Description

Technical Field

[0001] This utility model relates to the field of coal slurry water filtration technology, and in particular to coal slurry water concentration and separation equipment. Background Technology

[0002] During the coal washing and processing process, a large amount of coal slurry is generated. As the coal industry continues to raise the requirements for coal product quality, refined washing operations are becoming more and more common, which has led to a corresponding increase in the production of coal slurry. The indiscriminate discharge of untreated coal slurry can also cause serious environmental pollution, such as contaminating soil, surface water and groundwater, which does not meet environmental protection requirements.

[0003] The centrifugal force generated by high-speed rotation can quickly throw coal slime particles to the edge of the equipment, achieving separation from water. During this process, a large amount of coal slime-water mixture containing coal slime particles, mineral impurities, and water will be generated.

[0004] In existing technologies, coal slurry water is placed in a large sedimentation tank, relying on gravity to allow the coal slurry particles to naturally settle to the bottom, achieving preliminary separation of water and coal slurry. However, this process is prone to causing duct blockage and low efficiency. Therefore, a coal slurry water concentration and separation device is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a coal slurry water concentration and separation device, including a tank 1. The tank 1, as the main structure of the entire device, plays a crucial role in containing the coal slurry water. Its shape and material are carefully designed to withstand certain pressure and corrosion from the coal slurry water, providing a stable spatial environment for subsequent concentration and separation operations. A top cover 2 is slidably connected to the top of the tank 1. The top cover 2 can be easily opened or closed, facilitating maintenance and cleaning of the tank 1. Simultaneously, it provides a sealing effect during normal operation, preventing coal slurry water from overflowing and external impurities from entering the tank 1.

[0035] A protective shell 3 is fixedly connected to the top of the top cover 2. The protective shell 3 protects the internal components such as the motor 4 from external factors such as dust and moisture, extending the service life of the components and ensuring stable operation of the equipment. The motor 4 is fixedly connected to the inner top wall of the protective shell 3. The motor 4 serves as a power source, providing power support for the entire equipment's operation. It converts electrical energy into mechanical energy, driving the relevant components to work according to a set program, enabling the coal slurry water concentration and separation process to proceed in an orderly manner. A pulley 5 is fixedly connected to the drive end of the motor 4. Driven by the motor 4, the pulley 5 rotates, effectively transmitting the power of the motor 4 through its circular motion, driving other connected components to work in coordination.

[0036] The pulley 5 is externally connected to a track 6, which has good transmission performance. It can smoothly transmit the rotation of pulley 5 to pulley 7, ensuring stability during power transmission and adapting to certain tension changes, reducing the impact of problems such as jamming during transmission on the equipment. The end of the track 6 furthest from pulley 5 is slidably connected to pulley 7. Pulley 7 rotates under the drive of track 6, thereby driving other connected components to move synchronously. This, in conjunction with pulley 5, achieves the rational distribution and transmission of power among different components.

[0037] A protective column 8 is fixedly connected to the top of pulley 2 7. The protective column 8 serves two purposes: firstly, it connects pulley 2 7 to other components, and secondly, it provides protection for internal components such as the impact rod 10, ensuring that these components function properly during equipment operation without being disturbed by external collisions or other factors. The impact rod 10 is slidably connected to the inner wall of the protective column 8. The impact rod 10 can move with the rotation of the protective column 8. Through continuous movement, it can rhythmically strike the water inlet 30, thereby preventing the water inlet 30 from becoming clogged due to excessive coal slurry content, and ensuring that the coal slurry water can smoothly enter the tank 1.

[0038] A cylinder 11 is fixedly connected to the top of the impact rod 10. The cylinder 11 mainly serves to connect the impact rod 10 and the spring 12, and can slide stably within the inner wall groove 9 of the protective column 8, ensuring the normal movement trajectory of the impact rod 10 in conjunction with other components. A spring 12 is fixedly connected to one end of the impact rod 10 near the cylinder 11. The spring 12 has good elasticity. When the impact rod 10 strikes the water inlet 30, the spring 12 is compressed, allowing the impact rod 10 to spring back. This achieves effective striking of the water inlet 30 while preventing damage to the water inlet 30 due to rigid impact, ensuring the normal operation of the equipment.

[0039] The tank body 1 is externally fixedly connected to a sludge outlet 22, which serves as the channel for discharging the concentrated coal slurry from the tank body 1. This outlet guides the relatively concentrated coal slurry, after preliminary treatment, smoothly out of the tank body 1 and into the subsequent filtration stage, ensuring the continuity of the entire concentration and separation process. Internally, the tank body 1 is slidably connected to a rotating assembly for internal cleaning. This assembly rotates within the tank body 1, thoroughly cleaning the inner wall and preventing impurities such as coal slurry from adhering to the tank wall for extended periods, thus affecting the normal operation of the equipment and the concentration and separation effect. Externally, the sludge outlet 22 is fixedly connected to a fixing assembly for deep filtration. This fixing assembly securely installs the filtration components, ensuring that the filter components do not loosen or shift during deep filtration of the coal slurry, guaranteeing the stability and reliability of the filtration effect.

[0040] The tank body 1 is externally fixedly connected to a drain outlet 29, which is the final drainage channel for the equipment. After a series of concentration, separation, and filtration treatments, the water can be discharged to a designated location, such as a sewage treatment system or a reuse system, through the drain outlet 29, ensuring the normal functioning of the equipment's drainage and meeting actual production and environmental protection requirements. The top inner wall of the top cover 2 is fixedly connected to a water inlet 30, which is the inlet for coal slurry water to enter the tank body 1. Its position and structural design are reasonable, ensuring that the coal slurry water flows into the tank body 1 evenly and stably. Furthermore, through the anti-clogging knocking action of the impact rod 10, a good water inlet condition can always be maintained, providing a sufficient material foundation for subsequent concentration and separation operations.

[0041] The end of the impact rod 10 furthest from the protective column 8 is coupled to the outer wall of the inlet 30. This coupling allows the impact rod 10 to precisely strike the inlet 30 during rotation, promptly cleaning any coal sludge or other impurities that may adhere to the outer wall of the inlet 30. This prevents blockage of the inlet 30 due to impurity accumulation and ensures smooth flow of the coal sludge water. Four support columns 21 are fixedly connected to the bottom of the tank 1. These support columns provide stable support for the entire equipment, bearing the weight of the equipment itself and the load from the coal sludge water inside the tank 1. This ensures that the equipment will not shake or tilt during operation, guaranteeing stable operation and proper coordination between components.

[0042] Reference Figures 4 to 6 ,

[0043] The rotating assembly includes a motor 4, which serves as the core power source, continuously outputting stable power to drive connected components to rotate. This enables operations such as cleaning the interior of tank 1 and agitating the coal slurry, ensuring the orderly operation of coal slurry concentration and separation within the equipment. A rotating shaft 15 is fixedly connected to the drive end of the motor 4. Driven by the motor 4, the rotating shaft 15 rotates. As a key component connecting the motor 4 to other parts, it transmits the rotational force of the motor 4 to components such as the follower rods 16. Its strength and rigidity ensure that no deformation occurs during rotation, guaranteeing stable power transmission. Multiple follower rods 16 are fixedly connected to the rotating shaft 15 away from the motor 4. These follower rods 16 rotate in a circular motion as the rotating shaft 15 rotates, distributing the rotational force and driving a wider range of components to move in tandem. This allows for corresponding operations at different locations within tank 1, improving the comprehensiveness and effectiveness of the equipment's operation.

[0044] A fixing block 17 is fixedly connected to the end of the follower rod 16 away from the rotating shaft 15. The fixing block 17 connects the follower rod 16 and the telescopic column 18, firmly binding them together to ensure the continuity of power transmission and structural stability during equipment operation, allowing subsequent cleaning and other operations to proceed smoothly. Two telescopic columns 18 are fixedly connected to the end of the fixing block 17 away from the follower rod 16. The telescopic columns 18 have telescopic characteristics and can adaptively extend and retract according to the actual conditions of the inner wall of the tank 1, ensuring that the scraper 19 can always fit tightly against the inner wall of the tank 1, effectively scraping away coal sludge and other impurities adhering to the wall and improving the cleaning effect. Two telescopic columns 18 are fixedly connected to scraper 19 at the ends away from the fixed block 17. The scraper 19 directly contacts the inner wall of the tank 1. Driven by components such as follower rod 16 and telescopic column 18, it scrapes along the tank wall, which can scrape off the coal sludge and other impurities accumulated on the wall, preventing them from accumulating and affecting the normal operation of the equipment and the concentration and separation quality of coal sludge water, and keeping the internal environment of the tank 1 clean.

[0045] The fixed components include a sludge outlet 22, which not only serves as a channel for the thick coal slurry to flow out of the tank 1, but also provides a foundation for the installation of subsequent fixed components. This allows all filtration-related parts to be rationally arranged around it, ensuring that the coal slurry can smoothly enter the filtration stage for deep treatment. An outlet 28 is externally fixedly connected to the sludge outlet 22. The outlet 28 is a channel for the discharge of relatively clear water after deep filtration. The filtered water can be properly collected or discharged through the outlet 28, ensuring the normal functioning of the equipment's drainage and preventing water accumulation that could affect equipment operation. Three filter plates 24 are internally slidably connected to the outlet 28. These three filter plates 24 are layered to filter the coal slurry flowing out of the sludge outlet 22 multiple times, gradually removing impurities and making the filtration effect more significant. After filtration, the water quality of the coal slurry is significantly improved, bringing it closer to the standards for discharge or subsequent reuse.

[0046] Multiple clamping plates 25 are fixedly connected to the top of the filter box 23. These clamping plates 25 tightly hold the filter plates 24, preventing them from loosening, shifting, or even falling off during operation due to water flow impact, vibration, or other factors. This ensures the filter plates 24 remain in the correct position and function stably. Rotating blocks 26 are slidably connected inside two clamping plates 25. These blocks can rotate appropriately within the clamping plates 25, facilitating the installation and removal of the filter plates 24. During normal operation, they also cooperate with the clamping plates 25 to fix the filter plates 24 from different angles, enhancing the fixing effect.

[0047] Each of the multiple filter plates 24 has a fixing hole 27 on its top. The fixing hole 27 provides a fixed position for the rotating block 26. After the rotating block 26 is inserted into the fixing hole 27, it can effectively limit the filter plate 24 from above. Working together with the clamping plate 25, it can firmly fix the filter plate 24 in both horizontal and vertical directions, further ensuring the stability of the filter plate 24 during the filtration process. The end of the rotating block 26 away from the clamping plate 25 is slidably connected to the inner wall of the fixing hole 27. This connection method allows the rotating block 26 to move to a certain extent within the fixing hole 27, which is convenient for installation and adjustment. At the same time, it can maintain a relatively fixed state by relying on friction with the fixing hole 27 during equipment operation, preventing the filter plate 24 from moving accidentally. The filter plate 24 is fixedly connected to the outside of the filter plate 24. The water outlet 28 is tightly connected to the filter plate 24, so that the water filtered by the filter plate 24 can be smoothly discharged through the water outlet 28, ensuring the continuity of the entire filtration and drainage system and avoiding problems such as poor water flow that affect filtration efficiency and overall equipment performance.

[0048] Reference Figure 1 , Figure 4 and Figure 5 ,

[0049] Three bent plates 20 are fixedly connected to the end of the rotating shaft 15 away from the motor 4. The three bent plates 20 rotate together with the rotating shaft 15. They can agitate the coal slurry water in the tank 1, causing the relatively thick coal slurry water to gather towards the outlet 22 under the action of centrifugal force generated by the rotation. This makes it easier to discharge the thick coal slurry water that needs further treatment out of the tank 1. At the same time, it can also play a certain role in mixing the coal slurry water in the tank, making the subsequent concentration and separation operation more uniform and efficient.

[0050] The bottoms of the three curved plates 20 are slidably connected to the inner wall of the tank 1. This sliding connection ensures that the curved plates 20 have a relatively stable movement trajectory during rotation, reduces frictional wear between them and the inner wall of the tank 1, extends the service life of the curved plates 20, and better guides the flow direction of the coal slurry, improving the working efficiency of the equipment. The end of the telescopic column 18 away from the two fixed blocks 17 is slidably connected to the inner wall of the tank 1. This sliding connection allows the telescopic column 18 to be flexibly adjusted according to the specific shape and condition of the inner wall of the tank 1, ensuring that the scraper 19 can always adhere to the tank wall for cleaning. Regardless of whether there are local unevenness or deformation of the tank wall, a good cleaning effect can be achieved, maintaining the cleanliness of the inside of the tank 1.

[0051] A fixed column 13 is slidably connected to the bottom of pulley 2 7. The fixed column 13 provides support and limits to pulley 2 7, ensuring a stable vertical position during rotation and preventing excessive vertical displacement that could affect the connection and transmission effect with components such as the track 6, thus ensuring the stability of power transmission. An operating platform 14 is fixedly connected to the bottom of the fixed column 13. The operating platform 14 provides operators with a platform to operate and observe the equipment's operation, facilitating the monitoring of the working status of various components and enabling timely detection and handling of potential problems to ensure normal equipment operation. The end of the operating platform 14 furthest from the fixed column 13 is fixedly connected to the outside of the tank body 1. This connection method makes the operating platform 14 and the tank body 1 a relatively stable whole, preventing instability caused by slight vibrations during operation, thus improving operational safety and convenience.

[0052] The inner wall of the protective column 8 is provided with a sliding groove 9, which provides a track for the cylinder 11 to slide. This allows the cylinder 11 to slide stably and smoothly along the inner wall of the protective column 8 in a set direction, thereby ensuring that the impact rod 10 can move according to the expected trajectory, achieving effective impact and anti-clogging functions on the water inlet 30. The outer surface of the cylinder 11 is slidably connected to the inner wall of the cylinder 11. Through this sliding connection, the cylinder 11 can move flexibly within the sliding groove 9. Together with components such as the spring 12, the impact rod 10 can generate sufficient impact force to clean the water inlet 30 when it hits it, and can also rebound smoothly after impact due to the elasticity of the spring 12, ensuring the normal operation of the equipment and the unobstructed flow of the water inlet 30.

[0053] Working principle: When coal slurry water enters tank 1 through inlet 30, motor 4 is turned on, driving rotating shaft 15 and pulley 5 to rotate. The rotation of pulley 5 drives pulley 7 to rotate, and the protective column 8 at the top of pulley 7 begins to rotate with the rotation of pulley 7. The impact rod 10 inside the protective column 8 continuously strikes the inlet 30 as it rotates, preventing the coal slurry water from becoming too clogging. When the impact rod 10 strikes the inlet 30, it will spring back, achieving the effect of striking without damaging the inlet 30. When rotating shaft 15 rotates, follower rod 16 also rotates, and telescopic column 18 at one end of fixed block 17 slides away from the two fixed blocks 17. Connected to the inner wall of tank 1, this sliding connection allows the telescopic column 18 to be flexibly adjusted according to the specific shape and condition of the inner wall of tank 1, ensuring that the scraper 19 can always adhere to the tank wall for cleaning. Regardless of whether there are local unevenness or deformation of the tank wall, a good cleaning effect can be achieved, maintaining the clean state inside tank 1. The bending plate 20 at the bottom of the rotating shaft 15 rotates, driving the relatively thick coal slurry water through the sewage outlet 22 into the filter box 23 for secondary filtration. The coal slurry water is filtered multiple times by three filter plates 24. The clamping plate 25 at the top of the filter plate 24 holds the rotating block 26 to fix the filter plate 24 and prevent it from falling off during use.
