Description

Technical Field

[0001] The utility model relates to the technical field of decomposition and distillation of carbon-containing materials, in particular to a cotton stalk electromagnetic heating rapid carbonization device. Background Art

[0002] Domestic and foreign research has shown that the ways to provide heat for the pyrolysis process include high-temperature gas heating, combustion material heating, electric furnace heating, and carbide combustion heating. However, electric furnace heating has a slow temperature rise, low thermal efficiency, and wastes energy. Other heating methods are highly polluting and difficult to control temperature. Utility Model Content

[0003] In order to solve the problem of low carbonization efficiency of existing devices, the utility model provides a cotton stalk electromagnetic heating rapid carbonization device, which provides heat for pyrolysis through an electromagnetic heating ring. During the rotation of the furnace body, it generates induced heat with the electromagnetic coil arranged outside the furnace body, which heats up quickly and is heated evenly, so that the cotton stalks are quickly carbonized.

[0004] The utility model provides a cotton stalk electromagnetic heating rapid carbonization device, comprising a furnace body for heating the cotton stalks, the furnace body having a feed inlet, a transmission mechanism disposed at one end of the furnace body away from the feed inlet, an electromagnetic heating ring disposed on the periphery of the furnace body, and the furnace body being rotated within the electromagnetic heating ring by the transmission mechanism. The electromagnetic heating ring is used to supply heat to the furnace body, which can rotate relative to the electromagnetic heating ring. During rotation, the furnace body generates induction heat with the electromagnetic coil, thereby accelerating the carbonization of the cotton stalks.

[0005] Furthermore, a rotating shaft is provided in the furnace body, and a spiral blade for feeding and discharging materials from the material inlet is welded on the periphery of the rotating shaft. The feeding and discharging of materials are achieved by rotating the spiral blade provided in the furnace body.

[0006] Furthermore, the transmission mechanism includes a fixed gear, a transmission gear, and a motor. The transmission gear is fixedly connected to the output shaft of the motor. The fixed gear is fixedly mounted at the end of the furnace body away from the inlet, and the fixed gear meshes with the transmission gear. The motor drives the transmission gear to rotate, which in turn drives the meshed fixed gear to rotate. Because the fixed gear is welded to the furnace body, it drives the furnace body to rotate, ensuring uniform heating.

[0007] Furthermore, a support base is provided at the bottom of the furnace body, comprising a base frame and rollers. The rollers are rotatably mounted on the base frame and roll in contact with the outer surface of the furnace body, with the rollers rotating in the same direction as the furnace body. The base frame with the rollers provides stable support for the furnace body without hindering its rotation.

[0008] Furthermore, extension rings are provided on both ends of the roller, the diameter of the extension rings being larger than the diameter of the roller, and a plurality of support rings are provided on the periphery of the furnace body, the support rings being placed between the extension rings on both ends of the roller. The extension rings at both ends of the roller secure the support rings, thereby limiting the position of the furnace body.

[0009] Further, the support ring is provided with two, two support rings are arranged at both ends of the furnace body respectively, and two rollers are arranged at the bottom of each support ring correspondingly. The support rings are arranged at the front and rear ends of the furnace body respectively, and good stability is achieved.

[0010] Further, one end of the furnace body provided with the transmission mechanism is provided with an air hole, and the air hole is connected with a tail gas treatment mechanism through a pipeline. The tail gas treatment mechanism is used for filtering tail gas generated in the carbonization process.

[0011] Further, the tail gas treatment mechanism comprises an air filter, the pipeline connected with the air hole is in communication with the air filter, and a roller bearing is arranged at the connection position of the pipeline and the furnace body. The pipeline can not rotate with the furnace body through the arrangement of the roller bearing.

PREFERRED EMBODIMENT

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In order to change the heating mode of traditional carbonization device and accelerate carbonization, a cotton stalk electromagnetic heating rapid carbonization device is designed. Figure 1 and 2 As shown, it includes a furnace body 1 for heating cotton stalks. The furnace body 1 has a material port 2. A transmission mechanism is provided at one end of the furnace body 1 away from the material port 2. An electromagnetic heating ring 3 is provided on the periphery of the furnace body 1. The furnace body 1 is rotated by the transmission mechanism and is arranged in the electromagnetic heating ring 3. The furnace body 1 is driven to rotate by the transmission mechanism, generating induction heat with the electromagnetic coil outside the furnace body 1. The electromagnetic heating ring 3 is fixed to the base frame 9 through a support column 16. The furnace body 1 is made of carbon steel with good strength and high temperature resistance. It can resist the corrosion of exhaust gas generated by the carbonization process to a certain extent. A furnace cover is also provided at the end of the furnace body 1, which seals the furnace body 1 to ensure that the carbonization process does not exchange air with the outside.

[0021] To drive the furnace body 1 to rotate and generate induction heat between the furnace body 1 and the external electromagnetic heating ring 3, the transmission mechanism includes a fixed gear 6, a transmission gear 7, and a motor 8. The transmission gear 7 is fixedly connected to the output shaft of the motor 8. The fixed gear 6 is fixedly arranged at the end of the furnace body 1 away from the material inlet 2 and meshes with the transmission gear 7. Because the motor 8 rotates at a high speed, a speed reducer can be installed between the motor 8 and the transmission gear 7 to reduce the speed. At the same time, the fixed gear welded at the end of the furnace body 1 is connected to the output gear of the speed reducer, further reducing the speed of the furnace body 1 through the gear ratio.

[0022] In order to achieve rolling support for the furnace body 1, a support base is provided at the bottom of the furnace body 1. The support base includes a base frame 9 and a roller 10. The roller 10 is rotatably mounted on the base frame 9 and is in rolling contact with the outer surface of the furnace body 1. The rotation direction of the roller 10 is consistent with the rotation direction of the furnace body 1. The furnace body 1 rotates under the drive mechanism, driving the roller 10 to rotate accordingly.

[0023] To ensure that the relative position of the furnace body 1 and the base frame 9 remains unchanged, extension rings 11 are provided on both end faces of the roller 10. The diameter of the extension ring 11 is larger than that of the roller 10. Several support rings 12 are provided on the periphery of the furnace body 1, positioned between the extension rings 11 on the end faces of the roller 10. The thickness of the support rings 12 is less than the spacing between the extension rings 11 on the end faces of the roller 10. The rolling cooperation between the support rings 12 and the roller 10 ensures stable support for the furnace body 1 without hindering the rotation of the furnace body 1.

[0024] In order to further ensure stable support for the furnace body 1, two support rings 12 are provided, one at each end of the furnace body 1, and two rollers 10 are provided at the bottom of each support ring 12. Two rollers 10 are provided at the front and rear ends of the furnace body 1, respectively, to provide good support stability.

[0025] One end of the furnace body 1, where the transmission mechanism is located, has an air hole connected to an exhaust gas treatment mechanism via a pipe 13. Exhaust gas generated during the carbonization process is transported through pipe 13 to the exhaust gas treatment mechanism for filtration and discharge. To prevent pipe 13 from rotating with the furnace body, a roller bearing 15 is installed at the air hole. This ball bearing 15 can withstand radial pressure, preventing interference between pipe 13 and furnace body 1.

[0026] The exhaust gas treatment mechanism includes an air filter 14. A pipe 13 connected to the air hole is connected to the air filter 14. A roller bearing 15 is provided at the connection between the pipe 13 and the furnace body 1. The air filter 14 removes suspended particulate matter, microorganisms, harmful gases, and other pollutants in the exhaust gas through physical filtration, thereby improving air quality.

[0027] like Figure 3 As shown, a rotating shaft 4 is provided in the furnace body 1, and a spiral blade 5 is welded to the outer periphery of the rotating shaft 4 for feeding and discharging materials from the material port 2. The rotating shaft 4 is rotatably arranged in the center of the furnace body 1 and drives the spiral blade 5 to rotate to complete the feeding and discharging of materials. A sealing cover is provided on the material port 2. When the furnace body 1 is rotated to the material port upward, material can be fed, and when the furnace body 1 is rotated to the material port downward, material can be discharged. The structure of the spiral blade 5 feeding and discharging materials in the horizontal carbonization device is relatively mature and is described in detail in the patent publication number CN110499166A, so it will not be repeated here.

[0028] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all of them will fall within the scope of protection of the present invention.
