Abstract
Description
Technical Field
[0001] This utility model relates to the field of air supply system technology, and in particular to a device for detecting the failure of the sealing strip of an air supply box. Background Technology
[0002] In air supply systems, the sealing performance of filters directly affects air quality and system energy efficiency, with the sealing strip being a key component for reliable sealing. However, current technology lacks dedicated detection devices for the failure of filter sealing strips in air supply boxes, typically relying on periodic manual inspections to assess the sealing status. This method is not only inefficient but also struggles to accurately detect sealing failures caused by factors such as aging or improper installation. Once the sealing strip fails, air leakage occurs, disrupting the airflow organization of the air supply system, reducing air supply efficiency, and increasing energy consumption. Furthermore, the leaked unpurified air also affects the cleanliness of the air supply environment, leading to higher costs for subsequent maintenance. Therefore, this application provides a device for detecting the failure of the sealing strip of the air supply box to meet the requirements. Utility Model Content
[0003] The purpose of this application is to provide a device for detecting the failure of the sealing strip of the air supply box, which aims to solve the problem that the failure of the sealing strip will cause air leakage, disrupt the airflow organization of the air supply system, reduce air supply efficiency, and increase energy consumption.
[0004] To achieve the above objectives, this application provides the following technical solution: a device for detecting the failure of a sealing strip in an air supply box, comprising a box and a filter, wherein a hole is provided in the middle of the box, a screen is installed on the hole, a placement ring plate is provided on the inner wall of the box, and a filter is press-fitted onto the placement ring plate by a fixing mechanism, and a hole for installing a micro-pressure sensor is provided on the outer wall of the box.
[0005] Preferably, the fixing mechanism includes a positioning rod, a clamping member, a nut, and a pressure member. The positioning rod is provided on the placement ring plate and there are multiple sets of positioning rods. The pressure member has a through hole corresponding to the position of the positioning rod. The clamping member is slidably connected to the positioning rod, and the nut with the limit clamping member is threadedly connected to the positioning rod.
[0006] Preferably, the cross-section of the perforation is T-shaped, and a boss that matches the perforation is provided below the pressure member.
[0007] Preferably, the perforation is provided with a sealing ring that matches the boss of the pressing member.
[0008] Preferably, the detection head of the micro-pressure sensor is located between the placement ring plate and the pressure member, and both the upper and lower end faces of the filter are provided with sealing strips.
[0009] In summary, the technical effects and advantages of this utility model are as follows: This invention utilizes a micro-pressure sensor installed on the housing to monitor pressure changes in the sealed environment at the filter installation location in real time. When the sealing strip fails, the micro-pressure sensor can promptly report the pressure anomaly, solving the problem of the inability to detect seal failure in real time and accurately in existing technologies. This effectively ensures the sealing reliability of the air supply system and prevents a decline in air supply quality due to seal failure.
[0010] This utility model, through the design of a fixing mechanism using a positioning rod, a clamping component, a nut, and a pressure component, not only achieves stable installation and positioning of the filter, but also forms multiple sealing guarantees through the cooperation between the clamping component boss and the perforated inner sealing ring, as well as the cooperation between the outer wall sealing strip of the pressure component and the placement ring plate and the filter, further enhancing the sealing effect and effectively preventing air leakage.

[0014] 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.
[0015] Example: Reference Figure 1-6 The device shown is a failure detection device for the sealing strip of an air supply box, including a box 1, a micro-pressure sensor 7, and a filter 8. The inner wall of the box 1 is provided with a placement ring plate 3, which provides a placement point for the filter 8. Through the design of the sealing strips on the front and back of the filter 8, and in conjunction with the fixing mechanism, a sealed environment can be formed at the installation position of the filter 8. With the hole provided on the box 1, the probe of the micro-pressure sensor 7 extends into this sealed environment, which can detect in real time the sealing condition between the sealing strip of the filter 8 and the fixing mechanism and the placement ring plate 3 when the filter 8 is installed at this position. A hole is provided at the bottom of the box 1, and a screen cover 2 is provided on the hole, which can isolate foreign objects.
[0016] As one embodiment of this example, the fixing mechanism includes: six sets of positioning rods 4 on the placement ring plate 3, which can position the filter 8; the shape of the pressing member 9 is the same as that of the placement ring plate 3; a sealing strip is provided on the outer wall of the pressing member 9; and a through hole 900 adapted to the six sets of positioning rods 4 is provided on the pressing member 9. A clamping member 5 is slidably connected to the positioning rod 4. The bottom surface of the clamping member 5 is provided with a boss, which is adapted to the shape of the through hole 900. A nut 6 is threadedly connected to the positioning rod 4 to limit the clamping member 5, thereby fixing the clamping member 9.
[0017] As one embodiment of this invention, the cross-section of the perforation 900 is T-shaped, and a sealing ring 901 is provided inside the perforation 900. The sealing ring 901 cooperates with the boss of the clamping member 5 to achieve a sealing effect.
[0018] The working principle of this utility model is as follows: Place the filter 8 on the placement ring plate 3, then align the through hole 900 on the pressure piece 9 with the positioning rod 4, then lower the pressure piece 9 so that it presses against the filter 8, then put the clamping pieces 5 one by one onto the positioning rod 4, and then tighten the nuts 6 one by one to limit the clamping pieces 5 (the boss of the clamping piece 5 cooperates with the sealing ring 901 in the through hole 900 to achieve a seal), the clamping pieces 5 press down against the pressure piece 9, the pressure piece 9 cooperates with the placement ring plate 3 to fix the filter 8; Then observe the micro-pressure sensor 7 and determine its current value. When the value changes, it indicates an abnormal sealing environment, which can be repaired, inspected, and the corresponding worn parts replaced.
