Abstract

PURPOSE:To miniaturize each air supply apparatus to the best possible extent and to avoid the loss of an installation space and operation cost, by dividing a part of functions possessed by each air supply apparatus while functionating the divided functions in intensive manner. CONSTITUTION:Plural lines of painting booths 6 are formed along with conveyor lines of objects to be painted in the downstair chamber of a two-storied building while a plurality of blowers 10 each sending air to each booth 6 through an air sending duct 7 are provided in the upstair chamber 1 thereof and a plurality of make-up air generators 9 are provided therein. In addition, a make-up air distributor 20 connected to the side of the air outlet 9a of each air generator 9 and having an emitting port 20a in the vicinity of the suction port 10a of each blower 10 is provided to form the internal space of the upstair chamber 1 into one common-use air supply chamber. By this mechanism, the dust removing and humidifying functions of an air supply apparatus can be used in common by a single dust removing filter and a single humidifier and the air sending amount of the air generators is reduced to only 1/2 on the basis of the total air feeding amount of the blowers 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is mainly applicable to painting factories and the like.
This is an air supply device for a paint booth that supplies make-up air with adjusted temperature and humidity to the paint booth that paints the automobile bodies etc. that are transported for the first time. , relates to an air supply system for a painting booth, which is equipped with a plurality of blowers that blow air into an outside painting booth through a ventilation duct, and one or more make-up air generators that have a built-in heater and humidifier. .

One of the commonly known types of air supply systems for painting booths is the one constructed as shown in Figure 12 (A). A plurality of forced air supply lines (every 7 units) are installed corresponding to the multiple painting booths installed on the lower floor of the building, and the upper floor room (multiple air supply devices in one unit) is connected to each other. Each of these multiple air supply systems (A) is equipped with two dust removal filters (2), a heater (8), and a humidifier (4) in its casing. Each device (
Each of the air supply devices (A') is relatively large, and most of the space inside the upper floor room (1') (10 m) is occupied by the four air supply devices (A'), excluding those air supply devices (A')'. The space left behind has become dead space with little utility, and there is some waste in the entire facility, including the building.In particular, the casing of each air supply device and the wall of the building have become double-walled, making construction difficult. It was uneconomical in terms of cost.

In view of the above-mentioned circumstances, the present invention aims to miniaturize each air supply device as much as possible by dividing a portion and all of the functions and functions of each air supply device described in iiJ and integrating them into functions. The purpose of this method is to eliminate the space and economic losses of the above-mentioned conventional methods.

The characteristic configuration of the present invention, which has been made to achieve the above object, is that, in an air supply device for a snow-covered painting booth, the air supply device is connected to the air outlet side of the dust removal filter make-up air generator in contact with the outside air intake port, and A make-up air distributor having a discharge port near the suction port of the blower is provided, and the total air volume of the make-up air generators in the room is half of the total air volume of the plurality of air blowers. / Below VCt1 ~ is formed.

The effects of the present invention having such a characteristic configuration are as follows.

1) Multiple air supply devices can perform the functions of dust removal and humidification in order to turn high-temperature outside air into make-up air suitable for supplying each painting booth to each painting booth during the summer. The single dust removal filter and humidifier installed at the outside air intake in the upper floor rooms are used in common, and multiple inlet air systems installed in each forced air supply path are used during the winter. It can be constructed with a small make-up air generator that has only built-in equipment that is sufficient to heat and humidify the low-temperature outside air in areas such as Therefore, most of the interior space on the upper floor, excluding the space occupied by multiple make-up air generators, can be effectively shared as an air supply room for each make-up generator. This eliminates the need for multiple equipment casings, eliminates the need for double walls, and allows the entire facility, including the building, to be made smaller and more economical.

Next, the implementation of the configuration of the present invention will be explained based on the drawings.

As shown in Figures 1 and 2 (a) and (b), in the lower floor room (5) of the two-story building, there is a preheating booth (6a) and a coating Painting booth 7, (6) consisting of a painting booth (6b) and a setting booth (6c).
