Description

one

This invention relates to industrial transport, in particular to bucket elevators.

Elevators are known, including a casing with nozzles, drive and tension drums, which bend around a flexible cable body with cargo carriers, with their elements, which bends at the place of loading and unloading.

The disadvantage of these elevators is a large spillage of the transported material, which reduces the productivity of the elevator.

Bucket elevators are also known, which have a casing with loading and unloading nozzles, drive and tension drums, bending around a flexible traction tape, on which buckets are fixed, having elastic elements for protection against spilling, fixed at one end on the bottom of the previous bucket, and the other on the inside. parts of the rear bucket wall

The disadvantage of these elevators is a large spillage and, as a result, low productivity of the elevator.

The aim of the invention is to ensure uniform loading and unloading and increase reliability of operation.

For this, the proposed elevator is equipped with deflecting rollers mounted on the casing at the places of tape bending and interacting with the edges of the tape, which is made wider than the width of the bucket by the length of the rollers, while the elastic elements are installed at one end on the outer side of the side wall of the previous bucket and the other on the inside of the side wall of the subsequent bucket.

FIG. 1 shows the proposed elevator; in fig. 2 - the same, option with intermediate loading; in fig. 3 - part of the working body of the elevator; in fig.

4 is a view along arrow A in FIG. 3; in fig.

5 - inclined section of the working body; in fig. 6 is a view along arrow B in FIG. five.

The elevator contains a working body in the form of a traction belt 1 with buckets 2 fixed on it, drive 3 and tension 4 stations, casing 5 with unloading pipe 6 (see Fig. 1).

The bucket 2 is loaded with material through the nozzle 7 in the lower ascending part of the traction belt 1, which is made with a bend, forming an inclined section 8. The angle of inclination of section 8 is chosen so that when the bucket 2 is loaded, the front wall of the bucket 9 takes a vertical position.

For better unloading, the bend 10 is made in the upper part of the downstream traction strip 1, similar to the bend at the loading point. On the bends of the traction belt 1, the bypass rollers I are mounted, therefore the width of the traction belt 1 exceeds the width of the bucket 2 by the amount needed to install the rollers 11 (see Fig. 6). To ensure reliable passage of the bend sections, the back wall 12 of the bucket 2 has a curvature equal to the bend radius of the pull tape 1 on the bypass rollers 11. The elevator design allows for drying, intermediate loading, for which the pull tape 1 has an additional bend 13 along the height of the rising branch . In order to eliminate blocking by the material between the back wall 12 of the bucket 2 and the traction belt 1, the front wall of each bucket is connected by a rubber plate 14 to the rear wall 12 of the next one, its bucket 2. The rubber plate 14 is installed with a slack, which is selected during the bypass drive 3 and tension Zhnuyu 4 stations. To eliminate spills when loading, buckets 2 are fixed on traction belt 1 so that each bucket 2 enters the next one, and side walls 15 are interconnected by elastic elements 16, for example corrugated rubber plates mounted at one end on the outside side of the previous bucket and the other on the inner wall of the side wall of the subsequent bucket. The buckets 2 are loaded in the lower part of the elevator on the inclined section 8 through the pipe 7. The main part of the material immediately pours into the bucket 2, and the rest falls on the front wall 9 of the previous bucket and, along its rubber plate 14, enters the bucket 2. The elastic elements 16, which connect the side walls 15 of the buckets, prevent the material from spilling in the direction perpendicular to the movement of the working member 2. The buckets 2 with the material freely pass the bend section, since the curvature of the rear wall 12 has a curvature equal to p to the bend of the traction belt 1 on the bypass rollers 11. At the top of the elevator at bend 10 (similar to the inclined loading section 8), the material is poured out from the buckets 2 and removed by the discharge nipple 6. If necessary, the intermediate loading is also fed by the loading nozzle 7 to the additional bend 13 along the height of the ascending branch. Palichi in the working body of the elevator at the loading point of the inclined section (with a certain angle of inclination) increases the reliability of the elevator due to the absence of jamming of the working body in the lower part of the elevator. Additional installation of rubber elements between buckets and the arrangement of buckets with overlap eliminates material spillage when loading, which increases the reliability of the elevator. Installing a rubber element between the front wall of each bucket and the back wall of the next one increases the durability of the traction tape, as it closes the material in the gap between the bucket and the tape. The elevator design allows intermediate loading, which is often necessary under production conditions. Claims of the invention: An elevator comprising a casing with loading and unloading nozzles, driving and tension drums, enveloped by a flexible traction tape on which buckets are fastened, having elastic elements for protection against spillage, in order to ensure uniform loading and unloading and increase the reliability of operation, it is equipped with deflecting rollers mounted on the casing at the places of bending of the tape and interacting with the edges of the tape, which is made wider than the width of the bucket by the length of the rollers; The elastic elements are mounted at one end on the outside of the side wall of the previous bucket, and the other on the inside of the side wall of the subsequent bucket.
