[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector capable of removing dust from a cassette filter during operation.

[0002]

2. Description of the Related Art According to the invention of Japanese Utility Model Publication No. 3-9786, a cassette filter having a number of bag-shaped filters arranged in a line is provided inside a dust collector body, an endless belt running close to the cassette filter is provided, and a cassette filter is provided. A dust removing device is provided in which a pressure contactor for hitting is projected on an endless belt in the form of a knob.

It is a well-known technique to provide a bucket chamber at the bottom of a dust collector and detachably mount a bucket for containing dust.

[0004]

In the dust collector according to the invention described above, when the dust removing device is driven during the dust collecting operation and the cassette filter is hit with a pressure contact, fine dust released from the cassette filter is generated in the cassette filter. A motor that drives the blower through the cassette filter because it is under negative pressure and vibrates.
The motor may be sucked into the motor and burn out. Therefore, when driving the dust removing device, it is necessary to stop the operation of the blower, and continuous operation cannot be performed.

[0005]

SUMMARY OF THE INVENTION A dust collector is provided with a dust removing device in which a pressure contact for hitting a cassette filter is protruded in a nodular shape on an endless belt running close to a cassette filter in which a number of bag-shaped filters are arranged. And a bucket for accommodating dust is removably mounted in a bucket chamber provided below the cassette filter, a suction port is provided on one side of the dust collector body, and two cassette filters are provided on each side. Is provided from the other side of the dust collector main body, an air inlet is opened on both upper side surfaces of the dust collector main body above the exposed cassette filter, and an openable / closable and dust removing device for closing the air inlet is operated. Shutters are provided on the upper surface of the main body of the dust collector so as to form a negative pressure chamber above the bucket chamber, and cover the cassette filter and the air inlet with a lid. By providing a duct communicating with the chamber, incorporating a blower, and providing a blower chamber with an air discharge port at the top of the negative pressure chamber and communicating with the negative pressure chamber, dust collection and cassettes can be performed during operation of the blower. It is an object of the present invention to simultaneously remove dust from a filter to enable continuous operation of a blower.

[0006]

As shown in FIG. 2A, both shutters are opened and the blower is driven to suck dust from the suction port into the negative pressure chamber.
Large dust is stored in a bucket room, fine dust is collected by a cassette filter, and clean air is radiated from the air discharge port of the blower room to the outside through a duct.

As shown in FIGS. 2B and 2C,
When one of the right and left shutters is closed and the blower is driven to suck dust from the suction port into the negative pressure chamber, the dust dropping device on the side where the shutter is closed also operates in conjunction with the shutter closing motion, and the cassette filter is hit with a pressure contact. Although dust is dropped, large pressure dust falls into the bucket by its own weight due to the negative pressure inside the cassette filter, and a part of the loose fine dust is released on the side where the shutter is released again. And clean air is released from the air outlet of the blower room to the outside of the machine.

FIG. 1 is a perspective view showing the appearance of the present invention, and FIGS. 2 (a), 2 (b) and 2 (c) are explanatory views showing an operation method.
FIG. 3 is a perspective view of the shutter, and FIG. 4 is a front view showing the dust removing device and the cassette filter.

A dust removing device 4 in which a pressure contactor 3 for hitting the cassette filter 1 is projected in a nodular shape on an endless belt 2 running close to the cassette filter 1 in which a number of bag-shaped filters 1a are arranged. In the dust collector, which is provided at the center of the dust collector 5 and detachably mounts a bucket 6a for accommodating dust from a lower side of the dust collector main body 5 to a bucket chamber 6 provided below the cassette filter 1, the suction is sucked into one side surface of the dust collector main body 5. An opening 7 is provided, and two sets of left and right cassette filters 1 are provided with their outsides exposed from the other side surface of the dust collector main body 5. The air inlet 8 is opened, and an openable and closable shutter 9 for closing the air inlet 8 is provided on the upper surface 5a of the main body 5 of the dust collector. To form a chamber 10. The shutter 9 has a similar horizontally long rectangular shape slightly smaller than the air inlet 8,
A front plate 9a having an arcuate outer surface, and fan-shaped side plates 9b are fixed at right angles to both ends of the front plate 9a, and a bracket 9c is erected on the upper surface 5a of the dust collector main body 5 to form a lower end of the side plate 9b. And a motor 1 on the upper surface 5a of the dust collector body 5.
1, a pulley 11b is fixed to the motor drive shaft 11a, and the eccentric position of the pulley 11b and the side plate 9b of the shutter 9 are provided.
Of the shutter 9 by connecting the crank rod 11c
Open and close.

A duct 12 communicating with the negative pressure chamber 10 is formed by covering the cassette filter 1 and the air inlet 8 with a lid,
A soundproof blower chamber 14 having a built-in blower 13 and having an air discharge port 14a is provided above the negative pressure chamber 10 so as to communicate with the negative pressure chamber 10.

[0011]

[Effect of the Invention] The blower 13 is driven, and both shutters 9 are driven.
Is released and dust is sucked into the negative pressure chamber 10 from the suction port 7, large dust falls into the bucket 6a by its own weight, and fine dust is collected by the bag-shaped filter 1a of the cassette filter 1 and cleaned. The air passes through the duct 12, passes through the air inlet 8, and diffuses from the air discharge port 14 a of the blower chamber 14 into the atmosphere.

When one of the shutters 9 is closed and the dust removing device 4 provided on the side of the cassette filter 1 communicating with the closed duct 12 is driven, fine dust clogged in each filter 1a is released, and the dust is removed. The air that has been collected and cleaned by the other cassette filter 1 that is not operating and passes through the duct 12 passes through the air inlet 8, and then diffuses into the atmosphere from the air discharge port 14a of the blower chamber 14.

Therefore, the dust removal device 4 is driven in the dust collector main body 5 while driving the blower 13 and sucking dust, so that the dust collection and dust removal can be performed at the same time, thereby significantly improving the work efficiency.
