Description

Technical Field

[0001] The utility model relates to the field of high-temperature horizontal tank mechanical seal cooling, in particular to a high-temperature horizontal tank mechanical seal cooling device. Background Art

[0002] When the existing high-temperature horizontal tank is in use, the material needs to be introduced into the tank, and then the motor drives the stirring device so that the stirring device can stir the material in the tank. When the stirring device rotates, both ends of the stirring device will be assisted by the bearing seat for rotation, and the shaft and the body of the stirring device will be sealed by mechanical sealing to avoid gaps between the shaft and the body. There are various mechanical seal structures, and the most commonly used mechanical seal structure is the end face seal. The static ring and the dynamic ring of the end face seal form a pair of friction pairs, and the function of the friction pair is to prevent medium leakage. However, the high-temperature horizontal tank body has defects such as easy leakage, frequent maintenance and replacement, which limits industry production, high labor intensity and failure to meet hygiene requirements. At the same time, the high-temperature horizontal tank will transfer heat to the bearing seat. At this time, the temperature of the bearing seat and the mechanical seal will increase. In order to control the heat transfer and extend the overall service life, the bearing seat and the mechanical seal need to be cooled.

[0003] Therefore, it is necessary to invent a mechanical sealing cooling device suitable for high-temperature horizontal tanks. Utility Model Content
