Description

TECHNICAL FIELD The present invention relates to a high-temperature processing apparatus that constitutes, for example, a beverage brewing apparatus at the factory level, and more particularly to a heat insulation structure that insulates the outside.

For example, in food and beverage plants, a high-temperature treatment apparatus mainly composed of a container that is in a high temperature state is widely used for heat treatment of materials (materials to be treated) (see, for example, Patent Document 1). .
In order to ensure a safe working environment for these devices, heat insulating materials are attached to the surfaces of the devices that become hot, so that workers can concentrate on management operations even near the devices without worrying about these high-temperature parts. I have to. By the way, covering with such a heat insulating material enhances the heat insulation state inside the device and suppresses the consumption of thermal energy.

However, in the current high-temperature processing equipment, considering the pressure in the container body and the strength at the time of installation, the container body is formed with sufficient mechanical strength, and furthermore, the container body is formed with support members and auxiliary equipment. As a result, sufficient heat insulating or heat shielding structure is not adopted in those parts.
Specifically, as shown in FIG. 5, for example, the container body 2' is made of a thick steel plate exhibiting sufficient mechanical strength, and the support members 4' are projected from several places on the side surface of the container body 2'. , and the installation contact surface 4S' is placed on the installation surface S, and the entire device is partially embedded in the installation surface S and suspended from the installation surface S. - 特許庁The heat insulating material D is attached to the portion above the installation surface S of the container body 2' to ensure the safety of the work.

However, in such a configuration, since the support member 4' is directly fixed to the container body 2' which becomes hot, the heat of the container body 2' is directly transmitted to the support member 4', for example, the support member 4' is exposed. Depending on the form of the apparatus, the support member 4' reaches a temperature of about 140° C., which is the same as the inside of the container body 2', and the operator M must pay sufficient attention to the support member 4' located at his/her feet during the work. was there. For this reason, as shown in FIG. 5, measures such as covering the periphery of the supporting leg member 4' projecting to the outer peripheral side of the container body 2' with a heat insulating material D or a cover may be taken at the site. Such a heat insulating material D and a cover lead to a narrow space for placing the feet of the worker M, and the worker M needs to pay more attention to his/her feet.

Japanese Patent Application Laid-Open No. 2001-300205

The present invention has been made in recognition of such a background, and has as its technical object the development of a novel thermal insulation structure in a high-temperature processing apparatus capable of achieving sufficient heat insulation or thermal insulation. .

First, the thermal insulation structure in the high-temperature processing apparatus according to claim 1 is

The container body is covered with an outer frame while maintaining an insulating gap on the outer peripheral surface thereof,
The high-temperature processing apparatus is provided with a supporting leg member for installing the device on an installation surface, and the supporting leg member is provided so as to protrude from the outer frame, not the container body, to the outer peripheral side ,
Further, the high-temperature processing apparatus is installed in an embedded and suspended state such that the bottom of the container body penetrates the installation surface, and the support member has a contact surface with respect to the installation surface that is high in the high-temperature processing apparatus. The outer frame is provided at an intermediate position in the vertical direction, and the lower end of the outer frame is formed to a range below the installation surface slab .

In addition to the requirements of claim 1 , the heat insulating structure in the high-temperature processing apparatus according to claim 2 ,
The container body has an opening/closing lid at the bottom, and the high-temperature processing apparatus has a bracket for supporting a shift device of the opening/closing lid, and the bracket is fixedly supported not on the container body but on the outer frame. It is characterized by being a configuration.

In addition to the requirements of claim 1 or 2 , the heat insulating structure in the high-temperature processing apparatus according to claim 3 has the following features:
The container body is provided with an external extension member that penetrates the outer frame and communicates the inside of the container body with the outside. It is characterized by a configuration in which an opening is formed and a mouth ring is provided which tightly surrounds the outer extension member.

The above problems are solved by means of the configuration of the invention described in each of these claims.
First, according to the first aspect of the invention, the outer frame is provided with a heat insulating gap so as to cover the container body that becomes hot, and the support member is provided for the outer frame. The heat of the container body is not directly transmitted to the . Therefore, it is possible to avoid deterioration of the working environment due to the high temperature of the supporting leg member as in the conventional art. By the way, with this configuration, even if the inside of the container main body reaches, for example, about 140° C., the temperature of the support member can be suppressed to about 40° C., which is almost the same as or slightly higher than the room temperature. confirmed by humans.
In addition, according to the present invention, since the high-temperature processing apparatus is installed in a semi-embedded manner with respect to the installation surface, it is possible to operate the apparatus at a location near the operator's hand, which is excellent in operability. A device is obtained. In addition, since the outer frame that has a heat shielding effect (heat shielding effect) has a structure that fully covers the container body from the installation surface to below, the part located on the installation surface does not become hot.

Further, according to the second aspect of the invention, the opening and closing door is provided at the bottom of the container body, and the bracket that supports the shift device is also attached to the outer frame instead of the container body. do not have.

According to the third aspect of the present invention, the container body is provided with an external extension member that penetrates the outer frame to allow the inside of the container body to communicate with the outside (the outside of the device). A distortion relief gap (receiving opening) is secured between the extension member and the outer frame, and a mouth ring is provided on the outer peripheral side of the outer extension member, so that effective heat insulation can be achieved at the position of the outer extension member. .

1 is a longitudinal side view showing a high-temperature processing apparatus according to the present invention; FIG. It is a top view same as the above. FIG. 4 is an enlarged cross-sectional view of an assembled portion of an outer frame and an outer extension member in the high-temperature processing apparatus; It is a vertical side view which shows a stand type high temperature processing apparatus. It is a vertical side view which shows the conventional high temperature processing apparatus.

The modes for carrying out the present invention include those described in the following examples, as well as various techniques that can be improved within the technical concept thereof.
In addition, in the explanation, while explaining the high-temperature processing apparatus 1 (hereinafter simply referred to as "high-temperature processing apparatus 1") to which the heat-insulating structure of the present invention is applied, the heat-insulating structure (heat-insulating structure in the high-temperature processing apparatus ) will be explained.

As shown in FIG. 1 as an example, a high-temperature processing apparatus 1 according to the present invention has a sealable container body 2 as a main member, in which a material to be processed is accommodated and hot water (hot water) is supplied to the inside of the container body. It is a device that performs appropriate processing in a high temperature state by means of, for example, hot water (high temperature water) supplied as one of the processing to extract the extract (umami component) contained in the material to be processed. are mentioned. In particular, coffee grounds, tea leaves, etc. are used as materials to be processed, and a beverage extraction process for extracting coffee, tea, etc. from these is assumed.

Of course, the high-temperature processing apparatus 1 can be applied to various processing apparatuses such as a retort heating apparatus in which the container body 2, which is a tank, is heated to a high temperature, in addition to such a beverage extractor.
Further, as the working medium for heating the material to be treated, either one or both of a liquid and a gas can be assumed. Here, high-temperature water (hot water), pressurized hot water, etc. can be applied as the liquid, and wet steam, dry steam, etc. can be applied as the gas.

In addition to the container body 2 described above, the components of the high-temperature treatment apparatus 1 include an outer frame 3 provided on the outer peripheral side of the container body 2 at a substantially constant interval, and the high-temperature treatment apparatus 1 (container body 2). on an installation surface (mounting surface) S (see FIG. 2). Here, the gap (space) formed between the container body 2 and the outer frame 3 is a gap that prevents the heat of the container body 2, which is in a high temperature state, from being transmitted to the outer frame 3. Let the gap be 3S.
Further, in the present invention, the support member 4 is arranged not on the container body 2, which is exposed to a high temperature, but on the outer frame 3, which is provided on the outside of the container body while maintaining the heat insulation gap 3S. It is provided, and this is one of the major features. That is, the supporting leg member 4 is fixed by welding or the like to the outer frame 3 on the outside of the container body 2 rather than to the container body 2 .

Further, the container body 2 has an open/close lid 21 at the bottom. Particularly, in this embodiment, the bottom of the container body 2 is formed as the open/close lid 21, and the entire bottom is formed to open and close. For this reason, the high-temperature processing apparatus 1 is provided with a bracket 5 for supporting the shift device 22 of the opening/closing lid 21. In this embodiment, the bracket 5 is also fixed to the outer frame 3 instead of the container body 2. Supported.

Further, in the high-temperature processing apparatus 1, as shown in FIGS. 1 and 3 as an example, an external extension member 6 that penetrates the outer frame 3 and communicates the inside of the container body 2 with the outside is provided, for example, at the top of the container body 2. It is provided in an inclined state. For this reason, the outer frame 3 is formed with a receiving opening 31 having a distortion relief gap larger than the external shape of the outer extension member 6 at this through portion. A mouth ring 32 is provided on the outer circumference of the external extension member 6 to closely surround it.
An opening/closing door 61 is also provided at the outer tip (protruding tip) of the external extension member 6. This opening/closing door 61 is smaller than the opening/closing lid 21, and is mainly used when the material to be treated is introduced into the container body. However, during maintenance, the worker M may enter the container main body from here (so-called manhole).

Next, a basic installation mode of such a high-temperature processing apparatus 1 will be described.
The high-temperature processing apparatus 1 is installed in such a way that the bottom of the container body 2 penetrates the installation surface S as shown in FIG. 1 as an example. Therefore, if the installation floor is the first floor, the bottom of the container body 2 protrudes into the underground space and is provided in a state as if it were suspended. For this reason, such a mounting state is sometimes referred to herein as a "recessed suspension state" or "recessed type." In addition, due to such an installation form, the installation contact surface 4S of the support member 4 (the installation contact surface 4S with respect to the installation surface S) is provided so as to be located at the middle position of the high-temperature processing apparatus 1 in the height direction.
In addition, the installation mode of such an embedded hanging state is adopted because the container main body 2 is often formed higher than the height of the worker M, and for example, the worker M pulls the material to be processed from the external extension member 6. This is for facilitating the work of charging the container and the work of monitoring the inside of the container body 2 from above.
Each member constituting the high-temperature processing apparatus 1 will be described in detail below.

First, the container body 2 will be described.
As described above, the container body 2 is a portion that receives the material to be processed, hot water, etc., and serves as a substantial processing space. As an example, as shown in FIG. It is formed as a cylindrical pressure vessel with a shape. Reference numerals 2B, 2U, and 2D in the drawing indicate a cylindrical body portion, a flat dome-shaped upper portion, and a flat dome-shaped lower portion, respectively, of the container body 2 .
The container body 2 is made of a stainless steel plate with a thickness of about 8 mm, for example, when the applied pressure (withstanding pressure) is 0.4 to 0.6 MPa, the internal volume is about 3.0 m ³ , and the temperature is 140 to 150°C. be done.
Further, in this embodiment, the lower portion 2D (bottom portion) of the container body 2 is formed as the opening/closing lid 21 that opens and closes downward as a whole as described above. The opening/closing lid 21 is opened when taking out the material to be treated (so-called material residue) after treatment, but it can also be opened when performing maintenance inside the container body.
Since the container main body 2 becomes a substantial processing space as described above, the temperature of the container main body itself also reaches a high temperature of about 140 to 150° C. during processing.

Next, the outer frame 3 will be explained.
The outer frame 3 is a shell-like member that covers the container body 2 while maintaining an appropriate heat insulating gap 3S from the outside of the container body 2, as described above. It is preferable to fill the heat insulating gap 3S with a heat insulating material (especially heat insulating material) such as rock wool having excellent heat insulating performance. can be obtained, it is not necessary to fill the heat insulating gap 3S with the above heat insulating material (special heat insulating material). In addition to the rock wool described above, examples of the heat insulating material (special heat insulating material) include glass wool, foam heat insulating material (perlite), and the like. Such an outer frame 3 makes it difficult for the heat of the container body 2, which has a high temperature, to be transmitted to the support member 4 and the bracket 5. As shown in FIG.

The outer frame 3 not only covers the part of the container body 2 protruding upward from the installation surface S, but also covers the container body 2 so as to wrap around the installation surface S to some extent. Therefore, the lower end of the outer frame 3 is configured to pass through the installation surface slab and reach the lower range (specifically, near the middle of the trunk portion 2B of the container body 2).
As described above, in this embodiment, the outer frame 3 wraps around the installation surface S to cover the container body 2 to a large extent. It is difficult to reach a high temperature (a high temperature comparable to that of the container main body 2).

Since the support members 4 and the brackets 5 are attached to the outer frame 3, the outer frame 3 is made of a stainless steel plate having a thickness of about 6 mm, for example, in order to maintain the strength of the frame.
Further, the high-temperature processing apparatus 1 is provided with the external extension member 6 so as to pass through the outer frame 3 as described above. For this reason, as shown in FIG. 3 as an example, the outer frame 3 is formed with a receiving opening 31 having a strain relief gap larger than the outer shape of the outer extension member 6 at the through portion.
Here, since the external extension member 6 is directly connected to the container body 2 , the external extension member 6 itself becomes hot and may be distorted. It is something that cannot be done.

Next, the support member 4 will be described.
As described above, the support member 4 is an installation member for installing the container body 2 (high-temperature processing apparatus 1) on the installation surface S (especially here, in an embedded and suspended state), as shown in FIG. Next, a horizontal plate 42 is joined to the lower part of the vertical plate 41 to form a T-shaped cross section (inverted T-shaped), and the lower flat surface of the horizontal plate 42 is used as the installation surface 4S. It is made to abut on S. In addition, when fixing the plate thus assembled to the outer frame 3 , it is further stretched (fixedly installed) on the side peripheral surface of the outer frame 3 through the arc-shaped mounting plate 43 by welding or the like.
Here, in the present invention, the supporting leg member 4 is fixedly installed in an overhanging manner from the outer frame 3, which is the outer shell, rather than the container body 2, which is exposed to high temperatures, so that it does not come into direct contact with the container body 2. Therefore, as described above, even if the temperature of the container body 2 becomes high, the temperature of the support member 4 does not reach the same level. Specifically, even when the temperature of the container body 2 is 140 to 150°C, the support member 4 can be kept at about 40°C. By the way, the conventional supporting leg member 4' reaches a high temperature of about 140 to 150° C., which is almost the same as that of the container body 2.

Next, the bracket 5 will be explained.
As described above, the bracket 5 supports the shift device 22 for opening and closing the opening/closing lid 21. The bracket 5, like the support member 4, is fixed and supported to the outer frame 3 by welding or the like.
Here, the opening/closing mechanism of the opening/closing lid 21 in the container body 2 will be described.
When opening and closing the open/close lid 21, as shown in FIG. 1, a bell-crank arm 24 is rotatably supported by a pivot-shaped hinge 23 as viewed from the side. The opening/closing lid 21 is fixed to (opposite side of the hinge 23), and a slider of a shift device 22 (for example, a hydraulic cylinder) is connected to the other end. The base of the shift device 22 is rotatably supported by the bracket 5, and the opening/closing lid 21 can be opened and closed by extending and contracting the slider of the shift device 22. there is

Next, details of the bracket 5 will be described.
As an example, as shown in FIG. 1, the bracket 5 is formed by joining vertical plates 52 to both ends of a horizontal plate 51 and joining these three plates so as to form an H-shaped cross section. A reinforcing plate 53 is provided on the upper portion of the horizontal plate 51, and the base portion of the shift device 22 is rotatably attached below the horizontal plate 51. As shown in FIG. A reinforcement plate 54 is also joined to the lower end of the vertical plate 52 inwardly. When the plate thus assembled is fixed to the outer frame 3, it is fixed and supported on the outer peripheral surface of the outer frame 3 by welding or the like through the arc-shaped mounting plate 55, similar to the support member 4. is.
The inward reinforcement plate 54 joined to the lower end of the vertical plate 52 is fixed to the installation surface S and constitutes the installation contact surface 4S. Therefore, the bracket 5 functions to support the shift device 22 and also functions as the supporting leg member 4 .
Incidentally, in this embodiment, as an example, as shown in FIG. As for the supporting leg members 4 , the container main body 2 is installed on the installation surface S with a total of three supporting leg members 4 .
Of course, as described above, even if the temperature of the container body 2 reaches a high temperature of about 140 to 150° C., the bracket 5 can be kept at about 40° C. as well as the support member 4 .

Next, the external extension member 6 will be explained.
As described above, the external extension member 6 is a member that penetrates the outer frame 3 and communicates the inside of the container body 2 with the outside. is put into the container body 2 .
At the portion where the outer extension member 6 penetrates the outer frame 3, as shown in FIG. 3 as an example, a receiving opening 31 having a distortion relief gap larger than the outer shape of the outer extension member 6 is formed in the outer frame 3. .
Also, a mouth ring 32 is provided to closely surround the external extension member 6 so as to cover the receiving opening 31 . A caulk 33 made of silicone or the like is provided between the mouth ring 32 and the external extension member 6 (gap) to improve the airtightness of the mouth ring 32 (the mouth ring 32 separates the external extension member 6 from the gap). I try to surround it densely). Of course, the mouth ring 32 can be densely provided between the mouth ring 32 and the external extension member 6 (gap) with a packing interposed therebetween, in which case the caulking 33 as described above is not necessary.

In addition to the above-described members, the container body 2 includes various pipes and devices for performing high-temperature processing or maintaining the device, such as pressure pipes, exhaust pipes, hot water supply pipes, cleaning pipes, pressure sensors, A monitoring window or the like is appropriately provided.

In the basic embodiment described above, the configuration in which the container body 2 (high-temperature processing apparatus 1) is installed in an embedded and suspended state (embedded type) with respect to the installation surface S is basically described. However, the container body 2 is provided with legs 26 (at least three or more) extending toward the floor surface F from the bottom of the installation surface S on which the high-temperature processing apparatus 1 (container body 2) is installed. It is also possible to install the high-temperature processing apparatus 1 at an appropriate height (installation surface S) by means of the legs 26 (this is called a stand type) , but this is a reference form related to the present invention. .
In addition , such a stand-type installation mode is a structure that can be easily adopted when the container body 2 is relatively small (smaller than in FIG. 1), etc., and FIG. A main body 2 (high temperature processing apparatus 1) and an operator M are shown .
