Description

[Detailed description of the invention] (Field of industrial application) The present invention is a compression device, more specifically, a compression device in which a compressor main body containing a compression element and an accumulator connected to the suction side of the compression element are arranged side by side. Regarding.

(Prior Art) Conventionally, the accumulator A used in this type of compression device is described in, for example, Japanese Utility Model Application Publication No. 50-105007, and as shown in FIG. A filter is disposed in the casing C, and a suction pipe T is extended from the lower side of the casing C, and the tip of the suction pipe T protrudes into the side of the compressor main body CP. It is fixed to the provided joint pipe P by welding means or the like.

(Problem to be solved by the invention) By the way, in the above-mentioned accumulator A,
Since the casing C is an integral type with a sealed structure, if the filter inside the casing C becomes clogged, the filter cannot be cleaned or replaced.
Therefore, normally, the welded part between the suction pipe T and the joint pipe P is removed and the entire accumulator A is replaced. However, when doing so, the replacement cost is high, and moreover, the welded part is removed. When heat is applied to the welded portion for removal, distortion may occur on the compression element side within the main body CP, which may adversely affect compression efficiency.

The present invention was developed in view of the above-mentioned problems, and its purpose is to prevent thermal effects on the compression element side in the compressor main body when the filter in the accumulator becomes clogged. To provide a compression device in which the accumulator can be easily disassembled without giving anything, and the filter can be cleaned and replaced at low cost.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a compression device in which a compressor main body 1 having a compression element therein and an accumulator 2 connected to the suction side of the compression element are arranged side by side. , the accumulator 2 is divided into an upper case 21 and a lower case 22, the lower case 22 is fixed to the compressor main body 1, and the upper case 21 is detachably attached to the lower case 22, while A suction pipe 3 extending to the compression element is provided in the lower case 22, and a filter 7 is installed inside the accumulator 2 so that it can be replaced by removing the upper case 21. .

(Function) If the filter 7 becomes clogged, remove the upper case 21 of the accumulator 2 from the lower case 22 and clean or replace the filter 7 installed inside the accumulator 2. By doing so, service costs are reduced, and since heat is not applied to the compression element side of the compressor main body 1 as in the conventional case, the heat of the compression element is reduced. It is possible to eliminate distortion caused by

(Example) Examples will be described with reference to the drawings.

FIG. 4 shows the overall structure of the compression device, which includes a compressor main body 1 containing a compression element (not shown),
an accumulator 2, the accumulator 2
The tip of a suction pipe 3 extending from the lower side of the main body 1 is connected to a joint pipe 4 protruding from the lower side of the main body 1, and fluid from the accumulator 2 is transferred to the compression element through the suction pipe 3. At the same time, the accumulator 2 is integrally fixed and held at a side position of the main body 1 via a support 5.

As shown in FIGS. 1 and 2, the accumulator 2 is divided into two parts from the middle part in the vertical direction, and is formed by an upper case 21 and a lower case 22. A filter 7 supported by a vertical plate 6 is disposed on the inner upper side.
At the same time, a support plate 8 is fixed to the lower case 22, and the suction pipe 3 connected to the compressor main body 1 side is integrally supported on the lower case 22 side via the support plate 8. At the same time, the upper case 21 is detachably attached to the lower case 22.

Specifically, first and second flanges 23 and 24 facing each other are integrally provided at the upper and lower ends of the upper case 21 and the lower case 22, and each flange 23 and 24 is provided with a plurality of through holes. 25
and a screw hole 26, and this upper side through hole 25
and the fixing bolts 9 into the lower side screw holes 26 respectively.
By inserting and fixing each flange 2
The respective cases 21 and 22 are removably attached via 3 and 24.

Further, a connecting flange 10 is provided at the tip of the upper end of the upper case 21 at a portion facing the filter 7.
an outflow pipe 12 that connects the connecting pipe 11 with a
A connecting flange 13 connectable to the connecting flange 10 is provided, and each of these flanges 10, 13
are removably connected.

If the filter 7 in the upper case 21 becomes clogged, remove the fixing bolts 9 of the flanges 23, 24 provided on the cases 21, 22, and connect the connecting pipe 11. The connecting flanges 10 and 13 provided on the outflow pipe 12 are removed, the upper case 21 is separated from the lower case 22, and the filter 7 installed in the upper case 21 is cleaned or replaced, or the upper case 21 is removed. The whole thing is replaced.

Further, the filter 7 is connected to the lower case 22.
The filter 7 may be disposed near the opening of the filter 7, and when the upper case 21 is removed from the lower case 22, the filter 7 may be opened to the outside and each filter 7 may be cleaned or replaced. It is.

Further, as shown in FIG. 3, the support 5 that holds the accumulator 2 on the compressor main body 1 includes a mounting plate 51 extending in the vertical direction that is fixed in contact with the outer circumferential wall of the main body 1, and It consists of a support plate 52 extending horizontally from the upper side of the plate 51, a through hole 53 is formed in the center of the support plate 52, a screw hole 27 is provided in the second flange 24, and a screw hole 27 is provided in the second flange 24. 23 is provided with a stealth hole 28 in a non-penetrating state, and the support plate 52 is connected to the second
The accumulator 2 is held on the main body 1 via the support 5 by applying it to the lower surface side of the flange 24 and screwing the fixing bolt 14 from the through hole 53 of the support plate 52 into the screw hole 27. That's what I do.

Also, on both sides of the through hole 53 in the mounting plate 52, through holes 54, 54 are provided for tightening the mounting plate 52 together with the respective flanges 23, 24.
