Problems solved by technology
There are two disadvantages of this sealing structure: first, the moving ring 2A is in direct contact with the moving ring seat 7A, and there is no floating at all. The moving ring 2A is connected to the moving ring seat 7A by means of the limit sleeve 6A and screws. The end face of the sealed friction pair frequently leaks; secondly, because the sealing structure of the sealing ring 4A is too cumbersome, the sealing position is prone to leakage, which affects the service life of the sealing device

The invention discloses a mechanical sealing device for a vertical ball mill. The mechanical sealing device comprises a static ring component, a movable ring, an anti-rotation pin, a limiting sleeve,a movable ring seat and a shaft sleeve, wherein the static ring component is connected with one end of the movable ring, the other end of the movable ring is connected with one end of the anti-rotation pin, the other end of the anti-rotation pin is connected with one end of the movable ring seat, the other end of the movable ring seat is connected with the limiting sleeve, the limiting sleeve is arranged on the shaft sleeve, and the movable ring seat is arranged on the shaft sleeve; a first gap is formed between the bottom of the movable ring and the shaft sleeve, a second gap is formed between the other end of the movable ring and the movable ring seat, and the anti-rotation pin penetrates through the second gap to connect the movable ring seat and the movable ring. The invention furtherprovides a sealing method of the mechanical sealing device for the vertical ball mill. According to the sealing device and the sealing method, the problem that a the sealing end surface is leaked dueto end surface deformation caused by direct contact is solved, the sealing performance is improved, and the service life of the sealing device is prolonged.
Description
technical field [0001] The invention relates to the field of mechanical sealing devices, in particular to a mechanical sealing device and method for a vertical ball ink machine. Background technique [0002] The primary seal in the original mechanical seal device of the imported vertical ball ink machine, such as figure 1 and figure 2 As shown, it consists of a static ring assembly 1A, a moving ring 2A, a sealing ring 4A, a limit sleeve 6A and a moving ring seat 7A. The end face of the static ring assembly 1A is connected to one end of the moving ring 2A, the other end of the static ring 2A is connected to the moving ring seat 7A, the lower end of the moving ring seat 7A is provided with a sealing ring 4A, and the moving ring seat 7A is connected to the limit sleeve 6A. It plays a decisive role in the long-term operation of the seal. There are two disadvantages of this sealing structure: first, the moving ring 2A is in direct contact with the moving ring seat 7A, and the...
