Description

Technical Field

[0001] This utility model relates to the field of metallurgical and chemical equipment technology, and more specifically, to a cooling conveyor roller structure for high-titanium slag smelting products that can be rapidly cooled. Background Technology

[0002] High-titanium slag is a core raw material in the titanium industry. Its smelting products need to be rapidly cooled and stably transported before entering the subsequent crushing and sorting processes. As a key piece of equipment connecting smelting and post-processing, the cooling conveyor rollers directly affect the processing efficiency.

[0003] The currently common method involves pouring molten high-titanium slag into a fixed slag pan or shallow pit and relying on natural air cooling. This method has significant drawbacks. Due to the high temperature of the high-titanium slag, natural cooling takes tens of hours, severely restricting production pace and resulting in low site turnover. Furthermore, the slow cooling process easily leads to coarsening of the crystals within the high-titanium slag and may cause component segregation, affecting subsequent processing performance. Therefore, we propose a cooling conveyor roller structure for rapidly cooling high-titanium slag smelting products. Utility Model Content

[0004] The purpose of this invention is to provide a cooling conveyor roller structure for high-titanium slag smelting products that can be rapidly cooled, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cooling conveyor roller structure for rapidly cooling high-titanium slag smelting products includes an outer roller, which is composed of an inner cylinder and an outer cylinder fixedly installed outside the inner cylinder. A water-passing chamber for heat exchange and cooling is provided between the inner cylinder and the outer cylinder. A feed hopper connected to the interior of the inner cylinder is fixedly installed on the outer roller. A discharge hopper is fixedly installed at the discharge end of the outer roller. An inner heat-conducting roller is rotatably connected inside the inner cylinder. Spiral conveying blades are fixedly installed on the outer surface of the inner heat-conducting roller. A hollow shaft is fixedly installed at the input end of the inner heat-conducting roller. The hollow shaft is driven by a drive motor and gears. A heat exchange chamber is provided inside the hollow shaft. A cooling water pipe is provided at the water inlet end of the inner heat-conducting roller. An external discharge pipe is provided at the water outlet end of the hollow shaft.

[0007] Preferably, an inlet pipe connected to the water passage chamber is fixedly installed on the bottom cylinder of one side of the outer cylinder, and an outlet pipe connected to the water passage chamber is fixedly installed on the top cylinder of the other side of the outer cylinder.

[0008] This setting enables the normal flow of cooling water for heat exchange, achieving a cooling effect.

[0009] Preferably, the end of the inner heat-conducting roller near the cooling water pipe extends out of the outer roller and is rotatably connected to the outer roller, and the end of the outer roller near the hollow shaft is connected to the outside.

[0010] This feature allows the end cylinder of the outer roller to support the inner heat-conducting roller, making the inner heat-conducting roller more stable during rotation.

[0011] Preferably, the spiral conveyor blades are spiral-shaped, and the cooling water pipe and the inner heat-conducting roller, as well as the outer drain pipe and the hollow shaft, are rotatably connected by a sealed rotary joint.

[0012] This setting ensures that the cooling water pipes and external drain pipes do not affect the normal rotation of the hollow shaft.

[0013] Preferably, a plurality of water-blocking rings are fixedly installed on the wall of the heat exchange chamber, and a central hole is provided at the center of the water-blocking ring;

[0014] This design allows water to flow through the central hole between multiple baffle rings, ensuring that the heat exchange chamber always retains a sufficient amount of water for heat exchange operations.

[0015] Preferably, a driven gear is fixedly installed on the hollow shaft, and a driving gear is detachably installed at the end of the output shaft of the drive motor, with the driven gear and the driving gear meshing with each other.

[0016] Preferably, a mounting base is fixedly installed at the end of the output shaft of the drive motor, and the drive gear is detachably mounted on the side of the mounting base.

[0017] Preferably, both the hollow shaft and the output shaft of the drive motor are provided with bearing seats, and both the bearing seats and the drive motor are fixedly mounted on corresponding external frames.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model constructs a dual heat exchange system by setting a water-passing chamber between the inner and outer cylinders of the outer roller, in conjunction with the heat exchange chamber inside the inner heat-conducting roller, to replace the traditional natural cooling method, thereby achieving rapid cooling of molten high-titanium slag, significantly shortening the cooling time, and improving the production rhythm.

[0020] 2. This utility model, by setting spiral conveying blades on the outer side of the inner heat-conducting roller, can drive the high-titanium slag smelting product to move dynamically in the roller under the drive motor, avoiding uneven local heat dissipation caused by product accumulation; at the same time, the rapid cooling effect of dual heat exchange can suppress the coarsening of crystals inside the high-titanium slag, reduce the phenomenon of component segregation, and achieve the effect of ensuring the subsequent processing performance of high-titanium slag and improving product quality.

[0021] 3. This utility model achieves stable and coordinated operation of the cooling system and the conveying system by setting up the inlet and outlet pipes of the water passage chamber, the water baffle ring in the heat exchange chamber, and the sealed rotary joints between the cooling water pipe and the inner heat-conducting roller, and between the outer drain pipe and the hollow shaft. This ensures both continuous and efficient heat exchange and smooth and uninterrupted conveying, thereby reducing the risk of equipment failure and improving the overall operational stability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3This utility model provides a technical solution: a cooling conveyor roller structure for high-titanium slag smelting products that can be rapidly cooled, including an outer roller 1 fixedly installed on an external frame. The outer roller 1 consists of an inner cylinder 10 and an outer cylinder 11 fixedly installed outside the inner cylinder 10. A water-passing chamber 12 for heat exchange and cooling is provided between the inner cylinder 10 and the outer cylinder 11. The outer roller 1 provides a closed conveying space for the high-titanium slag smelting products. The water-passing chamber 12 can hold cooling water. Through heat exchange between the outer cylinder 11, the inner cylinder 10 and the product, the product temperature is initially reduced, laying the foundation for subsequent deep cooling.

[0030] In this embodiment, a feed hopper 15 connected to the interior of the inner cylinder 10 is fixedly installed on the outer roller 1, and a discharge hopper 16 is fixedly installed at the discharge end of the outer roller 1. The feed hopper 15 can guide the molten high-titanium slag to enter the inner cylinder 10 smoothly, avoiding splashing of high-temperature products; the discharge hopper 16 can centrally discharge the cooled products, prevent the products from scattering, and ensure that the cooling and conveying process is continuous and orderly.

[0031] Specifically, an inner heat-conducting roller 2 is rotatably connected inside the inner cylinder 10. A spiral conveying blade 21 is fixedly installed on the outer surface of the inner heat-conducting roller 2. A hollow shaft 25 is fixedly installed at the input end of the inner heat-conducting roller 2. The hollow shaft 25 is driven by a drive motor 29 and gears. The inner heat-conducting roller 2 can transfer its own heat to the product to accelerate cooling. When the spiral conveying blade 21 rotates, it can push the product to move along the length of the inner cylinder 10, avoiding product accumulation and uneven local heat dissipation, and achieving the synergistic effect of "conveying and cooling at the same time". A heat exchange chamber 20 is set inside the hollow shaft 25. A cooling water pipe 24 is set at the water inlet end of the inner heat-conducting roller 2, and an external drain pipe 26 is set at the water outlet end of the hollow shaft 25. Cooling water is introduced into the heat exchange chamber 20 through the cooling water pipe 24 to absorb the heat obtained by the inner heat-conducting roller 2 from the product, and then discharged through the external drain pipe 26 to form an internal circulation cooling, which enhances the heat conduction and cooling capacity of the inner heat-conducting roller 2.

[0032] Furthermore, a water inlet pipe 13 connected to the water passage chamber 12 is fixedly installed on the bottom cylinder of one side of the outer cylinder 11, and a water outlet pipe 14 connected to the water passage chamber 12 is fixedly installed on the top cylinder of the other side of the outer cylinder 11. The water inlet pipe 13 continuously injects low-temperature cooling water into the water passage chamber 12, and the water outlet pipe 14 promptly discharges the warm water after heat absorption. The water after heat exchange can be supplied to the outside for use, realizing the circulation of cooling water, avoiding the rise of water temperature in the water passage chamber 12 from affecting the heat exchange efficiency, and ensuring the continuous cooling effect of the outer roller 1.

[0033] In addition, the end of the inner heat-conducting roller 2 near the cooling water pipe 24 extends through the outer roller 1 and is rotatably connected to the outer roller 1. The end of the outer roller 1 near the hollow shaft 25 is connected to the outside. The end of the outer roller 1 can provide radial support for the inner heat-conducting roller 2 to prevent the inner heat-conducting roller 2 from shaking or deviating when rotating at high speed, and to ensure that the spiral conveying blades 21 can stably push the product to move.

[0034] like Figure 1 As shown, the spiral conveyor blades 21 are spiral in shape. The cooling water pipe 24 and the inner heat-conducting roller 2, as well as the outer drain pipe 26 and the hollow shaft 25, are rotatably connected by a sealed rotary joint 27. The sealed rotary joint 27 allows the inner heat-conducting roller 2 and the hollow shaft 25 to rotate freely while ensuring smooth flow of cooling water, thus preventing the cooling water pipe 24 and the outer drain pipe 26 from being entangled or pulled due to the rotation of the rollers and ensuring the normal operation of the equipment.

[0035] like Figure 1 and Figure 3 As shown, multiple water-blocking rings 22 are fixedly installed on the wall of the heat exchange chamber 20. A central hole 23 is provided at the center of the water-blocking ring 22. The water-blocking ring 22 can slow down the flow speed of cooling water in the heat exchange chamber 20, so that the water flows slowly between the water-blocking rings 22 and through the central hole 23, ensuring that there is always a sufficient amount of cooling water in the heat exchange chamber 20, maximizing the contact area between the cooling water and the wall of the heat exchange chamber 20, and improving the heat exchange efficiency.

[0036] like Figure 1 As shown, a driven gear 28 is fixedly installed on the hollow shaft 25, and a driving gear 292 is detachably installed at the end of the output shaft of the drive motor 29. The driven gear 28 and the driving gear 292 mesh with each other. The drive motor 29 drives the driving gear 292 to rotate, and through gear meshing, drives the driven gear 28 to rotate synchronously with the hollow shaft 25, thereby driving the inner heat-conducting roller 2 and the spiral conveying blade 21 to rotate, providing stable power for conveying and cooling.

[0037] like Figure 1 As shown, a mounting base 291 is fixedly installed at the end of the output shaft of the drive motor 29. The drive gear 292 is detachably mounted on the side of the mounting base 291 by multiple fastening bolts. When the drive gear 292 is worn, it can be directly disassembled and replaced without replacing the entire drive motor 29, thus reducing equipment maintenance costs and repair difficulty.

[0038] like Figure 1 As shown, both the hollow shaft 25 and the output shaft of the drive motor 29 are provided with bearing seats 293. The bearing seats 293 and the drive motor 29 are fixedly installed on the corresponding external frame. The bearing seats 293 can provide stable support for the output shafts of the hollow shaft 25 and the drive motor 29 respectively, reduce the frictional resistance when the shaft rotates, and improve the overall operating stability of the equipment.

[0039] Finally, it should be noted that the drive motor 29, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0040] When using the cooling conveyor roller structure for high-titanium slag smelting products that can be rapidly cooled, the inlet pipe 13 and the cooling water pipe 24 are connected to the external water source pipeline, and the outlet pipe 14 and the external drain pipe 26 are connected to the external water pipeline. The drive motor 29 is started, and the drive gear 292 meshes with the driven gear 28 to drive the hollow shaft 25, the inner heat-conducting roller 2, and the spiral conveying blade 21 to rotate.

[0041] Molten high-titanium slag is poured from the feed hopper 15 into the inner cylinder 10. The spiral conveyor blades 21 push the product to move. Cooling water in the water chamber 12 flows in through the inlet pipe 13 and is discharged through the outlet pipe 14. It is cooled by heat exchange through the inner cylinder 10. The cooling water pipe 24 supplies water to the heat exchange chamber 20. The water baffle ring 22 slows down the water flow speed to improve heat exchange. After absorbing heat, it is discharged from the outer drain pipe 26. After cooling, the product is discharged from the unloading hopper 16, realizing rapid cooling operation.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
