[0016]
FIG. 2 is a longitudinal sectional view of a part of the dehumidifying device, and particularly shows only one row side of the adsorption cylinder 4 in a section along the width direction.
The inlet head 2 is provided with an introduction path 10 for introducing wet compressed gas into the apparatus along the longitudinal direction, and is provided with a guide port 11 communicating with the introduction path 10 only at a position facing the adsorption cylinder 4. . A lower positioning plate 12 is placed on the top surface of the inlet head 2, and a bent piece 12 a on the side is attached and fixed to the inlet head 2 via a fixing screw 13.
[0017]
The lower positioning plate 12 is obtained by sheet metal processing of a plate body having a predetermined plate thickness. A plurality of suction cylinder openings 12b are provided at predetermined positions, and the lower ends of the suction cylinders 4 are fitted. ing.
[0018]
The adsorption cylinder 4 is composed of a cylinder body 4a whose upper and lower end surfaces are open and upper and lower flange portions 4b provided along the upper and lower end surfaces of the cylinder body 4a, and a porous plate 16 is detachable inside these flange portions. Provided. An adsorbent 17 made of activated alumina, silica gel, zeolite, or the like is tightly packed between the perforated plates 16.
[0019]
Furthermore, the concave groove 4c is provided along the end surface of the upper and lower flange portions 4b, and the packing material 18 is fitted therein. Each packing material 18 protrudes from the end surface of the upper and lower flange portions 4b, and in the assembled state, the packing material 18 is in close contact with the lower surface of the outlet head 3 and the upper surface of the inlet head 2 to form these seals.
[0020]
The outlet head 3 is provided with a lead-out path 19 to which a dry gas supply path is connected along the longitudinal direction, and is provided with a guide port 20 communicating with the lead-out path 19 only at a position facing the adsorption cylinder 4. . The upper positioning plate 21 is fitted to the lower surface of the outlet head 3, and the side bent pieces 21 a are attached and fixed to the outlet head 3 via the fixing screws 13.
[0021]
The upper positioning plate 21 is obtained by subjecting a plate body having a predetermined plate thickness to sheet metal processing. A plurality of suction cylinder openings 21b are provided at predetermined positions, and the upper ends of the suction cylinders 4 are fitted. .
[0022]
The through bolt 7 is inserted through the bolt hole 14 provided in the inlet head 2 and the positioning plate 12 and the bolt hole 22 provided in the outlet head 3 and the positioning plate 21, and the nut is screwed together. The heads 2 and 3 are fastened and fixed via the suction cylinder 4.
[0023]
FIG. 2 shows through-bolts 7A at four corners to which push-up nut bodies 8 to be described later are attached.
The through bolt 7A is inserted into a bolt hole 14 provided in the inlet head 2 and the positioning plate 12, and is fastened and fixed to the inlet head 2 and the positioning plate 12 by screwed nuts 15 and 15. The upper end portion of the through bolt 7A extends to the vicinity of the lower surface of the outlet head 3, and a screw portion 25 is provided at the end portion.
[0024]
The push-up nut body 8 has a screw hole 26 into which the threaded portion 25 of the upper end portion of the through bolt 7A is screwed along the axis from the lower end surface. Further, a hexagonal nut portion 8a whose outer periphery from the lower end surface is longer than the axial length of the screw hole 26 is formed, and a bolt portion 8c having a screw portion 8b is integrally connected to the upper side of the hexagonal nut portion 8a. Yes.
[0025]
The screw portion 8b has the same screw diameter as the through bolt 7A, and the diameter of the hexagon nut portion 8a is set larger than the screw diameter of the bolt portion 8c. Therefore, the bolt portion 8 c is inserted into the outlet head 3 and the bolt hole 22 of the upper positioning plate 21, and the upper end shoulder portion of the hexagon nut portion 8 a supports the outlet head 3 via the upper positioning plate 21. .
[0026]
Since the nut 15 is screwed to the screw portion 8b of the push-up nut body 8, the outlet head 3 and the upper positioning plate 21 are fastened and fixed by the hexagon nut portion 8a and the nut 15.
[0027]
In the dehumidifying device configured as described above, wet compressed air is guided to the adsorption cylinder 4 on one side of the adsorption cylinders 4 arranged on the left and right sides, and moisture is adsorbed and dehumidified by the adsorbent 17 so as to be dried air. Instead of being supplied to a predetermined supply destination. At the same time, part of the obtained dry air is guided to the adsorption cylinder 4 in the other row, and moisture is desorbed and regenerated from the adsorbent 17 whose capacity has been reduced due to moisture absorption in the previous stage, and further this moisture is purged to the outside. .
[0028]
The dehumidification drying of the compressed air in the first column of adsorption cylinders 4 and the regeneration of the adsorbent 17 in the other column of adsorption cylinders 4 are performed in parallel at the same time. The switching valve is switched to supply dry air continuously.
[0029]
Since the adsorbent 17 deteriorates after a lapse of a predetermined period, the adsorbent 17 is replaced for all the adsorption cylinders 4 before that. Hereinafter, the replacement work of the adsorbent 17 will be described with reference to FIG.
[0030]
First, the through bolts 7 other than the four corners are loosened so that the outlet head 3 can be moved by a predetermined amount. Next, after loosening the nut 15 screwed onto the upper portion of the push-up nut body 8 by the same amount, the push-up nut body 8 is urged to rotate in the ascending direction.
[0031]
The outlet head 3 and the upper positioning plate 21 are supported by the push-up nut body 8 and tilted almost horizontally by rotating the push-up nut bodies 8 little by little and with a substantially uniform amount. Hold and rise.
[0032]
When the suction cylinder opening 21b of the upper positioning plate 21 comes out of the upper end of the suction cylinder 4, the restraint on each suction cylinder 4 is released, and each suction cylinder is movable in the axial direction.
[0033]
Further, the push-up nut body 8 is urged to rotate in the same direction to raise the outlet head 3 and the upper positioning plate 21 so that the lower end portion of the suction cylinder 4 can be removed from the suction cylinder opening 12b of the lower positioning plate 12. When it is ready, the suction cylinder 4 is taken out of the apparatus.
[0034]
Actually, in order to further reduce the size of the apparatus, almost no gap is set between the adjacent suction cylinders 4. Therefore, the fingers are inserted into the gap between the suction cylinders and the circumferential surface of the suction cylinder 4 is gripped with both hands. I can't. Therefore, the outlet head 3 and the upper positioning plate 21 are further raised, and a finger is hooked on the upper end portion of the suction cylinder 4 so as to be tilted and taken out without interfering with the plate 21.
[0035]
All the deteriorated adsorbent 17 in the adsorption cylinder 4 is discharged, and a new adsorbent 17 is filled in the adsorption cylinder 4 instead, and then the adsorption cylinder 4 is set in the apparatus again. At this time, since the push-up nut body 8 holds the upper positioning plate 21 and the outlet head 3 in the raised position, the attachment of the suction cylinder 4 to the apparatus is very easy.
[0036]
When the replacement of the adsorbent 17 in all the adsorption cylinders 4 is completed and the adsorbent 17 is again placed at a predetermined position in the apparatus, the push-up nut body 8 is rotated in the opposite direction to lower the outlet head 3 and the upper positioning plate 21. .
[0037]
Then, as shown in FIG. 2, the outlet head 3 is returned to the state where it is placed on the sealing material 18 at the top of the suction cylinder 4, and the upper nut 15 is fastened to the push-up nut body 8, thereby completing all operations.
[0038]
In this way, the suction cylinder 4 can be attached / detached by lifting and holding the outlet head 3 which is a heavy object by a relatively simple operation of only rotating and energizing the push-up nut body 8 without using a heavy machine. Therefore, the labor can be reduced.
[0039]
Even if a large number of through-bolts 7 are used, only a necessary amount is loosened when the adsorbent 17 is replaced, and it is not necessary to remove the adsorbent 17 from the apparatus. Since no heavy machinery is used at all, the space for moving heavy machinery and the work space above the device are not required, and there are fewer restrictions on the installation location.
[0040]
The push-up nut body 8 is not limited to the above-described configuration as long as the same effect as that described above can be achieved as a result.
As an example, as shown in FIG. 4A, through bolts 70A and 70B that are divided into two parts in the vertical direction, screw parts a and b in different directions are provided at opposite ends of each other. For example, the threaded portion a of the upper through-bolt 70A is a right-hand thread, and the threaded portion b of the lower through-bolt 70B is a left-handed screw.
[0041]
The push-up nut body 8A has a hexagonal column shape, and is provided with screw holes a1 and b1 in different directions along the axis and from both the upper and lower end faces. Then, the screw portions a and b of the upper and lower through bolts 70A and 70B are screwed into the screw holes a1 and b1 of the push-up nut body 8A having the same direction.
[0042]
As a result, when the push-up nut body 8A is urged to rotate in a predetermined direction, the space between the upper and lower through-bolts 70A and 70B is increased, and the outlet head 3 is pushed up by the push-up nut body 8A. If the rotation force is applied in the reverse direction, the distance between the upper and lower through-bolts 70A and 70B is shortened and the outlet head 3 is pushed down.
[0043]
Note that the screw directions of the screw portions a and b and the screw holes a1 and b1 may be reversed, and a so-called turnbuckle is used instead of the push-up nut body 8A on the premise that a reverse screw is provided. Also good.
[0044]
Moreover, as shown to FIG. 4 (B), the structure provided with the through-bolt 7 which is not divided | segmented, and screwing up the pushing-up nut body 8B which is a simple commercially available nut here may be sufficient. In other words, if the weight of the innerlet head 3 is received by the push-up nut body 8B, the position of the innerlet head 3 is of course changed in the vertical direction due to the rotational biasing of the nut body 8B.
[0045]
Depending on the set dehumidifying capacity, some dehumidifying devices have larger or smaller devices than those described above, and the number of through-hole bolts 7 increases or decreases as well as the number of adsorption cylinders 4. Therefore, the positions and the number of the push-up nut bodies 8, 8A, 8B also change as necessary.
[0046]
【The invention's effect】
As described above, according to the present invention, when replacing the adsorbent, the outlet head, which is a heavy object, can be moved up and down relatively easily to facilitate the attachment and detachment of the adsorption cylinder. In addition, the necessary work space is very small, and there is an effect that the restriction on the installation place is reduced.
