Abstract

To solve problems in which scattering of contents and contamination in the environment are caused by deformation of a cleaner paper pack (paper pack), as it is necessary to pull out the paper pack in exchanging it after sucking harmful objects by a paper pack type cleaner and in which, in the case of inflammable harmful object, no paper pack is used because of spark/heat from an inner motor.SOLUTION: The paper pack can be attached and removed from outside of the cleaner, and the paper pack can be discarded directly into a vinyl bag. In addition, by switching the suction motor of the cleaner and an exhaust port for external connection, inflammable harmful object can be dealt with.SELECTED DRAWING: Figure 1

Description

The present invention relates to a vacuum cleaner for collecting harmful substances of a unit capable of sucking harmful substances generated in a production / manufacturing process into a paper carton type vacuum cleaner and disposing of them without touching the human body.

As a work method to remove harmful substances generated in the manufacturing process of semiconductor products in the cleaning process, wear safety protective equipment such as protective masks, goggles, and apron, remove the lumps with a handling tool, and then use a vacuum cleaner for a clean room. I was inhaling harmful substances.

With this method of work, powdery toxic substances can scatter and contaminate clean areas when removing lumps.

In addition, when disposing of harmful substances sucked into the clean room vacuum cleaner, it is necessary to replace the vacuum cleaner paper pack inside the vacuum cleaner.

At the time of replacement, the inset type vacuum cleaner paper pack is taken out, and the work is done in a draft with an exhaust facility to prevent the scattering of harmful substances due to the deformation of the vacuum cleaner paper pack.

When collecting harmful substances from the equipment, they are mainly collected in the vacuum cleaner paper pack of the suction device, but when the vacuum cleaner paper pack is pulled out and replaced, harmful substances due to damage to the vacuum cleaner paper pack are scattered. Contamination due to odor occurs.

In addition, the paper pack will be exposed from the time the vacuum cleaner paper pack is pulled out until it is stored in a plastic bag, which may lead to contamination of the surrounding area.

In addition, there are electrical parts of the vacuum cleaner near the vacuum cleaner paper pack, which makes it impossible to deal with flammable harmful substances.

The present invention has a structure in which the vacuum cleaner paper pack can be fixed by using a magnet from the outside of the vacuum cleaner for collecting harmful substances, so that the vacuum cleaner paper pack does not require force when the vacuum cleaner paper pack is replaced. You can prevent the surrounding pollution without deforming itself.

Also, by removing the paper pack unit, you can put the paper pack unit in a plastic bag and release the vacuum cleaner paper pack, so that you can dispose of it in the plastic bag without touching the vacuum cleaner paper pack that has inhaled harmful substances. ..

In the case of ignitable harmful substances, even if the vacuum cleaner itself cannot be used due to motor sparks or heat generation, it can be used even with ignitable harmful substances by switching the suction port to an external suction port.

When collecting solid hazardous substances discharged from production equipment with a vacuum cleaner, the safety of workers can be improved by disposing of them without touching the vacuum cleaner paper pack of the container to be collected.

In addition, for harmful substances that have a risk of ignition, by connecting an external vacuum cleaner, it is possible to keep away the ignition factors and improve the safety of workers.

Hereinafter, the vacuum cleaner for collecting harmful substances according to the embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the toxic substance recovery vacuum cleaner has a vertical box or cylindrical shape when viewed from the front, and is composed of an upper paper pack unit 3 and a lower motor unit 5.

The paper pack unit 3 has a paper pack fixing bracket 12 and a paper pack hood 11 inside, and a suction port 1 for sucking harmful substances and a unit connecting bracket 6 for connecting to the motor unit 5 on the outside. Using the unit connection fitting 6 and the unit connection fitting 6a on the motor unit side, the paper pack unit 3 and the motor unit 5 are connected and fixed.

As shown in FIG. 2, there is a paper pack hood 11 made of wire mesh or a punched hole on the entire surface so that the vacuum cleaner paper pack 10 does not bulge too much, and there is a edge 11a of the same material at the bottom, and the cylinder part is a truncated cone , Has a truncated cone.

As shown in FIG. 3, in the paper pack solid metal fitting 12, a hinged paper pack fixing plate 19 is fitted between the bag portion of the vacuum cleaner paper pack 10 and the mounting thick paper portion, and the suction port 1 is used as a guide. Using the paper pack attachment / detachment magnet 7, the paper pack fixing plate 19 is attracted by magnetic force to fix the vacuum cleaner paper pack 10 to the paper pack unit 3.
The paper pack fixing plate 19 is processed so that the contact surface with the vacuum cleaner paper pack 10 has irregularities to prevent slipping.

When disposing of the vacuum cleaner paper pack 10 containing harmful substances sucked from the suction port 1, bring the paper pack unit 3 onto the plastic bag 14 as shown in FIG. 5, and attach the paper pack attachment / detachment magnet 7 to the suction port 1. By removing it from the paper pack fixing plate 19, the magnetic force of the paper pack fixing plate 19 is lost, and the vacuum cleaner paper pack 10 naturally falls into the plastic bag 14 and can be discarded.

As shown in FIG. 4, the motor unit 5 includes an intake motor 13 integrated with an intake motor hood 18 inside, an intake motor on-off valve 8 for switching between an external connection exhaust port 2 and exhaust, and an exhaust port on-off valve. There are nine.

The exhaust port on-off valve 9 opens due to the negative pressure of the suction equipment connected to the subsequent stage, and is normally closed by a spring in the exhaust port on-off valve 9.

The on-off valve 8 for the intake motor is opened by the solenoid at the same time when the intake motor 13 is energized by the start switch in the operation panel 15, and the on-off valve is closed when the on-off valve is not energized.

The exhaust port on-off valve 9 is provided with a micro switch 20, and the intake motor 13 is not energized when the exhaust port on-off valve 9 is open.

A replaceable motor unit filter 4 is attached to the upper part of the motor unit 5 so that harmful substances leaking from the gap of the vacuum cleaner paper pack 10 do not flow into the motor unit 5.

The motor unit filter 4 is provided with a mesh-shaped or wire mesh-shaped spacer 21 that also protects the motor unit fluter 4 so as to support the vacuum cleaner paper pack 10 from below in a state where the vacuum cleaner paper pack 10 is inflated. ing.

By connecting the paper pack unit 3, the motor unit 5, and the unit connection fitting 6, it can be used as a vacuum cleaner for collecting harmful substances, and by sucking from the exhaust port 2 for external connection, the vacuum cleaner for collecting harmful substances can be collected. As a container, it can also be used for toxic substances that are ignitable due to the heat generated by electric sparks and motors.

In addition to driving the vacuum cleaner, the control board 16 has overcurrent, negative pressure, on-off valves for intake motors and exhaust ports, moisture detection, temperature for motors and paper pack units, and connection detection for exhaust ports as safety measures. is there.

Although the suction method is safe when collecting harmful substances and wastes that affect the human body, multiple protective devices are used to prevent the effects of scattering and diffusion when taking out the harmful substances collected after suction. You need to wear and work. By using the vacuum cleaner for collecting harmful substances of the present invention, the occupational safety of workers can be improved.
