Description

Technical Field

[0001] The invention relates to the technical field of coal washing, and in particular to an intelligent coal slime water system. Background Art

[0002] Coal preparation plants that use wet separation, coal slime water treatment is an important link. Usually, the coal slime water is concentrated by sedimentation in a concentrator, and the underflow pump pumps the underflow of the concentrator to the filter press. After filtration by the filter press, the coal slime and circulating water are recovered. Therefore, the recovery efficiency, chemical consumption and water consumption of coal slime are all key indicators for evaluating the treatment of coal slime water.

[0003] At present, most coal preparation plants use the following methods to add reagents to the concentrator:

[0004] 1. Manual dosing, that is, the preparation and addition of coagulants and flocculants are all done manually.

[0005] 2. The timing and quantitative addition of reagents is achieved by detecting the content of water-coal sludge in the overflow of the concentrator, the concentration of the underflow of the concentrator and the height of the clarification layer. The frequency of the dosing pump is set based on experience, or the dosage is controlled by controlling the switching time of the solenoid valve.

[0006] The current degree of automation in filter press operations is not high. Filter presses are often operated through on-site control cabinets, and many operating links rely on the observation and judgment of operators; the feeding is judged to be completed by observing that the filtered water does not form a line; when there is an upper limit on the number of units for joint unloading, the timing of unloading is controlled manually.

[0007] The above-mentioned coal slurry water treatment system mainly has the following problems.

[0008] 1. When adding drugs manually, the labor intensity of workers is high, and there are also problems such as untimely addition of drugs, inaccurate dosage, and high drug consumption;

[0009] 2. The detection time of overflow water from the concentrator is long and no real-time feedback can be given. Usually, workers have to rely on visual inspection to judge the sedimentation effect of the coal slurry water;

[0010] 3. The bottom flow test takes a long time and cannot provide real-time feedback to guide the adjustment of the dosage;

[0011] 4. Low intelligence and poor adaptability: With the fluctuation of coal quality, the properties of coal slurry water are also changing at any time. The fixed frequency value cannot meet the actual needs, so it is necessary to frequently manually adjust the dosing pump frequency or the solenoid valve switch time, which requires a large number of personnel;

[0012] 5. Concentrators, dosing machines, and filter presses can only be controlled locally and cannot be remotely monitored;

[0013] 6. The timing of feeding end is judged by human experience and operated manually;

[0014] 7. The unloading timing is manually controlled to control the amount of coal carried by the transfer belt.

[0015] In addition, the concentrator and filter press positions in most coal preparation plants are managed and operated separately, which leads to many problems on site not being communicated in a timely manner, reducing the treatment efficiency of coal sludge water and increasing chemical and water consumption.

[0016] In summary, in the prior art, the coal slime water treatment system has the problems of low intelligence and low overall efficiency. Summary of the invention

[0046] To facilitate understanding of this embodiment, an intelligent coal slurry water system disclosed in an embodiment of the present invention is first introduced in detail.

[0047] Embodiment 1:

[0048] Combination Figure 1 This embodiment is described in detail. The present invention provides an intelligent coal slurry water system, including a dosing mechanism, a filter pressing mechanism and a controller 107. The dosing mechanism and the filter pressing mechanism are respectively connected to the controller 107;

[0049] Specifically, the programmable logic controller PLC is selected as the controller of the intelligent coal slurry water system due to its flexible hardware configuration and convenient configuration.

[0050] The coal slime washing process goes through the steps of dosing, concentration filtration and filter pressing.

[0051] The dosing mechanism includes a concentrator, a dosing device and a first sensor, the dosing device is connected to the concentrator and the controller 107 respectively, the concentrator is connected to the first sensor, and the first sensor is connected to the controller 107;

[0052] During the dosing process, the dosing equipment includes a dosing device 101, a storage device 102, and a drug delivery device 103. The dosing device 101 is connected to the storage device 102, and the storage device 102 is connected to the drug delivery device 103.

[0053] The dosing device includes a dosing device 101, a material storage device 102, and a drug delivery device 103. The dosing device 101 is connected to the material storage device 102, and the material storage device 102 is connected to the drug delivery device 103.

[0054] The dosing device 101 includes a first frequency converter and a dosing pump group, the dosing pump group includes a dosing pump and a first drive motor, the dosing pump is connected to the first drive motor, and the first drive motor is connected to the first frequency converter;

[0055] The drug delivery device 103 includes a second frequency converter, a drug delivery pump group and a first solenoid valve. The drug delivery pump group includes a drug delivery pump and a second drive motor. The drug delivery pump and the second drive motor are connected. The second drive motor is connected to the second frequency converter. The second frequency converter is connected to the controller. The first solenoid valve is connected to the drug delivery pump. The first solenoid valve and the second frequency converter are respectively connected to the controller.

[0056] Specifically, the dosing mechanism is used to administer medicine to the filter press mechanism system, the function of the concentrating mechanism is to increase the concentration of coal and mud in the coal slurry water by dehydration, and the concentrator uses an underflow pump to pump the underflow to the filtering mechanism; the controller 107 controls the filter press mechanism and the dosing mechanism by connecting with the dosing mechanism and the filter press mechanism.

[0057] Specifically, the controller 107 controls the output frequency of the first frequency converter to control the speed of the first drive motor, the dosing pump pumps the medicine to the storage device 102, and the dosing pump pumps the medicine in the storage device 102 to the compressor to add medicine to the concentration system.

[0058] During the concentration and filtration process, the concentrator is the main actuator. By obtaining the state of the drug in the concentrator, the dosage of the dosing device is adjusted. Therefore, the concentrator is equipped with a first sensor, which is connected to the controller 107 to transmit the measured data to the controller 107.

[0059] The first sensor comprises:

[0060] 1) Concentrator feed flow meter: used to measure the feed flow of the concentrator;

[0061] 2) Concentrator feed density meter: used to measure the feed density of the concentrator;

[0066] The controller 107 summarizes the data collected by the first sensor and calls the feed time of the filter press. The controller 107 combines the data measured by the first sensor with the feed time, calculates the feed pump current at this feed time, obtains the dosage and controls the dosage. The frequency converter controls the dosage of the dosing mechanism by controlling the working time of the first solenoid valve and the output frequency of the second frequency converter.

[0067] Figure 2 It is a structural diagram of the filter press mechanism. After the dosing process is completed, the filter press stage is entered. The implementation of the filter press process mainly relies on the filter press mechanism. The feeding device includes a first feeding device 301 and a second feeding device 302. The first feeding device 301 includes a first feeding bucket and a second solenoid valve. The first feeding bucket is connected to the filter press through the second solenoid valve, and the second solenoid valve is connected to the controller 107; the second feeding device 302 includes a second feeding bucket and a third solenoid valve. The second feeding bucket is connected to the filter press through the third solenoid valve, and the third solenoid valve is connected to the controller 107.

[0068] The filter press mechanism comprises a filter press feeding power device 105 and a filter press device 106 . The filter press feeding power device 105 and the filter press device 106 are connected to each other. The filter press feeding power device 105 and the filter press device 106 and a controller 107 are connected to each other.

[0069] Specifically, the filter press device 106 includes a filter press plate, a trolley, and a motor. The controller 107 is connected to the motor via a frequency converter to control the reciprocating motion of the trolley on the filter press mechanism frame to achieve the operations of taking and pulling the plate.

[0070] The filter press feed power device 105 is installed at the feed end of the filter press device 106; the filter press feed power device 105 includes a filter press feed pump and an ammeter, and the filter press feed pump and the ammeter are connected.

[0071] The filter press mechanism further includes a filter press feeding device 104 , which is connected to a filter press feeding power device 105 of the filter press.

[0072] The filter press feeding device 104 includes a first feeding device 301 and a second feeding device 302;

[0073] The first feeding device 301 includes a first feeding bucket and a second solenoid valve, the first feeding bucket is connected to the filter press through the second solenoid valve, and the second solenoid valve is connected to the controller 107;

[0074] The second feeding device 302 includes a second feeding barrel and a third solenoid valve. The second feeding barrel is connected to the filter press via the third solenoid valve, and the third solenoid valve is connected to the controller 107 .

[0075] Furthermore, the filter press device 106 includes a filter press plate, a trolley, and a motor. The controller 107 is connected to the motor via a frequency converter to control the reciprocating motion of the trolley on the filter press mechanism frame to achieve the operation of pulling and pressing the plate.

[0076] Specifically, the filter press process mainly includes two processes: feeding and unloading. It can be further divided into pressing the filter plate, feeding, feeding completion, blowing, cycle waiting, plate taking, and plate pulling. After pressing the plate, in order to realize the feeding function, it is equipped with a first feeding bucket and a second solenoid valve. When feeding starts, the second solenoid valve is energized, and the filter press feeding pump starts to work, pumping the medicine to the filter press, and then blowing the medicine to prepare for unloading.

[0077] Figure 3 106 is a flow chart of sequential unloading. In actual production, multiple filter presses work in parallel. In this embodiment, there are 6 filter presses in total, and the filter presses can queue up for unloading intelligently. In order to achieve this requirement, an ammeter connected to the filter press feed pump is used to obtain the feed time through the current value of the feed pump. The feed end time can be obtained according to the underflow density of the concentrator and the feed time measured by the first sensor. At this time, the third drive motor drives the feed pump to start working. After the feed is completed, the blowing link begins. The blowing time of the medicinal material of the first filter press is judged according to the data transmitted to the controller 107 by the first sensor. When the predetermined time is reached, the filter press automatically starts to unload. After the unloading is completed, the filter press plate is compressed again, and the second filter press is judged at the same time. Whether the filter press can execute unloading, if yes, the next filter press starts unloading, and the first filter press starts to enter the automatic feeding process. In other words, the allowed unloading time of the second filter press is earlier than the unloading end time of the first filter press. When multiple filter presses work in parallel, if the first filter press enters the unloading process, and the second filter press has also finished blowing, in other words, if the allowed unloading time of the second filter press is earlier than the unloading end time of the first filter press, the second filter press enters waiting until the first filter press finishes unloading, and the second filter press can execute the unloading process. If not, the second filter press continues the current process, and so on. When the last filter press completes the unloading work, the working status of the first filter press is monitored.

[0078] In this embodiment, the sixth filter press completes the unloading work, obtains the feeding time of the first filter press and the feeding end time of the first filter press, and monitors the working status of the first filter press at the same time to determine whether the medicine material in the first filter press meets the unloading requirements. If so, the unloading process is started, if not, the current process is continued until the medicine material can execute the unloading process, and then the unloading is started. In this way, the intelligent queuing unloading of the six filter presses is realized.

[0079] The intelligent coal slurry water system disclosed in the present invention also has an automatic feeding function. In order to realize this function, the filter press feeding device 104 includes a liquid level sensor, which is installed on the first feeding barrel and is connected to the controller 107 .

[0080] The flowchart of automatic medication refill is as follows Figure 4 As shown, specifically, the threshold liquid level of the first feed barrel is preset first. If the feed barrel liquid level measured by the liquid level sensor is less than the preset threshold liquid level, it means that the medicine in the feed barrel is insufficient and needs to be supplemented. The filter press supplement device starts to supplement. At this time, the third solenoid valve is controlled to be energized, and the second feed barrel starts to supplement until the medicine liquid level in the first feed barrel is higher than the liquid level threshold. When the liquid level in the first feed barrel is higher than the set threshold liquid level, the third solenoid valve loses power and the second feed barrel stops supplementing. The setting of the liquid level threshold is related to the underflow concentration of the concentrator, the height of the clarification layer of the concentrator, and the number of filter presses that are open. The number of filter presses that are open is the number of filter presses currently working.

[0081] In order to improve the information interaction capability of the intelligent coal slurry water system and facilitate the control of the intelligent coal slurry water system, the controller 107 also includes a communication module, and the communication module is connected to the host computer.

[0082] Specifically, the communication module includes a WIFI module, a 4G module, a ZIGBEE, and an Ethernet module; in this embodiment, the intelligent coal slurry water system is equipped with a WIFI module; the host computer includes a mobile phone, a computer, and a Pad.

[0083] Specifically, the upper computer is connected to the controller 107 through the communication module. In this embodiment, the Pad is used to communicate with the controller 107 through the WIFI module. The working time of the dosing pump is controlled by controlling the working state of the first solenoid valve. At the same time, the frequency of the second drive motor of the dosing pump group is controlled to achieve control of the amount of medicine added. The output frequency of the second drive motor and the working time of the dosing pump group are set by the Pad. At the same time, the output frequency of the second drive motor of the dosing pump can be automatically set through accumulated experience data and big data to achieve unmanned management of the dosing equipment.

[0084] The intelligent coal slurry water system provided by the present invention has the following advantages.

[0085] 1) Automatic dosing: The feeding time is determined by the current value of the third drive motor, and the dosage is obtained by the feeding time and the value measured by the first sensor. The working time of the dosing pump is automatically set through big data and experience data to achieve unmanned management and automatic control of dosing.

[0086] 2) Automatic feeding: Monitor the material unloading status according to the end time of feeding, and automatically enter the refilling process when the unloading is completed.

[0087] 3) Queueing and unloading in sequence: By monitoring the working status of the filter press, the unloading process of the filter press is controlled, so that multiple filter presses can queue up and unload in sequence.

[0088] 4) Automatic feeding: The liquid level threshold of the filter press feeding device 104 is set by the underflow concentration of the concentrator, the height of the clarification layer of the concentrator, and the number of filter press openings. At the same time, the filter press feeding device 104 is equipped with a liquid level sensor. The liquid level measured by the sensor is compared with the liquid level threshold to determine whether to start the feeding process.

[0089] 5) Mobile intelligent monitoring: Use Pad, mobile phone, computer to connect to the control terminal, and set the working time of the drug delivery pump of the drug delivery system and the threshold of the output frequency of the second frequency converter. In addition, big data and experience values ​​can be used to automatically set the working time of the drug delivery pump and the output frequency threshold of the output frequency of the second frequency converter to achieve unmanned management of the equipment.
