It includes a main frame base, a linkage filtration mechanism and a drive motor unit. The linkage filtration mechanism includes a cylindrical cavity, a hemispherical cavity, and a multi-stage grinding rotor group. At the bottom of the multi-stage grinding rotor group, there is also an initial separation leakage cavity module integrally placed in the hemispherical cavity. Through the dynamic matching design of the multi-stage grinding stator and the sorting and reflux filtration mechanism, a full-process closed-loop system from grinding to screening and then to re-grinding is constructed. Aiming at the problem that the existing colloid mills rely on external screening equipment, resulting in a fragmented process, the linkage structure of the three-stage grinding stator group and the corresponding sorting layer is used to enable unqualified particles to automatically flow back to the matching grinding stage according to the particle size.

After the unqualified particles are transferred to the two-side cylindrical cavities by the adsorption pump, the real-time synchronous adjustment of the screening accuracy and the grinding parameters is realized.

Description

Technical Field

[0001] The present invention relates to the technical field of colloid mills, and more specifically, to an interlocking filtration device applicable to a colloid mill. Background Art

[0002] As an efficient wet material micro-processing equipment, colloid mills are widely used in the fields of food, medicine, and chemical industry. Their working principle is based on the shearing force, frictional force, and high-frequency vibration between a high-speed rotating rotor and a stator, and different particle size processing requirements are achieved by adjusting the tooth gap of the grinding teeth. For example, in the prior art when processing corn kernels, the colloid mill gradually refines the raw materials to the target particle size through multi-stage grinding, and its core performance depends on the matching between the rotational speed of the rotor and the grinding tooth structure.

[0003] However, in processing scenarios that require multi-stage grinding such as corn kernels, the existing colloid mills have significant defects. Due to the uneven initial particle sizes of the materials, some particles may not reach the target particle size after single grinding, and manual or external screening equipment is required for filtration, and the unqualified particles are re-fed into the colloid mill for secondary processing. Moreover, it is difficult to dynamically match the precision of the external screen of the external filter with the real-time grinding parameters of the colloid mill, resulting in low efficiency of repeated grinding and increased energy consumption. Therefore, although it can perform preliminary grading, it still relies on manual adjustment of the screen mesh number and cannot adaptively adjust the recovery strategy according to the grinding precision.

[0004] Further analysis reveals that the core of the above problems lies in the separation of the grinding and filtration systems in the prior art. Taking the processing of corn slurry as an example, the rotor gap of the colloid mill determines the instantaneous grinding precision, while the external screening equipment can only statically match a fixed mesh screen. When the grinding parameters are dynamically adjusted, such as switching the rotational speed to cope with the change in material viscosity, the screening standard cannot be synchronized and adapted, resulting in some particles being misjudged as qualified due to the too-fine screen or being too coarse and requiring repeated backflow, that is, the situation of missed screening or redundant over-screening occurs.

The movable sleeve group includes a second sleeve fixedly installed at the exact bottom of the straight pipe, and also includes a first sleeve fixedly installed at the center of the bottom of the cylindrical cavity. The bottom of the first sleeve is communicated with the conduit connected to the output end of the adsorption and pumping unit. A concave sleeve is fixedly installed at the bottom of the second sleeve, and the second sleeve is movably installed on the top of the first sleeve through the concave sleeve.

[0015] As a further solution of the present invention: The sorting and reflux filtering mechanism further includes several layers of conical leaky trays fixedly installed on the inner wall of the cylindrical cavity. And corresponding multi-stage grinding stator group grinding stage leaky openings are sequentially opened in several layers of conical leaky trays from top to bottom. A hollow sleeve is fixedly installed at the center position of several layers of conical leaky trays. The whole hollow sleeve is movably sleeved on the outer surface of the straight pipe, and a magnetic adsorption coating is fixedly installed on the outer surface of the straight pipe corresponding to the position of each layer of conical leaky tray.

[0016] As a further solution of the present invention: the conical hat-shaped leakage disc divides the interior of the cylindrical cavity into several independent chambers, and a magnetic ring sleeve is movably installed on the upper surface of the conical hat-shaped leakage disc located in each chamber, and the magnetic end on the inner annular surface of the magnetic ring sleeve corresponds one-to-one to the magnetic coating on the straight tube, and a stirring plate attached to the conical hat-shaped leakage disc is fixedly installed on the outer annular surface of each magnetic ring sleeve, and a scraper is movably installed through a first sleeve in the bottommost chamber separated by several layers of conical hat-shaped leakage discs, and the top of the scraper is adsorbed and corresponds to the adjacent magnetic ring sleeve across the conical hat-shaped leakage disc, the scraping end of the scraper is attached to the bottom surface of the cylindrical cavity, and the bottom surface of the cylindrical cavity is provided with a first connecting leak leading to the interior of the hemispherical cavity.

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) This solution constructs a closed-loop system for the entire process from grinding to screening and then grinding through the dynamic matching design of the multi-stage grinding stator and the sorting reflux filtration mechanism. In order to solve the problem that the existing colloid mill relies on external screening equipment, which leads to process fragmentation, the linkage structure of the three-stage grinding stator group and the corresponding sorting layer is used to enable the particles that do not meet the standards to automatically flow back to the matching grinding level according to the particle size. Specifically, the initial screening is completed by the hemispherical cavity at the bottom of the grinding chamber. After the particles that do not meet the standards are transferred to the cylindrical cavities on both sides by the adsorption pump, they are screened by the layered bamboo hat-shaped leakage disc according to the three levels of rough shearing, fine grinding and homogenization, and are accurately returned to the corresponding grinding gap through the tangentially connected leakage port, realizing the real-time synchronous adjustment of screening accuracy and grinding parameters, avoiding the repeated processing caused by the disconnection between the traditional external screen and the dynamic grinding parameters.

[0021] (2) The frustum-shaped leak orifice cavity shell driven by the gear sleeve disc and the hemispherical cavity shell cooperate with each other. Combining the rotational scraping of the arc-shaped stirring arm and the cavity-conducted vibration of the ultrasonic vibration head, the self-cleaning of the leak holes and the enhancement of particle fluidity are synchronously achieved during the sorting process. In particular, the magnetic suspension cleaning group, through the cooperation of the magnetic suction head and the electric control magnetic suction unit, while keeping the static cleaning plate continuously scraping the residues in the leak holes, transmits the ultrasonic vibration to the entire sorting system, overcoming the technical problem that the traditional flat sieve plate is prone to caking in high-viscosity materials.

[0022] (3) Through the magnetically driven dynamic stirring and closed-loop reflux mechanism, the sorting accuracy and system stability are significantly improved. The sorting reflux mechanism adopts the cooperation of a straight pipe magnetic suction coating driven by a servo motor and a magnetic suction ring sleeve to drive the multi-stage conical leak trays to rotate and stir synchronously, enabling the particles to be sorted by layer under the combined action of centrifugal force and magnetic suction scraper. The unqualified particles return to the preliminary separation module through the first connecting leak orifice to form a closed loop, while the scraper assembly clears the residual particles at the bottom through magnetic suction linkage.

[0042] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for schematic purposes and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0043] The following will describe in detail a linkage filtering device applicable to a colloid mill provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For those skilled in some well-known technical fields, other alternative methods can also be used for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0044] As Figures 1 to 7 shown, an embodiment of the present invention provides a linkage filtering device applicable to a colloid mill, including a main frame base 1. On both sides of the upper surface of the main frame base 1, a linkage filtering mechanism 2 and a drive motor unit 5 are fixedly installed. The linkage filtering mechanism 2 includes a cylindrical cavity 21. At the bottom of the cylindrical cavity 21, a hemispherical cavity 22 which is entirely located inside the main frame base 1 is fixedly installed. Inside the hemispherical cavity 22, a multi-stage grinding rotor group 11 extending into the cylindrical cavity 21 is arranged. At the bottom of the multi-stage grinding rotor group 11, an initial separation leakage cavity module 12 which is entirely located in the hemispherical cavity 22 is also arranged.

[0045] A grinding chamber 23 is formed inside the cylindrical cavity 21. On the inner wall of the grinding chamber 23, a multi-stage grinding stator group 24 corresponding to the multi-stage grinding rotor group 11 is fixedly installed. On the side end of the cylindrical cavity 21, two cylindrical cavities 25 which are located outside the grinding chamber 23 and are separated by 180 degrees are formed. Inside each cylindrical cavity 25, a sorting and reflux filtering mechanism 7 is arranged.

[0046] Among them, the sorting and reflux filtering mechanism 7 is provided with different sorting layers corresponding to the grinding particle sizes of the multi-stage grinding stator group 24 from top to bottom. At the position where each sorting layer is tangent to the grinding chamber 23 on the side wall of the cylindrical cavity 25, a second communication leakage port 28 is formed to re-reflux the sorted particles onto the multi-stage grinding stator group 24 of the corresponding grinding stage for secondary grinding.

[0047] In order to solve the problem that the colloid mill system in the prior art cannot perform reflux reprocessing with particle-level matching of the processed particulate material, the above technical solution is adopted for solution. The above technical solution mainly consists of a main frame base 1, a linkage filtering mechanism 2, and a sorting reflux filtering mechanism 7. The main frame base 1 serves as the main support system of the device and plays a role in fixing each component. In the prior art, it is generally composed of a high-rigidity cast iron with an internal flow channel structure, and the internal flow channel is several channels for transporting particulate material. The configured linkage filtering mechanism 2 includes a cylindrical cavity 21 and a hemispherical cavity 22. The cylindrical cavity 21 is used for colloid mill processing, which includes a multi-stage grinding rotor group 11 and a multi-stage grinding stator group 24. Through the shearing rotation of the multi-stage grinding rotor group 11 and the multi-stage grinding stator group 24, the poured particulate material is processed. The definition of multi-stage is because in the actual processing process, especially for particulate materials at the particle level, it will be divided into three levels: rough shearing, fine grinding, and homogenization. Therefore, for the multi-stage grinding rotor group 11 and the multi-stage grinding stator group 24, the specific manifestation is the different tooth shape and gap design. The hierarchical division of the stator and rotor will be described in detail at the corresponding component positions below. The hemispherical cavity 22 is equivalent to opening a cavity at the bottom of the processing end, so that the particulate material after three-stage grinding is in this cavity, and the initial sorting operation is carried out through the initial sorting leakage cavity module 12. The material that meets the particle level is discharged, and the material that does not meet is transported to the cylindrical cavities 25 on both sides. Through the sorting reflux filtering mechanism 7 configured in the cylindrical cavities 25, according to the criteria of rough shearing, fine grinding, and homogenization at the three levels, different particles are transported to the gaps of different rotor levels for the operation of reflux reprocessing with particle-level matching. The division of the corresponding sorting reflux filtering mechanism 7 will be specifically described and analyzed in the following specific components.

[0048] As Figures 1 to 7 shown, the multi-stage grinding rotor group 11 includes a support bracket 111 fixedly installed on the inner top side wall of the hemispherical cavity 22. The surface of the support bracket 111 is movably installed with a gear sleeve disc 112 concentric with the grinding chamber 23. Two third communication leakage ports 29 are opened on one side of the side wall of the hemispherical cavity 22 facing the drive motor unit 5. The output end of the drive motor unit 5 is meshed and installed with a linkage track sleeve 6. The linkage track sleeve 6 is hermetically penetrated into the interior of the hemispherical cavity 22 through the third communication leakage port 29 and is meshed with the gear sleeve disc 112. The upper surface of the gear sleeve disc 112 is fixedly installed with a multi-stage rotor disc 113 integrally placed inside the grinding chamber 23 and corresponding to each grinding stage of the multi-stage grinding stator group 24.

[0049] Among them, the configured multi-stage grinding rotor group 11 mainly includes multi-stage rotor disks 113, and the multi-stage rotor disks 113 are movably installed inside the grinding chamber 23 through gear sleeve disks 112. The configured support bracket 111 is a support sleeve structure. During the working process, the rotation of the output end of the drive motor unit 5 drives the linkage track sleeve 6 to rotate synchronously. The linkage track sleeve 6 meshes with the gear sleeve disk 112. Therefore, during the operation of the drive motor unit 5, the gear sleeve disk 112 is controlled to rotate, so that the multi-stage rotor disks 113 on the upper surface of the gear sleeve disk 112 are attached to the multi-stage grinding stator group 24 for multi-stage grinding processing. The division of the grinding stages is specifically as follows:

[0050] Coarse shearing stage: The outer surface of the rotor is in the shape of a mace tooth, and the overall tooth shape is arranged at a 45-degree oblique angle; the outer surface of the stator is in the shape of a serrated groove.

[0051] Fine grinding stage: The outer surface of the rotor is in a helical tooth structure, and the overall helical tooth has a 30-degree helix angle; the outer surface of the stator is in the shape of a honeycomb microporous groove.

[0052] Homogenization stage: The outer surface of the rotor is in a smooth tooth pattern, and the overall tooth pattern has a 10-degree smooth transition; the outer surface of the stator is mirror-polished.

[0053] Specifically, the division of the set grinding stages can be adjusted adaptively according to the actual grinding object. For example, during the actual processing, the texture of the processing object can be felt, and the tooth depth of the mace tooth shape in the coarse shearing stage, the tooth depth of the helical teeth in the fine grinding stage, and the tooth pitch of the smooth tooth pattern in the homogenization stage can be changed. The purpose is that in the coarse shearing stage, the particle size of the crushed corn kernels can be reduced to 100 to 200 microns, that is, the stage of releasing starch and fiber. In the fine grinding stage, the particle size of the crushed corn kernels is reduced to 50 to 100 microns, that is, the stage of breaking the protein and starch complex. In the homogenization stage, the particle size of the crushed corn kernels is less than 50 microns, that is, the stage of eliminating the shear marks on the particle surface, and the standard for entering the finished product tank is also achieved through the homogenization stage. The drive motor unit 5 configured is a permanent magnet direct drive motor in the prior art, which can achieve precise matching of speed and torque during the processing.

[0054] Such as Figures 1 to 7As shown, the initial separation leakage cavity module 12 includes a frustum-shaped leakage orifice cavity shell 122 fixedly installed on the bottom surface of the gear sleeve disc 112. The bottom surface of the frustum-shaped leakage orifice cavity shell 122 is fixedly connected to a hemispherical cavity shell 121. The hemispherical cavity shell 121 has the same center of the circle as the hemispherical cavity 22. The upper surface of the frustum-shaped leakage orifice cavity shell 122 is circumferentially provided with a plurality of leakage orifices for standard granular materials to pass through. At the middle position of the bottom of the hemispherical cavity shell 121, there is a discharge pipe opening 124 for discharging standard granular materials. A discharge pipe 125 is fixedly installed outside the discharge pipe opening 124. The discharge pipe 125 passes through the hemispherical cavity 22 as a whole. At the position of the bottom of the hemispherical cavity 22, there is a first reserved circular opening 211 for the discharge pipe 125 to pass through. An outlet leakage orifice 4 passing through the main frame base 1 is fixedly installed at the passing end.

[0055] Among them, the configured hemispherical cavity shell 121 and the frustum-shaped leakage orifice cavity shell 122 are of an integral structure. The granular materials falling from the grinding chamber 23 fall on the surface of the frustum-shaped leakage orifice cavity shell 122. The frustum-shaped leakage orifice cavity shell 122 is fixedly connected to the gear sleeve disc 112. During the rotation of the gear sleeve disc 112, the frustum-shaped leakage orifice cavity shell 122 can also rotate accordingly, accelerating the materials falling on the surface of the frustum-shaped leakage orifice cavity shell 122 to pass through the leakage orifices. The leakage orifices on the surface of the frustum-shaped leakage orifice cavity shell 122 are set to be less than 50 microns, that is, the particle size that can be discharged. Specifically, the granular materials falling from the grinding chamber 23, those less than 50 microns enter the interior of the hemispherical cavity shell 121, are discharged to the outlet leakage orifice 4 through the discharge pipe 125 at the inner bottom of the hemispherical cavity shell 121, and are discharged from the outlet leakage orifice 4. The particles that do not pass through the frustum-shaped leakage orifice cavity shell 122 will fall along the frustum-shaped leakage orifice cavity shell 122 to the outside of the hemispherical cavity shell 121 for initial separation.

[0056] As Figures 1 to 7 shown, there is a gap between the hemispherical cavity 22 and the hemispherical cavity shell 121 for non-standard granular materials that do not pass through the frustum-shaped leakage orifice cavity shell 122 to leak into this gap along the outer surface of the frustum-shaped leakage orifice cavity shell 122. At the bottom position of the outer side wall of the hemispherical cavity 22, there is an outer arc cavity 210. A leakage trough opening 212 is provided at a position of the outer arc cavity 210 close to the discharge pipe 125. Reserved conduit openings 213 communicating with the upper cylindrical cavity 25 are provided at both ends of the outer arc cavity 210. A second reserved circular opening 214 is provided on the outer side wall of each reserved conduit opening 213. An adsorption and pumping unit 9 is fixedly installed through the second reserved circular opening 214. A conveying conduit 10 extending to the bottom of the outer arc cavity 210 and close to the outer side wall of the discharge pipe 125 is fixedly installed at the adsorption end of the adsorption and pumping unit 9.

[0057] Among them, there is a gap between the configured hemispherical cavity 22 and the hemispherical cavity shell 121, that is, there is an arc-shaped cavity. As described above, the particles that do not pass through the frustum-shaped leaky cavity shell 122 will fall along the frustum-shaped leaky cavity shell 122 to the outside of the hemispherical cavity shell 121, that is, fall into the gap between the hemispherical cavity 22 and the hemispherical cavity shell 121, and enter the outer arc cavity 210 through the material leakage slot 212. Since both the hemispherical cavity shell 121 and the hemispherical cavity 22 are hemispherical, it is easier for the particles to be added to the bottom of the sphere, that is, the outer arc cavity 210, during the process of passing through. The configured outer arc cavity 210 is an arc-shaped cavity structure as a whole. Adsorption and pumping unit 9 for transferring particles that do not meet the processing standards are arranged on both sides of the cavity. Through the conveying conduit 10 fixedly installed at the adsorption end of the adsorption and pumping unit 9 and extending to the position near the outer side wall of the discharge pipe 125 at the bottom of the outer arc cavity 210, the particles entering the outer arc cavity 210 are adsorbed and transferred to the cylindrical cavities 25 on both sides for real-time sorting, reflux and filtration treatment. The configured adsorption and pumping unit 9 is a pumping structure in the prior art that can stably transport powdery and pasty substances, such as pneumatic diaphragm pumps, vacuum adsorption machines and other equipment. And in order to ensure the sealing performance of the first reserved round opening 211 during the operation of the device, a sealing ring is provided at the position where the discharge pipe 125 contacts the first reserved round opening 211.

[0058] As Figures 1 to 7 shown, an arc-shaped stirring arm 126 extending into the gap between the hemispherical cavity 22 and the hemispherical cavity shell 121 is also fixedly installed on the outer side wall of the discharge pipe 125. The inner arc side of the arc-shaped stirring arm 126 fits against the outer wall of the hemispherical cavity shell 121, and the outer arc side of the arc-shaped stirring arm 126 fits against the inner wall of the hemispherical cavity 22. The conduit connected to the output end of the adsorption and pumping unit 9 is connected to the center position at the bottom of the cylindrical cavity 25 through the reserved conduit opening 213. A servo motor 26 is fixedly installed on the top of each cylindrical cavity 25, and the top of the cylindrical cavity 25 is sealed by the installed servo motor 26. A feed hopper 3 is fixedly installed on the upper surface of the cylindrical cavity 21.

[0059] Among them, the configured arc-shaped stirring arm 126 and the discharge pipe 125 are of an integral structure and are in the shape of a comb ruler as a whole. During the actual working process, in order to improve the fluidity of the particles falling from the grinding chamber 23 into the hemispherical cavity 22 and increase the smoothness of their entry into the outer arc cavity 210, during the rotation of the hemispherical cavity shell 121, by using the rotational force of the hemispherical cavity shell 121, the arc-shaped stirring arm 126 is controlled to stir in the gap between the hemispherical cavity shell 121 and the hemispherical cavity 22, improving the stability of the entire system. Emphasizing that the inner arc side of the arc-shaped stirring arm 126 fits against the outer wall of the hemispherical cavity shell 121 and the outer arc side of the arc-shaped stirring arm 126 fits against the inner wall of the hemispherical cavity 22 is to enable the arc-shaped stirring arm 126 to transmit the vibration force through the fitting relationship during subsequent vibration, so that the granular material can be accompanied by vibration during the process of processing and conveying, in order to avoid the agglomeration of fine particles.

[0060] In summary, the specific working principle of the configured primary separation leakage cavity module 12 is as follows:

[0061] First of all, the material to be processed is poured into the cylindrical cavity 21 through the feeding funnel 3. By turning on the driving motor unit 5, during the process of the linkage track sleeve 6 at the output end of the driving motor unit 5 pulling the gear sleeve disk 112 to rotate, the multi-stage rotor disk 113 can be controlled to rotate at a high speed inside the grinding chamber 23. Cooperating with the multi-stage grinding stator group 24 on the inner wall of the grinding chamber 23, according to the multi-stage grinding effect from top to bottom, the poured material is subjected to multi-stage grinding treatment.

[0062] Then, the ground particles fall from the grinding chamber 23 and enter the hemispherical cavity 22. The material of the standard particle size that meets the requirements enters the inside of the hemispherical cavity shell 121 through the leak hole of the frustum-shaped leak hole cavity shell 122 and is discharged through the discharge pipe 125 at the bottom of the hemispherical cavity shell 121. The material that cannot pass through the leak hole of the frustum-shaped leak hole cavity shell 122 leaks into the gap between the hemispherical cavity shell 121 and the hemispherical cavity 22 and is stirred at high speed in real time by the arc-shaped stirring arm 126, and finally converges into the outer arc cavity 210 through the leakage trough opening 212.

[0063] Finally, the particles that enter the outer arc cavity 210 are adsorbed by the adsorption and pumping unit 9 at the second reserved round opening 214 and are transferred outward through the conveying conduit 10 at the adsorption end of the adsorption and pumping unit 9 into the inside of the cylindrical cavity 25, that is, into the processing area of the sorting, reflux and filtration mechanism 7. The whole process is synchronized with the grinding stage. On the one hand, there is no need for manual secondary transfer of materials, and on the other hand, there is no need to add additional driving force, increasing the stability of material conveying while ensuring the integrity of the conveying end.

[0064] AsFigures 1 to 7 As shown, the sorting reflux filtering mechanism 7 includes an outrigger 73 fixedly mounted on the output end of each servo motor 26, a curved conduit 74 fixedly mounted on the bottom of the outrigger 73, a straight tube 75 fixedly connected to the bottom of the cylindrical cavity 25 facing the bottom center of the straight tube 75, a movable sleeve group 77 mounted on the bottom of the straight tube 75, the movable sleeve group 77 includes a second sleeve 772 fixedly mounted on the bottom of the straight tube 75, and also includes a first sleeve 771 fixedly mounted at the bottom center of the cylindrical cavity 25, the bottom of the first sleeve 771 is in communication with the conduit connected to the output end of the adsorption pump unit 9, the bottom of the second sleeve 772 is fixedly mounted with a recessed sleeve 773, and is movably mounted on the top of the first sleeve 771 through the recessed sleeve 773.

[0065] like Figures 1 to 7 As shown, the sorting reflux filtration mechanism 7 also includes several layers of conical hat-shaped leakage discs 72 fixedly mounted on the inner wall of the cylindrical cavity 25, and the leakage openings corresponding to the grinding stages of the multi-stage grinding stator group 24 are opened in sequence on the several layers of conical hat-shaped leakage discs 72 from top to bottom, and a hollow sleeve 71 is fixedly mounted at the center position of the circle of the several layers of conical hat-shaped leakage discs 72. The hollow sleeve 71 is movably sleeved on the outer surface of the straight tube 75 as a whole, and a magnetic coating 76 is fixedly mounted on the outer surface of the straight tube 75 at the position corresponding to each layer of conical hat-shaped leakage disc 72.

[0066] like Figures 1 to 7 As shown, the conical hat-shaped leakage disc 72 divides the interior of the cylindrical cavity 25 into several independent chambers, and a magnetic ring sleeve 78 is movably installed on the upper surface of the conical hat-shaped leakage disc 72 in each chamber, and the magnetic end on the inner annular surface of the magnetic ring sleeve 78 corresponds one-to-one with the magnetic coating 76 on the straight tube 75, and a stirring plate 79 attached to the conical hat-shaped leakage disc 72 is fixedly installed on the outer annular surface of each magnetic ring sleeve 78, and a scraper 710 is movably installed through a first sleeve 771 in the bottom chamber separated by several layers of conical hat-shaped leakage discs 72, and the top of the scraper 710 is adsorbed and corresponds to the adjacent magnetic ring sleeve 78 across the conical hat-shaped leakage disc 72, and the scraping end of the scraper 710 is attached to the bottom surface of the cylindrical cavity 25, and the bottom surface of the cylindrical cavity 25 is provided with a first connecting leak 27 leading to the interior of the hemispherical cavity 22.

[0067] Among them, the configured sorting reflux filtering mechanism 7 is divided into two independent working areas as a whole, that is, the cylindrical cavities 25 on both sides. The configured bent conduit 74 communicates with the output end of the adsorption pumping unit 9. The transferred material is discharged into the cylindrical cavities 25 on both sides through the bent conduit 74. The bent conduit 74 is located at the position of the conical funnel-shaped leakage tray 72 on the uppermost side as a whole, so that the transferred material is re-screened three times in the cylindrical cavity 25. Therefore, in order to match the multi-stage rotor disks 113 of the multi-stage grinding rotor group 11, the leakage openings of the conical funnel-shaped leakage tray 72 from top to bottom are divided into 200 microns, 100 microns, and 50 microns. The conical funnel-shaped leakage tray 72 is fixedly installed on the inner wall of the cylindrical cavity 25, and there are second communication leakage openings 28 communicating with the grinding chamber 23 on the side wall according to the divided working cavities, so that the particles in each interval can directly enter the corresponding grinding area for secondary processing.

[0068] In summary, the specific working principle of the configured sorting reflux filtering mechanism 7 is as follows:

[0069] First, the material transferred by the adsorption pumping unit 9 is discharged into the conical funnel-shaped leakage tray 72 on the highest side in the cylindrical cavity 25 through the bent conduit 74, and leaks onto the conical funnel-shaped leakage tray 72 at the bottom through the leakage opening of the conical funnel-shaped leakage tray 72 on the highest side, and so on. Each conical funnel-shaped leakage tray 72 is conical as a whole and has a certain inclination angle, which can better flow the material into the grinding chamber 23 on the side wall through the second communication leakage opening 28.

[0070] Then, by turning on the servo motor 26, the rotation of the outer extension rod 73 at the output end of the servo motor 26 drives the straight pipe 75 inside the hollow sleeve 71 to rotate. Since the magnetic adsorption coating 76 on the straight pipe 75 adsorbs and corresponds to the outer magnetic adsorption ring sleeve 78, during the rotation process, the magnetic adsorption ring sleeve 78 can be driven to control the stirring plate 79 to stir each layer of conical funnel-shaped leakage tray 72, on the one hand, improving the leakage efficiency of the material, and on the other hand, improving the efficiency of the material entering the second communication leakage opening 28.

[0071] Finally, the material leaking to the bottom of the cylindrical cavity 25 will enter the inside of the hemispherical cavity 22 again through the first communication leakage opening 27 under the scraping action of the scraper 710, and after secondary processing, a filtering closed loop is formed.

[0072] Among them, as shown in the attached drawings, the configured scraper 710 is a circular ring scraper structure provided with an extension tube as a whole. One end of the extension tube is adsorbed and corresponds to the magnetic adsorption ring sleeve 78 in the adjacent cavity through the magnetic adsorption end face. During the rotation of the magnetic adsorption ring sleeve 78 in the adjacent cavity, the scraper 710 can be driven to rotate. Therefore, in order to improve the overall stability, high-strength magnetic adsorption structures are adopted.

[0073] As Figures 1 to 7As shown, a fitting slot 123 is fixedly installed at the center position of the inner top of the frustum-shaped leak port cavity shell 122, and a magnetic suspension cleaning group 13 is movably installed through the fitting slot 123. The magnetic suspension cleaning group 13 includes a disc plate 131. An extension disc 132 is fixedly installed at the bottom of the disc plate 131. Two ultrasonic vibration heads 133 spaced 180 degrees apart are fixedly installed on the outer surface of the extension disc 132. Cavity blocks 134 are fixedly installed on the output ends of the ultrasonic vibration heads 133, and magnetic heads 135 are fixedly installed on the outer extending end faces of each cavity block 134. Two electric control magnetic units 8 corresponding to the magnetic heads 135 one by one are fixedly installed on the inner side surface of the hemispherical cavity 22.

[0074] As Figures 1 to 7 shown, the magnetic suspension cleaning group 13 further includes a reset sleeve rod 136 fixedly installed on the upper surface of the cavity block 134. A cleaning plate 137 is fixedly installed on the output end of the reset sleeve rod 136. The cleaning surface of the cleaning plate 137 is attached to the bottom of the leak port end face of the frustum-shaped leak port cavity shell 122.

[0075] Among them, the configured magnetic suspension cleaning group 13 is for cleaning the leak port on the surface of the frustum-shaped leak port cavity shell 122 on the one hand, and for vibrating the overall system by using the ultrasonic vibration heads 133 on the other hand. The specific working principle is as follows:

[0076] First of all, since the entire magnetic suspension cleaning group 13, that is, the disc plate 131, is movably installed in the fitting slot 123 of the frustum-shaped leak port cavity shell 122, during the working process, only by adsorbing the magnetic heads 135 through the electric control magnetic units 8 on both sides, the magnetic suspension cleaning group 13 will not rotate during the rotation of the frustum-shaped leak port cavity shell 122.

[0077] Then, since the entire magnetic suspension cleaning group 13 is unknown, in terms of structure, it is equivalent to the cleaning plate 137 cleaning the rotating frustum-shaped leak port cavity shell 122, that is, cleaning the leak port on the outer surface of the frustum-shaped leak port cavity shell 122. The vibration of the ultrasonic vibration heads 133 can transmit the vibration to the hemispherical cavity shell 121 and the arc-shaped stirring arm 126 through the cavity blocks 134 at the output ends of the ultrasonic vibration heads 133.

[0078] Among them, the configured cavity blocks 134 are of a solid conductor structure in the prior art to ensure the vibration transmission effect. The ultrasonic vibration heads 133 are devices capable of ultrasonic vibration in the prior art, and the reset sleeve rods 136 are structures configured with spring rods, so that the outer cleaning plate 137 is resiliently attached to the inner bottom surface of the frustum-shaped leak port cavity shell 122.
