Description

Technical Field

[0001] This utility model relates to the field of filter press equipment technology, and in particular to an automatic unloading device for coal slime filter press. Background Technology

[0002] Coal slime filtration is a crucial process in coal washing, wastewater treatment, and other fields, its core function being the solid-liquid separation achieved through filtration equipment. In traditional filtration processes, coal slime unloading relies heavily on manual labor or simple mechanical devices, resulting in low efficiency and high labor intensity. With the development of automation technology, there is an urgent need for an automatic unloading device for coal slime filtration that can achieve efficient unloading and automatic cleaning, to meet the demands of modern industrial production for automation and efficiency.

[0003] Currently, most common coal slime unloading devices employ fixed scraper or hydraulic pusher structures, using a linear drive mechanism to move the scraper and complete the unloading process. Some devices are also equipped with a high-pressure water washing system, using nozzles at a fixed angle to wash the filter plates. These devices typically use an electric motor or hydraulic cylinder as a power source, achieving the reciprocating motion of the scraper through gear and rack or chain transmission. Their control systems often employ PLC or relay logic control.

[0004] However, existing unloading devices generally suffer from incomplete scraping and poor motion stability when handling high-viscosity coal slime. Due to the lack of effective limiting mechanisms and optimized linkage transmission design, the scraper is prone to jamming or deviation during operation, resulting in reduced unloading efficiency, seriously affecting production continuity, and increasing the frequency of manual intervention and maintenance. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic unloading device for coal slime filter press, which aims to improve the problems of incomplete scraping and poor movement stability that are common in the unloading devices of the prior art when processing high-viscosity coal slime.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic unloading device for coal slime filter press, comprising a support frame, a support plate fixedly connected to the upper surface of the support frame, a second fixing plate fixedly connected to the lower surface of the support plate, and a scraping assembly disposed below the second fixing plate;

[0007] The scraping assembly includes a scraper, which is disposed below a second fixed plate. A motor is fixedly connected to the outer wall of the second fixed plate, and a rotating disk is fixedly connected to the output end of the motor. A third fixed plate is attached to the outer wall of the rotating disk, and a first fixed column is fixedly connected to the outer wall of the rotating disk.

[0008] Furthermore, a filter plate is slidably connected to the inner wall of the support frame, and a fixing plate is fixedly connected to the lower surface of the support plate, with a rotating component disposed inside the fixing plate.

[0009] Furthermore, the rotating assembly includes a gear, which is disposed inside a fixed plate. A cylinder is fixedly connected to the inner wall of the fixed plate, and a rack is fixedly connected to the output end of the cylinder. The rack meshes with the gear. A connecting pipe is fixedly connected inside the gear, and a nozzle is fixedly connected to one end of the connecting pipe.

[0010] Furthermore, the upper surface of the fixing plate three is fixedly connected to the lower surface of the support plate, and the outer wall of the connecting rod two is slidably connected to the inner wall of the fixing plate two.

[0011] Furthermore, the connecting rod is attached to the outer wall of the rotating disk, which is located below the support plate.

[0012] Furthermore, the lower surface of the rack is slidably connected to an inner wall of the fixed plate, and the outer wall of the connecting pipe is slidably connected to an inner wall of the fixed plate.

[0016] 1. In this utility model, the rotating disk is driven by a motor, and the linkage mechanism enables the scraper to stably complete the lateral reciprocating motion, thereby achieving efficient automatic scraping.

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-4An embodiment of this utility model is provided: an automatic unloading device for coal slime filter press, including a support frame 1, which provides structural support and installation foundation for the entire device. A support plate 2 is fixedly connected to the upper surface of the support frame 1, which connects and fixes the installation platform of the upper structure. A fixing plate 9 is fixedly connected to the lower surface of the support plate 2, which serves as the installation base for the scraping assembly and provides motion guidance. A scraping assembly is provided below the fixing plate 9.

[0027] The scraping assembly includes a scraper 17 that directly contacts the filter plate 4 to perform coal slime scraping. The scraper 17 is positioned below the fixed plate 9. A motor 10 is fixedly connected to the outer wall of the fixed plate 9 to provide rotational power to the scraping assembly. A rotating disk 12 is fixedly connected to the output end of the motor 10, serving as a key transmission component that converts the rotational motion of the motor 10 into reciprocating motion. A fixed plate 11 is attached to the outer wall of the rotating disk 12 to limit its range of motion and ensure operational stability. A fixed column 13 is fixedly connected to the outer wall of the rotating disk 12 to control the rotation of the rotating disk 12. The rotational motion is transmitted to connecting rod 14. Connecting rod 14 is rotatably connected to the outer wall of fixed column 13, converting the rotational motion into a reciprocating swing linkage mechanism. Fixed column 2 15 is rotatably connected inside connecting rod 14, transmitting the swing of connecting rod 14 to connecting plate 16. One end of fixed column 2 15 is fixedly connected to connecting plate 16, connecting and transmitting motion to connecting rod 2 18. Connecting rod 2 18 is fixedly connected to the lower surface of connecting plate 16, ultimately transmitting the motion to the actuator linkage of scraper 17. One end of connecting rod 2 18 is fixedly connected to scraper 17.

[0028] Specifically, when the device is unloading coal slime, the motor 10 on the support frame 1 starts and drives the rotating disk 12 to rotate at a constant speed. The fixed column 13 rotates synchronously with the rotating disk 12. Through the transmission action of the connecting rod 14, the fixed column 2 15 is driven to swing back and forth in the horizontal plane. The reciprocating motion of the fixed column 2 15 pushes the connecting plate 16 and the connecting rod 2 18 to slide precisely in a straight line along the guide groove on the inner wall of the fixed plate 2 9, so that the scraper 17 can achieve stable lateral reciprocating motion below the fixed plate 2 9. During this process, the scraper 17 maintains a constant contact pressure with the surface of the filter plate 4 to ensure that the coal slime is completely scraped off. The fixed plate 3 11 effectively restricts the radial displacement of the rotating disk 12 through the tight fit between its inner wall and the outer edge of the rotating disk 12, ensuring the operational stability of the entire scraping assembly.

[0029] Reference Figures 1-5A filter plate 4 is slidably connected to the inner wall of the support frame 1, serving as the working surface for coal slime pressing. This requires regular cleaning. A fixed plate 3 is fixedly connected to the lower surface of the support plate 2, acting as the mounting base and motion guide structure for the rotating assembly. The fixed plate 3 contains a rotating assembly, including a gear 6 and an angle-adjusting transmission component that drives the connecting pipe 7 to rotate. The gear 6 is located inside the fixed plate 3. A cylinder 21 is fixedly connected to the inner wall of the fixed plate 3, providing linear power for adjusting the angle of the nozzle 8. A rack 5 is fixedly connected to the output end of the cylinder 21, converting the linear motion of the cylinder 21 into the rotational motion of the gear 6. The rack 5 meshes with the gear 6. A connecting pipe 7 is fixedly connected inside the gear 6, connecting the nozzle 8 and transmitting its rotational motion. One end of pipe 7 is fixedly connected to a nozzle 8, which is the actuator for spraying cleaning fluid. The upper surface of fixed plate 3 11 is fixedly connected to the lower surface of support plate 2. The outer wall of connecting rod 2 18 is slidably connected to the inner wall of fixed plate 2 9. Connecting rod 1 14 is attached to the outer wall of rotating disk 12. Rotating disk 12 is located below support plate 2. The lower surface of rack 5 is slidably connected to the inner wall of fixed plate 3. The outer wall of connecting pipe 7 is slidably connected to the inner wall of fixed plate 3. One end of connecting pipe 7 is fixedly connected to connecting pipe 2 19, which is the conveying pipeline connecting water tank 20 and connecting pipe 7. One end of connecting pipe 2 19 is fixedly connected to water tank 20, which is a pressure vessel for storing and providing cleaning fluid. Filter plate 4 is located on one side of the outer wall of support plate 2. Water tank 20 is located below support frame 1.

[0030] Specifically, when the device needs to perform cleaning operations, the piston rod of cylinder 21 extends, pushing rack 5 to slide smoothly in the guide rail of fixed plate 3. The meshing transmission between rack 5 and gear 6 causes gear 6 to rotate. Gear 6 drives connecting pipe 7 to rotate synchronously through key connection. The rotational motion of connecting pipe 7 is transmitted to nozzle 8 to realize automatic adjustment of spray angle. At the same time, the cleaning liquid in water tank 20 is transported to nozzle 8 through connecting pipe 19 and connecting pipe 7. Under pressure, it forms a fan-shaped water curtain and is sprayed onto the surface of filter plate 4. The angle adjustment function of nozzle 8 ensures that the cleaning liquid can cover the entire working surface of filter plate 4, effectively removing residual coal sludge.

[0031] Working principle: When the automatic unloading device for coal slime filter press is used, when unloading coal slime, the motor 10 on the support frame 1 drives the rotating disk 12 to rotate, and the first fixed column 13 rotates synchronously with the rotating disk 12. Through the first connecting rod 14, the second fixed column 15 is driven to swing back and forth. The second fixed column 15 pushes the connecting plate 16 and the second connecting rod 18 to slide along the inner wall of the second fixed plate 9, so that the scraper 17 moves laterally back and forth below the second fixed plate 9 to scrape the coal slime off the surface of the filter plate 4. The third fixed plate 11 limits the displacement range of the rotating disk 12 to ensure the stable operation of the scraping assembly.

[0032] In addition, when the device is finished and the filter plate 4 needs to be cleaned, the cylinder 21 pushes the rack 5 to slide in the fixed plate 3, which drives the gear 6 that meshes with it to rotate. The gear 6 drives the nozzle 8 to rotate synchronously through the connecting pipe 7, so as to realize the automatic adjustment of the spray angle. The connecting pipe 7 and the connecting pipe 19 are connected to the water tank 20, and the water flows out through the nozzle 8 to clean the filter plate 4.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
