The dust collecting device of the present invention is structured to be horizontally installed and structurally stable as shown in FIG. 1, and is capable of discharging the purified air to the downstream end of the dust collecting device.

The inlet (2) is formed in a funnel shape so as to be able to effectively collect welding dust and smoke by directly contacting the welding site. The dust and smoke collected through the inlet (2) 4 into the dust chamber 8 through the discharge port.

In the present invention, the inflow pipe 4 is formed in a flexible form so that the inflow portion 2 is not fixedly installed at a specific position in the workplace but is moved to a position where actual welding operation is performed, It can collect dust and smoke more effectively.

The welding dust and the smoke collected through the inlet portion 2 and the inlet pipe 4 include flames generated during welding. Such flames may cause a fire due to dust in the dust receptacle 8.

In the present invention, a first filter unit 6 made of STS (Stainless Steel) made of mesh is installed to remove flames contained in welding dust and smoke to prevent flames from entering the dust box 8 .

The dust in the dust and smoke collected in the dust box 8 after the flame is removed by the first filter portion 6 is separated by the second filter portion 10 and collected in the dust collecting box 8, (12).

In the present invention, the welding dust is firstly collected by the second filter portion 10 made of a plurality of pockets made of polyester material, and the smoke from which the dust is removed is sucked into the downstream process.

Since the second filter unit 10 is formed in a plurality of pockets, the unit area for collecting the dust increases and is more effective than one filter installed in the same space. 10, it is easy to shake off dust.

In the present invention, the end portion of the second filter portion 10, which is provided in the form of a plurality of pockets on the side surface of the second filter portion in order to remove the dust adhered to the second filter portion 10 at the time of collecting the welding dust, (Not shown).

Since the second filter unit 10 is for separating the welding dust from the smoke, if the welding dust adheres to the second filtering unit, the suction force of the suction unit 16 at the rear end is lowered, Performance may be degraded.

The dust removing shaft 14 is for collecting dust attached to the second filter unit 10 when a plurality of pockets of the second filter unit 10 are integrally connected and the performance of the dust collecting apparatus is deteriorated, , The dust removing shaft 14 horizontally installed is moved to the left and right to shake the second filter unit 10 so that the attached dust is collected and collected in the lower collecting cylinder 12. [

The deasphalting shaft 14 can be automatically operated by the control unit 20 described later.

The dust introduced into the dust box 8 is collected by the second filter section 10 in the collection tube 12 and the smoke is passed through the second filter section 10 by the suction section 16 .

The suction unit 16 controls the suction capacity of the suction unit 16 by controlling the rotation speed of the motor 18 by the inverter of the control unit 20 and the suction capacity of the suction unit 16 is controlled by the motor 18.

As a preferred embodiment, the suction unit 16 may be an impeller.

The control of the rotational speed of the motor 18 by the control unit 20 adjusts the smoke suction force by the suction unit 16 and is controlled by one side of the motor 18, And the suction smoke detector 22 detects the amount of the smoke introduced by the suction smoke detector 22 provided at the rear end of the suction unit 16. The smoke detector 22 may be a smoke sensor.

In the process of sucking the smoke collected in the dust box 8 by the suction unit 16, the dust can be normally sucked in the state where the dust is not attached to the second filter unit 10. However, The dust suction amount of the smoke is reduced when dust is adhered to the dust receptacle 10.

This causes the deterioration of the performance of the dust collecting apparatus. At this time, the control unit 20 confirms the amount of the smoke to be sucked by the suction smoke detecting unit 22 and increases the rotating speed of the motor 18 when the suction amount of the smoke is reduced So that the smoke suction force by the suction portion 16 is increased.

That is, by controlling the rotation speed of the motor 18 according to the amount of the suction smoke sensed by the suction smoke detection unit 22, the motor 18 is prevented from being overloaded, and the dust collection can be maintained at a constant performance do.

The suction smoke detection unit 22 may be a manometer and measures the pressure of the smoke sucked by the suction unit 16. When the suction pressure is lowered, It is possible to control the rotation speed of the motor 18 through the control unit 20 to be increased.

The control unit 20 controls the rotation speed of the motor 18 in accordance with the amount of smoke intake so that the motor 18 is operated for a long time or too much dust is attached to the second filter unit 10, And has an automatic power-off function to prevent overloading of the motor 18, which is generated to compensate for the suction force.

A temperature sensor 24 for sensing the temperature of the motor 18 may be installed inside the motor 18. The temperature value of the motor 18 measured by the temperature sensor 24 may be supplied to the controller 20 .

When the motor 18 rises above the set temperature, the controller 20 receives the temperature value of the motor 18, determines that an overload has occurred, cuts off the power supplied to the motor 18, It is possible to prevent the motor 18 from being damaged.

Also, the control unit 20 may control the automatic dust removing shaft 14 for shaking dust attached to the second filter unit 10, which has been described above.

When the amount of suction smoke detected by the suction smoke detector 22 decreases, the control unit 20 generates an operation signal of the dust removing shaft 14 so that the dust removing shaft 14 reciprocates several times to the left and right And stops the operation when the smoke suction amount detected by the suction smoke detection unit 22 becomes equal to or higher than a predetermined value while dust is removed from the second filter unit 10 by the dust removing shaft 14. [

In the present invention, the third filter portion 26 for purifying the smoke inhaled in the dust box 8 and discharging it to the work place is installed at the rear end of the dust collecting device.

As a preferred embodiment, the third filter unit 26 may be a high efficiency particulate air filter (HEPA filter) made of glass fiber. The third filter unit 26 may be made of fine particles, By filtering, the worksite can be prevented from being contaminated again by the air discharged.
