Abstract

PURPOSE:To sufficiently clean off the activated carbon defectively bonded or protruding from the surface of a substrate with a rubbing machine by conveying an activated carbon carrying latticed substrate by both delivery roller couples between a couple of rotating filing belts in the system for producing a deodorizing filter. CONSTITUTION:An activated carbon carrying latticed substrate 12 is conveyed by the driving roller 272 and driven roller 274 on the inlet side and the driving roller 276 and driven roller 278 on the outlet side in the rubbing mechanism 62. Endless filing belts 288 and 298 are vertically arranged with the substrate 12 between both roller couples. The belts 288 and 298 are laid between the driving roller 282 with the length adjustable and driven roller 286 and between the driving roller 292 and driven roller 296. The belts 288 and 298 are rotated in the direction of the arrow at a speed considerably higher than the traveling speed of the substrate 12. Consequently, the activated carbon protruding from the upper and lower surfaces of the substrate 12 is rubbed off, and the activated carbon weakly stuck to the substrate 12 is released by the vibrated substrate 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning device for a grid-like substrate impregnated with activated carbon, and particularly to a deodorizing filter for a near conditioner comprising a filter substrate and activated carbon particles adhered to the filter substrate. The present invention relates to an apparatus for cleaning the grid-like substrate after impregnation with activated carbon in a manufacturing system.

[Prior Art] In Japanese Patent Application No. 258,748, the applicant of the present invention has proposed a filter consisting of a lattice-shaped filter base and gas adsorbent (mainly activated carbon) particles adhered to the filter base. This filter has a thickness of about 151 nm for the base.
m or less, the planar area of one cell of the lattice of the substrate - about 0.20 - about 0.35 cn2, the size of the gas absorbent particles in J2 - about 20 - about 60 mesh, per unit area of the plane of the substrate. Amount of gas absorbent particles used - approx. 400 approx. 2000 g/m
2. The filter is characterized in that the condition of the aperture ratio of this filter is approximately 50% to approximately 80%.

In summary, this filter differs from conventional filters in that the activated carbon (gas adsorbent) particle shear is relatively large and the filter thickness is small.

Therefore, special consideration is required in handling the filter base, impregnation of ll'i carbon, etc., which is different from that of conventional products.

[Problems to be Solved by the Invention] Since the activated carbon-added 100-lattice substrate (filter) to be treated in the present invention has large particles of activated carbon, activated carbon that is not in a good adhesion state tends to fall off. In particular, the activated carbon protruding from both surfaces of the filter (the periphery of the lattice openings in the base) easily falls off. This is highly undesirable in applications such as deodorizing filters for near conditioners. Therefore, activated carbon with poor adhesion or protrusions from the surface
Activated carbon must be thoroughly cleaned before it can be used as a filter or primary product.

The present invention has been made based on this viewpoint, and
The purpose of this invention is to provide a device for cleaning a grid-like substrate after aromatic carbon addition.

[Means for Solving the Problems] In order to achieve the above-mentioned objective 1, the apparatus of the present invention includes an inlet feed roller pair and an outlet feed roller pair that convey the lattice-like substrate to which activated carbon is attached, and both of the above. a rotating file heald of 1'bj provided between the pair of feed rollers and facing each other with the base body in between so as to be in contact with each surface on both sides of the base body;
, a part for rotating the belt in a forward direction with respect to the conveying direction of the substrate.

In a desirable embodiment, the file heald is stretched between a driving roller and a driven roller, and the driving roller and the driven roller are provided so that they can approach and separate from each other, and the driven roller is attached to the base body. Forced. Also,"
- An operating lever for bringing the driven roller closer to the driving roller is provided. Further, a vibrating sieve is disposed next to the pair of exit rollers [Function] According to the device according to the present invention having the above configuration, the lattice-shaped U body to which the activated carbon is attached is placed between the two feed rollers. With no bridge between the pairs, the surfaces on both sides are polished as if they were sandwiched between the old rotating rasp Peruvian pairs.

The file belt can be replaced by temporarily reducing the distance between the drive roller and the driven roller by operating a lever.

[Example] Filter structure and abrasive structure FIG. 2 is a plan view showing an example of a deodorizing filter 0 processed by the apparatus according to the present invention. This filter consists of a grid-like filter base 12 and gas adsorbent particles 14 adhered to the filter base 12.

The deodorizing filter IO has an aperture ratio (in the plane 51 parallel to the paper plane of FIG. 2) of about 50 to about 80%, and this value is obtained as a result of complying with various conditions described below. Also, the thickness of the filter IO (in the direction perpendicular to the paper surface of Fig. 2)
is 1. ! onm or less, preferably about 3 mm or more. As shown in FIG.
It differs from traditional filters in that it is thinner and smaller. These characteristics are the key to satisfying the requirements of low pressure loss, appropriate deodorizing ability, and long life as a deodorizing filter for near conditioners.

The base 12 is made of a thin material such as paper, aluminum, or plastic. When paper is used as the +A material, the strength can be reinforced by impregnating it with phenol resin or the like. Further, the base body 12 can also be subjected to a non-combustible treatment. base j2
Since the thickness of 19 is substantially the thickness of the present filter 10,
It is about 15 mm or less, preferably 3 Tl1 m or more. This thickness is determined because the present filter 0 is finally housed in the casing of the near conditioner.

In the illustrated example, the pattern shape of the lattice of the base body 12 is a hexagonal so-called honeycomb shape, but the pattern shape can be any shape such as a rectangle or a triangle. However, the planar area of one cell 16 of the grid (second
) is approximately 0.20-
It will be about 0.35 cm2. This value essentially means the density of the partition wall I8 for supporting the gas adsorbent particles 14.

The dregs adsorbent particles 14 are made of activated carbon, but other types such as impregnated activated carbon can also be used. Further, in order to deal with indoor CO generation sources such as oil stoves, a catalyst capable of catalytically oxidizing CO can be used in combination with a deodorizer. This catalyst is a gold/oxide catalyst that does not become inactive even in the presence of moisture (disclosed in Japanese Patent Application Laid-Open No. 60-238148, etc.).
or desirable. The old method of scum adsorbent particles 14 is about 20 to about 6
The amount of gas adsorbent particles 14 used per plane unit area of the base 12 is about 400 to about 2DOOg/m.
It is 2.

As the binder for attaching the dregs adsorbent particles 14 to the substrate 12, an adhesive is preferably used to prevent the particles from falling off. Acrylic-based, natural rubber-based, synthetic rubber-based, and silicone thread rings can be used as the adhesive, but in order to strongly adhere to the filter base so that the activated carbon does not fall off, a highly concentrated adhesive is required. In addition, it is required that the layer thickness be increased to some extent. Therefore,
The thickener liquid used has a high viscosity (approximately 10 to 50 poise)
Therefore, the coating method must be such that a thick layer can be obtained.

Overall view of the manufacturing system FIG. 3 is a top view showing an example of the entire manufacturing system for a deodorizing filter for an air conditioner, which incorporates the cleaning device according to the present invention.

At the inlet of the system, an inlet is formed for introducing the unexpanded filter substrate, ie, the filter substrate in the lattice or collapsed state, into the system.

With this system, unexpanded 1A material blocks can be introduced and processed as they are, making it possible to reduce the effort and cost involved in transporting and storing old materials.

In the introduction section, there is a free roller conveyor (introduction machine) 22.2
3 are arranged, and these continuously introduce the base body] 2 in a direction parallel to the paper plane of FIG. A spreading machine 24 is installed in the middle of the conveyors 22, 23, which spreads the substrates, ie opens the grid, by the action of moisture and heat. Following the conveyor 23, a pin conveyor 26 is arranged, which conveys the substrate by hooking pins on a grid of the stretched substrate.

Following the conveyor 26, high viscosity viscosity is applied to the expanded substrate.
A pickling machine 28 for supplying the Z agent is also provided. Soaking machine 2
No. 8 is of a type in which the substrate 1-2 is forcibly immersed in a high viscosity (approximately 10 to 50 voids) adhesive bath to form a thick adhesive layer over the entire area of the substrate. At this time, since the adhesive has a high viscosity, it is thought that a film is often applied within the grid. Therefore, if the filter is allowed to dry as it is, it will cause an increase in pressure loss, a decrease in deodorizing performance, and a shortened service life of the finished filter. In order to avoid this, in this system, a blower 32 that removes excess adhesive with air is disposed after the dipping machine 28. Since the adhesive has a high viscosity, the wind speed of the air hitting the adhesive is quite high (approximately 30-250
m/sec) is desirable.

A pin conveyor 34 similar to the conveyor 26 is arranged after the blower 32, which transfers the substrate 12 to the pin conveyor of the next dryer 36. ” Since the system shown in the figure is a new base + A material diblock, when using a new base + A material diblock, manually press until the grid at the tip of the base hangs over the pins of the pin conveyor of the dryer 36. The old base material will be introduced from the entrance side.

The dryer 36 heats the substrate 2 to reduce the moisture content of the sticky S agent applied to the substrate to a predetermined amount. This imparts a predetermined viscosity to the adhesive and removes the odor of the solvent.

- For boat fishing, the initial moisture content of the adhesive is about 70% by weight, and this is reduced to 10% by weight or less, preferably about 3% by weight, at the mouth of the dryer 36.

In addition, the thicker the adhesive coating layer, the more likely it is that foaming will occur during the drying process.
100°C) over a long period of time (about 10 to 30 minutes).

After drying, the substrate 12 is cut to size for the finished air conditioner filter. Since the adhesive or dried substrate itself has considerable strength, it is possible to cut it accurately. Furthermore, cutting before impregnating activated carbon has the advantage of extending the life of the cutting blade. However, it is also possible to cut the substrate after applying the activated carbon.

More specifically, a first cutting machine 38 is installed at the outlet of the dryer 36, and this cuts the substrate 2 in a direction perpendicularly transverse to the longitudinal axis from the conveyor 22 to the dryer 36. . Following this, a direction changing mechanism 44 is disposed, and the substrate 12 cut by the cutter 38 is transferred to a roller conveyor 4.
2 to a roller conveyor 46 in a conveying direction perpendicular to this. At the end of the conveyor 46, a second cutting machine 48 is installed.
The substrate 2 is cut in a direction perpendicularly transverse to the longitudinal axis of the conveyor 46, and the substrate has the above-mentioned predetermined dimensions.

Following the second cutting machine 48, an impregnating machine 54 is disposed to apply activated carbon to the substrate 12 of a predetermined size via the adhesive. The applicator 54 advances the base body 12 by means of a vibrating conveyor mechanism that constitutes its bottom wall. On the side of the applicator 54,
For the impregnating machine 54, an activated carbon feeder 52 is provided for supplying the activated carbon toward the base 12 so that it falls from one direction.

A) A sieve unit 56 is installed at the rear of the machine 54 to remove a portion of the final 1q charcoal.

At the outlet of the applicator 54, a belt conveyor 58 is arranged at right angles to the conveyor 44. At the end of the conveyor 58, a T-sifter 62 (for removing part of the activated carbon by friction) is installed, and a vibrating sieve 64 is installed after that.

The activated carbon attached to the base 12 includes one that is firmly bonded to the base! There are some products with Bi <('I' W. Activated carbon that is weakly attached may easily fall off due to subsequent contact, vibration, etc., and may stain the physical environment. It is desirable that the particles fall off during the process.There are several ways to do this, such as using the impact force of a vibrating container, using centrifugal force, or using friction with a plan or coarse-grained file cap. Alternatively, it is possible to arbitrarily select a plurality of activated carbons.In the illustrated system, the sieving unit 56 and the sieving machine 64 remove unnecessary activated carbon by the impact force of the vibrating conveyor, and the friction machine 62 removes unnecessary activated carbon by the rotational frictional force of the shear. let

Following the sieving machine 64, a packaging section 66 in a known manner is arranged. The filter base from which unnecessary activated carbon has been removed is now used as a deodorizing filter for a completed air conditioner.
(The finished filter is packed in a bag, corrugated hole, or a combination of these in a form suitable for one load. At this point, the completed filter is wrapped with ventilation material such as non-woven fabric or netting using means such as heat-sealing. However, the appearance and quality can also be improved.

Cleaning Apparatus FIG. 1 is a schematic side view showing a main part of a friction machine 62 in a cleaning apparatus according to the present invention.

In the friction machine 62, the base 12 is connected to the inlet drive roller 2.
72 and a driven roller 274, an exit side drive roller 276, and a driven roller 278. Between both roller pairs, there is an endless file bell (2) with the substrate 16 in between.
88,298 are arranged. The belt 288 has a length W]
A drive roller 282, which is pivotally supported at both ends of an adjustable frame mechanism 284;
is stretched between a driving roller 292 and a driven roller 296 that are pivotally supported at both ends of a frame mechanism 294 whose length is adjustable. The drive roller 282 is driven by a motor 283 supported by a common frame 281, and the drive roller 292 is driven by a motor 293 supported by a common frame 291.

Both belts 288 and 298 rotate in the direction of the arrow in the figure at a much higher speed than the conveyance speed of the substrate 12.

As a result, the activated carbon protruding below the substrate]2 is scraped off by friction, and the vibration applied to the substrate at this time causes the activated carbon that is weakly
11 Release. The rotation direction of both belts 288 and 298 is
The forward direction is defined as the direction in which the base body 12 is transported. If it is in the opposite direction, it will be difficult for the base 12 to enter between the bells 1-288 and 298.

FIG. 4 is a front view of the friction machine 62 with the file belts 288, 298 removed. Frame mechanism 2 of friction machine 62
84.294 are basically the same in structure, only the lower mechanism +hS 284 will be shown and explained in detail in FIG. 4, and the upper mechanism 294 will be omitted.

As shown in FIG. 4, a beam 114 extends horizontally from the column 112 of the rubbing machine 62, and a frame 281 for a drive roller 282 and a motor 283 is fixed to the beam 114. On the other hand, in the center of the shaft support frame 22 of the driven roller 286, a shaft)-1, 24 is provided extending downwardly, and this is a longitudinal bushing arranged upwardly perpendicularly to the beam 1]4'2. ]8. A compression coil spring 126 is interposed between the bush 118 and the frame 122, with the shaft coil 24 wound around it.

A reinforcing plate 116 is also fixed to the beam 114, and a pivot lever 32 is pivotally supported at the end of the reinforcing plate 116.

A coil spring [34] is attached to the lever 132, and the other end thereof is a plate piece that has been sunk into the frame 122].
28.

A guide plate 142 is also provided on the frame 122 and extends vertically downward. A long hole 44 is formed in the lower part of the temporary kite 142, and a pin 146 installed in the reinforcing bell 116 engages with the Jk hole 44.

Due to the structure described above, the driven roller 286 is biased 4=j towards the base body 12 by the spring 126, thus ensuring good contact between the file bell I-288 and the base body 12 (first (see figure). This NI force is regulated by a coil spring installed between the lever 132 and the plate 1'+128] 34, and a kite plate 142 installed between the reinforcing plate 16 and the frame 22.

The lever 132 is also used when replacing the file heald 288. That is, when the lever 132 is turned in the forward direction in FIG. 4, the driven roller 286 is moved toward the driving roller 282 against the angular force of the spring 1-26. Therefore, if the tension of the file bell l-288 becomes loose, it becomes easy to replace it.

FIG. 5 is an enlarged schematic side view showing the sieving machine 64 disposed immediately after the friction machine 62. Sieve] 6 The machine 64 has basically the same structure as the sieve part 56 of the impregnating machine 54, and brushes off the 'li'+ carbon by the impact force of the vibrating conveyor.

In the center of the trough 302 of the sieving machine 64, an IO mesh wire mesh 312 is arranged, over which the substrate passes. On both side walls 304 of the lower bulging part of the trough 302, an applicator 54 is installed.
A vibrator 306 similar to the above is installed, and the trough 302 itself is supported by a spring seat 308. The vibrator 306 includes an eccentric rotor, and its rotation causes the trough 302 to vibrate, causing the wire mesh 312 to function as a vibrating conveyor for advancing the substrate.

Activated carbon debris generated by friction 862 and activated carbon with weak force are reliably removed by the sieve 64.

Therefore, the activated carbon is prevented from accidentally falling off during subsequent packaging or use.

Second, although the present invention has been described in detail with reference to the preferred embodiments shown in the drawings, those skilled in the art to which the present invention pertains will understand that
Various modifications may be made to the core embodiment described above within the spirit of the invention.

[Effects of the Invention] According to the cleaning device 4 of the present invention, the activated carbon protruding above and below the base is scraped off by friction, and at this time, the vibration (-1"i) generated on the base causes the activated carbon that is weakly attached to the base to be scraped off. is peeled off from the substrate.By turning the driven roller toward the substrate (one force), the contact between the file belt and the substrate is good.Providing an operating lever makes it easy to replace the file belt.Furthermore, vibration By providing a type sieve, it becomes possible to more reliably remove the l-occupied charcoal debris and weakly adhesive activated carbon generated by the friction of the spear heald.
