Solid material mixing device

Abstract

The invention provides a solid material mixing device, comprising a mixing chamber, a first feeding channel, a second feeding channel, a plurality of first baffles and a plurality of second baffles, wherein the first feeding channel and the second feeding channel are both located at the top end of the mixing chamber and are respectively arranged in parallel to the side wall of the mixing chamber in an inclination manner; two opposite sides of the inner wall of the mixing chamber are respectively provided with the plurality of first baffles and the plurality of second baffles, and the free ends of the first baffles and the free ends of the second baffles all incline towards the bottom end of the mixing chamber; the first baffles and the second baffles are arranged alternatively, a first extension face, extending along an inclination direction of each first baffle, of each first baffle is crossed with the second baffle adjacent to the first baffle, a second extension face, extending along an inclination direction of each second baffle, of each second baffle is crossed with the first baffle adjacent to the second baffle; and a gap is arranged between the free ends of every adjacent first baffle and second baffle. According to the solid material mixing device, a motion state of solid materials is changed under the action of gravity of the solid materials by the first and second baffles in the mixing chamber, and the solid materials are fully mixed without external driving forces, so that use of energy resources is reduced.

Description

technical field [0001] The invention relates to the technical field of material mixing, and more specifically relates to a solid material mixing device. Background technique [0002] In industrial production, it is often necessary to mix solid materials. In actual production, there are mainly two types of solid material mixing devices: belt mixing device and screw mixer. Among them: the belt mixing device is mainly used in the coal blending section of coking and gasification coal. Driven by an external force (such as a motor), the belt can mix the solid materials relatively evenly; the spiral mixer is also driven by an external force (such as a motor), and the rotating parts rotate at a high speed, so that the solid materials in the spiral channel are fully mixed. . [0003] At present, the existing solid material mixing devices all need moving parts, and the moving parts must be driven by an external force to realize the mixing of materials. Therefore, the existing solid...

Problems solved by technology

[0003] At present, the existing solid material mixing devices all need moving parts, and the moving parts must be driven by an external force to realize the mixing of materials. Therefore, the existing solid material mixing devices need to be driven by an external force, which increases energy (such as use of electricity)

[0004] In addition, the belt mixing device is only suitable for the mixing of normal temperature materials due to the limitation of its own materials, and cannot realize the mixing of high temperature solid materials; Or use it at room temperature, and when the material is greater than 300°C, because the rotating parts directly contact the high-temperature material, the requirements for the material of the rotating parts are very high. At present, the metal materials used in some high-temperature environments are not good enough, so the rotary mixer Also not suitable for mixing high temperature solid materials
