Equipped with groove 1034, sealing ring is installed in groove 1034, the water ring regulating mechanism on withstanding part 1033 and annular slab 37 is installed
It takes small―gap suture to cooperate between through-hole, plays guiding role；Above-mentioned clamping part is six side of standard, five sides or non-standard clamps knot
Structure etc., preferably six sides are used as wrench position rotation and adjust stud 103, the head of fastening bolt 101 and clamping part
Gasket 102 is equipped between 1031,102 inner ring of gasket hugs on 101 outer diameter of fastening bolt, and fits in bolt head bottom
Face, gasket 102 are chosen as rectangular rubber mat；Above-mentioned adjusting stud 103 is mounted in the installation through-hole (not shown) of annular slab 37,
Fastening bolt 101 passes through connecting hole 932 coaxial with installation through-hole on the central through hole and connecting flange 93 for adjust stud 103
(internal thread hole) is threadedly coupled, and the length of fit by adjusting the internal screw thread in threaded portion 1032 and installation through-hole, which is realized, pushes up
Hold the height that portion 1033 pushes water ring cylinder 91, the upper surface of sealed groove 1034 is away from adjusting the distance of 103 upper surface of stud not
Less than dilution 9 maximal regulated distance 5mm~10mm of water ring.
Between the upper surface of dilution water ring cylinder 91 and the lower end surface of rotor outer barrel 55 gap can according to slurry seed type and
The difference of concentration is adjusted using water ring regulating mechanism 10, and adjustable range is 1mm~5mm.A period of time is run in equipment
Afterwards, corrosion function is constantly washed away due to slurry, the lower end surface for diluting 9 upper surface of water ring and rotor outer barrel 55 will appear mill
At this moment damage can be adjusted dilution water ring 9, detailed process is as follows: equipment downtime simultaneously empties, pine so that gap be caused to become larger
Open fastening bolt 101 and locking nut 104, using spanner rotate (forward or reverse) clamping part 1031, make threaded portion 1032 with
Screw thread pair (internal thread hole) in installation through-hole on annular slab 37 is threadedly coupled, and then makes withstanding part 1033 along height side
It moves up and down, due to the upper surface support dilution water ring 9 of withstanding part 1033, dilution water ring 9 on withstanding part 1033 also with moving down
It is dynamic, and then realize that the size (gap between dilution water ring cylinder and rotor outer barrel) of dilution tunnel is adjustable, in the process,
The connection ring 931 of 9 inside of dilution water ring and the inner wall of annular slab 37 remain sealed connection.
The screw pitch adjusted on stud 103 is certain, is determined on dilution water ring cylinder 91 by measuring the method for reach
Gap between 55 lower end surface of end face and rotor outer barrel.When gap reaches designated value, tightening retaining nuts 104 are fixed to adjust
Stud 103 is saved, the fastening bolt 101 with end face seal pad 102 is passed through and adjusts 103 central through hole of stud, and is uniformly locked,
To fixed dilution water ring 9.It dilutes there are two at sealing in water ring regulating mechanism 10, gasket 102 is used as sealing and adjusts stud
103 central through hole；Radial direction seal ring 105 is used as the circle for the small―gap suture cooperation that sealing is adjusted between stud 103 and annular slab 37
Post holes.The material sealed at above-mentioned two is nitrile rubber or fluorubber, and compression ratio with higher.
Working principle of the invention is as follows: slurry is by the slurry intake channel with pressure into lower case 33 of inlet pipe 13, spiral liter
Streaming moves up in upper housing 32 notch 57, pulp flow channel and the upper isolating ring plate on the successively lower isolating ring plate 53 through rotor 5
Notch 57 on 51, with the concentration channels entered between 5 outer surface of rotor and screen cylinder 6 by 5 upper space of rotor.Slurry to
During upper movement, heavy seeds therein are deposited on the bottom of lower case 33 due to the effect of gravity, in addition, due to inertia
Effect move in a circle, and collected by weight slag pipe 14, meanwhile, wash tub pipe provides flushing water, so that heavy seeds are quickly from weight
Lower case 33 is discharged in slag pipe 14；Into the slurry of concentration channels, during rotor 5 circumferentially rotates, it is bubbled as table in screen cylinder 6
Face provides the periodic positive and negative cleaning pulse of press-down type, is ensuring that screen cylinder 6 is nonclogging simultaneously, so that filtrate passes through screen cylinder 6 simultaneously
It is discharged by filtrate pipe 7, and the slurry after being concentrated then is moved downward and is discharged by grout outlet 8.
Due to the enrichment of slurry and the inspissation of equipment, for slurry during moving downward, filtrate can pass through micropore
The micropore of plate 62, discharge screen cylinder 6 enter filtrate pipe 7, this results in slurry more to move downward, and concentration is higher, to easily cause
Blocking at grout outlet 8.For this purpose, the present invention is special to be provided with dilution water ring 9 and dilution water ring regulating mechanism 10, asked to solve this
Topic, i.e., will adjust certain interval between the upper surface of dilution water ring cylinder 91 and the lower end surface of rotor outer barrel 55, slurry into
While slurry, the highly enriched area of equipment can be entered by this gap (dilution tunnel) into a part of low underflow of slurry side, thus right
High underflow carries out certain dilution.
It is that a kind of upflow pressure thickener provided by the present invention is described in detail above, it is used herein
