[0026] Example 1

[0027] Reference Figure 1-4 The first embodiment of this utility model provides a processing component 1 including a feed inlet 101, a coal ash box 102, a signal antenna 103, and a support column 104. The feed inlet 101 is located at the upper end of the coal ash box 102. The front end of the coal ash box 102 is fixedly connected to the surface of the signal antenna 103. The surface of the support column 104 is fixedly connected to the surface of the coal ash box 102. A screening mechanism 2 is provided inside the coal ash box 102, and a cleaning mechanism 3 is provided on the surface of the coal ash box 102. The screening mechanism 2 is used to screen the coal ash by size, and the cleaning mechanism 3 is used to discharge the screened coal ash.

[0028] Specifically, the coal ash treatment component 1, through the setting of the feed inlet 101, the screening mechanism 2, and the cleaning mechanism 3, effectively solves the problems of low screening efficiency, inconvenient cleaning, and insufficient automation in the traditional coal ash treatment process. After the coal ash enters the coal ash box 102 through the feed inlet 101, the screening mechanism 2 can achieve step-by-step separation of coal ash particles, improving the processing efficiency; while the cleaning mechanism 3 can promptly discharge the large coal ash particles after screening, avoiding blockage and the inconvenience of manual cleaning. The setting of the signal antenna 103 further improves the operation of the equipment, making it easier for staff to grasp the cleaning time in real time and ensuring the continuous and stable operation of the system.

[0029] Furthermore, in the coal ash treatment process, the coal ash generated in the boiler is first poured into the box body through the feed port 101 opened at the top of the coal ash box 102, the coal ash is screened by the screening mechanism 2, and the screened coal ash is discharged by the cleaning mechanism 3.

[0030] Example 2

[0031] The second embodiment of this utility model provides a screening mechanism 2 including a screening motor 201, a screening plate 202, a guide rod 203, and a spring 204. The screening motor 201 is disposed in front of the screening plate 202. The inner wall of the screening plate 202 is slidably connected to the surface of the guide rod 203. The spring 204 is sleeved on the surface of the guide rod 203. The surface of the screening motor 201 is fixedly connected to the surface of the coal ash box 102. The lower end of the screening motor 201 is fixedly connected to the upper end of the support column 104. The lower end of the spring 204 is fixedly connected to the upper end of the screening plate 202. The upper end of the spring 204 is fixedly connected to the inner wall of the coal ash box 102. The surface of the screening plate 202 is slidably connected to the inner wall of the coal ash box 102. Both ends of the guide rod 203 are fixedly connected to the inner wall of the coal ash box 102.

[0032] Specifically, the screening mechanism 2, through the coordinated action of the screening motor 201, the three-layer screening plate 202, the guide rod 203, and the spring 204, effectively solves the problems of low screening accuracy, low screening efficiency, and poor equipment vibration stability in the coal ash treatment process. The screening plate 202 slides along the guide rod 203 and achieves stable reciprocating vibration under the drive of the screening motor 201 and the rebound action of the spring 204, so that the coal ash can be efficiently classified in the screening plate 202 with progressively smaller screen holes, improving the screening continuity and processing capacity. This structure not only enhances the screening effect but also reduces the risk of screen hole blockage, providing a good pretreatment foundation for subsequent cleaning and discharge, thereby improving the operating efficiency and reliability of the entire coal ash treatment system.

[0033] Furthermore, to achieve effective screening of coal ash, the coal ash box 102 is equipped with three layers of screening plates 202, with the screen aperture size decreasing from top to bottom to form a step-by-step filtration. The inner wall of the screening plate 202 slides in fit with the surface of the guide rod 203, and a spring 204 is sleeved on the outside of the guide rod 203. The two ends of the spring 204 are fixedly connected to the upper end of the coal ash box 102 and the upper end of the screening plate 202, respectively. When the screening motor 201 installed on the outer wall of the coal ash box 102 is started, its output shaft drives the screening plate 202 to reciprocate along the direction of the guide rod 203. During the movement, the spring 204 is subjected to periodic compression and rebound, thereby enhancing the vibration effect of the screening plate 202 and improving the screening efficiency. After screening, the coal ash is separated step by step according to the particle size. The smaller coal ash particles continue to move downwards, passing through each layer of screening plate 202 in sequence, and finally being discharged from the discharge port at the bottom of the coal ash box 102, completing the preliminary treatment. The larger coal ash particles, unable to pass through the screen holes of the current layer, slide along the slope on one side of the screening plate 202 under the action of vibration and concentrate in the cleaning plate 402 area.

[0034] Example 3

[0035] The third embodiment of this utility model provides a cleaning mechanism 3 including a fixed ring 301, a servo motor 302, a protective cover 303, a transmission component 304, a tension wheel 305, and a fixed plate 306. The inner wall of the fixed ring 301 is fixedly connected to the surface of the servo motor 302, the surface of the servo motor 302 is fixedly connected to the surface of the protective cover 303, the output end of the servo motor 302 is drive-connected to the surface of the transmission component 304, the surface of the transmission component 304 is drive-connected to the surface of the tension wheel 305, the surface of the tension wheel 305 is fixedly connected to the surface of the fixed plate 306, the surface of the fixed ring 301 is fixedly connected to the surface of the protective cover 303, and the surface of the tension wheel 305 is rotatably connected to the surface of the ash box 102. The tension wheel 305 and the transmission component 306 are connected to each other. All 04 are located inside the protective cover 303. The surface of the protective cover 303 is fixedly connected to the surface of the coal ash box 102. The surface of the fixing plate 306 is rotatably connected to the inner wall of the protective cover 303. The rear end of the cleaning mechanism 3 is provided with a cooperating mechanism 4. The cooperating mechanism 4 includes a connecting plate 401, a cleaning plate 402 and a sensor 403. The surface of the connecting plate 401 is fixedly connected to the surface of the cleaning plate 402. The surface of the cleaning plate 402 is fixedly connected to the surface of the sensor 403. The lower end of the cleaning plate 402 is rotatably connected to the inner wall of the coal ash box 102 through a rotating shaft. The surface of the connecting plate 401 is fixedly connected to the surface of the fixing plate 306. The inner wall of the cleaning plate 402 is in contact with the surface of the screening plate 202. The surface of the connecting plate 401 is in contact with the surface of the coal ash box 102.

[0036] Specifically, the cleaning mechanism 3, through the coordinated operation of the fixed ring 301, servo motor 302, protective cover 303, transmission component 304, tension wheel 305, and fixed plate 306, solves the problems of large coal ash particles being difficult to effectively discharge and manual cleaning being inconvenient in traditional coal ash treatment equipment. The servo motor 302 drives the tension wheel 305 to rotate through the transmission component 304, and the tension wheel 305 is connected to the fixed plate 306. The fixed plate 306 is then connected to the cleaning plate 402 through the connecting plate 401. When the sensor 403 detects that the accumulated large coal ash particles have reached a preset height, it will trigger the signal antenna 103 to send a cleaning prompt message to the staff. At this time, the servo motor 302 inside the protective cover 303 is started, and its output shaft drives the transmission component 304 to rotate the tension wheel 305. The fixed plate 306 pulls the connecting plate 401, thereby allowing the cleaning plate 402 to rotate around the shaft and open, facilitating the discharge of accumulated large coal ash particles.

[0037] Furthermore, as large particles of coal ash accumulate, when the accumulation reaches a set height, the sensor 403 installed on the cleaning plate 402 will detect the signal change and send a prompt message outward through the signal antenna 103, reminding the staff to carry out cleaning operations in a timely manner. To facilitate the cleaning of residual coal ash, the equipment is equipped with a cleaning mechanism 3, which includes a servo motor 302, a transmission component 304, a tensioning wheel 305, and a fixing plate 306 installed on the outside of the coal ash box 102. The tensioning wheel 305 has a connecting plate fixed to its surface. Plate 401 is connected to the other end of the cleaning plate 402. In addition, the cleaning plate 402 and the coal ash box 102 are rotatably connected through a rotating shaft. When the staff receives the cleaning signal, they can start the servo motor 302 in the protective cover 303. The motor output shaft drives the transmission component 304 to work, so that the tension wheel 305 rotates and drives the fixed plate 306 to move synchronously, thereby pulling the cleaning plate 402 to rotate around the rotating shaft, opening the cleaning plate 402, so that the accumulated large particles of coal ash can be discharged smoothly, completing the entire cleaning process.

[0038] Working principle:

[0039] In the coal ash treatment process, the coal ash generated in the boiler is first poured into the coal ash box 102 through the inlet 101 at the top. To achieve effective screening of the coal ash, three layers of screening plates 202 are installed inside the coal ash box 102, with the screen aperture size decreasing from top to bottom, forming a step-by-step filtration. The inner wall of the screening plate 202 slides against the surface of the guide rod 203. A spring 204 is sleeved on the outside of the guide rod 203, and the two ends of the spring 204 are fixedly connected to the upper end of the coal ash box 102 and the upper end of the screening plate 202, respectively. When the screen installed on the outer wall of the coal ash box 102... After the motor 201 starts, its output shaft drives the screening plate 202 to reciprocate along the guide rod 203. During this process, the spring 204 is subjected to periodic compression and rebound, thereby enhancing the vibration effect of the screening plate 202 and improving screening efficiency. The coal ash after screening is separated according to particle size. Smaller coal ash particles continue to move downwards, passing through each layer of screening plates 202 in sequence, and finally being discharged from the discharge port at the bottom of the coal ash box 102, completing the preliminary treatment. Larger coal ash particles, unable to pass through the screen holes of the current layer, are discharged along the screen under the action of vibration. The slope on one side of the dividing plate 202 slides and concentrates in the area of ​​the cleaning plate 402. As large particles of coal ash accumulate, when the accumulation reaches a set height, the sensor 403 installed on the cleaning plate 402 will sense the signal change and send a prompt message outward through the signal antenna 103 to remind the staff to carry out cleaning operations in time. In order to facilitate the cleaning of residual coal ash, the equipment is equipped with a cleaning mechanism 3. This mechanism includes a servo motor 302, a transmission component 304, a tensioning wheel 305, and a fixing plate 306 installed on the outside of the coal ash box 102. The tensioning wheel... A connecting plate 401 is fixed to the surface of 305. The other end of the connecting plate 401 is connected to the cleaning plate 402. In addition, the cleaning plate 402 and the coal ash box 102 are rotatably connected through a rotating shaft. When the staff receives the cleaning signal, they can start the servo motor 302 in the protective cover 303. The motor output shaft drives the transmission component 304 to work, causing the tension wheel 305 to rotate and drive the fixed plate 306 to move synchronously, thereby pulling the cleaning plate 402 to rotate around the rotating shaft, opening the cleaning plate 402, so that the accumulated large particles of coal ash can be discharged smoothly, completing the entire cleaning process.

[0040] In summary, the coordinated operation of the screening motor, three-layer screening plates, guide rods, springs, and discharge port enables step-by-step screening and efficient separation of coal ash particles, improving the efficiency of coal ash treatment. Simultaneously, the synergistic action of the cleaning plate, sensors, signal antenna, and cleaning mechanism (including servo motors, transmission components, tensioning wheels, and fixing plates) achieves automatic accumulation sensing and cleaning control of large coal ash particles, realizing automated and continuous operation of the coal ash treatment process and enhancing the stability and ease of maintenance of the equipment.
