Description

Technical Field

[0001] This utility model relates to the field of synthetic equipment technology, and in particular to a high-efficiency synthetic equipment for phenacetin intermediates. Background Technology

[0002] Phenacetin, also known as phenacetin, is an organic compound, a white crystalline powder used for antipyresis and analgesia. The preparation of phenacetin requires the synthesis of intermediates from raw materials, and then the synthesis of the final product from the intermediates.

[0003] Existing high-efficiency synthesis equipment for phenacetin intermediates typically involves feeding raw materials into a reaction vessel for synthesis. However, existing reaction vessels, generally heated only by electric heating mechanisms, suffer from uneven and insufficient heating, resulting in inadequate heating of the raw materials inside the vessel and poor performance. Furthermore, while existing equipment uses a stirring shaft for mixing the raw materials, gaps between the shaft and the vessel's inner wall prevent sufficient mixing of materials at the bottom and near the side walls, further hindering efficiency. Therefore, we propose a high-efficiency synthesis device for phenacetin intermediates. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an efficient synthesis device for phenacetin intermediates.

[0006] Both sides of the tank are provided with outer shells, both of which are arc-shaped, and each of the outer shells has a skirt extending from the end side. The two skirts are fixed together, and when the two skirts are close to each other, an accommodating space is formed between the two outer shells, and the tank is located in this space.

Several vent pipes are installed on the inner side of both annular pipes. One end of each vent pipe extends into the interior of the outer shell.

[0009] A support base is provided at the bottom of the tank. Vertical plates are symmetrically installed on the top of the support base. Each vertical plate is rotatably connected to a connecting shaft on its side. One end of each connecting shaft is fixed to the side of the outer shell.

[0010] Two rotating shafts are rotatably connected to the adjacent surfaces of the two upright plates. A U-shaped rod is connected between the adjacent ends of the two rotating shafts. A connecting rod is rotatably connected to the side of the U-shaped rod. The other end of the connecting rod extends into the U-shaped seat on the side of one of the outer shells, and the connecting rod is rotatably connected to the U-shaped seat.

[0011] One end of one of the shafts is connected to a drive motor via a gearbox, and the drive motor is fixed to one of the upright plates via the gearbox.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-4 A high-efficiency synthesis device for phenacetin intermediates includes a tank 22, with outer shells 11 on both sides of the tank 22. Both outer shells 11 are arc-shaped, and each outer shell 11 has a skirt 23 extending from its end side. The two skirts 23 are fixed together, and when the two skirts 23 are close together, a receiving space is formed between the two outer shells 11. The tank 22 is located in this space. In actual use, the outer shells 11 can wrap around the tank 22 to protect it.

[0028] like Figure 1 As shown, a support base 1 is provided below the tank body 22. Vertical plates 3 are symmetrically installed on the top of the support base 1. Each vertical plate 3 is rotatably connected to a connecting shaft 4 on its side. One end of each connecting shaft 4 is fixed to the side of the outer shell 11. Through the cooperation between the connecting shaft 4 and the outer shell 11, the tank body 22 can be supported and the tank body 22 can be connected to the vertical plate 3.

[0029] like Figure 1 As shown, a control cabinet 25 is installed on the side of one of the upright plates 3. The control cabinet 25 contains a controller, which is one of the following: a control motherboard, a host, or a PLC logic controller.

[0030] like Figure 1 and Figure 3As shown, a top cover 8 is installed on the top of the tank 22, and several feed pipes 13 are installed on the top of the top cover 8. A discharge pipe 21 is installed at the bottom of the tank 22. In actual use, the staff can transport the raw materials into the tank 22 through the feed pipes 13 for processing, and after processing, discharge them through the discharge pipe 21.

[0031] It should be noted that, as Figure 3 As shown, an electrically controlled valve 26 is installed on the side of the discharge pipe 21. The electrically controlled valve 26 is connected to the controller via a wire. The opening and closing of the discharge pipe 21 can be controlled by the electrically controlled valve 26. In this way, when the raw materials in the tank 22 are synthesized and processed, the electrically controlled valve 26 will be closed to prevent the raw materials from leaking. When the synthesis is completed, the controller will control the electrically controlled valve 26 to open and discharge the raw materials in the tank 22.

[0032] like Figure 3 and Figure 4 As shown, each outer shell 11 is equipped with a heating resistance wire 18 on its side, and there is a gap between each heating resistance wire 18 and the side wall of the tank 22. The space between the outer shell 11 and the tank 22 can be heated by the heating resistance wire 18, and the heat will be transferred to the inside of the tank 22, thereby heating the raw materials inside the tank 22.

[0033] It should be noted that, as Figure 3 As shown, the tank 22 has an internal receiving groove 19, and a temperature sensor 20 is installed inside the receiving groove 19. The temperature sensor 20 is connected to the controller via a wire. The temperature sensor 20 can detect the temperature inside the tank 22 and transmit the data to the controller. The controller can then control the heating resistance wire 18 to work as needed, so that the temperature inside the tank 22 is maintained within the preset temperature range, thus improving the performance.

[0034] like Figure 2 and Figure 3As shown, each outer shell 11 and each discharge pipe 21 has a support ring 5 installed on its side. Each support ring 5 has an annular pipe 9 installed on its top. The top of one annular pipe 9 is connected to the air inlet of a circulation pump 7 via an air inlet pipe 6. The circulation pump 7 is fixed to the top of the top cover 8. The air outlet of the circulation pump 7 is connected to an air guide pipe 16. The other end of the air guide pipe 16 is connected to the side of another annular pipe 9. Several vent pipes 17 are installed inside both annular pipes 9. One end of each vent pipe 17 extends into the interior of the outer shell 11, circulating... The circulating pump 7 is connected to the controller via wires. In actual use, when the heating resistance wire 18 is working, the controller will synchronously control the circulating pump 7 to work. The circulating pump 7 draws in air from the top between the outer shell 11 and the tank 22 through the air inlet pipe 6 and the vent pipe 17 and delivers it into the air guide pipe 16. Then, the air is delivered to the bottom between the outer shell 11 and the tank 22 through the lower annular pipe 9 and the vent pipe 17, allowing the air to flow between the outer shell 11 and the tank 22, thereby uniformly heating the inside of the tank 22 and improving the performance.

[0035] like Figure 1 As shown, rotating shafts 24 are rotatably connected to the adjacent surfaces of the two upright plates 3. A U-shaped rod 15 is connected between the adjacent ends of the two rotating shafts 24. A connecting rod 14 is rotatably connected to the side of the U-shaped rod 15. The other end of the connecting rod 14 extends into the U-shaped seat 12 on the side of one of the outer shells 11, and the connecting rod 14 is rotatably connected to the U-shaped seat 12. One end of one of the rotating shafts 24 is connected to a drive motor 2 through a gearbox. The drive motor 2 is fixed to one of the upright plates 3 through the gearbox. The drive motor 2 is connected to the controller through a wire. In actual use, the drive motor 2 will drive the rotating shaft 24 to rotate, which will in turn drive the U-shaped rod 15 to rotate, so that the connecting rod 14 moves with the rotation of the U-shaped rod 15. This controls the tank 22 to swing back and forth along the connecting shaft 4, mixing the raw materials inside the tank 22 thoroughly and improving the usage effect.

[0036] It should be noted that when the shaft 24 rotates, there is a gap between the connecting rod 14 and the annular tube 9 located below, so that when the tank 22 swings, the connecting rod 14 will not collide with the annular tube 9.

[0037] Specifically, in use, the operator feeds the raw materials into the tank 22 through the feed pipe 13. The raw materials then undergo a synthesis reaction within the tank 22. Simultaneously, the controller controls the drive motor 2, which in turn drives the U-shaped rod 15 to rotate via the shaft 24. This, in turn, causes the tank 22 to oscillate along the connecting shaft 4 under the action of the connecting rod 14, mixing the raw materials within the tank 22 to ensure thorough mixing. At the same time, the controller also controls the temperature sensor 20 to detect the temperature within the tank 22 and transmits the detected data to the controller. The controller then controls the heating element as needed. The resistance wire 18 and the circulation pump 7 are working. The heating resistance wire 18 heats the space between the outer shell 11 and the tank 22. At the same time, the circulation pump 7 draws air from the upper part of the space between the outer shell 11 and the tank 22 into the air inlet pipe 6 through the upper vent pipe 17 and delivers it into the air guide pipe 16. Finally, the air flows back to the bottom between the outer shell 11 and the tank 22 through the lower annular pipe 9 and the vent pipe 17, so that the air circulates between the tank 22 and the outer shell 11, which can heat the tank 22 evenly and achieve good heating effect. After the reaction is completed, the controller controls the electric control valve 26 to open and discharge the material in the tank 22 from the discharge pipe 21.

[0038] Furthermore, such as Figure 1 As shown, there is a gap between the bottom of the discharge pipe 21 and the support base 1, so that the discharge pipe 21 will not collide with the support base 1 when the tank 22 swings.

[0039] Furthermore, such as Figure 1 As shown, reinforcing ribs 10 are installed on the sides of both outer shells 11. The reinforcing ribs 10 can strengthen the structure of the outer shells 11 and prevent the outer shells 11 from deforming and being damaged.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
