Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a tailings recycling, crushing and grinding equipment. Background Technology

[0002] The rise of the recycled lead industry has undeniable positive significance. On the one hand, it enables the recycling of lead resources, effectively reducing primary lead mining; on the other hand, it standardizes the treatment of waste lead-acid batteries, greatly reducing environmental pollution. Furthermore, recycled lead production boasts economic advantages such as low energy consumption, low cost, and high profitability, which has also spurred the vigorous development of related industries like waste battery recycling, creating numerous job opportunities.

[0003] However, significant problems remain in the current production of recycled lead. Each batch of recycled lead generates a large amount of smelting slag, which is classified as hazardous waste, containing up to 42% iron and 6.5% lead. Typically, most of this slag is simply piled up in warehouses or outsourced for disposal. However, piling up slag not only occupies a lot of space but also poses a risk of leakage, potentially polluting soil and groundwater. Outsourcing only temporarily transfers the risk and doesn't fundamentally solve the problem; all these practices pose significant potential environmental risks. If the slag could be processed through secondary crushing, grinding, and gravity separation to extract the lead, the remaining powdery material could be sold to cement producers as iron powder, which would be both environmentally friendly and maximize profits. Commonly used grinding equipment is the ball mill. Existing ball mills typically have a side-opening feed inlet, resulting in a generally large size. After grinding, it's inconvenient to completely discharge the internal material and change materials.

[0004] Therefore, there is an urgent need for a small ball mill to grind the waste slag from recycled lead smelting, to pre-treat the lead to be recovered, and to facilitate the complete discharge of the ground material. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] This utility model provides a tailings recycling, crushing, and grinding equipment, designed to crush and grind recycled lead smelting waste slag while facilitating complete material discharge. Figures 1-6 As shown, the device includes a support frame 1, which supports the ball mill barrel 3 and the transmission components to ensure stable operation of the device during operation; the ball mill barrel 3 is a material grinding container rotatably mounted on the support frame 1; a drive device 2 drives the ball mill barrel 3 to rotate, providing a continuous and stable power source to ensure that the ball mill barrel 3 operates at a predetermined speed; metal balls are placed inside the ball mill barrel 3, and the metal balls form a throwing motion during rotation, repeatedly impacting and rubbing the material, thereby effectively breaking down the particle structure; steel liners are evenly installed inside the barrel body 31, which protect the inner wall of the barrel from wear and increase the friction between the material and the metal balls, improving grinding efficiency; the ball mill barrel 3 includes a barrel body 31 and a sealing plate 32. The barrel body 31 serves as the main cavity for containing and grinding materials, and the sealing plate 32 facilitates sealing the grinding space to prevent material leakage; a material exchange port 311 is provided on the barrel body 31, which facilitates the input and output of materials and improves the efficiency of material replacement; the sealing plate 32 is hinged to the barrel body 31, and the hinged structure facilitates sealing. The closing plate 32 can be opened quickly, improving the convenience of equipment maintenance and use. Locking hooks 323 are provided on both sides of the tail end of the closing plate 32, and corresponding latches 313 are provided on both sides of the ball mill barrel 3. The latches 313 and the locking hooks 323 work together to achieve a stable closure of the closing plate 32, ensuring the sealing and safety of the grinding process. The closing plate 32 includes a plate body 321 and a crash barrier 324. The overall size of the plate body 321 is larger than that of the material exchange port 311, and the size of the crash barrier 324 is... The material exchange port 311 is properly embedded, and the anti-collision plate 324 enhances the impact resistance of the sealed part to prevent damage to the plate 321 caused by the impact of the internal metal ball. The plate 321 is the same width as the barrel body 31 to ensure that the sealing plate 32 fits tightly with the barrel body 31 and prevent dust or material from spilling out. The curvature of the plate 321 is the same as that of the barrel body 31, so that the sealing structure fits naturally with the barrel body 31 and improves the sealing effect. The anti-collision plate 324 is fixedly installed in the middle of the plate 321, and the locking hooks 323 are installed on both sides of the tail of the plate 321.

[0028] like Figure 2 As shown, the support frame 1 includes a frame body 101, a rotating shaft 102, and a fixed plate 103. The frame body 101 serves as the main load-bearing structure, providing stable support for the entire equipment. There are two rotating shafts 102, which are rotatably mounted on both sides of the frame body 101, allowing the ball mill barrel 3 to rotate uniformly on the horizontal axis. The fixed plate 103 is installed inside the rotating shafts 102 and is used to connect the barrel body 31 to the rotating shafts 102, realizing the effective transmission of power. The barrel body 31 is fixedly installed between the fixed plates 103 of the two rotating shafts 102. A mounting base 104 is provided on one side of the frame body 101 for fixing. The motor 201 and related drive components form a complete transmission system. The drive device 2 includes a motor 201, a first gear 202, and a second gear 203. The motor 201 serves as a power source, driving the first gear 202 to rotate, thereby driving the ball mill barrel 3 to rotate through gear meshing. The motor 201 is fixedly mounted on the mounting base 104. The second gear 203 is fixedly connected to the outside of the rotating shaft 102 near the base. The first gear 202 is fixedly connected to the output shaft of the motor 201 and meshes with the second gear 203. The gear meshing structure can smoothly transmit the rotation of the motor 201 to the ball mill barrel 3, improving operating accuracy and working efficiency.

[0029] The closing plate 32 is opened and closed via a hinge shaft. The use of the hinge shaft allows the closing plate 32 to be rotated open, facilitating the feeding or discharging of materials by the operator. During grinding, the material is placed into the barrel 31 through the material exchange port 311. This operation is simple and quick, effectively saving preparation time and improving equipment efficiency. When the closing plate 32 is closed, the locking buckle 313 and the locking hook 323 fix the closing plate 32 to achieve sealed grinding and prevent material or dust from scattering and causing environmental pollution. The drive device 2 drives the ball mill barrel 3 to rotate. The rotation of the barrel causes the internal metal balls to collide and shear with the material multiple times, thereby achieving the purpose of grinding and crushing. The internal metal balls are driven and fall from a height to collide with the material, thereby grinding and crushing the material.

[0030] In a preferred embodiment, to facilitate material discharge and prevent metal balls from being discharged with the material, the barrel body 31 also includes a strainer 33. This structure enables material screening and discharge without compromising the seal, preventing metal balls from mixing into the finished product. Figure 5 As shown, mounting grooves 322 are provided on both sides of the plate 321, such as... Figure 4 As shown, circumferential slide rails 312 are provided on both sides of the barrel body 31. The slide rails 312 are used to guide the sliding path of the material leakage plate 33. When the mounting plate 332 is in the closed state, the slide rails 312 and the mounting grooves 322 are engaged with each other, and the engagement structure provides sliding limit. The material leakage plate 33 is limited to sliding on the slide rails 312. Figure 6As shown, the material leakage plate 33 includes a crossbeam 331, a mounting plate 332, and sliding rods 333. The crossbeam 331 provides support and separation, allowing material to fall through the gaps while the metal ball is intercepted and retained inside the barrel. The mounting plate 332 has the same curvature as the barrel body 31, and there are two mounting plates 332. Multiple crossbeams 331 are fixed between the two mounting plates 332. Four sliding rods 333 are symmetrically fixed on both sides of the two mounting plates 332. The sliding rods 333 pass through the slide rail 312, forming a guide structure through an interlocking design, enabling... Controlled sliding; wherein, the length of the slide rail 312 is more than twice the length of the mounting plate 332, so that the material discharge plate 33 has sufficient sliding stroke; when the closing plate 32 is closed, the material discharge plate 33 cannot move due to the blocking position of the closing plate 32 and the slide rail 312, preventing the material discharge plate 33 from accidentally sliding during the discharge process; when the closing plate 32 is opened, the material discharge plate 33 can slide along the slide rail 312 to the material exchange port 311, which facilitates the smooth discharge of the ground material, and the ground material falls along the gap between the crossbeams 331; The metal balls remain inside the barrel 31 to prevent them from being mixed with the material. The material discharge plate 33 also includes a roller 334, which is rotatably mounted on the outside of the slide bar 333. The roller 334 reduces sliding resistance and improves smoothness of sliding. The roller 334 rolls against the barrel body, effectively reducing friction between the slide rail 312 and the barrel body. The material discharge plate 33 also includes a threaded locking rod 335 and a nut 336 for fixing it. One end of the threaded locking rod 335 is provided with a handle, which facilitates manual operation and improves the convenience of adjustment. The diameter of the handle is larger than the slide groove; the threaded part of the threaded locking rod 335 passes through the slide rail 312 and is movably installed on the side of the mounting plate 332 away from the closing plate 32. This installation position is far away from the cover area to avoid operational interference; the nut 336 is installed inside the threaded locking rod 335 and is used to tighten and control the sliding state; the diameter of the nut 336 is larger than the slide groove to prevent it from going out completely and causing loosening; the material leakage plate 33 can be fixed or loosened by turning the nut 336, which is simple and quick to adjust and ensures safe operation.

[0031] During operation, the pre-treated recycled lead smelting waste is first fed into the ball mill 3 through the material exchange port 311. Then, the sealing plate 32 is closed and locked in place by the locking hook 323 and the locking buckle 313 to ensure a sealed barrel. After starting the motor 201, the motor drives the first gear 202 to rotate, which meshes with the second gear 203, causing the connected rotating shaft 102 and the ball mill 3 to rotate synchronously. During the rotation of the ball mill 3, the metal balls inside are lifted and fall freely, continuously impacting and rubbing against the waste, thus achieving material crushing and grinding. After grinding, the sealing plate 32 is opened. At this time, the material leakage plate 33 slides along the slide rail 312 to the material exchange port 311 under gravity or manual force. The powdery material falls through the gap in the crossbeam 331 for recycling, while the metal balls, due to their large size, cannot pass through the gap and remain inside the barrel. The rollers 334 and threaded locking rods 335 on the material discharge plate 33 ensure smooth sliding and can be locked as needed, facilitating material discharge and replacement for the next grinding.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
