Low-temperature grain storage double-layer wall square silo and silo entering and exiting method

Abstract

The invention discloses a low-temperature grain storage double-layer wall square silo, and relates to the technical field of grain storage, the low-temperature grain storage double-layer wall square silo comprises a warehousing equipment layer, a grain storage layer and a delivery equipment layer, and the warehousing equipment layer is provided with a grain conveyor; the grain storage layer comprises a plurality of vertically and horizontally arranged grain storage units, each grain storage unit is a conical bottom bin, a bin inlet is formed in the top of each grain storage unit, a bin outlet is formed in the bottom of each grain storage unit, a plurality of scrapers are arranged in the bin outlet equipment layer, and the scrapers are in lap joint with a conveying belt to a belt conveyor in the middle of the bin outlet equipment layer; a discharge port of the grain conveyor is communicated with the warehouse inlet, and a warehouse outlet is communicated with the scraper conveyor; a waterproof layer I is arranged on the inner wall of the grain storage unit, and a waterproof layer II is arranged on the outer wall of the grain storage unit; the bottoms of the grain storage units are provided with first air openings, the upper portions of the grain storage units are provided with second air openings, and ventilation pipes communicated with the first air openings are distributed at the bottoms of the grain storage units. The square silo is convenient to go out in turns, higher in adaptability, large in overall grain storage capacity and high in land utilization efficiency; the waterproof and heat-insulating performance is excellent; and in-out bin and ventilation are all automatically operated, so that the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of grain storage bins, in particular to a double-walled square silo for low-temperature grain storage and a method for entering and leaving the bin. Background technique [0002] Grain is an important strategic reserve resource of the country, and the stable supply and reserve of grain is related to the livelihood of the people, so the safe reserve of grain is very important. my country is a big country with food consumption, and the use of granary reserves is also very large. At present, the most common types of storage silos in my country are the flat silo and the shallow round silo. The shallow round silo is a cylindrical granary with a high grain layer, a large single silo capacity, and a relatively small area. The thermal performance is poor, and the surface grains age quickly. Compared with the shallow round warehouse, the one-story warehouse has a lower land use efficiency, but its thermal insulation...

AI Technical Summary

Problems solved by technology

In order to further improve the efficiency of land use, warehouse operators have designed a new warehouse-type building warehouse. This warehouse type can make full use of the upper space, and the degree of mechanization is relatively high, and the heat insulation effect is relatively good. However, its requirements on the structure of the building High, the project cost is relatively high

[0003] At present, based on factors such as environmental protection requirements and labor costs in the storage field, the selection of grain warehouses requires a higher degree of mechanization. Among them, shallow round warehouses and vertical silos are more mature warehouse types. From the perspective of cost performance, the single warehouse The warehouse capacity is very high, which is more suitable for terminal transportation operations and processing plants. For the reserve warehouse, there is a requirement for rotation every year, so the practicability is not strong
