Drying device heat conducting oil compensator

Abstract

The invention relates to a heat conducting oil compensator of a drying device, which belongs to the heating equipment field. The heat conducting oil compensator of a drying device, arranged on cooling fins, comprises an oil storage chamber communicated with the cooling fins through an expansion tube and an oil-gas separator communicated with the cooling fins through an exhaust pipe, wherein, the lower part of the oil-gas separator is provided with an oil outlet pipe communicated with the oil storage chamber; an oil-receiver communicated with the oil storage chamber is arranged on the upper part of the oil storage chamber, and an oil tank is arranged in the oil-receiver; the upper part of the oil-gas separator is provided with a gas transmission pipe, which is communicated with the oil tank passing through the shell wall of the oil-receiver. Through the arrangement of the exhaust pipe, the expansion pipe and the oil tank, an exhaust outlet is not exposed to air for being sealed to lower the carbonation velocity of the heat conducting oil and increase the using life of the heat conducting oil; the exhaust outlet sealed with cold oil cools gas exhausted to make the temperature of the gas exhausted lower than flash temperature, so that danger is not easy to happen.

Description

technical field [0001] The invention relates to a heat conduction oil compensator of a drying device, belonging to the field of heating equipment. Background technique [0002] Hawthorn or other food processing requires a drying device. The drying device is equipped with a heat transfer oil system. The compensator used in the traditional heat transfer oil system, the expansion pipe and the exhaust pipe are the same pipe, so that the heat transfer oil can directly contact the air. The carbonization speed of the heat transfer oil is accelerated, which reduces the service life of the heat transfer oil, and the heat transfer oil in the compensator may reach the flash point temperature during operation, and the gas discharged from the exhaust pipe directly contacts the atmosphere and has a high temperature, which is likely to cause safety accidents . Contents of the invention [0003] The technical problem to be solved by the invention is to provide a safe and environment-frie...
