Description

This utility model relates to the field of engineering, and specifically to equipment designed for the destruction and grinding of motor vehicles, components of electronic devices and military equipment.

These products are subjected to destruction, grinding and sorting in order to utilize constituent materials, both metallic and non-metallic.

A well-known mobile complex for the destruction and preliminary disposal of weapons and military equipment, including an assembly-disassembling technological line, a system of vehicles for transporting and deploying the line, handling equipment, as well as a container workshop with technological equipment, hydraulic shears and a baling press (RU 54251, class H01B 15/00; G01S 13/00; F41G 9/00.2006 g).

The disadvantage of this unit is the significant mass of equipment and the need for large production areas.

The closest analogue of the proposed technical solution is the “Press roller grinder” (RU 2116129, IPC 6 V02C 4/30, 1998). This unit consists of a hopper with a distribution device, inside which there is a roller unit, including drive lines of paired rolls with roll motors mounted in series on each pair of rolls, while the rolls are made with convex and concave planes parallel to each other and having transverse and longitudinal protrusions , conveyors and magnetic and pneumatic separation devices.

A disadvantage of the known device is that it does not provide for the destruction and grinding of large-sized products from plastic materials, for example, such as automobile bodies. Products made of plastic steel or copper alloys undergo strong bending, but do not collapse into small pieces, which further complicates their transportation and disposal.

This utility model has the task of ensuring the destruction of processed products into small parts.

The technical result is an increase in tearing moments in the process of disposal of equipment, vehicles.

The specified technical problem is solved in that in a device for destroying and grinding products, including a hopper with a distribution device, inside which there is a roller unit, including drive lines of paired rolls with roll motors installed in series on each pair of rolls, while the rolls are made with convex and concave planes parallel to each other and having transverse and longitudinal protrusions, conveyors and magnetic and pneumatic separation devices, according to a utility model It contains ferro-powder brakes installed between the roll motors and the roll pairs. In this case, the roller unit contains at least three pairs of rolls.

The introduction of ferro-powder brakes installed between the roll engines and the roll pairs into the device allows, after deformation of the product in the pair of the first drive rolls and its feeding into the next pair, to create tensile stresses and tearing moments in the product to be destroyed to break them into small parts. At the same time, the braking torque of the ferro-powder brakes can be easily adjusted at different speeds of the rolls, while conventional brakes: tape, drum with pads, etc. create a moment at a stop, this moment is unstable and

associated with wear. Conventional brakes cannot provide an adjustable braking torque during the rotation of the rolls at different speeds. Ferro-powder brakes, however, provide the possibility of creating in the rolled billet a stretch of adjustable size and destruction (rupture) of the billet between two adjacent pairs of rolls. It is advisable to install at least three pairs of rolls, which will ensure high-quality destruction of the product into smaller parts in comparison with the prototype.

A device for the destruction and grinding of products is illustrated by drawings, where figure 1 shows a diagram of a General view of the roller unit for the destruction and grinding of products, figure 2 - scheme of operation of the roller unit.

The device consists of a hopper 1 with a distributing device 2, inside of which there is a roller unit, including drive lines of paired rolls 3-4, 5-6, 7-8 and conveyors 9, for example belt. The rolls are made with convex and concave planes parallel to each other and having transverse and longitudinal protrusions. A pair of rolls through a gearbox 10 are connected to a ferro-powder brake 11. A pair of rolls 3-4 is connected in series with a motor 12 through a universal spindle 13, a ferro-powder brake 11, a gearbox 10 (for pairs of rolls 5-6, 7-8 there is a universal spindle, a ferro-powder, respectively brake and gear, not shown in Fig.). At the bottom of the hopper there are nozzles 14 that blow air that carries away dust, pieces of fabric, plastic into a dust collector 15. At the exit of the roller assembly there is an inclined conveyor 16 with a pneumatic separation device consisting of nozzles 17 and a dust collector 18. Next, a magnetic separation conveyor 19 and chambers for magnetic 20 and non-magnetic 21 pieces of metal.

The device operates as follows. Destructible product, such as a worn-out car, is fed into a pair of drive rolls 3, 4, which deform the product and partially destroy it. At

the need to destroy highly plastic materials, the engine of the rollers 3, 4 is turned off and the ferro-powder brake 20 is turned on for them. Rolling is carried out by the rollers 5, 6 when creating strong tension in the car when the rollers 3, 4 are in braking mode: when the ferro-powder brake 20 is on and the engine 18 is turned off. At the same time, the braking and breaking moments can be easily adjusted at different speeds of the rolls, while conventional brakes: tape, drum with pads, etc. create a moment when stopped, this moment is unstable and is the cause of severe wear. Conventional brakes cannot provide an adjustable braking torque during the rotation of the rolls at different speeds of the rolls. Ferro-powder brakes, however, provide the possibility of creating in the rolled preform a stretch of adjustable magnitude and destruction (rupture) of the preform between the pairs of rolls 3, 4 and 5, 6.

Further, the device operates according to a scheme known from the closest analogue.

Distinctive features ensured the solution of the problem and the technical result due to the possibility of creating high tensile stresses and tearing moments between the pairs of rolls of the unit.

The device is at the stage of a technical proposal.
