Description

 I

The invention relates to the design of devices for the production of loading and unloading operations and can be used when loading and unloading bulk materials.

A device for loading and unloading bulk materials is known, comprising a reservoir equipped with one L1J conveyors arranged one above the other.

However, in this device, the direction of movement of the bulk material when it enters and leaves the tank is uniquely determined by the directions of entry of the conveyors into the tank, and the design of the device does not allow the material to change the direction of movement with one conveyor relative to the direction of movement by another conveyor, which forces the process of loading and unloading operations or move the device itself, or provide greater flexibility of the conveyors introduced into it, which is not always achievable. All this takes away the operational capabilities of the device.

The purpose of the invention is to increase efficiency by changing the direction of movement of the bulk material.

This goal is achieved by the fact that in the device for loading and unloading bulk materials the tank is made of two located one above the other parts, each of which has one conveyor, and both parts of the tank are mounted with the possibility of relative rotation about the vertical axis.

In addition, the upper part is connected to the lower part by means of supporting rolling elements. .

Figure 1 shows the structure of a device for loading and unloading bulk materials, a section along the axis of the tank; figure 2 - connection of the upper and lower parts of the tank.

The device for loading and unloading materials consists of a cylindrical tank 1, divided into upper 2 and lower 3 parts, with the upper part 2 mounted on the lower part 3 rotatably around a vertical axis. A screw conveyor is inserted into the side wall of the upper part 2 of the reservoir, including a flexible hose 4 and a spiral 5, the end of which is fixed on the axle

bodies 6, installed on the opposite side of the upper part 2 outside it. A second screw conveyor is inserted into the side wall of the bottom 3,

5 in. A flexible flexible rod 7 and a spiral 8, the end of which is fixed on the axis of the engine 9 mounted on the opposite side of the lower part 3. Parts 2 and 3 of the cylindrical reservoir 10 1 are rotatably connected to one another.

To facilitate rotation of the upper part 2 of the cylindrical tank 1 relative to its lower part 3 on

 5 of their connected ends are fixed flanges 10 and 11, between which the support bearing 12 is installed.

Spirals 5 and 8 screw conveyors can be made of wire,

20 from a narrow ribbon, or even in the form of a continuous ribbon. Swords 4 and 7, in accordance with the flexibility of the spirals 5 and 8, are also made flexible, but can be rigid. In addition, in the proposed device any known constructions of conveyors can be used — belt, vibration, etc., or combinations thereof. So as the top conveyor belt can serve

30 conveyor, and as the lower - inclined chute, which can be made flexible or telescopically sliding.

The unloading, for example, of a railroad car and the loading, for example, of a material vehicle with the aid of the device proposed, is carried out as follows.

A tank consisting of the upper 2 and lower 3 parts is installed at the hatch or open doors of the car. The intake end of the upper screw conveyor, including the flexible hose 4 and helix 5, is immersed in the material in the car. The output end of the lower conveyor, including a flexible hose 7 and a spiral 8, is placed in the back of the car. Engines 6 and 9 are turned on and the material is transferred from the car to the car body. As the material is withdrawn from the center of the car, the intake end of the upper screw conveyor moves one end of the car, bending the flexible hose 4 and the spiral 5. If the flexibility of the upper screw conveyor is limited and does not allow it, turn the upper part 2 of the tank to the side where it should be pick up the material Bend the hose 7 and the spiral 8, extract the end of the lower conveyor in the car body, evenly distribute the material on the body.

The proposed device with the same length of conveyors and with the same flexibility allows to take bulk material from a larger area, without moving the device itself or the vehicle, this reduces the requirements for flexibility of conveyors

which simplifies their design and manufacturing technology. In addition, it allows reducing the required curvature of conveyors, the proposed device reduces energy costs for transporting bulk material in the process of loading and unloading operations, since reducing the curvature of the material movement path decreases not only the overall path length, but also the energy cost per unit path. .
