Description

In one, arrange structure

Technical field

The utility model relates to cloth liquid apparatus field, particularly relates to and in one, arranges structure.

Background technique

In the pure water preparation process of petrochemical industry, the water outlet of yin, yang bed is under the prerequisite that meets water quality requirement, simple in structure with it, invest little, output advantages of higher, is now still widely used.Filler in yin, yang bed is respectively anion exchange resin and cation exchange resin, in the time that anion exchange resin and cation exchange resin reach capacity to the absorption of ion, all needs the resin processing of regenerating.

The density of resin is generally less than water, hydrochloric acid solution or sodium hydroxide solution, model as widely used in cation bed in prior art is 001 × 7 strongly acidic styrene type cation exchange resin, like this, no matter be that resin is in the operation cycle or in the regeneration period, when liquid level in yin, yang bed is too high or resin under liquid washing away upwards at the bottom of bed, be arranged on a body in regeneration not and come under the effect of resin kinetic energy and buoyancy, be prone to middle row supervisor and be bent upwards distortion until rupture, middle row's arm and supervisor's tie point or arm are near the situation of Zhi Guanduan weakness fracture.

Model utility content

For being prone in above-mentioned prior art that middle row supervisor is bent upwards distortion until fracture, the problem that middle row's arm and supervisor's tie point or arm rupture near Zhi Guanduan weakness, the utility model provides and in one, has arranged structure.

For addressing the above problem, in the one that the utility model provides, arranging structure achieves the goal by following technological points: in one, arrange structure, comprise middle row supervisor and be fixed on middle row multiple middle row's arm of being responsible for both sides, described middle row's arm is even number, and middle row's arm is with respect to middle row supervisor's axis symmetry, the bottom of each middle row's arm is all fixedly connected with a stiffening rib that is strip, and middle row supervisor's cecum is also provided with a hoop body.

In prior art, the middle row who is arranged in yin, yang bed is cantilever beam structure, the hoop body arranging is for being connected with the offside that middle row takes over side and being fixedly connected with relative with yin, yang bed row supervisor's cecum, like this, middle row supervisor two ends in bed body are all fixed, in the middle of supervisor row and middle row's arm while being subject to active force upwards, because its two ends all suffer restraints, be conducive to prevent that middle row supervisor is bent upwards distortion until rupture or middle row takes over bending break; And on row's arm wall, be provided with multiple bar holes along its axial direction in prior art, when being used for regenerating, this hole passes through the actified solutions such as hydrochloric acid solution or sodium hydroxide, stop resin particle to leak outside, but these bar holes have weakened the intensity of middle row's arm greatly, under the buoyancy of resin and the effect of momentum, near the easy tension crack of middle row's arm lower end bar hole of middle row's main tube end, cause resin leakage, the stiffening rib arranging, for strengthening the intensity of arranging arm, is arranged the ability that arm opposing destroys in increase.

Further technological scheme is:

For ease of after middle row's arm or middle row are responsible for damage to damage parts replacing, improve the utilization rate of intact parts, also comprise the pipe flange that quantity equates with middle row's arm quantity, the connecting end of middle row's arm is provided with an adpting flange, described adpting flange is connected with a pipe flange established law is blue, one end of described pipe flange is fixedly connected on middle supervisor row, for ease of connection and the dismounting of two flanges, two flanges all adopt bolt hole span centre to arrange with respect to middle row's arm.

That takes over middle row for ease of the utility model is connected and is convenient to connection that flange connects and separates, also comprise supervisor's flange, described supervisor's flange is fixedly connected on middle row supervisor's connecting end, and the bolt hole of being responsible on flange is responsible for into span centre layout with respect to middle row.

Because the free end of therefrom arranging arm to itself and middle row supervisor's connecting end moment of flexure becomes large gradually, for saving stiffening rib material consumption, described stiffening rib is from linear the increasing of thickness value of its end to end, and the length direction of any one stiffening rib is all parallel with the axial direction of the middle row's arm being attached thereto, and one end that Rib Thickness is thicker is responsible near middle row.

For reducing stiffening rib its resistance to resin in the time that resin moves upward, optimize the utility model stressed, stiffening rib width linearity increase from the bottom to top in its short transverse described in any one, and the top of stiffening rib is the arc shaped surface of fitting with middle row's arm outer wall, further, stiffening rib lower end is set to arc shaped surface.

For simplifying hoop body structure, be convenient to the manufacture of hoop body, described hoop body comprises u tie body and is fixedly connected on respectively two journal stirrups of u tie body one side, is provided with at least one connecting bolt hole on described journal stirrup, and middle row supervisor's cecum is positioned at the U-groove bevel of u tie body.

The utlity model has following beneficial effect:

1, the utility model is simple in structure, the hoop body arranging is for being fixedly connected with row supervisor's cecum with yin, yang bed bed body, like this, middle row supervisor two ends in bed body are all fixed, when central supervisor row and middle row's arm are subject to active force upwards, because its two ends all suffer restraints, be conducive to prevent that middle row supervisor is bent upwards distortion until fracture or middle row take over bending break.

2 and on row's arm wall, be provided with multiple bar holes along its axial direction in prior art, when being used for regenerating, this hole passes through the actified solutions such as hydrochloric acid solution or sodium hydroxide, stop resin particle to leak outside, but these bar holes have weakened the intensity of middle row's arm greatly, under the buoyancy of resin and the effect of momentum, near the easy tension crack of middle row's arm lower end bar hole of middle row's main tube end, cause resin leakage, the stiffening rib arranging, for strengthening the intensity of arranging arm, is arranged the ability that arm opposing destroys in increase.
