Description

Technical Field

[0001] This application relates to the field of material centrifugation equipment technology, and in particular to a multifunctional centrifuge. Background Technology

[0002] Centrifuges play a vital role in the field of material separation, and with industrial development, the demand for material separation is increasing daily. Centrifuges utilize centrifugal force to separate substances with different specific gravities. They can generate high angular velocities, making the centrifugal force much greater than gravity, thus causing suspended solids in solutions to precipitate out, or separating the liquid phase from solid-liquid mixtures. They are widely used in many industries such as chemical, pharmaceutical, and food processing, greatly improving production efficiency and product quality.

[0003] A Chinese patent with authorization announcement number CN114210472B discloses a combined centrifuge suitable for the separation of multiple materials, including a centrifugal separation component, a drive component, and an active cleaning component. The drive component is installed at the bottom of the centrifugal separation component, and the active cleaning component is prefabricated above the centrifugal separation component. The materials are centrifuged and separated in the centrifugal separation component. When separating some highly viscous materials that are difficult to separate, the ultrasonic generator in the active cleaning component emits ultrasonic waves to actively clean the materials, causing the liquid in the materials to be separated quickly. The ultrasonic generator can be installed on the inner and outer sides of the centrifugal separation component to meet different operating conditions. The entire device has good installation and operation stability and greatly improves the range of materials that can be centrifuged.

[0004] The aforementioned technologies have the following drawbacks: Secondary cleaning of the liquid phase during solid-liquid separation is inconvenient. In actual material processing, the following situation occurs: initially, solid A and liquid B are separated, but a significant amount of liquid B remains on the surface of solid A, or even partially adsorbs liquid B. Therefore, solid A is usually removed from the centrifuge and placed in another cleaning device, where liquid C is added. Liquid C reacts with liquid B to precipitate the solution, and then the material is transferred back to the centrifuge for solid-liquid separation of liquid C and solid A. Finally, solid A is removed and dried. This material processing process is difficult to implement in traditional centrifuges, requiring the use of other equipment and frequent transfers, resulting in low processing efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] To enhance the versatility of processing functions, this application provides a multi-functional centrifuge.

[0006] A multifunctional centrifuge includes a housing, inside which a rotating drum is rotatably mounted. A centrifugal drive for driving the rotating drum is provided at the bottom of the housing. A feeding pipe and a cleaning pipe are provided at the top of the housing. The bottom openings of the feeding pipe and the cleaning pipe are both located above the top opening of the rotating drum. The housing also includes a drying module.

[0007] By adopting the above technical solution, solid A and liquid B can be injected into the drum through the self-injection pipe. Liquid B is initially separated by centrifugal drive. Then, liquid C is injected through the cleaning pipe to rinse the solid A with residual liquid B on the surface and precipitate liquid B. Then, liquid C is separated from solid A again by centrifugal drive. Finally, hot air is blown into the drum by the drying module to achieve rapid drying, which improves the versatility of processing functions.

[0008] Preferably, the top of the housing is open and has a cover, the cover is connected to a scraper, the scraper has a cleaning channel inside, and the cleaning channel is connected to a cleaning pipe.

[0009] By adopting the above technical solution, liquid C enters the cleaning channel through the self-cleaning pipe. When the drum rotates, the scraper scrapes the material on the inner wall of the drum. During the scraping, liquid C is rinsed and the material is stirred to a certain extent, which can improve the rinsing effect. Combined with the solution of setting the top of the shell with the injection pipe and the cleaning pipe, setting the bottom with the centrifugal drive, and setting the shell with the drying module, it can realize the functions of material injection, solid-liquid separation, cleaning and drying, and improve the diversity of processing functions.

[0010] Preferably, the cleaning channel is connected to a side flushing branch and a bottom flushing branch, and a control valve is provided inside the side flushing branch and the bottom flushing branch. The end opening of the side flushing branch is arranged facing the side of the drum, and the end opening of the bottom flushing branch is arranged facing the bottom of the drum.

[0011] By adopting the above technical solution, the internal cleaning channel of the scraper connected to the cover is connected to the cleaning pipe. When the drum rotates, the scraper scrapes the material and simultaneously washes and stirs it. The cleaning channel is connected to the side flushing channel and the bottom flushing channel, and both are equipped with control valves. The end opening of the side flushing channel faces the side of the drum, and the end opening of the bottom flushing channel faces the bottom of the drum. The control valves can control the opening and closing of the side flushing channel and the bottom flushing channel to achieve targeted washing of the material on the side and bottom of the drum and improve the washing effect.

[0012] Preferably, the cleaning tube is rotatably connected to the scraper, and the cleaning tube is provided with a swing drive for driving the scraper to rotate.

[0013] By adopting the above technical solution, the cleaning pipe is rotatably connected to the scraper and equipped with a swing drive, which allows the scraper to rotate, adjusting the scraping range of the scraper and the rinsing range of the cleaning fluid, thereby improving the rinsing effect. For example, after the side wall of the drum has been scraped and rinsed, the blade of the scraper can be rotated to contact the bottom of the drum by the swing drive, thereby shoveling up and rinsing the material accumulated at the bottom of the drum, increasing the change of material position, and further improving the rinsing effect.

[0014] Preferably, when the scraper swings downward to contact the bottom of the drum, the end opening of the side punch channel is oriented upward, and the end opening of the bottom punch channel is oriented towards the side wall of the drum.

[0015] By adopting the above technical solution, when the scraper swings downward to contact the bottom of the drum, the opening direction of the side flushing channel ends faces upward, and the opening direction of the bottom flushing channel ends faces the side wall of the drum. This changes the flushing direction, allowing for a more comprehensive flush of the bottom and side wall of the drum, further improving the flushing effect. It also further enhances the agitation of the material during the flushing process.

[0016] Preferably, a section of the inner wall of the side-flow branch near the end opening is provided with a vibrating fin, the vibrating fin is inclined, and a vibration gap is left between the vibrating fin and the inner wall of the side-flow branch.

[0017] By adopting the above technical solution, when the centrifuge uses the side flushing channel to wash the material inside the drum, the inclined vibrating fins with a vibration gap between them and the inner wall of the side flushing channel can cause the water flow to vibrate, realizing a pulse-type impact water flow, thereby enhancing the washing effect on the material. Combined with centrifugal drive, solid-liquid separation can be better achieved, and with the drying module, the material can be dried quickly, improving the versatility of the centrifuge's processing functions.

[0018] Preferably, an adjustment sleeve is fitted on the outer side of the drum, the adjustment sleeve is provided with a plurality of adjustment holes, the adjustment holes are adapted to the filter holes of the drum, and the drum is provided with an adjustment drive for driving the adjustment sleeve to control the degree of communication between the filter holes and the adjustment holes.

[0019] By adopting the above technical solution, an adjustment sleeve is fitted around the outside of the centrifuge drum. The adjustment hole on the adjustment sleeve is adapted to the filter hole of the drum, and an adjustment drive is set to control the degree of connection between the two. When the adjustment hole and the filter hole are not connected, the adjustment sleeve can work with the drum to accumulate a certain amount of cleaning liquid, immersing the solid material in the cleaning liquid and providing more sufficient solid-liquid reaction time.

[0020] Preferably, the drying module includes an air supply pipe, and a fan and heating wire are installed inside the air supply pipe.

[0021] By adopting the above technical solution, a fan and heating wire are installed in the air duct of the drying module in the multi-functional centrifuge, which can blow hot air into the drum to achieve rapid drying of materials and further improve the drying effect of the centrifuge processing function.

[0022] Preferably, the cleaning pipe, cleaning channel and air supply pipe are connected by a three-way valve.

[0023] By adopting the above technical solution, the connection status of the cleaning pipe, cleaning channel, and air supply pipe can be flexibly switched via a three-way valve, enabling convenient switching between feeding, cleaning, and drying functions, thus improving the operational convenience and efficiency of the multi-functional centrifuge. Furthermore, when the air supply pipe and cleaning channel are actually connected, air can be supplied while the material is agitated by a scraper, which is more conducive to material drying.

[0024] A centrifugation method based on a multifunctional centrifuge involves first injecting solid A and liquid B into the drum through a self-injection pipe, then turning on the centrifuge drive to perform preliminary separation of liquid B; then, liquid C washes the solid A with residual liquid B on the surface through a cleaning pipe, during which liquid B is precipitated; then, the centrifuge drive is used to separate liquid C from solid A again, and finally, hot air is blown into the drum by a drying module to achieve rapid drying.

[0025] By adopting the above technical solution, solid-liquid separation, liquid phase replacement and drying operations can be completed in the same centrifuge, avoiding the need to coordinate with other equipment and frequently transfer materials, thereby improving the diversity of processing functions and processing efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Through the feeding pipe, cleaning pipe and drying module, the initial solid-liquid separation, solid phase cleaning, secondary solid-liquid separation and drying operations can be completed in one centrifuge, which improves the versatility of processing functions, avoids frequent material transfer and improves processing efficiency;

[0028] 2. The cleaning channel inside the scraper is connected to the cleaning pipe. When the drum rotates, the scraper scrapes the material and simultaneously washes and agitates it, which can improve the washing effect.

[0029] 3. The adjusting sleeve and adjusting drive can control the degree of connection between the drum filter hole and the adjusting hole. When the adjusting hole and the filter hole are not connected, the adjusting sleeve can work with the drum to accumulate a certain amount of cleaning liquid, immersing the solid material in the cleaning liquid and providing more sufficient solid-liquid reaction time.

[0041] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0042] This application mainly adopts a scheme of adding a feeding pipe, a cleaning pipe and a drying module to the centrifuge, which achieves the effect of improving the diversity of the centrifuge's processing functions and improving the material processing efficiency. The following is a further detailed description of this application.

[0043] Example

[0044] Reference Figure 1The multifunctional centrifuge provided in this application embodiment includes a housing 1, a rotating drum 11, a centrifugal drive 12, a feeding pipe 13, a cleaning pipe 14, and a drying module 2. The rotating drum 11 is rotatably mounted inside the housing 1 at its center via bearings, and filter holes are provided on the sidewall of the rotating drum 11. Figure 1 (Not shown in the image) The centrifugal drive 12 at the bottom of the housing 1 is connected to the rotating drum 11 and is used to drive the rotating drum 11 to rotate. The feeding pipe 13 and the cleaning pipe 14 are located at the top of the housing 1, and the bottom openings of the feeding pipe 13 and the cleaning pipe 14 are located above the top opening of the rotating drum 11 or extend into the interior of the rotating drum 11. The drying module 2 is installed on the housing 1 and is used to supply air into the housing 1. This structure enables the centrifuge to have multiple functions such as feeding, cleaning and drying, and can complete a series of operations such as solid-liquid separation, secondary liquid cleaning and drying, which improves the versatility of processing functions, avoids frequent material transfer and improves processing efficiency.

[0045] Specifically, the shell 1, as the supporting and protective structure of the entire centrifuge, is usually made of high-strength metal materials, such as stainless steel, to ensure its structural strength and corrosion resistance. The shell 1 is generally cylindrical in shape and hollow inside, providing space for the installation and rotation of the drum 11.

[0046] The rotating drum 11 is one of the core components of the centrifuge. It is installed inside the housing 1 and can rotate around its own axis. The rotating drum 11 is usually made of a metal material, such as aluminum alloy, which has high strength and light weight. The rotating drum 11 is cylindrical in shape with an opening at the top for receiving the material injected by the feed pipe 13. Filter holes are provided on the side walls and bottom of the rotating drum 11. Figure 1 (Not shown in the image), used to pass the liquid phase through during centrifugation to achieve solid-liquid separation. The drum 11 can also be made of other materials such as ceramic to meet different application requirements.

[0047] The centrifugal drive 12 is used to drive the drum 11 to rotate, and typically consists of a motor and a transmission mechanism. The motor can be an AC motor or a DC motor, with appropriate power and speed selected according to actual needs. The transmission mechanism can be a belt drive, chain drive, or gear drive, etc., to transmit the power of the motor to the drum 11, enabling it to rotate at high speed. The centrifugal drive 12 can also adopt a direct drive method, that is, the motor is directly connected to the drum 11, reducing transmission links and improving transmission efficiency.

[0048] The injection tube 13 is located at the top of the housing 1, with its bottom opening located above the top opening of the drum 11 or extending into the drum 11. The injection tube 13 is used to inject material into the drum 11 and is typically made of plastic or metal. The diameter and length of the injection tube 13 are designed according to actual needs to ensure that the material can be smoothly injected into the drum 11. The injection tube 13 can also adopt a telescopic structure to allow adjustment according to different usage scenarios.

[0049] The cleaning pipe 14 is also located at the top of the housing 1, with its bottom opening located above the top opening of the drum 11 or extending into the drum 11. The cleaning pipe 14 is used to inject cleaning fluid into the drum 11 to clean the material. The structure and material of the cleaning pipe 14 are similar to those of the injection pipe 13, and its diameter and length are designed according to actual needs. The cleaning pipe 14 can also be equipped with multiple nozzles to improve the cleaning effect.

[0050] Reference Figure 2 The drying module 2 is mounted on the housing 1 and is used to blow hot air into the rotating drum 11 to achieve rapid drying of the material. The drying module 2 includes an air supply duct 21, a fan 22, and a heating wire 23. The air supply duct 21 is typically made of metal, with one end connected to the fan 22 and the other end extending into the rotating drum 11. The fan 22 generates airflow, and the heating wire 23 heats the air. The air heated by the heating wire 23 is then blown into the rotating drum 11 to reach a suitable temperature. The drying module 2 can also employ other heating methods, such as infrared heating.

[0051] The combination logic and effect of these components are as follows: First, solid A and liquid B are injected into the rotating drum 11 through the feed pipe 13. Then, the centrifugal drive 12 is turned on, and the rotating drum 11 rotates at high speed. Centrifugal force is used to separate liquid B through the filter holes of the rotating drum 11, achieving preliminary solid-liquid separation. Then, liquid C is used to rinse the solid A with residual liquid B on the surface through the cleaning pipe 14, and liquid B is precipitated out during the rinsing process. Finally, the centrifugal drive 12 is turned on again to separate liquid C from solid A, and hot air is blown into the rotating drum 11 by the drying module 2 to quickly dry solid A. This combination method allows the centrifuge to complete multiple operations such as solid-liquid separation, secondary liquid cleaning, and drying in one device, greatly improving processing efficiency.

[0052] Reference Figure 1 and Figure 3 Specifically, the top of the housing 1 is open and is provided with a cover 10. The cover 10 is connected to a scraper 3. The scraper 3 is provided with a cleaning channel 30 inside, and the cleaning channel 30 is connected to the cleaning pipe 14.

[0053] The cover 10 is typically made of metal or plastic and its shape is adapted to the top opening of the shell 1 to seal the top opening of the shell 1 and prevent material from splashing out during centrifugation. A sealing connection, such as a rubber gasket, can be used between the cover 10 and the shell 1 to ensure a tight seal. The cover 10 may also be equipped with an observation window to allow operators to observe the interior of the drum 11.

[0054] The scraper 3 is attached to the cover 10 and is made of a metal material, such as stainless steel, which has high hardness and wear resistance. The scraper 3 has a cleaning channel 30 inside, which is connected to the cleaning pipe 14, allowing liquid C to enter the cleaning channel 30 from the cleaning pipe 14. During the actual rinsing process, the drum 11 rotates, and the scraper 3 scrapes the material on the inner wall of the drum 11. At the same time, liquid C rinses the material through the cleaning channel 30 and, to some extent, agitates the material, thus improving the rinsing effect. The scraper 3 can also be made of an elastic material to better conform to the inner wall of the drum 11 and improve the scraping effect.

[0055] The cleaning channel 30 is an internal channel structure of the scraper 3 used to transport the cleaning fluid. The shape and size of the cleaning channel 30 are designed according to the structure of the scraper 3 and the cleaning requirements to ensure smooth flow of the cleaning fluid. The cleaning channel 30 and the cleaning pipe 14 can be connected by a sealed connection, such as a threaded connection or a clamp connection, to prevent leakage of the cleaning fluid. The cleaning channel 30 can also be provided with multiple branches to expand the cleaning range.

[0056] The combination logic and effect of these components are as follows: when it is necessary to clean the material inside the drum 11, liquid C enters the cleaning channel 30 from the cleaning pipe 14, and then the material on the inner wall of the drum 11 is thoroughly cleaned by the scraping of the scraper 3 and the rinsing of the cleaning liquid, which improves the cleaning effect and further enhances the processing function of the centrifuge.

[0057] Specifically, the cleaning channel 30 is connected to a side flushing branch channel 31 and a bottom flushing branch channel 32. Both the side flushing branch channel 31 and the bottom flushing branch channel 32 are equipped with control valves (not shown in the figure). The end opening of the side flushing branch channel 31 is set towards the side of the drum 11, and the end opening of the bottom flushing branch channel 32 is set towards the bottom of the drum 11.

[0058] Side flushing channels 31 and bottom flushing channels 32 are branch structures of the cleaning channel 30, used to flush the side walls and bottom of the drum 11 respectively. Side flushing channels 31 and bottom flushing channels 32 are typically made of plastic or metal, and their diameter and length are designed according to actual needs. The end opening of the side flushing channel 31 faces the side of the drum 11, and the end opening of the bottom flushing channel 32 faces the bottom of the drum 11, thus enabling targeted flushing of different parts of the drum 11. Side flushing channels 31 and bottom flushing channels 32 can also have an adjustable angle structure for adjustment according to different usage scenarios.

[0059] Control valves are installed inside the side flushing channel 31 and the bottom flushing channel 32 to control the flow rate of the cleaning fluid. The control valves can be solenoid valves, selected according to actual needs. By adjusting the control valves, the flow rate of the cleaning fluid in the side flushing channel 31 and the bottom flushing channel 32 can be controlled separately, achieving different intensities of rinsing for different parts of the drum 11. The control valves can also be connected to a control system for automated control.

[0060] The combination logic and effect of these components are as follows: During the cleaning process, the flow rate of the cleaning fluid in the side flushing channel 31 and the bottom flushing channel 32 can be controlled by the control valve to perform targeted rinsing on the side wall and bottom of the drum 11, which improves the flexibility and effect of cleaning and further enhances the processing function of the centrifuge.

[0061] Reference Figure 3 and Figure 4 Specifically, the cleaning tube 14 is rotatably connected to the scraper 3, and the cleaning tube 14 is equipped with a swing drive (not shown in the figure) for driving the scraper 3 to rotate. The swing drive, which drives the scraper 3 to rotate, is typically composed of a motor and a transmission mechanism. The motor can be a stepper motor or a servo motor, with appropriate precision and speed selected according to actual needs. The transmission mechanism can be a gear drive, chain drive, or belt drive, etc., to transmit the power of the motor to the scraper 3, causing it to swing. The swing drive can also adopt a direct drive method, that is, the motor is directly connected to the scraper 3, reducing transmission links and improving transmission precision.

[0062] This structure allows the scraper 3 to swing under the action of the oscillating drive, expanding the scraping range of the scraper 3 and further improving the cleaning effect. During the cleaning process, the oscillating drive drives the scraper 3 to swing, and the scraper 3 scrapes the material on the inner wall of the drum 11 more comprehensively. At the same time, the cleaning fluid rinses the material through the cleaning channel 30, improving the uniformity and effect of the cleaning.

[0063] Specifically, refer to Figure 4 When the scraper 3 swings downwards to contact the bottom of the drum 11, the end opening of the side flushing channel 31 faces upwards, and the end opening of the bottom flushing channel 32 faces the side wall of the drum 11. This arrangement allows the side flushing channel 31 and the bottom flushing channel 32 to agitate and rinse the material separately when the scraper 3 contacts the bottom of the drum 11, achieving efficient cleaning. When the scraper 3 swings downwards to contact the bottom of the drum 11, the end opening of the side flushing channel 31 faces upwards, and the cleaning liquid is sprayed upwards to rinse the material on the top of the drum 11; the end opening of the bottom flushing channel 32 faces the side wall of the drum 11, and the cleaning liquid is sprayed towards the side wall to rinse the material on the side wall of the drum 11, improving the cleaning effect.

[0064] Reference Figure 5Specifically, a section of the inner wall of the side flushing channel 31 near the end opening is equipped with vibrating fins 33. The vibrating fins 33 are inclined, and a vibration gap 34 is left between the vibrating fins 33 and the inner wall of the side flushing channel 31. The vibrating fins 33 are typically made of metal, such as stainless steel, and are sheet-shaped, inclinedly positioned on the inner wall of the side flushing channel 31 near the end opening. The vibration gap 34 between the vibrating fins 33 and the inner wall of the side flushing channel 31 allows the cleaning fluid to impact the vibrating fins 33 as it passes through the side flushing channel 31, causing them to vibrate. This vibration creates turbulence in the cleaning fluid, improving the cleaning effect. The vibrating fins 33 can also be made of other materials, such as plastic, to reduce weight.

[0065] Reference Figure 1 and Figure 6 Specifically, an adjusting sleeve 15 is fitted onto the outer side of the rotating drum 11. The adjusting sleeve 15 has several adjusting holes 150, which are adapted to the filter holes of the rotating drum 11. The rotating drum 11 is equipped with an adjusting drive 16 for driving the adjusting sleeve 15 to control the degree of connection between the filter holes and the adjusting holes 150. The adjusting sleeve 15, typically made of metal such as aluminum alloy, is fitted onto the outer side of the rotating drum 11 and its shape is adapted to the rotating drum 11. The adjusting sleeve 15 has several adjusting holes 150, the position and size of which are adapted to the filter holes of the rotating drum 11. The adjusting drive 16 drives the adjusting sleeve 15 to rotate, thereby controlling the degree of connection between the filter holes and the adjusting holes 150. The adjusting drive 16 typically consists of a motor and a transmission mechanism, and its working principle is similar to that of the centrifugal drive 12. Through the adjustment sleeve 15 and the adjusting drive 16, the degree of connection between the filter holes and the adjusting holes 150 can be adjusted according to different materials and processing requirements, thereby controlling the separation speed and effect of the liquid phase. For example, when it is necessary to react and displace liquid B on the surface of solid A with liquid C, the filter holes can be sealed with adjusting sleeve 15 to achieve water storage. After a certain amount of liquid C has accumulated inside the drum 11 and adjusting sleeve 15, solid A can be easily immersed in liquid C, thus fully realizing the reaction between liquid B and liquid C. Adjusting sleeve 15 can also adopt other retractable structures to achieve more flexible adjustment.

[0066] Reference Figure 1Specifically, the cleaning pipe 14, cleaning channel 30, and air supply pipe 21 are connected by a three-way valve 17. The three-way valve 17 controls the connection between the cleaning pipe 14, cleaning channel 30, and air supply pipe 21. The three-way valve 17 is typically made of metal and has three ports, which connect to the cleaning pipe 14, cleaning channel 30, and air supply pipe 21 respectively. By operating the three-way valve 17, the connection between the cleaning pipe 14 and cleaning channel 30, and between the cleaning channel 30 and air supply pipe 21, can be achieved, thus enabling different function switching. The three-way valve 17 can also be controlled electrically or pneumatically to achieve automated operation. Therefore, during rinsing, cleaning liquid can be sprayed from the scraper 3, and during drying, hot air can also be sprayed from the scraper 3, achieving simultaneous rinsing or drying of the material while stirring it, further improving processing efficiency.

[0067] The implementation principle of this embodiment is as follows: This multi-functional centrifuge integrates multiple functions such as feeding, cleaning, and drying into one device through a reasonable structural design. In actual use, material is first injected into the drum 11 through the feeding pipe 13, and preliminary solid-liquid separation is achieved using the centrifugal drive 12. Then, cleaning fluid is injected through the cleaning pipe 14 to clean the material, while the cleaning effect is improved by structures such as the scraper 3, side flushing channels 31, and bottom flushing channels 32. Finally, hot air is blown into the drum 11 using the drying module 2 to achieve rapid drying of the material. This integrated design avoids the problem of traditional centrifuges requiring coordination with other equipment and frequent transfer when processing materials, greatly improving processing efficiency, enhancing the diversity of processing functions, and meeting the needs of different users. It represents a significant improvement and innovation in existing centrifuge technology.

[0068] This application also provides a centrifugation method based on a multifunctional centrifuge, including the following steps:

[0069] S1. First, solid A and liquid B are injected into the drum 11 through the feed pipe 13. Then, the centrifugal drive 12 is turned on to perform preliminary separation of liquid B. In this step, the operator injects the solid A and liquid B to be separated into the drum 11 through the feed pipe 13. Then, the centrifugal drive 12 is started, and the drum 11 begins to rotate at high speed. Centrifugal force is used to separate liquid B through the filter holes of the drum 11, achieving preliminary solid-liquid separation. During the operation, the appropriate centrifugal speed and time need to be selected according to the properties of the materials and the processing requirements.

[0070] S2, then liquid C is used to rinse solid A, which has liquid B residue on its surface, through cleaning pipe 14, causing liquid B to precipitate out during the rinsing process. After initial separation, solid A with liquid B residue remains inside the rotating drum 11. At this point, liquid C is injected into the rotating drum 11 through cleaning pipe 14, and liquid C rinses solid A. During the rinsing process, liquid C reacts with the liquid B residue on the surface of solid A, causing liquid B to precipitate out. In this step, it is necessary to control the injection volume and flow rate of liquid C to ensure the rinsing effect. In addition to rinsing, soaking can also be used to significantly extend the reaction time between liquid B and liquid C.

[0071] S3, centrifugal drive 12 separates liquid C from solid A. After rinsing, centrifugal drive 12 is restarted, and drum 11 rotates at high speed. Centrifugal force forces liquid C through the filter holes of drum 11, thus separating liquid C from solid A. Similarly, the appropriate centrifugal speed and time need to be selected according to the properties of the material and the processing requirements.

[0072] S4. Finally, hot air is blown into the rotating drum 11 by the drying module 2 to achieve rapid drying. After the C liquid and A solid separate, the drying module 2 is started, and the fan 22 blows the air heated by the heating wire 23 into the rotating drum 11 to quickly dry the A solid. During the drying process, the temperature and wind speed of the hot air need to be controlled to ensure the drying effect.

[0073] The implementation principle of this embodiment is as follows: This centrifugation method fully utilizes the various functions of a multi-functional centrifuge, and through a reasonable arrangement of steps, completes multiple operations such as solid-liquid separation, secondary liquid-phase cleaning, and drying within a single device. This avoids the problem of frequent material transfer required in traditional methods, greatly improving processing efficiency. Simultaneously, by precisely controlling the operating parameters of each step, the processing quality of the material can be ensured, meeting the needs of different users. This represents a significant improvement and innovation to existing centrifugation methods.

[0075] Reference Figure 7 The difference between Embodiment 2 and Embodiment 1 is that the cleaning pipe 14, the air supply pipe 21, and the scraper 3 are independently configured. Its working process is as follows:

[0076] First, solid A and liquid B are injected into the drum 11 through the feed pipe 13. Then, the centrifugal drive 12 is turned on to perform preliminary separation of liquid B. Centrifugal force is used to separate liquid B through the filter holes of the drum 11, thus achieving preliminary solid-liquid separation.

[0077] Then, liquid C is used to rinse solid A, which has liquid B residue on its surface, through cleaning tube 14. During the rinsing process, liquid C reacts with the liquid B residue on the surface of solid A, causing liquid B to precipitate out.

[0078] Furthermore, by using centrifugal drive 12, centrifugal force is used to separate liquid C through the filter holes of the rotating drum 11, thereby achieving the separation of liquid C and solid A.

[0079] Finally, the drying module 2 blows hot air into the drum 11, and the fan 22 blows the air heated by the heating wire 23 into the drum 11 to quickly dry solid A.

[0080] In another scenario, solid A and a mixture containing liquid B can be injected into the drum 11. After centrifugation, liquid B is separated and discharged. Then, liquid C is injected through the cleaning pipe 14 to mix with solid A. The mixture of solid A and liquid C is then discharged, achieving the replacement of liquid B with liquid C within solid A. During the replacement process, centrifugal drive 12 is used for agitation. In contrast, in conventional technology, solid A mixed with liquid B is centrifuged to separate liquid B, solid A is then cleaned and discharged by a scraper, and then solid A is added to a mixer to mix with liquid C for replacement of liquid B. This reduces the cleaning and unloading work of solid A, significantly improving efficiency.

[0081] After the replacement is completed, centrifugal drive 12 is used to separate solid A containing liquid C from liquid B that has precipitated out, thus improving the ease of processing.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
