Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 and Figure 2 , the present invention provides a high-temperature conveyor, including a chassis 1. Both ends of the chassis 1 are provided with conveying ports. The chassis 1 can be applied in high-temperature equipment such as sintering machines, dryers, and heat treatment equipment as the installation foundation of the equipment.

[0024] The chassis 1 is evenly and rotatably installed with rollers 2, and the rollers 2 are horizontally distributed. Adjacent rollers 2 are connected and assembled through a transmission assembly 12. One of the rollers 2 is fixedly installed with a driven pulley 4; the transmission assembly 12 and the driven pulley 4 are both located outside the chassis 1 to avoid being affected by high temperatures. The driven pulley 4 is connected to an external speed reduction motor set (mainly including a motor, a gearbox, and a coupling) during use to generate driving power. The transmission assembly 12 can adopt a transmission method of sprockets and chains. Adjacent transmission assemblies 12 are arranged in a staggered manner and can be used to transmit power. In this way, all the rollers 2 can be rotated in the same direction at the same time, and the items placed on the upper side of the rollers 2 can be conveyed from one end to the other end inside the chassis 1.

[0025] Two sets of rollers 2 are provided with graphite covers 3. The graphite covers 3 have the properties of wear resistance and high temperature resistance, which can extend the service life of the rollers 2. One side of the chassis 1 is fixedly installed with an output pipe 11, and the other side of the chassis 1 is fixedly installed with an input pipe 5. The upper side of the output pipe 11 is connected and installed with a rotating seat 8 through a drain pipe. The upper side of the input pipe 5 is connected and installed with a rotating joint 7 through a drain pipe. The rotating joint 7 is connected and assembled with one end of the roller 2. The other end of the roller 2 passes through the rotating seat 8 and is provided with a clamping component 9. The clamping component 9 is installed with a heat exchange component 6, and the heat exchange component 6 is inserted into the roller 2. The rotating seat 8 is rotationally assembled with the circumferential side of the roller 2. The circumferential side of the roller 2 is evenly provided with through holes 10 for communicating with the rotating seat 8. The input pipe 5 is connected to an external cold medium input machine. During operation, the cold medium can be transported through the input pipe 5 and the rotating joint 7 to the roller 2. After cooling and heat exchange with the roller 2 and the graphite cover 3, the hot medium is discharged through the through holes 10, the rotating seat 8, and the output pipe 11. The settings of the rotating joint 7 and the rotating seat 8 can connect the heat exchange route without affecting the rotation of the roller 2.

[0026] The setting of the heat exchange component 6 is used to further improve the heat exchange capacity between the medium and the roller 2. In addition, the medium is input at one end port of the roller 2 and output at the through hole 10 at the other end. The outlet area is smaller, which can make the medium fully fill the roller 2 and ensure the heat exchange effect.

[0027] Specifically, please refer to Figure 5 , the clamping component 9 includes a flange ring 91 and a flange blind plate 92. The end of the roller 2 passing through the rotating seat 8 is fixedly installed with a flange ring 91. The flange ring 91 is connected and installed with a flange blind plate 92 through a bolt group. The end of the flange blind plate 92 close to the flange ring 91 is fixedly installed with a heat exchange component 6. The connection between the flange ring 91 and the flange blind plate 92 through the bolt group is convenient for disassembly and installation, so that the heat exchange component 6 can be conveniently replaced, with convenient maintenance and simple operation.

[0028] Specifically, please refer to Figure 3 , the heat exchange component 6 includes a spiral fin 61 and a support ring 62. At least two support rings 62 are evenly distributed in each roller 2. The spiral fin 61 is fixedly installed on the inner circumference of the support ring 62. One end of the spiral fin 61 away from the rotating joint 7 is fixedly assembled with the flange blind plate 92. The support ring 62 supports the spiral fin 61 to prevent the spiral fin 61 from deforming. The heat exchange component 6 can rotate with the roller 2. Due to the setting of the spiral fin 61, a conveying force along the axial direction of the roller 2 can be generated. This conveying force is opposite to the conveying direction of the cold medium, so it will increase the resistance to the conveying of the cold medium and is conducive to the heat exchange between the cold medium and the spiral fin 61.

[0029] Preferably, the spiral fins 61 are 2 to 3 distributed in a circumferential manner. Appropriately distributing the spiral fins 61 in a limited space can optimize the heat exchange effect.

[0030] Specifically, please refer toFigure 4 The graphite cover 3 includes an arc-shaped shell 31 and a limiting ring 32. A pair of limiting rings 32 are fixedly installed on each roller 2, and multiple pairs of arc-shaped shells 31 are sleeved on each roller 2. The arc-shaped shell 31 is made of graphite material, and each pair of arc-shaped shells 31 are connected and assembled by a bolt group. The arc-shaped shell 31 is located between the limiting rings 32. The limiting ring 32 is used to limit the axial position of multiple pairs of arc-shaped shells 31 to prevent axial movement. The arc-shaped shell 31 connected and installed by the bolt group can be easily replaced individually when damaged, reducing the maintenance cost.

[0031] A pair of limiting ribs 13 are fixedly installed on the circumferential side of each roller 2, and the arc-shaped shell 31 is provided with a groove for inserting the limiting rib 13. The insertion of the limiting rib 13 and the groove can ensure the transmission of torque, enabling the arc-shaped shell 31 to rotate with the roller 2 and avoiding the loss of conveying power.

[0032] Specifically, please refer to Figure 5 The rotating seat 8 includes an upper seat body 81 and a lower seat body 83 that are snap-fitted. Chambers are provided inside both the upper seat body 81 and the lower seat body 83. The chamber inside the lower seat body 83 is communicated with the discharge pipe on the upper side of the output pipe 11. A pair of rotary seals 82 are installed on the circumferential side of the roller 2, and the rotary seals 82 are respectively located on both sides of the through hole 10. The upper seat body 81 and the lower seat body 83 are both provided with grooves for installing the rotary seals 82. The upper seat body 81, the lower seat body 83, and the rotary seals 82 can seal the chamber, and the roller 2 can still rotate. The hot medium heat-exchanged inside the roller 2 is discharged from the through hole 10 and then enters the output pipe 11 along the chamber.

[0033] The working principle of this embodiment:

[0034] The input pipe 5 is connected to the external cold medium input machinery in the following ways:

[0035] In the first way, when using air as the cold medium, the input pipe 5 is connected to an external fan, and the output pipe 11 is connected to the outside through an exhaust duct.

[0036] In the second way, when using water as the cold medium, the input pipe 5 is connected to an external water supply system (including a storage water tank, a refrigerator, a pump, etc.), and the output pipe 11 is connected to the external water supply system through a pipeline to realize the recycling of water.

[0037] During operation, the external speed reduction motor group rotates one of the rollers 2 through the driven pulley 4, drives all the rollers 2 to rotate clockwise (with Figure 1 the direction as a reference) through the transmission assembly 12, conveys the items placed on the upper side from one end to the other end inside the chassis 1 through the graphite cover 3, completes the heat treatment during the process, and at the same time, the heat exchange element 6 inside the roller 2 also rotates clockwise, and the spiral fin 61 generates a backward conveying force.

[0038] The cold medium enters the roller 2 through the input pipe 5 and the rotary joint 7. After exchanging heat with the heat exchange element 6, the roller 2 and the graphite cover 3, it then enters the output pipe 11 through the through hole 10 and the rotary seat 8 and is discharged.

[0039] After long-term use, the heat exchange element 6 can be disassembled through the clamping component 9 for maintenance or replacement to ensure the heat exchange capacity. When a part of the graphite cover 3 is damaged, the corresponding arc-shaped shell 31 can be replaced.
