Description

Technical Field

[0001] This utility model relates to the field of carbon black granulation technology, and in particular to a steam recovery heating device for carbon black granulation. Background Technology

[0002] Wet carbon black granulation technology is a process that mixes carbon black powder with water and forms granules through stirring. It is widely used in industries such as rubber, plastics, and coatings. With increasingly stringent environmental protection requirements, the advantages of this technology are becoming more and more significant. Wet granulation can not only improve the flowability and dispersibility of carbon black, but also reduce dust generation and improve the working environment. With continuous technological advancements, wet carbon black granulation equipment is gradually developing towards high efficiency and intelligence. New equipment adopts advanced control systems that can monitor and adjust the stirring and drying processes in real time to ensure the uniformity and quality stability of the granules.

[0003] Existing equipment still faces some significant drawbacks in use. During the granulation process, although adding water and stirring the carbon black powder can effectively improve the adhesion of the mixture, it also causes a large amount of carbon black to adhere to the inside of the equipment. This phenomenon not only increases the operating resistance of the equipment, but may also lead to uneven mixing, affecting the quality of the final product. The carbon black powder adhering to the equipment cannot be fully utilized, resulting in resource waste, increased production costs, and failure to meet actual needs. Utility Model Content

[0004] This utility model discloses a steam recovery heating device for carbon black granulation, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a preferred embodiment, the device includes a housing, one end of which is fixedly connected to a motor. One end of the motor's output shaft is fixedly connected to a stirring roller. The outer surface of the stirring roller is provided with threads for conveying and teeth for stirring and granulation. A steam mechanism is installed at the top of the housing for generating and conveying steam. A recovery mechanism is installed at the other end of the housing for recovering and heating steam. An activation mechanism is installed at the bottom of the steam mechanism for intermittently spraying steam to clean carbon black from the inner wall of the housing. The activation mechanism includes a first connecting hole, an activation block, a pressure tank, a piston, and a spring. A guide rod and a second connecting hole are provided. Steam compresses the piston and the excitation block, causing the first and second connecting holes to be staggered. The piston and the excitation block slide and compress the spring inside the pressure tank until the pressure inside the pressure tank is high enough to make the guide rod contact the inner wall of the pressure tank. The excitation block and the piston separate, making the first and second connecting holes connected. A jet hole is provided at the connection between the pressure tank and the outer shell. Steam is ejected from the jet hole, causing carbon black to fall off the inner wall of the outer shell. Multiple water pipes are provided at the top of the outer shell near the steam mechanism. A feed port is provided on the upper surface of one end of the outer shell, and a discharge port is provided at the bottom of the other end of the outer shell.

[0007] The outer shell and the pressure tank are fixedly connected, the piston is slidably connected to the pressure tank, the piston is slidably connected to the excitation block, the guide rod is fixedly connected to the top of the excitation block, and the guide rod is slidably connected to the piston.

[0008] The bottom of the excitation block is provided with an arc-shaped groove, which increases the contact area between the excitation block and the steam, so that the excitation block is subjected to uniform pressure.

[0009] In a preferred embodiment, the steam mechanism includes a mounting shell fixedly connected to the top of the outer casing. A heat preservation barrel and a fixing cylinder are fixedly connected to the top of the mounting shell. A heating tank is fixedly connected inside the heat preservation barrel. A water inlet pipe is inserted into one side of the heating tank. A connecting pipe is inserted into the top of the heating tank. Multiple heating plates are provided at the bottom of the heating tank.

[0010] The fixed cylinder is equipped with a temporary storage tank and a storage tank inside. One end of the connecting pipe is connected to the temporary storage tank, and the temporary storage tank and the storage tank are connected to each other. The top of the fixed cylinder is equipped with a diversion pipe, which is connected to the storage tank and to multiple pressure tanks.

[0011] The recycling mechanism includes a recycling tube inserted into the other end of the outer shell, a filter cover fixedly connected to the inner wall of the other end of the outer shell near the recycling tube, and the other end of the recycling tube communicating with a temporary storage tank.

[0012] The outer wall of the recovery tube is provided with a protective cylinder, and the inside of the protective cylinder is provided with multiple heating plates.

[0013] As can be seen from the above, the steam recovery heating device for carbon black granulation provided by this utility model has the following technical effects.

[0014] Firstly, the internal steam pressure of the pressure tank gradually increases, and the steam squeezes the surface of the excitation block and piston, causing the piston and excitation block to compress the spring. The steam pressure causes the excitation block and piston to slide against each other until they are pressed together, causing the first and second connecting holes to be misaligned. This continues until the piston and excitation block slide upwards, causing the guide rod to contact the top inner wall of the pressure tank, preventing the excitation block from sliding further. The piston continues to slide and compress the spring, connecting the first and second connecting holes. The steam pressure at the bottom of the piston is released from the inner wall surface of the outer shell through the first connecting hole, the second connecting hole, and the jet hole. A large amount of steam peels off the carbon black adhering to the inner wall of the outer shell, thus reducing the adhesion of carbon black in the wet granulation equipment.

[0015] Secondly, the steam enters the interior of the shell and adheres to the surface of the carbon black. After the carbon black is stirred and granulated, the steam wets the surface of the carbon black particles, which reduces the cracking of the carbon black particles and the surface carbon black dust. Excess steam enters the interior of the recovery pipe through the filter cover. Inside the heating plate, multiple heating plates heat the steam inside the recovery pipe. The heated steam is then injected into the interior of the temporary storage tank for recycling. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Reference Figure 1 — Figure 5 The system includes a housing 1, with a motor 2 fixedly connected to one end of the housing 1. A stirring roller 10 is fixedly connected to one end of the output shaft of the motor 2. The outer surface of the stirring roller 10 is provided with threads for conveying and stirring teeth for stirring and granulation. A steam mechanism is installed on the top of the housing 1 for generating and conveying steam. A recovery mechanism is installed at the other end of the housing 1 for recovering and heating steam. An excitation mechanism is installed at the bottom of the steam mechanism for intermittently spraying steam to clean carbon black from the inner wall of the housing 1. The excitation mechanism includes a first connecting hole 19, an excitation block 20, a pressure tank 21, a piston 22, a spring 23, a guide rod 24, and a second connecting hole 25. The piston 22 and the excitation block 20 are pressed together, causing the first connecting hole 19 and the second connecting hole 25 to be staggered. The piston 22 and the excitation block 20 slide and compress the spring 23 inside the pressure tank 21 until the pressure inside the pressure tank 21 is large enough to make the guide rod 24 contact the inner wall of the pressure tank 21. The excitation block 20 and the piston 22 separate from each other, so that the first connecting hole 19 and the second connecting hole 25 are connected. A jet hole is provided at the connection between the pressure tank 21 and the outer shell 1. Steam is ejected from the jet hole, causing carbon black to fall off the inner wall of the outer shell 1. Multiple water pipes are provided at the top of the outer shell 1 near the steam mechanism. A feed port 3 is provided on the upper surface of one end of the outer shell 1, and a discharge port 9 is provided at the bottom of the other end of the outer shell 1.

[0025] The outer shell 1 and the pressure tank 21 are fixedly connected, the piston 22 is slidably connected to the pressure tank 21, the piston 22 is slidably connected to the excitation block 20, the guide rod 24 is fixedly connected to the top of the excitation block 20, and the guide rod 24 is slidably connected to the piston 22.

[0026] The bottom of the excitation block 20 is provided with an arc-shaped groove, which increases the contact area between the excitation block 20 and the steam, so that the excitation block 20 is subjected to uniform pressure.

[0027] In this embodiment, steam enters the interior of pressure tank 21 through diversion pipe 18. The steam pressure inside pressure tank 21 gradually increases, and the steam squeezes the surfaces of excitation block 20 and piston 22, causing piston 22 and excitation block 20 to compress spring 23. Since there is a sliding connection between excitation block 20 and piston 22, the steam pressure will cause excitation block 20 and piston 22 to slide against each other until excitation block 20 and piston 22 are pressed together, causing the first connecting hole 19 and the second connecting hole 25 to be misaligned. When the pressure at the bottom of pressure tank 21 and piston 22 increases to compress spring 23, piston 22 and excitation block 20 slide upward.

[0028] Furthermore, the guide rod 24 is brought into contact with the top inner wall of the pressure tank 21, preventing the excitation block 20 from sliding further. The piston 22 continues to slide and compress the spring 23, connecting the first connecting hole 19 and the second connecting hole 25. The steam pressure at the bottom of the piston 22 is released from the inner wall surface of the outer shell 1 through the first connecting hole 19, the second connecting hole 25, and the jet hole. A large amount of steam peels off the carbon black adhering to the inner wall of the outer shell 1, thereby reducing the adhesion of carbon black in the wet granulation equipment.

[0029] Reference Figure 1 , Figure 2 , Figure 3 In a preferred embodiment, the steam mechanism includes a mounting shell 4 fixedly connected to the top of the outer shell 1. A heat preservation tank 5 and a fixing cylinder 6 are fixedly connected to the top of the mounting shell 4 respectively. A heating tank 14 is fixedly connected inside the heat preservation tank 5. A water inlet pipe 13 is inserted into one side of the heating tank 14. A connecting pipe 15 is inserted into the top of the heating tank 14. Multiple heating plates are provided at the bottom of the heating tank 14.

[0030] The fixed cylinder 6 is equipped with a temporary storage tank 16 and a storage tank 17. One end of the connecting pipe 15 is connected to the temporary storage tank 16, and the temporary storage tank 16 and the storage tank 17 are connected. The top of the fixed cylinder 6 is equipped with a diversion pipe 18, which is connected to the storage tank 17 and to multiple pressure tanks 21.

[0031] The recycling mechanism includes a recycling tube 8 inserted into the other end of the outer casing 1. A filter cover 12 is fixedly connected to the inner wall of the other end of the outer casing 1 near the recycling tube 8. The other end of the recycling tube 8 is connected to a temporary storage tank 16.

[0032] A protective cylinder 7 is installed on the outer wall of the recovery pipe 8, and multiple heating plates 11 are installed inside the protective cylinder 7.

[0033] In this embodiment, when steam enters the interior of the outer shell 1, it adheres to the surface of the carbon black. After the carbon black is stirred and granulated, the steam wets the surface of the carbon black particles, which reduces the cracking of the carbon black particles and the surface carbon black dust. Excess steam enters the interior of the recovery pipe 8 through the filter cover 12. Inside the heating plate 11, multiple heating plates 11 heat the steam inside the recovery pipe 8. The heated steam is then injected into the interior of the temporary storage tank 16 for recycling.

[0034] Working principle: During use, carbon black powder is fed into the interior of the outer shell 1 through the feed inlet 3. The motor 2 is started, driving the stirring roller 10 to rotate and convey the carbon black powder forward. Water is sprayed into the interior of the outer shell 1 through the water pipe, causing the stirring roller 10 to continuously rotate and evenly mix the carbon black powder and water. After the carbon black and water are mixed, the carbon black adhesion increases. The water pipe is located at the bottom of the mounting shell 4 near the steam mechanism. A large amount of carbon black adheres to the inner wall of the outer shell 1 near the bottom of the mounting shell 4. Water is injected into the heating tank 14 through the water inlet pipe 13. Multiple heating plates at the bottom of the heating tank 14 heat the interior of the heating tank 14. Water generates steam, which enters the interior of temporary storage tank 16 through connecting pipe 15. The steam is temporarily stored inside temporary storage tank 16. If recovery pipe 8 does not inject steam into temporary storage tank 16, the steam inside temporary storage tank 16 is discharged into storage tank 17. Steam is then injected into distribution pipe 18 through storage tank 17. The steam enters the interior of pressure tank 21 through distribution pipe 18, and the steam pressure inside pressure tank 21 gradually increases. The steam compresses the surfaces of ignition block 20 and piston 22, causing piston 22 and ignition block 20 to compress spring 23. Due to the sliding connection between ignition block 20 and piston 22, the steam... Steam pressure causes the actuating block 20 and piston 22 to slide against each other until they are pressed together, thus misaligning the first connecting hole 19 and the second connecting hole 25. As the pressure at the bottom of the pressure tank 21 and piston 22 increases, it compresses the spring 23 until piston 22 and actuating block 20 slide upwards, causing guide rod 24 to contact the top inner wall of pressure tank 21, preventing actuating block 20 from sliding further. Piston 22 continues to slide, compressing spring 23 and connecting the first connecting hole 19 and the second connecting hole 25. This allows the steam pressure at the bottom of piston 22 to pass through the first connecting hole 19, the second connecting hole 25, and the jet port. The steam released from the inner wall surface of the outer shell 1 will peel off the carbon black adhering to the inner wall of the outer shell 1, thereby reducing the carbon black adhesion in the wet granulation equipment. When the steam enters the interior of the outer shell 1, it will adhere to the carbon black surface. After the carbon black is stirred and granulated, the steam will wet the surface of the carbon black particles, thereby reducing the cracking of the carbon black particles and the surface carbon black dust. The excess steam enters the interior of the recovery pipe 8 through the filter cover 12. Inside the heating plate 11, multiple heating plates 11 heat the steam inside the recovery pipe 8. The heated steam is then injected into the interior of the temporary storage tank 16 for recycling.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
