An environmental test chamber air filter

Abstract

This utility model discloses an air filter for an environmental test chamber, relating to the field of air filter technology. It includes a chamber and a filter. A filtration mechanism is located on the side of the filter away from the chamber, and a push-pull door is located at the bottom of the filter. This environmental test chamber air filter allows a rotating rod to move a circular rod downwards, causing a cleaning plate and a pushing rod to move downwards simultaneously. As the cleaning plate moves downwards, it cleans the side surface of the filter plate, reducing residual impurities. The downward movement of the pushing rod aligns it with the filter holes, facilitating subsequent operations. Further rotation of the rotating rod moves the circular rod to the left, allowing the pushing rod to enter the filter holes and clean impurities within them. These impurities are then discharged through the holes on the left side, resulting in a comprehensive cleaning of the filter plate. This reduces manual operation and is convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to an air filter for an environmental test chamber. Background Technology

[0002] An air filter is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It delivers purified air with low dust content into the room to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms.

[0003] According to patent application number CN202021128865.3, this utility model provides an environmental testing chamber. This utility model simulates an indoor environment through a sealed chamber, exposing the sample inside for a certain period of time, and then collecting harmful gases inside the chamber. This avoids the problem of inaccurate test results when directly sampling gases with slow volatilization rates. At the same time, the sample volatilizes naturally inside the sealed chamber, eliminating the need for operators to wait for a long time and avoiding prolonged exposure to harmful environments, thus eliminating safety hazards. In addition, based on existing air samplers, a lifting device is added to adjust the working height of the air sampler, which facilitates sampling operations. When filtering gases through an air filter, impurities may remain on the sides of the filter plate and in the filter holes. During cleaning, it is impossible to clean the side surfaces and filter holes sequentially, causing problems with the adaptability of the air filter and ease of use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air filter for an environmental test chamber. The rotation of a rotating rod causes a circular rod to move downwards, simultaneously moving a cleaning plate and a pushing rod downwards. As the cleaning plate moves downwards, it cleans the side surface of the filter plate, reducing residual impurities. The downward movement of the pushing rod aligns it with the filter holes, facilitating subsequent operations. Further rotation of the rotating rod moves the circular rod to the left, allowing the pushing rod to enter the filter holes and clean impurities within them. These impurities are then discharged through the holes on the left side. This allows for sequential cleaning of the side surface and filter holes, providing a comprehensive cleaning of the filter plate while reducing manual operation. It is convenient to use and solves the problem of impurities remaining on the sides and in the filter holes, hindering the sequential cleaning of the side surface and filter holes, thus compromising the air filter's adaptability and ease of use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an air filter for an environmental test chamber, comprising a chamber body and a filter, wherein a filtration mechanism is provided on the side of the filter away from the chamber body, and a push-pull door panel is provided at the bottom of the filter.

[0013] Preferably, the top and bottom ends of the sliding rod are fixedly connected to the corresponding fixed rods, and the inner wall of the cleaning plate is in contact with the filter plate.

[0014] Beneficial effects This invention provides an air filter for an environmental test chamber. Compared with the prior art, it has the following advantages: 1. The air filter in this environmental test chamber uses a rotating rod to move a circular rod downwards, causing the cleaning plate and the push rod to move downwards simultaneously. As the cleaning plate moves downwards, it cleans the side surface of the filter plate, reducing residual impurities. The downward movement of the push rod aligns it with the filter holes, facilitating subsequent operations. Further rotation of the rotating rod moves the circular rod to the left, allowing the push rod to enter the filter holes and clean impurities within them. These impurities are then discharged through the holes on the left side. This process cleans both the side surface and the filter holes sequentially, providing a comprehensive cleaning of the filter plate while reducing manual operation and making it convenient to use.

[0015] 2. The air filter of this environmental test chamber moves downward through the blockage plate, causing the blockage plate to separate from the outlet. At the same time, the round rod fixedly connected to the blockage plate moves downward, which can discharge the cleaned impurities through the outlet to prevent them from remaining in the air inlet.

[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. 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: an air filter for an environmental test chamber, including a chamber body 1 and a filter 3. A filter mechanism 2 is provided on the side of the filter 3 away from the chamber body 1, and a push-pull door panel 4 is provided at the bottom of the filter 3.

[0020] The filtration mechanism 2 includes an air inlet 201, a filter plate 202 is provided inside the air inlet 201, and filter holes 203 are provided on the surface of the filter plate 202. A cleaning plate 204 is provided on the top of the air inlet 201, and the cross-sectional shape of the cleaning plate 204 is U-shaped. The cleaning plate 204 is in contact with the air inlet 201, and holes 205 are provided on the surface of the cleaning plate 204. A crossbar 206 is fixedly provided on one side of the cleaning plate 204, and a push rod 207 is provided at the bottom of the crossbar 206. There are multiple push rods 207. A fixing rod 208 is fixedly provided at the bottom of the end of the push rod 207 away from the cleaning plate 204. The crossbar 206 is fixedly connected to the push rod 207 through the fixing rod 208. A rotating rod 209 is provided at the bottom of the air inlet 201, and a round rod 210 is provided at the end of the rotating rod 209 away from the chamber 1.

[0021] An outlet 211 is provided on the bottom surface of the air inlet 201. A block plate 212 is provided inside the outlet 211 and is fixedly connected to the air inlet 201 by screws. The block plate 212 is in contact with the filter plate 202 and is fixedly connected to the round rod 210. A moving plate 213 is provided on one side of the bottom end of the round rod 210. When the screws are removed, the block plate 212 can be moved downward, so that the block plate 212 is separated from the outlet 211. At the same time, the round rod 210 fixedly connected to the block plate 212 moves downward, so that the cleaned impurities can be discharged through the outlet 211 to prevent them from remaining in the air inlet 201.

[0022] A bracket 214 is provided at the bottom of the air intake end 201. The bracket 214 is rotatably connected to one end of the rotating rod 209. Because the cross-sectional shape of the bracket 214 is L-shaped, the bracket 214 can prevent the rotating rod 209 from falling and allow the rotating rod 209 to rotate around the bracket 214.

[0023] The areas of the filter holes 203 and the holes 205 are equal. One end of the push rod 207 is adapted to the filter holes 203 and the holes 205 respectively, so that the push rod 207 can enter the filter holes 203 to clean the impurities in the filter holes 203 and push the impurities into the holes 205 on the left side for discharge.

[0024] Please see Figure 2-4There are multiple horizontal bars 206, which are arranged vertically and collinearly. A sliding rod 215 is provided between each pair of adjacent horizontal bars 206. A rectangular groove 216 is provided at the bottom end of the sliding rod 215, and the bottom end of the sliding rod 215 passes through the rectangular groove 216. The top and bottom ends of the sliding rod 215 are fixedly connected to the corresponding fixed rods 208. The inner wall of the cleaning plate 204 is in contact with the filter plate 202. When the lower fixed rod 208 moves, because each pair of adjacent upper and lower fixed rods 208 is fixedly connected by the sliding rod 215, all the sliding rods 215 can move together, which improves the efficiency of the work. The sliding rods 215 can move along the rectangular groove 216, and the push rods 207 on one side of the sliding rod 215 move at the same time, so that all the push rods 207 move together, which can then clean all the filter holes 203.

[0025] During operation, the sample can be introduced into the chamber 1 via the sliding door 4, and then closed. When external gas enters the filter 3 through the inlet 201, it first comes into contact with the filter plate 202 in the inlet 201. Filtering occurs through the filter holes 203 on the surface of the filter plate 202, and the gas continues to flow into the chamber 1, ensuring its cleanliness. When cleaning the filter plate 202 is required, the screws under the plug plate 212 are removed. After removal, the bracket 214 is rotatably connected to one end of the rotating rod 209, allowing... The rotating rod 209 rotates around the bracket 214. As the rotating rod 209 rotates, it comes into contact with the moving plate 213. The rotation of the rotating rod 209 pushes the moving plate 213 downwards. When the rotating rod 209 rotates 90 degrees, it prevents the moving plate 213 from continuing to move downwards. The downward movement of the moving plate 213 causes the round rod 210 to move downwards as well. The blocking plate 212 and a fixed rod 208, which are fixedly connected to the round rod 210, also move downwards. The downward movement of the blocking plate 212 separates it from the outlet 211, facilitating subsequent operations. When the fixed rod 208 moves downwards, because... The two adjacent fixed rods 208 are connected to the sliding rods 215. Moving the fixed rods 208 causes all the sliding rods 215 to move, and consequently, the crossbar 206 and the push rod 207 move together. The movement of the crossbar 206 causes the cleaning plate 204 to move downwards. Because the inner wall of the cleaning plate 204 contacts the filter plate 202, the movement of the cleaning plate 204 allows it to contact both sides of the filter plate 202. The downward movement of the cleaning plate 204 cleans the side surface of the filter plate 202, reducing impurities remaining on it. When the cleaning rod is no longer moving downwards, the holes 205 on the surface of the cleaning rod and the push rod 207 are in contact with the filter holes 202. After alignment, the rotating rod 209 gradually separates from the moving plate 213 and comes into contact with the round rod 210 by continuing to rotate. The rotation of the rotating rod 209 causes the round rod 210 to move, which in turn pushes the upper push rod 207 and the fixed rod 208 to move. This allows the sliding rod 215 to move along the rectangular groove 216. The movement of the sliding rod 215 also moves all the push rods 207, pushing them into the filter holes 203 to clean the filter holes 203 and allow impurities to be discharged through the holes 205 on the left side. This allows for a thorough cleaning of the filter plate 202, reduces manual operation, and is convenient to use.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
