Description

Technical Field

[0001] This invention relates to the field of coal slime settling technology, specifically to a coal slime settling treatment device. Background Technology

[0002] In industrial processes such as coal mining and washing, a large amount of coal slurry containing coarse and fine coal particles is generated, using water as a carrier. If this coal slurry is discharged or reused directly without effective treatment, it will not only waste coal resources but also cause serious pollution to the ecological environment, including water bodies and soil. It will also affect the normal operation of subsequent production equipment. Therefore, efficient sedimentation and separation treatment of coal slurry is one of the key links in the green development and resource recycling of the coal industry.

[0003] Currently, the mainstream equipment for treating coal slurry water in the industry is mainly horizontal flow sedimentation tank. The core working principle of this type of equipment is based on static gravity sedimentation. After the coal slurry water to be treated enters the sedimentation tank through the inlet, it flows slowly in the horizontal direction in the tank. During this process, the coal slurry particles naturally sink downwards due to their own gravity and eventually settle at the bottom of the tank to form underflow. The clarified water is discharged from the outlet at the end of the tank, realizing the initial separation of coal slurry and water.

[0004] Current coal slime settling treatment devices typically handle coal slime water with varying particle sizes. Coarse coal slime particles, due to their greater gravity, can settle and separate in a short time at the front of the settling tank. However, fine coal slime particles have very little gravity and often carry surface charges, easily forming a stable colloidal suspension system. In the static environment of a horizontal flow settling tank, the driving force for conventional gravity settling is insufficient, resulting in a large number of fine coal slime particles suspended on the surface and in the shallow layer of the coal slime water. They are difficult to effectively capture and settle to the bottom of the tank, leading to low fine coal slime retention efficiency and difficulty in meeting effluent quality standards.

[0005] To address the above problems, a coal slime settling treatment device is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a coal slime settling treatment device. By using this device, the problem of low retention efficiency of fine coal slime, which has very low gravity, is difficult to effectively capture and settle to the bottom of the pool, is solved.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A coal slime settling treatment device includes a horizontal flow sedimentation tank. A lifting component is fixedly installed on one side of the horizontal flow sedimentation tank, and a fixed base is installed on one side of the lifting component. A driving component is fixedly installed inside the fixed base. Four electromagnetic components are installed at one end of the fixed base, and all four electromagnetic components are rotatably connected to the fixed base. An output component is installed on one side of the electromagnetic component and is electrically connected to the electromagnetic component. The output component is rotatably connected to the fixed base, and the driving component is drively connected to the output component. Four elastic components are installed at one end of the fixed base, and the four electromagnetic components are slidably connected to the four elastic components. A pressure plate is fixedly installed at one end of each elastic component.

[0008] Furthermore, the lifting component includes a support block and a frame fixed to one side of the support block. The support block is fixedly installed on both sides of the horizontal sedimentation tank. Screws are rotatably connected to both sides of the frame. A first motor is fixedly installed on one side of the frame, and the output end of the first motor is fixedly connected to one of the screws. Pulleys are fixedly installed on the surfaces of both screws, and the two pulleys are connected by belt drive.

[0009] Furthermore, the fixing base includes a disc and a fixing frame fixed to one side of the disc. Circular plates are installed around the fixing frame. Three support plates are installed at an angle on one side of the circular plates. A rotating disc is fixedly installed at one end of each of the three support plates. A rotating groove is opened inside the circular plate.

[0010] Furthermore, a horizontal plate is fixedly installed on the surface of the disc, and three positioning plates are fixedly installed on the surface of the horizontal plate. All three positioning plates are fixedly connected to the disc by bolts. Threaded plates are fixedly installed at both ends of the horizontal plate. The threaded plates are slidably connected to the frame and threadedly connected to the screw.

[0011] Furthermore, the driving component includes a second motor and a first gear fixed to the output end of the second motor. The second motor is fixedly connected to the fixed frame, and the first gear is rotatably connected to the fixed frame.

[0012] Furthermore, the electromagnetic component includes a ring frame and a ring coil fixed inside the ring frame. A limiting ring is fixedly installed on the surface of the ring frame, and the limiting ring is rotatably connected to the rotating groove. A roller is fixedly installed on the surface of the ring frame.

[0013] Furthermore, the output component includes a hollow tube and a high-frequency power supply fixed inside the hollow tube. The hollow tube is rotatably connected to the rotating disk. One end of the high-frequency power supply is connected to a wire, which passes through and connects to one side of the ring frame. The wire is electrically connected to the ring coil. A second gear is fixedly installed on the surface of the hollow tube, and the first gear meshes with the second gear.

[0014] Furthermore, the elastic element includes a vertical rod and a T-shaped rod fixed to one end of the vertical rod. The T-shaped rod is slidably connected to the fixing frame, and a spring is fixedly installed on the T-shaped rod, with one end of the spring fixedly connected to the inside of the fixing frame.

[0015] Furthermore, inclined grooves are provided on both sides of the vertical rod, and the rollers are in contact with the inclined grooves.

[0016] Furthermore, the surface of the pressure plate is provided with several conical holes.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By using the horizontal flow sedimentation principle of the horizontal flow sedimentation tank, foreign objects and large-diameter coal lumps in the coal slurry water are quickly intercepted at the bottom of the front end of the tank, thus preventing these impurities from entering the subsequent water tank and clogging the water pump from the source.

[0018] 2. By disrupting the double electric layer structure of fine coal slime particles and breaking the water molecule adsorption film through a high-frequency alternating electromagnetic field, the particles are transformed into a state awaiting agglomeration. The drive component drives the output component to rotate, which in turn drives the four electromagnetic components to rotate synchronously. Under the dual action of electric field force and mechanical stirring force, the fine coal slime particles in the state awaiting agglomeration are more likely to collide and adsorb with each other, and quickly aggregate to form flocs with larger particle size and stronger gravity, which greatly accelerates the settling speed.

[0019] 3. The pulsed flow field formed by the up-and-down movement of the pressure plate driven by electromagnetic components breaks the original laminar flow structure of the horizontal flow sedimentation tank, which can promote the rapid collision and adsorption of fine coal slime particles to form large-diameter flocs. Compared with the traditional horizontal flow sedimentation tank that only relies on gravity sedimentation, it accelerates the sedimentation and separation speed of fine coal slime.

[0020] 4. The pressure plate disturbs the middle layer of water to create convection, lifting the unagglomerated fine coal sludge in the middle layer to the surface strong electromagnetic zone for further treatment. This ensures that all fine coal sludge in the pool can be acted upon by electromagnetic fields or mechanical forces, effectively avoiding the problem of fine coal sludge failing to settle due to stagnation in stable laminar flow.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To address the technical problem of low retention efficiency of fine coal slime due to its extremely low weight, making it difficult to effectively capture and settle to the bottom of the pool, such as... Figures 1-9 As shown, the following preferred technical solutions are provided: like Figure 1 As shown, a coal slime settling treatment device includes a horizontal flow sedimentation tank 1, which serves as the basic treatment carrier for the entire device. Its core value lies in both pretreatment protection and foundation settling support. From a protection perspective, it utilizes the characteristics of horizontal flow sedimentation to intercept large-diameter coal particles such as stones in the coal slime water in advance, preventing these impurities from entering the subsequent water tank and clogging the water pump, reducing equipment failure frequency, lowering maintenance costs, and ensuring continuous and stable system operation. The device is characterized by a lifting component 2 fixedly installed on one side of the horizontal flow sedimentation tank 1, and a fixed seat 3 installed on the other side of the lifting component 2. The lifting component 2 is a key component for achieving precise adaptation and flexible adjustment of the device. On one hand, it can flexibly adjust the height of the fixed seat 3 according to the actual liquid level of the coal slime water in the horizontal flow sedimentation tank 1 and the stratification of fine coal slime suspension, with fine coal slime mostly concentrated in the surface and middle layers. A driving component 4 is fixedly installed inside the fixed seat 3, and four electromagnetic components 5 are installed at one end of the fixed seat 3, all of which are rotatably connected to the fixed seat 3. An output component 6 is installed on one side of each electromagnetic component 5, and the output component 6 is electrically connected to the electromagnetic component 5.

[0025] The drive unit 4 is the core power source of the device. On one hand, through its transmission connection with the output unit 6, it provides continuous and stable rotational power to the four electromagnetic components 5, driving them to stir the surface water, disrupt the hydration film of the fine coal slime particles, weaken the repulsive force between particles, and create mechanical conditions for the agglomeration of fine coal slime. On the other hand, the drive unit 4 can adjust its rotational speed and frequency according to the particle size and suspension state of the fine coal slime, achieving precise control of the stirring intensity. This avoids insufficient stirring due to excessively low speed, while also preventing the already formed flocs from being broken up due to excessively high speed, ensuring that the agglomeration efficiency of fine coal slime is improved and the separation effect is enhanced under optimal stirring parameters. The output unit 6 is rotatably connected to the fixed base 3, and the drive unit 4 is transmissionally connected to the output unit 6. Electromagnetic component 5 is a core functional component that breaks through the limitations of traditional gravity sedimentation separation and achieves efficient breaking and stabilization of fine coal slime. Its advantages are reflected in electromagnetic breaking and stabilization and synergistic linkage. In terms of electromagnetic breaking and stabilization, it forms an alternating electromagnetic field under the power supply of output component 6, which can force the redistribution of negative charges on the surface of fine coal slime particles, compress the double electric layer to weaken electrostatic repulsion, and at the same time break the water molecule adsorption film on the particle surface through induced eddy current, exposing the active adsorption surface, so that the fine coal slime changes from a stable suspended state to a state to be aggregated, solving the pain point of difficult sedimentation of fine coal slime in traditional sedimentation tanks and improving the separation effect. The four electromagnetic components 5 work simultaneously to form a uniform electromagnetic field and stirring area on the surface, avoiding the situation where fine coal slime is not treated in some areas and ensuring the uniformity of treatment.

[0026] Four elastic elements 7 are installed at one end of the fixed base 3. Four electromagnetic elements 5 are slidably connected to the four elastic elements 7, and a pressure plate 8 is fixedly installed at one end of each elastic element 7. The elastic element 7 is the power conversion component that realizes the pulse-like action of the pressure plate 8. On the one hand, when the electromagnetic element 5 rotates and pulls the elastic element 7 downward, it stores elastic potential energy. When the electromagnetic element 5 separates from the elastic element 7, the elastic potential energy is released, causing the pressure plate 8 to quickly reset, forming a pulse-like floating motion of downward movement and upward rebound. This provides power for the disturbance of the middle layer of water, assisting in the stabilization and sedimentation of fine coal slime. When the pressure plate 8 moves downward, it exerts local pressure on the middle layer of water, forming micro-convection. This can break the hydration film of fine coal slime colloidal particles, weaken the double electric layer repulsion, supplement the insufficient treatment of the electromagnetic component 5 in the middle layer, and further promote the fine coal slime to a state of unagglomeration. Secondly, its periodic up-and-down movement can break the laminar flow structure of the horizontal sedimentation tank 1 and form a pulsed flow field. When it moves upward, it drives the unagglomerated fine coal slime in the lower layer to return to the strong electromagnetic zone of the water surface for reprocessing. When it moves downward, it pushes the agglomerated flocs in the upper layer to settle to the bottom of the tank at an accelerated speed, reducing the retention and loss of fine coal slime.

[0027] First, relying on the horizontal flow sedimentation principle of the horizontal flow sedimentation tank 1, the coal slurry water is initially treated. After the coal slurry water to be treated enters the tank, it flows slowly in the horizontal direction. During the process, foreign objects and large-diameter coal lumps in the water settle quickly to the bottom of the front end of the tank due to their own weight, achieving early interception and effectively preventing foreign objects from clogging the water pump when the water tank is filled later. According to the actual liquid level and stratification of the coal slurry water in the horizontal flow sedimentation tank 1, fine coal slurry is usually mainly suspended in the surface and middle layers of water. By controlling the lifting component 2 to adjust the height of the fixed seat 3, the fixed seat 3 drives the four connected electromagnetic components 5 to move precisely to the surface water where the fine coal slurry is concentrated, while ensuring that the four elastic components 7 and the pressure plate 8 are stably in the middle layer of water.

[0028] Once the electromagnetic component 5 and the pressure plate 8 are in place, the drive component 4 is activated, and a stable current is continuously output to the electromagnetic component 5 through the output component 6. Under the influence of the current, each electromagnetic component 5 generates an alternating electromagnetic field around it. The high-frequency alternating magnetic field forces the negative charge on the surface of the fine coal slime particles to redistribute rapidly along the direction of the magnetic field. The double electric layer that originally uniformly wrapped the particles is squeezed and deformed, and the electrostatic repulsion between the particles is greatly reduced, creating a condition for particle aggregation. The electromagnetic field induces eddy currents inside the fine coal slime particles. The vibration generated by the eddy currents is transmitted to the water molecule adsorption film on the particle surface, breaking the adsorption force between the water film and the particles, causing the water film to fall off. At this time, the active surface of the particles... With the adsorption surface exposed, the fine coal slime changes from a stable suspended state to a state awaiting agglomeration, thus meeting the conditions for mutual adsorption. Subsequently, the drive component 4 drives the output component 6 to rotate, which in turn drives the four electromagnetic components 5 to rotate synchronously. The rotating electromagnetic components 5 directly drive the flow of the surrounding surface water, creating a slight stirring effect. This mechanical disturbance can further destroy the hydration film remaining on the surface of the fine coal slime particles, weaken the hydration repulsion and steric hindrance effect between particles, and make the fine coal slime particles in the state awaiting agglomeration more likely to collide and adsorb with each other under the dual action of electric field force and mechanical stirring force, quickly agglomerating to form flocs with larger particle size and stronger gravity, greatly accelerating the settling speed.

[0029] On the other hand, the rotation of the electromagnetic component 5 will cause the four elastic components 7 to stretch downwards synchronously, thereby pulling the pressure plate 8 downwards. When the pressure plate 8 moves downwards, it will exert local pressure on the middle layer of water, disturbing the water and forming micro-convective currents. The convective impact force can break the double electric layer structure of the fine coal slime colloidal particles in the middle layer, further weakening the suspension stability and causing them to become unagglomerate. The periodic up-and-down movement of the pressure plate 8 breaks the original laminar flow structure of the horizontal flow sedimentation tank 1, forming a pulsed flow field in the middle layer. When it moves upwards, it will drive the water below to flow upwards, lifting the unagglomerated fine coal slime particles in the lower layer to the surface strong electromagnetic zone, where they will be subjected to the electromagnetic field again and agglomerate. When it moves downwards, it will push the small flocs that have already formed above to flow downwards. This provides additional downward thrust, helping the flocs overcome the viscous resistance of the water and accelerate their settling to the bottom of the tank. The pulsed flow field continuously disturbs the middle layer of water, preventing fine coal slime particles from being trapped in a stable laminar flow for a long time. This ensures that all fine coal slime can be acted upon by electromagnetic fields or mechanical forces, improving the overall separation efficiency. Compared with traditional horizontal flow sedimentation tanks that rely solely on gravity settling, this device uses high-frequency alternating electromagnetic fields to rapidly aggregate fine coal slime. The synergistic effect of the up-and-down disturbance and agglomeration can improve the retention rate of fine coal slime. The electromagnetic field precisely disrupts the stable colloidal structure, while the mechanical force promotes particle collision and agglomeration. This dual effect causes the originally difficult-to-settle fine coal slime to form large-diameter flocs, improving the separation effect and effectively recovering coal resources.

[0030] like Figure 2 As shown, the lifting component 2 includes a support block 21 and a frame 22 fixed to one side of the support block 21. The support block 21 is fixedly installed on both sides of the horizontal flow sedimentation tank 1. The support block 21 is a basic fixed structure, which is firmly connected to the tank walls on both sides of the horizontal flow sedimentation tank 1 by bolts or welding, providing stable support for the frame 22 and ensuring that the entire lifting system does not shift or shake during operation. Screws 23 are rotatably connected to both sides of the frame 22. A first motor 24 is fixedly installed on one side of the frame 22, and the output end of the first motor 24 is fixedly connected to one of the screws 23. Pulleys 25 are fixedly installed on the surfaces of both screws 23, and the two pulleys 25 are connected by belt drive. When the height of the fixed base 3 needs to be adjusted, the first motor 24 fixed on one side of the frame 22 is started. The output shaft of the first motor 24 directly drives one of the screws 23 fixed to it to rotate. Since both screws 23 have pulleys 25 fixed on their surfaces and the two pulleys 25 are connected by a belt, the rotating screw 23 will drive the other screw 23 to rotate synchronously and at the same speed through the meshing of the pulleys 25 and the belt. At this time, the fixed base 3, which is connected to the two screws 23 by threaded engagement, will move linearly up and down along the axis of the screws 23 under the driving force of the rotation of the screws 23. By controlling the forward and reverse rotation of the first motor 24, the fixed base 3 can be raised or lowered.

[0031] like Figures 3-4As shown, the mounting base 3 includes a disc 31 and a mounting frame 32 fixed to one side of the disc 31. Circular plates 33 are installed around the mounting frame 32. Three support plates 34 are installed at an angle on one side of the circular plates 33. A rotating disk 35 is fixedly installed at one end of each support plate 34. The support plates 34 are rigid support links connecting the circular plates 33 and the rotating disk 35. Their inclined installation design has the dual value of structural reinforcement and power transmission assistance. From a structural reinforcement perspective, the three support plates 34 are evenly distributed along the circumference of the circular plates 33 and at an inclined angle, forming a stable structure similar to a triangular bracket. This significantly improves the connection strength between the circular plates 33 and the rotating disk 35, preventing the rotating disk 35 from shaking or displacing when rotating with the electromagnetic component 5, thus ensuring the overall structure's vibration resistance. A rotating groove 36 is provided inside the circular plate 33. The rotating groove 36 is a key guiding structure that ensures the stable rotation of the electromagnetic component 5, and its value lies in limiting guidance and sealing protection. First, the groove shape of the rotating trough 36 is precisely matched with the size of the rotating shaft of the electromagnetic component 5, which can limit the radial displacement of the rotating shaft and ensure that the electromagnetic component 5 rotates only along its own axis, avoiding the electromagnetic field position shift caused by the shaking of the rotating shaft, thereby ensuring the uniformity of electromagnetic field coverage in the fine coal slime treatment area.

[0032] A horizontal plate 311 is fixedly mounted on the surface of the disc 31. Three positioning plates 312 are fixedly mounted on the surface of the horizontal plate 311, and all three positioning plates 312 are fixedly connected to the disc 31 by bolts. The advantages of this method lie in the double-fixed reinforcement and convenient installation and adjustment. Threaded plates 313 are fixedly mounted at both ends of the horizontal plate 311. The threaded plates 313 are slidably connected to the frame 22 and threadedly connected to the screw 23. The internal threads of the threaded plates 313 are precisely matched with the surface threads of the screw 23, which can efficiently convert the rotational motion of the screw 23 into the linear lifting motion of the fixed seat 3, reducing... Minimal energy loss during transmission ensures rapid response in lifting and lowering actions. Simultaneously, the threaded transmission method provides self-locking, allowing the fixed seat 3 to remain stably stationary without additional locking components once it reaches the target height, preventing height deviation due to unexpected vibrations. For stable guidance, the sliding connection between the threaded plate 313 and the frame 22 provides guidance and restriction for the lifting and lowering of the fixed seat 3, preventing circumferential rotation as the screw 23 rotates. This ensures the fixed seat 3 remains horizontal during lifting and lowering, thereby guaranteeing the stability of the electromagnetic component 5 during rotation and the consistency of the electromagnetic field's effective area, preventing the deflection of the fixed seat 3 from affecting the fine coal slime treatment effect.

[0033] The drive component 4 includes a second motor 41 and a first gear 42 fixed to the output end of the second motor 41. The second motor 41 is fixedly connected to the fixed frame 32, and the first gear 42 is rotatably connected to the fixed frame 32. The rotatable connection design between the first gear 42 and the fixed frame 32 can provide a stable support point for the first gear 42, avoid transmission jamming due to radial shaking during meshing, further ensure the continuity and stability of power transmission, and provide a reliable guarantee for the coordinated mechanical action of the entire device.

[0034] like Figures 5-6 As shown, the electromagnetic component 5 includes a ring frame 51 and a ring coil 52 fixed inside the ring frame 51. The ring structure allows the magnetic field to spread radially in a ring, covering a wider range and simultaneously acting on the fine coal slime area around the ring frame 51, avoiding magnetic field blind spots. Moreover, the magnetic field response speed of the ring coil 52 is fast after being energized, and it can reach a stable magnetic field strength within a few seconds. The breaking and stabilizing operation can be started without preheating, which greatly improves the processing efficiency. A limit ring 53 is fixedly installed on the surface of the ring frame 51. The limit ring 53 is rotatably connected to the rotating groove 36. The outer diameter of the limit ring 53 is precisely matched with the inner diameter of the rotating groove 36 of the fixed seat 3. After being embedded in the rotating groove 36, it can limit the radial displacement and axial movement of the ring frame 51, ensuring that the ring frame 51 always rotates stably around the preset axis, avoiding the misalignment of the electromagnetic field coverage area due to rotational deviation, thereby preventing the situation where local fine coal slime is not treated, ensuring the uniformity of breaking and stabilizing. A roller 54 is fixedly installed on the surface of the ring frame 51.

[0035] Output component 6 includes a hollow tube 61 and a high-frequency power supply 62 fixed inside the hollow tube 61. The hollow tube 61 is rotatably connected to the rotating disk 35. One end of the high-frequency power supply 62 is connected to a wire 63. The internal cavity of the hollow tube 61 provides a safe and independent channel for the wire 63. This allows mechanical transmission and electrical transmission to be realized on the same shaft, achieving a high degree of structural integration. It avoids the entanglement and interference between the power line and mechanical components, significantly improving the reliability of the device operation. The wire 63 runs through and is connected to one side of the ring frame 51, and the wire 63 is electrically connected to the ring coil 52. The high-frequency power supply 62 can output a stable current with adjustable frequency and amplitude. By precisely controlling the current frequency, it can be matched with the charge characteristics and Brownian motion frequency of the fine coal slime particles, thereby efficiently compressing their double layer and destroying the hydration film. This targeted treatment method has higher destabilization efficiency and energy utilization rate than traditional static or low-frequency electric fields. A second gear 64 is fixedly installed on the surface of the hollow tube 61, and the first gear 42 is meshed with the second gear 64. When the second motor 41 drives the first gear 42 to rotate, the first gear 42 can drive the second gear 64 to rotate, thereby driving the hollow tube 61 and the ring frame 51 to rotate, causing the surrounding surface water to flow and forming a slight stirring effect.

[0036] To address the technical problem of fine coal slime particles easily remaining in the middle layer, such as... Figures 7-9 As shown, the following preferred technical solutions are provided: The elastic element 7 includes a vertical rod 71 and a T-shaped rod 72 fixed to one end of the vertical rod 71. The vertical rod 71 is made of high-strength material to ensure long service life and stability. The T-shaped rod 72 is slidably connected to the fixed frame 32. A spring 73 is fixedly installed on the T-shaped rod 72. The slidable connection between the T-shaped rod 72 and the fixed frame 32 provides precise vertical movement guidance for the entire spring 73, ensuring that the extension and contraction of the spring 73 and the movement of the vertical rod 71 always remain in the vertical direction, avoiding lateral deviation. One end of the spring 73 is fixedly connected to the inside of the fixed frame 32. The spring 73 is stretched to store elastic potential energy. When the spring 73 releases its potential energy, it drives the pressure plate 8 to quickly reset, cleverly converting rotational motion into reciprocating linear motion. The spring 73 and the T-shaped rod 72 provide stable and efficient pulse power for the pressure plate 8, which is one of the key links to achieve efficient breaking and settling of fine coal slime.

[0037] Inclined grooves 711 are provided on both sides of the vertical rod 71. The roller 54 contacts the inclined grooves 711. Initially, the roller 54 does not contact the inclined grooves 711. When the ring frame 51 rotates, it can drive the roller 54 to make synchronous circular motion. Since the inclined grooves 711 on both sides of the vertical rod 71 are designed with inclined slopes, when the roller 54 rotates with the ring frame 51 and rolls along the inclined grooves 711, the inclined surface of the inclined grooves 711 will generate a radial guiding force on the roller 54. The circular motion of the roller 54 The limiting structure of the inclined groove 711 is converted into linear motion along the inclined plane. At the same time, this motion pushes the vertical rod 71 to overcome the elastic force of the spring 73 through the reaction force of the inclined plane and moves downward along the vertical direction of the fixed frame 32. At this time, the pressure plate 8, which is fixedly connected to the lower end of the vertical rod 71, will move downward synchronously with the vertical rod 71. When the roller 54 rotates with the ring frame 51 to the end of the inclined groove 711, the contact relationship between the roller 54 and the inclined groove 711 is released, and the downward thrust on the vertical rod 71 disappears. At this time, the stretched spring 73 will quickly release the stored elastic potential energy, generate an upward restoring force, and push the vertical rod 71, which is fixedly connected to the T-shaped rod 72, to bounce upward in the vertical direction until it returns to its initial position. At the same time, the vertical rod 71 drives the pressure plate 8 to move upward synchronously, and finally form a stable pulsed floating in the middle layer of coal slurry water, providing continuous mechanical disturbance for the destabilization and sedimentation of fine coal slurry. The pulsed floating of the pressure plate 8 directly acts on the area where fine coal slurry is easy to retain in the middle layer of coal slurry water. When it moves downward, it squeezes the water to form a small convection, breaks the hydration film of colloidal particles, and when it bounces upward, it drives the lower layer of unagglomerated fine coal slurry back to the strong electromagnetic zone of the water surface, while pushing the upper layer of flocs to settle faster.

[0038] The pressure plate 8 has several conical holes 81 running through its surface. When the pressure plate 8 moves downward, the water in the middle layer is squeezed and quickly passes through the conical holes 81, achieving a structure with a small inlet and a large outlet. This causes the water flow to form an accelerated jet within the hole. After the jet impacts the water below, it forms a local vortex. When it rebounds upward, the water below flows in the opposite direction through the conical holes 81 with a large inlet and a small outlet, forming a reverse jet and vortex again. This can more deeply break the stable hydration film around the fine coal slime particles and weaken the double electric layer repulsion. It is especially effective in breaking down the small colloidal particles dispersed in the middle layer, causing more fine coal slime to change from a stable suspended state to a state awaiting aggregation. The water flow that accelerates through the conical holes 81 will drive the surrounding small fine coal slime particles to move synchronously. The particles will have relative motion due to changes in flow velocity within the channel and in the jet area, increasing the probability of collision. At the same time, the inner wall of the conical holes 81 can have a slight adsorption and guiding effect on the particles, guiding small particles to gather towards the center of the channel and promoting the formation of small flocs.
