Embodiment 1
[0021] In Example 1, a gasifier with a specification of 250 square meters per hour was selected, and the pipe was a stainless steel pipe with a diameter of DN50. The following data was obtained according to actual measurement.
[0022]
[0023] Statistical analysis of the above data yields the formula T=K*F / S, where T represents the outlet set temperature, F represents the opening ratio of the flow control valve, S represents the instantaneous flow, K is the variable coefficient, and the variable coefficient and work The pressure is related, and its value is 15 at a working pressure of 0.2MPa.
[0024] After actual measurement of the controlled atmosphere storage control mechanism of this structure, when the working pressure is set, only the opening degree of the valve port of the flow control valve needs to be adjusted to automatically control the intake of carbon dioxide cryogenic liquid at the inlet of the vaporizer. Effectively regulate the outlet temperature.
[0025] The PLC c...

The invention discloses a novel controlled atmosphere grain-storage control mechanism, which comprises a gasifier and an air outlet, and a flow control valve is arranged on a pipeline between the gasifier and the air outlet, a temperature monitoring device is disposed between the flow control valve and the air outlet and near the air outlet, and the flow control valve and a temperature monitoringdevice are respectively connected to a PLC control system. By adopting a control structure of the structure, the temperature of the air outlet can be controlled simply and effectively, so that the effect of the controlled atmosphere grain storage is ensured. The mechanism has the advantages of simple structure, low production cost and maintenance cost, and is convenient to use.
Description
Technical field [0001] The invention relates to the field of grain storage, in particular to a convenient and efficient novel controlled atmosphere storage grain control mechanism. Background technique [0002] Grain is often infected with insect pests and the quality of the food during the storage process, which causes the loss or quality of the food and is not suitable for consumption. At present, in order to ensure the safety of grain storage, most grain storage depots use phosphine fumigation technology for insecticide treatment on grain piles. However, the use of phosphine fumigation and insecticide treatment will not only leave chemical substances in the grain, but also cause harm to the health of the operators of fumigation and insecticide. Moreover, long-term use of phosphine fumigation to kill insects will make stored grain insects resistant. [0003] With the continuous improvement of people's living standards, people pay more and more attention to the living environmen...
