Description

FS / E.1

The invention relates to a device for grinding bulk materials, mainly cereals, and can be applied in the construction, animal feed and other industries.

The purpose of the invention is to increase productivity and reduce the energy intensity of the grinding process.

FIG. 1 shows a rotary chopper, general view; in fig. 2 - section aa

The source material through the feed funnel 6 is loaded into the rotor 12, where under the action of centrifugal forces through the vertical grooves 13 is ejected onto the inner surface of the housing between the fixed legs 2. Particles larger than the specified size remain in the groove 13 on the surface of the movable blade 14 of the rotor and move with him on the body before meeting with the next fixed knife.

and carried down through the through vertical channels 16. The blades 15 rotate the rotor to suck the air from the atmosphere, tear the holes 5 in the housing and through the through channel 16 feed it down, catching particles of the crushed product on the way. From the conditions of the normal discharging of the crushed product, the channels 16 are made in the section expanding downwards. To regulate the air flow rate, the holes 5 overlap the shutters 4 of the disc 3. By turning the movable disc 3 in the direction of the arrow (Fig. 6), the curtains 20 open (or close) the inlet 5, thereby increasing (or decreasing) the air flow consumed by the fig. one; in fig. 3 shows a section BB in FIG. 2; 10 The crushed particles are picked up in FIG. 4 is a view of B in FIG. 1. by the shower flow created by the blades 15,

The rotary chopper comprises a conical housing 1, on the inner surface of which fixed blades 2 are mounted vertically. In the upper part of the housing there is a movable disk 3 with shutters 4 overlapping the air inlets 5 on the housing 1 and a feed funnel 6 consisting of a conical and cylindrical parts. The housing 1 is coaxially placed on the cylindrical chamber 7 with discharge vanes 8. Between the detachable parts of the chamber there is a bottom with perforations in the form of windows 9, and on the side surface of the chamber 7 there is a discharge window 10 communicated with the discharge port 11. The conical surface of the housing is 1-25 th axial fan. Further, part of the lower part of it may be moving particles, the lower

but connected to the chamber 7 either by means of the blades 15 and the knives 14 through the unloading of the flange attachment, which allows the body 1 to be vertically displaced relative to the fixed chamber 7 (for example, by means of adjusting bolts).

A conical rotor 12 is installed coaxially in the housing; it is made in the form of a cup, which is perforated on the outer surface by inclined vertical grooves 13, on one side of which are placed knives 14, and on the other, blades 15. The blades 15 are inclined and bent in the upper part in the direction of rotation of the rotor , while they form, together with the rotor, an axial fan. Each pair of knife-blade of elevation 40 develops on the surface of the rotor an insulated through channel 16, which directs the air-product flow from top to bottom. The inclined grooves 13 alternate with through vertical channels 16 and are also isolated from one another.

Chamber 7 is designed to take the ground product from a moving air product stream and then

thirty

The nozzle 11, and part together with the air flow enters through the loading openings 9 into the chamber 7 and is discharged out of its limits through the opening 10 going out into the discharge nozzle 11.

Moving the feed funnel 6 along the vertical axis of the rotor allows the gap between its cylinder, the curvature and the cone 17 to vary, and thereby adjust the feed funnel capacity or the load of the electric motor on the chopper drive.

The grind size is controlled by the height of the fixed knife 2 above the inner surface of the housing 1.

Invention Formula Rotary chopper, containing 45 split housing with knives on the inner surface, a rotor in the form of a glass with through grooves, between which are placed knives, hopper and unloading its evacuation through the window 10 and the branch pipe 11.pipe, characterized in that, with the aim Windows 9, concentrically positioned to increase productivity and reduce on the upper surface of chamber 7, are the energy intensity of the grinding process, the rotor with the continuation of through vertical channels 16. The discharge vanes of chamber 7, together with the rotor blades 15, form a unified discharge system, surrounded by blades obliquely mounted after the knives and forming the through channels along the rotor, while the blades in their upper part are bent into the original material through the hopper 6 is loaded into the rotor 12, where under the action of centrifugal forces through the vertical grooves 13 is thrown onto the inner surface of the body between the fixed-legs 2. Particles larger than the predetermined size remain in the groove 13 on the surface of the moving knife 14 of the rotor and move with it along the body until they meet with the next fixed knife.  The crushed particles are picked up by the air flow created by the blades 15, and carried down through the through vertical channels 16. The blades 15 rotate the rotor to suck air from the atmosphere through the holes 5 in the housing and through the through channel 16 feed it down, trapping particles of crushed product on the way. From the conditions of the normal discharging of the crushed product, the channels 16 are made in the section expanding downwards. To adjust the air flow rate, the holes 5 overlap the blinds 4 discs. 3. When the movable disk 3 is rotated in the direction of the arrow (Fig. 6), the shutters 20 open (or close) the inlet 5, thereby increasing (or decreasing) the air consumption consumed by the axial fan. Then a part of the ground particles is ejected from the bottom part of the blades 15 and knives 14 through discharging The nozzle 11, and part together with the air flow enters through the loading openings 9 into the chamber 7 and is discharged out of its limits through the opening 10 going out into the discharge nozzle 11. Moving the hopper 6 along the vertical axis of the rotor allows the gap between its cylindrical part and cone 17 to change and thereby adjust the hopper's throughput or the degree of loading of the electric motor on the chopper drive. The grind size is controlled by the height of the fixed knife 2 above the inner surface of the housing 1. Invention Formula Rotary chopper, which contains a split housing with knives on the inner surface, a rotor in the form of a glass with through grooves, between which are placed knives, a hopper and unloading provided with blades, inclined after knives and forming through channels along the rotor, while the blades in its upper part are bent in on baking full evacuation of the crushed-to-it rotation, between the detachable part of the product. The grinder works as follows. The hulls of the case are mounted with a perforated bottom, and the lower part of the case has unloading vanes. In the rotational direction, a perforated bottom is mounted between the detachable parts of the case, and the lower part of the case has discharge vanes. /five fzg.2 Bb Fig.Z Type B Fi.Ts
