Embodiment 1

[0042] The airtight and heat-insulating steel silo comprises: an inner cylinder, the inner cylinder includes a silo 1 and a silo roof 2, and the silo roof and the silo are connected by welding, and the connection structure is continuous welding. There is an insulation layer 3 on the outside of the inner cylinder, the inner cylinder is connected to the column 4, the outer cylinder 5 is on the outside of the insulation layer, and the roof of the warehouse is an integral welded structure.

Embodiment 2

[0044] In the above-mentioned airtight and heat-insulating steel silo, the silo is a wall of a spiral steel plate bite structure, and the upper and lower layers are connected by a spiral coiling machine, and the coiling structure at the position of the bite 10 is 5 layer or 7 layer mouth.

Embodiment 3

[0046] In the above-mentioned airtight and heat-insulating steel silo, the wall panels of the cylinder wall are connected by bolts to form an assembled cylinder wall, and the joints of the wall panels are attached with seals 6 . The sealing member 6 is a sealing film or a sealing plate, which is attached to the sealing port by a sealant.

Abstract

The invention provides an airtight heat preservation steel plate silo and a manufacturing method thereof. The steel plate silo is low in manufacturing cost, occupies small floor area and is easy for mechanical production; however, due to the poor airtightness, fumigating and inset killing cannot be carried out, thus, the steel plate silo is not suitable for being storinged for a long time. The airtight heat preservation steel plate silo comprises an internal cylinder body; the internal cylinder body comprises a silo cylinder (1) and a silo top (2); the silo top is connected with the silo cylinder through welding; and the connecting structure is continuously welded; a heat preservation layer (3) is arranged outside the internal cylinder body; the internal cylinder body is connected with an upright column (4); an external cylinder body (5) is arranged outside the heat preservation layer; and the silo top is an integrally welded structure. The airtight heat preservation steel plate silo provided by the invention can be used as a steel plate grain bin for storing grains for a long time.

Description

Technical field [0001] The present invention involves a gas insulation steel plate tube warehouse and its manufacturing method. Background technique [0002] Grain reserves are a major event related to the national economy and people's livelihood. For long -term grain reserve requirements, reserve warehouses can be dense, so as to meet the needs of fumigation.There are three main categories of existing granary: room -style warehouses, cement tube warehouses, and steel plate tube warehouses.The room -style warehouse gas is dense, the heat thermal insulation performance, and the food preservation effect is good.The concrete tube 仓 qi is good, the heat insulation effect is average, and the cost is high, but it can achieve mechanized production.The above two types of warehouse types can be used for long -term grain storage.The price of steel plate tube warehouses is low, the area is small, and it is easy to be mechanized. However, due to poor gas tightness, it cannot be fumigated by ...
