Description

Technical Field

[0001] This utility model relates to the field of pinacolone production, specifically to a feeding device for pinacolone production with a flow control mechanism. Background Technology

[0002] Pinacolone is an important pharmaceutical intermediate widely used in the production of 16 new drugs, including the anti-HIV drug atazanavir, the anti-cancer drug dabrafenib, and the anti-epileptic drug staefenol. In the petrochemical industry, a mixed olefin of 2-methyl-1-butene and 2-methyl-2-butene can be obtained by separating the C5 component. In the production process of pinacolone, the use of a feeding device can precisely control the input of raw materials, improve production efficiency, ensure production safety, and adapt to different production needs. The feeding device can also reduce the direct contact of operators with hazardous raw materials, reducing occupational health risks. The feeding device usually has good sealing and stability, which can prevent leakage and volatilization of raw materials during the addition process.

[0003] The existing feeding device for pinacolone production lacks a flow control mechanism because it directly feeds and discharges materials. This means that the input speed and amount of raw materials cannot be precisely controlled, leading to uneven input and affecting the uniformity and stability of the chemical reaction. Furthermore, due to the instability of raw material input, it takes longer to reach the required reaction conditions. Therefore, the lack of a flow control mechanism in the feeding device for pinacolone production will have an adverse impact on production stability, production efficiency, safety hazards, and product quality in the long run.

[0004] Therefore, it is necessary to invent a feeding device for pinacol production with a flow control mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for pinacol production with a flow control mechanism. Through an external flow control chamber, a first gear, a second gear, a closed adjusting plate, a metering cylinder, graduation lines, and an electromagnetic control valve, this feeding device for pinacol production incorporates a flow control mechanism. This allows for precise control of the flow rate of raw materials entering the metering cylinder, ensuring accurate raw material proportions during production. Furthermore, the graduation lines on the outside of the metering cylinder visually display the feed amount, facilitating easy monitoring and adjustment by operators. Simultaneously, precise flow control prevents production safety accidents caused by overfeeding or raw material leakage. Therefore, this feeding device for pinacol production with a flow control mechanism not only improves production efficiency... This technology also enhances production safety, optimizes the production process, improves product quality, and saves energy and costs. It addresses the shortcomings of existing feeding devices for pinacolone production, where direct feeding and discharging without a flow control mechanism means the inability to precisely control the input speed and quantity of raw materials. This leads to uneven raw material input, affecting the uniformity and stability of the chemical reaction. Furthermore, the unstable input of raw materials requires a longer time to reach the required reaction conditions. Therefore, long-term use of a feeding device lacking a flow control mechanism will adversely affect production stability, efficiency, safety, and product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for producing pinacol with a flow control mechanism, comprising a feeding box, which is a main body for carrying pinacol for feeding;

It allows for the batch storage of pinacol raw materials in the feed box. According to production requirements, a servo motor drives the first and second gears to mesh and rotate, thereby opening the closed adjustment plate inside the feed pipe.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The feeding device for producing pinacol with a flow control mechanism shown includes a feeding box 1, which is a main body for carrying pinacol for feeding.

[0027] The feeding pipe 11 is located at the bottom of the feed box 1 and is used for the flow of pinacol raw material. An external flow control cavity 12 is provided outside the feeding pipe 11. A servo motor 13 is fixedly installed outside the external flow control cavity 12. A connecting rod 14 is fixedly installed at the output end of the servo motor 13. A first gear 15 is provided outside the connecting rod 14. A second gear 16 is movably connected to one side of the first gear 15. A movable rod 17 is fixedly installed outside the second gear 16. A closed adjustment plate 18 is fixedly installed at one end of the movable rod 17.

[0028] A metering cylinder 19, located at the bottom of the feeding pipe 11, is used for flow control of pinacolone. The metering cylinder 19 has scale lines 20 on its exterior. A discharge pipe 21 is fixedly installed at the bottom of the metering cylinder 19, and an electromagnetic control valve 22 is fixedly installed at the bottom of the discharge pipe 21. A drive controller 23 is located outside the metering cylinder 19, and a volumetric level sensor 24 is fixedly installed at one end of the drive controller 23. Pinacolone raw materials can be stored in batches in the feeding box 1. According to production needs, the first gear 15 is driven by a servo motor 13. The second gear 16 meshes and rotates, thereby opening the closed regulating plate 18 inside the feed pipe 11. The angle of the closed regulating plate 18 in the feed pipe 11 is adjusted so that the raw material for pinacol production enters the metering cylinder 19 at a uniform speed. Then, the scale line 20 of the metering cylinder 19 is observed. When the required flow rate is reached, the closed regulating plate 18 is closed, and the electromagnetic control valve 22 controls the raw material for pinacol production to enter the equipment for production reaction. This combination gives the feeding device for pinacol production a flow control mechanism.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a support frame 2 is fixedly installed on the outside of the feed box 1. An adjustment groove 3 is provided on the outside of the support frame 2, and a fixing gasket 4 is provided on the outside of the adjustment groove 3. A mounting bolt 5 passes through the outside of the fixing gasket 4. Depending on the current pinacol production equipment, the feeding device can be directly installed above the production equipment via the adjustment groove 3 of the support frame 2, without additional fixing or adjustment steps, thus simplifying the installation process and saving installation time and costs. A closed box cover 6 is provided above the feed box 1, and a feed pipe 7 is fixedly installed above the closed box cover 6. The feed pipe 7 is equipped with an external mounting flange 8, which facilitates connection and installation with external pipes. This allows for the batch feeding of raw materials for pinacol production into the feeding device. A fixing bolt 9 passes through the outside of the feed box 1, and a spacer filter 10 is movably connected to one end of the fixing bolt 9. After the raw materials for pinacol production are fed into the feed pipe 7 in batches, the spacer filter 10 located under the feed pipe 7 can filter out impurities and particulate matter in the raw materials, reducing production interruptions or equipment failures caused by impurities in the raw materials, thereby improving production efficiency.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the connecting rod 14 is fixedly connected to the first gear 15, and the first gear 15 is meshed with the second gear 16. The servo motor 13 drives the first gear 15 and the second gear 16 to rotate, thereby opening the closed adjustment plate 18 inside the feeding pipe 11. The angle of the closed adjustment plate 18 in the feeding pipe 11 is adjusted so that the raw material for pinacol production enters the metering cylinder 19 at a uniform speed. The closed adjustment plate 18 is movably connected to the feeding pipe 11, and the metering cylinder 19 is fixedly connected to the feeding pipe 11. The closed adjustment plate 18 has a simple structure and is easy to operate. If a fault occurs, it is convenient for maintenance personnel to carry out timely maintenance without delaying the normal use of the device.

[0031] The working principle of this practical system is as follows: First, based on the current location and installation requirements of the pinacolone production equipment, the feeding device is directly installed above the production equipment via the adjustment groove 3 of the support frame 2, without the need for additional fixing or adjustment steps, thus simplifying the installation process and saving installation time and costs. Then, the feeding pipe 7 is easily connected to an external pipeline via the mounting flange 8, allowing for the batch feeding of pinacolone production raw materials. Next, the external power supply is connected, allowing the pinacolone production raw materials to enter the feeding box 1 through the feeding pipe 7. As the raw materials enter, the feeding process... The spacer filter 10 under pipe 7 can filter out impurities and particulate matter in the raw materials, reducing production interruptions or equipment failures caused by raw material impurities, thereby improving production efficiency. After this preparation is completed, before producing pinacol, the flow rate of the raw materials can be controlled to allow pinacol to enter the production equipment below at a uniform speed. According to production needs, the switch of servo motor 13 is turned on first, and servo motor 13 drives the first gear 15 and the second gear 16 to mesh and rotate, thereby opening the closed adjustment plate 18 inside the feeding pipe 11. The angle of the closed adjustment plate 18 in the feeding pipe 11 is adjusted to allow pinacol to enter the production equipment below at a uniform speed. The raw material for pinacol production enters the metering cylinder 19 at a uniform rate. The scale 20 on the outside of the metering cylinder 19 is then observed. When the required flow rate is reached, the external drive controller 23 also receives the liquid level data from the volumetric liquid level sensor 24 inside the metering cylinder 19. Once the required pinacol level is confirmed, the sealing regulating plate 18 can be closed. Then, the electromagnetic control valve 22 controls the pinacol raw material to flow out again into the production reaction equipment for pinacol production. This gives the pinacol production feeding device a flow control mechanism, allowing for precise control of the raw material flow. The flow rate of the feed into the metering cylinder 19 is controlled to ensure accurate raw material proportioning during the production process. The scale 20 on the outside of the metering cylinder 19 visually displays the feed amount, allowing operators to easily check and adjust it. Precise control of the feed flow rate prevents production safety accidents caused by overfeeding or raw material leakage. After completing the installation and use of the feeding device for pinacol production according to the above operations, turn off the switch of the servo motor 13. If not used for a long period, simply disconnect the external power supply. This completes the operation of the feeding device for pinacol production with a flow control mechanism.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
