Description

Technical Field

[0001] This utility model relates to the field of activated carbon production technology, and in particular to an airflow drying device for activated carbon production. Background Technology

[0002] Drying is a crucial step in activated carbon production, directly impacting its quality and performance. Currently, most traditional activated carbon drying equipment uses a single drying method, failing to achieve layered drying or multiple-cycle drying. In actual drying processes, activated carbon is prone to aggregation, resulting in a small contact area with the hot airflow, uneven drying, and some activated carbon failing to reach the required degree of dryness. Furthermore, single-cycle drying efficiency is low, making it difficult to meet the needs of large-scale production. In addition, activated carbon particles are prone to sticking together during drying, affecting the drying effect and product quality.

[0003] Therefore, we propose an airflow drying device for activated carbon production. Utility Model Content

[0004] The main purpose of this utility model is to provide an airflow drying device for activated carbon production. In order to prevent problems such as uneven drying, low single-drying efficiency, and particle adhesion affecting product quality caused by the accumulation of activated carbon during the drying process, this device can effectively solve the problems in the background art by improving the uniformity, efficiency and product quality of activated carbon drying.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An airflow drying device for activated carbon production includes an outer tank, inside which is an inner tank. Multiple placement trays are vertically arranged on the inner wall of the inner tank. Multiple first through holes are opened at the bottom of each placement tray. A rotating disk is rotatably installed inside each placement tray, and multiple second through holes are opened at the bottom of the rotating disk. A first motor is fixedly installed at the top center of the outer tank. A rotating rod is fixedly connected to the output end of the first motor. The rotating rod passes through the outer tank and the inner tank and is fixedly connected to the rotating disk. A feed hopper passes through the top of the outer tank, and a sealing cover is installed on the top of the feed hopper. The bottom of the feed hopper is connected to the top of the inner tank. A conveying mechanism connected to the inner tank and the feed hopper is provided outside the outer tank.

[0007] By adopting the above technical solution, the sealed cover is opened, and the activated carbon to be dried is poured into the inner tank through the feed hopper. The first motor is started, and its output end drives the rotating rod to rotate, thereby causing the rotating disk to rotate in the placement tray. When the second through hole on the rotating disk is aligned with the first through hole on the placement tray, the activated carbon can move to the next layer of placement tray through the through hole; when misaligned, it temporarily stops falling. In this way, the residence time of the activated carbon on different placement trays can be controlled to achieve layered drying and ensure the drying effect.

[0008] Furthermore, the conveying mechanism includes a fixed frame fixedly connected to the outer wall of the outer tank, a conveying cylinder fixedly installed vertically on the fixed frame, a discharge pipe fixedly connected to one side of the feed hopper on the upper outer side of the conveying cylinder, a feed pipe fixedly connected to the bottom end of the inner tank on the lower outer side of the conveying cylinder, an auger rotatably connected inside the conveying cylinder, and a second motor fixedly installed at the bottom end of the fixed frame, the output shaft of the second motor being fixedly connected to the bottom end of the auger.

[0009] By adopting the above technical solution, the second motor is started, which drives the auger to rotate inside the conveying cylinder. The activated carbon, after being dried in the inner tank, enters the conveying cylinder through the feed pipe and is conveyed upward under the action of the auger. Finally, it re-enters the feed hopper through the discharge pipe and returns to the inner tank for drying again. This cycle allows the activated carbon to undergo the drying process multiple times, improving drying efficiency and uniformity, and ensuring that the activated carbon reaches the required degree of dryness.

[0010] Furthermore, the rotating rod is fixedly connected to the outer walls on both sides of the inner tank, and the bottom end of the horizontal rod is fixedly connected to a plurality of vertically arranged levers, the lower part of which is located inside the placement tray.

[0011] By adopting the above technical solution, when the first motor drives the rotating rod to rotate, the crossbar and the lever rotate accordingly. The lever moves the activated carbon in the placement tray, so that it is evenly distributed on the placement tray, avoiding the accumulation of activated carbon, increasing the contact area between activated carbon and hot air flow, and further improving the drying effect. At the same time, the movement of the lever can also promote the relative movement between activated carbon particles, prevent activated carbon from sticking together, and ensure the smooth progress of the drying process.

[0012] Furthermore, the outer annular array of the inner tank has multiple fixing rods, and the end of the fixing rod away from the inner tank is fixedly connected to the inner wall of the outer tank.

[0013] By adopting the above technical solution, the fixing rod plays the role of supporting and fixing the inner tank, ensuring that the inner tank maintains a stable position within the outer tank. During the operation of the device, especially when the first motor drives the rotating rod to rotate and the conveying mechanism is running, certain vibrations and forces will be generated. The fixing rod can effectively resist these external forces, prevent the inner tank from shifting, shaking or deforming, and ensure the structural stability and operational reliability of the entire drying device.

[0014] Furthermore, a discharge pipe is fixedly connected to the middle of the bottom of the inner tank, the bottom end of the discharge pipe passes through the outer tank and extends to the outside, and a valve is provided on the discharge pipe.

[0015] By adopting the above technical solution, after the activated carbon has been dried multiple times to reach the required drying standard, the valve on the discharge pipe is opened, and the dried activated carbon is discharged from the outer tank through the discharge pipe under the action of gravity, and enters the subsequent collection and processing process. When the valve is closed, the activated carbon can be prevented from being discharged, so that the activated carbon can continue to be dried in the inner tank or wait for unified discharge, which facilitates the control and management of the production process.

[0016] Furthermore, multiple gas supply pipes are vertically arranged on both sides of the inner tank, and the other end of each gas supply pipe extends through the outer tank to the outside and is fixedly connected to the main gas supply pipe. The outer wall of the outer tank has multiple support legs arranged in a ring.

[0017] By adopting the above technical solution, the activated carbon material to be dried is transported into the inner tank through the feed inlet. Then, the external air source equipment is activated, and the hot air flow generated is distributed to each gas distribution pipe through the main gas supply pipe. The hot air flow enters the inner tank along the gas distribution pipe, forming a uniform and strong airflow field inside the tank. Under the impact and entrainment of the hot air flow, the activated carbon material is in a suspended and tumbling state, and is fully in contact with the hot air flow in all directions. The moisture in the material is quickly evaporated and discharged with the air flow. The design of multiple gas distribution pipes arranged vertically and distributed on both sides of the inner tank ensures that the hot air flow can penetrate the material layer from different directions, avoiding drying dead corners and greatly improving drying efficiency and uniformity.

[0018] The outer support legs on the outside of the tank provide stable support, ensuring safe and reliable operation.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The airflow drying device for activated carbon production of this utility model, by setting multiple placement plates and a rotatable rotating plate in the device, and by utilizing the misalignment and alignment of the through holes on the rotating plate and the placement plate, can accurately control the residence time of activated carbon on different placement plates, and achieve layered drying. This method allows the activated carbon to fully contact the hot airflow during the drying process, avoids quality problems caused by insufficient drying, and effectively ensures the drying effect.

[0021] (2) The airflow drying device for activated carbon production of this utility model can send the dried activated carbon back to the feed hopper through the conveying mechanism, so that it can re-enter the inner tank for drying. Through multiple cycles of drying, not only is the drying efficiency significantly improved, but the activated carbon can also achieve a more uniform degree of drying in repeated drying, which meets the strict requirements for the quality of activated carbon drying in the production process, and also meets the needs of large-scale production.

[0022] (3) The airflow drying device for activated carbon production of this utility model has a structure of crossbars and levers fixedly connected to the outer walls on both sides of the inner tank. When the first motor drives the rotating rod to rotate, the crossbars and levers rotate accordingly. The levers move the activated carbon in the placement tray, making it evenly distributed on the tray. This design effectively avoids the accumulation of activated carbon, greatly increases the contact area between the activated carbon and the hot airflow, and further improves the drying effect. At the same time, the continuous movement of the levers can promote the relative movement between the activated carbon particles, effectively prevent the activated carbon from sticking together, ensure a smooth and unobstructed drying process, and guarantee the stability of product quality.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] To prevent problems such as uneven drying, low single-batch drying efficiency, and particle adhesion affecting product quality caused by activated carbon accumulation during the drying process, and to improve the uniformity, efficiency, and product quality of activated carbon drying, such as... Figure 1 , Figure 2 , Figure 3 As shown, an airflow drying device for activated carbon production includes an outer tank 1, an inner tank 2 inside the outer tank 1, multiple placement trays 3 arranged vertically on the inner wall of the inner tank 2, multiple first through holes 4 at the bottom of the placement trays 3, a rotating disk 7 rotatably installed inside the placement trays 3, multiple second through holes 8 at the bottom of the rotating disk 7, a first motor 5 fixedly installed at the top center of the outer tank 1, a rotating rod 6 fixedly connected to the output end of the first motor 5, the rotating rod 6 passing through the outer tank 1 and the inner tank 2 and fixedly connected to the rotating disk 7, a feed hopper 16 passing through the top of the outer tank 1, and a sealing cover 19 installed on the top of the feed hopper 16, the bottom of the feed hopper 16 communicating with the top of the inner tank 2, and a conveying mechanism 11 communicating with the inner tank 2 and the feed hopper 16 on the outside of the outer tank 1.

[0029] In use, open the sealing cover 19 and pour the activated carbon to be dried into the inner tank 2 through the feed hopper 16. Start the first motor 5, and its output end drives the rotating rod 6 to rotate, thereby causing the rotating disk 7 to rotate in the placement disk 3. When the second through hole 8 on the rotating disk 7 is aligned with the first through hole 4 on the placement disk 3, the activated carbon can move to the next layer of placement disk 3 through the through hole; when misaligned, it will temporarily stop falling. In this way, the residence time of the activated carbon on different placement disks 3 can be controlled to achieve layered drying and ensure the drying effect.

[0030] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a conveying mechanism 11 comprising a fixed frame 12 fixedly connected to the outer wall of the outer tank 1, a conveying cylinder 13 vertically fixedly mounted on the fixed frame 12, an outlet pipe 17 fixedly connected to one side of the feed hopper 16 on the upper outer side of the conveying cylinder 13, an inlet pipe 18 fixedly connected to the bottom end of the inner tank 2 on the lower outer side of the conveying cylinder 13, an auger 14 rotatably connected inside the conveying cylinder 13, and a second motor 15 fixedly mounted at the bottom end of the fixed frame 12, the output shaft of the second motor 15 being fixedly connected to the bottom end of the auger 14.

[0031] When in use, the second motor 15 is started, which drives the auger 14 to rotate inside the conveying cylinder 13. The activated carbon, after being dried in the inner tank 2, enters the conveying cylinder 13 through the feed pipe 18 and is conveyed upward under the action of the auger 14. Finally, it re-enters the feed hopper 16 through the discharge pipe 17 and returns to the inner tank 2 for drying again. This cycle allows the activated carbon to undergo the drying process multiple times, improving drying efficiency and uniformity, and ensuring that the activated carbon reaches the required degree of dryness.

[0032] For example, such as Figure 2 As shown, the present invention also includes a horizontal bar 9 fixedly connected to the outer walls on both sides of the rotating rod 6 inside the inner tank 2, and a plurality of vertically arranged levers 10 fixedly connected to the bottom end of the horizontal bar 9, with the lower part of the levers 10 located inside the placement tray 3.

[0033] During use, when the first motor 5 drives the rotating rod 6 to rotate, the crossbar 9 and the lever 10 rotate accordingly. The lever 10 moves the activated carbon in the placement tray 3, so that it is evenly distributed on the placement tray 3, avoiding the accumulation of activated carbon, increasing the contact area between activated carbon and hot air flow, and further improving the drying effect. At the same time, the movement of the lever 10 can also promote the relative movement between activated carbon particles, prevent activated carbon from sticking together, and ensure the smooth progress of the drying process.

[0034] For example, such as Figure 2 As shown, the present invention also includes a plurality of fixing rods 20 arranged in a ring around the outer side of the inner tank 2, wherein one end of the fixing rod 20 away from the inner tank 2 is fixedly connected to the inner wall of the outer tank 1.

[0035] During use, the fixing rod 20 serves to support and fix the inner tank 2, ensuring that the inner tank 2 maintains a stable position within the outer tank 1. During the operation of the device, especially when the first motor 5 drives the rotating rod 6 to rotate and when the conveying mechanism 11 is running, certain vibrations and forces will be generated. The fixing rod 20 can effectively resist these external forces, preventing the inner tank 2 from shifting, shaking or deforming, and ensuring the structural stability and operational reliability of the entire drying device.

[0036] For example, such as Figure 2 As shown, the present invention also includes a discharge pipe 21 fixedly connected to the middle of the bottom end of the inner tank 2, the bottom end of the discharge pipe 21 passing through the outer tank 1 and extending to the outside, and a valve being provided on the discharge pipe 21.

[0037] When in use, after the activated carbon has been dried multiple times to reach the required drying standard, the valve on the discharge pipe 21 is opened. The dried activated carbon is discharged from the outer tank 1 through the discharge pipe 21 under the action of gravity and enters the subsequent collection and processing process. When the valve is closed, the activated carbon can be prevented from being discharged, so that the activated carbon can continue to be dried in the inner tank 2 or wait for unified discharge, which facilitates the control and management of the production process.

[0038] For example, such as Figure 1 As shown, the present invention also includes multiple gas supply pipes 22 arranged vertically on both sides of the inner tank 2, the other end of the gas supply pipe 22 extending through the outer tank 1 to the outside and fixedly connected to the gas supply main pipe 23, and multiple support legs 24 arranged in a ring on the outer wall of the outer tank 1.

[0039] In use, the activated carbon material to be dried is conveyed into the inner tank 2 through the feed port. Then, the external air source equipment is started, and the hot air generated is distributed to each air distribution pipe 22 through the main air supply pipe 23. The hot air enters the inner tank 2 along the air distribution pipe 22, forming a uniform and strong airflow field inside the tank. Under the impact and entrainment of the hot air, the activated carbon material is in a suspended and tumbling state, and is fully in contact with the hot air in all directions. The moisture in the material is quickly evaporated and discharged with the airflow. The design of multiple air distribution pipes 22 arranged vertically and distributed on both sides of the inner tank 2 ensures that the hot air can penetrate the material layer from different directions, avoids drying dead corners, and greatly improves drying efficiency and uniformity.

[0040] The outer support legs 24 on the outside of the outer tank 1 are stable support devices to ensure safe and reliable operation.

[0041] It should be noted that this utility model is an airflow drying device for activated carbon production. The sealing cover 19 at the top of the feed hopper 16 is opened, and the activated carbon to be dried is poured into the inner tank 2 through the feed hopper 16. The first motor 5 is started, and its output end drives the rotating rod 6 to rotate, thereby causing the rotating disk 7 to rotate within the placement disk 3. When the second through hole 8 on the rotating disk 7 aligns with the first through hole 4 on the placement disk 3, the activated carbon can move to the next layer of placement disk 3 through the through hole. When misaligned, the falling is temporarily stopped. In this way, the residence time of the activated carbon on different placement disks 3 can be controlled, achieving layered drying and ensuring the drying effect.

[0042] The second motor 15 is started, driving the auger 14 inside the conveying cylinder 13 to rotate. The activated carbon, after being dried in the inner tank 2, enters the conveying cylinder 13 through the feed pipe 18, is conveyed upward by the auger 14, and finally re-enters the feed hopper 16 through the discharge pipe 17, returning to the inner tank 2 for further drying. This cycle allows the activated carbon to undergo the drying process multiple times, improving drying efficiency and uniformity, ensuring that the activated carbon reaches the required degree of dryness. When the first motor 5 drives the rotating rod 6 to rotate, the crossbar 9 and the lever 10 rotate accordingly. The lever 10 moves the activated carbon in the placement tray 3, ensuring that it is evenly distributed on the tray 3, preventing the activated carbon from piling up, increasing the contact area between the activated carbon and the hot airflow, and further improving the drying effect. At the same time, the movement of the lever 10 also promotes the relative movement between the activated carbon particles, preventing the activated carbon from sticking together and ensuring the smooth progress of the drying process.

[0043] The fixing rod 20 serves to support and fix the inner tank 2, ensuring that the inner tank 2 maintains a stable position inside the outer tank 1. During the operation of the device, especially when the first motor 5 drives the rotating rod 6 to rotate and the conveying mechanism 11 is running, certain vibrations and forces will be generated. The fixing rod 20 can effectively resist these external forces to prevent the inner tank 2 from shifting, shaking or deforming, thus ensuring the structural stability and operational reliability of the entire drying device.

[0044] After the activated carbon has been dried multiple times to reach the required drying standard, the valve on the discharge pipe 21 is opened, and the dried activated carbon is discharged from the outer tank 1 through the discharge pipe 21 under the action of gravity, and enters the subsequent collection and processing process; when the valve is closed, the activated carbon can be prevented from being discharged, so that the activated carbon can continue to be dried in the inner tank 2 or wait for unified discharge, which facilitates the control and management of the production process.

[0045] The activated carbon material to be dried is fed into the inner tank 1 through the inlet. Then, the external air source equipment is activated, and the hot air generated is distributed to each gas branch pipe 22 through the main gas pipe 23. The hot air enters the inner tank 1 along the gas branch pipe 22, forming a uniform and strong airflow field inside the tank. Under the impact and entrainment of the hot air, the activated carbon material is suspended and tumbling, and is fully in contact with the hot air in all directions. The moisture in the material is quickly evaporated and discharged with the airflow. The design of multiple gas branch pipes 22 arranged vertically and distributed on both sides of the inner tank 1 ensures that the hot air can penetrate the material layer from different directions, avoids drying dead corners, and greatly improves drying efficiency and uniformity.
