Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filter cloth hanging metal fitting in a dust collector that can effectively prevent wear of a filter cloth held in a suspended state.

[0002]

[Prior Art]

 Conventionally, in a workplace where a large amount of dust is generated, such as in a foundry, the filter cloth is hooked at the upper end of the filter cloth by the hook-shaped hanging metal fittings to maintain a good working environment. Bag filter type dust collectors are widely used.

However, in the conventional bag filter type dust collector of this type, the hook-shaped hanging metal fitting for hooking the filter cloth is not used when it is in use due to the influence of moisture in the processing gas or other corrosive gases. There is a problem in that the surface of the filter cloth is rusted and the surface of the filter cloth is rugged, and particularly when the filter cloth attachment portion that holds the filter cloth is rusted, the roughened surface and the filter cloth rub against each other and the filter cloth is significantly worn and damaged. Therefore, recently, although anti-corrosion measures have been taken by applying heat-resistant plating etc. to the hanging metal fittings, sufficient effects cannot be obtained, and wear of the filter cloth can be effectively prevented by a simple and inexpensive means. Development of means was desired.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems, and can reliably prevent the filter cloth from being worn and damaged in the portion where the filter cloth is suspended and held, and the life of the filter cloth is significantly extended. In addition, the filter cloth replacement work can be reduced to improve the work efficiency, and the simple structure makes it cheap and excellent in economical efficiency. It has been completed for the purpose of providing

Means for Solving the Problems In the dust collector according to the present invention, which has been made to solve the above-mentioned problems, a filter cloth hanging metal fitting is a hook-shaped hanging metal fitting main body suspended from a shaking frame. The filter cloth attachment portion is covered with a cylindrical synthetic resin tube.

[0006]

[Action]

 In the present invention thus constructed, the filter cloth is suspended by the filter cloth attachment portion at the tip of the hook-shaped suspending metal body, similar to the filter cloth suspending metal in the conventional dust collector. However, since the surface of the filter cloth attachment part is closely covered with a cylindrical synthetic resin tube, the filter cloth will come into contact with the smooth synthetic resin tube and the friction between the two will occur. The filter cloth does not come into direct contact with the metal surface of the hanging metal fittings even if rust occurs on the filter cloth attachment part, so the rough surface and the filter cloth rub against each other and the filter cloth is worn and damaged. There is no need to do it.

[0007]

【Example】

 The present invention will now be described in detail with reference to the illustrated embodiment. In the figure, 1 is a shaking frame in the dust collector, 2 is a hook-shaped hanging metal fitting main body suspended from the shaking frame 1, 3 is a filter cloth mounting portion located at the tip of the hanging metal fitting main body, An envelope-shaped filter cloth 10 is hung on the filter cloth attachment portion 3 in a state of penetrating a hanging hole provided at the upper end thereof.

The filter cloth mounting portion 3 is covered with a cylindrical synthetic resin tube 4 which is sufficiently longer than the suspending hole portion of the filter cloth 10. The synthetic resin tube 4 is made of a synthetic resin such as nylon, Teflon, or silicon which has a smooth and slippery surface excellent in durability, abrasion resistance, heat resistance, etc. 3 is made up of a tubular tube having an inner diameter corresponding to the outer diameter of the filter cloth mounting portion 3 so as to fit closely to the outer peripheral surface of the filter cloth mounting portion 3, and the filter cloth mounting portion 3 is inserted into the tubular tube. By doing so, the synthetic resin tube 4 is brought into close contact with the outer peripheral surface.

With this structure, the filter cloth attaching portion 3 at the tip of the hook-shaped hanging metal fitting body 2 holds the filter cloth 10 in a suspended state, and the filter cloth in the conventional dust collecting apparatus of this type is used. Although it is similar to the cloth hanging metal fitting, since the outer surface of the filter cloth mounting portion 3 is covered with the cylindrical synthetic resin tube 4, the filter cloth 10 has the extremely smooth surface of the synthetic resin tube. As a result, the filter cloth 10 is smoothly moved on the synthetic resin tube 4 having a smooth surface even if the shaking frame 1 is violently rotated during the process of removing the filter cloth. It only vibrates, and wear damage due to friction hardly occurs. Even if rust is generated on the filter cloth mounting portion 3, since the filter cloth 10 is not in direct contact with the filter cloth mounting portion 3, the rough surface on which rust is generated and the filter cloth 10 are There is no need for the filter cloth to be rubbed against each other to cause severe wear and damage.

Moreover, since the cylindrical synthetic resin tube 4 covered by the filter cloth attachment portion 3 at the tip of the hanging metal fitting body 2 is seamless, it is like a tape made of synthetic resin tape of a certain width. The surface is extremely smooth without any step, and unlike the case of coating with synthetic resin powder, rust does not float and peel off, and a stable smooth surface can be maintained for a long period of time. Moreover, it is extremely easy to process and can be provided at low cost.

[0011]

[Effect of the device]

 As is clear from the above description, the present invention can reliably prevent the filter cloth from being worn and damaged in the portion where the filter cloth is suspended and held, and can prolong the life of the filter cloth significantly. In addition to being able to reduce the filter cloth replacement work, it is possible to improve the work efficiency, and it is also easy to manufacture with a simple structure and can exhibit excellent economic efficiency. It also has the advantage that it can be applied immediately without making any major changes to the hanging hardware of the type filter cloth. Therefore, the present invention has an extremely great practical value as a hanging member for a filter cloth in a dust collecting apparatus which has eliminated the conventional problems.
