Description
Technical field
The utility model relates to a kind of for the liquid such as coal-tar pitch, petroleum pitch being carried out to the asphalt moulding device of cooling curing.
Background technology
Pitch is tar distillation raffinate part, and productive rate accounts for 50%～60% of tar, and it forms by aromatics more than three rings with containing oxygen, nitrogenous, sulfur heterocyclic compound and a small amount of polymer carbon element material.Solid bitumen, as raw material, can be produced anti-corrosion asphalt paint, needle coke or delay coke etc., can also produce as Carbon Materials binding agent and the soaker of use, as Graphite Electrodes, electrolgtic aluminium prebaked anode and cathode paste etc.
Pitch becomes by liquid state the process that solid-state moulding is a change in physical properties, the forming processes of domestic coke-oven plant medium pitch adopts material feeder (blowing funnel) mostly, pitch flows out from the sieve aperture of transport pipe, flow on the drag conveyer of invading in water, the most hollow of the pitch of generation, frangible, water content exceed 5% of international standard regulation.For pitch, its temperature is lower, and viscosity is larger, for ensureing its mobility and avoiding in moulding process producing and stop up, if it keeps comparatively high temps when the moulding of pitch.Because the surface-area of material feeder is larger, under the condition of high temperature, the pitch generation flue gas that can volatilize, causes serious environmental pollution.In addition, in hard pitch moulding process, it is flowed out while falling into the water and can be produced bubble by sieve aperture, and the show bubble that lumps floats on the cooling water surface, and being even adhered on drag conveyer of having is no longer mobile, and needs labor cleaning.When asphalt temperature is low, there will be again feeding pipe, blowing funnel blockade phenomenon.So in whole blowing process, operator will stay scene always.

Further, the scope of described α angle is 15 ° to 30 °; The scope of described θ angle is 0 ° to 60 °.
Further, the number of described nozzle is 6 or 8, and injector spacing is 60mm to 150mm.
Further, the inner chamber of described nozzle is from up to down reducing form, and its inner chamber epimere is conical cavity, and inner chamber hypomere is cylindrical cavity or rectangular cavity.
Further, be arranged between the blind plate sealing flange at described discharge nozzle two ends and discharge nozzle as removably connecting.
The beneficial effects of the utility model are: adopt this asphalt moulding device to replace material feeder molding mode, make technique simple, and easy to operate, solve the problems such as hollow, molded appearance is bad, contained humidity is high.And the requirement of the pitch self-temperature of carrying is reduced, and pitch fall into the water after being penetrated by nozzle, is exposed to the airborne time shorter, and little with air contact surface, the pollution flue gas of generation is little, has improved operating environment.

Embodiment
For ease of understanding technology contents of the present utility model, below in conjunction with accompanying drawing, it is described further.
As depicted in figs. 1 and 2, a kind of asphalt moulding device, comprises copper pipe 4 and multiple nozzle 5 of carrier pipe, discharge nozzle 3, heating use.Described carrier pipe comprises inner tube 1 and is nested with the outer tube 2 outside whole inner tube 1, and described inner tube 1 and outer tube 2 are all L-type.The end of described inner tube 1 section of being arranged vertically is communicated with the discharge port of asphalt delivery pump by flange.The end of described outer tube 2 sections of being arranged vertically is sealed, and on this distolateral wall, steam port A is set.Steam port A is communicated with high-temperature steam source.Putting down to the axis of arranging section of described inner tube 1 and outer tube 2 is parallel to each other and preferably overlaps.Inner tube 1 and outer tube 2 put down to arrange section axis all horizontal by downward-sloping α angle, the scope of described α angle is easily got 15 ° to 30 °.Described inner tube 1 put down to arrange section end, in the axial medium position of described discharge nozzle 3, is communicated with discharge nozzle 3 tube chambers, and described inner tube 1 put down to arrange section axis vertical with the axis of described discharge nozzle 3.Putting down to the end of arranging section of described outer tube 2 is sealed, and the relative steam port A of steam port B(steam port B is set on this distolateral wall, as the vapour outlet of outer tube 2).The two ends of described discharge nozzle 3 all by blind plate sealing flange seal live, between the blind plate sealing flange of setting and discharge nozzle for removably connecting so that cleaning discharge nozzle 3 tube chamber.Described copper pipe 4 is wrapped on the outside surface of described discharge nozzle 3, and one end of described copper pipe 4 connects steam port B(in herein, and steam port B is as the vapor inlet port of copper pipe 4), the other end C is used for the phlegma of exhaust vapour.Described nozzle 5 along described discharge nozzle 3 axially, and centered by the axial centre face of discharge nozzle 3 the symmetrical uniform bottom that is arranged on described discharge nozzle 3 sidewalls.The axis of described nozzle 5 and vertical direction are θ angle, and the scope of described θ angle is 0 ° to 60 °.The number of described nozzle 5 is 6, and nozzle 5 spacing are 60mm to 150mm.Nozzle 5 lower port are apart from the water surface in the scope of 5mm to 10mm, and the carrier bar transport portion after falling into the water for pitch, adopts existing mode, so repeat no more.
As shown in Figure 3, the inner chamber of described nozzle 5 is from up to down reducing form, and its inner chamber epimere is conical cavity, and inner chamber hypomere is cylindrical cavity or rectangular cavity.Footpath, the chamber scope of described nozzle 5 inner chamber hypomeres is 6mm to 12mm, is preferably 8mm or 10mm.
Pitch is pumped in inner tube 1 by transferpump, because putting down between the section of setting and horizontal plane of inner tube 1 exists α angle, flows to discharge nozzle 3 directions so be conducive to pitch.High-temperature steam is passed into by A mouth, flows, and flow in described copper pipe 4 by B mouth at the inner chamber of outer tube 2.High-temperature steam forms and surrounds whole inner tube 1 in the inner chamber of outer tube 2, thereby the pitch in inner tube 1 is heated, and has guaranteed the mobility of pitch.After high-temperature steam enters in copper pipe 4, discharge nozzle 3 is carried out to heating and thermal insulation, guarantee that pitch, interior happy the flowing of discharge nozzle 3, does not stop up.No matter, for inner tube 1 or the heating and thermal insulation of discharge nozzle 3, be the mode of heating in outside, adopt this kind of mode, can suitably reduce the temperature of the pitch pumping into.After pitch enters inner tube 1 and discharge nozzle 3, the inside that is greater than pitch itself with the heating degree of the pitch of tube wall contact position is heated, exist only in tube wall contact position and be adhered, so the temperature of the pitch pumping into is guaranteeing that pitch has proper flow, be mainly adhered by heating is anti-.Moreover under dual setting theing be obliquely installed at pumping pressure and α angle, itself has just had certain promoter action to pitch mobility.
In Fig. 2 (below orientation be as the criterion in defining to change plan, foregoing description is not formed to restriction), be symmetricly set on discharge nozzle 3 left sides, the nozzle 5 of right both sides, the θ angle of vertical direction relatively, be positioned at the nozzle 5 vertical direction inclination relatively left in discharge nozzle 3 left sides, be positioned at the nozzle 5 vertical direction inclination relatively to the right (as the description of above-mentioned " symmetrical uniform setting centered by the axial centre face of discharge nozzle " is expressed) on discharge nozzle 3 right sides, nozzle 5 vergence directions are in the flow direction of just in time having complied with pitch like this, fully ensure the discharging moulding of pitch, avoid nozzle 5 to result in blockage.
Except the technical characterictic described in specification sheets, be the known technology of those skilled in the art.
