Description

The invention relates to the technique of grinding materials, namely, devices for grinding liquid and pasty materials used, for example, for oil works, and can be used in medical, chemical and other industrial sectors.

The purpose of the invention is to increase the productivity and quality of grinding materials

FIG. 1 shows a device for grinding materials, a section; in fig. 2 is a section A-A in FIG. one.

The device for grinding materials contains a hopper 1, verc .: a new part of the body 2 with vertical locking grooves 3, fixed knives 4 and 5 with protrusions 6 inserted with a gap in the vertical locking grooves 3 with the possibility of vertical movement and swing, feeder 7, elastic element 8, movable knives

9-11, installed with a gap on the pat-25 and fixed can be performed

The crown 12c washer 13 welded to it, which is mounted on the rotating body 14, the upper stationary millstone 15, rigidly mounted HJL upper part of the body 2, the lower rotating millstone 16 mounted on the rotating body 14 with the possibility of vertical displacement, the drive shaft 17 with an adjusting by device

in the form of a three-way screw with the left direction of the turns at the movable knife and with the right direction of the turns at the fixed knife for grinding the pasty material.

A device for grinding materials operates as follows.

The ground mass of the material is, po18, designed to regulate the gg of the pad on the sharp knives of the feeder 7, the pezazor between the millstones 15 and 16, the lower part of the body 19 with the receiving bowl and the discharge nipple connected to the upper part of the body 2 with hinged bolts 20.

The assembly of the device is as follows.

On the square cartridge 12, a feeder 7 with a square hole, an elastic element 8, a movable knife 9 with a square central hole, a fixed floating knife 4 with a circular central hole, a movable knife 10 with a square central hole, a fixed floating knife 5 with a circular central hole, having its protrusions 6 opposite the projections 6 of the stationary floating knives 4, and the movable knife 11 with a square central 6TV grains and the cartridge 12 is screwed into the rotating body 14, while the elastic element 8 s imaets. So all moving 9-11 and

It is cut, mixed and fed into the gap between the movable 9 and the fixed 4 floating knives, where the mass is again crushed. Further, the mass of material is pushed through the holes of the fixed floating knife 4 into the gap between the last and movable pump 10, where it is ground a third time, then the mass falls into the gap between the movable 10 and fixed 5 blades, where it is ground the fourth time. Further, the mass falling into the gap between the fixed 5 and movable 11 knives through the holes of the fixed Knife 5 is ground five times. The ground mass is ground for the sixth time in the gap between millstones 15 and 16. The ground material is finally crushed into the receiving bowl of the lower part of the body 19, and from the bowl through the discharge nozzle using the blades of the rotating body 14 into the container. Thus, in the proposed device have six steps

fixed 4 and 5 knives are pressed together. After assembling this unit, the upper part of the body 2 with the hopper 1 and the fixed millstone 15 are mounted so that the projections 6 of the fixed knives 4 and 5 fit into the vertical locking grooves 3 of the upper part of the body 2, after which the upper part of the body 2 is connected to the lower part of the body 19 with hinged bolts 20. If it is necessary to remove the upper part of the body 2 with the fixed millstone 15 and the bunker 1, it is sufficient to loosen the folding bolts 20 before this, and the assembly that includes the rotating body 14, the cartridge 12, the feeder 7, the elastic element 8, are movable 9-11 and fixed e 4 and 5 knives remain assembled. The design and shape of the movable and fixed knives can be varied depending on the properties of the material to be ground. For example, the design of knives as rolling, so

It is cut, mixed and fed into the gap between the movable 9 and the fixed 4 floating knives, where the mass is again crushed. Further, the mass of material is pushed through the holes of the fixed floating knife 4 into the gap between the last and movable pump 10, where it is ground a third time, then the mass falls into the gap between the movable 10 and fixed 5 blades, where it is ground the fourth time. Further, the mass falling into the gap between the fixed 5 and movable 11 knives through the holes of the fixed Knife 5 is ground five times. The ground mass is ground for the sixth time in the gap between millstones 15 and 16. The ground material is finally crushed into the receiving bowl of the lower part of the body 19, and from the bowl through the discharge nozzle using the blades of the rotating body 14 into the container. Thus, in the proposed device have six steps

chopping, i.e. three steps more than the famous.

Since the fixed blade is located on the movable knife, and the projections of the fixed blade with a gap are installed in the vertical locking grooves, the fixed blade is also, like the movable floating blade, i.e. they have the possibility of vertical movement and swing relative to all diameters. Therefore, it is possible to install alternately a large number of movable and fixed knives, pressed by one elastic element, while the middle knives work with both sides, and smoothly without jamming. If the fixed knives are not floating, jamming occurs , or shock vibration, as a result of which large gaps between the moving and stationary knives can be formed, and ets would adversely affect the performance and quality of grinding . Since the fixed and movable knives are floating, it is possible to significantly increase the number of movable and fixed knives, i.e. increase the number of grinding steps and increase the clamping force between the movable and fixed knives, and, consequently, dramatically increase productivity and improve the quality of grinding materials.

The proposed device also allows for easy disconnection of the upper part.

the case and the bottom, as it is not on the feeder lock-latch.
