Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Heating device of water tank as shown in Figure 1, for concrete mixing and transporting car, particularly, concrete mixing and transporting car comprises chassis and upper dress two large divisions, on load onto and be provided with water tank 2, chassis is provided with silencer, silencer is connected with motor by outlet pipe 11.Heating device of water tank comprises outlet pipe 3 and the return pipe 9 being communicated with water tank 2 respectively, outlet pipe 3 specifically can be arranged at the two ends of water tank 2, between outlet pipe 3 and return pipe 9, be provided with heat exchanging tube 7, heat exchanging tube 7 is arranged on silencer, particularly, silencer is specially silencing apparatus 6, and heat exchanging tube 7 is specially spiral heat exchange tube, and spiral heat exchange tube is sheathed on or is wound on silencing apparatus 6.In addition, on outlet pipe 3 and/or return pipe 9, be also provided with the power unit for pump water.
In technique scheme, heating device of water tank also comprises temperature transducer 1, and temperature transducer 1 is arranged in water tank 2, for measuring in real time the water temperature of water tank 2.Further, heating device of water tank also comprises controller, temperature transducer 1 and power unit are electrically connected to controller respectively, controller is for controlling the unlatching of power unit or closing, particularly, can in controller, preset water temperature range value, temperature transducer 1 is delivered to controller the water temperature in water tank 2 in real time, when water temperature is equal to or higher than the temperature value of setting, controller can send the signal of closing power unit, now, power unit is closed, and need not to the water in water tank 2, heat again.Correspondingly, when water temperature lower than set temperature value time, controller can send the signal of the unit that turns on the power, now, power unit is opened, the water in water tank 2 starts to flow into heat exchanging tubes 7 along outlet pipe 3, heating is by return pipe 9 reflow tanks 2.
In technique scheme, power unit is specially electric water pump 5, in one embodiment, the turnover water pipe of electric water pump 5 is arranged on return pipe 9, electric water pump 5 comprises feed-water end and waterexit end, start after electrodynamic element, the water in water tank 2 enters electric water pump 5 from feed-water end, and pumps from waterexit end.In another kind is implemented, the turnover water pipe of electric water pump 5 can also be arranged in outlet pipe 3, also can play the effect of pump water.It should be noted that, when the quantity of electric water pump 5 is two, 5, two electric water pumps 5 of an electric water pump can also be set respectively in return pipe 9 and outlet pipe 3 can be opened simultaneously or close simultaneously under the effect at controller.
Too fast for the water for cooling in anti-water stopping tube, in one embodiment, can pipe insulating layer 8 be set at return pipe 9 inwalls, can effectively prevent the too fast cooling of water in pipeline.In another kind of embodiment, can pipe insulating layer 8 be set at outlet pipe 3 inwalls.Without doubt, can be simultaneously at outlet pipe 3 with return pipe 9 is interior that pipe insulating layer 8 is set, and this kind of set-up mode heat insulation effect is best.It should be noted that, pipe insulating layer 8 also can be arranged on the outer wall of pipeline, also can play good insulation effect.
In technique scheme, the water flow in blocking-up return pipe 9 and outlet pipe 3 roads, can also arrange valve 4 on return pipe 9 or on outlet pipe 3, and while opening valve 4, the water in pipeline can free-flow, and during throttle down 4, the water in pipeline stops flowing.Without doubt, can on outlet pipe 3 and return pipe 9, valve 4 be set simultaneously, also can serve the same role, reach identical effect.It should be noted that, the structure of valve 4 can be varied, as butterfly valve etc., at this, do not do concrete restriction.
The heating device of water tank of said structure, working principle is as follows:
Concrete mixing and transporting car is in running, engine high-temperature tail gas is discharged through silencing apparatus 6 from outlet pipe 11, amount of heat is provided to the heat exchanging tube 7 being arranged on silencing apparatus 6, water in heat exchanging tube 7 starts to heat up, water temperature in water tank 2 is when presetting value range, under the effect of controller, electric water pump 5 is in opening state, water in heat exchanging tube 7 after heating can flow into water tank 2 through return pipe 9, and so forth, constantly the water in water tank 2 is heated, until the water in water tank 2 reaches after predefined temperature value, electric water pump 5 quits work under the effect of controller.And so forth, remain that water temperature in water tank 2 is in prespecified range.
And in the season of heat, need not the water temperature in water tank 2 be heated, now, can close the valve 4 on pipeline, the water in pipeline stops flowing.In such cases, electric water pump 5 is also in closed condition.
In addition, in comparatively cold winter, during concrete overdrying in concrete mixing and transporting car, can pass through water tank 2, concrete be carried out to scene and add water and compensate.
The heating device of water tank of this structure, first, structure is comparatively simple, takes up room less, and in using process, without outlet pipe 11 or silencer are carried out to any repacking, therefore, user cost is comparatively cheap.Secondly, automaticity is higher, and according to the different water temperatures in water tank 2, controller can open or close electric water pump 5 in real time, starts or stop the water temperature in water tank 2 is heated.Again, in cold winter, during concrete overdrying in concrete mixing and transporting car, can carry out scene by 2 pairs of concrete of water tank and add water and compensate, therefore, use more for convenience.
On the other hand, the present invention also proposes a kind of concrete mixing and transporting car, comprises and is arranged at the water tank 2 of loading onto, and is also provided with heating device of water tank on water tank 2, and particularly, heating device of water tank is heating device of water tank as above.
In technique scheme, for convenience of the water in water tank 2, from outlet pipe 3, flow out, one end of outlet pipe 3 is arranged at water tank 2 bottoms, and meanwhile, for convenience of the water inflow water tank 2 of return pipe 9, return pipe 9 is arranged at the top of water tank 2.
In addition, too fast for preventing that water temperature in water tank 2 from reducing, in water tank 2 or the outer water tank heat-insulation layers 10 that is also provided with of water tank 2, certainly, also can be simultaneously water tank 2 in the outer water tank heat-insulation layers 10 that arranges of water tank 2.
The concrete mixing and transporting car of this structure, water tank 2 high insulating effect, it is convenient to use.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
