Abstract

The invention relates to an axial high-rate diffusion device of a dual-shaft mixer, which is characterized in that the device is arranged at the middle part above two mixing shafts and the track circle of rotating of a flying cutter has tangency with the track circle of the mixing of mixing vanes on the two mixing shafts. A motor is fixed on a bracket which is fixed on the flange of a mixing cylinder, the input end of a rotary shaft is supported by a bearing which is fixed on the bracket; a cutter base is welded to the rotary shaft and the flying cutter is fixed on the cutter base; the input end of the rotary shaft is connected with the output shaft of the motor through a coupling device. The axial high-rate diffusion device enlarges the range of application of the dual-shaft and vane-typed mixer, can be applicable to the mixing of trace added material, and has convenient installation and adjustment and simple operation and maintenance; the flying cutter and the cutter base are adjustable, and the flying cutter can be adjusted according to the wearing thereof for remaining the track circle and prolonging the service life; the device can improve the mixing capacity of the mixer andin particular the trace materials in the mixed materials can be quickly and evenly diffused to achieve high effectively mixing.

Description

Double-shaft mixer axial high speed dispersing device

Technical field

The present invention relates to a kind of double-shaft mixer axial high speed dispersing device, specifically mainly be matched in twin shaft paddle formula mixer.

Background technology

Along with China's development of economic construction, novel green construction material-dry-mixed mortar with its superior quality guarantee, environmental protection and easily construction technology obtained applying widely at building energy conservation, waterproof, insulation, facing, each the realm of building construction of gravity flow equality, also the batch production production of these materials is had higher requirement.It is twin shaft paddle formula mixer that the main mixer that adopts is produced in batch production, mix the mix ability efficiently and obtained extensive use with it in dry-mixed mortar factory, continuous increase and raising along with the dry-mixed mortar variety and quality, trace in the dry-mixed mortar adds raw material and is widely adopted more, as the fortifying fibre in the anticracking grout, colorant in the facing mortar (pigment), these trace add the shared ratio of raw materials only be ten thousand/to 100,000/, on original mixer, can only prolong incorporation time, but also not reach dispersion cmpletely and mix.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of double-shaft mixer axial high speed dispersing device, can improve the mixing ability of mixer, especially for the less material of content in compound by the shedding of axial high speed dispersing device, it can be disperseed rapidly equably and reach the purpose of efficient mixing.

Main solution of the present invention is achieved in that

The present invention adopts high speed dispersing device to be installed in two centre positions, top of mixing axle, and the fly cutter locus circle is tangent with two locus circles of mixing leaf; Described high speed dispersing device adopts motor to be fixed on the support, support is fixed on first and mixes on the drum flange, and the rotating shaft input is supported by clutch shaft bearing, and clutch shaft bearing is fixed on the support, the output of rotating shaft supports with second bearing, and second bearing fixing is mixed on the drum flange second; Tool rest is welded in the rotating shaft, and fly cutter is fixed on the tool rest, and the rotating shaft input links with shaft coupling and motor output shaft.

Compared with the prior art the present invention has the following advantages:

1, enlarges the scope of application of twin shaft paddle formula mixer, can adapt to the mixing that trace adds raw material.

2, integral structure is installed easy to adjustly, and working service is simple, can be used for the transformation of existing twin shaft blade-paddle mixer.

3, fly cutter and tool rest are design-adjustable, can adjust fly cutter according to wear extent, make the fly cutter locus circle constant, increase the service life.

4, can improve the mixing ability of mixer, especially for the less material of content in compound by the shedding of axial high speed dispersing device, it can be disperseed rapidly equably and reach the purpose of efficient mixing.

Description of drawings

Fig. 1 is an axial high speed dispersing device scheme of installation of the present invention.

Fig. 2 mixes the axle and the user mode figure of high speed dispersing device for twin shaft paddle mixer of the present invention.

The specific embodiment

Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1 and Figure 2, comprise and mix tube 1, mix axle 2, mix leaf 3, reductor 4, high speed dispersing device 5, motor 6, bolt 7, support 8, shaft coupling 9, bolt 10, clutch shaft bearing 11, bolt 12, first and mix drum flange 13, rotating shaft 14, tool rest 15, fly cutter 16, bolt group 17, second bearing 18, bolt 19, second and mix drum flange 20 etc.

The present invention mix leaf 3 be installed in mix the axle 2 on, by reductor 4 driven rotary, high speed dispersing device 5 is installed in two centre positions, top of mixing axle, fly cutter 16 locus circles are tangent with two locus circles of mixing leaf 3, mixing leaf 3 rotates in opposite directions along mixing 1 liang of circular arc ecto-entad of tube, material is held up to the centre, rotate at a high speed mixing the material high-speed projectile that leaf 3 holds up by the fly cutter 16 that is installed in the rotating shaft 14, make it be scattered in the surface of mixing an interior material equably, circulation so repeatedly, quicken the mixing of material, improved the mixing uniformity of micro-material.

Motor 6 usefulness bolts 7 of the present invention are fixed on the support 8, support 8 usefulness bolts 12 are fixed on first and mix on the drum flange 13, rotating shaft 14 inputs of described high speed dispersing device 5 are by clutch shaft bearing 11 supportings, clutch shaft bearing 11 usefulness bolts 10 are fixed on the support 8, the other end of rotating shaft 14 (output) supports with second bearing 18, and second bearing, 18 usefulness bolts 19 are fixed on second and mix on the drum flange 20.Tool rest 15 is welded in the rotating shaft 14, and fly cutter 16 usefulness bolt groups 17 are fixed on the tool rest 15, and the rotating shaft input links with shaft coupling 9 and motor output shaft, and motor power is delivered in the rotating shaft.Drive fly cutter and rotate at a high speed, impel material to disperse fast, reach the function that improves mixing uniformity.

The principle of the present invention and the course of work:

The fly cutter blade rotational trajectory circle of high speed dispersing device of the present invention is middle above twin shaft paddle stirring locus circle, and it is tangent with two stirring locus circles, mixed material is mixed at two shafts under the impetus of leaf and is piled up a hilltop two centres, the rotational trajectory circle of just topped high speed dispersing device fly cutter blade, and hold on the high speed dispersing device of putting this position numerous fly cutter blades of evenly arranging under rotation at a high speed, two shafts are mixed leaf to be pushed to place, the hilltop material that comes and outwards sheds rapidly, make it shed surface equably at mixed material, mixed leaf by two again and admix material → push into the hilltop → high speed dispersion to shed → admix material, circulate so repeatedly and make it reach abundant dispersion in the short period of time, mixed uniformly purpose.
