Description

Technical Field

[0001] This application relates to the field of reaction flask technology, and in particular to a small-scale heated reaction flask. Background Technology

[0002] Pilot-scale reaction flasks are containers used for small-scale experiments in chemical experiments and chemical research and development. In scientific research and industrial production, it is often necessary to screen and optimize various reaction conditions to obtain the best reaction results. Pilot-scale reaction flasks allow for rapid testing under different conditions, and by comparing the results, the optimal reaction conditions, such as temperature, pH value, catalyst type, and dosage, can be determined. This provides important reference data for subsequent pilot-scale and large-scale production, helping to improve production efficiency, reduce production costs, and improve product quality.

[0003] In related technologies, reaction flasks are usually heated to determine the reaction of reagents at different temperatures, but it is inconvenient for staff to detect the temperature of reagents inside the reaction flasks. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems existing in the prior art by proposing a small-scale heated reaction flask.

[0005] This application can be achieved through the following technical solution: a small-scale heating reaction flask, including a body with several bottle mouths and a stopper for sealing the bottle mouths, and a temperature sensor, wherein the temperature sensor is inserted through the stopper and extends into the body of the flask, and the stopper is provided with a liquid inlet tube extending into the body of the flask.

[0006] In the above technical solution, the liquid participating in the reaction can enter the bottle body through the inlet pipe, and the stopper can seal the bottle mouth. During the heating process of the bottle body, the temperature sensor can detect the temperature of the liquid inside the bottle body so that the staff can know the status of the liquid reaction at different temperatures.

[0007] Furthermore, a vertical tube and an inclined tube are provided at the bottle mouth, the vertical tube and the inclined tube are connected, and the end of the inclined tube away from the vertical tube is lower than the end of the inclined tube close to the vertical tube.

[0008] In the above technical solution, the reaction products can be discharged from the bottle through an inclined tube connected to a vertical tube.

[0009] Furthermore, a raw material tape is wrapped around the outer surface of the vertical tube, and the raw material tape is clamped onto the inner wall of the bottle mouth.

[0010] In the above technical solution, the raw material tape can be made of polytetrafluoroethylene (PTFE), which has advantages such as chemical corrosion resistance and good sealing performance.

[0011] Furthermore, an extension tube connected to the vertical tube is formed on the vertical tube, and the extension tube is provided with a sealing plug that can seal the opening at the end away from the vertical tube.

[0012] In the above technical solution, when it is not necessary to use an extension tube to inject reagents into the bottle, a sealing plug can be used to block the opening at the top of the extension tube.

[0013] Furthermore, it also includes a clamping component, which comprises two hinged semi-circular arc plates. The inner wall of the semi-circular arc plates is provided with a rubber pad one that can contact the vertical tube and a rubber pad two that can contact the outer wall of the bottle mouth. The two semi-circular arc plates are connected by a connecting assembly.

[0014] In the above technical solution, rubber pad one abuts against the vertical tube, rubber pad two abuts against the outer wall of the bottle mouth, and then the two semi-circular plates are connected by a connecting component. At this time, the two rubber pads one and the two rubber pads two have a clamping effect on the vertical tube and the bottle mouth, so that the vertical tube is not easy to detach from the bottle mouth.

[0015] Furthermore, the connecting assembly includes two rings formed one-to-one on a semi-circular plate, a straight rod passing through the two rings, a limiting block formed at the end of the straight rod and capable of abutting against the rings, a slider located at the end of the straight rod away from the limiting block and slidably connected to the straight rod, and a spring that forces the slider to protrude from the side wall in the length direction of the straight rod, wherein the slider is capable of abutting against the rings.

[0016] In the above technical solution, pressing the slider causes it to retract into the straight rod, which then passes through the two rings. The slider is then released, at which point it abuts against the lower surface of the lower ring and the limiting block abuts against the upper surface of the upper ring.

[0017] Furthermore, the slider has an inclined surface formed thereon, and the inner sidewall of the ring can abut against the inclined surface to allow the slider to retract into the straight rod.

[0018] In the above technical solution, when the inner wall of the ring contacts the inclined surface, the slider can automatically retract into the straight rod.

[0019] Furthermore, the bottle is provided with graduation lines.

[0020] In the above technical solution, the graduation lines make it easy for staff to know the amount of liquid in the bottle.

[0021] In summary, this application has the following technical effects: the liquid participating in the reaction can enter the bottle through the inlet pipe, the stopper can seal the bottle opening, and during the heating process of the bottle, the temperature sensor can detect the temperature of the liquid inside the bottle, so that the staff can know the status of the liquid reaction at different temperatures.

[0028] Reference Figure 1 , 2 One embodiment of this application provides a small-scale heating reaction flask, including a flask body 1 and three bottle openings 11 formed on the flask body 1. The bottle openings 11 can be sealed with stoppers 2, and the flask body 1 is marked with graduation lines. Stoppers 2 are installed on the leftmost bottle opening 11 and the rightmost bottle opening 11. An inlet tube 4 for introducing liquid into the flask body 1 is inserted through the stopper 2 of the leftmost bottle opening 11. A temperature sensor 3 is inserted through the stopper 2 of the rightmost bottle opening 11. The temperature sensor 3 is electrically connected to a digital display screen. The temperature sensor 3 converts the detected temperature signal into an electrical signal, and then converts it into a digital signal through an analog-to-digital converter circuit. The digital signal is then displayed in digital form on the digital display screen, so that the operator can know the temperature of the liquid in the flask body 1.

[0029] Reference Figure 1 , 2A vertical tube 5 passes through the central bottle opening 11. An inclined tube 6 is formed on the vertical tube 5, connecting the vertical tube 5 and the inclined tube 6. The inclined tube 6 is angled. Referring to the figure, an extension tube 8, connected to the vertical tube 5, is formed at the upper end of the vertical tube 5. The length direction of the extension tube 8 is consistent with the length direction of the vertical tube 5. The upper end of the extension tube 8 is open, and a sealing plug 9 is installed on the extension tube 8 to seal its upper opening. The end of the inclined tube 6 facing away from the vertical tube 5 is lower than the end of the inclined tube 6 closest to the vertical tube 5. A cup can be placed at the lower end of the inclined tube 6 to collect the reaction products discharged from the inclined tube 6. A raw material tape 7 is wrapped around the bottom end of the vertical tube 5. The raw material tape 7 can be made of polytetrafluoroethylene (PTFE), which has advantages such as chemical corrosion resistance and good sealing performance. The raw material tape 7 can be secured to the inner wall of the bottle opening 11.

[0030] Reference Figure 3 , 4 This embodiment also includes a clamping member 10, which prevents the vertical tube 5 from easily detaching from the bottle mouth 11. The clamping member 10 includes two hinged semi-circular arc plates 101. The inner wall of the semi-circular arc plate 101 is provided with a rubber pad 102 that can abut against the vertical tube 5 and a rubber pad 103 that can abut against the outer wall of the bottle mouth 11. The two semi-circular arc plates 101 are connected by a connecting component 104. The connecting component 104 includes two rings 1041. The two rings 1041 are formed one-to-one on the two semi-circular arc plates 101. When the two semi-circular arc plates 101 are closed, the two rings 1041 are stacked on top of each other. The connecting assembly 104 includes a vertically arranged straight rod 1042 and a limiting block 1043 formed at the top of the straight rod 1042. The limiting block 1043 can abut against the upper surface of the upper ring 1041. A slider 1044 is slidably mounted at the lower end of the straight rod 1042. A spring 1045 is provided inside the straight rod 1042 to force the slider 1044 to protrude beyond the outer side wall of the straight rod 1042 in the length direction. The spring 1045 can be a compression spring. An inclined surface 12 is formed on the slider 1044. When the inner side wall of the ring 1041 contacts the inclined surface 12, the slider 1044 can retract into the straight rod 1042 on its own.
