Compared with the prior art, the present invention has the following advantages:
1, many kinds of measures is used in the transmission process of glue residue of the present invention, prevents high humidity part, highly viscous glue residue from bonding, blocking occurs
The problem of, it is provided with hammer and air bubble in caching feed bin first, solves bridge formation of the glue residue material in feed bin, blocking
The conveying of phenomenon, subsequent glue residue uses double-shaft spiral conveyer, it is therefore prevented that the bonding problem of glue residue during transportation.
2, film drier use front end for type that Wedge blade, rear end are that disk or rectangular paddle combine in the present invention
Formula can not only prevent the bonding of glue residue material, while can increase the heat exchange area contacted with material.
3, glue residue of the present invention after minimizing, is fed directly to closed compartment by the way of closed Belt Conveying
It is interior, it is therefore prevented that pollution of the dust to environment reduces the transportation cost of glue residue, together since wet part a large amount of in glue residue is evaporated
When reduce glue residue and fill occupied land area.In addition, can will be reduced since the moisture content in glue residue significantly reduces
Glue residue after change is used as the raw material of downstream other systems, can directly generate economic benefit.
4, during glue residue minimizing of the present invention, the dust content that dry tail gas is taken out of is lower, directlys adopt bag-type dust
Device is dusted, that is, can reach the discharge standard of tail gas, and exhaust treatment system is more simple.
