Description
Technical field
The utility model relates to a kind of wet granulator, particularly a kind of wet granulator for production of carbon black.
Background technology
At present, known wet granulator comprise frame, cylindrical shell, several hydraulic giant, bearing, stir tooth axle and on helically arrange severally stir ratch, cylindrical shell is arranged charging aperture, discharging opening and hydraulic giant.In manufacturing technologies of carbon black; powdery carbon black enters from the charging aperture of wet granulation machine drum body; mixed by the high-speed rotation of stirring tooth with the binding agent (granulation water) with certain pressure sprayed into from hydraulic giant; hydrocarbon black powder is made to discharge rapidly the gas of surface adsorption; make surface have certain cohesive force, form tiny carbon black pellet core.The rolling under comminutor stirs the turning effort of tooth depth speed of tiny carbon black core, extruding, shearing, constantly mutually collide and increase, form particle granules, granulation process is divided into: mixing-granulation-polishing.Current known wet granulator, all adopts casing cylinder and the rotor of same diameter, when rotational speed of driving unit is fixing; same linear velocity can only be exported, linear velocity can not be changed for granulation process feature separately, and granulating rate is low; distribution of particles is wider, and qualification rate is low.Particularly for the higher soft carbon of structure and special carbon black, granulation outcome is bad.
Utility model content
The purpose of this utility model is just the above-mentioned shortcoming overcoming prior art; there is provided one can for different granulation process; export the comminutor of corresponding different linear velocity; and granulating rate is high; distribution of particles is narrower; qualification rate is high, and be particularly useful for the super-normal structure black kind higher to granulation requirement, granulation outcome is good.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of reducing barrel-type wet granulator, comprise frame, casing cylinder and stir tooth axle, stir tooth axle comprise rotating shaft and helically arrange thereon stir ratch, it is characterized in that: described casing cylinder comprises the shell ring of several different size diameter, the shell ring of different-diameter is connected successively according to diameter, shell ring after being connected is same axis, the shell ring that diameter is minimum arranges charging aperture, the shell ring of largest diameter arranges discharging opening; The described tooth axle that stirs is steppedly stir tooth axle, stirs tooth rotating shaft and is divided into several rotating shaft section according to the shell ring quantity of correspondence, and the shell ring of the corresponding same diameter of each rotating shaft section, the length of each rotating shaft section being stirred ratch matches with the diameter of corresponding shell ring.
Preferably, the quantity of described shell ring is 2-3.
Further, the shell ring of above-mentioned different-diameter is connected and fixed according to diameter is linked together by welding or flange bolt.
Further, described in stir ratch by being welded to connect in rotating shaft, arrange in the shape of a spiral, head number is more than double end or double end.
Compared with prior art; the utility model has the advantage of: the utility model provides a kind of reducing type cylindrical shell wet granulator be made up of the shell ring of different-diameter size; it stirs tooth axle is steppedly stir tooth axle; stir tooth axle rotate in cylindrical shell can realize different-diameter shell ring region in stir ratch end there is different linear velocities; therefore the utility model has multiple line speed; corresponding linear velocity can be exported for different granulation process, improve granulation quality and efficiency.The utility model structure is simply novel, reasonable in design, and granulating rate is high, and distribution of particles is narrow, and qualification rate is high, and especially for the kind of carbon black (the special product carbon black of soft carbon, part) of high structure, granulation outcome is good, and particle quality is high.Simultaneously the utility model also can change the number of fragments of shell ring and diameter than the wet granulation being applicable to other material according to material characteristic.

Detailed description of the invention
In order to clearly understand the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model is not limited in the examples below.
See Fig. 1, Fig. 2, a kind of reducing barrel-type of the utility model wet granulator, comprise frame 1, casing cylinder 3 and stir tooth axle 2, stir tooth axle 2 comprise rotating shaft 21 and helically arrange thereon stir ratch 22, described casing cylinder 3 is D1 by diameter, D2, D3(D1 < D2 < D3) D1 shell ring 31, D2 shell ring 32 and D3 shell ring 33 are connected to be fixedly connected sequentially according to diameter by flange bolt and form together, D1 shell ring 31 is arranged charging aperture 4, D3 shell ring 33 is arranged discharging opening 5, carbon black flows into the larger shell ring of diameter successively from the shell ring that diameter is less.
The described tooth axle 2 that stirs is for the stepped tooth axle that stirs, stirring ratch 22 adopts the form of welding to be fixed in rotating shaft 21, arrange in twin-feed spiral, stir the locus circle diameter that ratch 22 top formed along rotating shaft 21 axis and be respectively d1, d2, d3, and d1 < d2 < d3, also flow to direction along carbon black and arrange successively.Stir tooth rotating shaft 21 and be divided into d1 rotating shaft section 211, d2 rotating shaft section 212, d3 rotating shaft section 213 according to the shell ring quantity of correspondence, d1 rotating shaft section 211 length corresponding D1 shell ring 31 length, d2 rotating shaft section 212 length corresponding D2 shell ring 32 length, d3 rotating shaft section 213 length corresponding D3 shell ring 33 length, stir the corresponding shell ring quantity of ratch 22 and have three kinds of scale lengths, often kind of scale lengths and corresponding shell ring diameter matches.
Stir tooth axle 2 to install from the discharging opening 5 of casing cylinder 3, making the locus circle of d1, d2, d3 just in time correspond to diameter in casing cylinder 3 is three sections of shell rings of D1, D2, D3, and leaves necessary gap, is then fixed in frame 1 by casing cylinder 3.
In actual production runs, powdery carbon black and granulation water enter comminutor, under the High Rotation Speed stirring tooth axle 2, stir ratch 22 pairs of material actings.In casing cylinder D1 shell ring region, the linear velocity of stirring ratch 22 is not high, and carbon black and granulation water are uniformly mixed in this region, meets the requirement mixed; In casing cylinder D2 shell ring region, the carbon black mixed is in this closely knit granulation, and this is the effective coverage of granulation, can meet granulation requirement by stirring the higher linear velocity of ratch 22; In casing cylinder D3 shell ring region, the carbon black completing granulation needs closely knit further, and uniform particles and surface finish, now need to stir the high linear velocity of ratch 22 and just can meet the demands.
