Description

Technical Field

[0001] The utility model relates to the technical field of snow melting machines, in particular to a refrigeration system with front-end supercooling for snow melting machines. Background Art

[0002] A typical refrigeration system consists of a compressor, condenser, throttling device, and evaporator. The pipe connecting the compressor and condenser contains high-temperature, high-pressure refrigerant gas. This high-temperature, high-pressure refrigerant gas must pass through the condenser to dissipate heat through forced convection and return to a normal-temperature, high-pressure liquid. The temperature corresponding to the pressure of the saturated refrigerant gas in the pipe between the compressor and the condenser is called the exhaust temperature. When the condenser is constant, the higher the exhaust temperature, the worse the cooling rate of the refrigeration system, and vice versa.

[0003] like Figure 2 As shown, a closed snow melter is a machine with a storage barrel and a refrigeration cylinder separated. There is a metal feed pipe connecting the storage barrel and the refrigeration cylinder. When the raw materials are added to the storage barrel, they will flow into the refrigeration cylinder through the feed pipe. The surface temperature of the refrigeration cylinder is relatively low during the refrigeration process, about -15°C, while the freezing point of sugar water is about -2°C. Therefore, the feed pipe may freeze during the use of the machine. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to provide a refrigeration system with front-end supercooling for a snow melter.

[0005] The specific solution of the utility model is: a refrigeration system with front-end supercooling for a snow melt machine, including a condenser, a refrigeration cylinder, a compressor, a capillary tube and a storage barrel. A feed pipe is provided between the storage barrel and the refrigeration cylinder. Several circles of heating pipes are wound around the outside of the feed pipe along the length direction. The inlet end of the heating pipe is connected to the exhaust end of the compressor through a pipeline, and the outlet end of the heating pipe is connected to the inlet end of the condenser.

[0006] Furthermore, the heating tube is a copper tube.

[0007] Furthermore, the heating tube is wound 2-5 times.

[0008] Furthermore, a plurality of evaporation tubes are wound around the outside of the refrigeration cylinder, the outlet end of the evaporation tube is connected to the suction end of the compressor, and the capillary tube is connected between the inlet end of the evaporation tube and the outlet end of the condenser.

[0009] Compared with the prior art, the utility model has the following advantages: the useless heat generated by the refrigeration system is converted into useful heat for thawing, which not only achieves the purpose of antifreeze of the feed pipe, but also improves the efficiency of the refrigeration system; when the machine is refrigerating, the surface temperature of the feed pipe is low, while the temperature of the heating pipe is high to heat the feed pipe and play an antifreeze role; when the refrigeration stops, the surface of the feed pipe returns to normal temperature, and the surface of the heating pipe also gradually cools down to normal temperature, which will not cause the raw material temperature to be too high.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0014] See also Figure 1 The present embodiment is a refrigeration system with front-end supercooling for a snow melter, comprising a condenser 6, a refrigeration cylinder 3, a compressor 5, a capillary tube 7 and a storage barrel 1. The outside of the refrigeration cylinder 3 is wound with 2-5 turns of an evaporation tube 4, the outlet end of the evaporation tube 4 is connected to the suction end of the compressor 5, and the capillary tube 7 is connected between the inlet end of the evaporation tube 4 and the outlet end of the condenser 6. A feed pipe 2 is provided between the storage barrel 1 and the refrigeration cylinder 3. The outside of the feed pipe 2 is wound with several turns of a heating tube 8 along the length direction. The inlet end of the heating tube 8 is connected to the exhaust end of the compressor 5 through a pipeline, and the outlet end of the heating tube 8 is connected to the inlet end of the condenser 6.

[0015] Furthermore, the heating tube 8 is a copper tube.

[0016] The working principle of the present invention is as follows: When the refrigeration system is operating, the exhaust temperature of the compressor 5 is relatively high. The high-temperature exhaust first passes through the heating pipe 8, which heats the feed pipe 2, thereby preventing the feed pipe 2 from freezing due to excessively low temperature. When the refrigeration system stops, the compressor 5 also stops operating, and the heating pipe 8 gradually cools to room temperature, thereby ceasing to heat the feed pipe 2 and preventing the raw material temperature from being excessively high. The improved structure of the present invention is significantly effective and the improvement cost is low.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
