Description

The present invention relates to a pocket coil processing apparatus.

Nowadays, the recycling of waste is attracting social attention. Above all, there is a high social demand for separating useful substances from wastes in which metals and resins are mixed.

In particular, the above waste is aimed at building a recycling-oriented society in which the thermoplastic resin material and the pocket coil waste in which the metal material is used are separated into the resin and the metal, and the separated materials are reused respectively. There is a high demand for equipment that can process efficiently and preferably continuously.

Here, the mattress includes natural materials such as metal, resin, and cellulose. Above all, the processing of the mattress including the pocket coil in which the coil spring is individually wrapped in the package formed of the resin non-woven fabric is laborious.

Therefore, there has been a demand for a device for separating useful materials such as metals without causing an adverse effect on the environment as much as possible when disposing of a discarded mattress and without man-hours.

In this regard, a dismantling device including a storage space for accommodating a pocket coil and a heating means for heating the package of the pocket coil to a temperature at which it melts has been proposed (for example, Patent Document 1).

However, according to this conventional technique, a large amount of energy is required because the heat treatment is performed in order to detoxify the harmful exhaust gas generated when the pocket coil is processed.

Further, in order to save this energy, a waste heat treatment apparatus including a wet scrubber that sprays water on the exhaust and further filters out harmful substances by a filter has been proposed (for example, Patent Document 2).

However, this prior art requires the use of a dedicated material for the filter, which further becomes waste after use.
