Abstract
The utility model relates to a conic distribution valve core of a drum vacuum pulp washer. Both ends of a baffle plate interlayer and a wallboard interlayer are provided with connecting holes to be communicated into a whole, one end of the wallboard interlayer is communicated with a water filling pipe, and a groove is arranged at a point where the baffle plate interlayer and the wallboard interlayer need to be separated from the air. When in operation, liquid can be switched in to enter the interlayer through the water filling pipe and be ejected at the groove to achieve water-seal air exclusion. The utility model can effectively enhance the yield and the quality of paper-making pulp washing machines.
Description
Affiliated technical field
The utility model belongs to a crucial device of paper industry black liquid extraction or washing device, and drum-type vacuum washer circular cone distributes spool specifically.
Background technique
The rotor valve system of the rotary drum of existing drum-type vacuum washer and circular cone distributing valve causes one, wallboard on the stator spool, dividing plate, equally distributed many filter chambers isolation on the rotary drum circumference is distributed into the starching district, vacuum draw district and ventilation discharge zone do not allow air flows between the zone.Because rotary drum weight, diameter are all excessive, make the machining accuracy of circular cone distributing valve valve body be difficult to guarantee, the degree of adaptability of rotor valve body and stator spool is poor, only depend on the mating face of valve body spool to come mobile being difficult to of seal isolation air to realize, thereby the degree of vacuum that can't guarantee pulp washer starching district and vacuum draw district reaches technical requirements, causes slurry black liquor or water content big, and quality of product can not get guaranteeing, also can make the circular movement of slurry, the discharging difficulty with rotary drum.
Summary of the invention
Can't reach technical requirements in order to overcome circular cone distributing valve valve body machining accuracy, and cause that air flows is arranged between the pulp washer zone, a difficult problem that can not get guaranteeing with the degree of vacuum in starching district, vacuum draw district, the utility model provides a kind of new-type circular cone to distribute spool, exactly on the basis that does not change the existing equipment main body, only the internal structure of circular cone distributing valve spool is improved, thereby guaranteed that degree of vacuum reaches technical requirements.
The technical solution adopted in the utility model is: the original individual layer of stator spool " 7 " font dividing plate is changed into the double-layer clapboard, the interlayer width that have hollow interlayer be of a size of standard with original dividing plate face width, the two ends of interlayer are connected with the wallboard interlayer at original cone size two ends respectively, the interlayer joint is provided with intercommunicating pore, interlayer inside can make liquid gang up, on the wallboard that needs the air-isolation place, separator face, the groove that is interlinked to the outside in processing and the interlayer.With a steel pipe, an end links to each other with big end wall panel interlayer, and the other end is sent outside the valve, flows out identical dilution black liquor pipeline of black liquid consistency or the connection of other liquid line with this machine.When rotary drum rotates, open pipe valve, there is the liquid of certain pressure to enter interlayer by steel pipe, constantly pass through wallboard, groove on the separator face, ejection a lot of waterwall between the circular cone mating face of spool, valve body, the effect of water seal makes the air of ventilation discharge zone can't enter other two district.
The beneficial effects of the utility model are: do not change existing equipment main body rotary drum, on the basis of distributing valve valve body and spool external shape, only the internal structure of spool is improved, simple in structure, water seal is effective, starching thickness is increased considerably improve output and guarantee quality of product.

Embodiment
Accompanying drawing 1,2,3, in 4, vacuum tube (6) passes in the middle of the spool, atmospheric communicating pipe (7) passes major part wallboard interlayer (2), wallboard interlayer (2) needs the air-isolation place that groove (5) is arranged with dividing plate interlayer (3), dividing plate interlayer (3) interior two ends interlayer intercommunicating pores (4) communicate with the wallboard interlayer (2) at cone size two ends respectively, water injecting pipe (1) feeds in the wallboard interlayer (2), during work, liquid enters wallboard interlayer (2) and connects all wallboard interlayers (2) and dividing plate interlayer (3) by interlayer attachment hole (4) by water injecting pipe (1), groove (5) ejection at the air-isolation place, the effect of realization water seal.
Among Fig. 5 embodiment, rotary drum (9) is an one with valve body (8), and the drum-type vacuum washer circular cone of packing in the middle of the valve body (8) distributes spool, and water injecting pipe (1) vacuum tube (6) atmospheric communicating pipe (7) stretches out valve body (8) outside.
Claims (4)
1, a kind of drum-type vacuum washer circular cone distributes spool, it is characterized in that: wallboard interlayer (2) needs the air-isolation place that groove (5) is arranged with dividing plate interlayer (3), two ends in the dividing plate interlayer (3) have interlayer attachment hole (4) to communicate with wallboard interlayer (2), water injecting pipe (1) and wallboard interlayer (2) internal switching.
2, circular cone according to claim 1 distributes spool, it is characterized in that: wallboard interlayer (2) needs the air-isolation place to be equipped with groove (5) with dividing plate interlayer (3).
3, circular cone according to claim 1 distributes spool, it is characterized in that: water injecting pipe (1) and wallboard interlayer (2) internal communication.
4, circular cone according to claim 1 distributes spool, it is characterized in that: dividing plate interlayer (3) all is that double-layer clapboard forms.
