Description

Technical Field

[0001] This utility model relates to the field of lithium mica processing technology, and more specifically, to an energy-saving structure for a lithium mica drying device. Background Technology

[0002] Lepidolite, also known as lithium mica, is a lithium-rich layered silicate mineral and one of the important mineral resources for lithium extraction. Lepidolite drying is a crucial pre-processing step in the lithium battery new energy industry chain, from raw lepidolite ore to lithium extraction. Its core purpose is to efficiently, stably, and economically remove moisture from lepidolite concentrate to meet the stringent moisture content requirements of subsequent roasting and sulfate roasting processes. Given that lepidolite concentrate is typically in powder or fine granular form, the most mainstream and efficient drying equipment is the rotary kiln and the airflow dryer. The rotary kiln uses a long cylindrical structure and a feed plate to move the lepidolite, causing it to tumble and fully contact hot air for drying.

[0003] Most existing lepidolite drying devices have an open discharge structure. During use, the material is discharged through the discharge structure and hot air is released, resulting in a certain amount of heat loss. The lost heat can easily reduce the overall drying effect of lepidolite and affect the drying efficiency. At the same time, additional air heating is required, which can easily lead to some waste.

[0004] In summary, in order to address the issue of heat loss at the discharge point when using a lithium mica drying device, it is necessary to improve the sealing effect, reduce heat loss, and enhance the overall energy-saving effect of the equipment. Utility Model Content

[0005] The present invention provides an energy-saving structure for a lithium mica drying device, which aims to solve the problem that existing lithium mica drying devices, when in use, discharge material and exhaust hot air through the discharge structure, resulting in a certain amount of heat loss. The lost heat can easily reduce the overall drying effect of lithium mica and affect the drying efficiency of lithium mica.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving structure for a lithium mica drying device, including a mounting platform, a rotating tube for docking with a drying cylinder rotatably connected to the inner side of the mounting platform, a surrounding tube for assisting in sealing the discharge port fixed to one side of the mounting platform, mounting frames provided at both the front and rear ends of the surrounding tube, a rotating groove opened inside one side of the surrounding tube, a rotating platform for reducing heat loss provided outside one side of the surrounding tube, a connecting block fixed to one side of the rotating platform, and the rotating platform and the surrounding tube rotatably connected through the connecting block and the rotating groove.

[0007] In a preferred embodiment, a support platform is provided on the outer side of the mounting platform, and a mounting groove is provided on the inner side of the lower end of the support platform.

[0008] In a preferred embodiment, a connecting frame is installed on the outside of the mounting frame, a control pump is installed on the outside of the connecting frame, a connecting pipe is provided at the lower end of the control pump, and a heat exchange plate body is provided on the outside of the connecting pipe.

[0009] In a preferred embodiment, a support frame is fixedly connected to both the front and rear of one side of the rotating platform, and a rotating block is rotatably connected between the two support frames. A rotating seat is fixedly connected to both the front and rear of one side of the rotating platform, and a baffle plate is rotatably connected to the inner side of the rotating seat.

[0010] In a preferred embodiment, a first hydraulic push rod is installed on one side of the mounting slot, and a movable stage is fixedly connected to the output end of the first hydraulic push rod. The first hydraulic push rod is used to drive the movable stage to move along a predetermined path, and a rotating frame is rotatably connected to the inner side of the movable stage.

[0011] In a preferred embodiment, a second hydraulic push rod is installed on the inner side of the rotating frame, and a support block is fixedly connected to the output end of the second hydraulic push rod. The second hydraulic push rod is used to drive the support block to move along a predetermined path, and a limit frame is rotatably connected to the outer side of the support block.

[0012] In a preferred embodiment, a discharge pipe is provided on one side of the limiting frame, and a receiving pipe is installed on the other side of the limiting frame. The receiving pipe is slidably connected to the rotating block. A movable plate is slidably connected to the upper end of the receiving pipe, and a threaded rod is rotatably connected to the upper end of the movable plate. The threaded rod is threadedly connected to the limiting frame.

[0013] The beneficial effects of this utility model are as follows: This utility model supports the mounting platform with a support platform, connects to the discharge port of the rotary drying cylinder through a rotating pipe, and connects to the connecting block through a rotating groove. Thus, the overall sealing effect of the discharge port is improved by the mounting platform, the surrounding pipe, and the rotating platform. At the same time, the mounting frame directionally discharges hot air and positions and fixes the mounting frame, thereby cooperating with the control pump, connecting pipe, and heat exchange plate body to concentrate the dissipated hot air, and exchange heat through the heat exchange plate body and external equipment pipelines.

[0014] This invention uses a first hydraulic push rod to move the moving platform and rotating frame, facilitating the adjustment of the horizontal distance between the rotating frame and the rotating platform. A second hydraulic push rod and a support block drive the movement of the limiting frame, thereby coordinating with the moving platform and rotating frame to adjust the position and tilt angle of the limiting frame and the receiving pipe. During drying, the dried lithium mica sample contacts and is collected through the receiving pipe and discharged through the discharge pipe, allowing for easy observation of the drying effect. Simultaneously, a threaded rod drives the moving plate to facilitate the sealing of the receiving pipe, preventing material loss. Attached Figure Description

[0023] It should be noted that by connecting the rotating tube 2 to the discharge port of the rotary drying cylinder, and cooperating with the mounting platform 1, the surrounding tube 3 and the rotating platform 12, the overall sealing effect of the discharge port is improved. At the same time, the rotating tube 2 facilitates the mounting platform 1 to remain fixed, prevents the mounting frame 4 from deflecting, and ensures the normal operation of the drying cylinder.

[0024] It is worth noting that by connecting the rotating slot 5 to the connecting block 13, the independence between the surrounding pipe 3 and the rotating table 12 is improved, which facilitates the mutual rotation between the surrounding pipe 3 and the rotating table 12, ensuring normal operation and maintenance. Furthermore, the mounting bracket 4 directionally discharges hot air, facilitating heat recovery and circulation.

A baffle plate 17 is rotatably connected to the inner side of the rotating seat 16.

[0030] It should be noted that the rotating seat 16 facilitates the rotation of the rotating block 15, and at the same time, the rotating seat 16 facilitates the rotation of the baffle plate 17, thereby adapting to the tilt angle of the rotating block 15, reducing the overflow of heat, improving the overall heat preservation effect, and saving energy.

[0031] Refer to the instruction manual appendix Figure 5 A first hydraulic push rod 18 is installed on one side of the mounting slot 7. A movable stage 19 is fixedly connected to the output end of the first hydraulic push rod 18. The first hydraulic push rod 18 is used to drive the movable stage 19 to move along a predetermined path.

[0034] It should be noted that the second hydraulic push rod 21 and the support block 22 drive the limit frame 23 to move, thereby cooperating with the moving platform 19 and the rotating frame 20 to adjust the position and height of the limit frame 23.

At the same time, a damping rotating shaft is provided between the rotating seat 16 and the baffle plate 17 to facilitate positioning and resetting.

[0038] Working principle: First, the mounting platform 1 is supported by the support platform 6 and connected to the discharge port of the rotary drying cylinder through the rotating pipe 2. Then, the connecting block 13 is connected through the rotating groove 5, thereby improving the overall sealing effect of the discharge port through the mounting platform 1, the surrounding pipe 3 and the rotating platform 12.

Finally, the hot air is concentrated by the control pump 9, the connecting pipe 10 and the heat exchange plate body 11, and heat exchange is carried out through the heat exchange plate body 11 and the external equipment pipeline.

[0039] In use, firstly, the first hydraulic push rod 18 pushes the moving platform 19 and the rotating frame 20 to move, facilitating the adjustment of the horizontal distance between the rotating frame 20 and the rotating platform 12. Next, the second hydraulic push rod 21 and the support block 22 drive the limiting frame 23 to move, thereby cooperating with the moving platform 19 and the rotating frame 20 to adjust the position and tilt angle of the limiting frame 23 and the receiving pipe 25. Then, the dried lithium mica sample is contacted and collected through the receiving pipe 25 and discharged through the discharge pipe 24, facilitating the observation of the drying effect. Finally, the threaded rod 27 drives the moving plate 26 to move, facilitating the sealing of the receiving pipe 25 and preventing material loss.
