Description

Technical Field

[0001] The invention belongs to the technical field of adsorption cylinders, and in particular relates to an adsorption cylinder for producing nitrogen. Background Art

[0002] Nitrogen is usually a colorless and odorless gas, and its density is generally lower than that of air. Due to its inactive chemical properties, it is difficult to react with other substances at room temperature, so it is often used to make preservatives. However, under high temperature and high energy conditions, it can undergo chemical changes with certain substances to produce new substances useful to humans. In the production of nitrogen, an adsorption cylinder is used, which is referred to as a nitrogen adsorption cylinder. The existing adsorption cylinders have various functions and can realize the regeneration of adsorbed molecules.

[0003] For example, patent application No. CN202321139309.X discloses an adsorption cylinder of a nitrogen generator, comprising an adsorption cylinder, a regeneration mechanism, an installation mechanism, a fan, an air outlet pipe and a carbon molecular sieve cylinder, wherein the regeneration mechanism is fixedly connected to the lower right end of the adsorption cylinder, the installation mechanism is detachably connected to the left end of the adsorption cylinder, the fan is fixedly connected to the bottom of the adsorption cylinder, and a regeneration mechanism is provided. First, the partial pressure of the gas in the carbon molecular sieve cylinder is reduced by a second air pump, and then the inert gas is heated by a heating element to regenerate the carbon molecular sieve, thereby reducing the time, energy and cost of frequent replacement of the carbon molecular sieve. An installation mechanism is provided to drive four groups of movable plates to make relative motion through a cylinder, thereby separating the carbon molecular sieve cylinder from the four groups of movable plates, so as to replace the carbon molecular sieve cylinder, thereby preventing the carbon molecular sieve from being regenerated for a long time and causing the adsorption effect to be reduced, thereby affecting nitrogen production.

[0004] The prior art realizes the regeneration of carbon molecular sieves and improves the replacement efficiency, making maintenance easier, but there are still certain shortcomings: the nitrogen adsorption cylinder is one of the supporting components of the nitrogen production equipment. During installation, it needs to be moved to a suitable installation position and connected to other pipelines. During daily use, it also needs to be disassembled regularly to facilitate inspection and maintenance. Due to the large size of the adsorption cylinder, a lifting device is required to lift and transfer the cylinder during its installation and daily maintenance operations, which makes it inconvenient to move. The prior art lacks equipment that can provide a stable support and movement. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides an adsorption cylinder for nitrogen production. The present invention arranges a sealing arc plate, an arc-shaped ring plate, an elastic ring cloth, a shock-absorbing tube, etc., so that the adsorption cylinder can be effectively clamped, supported, and fixed. Good shock resistance can be guaranteed during movement and fixation, and the adsorption cylinder can be prevented from shaking and being damaged. The arrangement of the elastic bellows and the fixing rod can ensure that the adsorption cylinder can be stably supported when the equipment is short-circuited and powered off, thereby ensuring safety during use.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adsorption cylinder for nitrogen production, comprising a support seat and a drive seat, wherein a plurality of drive seats are arranged below the support seat, a plurality of crawling wheels are evenly arranged in the linear direction in the drive seat, a bending ring plate is slidably arranged above the support seat, an adsorption cylinder is placed on the bending surface of the bending ring plate, an annular tube is arranged on the outer circumferential surface of the adsorption cylinder, a plurality of annular plates are evenly slidably arranged in the annular tube along the circumferential direction, a plurality of hard strips are arranged on both sides of the inner circumferential surface of each annular plate, a sealing arc plate made of elastic metal wire and bent outward is connected between the plurality of hard strips, a plurality of elastic bellows are evenly connected between the bending ring plate and the support seat along the circumferential direction, a fixing rod is arranged on the end surface of the support seat in each of the elastic bellows, and the fixing rod is made of elastic buffer material.

[0009] Preferably, a plurality of second push cylinders are arranged on the outer circumferential surface of the annular tube, and the output end of each second push cylinder is connected to the annular plate. The arrangement of the second push cylinders enables the annular plate to smoothly clamp and fix the adsorption tube.

[0010] Preferably, arc-shaped ring plates are arranged on the inner surface of the fixing ring at both the upper and lower sides of the annular tube. The arrangement of the arc-shaped ring plates enables the fixing ring to perform basic stabilization on the adsorption tube.

[0012] Preferably, a bell-shaped sleeve is arranged above the pressure rod at the top of the elastic bellows. The arrangement of the sleeve improves the contact efficiency between the elastic bellows and the pressure rod.

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0030] refer to Figure 1-10 A nitrogen adsorption cylinder comprises a support seat 58 and a drive seat 64. A plurality of drive seats 64 are arranged below the support seat 58. A plurality of crawling wheels 66 are evenly arranged in a straight line direction in the drive seat 64. A bending ring plate 61 is slidably arranged above the support seat 58. An adsorption cylinder 56 is placed on the bending surface of the bending ring plate 61. An annular tube 63 is arranged on the outer circumferential surface of the adsorption cylinder 56. A plurality of annular plates 67 are evenly slidably arranged in the annular tube 63 along a circumferential direction. A plurality of hard strips 70 are arranged on both sides of the inner circumferential surface of each annular plate 67. A sealing arc plate 68 made of elastic metal wire and bent outward is connected between the plurality of hard strips 70. A plurality of elastic bellows 60 are evenly connected in a circumferential direction between the bending ring plate 61 and the support seat 58. A fixing rod 75 is arranged on the end surface of the support seat 58 in each elastic bellows 60. The fixing rod 75 is made of elastic buffer material.

[0031] When the adsorption cylinder 56 needs to be inspected at the bottom or used for the purpose of being moved, the staff can place the adsorption cylinder 56 on the bending ring plate 61 when leaving the factory. The bending ring plate 61 has multiple angles, among which the inner bending angle surface can effectively wrap and support the bottom of the adsorption cylinder 56, so that the adsorption cylinder 56 can be placed stably. When the adsorption cylinder 56 is placed, the multiple annular plates 67 will move toward the adsorption cylinder 56, thereby driving the multiple hard pressure strips 70 on the inner circular surface to move to the outside of the adsorption cylinder 56, so that the adsorption cylinder 56 can be rigidly clamped and fixed. In this process, the sealing arc plate 68 will also abut against the outside of the adsorption cylinder 56. The sealing arc plate 68 will be elastically deformed due to the pressure, so that it can flexibly support the outside of the adsorption cylinder 56 and absorb vibration, thereby improving the stability of the adsorption cylinder 56 and enabling the adsorption cylinder 56 to complete efficient adsorption processing at any time.

[0032] When the equipment needs to move, multiple crawling wheels 66 will contact the ground and crawl on the ground, thereby driving the driving seat 64 and the supporting seat 58 to move, thereby driving the adsorption cylinder 56 to move. When the adsorption cylinder 56 needs to be lifted upward, the bending ring plate 61 can move upward under the action of external objects, thereby lifting the adsorption cylinder 56.

[0033] When the bending ring plate 61 is lifted up and down, the bending ring plate 61 will drive one end of the top of the elastic bellows 60 to move up and down, causing the elastic bellows 60 to elastically deform. At this time, if the equipment is powered off and short-circuited, the bending ring plate 61 cannot continue to push the support to slide downward, and the top of the elastic bellows 60 will move downward due to the movement of the bending ring plate 61. At this time, the top of the bending ring plate 61 will contact the top of the fixing rod 75. The fixing rod 75 can absorb the vibration generated when the bending ring plate 61 falls, thereby ensuring that the adsorption cylinder 56 will not shake at will and providing certain support to the support plate 65, so that the adsorption cylinder 56 will not be damaged.

[0034] refer to Figure 1-2 , 4, 8, a plurality of first push cylinders 59 are evenly arranged on the end surface of the support seat 58 along the circumferential direction, and the output end of each first push cylinder 59 is connected to the bending ring plate 61.

[0035] The output end of the first push cylinder 59 can push the bending ring plate 61 to move up and down, thereby pushing the adsorption cylinder 56 to move up and down at will.

[0036] refer to Figure 7 A telescopic tube 76 is provided at the top of each fixed rod 75, and a pressure rod 78 is slidably provided in the telescopic tube 76. One end of the top of the pressure rod 78 extends out of the end surface of the fixed rod 75, and a first spring 77 is connected between the pressure rod 78 and the bottom of the telescopic tube 76.

[0037] The setting of the first spring 77 ensures that when the bending ring plate 61 slides downward quickly, the top of the elastic bellows 60 will first contact the top of the pressure rod 78, causing the pressure rod 78 to slide downward, so that the first spring 77 is forced to absorb a certain vibration, and then the fixed rod 75 absorbs the vibration and provides support, which can effectively improve the vibration absorption rate and ensure the stability of the adsorption cylinder 56.

[0038] refer to Figure 4 An elastic ring cloth 71 is arranged on the inner curved surface of the bending ring plate 61 , and a plurality of hard pad rings 72 are arranged on one side of the elastic ring cloth 71 on the end surface of the bending ring plate 61 .

[0039] When the adsorption cylinder 56 is placed in the bent ring plate 61, the top of the hard pad ring 72 will contact the adsorption cylinder 56, thereby providing rigid support for the adsorption cylinder 56, and the elastic ring cloth 71 will contact the bent surface at the bottom of the adsorption cylinder 56 and be deformed under pressure. The elastic ring cloth 71 is made of elastic shock-absorbing material and can be deformed under pressure, so that the vibration transmitted to the adsorption cylinder 56 can be absorbed, thereby improving stability.

[0040] refer to Figure 4 , 10 A plurality of second push cylinders 62 are arranged on the outer circumferential surface of the annular tube 63 , and the output end of each second push cylinder 62 is connected to the annular plate 67 .

[0041] The output end of the second push cylinder 62 can push the annular plate 67 to move, so that the adsorption cylinder 56 can be clamped and fixed smoothly.

[0042] refer to Figure 4 Arc-shaped ring plates 69 are provided on the inner circumferential surface of the fixing ring 57 on both the upper and lower sides of the annular tube 63 .

[0043] The arc-shaped ring plate 69 can perform basic sealing on the adsorption cylinder 56, so that the adsorption cylinder 56 will not shake randomly when there is no clamping force.

[0044] refer to Figure 8 A plurality of shock absorbing tubes 80 are arranged at the bottom of the support seat 58, and a telescopic rod 81 is slidably arranged in each shock absorbing tube 80. One end of the bottom of the telescopic rod 81 is connected to the driving seat 64, and a second spring 82 is connected between the top of the telescopic rod 81 and the shock absorbing tube 80.

[0045] The arrangement of the telescopic rod 81 enables the driving seat 64 and the crawling wheel 66 to swing up and down when the ground is convex or concave, and the second spring 82 can absorb the vibration to prevent the entire device from shaking a lot during movement.

[0046] refer to Figure 5 A third push cylinder 73 is arranged on the bottom end surface of the support seat 58, and a support plate 65 is connected to the bottom output end of the third push cylinder 73.

[0047] When the device stops moving, the output end of the third pushing cylinder 73 can push the supporting plate 65 to move downward and contact the ground, thereby effectively reinforcing the entire device. Embodiment 2:

[0048] On the basis of or different from the first embodiment, reference Figure 6 A plurality of damping plates 74 are connected between the sealing arc plate 68 and the annular plate 67 .

[0049] The provision of the shock-absorbing plate 74 increases the elastic supporting pressure of the sealing arc plate 68 on the adsorption cylinder 56, thereby ensuring the effect of absorbing vibrations. Embodiment three:

[0050] On the basis of or different from the first embodiment, reference Figure 7 A bell-shaped sleeve 79 is provided above the pressure rod 78 and at the top of the elastic bellows 60 .

[0051] The arrangement of the sleeve 79 enables the sleeve 79 to better cover and press the top of the pressure rod 78 when the top of the elastic bellows 60 is pressed downward, thereby ensuring that the pressure rod 78 and the fixing rod 75 are fully compressed, thereby improving the supporting and shock absorbing effects.

[0052] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0053] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
