The utility model content

The purpose of this utility model be exactly provide at the defective of above-mentioned existence a kind of W-Gum produce in the albumen retrieving arrangement of albumen and starch centrifugal station.This device adopts and comprises tank body, water-in, water outlet, material relief outlet, and described water-in is by the guide shell at pipeline feeding tank body center, and this guide shell lower end is fixed with decollator; Be provided with the annular overflow trough of forming by overflow edge, base plate and tank skin on the top of described tank body, on described overflow edge, be provided with overflow port; Be fixed with funnel between overflow edge and guide shell, the upper edge of this funnel is higher than overflow port, and the foam recovery mouth of this funnel lower end is by pipe connection foam relief outlet; Being provided with above described funnel can be around the push pedal of guide shell rotation, the external motor of this push pedal; On the tank skin of described overflow groove bottom, be provided with water outlet, be provided with the technical scheme of material relief outlet in the bottom of tank body, processing wastewater after this device will concentrate recycles, reclaim albumen wherein fully, simultaneously, also the processing to follow-up sewage has reduced difficulty, has promptly increased the income of enterprise, reduces cost again.

The technical scheme of albumen retrieving arrangement of the present utility model is: comprise tank body, water-in, water outlet, material relief outlet, described water-in is by the guide shell at pipeline feeding tank body center, and this guide shell lower end is fixed with decollator; Be provided with the annular overflow trough of forming by overflow edge, base plate and tank skin on the top of described tank body, on described overflow edge, be provided with overflow port; Be fixed with funnel between overflow edge and guide shell, the upper edge of this funnel is higher than overflow port, and the foam recovery mouth of this funnel lower end is by pipe connection foam relief outlet; Being provided with above described funnel can be around the push pedal of guide shell rotation, the external motor of this push pedal; On the tank skin of described overflow groove bottom, be provided with water outlet, be provided with the material relief outlet in the bottom of tank body.

Characteristics of the present utility model also have: be fixed with rain cap in described tank body exterior upper portion; Described decollator is conical; The bottom of described tank body is a turbination, and its maximum drift angle is less than 90 °; Described decollator is positioned at the inverted cone of tank body bottom; The upper end on described overflow edge is higher than the funnel upper edge; Described funnel is 2 or 3 or 4.

The beneficial effects of the utility model can be by obtaining above-mentioned description, sewage after this device will concentrate recycles, reclaim albumen wherein fully, being provided with above described funnel can be around the push pedal of guide shell rotation, the bubble-related issues of this processing wastewater have been solved, be provided with overflow groove, foam in the filtration process waste water fully, fully reclaimed the albumen in this processing wastewater foam, and avoid obstruction to water outlet, make and can be this reclaimer operation simple possible enterprise and bring bigger benefit.The protein content of starch wastewater reduction simultaneously is a crux, and the 1g ammonia nitrogen is equivalent to 5.6g COD, so the application of this retrieving arrangement has also been played important effect for sewage disposal, has reduced the sewage disposal load, also reduces pressure to environmental pollution.

The utilising efficiency of this retrieving arrangement is calculated, and the protein content 1.5g/l before reclaiming in the processing wastewater reclaims back protein content 0.5g/l, so reclaim 1g/l (promptly 0.1%), according to day discharge technology wastewater flow rate 1100 sides, 5600 yuan of/ton meters of albumen price, then can create direct benefit and be:

1100 * 0.1% * 5600 * 300 days=1,850,000 yuan/year
