Abstract

A DEVICE FOR CUTTING MATERIALS, comprising a housing, a pre-grinding body with a movable knife and a spring, an upper fixed millstone, a lower rotating millstone mounted with the possibility of vertical movement, and a feeder, characterized in that, in order to increase the productivity and efficiency of grinding on the body above the spring Two preliminary fixed knives — the scientific research institute and the lower one — are mounted on the pre-grinding body, and the feeder is equipped with two rotating knives — the lower one; between the auxiliary blades and an upper positioned above the upper knife support, wherein the upper blades are rotated relative to the lower knives in a horizontal plane.

Description

The invention relates to the grinding of materials, namely, devices intended for grinding of liquid and pasty materials. A mill is known that contains a loading device, a feeder, two stages of grinding bodies 1. However, this mill cannot provide high efficiency of grinding of pasty materials due to the presence of only two stages of grinding. Closest to the present invention is a device for grinding materials, comprising a housing, a pre-grinding body with a movable knife and a spring, and an upper fixed millstone. the lower rotating millstone, installed with the possibility of vertical movement, and the feeder 2J. The known device has low productivity and grinding efficiency, due to the presence. only two grinding steps. The purpose of the invention is to increase the productivity and efficiency of grinding. The goal is achieved by the fact that in a device for grinding materials, comprising a housing, a pre-grinding body with a movable knife and a spring, a stationary millstone, a lower rotating millstone installed with the possibility of vertical interlacing, and a feeder, two auxiliary mounts are mounted on the body above the spring of the preliminary grinding body. fixed knives - upper and lower, and the feeder is equipped with two rotating knives - lower, located between the auxiliary knives, and upper, located above the upper auxiliary knife, the upper knives being rotated relative to the lower knives in a horizontal plane. FIG. 1 shows the device, a general view in section; FIG. 2 is a section A-A in FIG. one; in fig. 3 Lazrez on BB in figure 1; in fig. 4 shows a section B-B in FIG. 2; figure 5 - feeder, general view; in fig. 6 is a view of FIG. five; in fig. 7 - auxiliary fixed knife. The device contains a feed funnel 1, the upper fixed auxiliary knife 2, an adjusting rubber gasket 3, the lower auxiliary knife 4, the upper part of the body 5 connected between the sab pin and the adjusting nuts 7, the feeder 8 with the fingers 9,. Spring 10 and the movable knife 11 mounted on the cartridge 12, which, in turn, is mounted on the rotating body 13, the upper stationary millstone 14 mounted on the upper part of the body 5, the lower rotating mill 15 mounted on the rotating body 13, the drive shaft 16 and p gulirovochnoe device 17 adapted for adjusting the clearance between the millstones hinged bolts 18, intended for connection to the lower portion of the housing top part 5, 19. The assembly device manufactured in the following order. Rotating millstone 15 and cartridge 12 are mounted on rotating body 13, upper fixed millstone 14 is mounted on upper part of body 5. Next, upper body of body is connected by folding bolts 18 to lower body 19, movable knife 11 and spring 10 are mounted on cartridge 12 the studs 6 are the lower auxiliary stationary knife 4 and the rubber adjusting pad 3, and the cartridge 12 is the feeder 8, after which the upper auxiliary stationary knife 2 is mounted on the studs 6, while the movable knife 20 of the feeder 8 passes through ithout figure hole of the upper auxiliary blade 2, as it mensche openings stationary knife. After this, the feed funnel 1 and adjusting nuts 7 are screwed in, thus forming a lock that keeps the feeder from axial displacement, as the lower rotary knife 21 of the feeder is larger than the figured hole of the lower and upper auxiliary knives 2 and 4. The adjusting nuts 7 tighten the screws until the workers touch the surfaces of the lower movable knife 21 of the feeder 8 with the working surfaces of the fixed auxiliary knives 2 and 4 so that no jamming occurs. The device is disassembled in reverse order. To remove the upper part of the body with the upper millstone, it is necessary to loosen the hinged bolts 18, and the upper part of the body 5 together with the funnel 1, the fixed millstone 14, the movable knife 11, the spring 10, the auxiliary stationary knives 2 ". The „„ - oo and 4 with the gasket 3 and the feeder 8 in the assembly lift up. In this case, the square section cartridge exits from the square section holes of the parts of the upper part of the device, which are assembled. The device works as follows: the mass is caught on the vertical fingers 9 and the upper movable knife 20 of the feeder 8, is preliminarily crushed, stirred and pushed by the upper knife 20 of the feeder 8 into the gap between this knife and the upper auxiliary stationary knife 2, where it is crushed a second time and simultaneously pushed into the gap between the auxiliary stationary knife 2 and the lower movable knife 21 of the feeder 8. Here the mass is ground to the third

being simultaneously and simultaneously pushed into the gap between the lower knife 21 of the feeder 8 and the lower auxiliary stationary knife 4, where it is ground four times and then ground, crushed in the gap between the upper stationary millstone 14 and the movable knife 11. Finally, the mass is ground in the gap between the upper stationary millstone 14 and the lower rotating millstone 15.

Thus, the proposed device contains 6 grinding stages. Auxiliary fixed knives, as well as feeder knives, rotated relative to each other, serve not only as an additional grinding body, but also as a body for the forced feeding of the ground mass from the loading funnel into the gap between the millstones along a helical line.

Since the device contains 6 grinding stages and at the same time, the ground mass is forced from the feed hopper to the millstones, and with the help of adjusting nuts creates a large clamping force, the productivity and efficiency of the grinding process increases. In addition, the reliability of the device is improved and the labor-intensiveness of grinding the millstones is reduced, i.e., on the cast millstone, grinding, for example, extra grinding of the millstone, is unnecessary, as the device design allows for greater thickness of the millstone, and this increases the durability millstones.
