Description

  The present invention belongs to the technical field of a dust removing device that removes dust (dust) generated in the air due to work or construction on site and discharges clean air from which dust has been removed to the site again. Is.

Today, it is used in homes and offices, and is used as a dust removal device that collects and removes dust scattered in the air and discharges clean air without dust. There is known a device that purifies the air by passing it through (for example, Patent Document 1). However, in this case, it is not preferable from the viewpoint of pollution to discard the collected water contaminated with dust as it is, and it is required to separate the water and dust for disposal.
In view of this, there is known a dust removing device that collects dust that has been ionized or brought into a charge-carrying state by electric discharge so that water is unnecessary (for example, Patent Documents 2 and 3).

The ring 26 vibrates the filter 17 in conjunction with the back-and-forth reciprocating movement of the support shaft 23, and as a result, the dust adhering to the inner surface of the filter 17 is shaken off and drawn out (dust collecting chamber). ) 21 to drop.

Reference numeral 27 denotes a control panel. The control panel 27 is provided on the front surface of the fan chamber 2, and the dust removal chamber 3 is provided in a range of a space protruding forward from the front end surface of the fan chamber 2. Various member devices such as switches for executing drive control of the fan 5 and the motor 25 are provided.
When the fan 5 is driven, the dust removal chamber 3 has a negative pressure, and the outside air mixed with the dust is sucked from the front end surface 3a and the projecting upper end surface 3b serving as the intake port and flows into the dust removal chamber 3, and The air is sucked into the filter cylinder from the upper end face of the filter 17 via the dust mixed air flow path A, where the dust is removed (filtered), and the clean air from which the dust has been removed is sucked out of the cylinder of the filter 17. Is done. The dust-removed air reaches the dust-removed air flow path C from the dust-removed flow path B through the opening 15 and is discharged out of the apparatus 1 through the discharge filter 4.
Reference numeral 28 denotes a viewing window provided in the dust removal chamber 3 so that the state of the filter 17 can be seen from the viewing window 28. Reference numeral 29 denotes a caster for moving the apparatus 1.

  In the embodiment of the present invention configured as described above, dust-mixed air mixed with dust (dust) generated in the air due to on-site work or construction is removed by driving the fan 5. The air that has been sucked into the chamber 3 and removed by the filter 17 to become clean air free of dust is discharged outside the machine, so that the dust-mixed air can be cleaned in order to recycle the air at the site. It can be done continuously.

  As described above, in the embodiment of the present invention, dust removal from the dust-mixed air is performed using the filter 17, and the filter 17 has a cylindrical shape, and the dust that has entered the cylinder from the upper opening. When the mixed air goes out of the cylinder through the filter 17, dust is removed, and the removed dust adheres to the inner cylinder surface of the filter 17 or falls to a drawer 21 below the cylinder. If dust adheres to the filter 17 in this way, the dust removal capability may be reduced and there is a fear, but when this happens, the fan 5 is stopped and the dust removal operation of the dust-mixed air is stopped. When the motor 25 is driven to reciprocate the ring 26 back and forth, the ring 26 forcibly vibrates the filter 17, whereby the dust adhering to the inner surface of the cylinder is separated from the filter 17, and the separated dust Is collected in the drawer 21 facing downward by falling in a dry state. After such a detachment of the dust and the dust collecting operation are repeated several times, the dust collected in the drawer 21 can be easily discarded by pulling out the drawer 21.

  In addition, in this case, the filter 17 has a truncated-conical shape having a small diameter on the lower side. Therefore, when the filter 17 is set, not only the work is facilitated by inserting from the small diameter side, Efficient air purification by ensuring a sealed set between the upper partition plate 12 and the support plate 19 at the end and preventing leakage of contaminated air to the dust removal passage B side Will be able to.

  Further, at the end of the work or at the time of a break, the air purification work can be stopped and the motor 25 can be driven to perform the cleaning by vibrating the filter 17. It can be used in a state with good dust removal performance for a long period of time by eliminating clogging. When the filter 17 is finally clogged and it is necessary to check the clogging status by visual inspection or to replace the filter 17, the upper fan chamber 2 is opened and the rear upper partition plate 16d is swung backward. As a result, all the filters 17 are exposed upward, and the filters 17 are extracted and individually inspected to remove dust and prepare for reuse, or maintenance such as inspection and replacement work such as replacement with a new filter. Is easy to do.

  Moreover, since the filter 17 has a truncated circular water bottle shape with a smaller diameter on the lower side, not only is the filter 17 easy to set, but sealing at both upper and lower ends is ensured. In addition, since the filter 17 is pressed by the pressing plate 18, the sealing performance is further improved.

  In addition, in this apparatus, the apparatus 1 has an upper and lower laminated structure in which the fan chamber 2 is arranged on the upper side and the dust removal chamber 3 is arranged on the lower side, so that the upper and lower spaces can be effectively used. It can be prevented from becoming large in the left-right direction, and can be transported by an elevator.

  Note that the present invention is not limited to the above-described embodiment, and various modifications such as exhausting the fan chamber to the ceiling surface can be made. This makes it possible to move the floor of the building, which is convenient for interior work. Furthermore, if a hook hook is formed on the ceiling surface of the dust removing device, it can be hung by a crane. Also, if the exhaust filter provided in the fan chamber is a filter with a smaller mesh than the filter provided in the dust removal chamber, for example, a high-performance filter (such as HERA) with high dust removal performance, the air from which dust has been removed in the dust removal chamber In addition, dust of a small particle size can be removed, and air can be further purified.
