Description
The utility model relates to the Separation of Solid and Liquid element, particularly filters the filter that stitches with constituting of filter element.
Existing Separation of Solid and Liquid filter, overall structure normally, also useful lamination constitutes cylindrical structural, filter opening or filter seam adopt machining or lamination to be combined to form, machined filter opening filter seam is subjected to the restriction of machining accuracy, and the uniformity of filter opening, filter seam is not high, thereby influences filtering accuracy; Moreover because the restriction of structural strength, total area of passage of filter opening is at filter part total surface proportion, and promptly the filter opening rate is lower, and flow resistance is big, and filter efficiency is not high.That Patent Office of the People's Republic of China announces in CN94236652.2, by " laminated filter " of inventor invention, filter element between latitude filter seam make the adjacent face of adjacent filter element form the gap by the boss on the filter element end face, this gap promptly is that the latitude filter is stitched.This filter element structure is complicated, and the requirement on machining accuracy height of boss height, and its manufacturability is relatively poor, and the precision of filter seam is difficult to obtain assurance.
Given this, the purpose of this utility model just is to provide a kind of by superimposed constitute, the higher filter of filter seam precision of the better simply filter element of structure.
The purpose of this utility model is to realize with the boss of spacer shims replacement filter element end face on existing laminated filter.
Laminated filter of the present utility model (referring to accompanying drawing), include a plurality of filter elements (1,12) that are the ring piece shape that shaft orientation flowing channel (4) is arranged of laminated construction, the distance piece (8) that forms latitude filter seam is arranged between the above-mentioned adjacent filter element, the connector (9,10,13) of series connection filter element and distance piece is arranged.
The end face of above-mentioned each filter element can be the plane, also taper surface can be arranged.
Above-mentioned each filter element, the size between end face two far-ends can equate that promptly filter is cylinder shape; Also can be axially to successively decrease successively or increase progressively, or successively decrease successively or increase progressively to the centre, make filter be cone-shaped, the back taper bodily form, similar cydariform, similar dolioform respectively from two ends by sheet along filter element.
The end face of above-mentioned filter element can be to comprise just circle and oval circle, also can be the polygon that comprises three limits, four limits, five limits etc.
The end of the filter element of above-mentioned ring piece shape series connection, can be connected with vertically through filter seam (15) and be the awl filter element (14) of tapered tube.
Above-mentioned connector can be the coupling bar of helicitic texture of centre bore that runs through the distance piece of filter element and annular.
The utility model with connect distance piece between a plurality of filter elements and filter element of connector, constitutes filter, and the filter seam width of filter and precision are determined by the thickness of distance piece and precision and controlled.
Compared with the prior art laminated filter of the present utility model has following advantage.
One, the anufacturability of the utility model distance piece is good, and its thickness and precision is easier to guarantee that therefore, the precision of the filter of formation seam is higher, and its filtering accuracy is higher.
Two, adopt the distance piece structure, simplified the filter element structure significantly and replaced the filter stand of labyrinth, make the filtration device structure simplification, and manufacturability is better with the connector of rod shaped structure.
The utility model can be widely used in ion-exchanger, sand filter, carbon filter and solid-liquid separator input port thereof, delivery outlet, floss hole is held back solid material.The filter that the taper surface filter element is arranged can be used as the MEDIA FLOW distributor, determines the tapering of the conical surface as required, and the MEDIA FLOW that can obtain to be evenly distributed is specially adapted to the inventor's the movable bed ion-exchange unit that boils.
Below, again with embodiment and comparative examples accompanying drawing, the utility model is done to set forth further.
