Description

Technical Field

[0001] The utility model belongs to the technical field of experimental instruments, and in particular relates to a small-sized pressure reaction kettle. Background Art

[0002] Small pressure reactor is a commonly used instrument for chemical reactions. Its main structure consists of reactor body, reactor cover, agitator, heating and stirring control box and other components.

[0003] In the prior art, most of the reactors used by laboratory personnel are products produced by industrial production reactor manufacturers. The reactor bodies and heating furnaces are relatively bulky and may not be convenient to operate. Moreover, the sealing gaskets of existing laboratory reactors mostly use metal-wound graphite gaskets. Because the gaskets have a relatively high hardness, the reactor body flange generally uses 8-12 bolts and screws to tighten the reactor cover, and a large torque is required to tighten the seal to ensure that there is no air leakage. However, the reactor in the laboratory is characterized by a small amount and multiple reaction operations, and the cover needs to be opened frequently for feeding. The laboratory operator has to use a torque wrench to repeatedly remove the screws and tighten the screws each time. The efficiency is extremely low, which brings great inconvenience to the operation. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a small-sized pressurized reactor which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a small pressurized reactor, including a control console, a heating cylinder is fixedly connected to the control console, and also includes: a high-pressure tank, which is placed in the heating cylinder; a tank cover, which is covered on the high-pressure tank; the high-pressure tank and the tank cover are sealed by a soft high-temperature sealing gasket; a pressure gauge is plugged into the tank cover, and the detection end of the pressure gauge extends into the high-pressure tank, and the tank cover is connected to a proportional unloading valve pipe; a stirring assembly for stirring the material in the high-pressure tank is installed on the tank cover; a first electric telescopic rod is symmetrically fixedly connected to the upper end of the control console and is located on both sides of the heating cylinder; a connecting plate is fixedly connected to the tank cover, and its two ends are respectively fixedly connected to the telescopic ends of the adjacent first electric telescopic rods.

[0006] Furthermore, the heating tube includes a shell, an upper cover and an electric heating element. The shell is fixedly connected to the console, and the upper cover is detachably connected to the shell by bolts. The heating element of the electric heating element is located in the shell, and the control end of the electric heating element is installed on the outer wall of the shell.

[0007] Furthermore, the stirring assembly includes a driving motor and a stirring rod with multiple groups of stirring teeth on the surface. The driving motor is fixedly connected to the tank cover. The stirring rod rotates in the high-pressure tank, and the upper end is fixedly connected to the output end of the driving motor.

[0008] In order to prevent the tank cover from driving the high-pressure tank to move upward through the soft high-temperature sealing gasket, further, two second electric telescopic rods are symmetrically fixedly connected to the two sides of the upper cover through a bracket, and the telescopic ends of the second electric telescopic rods are fixedly connected with semicircular rings, and the outer side of the high-pressure tank near the opening is provided with a circle of annular protrusions used in conjunction with the semicircular rings.

[0009] In order to facilitate lowering the temperature of the outer surfaces of the shell and the upper cover, further, the inner surfaces of the shell and the upper cover are provided with a temperature insulation coating.

[0010] In order to improve the stability of the reactor, further, a non-slip pad is fixedly connected to the bottom of the console.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model uses the first electric telescopic rod, the connecting plate and the soft high-temperature sealing gasket and other components in coordination. Compared with the method of sealing the high-pressure tank and the tank cover with bolts or buckles in the prior art, the reactor can not only ensure the sealing between the high-pressure tank and the tank cover to avoid leakage problems, but also facilitate the experimenters to quickly open the tank cover for adding materials in the middle or unloading after the reaction is completed. The entire opening of the cover only takes a short time, which improves the simplicity of operation and greatly improves the efficiency of operation.

[0012] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3 , a small pressurized reactor comprises a control console 1, to which a heating cylinder 2 is fixedly connected, and further comprises: a high-pressure tank 3, which is placed in the heating cylinder 2; a tank cover 302, which is covered on the high-pressure tank 3; the high-pressure tank 3 and the tank cover 302 are sealed and connected via a soft high-temperature sealing gasket 303; a pressure gauge 306 is plugged into the tank cover 302, and the detection end of the pressure gauge 306 extends into the high-pressure tank 3, and a proportional unloading valve pipe 307 is connected to the tank cover 302; a stirring component for stirring the material in the high-pressure tank 3 is installed on the tank cover 302; a first electric telescopic rod 4 is symmetrically fixedly connected to the upper end of the control console 1 and is located on both sides of the heating cylinder 2; a connecting plate 401 is fixedly connected to the tank cover 302, and its two ends are respectively fixedly connected to the telescopic ends of the adjacent first electric telescopic rods 4.

[0021] The heating tube 2 includes a shell 201, an upper cover 202 and an electric heating element 203. The shell 201 is fixedly connected to the console 1, and the upper cover 202 is detachably connected to the shell 201 by bolts. The heating element of the electric heating element 203 is located in the shell 201, and the control end of the electric heating element 203 is installed on the outer wall of the shell 201.

[0022] The stirring assembly includes a driving motor 304 and a stirring rod 305 with multiple groups of stirring teeth on the surface. The driving motor 304 is fixedly connected to the tank cover 302. The stirring rod 305 rotates in the high-pressure tank 3, and the upper end is fixedly connected to the output end of the driving motor 304.

[0023] When the laboratory experimenter needs to use the pressure reactor to prepare the material under pressure, the heating reactor is first placed on the workbench and its electrical equipment is powered on. Then the experimenter can control the first electric telescopic rod 4 to work through the control console 1, so that the first electric telescopic rod 4 can control the tank cover 302 to open through the connecting plate 401. Then the experimenter can pour the material that needs to be pressurized into the high-pressure tank 3, and then control the tank cover 302 to move down through the first electric telescopic rod 4, so that the tank cover 302 can be opened in the soft The high-pressure tank 3 is sealed under the action of the high-temperature sealing gasket 303, and then the experimenter can control the electric heating element 203 to open through the console 1 to increase the temperature and pressurize the high-pressure tank 3. At the same time, the driving motor 304 is controlled to work through the console 1, so that the driving motor 304 can drive the stirring rod 305 to stir the material to prevent the material from sticking to the bottom and improve the uniformity of heating of the material. When the pressure in the high-pressure tank 3 exceeds a fixed value, the proportional unloading valve pipe 307 will be turned on, so that the high-pressure tank 3 can be depressurized. At the same time, the experimenter can also The pressure in the high-pressure tank 3 can be monitored in real time through the pressure gauge 306. When it is necessary to add materials in the middle of the process of pressurizing the material, or when it is necessary to open the tank cover 302 after the pressurization cooling is completed, the first electric telescopic rod 4 can be controlled to extend again through the control console 1, and then the first electric telescopic rod 4 will drive the tank cover 302 to move up through the connecting plate 401, so that it is separated from the high-pressure tank 3, so that the high-pressure tank 3 can be opened, and then the experimenter can add materials or take the high-pressure tank 3 out of the heating tube 2, take out the finished product after the reaction, and then Through the coordinated use of the first electric telescopic rod 4, the connecting plate 401 and the soft high-temperature sealing gasket 303 and other components, compared with the method of sealing the high-pressure tank 3 and the tank cover 302 by bolts or buckles in the prior art, the reactor can not only ensure the sealing between the high-pressure tank 3 and the tank cover 302 to avoid leakage problems, but also make it convenient for experimenters to quickly open the tank cover 302 to add materials in the middle or unload materials after the reaction is completed. The entire opening of the cover only takes a short time, which improves the simplicity of operation and greatly improves the efficiency of operation.

[0024] It should be noted that in actual use, the experimenter can also install a pressure detector under the connecting plate 401, so that when the connecting plate 401 covers the tank cover 302 on the high-pressure tank 3, the pressure value of the connecting plate 401 and the upper cover 202 on the pressure detector can be used to determine whether the tank cover 302 and the high-pressure tank 3 have been sealed, thereby avoiding excessive or incomplete sealing between the tank cover 302 and the high-pressure tank 3, and effectively ensuring the sealing between the high-pressure tank 3 and the tank cover 302.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 3, a small pressurized reactor is basically the same as Example 1, and further: two second electric telescopic rods 204 are symmetrically fixedly connected to the two sides of the upper cover 202 through a bracket, and the telescopic ends of the second electric telescopic rods 204 are fixedly connected with semicircular rings 205. A circle of annular protrusions 301 used in conjunction with the semicircular rings 205 are arranged on the outer side of the high-pressure tank 3 near the opening. When it is necessary to open the tank cover 302 for mid-way filling or taking, the second electric telescopic rod 204 can control the two semicircular rings 205 to be clamped on the outer side of the high-pressure tank 3 and the upper side of the annular protrusion 301, which can avoid the soft high-temperature sealing gasket 303 from adhering to the high-pressure tank 3 and the tank cover 302. Therefore, when the tank cover 302 is opened, the tank cover 302 drives the high-pressure tank 3 to move upward through the soft high-temperature sealing gasket 303, and falls again, causing damage to the high-pressure tank 3 and splashing of the internal material, effectively ensuring the stability of the high-pressure tank 3 in the heating cylinder 2 when the tank cover 302 is separated from the high-pressure tank 3.

[0027] The inner surfaces of the shell 201 and the upper cover 202 are both provided with a temperature insulation coating. By providing the temperature insulation coating inside the shell 201 and the upper cover 202, the temperature of the outer surfaces of the shell 201 and the upper cover 202 can be reduced, thereby preventing the first electric telescopic rod 4 and the second electric telescopic rod 204 from being damaged due to excessively high ambient temperature. At the same time, it can also prevent the experimenter from being burned by accidentally touching the shell 201 or the upper cover 202, thereby improving the safety of the experimenter.

[0028] The bottom of the console 1 is fixedly connected with an anti-skid pad 101. By arranging the anti-skid pad 101 at the bottom of the console 1, when the experimenter places the reactor on a workbench for use, the friction between the console 1 and the workbench can be increased, thereby improving the stability of the reactor placed on the workbench.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
