Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of zinc ore smelting, and in particular relates to a sorting device for zinc ore smelting slag. Background Technology
[0002] Zinc is an important non-ferrous metal, widely used in galvanizing, alloys, batteries, and chemicals. Its production mainly involves extraction from zinc concentrate through pyrometallurgical processes (such as blast furnaces and electric furnaces) or hydrometallurgical processes (such as roasting-leaching-electrolysis). During the smelting process, in addition to obtaining the target metallic zinc, a large amount of solid residue, namely smelting slag, is generated. This slag is a mixture of gangue minerals, unreacted minerals, flux, fuel ash, and some valuable metals that could not be effectively recovered. Zinc smelting slag sorting equipment is a key technological equipment for addressing the dual challenges of resource utilization and environmental governance of solid waste in the zinc smelting industry. It aims to maximize the recovery of valuable metal resources and significantly reduce the environmental risks of tailings through efficient physical sorting of complex slag. It is a crucial link in achieving green and circular zinc smelting processes and improving economic efficiency.
[0003] However, existing sorting devices lack the ability to reduce the impact on the screen. Therefore, after the slag falls onto the top of the screen, it constantly impacts the screen, making it prone to damage. Furthermore, the lack of a drying process allows the slag to adhere to the screen while damp, causing frequent clogging. To address these issues, we provide a zinc ore smelting slag sorting device. Utility Model Content
[0004] The purpose of this utility model is to provide a sorting device for zinc ore smelting slag. The device uses a buffer plate to block the slag, reducing the impact on the screen and ensuring stable slag sorting. At the same time, the combined use of a heating fan and ventilation holes dries the slag inside the sorting box, preventing the slag from being too damp and adhering to the screen.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a sorting device for zinc ore smelting slag, comprising a sorting box; an inclined screen is provided on the inner wall of the sorting box, with the screen being higher on the left and lower on the right; a second drop pipe connected to the interior is fixed to the lower end face of the sorting box located at the right end of the screen; a sliding block is fixed to the bottom surface inside the sorting box, with the sliding block being lower on the left and higher on the right; a first drop pipe connected to the interior is fixed to the lower end face of the sorting box located at the left end of the sliding block; a cover plate is bolted to the upper end face of the sorting box; a feed pipe connected to the interior of the sorting box is fixed to the upper end face of the cover plate near the left end of the screen; a buffer plate is provided inside the feed pipe; a heating fan connected to the interior of the sorting box is fixed to the left side wall of the sorting box; a ventilation hole is provided on the right side wall of the sorting box; and an inclined block is fixed inside the sorting box located to the right of the second drop pipe.
[0007] The present invention is further configured such that the front and rear side walls of the screen are fixed with abutment strips that connect with the inner wall of the sorting box, and the front and rear side walls of the sorting box located at both ends of the abutment strips are provided with adjustment ports, and the upper end face of the abutment strips is fixed with adjustment blocks located in the adjustment ports.
[0008] The present invention is further configured such that an adjustable block end face passing through the adjustment port is fixed with a movable plate connected to the outer wall of the sorting box, and multiple sets of square plates, each flush with the lower end face of the adjustment port, are fixed on the front and rear sides of the outside of the sorting box.
[0009] The present invention is further configured such that a positioning hole is provided through the upper end face of the square plate, and a positioning rod is fixed through the positioning hole on the lower end face of the movable plate. A linkage spring is sleeved on the positioning rod located between the square plate and the movable plate.
[0010] The present invention is further configured such that a positioning block is fixed on the right side wall outside the feed pipe, and the upper end face of the positioning block is provided with two sets of arc holes that communicate with the inside of the feed pipe.
[0011] The present invention is further provided with a locking plate bolted to the right side wall of the feed pipe at the position below the buffer plate, and a shaft rotatably connected to the feed pipe is fixed to the front and rear side walls of the buffer plate near the locking plate.
[0012] The present invention is further configured such that two arc-shaped rods are fixed on the lower end face of the buffer plate, passing through the through hole of the locking plate and slidably disposed inside the arc hole, and an arc-shaped spring is sleeved on each arc-shaped rod located between the buffer plate and the locking plate.
[0013] This utility model has the following beneficial effects:
[0014] 1. After the slag falls into the feed pipe, the slag will first come into contact with the upper surface of the buffer plate. When the buffer plate is impacted by the slag, it will rotate inside the feed pipe to dissipate the impact of the slag. The buffer plate blocks the slag, reduces the impact on the screen, and ensures that the screen can stably sort the slag.
[0015] 2. Control the operation of the heating fan. The hot air generated by the heating fan will be blown into the sorting box. At the same time, the hot air in the sorting box will flow out from the ventilation holes, so that the air inside the sorting box can circulate with each other. The heat will dry the slag in the sorting box, prevent the slag from adhering to the surface of the screen, and ensure that the slag can be stably sorted on the screen. Attached Figure Description

Detailed Implementation
[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] Please see Figures 1 to 5 This utility model is a sorting device for zinc ore smelting slag. The buffer plate 4 blocks the slag, reduces the impact on the screen 5, and ensures that the screen 5 can stably sort the slag. At the same time, the heating fan 104 and the ventilation hole 103 work together to dry the slag inside the sorting box 1, so as to prevent the slag from being too damp and adhering to the screen 5.
[0026] Specifically, the sorting box 1 has an inclined screen 5 on its inner wall, with the screen 5 positioned higher on the left and lower on the right. A drop pipe 102, connected to the interior of the sorting box 1, is fixed to the lower end of the sorting box 1 at the right end of the screen 5. A sliding block 6, aligned with the vertical position of the screen 5, is fixed to the bottom of the sorting box 1, with the sliding block 6 positioned lower on the left and higher on the right. A drop pipe, connected to the interior of the sorting box 1, is fixed to the lower end of the sorting box 1 at the left end of the sliding block 6. 101. A cover plate 2 is bolted to the upper end of the sorting box 1. A feed pipe 3 connected to the inside of the sorting box 1 is fixed to the upper end of the cover plate 2 near the left end of the screen 5. A buffer plate 4 is installed inside the feed pipe 3. A heating fan 104 connected to the inside of the sorting box 1 is fixed to the left side wall of the outside of the sorting box 1. A ventilation hole 103 is opened on the right side wall of the sorting box 1. An inclined block 105 is fixed inside the sorting box 1 located to the right of the drop pipe 102.
[0027] The operation process of this embodiment is as follows: With the above structure, the slag produced in zinc ore smelting is poured into the feed pipe 3, and the slag will fall directly onto the upper end of the buffer plate 4. After being impacted by the slag, the buffer plate 4 tilts, and the slag will slide from the gap between the buffer plate 4 and the feed pipe 3 onto the screen 5. At this time, the slag is screened by the screen 5, and the large slag particles will slide directly onto the screen 5 and be discharged from the drop pipe 102. The screened slag will fall onto the upper end of the sliding block 6, and the slag will slide onto the drop pipe 101 from the upper end of the sliding block 6, thereby directly discharging the slag from the inside of the drop pipe.
[0028] Meanwhile, when the slag is being screened, the heating fan 104 can be controlled to work. The hot air generated by the heating fan 104 will be blown into the sorting box 1, and the hot air in the sorting box 1 will flow out from the ventilation hole 103. This allows the air inside the sorting box 1 to circulate, and the heat dries the slag in the sorting box 1, preventing the slag from adhering to the surface of the screen 5 and ensuring that the slag can be stably sorted on the screen 5.
[0029] When the slag falls into the feed pipe 3, it will first come into contact with the upper surface of the buffer plate 4. When the buffer plate 4 is impacted by the slag, it will rotate inside the feed pipe 3 to relieve the impact of the slag. Example 2
[0030] Please see Figure 2 , Figure 3 and Figure 4 Based on Example 1, the movable plate 502 and the linkage spring 504 are used in combination to enable the screen 5 to move up and down stably after being hit by slag, thus ensuring stable sorting work.
[0031] Specifically, the front and rear side walls of the screen 5 are fixed with abutment strips 505 that connect with the inner wall of the sorting box 1. Adjustment ports 106 are opened through the front and rear side walls of the sorting box 1 located at both ends of the abutment strips 505. Adjustment blocks 501 are fixed in the adjustment ports 106 at the upper end face of the abutment strips 505. Movable plates 502 that connect with the outer wall of the sorting box 1 are fixed at the end face of the adjustment blocks 501 that pass through the adjustment ports 106. Multiple sets of square plates 107 that are flush with the lower end face of the adjustment ports 106 are fixed on the front and rear sides of the outside of the sorting box 1. Positioning holes 108 are opened through the upper end face of the square plates 107. Positioning rods 503 that pass through the positioning holes 108 are fixed at the lower end face of the movable plates 502. Linkage springs 504 are sleeved on the positioning rods 503 located between the square plates 107 and the movable plates 502.
[0032] The operation process of this embodiment is as follows: After the slag falls to the upper position of the screen 5 through the above structure, the screen 5 will shake up and down, thereby the screen 5 will screen the slag. The screen 5 will drive the adjusting block 501 to slide in the adjusting port 106, and the adjusting block 501 will drive the movable plate 502 to compress the linkage spring 504 or push the movable plate 502 through the linkage spring 504, so that the screen 5 will return to the upward position, thereby controlling the screen 5 to move up and down in the sorting box 1, thereby shaking off the slag on the screen 5, so that some of the slag falls onto the sliding block 6, and the other part of the slag continues to slide down along the surface of the screen 5. Example 3
[0033] Please see Figure 2and Figure 5 Based on Example 1, the arc-shaped rod 403 limits the arc-shaped spring 404 to ensure the stability of the arc-shaped spring 404 when compressed.
[0034] Specifically, a positioning block 301 is fixed on the right side wall outside the feed pipe 3. The upper end face of the positioning block 301 is provided with two sets of arc holes 302 that communicate with the inside of the feed pipe 3. A locking plate 401 that is bolted to the right side wall inside the feed pipe 3 is provided below the buffer plate 4. The front and rear side walls of the buffer plate 4 are fixed with shafts 402 that are rotatably connected to the feed pipe 3 near the locking plate 401. Two arc-shaped rods 403 that pass through the through holes of the locking plate 401 and slide inside the arc holes 302 are fixed on the lower end face of the buffer plate 4. Each arc-shaped rod 403 located between the buffer plate 4 and the locking plate 401 is fitted with an arc-shaped spring 404.
[0035] The operation process of this embodiment is as follows: When the buffer plate 4 tilts, the buffer plate 4 will drive the arc rod 403 to slide in the arc hole 302, and the buffer plate 4 will compress the arc spring 404. The arc spring 404 will push the buffer plate 4 to rotate upward, so that the buffer plate 4 can rotate autonomously. Thus, the buffer plate 4 can always play a buffering role. At the same time, the arc rod 403 slides inside the arc hole 302, so the arc rod 403 limits the arc spring 404 and ensures the stability of the arc spring 404 under compression.
