Abstract

SHOCK CRUSHER, including a vertical cylindrical with reflective plates, on its inner surface, an impeller in the form of a disk, on which radial plates are installed by means of brackets, characterized in that the hole is V-shaped, the top of which is directed to the vertical axis of the disk, and the latter is inclined at the last. side mounted brackets.

Description

; The invention relates to devices for grinding materials and can be applied in the construction, mining and other industrial sectors.

The closest technical solution known is the impact crusher, which includes a vertical cylindrical body with reflective plates on its inner surface, an impeller in the form of a disk, on which radial plates are mounted by means of brackets.

The disadvantage of this design is the greater complexity of replacing the radial plates.

The purpose of the invention is to provide a quick replacement of the radial plates.

This goal is achieved by the fact that in a shock shotgun, including a vertical cylindrical body with reflective plates on its inner surface, an impeller in the form of a disk, on which radial plates are mounted by means of brackets.

i

in each radial plate there is a V-shaped through hole, the top of which is directed to the vertical axis of the disk, with brackets installed inclined in the same direction on the latter.

Figure 1 shows the crusher, the section; figure 2 is a top view of section A of the AA-A in FIG. 1; fig.Z - radial plate section.

with y

The crusher contains a cylindrical body 1 with a crush, carrying the feed funnel 2, discharge funnels

rs 3. In the center of the case, an impeller 4 is mounted, layers of a disk 5 with brackets 6. Arms. They are made in the form of rods of round rectangular or wedge section, inclined to the vertical axis of the disk. The brackets are equipped with radial plates 7 with V-shaped holes 8, the tops of which are directed to the vertical axis of the disk, while the length of the wall 9 of the bracket adjacent to the center of the impeller 9 corresponds to half of the 38 walls of the 10 and 1I holes. The surface of the disk 5 between the radial plates 7 is lined with sheets 12 of an abrasion-resistant material. Reflective plates 13 are fixed against the radial plates 7 on the crusher body, and an electric motor 14 is mounted on the outer side of the crusher body, which drives the impeller 4 into rotational movement through a wedge-drive gear. Impact crusher works in the following way. The initial product is fed through the feed hopper 2 into the center of the fast-rotating impeller 4 with the disk 5. The product is captured by the radial plates 7 and thrown radially by the centrifugal forces on the reflective plates 13. The particles of the product hit the reflective plates, are crushed and fall down where they are unloaded through the discharge funnels 3. When the impeller 4 rotates under the action of centrifugal force, the radial plates 7 are pressed tightly to the crown-ains 6. The radial plates 7 are fixed radially due to we also tilt the brackets 6 as well as the lining sheets 12 of the impeller disk 5 4. Installing the radial plates 7 on the brackets 6 the operation is not laborious and is done after removing the upper cover 2 of the crusher body. The absence of bolt joints facilitates the replacement of the radio plates that are removed from the bracket side of their slope. In case of wear of one working surface of the radial plate, it is removed from the bracket and turned over with the other side. In addition, the brackets, which are located in the radial plates, are protected from the effects of the material and the wear of the brackets is almost eliminated. The use of this crusher allows for quick replacement of the radial plates.
