Description
Technical field
The present invention relates to the equipment technical fields for slurry being concentrated in paper industry pulping process (dehydration), more specifically
Say it is to be related to a kind of band slurries thickener armature spindle and thickener from agitating function.
Background technique
Thickener is the important equipment in paper-making pulping industry for pulp concentration processing, and armature spindle is the core of the equipment
Component；Referring to attached drawing 1-2, the armature spindle 2 of thickener is mounted in groove body 1 in the prior art；Feed inlet 7 is provided on groove body 1
And discharge port；2 outer diameter of armature spindle is designed as 18 rib equal portions structures of near circular, is provided with the filtrate discharge of 18 absolute construction
Channel 21, one group of filter disc 3 of corresponding installation, 2 one end of armature spindle are connect each seamed edge with distributing valve in a circumferential direction, filter disc 3
Internal filtrate channel is corresponded to each other with filtrate channel corresponding on armature spindle 2, distributing valve and is connected to；The filtrate of precipitation passes through filtrate
Channel 21 is transported to outside equipment；Filter disc 3 is welded into grid-like pattern by the stainless steel wire of diameter 4mm, enters filter convenient for filtrate
In liquid channel 21, filter disc 3 be applied with 40-60 mesh polyester webs, when filter disc 3 is immersed in slurries, fibers adsorption on polyester webs,
Filtrate is entered inside filter disc 3 through the filtrate channel and distributing valve logical on armature spindle by polyester webs gap and is discharged to equipment
It is external；The concentration slurry for being adsorbed on outside filter disc 3 is peeled off from polyester webs by high pressure water and enters splicing by stripping slurry pipe 4
In slot 5, and sent by discharging conveyor screw axis 6 to discharge port.The vacuum that thickener is generated using filtrate water leg is pushed away as filtering
Power, and so that the filtering filter disc 3 on armature spindle 2 is in natural filtration, vacuum filter, the area Bao Jiang, cleaning area four by distributing valve
Working condition, successively reciprocation cycle, to have the function that pulp concentration, filtrate discharge device external from filtrate channel and refers to
Constant volume device, the slurry after being concentrated drops into discharging conveyor screw axis 6 after stripping slurry is transported to discharge port, generally dense into starching
Degree is 0.5%-1.2%, and pulp concentration is 8%-12%.
Above scheme cannot be formed with the low underflow liquid inside groove body 1 since 2 outer diameter of armature spindle is near circular structure
The stirring action of effect, when being more than 1.2% into slurry concentration, gravitational settling will occur for the fiber in low concentration slurries, therefore limit
Equipment has been made into slurry concentration.
Therefore, how to improve thickener is asking for those skilled in the art's urgent need to resolve into starching concentration to improve production efficiency
Topic.
Summary of the invention
In view of this, the present invention provides a kind of bands from the slurries thickener armature spindle of agitating function, solves existing skill
In art thickener into slurry the restricted problem of concentration.
To achieve the goals above, the present invention adopts the following technical scheme:
