Description
Technical field
The invention belongs to valve means apparatus field, and in particular to a kind of rotor distributing valve applied on ceramic filter
Device.
Background technology
Ceramic filter is a kind of new, efficient, energy-conservation solid-liquid separating equipment, collects electromechanics, Automated condtrol, ultrasonic wave
The new and high technologies such as cleaning, poromerics are in one.The outstanding feature of ceramic filter is：Efficiently, save, good filtration effect, from
Dynamicization degree is high, and operating cost is low, and filtrate is limpid to be comprehensively utilized, filtration cakes torrefaction, to filter medium strong adaptability, extensive use
In industries such as coloured, chemical industry, mine, smelting, medicine, food.
Action principle of the work of ceramic filter based on capillary micropore, using extract filter medium inner chamber vacuum produce with
Outside pressure difference, the material for making to suspend in slurry vessel are adsorbed on filter medium (porous ceramic filtering plate) under suction function, Gu
Body material by the tiny micropore on filter medium because that can not be trapped within filter media surface, and liquid is because of the work of vacuum pressure difference
With and the hydrophily of filter plate pass through filter medium into arranging outside rotor distributor or utilizing, reach the mesh of separation of solid and liquid
's.Rotor fortune circles, and the course of work is divided into four regions：Pulp absorbing area, dry section, discharge zone, backwash area, iterative cycles.
The function in rotor operating one Thursday region and conversion are realized that distribution valve gear is the core of ceramic filter by distribution valve gear
One of part, directly affects the two big performance of filter plate yield and moisture of ceramic filter, in equipment running process, distributing valve
In dynamic and static sealing ring mated condition and stability directly determine the performance of distributing valve.
The distribution shaft end of dynamic seal ring and main shaft bonds together, and static sealing ring bonds together with distribution valve body, point
Correspond to pulp absorbing area, dry section, the backwash area of static sealing ring respectively with three interfaces on valve body.During work, in main shaft
Under rotation, because of vacuum and capillarity, solid material absorption, the surface for being deposited in filter plate, the micropore point that filtrate passes through filter plate
Suction zones interface and dry section interface up to distribution valve body are clipped to, and eventually enters into outer row after dehydration barrel.Backwashing water is through dividing
Backwash reverse interface malleation with valve body is cleaned into filter plate inner chamber to micropore.At present, distribute valve gear assembling,
Drainage is key issue to difficulty greatly and during use during centering, adjustment.
The content of the invention
It is an object of the invention to provide it is a kind of it is simple in construction, be easy to assemble, reliable ceramic filter centralized positioning
Bearing-type distributing valve.
To achieve the above object, present invention employs following technical scheme：A kind of ceramic filter centralized positioning bearing-type
Distributing valve, including rotor distributing shaft and the valve body of rotor distributing shaft end set, it is provided with the end face of rotor distributing shaft dynamic close
Seal, static sealing ring is provided with valve body, dynamic seal ring coordinates with the rotary seal of static sealing ring attaching type, and dynamic seal ring is with rotor
Distributing shaft rotate one week hole position sequential communication static sealing ring thereon on corresponding hole site form pulp absorbing area, dry section, discharge zone, instead
Rinsing area station, it is characterised in that：The end face center opening position of described rotor distributing shaft is provided with blind hole, blind hole and rotor point
Arranged with axle coaxial core, inner end and the blind hole of positioning screw rod form being rotatably assorted for axial limiting, and the shaft of positioning screw rod is automatic
For the middle part vestibule axis of sealing ring and static sealing ring to extending through outside valve body, the outer end of positioning screw rod, which is set, compresses spiral shell
Mother, stage clip is set on the shaft between clamp nut and valve body end face outside.
In above-mentioned technical proposal, the effect of positioning screw rod is exactly to connect and adjust the state of dynamic seal ring and static sealing ring,
And the blind hole for setting the end face center opening position of the inner end of positioning screw rod and rotor distributing shaft forms rotation and axial limiting is matched somebody with somebody
Close, it is ensured that positioning screw rod positioning, the reliability of connection and the convenience of assembling, only need to suitably screw clamp nut i.e. during regulation
Can, regulation is very convenient.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 left view.
Embodiment
As shown in figure 1, ceramic filter centralized positioning bearing-type distributing valve includes rotor distributing shaft 10 and rotor distributing shaft
The valve body 20 of 10 end sets, dynamic seal ring 30 is provided with the end face of rotor distributing shaft 10, static seal is provided with valve body 20
Circle 40, dynamic seal ring 30 coordinate with the attaching type rotary seal of static sealing ring 40, and dynamic seal ring 30 rotates one with rotor distributing shaft 10
Corresponding hole site forms pulp absorbing area, dry section, discharge zone, backwash Qu works on all hole position sequential communication static sealing rings 40 thereon
Position, the end face center opening position of described rotor distributing shaft 10 are provided with blind hole 11, blind hole 11 and the coaxial core of rotor distributing shaft 10
Arrangement, inner end and the blind hole 11 of positioning screw rod 50 form being rotatably assorted for axial limiting, the shaft automatic-sealed of positioning screw rod 50
For the middle part vestibule axis of circle 30 and static sealing ring 40 to extending through outside valve body 20, the outer end of positioning screw rod 50 sets pressure
Tight nut 60, stage clip 70 is set on the shaft between clamp nut 60 and the end face outside of valve body 20.
In order to realize that the inner end of positioning screw rod 50 coordinates with blind hole 11, and reliable axially position, concrete scheme be
Bearing 80 is provided with blind hole 11, specific annexation is as follows：The inner end of positioning screw rod 50 coordinates with the inner ring sleeve of bearing 80,
The outer ring of bearing 80 and the hole wall socket of blind hole 11 coordinate, and the inner end end of positioning screw rod 50 sets limiting stand 51, bearing 80
Opened up on the hole wall of blind hole 11 in outside internal thread with and cap 90 on external screw thread form be threadedly coupled.
In order to ensure the normal work of bearing 80, it is necessary to provide the environment suitable for work to bearing 80, i.e., suitable sealing
Environment, concrete scheme is described and the middle part of cap 90 opens up stepped hole, and smaller diameter end is located at the side of bearing 80, the end of larger diameter end
Gland 100 is set on face, and the shaft of positioning screw rod 50 sequentially passes through and leading in the middle part of the stepped hole and gland 100 at the middle part of cap 90
Hole, and sealing ring 110 is set in the region surrounded between cap 90, gland 100 and positioning screw rod 50.
Further scheme be described gland 100 by gland screw 120 with and the end face outside of cap 90 be connected.
In order to undertake the gravity of valve body 20 and associated components, described valve body 20 is arranged in distribution valve support 130, distribution
