[0001] This invention relates to the field of auxiliary equipment technology for coal mining, and in particular to a single-stroke pressure filter coal-water separation device and its usage method. Background Technology

[0002] High-pressure water jet technology is widely used in coal mining due to its high efficiency and environmental friendliness. However, the accompanying problem of dewatering coal-water slurry severely restricts resource recovery efficiency. Traditional sun-drying dewatering methods suffer from low efficiency and significant safety hazards in dealing with this type of coal-water slurry, necessitating the development of intelligent dewatering equipment.

[0003] Mechanical filter press has the advantages of adjustable pressure and large throughput, making it an efficient method for separating coal-water slurry. However, existing filter press devices have many shortcomings: the working conditions of continuous coal-water slurry production are not compatible with the filter press, which can easily lead to feed interruption or accumulation; the pressure and stroke control accuracy is low, resulting in unstable separation efficiency; the filter plates are inconvenient to install and disassemble, leading to high maintenance costs; and the equipment vibrates significantly during operation, resulting in insufficient stability and affecting its service life. Summary of the Invention

[0010] Furthermore, the drive system also includes a hydraulic control valve group for adjusting the pressure of the hydraulic cylinder, with the filter pressure adjustment range being 0.6~1.2MPa; the bottom of the filter chamber is provided with a water outlet corresponding to the position of the filter plate.

[0011] Furthermore, the control system includes a PLC control unit and a sensing system; the PLC control unit adopts a PID closed-loop control algorithm, and the sensing system includes a piezoresistive pressure sensor for monitoring the filter press pressure.

[0012] Furthermore, the support system includes a four-point box-type welding frame, rubber vibration damping pads installed at the connection between the welding frame and the main body of the device, and adjustable anchor bolts for adjusting the horizontal height of the equipment.

[0013] According to another objective of the present invention, the present invention provides a method of using the above-described single-stroke pressure filter press coal-water separation device, comprising the following steps: S1: The coal-water slurry enters the storage system through the feeding system for buffering and temporary storage; S2: When the filter press system is ready, the storage system delivers the coal-water slurry to the filter press chamber of the filter press system; S3: The drive system drives the movable filter plate of the filter press system to perform a single-stroke filter press action, squeezing out the water in the coal-water slurry through the filter plate and filter screen, and the filtrate is discharged through the water outlet hole; S4: After the filter press is completed, the solid discharge system is turned on, and the drive system drives the movable filter press plate to push the dewatered solid coal out of the filter press chamber. S5: After the material discharge is completed, the solid discharge system is shut down, and the device is ready to enter the next working cycle; The control system monitors and automatically coordinates the operation of each device in control steps S1 to S5 throughout the entire process.

Simultaneously, the modular design combines the advantages of precise and controllable filter pressure, easy maintenance of filter plates, and stable and reliable equipment operation, ultimately achieving a comprehensive technical effect of improving coal-water separation efficiency, ensuring continuous production, and reducing operating energy consumption.

[0034] Example 2 like Figure 1 As shown, this embodiment, based on Embodiment 1, provides a single-stroke pressure filter coal-water separation device, specifically including a feeding system 1, a storage system 2, a pressure filter system 3, a solid discharge system 4, a drive system 5, a control system 6, and a support system 7. Wherein: The feeding system 1 includes a conical feeding funnel 11, a feeding pipe 13, and an electromagnetic flow meter 14.

[0035] The storage system 2 includes a dual-compartment buffer storage tank 21, which is a parallel structure with an effective volume of 2m³. 3 The material is Q235B with a rubber lining, which has corrosion resistance. The capacitive liquid level sensor 23 and pressure sensor 24 inside the tank monitor the liquid level and pressure in real time. When the liquid level in a single tank reaches 80% of the upper limit, the PLC control unit 61 controls the three-way reversing valve 25 to switch to another slurry storage tank for feeding. The stirring device 22 is a double-layer open turbine straight blade impeller with a diameter of 430mm. It is driven by a Y2-200L2-6 motor (37kW, 970r / min) and a ZLY160-3.15 reducer, with a final output speed of 308r / min to prevent coal particles from settling. The variable frequency speed control screw pump 26 serves as the power source, and the speed is adjusted by a PID closed-loop control algorithm. The combination of pneumatic butterfly valve 27 and check valve 28 prevents material backflow.

[0036] The filter press system 3 includes a filter press chamber 31 and a filter plate 32. The filter press chamber 31 is a cubic structure of 1500×640×640mm, which has uniform stress distribution and high space utilization. The filter plate 32 is made of glass fiber reinforced polypropylene with a thickness of 90mm. The filter plate 32 and filter screen 33 are installed using an interlocking process, ensuring good sealing and stability.

The hinge mechanism 42 has an opening angle of 180°, which ensures smooth discharge and provides operating space for the loading, unloading and cleaning of the filter plate 32 and the filter screen 33.

[0038] The hydraulic cylinder 51 of the drive system 5 pushes the movable filter plate 34 to achieve single-stroke filtration, and the hydraulic control valve group 52 precisely adjusts the pressure and stroke.

[0039] The PLC control unit 61 of the control system 6 is a Siemens S7-1200, which adopts a 10Hz control algorithm and PID closed-loop control.

[0040] The four-point box-type welded frame 71 of the support system 7 is made of Q345D steel with a yield strength of not less than 345MPa and a tensile strength of 470-630MPa, possessing excellent mechanical properties. The rubber vibration isolation pads 72 between the welded frame and the filter chamber 31 prevent resonance. The adjustable anchor bolts 73 use trapezoidal threads Tr40×7, allowing for height adjustment within a 20cm range to ensure horizontal installation of the equipment.

[0041] like Figure 5 As shown, the working process of this device is as follows: The coal-water slurry produced by high-pressure water jet mining enters through a conical feed funnel 11. The ultrasonic anti-blocking vibrator 12 works to prevent blockage. The coal-water slurry is injected into a double-compartment buffer storage tank 21 through a three-way reversing valve 25. The capacitive liquid level sensor 23 and the pressure sensor 24 monitor the state inside the tank in real time. When the liquid level in one tank reaches 80%, the three-way reversing valve 25 switches to another tank, and at the same time, the stirring device 22 is started to prevent coal particles from settling. When the filter press chamber 31 is empty, the PLC control unit 61 controls the variable frequency speed control screw pump 26 to start, and transports the coal-water slurry in the storage tank to the filter press chamber 31 through the feed pipe 13. The electromagnetic flow meter 14 feeds back the flow data to ensure stable feeding. After feeding is completed, the hydraulic cylinder 51 pushes the movable filter plate 34 to perform single-stroke filter pressing, the hydraulic control valve group 52 adjusts the filter pressing pressure, and the filtered water is discharged through the outlet hole 35. After the filter press is completed, the hinge mechanism 42 drives the discharge outlet 41 to open, and the hydraulic cylinder 51 pushes the movable filter press plate 34 to push out the coal material, thus completing the discharge. After discharge, discharge outlet 41 is closed, and the device enters the next round of feed and filter press cycle.

[0042] In summary, this invention, by setting up a dual-compartment buffer storage tank and adopting a parallel alternating working mode, combined with a stirring device to prevent coal particle sedimentation, resolves the contradiction between the continuous generation of coal-water slurry and the intermittent operation of the filter press, ensuring the continuity of the filtration process. Furthermore, this invention employs a PLC control unit combined with a PID closed-loop control algorithm, along with a variable frequency speed-regulating screw pump and a hydraulic control system, to precisely control the filtration pressure, stroke, and feed flow rate. The pressure adjustment range is 0.6~1.2MPa, with rapid response, improving separation efficiency. The filter plates and screens of this invention are installed using an interlocking process, coupled with a top hinge mechanism, which facilitates disassembly, cleaning, and maintenance, reducing maintenance costs. The support system adopts a four-point box-type welded frame, equipped with rubber vibration damping pads and adjustable anchor bolts, effectively distributing the load, avoiding resonance, ensuring the stability of equipment operation, and extending service life. The feed hopper is equipped with an ultrasonic anti-clogging vibrator, and the conveying pipeline is equipped with a pneumatic butterfly valve and a check valve to prevent material blockage and backflow, further improving the reliability of the device operation.
