Description

Technical Field

[0001] The present invention relates to the field of automation technology, and in particular to a method, device, equipment and storage medium for controlling the inlet pressure of a cyclone group. Background Art

[0002] In the process of mineral processing in metallurgical mines, the slurry in the slurry pump pool is pumped out by the slurry pump and transported to the hydrocyclone group for slurry particle size classification. Due to the size difference between coarse particles and fine particles, they are subject to different centrifugal forces, centripetal buoyancy, fluid drag, etc., and under the effect of centrifugal sedimentation, the slurry with coarse particles is discharged from the sand settling port at the bottom of the hydrocyclone cone, while the slurry with fine particles is discharged from the overflow port at the center of the hydrocyclone cylinder, thereby achieving the purpose of sorting. In the daily production process, the hydrocyclone, as a mechanical equipment, will inevitably have mechanical failures, and the blockage of the hydrocyclone will cause the pressure change of the hydrocyclone, causing the hydrocyclone group to overflow and the sand settling pressure to fluctuate, thus affecting the classification effect of the hydrocyclone group.

[0003] Therefore, in the mineral processing process, stable control of the cyclone group pressure is a key factor in stable production. At present, the cyclone pressure control is usually carried out by manually observing the inlet pressure of the cyclone and manually changing the cyclone valve switch. However, in the actual operation process, there are a large number of valves in each cyclone group, and the valves of each cyclone group are installed at different positions on the inlet main pipe. The influence of each cyclone in each cyclone group on the inlet main pipe pressure is also different, resulting in poor stability of the cyclone group pressure control, low accuracy and complex control process.

[0055] Example 1

[0056] like Figure 1 FIG. 1 is a flow chart of a method for controlling the inlet pressure of a cyclone group provided in an embodiment of the present application. The method for controlling the inlet pressure of a cyclone group provided in an embodiment of the present application comprises the following steps:

[0057] Step S101, setting a target inlet pressure range of the cyclone group.

[0058] Specifically, the target inlet pressure range of the cyclone group is set according to the material properties of the minerals in actual working conditions and the process parameters of the cyclone group combined with the classification effect of each material. The target inlet pressure range is the inlet pressure range that can achieve the preset classification effect when the cyclone group classifies minerals.

[0059] Step S102, obtaining a control model quality code of the cyclone group, and judging whether the cyclone group meets a closed-loop control condition according to the control model quality code.

[0060] Specifically, the control model quality code is a code to ensure the quality of the control model output, and the control model quality code includes a first preset condition and a second preset condition, wherein the first preset condition is True and the second preset condition is False. By judging whether the cyclone group meets the closed-loop control condition according to the control model quality code, it can be ensured that the input data and the operating state of the control model meet the quality standards before the control model participates in the control, thereby improving the stability of the production process.

[0061] The step of obtaining the control model quality code of the cyclone group includes:

[0062] Collect production data within a continuous time period, verify the completeness, accuracy and timeliness of the production data, and generate a control model quality code.

[0063] Determine the model quality code. If the control model quality code is the first preset condition, the model will participate in the control process. If the control model quality code is the second preset condition, the model will not participate in the control, which can avoid control errors caused by data quality problems.

[0064] The step of judging whether the cyclone group meets the closed-loop control condition according to the control model quality code comprises:

[0065] If the control model quality code is the second preset condition, it is determined that the cyclone group does not meet the closed-loop control condition and the step of judging whether the cyclone group can participate in the control according to the control model quality code is repeated.

[0066] It can be understood that by judging the closed-loop control conditions of the cyclone group, it can be ensured that the model is in the best state before participating in the control, reducing fluctuations and instability in the production process. By double checking the data and model quality, it can be ensured that the sorted ore liquid meets the composite sorting standards. When the model control effect is not good, it can be switched back to manual control in time, which improves the flexibility and safety of production.

[0067] Step S103: if the control model quality code is the first preset condition, it is determined that the cyclone group meets the closed-loop control condition and the real-time inlet pressure of the cyclone group is obtained according to a preset period.

[0068] Specifically, the preset period is 1 second, that is, the real-time inlet pressure of the cyclone group is obtained every second, so as to ensure the timeliness of the control model.

[0069] Step S104, controlling the valve of the cyclone group to open or close according to the target inlet pressure range and the real-time inlet pressure.

[0070] Specifically, see Figure 2 , Figure 2 A valve control flow diagram is provided for an embodiment of the present application. The step of controlling the valve of the cyclone group to open or close according to the target inlet pressure interval and the real-time inlet pressure comprises:

[0071] Step S1041, initialize the cumulative number of calculations to 0.

[0072] Step S1042, determining whether the real-time inlet pressure is within the target inlet pressure range.

[0073] Step S1043: if the real-time inlet pressure is within the target inlet pressure range, the accumulated calculation times are reset to 0.

[0074] Step S1044, if the real-time inlet pressure is less than the left extreme value of the target inlet pressure, the cumulative calculation times are increased based on the preset period to determine whether the real-time cumulative calculation times are greater than the preset threshold; if the real-time cumulative calculation times are greater than the preset threshold, the cyclone group valve is closed according to the preset valve control strategy, wherein the preset valve control strategy includes any one of the first valve control strategy, the second valve control strategy, the third valve control strategy and the fourth valve control strategy.

[0075] Step S1045, if the real-time inlet pressure is greater than the right extreme value of the target inlet pressure, the cumulative calculation times are increased based on the preset period to determine whether the real-time cumulative calculation times are greater than the preset threshold; if the real-time cumulative calculation times are greater than the preset threshold, the cyclone group valve is opened according to the preset valve control strategy, wherein the preset valve control strategy includes any one of the first valve control strategy, the second valve control strategy, the third valve control strategy and the fourth valve control strategy.

[0076] In specific implementation, the cumulative calculation times are the times of obtaining the real-time cyclone group inlet pressure, the real-time cumulative calculation times are the times of the cyclone group inlet pressure currently obtained in real time, each time the real-time inlet pressure is within the target inlet pressure range, the cumulative calculation times are initialized, when the real-time inlet pressure is not within the target inlet pressure range, the cumulative calculation times are increased once according to a preset period, when the real-time cumulative calculation times are greater than the preset threshold, it is considered that the cyclone group valve needs to be adjusted, correspondingly, when the real-time cumulative calculation times are less than the preset threshold, it is considered that the cyclone group valve does not need to be adjusted, and the process returns to the step of determining whether the real-time inlet pressure is within the target inlet pressure range, preferably, the preset threshold is 30s, when the real-time inlet pressure is within the target inlet pressure range, the process returns to the previous step. The current working state of the cyclone group can be determined by judging the real-time cumulative calculation times. When the real-time inlet pressure is not within the target inlet pressure range and the real-time cumulative calculation times are greater than the preset threshold, the cyclone group is determined to be in an abnormal state. If the real-time inlet pressure is less than the left extreme value of the target inlet pressure, the valve in the unopened cyclone group is closed to close an opened cyclone. If the real-time inlet pressure is greater than the right extreme value of the target inlet pressure, the valve in the opened cyclone group is opened to open an unopened cyclone. The real-time inlet pressure of the cyclone group is controlled by the control model to ensure that when the inlet pressure exceeds the target inlet pressure range, the inlet pressure is controlled by adjusting the valve of the cyclone group to keep it within the target inlet pressure range, thereby improving the slurry sorting effect. At the same time, by checking the quality code of the control model, the stability and reliability of the control process are ensured, manual intervention is reduced, and production efficiency and safety are improved.

[0077] Preferably, the first valve control strategy includes:

[0078] Sorting and numbering the cyclones according to their positions in the cyclone group;

[0079] Each cyclone is traversed in the order of numbering to control the opening or closing of the valve of the cyclone group.

[0080] It can be understood that the numbers are sorted in the order of physical positions, and the corresponding cyclone valves are opened or closed in combination with the current switch state of the cyclone and the sorting sequence number. When a cyclone needs to be opened, the first cyclone found in the traversal process and in the closed state is opened; when a cyclone needs to be closed, the first cyclone found in the traversal process and in the open state is closed.

[0081] Preferably, the second valve control strategy includes:

[0082] Obtaining an inlet pressure influence factor of each cyclone in the cyclone group;

[0083] Sort and number the cyclones from large to small according to the inlet pressure influencing factors;

[0084] Each cyclone is traversed in the order of numbering to control the opening or closing of the valve of the cyclone group.

[0085] It can be understood that the inlet pressure influence factor is the influence of the relative position of each cyclone in the cyclone group on the inlet pressure. By sorting the cyclones according to the inlet pressure influence factor, the corresponding cyclone valve can be opened or closed according to the sorting sequence number. When a cyclone needs to be opened, the difference between the current pressure and the target pressure is first determined. If the difference is large, the cyclone with a large influence factor is opened first, and if the difference is small, the cyclone with a small influence factor is opened first; when a cyclone needs to be closed, the difference between the current pressure and the target pressure is first determined. If the difference is large, the cyclone with a large influence factor is closed first, and if the difference is small, the cyclone with a small influence factor is closed first.

[0086] Preferably, the third valve control strategy includes:

[0087] Obtaining the cumulative number of times each cyclone in the cyclone group is turned on and off;

[0088] The cyclones are sorted and numbered according to the cumulative number of opening and closing times. The cumulative number of opening times is numbered from small to large, and the cumulative number of closing times is numbered from small to large, forming two number lists;

[0089] Each cyclone is traversed according to the number list to control the opening or closing of the valve of the cyclone group.

[0090] It can be understood that when a cyclone needs to be opened, the first cyclone found in the traversal process that is in the closed state and has the least cumulative opening times is opened; when a cyclone needs to be closed, the first cyclone found in the traversal process that is in the open state and has the least cumulative closing times is closed. The cumulative number of switches is the cumulative number of opening and closing of each cyclone valve. The cyclone valves in the cyclone group are sorted according to the cumulative number of openings and the cumulative number of closings. When the real-time inlet pressure of the cyclone group is greater than the right extreme value of the target inlet pressure, the cyclone valve with the least cumulative opening times is selected according to the sorting sequence number based on the cumulative number of openings. When the real-time inlet pressure of the cyclone group is less than the left extreme value of the target inlet pressure, the cyclone valve with the least cumulative closing times is selected according to the sorting sequence number based on the cumulative number of closings. By controlling the opening or closing of the cyclone valve according to the cumulative number of switches, the full use of the instrument equipment can be guaranteed, and the service life of the instrument equipment is increased.

[0091] Preferably, the fourth valve control strategy includes:

[0092] Obtaining the accumulated working time of each cyclone in the cyclone group;

[0093] Sort and number each cyclone according to the accumulated working time;

[0094] Each cyclone is traversed in the order of numbering, and the opening or closing of the valve of the cyclone group is controlled according to the accumulated working time.

[0095] It can be understood that the cumulative working time of each cyclone is recorded as T [n] =T [n] +t, where t is the time interval from the current opening to the current closing of the current cyclone. The cyclones in the cyclone group are sorted according to the cumulative working time. When the real-time inlet pressure of the cyclone group is greater than the right extreme value of the target inlet pressure, the cyclone valve with a low cumulative working time is preferentially opened according to the sorting sequence number. When the real-time inlet pressure of the cyclone group is less than the left extreme value of the target inlet pressure, the cyclone valve with a high cumulative working time is preferentially closed according to the sorting sequence number. When a cyclone needs to be opened, the first cyclone with the shortest cumulative opening time found in the traversal process in the closed state is opened; when a cyclone needs to be closed, the first cyclone with the longest cumulative opening time found in the traversal process in the open state is closed.

[0096] The embodiment of the present application provides a method for controlling the inlet pressure of a cyclone group, by setting a target inlet pressure range of the cyclone group, obtaining a control model quality code of the cyclone group, judging whether the cyclone group meets a closed-loop control condition according to the control model quality code, and if the control model quality code is a first preset condition, determining that the cyclone group meets the closed-loop control condition and obtaining the real-time inlet pressure of the cyclone group according to a preset period, controlling the valve of the cyclone group to open or close according to the target inlet pressure range and the real-time inlet pressure, and adjusting the valve opening or closing of each cyclone in the cyclone group in real time through the control model, so as to effectively control the real-time inlet pressure of the cyclone group within the target inlet pressure range, thereby improving the stability and accuracy of the pressure control of the cyclone group, and improving the sorting effect and working efficiency of the mineral separation process.
