Description

Technical Field

[0001] The present invention relates to the technical field related to the regeneration of waste activated carbon, and in particular to a drying and regeneration device for solid waste activated carbon. Background Art

[0002] Waste activated carbon refers to activated carbon that has been used, but waste activated carbon can also restore its adsorption capacity through regeneration treatment so that it can be reused. However, before high-temperature treatment of the waste activated carbon, it is necessary to first remove moisture and volatile substances on the surface of the waste activated carbon.

[0003] Chinese patent document CN219356266U discloses a hazardous waste activated carbon resource regeneration treatment device. The device is provided with a stirring dragon inside the drying cylinder, which is driven by a transmission motor to reciprocate forward and reverse, so as to stir and transport the activated carbon to avoid the accumulation of the activated carbon. An electric telescopic rod is hinged at the bottom of the drying cylinder. Through the lifting and lowering of the electric telescopic rod, one end of the drying cylinder is made to rise and fall, so as to cooperate with the rotation of the stirring dragon, so that the activated carbon is always transported upward to avoid the accumulation of the activated carbon, and the effect of drying the activated carbon evenly is achieved. However, there are still the following shortcomings:

[0004] The waste activated carbon in the device of this scheme will fall when it is transported to a high place, and the device of this scheme is repeatedly up and down and stirred. In addition, the gradually drying waste activated carbon lacks the lubrication and buffering of water, and the friction between them increases. The impact force generated during the collision is more likely to cause the waste activated carbon to crack and break, thereby reducing the quality of the activated carbon after regeneration.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1

[0038] like Figure 1 - Figure 3As shown, this embodiment discloses a solid waste activated carbon drying and regeneration treatment device, including a box body 1, a drying mechanism 2 for preliminary drying is provided at the upper left end of the box body 1, the right part of the drying mechanism 2 extends to the inner cavity of the box body 1, an exhaust fan unit 6 is provided at the right end of the drying mechanism 2, and a ventilation pipe group 8 for filtering and guiding is provided at the air outlet end of the exhaust fan unit 6, a U-shaped shielding frame 9 for preventing the waste activated carbon from falling is provided in the middle and upper part of the inner cavity of the box body 1, and the inner side of the upper horizontal part of the U-shaped shielding frame 9 is a woven mesh structure that does not affect the blowing of airflow, a conveying mechanism 11 for conveying the waste activated carbon is provided in the middle of the inner cavity of the box body 1, and the conveying mechanism The second 11 is located at the lower side of the U-shaped shielding frame 9 and is close to the vertical part of the U-shaped shielding frame 9 and does not touch each other. The lower part of the left side wall of the box body 1 is provided with an open groove 1 that horizontally penetrates the side wall of the box body 1. The inner side of the open groove 1 is provided with a heat preservation curtain 3 for blocking heat loss. A conveying mechanism 10 is provided at the lower part of the inner cavity of the box body 1, and the left part of the conveying mechanism 10 passes through the open groove 1 and extends to the outside of the box body 1. The conveying mechanism 10 and the conveying mechanism 2 11 are both ordinary belt conveyors. This is a simple prior art, so it will not be described in detail. The front and rear ends of the box body 1 are jointly provided with an exhaust pipe 4 for discharging exhaust gas;

[0039] In addition, if Figure 5 and Figure 6 As shown, the exhaust pipe connected to the exhaust end of the exhaust unit 6 extends to the inner side of the drying mechanism 2 to extract the hot air inside the drying mechanism 2, wherein the exhaust pipe is in the shape of a round stool, the stool part is located outside the outer cylinder 21, connected to the exhaust fan, and the stool leg part extends to the inner side of the outer cylinder 21, and does not contact with the spiral conveying blade 26, gear one 27 and gear two 29. Since this is a simple pipeline connection, it will not be described in detail;

[0040] It can be seen from this that during the high-temperature drying process of the waste activated carbon by the drying mechanism 2, the exhaust unit 6 is also extracting the hot air in the drying mechanism 2, and then blowing the dehumidified hot air to the conveying mechanism 11 through the ventilation pipe group 8, thereby increasing the ambient temperature and air flow rate in the box 1. After the preliminary drying, the waste activated carbon will be dispersed and fall onto the conveying mechanism 11, and then during the transportation process by the conveying mechanism 11, the waste activated carbon will also pass through the blowing area of ​​the ventilation pipe group 8 to facilitate secondary air drying of the waste activated carbon, thereby improving the drying efficiency of the waste activated carbon without damaging the waste activated carbon. Finally, the waste activated carbon leaves the box 1 through the conveying mechanism 10 and enters the subsequent high-temperature regeneration device.

[0041] Specifically, Figure 4 and Figure 5As shown, the drying mechanism 2 includes an outer cylinder 21, and the outer cylinder 21 is located at the lower part of the box body 1 and is provided with an open groove 2 that vertically penetrates the side wall of the outer cylinder 21 for discharging materials. A heating inner cylinder 23 is provided on the inner side of the outer cylinder 21, and an electric heating wire is installed on the inner wall of the side wall of the heating inner cylinder 23. A plurality of discharge grooves 211 that vertically penetrate the side wall of the heating inner cylinder 23 for early discharge are evenly provided at the right end of the heating inner cylinder 23. The left inner wall of the discharge groove 211 and the left inner wall of the open groove 2 are located in the same vertical plane, so that part of the waste activated carbon can leave in advance and be dispersed and laid on the conveying mechanism 2 11 to reduce accumulation. A plurality of connecting rods 210 are evenly provided at the right end of the heating inner cylinder 23, and the right ends of the plurality of connecting rods 210 are commonly provided with an inner gear ring 28, and the inner gear ring 28 is rotatably connected to the outer cylinder 21. A gear 1 27 is provided on the upper part of the right inner wall of the outer cylinder 21, and the gear 1 27 is meshed with the inner gear ring 28.

[0042] Specifically, a motor 22 is provided at the middle of the left end of the outer cylinder 21, and a rotating rod 24 is provided at the output end of the motor 22 through a coupling, and the right end of the rotating rod 24 extends to the inner side of the outer cylinder 21 and is rotatably connected to the right inner wall of the outer cylinder 21, and a gear 29 is provided at the right part of the outer surface of the rotating rod 24, and the gear 29 is meshed with the gear 1 27, and a spiral conveying blade 26 and a plurality of stirring mechanisms 25 for stirring the waste activated carbon are provided on the outer surface of the rotating rod 24, and the stirring mechanism 25 and the spiral conveying blade 26 do not contact each other, and the spiral conveying blade 26 and the inner walls of the outer cylinder 21 and the heating inner cylinder 23 are close to each other and do not contact each other;

[0043] As can be seen from the above, after the waste activated carbon is poured into the outer cylinder 21, the motor 22 controls the rotating rod 24 and the spiral conveying blade 26 to rotate, and pushes the waste activated carbon toward the direction of the box body 1. In this process, the rotating rod 24 will also control the inner gear ring 28 to rotate in the opposite direction to the spiral conveying blade 26 through the meshing gear 2 29 and the gear 1 27. Then, the inner gear ring 28 drives the heating inner cylinder 23 to rotate slowly through the connecting rod 210. In this way, through the slow rotation of the heating inner cylinder 23 and the spiral conveying blade 26, the waste activated carbon is always in an active state, avoiding local overheating of the waste activated carbon and affecting the quality after regeneration.

[0044] Specifically, Figure 6 As shown, a mounting groove 4 212 is provided inside the rotating rod 1 24, a fixing rod 213 is horizontally provided inside the mounting groove 4 212, and the right end of the fixing rod 213 penetrates the side wall of the rotating rod 1 24 and is fixedly connected to the right inner wall of the outer cylinder 21, that is, the fixing rod 213 will rotate relative to the rotating rod 1 24;

[0045] Specifically, the stirring mechanism 25 includes a rotating rod 252, the outer surface of which is provided with a support cylinder, and the end of the support cylinder close to the rotating rod 24 is fixedly connected to the rotating rod 24, the end of the rotating rod 252 close to the rotating rod 24 extends to the inner side of the fixed rod 213, and a bevel gear set 251 is provided between the end of the rotating rod 252 close to the fixed rod 213 and the outer surface of the fixed rod 213, and the end of the rotating rod 252 away from the rotating rod 24 is provided with a stirring blade 253 for dispersing the waste activated carbon, the stirring blade 253 and the inner wall of the heating inner cylinder 23 are close to each other and do not contact each other, and the outer surface of the stirring blade 253 is provided with a high temperature resistant rubber sleeve for protecting the waste activated carbon;

[0046] In addition, in order to prevent the waste activated carbon from being over-extruded and broken during movement, the stirring mechanism 25 should be located in the middle of the impeller interval of the spiral conveying blade 26 to avoid affecting the normal pushing of the material by the spiral conveying blade 26, and the filling rate of the waste activated carbon inside the heating inner cylinder 23 should be less than 50%, so that when the stirring blade 253 rotates to push the waste activated carbon, the waste activated carbon has enough space to move;

[0047] As can be seen from the above, when the rotating rod 24 drives the rotating rod 252 to rotate, the bevel gear set 251 will also control the rotation of the rotating rod 252 and the stirring blade 253 due to the relative rotation between the fixed rod 213 and the rotating rod 24, so as to increase the heating area of ​​the waste activated carbon through gentle, small and multiple flipping, improve the drying effect of the waste activated carbon, and ensure the quality of the regenerated waste activated carbon.

[0048] In addition, the reason for slowly stirring the wet waste activated carbon, in addition to the above-mentioned effects, is that the presence of water provides a certain lubrication and buffering effect between the activated carbon particles, thereby reducing the friction between the particles. The impact force during collision can also be buffered to a certain extent, which can reduce the risk of waste activated carbon breakage.

[0049] Specifically, Figure 3 As shown, the ventilation pipe group 8 includes a connecting pipe 81 fixedly connected to the air outlet end of the exhaust unit 6, a dehumidification pipe 82 is provided at the right end of the connecting pipe 81, a plurality of hollow filter plates filled with quicklime desiccant bags are provided on the inner side of the dehumidification pipe 82 to remove water vapor in the hot air flow, and a comb-shaped blowing pipe 83 for blowing the hot air flow toward the waste activated carbon is provided at the right end of the dehumidification pipe 82.

[0050] Therefore, the specific implementation of this embodiment is:

[0051] After the waste activated carbon is poured into the outer cylinder 21, the motor 22 controls the rotating rod 1 24 and the spiral conveying blade 26 to rotate, and pushes the waste activated carbon toward the box body 1. In this process, the rotating rod 1 24 controls the inner gear ring 28 to rotate in the opposite direction of the spiral conveying blade 26 through the meshing gear 2 29 and the gear 1 27. Then the inner gear ring 28 drives the heating inner cylinder 23 to rotate slowly through the connecting rod 210, and rotates relative to the fixed rod 213. Then the bevel gear set 251 is used to control the stirring blade 253 to rotate slowly, and the wet waste activated carbon is stirred, so that the waste activated carbon is always in an active state. The heating area of ​​the waste activated carbon is increased by a gentle, small amount and multiple flipping method, and the drying effect of the waste activated carbon is improved to avoid local overheating of the waste activated carbon and affect the quality after regeneration.

[0052] At the same time, the exhaust fan group 6 is also extracting the hot air in the drying mechanism 2, and then blowing the dehumidified hot air to the conveying mechanism 11 through the ventilation pipe group 8, so as to increase the ambient temperature and air flow rate in the box body 1. After the preliminary drying, the waste activated carbon will be dispersed and dropped onto the conveying mechanism 11 through the discharge trough 211 and the opening trough 2. Then, during the transportation by the conveying mechanism 11, the waste activated carbon will also pass through the blowing area of ​​the comb-shaped blowing pipe 83 to facilitate the secondary air drying of the waste activated carbon, thereby improving the drying efficiency of the waste activated carbon without damaging the waste activated carbon. Finally, the waste activated carbon leaves the box body 1 through the conveying mechanism 10 and enters the subsequent high-temperature treatment.

[0053] Embodiment 2

[0054] This embodiment adds a driving mechanism 5 and a pushing mechanism 7 on the basis of the first embodiment, so as to improve the air drying effect of the waste activated carbon, and reduce the dust in the box 1, reduce the dust escape, and endanger the health of workers. Figure 1 and Figure 3 As shown, a driving mechanism 5 for controlling the operation of a push mechanism 7 by utilizing the falling of waste activated carbon is provided at the left part of the inner cavity of the box body 1, and a mounting groove 1 is provided at the left side of the inner side of the front side wall and the rear side wall of the box body 1;

[0055] Specifically, Figure 7 As shown, the driving mechanism 5 includes a second rotating rod 51 rotatably connected to the left part of the inner cavity of the box body 1, and the front end and the rear end of the second rotating rod 51 extend into the installation groove 1 on the same side respectively, and a sleeve 52 is provided in the middle of the outer surface of the second rotating rod 51, and a plurality of blade assemblies 53 are evenly provided on the outer surface of the sleeve 52;

[0056] Specifically, Figure 8As shown, the blade assembly 53 includes a mounting box 531 and a counterweight plate 533. The mounting box 531 is fixedly connected to the sleeve 52. The front inner wall and the rear inner wall of the mounting box 531 are both provided with a wave-shaped groove 532. The end of the counterweight plate 533 close to the sleeve 52 is provided with a slide plate 534 slidably connected to the mounting box 531. The front end and the rear end of the slide plate 534 away from the counterweight plate 533 are both provided with a slide bar 535, and the two slide bars 535 are respectively slidably connected to the two wave-shaped grooves 532 on the same side.

[0057] It can be seen from the above that when part of the waste activated carbon in the heating inner cylinder 23 falls off in advance through the discharge chute 211, in addition to facilitating the dispersion and laying of part of the waste activated carbon on the conveying mechanism 2 11 to reduce accumulation, it is also used to force the driving mechanism 5 to rotate by impacting the blade assembly 53. When the blade assembly 53 rotates to the lower side of the sleeve 52, the counterweight plate 533 will slide down under the action of its own gravity, and then the sliding rod 535 is used to slide in the wavy groove 532 to make the counterweight plate 533 shake during the downward movement, so as to reduce the adhesion of the waste activated carbon and reduce omissions.

[0058] Furthermore, when the blade assembly 53 rotates to the right side of the rotating rod 51 and is in a horizontal state, the mounting box 531 is located on the left side of the discharge trough 211, and the counterweight plate 533 is located directly below the discharge trough 211, so as to prevent the waste activated carbon from falling into the connection part between the counterweight plate 533 and the mounting box 531, affecting the resetting of the counterweight plate 533.

[0059] Specifically, Figure 2 , Figure 3 and Fig. 9 As shown, a push mechanism 7 for flattening the waste activated carbon is provided at the upper left portion of the U-shaped shielding frame 9, and the push mechanism 7 includes a U-shaped mounting frame 71 fixedly connected to the U-shaped shielding frame 9, and the left end of the U-shaped mounting frame 71 is an inclined surface structure for reducing the accumulation of waste activated carbon, so as to reduce the accumulation of waste activated carbon, and the distance between the two vertical parts of the U-shaped mounting frame 71 is greater than the maximum width of the vertical part of the comb-shaped blowing pipe 83, and a slide groove 72 is provided at the upper left end of the U-shaped mounting frame 71, and a bidirectional screw 73 is provided at the inner right portion of the slide groove 72, and the front end and rear end of the bidirectional screw 73 are The two-way screw 73 and the part of the rotating rod 51 located in the same mounting groove 1 are provided with a belt transmission mechanism. The left end of the U-shaped mounting frame 71 is provided with a pushing plate 74 for pushing the waste activated carbon, and the lower end of the pushing plate 74 and the inner top wall of the opening of the U-shaped shielding frame 9 are located in the same horizontal plane. The upper right end of the pushing plate 74 is provided with a limiting plate slidably connected to the slide groove 72. The right part of the limiting plate is sleeved on the outer side of the two-way screw 73 and is threadedly connected to the two-way screw 73.

[0060] From the above, it can be seen that when the rotating rod 2 51 rotates due to the impact of the blade assembly 53, it will also drive the bidirectional screw 73 to rotate through the belt transmission mechanism, and then the bidirectional screw 73 controls the pushing plate 74 to move back and forth through the limit plate, thereby pushing away some of the waste activated carbon that is piled together, so that the conveying mechanism 2 11 can normally convey the waste activated carbon to the inner side of the opening of the U-shaped shielding frame 9.

[0061] Specifically, Fig.10 As shown, the U-shaped mounting frame 71 has two mounting grooves on the left and right sides thereof, and the two mounting grooves are connected to the slide groove 72. A speed increasing gear transmission assembly 75 is provided on the inner side of the mounting groove 2. The speed increasing gear transmission assembly 75 is composed of a plurality of gears meshing with each other and a shaft for connection. This is a simple prior art, so it will not be described in detail. The speed increasing gear transmission assembly 75 is connected to the bidirectional screw 73.

[0062] Specifically, Fig. 9 - Fig.11 As shown, three one-way valves 710 are provided at one end of the two vertical parts of the U-shaped mounting frame 71 that are away from each other, ventilation cavities are provided inside the two vertical parts of the U-shaped mounting frame 71, and the ventilation cavities are connected to the exhaust pipe 4 through the one-way valves 710, and three opening grooves three horizontally penetrating the side wall of the U-shaped mounting frame 71 are provided on one side wall of the two ventilation cavities that are close to each other, and a filter screen 79 for filtering dust is provided on the inner side of the opening groove three, and three air extraction mechanisms 77 are provided on the inner side of the ventilation cavity, and the three air extraction mechanisms 77 respectively block the opening groove three on the same side, and a rotating rod three 76 for controlling the simultaneous operation of the three air extraction mechanisms 77 is provided horizontally on the inner side of the ventilation cavity, and three reciprocating spiral grooves 78 are provided on the outer surface of the rotating rod three 76, and the left end of the rotating rod three 76 extends into the mounting groove two on the same side and is connected to the speed increasing gear transmission assembly 75;

[0063] Specifically, Fig.11As shown, the air extraction mechanism 77 is composed of a piston plate 771, a grinding plate 772, a sealing plate 775 and a T-shaped baffle plate 778. The right end of the grinding plate 772 is a curved structure, which is used to cooperate with the inclined surface of the triangular plate 776 to push the triangular plate 776 into the installation groove three 773. A connecting rod is provided between the ends of the piston plate 771 and the grinding plate 772 that are close to each other. The piston plate 771 and the grinding plate 772 are sleeved on the outer side of the rotating rod three 76 and are slidably connected to the rotating rod three 76. The grinding plate 772 is threadedly connected to the rotating rod three 76 through the reciprocating spiral groove 78. The moving distance of the piston plate 771 is less than the shortest distance between two adjacent reciprocating spiral grooves 78, so that the rotating rod three 76 rotates to control the movement of the grinding plate 772, and then the grinding plate 772 drags the piston plate 771 through the connecting rod to rotate. The surface of rod three 76 moves to create a vacuum and extract the gas in the box body 1. The sealing plate 775 is slidably connected to the inner side of the ventilation cavity to block the opening groove three. The sealing plate 775 is provided with a mounting groove three 773 that horizontally penetrates the left end of the sealing plate 775 at one end close to the grinding plate 772. A triangular plate 776 is provided on the inner side of the mounting groove three 773. A spring one is provided between the end of the triangular plate 776 away from the grinding plate 772 and the inner wall of the mounting groove three 773. A T-shaped baffle plate 778 is fixedly connected to the ventilation cavity. The T-shaped baffle plate 778 is located on the left side of the sealing plate 775. The right part of the horizontal part of the T-shaped baffle plate 778 is a triangular structure that matches the triangular plate 776. A spring two 777 is provided between the vertical part of the T-shaped baffle plate 778 and the end of the triangular plate 776 that is close to each other.

[0064] As can be seen from the above, when the bidirectional screw 73 rotates, it will also control the rotating rod 3 76 to rotate at a faster speed through the speed-increasing gear transmission assembly 75, and then the rotating rod 3 76 controls the leftward movement of the grinding plate 772 through the reciprocating spiral groove 78. The grinding plate 772 controls the sealing plate 775 to move to open the opening groove 3 by pushing the triangular plate 776, and at the same time pulls the piston plate 771 to move leftward through the connecting rod to create a vacuum and extract the airflow in the box body 1. In this process, the dust mixed in the airflow will be intercepted by the filter 79 When the grinding plate 772 and the sealing plate 775 are about to move the maximum distance, the triangular plate 776 will be pushed into the installation groove three 773 due to the contact with the horizontal part of the T-shaped baffle 778, and then the sealing plate 775 will return to the initial position in advance under the action of the spring two 777, and re-seal the opening groove three. When the grinding plate 772 starts to move back, the excess gas in the ventilation cavity will be discharged through the one-way valve 710 and the exhaust pipe 4.

[0065] Therefore, the specific implementation of this embodiment is:

[0066] When the waste activated carbon leaves the drying mechanism 2 and falls onto the conveying mechanism 2 11, it will also drive the rotating rod 2 51 to rotate through the impact blade assembly 53, and then the rotating rod 2 51 will drive the bidirectional screw 73 to rotate through the belt transmission mechanism. The bidirectional screw 73 controls the pushing plate 74 to move back and forth through the limit plate to push away some of the waste activated carbon piled together, so that the conveying mechanism 2 11 can normally convey the waste activated carbon to the inner side of the opening of the U-shaped shielding frame 9, and controls the rotating rod 3 76 to rotate at a faster speed through the speed increase gear transmission assembly 75. Then the rotating rod 3 76 controls the left movement of the grinding plate 772 through the reciprocating spiral groove 78, and the grinding plate 772 controls the sealing plate 775 by pushing the triangular plate 776. Move to open the opening slot three, while pulling the piston plate 771 to the left through the connecting rod to create a vacuum and extract the airflow in the box body 1. In this process, the dust mixed in the airflow will be intercepted by the filter screen 79, thereby reducing the dust in the box body 1 and further reducing the dust overflow, protecting the health of the staff. When the grinding plate 772 and the sealing plate 775 are about to move the maximum distance, the triangular plate 776 will be pushed into the installation slot three 773 due to contact with the inclined surface of the horizontal part of the T-shaped baffle 778, and then the sealing plate 775 will return to the initial position in advance under the action of the spring two 777, and re-block the opening slot three. When the grinding plate 772 starts to move back, the excess gas in the ventilation cavity will be discharged through the one-way valve 710 and the exhaust pipe 4.
