Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a multi-layer filter. Background Technology

[0002] Multi-layer filters, also known as stacked filters or multi-stage filters, are devices that remove contaminants of different sizes and types through multiple filter layers in sequence. By using multiple layers of filter media such as coarse filtration, fine filtration, and terminal filtration, contaminants of different sizes are removed step by step to ensure efficient filtration. Each layer of filter media shares the filtration task and is not prone to premature clogging. The maintenance frequency is low, reducing the cost and time of replacing filter media.

[0003] For example, Chinese Patent Application No. 201920687027.0 discloses a multi-layer filter, including a housing and a filter element assembly disposed within the housing. The housing has a cover and a base at both ends. The cover has an oil inlet, and the base has an oil outlet. The filter element assembly includes a frame and several filter elements disposed within the frame. The inlet end of the frame is connected to the oil inlet, and the outlet end of the frame is connected to the oil outlet. The filter elements are arranged sequentially and at intervals within the frame from the oil inlet to the oil outlet. This utility model provides a multi-layer filter with high filtration efficiency and simple structure.

[0004] However, in the aforementioned multi-layer filter, the lack of reinforcement and restraint between the top and bottom plates after installation allows the internal filter layers to deform, misalign, or become damaged under pressure, affecting the stability of the filtration channel. Therefore, those skilled in the art have provided a multi-layer filter to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layer filter includes a multi-layer filter body, a bottom plate installed at the bottom of the multi-layer filter body, a top plate installed at the top of the multi-layer filter body, a connecting cylinder extending to the outside fixed inside the multi-layer filter body, a reinforcing mechanism provided on the outside of the connecting cylinder, and stabilizing mechanisms installed on the outside of both the top plate and the bottom plate.

[0008] The reinforcement mechanism includes a reinforcement connecting pad, a first galvanized semi-threaded column fixed to the outer side of the reinforcement connecting pad, fixing blocks fixed to the outer sides of both the top plate and the bottom plate, a fixing metal rod installed on one side of the fixing block, a limit pad fixed to the outer side of the fixing metal rod, a reinforcement metal pad connected to the outer side of the fixing metal rod via a bearing, a second galvanized semi-threaded column fixed to the outer side of the reinforcement metal pad, and a galvanized nut threadedly connected to the outer sides of both the second and first galvanized semi-threaded columns.

[0009] As a further embodiment of this utility model: the stabilizing mechanism includes a fixed shell, a supporting spring is provided on one inner wall of the fixed shell, a movable plate is connected to one end of the supporting spring, a reinforcing block is fixed on one side of the movable plate, a limit rod is installed on the side of the movable plate away from the reinforcing block, and a limit sleeve is installed on one inner wall of the fixed shell.

[0010] As a further improvement of this utility model, a limiting groove is provided inside the limiting sleeve, and the size of the limiting groove is adapted to the size of the limiting rod.

[0011] As a further improvement of this utility model, the interior of the fixing shell is provided with a through hole, the size of which is adapted to the size of the reinforcing block.

[0012] As a further embodiment of this utility model: reinforcing connecting pads are fixed on the outer sides of both the top plate and the bottom plate, and the lower bottom surface of the reinforcing metal pad is in contact with the upper top surface of the reinforcing connecting pad.

[0013] As a further improvement of this utility model: the inner wall of the reinforcing connecting pad is fitted to the outer side of the connecting cylinder, and the outer side of the galvanized nut is provided with anti-slip texture.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This device is equipped with a reinforcement mechanism. The outer side of the connecting cylinder is reinforced and limited by the reinforcement connecting pad, which improves the connection stability between the top plate and bottom plate and the connecting cylinder. It can prevent the internal filter layer from deforming, misaligning or being damaged under pressure, ensuring the stability of the filtration channel, high and stable impurity interception efficiency, and providing uniform clamping force for the filter media of the multi-layer filter body. This ensures that the liquid passes through the multi-layer filter media evenly, achieves progressive filtration, and ensures the multi-layer filtration effect.

[0016] 2. By setting a stabilizing mechanism, one end of the reinforcing block is made to fit against the corresponding surface of the installation part of the multi-layer filter body. This serves to provide auxiliary support and reinforcement to the installation part after the multi-layer filter body is installed, ensuring the stability of the installation structure of the multi-layer filter body, and will not affect the normal installation, disassembly and replacement of the multi-layer filter body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a multi-layer filter includes a multi-layer filter body 1, a bottom plate 2 installed at the bottom of the multi-layer filter body 1, a top plate 3 installed at the top of the multi-layer filter body 1, a connecting cylinder 4 extending to the outside fixed inside the multi-layer filter body 1, a reinforcing mechanism 5 provided on the outside of the connecting cylinder 4, and a stabilizing mechanism 6 installed on the outside of both the top plate 3 and the bottom plate 2.

[0024] The reinforcement mechanism 5 includes a reinforcement connecting pad 51. A first galvanized semi-threaded post 52 is fixed to the outer side of the reinforcement connecting pad 51. Fixing blocks 53 are fixed to the outer sides of both the top plate 3 and the bottom plate 2. A fixing metal rod 54 is installed on one side of the fixing block 53. A limit pad 55 is fixed to the outer side of the fixing metal rod 54. A reinforcement metal pad 56 is connected to the outer side of the fixing metal rod 54 via a bearing. A second galvanized semi-threaded post 57 is fixed to the outer side of the reinforcement metal pad 56. A galvanized nut 58 is threadedly connected to the outer sides of the second galvanized semi-threaded post 57 and the first galvanized semi-threaded post 52. The reinforcement connecting pad 51 is fixed to the outer side of both the top plate 3 and the bottom plate 2. The lower bottom surface of the reinforcement metal pad 56 is in contact with the upper top surface of the reinforcement connecting pad 51. The inner wall of the reinforcement connecting pad 51 is in contact with the outer side of the connecting cylinder 4. The outer side of the galvanized nut 58 is provided with anti-slip texture. After the top plate 3 and the bottom plate 2 are installed on the top and bottom of the multi-layer filter body 1 respectively, they can be moved and fixed. The reinforcing metal pad 56 on the outside of the metal rod 54 rotates, so that the corresponding surface of the reinforcing metal pad 56 is in contact with the corresponding surface of the reinforcing connecting pad 51 on the outside of the top plate 3 and the bottom plate 2, and the second galvanized semi-threaded post 57 on the outside of the reinforcing metal pad 56 is in contact with the corresponding surface of the first galvanized semi-threaded post 52. Then, the galvanized nut 58 is threaded to the first galvanized semi-threaded post 52 and the second galvanized semi-threaded post 57, so that the corresponding surface of the galvanized nut 58 is pressed against the outside of the reinforcing metal pad 56, which facilitates the installation and fixing of the reinforcing metal pad 56, ensuring the stable connection between the reinforcing connecting pad 51, the bottom plate 2 and the top plate 3. By reinforcing and limiting the outside of the connecting cylinder 4 through the reinforcing connecting pad 51, the connection stability between the top plate 3 and the bottom plate 2 and the connecting cylinder 4 is improved, which can prevent the internal filter layer from deforming, misaligning or being damaged under pressure, ensuring the stability of the filtration channel, high and stable impurity interception efficiency, and providing uniform clamping force for the filter material of the multi-layer filter body 1.

[0025] In one embodiment of this utility model, the stabilizing mechanism 6 includes a fixed shell 61. A support spring 62 is provided on one inner wall of the fixed shell 61. One end of the support spring 62 is connected to a movable plate 63. A reinforcing block 64 is fixed on one side of the movable plate 63. A limiting rod 65 is installed on the side of the movable plate 63 away from the reinforcing block 64. A limiting sleeve 66 is installed on one inner wall of the fixed shell 61. A limiting groove is opened inside the limiting sleeve 66. The size of the limiting groove is adapted to the size of the limiting rod 65. A through hole is opened inside the fixed shell 61. The size of the through hole is adapted to the size of the reinforcing block 64.

[0026] The working principle of this utility model is as follows: This device is equipped with a reinforcing mechanism 5. After the top plate 3 and the bottom plate 2 are respectively installed on the top and bottom of the multi-layer filter body 1, the reinforcing metal pad 56 on the outside of the fixed metal rod 54 can be rotated to make the corresponding surface of the reinforcing metal pad 56 fit with the corresponding surface of the reinforcing connecting pad 51 on the outside of the top plate 3 and the bottom plate 2, and to make the second galvanized semi-threaded post 57 on the outside of the reinforcing metal pad 56 fit with the corresponding surface of the first galvanized semi-threaded post 52. Then, the galvanized nut 58 is threaded to the first galvanized semi-threaded post 52 and the second galvanized semi-threaded post 57, so that the corresponding surface of the galvanized nut 58 is pressed against the outside of the reinforcing metal pad 56, which facilitates the installation and fixing of the reinforcing metal pad 56, ensuring the stable connection between the reinforcing connecting pad 51, the bottom plate 2 and the top plate 3. By reinforcing and limiting the outside of the connecting cylinder 4 through the reinforcing connecting pad 51, the connection stability between the top plate 3 and the bottom plate 2 and the connecting cylinder 4 is improved, which can prevent The internal filter layer deforms, misaligns, or is damaged under pressure, ensuring the stability of the filtration channel and high and stable impurity interception efficiency. It provides uniform clamping force to the filter media of the multi-layer filter body 1, ensuring that the liquid passes through the multi-layer filter media evenly, achieving progressive filtration and ensuring the multi-layer filtration effect. With the stabilizing mechanism 6, after the multi-layer filter body 1 is installed in the corresponding position, the support spring 62 in the fixed shell 61 pushes the moving plate 63, causing the limiting rod 65 on one side of the moving plate 63 to move. One end of the limiting rod 65 moves within the limiting sleeve 66, playing a guiding role. At the same time, the moving plate 63 drives the reinforcing block 64 to move, allowing one end of the reinforcing block 64 to fit against the corresponding surface of the installation part of the multi-layer filter body 1. This serves to provide auxiliary support and reinforcement to the installation part after the multi-layer filter body 1 is installed, ensuring the stability of the installation structure of the multi-layer filter body 1, and will not affect the normal installation, disassembly, and replacement of the multi-layer filter body 1.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
