Description

Technical Field

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

[0002] As an efficient wet material fine processing equipment, the colloid mill is widely used in the fields of food, medicine and chemical industry. Its working principle is based on the shearing force, friction 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 of the rotor speed 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 need to be 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 be initially classified, 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 filtering 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 speed to cope with the change of 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.

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) This scheme constructs a full-process closed-loop system from grinding to screening and then grinding through the dynamic matching design of multi-stage grinding stators and sorting reflux filtration mechanisms. 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 plate according to the three levels of rough shearing, fine grinding and homogenization, and accurately returned to the corresponding grinding gap through the tangentially connected leakage port, realizing the real-time synchronous adjustment of the screening accuracy and the grinding parameters, avoiding the repeated processing caused by the disconnection between the traditional external screen and the dynamic grinding parameters.

In particular, the magnetic suspension cleaning group uses the cooperation of the magnetic suction head and the electric-controlled magnetic suction unit to transmit ultrasonic vibration to the entire sorting system while maintaining the static cleaning plate to continuously scrape the leak hole residue, thus overcoming the technical problem that the traditional flat screen plate is easy to harden in high-viscosity materials.

[0019] (3) The dynamic stirring and closed-loop reflux mechanism driven by magnetic attraction significantly improves the sorting accuracy and system stability. The sorting reflux mechanism uses a servo motor-driven straight tube magnetic coating and a magnetic ring sleeve to drive the multi-stage bamboo hat-shaped leakage plate to rotate and stir synchronously, so that the particles are screened in layers under the synergistic effect of centrifugal force and magnetic scraper. The unqualified particles return to the primary separation module through the first connecting leakage port to form a closed loop, and the scraper assembly removes the residual particles at the bottom through magnetic attraction linkage.

[0024] The following is a detailed description of a linkage filtering device suitable for a colloid mill provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be adopted by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 7As shown, an embodiment of the present invention provides a linkage filtering device suitable for a colloid mill, comprising a main frame base 1, a linkage filtering mechanism 2 and a driving motor unit 5 are fixedly installed on both sides of the upper surface of the main frame base 1, the linkage filtering mechanism 2 comprises a cylindrical cavity 21, a hemispherical cavity 22 which is integrally arranged inside the main frame base 1 is fixedly installed at the bottom of the cylindrical cavity 21, a multi-stage grinding rotor group 11 extending inside the cylindrical cavity 21 is arranged inside the hemispherical cavity 22, and a primary separation leakage cavity module 12 which is integrally arranged in the hemispherical cavity 22 is also arranged at the bottom of the multi-stage grinding rotor group 11; A grinding chamber 23 is provided inside the cylindrical cavity 21, and a multi-stage grinding stator group 24 corresponding to the multi-stage grinding rotor group 11 is fixedly installed on the inner wall of the grinding chamber 23. Two groups of cylindrical cavities 25 located outside the grinding chamber 23 and 180 degrees apart are also provided on the side end of the cylindrical cavity 21, and a sorting reflux filtering mechanism 7 is arranged inside each cylindrical cavity 25; Among them, the sorting reflux filtration mechanism 7 as a whole is provided with different sorting layers corresponding to the grinding particle size of the multi-stage grinding stator group 24 from top to bottom, and a second connecting leak 28 is opened on the side wall of the cylindrical cavity 25 at the position where each sorting layer is tangent to the grinding chamber 23, so as to return the sorted particles to the multi-stage grinding stator group 24 of the corresponding grinding level for secondary grinding.

[0026] In order to solve the problem that the colloid mill system in the prior art cannot perform particle level matching reflux reprocessing on the processed granular materials, the above technical solution is now adopted to solve the problem. The above technical solution is mainly composed 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 various components. The prior art generally adopts a structure composed of high-rigidity cast iron and built-in flow channels, and the built-in flow channels are several channels for conveying granular materials; the configured linkage filtering mechanism 2 includes a cylindrical cavity 21 and a hemispherical cavity 22, wherein the cylindrical cavity 21 is used for colloid mill processing, which includes a multi-stage milling rotor group 11 and a multi-stage milling stator group 24. The poured granular material is processed by the shearing rotation of the multi-stage milling rotor group 11 and the multi-stage milling stator group 24. It is defined as multi-stage because in the actual processing process, especially for particle-level materials, they will be divided into three levels from rough shearing to fine grinding and then to homogenization. Therefore, for the multi-stage milling rotor group 11 and the multi-stage milling stator group 24, the specific manifestation is the difference in tooth shape and gap design. The classification of the stator and rotor will be described in detail at the corresponding component positions below. The hemispherical cavity 22 is equivalent to opening another cavity at the bottom of the processing end, so that the granular material that has undergone three-stage grinding can be initially sorted in the cavity through the initial sorting cavity module 12, and the materials that meet the particle grade are discharged, while those that do not meet the requirements are transported to the cylindrical cavity 25 on both sides. Through the sorting reflux filtering mechanism 7 configured in the cylindrical cavity 25, different particles are transported to the gaps of different rotor stages according to the three-stage division standards of rough shearing, fine grinding and homogenization, and the reflux reprocessing operation matching the particle grade is carried out. The division of the corresponding sorting reflux filtering mechanism 7 will be specifically described and analyzed in the following specific components.

[0027] like Figures 1 to 7 As shown, the multi-stage grinding rotor group 11 includes a support bracket 111 fixedly mounted on the top side wall of the hemispherical cavity 22, and a gear sleeve 112 coaxial with the grinding chamber 23 is movably mounted on the surface of the support bracket 111. Two third connecting leaks 29 are opened on the side of the hemispherical cavity 22 facing the drive motor unit 5, and the output end of the drive motor unit 5 is meshingly mounted with a linkage track sleeve 6, which is sealed and penetrated into the interior of the hemispherical cavity 22 through the third connecting leak 29 and meshingly sleeved on the gear sleeve 112. The upper surface of the gear sleeve 112 is fixedly mounted as a whole and is placed inside the grinding chamber 23, and a multi-stage rotor disc 113 corresponding to each grinding stage of the multi-stage grinding stator group 24.

[0028] Among them, the configured multi-stage grinding rotor group 11 mainly includes a multi-stage rotor disk 113, and the multi-stage rotor disk 113 is movably installed in the grinding chamber 23 through the gear sleeve 112. The configured support bracket 111 is a structure of the support sleeve. During the working process, the output end of the driving motor unit 5 is rotated to drive the linkage track sleeve 6 to rotate synchronously, and the linkage track sleeve 6 is meshed with the gear sleeve 112. Therefore, the gear sleeve 112 is controlled to rotate during the operation of the driving motor unit 5, so that the multi-stage rotor disk 113 on the upper surface of the gear sleeve 112 is attached to the multi-stage grinding stator group 24 for multi-stage grinding processing. The division of the grinding stages is as follows: Rough shear stage: The outer surface of the rotor is a mace-shaped tooth shape, and the teeth are arranged at a 45-degree angle as a whole; the outer surface of the stator is a serrated groove.

[0029] Fine grinding grade: The outer surface of the rotor is a helical tooth structure with an overall helical angle of 30 degrees; the outer surface of the stator is a honeycomb microporous groove.

[0030] Homogenizing stage: The outer surface of the rotor is smooth with tooth patterns, and the overall tooth patterns are a smooth transition of 10 degrees; the outer surface of the stator is mirror polished.

[0031] Specifically, the division of the set grinding levels can be adaptively adjusted according to the actual grinding object. For example, in the actual processing process, the texture of the processing object can be felt, and the tooth depth of the rough shearing level tooth shape, the tooth depth of the fine grinding level bevel teeth, and the tooth spacing of the homogenizing level smooth tooth pattern can be changed. The purpose is to make the particle size of the broken corn particles to 100 to 200 microns in the rough shearing stage, that is, the stage of releasing starch and fiber, and the particle size of the broken corn particles to 50 to 100 microns in the fine grinding stage, that is, the stage of breaking the protein and starch complex, and the particle size of the broken corn particles to be less than 50 microns in the homogenizing stage, that is, the stage of eliminating the shear marks on the particle surface, and through the homogenizing stage, it also meets the standard for entering the finished product tank. The permanent magnet direct drive motor in the prior art outside the configured drive motor unit 5 can achieve precise matching of speed and torque during the processing process.

[0032] like Figures 1 to 7As shown, the initial leakage cavity module 12 includes a truncated cone leakage cavity shell 122 fixedly mounted on the bottom surface of the gear sleeve 112, the bottom surface of the truncated cone leakage cavity shell 122 is fixedly connected with a hemispherical cavity shell 121, the hemispherical cavity shell 121 is concentric with the hemispherical cavity body 22, the upper surface of the truncated cone leakage cavity shell 122 is circumferentially provided with a plurality of leakage openings for standard particle grade materials to pass through, a discharge opening 124 for discharging standard particle grade materials is provided at the middle position of the bottom of the hemispherical cavity shell 121, and a discharge pipe 125 is fixedly mounted on the outer side of the discharge opening 124, the discharge pipe 125 passes through the hemispherical cavity body 22 as a whole, and a first reserved circular opening 211 for the discharge pipe 125 to pass through is provided at the bottom position of the hemispherical cavity body 22, and a discharge leakage opening 4 passing through the main frame base 1 is fixedly mounted on the passing end.

[0033] The hemispherical cavity shell 121 and the truncated cone-shaped leak cavity shell 122 are integrated into one structure. The granular material falling from the grinding chamber 23 falls on the surface of the truncated cone-shaped leak cavity shell 122. The truncated cone-shaped leak cavity shell 122 is fixedly connected to the gear sleeve 112. When the gear sleeve 112 rotates, the truncated cone-shaped leak cavity shell 122 can also rotate with it, so that the material falling on the surface of the truncated cone-shaped leak cavity shell 122 is accelerated to pass through the leak, and the truncated cone-shaped leak cavity shell 122 is The leakage on the surface is set to be less than 50 microns, that is, the particle size that can be discharged. Specifically, the granular material smaller than 50 microns falling from the grinding bin 23 enters the interior of the hemispherical cavity shell 121, and is discharged to the discharge leakage port 4 through the discharge pipe 125 at the bottom of the hemispherical cavity shell 121, and is discharged from the discharge leakage port 4. The particles that do not pass through the truncated cone leakage cavity shell 122 will fall along the truncated cone leakage cavity shell 122 to the outside of the hemispherical cavity shell 121 for initial classification.

[0034] like Figures 1 to 7 As shown, there is a gap between the hemispherical cavity 22 and the hemispherical cavity shell 121, so that non-standard particle-grade materials that have not passed through the truncated cone-shaped leakage cavity shell 122 can leak into the gap along the outer surface of the truncated cone-shaped leakage cavity shell 122. An outer arc cavity 210 is provided at the bottom of the outer wall of the hemispherical cavity 22, and a leakage groove 212 is provided at the position of the outer arc cavity 210 near the discharge pipe 125. Both side ends of the outer arc cavity 210 are provided with reserved conduit openings 213 that are connected to the cylindrical cavity 25 directly above, and a second reserved circular opening 214 is provided on the outer wall of each reserved conduit opening 213, and an adsorption pump unit 9 is fixedly installed through the second reserved circular opening 214, and a conveying conduit 10 extending from the bottom of the outer arc cavity 210 near the outer wall of the discharge pipe 125 is fixedly installed on the adsorption end of the adsorption pump unit 9.

[0035] 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 mentioned above, the particles that have not passed through the truncated cone-shaped leakage cavity shell 122 will fall along the truncated cone-shaped leakage 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 leakage slot 212. Since the hemispherical cavity shell 121 and the hemispherical cavity 22 are both hemispherical, in the process of the particles passing through It will be easier to add it to the bottom of the sphere, that is, the outer arc cavity 210, and the outer arc cavity 210 is configured as a cavity structure in the shape of an arc. Both sides of the cavity are configured with adsorption pump units 9 for transferring particles that do not meet the processing standards. Through the conveying conduit 10 fixedly installed on the adsorption end of the adsorption pump unit 9 and extending to the bottom of the outer arc cavity 210 near the outer wall of the discharge pipe 125, the particles entering the outer arc cavity 210 are adsorbed and transferred to the cylindrical cavities 25 on both sides for real-time sorting and reflux filtration. The configured adsorption pump unit 9 is a pump structure in the prior art that can stably transport powder and slurry, such as pneumatic diaphragm pumps, vacuum adsorption machines and other equipment. And in order to ensure the sealing performance of the first reserved circular port 211 of the device during operation, a sealing ring is provided at the position where the discharge pipe 125 contacts the first reserved circular port 211.

[0036] like Figures 1 to 7 As shown, an arc-shaped stirring arm 126 extending into the gap between the hemispherical cavity 22 and the hemispherical cavity shell 121 is fixedly installed on the outer wall of the discharge pipe 125, the inner arc side of the arc-shaped stirring arm 126 is in contact with the outer wall of the hemispherical cavity shell 121, and the outer arc side of the arc-shaped stirring arm 126 is in contact with the inner wall of the hemispherical cavity 22, the conduit connected to the output end of the adsorption pump unit 9 is connected to the bottom center position of the cylindrical cavity 25 through a reserved conduit opening 213, and 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, and a feed funnel 3 is fixedly installed on the upper surface of the cylindrical cavity 21.

[0037] Among them, the configured arc-shaped stirring arm 126 is an integrated structure with the discharge pipe 125, and the whole is in the shape of a comb ruler. In the actual working process, in order to improve the fluidity of the particles falling from the grinding bin 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, the rotational force of the hemispherical cavity shell 121 is utilized to control the arc-shaped stirring arm 126 to stir in the gap between the hemispherical cavity shell 121 and the hemispherical cavity 22, thereby improving the stability of the entire system. The inner arc side of the arc-shaped stirring arm 126 is emphasized to fit with the outer wall of the hemispherical cavity shell 121, and the outer arc side of the arc-shaped stirring arm 126 is emphasized to fit with the inner wall of the hemispherical cavity shell 121, so that the arc-shaped stirring arm 126 can transmit the vibration force through the mutual fitting relationship during the subsequent vibration process, so that the granular material can be accompanied by vibration during the processing and transportation process to avoid the occurrence of fine particle agglomeration.

[0038] In summary, the specific working principle of the configured initial separation leakage cavity module 12 is: First, the material to be processed is poured into the cylindrical cavity 21 through the feed funnel 3, and the drive motor unit 5 is turned on. In the process of the linked track sleeve 6 at the output end of the drive motor unit 5 pulling the gear sleeve 112 to rotate, the multi-stage rotor disc 113 can be controlled to rotate at high speed inside the grinding chamber 23, and cooperate with the multi-stage grinding stator group 24 on the inner wall of the grinding chamber 23, and the poured material is subjected to multi-stage grinding treatment according to the multi-stage grinding effect from top to bottom.

[0039] Then, the ground particles fall from the grinding bin 23 and enter the hemispherical cavity 22. Materials that meet the required standard particle grade enter the interior of the hemispherical cavity shell 121 through the leakage of the truncated cone leakage cavity shell 122, and are discharged through the discharge pipe 125 at the bottom of the hemispherical cavity shell 121. Materials that cannot pass through the leakage of the truncated cone leakage cavity shell 122 leak into the gap between the hemispherical cavity shell 121 and the hemispherical cavity 22, and are stirred in real time at high speed by the arc-shaped stirring arm 126, and finally converge into the outer arc cavity 210 through the leakage slot 212.

[0040] Finally, the particles entering the outer arc cavity 210 are adsorbed by the adsorption pump unit 9 at the second reserved circular opening 214, and are transported outward through the conveying conduit 10 at the adsorption end of the adsorption pump unit 9 to the interior of the cylindrical cavity 25, that is, enter the processing area of ​​the sorting reflux filtration mechanism 7. The whole process is carried out simultaneously 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. The stability of material transportation is increased while ensuring the integrity of the transportation end.

[0041] like Figures 1 to 7As 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 facing the bottom center of the cylindrical cavity 25 fixedly connected to the bottom of the curved conduit 74, a movable sleeve group 77 installed at the bottom of the straight tube 75, the movable sleeve group 77 includes a second sleeve 772 fixedly mounted at 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 connected to 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.

[0042] like Figures 1 to 7 As shown, the sorting reflux filtration mechanism 7 also includes a plurality of layers of conical-hat-shaped leakage discs 72 fixedly mounted on the inner wall of the cylindrical cavity 25, and the plurality of layers of conical-hat-shaped leakage discs 72 from top to bottom are sequentially provided with leakage openings corresponding to the grinding stages of the multi-stage grinding stator group 24, and a hollow sleeve 71 is fixedly mounted at the center position of the plurality of layers of conical-hat-shaped leakage discs 72, and the hollow sleeve 71 is integrally movably sleeved on the outer surface of the straight tube 75, 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.

[0043] like Figures 1 to 7 As shown, the conical-hat-shaped drain disc 72 divides the interior of the cylindrical cavity 25 into several independent chambers, and a magnetic annular sleeve 78 is movably installed on the upper surface of the conical-hat-shaped drain disc 72 located in each chamber, and the magnetic end on the inner annular surface of the magnetic annular 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 drain disc 72 is fixedly installed on the outer annular surface of each magnetic annular sleeve 78, and a scraper 710 is movably installed in the bottom chamber separated by several layers of conical-hat-shaped drain discs 72 through a first sleeve 771, and the top of the scraper 710 is adsorbed and corresponding to the adjacent magnetic annular sleeve 78 through the conical-hat-shaped drain 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.

[0044] Among them, the configured sorting reflux filtration mechanism 7 is divided into two independent working areas as a whole, namely the cylindrical cavities 25 on both sides, and the configured curved conduit 74 is connected to the output end of the adsorption pump unit 9. The transferred material is discharged into the cylindrical cavities 25 on both sides through the curved conduit 74, and the curved conduit 74 is located as a whole at the position of the uppermost conical lid-shaped leakage disk 72, so that the transferred material is re-screened in the cylindrical cavity 25 through three stages. Therefore, in order to match the multi-stage rotor disk 113 of the multi-stage grinding rotor group 11, its conical lid-shaped leakage disk 72 has leakage openings from top to bottom divided into 200 microns, 100 microns and 50 microns. The conical lid-shaped leakage disk 72 is fixedly installed on the inner wall of the cylindrical cavity 25, and between the grinding chamber 23 of the side wall, according to the divided working cavity, a second connecting leakage opening 28 is provided, so that the particles in each interval can directly enter the corresponding grinding area for secondary processing.

[0045] In summary, the specific working principle of the configured sorting reflux filtering mechanism 7 is: First, the material transferred by the adsorption pump unit 9 is discharged to the conical leakage plate 72 on the highest side of the cylindrical cavity 25 through the curved conduit 74, and then leaks out through the leakage port of the conical leakage plate 72 on the highest side onto the conical leakage plate 72 at the bottom, and so on. Each conical leakage plate 72 is conical in shape as a whole and has a certain inclination angle, so that the material can flow into the grinding chamber 23 on the side wall through the second connecting leakage port 28.

[0046] Then, by turning on the servo motor 26, the extension rod 73 at the output end of the servo motor 26 rotates, driving the straight tube 75 inside the hollow sleeve 71 to rotate. Since the magnetic coating 76 on the straight tube 75 is adsorbed and corresponds to the outer magnetic ring sleeve 78, during the rotation process, the magnetic ring sleeve 78 can be driven to control the stirring plate 79 to stir each layer of the bamboo hat-shaped leakage plate 72, thereby improving the leakage efficiency on the one hand and the material entering the second connecting leakage port 28 on the other hand.

[0047] Finally, the material leaking out of the bottom of the cylindrical cavity 25 will re-enter the interior of the hemispherical cavity 22 through the first communicating leak 27 under the scraping action of the scraper 710, and undergo secondary processing to form a filtering closed loop.

[0048] Among them, as shown in the accompanying drawings, the configured scraper 710 is a circular scraper structure with an extension tube. One end of the extension tube is adsorbed to the magnetic ring sleeve 78 in the adjacent cavity through the magnetic end face. During the rotation of the magnetic ring sleeve 78 in the adjacent cavity, the scraper 710 can be driven to rotate. Therefore, in order to improve the overall stability, a high-strength magnetic structure is adopted.

[0049] like Figures 1 to 7As shown, a fitting slot 123 is fixedly installed at the inner top center position of the truncated cone-shaped leakage cavity shell 122, and a magnetic suspension cleaning group 13 is movably installed through the fitting slot 123, and the magnetic suspension cleaning group 13 includes a disc plate 131, and an extended disc 132 is fixedly installed at the bottom of the disc plate 131, and two groups of ultrasonic vibrators 133 separated by 180 degrees are fixedly installed on the outer surface of the extended disc 132, and a cavity block 134 is fixedly installed on the output end of the ultrasonic vibrator 133, and a magnetic suction head 135 is fixedly installed on the extended end surface of each cavity block 134, and two groups of electrically controlled magnetic suction units 8 corresponding to the magnetic suction heads 135 are fixedly installed on the inner wall side of the hemispherical cavity 22.

[0050] like Figures 1 to 7 As shown, the magnetic suspension cleaning group 13 also includes a reset sleeve rod 136 fixedly mounted on the upper surface of the cavity block 134, and a cleaning plate 137 is fixedly mounted on the output end of the reset sleeve rod 136, and the cleaning surface of the cleaning plate 137 is attached to the bottom of the leakage end surface of the truncated cone-shaped leakage cavity shell 122.

[0051] The magnetic suspension cleaning group 13 is configured to clean the leak on the surface of the truncated cone-shaped leak cavity shell 122, and to vibrate the entire system using the ultrasonic vibration head 133. The specific working principle is as follows: Firstly, since the magnetic suspension cleaning group 13 as a whole, that is, the disc plate 131 is movably installed in the fitting slot 123 of the truncated cone-shaped leakage cavity shell 122, it is only necessary to adsorb the magnetic suction head 135 through the electrically controlled magnetic suction units 8 on both sides during operation, so that the magnetic suspension cleaning group 13 does not rotate during the rotation of the truncated cone-shaped leakage cavity shell 122.

[0052] Then, since the magnetic suspension cleaning group 13 is unknown as a whole, in terms of structure, it is equivalent to the cleaning plate 137 cleaning the rotating truncated cone-shaped leakage cavity shell 122, that is, cleaning the leakage on the outer surface of the truncated cone-shaped leakage cavity shell 122, and the vibration of the ultrasonic vibrator 133 can be transmitted to the hemispherical cavity shell 121 and the arc-shaped stirring arm 126 through the cavity block 134 at the output end of the ultrasonic vibrator 133.

[0053] Among them, the configured cavity block 134 is a solid conductor structure in the prior art to ensure the effect of vibration transmission, the ultrasonic vibrator 133 is a device capable of ultrasonic vibration in the prior art, and the reset sleeve rod 136 is a structure equipped with a spring rod, so that the outer cleaning plate 137 is resiliently attached to the inner bottom surface of the truncated cone-shaped leakage cavity shell 122.
