Description

  The present invention relates to a filter device that is disposed in front of an air conditioner used in a factory or the like and removes oil dust and ash dust.

  For example, in a factory that performs casting, plating, painting, etc. of metal parts, oil dust and ash dust containing various types of chemical elements are generated during the product manufacturing process, so the front of air conditioning equipment (air conditioners, etc.) A filter device for capturing oil dust and ash dust contained in the air exhausted from the air conditioning equipment is installed.

  There are various types of filter devices. One form of the filter device is a filter roll on which a filter sheet before use is wound, another filter roll on which a filter sheet after use is wound, The filter sheet extending from the filter roll around which the filter sheet is wound is in a folding position where the filter sheet is folded back, and the filter sheet (filter sheet after use) which is folded back is sent to another filter roll. An apparatus for moving the filter sheet between the filter rolls can be mentioned.

  The filter sheet before use straddling between the two filter rolls is placed in front of the exhaust port of the air conditioning equipment, the air conditioning equipment is operated for a certain period of time, and oil and ash dust adhere to the filter sheet before use. At a stage where the function is not achieved, for example, the filter roll for winding the used filter sheet is rotated to move the filter sheet. By this movement of the filter sheet, the used filter sheet is wound around the filter roll, and a new filter sheet before use is sent out and arranged on the front surface of the exhaust port of the air conditioning equipment.

  In this filter device, the filter sheet before use in the wound state can be easily installed on the filter roll, and the used filter sheet wound and collected on a separate filter roll can be easily removed from the filter roll. Can be removed and discarded.

  However, there is a sufficient possibility that captured matter such as oil dust and ash dust will be peeled off from the used filter sheet wound and collected on the filter roll, and it is necessary to prevent the captured material that has fallen off from being scattered or captured There is a problem that it may be necessary to clean things.

  Here, the prior art regarding the filter device is disclosed in Patent Documents 1 to 3.

  Patent Document 1 discloses a device for removing a solid substance in a gas, in which a roll-like coarse dust filter is bent so as to have a constant interval and configured in a plurality of stages.

  On the other hand, Patent Document 2 includes a filter net, a support shaft, a bearing sheet, a take-up shaft, a box sheet, and a motor. A bearing sheet is pivotally provided at both ends of the support shaft, and two bearing sheets are appropriately placed in the box sheet. The filter nets are hung in an S-curve shape, with support shafts arranged at a certain distance, installed at a height corresponding to the bearing seats fixed on the inner surfaces facing each other, and parallelly provided on both sides vertically. An exhaust treatment device is disclosed in which both sides of a net exhibit an intersecting state to absorb oil dust, and both sides of the net hole circulating along the S orbit adhere ash dust completely in the hole.

  Further, Patent Document 3 describes a zigzag filter that is guided by the rotor group and captures dust in the air of the air conditioning system, and all the rotors of the upstream rotor group in the air flow in the rotor group. A support structure for an automatic winding filter is disclosed which includes a drive source for rotating all the rotors of the rotor group on the downstream side via the chain and the chain.

  According to the solid substance removing device disclosed in Patent Document 1, it is possible to reduce the cost without reducing the work efficiency. Further, according to the exhaust treatment device disclosed in Patent Document 2, the adhesion area of ash dust increases, and reliable purification can be achieved. Furthermore, according to the support structure of the automatic winding filter disclosed in Patent Document 3, the filter is hardly subjected to the tensile force from the winding portion, and therefore any filter can be wound regardless of the strength of the filter medium. Furthermore, the filter area can be changed simply by changing the length of the chain and the position of the rotor, and the degree of freedom in filter design can be increased.

  However, even with these solid matter removing devices, the above-mentioned problem, that is, the captured matter such as oil dust and ash dust is peeled off from the used filter sheet wound and collected on the filter roll, and the separated captured matter is scattered. It is not possible to solve the problem that it may be necessary to prevent the cleaning and the trapped object to be scattered.

  The present invention has been made in view of the above-described problems, and can effectively eliminate the capture of oil dust and ash dust from the used filter sheet wound and collected on a filter roll. An object is to provide an apparatus.

  In order to achieve the above object, a filter device according to the present invention includes a first filter roll wound in a state where a filter sheet before use and a protective sheet are laminated, and a filter sheet after use. A second filter roll, a third filter roll that is in a folded position where the filter sheet extending from the first filter roll is folded, and sends the folded filter sheet to the second filter roll; and A peeling member that peels off the protective sheet from the moving filter sheet, guides the peeled protective sheet to the second filter roll, and is used after being wound around the second filter roll. And a guide member that guides the outside of the sheet.

  The filter device according to the present invention includes a peeling member that peels off the protective sheet laminated on the filter sheet before use from the filter sheet before use in the process of moving the filter sheet and the protective sheet, and a filter roll. It is characterized in that it has a guide member for guiding the protective sheet peeled off the outside of the used filter wound and collected.

  Here, the “filter sheet before use” is a filter sheet before capturing captured matter such as oil dust and ash dust contained in the air exhausted from the air conditioning equipment, and “filter sheet after use”. "Means a sheet that has captured the trapped substance and has not been able to sufficiently perform the filter function due to the large number of trapped trapped substances. Further, the “folded filter sheet” means a filter sheet between the second and third filter rolls and “filter sheet after use”. Strictly speaking, the filter sheet between the first and third filter rolls is a “filter sheet before use” before the captured matter adheres to the sheet, and “use” in the state where the captured matter adheres. It becomes a “filter sheet after”. Therefore, the filter sheet between the first and third filter rolls changes from the one before use to the one after use due to temporal changes.

  The first filter roll wound in a state where the filter sheet before use and the protective sheet are laminated and the second filter roll wound with the filter sheet after use are, for example, approximately the same at an interval. It is good to arrange | position in the height position. This is because, as will be described later, the protective sheet peeled off by the peeling member can be guided in the horizontal direction.

  On the other hand, the third filter roll is disposed at a predetermined height higher than the first and second filter rolls, and the filter sheet extending from the first filter roll is folded back by the third filter roll. It extends to the second filter roll and is wound and collected here.

  A pre-use filter sheet between the first and third filter rolls is installed on the front surface of the exhaust port of the air conditioning equipment, and oil dust and ash dust contained in the air exhausted from the exhaust port are captured here.

  For example, a handle or a drive motor that is manually rotated by an operator is attached to the second filter roll, and the second filter roll is rotated by rotating the handle or driving the drive motor. The filter sheet moves. That is, the used filter sheet between the second and third filter rolls is wound and collected on the second filter roll, and the first, changed from the pre-use state to the post-use state due to the attachment of the captured matter. The filter sheet located between the third filter rolls is folded back by the second filter roll and moves between the second and third filter rolls. Further, with the movement of the filter sheet between the first and third filter rolls, the filter sheet before use and the protective sheet wound around the first filter roll are laminated to the third filter roll side. Pulled out.

  When the filter sheet and the protective sheet before use are pulled out to the third filter roll side in a laminated state, a peeling member located near the first filter roll is interposed between the filter sheet and the protective sheet, When the protective sheet passes through the peeling member, the protective sheet is peeled off from the filter sheet.

  The protective sheet peeled off from the filter sheet is guided and sent to the second filter roll side by the guide member. Here, examples of the “guide member” include a plurality of roll members arranged at intervals from the vicinity of the peeling member to the second filter roll, and further to the outer periphery of the second filter roll. .

  On the other hand, the filter sheet before use from which the protective sheet has been peeled is sent to the third filter roll side, and is disposed between the first and third filter rolls (in front of the exhaust port of the air conditioning equipment).

  The protective sheet peeled off from the filter sheet is guided to the second filter roll side by the guide member, and is guided to the outer periphery of the used filter sheet wound and collected by the second filter roll.

  The protective sheet guided by the outer periphery of the used filter sheet wound and collected by the second filter roll surrounds the used filter sheet, and the used filter sheet is surrounded by the protective sheet. Captured materials such as oil dust and ash dust are peeled off from the sheet, and scattering of the separated captured materials can be suppressed.

  As can be understood from the above description, according to the filter device of the present invention, the protective sheet laminated on the filter sheet before use is peeled off from the filter sheet before use in the process of moving the filter sheet and the protective sheet. The protective sheet surrounds the used filter sheet by guiding the protective sheet peeled off on the outside of the used filter sheet wound and collected on the second filter roll by the guide member. It is possible to prevent the captured matter such as oil dust and ash dust from being peeled off from the filter sheet after use and scattering of the captured material that has been peeled off.
