    • 专利摘要:
    Liquid/solids feed to be filtered is uniformly distributed over a filter surface by (i) initially, continuously introducing said liquid/solids feed into the feeder compartment of a compartmentalized, partitioned feed-distribution box, said feeder compartment having a volume such that no decantation results, (ii) continuing such feed as to effect an overflow of feed from said feeder compartment into a second, distribution compartment, over a partition or common wall member therebetween, via a plurality of outlet openings shaped into the top of said partition along the length thereof and being sufficiently few in number such that the rate of flow of the liquid/solids stream flowing through each opening is high, and (iii) thence uniformly cascading the entire flow of liquid/solids stream to be filtered onto suitable filter surface, advantageously after a change in the downward direction thereof.

    154) DEVICE FOR SUBMITTING AND DISTRIBUTING A FILTERED PRODUCT TO A HORIZONTAL FILTER SURFACE

    Claims (2)
    [1]
    The invention relates to the feeding of the product being filtered or the washing liquid of filters whose filtering surface is horizontal, in particular continuous vacuum filters. A device is known for supplying and distributing the product being filtered onto a horizontal filtering surface comprising a distribution chamber having two longitudinal vertical walls, two transverse vertical walls and a first overflow threshold whose height is less than the height of the vertical walls and which divides the chamber into two compartments, the first of which is bounded by the bottom and contains a nozzle for the input of the filtered product, and the second is limited by the bottom with a longitudinal opening for the output of the filtered product 1. The disadvantage of estno devices is the uneven flow in time or in the distribution that decreases filtration performance and washing efficiency. The purpose of the invention is to increase the efficiency of the filtration process. This goal is achieved in that the device for feeding and distributing the product to be filtered onto a horizontal filtering surface comprising a distribution chamber having two longitudinal vertical walls, two transverse vertical walls and a first overflow threshold whose height is less than the height of the vertical walls and which separates the chamber by two compartments, the first of which is limited to the bottom and contains a nozzle for the entrance of the product to be filtered, and the second is limited to the bottom with a longitudinal opening for the exit of the filter th product, a second compartment provided with a second discharge threshold vyprlnen nym of flexible material located below the longitudinal opening and adjacent to the filter-surface, the upper portion of the first overflow threshold is formed toothed, while the bottom of the first compartment is inclined. The teeth are made in the form of an isosceles trapezium. FIG. 1 shows a device in cross section; in fig. 2 - the same, longitudinal section. The device contains a distribution chamber 1, inside which is placed the first overflow threshold 2, the height of which is less than the height of the vertical walls and which divides the distribution chamber 1 into two divisions 3 and .4, the first of which is bounded by the bottom 5, made inclined contains a nozzle b for the inlet of the product to be filtered, and the second has a bottom 7 with a longitudinal opening 8 for the output of the product to be filtered and is equipped with a second drain threshold 9 made of a flexible material located under the longitudinal opening 8 and adjacent to the filtering surface 10. The upper part 11 of the first overflow threshold is 2 teeth, the teeth 12 of which are made in the form of isosceles tracts. The device works as follows. The product to be filtered from the first separation unit 3 through the toothed upper part 11 of the first overflow threshold 2 enters the second compartment 4, where it is dispersed by a simple or double cascade before entering the horizontal filtering surface 10, passing through the opening 8. The second effective threshold 9 serves dropping the filtered product onto the filter surface 10 below it, the filter product changes its direction, which improves its uniformity. Claim 1. A device for supplying and distributing a filtered product to a horizontal filtering surface comprising a distribution chamber having two longitudinal vertical walls, two transverse vertical walls and a first overflow threshold whose height is less than the height of vertical walls and which divides the chamber into two compartments, the first of which is limited to the bottom and contains a nozzle for the entrance of the product to be filtered, and the second is limited to the bottom with a longitudinal opening for the output of the product to be filtered, In order to increase the efficiency of the filtering process, the second compartment is equipped with a second drain threshold, made of flexible material, located under the - longitudinal hole and adjacent to the filter surface, the upper part of the first overflow threshold being gear, and the bottom of the first compartment is inclined .
