Technical field

The invention belongs to paper making equipment technical field more particularly to a kind of drum sieves for coarse sizing system.

Background technique

Traditional drum sieve is coarseer for shape in continuous disperse system (highly concentrated size degradation or low dense size degradation) removing waste paper Light impurity.

If the utility model of notification number CN205711536U discloses a kind of drum sieve, drip irrigation device includes shell Body, the circular drum for being set to enclosure interior, roller are equipped with sieve pore, and roller is equipped with the engine for driving it to rotate Structure, is equipped with slurry reclaiming chamber between roller and shell, the lower part of shell is equipped with the thick liquid discharge mouth being connected to slurry reclaiming chamber, thick liquid discharge mouth Lower section be equipped with slurry recovery pond, by sealing plate sealing, the other end is slag notch, the center of sealing plate for one end of roller It is connected with inlet pipe, the inner wall of rotary drum is equipped with the baffle being threaded through for slurry, and baffle is equipped with even universal hole.Baffle Setting extends the path that slurry passes through roller, and the setting for connecting universal hole on baffle can speed up the impurity discharge roller of weight, Improve efficiency.

As the utility model of notification number CN202730528U is related to a kind of drum sieve comprising motor, shell and screen cylinder, electricity Machine and screen cylinder are drivingly connected, and screen cylinder is set to the inside of shell, and water slurry reclaiming chamber is equipped between screen cylinder and shell, under shell Portion is equipped with the thick liquid discharge mouth being connected to water slurry reclaiming chamber；The inside of screen cylinder is equipped with flight, and flight is in around the central axes of screen cylinder Helical form setting.Compared with prior art, it is equipped with spiral helicine helical blade extension slurry in screen cylinder of the invention and passes through cylinder The time of sieve separates the impurity of slurry preferably with fiber, and screening effect is good.

As the utility model of notification number CN208486121U discloses a kind of closed drum sieve, including rack and installation The lower section of screen drum on the rack, screen drum is equipped with stock tank, and stock tank is fixedly connected with rack, and the top of screen drum is equipped with combination shield, Frame upper end is equipped with sink, and the bottom of sink is equipped with water outlet, and water outlet is connected with stock tank, and spray tube is equipped in sink.It can It is effectively prevent screen drum top position shower water sputtering rebound and the leakage of part size, avoids pollution environment.

Patent disclosed above is the drum sieve for low dense or highly concentrated continuous disperse system, the circle of low dense continuous broken system Shaft screen is for handling the slurry after D type pulper size degradation, and the tail slurry after impurity separator is again into drum sieve；It is highly concentrated continuous The cylinder of size degradation system is the slurry after handling high-concentration pulper size degradation, again into drum sieve after coarse classifier.Due to continuous Size degradation system is located at waste paper pulp-making process flow most initial position, and slurry impurity is relatively more, and volume is bigger, so general select Be 10mm or so hole sizer, the light impurity volume screened is also bigger.

And treated that good slurry will also be using the screening of coarse sizing system, to realize to light in tail slurry for continuous disperse system Impurity is thoroughly separated.Traditional pulping process is the separation for selecting scalping tailings sieve to carry out light impurity in tail slurry, effect Fruit is bad.And the slurry due to entering coarse sizing system and the slurry form of continuous disperse system are different, the inside impurity All kinds of, volume size it is also different, existing drum sieve be not applied in coarse sizing system light impurity in tail slurry thoroughly point From causing the defect that handling capacity is small, fiber loss rate is high.
