Description

Technical Field

[0001] This utility model relates to the field of melting point apparatus technology, specifically a melting point apparatus for measuring the physical properties of materials. Background Technology

[0002] The melting point is the temperature at which the solid and liquid states of a pure substance can coexist and reach equilibrium under a certain pressure. At this temperature, the chemical potentials of the substances are equal, meaning there is no energy difference between the solid and liquid phases, and they can be interconverted without changing the total energy of the system. A melting point apparatus is an instrument used to determine the melting point of a substance.

[0003] Existing capillary melting point apparatuses typically heat a heat-conducting liquid in a container using a heating element, then use that liquid to heat the substance in the capillary, and finally measure the temperature of the heat-conducting liquid to determine the melting point. However, current heat-conducting liquids require time to cool down after being heated once, thus wasting experimental time. Therefore, a new type of melting point apparatus for measuring material properties is needed to solve these problems. Utility Model Content

A clamping unit is provided above the heating chamber for clamping the capillary tube. It also includes a lifting unit and a water circulation unit. The lifting unit is used to control the spatial height of the clamping unit. The storage chamber has two water storage spaces inside. The water circulation unit is used to draw the heat-conducting liquid from one of the water storage spaces into the heating chamber and then discharge it into the other water storage space.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] This embodiment provides a melting point apparatus for measuring material properties, mainly to solve the problem that current melting point apparatuses require waiting for the heat transfer fluid to cool down after being heated once, thus wasting experimental time. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation: A melting point apparatus for measuring material properties includes: a storage chamber 1 with a heating chamber 2 fixedly mounted on top; two water storage spaces 9 are provided inside the storage chamber 1, and one of the water storage spaces 9 contains a heat-conducting liquid. In use, the user first pumps the heat-conducting liquid into the heating chamber 2 through a water circulation unit 8, clamps a capillary tube containing an object above the heating chamber 2 using a clamping unit 6, and then controls the height of the clamping unit 6 through a lifting unit 7 to insert the capillary tube into the heat-conducting liquid. The heat-conducting liquid is then heated by a heating unit 3 to heat the substance inside the capillary tube. During the heating process, the device fixedly mounted in the storage chamber 1... The controller 5 on the surface of chamber 1 detects the real-time temperature of the heat transfer fluid through the temperature sensor 4 fixedly installed inside the heating chamber 2. During this process, the user can observe the condition of the substance in the capillary and determine the melting point of the substance. After the detection is completed, the user can use the water circulation unit 8 to pump the heat transfer fluid inside the heating chamber 2 into another water storage space 9, thereby achieving rapid replacement of the heat transfer fluid. The main components of the storage chamber 1 are: a main chamber body 101 with a cover plate 102 slidably inserted at the top, and two water storage spaces 9 are both opened on the inner wall of the main chamber body 101. The heating chamber 2 is fixedly installed on the top of the cover plate 102. It should be noted that: from Figure 3It is not difficult to see that the top of the cover plate 102 is provided with two limiting protrusions, and the surface material is rubber. These protrusions can be inserted into the inner wall of the main chamber 101 (the inner wall of the two water storage spaces 9), thereby achieving the limiting 101 of the cover plate 102 above the main chamber. The main components of the heating unit 3 are: a heating space 301 set in the inner wall of the heating chamber 2, and a heating element 302 set inside the heating space 301. In use, after the user places the heating element 302 inside the heating space 301, the mounting ring 303 fixedly installed on the surface of the heating element 302 is attached to the surface of the heating chamber 2. Several limiting bolts 304 are threaded into the surface of the mounting ring 303, so that the surface of the several limiting bolts 304... All are threaded into the surface of the heating chamber 2, thus limiting the heating wire 302 within the heating space 301. During subsequent use, the user can control the heating wire 302 to heat the interior of the heating space 301 via the controller 5, thereby increasing the temperature inside the heating space 301 and further heating the heat transfer fluid. The main components of the clamping unit 6 are: two torsion springs 601 and two rotating plates 602. The two rotating plates 602 are rotatably connected by the two torsion springs 601. When in use, the user can clamp the capillary tube (a prior art device, typically containing an object for measuring melting point) using the two rotating plates 602. The main components of the lifting unit 7 are... The capillary tube is formed by a lifting groove 701 on the surface of the cover plate 102. A sliding plate 703 is slidably inserted into the inner wall of the lifting groove 701, and a threaded rod 702 is rotatably inserted into the inner wall of the lifting groove 701. In use, the user rotates the threaded rod 702, causing the sliding plate 703 to slide along the inner wall of the lifting groove 701. Simultaneously, two rotating plates 602 are slidably inserted into the inner wall of a limiting groove 704, and each has a limiting edge 705 on its surface (the limiting groove 704 is formed on the surface of the sliding plate 703). Therefore, after the user clamps the capillary tube using the two rotating plates 602, inserts the two rotating plates 602 into the inner wall of the limiting groove 704, and ensures that the two limiting edges 705 are in contact with the surface of the sliding plate 703, thus achieving the desired effect. The capillary tube is positioned below the slide plate 703. The main components of the water circulation unit 8 are: two water pumps 801 fixedly extending through the surface of the cover plate 102; several corrugated pipes 802 fixedly installed at both ends of the two water pumps 801; and two circulation inlets 803 at the top of the main chamber 101, with the other ends of the two corrugated pipes 802 fixedly connected to one end of each of the two circulation inlets 803. Therefore, the user can control the two water pumps 801 via the controller 5 to draw water from one of the water storage spaces 9 into the heating chamber 2 and then draw it from the other water pump 801 into another water storage space 9 (the two water pumps 801 face opposite directions). It should be noted that the heating element 302 is existing technology.It was mentioned in the Chinese utility model patent with the authorized public account number CN 219532985 U, for heating heat-conducting fluid.

[0018] By fixing a heating chamber 2 on the top of the storage chamber 1, the user draws the heat-conducting liquid from one of the water storage spaces 9 into the heating chamber 2 through the water circulation unit 8. The heating unit 3 heats the heat-conducting liquid inside the heating chamber 2. Then, the clamping unit 6 clamps the capillary tube containing the object to be tested. Finally, the lifting unit 7 controls the capillary tube to be inserted into the heating chamber 2. The controller 5 detects the temperature inside the heating chamber 2 through the temperature sensor 4. The user can detect the melting point of the object by combining the temperature of the object inside the capillary tube. After testing one sample, the heating unit 3 is turned off, and the water circulation unit 8 can quickly draw new heat-conducting liquid into the heating chamber 2, achieving rapid cooling of the heat-conducting liquid inside the heating chamber 2 without replacing all the heat-conducting liquid, effectively saving resources.

[0019] By setting two rotating plates 602 inside the limiting groove 704, and rotatably connecting the two rotating plates 602 through two torsion springs 601, the user pinches the two rotating plates 602 during use, thereby clamping the capillary tube (the two torsion springs 601 apply a force to bring the two rotating plates 602 closer to each other). Finally, the two rotating plates 602 are inserted into the limiting groove 704, so that the two limiting edges 705 are in contact with the surface of the slide plate 703, thereby limiting the two rotating plates 602 on the inner wall of the limiting groove 704, that is, stably limiting the capillary tube under the slide plate 703.

[0020] like Figure 4 As shown, in some embodiments, one of the rotating plates 602 has rotating protrusions 11 on both sides, while the other rotating plate 602 has a mounting groove 10 on its surface. The surfaces of the two rotating protrusions 11 are rotatably inserted into the inner walls of the mounting groove 10 on both sides. Since two torsion springs 601 are slidably sleeved on the surfaces of the two rotating protrusions 11, one end of each torsion spring 601 is fixedly installed on both sides of the other rotating plate 602, and the other end is fixedly installed on the surfaces of the two rotating protrusions 11, when the user pinches the two rotating plates 602 and rotates them, the two torsion springs 601 will apply a force that brings the two rotating plates 602 closer together. When the user places the capillary tube between the two rotating plates 602 and releases their hand, the capillary tube can be clamped by the two rotating plates 602.

[0021] The working process of this utility model is as follows: First, the user needs to clamp the capillary tube using two rotating plates 602. After clamping, the two rotating plates 602 are placed on the inner wall of the limiting groove 704, so that the two limiting edges 705 are in contact with the surface of the sliding plate 703. Rotating the threaded rod 702 drives the sliding plate 703 and the capillary tube to rise and fall. Then, the controller 5 controls two water pumps 801 to draw the heat transfer liquid into the interior of the heating chamber 2. The heat transfer liquid is heated by the heating wire 302, thus heating the capillary tube. During this process, the controller 5 will detect the temperature change of the heat transfer liquid through the temperature sensor 4. The user can detect the melting point of the substance by observing the changes in the substance inside the capillary tube (existing equipment such as a magnifying glass can be used for assistance during observation).

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
