本考案は集塵機付き塗布装置に関し、特に管類
の外面に金属を溶射により塗布可能な集塵機付き
塗布装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating device with a dust collector, and more particularly to a coating device with a dust collector that can coat the outer surface of pipes with metal by thermal spraying.
管をダクタイル鋳鉄により遠心鋳造したような
場合には、腐食防止の観点からその外面に亜鉛な
どの金属を溶射により塗布することが多い。この
溶射の際には、管に付着しなかつた亜鉛が凝固し
て粉粒状となり、これが塵芥となつて空気中にま
き散らされるという問題がある。 When a pipe is centrifugally cast using ductile cast iron, its outer surface is often coated with a metal such as zinc by thermal spraying to prevent corrosion. During thermal spraying, there is a problem in that the zinc that does not adhere to the pipe solidifies into powder particles, which become dust and are scattered into the air.
そこで従来は、溶射を行なう場合、作業場全体
を密閉した空間とし、作業者は外部よりエアーを
供給される防塵服を着用して作業を行なつたり、

適当であるうえに作業者の負担が重いという欠点
があり、また後者は作業者の負担が軽減されるか
わりに集塵設備に大容量のものを必要とするとい
う欠点がある。 Conventionally, when thermal spraying was carried out, the entire workplace was kept in a sealed space, and workers wore dust-proof clothing that was supplied with air from outside.
A large-capacity dust collector is installed at the thermal spraying location to carry out the work. However, the former method is unsuitable for assembly-line work and has the disadvantage of placing a heavy burden on the worker, while the latter requires a large-capacity dust collection equipment, although it reduces the burden on the worker. There is a drawback.
そこで本考案は、小型で簡単な装置により能率
良く集塵が行なえるようにするうえに、流れ作業
にも適するようにし、しかも作業者の負担を軽減
可能なようにすることを目的とするものである。 Therefore, the purpose of this invention is to make it possible to efficiently collect dust using a small and simple device, to make it suitable for assembly line work, and to reduce the burden on workers. It is.
この目的を達成するため本考案は、開口端が被

ものである。 In order to achieve this purpose, the present invention provides a double cylinder whose open end faces the object to be coated, and the inner cylinder of this double cylinder has a bottomed structure, and a coating agent injection gun is installed inside the inner cylinder. An annular space formed between the outer cylinder and the outer cylinder is communicated with the dust collector, and a cylindrical sliding part is provided at the open end of the outer cylinder so that it can be moved in and out. The gap can be adjusted.

た、二重筒を用いたため、噴射ガンの噴射音に対
する防音効果も得ることができる。 Therefore, by reducing the distance between the open end of the double tube and the object to be coated, the air suction speed around the double tube can be increased, and dust can be collected reliably around the injection gun. Dust can be efficiently collected locally at the application site and its vicinity, and by collecting dust from between the inner and outer cylinders of the double cylinder, the suction speed can be increased and the dust can be guided more reliably to the dust collector. By moving the slide part back and forth, the distance between the injection gun and the object to be coated can be maintained at an optimal constant value, and the distance between the open end of the double barrel and the object to be coated can be maintained without changing the position of the injection gun. Only the gap between the two can be adjusted. As a result, dust can be collected reliably locally using a dust collector with a capacity of 1.5 to 2 times the amount of air used by the injection gun, reducing equipment costs.
Savings in operating costs and installation space can be achieved. Moreover, since a double cylinder is used, it is possible to obtain a soundproofing effect against the injection noise of the injection gun.

In the figure, 1 is a ductile cast iron tube formed by centrifugal casting, and is supported in the horizontal direction by a driving side support roller 3 and a driven side support roller 4 on a cart 2 so as to be rotatable around its axis. There is. The trolley 2 is movable on rails 5 in a direction perpendicular to the plane of the paper, and the tube 1 can be moved in this direction. Further, the driven side support roller 4 can be moved toward and away from the drive side support roller 3 by operating the handle 6, and is configured to be able to appropriately support pipes 1a of different diameters.

になつている。 7 is a coating device with a dust collector according to the present invention;
It is composed of a double cylinder 10 having an inner cylinder 8 and an outer cylinder 9, and its open end 11 faces the outer surface of the tube 1 as the object to be coated. The inner cylinder 8 has a bottomed structure having a bottom part 12, and an injection gun 14 is attached to the inside thereof via a support member 13. The spray gun 14 is supplied with a zinc wire 15 and compressed air, and is configured to melt the zinc wire 15 into a coating material and spray it onto the outer surface of the tube 1 by the action of the compressed air. Inner cylinder 8 and outer cylinder 9
An annular space 16 is formed between them, and this annular space 16 is communicated with a dust collector (not shown) via a duct 17. A slide portion 18 is formed at the tip of the outer cylinder 9, and the opening edge 19 of this slide portion 18 is formed into a curve that matches the outer surface shape of the tube 1. As the slide portion 18 moves in and out, the opening edge 19 and the tube are connected. The gap with the outer surface of 1 can be adjusted.
本装置７はこのような構成を有し、管１の軸方

つている。 The device 7 has such a configuration and is arranged opposite to the axial portion of the tube 1. In addition, the position can be adjusted both horizontally and vertically, so that work can always be performed properly even when the pipe diameter changes.

により塵芥の飛散が防止される。 According to the above configuration, zinc is sprayed from the injection gun 14 while the tube 1 is slowly rotated by the support rollers 3 and 4 and the trolley 2 is gradually moved.
This is applied to the entire outer circumference of the tube 1. At this time,
When a dust collector (not shown) is operated, an air flow as shown by the arrow A in the figure is generated, and the zinc that does not adhere to the pipe 1 and solidifies into powder particles passes through the annular space 16 and the duct 17 as dust, and then passes through the annular space 16 and the duct 17. The dust is collected by a dust collector, which prevents the dust from scattering.

る。 The gap between the opening edge 19 of the slide portion 18 and the outer surface of the tube 1 is adjusted according to the flow rate of the compressed air blown out from the injection gun 14, and the smaller the gap, the higher the efficiency. Further, the smaller the distance between the inner cylinder 8 and the outer cylinder 9 of the double cylinder 10, the higher the suction flow velocity, and the amount of dust scattered outside the cylinder can be reduced. Further, due to the double structure of the inner cylinder 8 and the outer cylinder 9, a soundproofing effect against the injection noise of the injection gun 14 can be expected.

減少した。 Next, an experimental example of the present invention will be explained. The amount of air used in the injection gun 14 is 30 m 3 / for the pipe 1 with a diameter of 600 mm.
min, dust collector capacity 50m 3 /min, opening edge 19 and pipe 1
The experiment was conducted with a gap of 10 mm between the outer surface of the The outer cylinder 9 is a square shape of 400mm x 400mm, and the inner cylinder 8 is 360mm x 360mm.
It was made into a rectangular shape of mm. As a result of the experiment, air was sucked in at a flow rate of 20 m/sec around the opening edge 19, and dust was almost completely collected. Also, the injection sound
At a distance of 1 meter, the number has been reduced from the previous 100 phones to 80 phones.

mm or less) is applicable to pipe 1A.
In the figure, a large bogie 2 runs on the broad gauge side of the rail 5.
In contrast, in FIG. 2, the tube 1A is supported by a small truck 2A running on the narrow gauge side of the rail 5. Furthermore, as the diameter of the tube 1A becomes smaller, the double tube 10 becomes relatively larger, so the one shown in FIG. A suction hood 20 is provided on the side so that even if debris flowing in this direction occurs, it can be collected.
