Bulk container with metal inner container

Abstract

The invention provides a bulk container with a metal inner container. The bulk container comprises an upper piece, a middle section, a lower piece, a feeding pipe and a discharging valve, the middle section is formed by fixedly connecting the two sides of a rolled rectangular plate in a butt joint mode, the upper piece is fixedly installed at the upper end of the middle section, the lower piece is fixedly installed at the lower end of the middle section, a feeding hole is formed in the middle of the upper piece, the periphery of the lower end of the feeding pipe is fixedly connected into the feeding hole, a discharging hole is formed in the lower piece, and the discharging valve is fixedly mounted in the discharging hole. According to the bulk container with the metal inner container, the metal inner container is wide in medium loading application range and high in structural strength and can be reused more times, the number of connecting weld joints for mutual connection of the middle section, the upper piece and the lower piece is small, the structural strength is guaranteed, meanwhile, the leakage or cracking risk is reduced, the middle section, the upper piece and the lower piece are each provided with a reinforcing structure, the structural strength is improved, the transportation safety requirement is met, materials and weight are saved, and the cost and the transportation expense are reduced.

Description

technical field [0001] The invention belongs to the field of medium-sized bulk containers, in particular to a bulk container with a metal liner. Background technique [0002] The plastic IBC of the prior art has been popular in the market for many years, and is generally called a container barrel, also known as a composite intermediate bulk container. Commonly used specifications are 820L, 1000L, 1250L, commonly known as ton packaging plastic container barrels. IBC containers can be reused many times, and the advantages reflected in filling, storage and transportation can significantly reduce costs. Compared with the drum, the IBC container can save 35% of the storage space; its structure is assembled by the inner liner and the outer frame, and the inner liner is generally blow molded by a special high-density polyethylene and a large hollow molding machine. The outer frame is assembled by iron pipe, punched bottom plate and feet through screws. However, the structural st...
