Vacuum no-oxygen bulk grain warehouse

Abstract

A vacuum oxygen-free bulk barn is characterized in that a barn body and a barn cover used for sealing the barn body are surrounded into the barn; a seal ring is arranged at the connection part between the barn body and the barn cover, a suction opening is arranged on the barn, the barn cover is sealed and airtight during grain storage, and the suction opening is connected with an exhaust fan after the grain is stored and the barn cover is covered, the inner part of the barn body is vacuumized to cause the barn to be in an oxygen-free state. The vacuum oxygen-free bulk barn has the advantages that the aging speed of the grain can be delayed in the process of grain storage, thus ensuring the grain quality and realizing pollution-free grain storage; loading and unloading of the grain for in-and-out warehouse are convenient in the process of grain transport; and the vacuum oxygen-free bulk barn also has the advantages of reducing the packaging link, low requirements for the storehouse, being capable of realizing flow and simplification of grain transport, and realizing rapid, simple and low cost transport of grain logistics.

Description

technical field [0001] The invention relates to the technical field of grain storage and transportation equipment, in particular to a vacuum anaerobic bulk grain silo. Background technique [0002] At present, the storage of my country's grain (including grains and beans) is mainly undertaken by two aspects: [0003] 1. Farmers’ household grain storage adopts traditional storage methods. 1. Store grain in grain barrels, or dry grain and pack it in sacks or woven bags and place it in the family warehouse. This storage method is simple and simple. The technology is backward, and it is very easy for the grain to suffer from stored grain pests or be eaten by mice. According to the statistics of the State Grain Administration, my country’s traditional grain storage method has a huge loss of grain, with a loss rate of 8% to 12%. The annual loss due to improper grain storage methods reaches more than 10 billion catties, which is equivalent to 12 million mu of high-standard grain f...

AI Technical Summary

Problems solved by technology

2. At present, the relatively advanced grain storage method for farmers in China is the small granary for farmers promoted in Sichuan. The granary with this structure is installed and stored in a fixed manner. Although it can effectively prevent rodent damage, and it is more convenient for farmers to store and take out, However, it still adopts the traditional drug fumigation method to prevent stored grain pests. Due to the poor conditions of farmers’ warehouses, it is difficult for ordinary farmers to use fumigation drugs in strict accordance with the regulations, resulting in drug abuse, which is very easy to cause drug pollution. Even drug injuries

Drug fumigation is mainly used for the prevention and control of stored grain pests. In recent years, nitrogen or carbon dioxide filling has also been used to eliminate insects. However, this method has high requirements for warehouse conditions. The method of drug fumigation will leave residues in the grain, which is not environmentally friendly and has not been realized. Green storage of grain, and the cost of pest control by filling nitrogen or carbon dioxide is high, and the cost of repacking when grain is stored in bulk is high

2. The method of packaging and storing grain has the advantages of convenient loading and unloading of grain in and out of the warehouse, and the advantages of reducing packaging links, and it does not have high requirements for warehouse conditions. Ventilation (including mechanical ventilation) is also used for temperature control, but the pest control of stored grain mainly adopts The way of drug fumigation, there will be drug residues in the grain, which is not environmentally friendly, and the green storage of grain has not been realized, and the utilization rate of the warehouse is low, and it takes a certain amount of money to pack the grain with gunny bags or woven bags

However, there are also the following problems: 1. Repeated loading and unloading, resulting in food damage and lower quality; 2. The cost of returning vehicles and ships empty-loaded is high, and idle equipment during port pressure and off-season operations will bring intangible losses; 3. To be able to mobilize enough The port tributary fees that need to be paid for the inventory, the large amount of funds occupied by the bulk inventory and the interest paid for it; 4. The cost of implementing monitoring measures to prevent dust explosions

In addition, the initial investment in bulk distribution is huge, and the maintenance and maintenance after completion is not a small expense.

More importantly, my country's grain production methods are mainly scattered farmers' independent production, and there are very few standardized and large-scale production methods. No one has the ability to invest in bulk handling and transportation equipment, so it is difficult to promote and not suitable for market demand
