Roller evaporator for a snow machine

Abstract

A roller evaporator for a snow machine includes an inner layer and an outer layer. The inner layer is fixed on a high pressure tube and a low pressure tube, and the outer layer corresponds to and rotates relatively with respect to the inner layer. A roller of the roller evaporator is divided into two layers, with the inner layer being installed and sealed on the high pressure tube. Therefore, an extremely good sealing effect is provided and refrigerant does leak out easily while making ice.

Description

BACKGROUND OF THE INVENTIONa) Field of the InventionThe present invention relates to a roller evaporator for a snow machine, and more particularly to a roller evaporator for a snow machine, which is used to make snow and is provided with an extremely good sealing effect.b) Description of the Prior ArtA so-called snow machine is used to make snow and an ordinary snow machine includes a compressor and a roller evaporator which is connected to the compressor through a low pressure tube and a high pressure tube, respectively. In the existing technology, the roller of an ordinary evaporator is one-layered, and refrigerant is sent into the roller by the high pressure tube and is then exported by the low pressure tube; whereas, the roller rotates around the high pressure tube and the low pressure tube (which are fixed). The roller, the high pressure tube and the low pressure tube are sealed by sealing washers; however, as pressure in the high pressure tube is very high, the sealing washers...

AI Technical Summary

Benefits of technology

The primary object of the present invention is to provide a roller evaporator for a snow machine, wherein the roller evaporator includes an inner layer and an outer layer. The inner layer is fixed on a high pressure tube and a low pressure tube, the outer layer rotates relatively with respect to the inner layer, and thermal grease is filled between the inner layer and the outer layer. Moreover, two ports of the outer layer are transfixed with sealing washers which are connected respectively with the lower pressure tube and the high pressure tube, and two sides of the sealing washers are provided respectively with a bearing. When refrigerant is ejected out from nozzles of the high pressure tube, a roller of the outer layer can rotate relatively with respect to an evaporation tank of the inner layer and a rotation speed can be increased that the refrigerant does not leak out. By the aforementioned technologies, the issues existing in the conventional snow machine that the pressure in the high pressure tube is very high and the sealing washers cannot be sealed tightly, which results in that the refrigerant can leak out easily when making the ice, can be solved, thereby achieving the practical progressiveness of the good sealing effect and of that the refrigerant does not leak out easily during making the ice, by separating the roller of the roller evaporator into two layers and installing and sealing the inner layer on the high pressure tube.

Problems solved by technology

The roller, the high pressure tube and the low pressure tube are sealed by sealing washers; however, as pressure in the high pressure tube is very high, the sealing washers cannot be sealed tightly, such that the refrigerant can easily leak out during making ice.
