Background technology
Rubber asphalt from 19th-century sixties after the State of Arizona, US invention, be extensive use of the applicating history in existing more than 40 year by all over the world highway.The characteristics of rubber asphalt maximum are effectively to reduce the generation in the various cracks on the highway pavement, comprise reflection crack, low temperature crack and fatigue crack, reduce the disease that bring in the crack.Rubber asphalt is mainly used in stress absorbing layer and stress absorption intermediate layer, and its compound thickness is thinner than general bituminous mixture, can effectively improve the life-span and the cracking resistance seam ability of road.At present, in developed country, rubber asphalt extensive use in highway engineering, its pavement performance is better, has the noise reduction effect, helps solving the black pollution problem that junked tire brings.
In the rubber asphalt manufacturing process, stirring and temperature control system are the cores of entire equipment, often owing to stir not in place, make material not through fully stirring just precipitation, perhaps temperature control is bad, can not carry out quick swelling reaction, thereby has reduced the yield rate of product.
Summary of the invention
The utility model mainly provides a kind of stirring, high insulating effect, the rubber asphalt reaction unit of the saving energy; Solve existing in prior technology rubber asphalt reaction unit and stir the temperature control inefficacy, waste energy, efficient is low, is difficult to produce the technical problem of qualified products.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of rubber asphalt reaction unit, comprise reacting tank body, in reacting tank body, be provided with the central rotating shaft that drives by reducer, on described central rotating shaft, be provided with stirring vane, described central rotating shaft and stirring vane are positioned at the bottom of tank body, the insulation heat-conducting oil pipes is installed on the sidewall of reacting tank body, heater is installed in reacting tank body.Stirring vane is positioned at the bottom of tank body, material constantly can be stirred, and prevents its precipitation segregation, simultaneously, has guaranteed normal operating temperature in the retort, thermal efficiency height at the insulation heat-conducting oil pipes of the sidewall of reacting tank body.Quick heating apparatus is set in agitator tank, can carries out the regulation and control of flexible moment, guarantee the reliable and stable of reaction temperature operating temperature required in the retort.Of the present utility model simple in structure, high insulating effect stirs.
As preferably, described stirring vane is shape in the shape of a spiral, and stirring vane is divided into two sections vertically, and the rotary orientation of two-stage agitation blade is opposite.Stirring system adopts reducer to drive spiral agitator, how high the hand of spiral of helical mixing blade have, and the hand of spiral counter opposition of every pitch, causes the constantly collision mutually of reaction mass in the stirring, make reaction mass can not precipitate segregation, can carry out the swelling reaction again fast.
As preferably, described insulation heat-conducting oil pipes is positioned at the both sides of described stirring vane, and the insulation heat-conducting oil pipes is a sinuous coil, and the insulation heat-conducting oil pipes is extended to 1/2～3/5 place of tank body short transverse to the tank body two side by stirring vane.Stirring vane is positioned at the bottom at tank body center, and the insulation heat-conducting oil pipes extends by the bottom of stirring vane is upwards sinuous, and the material that is positioned at tank body is incubated, and half of the height of the aspect ratio tank body that wriggles up of insulation heat-conducting oil pipes is slightly high to get final product.The height of insulation heat-conducting oil pipes only need guarantee the temperature stabilization of material part.
As preferably, described heater comprises burner and the heating flame passage that links to each other with burner, and described heating flame passage is positioned at the top of described stirring vane, and described heating flame passage height of living in is 1/4～3/10 place of tank body height.Can make the interior required operating temperature of retort carry out the regulation and control of flexible moment, guarantee the reliable and stable of reaction temperature.
As preferably, the external surface of described reacting tank body is provided with adiabator layer.Can make heat energy obtain fully enough utilizations, guarantee the normal working temperature in the retort, the thermal efficiency is very high.
Therefore, rubber asphalt reaction unit of the present utility model has following advantage: 1, stirring vane is positioned at the tank body of retort, can make constantly collision mutually of reactant, and can not precipitate segregation, and swelling reaction is fast arranged; 2, the adiabator layer on reacting tank body surface and in the multiple tracks multitube insulation heating heat-conducting oil pipes established, can make heat energy obtain fully enough utilizations, guaranteed the normal working temperature in the retort, the thermal efficiency is very high; 3, the quick heating apparatus of burner and flame pipeline composition can make the interior required operating temperature of retort carry out the regulation and control of flexible moment, guarantees the reliable and stable of reaction temperature.
Description of drawings:
Fig. 1 is the main TV structure schematic diagram of rubber asphalt reaction unit of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the A-A sectional view of Fig. 1.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
Shown in Fig. 1 and 2 and 3, a kind of rubber asphalt reaction unit comprises " U " shaped reaction jar 1, is enclosed with adiabator layer 2 at the external surface of retort 1, guarantees that temperature in the tank body and heat do not leak outwards to distribute.Centre bottom in retort 1 is connected with central rotating shaft 4 by reducer 3, and the stirring vane 5 on central rotating shaft 4 is shape in the shape of a spiral, and stirring vane 5 is divided into two sections vertically, and the rotary orientation of two-stage agitation blade 5 is opposite.In the both sides of retort 1 inwall snakelike insulation heat-conducting oil pipes 6 is installed, insulation heat-conducting oil pipes 6 is extended to the two side of tank body by the stirring vane 5 of tank base, and the height of the insulation layer that insulation heat-conducting oil pipes 6 forms is 3/5 (as shown in Figure 4) of retort 1 tank body height.Above central rotating shaft 4, be provided with heating flame passage 7, heating flame passage 7 links to each other with tank body burner 8 outward, consider that provincialism temperature difference and emergency case cause when a jar interior temperature descends, can start burner, its flame is flame in the heating flame pipeline in jar directly, impel temperature moment rising in the retort, it is reliable effectively to have controlled the interior temperature constant of retort.
In use, before in the reaction mass input reacting tank body, start the circulation preheating work of conduction oil in the heat tracing heat-conducting oil pipes earlier, be preheating to when having certain requirements temperature in the reacting tank body, again in the reaction mass input reacting tank body, and start reducer simultaneously and spiral agitator stirs.In whipping process, because the helical blade in the spiral agitator has the hand of spiral of more piece or every pitch opposite, make reaction mass generation sharp impacts and seethe, avoided reaction mass deposition segregation, impel reaction mass swelling reaction fast.When stirring, the temperature in the reacting tank body is generally speaking by the control that automatically adjusts of conduction oil flow in the multiple tracks multitube heat tracing heat-conducting oil pipes and flow velocity.Temperature differs too big in the reacting tank body if cause for some reason, promptly starts burner, carries out flame in the heat tracing flame pipeline in reacting tank body, makes till its job requirement that is rapidly heated.
