Compared with the prior art, the low-temperature tank has the following obvious effects: the design is reasonable, the structure is simple, the operation is convenient, the manufacturing cost is low, the volume is small and the movement is convenient.
Description
Technical field
The utility model relate to a kind of be used to place do the cryostat, of impact toughness test with sample.Need tested sample to reach specific low temperature owing to make the sample of impact toughness test, the utility model provides the cryostat, that makes sample reach specific low temperature.
Background technology
Being specifically designed to the equipment of placing the sample cryostat, in the prior art also has, but since structure comparatively complicacy and price comparison are high, general use enterprise does not have and does not accept; And the volume of this equipment is bigger, takies very big factory building space, and equipment all is fixed on a fixing position simultaneously, moves very inconvenience, moves once installation can't be gone basically again, brings inconvenience for the people who does experiment.Existing on the other hand equipment all adopts the cooled with liquid nitrogen method; Because the holding vessel volume of liquid nitrogen is bigger; So do all and charge into a large amount of nitrogen at every turn toward liquid nitrogen container; In general not to make sample in enormous quantities then all to too many or too much for use, after testing the time that do not use up then, can gasify yet, so waste very much resource.
The utility model content
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art; And provide a kind of reasonable in design, simple in structure, easy to operate; Cost of manufacture is low, and being used to place of the little conveniently moving of volume done the cryostat, of impact toughness test with sample.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used to place does the cryostat, of impact toughness test with sample; Comprise shell; It is characterized in that shell upper is provided with nitrogen storage tank and absolute ethyl alcohol holding vessel, outer casing underpart is provided with low-temperature mixed liquid incubator, and said nitrogen storage tank is through liquid nitrogen carrier pipe and low-temperature mixed liquid incubator UNICOM; The liquid nitrogen carrier pipe is provided with liquid nitrogen and carries valve; Said absolute ethyl alcohol holding vessel is through ethanol carrier pipe and low-temperature mixed liquid incubator UNICOM, and the ethanol carrier pipe is provided with ethanol and carries valve, is provided with the net grid that are used for placing sample in the said low-temperature mixed liquid incubator; Be separately installed with thermocouple temperature measuring apparatus and agitating device in the said low-temperature mixed liquid incubator, said thermocouple temperature measuring apparatus, agitating device are connected with controller.
The said agitating device of the utility model comprises stirring motor and agitator arm, and stirring motor is connected with agitator arm, and stirring motor is connected with controller.
The utility model also is provided with travelling car, and shell is installed on the travelling car.
The said liquid nitrogen of utility model carries valve and ethanol to carry valve to be magnetic valve, and liquid nitrogen carries valve, ethanol to carry valve all to be connected with controller.
The utility model compared with prior art has following positive effect: reasonable in design, simple in structure, easy to operate, cost of manufacture is low, the little conveniently moving of volume.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1; The utility model embodiment comprises travelling car 1, is installed in the stainless steel casing 2 on the travelling car 1; The top of said stainless steel casing 2 is provided with nitrogen storage tank 3 and absolute ethyl alcohol holding vessel 4; And the bottom of stainless steel casing 2 is provided with low-temperature mixed liquid incubator 5, and said nitrogen storage tank 3 is delivered to low-temperature mixed liquid incubator 5 through liquid nitrogen carrier pipe 31 with liquid nitrogen, and carries valve 32 to control the conveying break-make through liquid nitrogen; Said absolute ethyl alcohol holding vessel 4 is delivered to low-temperature mixed liquid incubator 5 through ethanol carrier pipe 41 with ethanol, and carries valve 42 to control the conveying break-make through ethanol; Be provided with the net grid 53 that are used for placing sample 52 in the said low-temperature mixed liquid incubator 5; Said low-temperature mixed liquid incubator 5 is separately installed with thermocouple temperature measuring apparatus 7 and agitating device 6; Said thermocouple temperature measuring apparatus 7 all is connected with controller 8 with agitating device 6; Said agitating device 6 comprises stirring motor 61 and agitator arm 62, and two kinds of mixing materials are stirred.
It is hand-operated valve or magnetic valve that the said liquid nitrogen of the utility model carries valve 32 to carry valve 42 with ethanol.
If it is magnetic valve that liquid nitrogen carries valve 32 to carry valve 42 with ethanol, then link to each other operation principle with controller 8 respectively: it is temperature required to set sample; Thermocouple temperature measuring apparatus 7 will carry out measurement data automatically and feed back to controller 8; Carry valve 32 and ethanol to carry valve 42 to carry corresponding composition like 8 of too high controllers of temperature through the control liquid nitrogen, control agitating device 6 then two kinds of mixing materials are stirred, then stop to carry when low temperature requires when temperature arrives; And by original sample temperature retention time of setting; Carry out timing through timer, as the time once to reporting to the police through alarm, let the staff take out sample.
The utility model controller 8 can adopt existing techniques in realizing, and intelligent PID temperature controller, alarm, timer, liquid nitrogen relay indicating light, absolute ethyl alcohol relay indicating light, stop button, start button, agitating device switch, power switch etc. can be set on the controller 8.
The utility model compared with prior art its advantage is:
Reasonable in design, simple in structure, easy to operate, cost of manufacture is low, and the little conveniently moving of volume can not wasted resource because the holding vessel volume is little.
Allly conceive equivalence or the simple change that described structure, characteristic and principle are done, include in the protection domain of the utility model patent according to the utility model patent.
