Abstract

A kind of mixing machinery, it is characterized in that there are two revolving bodies for making synchronous backward rotation rotating around trunnion axis in a fixed container, and the equably forward-reverse spiral blade of interconnected Unequal distance on revolving body.Material in mixing can long period in indwelling machine, and be stirred extruding through repeatedly coming and going and rub mill with the hands, improve mixed performance and quality.The present invention has that batch mixing is uniform, and former secondary material ash content undulate quantity error amount is less than ± 2%, and production efficiency is high, rational in infrastructure, dependable performance, and power consumption is low, noise is small, the features such as being easy to maintenance, and investment of production is less than like product in the prior art.

Description

Screw-continuum mixer with double shaft
Technical field
The present invention relates to a kind of hybrid solid and the machinery of liquid, particularly has two difference in a fixed container The helical-blade agitator rotated around trunnion axis.
Background technology
At present, for hybrid solid powder and the mixer of liquid, particularly it is used for processing mixed coal powder, clay and water Agitator, typically all incidentally it is stirred using squirrel-cage crusher, this machinery production is less efficient, and energy loss is larger. During coal briquette for civillan use is processed, raw material and the secondary mixed uniformity coefficient of material either volatile matter, ash content or moisture Error amount amplitude is all bigger, and calculating error amount in production process per hour with ash content reaches ± 5%, therefore product quality is in not Stable state.The shaping that the twin shaft paddle formula batch mixer that the seventies use is used for coal briquette for civillan use mixes, and achieves certain Effect, the ash content undulate quantity error amount of product can drop to ± 4% when optimal, a kind of continuous mixer that Usm Corporation of the U.S. provides, It has two parallel chambers being close together, and is respectively provided with rotatable elongated rotor.Spiral helicine feeding part leads to entrance, turns First mixed zone of son is respectively equipped with blade, for mixture initial compression, there is the blade of greater number the second mixed zone, strengthens To the high shear force immixture of paste mixture, to improve the dispersiveness of raw material.Although such a machinery can make the mixing of material Improved, reduce mixed air, but in the central area of two rotors, i.e. the join domain mixed effects of two parallel chambers compared with Difference, yield are very low(567.5 kilograms per hour), and it is complicated, manufacturing cost is high.
The content of the invention
The purpose of the present invention is the existing twin shaft paddle formula mixer of transformation, and particularly the twin shaft paddle of mixer is subject to Improve, to improve compounding effect, reduce energy consumption, reduce product-specific investments cost, make after mixing under material ash content undulate quantity error amount Drop to less than ± 2%.
Its purpose real in the following manner of the invention:There are two parallel to be rotated around trunnion axis in a fixed container Left and right revolving body, have the configuration of forward-reverse spiral blade stagger on each revolving body respectively.When mixer is run, two revolving bodies lead to Over-driving device makees synchronous backward rotation, and material reaches revolving body feeding area, the transport screw through two revolving bodies by charging aperture The Mixed Zone being made up of forward-reverse spiral blade is sent to after blade tentatively stirring.Material advanced in the twisting of revolving body Mixed Zone Cheng Zhong, turning over before and after being made by forward-reverse spiral blade above and below axially is rubbed with the hands and Strong shear mixes, so as to obtain preferable mixed effect.
Due to the interconnected forward-reverse spiral blade on two revolving bodies of mixer, material is set to be stayed in Mixed Zone Longer time is put, is stirred extruding stranding mill through repeatedly coming and going, not only former secondary material permeates uniform, and adds and be stirred " waxy " of material afterwards is obvious to improving product quality effect.It is of the invention to have batch mixing is uniform, original is secondary to expect ash content undulate quantity error Value is less than ± 2%, and production efficiency is high, rational in infrastructure, dependable performance, and power consumption is relatively low, and running noise is low and is easy to maintaining The features such as.
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is front view of the present invention.
Fig. 2 is A-A profiles in front view of the present invention.
Fig. 3 is B-B profiles in front view of the present invention.
Fig. 4 is revolving body helical blade configuration schematic diagram in left and right of the present invention.
Sequence number 1 represents motor, 2 decelerators, 3 end-float couplings, 4 gear pairs, 5 bearings, 6 left revolving bodies, 7 in accompanying drawing Right-hand rotation body, 8 casings, 9 bases, 10 charging apertures, 11 discharging openings, 12 right-handed screw blades, 13 backpitch blades, 14 left revolving body rotations Turn direction, 15 right-hand rotation body direction of rotation, 16 feeding areas, 17 Mixed Zones, 18 discharging regions.
The agitating device of mixer is formed by being placed in two left and right revolving bodies 6,7 rotated around trunnion axis in casing 8.Return Turn as cylinder, be divided into feeding area 16, Mixed Zone 17, discharging region 18 along horizontal axis.In each of each revolving body The screw diameter of all interconnected the Unequal distance of non-engagement is 500 millimeters on individual region, helical pitch is 212 millimeters, helical angle is 80 ° 17 ' of forward-reverse spiral blade 12,13, its spiral camber is right helicoid.Referring to the drawings 4, took the vertical line in revolving body axle center Intersecting revolving body outer lower face surface is a little 0 ° and 360 ° of the anglec of rotation of revolution external surface, then positive and negative spiral shell on left and right revolving body 6,7 The configuring condition of vane piece 12,13 is as follows:(Right-handed screw blade wherein " just " is represented, negation represents backpitch blade).
When mixer works, raw material and secondary material pass through the feeding area 16 that charging aperture 10 reaches left and right revolving body 6,7, by right-handed screw Material is tentatively stirred backward Mixed Zone 17 and promoted by blade 12, the positive and negative spiral shell of equally distributed Unequal distance in blended region 17 Vane piece 12,13 is made rotator shaft and stirred to twisting of stirring front and rear up and down, and strong by helical blade edge and cabinet wall work Shear-mixed, obtain and discharging opening 10 is pushed into by the forward-reverse spiral blade for the region Unequal distance that discharges after comparatively ideal mixing.Through testing, The mixed process of this form can be such that material mixing time in machine is up to 4 minutes, the material stirring of more general double-shaft mixer Time increases by 3 times.
The drive device of mixer is to drive the reductor 2 that speed reducing ratio is 20 by vee-pulley by 11 kilowatts of motor 1 The gear pair 4 coaxial with left and right revolving body is driven through end-float coupling 3 and is realized.It is reverse that revolving body 6,7 makees constant speed when working Rotation, its direction of rotation is as shown in accompanying drawing 3 14,15.Motor 1, decelerator 2, bearing 5 are fixed on together with casing 8 On base 9.
Using mixer as described above, when the rotating speed of motor 1 is 970 turns per minute, revolving body rotating speed is every Minutes 28.7 turns, can batch mixing amount be 26.69 tons per hour, ash content undulate quantity error amount is ± 1.1% after former secondary material mixing, mixing Material per ton(Coal)Consumption power be 0.423 kilowatt, than single mixer reduce by 15.4%, work noise be not more than 63.
