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; Even the runner of the filter seam of lamination cylindrical structural is longer, is easily stopped up by solids; In addition, the flow direction disorder of the runner of machined filter opening filter seam, and the flow direction of stacked filter seam has only a direction promptly perpendicular to the filter element axis is restricted the distribution capability of MEDIA FLOW.
Given this, the purpose of this utility model just is to provide a kind of above-mentioned shortcoming that overcomes, with the superimposed formation filter seam of filter element, thereby improve filtering accuracy, filter efficiency, runner unobstructed, can set MEDIA FLOW to the filter of the stream of distribution medium more equably.
Laminated filter of the present utility model (referring to accompanying drawing), include a plurality of filter elements (2 that are the sheet shape that medium runner (1) is arranged of laminated construction, 14,16,21,26,30,34), with its front end of series connection filter element axial tightening part (3 is arranged, 15) filter stand (4,20,22,28,31,35), above-mentioned filter element ringwise, its side face has circumferential location division (5 32), its end face has the boss (7 18 that forms latitude filter seam (6), 19,27), become angle α between the radially bus that forms this end face and filter element axis, and 0 °＜α＜180 °, the positioning strip vertically (8 that the stage casing of above-mentioned filter stand has the peripheral location division with filter element to match, 33).
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, and filter be cone-shaped, the back taper bodily form, similar cydariform, similar dolioform respectively from two ends by sheet along filter element.
Above-mentioned filter element can be to comprise just circle and oval annular, also can be the polygon that comprises three limits, four limits, five limits etc.
The cross section in the stage casing of above-mentioned filter stand can be and has at least two radiation to divide dendritic racemosus shape, can be two, three, four, five etc., and each branch can be continuous connection along axis centre portion, or segmentation connects or point connects; Also can be and comprise circle, polygonal annular.The annular filter stand can match with the filter element of polygon annular, and polygon annular filter stand can match with the filter element of annular, makes the assembling back form medium runner at the filter element inner chamber of a plurality of series connection.
Can there be recess or projection in the circumferential location division of above-mentioned filter element, can be arranged on the interior week of filter element, also can be in the periphery of filter element.Positioning strip on the filter stand that matches with recess or projection can have fin or groove respectively; And be arranged on the periphery or the interior week of filter stand accordingly.
Above-mentioned filter element can be sleeved on the periphery of filter stand, also can be sleeved on the interior week of filter stand.
Boss on the above-mentioned filter element end face can be arranged on the one-sided end face of filter element, also can be arranged on simultaneously on the bilateral end face.The mesa shape of boss can be to comprise just circle and oval circle, also can be the polygon that comprises three limits, four limits, five limits etc.The height of boss promptly determines the width of latitude filter seam, determines according to the solid particle size that need are held back.
The axial location portion (9) of above-mentioned filter stand rearward end can be the base of ring dish type, also can be that the location is protruding.
The tightening part of above-mentioned filter stand front end can be the cover plate that is connected with filter stand with screw thread, can be bolt, also can be the microscler filter seam that has vertically, promptly stitches the awl filter element that is tapered tube of (10) through filter.
The utility model, a plurality of filter elements are overlapping, rely on the circumferential location division of filter element to match with the positioning strip of filter stand, series connection is sleeved on the filter stand, and the filter element of rearmost end is bearing in the axial location portion of filter stand, and front end is fixed whole filter elements with the tightening part.The boss of filter element makes and forms many horizontal latitude filter seams between adjacent two filter elements.
Laminated filter of the present utility model has following advantage.
One, the machining accuracy of boss height of the present utility model is easy to guarantee, the latitude filter seam precision height that therefore combines, its filtering accuracy height.
Two, the strength and stiffness of filter element are easy to guarantee, it is big that its total area of passage accounts for filter part total surface area ratio, and its filter opening rate can improve a lot, flow resistance reduction, rate of filtration height.
Three, the folded mutually formed coincidence size diametrically of filter element can be very little, particularly when constituting the cone-shaped filter, the above-mentioned size that radially overlaps can be less than 0, be that a filter element in adjacent two filter elements constitutes the filter seam with the outer girdle of girdle in it and another filter element, the size of the radial flow path of this filter seam can be minimum and unobstructed unusually, is difficult for being stopped up by solid material.
Four, the medium runner direction of the folded formed mutually filter seam of filter element, end surface shape decision by the filter element that constitutes runner, promptly be decided by to form the radially bus of this end face and the angle α between the filter element axis, thereby can obtain required MEDIA FLOW flows to, the utility model can be used as the MEDIA FLOW distributor, the MEDIA FLOW that acquisition is evenly distributed, and flow to and can set as required, particularly form inventor's invention the critical elements of boil movable bed ion-exchange process and equipment.
Five, 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.
Below, again with embodiment and comparative examples accompanying drawing, the utility model is done to set forth further.
