Description

Technical Field

[0001] This utility model relates to the technical field of scraper slag removers, specifically a forged chain for a scraper slag remover. Background Technology

[0002] A scraper slag remover is a device used to separate solid substances of a certain particle size from a liquid-solid mixture. It is often used in sorting or solid-liquid separation applications. It mainly uses scrapers installed on a directional moving forging chain to discharge ash and slag from the bottom water tank of the furnace. It is a continuous and efficient mechanical slag removal device.

[0003] Currently, in the operation of scraper slag removers, the scrapers on the forged chain are usually flat plates. When the scraper scrapes the slag inside the tank, the uneven distribution of slag inside the tank will cause uneven force on the flat scraper, which will make the scraper prone to deformation. At the same time, it will also cause uneven force on the forged chain, which will accelerate the wear of the forged chain and reduce its service life. To address this, we propose a forged chain for scraper slag removers. Utility Model Content

[0004] The purpose of this utility model is to provide a forged chain for a scraper slag remover. When the scraper pushes the slag inside the tank, the slag inside the tank gathers towards the forged chain, which helps to balance the force on the forged chain and scraper, avoids scraper deformation and accelerated wear of the forged chain, and extends the service life of the scraper and forged chain. This solves the problem that in current scraper slag removers, the scrapers on the forged chain are usually flat plates. When the scraper scrapes the slag inside the tank, the uneven distribution of slag leads to uneven force on the flat scraper, causing it to deform easily. This also leads to uneven force on the forged chain, resulting in accelerated wear and reduced service life of the forged chain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forged chain for a scraper slag remover, comprising a pin, a chain plate, and a V-shaped scraper. A notch is provided on the outer surface of the chain plate near one end, and rotating insertion holes are provided on the outer surface of the chain plate near both ends, through which the pin passes. A cross plate is fixedly installed on the outer surface of the chain plate, a fixing plate is fixedly installed on the upper surface of the cross plate, and a V-shaped scraper is fixedly installed on the upper surface of the fixing plate.

[0006] Preferably, the outer surface of the V-shaped scraper is provided with a wear-resistant and smooth coating. When the slag is pushed towards the chain plate by the V-shaped scraper, the wear-resistant and smooth coating facilitates the flow of the slag and also avoids wear on the V-shaped scraper, thus extending the service life of the V-shaped scraper.

[0007] Preferably, a reinforcing plate is fixedly installed on the upper surface of the fixed plate, and the reinforcing plate is fixedly connected to the outer surface of the V-shaped scraper. The reinforcing plate can improve the stress strength of the V-shaped scraper to avoid deformation of the V-shaped scraper.

[0008] Preferably, a groove is provided at the middle position of the lower surface of the horizontal plate, and the chain plate is located inside the groove, which increases the contact area between the horizontal plate and the chain plate, and at the same time plays a limiting role for the horizontal plate, thereby improving the firmness between the horizontal plate and the chain plate.

[0009] Preferably, a fixing block is fixedly installed at the middle position of the lower surface of the fixing plate, and a fixing socket is provided at the middle position of the upper surface of the horizontal plate, with the fixing block located inside the fixing socket. Both the outer surfaces of the horizontal plate and the fixing block are provided with through pin holes, and a pin is provided inside the through pin holes. The V-shaped scraper is detachably connected to the horizontal plate through the fixing socket, the fixing block, the through pin holes, and the pin, which facilitates the disassembly, assembly, and replacement of the V-shaped scraper.

[0010] Preferably, a limiting block is provided at one end of the pin, and an annular groove is provided on the side of the outer surface of the pin away from the limiting block. A retaining spring is provided inside the annular groove, and a retaining ring is slidably sleeved on the outer surface of the pin near the retaining spring. The movement of the pin is restricted by the limiting block, the annular groove, the retaining spring, and the retaining ring to prevent the pin from slipping out of the through pin hole.

[0011] Preferably, auxiliary plugs are fixedly installed on the lower surface of the fixed plate near both ends, and auxiliary sockets are provided on the upper surface of the horizontal plate near both ends. The two auxiliary plugs are located inside the two auxiliary sockets respectively. The setting of auxiliary sockets and auxiliary plugs can improve the stability and stress strength of the fixed plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting chain plates, notches, pins, rotating insertion holes, fixing plates, horizontal plates, and V-shaped scrapers, achieves the effect of causing the slag inside the tank to gather towards the forging chain when the scraper pushes it. This facilitates a more balanced force on the forging chain and scraper, avoids scraper deformation and accelerated wear of the forging chain, and extends the service life of the scraper and forging chain. The chain plates are rotatably connected end to end by pins to form a forging chain. The forging chain drives the V-shaped scraper to reciprocate to scrape away the slag inside the tank. When the V-shaped scraper pushes the slag inside the tank, the slag gathers towards the forging chain, making the force on the forging chain and V-shaped scraper more balanced, avoiding V-shaped scraper deformation and accelerated wear of the forging chain, and extending the service life of the V-shaped scraper and forging chain.

[0014] 2. By setting a wear-resistant and smooth coating layer, the slag gathers towards the chain plate under the push of the V-shaped scraper. The wear-resistant and smooth coating layer facilitates the flow of slag and avoids wear on the V-shaped scraper, thus extending the service life of the V-shaped scraper.

[0015] 3. This utility model achieves the effect of facilitating the installation and removal of V-shaped scrapers by setting up a fixed insertion port, a fixed insertion block, a through pin hole, a pin, a limiting block, an annular groove, a retaining spring, and a retaining ring. When installing the V-shaped scraper, insert the fixed insertion block into the fixed insertion port, then insert the pin into the through pin hole, and then put the retaining ring on the pin. The limiting block and the retaining ring are located on the outer sides of the horizontal plate, respectively. The retaining spring is inserted into the annular groove to limit the retaining ring, thus completing the installation of the V-shaped scraper. When removing the V-shaped scraper, the operation is the reverse. Attached Figure Description

When the chain plates 2 are rotatably connected by the pin 1, one end of each adjacent chain plate 2 is inserted into the notch 10. Rotary insertion holes 5 are provided near both ends of the outer surface of the chain plates 2, through which the pin 1 passes. A horizontal plate 6 is fixedly mounted on the outer surface of the chain plates 2. A groove 11 is provided in the middle of the lower surface of the horizontal plate 6, and the chain plates 2 are located inside the groove 11, thus increasing the contact area between the horizontal plate 6 and the chain plates 2, and simultaneously limiting the movement of the horizontal plate 6. The stability between the horizontal plate 6 and the chain plate 2 is improved. A fixing plate 14 is fixedly installed on the upper surface of the horizontal plate 6, and a V-shaped scraper 3 is fixedly installed on the upper surface of the fixing plate 14. The outer surface of the V-shaped scraper 3 is provided with a wear-resistant and smooth coating 15. When the slag is pushed towards the chain plate 2 by the V-shaped scraper 3, the wear-resistant and smooth coating layer 15 facilitates the flow of slag and also avoids wear on the V-shaped scraper 3, extending the service life of the V-shaped scraper 3. A reinforcing plate 16 is fixedly installed on the upper surface of the fixing plate 14, and the reinforcing plate 16 is fixedly connected to the outer surface of the V-shaped scraper 3.

[0024] In use, the chain plates 2 are rotatably connected at both ends by a pin 1 to form a forging chain. The forging chain drives the V-shaped scraper 3 to reciprocate to scrape away slag and other materials inside the tank. When the V-shaped scraper 3 pushes the slag inside the tank, the slag will gather towards the forging chain, making the force on the forging chain and the V-shaped scraper 3 more balanced, avoiding deformation of the V-shaped scraper 3 and accelerated wear of the forging chain, thus extending the service life of the V-shaped scraper 3 and the forging chain.

Both the outer surfaces of the horizontal plate 6 and the fixing block 12 are provided with through pin holes 9, and pins 4 are provided inside the through pin holes 9. One end of the pin 4 is provided with a limit block 20, and the outer surface of the pin 4 is away from the limit block 20. An annular groove 17 is provided on one side, and a retaining spring 18 is provided inside the annular groove 17. A retaining ring 19 is slidably sleeved on the outer surface of the pin 4 near the retaining spring 18. An auxiliary plug 13 is fixedly installed on the lower surface of the fixing plate 14 near both ends. An auxiliary socket 7 is provided on the upper surface of the horizontal plate 6 near both ends, and the two auxiliary plugs 13 are respectively located inside the two auxiliary sockets 7. The setting of the auxiliary sockets 7 and the auxiliary plugs 13 can improve the stability and stress strength of the fixing plate 14.
