Description

Technical Field

[0001] The invention belongs to the technical field of covering rubber preparation, and specifically relates to a preparation device and process for a resistant conveyor belt covering rubber. Background Art

[0002] Resistant conveyor belts are designed to meet specific working environments and material conveying requirements. They use special rubber formulas, skeleton materials and manufacturing processes to operate stably in high temperature, oily, corrosive or harsh environments without premature aging, cracking or performance degradation.

[0003] Covering rubber is a rubber material applied to the surface of the conveyor belt. By adding covering rubber to the conveyor belt, the durability of the conveyor belt can be improved. The material of the covering rubber is usually rubber. Different rubber formulas and additives can be selected according to the specific use environment and needs to enhance its heat resistance, wear resistance, impact resistance, etc.

[0004] For example, the disclosed patent: CN118047983A discloses a heat-resistant rubber conveyor belt covering rubber and a preparation method thereof, which comprises the following steps: adding composite rubber, hydrogenated nitrile rubber, stearic acid, high heat-resistant composite filler and silane coupling agent Si-69 in an internal mixer in sequence, mixing at a temperature of 125 to 135°C for 25 to 40 minutes, discharging to obtain a mixed rubber, and then naturally cooling the mixed rubber to room temperature; adding vulcanizing agent DCP, co-vulcanizing agent TAI C, nano zinc oxide, antioxidant RD and accelerator DM in sequence in the internal mixer, mixing at 95 to 105°C for 15 to 25 minutes, discharging and transferring to an open mixer, re-mixing at 78 to 83°C for 3 to 7 minutes, and calendering into a sheet through a calender to obtain a heat-resistant high temperature rubber conveyor belt covering rubber.

[0005] Since raw materials such as composite rubber and hydrogenated nitrile rubber may contain a certain amount of powdery components, these components may generate dust due to friction, shearing and other effects during the mixing process of the internal mixer. After long-term use of the internal mixer, its seals, rotors, mixing chambers and other components may lose their original sealing properties due to wear and aging, resulting in leakage of dust and exhaust gas. These dusts and exhaust gases may contain volatile organic compounds (VOCs), particulate matter and other harmful substances. These substances are transmitted through the air and can easily cause air pollution. In addition, certain components in dust and exhaust gases may irritate the skin or cause allergic reactions, resulting in symptoms such as skin redness, swelling, and itching.

At this time, once the magnetic ring that adsorbs the magnetic block rotates, the magnetic block will pull the connecting rope to move. At this time, the connecting rope will pull one end of the hammer rod to move downward, allowing the torsion spring to accumulate force until the top block on the magnetic ring separates the magnetic block from the magnetic ring. At this time, the torsion spring will release elastic potential energy to cause the hammer rod to hammer on the first filter frame or the second filter frame, thereby reducing the risk of the mesh being blocked by dust through vibration, thereby ensuring the filtering effect.

[0045] A notch is provided at the bottom end of the partition plate 13 , through which the first chamber 14 and the second chamber 15 are connected. By opening the cover plate 8 , the first filter frame 9 or the second filter frame 11 in the first chamber 14 or the second chamber 15 can be taken out and replaced.

[0046] A treatment box 5 is provided on one side of the air collecting box 4, a fan 43 is provided inside the treatment box 5, an activated carbon plate 6 is provided on the top of the treatment box 5, the input end of the fan 43 extends to the inside of the air collecting box 4, the air collecting box 4 is connected with the air ring 2 through a connecting pipe 7, one end of the connecting pipe 7 extends to the inside of the partition plate 13, a through opening 42 is opened on the partition plate 13, the through opening 42 is connected with the first chamber 14 and the second chamber 15, a diverter ball 16 is rotatably installed inside the through opening 42, a transfer groove 17 is opened inside the diverter ball 16, and the transfer groove 17 is set to be L-shaped.

[0047] One end of the L-shaped adapter groove 17 is connected to the connecting pipe 7. When the other end is connected to the first chamber 14, the dust adsorbed by negative pressure will enter the first chamber 14 and be filtered by the first filter frame 9. When the other end of the L-shaped adapter groove 17 is connected to the second chamber 15, the adsorbed dust will enter the second chamber 15 through the opening 42 and then be filtered by the second filter frame 11.

[0048] The switching of the L-shaped switching groove 17 is controlled by the rotation of the diverter ball 16 , and the switching can be completed by controlling the diverter ball 16 to rotate 180 degrees.

[0049] By starting the fan 43 , the interior of the air collecting box 4 can be in a negative pressure state, and at this time, the dust generated by the banburying can be absorbed into the interior of the air collecting box 4 through the air port 3 on the air ring 2 .

[0050] A vibration assembly is disposed inside the first chamber 14 and the second chamber 15 to control the vibration of the first filter frame 9 and the second filter frame 11;

[0051] The vibration component is provided to vibrate the first filter frame 9 and the second filter frame 11, thereby reducing the situation where dust blocks the mesh holes and ensuring the flow rate of air.

[0052] As a preferred embodiment of the present invention, the bottom end of the diverter ball 16 is fixedly connected to a rotating rod 18, and the bottom end of the rotating rod 18 is fixedly installed with a first gear 19. The side of the first gear 19 close to the first chamber 14 is meshed with a second gear 22, and the side of the first gear 19 close to the second chamber 15 is meshed with a third gear 25.

[0053] When the third gear 25 rotates, the first gear 19 will drive the rotating rod 18 to rotate, so that the diverter ball 16 rotates. When the second gear 22 rotates, it will also drive the first gear 19 to rotate, and can also control the diverter ball 16 to rotate.

[0054] As a preferred embodiment of the present invention, the first transmission rod 21 is rotatably installed inside the second gear 22, the first ratchet 27 is fixedly installed on the outer wall of the first transmission rod 21, and the first ratchet rod 28 for blocking the rotation of the first ratchet 27 is elastically installed inside the second gear 22.

[0055] The first ratchet rod 28 is installed inside the second gear 22 through a torsion spring. Through the arrangement of the first ratchet 27 and the first ratchet rod 28, the counterclockwise rotation of the first transmission rod 21 can be blocked. Therefore, when the first transmission rod 21 rotates counterclockwise, the first ratchet 27 will be driven to rotate counterclockwise through the first ratchet rod 28, and at this time, the first gear 19 and the diverter ball 16 can be driven to rotate. When the first transmission rod 21 rotates clockwise, it will not be blocked by the first ratchet rod 28, and at this time, the first transmission rod 21 will not drive the second gear 22 to rotate clockwise.

[0056] As a preferred embodiment of the present invention, the second transmission rod 24 is rotatably mounted inside the third gear 25 , the second ratchet 33 is fixedly mounted on the outer wall of the second transmission rod 24 , and the second ratchet rod 34 for blocking the second ratchet 33 is elastically mounted inside the third gear 25 .

[0057] The second ratchet rod 34 is installed inside the third gear 25 through a torsion spring. Through the arrangement of the second ratchet 33 and the second ratchet rod 34, the clockwise rotation of the second transmission rod 24 can be blocked. Therefore, when the second transmission rod 24 rotates counterclockwise, the second ratchet 33 will be driven to rotate clockwise through the second ratchet rod 34, and at this time, the first gear 19 and the diverter ball 16 can be driven to rotate. When the second transmission rod 24 rotates counterclockwise, it will not be blocked by the second ratchet rod 34, and at this time, the second transmission rod 24 will not drive the third gear 25 to rotate counterclockwise.

[0058] As a preferred embodiment of the present invention, a first slider 20 is slidably mounted on the outer wall of the first transmission rod 21, a first spiral groove 30 is formed on the outer wall of the first transmission rod 21, a first guide block 29 is fixedly mounted on the inner wall of the first slider 20, one end of the first guide block 29 extends to the inside of the first spiral groove 30, and a first pressing spring is arranged between the first slider 20 and the second gear 22;

[0059] A first support frame 10 is fixedly installed on the top of the first filter frame 9, and the first support frame 10 is slidably installed inside the first chamber 14. A first abutment plate 26 is fixedly installed on the top of the first slider 20, and one end of the first abutment plate 26 extends to the bottom end of the first support frame 10 and fits therewith.

[0060] The first pressing spring can ensure that the first sliding block 20 always maintains a tendency to separate from the second gear 22 .

[0061] When the first support frame 10 drives the first filter frame 9 to slide downward inside the first chamber 14, the first slider 20 will drive the first guide block 29 to slide downward along the inside of the first spiral groove 30, driving the first transmission rod 21 to rotate counterclockwise, and at the same time driving the second gear 22 to rotate counterclockwise. When the first slider 20 slides to the end of the trajectory, the first gear 19 just drives the rotating rod 18 and the diverter ball 16 to rotate 180 degrees to realize the switching of the adapter groove 17, and when the first slider 20 drives the first transmission rod 21 to rotate, it will control the adapter groove 17 on the diverter ball 16 to connect the second chamber 15 with the connecting pipe 7. At this time, the dust will also be filtered through the second filter frame 11.

[0062] As a preferred embodiment of the present invention, a second spiral groove 32 is formed on the outer wall of the second transmission rod 24, a second slider 23 is slidably mounted on the outer wall of the second transmission rod 24, a second guide block 31 is fixedly mounted on the inner wall of the second slider 23, one end of the second guide block 31 extends to the inside of the second spiral groove 32, and a second pressure spring is arranged between the second slider 23 and the third gear 25;

[0063] A second support frame 12 is fixedly mounted on the top of the second filter frame 11, and the second support frame 12 is slidably mounted inside the second chamber 15. A second abutment plate 44 is fixedly mounted on the top of the second slider 23, and one end of the second abutment plate 44 extends to and fits the bottom of the second support frame 12.

[0064] The second pressing spring can ensure that the second sliding block 23 always maintains a tendency to separate from the third gear 25 .

[0065] When the second support frame 12 drives the second filter frame 11 to slide downward inside the second chamber 15, the second slider 23 will drive the second guide block 31 to slide downward along the inside of the second spiral groove 32, driving the second transmission rod 24 to rotate clockwise, and at the same time driving the third gear 25 to rotate clockwise. When the second slider 23 slides to the end of the trajectory, the first gear 19 just drives the rotating rod 18 and the diverter ball 16 to rotate 180 degrees to realize the switching of the adapter groove 17, and when the second slider 23 drives the second transmission rod 24 to rotate, it will control the adapter groove 17 on the diverter ball 16 to connect the first chamber 14 with the connecting pipe 7. At this time, the dust will also be filtered through the first filter frame 9.

[0066] By controlling the rotation of the diverter ball 16, the adapter slot 17 is switched to communicate with the first chamber 14 and the second chamber 15. When there is a lot of dust inside the first filter frame 9 or the second filter frame 11, it can be switched in time, which can effectively increase the working time of dust filtering.

[0067] As a preferred embodiment of the present invention, a blocking frame 35 is fixedly mounted on the inner walls of the first chamber 14 and the second chamber 15 , and the outer walls of the first filter frame 9 and the second filter frame 11 are in contact with the inner walls of the blocking frame 35 .

[0068] One end of the first filter frame 9 and the second filter frame 11 both extend out of the blocking frame 35. When the first filter frame 9 filters dust, if the dust accumulation height in the first filter frame 9 is higher than the height of the blocking frame 35, the fan 43 continues to use negative pressure. Under the condition of limited wind flux, the first filter frame 9 will be sucked to slide downward in the first chamber 14, so that the first slider 20 drives the first guide block 29 to slide downward along the inside of the first spiral groove 30, driving the first transmission rod 21 to rotate counterclockwise, and driving the second gear 22 to rotate counterclockwise at the same time. When the first slider 20 slides to the end of the trajectory, the first gear 19 just drives the rotating rod 18 and the diverter ball 16 to rotate 180 degrees, so that the adapter groove 17 is connected with the second chamber 15. At this time, the dust will be filtered through the second filter frame 11. Under the reset of the first top pressure spring, the first filter frame 9 will be reset, and it can be taken out and processed by opening the cover plate 8, thereby effectively improving the filtering effect.

[0069] If the dust accumulates to a certain height in the second filter frame 11 and is higher than the height of the blocking frame 35, when the wind flux is limited, the second filter frame 11 will be sucked to slide downward in the second chamber 15, so that the second slider 23 drives the second guide block 31 to slide downward along the inside of the second spiral groove 32, driving the second transmission rod 24 to rotate clockwise, and at the same time drives the third gear 25 to rotate clockwise, so that the rotating rod 18 drives the diverter ball 16 to rotate 180 degrees, so that the adapter groove 17 is connected with the first chamber 14. At this time, the dust will continue to be filtered through the first filter frame 9. Under the reset of the second top pressure spring, the second filter frame 11 will be reset, and it can be taken out and processed by opening the cover plate 8, which is convenient for next use.

[0070] As a preferred embodiment of the present invention, the vibration assembly includes a mounting frame 36, a magnetic ring 38, a hammer rod 41, a magnetic block 39 and a connecting rope 40. The mounting frame 36 is fixedly mounted on the inner wall of the first chamber 14 and the second chamber 15, the magnetic ring 38 is fixedly mounted on the top of the mounting frame 36, the hammer rod 41 is elastically mounted on the top of the blocking frame 35, the magnetic block 39 is fixedly connected to the hammer rod 41 through the connecting rope 40, and the magnetic ring 38 and the magnetic block 39 attract each other;

[0071] A top block 45 for pushing the magnetic block 39 is fixedly mounted on the top of the magnetic ring 38 , and an impeller 37 is rotatably mounted inside the mounting frame 36 , and the impeller 37 is fixedly connected to the magnetic ring 38 via a connecting shaft.

[0072] The hammer rod 41 is installed on the top of the blocking frame 35 through a torsion spring. By pulling the connecting rope 40, the hammer rod 41 can be driven to flip upward. At the same time, the torsion spring will also store elastic potential energy. Loosening the connecting rope 40 will release the elastic potential energy. At this time, the hammer rod 41 will hammer the outer wall of the first filter frame 9 or the second filter frame 11.

[0073] When the fan 43 is started and the wind is transported toward the treatment box 5, the impeller 37 will be driven to rotate, and at the same time, the magnetic ring 38 will be driven to rotate on the mounting frame 36 under the action of the connecting shaft. At this time, once the magnetic ring 38 that adsorbs the magnetic block 39 rotates, the magnetic block 39 will pull the connecting rope 40 to move. At this time, the connecting rope 40 will pull one end of the hammer rod 41 to move downward, so that the torsion spring will accumulate force until the top block 45 on the magnetic ring 38 separates the magnetic block 39 from the magnetic ring 38. At this time, the torsion spring will release elastic potential energy to make the hammer rod 41 hammer on the first filter frame 9 or the second filter frame 11, and reduce the risk of the mesh being blocked by dust through vibration, thereby ensuring the filtering effect.

[0074] like Fig. 9 As shown, a process for preparing a resistant conveyor belt covering rubber, the process adopts the above-mentioned device for preparing a resistant conveyor belt covering rubber, and comprises the following steps:

[0075] S1: adding composite rubber, hydrogenated nitrile rubber, stearic acid, high heat-resistant composite filler and silane coupling agent Si-69 in an internal mixer 1 in sequence, mixing at a temperature of 120 to 130° C. for 30 to 40 minutes, and obtaining a mixed rubber after discharging;

[0076] S2: The dust produced during mixing is sucked into the air collecting box 4 by the fan 43, and the dust is filtered by the first filter frame 9 and the second filter frame 11, and then passed into the treatment box 5, and the odor is purified by the activated carbon plate 6;

[0077] S3: The mixed rubber is naturally cooled to room temperature, and vulcanizing agent DCP, co-vulcanizing agent TAIC, nano zinc oxide, antioxidant RD and accelerator DM are added to internal mixer 1 in sequence, mixed at 90-110° C. for 17-23 min, transferred to an open mixer after discharge, re-mixed at 80-85° C. for 4-8 min, and calendered into a rubber sheet by a calender to prepare a heat-resistant conveyor belt covering rubber.

[0078] Working principle: When one end of the first filter frame 9 and the second filter frame 11 both extend out of the blocking frame 35, when the first filter frame 9 filters dust, if the dust accumulation height in the first filter frame 9 is higher than the height of the blocking frame 35, the fan 43 continues to use negative pressure at this time. Under the condition of limited wind flux, the first filter frame 9 will be sucked to slide downward in the first chamber 14, so that the first slider 20 drives the first guide block 29 to slide downward along the inside of the first spiral groove 30, driving the first transmission rod 21 to rotate counterclockwise, and driving the second gear 22 to rotate counterclockwise at the same time. When the first slider 20 slides to the end of the trajectory, the first gear 19 just drives the rotating rod 18 and the diverter ball 16 to rotate 180 degrees, so that the adapter groove 17 is connected with the second chamber 15. At this time, the dust will be filtered through the second filter frame 11. Under the reset of the first top pressure spring, the first filter frame 9 will be reset, and it can be taken out and processed by opening the cover plate 8, thereby effectively improving the filtering effect.

[0079] When the dust accumulates to a certain height in the second filter frame 11 and is higher than the height of the blocking frame 35, under the condition of limited wind flux, the second filter frame 11 will be sucked to slide downward in the second chamber 15, so that the second slider 23 drives the second guide block 31 to slide downward along the inside of the second spiral groove 32, driving the second transmission rod 24 to rotate clockwise, and at the same time drives the third gear 25 to rotate clockwise, so that the rotating rod 18 drives the diverter ball 16 to rotate 180 degrees, so that the adapter groove 17 is connected with the first chamber 14. At this time, the dust will continue to be filtered through the first filter frame 9. Under the reset of the second top pressure spring, the second filter frame 11 will be reset, and it can be taken out and processed by opening the cover plate 8 for easy use next time. By controlling the rotation of the diverter ball 16, the adapter groove 17 is switched to be connected with the first chamber 14 and the second chamber 15, and the first filter frame 9 or the second filter frame 11 can be flexibly switched to ensure the filtering effect.

[0080] By starting the fan 43 and conveying the wind toward the treatment box 5, the impeller 37 will be driven to rotate, and at the same time, the magnetic ring 38 will be driven to rotate on the mounting frame 36 under the action of the connecting shaft. At this time, once the magnetic ring 38 that adsorbs the magnetic block 39 rotates, the magnetic block 39 will pull the connecting rope 40 to move. At this time, the connecting rope 40 will pull one end of the hammer rod 41 to move downward, so that the torsion spring will accumulate force until the top block 45 on the magnetic ring 38 separates the magnetic block 39 from the magnetic ring 38. At this time, the torsion spring will release elastic potential energy to make the hammer rod 41 hammer on the first filter frame 9 or the second filter frame 11, and reduce the risk of the mesh being blocked by dust through vibration, thereby ensuring the filtering effect.
