Description

Local quick-heating asphalt tank

The utility model belongs to a kind of pitch and stores heating apparatus.

Pitch is the stock of asphalt pavement structure, and its storage and the quality and the cost of heating and being directly connected to asphalt pavement construction are again simultaneously the key factors that causes environment pollution in the construction.How to make heating of pitch rapider, more convenient, more energy-conservation, cleaner, be the big problem of one in highway engineering and the highway maintenance always.The storage and the heating apparatus of current pitch mainly contain: the oil sump of masonry structure stores, and cauldron is heated; Iron big tank stores, canister are heated, its heating mode again the branch directly-heated type be the indirect heating type of carrier with steam, conduction oil.Thermal source mainly contains fire coal, fuel oil, electric heating, solar energy etc.Its base program all is to be preheated to pitch to be imported after flowing in reservoir vessel to heat in the molten device of high temperature to serviceability temperature (general about 170 ℃), coal burning heat-conducting oil is wherein heated and the far infrared electricity heating is more advanced heating mode, in, large-scale pitch field (station) effect is fine.Wherein a fly in the ointment is for less with oil mass, with oil time erratic county and following highway maintenance unit and general engineering building site, owing to the working ability that can not the give full play to device expenditure of construction height that seems, ton pitch processing cost is higher, the available heat utilization rate is lower, the operating maintenance more complicated.

The grass-roots unit and the plain asphalt pavement construction building site of highway maintenance are badly in need of a kind of pitch and are heated fast rapidly at present, and construction and running cost are cheap, and operating maintenance is convenient, and energy conservation does not cause the novel asphalt of environment pollution to store heating apparatus.

Task of the present utility model: providing a kind ofly can provide the storage heating apparatus of hard pitch at any time fast in the mode of lower cost and running cost and compliance with environmental protection requirements.

The solution of this task is: adopt the steel plate rolling welding, the method for bolt is put into storage tank with body of heater (or other thermal source), and fixing partial closure's cover around the body of heater is with preheating with increase temperature two and go on foot the process of merging into.

The fast heated bitumen jar in this part is for monolithic pitch stores heating apparatus.Mainly contain: tank body, being welded by steel plate adds insulation layer, is placed on the bearing by certain top rake by bearing, to reduce remaining pitch.Body of heater is welded into arch by boiler steel, and the furnace roof finned also is coated with far ultrared paint, to accelerate conduction of heat, improves the thermal efficiency, prevents furnace roof slagging scorification distortion.Seal bootr is welded into arch topped sheet asbestos at interval by steel plate, and around body of heater, cover is top-loaded with the superhigh temperature safety valve with bolt, and submersible bitumenpump and outer suction formula oil pump outlet line are housed in the cover.The secondary seal bootr, leaves the gap and enters for pitch around seal bootr with bolt between two seal bootrs and tank body.

The fast heated bitumen jar in this part is when operation, because body of heater (or other thermal source) all places in the storage tank, its heat of distributing can be all by Asphalt Absorption on every side, because the pitch around the body of heater is by partial closure, its heat can not be with a large amount of outwards conduction of the mode of convection current, again because partial closure's cover has protected sheet asbestos, so it is in extraradial heat is controlled in suitable scope.The pitch that radiant heat and flue residue heat melted replenishes the space of the hard pitch that is drawn out of automatically, forms Automatic Cycle.To the pitch heating of secondary enclosed area, heat energy is fully utilized again for heat that partial closure's cover is distributed and flue residue heat.

The superhigh temperature safety valve is opened after pitch surpasses set point of temperature, and pitch generation convection current guarantees that temperature is unlikely too high, and when estimating once to need the pitch amount big, opening the safety-valve heats can play the effect in expansion office envelope district simultaneously.

Accompanying drawing has been represented an embodiment of the present utility model.

Accompanying drawing 1 is the front view of local fast heated bitumen jar.

Accompanying drawing 2 is the A-A sectional drawing of local fast heated bitumen jar.

As shown in Figure 1: (1) pitch tank body, (2) second layer seal bootr, (3) first floor seal bootr, (4) submersible bitumenpump, (5) fin, (6) arch heating furnace, (7) firebreak, (8) bearing, (9) ash hole, (10) exhaust gas recycling tube, (11) chimney (road), (12) oil-in, (13) superhigh temperature safety net, (14) flowline.

Embodiment: long 800 centimetres of pitch tank body (1), 300 centimetres of diameters are welded with 0.8 centimetre steel plate rolling, and the 3 ° of angles that turn forward are installed on the bearing (8).Arch heating furnace (6) in the pitch tank body is high 70 centimetres, wide 100 centimetres, long 160 centimetres, is welded as a whole with tank body.Furnace roof finned (5) also is coated with far ultrared paint.The body of heater rear side has chimney (road) (11), build in the stove firebreak (7) is arranged, body of heater and pitch tank body joint portion have ash hole (9), first floor seal bootr (3) high 95 centimetres, wide 160 centimetres, long 200 centimetres, use bolt around body of heater, cover is top-loaded with superhigh temperature safety valve (13), submersible bitumenpump (4) is housed in the cover and outer suction formula oil pump outlet line (14) second layer seal bootr (2) is high 140 centimetres, wide 200 centimetres, long 250 centimetres.With bolt around the first floor seal bootr, between two seal bootrs crack be 3～5 centimetres best, chimney and oil-feed gap, seal bootr joint portion are 5 centimetres, 3 centimetres in tank body and gap, seal bootr joint portion.Exhaust gas recycling tube (10) towards furnace bottom is arranged in the tank body, and pitch tank body top one side has oil-in (12).

When combustion furnace (or other thermal source) when pitch is heated, partial closure's cover is heated body of heater (or other thermal source) asphalt seal on every side in the mode of cutting off convection current conduction and minimizing radiation conduction, make the very fast rising of temperature, the heat that distribute the high-temperature region is again to pitch preheating on every side, the harmful exhaust of heating and pining in advance producing is sent into the furnace bottom burning by flue gas leading, energy conservation, pollution abatement.

The fast heated bitumen jar in this part can be coal-fired, oil, the electricity also available conduction oil of directly heating heats indirectly, and pitch is heated rapidly, thermal efficiency height, and expenditure of construction is cheap, and operating maintenance makes things convenient for, and does not cause environment pollution.And be suitable for commercialization production, easy for installation, compliance is strong, but monomer operation, but also multiple tank and usefulness are the field devices of building of comparatively ideal small-sized pitch field.
