Abstract
Description
Technical Field
[0001] This invention belongs to the field of chemical equipment technology, specifically a centrifugal extraction machine for the preparation of cyclohexene epoxides. Background Technology
[0002] Epoxy resins and their cured products possess excellent comprehensive properties such as processability, thermal stability, electrical insulation, and UV resistance, and are widely used in aerospace, microelectronics packaging, and motor insulation industries. Aliphatic epoxy compounds can be used to prepare epoxy resins. Because they do not contain residual chlorine or aromatic groups, they exhibit good thermal stability, high weather resistance, and excellent electrical insulation properties. Cyclohexene epoxides serve as important intermediates, and the efficiency of their preparation process and the quality of the resulting products are crucial to the performance and application of the subsequent epoxy resins.
[0003] A Chinese invention patent, CN 119699853 A, discloses a centrifugal extractor. This centrifugal extractor includes a liquid storage container, a drive unit, a filter container, and a water injection container. The drive unit is fixed relative to the liquid storage container. The filter container is disposed within the liquid storage container and driven by the drive unit to extract the material placed in the filter container by centrifugation. The water injection container includes a bottom container fixed relative to the liquid storage container, a middle container with a drain hole, and a sealing valve. The middle container is detachably installed into the bottom container. When the middle container is not installed into the bottom container, the sealing valve closes the drain hole. When the middle container is installed into the bottom container, the sealing valve is driven by the bottom container and opens the drain hole, allowing liquid from the water injection container to enter the filter container.
[0004] However, the above technologies often have the following drawbacks: when applied to the preparation of cyclohexene epoxides, their separation effect is limited by the existing structure and cannot effectively solve the problems of emulsification and incomplete phase separation that may occur during the preparation of cyclohexene epoxides, thus affecting the product yield and purity. In the extraction process, the liquid injection control method is relatively mechanical and it is difficult to accurately adapt to the needs of the reaction condition concentration gradient in the preparation of cyclohexene epoxides.
[0005] Therefore, the present invention provides a centrifugal extraction apparatus for the preparation of cyclohexene epoxides. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A centrifugal extraction machine for preparing cyclohexene epoxides, comprising an outer cavity, an abutment end at the upper end of the outer cavity, a base movably fitted to the upper surface of the abutment end, an inlet on the upper surface of the base, a feed pipe penetrating the inner arc surface of the base, a convex ring sleeved on the top of the outer arc surface of the feed pipe, a light phase channel opened on the outer arc surface of the convex ring, and an upper rotating drum sleeved on the outer arc surface of the convex ring. The upper part is provided with a light phase cavity, the light phase channel, and a conical expansion member is sleeved on the bottom of the feed pipe near the convex ring. The upper end of the conical expansion member is provided with a channel neck, and the bottom end of the conical expansion member is open. A lower drum is placed on the lower surface of the upper drum, and an extraction chamber is provided on the upper end of the lower drum. A sliding drum is sleeved on the bottom of the inner arc surface of the lower drum. There is a gap between the upper drum and the lower drum, and a centrifugal chamber is provided between the upper drum and the lower drum. The sliding drum is sleeved into the centrifugal chamber.
[0008] The tapered expansion member is fitted with a separation component on its outer arc surface near the channel neck. The separation component includes a separation disc fitted on the outer arc surface of the channel neck. The outer arc surface of the separation disc is provided with a guide edge, and the inner arc surface of the separation disc is provided with an upper column.
[0009] The inner arc surface of the upper column is provided with a protrusion, one side of which abuts against the outer arc surface of the channel neck. The top of the outer arc surface of the guide edge is provided with a permeation hole, and the number of permeation holes is several, which are distributed in a ring array on the separation disc.
[0010] A gasket is fitted onto the middle of the upper surface of the separating disc, and the lower surface of the gasket is fitted onto the inner arc surface of the upper column. A spring is fixedly installed on the upper surface of the gasket, and one end of the spring is placed on the inner arc surface of the rotating drum. There are several separating discs, which are longitudinally distributed on the inner arc surface of the centrifuge chamber.
[0011] The upper surface of the sliding drum abuts against the bottom surface of the upper drum and is movably adapted to the gap. The inner arc surface of the sliding drum is provided with a bevel, and there is a gap between the opening at the bottom of the conical expansion member and the inner top wall of the sliding drum.
[0012] Both ends of the arc-shaped segment are provided with bent ends, and an elastic surface is provided between the arc-shaped segment and one of the bent ends, with one side of the elastic surface abutting against the inclined side.
[0013] One side of the bent end has its upper surface placed on the bottom of the separation disc, and the conical outer expansion piece is placed in a concave ring around its periphery. The other side of the bent end has its outer arc surface placed on the inner arc surface of the upper drum, and is in the same plane as the gap.
[0014] The extraction chamber has a sealing end in the middle of the inner arc surface. The extraction chamber is perpendicular to the feed pipe and is adapted to the centrifugal chamber. A stepped section is provided between the extraction chamber and the lower drum. The sliding drum is placed in the inner arc surface of the stepped section.
[0015] The beneficial effects of this invention are as follows: 1. High-efficiency separation and extraction are achieved through the collaborative work of multiple components. The structure of the conical expansion component and the separation disc enables materials to be quickly dispersed and accurately separated. The powerful centrifugal force field generated by the high-speed rotation of the centrifuge chamber, combined with the light phase channel and extraction chamber, ensures that the light and heavy phase materials are quickly separated and enter the corresponding chambers, which significantly shortens the separation time. At the same time, the sealed end of the extraction chamber isolates external interference, and the centrifugal force enhances the mass transfer effect, allowing the heavy phase material to fully contact and react with the extractant. Compared with traditional technology, this significantly improves the extraction efficiency and product yield of cyclohexene epoxides.
[0016] 2. Through the dynamic adjustment structure of the separation discs and springs, the separation gap and effect can be automatically adjusted according to the fluctuations in material flow and pressure, ensuring that efficient and stable separation accuracy can be maintained under different production conditions. The flexible support system formed by the sliding drum and support components can effectively deal with problems such as uneven material distribution and mechanical vibration when the equipment rotates at high speed, ensuring stable equipment operation, optimizing the flow channel environment in the centrifuge chamber, reducing material flow resistance, avoiding problems such as emulsification and incomplete phase separation caused by structural instability, improving product purity, and meeting the requirements of industrial production for equipment stability and reliability.
[0017] 3. By adopting designs such as the movable fit between the contact end and the base, and the cooperation between the sliding drum and the centrifuge chamber, unnecessary complex structures are reduced while ensuring functional integrity. This not only reduces the manufacturing difficulty and cost of the equipment, but also makes the equipment more convenient to maintain and repair, reduces maintenance costs and downtime caused by structural complexity, and improves the overall economic benefits of the equipment.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, this embodiment of the invention includes an outer cavity 1, with an abutment end 11 at the upper end of the outer cavity 1. A base 2 is movably fitted onto the upper surface of the abutment end 11. An inlet 21 is provided on the upper surface of the base 2. A feed pipe 22 is connected through the inner arc surface of the base 2. A protruding ring 221 is sleeved on the top of the outer arc surface of the feed pipe 22. A light phase channel 222 is opened on the outer arc surface of the protruding ring 221. An upper rotating drum 3 is sleeved on the outer arc surface of the protruding ring 221. A light phase cavity 31 is provided at the top of the upper rotating drum 3. The light phase channel 222 and the feed pipe 22 are located near the protruding ring 221. A conical expansion member 4 is fitted to the bottom of the upper drum 3. The upper end of the conical expansion member 4 has a channel neck 41, and the bottom end of the conical expansion member 4 is open. A lower drum 5 is placed on the lower surface of the upper drum 3. An extraction chamber 51 is provided at the upper end of the lower drum 5. A sliding drum 6 is fitted to the bottom of the inner arc surface of the lower drum 5. A gap 7 is provided between the upper drum 3 and the lower drum 5. A centrifugal chamber 8 is provided between the upper drum 3 and the lower drum 5. The sliding drum 6 is fitted into the centrifugal chamber 8. A separation component 9 is fitted to the outer arc surface of the conical expansion member 4 near the channel neck 41. 9 includes a separation disc 91 fitted onto the outer arc surface of the channel neck 41. A guide edge 911 is provided at the edge of the outer arc surface of the separation disc 91. An upper pillar portion 912 is provided in the middle of the inner arc surface of the separation disc 91. A protrusion 913 is provided on the inner arc surface of the upper pillar portion 912. One side of the protrusion 913 abuts against the outer arc surface of the channel neck 41. A permeation hole 914 is formed at the top of the outer arc surface of the guide edge 911. Several permeation holes 914 are arranged in a ring array on the separation disc 91. The upper surface of the separation disc 91... A gasket 92 is fitted onto the upper part of the cylinder 912. The lower surface of the gasket 92 is fitted onto the inner arc surface of the upper column 912. A spring 93 is fixedly installed on the upper surface of the gasket 92. One end of the spring 93 is in the inner arc surface of the upper drum 3. The number of separating discs 91 is several and they are longitudinally distributed in the inner arc surface of the centrifugal cavity 8. The upper surface of the sliding drum 6 abuts against the bottom surface of the upper drum 3 and is movably adapted to the gap 7. The inner arc surface of the sliding drum 6 is provided with a bevel 61. There is a gap between the opening at the bottom of the conical expansion member 4 and the inner top wall of the sliding drum 6.
[0023] First, place the outer cavity 1 in a suitable working position. The abutment end 11 at the upper end of the outer cavity 1 is used to connect with the base 2. Place the base 2 on the abutment end 11 of the outer cavity 1 so that the two fit together. This ensures that the base 2 can be placed stably and is convenient for subsequent operations. On the base 2, the inlet 21 is used for material input. The feed pipe 22 passes through the inner arc surface of the base 2 to introduce the material into the equipment. A convex ring 221 is fitted onto the top of the outer arc surface of the feed pipe 22. The light phase channel 222 on the outer arc surface of the convex ring 221 is used to guide the flow of light phase material. Then, the upper drum 3 is fitted onto the outer arc surface of the convex ring 221. At this time, the light phase cavity 31 at the top of the upper drum 3 is connected to the light phase channel 222 to provide storage space for light phase material. A conical expansion member 4 is fitted onto the bottom of the feed pipe 22 near the bottom of the convex ring 221. The channel neck 41 at the upper end of the conical expansion member 4 is connected to the feed pipe 22. Its open bottom design facilitates the dispersion of material.
[0024] Then, install the separation assembly 9, and fit the separation disc 91 onto the outer arc surface of the channel neck 41. The guide edge 911 on the edge of the outer arc surface of the separation disc 91 helps guide the material flow. The upper column 912 in the middle of the inner arc surface is used to install other components. The protrusion 913 on the inner arc surface of the upper column 912 abuts against the outer arc surface of the channel neck 41, which plays a role in positioning and stabilization. Several permeation holes 914 opened at the top of the outer arc surface of the guide edge 911 are arranged in a ring array to facilitate the passage of materials. A gasket 92 is fitted onto the middle of the upper surface of the separation disc 91. The lower surface of the gasket 92 is fitted into the inner arc surface of the upper column 912, which plays a role in buffering and sealing. A spring 93 is fixedly installed on the upper surface of the gasket 92. The other end of the spring 93 is installed in the inner arc surface of the upper drum 3, so that the separation disc 91 has a certain elastic movement space. Multiple separation discs 91 are distributed longitudinally in the inner arc surface of the centrifuge chamber 8.
[0025] In the preparation of cyclohexene epoxides, when the material enters the feed pipe 22 through the inlet 21 on the base 2, the material introduction channel of the feed pipe 22 initially constrains and guides the material. When the material descends to the bottom opening of the conical expansion part 4, the conical structure uses the sudden expansion of the cross-sectional area of the dispersion disk to make the material suddenly disperse under the drive of inertia and pressure difference, forming a uniform material flow, which efficiently enters the centrifuge chamber 8. The centrifugal chamber 8 rotates at high speed under the drive of the sliding drum 6, generating a strong centrifugal force field. This is consistent with the principle of the disc separator, which relies on the high-speed rotation of the drum to generate centrifugal force. Under the action of this centrifugal force, materials of different densities exhibit a tendency to separate into layers due to the difference in the magnitude of the centrifugal force. The lighter phase material with lower density moves towards the central area of the centrifugal chamber 8 under the combined action of centrifugal force and material flow. It smoothly enters the light phase chamber 31 of the upper drum 3 through the light phase channel 222 on the outer arc surface of the convex ring 221. The position and angle of the light phase channel 222 match the movement trajectory of the light phase material, ensuring that the light phase material is transferred quickly and without obstruction. The heavier phase material with higher density moves downward along the inner wall of the centrifugal chamber 8 under the drive of centrifugal force and enters the extraction chamber 51 of the lower drum 5. This process is the process of the heavy phase material gathering and being discharged from the drum wall, providing a material basis for the subsequent extraction steps. In the material separation component 9, when the mixed material flows through the separation disc 91, centrifugal force pushes the material through the permeation holes 914 on the outer arc edge guide edge 911. The annular array distribution and pore size of the permeation holes 914 can effectively screen and separate different materials according to the density difference. Intermediate products and impurities with similar densities but slight differences will be separated when passing through the permeation holes 914 due to the different passing speed and trajectory under the action of centrifugal force. At the same time, the spring 93 installed on the separation disc 91 plays a dynamic adjustment function. When the material flow rate and pressure fluctuate, the spring 93 will extend and retract according to the force, driving the separation disc 91 to make appropriate elastic displacement, thereby automatically adjusting the separation gap 7 and the separation effect, ensuring that efficient and stable separation accuracy can be maintained under different working conditions, and having strong adaptability to working conditions.
[0026] like Figure 1 , Figure 4 and Figure 7 As shown, the extraction chamber 51 has a sealing end 511 in the middle of the inner arc surface. The extraction chamber 51 is vertically distributed with the feed pipe 22 and is adapted to the centrifugal chamber 8. A stepped section is provided between the extraction chamber 51 and the lower drum 5. The sliding drum 6 is placed in the inner arc surface of the stepped section.
[0027] The lower drum 5 is placed on the lower surface of the upper drum 3. The extraction chamber 51 at the upper end of the lower drum 5 and the upper drum 3 together form the extraction space. A sealing end 511 is provided in the middle of the inner arc surface of the extraction chamber 51 to ensure the sealing of the extraction chamber 51 and prevent material leakage. The extraction chamber 51 is vertically distributed with the feed pipe 22 and is adapted to the centrifuge chamber 8. A stepped section is provided between the extraction chamber 51 and the lower drum 5. The sliding drum 6 is placed in the inner arc surface of the stepped section so that the sliding drum 6 is fitted into the centrifuge chamber 8, and the upper surface of the sliding drum 6 abuts against the bottom surface of the upper drum 3 and is movably adapted to the gap 7.
[0028] Inside the extraction chamber 51, the sealing end 511 is made of sealing material, forming a tight barrier to isolate external air, impurities and other interfering factors, creating a pure and stable environment for the extraction process. The heavy phase material fully contacts and reacts with the extractant in the extraction chamber 51. With the efficient mass transfer effect brought by centrifugal force, the extraction process can be carried out quickly and fully. This process optimizes the extraction environment, realizes the efficient extraction and separation of cyclohexene epoxides, and produces high-quality target products.
[0029] like Figure 5 and Figure 6As shown, both ends of the arc-shaped segment 102 are provided with bent ends 103. An elastic surface 104 is provided between the arc-shaped segment 102 and one of the bent ends 103. One side of the elastic surface 104 abuts against the inclined edge 61. The upper surface of one of the bent ends 103 is placed at the bottom of the separation disc 91, and the periphery of the conical expansion member 4 is placed in a concave ring. The outer arc surface of the other bent end 103 is placed on the inner arc surface of the upper drum 3 and is in the same plane as the gap 7.
[0030] Finally, the support assembly 10 is installed, and the support guide 101 is movably sleeved into the centrifuge chamber 8. The arc-shaped fold 102 of the support guide 101 near the inner bottom wall of the sliding drum 6 and the bent ends 103 at both ends cooperate with the elastic surface 104. The upper surface of one bent end 103 is placed on the bottom of the separation disc 91 and placed in a concave ring on the periphery of the conical expansion member 4. The outer arc surface of the other bent end 103 is placed on the inner arc surface of the upper drum 3 and is in the same plane as the gap 7, thereby achieving support and stability for the sliding drum 6.
[0031] The stable operation of the sliding drum 6 within the centrifuge chamber 8 is a crucial guarantee for the efficient operation of the equipment. Its stabilizing mechanism involves the close cooperation between the inclined side 61 of the sliding drum 6 and the support assembly 10. The arc-shaped bend 102 on the support guide bar 101, with its curved surface structure, conforms to the movement trend of the sliding drum 6, providing a buffering effect to disperse the impact force during operation. The bent ends 103 at both ends form a flexible support structure with the elastic contact surface 104. When the sliding drum 6 deviates due to uneven material distribution or mechanical vibration during high-speed rotation, the elastic contact surface 104 applies a reverse force to the sliding drum 6 through its own elastic deformation, causing it to quickly return to a stable operating trajectory. This stable support not only ensures the normal operation of the sliding drum 6 but also optimizes the flow environment within the centrifuge chamber 8, reduces material flow resistance, and facilitates smoother material flow and separation within the centrifuge chamber 8, better meeting the operational stability requirements under complex working conditions.
[0032] Figures 1 to 8 The specific work steps are shown below: Material introduction: The mixture containing raw materials for preparing cyclohexene epoxides is conveyed to the feed pipe 22 through the inlet 21 on the base 2. The expansion structure of the bottom opening of the conical expansion part 4 makes the material uniformly dispersed under the action of inertia and pressure difference, and efficiently introduced into the centrifuge chamber 8, providing good conditions for subsequent separation. Centrifugal separation: The centrifugal chamber 8 is rotated inside to generate a strong centrifugal force field. Under the action of centrifugal force, the lighter phase material with lower density moves towards the center of the centrifugal chamber 8 and enters the light phase chamber 31 of the upper drum 3 for storage through the light phase channel 222 on the outer arc surface of the convex ring 221. The heavier phase material with higher density moves down along the inner wall of the centrifugal chamber 8 and enters the extraction chamber 51 of the lower drum 5 to achieve preliminary separation. Fine separation: During the process of material flowing through the separation disc 91, centrifugal force pushes the material through the permeation hole 914 on the guide edge 911. The spring 93 monitors the material pressure in real time. When the material flow and pressure fluctuate, the spring 93 extends and retracts, causing the separation disc 91 to elastically shift and automatically adjust the separation gap 7, accurately separating materials of different densities and further improving the purity of the product. Stable operation guarantee: The inclined side 61 of the sliding drum 6 is closely matched with the support component 10. The arc-shaped fold 102, the bent end 103 and the elastic surface 104 of the support guide bar 101 form a flexible support system. When the equipment is running at high speed, it effectively buffers the impact force caused by uneven material distribution and mechanical vibration, maintains the stable operation of the sliding drum 6, optimizes the material flow path in the centrifuge chamber 8 and reduces resistance. High-efficiency extraction: The sealed end 511 in the extraction chamber 51 adopts a sealing material and structure to isolate external air and impurities. Under the action of centrifugal force, the heavy phase material is fully in contact and mixed with the extractant, which accelerates the mass transfer process and realizes the high-efficiency extraction of cyclohexene epoxides. Finally, the target product is obtained through subsequent processing.
