Description
Technical field
This utility model is related to environmental conservation field of water treatment equipment, more particularly to a kind of centering ring and its rotary sealing
Head.
Background technology
Bubble-floating Method is a kind of traditional solid-liquid separation technique, solid-liquid separation to be reached, and that has individual water distribution process, shallow-layer certainly
Pneumatically supported water distribution is different with combined air flotation water distribution, the water distribution of combined air flotation be fluid from water inlet end advection to water side, stream
Body flows in a mechanism；The water distribution of shallow air-floatation be fluid from water inlet pipe vertical ascent to rotation water distributing mechanism, justified
Zhou Bushui, that is, fluid flows to movable device by fixed mechanism, so must have rotary sealing head to carry out excess fluid, turns round close
End socket plays sealing function.
Rotary sealing header structure in prior art, raw water are revolved from water inlet pipe vertical ascent to rotary sealing head into center
Swivel, then water distributing mechanism is flowed to from outlet pipe, the structure of rotary sealing head includes fixed cover, and fixed cover is connected to water inlet pipe
Together, central rotating body is arranged in the same axial line fixed cover of water inlet pipe, and fixed cover inner round wall is cylindrical with central rotating body
Asbestos packing pad, asbestos packing is used to need compacting between wall, it has hold-down ring, is compacted asbestos by the set screw on cover plate
Packing, plays leakproof effect, and the rotation of central rotating body is driven by coupling yoke, attachment pegs by swivel mount.
Into the PCT patents of invention of China, publication number：CN 102165230 B：Publication date：2014.12.10, disclose
A kind of potted component is there is provided the fluid tight sealing in flange sealing system between the flange of pipe end of adjacent pipe.Sealing system
Also use relative to flange of pipe end around and location sealing element centering ring, the centering ring between the two ends of centering ring
It is discontinuous on the circumferencial direction of centering ring, the installation site of the two ends of centering ring between flange of pipe end is to be not connected to each other
, so that centering ring can be curved to potted component therein is changed when flange of pipe end is removed.Centering ring has recessed
The inner periphery of wedge-shaped edge form, and potted component is convex with what is received in being arranged in the recessed wedge-shaped edge of centering ring
Wedge-shaped edge form wedge-shaped cross-section.Its weak point is：The patent is a grommet in fact, is exactly hold-down ring, and it is
Compacting asbestos packing, be discontinuous on its circumferencial direction, and installation site is also unconnected each other, to be convenient for changing stone
Cotton packing filling, will be connected to it and just not tear open not get off, cannot keep in repair；Both it was not connected to, and discontinuously, had been not on this device
Centering ring effect.

Embodiment 1
With reference to Fig. 1-3, the purpose of this utility model is to overcome the deficiencies in the prior art, there is provided one kind can make revolution
Seal head rotates more reliable, sealing property more effective means.As the making of existing shallow air-floatation equipment is welded with cold-working
Based on fitting, a small amount of machining part mating fastener connection is formed, and based on cold-working weldment, i.e., by hand manufacturing process be all
Operation, than larger, centre spot trueness error is big, will cause rotary body radial deflection and play, accelerating pulley for trueness error
Wear and tear outer ring.The rotation of central rotating body 4 is pulled by peripheral-traction wheel, equipment tactical diameter also than larger, end tank wobble and
Radial direction string quantity of motion is also very big, so directly affecting the running accuracy of central rotating body 4, that is to say, that the revolution of central rotating body 4
With diameter greater than the external diameter of central rotating body 4,4 cylindrical wall of central rotating body directly extrudes asbestos packing 9 so that both gaps are expanded
Greatly, cause seepage.
Key issue to be solved in the utility model be limit central rotating body X and Y-direction on two translation from
By spending.Because asbestos packing 9 is encapsulant, the frictional force of regular motion can only be received, irregular movement can cause seepage, it
Positioning can not be played a part of, based on above reason, need to increase a centering operation of the loop device to ensure central rotating body 4 can
By property.
The structure of rotary sealing head is that have fixed cover 10, and fixed cover 10 is linked together with water inlet pipe 12, centering ring
The 11 endoporus bottoms for being placed on fixed cover 10, central rotating body 4 are arranged in 12 same axial line fixed cover 10 of water inlet pipe, and are inserted in
Centering ring 11, because rotating speed it is per minute just several turns, it is desirable to not high, the optional carbon steel or stainless steel of material of centering ring 11, bring
Benefit is to change original structure, thimble 11 of just reordering, low cost, while also improving the runnability of equipment.
In the hole of the flange outer ring insertion fixed cover 10 of centering ring 11, it is excessively to coordinate between the two；Central rotating body 4
Endoporus is inserted on the small head external diameter of centering ring 11, is that gap coordinates between the two；So three is just on same axial line.
Pad asbestos packing 9 between 4 cylindrical wall of 10 inner round wall of fixed cover and central rotating body, with antiseep.Asbestos packing
Need compacting, it has hold-down ring 8, is realized by the set screw 6 on cover plate 7, the rotation of central rotating body 4 be have swivel mount 1,
Realized by coupling yoke 2, attachment pegs 3.
The rotation of central rotating body 4 is driven by 1 outward flange roller of equipment pivoted frame, and the power of roller is from reductor；Rotation
Frame 1 is linked into an integrated entity by coupling yoke 2, attachment pegs 3, central rotating body 4.
Operation principle of the present utility model is similar with traditional structure, and original equipment is increased by a centering ring without the need for transformation
11, the flange outer ring fixing card of centering ring 11 in fixed cover 10, this structure inertia.The axle insertion center rotation of centering ring 11
The endoporus of swivel 4, leaves certain gap, to ensure that central rotating body 4 can flexible rotating.Butter on 9 foam of asbestos packing, make
With the sealed faying face for being mainly lubrication, break-in packing and 4 contact-segment of central rotating body.10 inner round wall of fixed cover is wound on in
Between 4 cylindrical wall of heart rotary body, hold-down ring 8, cover plate 7 are put, asbestos packing 9 is compacted with set screw 6, while asbestos packing 9
Also it is compacted in plane on the flange circle of centering ring 11, such fixed cover 10, centering ring 11, asbestos packing 9 are just into a fixation
Body, central rotating body 4 is movable part, and the above this set assembly is also referred to as rotary sealing head.The effect of rotary sealing head is exactly solid
The fluid of section being determined excessively to active segment, flowing out from outlet pipe 5, have movable part, unreasonable structure will affect the entirety of equipment
Performance, this centering ring 11 are exactly solve it unreasonable.
Asbestos packing 9 has a suitable break-in with the cylindrical of central rotating body 4, is adjusted several times in running again
Section so that reach best fit between asbestos packing 9 and central rotating body 4.
