Annular blowing, drying and dehumidifying device and method applied to cold and hot stage and application

Abstract

The invention discloses an annular blowing, drying and dehumidifying device applied to a cold and hot stage. The device comprises an annular blowing device (1), rotary adjusting spray heads (2), an air inlet (3), an air channel distributor (4) and a fixed connecting frame (5), wherein the annular blowing device (1) can be detachably connected with a device to be blown, dried and dehumidified through the fixed connecting frame (5); and the rotary adjusting spray heads (2) are uniformly distributed on the annular blowing device (1) at intervals in the circumferential direction, and the rotary adjusting spray heads (2) can spray a blowing medium to blow a part to be blown, dried and dehumidified of the device. The device disclosed by the invention can be used for stably and uniformly spraying dry purge gas to a sample observation window of the whole cold and hot stage at a high speed, isolating indoor humid ambient air and preventing the sample observation window from fogging to influence the experiment of the cold and hot stage; and the device has the advantages of high efficiency, flexibility and low cost, and is suitable for various types and specifications of cold and hot stages and related instruments.

Description

technical field [0001] The invention belongs to the technical field of atmospheric science, in particular to an annular purge drying and dehumidification device, method and application applied to cold and hot stations. Background technique [0002] The cold and hot stage is a scientific research equipment widely used in professional fields such as geology, atmospheric science, material science, food science, and pharmacology. It can be used with optical microscopes, scanning electron microscopes, environmental scanning electron The combination of focusing Raman microscope, fluorescence microscope and other microscope equipment can be used in mineral inclusion testing, atmospheric ice nuclei determination, polymer material phase transition and morphological change, food freeze-drying preservation, drug freeze-drying structure analysis, etc. The equipment precisely controls the temperature of the platform through programming, rapidly heats or cools the sample, and observes and...

AI Technical Summary

Problems solved by technology

However, industrial-grade rotary dehumidifiers are expensive, occupy a large area, have high power, strong vibration, and high noise. They require a certain degree of indoor renovation, and the cost of manpower, time, and money is relatively high; while most indoor research laboratories have Ventilation requirements, faster air circulation, put forward higher requirements on the dehumidification capacity of the dehumidifier

[0007] To sum up, the existing method of using a dehumidifier to reduce the re
