the rainwater inlet filter brick improves the structural strength of the frame 1 by arranging the embedding bodies on the inner edge of the frame 1. Especially when the frame 1 is formed, it avoids the deformation of the frame 1 into a parallelogram or torsion deformation, thus ensuring the forming accuracy of the frame 1, and thereby improving the assembly accuracy between the rainwater inlet filter brick and the rainwater inlet. This is beneficial to both the installation and maintenance of the rainwater inlet filter brick and the sealing effect at the assembly.
