Description

{A VACUUM CLEANER USING IN SHIPYARD}

The present invention relates to a vacuum cleaner for shipbuilding.

In general, building a ship involves proceeding through a series of work processes in which the hull blocks are assembled, welded, and painted in the dock.

Particularly, foreign matter such as welding slags generated during welding, and abrasive particles generated during the surface treatment (grinding) for painting are generated on the floor of the worksite.

Therefore, it is necessary to carry out the work of removing the foreign substances occurring on the floor of the workplace at any time, and an industrial vacuum cleaner, which operates mostly by vacuum absorption, is used for such foreign matter removal work.

Such an industrial vacuum cleaner includes an industrial vacuum absorption cleaner of Utility Model Registration No. 20-0031498.

However, the industrial vacuum absorption type vacuum cleaner of Utility Model Registration No. 20-0031498 is a motor drive type structure having a motor (hereinafter referred to as "motor.") As a drive device for generating a vacuum absorption force, Such a motor driving method is disadvantageous in that it is complicated in structure because a motor must be provided in the cleaner main body, and handling easiness is not good due to increase in the weight of the vacuum cleaner due to installation of the motor.

Further, in order to drive the motor, for example, an electric outlet and an electric connection line must be additionally provided, so that it is inconvenient to remove foreign matter while moving in the workplace, and always exposed to serious safety accidents such as electric shock There is a problem.

The vacuum cleaner for shipbuilding according to an embodiment of the present invention can remove the foreign substances W generated in the ship drying workshop S by using the supply hose S2 of the air supply device S1 as shown in FIG. Is connected to the side of the pressure generating portion 8 to supply the air R to the inlet port B1 side of the separating portion 4. [

A suction force is generated on the side of the head portion 6 by the venturi action caused by the pressure of air R supplied to the inflow port B1 so that the foreign substances W on the floor surface of the workplace S1 are guided to the head portion 6 As shown in FIG.

The foreign matter W flowing through the head part 6 may be supplied to the separating part 4 and may be separated and collected in a cyclone manner.

That is, when the foreign substances W are supplied to the separation space B of the separation unit 4, they are moved in a spiral shape from the upper side to the lower side along the inner peripheral surface of the separation space B as shown in FIG. 5 The air R and the fine dust (not shown) are discharged to the outside through the filter port C1 or the silencer C2 through the discharge port B2.

For example, the foreign particles W in the form of particles generated in the welding slug or the grinding are collected in the receptacle C3 via the collection port B3 in the lower part of the separation space B.

Therefore, the present invention can be applied to a foreign matter W in the worksite S by using the air R of the conventional air supply device S1 provided in the workplace S, without integrally providing a drive source such as an electric motor, Can be removed easily and quickly.
