Description

Technical Field

[0001] This utility model relates to the field of coal chemical equipment technology, specifically a coal tar dehydration device. Background Technology

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor produced during the dry distillation of coal. Coal tar can be classified into low-temperature coal tar, medium-temperature coal tar, and high-temperature coal tar according to the dry distillation temperature. The coal tar obtained in coke production belongs to high-temperature coal tar. It is one of the coke oven gas purification products condensed and separated during the cooling process of crude coal gas.

[0003] Current coal tar dewatering equipment typically uses a unidirectional rotation mode, which results in insufficient mixing of materials within the container, especially near the container wall where "dead zones" often appear, meaning the materials cannot be effectively stirred. In addition, insufficient stirring intensity or improper stirring methods may lead to material stratification, affecting the quality of the final product.

[0004] Patent CN222064429U discloses a coal tar precipitation and dehydration device, which includes a shell, support legs, inlet, outlet, exhaust port, heating layer, and filter structure. This invention achieves preliminary stirring by adding coal tar to the inlet and controlling a motor. The motor's output drives a second rotating shaft, which in turn rotates a ring sleeve. However, despite this design improvement, in practical use, the device relies solely on a single stirring plate, resulting in unsatisfactory mixing and uneven material mixing. Therefore, designing a more practical and effective coal tar dehydration device is essential. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-7 This utility model provides a technical solution: a coal tar dehydration device, including a reaction chamber 1, a central shaft 2 movably installed in the center of the reaction chamber 1, a servo motor 3 fixedly installed at the upper end of the reaction chamber 1 and the output end of the servo motor 3 fixedly connected to the central shaft 2, an edge protrusion 21 fixedly installed on the side wall of the central shaft 2, a lifting sleeve 4 provided outside the central shaft 2 and the edge protrusion 21, the lifting sleeve 4 being movably sleeved outside the central shaft 2 and the edge protrusion 21 by a reciprocating lifting component 5, a detachable stirring component 6 provided on the lifting sleeve 4, the detachable stirring component 6 being mirror-symmetrically arranged on the side wall of the lifting sleeve 4 and forming a stirring group, the stirring group being arranged in a linear array along the axial direction of the lifting sleeve 4, a feeding component 7 provided at the upper end of the reaction chamber 1 and a discharging component 8 provided at the lower end, an inspection port being opened through the side wall of the reaction chamber 1 and an inspection plate 9 being fixedly installed in the inspection port by bolts;

[0030] The reaction chamber 1 is the main container for the entire dehydration process. It contains a central shaft 2, driven by a servo motor 3, allowing the central shaft 2 to rotate. A lifting sleeve 4 is movably fitted around the central shaft 2 and the edge protrusion 21. The edge protrusion 21 is designed to rotate the lifting sleeve 4 along with the central shaft 2, and allows the lifting sleeve 4 to move up and down during rotation. Its up-and-down movement is controlled by a reciprocating lifting component 5, thereby achieving thorough stirring and mixing of the materials. By combining rotation and up-and-down movement, this device can create a three-dimensional stirring pattern within the reaction chamber. This stirring method is more efficient than traditional unidirectional stirring because it ensures that the liquid is stirred in the same direction throughout the entire process. Uniform mixing within the reaction chamber improves dehydration efficiency. Detachable stirring components 6 are installed symmetrically on both sides of the lifting sleeve 4, forming a stirring group. Multiple such stirring groups are arranged linearly along the axial direction, ensuring uniform distribution and efficient mixing of materials throughout the reaction chamber 1. Since the stirring components are detachable, cleaning and maintenance are easier, reducing downtime and improving the overall efficiency of the equipment. The feed component 7 and discharge component 8 are located at the top and bottom of the reaction chamber 1, respectively, for inputting the coal tar to be processed and outputting the processed product. The inspection plate 9 is fixed to the inspection port on the side wall of the reaction chamber 1 by bolts, facilitating equipment inspection and maintenance by maintenance personnel.

[0031] Specifically, the lifting sleeve 4 includes a top plate 41, a central cylinder 42, and a base 43. The top plate 41, the central cylinder 42, and the base 43 are fixedly connected from top to bottom. The reciprocating lifting component 5 includes a fixing block 51 and a guide rod 52. The fixing block 51 is fixedly installed at the edge of the top wall inside the reaction tank 1. The guide rod 52 is fixedly installed at one end of the fixing block 51 adjacent to the top plate 41. An annular lifting groove 411 is opened on the side wall of the top plate 41, and the guide rod 52 is movably installed in the annular lifting groove 411.

[0032] When the servo motor 3 drives the central shaft 2 to rotate, due to the presence of the edge protrusion 21, the central shaft 2 will drive the lifting sleeve 4 to rotate together. At the same time, through the design of the guide rod 52 and the annular lifting groove 411, the lifting sleeve 4 can move up and down reciprocally under the guidance of the fixed block 51 and the guide rod 52. This design allows the detachable stirring component 6 to not only rotate around the central shaft 2, but also work at different height levels, thereby achieving a more comprehensive and efficient stirring effect.

[0033] Specifically, the detachable stirring component 6 includes an arc-shaped fixing plate 61, a telescopic sleeve 62, and a scraper 63. The inner wall of the arc-shaped fixing plate 61 is tightly attached to the outer wall of the central cylinder 42. The opposing arc-shaped fixing plates 61 are fixedly connected to the outside of the central cylinder 42 by fastening bolts. The telescopic sleeve 62 is fixedly installed on the outer wall of the arc-shaped fixing plate 61 and the scraper 63 is provided at its end. The outer wall of the scraper 63 is arc-shaped and slides in contact with the inner wall of the reaction chamber 1.

[0034] The inner wall of the arc-shaped fixing plate 61 is designed to fit tightly against the outer wall of the central cylinder 42. The two opposing arc-shaped fixing plates 61 are fixed to the central cylinder 2 by fastening bolts, ensuring the stable installation and easy disassembly of the detachable stirring component 6. This not only ensures that the detachable stirring component 6 can be firmly attached to the lifting sleeve 4, but also facilitates cleaning or replacement. The telescopic sleeve 62 is the part that connects the arc-shaped fixing plate 61 and the scraper 63. It is fixedly installed on the outer wall of the arc-shaped fixing plate 61, and a scraper 63 is provided at its end. The scraper 63 is the part that directly contacts the inner wall of the reaction chamber 1. Its outer wall surface is arc-shaped so that it can slide tightly against the inner wall of the reaction chamber 1. This helps to scrape off the material adhering to the inner wall of the reaction chamber 1 during the stirring process, prevents material accumulation, and also helps to improve mixing efficiency and uniformity.

[0035] Specifically, the telescopic sleeve 62 includes a telescopic cylinder 621, a spring 622, a push block 623, and a telescopic rod 624. The telescopic cylinder 621 is fixedly installed on the outer wall of the arc-shaped fixed plate 61. The spring 622 is fixedly installed inside the telescopic cylinder 621, and the push block 623 is fixedly installed at the telescopic end of the spring 622. The push block 623 can only be movably installed inside the corresponding telescopic cylinder 621. The cross-section of the push block 623 is square. The telescopic rod 624 is fixedly installed at the end of the push block 623 away from the spring 622. The end of the telescopic rod 624 passes through the telescopic cylinder 621 and is fixedly installed with the scraper 63 by fastening bolts.

[0036] When the device is running, the servo motor 3 drives the central shaft 2 to rotate, which in turn drives the lifting sleeve 4 and all the stirring components 6 installed on it to rotate together. During this process, the spring 622 in the telescopic sleeve 62 will automatically adjust its length according to the pressure change or material resistance inside the reaction chamber 1. When the scraper 63 contacts the inner wall of the reaction chamber 1 or other obstacles, the resistance increases, and the push block 623 will move backward in the telescopic sleeve 621, compressing the spring 622, so that the telescopic rod 624 and the scraper 623 retract slightly. When the scraper 63 is no longer obstructed, the spring 622 returns to its original state, pushing the push block 623 forward, and the telescopic rod 624 and the scraper 63 extend out to continue to contact and clean the inner wall of the reaction chamber 1 on the scraper 63. This allows the telescopic rod 624 to extend and retract under the action of the spring 622 to adapt to different operating requirements.

[0037] Specifically, the feeding component 7 includes a feeding cylinder 71, a feeding valve 72, a conical feeding chamber 73, and a sealing cover 74. The feeding cylinder 71 is fixedly installed at the upper edge of the reaction chamber 1. The lower end of the feeding cylinder 71 extends through into the reaction chamber 1, and the upper end is fixedly installed with the conical feeding chamber 73. The feeding valve 72 is disposed on the side wall of the feeding cylinder 71. The upper end of the conical feeding chamber 73 is threadedly connected to the sealing cover 74. The discharging component 8 includes a discharging cylinder 81 and a discharging valve 82. The discharging cylinder 81 is fixedly installed at the lower edge of the reaction chamber 1. The upper end of the discharging cylinder 81 extends through into the reaction chamber 1, and the discharging valve 82 is disposed on the side wall of the discharging cylinder 81.

[0038] The feed valve 72 is located on the side wall of the feed cylinder 71 and is used to control the flow rate and timing of the material entering the reaction chamber 1. By adjusting the opening of the feed valve 72, the material supply speed can be precisely controlled to ensure the stability of the process. The conical feed hopper 73 is located at the upper end of the feed cylinder 71 and adopts a conical design to facilitate the smooth flow of material into the feed cylinder 71. The conical structure helps to reduce material accumulation and improve feeding efficiency. The sealing cover 74 is threadedly connected to the top of the conical feed hopper 73 to provide additional sealing protection to prevent external impurities from entering or material leakage. It can also be easily opened for cleaning or maintenance. The discharge cylinder 81 is fixedly installed at the lower edge of the reaction chamber 1 and its upper end extends through into the interior of the reaction chamber 1. The discharge cylinder 81 provides an outlet for the processed material to leave the reaction chamber 1.

[0039] Specifically, the reaction chamber 1 includes a cover 11, a body 12, a base 13, support legs 14, and a discharge plate 15. The cover 11, body 12, and base 13 are fixedly connected from top to bottom. The support legs 14 are arranged in a circular array at the lower end of the base 13. The discharge plate 15 is fixedly installed at the upper end of the base 13. The outer diameter of the discharge plate 15 is the same as the inner diameter of the body 12. A discharge port 151 is provided through the upper edge of the discharge plate 15. The discharge port 151 is connected to the discharge cylinder 81. A gentle slope 152 is provided on the discharge plate 15, which is inclined downward toward the discharge port 151.

[0040] After the dehydration process is completed, the treated coal tar or other materials will slide along the slope 152 to the discharge port 151 by gravity, and then be discharged through the discharge cylinder 81. This reduces the accumulation of materials on the inner wall of the box, improves the material discharge rate, and the presence of the slope 152 allows the materials to flow out more smoothly, avoiding blockage.

[0041] Specifically, a height positioning block 421 is fixedly installed on the outer wall of the central cylinder 42. The height positioning block 421 and the arc-shaped fixing plate 61 are arranged in a one-to-one correspondence. The inner arc surface of the arc-shaped fixing plate 61 is provided with a positioning groove, and the height positioning block 421 is located in the corresponding positioning groove.

[0042] The height positioning blocks 421 are fixedly installed on the outer wall of the central cylinder 42, and each positioning block 421 corresponds to a specific arc-shaped fixing plate 61. Their main function is to provide an accurate position reference point to ensure that the arc-shaped fixing plate 61 can be correctly installed in the predetermined position.

[0043] Working principle: The sealing cover 74 is opened, and the coal tar to be processed is added to the reaction chamber 1 through the conical feed hopper 73 and feed cylinder 71. The feed valve 72 is adjusted to control the speed and amount of material entering the reaction chamber 1. The servo motor 3 is started, driving the central shaft 2 to rotate. The edge protrusion 21 on the central shaft 2 causes the lifting sleeve 4 to rotate with the central shaft 2 and move up and down under the action of the reciprocating lifting component 5. The lifting sleeve 4 drives the detachable stirring component 6 installed on it to rotate and move up and down, forming a three-dimensional stirring mode to ensure uniform mixing of the coal tar in the reaction chamber. The scraper 63 slides close to the inner wall of the reaction chamber 1 to remove material adhering to the inner wall and prevent material accumulation. When the scraper 63 encounters… When resistance is encountered, the spring 622 inside the telescopic sleeve 62 is compressed, causing the scraper 63 to retract. When the resistance disappears, the spring 622 returns to its original state, pushing the scraper 63 to re-contact the inner wall of the reaction chamber, ensuring operational flexibility and adaptability. During the stirring process, the water in the coal tar is effectively separated. The treated coal tar flows through the gentle slope 152 on the discharge plate 15 to the discharge port 151 and is finally discharged through the discharge cylinder 81. The discharge valve 82 is used to control the discharge speed and timing of the treated material. When equipment maintenance or cleaning is required, the inspection plate 9 can be opened to inspect and repair the inside of the reaction chamber. The design of the detachable stirring component 6 facilitates disassembly and cleaning, reducing downtime.
