[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector for collecting lint dust generated in a dryer at a cleaning factory for clothes, buns and the like.

[0002]

2. Description of the Related Art Cotton, fibers, thread waste, and lint dust such as human hair and paper dust generated in a dryer at a cleaning factory for clothes, buns, etc. are filtered and removed by a filter cloth cylinder. Since the conventional filter cloth cylinder is fixed on the outer circumference of the mounting cylinder as shown in the figure, lint dust that falls because the mounting cylinder projects into the lower end of the filter cloth cylinder is locked on the mounting cylinder. Accumulated,
The dust collector may not fall into the dust collector, resulting in poor dust collection efficiency.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention provides a dust collector that can reliably drop lint dust that has been filtered and remains in the filter cloth cylinder into the dust collector.

[0004]

For this reason, the present invention has
The lint dust is collected by filtering air from a dryer that contains lint dust such as fibers and lint with a filter cloth. A lint dust-containing gas supply duct is installed on the upper part and a dust collector is installed on the lower part. In the case where the filter cloth cylinder is installed between the supply duct and the dust collector, the attachment cylinder is fixed downward on the lower surface around the hole of the filter residue drop hole of the partition plate installed inside the machine body, The filter cloth cylinder having the upper end fixed at the upper part is passed through the filter drip drop hole of the partition plate, the entire lower end thereof is folded back to the outer periphery of the mounting cylinder, and the folded portion is crimped and held to the mounting cylinder by a tightening band. The filter cloth cylinder having the shape in which the bottom opening becomes wider as it goes downward is optimal for the natural fall of lint dust.

[0005]

[Function] Since the filter cloth cylinder is passed through the filter slag drop hole of the partition plate and the entire lower end thereof is folded back and attached to the outer circumference of the mounting cylinder, the filter cloth cylinder is arranged inside and the mounting cylinder is located outside, so that the lint The dust naturally falls down without being caught by the obstacle. Further, since the folded-back portion at the lower end of the filter cloth cylinder is pressed and held to the mounting cylinder with the tightening band, the filter cloth cylinder can be securely fixed without coming off.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiments of the present invention will be described below. In the present example shown in FIG. 1, reference numeral 1 is a box-shaped body, and a mounting piece 11 is horizontally fixed to an upper part of the inside thereof,
A mounting cylinder 13 is fixed around the dust-containing gas passage hole 12 of the mounting piece 11. Further, the partition plate 14 is horizontally fixed to the lower portion inside the machine body 1, and a mounting cylinder 16 is provided so as to project downward on the lower surface around the filter slag drop hole 15 of the partition plate 14.

The upper end of the filter cloth cylinder 2 is fastened and fixed to the outer periphery of the mounting cylinder 13 of the mounting piece 11 with the tightening band 3, and the lower end of the filter cloth cylinder 2 is attached to the filter residue drop hole 15 of the partition plate 14.
After passing through the inside, as shown in FIG. 2, it is folded back to the outer periphery of the mounting tube 16 and crimped to the mounting tube 16 with the tightening band 4 to hold the filter cloth tube 2 in tension.

The lower end of the mounting cylinder 16 is rolled outwardly and swelled to prevent the tightening band 4 from falling and prevent the filter cloth cylinder 2 from coming off. Further, the filter cloth cylinder 2 is a mesh of 150 mesh, and has a shape in which the bottom opening becomes wider as it goes downward.

Reference numeral 51 denotes a supply duct for taking in the lint-containing dust-containing gas from the dryer, which is connected to the distribution pipe 5 which communicates with the dust-containing gas passage hole 12 of the upper mounting piece 11 in the machine body 1.
In addition, below the lower partition plate 14 in the machine body 1, the filter residue drop hole 1
A lint box 6 for receiving the sludge falling from 5 is arranged so that it can be pulled out by a rail. Further, an exhaust port 17 is provided in the inner peripheral portion of the machine body 1 corresponding to the position of the lower part of the filter cloth cylinder 2.

Since this embodiment is constructed in this way, the lint-containing dust gas from the dryer is supplied from the distribution pipe 5 into the filter cloth cylinder 2 through the supply duct 51 and filtered, and the clean gas passes through the filter cloth. It is exhausted from the exhaust port 17. On the other hand, lint dust adheres to and remains on the inner peripheral surface of the filter cloth cylinder 2, and when it becomes thick, the lint dust naturally falls on the lint box 6 by its own weight.

According to this embodiment, the entire lower end of the filter cloth cylinder 2 is folded back and attached to the outer circumference of the mounting cylinder 16.
Since l is disposed inside, the lint dust naturally falls without being locked to the projecting member such as the mounting cylinder 16. Also,
Filter cloth cylinder 2 Attach the folded part at the lower end with the tightening band 4
Since the filter cloth cylinder 2 is stretched and held on the nozzle 6, the filter cloth cylinder 2 can be securely fixed without coming off.

Further, in this embodiment, since the filter cloth cylinder 2 is expanded downwardly, the filter portion is inclined, and the lint-containing gas from above is smoothly discharged from the inclined surface. In addition to being able to filter, the filter cake attached to the filter cloth tube 2 is easily separated by the downward flow of the gas, so that the filter cake can be dropped quickly and clogging can be reduced.

Although this example is constructed as described above, the present invention is not limited to this. For example, the shape of the partition plate having the filter drop hole, the shape of the mounting cylinder attached to the partition plate, and the mounting configuration may be as shown in FIG. Further, the shape and material of the filter cloth cylinder are not limited. Furthermore, the material and structure of the tightening band are also appropriate. The exhaust port and the dust collector may have arbitrary configurations, and may be configured as shown in FIG. Further, a large number of filter cloth cylinders may be provided in the machine.

[0014]

According to the present invention, since the entire lower end of the filter cloth cylinder is folded over and attached to the outer circumference of the mounting cylinder, the filter cloth cylinder is disposed inside, and lint dust is locked and accumulated on the protruding member such as the mounting cylinder. Without falling, it falls naturally and maintains a good filtering action. Further, in claim 2, the filtering portion is inclined,
Since the lint-containing dust gas from above escapes in a downward inclined flow, the filter cake attached to the filter cloth is easily separated and can be dropped quickly, clogging can be reduced, and good filtering action can be achieved. Of.
