Description

Technical Field

[0001] The invention relates to the technical field of bottom slag transportation of power station boilers, and in particular to a slag accumulation processing device and method based on a slag scooping machine. Background Art

[0002] A thermal power plant, also known as a cogeneration plant, is a facility that produces both electricity and heat. It uses thermal energy conversion technology to convert chemical energy into thermal energy by burning coal, natural gas, heavy oil and other fuels in a boiler. The heat provided by these fuels is used to heat water and generate steam. After the coal is burned, coal ash and slag will accumulate at the bottom of the boiler, which needs to be cleaned up in time by a slag remover. In the slag after sintering, sulfides and acidic substances formed by coal with a high sulfur content will adhere to the scraper surface of the slag remover and corrode the scraper, resulting in a decrease in the strength and hardness of the scraper, reducing the service life of the scraper and increasing the cost of maintenance and replacement. Secondly, the accumulation of ash in the transmission chain will cause the chain to become stuck or damaged, accelerate the wear of the chain and increase the operating cost of the equipment. In response to the above problems, the inventors proposed a slag treatment device and method based on a slag remover to solve the above problems. Summary of the invention

[0022] 3. The present invention arranges an outer frame cleaning component. When the ash in the boiler falls into the loading plate, part of the ash will fall on the top of the conveying scraper and the lifting cleaning frame. After the conveying scraper is flipped 90°, part of the ash will fall directly. Some ash will still remain on the top of the conveying scraper and the lifting cleaning frame. When the conveying scraper passes through the cleaning roller, the cleaning roller rotates to remove the residual ash on the top of the lifting cleaning frame to avoid ash residue on the top of the lifting cleaning frame.

[0051] A motor 509 is fixedly provided on the inner wall of the side plate 2 away from the blanking frame 9, and the driving end of the motor 509 is connected to the driving shaft 501 through a pulley transmission group.

[0052] By adopting the above technical solution, the motor 509 drives the driving shaft 501 to rotate.

[0053] A method used by a slag accumulation processing device for a slag scooping machine comprises the following steps:

[0054] S1. First, turn on the motor 509 to drive the two transmission chains 504 to rotate synchronously clockwise. The transmission chain 504 rotates to push the ash at the bottom of the loading plate 3 upward to the unloading frame 9 through the conveying scraper 506. The ash is discharged through the unloading frame 9 to realize the transportation and transfer of the ash;

[0055] S2, after passing through the unloading frame 9, the conveying scraper 506 continues to move to the cleaning roller 802 under the guidance of the transmission chain 504, and the ash residue on the top of the conveying scraper 506 is cleaned by the rotation of the cleaning roller 802;

[0056] S3, when the two transmission chains 504 move to the chain cleaning assembly 7, the transmission chains 504 are clamped by two sets of cleaning brush heads 706 and reciprocatedly lifted and lowered to clean the ash and slag accumulated in the transmission chains 504;

[0057] S4, when the conveying scraper 506 moves to the bottom of the loading plate 3, the scraper cleaning brush 603 in the scraper self-cleaning assembly 6 is driven to move up and down reciprocatingly under the guidance of the guide frame 605 to clean the ash residue remaining on the outer wall of the conveying scraper 506 to ensure that the scraper surface is smooth;

[0058] S5. The ash and slag cleaned out by the conveying scraper 506 and the transmission chain 504 will fall into the storage frame in the base 1 for centralized collection.

[0059] By adopting the above technical solution, the slag remover can simultaneously clean the ash attached to the conveying scraper 506 and the transmission chain 504 during the process of conveying and transferring the accumulated slag.

[0060] Working principle: First, the motor 509 is controlled. The driving end of the motor 509 drives the driving shaft 501 to rotate clockwise through the pulley transmission group. The driving shaft 501 drives the corresponding meshing transmission chain 504 to rotate synchronously clockwise under the guidance of the guide wheel 503 through the two driving wheels 502. The two transmission chains 504 drive a number of conveying scrapers 506 to move synchronously to convey the ash and slag gathered on the top of the loading plate 3 upward to the unloading frame 9 in turn, and discharge it under the guidance of the unloading frame 9. After passing through the unloading frame 9, the conveying scraper 506 continues to move, flips 90° under the action of the transmission chain 504, and then moves vertically downward. When the conveying scraper 506 is turned over, the top end faces the cleaning roller 802. When the driving shaft 501 rotates, the driven shaft 801 is driven to rotate synchronously through the synchronous wheel transmission group. The driven shaft 801 drives the cleaning roller 802 to rotate synchronously. When the conveying scraper 506 passes the cleaning roller 802, the ash residue on the top of the conveying scraper 506 is cleaned by the cleaning roller 802. At the same time, the driving shaft 501 drives the transmission shaft 708 to rotate and the fixed column 709 to rotate synchronously through the first bevel gear 507 and the second bevel gear 508. The reciprocating lifting groove 710 provided in the fixed column 709 is a symmetrically distributed inverted V shape. The column 709 rotates through the fixed guide bolt 713 to drive the lifting cylinder 712 to perform periodic reciprocating lifting and lowering movements in the fixed cylinder 707 under the guidance of the reciprocating lifting groove 710. The lifting cylinder 712 drives the lifting plate 704 to synchronously reciprocate and lift under the guidance of the two guide rails 703 through the lifting rod 711. The lifting plate 704 drives two groups of cleaning brush heads to synchronously reciprocate and lift through the extension frames 705 on both sides. Each group of cleaning brush heads 706 is provided with two symmetrically distributed cleaning brush heads. The cleaning brush 706 wraps the transmission chain 504 and reciprocates to lift and lower the residual ash on the transmission chain 504 to clean it. 506 continues to move. When the conveying scraper 506 moves to the bottom of the loading plate 3, the guide groove 606 in the guide frame 605 below the loading plate 3 is set as a wave curve. When the conveying scraper 506 passes through this section of the guide groove 606, the guide column 604 drives the lifting cleaning frame 602 to move back and forth under the guidance of the guide groove 606. The lifting cleaning frame 602 moves back and forth through the reciprocating lifting movement of the lifting cleaning frame 602, driving the two scraper cleaning brushes 603 to move synchronously to clean the residual ash on the outer wall of the conveying scraper 506. The ash cleaned out of the conveying scraper 506 and the transmission chain 504 will fall into the storage frame for centralized collection.

The ash is discharged through the unloading frame (9) to realize the transportation and transfer of the ash; S2, after the conveying scraper (506) passes through the unloading frame (9), it continues to move to the cleaning roller (802) under the guidance of the transmission chain (504), and the ash residue on the top of the conveying scraper (506) is cleaned by the rotation of the cleaning roller (802); S3, when the two transmission chains (504) move to the chain cleaning assembly (7), the transmission chains (504) are clamped by two sets of cleaning brush heads (706) and moved up and down reciprocatingly to clean the ash and slag accumulated in the transmission chains (504); S4, when the conveying scraper (506) moves to the bottom of the loading plate (3), the scraper cleaning brush (603) in the scraper self-cleaning assembly (6) is driven to move up and down reciprocatingly under the guidance of the guide frame (605) to clean the ash residue remaining on the outer wall of the conveying scraper (506), so as to ensure that the scraper surface is smooth; S5. The ash and slag removed by the conveying scraper (506) and the transmission chain (504) will fall into the storage frame in the base (1) for centralized collection.
