Description

Technical Field

[0001] This utility model relates to the field of asphalt constant temperature heating technology, and in particular to a high and low temperature constant temperature water bath. Background Technology

[0002] In the fields of materials science and road engineering, asphalt, as an indispensable building material, requires precise performance testing to ensure project quality. Such performance tests often require asphalt to be tested under specific temperature conditions to accurately simulate its behavior in real-world application scenarios. Therefore, heating the asphalt to a preset and stable temperature constitutes the core step in the entire testing process.

[0003] For a long time, water bath heating has been the preferred method for heating asphalt. Thanks to water's excellent thermal conductivity and temperature stability, it can create a uniform and easily controllable heating environment for asphalt. However, traditional water bath heating devices face some inherent challenges in actual operation. In particular, after the water bath is immersed in the heating pool and heated to the required temperature, when opening the water bath to remove the asphalt, operators often need to wait for the water in the pool to dissipate naturally before carefully opening the water bath to prevent water from flowing into the water bath and adhering to the asphalt. This undoubtedly increases the difficulty of operation and brings many inconveniences to the testing work. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides a high and low temperature constant temperature water bath, which can prevent water from falling into the water bath when the sealing cover is opened, thereby improving the convenience of operation.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0006] A high and low temperature constant temperature water bath includes a heating pool, a water bath pot, a sealing cover, and a support rod. The heating pool is connected to an inlet and outlet pipe. A heating plate is provided on the side of the heating pool. The support rod is provided on the heating pool to support the water bath pot. An opening is provided at the top of the water bath pot. A first convex ring and a second convex ring are provided on the outer edge of the opening. The first convex ring and the second convex ring extend outward. The first convex ring is located on the outer periphery of the second convex ring, and the height of the first convex ring is lower than the height of the second convex ring. The sealing cover is provided above the water bath pot. The sealing cover includes an inner cover and an outer cover. The inner cover fits against the side of the first convex ring and the top surface of the second convex ring. The outer cover fits against the side and the top surface of the outer edge of the second convex ring. A sealing gasket is provided at the bottom of the inner cover and the outer cover. A retaining ring with an L-shaped cross-section is provided on the outer periphery of the inner cover.

[0007] Furthermore, the heating plate includes a heating wire, which is electrically connected to an external power source.

[0008] Furthermore, the inner cover and the outer cover are provided with internal threads at their bottom, and the first convex ring and the second convex ring are provided with external threads. The inner cover and the outer cover are connected to the first convex ring and the second convex ring through threaded engagement.

[0009] Furthermore, a support plate is provided inside the water bath, and a first square cylinder is fixed inside the water bath. A plurality of first support spheres are provided inside the first square cylinder, and the support plate is mounted on the first support spheres.

[0010] Furthermore, the bottom of the heating pool is provided with a second square cylinder, and a plurality of second support balls are provided inside the second square cylinder, and the water bath is mounted on the second support balls.

[0011] Furthermore, the bottom of the heating pool is provided on a support leg.

[0012] Furthermore, the inlet and outlet pipes are equipped with valves.

[0013] Furthermore, the inner and outer covers are provided with handles on their tops.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Improved temperature stability and uniformity: Through the synergistic effect of the heating pool, heating plate and water bath, the asphalt in the water bath can be ensured to gradually heat up to the preset value under stable temperature conditions. Constant temperature water bath heating can be achieved regardless of whether it is a high temperature or a low temperature state (such as within the range of 40℃ to 100℃).

[0016] 2. Prevents water droplet contamination: The unique sealing cap design, including the inner and outer caps and their tight fit with the first and second convex rings, along with the use of sealing gaskets, effectively prevents water from entering the water bath during the heating process, avoiding water droplet contamination of the asphalt, ensuring the asphalt remains dry, and providing a reliable guarantee for subsequent performance testing.

[0017] 3. Enhanced ease of operation: When the sealing cover is opened, the water on the outer cover is intercepted by the inner cover and will not drip onto the asphalt in the water bath. At the same time, the L-shaped retaining ring on the outer perimeter of the inner cover further prevents water from dripping, improving the ease of operation and safety. Attached Figure Description

[0024] Example 1

[0025] Please refer to the attached document. Figures 1-2This application provides a high and low temperature constant temperature water bath, including a heating pool 1, a water bath 2, a sealing cover 3, and a support rod 6. The heating pool 1 is connected to an inlet and outlet pipe 21. A heating plate 11 is provided on the side of the heating pool 1. Water is added to the heating pool 1 through the inlet and outlet pipe 21, and the heating plate 11 heats the water, which in turn heats the water bath 2, thereby maintaining the asphalt in the water bath 2 at a stable temperature. The heating plate 11 includes a heating wire, which is electrically connected to an external power source. Power is supplied to the heating wire through the external power source to heat the water in the pool 1, thereby heating the asphalt in the water bath 2. The heating pool 1 is provided with the support rod 6, which supports the water bath 2, placing the water bath 2 in the middle of the heating pool 1. The water bath 2 is separated from the heating plate 1 by water, maintaining a stable temperature inside the water bath 2. The water bath 2 has an opening at the top, through which asphalt to be heated is placed. The outer edge 24 of the opening has a first convex ring 7 and a second convex ring 8, extending outwards. The first convex ring 7 is located on the outer periphery of the second convex ring 8, meaning the diameter of the first convex ring 7 is larger than the diameter of the second convex ring 8, and the height of the first convex ring 7 is lower than the height of the second convex ring 8, creating a three-tiered stepped opening. A sealing cover 3 is located above the water bath 2, comprising an inner cover 4 and an outer cover 5. The inner cover 4 fits against the side of the first convex ring 7 and the top surface of the second convex ring 8, while the outer cover 5 fits against the side of the second convex ring 8 and the top surface of the outer edge 24. A sealing gasket 9 is provided at the bottom of the inner cover 4 and the outer cover 5, sealing the bottom of the inner cover 4 and the outer cover 5 securely to prevent water from entering the water bath 2.

[0026] In use, the asphalt to be heated is placed in a water bath 2, and then the inner cover 4 and outer cover 5 are placed on top of the water bath 2. Water is then added to the heating tank 1 through the inlet and outlet pipes 21. The heating plate 11 heats the water in the heating tank 1, controlling the temperature within the water bath 2 through water bath heating. The asphalt is gradually heated to a preset temperature within a stable range, which can be raised to high or low temperatures, such as 40℃, 50℃, 60℃, 70℃, 80℃, 90℃, or 100℃, for constant temperature water bath heating. During the addition process, while maintaining the seal between the upper sealing cover 3 and the water bath 2, the water can be submerged in the water, ensuring that the water bath 2 is in the water and that the temperature is uniform throughout the water bath 2, reducing temperature differences. To accurately control the water bath heating temperature, a thermometer or similar device can be installed in the heating tank 1 to monitor the temperature in real time, facilitating the adjustment of the heating plate 11's power and thus accurately controlling the temperature within the water bath 2. After the water bath constant temperature heating is completed, the water is drained through the inlet and outlet pipes 21. When the sealing cover 3 is opened, the water dripping from the outer cover 5 will not fall into the water bath 2, but will be intercepted by the inner cover 4, thus keeping the asphalt in the water bath 2 dry, facilitating subsequent performance testing. After opening the inner cover 4, the asphalt in the water bath can be taken out for performance testing. The outer periphery of the inner cover 4 is provided with an L-shaped baffle ring, which intercepts water falling onto the inner cover 4, preventing it from dripping downwards and thus preventing water from falling onto the asphalt in the water bath 2, improving the convenience of operation.

[0027] Specifically, the inner cover 4 and the outer cover 5 are provided with handles 23 on their tops, which are used to operate the inner cover 4 and the outer cover 5, making it convenient to close the inner cover 4 and the outer cover 5 tightly.

[0028] Specifically, the inner cover 4 and the outer cover 5 are provided with internal threads 13 at their bottom, and the first convex ring 7 and the second convex ring 8 are provided with external threads 14. The inner cover 4 and the outer cover 5 are connected to the first convex ring 7 and the second convex ring 8 through threaded engagement, thereby improving the stability of the connection.

[0029] Specifically, the outer periphery of the inner cover 4 is provided with a baffle ring with an L-shaped cross section. When the outer cover 5 is opened, if water droplets fall on the inner cover 4, the water will flow into the baffle ring and be intercepted, preventing water droplets on the inner cover 4 from falling into the water bath 2 and keeping the asphalt in the water bath 2 in a dry state.

[0030] Specifically, a support plate 15 is provided inside the water bath 2, and a first square cylinder 16 is fixed inside the water bath 2. The first square cylinder 16 contains several first supporting spheres 17, and the support plate 15 is mounted on the first supporting spheres 17. The support plate 15 is used to hold the asphalt to be tested and is located in the middle of the water bath 2. During the heating process, water first heats the water bath 2, increasing the temperature inside and thus heating the asphalt material. When the temperature from the water bath 2 is transferred to the support plate 15, it needs to pass through the first square cylinder 16 and the first supporting spheres 17. Since the first supporting spheres 17 have a spherical structure, the contact between the first supporting spheres 17 and the contact between the first supporting spheres 17 and the first square cylinder 16 are point contacts. This results in a very small heat transfer area, preventing heat from being transferred through the first supporting spheres and the first square cylinder 16 to the asphalt on the support plate 15, thus maintaining the asphalt at a constant temperature.

[0031] Example 2

[0032] join Figures 1-2 The difference between this embodiment and Embodiment 1 is that the support rod 6 includes a second square cylinder 18 and a second support ball 19. The bottom of the heating pool 1 is provided with a second square cylinder 18, and a plurality of second support balls 19 are arranged inside the second square cylinder 18. The water bath 2 is mounted on the second support balls 19. When the temperature of the heating pool 1 is to be transferred to the water bath 2, it needs to pass through the second square cylinder 18 and the second support ball. Since the second support ball has a spherical structure, the contact between the second support balls and the contact between the second support ball and the second square cylinder 18 are point contacts. This makes the heat transfer area very small, thereby preventing the heat from being transferred to the asphalt on the support plate 15 through the second support ball 19 and the second square cylinder 18, and keeping the asphalt at a constant temperature.

[0033] Specifically, the bottom of the heating pool 1 is provided with a support leg 20 to facilitate the placement of the heating pool 1.

[0034] Specifically, the inlet and outlet pipes 21 are equipped with valves 22, which are used to control the flow of water into and out of the heating pool 1 by opening and closing the valves 22.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
