Description

Technical Field

[0001] This invention relates to the field of rotary kiln technology, specifically to an atomizing device for material deposition in a rotary kiln. Background Technology

[0002] A rotary kiln is a long, tubular, high-temperature heating device that can rotate continuously at low speed. The cylinder is installed at an angle and is driven by a motor to rotate continuously. The inside is circulated with high temperature and can be circulated with an inert atmosphere. It is used for calcining, pyrolysis, and vapor deposition of materials. It can also realize intermittent feeding and discharging processes under various atmosphere protection. It has the characteristics of excellent airtightness and high temperature uniformity. It is widely used in ceramics, electronics, chemical industry, new material research and development, and special materials.

[0003] When existing rotary kilns are used for material deposition, various liquefied carbon sources are introduced into the kiln through an atomization structure for reaction. However, the carbon sources in the atomized droplets are prone to uneven distribution within the kiln tube, resulting in low homogenization within the brick kiln. This can easily lead to a reduction in the deposition effect of the material within the kiln, thus affecting the production quality of the material. Summary of the Invention

[0004] The purpose of this invention is to provide an atomizing device for material deposition in rotary kilns, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: the atomizing device for material deposition in a rotary kiln includes a base, on which a kiln shell and a lifting module are disposed; on the kiln shell, a kiln tube and a driving module are disposed; on the kiln tube, an electric heating module is disposed; at the kiln tail of the kiln tube, an atomizing component, a waste gas purification module and a liquid carbon supply module are disposed; at the kiln head of the kiln tube, an inert gas supply module and a material receiving module are disposed; and the atomizing component is connected to the liquid carbon supply module. The kiln shell is equipped with cooling components and exhaust compensation components; The atomizing assembly includes a feed pipe, an atomizing nozzle, a lifting plate, a central tube, and spiral blades; A feed pipe is installed at the kiln tail of the kiln tube. One end of the feed pipe is connected to the liquid carbon supply module, and the other end of the feed pipe is equipped with an atomizing nozzle. A lifting plate is installed on the inner wall of the kiln tube, and a central tube is installed inside the kiln tube. The central tube is equipped with spiral blades.

[0006] When the liquid carbon supply module delivers various liquid carbons into the feed pipe, it sprays atomized carbon source droplets into the kiln tube through the atomizing nozzle. At the same time, when the drive module drives the kiln tube to rotate at a low speed, the kiln tube can drive the internal lifting plates, central tube and spiral blades to rotate synchronously. The rotation of the lifting plates helps to carry the material in the kiln tube to a high position, allowing the material to fall freely and form a material mound. Furthermore, the rotation of the central tube and spiral blades helps to thin the material layer, making it easier for the atomized carbon source droplets sprayed by the atomizing nozzle to penetrate the powder evenly, thereby improving the homogenization of the atomized carbon source in the kiln tube.

[0007] As a preferred technical solution, the cooling assembly includes a fan, a cooling pipe, a central connecting pipe, an air distribution component, an air distribution duct, a connecting pipe, an exhaust pipe, a rotating shaft, and a servo motor; A fan is installed on the base, and a cooling pipe is installed at the bottom of the kiln shell. A rotating shaft is rotatably installed inside the cooling pipe, and a servo motor is installed on the cooling pipe. The servo motor is connected to the rotating shaft, and multiple sets of cooling control switches are installed on the rotating shaft. The fan is connected to the central pipe through the cooling pipe. An air distribution pipe is installed inside the kiln shell through an air distribution component. The air distribution pipe is connected to the central pipe through a connecting pipe. An exhaust pipe is installed at the top of the kiln shell, and a temperature sensor is installed inside the exhaust pipe. The servo motor is electrically connected to the temperature sensor. After the gaseous phase deposition of the material in the kiln is completed, the fan is started, allowing airflow to enter the air distribution pipe through the cooling pipe and the central pipe, facilitating the air distribution pipe to cool the kiln tube. The airflow carrying heat can be discharged through the exhaust pipe. Furthermore, the servo motor can drive the cooling control switches to rotate through the rotating shaft, which can cool the airflow and ensure the cooling effect on the kiln tube. At the same time, by detecting the temperature of the discharged airflow through the temperature sensor, the operating power of the servo motor can be reduced according to the decrease in airflow temperature.

[0008] As a preferred technical solution, the air distribution component includes a drive motor, drive teeth, a fixed ring, a slide groove, a slider, and driven teeth; A drive motor is installed on one side of the kiln shell, and a drive gear is installed on the output shaft of the drive motor. Two fixed rings are symmetrically installed inside the kiln shell. A sliding groove is opened at the lower part of the fixed ring. The sliding groove is semi-circular, and a slider is slidably installed in the sliding groove. The sliders on both sides are connected by air distribution pipes. A driven gear is rotatably installed on the fixed ring near the drive gear. The driven gear is connected to the slider. The drive gear and the driven gear mesh. The drive motor is electrically connected to a temperature sensor. When cooling the kiln tube, the drive motor is started, causing the drive motor to drive the drive gear to rotate. Through the meshing of the drive gear and the driven gear, the driven gear can drive the slider to move back and forth in the sliding groove, thereby causing the slider to drive the air distribution pipe to move back and forth synchronously. This helps to improve the cooling effect of the air distribution pipe on the kiln tube. At the same time, the high, medium, and low temperatures of the exhaust airflow detected by the temperature sensor can control the speed of the drive motor driving the drive gear to gradually decrease.

[0009] As a preferred technical solution, both ends of the slide are equipped with reversing triggers. The reversing triggers control the direction of the drive motor to drive the drive teeth. When the slider moves along the slide to one end and contacts the reversing trigger, the reversing trigger can control the rotation direction of the drive motor to change. This cycle repeats, thereby realizing the reciprocating movement of the slider in the slide, which in turn ensures the reciprocating cooling of the kiln tube by the air distribution pipe.

[0010] As a preferred technical solution, the cooling control unit includes a fixed sleeve, a fixed cooling element, a miniature electric push rod, a connecting ring, a rotating sleeve, a driven cooling element, a drive shaft, and a curved track; A fixed sleeve is fixedly fitted onto the rotating shaft. Multiple fixed cooling elements are mounted in a circular array on the fixed sleeve. A miniature electric actuator is mounted on one side of the fixed sleeve. A connecting ring is mounted on the miniature electric actuator, and a rotating sleeve is rotatably connected to the connecting ring. The rotating shaft passes through the connecting ring and the rotating sleeve. Multiple driven cooling elements are mounted in a circular array on the rotating sleeve. The fixed cooling elements and driven cooling elements are the same size and correspond one-to-one. A drive shaft is mounted on the inner wall of the rotating sleeve. The rotating shaft has multiple sets of curved tracks, and the drive shaft slides through the corresponding curved tracks. The miniature electric actuator is electrically connected to a temperature sensor. When the temperature sensor detects the temperature of the exhaust airflow, the extension distance of the miniature electric actuator can be gradually reduced according to the high, medium, or low temperature of the exhaust airflow. When the miniature electric actuator extends, it can drive the rotating sleeve to move synchronously through the connecting ring. During the movement, the rotating sleeve rotates at a corresponding angle through the squeezing force of the drive shaft by the curved channel, thereby realizing the degree of misalignment between the fixed cooling element and the driven cooling element. In this way, the cooling effect on the incoming airflow can be gradually reduced according to the high, medium, or low temperature of the exhaust airflow.

[0011] As a preferred technical solution, in the initial state, the fixed cooling plate and the driven cooling plate in the same group are flush, and when the rotating sleeve rotates, the maximum included angle between the cooling plate and the driven cooling plate in the same group is 30°.

[0012] As a preferred technical solution, the exhaust compensation component includes an intake end ring, a slide rail, a transmission block, a cover plate, a slide channel, and an air port; An air inlet ring is installed at the lower end of each exhaust pipe. A slide rail is installed on the top of the kiln shell, and a transmission block is slidably mounted on the slide rail. A cover plate is installed on the transmission block, and a slide channel is opened on the side of the cover plate near the inner wall of the kiln shell. The air inlet ring and the slide channel are in sliding fit. Multiple air ports are opened in the slide channel, and the diameters of the multiple air ports gradually increase. The air port with the largest diameter is consistent with the air inlet ring. When the exhaust pipe discharges hot air from the kiln shell, the temperature sensor can control the movement distance of the transmission block on the slide rail according to the high, medium, and low temperature of the discharged air. This allows the transmission block to drive the cover plate to move synchronously, and the overlap between the air ports on the slide channel and the air inlet ring gradually decreases. This is beneficial for high-temperature rapid exhaust, medium-temperature reduced exhaust, and low-temperature slow exhaust in the kiln shell, thereby achieving cooling stability of the kiln tube.

[0013] As a preferred technical solution, the included angle of the mist sprayed by the atomizing nozzle is less than or equal to 18°.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This application, through the design of a central tube and spiral blades, utilizes the rotation of the central tube and spiral blades to thin the material layer, facilitating the uniform penetration of atomized carbon source droplets sprayed from the atomizing nozzle into the powder, thereby improving the homogenization of the atomized carbon source within the kiln tube. In this application, by detecting the temperature of the exhaust airflow using a temperature sensor, the operating power of the servo motor can be reduced as the airflow temperature decreases.

[0015] In this application, the high, medium and low energy of the exhaust air temperature detected by the temperature sensor are used to control the speed of the drive motor and drive teeth to gradually decrease, thereby controlling the reciprocating frequency of the air distribution duct.

[0016] In this application, the extension distance of the miniature electric push rod can be gradually reduced according to the high, medium, and low temperatures of the exhaust airflow, thereby achieving the degree of misalignment between the fixed and driven cooling plates, and thus gradually reducing the cooling effect on the incoming airflow according to the high, medium, and low temperatures of the exhaust airflow.

[0017] In this application, the movement distance of the transmission block on the slide rail can be controlled according to the high, medium and low temperature of the exhaust gas, and the overlap between the air inlet and the air inlet end ring can be gradually reduced. This is beneficial for high-temperature rapid exhaust, medium-temperature reduced exhaust, and low-temperature slow exhaust in the kiln shell 2, thereby achieving cooling stability of the kiln tube.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Figures 1-7As shown, the present invention provides a technical solution for an atomizing device for material deposition in a rotary kiln. The atomizing device for material deposition in a rotary kiln includes a base 1, a kiln shell 2 and a lifting module 4 are provided on the base 1, a kiln tube 3 and a drive module 5 are provided on the kiln shell 2, an electric heating module is provided on the kiln tube 3, an atomizing component 8, a waste gas purification module and a liquid carbon supply module are provided at the kiln tail 6 of the kiln tube 3, and an inert gas supply module and a material receiving module are provided at the kiln head 7 of the kiln tube 3. The atomizing component 8 is connected to the liquid carbon supply module. The kiln shell 2 is equipped with a cooling assembly 9 and an exhaust compensation component 11; The atomizing assembly 8 includes a feed pipe 81, an atomizing nozzle 82, a lifting plate 83, a central tube 84, and a spiral blade 85; A feed pipe 81 is installed at the kiln tail 6 of the kiln tube 3. One end of the feed pipe 81 is connected to the liquid carbon supply module, and the other end of the feed pipe 81 is equipped with an atomizing nozzle 82. A lifting plate 83 is installed on the inner wall of the kiln tube 3, and a central tube 84 is installed inside the kiln tube 3. A spiral blade 85 is installed on the central tube 84.

[0022] When the liquid carbon supply module delivers various liquid carbons into the feed pipe 81, it sprays atomized carbon source droplets into the kiln tube 3 through the atomizing nozzle 82. At the same time, when the drive module 5 drives the kiln tube 3 to rotate at a low speed, the kiln tube 3 can drive the internal lifting plate 83, central tube 84 and spiral blade 85 to rotate synchronously. The rotation of the lifting plate 83 helps to carry the material in the kiln tube 3 to a high position, allowing the material to fall freely and form a material mound. Furthermore, the rotation of the central tube 84 and spiral blade 85 helps to thin the material layer, making it easier for the atomized carbon source droplets sprayed by the atomizing nozzle 82 to penetrate the powder evenly, thereby improving the homogenization of the atomized carbon source in the kiln tube 3.

[0023] The cooling assembly 9 includes a fan 91, a cooling pipe 92, a central connecting pipe 93, an air distribution component 94, an air distribution duct 95, a connecting pipe 96, an exhaust pipe 97, a rotating shaft 98, and a servo motor 99. A fan 91 is mounted on the base 1. A cooling pipe 92 is mounted on the bottom of the kiln shell 2. A rotating shaft 98 is rotatably mounted inside the cooling pipe 92, and a servo motor 99 is mounted on the cooling pipe 92. The servo motor 99 is connected to the rotating shaft 98. Multiple cooling control switches 10 are installed on the rotating shaft 98. The fan 91 is connected to the central connecting pipe 93 through the cooling pipe 92. An air distribution pipe 95 is installed inside the kiln shell 2 through an air distribution component 94. The air distribution pipe 95 is connected to the central connecting pipe 93 through a connecting pipe 96. An exhaust pipe 97 is mounted on the top of the kiln shell 2. A temperature sensor is installed inside the exhaust pipe 97. The servo motor 99 is connected to the temperature sensor. Electrical connection: After the gaseous deposition of materials in the kiln is completed, the airflow is allowed to enter the air distribution pipe 95 through the cooling pipe 92 and the central pipe 93 by starting the fan 91. This facilitates the cooling of the kiln tube 3 by the air distribution pipe 95. The airflow carrying heat can be discharged through the exhaust pipe 97. In addition, the servo motor 99 can drive the cooling control device 10 to rotate through the rotating shaft 98, which can cool the airflow and ensure the cooling effect on the kiln tube 3. At the same time, the temperature of the discharged airflow can be detected by the temperature sensor, and the operating power of the servo motor 99 can be reduced according to the decrease of the airflow temperature.

[0024] The air distribution component 94 includes a drive motor 941, a drive gear 942, a retaining ring 943, a slide groove 944, a slider 945, and a driven gear 946; A drive motor 941 is installed on one side of the kiln shell 2. A drive gear 942 is installed on the output shaft of the drive motor 941. Two fixed rings 943 are symmetrically installed inside the kiln shell 2. A sliding groove 944 is opened at the lower part of the fixed ring 943. The sliding groove 944 is semi-circular. A slider 945 is slidably installed in the sliding groove 944. The two sliders 945 are connected by an air distribution pipe 95. A driven gear 946 is rotatably installed on the fixed ring 943 near the drive gear 942. The driven gear 946 is connected to the slider 945. The drive gear 942 meshes with the driven gear 946. The drive motor 941 is electrically connected to the temperature sensor. When cooling the kiln tube 3, the drive motor 941 is started, causing the drive gear 942 to rotate. Through the meshing of the drive gear 942 and the driven gear 946, the driven gear 946 can drive the slider 945 to reciprocate within the slide groove 944, thereby causing the slider 945 to drive the air distribution pipe 95 to reciprocate synchronously. This helps to improve the cooling effect of the air distribution pipe 95 on the kiln tube 3. At the same time, the high, medium, and low temperatures of the exhaust airflow detected by the temperature sensor can control the speed of the drive motor 941 driving the drive gear 942 to gradually decrease.

[0025] Both ends of the slide 944 are equipped with reversing triggers. The reversing triggers control the drive motor 941 to drive the drive gear 942 to rotate. When the slider 945 moves along the slide 944 to one end and contacts the reversing trigger, the reversing trigger can control the rotation direction of the drive motor 941 to change. This cycle repeats, thereby enabling the slider 945 to move back and forth in the slide 944, which in turn ensures the reciprocating cooling of the kiln tube 3 by the air distribution pipe 95.

[0026] The refrigeration control unit 10 includes a fixed sleeve 1001, a fixed refrigeration element 1002, a miniature electric push rod 1003, a connecting ring 1004, a rotating sleeve 1005, a driven refrigeration element 1006, a drive shaft 1007, and a curved track 1008. A fixed sleeve 1001 is fixedly fitted onto the rotating shaft 98. Multiple fixed cooling elements 1002 are mounted in a circular array on the fixed sleeve 1001. A miniature electric push rod 1003 is mounted on one side of the fixed sleeve 1001. A connecting ring 1004 is mounted on the miniature electric push rod 1003. A rotating sleeve 1005 is rotatably connected to the connecting ring 1004. The rotating shaft 98 passes through the connecting ring 1004 and the rotating sleeve 1005. Multiple driven cooling elements 1006 are mounted in a circular array on the rotating sleeve 1005. The fixed cooling elements 1002 and the driven cooling elements 1006 are the same size and correspond one-to-one. A drive shaft 1007 is mounted on the inner wall of the rotating sleeve 1005. The rotating shaft 98 has multiple sets of curved tracks 1008, and the drive shaft 1007 slides through the corresponding tracks. Inside the curved channel 1008, the miniature electric push rod 1003 is electrically connected to the temperature sensor. When the temperature sensor detects the temperature of the exhaust airflow, it can control the extension distance of the miniature electric push rod 1003 to gradually decrease according to the high, medium, and low temperatures of the exhaust airflow. When the miniature electric push rod 1003 extends, it can drive the rotating sleeve 1005 to move synchronously through the connecting ring 1004. During the movement, the rotating sleeve 1005 rotates at a corresponding angle through the squeezing force of the drive shaft 1007 by the curved channel 1008, thereby realizing the degree of misalignment between the fixed cooling plate 1002 and the driven cooling plate 1006. In this way, the cooling effect on the incoming airflow can be gradually reduced according to the high, medium, and low temperatures of the exhaust airflow.

[0027] In the initial state, the fixed cooling element 1002 and the driven cooling element 1006 in the same group are flush. When the rotating sleeve 1005 rotates, the maximum angle between the fixed cooling element 1002 and the driven cooling element 1006 in the same group is 30°.

[0028] The exhaust compensation component 11 includes an intake end ring 1101, a slide rail 1102, a transmission block 1103, a cover plate 1104, a slide rail 1105, and an air port 1106. An air inlet ring 1101 is installed at the lower end of the exhaust pipe 97. A slide rail 1102 is installed on the top of the kiln shell 2. A transmission block 1103 is slidably installed on the slide rail 1102. A cover plate 1104 is installed on the transmission block 1103. A slide channel 1105 is opened on the side of the cover plate 1104 near the inner wall of the kiln shell 2. The air inlet ring 1101 and the slide channel 1105 are in sliding fit. Multiple air ports 1106 are opened in the slide channel 1105. The diameter of the multiple air ports 1106 gradually increases. The largest diameter air port 1106 is... With the intake end ring 1101 aligned, when the exhaust pipe 97 discharges the hot airflow from inside the kiln shell 2, the temperature sensor can control the movement distance of the transmission block 1103 on the slide rail 1102 according to the high, medium, and low temperatures of the discharged airflow. This allows the transmission block 1103 to drive the cover plate 1104 to move synchronously, gradually reducing the overlap between the air port 1106 on the slide rail 1105 and the intake end ring 1101. This facilitates high-temperature rapid exhaust, medium-temperature reduced exhaust, and low-temperature slow exhaust within the kiln shell 2, thereby achieving stable cooling of the kiln tube 3.

[0029] The included angle of the mist sprayed by the atomizing nozzle 82 is less than or equal to 18°.

[0030] The lifting module 4, drive module 5, electric heating module, exhaust gas purification module, liquid carbon supply module, inert gas supply module, and material receiving module mentioned in this application are all prior art, and therefore will not be elaborated upon in this application description.

[0031] Working principle of the invention: When the liquid carbon supply module delivers various liquid carbons into the feed pipe 81, it sprays atomized carbon source droplets into the kiln tube 3 through the atomizing nozzle 82. At the same time, when the drive module 5 drives the kiln tube 3 to rotate at a low speed, the kiln tube 3 can drive the internal lifting plate 83, central tube 84 and spiral blade 85 to rotate synchronously. The rotation of the lifting plate 83 helps to carry the material in the kiln tube 3 to a high position, allowing the material to fall freely and form a material mound. Furthermore, the rotation of the central tube 84 and spiral blade 85 helps to thin the material layer, making it easier for the atomized carbon source droplets sprayed by the atomizing nozzle 82 to penetrate the powder evenly, thereby improving the homogenization of the atomized carbon source in the kiln tube 3.

[0032] After the gaseous deposition of materials in the kiln is completed, the blower 91 is started, allowing airflow to enter the air distribution pipe 95 through the cooling pipe 92 and the central pipe 93, facilitating the cooling of the kiln tube 3 by the air distribution pipe 95. The drive motor 941 is started, and through the meshing of the drive gear 942 and the driven gear 946, the driven gear 946 drives the slider 945 to reciprocate within the slide groove 944, thereby causing the slider 945 to drive the air distribution pipe 95 to reciprocate synchronously. Furthermore, through the micro electric push rod 1003, the rotating sleeve 1005 is driven to move synchronously through the connecting ring 1004. During the movement, the rotating sleeve 1005 rotates at a corresponding angle due to the squeezing force of the drive shaft 1007 by the curved channel 1008, thereby achieving the degree of misalignment between the fixed cooling plate 1002 and the driven cooling plate 1006. This allows the cooling effect on the incoming airflow to be gradually reduced according to the high, medium, and low temperatures of the discharged airflow.

[0033] When the exhaust pipe 97 discharges the hot airflow from the kiln shell 2, the temperature sensor can control the movement distance of the transmission block 1103 on the slide rail 1102 according to the high, medium and low temperature of the discharged airflow. This allows the transmission block 1103 to drive the cover plate 1104 to move synchronously, so that the overlap between the air port 1106 on the slide rail 1105 and the air inlet ring 1101 gradually decreases. This is beneficial for high-temperature rapid exhaust, medium-temperature reduced exhaust, and low-temperature slow exhaust in the kiln shell 2, thereby achieving cooling stability of the kiln tube 3.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
