Description

Technical Field

[0001] This utility model relates to the field of slag removal machine technology, specifically a novel die-forged chain slag removal machine. Background Technology

[0002] The die-forged chain slag remover is a device used to treat ash and slag produced after boiler combustion. Its working principle is that an electric motor or hydraulic motor transmits power to the drive wheel through a reducer. The drive wheel drives the die-forged chain to move. The scrapers fixed on the die-forged chain circulate in the tank, picking up the slag that falls into the tank. The die-forged chain slag remover is mainly used to separate solid materials that meet a certain particle size from liquid and solid mixtures. It is a continuous and efficient mechanical slag removal device.

[0003] In the long-term operation of current die-forged chain slag removal machines, the combined weight of the die-forged chain and scraper is relatively heavy, and the die-forged chain and scraper are not effectively supported during operation. As a result, the die-forged chain becomes loose due to elongation, which is not conducive to the stable operation of the die-forged chain. In addition, the frictional pressure between the scraper and the inner wall of the tank increases, which leads to the aggravated wear of the scraper. To address this, we propose a new type of die-forged chain slag removal machine. Utility Model Content

[0004] The purpose of this invention is to provide a novel forged chain slag remover, which effectively supports the forged chain and scraper during long-term operation, thereby effectively reducing the elongation of the forged chain, ensuring stable operation of the forged chain, and reducing scraper wear. This solves the problem that current forged chain slag removers, due to the combined weight of the forged chain and scraper and the lack of effective support during operation, cause the forged chain to elongate and loosen, hindering stable operation, and increasing frictional pressure between the scraper and the inner wall of the tank, leading to accelerated scraper wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel forged chain slag remover includes a trough and a forged chain. A drive sprocket is rotatably mounted on one side of the trough via a drive shaft, and a driven sprocket is rotatably mounted on the side of the trough opposite to the drive sprocket via a driven shaft. The drive sprocket and the driven sprocket are connected by a forged chain drive. Several scrapers are fixedly mounted at equal intervals on the outer surface of the forged chain. L-shaped rods are fixedly connected to the outer surfaces of the scrapers near both sides of the forged chain, and rollers are rotatably connected to the ends of the L-shaped rods. Annular track grooves are symmetrically fixedly mounted on both sides of the trough, and the rollers are located inside the annular track grooves.

[0006] Preferably, a drive motor is fixedly installed on the outer surface of the tank, and the output end of the drive motor is fixedly connected to the end of the drive shaft. The drive motor is a geared motor, which drives the drive sprocket to rotate through the drive shaft.

[0007] Preferably, a wear-resistant edge strip is fixedly installed at the edge of the outer surface of the scraper. The wear-resistant edge strip prevents wear on the edge of the scraper, thus avoiding the need to replace the scraper due to edge wear. Only the wear-resistant edge strip needs to be replaced, reducing the maintenance cost of the scraper.

[0008] Preferably, the inside of the tank is hollow, and the two sides of the tank are open.

[0009] Preferably, a plurality of fixing blocks are fixedly installed at equal intervals on the outer surface of the forging chain. A slot is provided on the outer surface of the fixing block opposite to the forging chain. An insert block is fixedly installed on the outer surface of the scraper, and the insert block is located inside the slot. Both the fixing block and the insert block have through holes on their outer surfaces. A pin is inserted into the through hole. When disassembling or replacing a damaged scraper, the pin inside the through hole is pulled out, and then the insert block and the slot are separated, so that the scraper can be removed. When installing the scraper, the insert block is inserted into the slot and the pin is inserted into the through hole, so as to facilitate the disassembly and replacement of the scraper.

[0010] Preferably, the outer surface of the pin is provided with annular grooves near both ends, and a retaining spring is provided inside the annular groove. The retaining spring inside the annular groove plays a limiting role in preventing the pin from slipping out of the through-hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a trough, a drive sprocket, a driven sprocket, a drive shaft, a driven shaft, a scraper, an L-shaped rod, rollers, and an annular track groove, achieves effective support for the forging chain and scraper during long-term operation of the forging chain slag remover. This effectively reduces the elongation of the forging chain, ensures stable operation of the forging chain, and reduces scraper wear. The drive sprocket drives the forging chain and driven sprocket to rotate, thereby causing the scraper to circulate within the trough, removing the slag that falls into the trough. During the reciprocating motion of the forging chain and scraper, the rollers located in the annular track groove provide effective support for the scraper and forging chain, effectively preventing the forging chain from elongating due to its own weight and that of the scraper. It also prevents the elongated forging chain from putting pressure on the scraper and increasing the frictional pressure between the scraper and the inner wall of the trough, thus effectively reducing scraper wear.

[0013] 2. By setting wear-resistant edge strips, this utility model avoids wear on the edge of the scraper, thus avoiding the need to replace the scraper due to edge wear. Only the wear-resistant edge strips need to be replaced, reducing the maintenance cost of the scraper.

[0014] 3. This utility model achieves the effect of facilitating the disassembly and replacement of the scraper by setting a fixing block, insert block, pin, through-hole, annular groove and retaining spring. When disassembling or replacing a damaged scraper, remove the retaining spring inside the annular groove and pull out the pin inside the through-hole, then separate the insert block and the slot to remove the scraper. When installing the scraper, insert the insert block into the slot, insert the pin into the through-hole, and snap the retaining spring into the annular groove. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-4As shown, this utility model proposes a novel forged chain slag remover, comprising a trough 1 and a forged chain 2. The trough 1 is hollow inside, with both sides open. A drive sprocket 7 is rotatably mounted on one side of the trough 1 via a drive shaft 10. A driven sprocket 6 is rotatably mounted on the side of the trough 1 opposite to the drive sprocket 7 via a driven shaft 8. The drive sprocket 7 and the driven sprocket 6 are connected by the forged chain 2. A drive motor 4 is fixedly mounted on the outer surface of the trough 1. The output end of the drive motor 4 is fixedly connected to the end of the drive shaft 10. The drive motor 4 is a geared motor, which drives the drive sprocket 7 to rotate via the drive shaft 10, thereby driving the forged chain 2 to rotate. The outer surface of the forged chain 2 is fixedly mounted with... The trough is equipped with several scrapers 3. The forging chain 2 drives the scrapers 3 to circulate in the trough 1 to remove the slag that falls into the trough 1. Wear-resistant edge strips 11 are fixedly installed at the edge of the outer surface of the scraper 3. The setting of the wear-resistant edge strips 11 avoids the wear of the edge of the scraper 3, thus avoiding the need to replace the scraper 3 due to edge wear. Only the wear-resistant edge strips 11 need to be replaced, which reduces the maintenance cost of the scraper 3. L-shaped rods 15 are fixedly connected to both sides of the outer surface of the scraper 3 near the forging chain 2, and rollers 14 are rotatably connected to the ends of the L-shaped rods 15. Annular track grooves 5 are symmetrically fixedly installed on both sides inside the trough 1, and the rollers 14 are located inside the annular track grooves 5.

[0024] In use, the driving sprocket 7 drives the forging chain 2 and the driven sprocket 6 to rotate, thereby causing the scraper 3 to circulate within the tank 1, scooping out the slag that falls into the tank 1. During the reciprocating motion of the forging chain 2 and the scraper 3, the roller 14 located in the annular track groove 5 provides effective support for the scraper 3 and the forging chain 2, effectively preventing the forging chain 2 from elongating due to its own weight and that of the scraper 3. It also prevents the elongated forging chain 2 from putting pressure on the scraper 3 and increasing the frictional pressure between the scraper 3 and the inner wall of the tank 1, thereby effectively reducing the wear of the scraper 3.

A slot 12 is provided on the side of the outer surface of the fixing block 9 away from the die-forged chain 2. An insert block 13 is fixedly installed on the outer surface of the scraper 3, and the insert block 13 is located inside the slot 12. Both the fixing block 9 and the insert block 13 are provided with through holes 19 on their outer surfaces. A pin 17 is inserted into the through hole 19. An annular groove 18 is provided on the outer surface of the pin 17 near both ends, and a retaining spring 16 is provided inside the annular groove 18.

[0027] In this embodiment, when disassembling or replacing the damaged scraper 3, the retaining spring 16 inside the annular groove 18 is removed and the pin 17 inside the through-hole 19 is pulled out, and then the insert block 13 and the slot 12 are separated, so that the scraper 3 can be disassembled. When installing the scraper 3, the insert block 13 is inserted into the slot 12, the pin 17 is inserted into the through-hole 19, and the retaining spring 16 is snapped into the annular groove 18.
