Description

Technical Field

[0001] The invention relates to the field of rotary kilns, and more particularly to a rotary kiln large gear ring device which is easy to adjust. Background Art

[0002] A rotary kiln refers to a rotating calcining kiln (commonly known as a rotary kiln), which is similar in appearance to a rotary bed, and is also called a rotary bed kiln. The rotation of the rotary kiln is mainly driven by gears and the large gear ring on the furnace body. The large gear ring of the calcining furnace is basically rigidly connected by lateral bolts.

[0003] When using a rotary kiln to dry certain materials, the temperature inside the furnace body is high. The temperature change will cause radial contraction and expansion of the furnace body, which can easily lead to uneven radial misalignment. Coupled with other factors such as manufacturing, installation, and use, the large ring gear will produce excessive radial runout during operation, so that the vibration range of the ring gear is expanded. Although it will not affect the kiln body at this time, when the ring gear is meshed with the driving gear, the ring gear will continue to hit the driving gear. The impact force is transmitted to the shaft of the driving gear, which can easily cause the shaft to bend, so that the rotation of the driving gear is hindered, and ultimately the large ring gear cannot rotate at a uniform speed.

[0037] Embodiment 1:

[0038] See also Figure 1-8 A rotary kiln large gear ring device that is easy to adjust includes a gear ring 1, gear teeth 2 and a fixing plate 3, wherein the gear teeth 2 are evenly fixedly installed on the outer wall of the gear ring 1, and the fixing plate 3 is evenly fixedly installed on the inner wall of the gear ring 1; a first plug hole 4 is provided on the top wall of the gear teeth 2, a first through hole 5 communicating with the outside is provided on the side wall of the first plug hole 4, an insertion rod 6 is movably inserted in the first plug hole 4, and a first spring 7 is installed between the insertion rod 6 and the first plug hole 4;

[0039] The gear teeth 2 are evenly provided with guide grooves 8 that match the first insertion holes 4 , and the side walls of the guide grooves 8 are provided with second through holes 9 that communicate with the outside world. The gear teeth 2 are provided with an air supply mechanism that matches the guide grooves 8 .

[0040] First, the fixed plate 3 is fixedly connected to the rotary kiln, at which time the small gear ring on the motor is meshed with the gear 2 on the gear ring 1; during the working process, the motor is started, and the small gear ring pushes the gear 2 during the rotation, thereby driving the gear ring 1 to rotate through the gear 2, thereby achieving the function of driving the rotary kiln to rotate.

[0041] In the initial state, the first spring 7 is in a normal state, and the bottom end of the insertion rod 6 is at the top end of the first insertion hole 4; when the rotary kiln drives the gear ring 1 to vibrate, the gear 2 vibrates with the gear ring 1, and the gear 2 hits the small gear ring. During the collision, the insertion rod 6 impacts the small gear ring. Under the action of the reaction force, the insertion rod 6 is subjected to a reverse thrust, so the insertion rod 6 squeezes the first spring 7 and retracts into the first insertion hole 4. During this process, the impact force of the gear 2 on the small gear ring is absorbed by the first spring 7, thereby reducing the impact force on the small gear ring, that is, reducing the impact force on the rotating shaft of the small gear ring, thereby reducing the probability of bending of the rotating shaft.

[0042] In order to prevent the insertion rod 6 from breaking due to shaking, the insertion rod 6 is tightly fitted with the first insertion hole 4. When the insertion rod 6 is retracted into the first insertion hole 4, the insertion rod 6 and the side wall of the first insertion hole 4 rub against each other and generate heat. Under the action of heat exchange, the generated heat is absorbed by the air in the first insertion hole 4, and under the action of the air supply mechanism, the low-temperature air flows along the guide groove 8 and is finally discharged through the second through hole 9. When the air flow flows along the guide groove 8, under the action of heat exchange, the heat of the gear 2 is absorbed by the air flow, which further reduces the temperature of the gear 2 and improves the heat dissipation effect on the gear 2. Effect: When the insertion rod 6 is retracted into the first insertion hole 4, the gas in the first insertion hole 4 is squeezed, so that the gas with higher temperature can be discharged through the first through hole 5. Since the diameter of the first through hole 5 is small, when the insertion rod 6 pressurizes the inside of the first insertion hole 4, the impact force of the gas flowing out of the first through hole 5 is relatively large, so that the hot air flow can be kept away from the gear teeth 2, thereby reducing the temperature of the gear teeth 2, thereby preventing the gear teeth 2 made of metal from expanding due to heat, thereby reducing the degree of wear on the side wall of the first insertion hole 4, ensuring that the first insertion rod 6 can always fit the side wall of the first insertion hole 4, and preventing the insertion rod 6 from breaking.

[0043] Specifically, Figure 4 As shown, the air supply mechanism includes a first mounting groove 10 opened on the side wall of the gear tooth 2, an elastic air bag 11 is fixedly installed in the first mounting groove 10, and an air pipe 12 extending into the guide groove 8 is fixedly installed on the output end of the elastic air bag 11.

[0044] In the initial state, the elastic airbag 11 is in a full state, and the side wall of the elastic airbag 11 is located outside the first mounting groove 10; during operation, the small ring gear meshes with the gear teeth 2 on the ring gear 1, and the small gear squeezes the side wall of the gear teeth 2; since the side wall of the elastic airbag 11 is located outside the first mounting groove 10, when the small ring gear gradually meshes with the gear teeth 2, the small ring gear gradually squeezes the elastic airbag 11, so that the gas in the small ring gear flows along the air pipe 12 to the guide groove 8, thereby playing a role in supplying air to the guide groove 8.

[0045] Even if the gear ring 1 does not vibrate, the elastic airbag 11 still allows gas to flow in the guide groove 8, thereby being able to cool the gear teeth 2 at any time, preventing the gear teeth 2 from expanding due to heat and excessive wear when meshing with the small gear ring, thereby extending the service life of the gear teeth 2.

[0046] Specifically, Figure 3 As shown, an annular groove is formed at the top of the insertion rod 6, and balls 13 are evenly and movably embedded in the annular groove.

[0047] In the normal state, during the meshing transmission process between the gear teeth 2 and the small ring gear, the insertion rod 6 at the top of the gear teeth 2 is out of contact with the small ring gear; when the gear ring 1 drives the gear teeth 2 to shake and hit the small ring gear, the top of the insertion rod 6 contacts the small ring gear and slides along the surface of the tooth groove of the small ring gear. At this time, under the action of the ball 13, the sliding friction between the insertion rod 6 and the tooth groove of the small ring gear is converted into rolling friction between the ball 13 and the annular groove, reducing the friction force on the insertion rod 6, thereby preventing the insertion rod 6 from wear and failure.

[0048] Furthermore, embedding a plurality of balls 13 in the annular groove can reduce the impact force on a single ball 13 during the impact process, thereby preventing the ball 13 from being deformed by the impact and being unable to rotate.

[0049] Specifically, Figure 3 As shown, a third through hole 14 communicating with the insertion hole is formed on the bottom wall of the annular groove.

[0050] When the insertion rod 6 moves down along the first insertion hole 4 due to the reaction force, the gas in the first insertion hole 4 is squeezed. At this time, the gas in the first insertion hole 4 flows along the first through hole 5 and the third through hole 14. The gas in the third through hole 14 blows into the annular groove, and then flows out along the gap between the ball 13 and the annular groove. When the airflow passes through the annular groove, the dust in the annular groove is subjected to impact force, so that the dust in the annular groove can be cleaned up, which plays a role in ensuring that the ball 13 can rotate smoothly; and when the airflow flows along the third through hole 14, the airflow absorbs the heat of the insertion rod 6, thereby reducing the temperature of the insertion rod 6, preventing the insertion rod 6 from expanding due to frictional heat, and playing a role in reducing the degree of wear of the insertion rod 6.

[0051] Specifically, Figure 3 As shown, filter screens 15 are installed in the first through hole 5 and the third through hole 14 .

[0052] The filter 15 can prevent foreign matter from entering the first socket 4, thereby ensuring that the gap between the plug rod 6 and the inner wall of the first socket 4 remains clean, thereby ensuring that the plug rod 6 can move normally; at the same time, it can prevent dust from accumulating in the first socket 4 and causing the plug rod 6 to be unable to retract.

[0053] Specifically, Figure 6 As shown, an annular cavity 16 is provided on the gear ring 1, a slide groove 17 is provided on the top wall of the annular cavity 16, a connecting block 18 is movably embedded in the slide groove 17, a first connecting rope 19 is fixedly installed on the connecting block 18, and a counterweight block 20 is fixedly installed on the bottom end of the first connecting rope 19.

[0054] When the gear ring 1 rotates, under the action of gravity, the connecting block 18 always slides to the bottom end of the slide groove 17, so that the counterweight block 20 is always in a suspended state; during the shaking process of the gear ring 1, under the action of inertia, the counterweight block 20 maintains its original state for a period of time, and then starts to swing. Therefore, the shaking direction of the gear ring 1 is opposite to the swinging direction of the counterweight block 20, which hinders the shaking of the gear ring 1 and reduces the shaking degree of the gear ring 1.

[0055] Specifically, Figure 6 As shown, a second mounting groove 21 is formed on the bottom wall of the slide groove 17 , a sponge 22 is installed in the second mounting groove 21 , and the sponge 22 is soaked with lubricating oil.

[0056] During operation, the connecting block 18 moves along the slide groove 17, and there is sliding friction between the connecting block 18 and the bottom wall of the slide groove 17. Therefore, under the action of friction, both the connecting block 18 and the slide groove 17 are worn, and under the action of the pulling force of the counterweight block 20, there is a large pressure between the connecting block 18 and the bottom wall of the slide groove 17, which further increases the friction and causes the degree of wear to deepen; therefore, by installing a sponge 22 soaked in lubricating oil in the second mounting groove 21, the lubricating oil can be applied to the surface of the connecting block 18 when the connecting block 18 contacts the sponge 22, thereby reducing the friction force on the connecting block 18 and reducing the degree of wear of the connecting block 18, so that there is no need to frequently replace the connecting block 18, saving costs, and at the same time saving downtime for maintenance, ensuring the working efficiency of the rotary kiln.

[0057] And after the connecting block 18 is worn, the height of the counterweight block 20 will be reduced, so that the counterweight block 20 contacts the bottom wall of the annular cavity 16, causing the counterweight block 20 to fail. Therefore, by reducing the wear degree of the connecting block 18, it is ensured that the counterweight block 20 can be used normally.

[0058] Specifically, Figure 6 , Figure 7 As shown, a slot 23 communicating with the annular cavity 16 is provided on the side wall of the gear ring 1 , a baffle 24 is detachably installed in the slot 23 , and a sealing gasket 25 is installed on the edge of the baffle 24 .

[0059] Since the counterweight 20 has a certain weight, which will increase the weight of the gear ring 1, there is no need to install the counterweight 20 when the gear ring 1 is not shaking; when the gear ring 1 shakes, the baffle 24 is taken out, and the annular cavity 16 is exposed to the outside, and the counterweight 20 can be installed at the bottom end of the first connecting rope 19, and the counterweights 20 of different weights can be replaced according to the shaking degree of the gear ring, thereby ensuring that the counterweight 20 can reduce the shaking degree of the gear ring 1; under the action of the sealing gasket 25, external dust can be prevented from entering the annular cavity 16, thereby ensuring that the connecting block 18 can move normally along the slide groove 17.

[0060] Specifically, Figure 8 As shown, a second plug hole 26 is provided on the side wall of the card slot 23, a snap-in 27 is provided on the side wall of the second plug hole 26, a card rod 28 cooperating with the second plug hole 26 is inserted on the baffle 24, two magnetic blocking rods 29 are symmetrically and movably inserted on the card rod 28, the sides of the two blocking rods 29 close to each other are both inclined surfaces, and a driving rod 30 cooperating with the blocking rod 29 is movably inserted on the card rod 28.

[0061] When the locking nut 23 is fully engaged, the two blocking rods 29 are pulled out of the locking nut 23, and the two blocking rods 29 are pulled out of the locking nut 23, so that the two blocking rods 29 are pulled out of the locking nut 23, and the two blocking rods 29 are pulled out of the locking nut 23, so that the two blocking rods 29 are pulled out of the locking nut 23, and the two blocking rods 29 are pulled out of the locking nut 23, so that the two blocking rods 29 are pulled out of the locking nut 23, so that the two blocking rods 29 are pulled out of the locking nut 23, so that the two blocking rods 29 are pulled out of the locking nut 27, so that the baffle 24 can be fixed in the locking nut 23; when the driving rod 30 is fully engaged in the locking nut 28, the two blocking rods 29 are attracted to each other and exert pressure on the driving rod 30, so as to clamp the driving rod 30, thereby preventing the driving rod 30 from falling off, and thus facilitating the removal of the baffle 24 in the whole process.

[0062] Specifically, Figure 1 , Figure 8 As shown, a handle 31 is fixedly installed on the side wall of the baffle 24 , and a second connecting rope 32 is fixedly installed between the handle 31 and the driving rod 30 .

[0063] When the baffle 24 needs to be removed, the staff grips the handle 31 and then pulls the second connecting rope 32 to pull out the drive rod 30, thereby facilitating the removal of the drive rod 30. The baffle 24 can then be removed by pulling the handle 31, thereby facilitating disassembly.

[0064] Working principle: First, the fixed plate 3 is fixedly connected to the rotary kiln, at which time the small gear ring on the motor meshes with the gear 2 on the gear ring 1; during the working process, the motor is started, and the small gear ring pushes the gear 2 during the rotation, thereby driving the gear ring 1 to rotate through the gear 2, thereby achieving the function of driving the rotary kiln to rotate.

[0065] In the initial state, the first spring 7 is in a normal state, and the bottom end of the insertion rod 6 is at the top end of the first insertion hole 4; when the rotary kiln drives the gear ring 1 to vibrate, the gear 2 vibrates with the gear ring 1, and the gear 2 hits the small gear ring. During the collision, the insertion rod 6 impacts the small gear ring. Under the action of the reaction force, the insertion rod 6 is subjected to a reverse thrust, so the insertion rod 6 squeezes the first spring 7 and retracts into the first insertion hole 4. During this process, the impact force of the gear 2 on the small gear ring is absorbed by the first spring 7, thereby reducing the impact force on the small gear ring, that is, reducing the impact force on the rotating shaft of the small gear ring, thereby reducing the probability of bending of the rotating shaft.

[0066] In order to prevent the insertion rod 6 from breaking due to shaking, the insertion rod 6 is tightly fitted with the first insertion hole 4. When the insertion rod 6 is retracted into the first insertion hole 4, the insertion rod 6 and the side wall of the first insertion hole 4 rub against each other and generate heat. Under the action of heat exchange, the generated heat is absorbed by the air in the first insertion hole 4, and under the action of the air supply mechanism, the low-temperature air flows along the guide groove 8 and is finally discharged through the second through hole 9. When the air flow flows along the guide groove 8, under the action of heat exchange, the heat of the gear 2 is absorbed by the air flow, which further reduces the temperature of the gear 2 and improves the heat dissipation effect on the gear 2. Effect: When the insertion rod 6 is retracted into the first insertion hole 4, the gas in the first insertion hole 4 is squeezed, so that the gas with higher temperature can be discharged through the first through hole 5. Since the diameter of the first through hole 5 is small, when the insertion rod 6 pressurizes the inside of the first insertion hole 4, the impact force of the gas flowing out of the first through hole 5 is relatively large, so that the hot air flow can be kept away from the gear teeth 2, thereby reducing the temperature of the gear teeth 2, thereby preventing the gear teeth 2 made of metal from expanding due to heat, thereby reducing the degree of wear on the side wall of the first insertion hole 4, ensuring that the first insertion rod 6 can always fit the side wall of the first insertion hole 4, and preventing the insertion rod 6 from breaking.

[0067] In the initial state, the elastic airbag 11 is in a full state, and the side wall of the elastic airbag 11 is located outside the first mounting groove 10; during operation, the small ring gear meshes with the gear teeth 2 on the ring gear 1, and the small gear squeezes the side wall of the gear teeth 2; since the side wall of the elastic airbag 11 is located outside the first mounting groove 10, when the small ring gear gradually meshes with the gear teeth 2, the small ring gear gradually squeezes the elastic airbag 11, so that the gas in the small ring gear flows along the air pipe 12 to the guide groove 8, thereby playing a role in supplying air to the guide groove 8.

[0068] Even if the gear ring 1 does not vibrate, the elastic airbag 11 still allows gas to flow in the guide groove 8, thereby being able to cool the gear teeth 2 at any time, preventing the gear teeth 2 from expanding due to heat and excessive wear when meshing with the small gear ring, thereby extending the service life of the gear teeth 2.

[0069] In the normal state, during the meshing transmission process between the gear teeth 2 and the small ring gear, the insertion rod 6 at the top of the gear teeth 2 is out of contact with the small ring gear; when the gear ring 1 drives the gear teeth 2 to shake and hit the small ring gear, the top of the insertion rod 6 contacts the small ring gear and slides along the surface of the tooth groove of the small ring gear. At this time, under the action of the ball 13, the sliding friction between the insertion rod 6 and the tooth groove of the small ring gear is converted into rolling friction between the ball 13 and the annular groove, reducing the friction force on the insertion rod 6, thereby preventing the insertion rod 6 from wear and failure.

[0070] Furthermore, embedding a plurality of balls 13 in the annular groove can reduce the impact force on a single ball 13 during the impact process, thereby preventing the ball 13 from being deformed by the impact and being unable to rotate.

[0071] When the insertion rod 6 moves down along the first insertion hole 4 due to the reaction force, the gas in the first insertion hole 4 is squeezed. At this time, the gas in the first insertion hole 4 flows along the first through hole 5 and the third through hole 14. The gas in the third through hole 14 blows into the annular groove, and then flows out along the gap between the ball 13 and the annular groove. When the airflow passes through the annular groove, the dust in the annular groove is subjected to impact force, so that the dust in the annular groove can be cleaned up, which plays a role in ensuring that the ball 13 can rotate smoothly; and when the airflow flows along the third through hole 14, the airflow absorbs the heat of the insertion rod 6, thereby reducing the temperature of the insertion rod 6, preventing the insertion rod 6 from expanding due to frictional heat, and playing a role in reducing the degree of wear of the insertion rod 6.

[0072] The filter 15 can prevent foreign matter from entering the first socket 4, thereby ensuring that the gap between the plug rod 6 and the inner wall of the first socket 4 remains clean, thereby ensuring that the plug rod 6 can move normally; at the same time, it can prevent dust from accumulating in the first socket 4 and causing the plug rod 6 to be unable to retract.

[0073] During operation, the connecting block 18 moves along the chute 17, and there is sliding friction between the connecting block 18 and the bottom wall of the chute 17. Therefore, under the action of friction, the connecting block 18 and the chute 17 are both worn, and under the action of the pulling force of the counterweight block 20, there is a large pressure between the connecting block 18 and the bottom wall of the chute 17, which further increases the friction and causes the degree of wear to deepen; therefore, by installing a sponge 22 soaked in lubricating oil in the second mounting groove 21, the lubricating oil can be applied to the surface of the connecting block 18 when the connecting block 18 contacts the sponge 22, thereby reducing the friction force on the connecting block 18 and reducing the degree of wear of the connecting block 18, so that there is no need to frequently replace the connecting block 18, saving costs, and at the same time saving downtime and maintenance time, ensuring the working efficiency of the rotary kiln; and after the connecting block 18 is worn, the height of the counterweight block 20 will be reduced, so that the counterweight block 20 contacts the bottom wall of the annular cavity 16, causing the counterweight block 20 to fail, so by reducing the degree of wear of the connecting block 18, it plays a role in ensuring that the counterweight block 20 can be used normally.

[0074] When the gear ring 1 rotates, under the action of gravity, the connecting block 18 always slides to the bottom end of the slide groove 17, so that the counterweight block 20 is always in a suspended state; during the shaking process of the gear ring 1, under the action of inertia, the counterweight block 20 maintains its original state for a period of time, and then starts to swing. Therefore, the shaking direction of the gear ring 1 is opposite to the swinging direction of the counterweight block 20, which hinders the shaking of the gear ring 1 and reduces the shaking degree of the gear ring 1.

[0075] Since the counterweight 20 has a certain weight, which will increase the weight of the gear ring 1, there is no need to install the counterweight 20 when the gear ring 1 is not shaking; when the gear ring 1 shakes, the baffle 24 is taken out, and the annular cavity 16 is exposed to the outside, and the counterweight 20 can be installed at the bottom end of the first connecting rope 19, and the counterweights 20 of different weights can be replaced according to the shaking degree of the gear ring, thereby ensuring that the counterweight 20 can reduce the shaking degree of the gear ring 1; under the action of the sealing gasket 25, external dust can be prevented from entering the annular cavity 16, thereby ensuring that the connecting block 18 can move normally along the slide groove 17.

[0076] During the installation process, first pull the drive rod 30 to make the drive rod 30 extend from the card rod 28. At this time, the two mutually attractive magnetic blocking rods 29 are retracted into the card rod 28. Then align the card rod 28 with the second plug hole 26 and push the baffle 24, so that the baffle 24 drives the card rod 28 into the second plug hole 26. When the baffle 24 completely enters the card slot 23, push the drive rod 30. At this time, the drive rod 30 applies a thrust to the inclined surface of the blocking rod 29. When the thrust component in the horizontal direction is greater than the attraction between the two blocking rods 29, the two blocking rods 29 are both extended from the card rod 28, and the extended blocking rod 29 enters the bayonet 23. 7, so that the baffle 24 can be fixed in the slot 23; when the driving rod 30 completely enters the locking rod 28, the two mutually attracted baffle rods 29 exert pressure on the driving rod 30, thereby clamping the driving rod 30, thereby preventing the driving rod 30 from falling, and thus facilitating the removal of the baffle 24 during the entire process; when the baffle 24 needs to be removed, the staff member holds the handle 31 tightly and then pulls the second connecting rope 32, so that the driving rod 30 can be pulled out, thereby facilitating the removal of the driving rod 30, and then the baffle 24 can be taken out by pulling the handle 31, thereby facilitating disassembly.
