Description

Technical Field

[0001] This invention relates to the field of material drying, specifically to a rotary kiln material drying device. Background Technology

[0002] A rotary kiln material drying device is a device that uses an inclined rotating cylinder in conjunction with hot air. The internal lifting structure throws and shakes the material, thereby achieving large-area contact between the material and the hot air. The hot air removes the moisture from the material, thus completing the drying process. The dried material flows out at an angle along the cylinder of the device. It is suitable for drying materials such as minerals, medicinal materials, and waste residue.

[0003] Currently, rotary kiln material drying equipment typically involves placing the material directly inside the equipment and having the lifting structure scatter it for drying. However, if the material contains a lot of moisture, it will adhere tightly to the surface, making it difficult for the material to spread evenly when scattered by the lifting structure. This results in insufficient contact between the material and the hot air, leading to incomplete evaporation of moisture and a significant reduction in drying efficiency. Furthermore, the equipment requires prolonged hot air blowing, resulting in energy waste. Therefore, improvements are needed. Summary of the Invention

[0015] (III) Beneficial Effects This invention provides a rotary kiln material drying device. It has the following beneficial effects: By setting up a structure with the cooperation of shaking plate, contact plate and rotating ring, when the rotating ring rotates, it will drive the shaking plate to rotate at the same time to dig up the material. When the contact plate contacts and separates from the contact strip, the contact plate will drive the shaking plate to shake within a certain distance with the help of spring. This makes the material more violently thrown by the shaking plate, allowing the material to come into fuller contact with the hot air, improving the drying efficiency, and making fuller use of the hot air to save energy.

[0016] By setting up a structure that works in conjunction with the rollers, dispersing bars, and rotating columns, the rotating columns are driven to rotate along the rollers when the rollers rotate. The rotating columns also rotate on their own axis, causing the dispersing bars to break up the aggregated material. This further improves the contact between the material and the hot air, resulting in better drying of the material.

[0017] By setting up a combination of structures such as contact grooves, rollers, and perforated plates, the water vapor from the dried material enters the interior of the contact groove through the holes in the perforated plate. This increases the contact area between the contact groove and the water vapor and hot air, thereby absorbing the residual heat and transferring it to the inner wall of the roller. This significantly increases the temperature inside the roller, enhancing the drying effect on the material and further utilizing the heat to save energy. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figure 1-13 As shown, this embodiment of the invention provides a rotary kiln material drying device, including a drum 1; a collar 3 is fixedly sleeved on the outer side of the drum 1; a drive gear ring 4 is fixedly connected to the outer surface of the middle end of the drum 1; a support mechanism 2 is provided below the drum 1; the support mechanism 2 cooperates with the drive gear ring 4 and the collar 3; a placement shell 8 is rotatably connected to the outer side of one end of the drum 1; a support frame 10 is fixedly connected to the lower end of the placement shell 8; a dispersing mechanism 5 is provided inside the placement shell 8, and the dispersing mechanism 5 cooperates with the inner side of the drum 1; a lifting mechanism 6 is provided inside the drum 1, and the lifting mechanism 6 cooperates with the placement shell 8; a heat absorption mechanism 9 is provided inside the drum 1 near the lifting mechanism 6; and a purification mechanism 7 is provided inside the drum 1 at the end away from the placement shell 8.

[0022] In the above process, the rotation of the drum 1 drives the dispersing mechanism 5 and the lifting mechanism 6 to rotate simultaneously. The dispersing mechanism 5 disperses the aggregated material, and the lifting mechanism 6 further lifts it up violently, allowing the material to come into more full contact with the hot air and improving the drying effect.

[0023] The support mechanism 2 includes a base 201, a mounting plate 202, a support seat 203, a rotating wheel 204, and a spur gear 205. The mounting plate 202 is fixed to the top surfaces of both ends of the base 201. The support seat 203 is fixed to the upper surfaces of both ends of the mounting plate 202. The rotating wheel 204 is rotatably connected to the inner side of the support seat 203, and the rotating wheel 204 located on the same mounting plate 202 is in contact with the collar 3. A motor is fixedly installed on one side of the upper surface of the base 201. The spur gear 205 is fixed to the output end of the motor, and the spur gear 205 is meshed with the drive gear ring 4. The upper end of the support frame 10 is higher than the base 201.

[0024] In the above, by setting the support frame 10 higher than the base 201, the collar 3 and drive gear ring 4 and other parts are tilted, allowing the material to flow along the tilt.

[0025] The disintegration mechanism 5 includes a connecting column 501, a connecting bar 502, a rotating column 503, a disintegration bar 504, a rotating gear 505, an internal gear ring 506, a limiting plate 507, and a mounting groove 508. The mounting groove 508 is located on the inner side of the placement shell 8 at the end away from the roller 1. The limiting plate 507 is rotatably connected to the inner surface of the placement shell 8 near the mounting groove 508. The connecting column 501 is located at the center of the end of the roller 1 near the placement shell 8. The connecting bar 502 is fixed to the outer surface of the connecting column 501, and the end of the connecting bar 502 away from the connecting column 501 is fixed to the inner side of the roller 1. The rotating column 503 is rotatably connected to the inside of the connecting bar 502. The end of the rotating column 503 away from the connecting bar 502 passes through the limiting plate 507 and extends into the inside of the mounting groove 508.

[0026] In the above, by setting the mutual cooperation between the limiting plate 507 and the rotating column 503, the limiting plate 507 limits the rotating column 503, making the rotation of the rotating column 503 more stable.

[0027] The self-rotating gear 505 is fixedly connected to the end of the rotating column 503 away from the connecting bar 502; the internal gear ring 506 is fixedly connected to the inner surface of the mounting groove 508, and the internal gear ring 506 is meshed with the self-rotating gear 505; the dispersing bar 504 is fixedly connected to the outer surface of the rotating column 503, and the dispersing bar 504 is set in several pieces and evenly distributed in a ring at equal angles.

[0028] In the above, by setting the internal gear ring 506 and the rotating gear 505 to cooperate with each other, when the rotating column 503 drives the rotating gear 505 to rotate, the rotating gear 505 will drive the rotating column 503 to rotate under the cooperation of the internal gear ring 506.

[0029] The lifting mechanism 6 includes a first bevel gear 601, a second bevel gear 602, a connecting bevel gear 603, a connecting sleeve 604, a rotating ring 605, a rocking plate 606, a contact plate 607, a contact strip 608, and a setting groove 609. The setting groove 609 is located on the inner side of the housing 8 near the roller 1. The first bevel gear 601 is located inside the setting groove 609. The first bevel gear 601 is fixedly sleeved on the outer side of one end of the roller 1. The second bevel gear 602 is rotatably sleeved on the outer side of the roller 1. The connecting bevel gear 603 is located on the side where the first bevel gear 601 and the second bevel gear 602 are close to each other, and both sides of the connecting bevel gear 603 are respectively meshed with the first bevel gear 601 and the second bevel gear 602. A cylinder is fixedly connected to the inner center of the connecting bevel gear 603, and the lower end of the cylinder is fixedly connected to the bottom surface of the setting groove 609.

[0030] In the above, by setting the first bevel gear 601, the second bevel gear 602 and the connecting bevel gear 603 to cooperate with each other, when the first bevel gear 601 rotates, it will drive the second bevel gear 602 to rotate in the opposite direction through the connecting bevel gear 603 to drive the rocking plate 606.

[0031] The connecting sleeve 604 is rotatably fitted inside the drum 1, and the connecting sleeve 604 is fixedly connected to the side of the second bevel gear 602 away from the first bevel gear 601; the rotating ring 605 is rotatably connected inside the drum 1, and the connecting sleeve 604 is fixedly connected to the outer surface of the rotating ring 605; the rocking plate 606 is rotatably connected inside the rotating ring 605, and the rocking plate 606 is configured as several and evenly distributed in a ring at equal angles; a contact plate 607 is provided on the side of the drum 1 near the rocking plate 606, and the contact plate 607 corresponds to the rocking plate 606; a spring is provided on the side of the rocking plate 606 and the contact plate 607 that are close to each other, and the two ends of the spring are fixedly connected to the side of the rocking plate 606 and the contact plate 607 that are close to each other, respectively; a contact strip 608 is fixedly connected to the side of the inner cavity of the drum 1 away from the rotating ring 605, and the contact strip 608 is configured as several and evenly distributed.

[0032] In the above, by setting up the interaction between the contact strip 608 and the contact plate 607, when the rotating ring 605 drives the contact plate 607 to rotate, the contact strip 608 will rotate in the opposite direction to the contact plate 607, so that the contact strip 608 contacts the contact plate 607. With the help of the spring, the contact plate 607 will drive the rocking plate 606 to swing back and forth, so that the rocking plate 606 will throw the material more violently.

[0033] The heat absorption mechanism 9 includes a contact groove 901 and a perforated plate 902; the contact groove 901 is opened inside the drum 1 and is connected to the inner cavity of the drum 1; the perforated plate 902 is fixed to the inner side of the connection between the contact groove 901 and the drum 1.

[0034] In the above, by setting a perforated plate 902, when the material approaches the contact groove 901, the perforated plate 902 will block the material, ensuring that water vapor and hot air can enter the contact groove 901 while preventing the material from entering, thus reducing the problem of blockage in the contact groove 901.

[0035] A lifting plate 12 is fixedly connected to the inner wall of the contact groove 901 near the roller 1; the lifting plate 12 is configured as a plurality of plates and is evenly distributed on the inner side of the roller 1.

[0036] In the above, by setting the positional relationship between the contact groove 901 and the lifting plate 12, the material flow speed will be slowed down when the material comes into contact with the lifting plate 12. At this time, the inner wall of the drum 1, which is further heated by the residual heat of the contact groove 901, will come into contact with the material, thereby improving the drying effect of the material. Due to the improved drying efficiency, the time for the hot air blower to blow out hot air is greatly reduced, further saving energy.

[0037] The purification mechanism 7 includes a rotating ring 701, a threaded sleeve 702, and an activated carbon plate 703. The activated carbon plate 703 is disposed inside the end of the roller 1 away from the housing 8. The threaded sleeve 702 is fixedly connected to the end of the activated carbon plate 703 away from the housing 8, and the threaded sleeve 702 is threadedly connected to the inside of the roller 1. The rotating ring 701 is fixedly connected to the end of the threaded sleeve 702 away from the activated carbon plate 703. Several evenly distributed through holes are opened on the inner surface of the roller 1 near the activated carbon plate 703, and the activated carbon plate 703 is connected to the inner cavity of the roller 1 through the through holes.

[0038] In the above, by setting the activated carbon plate 703 and the through hole to be connected, when the material is drying, the polluting gas released can come into contact with the activated carbon plate 703 through the through hole, so that the activated carbon plate 703 can filter the gas.

[0039] A support rod 13 is fixedly connected to the inner cavity of the end of the roller 1 away from the placement shell 8, and the support rod 13 is set in several and evenly distributed; a funnel 11 is fixedly connected to the upper end of the placement shell 8, and the funnel 11 is connected to the inner cavity of the placement shell 8.

[0040] As described above, the support rod 13 can support the roller 1, reduce the deformation of the roller 1, extend the life of the roller 1, and make it more stable during use.

[0041] Working principle: When using, first take out the hot air blower and install it with the device, aligning the air outlet of the hot air blower with the round hole of the housing 8. Then turn on the hot air blower, causing the impeller inside the hot air blower to rotate and generate negative pressure, drawing outside air into the machine body from the air inlet and delivering it to the air outlet. During the flow, the delivered air will come into contact with the heating element heating wire / PTC heating plate and be heated. Then the heated air will enter the inner side of the housing 8 and the roller 1 in sequence and be output from the end of the roller 1 near the support rod 13. When the internal temperature of drum 1 is sufficiently heated, start the motor to drive the spur gear 205 to rotate. The rotation of the spur gear 205 will also drive the drive gear ring 4 to rotate. Since the drive gear ring 4 is fixed to drum 1, it will also drive drum 1 to rotate simultaneously. When drum 1 rotates, it will drive the connecting bar 502 and the connecting column 501 to rotate. At this time, the rotating column 503 inside the connecting bar 502 will rotate around the connecting column 501 as its center, driven by the connecting bar 502. The rotating connecting column 501 will then drive the self-rotating gear 505 to rotate simultaneously. Since the self-rotating gear 505 meshes with the internal gear ring 506, the rotating column 503 will rotate during rotation. At this time, the material to be dried is poured into the funnel 11, allowing the material to enter the interior of the placement shell 8 along the funnel 11. At this time, the material will come into contact with the rotating column 503 and the dispersing bar 504, allowing the dispersing bar 504 to disperse the tightly attached material, allowing the material to come into more full contact with the hot air. Then, the dispersed material enters the interior of the drum 1 under the blowing of the hot air and the tilt of the placement shell 8, allowing the rotating drum 1 to drive the material to flow along the tilt. While the drum 1 rotates, it also drives the first bevel gear 601 to rotate. With the cooperation of the first bevel gear 601 and the connecting bevel gear 603, the connecting bevel gear 603 drives the second bevel gear 602 to rotate in the opposite direction. The rotating second bevel gear 602 drives the connecting sleeve 604, which is fixed on one side, to rotate in the opposite direction to the rotation of the drum 1. The rotating connecting sleeve 604 drives the rotating ring 605 to rotate simultaneously. At the same time, the rocking plate 606 inside the rotating ring 605 rotates and moves around the rotating ring 605 as its center, driven by the rotating ring 605. As the rocking plate 606 rotates, it scoops up the material, and when the rocking plate 606 is at a high position, it spills the material. Simultaneously, the rocking plate 606 cooperates with the contact plate 607 through a spring. During the movement of the rocking plate 606, it drives the spring and the contact plate 607 to move simultaneously. During the movement of the contact plate 607, it contacts the contact strip... When contact strip 608 comes into contact with the contact plate 608, the contact plate 608 will encounter resistance and tilt due to the spring driving the rocking plate 606. During the tilting process, one side of the rocking plate 606 will contact the inner side of the rotating ring 605, thereby blocking and limiting the tilting of the rocking plate 606. At this time, the contact plate 607 is in a slightly tilted state. Under the obstruction of the rocking plate 606, the contact plate 607 can only slide along the surface of the contact strip 608, thereby compressing the spring. When the contact plate 607 separates from the contact strip 608, the contact plate 607 will return to its original position under the push of the spring. This process is repeated. With the periodic contact between the contact plate 607 and the contact strip 608, the rocking plate 606 will swing back and forth, making the rocking plate 606 throw the material more vigorously, while further dispersing the fine material, making the material contact with the hot air more even, increasing the contact area, and further improving the drying effect. Simultaneously, water vapor is generated during the drying process. This water vapor accumulates above the inner cavity of drum 1 and moves towards the outlet end of drum 1. During this movement, the water vapor comes into contact with the perforated plate 902. At this time, the water vapor and some hot air enter the interior of the contact groove 901 through the holes on the surface of the perforated plate 902 and flow out from the opening at the end of the contact groove 901 near the support rod 13. During the movement of the water vapor and hot air, the residual heat inside is absorbed by the inner wall of the contact groove 901, further heating the inner surface of drum 1. When the material moves inside the drum 1 to the side near the contact groove 901, the lifting plate 12 lifts the material and it comes into contact with the drum 1. At this time, the part of the drum 1 that cooperates with the contact groove 901 will further heat the material, allowing the material to be further dried, while making further use of heat and saving energy. When the material to be dried produces polluting gas, the polluting gas will come into contact with the activated carbon plate 703 in the cooperation of the through hole on the inner side of the drum 1 when it passes through the discharge port of the drum 1, allowing the activated carbon plate 703 to filter out the harmful substances. After the material is dried, it will flow out from the end of the drum 1 near the support rod 13, and a container will be placed at the bottom of the drum 1 to collect the dried material.

[0042] Example 2: The difference between this embodiment and embodiment one is that when the contact plate 607 is pushed back to its original position by the spring after separating from the contact strip 608, the contact plate 607 will hit the roller 1, and the inner side of the roller 1 and the contact plate 607 will vibrate. The vibration of the contact plate 607 will be transmitted to the rocking plate 606 through the spring, so that the surface of the rocking plate 606 and the inner side of the roller 1 will vibrate, thereby shaking off the adhering material and reducing the problem of sticky wet material.
