Abstract
The utility model relates to a disk concave filter plate for a rotating disc filter, which is characterized in that filter medium supports and the filter liquor discharge surfaces of both sides of the filter plate are staggered salient post-shaped surfaces or interrupted bar-shaped grooves. The utility model has the advantages that the main work surfaces can be accurately cast by metallic materials, or is stamped by engineering plastics or is processed into shaping by one-time injection molding; the manufacturing process is simple, and the productive efficiency is high. Simultaneously, the utility model has the advantages that each technological hole can be flexibly arranged, different technological requirements are satisfied, the flow resistance is small, the filtration accuracy is high, and the filtration rate is high. The utility model is a successful application of dynamic filtration.
Description
The utility model relates to a kind of filter, is in particular a kind of Spiralism type disk filter disk matrix filter.
In the prior art, filter medium on two sides of disk matrix filter supports and filtrate discharge surface design is a series of equally spaced annular concentric grooves, every groove all is drilled with aperture, the filtrate drain drilling of filter plate bottom is a slotted hole, be connected with the aperture on each ring-shaped groove, thereby form filter medium stayed surface and filtrate passing away.Exist the filtration net sectional area little, the defective that the filtrate discharge rate is little and machining amount is big, processing technology is complicated, manufacturing cost is high.
The purpose of this utility model is exactly that a kind of easy to process, disk spill filter plate with good economy is provided for the above-mentioned defective that solves prior art.Technical solution of the present utility model is as follows: a kind of disk matrix filter plate, and the filter medium that it includes the filter plate both sides supports and filtrate discharge surface; The ring packing groove of filter plate one side; The inside and outside trim ring screw hole in filter plate both sides; Filter plate assembling handle bolt hole; The cleaning solution inlet hole; The backwash liquor inlet hole; Filtrate drain drilling; Slag liquid tap.
Principal character of the present utility model is that filter medium supports and filtrate discharge surface design is the projection shape surface of interlaced arrangement or the strip groove of interruption at regular intervals.Can be by various metal material hot investment castings or by engineering plastics mold pressing or the moulding of injection moulding time processing, avoided in original technology every ring-shaped groove must bore aperture simultaneously and the filtrate passing away must bore the defective that slotted hole communicates with each aperture.Have the one-shot forming of groundwork surface, the advantage of manufacturing cost is enhanced productivity, reduced to simplified processing process
Feature of the present utility model also is: can be single face matrix filter plate, also can be designed to two-sided matrix filter plate; Cleaning solution inlet hole and filtrate drain drilling independently are set; The backwash liquor inlet hole can be set separately, also can be by filtrate drain drilling double as backwash liquor inlet hole; Can the polylith filter plate series connection reach and put forward dense effect step by step, but also each filter plate is provided with slag liquid tap separately; Installation applicable to various filter mediums such as woven wire, filter cloth, membrane materials.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the B-B profile of Fig. 1.
Fig. 4 is the another structural representation of the utility model.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises that the filter medium of filter plate both sides supports and filtrate discharge surface 7, backwash liquor inlet hole 5, backwash liquor distribution hole 6, filter medium compress the outer ring with screw 8, filter medium compress inner ring with screw 9, assemble handle compiles hole 12, filtrate drain drilling 13, cleaning solution inlet hole 14, filter plate one side with lifting bolt hole 10, slag liquid tap 11, filtrate ring packing groove 15.
As shown in Figure 4, be the another structural representation of the utility model, compared to Figure 1, the main distinction is that filter medium support and filtrate passing away are designed to the strip groove 16 of the interruption of a determining deviation.
Complex chart 1, Fig. 2, Fig. 3, Fig. 4, principal character of the present utility model is: filter medium support and filtrate passing away are designed to the strip groove 16 of projection shape surface 7 or one determining deviation of interlaced arrangement.
Feature of the present utility model also is: Fig. 1 is to Figure 4 shows that single face matrix filter plate, and the utility model also can be designed to two-sided matrix filter plate; The independent cleaning solution inlet hole 14 that is provided with, but also the double as slip adds fashionable feed slurry inlet hole step by step; Filtrate remittance case hole 12, filtrate drain drilling 13 independently are set; Backwash liquor inlet hole 5 and backwash liquor distribution hole 6 can be set separately, also can cancel 5,6, compile hole 12, tap 13 double these functions by filtrate; Can slag liquid tap 11 be set filter plates at different levels separately, also can cancel 11, carry dense back step by step by the series connection of polylith filter plate and set out cinder hole discharge slag liquid by the last level; The annular seal groove 15 of filter plate one side seals usefulness between adjacent two filter plates, can also be designed to flat seal, male and fomale(M﹠F) sealing, the sealing of chase mortise face etc.The utility model is applicable to the installation of various filter mediums such as woven wire, filter cloth, membrane material.
In sum, the utlity model has groundwork surface one-shot forming, simplification processing Technology, enhance productivity, reduce the advantage of manufacturing cost, also have simultaneously flexible setting each Fabrication hole, satisfy the different process requirement, and filtering accuracy height, the fast advantage of the rate of filtration, It is the successful Application of dynamic filtration.
