And desalted water charge line, the overflow plate that the bottom discharge port of dissolving tank is connected to defecator by Pulp pump and pipeline are turbid
Liquid side, the overflow plate clear liquid side of defecator are connected to the feed inlet of cyclone hydraulic separators, spinning liquid by clear liquid discharging pump and pipeline
The overflow port of separator is connected to caprolactam clear liquid pans by pipeline, and caprolactam clear liquid pans liquid outlet passes through defeated
Pump is sent to be connected to caprolactam refining system；The underflow opening of cyclone hydraulic separators is connected to the overflow plate turbid of defecator by pipeline
The overflow plate turbid side bottom of side, defecator is provided with valvular sewage pipe.
As the further improvement of technical solutions of the utility model, the feed opening of the dissolving tank is connected with spiral shell by pipeline
Conveyer is revolved, the feed inlet of screw conveyor is equipped with pulverizer.
It, can be effective after the utility model to be applied to the recycling of residue caprolactam water solution and solid caprolactam
Caprolactam in these waste materials is rationally effectively recycled, can produce preferable economic benefit.And the utility model structure
Rationally, the cost for recycling caprolactam is low for novel and setting.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
