Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, in particular to a centrifuge and a control system thereof. Background Art

[0002] As a highly efficient solid-liquid separation equipment, centrifuge is widely used in sandblasting media cleaning, mineral separation, chemical production and other fields. By utilizing the centrifugal force generated by high-speed rotation, efficient separation of solid particles and liquid can be achieved, thereby improving the reusability of the medium. However, in actual operation, due to the complexity of feed parameters, cleaning liquid ratio and equipment operation status, the centrifugal separation effect is often affected by multiple factors, making it difficult to achieve a stable and efficient separation effect.

[0003] However, traditional centrifuge control systems mainly rely on manual adjustment of fixed parameters, such as running by setting a fixed centrifugal speed or speed difference. For example, factors such as the particle size distribution in the feed and the proportion of cleaning liquid vary greatly, and fixed operating parameters are difficult to respond to these fluctuations in real time, resulting in unstable separation effects. Current centrifuges lack real-time monitoring and analysis of operating data (such as temperature, vibration, waste liquid discharge, etc.), making it difficult to automatically determine whether the centrifugal separation effect is qualified. The lack of a feedback adjustment mechanism makes the operating procedures cumbersome and dependent on personnel experience.

[0004] Therefore, it is necessary to design a centrifuge and a control system thereof to solve the problems existing in the current technology. Summary of the invention

The judgment unit selects the larger one of the first duration and the second duration as the duration for turning on the high-pressure gas.

[0033] Further, when the judgment unit determines that the centrifugal effect is unqualified, the processing unit determines the real-time characteristic factor according to the temperature data, the vibration data and the feed data, including:

[0036] Further, when the judgment unit determines that the centrifugal effect is unqualified, the processing unit compares the real-time characteristic factor with the historical adjustment data, and determines the adjustment coefficient according to the comparison result to adjust the internal centrifugal speed, including:

DETAILED DESCRIPTION

[0062] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0063] In some embodiments of the present application, see Figure 1 As shown, a centrifuge control system includes: a collection unit, a judgment unit, a processing unit, a correction unit and a storage unit.

[0064] The collecting unit is configured to collect feed data and determine the internal centrifugal speed and the difference between the internal and external centrifugal speeds according to the feed data. The feed data includes the maximum particle size difference and the cleaning liquid ratio.

[0065] The judgment unit is configured to collect solid discharge data within a preset time, and judge whether the centrifugal effect of the shot blasting medium is qualified according to the solid discharge data. When the centrifugal effect is judged to be unqualified, the judgment unit is further configured to collect waste liquid discharge data, collect the surface pressure of the centrifuge spiral blades, analyze the waste liquid discharge data and the surface pressure, and judge whether to open the high-pressure gas to loosen the material inside the centrifuge.

[0066] The processing unit is configured to collect temperature data and vibration data in the centrifuge when the judgment unit determines that the centrifugation is unqualified, determine the real-time characteristic factor according to the temperature data, vibration data and feed data, compare the real-time characteristic factor with the historical adjustment data, and determine the adjustment coefficient according to the comparison result to adjust the internal centrifugal speed.

[0067] The correction unit is configured to collect second solid discharge data of the centrifuge running at the adjusted internal centrifuge speed, and determine whether to correct the adjustment coefficient according to the second solid discharge data.

[0068] The storage unit is configured to store the real-time characteristic factor and the adjustment coefficient.

[0069] Specifically, the acquisition unit is responsible for real-time monitoring of feed data, including the maximum particle size difference and the ratio of cleaning liquid. Based on these data, the internal centrifugal speed and the internal and external centrifugal speed difference are calculated to ensure that the separation efficiency of the centrifuge under different feed conditions is optimal. By dynamically adjusting the centrifugal speed and speed difference, the adaptability of the equipment to complex feed conditions is improved. The judgment unit collects solid discharge data within a preset time, analyzes its discharge volume and moisture content, and determines whether the centrifugal effect is qualified. If the centrifugal effect is found to be unqualified, the waste liquid discharge data and the surface pressure of the spiral blade are further collected, and through comprehensive analysis, it is determined whether there are abnormal conditions such as blockage. When the abnormality is confirmed, the judgment unit triggers the high-pressure gas system to loosen the internal material and restore the normal operation of the centrifuge. When the judgment unit detects that the centrifugal effect is unqualified, regardless of whether blockage occurs. The processing unit collects the internal temperature and vibration data of the centrifuge, and calculates the real-time characteristic factor in combination with the feed data. The real-time characteristic factor reflects the current operating status of the centrifuge. By comparing with the historical adjustment data, the adjustment coefficient is determined, and the internal centrifugal speed is dynamically adjusted to optimize the equipment operating parameters and improve the separation efficiency. The correction unit is responsible for verifying the operating results adjusted by the processing unit. By collecting the second solid discharge data corresponding to the adjusted internal centrifugal speed, it is analyzed whether the adjustment coefficient needs to be further corrected to ensure the accuracy and stability of the system adjustment. The storage unit is used to store real-time characteristic factors and adjustment coefficients to form a historical data set of operation. If the correction unit adjusts the adjustment coefficient, the corrected adjustment coefficient is stored. If the adjustment coefficient is not corrected, the adjustment coefficient is directly stored. These data not only support real-time adjustment, but also provide optimization basis for long-term operation, improving the intelligent level of equipment operation.

[0070] It is understandable that through the collaborative work of the acquisition unit, judgment unit, processing unit, correction unit and storage unit, the real-time monitoring, intelligent judgment, dynamic adjustment and precise correction of the centrifuge operating status are realized. Compared with the traditional centrifuge control system, the adaptability of the centrifuge to the fluctuation of feed conditions (such as particle size difference and cleaning liquid ratio) is improved to ensure the stability of the separation effect. By collecting waste liquid discharge data and spiral blade surface pressure in real time, it can quickly detect and respond to abnormal conditions such as blockage and reduce equipment downtime. Real-time characteristic factors are calculated using multidimensional data such as temperature and vibration, and the adjustment coefficient is optimized after comparison with historical data to achieve dynamic adaptation for efficient operation. The correction unit provides a closed-loop verification mechanism to further improve the accuracy and reliability of the adjustment results. The storage unit forms a complete operation data chain, providing data support for long-term optimization and predictive maintenance.

[0071] In some embodiments of the present application, when the acquisition unit determines the internal centrifugal speed and the internal and external centrifugal speed difference according to the feed data, it includes:

[0072]

[0073]

[0074] Where V represents the centrifugal speed, k1 represents the speed gain coefficient, and its value range is [50, 100]. represents the density of solid medium, represents the density of the cleaning liquid, d represents the maximum particle size difference, H represents the cleaning liquid ratio, k2 represents the cleaning liquid ratio smoothing coefficient, the value range is [1, 5], k3 represents the constant term, the value range is [5, 20], ΔV represents the difference in centrifugal speed inside and outside, Indicates the viscosity of the cleaning fluid.

[0075] It is understandable that the density of the solid medium, the density and viscosity of the cleaning liquid, the maximum particle size difference and the proportion of the cleaning liquid are comprehensively considered to ensure the stable operation of the centrifuge under variable feed conditions. Through the flexible adjustment of the speed gain coefficient, the smoothing coefficient and the constant term, the operating parameters are optimized and the solid-liquid separation efficiency is improved. By calculating the difference in the centrifugal speed between the inside and outside, the energy consumption caused by the excessive speed difference is reduced, while ensuring that the separation effect is not affected. Based on the adjustment mechanism of multi-dimensional parameters, the problem of unstable centrifugal effect caused by feed fluctuations during operation is effectively reduced.

[0076] In some embodiments of the present application, when the judgment unit judges whether the centrifugal effect of the shot blasting medium is qualified according to the solid discharge data, it includes: the solid discharge data includes the proportion of cleaning liquid in the solid discharge. The judgment unit compares the proportion of cleaning liquid in the solid discharge with the maximum allowable proportion of cleaning liquid, and judges whether the centrifugal effect of the shot blasting medium is qualified according to the comparison result.

[0077] Specifically, when the proportion of cleaning liquid in the solid discharge is greater than the maximum allowable proportion of cleaning liquid, the judgment unit determines that the centrifugal effect is unqualified. When the proportion of cleaning liquid in the solid discharge is less than or equal to the maximum allowable proportion of cleaning liquid, the judgment unit determines that the centrifugal effect is qualified.

[0078] It is understandable that the proportion of cleaning liquid in the solid discharge is used as the evaluation basis to intuitively reflect whether the separation effect of the centrifugal process meets the process requirements. Through real-time data acquisition and calculation, unqualified states can be quickly identified and a reliable decision-making basis can be provided for subsequent processing units. By clarifying the criteria for qualified and unqualified judgments, energy waste due to excessive centrifugation can be avoided, and the process time for subsequent repeated processing can be reduced. The maximum allowable proportion of cleaning liquid can be adjusted according to different process requirements, adapting to a variety of shot blasting media and cleaning liquid ratios, and enhancing the versatility of the system.

[0079] In some embodiments of the present application, the judgment unit collects the surface pressure of the spiral blades of the centrifuge, and when analyzing the surface pressure, it includes: the judgment unit divides the surface pressure into multiple sub-surface pressure data sets based on each circle of the spiral blades, and if there is data with zero pressure in the sub-surface pressure data set, the corresponding sub-surface pressure data set is eliminated, the remaining sub-surface pressure data sets after the elimination are analyzed, and whether the pressure is uniform is determined based on the analysis results.

[0080] The judgment unit arranges the pressure data in each sub-surface pressure data set into a two-dimensional pressure matrix according to the sensor position.

[0081] Arbitrarily determine a center point in the two-dimensional pressure matrix.

[0082] Take the center point as the center of the circle and determine the neighborhood range.

[0083] Calculate the average pressure based on the pressure data of each coordinate point within the neighborhood.

[0084] When the difference between the pressure data at the center point and the average pressure is greater than the pressure difference threshold, it is determined that the pressure data at the center point is non-uniform data.

[0085] When non-uniform data exists in all sub-surface pressure data sets, the judgment unit determines that the pressure is non-uniform.

[0086] In some embodiments of the present application, when the judgment unit determines the waste liquid discharge data, it includes: the judgment unit obtains the waste liquid expected data according to the feed data and the solid discharge data, and compares the waste liquid discharge data with the waste liquid expected data. When the waste liquid discharge data is less than the waste liquid expected data, the judgment unit determines that the centrifuge is blocked by material inside.

[0087] When the judgment unit determines that the material inside the centrifuge is blocked or the pressure is uneven, the high-pressure gas is turned on to loosen the material inside the centrifuge, and the waste liquid difference is obtained according to the waste liquid discharge data and the waste liquid expected data. The waste liquid difference is the difference between the waste liquid expected data and the waste liquid discharge data. The judgment unit determines the first duration of turning on the high-pressure gas according to the waste liquid difference, and the first duration is proportional to the waste liquid difference. The judgment unit determines the second duration of turning on the high-pressure gas according to the number of pressure uneven points, and the second duration is proportional to the number of pressure uneven points. The judgment unit selects the larger of the first duration and the second duration as the duration of turning on the high-pressure gas.

[0088] It can be understood that the judgment unit divides the surface pressure into multiple sub-surface pressure data sets based on each spiral blade. If there is data with zero pressure in the sub-surface pressure data set (such as an area without material on the blade), the data set is removed to ensure the accuracy of the analysis. Each sub-surface pressure data is arranged into a two-dimensional matrix according to the sensor position to represent the pressure distribution. A center point is arbitrarily selected in the matrix, a neighborhood range (which can be a rectangular or circular range) is defined, and the average value of the pressure data of each coordinate point in the neighborhood is calculated. If the difference between the center point pressure data and the neighborhood average pressure exceeds the set pressure difference threshold, the point is determined to be non-uniform data. Check all sub-surface pressure data sets. If there is non-uniform data in each data set, it is determined that the overall pressure is uneven and the cleaning operation needs to be started. The expected data of the waste liquid is calculated based on the feed data (feed flow rate, cleaning liquid ratio) and the solid discharge data (solid ratio, humidity) as a judgment basis. The actual waste liquid discharge data can be collected by the sensor in real time. If the actual waste liquid discharge data is lower than the expected data, it is determined that the waste liquid flow hole inside the centrifuge may be blocked. Combine the pressure distribution and waste liquid discharge to double confirm whether the centrifuge is running abnormally to avoid misjudgment or missed judgment. Dynamically adjust the high-pressure gas duration according to the waste liquid difference and the number of pressure uneven points to improve cleaning efficiency and avoid energy waste caused by excessive cleaning. Clear internal blockages or accumulation in time to ensure that the centrifuge operates in an efficient and stable state and reduce equipment failure rate.

[0089] In some embodiments of the present application, when the judgment unit determines that the centrifugal effect is unqualified, the processing unit determines the real-time characteristic factor according to the temperature data, the vibration data and the feed data, including:

[0090]

[0091] Among them, F represents the real-time characteristic factor, T represents the temperature data, Z represents the vibration data, and Tmax represents the maximum temperature allowed by the equipment. represents the density of the cleaning fluid, d represents the maximum particle size difference, represents the viscosity of the cleaning liquid, H represents the proportion of the cleaning liquid, α represents the temperature weight coefficient, and its value range is [1, 5], β represents the vibration weight coefficient, and its value range is [10, 50], and γ represents the feed quality weight coefficient, and its value range is [0.5, 2].

[0092] It is understandable that the integration of temperature, vibration and material characteristics, and comprehensive consideration of various factors affecting equipment operation, improves the judgment accuracy. Real-time calculation and adjustment of operating parameters ensure that the equipment can quickly adapt to changes in feed parameters and operating status, improve operating stability and separation efficiency, and reduce unnecessary manual intervention. Through dynamic adjustment based on real-time characteristic factors, the potential damage to the equipment caused by high temperature or abnormal vibration is effectively reduced, and the equipment life is extended.

[0093] In some embodiments of the present application, when the judgment unit determines that the centrifugal effect is unqualified, the processing unit compares the real-time characteristic factor with the historical adjustment data, and determines the adjustment coefficient to adjust the internal centrifugal speed according to the comparison result, including: when there is similar data of the real-time characteristic factor in the historical adjustment data, the processing unit obtains the historical adjustment mean coefficient according to the historical adjustment coefficient in the similar data, and the processing unit uses the historical adjustment mean coefficient as the adjustment coefficient. When there is no data in the historical adjustment data in which the difference between the historical characteristic factor and the real-time characteristic factor is less than a% of the real-time characteristic factor, the processing unit determines the adjustment coefficient to adjust the internal centrifugal speed according to the temperature data and the vibration data. The similar data is the data in which the difference between the historical characteristic factor and the real-time characteristic factor is less than a% of the real-time characteristic factor.

[0094] In some embodiments of the present application, when the processing unit determines the adjustment coefficient according to the temperature data and the vibration data to adjust the internal centrifugal speed, it includes:

[0095]

[0096] Among them, E represents the adjustment coefficient, T represents the temperature data, T0 represents the temperature reference value, Z represents the vibration data, Tmax represents the maximum allowable temperature of the equipment, and Tw represents the ideal working temperature of the equipment. Represents the vibration nonlinear correction coefficient, with a value range of [0.5, 1.5].

[0097] Specifically, the adjustment coefficient adjusts the speed of the inner centrifuge, that is, the product of the adjustment coefficient and the inner centrifuge speed is used as the adjusted inner centrifuge speed.

[0098] It is understandable that the centrifugal state is evaluated in real time in combination with the equipment operating status and feed characteristics, providing an accurate basis for adjustment. The weight coefficient is introduced to optimize the sensitivity and applicability of the characteristic factor according to the equipment requirements and adapt to various working conditions. The calculation process takes into account the multiple effects of temperature, vibration and feed, so that the real-time characteristic factor can accurately reflect the problems in the centrifugal process. By quantifying the effects of temperature and vibration, the equipment is prevented from being damaged due to overload or unstable operation, and the service life of the equipment is extended.

[0099] In some embodiments of the present application, when the correction unit determines whether to correct the adjustment coefficient based on the second solid discharge data, it includes: the correction unit obtains the proportion of cleaning liquid in the second solid discharge data according to the second solid discharge data, when the proportion of cleaning liquid in the second solid treatment is greater than the maximum allowable proportion of cleaning liquid, the correction unit determines the cleaning liquid proportion difference according to the cleaning liquid proportion in the second solid treatment and the maximum allowable proportion of cleaning liquid, compares the cleaning liquid proportion difference with the first preset proportion difference and the second preset proportion difference respectively, and determines the correction coefficient according to the comparison result to correct the adjustment coefficient. The first preset proportion difference is less than the second preset proportion difference. When the proportion of cleaning liquid in the second solid treatment is less than or equal to the maximum allowable proportion of cleaning liquid, the correction unit determines not to correct the adjustment coefficient.

[0100] Specifically, when the proportional difference is less than or equal to the first preset proportional difference, the correction unit determines the first correction coefficient to correct the adjustment coefficient. When the proportional difference is greater than the first preset proportional difference and less than or equal to the second preset proportional difference, the correction unit determines the second correction coefficient to correct the adjustment coefficient. When the proportional difference is greater than the second preset proportional difference, the correction unit determines the third correction coefficient to correct the adjustment coefficient. The first correction coefficient is less than the second correction coefficient, and the second correction coefficient is less than the third correction coefficient.

[0101] It is understandable that through the hierarchical management of the ratio difference, different correction coefficients are used to avoid excessive or insufficient adjustments and improve the stability of centrifugal separation. Real-time analysis of the second solid discharge data and timely correction of problems arising during the centrifugation process improve the adaptability of the system. When the cleaning liquid ratio meets the requirements, unnecessary corrections are avoided to reduce the consumption of system operating resources. Multiple correction coefficients are designed to finely handle different degrees of separation anomalies, improving the accuracy and efficiency of regulation.

[0102] In the above embodiment, the acquisition unit dynamically monitors the feed data (such as the maximum particle size difference and the ratio of the cleaning liquid), and adjusts the internal centrifugal speed and speed difference in real time according to these data to ensure the adaptability of the equipment to diversified feed conditions. The judgment unit quickly evaluates the centrifugal effect by analyzing the solid discharge data and the waste liquid discharge data, and promptly starts the high-pressure gas to loosen the material in combination with the spiral blade pressure detection to avoid equipment blockage. The processing unit calculates the real-time characteristic factors based on temperature, vibration and historical adjustment data to accurately optimize the adjustment coefficient, thereby dynamically adjusting the operating parameters to improve the separation efficiency. The correction unit realizes closed-loop optimization of the adjustment parameters through secondary data verification. The storage unit records and analyzes historical data, builds an intelligent adjustment model, and provides data support for subsequent operations. The stability, separation effect and adaptability of the centrifuge are improved, and the need for manual intervention and maintenance costs are reduced.

The first centrifugal assembly 110 includes a sleeve rotating shaft 111, a first centrifugal housing 112 and a first centrifugal base 113. The inner wall of the first centrifugal housing 112 is provided with a buffer layer. And waste liquid circulation ports 1121 are evenly arranged on the left side of the first centrifugal housing 112, and solid discharge ports 1122 are evenly arranged on the right side. The second centrifugal assembly 120 includes a centrifugal main shaft 121, a second centrifugal bucket 122 and a second centrifugal tail shaft 123. A feed port 1221 is provided at the center of the second centrifugal bucket 122 and the second centrifugal tail shaft 123, and the feed port 1221 is used for materials to enter the second centrifugal bucket 122. The second centrifugal bucket 122 is also provided with an inner discharge port 1222, and the inner discharge port 1222 is used to convey materials from the inside of the centrifugal bucket to between the second centrifugal bucket 122 and the first centrifugal housing 112 under the action of centrifugal force. The outer surface of the centrifugal bucket is also provided with a spiral blade 1223. Among them, the sleeve rotating shaft 111 in the first centrifugal assembly 110 is fixedly connected to the first centrifugal shell 112, and the first centrifugal shell 112 is fixedly connected to the first centrifugal base 113. The centrifugal main shaft 121 in the second centrifugal assembly 120 is fixed to the left side of the second centrifugal bucket 122, and the second centrifugal tail shaft 123 is fixed to the right side of the second centrifugal bucket 122. The sleeve rotating shaft 111 is sleeved on the centrifugal main shaft 121, and the sleeve rotating shaft 111 and the centrifugal main shaft 121 are connected through bearings and seals, and the first centrifugal base 113 and the second centrifugal tail shaft 123 are connected through contact seal bearings 130. The sleeve rotating shaft 111 and the second centrifugal tail shaft 123 are connected to the support frame 200 through bearings, and the support frame 200 provides support for the device.

[0110] It is understandable that the housing 300 is buckled outside the first centrifugal assembly 110 to prevent waste liquid from splashing, and the inner wall of the housing 300 is provided with a vibration sensor and a temperature sensor, and the vibration sensor and the temperature sensor transmit data through a wireless network.

The control module 600 uses the functions of each unit in the above-mentioned centrifuge control system when controlling the drive module and the electromagnetic valve.

[0111] It can be understood that the operation process of the centrifuge is:

[0112] The control module 600 integrates the functions of the above-mentioned centrifuge control system, determines the internal centrifugal speed and the internal and external centrifugal speed difference by collecting the feeding data of the feeding funnel 410, and the second driver 520 is started to drive the centrifugal main shaft 121 to rotate counterclockwise, so that the second centrifugal assembly 120 rotates at the determined internal centrifugal speed. The second centrifugal assembly 120 is arranged inside the first centrifugal assembly 110 and rotates coaxially with it. The control module 600 starts the first driver 510, drives the sleeve rotating shaft 111 to rotate through the belt, so that the first centrifugal assembly 110 rotates, and determines the rotation speed of the first centrifugal assembly 110 by the determined internal and external centrifugal speed difference. The control module 600 starts the third driver 530 to drive the feeding screw 420 to rotate clockwise. The material enters the second centrifugal bucket 122 in the second centrifugal assembly 120 through the feeding port 1221 set on the second centrifugal assembly 120. The conical structure of the feeding screw 420 ensures that the material enters the second centrifugal bucket 122 evenly and smoothly, effectively avoiding the transportation problem caused by particle blockage. After the material enters the second centrifugal bin 122, it flows out through the internal discharge port 1222 on the second centrifugal component 120 under the action of centrifugal force. Under the action of the first centrifugal component 110 and the second centrifugal component 120, the solid shot blasting medium is preferentially deposited on the spiral blade 1223, and moves to the right under the action of the spiral blade 1223 until it reaches the right side of the first centrifugal housing 112, and is discharged through the solid discharge port 1122, and is finally collected through the medium collection port 210 set on the support frame 200.
