Description

Technical Field

[0001] The present application relates to the field of drying equipment, and in particular to a double-cone rotary vacuum dryer. Background Art

[0002] The double cone rotary vacuum dryer is a double cone rotary tank. When the tank is in a vacuum state, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly flip up and down and inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

[0003] The Chinese utility model with application number CN202320425640.1 discloses a high-efficiency double-cone rotary vacuum dryer, including a base, the top of which is fixedly connected to two support seats, a drying tank is arranged on the top of the base, two transmission shafts are fixedly connected to the inner wall of the drying tank, the transmission shafts penetrate the drying tank and extend to the inside of the support seat, a driving motor is fixedly installed on the inner wall of the support seat on the right side, the output shaft of the driving motor is connected to the transmission shaft through a synchronous belt, a heat exchange chamber is provided inside the drying tank, and evenly distributed air inlet holes are provided on the left side of the transmission shaft. By providing a multi-way pipe, cold air can be filled into the heat exchange chamber, and the temperature of the drying tank and the material can be quickly reduced after the material is dried, which is convenient for rapid discharge and indirectly improves the drying efficiency. At the same time, by providing an auxiliary mechanism to support the drying tank, the drying tank remains stable during the discharge process to avoid shaking.

[0004] The wet material carries moisture, which results in a higher viscosity of the wet material. During the rotation of the drying tank, the wet material is prone to agglomerate into lumps. The moisture carried by the wet material inside the lumps is not easy to evaporate, resulting in the dried material being easily mixed with incompletely dried material, resulting in a poor drying effect.
