BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter bag retainer for supporting a filter bag of a dust collector from the inside, which is of a split type and has excellent handleability.

[0002]

2. Description of the Related Art Conventionally, as a retainer for a filter bag, for example, an iron wire having a diameter of 3 to 5 mm is used as a vertical wire of 8 to
Twenty-four pieces, which are arranged in a tubular shape at regular intervals and are held inside by a horizontal fixing ring made of the same iron wire, are widely used. These are loaded into the machine from the top of the dust collector for use. It was Such a filter bag retainer usually has a length of 5 to 7 depending on the length of the filter bag.
Since it is a long m, it is not easy to handle. Especially when the dust collector becomes large and the distance to the ceiling of the building becomes shorter as recently, the loading and unloading work of the retainer for the filter bag is difficult. The problem was that it would be difficult. Therefore, as disclosed in Japanese Utility Model Laid-Open No. 4-106617, a large number of vertical lines formed in an inward taper rod portion with a recess for ring engagement formed in the base at one end of the straight rod portion are formed into a cylindrical basket shape. A fixing ring for engaging the recess is provided in the straight rod part of the vertical line behind the recess and the connecting end of both split retainers are inserted to divide the recess of each split retainer into the other side. A retainer for a filter bag has been proposed in which a retainer body is assembled by engaging with a fixing ring of the retainer.

However, in the split type filter bag retainer composed of the split retainers described above, the recesses formed at the tips of the connecting ends of the split retainers are integrally engaged with the fixing rings provided in the split retainers. Since the dimensional accuracy is required, in order to integrate them, it is necessary to insert them by a strong pushing force of both, and the strong pushing force makes assembly and division work difficult. In addition, if the size of the fixing ring and the recess is made to have a margin in order to weaken the pushing force, there is a problem that sufficient holding force cannot be secured even if the assembling and dividing operations are facilitated.

[0004]

The problem to be solved by the present invention is to solve the above-mentioned conventional problems and to improve the handleability of loading and unloading operations of a dust collector by a division type. The filter bag retainer is excellent, and even if there is a dimensional error, the force required for disassembling and connecting the retainer is extremely small, and it can be assembled manually without using a special tool, and a sufficient holding force can be secured. Is to try to provide.

[0005]

The retainer for a filter bag according to the present invention, which has been made to solve the above-mentioned problems, has an inward taper in which one end of the straight rod is formed with a recess for ring engagement at the base. A plurality of vertical lines formed on the rod portion are connected in a cylindrical basket shape, and the connecting ends of the split retainers, which are provided with a ring for engaging the recessed portion, are inserted in the straight rod portion of the vertical line behind the recessed portion. In a retainer for a filter bag, in which the recesses of the split retainers are engaged with the rings of the split retainers on the opposite side to assemble the retainer body, the lower split of the rings provided on the upper and lower split retainers is used. The retainer ring is a fixed ring fixed to the straight rod of the vertical line, while the upper split retainer ring is guided by a vertically long ring guide provided at the tip of the vertical line. It is characterized in that it has a downward freely moving ring. In addition, in such a retainer for a filter bag, a vertically long ring guide is formed by folding back a tip portion of a part of a vertical line to enhance productivity, and it is an invention of claim 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a retainer main body in which connecting end portions of cylindrical cage-like split retainers 11 and 12 are inserted and connected to each other. The retainer main body 1 has a filter bag mounted on the outer surface thereof and is set in a dust collector. It is basically the same as the conventional retainer for a filter bag of this type. Split retainer 1
1 and 12 are common in that twelve vertical lines 12 and 22 each made of a steel wire having a diameter of 3.2 mm are arranged in a tubular shape and all the vertical lines 12 are welded and fixed by a connecting ring. , One of the split retainers 11 on the upper side is an inward direction in which every other one of the vertical lines 12 on the connecting side is provided with a recessed portion 14 for ring engagement at the base portion of every six tips. Is formed on the taper rod portion 13 of the above, and the remaining six tip portions are formed on a vertically elongated ring guide 17 folded back so as to be shorter than the vertical line on which the taper rod portion 13 is formed. A movable ring 15 for engaging the recess is guided by the guide 17 so as to be vertically movable. It is preferable that the ring guide 17 has a width such that the moving ring 15 does not drop due to frictional resistance due to gravity alone. In addition, the other split retainer vertical line 22 on the lower side of the split retainers 11 and 12 also has the vertical line 2 on the connecting side thereof.
One of the above two divisions in that every other six tip portions, which are a part of the two, are formed in an inward taper rod portion 23 having a recess 24 for ring engagement in the rear portion. It is similar to the retainer 11, but the remaining six tip portions are formed on the taper rod portion 27 shorter than the vertical line on which the above-mentioned taper rod portion 23 is formed. A fixing ring 25 for engaging the recesses is welded and fixed to the inside of the straight rods of all the vertical lines 22 near the base, and thus, among the rings for engaging the recesses provided in both split retainers 11 and 21, The ring of the split retainer 21 on the lower side is a fixed ring 25, and the ring of the split retainer 11 on the upper side is folded back so as to be shorter than the vertical line 12 on which the tapered rod portion 13 is formed. Dressed in It is characterized in has been vertically movable guided structure of the connecting portion and moves the ring 15 was.

In the thus constructed structure, the split retainers 11 and 21 are separately manufactured in advance, and integrated into the retainer main body 1 at the site where they are attached to the dust collector, and then the filter retainer is covered by a conventional method. It is almost the same as the one using the conventional split retainer, but the assembly procedure is slightly different from the conventional one because the structure of the connecting portion is different.

That is, the retainer body 1 according to the present invention
As shown in FIG. 2, the procedure for assembling the first step is to push the split retainers 11, 21 up and down while keeping them vertically aligned with each other so that the connecting ends of the vertical lines 12, 22 do not face each other. , Upper split retainer 11
The recess 14 formed in the base of the taper rod 12 is engaged with the fixing ring 15 welded to the straight rod of the vertical line 22 of the lower split retainer 21. Subsequently, FIG.
As shown in FIG. 7, the moving ring 15 loaded in the vertically elongated ring guide 17 formed on the connection end side of the upper split retainer 11 is moved downward under the guide of the ring guide 17, Moving ring 15 split retainer 21
When the retainer main body 1 is assembled here by engaging with the recessed portion 24 formed in the base portion of the tapered rod portion 22, the filter bag may be covered thereafter by a conventional method. If the retainer body 1 is to be disassembled, the procedure may be reversed.

As described above, the retainer for a filter bag according to the present invention is a split type in which a plurality of split retainers 11 and 21 are joined to assemble the retainer main body 1. Therefore, the retainer is easily attached to the dust collector, and is transported and stored. Has a small space and exhibits excellent handleability. Further, the fixing ring 25 fixed to the lower split retainer 21 is provided.
On the other hand, after engaging the recessed portion 14 formed in the tapered rod portion 13 of the upper split retainer 11, the moving ring 15 in the ring guide 17 provided on the connection end side of the upper split retainer 11 is engaged. Is moved downward to engage with the recess 4b formed in the taper rod portion 23 of the lower split retainer 21, so that it can be manually connected or separated with a small force without using a special tool. You will be able to work.

The above description consists of 12 vertical lines.
Although the split-type filter bag retainer has been described, the number and the number of splits are not limited to this, and it goes without saying that the retainer can be arbitrarily designed as necessary.

[0011]

As is apparent from the above description, the present invention is of a split type and is excellent in handleability such as loading and unloading work for the dust collector, and moreover, the ring of the lower split retainer. While it is a fixed ring fixed to the vertical rod, the upper split retainer ring is a movable ring that can move up and down, so the pushing force and disassembling force for assembling the retainer body are extremely small. Although it can be easily assembled and disassembled by work, there is an advantage that a sufficient holding force can be secured. Therefore, the present invention, as a retainer for a filter bag that eliminates the conventional problems, has an extremely great contribution to the industrial development.
