Abstract
The utility model discloses a convection type vacuum drying oven, which comprises an oven body (1), a vacuum pump (7), a vacuum meter, a digital temperature controller and a heater, wherein the oven body (1) is provided with an exhaust port (2), and the exhaust port (2) is connected with the vacuum pump (7) through an exhaust pipeline; a normally-closed air inlet pipe (4) is arranged on the exhaust pipeline, and an exhaust valve (5) is arranged at the connecting end of the exhaust pipeline and the vacuum pump (7); and an air inlet (3) is arranged in the oven body (1), and the air inlet (3) is connected with a gas storage device through an air inlet pipeline. The air inlet pipeline is added in the drying oven, convection is formed in the oven body by introducing inert gas or dry air, and gas evaporated from a sample is extracted, so that the drying efficiency and the drying effect are improved.
Description
Technical field
The utility model relates to a kind of vacuum drying chamber, is specifically related to the convection type vacuum drying chamber of a kind of Yi Chao of being used for, oxidizable material.
Background technology
At present, the vacuum drying chamber of selling on the market now has many styles, model and specification, and also there are tens families in manufacturer, though each producer's product is different, general structure is the same basically with principle.Be about to sample and put into vacuum environment, carry out heat drying, mainly utilize vavuum pump to bleed, make to form vacuum state in the operating room, reduce the boiling point of solvent, accelerate dry speed.
Existing vacuum drying chamber basically all is an airtight casing, and there is individual aspirating hole the side of casing, and there is an intake valve casing front, a vacuum meter and a digital temperature controller.The vacuum drying chamber of selling on the market now, after vacuumizing, the space in the casing is airtight; In the dry run of carrying out sample, the solvent in the sample constantly gets into casing, and the air pressure in the casing is improved constantly; Influenced the solvent in the sample like this and continued evaporation, caused rate of drying slow, thereby influence operating efficiency; Especially when the strong sample of dry some easy oxidation, moisture absorption, can not in dry run, unpack again and take a breath, existing equipment is difficult to this difficult problem of solution.
The utility model content
The utility model provides a kind of convection type vacuum drying chamber, has solved slow, the ineffective problem of rate of drying in the prior art.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of convection type vacuum drying chamber comprises casing, vavuum pump, vacuum meter, digital temperature control device and heater, and bleeding point is set on the casing, and bleeding point is connected with vavuum pump through exhaust pipe; Exhaust pipe is provided with normally closed air inlet pipe, and exhaust pipe and vavuum pump link are provided with evacuating valve; Also be provided with air inlet in the casing, air inlet is connected with the gas storage device through air inlet pipeline, dress inert gas or dry air in the gas storage device; Said bleeding point is located at bottom half, and air inlet is located at the casing top.
Further technical scheme is, an end that is connected with the gas storage device on the above-mentioned air inlet pipeline is provided with air intake valve, and other end exit is provided with a metal catch.
Compared with prior art; The beneficial effect of the utility model is: the utility model has increased air inlet pipeline, through feeding inert gas or dry air, in casing, forms convection current; Extract out evaporating the gas that in the sample; Thereby improved drying efficiency and drying effect, compared with common drying box and shortened 20% drying time, drying efficiency has improved 15%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1-casing, 2-bleeding point, 3-air inlet, 4-air inlet pipe, 5-evacuating valve, 6-air intake valve, 7-vavuum pump.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified, but the embodiment of the utility model is not limited thereto.
Like the described a kind of convection type vacuum drying chamber of Fig. 1, comprise casing 1, vavuum pump 7, vacuum meter, digital temperature control device and heater, bleeding point 2 is set on the casing 1, bleeding point 2 is connected with vavuum pump 7 through exhaust pipe; Exhaust pipe is provided with normally closed air inlet pipe 4, and exhaust pipe and vavuum pump 7 links are provided with evacuating valve 5; Also be provided with air inlet 3 in the casing 1, air inlet 3 is connected with the gas storage device through air inlet pipeline, and the gas of adorning is nitrogen in the gas storage device; Bleeding point 2 is in the bottom of casing 1, and air inlet 3 is at the top of casing 1; An end that is connected with the gas storage device on the air inlet pipeline is provided with air intake valve 6, and other end exit is provided with a metal catch.
The sample that needs are dry is put into vacuum chamber 1, closes the door of vacuum drying chamber, closes air inlet pipe 4; Close air intake valve 6, open evacuating valve 5, open vacuum pump 7; After being evacuated down to certain value, certain hour, open air intake valve 6, regulate the air inflow of nitrogen; And to keep vavuum pump 7 be opening, keeps the interior negative pressure of vacuum drying casing; Heat with digital temperature control device control heater behind the certain hour.After 6 hours, close evacuating valve 5, close vavuum pump 7, treat that the vacuum drying chamber internal gas pressure is at 0 o'clock, close air intake valve 6, take out sample and get final product.
Claims (2)
1. convection type vacuum drying chamber; Comprise casing (1), vavuum pump (7), vacuum meter, digital temperature control device and heater; Bleeding point (2) is set on the casing (1); Bleeding point (2) is connected with vavuum pump (7) through exhaust pipe, and it is characterized in that: said exhaust pipe is provided with normally closed air inlet pipe (4), and exhaust pipe and vavuum pump (7) link is provided with evacuating valve (5); Also be provided with air inlet (3) in the said casing (1), air inlet (3) is connected with the gas storage device through air inlet pipeline; Said bleeding point (2) is located at casing (1) bottom, and air inlet (3) is located at the top of casing (1).
