[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated dust collection system using a dust box, and more particularly, to efficiently improve a work environment in a factory where a large amount of dust is generated, such as a casting factory, a welding factory, and various processing factories. It relates to an integrated dust collection system using a dust box.

[0002]

2. Description of the Related Art In the above foundries, welding plants, etc.,
Since dust such as sand and iron powder is generated, the dust is collected to improve the working environment. As this dust collection system,
Two measures have been taken to remove dust floating in the air and to treat dust that has fallen to the floor,
The former problem is solved by a method with a large suction duct or a fan.
Small vacuum cleaners and the like are used.

[0003] The present invention mainly relates to a system for treating dust on the floor, so that the dust will be treated in various places in a large factory when a conventional small vacuum cleaner is used. However, if a large number of vacuum cleaners are required and their suction power is not made relatively large, they cannot be used for removing industrial dust such as sand, iron powder, and granular materials. Therefore, if a relatively large number of vacuum cleaners are provided, the cost is high and the handling is troublesome.

[0004] In addition, since a small-sized vacuum cleaner discharges suction air immediately after suctioning dust, there is a problem that fine powder and the like that have passed through a filter still remain in a factory. Such airborne dust is discharged to the outside by a suction duct or fan provided on the factory wall, etc., but dust that floats and stays near the floor is completely sucked by such a remote suction duct or fan. It cannot be removed.

[0005]

In order to improve the effect of dust suction and removal at low cost, a main pump is provided instead of a plurality of small vacuum cleaners, and a main pipe or a hose is connected to the main pump. A system is conceivable in which the main pipe is arranged at a main location in a factory and dust is sucked through a plurality of branch pipes branched from the main pipe. However, since sand, iron particles or iron powder have high specific gravity and hardness, suctioning them requires a very large suction pump. In order to pass through and discharge to the outside, the inside of the pipe must be solid over its entire length, which requires the installation of hard chrome plating and ceramic plates, which makes the equipment expensive. In addition, there is a problem that operating costs are high.

In addition, large dust, human hair, paper debris and the like are liable to be clogged when moving in a long pipe, causing a problem that not only the suction efficiency is reduced but also a trouble occurs due to the clogging. An object of the present invention is to solve the problems of the related art and to provide a comprehensive dust collection system using a dust box that is low in cost, can prevent clogging, and has excellent suction efficiency.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art and to achieve the above object, the integrated dust collection system using a dust box according to the present invention includes a main pipe connected to a suction pump at a required location in a factory. And a branch pipe is extended from the main pipe at a plurality of places required for dust collection in the factory, and an upper part of a dust box is connected to the branch pipe. A flexible pipe having a smaller diameter than the branch pipe is provided on a side wall of the dust box. The dust collecting hose is detachably connected, the heavy dust sucked by the dust collecting hose is dropped and collected by decreasing the negative pressure of the dust box, and the lightweight dust is collectively collected from each dust box through the main pipe. Take the means to configure.

[0008] The suction pump referred to in the present invention refers to various types of pumps, such as a vane, a piston pump and a fan system, which are already known. The main pipe may be any pipe that has already been used, such as a steel pipe or a resin pipe.

[0009]

According to the present invention, since the centralized suction is performed by the central suction pump, the cost is lower than that of many conventional small vacuum cleaners, and the dust is sucked from the main pipe through the branch pipe. Branch pipes can be provided at appropriate places, and dust can be effectively collected at every corner of the factory. Then, by connecting the dust box to the branch pipe, large or heavy dust on the floor was negatively dropped in the dust box and stored here so as not to flow into the branch pipe or the main pipe. Not only can the branch pipe and the main pipe be prevented from clogging, but also the heavy pump does not need to be transported over a long distance, so that the suction pump can be downsized and the operating cost can be significantly reduced. Since fine dust can be discharged from the branch pipe through the main pipe to the outside (through a cleaner as appropriate), there is a problem that air containing fine dust sucked like a conventional small vacuum cleaner is discharged into the factory again. It can be eliminated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a preferred embodiment of an integrated dust collecting system using a dust box according to the present invention. As shown in FIGS. 1 to 3, a main pipe 15 connected to an appropriate suction pump (not shown) is disposed at a required location in the factory. In the factory, branch pipes 15 '... Are respectively extended from the main pipe 15 at a plurality of locations required for dust collection, and the dust pipes 2.
The upper part is connected. That is, the branch pipe 15 ′ is connected to the large-diameter suction port 5 above each dust box 2 via the valve 10 and the suction pipe joint 11.
On the upper side wall and the lower side wall of each of the dust boxes 2, small-diameter (compared to the suction port 5) suction sockets 4 and 4 'having openable lids 3 and 3' are provided.
It is configured such that a flexible dust collection hose 9 having a diameter smaller than 5 ′ can be detachably connected.

Accordingly, heavy dust sucked by the dust collection hose 9 around the portion requiring cleaning is dropped into the dust tank portion 1 below the dust box 2 due to a decrease in the negative pressure of the dust box 2, and is collected. The dust from each dust box 2 is collected and removed from the dust box 2 via the main pipe 15 via the branch pipe 15 '. The large or heavy dust in each dust tank unit 1 is removed from the dust box 2 and discarded separately.

In this embodiment, the dust is separated in the dust box 2 as follows. That is, 22 m / sec. From the tip of the suction hose. ~ 28m / se
c. Particles such as sand, iron powder, iron particles, etc. are forcibly sucked into the dust box 2 at the suction speed described above, and the upper suction port 5 of the dust box 2 has a large diameter.
m / sec. To 6 m / sec. As a result, the dust having a large specific gravity falls downward due to the relative velocity difference, and the dust is automatically separated from the fine dust. It flows into. 2 and 3, reference numeral 6 denotes a chute provided below the dust box 2, reference numeral 7 denotes a handle, reference numeral 8 denotes a machine leg, and reference numeral 12 denotes dust.

[0013]

According to the present invention, centralized suction by the central suction pump and reduction of dust transport energy by separation of light-weight dust by the main pipe and branch pipe and the dust box can be achieved. As a result of the separation, clogging in the piping can be prevented beforehand, and a remarkable effect can be obtained at low cost (both equipment and operation costs), which can collect light and heavy dust from various parts of the factory efficiently and comprehensively. .
