The application of rubber for tire in pavement engineering starts from U.S. of the forties in 20th century the earliest.The sixties in 20th century, American charles MacDonald (Charles H.McDonald) has invented rubber asphalt.The eighties, highway or high-grade highway are built by states such as the U.S., Japan, Russia, Canada, Sweden, Korea S, Finland successful Application scrap gum modified pitch; At this moment, rubber asphalt obtained Primary Study in China and uses, and had obtained fast development in nearly ten years.The characteristics of rubber asphalt are that high-temperature stability and low-temperature cracking-resistance are good, can prevent high temperature rut and low temperature crack effectively; Have the ability of stronger reduction road surface stress, can prevent reflection crack effectively, the significant prolongation cover layer life-span.Rubber asphalt is the new material that urban road reduces noise, compares with the plain asphalt road surface, can reduce noise; Watertightness is good, and is anti-aging; Top course thickness also can attenuate, and prolong than plain asphalt service life, thereby reduces the road maintenance expense.Because rubber asphalt superperformance and very high environmental-protecting performance will be more widely used in the later foster construction of building the road of China.
The heated bitumen of producing at present the most general method of rubber asphalt and being 20-80 purpose waste tyre rubber powder and 190 ℃-200 ℃ joins in the blender in proportion, is extracted into reactor with pump and reacts 45 minutes in 190 ℃-205 ℃ through stirring the back.So the mixed effect of blender is the extremely important factor that influences the rubber asphalt index.
Current, China has the ability, and to produce the enterprise of rubber asphalt equipment also few in number in research and development, from import equipment cost an arm and a leg, complicated operation and inconvenient maintenance.On the market in the existing rubber asphalt equipment blending tank mostly mixed effect is undesirable; And exist unmixed just directly to be extracted out the situation of blending tank by bitumenpump; And because room temperature has only 10-40 ℃, production brings fatal interference to rubber asphalt because the too fast easy appearance of cooling " knot pot " phenomenon influences when harsh product.Current rubber asphalt production equipment presses for the Hi-mixer of the full and uniform mixing of configuration energy.
The situation of comprehensive prior art is not difficult to find that there are following three shortcomings in rubber asphalt production equipment medium pitch and rubber powder blender: 1. mix even inadequately; 2. exist unmixed just directly to be extracted out phenomenon by bitumenpump; 3. " knot pot " phenomenon appears when just having begun to produce easily.

Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the accompanying drawing 1, the present invention mainly is made of agitator and blending tank, described blending tank is made up of interior bucket 9 and outer bucket 11 inside and outside fits, agitator includes an agitator body 4 that is installed in blending tank top, one shaft 8 stretches out from the agitator body 4 that is assembled together, and stretch in the interior bucket 9 of blending tank, stirring vane 12 and fixing runner 13 are housed on shaft 8 terminations in interior bucket 9; Be respectively arranged with the pitch oil-in 17 and and the powder import 7 that are connected to interior bucket 9 tops by drainage plate on the outer bucket 11.
Outer dish has heat-conducting oil pipes 20 on the outside wall surface of described outer bucket 11, and is surrounded by aluminum silicate insulation material layer 21 outside on barrels 11 the outside wall surface this is described outside.
Normally closed and mixing the drain tap of just opening when finishing 14 when oil-out 10 that described outer bucket 11 sidewalls open wide when being provided with work and work, and oil-out 10 is up, drain tap 14 below.
The upper portion side wall of bucket 11 is provided with outer barrel of overflow pipe 18 interior, that prevent to stop up of a connection outside described; Outer bucket 11 is provided with oil sealing 6 with the joint of shaft 8.
The agitator body 4 that install described outer bucket 11 tops includes a motor 1, and this motor 1 links to each other with shaft 8 by shaft coupling 2, and shaft 8 is placed on the agitator body 4 by two bearings 3, and described agitator body 4 is provided with cooling device.
Described cooling device is included in cooling water inlet 15 and coolant outlet 5 and the lubricating oil pouring orifice of offering on the main body outer wall 16.
The present invention has mainly solved the three big shortcomings that following prior art exists:
1. mixing is even inadequately, is summed up as the form that mixes of blender and the structure problem of blending tank.Technical solution of the present invention makes pitch and rubber powder that mixed effect better be arranged for the stirring vane of redesign blending tank.Change the oil-out position of blending tank in addition; Above one be oil-out, work is opened often, following be drain tap, normally closed and just open when mixing end during work, so that structure is more reasonable.
2. second shortcoming also is structure problem.For overcoming this problem, through testing and verification result for several times, the technical solution that the present invention proposes is for to be designed to inside and outside barrel structure with blending tank, like this pitch and rubber powder can interior bucket mixes relatively more abundant after barrel extraction blender outside the warp again.
3. " knot pot " phenomenon of blender is summed up as temperature problem.Because because the temperature difference is bigger, there is a fast cooling process in pitch when pitch just enters blender, when pitch 130 ℃ in addition when following mobile performance just very poor, " knot pot " phenomenon appears so add mixing very easily of rubber powder.The technical solution that the present invention proposes be to coil heat-conducting oil pipes and outsourcing aluminum silicate insulation material outside outside blending tank.Because the heat-conducting oil system that rubber asphalt carries can be started working earlier with before the rubber asphalt production, so because the blender heat-conducting oil pipes coils outward, when equipment began to produce by the time, the air themperature of blending tank had reached 130-150 ℃, since less with the pitch temperature difference, just there is not " knot pot " phenomenon.And the outer dish of deep fat pipe asphalt temperature can not occur too high and make ageing of asphalt.
Pitch can carry out high-revolving fully the mixing again at interior bucket 9 earlier with rubber powder and be got rid of by urceolus oil-out 10.And require the novel stirring vane of design to make mixing effect have two liquid circulations up and down according to technical solution of the present invention one, even more ideal than the effect of general stirring vane.
Shown in the figure, the present invention mainly contains two parts and forms: agitator and blending tank; Stirring is installed on the double barrels type blending tank.
Agitator body 4 is assembled together itself and shaft 8 by two bearings 4; Stirring vane 12 and fixing runner 13 are housed on the shaft termination; Motor 1 drives the shaft rotation by shaft coupling 2, and stirring vane 12 gets rid of pitch and waste rubber tyre powder to get out to reach rapidly under rotating at a high speed and mixes purpose.
For guarantee that pitch can fully mix with waste rubber tyre powder in blender, blending tank of the present invention adopts double barrels type, and pitch and waste rubber tyre powder mix at interior bucket, and bucket is extracted out solidliquid mixture by bitumenpump outside.Pitch is according to setting flow through oil-in 17, waste rubber tyre powder advanced powder import 7 according to setting speed and entered bucket 9 in the blending tank, extracted out by bitumenpump from the oil-out 10 of outer bucket then, when the end of job, drain tap place valve open is discharged blending tank bottom rubber asphalt.
In addition, mixing tube is furnished with overflow pipe, with prevent equipment occur beyond situation so that blender stop up; Below pitch oil-in 17 and powder import 8, all have drainage plate in addition, so that pitch and the following current of rubber powder energy increase mixing effect to mixing position.
Because room temperature is substantially at 10-40 ℃, be to guarantee rubber asphalt production temperature, particularly just having started working, it is too fast can not lower the temperature first pot the time; The present invention adds the thermal conductive oil pipeline insulation outside the bucket 11 outside blender, because rubber asphalt equipment can be opened earlier before production and add hot oil furnace equipment conduction oil is warming up to 200-250 ℃, the air themperature of blender before work can reach 120-150 ℃ and can not tie pot during with first pot of assurance work like this.The present invention also outside blending tank bucket 11 add alumina silicate heat-preservation cotton and guarantee temperature in the blenders.
Because the agitator tank medium pitch has 180-200 ℃ of temperature, for guaranteeing agitator steady running for a long time, oil sealing 6 at first is being equipped with in the present invention on agitator body; Secondly, on the agitator body 4 cooling system is housed, water is gone out the operating temperature that circulation reduces shaft main body 4 and bearing 3 through import 15 by outlet 5; After working after a while, can also inject lubricating oil inward so that prolong the bearing working life-span simultaneously by pouring orifice 16.
