[0001] The utility model belongs to the technical field of solid waste crushing, and particularly relates to a zinc-containing solid waste crushing device. Background Art

[0002] During the preparation of zinc oxide, solid waste will be generated. These wastes are mainly composed of raw materials that are not completely converted, impurities, and by-products generated during the zinc oxide smelting process. They may contain a certain amount of zinc oxide, zinc oxides, other metal oxides, and non-metallic substances. The crushing of solid waste generated during the zinc oxide preparation process is an important treatment step, mainly aiming to homogenize the waste and reduce its volume for subsequent resource recovery or harmless treatment. However, the crushing devices in the prior art are not thorough enough for crushing zinc-containing solid waste, resulting in low recovery utilization rate. Moreover, during the feeding process, the solid waste is put into the inner cavity of the device body at one time without buffering, which may cause the feeding port to be blocked due to excessive one-time feeding of solid waste, affecting the crushing efficiency. Therefore, this application proposes a zinc-containing solid waste crushing device. Summary of the Utility Model

[0003] This application proposes a zinc-containing solid waste crushing device. By setting a series of structures, it solves the problem that the crushing of solid waste generated during the zinc oxide preparation process is an important treatment step, mainly aiming to homogenize the waste and reduce its volume for subsequent resource recovery or harmless treatment. However, the crushing devices in the prior art are not thorough enough for crushing zinc-containing solid waste, resulting in low recovery utilization rate. Moreover, during the feeding process, the solid waste is put into the inner cavity of the device body at one time without buffering, which may cause the feeding port to be blocked due to excessive one-time feeding of solid waste, affecting the crushing efficiency.

[0004] This application proposes a zinc-containing solid waste crushing device, including a device body. A feed hopper is connected to the center of the top of the device body. Two buffer feeding mechanisms are symmetrically arranged on the outer side of the feed hopper. The other ends of the two buffer feeding mechanisms extend through the top of the device body into the inner cavity of the device body. A first crushing mechanism is arranged in the inner cavity of the device body, and the first crushing mechanism is located directly below the buffer feeding mechanism. Two second crushing mechanisms are symmetrically arranged below the first crushing mechanism, and the two second crushing mechanisms are fixed on the inner side wall of the device body. A collection box is installed at the bottom of the inner cavity of the device body, and the collection box is communicated with the two second crushing mechanisms;

[0005] The first crushing mechanism includes a mutually cooperating first crushing wheel and a second crushing wheel. The first crushing wheel and the second crushing wheel are installed in the inner cavity of the device body through a first rotating shaft. It also includes a first motor fixedly installed on the outer side of the device body. The first motor is connected to the first rotating shaft through a coupling. The first crushing wheel and the second crushing wheel are a pair of meshing gears. Two first feeding channels are symmetrically arranged below the first crushing wheel and the second crushing wheel. The two first feeding channels are interconnected and their two ends are respectively connected to the tops of the two second crushing mechanisms.

[0006] Furthermore, the second crushing mechanism includes a crushing box fixed to the side of the inner cavity of the device body. A second motor is installed on the outer side of the top of the crushing box. The output end of the second motor extends through the top of the crushing box into the inner cavity of the crushing box and is connected to a second rotating shaft. The other end of the second rotating shaft is connected to a crushing disc. A number of crushing heads are evenly arranged on the outer surface of the crushing disc. The side walls of the inner cavity of the crushing box are symmetrically connected with crushing hoppers matching the crushing disc. The crushing disc is located in the inner cavity of the crushing hoppers. A feeding port is formed between the two crushing hoppers. The feeding port is communicated with a second feeding channel. The other ends of the two second feeding channels are jointly communicated with a collection box.

[0007] Furthermore, the buffer feeding mechanism includes two fixed blocks symmetrically fixed to the outside of the feeding hopper, a fixed pulley located on one side of the fixed block. The fixed pulley is fixedly installed on the top of the device body. A sliding groove is formed in the inner cavity of the fixed block. A sliding plate is slidably installed on the sliding groove. A compression spring and a dragging rope are fixed to the side of the sliding plate away from the feeding hopper. The compression spring is located in the inner cavity of the fixed block. The other end of the dragging rope extends to the outside of the fixed block and is wound around the fixed pulley. It also includes a positioning block. The positioning block is fixedly installed on the outer side of the top of the device body and is located on the other side of the fixed pulley. A buffer feeding plate is hinged to the side of the positioning block close to the fixed pulley. The other end of the buffer feeding plate inclines downward and extends through a through groove formed in the top of the device body into the inner cavity of the device body. The end of the other end of the dragging rope is fixed to the buffer feeding plate.

[0008] Furthermore, the two first feeding channels incline downward from the middle to both sides.

[0009] Furthermore, a feeding solenoid valve is installed on the second feeding channel.

[0010] As can be seen from the above technical solutions, during use, the solid waste is fed into the device through the feed hopper. The buffer feeding mechanism arranged on both sides of the feed hopper buffers the solid waste fed into the inner cavity of the device, enabling it to be fed slowly and avoiding blockage caused by excessive feeding at one time. At this time, the first motor is started, and the first motor drives the first rotating shaft to rotate, thereby driving the first crushing wheel to rotate. Since the first crushing wheel and the second crushing wheel are a pair of meshing gears, when the first crushing wheel rotates, the second crushing wheel also rotates simultaneously, thoroughly crushing the passing solid waste for the first time. The crushed waste will fall onto the two symmetrically arranged first discharge channels below it and be fed into the two second crushing mechanisms through the two first discharge channels for secondary crushing. The waste after secondary crushing is fed into the inner cavity of the connected collection box for collection, solving the problem that the crushing device in the prior art is not thorough enough for the crushing of zinc-containing solid waste, resulting in low recycling rate, and during the feeding process, the solid waste is fed into the inner cavity of the device at one time without buffering, causing the feeding port to be blocked due to excessive feeding at one time and affecting the crushing efficiency.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By setting a series of structures in this application, the solid waste is crushed more thoroughly, improving the recycling rate. Specifically, the solid waste is fed into the device through the feed hopper, and the buffer feeding mechanism buffers the solid waste to enable it to be fed slowly, avoiding blockage caused by excessive feeding at one time. The first motor is started, and the first motor drives the first rotating shaft to rotate, thereby driving the first crushing wheel to rotate. Since the first crushing wheel and the second crushing wheel are a pair of meshing gears, when the first crushing wheel rotates, the second crushing wheel also rotates simultaneously, thoroughly crushing the passing solid waste for the first time. The crushed waste falls onto the two first discharge channels, and is fed into the second crushing mechanism through the two first discharge channels for secondary crushing. The waste after secondary crushing is fed into the inner cavity of the connected collection box for collection, solving the problem that the crushing device in the prior art is not thorough enough for the crushing of zinc-containing solid waste, resulting in low recycling rate, and during the feeding process, the solid waste is fed into the inner cavity of the device at one time without buffering, causing the feeding port to be blocked due to excessive feeding at one time and affecting the crushing efficiency.

[0018] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings.

[0019] See Figure 1 - Figure 2 .

[0020] The crushing of solid waste generated during the zinc oxide preparation process is an important treatment step, mainly aiming to homogenize the waste and reduce its volume to facilitate subsequent resource recovery or harmless treatment. However, the crushing devices in the prior art are not thorough enough for the crushing of zinc-containing solid waste, resulting in low recovery utilization rate. Moreover, during the feeding process, the solid waste is directly fed into the inner cavity of the device body 1 at one time without buffering, which may cause the feeding port to be blocked due to excessive one-time feeding of the solid waste, affecting the crushing efficiency. Therefore, this application proposes a zinc-containing solid waste crushing device, which includes a device body 1. The center of the top of the device body 1 is connected to a feeding hopper 2. Two buffer feeding mechanisms are symmetrically arranged on the outside of the feeding hopper 2. The other ends of the two buffer feeding mechanisms extend through the top of the device body 1 into the inner cavity of the device body 1. A first crushing mechanism is arranged in the inner cavity of the device body 1, and the first crushing mechanism is located directly below the buffer feeding mechanism. Two second crushing mechanisms are symmetrically arranged below the first crushing mechanism, and the two second crushing mechanisms are fixed on the inner side wall of the device body 1. A collection box 3 is installed at the bottom of the inner cavity of the device body 1, and the collection box 3 is connected to the two second crushing mechanisms;

[0021] The first crushing mechanism includes a first crushing wheel 4 and a second crushing wheel 5 that cooperate with each other. The first crushing wheel 4 and the second crushing wheel 5 are installed in the inner cavity of the device body 1 through a first rotating shaft 6. It also includes a first motor 7 fixedly installed outside the device body 1. The first motor 7 is connected to the first rotating shaft 6 through a coupling. The first crushing wheel 4 and the second crushing wheel 5 are a pair of meshing gears. Two first feeding channels 8 are symmetrically arranged below the first crushing wheel 4 and the second crushing wheel 5. The two first feeding channels 8 are interconnected and the two ends are respectively connected to the tops of the two second crushing mechanisms. Specifically, the solid waste is fed into the device through the feeding hopper 2. The buffer feeding mechanism arranged on both sides of the feeding hopper 2 buffers the solid waste fed into the inner cavity of the device body 1, making it feed slowly and avoiding blockage caused by excessive feeding at one time. At this time, the first motor 7 is started. The first motor 7 drives the first rotating shaft 6 to rotate, thereby driving the first crushing wheel 4 to rotate. Since the first crushing wheel 4 and the second crushing wheel 5 are a pair of meshing gears, when the first crushing wheel 4 rotates, the second crushing wheel 5 also rotates simultaneously, performing the first thorough crushing on the passing solid waste. The crushed waste will fall onto the two first feeding channels 8 symmetrically arranged below it and be fed into the two second crushing mechanisms respectively through the two first feeding channels 8 for the second crushing. The waste after the second crushing is fed into the inner cavity of the collection box 3 connected to it for collection.

[0022] Further, the second crushing mechanism includes a crushing box 9 fixed to the side of the inner cavity of the device body 1. A second motor 10 is installed outside the top of the crushing box 9. The output end of the second motor 10 extends through the top of the crushing box 9 into the inner cavity of the crushing box 9 and is connected to a second rotating shaft 11. The other end of the second rotating shaft 11 is connected to a crushing disc 12. A number of crushing heads 13 are evenly arranged on the outer surface of the crushing disc 12. The side walls of the inner cavity of the crushing box 9 are symmetrically connected with crushing hoppers 14 that match the crushing disc 12. The crushing disc 12 is located in the inner cavity of the crushing hoppers 14. A feeding port 15 is formed between the two crushing hoppers 14. The feeding port 15 is connected to a second feeding channel 16. The other ends of the two second feeding channels 16 are commonly connected to the collection box 3. Specifically, the waste after the first crushing is fed into the inner cavity of the crushing box 9. By starting the second motor 10, the second motor 10 drives the second rotating shaft 11 to rotate, and at the same time drives the crushing disc 12 to rotate. The number of crushing heads 13 evenly arranged on the outer surface of the crushing disc 12 can perform the second crushing on the fed waste. The crushed waste is discharged through the feeding port 15 formed between the two crushing hoppers 14 and finally fed into the collection box 3 through the second feeding channel 16. It should be noted here that the other ends of the two first feeding channels 8 extend into the inner cavity of the crushing box 9 and are located directly above the cavity formed between the crushing disc 12 and the crushing hoppers 14, enabling the waste to be accurately fed and crushed.

[0023] Furthermore, the buffer feeding mechanism includes two fixed blocks 17 symmetrically fixed on the outer side of the feeding hopper 2, a fixed pulley 18 located on one side of the fixed block 17. The fixed pulley 18 is fixedly installed on the top of the device body 1. A chute 19 is provided in the inner cavity of the fixed block 17. A sliding plate 20 is slidably installed on the chute 19. A compression spring 21 and a drag rope 22 are fixed on the side of the sliding plate 20 away from the feeding hopper 2. The compression spring 21 is located in the inner cavity of the fixed block 17. The other end of the drag rope 22 extends to the outside of the fixed block 17 and is wound around the fixed pulley 18. It also includes a positioning block 23. The positioning block 23 is fixedly installed on the outer side of the top of the device body 1 and is located on the other side of the fixed pulley 18. A buffer feeding plate 24 is hinged on the side of the positioning block 23 close to the fixed pulley 18. The other end of the buffer feeding plate 24 is inclined downward and extends into the inner cavity of the device body 1 through a through groove provided on the top of the device body 1. The end of the other end of the drag rope 22 is fixed on the buffer feeding plate 24. Specifically, when the solid waste enters the inner cavity of the device body 1 from the feeding hopper 2, it will first fall on the buffer feeding plate 24. At this time, since the other end of the buffer feeding plate 24 is hinged to the positioning block 23, the inclination of the buffer feeding plate 24 can be realized. The buffer feeding plate 24 will incline at a certain angle due to the self-weight of the solid waste. At the same time, when the buffer feeding plate 24 inclines downward, it will drive the cooperation of the drag rope 22 and the fixed pulley 18 to slide the sliding plate 20 on the chute 19, generating a certain displacement. When there is no solid waste on the buffer feeding plate 24, the buffer feeding plate 24 will reset due to the nature of the compression spring 21 itself, and at the same time drive the buffer feeding plate 24 to return to the initial position, which can further buffer the feeding of the solid waste and avoid blockage caused by excessive feeding at one time, ultimately affecting the crushing efficiency of the solid waste.

[0024] Furthermore, the two first feeding channels 8 are inclined downward from the middle to both sides. Specifically, the two first feeding channels 8 are inclined to enable the solid waste to easily enter the crushing box 9 along the inclined first feeding channels 8 for the second crushing work.

[0025] Furthermore, a feeding solenoid valve 25 is installed on the second feeding channel 16. Specifically, by setting the feeding solenoid valve 25, the discharge of the solid waste can be controlled at any time, improving the practicability of the device.

[0026] As can be seen from the above technical solutions, during use, solid waste is introduced through the feed hopper 2. The buffer feeding mechanism arranged on both sides of the feed hopper 2 buffers the solid waste introduced into the inner cavity of the device body 1. Specifically, when the solid waste is introduced from the feed hopper 2 into the inner cavity of the device body 1, it will first fall on the buffer feeding plate 24. At this time, since the other end of the buffer feeding plate 24 is hinged to the positioning block 23, the inclination of the buffer feeding plate 24 can be realized. The buffer feeding plate 24 will tilt downward by a certain angle due to the self-weight of the solid waste. At the same time, when the buffer feeding plate 24 tilts downward, it will drive the cooperation of the dragging rope 22 and the fixed pulley 18 to slide the sliding plate 20 on the sliding groove 19, generating a certain displacement. When there is no solid waste on the buffer feeding plate 24, the buffer feeding plate 24 will reset due to the nature of the compression spring 21, and at the same time drive the buffer feeding plate 24 back to the initial position, which can further buffer the feeding of the solid waste, avoid blockage caused by excessive feeding at one time, and ultimately affect the crushing efficiency of the solid waste. Start the first motor 7, the first motor 7 drives the first rotating shaft 6 to rotate, thereby driving the first crushing wheel 4 to rotate. Since the first crushing wheel 4 and the second crushing wheel 5 are a pair of meshing gears, when the first crushing wheel 4 rotates, the second crushing wheel 5 also rotates at the same time to thoroughly crush the passing solid waste for the first time;

[0027] The crushed waste will fall onto two symmetrically arranged first feeding channels 8 below it, and are respectively introduced into two second crushing mechanisms through the two first feeding channels 8 for secondary crushing. The two first feeding channels 8 are arranged obliquely so that the solid waste can easily enter the crushing box 9 along the inclined first feeding channels 8 for the secondary crushing work. Specifically, the waste after the first crushing is introduced into the inner cavity of the crushing box 9. By starting the second motor 10, the second motor 10 drives the second rotating shaft 11 to rotate, and at the same time drives the crushing disc 12 to rotate. A number of uniformly arranged crushing heads 13 on the outer surface of the crushing disc 12 can perform secondary crushing on the introduced waste. The crushed waste is then discharged through the feeding port 15 formed between the two crushing hoppers 14, and finally enters the collection box 3 through the second feeding channel 16. It should be noted here that the other ends of the two first feeding channels 8 extend into the inner cavity of the crushing box 9 and are directly above the cavity formed between the crushing disc 12 and the crushing hoppers 14, which can realize the accurate introduction and crushing of the waste. The waste after the secondary crushing is introduced into the inner cavity of the connected collection box 3 for collection, which solves the problem that the crushing of solid waste generated during the preparation of zinc oxide is an important treatment step. Its main purpose is to homogenize the waste and reduce its volume for subsequent resource recovery or harmless treatment. However, the crushing devices in the prior art are not thorough enough in crushing zinc-containing solid waste, resulting in low recycling rate. Moreover, during the feeding process, the solid waste is put into the inner cavity of the device body 1 at one time without buffering, resulting in blockage of the feeding port due to excessive feeding at one time and affecting the crushing efficiency.
