Barn circulating fumigation system

Abstract

The invention discloses a barn circulating fumigation system which comprises one or more groups of circulating fumigation systems, wherein each system comprises a fan, and one end of the fan is connected with a flexible pipe; the other end of the flexible pipe is connected with two or more pipelines, and the other end of each pipeline is connected with an automatic regulator; each automatic regulator is connected with a medicine chest through a pipeline and connected with a gas detection chest through an electric wire, and the gas detection chest is connected with a plurality of gas pipes through a main gas pipe. The circulating fumigation system can effectively solve the fumigation problem of high grain pile bulk storage, the fan is effectively protected when being overloaded, and the service life of the fan is prolonged. Medicine is put out of a barn, so that the contact between operators and toxic agents is reduced, and the healthy and safety of the operators is protected. The content of hydrogen phosphide in the barn can be monitored in time, the information is fed back to the automatic regulator, and the air volume is regulated so that the content of hydrogen phosphide achieves the optimal value. The medicament is saved, and the effect is enhanced.

Description

technical field [0001] The invention relates to a circulation fumigation system, in particular to a granary circulation fumigation system. Background technique [0002] my country is a big grain country, and the requirements for grain storage equipment are even more refined, and more attention is paid to the quality of grain storage. Achieve green and healthy grain storage. [0003] The circulation system refers to the use of the air duct in the warehouse as a poisonous gas diffuser, and through the circulation pipe installed on the warehouse wall or in the warehouse, the fan, the sprayer, the poisonous gas diffuser (air duct) and the grain pile are connected into a closed system. The method of using a circulation system to apply poisonous gas to control harmful organisms is called circulation fumigation. [0004] In recent years, the bulk storage of about 6m high grain piles in flat warehouses has become a common storage method in my country. It not only improves the uti...

AI Technical Summary

Problems solved by technology

Since the penetration capacity of phosphine is about 3m, it is difficult for phosphine to be evenly distributed in the 6m-high grain pile during fumigation, which brings certain difficulties to fumigate and kill insects in bulk storage of high grain piles

If the commonly used probes in the warehouse are deeply buried, small cloth bag cuttings are used, and pesticides are injected in the air duct, etc., the operation time will be too long, and the operators will be directly exposed to more poisons, which will affect the health of the grain preservation personnel.

At the same time, only relying on the natural diffusion of phosphine gas, it is difficult to combine phosphine to distribute evenly in the grain pile, and the purpose of completely killing pests cannot be achieved.
