Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a ceramic fiber filter tube drying device. Background Art

[0002] Ceramic fiber filter tube is an important equipment for filtering and separating solid particles. It is widely used in environmental protection fields such as dust removal and denitrification. During use, ceramic fiber filter tubes need to be dried to remove moisture and improve their filtration efficiency and service life. The ceramic fiber filter tube drying device is designed to meet this demand.

[0003] However, the current problem is that when drying the ceramic fiber filter tubes, some existing drying devices mostly arrange the ceramic fiber filter tubes in layers, and the upper filter tubes will block part of the surface area of ​​the lower filter tubes, causing the lower filter tubes to receive less hot air, further exacerbating the problem of uneven drying. Especially when there are many layers and the spacing between each layer is small, the shielding effect is more obvious, which will cause the ceramic fiber filter tubes at different positions to be heated unevenly, thereby affecting the drying effect; secondly, when the drying is nearing the end, due to the friction between the filter tube material and the clamping components and the thermal stress caused by possible temperature gradient differences, the clamping parts may experience increased wear, which will not only affect the service life of the filter tubes, but may also have an adverse effect on subsequent processing processes.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1, refer to Figure 1-Figure 7 A ceramic fiber filter tube drying device includes a drying tank 1 and a ceramic fiber tube 10. The drying tank 1 is used as a main body to provide a closed space required for drying. A movable door 101 is hinged on one side of the drying tank 1. The middle of the drying tank 1 is connected with a hot air vent 102, an exhaust port and a circulation device to ensure that the hot air circulates in the tank and takes away moisture. A temperature meter and a humidity meter are set in the drying tank 1 to monitor and adjust the drying conditions in real time. It also includes:

[0038] Rotation adjustment component: The rotation adjustment component is arranged on the drying tank 1, and is used to control the ceramic fiber tube 10 to revolve and rotate in the drying tank 1;

[0039] Hydraulic clamping assembly: The hydraulic clamping assembly is arranged on the rotation adjustment assembly, and the hydraulic clamping assembly adaptively clamps the ceramic fiber tube 10 from the inside of the ceramic fiber tube 10;

[0040] Magnetic pressure reduction component: The magnetic pressure reduction component is arranged inside the hydraulic clamping component. The magnetic pressure reduction component reduces the clamping force on the ceramic fiber tube 10 according to the heat and drying conditions of the clamping part of the ceramic fiber tube 10.

[0041] Furthermore, the rotation adjustment component includes a motor 2 and a turntable 301. The motor 2 is fixedly installed on the outer side wall of the drying tank 1 away from the movable door 101. The output shaft of the motor 2 passes through the installation side wall of the motor 2 and the turntable 301. The end of the output shaft of the motor 2 is fixedly connected to the driving gear 201. A fixed gear ring 203 is fixedly installed inside the drying tank 1 close to the motor 2. The turntable 301 is located between the installation side wall of the motor 2 and the fixed gear ring 203 and is rotatably arranged. The driving gear 201 and the fixed gear ring 203 are meshed and arranged with a plurality of rows. Planetary gear 202, when motor 2 rotates, under the action of driving gear 201 and fixed gear ring 203, planetary gear 202 will rotate along driving gear 201 and fixed gear ring 203 (rotate and revolve), planetary gear 202 is fixedly connected with connecting rod 3 and limiting ring 302 for limiting the position of planetary gear 202, the end of connecting rod 3 close to motor 2 is rotatably connected to the inside of rotating disk 301, when planetary gear 202 rotates around fixed gear ring 203, driven by connecting rod 3, it can synchronously drive rotating disk 301 to rotate;

[0042] The rotation adjustment component also includes a screw rod 4, the end of the screw rod 4 located outside the drying tank 1 is fixedly connected to a hand wheel, the screw rod 4 is threadedly connected to the movable door 101, and the driving disk 401 can move forward and backward along the axial direction of the drying tank 1. The end of the screw rod 4 located inside the drying tank 1 is rotatably clamped with the driving disk 401, and multiple connecting rods 3 are rotatably clamped on the driving disk 401. By rotating the hand wheel, the position of the driving disk 401 can be adjusted through the screw rod 4, and then the front and rear positions of the connecting rods 3 on the driving disk 401 can be adjusted.

[0043] It should be noted that the connecting rods 3 located on the driving disk 401 and the rotating disk 301 are arranged opposite to each other, and the connecting rods 3 facing the middle of the drying tank 1 are fixedly installed with connecting disks 5, and the cross-section of the connecting disks 5 is convex-shaped. Through the relatively arranged connecting disks 5 and the setting of the screw 4, the two ends of the ceramic fiber tube 10 can be preliminarily positioned. A plurality of connecting rods 3 are distributed in a circular and equidistant manner along the central axis of the drying tank 1 to ensure the support stability. The end diameter of the connecting disk 5 facing the middle of the drying tank 1 is smaller than the inner diameter of the ceramic fiber tube 10, ensuring that the ceramic fiber tube 10 can be sleeved on the connecting disk 5. When the driving disk 401 is in contact with the movable door 101, the connecting rods 3 and the connecting disk 5 on the driving disk 401 will not conflict with the inner wall of the drying tank 1 when the movable door 101 rotates.

[0044] In this embodiment, before drying, the movable door 101 is opened, one end of the ceramic fiber tube 10 is inserted into the connecting disk 5 near the rotating disk 301, and then the driving disk 401 is adjusted to a position roughly corresponding to the other end of the ceramic fiber tube 10 (it should be noted that the length of the connecting disk 5 is moderate to ensure that one end of the ceramic fiber tube 10 can be effectively supported to prevent it from slipping), the movable door 101 is closed, and the hand wheel is turned to rotate the screw 4 through the action of the screw 4, thereby adjusting the position of the driving disk 401 so that the connecting disk 5 on it is The receiving disc 5 is in close contact with the other end of the ceramic fiber tube 10 and is effectively clamped. This clamping effect not only prevents the ceramic fiber tube 10 from slipping or deflecting during the rotation process, but also transmits power from the driving disc 401 to the ceramic fiber tube 10 through the connecting rod 3, thereby achieving stable driving thereof. After completing fine-tuning and fixing, the installation of the ceramic fiber tube 10 is checked again to ensure that it is stable and correct. After ensuring that the ceramic fiber tube 10 is installed firmly and correctly, the hot air vent 102, the exhaust port and the circulation device in the drying tank 1 are started to start generating and circulating hot air.

[0045] Start the motor 2, which drives the driving gear 201 to rotate. Under the joint action of the driving gear 201 and the fixed gear ring 203, the planetary gears 202 start to work. They not only rotate on their own but also revolve around the fixed gear ring 203. When the planetary gears 202 revolve, the turntable 301 is driven to rotate synchronously through the transmission effect of the connecting rod 3. The rotation of the turntable 301 then transmits power to the ceramic fiber tube 10 through the connecting rod 3 and the connecting disk 5, so that it can revolve. At the same time, since the connecting rod 3 is fixedly connected to the planetary gears 202, the ceramic fiber tube 10 will rotate on its own axial direction while revolving with the rotation of the planetary gears 202. This part of the movement will be promptly transmitted to the driving disk 401 and the connecting rod 3 thereon through the connecting disk 5 on the other side, prompting it to rotate. Therefore, both ends of the ceramic fiber tube 10 are connected to the entire rotating system, realizing a perfect combination of revolution and rotation.

[0046] This combination of revolution and rotation ensures that the inner and outer surfaces of each ceramic fiber tube 10 can obtain sufficient hot air contact, which helps the hot air to form a uniform airflow layer on the surface of the ceramic fiber tube 10, thereby improving the drying efficiency and achieving a more uniform drying effect. It also helps to reduce the temperature gradient during the drying process, avoid local overheating or insufficient drying, and thus improve the overall drying efficiency and uniformity.

[0047] Example 2, refer to Figure 4-Figure 11The hydraulic clamping assembly includes a liquid storage chamber 6 and an active chamber 701 arranged in the connecting plate 5. A slider 7 is slidably arranged inside the active chamber 701. A pressure ring 501 is slidably connected to the liquid storage chamber 6. The liquid storage chamber 6 is filled with a hydraulic medium. The hydraulic medium can be synthetic oil, which has excellent performance and stability, can be used in extreme high and low temperature environments, does not contain impurities, and will not corrode or oxidize. When the system is working, the hydraulic medium plays a role in transmitting pressure. The pressure ring 501 is elastically connected to the inner wall of the liquid storage chamber 6 through a first spring 502, and the inner side of the liquid storage chamber 6 away from the pressure ring 501 is The wall is provided with a liquid conducting channel 601, and the connecting disk 5 and the active cavity 701 are connected through the liquid conducting channel 601. The number of liquid conducting channels 601 and the active cavity 701 is equal and they are all distributed in a circular shape and equidistantly. When the ceramic fiber tube 10 is sleeved on the connecting disk 5, the end of the ceramic fiber tube 10 will squeeze the pressure ring 501 and compress the first spring 502. After being squeezed by the pressure ring 501, the hydraulic medium will enter the active cavity 701 through the corresponding liquid conducting channel 601, so that the slider 7 can be lifted up and fixed from the inside of the ceramic fiber tube 10.

[0048] Furthermore, the slider 7 is in an arc-shaped block shape and its cross section is in a convex shape to increase the contact area and clamping stability with the ceramic fiber tube 10. The slider 7 is elastically connected to the active cavity 701 through a second spring 702. The second spring 702 is responsible for the buffering and resetting of the slider 7. The end of the slider 7 extends to the outside of the connecting disk 5 to facilitate interaction with the ceramic fiber tube 10. The side wall of the connecting disk 5 is provided with a notch matching the slider 7. The outer side wall of the slider 7 is recessed inwardly and provided with a ventilation groove 703. This design reduces the contact area between the slider 7 and the ceramic fiber tube 10, while increasing the ventilation volume and friction, which helps to improve the clamping effect.

[0049] It should be noted that the bottom wall of the slider 7 in the initial state fits with the bottom wall of the active cavity 701, ensuring that the ceramic fiber tube 10 can be smoothly placed on the connecting plate 5 without being easily obstructed. The liquid storage cavity 6 and the pressure ring 501, and the slider 7 and the active cavity 701 are all sealed to prevent the hydraulic medium from overflowing from the gap.

[0050] In this embodiment, when the ceramic fiber tube 10 is sleeved on the connecting disk 5, its end portion will squeeze the pressure ring 501, thereby compressing the first spring 502. This action causes the hydraulic medium in the liquid storage chamber 6 to be squeezed and flow into the active chamber 701 through the liquid guide channel 601. As the hydraulic medium enters, the slider 7 in the active chamber 701 is lifted up, thereby lifting the slider 7. The lifted slider 7 can lift and fix the ceramic fiber tube 10 from the inside. When the ceramic fiber tube 10 needs to be released, the hand wheel is turned to move the driving disk 401 away from the ceramic fiber tube 10. Under the elastic force of the first spring 502, the pressure ring 501 can be reset, and the hydraulic medium flows back to the liquid storage chamber 6. The slider 7 is reset under the action of the second spring 702, thereby releasing the ceramic fiber tube 10.

[0051] The user only needs to insert the ceramic fiber tube 10 into the connecting plate 5 from the outside and push it gently to achieve adaptive fixation. This design avoids complicated mechanical adjustment or clamping process and improves operating efficiency. Since the slider 7 can automatically adjust its position under the action of the hydraulic medium to adapt to ceramic fiber tubes 10 with different inner diameters, the clamping assembly can handle ceramic fiber tubes 10 of various specifications without replacing or adjusting the clamping parts. On the other hand, compared with the traditional external clamping method, the present case adopts an internal lifting method to fix the ceramic fiber tube 10. This method reduces the contact area between the clamping part and the outer wall of the ceramic fiber tube 10, reduces the obstruction to the hot air penetration path, and thus helps the hot air to penetrate more smoothly through the outer wall of the ceramic fiber tube 10 into its inner cavity, so that more heat can be used for the drying process inside the ceramic fiber tube 10, and the impact on the drying effect of the ceramic fiber tube 10 is smaller.

[0052] Example 3, refer to Figure 8-Figure 12 The magnetic pressure reduction component includes a liquid guide cavity 8 and an air storage cavity 9 arranged in the slider 7. The air storage cavity 9 is sealed and slidably connected with a magnetic ring 902. The magnetic ring 902 is elastically connected to the side wall of the air storage cavity 9 facing the inner side of the slider 7 through a third spring 901. Nitrogen is filled between the air storage cavity 9 where the third spring 901 is installed and the magnetic ring 902. Since the drying temperature of the ceramic fiber tube 10 is usually between 200-450°C, during the drying process, when the temperature at the clamping point of the ceramic fiber tube 10 rises to a certain value (due to being blocked by the slider 7, the hot air is transferred from the outside to the inside, and the drying is finally completed here. When the temperature of this part (i.e., the slider 7) rises to a certain value, it means that the drying process is about to end. At this time, the clamping force should be appropriately reduced to avoid damage to the clamping point of the ceramic fiber tube 10 due to hard friction), the filled nitrogen will undergo thermal expansion, and the gas volume expansion will push the magnetic ring 902 to move up and stretch the third spring 901.

[0053] Furthermore, a strong magnetic block 801 is slidably connected in the liquid guide cavity 8, and a round-headed baffle 802 is fixedly connected to the lower end of the strong magnetic block 801. The end of the round-headed baffle 802 extends to the outside of the slider 7. The end of the round-headed baffle 802 located outside the slider 7 is a dome-shaped setting, which reduces the pressure of the hydraulic medium on the round-headed baffle 802. The side wall of the slider 7 is provided with a notch matching the round-headed baffle 802. The round-headed baffle 802 is hollow inside, and a drainage groove 803 is provided on the side wall of the round-headed baffle 802 through its inner cavity.

[0054] It should be noted that the strong magnetic block 801 and the magnetic ring 902 are set with different polar magnetic properties. The magnetic force between the opposite surfaces of the strong magnetic block 801 and the magnetic ring 902 is greater than the sum of the friction forces between the strong magnetic block 801 and the liquid guide cavity 8, and between the magnetic ring 902 and the gas storage cavity 9. When the magnetic ring 902 moves upward, under the action of the magnetic force, the strong magnetic block 801 moves upward synchronously and drives the round-headed baffle 802 to move. When the round-headed baffle 802 moves into the liquid guide cavity 8, a part of the hydraulic medium at this time will enter the liquid guide cavity 8, which is equivalent to reducing the pressure on the slider 7. At this time, the slider 7 will shrink a small distance under the push of the second spring 702. This step can not only reduce the contact force between the slider 7 and the inner wall of the ceramic fiber tube 10 to avoid excessive wear of the clamping point, but also gradually expose the position covered by the slider 7, which can speed up the drying process of the clamping point of the ceramic fiber tube 10. The diameter of the round-headed baffle 802 is smaller than the caliber of the liquid guide channel 601, ensuring that most of the hydraulic medium will directly act on the bottom wall of the slider 7 instead of the round-headed baffle 802. The opening of the drainage groove 803 is small when the third spring 901 is in the initial state, which not only limits the amount of hydraulic medium entering the interior during clamping, but also ensures that the residual hydraulic medium inside can be discharged smoothly after drying.

[0055] In this embodiment, when the ceramic fiber tube 10 is in the drying process, its temperature gradually rises. Since the slider 7 blocks the direct transfer of hot air, its interior (especially the part in contact with the ceramic fiber tube 10) is heated last. When the temperature of this part reaches a certain threshold (indicating that the drying is about to be completed), the nitrogen filled in the gas storage chamber 9 expands due to the heat, pushing the magnetic ring 902 to move upward and stretching the third spring 901. The magnetic ring 902 and the strong magnetic block 801 in the liquid guide chamber 8 are set with different polarities, so there is a strong magnetic attraction between them. When the magnetic ring 902 moves upward, Through the action of magnetic force, the strong magnetic block 801 moves upward synchronously, driving the round-head baffle 802 below it to move together. As the round-head baffle 802 moves, part of the hydraulic medium is able to enter the liquid guide cavity 8, thereby reducing the pressure directly acting on the bottom wall of the slider 7. This allows the slider 7 to shrink a small distance under the elastic force of the second spring 702, which not only reduces the clamping force on the inner wall of the ceramic fiber tube 10 and avoids excessive wear of the clamping point, but also exposes the surface area of ​​the ceramic fiber tube 10 originally covered by the slider 7, thereby accelerating the drying speed of these areas.

[0056] By utilizing the characteristic that the temperature of the ceramic fiber tube 10 gradually rises during the drying process and the physical principle of nitrogen expansion due to heat, adaptive adjustment of the clamping force of the slider 7 is achieved. When the drying is nearly completed, the clamping force is automatically reduced, thereby avoiding excessive wear of the clamping point of the ceramic fiber tube 10 due to excessive clamping force; the reduced clamping force not only reduces the mechanical pressure on the inner wall of the ceramic fiber tube 10, but also reduces the scratches or damage that may be caused by hard friction, thereby protecting the integrity and service life of the ceramic fiber tube 10; the small distance contraction of the slider 7 exposes the surface areas of the ceramic fiber tube 10 originally covered by it, and these areas can be more directly exposed to hot air, thereby accelerating the drying speed. In addition, due to the reduction in clamping force, the conduction of heat inside the ceramic fiber tube 10 is also promoted, further improving the drying efficiency.

[0057] In summary, the magnetic pressure reduction component realizes adaptive adjustment of the clamping force during the drying process of the ceramic fiber tube 10 through multiple mechanisms such as temperature sensing, gas expansion, magnetic linkage and hydraulic medium control. This design not only protects the clamping point of the ceramic fiber tube 10 from clamping damage, but also improves the drying efficiency and extends the service life of the ceramic fiber tube 10.
