Abstract
The present invention provides a nonwoven fabric recycling apparatus and a nonwoven fabric recycling method using same, the apparatus including: a mixing tank in which pulverized waste nonwoven fabric bodies and a filler are dispersed in water and mixed with each other to form a waste nonwoven fabric mixture; a fixing agent addition part for supplying a fixing agent for aggregating the pulverized waste nonwoven fabric bodies and the filler to the nonwoven fabric mixture to form a recycling raw material; and a filter tank in which the recycling raw material supplied thereto is received so that a recycling sheet is formed.
Claims9
A method of recycling a nonwoven fabric, the method comprising:
- a waste nonwoven fabric pulverizing operation of pulverizing a waste nonwoven fabric to obtain pulverized waste nonwoven fabric bodies;
- a material mixing operation of dispersing the pulverized waste nonwoven fabric bodies and a filler in water and mixing with each other to obtain a waste nonwoven fabric mixture;
- a fixing agent adding operation of supplying the fixing agent for aggregating the pulverized nonwoven fabric bodies and the filler to the waste nonwoven fabric mixture to form a recycling raw material;
- a raw material injecting operation of injecting the recycling raw material into an upper space of a filter tank, wherein the filter tank comprises a filter tank main body for providing an inner space and a filter net horizontally installed in the inner space so as to divide the inner space into the upper space and a lower space and allowing water in the recycling raw material to pass therethrough downward;
- a draining operation of draining water from the lower space to form a recycling sheet on the filter net;
- and
- after the draining operation is performed, a vacuum dehydration operation of discharging air in the lower space to dehydrate the recycling sheet.
A method of recycling a nonwoven fabric, the method comprising:
- a waste nonwoven fabric pulverizing operation of pulverizing a waste nonwoven fabric to obtain pulverized waste nonwoven fabric bodies;
- a material mixing operation of dispersing the pulverized waste nonwoven fabric bodies and a filler in water and mixing with each other to obtain a waste nonwoven fabric mixture;
- a fixing agent adding operation of supplying the fixing agent for aggregating the pulverized nonwoven fabric bodies and the filler to the waste nonwoven fabric mixture to form a recycling raw material;
- a raw material injecting operation of injecting the recycling raw material into an upper space of a filter tank, wherein the filter tank comprises a filter tank main body for providing an inner space and a filter net horizontally installed in the inner space so as to divide the inner space into the upper space and a lower space and allowing water in the recycling raw material to pass therethrough downward;
- a draining operation of draining water from the lower space to form a recycling sheet on the filter net;
- and
- a compression dehydration operation of compressing and dehydrating the recycling sheet.
