Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automatic unloading technology, specifically relating to a solid unloading device. Background Technology
[0002] Solid unloading devices are suitable for scenarios involving the transfer, collection, and distribution of additives in the lithium battery industry. They are indispensable equipment in the storage and transportation of sealed lithium salt tanks.
[0003] In most existing solid waste unloading processes, workers invert lithium salt containers and open the valves to unload the material, allowing it to flow under its own weight into the next process or into another lithium salt container. This process not only fails to guarantee a sealed operation, allowing the lithium salt to be contaminated by external impurities, but also results in material residue remaining on the inner wall of the inverted container, leading to material waste during unloading. Utility Model Content
[0004] The purpose of this utility model is to provide a solid unloading device, comprising:
[0005] The supporting structure includes a base, a column, and a connecting platform, wherein the connecting platform is stably installed on the base via the column;
[0006] The lifting mechanism is fixed to the column via a mounting bracket and connected to the connecting platform;
[0007] The linear guide assembly includes two sets of linear guides, which are respectively installed on the opposite surfaces of the column and the mounting bracket.
[0008] Preferably, it also includes a feeding channel, which is an inverted "Y" shaped structure embedded in the connecting platform, and is divided into a vertical stirring tube and a downwardly angled feeding tube.
[0009] Preferably, the lifting mechanism is assembled from a helical gear reducer motor and a bevel gear ball screw lifting platform, with both ends of the bevel gear ball screw lifting platform slidably mounted on the linear guide assembly.
[0010] Preferably, a flexible stirring device is installed on the bevel gear ball screw lifting platform. The bottom of the flexible stirring device is connected to a stirring reduction motor, and three PTFE flexible blades are bonded to the top and extend into the stirring tube.
[0011] Preferably, a shaft seal structure is provided on the surface of the rod below the PTFE flexible blade, and the shaft seal structure is a double-lip seal.
[0012] The beneficial effects of this utility model are:
[0013] The flexible stirring device and the double-lip sealing structure on the surface allow the lithium salt tank to be cleaned after the material inside the tank falls due to its own gravity, and the lithium salt adhering to the inside of the tank can also be cleaned up. At the same time, the entire unloading process is in a sealed state, which effectively prevents the lithium salt from being contaminated by external impurities.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] like Figures 1 to 4 As shown, this embodiment provides a solid unloading device, including: a support structure 1, which includes a base 101, a column 102, and a connecting platform 103. The connecting platform 103 is stably installed on the base 101 via the column 102 and is made of low-alloy carbon steel profile with a powder coating process to provide high strength and high rigidity structural support; a lifting mechanism 2, which is fixed to the column 102 via a mounting bracket 201 and connected to the connecting platform 103; and a linear guide assembly 3, which includes two sets of linear slide rails 301, respectively installed on the opposite surfaces of the column 102 and the mounting bracket 201.
[0025] It also includes a feeding channel 4, which is an inverted "Y" shaped structure embedded in the connecting platform 103, and is divided into a vertical stirring tube 401 and a downwardly angled feeding tube 402.
[0026] The lifting mechanism 2 is assembled from a helical gear reducer motor 202 and a bevel gear ball screw lifting platform 203. The drive end of the helical gear reducer motor 202 is connected to the screw in the bevel gear ball screw lifting platform 203. The two ends of the bevel gear ball screw lifting platform 203 are slidably mounted on the linear guide assembly 3, so that the bevel gear ball screw lifting platform 203 moves up and down along the linear guide assembly 3 under the drive of the helical gear reducer motor 202.
[0027] A flexible stirring device 5 is installed on the bevel gear ball screw lifting platform 203. The bottom of the flexible stirring device 5 is connected to a stirring reduction motor 501, and three PTFE flexible blades 502 are bonded to its top, extending into the stirring tube 401. A shaft seal structure 503 is provided on the surface of the rod below the PTFE flexible blades 502. The shaft seal structure 503 is a double-lip seal, which has a long service life and excellent sealing performance. It is interference-fitted with the internal space of the stirring tube 401, allowing the rod to slide relative to the middle of the shaft seal structure 503 during the lifting and lowering of the flexible stirring device 5. This does not affect the movement of the rod while effectively achieving a sealing effect. As the flexible stirring device 5 moves up and down along with the bevel gear ball screw lifting platform 203, the stirring reduction motor 501 also starts, causing the flexible stirring device 5 to rotate. As it rotates, the top PTFE flexible blades 502 are thrown off by inertia, thus efficiently cleaning the inner wall of the tank and quickly removing lithium salts adhering to the inner wall.
[0028] In summary, after the receiving tank of the next process is connected to the discharge pipe 402, the lithium salt tank is inverted and placed on top of the discharge channel 4. At this time, the flexible stirring device 5 is in its initial bottom position, the shaft seal structure 503 is in a sealed state with the stirring pipe 401, and the PTFE flexible blades 502 are compressed under the limiting effect of the pipe. At this time, the switch valve at the outlet of the lithium salt tank is opened, and the material enters the receiving tank along the discharge pipe 402 until the material in the lithium salt tank is emptied. When the material in the lithium salt tank stops falling, the bottom stirring reduction motor 501 starts, driving the flexible stirring device 5 to rotate, and gradually rises with the bevel gear ball screw lifting platform 203 under the drive of the gear reduction motor 202. When the PTFE flexible blade 502 passes through the outlet channel of the lithium salt tank and enters the tank, the PTFE flexible blade 502 will extend with inertia, and in the extended state, it can ensure that it can touch the inner wall of the tank. Therefore, as the gear ball screw lifting platform 203 rises and falls, the lithium salt adhering to the inner wall of the tank can be effectively cleaned, avoiding waste caused by material leakage during the lithium salt filling process.
