Description

Technical Field

[0001] The utility model relates to the field of sealing of the water inlet of a differential pressure filter, and particularly relates to a sealing structure of a differential pressure filter. Background Art

[0002] Sewage treatment filters are applicable to the separation of solid suspended particles in liquids, especially toxic media. Sewage treatment filters mainly treat sewage so that it can be recycled. However, the existing filters cannot meet people's needs. There are certain drawbacks in the use of existing filters. First of all, in the use process, the installation of existing filters is relatively cumbersome, and the price is relatively high. The later maintenance is more troublesome, which increases the working intensity of the staff. Moreover, existing filters can only remove impurity particles in water, cannot treat bacteria inside the sewage, and cannot observe the working state of the filter, which brings certain adverse effects to people's use process. Therefore, a differential pressure type non-powered filter is needed;

[0003] According to the application number: CN202121337918.7, a differential pressure type non-powered filter is provided. In this scheme, through the arranged chlorine dioxide storage box, chlorine dioxide disinfection device and feed valve, the chlorine dioxide storage box can be filled with chlorine dioxide materials before use. Before the equipment runs, the chlorine dioxide materials in the chlorine dioxide storage box are sent into the chlorine dioxide disinfection device through the feed valve. During use, the water in the filter can be disinfected by the chlorine dioxide disinfection device, and protozoa, spores, molds, algae and biofilms in the water can be killed. And it does not generate chlorophenols and trihalomethanes, and can oxidize many organic compounds, thereby reducing the toxicity of water. However, when the filter is in use, at the connection of its water inlet, it is generally sealed by a single rubber gasket to prevent sewage leakage when connecting sewage. However, after long-term use, the single rubber gasket is easily corroded, and the gasket will also be contaminated by sewage when contacting the sewage, and then bacteria will breed. When mixed with sewage again, it may increase the toxicity of the sewage. Therefore, when treating the sewage subsequently, stronger treatment capabilities are required, which is not conducive to saving sewage treatment materials.

[0004] Therefore, a sealing structure of a differential pressure filter is needed. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present utility model is to provide a sealing structure for a differential pressure filter. The antibacterial copper ring is fixed by a connecting ring, and the antibacterial copper ring cooperates with the protective housing to threadedly connect the water inlet pipe and the external pipeline. Among them, antibacterial copper is a metal copper material with antibacterial properties. By combining copper ions with the proteins of bacteria, the bacteria lose their activity, thereby achieving an antibacterial effect. Therefore, when in contact with sewage, antibacterial copper can exert its antibacterial effect to prevent the growth of bacteria due to being contaminated by sewage when in contact with sewage during sealing.

[0006] The above technical object of the present utility model is achieved through the following technical solutions:

[0007] A sealing structure for a differential pressure filter, comprising a filter main body.

A seal is installed at the bottom end of the water inlet pipe, and an external pipeline is installed at the bottom end of the seal. The seal is threadedly connected to both the water inlet pipe and the external pipeline.

[0008] The cooperation of the water inlet pipe and the water outlet pipe facilitates the external water flow to pass through the filter main body, enabling the filter main body to purify and filter the water body. Among them, the seal facilitates the connection of the water inlet pipe and the external pipeline, enabling the external water source to flow into the filter main body through the water inlet pipe and the external pipeline. The seal seals the connection part between the water inlet pipe and the external pipeline to prevent leakage when the external water source flows through.

[0012] Furthermore, an antibacterial copper ring is fixedly connected to the inner wall of the connecting ring. The antibacterial copper ring is adapted to the protective housing, and the antibacterial copper ring is threadedly connected to both the water inlet pipe and the external pipeline.

[0013] The antibacterial copper ring is fixed by a connecting ring. The antibacterial copper ring and the protective shell cooperate to threadedly connect the water inlet pipe and the external pipeline. Among them, antibacterial copper is a metal copper material with antibacterial effects. By binding copper ions to the proteins of bacteria, the bacteria are inactivated, thereby achieving the antibacterial effect. Therefore, when in contact with sewage, antibacterial copper can exert its antibacterial effect to prevent further bacterial growth due to being contaminated by sewage when making a seal.

[0014] Furthermore, a plurality of chutes arranged at equal intervals are provided on the inner wall of the antibacterial copper ring, and the chutes are adapted to the first sealing gasket.

[0015] Furthermore, the first sealing gasket includes a sealing ring. The sealing rings are all adapted to the protective shell, the connecting ring, and the antibacterial copper ring. The sealing ring is installed on the outer wall of the antibacterial copper ring and is located at the top of the connecting ring and fits with the protective shell.

[0016] Furthermore, a sliding block is fixedly connected to the inner wall of the sealing ring. The sliding block is adapted to the chute. A clamping block is fixedly connected to the inner wall of the sliding block. The clamping block is adapted to the chute and fits with the antibacterial copper ring.

[0017] The chute facilitates the installation of the sliding block, and thus facilitates the installation of the sealing ring. The clamping block restricts the movement of the sliding block, thereby restricting the movement of the sealing ring, making the sealing ring more stable when being installed. The sealing ring improves the sealing performance of the connecting cylinder and prevents sewage leakage.

It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0028] Refer to Figure 1 As shown, it is a sealing structure of a differential pressure filter in a preferred embodiment of the present utility model, including a filter main body 1. One end of the filter main body 1 is fixedly connected with a water inlet pipe 2, and the end of the filter main body 1 far from the water inlet pipe 2 is fixedly connected with a water outlet pipe 3. A seal 4 is installed at the bottom end of the water inlet pipe 2, and an external pipeline 5 is installed at the bottom end of the seal 4. The seal 4 is threadedly connected to both the water inlet pipe 2 and the external pipeline 5.

[0029] The cooperation of the water inlet pipe 2 and the water outlet pipe 3 facilitates the external water flow to pass through the filter main body 1, enabling the filter main body 1 to purify and filter the water body. Among them, the seal 4 facilitates the connection between the water inlet pipe 2 and the external pipeline 5, allowing the external water source to flow into the filter main body 1 through the water inlet pipe 2 and the external pipeline 5. The seal 4 seals the connection part between the water inlet pipe 2 and the external pipeline 5 to prevent leakage when the external water source flows through.

[0030] Refer to Figure 2 As shown, the seal 4 includes a connecting cylinder 401. A first gasket 402 is installed inside the connecting cylinder 401, and a second gasket 403 is installed inside the connecting cylinder 401. The second gasket 403 and the first gasket 402 are symmetrically distributed, and the second gasket 403 and the first gasket 402 have the same structure.

[0031] The connecting cylinder 401 connects the water inlet pipe 2 and the external pipeline 5, and the second gasket 403 and the first gasket 402 respectively seal the water inlet pipe 2 and the external pipeline 5 to prevent leakage when the water body flows.

[0032] Refer to Figure 4 As shown, the connecting cylinder 401 includes a protective housing 40101. The protective housing 40101 is threadedly connected to the water inlet pipe 2 and the external pipeline 5 respectively. A connecting ring 40104 is fixedly connected inside the protective housing 40101.

[0033] An antibacterial copper ring 40102 is fixedly connected to the inner wall of the connecting ring 40104. The antibacterial copper ring 40102 is adapted to the protective housing 40101 and is threadedly connected to the water inlet pipe 2 and the external pipeline 5 respectively.

[0034] The antibacterial copper ring 40102 is fixed by the connecting ring 40104. The antibacterial copper ring 40102 and the protective housing 40101 cooperate to threadedly connect the water inlet pipe 2 and the external pipeline 5. Among them, antibacterial copper is a metal copper material with antibacterial effects. By combining copper ions with the proteins of bacteria, the bacteria lose their activity, thus achieving the antibacterial effect. Therefore, when in contact with sewage, antibacterial copper can exert its antibacterial effect to prevent further bacterial growth due to being contaminated by sewage when making a seal.

[0035] A plurality of chutes 40103 arranged at equal intervals are formed in the inner wall of the antibacterial copper ring 40102. The chutes 40103 are adapted to the first sealing gasket 402.

[0036] Refer to Figure 3 As shown, the first sealing gasket 402 includes a sealing ring 40201. The sealing ring 40201 is adapted to the protective housing 40101, the connecting ring 40104, and the antibacterial copper ring 40102 respectively. The sealing ring 40201 is installed on the outer wall of the antibacterial copper ring 40102, located at the top of the connecting ring 40104, and fits with the protective housing 40101.

[0037] A slider 40202 is fixedly connected to the inner wall of the sealing ring 40201. The slider 40202 is adapted to the chute 40103. A clamping block 40203 is fixedly connected to the inner wall of the slider 40202. The clamping block 40203 is adapted to the chute 40103 and fits with the antibacterial copper ring 40102.

[0038] The chute 40103 facilitates the installation of the slider 40202, and thus facilitates the installation of the sealing ring 40201. The clamping block 40203 restricts the movement of the slider 40202, thereby restricting the movement of the sealing ring 40201, making the sealing ring 40201 more stable when being installed. The sealing ring 40201 improves the sealing performance of the connecting cylinder 401 and prevents sewage leakage.

[0039] Working principle: The first gasket 402 and the sealing ring 40201 are installed on the antibacterial copper ring 40102 through the cooperation of the slider 40202 and the chute 40103. The clamping block 40203 restricts the movement of the slider 40202, thereby restricting the movement of the sealing ring 40201, making the sealing ring 40201 more stable when being installed. Then, the second gasket 403 is installed on the antibacterial copper ring 40102 in the same way. Then, the antibacterial copper ring 40102 is fitted with the protective housing 40101 to thread-connect the water inlet pipe 2 and the external pipeline 5. Then, the external water source is connected, so that the external water source can enter the filter main body 1. After the filter main body 1 filters the sewage, it is discharged through the water outlet pipe 3. Among them, antibacterial copper is a metal copper material with antibacterial effect. By combining copper ions with the proteins of bacteria, the bacteria lose their activity, thus achieving the antibacterial effect. Therefore, when in contact with sewage, antibacterial copper can play its antibacterial role to prevent further bacterial growth due to being contaminated by sewage when making a seal and coming into contact with sewage.
