Description

Technical Field

[0001] The utility model relates to the technical field of dispersion equipment, in particular to a universal dispersion equipment feeding and discharging structure with a CIP self-cleaning function. Background Art

[0002] As a mixing processing equipment widely used in the chemical, pharmaceutical, food, new materials and other industries, the core function of the continuous disperser is to shear, emulsify, homogenize, mix and other operations on different materials. With the continuous improvement of the industrial field's diversified material processing capabilities and production efficiency, traditional continuous dispersers have gradually exposed their limitations in structure and function.

[0003] Currently, the feed and discharge port structures of common continuous dispersers are mostly mechanical interfaces optimized for single or specific material properties (such as good fluidity and moderate viscosity), and have poor adaptability. When the equipment is used to process complex materials with high viscosity, easy sedimentation, easy agglomeration, or different particle characteristics, problems such as poor feeding, blockage, bridging, uneven mixing, and material adhesion to the inner wall of the equipment often occur. These problems not only affect the homogenization and emulsification effect, but also easily lead to consequences such as reduced production capacity, increased energy consumption, and batch instability.

[0004] On the other hand, the problem of equipment cleaning is also particularly prominent; before switching to different products or materials, the disperser needs to be thoroughly cleaned to avoid cross contamination, but traditional cleaning methods rely on manual disassembly, soaking and flushing, or external water spraying, which is inefficient, time-consuming, and there is a large amount of cleaning fluid waste; according to statistics, in order to completely remove residual dead corner materials in pipes and cavities, the amount of cleaning fluid and water resources used in conventional cleaning processes can account for 20% to 30% of the total batch usage, resulting in high operating costs and increased environmental burdens.

[0005] In addition, in the existing technology, equipment cleaning often requires downtime, which interrupts the production rhythm, reduces equipment utilization, and is not conducive to the promotion of continuous and automated production.

[0006] In view of the above, the present application proposes a universal dispersing equipment inlet and outlet structure with CIP self-cleaning function to solve the above problems and improve the homogenization and emulsification processing capabilities of complex materials.

[0034] The main structure of this application includes the coordination between the upper flange 1, the feed port box 2, the discharge port box 3, the box connecting rod 4, the main shaft 5, the rotating assembly 6 and the cleaning assembly 7, and the main structures are all arranged on the equipment frame 8 to work; enabling the disperser to stably and smoothly process a variety of materials with different physical properties, reduce blockage and residue, and reduce the difficulty of material replacement; optimize the material flow path, promote sufficient circulation and mixing, and ensure the efficient uniformity of the product.

[0035] It should be noted that the equipment rack 8 is similar to the existing common disperser. This part is an existing common mature technology and will not be described in detail in this application.

[0036] For reference Figure 2-3, the upper flange 1, the feed port box body 2 and the discharge port box body 3 are connected and fixed to the box body connecting rod 4 by means of hexagon socket head screws 9; this structural equipment is used to construct an integrated fluid module to achieve stable integration and sealed connection of functional units such as feed, discharge and flange connection; a plurality of connection ports are provided on the upper flange 1, and materials can enter the equipment through the connection ports of the upper flange 1 or the quick-install interface of the feed port box body 2;

[0037] Furthermore, both the feed port box 2 and the discharge port box 3 are provided with an enlarged diameter, a smooth inner wall surface and a detachable adapter interface to meet the material processing requirements of different viscosities, particle sizes and material types.

[0038] At the same time, O-rings 13 are provided at the upper flange 1, the feed port box body 2, the discharge port box body 3, the skeleton oil seal 64 and the mechanical seal 62. There are six O-rings 13 in total. The six O-rings 13 are respectively arranged between the upper flange 1, the feed port box body 2, the discharge port box body 3, the skeleton oil seal 64 and the mechanical seal 62 to work to achieve a sealing effect. At the same time, the O-ring material uses PTFE foreskin and fluororubber, which not only meets the conventional leakage prevention requirements, but also meets the advantages of low pollution and easy cleaning.

[0039] For reference Figure 2-3 , the rotating assembly 6 is sleeved on the main shaft 5, and the main shaft 5 is used to drive the rotating assembly 6 to rotate to form an internal material flow channel, and the overall flow channel constitutes an integrated flow channel system that runs through the entire equipment frame 8; and the integrated flow channel system is composed of a guide cavity, a circulation pipeline, a circulation port 11 and its connecting structure arranged inside the equipment frame 8, which runs through the rotating assembly and the cleaning assembly. The main shaft 5 is connected to the drive motor arranged outside the equipment frame 8 through a coupling. The movement of the main shaft 5 drives the rotating assembly 6 to rotate to cause the material to flow into the lowest point of the integrated flow channel system. The circulation port 11 is provided with three Two of the circulation ports 11 form a detachable closed fluid passage through a pipe and the upper flange 1, and the other circulation port 11 forms a detachable closed fluid passage through a pipe and the quick-install interface on the feed port box 2; the three circulation ports 11 are all set at the lowest point of the integrated flow channel system to ensure that the material can be fully collected and sucked to form a closed and controllable circulation system, which drives the rotating component to self-prime, disperse and emulsify through the main shaft drive, ensuring that the material can be realized from the lowest point of the flow channel - circulation - re-enter the cavity to form continuous processing or secondary homogenization emulsification, and the material is pressurized for the second time, and then the pressurized material is ejected from the discharge port box 3.

[0040] Specifically, the rotating assembly 6 includes a rotor 61, a mechanical seal 62, a stator 63, a skeleton oil seal 64, a skewed blade 65 and an impeller 66; the rotor 61, the mechanical seal 62, the stator 63, the skeleton oil seal 64, the skewed blade 65 and the impeller 66 are all set on the main shaft 5; the rotor 61 is arranged at the lower end of the main shaft 5 and is coaxially arranged with the stator 63, with a shear gap provided therebetween; the skewed blade 65 is provided below the stator 63, and the impeller 66 is mounted at the end of the main shaft 5 by means of a gland 661 and axially locked with bolts;

[0041] The main shaft 5 drives the rotor 61 to rotate at high speed, forming strong shear, impact and turbulent homogenization and emulsification effects on the material in the gap, thereby achieving particle crushing, liquid-liquid emulsification or solid-liquid mixing. The inclined blades 65 installed below the stator 63 can guide the material to be transported axially upward when the main shaft rotates, and cooperate with the radial material rejection of the rotor 61 to construct an axial and radial dual flow field, enhance the vortex circulation, and improve the uniformity of homogenization and emulsification. The impeller 66 located at the bottom of the component rotates fixedly with the main shaft 5, has self-priming force and pressure head, sucks in the material at the lowest point of the integrated flow channel system, and then throws it out to complete the bottom material reflux cycle, and also provides strong drive for the subsequent CIP cleaning fluid, which is equivalent to an integrated pump head.

[0042] Furthermore, the rotor 61 adopts a centrifugal design and is equipped with a high-tooth area and a low-tooth area. The high-tooth area generates a radial jet through high-speed rotation, throwing the material forcefully toward the wall of the cavity, and the low-tooth area guides the material to form a circulation along the axial direction. The high-tooth area and the low-tooth area are alternately arranged to form a radial and axial composite flow field.

[0043] The mechanical seal 62 is arranged in the sealing cavity between the main shaft and the shell of the equipment frame 8, and the skeleton oil seal 64 is arranged in the dry area between the main shaft and the shell of the equipment frame 8. Both are common and mature technical means, and this application will not go into details about them.

[0044] For reference Figure 1 The cleaning assembly 7 is arranged on the upper flange 1; the cleaning assembly 7 includes an external interface 71 and a spray port 72. External cleaning liquid is introduced through the external interface 71, enters the integrated flow channel system through a pipeline, enters the integrated circulation system and flows through the area where the rotating assembly 6 is arranged. The impeller 66 and rotor 61 in the rotating assembly 6 are self-primed by negative pressure and act as a circulation pump. After the negative suction cycle, the cleaning liquid entering the integrated flow channel system from the external interface 71 is driven to circulate and be sprayed from the spray port 72 into the integrated flow channel system and the rotating assembly 6 for spraying to perform the cleaning operation. Under the secondary movement, the cleaning liquid uses the mechanical flushing of the fluid and the chemical action of the cleaning liquid to remove residues, forming a closed-loop cleaning circuit and completing the CIP cleaning task. A rotating spray head is provided on the spray port 72, and the cleaning liquid is evenly sprayed inside the equipment through the rotating spray head.

[0045] For reference Figure 1 A jacket cavity is provided in the equipment frame 8, and a jacket inlet 81 and a jacket outlet 82 are provided on the jacket cavity. The jacket cavity is connected to the external circulation system through the jacket inlet 81 and the jacket outlet 82 to achieve heating or cooling of the material inside the dispersion equipment. This part is an existing common and mature technical means, and this application will not go into details about it.

[0046] For reference Figure 1 A temperature sensor interface 12 is provided around the jacket cavity. The temperature sensor interface 12 is used to insert a temperature sensor to realize real-time monitoring of the internal temperature of the equipment, thereby providing accurate feedback for the system temperature control.

[0047] In the present invention, the working steps of the device are as follows:

[0048] 1. Fix the upper flange 1, feed box 2, discharge box 3 and box connecting rod 4 with hexagon socket head screws 9 to complete the assembly of the whole machine module; install O-rings 13 at each connection part of the equipment to ensure sealing, leak-proofness and cleanliness during operation.

[0049] 2. After the equipment is sealed, the material can be introduced into the equipment through the connection port on the upper flange 1 or the quick-install interface on the feed box 2 and enter the homogenization and emulsification area.

[0050] 3. The main shaft 5 is driven to rotate by an external drive motor, prompting the rotating assembly 6 mounted on the main shaft 5 to start working; a shear gap is formed between the rotor 61 and the stator 63 in the rotating assembly 6, and the impeller 66 and the inclined blades 65 drive the material to generate strong shear, mixing, emulsification and self-priming reflux in the cavity.

[0051] 4. The material is sucked into the lowest point of the integrated flow channel system, enters the return line through three sets of circulation ports 11 and returns to the homogenization and emulsification chamber (and the working area of ​​the rotating component 6), forming an axial + radial composite circulation flow field; the high-tooth area realizes strong shear, and the low-tooth area guides axial circulation, thereby enhancing the homogenization and emulsification efficiency.

[0052] 5. After multiple cycles of processing, the material is homogenized and refined, and can finally be discharged through the discharge box; the discharge end of the discharge box 3 is designed with a smooth inner wall and a detachable interface, which is suitable for discharging materials with various viscosities or particle sizes.

[0053] 6. After the discharge is completed, the cleaning liquid is connected to the external interface 71 of the cleaning component 7 and flows into the integrated flow channel system through the connecting pipeline. Driven by the impeller 66 and the rotor 61 of the rotating component 6, negative pressure self-priming is formed, and the cleaning liquid circulates along the integrated channel.

[0054] 7. The cleaning liquid is finally sprayed out through the spray port 72. The spray port is equipped with a rotating spray head, which can evenly spray the cleaning liquid on the rotating component 6 area and the surface of the integrated flow channel system cavity, and complete CIP automatic cleaning with the help of the chemical properties of the cleaning liquid itself and the fluid impact.

[0055] 8. If there is a requirement for the material processing temperature, an external heat exchange medium can be introduced through the jacket inlet 81 and jacket outlet 82 of the jacket cavity to heat or cool the material. At the same time, a temperature sensor can be connected through the temperature sensor interface 12 to monitor and adjust the material processing temperature.

[0056] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
