Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of constant temperature water bath apparatus for detection of asphalt quality, the body that comprises device, in body, be provided with constant water bath box 2 and energy-accumulating water tank 1, both are connected with return pipe 4 by water inlet pipe 3, on water inlet pipe 3, be provided with water pump 31, water flows into constant water bath box 2 by water inlet pipe 3 from energy-accumulating water tank 1, by return pipe 4, from constant water bath box 2, flow back to energy-accumulating water tank 1, in the present embodiment, two water tanks are the casing of opening above, and are equipped with upper cover, to facilitate water filling and to prevent laboratory sample.Energy-accumulating water tank 1 is provided with heater 5, refrigerating plant 6 and the first temperature sensor 11, the first temperature sensors 11 and is connected with the control end signal of heater 5 and refrigerating plant 6, and heater 5 is a bending-like heating tube 5 that is arranged on energy-accumulating water tank 1 bottom; Refrigerating plant 6 is the air source heat pump system that pipe-coil type evaporator 62, compressor 61, condenser 63, condenser fan 631, capillary 64 and device for drying and filtering 65 form, wherein pipe-coil type evaporator 62 is arranged in energy-accumulating water tank 1, its heat exchanging pipe is along the setting of spiraling of the madial wall of energy-accumulating water tank 1, to increase heat exchange area; In constant water bath box 2, be provided with the second temperature sensor 21, temperature sensor 21 is connected with the control end of water pump 31, and in constant water bath box 2, be also provided with two agitators 22, two agitators 22 are symmetricly set on the two side of constant water bath box 2, to accelerate to enter water and the water in raw water box of constant water bath box 2, carry out heat exchange; On water inlet pipe 3, be also provided with the control valve 32 of controlling discharge size, and the choke valve 42 that is provided with Electromagnetic Control on return pipe 4, choke valve 42 and water pump 31 synchronization actions, be that water pump 31 is to constant water bath box 2 injected water time, the water that the interior temperature of former constant water bath box 2 has not met requirement of experiment is back to energy-accumulating water tank 1 through return pipe 4, the object arranging is like this to reduce the needed water yield in heat exchanging process, and in maintenance experimentation, the water yield is substantially constant.Control for convenience the speed that constant water bath box 2 water temperatures change, on water inlet pipe 3 and be provided with the control valve 32 for regulating pondage.
4 one-tenth diagonal angle settings of water inlet pipe 3 and return pipe of this constant temperature water bath apparatus, return pipe 4 height are higher than water inlet pipe 3, on return pipe, also can not install choke valve additional, but now the experiment water surface elevation of constant water bath box 2 is parallel with the mouth of pipe of return pipe, the water surface elevation of energy-accumulating water tank is lower than the mouth of pipe of return pipe, to avoid two water tanks to carry out heat exchange.After finishing for convenience of experiment, the water in case is discharged, and facilitate this experimental provision to move, in the bottom surface of constant water bath box 2, offer osculum 23, in the bottom surface of energy-accumulating water tank 1, offer osculum 12, and in the bottom surface of device body, one group of universal wheel is installed.
In use, the water temperature in constant water bath box 2 is adjusted to experimental temperature, according to the height of experiment kind and ambient temperature, sets the water temperature in energy-accumulating water tank 1, and make two water tanks keep the larger temperature difference.The constant temperature of 25 ℃ of requirement of experiment for example, ambient temperature is greater than experimental temperature, need the temperature in energy-accumulating water tank to be less than 25 ℃, when the water temperature that measures constant water bath box 2 when the second sensor is greater than 25 ℃, water pump 32 injects the cold water in energy-accumulating water tank 1 in constant water bath box 2, high-temperature water is discharged in energy-accumulating water tank 1 simultaneously, and complete fast heat exchange under the effect of agitator 22, the water temperature of constant water bath box 2 is reduced to 25 ℃.Otherwise, when environment temperature is lower than experimental temperature, or while doing gradually the experiment heating up, need the water temperature of energy-accumulating water tank 1 higher than constant water bath box 2, and utilizing the second temperature sensor 21 to measure and control in real time the water temperature of constant water bath box 2.The first temperature sensor 11 is by measuring the water temperature of energy-accumulating water tank 1, to control heater 5 or refrigerating plant 6 work, keep its with constant water bath box 2 between the larger temperature difference of existence.
