[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This application discloses a chain conveyor suitable for high-temperature environments. The chain conveyor features a modular design, such as... Figure 1 and Figure 2 As shown, the system includes a drive section unit with driving function, a conveyor section unit providing intermediate conveying function, and a driven section unit with driven function. The drive section unit, conveyor section unit, and driven section unit are all arranged opposite each other on the left and right sides to form a conveying surface of a certain width. The units on both sides can be connected by tie rods. The drive mechanism 1, drive line 2, conveyor line 3, driven line 4, and driven mechanism 5 are connected sequentially to form a complete conveyor. Figure 3 , Figure 6 and Figure 7As shown, the drive line 2, conveyor line 3, and driven line 4, respectively located on both sides, each include side plates 6 arranged opposite each other on both sides. The side plates 6 are made of carbon steel sheet metal, which is easy to process and resistant to high temperatures. The load friction strip 7 is sandwiched between the opposite side plates 6. The load friction strip 7 has threaded holes and is connected to the corresponding reserved holes of the side plates 6 by bolts, thereby fixing the load friction strip 7 at the first height of the side plates 6. The load friction strip 7 is made of 45 steel and has a load groove adapted to the chain 8 to bear the load rolling friction of the chain 8 and ensure the stability of the chain operation. The load friction strip 7 can be spliced ​​in multiple sections to adapt to the length of the conveyor. The ends of the load friction strip 7 are beveled to ensure smooth transition of the chain 8. When adjacent load friction strips 7 are connected, a gap is left to ensure that the load friction strip meets the thermal barrier and cold shrinkage requirements of the load friction strip when the temperature changes in the high-temperature environment. The return plate 9 is sandwiched between the two opposite side plates 6. The return plate 9 is fixed at the second height of the side plate 6. The first height is higher than the second height. That is, the height of the load friction strip 7 relative to the side plate 6 is higher than the height of the return plate 9 relative to the side plate 6. The return plate 9 is made of stainless steel, which is maintenance-free and greatly reduces maintenance costs. It also has high temperature resistance. The chain 8 is made of carbon steel. The chain 8 is driven by the drive mechanism 1. After passing through the drive line 2, the conveyor line 3 and the driven line 4, it returns through the driven mechanism 5. The outgoing stage of the chain 8 is placed on the load friction strip 7. The return stage of the chain 8 is placed on the return plate 9 to support the chain 8 and prevent the return part of the chain from slackening. This allows the load on the conveying plane to run in the conveying direction of the chain 8. On the outermost side plates 6 on each side, guide friction strips 10 can be provided to guide the load. The guide friction strips 10 are extruded stainless steel strips with high surface strength, are maintenance-free, do not require additional coatings or surface treatments, and are suitable for high-temperature environments. The ends of the guide friction strips 10 are also beveled.

[0030] In some implementations, such as Figure 3 , Figure 6 and Figure 7 As shown, an oil receiving trough 11 with an oil receiving function is provided. The oil receiving trough 11 is a strip-shaped metal trough with an upward opening. The length direction of the oil receiving trough 11 is the conveying direction. The oil receiving trough 11 is sandwiched between the side plates 6 on both sides and located below the return plate 9. Its projected area is larger than that of the return plate 9 at the corresponding position. The lubricating oil on the chain 8 will flow downward to the return plate 9 under the action of gravity, and then flow down through the edge of the return plate 9 into the oil receiving trough 11 to prevent waste lubricating oil from polluting the working environment. The oil receiving trough 11 may be provided with an oil drain port, or the waste lubricating oil may be discharged by other means.

[0031] In some implementations, such as Figure 5As shown, the bottom side of the side plate 6 is provided with a first mounting groove 601, the corresponding position of the return plate 9 is provided with a second mounting groove 901, and the corresponding position of the oil receiving groove 11 is provided with a mounting hole 1101. The mounting hole 1101 passes through both sides of the oil receiving groove 11. The connecting mechanism detachably connects the side plate 6, the return plate 9, and the oil receiving groove 11. The connecting mechanism includes a double-ended screw 12 with internal and external threads, a nut 13, and a screw 14. The two ends of the double-ended screw 12 have external threads on the outer side and internal threads on the inner side. The nut 13 and the screw 14 can be screwed with the external threads and internal threads, respectively. The outer diameter of the head end of the double-ended screw 12 is smaller than the outer diameter of its middle section. The openings of the first mounting groove 601 and the second mounting groove 901 are both set downwards. The double-ended screw 12 with internal and external threads passes through the mounting holes 1101 on both sides of the oil receiving groove 11 and keeps its two ends outside the mounting holes 1101, thereby connecting with the oil receiving groove 11. 1. To complete the connection, the installation process can begin by fitting the nuts 13 at both ends. Then, pass one end through the corresponding mounting hole 1101 and slide it horizontally. Next, pass the other end through the corresponding mounting hole 1101. The opening of the first mounting groove 601 is placed between the screw 14 and the nut 13 at the end. The opening of the second mounting groove 901 is placed between the nut 13 and the rod. By tightening the nut 13 and the screw 14, the side plate 6 and the return plate 9 are clamped into the oil receiving groove 11, thus completing the fixed connection between the side plate 6, the return plate 9, and the oil receiving groove 11. If disassembly is required, loosen the screw 14 and the nut 13 to separate the three from the vertical height, which facilitates cleaning of the oil receiving groove 11 and replacement of the return plate 9. At the same time, the chain 8 can be replaced from the bottom of the conveyor without removing the load friction strip 7, ensuring structural stability and improving maintenance convenience.

[0032] In some implementations, such as Figure 3 and Figure 4 As shown, the drive mechanism 1 includes a motor 15, a drive wheel 16, a motor bracket 17, a transmission shaft 18, a transmission chain 19, and a head-end conveyor sprocket 29. The drive wheels 16 are respectively set on the side plates 6 of the drive mechanism 1 on both sides. The drive wheels 16 can rotate freely vertically. The drive wheels 16 on both sides are connected by the transmission shaft 18 to transmit power. The motor 15 is set below the drive line body 2 through the motor bracket 17. The head-end conveyor sprocket 29 is fixed on the side of the transmission shaft 18 near the sprocket of the motor 15. The motor 15 drives the head-end conveyor sprocket 29 to rotate through the transmission chain 19, thereby driving the drive wheel 16 to rotate through the transmission shaft 18. The transmission chain 19 is made of carbon steel. The chain 8 is wound around the drive wheel 16 to transmit power to the chain 8 and drive the chain 8 to move. The motor 15 and the drive wheel 16 are indirectly driven. The vertical distance of the motor 15 can be adjusted by adjusting the height of the motor bracket 17 to keep it away from the high temperature environment concentrated on the conveying surface, thereby improving the service life of the motor 15.

[0033] In some implementations, such as Figure 7 and Figure 8 As shown, the driven mechanism 5 includes a driven wheel 20, a tension wheel 21, and a tension adjustment mechanism 22. The driven wheel 20 and the tension wheel 21 are respectively disposed on the side plates 6 of the driven mechanism 5 on both sides. Both the driven wheel 20 and the tension wheel 21 can rotate freely vertically. The tension wheel 21 is positioned lower than the driven wheel. The tension wheel 21 is connected to the side plate 6 through the tension adjustment mechanism 22. The tension adjustment mechanism 22 can drive the tension wheel 21 to move up and down vertically. The chain 8 is wound around the driven wheel 20 and the tension wheel 21. The tension of the chain 8 can be adjusted through the tension adjustment mechanism 22.

[0034] In some implementations, such as Figure 6 and Figure 7 As shown, the oil receiving mechanism also includes an oil guide plate 23, which is a metal bent part with a downward bending direction. The oil guide plate 23 is placed at the joint of adjacent oil receiving tanks 11 to prevent waste lubricating oil from flowing into the gap between the contacting adjacent oil receiving tanks 11. The waste lubricating oil is guided into the oil receiving tank 11 by the slope, without polluting the working environment.

[0035] In some implementations, such as Figure 7 and Figure 9 As shown, the cleaning mechanism includes a connector and a brush head 24. The connector includes a brush head connecting part 25 and a side plate connecting part 26, which are integrally formed. The brush head 24 consists of several high-temperature resistant nylon filaments. One end of the high-temperature nylon filament is vertically inserted into the brush head connecting part 25 and fixed. The side plate 6 at the driven mechanism 5 has an opening 602. The shape of the opening 602 matches the shape of the brush head connecting part 25, ensuring that the brush head connecting part 25 can pass through. After the brush head connecting part 25 and the brush head 24 pass through the opening 602, the side plate connecting part 26 and the side plate 6 at the opening 602 can be detachably connected by bolts. At this time, the position of the brush head 24 abuts against the chain 8, and the brush head 24 generates friction against the running chain 8, thus achieving a cleaning effect.

[0036] In some implementations, such as Figure 9 As shown, the connector also has a lubricating oil channel 27 that runs through the brush head connector 25 and the side plate connector 26. The lubricating oil can be connected to the opening of the lubricating oil channel 27 in the side plate connector 26 through the lubricating oil nozzle, flow through the side plate connector 26 to the brush head connector 25, and flow through the brush head 24 to the chain 8, thus lubricating the chain 8. The brush head 24 and the connector are easy to disassemble and can be replaced from the outside of the line body in a timely manner without complicated disassembly, reducing maintenance costs and meeting high temperature resistance requirements.

[0037] In some implementations, such as Figures 1 to 10As shown, this conveyor features a modular design, allowing for the free assembly of several conveyor lines 3, drive lines 2, and driven lines 4 to adapt to various working conditions. The connection method involves adjacent side plates 6 along their length being connected via side plate connectors 28. Adjacent side plates 6 are spaced apart, as shown in the diagram. Figure 10 As shown, the side plate connector 28 has connecting holes 2801 and strip holes 2802 arranged laterally. The length direction of the strip holes 2802 is the conveying direction. Bolts pass through the connecting holes 2801 and strip holes 2802 respectively and are connected to the reserved holes of the corresponding side plates. Since there is a gap between the side plates 6, and the side plate connector 28 has strip holes 2802 to allow the bolts to move laterally, it can ensure that the thermal barrier of the side plates 6 can be met when the temperature changes in high and low temperature environments, thus ensuring the stability of the overall structure.
