Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary tool used when mounting a bag in a bag filter.

[0002]

2. Description of the Related Art A bag filter is constructed by suspending a large number of long cylindrical bag-shaped bags from the ceiling in a casing, passing dust-containing gas through the filter cloth of the bag, and capturing dust on the inner surface of the filter cloth. It is a gathering. In the bug filter, it is necessary to replace the bug. The work of attaching the bug to the bag filter is necessary when the bag filter is newly installed or when the damaged filter cloth is removed and replaced with a new one. This work is done manually.

FIG. 3 is an explanatory diagram showing a bug filter. 3 (a) is a side view of the bag filter, and FIG. 3 (b) is a vertical cross-sectional view in a direction perpendicular to FIG. 3 (a). A large number of bugs 10 are suspended in the bag filter 20, and when the gas introduced from the dust-containing gas inlet 21 passes from the inner surface to the outer surface of the bag 10, dust is collected by the bag and the exhaust pipe is exhausted. It is discharged from 22. The switching valve 23 controls the passage path of gas. The bug that gas does not pass is
The bag is vibrated to drop dust downwards. This dust is collected in the dust discharge pipe 24 and discharged from the discharge port 25. The bag 10 has a cap 11 attached to the upper end of a tubular body made of, for example, woven nylon fiber, and is suspended from the ceiling of the bag filter 20 by a suspending metal 13. As shown in FIG. 3C, the cap 11 is provided with a hook 17. The bottom plate 26 of the bag filter is perforated and has a bag mounting cylinder 16 attached thereto. FIG. 3D is a perspective view thereof. The lower end of the bag 10 is fitted onto the bag mounting cylinder 16 and its outer diameter is fixed by a band 15.

To attach the bag 10 to the bag filter 20, the hook 17 is hung on the hanging metal fitting 13 and the cap 1 is attached.
1 is suspended, the lowermost end of the bag is fitted over the outer circumference of the cylinder 16, and the band 15 is hung on the outer circumference to fix the bug. Bug 1 to scavenge the dust inside Bug 10
0 is vibrated, but a spring 14 is provided between the cap 11 of the bag and its hanging fitting 13 in order to efficiently remove dust due to this vibration and prevent the bag 10 from loosening after mounting. There is an intervening bug (Fig. 2).
Since such a bug is pulled upward by a spring, if you pull it down to fit the lower end of the bug onto a cylinder and put a band on it, the bug is unstable and easy to move. It is difficult to do in and requires multiple manpower.

It is an object of the present invention to provide a tool which eliminates this drawback and allows one person to carry out the mounting operation.

SUMMARY OF THE INVENTION According to the present invention, an upper rod having hooks for hooking the upper and side surfaces of a cap at the upper end of a bug and an L for engaging with a lower edge of a cylinder for attaching the lower end of an adjacent bag. It is composed of a lower bar having a bend at the lower end and a rope connecting the upper bar and the lower bar, and the length between the upper end of the upper bar and the lower end of the lower bar is approximately equal to the length of the hanging bag. It is a bug mounting tool for a bug filter.

[0007]

The bag mounting tool of the present invention is used when a bag having a cap made of metal or the like mounted on the top end of the bag is hung from the ceiling of the bag filter via a spring and the lower end of the bag is mounted on the bottom plate of the bag filter. To use. In the past, there was no such tool. The upper rod is a rod-shaped rigid metal fitting having a hook at the upper end, and this hook is hooked on the upper surface and the side surface of the bag cap hung at a predetermined position of the bag filter. The lower bar is a rigid bar having an L-shaped bend at the lower end. This L-shaped bend locks on the lower edge of the lower end mounting cylinder of a bug which has not been mounted next to or near the mounting target bug. In this way, the position of the cap is lowered, the lower end of the bag is covered with the outer diameter of the lower end mounting cylinder, and the outer diameter is fixed with the band. Although it takes two to three people to fix the lower end of the bug while pulling the bug down by human power, one person can easily carry out the installation using the bug attaching tool of the present invention.

The total length of the bag attachment tool is set to a length required for pulling down the cap and fitting the lower end of the bag into the lower end attachment cylinder. While the bug is stable, attach the band to the outer diameter of the bottom of the bug to complete the bug installation work. The upper bar and the lower bar are connected by a rope. The rope has a function of allowing the upper bar and the lower bar to rotate relative to each other, and can absorb the twist about the central axis in the length direction of the bug attachment. Also, the length of the rope can be adjusted to adjust the total length of the bag attachment.

1 is a perspective view showing a bag mounting tool 1 according to an embodiment of the present invention, and FIG. 2 is an explanatory view of its usage state. The bag attachment 1 comprises an upper rod 2, a lower rod 3 and a rope 4 connecting the upper rod and the lower rod. Upper bar 2
Consists of a rigid elongated bar with a hook at the top that hooks into the bag cap. In the example shown in FIG. 1A, the hook 5
Consists of two parallel hooks with claws attached to the tip,
In the example shown in (b), the hook 6 has two V
It consists of a character hook. The claw abuts on the side surface of the bag cap, and the hook sticks on the upper surface of the cap so that the hook hooks on the cap. Both types of hooks can be reliably fixed in position by abutting the cap on the upper surface of the cap with a hook at the center interposed therebetween.

The lower bar 3 is made of a rigid elongated round bar, and has an L-shaped bend 8 at its lower end. The L-shaped bend 8 is locked to the lower edge of the bag mounting cylinder 16 on the bottom plate of the bag filter. The upper rod 2 and the lower rod 3 are connected by a rope 4. The upper bar 2 has a ring 7 at its lower end and the lower bar 3 has a ring 9 at its upper end. The rope 4 tightly binds one end of each of the rings 7 and 9. The length of the bug attachment 1 is adjusted by the rope 4. The rope 4 is a member that can absorb a twist about the central axis in the length direction, and the hooks 5 or 6 and the L-shaped bend 8 can be oriented in arbitrary directions.

FIG. 2 is an explanatory view showing a usage state of the bug attaching tool 1 of the embodiment. In FIG. 2, a bug 10a shows a state during the bug attaching work, and a bug 10b shows a state after the attaching is completed. There is. The bug 10a is hung from the hanging metal fitting 13 on the ceiling of the bag filter via the spring 14, and the hook 11 at the upper end of the bug attaching tool 1 is hooked on the cap 11 at the upper end of the bug 10a. The L-shaped bend 8 at the lower end is locked to the lower edge of the adjacent bug lower end mounting cylinder 16. That is, the bug attaching tool 1 pulls the bug 10a downward, and the lower end 12 of the bug 10a is fitted onto the outer diameter of the bug lower end attaching cylinder 16. Therefore, the lower end of the bag 10a can be easily fixed by the stop band 15. Bug 1
0b shows a state in which this work is completed and the bug attaching tool 1 is removed. The bug 10b is tensioned up and down by the urging force of the spring 14, and the dust removal is kept in an effective state.

The labor saving effect of the embodiment is particularly remarkable in the bag filter with the spring. It is also useful because it is possible to perform work reliably in a short time when many bugs are installed.

[0013]

EFFECT OF THE INVENTION By using the bag mounting tool of the present invention, the work of mounting the bug on the bag filter can be stably and reliably carried out. Also, the number of personnel required for the work can be reduced.
