Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen leakage detection, in particular to a nitrogen leakage rapid detection device for a nitrogen generator. Background Art

[0002] Pressure swing adsorption nitrogen generator (PSA nitrogen generator for short) is a nitrogen generating equipment designed and manufactured according to pressure swing adsorption technology. It uses air as raw material and high-quality carbon molecular sieve as adsorbent. It uses the principle of pressure swing adsorption (PSA) and molecular sieves full of micropores to selectively adsorb air to achieve the purpose of oxygen and nitrogen separation.

[0003] At present, nitrogen is generally prepared by a nitrogen generator. The nitrogen generator achieves the purpose of oxygen and nitrogen separation by selectively adsorbing air. The nitrogen generator is usually operated by multiple devices in coordination, and multiple pipelines are connected between the devices. Therefore, in the case of long-term use, the sealing between the pipeline and the equipment will inevitably decrease, resulting in nitrogen leakage. In addition, since nitrogen is a colorless and odorless gas, it is usually not easy to detect when a leakage accident occurs. Therefore, it is necessary to arrange a detection device to detect the nitrogen generator. At present, most of the traditional detection devices are measuring instruments, which judge whether the nitrogen leakage occurs by the change of the instrument reading. However, the instrument reading is not convenient for directly observing whether the nitrogen leakage occurs, and it is not convenient for quickly judging the nitrogen leakage. In view of this, we propose a nitrogen leakage rapid detection device for a nitrogen generator. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art, meet the actual needs, and provide a nitrogen leakage rapid detection device for a nitrogen generator to solve the technical problem that the current instrument reading is not convenient for directly observing whether nitrogen leakage occurs and is not convenient for rapid judgment of nitrogen leakage.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a nitrogen leakage rapid detection device for a nitrogen generator, including a nitrogen generator component with a cover structure sealed and fixed on the top;

[0006] A support component is symmetrically and detachably provided on the top of one side of the cover structure, and a detection component is detachably mounted on the support component;

[0007] The detection component includes a water tank which is hollow inside and stores liquid water. A transmission component for transmitting leaked gas is detachably installed between the top of the cover structure and the water tank. The top of the cover structure and the top of the water tank are both formed with mounting holes for installing and sealing the transmission component.

[0008] Preferably, the transmission component is detachably mounted on a sealing structure in the mounting hole and a transmission pipe having one end extending into the liquid water inside the water tank.

[0009] Preferably, the sealing structure includes a sealing seat fixedly arranged in the mounting hole, and both ends of the transmission pipe can be removed and pass through the sealing seat, the bottom structure of the inner edge surface of the sealing seat is provided with two conical spring sheets, and the bottom of the inner wall of the sealing seat is fixedly provided with two annular plates, and the top of the two annular plates is fixedly provided with one annular sealing member.

[0010] Preferably, a conical spring sheet 1 is fixedly provided on the outer edge surfaces at both ends of the transmission tube, an annular plate 1 is fixedly provided on the bottom end of the conical spring sheet 1, and an annular seal 2 for hooking with the seal 1 is fixedly provided on the bottom end of the annular plate 1, and the seals 1 and 2 are formed with flat head ends on the outer edge surfaces at the bends, and the edges of the flat head ends are structured to form rounded corners.

[0011] Preferably, the support assembly comprises an L-shaped support frame with two sides respectively abutting against the cover structure and the water tank, and both sides of the lower end surface of the water tank are constructed with positioning blocks that can be positioned and inserted into the L-shaped support frame.

[0012] Preferably, fixing bolts 2 and 1 that can be screwed into the cover structure and the positioning block are equidistantly arranged in the L-shaped support frame, and load-bearing ribs are symmetrically arranged at the inner angle of the L-shaped support frame, and detection instruments are equidistantly and detachably installed on the top of the cover structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up a water storage tank, a cover structure and a transmission component, when the nitrogen generator component leaks during the nitrogen production process, the leaked nitrogen fills the cover structure, thereby increasing the air pressure inside the cover structure. Under the action of pressure, the nitrogen enters the water storage tank through the transmission component, thereby generating bubbles in the liquid water in the water storage tank, which is conducive to directly observing whether the nitrogen is leaking and facilitating a quick judgment of the nitrogen leakage.

[0015] 2. By setting a sealing structure at the connection position between the two ends of the transmission component and the cover structure and the water tank, when installing the transmission pipe, the two ends of the transmission pipe can be inserted into the cover structure and the water tank, at this time, the seal 2 at the end of the annular plate and the seal 1 at the end of the second annular plate are in contact with each other, and under the action of continuous insertion, the flat head end and the rounded corner are used to force them to deviate to both sides respectively, and the conical spring sheet 2 is compressed and elastically deformed. Under the action of continuous insertion, when the seal 1 and the seal 2 are separated, the conical spring sheet 1 and the conical spring sheet 2 respectively apply thrust to the seal 1 and the seal 2. At this time, the transmission pipe is pulled upward, so that the ends of the seal 1 and the seal 2 can be grasped and connected with each other, thereby achieving a stable sealing effect and avoiding nitrogen leakage and affecting the accuracy of detection.

[0026] See also Figure 1 , Figure 3 and Figure 4 The support assembly 5 includes an L-shaped support frame 501 with two sides respectively abutting against the cover structure 2 and the water storage tank 401, and the lower end surface of the water storage tank 401 is provided with positioning blocks 402 that can be positioned and inserted in the L-shaped support frame 501 on both sides, and the L-shaped support frame 501 is equidistantly provided with fixing bolts 2 504 and 1 503 that can be screwed into the cover structure 2 and the positioning block 402, and the L-shaped support frame 501 is symmetrically provided with load-bearing ribs 502 at the inner angle, and the top of the cover structure 2 is equidistantly detachably installed with a detection instrument 3. The utility model solves the technical problem that the current instrument reading is not convenient for directly observing whether nitrogen is leaking and is not convenient for quickly judging nitrogen leakage by setting the water storage tank 401.

[0027] Working principle: When in use, first place the water tank 401 on the support assembly 5, and insert the positioning block 402 into the L-shaped support frame 501, then tighten the fixing bolt 2 504 to fix the cover structure 2, the L-shaped support frame 501 and the water tank 401, then insert the two ends of the transmission pipe 601 into the cover structure 2 and the water tank 401 respectively, and extend the transmission pipe 601 toward one end of the water tank 401 and insert it into the liquid water inside.
