The dust collecting apparatus 1 according to the present invention includes an air distribution unit 300 and the air distribution unit 300 includes a predetermined pipeline and a predetermined compressed air supply unit P, (310) having a through-hole (316) penetrating in a lateral direction connecting the first distributor body (170) and a second distributor body A second partition body 320 connected to the first partition body 160 and having an air hole 326 formed on the side thereof, a side passage 330 connecting the through hole 316 and the air hole 326, A control valve 340 disposed to penetrate the first distributor body 316 and displaced in the conduit of the first distributor body 310 to contact or separate from the lateral passage 330 to control the opening and closing degree of the lateral passage 330, . &Lt; / RTI >

The first distributor body 310 and the second distributor body 320 are configured in the form of a pipe having predetermined conduits 314 and 324, respectively. The first distributor body 310 connects the predetermined compressed air supply device W and the air discharge line 170 so that air supplied from the compressed air supply device W is transferred to the air discharge line 170 Guide. The second distributor body 320 connects the air suction line 160 and the filter unit 400 and guides the air sucked in the air suction line 160 to be transferred into the filter unit 400. The first distributor body 310 and the second distributor body 320 are disposed side by side in the lateral direction.

A through-hole 316 is formed in the side of the first distributor body 310. A side of the second distributor body 320 is provided with a predetermined air hole 326 through which air can flow, . The through hole 316 and the air hole 326 are connected to each other through a predetermined lateral passage 330 so that air can flow.

A control valve 340 is disposed in the through hole 316. The control valve 340 has a predetermined head 346 and has a configuration capable of sealing the through hole 316 by making contact with and contacting the lateral passage 330. 28 and 27, the control valve 340 is displaced in the lateral direction of the first distributor body 310 so that the lateral passage 330 (see FIG. 28) Or spaced therefrom, and the spacing distance is variable by operation. Accordingly, the control valve 340 includes a head 346 that is in intimate contact with the lateral passage 330, a connecting beam 344 that extends from the head 346 and contacts the inner circumferential surface of the through hole 316, And may have a grip portion 342 that the user can grasp. The control valve 340 may be displaced by operating the grip portion 342, and may be configured to be displaced according to the rotation of the grip portion 342 by having a predetermined screw connection, for example.

The compressed air supplied into the first distributor body 310 in connection with the compressed air supply device P can be delivered to the air discharge line 170 and the control valve 340 The second distributor body 320 can be opened and closed.

Preferably, the second distributor body 320 includes a front body 328 in the form of a pipe having a predetermined diameter, and a front body 328 having a diameter larger than that of the front body 328, The air hole 326 is formed in a front portion of the rear body 322 connected to the front body 328 and the air hole 326 is formed in a predetermined A through hole 316 having a diameter is formed to penetrate in the front-rear direction, and a plurality of the through holes 316 may be arranged in the circumferential direction of the rear body 322.

Figs. 19, 20, and 21 show side, cross-section, and front views of the second distributor body 320, respectively. 18 and 20, the second distributor body 320 includes a tubular front body 328 having a predetermined diameter and a rear body 322, and the rear body 322 And the air hole 326 is formed in a front portion of the rear body 322 connected to the front body 328. The rear body 322 has a diameter larger than that of the front body 328, Accordingly, the air holes 326 may have a configuration in which a plurality of through holes 316 having a predetermined diameter pass through in the front-rear direction.

The compressed air delivered through the lateral passage 330 is delivered to the second distributor body 320 through the air hole 326. [ At this time, as the air hole 326 has a relatively small inner diameter, the velocity of the compressed air can be accelerated, and the accelerated air is injected toward the rear along the penetration direction of the through hole 316. Accordingly, the air injected rearward has a force for sucking air in front, and air is sucked through the air suction line 160.

That is, as shown in FIG. 16, the air that is transmitted laterally through the lateral passage 330 passes through the air hole 326 and is deflected rearward. At this time, the air hole having a relatively small inner diameter 326, the speed is accelerated. The air that is accelerated and injected has a force for sucking air in the front, so that air can be sucked.

The degree of opening and closing of the lateral passage 330 is adjusted by adjusting the distance between the lateral passage 330 and the control valve 340 by operating the control valve 340, Can be adjusted. That is, the operation of the dust collecting apparatus 1 according to the present invention can be appropriately controlled by controlling the air suction force and the air discharge power according to the operation of the control valve 340.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
