Technical Field

[0001] The utility model relates to the technical field of drug melting point meters, in particular to a uniform heating device for a drug melting point meter. Background Technique

[0002] According to the definition of physical chemistry, the melting point of a substance refers to the temperature at which the substance changes from a solid state to a liquid state. In the field of organic chemistry, melting point determination is a basic means to identify the nature of a substance and one of the important methods for purity determination. Therefore, melting point meters play an important role in the chemical industry and pharmaceutical research and are essential instruments for producing drugs, spices, dyes, and other organic crystalline substances.

[0003] The existing drug melting point meters can only detect the melting point of the substances inside one group of melting point detection bottles in one operation and cannot detect the substances inside multiple groups of melting point detection bottles simultaneously, which undoubtedly increases the detection time and the usage time of the equipment. In addition, the existing drug melting point meters only heat through the heating wire at the bottom, and the heating method is not uniform and comprehensive enough, thus affecting the accuracy of melting point detection.

[0004] Therefore, it is particularly important to design a uniform heating device for a drug melting point meter to change the above technical defects and improve the overall practicability. Content of the Utility Model

A heating plate is arranged on the top of the connection bottom plate. A plurality of heating coils with the same interval are arranged on the top inside the heating plate. Fixed vertical rods are arranged at the middle positions on the left and right sides of the top of the heating plate. A limiting top plate is jointly connected between the tops of the two fixed vertical rods facing each other. Limiting holes are evenly opened inside the limiting top plate. A plurality of support vertical plates are arranged on the top of the heating plate and behind the heating coils. A semi-enclosed heating sleeve with an opening forward is arranged on the front side of the support vertical plate. Heating wires are evenly distributed inside the semi-enclosed heating sleeve. Melting point detection bottles are arranged inside the semi-enclosed heating sleeve.

[0008] As a preferred scheme of the utility model, the operation host is respectively connected with the heating coils and the heating wires through wires, and the connection method is electrical connection.

[0009] As a preferred scheme of the utility model, there are four groups of each of the heating coils, limiting holes, support vertical plates, and semi-enclosed heating sleeves.

[0010] As a preferred solution of the present utility model, a separable structure design is adopted between the semi - enclosed heating sleeve and the melting point detection bottle, and the internal structure size of the semi - enclosed heating sleeve is adapted to the external structure size of the melting point detection bottle.

[0011] As a preferred solution of the present utility model, the mouth of the melting point detection bottle is placed inside the limiting hole, and the bottom of the melting point detection bottle is placed on the top of the heating coil.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, by providing a uniform heating device for a drug melting point instrument, the heating of the heating coil can be controlled according to requirements, and the melting point of substances inside one or more melting point detection bottles can be detected simultaneously, shortening the detection time and improving the detection efficiency. In addition, when placing and using the melting point detection bottle, the melting point detection bottle is placed into the limiting hole of the limiting top plate, so that the mouth of the melting point detection bottle can be fixed, making the heating more stable. At the same time, the melting point detection bottle will also be inserted into the semi - enclosed heating sleeve. During the heating process, not only the heating coil at the bottom heats the bottom of the melting point detection bottle, but also the heating wire inside the semi - enclosed heating sleeve heats the bottle body of the melting point detection bottle.
