Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a heating or cooling chamber that has a heat exchange air supply / exhaust mechanism and can efficiently exchange internal and external air while avoiding temperature changes in the chamber. It is a thing.

[Background of the Invention] Generally, when the gas in the chamber which is heated or cooled is exchanged with the gas outside the chamber, the temperature change in the chamber cannot be avoided simply by introducing the outside air and exhausting the inside air. A heat exchange means for that purpose is known, but the structure is complicated and cannot be easily provided.

That is, since the structure has been complicated and inefficient in the past, the temperature drops in the heating state and rises in the cooling state so that the temperature condition in the chamber cannot be constantly maintained at a constant level. However, there is a problem in that the heating or cooling means must be operated more than necessary.

Regarding this problem, the present inventor has previously mentioned that
As No. 4009, we developed and proposed an inside / outside air intake / exhaust device for a reduced pressure equilibrium frictional heat generation mechanism. The inside air / outside air suction / exhaust device is configured to forcibly suck the air in the sealed chamber by the rotating action of the rotating pair to exhaust the air to the outside through the inside air discharge unit, reduce the pressure in the chamber and reduce the pressure difference between the inside and outside of the chamber. While maintaining a substantially constant equilibrium state, while maintaining this equilibrium state, the rotating action of the rotating body is continued to promote the friction action with air to generate friction heat, and the friction heat heats the chamber. In the decompression equilibrium frictional heat generation mechanism for decompressing and heating the processed material in the chamber, the outside air suction part is integrally incorporated into the inside air discharge part exhausted by the rotating action of the rotating body, and the heat exchange mechanism. Is formed.

Moreover, the reduced pressure equilibrium friction heat generation mechanism shown as a heat source is
Further, the present inventor has proposed the basic technique and its applied technique shown in Japanese Patent Publication No. 60-22263, Japanese Patent Publication No. 60-22264, Japanese Patent Publication No. 59-52753, and Japanese Patent Publication No. 59-52342. .

[Outline of the Invention] However, in the present invention, not only the above-mentioned decompression equilibrium frictional heat generation mechanism is used as a heat source, but other generally known power source heaters and all heat sources using fuel are decompressed. In addition, the structure is not only intended to be widely used for a chamber held in a pressurized state, but also used in a chamber having a heat source for cooling held in a depressurized or pressurized cooled state. Its basic purpose is to be simple and versatile.

That is, the present invention uses the pressure fluctuation of the gas in the chamber, which has a pressure change such as pressurization or decompression compared to the outside air, and which always has a desired temperature difference from the outside air. An object of the present invention is to provide a heating or cooling chamber in which heat loss can be effectively exchanged with the inside air in the chamber.

The casing with the heat exchange part can be easily attached to any type of chamber by its attachment part by simply perforating the chamber so that the ends of the inside air discharge part and the outside air intake part can communicate with the inside of the chamber. Since it is the outside air intake part and the inside air discharge part, the heat exchange efficiency is also high.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 2 and FIG. 2 are views showing the basic configuration of this invention. In this embodiment, a desired heat source G and a depressurizing or pressurizing means (not shown) are provided in the chamber 1 for storing the processed material, and generate the inside air having a desired temperature difference and pressure difference as compared with the outside air. It can be done.

An opening / closing door 2 is pivotally supported in the chamber 1 so that the processed material can be put in and out.

In the drawing, 3 is a tubular casing that constitutes the heat exchange air supply / exhaust mechanism A, 4 is a tubular outside air intake portion wound inside the casing 1, and 5 is tubular inside air discharge that is also wound inside the casing 3. Each of the parts is shown, and a heat exchange part T is formed so as to be able to exchange heat with each other and incorporated in the casing 3. Then, one end of the both parts 4, 5 faces one end of the casing 3, and the other end of the both parts 4, 5 faces the other end of the casing 3, respectively. One end portions 4a and 5a of 5 are inserted into the chamber 1, and the other end portions 4b and 5b of both portions 4 and 5 are configured to communicate with the outside air to be released. Further, one end 4a or 5a of either one of the both parts 4 and 5 is connected to the pressure difference generating means. For example, when a pressure reducing means is provided in the chamber 1 as a pressure difference generating means, one end portion 5a of the inside air discharging portion 5 is connected to the exhaust portion of the pressure reducing means, and the pressurizing means is provided in the chamber. When provided, the other end portion 4a of the outside air suction portion 4 is connected to the suction portion of the pressurizing means. Reference numerals 6, 76 and 7 denote open / close valves for the outside air intake portion 4 and the inside air discharge portion 5, and may be used for only one of them. Reference numeral 8 denotes a brim-shaped mounting portion provided on the casing 3, and the heat exchange air supply / exhaust mechanism A can be airtightly fixed to the side surface of the chamber 1 by using a mounting tool 8a such as a mounting screw. At this time, the end portions 4a, 5a of the outside air intake portion 4 and the inside air discharge portion 5 of the casing 3 are inserted into the mounting hole 10 of the chamber 1 so as to face the inside of the chamber 1.

The operation will be described based on the above configuration.

The heat exchange air supply / exhaust mechanism A is air-tightly fixed to the chamber 1 by the attachment 8a using the attachment portion 8 of the caging 3.

Then, a desired high temperature or low temperature inside air is obtained in the chamber 1 by the heat source G, and the outside air and the desired pressure are obtained by a desired depressurizing or pressurizing means (not shown) such as a rotating body or a pump or other appropriate means. A gas holding the difference is obtained.

When it is desired to exchange the inside air with the outside air in such a state, for example, to remove the vapor and the odor in the chamber 1, the opening / closing valves 6 and 7 can be opened to open the casing 3.
The inside air intake portion 4 and the inside air discharge portion 5 inside communicate with the inside and outside of the chamber 1, respectively, and gas is moved in opposite directions. That is, when the pressure difference generating means provided in the chamber is the pressure reducing means, the inside air is discharged through the inside air discharging portion 5 connected to the exhaust portion,
The same amount of outside air is sucked in from the outside air suction portion 4, and the inside and outside air is replaced. Further, when the pressurizing means is provided in the chamber, the outside air is introduced into the chamber 1 from the outside air intake portion 4 connected to the intake portion, and the same amount of the inside air is discharged from the inside air discharge portion 5. Then the inside and outside air is replaced.

This exchange of the inside air and the outside air is surely performed without heat loss because the two outside air suction portions 4 and the inside air discharge portion 5 forming the heat exchange section are tubular and form a winding structure. Therefore, theoretically, the inside air and the outside air can be exchanged without causing a temperature change.

Therefore, the atmospheric fluid in the chamber 1, that is, the inside air, that is, the object to be dried, the object to be heated, the object to be heated, the object to be cooled, and the like, which is contained in the chamber 1, can be exchanged with the outside air very effectively.

In the above-mentioned embodiment, the shape and structure of the outside air intake portion 4 and the inside air discharge portion 5 may be any desired one, and the shape of the casing 3 is not specified in any way. Of course, the auxiliary structure of can be provided.

Further, as a method of fixing to the chamber 1 by further using the mounting portion 8 of the casing 3, not only adhesion using an adhesive but also welding, welding or the like can be freely performed.

Next, another embodiment of the present invention will be described with reference to FIGS. Incidentally, the caging 3X, its mounting portion 8X, and the means for mounting it on the chamber are exactly the same as in the above-mentioned embodiment, so a detailed description thereof will be omitted.

Reference numeral 9 denotes an inside air discharge portion having a tubular structure, and one end of this inside air discharge portion 9 has an exhaust side opening portion of a reduced pressure friction heat generation mechanism (decompression generation means) G as a heat source and a pressure difference generation means described later. (Exhaust part) Ga is connected through a casing 3X, and the other end is arranged outside the chamber 1 and communicates with the outside air. Furthermore, the inside air discharge part 9 is configured with a passage 12 formed by a large number of parallel heat exchange plates 10a and an outer side of a large number of heat exchange tubes 11 that intersect the heat exchange plates 10a at right angles, It is desirable to keep the required length from the inside of the chamber 1 to the outside.

Reference numeral 13 denotes an outside air intake portion integrally incorporated with the inside air discharge portion 9 in the casing 3X. The outside air intake portion 9 is covered with a pipe body 14, and a plurality of heat exchange tubes 11 have openings 11 at both end portions.
a) and 11a, two rows of spaces 14, 14 are formed, and a large number of partition walls 15 are provided in the spaces 14, 14 so as to be offset from each other. The heat exchange tube 11 and the meandering passage 18 communicating with the partition wall 15 toward the opening 17 at the base end facing the heat exchange section T constitute the heat exchange section T as a whole.

The opening / closing valve 16 of the outside air suction unit 13 can be opened / closed not only by being manually operated but also by being controlled in association with the temperature inside the chamber 1 or by being controlled by a timer.

By the way, the reduced pressure frictional heat generating mechanism that constitutes the heat source G is configured by the electric motor 19, one or more fans 20, and a tubular cylinder 21 that covers the fan 20, and between the fan 20 and the tubular cylinder 21. A minute gap g is formed in the space, and a frictional heat generation part 22 is formed in the space formed by the tubular cylinder 21 in which the fan 20 rotates, so that the effect of friction with stagnant air can be improved. The reduced pressure frictional heat generation mechanism G can freely change the diameter of the fan 20, the number of the blades 20a, the inclination angle of the blades 20a, the distance between the fans 20, the number of the attached fans 20, and the like. The configuration shown in "Rotating body with multi-stage fan" of No. 57-55089 can be adopted. The fan 20 is composed of rotating blades 20 a such as a propeller fan and a sirocco fan, has a desired inclination angle, and has a rotation direction determined so as to suck the air in the chamber 1.

In addition, 23 is an intake side opening Gb of the reduced pressure frictional heat generation mechanism G.
, 24 is a recirculation cylinder, and 25 is a partition wall having a concave cross section that blocks the reduced pressure frictional heat generation mechanism G.
The opening 26 and the opening 17 of the outside air introducing portion 13 are opened and a small opening 27 for circulating the inside air is formed. Reference numeral 28 denotes an outside air introducing small tube for preventing heating of the electric motor 19. Reference numeral 29 is a pipe provided in the chamber 1 so that it can be opened to the outside air and can be connected to another pump or the like. 30 is a valve.

Next, the operation will be described based on the above configuration.

If the electric motor 19 is energized and the fan 20 is rotated,
The depressurized frictional heat generation mechanism G operates, and the air in the chamber 1 that is hermetically sealed is first sucked and exhausted by the fan 20.
The air is gradually exhausted through the inside air exhaust unit 9, the pressure inside the chamber 1 is reduced, and the pressure difference between the inside and outside of the chamber 1 gradually increases. Then, when a certain pressure difference is reached, a substantially constant equilibrium state is maintained. In this equilibrium state, an air retention phenomenon occurs in the frictional heat generation part 22 in the rotation region of the fan 20, and the frictional action with the fan 20 continues again, so that the frictional heat propagates into the chamber 1 and prefers the room. Can be heated to the temperature of.

Therefore, if the object to be processed is housed in the chamber 1,
The release of water contained in the object to be treated is enhanced by the depressurization action, and the heating action due to the rise in room temperature promotes the generation of a free liquid of the object to be subjected to operations such as highly efficient drying and water extraction. You can

When the on-off valve 16 is opened in association with the timer or the temperature in the chamber 1, the outside air passes through the passage 18 from the on-off valve 16 of the outside air suction portion 13, and the multiple heat exchange tubes 11 and the two rows. The water-containing gas in the chamber 1 corresponding to the inflow capacity diffuses and flows into the chamber 1 while meandering through the spaces 14 and 14, and flows out from the passage 12 of the discharge part 9 of the reduced pressure parallel friction heat generation mechanism G. Is discharged.

By the way, since the passage 12 of the inside air discharge portion is formed by a large number of heat exchange plates 10a constituting the heat exchange portion T and a large number of heat exchange tubes 11, the outside air suction portion 13 flowing through the heat exchange tubes 11 is formed. Heat is effectively exchanged with the outside air flowing in, and the moisture in the water-containing gas is radiatively cooled and can be completely removed as condensed water.

The circulating air in the chamber 1 is
Effectively performed by the reflux cylinder 24 and the small mouth 26,
For example, heating and drying of the object to be treated can be accelerated.
