Description

Technical Field

[0001] This utility model relates to the technical field of cold slag equipment, and in particular, to a cold quenching drum device and a molten slag cooling device. Background Technology

[0002] In industrial production processes such as metallurgy and chemical engineering, large amounts of high-temperature molten slag are generated, with temperatures typically reaching 1500℃ to 1600℃. Improper handling of this high-temperature slag not only leads to severe energy waste but also has adverse environmental impacts.

[0003] From an energy perspective, high-temperature molten slag contains enormous thermal energy. According to statistics, every ton of high-temperature molten slag produced carries the equivalent heat of 50 to 100 kilograms of standard coal. Given the current global energy shortage, recovering and utilizing this thermal energy is of significant practical importance, effectively improving energy efficiency and reducing energy costs for businesses. Furthermore, from an environmental protection perspective, direct discharge of high-temperature molten slag will cause soil cracking and vegetation withering due to the intense heat. Simultaneously, the slag may release harmful gases and dust during cooling, polluting the air. In addition, untreated slag accumulation occupies significant amounts of land resources, resulting in land waste.

[0004] Currently, the commonly used industrial methods for treating high-temperature slag mainly include water quenching, air cooling, and drum cooling.

[0005] Water quenching: This method involves contacting high-temperature molten slag with high-pressure water, utilizing the rapid evaporation of the water to remove a large amount of heat, thus achieving rapid cooling of the slag. This method has high cooling efficiency, but it generates a large amount of water vapor and slag-containing wastewater, which can easily cause secondary pollution if not properly treated. Furthermore, the heat energy of the molten slag is difficult to recover effectively during the water quenching process.

[0006] Air cooling: This method uses air as the cooling medium, cooling the high-temperature molten slag through natural convection or forced ventilation. It is environmentally friendly, producing no wastewater, but the cooling rate is relatively slow, it requires a large area, and it has low efficiency in heat recovery.

[0007] Drum method: High-temperature molten slag is fed into a rotating drum, and the molten slag is cooled faster through heat exchange between the drum wall and the air, as well as the tumbling of the molten slag inside the drum.

[0008] Among them, the cooling speed of the drum method is improved to a certain extent compared with the air cooling method, but because the slag is difficult to be evenly distributed in the drum, the slag cannot be cooled evenly and quickly. Utility Model Content

[0009] The purpose of this invention is to provide a cold quenching drum device and a slag cooling equipment to solve the technical problem that the slag is difficult to distribute evenly in the drum, resulting in the slag not being able to cool evenly and quickly.

The output channel is connected to the input cavity through the plurality of split output holes.

[0018] In an embodiment of this utility model, the rotary drive mechanism further includes an outer rotary drive structure and an outer shaft. The outer rotary drive structure is connected to the outer cylinder through the outer shaft and can drive the outer shaft to rotate, thereby causing the outer shaft to rotate. The inner shaft passes through the outer shaft and is arranged to rotate relative to the outer shaft.

[0019] This utility model also provides a slag cooling device, including the above-mentioned quenching drum device.

[0020] In an embodiment of this utility model, the slag cooling equipment further includes a drum lifting device. The drum lifting device includes a device support and a drum lifting mechanism. The drum lifting mechanism is mounted on the device support and is used to install the quenching drum device and drive the quenching drum device to move along the height direction. The device support has a space below the quenching drum device for placing a slag basin, which is used to hold high-temperature molten slag. The drum lifting mechanism can drive the quenching drum device to move downwards until the cooling drum of the quenching drum device extends into the high-temperature molten slag, so that the cooling drum cools the high-temperature molten slag in the slag basin.

[0021] In an embodiment of this utility model, the drum lifting device further includes a control mechanism and a liquid level monitoring structure.

[0054] 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.

[0055] Implementation Method 1

[0056] like Figure 1 and Figure 3 As shown, this utility model provides a cold quenching drum device, including: a cooling drum 1, having an inner cylinder 11 and an outer cylinder 12, the inner cylinder 11 being located inside the outer cylinder 12, and an annular cavity 13 being formed between the inner sidewall of the inner cylinder 11 and the outer cylinder 12; wherein, the outer sidewall of the inner cylinder 11 is provided with helical protrusions 14, and a crushing channel is formed between the helical protrusions 14 and the inner sidewall of the outer cylinder 12; a rotary drive mechanism 2, connected to the cooling drum 1 and capable of driving the inner cylinder 11 to rotate relative to the outer cylinder 12; an input structure 3, located at one end of the cooling drum 1 and communicating with the annular cavity 13; and an output structure 4, located at the other end of the cooling drum 1 and communicating with the annular cavity 13.

[0057] In some embodiments of this invention, the annular cavity 13 between the outer wall of the inner cylinder 11 and the inner wall of the outer cylinder 12 is used as a cooling medium flow cavity, allowing the cooling medium to exchange heat with the high-temperature molten slag outside the outer cylinder 12 to cool the molten slag. This also allows the high-temperature molten slag to form a uniform thin layer between the outer wall of the inner cylinder 11 and the inner wall of the outer cylinder 12, thereby improving cooling efficiency and effect. Furthermore, by providing helical protrusions 14 on the outer wall of the inner cylinder 11 and forming a crushing channel with the inner wall of the outer cylinder 12, and by driving the inner cylinder 11 to rotate relative to the outer cylinder 12, the helical protrusions 14 push the cooling medium forward to the output structure 4. During this pushing process, the cooling medium flowing into the crushing channel is cut and crushed by the helical protrusions 14 under the differential speed action of the inner cylinder 11 and the outer cylinder 12, and then thrown towards the inner wall of the outer cylinder 12 under centrifugal force, thereby further improving the efficiency of heat exchange between the molten slag and the cooling medium. The cooling medium can be, but is not limited to, air, water, or heat transfer oil.

[0058] Furthermore, in some embodiments of this invention, the annular cavity 13 between the outer wall of the inner cylinder 11 and the inner wall of the outer cylinder 12 can be used as a cooling chamber for the high-temperature molten slag. This allows the high-temperature molten slag to exchange heat with both the inner cylinder 11 and the outer cylinder 12 simultaneously. By controlling the width of the annular cavity 13, a thin slag layer of uniform thickness can be formed between the outer wall of the inner cylinder 11 and the inner wall of the outer cylinder 12, thereby improving the cooling efficiency of the molten slag. Further, by providing helical protrusions 14 on the outer wall of the inner cylinder 11 and cooperating with the outer cylinder 12, The inner wall of cylinder 2 forms a crushing channel, thereby using the spiral protrusions 14 to push the high-temperature molten slag forward to the output structure 4. During the pushing process, the molten slag flows into the crushing channel and is cut and crushed by the spiral protrusions 14 under the differential speed action of the inner cylinder 11 and the outer cylinder 12. The molten slag is broken into droplets, and the molten slag droplets are thrown towards the inner wall of the outer cylinder 12 under the action of centrifugal force. This further improves the cooling speed of the molten slag after heat exchange with the inner cylinder 11 and the outer cylinder 12, and also allows the molten slag to cool and solidify into granules, ensuring smooth discharge of the molten slag after cooling. In order to further improve the cooling efficiency and realize the heat recovery of the high-temperature molten slag, a cooling medium flow structure is provided in the inner cylinder 11 and / or the outer wall of the outer cylinder 12, so that the heat absorbed by the inner cylinder 11 and / or the outer cylinder 12 in heat exchange with the high-temperature molten slag can be absorbed by the cooling medium. The cooling medium can be, but is not limited to, air, water or heat transfer oil.

[0059] In this embodiment of the invention, the cooling effect can be adjusted by adjusting the width of the annular cavity 13 (i.e., the distance between the outer wall of the inner cylinder 11 and the inner wall of the outer cylinder 12), the width of the crushing channel (i.e., the distance between the helical teeth 14 and the inner wall of the outer cylinder 12), and / or the pitch of the helical teeth 14, i.e., the width of the helical channel 141 of the helical teeth 14. The width of the annular cavity 13 is the sum of the width of the crushing channel and the height of the helical teeth protruding relative to the outer wall of the inner cylinder. In this embodiment, the width of the crushing channel is preferably less than the height of the helical teeth protruding relative to the outer wall of the inner cylinder. The height of the helical teeth 14 protruding relative to the outer wall of the inner cylinder 11 is preferably 3mm to 10mm.

[0060] Combination Figure 1 , Figure 2 and Figure 4As shown in the embodiment of this utility model, the rotary drive mechanism 2 includes an inner rotary drive structure 22 and an inner shaft 21. The inner shaft 21 passes through the outer cylinder 12 and is connected to the inner cylinder 11. The inner rotary drive structure 22 is connected to the inner shaft 21 and can drive the inner shaft 21 to rotate. In addition, the rotary drive mechanism 2 also includes an outer rotary drive structure 24 and an outer shaft 23. The outer rotary drive structure 24 is connected to the outer cylinder 12 through the outer shaft 23 and can drive the outer shaft 23 to drive the outer cylinder 12 to rotate. The inner shaft 21 passes through the outer shaft 23 and is arranged to rotate relative to the outer shaft 23. By setting up an inner rotary drive structure 22 and an outer rotary drive structure 24 to control the rotational speeds of the inner cylinder 11 and the outer cylinder 12 respectively, the rotation of the outer cylinder 12 can be improved to enhance the heat exchange between the internal cooling medium and the external high-temperature molten slag. Furthermore, the rotational speeds of the inner cylinder 11 and the outer cylinder 12 can be different to create a differential effect. The differential effect between the inner and outer cylinders 11 can be increased by controlling the rotation direction of the outer cylinder 12 to be opposite to that of the inner cylinder 11, thereby further improving the uniformity of the cooling medium distribution within the annular cavity 13 and the shearing and crushing effect of the helical teeth 14. Specifically, the two ends of the inner shaft 21 are connected to the two inner rotary drive structures 22 via couplings. The specific structure and working principle of the inner rotary drive structure 22 are the same as in the prior art and will not be detailed here. The two ends of the outer shaft 23 are connected to the two outer rotary drive structures 24 via couplings. The specific structure and working principle of the outer rotary drive structure 24 are the same as in the prior art and will not be detailed here.

[0061] like Figure 1 As shown, in this embodiment of the present invention, the input structure 3 includes an input channel 31 disposed within the inner shaft 21, and the output structure 4 includes an output channel 41 disposed within the inner shaft 21. By providing the input channel 31 and the output channel 41 within the inner shaft 21, the structure is simplified. Specifically, an input cavity 15 is formed between the inner sealing plate at one end of the inner cylinder 11 and the outer sealing plate at one end of the outer cylinder 12; an output cavity 16 is formed between the inner sealing plate at the other end of the inner cylinder 11 and the outer sealing plate at the other end of the outer cylinder 12; the annular cavity 13 is connected to the input channel 31 through the input cavity 15, and the annular cavity 13 is connected to the output channel 41 through the output cavity 16.

[0062] In addition, such as Figure 1 As shown, the cooling drum 1 also includes multiple air vents 5. The air vents 5 are provided with air vents. The multiple air vents 5 are installed at both ends of the outer cylinder 12 and are connected to the inner cavity of the inner cylinder 11. When the internal air pressure of the inner cylinder 11 increases, it can be discharged outward through the air vents.

[0063] To ensure that the molten slag is evenly distributed within the input cavity 15, and thus more evenly distributed within the annular cavity 13, such as... Figure 1As shown in the embodiment of this utility model, the input structure 3 further includes multiple diversion input holes 32. These multiple diversion input holes 32 are spaced apart circumferentially along the inner shaft 21, and the input channel 31 is connected to the input cavity 15 through these multiple diversion input holes 32. Furthermore, multiple guide plates are arranged at intervals around the input channel 31 on the outer end face of the inner cylinder 11 located within the input cavity 15 or on the inner end face of the outer cylinder 12 located within the input cavity 15. These guide plates form multiple guide channels corresponding to the multiple diversion input holes 32, thereby cooperating with centrifugal force to guide the cooling medium to flow evenly into the annular cavity 13. Specifically, the number of diversion input holes 32 can be set to twelve as in this embodiment, or it can be set to other numbers as needed.

[0064] like Figure 1 As shown, to ensure the cooling medium after heating is smoothly output from the output cavity 16 to the output channel 41, in this embodiment of the invention, the output structure 4 further includes multiple diversion output holes 42. These multiple diversion output holes 42 are spaced apart circumferentially along the inner shaft 21, and the output channel 41 is connected to the input cavity 15 through these multiple diversion output holes 42. Specifically, the number of diversion output holes 42 can be set to twelve as in this embodiment, or it can be set to other numbers as needed.

[0065] Implementation Method 2

[0066] This utility model also provides a slag cooling device, including a quenching roller device. The quenching roller device in this embodiment has the same specific structure, working principle and beneficial effects as the quenching roller device in embodiment one, and will not be described again here.

[0067] like Figure 5 and Figure 7 As shown in the embodiment of this utility model, the slag cooling equipment further includes a drum lifting device. The drum lifting device includes a device support 6 and a drum lifting mechanism 8. The drum lifting mechanism 8 is installed on the device support 6 and is used to install the quenching drum device and drive the quenching drum device to move along the height direction. The device support 6 has a space below the quenching drum device for placing a slag basin 7, which is used to hold high-temperature molten slag. The drum lifting mechanism 8 can drive the quenching drum device to move downwards until the cooling drum 1 of the quenching drum device extends into the high-temperature molten slag, so that the cooling drum 1 cools the high-temperature molten slag in the slag basin 7.

[0068] The cooling drum 1 of the quenching drum device is directly inserted into the high-temperature molten slag in the slag basin 7 by the downward movement of the drum lifting mechanism 8. The cooling drum 1 directly cools the high-temperature molten slag in the slag basin 7. During the cooling process, the drum lifting mechanism 8 adapts to the change in the liquid level of the high-temperature molten slag in the slag basin 7, so that the cooling drum 1 of the quenching drum device can always be located at a preset position below the liquid surface of the high-temperature molten slag, so as to ensure the continuity of the cooling process and the cooling effect.

[0069] During the cooling process of the cooling drum 1 cooling the high-temperature molten slag in the slag basin 7, the temperature of the high-temperature molten slag changes, and the feeding and / or discharging of the high-temperature molten slag causes changes in the liquid level of the high-temperature molten slag in the slag basin 7. This, in turn, causes changes in the immersion depth of the cooling drum 1. The immersion depth of the cooling drum 1 changes the contact area between the cooling drum 1 and the high-temperature molten slag, thus affecting the cooling effect. Therefore, the cooling drum 1 is positioned below the liquid surface of the high-temperature molten slag by moving the cooling drum device driven by the drum lifting mechanism 8. This prevents the cooling drum 1 from being immersed too deeply in the high-temperature molten slag, which would affect the cooling effect, and also prevents the cooling drum 1 from being immersed too shallowly in the high-temperature molten slag, which would affect the cooling efficiency.

[0070] like Figure 5 and Figure 7 As shown, in order to enable the cooling medium input structure 3 of the cold quenching drum device driven by the drum lifting mechanism 8 to automatically descend to a preset position below the liquid surface of the high-temperature molten slag before the cooling treatment, and to adaptively move with the change of the liquid surface of the high-temperature molten slag during the cooling treatment, in the embodiment of this utility model, the drum lifting device also includes a control mechanism 120 and a liquid level monitoring structure. The liquid level monitoring structure is used to monitor the liquid level information of the molten slag in the slag basin 7. The control mechanism 120 is electrically connected to the drum lifting mechanism 8 and the liquid level monitoring structure respectively, and can control the drum lifting mechanism 8 to drive the cold quenching drum device to move along the height direction according to the liquid level information fed back by the liquid level monitoring structure.

[0071] like Figure 5 and Figure 7As shown in the embodiment of this utility model, the drum lifting device also includes a temperature monitoring structure. The temperature monitoring structure is used to monitor the temperature information of the molten slag in the slag basin 7. The control mechanism 120 is also electrically connected to the rotation drive mechanism 2 of the quenching drum device and the temperature monitoring structure, respectively. It can control the drum lifting mechanism 8 to move the quenching drum device along the height direction and / or adjust the rotation speed of the cooling drum 1 driven by the rotation drive mechanism 2 according to the liquid level information fed back by the liquid level monitoring structure and the temperature information fed back by the temperature monitoring device. By setting the temperature monitoring structure to monitor the temperature information of the molten slag in the slag basin 7, on the one hand, the drum lifting mechanism 8 can be controlled to move the quenching drum device along the height direction according to the temperature of the high-temperature molten slag, thereby changing the immersion depth of the cooling drum 1. On the other hand, since the rotation speed of the cooling drum 1 will change the residence time of the cooling medium in the annular cavity 13, thus affecting the cooling effect, the drum lifting mechanism 8 can be controlled to move the quenching drum device along the height direction according to the temperature of the high-temperature molten slag, thereby changing the residence time of the cooling medium in the cooling drum 1, thereby ensuring the cooling effect and cooling efficiency.

[0072] like Figure 6 and Figure 8 As shown in the embodiment of this utility model, the slag cooling equipment further includes a cover 9, which covers the slag basin 7. The temperature probe of the temperature monitoring structure and the liquid level probe of the liquid level monitoring structure are located inside the cover 9. By covering the slag basin 7 with the cover 9 for protection, not only can the emission of harmful gases and dust from the slag be reduced, but the slag can also be kept warm, reducing heat loss and lowering safety risks.

[0073] Specifically, in combination Figure 6 , Figure 8 and Figure 9 As shown, the cover 9 has a bottom slot 91 facing downwards and a front slot 92 facing forwards. The front slot 92 is connected to the bottom slot 91. Above the front slot 92, the cover 9 has a baffle 94 extending forward, and below the baffle 94 is a space for accommodating the cooling drum 1. Thus, while the cooling drum 1 is processing the high-temperature molten slag, the cover 9 can still provide real-time protection for the molten slag in the slag basin 7. The shape of the bottom slot 91 can be designed according to the shape of the slag basin 7 to ensure that the edge of the bottom slot 91 of the cover 9 fits snugly against the surface of the slag basin 7, thereby improving the sealing performance of the cover 9. The cover 9 can be made of a high-temperature resistant and corrosion-resistant material. Furthermore, to improve the heat insulation effect of the cover 9, the inner wall surface of the cover 9 is provided with a heat insulation layer made of heat insulation material, which can be, but is not limited to, ceramic fiber. The track 101 is installed on the roof of the plant.

[0074] In addition, such as Figure 9As shown, the slag cooling equipment also includes a measuring arm 140 and a lifting and adjusting structure. One end of the measuring arm 140 is mounted on the cover 9 via the lifting and adjusting structure, and the other end of the measuring arm 140 extends into the cover 9. The liquid level measuring probe of the liquid level monitoring structure and the temperature measuring probe of the temperature monitoring structure are both mounted on the measuring arm 140. The lifting and adjusting structure may be, but is not limited to, an electric telescopic rod.

[0075] In this embodiment, both the liquid level measuring probe of the liquid level monitoring structure and the temperature measuring probe of the temperature monitoring structure are preferably non-contact measurement methods. For example, the liquid level measuring probe can be an ultrasonic liquid level measuring probe, and the temperature measuring probe can be an infrared temperature measuring probe. This can avoid contact with the molten slag and prevent easy damage. However, since the liquid level of the high-temperature molten slag will change, the measurement distance between the liquid level measuring probe and the temperature measuring probe and the liquid surface of the high-temperature molten slag will also change. The measurement distance between the liquid level measuring probe and the temperature measuring probe and the liquid surface of the high-temperature molten slag can be adjusted by moving the measuring arm 140 through the lifting and adjusting structure, thereby avoiding the measurement distance from affecting the accuracy of the measurement.

[0076] like Figure 8 and Figure 9 As shown, the slag cooling equipment also includes a display structure, which is electrically connected to the control mechanism 120. The control mechanism 120 can transmit liquid level information and temperature information to the display structure for display, so that operators can easily access the information. The temperature monitoring structure, liquid level monitoring structure, and display structure can be integrated into a slag data acquisition structure 150 and installed on the cover 9.

[0077] In addition, such as Figure 6 and Figure 8 As shown, the slag cooling equipment also includes a cover moving mechanism 10 and a slag basin moving mechanism 110. The slag basin 7 is installed on the slag basin moving mechanism 110, which can drive the slag basin 7 to move. The cover moving mechanism 10 includes at least one track 101 and at least one cover moving drive structure 102. The track 101 is located above the cover 9, and the cover 9 is suspended on the track 101 via the cover moving drive structure 102. The cover moving drive structure 102 can move along the track 101 and drive the cover 9 to move synchronously with the slag basin 7. By setting the slag basin moving mechanism 110 to drive the slag basin 7 to move and setting the cover moving mechanism 10 to drive the cover 9 to move synchronously with the slag basin 7, the transfer of molten slag is facilitated, and the cover 9 can also provide real-time protection during the transfer process.

[0079] Combination Figure 8 and Figure 9 As shown, one side of the cover 9 is also provided with a side slot 93. The side slot 93 is used for the slag chute 160 to extend into the cover 9, allowing the high-temperature molten slag to slide from the slag chute 160 into the slag basin 7. Thus, the cover 9 can provide real-time protection for the molten slag in the slag basin 7 during the process of the slag basin 7 receiving molten slag. Specifically, the side slot 93 is connected to the front slot 92. Before the slag basin 7 receives molten slag, the cover 9 is moved from the rear to the front of the slag basin 7 by the cover moving mechanism 10 and covers the slag basin 7. The slag discharge end of the slag chute 160 extends from the front slot 92 into the side slot 93 and into the cover 9. The shape of the side slot 93 is designed according to the shape of the slag discharge end of the slag chute 160 to ensure that the edge of the side slot 93 of the cover 9 can fit against the surface of the slag chute 160, thereby improving the sealing performance of the cover 9.
