Double-wall thermal-insulation steel silo

Abstract

The invention discloses a double-wall thermal-insulation steel silo for storing foods. The lower part of a silo body is fixed on a support; the silo body comprises an inner plate and an outer plate; the inner and outer plates are interconnected through a bolt connecting pair; a thermal-insulation layer is clamped between the inner and outer plates; and a plurality of inner ring beams and a plurality of outer ring beams are arranged on the inner side of the inner plate and the outer side of the outer plate along a height direction respectively. The cross section of the inner plate is shaped like a smooth arc, the cross section of the outer plate is shaped like a continuous trapezoid, and the bolt connecting pair passes through a trough position of the outer plate, the thermal-insulation layer and the inner plate in sequence to connect and fasten the outer plate, the thermal-insulation layer and the inner plate. The inner ring beams are shaped like round hoops and adhered to and connected with the inner plate; and the longitudinal section of the outer ring beams is shaped like a trapezoid which is low on two sides and high in the middle, and the bottom surfaces on the two sides are connected to a wave crest of the outer side of the outer plate. The silo has a simple structure, saves use amount of steel, is convenient to construct and has a good thermal-insulation effect; a horizontal pressure of a bulk material in the silo is born by the inner plate, and a vertical friction force applied by the bulk material on a silo wall and a wind load, a snow load and the like applied to the silo and the like are born by a common stressed system consisting of the inner and the outer plates.

Description

technical field [0001] The invention relates to a grain steel plate silo, in particular to a double-walled steel thermal insulation silo which is used for storing grain bulk materials and has a circular cross-sectional shape. Background technique [0002] my country is a large agricultural country. With the bumper harvests in successive years of agricultural production, the problem of grain storage has been paid more and more attention by governments at all levels. The silo structure used to store grain is mainly divided into two types: reinforced concrete silo and steel silo. Compared with reinforced concrete silos, steel silos have the advantages of low cost, light weight, short construction period, and reusability. Gradually promoted, steel silos with transfer and storage functions have been more and more widely used. [0003] Most of the current steel silos are single-layer thin-walled silos without insulation structures. The walls of the silos are thin, the temperatur...

AI Technical Summary

Problems solved by technology

[0003]Most of the current steel silos are single-layer thin-walled silos without insulation structures. The walls of the silos are thin, the temperature difference between the inside and the outside is easy to form, and they are affected by external factors such as sunlight. , climate, etc., the phenomenon of condensation, the uneven temperature distribution of grain piles, etc., these factors bring some difficulties to the safe storage of grain
