Description

Technical Field

[0001] The utility model relates to the technical field of gas separation devices, and particularly relates to a gas separation device for gas detection. Background Art

[0002] Since some gases to be detected are mixtures of multiple gases, it is difficult to detect a single component in the gas mixture, and a gas separation device is needed to separate some interfering gases. The most common and easily doped gas in the gas mixture is water vapor, so the separation device for water vapor has the most market prospects.

[0003] In the existing device for separating gases by using water-absorbing particles, the filter container for containing the water-absorbing particles is mostly fixedly installed in the gas channel inside the separation device, resulting in the water-absorbing particles that cannot be or are inconvenient to be slid and vibrated or tumbling-shifted in other forms. During use, the water-absorbing particles near the center position of the filter container are shielded and hidden for a long time and not fully utilized, and cannot tumble and transfer to the outside to contact with water vapor for normal use, which is not conducive to the full and sufficient utilization of the water-absorbing particles. Summary of the Utility Model

[0004] In view of this, the utility model provides a gas separation device for gas detection to solve the problem that the filter container for containing water-absorbing particles is mostly fixedly installed in the gas channel inside the separation device, resulting in the water-absorbing particles that are not fully utilized and cannot tumble and transfer to the outside to contact with water vapor for normal use, which is not conducive to the full and sufficient utilization of the water-absorbing particles.

[0005] The technical solution proposed by the utility model is: a gas separation device for gas detection, specifically including a separation cylinder and a plug plate; the plug plate is detachably installed on the tail-end opening of the separation cylinder;

[0006] A cage-shaped filter cylinder is slidably installed at the center inside the separation cylinder, and the inside of the cage-shaped filter cylinder is used to contain water-absorbing particles; the cage-shaped filter cylinder is integrally composed of a plug cover at the tail end, a sliding tube at the head end, and a circle of support shafts welded around between the plug cover and the sliding tube. A metal filter screen is covered on the space between the circle of support shafts;

[0007] A partition plate is welded at the head-end part of the internal space of the separation cylinder, and the sliding tube is in through-sliding fit with the partition plate. A retaining ring is welded and sleeved on the tail-end part of the sliding tube. Under normal conditions, the retaining ring abuts against the partition plate;

[0008] A driving short shaft is slidably installed at the center of the plug plate through the top push of a spring. The head end of the driving short shaft is fixedly connected to the plug cover, and the driving short shaft is used to pull and drive the cage-shaped filter cylinder to reciprocate and slide, so as to vibrate and tumble the water-absorbing particles.

[0009] Further,

[0010] A filter screen cover with a suitable shape is slidably inserted into the open end at the tail of the sliding pipe. The filter screen cover is integrally composed of a peripheral support ring, a three-pronged holder welded inside the peripheral support ring, and a draw rod welded at the center of the three-pronged holder. A metal filter screen is covered and arranged in the spaced space between the three-pronged holder and the peripheral support ring.

[0011] Further,

[0012] Vertically opposite hexagonal positioning rods are symmetrically welded to the head end part of the draw rod. Two positioning sleeves are symmetrically and slidably mounted on the two hexagonal positioning rods. An insertion rod arranged in the same direction as the hexagonal positioning rod and a finger push rod perpendicular to the insertion rod are welded on the positioning sleeve.

[0021] A gas separation device for gas detection provided by the present utility model has the following beneficial effects:

[0022] When the present utility model is in use, through the driving short shaft, the cage-shaped filter cartridge can be slid backward, and after the driving short shaft is released, the spring thereon can rebound and push to drive the driving short shaft, the cage-shaped filter cartridge and the retaining ring to slide forward rapidly and reset and impact and contact with the partition plate. Furthermore, by simply repeating the actions of pulling backward and releasing the driving short shaft, the cage-shaped filter cartridge can be driven to reciprocate back and forth and vibrate to vibrate and tumble and displace the water-absorbing particles inside it. Compared with the prior art in which the filtering container containing the water-absorbing particles is set statically and the water-absorbing particles cannot be tumbled or displaced inconveniently, the water-absorbing particles that are located near the center of the filtering container and are shielded and hidden for a long time and not fully utilized during use can be tumbled and transferred to the outside to contact with water vapor and be used normally, which is beneficial to the full and sufficient utilization of the water-absorbing particles.

[0024] In addition, under normal conditions, the end disc is pushed and squeezed by the spring on the driving short shaft and abuts against the plug plate, which can seal the sliding gap between the driving short shaft and the plug plate, preventing the mixed gas entering the separation cylinder from leaking through the sliding gap between the driving short shaft and the plug plate, helping to ensure the sealing performance of the separation cylinder in the normal use state, and enabling the separation device to better take into account the sealing performance on the basis of ensuring the vibration and tumbling displacement of the water-absorbing particles.

[0042] Among them, a cage-shaped filter cartridge 3 is slidably installed at the center inside the separation cylinder 1, and the inside of the cage-shaped filter cartridge 3 is used to contain water-absorbing particles; the cage-shaped filter cartridge 3 is integrally composed of a plug cover 303 at the tail end, a slide tube 302 at the head end, and a circle of support shafts welded around between the plug cover 303 and the slide tube 302. A metal filter screen is covered in the space between the circle of support shafts;

The slide tube 302 is in sliding fit with the partition plate 104 through penetration, and a retaining ring 3021 is welded and sleeved on the tail-end part of the slide tube 302. Under normal conditions, the retaining ring 3021 abuts against the partition plate 104, which can squeeze and seal the penetration gap between the slide tube 302 and the partition plate 104, avoiding the leakage of the mixed gas directly through the penetration gap between the slide tube 302 and the partition plate 104 without water filtration, which helps to ensure the purity of the gas separation and filtration treatment of the device;

The first end of the driving short shaft 2 is fixedly connected to the blocking cover 303. Through the driving short shaft 2, the cage-shaped filter cartridge 3 can be slid backward. After releasing the driving short shaft 2, the spring thereon can rebound and push to drive the driving short shaft 2, the cage-shaped filter cartridge 3 and the retaining ring 3021 to slide forward rapidly and reset and impact and contact the partition plate 104. Therefore, by simply repeating the simple actions of pulling the driving short shaft 2 backward and releasing it, the cage-shaped filter cartridge 3 can be driven to reciprocate back and forth and vibrate, so as to vibrate, roll and displace the water-absorbing particles inside it. Compared with the prior art in which the filtering container containing the water-absorbing particles is set statically and the water-absorbing particles cannot be rolled and displaced or are inconvenient to be rolled and displaced, the water-absorbing particles that are located near the center of the filtering container during use and are shielded and hidden for a long time and not fully utilized can be rolled and transferred to the outside to contact with water vapor for normal use, which is beneficial to the full and sufficient utilization of the water-absorbing particles; under normal conditions, the driving short shaft 2 passes through and is placed outside the rear side of the separation cylinder 1, and the cage-shaped filter cartridge 3 installed inside the separation cylinder 1 can be directly driven to slide and vibrate, so that the rolling and displacement operation of the water-absorbing particles can be directly carried out outside the separation device, saving the trouble of having to disassemble and take out the cage-shaped filter cartridge 3, and the operation and use are convenient and efficient;
