Internal lining bag of steel bucket

Abstract

The invention relates to a metal bucket for accommodating liquid, in particular to an internal lining bag of a steel bucket. Aiming to the problems that existing metal bucket accommodates the liquid to result in subsequent pollution hidden danger and coating stripping of the inner wall of the bucket, the internal lining bag of the steel bucket provided by the invention comprises a folding and / or winding soft bag body; a hollow sealing machine is arranged on the top of the soft bag body; the sealing machine is a connecting pipe of which the upper part and the lower part are opened; the outside diameter of the connecting pipe is matched with the inside diameter of the opening of a bucket cover; the lower end of the connecting pipe is opened and is hermetically communicated with an inner chamber of the bag body; the soft bag body is unfolded to be in a bucket shape and is matched with the steel bucket with a small opening; the connecting pipe is biased on the top surface of the unfolded barreled soft bag body and is opposite to the opening position of the bucket cover; the upper end of the connecting pipe is opened and a sealing cover is opened at the upper end of the connecting pipe; an anti-dropping locking edge nested with the opening of the bucket cover is arranged around the opening of the upper end of the connecting pipe, and when the soft bag body is plugged into the steel bucket from the opening of the bucket cover, the anti-dropping locking edge is locked with a turning edge of the opening of the bucket cover. According to the internal lining bag, coating treatment on the steel bucket is not needed, the manufacturing from pre-coating plates into the steel bucket becomes possible, the steel bucket can be repeatedly used, and the scraps are convenient to produce without pollution.

Description

technical field [0001] The invention relates to a metal drum containing liquid raw materials, in particular to a steel drum liner bag. Background technique [0002] In the existing industry, liquid raw materials are usually contained and transported in metal barrels, specifically steel barrels with small openings that meet national standards. The lids of the steel barrels with small openings are provided with standard openings for filling and exhaust ports. Industrial raw materials with different characteristics should be equipped with special steel drums, and the inner wall of the steel drums should be equipped with a coating that matches the raw materials, and these steel drums cannot be reused to hold different raw materials. The coating production process of this type of steel drums Complicated and troublesome, the output of steel drums is difficult to control, especially when there is a temporary increase in the amount, it is difficult to make a sufficient number of spe...

AI Technical Summary

Problems solved by technology

Industrial raw materials with different characteristics should be equipped with special steel drums, and the inner wall of the steel drums should be equipped with a coating that matches the raw materials, and these steel drums cannot be reused to hold different raw materials. The coating production process of this type of steel drums Complicated and troublesome, the output of steel drums is difficult to control, especially when there is a temporary increase in the amount, it is difficult to make a sufficient number of special steel drums in a short time; for some raw materials with cleanliness requirements, the existing technology and environment cannot To meet the requirements, the coating on the inner wall of the steel drum will peel off after a long time of use, which will affect the cleanliness of the raw material; the steel drum must be recycled and destroyed after use, and the steel drum that has contained special raw materials must be specially recycled and disposed of when it is scrapped. Destruction, such as improper handling of steel drums containing highly toxic industrial raw materials may cause great harm, and there is a hidden danger of environmental pollution

Although there is a bag-in-drum containing liquid separated from the steel drum, so that the steel drum can be used repeatedly, the bag-in-drum is only suitable for a steel drum with a full opening, and the steel drum with a small opening cannot use this type of bag-in-drum
