Description

Technical Field

[0001] The utility model relates to the technical field of heating jacket equipment, in particular to a quick-cooling constant-temperature heating jacket. Background Art

[0002] In some synthetic experiment setups, a heating jacket is sometimes needed to heat the round-bottom flask, and the experiment may require rapid cooling, such as when the reaction temperature is overheated during a double-ring resin experiment, when the resin synthesis experiment is completed and other reactants need to be added or diluted, or when an emergency problem occurs in the reaction and the temperature needs to be quickly cooled.

[0003] Traditional heating jackets only have the functions of heating and maintaining a constant temperature. If rapid cooling is required, the traditional method is to directly use a fan, or to disassemble the experimental device one by one and then perform other physical cooling methods. It is also possible that only a short period of rapid cooling is required before continuing to heat up, and the disassembled experimental device needs to be reassembled after cooling.

[0004] The former may have extremely limited cooling efficiency because the amount of reactants only reaches half of the flask and it is buried in the heating jacket. The latter has complicated steps and carries the risk of burns, accidental dropping, or difficulty in close contact under special circumstances.

[0005] Therefore, a quick cooling constant temperature heating jacket was designed, which can achieve rapid cooling through the function of the heating jacket without dismantling the experimental device to solve the above problems. It has practical significance and good application prospects. Summary of the invention

[0006] In order to make up for the above shortcomings, the utility model provides a quick cooling constant temperature heating jacket, which aims to improve the operation that requires rapid cooling in some synthetic experiments. Traditional heating jackets only have the functions of heating and constant temperature. Artificial cooling has the risk of burns, accidental falls, or difficulty in close contact under special circumstances.

[0007] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a quick cooling constant temperature heating sleeve, comprising an outer shell, a first air inlet is provided inside the outer shell, a second air inlet is provided inside the outer shell, a fan is fixedly connected inside the outer shell, an outer wall of the fan is fixedly connected to the inside of the first air inlet, an outer wall of the first air inlet is arranged on the outer wall of the second air inlet, an outer wall of the fan is arranged on the outer wall of the second air inlet, a support column is fixedly connected inside the outer shell, a fixed ring is slidably connected to the outer wall of the support column, an outer wall of the fixed ring is slidably connected to the inside of the outer shell, the outer wall of the support column is arranged on the outer wall of the first air inlet, the outer wall of the support column is arranged on the outer wall of the second air inlet, and a drive assembly is arranged inside the outer shell.

[0008] Furthermore, the driving assembly includes a connecting rod, an outer wall of which is rotatably connected to the inside of the housing, one end of the connecting rod is fixedly connected to a gear, and the other end of the connecting rod is fixedly connected to a disc.

[0009] Furthermore, the outer wall of the disc is rotatably connected to the outer wall of the shell, and the gear is meshed with the support column.

[0010] Furthermore, a toothed plate is fixedly connected to the outer wall of the fixed ring, and the gear is meshed with the toothed plate.

[0011] Further, the outer wall of the gear is rotatably connected to the inside of the shell, and the outer wall of the tooth plate is slidably connected to the inside of the shell.

[0012] Furthermore, the outer wall of the tooth plate is slidably connected to the outer wall of the support column, and a groove is provided inside the outer shell.

[0013] Furthermore, the outer wall of the fixed ring is fixedly connected to a heating sleeve inner shell, and the interior of the heating sleeve inner shell is slidably connected to the outer wall of the support column.

[0014] Furthermore, a round-bottom flask is arranged inside the inner liner of the heating jacket, and the outer wall of the round-bottom flask is arranged inside the outer shell.

[0015] The utility model has the following beneficial effects:

[0016] 1.

[0017] 2. In the utility model, the rapid cooling and precise temperature control of the round-bottom flask are achieved through the joint work of the fan and the inner liner of the heating jacket, thereby achieving the effect of maintaining a constant temperature inside the inner liner of the heating jacket. The role of the fan is not only to provide a constant temperature effect, it can also help to evenly distribute the heat in the inner liner of the heating jacket to avoid local overheating or overcooling. In addition, the air flow generated by the fan can also help transfer heat from the heating element to the round-bottom flask, thereby accelerating the heating speed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a quick cooling constant temperature heating sleeve, comprising a shell 1, a first air inlet 2 is opened inside the shell 1, a second air inlet 3 is opened inside the shell 1, a fan 12 is fixedly connected inside the shell 1, the outer wall of the fan 12 is fixedly connected to the inside of the first air inlet 2, the outer wall of the first air inlet 2 is arranged on the outer wall of the second air inlet 3, the outer wall of the fan 12 is arranged on the outer wall of the second air inlet 3, a support column 8 is fixedly connected inside the shell 1, the outer wall of the support column 8 is slidably connected with a fixed ring 11, the outer wall of the fixed ring 11 is slidably connected to the inside of the shell 1, the outer wall of the support column 8 is arranged on the outer wall of the first air inlet 2, the outer wall of the support column 8 is arranged on the outer wall of the second air inlet 3, and a driving component is arranged inside the shell 1.

[0027] Specifically, when cooling is required, the fan 12 is started, sucking in external air and entering the interior of the shell 1 through the first air inlet 2. The air flows through the interior of the shell 1 and cools the object fixed by the heating sleeve inner liner 9. During the cooling process, the air flow generated by the fan 12 helps to quickly transfer air to the object, thereby achieving rapid cooling. When the temperature of the object reaches the set value, the fan 12 changes its speed so that the air flow through the second air inlet 3 helps to lower the temperature of the object, thereby achieving constant temperature control. The design of the support column 8 and the fixed ring 11 allows the object to be stably placed inside the shell 1 and can be adjusted as needed.

[0028] Reference Figure 4 and Figure 5 The driving assembly includes a connecting rod 5, the outer wall of the connecting rod 5 is rotatably connected to the inside of the shell 1, one end of the connecting rod 5 is fixedly connected to a gear 6, the other end of the connecting rod 5 is fixedly connected to a disc 4, the outer wall of the disc 4 is rotatably connected to the outer wall of the shell 1, the gear 6 is meshed with the support column 8, the outer wall of the fixed ring 11 is fixedly connected to a toothed plate 7, the gear 6 is meshed with the toothed plate 7, the outer wall of the gear 6 is rotatably connected to the inside of the shell 1, the outer wall of the toothed plate 7 is slidably connected to the inside of the shell 1, the outer wall of the toothed plate 7 is slidably connected to the outer wall of the support column 8, a groove 13 is opened inside the shell 1, the outer wall of the fixed ring 11 is fixedly connected to a heating jacket liner 9, the interior of the heating jacket liner 9 is slidably connected to the outer wall of the support column 8, a round-bottom flask 10 is arranged inside the heating jacket liner 9, and the outer wall of the round-bottom flask 10 is arranged inside the shell 1.

[0029] Specifically, when the round-bottom flask 10 needs to be heated, the round-bottom flask 10 is placed in the heating jacket liner 9 and fixed inside the outer shell 1 by a fixed ring 11 and a support column 8. The meshing relationship between the gear 6 and the toothed plate 7 allows the position of the fixed ring 11 to be adjusted by rotating the disk 4, thereby adjusting the position and heating efficiency of the heating jacket liner 9. The heating jacket liner 9 is woven from glass fiber and heating resistance wire and has a certain toughness. The difference from the heating jacket liner 9 on the market is that a circular hole with a radius of 2 cm is hollowed out at the bottom for passing through the support column 8. When sinking through the lifting structure, the support column 8 can be passed through to heat the container. The fan 12 inhales external air through the first air inlet 2 and exhausts air through the second air inlet 3, helping to control the temperature inside the heating jacket liner 9 and achieve rapid heating or cooling.

[0030] Working principle: When it is necessary to use the quick-cooling constant temperature heating jacket, firstly, a lifting structure is formed by the disc 4, the connecting rod 5, the gear 6, the tooth plate 7 and the fixed ring 11. In this structure, the tooth plate 7 and the fixed ring 11 are a whole. The disc 4 and the connecting rod 5 rotate inside the shell 1 to drive the tooth plate 7 and the fixed ring 11 to slide above the support column 8. By fixing the heating jacket liner 9 above the fixed ring 11, the heating jacket liner 9 is driven to move up and down by rotating the disc 4. By rotating the gear 6 clockwise, the tooth plate 7, the fixed ring 11 and the heating jacket liner 9 are driven to move downward. The support column 8 supports the round-bottom flask 10 above. At this moment, the separation of the heating jacket liner 9 and the round-bottom flask 10 is completed. The above four The round-bottom flask 10 is 2L, while the diameter of the 2L four-mouth round-bottom flask 10 on the market is generally 175mm, and the radius of this round-bottom flask 10 is 8.75cm. The above-mentioned heating jacket inner liner 9 is hemispherical with an inner radius of 8.8cm, which can wrap the 2L four-mouth round-bottom flask 10, and the heating jacket inner liner 9 is woven from glass fiber and heating resistance wire, and has a certain toughness. The difference from the heating jacket inner liner 9 on the market is that the bottom is hollowed out with a circular hole with a radius of 2cm for passing through the support column 8, and the support column 8 can be passed through when sinking through the lifting structure. The heating jacket shell 1 has two air inlets to ensure gas flow. A fan 12 is installed inside the shell 1, and the remaining space of the shell 1 is a circuit system such as insulation cotton and wires.
