Description

Technical Field

[0001] The invention relates to the technical field of drying machines, in particular to a noise-reducing and wear-resistant three-drum drying machine. Background Art

[0002] The three-drum dryer is a high-efficiency drying equipment used in industry, mainly used to process large quantities of wet materials, such as mineral powder, clay, fly ash, iron powder, slag, etc. Its core design is to have three concentric rotating cylinders, which are nested in each other to form a continuous drying chamber. Each cylinder undertakes a different drying stage, thereby optimizing heat utilization, accelerating the drying speed, and effectively controlling the moisture content of the final product. In the prior art, there is a three-drum dryer, which includes a feeding and air inlet device, a composite drum, a discharging device and a driving device. The composite drum is composed of three outer drums, a middle drum and an inner drum of different diameters from large to small, which are concentrically mounted. The inner drum, the middle drum and the inner wall of the outer drum are all provided with a lifting plate. The feeding and air inlet device and the discharging device are respectively located at the front end and the rear end of the composite drum. The driving device includes a pin wheel, a gear, a motor, a reducer, a supporting wheel mechanism and a base. The pin wheel is arranged on the middle part of the outer surface of the outer drum, the gear is meshed with the pin wheel, the gear is arranged on the gear shaft, the gear shaft is arranged on the gear seat, the gear seat is arranged on the base, the gear shaft is connected to the reducer, the reducer is connected to the motor, and the reducer and the motor are both arranged on the base. The front and rear parts of the outer surface of the outer drum are respectively provided with a front wheel belt and a rear wheel belt. The supporting wheel mechanism includes a front supporting wheel mechanism and a rear supporting wheel machine, and the front supporting wheel mechanism and the rear supporting wheel machine have the same structure. Both the front roller mechanism and the rear roller machine include a left roller and a right roller, which are arranged on a left roller seat and a right roller seat respectively. The left roller and the right roller of the front roller mechanism are arranged on the left and right sides of the front part of the base, and the left roller and the right roller of the rear roller mechanism are arranged on the left and right sides of the rear part of the base. The front wheel belt at the front of the outer surface of the outer cylinder is located on the left and right rollers of the front roller mechanism, and the rear wheel belt at the rear of the outer surface of the outer cylinder is located on the left and right rollers of the rear roller mechanism. When working, the front wheel belt and the rear wheel belt respectively arranged at the front and rear of the outer cylinder rotate relative to the left and right rollers on the front roller mechanism and the rear roller machine respectively. However, since the front and rear belts and the left and right supporting wheels, as well as the pin wheels and gears are all made of steel, the contact between the front and rear belts and the left and right supporting wheels, as well as between the pin wheels and gears is rigid contact, and affected by the manufacturing and installation accuracy, the composite cylinder not only generates a lot of noise when rotating, which harms the physical and mental health of the operators, but also the belts and supporting wheels, as well as the pin wheels and gears are easily worn and shortened in service life. In addition, when the motor rotates, it will also generate noise due to its vibration, which further increases the noise level of the entire equipment. Summary of the invention

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 4 The present invention provides a technical solution: a noise-reducing and wear-resistant three-drum dryer, comprising: a drum 1, a double-shaft motor 2 is installed on one side of the drum 1, two output ends of the double-shaft motor 2 are fixedly connected to the input end of a reduction box 3, the lower surface of the double-shaft motor 2 is fixedly connected to a support plate 19, the lower surface of the support plate 19 is fixedly connected to an air cushion shock absorber 4, a lever 5 is provided on one side of the air cushion shock absorber 4, a lever block 6 is installed on one side of the lever 5, a slider 7 is provided on the lower side of the lever block 6, a rotating rod 8 is rotatably installed on one side of the slider 7, a first sealing plate 9 is provided at the bottom of the rotating rod 8, a connecting sleeve 10 is rotatably provided on the rotating rod 8, and a second sealing plate 11 is fixedly installed on one side of the connecting sleeve 10.

[0022] The power is transmitted to the reduction box 3 through the dual-axis motor 2, and the power is transmitted through the reduction box 3, thereby driving the cylinder 1 to rotate slowly and smoothly, thereby improving the stability of the entire device and reducing the generation of noise. Then, through the fixed connection between the dual-axis motor 2, the support plate 19, and the air cushion shock absorber 4, the air cushion shock absorber 4 can absorb and buffer the external force through the compression and expansion of the gas therein, thereby providing dynamic support force and shock absorption effect, thereby reducing the stability of the dual-axis motor 2 during operation, and further reducing the noise. During the rotation of the cylinder 1, the limit ring 13 drives the shift rod 5 to rotate. When the shift rod 5 moves to one side of the shift block 6, it drives the shift block 6 to move and slides between the shift block 6. The shift block 6 thereby indirectly drives the slider 7 to slide. The slider 7 thereby indirectly drives the rotating rod 8 to rotate. Under the rotation action of the rotating rod 8, the rotating rod 8 drives the first sealing plate 9 to rotate, and the connecting sleeve 10 drives the second sealing plate 11 to rotate, so that the first sealing plate 9 and the second sealing plate 11 are folded, and then the lubricating oil in the oil storage barrel 24 flows to the ring gear 22 under the drainage action of the guide plate 23, and the wear resistance is increased during the meshing process of the ring gear 22 and the gear 21.

[0023] Embodiment 2: Based on the embodiment 1, wear-resistant rings 12 are fixedly mounted on both sides of the cylinder 1. The wear-resistant ring 12 is fixedly connected with a limiting ring 13 on both sides, and the limiting ring 13 is slidably connected with a wear-resistant wheel 14 on both sides. The wear-resistant ring 12 fixedly sleeved on the cylinder 1 and the wear-resistant wheel 14 slidably connected with the wear-resistant ring 12 are both made of high manganese steel, thereby improving the wear resistance therebetween. The limiting ring 13 limits the wear-resistant wheel 14, thereby improving the stability of the movement between the wear-resistant wheel 14 and the wear-resistant ring 12. The wear-resistant wheel 14 is rotatably sleeved on the fixed shaft 15, and the fixed shaft 15 is fixedly clamped in the support seat 16 on both sides. The lower surface of the support seat 16 is fixedly connected to the vertical plate 17, and the fixed shaft 15 stably supports the wear-resistant wheel 14, and the support seat 16 supports the fixed shaft 15 is limited, a fixed block 18 is provided on one side of the vertical plate 17, the air cushion shock absorber 4 is fixedly connected between the support plate 19 and the fixed block 18, the reduction box 3 is fixedly connected on both sides of the upper surface of the support plate 19, the fixed block 18 and the lower surface of the vertical plate 17 are fixedly connected to the bottom plate, the fixed block 18 stably supports the driving part of the entire device, the input end of the reduction box 3 is fixedly connected to the output end of the dual-axis motor 2, the output end of the reduction box 3 is fixedly connected to one end of the connecting shaft 20, the other end of the connecting shaft 20 is fixedly sleeved in the gear 21, and a gear ring 22 is meshed on one side of the gear 21, and the gear ring 22 is fixedly sleeved on the outer ring surface of the cylinder 1.

[0024] The dual-axis motor 2 is electrically connected to the external terminal control device, and the output end of the dual-axis motor 2 is fixedly connected to the input end of the reduction box 3, thereby driving the reduction box 3 to operate. The reduction box 3 drives the gear 21 to rotate through the connection of the connecting shaft 20, so that the gear 21 and the ring gear 22 are meshed for transmission, and the ring gear 22 drives the cylinder 1 to rotate. Through the deceleration of the reduction box 3, the gear 21 can rotate more slowly, so that it is more stable during the meshing process with the ring gear 22, reducing noise and reducing the wear between the gear 21 and the ring gear 22. At the same time, the vibration of the dual-axis motor 2 can be reduced during operation by setting the air cushion shock absorber 4, and the air cushion shock absorber 4 can be used to reduce the vibration of the dual-axis motor 2 during operation. The gas inside is compressed and expanded to absorb and buffer the external force, thereby providing dynamic support and shock-absorbing effects, thereby reducing the stability of the dual-axis motor 2 during operation, and further reducing the noise. While the cylinder 1 rotates, the cylinder 1 drives the wear-resistant rings 12 fixed at both ends to rotate, and the wear-resistant rings 12 are slidingly connected with the wear-resistant wheels 14, so that under the limiting action of the limiting ring 13, the wear-resistant rings 12 and the wear-resistant wheels 14 slide, thereby improving the stability of the cylinder 1 during rotation. Since the wear-resistant rings 12 and the wear-resistant wheels 14 can slide, the cylinder 1 is smoother during rotation, thereby reducing the wear between the gear 21 and the gear ring 22.

The lower rotating sleeve 32 is installed on the lower side of the upper rotating sleeve 31. The second sealing plate 11 and the connecting sleeve 10 are fixedly connected through a connecting plate 38. The connecting sleeve 10 is provided with three and is arranged in a linear array about the axis of the rotating rod 8 and is rotatably connected with the rotating rod 8 at the same time. The connecting sleeve 10 at the top is fixedly connected to the lower rotating sleeve 32, and one end of the upper rotating sleeve 31 and the lower rotating sleeve 32 is fixedly connected to the sliding rod 30. The upper and lower connecting sleeves 10 are rotatably sleeved in the cylinder 1, and a fixed The fixed plate 33, the lower surface of the fixed plate 33 is fixedly connected to the slider 7, the fixed plate 33 and one side of the shift block 6 are hinged by a hinge 34, the other side of the shift block 6 is fixedly connected to the support frame 25 by an upper tension spring 35, an arc groove 36 is opened on the side of the shift block 6, the arc groove 36 is fixedly connected to one end of the shift rod 5, the other end of the shift rod 5 is fixedly connected to the side wall of the limit ring 13, one side of the fixed plate 33 is fixedly connected to the upper surface of the slider 7, the other side of the fixed plate 33 is fixedly connected to the support frame 25 by an upper tension spring 35, and the arc groove 36 opened on one side of the surface of the shift block 6 facilitates the sliding between the shift rod 5 and the shift block 6.

[0026] During the rotation of the cylinder 1, the cylinder 1 will drive the limiting ring 13 to rotate, so that the limiting ring 13 drives the lever 5 to rotate. The lever 5 is provided with three and is arranged in a circular array about the outer ring surface of the cylinder 1. When the lever 5 moves to the shift block 6, it is first limited by the arc groove 36, so that the lever 5 will move through the shift block 6. The shift block 6 drives the fixed plate 33 to move under the connection action of the hinge 34, and the fixed plate 33 drives the slider 7 to move away from the block 28 under the limit of the slide groove 26. In this process, the lower tension spring 27 and the upper tension spring 35 are both stretched, and the slider 7 slides, so that the limiting groove 29 on one side of the slider 7 slides with the slide rod 30, so that the slide rod 3 0 movement, the sliding rod 30 is fixedly connected with the upper rotating sleeve 31 and the lower rotating sleeve 32, so that the upper rotating sleeve 31 and the lower rotating sleeve 32 rotate, the upper rotating sleeve 31 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the first sealing plate 9 to rotate under the connection of the limiting sleeve 37, and the lower rotating sleeve 32 drives the topmost connecting sleeve 10 to rotate, and drives the remaining connecting sleeves 10 to move under the connection of the connecting plate 38, thereby driving the second sealing plate 11 to rotate, and the upper rotating sleeve 31 and the lower rotating sleeve 32 are not arranged on the same side, so that the upper rotating sleeve 31 and the lower rotating sleeve 32 rotate in opposite directions, and then the first sealing plate 9 and the second sealing plate 11 rotate in opposite directions, so that the first sealing plate 9 and the second sealing plate 11 rotate in opposite directions, thereby The angle between the plates 11 becomes smaller, so that the lubricating oil in the oil storage barrel 24 flows out, and flows to the ring gear 22 under the drainage effect of the guide plate 23, thereby lubricating the ring gear 22 and the gear 21, thereby increasing the wear resistance between the gear 21 and the ring gear 22 and improving the service life.

At the same time, the upper tension spring 35 continues to be pulled, and the lubricating oil continues to flow out until the shift lever 5 slides out of the arc groove 36. Under the reverse pulling force of the upper tension spring 35, the shift block 6 is reversely rotated and reset. At the same time, because the shift block 6 is no longer limited, the lower pull spring 35 is used to pull the shift block 6 downward. Under the reverse pulling force of the spring 27, the lower pull spring 27 pulls the slider 7 to slide in the reverse direction until it abuts against the block 28.
