Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag filter exchanging device.

[0002]

2. Description of the Related Art In order to prevent environmental pollution, exhaust gas and combustion gas from factories and incinerators are introduced into a dust collecting tower 1 through an inflow pipe 2 as shown in FIG. It is collected in the suction chamber 4 and guided from the chamber 4 to the outside through the outflow pipe 5. By the way, since the bag filter 3 in the dust collecting tower 1 is clogged with time and the dust removal efficiency is lowered, it is necessary to replace it with a new one at an appropriate time. The replacement bag filter 3 is dropped from the upper chamber 4 into the tower, and is pulled out from the cleaning port (manhole) P to be removed, all of which are performed manually.

[0003]

The larger the volume of the bag filter used, the more labor is required for the above replacement work, and there is a problem of environmental pollution due to soot and dust remaining in the bag filter. . According to the present invention, the above work is automatically performed by developing a mechanical device with almost no labor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially cutaway explanatory view of a device of the present invention, and FIG. 2 is a usage state diagram thereof. Reference numeral 6 is a bag filter exchange and take-out device according to the present invention, 7 is a box body of a constant volume, 8 is an insertion port for a flexible hose bored at an upper portion of the box body 7, and 9 is an insertion port. It is a flexible hose.

Here, the flexible hose 9 has an appropriate length and has an inner diameter d that allows the exchange bag filter 3 described later to move, and a sling 10 such as a wire is inserted therein. The striations 10 are wound or unwound by reels provided oppositely to the respective ends of the flexible hose 9. That is, 11
Is a take-up reel at the insertion port 8 side of the flexible hose 4 in the box body 7, in which an electric motor 12 with a reducer is arranged on the box body 7, and the take-up reel 11 is provided on its rotation axis. Is attached and one end of the strut 10 is locked.

On the other hand, reference numeral 13 is a winding means for the exchange bag filter 3 which transfers the inside of the bending hose 9 installed in the box body 7 by means of the slings 10.
A disk 13b having a shaft 13a in the center on the extension line of the insertion port 8 is rotatably provided by a motor with a reduction gear (not shown). Reference numeral 14 is a hook for temporarily locking the bag filter when the bag filter is wound up.

On the other hand, reference numeral 15 is a reel which is provided on the outer edge of the distal end of the flexible hose 5 and which is used for paying out and winding up for the above-mentioned striations 10, and which can be electrically operated. The manual handle 15a is provided. At this point, the electric take-up reel 6 provided on the apparatus main body side is turned on / off and the dust collector described later is turned on / off.
An operation switch 16 for turning off is provided.

By the way, a box-shaped drawer 1 which can be slid outward and can be put in and taken out on the bottom surface of the box body on the apparatus body side.
7 is provided so that the soot and dust that fall into the box body during the winding work of the replacement bag filter can be temporarily stored and taken out to the outside. A hose attachment port 18 for a dust collector, which will be described below, is provided for constantly sucking and removing soot and dust that fall into the box body during the winding operation of the replacement bag filter.

Reference numeral 19 denotes a dust collector which is used together with the apparatus in the above-mentioned bag filter replacement work, which is a conventional apparatus for general use. 20 and 21 are dust collecting hoses for the device, and one (2
No. 0) has the same length as that of the flexible hose 9, and the other one (21) is said to be connected to the hose mounting port 18 in the device body 6. The former sucks soot and dust adhering to the bag filter directly when the bag filter is replaced, while the latter sucks dust that falls in the apparatus body 1.

FIG. 2 is a diagram showing the state of use, and 1 is a dust collecting tower into which exhaust gas and combustion gas from the same factory or incinerator as shown in FIG. 3 are sent. As shown in the drawing, a large number of bag filters 3 are vertically installed in the dust collecting tower 1 via cage retainers, and exhaust gas, combustion gas, and the like flow in from an inflow pipe 2 in an intermediate portion, and each bag filter is installed. 3 is led out from the upper suction chamber 4 through the outflow pipe 5 to the outside.

During the above-mentioned use, soot, dust, etc. adhere to the outer peripheral surface of each bag filter 3, causing clogging, and the decrease in filter efficiency progresses over time. Therefore, replacement work of the bag filter 3 is timely. In this case, the operation of the dust collecting tower is stopped (for continuous operation, the dust collecting towers are installed in parallel, and the operation is switched to a separate dust collecting tower). The bag filter 3 is pulled out upward from the upper suction chamber 4. In this work, the cage retainer previously inserted into each bag filter 3 is pulled out, the dust collecting hose 20 from the dust collector 19 is brought into contact with the inside of the bag filter 3, and the hose port 20a is operated by operating the dust collector 19. Therefore, the soot, dust, and the like adhering to the inner and outer peripheral edges of the bag filter 3 are sucked and removed. This may be performed simultaneously in the process of pulling out the bag filters upward.

Then, the bag filter 3 taken out upward is attached to the mouth portion of the retaining metal fitting 10a of the support rod 10 of the flexible hose 9, and when it is attached, the hand operation switch 16 is turned on. Drives the electric motor 12 to rotate the take-up reel 11. As a result, the bag filter 3 moves in the flexible hose 9 toward the inside of the box body 7, and when its mouth end projects in the box body 7 as shown in FIG. Therefore, in this state, the mouth end is hooked on the hook 14 on the disk 13b of the bag filter winding means 13 installed in the box body 2, and then the winding means is stopped. The drive of (1) causes the bag filter 3 to be spirally wound around the shaft 13a of the disc 13b.

Soot, dust and the like generated in the box body 7 due to the above-mentioned winding operation are sucked to the dust collector 19 side through the hose 21 which opens into the box body 7. Those that fall without being sucked are stored in the lower drawer 17 and taken out to the outside in a timely manner.

By the way, the bag filter 3 wound around the rotary shaft 13a of the disk 13b has its locking string hooked to the hook 1.
4 and is taken out of the box body 7 and FIG. 3 is a perspective view thereof. Then, this can be directly stored in a predetermined corrugated cardboard box and directly transferred to an incinerator or the like, so that efficient work can be performed. In addition, the strut 10 that has locked the bag filter 3 and transported in the bending hose 9 is the take-up reel 1 on the tip end side of the bending hose 9.
By rotating 5 with the manual handle 15a, it is rewound to the initial position to prepare for the replacement work of the next bag filter.

When the height of the dust collecting tower 1 is high due to the bag filter replacement work described above, it is necessary to hold the flexible hose 9 at an appropriate height. In this case, however, it is appropriate. It is advisable to use the crane 22 to suspend and hold the flexible hose 9.

[0017]

EFFECTS OF THE INVENTION The present invention is constructed as described above. As in the conventional one, a used bag filter is dropped into the dust collecting tower, and the bag filter is dropped from the lower manhole (cleaning port) to the floor surface. It is possible to eliminate the complicated and unsanitary human work of taking out and folding or winding up, that is, according to the present invention, it is possible to take in the device of the box main body through the bending hose. Since it is automatically wound in a spiral shape, all the soot and dust generated during the work will not be released to the outside, and the whole work will be easy and extremely hygienic from the beginning to the end. It does not give rise to any cause.
