Description

Automatic packaging and conveying system suitable for bleaching powder
Technical Field
The invention belongs to the technical field of production of bleaching powder, and particularly relates to an automatic packaging and conveying system suitable for bleaching powder.
Background
The bleaching powder belongs to an inorganic bleaching agent, the main component is calcium hypochlorite, and the chemical formula is as follows: ca (OCl)2Or 3Ca (OCl)2·2Ca(OH)2White particles or powder, strong oxidizing property, corrosiveness, strong chlorine smell, easy cold water dissolution, easy explosion when mixed with combustible materials and the like. In the domestic and foreign markets, the production of the bleaching powder product mainly adopts two process routes of a sodium method and a calcium method, and the produced bleaching powder product is generally granular and powdery and also can be produced into a small amount of flakes.
Domestic sodium method production enterprises have the largest production capacity of about 5wt/y in scale, 10 production lines are provided, each production line can only achieve 5000t, produced bleaching powder products are granular, and the packaging is carried out manually. Domestic calcium method production enterprises are mainly distributed in Shanghai, Su, Hue, Xiang and the like, but most of the enterprises have smaller scale, the product specification is granular or powdery, and the packaging is also carried out manually. The major bleacher production enterprises in foreign countries are also relatively concentrated, mainly in the united states and japan, as well as in southeast asian countries. The data show that the production capacity is generally small, and the sodium method granular material is taken as the main material.
According to the packaging requirement of calcium hypochlorite, the bleaching powder product is packaged by an inner bag and an outer barrel, and the packaging specification is different from 15kg to 400 kg. Due to the diversification of the actual packaging specifications, automatic packaging does not appear in the market at present.
According to the requirement of the bleaching powder package, the bleaching powder needs a package mode of an inner bag and an outer barrel. Moreover, due to the special materials, the bagged materials cannot be immediately sealed. The conventional complete equipment for packaging the inner bag and the outer barrel is generally carried out in two stages, namely, the bagging packaging is carried out firstly, and then the barreling packaging is carried out. Because the bung hole size of outer bucket can not be very big, the open inner bag of good dress material is difficult to put into outer bucket, and has the spill the material problem.
Based on the property of the bleaching powder material, the natural aging treatment needs time and cannot be carried out by a quenching measure. Therefore, the bag mouth of the bleaching powder product is open when the bleaching powder product comes out from the front end filling unit and is in a state of waiting for aging treatment. According to investigation, enterprises in the existing market for producing the bleaching powder products have earlier construction time or smaller production capacity, and the bleaching powder products are artificially subjected to aging treatment.
The inner bag of the bleaching powder is sealed by a rope bundling mode, which is different from the conventional bag sealing modes such as folding/sewing/heat sealing and the like. The mode mainly aims at accurately positioning the bags, brings inconvenience to automatic bundling and is difficult to realize complete automatic control.
