[0002] At present, the main method for regenerating activated carbon to restore its adsorption capacity is to heat it to a certain high temperature for activation. This heating method is effective for decomposing almost all organic matter and is widely used in industrial production of activated carbon regeneration.

The production quality of rotary kilns is easy to control, and the tail gas can be recycled and treated, which is more environmentally friendly.

[0003] In the prior art, activated carbon has a wide range of uses. In some usage scenarios, there may be a certain amount of moisture in the activated carbon after use, which leads to a long time for the regeneration process of the saturated activated carbon, resulting in additional energy waste. Furthermore, the activated carbon regeneration furnace in the prior art does not have a pretreatment process for the activated carbon. The activated carbon may clump after use in some scenarios, resulting in additional processing links in the active regeneration link, causing unnecessary burden.

The rotary furnace 7 can be rotatably fixed in the cylindrical cavity of the outer tube 1, and the two are coaxially arranged horizontally. A plurality of heating electrodes 14 are evenly arranged in the circumferential direction of the cavity between the rotary furnace 7 and the outer tube 1. The pretreatment cover plate 2 is fixedly connected to the outer wall of the top end of the outer tube 1, and the transfer box cover 3 is fixedly connected to the same side of the pretreatment cover plate 2 and the outer tube 1, which is used to connect the pretreatment cover plate 2 and the outer tube 1; the bottom of the cavity inside the pretreatment cover plate 2 is fixedly connected to a heat-conducting tube 12, one end of the heat-conducting tube 12 extends into the transfer box cover 3 and is connected to the conveying pipeline 10, and the other end is fixedly connected to the side wall of the pretreatment cover plate 2, and a spiral conveying rod 8 is coaxially arranged in the inner cavity of the heat-conducting tube 12. The cavity formed between the pretreatment cover plate 2 and the heat-conducting tube 12 is a heat-conducting cavity, and the heat-conducting cavity is sealed. The conveying pipeline 10 is in an arc shape, one end of which is connected to the heat-conducting cylinder 12, and the other end is open downward, and an inclined material guide plate 11 is arranged below. The upper end of the material guide plate 11 is fixedly connected to the inner wall of the transfer box cover 3, and the lower end extends to the internal cavity of the rotary furnace 7. The upper surface of the material guide plate 11 is a curved surface structure, which is convenient for conveying activated carbon and preventing the activated carbon from falling. The transfer box cover 3 is connected to the rotary furnace 7.

[0029] A convex ring 71 is provided at one end of the rotary furnace 7 close to the transfer box cover 3 to prevent the activated carbon from scattering to the outside of the rotary furnace 7 when it falls to the rotary furnace 7 through the guide plate 11, thereby improving the reliability of the overall structure of the device; the end of the rotary furnace 7 away from the transfer box cover 3 is the material removal end, and an end cover 13 is fixedly connected to the material removal end, and a one-way gas valve is installed on the end cover 13 for discharging the gas inside the rotary furnace 7.

[0030] The top of the pre-treatment cover plate 2 away from the transfer box cover 3 is fixedly connected with an airtight feed assembly 4, and a crushing assembly 9 is arranged in the rectangular feed channel where the airtight feed assembly 4 is connected to the heat-conducting cylinder 12, and the spiral conveying rod 8, the crushing assembly 9, and the rotary furnace 7 are respectively connected to the transmission assembly 6. The support frame 5 is arranged vertically to support the transmission assembly 6; the lower end of the support 15 is fixedly connected to the transmission assembly 6, and the upper end is fixedly connected to the lower end of the airtight feed assembly 4, and is used to support the airtight feed assembly 4.

[0031] An exhaust pipe 21 is provided on the upper surface of the pretreatment cover plate 2 near the airtight feed assembly 4, and the exhaust pipe 21 is connected to the heat conduction cavity to discharge the gas in the heat conduction cavity for subsequent treatment. An exhaust hole 72 is provided on the inner wall of the rotary furnace 7, and a mesh grid is arranged on the exhaust hole 72, so that the gas in the rotary furnace 7 can enter the cavity between the rotary furnace 7 and the outer cylinder 1, and the activated carbon will not fall out through the exhaust hole 72. One end of the air inlet pipe 73 is fixed in the cavity between the rotary furnace 7 and the outer cylinder 1, and the other end is fixedly connected to one end of the heat conduction cavity near the transfer box cover 3, and is connected to the heat conduction cavity, so that the gas in the rotary furnace 7 can enter the heat conduction cavity through the exhaust hole 72 and the air inlet pipe 73. The air inlet pipe 73 and the exhaust pipe 21 are arranged at both ends of the heat conduction cavity, so that the gas in the rotary furnace 7 can pass through the entire heat conduction cavity and then be discharged, and the waste heat resources can be more fully utilized.

[0032] like Figure 2 As shown, the airtight feed assembly 4 includes: an airtight feed assembly cover plate 41, a star-shaped discharge valve core 42, and an inert gas pipeline 43. The airtight feed assembly cover plate 41 is an integrated structure with a hollow interior, the upper part of which is funnel-shaped, the middle part is a sphere, a star-shaped discharge valve core 42 is installed inside the sphere, the lower part extends horizontally as an activated carbon storage buffer, and the bottom is inserted into the heat-conducting cylinder 12 as a feed channel. The inert gas pipeline 43 is installed between the middle and lower parts of the airtight feed assembly cover plate 41, and is used to pass inert gas to ensure that the gas in the furnace does not leak to the external space, and the external gas does not enter the furnace in large quantities, so as to avoid the combustion of activated carbon in the furnace and the occurrence of safety hazards. At the same time, the inert gas can also be used as a carrier gas for the regeneration of activated carbon.

[0033] The transmission assembly 6 includes: a motor base 61, a driving motor 62, a first gear 63, a second gear 64, a third gear 65, a first pulley 66, a second pulley 67, and a transmission belt 68. The motor base 61 is fixedly mounted on the top of the support frame 5, and the lower end of the support column 15 is fixedly connected to the upper surface of the motor base 61; the driving motor 62 is fixedly mounted on the lower surface of the motor base 61, and the first gear 63 is locked to the output end of the driving motor 62 through a coupling; the second gear 64 is fixedly sleeved on the outer wall of the rotary furnace 7, and the second gear 64 is meshed with the first gear 63; the third gear 65 is fixedly connected to the end of the spiral conveying rod 8 away from the transfer box cover, and the third gear 65 is meshed with the first gear 63. Figure 4 As shown, the first pulley 66 is fixedly connected to the rotating shaft of the third gear 65 and rotates synchronously with the third gear 65; the second pulley 67 is rotatably fixedly connected to the outer wall of the feed channel of the airtight feeding component 4, and its rotating shaft is connected to the crushing component 9; the first pulley 66 and the second pulley 67 are connected by a transmission belt 68, and the second pulley 67 rotates synchronously with the first pulley 66.

[0034] like Figure 5As shown, the crushing assembly 9 includes: an eccentric shaft 91, a crushing block 92, a limiting shaft 93, a limiting groove 94, and a steel plate 95. The eccentric shaft 91 is rotatably fixedly connected to the rotating shaft of the second pulley 67, and the eccentric shaft 91 and the rotating shaft of the second pulley 67 are in an eccentric state; the middle of the top of the crushing block 92 is rotatably mounted on the eccentric shaft 91, and the two ends of the bottom of the crushing block 92 are in an arc state; a strip-shaped limiting groove 94 is provided in the middle of the bottom end of the crushing block 92, and the middle of the rectangular feeding channel connecting the airtight feeding assembly 4 and the heat-conducting cylinder 12 is fixedly connected to the limiting shaft 93, and the limiting groove 94 is movably sleeved on the outside of the limiting shaft 93, so that the crushing block 92 can only move within a limited range. The inner wall of the feed channel on both sides of the crushing block 92 is provided with a corrugated steel plate 95. The activated carbon is usually granular. The corrugated steel plate 95 can reduce the wear of the activated carbon on the inner wall of the airtight feed assembly 4 during the crushing process, and prevent the activated carbon from being too crushed after crushing.

[0035] In the actual production process, some high-humidity saturated activated carbon will clump after use. When large particles or activated carbon with caking are processed, they need to be broken up first to achieve better results. Activated carbon is put into the airtight feeding device cover plate 41 through the funnel-shaped inlet. The activated carbon enters the feeding channel after passing through the star-shaped discharge valve core 42. At the same time, the drive motor 62 is started to drive the first gear 63 to rotate, and the third gear 65 meshing with the first gear 63 rotates synchronously, thereby driving the first pulley 66 and the second pulley 67 to rotate. The eccentric shaft 91 installed on the rotating shaft of the second pulley 67 also rotates synchronously. Since the rotating shaft of the second pulley 67 is not coaxial with the eccentric shaft 91, the eccentric shaft 91 rotates during the rotation. , the position also changes continuously; the crushing block 92 sleeved on the eccentric shaft 91 moves synchronously, and due to the cooperation of the limiting groove 94 and the limiting shaft 93 provided at the bottom of the crushing block 92, the crushing block 92 continuously performs reciprocating circular swinging motion. Through the continuous swinging of the crushing block 92, the activated carbon entering between the inner wall of the feed channel and the crushing block 92 is strongly squeezed, so that large particles or agglomerated activated carbon are broken, and large particles of activated carbon are prevented from entering the subsequent device, thereby improving the subsequent regeneration and activation treatment effect of the activated carbon.

[0036] After passing through the crushing assembly 9, the activated carbon enters the heat-conducting tube 12. Since the spiral conveying rod 8 is fixedly connected to the rotating shaft of the third gear 65, the spiral conveying rod 8 rotates synchronously with the third gear 65, driving the activated carbon in the inner cavity of the heat-conducting tube 12 to be transported axially toward the transfer box cover 3. In this process, the flue gas generated during the high-temperature activation of the activated carbon in the rotary furnace 7 enters the heat-conducting cavity through the exhaust hole 72 and the air inlet pipe 73, and the flue gas and the heat-conducting tube 12 are heat-conducted, so that the activated carbon with lower temperature and higher humidity in the heat-conducting tube 12 is preheated and dried, thereby realizing full utilization of the heat energy of the flue gas; the flue gas is finally discharged directly from the exhaust pipe 21, or discharged after passing through the flue gas treatment device.

[0037] After the activated carbon enters the conveying pipeline 10 from the heat-conducting cylinder 12 under the push of the spiral conveying rod 8, it enters the rotary furnace 7 for high-temperature heating and calcination under the guidance of the guide plate 11 below the conveying pipeline 10. Since the second gear 64 is meshed with the first gear 63, the rotary furnace 7 rotates synchronously under the drive of the second gear 64 fixed thereon, so that the activated carbon in the rotary furnace 7 is always in a state of continuous tumbling motion, and the activated carbon is evenly heated under the action of the heating electrode 14. As the heating time increases, the activated carbon can be quickly fully activated. The one-way air valve design on the end cover 13, while balancing the internal pressure of the regeneration heating furnace of the saturated activated carbon, serves as an auxiliary and backup channel for the exhaust of the flue gas generated during the high-temperature activation of the activated carbon, to avoid malfunction of the regeneration heating furnace of the saturated activated carbon when the exhaust pipe 21 is blocked.

[0038] The transmission assembly 6 of the present invention synchronously drives the crushing assembly 9, the spiral conveying rod 8, and the rotary furnace 7 to operate, realizing the multiple driving effects of the single motor power. The present invention utilizes the waste heat of the flue gas generated during the high-temperature activation of activated carbon, shortens the processing time of activated carbon regeneration, and maximizes the utilization of resources.

[0039] Those skilled in the art can understand that the above are only preferred examples of the invention and are not intended to limit the invention. Although the invention is described in detail with reference to the above examples, those skilled in the art can still modify the technical solutions recorded in the above examples or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, etc. made within the spirit and principle of the invention shall be included in the protection scope of the invention.
