Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cartridge filter mounting mechanism for mounting a cartridge filter on a cell plate.
[0002]
[Prior art]
Conventionally, in a bag filter type dust collector, the cartridge filter is suspended from the mounting hole of the cell plate and fastened to the cell plate with several bolts or tightened like a clip band. Attached to the retainer with a bracket. However, fixing with bolts or clip bands is a troublesome manual work, and there is a problem that it takes a long time to attach and detach the cartridge filter.
[0003]
Therefore, the applicant of the present application has a cartridge filter body, which is formed of a synthetic resin having elasticity and has an upper edge integrally provided with a cylindrical body on the upper edge, and has the flange portion in the hole portion of the cell plate. A tubular retainer with a hook provided with a bulging portion having an outer diameter larger than the inner diameter of the tubular body is fitted into the tubular body, and the tubular body is expanded outward by the bulging portion, so that the hole in the cell plate A cartridge filter mounting mechanism has been proposed in which a cartridge filter is mounted on a cell plate in close contact with a portion (Japanese Patent Laid-Open No. 2001-269527).
[0004]
[Problems to be solved by the invention]
However, as shown in FIG. 2, the cartridge filter 11 is attached to the upper portion of the filter 11A so that the cartridge 13 is attached to the hole 12A of the cell plate 12 when the cartridge filter 11 is mounted. It consists of a first step of fitting and inserting the flange portion 13A into the cell plate 12 and then a second step of fitting the retainer 14 into the cylindrical body 13. Therefore, although improved, there is a problem that it takes some time to attach and detach the cartridge filter.
[0005]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a cartridge filter mounting mechanism that can more efficiently attach and detach the cartridge filter with one touch. To do.
[0006]
[Means for solving the problems]
In order to achieve the above-described object, the cartridge filter mounting mechanism according to the present invention is formed by integrally fixing a thin cylindrical joint on the outer surface to the lower part of a vent hole of a cell plate fixed horizontally in a dust collector. On the other hand, in a cartridge filter in which a cylindrical body made of a synthetic resin and having elasticity is fixed to an upper end of a cylindrical filter supported so as to be movable up and down, an inner hole surface of the cylindrical body is parallel to an outer surface inclination of the cylindrical joint. And is configured to be slightly smaller than the outer surface of the tubular joint.
[0007]
In the present invention, a plurality of convex band rings are integrally formed on the inner hole surface of the cylindrical body.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the embodiment of the present invention will be described in detail with reference to FIG. FIG. 1 shows a cartridge filter attached to a cell plate in a bag filter type dust collector.
A cell plate 2 for attaching / detaching the cartridge filter 1 is fixed horizontally in a dust collector (not shown), and a large number (only one is displayed in FIG. 1) of the cell plate 2 is vented. A hole 3 is opened, and a lower thin tubular joint 4 is integrally fixed to the lower part of the vent hole 3.
[0009]
On the other hand, in the cartridge filter 1, a cylindrical body 1B made of a synthetic resin and having elasticity is fixed to the upper end of the cylindrical filter 1A. The cylindrical body 1B has an inner hole surface 1C inclined on the outer surface of the cylindrical joint 4. And is parallel.
Further, two convex band rings 1D, 1E spaced vertically are integrally formed on the inner hole surface of the cylindrical body 1B, and the inner peripheral surface thereof is slightly smaller than the corresponding outer surface of the cylindrical joint 4. It is configured.
[0010]
In order to mount the cartridge filter 1 in which the cylindrical body 1B is fixed to the upper end of the cylindrical filter 1A on the cell plate 2 provided with the lower narrow cylindrical joint 4, After the inverted conical inner hole of the cylindrical body 1B of the cartridge filter 1 is made to face the cylindrical joint 4 of the cell plate 2, the entire cartridge filter 1 is passed through a filter support (not shown). Raise and hold the state.
[0011]
At this time, the cylindrical joint 4 is relatively inserted into the inner hole of the cylindrical body 1B, the cylindrical joint 4 is brought into contact with the convex ring 1D, 1E, and the inner hole of the cylindrical body 1B is further pushed open. As shown in FIG. 1, both of them are inserted and mounted so as to be in a tight clamp state.
When the cartridge filter 1 is removed from the cell plate 2, it can be easily separated and removed simply by removing the clamp of the filter support (not shown) and pulling the tubular body 1B out of the tubular joint 4.
[0012]
Although the cylindrical body 1B is made of a synthetic resin having elasticity, urethane resin is suitable for this, but the material is not limited. The cylindrical body 1 </ b> B may have any outer peripheral shape as long as the inner hole surface 1 </ b> C is parallel to the inclined outer surface of the cylindrical joint 4 (that is, a bowl shape).
Furthermore, the convex ring 1D and 1E on the inner hole surface of the cylinder 1B may be deleted, and only the inner hole surface 1C may be used. In this case, the outer surface of the tubular joint 4 and the inner hole surface 1C of the tubular body 1B are brought into contact with each other so as to push the tubular body 1B open.
[0013]
【The invention's effect】
As is apparent from the above description, the cartridge filter mounting mechanism of the present invention is formed by integrating a cylindrical joint with a lower outer surface integrally with a lower portion of a vent hole of a cell plate fixed horizontally in a dust collector. In a cartridge filter in which a cylindrical body made of a synthetic resin is fixed to the upper end of a cylindrical filter supported so as to be movable up and down, the inner hole surface of the cylindrical body is inclined to the outer surface of the cylindrical joint. The cartridge filter can be easily and securely attached to the cell plate with a single touch, making it easy to attach and remove the cartridge filter. There is a tremendous contribution to the development of the industry, such as being able to do well.
