Structure description:
1, the furnace body is a vertical shell, using double water sandwich structure, the upper and lower flanges are welded into a cylindrical structure. The inner and outer walls are stainless steel (304) sandblasting treatment, and the flange plane is provided with a sealing groove. The "O" ring vacuum seal, in order to prevent the "O" ring aging due to high temperature, are equipped with water cooling device, the side of the furnace body is provided with suction holes, electrode extraction holes, observation holes, temperature measuring holes, etc.
2, heating element: the use of energy-saving tungsten mesh structure, it is connected with the electrode, and by the furnace control system three-phase power supply after transformer step-down with bronze connected to three leading electrodes, forming a control loop, less power consumption, novel structure.
3, heat insulation screen: the heat insulation screen around the furnace, the top and the bottom are made of two layers of tungsten sheet, eight layers of molybdenum sheet and a layer of 304 stainless steel bracket, which are processed into an overall heat insulation system.
4, the furnace cover: the double-layer water sandwich structure, the inner and outer walls are stainless steel sandblasting treatment, welded with the flange, the center of the furnace cover is equipped with temperature control hole.
5, the furnace frame box: by the section steel and steel plate group welded into a box-type frame structure, the furnace body is placed on the furnace frame.
6, water cooling system: by a variety of valves, pipelines and other related devices, with water, sound and light alarm and automatic cut off the heating power supply function.
7. Vacuum system: Using a TRP-60 direct connection mechanical pump (advantages of small pollution vibration) no oil, novel structure, a molecular pump, vacuum unit, vacuum filter, air discharge valve (manual and pneumatic), pneumatic high vacuum flapper valve, pneumatic disc valve, vacuum pressure gauge (±Pa), vacuum pipe and pump using metal corrugated hose, quick joint connection, The vacuum measuring instrument is a composite digital high vacuum measuring instrument, which has a wide measuring range and can realize the whole process of continuous vacuum measurement.
8, control system: with multiple groups of P.I.D function automatic control, with over temperature sound and light alarm function, electric control system also has over current, water, over temperature sound and light alarm function. The main electrical components are Omron or Schneider brand, the electrical control system is concentrated in the control cabinet, and the panel is designed with a 10-inch LCD touch screen, current and voltmeter, vacuum gauge, etc. The control cabinet is a standard electric control cabinet structure with integrated ventilation system. It can ensure that the normal use of components and instruments in the cabinet will not be affected because the ambient temperature is too high.
All operating conditions are equipped with safety interlock protection, with overtemperature power off, water power off (stop heating, vacuum pump, etc.). Set up the necessary sound and light alarm and protection, such as overtemperature, low water pressure, low air pressure, set up an emergency switch.
