Multi-layer blowing combined drying device

Abstract

The invention relates to a multi-layer blowing combined drying device. The device comprises a case, wherein a plurality of drying layers and a plurality of air duct layers are combined at intervals to form a multi-layer structure in the front of the case, a control device installation layer comprises a control system, a combined hot-air device is arranged at the rear of the inside of the case, each of the drying layers is a sealed drying region, each of the drying regions comprises a plurality of drying chambers, sealing doors of the sealing chambers are arranged on the front plate of the case, a motor of a rotary base of the combined hot-air device is controlled through the control system, the combined hot-air device rotates back and forth along a sector region and blows hot air in a round scanning mode, a temperature sensor and a humidity sensor collect temperature and humidity data signals, a single-chip microcomputer program compares the temperature data with the humidity data in accordance with the setting, and the temperature and the humidity of a plurality of drying chambers of corresponding drying regions are controlled within a set value and remain constant.

Description

technical field [0001] The invention relates to drying equipment, in particular to a multi-layer air-supply combined drying equipment, which is used for drying and storing chemical raw material samples and desiccant in commodity quarantine and inspection departments. Background technique [0002] At present, in the process of commodity quarantine inspection, it is necessary to dry and store various chemical raw material samples. Desiccant is a kind of highly active adsorption material. Silica gel desiccant has high adsorption performance, good thermal stability, stable chemical properties, and high Mechanical strength, silica gel desiccant plays an important role in the process of analytical chemical experiments. Silica gel desiccant can be used repeatedly. After moisture absorption, silica gel desiccant usually uses drying equipment to evaporate water at 100 ° C. After drying, silica gel desiccant It needs to be kept dry. The storage and transfer of silica gel desi...

Problems solved by technology

[0003] The determination of the chemical properties of various chemical raw material samples needs to be carried out under certain temperature and humidity conditions. Due to the large variety, small quantity and different chemical properties of various chemical raw material samples used for commodity inspection, they cannot be mixed in the same container. However, it is too scattered and not convenient for inspection operation, so it is necessary to design a drying device with a multi-box structure, which can store various samples with many varieties, small quantities, and different chemical properties in a centralized manner without confusing each other. Moreover, different drying and storage spaces are provided for different types of samples, and the drying speed, drying temperature and drying time can be controlled respectively according to the properties of different types of samples. At present, no effective improvement has been seen in this field. Solutions with technical flaws
