摘要

The vacuum belt filter useful in the processing of the cooling lubricant occurring in the preparation of metallic materials, comprises a filter container (2) having a sieve bottom (3) with support, a supply roller (4), a spray nozzle (14) arranged in a dirt chamber (6), and spray jet. A filter (5) moved through the filter container is separated into an upper dirt chamber and a lower filtrate suction chamber (7). The nozzle is dipped in a dirt liquid absorbable by the dirt chamber. The spray jet forms a flow within the dirt liquid, which is directed to a liquid surface. The vacuum belt filter useful in the processing of the cooling lubricant occurring in the preparation of metallic materials, comprises a filter container (2) having a sieve bottom (3) with support, a supply roller (4), a spray nozzle (14) arranged in a dirt chamber (6), and spray jet. A filter (5) moved through the filter container is separated into an upper dirt chamber and a lower filtrate suction chamber (7). The nozzle is dipped in a dirt liquid absorbable by the dirt chamber. The spray jet forms a flow within the dirt liquid, which is directed to a liquid surface. The nozzle leads the spray jet, which is directed upwardly to the dirt chamber obliquely opposite to the bottom and which is supplyable in a transport direction. The nozzle is adjustable to the strength of the flow of spray jets and is height adjustable to a level height of the dirt liquid in the dirt chamber. The nozzles are arranged to the longitudinal axis of filtrate suction chamber with a distance to each other in lengthwise manner. The spray nozzles are arranged to a dip frame, which carries two mutually spaced rows of spray nozzles through a joint connection tube with a fluid. The dip frame is giudably mounted in the dirt chamber for a simultaneous raising or lowering of the nozzles and mountable at a suspension. The nozzle is designed to produce the spray jets for forming fluid and/or gas flow.
