Description
Technical field
The utility model relates to a kind of roll type electric salt eliminator component element, relates in particular to a kind of end cap and is provided with bayonet lock all around, the roll type electric salt eliminator component element of assembly stopping property improvement.
Background technology
In numerous areas such as electronics, electric power, biology, pharmaceutical chemical industry, high purity water or ultrapure water all there is demand widely.EDI (electric desalination) technology is the height/ultrapure water technology of preparing of an innovation occurring in recent years.It organically combines traditional electrodialytic technique and ion exchange technique, both overcome the shortcoming that electrodialysis can not advanced desalination, having remedied ion-exchange again can not non-stop run, need to consume soda acid regenerated deficiency, and these significant advantages make this technology promptly be promoted in the pure water preparation of industry-by-industry.
Electricity desalination assembly generally comprises package shell, and be arranged in the positive and negative electrode within the housing, between positive and negative electrode, and the yin, yang ion-exchange membrane of arranging alternately, and the electrode vessel, dense hydroecium and the freshwater room that are separated by the negative and positive film.Say that from structure formation electric desalination assembly generally can be divided into plate and frame structure and rolled structure.As Chinese patent CN2327675Y, CN2394705Y and U.S. Pat P6,190,528B1 discloses a kind of spiral wound EDI assembly, and it is simple in structure, comprise cylindrical housing, be located at the negative electrode of cylindrical housing inside, anode, anion and cation exchange membrane, ion exchange resin in the freshwater room, and the propping material in the dense hydroecium.Wherein, pipe core double as one electrode and dense water distribution, ion-exchange membrane and support structure material center on pipe core rolling winding layout in the shape of a spiral.The circle tube assembly two ends are provided with end cap, and end cap is fixed in pipe core, carry out Seal Design between end cap and shell and end cap and pipe core.
In existing electric desalination assembly, the structure of end cap part is divided into plastic outer cover from top to bottom, and metal strengthens gland, and plastic injection-moulded inner cap is positioned at the assembly inner core inner ring and collection (joining) the water plate of end cap bottom.Wherein end cap (metal strengthens gland and plastic injection-moulded inner cap) is locked by nut and assembly pipe core.Between plastic injection-moulded inner cap and the package shell, between assembly inner core inner ring and the package shell, designing respectively between plastic injection-moulded inner cap and the pipe core has sealed structure, and the sealing-ring mode is adopted in sealing.Constitute the sealing system of whole EDI assembly thus.When assembly used, component internal pressure will put on plastic injection-moulded inner cap and metal strengthens gland, and mainly born by metal enhancing gland.Because metal strengthens gland (stainless steel) and plastic injection-moulded inner cap is complete separated structures parts, metal strengthens gland (stainless steel) and plastic injection-moulded inner cap just is locked at assembly pipe core place, and they there is no latch-up structure at the package shell place.So when the assembly internal pressure increased, deformation can appear in the outer that metal strengthens gland (stainless steel) and plastic injection-moulded inner cap.When the component internal increased pressure, the outer part of inner cap be because the phenomenon of turning up can appear in the effect of pressure, this deformation meeting cause and plastic injection-moulded inner cap and package shell between poor sealing or inefficacy, thereby the generating assembly leakage problem.
In the assembly between the fresh water and the external world, and fresh water has only design of Sealing Structure respectively between electrode water.Because sealing is to adopt the face seal principle, therefore the surface quality at package shell internal surface trim place and the concentricity of shell is all had relatively high expectations.If package shell inner wall sealing face defectiveness, or the package shell concentricity is bad, and the sealing between sealing-ring (as the X-shaped sealing-ring) and inner walls will be bad, leak (between fresh water and utmost point water) in the assembly thereby will cause, and water water quality produced in influence; Perhaps cause assembly to leak outside in (between the fresh water and the external world), influence the normal use of assembly.
Summary of the invention
The utility model has mainly provided the roll type electric salt eliminator component element that a kind of end cap is provided with bayonet lock, its good seal rational in infrastructure, and anti-pressure ability is strong, and deformation is little, has reduced the possibility of the interior leakage of assembly appearance or the phenomenon that leaks outside; Solve existing in prior technology assembly end cap outer pressure deformation problem and assembly end cap seal problem (the interior leakage and the problem that leaks outside), and consequent electric salt eliminator component element working pressure is restricted, influences the processing property of assembly; Inner surface quality and dimension precision requirement to package shell are also higher, cause the high raising of package shell manufacturing cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of roll type electric salt eliminator component element, comprise as the pipe core of electrode one utmost point and with its concentric shell, shell is provided with another utmost point of electrode, between pipe core and shell, be provided with some anion and cation exchange membranes of alternately arranging, be separated out dense hydroecium and freshwater room by anion and cation exchange membrane, form inner core, pipe core and shell are provided with end cap, adopt web member to be connected between end cap and pipe core, be provided with sealing-ring between end cap and shell, on the shell of the outermost end of described end cap and shell joint, have several annular recessess, be provided with and the corresponding bayonet lock of groove in the end cap circumferential edge.Being arranged on around the end cap of bayonet lock, the pipe core place adopts set nut locking, the effective like this end cap problem of easy flange distortion all around that solved.
As preferably, described end cap upper surface is the plane, and end cap integral body is the circular arc of indent.The anti-pressure ability of the end cap of circular arc is more intense.
As preferably, the width of described bayonet lock is 5cm-20cm.The size of width has determined the area that bayonet lock occupies at the end cap circumferential direction, thereby makes end cap be not easy to produce flange.
As preferably, the skeleton of described end cap is to be the center with the centre hole that joins with pipe core, evenly is furnished with stiffening web radially, and the number of stiffening web is the 3-10 root.
As preferably, described sealing-ring is to be staggered by X RunddichtringO and O RunddichtringO to constitute.The X RunddichtringO has two, and between end cap and shell that one is arranged on the O RunddichtringO, between the shell and inner core inner ring that one is arranged under the O RunddichtringO, the O RunddichtringO just is arranged in the wedge gap of end cap and shell formation.After adopting the O RunddichtringO, become two seals in the sealing of fresh water with between dense water by original X RunddichtringO, X RunddichtringO and O RunddichtringO, to the isolated effect of playing " double insurance " between fresh water and the dense water, similarly, freshwater room and assembly outside also have two seals, have just guaranteed that so assembly leaks in not taking place or leaks outside.
As preferably, describedly be provided with fresh water and producing water entrance between two stiffening webs on the end cap.
Therefore, the utility model has not only improved the withstand voltage properties of rolling electricity desalination assembly, the end cap outer deformation little, thereby guaranteed its processing property, prevent effectively or alleviated the interior leakage of assembly or the phenomenon that leaks outside, also reduced manufacturing cost simultaneously.
