(イ) 産業上の利用分野
本発明はバグフイルター式集塵機における袋状
布地過部材の洗浄装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a cleaning device for a bag-like fabric member in a bag filter type dust collector.
(ロ) 従来の技術
従来、袋状布地過部材を使用した洗浄装置の
洗浄手段は、通常、過室内に配設された多数の
スプリングスペーサー付袋状布地過部材の片側
から正負の空気圧を交互に作用させ、それにより

積した塵埃を払い落していた。(b) Prior Art Conventionally, the cleaning means of a cleaning device using a bag-like fabric over member usually alternately applies positive and negative air pressure from one side of a bag-like cloth over member with a large number of spring spacers disposed inside the overflow chamber. Alternatively, only positive air pressure can be pulsed from the clean air side of the bag-like fabric lining by a device separate from the sieve, thereby blowing away dust accumulated on the contaminated air side of the fabric lining. It was supplied as air pressure to blow away the dust that had accumulated on the contaminated air side.
(ハ) 発明が解決しようとする問題点
前記従来の洗浄手段は多数の過室内に配設さ
れた過体を洗浄するに当たり、過室を順次に
洗浄するので、先ず、一室だけ過運転を中止し
て、この過室だけを洗浄し、洗浄完了と共に運
転を再開して、同時に次の過室の過運転を中
止し、洗浄を行なうので、集塵装置の過面積は
常に一室分だけ失なうことになり、この失なわれ

を付加して所定の過面積を得るのが通常手段で
あつた。(c) Problems to be Solved by the Invention The conventional cleaning means described above cleans the over-chambers in sequence when cleaning over-bodies disposed in a large number of over-chambers, so first, only one chamber is over-operated. The excess area of the dust collector is always the same as that of one room. In order to compensate for the excess area corresponding to this lost area, the usual means was to add a room outside to obtain a predetermined excess area.
又、洗浄時正負の空気圧を交互に作用させる為
にはダクトを配設したり、切換えダンパーを用い
たり、種々、設備を必要とすると共に過室を順
次に洗浄しようとする為、夫々、独立した過室
を形成しなければならず、過室と過室との仕
切り壁も必要になり極めて不経済である。 In addition, in order to apply positive and negative air pressure alternately during cleaning, various equipment such as installing ducts and using switching dampers is required. This is extremely uneconomical since it is necessary to form a large overchamber and a partition wall between the overchambers is also required.

This is to brush off the accumulated dust.
(ヘ) 実施例
以下、本発明一実施例を図面を参照しながら説

にスプリング３が複数本張られている。 The overbody shown in FIG. 1 according to the present invention is fitted into the elongated hole 11 of the overbody mounting wall 12 of the dust collector and fixed with bolts, but the frame 1 of this overbody is made of a tube. It is bent into a U-shape, and one end of its upper part is welded and fixed to the upper part of the overbody fixing plate 4, and the other end of the lower part is welded and attached to the coupling 14 which penetrates the fixing plate 4 and is internally threaded. There is. Reinforcement of the frame 1 and spring 3 are provided on the open side of the frame 1 and the opposite side, respectively.
Flat bars 13 and 13' are attached to serve as fixing plates, respectively, and a plurality of springs 3 are stretched between the flat bars 13 and 13'.
フレーム１は管で製作されているから、内部に
流体を通すことができるので、このフレーム１の
下部に複数個の孔３０を開けて、必要によりそこ
にノズルを取付けることにより、フレーム１に洗
浄装置の構成の一部を兼用させる。 Since the frame 1 is made of a tube, it is possible to pass fluid through the interior, so by drilling a plurality of holes 30 in the lower part of the frame 1 and attaching nozzles there as necessary, the frame 1 can be cleaned. Part of the device configuration is shared.

ように配管接続する。 A nozzle 6 is attached to each hole 30 to form an air header, and a diaphragm valve 8 is installed to generate an impactful air pulse at the open end of the frame 1, and an air bleed pilot is installed to operate the nozzle 6. Attach the solenoid valve 9 and connect the piping as shown in FIG.
ダイヤフラム弁８の構造及びパイロツト電磁弁
９の構造は第４図に示すようになつている。 The structure of the diaphragm valve 8 and the structure of the pilot solenoid valve 9 are as shown in FIG.

し上げて高圧空気は弁２４を通り、フレーム１に
瞬時パルスエアーとして供給されて空気噴射部か
ら過体の清浄空気側に噴射される。 High-pressure air (5 to 7 kg/cm 2 ) from the compressor is supplied to the diaphragm valve 8 from the air supply pipe 10 shown in FIG. 3, and in FIG. It passes through the hole 19, flows into the A part, reaches the A' part of the pilot solenoid valve 9 connected by the conduit 20, and the pilot valve 9
Since the valve 22 is closed by the spring 21, the pressure in the B, A, and A′ parts becomes equal momentarily.
Since the diaphragm 23 is pushed down by the pressure and closes the valve 24, no air is supplied to the frame 1, but when a pulse signal from the timer momentarily flows through the conductor 25, the electromagnetic coil 26 is momentarily excited. The movable core 27 is sucked in, which opens the valve 22, and the high-pressure air in parts A and A' is injected into the atmosphere from the exhaust port 28, so part B has a higher pressure than part A, and this pressure causes the diaphragm to close. 23 is momentarily pushed up, the high-pressure air passes through the valve 24, is momentarily supplied to the frame 1 as pulsed air, and is injected from the air injection section to the clean air side of the overbody.
タイマーからの導線２５への信号は瞬間的であ

のである。 Since the signal from the timer to the conductor 25 is instantaneous and a pulse signal of 0.04 to 0.36 seconds, it is quite shocking, so the air pressure supplied instantaneously is applied to the spring shown in Figure 1. 3 instantaneously impactively vibrates and instantaneously hits the bag-shaped fabric over member 2 to give impulsive vibrations, and the bag-like cloth over member 2 causes instantaneous impact flapping, which is extremely effective. It can be used to remove dust.

できる。 Next, regarding the number of injection nozzles 6 to be attached, three per meter of frame length is appropriate. In addition, a rubber plug 7 is installed in the tube near the bent portion at the bottom of the frame 1 in FIG.
is inserted and arranged to reduce the transmission space of the impact air pressure in the frame so that air can be effectively injected into the inside of the bag-like fabric over member. As shown in the figure, a plurality of overbodies can be washed by one diaphragm valve 8 and one pilot solenoid valve 9.

Figure 2B shows a nozzle in the shape of a hanging peg, and an effective nozzle inner diameter of 4 to 10 mm is effective. FIG. 2C shows an example of a nozzle having a curve opposite to that of a hanging spigot, and an effective nozzle inner diameter of 4 to 10 mm is similar to the hanging spigot shape nozzle.
