Description
Technical field
The utility model relates to a kind of pitch truck spreader waste gas utilization device.
Background technique
Pitch truck spreader is extensively incorporated in permeable layers in newly-built and reorganization and expansion road engineering and adhesion coating construction, and thin overlay construction in road maintenance engineering.Pitch truck spreader will after being transported to operating location, generally need to heat pitch in its tank in bituminous pitch storing to its tank body.Current pitch truck spreader, to the heating of pitch in tank, generally adopts built-in conduction oil or external heat-conducting oil furnace to heat two kinds of modes.But this needs additionally to arrange thermal source.In pitch truck spreader, asphalt reperfusion has following two kinds of situations: one be when the filling of spreading job step distance pitch comparatively near or a construction amount is little, the pitch that bituminous mixing plant directly will be heated to 140-200 degree injects pitch truck spreader storage tank.Now because transportation range is comparatively near, vehicle-mounted asphalt heating system only need play insulation effect.Another kind be when the filling of spreading job step distance pitch comparatively far away or a construction amount is larger, the pitch that will be heated to about 100 degree injects pitch truck spreader storage tank.Now because conveying asphalt needed time is longer, and in storage tank, heated bitumen temperature is lower, so this pitch can not be directly used in spreading operation.According to above situation, present applicant proposes new mode of heating, and play the effect of energy saving.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, with low cost, easy to clean, the coefficient of heat transfer are relatively stable, can the pitch truck spreader waste gas utilization device of energy saving.
Technical solution of the present utility model is:
A kind of pitch truck spreader waste gas utilization device, comprise two and half cylindrical shells, two ellipsoidal heads, hollow sleeve, volute, bases, half cylindrical shell, ellipsoidal head are combined by clamping bolt and are arranged on base, it is characterized in that: device is provided with heat conductive oil inlet, conduction oil outlet, inlet exhaust gas, offgas outlet, there is hollow sleeve device inside, hollow sleeve is wound with volute, in volute, has conduction oil.
The material of volute is aluminium or copper.
The utility model has following advantage: 1, structure is simple, and the coefficient of heat transfer is relatively stable; 2, using waste heat from tail gas is utilized, energy saving; 3, this device is dismantled and assembled structure, is convenient to clean inside.
The utility model structure is simple, with low cost, easy to clean, the coefficient of heat transfer are relatively stable, can energy saving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the external structure of the utility model waste gas utilization device.
Fig. 2 is the cut-away view of the utility model waste gas utilization device.
Embodiment
Shown in Fig. 1-2, the meaning representated by number in the figure is: 1, inlet exhaust gas, 2, conduction oil outlet, and 3, half cylindrical shell, 4, clamping bolt, 5, ellipsoidal head, 6, offgas outlet, 7, heat conductive oil inlet, 8, base, 9, hollow sleeve, 10, volute.
A kind of pitch truck spreader waste gas utilization device, comprise two and half cylindrical shells 3, two ellipsoidal heads 5, hollow sleeve 9, volute 10, bases 8, half cylindrical shell 3, ellipsoidal head 5 are combined by clamping bolt 4 and are arranged on base 8, it is characterized in that: device is provided with heat conductive oil inlet 7, conduction oil outlet 2, inlet exhaust gas 1, offgas outlet 6, there is hollow sleeve 9 device inside, hollow sleeve is wound with volute 10, in volute 10, has conduction oil.
Volute adopts aluminum pipe or copper pipe to make.Volute external diameter can be set to 30mm, wall thickness is set to 2.5mm, and length is set to 930mm.Screw diameter is set to 340mm, and the spiral number of turns is set to 20 circles.Bulk shared by volute, half cylindrical shell size is set to 1100mm, and ellipsoidal head size is set to 131mm, and overall dimensions is set to 1362mmX640mmX640mm.
Tail gas waste heat utilizing device is arranged on bottom, pitch truck spreader chassis, due to limited space, must adopt the spiral coil type heat exchanger taking up room little.Metal tube is made helical by this heat exchanger, and be arranged in two circular cylinders, spiral Bottomhole pressure heat carrying agent conduction oil, and flow in annular canister body cavity motor exhaust.The heat exchanging process of motor exhaust and conduction oil is divided into 3 stages; One is that tail gas and volute outer surface carry out heat exchange, and two is that volute outer tube wall and inner tubal wall carry out heat exchange, and three is that volute inner tubal wall and conduction oil carry out heat exchange.
Under the effect of pitch truck spreader Heat-transfer Oil Pump, conduction oil is at volute internal circulation flow, and the conduction oil after intensification carries out heat temperature raising by heat exchange to the pitch in storage tank.
Show the simulation test that this device carries out, asphalt temperature can be promoted 40-60 degree by it in the 60min time, can meet daily construction requirement.
Above-described embodiment is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, other multi-form change or change can also be made on the basis of the above description.All within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc. are all included among protection domain of the present utility model.
