Cooling jacket for mica sintering equipment

Abstract

The invention provides a cooling jacket for mica sintering equipment and belongs to the technical field of mica sintering. The cooling jacket for mica sintering equipment comprises an inner sleeve provided with sealing plates at two ends and an outer sleeve; the outer sleeve is provided with a water inlet pipe and a water outlet pipe; and the water inlet pipe and the water outlet pipe are respectively positioned at two ends of the outer sleeve; an overflow barrel is arranged between the inner sleeve and the outer sleeve; one end of the overflow barrel is hermetically connected with the sealing plate close to the water inlet pipe; an overflow port is formed between the other end of the overflow barrel and the sealing plate close to the water outlet pipe; the overflow barrel divides the area between the inner sleeve and the outer sleeve into a first heat exchange area and a second heat exchange area; after penetrating through the overflow barrel, the water inlet pipe is communicated with the first heat exchange area; the water outlet pipe is communicated with the second heat exchange area. The cooling jacket for the mica sintering equipment is suitable for cooling of a high temperature mica plate and is good in cooling effect.

Description

technical field [0001] The invention belongs to the technical field of mica calcining, and relates to a cooling jacket for mica calcining equipment. Background technique [0002] Usually, mica is calcined at high temperature to evaporate the crystallization water in the mica sandwich, so that the mica sheets expand between layers, so that the mica sheets are easy to peel off. In the process of calcining mica flakes with calcining equipment, mica flakes need to be heated to 920-950°C to evaporate the water of crystallization. Usually, the calcined mica flakes are directly sucked into the cooling tower by negative pressure and cooled by spray water, and the spray water often has residual temperature after cooling, but these waters are polluted by mica flakes, contain particles, and have a darker color. It can only be discharged as waste water, resulting in a waste of resources. [0003] After continuous exploration, people try to initially cool the calcined mica sheet with a...

Usually, the calcined mica flakes are directly sucked into the cooling tower by negative pressure and cooled by spray water, and the spray water often has residual temperature after cooling, but these waters are polluted by mica flakes, contain particles, and have a darker color. Can only be discharged as waste water, resulting in waste of resources

[0003] After continuous exploration, people try to initially cool the calcined mica sheet with a heat exchanger, and then use spray water to cool it. However, when the existing heat exchanger is directly used for cooling the mica sheet, due to the direct connection with 920- 950°C mica sheet cooling, there are disadvantages such as cooling water will quickly evaporate into steam, cooling water becomes steam and cannot be collected, and cooling efficiency is low
