The superficial layer regenerating resin bed comprises a regenerating resin bed cylinder flange and an end cover plate arranged on the regenerating resin bed cylinder flange; the regenerating resin bed cylinder flange is fixed to the end cover plate through a fastening bolt; the regenerating resin bed cylinder flange is provided with a wedged groove; the wedged groove is internally provided with a sealing ring; a bulge is arranged below the end cover plate; and the regenerating resin bed cylinder flange is provided with a groove matched with the bulge. The resin column end cover sealing structure disclosed by the utility model is reasonable in structure and strict in technology; the sealed state of an end part of the resin bed is changed so that the sealing efficiency of an end cover of a superficial layer bed is greatly improved; and the resin column end cover sealing structure is reliably sealed and is simple to mount and convenient to machine; and the cost is reduced.
Description
Technical field
The utility model relates to a kind of resin column end cap seal structure that is used in efficient shallow-layer resin bed, is specially adapted to efficient shallow-layer ion exchange regenerant resin bed.
Background technology
In ion-exchange unit, the regenerating resin bed is a core key part, and it is responsible for various zwitterion or the salts that need removal in the adsorbing and removing feed liquid.Therefore, the quality of regenerating resin bed design is directly connected to the performance quality of ion-exchange unit.
Shallow-layer bed regenerating resin device is usually designed to cylindrical shape in shape, and the planar ends cover plate for sealing is adopted in top and bottom, and fluid is filled with particulate resin material by the end casing turnover regenerating resin bed apparatus of top and bottom in the cylindrical shell of regenerating resin bed.In order to prevent that resin from overflowing and the even distribution of fluid, can be at resin bed two ends design distribution grid and retardance gauze.The distribution grid of existing shallow-layer resin bed and gauze design are the modes of making gauze on a kind of rubber ring, as shown in Figure 3.Gauze 12 is made on rubber ring 13, and the retardance resin is overflowed.Its end cap seal is formed flat seal by shell flange 1, end casing 4, rubber washer 13, polypropylene distribution grid, and is fastening by bolt of cover, prevents that an interior liquid is to external leakage.But, have relatively high expectations for the flat seal of forming by rubber ring because the resin bed barrel diameter is big.In the actual use, because the influence of machining accuracy, material behavior and skilled operation degree causes sealing surface not tight through regular meeting, liquid causes resin bed parking maintenance, equipment corrosion, problems such as operating efficiency reduction via the fault that the rubber sealing face leaks in the bed.
In addition, because the resin bed device after every operation a period of time, need be taken upper end cover apart, carry out the work that resin fill or resin are changed.See before and state, because high order net sews up and be fixed on the peripheral sealed rubber packing ring, repeated disassembled and assembled and compressing can cause the distortion song of rubber washer to stick up, and the damage of high order net, causes adverse consequences such as a body leakage, resin escape.
Summary of the invention
Inherent shortcoming during the utility model has in the prior art that end casing sealing is actual and uses at efficient shallow-layer regenerating resin bed, processing difficulties, operation requires high shortcoming, and a kind of shallow-layer regenerating resin bed end sealing means of simple in structure, good sealing effect is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Shallow-layer regenerating resin bed, comprise regenerating resin bed shell flange, be arranged on the end casing on the regenerating resin bed shell flange, regenerating resin bed shell flange and end casing are fixed by fastening bolt, described regenerating resin bed shell flange is provided with wedge-shaped slot, sealing ring is set in the wedge-shaped slot, described end casing below is provided with projection, regenerating resin bed shell flange is provided with the groove that agrees with mutually with projection, make end cap fix at the shell flange relative position, help operation, and improve the stability of sealing.
As preferably, the cross sectional shape of described sealing ring is the O type.
As preferably, shallow-layer bed regenerating resin device also comprises guiding device, and guiding device is placed on the end of resin column, has stria on the periphery of described guiding device outer wall, O-ring seal is set in the stria, and the retardance resin particle is escaped from the slit between gauze guiding subassembly and resin bed cylindrical shell.
Wedge shape annular groove on the resin bed shell flange, by the fastening effect of bolt of cover, end cap tightly suppresses the O RunddichtringO in the groove, forms primary sealing area in wedge-shaped slot.The effect of primary seal is to stop resin bed inner high voltage liquid to release outside bed, and it is higher to bear pressure.The auxiliary seal face is made up of a cannelure on an O RunddichtringO and the gauze guiding subassembly, and the effect of auxiliary seal is that the retardance resin is overflowed to the end pipeline in resin bed, and pressure reduction is less.
The utility model has significant technique effect owing to adopted above technical scheme:
The utility model is rational in infrastructure, and technology is tight, has changed the sealing state of resin bed end, makes the leakage efficiency large increase of shallow-layer bed end cap, and sealing is reliable, installs simply, easy to process, and cost reduces.In addition, since secondary surface be and cylindrical shell between axially the sealing, so the dismounting of gauze baffle assembly is very easy easily, the operating efficiency that makes resin bed change resin improves greatly, help integral body improved Di utilization rate and efficient and general technical performance.

The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1 to accompanying drawing 2:
Shallow-layer regenerating resin bed, extremely shown in Figure 2 as Fig. 1, comprise regenerating resin bed shell flange 1, be arranged on the end casing 2 on the regenerating resin bed shell flange 1, regenerating resin bed shell flange 1 and end casing 2 are fixed by fastening bolt, described regenerating resin bed shell flange 1 is provided with wedge-shaped slot 3, O RunddichtringO 4 is set in the wedge-shaped slot 3, and described end casing 2 belows are provided with projection 5, and regenerating resin bed shell flange 1 is provided with and projection 5 grooves that agree with mutually 6.
This device also comprises guiding device 7, and guiding device 7 is placed on the end of resin column 8, has stria 9 on the periphery of described guiding device 7 outer walls, and O-ring seal 10 is set in the stria 9.
The utility model is rational in infrastructure, and technology is tight, has changed the sealing state of resin bed end, makes the leakage efficiency large increase of shallow-layer bed end cap, and sealing is reliable, installs simply, easy to process, and cost reduces.In addition, since secondary surface be and cylindrical shell between axially the sealing, so the dismounting of gauze baffle assembly is very easy easily, the operating efficiency that makes resin bed change resin improves greatly, help improving Di overall utilization rate, efficient and general technical performance.Simultaneously, owing to reduced the probability of damage of gauze baffle assembly, make maintenance cost reduce.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
