Description

Technical Field

[0001] This invention belongs to the technical field of carbon anode production equipment, specifically relating to a carbon material baking equipment. Background Technology

[0002] Before carbon materials can be used as raw materials to produce related products, they need to be baked to remove moisture.

[0003] Chinese patent CN219776308U discloses a carbon material baking device, including a box body, and further including: a roller box, which is rotatably mounted on the box body; a heating device for heating the inside of the box body; a driving device for driving the roller box to rotate through a transmission structure; and a water tank, wherein the total mass of the water tank and water is equal to the total mass of the motor and transmission structure when the water tank is full, and the position of the water tank is symmetrical to the position of the transmission structure.

[0004] However, the above invention has the following shortcomings: In the existing carbon material baking process, most carbon materials are baked by drums. Drum baking can automatically feed materials, but the discharging process is time-consuming and labor-intensive, which reduces the baking efficiency of carbon materials. In addition, for drums with spiral stirring mechanisms, materials are easy to accumulate on the back side after stirring and rolling, resulting in low drying efficiency.

[0005] Meanwhile, Chinese patent CN114719581B discloses a carbon material baking device, including: a base; a mounting frame fixedly connected to the two ends of the upper surface of the base; a discharge pipe connected through to the lower end of the outer surface of one side of the mounting frame; and a feed pipe; a rolling mechanism is fixedly connected to the outer surface of the mounting frame near the center, which allows the carbon material to be tumbling during the baking process.

[0006] However, the above invention has the following shortcomings: the inclined heating plate set in the rolling mechanism will form an angle with the rolling mechanism. This angle will easily cause material jamming and accumulation. At the same time, the mechanism is also cumbersome to feed and discharge, and it is impossible to observe the degree of material drying. Each time the machine is stopped to feed and discharge, the internal heat loss of the equipment will be too large, which will indirectly increase the consumption of heating energy and increase the drying cost.

[0007] Therefore, this paper proposes a carbon material baking device. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1

[0022] like Figures 1 to 7As shown, this invention provides an improved carbon material baking device, including a housing 1, a spiral stirring mechanism, a heating mechanism, a base 4, and a monitoring device. The outer wall of the housing 1 is configured as an insulation layer 2, and the inner wall is configured as a heat-conducting layer 3. The spiral stirring mechanism, the heating mechanism, and the monitoring device are installed in the housing 1. The bottom of the housing 1 is mounted on the base 4. The inner cavity of the housing 1 is configured from left to right as a feeding preheating chamber 5 and a stirring and drying chamber 6. The spiral stirring mechanism further includes a main spiral stirring rod 7 rotatably installed in the inner cavity of the housing 1 and a secondary spiral stirring rod 8 rotatably installed on the upper side of the main spiral stirring rod 7 in the stirring and drying chamber 6. The heating mechanism... The structure also includes a heating plate A9, a heating plate B10, and a hot air heating mechanism. The heating plate A9 is located at the bottom of the housing 1, and the heating plate B10 is located at the top of the mixing and drying chamber 6. The hot air output end of the hot air heating mechanism is located on the main spiral stirring rod 7 and is connected to the hot air channel 11 inside the main spiral stirring rod 7. The left end of the main spiral stirring rod 7 is connected to a rotating joint 12 and is connected to the output end of the hot air blower (not shown in the figure) by the heat insulation pipe 13 on the left side of the rotating joint 12. The monitoring mechanism is installed on the housing 1 and is used to control the stirring speed, heating, feeding and discharging efficiency of the spiral stirring mechanism and to detect the humidity and air pressure in the housing 1.

[0023] Its effects are as follows: When using this device, the feeding speed can be controlled by the star-shaped feeding valve. Then, the material is stirred and preheated in the feeding preheating chamber 5. After being guided to the stirring and drying chamber 6, the material to be piled up will be squeezed into the upper part of the stirring and drying chamber 6, and then stirred and dispersed by the secondary spiral stirring rod 8. This achieves efficient stirring and heating. The hot air jet from the main spiral stirring rod 7 will heat the material from the inside while the stirring rod is stirring the material, and carry away the evaporated water vapor, thus improving the drying efficiency. Finally, when the drying is detected to be completed, the material can be discharged by opening the chamber door. After discharge, the material can be fed again. This device has a high degree of automation and high drying efficiency.

[0024] Furthermore, a feed inlet 14 is provided on the top right side of the housing 1, and a feed hopper (not shown in the figure) is connected above the feed inlet 14 via a star-shaped feed valve (not shown in the figure). A heat exchange mechanism (not shown in the figure) is connected to the right side of the housing 1 via an exhaust end.

[0025] Furthermore, the exhaust end also includes an insulated exhaust pipe 15 and a solenoid valve 16 installed on the insulated exhaust pipe 15; because hot air will be continuously input into the box 1, when the monitoring device detects that the air pressure of the box 1 reaches the limit of the equipment in the box 1, it can control the solenoid valve 16 to discharge hot air to relieve pressure. At the same time, this hot air can also carry away water vapor, and the heat discharged hot air can be collected by a heat exchange mechanism for reuse, thereby saving energy and reducing production costs.

[0026] Furthermore, the feeding preheating chamber 5 is cylindrical, and guide grooves (not shown in the figure) are provided on the front and rear sides of the feeding preheating chamber 5. This structure facilitates the main spiral stirring rod 7 to stir and guide the incoming material to the left. At the same time, the heating plate A9 below the feeding preheating chamber 5 and the hot air flow discharged to the right can preheat the incoming material, thereby accelerating the drying efficiency, while the guide grooves can be used to guide the hot air flow.

[0027] Furthermore, the bottom of the mixing and drying chamber 6 is set as a semi-cylindrical shape and the top is set as a rectangular shape. The bottom of the mixing and drying chamber 6 is provided with a discharge port and an electrically controlled chamber door 17 is installed inside the discharge port. The rectangular top of the chamber in this structure is to provide mixing space for the material guided to the left and avoid material accumulation. The electrically controlled chamber door 17 is designed to open the chamber door and discharge the material when the monitoring device detects that the humidity inside the chamber is low enough to indicate that the material has been dried.

[0028] Furthermore, the upper left side of the electrically controlled compartment door 17 is connected to the synchronous belt pulley mechanism A19 outside the housing 1 via a rotating shaft 18. The synchronous belt pulley mechanism A19 is connected to the drive end of the servo motor 20, which is fixedly installed on the left side of the housing 1.

[0029] Furthermore, the right side of the main spiral stirring rod 7 is connected to the drive end of the gearbox 22 via a synchronous belt pulley mechanism B21, and the right side of the gearbox 22 is connected to the drive end of the drive motor 23; this structure can provide power to the main spiral stirring rod 7.

[0030] Furthermore, the left side of the auxiliary spiral stirring rod 8 is connected to the left side of the main spiral stirring rod 7 via a synchronous belt pulley mechanism C24; this structure allows the auxiliary spiral stirring rod 8 to rotate together with the main spiral stirring rod 7 through the synchronous belt pulley mechanism, so there is no need to use multiple sets of drive motors 23, saving equipment costs.

[0031] Furthermore, the hot air output end adopts an exhaust nozzle 25 with a filter screen 26 installed on it; this structure can prevent material particles from entering the nozzle and causing blockage. Although very small particles may get stuck in the filter screen 26, the hot air and the friction caused by the rotation with the material will remove the particles on the filter screen 26, thus avoiding blockage.

[0032] Furthermore, the monitoring mechanism also includes a control panel 27, a processor 28, a display 29, control buttons 30, an alarm 31, a power interface 32, a pressure sensor (not shown in the figure), a humidity sensor (not shown in the figure), and a temperature sensor (not shown in the figure). The control panel 27 is installed on the outside of the housing 1, and the control panel 27 is equipped with the processor 28, the display 29, the control buttons 30, the alarm 31, and the power interface 32. The pressure sensor, humidity sensor, and temperature sensor are installed on the inside of the housing 1. The processor 28 is electrically connected to the display 29, the control buttons 30, the alarm 31, the power interface 32, the pressure sensor, the humidity sensor, the temperature sensor, the heating mechanism, the spiral stirring mechanism, and the electrically controlled compartment door 17.

[0033] Working principle of the invention: In operation, the material is fed into the device by controlling the feeding speed through a star-shaped feeding valve. The material is then stirred and preheated in the feeding preheating chamber 5. After being guided to the stirring and drying chamber 6, the material to be stored is squeezed into the upper part of the chamber and then dispersed by the secondary spiral stirring rod 8. This achieves efficient stirring and heating. Meanwhile, the hot air jet from the main spiral stirring rod 7 heats the material from within while it is being stirred, and carries away the evaporated water vapor, thus improving drying efficiency. Finally, when drying is complete, the material can be discharged by opening the chamber door. After discharge, the material can be fed again. This device has a high degree of automation and high drying efficiency.

[0034] In addition, because the device continuously supplies hot air into chamber 1, when the monitoring device detects that the air pressure in chamber 1 has reached the limit of the equipment in chamber 1, it can control the solenoid valve 16 to discharge hot air to relieve pressure. At the same time, this hot air can also remove water vapor, and the heat from the discharged hot air can be collected by a heat exchange mechanism for reuse, thereby saving energy and reducing production costs. The design of the feeding preheating chamber 5 facilitates the main spiral stirring rod 7 to stir and guide the incoming material to the left. At the same time, the heating plate A9 below the feeding preheating chamber 5 and the hot air flow discharged to the right can preheat the incoming material, thereby accelerating the drying efficiency. The guide channel can be used to guide the hot air flow. Stirring drying The rectangular top of chamber 6 is designed to provide mixing space for materials guided to the left, preventing material accumulation. The electrically controlled chamber door 17 is designed to open and discharge materials when the monitoring device detects that the humidity inside the chamber is low enough to indicate that the materials are dried. This device can make the auxiliary spiral stirring rod 8 rotate together with the main spiral stirring rod 7 through a synchronous belt pulley mechanism, so there is no need to use multiple drive motors 23, saving equipment costs. The filter screen 26 is designed to prevent material particles from entering the nozzle and causing blockage. Although very small particles may get stuck in the filter screen 26, the hot air and the friction caused by the rotation with the materials will remove the particles on the filter screen 26, thus avoiding blockage.
