Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste battery recycling smelting, in particular to a smelting furnace for waste battery recycling. BACKGROUND

[0002] Waste battery recycling is an important resource recycling process, aiming to recover valuable metals in batteries and reduce environmental pollution. Waste batteries contain many harmful substances and valuable metal elements such as lead, lithium, cobalt, nickel, manganese, cobalt, etc. These metals can be extracted and reused. Lithium batteries are the most commonly used type of battery at present and are widely used in consumer electronics, energy storage and electric vehicles. Since lithium batteries contain rich valuable metals (such as lithium, cobalt, nickel, etc.), the recycling of lithium batteries is crucial for resource utilization and environmental protection. The recycling of waste lithium batteries usually goes through several stages: waste batteries are collected and classified by type; the battery shell is broken and then the plastic shell and other non-metallic parts are removed; the metal elements in the waste battery are extracted by smelting; in the recycling process of waste lithium batteries, the smelting furnace is an important equipment. The smelting furnace melts the metal by high temperature heating to achieve the purpose of separation and recovery.

[0003] In the smelting process of waste batteries, due to the different forms of metals, the existing smelting process usually pours the crushed metal mixture into the smelting furnace for smelting. This "one-pot smelting" method causes the granular metal to melt faster due to its small size, usually starting to melt in the early stage of smelting, while the blocky metal melts relatively slowly due to its large size and slow heat transfer. The melting difference of different forms of metals in the smelting furnace leads to temperature non-uniformity. The granular metal melts first and may be overheated, causing oxidation and evaporation loss, resulting in loss of valuable metals. The melting of blocky metal lags behind, which may not be completely melted, resulting in local temperature being too low and reducing the quality of metal recovery.

[0004] In addition, the existing "one-pot smelting" method also causes uneven heat distribution due to the inability to stir the materials in the furnace, which cannot completely melt all the metals, further affecting the recovery rate and effect. SUMMARY

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objectives, features and advantages of the present application more apparent and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 and Figure 2The application provides a technical scheme: a smelting furnace for waste battery recycling, which comprises an outer furnace body 1 and two left-right symmetrical furnace covers 2 slidingly connected to the upper part of the outer furnace body 1, a support column 4 is arranged on the cavity bottom of the outer furnace body 1 through a support clamping unit 3, the support clamping unit 3 comprises a support base 31 fixedly connected to the center part of the cavity bottom of the outer furnace body 1, a prismatic shaft 32 is fixedly connected to the upper part of the support base 31, an insertion hole matched with the prismatic shaft 32 is formed in the lower end of the support column 4, a separate smelting mechanism 5 for separately smelting the granular metal and the blocky metal sorted out from the waste batteries is arranged on the outer part of the support column 4, the separate smelting mechanism 5 comprises two separate storage smelting parts 51 arranged on the support column 4 and used for placing the granular metal and the blocky metal sorted out from the waste batteries, the two storage smelting parts 51 are distributed in a staggered manner in the horizontal position, and the heights of the two storage smelting parts 51 in the longitudinal direction are different, and the two storage smelting parts 51 have different vertical height differences, respectively, and a sorting mechanism 6 is arranged on the upper part of the outer furnace body 1 and used for separately feeding the metals with different block diameters in the waste battery recycling into the storage smelting parts 51.

[0033] Please refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In the embodiment, the storage smelting part 51 comprises an arc-shaped ring 511 fixedly connected to the outer part of the support column 4 through a fixing block, a plurality of arc-shaped inner furnace shells 512 slidingly connected to the outer part of the arc-shaped ring 511 and having openings in the upper part and arranged at equal intervals along the arc of the arc-shaped ring 511, and a flipping component 513 arranged between the arc-shaped inner furnace shell 512 and the support column 4 and used for stirring the waste battery metal in the arc-shaped inner furnace shell 512, a top spring 11 is fixedly connected between adjacent two arc-shaped inner furnace shells 512, a limiting ring 12 is fixedly connected to the outer part of the arc-shaped ring 511 in a symmetrical mode, an inclined guide plate 10 is fixedly connected to the upper part of the side wall plate of each of the adjacent two arc-shaped inner furnace shells 512, and the inclined directions of the adjacent two inclined guide plates 10 are opposite.

[0034] Please refer to Figure 1 The sorting mechanism 6 comprises a bearing frame 61 fixedly connected to the upper end face of the outer furnace body 1 through a fixing rod, a rectangular frame 62 fixedly connected to the bearing frame 61 through a connecting spring, a vibrating motor 63 arranged on the rectangular frame 62, a material receiving plate 64 fixedly connected to the rectangular frame 62, screen plates 65 embedded in the material receiving plate 64 in a left-right symmetrical mode, the hole diameter of the screen plate 65 on the left is smaller than that of the screen plate 65 on the right, two guide hoppers 9 are fixedly connected to the lower end face of the bearing frame 61 through connecting rods and located below the screen plates 65 and correspond to the storage smelting parts 51, the guide hoppers 9 are located above the corresponding storage smelting parts 51, the material receiving plate 64 is arranged in an inclined state with the left part being higher than the right part, and a plurality of material blocking strips are fixedly connected to the screen plate 65 on the left at equal intervals.

[0035] The furnace cover 2 is pulled to both sides to open, and then the support 4 is pulled up manually or by external pulling equipment, and then the support 4 drives the sub-melting part 51 to move up, until the two sub-melting parts 51 are completely moved to the upper part of the outer furnace body 1, and then the arc-shaped inner furnace shell 512 is moved around the arc-shaped ring 511 manually or by external equipment, so that each arc-shaped inner furnace shell 512 in the sub-melting part 51 moves close to the arc-shaped inner furnace shell 512 located in the middle, until the arc-shaped inner furnace shells 512 are gathered together, and the gathered arc-shaped inner furnace shells 512 drive the corresponding two inclined guide plates 10 to abut together to form an inverted V shape.

[0036] Then the crushed waste battery metal is poured onto the sieve plate 65 located on the left, and then the vibration motor 63 is controlled to operate to drive the receiving plate 64 to vibrate, and then the receiving plate 64 drives the sieve plate 65 and the rectangular frame 62 to vibrate, and then the sieve plate 65 vibrates the waste battery metal material located on its upper part, and the sieve plate 65 on the left sieves the powder and granular metal during the vibration process, so that the granular and powder metal passes through the inside of the sieve plate 65 and enters the material guide hopper 9 located on the left, and then falls into the arc-shaped inner furnace shell 512 in the sub-melting part 51 located on the left, and the granular and powder metal can smoothly enter the arc-shaped inner furnace shell 512 by abutting together the inclined guide plates 10, and the time length of the waste battery material staying on the left sieve plate 65 is prolonged by the material blocking strip on the left sieve plate 65, so as to ensure that the granular and powder waste battery metal can be completely sieved by the left sieve plate 65.

[0037] The granular and powder waste battery metal that has been sieved rolls to the right to the sieve plate 65 on the right, and then the remaining blocky metal passes through the sieve plate 65 on the right and enters the material guide hopper 9 located on the right, and then enters the arc-shaped inner furnace shell 512 in the sub-melting part 51 located on the right, until the waste battery metal material completely enters the corresponding sub-melting part 51, and then the arc-shaped inner furnace shell 512 that is pressed is released, the top spring 11 resets and drives the arc-shaped inner furnace shell 512 to move along the arc-shaped ring 511, so that the arc-shaped inner furnace shells 512 in the sub-melting part 51 move away from each other, and a gap is formed between the two adjacent arc-shaped inner furnace shells 512, and then the pulled support 4 is sent, so that the support 4 moves downward under the gravity, and then the support 4 drives the sub-melting part 51 to move downward into the outer furnace body 1, and then the two furnace covers 2 are pushed to move close to each other, until the two furnace covers 2 are closed together to seal the inside of the outer furnace body 1.

[0038] The existing smelting furnace is generally in a lower heating mode. The outer furnace body 1 is controlled to operate to heat the lower part, and then the outer furnace body 1 transmits heat to the storage smelting parts 51 located inside. Since the longitudinal height of the storage smelting part 51 on the left is higher than that of the storage smelting part 51 on the right, the storage smelting part 51 on the right is heated by the lower part of the outer furnace body 1 earlier than the storage smelting part 51 on the left, and the storage smelting part 51 on the right is heated more than the storage smelting part 51 on the left. The arc-shaped inner furnace shell 512 is distributed along the arc at equal intervals, so that the waste battery metal is heated from multiple directions, the heating range is increased, and the smelting speed is accelerated, so that the heat can be distributed to the waste battery metal at different heights as needed, avoiding the case that the granular metal is excessively smelted and heated, so that the granular metal and the blocky metal can be synchronously smelted.

[0039] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 In the embodiment, the turning assembly 513 includes a sliding groove 5131 formed on the cavity wall of the arc-shaped inner furnace body, a sliding block 5132 slidingly connected in the sliding groove 5131, two lug groups 5133 fixedly connected to the opposite sides of the corresponding two sliding blocks 5132, a telescopic frame 5134 jointly hinged between the corresponding two lug groups 5133, a turning plate 5135 equidistantly arranged at the lower part of the telescopic frame 5134, a two-way spring telescopic column 5136 jointly hinged to the upper parts of the corresponding two lug groups 5133, a connecting rod 5137 rotationally connected to the outside of the two-way spring telescopic column 5136 through a rotating ring, a circular ring 5138 slidingly connected to the outside of the support column 4, a plurality of arc-shaped blocks 5139 corresponding to the connecting rods 5137 equidistantly slidingly arranged on the outer wall of the circular ring 5138, the arc-shaped blocks 5139 and the upper ends of the corresponding connecting rods 5137 being hinged, a ring-shaped groove 7 formed in the outer wall of the circular ring 5138, the arc-shaped blocks 5139 slidingly connected in the ring-shaped groove 7, and the longitudinal section of the ring-shaped groove 7 being C-shaped.

[0040] Please refer to Figure 3 and Figure 6 A pushing unit 8 for cooperating with the circular ring 5138 is arranged on the furnace cover 2 on the right. The pushing unit 8 includes a sliding rod 81 slidingly connected through the furnace cover 2, two C-shaped clamps 82 fixedly connected to the outer wall of the sliding rod 81 along the axis of the sliding rod 81 for cooperating with the circular ring 5138, and an electric telescopic rod 83 jointly fixedly connected between the upper end of the sliding rod 81 and the upper end surface of the furnace cover 2 through a connecting block.

[0041] The bidirectional spring telescopic column 5136 is in the shortest length in the natural state, so the slider 5132 is in the shortest distance from the support 4 in the initial position, and the synchronous movement of the slide rod 81 will drive the C-shaped clamp 82 to move when the right furnace cover 2 moves left to close, and the C-shaped clamp 82 is sleeved outside the ring 5138 when the two furnace covers 2 are completely closed. Then, the electric telescopic column is powered to drive the slide rod 81 to move up and down reciprocatingly, and the slide rod 81 drives the ring 5138 to move up and down reciprocatingly. When the slide rod 81 and the ring 5138 move downward, the arc block 5139 moves the connecting rod 5137 downward, and the connecting rod 5137 presses the bidirectional spring telescopic column 5136. The bidirectional spring telescopic column 5136 drives the slider 5132 to move away from the support 4 along the sliding groove 5131 through the lug group 5133. The two corresponding sliders 5132 in the arc-shaped inner furnace shell 512 move synchronously and move away from each other, thereby stretching the telescopic frame 5134 and increasing the distance between the push plates 5135.

[0042] When the slider 5132 moves to the farthest distance from the support 4 along the sliding groove 5131, the electric telescopic rod 83 starts to stretch to drive the slide rod 81 to move upward, and the slide rod 81 drives the ring 5138 to move upward through the C-shaped clamp 82. The ring 5138 drives the connecting rod 5137 to move upward through the arc block 5139. The connecting rod 5137 drives the slider 5132 to move toward the support 4 along the sliding groove 5131 through the bidirectional spring telescopic column 5136. The corresponding two sliders 5132 move synchronously and move toward each other, thereby shrinking the telescopic frame 5134 and reducing the distance between the push plates 5135. The push plates 5135 reciprocate toward and away from the support 4 during the melting process to stir the waste battery metal in the arc-shaped inner furnace shell 512, ensuring that the waste battery metal can be uniformly and completely heated.

[0043] When working, the two furnace covers 2 are moved away from each other to open, and then the support 4 is lifted upward to drive the distribution type melting mechanism 5 to move out of the outer furnace body 1. Subsequently, the waste battery metal is poured into the sorting mechanism 6, and the granular metal and the blocky metal are sent into the two storage melting parts 51 after being screened by the sorting mechanism 6. Then, the support 4 is loosened to move downward, and the support 4 drives the storage melting part 51 containing the waste battery metal to move downward into the outer furnace body 1. Then, the two furnace covers 2 are moved toward each other to close, and then the outer furnace body 1 is controlled to heat and melt the waste battery metal. The two storage melting parts 51 with different height distributions are used to heat the granular metal and the blocky metal with different degrees of heating, and the push and shift unit 8 is used to control the push and flip mechanism to stir the waste battery metal in the storage melting part 51, so that the waste battery metal is uniformly heated.
