Tobacco stack sealing device for pest control in storage of tobacco factory

Technical Field

The application relates to the technical field of tobacco plant storage pest control equipment, in particular to a tobacco stack sealing device for tobacco plant storage pest control.

Background

The tobacco leaf fumigation is a process of directly killing tobacco storage pests by using toxic chemical agents, and the active substances of the fumigation agent exist in gaseous molecules, can penetrate through fumigated objects and kill pests hidden in the interior of a smoke box (bag) and in gaps of a smoke bin, so that the tobacco leaf fumigation has the advantages of quick response and thorough prevention and control, and is the most effective measure for treating the tobacco storage pests at present. At present, fumigation implemented in the tobacco industry is mainly phosphine fumigation and sulfuryl fluoride fumigation. The closed tent fumigation has the advantages of small dosage of fumigant and small exhaust emission, can improve the effectiveness of fumigation, and is beneficial to safety and environmental protection. With the development of technology, technicians develop a novel low-toxicity sulfuryl fluoride fumigant, which has the advantages of broad-spectrum disinsection and low residue. And the carbon dioxide gas is mixed in the sulfuryl fluoride for fumigation, so that the fumigation effect can be ensured, the toxicity of the fumigant can be further reduced, and the production cost can be saved. When in use, the tobacco stack is sealed, and then the tobacco stack is filled with sulfuryl fluoride fumigant and then maintained for a period of time, so that pests in the tobacco stack are killed.

Aiming at the related technology, when fumigation is carried out on the tobacco stack, the concentration of sulfuryl fluoride in different positions in the tobacco stack is easy to be uneven due to the different densities of sulfuryl fluoride fumigant and carbon dioxide, so that pests in partial areas of the tobacco stack are not thoroughly killed, and the situation of repeated insect conditions is caused later.
