Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] As attached Figure 1 To be continued Figure 5 As shown:
[0030] A chain plate type dry slag conveyor includes a conveying box 1. A drive shaft 2 is rotatably connected to one end of the conveying box 1. A drive sprocket 3 is fixedly sleeved on the outer wall of the drive shaft 2. A driven shaft 4 is rotatably connected to the other end of the conveying box 1. A driven sprocket 5 is fixedly sleeved on the outer wall of the driven shaft 4. A chain 6 is sleeved on the outer wall of the drive sprocket 3 and the driven sprocket 5. A chain plate structure 8 is fixedly connected to the outer wall of the chain 6. There are multiple chain plate structures 8. The multiple chain plate structures 8 are arranged at equal intervals along the outer wall of an automatic cleaning structure 9. The automatic cleaning structure 9 is fixedly installed on the outer wall of the chain plate structure 8.
[0031] As attached Figure 4 To be continued Figure 5 As shown, multiple chain plate structures 8 are arranged in an inverted fish scale pattern, overlapping each other. Each chain plate structure 8 includes a connector 801, which is fixedly connected to the chain 6. A conveyor plate 802 is fixedly installed on the outer wall of the connector 801. Limiting plates 803 are fixedly installed on both sides of the conveyor plate 802. Multiple connectors 801 overlap each other, and the limiting plates 803 are inclined and overlap each other.
[0032] In the above technical solution, through the design of the chain plate structure 8, multiple chain plate structures 8 are arranged in an inverted fish scale pattern by overlapping each other, which can reduce the gaps between the chain plate structures 8 and reduce the leakage of fine dust from the gaps.
[0033] As attached Figure 4 To be continued Figure 7 As shown, the automatic cleaning structure 9 includes a baffle 901, which is fixedly connected to the conveyor plate 802. The baffle 901 is located between the limiting plates 803. A hinge 902 is fixedly installed on one side of the baffle 901, and a cleaning plate 903 is fixedly installed on the outer wall of the hinge 902.
[0034] In the above technical solution, through the design of the automatic cleaning structure 9, the automatic cleaning structure 9 is installed on the outer wall of the chain plate structure 8. When the conveyor plate 802 is in the return stroke, the cleaning plate 903 automatically hangs down to the lower part of the hinge 902 due to gravity, which can sweep the accumulated dust at the bottom of the conveyor box 1 to the tail of the conveyor box 1 and scrape it onto the conveyor plate 802; when the conveyor plate 802 is in the conveying stroke, the cleaning plate 903 automatically flips to the upper surface of the conveyor plate 802 due to gravity.
[0035] As attached Figure 1 As shown, one end of the conveying box 1 is inclined and the inclined end of the conveying box 1 is the output end. A discharge hopper 12 is fixedly installed at the output end of the conveying box 1. A slag storage bin 13 is provided at the bottom of the discharge hopper 12. An ash and slag cooling hopper 11 is provided at the other end of the conveying box 1. The ash and slag cooling hopper 11 is located directly above the conveying box 1.
[0036] As attached Figure 1 To be continued Figure 3 As shown, the chain 6 is a plate chain or a circular chain. Multiple equidistant support rollers 7 are fixedly installed on the inner wall of the conveyor box 1. The support rollers 7 are located below the chain 6 and are meshed with the chain 6.
[0037] In the above technical solution, through the design of chain 6 and support roller 7, chain 6 and support roller 7 adopt rolling friction, which has a high safety factor, low operation and maintenance workload, and ensures stable operation of dry slag conveyor without deviation or slippage.
[0038] As attached Figure 2 As shown, slag-blocking blocks 14 are fixedly installed on both sides of the inner wall of the conveyor box 1, and the slag-blocking blocks 14 are located above the chain plate structure 8.
[0039] In the above technical solution, the design of the slag-blocking block 14 prevents dry slag from falling into the gaps on both sides of the conveying box 1.
[0040] The specific usage and function of this embodiment are as follows:
[0041] When this utility model is in use, the dry slag falls into the conveying box 1 through the ash cooling hopper 11 and onto the upper surface of the chain plate structure 8. One end of the drive shaft 2 is connected to a motor, which drives the drive shaft 2 to rotate. The drive shaft 2 drives the drive sprocket 3 to rotate. The drive sprocket 3 drives the driven shaft 4 and the driven sprocket 5 to rotate through the chain 6. The chain 6 drives the chain plate structure 8 to move, and the dry slag is conveyed through the chain plate structure 8. Then it is discharged through the discharge hopper 12 and the discharged dry slag falls into the slag storage bin 13 for storage.
[0042] By designing the automatic cleaning structure 9, an automatic cleaning structure 9 is installed on the outer wall of the chain plate structure 8. When the conveyor plate 802 is on the return trip, the cleaning plate 903 automatically hangs down to the lower part of the hinge 902 due to gravity, which can sweep the accumulated dust at the bottom of the conveyor box 1 to the tail of the conveyor box 1 and scrape it onto the conveyor plate 802. When the conveyor plate 802 is on the conveying trip, the cleaning plate 903 automatically flips over to the upper surface of the conveyor plate 802 due to gravity.
[0043] Please refer to the above structure and process. Figure 1-7 .
