Abstract
The utility model discloses a pitch spray tube device for pitch concrete mixer, which comprises a pitch spraying tube body, one end of the pitch spraying tube is sealed, the other end is connected with a pitch transporting passage, the around wall of the pitch spraying tube is opened a plurality of spraying holes, the pitch spraying tube device also comprises a heat preservation tube which is around the periphery surface of the pitch spraying tube body, a sealing hot transmit oil cavity is formed between the heat preservation tube and the pitch spraying tube body, the heat preservation tube is provided with a hot transmit oil entrance and an exit, a pitch spraying head is arranged at the spraying opening of the pitch spraying tube body, the pitch spraying head extends out the heat preservation. The utility model can lead the hot transmit oil into the hot transmit oil cavity before turning on the machine in winter to melt the pitch solid in the pitch spraying head, and then turn on the machine to run, which is safe and convenient.
Description
Technical field
The utility model relates to bituminous concrete agitator technical field, relates in particular to a kind of pitch shower device that is used for the bituminous concrete agitator.
Background technology
The fast development of building along with highway in China, the demand of Stabilized Soil, cement concrete and the bituminous concrete that road surface pavement is used is increasing, and quality requirement is more and more higher.On the engineering, these several concrete adopt plant mix equipment production mostly, concerning bituminous concrete, agitator is one of critical piece of plant mix equipment, when aggregate and powder are stirred, need spray pitch in agitator, when normally using, the temperature of pitch is about 150 ℃, any problem can not appear generally, but when starting shooting winter, the pitch that solidifies can stop up the spray apertures on the pitch jet pipe, thereby influence the normal use of agitator, home equipment mostly adopts the original method of burning when running into this situation, not only danger but also bother.
The utility model content
Technical problem to be solved in the utility model is: a kind of pitch shower device that is used for the bituminous concrete agitator is provided, and when starting shooting winter to solve, the pitch that the pitch spray apertures usually is solidified stops up, thereby influences the normal problem of using of agitator.
For solving the problems of the technologies described above, the technical solution of the utility model is: the pitch shower device that is used for the bituminous concrete agitator, comprise the pitch spout body, the one end sealing of described pitch spout body, the other end is connected with the asphalt delivery pipeline, offer several spray apertures on the perisporium of described pitch spout body, this pitch shower device also comprises an insulating tube around described pitch spout body outer peripheral face, between insulating tube and pitch spout body, form the heat conduction oil pocket of sealing, described insulating tube is provided with heat conductive oil inlet and conduction oil outlet, mouth spray place in described pitch spout body is provided with Asphalt-distributing spray head, and described Asphalt-distributing spray head stretches out the outside of described insulating tube.
As a kind of improvement, in described heat conduction oil pocket, be provided with partition wall longitudinally, described partition wall is divided into oil suction chamber and oil back chamber with the heat conduction oil pocket, described oil suction chamber and oil back chamber are communicated with at an end of insulating tube, described heat conductive oil inlet is communicated with oil suction chamber, described conduction oil outlet is communicated with oil back chamber, and all is positioned at the end away from described oil suction chamber and oil back chamber connection of insulating tube.
Improve as another kind, described Asphalt-distributing spray head is provided with electric heater unit.
After having adopted technique scheme, the beneficial effects of the utility model are: because this pitch shower device also comprises an insulating tube around described pitch spout body outer peripheral face, between insulating tube and pitch spout body, form the heat conduction oil pocket of sealing, thereby in the time of can be before winter start, at first conduction oil is introduced the heat conduction oil pocket, the pitch that will solidify dissolves, and then the start operation, and is safe and convenient.Owing in described heat conduction oil pocket, be provided with partition wall longitudinally, described partition wall is divided into oil suction chamber and oil back chamber with the heat conduction oil pocket, described oil suction chamber and oil back chamber are communicated with at an end of insulating tube, described heat conductive oil inlet is communicated with oil suction chamber, described conduction oil outlet is communicated with oil back chamber, and all be positioned at the end that is communicated with away from described oil suction chamber and oil back chamber of insulating tube, like this, conduction oil at first enters oil suction chamber from oil-in, and then enters oil back chamber, flows out from oil-out, thereby whole heat conduction oil pocket does not stay the dead angle, temperature is even, and the pitch at each jet place can dissolve in the identical time substantially, is convenient to control automatically.Simultaneously, oil-in and oil-out are positioned at the same side, are convenient to the installation of heat conducting oil pipe.Because Asphalt-distributing spray head stretches out outside the insulating tube, sometimes it is slower to remain in the speed that the pitch in the shower nozzle dissolves by the mode of conducting, so, electric heater unit is set on Asphalt-distributing spray head, the pitch that inside is retained is accelerated to dissolve, and has further guaranteed the reliability of pitch spray operation.
Description of drawings
