摘要:
The invention relates to a filter belt for separating solids and liquids during a continuous filtration process. To optimize the friction coefficient between filter belt and support table, the side of the filter belt which is in direct contact with the support table and wherein the contact extends fully over the entire belt width or on the actual support table width without the vacuum box section of the support table, is provided with micro glass spheres. The invention further relates to two methods for producing such a filter belt.

There is described is a belt cleaning blow-off device having a streamlined inner surface. In one embodiment a fluid outlet nozzle is connectable to a conduit of a blow-off device for cleaning a belt filter. The nozzle comprises a housing having an inner surface and outer surface, wherein the inner surface defines a fluid entry zone to receive fluid into the nozzle and an elongated gap for directing fluid towards the belt. The inner surface is streamlined to facilitate flow of the fluid into the gap. In a second embodiment, the blow-off device comprises a housing connectable to a fluid source and having an inner and outer surface. The housing defines a conduit for transporting the fluid within a channel, wherein the inner surface defines a surface of the channel and an elongated gap for directing the fluid towards the belt. The inner surface is streamlined and typically teardrop-shaped to facilitate flow of the fluid into the gap.

A method for manufacturing a wet master batch, includes preparing a carbon black slurry by dispersing carbon black in water, mixing a rubber latex and the carbon black slurry to cause a coagulation reaction to occur, to obtain a coagulation slurry, and subjecting the coagulation slurry to solid-liquid separation and dehydration, wherein the solid-liquid separation and dehydration comprises: filtering the coagulation slurry through a filter by gravity and depressurizing; and pressing the coagulation slurry thus filtered against an outer peripheral surface of a drum by a pressing portion, thereby pressure dehydrating the coagulation slurry. Further, a solid-liquid separation and dehydration device for manufacturing a wet master batch has a filtration filter, a filtration portion, a drum, and a pressing portion. According to the aforementioned method and device, solid-liquid separation and dehydration of a coagulation slurry containing a coagulated substance having relatively small particle can be achieved in an efficient manner.

An apparatus for performing an operation on a fluid material to separate liquid from solid matter within the fluid material The apparatus comprises a belt structure movable along a path. The belt structure comprises a belt portion adapted to be assembled into a movable tubular structure within which at least part of the operation is to be performed. The tubular structure is permeable to liquid for separation of liquid from solid matter within the fluid material. The tubular structure is continuously assembled at one end thereof and continuously disassembled at another end thereof during movement of the belt structure. The path includes a descending portion along which the assembled tubular structure passes, the descending portion being inclined whereby at least some of the solid matter within fluid material in the tubular structure is caused to move downwardly along the descending portion under the influence of gravity to facilitate cleaning of the permeable tubular structure.

A belt filter apparatus (10) for treating material to separate solid and liquid components thereof. The apparatus (10) comprises an endless belt structure (11) adapted to circulate along a path (12) incorporating guide roller structures (13) around which the belt structure (11) passes. The endless belt structure (11) comprises an elongate belt portion (15) formed of water permeable material. The belt portion (15) has two opposed longitudinal edges (17, 18). The endless belt structure (11) further comprises a zipper (19) for releasably connecting the two longitudinal edges (17, 18) together so as to form a tubular structure (21) having a flexible side wall (22). The circulating path (12) includes an assembly zone (33) at which the longitudinal edges (17, 18) of the belt portion (15) are brought together and interconnected by way of the zipper (19) to form the tubular structure (21), and a disassembly zone (35) at which the zipper (19) is released to separate the longitudinal edges (17, 18) and the tubular structure (21) subsequently opened. Means (90, 110) are provided for compressing the tubular structure (21) along a portion thereof to express liquid from the material contained in the tubular structure (21). The liquid so released can discharge from the tubular structure (21) through the water permeable belt portion (15).
摘要:
An industrial separator and dewatering plant delivers an influent to an inclined rotating filter belt for filtering out solid matter from the influent. A wash water is sprayed on the return portion of the belt to dislodge residual solid matter captured within the belt. A dewatering portion has an auger screw positioned for receiving the solid matter and the wash water. The auger screw transports the wash water and the solid matter to a compression cage where water is driven out of the solid matter by compression as it exits the plant. Alternately, the solid matter and wash water may be delivered together to a plant exit. Excess wash water is able to drain from the auger screw through a separate drain.
