The specific embodiment
Shown in accompanying drawing, the present invention about installment work platform 8 on two steelframes 1, workbench upper mounting rail 7; The heating furnace 4 bottom surface slide block 7a of hollow are installed on the guide rail 7, and heating furnace 4 can move back and forth about doing on the guide rail 7, and the bracing frame of boiler tube 2 is equipped with at the two ends of workbench 8 respectively; Be provided with respectively in the identical boiler tube 2 of two structures can dismounting reaction tube 3; The outside port of export of two boiler tubes 2 is all installed the sealing flange 2a that has rubber seal, outside the boiler tube 2 near sealed end, is welded with water-cooling jacket 2b, in the workbench 8 vacuum pipe is housed; The two ends of vacuum pipe are communicated with separately boiler tube 2 through valve respectively; All be connected to pressure vacuum gauge 5c on two boiler tubes 2, vacuum pipe meets atmosphere control system 5, temperature control system 6 be contained in heating furnace 4 interior thermocouple 6a and be connected.
It is 50mm that steelframe 1 adopts width, and thickness is that the channel-section steel of 5mm is welded; Boiler tube 2 is the pipe of 304 steel matter, has good pyro-oxidation resistance.Boiler tube 2 one ends weld with end socket, another termination sealing flange 2a.Outside pipe, be welded with water-cooling jacket 2b, a water inlet and a delivery port are arranged, in building-up process, pass to cooling water all the time in order to the protection sealing ring near sealing ring.Heating furnace 4 adopts nichrome resistance wire 4a heating, and resistance wire 4a evenly closely is wrapped on the spiral high aluminum pipe.Fill refractory thermal insulating material 4b such as refractory brick, alumina silicate refractory slab and heat-preservation cotton in the middle of the body of heater, make body of heater have good heat insulation effect; Reaction tube 3 is made by the seamless steel pipe of 304 trades mark, and the two ends seal cap can reduce in the building-up process steam inwall that is deposited on boiler tube 2 of overflowing and cause significant loss and proportioning deviation.Disposed the reaction tube of several kinds of different length specifications, can select according to actual needs; Atmosphere control system partly is made up of vavuum pump 5a, protective gas interface 5b and pressure vacuum gauge 5c etc., can vacuumize or fill protective atmosphere according to synthetic actual needs, by pressure vacuum gauge 5c indication vacuum or pressure state.If synthetic the need carried out under vacuum state, then reaction tube is vacuumized with 2XZ-1 type rotary-vane vaccum pump 5a.If synthetic the need carried out in protective atmosphere, then charge into required protective gas from meeting gas port 5b, common like hydrogen, argon gas, nitrogen etc.; Temperature control system 6 mainly is made up of thermocouple 6a, temperature controller 6b and controllable silicon 6c.Thermocouple 6a inserts the position of body of heater 4 centers near boiler tube 2, and this point for measuring temperature has reflected the mean temperature in most of zone in the stove preferably.The type of thermocouple 6a can require to select according to different temperature, generally selects the thermocouple of nickel chromium triangle-nisiloy for use.AI-708A type intelligent temperature controller 6b is according to the actual needs design temperature parameter of building-up process, and common accurate mensuration and the control of accomplishing temperature conditions that combines with thermocouple 6a, controllable silicon 6c generally can be controlled at temperature in 5 ℃ the scope; Body of heater 4 can be on guide rail 7 move left and right.When the boiler tube of a side is in running order, can accomplishes the charging of another boiler tube simultaneously and vacuumize or fill steps such as protective gas.After treating the synthetic completion of a side, only need body of heater 4 is pushed into opposite side and can proceeds to synthesize along leading 7 rails, realized the accurate serialization of process.Behind end of synthesis, powered-down and water source, boiler tube cool off naturally, take out to obtain product.
