Abstract

PURPOSE:To efficiently collect iron dust by detachably inserting a magnet in a cylindrical vessel formed out of nonmagnetic or paramagnetic material to make a dust collecting unit, and arranging it in the upstream side of a motered fan. CONSTITUTION:The cylindrical vessels 2 formed out of nonmagnetic or paramagnetic material such as alminum or plastics are provided to a receiving case of a dust collector main body. And the cylindrical vessel 2 and a magnet 1 received therein constitute a dust collecting unit 3. These dust collecting units 3 are arranged in the upstream side of the motor fan 5. Accordingly, when the motor fan 5 is driven, the iron dust in the air moved to the direction shown by arrow A are attracted by the magnetic force of the dust collecting units 3 and removed. When the magnet 1 is withdrawn upward, the iron dust are fallen down on a receiving plate 6, and the iron dust are very easily collected.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dust collector for collecting iron dust generated during the operation of an air plasma cutter, laser processing machine, welding machine, etc.

Conventional technology Generally air plasma cutter, laser processing machine.

As a dust collector for collecting iron dust generated during the operation of welding fumes, etc., a mechanical filter 1o is used as shown in Figure 3.
There were dust collectors that collected dust using a dust collector, and dust collectors that collected dust using an electric dust collection method as shown in Figure 4.

To explain the dust collector shown in FIG. 3, 10 is a mechanical filter, 11 is a dust collector body storage case, and 12 is a motor fan. To explain the dust collector shown in FIG. 4, 2o is an ionization wire, 21 is a dust collection electrode plate, 22 is an auxiliary electrode plate, and n and others constitute an electrode dust collection unit 23.

Problems to be Solved by the Invention However, mechanical filter 1 as shown in FIG.
In a dust collector that collects dust using 0, the mechanical filter 10 becomes clogged in a short period of time. Further, in a dust collector that collects dust using an electric dust collection method as shown in FIG. 4, cleaning of iron dust adhering to the electrode dust collection unit 23 requires washing with water, making maintenance difficult.

The present invention solves these conventional problems and provides a dust collector that can collect a large amount of iron dust with a simple configuration and is extremely easy to maintain.

Means for resolving problems The dust collector of the present invention is made of a non-magnetic material or a paramagnetic material.
A cylindrical container with an opening in at least one direction,
It is equipped with a dust collection unit into which a magnet is removably inserted, and this dust collection unit is arranged on the windward side of the motor fan.

Function: The dust collector of the present invention collects iron dust adhering to the surface of a cylindrical container by the magnetic force of a magnet, and then removes the magnetic force acting on the iron dust by removing the magnet from the container. The adhering iron dust is stained and washed away by gravity into the lower tray.

EXAMPLE Hereinafter, an example of the dust collector of the present invention will be described with reference to the drawings. FIG. 1 shows a sectional view of the dust collector of the present invention. FIG. 2 is a plan view of the dust collector. In Figures 1 and 2, 4 is a storage case for the dust collector main body, and a cylindrical container 2 made of non-magnetic or paramagnetic material such as aluminum or plastic and having an opening in one direction is used to store the dust collector main body. Case 4 is defeated. And magnet 1 is
It is housed in a cylindrical container 2. Magnet 1 and cylindrical container 2
are combined to form the dust collection unit 3. This dust collection unit 3 is arranged on the windward side of the motor fan 6. The motor 77 moves the air from the contaminated air direction A toward the clean air flow direction B. 6 is a tray for collecting dust.

The operation of the dust collector constructed as above will be explained below.

First, when the motor fan 5 rotates, contaminated air containing iron dust moves in the direction shown by arrow A, and the iron dust is attracted to the surface of the cylindrical container 2 by the magnetic force of the magnet 1 of the dust collection unit 3. It is attached. And the iron dust was removed n1
The purified air moves in the direction shown by arrow B.

Then, when the magnet 1 is moved upward in FIG. 1 and removed from the cylindrical container 2, the iron dust that had previously been attached to the surface of the cylindrical container 2 due to magnetic force will be removed by gravity because the magnetic force is gone. It falls downward and is collected in the saucer 6.

As described above, according to this embodiment, a large amount of iron dust can be collected with a very simple configuration, and the attached iron dust can be easily collected.

Effects of the Invention As described above, the dust collector of the present invention can collect a large amount of iron dust generated during the operation of an air plasma cutter, laser processing machine, welding machine, etc. with an extremely simple configuration. And by moving the magnet, iron dust can be collected very easily, and its practical value is that of a dog.
