Abstract

PROBLEM TO BE SOLVED: To make it possible to surely recover only the heavy dust within a dust box by simple constitution and to comprehensively and efficiently collect the lightweight dust at the various points in a factory by annihilating the inertia force of the heavy dust. SOLUTION: This comprehensive dust collector is provided with branch pipes 2 which are branched from a main pipe 1 connected to a suction pump, draft side openings 4 which are inserted with dust boxes 3 between the branch pipes and dust collecting ducts 6 and communicate with the branch pipes 2 in the dust boxes 3 and collision plates 8 interposed in the gas passages between the suction side openings 4 communicating with the dust collecting ducts 6. The baffle plates 8 are formed of perpendicular plates which bisect the upper parts of the dust boxes 3 to the right and left.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general dust collecting apparatus, and more particularly to a general dust collecting apparatus capable of effectively recovering heavy dust.

[0002]

2. Description of the Related Art Conventionally, an integrated dust collection system for processing dust in various places in a large factory is described in, for example, Japanese Utility Model Registration No. 2548560.

[0003] In such a system, a main pipe connected to a suction pump is arranged at a required location in a factory, branch pipes are extended from the main pipe to a plurality of locations in the factory, and the upper part of a dust box is attached to the branch pipe. Connected to a side wall of the dust box, a flexible dust collecting hose having a diameter smaller than that of the branch pipe is detachably connected, and heavy dust sucked by the dust collecting hose is dropped and collected by decreasing the negative pressure of the dust box. The system is designed to collect and collect lightweight dust from each dust box via the main pipe.

[0004]

However, in the prior art described above, the suction side opening for the branch pipe is made larger in diameter than the suction side opening for the dust collection hose, and a negative pressure is reduced in the dust box. There is a drawback that heavy dust cannot be sufficiently collected because the inertia force of the ignoring force is ignored.

That is, the present inventor has conducted various experiments and studies,
Even if the suction side opening of the dust box is made larger in diameter than the suction side opening as in the above-described conventional one, the negative pressure reduction generated in the dust box is extremely small, and the amount of air entering the dust box through the suction side opening and the dust box Since the amount of air exiting from the suction side opening of the dust box is eventually the same, heavy dust entering the dust box from the suction side opening of the dust box enters the suction side opening as it is due to its inertia force, and the amount of falling in the dust box is extremely small. Was.

The present invention eliminates the above-mentioned disadvantages by eliminating the inertial force of such heavy dust.

[0007]

According to the present invention, there is provided an integrated dust collecting apparatus comprising: a main pipe connected to a suction pump; a branch pipe branched from the main pipe; a dust collecting duct; A dust box inserted between the dust collection duct, and the dust box is inserted into a gas passage between a suction side opening communicating with the branch pipe and a suction side opening communicating with the dust collection duct. It has a collision plate.

The collision plate is a vertical plate that divides the upper portion of the dust box into two right and left parts.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a main pipe connected to a suction pump (not shown), 2 is a branch pipe branched from the main pipe 1, 3 is a dust box, and 4 is connected to the branch pipe 2. A suction side opening of the dust box 3,
5 is a suction side opening of the dust box 3, 6 is a dust collection duct connected to the suction side opening 5, and 7 is this dust collection duct 6.
In the present invention, a collision plate 8 is provided in the dust box 3 so as to be inserted into a gas flow path between the suction side opening 4 and the suction side opening 5 in the present invention.

In FIG. 1, the suction side opening 4 and the suction side opening 5 are arranged at substantially the same level on both side surfaces of the dust box 3, respectively. In this case, as shown in FIG. Is vertically arranged at the center upper part of the dust box 3 so as to divide the upper part of the dust box 3 into two right and left parts.

Since the integrated dust collecting apparatus of the present invention is configured as described above, the dust flowing into the dust box 3 from the suction side opening 5 hits the collision plate 8, passes through the lower side thereof, and enters the suction side opening 4. As a result, heavy dust loses its inertia when colliding with the collision plate 8, falls down along the vertical collision plate 8 to the bottom of the dust box 3, and only lightweight dust reaches the suction side opening 4. Become.

When the suction side opening 4 is at a different level from the suction side opening 5, or when the suction side opening 4 is provided at the top of the dust box 3, the collision plate 8 is preferably disposed obliquely.

[0014]

As described above, according to the integrated dust collecting apparatus of the present invention, the suction side opening 4 of the dust box 3 is changed to the suction side opening 5.
With a larger diameter, there is no need to cause a decrease in negative pressure in the dust box 3, and only the heavy dust can be reliably collected in the dust box 3 with an extremely simple configuration, and the light dust in various parts of the factory can be collected efficiently and efficiently. There are great benefits to be able to.
