Abstract

The utility model discloses a blender mixer with double shafts, and belongs to the field of blender mixers of cement industries. The blender mixer with the double shafts comprises a base, wherein two bearing seats and a shell are arranged on the base; two ends of the shell are provided with a feed inlet and a discharge outlet respectively; a stirring shaft is arranged between the two bearing seats; one end of the stirring shaft is connected with a driving device; and mixing blades are fixed on the stirring shaft. The blender mixer with the double shafts is characterized in that an aeration box is arranged at the bottom of the shell. The aeration box which is arranged at the bottom of the shell can blow up overstocked materials at the bottom of the shell, so that mixing efficiency and a mixing effect are improved, damages to a main shaft are reduced, cost is reduced, and energy consumption is reduced. The blender mixer with the double shafts is compact in structure and small in occupied space, runs stably and has a good sealing effect; materials are saved and are uniformly mixed; and compared with other blender mixers of which the yield is equal to that of the blender mixer, the blender mixer has the advantage that energy consumption is reduced.

Description

The biaxial mixing machine

Technical field

The utility model provides a kind of equipment that is used for the cement industry batch mixing, belongs to the batch mixer field, is a kind of biaxial mixing machine specifically.

Background technology

Need to add composite material at present in the cement in China industry cement flour, existing batch mixer mixes inhomogeneous, and exploitation biaxial mixing machine carries out batch mixing with cement flour and composite material, and batch mixing is even, guarantees to pack the back cement quality.

As shown in Figure 1, existing batch mixer is single shaft or twin shaft, on the axle blade is housed; Rotating shaft is driven rotary after motor reducer slows down, and blade stirs and plays compounding effect, this kind batch mixer main axis rotation; Two ends have bearing block to support; Housing is fixed, and material only mixes through blade in housing, undercompounding.

Chinese patent 201020118448.0 discloses a kind of dry powder single shaft batch mixer, and shaft is provided with some groups of mixing arms, on said each mixing arm, the stirring vane that is in tilted layout with said shaft is installed; In three groups of adjacent mixing arms, the stirring vane of wherein installing on two groups of mixing arms is feeding stirring vane forward, and the stirring vane of installing on other one group of mixing arm is returning charge stirring vane backward.This patent prolonged mixing time, accelerated batch mixing speed and batch mixing even, improved production efficiency and product quality, in addition; Solved the inconvenient problem of stirring vane of changing; Certain distance is arranged at the bottom but its blade still is the shrinking away from theshell body, and material overstocks at housing bottom, and batch mixing is insufficient.

The utility model content

According to above deficiency of the prior art, the problem that the utility model will solve is: provide a kind of material that prevents to overstock at housing bottom, batch mixing is even, the biaxial mixing machine of energy efficient.

The utility model solves the technical scheme that its technical problem adopted: the biaxial mixing machine; Comprise base, two bearing blocks and housing are installed on the base, the housing two ends are provided with charging aperture and discharging opening respectively; Between the diaxon bearing shaft is installed; Shaft one end is connected with drive unit, and the batch mixing vanes fixed is characterized in that on shaft: housing bottom is installed aeration tank.

At housing bottom aeration tank is installed and is said that the overstocked material of housing bottom blows afloat, improve batch mixing efficient and effect better, reduced the main shaft damage, reduced cost, practiced thrift energy consumption; Above-mentioned drive unit is a prior art, mainly comprises motor, and motor connects with reductor through shaft coupling, and reductor connects with shaft through shaft coupling again.

Wherein preferred version is:

Described aeration tank comprises casing, and the casing top is provided with ventilative cloth, hole UNICOM housing and casing on the ventilative cloth, and wall box is provided with compressed air inlet port.Compressed air inlet port connects air compressor, in aeration tank, inflates, and under the effect of ventilative cloth, the material that overstocks on ventilative cloth is blown afloat, and can make the batch mixing in the housing more even, improves compounding effect.

Described discharging opening is provided with the dust-precipitator mouth.Can connect dust-precipitator, prevent dust pollution, energy-conserving and environment-protective.

The beneficial effect that the utility model biaxial mixing machine is had is:

Realize the batch mixer operation through driving shaft, material is in charging aperture gets into housing, and under the effect of blade and aeration tank, material fully mixes in housing; And under the blade effect, move to discharging opening, the material that mixes draws off through discharging opening, all is provided with the mouth that gathers dust on the discharging opening, can connect dust-precipitator; The composite material batch mixing is even, has reduced mixing time, can prevent the long buckling of shells that causes running time; Prevent off-axis, reduce running wastage and reduce operating cost, energy efficient.

The utility model compact conformation, it is little to take up room, economical with materials; Operate steadily, sealing effectiveness is good, and batch mixing is even, compares energy efficient with other batch mixers with Isoquant.

The specific embodiment

Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:

As shown in Figure 2, the biaxial mixing machine comprises base 14, and two bearing blocks 10 and housing 2 are installed on the base 14; Housing 2 two ends are provided with charging aperture 1 and discharging opening respectively, and shaft 4 is installed between the diaxon bearing 10, and shaft 4 one ends are connected with drive unit; Be provided with batch mixing blade 3 in the housing 2, batch mixing blade 3 is fixed on the shaft 4, and aeration tank 11 is installed in housing 2 bottoms; Aeration tank 11 tops are provided with ventilative cloth 12, and its sidewall is provided with air inlet 13, and discharging opening is provided with dust-precipitator mouth 5.

Drive unit of mentioning in the utility model and mounting technique are common prior art; Mainly comprise motor 8; Motor 8 connects with reductor 7 through shaft coupling 9, and reductor 7 passes through shaft coupling 6 again and connects with shaft 4, its setting and be used for industry technical staff and grasp.

In running.Realize the batch mixer operation through drive unit band driving shaft; Material gets in the housing 2 through charging aperture 1, and under the effect of blade 3 and aeration tank 11, material fully mixes in housing 2; And under 3 effects of batch mixing blade, move to discharging opening; The material that mixes draws off through discharging opening, all is provided with the mouth that gathers dust on the discharging opening, can connect dust-precipitator.
