Description

Technical Field

[0001] This utility model relates to the field of acid corrosion detection technology, and in particular to an acid corrosion detection component. Background Technology

[0002] Acid mist may remain in the system to be evacuated. If it enters the vacuum equipment through the pipeline, it will eventually damage the vacuum equipment. In order to analyze whether the damage to the vacuum equipment is caused by acid mist corrosion, a detection structure is set at the inlet of the vacuum equipment. The internal guide tube is equipped with an acid detection reagent connected to one end of the guide plate. After the device has been running for a certain period of time, the sample removal structure is removed and the acid detection reagent is taken out to see if it has deteriorated, thereby analyzing whether acidic substances have been introduced into the vacuum equipment.

[0003] In a current acid corrosion detection component, the residual acid mist concentration may be extremely low and the flow path may be dispersed in a vacuum environment. Relying solely on the guide tube makes it difficult for the acid mist to fully contact the detection reagent, which can easily lead to the reagent not deteriorating and resulting in a "false negative" result, making it impossible to accurately determine the leakage situation. In addition, in a current acid corrosion detection component, the detection chamber is disassembled and installed using multiple bolts, which is time-consuming, labor-intensive, and impractical. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where, in a vacuum environment, the concentration of residual acid mist may be extremely low and the flow path is dispersed. It is difficult to ensure that the acid mist can fully contact the detection reagent by relying solely on the guide tube, which can easily lead to the reagent not deteriorating and resulting in "false negative" results. It is also difficult to accurately determine the leakage situation. Furthermore, the detection chamber is disassembled and installed using multiple bolts, which is time-consuming and labor-intensive. Therefore, this invention proposes an acid corrosion detection component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an acid corrosion detection component, comprising a housing, with connecting pipes fixed at both ends of the housing, a detection chamber placed inside the housing, and connecting ports at both ends of the detection chamber, a drain pipe fixed on one side of the connecting port on the inner wall of the housing, the drain pipe being connected to one of the connecting pipes, multiple glass fiber filter membranes inserted into the detection chamber, a cover plate placed against the outer side of the detection chamber inside the housing, a first bracket fixed at both ends of the cover plate, and a second bracket matching the first bracket fixed at both ends of the outer wall of the housing, the second bracket on the right side having a clamping and locking structure for installing and removing the cover plate.

[0006] Preferably, the clamping and locking structure includes a motor located at one end of the second right bracket. The output end of the motor passes through one end of the second right bracket and is fixed with a bidirectional screw. Both ends of the outer wall of the bidirectional screw are threaded with moving blocks. The ends of the two moving blocks away from the bidirectional screw are slidably connected to a limit post. The top ends of the two moving blocks are fixed with connecting blocks. The top ends of the two connecting blocks pass through the second right bracket and are fixed with locking blocks. The two locking blocks clamp and engage within the first right bracket.

[0007] Preferably, each of the glass fiber filter membranes has a first handle fixed at its top end above the detection chamber, the first handle penetrating the cover plate and located outside the cover plate.

[0008] Preferably, the bottom end of the first bracket on the right side is provided with a slot that matches the card block, and the top end of the second bracket on the right side is provided with a moving slot that matches the connecting block.

[0009] Preferably, the end of the bidirectional screw away from the motor is rotatably connected to the second bracket on the right, both ends of the limiting post are fixed to the second bracket on the right, one end of the second bracket on the right is fixed with a fixing frame, and the motor is installed on the end of the fixing frame facing the second bracket on the right.

[0010] Preferably, a limiting block is fixed at the bottom of the first bracket on the left, a limiting groove matching the limiting block is opened at the top of the second bracket on the left, a second handle is fixed on both sides of the top of the cover plate, a handle groove is opened on both sides of the top of the detection chamber, and a flange is fixed on the outer wall of the opposite ends of the two connecting pipes.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, multiple glass fiber filter membranes are installed inside the original detection chamber. These membranes can pre-capture and concentrate trace amounts of acid mist flowing through the chamber through adsorption. The lower half of the glass fiber filter membrane is located within the detection chamber and comes into contact with the acidic detection reagent, thus allowing the concentrated acid mist to contact the reagent and improving detection efficiency. Furthermore, when disassembling the detection chamber, simply drive the motor to rotate the bidirectional screw, causing two moving blocks to move in opposite directions under the limit of the limiting post. This causes the two locking blocks connected to the two connecting blocks to move in opposite directions, disengaging them from the two slots at the bottom of the first support on the right side. The user can then directly lift the cover plate and remove the entire detection chamber using the handle slot, making disassembly more convenient. Moreover, when the cover plate is removed, it no longer limits the glass fiber filter membrane, allowing the user to remove it using the first handle for replacement, enhancing its practicality.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, as Figure 1-4 As shown, this utility model provides an acid corrosion detection component, including a housing 1, with connecting pipes 2 fixed at both ends of the housing 1, a detection chamber 20 placed inside the housing 1, and connecting ports 10 opened at both ends of the detection chamber 20. A drain pipe 4 is fixed on one side of the connecting port 10 on the inner wall of the housing 1, and the drain pipe 4 is connected to one of the connecting pipes 2. Multiple glass fiber filter membranes 5 are inserted into the detection chamber 20. A cover plate 7 is placed against the outside of the detection chamber 20 inside the housing 1. First brackets 11 are fixed at both ends of the cover plate 7. Second brackets 12 matching the first brackets 11 are fixed at both ends of the outer wall of the housing 1. A clamping and locking structure 15 for installing and removing the cover plate 7 is provided in the second bracket 12 on the right side.

[0017] The overall effect of embodiment 1 is that the gas enters the housing 1 through one of the connecting pipes 2 and then exits through the other connecting pipe 2. When the gas enters the housing 1, it is guided by the drainage pipe 4 and enters from the connecting port 10 at one end of the detection chamber 20, directly contacting the acidic detection reagent in the detection chamber 20. Through the setting of the glass fiber filter membrane 5, the trace amount of acid mist flowing through it is pre-captured and concentrated by adsorption. The glass fiber filter membrane 5 is set in the detection chamber 20, and its lower half will contact the acidic detection reagent in the detection chamber 20, so that the concentrated acid mist comes into contact with the acidic detection reagent, resulting in better detection effect. Through the setting of the clamping and locking structure 15, the cover plate 7 can be quickly installed and removed, thereby allowing for quick installation and removal of the detection chamber 20 with the cover plate 7 pressed in.

[0018] Example 2, as Figure 1-4 As shown, the clamping and locking structure 15 includes a motor 1501 located at one end of the second right bracket 12. The output end of the motor 1501 passes through one end of the second right bracket 12 and is fixed with a bidirectional screw 1502. Both ends of the outer wall of the bidirectional screw 1502 are threadedly connected to moving blocks 1503. The ends of the two moving blocks 1503 away from the bidirectional screw 1502 are slidably connected to a limit post 1504. The tops of the two moving blocks 1503 are fixed with connecting blocks 1505. The tops of the two connecting blocks 1505 pass through the second right bracket 12 and are fixed with locking blocks 1506. The two locking blocks 1506 clamp and engage inside the first right bracket 11. The top of each glass fiber filter membrane 5 located above the detection chamber 20 is fixed with a first handle 6. The first handle 6 passes through the cover plate 7 and is located outside the cover plate 7. The bottom of the frame 11 is provided with a slot 17 that matches the card block 1506. The top of the second support 12 on the right is provided with a moving slot 19 that matches the connecting block 1505. The end of the bidirectional screw 1502 away from the motor 1501 is rotatably connected to the second support 12 on the right. The two ends of the limiting post 1504 are fixed to the second support 12 on the right. One end of the second support 12 on the right is fixed with a fixing frame 18. The motor 1501 is installed on the end of the fixing frame 18 facing the second support 12 on the right. The bottom of the first support 11 on the left is fixed with a limiting block 13. The top of the second support 12 on the left is provided with a limiting slot 14 that matches the limiting block 13. The top of the cover plate 7 is fixed with a second handle 8 on both sides. The top of the detection chamber 20 is provided with a handle slot 9 on both sides. The outer walls of the opposite ends of the two connecting pipes 2 are fixed with flanges 3.

[0019] The overall effect of Embodiment 2 is that when disassembling the detection chamber 20, the device only needs to drive the motor 1501 to run, which drives the bidirectional screw 1502 to rotate, causing the two moving blocks 1503 to move in opposite directions under the limit of the limiting post 1504. This causes the two locking blocks 1506 connected by the two connecting blocks 1505 to move in opposite directions, so that the two locking blocks 1506 disengage from the two locking slots 17 opened at the bottom of the right first bracket 11. At this time, the user can directly lift up and remove the cover plate 7, and then directly remove the entire detection chamber 20 through the handle slot 9. Disassembly is more convenient, and when the cover plate 7 is removed, the cover plate 7... The glass fiber filter membrane 5 is no longer limited, and the user can remove the glass fiber filter membrane 5 through the first handle 6 for replacement, which is more practical. During installation, the detection chamber 20 is first placed into the box 1. Guided by the first handle 6, the cover plate 7 is engaged. At this time, it is only necessary to drive the two locking blocks 1506 to move towards each other, so that the first bracket 11 and the second bracket 12 on the right side can be engaged and locked. Then, through the cooperation of the limiting block 13 and the limiting groove 14, the first bracket 11 and the second bracket 12 on the left side can be limited. The flange 3 facilitates the connection of the connecting pipe 2 to the external mechanism.

[0020] Working Principle: When in use, gas enters the housing 1 through one connecting pipe 2 and exits through the other connecting pipe 2. Upon entering the housing 1, the gas is guided by the drainage pipe 4 and enters through the connecting port 10 at one end of the detection chamber 20, directly contacting the acidic detection reagent inside. The glass fiber filter membrane 5, through adsorption, pre-captures and concentrates the trace amounts of acid mist flowing through it. The lower half of the glass fiber filter membrane 5, located inside the detection chamber 20, contacts the acidic detection reagent, thus ensuring better contact between the concentrated acid mist and the reagent, resulting in improved detection performance. Furthermore, when disassembling the detection chamber 20, simply drive the motor 1501, which rotates the bidirectional screw 1502, causing the two moving blocks 1503 to move in opposite directions under the limit of the limiting post 1504, thereby driving the two connecting blocks 1505 connected to the two... The locking blocks 1506 move in opposite directions, causing the two locking blocks 1506 to disengage from the two locking slots 17 at the bottom of the first bracket 11 on the right side. At this time, the user can directly lift up and remove the cover plate 7, and then directly remove the entire detection chamber 20 through the handle slot 9. Disassembly is more convenient. When the cover plate 7 is removed, the cover plate 7 no longer limits the glass fiber filter membrane 5. The user can remove the glass fiber filter membrane 5 through the first handle 6 and replace it. It is more practical. During installation, the detection chamber 20 is first placed in the box 1. The cover plate 7 is locked by the guide of the first handle 6. At this time, it is only necessary to drive the two locking blocks 1506 to move towards each other, so that the first bracket 11 and the second bracket 12 on the right side can be locked. Then, through the cooperation of the limiting block 13 and the limiting slot 14, the first bracket 11 and the second bracket 12 on the left side can be limited. The flange 3 facilitates the connection of the connecting pipe 2 to the external mechanism.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
