Apparatus for effecting clarification of liquid provided with filter cleaning means
| Details |
Inventors: Yock, Lewis M.; Burdick, Jack B.;
Assignee: Globe Machine Manufacturing Company (Tacoma, WA)
Primary Examiner: Fisher; Richard V.

Apparatus for effecting clarification of liquid having particulate material entrained therewithin includes a filter screen and a filter-cleaning device disposed adjacent thereto operable for removing particulate material from the filter screen which has been deposited or accumulated thereon from a particulate-laden liquid discharged onto the filter screen. The filter-cleaning device includes a dispenser which is selectively positioned, in an automatic manner, relative to the filter screen to direct a fluid flow against the filter screen at variable locations thereon to impart movement to the retained particulate material relative to the filter screen. Additionally, the filter-cleaning device of the present invention includes a plurality of nozzles, which form the dispensing device, mounted on a carriage which is operable for carrying the dispensing device so that the nozzles will be presented over the filter screen in a selective, reciprocally shifting manner. |

DETAILED DESCRIPTION The present invention relates to the clarification of liquids and more particularly to a novel method and apparatus for effecting clarification of liquids having particulate material entrained therewithin.
The apparatus utilizes a novel means for continuously and effectively cleaning a filter employed to retain the particulate material.
In many industrial, food processing, agricultural and forest products applications, it is often necessary to clarify various liquids which have become entrained with particulate material.
Typical examples include hot water block heating systems, log yard run-off, stack scrubbers, reclamation of river or irrigation ditch water and filtration of glue spreaders or dryer wash downs.
In all of the above processes, some type of filter mechanism or catchment apparatus is provided for removing the particulate matter from a liquid stream so that the liquid may be reclaimed for subsequent reuse.
However, in all of the above processes, a significant problem remains in the continuous requirement for liquid reclamation, and also in the concomitant requirement of periodic cleaning of the mechanism or filter which retains the particulate material.
Cleaning is necessary to prevent the undesireable accumulation of particulate material not only on the surface of the filter, but also to remove that material which has become lodged in the filter's interstices.
Problems attending the clarification of water in the forest products industry may be illustrated by the following example in reference to what is referred to as a "hot water block heating process".
Such a process is used to soften the fibers in logs or "blocks", which have been substantially debarked, prior to the blocks being peeled into veneer by a veneer lathe.
It is necessary to soften the fibers to enhance peeling, and to this end, the blocks are loaded initially into steam vats where steam in the form of hot rain saturates the logs.
The water, as it falls over and saturates the blocks, becomes contaminated with foreign matter or particulate material such as bark remnants, dirt, sand, etc
