Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of internal mixers, in particular to a self-lubricating oil-saving structure for the end face seal of an internal mixer. Background Technique
[0002] On internal mixer equipment, the end face seal plays a sealing role for the internal rubber compound and dust under relative rotation. The friction mode between the dynamic ring and the static ring of this end face seal is direct contact rotary sliding friction. Generally, lubricating oil needs to be added for sliding friction, and the pressurized lubricating oil is directly introduced into the friction surface to play a lubricating role. However, in a high-pressure and high-speed rotation environment, it is difficult to maintain the liquid film between the friction surfaces, and the oil film is often damaged by the frictional heat generated by high pressure and high rotation speed. Only boundary lubrication and semi-liquid lubrication can be formed on the friction interface, which increases the loss of friction parts, reduces the service life, consumes a large amount of lubricating oil, wastes resources, and has a high application cost. In addition, during the use of the internal mixer, oil and sewage are continuously discharged from this position, and this oil contains pollutants, which requires a certain cost for cleaning treatment.
[0003] Therefore, there is an urgent need for a self-lubricating oil-saving structure for the end face seal of an internal mixer to solve the above problems. Summary of the Utility Model

[0018] The end face seal structure includes: a moving ring 1, a fixed ring 2 and a tightening oil cylinder 3. The moving ring 1 is fixedly sleeved on the outer side wall of the rotor 4. The outer side wall of the fixed ring 2 is fixedly installed with the inner side wall of the side bracket 6, and the inner side wall of the fixed ring 2 is rotatably installed with the outer side wall of the moving ring 1. The fixed end of the tightening oil cylinder 3 is installed on the outer side wall of the mixing chamber 5, and the moving end of the tightening oil cylinder 3 is in close contact with the outer side wall of the fixed ring 2. The tightening oil cylinder 3 is used to fix the fixed ring 2.
[0019] By fixedly sleeving the moving ring 1 on the outer side wall of the rotor 4, fixedly installing the fixed ring 2 with the side bracket 6, and rotatably installing the moving ring 1 and the fixed ring 2 at the same time, the moving ring 1 and the fixed ring 2 seal the gap between the rotor 4 and the side bracket 6.
[0020] In this embodiment, a rotating groove is provided on the outer wall of the moving ring 1, and a rotating block matching the rotating groove on the moving ring 1 is provided on the inner wall of the fixed ring 2 to limit the moving ring 1 and the fixed ring 2 to prevent their positions from shifting during rotation.
[0021] In this embodiment, a rotating block is provided on the outer wall of the moving ring 1, and a rotating groove block matching the rotating block on the moving ring 1 is provided on the inner wall of the fixed ring 2 to limit the moving ring 1 and the fixed ring 2 to prevent their positions from shifting during rotation.

When the moving coil 1 and the fixed coil 2 rub against each other, a transfer film is formed after the composite polymer rubs against the metal. The formation of the nano-transfer film reduces the friction coefficient between the moving coil 1 and the fixed coil 2, and can reduce energy consumption, reduce noise, etc., extend the service life of the device, reduce the failure rate of the equipment, and reduce the operating costs of shutdown and equipment maintenance.
