Abstract
The present invention relates to improvement to a kind of asphalt pump oil installation.The present invention is in original oil pumping device, increases the heating tank internal recycling loop that a cover is made up of three energy thresholds and jet pipe etc.In pitch heat-processed, because the stirring and the Circulation in this internal recycle loop can prevent pitch " pot overflows " and catabiosis effectively.The present invention is simple in structure, and repacking is convenient, is not only applicable to various petroleum pitch and coal-tar pitch, also is applicable to the circulation and the heating of other aqueous material.
Description
The present invention relates to a kind of improvement of pitch oil pump, be mainly used in the heating cycle of petroleum pitch and coal-tar pitch, also can be used for the heating and the circulation of other aqueous material.
Pitch need heat earlier during use as the main raw of building the road, and it is aqueous that it is become, owing to contain certain moisture content in the pitch, therefore when heating boiled, the water molecules in the pitch was wrapped up by the pitch oil film after becoming water vapor, formation one is bubble round and round, causes the pot phenomenon of overflowing.This has not only wasted material, and very dangerous.Simultaneously, because the bituminous heat conductivility is relatively poor,, thereby reduced the bituminous quality so often Yin Wendu is too high has produced aging and also do not melt apart from the pitch of thermal source than distal part part near thermal source pitch partly when heating boils.The method that in the past addressed these problems is, slowly heat the way that gradation is added, perhaps inject high pressure air in the heating tank, also take churned mechanically way, other has U.S. Pat 3666244 to disclose a kind of device, be to adorn a siphunculus at the heating tank inner bottom part, this pipe connects a pitch feed pump, feed pump connects two road pitches and supplies with switching arrangement then, this switching arrangement connects a pipe in addition in heating tank top, switching arrangement also is connected to an output tube, this device can make the pitch forced circulation after the heating, makes the interior pitch of heating tank reach the temperature homogeneous as early as possible, to prevent that local superheating produces aging in the heat-processed, but still the problem that unresolved above-mentioned water vapor is wrapped up by oil film promptly can not realize moisture " pot overflows " phenomenon of volatilizing as early as possible and effectively prevent.
Purpose of the present invention is to provide a kind of novel oil pumping device, forms the pump circulation of pitch in heating tank inside, boils in the process and prevents " pot overflows " and aged purpose thereby reach pitch.
Realize that this purpose device is as follows, oil pump 6 is housed in heating tank, the oil-in of oil pump 6 places the heating tank bottom, the oil outlet of oil pump 6 is received T-valve 8 through transition pipeline, a port of T-valve flows out heating tank through oil outlet 11, another port connects jet pipe 9, spray orifice 10 on jet pipe 9 sprays back heating tank with pitch, and simultaneously bubble is broken, water vapor is evaporated from pitch, T-valve makes it be in different working positions by control stick 12 as required, forms different paths, jet pipe 9 is metal tubes of a hollow, is distributed with several spray orifices 10 on the metal tube.
Fig. 1 is one embodiment of the present of invention, and what illustrate is the submerged type oil pumping device.Wherein: 1 electric motor, 2 shaft couplings, 3 supports, 4 sleeve pipes, 5 transmission shafts, 6 oil pumps, 7 oil-ins, 8 T-valve, 9 jet pipes, 10 spray orifices, 11 oil outlets, 12 control sticks.
The present invention is simple in structure, and repacking is convenient, is convenient to promote, be not only applicable to highway division, be applicable to other building trade yet, have forced circulation pitch and break the bubble oil film, the function that water vapor is overflowed can prevent effectively that pitch from boiling aging and " pot overflows " phenomenon in the process.
Claims (1)
1, a kind of Asphalted oil pump to against overflow, be built-in with oil pump at heating tank, the oil-in of oil pump places the heating tank bottom, the oil outlet of oil pump is received T-valve through output tube, a port of T-valve flows out heating tank through oil outlet, another port connects the jet pipe that places in the heating tank, and a control stick is arranged on the T-valve, it is characterized in that being distributed with on the jet pipe several spray orifices.
