Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment equipment, specifically a heat treatment device for high specific energy phosphorus-based anode materials. Background Technology

[0002] A high-temperature sintering furnace is a device specifically designed for high-temperature sintering. Its internal temperature can reach very high levels. For high-energy phosphorus-based anode materials, high-temperature sintering furnaces can be used for sintering and heat treatment of the materials to improve their microstructure and properties.

[0003] A search revealed, for example, that Chinese utility model patent CN221246945U discloses a high-temperature sintering furnace for heat treatment, comprising a base plate, a high-temperature sintering furnace body, a waste gas treatment structure, and a filter structure. The high-temperature sintering furnace body is mounted on the upper surface of the base plate, and the waste gas treatment structure is located on the upper left side of the high-temperature sintering furnace body. The filter structure is located on the upper interior of the high-temperature sintering furnace body, and the filter screen can move within the snap-fit ​​grooves one and two, facilitating replacement of the filter screen. During the high-temperature treatment of metal powder, the generated waste gas is discharged from the outlet pipe under the control of an exhaust pump. The first and second waste gas filter layers filter the waste gas inside the high-temperature sintering furnace body, while the activated carbon adsorption layer adsorbs and sterilizes harmful substances inside the waste gas, preventing these harmful substances from polluting the air.

[0004] In this utility model patent, the processed material enters the high-temperature sintering furnace body through the feed pipe. The processed material is prone to accumulate inside the feed pipe, which can cause blockage and affect the normal operation and production efficiency of the sintering furnace. Moreover, the filter screen needs to be cleaned manually, which increases the difficulty of operation and time cost. Especially during the high-temperature sintering process, the filter screen is prone to accumulating a large amount of impurities and residues. Manual cleaning is not only laborious but may also pose safety hazards. Therefore, a heat treatment device for high specific energy phosphorus-based anode materials is proposed.

[0010] Furthermore, sprockets are fixedly installed on the outer surfaces of both the rotating rod and the movable rod, and a chain is installed between the two sprockets for transmission.

[0011] Furthermore, a guide block is fixedly installed on the left side of the screen, and a guide groove adapted to the guide block is opened on the left inner wall of the filter box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The high-energy-density phosphorus-based anode material heat treatment device in this embodiment includes a high-temperature sintering furnace body 1, a filter box 2 is provided on the top of the high-temperature sintering furnace body 1, a feed hopper 3 is provided on the top of the filter box 2, and an auxiliary mechanism 5 is provided inside the feed hopper 3.

[0023] The top of the feed hopper 3 is provided with a feed port 301, and a cover is provided on the feed port 301. By opening the cover, the high specific energy phosphorus-based negative electrode material is put into the feed hopper 3 through the feed port 301.

[0024] By setting a dredging rod 502 inside the feed hopper 3, the high-energy phosphorus-based negative electrode material entering the feed hopper 3 can be dredged by rotating the dredging rod 502, preventing it from accumulating and clogging inside, and ensuring smooth feeding.

[0025] By setting up a screen 503, it is convenient to filter the high-energy phosphorus-based anode material entering the feed hopper 3, ensuring the purity of the high-energy phosphorus-based anode material entering the high-temperature sintering furnace body 1. By setting up a knocking component 506, and with the cooperation of spring 504, guide block 505 and guide groove, the screen 503 is in a shaking state. This shaking not only helps to clean the impurities on the screen 503 in time and prevent blockage, but also ensures that the filtration efficiency of the screen 503 is always kept at a high level.

[0026] By setting a discharge port 201 on the right side of the filter box 2, the waste material blocked on the screen 503 is discharged from the discharge port 201 along the inclined surface of the screen 503. A sealing cover is set at the bottom of the discharge port 201. When it is necessary to discharge the waste material, the sealing cover is opened. During the sintering process, the sealing cover is blocked at the discharge port 201 to seal it.

[0027] The auxiliary mechanism 5 includes a box body 501. The box body 501 is fixedly installed on the top of the feed hopper 3. A clearing rod 502 extending into the feed hopper 3 is rotatably installed on the inner top wall of the box body 501. A screen 503 is installed inside the filter box 2. Four springs 504 are fixedly installed at the bottom of the screen 503. A striking component 506 is installed at the bottom of the screen 503. A power component 507 is installed on the left side of the striking component 506.

[0028] The striking component 506 includes a movable rod 61 and a cam 62. The rotation of the cam 62 continuously strikes the screen 503, thereby preventing the high-energy phosphorus-based negative electrode material from accumulating on the screen 503 and ensuring that the high-energy phosphorus-based negative electrode material is evenly distributed on the screen 503. At the same time, the shaking of the screen 503 accelerates the filtration speed and achieves the effect of automatic cleaning of the screen 503.

[0029] The power assembly 507 includes a motor 71, a rotating rod 72, a first bevel gear 73, a second bevel gear 74, a sprocket 75, and a chain 76. The motor 71 drives the rotating rod 72 to rotate. Under the meshing of the first bevel gear 73 and the second bevel gear 74, the unblocking rod 502 rotates to unblock the high-energy phosphorus-based negative electrode material. Under the transmission of the sprocket 75 and the chain 76, the striking assembly 506 is driven to strike the screen 503. The fixed plate 4 is provided to provide stable support for the rotating rod 72 and the movable rod 61.

[0030] When implementing this procedure, please follow these steps:

[0031] 1) First, the high-energy phosphorus-based negative electrode material enters the feed hopper 3 from the feed inlet 301 and falls onto the screen 503. At this time, the device is connected to an external power source and the motor 71 is started. Under the operation of the power component 507, the striking component 506 and the unblocking rod 502 are driven to rotate synchronously.

[0032] 2) Then the rotation of cam 62 causes screen 503 to shake up and down. Screen 503 slides up and down in guide groove through guide block 505. Under the extension and retraction of spring 504, screen 503 remains in a shaking state.

[0033] 3) The filtered high-energy phosphorus-based negative electrode material enters the interior of the high-temperature sintering furnace body 1 through the inlet for processing;

[0034] 4) The last impurities that are intercepted are discharged from the discharge port 201.

[0035] In summary, this high-energy-density phosphorus-based anode material heat treatment device effectively solves the problem of easy accumulation and blockage of high-energy-density phosphorus-based anode material inside the feed hopper 3 by setting up the unblocking rod 502. This design ensures smooth material feeding, improves production efficiency, and reduces equipment downtime caused by blockage.

[0036] Furthermore, the screen 503 effectively filters the materials entering the main body 1 of the high-temperature sintering furnace, ensuring the purity of the materials. At the same time, the screen 503 is continuously struck by the cam 62 in the striking component 506, combined with the extension and contraction of the spring 504, keeping the screen 503 in a shaking state, effectively preventing the accumulation of impurities on the screen 503 and realizing automatic cleaning of the screen 503. This not only improves the filtration efficiency but also reduces the cost and safety hazards of manual cleaning.
