Description

The existing drum dryer is mainly composed of a heating device, a feeding device, a supporting wheel device, a drying kiln body, a transmission device, a supporting and blocking wheel device, a discharging device, a cyclone separator and an air blower. The rotating drum of the existing drum dryer is a slightly inclined and rotatable cylindrical body. Wet materials enter from the upper end of one end, and dry materials are collected from the lower end of the other end. Hot air enters from the feeding end and is discharged from the discharging end. The drum is provided with a forward lifting plate, so that the materials are continuously lifted and poured during the rotation of the drum body, so that the materials are fully contacted with the hot air flow, thereby completing the drying of the materials and continuously transporting the materials.

[0023] Embodiment two

[0024] On the basis of embodiment one, please refer to Figures 1-5The inner side wall of the fixed partition plate 3 is fixedly provided with an electrically conductive ring 15, the second rotating barrel 4 is movably provided with a second rotating shaft 16, the outer part of the second rotating shaft 16 is fixedly sleeved with a second rotating plate 17, the side surface of the second rotating shaft 16 is movably provided with a second material scraping plate 18, the inner surface of the side of the second rotating plate 17 is fixedly provided with a second impact block 19, the middle part of one end of the second rotating barrel 4 is fixedly provided with a rear fixed plate 20 located at one end of the second rotating shaft 16, the surface of one end of the second rotating shaft 16 is slidably connected with the rear fixed plate 20, and the bottom end of the discharging cavity 5 is provided with a discharging port 21.

[0025] Please refer to Figures 1-5Wherein, the first rotating shaft 8 and the second rotating shaft 16 are the same shape, the first rotating plate 9 and the second rotating plate 17 are the same shape, the first impact block 11 and the second impact block 19 are the same shape, the second rotating shaft 16 has several, the number of the first rotating shaft 8 is twice the number of the second rotating shaft 16, the first rotating shaft 8 and the second rotating shaft 16 are both circumferentially distributed, the number of the first material plate 10 is also twice the number of the second material plate 18, the shape of the first material plate 10 and the second material plate 18 is both "L" shape, and the horizontal section of the first material plate 10 and the second material plate 18 is both arc-shaped and matches the inner wall arc of the first rotating cylinder 2 and the second rotating cylinder 4, the length of the horizontal section of the second material plate 18 is twice the length of the horizontal section of the first material plate 10, the shape of the first rotating plate 9 and the second rotating plate 17 is both "J" shape, and the first rotating plate 9 and the second rotating plate 17 are respectively connected with the surface of the first rotating shaft 8 and the second rotating shaft 16 through the torsional spring, by setting the first rotating shaft 8, the first rotating plate 9, the first material plate 10, the first impact block 11, the second rotating shaft 16, the second rotating plate 17, the second material plate 18 and the second impact block 19, when the gas is continuously filled into the inside of the first rotating cylinder 2 and the second rotating cylinder 4 through the gas inlet cavity 1, because of the specific number of the first rotating shaft 8 and the second rotating shaft 16 and the first material plate 10 and the second material plate 18, the gap volume of the inner cavity of the first rotating cylinder 2 separated by the first material plate 10 will be much smaller than the gap volume of the inner cavity of the second rotating cylinder 4 separated by the second material plate 18, so when the gas flow passes through the inner cavity of the first rotating cylinder 2, the hot gas flow speed in the inner cavity of the first rotating cylinder 2 will be greater than that in the inner cavity of the second rotating cylinder 4, because of the increased flow speed, the hot gas flow stays in the inner cavity of the first rotating cylinder 2 for a shorter time, so the heat conduction is relatively small and the heat loss is reduced, so when the hot gas flow flows through the first rotating cylinder 2 to the inner cavity of the second rotating cylinder 4, the hot gas flow contains sufficient heat, and because the hot gas flow speed in the inner cavity of the second rotating cylinder 4 is small, the gas flow stays for a long time, the heat conduction effect is high, so it can fully meet the heat required by the material in the inner cavity of the second rotating cylinder 4, and because the initial temperature of the gas flow is very high, that is, the heat is high, so when the gas flow passes through the inner cavity of the first rotating cylinder 2, although the flow speed is accelerated, the heat value that the gas flow can transfer can still meet the heat value required by the material in the inner cavity of the first rotating cylinder 2, therefore, by adjusting the flow speed of the gas flow in the first rotating cylinder 2 and the second rotating cylinder 4, the heat conduction is correspondingly changed, so that the heat of the first rotating cylinder 2 and the second rotating cylinder 4 is balanced, the heat deviation is small, the drying degree of the material is relatively uniform, the drying quality of the material is effectively improved, and the problem that the existing roller dryer can only make the hot gas flow from the feeding end to the discharging end directly, the heat of the gas flow is gradually lost and attenuated, and then the heat of the feeding end is too high and the heat of the discharging end is too low, thereby causing uneven drying of the material is avoided.

[0026] Please refer toFigures 1-5 Wherein, the shape of the pressure bag 12 is rectangular, the inside of the pressure bag 12 is hollow, the inside of the pressure bag 12 is filled with gas, the length of the pressure bag 12 is adapted to the sum of the length of the first rotating shaft 8 and the second rotating shaft 16, the number of the pressure bag 12 is adapted to the number of the second material scraping plate 18, the pressure bag 12 is evenly distributed in a circle, and each pressure bag 12 is located at one end of the horizontal section of each second material scraping plate 18.

[0027] Please refer to Figures 1-5The small motor 13 is a servo motor, the rotatable angle of the small motor 13 is ninety degrees, the conductive sheet 14 has conductivity, the conductive ring 15 is in the shape of a ring, and the lower half of the conductive ring 15 has conductivity, and the upper half does not have conductivity. One end of each second rotating shaft 16 is also provided with a set of small motor 13 and conductive sheet 14. When the first rotating cylinder 2 and the second rotating cylinder 4 continuously rotate to dry the material, the internal components of the first rotating cylinder 2 and the second rotating cylinder 4 rotate at the same time. When the conductive sheet 14 reaches the lower half of the conductive ring 15 and touches the surface of the conductive ring 15, the conductive sheet 14 and the conductive ring 15 conduct electricity, and then the external power current is introduced to the small motor 13, so that the small motor 13 is powered on and operates. However, because the small motor 13 only rotates one quarter of a circle, the first rotating plate 9 and the second rotating plate 17 are both rotated outward by a certain angle. At this time, the material on the upper part of the first rotating cylinder 2 and the second rotating cylinder 4 flows downward, and the falling material falls into the gap formed by the first material scraping plate 10 and the second material scraping plate 18. At this time, the first rotating plate 9 and the second rotating plate 17 located at the lower part are inclined outward due to the rotation of the small motor 13, and then when the upper material falls, the material slides down along the slope formed by the first rotating plate 9 and the second rotating plate 17. At this time, the first rotating plate 9 and the second rotating plate 17 form a funnel-shaped cavity with the inner cavity wall of the first material scraping plate 10 and the second material scraping plate 18, respectively. A large amount of material accumulates in this cavity, and the gap between the end point of the first rotating plate 9 and the second rotating plate 17 and the inner wall of the first material scraping plate 10 and the second material scraping plate 18 allows the material to continue to flow downward and eventually remain in the inner cavity of the first material scraping plate 10 and the second material scraping plate 18. Therefore, when the material flows out through the gap at the slope end point of the first rotating plate 9 and the second rotating plate 17, the material forms a fine stream and flows into the inner cavity of the first material scraping plate 10 and the second material scraping plate 18 in a dispersed manner. When the material flows in, it contacts the hot air flow inside the first material scraping plate 10 and the second material scraping plate 18 more and more completely, thereby effectively improving the material drying efficiency and avoiding the problem that a large amount of material accumulates and cannot be dispersed when the material is scraped by the existing scraping plate and then falls to the lower part, thereby causing the lower material to not be in contact with the hot air during the operation process, and the material in the deep accumulation layer cannot be dried.

[0028] Furthermore, when the first rotating shaft 8 and the second rotating shaft 16 drive the small motor 13 and the conductive sheet 14 to rotate away from the lower half-circle surface of the conductive ring 15, at this time, the conductive sheet 14 and the conductive ring 15 form a power-off, and then the small motor 13 is no longer powered, so that the small motor 13 is powered off and reset, when the small motor 13 is reset in reverse, the small motor 13 will drive the first rotating plate 9 and the second rotating plate 17 to rotate inward, when the first rotating plate 9 and the second rotating plate 17 rotate inward and reset, the first rotating plate 9 and the second rotating plate 17 drive the first impact block 11 and the second impact block 19 to move inward, and then the first impact block 11 and the second impact block 19 will rush to and collide with the vertical section surface of the first material scraping plate 10 and the second material scraping plate 18, causing impact to the first material scraping plate 10 and the second material scraping plate 18, and the first material scraping plate 10 and the second material scraping plate 18 will produce a tendency to rotate outward due to the impact force, when one of the first material scraping plates 10 is impacted and produces a movement tendency, it will transmit the impact to the surface of the adjacent first material scraping plate 10, causing impact to the adjacent first material scraping plate 10, and then the adjacent first material scraping plate 10 also produces a movement tendency, but because one end of the adjacent first material scraping plate 10 is provided with the compressed air bag 12, the inside of the compressed air bag 12 is full of gas, and the elasticity of the gas is used to buffer and reduce the impact, and in the buffering process, the first material scraping plate 10 will produce reciprocating vibration, and the second material scraping plate 18 will also produce reciprocating vibration, when the first material scraping plate 10 and the second material scraping plate 18 vibrate, the materials inside the first material scraping plate 10 and the second material scraping plate 18 will gradually scatter under the influence of vibration, and then cannot form a large-area high-scale accumulation, and the scattered materials have a larger contact surface with hot air, so that the heat transfer efficiency is higher, the drying effect is better, and the drying quality is further improved, and at the same time, the compressed air bag 12 can also prevent component damage.

[0029] At the same time, because the length of the horizontal section of the second stripping plate 18 is twice the length of the horizontal section of the first stripping plate 10, that is, the second stripping plate 18 is equivalent to two first stripping plates 10, and when a certain first stripping plate 10 generates a movement trend to collide with another first stripping plate 10, the second stripping plate 18 will directly impact the surface of the pressure air bag 12, and after the first stripping plate 10 impacts another first stripping plate 10, the first stripping plate 10 impacts the pressure air bag 12 again. At this time, due to the impact of the second stripping plate 18, the gas inside the pressure air bag 12 will flow towards the end of the first stripping plate 10, and the internal pressure of the end of the pressure air bag 12 towards the first stripping plate 10 increases, and when the first stripping plate 10 impacts the surface of the pressure air bag 12, the gas inside the pressure air bag 12 flows opposite to the impact of the first stripping plate 10, and the two generate relative impact, thereby causing the impact force at this place to be larger. Because the impact force is larger, the vibration at the first stripping plate 10 is larger than the vibration at the second stripping plate 18, thereby making the degree of shaking of the material in the inner cavity of the first rotating cylinder body 2 larger, making the material in the inner cavity of the first rotating cylinder body 2 better contact with the hot gas flow, and the drying effect is further improved. At the same time, the drying efficiency of the material inside the first rotating cylinder body 2 is improved, which can relatively avoid the defect problem that the material inside the first rotating cylinder body 2 is not completely dried due to the fast airflow speed, thereby ensuring that the material inside the first rotating cylinder body 2 and the second rotating cylinder body 4 is evenly and completely dried.

[0030] The working principle of the use method of the present application is as follows:

[0031] When the material needs to be dried, the existing roller device and the related power supply are started first, and the first rotating drum 2 and the second rotating drum 4 start to rotate circularly through the roller device. When the first rotating drum 2 and the second rotating drum 4 rotate stably, the material that needs to be dried is continuously poured into the first rotating drum 2 through the feeding pipe 6. Hot air is continuously poured into the inside of the first rotating drum 2 and the second rotating drum 4 through the air inlet cavity 1 by using the existing air pump. Because the pipe opening of the feeding pipe 6 is aligned with the center of the first rotating drum 2 and the second rotating drum 4, the initial hot air can only seep into and flow through the gap at the edge of the first rotating drum 2 and the second rotating drum 4. The material flows into the inner cavity of the first rotating drum 2 through the pipe opening of the feeding pipe 6 first. The scattered material flows to the gap cavity formed by the first material lifting plate 10 through the first rotating shaft 8 and is stacked on the surface of the first material lifting plate 10. Under the continuous rotation of the first rotating drum 2, the material is continuously lifted from below to above, moves to the upper part, and then falls to the lower part through the gap between the first rotating shaft 8, so as to continuously circulate, so that the material is continuously in contact with the hot air, thereby achieving the drying effect. At the same time, because the material is continuously circulated and rotated, the material is gradually transferred to the second rotating drum 4. The material at the second rotating drum 4 is lifted and falls by the second material lifting plate 18 in the same way as at the first rotating drum 2, so as to be dried. Until the material is transferred out of the inner cavity of the second rotating drum 4 and falls into the inner cavity of the discharging cavity 5, the material is discharged through the discharging opening 21, thereby achieving the discharging effect.

[0032] When the conductive sheet 14 reaches the lower half of the conductive ring 15 and contacts the surface of the lower half of the conductive ring 15, the current from the external power source is conducted to the small motor 13 through the conductive sheet 14 and the conductive ring 15, and the small motor 13 is energized and starts to operate. Since the small motor 13 is a servo motor and can rotate by 90 degrees, when the small motor 13 is fully rotated to the maximum angle, the small motor 13 drives the first rotating plate 9 and the second rotating plate 17 to rotate outward to a certain angle. At this time, the material located at the upper part of the first rotating drum 2 and the second rotating drum 4 starts to flow downward through the gap between the first rotating shaft 8 and the second rotating shaft 16. The falling material drops into the gap formed by the first material collecting plate 10 and the second material collecting plate 18, but the upper material is hindered by the inclination of the first rotating plate 9 and the second rotating plate 17 located at the lower part, and thus the upper material drops into a funnel-shaped cavity formed by the first rotating plate 9 and the first material collecting plate 10, and the second rotating plate 17 and the second material collecting plate 18. The material forms a material pile and temporarily stays in the cavity. Since the gap between the end points of the first rotating plate 9 and the second rotating plate 17 and the inner wall surface of the first material collecting plate 10 and the second material collecting plate 18 allows the material to continue to flow downward, but the gap is small due to the inclination of the first rotating plate 9 and the second rotating plate 17, when the material pile flows out of the gap, the material forms a fine stream and flows into the inner cavity of the first material collecting plate 10 and the second material collecting plate 18 in a dispersed state, thereby increasing the contact surface of the material with the hot air flow inside the first material collecting plate 10 and the second material collecting plate 18, and making the drying of the material more complete, and fully improving the drying efficiency of the material.

[0033] When the first rotating shaft 8 and the second rotating shaft 16 drive the small motor 13 and the conductive sheet 14 to rotate away from the lower half-circle surface of the conductive ring 15, the conductive sheet 14 and the conductive ring 15 are separated at this time, and the external current cannot be conducted to the small motor 13, and the small motor 13 is powered off, and starts to reset reversely. When the small motor 13 reversely resets, the small motor 13 drives the first rotating plate 9 and the second rotating plate 17 to rotate inward, and the first rotating plate 9 and the second rotating plate 17 drive the first impact block 11 and the second impact block 19 to move inward, and then the first impact block 11 and the second impact block 19 will rush to and collide with the vertical surface of the first material scraping plate 10 and the second material scraping plate 18, causing impact on the first material scraping plate 10 and the second material scraping plate 18. The first material scraping plate 10 and the second material scraping plate 18 will produce a tendency to rotate outward due to the impact force. When one of the first material scraping plates 10 is impacted and produces a movement tendency, it will transmit the impact to the surface of the adjacent first material scraping plate 10, causing impact on the adjacent first material scraping plate 10, and then the adjacent first material scraping plate 10 also produces a movement tendency. However, because one end of the adjacent first material scraping plate 10 is provided with the compressed air bag 12, the inside of the compressed air bag 12 is full of gas, and the elasticity of the gas is used to buffer and reduce the impact. In the buffering process, the first material scraping plate 10 will produce reciprocating vibration, and the second material scraping plate 18 will also produce reciprocating vibration. When the first material scraping plate 10 and the second material scraping plate 18 vibrate, the materials inside the first material scraping plate 10 and the second material scraping plate 18 will be affected by the vibration and will be scattered, and then cannot form a large area and high scale accumulation, and the contact area of the scattered materials with the hot gas is increased, thereby improving the heat transfer efficiency and making the drying effect better, and further improving the drying quality.
