Description

Technical Field

[0001] This utility model relates to the field of gas pipeline filtration technology, specifically a wire mesh filter for gas pipelines that is easy to clean. Background Technology

[0002] A wire mesh filter for gas pipelines is an important device for filtering impurities from gas. When gas flows in the pipeline, it first enters the filter through the inlet. The wire mesh is woven from many fine metal or synthetic fibers, forming a dense filtration barrier. As the gas passes through the mesh, solid particles, dust, tar, and other impurities are intercepted. These impurities are larger than the mesh openings and therefore cannot pass through, thus separating from the gas. The filtered, clean gas flows out of the filter outlet and continues its transport in the pipeline.

[0003] In the existing technology, when the wire mesh filter connected to the gas pipeline needs to be cleaned, it is very inconvenient to disassemble because it is located inside the filter. Chemical cleaning can be used to clean it. After preparing a suitable chemical cleaning solution, it is injected into the inlet of the filter for soaking and cleaning, and then rinsed with clean water several times to complete the cleaning. In order to facilitate this step, reduce the impact on the filter, and enhance the cleaning effect, we propose a wire mesh filter for gas pipeline that is easy to clean. Utility Model Content

[0004] The purpose of this invention is to provide a wire mesh filter for gas pipelines that is easy to clean, so as to solve the problems existing in the prior art as described in the background.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the lifting device includes two hydraulic rods fixedly connected to the side wall of the filter body, and the extended ends of the two hydraulic rods are fixedly connected to a connecting frame, which is fixedly connected to the side wall of the motor.

[0008] Preferably, the turbulence device includes a rotating rod fixedly connected to the end of the motor output shaft, a connecting seat at the corresponding position having a through groove, and through slots being provided at the bottom of the connecting groove and the side wall of the filter body. The output shaft of the motor passes through the two through slots, allowing the rotating rod to extend into the filter body. A turbulence vane is fixedly connected to one end of the rotating rod located inside the filter body.

[0009] Preferably, the sewage discharge device includes a base fixedly connected to the other side wall of the filter body, a sewage discharge pipe is connected to the base, a sewage discharge valve is provided at the sewage discharge pipe, and a groove is designed on the inner wall of the filter body at the corresponding position.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a lifting device, a turbulence device, and a sewage discharge device are designed to work together. A motor that can be lifted by a hydraulic rod is designed at the filter body. After the motor is lifted, the chemical cleaning agent required for cleaning can be added through the through groove. After the motor and the connecting seat are closed, the output shaft of the motor drives the rotating rod and the turbulence blades to rotate and agitate the chemical reagent poured into the filter body, so that the chemical reagent can fully contact the filter mesh. The waste liquid generated can be discharged through the corresponding sewage discharge pipe. The designed groove allows the waste liquid to flow out in a concentrated manner. The corresponding sealing gaskets and sealing rings can be removed to avoid affecting the cleaning process. The overall design is reasonable and convenient for operators to use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A gas pipeline easy-to-clean wire mesh filter includes a filter body 1. Valves 6 are installed at both ends of the filter body 1. The valves 6 are butterfly valves, facilitating quick opening and closing and improving operational efficiency. A filter mesh made of stainless steel is installed on the inner wall of the filter body 1, providing high strength and corrosion resistance, effectively intercepting solid particles in the gas. A connecting seat 5 is fixedly connected to the upper end of the filter body 1 by welding, ensuring a secure connection and preventing gas leakage. A motor 4 is installed on the side of the connecting seat 5. The motor 4 is a high-power brushless motor, providing smooth operation and low noise, suitable for long-term work. The motor 4 is connected to the side wall of the filter body 1 via a lifting device. The lifting device includes two hydraulic rods 2 fixedly connected to the side wall of the filter body 1. The hydraulic rods 2 are filled with hydraulic oil and are operated by an external control system to ensure stability during the lifting process. A connecting frame 3 made of aluminum alloy is fixedly connected to the extended ends of the two hydraulic rods 2, providing lightweight and durable characteristics and reducing overall weight. The connecting bracket 3 is fixedly connected to the side wall of the motor 4. Through the connecting bracket 3, the motor 4 can be securely connected to the filter body 1, ensuring the stability of the motor during operation.

[0020] A flow-deflecting device is fixedly connected to the end of the output shaft of motor 4. This device includes a rotating rod 11 fixedly connected to the end of the motor 4's output shaft. The length and diameter of the rotating rod 11 are precisely calculated to ensure it will not bend or break during high-speed rotation. A connecting seat 5 at the corresponding position has a through-groove. The edges of the through-groove are polished to ensure the output shaft of motor 4 can be smoothly inserted, reducing friction. Through-grooves are provided at the bottom of the through-groove and on the side wall of the filter body 1. The dimensions of these through-grooves match the output shaft of motor 4, ensuring the output shaft can pass through accurately and remain stable. The output shaft of motor 4 passes through both through-grooves, allowing the rotating rod 11 to extend into the filter body 1. When motor 4 starts, the rotating rod 11 rotates, driving the flow-deflecting vanes 12 to work and promote gas flow. A flow-deflecting vane 12 is fixedly connected to one end of the rotating rod 11 inside the filter body 1.

[0021] Specifically, a drain device is fixedly connected to the other side wall of the filter body 1 at the corresponding position. The drain device includes a base 7 fixedly connected to the other side wall of the filter body 1. The base 7 is made of high-strength cast iron and has the characteristics of strong load-bearing capacity and wear resistance. A drain pipe 8 is connected to the base 7, and a drain valve is installed at the drain pipe 8. A groove is designed on the inner wall of the filter body 1 at the corresponding position to allow waste liquid to flow out in a concentrated manner.

[0022] Specifically, a sealing gasket 9 is provided between the side wall of the motor 4 and the groove wall. The sealing gasket 9 is made of high-temperature resistant silicone material, which can maintain a good sealing effect under high temperature and high pressure environment and prevent gas leakage. A sealing ring 10 is provided between the side wall of the output shaft of the motor 4 and the inner wall of the through groove. The sealing ring 10 adopts a double-layer design to further enhance the sealing performance and ensure that the output shaft of the motor 4 will not leak air when rotating. A snap-fit ​​groove is provided through the side wall of the sealing ring 10, which allows the operator to easily pry out the sealing ring 10.

[0023] In this invention, when the operator needs to clean the filter mesh and inner wall inside the filter body 1, the hydraulic rod 2 can drive the connecting frame 3 and the motor 4 to move synchronously, allowing one end of the motor 4 to disengage from the groove, pull out the sealing gasket 9 in the groove, and pry out the sealing ring 10 at the through groove. Then, the chemical cleaning agent to be used for cleaning can be added into the filter body 1 through the through groove (the choice of cleaning agent depends on the type of impurities; for example, if it is oily impurities, an alkaline cleaning agent can be used; if it is acidic dirt, an acidic cleaning agent can be used). After filling, the hydraulic rod 2 can be used to return the motor 4 to its original position. Then, the relevant controller in the prior art controls the motor 4 to drive the rotating rod 11 and the turbulence vane 12 to rotate synchronously, stirring the filled liquid and allowing the inner wall of the filter body 1 and the filter mesh to fully contact the chemical cleaning agent. The waste liquid generated during cleaning will be concentrated on the lower side of the filter body 1 due to the groove. It can be discharged after opening the drain valve on the corresponding drain pipe 8, which is convenient for cleaning.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
