Abstract

High speed shearing grinder for modified bitumen, it comprises high-speed motor, moving cut ring, quiet cut ring and pump shell, moving cut ring is connected on the high-speed motor connecting axle, quiet cut ring is installed on the pump shell, charging aperture and discharging opening are arranged on the pump shell, it is characterized in that: centrifugal self-priming blade also is connected on the high-speed motor connecting axle, and the periphery place of centrifugal self-priming blade is the quiet tool bore of quiet cut ring and the moving knife hole of moving cut ring successively.When high-speed motor rotated, the self-priming blade was pressed to quiet tool bore with material, and simultaneously self-priming blade and moving cut ring are also and finish twice shear history between the quiet cut ring.Process and time that the present invention is dissolved in hard pitch according to SBS refine to SBS cutting and can accelerate course of dissolution and can avoid a large amount of cutting heat again and extremely stretch producing, thereby reach energy savings, improve output, stabilised quality, reduce investment outlay.

Description

High speed shearing grinder for modified bitumen
Technical field
The present invention relates to a kind of process equipment of important materials pitch of highway.
Background technology
Be accompanied by the construction of Chinese Road, the highway of domestic each province and belt express passway on average are open to the traffic with the progress in 200 kilometers of every year over past ten years, the year use amount that makes China be used to build the important materials pitch of highway breaks through 3,000,000 tons, simultaneously the also unusual attention of the quality of national road pavement and service life.
The grinding machine of existing production modified pitch is representational to be the colloid mill of axle head fluted disc, cuts when material enters slot, and different is the number of teeth of cutting and the size in slot crack, makes the granularity of material finally reach requirement.But do not have suction capacity to need the outside front pump that is equipped with same traffic to work, can produce very big cutting heat at work, the energy consumption root is big, and the Process configuration cost increases, and price is very expensive.According to about 200,000 dollars of the about needs of the difference of flow.
In fact in the production of modified pitch main production difficult point be how with SBS equably dispersing and dissolving in pitch, dissolving just will be convenient in the order ground of refinement, and be not that the dissolving of refinement more is just fast more, certain effect of fluxing is arranged, but the dissolving of SBS is the time definitely, if in other words can not the just direct entrucking in overground back use with very thin colloid mill, so do not need aborning to grind SBS too thin, the SBS that mixes when pitch reaches 185 ℃ at high temperature has been the rubber bodies of softening, can produce a large amount of cutting heat and extremely stretch with the colloid mill in finedraw crack too softening rubber bodies, cause product ductility index instability.
Summary of the invention
The purpose of this invention is to provide a kind of high speed shearing grinder for modified bitumen, it has following advantage: 1, low power consuming: only need the power consumption of 1/2 colloid mill; 2, have suction capacity, need not to dispose in addition delivery pump; Simplify the production technology configuration, lowered cost of investment; 3, cheap, have only about 1/5 of colloid mill.4, there is not the generation of a large amount of cutting heats.
Technical scheme of the present invention is: a kind of high speed shearing grinder for modified bitumen, it comprises high-speed motor, moving cut ring, quiet cut ring and pump shell, moving cut ring is connected on the high-speed motor connecting axle, quiet cut ring is installed on the pump shell, charging aperture and discharging opening are arranged on the pump shell, it is characterized in that: centrifugal self-priming blade also is connected on the high-speed motor connecting axle, and the periphery place of centrifugal self-priming blade is the quiet tool bore of quiet cut ring and the moving knife hole of moving cut ring successively.When high-speed motor rotated, the self-priming blade was pressed to quiet tool bore with material, and simultaneously self-priming blade and moving cut ring are also and finish twice shear history between the quiet cut ring.
Useful effect: this high speed shearing grinder for modified bitumen mainly is to design at the characteristics of modified pitch production, cooperate modified pitch that corresponding production technology produces no less than the effect of colloid mill in actual production, reach and surpassed the relevant national standard of modified pitch, benefit and effect highly significant.
Process and time that the present invention is dissolved in hard pitch according to SBS refine to SBS cutting and can accelerate course of dissolution and can avoid a large amount of cutting heat again and extremely stretch producing, thereby reach energy savings, improve output, stabilised quality, reduce investment outlay.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the operation principle schematic diagram of the embodiment of the invention.
Concrete embodiment
The explanation of mark among Fig. 1: 1-high-speed motor; The centrifugal self-priming blade of 2-; 3-moves cut ring; The quiet cut ring of 4-, 5-connecting axle, 6 pump shells, 7-adpting flange, the quiet tool bore of 8-, 9-moving knife hole.
The high speed shearing grinder for modified bitumen of the embodiment of the invention, it comprises high-speed motor 1, moving cut ring 3, quiet cut ring 4 and pump shell 6, moving cut ring 3 is connected on the high-speed motor connecting axle 5, quiet cut ring 4 is installed on the pump shell 6, charging aperture and discharging opening are arranged on the pump shell 6, it is characterized in that: centrifugal self-priming blade 2 also is connected on the high-speed motor connecting axle 5, and the periphery place of centrifugal self-priming blade 2 is the quiet tool bore 8 of quiet cut ring 4 and the moving knife hole 9 of moving cut ring 3 successively.When high-speed motor 1 rotated, self-priming blade 2 was pressed to quiet tool bore 8 with material, and self-priming blade 2 and moving cut ring 3 are also and finish twice shear history between the quiet cut ring 4 simultaneously.
Operation principle of the present invention is: drive the high speed rotation of centrifugal self-priming blade 2 and moving cut ring 3 by high-speed motor 1, use the edge of a knife in moving cut ring 3 and quiet cut ring 4 along outlet that material is all arranged on the circumference and cutting, the material that moving cut ring 3, centrifugal self-priming blade 2 threw away centrifugal force between quiet cut ring 4 together when material was thrown away along centrifugal direction has carried out the refinement cutting.Make its function that possesses self-priming owing to formed negative pressure after material is thrown out of, continuously mass transport is finished self-feeding and cutting in the cutting tool bore.
This grinding machine adopts high speed centrifugation self-priming blade to stop the mill butt formula of cutting refinement current drainage in outer ring simultaneously, effectively avoided in the thinning process to macromolecular material excessive stretching and the generation of friction high temperature, flow is big simultaneously, the output height.Detecting representative value in actual the use is: per hour flow is greater than 60 cubic metres, and single cut refinement degree is less than 1mm, and refinement is not evenly seen thread or strip capacitive material not.Have: high speed shear, big flow, self-priming, the production temperature has effectively been avoided the ageing of asphalt in the production process less than 185 degree, high energy consumption, hale stretch, the fluctuation of finished product index is big, yield poorly, and invests big defective.
The present invention can have following second or the mode of the third replacement.
Alternative plan: centrifuge blade is separated, will be pumped to such an extent that liquid guide flow cuts in another cavity volume, two to four cuttings can be arranged, and the chamber is continuous must cut.
Third party's case: the cut ring of deciding that increases the moving cut ring of multilayer and multilayer in the scheme of existing single layer cut is finished repeatedly cutting.
