The course of work:
The first step is filtered.Close the vomit pipe valve, closes compression air intlet tube valve is closed wash water inlet tube valve.Open the filtrate (liquid tube valve, open the feed pipe valve, the crystallization suspension flows in the container, and mother liquor separates by filter media in the crystallization suspension, flow to the mother liquor recycling can through filtrate exit pipe, crystal (filter residue) is trapped in the container, as it is more to enter container intercrystalline suspension, has surpassed mother liquor overflow pipe open height, then mother liquor can directly flow into the mother liquor recycling can from overflow pipe, treat that crystal reaches required thickness, close the feed pipe valve, stop charging.When filtrate exit pipe does not have the filtrate outflow substantially, close the filtrate (liquid tube valve.
Second step, washing.Open wash water inlet tube valve, add clear water from the bottom in container, clear water is submergence crystal from bottom to up slowly, during crystal, closes wash water inlet tube valve in the complete submergence container of clear water.Start mixer, mixer is the interior crystal of agitator treating container at a slow speed.
The 3rd step, blowing.Behind the crystal, open the vomit pipe valve in the agitator treating container, the crystal feed liquid in the container is discharged, be sent from the scheming centrifugal dehydration.Under stirring condition, feed liquid generally can not stopped up, if stop up, then opens the compressed air inlet tube valve, blow with compressed air stifled, till eliminate stopping up, closes compression air intlet tube valve again.After feed liquid has been put, close down agitator, open cover plate supernatant water inlet tube valve, add proper amount of clear water washing container Inner filter net mechanism, and the clean deposition material, washings are discharged in the lump through vomit pipe, close clear water inlet tube valve then, close the vomit pipe valve.
Behind the above end of operation, carry out next cycling.
5, invention advantage:
The utility model compared with prior art has the following advantages:
1. this device is provided with filter and agitating device in a container, and the filtration of crystallization suspension and two processes of washing of crystal are finished in same container, has simple to operately, and production capacity is big, the production efficiency height.
