Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an equipment assembly device in which a number of equipments having the function of fully pumping supplied gas at a pressure lower than atmospheric pressure are arranged in clusters.

[Technical background of the invention]

Some types of blunts require multiple stages of nearly identical equipment each having the function of pumping gas at a pressure lower than the supplied atmospheric pressure.

Such a so-called equipment gathering device is generally configured as shown in FIG. 1, a part of which is extracted.

That is, a plurality of device bodies (not shown) each having a gas pressure feeding function are housed in a case 1 and arranged on the same plane, and gas at a pressure lower than atmospheric pressure is introduced into each case 1 through the top lid of each case 1. The piping 2 and the piping 3 for discharging pressurized gas in the device body in each case 1 are provided to pass through the piping 2 in an airtight manner, and the ends of these pipings 2 and 3 located outside of each case 1 are connected to each case 1. The pipes 4 and 5 are connected in common to pipes 4 and 5 arranged above the pipes.

Note that each case 1 is usually composed of a cylindrical body 6, and an upper lid 2 and a lower lid 8 that close the upper and lower openings of the cylindrical body 6.

[Problems with background technology]

However, the equipment collection device configured as described above has the following problems.

In other words, since each piece of equipment is formed and installed independently, there is a problem that the entire equipment assembly becomes large and requires a large installation area. Due to the introduction of gas, the upper cover 7 and lower cover 8 must be attached using a method such as melt-tightening using metal gaskets, or an airtight welding method. It took a long time (1. There was also the problem that the entire device became expensive. [Objective of the Invention] The present invention was made in view of the above circumstances, and its purpose is to When multiple devices with nearly identical configurations that have the ability to pump low-pressure gas are assembled together, it is easy to maintain airtightness from the atmosphere, and it also reduces the installation area and simplifies manufacturing and assembly work. An object of the present invention is to provide an equipment gathering device that can achieve the following.

[Summary of the invention]

The device focusing device of the present invention is a device having a substantially identical configuration, each of which is equipped with a gas pressure feeding function in each storage chamber of a case having a plurality of storage chambers in which the wall portion located between adjacent devices is shared. It accommodates the main body and constitutes an equipment assembly. Then, the equipment assembly is housed in an airtight container, and a means for supplying gas at a pressure lower than atmospheric pressure in parallel into a pre-accommodating chamber of the equipment assembly, and a gas pumping function of each of the equipment bodies. and a communication path for communicating an independent space formed between the airtight container and the equipment assembly to the storage chamber of one of the equipment assembly. It has become a thing.・
[Effects of the Invention] With such a configuration, as a case for accommodating each device main body, a single case is formed by arranging a plurality of accommodating chambers in such a manner that the wall portion located between adjacent ones is shared. As a result, each device body can be arranged in a sufficiently dense manner, and as a result, the entire device assembly device It is possible to reduce the weight, size, and installation area of the device.

Furthermore, since the equipment assembly is housed in the airtight container, the airtight container can provide airtightness between the equipment assembly and the atmosphere. Since each equipment body housed in each housing chamber of the equipment assembly has almost the same configuration and the pressure distribution within each housing chamber is almost equal, airtightness between each housing chamber can be maintained by extremely simple means. realizable.

Therefore, compared to a conventional device in which independent devices are arranged in a group, the airtight maintenance structure can be simplified, and as a result, manufacturing and assembly can be facilitated. Furthermore, since the independent space formed between the airtight container and the equipment assembly is made to communicate with one storage chamber, the continuous tracing section is connected to the partition wall section that partitions the space and each storage chamber. If provided, the pressure difference between the inside and outside of the partition wall can be reduced to zero, and as a result, the structure for maintaining airtightness between the storage chambers can be further simplified. In other words, it is possible to simplify the airtight maintenance structure and at the same time prevent gas mixing between the respective storage chambers. Therefore, the manufacturing cost and manufacturing time of the entire equipment assembly device can be further reduced.

Since each device body is formed in a shared relationship, each device body can be arranged sufficiently densely, and as a result, the device body is It is possible to reduce the weight, size, and installation area of the entire gathering device.

Furthermore, since the airtight container 11 is formed to maintain sufficient airtightness between the inside of the airtight container 11 and the outside atmosphere, each storage chamber 12a.

12b, 1, 2e, and 12d can be maintained airtight by extremely simple means. That is, as in the embodiment, each of the storage chambers 12a+ zzb and IZc.

Each accommodation space can be kept airtight by simply being press-fitted into the openings at both ends of the columnar space formed by the upper lid 23 and lower lid 24't and the partition wall 22 of 12d. Therefore, unlike the conventional device, the air-tight maintenance structure can be simplified instead of a device in which independent devices are arranged in a group, so that the above-mentioned effects can be obtained after all.

Further, an independent space 27 formed between the lower surface of the case 13 and the airtight container 11 is communicated with the housing 12b through the hole 28, and an independent space 27 formed between the upper surface of the case 13 and the airtight container 11 is made to communicate with the housing 12b through the hole 28. Another independent space 29 is provided in the storage room 12.
