In the embodiment, when the asphalt storage tank is used, asphalt is stored by using the storage tank 2, when the asphalt needs to be heated, the steam generator 10 is started to work, steam generated by the steam generator 10 sequentially flows into the steam cavity 5 on the left side through the steam exhaust pipe 11 and the steam inlet pipe, the steam flowing into the steam cavity 5 on the left side sequentially flows into the steam cavity 5 on the right side through the steam transmission pipes 6, finally flows back into the steam generator 10 through the steam exhaust pipe 11 and the steam return pipe 12 to be heated, when the steam flows in the two steam cavities 5 and the steam transmission pipes 6, heat in the steam is transferred to the asphalt, the asphalt can be heated, the starting motor 13 works, under the meshing transmission action of the driving straight gear 14 and the driven straight gear 15, the steam inlet pipe 8, the steam outlet pipe 9, the two disks 4 and the steam transmission pipes 6 can be controlled to rotate, so that the steam flows in the two disks 4 and the steam transmission pipes 6, the heat in the steam can be fully and effectively transferred to the asphalt, the rotation of the two disks 4 and the steam pipes 6 is utilized to play a role of stirring the asphalt, so that the movement range of the asphalt in the storage tank 2 is enlarged, the asphalt is uniformly heated, the heating efficiency of the asphalt is improved, the temperature of the asphalt can be monitored by utilizing the temperature sensor 18, the temperature of the asphalt can be displayed on a display screen on a controller 37, the asphalt is convenient for a worker to watch, in the process of heating the asphalt, the steam inlet pipe 8, the vertical shaft 27 and the horizontal shaft 24 can be controlled to simultaneously rotate by utilizing the meshing transmission of the driving bevel gear 25 and the driven bevel gear 28 and matching with the meshing transmission of the worm 29 and the worm wheel 30, the effect of reducing the speed by utilizing the meshing transmission of the worm 29 and the worm wheel 30 is realized, the rotating speed of the horizontal shaft 24 is smaller than that of the vertical shaft 27, the horizontal shaft 24 drives the cam 23 to slowly rotate, the cam 23 drives the temperature sensor 18 to slowly reciprocate up and down in the rotation process and under the elastic force action of the two springs 19, the annular scraper 22 can scrape off asphalt adhered to the outer surface of the temperature sensor 18 in the process of reciprocating the temperature sensor 18 up and down, the outer surface of the temperature sensor 18 is cleaned, the problem that asphalt is adhered to the outer surface of the temperature sensor 18 for a long time to cause inaccurate monitoring results of asphalt temperature is avoided, the problem that the asphalt is adhered to the surface of the temperature sensor 18 for a long time to cause damage of the asphalt is also avoided, the monitoring results of the asphalt temperature are more accurate, when the asphalt is heated to a proper temperature, the operation of the steam generator 10 and the motor 13 is stopped, a worker pushes the material receiving trolley 36 to the lower part of the material discharging pipe 33, and then the conveying pump 31 and the asphalt flow meter 34 are started to operate, the asphalt in the storage tank 2 is discharged into the material receiving cart 36 through the material suction pipe 32, the conveying pump 31 and the material discharge pipe 33 in sequence, the asphalt volume pumped into the material receiving cart 36 can be measured by the asphalt flow meter 34, so that the weight of the extracted asphalt can be calculated, the asphalt is conveniently weighed and measured, when the asphalt with the required weight is discharged into the material receiving cart, the conveying pump 31 and the asphalt flow meter are stopped, a worker can push the material receiving cart 36 to convey the asphalt to the next processing place, and meanwhile, the content which is not described in detail in the specification belongs to the prior art which is known by professionals in the field.

To sum up can, this can be to pitch flow intelligence weighing device of pitch even heating, can carry out quick effectual heating to pitch, make pitch be heated evenly, improve the heating efficiency to pitch, guarantee that pitch has good mobility, and can control temperature sensor 18 and carry out up-and-down motion, can scrape the cleanness to 18 surface sticky pitch of temperature sensor, avoid pitch to glue for a long time and glue the surface that glues at temperature sensor 18 and lead to the inaccurate to the monitoring result of pitch temperature, still can avoid pitch to glue for a long time and glue 18 surfaces of temperature sensor and cause its damage, the accuracy to pitch temperature monitoring has been improved, and can extract pitch and transport, the convenience carries out automatic weighing measurement to the pitch of extraction.
