Description

  The present invention relates to a drum evaporator for an artificial snow making machine, and more particularly to a drum evaporator for an artificial snow making machine that is used for producing artificial snow and has an excellent sealing effect.

  The artificial snow making machine is used for the production of artificial snow, and generally the artificial snow making machine includes a compressor, a drum type evaporator connected to the compressor via a low pressure pipe and a high pressure pipe, respectively. In the existing technology, the drum of a general evaporator is a single layer, the high-pressure pipe feeds refrigerant into the drum and outputs the refrigerant from the low-pressure pipe, and the drum is a pipe having the high-pressure pipe and the low-pressure pipe ( The drum, the high-pressure pipe and the low-pressure pipe are sealed by a packing washer. However, since the pressure of the high-pressure pipe is very high, it cannot be sealed with the packing washer, and the refrigerant is likely to leak during the ice making process.

  A main object of the present invention is to provide a drum type evaporator for an artificial snow making machine which has an excellent sealing effect used for the production of artificial snow.

  The drum evaporator of the present invention includes two layers, an inner layer and an outer layer, the inner layer being fixed on a high pressure pipe and a low pressure pipe, the outer layer corresponding to the inner layer and rotatable relative to each other, A heat conductive paste is filled between the inner layer and the outer layer, the low pressure pipe and the high pressure pipe are respectively connected to both ends of the outer layer via O-rings, and bearings are respectively installed on the outer sides of the O-rings on both sides. The When the refrigerant is ejected from the nozzle of the high pressure pipe, the outer layer drum rotates relative to the inner layer evaporation drum, and the refrigerant does not leak to the outside even if the rotation speed is increased.

  Due to the above-described technology, the drum evaporator of the present invention has a very high pressure pipe pressure of the artificial snow making machine existing in the conventional artificial snow making machine, so it cannot be sealed by the packing washer, Overcoming the problem of refrigerant leaking easily in the process, dividing the drum of the drum evaporator into two layers, installing the inner layer on the high-pressure pipe, and further sealing, excellent sealing effect, Refrigerant is unlikely to leak during the ice making process, providing practicality and inventive step.

FIG. 1 is a schematic diagram 1 illustrating an operation principle of the best embodiment of the present invention. FIG. 3 is a schematic diagram 2 illustrating an operation principle of the best embodiment of the present invention. It is sectional drawing which shows the structure of the drum type evaporator of this invention.

  1 and 2 are schematic diagrams 1 and 2 showing the operation principle of the preferred embodiment of the present invention. As can be clearly seen from these drawings, in the drum evaporator 120 of the present invention, the high-pressure pipe 102 and the low-pressure pipe 101 are communicated with both ends, respectively, and the refrigerant passes through the compressor 105 in the direction of the arrow. It is transported through the tube 102 to the drum evaporator 120. The artificial snow making machine has a housing 113 for sealing each operation member, a mounting base 114 for supporting the evaporator support 115, an evaporator support 115 used for mounting the drum evaporator 120, and the housing 113. A door 118 for opening the chassis, a chassis 111 for mounting the compressor 105, and a manufactured snow 112.

  Among them, a knife 117 for scraping ice generated on the outer surface of the outer drum 125 is installed outside the drum evaporator 120, and a water container 116 is installed below the drum evaporator 120. Is filled with water, and the water in the water container 116 becomes ice by the rotation of the drum evaporator 120. FIG. 3 is a cross-sectional view showing the structure of the drum evaporator of the present invention. As can be clearly seen from the drawing, the drum-type evaporator 120 for artificial snow making machine includes two layers, the outer layer is the drum 125, the inner layer is the evaporation drum 126, and the evaporation drum 126 is It is fixed on the high-pressure pipe 102 and the low-pressure pipe 101. In this embodiment, the low pressure pipe 101 and the high pressure pipe 102 are connected to both ends of the drum 125 through O-rings 121 and 122, respectively. Bearings 127 and 129 used for attaching the low-pressure pipe 101 and the high-pressure pipe 102 are respectively installed outside the O-rings 121 and 122 on both sides. The drum 125 can rotate.

  In this embodiment, in order to quickly derive the coolness in the drum evaporator 120 to the outer surface of the outer layer of the drum 125, a heat conductive paste 130 is provided between the inner drum 126 and the outer drum 125. Filled.

  The drum type evaporator 120 provided in this embodiment includes two layers, an inner layer and an outer layer, and the inner layer evaporation drum 126 is fixed on the high-pressure pipe 102 and the low-pressure pipe 101, but this may be fixed by welding. Since the heat conductive paste 130 is filled between the outer layer drum 125 and the inner layer evaporation drum 126, and the heat conductive paste 130 does not have any pressure, it may be simply sealed using O-rings 121 and 122. . The refrigerant 124 is ejected from the nozzle 123 of the high-pressure pipe 102, and the outer drum 125 is rotatable relative to the inner evaporation drum 126. Even if the rotation speed is increased, the refrigerant 124 does not leak to the outside.

  For this reason, as shown in all the drawings, when the present invention is used, the following advantages are surely present as compared with the prior art.

  Between the outer layer drum 125 and the inner layer evaporation drum 126 is filled with a heat conductive paste 130, and since the heat conductive paste 130 has no pressure, it can be easily sealed using O-rings 121 and 122. Good. In addition, the refrigerant 124 is ejected from the nozzle 123 of the high-pressure pipe 102, the outer drum 125 rotates relative to the inner evaporation drum 126, and the refrigerant 124 does not leak to the outside even if the rotation speed is increased.
