Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag treatment technology, specifically to a water-cooled rolling mill roller for treating high-temperature alloy slag. Background Technology
[0002] After processing in a submerged arc furnace, the smelted alloy slag and ferroalloy flow separately into their respective treatment pools via chutes (the treatment pool into which the alloy slag flows will be uniformly referred to as the slag bed below). The temperature of the alloy slag entering the slag bed is not lower than 1200℃, and it is expected that all of it can be discharged within 40 minutes; the slag discharge cycle for each furnace is approximately 3-4 hours; after a certain period of discharge, once a certain amount of slag has been reached (the slag amount can be controlled to be approximately 30t or 60t), to prevent the alloy slag from accumulating too thickly, a crushing and rolling mill can be started to prioritize the crushing and rolling of the alloy slag that has already flowed into the slag bed; during the crushing and rolling process, a small amount of water can be sprayed onto the processed alloy slag through the onboard spraying mechanism to cool it down; after a certain period of processing, the slag temperature is controlled. When the temperature drops to 700-800℃, the crushing truck can reverse the slag pushing process, pushing the pre-processed 30t or 60t slag into the crushing bed port. The slag is then transported to the designated area by a loader or slag truck. However, the crushing rollers connected to the crushing truck usually lack corresponding cooling mechanisms and require external cooling equipment. Otherwise, the crushing rollers are prone to deformation and damage due to high temperatures, which will also reduce the continuous working time of the crushing rollers. Some crushing rollers with built-in cooling structures can only cool the roller body and cannot effectively cool the crushing blocks on the surface of the roller. Therefore, the continuous working time of such crushing rollers is still limited. Otherwise, the crushing blocks on the surface of the roller are prone to deformation and damage due to continuous high temperatures. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] Reference Figures 1 to 5 As shown, this utility model provides a water-cooled rolling mill roller for high-temperature alloy slag treatment, comprising: a roller body 1, an mounting plate 2 fixedly connected to the surface of the roller body 1 through a mounting groove, and rolling blocks 3 symmetrically connected to the surface of the mounting plate 2, and fixing plates 4 symmetrically connected to both ends of the roller body 1, a fixing shaft 5 fixedly connected to the surface of the fixing plate 4, and a sealing plate 8 fixedly connected to the end of the fixing shaft 5 away from the fixing plate 4, while the fixing shaft 5 is movably connected to a diversion box 6 through a sealed bearing, and symmetrical drainage holes 7 are opened at the position of the fixing shaft 5 in the diversion box 6, and both the fixing shaft 5 and the fixing plate 4 are provided with liquid inlet grooves connecting to the main cooling groove opened inside the roller body 1, and a partition plate 10 is fixedly connected to the middle of the main cooling groove, the side of the main cooling groove is connected to the inner cavity of the mounting plate 2 through a liquid injection hole 9 and a liquid discharge hole, and the inner cavity of the mounting plate 2 is connected to the inner cavity of the rolling block 3 through a liquid injection port and a liquid discharge port, and a secondary partition plate 12 is fixedly connected inside the rolling block 3.
[0020] In this embodiment, when the crushing vehicle performs crushing and damage treatment on the high-temperature alloy slag using the crushing roller, the liquid inlet pipe injects coolant into the distribution box 6 at one end of the crushing roller through the connecting pipe. The coolant in the distribution box 6 flows through the drainage hole 7, sequentially through the liquid inlet groove opened by the fixed shaft 5 and the fixed plate 4, into the main cooling groove opened inside the roller body 1. The coolant also flows through the injection hole 9 opened on the side of the main cooling groove into the confluence groove on one side of the inner cavity of the corresponding mounting plate 2. The coolant in the confluence groove flows into the inner cavity of the corresponding connected crushing block 3 through the injection port, and the coolant flows out from the inner cavity of the crushing block 3. The coolant flows into the manifold on the other side of the inner cavity of the mounting plate 2 through the drain port, and then flows out from the drain hole at the bottom of the manifold. The coolant flows through the main cooling tank, the delivery tank and the drainage hole 7 in sequence before flowing into the distribution box 6 at the other end of the rolling roller. The coolant in the distribution box 6 can flow out through the connecting pipe, so that the rolling roller has its own water-cooling structure, which can enhance the water-cooling effect of the roller body 1 and the rolling block 3, reduce the probability of the rolling roller being accidentally deformed and damaged due to continuous high temperature, extend the continuous working time of the rolling roller, and the coolant that absorbs heat can also help to achieve the effect of waste heat recovery.
[0021] In a preferred embodiment, the roller body 1 has a cylindrical structure, and the partition plate 10 fixedly connected inside the roller body 1 has a circular structure. The main cooling groove inside the roller body 1 is divided into two groups of confluence grooves by the partition plate 10. At the same time, multiple groups of liquid injection holes 9 are opened at equal intervals around the circumference in one group of confluence grooves, and multiple groups of liquid drainage holes are opened at equal intervals around the circumference in the other group of confluence grooves.
[0022] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The partition plate 10 separates the two ends of the main cooling tank inside the roller body 1, ensuring that the coolant can flow in from one end of the main cooling tank and out from the other end, so that the coolant can flow smoothly through the inside of the roller body 1 and enhance the water cooling effect of the roller body 1.
[0023] In a preferred embodiment, multiple sets of mounting grooves are opened at equal intervals around the outer arc surface of the roller body 1. The mounting grooves are elongated and the mounting plate 2 fixedly connected inside the mounting grooves are also elongated. The upper surface of the mounting plate 2 is arc-shaped. At the same time, the inner cavity of the mounting plate 2 is connected to the corresponding injection hole 9 and drainage hole. The injection hole 9 and drainage hole are centrally symmetrically distributed at the bottom of the inner cavity of the mounting plate 2.
[0024] In this embodiment, as Figure 3 , Figure 4 and Figure 5The dimensions of the mounting groove and the mounting plate 2 are matched, which helps to enhance the sealing and fixing effect at the connection between the two. At the same time, the upper surface of the mounting plate 2 and the outer side of the roller body 1 are combined to form a complete circle. Furthermore, the two ends of the mounting plate 2 can be smoothly connected to the two ends of the main cooling tank through the cooperation of the injection hole 9 and the drainage hole, ensuring the fluidity of the coolant.
[0025] In a preferred embodiment, the main partition plate 11 is fixedly connected to the middle of the inner cavity of the mounting plate 2. The main partition plate 11 has a long strip structure, and the cross section formed by the combination of the mounting plate 2 and the main partition plate 11 has a H-shaped structure. The injection hole 9 and the drainage hole are located in different cavities inside the mounting plate 2.
[0026] In this embodiment, as Figure 3 , Figure 4 and Figure 5 The main partition plate 11 prevents the coolant flowing into the injection hole 9 from flowing directly out of the drain hole, thereby helping to restrict the flow path of the coolant and ensuring that the coolant can flow smoothly into the rolling block 3 connected to the mounting plate 2, thereby enhancing the water cooling effect of the rolling block 3.
[0027] In a preferred embodiment, multiple sets of positioning blocks 13 are fixedly connected at equal intervals along the length direction on the upper surface of the mounting plate 2. The positioning blocks 13 are rectangular in structure, and the rolling blocks 3 are fixedly connected to the upper surface of the mounting plate 2 relative to the positioning blocks 13. The liquid injection port and liquid drainage port opened on the upper surface of the mounting plate 2 are located on both sides of the main partition plate 11, and the liquid injection port and liquid drainage port correspond one-to-one with the position of the positioning blocks 13.
[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5 The positioning block 13 helps to enhance the positioning efficiency of the rolling block 3 when it is fixedly connected to the surface of the mounting plate 2. It also ensures that both ends of the inner cavity of each set of rolling blocks 3 can be smoothly connected to the corresponding liquid injection port and liquid discharge port, so that the coolant can flow smoothly inside the rolling block 3 and enhance the water cooling effect of the rolling block 3.
[0029] In a preferred embodiment, the compaction block 3 has a rectangular parallelepiped structure, with the upper end of the compaction block 3 having a frustum-shaped structure. The secondary partition plate 12, which is fixedly connected to the middle of the inner cavity of the compaction block 3, has a long strip-shaped structure. The secondary partition plate 12 and the corresponding main partition plate 11 are located in the same plane. At the same time, the inner cavity of the compaction block 3 forms a U-shaped structure through the secondary partition plate 12. The two ends of the inner cavity of the compaction block 3 are respectively connected to the injection port and the drainage port.
[0030] In this embodiment, as Figure 3 , Figure 4 and Figure 5The secondary partition plate 12 provides an inlet and outlet for coolant in the inner cavity of the rolling block 3, thereby effectively restricting the flow path of the coolant and ensuring the water-cooling effect of the coolant on the rolling block 3, so that the coolant can flow smoothly inside the rolling roller for cooling.
[0031] In a preferred embodiment, the fixed shaft 5 has a cylindrical structure, the sealing plate 8 fixedly connected to the end face of the fixed shaft 5 has a circular structure, and the diversion box 6 movably connected to the surface of the fixed shaft 5 has an annular structure. The axial section of the diversion box 6 has a U-shaped structure. At the same time, the connecting pipe is fixedly connected to the outer side of the diversion box 6, and multiple sets of drainage holes 7 are opened at equal intervals around the fixed shaft 5 in the circumferential direction at the position of the fixed shaft 5 in the inner cavity of the diversion box 6.
[0032] In this embodiment, as Figure 1 and Figure 2 The sealing plate 8 prevents coolant from flowing directly out of the opening on the end face of the fixed shaft 5. The distribution box 6 allows the connecting pipe and the rolling roller to rotate relative to each other, preventing accidental entanglement between the coolant delivery pipe and the rolling roller. The opening of the drainage hole 7 allows the coolant to flow smoothly between the distribution box 6 and the delivery groove on the fixed shaft 5, improving the flow effect of the coolant.
[0033] The water-cooled roller for treating high-temperature alloy slag of this invention, through the cooperation of a fixed shaft 5, a diversion box 6, a partition plate 10, a mounting plate 2, a main partition plate 11, a secondary partition plate 12, an injection hole 9, and a drainage hole, enables the roller to have a built-in water-cooling structure. This structure can simultaneously cool the roller body 1 and the rolling blocks 3 on the roller surface, thereby reducing the probability of accidental damage to the roller and helping to extend the continuous working time of the roller in high-temperature alloy slag.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
