This equipment consists of a rotary heating furnace (with an electric flip device), furnace tubes, electrical control, vacuum system, etc.
1. The rotary heating furnace is composed of a furnace shell, furnace lining, heating element, and furnace tube rotating device. The furnace shell is divided into upper and lower parts, and the upper part is electrically controlled. It can be flipped and opened when loading and unloading the furnace tubes. The furnace lining adopts alumina fiber lining. The heating element is installed on the furnace lining using high-temperature silicon carbon rods. The furnace tube rotation device adopts frequency conversion speed control drive, and the rotation speed can be arbitrarily set within a certain range.
2. The furnace tube is a circular stainless steel variable diameter tube, which adopts a structure with thin ends and thick middle to ensure sufficient reaction of the material in the middle heating part. The pouring of the product can be electrically controlled by tilting angle. The furnace tube can rotate clockwise or counterclockwise, and the rotation speed can be adjusted within a certain range. Users can determine the appropriate rotation speed based on the shape, material, and temperature of the processed product under high temperature conditions. The furnace tube material is SUS310S stainless steel, and there is a lifting plate inside the tube, which can lift the material during the rotation process and receive heat evenly. Sealing flanges are used at both ends of the furnace tube, and a rotating joint is installed at the inlet end to allow for air circulation. Materials enter and exit from the inlet end.
3. Temperature control system: This furnace is equipped with an automatic temperature control system and PID automatic power regulation control, which can automatically adjust the input of current. The temperature control instrument adopts a programmable intelligent instrument, which can set the heating curve in sections. The control execution system adopts thyristor control and is equipped with air switches and fast fuses for secondary protection, with overload, short circuit and other protective measures. It is also equipped with air switches and fast fuses for secondary protection, with overload, short circuit and other protective measures to reliably ensure the normal operation of the control components.
4. Safety measures: Equipped with an over temperature alarm device. The electric heating element is equipped with an ammeter, a voltmeter, and power on interlocking protection and safety grounding measures to ensure safe use.
5. Vacuum system: Adopting magnetic fluid sealing to ensure normal vacuum pumping during furnace tube rotation. The vacuum pump adopts a rotary vane pump with a pumping speed of 8L/S. By turning on the vacuum pump switch, vacuum can be pumped.
6. Flowmeter: The mass flow meter accurately controls the flow rate and can pass through inert gases such as nitrogen.
