With the advancement of science and technology and the development of industry, especially in the chemical, pharmaceutical, food, environmental protection and other industries, higher requirements are placed on the performance of separation equipment. Flat-plate centrifuges came into being. They generate strong centrifugal force through high-speed rotation, and can quickly and efficiently achieve solid-liquid separation or stratification of liquids of different densities.

For example, when separating cell culture fluid in the biopharmaceutical field, the target product may be mixed with residual impurities, affecting product quality and making it difficult to achieve an ideal separation effect. In addition, the skimming device has a complex internal structure, and the residual material after work adheres to the surface of the components, which is difficult to clean thoroughly. Frequent disassembly and cleaning will consume a lot of manpower and material resources. Therefore, it is necessary to propose a flat-plate centrifuge with a skimming device.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Reference Figure 1 - Figure 8As shown: a flat plate centrifuge with a skimming device, including a driving skimming adjustment component 400, a skimming self-cleaning component 200 and a centrifugal adjustment component 600, wherein the driving skimming adjustment component 400 is arranged at the bottom of the centrifugal adjustment component 600, and has a rotating gear 404, the side end of the rotating gear 404 is meshedly connected with a toothed edge 405, and the side end of the toothed edge 405 is provided with an internal lifting column 406.

[0021] The driving skimming adjustment component 400 also includes a variable frequency control motor 401, the output end of the variable frequency control motor 401 is connected to a worm 402 through a transmission, the worm 402 is arranged inside the driving shell, and its front end passes through the driving shell, the side end of the worm 402 is meshedly connected with a worm wheel 403, and the side end of the worm wheel 403 is connected to the center end of the rotating gear 404 through a synchronization rod, and a bottom inner slide groove column 407 is installed inside the driving shell, and an internal lifting column 406 is located inside the bottom inner slide groove column 407 and is slidably connected.

[0022] In this embodiment, the operator first inputs the characteristic parameters of the material to be processed, such as density, viscosity, particle size distribution, etc., into the external logic central controller of the centrifuge control system, and adds the material into the centrifuge tank 601 through the feed end 800, starts the self-driving torque motor 604, and drives the centrifugal drum 603 to start rotating in the centrifuge tank 601. Then, during the centrifugation process, when it is necessary to adjust the height of the centrifugal drum 603, that is, according to the accumulation of the material in the centrifugal drum 603, it is necessary to change the relative position of the centrifugal drum 603 to optimize the skimming effect, or when processing different batches of materials, according to the material characteristics and the preset optimal centrifugal height parameters, the external logic central controller starts the variable frequency control motor 401, and the power output by the variable frequency control motor 401 is transmitted to the worm 402 through the transmission. The rotation of the worm 402 drives the worm wheel 403 meshing therewith to rotate, and the worm wheel 403 drives the synchronous rod to drive The rotating gear 404 rotates, and the rotating gear 404 meshes with the tooth edge 405, thereby pushing the tooth edge 405 to move upward or downward along the bottom inner slide groove column 407. The movement of the tooth edge 405 drives the internal lifting column 406 to slide in the bottom inner slide groove column 407, thereby realizing the lifting and lowering of the bottom center end of the centrifugal drum 603, and adjusting the height of the centrifugal drum 603. The overall device realizes accurate automatic adjustment of the height of the centrifugal drum 603 through the transmission of the frequency conversion control motor 401, the worm 402, and the worm wheel 403 and the cooperation of the rotating gear 404 and the tooth edge 405, so that the height of the centrifugal drum 603 can be accurately adjusted according to the material characteristics and the real-time status during the centrifugal process, and the skimming and centrifugal effects are optimized. When processing materials with obvious stratification of different densities, the height of the centrifugal drum 603 can be accurately controlled, so that the variable aperture skimming port 606 is closer to the target liquid layer, the skimming accuracy is improved, and the mixing of impurities is reduced.

[0023] Embodiment 2: According to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the centrifugal adjustment component 600 has a centrifugal drum 603, a centrifugal tank 601 and a self-driven torque motor 604. The self-driven torque motor 604 is installed inside the centrifugal drum 603 to drive the centrifugal drum 603 to rotate inside the centrifugal tank 601. The bottom center end of the centrifugal drum 603 is connected to the top of the internal lifting column 406. A plurality of adjustment baffles are arranged on the outer circumference of the centrifugal drum 603. The plurality of adjustment baffles are driven by their built-in drive motors to automatically adjust their positions and shapes.

[0024] The centrifugal regulating assembly 600 also includes a variable aperture liquid skimming port 606, which is composed of movable blades and a micro servo motor. The variable aperture liquid skimming port 606 is arranged inside the centrifugal tank 601 near the top position. The two side surfaces of the centrifugal tank 601 are respectively connected with a first discharge end 605 and a second discharge end, and a liquid baffle plate 602 is arranged inside the centrifugal tank 601. The liquid baffle plate 602 is arranged around the outside of the centrifugal drum 603 and leaves a centrifugal operation space. A plurality of pressure sensors and acceleration sensors are arranged inside the centrifugal drum 603. The pressure sensors are evenly distributed on the inner wall of the centrifugal drum 603, and are used to monitor in real time the pressure distribution of the material on the inner wall of the drum during the centrifugal process. The acceleration sensors are used to monitor in real time the pressure distribution of the material on the inner wall of the drum during the centrifugal process. The sensor is installed on the rotating shaft of the centrifugal drum 603, and is used to monitor the acceleration change of the centrifugal drum 603 during the rotation process, and infer the uniformity of material distribution by analyzing the acceleration data. Each adjusting baffle is driven by its built-in driving motor, so that the micro servo motor is used as a power source, and its speed and rotation direction are precisely controlled by an external logic central controller. The output shaft of the driving motor is connected to the lead screw. When the driving motor rotates, it drives the lead screw to rotate. The nut on the lead screw moves linearly under the drive of the lead screw, and the nut is connected to one end of the adjusting baffle through a transmission connecting rod. The linear motion of the nut is converted into the rotation of the adjusting baffle around its mounting axis through the transmission connecting rod, thereby realizing the adjustment of the position and angle of the adjusting baffle.

[0025] A feed end 800 is provided on the surface of the centrifugal tank 601, which is composed of a tank body and a tank cover. A liquid level sensor and a density sensor are respectively installed on the inner wall surface of the liquid baffle 602, and both the liquid level sensor and the density sensor are connected via wireless signals and microprocessor signals in an external logic central controller.

[0026] An automatic skimming structure 300 is installed on the top of the centrifuge tank 601. The automatic skimming structure 300 extends to the interior of the centrifuge tank 601, and the extended part adopts a corrosion-resistant metal pipe as the main connecting component and is connected to the variable aperture skimming port 606. A connecting elbow with automatic angle adjustment is installed at the end of the pipe at the connection between the automatic skimming structure 300 and the variable aperture skimming port 606. The connecting elbow is connected to the pipe body of the automatic skimming structure 300 through a threaded connection, which is convenient for fine-tuning the angle according to the position of the variable aperture skimming port 606. A threaded interface matching the connecting elbow is provided at the entrance of the variable aperture skimming port 606. The connecting elbow is rotated to tighten it with the threaded interface of the variable aperture skimming port 606. The outer wall surface of the centrifuge tank 601 is connected to a pressure relief valve 900, and a drainage output end 700 is provided on the outer surface of the middle position of the centrifuge tank 601.

[0027] In this embodiment, when the above-mentioned material enters the centrifugal tank 601 composed of a tank body and a tank cover through the feed end 800, the self-driven torque motor 604 installed inside the centrifugal drum 603 is started to drive the centrifugal drum 603 to start rotating in the centrifugal tank 601. As the speed gradually increases, the material moves toward the outer wall of the drum under the action of centrifugal force and begins to be distributed. The liquid baffle plate 602 in the centrifugal tank 601 surrounds the outside of the centrifugal drum 603 to build a stable space for centrifugal operation and effectively prevent the material from splashing to other areas of the tank wall. At this stage, the variable frequency control motor 401 in the driving skimming adjustment component 400 is not started, the rotating gear 404, the tooth edge 405 and the internal lifting column 406 remain stationary, and then the multiple pressure sensors inside the centrifugal drum 603 monitor the pressure distribution of the material on the inner wall of the drum in real time, and the acceleration sensor installed on the rotating shaft monitors the acceleration change during the rotation of the centrifugal drum 603. These sensor data are transmitted to the microprocessor in the external logic central controller through wireless signals. The microprocessor performs the calculation based on the preset algorithm. The microprocessor analyzes the material distribution uniformity and accumulation state in the centrifugal drum 603 according to the material characteristic parameters. For example, when the pressure sensor detects that the pressure in a certain area is too high and the acceleration sensor data shows that there is an abnormal fluctuation in the rotation of the drum, the microprocessor determines that the material distribution is uneven. At this time, the microprocessor sends a command to the drive motor built into the adjustment baffle. Since the drive motor of each adjustment baffle uses a micro servo motor as a power source, its speed and rotation direction are precisely controlled by an external logic central controller. The output shaft of the drive motor is connected to the lead screw, so that the drive motor rotates to drive the lead screw to rotate, and the nut on the lead screw performs a linear motion. The nut is connected to one end of the adjustment baffle through a transmission connecting rod, and the linear motion of the nut is converted into the rotation of the adjustment baffle around its mounting axis through the transmission connecting rod, so as to automatically adjust the position and angle of the adjustment baffle. For example, when the material is piled up more at the bottom of the drum, the adjustment baffle can be rotated to a specific angle, such as forming a fan shape, and the adjustment baffle forms a gradual upward trend, guiding the material to move upward, optimizing the material distribution, and improving the centrifugal separation effect. Secondly, the liquid level sensor and density sensor on the inner wall of the liquid baffle 602 in the centrifugal tank 601 are used to monitor the liquid level and density information of the liquid in real time, and transmit the data to the microprocessor in the external logic central controller through wireless signals. When the data received by the microprocessor meets the preset skimming conditions, such as the liquid level reaches a certain height and the liquid density meets the density range of the target separated liquid, the automatic skimming structure 300 is started, and the automatic skimming structure 300 extends to the corrosion-resistant metal pipe inside the centrifugal tank 601 and is connected to the variable aperture skimming port 606. The external logic central controller controls the micro servo motor of the variable aperture skimming port 606 according to the data of the liquid level sensor and the density sensor, adjusts the opening of the movable blades, and makes the aperture of the skimming port adapt to the skimming demand of the current material, so that the liquid enters the automatic skimming port 606 through the variable aperture skimming port 606. The skimming structure 300 then enters the separation control component 500 through the flexible pipe for subsequent processing, or when the automatic skimming structure 300 introduces the liquid that meets the specific liquid level and density conditions, part of the liquid can be directly discharged through the liquid discharge output terminal 700 to meet the situation where there is a need to directly collect the separated liquid. The overall pressure sensor is set inside the centrifugal drum 603 and the acceleration sensor is installed on the shaft to monitor the material distribution state in real time, and the position and angle of the baffle are accurately controlled by the external logic central controller to dynamically optimize the centrifugal environment. When processing unevenly distributed materials, the material can be guided to be more evenly distributed in the drum, reducing the vibration and wear of the equipment caused by the eccentricity of the material, improving the separation accuracy, and can be automatically adjusted according to the real-time changes of the material during the centrifugation process without manual intervention. When continuously producing different batches of materials, the baffle can be quickly adjusted according to the preset parameters and real-time sensor data to improve production efficiency.

[0028] Embodiment 3: According to Figure 1 and Figure 2 As shown, the liquid skimming self-cleaning component 200 includes a support frame 201, and the liquid skimming self-cleaning component 200 is installed on the top outside of the centrifuge tank 601 through the support frame 201, the top side end of the support frame 201 is connected to a ring-joined plate frame 202, the bottom of the support frame 201 is fastened to a movable flat plate base 100, and the side end of the ring-joined plate frame 202 is movably connected to two sets of semi-annular guide rails 203 through a self-locking structure.

[0029] The interiors of the two sets of semi-circular guide rails 203 are connected to the multi-dimensional adjustment arm 204 through a position connection slider. The two sets of semi-circular guide rails 203 are connected to the external logic central controller through wireless signals. The bottom arm surface of the multi-dimensional adjustment arm 204 is provided with a frequency regulator 207, the bottom outer wall surface of the multi-dimensional adjustment arm 204 is provided with a position signal receiver 206, and the bottom of the multi-dimensional adjustment arm 204 is provided with an ultrasonic generator 205.

[0030] In this embodiment, after the centrifuge completes the centrifugal operation and the centrifugal drum 603 stops rotating, the entire device enters the self-cleaning preparation stage, and the external logic central controller sends a start command to start the skimming self-cleaning component 200. At this time, the two sets of semi-annular guide rails 203 form a drive to drive the position connection slider to move in the semi-annular guide rail 203, thereby driving the multi-dimensional adjustment arm 204 to start moving along the trajectory of the semi-annular guide rail 203. The position signal receiver 206 on the outer wall surface of the bottom end of the multi-dimensional adjustment arm 204 receives the position information in real time and feeds the signal back to the external logic central controller. Then, the external logic central controller accurately controls the sliding position of the multi-dimensional adjustment arm 204 in the semi-annular guide rail 203 according to the preset cleaning program and the part information that needs to be cleaned inside the centrifugal tank 601, such as the variable aperture skimming port 606, the automatic skimming structure 300 or the inner wall surface of the centrifugal tank 601. When the multi-dimensional adjustment arm 204 moves to the vicinity of the target cleaning position, the multi-dimensional adjustment arm 204 is adjusted by its own joints. The micro motor further fine-tunes the posture so that the ultrasonic generator 205 at the bottom is accurately aligned with the part to be cleaned. When the ultrasonic generator 205 is aligned with the target cleaning part, the ultrasonic generator 205 is started, and the ultrasonic generator 205 generates high-frequency vibration, and the frequency is generally between 20kHz-100kHz. The high-frequency vibration generated can cause the residual materials attached to the surface of the equipment to resonate and fall off. At the same time, the wave frequency regulator 207 on the surface of the support arm at the bottom end of the multi-dimensional adjustment arm 204 adjusts the frequency and intensity of the ultrasonic wave in real time according to the actual cleaning effect. For example, if there are more residual materials in the cleaning part and the adhesion is stronger, the wave frequency regulator 207 appropriately increases the frequency and intensity of the ultrasonic wave to enhance the cleaning effect. If there are fewer residual materials and they are easy to fall off, the frequency and intensity are reduced to avoid unnecessary damage to the surface of the equipment, or to clean the surfaces such as the frequency conversion control motor 401, the worm 402, the worm wheel 403 and the inner wall of the pipeline in the separation control component 500; After completing the cleaning of one position, the external logic central controller controls the motor movement in the semi-circular guide rail 203 again according to the preset program, so that the multi-dimensional adjustment arm 204 moves to the next position that needs to be cleaned, and repeats the above positioning and cleaning steps to achieve comprehensive cleaning of the complex components inside the centrifuge tank 601. During the entire cleaning process, the movable flat base 100 provides stable support for the support frame 201, ensuring the stability of the skimming self-cleaning component 200 during operation, and preventing the cleaning effect from being affected by vibration or displacement. The overall device can achieve comprehensive cleaning of various complex structures inside the centrifuge, reduce cleaning dead corners, form a real-time adaptive cleaning function, improve cleaning efficiency and cleaning quality, avoid excessive or insufficient cleaning, reduce the frequency of manual contact with the equipment, and reduce the labor intensity and safety risks of operators.

[0032] The side end of the spiral separation and conveying chamber 505 is connected to a coupling 504, and the side end of the coupling 504 is connected to the side end of the worm 402. The bottom of the side end of the spiral separation and conveying chamber 505 is connected to a waste discharge end 506, and the bottom of the other side end of the spiral separation and conveying chamber 505 is connected to a drain pipe 507, and the side end of the drain pipe 507 is connected to a rising liquid pipe 508.

[0033] The top end of the rising liquid pipe 508 is connected to the solenoid valve 512, the side end of the solenoid valve 512 is connected to the detection discharge pipeline 510, the side end of the detection discharge pipeline 510 is connected to the circulation pipeline 511, the bottom end of the circulation pipeline 511 is connected to the top wall surface of the other side end of the spiral separation and conveying chamber 505 through the three-way valve tube, the side end of the three-way valve tube is connected to the solid-liquid separator 509, and the side end of the solid-liquid separator 509 is connected to the detection discharge pipeline 510 through the loop pipe.

[0034] In this embodiment, when the centrifuge completes the centrifugal process, the automatic skimming structure 300 judges that the skimming conditions are met based on the data fed back to the external logic central controller by the liquid level sensor and density sensor in the centrifuge tank 601, and starts, so that the mixed liquid enters the flexible pipe through the automatic skimming structure 300, and then flows into the separation and regulation component 500. At this time, the mixed liquid contains solid and liquid components to be separated. Then, when the mixed liquid enters the separation and regulation component 500, it first reaches the solid phase discharge end 501. Under the continuous action of the centrifugal force and the assistance of the downward gravity, the solid phase material is initially separated from the liquid phase at this position, and falls into the crushing tank 502 connected to the bottom, and the crushing tank is used to discharge the solid phase. 502 crushes the solid phase material into smaller particles for subsequent transportation and further processing, and then the crushed particles are transported to the spiral separation conveying chamber 505 through the powder conveying pipeline 503. The spiral separation conveying chamber 505 is connected to the side end of the worm 402 through the coupling 504. The spiral blades are driven by the power of the rotation of the worm 402. Under the push of the spiral blades, the crushed solid phase particles entering the spiral separation conveying chamber 505 are gradually separated according to their size and density. Under the combined action of centrifugal force and the thrust of the spiral blades, the larger and heavier particles move to the outside of the spiral separation conveying chamber 505 and finally pass through the waste discharge end 50 at the bottom of the side end. 6 is discharged, while smaller and lighter particles move closer to the inside. At the same time, during the separation process, part of the residual liquid and the lighter particle mixture flows to the bottom of the other side end of the spiral separation conveying chamber 505 and is discharged through the discharge pipe 507. The liquid discharged from the discharge pipe 507 enters the rising liquid pipe 508. The solenoid valve 512 at the top of the rising liquid pipe 508 controls the on-off of the liquid according to the command of the external logic central controller. When it is necessary to further detect and process this part of the liquid, the solenoid valve 512 is opened, and the liquid flows into the detection discharge pipeline 510, and the liquid composition and properties are detected in real time. Some of them meet specific conditions (such as specific component content, density range, etc.). ) can pass through the circulation pipeline 511 and return to the top wall surface of the other side end of the spiral separation and conveying chamber 505 through the three-way valve pipe to participate in separation again to improve the separation efficiency and the enrichment degree of specific components. For the liquid that does not meet the circulation conditions, it enters the solid-liquid separator 509. The solid-liquid separator 509 can use a variety of separation or integrated separation technologies such as filtration, sedimentation, centrifugation, etc. to perform deep solid-liquid separation on the liquid. The separated solid phase material is discharged through the bottom valve port of the solid-liquid separator 509, and the liquid phase returns to the detection discharge pipeline 510 through the loop pipe and is discharged, thereby improving the separation accuracy, recovery rate and efficiency of the target components in the mixed liquid.
