Definitions

  • the invention relates to a device for producing flake ice from a freezable liquid, in particular water, with a cooling drum which is arranged in a trough and is coupled via a shaft to a gearbox and has a body which has a spiral channel along its surface has, which is covered by a cylinder jacket made of a material that is a good conductor of heat and is connected via a first and a second radial channel to cavities in the shaft, which are each connected to the hoses of a refrigerant circuit.
  • Such a device is known from DE-PS 16 01 084 and has a shaft with two bores, each of which emanate from the shaft ends and are used to connect the refrigerant circuit.
  • the connections for connection to the refrigerant circuit are located on both sides of the drum, which makes the connections to the refrigerator and the gearbox of the drive motor complicated.
  • the invention has for its object to provide a device of the type mentioned that can be easily connected on the one hand with the gearbox of the drive motor and on the other hand with the refrigeration machine.
  • the shaft has a blind hole extending from one side into which the radial channels open, that a fixed siphon tube protrudes into the blind hole and seals near the front end of the wall of the blind hole in the rotatable shaft is and that the siphon tube with one hose of the coolant circuit and the annular space between the wall of the blind hole and the outside of the siphon tube is connected to the other hose of the refrigerant circuit.
  • the annular space of the shaft is extended by a rotatable tube section which projects into the housing of a rotary inlet and has an effective seal with respect to the housing of the rotary inlet at its end which projects into the rotary inlet.
  • FIG. 1 shows the device according to the invention in a view from the front
  • Fig. 3 shows the device in an enlarged side view in section
  • Fig. 4 is a longitudinal section through the refrigeration drum of the device to illustrate the various channels for the refrigerant.
  • the device for producing flake ice is shown schematically in FIG. 1 in a front view poses. It has a water trough 1 which is filled to a level 3 with the liquid to be converted into ice, in particular water 2.
  • a cooling drum 4 Inside the tub 1 there is a cooling drum 4 with a cylinder jacket 5 made of a material which is a good conductor of heat, for example aluminum.
  • the body 6 of the cooling drum 4 is made of plastic and is provided along its surface with a spiral groove 7 through which a refrigerant flows.
  • the cylinder jacket 5 By evaporating the refrigerant, the cylinder jacket 5 is cooled, so that an ice layer forms on the outside thereof, which can be scraped off with the aid of a fixed scraper 8, which can be seen in FIGS. 3 and 3, from the cooling drum 4 which rotates counterclockwise in FIG.
  • the cooling drum 4 is arranged on a shaft 9 shown in more detail in FIG. 4, which projects out of the water tub 1 on the left and right in FIG. 1.
  • the shaft 9 is coupled via a flange 10 to a continuously variable transmission 11, through which the shaft 9 and thus the cooling drum 4 are driven at a speed of approximately 1.2 revolutions per minute.
  • the transmission 11 is in turn connected to a schematically illustrated electric motor 12.
  • FIG. 1 On the right side in FIG. 1 it can be seen how the right end of the shaft 9 is connected to a rotary inlet 13 which has a first refrigerant connector 14 and a second refrigerant connector 15.
  • the refrigerant is preferably introduced via the first refrigerant nozzle 14 for cooling the cooling drum 4, the second refrigerant nozzle 15 serving as an outlet.
  • FIG. 3 shows, compared to FIG. 2, further details of the construction of the device for producing flake ice.
  • a water solenoid valve 16 serves for the controlled inlet of the water 2.
  • the water solenoid valve 16 with the associated inlet tube is located near the bottom 17 of the water tub 1 in a side wall of the water tub 1.
  • the water inlet via the water solenoid valve 16 is automatically controlled after the device has been connected, a baffle plate 18, which is arranged in the vicinity of the water solenoid valve 16 inside the water pan 1, preventing the water from being strongly injected into the water pan 1.
  • An ice guard 19 can also be seen in FIG. 3, the front end 20 of which is at a distance of approximately 5 mm from the cylinder jacket 5.
  • the ice guard 19 allows the device to be switched off when the layer of ice on the cylinder jacket 5 becomes so thick that there is contact with the front end 20.
  • a water level float switch (not shown separately in FIG. 3) is provided within the water pan 1, by means of which the level of the water level is kept at a level at which approximately 2/3 of the cooling surface of the cylinder jacket 5 is surrounded by water 2.
  • a water drain tap is provided on the bottom 17, which is also not shown in FIG. 3 and which allows the dirty water to be drained off on the bottom 17 in order to clean the device.
  • the cooling drum 4 is shown enlarged with the associated shaft 9.
  • the left end of the spiral groove 4 in FIG. 4 is connected to a first channel 21 and the right end of the spiral groove 7 in FIG. 4 is connected to a second channel 22.
  • the channels 21, 22 extend radially through the body 6 of the cooling drum 4, which can also be seen in FIG. 2.
  • the shaft 9 driven by the gear 11 is rotatably supported in bearings 23 and 24, which are shown schematically in FIG. 4, in two opposite side walls 25, 26 of the water tub 1.
  • the right end of the shaft 9 in FIG. 4 opens into the fixed rotary entry 13, seals not shown separately being provided in FIG. 4 between the rotating and non-rotating parts.
  • the shaft 9 has a blind hole 27 which extends from the right end in FIG. 4 to the vicinity of the bearing 23 on the left side of the shaft 9. Both the first channel 21 and the second channel 22 open into the blind hole 27.
  • the diameter of the blind hole 27 at the left end is smaller than at the right end of the shaft 9.
  • a circumferential shoulder 28 is formed inside the shaft 9, against which a stuffing box 29 rests.
  • the stuffing box 29 is assigned an O-ring 30 so that a fixed siphon tube 31, which projects through the stuffing box 29 from the right in FIG. 4, is guided in a well-sealed manner.
  • the siphon tube 31, the diameter of which is smaller than the diameter of the blind hole 27, extends from the vicinity of the mouth of the first channel 21 through the blind hole 27 to the rotary inlet 13, where it merges into the first refrigerant nozzle 14.

Abstract

Un procédé de fabrication de glace en flocons avec un liquide susceptible d'être congelé comprend une cuve pourvue de parois latérales (25) et contenant un arbre rotatif (9) relié d'une part à un mécanisme d'entraînement et d'autre part à un tambour frigorifique (4). L'arbre (9) présente un alésage (27) à fond plein sur un côté, dans lequel aboutissent des canaux radiaux (21, 22). Un tuyau stationnaire à siphon (31) pénètre dans l'alésage à fond plein (27) et est scellé à proximité de son extrémité antérieure par rapport à la paroi de l'alésage à fond plein (27). Le tuyau à siphon (31) est en communication avec un tube du circuit de réfrigérant et l'espace annulaire (33) situé entre la paroi de l'alésage à fond plein (27) et le côté extérieur du tuyau à siphon (31) est en communication avec l'autre tube du circuit de réfrigérant.
