Description

Technical Field

[0001] This utility model relates to the field of activated carbon regeneration technology, specifically to a modular activated carbon regeneration furnace with flexible connection. Background Technology

[0002] Powdered activated carbon is an adsorbent material with a highly developed pore structure, a large specific surface area, and is non-toxic and odorless. It has a strong ability to adsorb molecules and has been widely used as an adsorbent and decolorizing agent in many fields such as medicine, chemical industry, light industry, food, and environmental protection. In environmental protection, activated carbon adsorption is widely used in the purification of polluted water sources and the deep treatment of urban sewage and industrial wastewater, and is one of the important means of treating organic wastewater.

[0003] Powdered activated carbon has a high manufacturing cost, and discarded saturated activated carbon not only wastes resources but also causes secondary environmental pollution. Therefore, from both economic and environmental perspectives, it is of great significance to effectively regenerate activated carbon and improve its utilization efficiency.

[0004] Therefore, there is an urgent need for an activated carbon regeneration furnace. Existing activated carbon regeneration furnaces only have a single furnace body or a simple heating chamber, with a limited heating area for the activated carbon powder. This can easily lead to localized overheating or underheating. They are also unable to effectively cope with displacement and deformation of the furnace body due to temperature changes or vibrations, causing problems such as shaking or shifting during operation. Furthermore, the lack of a coalescing effect on the activated carbon powder makes it easy for the powder to disperse during transmission, hindering precise transmission and failing to effectively guarantee the feeding speed and the pushing pressure at the discharge port, which can easily lead to blockage of the activated carbon powder in the pipeline. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a modular activated carbon regeneration furnace with flexible connections.

[0006] The technical solution of this utility model is: a modular activated carbon regeneration furnace with flexible connection, comprising multiple sub-furnace bodies arranged from top to bottom and equipped with heating plates inside, a spiral conveying unit disposed in each of the sub-furnace bodies, a driving unit connected to the spiral conveying unit, and a flexible heat insulation unit disposed on each sub-furnace body.

[0007] The upper and lower ends of the sub-furnace body are provided with staggered material inlets and outlets. Between two adjacent sub-furnace bodies, the outlet of the upper sub-furnace body and the material inlet of the lower sub-furnace body are connected by a metal corrugated pipe. The side wall of the sub-furnace body is provided with an exhaust pipe.

[0008] The flexible insulation unit includes an upper insulation frame located at the upper end of the sub-furnace body and a lower insulation frame located at the lower end of the sub-furnace body. The flexible insulation units between two adjacent sub-furnace bodies are interlocked.

[0009] Furthermore, each of the sub-furnace bodies is provided with a material guiding channel that gradually narrows in size. The material discharge port and the material outlet respectively pass through the material guiding channel. The spiral conveying unit includes a spiral stirring rod disposed in the material guiding channel, a rotating gear connected to the spiral stirring rod, and a transmission chain for connecting each of the rotating gears. The driving unit drives one of the rotating gears to rotate.

[0010] Explanation: By setting up a guide channel with a gradually decreasing opening along the direction of charcoal powder conveying, the charcoal powder can be heated more fully within the channel. At the same time, it can gather the charcoal powder, allowing it to move more accurately towards the discharge port and reducing the dispersion of charcoal powder during the conveying process.

[0011] Furthermore, the pitch of the stirring blades on the spiral stirring rod decreases sequentially, with the largest pitch on the stirring blades located on the side of the discharge port and the smallest pitch on the stirring blades located on the side of the discharge port.

[0012] Explanation: The variable pitch spiral agitator increases the pushing pressure of charcoal powder at the discharge port while ensuring the feeding speed, ensuring that the charcoal powder can be smoothly pushed out and enter the next sub-furnace body, preventing charcoal powder from clogging in the pipeline, and ensuring the continuity of the entire regeneration process.

[0013] Furthermore, both the upper and lower heat insulation frames are filled with silicon carbide sand, and both the upper and lower heat insulation frames are detachable structures.

[0014] Explanation: The flexible connecting convex frame at the upper end of the sub-furnace body and the insertion groove at the lower end of the sub-furnace body are flexibly connected. This can compensate for the displacement and deformation of the sub-furnace body caused by temperature changes or vibration, ensuring the sealing and stability of the connection between the two connected sub-furnace bodies. At the same time, since both the upper and lower heat insulation frames are filled with silicon carbide sand, they have good heat insulation performance, which can effectively block the transfer of heat between adjacent sub-furnace bodies, reduce heat loss to the surrounding environment, and improve the heat utilization efficiency of the entire activated carbon regeneration furnace. The upper and lower heat insulation frames are designed as detachable structures for easy replacement, ensuring the reliability of the connection between the two connected sub-furnace bodies.

[0015] Furthermore, the flexible insulation units between two adjacent sub-furnaces are connected by a plug-in groove and a flexible connecting protrusion. The plug-in groove is located at the upper end of the upper insulation frame, and the flexible connecting protrusion is located at the lower end of the lower insulation frame.

[0016] Note: The two adjacent sub-furnace bodies are connected by a plug-in groove and a flexible connecting convex frame, which can compensate for the displacement and deformation of the sub-furnace bodies caused by temperature changes or vibration, and ensure the sealing and stability of the connection between the two connected sub-furnace bodies.

[0017] Furthermore, the outer wall of the flexible connecting convex frame is provided with a sealing strip, which is made of high-temperature resistant silicone rubber.

[0018] Note: When the flexible connecting protrusion of the sub-furnace body at the upper end is connected to the insertion groove of the sub-furnace body at the lower end, the sealing strip can fill the tiny gap between the flexible connecting protrusion and the insertion groove, effectively preventing internal gas from leaking into the surrounding environment and avoiding environmental pollution. At the same time, it also ensures the stability of the gas environment inside the sub-furnace body, which is conducive to the activated carbon regeneration reaction.

[0019] The beneficial effects of this utility model are:

[0020] This utility model's flexible-connected modular activated carbon regeneration furnace, in use, employs several interconnected sub-furnaces from top to bottom to repeatedly heat the activated carbon powder. This results in a longer flow path for the activated carbon powder within the furnace, allowing for more thorough contact with the heating plates, thus achieving more uniform heating, improving heating efficiency, and ensuring the quality of activated carbon regeneration. Furthermore, the flexible insulation unit connecting adjacent sub-furnaces compensates for displacement and deformation caused by temperature changes or vibrations, ensuring the sealing and stability of the connection points. Simultaneously, each sub-furnace contains a gradually narrowing feed channel with a spiral stirring rod of varying pitch within each channel, which gathers the activated carbon powder, allowing it to move more precisely towards the outlet, reducing dispersion during transport. This also ensures a consistent feeding speed while increasing the pushing pressure at the outlet, guaranteeing the smooth ejection of activated carbon powder into the next sub-furnace, preventing blockages in the pipes, and ensuring the continuity of the entire regeneration process.

Detailed Implementation

[0024] Example 1: As Figure 1 , 2As shown, a modular activated carbon regeneration furnace with flexible connection includes three sub-furnace bodies 1 arranged from top to bottom and equipped with heating plates 10 inside, a spiral conveying unit 2 disposed in each sub-furnace body 1, a drive unit 3 connected to the spiral conveying unit 2, and a flexible heat insulation unit 4 disposed on each pair of sub-furnace bodies 1. The heating plates 10 and the drive unit 3 adopt existing technologies. For example, the heating plates 10 can be existing microwave heating plates, and the drive unit 3 uses existing rotary motors, which are TD series AC synchronous motors.

[0025] The upper and lower ends of the sub-furnace body 1 are provided with staggered material inlets 11 and material outlets 12. Between two adjacent sub-furnace bodies 1, the material outlet 12 of the upper sub-furnace body 1 and the material inlet 11 of the lower sub-furnace body 1 are connected by a metal corrugated pipe 13. The side wall of the sub-furnace body 1 is provided with an exhaust pipe 14.

[0026] The flexible heat insulation unit 4 includes an upper heat insulation frame 40 located at the upper end of the sub-furnace body 1 and a lower heat insulation frame 41 located at the lower end of the sub-furnace body 1. The flexible heat insulation units 4 between two adjacent sub-furnace bodies 1 are interlocked with each other. The flexible heat insulation units 4 between two adjacent sub-furnace bodies 1 are interlocked through an insertion groove 42 and a flexible connecting protrusion 43. The insertion groove 42 is located at the upper end of the upper heat insulation frame 40, and the flexible connecting protrusion 43 is located at the lower end of the lower heat insulation frame 41. The two adjacent sub-furnace bodies 1 are connected by the insertion groove 42 and the flexible connecting protrusion 43, which can compensate for the displacement and deformation of the sub-furnace body 1 caused by temperature changes or vibration, and ensure the sealing and stability of the connection part of the two connected sub-furnace bodies 1.

[0027] Both the upper heat insulation frame 40 and the lower heat insulation frame 41 are filled with silicon carbide sand (commercially available product). Both the upper heat insulation frame 40 and the lower heat insulation frame 41 are detachable structures. The flexible connecting protrusion 43 of the sub-furnace body 1 at the upper end and the insertion groove 42 of the sub-furnace body 1 at the lower end are flexibly connected to ensure the sealing and stability of the connection part of the two connected sub-furnace bodies 1. At the same time, since both the upper heat insulation frame 40 and the lower heat insulation frame 41 are filled with silicon carbide sand, they have good heat insulation performance, which can effectively block the transfer of heat between adjacent sub-furnace bodies 1, reduce heat loss to the surrounding environment, and improve the heat utilization efficiency of the entire activated carbon regeneration furnace. The upper heat insulation frame 40 and the lower heat insulation frame 41 are set as detachable structures, which makes it easy to replace them and ensures the connection reliability of the two connected sub-furnace bodies 1.

[0028] The outer wall of the flexible connecting protrusion 43 is provided with a sealing strip 430. The sealing strip 430 is made of high-temperature resistant silicone rubber. When the flexible connecting protrusion 43 of the sub-furnace body 1 at the upper end is connected to the insertion groove 42 of the sub-furnace body 1 at the lower end, the sealing strip 430 can fill the tiny gap between the flexible connecting protrusion 43 and the insertion groove 42, effectively preventing internal gas from leaking into the surrounding environment and avoiding environmental pollution. At the same time, it also ensures the stability of the gas environment inside the sub-furnace body 1, which is conducive to the activated carbon regeneration reaction.

[0029] Each sub-furnace body 1 is provided with a guide channel 15 with a gradually decreasing opening. The discharge port 11 and the outlet 12 pass through the guide channel 15 respectively. The spiral conveying unit 2 includes a spiral stirring rod 20 provided in the guide channel 15, a rotating gear 21 connected to the spiral stirring rod 20, and a transmission chain 22 for connecting each rotating gear 21. The drive unit 3 drives one of the rotating gears 21 to rotate. By setting the guide channel 15 with a gradually decreasing opening along the charcoal powder conveying direction, the charcoal powder can be heated more fully in the channel. At the same time, it can play a gathering role for the charcoal powder, so that the charcoal powder moves more accurately towards the outlet 12, reducing the dispersion of the charcoal powder during the transmission process. The rotating gear 21 and the transmission chain 22 both adopt existing technologies. For example, the rotating gear 21 adopts the existing cylindrical gear, and the transmission chain 22 adopts the existing toothed chain.

[0030] The pitch of the stirring blades on the spiral stirring rod 20 decreases sequentially, with the largest pitch on the stirring blades on the side of the discharge port 11 and the smallest pitch on the stirring blades on the side of the discharge port 12. The variable pitch spiral stirring rod 20 ensures the feeding speed while increasing the pushing pressure of the charcoal powder at the discharge port 12, ensuring that the charcoal powder can be smoothly pushed out and enter the next sub-furnace body 1, preventing the charcoal powder from clogging the pipes, and ensuring the continuity of the entire regeneration process.

[0031] The following are the steps for using a flexible, modular activated carbon regeneration furnace as described in this embodiment:

[0032] S1. The activated carbon powder is added to the corresponding feed channel 15 through the corresponding discharge port 11 on the uppermost sub-furnace body 1. At this time, the heating plate 10 is started to heat the activated carbon powder in the feed channel 15. The drive unit 3 drives the rotating gear 21 connected to it to rotate, while the other rotating gears 21 rotate synchronously under the action of the transmission chain 22. At this time, the spiral stirring rod 20 located in the uppermost sub-furnace body 1 rotates, causing the activated carbon powder to move towards the discharge port 12 until it falls into the second sub-furnace body 1 through the discharge port 11 connected to the discharge port 12 through the metal corrugated pipe 13.

[0033] S2. After the charcoal powder falls into the second sub-furnace body 1, it continues to fall into the corresponding material guide channel 15. The heating plate 10 is used to reheat the charcoal powder in the material guide channel 15. The spiral stirring rod 20 located in the sub-furnace body 1 rotates in a certain direction, causing the charcoal powder to move towards the discharge port 12 until it falls into the third sub-furnace body 1 through the discharge port 11 connected to the discharge port 12 through the metal corrugated pipe 13.

[0034] S3. After the charcoal powder falls into the third sub-furnace 1, repeat step S1 to complete the third heating of the charcoal powder. Finally, the generated activated carbon falls through the discharge port 12 at the bottom of the third sub-furnace 1 and is collected.

[0035] S4. During the processing of steps S1-S3, the flexible connecting protrusion 43 of the sub-furnace body 1 at the upper end and the insertion groove 42 of the sub-furnace body 1 at the lower end are flexibly connected, which can compensate for the displacement and deformation of the sub-furnace body 1 caused by temperature changes or vibration, and ensure the sealing and stability of the connection part of the two connected sub-furnace bodies 1. The gas generated in each sub-furnace body 1 is discharged through the corresponding exhaust pipe 14.
