Abstract

This invention relates to a lifting and transport machinery. The goal is to reduce energy consumption and to prevent the fragmentation of the transported material, as well as to increase the lifting height at constant energy consumption. For this, the cylindrical body (K) 1 of the conveyor with the rotating screw 8 placed in it with the shaft 9 is made of the fixed lower part 3 and the upper part 4 rotating in the same direction with the screw 8 from the drive 5. Above the upper part 4 K 1 is assembled box

Description

one

The invention relates to a lifting machinery industry, in particular to screw conveyors, and can be used to transport bulk materials such as flour, shreds, talcum, grains, etc. in various industries.

The purpose of the invention is to reduce the specific energy consumption and to prevent crushing of the material, as well as to increase the lifting height at constant energy consumption.

The drawing schematically shows a vertical screw conveyor, a general view.

The vertical screw conveyor consists of a body 1 mounted on the base 2. The body 1 is made of two parts — the bottom 3 is fixed and the top 4 is mounted rotatably from the actuator 5. The top part 4 of the body rotates in a hinge 6 and bearings 7. Inside the top and the lower parts of the housing 1 is placed a screw 8 with a vap 9 rotating from the actuator 10 in the bearing 11, wherein the direction of rotation of the upper part 4 of the housing and the screw 8 coincide. Above the upper part 4 of the housing is placed a fixed box 12 with a planet carrier 13 mounted on the shaft 9.

In the lower part 3 of the housing 1 there is a loading nozzle 14, and in the collecting box 12 there is a discharge nozzle 15.

Drive 10 screw 8 bring in

rotation, and the drive 5 is driven in rotation the upper part 4 of the housing I

and rotates in bearings 7 and bushing 6.

The loading nozzle 14 is conveyed by the conveyed piece, which first enters the lower part 3 of the housing 1, and then into the upper rotating part 4.

Under the action of rotation of the screw 8 and the upper part 4 of the housing 1, the transport material acquires a rotational-translational motion and is pressed against the surface of the cylindrical body I by the resulting centrifugal force. When the screw 8 is rotated in the same direction as the body, but with a greater angular velocity, the product moves along the helix. At the same time, the product (material) does not spill at the installation sites of the intermediate supports or into the gap between the screw 8 and the housing 1, the material remaining in the gap after passing the next turn of the screw is held by centrifugal force. Having reached the upper end of the housing 1, the material is dumped into the fixed team box 12, from which the carrier 13 is fed into the discharge pipe 15.

In case a uniform spreading of the transported material around the circumference is necessary, the assembled box 12 and the carrier 13 are not installed.

When the upper part 4 of the conveyor housing 1 is rotated together with the screw 8 for all particles of material, regardless of their location, the centrifugal force acts. It is created by the screw 8 itself, as well as by the rotating part 4 of the housing 1.
