Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, and in particular to an adsorption tower pressure tower device. Background Art

[0002] In the production of high-purity gas, the gas is usually separated and purified through an adsorption tower. When the mixed gas passes through the packing layer, the target gas is blocked, while the waste gas passes through and is discharged. In the process of gas production and exhaust gas discharge, the gas will repeatedly pass through the packing layer through the control of pressure. After long-term use, it will gradually be worn and dusted, and tiny particles will begin to fall off. At the same time, the pores inside will gradually increase and increase. This phenomenon will seriously weaken the adsorption capacity of the packing.

[0003] To address this problem, traditional technologies often require manual compaction of the fillers in the adsorption tower on a regular basis. However, this method has many disadvantages. First, manual compaction of fillers requires a lot of physical labor, which is a heavy burden on operators. Secondly, due to the limitations of manual operation, there may be omissions in the compaction work, that is, failure to fully compact all fillers, or failure to perform filler compaction operations within the specified time. This omission will accelerate the dusting process of the filler and further weaken its adsorption capacity. Therefore, we need to find a more efficient and reliable filler compaction method to ensure that the air adsorption tower can continue to perform its filtering function stably. Summary of the invention

[0004] The purpose of the present invention is to provide an adsorption tower pressing device to solve the problem that the filler of the filtration tower in the prior art cannot be compacted regularly or is compacted unevenly.

[0015] (2) When installing or replacing the packing of the pressure tower device, the screw rod can be rotated in the reverse direction first, so that the screw rod moves upward and the pressure ring is close to the fixed sleeve to reserve sufficient installation space, reduce the elastic force of the spring, and facilitate installation; after installation, the screw rod is rotated forward so that the screw rod pushes the pressure base downward, so that the pressure base presses the packing, and at the same time, the pressure ring moves downward to press the spring, so that the spring has a driving force to low-pressure the pressure base, so as to ensure that sufficient pressure is applied to the packing after long-term use.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with specific embodiments:

[0023] The present invention is applied to an adsorption tower for air adsorption, in which the filler adsorbs the gas, and after long-term use, the filler will be powdered and affect the adsorption effect. The tower pressing device of the present invention continuously presses the filler so that the filler is always in a compacted state to ensure the adsorption effect of the filler. Specifically:

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, an adsorption tower pressure tower device includes a fixed sleeve 1 connected to the tower tank of the adsorption tower, one end of the fixed sleeve 1 is arranged inside the tower tank, and the other end is outside. The auxiliary heating inner ring of the fixed sleeve 1 is provided with a thread, and a screw rod 2 is threadedly connected. The upper end of the screw rod 2 is provided with a hexagonal head 21 and is arranged inside the fixed sleeve 1, and the lower end extends out of the fixed sleeve 1 and is connected to a limiting block 23 through a connecting rod 22. The limiting block 23 is connected to the pressure base 3, specifically: a movable groove 31 is provided on the pressure base 3, and a limiting plate 4 is connected to the upper end of the pressure base 3, and a limiting hole 41 is provided on the limiting plate 4. The connecting rod 22 passes through the limiting hole 41, and the limiting block 23 is arranged in the movable groove 31. Among them, the aperture of the limiting hole 41 is smaller than the outer diameter of the limiting block 23, so that when the limiting block 23 moves upward in the movable groove 31, it can be limited by the limiting hole 41.

[0026] The lower end of the fixed sleeve 1 is fixedly connected with a top ring 5, and the top ring 5 and the screw rod 2 can be threadedly connected or there can be a gap. The lower end of the pressure base 3 extends circumferentially to form a bottom pressure ring 32. A spring 6 is sleeved on the screw rod 2, and the upper end of the spring 6 is in contact with the top ring 5, and the lower end is in contact with the bottom pressure ring 32.

[0027] In this embodiment, initially, the spring 6 is in an elastic tension state; the screw 2 is rotated by the hexagonal head, and the screw 2 moves downward, and the pressing base 3 moves downward at the same time, until the lower end of the pressing base 3 presses against the packing layer; the screw 2 continues to move downward until the limit block 23 contacts the bottom of the movable groove 31, so that the screw 2 is tightly pressed against the pressing base 3, and then presses against the packing layer. At this time, the spring 6 is still in an elastic tension state, and the packing is pressed tightly by the elastic force of the spring 6 and the force of the screw 2 pressing and tightening the pressing base 3. When the adsorption tower is used for a long time, the packing is loose, and the low pressure of the pressing base 3 on the packing layer is reduced. At this time, the pressure on the packing layer is maintained by the pressure of the spring 6 on the pressing base 3 to ensure effective filtration of the packing.

[0028] In the above process, when the screw rod 2 moves downward and hits the bottom of the movable groove 31, the screw rod 2 will continue to rotate for further compaction. However, at this time, the bottom of the screw rod 2 and the bottom of the movable groove 31 have sliding friction. Therefore, in this embodiment, the bottom of the movable groove 31 is set to be bowl-shaped, and the bottom of the limit block 23 is set to be hemispherical, so as to reduce the friction between the limit block 23 and the movable groove 31, so as to make the compaction process more stable.

[0029] In addition, a plugging cap 7 is provided on the top of the fixed sleeve 1, and the plugging cap 7 can be threadedly connected to the fixed sleeve 1. The provision of the plugging cap 7 can increase the sealing performance of the tower pressing device to prevent gas from escaping from the tower pressing device; in addition, the plugging cap 7 can prevent impurities from entering the fixed sleeve 1 and affecting the use of the screw 2.

[0030] Example 2

[0031] like Figure 4 As shown, based on the structure of embodiment 1, the fixing sleeve 1 and the pressing ring 5 are detachably arranged, and the pressing ring 5 is threadedly connected to the screw rod 2. At the same time, a plurality of guide rods 8 parallel to the screw rod 2 are connected to the lower end of the fixing sleeve 1, and the lower ends of the guide rods 8 pass through the pressing ring 5.

[0032] In addition, the screw rod 2 is divided into a positive thread segment 2 a and a negative thread segment 2 b , wherein the positive thread segment 2 a is threadedly connected to the fixing sleeve 1 , and the negative thread segment 2 b is threadedly connected to the top ring 5 .

[0033] In this embodiment, initially, the spring 6 can be in a free state; the screw 2 is rotated by the hexagonal head, so that the screw 2 moves downward and pushes against the pressing base 3 to press the packing layer; at the same time, the top ring 5 rotates relative to the screw 2, moves away from the fixed sleeve 1 along the guide rod 8, and presses against the spring 6, so that the spring 6 has a driving force to press the pressing base 3 downward. At this time, the multiple packings of the pressing base 3 are pressed tightly by the elastic force of the spring 6 against the pressing base 3 and the pressing force of the screw 2 against the pressing base 3. When the adsorption tower is used for a long time, the packing is loose, and the force of the screw 2 pressing the pressing base 3 and then pressing the packing is reduced, but the spring 6 maintains the elastic force against the pressing base 3, so that the pressing base 3 continues to keep pressing the packing, thereby ensuring the adsorption effect.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
