Novel sealing mechanism for shaft end of mixing machine

Abstract

The invention relates to a mixing machine, in particular to a novel sealing mechanism for a shaft end of the mixing machine. The novel sealing mechanism for the shaft end of the mixing machine comprises a sealing seat (4) and a sealing cover (1), wherein the sealing seat (4) and the sealing cover (1) are installed on a main shaft (5) in a sleeved mode. The novel sealing mechanism further comprises an abrasion-resistant sleeve (6), a first oil seal (7), a space ring (8) and a second oil seal (10). The sealing cover (1) is connected on the end face of one side of the sealing seat (4). A through hole (4-1) is formed in the sealing seat (4), an air inlet connector (3) is arranged at the position of the through hole (4-1), the sealing cover (1), the first oil seal (7) and the second oil seal (10) are installed on the outer diameter of the abrasion-resistant sleeve (6) in a sleeved mode, the outer diameters of the first oil seal (7) and the second oil seal (10) are installed in a hollow cavity on the front portion of the sealing seat (4) in a clamping mode, and the space ring (8) is installed between the first oil seal (7) and the second oil seal (10). The novel sealing mechanism is provided with multiple and various seals, the phenomenon of material leakage or powder injection does not occur, a sealing effect is good, and sealing is safe and reliable.

Description

technical field [0001] The invention relates to a mixer, in particular to a novel mixer shaft end sealing mechanism. The invention belongs to the technical field of manufacturing and processing of mixing mechanical equipment. Background technique [0002] The mixer is a common mixing equipment that is widely used to stir and mix materials evenly. It is mainly used in feed, grain, medicine, chemical industry and other fields. The mixer generally drives the main shaft of the mixer to rotate through power, and the rotation of the main shaft drives the paddles or stirring rods on the main shaft to rotate synchronously, so that the paddles or stirring rods can stir and mix the materials. effect. In the mixer, the shaft end of the main shaft is set on the wallboard of the mixer, and the shaft end of the main shaft is sealed by the shaft end sealing mechanism of the mixer to ensure that the material will not escape from the shaft end of the main shaft during the mixing process o...

AI Technical Summary

Problems solved by technology

The existing mixer shaft end sealing mechanism still has the following defects: mechanical seal is used, the sealing effect is poor, material leakage or powder spraying occurs at the shaft end of the main shaft, especially during the premix mixing process It is more serious, which not only affects the mixing effect, but also pollutes the working environment, and even brings certain safety hazards
