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 inner loop loop that a cover is made up of three energy thresholds and jet pipe etc.In pitch heating process, because the stirring and the ringing of this interior circulation loop can prevent pitch " pot overflows " and deterioration phenomenon effectively.The present invention is simple in structure, and repacking is convenient, is not only applicable to various petroleum tar and coal tar pitch, also is applicable to the circulation and the heating of other aqueous material.
Description
The present invention relates to improvement to a kind of asphalt pump oil installation.The present invention is mainly used in the heating and the circulation of petroleum tar and coal tar pitch, also can be used for the heating and the circulation of other aqueous material.
Pitch is the main raw material(s) of making pavement of road, also is one of indispensable raw material of other all kinds of civil building engineerings.Pitch is generally solid shape and half shape admittedly under the normal temperature state.When using pitch, must heat pitch, it is aqueous that it is become, and could pump from oil tank.In when construction, also need boil to pitch, slough its moisture content, its viscosity is further reduced, could with the mineral aggregate mixed preparing.
Pitch was being heated when boiling in the past, owing to contain certain moisture content in the pitch, and the surface tension of water molecule is lower than oil molecule.Therefore when heating boiled, the water molecule in the pitch was wrapped up by oil film after becoming water vapor, can not overflow, and formation one is bubble round and round, caused " pot overflows ".So not only wasted pitch, and very dangerous.Simultaneously, because the heat-conducting property of pitch is relatively poor, when heating boiled, often Yin Wendu was too high and produce agingly near thermal source pitch partly, and the pitch of the part far away apart from thermal source also melts.Influenced the quality that boils pitch like this.
The method that in the past addressed these problems is that slowly heating or gradation are added pitch in heating tank, alleviate " pot overflows " phenomenon; Perhaps inject high pressure air in the heating tank, and use churned mechanically method, smash oil film, water vapor is overflowed.But the employing said method has perhaps influenced work efficiency, and perhaps device is complicated, has increased processing cost, can not wide popularization and application.
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, thereby reaches the purpose that prevents " pot overflows " and ageing of asphalt.
Realize that this purpose concrete grammar is, increase circulation loop in the bypass in original oil pumping device, circulation loop is made up of oil pump, three-way valve, injection pipe etc. in this.Oil pump can be installed in outside the heating tank body, can be the submerged type oil pump also, is installed within the heating tank body.
Fig. 1 is one embodiment of the present of invention, and this embodiment is the oil pumping device of submerged type.
Fig. 1 is the anti-oil pumping device schematic representation of diving of submerged type.Among the figure: 1 motor, 2 coupling, 3 supports, 4 sleeve pipes, 5 transmission shafts, 6 oil pumps, 7 filler openings, 8 three-way valve, 9 jet pipes, 10 spray orifices, 11 oil outlets, 12 operating handles.
In conjunction with the embodiments the present invention is further described.Pitch pumps from oil pump 6, is divided into two paths when flowing to three-way valve 8.Article one, flow out heating tank through oil outlet 11; Article one, flow into jet pipe 9, the spray orifice 10 on jet pipe 9 sprays back heating tank.Three-way valve 8 makes it be in different working positions by operating handle 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.
When heating boiled pitch, the operating handle 12 by three-way valve 8 was in three-way valve 8 and connects the inner loop circuit positions, and the pitch in the heating tank is through oil pump 6, pump in three-way valve 8 and the jet pipe 9, by the spray orifice on the jet pipe 9 10, spray into heating tank, formed compulsory interior circulation.When pitch sprays heating tank from the spray orifice 10 on the jet pipe 9, smashed the oil film that is wrapped in the steam outside, water vapor is entered in the air, avoided " pot overflows ".Its effect is similar to the positive drive type mechanical agitation.Because compulsory inner loop effect tends to balance the temperature of each one in the heating tank, prevent the local superheating phenomenon simultaneously, improved the quality that boils pitch.
The present invention is simple in structure, and repacking is convenient, and is easy to utilize. The present invention is not only applicable to highway division, is applicable to other architectural engineering industry yet.
