[0002] Coal slime is a byproduct of coal washing and processing, characterized by fine particle size, high moisture content, and high viscosity. Its efficient separation and recycling are crucial for improving resource utilization and reducing environmental pollution. Depending on different processing requirements and technological conditions, coal slime separation systems vary significantly in structural design, separation efficiency, and adaptability. Coal slime separation equipment is an important device primarily used in the coal washing field; its overall structure typically needs to balance ease of operation and stability of separation performance, with materials and technologies continuously optimized and upgraded to meet industry demands. However, in the practical application of existing coal slime separation systems, traditional equipment often suffers from insufficient modularity, leading to complex maintenance and limited operational efficiency.

[0003] Chinese patent CN20192135874U discloses a device for separating coal slime, including a feeding device, a separation chamber, a vibrating screen mechanism, and a dewatering unit.

This device can achieve preliminary classification and dewatering of coal slime, has a high degree of functional integration, and can meet certain production needs. The multi-stage screening design can effectively improve separation accuracy and reduce energy consumption in subsequent processing.

[0004] However, in the process of conceiving and implementing the above application, the inventors discovered that in actual use, the disclosed solution has weak independence between the functional modules, resulting in insufficient flexibility of the equipment in dealing with different processing scales or process requirements. Furthermore, the replacement and maintenance of some components require a long downtime, which affects the overall operating efficiency and economic benefits. Utility Model Content

[0007] The rotating shaft has its upper part rotatably connected to the separation component and extends out of the separation component. Its lower side wall is symmetrically provided with guide rails, which are engaged in the transmission sleeve, and the transmission sleeve is located in the adjustment cavity.

[0008] Two sets of drive arms are centrally symmetrically arranged on the outer wall of the transmission sleeve.

Two sets of locking pins are symmetrically arranged on the outer wall of the push block. A compression spring is sleeved on the locking pin, and the compression spring is located between the push block and the inner wall of the adjustment cavity.

[0009] Optionally, the outer wall of the separation component is provided with several diversion plates, and the top of the mounting frame is symmetrically provided with two sets of guide cylinders. Each set of guide cylinders is provided with a support column at its top, and the upper end of the support column is fixedly connected to the top of the separation component. The lower end of the support column is located inside the guide cylinder and is connected to a limit block. The bottom of the limit block is provided with a reset spring.

[0010] Optionally, it also includes an adjustment mechanism disposed between the base frame and the separation assembly, the adjustment mechanism comprising:

[0011] Two sets of sliding grooves are symmetrically opened in the top of the mounting frame. Each set of sliding grooves is slidably connected to a sliding block. The upper end of the sliding block is movably connected to the inner top of the separation component through a second connecting rod. A push-pull rod is connected to one side of the inner wall of the sliding block. A first hydraulic chamber is provided on one side of the push-pull rod. A first piston is slidably connected in the first hydraulic chamber. One end of the push-pull rod extends into the hydraulic chamber and is connected to the first piston. One end of the first hydraulic chamber is connected to a first hydraulic pipe.

[0012] Optionally, the lower end of the first hydraulic pipe passes through the support platform and the fixed plate in sequence and is connected to a second hydraulic pipe. One end of the second hydraulic pipe is connected to a second hydraulic chamber, which is located inside the base frame. A buffer spring is provided inside the second hydraulic chamber.

[0019] The technical advantages of this invention are as follows: By rotating the operating handle, in conjunction with the guide rail driving the transmission sleeve, the drive arm pulls the first connecting rod, which in turn moves the push block, thereby pulling the locking pin out of the locking hole. This separates the fixing plate and the base frame. During installation, after repeating the above steps, inserting the fixing plate into the positioning groove and releasing the applied force allows the locking pin to reset under the action of the compression spring, allowing it to insert into the locking hole, thus completing the installation.

The application of sealing rings and seals ensures the sealing of the hydraulic system, preventing liquid leakage from affecting equipment performance.

[0021] In summary, this utility model, through the combination of modular design and multi-stage adjustment mechanism, solves the problems of insufficient modularity, complex maintenance, and limited operating efficiency in existing coal slime separation systems, significantly improving the ease of operation and stability of separation effect, and has high practical value and promising prospects for promotion.

Detailed Implementation

[0025] This utility model relates to a modular high-efficiency coal slime separation system, the specific implementation of which is combined with Figures 1 to 2 And the accompanying reference numerals are explained in detail. For example... Figure 1 As shown, the overall structure includes a base frame 1, a support platform 2, a separation component 3, and an adjustment mechanism. The support platform 2 is located on the top of the base frame 1. A fixing plate and a mounting bracket are fixed to the bottom and top of the support platform 2, respectively. The fixing plate is fitted into a positioning groove on the top of the base frame 1. An adjustment cavity is formed within the fixing plate. The separation component 3 is located above the mounting bracket. The upper part of the rotating shaft 4 is rotatably connected to the separation component 3 and extends beyond it. Guide rails are symmetrically arranged on its lower sidewall, and these guide rails are engaged within a transmission sleeve 5, which is located within the adjustment cavity. Two sets of drive arms 6 are symmetrically arranged at the center of the outer wall of the transmission sleeve 5. One end of each drive arm 6 is hinged to a first connecting rod, and one end of the first connecting rod is hinged to a push block 7. Two sets of locking pins 8 are symmetrically arranged on the outer wall of the push block 7. A compression spring is fitted onto each locking pin 8, located between the push block 7 and the inner wall of the adjustment cavity. Locking holes for inserting the locking pins 8 are formed on the inner sidewall of the positioning groove.

[0026] like Figure 2 As shown, the rotating shaft 4 is rotatably connected to the fixed plate and the separation assembly 3 via ball bearings, and an operating handle is provided at the upper end of the rotating shaft 4. When the operating handle is rotated, the rotating shaft 4 rotates accordingly, and the guide rail on it drives the transmission sleeve 5 to rotate synchronously. The rotation of the transmission sleeve 5 causes the drive arm 6 to move, and the drive arm 6 pulls the first connecting rod to move. The first connecting rod pushes the push block 7 to move along the adjustment cavity, and the movement of the push block 7 further drives the locking pin 8 to move out of the locking hole, thereby realizing the disassembly between the fixed plate and the base frame 1. During the installation process, after the fixed plate is inserted into the positioning groove, the applied force is released, the compressed spring returns to its deformation, and pushes the locking pin 8 into the locking hole, completing the locking of the fixed plate and the base frame 1. This design realizes the modular quick disassembly and assembly function, which facilitates the maintenance and replacement of the equipment.

[0027] Several flow dividers 13 are installed on the outer wall of the separation assembly 3. The cross-section of the flow dividers 13 is arc-shaped to optimize the flow path of coal slime within the separation assembly 3 and reduce clogging. Two sets of guide cylinders 14 are symmetrically arranged on the top of the mounting frame. Each set of guide cylinders 14 has a support column 15 at its top. The upper end of the support column 15 is fixedly connected to the inner top of the separation assembly 3, and the lower end of the support column 15 is located inside the guide cylinder 14 and connected to a limit block. A return spring is installed at the bottom of the limit block. The cooperation between the guide cylinders 14 and the support columns 15 ensures the stability of the separation assembly 3 during operation and prevents displacement due to vibration. The return spring design automatically resets the position of the separation assembly 3 after the equipment stops, simplifying the operation process.

[0028] like Figure 1 As shown, the adjustment mechanism includes two sets of sliding grooves symmetrically opened in the top of the mounting frame. Each set of sliding grooves has a sliding block slidably connected in it. The upper end of the sliding block is movably connected to the inner top of the separation component 3 through a second connecting rod. A push-pull rod 11 is connected to one side of the inner wall of the sliding block. A first hydraulic chamber 9 is provided on one side of the push-pull rod 11. A first piston is slidably connected in the first hydraulic chamber 9. One end of the push-pull rod 11 extends into the first hydraulic chamber 9 and is connected to the first piston. One end of the first hydraulic chamber 9 is connected to a first hydraulic pipe. The lower end of the first hydraulic pipe passes through the support platform 2 and the fixing plate in sequence and is connected to a second hydraulic pipe. One end of the second hydraulic pipe is connected to a second hydraulic chamber 10. The second hydraulic chamber 10 is located in the base frame 1. A buffer spring 12 is provided in the second hydraulic chamber 10. The top of the buffer spring 12 is connected to a second piston. A support rod is connected to the upper end of the second piston. The upper end of the support rod passes through the support platform 2 and is inserted into the bottom of the separation component 3. The first hydraulic chamber 9 and the second hydraulic chamber 10 achieve height adjustment of the separation component 3 through hydraulic transmission. The introduction of the buffer spring 12 effectively absorbs the impact force generated during operation and extends the service life of the equipment.

[0029] The sealing of the first hydraulic chamber 9 and the second hydraulic chamber 10 is ensured by sealing rings. Sealing rings are provided between the first piston and the first hydraulic chamber 9, and between the second piston and the second hydraulic chamber 10. The upper end face of the second hydraulic pipe is in contact with the lower end face of the first hydraulic pipe, and two sets of sealing rings are provided inside the contact area, with sealing gaskets filling the inside of the two sets of sealing rings. The sealing rings have a U-shaped cross-section, and the two sets of sealing rings are fixedly connected to the inner walls of the first and second hydraulic pipes, respectively. The sliding groove has a T-shaped cross-section, and the two ends of the second connecting rod are hinged to the separation component 3 and the sliding block, respectively, ensuring the stable sliding of the sliding block within the sliding groove.

[0030] In practical applications, after the coal slime enters the separation component 3, it is evenly dispersed under the action of the diversion plate 13, avoiding local accumulation and blockage. The separation component 3 can be adjusted in height by an adjustment mechanism to adapt to different processing needs. When the height of the separation component 3 needs to be adjusted, hydraulic oil is injected into the first hydraulic chamber 9, the first piston pushes the push-pull rod 11 to move, the push-pull rod 11 drives the sliding block to slide in the sliding groove, and the sliding block pushes the separation component 3 up or down through the second connecting rod. At the same time, hydraulic oil is transmitted to the second hydraulic chamber 10 through the first hydraulic pipe and the second hydraulic pipe, the second piston pushes the support rod to move, and the support rod provides additional support force to the separation component 3. The buffer spring 12 plays a buffering role when the separation component 3 is subjected to impact, protecting the equipment from damage.

[0031] The modular design of the entire system allows for quick disassembly and assembly of functional components, facilitating maintenance and replacement. For example, when the separation component 3 requires maintenance, rotating the operating handle removes the locking pin 8 from the locking hole, allowing the fixing plate to be removed from the base frame 1 for maintenance of the separation component 3. After maintenance, the fixing plate is reinserted into the positioning slot, and the applied force is released. The locking pin 8 automatically inserts into the locking hole under the action of the compression spring, completing the installation. This design significantly improves the ease of operation and maintenance efficiency of the equipment, while also enhancing its flexibility under different processing scales or process requirements.

[0032] Through the detailed description of the structure and operating principle described above, the modular coal slime high-efficiency separation system of this utility model can effectively solve the problems of insufficient modularity, complex maintenance, and limited operating efficiency in existing technologies in practical applications, and has high practical value and promising prospects for promotion. In order to enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0033] In actual operation, the coal slurry is first fed into the separation component 3 via the feeding device. After entering the separation component 3, the coal slurry is evenly dispersed under the action of the diversion plate 13. The arc-shaped cross-section design of the diversion plate 13 guides the coal slurry to flow along a specific path, avoiding blockage caused by local accumulation. At the same time, the guide cylinder 14 and the support column 15 installed on the top of the mounting frame cooperate to ensure the stability of the separation component 3 during operation and prevent displacement caused by vibration. After the equipment stops, the design of the reset spring allows the separation component 3 to automatically reset to the initial position, thereby simplifying the operation process.

[0034] When the height of the separating assembly 3 needs to be adjusted to accommodate different processing requirements, hydraulic oil is injected into the first hydraulic chamber 9, which pushes the first piston to move. The movement of the first piston drives the push-pull rod 11 to move, and the push-pull rod 11 pushes the sliding block to slide within the sliding groove. Since the sliding groove has a T-shaped cross-section, and the two ends of the second connecting rod are hinged to the separating assembly 3 and the sliding block respectively, the movement of the sliding block is transmitted to the separating assembly 3 through the second connecting rod, causing it to rise or fall vertically. At the same time, hydraulic oil is transmitted to the second hydraulic chamber 10 through the first hydraulic pipe, pushing the second piston to move. The second piston provides additional support force to the separating assembly 3 through the support rod, ensuring its stability during operation. The buffer spring 12 acts as a buffer when the separating assembly 3 is subjected to impact, effectively absorbing the impact force and thus extending the service life of the equipment.

[0035] During equipment operation, if maintenance or replacement of the separation component 3 is required, it can be quickly disassembled by rotating the operating handle. Specifically, rotating the operating handle drives the rotating shaft 4 to rotate, and the guide rail on the rotating shaft 4 drives the transmission sleeve 5 to rotate synchronously. The rotation of the transmission sleeve 5 causes the drive arm 6 to shift, and the drive arm 6 pulls the first connecting rod to move. The first connecting rod pushes the push block 7 to move along the adjustment cavity. The movement of the push block 7 further drives the locking pin 8 to move out of the locking hole, thereby releasing the lock between the fixing plate and the base frame 1. At this time, the fixing plate can be removed from the positioning slot, and then the separation component 3 can be maintained or replaced. After maintenance, the fixing plate is reinserted into the positioning slot and the applied force is released. The compressed spring returns to its original deformation, pushing the locking pin 8 into the locking hole, completing the locking between the fixing plate and the base frame 1. This modular design significantly improves the ease of operation and maintenance efficiency of the equipment.

[0036] Furthermore, regarding the sealing performance of the hydraulic system, the first hydraulic chamber 9 and the second hydraulic chamber 10 are connected by a first hydraulic pipe and a second hydraulic pipe. Two sets of U-shaped sealing rings are installed inside the contact area between them, and these are filled with sealing gaskets. The sealing rings are fixedly connected to the inner walls of the first and second hydraulic pipes, respectively, ensuring that no leakage occurs during the transmission of hydraulic oil. Simultaneously, sealing rings are provided between the first piston and the first hydraulic chamber 9, and between the second piston and the second hydraulic chamber 10, further guaranteeing the sealing performance of the hydraulic system.

[0037] Through the detailed description of the above steps and operating principles, the modular coal slime high-efficiency separation system of this utility model can effectively solve the problems of insufficient modularity, complex maintenance, and limited operating efficiency in existing technologies in practical applications. The entire system achieves rapid disassembly and assembly of each functional component through modular design, significantly improving the ease of operation and maintenance efficiency of the equipment; the design of the adjustment mechanism enables precise adjustment of the separation component 3, enhancing the system's adaptability; and the introduction of the buffer spring 12 effectively absorbs the impact force generated during operation, extending the service life of the equipment. In summary, this utility model has high practical value and promising prospects for promotion.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
