Detailed description of the invention
This vertical vacuum debinding furnace of the present invention, including program robot control system(RCS), air cooling system, degreasing system,
Heating electrical system, air-charging and air-discharging system, water-cooling system and peripheral auxiliary equipment, furnace shell is provided with two doors altogether,
I.e. furnace shell upper cover 2 and furnace shell lower cover 11, be shown in Fig. 1, it is characterised in that installs vacuum system in vertical vacuum furnace furnace shell
System, vacuum line communicates with heating chamber 7 pipeline, sets up vapor tight tank 6 in heating chamber 7, heating chamber 7 and wherein
Vapor tight tank 6 be equipped with upper and lower opening, furnace shell upper cover 2 suitable for reading is charging and discharging mouth, furnace shell upper cover 2
Air door 3, the upper screen body 4 of heating chamber and the top cover 5 of vapor tight tank 6 driven by cylinder 1 is fixed successively inside stove.
The top cover 5 of hermetically sealed can and upper screen body 4 all have passage, vapor tight tank 6 bottom to have opening, can be by following structure
Realize airtight: be directly protruding in heating chamber and vapor tight tank 6 UNICOM by four adapters bottom heating chamber 7, end opening
In furnace bottom furnace shell lower cover 11, by air intake assembly 10 make four adapter through heating rooms 7 lower screen body 9,
Enter in airtight tank body 6, see Fig. 2.It is de-that air intake assembly 10 other end connects evacuation respectively through triplate line 17
Fat pipeline, air-cooled pipeline, such structure can reduce thermal loss on the premise of ensureing bigger ventilation,
Cooling gas also can be made to be evenly distributed.This triplate line 17 is provided with heater, can be to pipeline heating.
Also being fixed with multiple siege column in the framework of lower screen body 9, siege column penetrates lower screen body 9 and enters vapor tight tank
Bottom 6, holding up charging tray and support processing workpiece, vapor tight tank 6 makes processing workpiece be isolated with heating chamber 7；Heating
Heater 8 is installed, to the overall heating of vapor tight tank 6 between room 7 and vapor tight tank 6.Shielding body 9 under heating chamber is
Air-cooled air inlet position, is also the end of vapor tight tank 6.The air door 3 driven by cylinder 1 realizes opening of vapor tight tank 6
Opening with airtight, when evacuation and degumming, air door is closed and is made vapor tight tank become hermetic container, stops the diffusion of glue steam, and
Realize sharing in the evacuation of furnace interior, air-cooled, defat with triplate line 17.
Upper screen body 4 and top cover 5 are structure as a whole: top cover 5 is circular metal flat board, disc are distributed multiple etc.
Hole, footpath, and burn-on pipe at passage surrounding vertical, pipe is inserted in the passage of upper screen body 4 and be arranged as one.
Seeing bottom Fig. 2: vapor tight tank 6 that the framework with lower screen body 9 is integrated, the most isometrical multiple hole is arranged at bottom, its
Middle macropore is evacuation, fresh air inlet, and aperture is siege leghole, and siege column penetrates in vapor tight tank 6, holds up material
Dish.
The air cooling system of the present invention is to be made up of motor, impeller, heat exchanger 14 and an operated pneumatic valve 13, sees
Fig. 3, it is characterised in that add one between backwind tube 12 and the heat exchanger 14 of connection vacuum degreasing furnace shell
Individual operated pneumatic valve 13, the effect of this operated pneumatic valve 13 is that the treating gas in prevention vapor tight tank 6 is through air-cooled
System；When air-cooled, this operated pneumatic valve 13 is in opening, when equipment is evacuating and the mistake of degumming
Cheng Shi, this operated pneumatic valve 13 is in closed mode, produced gas when being so possible to prevent degumming
Enter in air cooling system, pollute heat exchanger 14 and miscellaneous part.Blower fan 15 export by air-cooled pipeline 16 with
Triplate line 17 is connected.The vacuum pump set part of vacuum system, is shown in Fig. 4, it is characterised in that with triplate line
The 17 evacuation pipeline front ends being connected connect a filtering tank 19, connect vacuum pump set 18 again, and filtering tank 19 is used for
Collect the impurity and other materials produced in product sintering skimming processes, it is to avoid these impurity enters vacuum pump 20
In, damage vacuum pump 20.Another measure antipollution: be provided with heater on triplate line 17, can be right
Pipeline heats, and the glue gas preventing equipment from getting off in stove during defat meets condensation knot, blocking pipeline.
Program robot control system(RCS) is arranged by work flow: see Fig. 5, opens vacuum pump set 18, takes out in equipment
Empty；Now the operated pneumatic valve 13 between backwind tube 12 and heat exchanger 14 is closed, when vacuum reaches
During to heating requirements, begin to warm up；It it is now evacuation limit, limit heated condition；When temperature reaches the temperature of product degumming
When spending, product starts degumming, owing to being also carried out evacuating at the same time, thus by the glue that produces in product from
Evacuation pipeline is extracted out, enters in the filtering tank 19 before vacuum pump set 18.After product degumming terminates, stop taking out
Sky, pours cooling gas, the simultaneously operated pneumatic valve 13 between backwind tube 12 and heat exchanger 14 and wind in stove
Door 3 automatically opens up, and when reaching blower fan 15 in stove and starting pressure, it is air-cooled that blower fan 15 starts beginning, until temperature
Stopping when degree is cooled to open the door, open furnace shell upper cover 2 feeding, whole process operation terminates.
Upper screen body 4 air door 3 above: when carrying out evacuating, heated and degumming by heater 8 in heating chamber 7
Time, this air door 3 is in closed mode, is so conducive to the insulation of heating chamber 7.When air-cooled, this
Air door 3 is in opening, and wind enters from the bottom of heating chamber 7, four pores of this air door 3 from top
Flowing out, air cooling effect is good, and efficiency is high.During carrying out charging and feeding, the upper screen body 4 of heating chamber 7
Move together with furnace shell upper cover 2 with the top cover 5 of vapor tight tank 6.
