Abstract
The present invention provides a process and processor for reusing waste paint (i.e., a process and processor for converting waste paint into resources) which bring about efficient processing of the waste paint. In the process for reusing the waste paint, the waste paint is rolled between a pair of heated rotating drums disposed opposite to each other, to dehydrate and dry the waste paint (rough drying step); and the dehydrated and dried waste paint is ground by a rotating grinding rotor of which axial is perpendicularly arranged in a processing tank and further the dehydrated and dried waste paint is dehydrated, dried and pulverized (main drying step).
Claims14
A process for recycling a waste paint comprising:
- rolling the waste paint between a pair of heated rotating drums disposed opposite to each other for dehydrating and drying the waste paint;
- and
- grinding the dehydrated and dried waste paint by a rotating grinding rotor having an axis perpendicularly arranged in a processing tank for dehydrating, drying and pulverizing the waste paint.
A processor for recycling a waste paint comprising:
- a rolling dryer comprising a pair of heatable rotating drums disposed opposite to each other for rolling the waste paint introduced therebetween to dehydrate and dry the waste paint;
- a stirring and grinding rotor for grinding the dehydrated and dried waste paint to dehydrate, dry and pulverize the waste paint;
- and
- a processing tank provided with the grinding rotor whose axis is perpendicularly arranged in the tank.
A process for recycling a waste paint comprising:
- rolling the waste paint between a pair of heated rotating drums disposed opposite to each other for dehydrating and drying the waste paint, the drums being provided with a scraper blade in the form of a plate which is arranged on each of the rotating drums in a lateral direction of the drums;
- scratching up the dehydrated and dried waste paint by the scraper blade whose edge is in contact with a surface of each of the drums;
- and
- grinding the dehydrated and dried waste paint by a rotating grinding rotor having an axis perpendicularly arranged in a processing tank for dehydrating, drying and pulverizing the waste paint.
A process for recycling a waste paint comprising:
- heating a pair of rotating drums;
- rolling the waste paint between the pair of rotating drums to dehydrate and dry the waste paint;
- removing dehydrated and dried waste paint from the pair of rotating drums;
- delivering the dehydrated and dried waste paint removed from the pair of rotating drums to a stirring, grinding, and pulverizing device having a rotor positioned within a stirring, grinding and pulverizing processing tank;
- and
- stirring, grinding, and pulverizing the dehydrated and dried waste paint with said rotor.
A processor for recycling a waste paint comprising:
- a rolling dryer comprising a pair of heatable rotating drums disposed opposite of each other for rolling waste paint introduced therebetween to dehydrate the waste paint;
- and a rolling drum processing tank within which said rotating drums are supported;
- a stirring, grinding, and pulverizing processing tank having a rotor for stirring, grinding and pulverizing dehydrated and dried waste paint received from said rolling dryer;
- and
- a conveyor for conveying waste paint from said rolling drum processing tank to said stirring, grinding and pulverizing processing tank.
