Description
Technical field
The utility model relates to a kind of plant equipment, particularly relates to a kind of coated sand mixer.
Background technology
Hot method coating technique adds in puddle mixer by the roughing sand of the constant weight being heated to uniform temperature, by a graded, the resin of constant weight, lubricant and curing agent are added in mulling process, then shake out, broken, screening, cooling, namely make the dry state thermosetting molding sand containing latent curative, lubricant, binding agent.Therefore the quality of equipment, the mixing effect of the puddle mixer that especially hot method coating technique adopts directly has influence on the uniform and smooth property of the resin coating of precoated sand, so that affects each side such as quality and production efficiency of its strength degree, mobility and mouldability.
In prior art, S2120 type puddle mixer, not only revolved round the sun but also the rotor of autobiography by two, the end, side scraper plate and forming in addition, its Problems existing is: 1) the revolution rotating speed of two rotors is low, and the diameter of rotor is less than normal, take up space little, so that rotor institute takes up space and the mixing velocity of the material such as the sand grains in most of space beyond wave zone and binding agent not, make overlay film less effective, precoated sand intensity is not high; 2) stirring structure is complicated, and cost is high, and scraper plate easily damages, and rotor electric machine easily burns.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of coated sand mixer, and the advantage of this coated sand mixer is that structure is simple, long service life, and mixing effect is good, and then it is inadequate to solve existing puddle mixer mixing velocity, the problems such as complex structure.
The utility model is solved the problem by following technological means:
Coated sand mixer of the present utility model, comprise base, be vertically arranged on the cylindrical mixing drum of the open top above support, the below of described cylindrical mixing drum is coaxially fixedly installed rotating shaft, described base is provided with for supporting the pivotal supporting mechanism of described rotating shaft, the below of described mixing drum is also provided with the drive unit for driving described rotating shaft and mixing drum to rotate; The circumferential madial wall of described mixing drum is provided with multiple blade A extended in the middle part of mixing drum.
Further, described blade A distributes around the Axial-rotational Symmetry of described mixing drum.
Further, described blade A is axially set side by side with many groups along described mixing drum.
Further, also comprise be arranged on mixing drum inside agitator, for agitator described in axial restraint bracing frame and drive the motor of described agitator, described agitator comprises the shaft that is connected with motor-driven and multiple circumference and is arranged on the blade B extended to mixing drum madial wall above shaft, described blade B is axially set side by side with many groups along shaft, often organizes blade A and often organize blade B to arrange at interval successively.
The beneficial effects of the utility model: coated sand mixer of the present utility model, comprise base, be vertically arranged on the cylindrical mixing drum of the open top above support, the below of described cylindrical mixing drum is coaxially fixedly installed rotating shaft, described base is provided with for supporting the pivotal supporting mechanism of described rotating shaft, the below of described mixing drum is also provided with the drive unit for driving described rotating shaft and mixing drum to rotate; The circumferential madial wall of described mixing drum is provided with multiple blade A extended in the middle part of mixing drum.Coated sand mixer of the present utility model rotates drive crushing material and fully mixing in it when stirring by the positive and negative intermittent high-speed of mixing drum, in addition, it eliminates very complicated agitator structure compared with existing puddle mixer, and durability degree is significantly improved.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the perspective view of the utility model coated sand mixer;
Fig. 2 is the cross-sectional view of the utility model coated sand mixer;
Fig. 3 is the top view of the utility model coated sand mixer.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail:
As shown in Figures 1 to 3, coated sand mixer in the present embodiment, comprise base 1, be vertically arranged on the cylindrical mixing drum 2 of the open top above support, the below of described cylindrical mixing drum 2 is coaxially fixedly installed rotating shaft 3, described base 1 is provided with for supporting the pivotal supporting mechanism 4 of described rotating shaft, described supporting mechanism 4 adopts axial thrust bearing, the below of described mixing drum 2 is also provided with the drive unit 8 for driving described rotating shaft 3 and mixing drum 2 to rotate, and described drive unit is made up of motor and decelerator; The circumferential madial wall of described mixing drum 2 is provided with multiple blade A21 extended in the middle part of mixing drum 2.During work, drive unit drives mixing drum 2 intermittent high-speed to rotate, and drives overall material in it to rotate simultaneously, therefore there will not be agitator in the past to stir the situation less than material, also eliminates and must arrange the structures such as scraper plate in the past.Coated sand mixer of the present utility model rotates drive crushing material and fully mixing in it when stirring by the positive and negative intermittent high-speed of mixing drum, in addition, it eliminates very complicated agitator structure compared with existing puddle mixer, and durability degree is significantly improved.
As the further improvement of technique scheme, described blade A21 distributes around the Axial-rotational Symmetry of described mixing drum 2, to strengthen Agitation and mixing effect.
As the further improvement of technique scheme, described blade A21 is axially set side by side with many groups along described mixing drum 2; Also comprise be arranged on mixing drum 2 inside agitator, for agitator described in axial restraint bracing frame 6 and drive the motor 7 of described agitator, described agitator comprises the shaft 51 that is connected with motor-driven and multiple circumference and is arranged on the blade B52 extended to mixing drum 2 madial wall above shaft 51, described blade B52 is axially set side by side with many groups along shaft 51, often organizes blade A21 and often organize blade B52 to arrange at interval successively.During work, intersected and reverse high-speed motion by blade A21 and blade B52, can greatly improve fragmentation and mixed.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
