[0002]

[Prior Art]

 As shown in FIG. 1, the unevenness prevention means in the grain silo has a funnel-shaped bottom wall 10 of the bottle main body 1 which is formed in a tubular shape with the axial direction being the vertical direction and is mounted on the abutment a. On the outer peripheral side of the peripheral wall 11 and the ceiling wall 12, a partition wall 2 is provided in the shape of a double wall, and an airtight jacket 3 is formed between the partition wall 2 and the outer peripheral wall of the bottle main body 1. And the cold air generator 4 using the refrigerator are connected and communicated with each other to form a circulation path with the outward pipe 40 and the return pipe 41, and the cold air is circulated in the jacket 3 (to generate cold water. Then, the cold water may be circulated through the jacket 3), the outer peripheral wall of the bottle body 1 is cooled from the outer periphery, and the outer peripheral wall of the bottle body 1 is heated by the outside air to be packed inside. Prevents grain unevenness caused by raising the temperature of the grain It is way.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional means, since the outer peripheral wall of the bottle body 1 is formed as a double wall, the work for manufacturing the bottle body 1 becomes troublesome, the manufacturing cost increases, and it cannot be manufactured inexpensively. The jacket 3 becomes a substantial outer peripheral wall of the bottle body 1, and the cold air circulating in the jacket 3 exchanges heat with the outside, so that the thermal efficiency for cooling the grain inside the bottle body 1 is poor. There is a problem.

The present invention has been made in order to solve this problem that has occurred in the conventional means, in which the outer peripheral wall of the bottle body 1 is heated by the outside air temperature, and the inner portion of the bottle body 1 is heated. In order to prevent the deterioration of the temperature of the loaded grains by causing the deterioration of the grain, it is possible to make inexpensive at a low manufacturing cost without requiring troublesome work. However, the purpose is to provide a new means for improving the thermal efficiency for cooling.

[0005]

[Means for Solving the Problems]

 In the present invention, as means for achieving the above-mentioned object, the bottle main body 1 which is formed into a cylindrical shape with the axial direction being the vertical direction and is supported on the abutment a has a peripheral wall 11 inside thereof. On the peripheral surface side, a ready-made metal pipe P formed of a metal material having good thermal conductivity such as an aluminum alloy is formed in an annular shape along the inner peripheral surface of the peripheral wall 11 of the bottle body 1 and is continuously formed in a serpentine shape. Of the metal pipe P is supported by a bracket b provided on the inner surface side of the peripheral wall 11 of the bottle main body 1 so that a gap D exists between the peripheral wall 11 and the peripheral wall 11. Both the upper and lower free ends are penetrated through the peripheral wall 11 and protruded to the outside, and are connected to the cold air generating device 4 via the forward pipe 40 and the backward pipe 41, so that they are loaded inside the bottle body 1. The grains are arranged in a serpentine shape on the inner surface side of the peripheral wall 11 of the bottle body 1. Was allowed to cool by cold air passing through the inside of the metal pipe P, it is to raise the means to prevent the temperature on the grain temperature.

[0006]

[Action]

 According to the means of the present invention, the ready-made metal pipe P is attached to the inner surface of the peripheral wall 11 of the bottle body 1 via the bracket b while forming the metal pipe P into a serpentine shape along the inner surface of the peripheral wall 11 of the bottle body 1. It can be assembled to the bottle main body 1 by a simple work, and almost no work is required on the side of the bottle main body 1, so that it can be manufactured at low cost.

The metal pipe P, which is arranged in a serpentine shape, does not directly contact the peripheral wall 11 of the bottle body 1, but a gap formed by the bracket b between the inner surface of the peripheral wall 11 and the peripheral wall 11. As a result of being assembled in the state in which D is present, there is no direct heat exchange with the peripheral wall of the bottle body 1 that becomes hot, and the grains near the peripheral wall 11 that tend to heat up Since the metal pipe P is cooled directly by contact with the peripheral surface of the metal pipe P having a serpentine shape, the prevention of the unevenness caused by the temperature rise of the grain inside the main body 1 is achieved while maintaining good thermal efficiency. become able to.

[Effect of the device]

 As described above, in the grain silo prevention device according to the present invention, the ready-made metal pipe P is arranged in a serpentine shape on the inner surface side of the peripheral wall 11 of the bottle body 1, and the bracket b is attached to the inner surface of the peripheral wall 11. Via the inner wall of the peripheral wall 11 with a small gap D, and both free ends are provided on the outside of the bottle main body 1. Since the cold air or the cold water is circulated through the flexible pipe made of the metal pipe through the return pipe 41, the ready-made metal pipe P is molded into a flexible pipe along the peripheral surface of the bottle body 1. It becomes possible to assemble with simple work to install, and it becomes possible to install at low cost and at low cost.

The metal pipe P arranged in a serpentine shape does not directly contact the peripheral wall 11 of the bottle body 1 which is heated by the high temperature outside air, and a gap D is formed between them. Due to the existence, there is no direct heat exchange due to contact with the peripheral wall 11 of the bottle main body 1, and the heat conduction to the inside of the bottle main body 1 is blocked by using the gap D with the peripheral wall 11 as a heat insulating layer. Among the grains inside the bottle main body 1, the grains near the temperature-prone peripheral wall 11 tend to be effectively cooled, so that the peripheral wall of the bottle main body 1 is heated by the outside air. The prevention of the unevenness of the grain inside the bottle body 1 caused by the scraping can be achieved with the heat efficiency improved.
