Technical field
The utility model relates to a kind of vacuum drying chamber, particularly a kind of automatic control type vacuum drying chamber, and it mainly is that various materials with thermal sensitivity, easily decomposition, easily oxidation are carried out drying, heat treated.
Background technology
Vacuum drying chamber is a kind of instrument that is exclusively used in dry goods.It is mainly used in scientific research, medical institutions, universities and colleges, industrial enterprise and all kinds of laboratory.Its principle is a dry goods under the condition of vacuum, can reduce dry temperature, avoids some special instruments because high temperature and oxidation avoids high temperature to kill biological cell simultaneously.Present vacuum drying chamber all is manual control generally, needs the staff to wait at any time.And vacuum degree control is difficult, and the level of vacuum in the casing all is to observe with vacuum meter, and the vacuum meter total indicator reading is not very accurate, and error ratio is bigger, is difficult for during work regulating.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, easy to operate, Based Intelligent Control, the automatic control type vacuum drying chamber that drying effect is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of automatic control type vacuum drying chamber, comprise casing, chamber door, vacuum extractor and control cabinet, be provided with inner bag in the casing, control cabinet is positioned at the below of casing, vacuum extractor is positioned at the below of control cabinet, it is characterized in that: be provided with shelf in the described inner bag, heater is fixed in the shelf; Described vacuum extractor comprise vavuum pump, vent valve and and magnetic valve; Described control cabinet comprises temperature controller and resistance vacuum gauge.
Be provided with sealing ring between casing described in the utility model and the chamber door; The installed inside of chamber door has safety glass, and the centre of chamber door is equipped with double-deck bulletproof glass form.
Between casing described in the utility model and the inner bag super glass wool is installed.
The utility model compared with prior art has following positive effect: reasonable in design, favorable sealing property, vacuum effectiveness good; Adopt high-precision digital temperature control device simultaneously, be more prone to set and probe temperature, make reading more accurate, resistance vacuum gauge can be controlled vacuum automatically according to the vacuum condition in the inner bag.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 casing, 2 control cabinets, 3 vavuum pumps, 4 magnetic valves, 5 vent valves, 6 resistance vacuum gauges, 7 knockers, 8 chamber doors, 9 shelves, 10 vavuum pump tube connectors, 11 temperature controllers, 12 inner bags.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1, present embodiment mainly is made up of casing 1, control cabinet 2, chamber door 8 and vacuum extractor, wherein is provided with inner bag 12 in the casing 1, is provided with shelf 9 in the inner bag 12, and heater is fixed on 9 li of shelves.Control cabinet 2 is positioned at the below of casing 1, and vacuum extractor is positioned at the below of control cabinet 2, and vacuum extractor comprises vavuum pump 3, vent valve 5 and magnetic valve 4.Control cabinet 2 comprises temperature controller 11 and resistance vacuum gauge 6.
In the present embodiment, the installed inside of chamber door 8 has safety glass, and the centre of chamber door 8 is equipped with double-deck bulletproof glass form, is convenient to the processing article that are dried in the inspection box.Be provided with sealing ring between casing 1 and the chamber door 8, chamber door 8 is provided with long column shape knocker 7, utilizes the spacing of regulating knocker 7 and thick safety glass like this, makes chamber door 8 can press rubber seal after shutting, and is air tight during with the assurance suction.
In the present embodiment, heater is fixed on 9 li of shelves, can the article on the shelf 9 directly be heated, and has reduced the loss of heat energy to greatest extent.
In the present embodiment, between casing 1 and the inner bag 12 super glass wool is installed, has strengthened effect of heat insulation.
In the present embodiment, temperature controller 11 adopts high-precision Intelligent Digital display regulator, is more prone to set and probe temperature, makes reading more accurate.
In the present embodiment, can regulate vacuum in the casing, control level of vacuum in the casing according to the needs of dry goods according to resistance vacuum gauge 6.As long as regulate resistance vacuum gauge 6 before use, the vacuum during work in the casing 1 just can be regulated automatically, the time article dryings carry out smoothly.
The present embodiment global shape is a cuboid, and volume is bigger, and the position of control cabinet 2 is positioned at the human body waist just, and control is convenient.
During use, chamber door 8 shut and knocker 7 screwed and put in place, close vent valve 5, opens solenoid valve 4.With vavuum pump tube connector 10 the bleed interface of vavuum pump 3 with vacuum drying chamber is connected firmly.Connect vavuum pump 3 power supplys, begin to bleed, when regulating resistance vacuum gauge 6 and making air pressure in the casing for-0.1Mpa, close vavuum pump 3 power supplys again after closing magnetic valve 4 earlier, flow back in the casing to prevent outside air, be in vacuum state in the casing 1 this moment.Open the vacuum tank power supply, regulate temperature controller 11, set the temperature in the casing 1, begin slow heating then.When measure temperature near or equal design temperature after, treat that again the operating room enters temperature constant state after 1 to 2 hour, article enter drying stage.After the dry end of article, powered-down is opened vent valve 5, and air is entered in the casing 1, when vacuum is 0 in the casing 1, opens chamber door 8.The article drying is finished.
In addition, need to prove, specific embodiment described in this specification, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
