SU1558812A1 - Vertical screw conveyer for conveying hard-loose materials - Google Patents

Abstract

The invention relates to a lifting and transport machinery and can be used in agriculture, in the building materials industry, the chemical industry, and other branches of the national economy. The goal is to increase productivity and reduce energy consumption. The vertical screw conveyor includes a cylindrical housing / CC / 1 in which the transport screw / TV / 2 is located. In the upper part of CC 1 there is a discharge pipe 3, and in the lower part there is a receiving window 4, the width of which is 0.65 ... 0 75 of diameter TB 2. In the lower part of the screw conveyor there is a loading chamber 5 with side walls 6, the lower part of which is made in the form of a circle with a protrusion adjacent to the CC, and the top part is in the form of a rectangle. In the loading chamber 5 there is a loading device made in the form of a plate 10 with main and additional blades 11, 12. The material is fed into the loading chamber 5 and the blades 12 is thrown into the receiving window 4, then TB 2 - into the loading nozzle. 3 il.

Description

The part of which is made in the form of a circle with a protrusion adjacent to CC 1, and the upper one in the form of a rectangle. In the loading chamber 5 there is a loading device made in the form of a plate 10 with main and additional blades 11, 12. The material is fed into the loading chamber 5 and the blades 12 is thrown into the receiving window 4. Then the TV 2 is discharged into the discharge pipe. 3 il.

The invention relates to a lifting machinery industry, namely, screw conveyors for transporting bulk materials, and can be used in agriculture, in the building materials industry, the chemical industry and other sectors of the national economy.

The purpose of the invention is to increase productivity and reduce energy consumption.

FIG. 1 schematically shows a vertical screw conveyor for transporting bulk materials, a general view; in fig. 2 shows section A-A in FIG. one; Fig 3 - loading chamber, axonometrics.

The vertical screw conveyor for transporting bulk materials consists of a cylindrical casing 1 and a transport screw 2 located therein. In the upper part of the cylindrical casing 1 there is a discharge pipe 3, and in the lower part a receiving window 4 is made, the width of which is 0.65-0. , 75 diameter (Dtu) transport screw. In the lower part of the screw conveyor there is a loading chamber 5 with side walls 6 tangent to its lower part, made in the form of a circle 7 with a protrusion 8, and adjacent to the cylindrical case 1. The upper part of the loading chamber 5 is made in the form of a rectangle 9. In the loading chamber 5 contains a loading device made in the form of a plate 10 with main blades 11 placed on the upper surface of the cross and additional blades 12 placed on the lower surface of the plate 10. A transport screw 2 and plate 10 connect the with 13 drive.

The conveyor works as follows.

When feeding material into the loading chamber 5, it falls between its lower part,

i.e., a circle 7 with a protrusion 8, and additional blades 12, and the latter are ejected into the receiving window 4. Next, the material, falling into the interturn space of the transport screw 2, moves

them up and thrown into the discharge pipe 3.

Making the receiving opening of the cylindrical case i equal to 0.65-0.75 screw diameter 2 improves the uniformity of filling of the screw screw space and increases its filling ratio, which improves the performance of the screw conveyor as a whole.
