about

The invention relates to devices for grinding raw materials of plant and animal origin and can be used in the medical and other industries.

The purpose of the invention is to increase productivity.

1 shows a schematic of a chopper; figure 2 - section aa in figure 1; on fig.Z - scheme si, acting on raw materials during grinding; figure 4 - element of the grating drum, type A in fig.Z: figure 5 - section bB in figure 4.

The shredder contains a vertical cylindrical housing 1 with a boot

a branch pipe 2 and a grating-drum 4 with a drive 5 mounted on the shaft 3. The grating drum 4 is located vertically in the housing 1, inside it there is a coaxially mounted rotor b consisting of a horizontal disc 7 and vertically fixed on it along the periphery of the lamellar scrapers 8 evenly spaced around the circumference and serving to distribute the source material on the inner surface of the thermal drum 4. On the shaft 3 of the grating drum 4 inside the rotor 6, under the loading nozzle 2, the blades 9 are reinforced, which serve to feed the initial material on the lamellar scrapers 8 of the rotor 6. The housing 1 has the upper 10 and lower 11 covers with bearing supports 12 and 13. On the shaft 3, a grate 14 is planted, the upper part of which has a pulley 1.5 connected by a V-belt drive 16 with the pulley 17 of the drive 5, Inside the grate 14 on its ribs 18 is supported by a grating drum 4 with holes 19 and teeth 20 on its inner surface. A grated drum. 4 consists of a series of fast-growing sections, each of which is part of a circle with a central angle a. The sections are inserted with vertical edges into the guides 21 of the grate 14. The rotor 6 is placed in a grating drum 4 rotatably relative to it in a bearing support 22. Between the scrapers 8 of the rotor 6 and the teeth 20 of the grated drum 4 there is a gap of 2-3 mm. A pulley 23 is mounted on the upper part of the rotor 6, associated with a clinoreme transmission 24 with the pulley 17 of the drive 5. The clinorem transmissions 16 and 24 of the grate 14 and the rotor 8 have different gear ratios, therefore the rotation frequency of the pulleys 15 and 23 are different. A hopper 25 is attached to the lower lid 11 of the housing 1 for the use of the rubbed mass.

The grinder works as follows.

The source material is loaded through the pipe 2 on the top cover 10 of the housing 1 into the inside of the rotor 6. The blades 9 of the shaft 3 pieces of raw material are thrown to the periphery on the lamellar scrapers 8 of the rotor 6, which feed them onto the working surface of the grated drum 4. The pieces that hit the rotor disk 7 they are thrown to the periphery as well as to the lamellar scrapers 8. Under the action of centrifugal force, the pieces are pressed against the grating drum 4, forming a layer over its entire working surface. The rotor 6 and the grating drum 4 mounted on the supports 12 and 13 of the covers 10 and 11 and the support 22 have

the same direction of rotation from the pulley 17 of the drive 5, but due to the different gear ratios of the V-belt drives 16 and 24 there is a relative rotation between them. Therefore, a layer of pieces of raw material, pressed by centrifugal force to the grating drum 4, is shifted by scrapers 8, and this shift is performed against the tooth of m 20 of the grated drum 4. At the same time, fine chips, which are smaller than the sizes of the holes 19 in the grated drum 4, fly out of them under the action of centrifugal force in the windows of the grate 14 past its ribs 18.

Large pieces are rubbed on a grating drum 4 into fine chips, which through holes 19 and the grate 14 flies out onto the walls of housing 1. Co The wall of housing 1 is crushed — the mass slips into the hopper 25 under the action of gravity. When necessary, the grating drum sections need to be replaced 4 in the event of a breakdown or cleaning, they are inserted into the guides 21 of the grate 14.

The advantage of the proposed biological tissue shredder is that the grinding process is performed simultaneously over the entire cylindrical surface of the grating drum. In this case, a continuous and uniform supply of raw material to the working surface of the drum, its abrasion and removal of the crushed mass is carried out. This makes it possible to increase productivity and to obtain a homogeneous, wiped mass at the outlet of the grinder.
