Example Embodiment

[0052] Example 1

[0053] A separation method, comprising the following steps:

[0054] S1: Add the material to the shredder for shredding;

[0055] S2: Cool the shredded material;

[0056] S3: Add the cooled material to the pulverizer for pulverization; the pulverizer separates the PVC and PU in the material.

[0057] In some embodiments, the leftovers of luggage are fabrics cut out during the production of luggage, belonging to polymer materials, which are mainly divided into two layers: the inner layer is a layer of PVC (polyvinyl chloride) fabric, and the outer layer is PU (polyurethane) and other fabrics; luggage scraps are treated as materials; when the materials are separated, they are first shredded by a shredder, so that large pieces of luggage scraps are shredded into small pieces;

[0058] It cools the shredded small pieces of material, so that the PVC in the material changes hard and brittle under low temperature conditions; in this way, the PVC and PU can be se...

[0066] Embodiment 2

[0067] In addition to the above method, the method further includes step S4 : removing the dust generated by the pulverizer by using the dust collector 300 .

[0068] In the process of pulverizing materials and separating PVC and PU, dust will be generated. Using the dust collector 300 to remove the dust generated by the pulverizer is conducive to protecting the environment, improving the working environment, and avoiding dust explosion.

[0069] The separation method provided by the invention makes it easier to separate PVC and PU in the material in the pulverizer by lowering the temperature of the material, thereby improving the separation efficiency.

Abstract

The invention provides a separation device and a separation method, and relates to the technical field of harmless treatment. The device comprises a shredding device, a crushing device and a refrigeration device, wherein a shredding feeding opening and a shredding discharging opening are formed in the shredding device; a crushing feeding hopper, a first discharging opening and a second dischargingopening are formed in the crushing device; the shredding discharging opening of the shredding device is connected with the crushing feeding hopper of the crushing device; in addition, the refrigeration device performs refrigeration on the materials. The separation device provided by the invention can be used for separating PVC and PU in leftovers of bags and suitcases; the separated PVC and PU can be reused, so that the leftovers of bags and suitcases can be changed from waste materials into valuable materials; the harmless treatment of the bag and suitcase leftovers can be realized; the production cost of the bags and suitcases can be reduced; the treatment problem of the leftovers for bag and suitcase production is solved.

Description

technical field [0001] The invention relates to the technical field of harmless treatment, in particular to a separation device and a separation method. Background technique [0002] The luggage industry is huge and diverse. Among them, Baigou is a well-known luggage production base in the world. It is understood that there are more than 10,000 luggage production and processing enterprises in Baigou New City, with an annual output of more than 700 million luggage, and more than 200 tons of leftovers are generated every day. A mountain of industrial waste. However, in order to save trouble, the production and processing enterprises put it into the boiler as firewood in winter, and usually pull it directly to the roadside and river bed for open-air burning, billowing black smoke and unpleasant smell. This caused serious pollution to the environment, directly affected the surrounding air quality, and occupied a lot of fertile land. [0003] Luggage waste is the fabric cut ou...
