Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cooling tank with an open top surface, and is particularly characterized in that the tank is provided with an elevating plate.

(Prior Art) Normally, a water-cooled cooling tank has an opening at the top, through which stored materials can be taken in and taken out. Similarly, in an air-cooled cooling tank where stored materials are frequently taken in and taken out, the upper surface is opened and this portion is used as the entrance to take in and take out the storage tank in order to prevent the cooling effect from deteriorating.

In general, the above-mentioned type of cooling tank is used, for example, as a tofu cooling water tank in tofu manufacturing equipment or as a cooling tank in which stored materials are manually taken in and out, such as in an ice cream stocker, but the depth of the tank is within a certain range. In other words, because the reach of human hands is limited to the bottom of the tank, all of them are small and have small capacity. (Problems with the conventional technology) For these reasons, conventional cooling tanks Its range of use is limited due to its low cooling and storage capacity, and this is also a factor in suppressing the sales and production volume of stored products.
In particular, with water-cooled cooling tanks, workers had to immerse their arms in cold water every time they took out or put stored materials in, which not only led to poor working conditions, but also caused problems such as frostbite.

Of course, there has been a desire for the development of a cooling tank with a large capacity that allows for easy loading and unloading of stored materials, but as mentioned above, this type of cooling tank has a limited depth. If you want to increase the capacity of the tank, you will inevitably have to increase the planar shape, and if you want to make it easier to take in and out the stored material, you will have to make the tank shallower. In the end, the cooling tank had to be made smaller because its efficiency decreased and its function as a cooling tank was impaired.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned points, and is provided with an elevating plate in a cooling tank, and this elevating plate appears to be the bottom surface of the upper surface. By placing the cooling tank on top and raising it, the apparent depth of the cooling tank can be adjusted, making it easier to take in and take out the stored items, and further making it possible to deepen the cooling tank and increase its capacity. It made it possible.

(Example) The present invention will be specifically described below based on the illustrated example. Figure 1 shows an example of a tofu cooling water tank.
Tube number 1 in the figure is the cooling tank.

2 is an elevating plate. The cooling tank 1 cools and stores tofu, and is basically constructed in the same way as a normal tank of this kind except that it includes a lifting plate 2 and a lifting mechanism 3.

That is, a cooling pipe 4 is installed inside the tank to cool the water contained therein, and a refrigerator 7 consisting of a compressor 5, a condenser 6, etc. is connected to this cooling pipe 4. A refrigerant is circulated between the refrigerator Ia7 and the cooling pipe 4. The lifting plate 2 functions as an apparent bottom of the cooling tank 1, and the stored material A such as tofu is placed on top of the lifting plate 2.
It is now possible to post.

In particular, this elevating plate 2 is movable up and down.

It is raised and lowered by a lifting mechanism attached to the cooling tank 1. In addition, the figure shows an example in which the cooling pipe 4 is buried inside the cooling tank 1. This is a cooling tank 1 and a lifting plate 2.
In view of the fact that the elevating plate 2 is internally provided, the purpose is to prevent the accumulated material A and the like from coming into contact with the cooling pipe 4 when the elevating plate 2 is raised and lowered, and to increase the internal volume.

By the way, there are no particular limitations on the mechanism for raising and lowering the lifting plate 2; any mechanism that can raise and lowering the lifting plate 2 at an appropriate speed is sufficient. Figures 2 and 3
The figure shows an example of this, and the lifting arm 8 is placed under the lifting plate 2.
is provided, and by raising and lowering this lifting arm 8, the lifting plate 2 is raised and lowered.

That is, in the figure, reference numerals 9a and 9b are drive shafts, and 1o is a cylinder. The drive shafts 9a and 9b reciprocate at an angle of about 90 degrees, and the rotational force raises and lowers the lifting arms in a range from horizontal to vertical. Lifting arms 8a and 8b are attached. The drive shafts 9a and 9b also have gears 11a.
, 11b are attached, and these two mesh with each other so that when one drive shaft is rotated back and forth, the other drive shaft is rotated by the same angle in the opposite direction. In the figure, a drive shaft 9a is rotated, and a crank arm 12 is attached to the drive shaft 9a, and this crank arm 12 is connected to the plunger 1 of the air cylinder IO.
3, and a crank mechanism is configured between the air cylinder lO and the crank arm 12. In the figure, when the air cylinder 10 is extended, the drive shaft 9a rotates clockwise, and this rotation causes the lifting arm 8a to rise, so the lifting plate 2 rises, and when the air cylinder 10 is contracted, the drive shaft 9a rotates clockwise. As it rotates counterclockwise, the elevating arm 8a is brought down and the elevating plate 2 is lowered.

(Effects of the Invention) As described in detail above, the present invention provides a cooling tank with an internal elevating plate, which appears to be the upper bottom surface, and which is raised to an appropriate height to store water. For example, in the case of a cooling water tank, the stored items are pushed up above the water surface, eliminating the need for workers to put their arms into cold water, eliminating the risk of frostbite, etc. This improves working conditions, and since the cooling tank can be made deeper than the length of the worker's arm, the capacity of the cooling tank can be increased accordingly.
