Screw conveyor used in wet material smashing process

Abstract

The invention discloses a screw conveyor used in the wet material smashing process. A first material conveying screw rod and a second material conveying screw rod are arranged in a material conveyingcylinder side by side, and a first auger and a second auger are arranged on the ring-shaped face of the first material conveying screw rod and the ring-shaped face of the second material conveying screw rod correspondingly. A feeding box is arranged on the top of the arc side face of the end, close to a motor installation seat, of the material conveying cylinder in an erected manner, and a storagebattery is connected to the end face of the end, away from the motor installation seat, of the material conveying cylinder. An external connection water conveying pipeline is fixedly arranged above the arc side face of the material conveying cylinder. The first material conveying screw rod is arranged to be of a hollow structure, and a heating pipe is arranged in the hollow structure of the firstmaterial conveying screw rod. Fertilizer wet materials in the material conveying cylinder are heated according to the temperature needed during fertilizer wet material pelletizing, the quality of fertilizer pelletizing is improved, the humidity of the fertilizer wet materials in the material conveying cylinder is controlled by controlling the external connection water conveying pipeline, the screw conveyor can be used for regulating the temperature and water in the material conveying process, and the practicability of the screw conveyor is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical conveying, in particular to a screw conveyer used in the crushing process of wet materials. Background technique [0002] Screw conveyor is a commonly used powder conveying equipment. It is widely used in various production fields because of its large conveying capacity, good sealing performance and high efficiency. Its principle is to use the motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can be transported horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. [0003] The mechanization of agricultural production requires fertilizers to be granulated and spherical to increase the speed of fertilization and reduce the cost of agricultural production. The fineness of the raw materials for the produc...

Problems solved by technology

[0004] 1. The existing screw conveyor does not filter and pulverize the conveyed wet material in the process of conveying the wet material. With the extension of the running time, the large wet material is easily agglomerated by the extrusion and friction of the auger Agglomeration can easily cause the feeding screw to be stuck, or even the shaft of the feeding screw to be twisted off;

[0005] 2. Most of the existing screw conveyors do not have a temperature control device for the wet material for making fertilizers, but the heating device for the screw conveyor is heated by setting a heating collar on the outer wall of the feeding cylinder, not only It causes a large waste of heat source, and at the same time causes the raw materials in the cylinder to be heated slowly and unevenly;

[0006] 3. The existing screw conveyor does not have a moisture adjustment device for the wet material used for fertilizer production, which is not conducive to controlling the temperature and moisture required for wet material granulation, and has great limitations. At the same time, the existing screw conveyor is It is difficult to clean the cylinder wall after feeding, and it needs to be disassembled for cleaning, which is time-consuming and laborious
