Description

Technical Field

[0001] The present application belongs to the field of mineral processing technology, and specifically relates to a time-sharing control method and control system for remote control and automatic iron removal, which is suitable for iron removal operations in the iron removal link of high-pressure roller feeding. Background Art

[0002] In the high-pressure roller wet pre-selection process, if the material processed by the high-pressure roller contains objects such as iron parts, the roller surface of the high-pressure roller will be damaged, seriously affecting the service life of the high-pressure roller. At the same time, the rolling effect of the high-pressure roller will also decrease, making it difficult to improve the production efficiency of the selection plant.

[0003] In the common high-pressure roller wet pre-selection process, the high-pressure roller feed belt is equipped with a disc iron remover through the guide rail and the walking device to remove the iron pieces in the feed belt material. The manual iron removal process is as follows: the disc iron remover is excited to absorb the iron pieces above the feed belt. When the operator finds that the disc iron remover is almost full of iron pieces, the disc iron remover is operated to move to the iron release position outside the feed belt, and the disc iron remover is controlled to demagnetize and remove the iron pieces, and then the iron remover is operated to return to the top of the feed belt, and the iron remover is excited to absorb iron, and the next cycle begins. The disadvantages of manual iron removal with a disc-type iron remover are: (1) When manually moving the disc-type iron remover for iron removal, the condition of the iron adsorbed by the iron remover is random, the iron removal effect cannot be guaranteed, and a dedicated operator is required on site. With the development of smart manufacturing and the reduction of on-site operators, it is difficult to fully automate the iron removal process; (2) The iron removal process is not included in the plant automation system, which makes it difficult to remotely operate the iron remover and abnormal iron parts cannot be handled in time; (3) The moving part of the iron remover uses infrared limiters, but the dust accumulated on the production site will affect the use of the infrared limiter and easily cause production accidents. Summary of the invention

[0004] The present application provides a time-sharing control method and control system for remote control and automatic iron removal, which improves the current production status of manual operation of the iron remover and effectively improves work efficiency and safety.

[0005] The technical solution to solve the technical problem in this application is as follows:

[0006] According to one aspect of the present application, a time-sharing control method for remote control and automatic iron removal is provided, which is used to control a disc iron remover above a high-pressure roller feeding belt to absorb and release iron through a PLC automation system, a guide rail is arranged above the high-pressure roller feeding belt, the disc iron remover is arranged on the guide rail through a walking mechanism, and infrared limit devices are respectively arranged at the iron absorption and release positions of the disc iron remover, and the iron absorption walking signal, iron release walking signal, iron release and magnetization signal, iron absorption excitation signal of the disc iron remover and the infrared limit signal of the infrared limit device are incorporated into the PLC automation system and controlled, and the method steps are as follows:

[0007] S1, the disc iron remover is initially located at the iron-absorbing position above the high-pressure roller feeding belt and is in the iron-absorbing excitation state;

[0008] S2. Timing or remote operation of the disc iron remover by the operator makes the disc iron remover enter the iron release walking state through the walking mechanism. The walking distance is determined by the position spacing of the infrared limit devices at the iron suction and release positions and the walking time. The walking time accuracy is in seconds.

[0009] S3. After the disc iron remover reaches the iron release position, it is controlled to enter the iron release and demagnetization state. The demagnetization time should take into account both the time for the disc iron remover to stabilize and stop, and the time for the adsorbed iron to be released;

[0010] S4. After the iron release process is completed, the disc-type iron remover is controlled to enter the iron absorption walking state. The walking distance is determined by the position spacing of the infrared limit devices at the iron absorption and release positions and the walking time. The walking time accuracy is in seconds.

[0011] S5, the disc iron remover reaches above the high-pressure roller feeding belt, controls it to enter the iron absorption excitation state, and returns to S1 for loop execution.

[0012] Furthermore, the travel time of the disc-type iron remover in the iron releasing walking state or the iron attracting walking state is determined by the travel speed of the disc-type iron remover; the demagnetization time is determined based on the actual demagnetization and iron releasing time of the disc-type iron remover on site.

[0013] Further, ctq_man_ctrl is set as the manual remote operation signal, s_clock_hour, s_clock_minute, s_clock_second are the hour, minute, and second values ​​of the PLC automation system, p11_yc and p11_yx are the remote and operation signals of the high-pressure roller feeding belt, ctq_lc is the excitation enable signal of the iron remover, ctq_ft_xw and ctq_xt_xw are the infrared iron release operation limit and iron absorption operation limit signals of the iron remover, and ctq_ft_yx and ctq_xt_yx are the iron release and iron absorption operation enable signals of the iron remover, respectively;

[0015] When the manual remote control of the iron remover is implemented, the steps are as follows:

[0016] S1, manual remote operation sends out the iron remover working signal ctq_man_ctrl. If the operation is completed after the set time and complies with the time-sharing rules, the remote control iron suction and discharge process timer T5 is enabled;

[0017] S2. After the iron remover working signal ctq_man_ctrl pulse is sent, the iron release walking timer T4 is enabled according to the set time, and the iron release operation signal ctq_ft_yx is enabled at the same time. At this time, the iron remover walks on the guide rail to the iron release position until the iron release infrared limit ctq_ft_xw sends a signal or the set walking operation time ends;

[0018] S3, after the iron remover reaches the iron release position, it sends out a pulse, and enables the iron release timer T6 according to the set time, thereby driving the iron remover to release iron ctq_lc, and the set time includes the iron remover movement stabilization time and iron release time;

[0019] S4, after the iron remover has finished releasing the iron, it sends out a pulse, enables the iron absorption timer T7 according to the set time, and enables the iron absorption operation signal ctq_xt_yx at the same time. At this time, the iron remover moves on the guide rail to the iron absorption position until the iron absorption infrared limit ctq_xt_xw sends out a signal or the set operation time ends;

[0020] S5, after the iron remover reaches the iron absorption position, when the T1 and T5 process timers are reset, the iron remover excitation signal ctq_lc is enabled, and the iron remover begins to enter the iron absorption state, waiting for the timing automatic iron remover signal or the manual remote control signal ctq_man_ctrl, and enters the next iron absorption and release operation cycle;

[0021] When the iron remover is automatically remotely controlled at a scheduled time, the iron remover is automatically operated strictly in chronological order and is interlocked with the p11_yc and p11_yx signals in the production system. The operation implementation process is as follows:

[0022] S1, send out pulses at set intervals, enable iron release travel timer T0 according to the set time, and enable iron release operation signal ctq_ft_yx at the same time. At this time, the iron remover moves on the guide rail to the iron release position until the iron release infrared limit ctq_ft_xw sends out a signal or the set operation time ends;

[0023] S2, walking timer T0 pulse, enables the remote control iron absorption and release process timer T1 according to the set time. In the iron absorption and release process of the iron remover, the process timer must be enabled to perform related actions;

[0024] S3, after the iron remover reaches the iron release position, it sends out a pulse, and enables the iron release timer T2 according to the set time, thereby driving the iron remover to release iron ctq_lc.

[0027] The time-sharing rule for remote control operation and automatic operation is that remote control operation is possible after 4 minutes of each hour, and automatic iron removal operation is performed before 4 minutes.

[0028] Furthermore, when the iron remover is automatically remotely controlled at a fixed time, the interval time is set to 1 minute every 3 hours in step S1.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present disclosure belongs. What is not described in detail in this application is the known technology of technicians in this technical field.

[0034] Example 1

[0035] like Figure 1-2 As shown, the present application provides a time-sharing control method for remote control and automatic iron removal, which is used to control the disc iron remover above the high-pressure roller feeding belt to absorb and release iron through a PLC automation system. A guide rail is arranged above the high-pressure roller feeding belt, and the disc iron remover is arranged on the guide rail through a walking mechanism. The iron absorption and iron release positions of the disc iron remover are respectively provided with infrared limit devices. The iron absorption walking signal, iron release walking signal, iron release and magnetization signal, iron absorption excitation signal of the disc iron remover and the infrared limit signal of the infrared limit device are incorporated into the PLC automation system and controlled. The steps of the iron removal method are as follows:

[0036] S1, the disc iron remover is initially located at the iron-absorbing position above the high-pressure roller feeding belt and is in the iron-absorbing excitation state;

[0037] S2. Timing or remote operation of the disc iron remover by the operator makes the disc iron remover enter the iron release walking state through the walking mechanism. The walking distance is determined by the position spacing of the infrared limit devices at the iron suction and release positions and the walking time. The walking time accuracy is in seconds.

[0038] S3. After the disc iron remover reaches the iron release position, it is controlled to enter the iron release and demagnetization state. The demagnetization time should take into account both the time for the disc iron remover to stabilize and stop, and the time for the adsorbed iron to be released;

[0039] S4. After the iron release process is completed, the disc-type iron remover is controlled to enter the iron absorption walking state. The walking distance is determined by the position spacing of the infrared limit devices at the iron absorption and release positions and the walking time. The walking time accuracy is in seconds.

[0040] S5, the disc iron remover reaches above the high-pressure roller feeding belt, controls it to enter the iron absorption excitation state, and returns to S1 for loop execution.

[0041] In the present embodiment, the walking time of the disc iron remover in the iron releasing walking state or the iron attracting walking state is determined by the walking speed of the disc iron remover, thereby realizing the dual protection of infrared limit and walking time limit when the disc iron remover is walking, avoiding production accidents caused by relying solely on infrared limit; in the present embodiment, the demagnetization time is determined according to the actual demagnetization and iron releasing time of the disc iron remover on site.

[0042] Specifically, set ctq_man_ctrl as the manual remote operation signal, s_clock_hour, s_clock_minute, and s_clock_second as the hour, minute, and second values ​​of the PLC automation system, p11_yc and p11_yx are the remote and operation signals of the high-pressure roller feeding belt, respectively, ctq_lc is the excitation enable signal of the iron remover, ctq_ft_xw and ctq_xt_xw are the infrared iron release operation limit and iron absorption operation limit signals of the iron remover, and ctq_ft_yx and ctq_xt_yx are the iron release and iron absorption operation enable signals of the iron remover, respectively.

[0043] When the PLC automation system is controlled, various times are set through multiple extended pulse timers, among which: T0, T1, T2 and T3 are set as the iron release walking timer, remote control iron absorption and release process timer, iron release timer and iron absorption timer, respectively, and are used for timed automatic iron removal; T4, T5, T6 and T7 are set as the iron release walking timer, remote control iron absorption and release process timer, iron release timer and iron absorption timer, respectively, and are used for manual remote control iron removal. The duration of each timer is determined according to actual production. This embodiment is a field measurement timer duration.

[0044] When the manual remote control of the iron remover is implemented, the steps are as follows:

[0045] S1. Manual remote operation sends out the iron remover working signal ctq_man_ctrl. If the operation is carried out after 4 minutes of each hour and complies with the time-sharing rules, the 2-minute remote control iron suction and discharge process timer T5 is enabled; among which, the time-sharing rules for remote control operation and automatic operation are that remote control operation is allowed after 4 minutes of each hour, and automatic iron removal operation is performed before 4 minutes; in the iron suction and discharge process of the disc iron remover, the process timer must be enabled before relevant actions can be performed.

[0046] S2. After the iron remover working signal ctq_man_ctrl pulse is sent out, the 6-second iron release walking timer T4 is enabled, and the iron release operation signal ctq_ft_yx is enabled at the same time. At this time, the iron remover moves on the guide rail to the iron release position until the iron release infrared limit ctq_ft_xw sends a signal or the 6-second walking operation time ends.

[0047] S3, after the iron remover reaches the iron release position, it sends out a pulse, enabling the 1-minute iron release timer T6, thereby driving the iron remover to release iron ctq_lc. The 1 minute includes the iron remover movement stabilization time and iron release time.

[0048] S4, after the iron remover has finished releasing the iron, it sends out a pulse, enabling the 6-second iron absorption timer T7, and at the same time enabling the iron absorption operation signal ctq_xt_yx. At this time, the iron remover moves on the guide rail to the iron absorption position until the iron absorption infrared limit ctq_xt_xw sends out a signal or the 6-second operation time ends;

[0049] S5, after the iron remover reaches the iron absorption position, when the T1 and T5 process timers are reset, the iron remover excitation signal ctq_lc is enabled, and the iron remover begins to enter the iron absorption state, waiting for the timing automatic iron remover signal or the manual remote control signal ctq_man_ctrl, and enters the next iron absorption and release operation cycle;

[0050] When the iron remover is automatically remotely controlled at a fixed time, the iron remover is automatically operated in strict accordance with the time sequence. At the same time, it must be interlocked with the p11_yc and p11_yx signals in the production system. p11_yc and p11_yx are remote and operating signals during the production of the high-pressure roller feeding belt. The automatic iron removal system can operate normally during production through interlocking. The operation implementation process is as follows:

[0051] S1, sends out a pulse every 1 minute of every 3 hours, enabling the 6-second iron release travel timer T0, and enabling the iron release operation signal ctq_ft_yx at the same time. At this time, the iron remover moves on the guide rail to the iron release position until the iron release infrared limit ctq_ft_xw sends out a signal or the 6-second operation time ends;

[0052] S2, walking timer T0 pulse, enables the 2-minute remote control iron suction and discharge process timer T1. In the iron suction and discharge process of the iron remover, the process timer must be enabled to perform related actions;

[0053] S3, every 3 hours at 1 minute and 6 seconds (after the iron remover reaches the iron release position), a pulse is sent to enable the 1-minute iron release timer T2, thereby driving the iron remover to release iron ctq_lc. The set time includes the iron remover movement stabilization time and iron release time;

[0054] S4, every 3 hours at 2 minutes and 8 seconds (after the iron remover has finished releasing iron), a pulse is sent to enable the 6-second iron absorption timer T3, and at the same time enable the iron absorption operation signal ctq_xt_yx. At this time, the iron remover moves on the guide rail to the iron absorption position until the iron absorption infrared limit ctq_xt_xw sends a signal or the 6-second operation time ends;

[0055] S5, after the iron remover reaches the iron absorption position, when the T1 and T5 process timers are reset, the iron remover excitation signal ctq_lc is enabled, and the iron remover begins to enter the iron absorption state, waiting for the timing automatic iron remover signal or the manual remote control signal ctq_man_ctrl, and enters the next iron absorption and release operation cycle;
