Description

Technical Field

[0001] This utility model relates to the field of lithium battery solid waste recycling technology, specifically a sintering device for solid waste recycling. Background Technology

[0002] Waste batteries and battery waste are classified as recyclable solid waste, which can be divided into waste lithium iron phosphate batteries, waste ternary lithium batteries, waste lithium cobalt oxide batteries, waste nickel-hydrogen batteries, waste fuel cells and other waste batteries generated in industrial production activities, as well as waste electrode sheets, waste cells, waste powder and slurry, and scraps generated in the battery production process. When recycling solid waste from lithium batteries, sintering is required. High-temperature sintering can separate the electrode material from the current collector. Through physical crushing, screening and other processes, the positive and negative electrode materials are enriched, which facilitates the subsequent extraction of valuable metals (such as copper, aluminum and other rare earth elements).

[0003] Existing Chinese patent CN211717170U, published on October 20, 2020, discloses a box-type sintering furnace, belonging to the technical field of sintering equipment. It includes a furnace body and a furnace opening on the side wall of the furnace body. A furnace door for closing the furnace opening is provided on the side wall of the furnace body. The height of the furnace door is greater than the height of the furnace body. A first worm gear is fixed to the upper surface of the furnace body, with the length direction of the first worm gear parallel to the height direction of the furnace door. At least one limiting rod is provided on the upper surface of the furnace body, with the length direction of the limiting rod parallel to the length direction of the first worm gear. A limiting block is sleeved on the limiting rod, and the side wall of the limiting block is fixedly connected to the inner wall of the furnace door. A reciprocating motor is provided on one side of the limiting block, and a second worm gear is provided between the reciprocating motor and the limiting block. The second worm gear is rotatably connected to the limiting block and engages with the first worm gear through the limiting block for transmission. The reciprocating motor drives the second worm gear to rotate. This invention achieves the effect of automatically opening and closing the furnace door to effectively prevent workers from being burned.

[0004] However, in actual use, the above-mentioned device uses a furnace body to store solid waste for sintering. The bottom of the solid waste is in contact with the bottom of the furnace body, which means that it cannot effectively and fully receive the temperature for sintering, resulting in a low efficiency in the sintering process.

[0005] Therefore, we propose a novel sintering device for solid waste recycling to solve the above-mentioned technical problems. Utility Model Content

[0033] Example 1

[0034] This embodiment provides a technical solution: a sintering device for solid waste recycling, such as... Figures 1-5 As shown, it includes a solid waste recycling sintering machine body, a solid waste recycling collection machine body, a uniform temperature sintering placement mechanism, and a sintering debris collection mechanism.

[0035] The solid waste recycling and collection body is fixedly connected to the lower end of the solid waste recycling sintering machine. This body collects materials that fall off during the sintering of lithium batteries. The uniform temperature sintering placement mechanism is fixedly connected to the middle of the solid waste recycling and collection body. Lithium battery solid waste can be placed on this mechanism for uniform temperature sintering. The sintering heat can heat the bottom of the placed lithium battery solid waste, making the sintering process more uniform and efficient. The sintering debris collection mechanism is rolled and sleeved on the inner side of the lower end of the solid waste recycling and collection body, making it easy to pull out and open. This mechanism collects the sintering materials that fall off the solid waste recycling and collection body, allowing for centralized collection and processing, making the process more efficient and convenient.

[0036] like Figure 1 and Figure 5As shown, the solid waste recycling sintering machine includes a sintering furnace box 5. The interior of the sintering furnace box 5 is hollow and can store lithium battery solid waste for sintering. Sintering combustion guns 4 are fixed to the inner sides of both ends of the sintering furnace box 5. The sintering combustion guns 4 can be ignited and sintered using natural gas. A smoke collection hood 2 is fixed to the upper end of the sintering furnace box 5. The sintering flue gas inside the sintering furnace box 5 can be effectively collected through the conical groove inside the smoke collection hood 2. A smoke discharge pipe 1 is fixed to the middle of the upper end of the smoke collection hood 2. The solid waste sintering flue gas collected by the smoke collection hood 2 can be discharged through the smoke discharge pipe 1. A furnace box sealing mechanism is installed in the middle of the front end of the sintering furnace box 5, which can effectively seal during sintering, effectively isolate and protect against temperature loss. The smoke discharge pipe 1 is connected to a purification tower to purify the flue gas.

[0037] The furnace box sealing mechanism includes an insulated door 3, which is filled with rock wool for effective insulation and protection. The insulated door 3 is movably connected to the sintering furnace box 5 via a door hinge 32 for easy opening and closing. The insulated door 3 is locked to the sintering furnace box 5 via a door lock 31, which can effectively seal and isolate the furnace during sintering.

[0038] During use, during sintering, personnel can place the solid waste from lithium batteries into the solid waste recycling sintering machine body, and place it on the uniform temperature sintering placement mechanism of the solid waste recycling collection machine body. The solid waste recycling collection machine body can collect the material that falls off during the sintering of lithium batteries inside the solid waste recycling sintering machine body. The sintering hot gas can heat the bottom of the solid waste placement of lithium battery solid waste, making the sintering more uniform and efficient. The sintering detachment collection mechanism can collect the sintering material that falls off the solid waste recycling collection machine body, and then collect and process it centrally. This makes the processing more efficient and convenient. The sintering detachment collection mechanism is rolled and sleeved on the inner side of the lower end of the solid waste recycling collection machine body, making it easy to pull out and clean.

[0039] Example 2

[0040] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-3As shown, to further better realize this utility model, the following configuration is specifically adopted: the solid waste recycling and collecting machine body includes a furnace box hollow base 6. The interior of the furnace box hollow base 6 is hollow, which facilitates the flow and fall of materials. The upper end of the furnace box hollow base 6 is fixedly connected to the sintering furnace box 5. The materials falling from the sintering inside the sintering furnace box 5 can be transported into the interior of the furnace box hollow base 6. The inner sides of both ends of the furnace box hollow base 6 are provided with air inlet slots 61 to facilitate the supply of gas for sintering. The lower end of the furnace box hollow base 6 is fixedly connected to a four-hole mounting base plate 6. 3. The hollow base 6 of the furnace box can be installed in a designated position by screws through the four-hole mounting base plate 63 at the lower end. The connection between the hollow base 6 of the furnace box and the four-hole mounting base plate 63 is provided with an ash collection trough 62, which facilitates the centralized collection of sintering materials. The hollow base 6 of the furnace box is fixedly connected to a uniform temperature sintering placement mechanism, which is convenient for personnel to place lithium battery solid waste for sintering. The hollow base 6 of the furnace box is fitted with a sintering debris collection mechanism through the ash collection trough 62. The sintering debris collection mechanism can effectively collect the materials in the ash collection trough 62.

[0041] The uniform temperature sintering placement mechanism includes a hollow partition 72. The hollow partition 72 is hollow inside to facilitate gas flow and transportation. The hollow partition 72 is sealed and fixed to the inner wall of the hollow base 6 of the furnace box, allowing for stable installation. Six through-hole ventilation slots 73 are opened on the inner side of the upper end of the hollow partition 72. Hot gas inside the hollow partition 72 can be discharged through the ventilation slots 73. An inverted V-shaped partition 7 is installed on the outer side of each ventilation slot 73. The discharged hot gas can heat the inverted V-shaped partition 7. Solid waste from lithium batteries is placed on the inverted V-shaped partition 7. The inverted V-shaped partition 7 heats the solid waste from lithium batteries. The state effectively reduces the contact area, and the gap between the two inverted V-shaped partitions 7 allows hot air to flow, enabling the sintering hot air to efficiently contact the bottom of the lithium battery solid waste. This allows for efficient contact sintering. The inverted V-shaped partitions 7 are fixed to the hollow partitions 72 for stable installation. The upper sides of the hollow partitions 72 are fixed with top-aligned hollow air intake heat plates 71. Holes are opened on the inner side of the hollow air intake heat plates 71 to facilitate the flow of hot air into the interior of the hollow partitions 72. The mesh blockage of the hollow air intake heat plates 71 can be cleaned by vacuuming during each sintering process.

[0042] A dust collection trough 74 is provided through the hollow partition 72 between the two inverted V-shaped partitions 7, so that the solid waste from the lithium battery can fall off effectively through the dust collection trough 74.

The collection tray 8 can be rolled and pulled out by the thirty-six rolling balls 83. A pull handle 82 is installed in the middle of the front end of the collection tray 8 by screws, which makes it easy for personnel to hold and pull out for cleaning.

[0045] The collecting tray 8 is rolled and sleeved in the ash collection trough 62 of the hollow base 6 in the furnace box by the rolling ball 83, so that it can be rolled and pulled stably.
