EXTRAORDINARY

The utility model relates to devices for raw materials, for example, grain, oilseeds, in tmcTHocTM rapeseed, and can be used. in food, feed, chemical and other industries.

Known multi-chamber mill according to, No. 980823 В 02 С 7/00, 1Ш2, comprising a housing with partitions and a shaft installed in a shaft with boards having concentrically located rectangular plates located in the gaps between the plates mounted on the partitions, and the plates located along an arc of a circle at a distance from each other. The material is crushed sequentially in grinding chambers formed between the disks and partitions, and the sizes of the crushed particles (grinding module) decrease as they transition from chamber to chamber

The disadvantage of this device is that the grinding process is carried out due to the impacts of the working bodies on the material being ground, which results in regrinding, and timely output by the fractional sizes of the finished product is not a prerequisite40TpeHo In addition, the output; the device is limited in time by passing one -,. of the volume of grinding material sequentially through all chambers,

The closest technical adherence to the claimed device is the device selected as a prototype for grinding grain (a.s. 1196025, B02 C 7 / W, 1965 hL, including a case in which two disks are mounted horizontally and reliably with the possibility of hitting in opposite sides with alternating annular protrusions that are in radial section

have the shape of an isosceles trapezoid, more often their base

facing the gfotivolashashaf disk, as well as through grooves in the annular protrusions are filled in the radial direction.

The processed material, passing through the sarpysotmnH nozzle into the grinding chamber between the disks that rotate in opposite sides, passes from the center along the radial through grooves on the annular protrusions under the action of the centrifugal force to the periphery. Grinding occurs using. for example, grains, the edges of adjacent through grooves on cutting pairs formed by adjacent rows of annular protrusions of opposing disks, with a degree of grinding the device equipped with a set of replaceable calibrated adjusting shafts | Adok, which are installed with drives.

A disadvantage of the known device is the following; In the grinding process in this technical solution, the size of the finished product (grinding module) depends on the gap between the disks, which is controlled by the vertical disinfecting of the upper disk by a series of adjusting gaskets, which does not require a gap between the disks of the device, and the space between the disks of the housing is not used. % The device’s performance depends on the peripheral speed of only two enemies 1 $ Yhei towards each other disks with working op1: ani and the number of through radial grooves in the ring protrusions.

The goal of the problem, which the claimed swaddling model is aimed at, is to increase the productivity and versatility of the grinder.

The totality of these existing signs complement, develop and clarify more private distinctive signs that are aimed at those who have solved the same problem.

Pieces: those of the common outlet pipe from the main and additional chambers located in the nsh pivotal Partition in the form of a sieve allows to increase the grinder's versatility, since it contributes to the production of either chopped shredders containing parts of different sizes, or one of them with a large size. According to the information available to the authors, the coherence of the essential features that transports the claimed utility model with the soup is not known from the prior art, which allows us to conclude that the utility model meets the novelty criterion. The set of essential features characterizing the utility model can, in principle, be reused in food, feed , chemical and other areas of performance for grinding bulk materials. The additional chamber and outlet pipe with a movable partition allow to grind an additional volume of bulk materials: with improved production of crushed particles of various large cm, which ensures the achievement of the goal - increased productivity and versatility of the device and: allows us to conclude that the utility model meets the criterion of industrial applicability. GyiqHocTb of the claimed solution is illustrated by the drawing, where on. ig. I depicts a universal chopper, an abundant look. ; Universal shredder SOSTOI1R from a fixed housing I with a loading 3 and outlet | dy pipe 10, inside of which along the .ff4i.H th longitudinal is equal the Tjerørrdk 11. In case I, it is coaxial - / .. -. - two of the smallest horizontal disks were installed: the upper 6 and lower 16. the working surfaces of the 6.16 disks and the upper case cover 2 are full — the protrusions 7, 8, 9 and 12 are ringed, having in a radial, ..- ..... . | I.-. . -,. through grooves, the walls of which in this section have the shape of a trapezoid .-- h Steps 7 and 9 of the upper disk b, located on both sides of it, are between the protrusions 12 and 8 of the lower disk 16. and the screwed-in housing cover, respectively. Shzhny disk 16 is mounted on the flange of the hollow shaft 14, the upper disk 6 is on the flange of the shaft 15. The latter is located in the cavity of the shaft 14 aligned with it. In the upper part, the shaft 15 is hollow, and its cavity communicates with the main 13 and the additional working chamber 5 of grinding by radial windows 4. The chopper operates as follows. The grain loaded into the pipe 3, through the radial holes 4 in the hollow part of the shaft 15, is fed into the main 13 and additional 5 grinding chambers, and then into the space by disks 6 and 16 and the upper cover S and disk B. Moreover, b and 16 are lying They are facing towards each other, and cover 2 is fixed. Passing under the action of cenrobing forces along the radial through grooves on the ring outposts 7.8, 9 and 12, the grain is crushed by means of a cut on the cutter pairs formed by adjacent rows of elements. The crushed grain, exposed to the first pair of annular protrusions, moves under the action of centrifugal forces and five through grooves to the next rush couples. By the measure of passing grain to the periphery, the degree of its grinding increases, especially the fineness (grinding module) of the finished product when leaving the main 13l of an additional 5 chambers will be different. Due to the fact that the peripheral speed of the working bodies in the main. the chamber is larger (both disks with working bodies rotate), tjacTHubi loose bulk materials are more likely to interact with the living edges and the fineness of the finished product is .- - --- .. J -.- jA -. less than jh in the additional chamber, where only the rotary disk rotates and the peripheral speed of the working bodies doubles to obtain these grinding fractions separately or vice versa 1 to have the overall average fraction composition, it is necessary to use the movable partition II, made in the form of a sieve, placed in the outlet pipe 10 along Thus, by installing the longitudinal axis in tjTo, it was possible to divide the latter into two channels, and by pulling it out, make a common channel, and additionally separate small frash: from the mixture coming from measures 5, sifting through a sieve, An example of a specific implementation As an example of a specific embodiment, consider a grinder, in which case I is selected with a diameter of 0.5 m, the height of the body / 0.100 m, the height of the working area of the additional chamber .k 0.033 m. the grooves of the annular / protrusions of both chambers are the same and equal to 32. This ensures the performance of the main camera - 5 t / h, and the additional - -2 t / h.,. The lateral branch pipe has a rectangular cross-section of 0.5 mx X 0.1 m in size, and the movable partition П has the shape of a rectangle with dimensions of 0.25x0.5 m and mates with the housing in a radius of 0.25 m with a sieve diameter of 0, 25 mm, In the proposed device, compared with the prototype, productivity increases by 30%. 1 furthermore, the device provides at least the output of the grinding module without :: disassembling, the device (operational adjustment) -.
