Abstract

PURPOSE:To manufacture a mist filter of high performance without bias cutting or bonding by providing a number of sheets continuing from inlet side through outlet side in parallel and forming flex cylindrical holes between each pair of sheets. CONSTITUTION:A mist filter 5 is formed by providing saw-toothed flexing adhesive 2 in plural lines at a fixed interval on one face of a paper plate 1, bonding a number of piled paper plates and leaving non-adhered sections not bonded. As shown in the sketch, said mist filter 5 uses its right side as the inlet side 6 and left side as the outlet side 7, and each of paper plates 1 continues from inlet side 6 through outlet side 7. The angle of inclination of a flex cylindrical hole 4 is decided by considering the face of opening 4a and the width from inlet side 6 to outlet side 7, and formed in such a way that mist coming in as chain line 8 hits against the inner wall of the flex cylindrical hole 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a Miss 1 filter and a method for manufacturing the same, and is used in the field of air cleaning equipment.

(Conventional technology) Conventionally, air purification in painting booths, etc.]! l! Mist filters are used for purposes such as removing oil from oil vapor in the field.

This mist filter uses a multi-layer structure of pressed metal or palm rock, or a honeycomb core or roll core with a bent cylindrical hole, but it has a high filtering capacity. For this reason, materials using honeycomb cores or roll cores are often used.

(Problem to be Solved by the Invention) A mist filter using a honeycomb core or a roll core is, for example, two honeycomb cores connected with the cylindrical holes formed in each core at an angle (for example, 90 degrees). Since it was constructed by joining them so that they could communicate (Utility Model Application No. 57-95220), the end face where the cylindrical hole of the honeycomb core opens was
It was necessary to make a 5 degree bevel cut and join the beveled end faces to each other. Therefore, in manufacturing, it requires many man-hours to form the beveled end faces and to join the beveled end faces, and the work is relatively difficult and requires a lot of skill.

(Means for Solving the Problems) The mist filter of the present invention has a large number of continuous sheets arranged in parallel from the entrance side to the exit side, and a bent cylindrical hole is formed between each sheet. It is characterized by

The sheet may be a paper board, a synthetic resin board, a thin metal board, or the like, and is selected depending on the components of the mist, the temperature, etc. Incidentally, the cylindrical holes may be independent from adjacent cylindrical holes or may be communicated with each other through bent portions.

However, the above-mentioned mist filter is a polymerized mist filter obtained by bending a plurality of rows of adhesive at a predetermined interval on a predetermined surface of a sheet, stacking a large number of the sheets, and adhering adjacent sheets to each other via the adhesive. It is manufactured by cutting a sheet to a predetermined size and separating the non-adhered portions of adjacent sheets from each other to form a bent cylindrical hole.

In the above, if the adhesive is placed along a continuous bending line, an independent bent tube hole will be obtained, whereas if it is placed along a discontinuous bending line, a bent tube that connects adjacent tube holes will be obtained. A hole is obtained.

The adhesive may be provided only on one surface of the sheet or on both surfaces of the sheet.

(Function) The mist filter of the present invention and its manufacturing method have a structure in which there is no joining part in the middle part as described above, so it can be used as a mist filter with a conventional honeycomb core etc. without the need for diagonal cutting or joining work. You will get something equivalent.

(Example) Examples of the present invention will be described below. First, the manufacturing method will be explained as shown in FIGS. 1 to 3. That is, the adhesive 2 is bent into a sawtooth shape on one side of a paper board 1 and provided in multiple rows at predetermined intervals, and a large number of paper boards 1 are formed as shown in Fig. 2 (the figure shows the case of 8 sheets). Adjacent paper boards are stacked and adhered to each other with an adhesive 2. Next, the polymerized paper board 3
is cut into a predetermined size as shown by the chain line, and the outermost sides of the overlapping paper board 3 are separated from each other to separate the non-adhered portions of adjacent paper boards in the overlapping paper board 3 to form a bent cylindrical hole 4. Thus, the mist filter 5 is completed.

As shown in FIG. 4, the mist filter 5 is placed on the - side (
The right side) is used as the entrance side 6, and the other side (left side) is used as the exit side 7, and each paper &1 has a structure in which the distance from the entrance side 6 to the exit side 7 is 1R.

The inclination angle of the bent tube hole 4 is determined by taking into account the size of the opening 4a of the bent tube hole 4 and the width from the inlet side 6 to the outlet side 7, so that the mist flowing in as shown by the chain line 8 flows into the bent tube. What is necessary is just to form it so that it may collide with the inner wall of the hole 4. Also, the number of bends does not necessarily have to form a three-dimensional shape as shown in the figure;
It may be set at a value greater than or equal to Mita, and may be adjusted as appropriate depending on the components of the target mist and their amounts.

5 and 6 show other embodiments of the invention, in which a paper board 1
The adhesive 2 provided on one surface of the adhesive 2 is discontinuously applied along the serrated bending lines, and is manufactured in the same manner as described above.

In this case, as shown in FIG. 6, the paper board 1 is continuous from the inlet side 6 to the outlet side 7, while the bent cylindrical hole 4 formed between the many paper boards is connected to the adjacent bent part at the bent part. The structure is such that they communicate with each other via the cylindrical hole 4 and the communication hole 9.

FIG. 7 shows a painting equipment using the mist filter 5 of the present invention. In the figure, 10 is a painting booth, 11 is a taxiway, 1
2 is an exhaust fan, and the mist filter 5.5 is installed inside the painting booth 10. In this painting equipment, when a painting operation is performed in front of the mist filter 5.5, the mist containing paint particles is sucked in by the fan as shown by arrow 13, and as it passes through the mist filter 5.5, the mist is The paint particles inside can be filtered by adhering to the inner wall of the bent tube hole 4, and air not containing paint particles can be discharged to the outside.

In the above embodiment, the adhesive 2 was provided on one side of the paper board 1, but it may also be provided on both sides in the same way so that the adhesive 2 is bonded to each other when the paper board 1.1 is polymerized. can.

(Effects of the Invention) As explained above, according to the present invention, there is an effect that a mist filter with high filtering ability can be easily manufactured.
