Problems solved by technology

During the aging process of tobacco leaves, there are the following three problems: one is that the tobacco leaves are prone to insects; It is easy to brown and darken; it not only causes serious losses to the tobacco industry, it is understood that the loss of tobacco leaves after alcoholization is roughly 0.8%-1% (or even higher) per year, and the direct economic loss caused by a medium-sized cigarette factory in one year reaches 2000 It also seriously affects the internal and external quality of tobacco leaves, which in turn affects the quality of tobacco

Embodiment 1

[0036] like Figure 1~5As shown, this embodiment provides an isolated gas type gas concentration monitor, including a closed casing 1, a control device 26 and a combined monitoring device, the closed casing includes a face casing 2, a rear cover 3 and a lower bottom plate 4, and the rear cover 3 It is connected to the rear of the face shell 2, and the lower bottom plate 4 is connected to the bottom of the face shell 2; the combined monitoring device includes a large-range low-precision monitoring device 5 and a small-range high-precision monitoring device 6, a large-range low-precision monitoring device 5 and a small-range monitoring device 5 The high-precision monitoring devices 6 are installed side by side on the lower bottom plate 4 , the control device 26 is placed inside the airtight casing 1 , and the large-range low-precision monitoring device 5 and the small-range high-precision monitoring device 6 are signally connected to the control device 26 respectively. When the ...

Embodiment 2

[0049] In order to meet the gas monitoring requirements in different application environments, such as Image 6 As shown, in this embodiment, a threaded installation hole 18 is further provided on the rear cover 3 , and the threaded installation hole 18 is used for installing the core-spun monitoring component 19 .

[0050] like Figure 6-9 As shown, the core-spun monitoring assembly 19 includes a hollow shaft 20 and a monitoring assembly 21. The front end of the hollow shaft 20 is preferably threadedly connected with the threaded mounting hole 18, and a sealing ring structure is provided between the front end of the hollow shaft 20 and the threaded mounting hole 18, like Figure 8 As shown, two layers of seals are provided between the hollow shaft 20 and the threaded mounting hole 18; such as Figure 7-9 As shown, the above-mentioned monitoring assembly 21 includes a temperature and humidity monitoring component 22, a spacer 23, a large-range low-precision monitoring compon...

Abstract

The invention discloses a gas isolation type gas concentration monitor. The gas isolation type gas concentration monitor comprises an airtight shell, a control device and a combined monitoring device,wherein the combined monitoring device comprises a wide-range low-precision monitoring device and a narrow-range high-precision monitoring device, the wide-range low-precision monitoring device and the narrow-range high-precision monitoring device are arranged on a lower bottom plate side by side, the control device is arranged in the airtight shell, the wide-range low-precision monitoring deviceand the narrow-range high-precision monitoring device are in signal connection with the control device separately, and a monitoring component of the narrow-range high-precision monitoring device canbe not in contact with the gas at the outer side under the control of the control device. Through the design of the wide-range low-precision monitoring device and the narrow-range high-precision monitoring device, gas concentration monitoring parts of different ranges can be targetedly used for monitoring the gaseous environment under different gas concentration conditions, the application range is wide, the monitoring precision is high, the existing high requirement for gas concentration monitoring can be met, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to an isolated gas type gas concentration monitor. Background technique [0002] Long-term storage of crops needs to solve problems such as insects and mildew. Taking tobacco leaves as an example, in order to improve the quality of cigarettes during tobacco processing, it usually takes 1-3 years of natural aging. During the aging process of tobacco leaves, there are the following three problems: one is that the tobacco leaves are prone to insects; It is easy to brown and darken; it not only causes serious losses to the tobacco industry, it is understood that the loss of tobacco leaves after alcoholization is roughly 0.8%-1% (or even higher) per year, and the direct economic loss caused by a medium-sized cigarette factory in one year reaches 2000 More than 10,000, but also seriously affect the internal and external quality of tobacco leaves, and then affect the quali...
