Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically to an anti-vortex feeding device for a fruit pulp emulsification tank. Background Technology

[0002] In the deep processing of fruits, the emulsification and homogenization of fruit pulp is a core process to ensure product taste, stability, and shelf life. The key requirement is to thoroughly mix concentrated fruit flavorings, emulsified oils, and other auxiliary materials with the base pulp to form a uniformly dispersed and stable system, avoiding problems such as layering, clumping, or uneven concentration in certain areas. As a core processing piece of equipment, the feeding method of the emulsification tank directly affects emulsification efficiency, product quality, and production stability. Furthermore, the eddies generated during the feeding process can impact overall production stability and quality.

[0003] Chinese patent CN222196545U discloses a high-efficiency emulsification device for defoamer production, including an emulsification chamber. A servo motor is fixedly connected to the top of the emulsification chamber, and a support ring is fixedly connected to the top of the emulsification chamber. An inlet component is fixedly fitted inside the inner cavity of the support ring. A delivery pump is fixedly connected to the left side of the inlet component. A rotating rod is fixedly fitted to the output shaft of the servo motor. A rotating rod is fixedly connected to the bottom end of the rotating rod, and a liquid outlet is fixedly connected to the bottom end of the rotating rod. A one-way valve is provided in the middle of the liquid outlet. By using a one-way valve to prevent the raw material in the emulsification chamber from flowing back into the inner cavity of the rotating rod, the liquid can be evenly contacted with the raw material in the emulsification chamber. This avoids the situation where the liquid used for emulsification is poured in from the top of the emulsification chamber, which would result in slow mixing and insufficient mixing, thus improving the emulsification efficiency. Chinese patent CN117531401A discloses an emulsification and mixing device for natural carotene in flavored syrups, including a mixing tank with an open top. A tank cover for sealing the open end of the mixing tank is fixedly installed on the mixing tank by screws. A feed hopper connected to the inside of the mixing tank is fixedly installed on the top of the tank cover. A discharge valve connected to the inside of the mixing tank is fixedly installed on the bottom side of the mixing tank. This invention, by setting up a dispersing feeding mechanism, allows the emulsifier to be added into the mixing tank. When adding emulsifier to the mixing tank, the dispersing feeding mechanism feeds the emulsifier through multiple crossbars. The discharge end of the dispersing feeding mechanism is arranged on multiple crossbars, which allows the emulsifier to be dispersed into the mixing tank. When the stirring shaft rotates on the tank cover, the multiple crossbars rotate inside the mixing tank, thus dispersing the emulsifier to various parts of the mixing tank. This replaces the single-point feeding method of emulsifier, which is beneficial for mixing emulsifier and natural carotene, reduces mixing difficulty, and improves mixing efficiency.

[0004] However, both of the aforementioned patents employ traditional feeding methods. When a stream of high-viscosity material impacts the liquid surface inside the tank with significant momentum, a localized low-pressure zone naturally forms inside. This causes the surrounding liquid to rotate downwards and towards the center, inducing a strong feeding vortex. The vortex draws in a large amount of air, leading to product oxidation, deterioration, and excessive foaming. Simultaneously, a channel forms at the center of the vortex, causing subsequent materials to short-circuit directly to the bottom of the tank, easily resulting in uneven axial mixing. To eliminate the vortex, the feeding rate is usually reduced or the overall mixing time is extended, but this method affects production efficiency. Summary of the Invention

[0010] Preferably, the upper surface of the inner wall of the adaptive tube is provided with a plurality of uniformly arranged guide grooves, and the lower end of the inner wall is provided with an installation cavity. A linkage ring is provided in the installation cavity, and a limiting curved surface is provided on the side of the linkage ring away from the inner wall of the installation cavity. Eight spherical parts are uniformly fixedly connected to the limiting curved surface of the linkage ring.

[0011] Preferably, eight torsion spring hinges are evenly arranged at the upper end of the mounting cavity. The fixed end of the torsion spring hinge is fixedly connected to the mounting cavity, and the movable end is fixedly connected to the arc-shaped blade. A limit plate is fixedly connected to the end of the arc-shaped blade away from the torsion spring hinge.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The piston in the buffer tube and the multiple arc-shaped blades in the adaptive tube can effectively avoid the high impulse and unstable fluid caused by water hammer or other energy mutations, thereby affecting the factors that generate eddies from the root and providing basic conditions for subsequent feeding steps. At the same time, the automatic flipping of the arc-shaped blades can automatically change the internal flow area, thereby adapting to the fluid velocity and flow rate. The fluid is combed through the guide tube and centrifuge tube, making the speed and direction of the fluid flow controllable. Finally, the fluid is divided into multiple horizontal jets with the same momentum and the same direction through the dispersing head 7, so that the fluid can flow along the tank wall to form a horizontal hydrodynamic field, thereby breaking the axisymmetric downward flow structure that is generated when the vortex is formed. 3. The device, in conjunction with a low-speed stirring device and a circulating pump, enables the material to be instantly dispersed after entering the emulsification tank, forming a three-dimensional turbulent flow. This eliminates the possibility of excessively high local concentrations or eddies, further improving the anti-eddy effect and enhancing emulsification efficiency and uniformity.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 This invention provides a technical solution: an anti-vortex feeding device for a fruit pulp emulsifying tank 8, comprising a storage tank 1, a guide pipe 5, a centrifuge pipe 6, and a dispersing head 7. The horizontal height of the storage tank 1 can be higher than that of the emulsifying tank 8, thereby increasing the gravitational potential energy of the material flow. A feed pump 11 is fixedly installed inside the storage tank 1. The feed pump 11 can be a screw pump. When it starts, it can pump pectin, sodium carboxymethyl cellulose, concentrated fruit flavor paste, emulsified oil, or secondary diluted fruit pulp from the storage tank 1 into the feeding pipe 2. The pulp inside the storage tank 1 passes through the feeding pipe 2, buffer pipe 3, adaptive pipe 4, guide pipe 5, centrifuge pipe 6, and mixing pipe 9 sequentially through the feed pump 11 into the dispersing head 7, and finally is injected into the emulsifying tank 8 through the dispersing head 7. The output end of the feed pump 11 is connected to... Feeding pipe 2 and adaptive pipe 4 are connected by buffer pipe 3. Buffer pipe 3 has shoulder rings 31 at both ends. Two sets of pistons 33 are respectively sleeved on the outside of feeding pipe 2 and adaptive pipe 4. Buffer springs 32 are connected between pistons 33 and the inner wall of buffer pipe 3. During the opening and closing of components such as feed pump 11, water hammer is likely to occur inside the material because it is in a flowing state. Water hammer is detrimental to the stability of the overall operation. Buffer pipe 3 can effectively reduce damage. When water hammer occurs, it will contact pistons 33 inside buffer pipe 3. At this time, through the sliding of pistons 33, the pressure pulsation of the pipeline can be absorbed by the contraction of buffer springs 32, thereby avoiding pipeline vibration and leakage caused by the impact of raw slurry. At the same time, the shoulder rings 31 can prevent pistons 33 from falling out.

[0021] A liquid level sensor 81 is fixedly connected to the inner wall of the emulsifying tank 8. The liquid level sensor 81 is connected to the processor inside the device to facilitate signal transmission. High-viscosity fruit pulp (such as concentrated pulp from fresh fruits like mango, blueberry, strawberry, and yellow peach) is pre-added to the emulsifying tank 8, along with the liquid base material system from the emulsification and homogenization process. The liquid level sensor 81 can detect the level of the contents of the emulsifying tank 8. The level of the dispersing head 7 inside the emulsifying tank 8 is lower than the level of the liquid level sensor 81, ensuring that the material from the dispersing head 7 comes into full contact with the fruit pulp when it ejects material. A stirring device 82 is installed inside the emulsifying tank 8 to agitate the contents. The high-viscosity fruit pulp in the emulsion tank 8 is stirred to ensure thorough mixing of the fluid material with the high-viscosity fruit pulp. Simultaneously, emulsification can be initiated. A circulation pump 83 is fixedly connected to the bottom of the inner wall of the emulsion tank 8. The circulation pump 83 is controlled by the built-in processor of the device. The output end of the circulation pump 83 is vertically upward. During operation, the circulation pump 83 can drive the material at the bottom of the emulsion tank 8 to flow, thereby allowing the liquid base material to surge from the bottom to the top, thus improving mixing efficiency and speed. At the same time, it can also form a dynamic fluid dynamic field in the emulsion tank 8 before the device officially starts feeding. In addition, the circulation pump 83 also reduces the possibility of clumping and settling of the added fluid material during the feeding process.

[0022] The upper surface of the inner wall of the adaptive tube 4 is provided with several evenly arranged guide grooves 41. The downstream end of the guide grooves 41 is arc-shaped. The guide grooves 41 can guide and sort the material on the outside during the feeding process, avoiding direct impact on the mounting cavity 42. The lower end of the inner wall is provided with a mounting cavity 42. A linkage ring 45 is provided in the mounting cavity 42. A limiting curved surface 46 is provided on the side of the linkage ring 45 away from the inner wall of the mounting cavity 42. When the arc-shaped blade 47 is fully opened, the flow area is the largest. At the same time, the limiting curved surface 46 contacts the fiberboard 49. The linkage ring 45 can limit the rotation angle of the arc-shaped blade 47, avoiding obstruction after the arc-shaped blade 47 is over-opened and reset. Eight spherical parts 410 are evenly fixedly connected to the limiting curved surface 46 of the linkage ring 45. The surface of the spherical parts 410 is coated to improve smoothness. To avoid blockage, eight torsion spring hinges 411 are evenly arranged at the upper end of the mounting cavity 42. The fixed end of the torsion spring hinge 411 is fixedly connected to the mounting cavity 42, and the movable end of the torsion spring hinge 411 is fixedly connected to the upper side of the arc-shaped blade 47. At this time, the torsion spring hinge 411 facilitates the rapid reset of the arc-shaped blade 47. The inner arc surface of the arc-shaped blade 47 is concave inward, and its whole shape is spoon-shaped. The groove part can effectively increase its contact area with the liquid, so that it can open and close sensitively. The end of the arc-shaped blade 47 away from the torsion spring hinge 411 is fixedly connected to a limiting plate 49. The limiting plate 49 is a straight plate with an arc-shaped bend. The eight arc-shaped blades 47 are evenly arranged and their edges are in contact with each other. The whole shape is a cone with a hole in the middle. The outer arc surface of the arc-shaped blade 47 is provided with a guide groove 48. The surface of the guide groove 48 is coated to reduce frictional resistance.

[0023] Several guide rods 43 are fixedly connected inside the mounting cavity 42. The linkage ring 45 is slidably connected to the guide rods 43. The guide rods 43 pass through the linkage ring 45 to provide guidance for its sliding. A return spring 44 is sleeved on the surface of the guide rod 43. One end of the return spring 44 is fixedly connected to the mounting cavity 42, and the other end is fixedly connected to the linkage ring 45. The return spring 44 facilitates the return of the linkage ring 45. In the initial state, the torsion spring is in a stored state, and the return spring 44 is in a stretched state. The eight limiting plates 49 contact each other to form a hole through which liquid can pass. The spherical part 410 contacts the guide groove 48. Through the mutual limiting of the guide groove 48 and the spherical part 410, the linkage ring 45 and the arc-shaped blade 47 can move synchronously. The lower edge of the arc-shaped blade 47 The components overlap, and when the feed rate increases, the liquid flow rate increases. When the high-speed liquid impacts the arc-shaped blades 47, all eight arc-shaped blades 47 can flip downwards simultaneously. At this time, the limiting plate 49 rotates synchronously, thereby increasing the flow area of ​​the liquid in the mounting cavity 42. During the process, when the arc-shaped blades 47 flip, they will squeeze the spherical part 410 through the guide groove 41, thereby driving the linkage ring 45 to slide downwards and stretching the return spring 44. When the feed rate of the liquid decreases and the flow rate decreases, the arc-shaped blades 47 gradually return to their original position, thereby reducing the flow area. Due to the reduction in the flow area, the flow rate of the liquid will increase, so that the overall flow area and flow rate of the material fluid when passing through the mounting cavity 42 can be adaptively adjusted within a certain range by means of the arc-shaped blades 47.

[0024] A flow rectifier assembly 51 is installed inside the guide tube 5, which includes a first flow rectifier blade 511 and a second flow rectifier blade 512. Three first flow rectifier blades 511 and three second flow rectifier blades 512 are provided, and each is fixedly connected to the guide tube 5. One first flow rectifier blade 511 is fixedly connected to one second flow rectifier blade 512. The first flow rectifier blade 511 is S-shaped, and the second flow rectifier blade 512 is located downstream of the first flow rectifier blade 511. When material flows into the guide tube 5 from the adaptive tube 4, it first impacts the S-shaped curved surface of the first flow rectifier blade 511. Due to the design of the curved surface, the fluid is... The forced twisting forces the chaotic radial and circumferential velocity components of the fluid to be reorganized, thereby forming a swirling flow with a unified direction, i.e., along the curve direction of the first rectifier blade 511, and with controllable intensity. This swirling flow then enters the vertical straight channel formed by the second rectifier blade 512. At this time, the second rectifier blade 512 aligns the rotation axis of the fluid with the axis of the pipe, and converts the excessive tangential kinetic energy into axial kinetic energy. Finally, the output is a stable axial mainstream with a small amount of pre-swirl, thus creating excellent conditions for the rotation of the guide rotor 61 in the downstream centrifuge tube 6.

[0025] Several guide rotors 61 are installed inside the centrifuge tube 6. The guide rotors 61 are S-shaped and their twist is greater than that of the rectifier blade 511. The guide rotors 61 are frustoconical in shape. A bearing 62 is installed inside the centrifuge tube 6. A frame 63 is fixedly connected to one side of each guide rotor 61. The frame 63 is rotatably connected to the centrifuge tube 6 via an interference fit with the bearing 62. The bearing 62 remains sealed. Because the rectifier blade 511 and the guide rotors 61 rotate in the same direction, when the first portion of axially swirling fluid enters the centrifuge tube 6, it will first impact the negative pressure surface of the guide rotors 61. At this time, due to the... The flow rotor 61 is S-shaped and has a large degree of torsion. The fluid exerts a significant tangential force on the blades, thereby generating a driving force that drives the flow rotor 61 and the frame 63 to start rotating. As the speed of the flow rotor 61 increases, its centrifugal effect is enhanced. After the fluid enters the flow channel of the flow rotor 61, it will be driven and forcibly accelerated by the high-speed rotating flow rotor 61. The curved shape of the flow rotor 61 can continuously transfer the mechanical energy of rotation to the fluid, thereby giving the fluid a huge centrifugal speed and tangential force. Finally, the fluid is thrown downward from the outer edge of the impeller at extremely high speed and pressure.

[0026] The mixing tube 9 is longer than the centrifuge tube 6 and the dispersing head 7. The mixing tube 9 provides space for the fluid flowing out of the centrifuge tube 6, allowing the kinetic energy of the high-speed fluid to be converted into pressure energy, thus making its flow velocity distribution more uniform as it enters the dispersing head 7. Several guide plates 71 are fixedly connected to the inner wall of the dispersing head 7. The number of guide plates 71 is coprime to the number of guide rotors 61 to avoid resonance. The bending direction of the guide plates 71 is the same as the rotation direction of the guide rotors 61, thus preserving tangential force. Simultaneously, the curved surface of the guide plates 71 converts the radial and tangential velocities of the fluid into a resultant force along the direction of the guide plates 71. To reduce energy loss, a jet nozzle 72 is provided between every two guide plates 71. A guide lip 73 of equal size to the guide plate 71 is fixedly connected to the outer wall of the dispersing head 7. The guide lip 73 is tangent to the dispersing head 7. The jet nozzle 72 is rectangular and penetrates the side wall of the dispersing head 7. The jet nozzle 72 is connected to the guide lip 73, so that the fluid is injected into the emulsification tank 8 through the guide lip 73 after the velocity components in the vertical direction and other disordered directions are eliminated. During this process, the guide lip 73 can also reshape the fluid. The dispersing head 7 and the guide lip 73 are both kept horizontal and the overall rotation direction of the guide lip 73 is the same as that of the guide plate 71, thus forming a rotating flow field.

[0027] Before starting the feeding operation, the operator must first inject a sufficient amount of high-viscosity fruit pulp, emulsified oil, or other liquid base material system into the emulsification tank 8 until the liquid level reaches the preset liquid level sensor 81. This ensures that the subsequently added material will be injected into the interior rather than impacting the liquid surface and causing splashing and air entrapment. At this time, the entire structure of the dispersing head 7 installed in the tank is completely submerged below the liquid surface, thus creating a prerequisite for submerged and stable feeding. Subsequently, the system pre-starts the stirring device 82 and the bottom circulation pump 83 in the emulsification tank at low power. The stirring device 82 runs at a low speed to initially break the static state of the liquid. At the same time, the circulation pump 83 draws liquid from the bottom of the tank and makes it surge upward. The two work together to pre-build a flowing liquid field in the emulsification tank 8, thereby improving the subsequent mixing efficiency.

[0028] Then, the concentrated fruit flavor paste or secondary diluted fruit pulp to be added is put into the storage tank 1, and then the feed pump 11 (a screw pump or rotary pump suitable for conveying high viscosity materials can be selected) is started. The feed pump 11 smoothly pumps the material in the storage tank 1 out and conveys it to the feed pipe 2 through the feed pipe 2. After passing through the feed pipe 2, the material fluid enters the buffer pipe 3. The buffer pipe 3 is equipped with a piston 33 and a buffer spring 32, which absorbs and attenuates the instantaneous pressure peaks generated by the start and stop of the pump or the flow regulation, thereby converting the unstable pressure pulsation into the elastic potential energy of the spring, thus protecting the subsequent components from impact and ensuring that the fluid pressure entering the adaptive pipe 4 is relatively stable.

[0029] When fluid enters the adaptive pipe 4, the fluid pressure acts on the spoon-shaped and evenly distributed arc-shaped blades 47 inside the pipe. When the flow rate and velocity increase, the impact force of the fluid overcomes the torque of the torsion spring hinge 411 and the tension of the return spring 44, pushing all the arc-shaped blades 47 to flip downwards synchronously. At this time, the linkage ring 45 slides along the guide rod 43, causing the central through hole formed by the arc-shaped blades 47 to gradually expand, thereby adaptively increasing the flow area. Conversely, when the flow rate decreases, under the action of the torsion spring hinge 411 and the return spring 44, the arc-shaped blades 47 gradually return to their original position. At this time, the fiberboard 4... The reduced size of the through-hole in section 9 enables adaptive control of the pipe's flow cross-section, thus preventing the generation of initial eddies due to drastic flow velocity fluctuations caused by changes in flow rate. After the fluid has undergone stabilization and adaptive adjustment, it will enter the guide pipe 5. At this point, the rectifier assembly 51, which is fixedly installed inside the guide pipe 5, can finely comb the fluid. The S-shaped curved surface of the rectifier blades 511 will cause the turbulent fluid to flow along a preset trajectory, thereby reorganizing its chaotic radial and circumferential velocity components and outputting a bundle of axial pre-swirling flow with a rotation axis coinciding with the pipe axis, a unified direction of rotation, and controllable intensity.

[0030] Subsequently, the pre-swirling axial flow enters the centrifuge tube 6 at high speed. Impacting the internal frustum-shaped, highly tortuous S-shaped guide rotor 61, it drives the rotor to rotate. During this process, the tangential force of the fluid on the guide rotor 61 generates a driving torque, causing the blade assembly and frame 63 to rotate at high speed via the bearing 62. The rotating guide rotor 61 continuously performs work on the subsequent fluid, converting the fluid's pressure and kinetic energy into radial centrifugal velocity and circumferential tangential velocity through centrifugal effect. This disturbance achieves the first amplification and transformation of energy. The high-energy rotating jet ejected from the centrifuge tube 6 then enters the mixing tube 9. The mixing tube 9 provides a kinetic energy buffer and pressure equalization space for the high-speed, turbulent fluid. At this point, the excessively large vortex structure in the fluid is weakened, the velocity distribution across the cross-section becomes more uniform, and the flow becomes smoother.

[0031] Finally, the stabilizing rotating fluid enters the dispersing head 7. The guide plates 71, which are uniformly distributed circumferentially inside the dispersing head 7, have the same curvature direction as the rotation direction of the guide rotor 61, thereby maximizing the retention of the fluid's rotational momentum and guiding it into flow along the direction of the guide plates 71. Subsequently, the fluid passes through the rectangular injection port 72 and is finally shaped by the tangential guide lip 73 that penetrates it. The fluid forced out by the guide lip 73 is ejected horizontally in a direction tangential to the outer wall of the dispersing head 7. Through multiple jets closely adhering to the inner wall of the emulsifying tank 8, the material can be injected into the pre-flowed fruit pulp for mixing and open emulsification operation.

[0032] Working principle: The buffer tube 3 and adaptive tube 4 can avoid the high-impact and unstable fluid caused by water hammer and sudden energy changes. The guide tube 5 and centrifuge tube 6 can sort the fluid, making the speed and direction of the fluid flow controllable. Finally, the dispersing head 7 can form multiple horizontal jets with the same momentum and uniform direction, so that the fluid can flow along the tank wall to form a horizontal hydrodynamic field. Since the jet is horizontal and tangential, it can break the axisymmetric downward flow structure pre-generated when the vortex is formed. At the same time, the stirring device 82 with low speed and the circulating pump 83 can disperse the material instantly, thereby eliminating the possibility of excessive local concentration or vortex.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
