Description

Technical Field

[0001] This utility model belongs to the field of lithium battery cathode material production technology, specifically relating to a lithium battery cathode material production device. Background Technology

[0002] Currently, the raw materials used to manufacture lithium battery cathode materials include lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, and ternary materials. All of these materials are inorganic compounds, and the production steps are basically the same. First, the raw material liquid or solid needs to be mixed, and then the mixed raw material liquid or solid is placed in a heating furnace for firing to form the material used to manufacture lithium battery cathode materials.

[0003] Currently available heating furnaces typically consist of a furnace body and a furnace frame inside the furnace. During firing, a loading frame for loading raw materials needs to be pushed into the furnace body from one side. When pushing the loading frame into the furnace body, the front end of the loading frame needs to be aligned with the storage layer of the furnace frame before it is pushed in. This alignment process usually wastes a lot of time, thus greatly affecting the efficiency of material loading.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a lithium battery cathode material production apparatus.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a lithium battery cathode material production device that can solve the problem of slow material loading efficiency in existing heating furnaces.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A lithium battery cathode material production apparatus includes: a furnace body, a furnace door, a guide assembly, and a placement rack mechanism.

[0009] Multiple heating rods are installed on the inner wall of the furnace body. The furnace door slides along the front end of the furnace body. A T-shaped groove is carved into the bottom of the furnace body. A T-shaped sliding rod, adapted to the T-shaped groove, is fixed to the bottom of the side wall of the furnace door near the furnace body. Multiple casters are installed at the bottom of the T-shaped sliding rod. The guide assembly is installed on the side walls of the furnace body and the furnace door.

[0010] The placement rack mechanism is installed on the furnace door and includes: a pair of crossbars, a pair of gantry frames, and multiple pairs of L-shaped supports. One end of each pair of crossbars near the furnace door is fixed to the bottom of the side wall of the furnace door, while the other end slides on the bottom wall inside the furnace body. Each pair of gantry frames is fixed to one of the crossbars, and multiple fixed shafts are evenly spaced within the two legs of each pair of gantry frames. The multiple pairs of L-shaped supports rotate on the multiple pairs of fixed shafts. An arc-shaped push rod is fixed to the far end of each pair of L-shaped supports, and a counterweight is fixed to each arc-shaped push rod. A first support block and a second support block are respectively provided at the bottom of each L-shaped support and on both sides of the fixed shafts.

[0011] In one embodiment of this utility model, a pair of first limiting blocks are fixed on the side wall of the T-shaped slide groove near the furnace door, and a pair of second limiting blocks are fixed on the side of the T-shaped slide rod away from the furnace door. By setting the first and second limiting blocks, with the second limiting block located at the end of the T-shaped slide rod away from the furnace door, when the furnace door drives the T-shaped slide rod to slide outward in the T-shaped slide groove, the second limiting block, when it adheres to the side wall of the first limiting block, represents the maximum distance the furnace door can open outward, while simultaneously preventing the T-shaped slide rod from completely sliding out of the T-shaped slide groove.

[0012] In one embodiment of this invention, a pair of auxiliary wheels are installed at the bottom end of the side wall of the furnace door away from the furnace body, and a pair of handles are fixed on the furnace door. The auxiliary wheels assist in the movement of the furnace door. The handles are used to pull or push the handles.

[0013] In one embodiment of this utility model, the guiding assembly includes a pair of guide sleeves and a pair of guide rods. The pair of guide sleeves are fixed to the two outer side walls of the furnace body and are located near the furnace door. The pair of guide rods slide on the pair of guide sleeves, and the ends of the pair of guide rods near the furnace door are fixed to the two outer side walls of the furnace door. By sliding the pair of guide rods within the pair of guide sleeves, the furnace door can be opened horizontally when slid outwards from the furnace body, preventing it from shifting after opening.

[0014] In one embodiment of this invention, a fixing head is fixed to the end of each pair of guide rods away from the furnace door, and a pair of reinforcing ribs are fixed between each pair of guide rods and the side wall of the furnace door. The fixing head serves as a limiting device; when the guide rod drives the fixing head to fit against the side wall of the guide sleeve, it represents the maximum opening degree of the furnace door, and at the same time, the second limiting block also fits against the side wall of the first limiting block. The pair of reinforcing ribs are used to strengthen the connection strength between the furnace door and the guide rods.

[0015] In one embodiment of this utility model, a sealing frame adapted to the furnace body opening is provided on the side of the furnace door near the furnace body. The sealing frame is inserted into the furnace body opening to increase the sealing between the furnace door and the furnace body. At the same time, a gantry frame near the furnace door is attached to the sealing frame, and the sealing frame is chiseled with a clearance groove for the L-shaped bracket and the arc-shaped push rod to rotate.

[0016] In one embodiment of this utility model, a slider is fixed to the bottom of each of the two crossbars at the end away from the furnace door. A pair of grooves are carved into the inner bottom wall of the furnace body, and the pair of sliders slide in the grooves respectively. The end of the crossbar away from the furnace door slides in the groove via the slider, thereby sliding on the inner bottom wall of the furnace body.

[0017] In one embodiment of this invention, a plurality of first pulleys are mounted on the bottom of a pair of sliders, and a plurality of second pulleys are mounted on both side walls of the pair of sliders. The use of multiple first and second pulleys reduces the frictional force on the sliders as they slide within the groove.

[0018] In one embodiment of this utility model, a first roller is installed at the end of the arc-shaped push rod away from the L-shaped bracket, and a second roller is installed at the end of the L-shaped bracket away from the arc-shaped push rod. The first roller is used to reduce the friction between the top of the arc-shaped push rod and the arc-shaped push rod when the top L-shaped bracket of the arc-shaped push rod pusher rotates. The second roller is used to reduce the friction between the end of the L-shaped bracket away from the arc-shaped push rod and the loading frame when the loading frame presses down to rotate the L-shaped bracket.

[0019] In one embodiment of this utility model, a third support block is provided at the bottom of the two pairs of L-shaped brackets at the bottom end, on the side of the fixed axis away from the first support block. When the side wall of one end of the L-shaped bracket near the arc-shaped push rod rests on the third support block, the other end of the L-shaped bracket forms a 45-degree angle with the horizontal plane, and its top end extends out of the gantry frame.

[0020] Compared with the prior art, the lithium battery cathode material production device of this utility model effectively improves the efficiency of loading materials into the heating furnace through relevant structural design. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] like Figures 1 to 7 As shown, a lithium battery cathode material production device according to one embodiment of the present invention includes: furnace body 1, furnace door 101, guide assembly and placement rack mechanism 2.

[0033] like Figures 1 to 7 As shown, multiple heating rods 102 are installed on the inner wall of the furnace body 1. The furnace door 101 slides along the front end of the furnace body 1. A T-shaped groove 104 is carved into the bottom of the furnace body 1. A T-shaped sliding rod 103, adapted to the T-shaped groove 104, is fixed to the bottom of the side wall of the furnace door 101 near the furnace body 1. Multiple casters 105 are installed at the bottom of the T-shaped sliding rod 103. Guide components are installed on both sides of the furnace body 1 and the furnace door 101.

[0034] The heating rod 102 is used to heat the interior of the furnace body 1. The furnace door 101 slides within a T-shaped groove 104 via a T-shaped slide bar 103, thus sliding at the front end of the furnace body 1. The furnace door 101 and the T-shaped slide bar 103 slide outwards via multiple moving wheels 105. The guide assembly ensures that the furnace door 101 slides horizontally when opening outwards from the furnace body 1, preventing the furnace door 101 from shifting after opening.

[0035] like Figures 1 to 7 As shown, the placement rack mechanism 2 is installed on the furnace door 101. The placement rack mechanism 2 includes: a pair of crossbars 201, a pair of gantry frames 202, and multiple pairs of L-shaped supports 208. One end of the pair of crossbars 201 near the furnace door 101 is fixed to the bottom of the side wall of the furnace door 101, and the other end slides on the bottom wall inside the furnace body 1. The pair of gantry frames 202 are respectively fixed to the pair of crossbars 201, and multiple fixed shafts 207 are fixed at equal intervals in the two legs of the pair of gantry frames 202. The multiple pairs of L-shaped supports 208 rotate on the multiple pairs of fixed shafts 207 respectively. An arc-shaped push rod 209 is fixed to the opposite end of each pair of L-shaped supports 208, and a counterweight 211 is fixed to each arc-shaped push rod 209. A first support block 212 and a second support block 213 are respectively provided at the bottom of the L-shaped supports 208 and on both sides of the fixed shafts 207.

[0036] In this system, a pair of horizontal bars 201 provide lateral support to the gantry frame 202, while the pair of gantry frames 202 provide longitudinal support to the raw material loading frame. The raw material loading frame is placed layer by layer between the pair of gantry frames 202, with both ends of the raw material loading frame resting on the two adjacent ends of the two pairs of L-shaped supports 208. The weight of the counterweight block 211 is used to drive the L-shaped support 208 to rotate around the fixed shaft 207 towards one side of the arc-shaped push rod 209. Additionally, a first support block 212 is used to support the end of the L-shaped support 208 away from the arc-shaped push rod 209, keeping this end horizontal and supporting the L-shaped support 208, thus enabling the L-shaped support 208 to support the raw material loading frame. The second support block 213 is used to limit the final position of the L-shaped bracket 208 rotating around the fixed shaft 207 towards the side of the arc-shaped push rod 209 driven by the counterweight block 211. When the side wall of the L-shaped bracket 208 close to the arc-shaped push rod 209 is attached to the second support block 213, the end of the L-shaped bracket 208 away from the arc-shaped push rod 209 just rotates into the gantry frame 202. Thus, when the raw material loading frame is placed from top to bottom, the upper L-shaped bracket 208 will not obstruct the downward placement of the raw material loading frame.

[0037] When in use, first pull the furnace door 101 out from the front end of the furnace body 1. When the furnace door 101 moves outward, it drives a pair of gantry frames 202 to move out of the furnace body 1 through a pair of crossbars 201. After the pair of gantry frames 202 move out of the furnace body 1, place the raw material loading frame from above the pair of gantry frames 202 downward between the pair of gantry frames 202. When placing the first raw material loading frame, the two pairs of L-shaped brackets 208 at the bottom end need to be rotated between the pair of gantry frames 202 so that the end of the L-shaped bracket 208 away from the arc-shaped push rod 209 rotates out of the gantry frame 202. Then, when the raw material loading frame is placed downward, after the bottom sides of both ends of the raw material loading frame contact the end of the L-shaped bracket 208 outside the gantry frame 202, press the L-shaped bracket 208 to rotate. When the L-shaped bracket 208 is placed on the first support block 212, the L-shaped bracket 208 can support the raw material loading frame.

[0038] As the L-shaped support 208 rotates, it drives the arc-shaped push rod 209 to rotate as well. During this rotation, the tip of the arc-shaped push rod 209 contacts the side wall of the top L-shaped support 208, pushing the top L-shaped support 208 to rotate, causing one end of the top L-shaped support 208 away from the arc-shaped push rod 209 to rotate out of the gantry 202. Then, the remaining raw material loading frames are placed, causing them to contact the L-shaped support 208 and rotate, thus mounting the frames. After all the raw material loading frames are installed in this way, the furnace door 101 can be pushed towards the furnace body 1. The furnace door 101, via a pair of crossbars 201, drives the raw material loading frames inside the furnace body 1. The furnace body 1 is then heated by the heating rod 102.

[0039] like Figures 1 to 7 As shown, a pair of first limiting blocks 106 are fixed on the side wall of the T-shaped slide 104 near the furnace door 101. A pair of second limiting blocks 107 are fixed on the side of the T-shaped slide rod 103 away from the furnace door 101. By setting the first limiting blocks 106 and the second limiting blocks 107, and with the second limiting block 107 located at the end of the T-shaped slide rod 103 away from the furnace door 101, when the furnace door 101 drives the T-shaped slide rod 103 to slide outward in the T-shaped slide 104, the second limiting block 107, when it is attached to the side wall of the first limiting block 106, represents the maximum distance the furnace door 101 can open outward, while preventing the T-shaped slide rod 103 from completely sliding out of the T-shaped slide 104. A pair of auxiliary wheels 112 are installed at the bottom end of the side wall of the furnace door 101 away from the furnace body 1, and a pair of handles 113 are fixed on the furnace door 101. The auxiliary wheel 112 assists in moving the furnace door 101. The handle 113 is used to pull or push the handle 113.

[0040] like Figures 1 to 7 As shown, the guiding assembly includes a pair of guide sleeves 108 and a pair of guide rods 109. The pair of guide sleeves 108 are fixed to the two outer side walls of the furnace body 1 and are located at one end near the furnace door 101. The pair of guide rods 109 slide on the pair of guide sleeves 108 respectively, and the ends of the pair of guide rods 109 near the furnace door 101 are fixed to the two outer side walls of the furnace door 101. By sliding the pair of guide rods 109 inside the pair of guide sleeves 108, the furnace door 101 can be opened horizontally when it slides outward from the furnace body 1, preventing the furnace door 101 from shifting after opening.

[0041] like Figures 1 to 7As shown, a pair of guide rods 109 are each fixed with a fixing head 110 at the end furthest from the furnace door 101. A pair of reinforcing ribs 111 are fixed between each pair of guide rods 109 and the side wall of the furnace door 101. The fixing head 110 serves as a limit; when the guide rod 109 drives the fixing head 110 to fit against the side wall of the guide sleeve 108, the furnace door 101 moves outward to its maximum opening degree. At the same time, the second limiting block 107 also fits against the side wall of the first limiting block 106. The pair of reinforcing ribs 111 are used to strengthen the connection between the furnace door 101 and the guide rods 109.

[0042] like Figures 1 to 7 As shown, a sealing frame 114 adapted to the opening of the furnace body 1 is provided on the side of the furnace door 101 near the furnace body 1. After the sealing frame 114 is inserted into the opening of the furnace body 1, the sealing between the furnace door 101 and the furnace body 1 is increased. At the same time, a gantry frame 202 near the furnace door 101 is attached to the sealing frame 114, and the sealing frame 114 is chiseled with a clearance groove for the L-shaped bracket 208 and the arc-shaped push rod 209 to rotate.

[0043] like Figures 1 to 7 As shown, a pair of crossbars 201 have sliders 203 fixed to their bottom ends away from the furnace door 101. A pair of grooves 203 are carved into the inner bottom wall of the furnace body 1, and the pair of sliders 203 slide within the grooves 203 respectively. The end of the crossbar 201 away from the furnace door 101 slides within the grooves 203 via the sliders 203, thus sliding against the inner bottom wall of the furnace body 1. Multiple first pulleys 205 are installed at the bottom of the pair of sliders 203, and multiple second pulleys 206 are installed on both side walls of the pair of sliders 203. By setting multiple first pulleys 205 and multiple second pulleys 206, the friction of the sliders 203 sliding within the grooves 203 is reduced.

[0044] like Figures 1 to 7 As shown, a first roller 210 is installed at the end of the arc-shaped push rod 209 away from the L-shaped bracket 208, and a second roller 215 is installed at the end of the L-shaped bracket 208 away from the arc-shaped push rod 209. The first roller 210 is used to reduce the friction between the top of the arc-shaped push rod 209 and the arc-shaped push rod 209 when the top L-shaped bracket 208 of the arc-shaped push rod 209 rotates. The second roller 215 is used to reduce the friction between the end of the L-shaped bracket 208 away from the arc-shaped push rod 209 and the loading frame when the loading frame presses down to rotate the L-shaped bracket 208. A third support block 214 is provided at the bottom of the two pairs of L-shaped brackets 208 at the bottom end and on the side of the fixed shaft 207 away from the first support block 212. When one end of the L-shaped bracket 208, which is close to the side wall of the arc-shaped push rod 209, rests on the third support block 214, the other end of the L-shaped bracket 208 forms a 45-degree angle with the horizontal plane, and its top end extends out of the gantry 202.

[0045] Working principle: When in use, first pull the furnace door 101 out from the front end of the furnace body 1. When the furnace door 101 moves outward, it drives a pair of gantry frames 202 to move out of the furnace body 1 through a pair of crossbars 201. After the pair of gantry frames 202 move out of the furnace body 1, place the raw material loading frame from above the pair of gantry frames 202 downward between the pair of gantry frames 202. When the first raw material loading frame is placed downward, the bottom sides of both ends of the raw material loading frame contact the L-shaped bracket 208 located outside the gantry frame 202, and press the L-shaped bracket 208 to rotate. When the L-shaped bracket 208 is placed on the first support block 212, the L-shaped bracket 208 can support the raw material loading frame.

[0046] Additionally, as the L-shaped support 208 rotates, it drives the arc-shaped push rod 209 to rotate as well. During this rotation, the first roller 210 at the top of the arc-shaped push rod 209 contacts the arc-shaped push rod 209 on its top L-shaped support 208 and the side wall of the top L-shaped support 208, pushing the top L-shaped support 208 to rotate. This causes the end of the top L-shaped support 208 away from the arc-shaped push rod 209 to rotate out of the gantry 202. The remaining raw material loading frames can then be placed.

[0047] When the raw material loading frame is removed from the L-shaped bracket 208, the L-shaped bracket 208 rotates towards the arc-shaped push rod 209 due to the gravity of the arc-shaped push rod 209 and the counterweight 211 on the arc-shaped push rod 209. The L-shaped bracket 208 will rotate until its side wall hits the top of the arc-shaped push rod 209 below it. When the raw material loading frame below is removed from the L-shaped bracket 208, the L-shaped bracket 208 below it will also rotate, and the arc-shaped push rod 209 above it will move away from the side wall of the L-shaped bracket 208. At this time, the L-shaped bracket 208 above will rotate again, and the end of the L-shaped bracket 208 away from the arc-shaped push rod 209 will be completely rotated into the gantry frame 202 so that it will not affect the removal of the raw material loading frame at the bottom.

[0048] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure.
