Description

DUST CLEANING APPARATUS

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration damping device, and more particularly, to a vibration damping device capable of recovering dust (DUST) such as dust and dust generated in a work space to improve a clean working environment.

Generally, in a work space such as a steel coke process, dust (dust, dust, etc.) is generated in many places. In order to clean the work space, dust must be collected and removed.

Conventionally, dusts collected around the workplace equipment must be manually collected, and the collected dust must be transferred to other surrounding storage sites. Therefore, dust removal efficiency is low and dust removal is time-consuming and labor intensive.

Meanwhile, a dust collector for sucking dust by suction through a suction blower has been developed. Such a dust collector sucks dust through the suction blower and collects the dust in the dust collecting portion of the apparatus, so that the dust removing operation is convenient.

However, the conventional dust collector sucks and collects the dust, and then the dust collected in the dust collecting unit must be manually moved to a different storage place. Therefore, there is still a problem in that it takes much time and effort to remove the dust.

In addition, since the dust attached to the filter of the collecting part must be shaken by hand to separate the dust, the dust separation operation is inconvenient and the dust and dust separation operation is not good for the health and hygiene of the operator.

The filter protection tube 350 protects the filter bag 330 by preventing dust, which is sucked into the collection chamber 310, from directly colliding with the filter bag 330. In addition, the dust is sucked through the space between the collecting chamber 310 and the filter protecting pipe 350 and is sucked through the lower opening of the filter protecting pipe 350 and is filtered into the filter bag 330.

The length of the lower end portion of the filter protection pipe 350 is gradually increased from one side to the other side so that the lower opening 351 is inclined so that the dust inside the collection chamber 310 is separated from the lower inclined opening 351 So that the filter bag 330 can be smoothly sucked.

The dust separator 400 includes an air injection nozzle 410 located at an upper portion of the filter bag 330 and separating the dust collected in the filter bag 330 by injecting high pressure air into the filter bag 330 .

The air injection nozzles 410 are formed of a plurality of air injection nozzles 410. The air injection nozzles 410 pass through a plurality of nozzle insertion holes 311a formed in the upper side of the collecting chamber 310 and are spaced slightly upward from the upper end of each filter bag 330, . At this time, each of the air injection nozzles 410 is arranged so as to inject high pressure air to each filter bag 330. For example, when three air jet nozzles 411, 412 and 413 are arranged side by side and four filter bags 331, 332, 333 and 334 are circularly arranged as shown in FIG. 8, The first air injection nozzle 441 is arranged to cross the upper part of the first filter bag 331 and the second air injection nozzle 442 is arranged to cross the upper part of the second filter bag 332 and the third filter bag 333 And the third air injection nozzle 443 may be arranged to traverse the upper portion of the fourth filter bag 334. [ The number of the air injection nozzles 410 and the number of the filter bags 330 is not limited to four, but the present invention is not limited thereto. It can be set appropriately according to the design. Each of the air injection nozzles 410 is connected to an air tank 420, and the air tank 420 is connected to a compressor 430 to supply high-pressure air.

The rotary valve 500 is installed at a lower portion of the collecting chamber 310 and is connected to the discharging unit 200 and connected to the motor 501 by a belt. The rotary valve 500 is arranged so that the valve diaphragm rotating body 510 rotates and separates from the filter bag 330 to discharge the dust falling down to the lower portion of the collecting chamber 310 to the discharge portion 200 uniformly. . The rotary valve 500 also serves to prevent the dust from flowing back to the upper portion of the rotary valve 500, that is, the collecting chamber 310 when the dust is discharged to the discharge pipe 210 or conveyed through the transfer hose pipe 220 . Since the rotary valve 500 is a known construction, detailed description thereof will be omitted.

The dust collecting apparatus of the present invention configured as described above is used for collecting dust such as dust, dust, etc., generated in a working space such as a steelworks coke process, and transferring the dust to another storage place in the vicinity to improve a clean working environment. When the first blower 610 is operated, the dust is sucked through the suction head 120 and the suction pipe 110, and the sucked dust is collected in the filter bag 330 in the collecting chamber 310. At this time, the dust containing the dust sucked into the dust collection chamber 310 is not directly collided with the filter bag 330 by the filter protection pipe 350 formed in a cylindrical shape so as to surround the outside of the filter bag 330, (330). The dust is sucked through the space between the dust collecting chamber 310 and the filter protecting pipe 350 and sucked through the lower opening 351 of the filter protecting pipe 350 and filtered by the filter bag 330, And moves to the first blower 610 through the suction connection pipe 130 connected to the upper part of the sealing lid 320. When dust of high pressure is injected into the upper portion of each filter bag 330 through the air injection nozzle 410, the dust 1 (see FIG. 9) attached to the filter bag 330 is discharged from the filter bag 330 And falls to the inner bottom surface of the collecting chamber 310 while being separated. Therefore, the dust collected in the filter bag 330 can be automatically shaken and removed without requiring the user to manually remove the dust. The dust 1 (see FIG. 10) separated from the filter bag 330 is discharged to the discharge pipe 210 while the rotary valve 500 installed in the lower part of the collecting chamber 310 rotates. At this time, the second blower 620 discharges air to the discharge pipe 210, and the dust is discharged through the discharge unit 200. In addition, the dust discharged through the discharge pipe 210 is transferred to another peripheral store through the transfer hose pipe 220 coupled to the discharge pipe 210, thereby improving a clean working environment. Further, since the moving wheel 730 is provided below the base portion 700 of the vibration isolation device, the dust removing operation can be performed while moving every corner of the work space.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken in conjunction with the present invention. You will understand. It is therefore to be understood that the embodiments described above are in all respects illustrative and not restrictive. It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
