Definitions

  • the invention relates to a device for crushing small ice bodies, consisting of a housing without a bottom and cover, in which a shaft is mounted horizontally and rotatably, with knives on the shaft, counter knives attached to the housing and knives and counter knives a mutual distance, the have the desired degree of comminution.
  • Ice crushers of this type are known, for example, from DE-AS 19 44 142, 21 08 031 or DE-GM 69 21 181. These have a driven shaft on which a number of knives are fastened next to one another. Fixed counter knives are arranged between the knives. Knives and counter knives are designed as sickle knives with a plurality of tips to chop the ice bodies.
  • a disadvantage of the known devices is the need to provide a relatively strong drive for the comminution device, since the number of ice bodies chopped between the knife and counter knife is completely uncontrollable. For the same reason, the size of the crushed ice is also very irregular.
  • the mechanics and drive power of the known devices must be designed for loads that are rarely achieved in practice.
  • a commercially available device uses one Snail rotating in a vertical tube.
  • the tube is deep-frozen and is constantly sprayed with water, so that an ice layer is constantly formed.
  • This layer of ice is scraped off with the help of the screw.
  • the resulting ice snow is conveyed to a delivery device with the help of the screw.
  • the product produced in this way is cloudy ice snow, which in many cases is not accepted by the consumer.
  • the present invention has for its object to provide a device of the type mentioned, which allows the crushing of ice bodies with a defined grain size with the smallest dimensions and minimum power and at the same time can be expanded to practically any capacity.
  • This object is achieved in that a number of metal disks are attached to the shaft and that segments are cut out from a group of adjacent disks in such a way that a chamber for receiving exactly one ice body is created.
  • the individual ice bodies in the chambers which are formed by segment-like cutouts from the metal disks, are thus held, guided and comminuted on the fixed counter knives.
  • This has the advantages that the grain size is very uniform and the power requirement is minimal, since the size reduction takes place under defined conditions.
  • the fragments are clear if the ice bodies themselves were clear.
  • a plurality of chambers are regularly distributed on the disk circumference. It is also possible to arrange several chambers distributed over the length of the shaft. This will the shredding capacity is already increased without having to change the outer dimensions.
  • the chambers are distributed such that only one ice body is crushed at a time, the drive power for the knife shaft can be reduced to the absolute minimum without the capacity of the system suffering as a result.
  • the disks are preferably profiled on the circumference.
  • the ice bodies which are poured into the comminution device from above in a completely irregular manner, are oriented such that they fall into the chambers in the correct position. This is especially true when the ice bodies are approximately conical or cylindrical in shape.
  • unsegmented limiting disks can be arranged between the segmented disks.
  • roof-shaped covers fixed to the housing in particular, the loosely poured-in ice bodies are supplied to the crushing points or chambers in an improved manner.
  • the striking knives and the fixed counter knives are sharp-edged and toothed in order to be able to chop the brittle ice bodies more easily.
  • the fixed counter knives are preferably designed as cross-shaped crushing bones, which makes the grain even more uniform.
  • the distance between the rotating segment disks can be chosen larger than in the prior art.
  • the invention in the form of to be able to chop.
  • unsegmented limiting disks 8 are additionally arranged on the shaft 1. These form the end walls of the chambers 3 formed in the segment disks 2, so to speak.
  • the distances between two boundary disks 8 are bridged with the aid of roof-shaped covers 4, which can be placed in the simplest manner on fastening angles 7 in the housing 5.
  • FIG. 3 finally shows a system which has three comminuting sections lying next to one another.
  • the end faces of the segment disks 2 are provided with a profile 2.1 in order to be able to align the ice bodies 9 poured in from above so that they fall into the chambers 3 in the correct position. This is especially true when the ice bodies are approximately conical or cylindrical in shape.
  • the fixed counter knives can be seen between the segment disks 2, which are preferably designed as cross-shaped breaking bones 6 '.
  • the ice bodies hit them and are broken by the segment disks 2 or their sharp edges 2.2.
  • the chambers 3 receiving the ice bodies 9 are offset from one another both on the circumference of the segment disks 2 and over the length of the device, in such a way that preferably only one ice body is shredded between the segment disks 2 and counter knives 6, the (not shown) drive the shaft 1 only to the power required to crush a single ice cube and to prevent the device from blocking.
  • the defined position of the ice bodies during the shredding process supports the even grain of the end product.
  • the device of FIG. 1 consists of an approximately cuboid housing 5 without bottom and lid, but with a funnel-like filling device 5 'at the upper end.
  • a shaft 1 is mounted horizontally in the interior of the housing 5. The drive takes place via a motor, not shown.
  • Segment disks 2 are attached to the shaft 1 at regular intervals. Segments 10 are cut out from adjacent segment disks 2 to create chambers 3 which are matched to the size of the ice body 9 to be shredded. Each chamber can only hold one ice body 9.
  • edges 2.2 of the segmented disks 2 and the fixed counter-knives 6, which are active during comminution, are sharp-edged and toothed in order to make the ice bodies 9 lighter the housing and shaft can be easily extended.
  • the drive only needs to be strengthened if the extension means that more than one ice body is shredded between the knife and counter knife at the same time.
