Description

Technical Field

[0001] The invention relates to the technical field of carbon black crushing, in particular to a carbon black crusher for recycling waste tires. Background Art

[0002] In the process of recycling waste tires, the acquisition and crushing of carbon black are important links. After recycling, waste tires are first cracked to extract by-products such as carbon black. Then, the coarse carbon black particles are finely ground using a carbon black crusher. The crushed carbon black particles are finally produced through a series of processes such as packaging to meet the needs of different industrial applications.

[0003] In the process of using a pulverizer to pulverize carbon black, traditional carbon black pulverizers often use a continuous feeding method through a conveying device to allow carbon black to continuously enter the pulverizing chamber through the feed port and be pulverized by the pulverizing rollers. The continuous feeding method often leads to excessive accumulation of carbon black between the two pulverizing rollers. The pulverizing rollers are unable to process the carbon black in time, which will cause congestion of the carbon black particles between the two pulverizing rollers, thereby affecting the normal operation of the pulverizing rollers, which not only reduces the pulverizing efficiency, but also causes the pulverizing rollers to overload, accelerate their wear, and even cause equipment failure. At the same time, due to the continuous feeding, the input amount of carbon black particles will become unstable, resulting in uneven feeding of carbon black particles, which will directly affect the pulverizing effect of the pulverizing rollers on carbon black, resulting in uneven particle size distribution of the final product, affecting product quality.

[0040] The effects achieved by this embodiment are as follows: compared with the prior art, by dynamically adjusting the setting of the cyclic opening and closing mechanism 5, while the crushing roller 3 is operating, the push block 507 arranged for horizontal reciprocating movement is used to intermittently twist and rotate the triangular plate 510, and the push rod 511 is simultaneously driven to intermittently lift and push the sealing plate 514, so that the sealing plate 514 can be dynamically opened and closed at the lower end of the feed port 2, thereby intermittently feeding the carbon black, which is different from the traditional method of continuous feeding. It can maintain the uniformity of the input of carbon black particles during the crushing process, and effectively avoid overloading or clogging of the crushing roller 3 due to excessive carbon black, so that the carbon black can be stably crushed.

[0041] For further examples, please refer to Figures 1 to 9 As shown, the contact-type speed monitoring dynamic sensing mechanism 6 includes a second driven disk 601 arranged between the crushing box 1 and the first driven disk 502, and the second driven disk 601 is coaxially fixedly connected to the outer surface of the linkage shaft 501, an L-shaped fixing frame 603 is fixedly connected to the lower end of the front side of the crushing box 1, and the L-shaped fixing frame 603 is arranged on the right side of the second driven disk 601, an L-shaped sleeve 604 is fixedly connected to the front side of the L-shaped fixing frame 603, and T-shaped slide bars 605 are symmetrically penetrated and slidably connected at both ends of the L-shaped sleeve 604, a return spring 607 is fixedly connected between one end of the T-shaped slide bar 605 away from the L-shaped sleeve 604 and the L-shaped sleeve 604, and the return spring 607 is sleeved on the outer surface of the T-shaped slide bar 605.

[0042] One end of one of the T-shaped slide bars 605 facing the second driven disk 601 is fixedly connected with a pressure ball 606 , and the outer surface of the second driven disk 601 is annularly and equidistantly fixedly connected with an extrusion bevel block 602 , and the extrusion bevel block 602 is used to push the pressure ball 606 to move.

[0043] A mounting plate 609 is fixedly connected to the front side of the crushing box 1, and the mounting plate 609 is arranged above the end of the L-shaped sleeve 604 away from the second driven disk 601. A warning light 610 is fixedly connected to the top of the mounting plate 609, and contacts 608 are arranged on the opposite sides of the other T-shaped sliding bar 605 and the mounting plate 609.

[0044] The effects achieved by this embodiment are as follows: compared with the prior art, through the setting of the contact-type speed monitoring dynamic sensing mechanism 6, while the crushing roller 3 operates to intermittently discharge carbon black particles, the extrusion bevel block 602 is used to squeeze and push the compressed ball 606, and the T-shaped slide bar 605 and the contact 608 on the mounting plate 609 are synchronously driven to contact each other so that the warning light 610 is always on, which enables the staff to monitor the rotation speed of the crushing roller 3 in real time according to the lighting status of the warning light 610. By using direct physical contact to sense the change in speed, the actual rotation of the crushing roller 3 can be more accurately reflected, thereby avoiding the abnormally slow speed of the crushing roller 3 for a long time, resulting in equipment failure, reduced production efficiency and even safety accidents.

[0045] For further examples, please refer to Figures 1 to 9 As shown, the adaptive dust accumulation trigger reminder mechanism 7 includes a support block 701 fixedly connected to the right inner wall of the crushing box 1, the left side of the support block 701 is set as an inclined surface, and a slide groove 702 is provided on the inclined surface of the left side of the support block 701, a slider 704 is slidably connected in the slide groove 702, and a collecting plate 706 is clamped on the side of the slider 704 away from the support block 701, an elastic telescopic column 705 is fixedly connected between the slider 704 and the inner bottom wall of the slide groove 702, and a switch 703 is provided at the lower end of the groove wall on the side of the slide groove 702 away from the collecting plate 706, and the switch 703 is electrically connected to the external reminder.

[0046] Filter holes 707 are evenly formed on one side of the collecting plate 706 away from the supporting block 701 , a cavity 708 is provided inside the collecting plate 706 , and the cavity 708 is connected to the filter holes 707 , and the cavity 708 is used to collect dust in the carbon black.

[0047] The effects achieved by this embodiment are as follows: compared with the prior art, through the setting of the adaptive dust accumulation trigger reminder mechanism 7, when the carbon black particles are discharged through the feed port 2 and fall onto the collecting plate 706 via the inclined path of the blocking plate 514, the inclination of the collecting plate 706, combined with the design of the filter holes 707 and the cavity 708, can screen the fallen carbon black particles, collect the dust in the carbon black particles and deposit them in the cavity 708, avoid the dust from flying around and causing the dust to float on the surfaces of various components inside the crushing box 1, causing interference and damage to the internal structure of the crushing box 1, and reduce the concentration of suspended dust in the air, thereby helping to protect the health of the workers.

[0048] At the same time, the collecting plate 706 is supported by the slider 704 and the elastic telescopic column 705 and is slidably set in the slide groove 702, and a switch 703 is set in the slide groove 702. When the dust deposited in the cavity 708 increases due to long-term use, the collecting plate 706 will cooperate with the slider 704 to move synchronously along the path opened by the slide groove 702, and touch the switch 703 to turn on the external reminder, so as to remind the staff that there is too much dust accumulated on the collecting plate 706 and it needs to be replaced or cleaned in time, thereby reducing the tediousness and omissions of manual inspection and reducing the difficulty of cleaning the dust.

[0049] The complete usage steps and working principles of the above embodiment are as follows: The following is the working process of dynamically adjusting the opening and closing of the feed port 2 by the dynamic control cycle opening and closing mechanism 5 according to the rotational movement of the crushing roller 3: It should be explained in advance that a drive motor is fixedly arranged on the rear side of the crushing box 1, and the output end of the drive motor is fixedly connected to one of the crushing rollers 3, and a transmission member is arranged between the two crushing rollers 3. When in use, one of the crushing rollers 3 can be driven to rotate on the crushing box 1 through the operation of the drive motor, and the other crushing roller 3 can be driven to rotate synchronously through the transmission of the transmission member. The carbon black produced after the recycling of waste tires is transported to the feed port 2 through an external conveying device, and the carbon black is discharged into the crushing box 1 through the feed port 2.

[0050] When the pulverizing roller 3 rotates inside the pulverizing box 1 and pulverizes the carbon black fed through the feed port 2, Figure 2 and Figure 3 As shown, since a linkage shaft 501 is rotatably provided on the front side of the crushing box 1, and the linkage shaft 501 is fixedly connected to one of the crushing rollers 3, when the crushing roller 3 rotates, the linkage shaft 501 rotates synchronously with the front side of the crushing box 1, and the first driven disk 502 fixedly provided on its outer surface is synchronously driven to rotate. In addition, since a lever 503 is fixedly provided eccentrically on the disk surface of the first driven disk 502 away from the crushing roller 3, and a frame-shaped slide 504 is slidably provided on the outer surface of the lever 503, when the first driven disk 502 rotates synchronously with the rotation of the linkage shaft 501, the lever 503 also performs a circular motion with the linkage shaft 501 as the axis, thereby utilizing the relationship of the sliding connection to drive the first driven disk 502 to rotate synchronously. The frame slide 504 is made to move back and forth horizontally on the front side of the first driven disk 502. Since a limiting horizontal plate 505 is symmetrically fixedly arranged on the front side of the crushing box 1 with the axis of the first driven disk 502 as the center, and the frame slide 504 is slidably arranged between the upper and lower limiting horizontal plates 505, when the lever 503 moves to push the frame slide 504 to move, the two ends of the frame slide 504 will slide synchronously on the two limiting horizontal plates 505 respectively, so that the setting of the limiting horizontal plate 505 can provide moving support for the frame slide 504, and the moving range of the frame slide 504 can be further limited, so that the frame slide 504 can be more stable and smooth when moving.

[0051] like Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a push block 507 is fixedly provided on the top of the frame-shaped slide 504 through an extension rod 506, a connecting shaft 508 is rotatably provided on the upper end of the front side of the crushing box 1, and a triangular plate 510 is fixedly provided on the outer surface of the connecting shaft 508, and a torsion spring 509 is fixedly provided between the triangular plate 510 and the crushing box 1 and sleeved on the outer surface of the connecting shaft 508. The lower end of the triangular plate 510 is as shown in FIG. Figure 2 As shown, the push block 507 is arranged on the right side. When the frame-shaped slide 504 moves back and forth horizontally between the two limit horizontal plates 505, the push block 507 can be synchronously followed by the movement through the connection of the extension rod 506, and approaches the direction of the triangular plate 510. When the push block 507 contacts the outer surface of the lower end of the triangular plate 510, as the frame-shaped slide 504 continues to move, the push block 507 will generate a rightward thrust on the lower end of the triangular plate 510. Under the pushing action of the push block 507, the triangular plate 510 can rotate at the front side of the crushing box 1 with the connecting shaft 508 as the axis. At this time, the torsion spring 509 synchronously cooperates with the rotation of the connecting shaft 508 to A torsional movement occurs between the box 1 and the triangular plate 510. Because arc grooves 512 are symmetrically opened on both sides of the upper end of the crushing box 1, and a push rod 511 is slidably set between the arc grooves 512, and the front end of the push rod 511 passes through the arc groove 512 and is fixedly connected to the triangular plate 510 (that is, a connecting shaft 508 is set at the upper corner of the left side of the triangular plate 510, the lower corner of the left side of the triangular plate 510 is set close to the push block 507, and the push rod 511 is set at the upper corner of the right side of the triangular plate 510). When the triangular plate 510 rotates with the connecting shaft 508 as the axis, the push rod 511 will synchronously slide in the path opened by the arc groove 512 and gradually slide to the uppermost position of the arc groove 512, such as Figure 4As shown, a rotating shaft 513 is rotatably arranged between the inner walls on both sides of the upper end of the crushing box 1, and a blocking plate 514 for blocking the feed inlet 2 is fixedly arranged on the outer surface of the rotating shaft 513, and the push rod 511 is arranged below the blocking plate 514 and contacts the lower surface of the inclined blocking plate 514. Initially, the push rod 511 can be used to tilt and support the blocking plate 514, and when the triangular plate 510 rotates, the blocking plate 514 can be pushed upward through the synchronous movement of the push rod 511, so that the upper surface of the blocking plate 514 fits the lower end surface of the feed inlet 2. The blocking plate 514 is used to block the feed port 2 to stop the feeding of carbon black. As the frame slide 504 continues to move, the push block 507 will move away from the triangular plate 510, and the triangular plate 510 will gradually lose contact with the push block 507. At this time, the thrust on the triangular plate 510 disappears, and the triangular plate 510 will rotate and reset under the torsional elastic force of the torsion spring 509. At this time, the push rod 511 will gradually slide from the uppermost position of the arc groove 512 to the lowermost position, that is, return to the initial position, and the push rod 511 The pushed blocking plate 514 will also lose the thrust of the push rod 511 and reset synchronously, thereby releasing the blockage of the feed port 2, allowing the carbon black to be fed normally, and so on, thereby realizing the opening and closing of the feed port 2, feeding the carbon black intermittently, avoiding excessive carbon black caused by continuous feeding and affecting the crushing movement of the crushing roller 3, reducing the congestion of the crushing roller 3, thereby ensuring that the carbon black can be crushed stably, and the intermittent feeding method can effectively control the amount of carbon black entering the crushing box 1, avoiding excessive feeding at one time and causing congestion of the crushing roller 3. Thereby affecting the crushing efficiency and crushing quality, through intermittent feeding, it can be ensured that the crushing roller 3 can be crushed in the best state every time the material is fed, thereby improving the overall crushing efficiency, and through the coordinated action of the linkage shaft 501, the first driven disk 502, the lever 503, the frame slide 504 and other components, the mechanism can dynamically adjust the opening and closing of the feed port 2 according to the rotation speed and direction of the crushing roller 3. This dynamic adaptability helps to ensure that the feeding speed of carbon black matches the processing capacity of the crushing roller 3, thereby improving the crushing efficiency and reducing congestion.

[0053] The following is the working process of the contact-type rotation speed monitoring dynamic sensing mechanism 6 to monitor the rotation speed of the crushing roller 3 in real time while controlling the opening and closing of the feed port 2: Figure 6 and Figure 7As shown, since the outer surface of the linkage shaft 501 is also fixedly provided with a second driven disk 601, and the outer surface of the second driven disk 601 is annularly and equidistantly provided with extrusion inclined blocks 602 (it should be noted here that the end of the extrusion inclined block 602 facing the second driven disk 601 is set as a rod structure, and the end of the extrusion inclined block 602 away from the second driven disk 601 is set as a block structure, and one side of the block structure is set as an inclined surface, and the design of the inclined surface can facilitate the subsequent extrusion and pushing of the pressurized ball 606), when the crushing roller 3 rotates to drive the linkage shaft 501 to rotate synchronously to realize the opening and closing of the feed port 2, the linkage rotation of the linkage shaft 501 can also drive the second driven disk 601 to rotate synchronously at the front side of the crushing box 1 with the linkage shaft 501 as the axis. At the same time, the second driven disk 601 The rotation of the disk 601 can drive the extrusion inclined block 602 installed on its outer surface to synchronously follow and rotate with the linkage shaft 501 as the axis. Since the front side of the crushing box 1 is located at the right side of the second driven disk 601, an L-shaped fixing frame 603 is provided, and an L-shaped sleeve 604 is provided on the L-shaped fixing frame 603, and T-shaped slide bars 605 are symmetrically penetrated and slidably provided at both ends of the L-shaped sleeve 604, and the pressure ball 606 is installed on one of the T-shaped slide bars 605 facing the second driven disk 601. When the second driven disk 601 rotates and drives the extrusion inclined block 602 to rotate, under the extrusion effect of the inclined surface of the extrusion inclined block 602, the pressure ball 606 can be pushed to move in the direction of the L-shaped sleeve 604, and the T-shaped slide bar 605 at the left end of the L-shaped sleeve 604 is synchronously driven to slide inward and shrink, as shown in FIG. Figure 7As shown, because a return spring 607 is fixedly arranged between the extrusion inclined block 602 and the L-shaped sleeve 604, when the pressurized ball 606 drives the T-shaped slide bar 605 to move and contract inside the L-shaped sleeve 604, the return spring 607 on this side is squeezed synchronously, and at this time, the air between the two T-shaped slide bars 605 inside the L-shaped sleeve 604 will be pushed toward the T-shaped slide bar 605 arranged at the upper right end of the L-shaped sleeve 604, and the T-shaped slide bar 605 is moved away from the L-shaped sleeve 604 (i.e. upward) under the pushing action of the gas, and because the right end of the L-shaped sleeve 604 vertically upwardly penetrates the T-shaped slide bar 605 that is slidably arranged and the return spring 607 is synchronously arranged between the L-shaped sleeve 604, When the crushing roller 3 is in normal operation, the return spring 607 on this side is stretched synchronously, and a mounting plate 609 is fixedly provided on the front side of the crushing box 1 above the right end of the L-shaped sleeve 604, and a warning light 610 is fixedly provided on the mounting plate 609, and contacts 608 are provided on the opposite sides between the mounting plate 609 and the T-shaped slide bar 605 provided below the mounting plate 609. During the normal operation of the crushing roller 3, the contact time between the extrusion inclined block 602 and the compressed ball 606 can be increased through the rotation effect, that is, the contact time between the extrusion inclined block 602 and the compressed ball 606 is increased, so that the compressed ball 606 can be squeezed and pushed in a state close to continuous contact. At this time, the contact gap between the two adjacent extrusion inclined blocks 602 and the compressed ball 606 is not long enough for the return spring 607 to fully rebound. , so that the two contact points 608 can always maintain contact during the crushing process, thereby turning on the warning light 610, and when the operation of the crushing roller 3 is abnormal (that is, the rotation speed of the crushing roller 3 decreases), the contact time of the extrusion inclined block 602 and the pressure ball 606 is synchronously reduced, and the pressure ball 606 cannot be subjected to nearly continuous extrusion. The contact gap between the two adjacent extrusion inclined blocks 602 and the pressure ball 606 is long enough for the reset spring 607 to rebound. Under the elastic force of the reset spring 607, the two contact points 608 lose contact, and finally the warning light 610 flashes. The staff can know whether the speed of the crushing roller 3 decreases by observing the state change of the warning light 610, which is different from directly observing the linkage shaft 50 1. It will be affected by many factors such as visual limitations, observation angles, and light conditions, resulting in inaccurate judgment. The contact-type speed monitoring can more accurately reflect the change in speed through physical contact and electrical signal conversion. When the speed of the crushing roller 3 decreases or is blocked, this change is very rapid and difficult to be captured in time by the naked eye. The contact-type monitoring can sense the speed change in real time and immediately give feedback through the warning light 610, so that the staff can respond quickly. At the same time, in the early stage of the speed decrease of the crushing roller 3, it has not yet reached the level that can be clearly perceived by direct observation. At this time, the contact-type monitoring method can give an early warning signal through the flashing of the warning light 610, so that the staff can take measures in advance to avoid further expansion of the fault, such as Figure 1 and Figure 2 As shown, a transparent cover shell 4 is provided on the front side of the crushing box 1, which can provide real-time protection for the structures included in the dynamic control cycle opening and closing mechanism 5 and the contact-type speed monitoring dynamic sensing mechanism 6. Meanwhile, the transparent design will not cause visual interference to the warning light 610, thereby facilitating observation by the staff.

[0054] Compared with directly setting up a speed sensor, the mechanism adopts a mechanical structure to monitor the speed, which does not need to rely too much on an external power supply or signal source. Therefore, it has higher reliability and can maintain stable working performance even in harsh working environments. Moreover, through the interaction between the extrusion bevel block 602 and the pressed ball 606, and the assistance of the return spring 607, the mechanism can achieve accurate perception and feedback of speed changes, which helps to improve the stability and reliability of the production process.

[0056] The following is the working process of the adaptive dust accumulation trigger reminder mechanism 7 to deposit the dust in the carbon black fed into the feed port 2 and provide a reminder function according to the accumulated dust weight: Figure 2 , Figure 8 as well as Fig. 9As shown, a support block 701 is fixedly provided on the right inner wall of the crushing box 1, and the left side of the support block 701 is set as an inclined surface, and a slide groove 702 is opened on the inclined surface of the support block 701, and a slider 704 is slidably provided in the slide groove 702, and the left side of the slider 704 clamps the receiving collecting plate 706. Through the design of the inclined surface, the collecting plate 706 can be synchronously inclined between the support block 701 and the sealing plate 514. When the sealing plate 514 is tilted to open the feed port 2, the carbon black discharged through the feed port 2 can fall onto the collecting plate 706 through the inclined path of the sealing plate 514, and then finally fall to the center between the two crushing rollers 3 through the inclined path of the collecting plate 706 for centralized crushing. The inclined design can make the carbon black fall more concentratedly and orderly. The carbon black is then transferred to the crushing roller 3 by a buffer, thereby preventing the carbon black from being suddenly fed into the crushing roller 3. The inclined collecting plate 706 can guide the carbon black falling from the feed port 2 to fall to the center between the two crushing rollers 3 along a more concentrated and orderly path. This concentrated guidance avoids the carbon black from being dispersed or accumulated in a position that is not conducive to crushing inside the crushing box 1, thereby improving the crushing efficiency. The collecting plate 706 is evenly provided with filter holes 707 on the side facing the sealing plate 514, and a cavity 708 for dust deposition is provided inside the collecting plate 706. When the carbon black falls to the surface of the collecting plate 706, large particles of carbon black will continue to fall along the inclined path of the collecting plate 706, while small particles of carbon black dust will pass through the filter holes 707 and float. The dust is then dispersed into the cavity 708 opened inside the inclined collecting plate 706 for deposition (it should be noted that the shape of the cavity 708 is affected by the inclination of the collecting plate 706, and its bottom surface is set as an inclined surface so that the dust can naturally settle under the action of gravity), thereby avoiding the generation of a large amount of dust during the carbon black feeding process, which makes the air inside the crushing box 1 turbid, and causes the dust to float to various places in the crushing box 1, thereby interfering with the internal structure of the crushing box 1, and reducing the concentration of suspended dust in the air, which helps to protect the health of the workers. Compared with the existing dust removal technology, the inclined collecting plate 706 design can not only make the carbon black fall onto the crushing roller 3 more concentrated and orderly, avoiding the dispersion or accumulation of carbon black in the crushing box 1, thereby improving the crushing efficiency, but also During the carbon black feeding process, the dust particles contained in the carbon black can be separated, removed and collected. There is no need for external electrical equipment to process the dust. The dust separation and collection are achieved by physical means, thereby saving energy consumption. As time goes by, the amount of dust deposited inside the collecting plate 706 gradually increases. Under the action of gravity, the position of the collecting plate 706 will move downward synchronously (it should be noted here that the downward movement of the collecting plate 706 is always in the carbon black feeding path, so it will not affect the feeding and receiving of the carbon black). At this time, the slider 704 slides in the slide groove 702 synchronously with the movement of the collecting plate 706. Since the elastic telescopic column 705 is fixedly arranged between the slider 704 and the inner bottom wall of the slide groove 702, when the slider 704 moves downward,The elastic telescopic column 705 will be squeezed synchronously, and when the initial collection plate 706 does not start to collect dust, the elastic force of the elastic telescopic column 705 can lift the slider 704 upward, so as to support the collection plate 706. As the amount of dust deposited in the collection plate 706 increases, since the wall of the chute 702 away from the collection plate 706 is provided with a switch 703 electrically connected to the external reminder, the downward movement of the slider 704 will eventually touch the switch 703, thereby turning on the external reminder and reminding the staff of the full load of dust, thereby reducing the tediousness and omissions of manual inspection and reducing the difficulty of cleaning dust.
