Description

Technical Field

[0001] This utility model relates to the field of pipelines, specifically to a waste gas treatment pipeline that facilitates filter replacement. Background Technology

[0002] In industrial production, waste gas treatment is a crucial step to reduce environmental pollution. Waste gas treatment pipelines are a key component of waste gas treatment systems, their function being to transport waste gas from one treatment unit to another, ultimately achieving compliant emissions.

[0003] In the process of exhaust gas treatment, filter cartridges are commonly used filtration elements to remove impurities such as particulate matter and harmful gases from exhaust gases. However, existing exhaust gas treatment pipelines present many inconveniences in terms of filter cartridge replacement.

[0004] On the one hand, many exhaust gas treatment pipelines have complex filter element installation structures, requiring the disassembly of numerous pipeline components or complex operations for filter element replacement. This not only consumes a significant amount of time and manpower but may also damage the sealing of the pipeline system, affecting the exhaust gas treatment effect. For example, some pipelines require the entire pipeline section to be disassembled to remove the filter element, which is cumbersome and prone to leakage. On the other hand, although some exhaust gas treatment pipelines are designed with structures that facilitate filter element replacement, there are deficiencies in the fixing and sealing of the filter element. The filter element may loosen or swing within the pipeline due to vibrations generated by the flow of exhaust gas, resulting in a poor seal between the filter element and the pipeline. This allows some untreated exhaust gas to bypass the filter element and be directly discharged, reducing the efficiency and quality of exhaust gas treatment. Furthermore, insecurely fixed filter elements may also affect their service life, increasing the frequency and cost of filter element replacement.

[0005] Therefore, developing an exhaust gas treatment pipeline that facilitates filter replacement and ensures stable installation and good sealing of the filter element is of significant practical importance. Utility Model Content

[0006] The purpose of this invention is to provide an exhaust gas treatment pipeline that facilitates filter replacement, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment pipe that facilitates filter replacement, comprising a pipe body, multiple pipe bodies connected end to end to transport waste gas, a reserved opening at the bottom of the pipe body, a filter element frame inserted into the reserved opening, a filter element installed inside the filter element frame, multiple screws fixed at the top of the filter element frame, the screws penetrating the top of the pipe body, and a nut screwed onto the top of the screws, after the filter element frame is pushed into the reserved opening, the filter element is blocked in the pipe body, and the nut cooperates with the screws to suspend the filter element frame in the pipe body.

[0008] Preferably, the inner wall of the tube is fixed with a limiting ring. There are two limiting rings, which are symmetrically distributed about the reserved opening. The filter element frame is located between the two limiting rings, and a rubber pad is fixed on the side of the limiting ring close to the filter element frame. The rubber pad is clamped between the filter element frame and the limiting ring.

[0009] Preferably, a baffle is fixed at one end of the inner ring surface of the filter element frame, and a push-in groove is opened at the other end of the inner ring surface of the filter element frame. A clamping ring is inserted into the push-in groove and is fixed in the push-in groove by screws. The clamping ring and the baffle clamp the filter element.

[0010] Preferably, a rubber pad is fixed to the side of the baffle near the filter element.

[0011] Preferably, the bottom surface of the filter element frame is fixed with a support plate. The support plate has an arc-shaped plate structure. The width of the support plate is greater than the width of the reserved opening. Both ends of the support plate have side grooves on the inner ring surface. Rubber pads are fixed inside the side grooves. The rubber pads are clamped between the support plate and the tube body to produce elastic deformation.

[0012] Preferably, the top end of the tube has a through hole for matching the screw, and a rubber ring fitted on the screw body is fixed inside the through hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes an exhaust gas treatment pipe that facilitates filter replacement. When filter replacement is needed, simply loosen the nut from the top of the screw, use a tool to support the bottom of the filter element holder to prevent it from falling off directly, and then pull the filter element holder out from the bottom of the pipe. This design greatly simplifies the filter replacement process, eliminating the need to disassemble numerous pipe components and saving time and labor costs. The entire filter replacement process is relatively easy and can be completed by a single person, improving work efficiency, and is especially suitable for industrial scenarios requiring frequent filter replacement. Two symmetrically distributed limiting rings fixed to the inner wall of the pipe about the reserved opening can restrain the filter element holder between the two limiting rings after it is pushed into the pipe. The rubber gasket fixed to the side of the limiting rings near the filter element holder not only provides a sealing function to prevent exhaust gas leakage, but also effectively prevents the filter element holder from swinging inside the pipe, ensuring the stability of the filter element during operation.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-7 This utility model provides a technical solution: a waste gas treatment pipeline that facilitates filter replacement, comprising a pipe body 1, multiple pipe bodies 1 connected end to end to transport waste gas. A pre-reserved opening 2 is provided at the bottom of each pipe body 1, and a filter element frame 3 is inserted into the pre-reserved opening 2. A filter element 302 is installed inside the filter element frame 3. Multiple screws 6 are fixed to the top of the filter element frame 3, passing through the top of the pipe body 1, and a nut 601 is screwed onto the top of each screw. After the filter element frame 3 is pushed into the pre-reserved opening 2, the filter element 302 is blocked in the pipe body 1. The nut 601, in conjunction with the screws 6, suspends the filter element frame 3 in the pipe body 1. When the filter element 302 needs to be replaced, simply loosen the nut 601 from the top of the screw 6 and pull the filter element frame 3 out from the bottom of the pipe body 1. It should be noted that when removing the nut 601, the bottom of the filter element frame 3 needs to be supported to prevent the filter element frame 3 from falling off directly.

[0017] In order to limit the movement of the filter element holder 3 pushed into the tube body 1, the following was proposed: A limiting ring 4 is fixed to the inner wall of the tube body 1. There are two limiting rings 4, which are symmetrically distributed about the reserved opening 2. The filter element frame 3 is located between the two limiting rings 4, and a rubber pad 401 is fixed on the side of the limiting ring 4 that is close to the filter element frame 3. The rubber pad 401 is clamped between the filter element frame 3 and the limiting ring 4.

[0018] The specific operation of the limiting ring 4 in limiting the filter element frame 3 is as follows: when the filter element frame 3 extends into the tube body 1 from the bottom of the reserved port 2, the limiting ring 4 is located on both sides of the filter element frame 3. After the filter element frame 3 is completely pushed into the tube body 1, the rubber pad 401 is clamped between the filter element frame 3 and the limiting ring 4, which plays a sealing role, and the limiting ring 4 prevents the filter element frame 3 from swinging inside the tube body 1.

[0019] To make filter element 302 removable within filter element holder 3, the following was proposed: A baffle 301 is fixed at one end of the inner ring surface of the filter element holder 3, and a push-in groove is opened at the other end of the inner ring surface of the filter element holder 3. A clamping ring 303 is inserted into the push-in groove and fixed in the push-in groove by screws 304. The clamping ring 303 and the baffle 301 clamp the filter element 302. A rubber pad 3011 is fixed on the side of the baffle 301 near the filter element 302.

[0020] The specific steps for replacing filter element 302 are as follows: First, loosen screw 304. After screw 304 is removed from the surface of the push-in groove, pull out clamping ring 303 from the push-in groove. Then, pull out filter element 302 from filter element holder 3. Push the new filter element 302 into filter element holder 3 and press it against one side of baffle 301. Then, insert clamping ring 303 into the push-in groove and fix clamping ring 303 in the push-in groove with screw 304. Filter element 302 is clamped and limited by baffle 301 and clamping ring 303.

[0021] To achieve the suspension and installation of the filter element holder 3 within the tube body 1, the following proposed method was proposed: The bottom surface of the filter element holder 3 is fixed with a support plate 305. The support plate 305 has an arc-shaped plate structure. The width of the support plate 305 is greater than the width of the reserved opening 2. Both ends of the support plate 305 have side grooves 3051 on the inner ring surface. Rubber pads 3052 are fixed inside the side grooves 3051. The rubber pads 3052 are clamped between the support plate 305 and the tube body 1 to produce elastic deformation. The top end of the tube body 1 has a through hole 5 for matching screw 6. A rubber ring 501 fitted on the screw 6 is fixed inside the through hole 5.

[0022] The installation and removal process for filter element holder 3 is as follows: When installing the filter element holder 3, simply push the filter element holder 3 into the reserved opening 2. At this time, the screw 6 passes through the through hole 5, and the through hole 5 abuts against the bottom of the tube body 1. Screw the nut 601 onto the top of the screw 6 and tighten it. The rubber ring 501 wraps around the screw 6 in the through hole 5 to prevent leakage from the tube body 1. When disassembling the filter element holder 3, use a tool to support the bottom of the through hole 5, then unscrew and remove the nut 601. Then slowly remove the tool supporting the through hole 5 and slowly pull the filter element holder 3 out of the reserved opening 2.

[0023] Instructions for using the exhaust gas treatment pipeline for easy filter replacement: Prepare suitable tools to support the bottom of the filter element holder when removing the nut, preventing it from falling off directly. Use the tool to loosen nut 601 from the top of screw 6, but do not completely remove the nut at this time. While loosening the nut, use the prepared tool to support the bottom of the filter element holder 3. After completely removing nut 601, use the tool to support the bottom of the perforation 5 at the top of the pipe body 1, and then slowly remove the tool supporting the perforation 5 while slowly pulling the filter element holder 3 out of the reserved opening 2 at the bottom of the pipe body 1. Prepare the new filter element: Ensure that the new filter element 302 is intact and meets the usage requirements. Use the tool to loosen screw 304 on the clamping ring 303, causing screw 304 to disengage from the surface of the push-in groove. Pull the clamping ring 303 out of the push-in groove. Push the new filter element 302 into the filter element holder 3, so that it rests against one side of the baffle 301. Insert the clamping ring 303 into the push-in groove, and then use the screw 304 to fix the clamping ring 303 in the push-in groove. At this time, the filter element 302 is clamped and limited by the baffle 301 and the clamping ring 303. Push the filter element holder 3 with the new filter element into the reserved opening 2 at the bottom of the tube body 1. During the pushing process, make sure that the screw 6 at the top of the filter element holder 3 is aligned with the through hole 5 at the top of the tube body 1. Continue to push the filter element holder 3 in, so that the screw 6 passes through the through hole 5, until the filter element holder 3 is completely pushed into the tube body 1, and the support plate 305 on the bottom surface of the filter element holder 3 abuts against the bottom of the tube body 1. At this time, the rubber pads 3052 at both ends of the support plate 305 are clamped between the support plate 305 and the tube body 1 and produce elastic deformation. Put the nut 601 on the top of the screw 6 and tighten it. During this process, the rubber ring 501 inside the perforation 5 will wrap around the rod of the screw 6 in the perforation 5, which will play a sealing role and prevent the tube 1 from leaking.

[0024] Filter element replacement procedure (without replacing the filter element holder): Use a tool to loosen the screw 304 on the clamping ring 303, causing the screw 304 to disengage from the surface of the push-in groove. Pull the clamping ring 303 out of the push-in groove. Pull the filter element 302 out of the filter element holder 3. Push the new filter element 302 into the filter element holder 3, so that it abuts against one side of the baffle 301. Insert the clamping ring 303 into the push-in groove, and then use the screw 304 to fix the clamping ring 303 in the push-in groove, so that the filter element 302 is clamped and limited by the baffle 301 and the clamping ring 303. After the filter element holder 3 extends into the tube body 1 from the bottom of the reserved port 2, the two limiting rings 4 fixed on the inner wall of the tube body 1, symmetrically distributed about the reserved port 2, are located on both sides of the filter element holder 3. After the filter element holder 3 is fully pushed into the tube body 1, the rubber gasket 401 fixed on the side of the limiting ring 4 near the filter element holder 3 clamps between the filter element holder 3 and the limiting ring 4, providing a seal and preventing the filter element holder 3 from swinging inside the tube body 1. The arc-shaped plate-like support 305 fixed to the bottom surface of the filter element holder 3 is wider than the width of the reserved opening 2, and the side grooves 3051 opened on the inner ring surface at both ends of the support 305 have rubber gaskets 3052 fixed inside. When the filter element holder 3 is installed in the tube body 1, the rubber gaskets 3052 are clamped between the support 305 and the tube body 1 and undergo elastic deformation, further enhancing the sealing effect.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
