Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of device control, and in particular to a control method and system of a high-frequency vibrating screen mesh cleaning system and a storage medium. BACKGROUND

[0002] The grinding classification process of the Yiliang Chihong Concentrator currently uses a combination of a spiral classifier and a high-frequency vibrating fine screen. The application of the high-frequency vibrating fine screen has solved the industry problem of over-grinding of fine particles and under-grinding of coarse particles in the grinding classification process, and has stabilized the concentration and fineness of the grinding.

[0003] Due to the influence of changes in the properties of deep mine ore, the high-frequency vibrating fine screen is prone to scaling and clogging of the screen mesh during use, resulting in a decrease in screening efficiency from the designed 70% to below 40%. In addition, scaling and clogging of the screen mesh can cause a series of adverse effects such as non-compliance of the concentrate grade and increased power consumption of the mill medium.

[0004] In related technical solutions, a high-concentration acidic solution is usually used to clean the high-frequency vibrating fine screen. However, since the material of the high-frequency vibrating fine screen is usually polyurethane, the high-concentration acidic solution can cause the material of the screen mesh to become brittle, which shortens the service life of the screen mesh. In addition, the traditional acidic solution pouring action needs to be completed by a worker, so there is a need for a cleaning method for the high-frequency vibrating fine screen that does not rely on high-concentration acidic cleaning solution.

[0005] The above content is only used to assist in understanding the technical solutions of the present application and does not represent an acknowledgement that the above content is prior art. SUMMARY

[0084] Based on the hardware architecture of the high-frequency vibrating screen mesh cleaning system based on the above-mentioned device control technology, embodiments of the control method of the high-frequency vibrating screen mesh cleaning system are proposed.

[0085] First embodiment

[0086] In this embodiment, the high-frequency vibrating screen mesh cleaning system includes a cleaning device and a control unit, the cleaning device includes a mesh placing frame provided with a pressure sensor at the bottom of the frame, an acid pouring device, a water adding device, a gas backflushing device provided at the bottom of the mesh placing frame, and at least two ultrasonic generators symmetrically arranged at the lower side of the mesh placing frame.

[0087] The gas backflushing device is used to emit gas flow from the bottom of the mesh placing frame to clean the mesh from the bottom, and the main purpose is to flush the particles on the mesh out of the mesh holes; the ultrasonic generator is used to emit ultrasonic waves from the lower side of the mesh placing frame to help separate and clean the particles with strong adhesion on the mesh;

[0088] The bottom of the mesh placing frame is provided with a pressure sensor, and when the mesh is placed in the mesh placing frame, the mesh applies a downward force to the bottom of the frame, and the reading of the pressure sensor is the mass of the mesh.

[0089] The openings of the acid pouring device and the water adding device are arranged higher than any position of the mesh placing frame, so as to ensure that the acid pickling solution in the acid pouring device and / or the water in the water adding device can be poured into the mesh placing frame.

[0090] Exemplarily, in a specific embodiment, the screen placement frame can be made of stainless steel, and has a size of 0.8 m*2 m*1.2 m. The ultrasonic generators are arranged at positions 0.5 m away from the wide side and 0.3 m away from the long side of the groove body at the bottom of the screen placement frame, and one is arranged on each of the left and right sides. Eight filter plates are evenly laid on the screen placement frame. In order to ensure uniform gas production, a gas pipe with a diameter of 10 mm is connected to the filter plates arranged uniformly at the bottom of the screen placement frame, so that the flushing gas is injected into the screen placement frame through the filter plates.

[0091] With reference to Figure 2 The control method of the high-frequency vibration screen cleaning system includes the following steps:

[0092] In step S10, the screen quality collected by the pressure sensor is obtained.

[0093] In step S20, it is determined whether the screen quality is in a preset cleaning interval, wherein the preset cleaning interval is multiple.

[0094] In this embodiment, the material of the screen is polyurethane screen. In this embodiment, the screen is placed flat in the screen placement frame. The pressure data collected by the pressure sensor arranged at the bottom of the frame is taken as the screen quality. Then, it is determined whether the screen quality is in a preset cleaning interval.

[0095] In this embodiment, the preset cleaning interval is set to multiple. The interval values of the cleaning intervals are different. When the screen quality is in a smaller preset cleaning interval, the control parameters of each device in the subsequent cleaning strategy are smaller, and the concentration and amount of the pickling agent used are smaller. When the screen quality is in a larger preset cleaning interval, it means that the dirt quality on the screen is larger. Therefore, the control parameters of each device in the cleaning strategy are larger than those in the smaller preset cleaning interval, and the concentration and amount of the pickling agent used are also larger.

[0096] In step S30, when the screen quality is in the preset cleaning interval, the target pickling liquid pouring amount, the target pickling liquid concentration, the target ultrasonic power, and the target gas backflushing time length are determined based on the screen quality.

[0097] In this embodiment, when the screen quality is in the preset cleaning interval, it is determined that the screen meets the cleaning condition. At this time, the target pickling liquid pouring amount, the target pickling liquid concentration, the target ultrasonic power, and the target gas backflushing time length are determined based on the screen quality.

[0098] The target pickling liquid pouring amount is the solution amount of the pickling liquid in the pickling device introduced into the screen placement frame. The pickling device stores at least two concentrations of pickling liquid. The appropriate concentration of pickling liquid is selected as the pickling liquid concentration according to the screen quality.

[0099] The target ultrasonic power is a target operating power of the ultrasonic generator, and the target air backwashing duration is an operating duration of the air backwashing device under the constant power.

[0100] In this embodiment, the screen mass is positively correlated with the target pickling liquid pouring amount, the target pickling liquid concentration, the target ultrasonic power, and the target air backwashing duration.

[0101] In step S40, a target control strategy is determined according to the target pickling liquid pouring amount, the target pickling liquid concentration, the target ultrasonic power, and the target air backwashing duration.

[0102] In step S50, the acid pouring device, the water adding device, the air backwashing device, and the ultrasonic generator are controlled to operate based on the target control strategy.

[0103] In this embodiment, after the target pickling liquid pouring amount, the target pickling liquid concentration, the target ultrasonic power, and the target air backwashing duration are determined, the control strategy of the entire high-frequency vibrating screen screen cleaning system, i.e., the control parameters of the acid pouring device, the water adding device, the air backwashing device, and the ultrasonic generator, are determined based on these parameters.

[0104] Specifically and optionally, the acid pouring device is first controlled to pour pickling liquid meeting the target pickling liquid pouring amount and the target pickling liquid concentration into the screen placing device. Optionally, the acid pouring device includes at least two acid pouring ports storing pickling liquid of different concentrations, a target acid pouring port storing pickling liquid of the target pickling liquid concentration is determined, and a target opening duration of the target acid pouring port meeting the target pickling liquid pouring amount is determined. The target acid pouring port is controlled to be opened for the target opening duration to pour pickling liquid meeting the target pickling liquid pouring amount into the screen placing device, and the target acid pouring port is controlled to be closed.

[0105] It should be noted that in this embodiment, a valve is arranged on the acid pouring port, and the valve has two states of opening and closing. Therefore, the pickling liquid flow rate in the acid pouring port per unit time is constant, and thus the pouring amount of pickling liquid can be determined according to the opening duration.

[0106] For example, according to the screen mass, 6% BK810E pickling liquid is selected as the target pickling liquid concentration, and the corresponding target pickling liquid pouring amount is 9.6 L. The valve on the acid pouring port flows out 2 L of pickling liquid per second, and thus the acid pouring port is controlled to be opened for 4.8 seconds and then closed.

[0107] Optionally, the valve of the water adding device is opened to add water to the first preset height and then closed while the acid is poured or before the acid is poured, so as to reduce the concentration of the pickling solution and reduce the structural corrosion of the polyurethane screen.

[0108] Exemplarily, the first preset height can be a position 0.1 m higher than the upper surface of the screen placing frame.

[0109] Further, after the action of pouring the acid and adding water for the first time is completed, the screen is soaked in the diluted pickling solution for a preset time length to preliminarily dissolve the dirt on the screen, and then the valve of the water adding device is opened to add water to the second preset height and then closed, so as to further reduce the concentration of the pickling solution to prevent structural corrosion of the screen and enable the subsequently generated ultrasonic waves to be completely submerged in water, thereby improving the cleaning effect of the ultrasonic waves. Optionally, a water level sensor can be installed at the second preset height in the screen placing frame, and when the water level sensor collects a water level signal, it is determined that the water has been added to the second preset height.

[0110] Exemplarily, the second preset height can be a position 0.5 m higher than the upper surface of the screen placing frame, and the preset time length can be 20 min.

[0111] Further, after the action of adding water for the second time is completed, the ultrasonic wave generator is controlled to operate at a target ultrasonic wave power, and the air backflush gun is controlled to be opened at a preset power for a target air backflush time length, so as to use the cavitation effect, acceleration effect and direct flow effect of the ultrasonic waves in the liquid to disperse and peel the screen clogging material to achieve the effect of removing the clogging material, and simultaneously open the air backflush to accelerate the flow of water and impact the particles on the surface of the screen, thereby continuously flushing the screen by using the impact effect.

[0112] Finally, when the air backflush gun meets the target air backflush time length, the ultrasonic wave generator and the target air backflush are controlled to be closed to end the cleaning.

[0113] In the technical scheme provided in this embodiment, the screen is flushed by the screen flushing system combined with ultrasonic wave and air backflush, and according to the screen clogging condition, appropriate pickling agent concentration, agent amount, ultrasonic wave opening power and air backflush opening time length are selected, so as to realize efficient, low-cost and environmentally friendly cleaning of the screen.

[0114] Second embodiment

[0115] Reference Figure 3 Based on the first embodiment, in this embodiment, the step S30 comprises:

[0116] Step S31, determining a target preset cleaning interval of the screen quality, the target preset cleaning interval including a first target preset cleaning interval and a second target preset cleaning interval, the first target preset cleaning interval being smaller than the second target preset cleaning interval;

[0117] Step S32, determining a target acid pickling solution concentration associated with the target preset cleaning interval;

[0118] Step S33, determining a target acid pickling solution pouring amount according to the target acid pickling solution concentration and the screen quality;

[0119] Step S34, determining a target ultrasonic power and a target air backflushing time length according to the target acid pickling solution concentration and the target acid pickling solution pouring amount.

[0120] As an optional embodiment, in the embodiment, the preset cleaning interval can include a first target preset cleaning interval and a second target preset cleaning interval, the first target preset cleaning interval being smaller than the second target preset cleaning interval.

[0121] When the screen quality is in the smaller first target preset cleaning interval, it means that the dirt quality on the screen reaches the cleaning standard, and the control parameters in each device of the subsequent cleaning strategy are smaller, and the acid pickling reagent concentration is smaller. When the screen quality is in the larger second target preset cleaning interval, it means that the dirt quality on the screen is larger, and the control parameters in each device of the cleaning strategy are larger than those in the first target preset cleaning interval, and the acid pickling reagent concentration is also larger.

[0122] It can be understood that the first target preset cleaning interval and the second target preset cleaning interval in the embodiment are intervals divided based on two states of the dirt quality on the screen, and the first target preset cleaning interval and the second target preset cleaning interval can be single or multiple, which can be adjusted according to actual conditions, and the embodiment is not limited.

[0123] Optionally, in the embodiment, the target preset cleaning interval is associated with a corresponding target acid pickling solution concentration, and the screen in the quality interval corresponds to an acid pickling solution of a certain concentration. When the screen quality is in the first target preset cleaning interval, the target acid pickling solution concentration is determined as a first target acid pickling solution concentration; when the screen quality is in the second target preset cleaning interval, the target acid pickling solution concentration is determined as a second target acid pickling solution concentration; wherein the first target acid pickling solution concentration is smaller than the second target acid pickling solution concentration. If the screen quality is smaller than the lower limit of the first target preset cleaning interval, it is judged that the screen quality is not in the preset cleaning interval.

[0124] Exemplarily, the first target preset cleaning interval is set as [1.56kg, 2kg], corresponding to the BK810E pickling solution with a concentration of 4%, and the second target preset cleaning interval is set as [2kg, 2.5kg] U [2.5kg+], corresponding to the BK810E pickling solution with a concentration of 6%.

[0125] According to the target pickling solution concentration and the screen mass, the target pickling solution pouring amount is determined, and according to the target pickling solution concentration and the target pickling solution pouring amount, the target ultrasonic power and the target gas backflushing time length are determined.

[0126] Specifically and optionally, the target pickling solution pouring amount = first weight coefficient * (screen mass) * (target pickling solution concentration) + basic pouring amount;

[0127] The target ultrasonic power = second weight coefficient * (target pickling solution concentration) + basic ultrasonic power;

[0128] The target gas backflushing time length = third weight coefficient * (target pickling solution pouring amount) + minimum backflushing time length.

[0129] As an example, the calculation formula can be as follows:

[0130] The target pickling solution pouring amount = 0.02 * (screen mass) * (target pickling solution concentration) + 300;

[0131] The target ultrasonic power = 0.5 * (target pickling solution concentration) + 40

[0132] The target gas backflushing time length = 0.1 * (target pickling solution pouring amount) + 10

[0133] In the technical scheme provided in the embodiment, by determining the target preset cleaning interval in which the screen mass is located, the control system can accurately control the cleaning parameters according to the actual situation, and ensure that the cleaning effect meets the requirements; according to the different screen mass and preset cleaning interval, the target pickling solution concentration and the cleaning parameters are dynamically adjusted, so that the system can flexibly adapt to screens with different masses; and by calculating the target pickling solution pouring amount, the target ultrasonic power and the target gas backflushing time length, the system can optimize the cleaning process, and ensure the rationality of the cleaning liquid amount, the ultrasonic power and the gas backflushing time length, thereby improving the cleaning efficiency and reducing resource waste.

[0134] In addition, with reference to Figure 4 , the embodiment also provides a control device of a high-frequency vibrating screen screen cleaning system, which comprises:

[0135] The acquisition module 100 is configured to acquire the screen mass collected by the pressure sensor.
