Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection equipment, and in particular to an activated carbon regeneration and wastewater coordinated treatment device. Background Art

[0002] In modern industrial and domestic wastewater treatment, activated carbon, with its powerful adsorption properties, has become a crucial medium for removing impurities and pollutants from wastewater. Activated carbon regeneration and wastewater co-treatment devices are becoming increasingly widespread. These devices, through the adsorption of harmful substances in wastewater by activated carbon and the regeneration of saturated activated carbon, achieve resource recycling and purify wastewater to meet discharge standards, playing a key role in environmental protection.

[0003] Currently, most existing activated carbon regeneration and wastewater co-treatment systems use manual or semi-automatic methods to replace and regenerate the activated carbon. During the wastewater treatment process, when the activated carbon reaches saturation, it must be manually removed from the filter and transferred to a regeneration device for heating and regeneration. After regeneration is complete, it must be manually reloaded into the filter. This operation method not only consumes a large amount of manpower and time, but also results in significant activated carbon loss during frequent manual operations, resulting in low activated carbon utilization and making it difficult to ensure the continuity and efficiency of wastewater treatment.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0045] Reference Figures 1 to 9 The present invention provides an embodiment: an activated carbon regeneration and wastewater coordinated treatment device, including a rake furnace 1, a wastewater treatment cylinder 4 is fixedly connected to the outside of the rake furnace 1, and an input pipe 5 is provided on the top of the wastewater treatment cylinder 4. The input pipe 5 realizes the function of introducing wastewater into the cylinder shell 41 of the wastewater treatment cylinder 4.

[0046] The wastewater treatment cartridge 4 includes a cartridge shell 41, the inner wall of which is fixedly connected a drainage ring 42. The drainage ring 42 is funnel-shaped, with an arc-shaped stepped inner wall. The bottom opening radius of the drainage ring 42 is smaller than the top radius of the activated carbon filter plate 432. The drainage ring 42 guides the wastewater downward, allowing it to smoothly enter the activated carbon filter plate 432 of the filter 43 within the cartridge shell 41. The inner wall of the cartridge shell 41 is provided with a filter 43, the outer side of which is provided with a flip member 44. The inner wall of the cartridge shell 41 is fixedly connected to a reset member 45. The upper and lower ends of the outer shell 41 are respectively provided with an inlet valve 46 and a discharge valve 47.

[0047] The filter 43 includes a movable ring 431. When the weight of the activated carbon increases, the movable ring 431 moves together with the activated carbon filter plate 432, driving other related parts to move, such as driving the transmission shaft 441 to make the gear 442 move downward synchronously. The inner side of the movable ring 431 is fixedly connected to the activated carbon filter plate 432. The activated carbon filter plate 432 is used to carry activated carbon particles, so that the wastewater and the activated carbon particles are fully in contact, thereby achieving adsorption and filtration of impurities in the wastewater. The top of the activated carbon filter plate 432 is fixedly connected to two fixed piles 433. The adjacent ends of the two fixed piles 433 rotate It is connected to a flip door 434, and a torsion spring 435 is provided between the flip door 434 and the fixed pile 433. During the flipping process of the filter 43, the flip door 434 flips outward under the action of gravity to provide a channel for the discharge of the adsorption-saturated activated carbon. The torsion spring 435 deforms when the flip door 434 is opened, storing elastic potential energy, and providing power for the subsequent resetting of the flip door 434. A material guide groove 436 is provided on the outer side of the activated carbon filter plate 432 and the movable ring 431. The material guide groove 436 allows the adsorption-saturated activated carbon to slide smoothly out of the activated carbon filter plate 432.

[0048] The flip member 44 includes two rotating shafts, which are respectively fixedly connected to the two sides of the movable ring 431, and the other end of the rotating shaft is fixedly connected to a gear 442. Two tooth plates 443 are fixedly connected to the inside of both sides of the cylindrical shell 41, and two limit plates 444 are fixedly connected to the inside of both sides of the cylindrical shell 41. Tooth grooves are provided at the upper and lower ends of the tooth plate 443. The outer side of the gear 442 is meshed with the tooth grooves, and the number of tooth grooves is one-third of the number of teeth on the outer side of the gear 442. The outer side of the gear 442 contacts the inner side of the limit plate 444. The gear 442 moves downward under the drive of the movable ring 431, and meshes and rotates with the tooth grooves on the tooth plate 443 when reaching the bottom. The relationship between the number of tooth grooves and the number of teeth of the gear 442 is used to make the gear 442 rotate a certain angle, thereby driving the movable ring 431 and the activated carbon filter plate 432 to flip. A sealing plate 445 is rotatably connected to the outer side of the rotating shaft, and a movable cavity 446 is opened inside the cylindrical shell 41. The top and bottom of the sealing plate 445 are both slidably connected inside the movable cavity 446. The sealing plate 445 slides in the movable cavity 446 in the cylindrical shell 41, thereby playing a sealing role in preventing wastewater leakage during the flipping process of the filter 43.

[0049] The reset member 45 includes a fixed ring 451, the outer side of the fixed ring 451 is fixedly connected to the inner side of the cylindrical shell 41, and both ends of the fixed ring 451 are fixedly connected to a sleeve 452, a spring is provided inside the sleeve 452, and the inner side of the sleeve 452 is slidably connected to a telescopic rod 454, and the top of the telescopic rod 454 is rotatably connected to a rotating pile 455, and the top of the rotating pile 455 is fixedly connected to the bottom of the movable ring 431. The spring in the reset member 45 provides elastic force. When the activated carbon particles are not saturated with adsorption, the initial position of the movable ring 431 and the activated carbon filter plate 432 is maintained. When the weight of the activated carbon particles increases after adsorption, the elastic force is overcome to realize the downward movement of the movable ring 431 and the activated carbon filter plate 432. After the activated carbon is discharged, the telescopic rod 454 pushes the movable ring 431 upward under the action of the spring in the sleeve 452 to reset the filter 43.

[0050] The feed valve 46 includes a valve body 461, the outer side of the valve body 461 is fixedly connected to the outside of the cylindrical shell 41, and a feed block 462 is provided inside the valve body 461. The trapezoidal slope of the feed block 462 facilitates the drainage of the regenerated activated carbon particles on the top of the material receiver 2 into the top of the activated carbon filter plate 432. The inner side of the valve body 461 is slidably connected to a bin door 463, and the outer wall of the bin door 463 is fixedly connected to a stop block 464. The bin door 463 slides open when it is subjected to the pressure transmitted by the stop block 464, so that the regenerated activated carbon particles on the top of the material receiver 2 can be poured back into the top of the activated carbon filter plate 432 under the drainage action of the feed block 462.

[0051] The discharge valve 47 includes a valve body 471, the outer side of which is fixedly connected to the outside of the cylinder shell 41. A discharge block 472 is provided inside the valve body 471. The discharge block 472 has a trapezoidal slope shape that facilitates the sliding of adsorption-saturated activated carbon into the bottom cavity of the material receiver 2. The inner side of the valve body 471 is slidably connected to a chamber door 473, the outer wall of which is fixedly connected to a stopper 474, and the outer wall of the chamber door 473 is fixedly connected to a leakproof plate 475. The chamber door 473 slides open when subjected to pressure transmitted by the stopper 474, allowing the adsorption-saturated activated carbon to be discharged. After the activated carbon is discharged, it closes under the action of the elastic reset shaft, and the leakproof plate 475 further prevents leakage. The feed block 462 and the discharge block 472 are both trapezoidal sloped in shape, with the inclined surface of the feed block 462 facing the inside of the cylinder shell 41 and the inclined surface of the discharge block 472 facing the outside of the cylinder shell 41. Elastic reset shafts are provided between the two sides of the gate 1 463 and the inner side of the valve body 1 461 , as well as between the two sides of the gate 2 473 and the inner side of the valve body 2 471 . The elastic reset shafts enable the gate 1 463 and the gate 2 473 to reset and close under corresponding conditions.

[0052] A material receiver 2 is provided at the top of the rake furnace 1. The material receiver 2 receives the regenerated activated carbon from the output hopper. On the one hand, it can be introduced into the top of the activated carbon filter plate 432 through the feed valve 46. On the other hand, it plays a role in connecting various components to ensure a smooth circulation process of activated carbon particles. The top cavity of the material receiver 2 is connected to the feed valve 46, and the bottom cavity of the material receiver 2 is connected to the discharge valve 47, and is connected to the heating and regeneration cavity of the rake furnace 1. The output end of the rake furnace 1 is provided with a screw feeder 3. The screw feeder 3 transports the activated carbon particles output from the rake furnace 1 to the output hopper. An output hopper is provided on the top of the screw feeder 3. The output hopper receives the activated carbon particles transported by the screw feeder 3 and introduces them into the material receiver 2. The bottom of the output hopper is connected to the top of the material receiver 2. The shape of the discharge port of the output hopper is the same as the shape of the cavity at the top of the material receiver 2, so as to avoid leakage of activated carbon.

[0053] Working Principle: Wastewater enters the shell 41 of the wastewater treatment cartridge 4 through the inlet pipe 5. Because the drainage ring 42 is funnel-shaped and has a stepped, arc-shaped inner wall, the wastewater flows down along the drainage ring 42. This allows the wastewater to enter the activated carbon filter plate 432 of the filter 43 in the shell 41. The wastewater continues to flow downward, coming into contact with the activated carbon, and the filtration process begins. During this process, impurities in the wastewater are adsorbed and filtered out by the activated carbon.

[0054] As the filtration proceeds, the activated carbon particles gradually become saturated with adsorption. At this time, due to the saturation of the activated carbon adsorption, the weight of the activated carbon particles on the entire activated carbon filter plate 432 increases, thereby driving the entire movable ring 431 and the activated carbon filter plate 432 to overcome the elastic force of the reset spring 453 and move downward, thereby driving the gear 442 to move downward synchronously through the transmission shaft 441, and when it reaches the bottom, it engages and rotates with the teeth on the tooth plate 443. Because the number of teeth is one-third of the number of teeth on the outer side of the gear 442, the gear 442 rotates a certain angle, driving the movable ring 431 and the activated carbon filter plate 432 to flip. At the same time, since the sealing plate 445 slides in the movable cavity 446, it plays a sealing role to prevent wastewater leakage. During the flipping process, the flip door 434 between the fixed piles 433 flips outward under the action of gravity to facilitate the discharge of the adsorption-saturated activated carbon and causes the torsion spring 435 to deform.

[0055] The adsorption-saturated activated carbon slides out of the guide trough 436, and the flipping of the movable ring 431 generates downward pressure on the block 2 474, thereby driving the bin door 2 473 of the discharge valve 47 to slide open, so that the activated carbon particles slide out to the bottom cavity of the receiver 2 through the trapezoidal slope of the discharge block 472, and fall into the interior of the rake furnace 1, and are heated and regenerated in its heating and regeneration cavity to remove impurities adsorbed on the activated carbon and restore its adsorption capacity. The heated and regenerated activated carbon particles enter the screw feeder 3 through the output end of the rake furnace 1, and the screw feeder 3 transports the activated carbon particles to the output hopper, and then enters the receiver 2 through the output hopper, completing a cycle. After the activated carbon is discharged, due to the reduction in weight of the entire filter 43, the telescopic rod 454 of the reset member 45 pushes the movable ring 431 upward under the action of the spring in the sleeve 452, so that the filter 43 is reset, and the movable ring 431 no longer squeezes the second stopper 474, so that the second door 473 is closed under the action of the elastic reset shaft, and the filter 43 is turned over again to maintain horizontality through the action of the toothed plate 443 and the gear 442. Moreover, since the overall weight is lighter than the initial state, the entire filter 43 is further It continues to move upward, thereby flipping in the opposite direction through the action of the tooth groove at the top of the tooth plate 443, so that the movable ring 431 squeezes the stop block 464 again, thereby opening the bin door 463, so that the regenerated activated carbon on the top of the material receiver 2 is poured back into the top of the activated carbon filter plate 432 under the drainage action of the feed block 462, and due to the increase in gravity, the filter 43 moves downward and flips again, and maintains a balanced state with the elastic force of the return spring 453, so that the filter 43 remains in a horizontal state until the next activated carbon particle adsorption is saturated.
