Transverse-circulation ventilating device

Abstract

The invention discloses a transverse-circulation ventilating device. The transverse-circulation ventilating device comprises two horizontal main air passages, two ventilation openings, a plurality of vertical air passages, two vertical circulating pipelines, a transverse circulating pipeline, an air blower, air valves and a control cabinet, wherein the two horizontal main air passages are arranged at lower parts of inner sides of two opposite wall bodies of a granary in horizontal symmetry; the two ventilation openings are symmetrically formed in outer sides of the wall bodies, one side, close to the corresponding wall, of each ventilation opening communicates with the middle part of the corresponding horizontal main air passage through a wall pipe, and the other side of each ventilation opening is provided with a sealing door controlled by a ventilation opening executor; the vertical air passages are arranged above the horizontal main air passages in vertical symmetry and communicate with the horizontal main air passages, and first openings are formed in the vertical air passages; the two vertical circulating pipelines are arranged above the ventilation openings in vertical symmetry and communicate with the ventilation openings; one end of the transverse circulating pipeline communicates with one vertical circulating pipeline, and the other end of the transverse circulating pipeline communicates with the other vertical circulating pipeline through a circulating blower; the air blower is arranged inside the ventilation opening which is homolateral to the circulating blower; and the control cabinet is electrically connected with the air valves, the air blower, the circulating blower and the ventilation opening executors. The transverse-circulation ventilating device has the advantages of simple structure, high degree of automation, good use effect and the like.

Description

technical field [0001] The invention relates to the field of grain ventilation equipment. More specifically, the present invention relates to a transverse circulation ventilation device. Background technique [0002] Mechanical ventilation for grain storage is a grain preservation technology commonly used in the grain storage or grain reserve industry. The parameters of the gas medium in the pile can be adjusted to adjust the temperature and humidity of the grain pile, so as to achieve the purpose of safe storage of grain or improving the quality of processing technology. At present, most of the mechanical ventilation in my country's grain storage industry adopts the vertical ventilation technology of air flow upward or downward. This technology has the disadvantages of low efficiency of storage rotation logistics, serious ventilation loss rate, insufficient uniformity of cooling and fumigation, and The daily storage workload is large, and the use and maintenance costs are ...

AI Technical Summary

Problems solved by technology

However, in the ventilation system of the above-mentioned patent, the fan needs to be manually turned on, and the horizontal ventilation or horizontal circulation ventilation of the granary is realized by changing the connection mode between the fan and the ventilation duct. Moreover, in the ventilation system of the above-mentioned patent, the horizontal uniform ventilation can only be realized when the grain is full, and the horizontal uniform ventilation cannot be realized when the grain is loaded while the warehouse is full or the grain is not full.
