Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and specifically to an electrolytic aluminum anode stub crushing, recycling and processing device and its processing method. Background Art

[0002] During the electrolysis of aluminum, the actual consumption of the carbon anode is much higher than its theoretical consumption, which directly affects the production of primary aluminum. The anode carbon is a consumable in the electrolytic aluminum industry, and a large amount of waste anode stubs are generated every year. Although these anode stubs can no longer be used for electrolytic aluminum, they have other application values. Because the calorific value of carbon is relatively high, even if it is sold as fuel, considerable economic benefits can still be obtained. Therefore, many units and individuals are engaged in the recycling and processing of electrolytic aluminum anode stubs and have achieved rich profits.

[0003] The recycling and processing of electrolytic aluminum anode stubs mainly involve crushing the anode stubs and then decomposing the electrolyte therein to improve the carbon impurity and calorific value. The carbon and electrolyte can be sold separately for profit, which is the fundamental way for the recycling and utilization of electrolytic aluminum anode stubs.

[0004] Due to the characteristics of simple structure, light weight, low price, reliable operation, and convenient crushing ratio of the roll crusher, it is a good choice for crushing anode stubs. Before the crushing process, the staff will adjust the distance between the two rolls according to the relevant requirements of crushing. When encountering anode stubs with larger specifications or other harder impurities doped in the anode stubs during the crushing process, it will cause serious damage to the two rolls and even lead to the problem of motor burnout, resulting in high equipment failure rate, short service life, and high maintenance cost for the enterprise. Summary of the Invention

[0005] The purpose of the present invention is to provide an electrolytic aluminum anode stub crushing, recycling and processing device and its processing method to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0015] As a further solution of the present invention: The centrifugal trigger structure includes a rotating shaft rotatably installed on the support frame, a rotating plate fixedly installed on the rotating shaft, and a collar sleeved on the sieve cylinder. A connecting plate is fixed on the collar. The connecting plate is rotatably connected to a sliding tube slidably arranged on the rotating shaft, and the sliding tube is connected to an elastic member arranged on the rotating plate. The rotating shaft is connected to the second lead screw through a fourth transmission belt.

[0016] As a further solution of the present invention: The elastic member includes a guide rod fixedly installed on the rotating plate, a driven block slidably arranged on the guide rod, and a cylindrical spring sleeved on the outer periphery of the guide rod. One end of the cylindrical spring is connected to the driven block, and the other end is connected to the rotating plate. A push-pull rod is arranged between the driven block and the sliding tube. The head end of the push-pull rod is hinged to the driven block, and the tail end is hinged to the sliding tube.

[0017] As a further solution of the present invention: One through groove is provided on each side of the box body. A slider is slidably fitted in each of the two through grooves. The second crushing roller is rotatably installed between the two sliders;

[0018] The transverse movement driving mechanism includes a first lead screw rotatably installed on the outer wall of the box body and a threaded sleeve sleeved on the first lead screw, and the threaded sleeve is fixedly connected to the slider.

[0019] As a further solution of the present invention: The one-way trigger mechanism includes a transmission plate fixedly installed on the transverse movement plate and a ratchet wheel rotatably installed on the support frame.

[0021] As a further solution of the present invention: The rotating connection assembly includes a first connecting rod and a second connecting rod rotatably connected at the head end through a shaft member. The tail end of the first connecting rod is rotatably connected to the rotating shaft of the second gear, and the tail end of the second connecting rod is rotatably connected to the rotating shaft of the second crushing roller. And the shaft member is connected to the rotating shaft of the second gear through a first transmission belt and is also connected to the rotating shaft of the second crushing roller through a second transmission belt.

[0022] A method for recycling electrolytic aluminum anode stubs by crushing, using the described processing equipment, includes the following steps:

[0023] Step 1: Start the first motor to perform primary crushing on the anode stubs, and the crushed anode stubs enter the screening cylinder.

[0024] Step 2: The screening cylinder rotates to screen the anode stubs inside it, and the anode stubs that can pass through the screening holes enter the next processing line.

[0025] Step 3: Start the pushing mechanism to discharge the anode stubs that cannot pass through the screening holes in the screening cylinder into the auger, and the auger conveys the anode stubs back into the box. At the same time, the one-way triggering mechanism is triggered, prompting the transverse movement driving mechanism to drive the second crushing roller towards the first crushing roller, and the distance between the first crushing roller and the second crushing roller decreases.

[0026] Step 4: Repeat the above steps until all anode stubs can pass through the screening holes on the screening cylinder and reach the upper position of the next processing line.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. During use, the screening cylinder is used to screen the crushed anode stubs, so that the non-compliant anode stubs are conveyed back into the box by the auger for re-crushing. And before each repeated crushing process, the transverse movement driving mechanism will drive the second crushing roller to move a certain distance towards the first crushing roller. Thus, during the entire processing process, the distance between the first crushing roller and the second crushing roller shows a gradually decreasing trend, realizing the progressive crushing function of the anode stubs. On the one hand, it can effectively avoid serious damage to the tooth edges on the first crushing roller and the second crushing roller due to the relatively large initial specifications of the anode stubs. On the other hand, it can effectively reduce the load on the first motor. Therefore, this equipment has a low failure rate and a long service life, can effectively reduce the maintenance cost in enterprise production, and is suitable for popularization and use.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] In addition, the elements in the present invention are referred to as "fixed to" or "arranged on" another element, and it can be directly on another element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to another element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation mode.

[0041] In an embodiment of the present invention, an electrolytic aluminum anode scrap crushing and recycling treatment device includes a base 1, a support frame 2 fixedly arranged on the base 1, a box body 3 installed on the support frame 2, and a screw conveyor 4 installed on the base 1. It further includes a first crushing roller 6, a second crushing roller 7, a lateral movement driving mechanism, a transmission mechanism, a sieve cylinder 21, a pushing mechanism, a one-way triggering mechanism, and a first motor 8;

[0042] Among them, the sieve cylinder 21 is used to screen the crushed anode scraps, so that the unqualified anode scraps are re-transported by the screw conveyor 4 into the box body 3 for re-crushing. And before each repeated crushing treatment, the lateral movement driving mechanism will drive the second crushing roller 7 to move a certain distance towards the first crushing roller 6. Thus, during the whole processing process, the distance between the first crushing roller 6 and the second crushing roller 7 shows a gradually decreasing trend, realizing the progressive crushing function of the anode scraps. On the one hand, it can effectively avoid serious damage to the tooth edges on the first crushing roller 6 and the second crushing roller 7 due to the relatively large initial specifications of the anode scraps. On the other hand, it can effectively reduce the load of the first motor 8 (when there are impurities with higher hardness doped in the anode scraps, it may even cause the first motor 8 to burn out). Therefore, the failure rate of this device is low and the service life is long, which can effectively reduce the maintenance cost in enterprise production and is suitable for popularization and use.

[0043] Specifically, please refer to Figures 1-10 , and the following detailed introduction will be made:

[0044] The first crushing roller 6 is rotatably installed in the box body 3, and its rotating shaft is connected to the output end of the first motor 8 installed on the box body 3. The second crushing roller 7 is connected to the lateral movement driving mechanism installed on the box body 3. The transmission mechanism is arranged between the rotating shafts of the first crushing roller 6 and the second crushing roller 7. The lateral movement driving mechanism can drive the second crushing roller 7 to move closer to or away from the first crushing roller 6, so that the distance between the first crushing roller 6 and the second crushing roller 7 decreases or increases;

[0045] The sieve cylinder 21 is rotatably installed on the support frame 2 and located between the base 1 and the box body 3, and is used for screening the waste anodes that have passed through the first crushing roller 6 and the second crushing roller 7. The pushing mechanism is installed on the support frame 2 and is used to push the waste anodes that are in the sieve cylinder 21 and cannot pass through the sieve holes into the auger 4, so that the auger 4 conveys the waste anodes into the box body 3, forming a circulating crushing line for the waste anodes;

[0046] The one-way trigger mechanism is arranged between the pushing mechanism and the transverse movement driving mechanism, and the one-way trigger mechanism is triggered after the waste anodes in the sieve cylinder 21 are pushed out, so that the transverse movement driving mechanism drives the second crushing roller 7 to move away from the first crushing roller 6, and the distance between the first crushing roller 6 and the second crushing roller 7 is increased.

[0047] It should be added that a discharge channel is also provided on the base 1, and the width of the discharge channel covers the distribution range of the sieve holes on the sieve cylinder 21, so as to ensure that when the sieve cylinder 21 rotates and screens the waste anodes, the waste anodes that can pass through the sieve holes can be transmitted to the next processing line through the discharge channel;

[0048] Secondly, a receiving hopper is also provided on the base 1. The receiving hopper is used to receive the waste anodes pushed out by the pushing mechanism (that is, the waste anodes that are in the sieve cylinder 21 and cannot pass through the sieve holes), and the receiving hopper is connected to the inlet of the auger 4. The auger 4 is a screw conveyor, and a feeding chute is provided at the outlet at the upper end thereof, and the tail end of the feeding chute corresponds to the feeding hopper 303 provided on the box body 3;

[0049] In addition, a first baffle 301 and a second baffle 302 are fixedly installed on the bottom wall of the box body 3. The first baffle 301 and the second baffle 302 are provided to guide the waste anodes that have passed through the first crushing roller 6 and the second crushing roller 7, and ensure that the waste anodes can smoothly enter the sieve cylinder 21.

[0050] During actual processing, the waste anode to be processed is added to the hopper 303. Subsequently, the first crushing roller 6 and the second crushing roller 7 rotate synchronously and in opposite directions to crush the waste anode. The crushed waste anode then enters the screening cylinder 21. Subsequently, the screening cylinder 21 rotates to effectively screen the waste anode therein. The waste anode that can pass through the screen holes meets the crushing requirements (i.e., reaches the corresponding particle size). The waste anode that cannot pass through the screen holes is pushed out into the auger 4 by the pushing mechanism during operation, and then re-transported by the auger 4 into the hopper 303 for secondary crushing treatment. During this process, the one-way trigger mechanism is triggered to drive the transverse movement drive mechanism to move. The transverse movement drive mechanism will drive the second crushing roller 7 to move a certain distance towards the first crushing roller 6, reducing the distance between the first crushing roller 6 and the second crushing roller 7 to facilitate more refined secondary crushing treatment. This process is repeated until all the waste anodes are crushed to be able to pass through the screen holes, indicating that the processing is completed.

[0051] It should also be emphasized that since the crushing treatment of the waste anode by this equipment is progressive, that is, the waste anode needs to go through several cycles to complete the crushing treatment. Therefore, in actual use, the quantity of the waste anode processed each time needs to be controlled to avoid excessive quantity of the waste anode added to the hopper 303 at a single time, which may cause the screening cylinder 21 to be unable to hold it, and too much waste anode in the screening cylinder 21 will also lead to poor screening effect.

[0052] Please refer to again Figure 8 , one end of the screening cylinder 21 is provided with a plurality of feed ports 2102, the other end is provided with a discharge port 2101, and a ring body 5 fixed to the bottom of the box body 3 is also sleeved on the screening cylinder 21. The ring body 5 is used to introduce the waste anode in the box body 3 into the screening cylinder 21 through the feed ports 2102. The pushing mechanism can switch the blocking and conducting states of the discharge port 2101. A second motor 22 is also installed on one side of the support frame 2, and the rotating shaft of the screening cylinder 21 is connected to the output end of the second motor 22.

[0053] Please refer to again Figure 3 , Figure 4 , Figure 7 and Figure 8, the pushing mechanism includes a second lead screw 26 rotatably mounted on the support frame 2, a transverse movement plate 25 provided on the second lead screw 26 and threadedly connected to the second lead screw 26, and a disc 23 fixedly connected to the transverse movement plate 25 through a connecting plate 24. The disc 23 is located inside the screening cylinder 21. A third motor 27 with an output end connected to the second lead screw 26 is also mounted on the support frame 2, and one end of the second lead screw 26 away from the third motor 27 is connected with a centrifugal trigger structure, which is used to switch the blocking and conducting states of the discharge port 2101.

[0054] It should be noted that, in order to ensure the stable movement of the disc 23 inside the screening cylinder 21, the inner side of the connecting plate 24 and the support frame 2 are in a sliding fit state, so as to ensure that when the third motor 27 drives the second lead screw 26 to rotate, the transverse movement plate 25 and the second lead screw 26 can smoothly perform thread engagement.

[0055] Whenever the screening cylinder 21 stops rotating (that is, after the screening of the residual anodes inside it is completed), the third motor 27 (servo motor) starts to work, driving the second lead screw 26 to rotate, so that the transverse movement plate 25 and the second lead screw 26 perform thread engagement, and the disc 23 is driven through the connecting plate 24 to complete a round-trip movement inside the screening cylinder 21. During this process, the second lead screw 26 drives the centrifugal trigger structure to move, and the centrifugal trigger structure switches the blocking state of the discharge port 2101 to the conducting state, so that the disc 23 smoothly pushes the residual anodes inside the screening cylinder 21 through the discharge port 2101 into the auger 4.

[0056] It should be emphasized that during the screening process of the residual anodes by the screening cylinder 21, the number of turns that the second motor 22 needs to drive the screening cylinder 21 to rotate is an integer, ensuring that after the screening process ends, the discharge port 2101 faces downward, so that the residual anodes inside the screening cylinder 21 can be smoothly discharged.

[0057] Please refer to again Figure 6 , the centrifugal trigger structure includes a rotating shaft 31 rotatably mounted on the support frame 2, a rotating plate 32 fixedly mounted on the rotating shaft 31, and a collar 40 sleeved on the screening cylinder 21. A connecting plate 39 is fixed on the collar 40, the connecting plate 39 is rotatably connected to a sliding tube 37 slidably arranged on the rotating shaft 31, and the sliding tube 37 is connected with an elastic member arranged on the rotating plate 32. The rotating shaft 31 is connected to the second lead screw 26 through a fourth transmission belt 33.

[0058] The elastic member includes a guide rod 34 fixedly installed on the rotating plate 32, a driven block 35 slidably disposed on the guide rod 34, and a cylindrical spring 36 sleeved on the outer periphery of the guide rod 34. One end of the cylindrical spring 36 is connected to the driven block 35, and the other end is connected to the rotating plate 32. A push-pull rod 38 is provided between the driven block 35 and the sliding tube 37. The head end of the push-pull rod 38 is hinged to the driven block 35, and the tail end is hinged to the sliding tube 37.

[0059] When the second lead screw 26 rotates, the rotating shaft 31 can be driven to rotate through the fourth transmission belt 33. Under the action of centrifugal force, the driven block 35 slides away from the rotating shaft 31 on the guide rod 34, and the cylindrical spring 36 is compressed. Correspondingly, the driven block 35 drives the sliding tube 37 to slide on the rotating shaft 31 toward the rotating plate 32 through the push-pull rod 38, and the sliding tube 37 can drive the collar 40 to slide on the sieve cylinder 21 through the connecting plate 39, so that the collar 40 is staggered from the discharge port 2101, facilitating the smooth export of the residual electrodes in the sieve cylinder 21 to the auger 4 under the push of the disc 23 for the next round of crushing.

[0060] Please refer to again Figure 3 、 Figure 4 、 Figure 7 and Figure 9 As shown in, one through groove is provided on each side of the box body 3, and a slider 9 is slidably fitted in each of the two through grooves. The second crushing roller 7 is rotatably installed between the two sliders 9. The transverse movement driving mechanism includes a first lead screw 18 rotatably installed on the outer wall of the box body 3 and a threaded sleeve 19 sleeved on the first lead screw 18, and the threaded sleeve 19 is fixedly connected to the slider 9.

[0061] The one-way triggering mechanism includes a transmission plate 28 fixedly installed on the transverse movement plate 25 and a ratchet wheel 30 rotatably installed on the support frame 2. The rotating shaft of the ratchet wheel 30 is connected through a third transmission belt 29 to a transmission shaft 10 rotatably installed on the box body 3, and the transmission shaft 10 is connected to the first lead screw 18 through a bevel gear set 20.

[0062] Furthermore, the bevel gear set 20 includes a first bevel gear fixedly installed on the transmission shaft 10 and a second bevel gear fixedly installed at one end of the first lead screw 18 facing the transmission shaft 10, and the second bevel gear meshes with the first bevel gear.

[0063] A plurality of inclined grooves are equidistantly provided on the transmission plate 28, and a ratchet pawl cooperating with the ratchet wheel 30 is hinged in each inclined groove.

[0064] When the disk 23 moves towards the inside of the sieve cylinder 21, the ratchet pawl on the transmission plate 28 will pass by the ratchet wheel 30. At this time, the ratchet pawl will flip when passing by the ratchet wheel 30, so that the ratchet wheel 30 does not rotate.

[0065] On the contrary, after the disk 23 finishes pushing out the residual anodes in the sieve cylinder 21 and moves back towards the outside of the sieve cylinder 21 during the reset process, at this time, the ratchet pawl cannot flip when passing by the ratchet wheel 30. Furthermore, the ratchet wheel 30 will rotate, and its rotating shaft drives the transmission shaft 10 through the third transmission belt 29. The transmission shaft 10 is connected to the first lead screw 18 through the bevel gear set 20. Then, the threaded sleeve 19 will be in threaded cooperation with the first lead screw 18, so that the slider 9 drives the second crushing roller 7 to move closer to the first crushing roller 6 by a certain distance, reducing the distance between the first crushing roller 6 and the second crushing roller 7 to further crush the residual anodes.

[0066] After the crushing process is completed, for the convenience of the next use, the staff needs to rotate the first lead screw 18 to facilitate the movement of the second crushing roller 7 away from the first crushing roller 6 for reset.

[0067] The transmission mechanism includes a gear set structure connected to the rotating shaft of the first crushing roller 6 and a rotating connection component connecting the gear set structure and the rotating shaft of the second crushing roller 7. The gear set structure includes a first gear 11 fixedly installed on the rotating shaft of the first crushing roller 6 and a second gear 12 rotatably installed on the box body 3 and meshing with the first gear 11. The rotating connection component includes a first connecting rod 14 and a second connecting rod 15 whose heads are rotatably connected by a shaft member 13. The tail end of the first connecting rod 14 is rotatably connected to the rotating shaft of the second gear 12, and the tail end of the second connecting rod 15 is rotatably connected to the rotating shaft of the second crushing roller 7. And the shaft member 13 is connected to the rotating shaft of the second gear 12 through the first transmission belt 16 and is also connected to the rotating shaft of the second crushing roller 7 through the second transmission belt 17.

[0068] When performing the crushing process, the first motor 8 works to drive the first crushing roller 6 to rotate clockwise. Then, the rotating shaft of the first crushing roller 6 will drive the second gear 12 to rotate counterclockwise through the first gear 11. Thus, the rotating shaft of the second gear 12 will drive the second crushing roller 7 to rotate counterclockwise through the first transmission belt 16, the shaft member 13, and the second transmission belt 17. The rotating directions of the first crushing roller 6 and the second crushing roller 7 are opposite to effectively play the role of crushing the residual anodes (please refer to Figure 10 ).

[0069] Among them, when the first lead screw 18 rotates to make the second crushing roller 7 move closer to or away from the first crushing roller 6, the first connecting rod 14 and the second connecting rod 15 will rotate through the shaft member 13, and the angle between them will change to ensure the maintenance of the transmission connection state between the first crushing roller 6 and the second crushing roller 7.

[0070] As another embodiment of the present invention, a method for recycling electrolytic aluminum anode residues by crushing is also proposed. Using the processing equipment described above, it includes the following steps:

[0071] Step 1: Start the first motor 8 to perform primary crushing on the anode residues, and the crushed anode residues enter the screening cylinder 21.

[0072] Step 2: The screening cylinder 21 rotates to screen the anode residues inside it, and the anode residues that can pass through the screen holes enter the next processing line.

[0073] Step 3: Start the pushing mechanism to discharge the anode residues that cannot pass through the screen holes in the screening cylinder 21 into the auger 4, and the auger 4 conveys the anode residues back into the box body 3. At the same time, the one-way triggering mechanism is triggered to prompt the transverse movement driving mechanism to drive the second crushing roller 7 to move towards the first crushing roller 6, and the distance between the first crushing roller 6 and the second crushing roller 7 decreases.

[0074] Step 4: Repeat the above steps until all the anode residues can pass through the screen holes on the screening cylinder 21 and reach the upper position of the next processing line.

[0075] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
