Description

  The present invention relates to a building having an oil mist generation source, and more particularly to a building that has been provided with an oil mist removal measure.

  In metal processing such as cutting, oil is constantly flowed in order to suppress heat generation due to processing of a metal that is a workpiece. The processing machine 21 that performs metal processing using such oil generates a so-called “oil mist”, but a building that can maintain a certain degree of hermeticity in order to prevent the oil mist from being discharged to the outside. It is common to install in (factory).

  Oil mist is scattered from the processing machine 21 in the building, but if it is left scattered, it will not only be harmful to the human body, but will also condense and adhere to the floor and walls. Must be done. In particular, since oil mist is in the form of a relatively heavy mist, it is likely to float on the lower side of the building and adhere to the floor, and is difficult to remove with an exhaust fan provided on the ceiling.

  Various types of oil mist removing devices have been proposed in Patent Documents 1 to 3 and the like.

  As shown in FIG. 4, the “oil mist recirculation method and its oil mist control system” proposed in Patent Document 1 is “oil mist recirculation by a factory machine and a mist collector in the vicinity thereof. The method is a structure in which a suction hose and a discharge hose are connected between the machine and the mist collector, and an exhaust hose is provided to the discharge hose via a switching valve. Oil mist that guides contaminated air to the mist collector with a suction hose, circulates clean air to the machine with a discharge hose under control of the switching means, and guides clean air to a filter / exhaust hose with control of the switching means It is a thing of the structure of "it is a recirculation method."

  According to the “circulation method of oil mist” of Patent Document 1, “a small and economical mist collector is used for the treatment of oil mist generated from a machine. This mist collector is simply an oil mist collector. This structure separates the mist and reuses the separated oil, so the mist diffuses when the closed chamber is opened by taking out the processed parts or carrying in the processed materials, and the air inside and outside the factory is debris. It may be possible to solve problems such as “contamination with mist and / or mists, and adverse effects such as causing deterioration of the work environment”, but if the air in the entire building is to be purified, it will be installed. Therefore, this method must be adopted for each processing machine 21, and it is considered that the factory equipment cost increases.

  As shown in FIG. 5, the “circulation type dust collector” described in Patent Document 2 is an “air curtain flow that swirls around the oil mist component generation sources 3, 4, and 7 downward from above. F1 is formed, and an intake swirl flow F2 that rises while swirling from below to above is formed inside, and the oil mist components OM and the like generated from the oil mist component generation sources 3, 4, and 7 are sucked. The grease filter 16 that collects and liquefies the sucked oil mist component collects and liquefies the oil component that is collected and discharged to the oil reservoir 26 ".

  The “circulation type dust collector” described in Patent Document 2 collects oil mist components generated in a machining factory or the like at high efficiency and low cost without requiring an exhaust duct facility or the like to the outside. Providing a circulating dust collector that can be recovered "is considered to be possible, but it is considered that a very large space is required to form" air curtain flow F ". Even in the dust collector of Document 2, it is considered that the cost of factory equipment is increased.

  On the other hand, as shown in FIG. 6, the “gas cleaning device” described in Patent Document 3 is “a fibrous body 16 that is skewed with a gas flow in the gas flow path 2 and that has a tip directed downward. Are arranged in a plurality of rows and stages with respect to the gas flow, between droplets spraying means 17 for spraying droplets toward the fibrous body 16 and between the fibrous bodies 16 by introducing a cleaning gas into the gas flow path 2. The gas flow means 5 for allowing the gas to pass through is effectively removed by the fibrous body to which the droplets adhere, and the droplets containing the dust move smoothly without staying in the fibrous body. , Dripping to prevent clogging of the fibrous material for a long period of time, reducing maintenance and replacement work, removing fine dust and oil mist, deodorizing, polluting gas with a fibrous body arranged in multiple rows and multiple rows Can be removed ".

  In the “gas cleaning device” described in this Patent Document 3, “when cleaning the air for the purpose of improving the factory environment, etc., it is effective to remove dust, odor, polluting gas, etc. without causing clogging of the filter. However, even with the gas cleaning device disclosed in Patent Document 3, it is considered that the cost of factory equipment increases.

Above all, with the techniques of Patent Documents 1 to 3 above, the local removal of oil mist can be performed with a great effect, but it seems that the entire factory cannot be removed. If oil mist leaks from the equipment and scatters in parts other than the above purification facilities in the factory, it is not difficult to imagine that this oil mist will contaminate the walls and ceiling.

  Accordingly, the present inventors have conducted various studies on how to remove oil mist without increasing the plant equipment cost so much, and as a result, swept away relatively heavy oil mist by the flow of air. The present invention has been completed.

  In other words, the object of the present invention is to allow the air containing oil mist to be taken out of the building while introducing the outside air into the entire interior, so that the inside air can always be kept clean and the equipment cost is also increased. It is to provide a building that does not cost much.

In order to solve the above problems, the means taken by the present invention will be described with reference numerals used in the description of the best mode to be described later.
“A building 10 having a processing machine 21 that is a source of oil mist 20 and having an opening / closing window 30 through which outside air can be introduced,
The window opening and closing device 11 that opens and closes the opening and closing window 30, the fan 12 that discharges air including the oil mist 20 in the building 10 to the outside, and the fan 12 and the window opening and closing device 11 are associated and controlled. A control device 13;
When the control device 13 detects a predetermined amount of the oil mist 20 in the air or measures a preset time, the window opening / closing device 11 and the fan 12 are driven and the opening / closing window 30 The building 10 is characterized in that outside air is introduced into the building 10 and the oil mist 20 in the building 10 is discharged from the fan 12 to the outside.
It is.

  That is, the building 10 according to the present invention first has an opening / closing window 30 in which a processing machine 21 as a generation source of the oil mist 20 is installed and an outside air can be introduced as shown in FIGS. The opening / closing window 30 is opened / closed by the window opening / closing device 11. Note that it is not necessary that all the opening / closing windows 30 of the building 10 can be opened / closed by the window opening / closing device 11, and it is sufficient to target the opening / closing windows 30 in a place where outside air can be easily introduced. .

  Further, as shown in FIGS. 1 and 2, the building 10 associates the fan 12 that discharges air including the oil mist 20 in the building 10 to the outside, and the fan 12 and the window opening and closing device 11. And a control device 13 for driving and controlling. Driving and controlling the fan 12 and the window opening / closing device 11 in association with each other means that the operation timing or stop timing of the window opening / closing device 11 and the fan 12 is set to a slight time, or at the same time.

  The control device 13 drives the window opening and closing device 11 and the fan 12 when detecting a predetermined amount of the oil mist 20 in the air or measuring a preset time. When the opening / closing window 30 is opened as shown in FIG. 1 by driving, external air is introduced into the building 10 from the opened opening / closing window 30. Moreover, when the fan 12 is operated by the control device 13, the oil mist 20 in the building 10 is discharged from the fan 12 to the outside.

  Of course, when the window opening / closing device 11 is driven to close the opening / closing window 30 and the fan 12 is stopped, the air in the building 10 does not move and remains quiet as shown in FIG.

  As described above, in the building 10 according to the present invention, when the control device 13 detects a predetermined amount of the oil mist 20 in the air or measures a preset time, the window is opened and closed. The device 11 and the fan 12 are driven to introduce outside air into the building 10 through the opening / closing window 30, and the oil mist 20 in the building 10 is discharged from the fan 12 to the outside, which may adversely affect the human body. The oil mist 20 that causes the walls and ceiling to become dirty does not stay in the building 10.

  In particular, since the general opening / closing window 30 is generally provided at a position where a person standing on the floor can also open / close, the outside air flowing in from the opened opening / closing window 30 uses the air below the inside of the building 10 as a fan. It will act so that it will flow toward 12. At this time, the relatively heavy oil mist 20 sinks downward in the building 10 and is mainly contained in the air swept away by the outside air. Therefore, by introducing the outside air as described above, Most of the air is discharged to the outside by the fan 12 of the building 10.

  In other words, most of the relatively heavy oil mist 20 is discharged to the outside by the fan 12 of the building 10 if the outside air flowing in from the opened opening / closing window 30 is used. There is no need to use a large-scale device as proposed in the above.

  Further, in order to make an existing building into the building 10 according to the present invention, a window opening / closing device 11 is attached to the opening / closing window 30, and the fan 12 that would be originally provided in the existing building 10 is attached to the window opening / closing device 11. At the same time, it can be performed only by electrically connecting to the control device 13, and the building 10 according to the present invention can be performed without causing a large increase in the equipment cost. In this case, it does not matter how much the processing machine 21 that is the source of the oil mist 20 is present, and no matter how the volume of the building 10 is, the control device 13 uses the opening / closing window 30. By setting the opening time and the operating time of the fan 12, it can be easily dealt with.

  Therefore, the building 10 according to the present invention can discharge the air containing the oil mist 20 to the outside of the building 10 while introducing the outside air to the entire inside, and can keep the inside air always clean. Is not so much.

As described above, in the present invention,
“A building 10 having a processing machine 21 that is a source of oil mist 20 and having an opening / closing window 30 through which outside air can be introduced,
