Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model vacuum drying chamber comprises casing 1, air extractor 11, drying bottle 10, inert gas bottle 9 and microcomputer controller 3.Casing 1 inside is provided with 6 dry sub-chamber 4, (can arrange multiple as required, can single sided matrix distribute in 2*3 matrix distribution, also can double-sided matrix distribute, ensure that sub-chamber's closing door 6 in each dry sub-chamber front is located at the outside of casing 1, be easy to open).Casing 1 inwall is provided with insulating interlayer 2, is also provided with insulating interlayer 7 between each dry sub-chamber.Microcomputer controller adopts KL-1PC-3 intelligent controller; Outside employing VD53/115 control panel.Air extractor 11 is connected with drying bottle 10.Each dry sub-chamber 4 is connected with drying bottle 10, inert gas bottle 9 respectively by the pump-line of correspondence, admission line.Sensor 46 and lighting tube 42 is equipped with in each dry sub-chamber 4.Sensor 46 comprises temperature sensor and pressure sensor.Temperature sensor adopts model to be the integrated temperature sensor of KZW-JPT, and pressure sensor adopts TS130 mesohigh pressure sensor.Each dry sub-chamber 4 inwall left and right sides is respectively equipped with heating tube 43, and bottom is provided with heating tube 44.Bottom in each dry sub-chamber 4, the top of heating tube 44 are equipped with pallet 45.As shown in Figure 2, pallet 45 is (also can be netted) in paliform, facilitates the hot gas of heating tube 44 to rise, accelerate dry materials.The inner upper of each dry sub-chamber 4 is equipped with gas buffer passage 41, is connected with corresponding pump-line by gas buffer passage 41 with admission line.As shown in Figure 3, gas buffer passage 41 inside is provided with multiple passage 411, and passage 411 upper end is cylindrical, and lower end is conical (upper end section is less than lower large end section), avoids directly to the impact to material when passing into gas in dry sub-chamber.Each pump-line is equipped with evacuating valve 12, each admission line is equipped with air intake valve 8.Evacuating valve 12 and air intake valve 8 all adopt electric valve.Each dry sub-chamber 4 front, be respectively equipped with sub-chamber's closing door 6 corresponding to casing 1 outside.Sub-chamber's closing door 6 is provided with toughened glass window 5, conveniently observes.Microcomputer controller 3 respectively with the sensor 46 in each dry sub-chamber, heating tube 43,44, each evacuating valve 12, each air intake valve 8 and air extractor 11 be connected, control heating, vacuumize and be filled with inert gas.
During use, material to be dried is placed on the pallet 45 in dry sub-chamber 4, close sub-chamber's closing door 6, the pressure of this chamber is set on microcomputer controller 3, temperature, inert gas and drying time, then start, evacuating valve 12 on the pump-line that this dry sub-chamber 4 is connected is opened, air extractor 11 is started working and is bled, pressure sensor induction pressure reaches setting value, stopping is bled, evacuating valve 12 is closed, heating tube 43, 44 start heating, in dry sub-chamber 4, firing rate is fast and even, temperature sensor senses temperature stops heating when reaching setting value, utilize insulating interlayer 2, 7 are incubated.In material during moisture evaporation, pressure raises, and microcomputer controller 3 is opened by controlling evacuating valve 12 after pressure sensor induction, and controls air extractor 11 and again bleed, and stops after reaching setting pressure; If temperature declines to some extent, microcomputer controller 3 controls heating tube 43 and 44 and again starts heating.When drying terminates or need to pass into inert gas, the air intake valve 8 that microcomputer controller 3 controls on admission line that sub-chamber 4 dry with this be connected is opened, inert gas bottle 9 passes through air intake valve 8 to this dry sub-chamber 4 air inlet, gas, by the cushioning effect of buffer channel 41, can not have large percussion to material to be dried.When the situation of the sub-chamber that will see drying, lighting tube 42 can be opened and throw light on, be observed by toughened glass window 5.
