Description

Mixing decice for distributing oil of asphalt

The utility model relates to the mixing device that a kind of mixing arrangement, particularly liquid asphalt are joined oily usefulness, and this device comprises a fixing mix still, is provided with rabbling mechanism in the still.

Chinese patent CN2046769U discloses a kind of " vertical rotating ploughshare asphalt mixture mixing machine ", and this machine comprises that a bottom has the mix bucket of winding type heating flue, the bucket end one side is provided with heating furnace, with the diesel engine is that power can drive three ploughshare mixing plants and the outside feeding device in the bucket, this mixing machine is applicable to the material of mix based on solid material, in addition, owing to adopt naked light to heat, be difficult to avoid because of the pitch glance coal that the end causes that is burned pollutes, safety simultaneously is also relatively poor.

Chinese patent CN2032618U also discloses, and a kind of " closed asphalt melting mixing plant " its objective is in order to develop a kind of pollution little, energy consumption is low, suitable northern area boils the asphalt melting mixing plant that is mixed with talcous pitch mastic, this device adopts dual pot body, the bottom having heaters, pannikin body top is provided with agitator, the space that constitutes between two pots of bodies is the container that boils pitch, the shortcoming of this device is, the position temperature that bottom of pot body contacts with flame is higher, be difficult to avoid pitch to stick with paste the end equally, and the smoke pollution that causes thus, and adopt this mode of heating can not control heating-up temperature, often rule of thumb judge and operate, often cause temperature too high, quickened the aging of pitch.

The purpose of this utility model is to avoid above-mentioned deficiency, provides a kind of and can control heating-up temperature, and the pitch that can avoid sticking with paste the end and smoke pollution is joined oily mixing device.

The utility model pitch is joined stirring system that oily mixing device comprises that an insulation still tube, one are made up of reducing motor, power transmission shaft, agitator arm and feed pump, bleeder valve, the fluid level transmitter that can monitor charge pump work is arranged outside the still tube, be provided with the heat-releasing device that inside is full of the flowing heat transfer medium in the tube, the two ends of this heat-releasing device are communicated with the external heat device by the interface of still barrel.

Heater described in the utility model can adopt hot oil heater or water heater heater, also can adopt solar heat collector, above-mentioned heater can be provided with separately, also can fix with the mix still, hold together, in order to adapt to field mobile operation, can replace the power of reducing motor by diesel engine as mixing plant.

Heat-releasing device described in the utility model is a serpentine coil, or is made up of several fin that are provided with separately and can open and close respectively.

The utility model has the advantages that simple in structurely, can avoid mixing device directly to contact, can adjust heating surface area as required, can control heating-up temperature, can not cause and stick with paste the end, smoke pollution and quicken ageing of asphalt because of the bottom asphalt temperature is too high with naked light.

Fig. 1 is that the utility model pitch is joined oily mixing device structural representation.

Fig. 2 is distributing device and heater structural representation.

As shown in Figure 1, the utility model pitch is joined oily mixing device a vertical retort tube 14, three supporting legs 1 are arranged at the bottom, in order to improve heat insulation effect, the sandwich construction that can load heat insulating material in the middle of the still barrel is designed to, be provided with reductor at still tube top and connect motor 10, agitator arm 18 is equipped with in rotating shaft 13 bottoms that are connected with this motor, charge pump 24 is positioned at the still tube outside, be communicated with charging aperture 12 by feeding tube 15, discharging opening 2 is arranged at still tube bottom, for situation in the still tube is monitored, bimetallic thermometer 19 is installed on barrel, thermocouple temperature measurement table 20, in still tube bottom electronic level transmitter 23 is installed, this fluid level transmitter can show liquid level in the still, if different components pitch is dosed in gradation, the height that then can show variant composition pitch simultaneously, and be converted into volume, this fluid level transmitter can be by the open and close of an electronic switch control charge pump 24, and at the outside float level meter 6 that can intuitively reflect liquid level in the still in addition of still tube, heat-releasing device is the serpentine coil 17 that is positioned at still tube middle part, the two ends of this coil pipe link to each other with the interface that is positioned at the still barrel (3,5) respectively.

As shown in Figure 2, heater 26 is communicated with serpentine coil 17 in the still tube by the interface (3,5) of still barrel, is full of the heating tube 27 interior identical heat-conducting mediums with heater 26 in the coil pipe.

During operation, various different labels pitches are given decide adding value input fluid level transmitter 23, open bitumenpump 24, pitch is pumped to still tube 14, when this label pitch input quantity conforms to the predetermined value that gives elder generation's input fluid level transmitter, fluid level transmitter 23 sends signal, charge pump 24 cuts out, change another label pitch, open charge pump 24 again, in the still of various different labels pitches can being packed in proportion successively, it is that EDR-75F type fluid level transmitter is produced in Dalian that the liquid that the utility model adopts produces transmitter, dose solid material as need, can add by the hand-hole 11 on still tube top, as heat transfer medium, start Heat-transfer Oil Pump 25 with conduction oil, high temperature heat conductive oil circulates between mix still and heater, and the asphalt temperature in the still tube is raise gradually, when thermometer (19,20) demonstration reaches the mix temperature, start reducing motor 10 and drive agitator arm 18 rotations, pitch evenly mixes in the still that makes.

Regulate the flame of gas valve, can control the conduction oil temperature, and then can control asphalt temperature or rising in the still, it is constant perhaps to be stabilized in a certain temperature value scope.

Another embodiment of the present utility model is that mixing plant is driven by small diesel engine.

The 3rd embodiment of the present utility model is that asphalt heater is a solar heater, the heat-conducting oil heating case is placed the solar energy collector focal position, promptly constitute a solar energy asphalt heater, this device can be solidified as a whole with the mix still, also can be provided with separately.

The 4th embodiment of the present utility model be described heat-releasing device for the radiator fin that several are separated from each other to be set in the still tube, by the valve of each radiator fin of switch, can regulate the heating surface (area) (HS in the still tube.
