Description

[Detailed description of the invention] [Industrial application field] This invention is used in the chemical food industry, particularly in fermentation tanks for miso, soy sauce, etc., and fermentation product storage tanks.
This invention relates to a reinforced plastic tank equipped with a cooling device (in the present invention, the reinforced plastic tank is simply referred to as a tank).

[Conventional technology]

Conventionally, to heat and cool the fluid inside a tank, a device is used that circulates hot or cold water by wrapping a pipe around the outer circumference of the tank, but in this case, the heating and cooling must be done through the pipe wall. Because the contact area of the pipe wall with the tank is small, heat exchange efficiency is low, and the fluid in the tank cannot be heated or cooled smoothly, resulting in high initial costs and high energy consumption, which reduces running costs. It also has the disadvantage of being expensive.

[Problem that the invention attempts to solve]

This invention was developed in consideration of the high running costs due to the energy consumption of the conventional tanks mentioned above.
Furthermore, in order to save energy, there is a strong demand from the fermentation industry for tanks equipped with heating and cooling devices that are low cost and consume little energy, and in response to this, we have developed a system that allows smooth heating and cooling of the fluid in the tank. As a result of intensive research aimed at obtaining a tank equipped with a low-energy heating and cooling system, it was finally confirmed that a tank could be obtained that would achieve the above objectives, and the present invention was completed. Ivy.

[Means for solving problems]

The present invention provides an enclosure consisting of a plurality of double-walled corrugated plates inside a tank, with one wall serving as the tank wall, and a plurality of additional parts are installed in the space surrounded by the corrugated plates and the tank wall. The flat part of the cylindrical pipe for heating or cooling with a cross section that is roughly divided in half is provided in contact with the corrugated plate on the liquid side of the tank (Figure 2), and the remaining space inside the corrugated plate is used as an air layer or a heat insulating layer. This provides a tank equipped with a heating and cooling device inside.

It is suitable to fill the heat insulating material layer with a heat insulating material such as urethane foam.

Furthermore, heating and cooling can be performed even more smoothly by applying a heat-insulating exterior to the entire outer circumference of the tank.

〔Example〕 Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention showing only the middle part of a tank equipped with a heating and cooling device inside.

Figure 2 shows an enclosure with one double-walled corrugated plate shown in Figure 1 and a tank wall on one side, with the flat part of a semi-cylindrical pipe through which hot and cold water runs touching the wall of the corrugated plate. Diagram when provided.

FIG. 3 shows a cross-sectional view of a case where a heating and cooling device is provided inside the tank and a heat-insulating exterior is applied to the entire outer periphery of the tank. Reference numeral 1 denotes a corrugated plate enclosure having a double structure with one wall serving as a tank wall, and a plurality of corrugated plates are provided along the outer periphery of the tank. Therefore, when stirring the fluid in the tank, turbulence is generated and the stirring effect is large.

In addition, in the semi-cylindrical heated water and cooling water passages inside the corrugated plate, the semi-cylindrical flat surface is in contact with the corrugated plate that is in contact with the fluid in the tank, so heat transfer efficiency is high and heating and cooling can be performed smoothly. There are advantages. 2 is the hot water and cooling water outlet. 3 is the hot water and cooling water inlet. 4 is an air layer or a heat insulating material layer in the inner space of the double-structured corrugated plate. 5 is a heat insulating material that covers the entire outer surface of the tank. 6 is the tank body. 7 indicates the fluid in the tank. The double-structured corrugated sheet of this invention uses the tank wall as one wall, and is integrally molded with a roughly half-split pipe enclosed within the corrugated sheet, so there is no inconvenience when cleaning the tank. do not have.

Urethane foam was used as the insulation material.

[Effect of idea]

The effects of the present invention are summarized as follows.

(a) In this invention, pipes for circulating hot and cold water are provided inside the tank, and the pipes for circulating hot and cold water are in contact with the fluid in the tank, and furthermore, there is a pipe for circulating hot and cold water and the tank body. The presence of an air layer or a heat insulating material layer is advantageous for heat radiation and heat absorption of circulating water.

(b) Since the corrugated plate having a double structure is present in the tank, it acts as a baffle plate for stirring the fluid in the tank, creating turbulent flow and having a large stirring effect.

(c) By insulating the tank body with a heat insulating material, the energy running cost of the present invention is further reduced.

(d) The corrugated sheet with a double structure of the present invention uses the tank wall as one wall, and the corrugated sheet is surrounded by an almost half-split pipe that is integrally molded, making it easy to clean the tank. Tank management is easy.
