Description

Technical Field

[0001] This utility model relates to the field of pinacolone synthesis technology, specifically to a pinacolone synthesis feeder. Background Technology

[0002] Pinarone is an important chemical intermediate. Its synthesis process requires high purity of raw materials and high feed accuracy. Solid impurities or particles in the raw materials can easily lead to problems such as reduced reaction efficiency and equipment blockage. Therefore, the raw materials need to be effectively treated before entering the reactor. Existing feeding equipment mostly adopts a single filter structure or manual control of feeding, which makes it difficult to balance filtration efficiency and feeding accuracy. In addition, different raw materials with different properties need to be set up with separate supply devices, which increases the complexity of the equipment and the difficulty of operation.

[0003] In actual production, the filter components of traditional feeders are prone to filtration effect decay due to impurity accumulation, requiring frequent shutdowns for cleaning, which affects production continuity. At the same time, the raw material conveying flow lacks precise measurement, which can easily cause raw material ratio imbalance and lead to fluctuations in the purity of pinacolone products. In addition, some feeding equipment is not designed with an adaptive structure for the flow characteristics of liquid raw materials, resulting in problems such as raw material residue and conveying lag, which restricts the improvement of the stability of the synthesis process. To address these issues, we propose a pinacolone synthesis feeder. Utility Model Content

[0017] Please see Figure 1-6 A pinacol synthesizer feeder, comprising: The feeding base 1 has a support 24 at the top center. The support 24 is a vertical rectangular frame structure, and the top of the feeding base 1 has six flange connection pipes 23 arranged in a ring array.

The bottom of the unfiltered feed elements 7 is connected to the flange connecting pipe 23 by adapter bolts. The unfiltered feed elements 7 can directly supply unfiltered catalysts, which is convenient for subsequent synthesis reactions.

[0018] Furthermore, the top output shaft of the motor 5 is provided with a cam 6, and the cam 6 passes through the top of the support 24. The cam 6 on the top of the motor 5 can make line contact with the shaking impurity filter element 4 of the three filter devices to realize the reciprocating shaking effect of the shaking impurity filter element 4 inside the liquid storage tank 10.

[0019] Furthermore, the filtration device includes a feeder 2, a feed cover 3, and a shaking impurity filter 4. The main body of the filtration device is the feeder 2, and the feeder 2 is provided with a feed cover 3 on its top. The four corners of the bottom of the feed cover 3 are connected to the top of the feeder 2 by matching bolts. The shaker impurity filter 4 is provided inside the feeder 2. The pinacol synthesis solution and reagents to be filtered are injected into the feeder 2 through the top of the feed cover 3. The shaker impurity filter 4 then effectively filters the solution and reagents. The filtered high-precision solution is injected into the pinacol synthesis reactor by the feeder 2 for synthesis.

[0020] Furthermore, the feeder 2 includes a liquid flow meter 8, a pump body 9, and a storage tank 10. The top of the feeder 2 is the storage tank 10, and the bottom of the storage tank 10 is equipped with the pump body 9. The bottom of the pump body 9 is equipped with the liquid flow meter 8, and the bottom of the liquid flow meter 8 is connected to the flange connection pipe 23. The liquid flow meter 8, the pump body 9, and the storage tank 10 are connected in sequence. The filtered high-precision solution is stored at the bottom of the storage tank 1. The pump body 9, in conjunction with the liquid flow meter 8, quantitatively supplies the required solution and reagents to improve the quality of subsequent pinacolone synthesis.

[0021] Furthermore, the storage tank 10 is a hollow rectangular column structure with an open top. The top of the storage tank 10 is provided with a lower liquid groove 11, and two guide slide rods 12 are provided on the two opposite inner walls of the storage tank 10 in an axisymmetrical manner. The shaft ends of the guide slide rods 12 are welded to the side walls of the lower liquid groove 11. The side walls of the storage tank 10 are provided with two sliding holes 13 in an axisymmetrical manner. The storage tank 10 can store the filtered solution and reagents, ensuring a stable subsequent supply and improving the efficiency and quality of production synthesis.

[0022] Furthermore, the vibrating impurity filter element 4 has an inner groove 14 at its top, which corresponds to the lower liquid tank 11. A filter element 19 is located at the center of the bottom of the inner groove 14. Two axially symmetrical sliding holes 15 are provided on the two opposite inner walls of the inner groove 14. The sliding holes 15 are slidably connected to the guide slide rods 12. Two axially symmetrical guide slide rods 16 are welded to the side walls of the vibrating impurity filter element 4. The vibrating impurity filter element 4 is controlled by the cam 6 of the motor 5, which causes its inner groove 14 to move back and forth outside the lower liquid tank 11 to achieve vibration and improve the filtration quality.

[0023] Furthermore, the guide slide rod 16 is slidably connected to the sliding hole 13. The shaft ends of the two guide slide rods 16 are provided with top plates 17, and the side of the top plates 17 facing away from the guide slide rods 16 is in line contact with the cam 6. The top plates 17 are provided with spring members 18 on the side corresponding to the guide slide rods 16. The shaft end of the spring members 18 is in contact with the side wall of the liquid storage tank 10. The spring members 18 are always in a compressed state. Therefore, the top plates 17 and the cam 6 always maintain line contact. The cam 6 can shake the three shaking impurity filter elements 4 to achieve rapid filtration of solution and reagent and improve filtration quality.

[0024] Furthermore, the filter element 19 includes a pre-filter layer 20, a medium-efficiency filter layer 21, and a fine filter layer 22. The top of the filter element 19 is the pre-filter layer 20, the bottom of the pre-filter layer 20 is the medium-efficiency filter layer 21, and the bottom of the medium-efficiency filter layer 21 is the fine filter layer 22. The pre-filter layer 20 is made of a special fiber material with relatively large pores, which can intercept larger impurities in the raw material, prevent large particulate pollutants from entering subsequent filtration stages, reduce the burden on the medium-efficiency filter layer 21 and the fine filter layer 22, and extend the service life of the entire filter structure. The medium-efficiency filter layer 21 uses a finer fiber material or other filter media, and its filtration accuracy is higher than that of the pre-filter layer 20. It can further filter out smaller particles in the raw material and intercept fine particles in the raw material, so that the raw material is further purified. The fine filter layer 22 usually uses high-precision filter materials, such as PTFE membrane filter media, which can capture extremely small particles in the raw material, and even has a high filtration efficiency for some submicron-sized particles, ensuring that the raw materials entering the synthesis reaction have high purity.

[0026] Working principle: The pinacolone synthesis feeder is correctly installed according to the diagram. This feeder achieves graded raw material supply through the filter device on the feed base 1 and the direct feeding assembly. For raw material solutions requiring filtration, the material is injected into the storage tank 10 of the feed component 2 through the feed cover 3, flows from the lower liquid tank 11 to the inner tank 14, and then flows into the inner tank 14 of the vibrating impurity filter component 4. After passing through the pre-filtration layer 20, medium-efficiency filtration layer 21, and fine filtration layer 22 of the filter component 19, multi-stage filtration is completed. The motor 5 drives the cam 6 to rotate, and the cam 6 interacts with the vibrating impurity filter component 4. The top plate 17 of the impurity filter element 4 is in line contact. Under the elastic force of the spring element 18, the impurity filter element 4 vibrates and slides back and forth along the guide slide bar 12 and the guide slide bar 16. The vibration enhances the filtration effect. The filtered liquid flows into the bottom of the storage tank 10. The filtered liquid in the storage tank 10 is drawn by the pump body 9, measured by the liquid flow meter 8, and then transported to the reaction vessel through the flange connection pipe 23. For catalytic reagents that do not require filtration, they are directly supplied through the unfiltered feed element 7 via the flange connection pipe 23, realizing the separate and precise delivery of filtered and unfiltered raw materials.
