Description

Technical Field

[0001] The invention relates to the technical field of waste cathode carbon block pretreatment, in particular to a waste cathode carbon block pretreatment crushing and grinding device. Background Art

[0002] Waste cathode carbon blocks refer to eliminated or expired cathode carbon blocks. They are an important component of aluminum electrolytic cells and are usually used as cathodes of aluminum electrolytic cells. Waste cathode carbon blocks may contain a large amount of soluble fluoride and cyanide. These harmful substances will transfer and volatilize into the atmosphere after long-term wind, sun and rain, or mix into rivers and seep into the ground with rainwater, causing pollution to the soil and groundwater. Therefore, it is necessary to recycle the waste cathode carbon blocks. Before recycling and reuse, waste cathode carbon blocks usually need to undergo a series of pretreatments, including classification and collection, crushing and screening, and separation of valuable components. In the process of pre-processing the waste cathode carbon blocks, the staff puts the waste cathode carbon blocks on the conveyor belt and uses the conveyor belt to feed the jaw crusher. The jaw crusher crushes the waste cathode carbon blocks, and the crushed waste cathode carbon blocks enter the ball mill for grinding. However, in the actual processing process, the recycled waste cathode carbon blocks will inevitably have different sizes. This is mainly due to various factors in the production process, use conditions or recycling process. As a result, there are often large-sized waste cathode carbon blocks that enter the jaw crusher for crushing. Due to their large size, waste cathode carbon blocks may not be evenly stressed during crushing, resulting in uneven particle size distribution after crushing. Some parts may be too finely crushed, while other parts remain in large blocks. As a result, in the subsequent grinding process, large particles require more time and energy to be ground to the required particle size, while small particles may reach the fineness requirements too early and be over-ground, or even form an "over-crushing" phenomenon, which not only reduces the production efficiency of the mill, but also increases energy consumption and wear. For this reason, we propose a waste cathode carbon block pretreatment crushing and grinding device. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-13 The present invention provides a technical solution: a waste cathode carbon block pretreatment crushing and grinding device. The present invention makes corresponding improvements to the technical problems in the background technology, including a crushing mechanism 1, a belt conveyor mechanism 2 located on one side of the crushing mechanism 1, and a visual monitoring mechanism 3 for detecting the size of the waste cathode carbon blocks is fixedly installed on the belt conveyor mechanism 2. The size of the waste cathode carbon blocks can be effectively monitored by the visual monitoring mechanism 3, so that the waste cathode carbon blocks with larger sizes can be effectively processed. A roller conveyor mechanism 4 is fixedly connected between the belt conveyor mechanism 2 and the feeding end of the crushing mechanism 1, wherein a collecting frame is fixedly installed on the roller conveyor mechanism 4, and the collecting frame is located below the roller conveyor mechanism 4. Since there is a gap between the rollers on the roller conveyor mechanism 4, smaller waste cathode carbon block fragments will fall from the gap between the rollers on the roller conveyor mechanism 4 into the collecting frame. Smaller waste cathode carbon block fragments entering the crushing mechanism 1 are prone to over-crushing, which affects Crushing uniformity; wherein a mounting frame 5 is fixedly installed on the roller conveying mechanism 4, and the mounting frame 5 is located above the roller conveying mechanism 4, and a plurality of lifting cutting mechanisms 6 are fixedly installed on the mounting frame 5 near the feeding end of the crushing mechanism 1, and the lifting cutting mechanism 6 is used to cut large-sized waste cathode carbon blocks. It should be noted that the lifting cutting mechanism 6 includes a cylinder fixedly installed on the top of the mounting frame 5, and a cutting part located inside the mounting frame 5 and fixedly connected to the output end of the cylinder, and then the cutting part can be effectively controlled by the cylinder to adjust the height. In the initial state (i.e., the normal-sized waste cathode carbon block is transported), the cutting part of the lifting cutting mechanism 6 is located at the highest point. At this time, the cutting part of the lifting cutting mechanism 6 will not be on the movement trajectory of the waste cathode carbon block. When encountering a larger-sized waste cathode carbon block, the cutting part on the lifting cutting mechanism 6 will be adjusted in height under the action of the cylinder, so that the cutting part is located at the movement trajectory of the larger-sized waste cathode carbon block. Combined with the attached Figure 3 As shown, the cutting part moves to the surface of the roller conveying mechanism 4 (the roller corresponding to the lifting cutting mechanism 6 is provided with a groove to facilitate the cutting of the waste cathode carbon block by the cutting part).

[0019] In order to cut and crush the larger-sized waste cathode carbon blocks, the present invention is provided with a plurality of clamping plate groups 7 for limiting the large-sized waste cathode carbon blocks inside the installation frame 5, and a plurality of driving parts 8 for controlling the height adjustment of the clamping plate groups 7 are provided inside the installation frame 5. The driving parts 8 control the clamping plate groups 7 to clamp and limit the large-sized waste cathode carbon blocks, so that the stabilized large-sized waste cathode carbon blocks are broken into small-sized waste cathode carbon blocks under the action of the lifting cutting mechanism 6.

[0020] In conjunction with the above, Figure 1As shown, the staff puts the recovered waste cathode carbon blocks on the belt conveyor mechanism 2, and the visual monitoring mechanism 3 is used to detect the size of the waste cathode carbon blocks on the belt conveyor mechanism 2. The detected waste cathode carbon blocks will enter the crushing mechanism 1 through the roller conveyor mechanism 4 for crushing, and the larger waste cathode carbon blocks will be cut and crushed, so that the large-sized waste cathode carbon blocks are cut and crushed into small pieces of waste cathode carbon blocks, which is convenient for the crushing mechanism 1 to crush the waste cathode carbon blocks. In the process of cutting and crushing the large-sized waste cathode carbon blocks, the splint group 7 can limit the large-sized waste cathode carbon blocks under the action of the driving part 8 to avoid shaking during the cutting process.

[0021] Further, as a further limitation in the present invention, the clamping plate group 7 is composed of a clamping plate A71 and a clamping plate B72, wherein the clamping plate A71 is closer to the lifting cutting mechanism 6 than the clamping plate B72, and a magnetic panel 73 is fixedly installed on the top of the clamping plate A71 and the clamping plate B72, and a strong magnetic plate 74 is fixedly installed on the side of the clamping plate A71 close to the clamping plate B72, and in the initial state (i.e., conveying of waste cathode carbon blocks of normal size), the clamping plate A71 and the clamping plate B72 will not be located on the conveying track of the waste cathode carbon blocks; As a further limitation of the present invention, each driving part 8 in the present invention includes two mobile frames 81, and the two mobile frames 81 correspond to the clamp A71 and the clamp B72 one by one, and the tops of the clamp A71 and the clamp B72 are respectively located in the corresponding mobile frames 81, that is, the clamp A71 is located in one of the mobile frames 81, and the clamp B72 is located in the other mobile frame 81, and an electric magnetic group 82 is fixedly installed on the top of each mobile frame 81, and the electric magnetic group 82 is located directly above the magnetic panel 73, and the electric magnetic group 82 generates a repulsive force on the magnetic panel 73 when it is energized, wherein a plastic spring 83 is connected between the magnetic panel 73 and the mobile frame 81, and a hole is opened in the central area of ​​the electric magnetic group 82, and the plastic spring is connected to the inner wall of the top of the mobile frame 81 through the hole, A slot 84 is provided on one side of one of the moving frames 81, and a force-bearing magnetic plate 85 is fixedly installed on the outer wall of one side of the other moving frame 81, and the force-bearing magnetic plate 85 corresponds to the slot 84, wherein the strong magnetic plate 74 can move to the corresponding position of the slot 84 during the descending process of the splint A71, and the magnetic poles of the strong magnetic plate 74 and the force-bearing magnetic plate 85 are opposite. A plurality of telescopic shafts 86 are also fixedly installed between the two moving frames 81, and the moving frame 81 is slidably connected to the inner wall of the top of the mounting frame 5, and a reset spring 87 is connected between one side of the moving frame 81 and the inner wall of the mounting frame 5, and an annular magnetic plate 88 is fixedly installed on the side wall of the moving frame 81 close to the lifting cutting mechanism 6, and an electromagnet body 9 is fixedly installed on the inner wall of the mounting frame 5, and the electromagnet body 9 generates an attractive force on the annular magnetic plate 88.

[0022] Combined with Figure 2 As shown, the large-sized waste cathode carbon blocks enter the installation frame 5, that is, the large-sized waste cathode carbon blocks can be transported under the action of the roller conveying mechanism 4. At this time, the visual monitoring mechanism 3 controls the electromagnetic component in one of the mobile frames 81 (that is, the mobile frame 81 corresponding to the clamp A71) to be energized in the form of an electrical signal. The electromagnetic component is energized to generate a repulsive force on the magnetic panel 73 on the top of the clamp A71, and the clamp A71 descends. At this time, the clamp A71 is located on the motion trajectory of the large-sized waste cathode carbon blocks. The waste cathode carbon blocks exert a force on the clamp A71, and then the clamp A71 and the corresponding mobile frame 8 1 performs directional movement in the installation frame 5. During the movement of the mobile frame 81, the reset spring 87 is squeezed, and the mobile frames 81 are connected by the telescopic shaft 86, so that the two mobile frames 81 move synchronously. The electromagnetic component in the other mobile frame 81 (i.e., the mobile frame 81 corresponding to the clamping plate B72) is energized, so that the clamping plate B72 moves downward. At this time, the large-sized waste cathode carbon block is located between the clamping plate A71 and the clamping plate B72, but there is a width difference between the large-sized waste cathode carbon block, that is, the clamping plate A71 and the clamping plate B72 may not completely limit the waste cathode carbon block. Figure 4 and attached Figure 5 As shown, during the descent of the splint A71, the strong magnetic plate 74 on one side of the splint A71 is close to the slot 84. When the splint A71 is descended to the lowest point, the strong magnetic plate 74 moves to the corresponding position of the slot 84. The strong magnetic plate 74 generates an attractive force on the force-bearing magnetic plate 85 on the side wall of the other mobile frame 81 (i.e., the mobile frame 81 corresponding to the splint B72). Then, the other mobile frame 81 drives the splint B72 to move closer to the splint A71 under the action of the force-bearing magnetic plate 85, and the splint B72 finally contacts with the waste cathode carbon block and exerts a force on it, so that the waste cathode carbon block is limited by the splint A71 and the splint B72. During this process, the telescopic shaft 86 is in a contracted state. Figure 2 , Attachment Figure 4 , Attachment Figure 6 and attached Figure 7As shown, when the waste cathode carbon blocks are close to the lifting cutting mechanism 6, the power of the roller conveying mechanism 4 alone may not be able to support the cutting work of the waste cathode carbon blocks (the waste cathode carbon blocks will be subject to resistance given by the lifting cutting mechanism 6 during the cutting process), and then when the splint A71 is close to the lifting cutting mechanism 6, the electromagnet body 9 fixedly installed on the inner wall of the mounting frame 5 will be energized to generate an attractive force on the annular magnetic plate 88, and then one of the moving frames 81 drives the other moving frame 81 to move through the telescopic shaft 86, so that the splint A71 and the splint B72 drive the waste cathode carbon blocks to move toward the lifting cutting mechanism 6, under the action of the splint A71 and the splint B72, the large-sized waste cathode carbon blocks are cut and broken into small pieces of waste cathode carbon blocks by the lifting cutting mechanism 6, so that the crushing mechanism 1 can crush the waste cathode carbon blocks, which can effectively reduce the probability of uneven distribution of particle size after crushing, improve the crushing quality of the waste cathode carbon blocks, and facilitate subsequent grinding work.

[0023] In the process of crushing the waste cathode carbon block, there may still be slight differences in the particle size after crushing. In order to refine the grinding, the staff usually adds a screen for screening. However, in actual use, the particle size after crushing is usually affected by multiple factors, that is, the particle size has a certain change, and the screen in the prior art cannot effectively change the sieve holes according to the needs, and then the particles of different sizes are often mixed. In order to improve the grinding quality, the present invention designs the aperture of the screen so that the aperture of the screen can be adjusted accordingly according to the actual needs, and then in the subsequent grinding process, the probability of the particles of different sizes being mixed can be effectively reduced, so as to achieve the purpose of improving the grinding quality; based on this, the present invention carries out the following design: A collecting chamber 10 is arranged below the crushing mechanism 1, and the feeding end of the collecting chamber 10 is in communication with the discharging end of the crushing mechanism 1, and a plurality of sieve plate portions 11 are installed inside the collecting chamber 10, and a discharging channel 101 corresponding to the plurality of sieve plate portions 11 is installed on the side wall of the collecting chamber 10. Figure 8As shown, the sieve plate portion 11 is installed in a downwardly inclined state in the collecting chamber 10, and the sieve plate portion 11 includes a fixed frame 111 fixedly installed inside the collecting chamber 10, and a plurality of diamond plates A112 and diamond plates B113 are arranged inside each fixed frame 111, and the diamond plates A112 and the diamond plates B113 are arranged in a staggered manner, and the diamond plates B113 are fixedly connected to the inner wall of the fixed frame 111, so that the gap between the diamond plates A112 and the diamond plates B113 is a screening channel. In order to prevent particles with a size similar to the gap between the diamond plates A112 and the diamond plates B113 from being stuck in the screening channel, the present invention has a protrusion 1 fixedly installed on the side wall of each diamond plate B113. 10. Both sides of the fixed frame 111 are provided with cavities 114, and a plurality of sealing rubbers 115 corresponding to the diamond plates A112 are fixedly installed on the side walls of the cavities 114. Both ends of each diamond plate A112 are fixedly installed with connecting shafts 116, and the ends of the connecting shafts 116 penetrate the sealing rubbers 115 and extend into the cavity 114. An electromagnetic plate frame 117 is fixedly installed on the inner wall of the end of the cavity 114, and a movable plate frame 118 slidably connected to the inner wall thereof is also installed inside the cavity 114, and the end of the movable plate frame 118 close to the electromagnetic plate frame 117 is a magnetic end, and an inclined slot 119 is also provided on the movable plate frame 118, and the connecting shaft 116 is located in the inclined slot 119; Combined with Figure 8 As shown, the crushed waste cathode carbon block particles enter the collection chamber 10 through the discharge end, and then pass through multiple sieve plate parts 11 for screening. During this process, the waste cathode carbon block particles that meet the size requirements will pass through the gap between the diamond plate A112 and the diamond plate B113 (i.e., the screening channel) to achieve screening, and the waste cathode carbon block particles that do not meet the size requirements will move along the inclined surface of the diamond plate A112 and the diamond plate B113, and finally move to the discharge channel 101. When the staff needs to adjust the gap between the diamond plate A112 and the diamond plate B113 according to needs (i.e., adjust the size of the screening channel), the staff can adjust the electromagnetic plate frame 117. When the power is turned on, the magnetic poles of the electromagnetic plate frame 117 can be adjusted by changing the direction of the current. When the electromagnetic plate frame 117 is powered on, the magnetic ends of the mobile plate frame 118 will be subjected to the force of attraction or repulsion, so that the mobile plate frame 118 will make a directional movement close to or away from the electromagnetic plate frame 117, and the inclined groove 119 on the mobile plate frame 118 will exert a force on the connecting shaft 116, and the connecting shaft 116 will drive the diamond plate A112 to move up or down. In this process, the connecting shaft 116 will squeeze the sealing rubber 115. Due to its own deformability, the connecting shaft 116 can adjust the position accordingly in the sealing rubber 115. Fig.13As shown, after the position of diamond plate A112 is adjusted, the gap between diamond plate A112 and diamond plate B113 will change. Therefore, in actual use, the staff can adjust the gap between diamond plate A112 and diamond plate B113 (i.e., the screening channel) according to actual needs to avoid mixing of waste cathode carbon block particles of different sizes, so as to achieve the purpose of improving the grinding quality.
