Description
Technical field
The utility model relates to a kind of rotor and applies its D type pulper, more particularly, relates to the rotor that a kind of paper industry waste paper pulping workshop section adopts and the D type pulper applying it.
Background technology
Along with the continuous increase of paper industry production capacity, wastepaper as raw material use amount is increasing, one of waste paper pulping workshop section operation becoming most critical, is also the place that in production line, energy consumption is larger.
A kind of possible selection of waste paper pulping operation adopts rotary drum pulping machine, and this is the visual plant of waste paper pulp-making.Existing rotary drum pulping machine generally all includes the bulging body that can carry out rotating, and the raw materials such as waste paper are carried out size degradation by drum body in the process of rotating, usually containing the impurity such as cloth, iron wire inside raw material.Due to the complicated component contained in raw material, this existing rotary drum pulping machine is usually not competent, and the performance of its pulping ability cannot mate its importance in waste paper pulp-making technique.
Applicant Andritz (China) Co., Ltd. is on October 23rd, 2014 the Chinese utility model patent CN201410570915.6 being called " rotary drum pulping machine " applied for and the Chinese utility model patent CN201420618673.9 being called " rotary drum pulping machine " equally, disclose a kind of rotary drum pulping machine, comprise barrel tumbler body and feed hopper, described barrel tumbler body is provided with charging aperture, described feed hopper is arranged on described charging aperture place, and the feeding-passage of feed hopper leads to described charging aperture, realize being tightly connected by labyrinth seal structure between described barrel tumbler body and described feed hopper.By arranging labyrinth seal structure, the equipment operating efficiency of this rotary drum pulping machine can be improved preferably, and can realize downtime reducing.
A kind of rotary drum pulping machine is disclosed in the Chinese utility model patent CN201320214669.1 applied for by applicant Andritz (China) Co., Ltd. equally on April 24th, 2013, comprise the bulging body that can carry out rotating, drum body is provided with charging aperture and discharging opening, drum body inwall is fixedly connected with and organizes knife plate more, this many group knife plate is arranged along the axially spaced-apart of described bulging body, and the knife plate belonging to same group is arranged along the same circumferential of described bulging body.This rotary drum pulping machine can prevent the formation of the twisted rope that length is longer, is conducive to the size degradation efficiency improving bulging body, and then improves the production efficiency of rotary drum pulping machine self.
Technology disclosed in above patent document is mainly to the lifting of the sealing property of rotary drum pulping machine and the ability to the formation of the twisted rope preventing length longer, can not fundamentally increase and improve the performance of rotary drum pulping machine, be helpless to it and solve the right complexity of waste paper pulp-making technical face and important problem.
In production practices, generally all use D type pulper to carry out the process of waste paper pulping now, this pulper relies on the shear action of rotor and the hydraulic action of current that wastepaper as raw material dissociation is isolated useful fiber and coarse impurities.So far, D type pulper is the preferred unit of size degradation wastepaper as raw material, and this pulper is widely used in production practices.
Existing D type pulper cell body is designed to D shape, comprise the parts such as cylindrical shell, arc, cone, bottom support, D type structure object is the baffling effect increasing current, and cone bottom is with deflection plate, make wastepaper as raw material easier close to rotor, improve size degradation efficiency; This pulp kneader rotor adopts Fu Kesi form, and comprise rotor block, blade, rotor block is that casting forms, and blade is that wear-resisting alloy steel is welded on rotor block, increases ABRASION RESISTANCE, improves rotor service life.
A kind of D type pulper is disclosed in Chinese patent CN201020583917.6, this kind of D type pulper, the rotor center comprising D type cell body, transmission device and be arranged in D type cell body, the sidewall of described D type cell body inside is provided with flow-disturbing fin, the existence of flow-disturbing fin adds the chance that slurry changes traffic direction, make slurry more easily arrive rotor center place and by size degradation, shorten beating time, improve the efficiency of pulper.
But, because wastepaper as raw material dopant species is various, dregginess is large, although D type pulper size degradation efficiency of the prior art is higher, but also there is obvious shortcoming, due to the hydraulic action of this pulper and the shear action of rotor strong, a large amount of impurity in wastepaper as raw material are by size degradation refinement, more loads are brought to follow-up screening slag removal equipment, increase the weight of the wearing and tearing of follow-up equipment, have impact on the performance of its production capacity, simultaneously, this D type pulp kneader rotor and sieve plate are too strong due to shear force, also cause it to cross quick-wearing.Because machine utilization is comparatively large, corresponding energy resource consumption is also large.
A kind of energy-efficient D type pulper is disclosed in Chinese patent CN201320868053.6, D type cell body comprises sidepiece arc plate that is dull and stereotyped and that be connected with sidepiece flat board, bottom sidepiece flat board and arc plate, base plate is set, above base plate, impeller is set, wheel bottom is provided with sieve plate, impeller connection rotating shaft, between rotating shaft and base plate, sealing device is set, the arc of indent is set inside sidepiece flat board, intilted side plate is provided with between arc plate and base plate middle part, side plate bottom arranges slag-drip opening, pulp dish is set between impeller and base plate, pulp tray bottom arranges discharging opening, base plate outside pulp dish is arranged heavy slag deflector.This device is provided with many cone cylinder transition structures, optimizes the flow path of slurry, decreases unnecessary energy consumption.Sediment district is set in bottom simultaneously, heavy seeds can be discharged fast, decrease the wearing and tearing to pulper impeller and sieve plate, it also avoid the excessive size degradation of impurity simultaneously, enter follow-up flow process, alleviate the infringement that follow-up equipment is caused.
The technology that the document discloses is attempted by being discharged by the heavy seeds after pulping with speed as quickly as possible, to reach the object reduced wear with excessive size degradation, but it is conceived to the heavy seeds falling into sediment district, bottom, in the overall process of waste paper pulping, the problem of excessive size degradation and wearing and tearing all exists always, and it is not effectively solved.
