Description

Technical Field

[0001] This utility model relates to a sodium lauroyl sarcosinate processing device, and more particularly to a temperature-controlled water bath mechanism based on a sodium lauroyl sarcosinate continuous flow synthesis device. Background Technology

[0002] In the industrial preparation of sodium lauroyl sarcosinate, a temperature-controlled water bath is required to treat it, allowing lauroyl chloride and sodium sarcosinate to undergo a condensation reaction at a constant temperature of 45°C. Based on this, some temperature-controlled water bath devices, similar to those shown in patent 202420574116.5, include a water bath and a spiral-shaped reaction tube. The two ends of the reaction tube extend to the outside of the water bath, forming an inlet and an outlet. During use, the mixture is fed into the reaction tube and flows slowly, while hot water at a specified temperature is poured into the water bath outside the reaction tube, thus achieving water bath heating of the mixture within the reaction tube during its flow. Furthermore, manufacturers can control the water bath time by controlling the flow rate of the mixture or by directly controlling the mixture to remain stagnant, thereby improving the treatment effect of the mixture.

[0003] However, the aforementioned temperature-controlled water bath equipment has a drawback: because the water bath time of the mixture needs to be controlled according to its flow rate, when the water bath time needs to be extended, the flow rate of the mixture in the reaction tube will slow down or even stop. This reduces the mixing effect of the mixture in the reaction tube and can also easily cause temperature inconsistencies between the center and outer layers of the mixture, thus reducing the temperature control effect. Furthermore, the limitations of the water bath environment make it difficult for manufacturers to control the circulation of the mixture within the reaction tube.

[0004] Therefore, existing temperature-controlled water bath equipment cannot achieve the circulation of the mixture within the reaction tube. Utility Model Content

[0005] The purpose of this invention is to provide a temperature-controlled water bath mechanism based on a continuous flow synthesis apparatus for sodium lauroyl sarcosinate. It enables the circulation of the mixture within the reaction tube, thereby improving the reaction efficiency of the mixture.

[0006] The technical solution of this utility model is as follows: A temperature-controlled water bath mechanism based on a continuous flow synthesis device for sodium lauroyl sarcosinate includes a water bath tank. The inner side of the water bath tank forms a water bath chamber, an air chamber, and an electrical chamber. A reaction tube is provided in the water bath chamber. One end of the reaction tube extends into the air chamber and forms a feed pipe. The other end of the reaction tube extends into the electrical chamber and is connected to a return pipe via a circulation pump. One end of the return pipe passes through the water bath chamber and is connected to the feed pipe. The middle of the return pipe is connected to a discharge pipe located in the air chamber. One end of the discharge pipe extends to the outside of the air chamber and forms a discharge port. A first electric ball valve is connected to the feed pipe in the air chamber, a second electric ball valve is connected to the discharge pipe in the air chamber, and a third electric ball valve is connected to the return pipe in the air chamber.

[0007] In the aforementioned temperature-controlled water bath mechanism based on the sodium lauroyl sarcosinate continuous flow synthesis device, the water bath outside the reaction tube is filled with temperature-controlled water, and the two sides of the water bath are respectively connected to an inlet pipe and an outlet pipe for circulating and transporting the temperature-controlled water.

[0008] In the aforementioned temperature-controlled water bath mechanism based on the sodium lauroyl sarcosinate continuous flow synthesis device, the exterior of the water bath is covered with a first heat insulation layer.

[0009] In the aforementioned temperature-controlled water bath mechanism based on the sodium lauroyl sarcosinate continuous flow synthesis device, the electrical chamber and the water bath are separated by a partition, and the partition is covered with a second heat insulation layer on the side closer to the electrical chamber.

[0010] In the aforementioned temperature-controlled water bath mechanism based on the sodium lauroyl sarcosinate continuous flow synthesis device, a heat dissipation mesh plate is connected to one side of the electrical chamber, and the first heat insulation layer forms an opening for ventilation at the heat dissipation mesh plate.

[0011] In the aforementioned temperature-controlled water bath mechanism based on the sodium lauroyl sarcosinate continuous flow synthesis device, the water bath and the air chamber are separated from each other by a heat-conducting surface.

[0012] In the aforementioned temperature-controlled water bath mechanism based on the sodium lauroyl sarcosinate continuous flow synthesis device, the heat-conducting surface is connected to a heat-conducting plate on the side near the air chamber, and the end of the heat-conducting plate extends to the feed pipe and the discharge pipe.

[0013] Compared with the prior art, this utility model has the following characteristics: (1) This utility model, through the cooperation of reaction tube, feed tube, return tube, discharge tube and each electric ball valve, enables the mixture to circulate or be discharged outward in the water bath after entering the reaction tube, so that the mixture can flow at a specified flow rate in a constant temperature water bath environment for a specified time, thereby effectively improving the reaction effect of the mixture; on this basis, through the structural limitation of the water bath, the circulation pump and each electric ball valve can be set in the air environment, which facilitates the manufacturer's installation and maintenance. (2) By combining the structure of the heat-conducting surface and the heat-conducting plate, the water bath temperature of the water bath can be used to heat the mixture flowing into the air chamber, thereby improving the temperature control effect of the mixture; furthermore, by combining the structure of the first insulation layer and the second insulation layer, the heat in the water bath and the air chamber can be prevented from dissipating to the electrical room or the external environment, thereby ensuring the working stability of the circulating pump and improving the temperature control effect of this utility model. Therefore, this invention can realize the circulation of the mixture in the reaction tube, thereby improving the reaction effect of the mixture. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example 1. A temperature-controlled water bath mechanism based on a continuous flow synthesis apparatus for sodium lauroyl sarcosinate is configured as follows: Figure 1 As shown, the device includes a water bath 1. Inside the water bath 1, a water bath 101, an air chamber 102, and an electrical chamber 103 are formed. A reaction tube 2 is provided in the water bath 101. One end of the reaction tube 2 extends into the air chamber 102 and forms a feed pipe 3. The other end of the reaction tube 2 extends into the electrical chamber 103 and is connected to a return pipe 5 via a circulation pump 4. One end of the return pipe 5 passes through the water bath 101 and is connected to the feed pipe 3. The middle of the return pipe 5 is connected to a discharge pipe 6 located in the air chamber 102. One end of the discharge pipe 6 extends to the outside of the air chamber 102 and forms a discharge port 7. A first electric ball valve 8 is connected to the feed pipe 3 in the air chamber 102, a second electric ball valve 9 is connected to the discharge pipe 6 in the air chamber 102, and a third electric ball valve 10 is connected to the return pipe 5 in the air chamber 102.

[0018] The water bath 101 is equipped with a first heating tube and a first temperature sensor 11 on its side wall. The first temperature sensor 11 is used to monitor the water bath temperature in the water bath 101. When the water bath temperature is detected to be lower than the threshold, the first heating tube is turned on to heat the temperature-controlled water, thereby ensuring that the temperature of the water bath 101 is kept within the specified range.

[0019] The water bath 101 outside the reaction tube 2 is filled with temperature-controlled water. The water bath 101 is connected to an inlet pipe 12 and an outlet pipe 13 for circulating and transporting the temperature-controlled water on both sides. The inlet pipe 12 and the outlet pipe 13 are located at the bottom and top of the water bath 101, respectively. A manual ball valve for draining water can be installed on one side wall of the water bath 101.

[0020] The water bath chamber 1 is covered with a first heat insulation layer 14.

[0021] The electrical room 103 and the water bath 101 are separated by a partition 15, and the partition 15 is covered with a second heat insulation layer 16 on the side closer to the electrical room 103.

[0022] A heat dissipation mesh plate 17 is detachably connected to one side of the electrical room 103. The first heat insulation layer 14 forms an opening for ventilation at the heat dissipation mesh plate 17. During operation, the operator can remove the heat dissipation mesh plate 17 and disassemble and repair the circulation pump 4.

[0023] The water bath 101 and the air chamber 102 are separated from each other by a heat-conducting surface 18.

[0024] An operating panel is detachably connected to one side of the air chamber 102. The first heat insulation layer 14 outside the operating panel and the first heat insulation layer 14 outside the water bath 1 are set separately, so that the operator can disassemble and assemble the operating panel separately, thereby facilitating the installation and maintenance of the first electric ball valve 8, the second electric ball valve 9 and the third electric ball valve 10.

[0025] The control panel is equipped with a second heating tube and a second temperature sensor 20. The second temperature sensor 20 is used to monitor the temperature inside the air chamber 102. When the temperature is detected to be lower than the threshold, the second heating tube is turned on to heat the air chamber, thereby keeping the temperature of the air chamber within a specified range, which alleviates the temperature fluctuation of the mixture when it flows through the air chamber.

[0026] In this embodiment, during use, the third electric ball valve 10 is first closed while the first electric ball valve 8 and the second electric ball valve 9 are opened. This allows the mixture after the reaction to be discharged from the outlet 7 under the drive of the circulation pump 4. Simultaneously, the mixture to be reacted enters from the feed pipe 3 and fills the reaction pipe 2 and the return pipe 5. After the mixture has been delivered to the designated location, the first electric ball valve 8 and the second electric ball valve 9 are closed simultaneously while the third electric ball valve 10 is opened. This allows the mixture to circulate along the reaction pipe 2 and the return pipe 5 under the drive of the circulation pump 4, thereby achieving circulation and constant temperature water bath treatment of the mixture within the water bath 101.

[0027] During the processing of the mixture, the temperature in the water bath 101 and the air chamber 102 can be regulated by the cooperation of the first temperature sensor 11, the second temperature sensor 20, the first heating tube, and the second heating tube, respectively, thereby ensuring the temperature control effect of the mixture. The cooperation of the second heat insulation layer 16 and the heat dissipation mesh plate 17 can separate the water bath 101 and the electrical chamber 103, thereby preventing the circulation pump 4 from overheating and being damaged, and improving the working stability and service life of the circulation pump 4.

[0028] Example 2. A temperature-controlled water bath mechanism based on a continuous flow synthesis apparatus for sodium lauroyl sarcosinate is configured as follows: Figure 2 As shown, the device includes a water bath 1. Inside the water bath 1, a water bath 101, an air chamber 102, and an electrical chamber 103 are formed. A reaction tube 2 is provided in the water bath 101. One end of the reaction tube 2 extends into the air chamber 102 and forms a feed pipe 3. The other end of the reaction tube 2 extends into the electrical chamber 103 and is connected to a return pipe 5 via a circulation pump 4. One end of the return pipe 5 passes through the water bath 101 and is connected to the feed pipe 3. The middle of the return pipe 5 is connected to a discharge pipe 6 located in the air chamber 102. One end of the discharge pipe 6 extends to the outside of the air chamber 102 and forms a discharge port 7. A first electric ball valve 8 is connected to the feed pipe 3 in the air chamber 102, a second electric ball valve 9 is connected to the discharge pipe 6 in the air chamber 102, and a third electric ball valve 10 is connected to the return pipe 5 in the air chamber 102.

[0029] The water bath 101 is equipped with a first heating tube and a first temperature sensor 11 on its side wall. The first temperature sensor 11 is used to monitor the water bath temperature in the water bath 101. When the water bath temperature is detected to be lower than the threshold, the first heating tube is turned on to heat the temperature-controlled water, thereby ensuring that the temperature of the water bath 101 is kept within the specified range.

[0030] The water bath 101 outside the reaction tube 2 is filled with temperature-controlled water. The water bath 101 is connected to an inlet pipe 12 and an outlet pipe 13 for circulating and transporting the temperature-controlled water on both sides. The inlet pipe 12 and the outlet pipe 13 are located at the bottom and top of the water bath 101, respectively. A manual ball valve for draining water can be installed on one side wall of the water bath 101.

[0031] The water bath chamber 1 is covered with a first heat insulation layer 14.

[0032] The electrical room 103 and the water bath 101 are separated by a partition 15, and the partition 15 is covered with a second heat insulation layer 16 on the side closer to the electrical room 103.

[0033] A heat dissipation mesh plate 17 is detachably connected to one side of the electrical room 103. The first heat insulation layer 14 forms an opening for ventilation at the heat dissipation mesh plate 17. During operation, the operator can remove the heat dissipation mesh plate 17 and disassemble and repair the circulation pump 4.

[0034] The water bath 101 and the air chamber 102 are separated from each other by a heat-conducting surface 18.

[0035] The heat-conducting surface 18 is connected to a heat-conducting plate 19 on the side near the air chamber 102, and the end of the heat-conducting plate 19 extends to the side of the feed pipe 3 and the discharge pipe 6.

[0036] An operating panel is detachably connected to one side of the air chamber 102. The first heat insulation layer 14 outside the operating panel and the first heat insulation layer 14 outside the water bath 1 are set separately, so that the operator can disassemble and assemble the operating panel separately, thereby facilitating the installation and maintenance of the first electric ball valve 8, the second electric ball valve 9 and the third electric ball valve 10.

[0037] In this embodiment, the heat-conducting surface 18 and the heat-conducting plate 19 are used to conduct the temperature in the water bath 101 to the air chamber 102, so that the ambient temperature in the air chamber 102 can approach the water bath temperature of the water bath 101, thereby alleviating the temperature fluctuation of the mixture when it flows through the air chamber 102. Compared with the temperature control method of embodiment 1, the second temperature sensor 20 and the second heating tube can be removed, thus reducing the structural complexity and control difficulty of this embodiment.
