The invention discloses a mechanical seal protection device for a bead mill. A sealed sealing liquid container is arranged on the outer portion of a mechanical seal and is connected with a sealing liquid flow channel in the mechanical seal through a circulating pipe, the circulating pipe is provided with a circulating pump, and the sealed sealing liquid container is provided with a heat exchange structure. Under the effect of the circulating pump, sealing liquid in the mechanical seal takes out heat in the mechanical seal, enters the sealing liquid container and is cooled through the heat exchange structure on the sealing liquid container, the sealing liquid cooled enters the mechanical seal again, and the effect of protecting the mechanical seal is achieved through the circulation. Besides, a liquid level warning device can be further arranged on the sealing liquid container to prevent the sealing liquid from being lower than the warning line; a sealing liquid circulating warning device can also be arranged to give an alarm against failure in sealing liquid circulation caused by circulating pump faults or other reasons; and on-site pressure and temperature can be monitored by arranging a pressure meter and a thermometer on the sealing liquid container.
Description
technical field [0001] The invention belongs to the field of bead mill structure, and in particular relates to a protection device for the mechanical seal of the bead mill. Background technique [0002] In the prior art, there is a mechanical seal between the rotating shaft and the stator of the bead mill, but during the high-speed rotation, the mechanical seal will generate heat, which accelerates the aging of the mechanical seal and easily leads to damage to the mechanical seal, increasing the The maintenance rate is reduced and the service life of the equipment is reduced. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mechanical seal protection device for bead mills. The mechanical seal protection device for bead mills of the present invention can take away the heat of the mechanical seal, and has an alarm function, which protects the mechanical seal. It has a protective effect, and has a simple structure and ...
