Description

Technical Field

[0001] The utility model relates to a constant temperature water bath device, in particular to an adjustable constant temperature water bath device special for asphalt penetration, belonging to the technical field of constant temperature water bath devices. Background Art

[0002] Asphalt penetration is one of the main quality indicators of asphalt. It is an indicator of the hardness and consistency of asphalt, its ability to resist shear failure, and reflects the relative viscosity of asphalt under certain conditions. The specific regulation is that at 25°C and within 5 seconds, under a load of 100 grams, the depth of vertical penetration of a standard cone into the asphalt sample is the penetration. The asphalt test block used for testing needs to be prepared in advance and cooled and allowed to stand for a period of time. The sample dish containing the sample should be cooled at room temperature of 15°C-30°C for no less than 1.5 hours (small sample dish), 2 hours (large sample dish) or 3 hours (special sample dish), and then moved into a constant temperature water bath device that maintains the specified test temperature of ±0.1°C for no less than 1.5 hours (small sample dish), 2 hours (large sample dish) or 2.5 hours (special sample dish) to ensure that the specimen can meet the test requirements.

[0003] The existing constant temperature water bath device used for insulating asphalt penetration specimens can usually only insulate specimens of one test temperature at the same time. When multiple batches of specimens with different test temperatures are required for experiments, multiple sets of devices are usually required to insulate specimens of different conditions separately. It is impossible to use one device to insulate specimens of multiple conditions at the same time, which is inconvenient to use. Therefore, in response to the above problems, an adjustable constant temperature water bath device specifically for asphalt penetration is proposed. Utility Model Content

[0015] The above structure can realize the circulation of water in the pool body through the operation of the independent circulation pump, thereby ensuring that the temperature of the water in the pool body can be evenly distributed to ensure the effect of water bath heating.

[0016] Furthermore, three mounting grooves are provided above the inner wall of the pool body, and two symmetrically arranged magnet bars are fixedly provided at the bottom of the mounting grooves.

The water bath box 2 includes a box body 21, a heat-insulating plate rack 22 is fixedly provided in the box body 21, and three independent water baths 23 are fixedly provided in the heat-insulating plate rack 22. The circulation pump group 3 includes three independent circulation pumps 31. The independent water baths 23 and their corresponding independent circulation pumps 31 are connected through a circulation water pipe 4. The above-mentioned structural form can use the three independent water baths 23 that work independently of each other to insulate and store test specimens of three different temperature conditions at the same time, and the three independent circulation pumps 31 can respectively pump the heated water in the corresponding independent water baths 23 to ensure uniform water temperature.

[0030] like Figure 3 As shown, the independent water bath 23 includes a pool body 231, and three sets of information nameplates 232 are detachably provided on the upper inner wall of the pool body 231. The information nameplates 232 can record the information of the test pieces at the corresponding positions to avoid confusion when taking them out. In addition, a storage plate 233 is fixedly provided in the pool body 231, and a plurality of symmetrically arranged water through holes 2331 are provided on the storage plate 233. The storage plate 233 can provide the necessary conditions for the placement of the test pieces, and the water through holes 2331 can prevent the storage plate 233 from interfering with the flow of the internal water body.

[0031] like Figure 3 As shown, a temperature sensor 234 is fixedly provided on the inner wall of the pool body 231, and an electric heater 235 is fixedly installed on the upper end surface of the bottom plate of the pool body 231. The temperature sensor 234, the electric heater 235 and the control computer 1 are electrically connected through wires. In the above structural form, the temperature sensor 234 can obtain the current temperature of the water body, and the electric heater 235 can heat the water body by generating heat by itself. The control computer 1 can control the power of the electric heater 235 according to the temperature signal sent back by the temperature sensor 234, thereby regulating the temperature of the heated water body.

[0032] like Figure 1As shown, a cover plate 24 is rotatably provided at the rear of the pool body 231. A rectangular mounting hole is provided on the cover plate 24 and an observation glass 241 is fixedly provided therein. The above-mentioned structural form can flip the cover plate 24 over to cover the box body 21 when the specimen is kept warm. While reducing the degree of heat loss, it can also prevent external foreign matter from entering the device and causing contamination to the water body or the specimen. The observation glass 241 makes it easy for the user to observe the situation inside the device.

The output interface of the independent circulation pump 31 is tightly connected to the water inlet 236 through the circulating water pipe 4, and the input interface of the independent circulation pump 31 is tightly connected to the water outlet 237 through the circulating water pipe 4. The above-mentioned structural form can realize the circulation of water in the pool body 231 through the operation of the independent circulation pump 31, thereby ensuring that the temperature of the water in the pool body 231 can be evenly distributed, so as to ensure the effect of water bath heating.

The control computer 1 can control the power of the electric heater 235 according to the temperature signal sent back by the temperature sensor 234, thereby regulating the temperature of the heated water to ensure that the temperature of the water in the pool body 231 can be kept constant at a predetermined temperature. At the same time, the operation of the independent circulation pump 31 can drive the water in the pool body 231 to circulate, thereby ensuring that the temperature of the water in the pool body 231 can be evenly distributed, so as to ensure the effect of water bath heating.

[0036] Since three independent water baths 23 are provided in the water bath 2 and work independently of each other, specimens of three different temperature conditions can be kept warm at the same time, and three independent circulation pumps 31 can respectively pump the heated water in the corresponding independent water baths 23 to ensure uniform water temperature. In addition, the information nameplate 232 can record the information of the specimen at the corresponding position to avoid confusion when taking it out.
