Passive cleaning device for cylindrical mixer

Abstract

This utility model relates to the technical field of mixing equipment for sintering processes in the metallurgical industry. It discloses a passive cleaning device for a cylindrical mixer, comprising a base, a support frame, and a mixer. This utility model, by setting up a base, support frame, mixer, auxiliary wheel, mounting frame, transmission device, and cleaning mechanism, first opens the cleaning mechanism, causing the drive motor to rotate. The drive motor drives the cleaning cylinder to rotate, which in turn drives the toothed gears to rotate. Then, the transmission device is opened, and the servo motor starts to rotate. The servo motor drives the driven wheel to rotate, and the driven wheel, through a threaded connection, drives the lead screw to move. The lead screw drives the mounting groove to move, and the mounting groove drives the toothed gears to move, thus cleaning the mixer. This solves the problem in the prior art where the inner wall of the mixer needs to be cleaned manually, which is prone to material collapse during manual cleaning, potentially causing injury to workers.

Description

Technical Field

[0001] This utility model belongs to the technical field of mixing equipment for sintering processes in the metallurgical industry, and particularly relates to a passive material cleaning device for a cylindrical mixer. Background Technology

[0002] In the metallurgical industry, sintering is an important method for transforming fine powder materials into lumpy materials. It is mainly used to prepare raw materials for blast furnaces. The sintering process can improve the density, strength and permeability of materials, creating favorable conditions for blast furnace smelting. The mixing equipment plays a crucial role in the sintering process, ensuring the uniform distribution of various components in the raw materials, thereby affecting the quality of the sintered ore.

[0003] Generally, materials are mixed by rotating a cylinder. The materials move axially inside the cylinder and are mixed under the action of friction and centrifugal force between the inner and outer walls of the cylinder. The cylinder mixer is suitable for mixing powdery and fine granular materials. The problem with the above technology is that in the existing technology, the inner wall of the mixer needs to be cleaned, which is generally done manually. During the manual cleaning process, the inner wall of the mixer is prone to material collapse, which can easily cause injury to the workers. Utility Model Content
