2. can't accurately measure actual production capacity
Existing feeding testing agency has mechanical type, condenser type and ultrasonic wave to visit material.When massecuite gets into basket; Centrifuge has certain rate of feeding; Wait to visit when expecting that mechanism detects material, existing part molasses are sifted out outside the basket, and because the massecuite performance inconsistency is big; The molasses that sifted out are difficult to quantize, so which kind of visits the actual production capacity that material all can't accurately be measured centrifuge.
3. rate of feeding is changeable
Existing suspended centrifuge feeding is to utilize the massecuite liquid level deadweight in the massecuite mixer-distribution to be pressed into centrifuge inside; Because it is low when high during manually-operated factor massecuite liquid level; The speed of massecuite entering centrifuge also speed differs; Influence the cloth evenness and the cycle of operation of centrifuge, and then influenced production efficiency.
Summary of the invention
The technical problem that the present invention will solve provides the suspended centrifuge feed system that a kind of rate of feeding is stable, material is evenly distributed and feeding capacity can accurately be measured.
Adopt following technical scheme for solving the problems of the technologies described above the present invention: the suspended centrifuge feed system mainly is made up of feed tank and massecuite distributor gear; One of feed tank is connected with massecuite mixer-distribution through feeding valve, and the other end is connected with the massecuite distributor gear through bleeder valve; Evenly be provided with cloth mouth on the massecuite distributor gear, perhaps evenly divide the pass cloth tube to basket towards the massecuite distribution plate.
The sugared cake distribution plate top that the massecuite distributor gear is installed on the centrifuge cover plate or centrifuge is interior.
The charging volume of feed tank and the production capacity of centrifuge are complementary.
Feed tank is provided with Charge level measurer.
Massecuite in the feed tank is promoted by compressed air or mechanical pump.
The present invention adds feed tank and massecuite distributor gear between existing massecuite mixer-distribution and centrifuge; The massecuite distributor gear concentrates symmetrically that sprayed feed has realized that cloth is even in the centrifuge basket; Avoid the state of centrifuge irregular operation, guaranteed production safety; The feed tank that volume is confirmed helps accurately to monitor actual production on the one hand, is convenient to accurately control rate of feeding on the other hand, regulates the centrifuge cycle of operation, thereby enhances productivity.
