Embodiment 1

[0020] Ejector pump liquid supply vertical cylinder ice machine (see figure 1 ), including a vertical cylindrical jacket type refrigeration evaporation icing cylinder 1, a cylindrical base 3 with an annular sump 2 under the icing cylinder 1, and a support rod 4 in the center of the cylindrical base 3 is connected to the cylindrical base 3 The connected bearing housing 5 has a bearing 6 in the bearing housing 5, an end cover 8 with an observation window 7 on the icing cylinder 1, or no observation window, and an electric reducer 9 is installed on the end cover 8, and the icing cylinder 1 The center has a rotary main shaft 10 whose lower end is supported by a bearing 6 and whose upper end is connected to the output shaft of the electric reducer 9. There is a cantilever 11 on the rotary main shaft 10, and an ice scraper 12 is installed on one end of the cantilever 11 to spray ice on the inner wall of the icing cylinder 1. The pouring pipe 14 of the ice water is connected with the...

Embodiment 2

[0030] The difference with Embodiment 1 is: the water pump 19 is connected with the seal joint 52 on the upper end of the water injection pipe 18 and the rotary main shaft 59 (see figure 2 ), the sealing joint 52 is sealed and connected with the rotary main shaft 59, and the upward part of the rotary main shaft 59 and the shower pipe 53 junction is a hollow structure, and 54 is a dynamic sealing ring, and the upper end of the rotary main shaft 59 can rotate in the sealing ring 54.

Embodiment 3

[0032] The difference with Embodiment 1 or 2 is: the air inlet of the horizontal low-pressure circulation barrel 24 back air outlet pipe 49 extends from the barrel wall of the horizontal low-pressure circulation barrel 24 on the upper part of the gas collection long disk 48 into the gas collection long disk 48 Inside, the air outlet of the horizontal low-pressure circulation barrel 24 return air outlet pipe 49 passes through the barrel wall on the upper part of the low-pressure circulation barrel 24 and links to each other with the suction pipe 50 of the refrigeration compressor unit (see image 3 , 4 ).

Description

Technical field: [0001] The invention relates to a vertical cylinder ice maker. Background technique: [0002] Existing vertical cylinder ice machines use a thermal expansion valve for liquid supply or a refrigerant power pump for circulating liquid. The thermal expansion valve is used for liquid supply, and the evaporative heat transfer efficiency of the freezing cylinder is low, and the ice making capacity is low; the refrigerant power pump is used for circulating liquid supply, and the power consumption is high, and the moving parts of the pump are worn, the failure rate is high, and the operating cost is high. high. Invention content: [0003] The object of the present invention is to provide a technical scheme of a vertical cylinder ice machine with ejector pump for liquid supply. The icing cylinder of the machine has high evaporation and heat transfer efficiency and strong ice making ability, which is beneficial to reduce power consumption; Economical, reliable and...
