Description

A kind of filter element

Technical field

The utility model is a kind of filter element, especially is the filter element that liquid ions switches such as a kind of chlorine industry salt refining equipment (chelate resin tower) and pure water, petrochemical industry are used.

Background technology

In refined brine or other fluid purification process, need the ion exchange in the liquid is come out, as: calcium ion, magnesium ion etc.When replacement process, carry out ion-exchange at the resin that device interior loads some.Because in purification and resin regeneration process, resin is very easily damaged.For preventing that resin runs off in a large number, utilize the micro gap on the filter element, stop resin particle to flow out with salt solution liquid greater than 0.18mm, cause the damage of postorder equipment.So in equipment, be covered with filter element on the filter disc, reach the purpose of decontaminating liquid.

General filter method has screen cloth type structure filter element and cylindrical structure filter element at present.Which floor net stack screen cloth type structure filter element needs, complex structure, and the cost height is difficult for the online remaining resin of cleaning screen.When using the mechanical means cleaning or changing resin, cause sieve breakage easily; And the cylindrical structure filter element, as shown in Figure 6, because its structure is cylindrical, the top is a cover plate, and liquid can only pass through from the cylindrical side slit, and resistance is bigger when fluid purification or backwash, damages its filter element easily.

Summary of the invention

The purpose of this utility model is the filter element of a kind of new shape structure of design, and it is rational in infrastructure, cleans long service life easily.

The utility model filter element mainly is made up of nut, pad, rubber blanket, communicating pipe, bottom, filter cylinder.Filter cylinder is conical, is positioned at the filter cylinder center communicating pipe, and bottom is installed on the filter cylinder bottom, and filter cylinder can be dismantled relatively with communicating pipe, fixed by the filter disc in nut, pad, rubber blanket and the filter plant.

Filter cylinder in the filter element is formed overall structure by upper and lower annulus and spacer bar, the similar oblique triangle in the cross section of spacer bar wherein, and the upper and lower of spacer bar all simultaneously is connected into one with upper and lower annulus, forms the taper filter cylinder.Slit between spacer bar and the spacer bar is greater than 0.1 and smaller or equal to 0.18mm,, stop the resin particle that surpasses this scope to pass through.

Communicating pipe top in the filter element is four cylindricalitys of hollow out, and becomes one with the bottom pipe, and its top also has the positioning step that is used for cooperating with filter cylinder installation; The bottom circular tube external wall is useful on the screw thread of fixedlying connected with filter disc in the filter plant.Fashionable by the filter cylinder slit flow when liquid, the spatial flow between four posts on communicating pipe top is to the bottom pipe.

It is injection molded that nut in the filter element, pad, communicating pipe, filter cylinder and bottom are engineering plastics.

Because filter cylinder be a taper shape, is positioned at the filter cylinder center communicating pipe, more help bearing pressure from salt solution or other liquid, resin from gravity.Reduced the liquid communication resistance simultaneously.Be covered with the slit on the tapered filter cylinder, the centre is fixed by communicating pipe, pad, nut and equipment filter disc.Filter element adopts Corrosive Materias such as acid and alkali resistance, salt to make.

Be located at communicating pipe in the filter cylinder, top has positioning step, is four cylindricalitys, is convenient to liquid and flows into.Communicating pipe, the bottom was round tubular, and outer wall has screw thread, is convenient to fix with filter disc.

The utility model has the advantages that:

1. rational in infrastructure, for dismountable, be easy to clean;

2. the liquid communication resistance is little, the filter efficiency height;

3. holding capacity is strong, long service life.

The utility model can be widely used in chlorine industry salt refining equipment (chelate resin tower) and be used for liquid ions switches such as purified water, petrochemical industry.

The specific embodiment

In conjunction with specific embodiments the designed filter element of the utility model is described further with reference to the accompanying drawings below.

Filter element as shown in Figure 1, it mainly is made up of nut 1, pad 2, rubber blanket 3, communicating pipe 4, bottom 5, filter cylinder 6.Filter cylinder 6 is conical, and communicating pipe 4 is positioned at the filter cylinder center, and bottom 5 is installed on filter cylinder 6 bottoms, and filter cylinder 6 can be dismantled relatively with communicating pipe 4, fixes with the filter disc in the filter plant by nut 1, pad 2, rubber blanket 3.Filter cylinder 6 is as Fig. 2, shown in Figure 3, form overall structure by upper and lower annulus 8,9 and spacer bar 7, the cross section of spacer bar 7 is like oblique triangle, evenly distribute, its top and bottom all simultaneously are connected into one with the upper and lower annulus 8,9 of filter cylinder, gap between every adjacent spaces bar is greater than 0.1 and smaller or equal to 0.18mm, forms the filter cylinder that profile is taper.Filter cylinder 6 outer periderm resins and liquid surround, and the liquid after being purified by ion-exchange penetrates into cartridge interior by the gap location of filter cylinder 6 peripheries, stops greater than the 0.18mm resin particle by filter cylinder 6 circumferential plays to enter inside.Be made up of several oblique triangle column shape spacer bars 7 around the filter cylinder 6 as seen in Figure 3, liquid enters from slit between the spacer bar 7.

Communicating pipe 4, its top was four column types of hollow out shown in Fig. 4,5, and the bottom is the pipe shape, and outer wall has screw thread.After liquid entered from filter cylinder 6 slits, the space of intercolumniation entered communicating pipe by communicating pipes 4 four, flows out behind the lower tubular pipe, finishes the task of decontaminating liquid.
