The drying tank is provided with a safety valve port, a vacuum interface, a temperature sensor interface, a pressure sensor interface, a humidity sensor interface, a wet dehumidification interface, a gas exchange valve interface, a steam interface, a water outlet, etc., respectively, through a pipe or directly connected to the vacuum pump, the sensor , diaphragm pump, steam generator, valve, etc., there is an electric heating tube, fan inside, and an asbestos insulation layer on the outside. The drying tank is the main working place for drying and heat treatment of wood. Because vacuum drying and high temperature and high pressure heat treatment are required, the drying tank is resistant to high pressure, high temperature, and vacuum, and the sealing requirements are also high.
The dry tank is in the form of a cylindrical tank that is vacuum-resistant against the external atmospheric pressure and is horizontally installed. In order to ensure the pressure bearing capacity of the dry tank, the tank body is lightly rolled and welded with a certain thickness of steel plate, and each of the two ends has a continuous radius of curvature, and the stress distribution is relatively uniform.
The elliptical head is sealed. The head is designed as a switchable door, the door is fixed on the tank door bracket, and the bracket and the tank flange are connected by a left and right pin. The screw nut mechanism of the tank door head is used for locking the tank body and the tank door. A double-layer heat-resistant rubber ring is used as a gasket between the tank flange and the tank door flange. In order to solve the problem that the inner space of the tank can not be installed, the fan is installed in the tank body, and the outer belt is connected with the pulley. The pulley shaft is connected with the fan through the sleeve connected with the head, and the sleeve is equipped with a contact type. Mechanical sealing mechanism.
