Description

  The present invention relates to a soundproof box for a water removal or dust removal apparatus that blows off water droplets, dust, and the like attached to the surface of an object to be processed by compressed air.

2. Description of the Related Art Conventionally, there has been known an apparatus that blows off water droplets and dust on the surface of an object to be processed with a jet force of compressed air.
An example of this type of apparatus is a water removal apparatus shown in FIG.
In this dewatering apparatus, a net conveyor 2 is provided on the upper part of the apparatus main body 1, and a processing object is placed on the transport surface 2a of the net conveyor for transport.
A unit cover 3 that can cover or release the transport surface 2 a of the net conveyor 2 is provided on the upper surface of the apparatus body 1, and an air injection unit 4 is mounted in the unit cover 3. The air injection unit 4 is provided with a plurality of air injection nozzles (not shown). The air injection nozzles inject compressed air guided from a compressed air source (not shown), and the injection port rotates by the injection reaction force. .

An air injection unit 5 is provided below the net conveyor 2, and the air injection unit 5 is also provided with a plurality of air injection nozzles (not shown).
If this apparatus is operated with the unit cover 3 closed, the compressed air is jetted from the air jet nozzles of the upper and lower air jet units 4 and 5 toward the processing object on the transport surface 2a. Water droplets adhering to the surface of an object can be blown away.

Furthermore, a soundproof box 6 is attached to the apparatus main body 1 of the water removal apparatus so as to be openable and closable so that the unit cover 3 can be covered and released.
Such a soundproof box 6 is provided for the following reason.
During operation of the water removal apparatus, compressed air is injected from a number of air injection nozzles. For this reason, the injection sound of compressed air, the turbulent sound after injection, the collision sound of air against the object to be processed, the vibration sound of the object to be processed on the transport surface 2a, etc. are generated, which becomes a noise source. is there. This noise is very uncomfortable for workers who have to work around the water removal device, and sometimes causes health problems. Therefore, surrounding noise is reduced by covering the unit cover 3 with the soundproof box 6.

The noise box 6 is made of, for example, a metal such as stainless steel, and has a size that covers the unit cover 3 and a sponge-like sound absorbing plate (not shown) on the inner surface of the box body 7 that has a doorway for processing objects. Adhered with. This sound absorbing plate absorbs noise generated in the unit cover 3.
The compressed air ejected from the air ejecting units 4 and 5 can blow off dust and the like attached to the surface of an object conveyed by the net conveyor 2. That is, the same configuration as the water removal device shown in FIG. 8 can be used as a dust removal device. Even in such a dust removing device, noise similar to that in the water removing device is generated, and therefore the noise is reduced by providing the soundproof box 6.

JP-A-2005-345018 Japanese Utility Model Publication No. 55-142792

Since the box body 7 covers the unit cover 3 of the dewatering device, the water droplets blown off by the compressed air and ejected from the entrance / exit of the object to be treated of the unit cover 3 or the water vapor discharged from the exhaust port 8 It may stick to the inside of the main body 7. In the dust removing device, dust blown off with compressed air may adhere to the inside of the box body 7.
Water droplets and dust adhering to the inside of the box body 7 must be removed by cleaning, but it is troublesome to sufficiently remove water droplets and dust adhering to the sponge-like sound absorbing plate.
Moreover, since the sound absorbing plate is bonded to the box body 7 with an adhesive, it is difficult to clean the sound absorbing plate.

Furthermore, if the amount of water absorption to the sound absorbing plate is increased, the sound absorbing effect is reduced. Further, if the sound absorbing plate is left to absorb moisture, it may cause mold and the hygienic environment cannot be maintained.
However, it takes time to dry the sound absorbing plate bonded to the box body 7 with an adhesive.
Also in the dust removing device, dust adheres to the box body 7 of the soundproof box, and if it is left unattended, the accumulated dust may fall onto the transport surface 2a. In this case, the foreign matter reattaches to the processing target that has been removed with great effort.
Therefore, especially when the water removal or dust removal device is incorporated in the food production line, it is necessary to clean the inside of the box body 7 and keep it always clean.

However, as described above, a sponge-like sound absorbing plate is adhered to the inside of the box body 7, and it takes time and effort to remove water droplets and dust adhering to the sound absorbing plate.
Since the box main body 7 is attached to the main body of the water removing device or the dust removing device, when the inside of the box main body 7 is opened and the inside is cleaned, dust or the like may be dropped on the transport surface 2a. If dust or the like is dropped onto the transport surface 2a, foreign matter will be reattached to the treated object that has been removed with great care, so that sufficient care must be taken in cleaning the box body 7. As described above, cleaning that requires careful attention has a problem that workability is further deteriorated.

As a result, due to the cleaning work in the soundproof box, it takes a long time to stop the water removal and dust removal process, and there is a problem that the production efficiency in the production line including these processes decreases.
Moreover, even if it is going to replace the dirty sound absorbing plate, the sound absorbing plate bonded with the adhesive must be forcibly peeled off from the box body 7, and if the adhesive remains, a new sound absorbing plate should be pasted cleanly. There were times when I couldn't.

  An object of the present invention is to provide a soundproof box for a water removal or dust removal device that can easily clean and replace a sound absorbing plate.

According to a first aspect of the present invention, there is provided an air injection for injecting compressed air toward a processing object conveyed by the conveying means in a unit cover that can be opened and closed with respect to a conveying surface of the conveying means provided in the apparatus main body. Assumes a soundproof box used for water removal or dust removal equipment with a built-in unit.
A box main body that covers and releases the unit cover is attached to the apparatus main body so as to be openable and closable, and four inner side surfaces that stand in a closed state of the box main body are provided along a lower end opening edge. A channel-shaped weight support portion and a channel-shaped collapse prevention support portion extending in a direction parallel or orthogonal to the weight support portion, and provided in the channel between the weight support portion and the fall prevention support portion. In addition, a sponge-like side sound absorbing plate that covers each inner side surface is fitted, and the ceiling surface of the box body is provided with a channel-like ceiling support portion that follows the outline of the ceiling surface. An outer peripheral end of a sponge-like sound absorbing plate for ceiling covering the ceiling surface is fitted inside.

  According to a second aspect of the present invention, in the state in which the sound absorbing plate for side faces is in a state in which the box body is closed, a dimension in the height direction is maintained between the upper end of the sound absorbing plate and the ceiling surface. Provided, and the spacing constitutes the ceiling support.

  According to a third aspect of the present invention, any one of the side-surface sound-absorbing plate and the ceiling-type sound-absorbing plate is constituted by a plurality of divided sound-absorbing plates. A channel-like support part into which the outer periphery of the plate is fitted is provided.

According to this invention, the side surface and the ceiling surface are covered with the sponge-like sound absorbing plate, and the soundproofing effect is exhibited.
In addition, since the sponge-like sound absorbing plate can be easily attached to and detached from the channel while being bent, the sound absorbing plate separate from the box body can be cleaned, washed, and dried.

Therefore, the workability of cleaning the inside of the box body is improved, and the water removal device and the dust removal device are stopped for a long time for cleaning and drying in the box body, and the production efficiency is not lowered.
It is also possible to easily replace a dirty sound absorbing plate with a new sound absorbing plate.
Therefore, it becomes easy to keep the inside of the box body clean.
Furthermore, the sound absorbing plate can be kept in a dry state to prevent a decrease in the sound absorbing effect due to water absorption.

Further, the outer periphery of the sound absorbing plate is supported by a channel-shaped support portion, but the weight of the side sound absorbing plate is surely supported by the weight support portion, and the standing side sound absorbing plate is inclined by the fall prevention support portion. Can be prevented. In particular, even if the weight balance of the sound absorbing plate is lost due to water absorption, it can be reliably supported, so that the side sound absorbing plate does not vibrate and the sound absorbing effect is not reduced.
Furthermore, when attaching the sound absorbing plate, it is only necessary to insert the outer periphery into the channel while bending the sound absorbing plate, and the attaching operation is also simple.
In this way, reliable support can be realized while making it easy to attach and detach the sound absorbing plate.

  According to the second invention, the space between the upper end of the side-surface sound absorbing plate and the ceiling surface functions as a channel-like ceiling support portion, and the sound-absorbing plate is supported by inserting the sound-absorbing plate for ceiling into this space. Can do. Therefore, the entire ceiling surface can be covered with the ceiling sound absorbing plate without using a separate channel-shaped member to form the ceiling support section. In addition, the number of parts can be reduced because no separate member is required for the ceiling support.

According to the third aspect of the present invention, the individual size can be reduced by using the sound absorbing plate that covers each surface of the box body as a divided sound absorbing plate. Smaller sound absorbing plates are easier to handle, and workability of attaching / detaching work to / from the box body is improved.
Further, the outer periphery of the sound absorbing plate is supported by the support portion. However, if the outer periphery of the divided sound absorbing plate having a small area is supported, the sound absorbing plate can be supported more reliably than the sound absorbing plate having a large area.

The pair of channel members faces the channel members 31 and 32 (see FIG. 3) fixed to the side surface 10, and the side-surface sound absorbing plates are disposed between the side surfaces 11 and 13 similarly to the channel members 31 and 32. 29 and 30 are fixed to the side surface 12 while maintaining an interval corresponding to the thickness.
Then, as shown in FIG. 7, a rectangular side-surface sound absorbing plate 38 is fitted and supported in the channel of the support portion 21, the channel member 37, and the pair of channel members (not shown), and covers the side surface 12. Yes.

Next, the side surface 11 will be described. The side surface 11 is provided with channel-shaped support portions 16, 17, 18, 19, and 20 formed by bending the plate members that constitute the side surface 11 as described above.
Further, as shown in FIGS. 3 and 7, a channel member 39 is fixed above the side surface 11 with an interval corresponding to the thickness of the ceiling sound absorbing plate 27 c and the opening facing the opening of the support portion 16. Yes. The channel member 39 is provided with a length that covers substantially the entire length of the side surface 11 in the width direction.

On the side surface 11, the gate-shaped side sound absorbing plate 29 surrounded by the support parts 16, 17, 18, 19, the channel member 39, and the side surfaces 10, 12 is fitted into the channel at the outer periphery. It is supported.
The support portions 16, 17, and 18 that support the lower end of the side sound absorbing plate 29 are weight support portions of the present invention along the lower end opening edge of the box body 9, and support portions 19 and 20 extending vertically. The upper channel member 39 constitutes a fall prevention support portion.

  In this embodiment, the channel member 31 fixed to the side surface 10 in order to support one end surface in the width direction of the side surface sound absorbing plate 36 covering the side surface 10, and the width of the side surface sound absorbing plate 38 covering the side surface 12. In order to support one end face in the direction, the side-surface sound absorbing plate 29 is fitted in a space between the side surface 11 and a channel member (not shown) fixed to the side surface 12 (see FIG. 3). Therefore, the distance between the channel member that supports the side sound absorbing plates 36 and 38 and the side surface 11 functions as a channel-shaped collapse prevention support portion that supports the side sound absorbing plate 29.

Further, since the side surface 13 facing the side surface 11 is symmetrical with the side surface 11, the side sound absorbing plate 30 that covers the side surface 13 is supported by a member similar to the member provided on the side surface 11.
Specifically, the opening is made to face the opening of the support portion 22 at a position facing the channel member 39 on the side surface 11, that is, at a position corresponding to the thickness of the sound absorbing plate 27 a for the ceiling. The channel member 40 (see FIGS. 3 and 7) extending in parallel with the support portion 22 is fixed. The channel member 40 has a length that extends over substantially the entire length of the side surface 13 in the width direction.

The channel-shaped side acoustic plate 30 is supported by the channel member 40, the support portions 22, 23, 24 serving as weight support portions on the lower end side, and the support portions 25, 26 serving as fall prevention support portions. .
Also on the side surface 13 side, the distance between the side surface 13 and the channel member 32 for supporting the end surfaces in the width direction of the side sound absorbing plates 36 and 38 and the channel member (not shown) fixed to the side surface 13 is the side surface. It functions as a channel-shaped collapse prevention support portion that supports the sound absorbing plate 30.

As described above, the sound absorbing plates for side surfaces 29, 30, 36, and 38 that cover the four side surfaces of the box body 9 of this embodiment are all supported by fitting the outer periphery thereof into the channel of the support portion.
Accordingly, the outer side of the sound absorbing plates 29, 30, 36, and 38 can be taken out of the channel by being bent as a whole, and can also be fitted into the channel.

Next, support for the ceiling sound absorbing plates 27a, 27b, and 27c covering the ceiling surface 14 will be described.
In this embodiment, the ceiling surface 14 is covered with the ceiling sound absorbing plates 27a, 27b, and 27c having an area obtained by dividing the ceiling surface 14 into three equal parts. Each of the ceiling sound absorbing plates 27a, 27b, and 27c is a divided sound absorbing plate of the present invention.
Further, as described above, the channel members 28, 37, 39 are provided on the side surfaces 10, 11, 12, 13 with the ceiling surface 14 at intervals corresponding to the thickness of the ceiling sound absorbing plates 27 a, 27 b, 27 c. , 40 are fixed. Thus, the channel members 28, 37, 39, 40 fixed to the four side surfaces are provided along the outline of the ceiling surface 14, and these four channel members 28, 37, 39, 40 constitute a rectangular frame. ing.

The sound absorbing plates 27a, 27b, 27c for ceiling can be fitted between the channel members 28, 37, 39, 40 and the ceiling surface 14 to function as channel-shaped ceiling support portions. In short, the channel members 28, 37, 39, 40 and the ceiling surface 14 are combined to form a channel-like ceiling support portion, and the sound absorbing plates 27a, 27b, 27c for the ceiling are configured by the channel members 28, 37, 39, 40. It can be pushed between the frame and the ceiling surface 14.
Thus, if the sound absorbing plates 27a, 27b, 27c for ceiling are pushed between the frame and the ceiling surface 14, the edges of the sound absorbing plates 27a, 27b, 27c for ceiling are brought into close contact with the side surfaces 10, 11, 12, 13 Can be made.

In this embodiment, the side surface sound absorbing plates 29, 30, 36, and 38 that cover the side surfaces 10, 11, 12, and 13 are spaced between the upper end and the ceiling surface 14 by a distance corresponding to the thickness of the ceiling sound absorbing plate. It is a sound absorption board for the side provided with the dimension of the height direction in which is held.
Therefore, in this embodiment, the channel members 28, 37, 39, and 40 serve both as the function of the fall-preventing support portion of the side-surface sound absorbing plate and the function of the ceiling support portion, respectively.

In this embodiment, since the divided sound absorbing plate is used as the sound absorbing plate for the ceiling, the rod-like support members 41 and 42 are fixed to the ceiling surface 14 as support portions for supporting the outer periphery of each divided sound absorbing plate. is doing. These support members 41 and 42 are metal members in which channels are formed on both sides when fixed to the ceiling surface 14 as shown in FIG.
Then, a ceiling sound absorbing plate 27 a is bridged between the support member 41 and the channel member 40, and the ceiling sound absorbing plate 27 b is interposed between the support member 41 and the support member 42 and the channel member 39. The sound absorbing plate for ceiling 27c is bridged.

As described above, the sound absorbing plates 27, 27b, 27c for the ceiling are also supported by being fitted into the channel-like support portion, and thus can be easily detached from or fitted to the channel of the support portion.
The ceiling sound absorbing plate 27b located in the center of the three ceiling sound absorbing plates 27a, 27b, 27c is formed with openings corresponding to the exhaust windows 14a, 14b formed on the ceiling surface 14, and the exhaust window The steam and the like in the box body 9 are discharged by the fans attached to 14a and 14b.

As described above, in the soundproof box of this embodiment, the sound absorbing plate for side surface and the sound absorbing plate for ceiling covering the inside of the box body 9 can be easily attached to and detached from the channel of the support portion. Therefore, when cleaning the inside of the box body 9, the sound absorbing plate can be removed, and the box body 9 and the sound absorbing plate can be cleaned separately. Since the sound absorbing plate can be removed from the box body, it is easy to clean the sound absorbing material, dry it, or replace it with a new sound absorbing plate.
Therefore, the inside of the box body 9 can be kept clean without taking time for cleaning and replacement.

  In this embodiment, the side-surface sound absorbing plate is reliably supported by the weight support portion and the fall prevention support portion. For this reason, it is possible to prevent the sound absorbing plate from shifting when the water removing or dust removing device is used while making the side sound absorbing plate detachable. In particular, when used in a water removal device, there is a possibility that the sound absorbing plate absorbs water and the weight increases or the weight balance is lost. By providing the fall prevention support portion, it is possible to prevent the side sound absorbing plate from falling down or shifting.

The box body 9 is constructed by providing the support portions on the plate members constituting the surfaces 10, 11, 12, 13, and 14 and then combining them in a box shape and welding the joint portions.
And each said support part does not need to support the perimeter of a sound-absorbing board. The support part should just be provided with the length which can be supported in the range in which each sound-absorbing board does not slip | deviate or fall down, and may be comprised with the some member divided | segmented into the longitudinal direction.

In this embodiment, the ceiling sound-absorbing plate is constituted by three divided sound-absorbing plates, but the number of divisions of the ceiling sound-absorbing plate may be any number and may be constituted by one member.
Further, the side sound absorbing plate may be constituted by a plurality of divided sound absorbing plates.
When the sound absorbing plate for ceiling or the sound absorbing plate for wall surface is composed of a plurality of divided sound absorbing plates, the weight of each member is smaller compared to the case where it is composed of one member. There is an advantage that it becomes easy. On the other hand, the number of members to be attached and detached increases, which may take time. Therefore, the number of divided sound absorbing plates is preferably determined according to the area of the side surface or ceiling surface, the weight of the sound absorbing plate, and the like.

Further, the weight support portion that supports the lower end of the sound absorbing plate may be formed by attaching a channel member different from the side surface, instead of bending the plate member forming the side surface as described above.
Further, the weight support portion may be continuously formed with drain holes in the longitudinal direction so that the moisture absorbed by the sound absorbing plate is discharged to the outside.
In addition, although the said embodiment demonstrated the soundproof box attached to a water removal apparatus, the said box main body 9 can be used as a soundproof box for dust removal apparatuses, and the effect similar to the above is acquired also in that case.

Further, a sound-damping plate may be interposed between the sound-absorbing plate and each surface to further enhance the soundproofing effect.
The damping plate can be fixed to the side surfaces 10, 11, 12, 13 and the ceiling surface 14 with an adhesive or the like, avoiding the support portions. Since this damping plate is covered with a sound absorbing plate, water droplets and dust do not directly adhere to it, and since it is not a sponge like the sound absorbing plate, moisture does not permeate. By the way, if the sound absorbing plate is removed, the surface of the damping plate can be easily wiped off if moisture or dust adheres to it.

  Ideal for water removal or dust removal equipment used in strict hygiene processes such as food processing.
