Description

Technical Field

[0001] This utility model relates to the field of slag discharge machine technology, specifically a slag discharge machine with anti-clogging function. Background Technology

[0002] A slag remover is a boiler slag removal device. After coal combustion in a boiler, the resulting slag is pushed by the grate into the slag pit. It is then crushed into small pieces by a slag crusher and discharged using the slag remover to clear the slag and prevent its accumulation. Most existing slag removers consist of a screw conveyor. The crushed slag enters the machine through the screw conveyor's inlet and is propelled forward by rotating screw conveyor blades. As the screw conveyor blades rotate, the slag moves forward along the bottom of the conveyor trough due to its own weight and the friction between the blades and the inner wall of the screw conveyor, thus achieving slag discharge. Traditional slag removers rely on the rotation of the screw conveyor blades to transport the slag. When the slag volume is large, the inlet and outlet of the screw conveyor can become blocked due to the large accumulation of slag, requiring a slowing down of the discharge speed and manual clearing with steel rods, which is quite troublesome. Therefore, we propose a slag remover with anti-blocking functionality. Utility Model Content

It is equipped with an anti-clogging slag discharge mechanism. The slag at the feed inlet is kept loose by the continuous stirring of the stirring component. The slag at the discharge outlet is quickly removed by the rotation of the slag removal component, which avoids the accumulation of slag at the feed inlet and discharge outlet and achieves the purpose of anti-clogging. It can effectively solve the problems in the background technology.

The slag skimmer component is located on the front side inside the shell and is equipped with an anti-clogging slag discharge mechanism. The continuous stirring of the stirring component keeps the slag at the feed inlet loose. The rotation of the slag skimmer component quickly removes the slag at the discharge outlet, preventing slag from accumulating at the feed inlet and discharge outlet, thus achieving the purpose of preventing clogging.

The slag discharge component 44 is located in the middle of the inside of the shell 1. The transmission component 43 is used for stable transmission of the agitating component 42 and the slag discharge component 44. The slag scraping component 45 is located on the front side of the inside of the shell 1. The agitating component 42 includes an agitating frame 421 and a limiting groove 422. The agitating frame 421 is slidably connected to the upper end of the outer surface of the rotating shaft 41. The limiting groove 422 is opened in the inner wall of the feed hopper 3. The limiting groove 422 is composed of two grooves, left and right, both of which are opened inside the wall of the feed hopper 3. Both grooves are higher at the front and higher at the back. The two troughs are connected end to end. The outer end of the agitator 421 is fitted with the inner wall of the limiting groove 422, which can quickly agitate the slag at the feed inlet. The agitator assembly 42 also includes a scraper 423, which is set at the lower end of the outer surface of the rotating shaft 41. The lower end of the scraper 423 is fitted with the bottom wall of the feed hopper 3, which can quickly scrape off the slag below the feed hopper 3. The slag discharge assembly 44 includes a central shaft 441, a spiral conveyor 442, and a scraper 443. The central shaft 441 is rotatably connected to the middle of the interior of the housing 1. The spiral conveyor 442 is set on the outer surface of the central shaft 441. The outer edge of the spiral conveyor 442 is fitted with the inner wall of the housing 1. The scraper 443 is set at the lower end of the outer surface of the spiral conveyor 442, which scrapes... The lower end of bar 443 is fitted into the inner wall of shell 1 for rapid slag transport. The slag-removing assembly 45 includes gear 1 451, gear 2 452, and a slag-removing frame 453. Gear 1 451 is located at the front end of the central shaft 441. The slag-removing frame 453 is rotatably connected to the middle of the discharge port 2. The outer surface of the slag-removing frame 453 is evenly provided with teeth of varying lengths, allowing for rapid slag removal. Gear 2 452 is located at the front end of the slag-removing frame 453. Gear 1 451 and gear 2 452 mesh together, allowing for rapid slag removal from the discharge port 2. The transmission assembly 43 includes a transmission shaft 431, bevel gear 1 432, bevel gear 2 433, a pulley 434, and a motor 435. The transmission shaft 431 is rotatably connected to the lower end of the feed hopper 3. In this configuration, bevel gear 432 is located at the front end of drive shaft 431, and bevel gear 433 is located at the lower end of shaft 41. Bevel gear 432 and bevel gear 433 mesh with each other. Both drive shaft 431 and central shaft 441 have pulleys 434 at their rear ends. The diameter of the upper pulley 434 is smaller than that of the lower pulley 434. The two pulleys 434 are connected by a belt drive. Motor 435 is located at the upper rear side of housing 1. The input end of motor 435 is electrically connected to the output end of microcontroller 5. The front end of the output shaft of motor 435 is fixedly connected to the rear end of the lower pulley 434, providing a foundation for slag clearing and conveying. An anti-clogging slag discharge mechanism 4 is provided, which keeps the slag at the feed inlet loose through continuous agitation by stirring component 42.The slag removal assembly 45 quickly removes slag from the discharge port 2 by rotating, preventing slag accumulation at the inlet and outlet and thus preventing blockages.

[0026] The working principle of the slag discharger with anti-clogging function provided by this utility model is as follows: When using the slag discharger for slag discharge, the upper end of the feed hopper 3 is bolted to the lower end of the discharge port of the external slag crusher. The slag after being crushed by the external slag crusher falls into the feed hopper 3. The microcontroller 5 controls the output shaft of the motor 435 to rotate, and the lower pulley 434 also rotates accordingly. Because the diameter of the upper pulley 434 is smaller than that of the lower pulley 434, a transmission effect can be formed, so the upper pulley 434 also rotates, driving the transmission shaft 431 to rotate. As the drive shaft 431 rotates, the first bevel gear 432 also rotates. Because the first bevel gear 432 meshes with the second bevel gear 433, the second bevel gear 433 also rotates, causing the shaft 41 to rotate. As the shaft 41 rotates, the agitator 421 also rotates. Since the outer end of the agitator 421 is located inside the limiting groove 422, the agitator 421 also moves along the trajectory of the limiting groove 422 when it rotates. When the agitator 421 moves to the right side of the feed hopper 3, it rotates and moves downwards simultaneously. When the agitator 421 rotates to the left side of the feed hopper 3... As it rotates, it moves upwards, repeating this process. It also moves up and down simultaneously, continuously agitating the slag inside the feed hopper 3, keeping it loose and effectively preventing slag accumulation at the feed inlet. As the shaft 41 continues to rotate, the scraper 423 also rotates, scraping the slag scattered on the bottom wall of the feed hopper 3 into the housing 1. At this time, as the lower pulley 434 rotates, the central shaft 441 also rotates, driving the spiral conveyor plate 442 to rotate. Through its own weight and the friction between the slag and the inner wall of the housing 1, the slag will move along... As the spiral conveyor plate 442 moves forward, it conveys the slag. The scraper 443 also rotates continuously with the spiral conveyor plate 442, scraping off the slag adhering to the inner wall of the shell 1. At the same time, as the central shaft 441 rotates, the gear 1 451 also rotates. Because the gear 1 451 is meshed with the gear 2 452, the gear 2 452 also rotates, driving the slag scraper 453 to rotate. The scraper teeth of different lengths on the surface of the slag scraper 453 can quickly scrape off the slag at the discharge port 2, preventing the slag from accumulating at the discharge port 2 and achieving the purpose of preventing blockage.

[0027] It is worth noting that the microcontroller 5 disclosed in the above embodiments is an S7-200 microcontroller, and the motor 435 is a YE3-90L-4 motor. The microcontroller 5 controls the operation of the motor 435 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
