Description

Technical Field

[0001] This utility model relates to the technical field of mesh belt furnaces, and in particular to a mesh belt return device for mesh belt furnaces. Background Technology

[0002] Mesh belt sintering furnaces use a mesh belt as a carrier to transport products into the heating zone. The mesh belt requires a return drive device, so a return device needs to be installed at the bottom of the sintering furnace. With industry development, the control of product production costs is becoming increasingly stringent. This is reflected in sintering furnaces where the amount of product to be sintered per unit length of mesh belt has increased, whereas previously sintering furnaces used mesh belt troughs as the load-bearing structure for the mesh belt return.

[0003] However, as the load increases, it is necessary to reduce resistance at various points, because the driving friction cannot be increased indefinitely. For example... Figures 1-2 As shown, the existing mesh belt sintering furnace using mesh belt troughs 400 for transportation has the following defects: 1. Due to gravity, the mesh belt is in contact with the mesh belt trough 400 throughout the entire process. Since the mesh belt trough 400 and the furnace itself are of the same length, the friction from the entire mesh belt is very high. This friction leads to two consequences: severe wear on the mesh belt and excessive force on the drive rollers. When the force exceeds the friction of the drive rollers, the drive rollers will slip, causing instability in the mesh belt's movement. 2. Due to the long length of the furnace, it is impossible to make the mesh belt trough 400 from a single piece of plate; it must be made in sections. As a woven structure, the mesh belt's pores easily catch on the starting edges at the joints, leading to abnormal conveying. 3. Since the return mesh belt trough 400 is generally slightly higher than the ground, and the mesh belt trough 400 is made of plate, two problems arise: the bottom of the mesh belt trough 400 is difficult to clean, and the wider the mesh belt, the more serious the problem; if products fall below the mesh belt, they will get stuck or be carried by the mesh belt to the transmission components, causing furnace jamming. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a mesh belt return device for a mesh belt furnace, which uses a rotatable roller to transport the heated mesh belt. The two are in a rolling friction form with low friction, which significantly reduces friction, reduces wear, extends the life of the mesh belt, reduces the cost of use, and improves the conveying efficiency of the mesh belt.

[0006] (II) Technical Solution

[0007] The solution adopted by this utility model to solve the above-mentioned technical problems is a mesh belt return device for a mesh belt furnace, including a mesh belt furnace body, wherein the mesh belt furnace body is provided with a furnace chamber for conveying mesh belts along its length direction; a mesh belt return device is provided below the mesh belt furnace body, the mesh belt return device is arranged along the mesh belt conveying direction in the furnace chamber, and the mesh belt return device includes a plurality of rollers arranged at intervals along the mesh belt conveying direction, the rollers being able to rotate around an axis perpendicular to the mesh belt conveying direction to convey the mesh belt.

[0008] The above solution uses rotatable rollers to convey the heated mesh belt. The two are in a rolling friction form with low friction, which significantly reduces friction, reduces wear, extends the life of the mesh belt, and lowers the operating cost. At the same time, it improves the conveying efficiency of the mesh belt. In addition, the rollers are arranged at intervals and the whole is a rolling structure, which avoids the problem of the mesh belt getting caught due to the edge turning or deformation of the traditional mesh belt trough, thus reducing operational failures.

[0009] In some embodiments, the length direction of the roller is perpendicular to the direction of the conveyor belt, ensuring that the roller can evenly support the conveyor belt, preventing the conveyor belt from running off-center or experiencing excessive local stress, and improving the stability and uniformity of the conveyor belt operation.

[0010] In some embodiments, a fixed base is provided below the main body of the mesh belt furnace, and the two ends of the roller body located in its length direction are fixed to the fixed base by fixed angle steel; and the roller body is fixed to the fixed angle steel by fixed screws, and a bearing is provided between the roller body and the fixed screws to realize the rotational movement of the roller body.

[0011] By adopting the above solution, the combination design of fixed seat, fixed angle steel and bearing makes the installation of the roller more stable and the rotation smoother, reducing vibration and noise during operation, while also facilitating disassembly and maintenance.

[0012] In some embodiments, a sealing structure is provided between the roller and the bearing.

[0013] By adopting the above solution, the sealing structure can effectively prevent dust or impurities from entering the bearing, avoid bearing jamming or wear, ensure stable rotational performance of the roller, and extend the service life of the bearing and roller.

[0014] In some embodiments, the rollers are arranged at equal intervals along the conveying direction of the mesh belt, and the distance between every two rollers is 0.5 meters.

[0015] The above scheme, with rollers arranged at equal intervals, provides uniform support for the conveyor belt, preventing it from sagging or deforming due to insufficient support. Furthermore, the larger spacing between the rollers facilitates cleaning and maintenance, and products falling below the conveyor belt will land directly on the ground and will not enter the drive system with the conveyor belt, thus avoiding blockage or damage to the drive components.

[0016] In some embodiments, the outer surface of the roller body is provided with a wear-resistant coating to enhance the service life of the roller body.

[0039] like Figures 3-6As shown, this utility model provides a mesh belt return device for a mesh belt furnace, including a mesh belt furnace body 100. The mesh belt furnace body 100 has a furnace chamber 101 for conveying mesh belt 300 along its length direction. A mesh belt return device 200 is arranged below the mesh belt furnace body 100. The mesh belt return device 200 is arranged along the conveying direction of the mesh belt 300 in the furnace chamber 101. The mesh belt return device 200 includes a plurality of rollers 201 arranged at intervals along the conveying direction of the mesh belt 300. The rollers 201 are capable of rotating around an axis perpendicular to the conveying direction of the mesh belt 300 to convey the mesh belt 300. The above solution uses rotatable rollers 201 to convey the heated mesh belt 300. The two are in a rolling friction form with low friction, which significantly reduces friction, reduces wear, extends the life of the mesh belt 300, and lowers the operating cost. At the same time, it improves the conveying efficiency of the mesh belt 300. In addition, the rollers 201 are arranged at intervals and the whole is a rolling structure, which avoids the problem of the mesh belt 300 getting caught due to the flange or deformation of the groove in the traditional mesh belt 300, thus reducing operational failures.

[0040] In some embodiments, the length direction of the roller 201 is perpendicular to the conveying direction of the mesh belt 300, ensuring that the roller 201 can evenly support the mesh belt 300, preventing the mesh belt 300 from deviating or experiencing excessive local stress, and improving the stability and uniformity of the mesh belt 300's operation. In some embodiments, a fixed base 102 is provided below the mesh belt furnace body 100, and the two ends of the roller 201 located in its length direction are fixed to the fixed base 102 by fixed angle steel 202; furthermore, the roller 201 is fixed to the fixed angle steel 202 by fixed screws 203, and a bearing 204 is provided between the roller 201 and the fixed screws 203 to realize the rotational movement of the roller 201. Using the above scheme, through the combined design of the fixed base 102, fixed angle steel 202, and bearing 204, the installation of the roller 201 is more stable, and the rotational movement is smoother, reducing vibration and noise during operation, while facilitating disassembly and maintenance. In some embodiments, a sealing structure is provided between the roller 201 and the bearing 204. By adopting the above solution, the sealing structure can effectively prevent dust or impurities from entering the bearing 204, avoid the bearing 204 from jamming or wearing, ensure the stable rotation performance of the roller body 201, and extend the service life of the bearing 204 and the roller body 201.
