Definitions

  • the invention relates to a machine for making cylinder-, blockor bar-shaped ice, comprising a water tank, in which have been mounted a number of freezing cores, each of which consists of at least one tube and, for one or more cores, supply and/or discharge elements and, if necessary, collecting and distributing vessels for the freezing medium.
  • the cores which are dealt with in the Dutch patent specification No. 83,606, for instance, have been positioned on the bottom of the water tank, while the collecting or distributing vessels belonging to one or morecores and the common supply and discharge elements for the freezing medium have been fitted beneath the bottom plate of the water tank. In connection with this, the water tank cannot rest on the floor over a large area.
  • Another drawback is that in removing the blocks of ice from the water tank, the blocks of ice float on the water, in merely some of the blocks the water-filled bores are automatically emptied. In fact, after the blocks have been thawed off, a portion of the blocks of ice will float on the surface of the water in such a position that the mouth of their bore is turned towards the wall of the water tank where the blocks are removed; the other floating bars of ice lie in such a way that the mouth of their bore is turned away from the said wall of the tank.
  • the measure according to the invention causes that each group of cores with the corresponding parts, supply and discharge elements and the box-shaped body, forms a separate unit, also called a battery, which is easily handled and transported, and which is mounted in its entirety in the water tank, consequently this tank can rest on the floor with its bottom plate over the whole area of said plate, an insulating plate being inserted, if necessary. No stiffening elements are required on the bottom plate of the water tank for the prevention of sagging.
  • each core in the place where it passes through the wall of the boxshaped body is surrounded on the inside of this wall at I some distance by a heating element.
  • the bars of ice After having been thawed ed, the bars of ice are pushed up to the surface of the water in the tank by the upward thrust and removed from the water tank near one of the walls of the water tank. After reaching the surface of the water, the bars of ice, which have a bore closed at least at one end, to wit in the place where the freezing core was present during the freezing process, can now be drawn over the respective w all of the water tank in two opposite positions, viz. with the mouth of the bore turned towards the middle of the tank or with the mouth of the bore turned away from the middle of the tank. In the former case, as the bar of ice is drawn over the wall of the tank the bore will empty itself owing to the inclined initial position of the bar.
  • the bore will not empty itself, so that the water present in it will flow oif outside the water tank, which involves a loss of generated cold.
  • the freezing core(s) has (have) been positioned so as to be slightly inclined towards the side of the tank where the blocks of ice or the like are removed.
  • the angle of inclination of the core(s) relative to the vertical is 4 to 6.
  • the exclusive right also covers a box-shaped body to be used in the machine described, characterized by at least one tubular element on one of the walls, which element passes through this wall and is connected with supply and discharge elements accommodated in the box-shaped body and belonging thereto, while a collecting or distributing vessel may be mounted in between, the box-shaped body being provided on another wall with fastening elements and at 'least one passage for the said supply and discharge elements.
  • FIG. 1 shows a group of freezing cores according to the invention
  • FIG. 2 gives a vertical cross-section through a boxshaped body
  • FIG. 3 shows a water tank, partly in cross-section, in which a number of box-shaped bodies have been accommodated.
  • the reference numeral 1 denotes the water tank. Said tank rests with its bottom plate 2 on the floor 4 of the premises, under insertion of an insulation plate 3.
  • this tank 1 which during operation is filled with water, a number of freezing cores 5 are mounted, each of which consists of a group of hollow tubes 5' closed at the top.
  • a number of freezing cores 5 are mounted, each of which consists of a group of hollow tubes 5' closed at the top.
  • ice will be formed around and between the tubes of a core, in the shape of a bar of ice 6 surrounding the core (FIG. 2).
  • a more detailed description of said formation of bars of ice is to be found in the Dutch patent specification No. 83,606.
  • each core may also consist of a single tube, which is the case eg in an ice generator for small pieces of ice, called crushed ice.
  • the tubes need not be parallel to each other.
  • each core 5 associated with each core 5 is a vessel 7 with a supply pipe 8 and a discharge pipe 9 for the circulation of the freezing medium.
  • the supply and discharge of said medium to the separate cores may also be chosen so that the vessel 7 can be omitted.
  • the cores 5 present in the water tank 1 are divided into groups, one of which is shown in F I.
  • Said group comprises six freezing cores. It is evident that a group may also comprise a smaller or a larger number of cores.
  • the six cores of the group here shown pass through a wall 10 of a boxshaped hollow body 11, in which the vessels 7 and the supply and discharge elements belonging to the cores have been accommodated.
  • this group of cores with the box-shaped body 11 forms a structural unit, which may be built up separately and may be mounted separately in the water tank.
  • Said structural unit which is to be called a battery hereinafter, is mounted on the wall of the tank 1 by the use of a fastening method known per se, e.g.
  • the wall of the tank has one opening through which the supply and discharge pipes for the medium to be employed in the freezing process are adapted to pass.
  • the supply and discharge pipes for the medium to be employed in the freezing process are adapted to pass.
  • a further advantage is the improved transportability of the whole machine.
  • the batteries and the tank can be transported separately to the destination, and there the machine can be assembled.
  • the number of batteries for a tank may be chosen at will and that the positioning of the batteries depends on the dimensions of the batteries as compared with those of the water tank.
  • two aligned batteries may be fitted on two facing sides of the water tank.
  • each core is surrounded, in the place where it passes through the wall of the boxshaped body, on the inside of said wall at some distance by a heating element.
  • this heating element is an annular tube 13, which has been fitted around the group of tubes of each core and which is equipped with supply and discharge pipes 14 and 15. During operation, a liquid which has been heated sufficiently to prevent the formation of the bulges in question is passed through this circuit.
  • Each of the two carrier systems is formed by an endless chain 19 parallel to the adjacent wall of the tank, one of which chains is shown in FIG. 3. Said endless chain 19 passes over two chain wheels 20. Since the chain wheels of the two carrier systems, which are supported on the wall of the tank facing the wall where the ice is removed, are mounted on one shaft, the two chains of the two carrier ssytems are synchronized in relation to each other. Each endless chain has been fitted in such a way that one part 19a runs above the surface of the water, while the other part 1% moves slightly beneath the surface of the water. The surface of the water 16 is kept at a constant level by means of a float not shown in the drawing.
  • a carrier 21 transverse to the direction of the partitions 17 and extending over practically the whole surface of the water.
  • Said carrier which during operation, as the two endless chains 19 are moved e.g. in the direction indicated by the arrow, at one moment will move through the water and at the next moment above the surface of the water, during its movement through the Water will take along all bars of ice 18 floating on the surface towards one of the sides of the tank.
  • Fitted on this side is the balancing member 22, against whose incline the bars of ice 18 are pushed by the carrier 21. When the bars have got far enough beyond the fulcrum 23, the balancing member 22 will tip over into the dotted position, the bars sliding off the balancing member outside the water tank.
  • the box-shaped bodies 11 have been mounted in the water tank so that the axis of each core 5 takes up a position slightly inclined towards the tank side on which the balancing member 22 has been fitted. Said measure ensures that the bars of ice after their detachment from the cores will reach the surface of the water by the route indicated by a dotted line in FIG. 3 and will all take up such a position that the mouth of bore 24 lies on the side turned away from the balancing member 22.
  • An effective inclination of the axis of the core has been found to be one deviating between 4 and 6 from the vertical.
  • a machine for making cylindrical, rectangular, or bar-shaped blocks of ice having a plurality of elongated bores therein which are closed at one end and open at the other end thereof comprising a water tank, a plurality of core units disposed within said tank and secured in fixed position therein to a wall of said tank, each of said units comprising a water-tight housing having a top wall and a vertical end wall by which said housing is secured in Water-tight relationship to said tank wall, aligned openings in said vertical wall and said tank wall, a plurality of freezing cores carried by said housing and projecting upwardly through said top wall, each of said cores consisting of a plurality of freezing tubes arranged in a group, circulation ducts disposed within said housing in communication with said freezing tubes, said ducts being adapted to alternately provide circulation of a freezing medium and a thawing medium through said freezing tubes, said ducts terminating in pipes which extend out through said aligned opening for connection to sources of freezing and thawing medium
