Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a conveying chain structure and a horizontal single-chain scraper conveyor. Background Art

[0002] After sludge is dried, it is usually incinerated with domestic waste. The moisture content of the dried sludge is 40±5%. To transfer the dried sludge from the dryer outlet to the garbage feed outlet, a conveying device needs to be selected. The horizontal single-chain conveyor scraper is one of the conveying devices. The horizontal single-chain conveyor scraper is a continuous conveying device that conveys powder, small particles, small blocks and other bulk materials in a closed rectangular cross-section shell with the help of a moving scraper chain. The device can convey materials horizontally or tilted within an angle range of 0-60°.

[0003] The chain in the existing horizontal single chain conveyor scraper is generally connected with a scraper 8, such as Figure 1 and Figure 2 As shown, the scraper 8 is driven by the chain movement to push or scrape the sludge. The return end face of the scraper 8 directly contacts the guide rail and moves frictionally. After long-term use, the resistance of the chain return will become larger. After a period of operation, grooves will be worn on the scraper end face and the guide rail will also be worn and thinned, resulting in a shortened service life of the return guide rail. Utility Model Content

[0004] The utility model aims at the deficiencies in the prior art and provides a conveying chain structure and a horizontal single-chain scraper conveyor.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] The beneficial effect of adopting the above technical solution is that the walking roller group rolls on the return guide rail as the conveying chain link moves, so as to reduce the return resistance, reduce the operating load, reduce wear, and extend the service life of the return guide rail and the scraper.

[0009] Furthermore, the walking roller group includes a roller, a pin and a wheel group bracket, the roller is installed on the wheel group bracket through the pin, the roller rotates around the pin, the roller contacts the return guide rail and rotates on the return guide rail, rotating with the movement of the conveying chain segment, and the wheel group bracket is installed on the wing plate of the conveying chain segment.

[0011] Furthermore, a rib plate is connected to one side of the wing plate close to the wheel set bracket.

[0012] The beneficial effect of adopting the above technical solution is: the strength of the wing plate is improved by the rib plate, so as to prevent the wing plate from being damaged, deformed or broken due to long-term use.

[0013] Furthermore, the scraper is made of high molecular weight polyethylene material. Since high molecular weight polyethylene material has high wear resistance and corrosion resistance, the service life of the scraper can be extended.

[0014] Furthermore, the traction chain section has the same traction structure as the conveying chain section, and the traction chain section includes a chain sleeve, and Z-shaped chain plates are respectively welded at both ends of the chain sleeve. Two ends of the two Z-shaped chain plates away from the chain sleeve are respectively provided with mounting holes, and the axes of the two mounting holes coincide.

The split sprocket is easy to repair and replace, saving time, reducing workload and improving maintenance efficiency; while the traditional design sprocket is integrated and directly installed on the shaft. When the wheel socket is worn, the entire bearing and bearing seat related to the shaft need to be dismantled and disassembled, and the equipment needs to be lifted away for maintenance, which requires a large workload and a long maintenance time.

[0020] Furthermore, the split sprocket assembly includes a split sprocket, a hub sleeve, a pressure plate, and a sleeve top screw. The head main shaft and the tail driven shaft are provided with shoulders for positioning the hub sleeve.
