Pulverizer with replaceable blades

Abstract

The invention discloses a grinder with replaceable blades, which comprises a grinder box, a feeding hopper, a grinder main shaft, blades, a water tank, a motor, and a feed port. The end of the machine is connected to the feed port; the feed port is located on the right side of the top of the pulverizer box, and the middle part of the upper wall of the inner cavity of the pulverizer box is provided with a motor, and the lower end of the motor is connected to the main shaft of the pulverizer, on which there is a first groove, the first groove is provided with a first cooling fin; the other end of the pulverizer main shaft passes through the pulverizer casing and the bearing above the water tank to reach the inside of the water tank, and the pulverizer main shaft is provided with a plurality of blades, The blade is provided with a second groove, and a second cooling fin is arranged in the second groove; a discharge port is arranged at the bottom left side of the pulverizer box. The invention can evenly transport materials to the pulverizer box for pulverization, and can effectively reduce the heat of the pulverizer, and can also operate normally when the power is cut off, thereby improving work efficiency.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a pulverizer with replaceable blades. Background technique [0002] A pulverizer is a machine that pulverizes large-sized solid raw materials to the required size. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of the pulverizer in the form of high-speed impact. Using wind energy to form powder at one time, the traditional screening procedure is cancelled. Mainly used in mining, building materials and other industries. There are four kinds of external forces applied to the material during the crushing process: rolling, shearing, impact blowing and grinding. [0003] At present, most of the widely used pulverizers do not have the ability to cool down. When the heat of the main shaft and the blade is too high, the service life will be greatly reduced; and when too many materials are added to the pulverizer in turn...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the widely used pulverizers do not have the ability to cool down. When the heat of the main shaft and the blade is too high, the service life will be greatly reduced; and when too many materials are added to the current pulverizer in turn, the inlet and outlet of the pulverizer are easy to block, and Insufficient crushing occurs; in addition, the blades are all fixed on the rotating shaft, if damaged, they must be replaced together with the entire rotating shaft, which is a waste of labor and cost
