Description

Anticorrosive vacuum drying oven Technical Field The utility model relates to the technical field of vacuum drying boxes, in particular to an anti-corrosion vacuum drying box. Background The vacuum drying oven is a device specially designed for drying heat-sensitive, easily-decomposed and easily-oxidized substances, and is widely applied to the research application fields of biochemistry, chemical pharmacy, medical and health, agricultural scientific research, environmental protection and the like, in the drying process, the dried substances volatilize acidic or alkaline substances and the like, for example, acidic substances can be volatilized in the drying process of polypeptides, alkaline substances can be volatilized in the drying process of amine substances such as ethylamine, aniline and the like, the inner wall of the oven is corroded, the service life is influenced, in order to prevent the inner wall of the oven from being corroded, the surface of the oven is usually coated with an anti-corrosion layer, and due to the damage of the anti-corrosion layer, an operator can only observe whether the anti-corrosion layer is damaged and repair or replacement is carried out on the anti-corrosion layer through naked eyes after a period of use, however, manual detection can only be carried out after the drying is finished, real-time detection can not be carried out, the accuracy of naked eye observation is low, and the anti-corrosion layer cannot be observed by naked eyes when the anti-corrosion layer is damaged, and early warning is not possible. Disclosure of utility model The utility model provides an anti-corrosion vacuum drying oven which can solve the technical problems. The utility model is realized by the following technical scheme: an anti-corrosion vacuum drying oven comprises a body, an inner wall of the body, a fiber grating sensor, a controller and a prompter, The inner wall of the body is provided with an anti-corrosion layer, the fiber grating sensor is arranged on one side, close to the inner wall of the body, of the anti-corrosion layer so as to detect thickness change of the anti-corrosion layer, the input end of the controller is connected with the fiber grating sensor so as to receive signals output by the fiber grating sensor, and the output end of the controller is connected with the prompter. Further, the fiber bragg grating sensor array is arranged. Further, the anti-corrosion layer is a polytetrafluoroethylene layer or a soluble polyvinyl fluoride layer. Further, the thickness of the anti-corrosion layer is 0.4 mm-0.7 mm. Further, the anti-corrosion layer is a titanium alloy layer. Further, the thickness of the anti-corrosion layer is 0.5 mm-1 mm. Further, the prompter comprises a voice prompter and/or an indicator light. Further, the anti-corrosion device further comprises a protection plate, the anti-corrosion layer is arranged on the protection plate, the fiber bragg grating sensor is arranged between the inner wall of the body and the protection plate, and the protection plate is detachably connected with the inner wall of the body. Compared with the prior art, the utility model has the following advantages and beneficial effects: The utility model provides an anticorrosive vacuum drying cabinet, including the box, the anticorrosion layer, fiber bragg grating sensor, a controller and prompter, when the anticorrosion layer in the box of drying cabinet thins or damages because of wearing and tearing or corruption, fiber bragg grating sensor can judge the thickness variation of anticorrosion layer through detecting wavelength variation, fiber bragg grating sensor detects that the thickness of anticorrosion layer is less than the thickness that needs restoration or change, fiber bragg grating sensor transmits this signal to the controller, the controller exports this signal to the prompter, the suggestion staff restores and changes the anticorrosion layer, need not to wait to accomplish the drying and whether the rethread artifical naked eye observes the anticorrosion layer and damaged, real-time detection anticorrosion layer's thickness variation early warning in advance, suggestion staff in time restores or changes the anticorrosion layer, accuracy and the timeliness of judgement have been improved.
