Description

Technical Field

[0001] The present application relates to the field of coal technology, and in particular to a method, system, electronic device and storage medium for self-balancing density control of a coal washing medium. Background Art

[0002] After mining, coal requires washing, a process that involves removing gangue and other impurities from the coal. Coal washing generally utilizes the different physical properties of coal and gangue, separating the coal from impurities in media of varying densities or characteristics. Washed coal, free of gangue and other impurities, exhibits advantages such as low sulfur, ash, and moisture content, high calorific value, and clean, efficient utilization. Media density is a crucial parameter in coal washing, directly impacting washing accuracy, efficiency, and product quality.

[0003] In existing technologies, coal washing media density control is primarily achieved manually. A forklift or grab bucket is used to pour the media into a media pit, and water is then added to the pit based on manual experience. Once the media is evenly mixed, it is sent to a laboratory for testing. Based on the test results, adjustments are then made until the media density meets the requirements. Consequently, existing media density adjustment requires significant manpower and time, resulting in low efficiency and poor accuracy. Summary of the Invention

[0048] Figure 1 A schematic diagram of the structure of a coal washing medium density control system provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the coal washing medium density control system may include a host computer 1, a control device 2, a stirring device 3, a density measuring device 4, a liquid level measuring device 5, a bin level measuring device 6, a feeding device 7 and a water supply device 8, wherein the stirring device 3, the density measuring device 4, the liquid level measuring device 5, the bin level measuring device 6, the feeding device 7 and the water supply device 8 are all communicatively connected to the host computer 1 through the control device 2.

[0049] Optionally, the host computer 1 can be connected to the control device 2.

The liquid level measuring device 5 can also be set at the inner wall of the medium pool to measure the liquid level information of the medium prepared in the medium pool.

[0052] The position measuring device 6 can be used to measure the medium position information in the medium library, and report the medium position information to the host computer 1 through the control device 2. The position measuring device 6 can be specifically set at a certain position in the medium library to measure the medium position information in the medium library, wherein the medium library refers to the warehouse for storing media. When the media needs to be allocated, the required amount of media is collected from the media library.

[0053] The stirring device 3 can be used to stir the medium and water in the medium pool. The stirring device 3 can be set in the medium pool. When the medium is prepared, the stirring device 3 is used to stir the medium in the medium pool evenly.

[0054] The feeding device 7 can be used to output the medium in the medium reservoir to the medium pool. Specifically, the feeding device 7 can be set in the medium reservoir.

The camera 9 may be used to collect image information of the area where the coal washing medium density control system is located and report the collected image information to the host computer 1 through the control device 2.

[0056] Optionally, the host computer 1 can be, for example, an electronic device, specifically, a terminal device with computing and display capabilities, such as a laptop, a PDA, or a desktop computer, or a server. The host computer can use the method of the embodiment of the present application to control the density of the coal washing medium and adjust the medium density to meet the requirements.

[0057] Figure 2 The flow chart of a method for controlling the density of a coal washing medium by self-balancing means provided in the embodiment of the present application is shown in FIG. The execution subject of the method is the aforementioned host computer. Figure 2 As shown, the method includes:

[0058] S101. After receiving the power-on command, the host computer sends a stirring command to the stirring device.

[0059] The startup command can be a scheduled startup command pre-set in the coal washing medium density control system, such as setting the startup operation at 11:00 PM every night or 1:00 PM every day, without limitation. Alternatively, the startup command can be a startup command entered by the user on the host computer based on actual production needs. The startup command can be used to indicate the need for medium allocation.

[0060] Optionally, after receiving the power-on instruction, the host computer 1 may first generate a stirring instruction, and then send the generated stirring instruction to the stirring device 3 connected to the control device 2 through the control device 2 .

[0061] Optionally, when the stirring device 3 receives a stirring instruction, it performs a stirring operation to stir the medium liquid in the medium pool evenly.

[0062] S102: After receiving the successful response reported by the stirring device, the host computer sends measurement instructions to the density measuring device, the liquid level measuring device, the bin level measuring device and the water supply device respectively.

[0063] Optionally, the successful response reported by the stirring device 3 refers to a response that the medium liquid in the medium pool is stirred evenly. When the stirring device 3 stirs the medium liquid in the medium pool evenly, the control device 2 returns a successful response to the host computer 1. After receiving the successful response reported by the stirring device 3, the host computer 1 sends measurement instructions to the density measuring device 4, the liquid level measuring device 5, the storage level measuring device 6, and the water supply device 8 respectively through the control device 2.

[0064] Specifically, the host computer 1 can send a density measurement instruction to the density measuring device 4. After receiving the density measurement instruction, the density measuring device 4 measures the medium density information of the medium liquid in the current medium pool. At this time, the medium density information in the current medium pool may refer to the medium density after being stirred evenly by the stirring device 3.

[0065] Optionally, the host computer 1 can send a liquid level measurement instruction to the liquid level measuring device 5. When the liquid level measuring device 5 receives the liquid level measurement instruction, it measures the liquid level of the medium in the medium pool and reports the measured liquid level information to the host computer 1 through the control device 2.

[0066] Optionally, the host computer 1 may send a position measurement instruction to the position measurement device 6. When the position measurement device 6 receives the position measurement instruction, it measures the media position in the media library and reports the measured media position information to the host computer 1 through the control device 2.

[0067] Optionally, the host computer 1 can send a water pressure measurement instruction to the water supply device 8. When the water supply device 8 receives the water pressure measurement instruction, it measures the water pressure information and reports the measured water pressure information to the host computer 1 through the control device 2.

[0068] S103. The host computer determines the amount of medium and water to be added based on the medium density information reported by the density measuring device, the liquid level information measured and reported by the liquid level measuring device, the medium position information reported by the position measuring device, and the water pressure information reported by the water supply device.

[0069] Optionally, since the density measuring device 4 measures the density of the medium in the current medium pool and the liquid level measuring device 5 also measures the liquid level information of the medium in the current medium pool, the upper computer 1 can calculate the amount of medium to be added and the amount of water to be added based on the medium density information reported by the density measuring device 4, the liquid level information reported by the liquid level measuring device 5, the target medium density to be prepared, and the target medium preparation amount.

[0070] For example, if the target medium mixing amount is to fill the medium pool, the medium pool is 10 cubic meters, and the liquid level reported by the liquid level measuring device 5 is 30%, then 70% of the water volume is required to fill the entire medium pool, that is, 7 cubic meters of water to be added. If the target medium density is 1g / L, then the amount of medium to be added is 7000L×1g / L=7kg.

[0071] Optionally, the host computer 1 may determine whether the medium amount and water pressure in the medium position information are sufficient based on the medium position information reported by the position measurement device and the water pressure information reported by the water supply device.

[0072] S104: The host computer controls the feeding device and the water supply device according to the amount of the medium to be added and the amount of water to be added.

[0073] Optionally, after the host computer 1 determines the amount of medium to be added and the amount of water to be added, it can control the feeding device 7 to add the medium to the medium pool, and control the water supply device 8 to add water to the medium pool.

[0074] In this embodiment, a host computer sends measurement instructions to each device and determines the amount of medium and water to be added based on the received measurement information. Simultaneously, the feeding device and the water supply device are controlled based on the determined amount of medium and water to be added. This allows for automatic adjustment of the medium density by the host computer throughout the entire process, enabling online automatic control between the devices and avoiding the manual operation required in the prior art, saving manpower, material resources, and adjustment time. Furthermore, controlling the feeding device and the water supply device based on the amount of medium and water to be added ensures high accuracy in medium density adjustment.

[0075] Figure 3 A flow chart of another method for controlling the density of a coal washing medium by self-balancing means is provided in an embodiment of the present application. Figure 3 As shown, before sending the stirring instruction to the stirring device in S101, the following steps may be included:

[0076] S201: The host computer controls the camera to collect image information through the control device.

[0077] The camera can be set in the area where the coal washing medium density control system is located, and can collect environmental information of the area where the coal washing medium density control system is located.

[0078] Optionally, when the upper computer 1 receives the power-on command, it first sends an image acquisition command to the camera connected to the control device 2 through the control device 2. After receiving the image acquisition command, the camera can collect the environment of the area where the coal washing medium density control system is located. For example, it can collect image information for 1 minute and report the collected image information to the upper computer 1 through the control device 2.

[0079] S202: The host computer determines whether to send a stirring instruction to the stirring device based on the image information collected by the camera.

[0080] Optionally, the image information collected by the camera may include environmental information within a period of time, for example, whether there are other staff members in the media pool area.

[0081] Optionally, in S202 above, the host computer determines whether to send a stirring instruction to the stirring device according to the image information collected by the camera, which may include:

[0082] Optionally, if the host computer 1 determines that the target object does not exist in the received image information, it determines to send a stirring instruction to the stirring device 3; if the host computer 1 determines that the target object exists in the received image information, the host computer 1 generates and outputs a first alarm message, wherein the first alarm message is used to prompt the user to check. The target object can be, for example, a staff member or an animal such as a puppy or kitten. If the target object exists, it indicates that there is a safety hazard in the area where the coal washing medium density control system is located. In this case, the host computer 1 generates and outputs a first alarm message to prompt the staff member to check and wait until the safety hazard is eliminated before starting the machine.

[0083] In this embodiment, by performing automatic safety monitoring before starting the computer, the safety of starting the computer can be guaranteed.

[0084] Optionally, before the upper computer controls the feeding device and the water supply device according to the amount of the medium to be added and the amount of water to be added in S104, the following steps may be included:

[0085] Optionally, the upper computer 1 can determine whether the media position information meets the preset media position condition based on the media position information reported by the position measurement device 6 and the amount of media to be added, wherein the preset media position condition refers to the media position information being greater than or equal to the amount of media to be added.

[0086] Optionally, if the host computer 1 determines that the media bin position information does not meet the preset media bin position conditions, the host computer 1 generates and outputs a second alarm message, wherein the second alarm message can be used to indicate that the media bin position is insufficient, thereby reminding staff to check or add media to the media library. If the host computer 1 determines that the media bin position information meets the preset media bin position conditions, the control device 2 can control the feeding device 7 to add media to the media pool.

[0087] Optionally, the host computer 1 can determine whether the water supply pressure information meets the preset water pressure condition based on the water supply pressure information reported by the water supply device 8, wherein the preset water pressure condition can be set according to actual conditions, for example, water can be supplied to the medium pool only when the water pressure meets 5MP.

[0088] Optionally, when the host computer 1 determines that the water supply pressure information does not meet the preset water pressure condition, the host computer 1 generates and outputs a third alarm message, wherein the third alarm message is used to indicate insufficient water pressure, which can remind staff to check and wait until the water pressure meets the preset water pressure condition before water can be supplied to the medium pool. If the host computer 1 determines that the water supply pressure information meets the preset water pressure condition, the host computer 1 can control the water supply device 8 through the control device 2 to supply water to the medium pool.

[0089] In this embodiment, by obtaining medium position information and water pressure information, it is possible to ensure that there is sufficient medium and water in system production, thereby avoiding production delays caused by lack of medium and water.

[0090] Optionally, in the above S104, the upper computer controls the feeding device and the water supply device according to the amount of the medium to be added and the amount of water to be added, which may include:

[0091] Optionally, the host computer 1 can determine the ratio of the medium amount to water according to the amount of medium to be added and the amount of water to be added, and control the feeding device 7 to output the medium into the medium pool and control the water supply device 8 to supply water to the medium pool according to the ratio of the medium amount to water.

[0092] The feeding device 7 can be a quantitative feeding device, and the water supply device 8 can be a quantitative water supply device. The amount of medium to be added and the amount of water to be added can be added in sequence according to the ratio of the medium to the water. For example, if the ratio of the medium to the water is 1:1, specifically, 1 L of water is added to 1 kg of medium, then the host computer can control the water supply device 8 to supply 1 L of water to the medium pool every time the feeding device 7 outputs 1 kg of medium.

[0093] Figure 4 A flow chart of another method for controlling the density of a coal washing medium by self-balancing means is provided in the embodiment of the present application. Figure 4 As shown, after controlling the feeding device to output the medium into the medium pool and controlling the water supply device to supply water to the medium pool according to the ratio of the medium amount to the water amount, the following steps may be included:

[0094] S301. The host computer controls the stirring device through the control device to stir the added medium and water, and sends a real-time measurement instruction to the density measuring device.

[0095] Optionally, after the upper computer 1 controls the feeding device 7 to output the medium into the medium pool and controls the water supply device 8 to supply water to the medium pool according to the ratio of the medium amount to the water amount, the upper computer 1 can send a stirring instruction to the stirring device 3, and the stirring device 3 performs the stirring operation after receiving the stirring instruction. At the same time, the upper computer 1 sends a real-time measurement instruction to the density measuring device 4. After receiving the real-time measurement instruction, the density measuring device 4 measures the density of the medium liquid being stirred in the medium pool, and reports the real-time measured medium density information to the upper computer 1.

[0096] Optionally, when the feeding device is controlled to add medium and the water supply device is controlled to add water according to the ratio of the medium amount to the water amount, the actual medium density obtained after actual stirring may deviate from the density of the medium added in proportion. Therefore, a density measuring device is required to measure the medium density in real time during the actual stirring process to obtain real-time medium density information during stirring.

[0097] S302: The host computer obtains real-time medium density information measured by the density measuring device in real time.

[0098] S303. The host computer adjusts the ratio of the medium volume to the water volume according to the real-time medium density information, and controls the feeding device to output the medium to the medium pool and controls the water supply device to supply water to the medium pool according to the adjusted ratio of the medium volume to the water volume.

[0099] Optionally, the host computer 1 compares the acquired real-time medium density information with the target medium density, adjusts the ratio of the medium volume to the water volume in a timely manner according to the comparison result, and controls the feeding device to output the medium to the medium pool and controls the water supply device to supply water to the medium pool according to the adjusted ratio of the medium volume to the water volume.

[0100] Specifically, if the real-time medium density is lower than the target medium density, the amount of medium to be added can be increased to improve the ratio of the medium amount to water; if the real-time medium density is higher than the target medium density, the amount of water to be added can be increased to reduce the ratio of the medium amount to water.

[0101] In this embodiment, during the process of mixing the medium, real-time medium density information is obtained to continuously adjust the ratio of the added medium to the water amount, thereby mixing a qualified medium density, which can make the mixed medium density more accurate.

[0102] The embodiment of the present application also provides a coal washing medium density control system. Figure 1 As shown, it includes: a host computer, a control device, a stirring device, a density measuring device, a liquid level measuring device, a bin level measuring device, a feeding device and a water supply device.

The electronic device may be, for example, the host computer described in the aforementioned embodiment. Figure 5 As shown, the electronic device may include: a processor 401 and a memory 402.

[0105] Optionally, a bus 403 may also be included, wherein the memory 402 is used to store machine-readable instructions executable by the processor 401. When the electronic device 400 is running, the processor 401 communicates with the memory 402 through the bus 403. When the machine-readable instructions are executed by the processor 401, the method steps in the above method embodiment are performed.

[0106] The embodiment of the present application further provides a computer-readable storage medium, on which a computer program is stored.
