[0013] Compared with related technologies, the heating device for pharmaceutical testing and detection provided by the present invention has the following beneficial effects:

[0014] This invention provides a heating device for pharmaceutical testing. A round-bottom flask containing toluene and the drug to be tested is placed inside a heating mantle for heating. The end of a bent moisture measuring tube is connected to the mouth of the round-bottom flask, and a condenser tube is connected to the moisture measuring tube. The heating mantle is activated via a time setting panel, and the temperature is controlled by a temperature control panel. The heating time is set on the time setting panel. Simultaneously, an infrared sensor monitors the connection between the condenser tube and the moisture measuring tube. As water evaporated from the round-bottom flask condenses and drips into the moisture measuring tube through the condenser tube, the infrared sensor receives the signal and sends an electrical signal to the time setting panel. The time setting panel then starts calculating the previously set time. When the set time on the time setting panel returns to zero, an infrared rangefinder at the lower end of the moisture measuring tube detects the moisture level. The toluene inside the moisture measuring tube acts as an obstacle, reflecting the moisture and measuring the height of the water level. The data is then displayed digitally on the data display panel. This device automates the toluene method for determining the moisture content of pharmaceuticals, enhancing experimental controllability, reducing human error, improving research efficiency, and reducing laboratory safety risks.

[0015] This invention provides a heating device for pharmaceutical testing. When installing and fixing a moisture measuring tube, the tube is first passed through the inside of the collar. Then, the screw is rotated to move the clamping plate inside the collar, thereby clamping and fixing the surface of the moisture measuring tube. The same method is used when installing and fixing a condenser tube. Then, the screw at the other end of the connecting rod is turned to make the clamping plate fit against the surface of the fixing frame, thereby achieving clamping. This allows the device to adapt to the use of various measuring tubes of different specifications, effectively improving the adaptability of the device.

[0016] This invention provides a heating device for pharmaceutical testing. By rotating the lead screw and limiting it through the sliding of the limiting rod and the connecting seat, the connecting seat moves vertically on the surface of the lead screw, thereby adjusting the height of the input end of the infrared sensor. This adapts to the position of the connection between the condenser tube and the moisture measuring tube, enabling the input end of the infrared sensor to capture the falling droplets immediately. This further improves the adaptability of the device and increases its accuracy. Attached Figure Description

A moisture measuring tube 19 is inserted into the measuring tube placement port 3. A heating sleeve 28 is installed inside the housing 1 at the lower end of the heating sleeve placement port 31. A round-bottom flask 17 is placed inside the heating sleeve 28. A condenser tube 18 is inserted into the upper end of the moisture measuring tube 19. Both the condenser tube 18 and the moisture measuring tube 19 are fixedly installed on the upper end of the housing 1 by a fixing bracket 2. An infrared rangefinder 29 is provided at the lower end of the moisture measuring tube 19 and is fixedly installed inside the housing 1. An integrated control board is provided at the front end of the housing 1. An installation box 15 is fixedly installed on the side end of the housing 1. The upper end of the installation box 15 is provided with a... The infrared sensor 16 is used for timing. The curved tube of the moisture measuring tube 19 is fitted inside the mouth of the round-bottom flask 17. The integrated control board includes a data display panel 11, a time setting panel 13, and a temperature control panel 14. The data display panel 11 is connected to the output end of the infrared rangefinder 29 through the integrated control board. The time setting panel 13 and the temperature control panel 14 are both connected to the heating jacket 28 through the integrated control board. The infrared sensor 16 is electrically connected to the time setting panel 13. Anti-slip pads 12 are fixedly installed at the four corners of the lower end of the housing 1. The input end of the infrared sensor 16 corresponds to the connection point of the condenser tube 18 and the moisture measuring tube 19. The input end of the infrared rangefinder 29 is perpendicular to the lower end of the moisture measuring tube 19.

[0026] In this embodiment: A round-bottom flask 17 containing toluene and the reagent to be tested is placed inside a heating jacket 28 for heating. Then, the bent end of the moisture measuring tube 19 is connected to the mouth of the round-bottom flask 17, and the condenser tube 18 is connected to the moisture measuring tube 19. The heating jacket 28 is then activated via a time setting panel 13, and the temperature is controlled by a temperature control panel 14. The heating time is set on the time setting panel 13. Simultaneously, an infrared sensor 16 is activated to monitor the connection between the condenser tube 18 and the moisture measuring tube 19. When moisture evaporated from the round-bottom flask 17 condenses through the condenser tube 18 and drips into the moisture measuring tube 19, the infrared sensor detects this. The device 16 receives the signal and sends the electrical signal to the time setting panel 13. At this time, the time setting panel 13 starts the calculation from the previously set time. When the set time of the time setting panel 13 is zeroed, the infrared rangefinder 29 at the lower end of the moisture measuring tube 19 performs infrared sensing. The toluene in the moisture measuring tube 19 acts as an obstacle to reflect the moisture, thereby measuring the height of the moisture in the moisture measuring tube 19 and outputting the data to the data display panel 11 for digital display. This enables the device to automate the toluene method for determining the moisture content of pharmaceuticals, enhances experimental controllability, reduces human error, improves the efficiency of scientific research, and reduces laboratory safety risks.

[0028] Please see Figures 3-4 Based on Embodiment 1, the present invention provides a technical solution: a clamping assembly is provided on the surface of the fixing frame 2, the clamping assembly includes a connecting rod 21, a collar 22 is provided at the end of the connecting rod 21, a clamping plate 23 is attached inside the collar 22, a screw 24 is rotatably mounted on the surface of the clamping plate 23, the screw 24 is threaded through the surface of the collar 22, the clamping assembly is symmetrical about the connecting rod 21, one end of the connecting rod 21 is fastened to the surface of the fixing frame 2, and the back end of the connecting rod 21 is fastened to the condenser tube 18 and the moisture measuring tube 19.

[0029] In this embodiment: when installing and fixing the moisture measuring tube 19, the moisture measuring tube 19 is first passed through the inside of the collar 22, and then the screw 24 is rotated to move the clamping plate 23 inside the collar 22, thereby clamping and fixing the surface of the moisture measuring tube 19. The same method is used when installing and fixing the condenser tube 18. Then, the screw 24 at the other end of the connecting rod 21 is turned to make the clamping plate 23 fit against the surface of the fixing frame 2, thereby achieving clamping. This allows the device to adapt to the use of various measuring tubes of different specifications, effectively improving the adaptability of the device.

[0030] Example 3:

[0031] Please see Figure 3 , Figures 5-6 Based on Embodiment 1, the present invention provides a technical solution: the mounting box 15 has a built-in battery for powering the infrared sensor 16, the upper end of the mounting box 15 is rotatably mounted with a bearing 32, the inner ring of the bearing 32 is fixedly mounted with a lead screw 27, the circumferential surface of the lead screw 27 is threaded through and connected to a connecting seat 26, the back end of the connecting seat 26 slides through and slides on the surface of the limiting rod 25, the lower end of the limiting rod 25 is fixedly mounted on the upper end of the mounting box 15, and the lower end of the infrared sensor 16 is fixedly mounted in the middle part of the connecting seat 26.

[0032] In this embodiment: the rotating lead screw 27 and the limiting action of the through sliding of the limiting rod 25 and the connecting seat 26 cause the connecting seat 26 to move vertically on the surface of the lead screw 27, thereby adjusting the height of the input end of the infrared sensor 16, and thus adapting to the position of the connection between the condenser tube 18 and the moisture measuring tube 19, so that the input end of the infrared sensor 16 can capture the falling droplets in the first time, further improving the adaptability of the device and increasing the accuracy of the device.

[0033] Working principle: A round-bottom flask 17 containing toluene and the reagent to be tested is placed inside the heating mantle 28 and awaits heating. Then, the bent end of the moisture measuring tube 19 is connected to the mouth of the round-bottom flask 17, and the condenser tube 18 is connected to the moisture measuring tube 19. The heating mantle 28 is then activated via the time setting panel 13, and the temperature is controlled by the temperature control panel 14. The heating time is set via the time setting panel 13. Simultaneously, the infrared sensor 16 is activated to monitor the connection between the condenser tube 18 and the moisture measuring tube 19, allowing the water evaporating inside the round-bottom flask 17 to reach the target volume. When the toluene condenses and drips from the condenser tube 18 into the moisture measuring tube 19, the infrared sensor 16 receives the signal and sends an electrical signal to the time setting panel 13. At this time, the time setting panel 13 starts calculating the previously set time. When the set time of the time setting panel 13 returns to zero, the infrared rangefinder 29 at the lower end of the moisture measuring tube 19 performs infrared sensing. The toluene inside the moisture measuring tube 19 acts as an obstacle to reflect the moisture, thereby measuring the height of the moisture in the moisture measuring tube 19 and outputting the data to the digital display panel 11. This allows the device to measure the moisture content of the drug. During the determination, the toluene method for moisture content determination is automated, enhancing experimental controllability, reducing human error, improving research efficiency, and minimizing laboratory safety risks. When installing and fixing the moisture measuring tube 19, it is first passed through the collar 22. Then, the screw 24 is rotated to move the clamping plate 23 within the collar 22, thereby clamping and fixing the surface of the moisture measuring tube 19. The same procedure is followed when installing and fixing the condenser tube 18. Then, the screw 24 at the other end of the connecting rod 21 is turned to make the clamping plate 23 fit against the surface of the fixing frame 2, thus achieving clamping. This allows the device to adapt to the use of various measuring tubes of different specifications, effectively improving its adaptability. The limiting effect of rotating the lead screw 27 and the through sliding of the limiting rod 25 and the connecting seat 26 causes the connecting seat 26 to move vertically on the surface of the lead screw 27, thereby adjusting the height of the input end of the infrared sensor 16. This adapts to the position of the connection between the condenser tube 18 and the moisture measuring tube 19, enabling the input end of the infrared sensor 16 to capture the falling droplets immediately, further improving the adaptability of the device and increasing its accuracy.
