Large flow assembled grinding device for nano sand mill

Abstract

The invention relates to a large-flow split type grinding rotor device. The large-flow split type grinding rotor device comprises a rotating core, wherein one end of the rotating core is connected with a main shaft, the rotating core is driven to rotate by the main shaft, a hollow grinding rack is fixedly arranged on the other end of the rotating core, the rotating core and the grinding rack form a concentric rotating body with the same diameter, a plurality of rows of detachable grinding blocks are circumferentially installed along the circumferential wall of the rotating body, detachable spacing blocks are installed between two adjacent grinding blocks in each row, and material passing openings are formed between every two adjacent rows of grinding blocks and communicated with an inner cavity of the grinding rack. According to a grinding rotor, all of the grinding blocks and the spacing blocks are connected to the rotating body in a sleeved mode, when one grinding block is worn, only the rotor is disassembled, so as to replace the worn grinding block, so that the replacement cost is low. According to the large-flow split type grinding rotor device, the grinding blocks are completely distributed in the whole axial direction of the rotating body, and the grinding blocks are tightly pressed by pressing covers, so that the structure is firm, and the grinding effect is good.

Description

AI Technical Summary

Problems solved by technology

A traditional grinding machine generally includes a grinding cylinder with a grinding cavity formed inside and a feeding cavity connected to the grinding cavity. There is a grinding rotor driven by the main shaft in the cavity; however, some of the existing grinding rotors directly install grinding blocks on the rotor body, which is not convenient for installation on the one hand, and the grinding effect is not good on the other hand; The rotor adopts an integral ring structure. The biggest defect of this method is that when a certain grinding block needs to be replaced after wear and tear, the entire ring must be replaced, and the cost of replacement and maintenance is high. Among them, the grinding rotor on the stirring shaft is a conventional sand mill. The main core device of the machine is used for grinding, but the existing grinding rotors generally cannot discharge materials smoothly to the outside of the sand mill cavity, the grinding energy is small, the cylinder volume is small, the diameter of the grinding rotor is small, the continuous working time is short, and the material cannot be avoided. Shortcomings such as rapid temperature rise have adverse effects on production

At the same time, for large-scale industrial production, the grinding rotors of structural parts of many special materials cannot be manufactured into large diameters and large structural sizes, resulting in many times nano-grinding can only stay in the laboratory or pilot test stage, losing the meaning of industrial scale production
