Description

  The present invention relates to an air cleaning device, and more particularly to an air cleaning device that adsorbs dust and oil mist to a filter.

  For example, in a factory where machine parts are machined, such as cutting and grinding, when machining these parts, a large amount of dust and chips are generated and oil mist is generated by cutting oil. There is concern that the environment will deteriorate. Also, if oil mist adhering to dust or chips gradually adheres and accumulates on equipment in the factory, it may cause malfunction of the equipment or corrosion, or the operator may fall down due to oil mist adhering to the floor or wall, etc. It is considered that problems such as ignition of oil mist and fires may occur. In order to effectively avoid such a situation, various air purifiers for purifying air in which dust and oil mist are floating, that is, mixed are proposed.

  For example, Patent Document 1 proposes an air cleaning device that uses an attracting action of a turbo blower. The air cleaning device disclosed in Patent Document 1 has a cylindrical main body that is open at the top, a main body that houses a cylindrical filter, an upper portion of the main body that is closed, and an intake motor and a turbo blower. A fan case that is accommodated is provided, and the fan case is covered with a lid. A suction port is formed in a cylindrical shape on the peripheral wall of the main body, and a discharge port is formed on the side wall of the fan case. By driving the turbo blower, outside air is sucked from the suction port, and foreign matters such as dust are adsorbed and cleaned by the filter, and the cleaned air is discharged from the discharge port.

  The air cleaning device disclosed in Patent Document 2 includes an air cleaning device main body having a plurality of cylindrical filters. The air cleaning device main body sucks outside air into the air cleaning device main body from a dust suction port and accommodates pulverized coal. The pulverized coal is sucked from the pulverized coal tank, and dust and pulverized coal are adhered to the inner surface of the filter to clean and deodorize the outside air in the work space.

  The air cleaning device described in Patent Document 1 is for sucking and cleaning outside air mixed with dust and the like from a suction port, and sucks outside air from a suction port provided locally on the peripheral wall of the main body. Therefore, there is a concern that efficient cleaning cannot be performed as an air purifier in a factory that cleans the outside air in which a large amount of oil mist and dust floating in the work space float. For this reason, it is necessary to install a large number of air purifiers in the factory. However, since equipment in the manufacturing and processing line for parts etc. is arranged in the factory for rationalization of work, a large number of air purifiers are arranged. In many cases, it is difficult to secure an installation space, and an appropriate air cleaning device may not be arranged. In addition, there are concerns about the equipment cost due to the installation of a large number of air purifiers, the work burden accompanying the increase in the number of filter replacements, and the increase in maintenance costs.

  Further, according to the air cleaning device described in Patent Document 2, although the cleaning performance is enhanced by a plurality of cylindrical filters, outside air is sucked from a dust suction port disposed locally as in Patent Document 1. Therefore, there is a concern that it cannot be efficiently cleaned as an air cleaning device in a factory. Therefore, similarly to Patent Document 1, a large number of air purifiers are required, and there is a concern that the equipment cost, work burden, and maintenance cost will increase.

  Accordingly, an object of the present invention made in view of such a point is to improve the working environment by efficiently removing dust and oil mist mixed in the outside air, and to reduce the equipment cost and the maintenance cost. It is to provide a cleaning device.

The roll filter F is held on the filter support portion 52 by fitting with the shaft 53 and bringing the lower end surface Fd into contact with the filter stopper 54. Subsequently, the roll support arm 57 is swung downward, the second filter support shaft 58 is inserted into the upper end of the core member Fh, and the filter support panel 58a is brought into contact with the upper end surface Fc.

  Thus, the roll filter F is rotatably supported by the first filter support shaft 53 and the second filter support shaft 58 inserted at the lower end and the upper end of the core material Fh, and the filter stopper 54 is separated from the filter stopper 54 by its own weight. Both end surfaces of the lower end surface Fd and the upper end surface Fc of the roll filter F are held from above and below by the filter support panel 58a and are supported by the roll filter holding unit 51 in a stable state.

  After that, the first open / close panel 32 is closed, and the end Fb of the filter Fa is drawn out from the roll filter F rotatably held by the roll filter holding unit 51, bypassing the open end 32b of the first open / close panel 32, The second opening / closing panel 34 is closed. Then, the end portion Fb of the filter Fa protruding from the gap S between the opposed open ends 32b and 34b of the closed first open / close panel 32 and the second open / close panel 34 is pulled out, and the drawn out filter Fa is used as the first filter Fa. It is stretched along the outer surface of the open / close panel 32, is further wound around the first filter feed roller 59a and is stretched along the outer surface of the first side surface 23, and is similarly wound around the second filter feed roller 59b to be rear surface 25. The outer surface of the second opening / closing panel 34 is further wound around the third filter feed roller 59c, wound around the outer surface of the second side surface 27, and further wound around the fourth filter feed roller 59d. Tighten along. At this time, the first filter feed roller 59a, the second filter feed roller 59b, the third filter feed roller 59c, and the fourth filter feed roller 59d are rotated following the pull-out of the filter Fa to guide the filter Fa. And it can wind around the outer peripheral surface 21 easily.

  In this way, the end Fb of the filter Fa that covers and covers the outer peripheral surface 21 of the main body 10 over the entire peripheral surface is disposed near the open end 34b of the second opening / closing panel 34. The base portion 37a of the base member 37 and the filter holding member 38 are clamped and held.

  In this way, by operating the air purifier 1 equipped with the roll filter F, that is, by driving the motor 47 and rotating the fan 48, the outside air forms the outer peripheral surface 21 of the main body 10. 25, the second side surface 27, the first open / close panel 32, and the filter Fa covering the second open / close panel 34, and the first side surface 23, the rear surface 25, the second side surface 27, the first open / close panel 32, and the second open / close panel An air flow that is sucked into the main body portion 10 from a large number of suction ports 21 a that open over the entire surface of the panel 34 and discharged to the outside through the discharge port 43 of the fan case 40 from the main body portion 10 is generated.

  The first side surface 23, the rear surface 25, the second side surface 27, the first opening / closing panel 32, and the entire outer peripheral surface 21 of the second opening / closing panel 34 are formed over the entire outer peripheral surface 21. Fine dust and oil mist mixed in the outside air are adsorbed and removed by the filter Fa stretched over the entire surface 21 and sucked into the main body 10 and further deodorized and purified by a deodorant such as activated carbon. Air is discharged from the outlet 43.

  Here, the first side surface 23, the rear surface 25, the second side surface 27, the first open / close panel 32, and the outer peripheral surface 21 of the second open / close panel 34 of the main body 10 are formed over the entire outer peripheral surface 21. Since fine dust and oil mist mixed in the outside air are adsorbed and removed by the filter Fa sucked into the entire surface and stretched over the entire outer peripheral surface 21, the ambient outside air is removed from all directions of the air cleaning device 1 by the filter Fa. The air is sucked into the main body portion 10 through the filter, a large filtration area is secured by the filter Fa, and the dust and oil mist removal capability is improved.

  Further, dust and oil mist introduced into the main body 10 together with outside air without being absorbed and removed by the filter Fa are adsorbed and removed by the filter Fa in the main body 10 and separated from the air flow in the main body 10. Then, it falls on the drain tray placed on the bottom 11 and is received.

  When dust or oil mist adheres to the filter Fa wound around the outer peripheral surface 21 of the main body 10 due to air cleaning and the cleaning ability of the filter Fa decreases, the filter end that holds the end Fb of the filter Fa The part holding part 36 is opened to release the clamp, and the filter Fa is slightly pulled out from the gap S between the open ends 32b and 34b facing each other of the first opening / closing panel 32 and the second opening / closing panel 34. The used part where the dust and oil mist of the protruding filter Fa adheres is cut out and collected.

  Thereafter, dust or oil mist adheres from the roll filter F housed inside the main body 10 by pulling out the end Fb of the filter Fa that slightly protrudes from the gap S formed by cutting off the used part. Unused portions of the filter Fa that are not used are drawn out. In this manner, while pulling out the filter Fa, the filter Fa is stretched along the outer surface of the first open / close panel 32 as described above, and further wound around the first filter feed roller 59a and stretched along the outer surface of the first side surface 23. Similarly, it is wound around the second filter feed roller 59b and stretched along the outer surface of the rear surface 25, and further wound around the third filter feed roller 59c and stretched around the outer surface of the second side surface 27. The four filter feed rollers 59d are wound around and stretched along the outer surface of the second opening / closing panel 34. At this time, the first filter feed roller 59a, the second filter feed roller 59b, the third filter feed roller 59c, and the fourth filter feed roller 59d are rotated to follow the pull-out of the filter Fa, and the filter is wound. By guiding Fa, the outer peripheral surface 21 can be wound smoothly and easily. The end Fb of the wound filter Fa is clamped and held by the base 37a of the base member 37 and the filter holding member 38 of the filter end holding portion 36 disposed in the second opening / closing panel 34.

  When all the roll filters F accommodated in the main body 10 are pulled out, that is, when the remainder is only the core material Fh, the first open / close panel 32 and the second open / close panel 34 are opened and the core material Fh is taken out. After that, a new roll filter F is installed according to the installation procedure of the roll filter F described above.

  Therefore, according to the air cleaning device 1 of the present embodiment configured as described above, the first side surface 23, the rear surface 25, the second side surface 27, the first open / close panel 32, and the outer surface 21 of the main body 10 are provided. Since the second open / close panel 34 has suction holes 21a over the entire surface, and the filter Fa drawn from the roll filter F is wound and covered over the entire outer peripheral surface 21. It becomes possible to inhale outside air from all directions of the air cleaning device 1 without limiting the direction of outside air inhalation. In other words, a large filtration area by the filter Fa over the entire outer peripheral surface 21 is secured, and the dust and oil mist cleaning capability is enhanced, so that the cleaning operation can be performed efficiently even in a wide work space in the factory. Therefore, since the number of installed air purifiers 1 can be reduced, it can be installed without requiring an excessive installation space even in a factory where devices such as manufacturing and processing lines are rationally arranged. In addition, by reducing the number of facilities of the air cleaning device 1, the facility cost can be greatly reduced.

  Further, due to a decrease in the cleaning ability of the filter Fa wound around the outer peripheral surface 21 of the main body 10, an unused portion of the filter Fa is pulled out from the roll filter F accommodated in the main body 10 and is applied to the outer peripheral surface 21 of the main body 10. In the case of winding, the first filter feed roller 59a, the second filter feed roller 59b, the third filter feed roller 59c, and the fourth filter follow the pull-out of the filter Fa from the roll filter F held in the main body 10. Smooth feed and guidance of the filter Fa are realized by the rotation of the feed roller 59d, and unused portions of the filter Fa can be easily pulled out and wound.
