Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of conveying chute, specifically to a raw material conveying chute. BACKGROUND

[0002] Water slag as a byproduct in industrial production, its main components are calcium oxide, silicon oxide and magnesium oxide, shape similar to yellow sand, have certain granular and flowability. In industrial production, water slag is often used for further processing or storage of raw materials. In order to realize efficient conveying between the silo and the processing area, the chute is usually used for gravity conveying. However, due to the long distance between the silo and the processing equipment, the length of the chute often reaches 100-250 meters, which leads to a series of technical problems in the design of the chute.

[0003] The chute is an inclined channel, which transports mixed water slag solid-liquid material downward by gravity. However, in actual use, the long conveying distance makes the inclination angle of the chute not too large, so as to avoid occupying too much space and the structure design being limited. The reduction of the inclination angle directly affects the flow state of the water slag, leading to the following problems:

[0004] Solid-liquid separation phenomenon: when the inclination angle is small, the gravity is not enough to drive the particles and the liquid to flow synchronously, the solid particles are retained in the chute, and the liquid part flows out preferentially, resulting in serious solid-liquid separation phenomenon, affecting the conveying efficiency.

[0005] Particle deposition and blockage: in the long distance chute, due to insufficient flow rate or too large friction force of the inner wall of the chute, solid particles are easy to deposit and gradually form blockage, thereby affecting the stability of the overall conveying system.

[0006] Low conveying efficiency: the insufficient inclination angle of the chute and the solid-liquid separation problem lead to that the water slag cannot be continuously and uniformly conveyed, affecting the material supply of the subsequent processing equipment.

[0007] In the prior art, part of the chute design improves the conveying performance by increasing the inclination angle, improving the inner wall material or introducing a vibration device, but for the solid-liquid separation problem of the long distance chute, an effective solution has not been formed. Therefore, it is of important technical significance and application value to develop a chute design that can optimize the conveying performance of water slag, avoid solid-liquid separation and maintain high flowability.

This structure helps to improve the flow state, prevent local blockage, and improve the conveying efficiency.

[0014] In a preferred example, the utility model can be further configured as follows: the number of branch flow channels is 5-15 per 1 meter in length, and they are evenly distributed to ensure continuous mixing of solid particles and liquid.
