Description

Technical Field

[0001] This application relates to the field of vacuum emulsification reaction equipment technology, and in particular to a low-residue, easily emptied vacuum emulsification reaction vessel. Background Technology

[0002] Vacuum emulsifying reactors are widely used in chemical, pharmaceutical, food, and daily chemical industries, primarily for mixing, emulsifying, and reacting paste-like, emulsion-like, or high-viscosity materials. When processing high-viscosity materials, the material easily adheres to the inner wall and bottom of the reactor, affecting the thoroughness of discharge and subsequent cleaning efficiency. To solve the problem of material adhesion to the walls, existing vacuum emulsifying reactors typically equip the stirring mechanism with a wall-scraping component.

[0003] However, existing vacuum emulsification reactors still have the following technical shortcomings in practical applications: First, most existing scraper structures are either fixed or normally attached to the wall. During the normal, long mixing phase, the scraper continuously rubs against the inner wall of the vessel, which not only significantly increases the stirring resistance and motor energy consumption, but also easily leads to severe wear between the scraper and the vessel wall.

[0004] Secondly, during the discharge stage, the existing scraper structure often fails to effectively and continuously remove material from different height areas of the inner wall of the vessel without dead angles; moreover, the scraped material lacks a reasonable guiding structure and is prone to secondary retention near the vessel wall or in the transition area at the bottom of the vessel, resulting in an unsatisfactory overall discharge effect.

[0005] Finally, some scraper components with movable designs lack proper sealing and pressure relief mechanisms, making it easy for high-viscosity materials to seep into and accumulate in the mechanical gaps such as the chute. This not only creates hard-to-clean cleaning dead zones but also generates significant hydraulic resistance, causing the scraper to jam or even fail during operation. Summary of the Invention

[0006] In view of the above problems, this application provides a vacuum emulsification reactor with low residue and easy emptying. By setting a sliding inclined plate constrained by a spring and a sealing element in the crossbar groove, a displacement working mode of shrinkage and drag reduction during mixing and outward scraping of the wall during discharge is realized, which effectively solves the problems of high viscosity material residue on the wall and mechanism jamming.

[0007] The low-residue, easily vented vacuum emulsification reactor provided in this application includes a reactor body, a reactor lid at the upper end of the reactor body, a feeding pipe and a gas pipe connected to the reactor lid, an insulation sleeve covering the outside of the reactor body, a discharge port at the bottom of the reactor body, a discharge pipe connected to the discharge port, a discharge valve on the discharge pipe, a mixing mechanism inside the reactor body, and a drive assembly on the reactor lid that is drively connected to the mixing mechanism; the mixing mechanism includes: The rotating rod is coaxially arranged along the central axis of the vessel body and connected to the drive assembly; A stirring roller is disposed on the side wall of the rotating rod; A crossbar is provided on the side wall of the rotating rod along the radial direction, and a groove is provided on the crossbar along its length. An inclined plate is slidably fitted into the groove along the length of the crossbar. The extension direction of the inclined plate is set at an angle to the length direction of the crossbar. The side of the inclined plate away from the rotating rod has an arc-shaped scraping edge that is adapted to the inner wall of the vessel. A telescopic spring is provided in the slide groove, with one end of the telescopic spring connected to the inner wall of the slide groove near the rotating rod and the other end connected to the inclined plate; A sealing element is provided between the inclined plate and the inner wall of the groove.

[0008] Preferably, the drive assembly includes a motor configured to have a first rotational speed and a second rotational speed greater than the first rotational speed; the centrifugal force generated by the inclined plate rotating about the axis of the rotating rod at the first rotational speed is less than the elastic force of the telescopic spring; the centrifugal force generated by the inclined plate rotating about the axis of the rotating rod at the second rotational speed is greater than the maximum elastic restoring force of the telescopic spring, and in this state, the arc-shaped scraper edge abuts against the inner wall of the vessel body.

[0009] Preferably, there are multiple crossbars, which are spaced apart along the axial direction of the rotating rod; the projection portions of any two adjacent inclined plates on the axial direction of the rotating rod overlap.

[0010] Preferably, the thickness of the inclined plate on the side away from the rotating rod is greater than its thickness on the side closer to the rotating rod, and the top surface of the inclined plate forms a guide surface that slopes downward from the inner wall of the vessel towards the rotating rod.

[0011] Preferably, the upper end surface of the inclined plate is provided with an upwardly protruding part, and the protruding part has a rounded corner structure.

[0012] Preferably, the inclined plate is located inside the groove and has a notch on its edge away from the rotating rod. The size of the notch is adapted to the wall thickness of the end of the crossbar away from the rotating rod.

[0013] Preferably, the lower end face of the inclined plate is provided with a plurality of downwardly protruding ribs at intervals along its length.

[0014] Preferably, the sealing element is an elastic sealing lip or sealing strip, which is fixedly connected to the two side walls of the inclined plate and slides against the inner side wall of the groove.

[0015] Preferably, the outer wall surface of the inclined plate is provided with a transition section, and the inclined plate smoothly transitions to the outer wall surface of the crossbar through the transition section; the surface of the inclined plate is covered with an anti-adhesion coating.

[0016] Preferably, the end face of the crossbar away from the rotating rod has a discharge hole that extends into the interior of the chute; the end of the inclined plate located inside the chute has a pressing end face; when the arc-shaped scraper edge abuts against the inner wall of the vessel, the pressing end face extends at least partially into the discharge hole.

[0017] The low-residue, easily emptied vacuum emulsification reactor provided in this application has the following beneficial effects: 1. By setting the mixing and discharging stages to different working states, the inclined plate is kept separated from the inner wall of the vessel during the normal mixing stage, avoiding the scraping component from running against the wall for a long time during emulsification and stirring, thereby reducing mixing resistance and frictional wear between the inclined plate and the inner wall of the vessel; during the discharging stage, the inclined plate is extended to scrape against the wall by changing the direction and speed, so that the scraping action is concentrated in the stage where discharge and wall cleaning are required, which solves the problem of high resistance and obvious wear caused by the normal wall-scraping structure.

[0018] 2. By setting multiple extendable inclined plates along the axial direction of the rotating rod, and having each inclined plate scrape different height areas of the inner wall of the vessel during the discharge stage, the residual material in the upper, middle and lower parts of the inner wall of the vessel can be effectively cleaned. At the same time, the scraping areas of adjacent inclined plates partially overlap, and with the protrusions, notches and arc-shaped scraping edges on the inclined plates, the missed scraping areas between the segmented scraping structures can be reduced, making it less likely for local scraping dead corners to appear on the inner wall of the vessel. This solves the problems of insufficient scraping continuity and excessive residue on the vessel wall in the existing technology during the discharge stage.

[0019] 3. By setting the inclined plate as a guide structure with a thicker outer layer and a thinner inner layer, and cooperating with the bottom structure of the lower end of the vessel body transitioning to the discharge port, the scraped material can move towards the middle and lower discharge port of the vessel body, and is less likely to be retained near the inner wall of the vessel body. At the same time, the ribs, transition parts, anti-adhesion coating and follow-up sealing structure can reduce the risk of material residue and jamming on the surface of the inclined plate, the transition position of the crossbar connection and the sliding groove mating position, respectively, thereby improving the thoroughness of discharge and the convenience of equipment cleaning, and solving the problem that high-viscosity materials are easy to remain on the surface of the scraping parts, the gap of the moving parts and the bottom discharge area.

[0033] like Figures 1 to 7 As shown, this embodiment provides a low-residue, easily vented vacuum emulsification reactor. Its main structure includes a vertically arranged reactor body 1, made of, for example, 316L sanitary stainless steel to meet high cleanliness and corrosion resistance requirements. A reactor cover 3 is detachably and sealed to the upper opening of the reactor body 1 via a flange and a sealing gasket. A feed pipe 4 for adding liquid or solid raw materials and a gas pipe 5 for connecting to an external negative pressure source (such as a vacuum pump) are connected to the top of the reactor cover 3, thereby establishing and maintaining a suitable negative pressure degassing or emulsification environment within the reaction chamber of the reactor body 1. An insulation sleeve 2 is fitted over the outer wall of the reactor body 1, forming an annular heat exchange chamber between the insulation sleeve 2 and the outer wall of the reactor body 1. The insulation sleeve 2 is configured to circulate a heat exchange medium, such as heat transfer oil, steam, or cooling water, to precisely regulate the temperature of the material inside the reactor body 1 through heat conduction. The bottom inner wall of the reactor body 1 has a downward-curving arc-shaped transition structure, and a discharge port is provided at the lowest point to reduce the dead corner of material accumulation at the bottom. The discharge port is connected downward to a discharge pipe 7, and a discharge valve 8, such as a sanitary pneumatic bottom valve with no dead corner, is connected in series on the discharge pipe 7 to control the opening and closing of the reactor discharge.

[0034] The reaction chamber inside the vessel body 1 is equipped with a mixing mechanism for stirring and scraping the vessel walls. A drive assembly 6, which is connected to the mixing mechanism, is fixedly mounted on the upper surface of the vessel lid 3 via a motor support. The mixing mechanism includes a rotating rod 9 vertically arranged coaxially along the central axis of the vessel body 1. The upper end of the rotating rod 9 passes through the vessel lid 3 via a mechanical seal assembly and is connected to the power output end of the drive assembly 6. Multiple stirring rollers 12 are fixedly connected in an axial or circumferential array on the outer cylindrical surface of the rotating rod 9. The stirring rollers 12 rotate synchronously with the rotating rod 9, and are used for basic shearing, dispersion, and mixing of the materials.

[0035] Along the radial direction of the rotating rod 9, an outwardly extending crossbar 10 is welded to the side wall of the rotating rod 9. The crossbar 10 has a groove 16 extending through a portion of its cross-section along its length direction (i.e., the radial extension direction), forming a linear guide structure. A portion of the inclined plate 14 is inserted into and slides within the groove 16 along the length direction of the crossbar 10. In spatial orientation, the extension direction of the inclined plate 14 forms an acute angle with the length direction of the crossbar 10, for example, an inclination angle of 30° to 60°. This inclination configuration allows the inclined plate 14 to generate a downward axial thrust and turbulence effect on high-viscosity materials when it revolves around the axis with the rotating rod 9. The outer edge of the inclined plate 14 away from the rotating rod 9 is machined into an arc-shaped scraper edge that matches the curvature of the cylindrical surface of the inner wall of the vessel body 1, ensuring line or surface contact fit when adhering to the wall.

[0036] A horizontally positioned and resetting telescopic spring 13, such as a corrosion-resistant alloy compression spring, is provided within the inner cavity of the slide groove 16. One end of the telescopic spring 13 is fixedly connected to the inner wall of the slide groove 16 near the rotating rod 9, and the other end is connected to the inner end of the inclined plate 14, thereby applying a normal preload tension to the inclined plate 14 towards the center of the rotating rod 9. Furthermore, a dynamic seal is provided between the outer wall of the inclined plate 14 and the inner wall of the slide groove 16. This seal fills the assembly gap between the two, preventing high-viscosity materials or reaction liquids from seeping into the interior of the slide groove 16 and disrupting the smoothness of the sliding mating surfaces.

[0037] The drive assembly 6 includes a motor and a matching reduction gear. The motor is configured to output a first speed, such as a low-speed mixing gear of 20-50 r / min, and a second speed greater than the first speed, such as a high-speed discharge gear of 100-150 r / min. In the mixing condition, the motor operates at the first speed. The radial centrifugal force generated by the inclined plate 14 rotating around its central axis with the rotating rod 9 is less than the initial preload of the telescopic spring 13. The inclined plate 14 is constrained by the spring and remains in a retracted state. A preset clearance distance is maintained between the arc-shaped scraper edge and the inner wall of the vessel body 1 to reduce the stirring and shearing resistance of the fluid and reduce mechanical wear. In the discharge condition, the motor is switched to the second speed. The centrifugal force generated by the rotation of the inclined plate 14 increases nonlinearly. When the radial centrifugal force is greater than the maximum elastic restoring force threshold of the telescopic spring 13, the inclined plate 14 overcomes the spring tension and extends radially outward along the slide groove 16. Under this extreme working condition, the arc-shaped scraper edge forms a dynamic fit with the inner wall of the vessel body 1 to continuously scrape off the material adhering to the inner wall of the vessel body.

[0038] To improve the cleaning coverage of the entire vessel wall, multiple crossbars 10 are provided, for example, 3 to 5. These crossbars 10 are distributed in an array with equal or variable spacing along the axial direction of the rotating rod 9. The orthographic projections of any two adjacent inclined plates 14 on the axial direction of the rotating rod 9 partially overlap, with an overlap margin set, for example, 10-20 mm. This overlapping topology ensures that, during the discharge and wall scraping process, the spiral scraping trajectories formed by adjacent inclined plates 14 on the inner wall of the vessel can be smoothly connected end-to-end, thereby reducing the annular missed scraping area on the inner wall of the vessel in physical space.

[0039] In terms of the flow guiding structure design, the inclined plate 14 has an uneven thickness in its cross-section along the direction away from the rotating rod 9, that is, the thickness of its outer edge is greater than the thickness of its inner edge near the rotating rod 9. Based on this structural configuration, the top surface of the inclined plate 14 forms a material guiding surface that slopes downward from the inner wall of the vessel body 1 toward the rotating rod 9. When the arc-shaped scraper peels off the material adhering to the vessel wall, the scraped material, under the combined action of its own gravity and the tangential guidance of the inclined surface, quickly slides and converges along the material guiding surface toward the central depression of the vessel body 1 and the bottom outlet, reducing the retention rate of high-viscosity materials near the vessel wall.

[0040] To address the needs for turbulence control and material accumulation prevention in the local flow field, the upper end face of the inclined plate 14 is integrally formed with an upwardly protruding portion 15. This protruding portion 15 has a streamlined, rounded corner transition structure, used to smoothly divert and guide the fluid material flowing over the top of the inclined plate 14, preventing flow stagnation and accumulation at the right-angled edges. Simultaneously, a notch 11 is cut into the edge of the inclined plate 14 located inside the chute 16 and away from the rotating rod 9. When the inclined plate 14 is driven outward by centrifugal force, the opening size of the notch 11 precisely matches the solid wall thickness of the outer end of the crossbar 10, forming a structural clearance space. This allows the arc-shaped scraper edge to extend beyond the end face of the crossbar 10 without mechanical interference and fit against the inner wall of the vessel body 1. Furthermore, the lower end face of the inclined plate 14 is provided with multiple downwardly protruding ribs 17 at equal intervals along its length, used to generate turbulence during rotation to cut the underlying material and disrupt the fluid's adhesion boundary layer at the bottom of the inclined plate 14.

[0041] In terms of interface seepage prevention and isolation design, the sealing element specifically includes an elastic sealing lip or sealing strip, the material of which is, for example, food-grade polytetrafluoroethylene or wear-resistant fluororubber. This sealing element is fixedly connected to the sliding surfaces on both sides of the inclined plate 14 and has a preset interference fit to maintain constant sliding contact with the inner wall of the groove 16, forming a dynamic sealing isolation layer. The outer wall surface of the middle section of the inclined plate 14 is machined with a transition portion 18 (e.g., a rounded chamfer). The inclined plate 14 achieves a smooth geometric transition with the outer contour surface of the crossbar 10 through the transition portion 18, eliminating sharp-angle gaps that easily trap materials. The exposed surface of the inclined plate 14 is covered with an anti-adhesion coating 19, such as a polytetrafluoroethylene coating, which utilizes its extremely low surface free energy to further reduce the surface adhesion rate of paste-like materials.

[0042] In some embodiments, such as Figure 7 As shown, to solve the problem of fluid stagnation in the mechanical movement gap, the end face of the crossbar 10 away from the rotating rod 9 is provided with a discharge hole 20 that penetrates its side wall and connects to the inside of the chute 16; correspondingly, the end of the inclined plate 14 located inside the chute 16 is formed with a pressing end face for force expulsion. During long-term operation in the mixing stage, some material may seep into the cavity of the blind area at the outer end of the chute 16 due to slight deformation of the sealing surface; when switching to the discharge stage, the inclined plate 14 slides outward radially, and its pressing end face applies a positive pushing force to the material retained inside the chute 16. When the arc-shaped scraper edge abuts against the inner wall of the vessel body 1, the pressing end face at least partially extends into and is embedded in the discharge hole 20, forcibly emptying the accumulated material in the chute 16 through the discharge hole 20, eliminating the hydraulic damping effect generated in the chute 16 from a physical structure perspective, preventing the inclined plate 14 from being obstructed and stuck when moving outward, thereby improving the long-term operational stability of the mixing mechanism.

[0043] In another preferred embodiment, the extrusion end face is specifically formed on the bottom surface of the aforementioned notch 11, that is, on the vertical plane of the notch 11 directly opposite the discharge hole 20. This structural arrangement allows the inclined plate 14 to reuse the clearance surface of the notch 11 as the discharge thrust surface, which not only simplifies the processing and forming process, but also makes the thrust axis of the extrusion discharge coincide with the motion axis of the inclined plate sliding guide, thereby improving the mechanical transmission efficiency of the discharge action.

[0044] The low-residue, easily emptied vacuum emulsifying reactor provided in this application embodiment utilizes a rotational speed-controlled displacement mechanism to cause the inclined plate to contract during mixing to reduce resistance and wear, and to extend outwards and adhere to the wall during discharge due to centrifugal force, achieving separation under working conditions. Combined with the design of overlapping inclined plate projections and inclined guide surfaces, the scraped material is continuously guided to the discharge port, reducing dead corners on the inner wall. In addition, the discharge hole at the end of the crossbar cooperates with the extrusion end face of the inclined plate, forcibly squeezing out the accumulated material in the chute when the inclined plate extends outwards, avoiding liquid resistance and jamming of high-viscosity materials, and improving the thoroughness of evacuation and operational stability of the equipment.
