[0053] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] Reference Figure 1 to Figure 8 , which is an embodiment of the utility model, proposes a coal slime slurrying, soaking, flushing and softening device, including: a slurrying tank 1, having a working groove 101; a hopper 2, which is slidably arranged in the working groove 101, the hopper 2 has a containing space 203, and the outer wall of the hopper 2 has a plurality of through grooves 205, and the containing space 203 is connected with the working groove 101 through the through grooves 205; a plurality of flushing members 4, which are arranged on the hopper 2 at intervals, and the flushing member 4 has a working end, and the working end faces the inner side of the containing space 203; a lifting mechanism 3, which is arranged on the slurrying tank 1, and the hopper 2 is arranged on the lifting mechanism 3, and the lifting mechanism 3 is used to drive the hopper 2 to slide along the working groove 101.

[0055] In the above scheme, a coal slime slurrying, soaking, flushing and softening device is designed to overcome the problem of uneven coal slime slurrying in the prior art, improve the efficiency and quality of coal slime raw material processing, and meet the high standards of coal mine flotation system for raw materials. The slurrying pool 1 of this embodiment is made of corrosion-resistant stainless steel material, and its working tank 101 is designed to be rectangular with moderate depth and volume to ensure that the coal slime raw material can be fully soaked and stirred therein. The bottom of the working tank 101 is provided with an inclined design to facilitate subsequent drainage and impurity removal operations. The hopper 2 is made of lightweight and high-strength material, and its shape fits the inner wall of the working tank 101 and slides freely. The accommodating space 203 of the hopper 2 is large enough to load a certain amount of coal slime raw material. Several through grooves 205 evenly distributed on the outer wall of the hopper 2 not only ensure that the coal slime is fully mixed with the water in the working tank 101, but also promote the natural flow of the coal slime in the hopper 2 during the lifting process, thereby improving the soaking effect. When the hopper 2 slides up and out of the slurry mixing tank 1 under the action of the lifting mechanism 3, the flushing member 4 flushes the coal slime, which not only softens and dissolves the coal slime, but also effectively removes impurities on the surface and inside of the coal slime, thereby improving the purity of the coal slime. The lifting mechanism 3 is driven by a motor and connected to the hopper 2 by a chain or a wire rope, and can accurately control the up and down sliding of the hopper 2 in the working tank 101. During the soaking stage, the hopper 2 sinks to the bottom of the working tank 101, and the coal slime is fully mixed with water. Subsequently, the lifting mechanism 3 is started, driving the hopper 2 to rise slowly. As the hopper 2 rises, the flushing member 4 continuously flushes the coal slime. At the same time, the through groove 205 on the outer wall of the hopper 2 allows excess water and impurities to flow out naturally during the rising process of the hopper 2, thereby achieving the softening and purification of the coal slime.

[0056] Operation process: First, add the coal slime raw material into the hopper 2, and then sink the hopper 2 to the bottom of the working tank 101 filled with water and soak for a certain period of time. After that, start the lifting mechanism 3, and the hopper 2 gradually rises. During this period, the flushing part 4 flushes the coal slime, and at the same time, the through groove 205 on the outer wall of the hopper 2 helps to discharge excess water and impurities. After the hopper 2 is fully lifted, the obtained coal slime slurry is uniform and pure, and can be directly pumped to the pre-flotation slurry pretreatment machine or surface modification machine, thereby improving the subsequent flotation efficiency and coal recovery rate. The coal slime slurry immersion flushing softening device of this embodiment realizes the efficient softening of coal slime and the effective removal of impurities through its unique structural design and operation process, solves the problems existing in the prior art, and improves the quality and efficiency of coal slime treatment.

[0057] Furthermore, the working groove 101 has a protrusion 102 inside, and the hopper 2 is slidably set on the protrusion 102. The hopper 2 includes: a box body 201, having a feed port 2011, and the box body 201 has a first space 2031; a basket 202, which is arranged below the box body 201, and the basket 202 has a second space 2032, and the first space 2031 and the second space 2032 are combined to form a accommodating space 203; a through groove 205 is opened on the circumferential side wall and bottom surface of the basket 202; a slide rail 204 is arranged on the outer wall of the basket 202, and the slide rail 204 is slidably set on the protrusion 102.

[0058] In the above scheme, a protrusion 102 structure is added inside the working trough 101. The protrusion 102 is arranged longitudinally along the inner wall of the working trough 101, providing a stable support platform for the sliding track of the hopper 2, and at the same time increasing the hydrodynamic performance inside the working trough 101, promoting the mixing of water and coal slime. The hopper 2 is designed to be composed of two parts, namely a box body 201 and a basket 202. The box body 201 is located above the basket 202 and is provided with a feed port 2011 to facilitate the loading of coal slime raw materials. The box body 201 forms a first space 2031 inside, which is used to initially accommodate coal slime and install the flushing member 4. The basket 202 is located below the box body 201 and is designed with a second space 2032, which is interconnected with the first space 2031 of the box body 201 to form a holding space 203 together. This design not only ensures sufficient accommodation of coal slime, but also facilitates the movement and hydration of coal slime inside the hopper 2. The circumferential side walls and bottom surface of the basket 202 are provided with through grooves 205. Compared with the through grooves 205 that are only provided on the outer wall of the hopper 2, they are more evenly distributed around and on the bottom of the basket 202, which not only increases the surface area of ​​contact between water and coal slime, but also improves the uniformity and flushing efficiency of water flow through the hopper 2, which helps to soften the coal slime more thoroughly and remove impurities. Slide rails 204 are installed on the outer wall of the basket 202. These slide rails 204 match the protrusions 102 inside the working tank 101, ensuring the stability and stability of the hopper 2 (including the box body 201 and the basket 202) when sliding up and down in the working tank 101, reducing friction loss, facilitating operation and improving the durability of the system. Secondly, the structure of the slide rails 204 and the protrusions can also separate a distance between the basket 202 and the inner wall of the working tank 101, so that the through grooves 205 on the side wall of the basket 202 are connected to the working tank 101. The coal slime slurry immersion flushing and softening device of this embodiment realizes more precise adjustment in the structure of the working tank 101 and the hopper 2, effectively improving the efficiency and quality of coal slime treatment. The two-stage design of the hopper 2 and the circumferential and bottom through grooves 205 on the basket 202, combined with the smooth sliding mechanism of the slide rail 204, not only enhance the softening of coal slime and the discharge of impurities, but also simplify the equipment maintenance and operation process.

[0059] Furthermore, the bottom surface of the basket 202 is a slope 9, which is inclined along the direction from the feed port 2011 to the slurry mixing tank 1. The hopper 2 also includes: a step block 7, which has a plurality of step blocks 7, and the plurality of step blocks 7 are arranged on the slope 9 at intervals, and the plurality of step blocks 7 are located in the accommodating space 203.

[0060] In the above scheme, the bottom surface of the basket 202 is designed as a slope 9 structure, and the slope 9 is inclined from the feed port 2011 to the far end of the slurry mixing tank 1. This design uses the principle of gravity to enable the slurry mixed with coal slime and water to flow downward more smoothly during the lifting process of the hopper 2, reducing blockage and retention, while accelerating the natural emptying of the internal liquid and the sedimentation of impurities, and improving the cleaning efficiency. On the slope 9 of the basket 202, a number of step blocks 7 are arranged at intervals, and these step blocks 7 are also located inside the accommodating space 203. The design of the step blocks 7 is intended to further optimize the dynamic distribution and flow pattern of the coal slime in the basket 202. The setting of the step blocks 7 can form a series of small steps. When the coal slime passes between these steps, it is blocked and redistributed by the steps, which promotes the uniformity of the mixing of coal slime and water. At the same time, the gaps between the step blocks 7 become small water flow channels, which help to carry fine impurities and excess water out, thereby achieving more efficient softening and purification of coal slime during the lifting process.

[0061] Operation process: When the hopper 2 moves upward with the lifting mechanism 3, the coal slime in the basket 202 can not only be effectively flushed and softened under the combined action of the inclined surface 9 and the step block 7, but also can slide naturally through the channel and inclined surface 9 formed by the step block 7, so that the coal slime slurry is more uniform and the impurities are effectively separated. The combination of the inclined surface 9 design and the step block 7 forms a dynamic self-cleaning system inside the entire hopper 2, reducing the need for manual intervention and improving work efficiency. Through the above design, the innovation of the coal slime slurry immersion flushing and softening device in the basket 202 structure of this embodiment, especially the design of the inclined surface 9 and the step block 7, greatly improves the treatment effect of the coal slime, not only accelerates the softening and mixing process of the coal slime, but also optimizes the removal efficiency of impurities, prepares a more uniform and pure coal slime slurry for the subsequent coal slime flotation, and thus improves the efficiency and product quality of the entire flotation system.

[0062] Furthermore, it also includes: a mounting plate 5, which is arranged in the first space 2031, and the mounting plate 5 has a plurality of mounting holes 501, and a flushing component 4 is arranged in each mounting hole 501; the flushing component 4 is a high-pressure water gun, and the high-pressure water gun is connected to an external water source.

[0063] In the above scheme, a mounting plate 5 is added in the first space 2031 of the hopper 2. The mounting plate 5 is located at the top of the box body 201 or near the top, and fits tightly with the internal space of the hopper 2 to ensure stability. A number of mounting holes 501 are designed on the mounting plate 5. These mounting holes 501 are evenly distributed, and are intended to accurately place the flushing member 4, so as to achieve efficient flushing and softening of the coal slime. A high-pressure water gun is set in each mounting hole 501 as a flushing member 4. The high-pressure water gun is connected to the external water source through a water pipe, and can provide a continuous and strong water flow to deeply flush the coal slime. The high-pressure water gun can more effectively penetrate the coal slime layer, loosen the coal slime structure, promote the full mixing of water and coal powder, and can effectively flush away impurities on the surface and inside of the coal slime, thereby improving the purity of the coal slime slurry. Water supply system: The external water source connected to the high-pressure water gun needs to be equipped with a booster pump and a flow control device to ensure that a stable and adjustable high-pressure water flow can be provided. By adjusting the output pressure and water flow of the pump, the needs of different coal slime characteristics can be met, the flushing intensity can be flexibly adjusted, and the best softening and cleaning effects can be achieved.

[0064] Operation process: At the beginning of the work, the coal slime raw material is first added to the hopper 2. With the action of the lifting mechanism 3, the hopper 2 slowly rises, and the high-pressure water gun on the mounting plate 5 releases high-pressure water flow to strongly impact and flush the coal slime. At the same time, the coal slime continuously rolls and flows under the action of the inclined surface 9 of the basket 202 and the step block 7, making the flushing effect of the water gun more comprehensive and in-depth. Finally, the impurities in the coal slime are effectively separated, and the coal slime slurry becomes uniform and fine, and can be transported to the next processing link when ready.

[0065] Furthermore, the lifting mechanism 3 includes: a bracket 301, which is arranged on the slurry mixing tank 1, and the bracket 301 has a placement area 3011; a driving member 302, which is arranged on the placement area 3011, and the driving member 302 has a driving end; a pull rope, one end of which is arranged on the driving end, and the other end is arranged on the box 201, and the driving member 302 drives the pull rope to drive the box 201 to move.

[0066] In the above scheme, the support component of the lifting mechanism 3 is a bracket 301, which is firmly mounted on the top edge or side of the slurry mixing tank 1 to ensure the stability of the entire lifting mechanism 3. The bracket 301 is designed with a special placement area 3011, which is used to carry the driver 302 and other transmission components, while ensuring their correct alignment and stable operation. The driver 302 is located in the placement area 3011, and usually uses an electric motor or a hydraulic cylinder as a power source, with sufficient torque and speed adjustment capabilities to adapt to the different speed requirements of the hopper 2 lifting and lowering. The driving end of the driver 302 is designed with a connection structure, such as a gear, a turntable or a direct drive shaft, to facilitate the connection with the transmission component (pull rope). The pull rope is used as a power transmission medium, one end of which is fixed to the driving end of the driver 302, and the other end is fixed to an appropriate position of the hopper 2 box 201. The pull rope material needs to be selected from high-strength, wear-resistant, and corrosion-resistant materials, such as high-strength nylon rope or special steel wire rope, to ensure reliability and safety in long-term use. When the driving member 302 is started and its driving end rotates or retracts, power is transmitted to the hopper 2 through the pull rope, so that the hopper 2 moves up and down.

[0067] The lifting mechanism 3 will also be equipped with necessary safety devices, such as limit switches, overload protection and emergency stop buttons, to ensure that the operation can be stopped immediately under abnormal circumstances to protect the safety of equipment and operators. At the same time, through the control system, the operator can adjust the operating speed and stroke of the driving member 302 to adapt to different working conditions and coal slime processing requirements. Through the above design, the lifting mechanism 3 of this embodiment not only ensures the smooth and precise movement of the hopper 2 in the slurry mixing tank 1, but also realizes the effective transmission of power and the flexibility of operation through the reasonable design of the driving member 302 and the pull rope transmission, thereby improving the overall efficiency and safety of the coal slime slurry mixing, soaking, flushing and softening device.

[0068] Furthermore, the driving member 302 includes: a driver 3021, the driving end of which is located on the driver 3021; ​​a roller 3022, which is rotatably arranged on the bracket 301, the driving end is transmission-connected to the roller 3022, and the pull rope is wound around the roller 3022; a fixed pulley 3023, which is arranged on the bracket 301, the pull rope is overlapped on the fixed pulley 3023, and the fixed pulley 3023 is used to guide the fixed pulley 3023.

[0069] In the above scheme, the driver 3021 is used as the core power source of the lifting mechanism 3, and an electric motor is usually selected and installed in the placement area 3011 of the bracket 301. Its driving end is connected to the roller 3022 through a precise transmission mechanism (such as a gear set or a pulley) to ensure efficient power transmission. The roller 3022 is designed to be made of highly wear-resistant material, which can withstand the continuous friction of the pull rope, and multiple turns of the pull rope are wound on the roller 3022. When the driver 3021 is started, the roller 3022 rotates accordingly, and the pull rope is wound or released on the roller 3022, thereby pulling the hopper 2 up and down. One or more fixed pulleys 3023 are also provided on the bracket 301. The function of these fixed pulleys 3023 is to guide the pull rope, ensure that the pull rope runs along a predetermined trajectory during the movement, and avoid the pull rope from being entangled or excessively worn. The fixed pulley 3023 is usually made of a material with a low friction coefficient to reduce the running resistance of the pull rope and improve efficiency. After the pull rope comes out of the roller 3022, it is guided by the fixed pulley 3023 and then connected to the hopper 2 box 201. This design ensures the stability of the movement trajectory of the pull rope, reduces deviation and slippage, and improves the stability of the entire system.

[0070] In order to ensure the balance and stability of the hopper 2 during the lifting and lowering process, it is possible to consider adding a counterweight or spring compensation device to the design to balance the deadweight and load changes of the hopper 2, reduce the burden of the driver 3021, and improve the operating efficiency. At the same time, by adjusting the control unit of the driver 3021, the operator can adjust the lifting speed and stroke as needed to adapt to different operating conditions. Through the above design, the drive assembly in this embodiment not only realizes the efficient and accurate transmission of power, but also ensures the smoothness and guidance of the rope movement through the combination of the roller 3022 and the fixed pulley 3023, thereby improving the stability and safety of the entire lifting mechanism 3. Such a design optimizes the automation level of the coal slime slurry immersion flushing and softening device, and further improves the work efficiency and maintenance convenience.

[0071] Further, it also includes: a push plate 10, which is slidably arranged on the inclined surface 9, and the push plate 10 is located outside the basket 202; a plurality of vertical rods 6, which are arranged on the push plate 10 at intervals, and each vertical rod 6 extends into the second space 2032 through the through groove 205 of the inclined surface 9; a first connecting belt 12, one end of which is arranged on the side wall of the working groove 101, and the other end is arranged on the push plate 10, after the basket 202 moves up, the first connecting belt 12 pulls the push plate 10 to slide along the inclined surface 9 to one side; a second connecting belt 13, one end of which is arranged on the bottom surface of the working groove 101, and the other end is arranged on the push plate 10; after the basket 202 moves down, the second connecting belt 13 pulls the push plate 10 to slide along the inclined surface 9 to the other side. Further, it also includes: a track 8, which is arranged on the inclined surface 9, and the push plate 10 is slidably arranged in the track 8. It also includes: a limiting column 11, which is arranged in the working groove 101, and the limiting column 11 is located directly below the lowest point of the inclined surface 9. The first connecting belt 12 is arranged on the bottom surface of the working groove 101 after bypassing the limiting column 11.

[0072] In the above scheme, a slidable push plate 10 is added to the inclined surface 9 outside the basket 202. The push plate 10 is designed to be a light but sufficiently strong material to ensure smooth sliding on the inclined surface 9 while being able to withstand slight pressure from the coal slime. The position of the push plate 10 fits the inclined surface 9 at the bottom of the basket 202. A number of vertical rods 6 on the push plate 10 pass through the through groove 205 of the inclined surface 9 and penetrate into the second space 2032 of the basket 202. When the push plate 10 moves, the vertical rods 6 can stir the coal slime in the basket 202. When the basket 202 moves upward, the push plate 10 slides along the inclined surface 9 to the side close to the working groove 101 through the pulling of the first connecting belt 12. This action causes the coal slime to roll further inside the basket 202, accelerating the mixing of the coal slime and water and the shedding of impurities. When the lifting basket 202 moves downward, the bottom of the lifting basket 202 presses down the second connecting belt 13, so that the second connecting belt 13 drives the push plate 10 to slide along the inclined surface 9 toward the other side of the inclined surface 9. This process pushes the coal slime to move again, which helps the moisture and fine impurities in the coal slime to flow out along the inclined surface 9, thereby achieving further purification of the coal slime.

[0073] Operation effect: Through the coordinated work of the push plate 10 and the connecting belt, when the basket 202 moves up and down, the coal slime is not only stirred by the step block 7, but also pushed by the push plate 10, so that the moisture and impurities inside the coal slime are effectively separated, and the uniformity and purity of the coal slime slurry are improved. The sliding design of the push plate 10, especially through the guidance of the vertical rod 6, ensures the stability of the operation, reduces the mechanical damage to the coal slime during the treatment process, and improves the overall treatment efficiency. This embodiment further improves the dynamic treatment process of the coal slime inside the basket 202 through the introduction of the push plate 10 and the connecting belt, which not only strengthens the mixing and softening of the coal slime, but also optimizes the discharge mechanism of impurities, making the entire coal slime slurry preparation process more efficient and clean, and providing a higher quality coal slime slurry for the subsequent flotation step.

[0074] Furthermore, the basket 202 has a debris outlet 2021, which is located on the side wall of the basket 202 near the lowest position of the inclined surface 9, and also includes: a door panel 2022, the door panel 2022 has a filter slot 2023, and the door panel 2022 is hinged to the side wall of the basket 202.

[0075] In the above scheme, an impurity outlet 2021 is provided on the side wall of the basket 202 near the lowest position of the inclined surface 9, and this position is the end of the flow of the coal slime slurry and the natural deposition of impurities. The design size and position of the impurity outlet 2021 ensure that fine impurities and excess water can be discharged smoothly without affecting the flow of the coal slime, thereby reducing the risk of blockage inside the basket 202. The filter groove 2023 of the door panel 2022 is similar in structure to the through groove 205. The door panel 2022 is connected to the side wall of the basket 202 by a hinge, and can be flexibly opened and closed, which is convenient for regular cleaning and maintenance. Under normal working conditions, the door panel 2022 is closed to keep the inside of the basket 202 sealed, ensuring that the coal slime treatment process is not disturbed by the outside world.

[0076] Operation process: During the slurry mixing process, with the lifting and lowering of the basket 202, the pushing of the push plate 10 and the flushing of the high-pressure water gun, the slurry is continuously mixed, softened and the impurities are loosened. Under the flow of the slurry and the action of gravity, the loosened impurities naturally gather at the bottom of the basket 202, and finally reach the impurity outlet 2021 through the guidance of the inclined surface 9 and the step block 7. When it is necessary to discharge impurities, the basket 202 moves up to the highest position, and the operator opens the door panel 2022. The impurities are filtered by the filter tank 2023, and the pure water and fine impurities are discharged through the filter tank 2023 of the door panel 2022, while the large particles of impurities are retained on the door panel 2022 for easy cleaning. After cleaning, close the door panel 2022, the basket 202 returns to the working state, and the slurry treatment continues. Through this design, the impurity outlet 2021 and the door panel 2022 of the basket 202 not only provide an efficient way to discharge impurities, but also realize the preliminary screening of impurities through the filter tank 2023, further purify the coal slime slurry, improve the processing effect and efficiency of the entire coal slime slurry mixing system, and also simplify the subsequent maintenance operations.
