Description

Technical Field

[0001] This utility model relates to the field of activated carbon recovery technology, specifically to an activated carbon solvent recovery device. Background Technology

[0002] Activated carbon has a highly developed pore structure and a large specific surface area, and it has a strong adsorption capacity for a variety of molecules, making it an excellent adsorbent. It is currently widely used in the adsorption and purification of industrial waste gas and VOCs. However, if used activated carbon is not recycled, it will not only be a waste of resources, but also cause secondary pollution to the environment. Therefore, from both economic and environmental perspectives, the regeneration of activated carbon is of great significance.

[0003] The existing technology has the following problems:

[0004] 1. In the existing activated carbon solvent recovery device, the use of stirring to promote contact between activated carbon particles and the recovery solution makes the activated carbon particles prone to breakage during stirring, resulting in some activated carbon particles failing to meet the standards for reuse.

[0005] 2. In the operation of existing activated carbon solvent recovery devices, when dehydrating activated carbon particles, centrifugal devices are often used to remove the water between the activated carbon particles. However, when the equipment starts or stops, the centrifugal force gradually decreases, causing the activated carbon particles that are attached to the inner wall of the centrifugal device to lose support and collide with each other, resulting in the problem of activated carbon particles being damaged. Utility Model Content

[0006] This invention provides an activated carbon solvent recovery device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] An activated carbon solvent recovery device includes a recovery body, a motor is fixedly connected to the bottom of the recovery body, and a waterproof electric telescopic frame is fixedly connected to the output end of the motor. The outer wall of the waterproof electric telescopic frame is rotatably connected to the inner wall of the recovery body, and a recovery component is fixedly connected to the output end of the waterproof electric telescopic frame.

[0009] A feed inlet is provided on the top of one side of the outer wall of the recycling body, and several baffles are fixedly connected to the inner wall of the recycling body near the feed inlet. A drain trough is provided at the bottom of one side of the inner wall of the recycling body, and a drain pipe is fixedly connected to one end of the inner wall of the drain trough.

[0010] A further improvement of the present invention is that: the recycling component includes a support block fixedly connected to the output end of the waterproof electric telescopic frame, and a support shaft rotatably connected to the outer wall of each support block. A limit box is fixedly connected to one end of the outer wall of each of the multiple support shafts, and a filter plate is rotatably connected to the inner wall of the limit box. A swing blade is fixedly connected to the bottom of the filter plate. A limit filter plate is fixedly connected to the outer wall of the limit box on the side near the filter plate, and a storage box is fixedly connected to the top of the limit filter plate. An airbag is installed on the inner wall of the storage box.

[0011] A further improvement of the present invention is that: an air pump is fixedly connected to the top of the recycling body, and a telescopic air guide pipe is fixedly connected to the output end of the air pump; one end of the telescopic air guide pipe is fixedly connected to an air distribution plate, and the bottom of the air distribution plate is fixedly connected to the top of the support block.

[0012] A further improvement of this utility model is that: the output end of the air distribution plate is fixedly connected to an exhaust pipe, and one end of the exhaust pipe is evenly distributed and fixedly connected to the top of the box.

[0013] A further improvement of this utility model is that: two annular limiting frames are fixedly connected to the outer walls of the storage box, and the outer walls of the two annular limiting frames are slidably connected to both ends of the outer wall of the filter plate, and one side of the outer wall of the two annular limiting frames is fixedly connected to the outer wall of the limiting box.

[0014] A further improvement of this utility model is that: an installation box is slidably connected to the end of the outer wall of the filter plate away from the limiting box, and a closing plate is installed on the inner wall of the installation box; the top of one side of the outer wall of the installation box is fixedly connected to one end of the outer wall of the storage box; and the end of the outer wall of the installation box away from the storage box is fixedly connected to the end of the outer wall of the two annular limiting frames away from the limiting box.

[0015] A further improvement of this utility model is that: a waterproof electric telescopic rod is fixedly connected to one end of the outer wall of the support block near the support shaft, and a push block is fixedly connected to the output end of the waterproof electric telescopic rod.

[0016] A further improvement of this utility model is that a sliding groove is provided at the bottom of the outer wall of the limiting box, and the surface of the sliding groove is slidably connected to one side of the outer wall of the pushing block.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides an activated carbon solvent recovery device. By setting a limiting filter plate on the outer wall of the limiting box near the filter plate, and the diameter of the limiting filter plate is smaller than that of the filter plate, when the filter plate swings, the limiting filter plate limits the activated carbon particles placed on its surface while assisting the activated carbon particles to roll in the recovery solution and rub against each other. This causes impurities attached to the surface of the activated carbon particles to fall off through friction and impact from the recovery solution. This further solves the problem that in traditional activated carbon solvent recovery devices, the stirring method used to promote contact between activated carbon particles and the recovery solution can easily cause the activated carbon particles to break during stirring, resulting in some activated carbon particles not meeting the standards for reuse.

[0019] 2. This utility model provides an activated carbon solvent recovery device. An air bladder presses and fixes the activated carbon particles on the surface of a filter plate. Then, a waterproof electric telescopic frame is activated, moving the support block and filter plate to the top of the baffle plate. The motor is then restarted and rotated, causing the recovery solution adhering between the activated carbon particles to be thrown out by centrifugal force. This further solves the problem in traditional activated carbon solvent recovery devices where, during dehydration, a centrifugal device is often used to remove water from the activated carbon particles. However, when the device starts or stops, the centrifugal force gradually decreases, causing the activated carbon particles adhering to the inner wall of the centrifugal device to lose support and collide with each other, resulting in breakage of the activated carbon particles.

[0035] like Figures 1-5As shown, this utility model provides an activated carbon solvent recovery device, including a recovery body 1. A motor 2 is fixedly connected to the bottom of the recovery body 1, and a waterproof electric telescopic frame 3 is fixedly connected to the output end of the motor 2. The outer wall of the waterproof electric telescopic frame 3 is rotatably connected to the inner wall of the recovery body 1, and a recovery assembly is fixedly connected to the output end of the waterproof electric telescopic frame 3. A feed inlet 4 is provided at the top of one side of the outer wall of the recovery body 1, and several baffles 5 are fixedly connected to the inner wall of the recovery body 1 near the feed inlet 4. A drain trough 6 is provided at the bottom of one side of the inner wall of the recovery body 1, and a drain pipe 7 is fixedly connected to one end of the inner wall of the drain trough 6. The recovery assembly includes a support block 8 fixedly connected to the output end of the waterproof electric telescopic frame 3, and a support shaft 9 rotatably connected to the outer wall of each support block 8. A limit box 10 is fixedly connected to one end of the outer wall of each of the multiple support shafts 9, and a limit box 10 is rotatably connected to the inner wall of the limit box 10. A filter plate 11 is placed, and a swing blade 12 is fixedly connected to the bottom of the filter plate 11. A limiting filter plate 13 is fixedly connected to the outer wall of the limiting box 10 near the side of the filter plate 11, and a storage box 14 is fixedly connected to the top of the limiting filter plate 13. An airbag 15 is installed on the inner wall of the storage box 14. Annular limiting frames 20 are fixedly connected to both sides of the outer wall of the storage box 14, and the outer walls of the two annular limiting frames 20 are slidably connected to both ends of the outer wall of the filter plate 11. One side of the outer wall of the two annular limiting frames 20 is fixedly connected to the outer wall of the limiting box 10. The end of the outer wall of the filter plate 11 away from the limiting box 10 is slidably connected to the mounting box 21, and the inner wall of the mounting box 21 is equipped with a closing plate 22. The top of one side of the outer wall of the mounting box 21 is fixedly connected to one end of the outer wall of the storage box 14, and the end of the outer wall of the mounting box 21 away from the storage box 14 is fixedly connected to the end of the outer wall of the two annular limiting frames 20 away from the limiting box 10.

[0036] During operation, a motor 2 is installed at the bottom of the recycling body 1, and a waterproof electric telescopic frame 3 is installed at the output end of the motor 2. Activating the waterproof electric telescopic frame 3 moves the support block 8 at the output end upwards. Multiple support shafts 9, limit boxes 10, filter plates 11, and swing blades 12, etc., installed on the outer wall of the support block 8, pass through a baffle plate 5 installed at the top of one side of the inner wall of the recycling body 1. An inlet 4 is provided on the outer wall of the recycling body 1 near the baffle plate 5. The closing plate 22 installed on the inner wall of the mounting box 21 is removed through the inlet 4. Activated carbon granules are then fed into the surface of the filter plates 11 through the mounting box 21. Finally, the closing plate 22 is reinstalled on the inner wall of the mounting box 21. At this time, the motor 2 is activated, and the waterproof electric telescopic frame 3 is used to drive the waterproof electric telescopic frame 3. The water-powered telescopic frame 3 and support blocks 8, along with other parts, are used to position the mounting box 21 on the other side at the opening of the inlet 4. This process is repeated to spread activated carbon particles onto the surface of the filter plate 11. The water-powered telescopic frame 3 is then activated again, moving the support blocks 8 and other parts below the baffle plate 5. The recovered solution is then poured into the recovery body 1 through the inlet 4, ensuring it covers the support blocks 8. Multiple support shafts 9 are located on one side of the outer wall of the support blocks 8, and each support shaft 9 has a limit box 10 at one end. The limit box 10 limits the placement of the filter plate 11 on its inner wall. When the motor 2 is restarted, it moves the filter plate 11 intermittently within the recovered solution, centered on the support blocks 8. The filter plate 11 is rotated counterclockwise. A swing blade 12 is installed at the bottom of the filter plate 11. During its movement, the resistance generated between the swing blade 12 and the recovery solution causes the filter plate 11 to rotate slightly within the limiting box 10. This causes the activated carbon particles on the surface of the filter plate 11 to tumble as the filter plate 11 swings. To prevent the activated carbon particles from falling off during tumbling, a limiting filter plate 13 is installed on the outer wall of the limiting box 10 near the filter plate 11. The diameter of the limiting filter plate 13 is smaller than that of the filter plate 11. Thus, when the filter plate 11 swings, the limiting filter plate 13 limits the activated carbon particles on its surface while simultaneously assisting the activated carbon particles in their movement within the recovery solution. The activated carbon particles tumble and rub against each other, causing impurities adhering to their surfaces to fall off through friction and the impact of the recycled solution. A collection box 14 is installed on top of the limiting filter plate 13, and two annular limiting frames 20 are installed on both sides of the outer wall of the collection box 14. These two annular limiting frames 20 limit the ends of the outer wall of the filter plate 11, preventing excessive impact between the oscillating blade 12 and the recycled solution, which would otherwise cause excessive oscillation of the filter plate 11 and the activated carbon particles on its surface to fall off through the gap between the filter plate 11 and the limiting filter plate 13. After the activated carbon particles are cleaned, an air pump 16 inflates the air bladder 15 installed inside the collection box 14, causing the air bladder 15 to expand continuously.The activated carbon particles on the surface of the filter plate 11 are squeezed, and the above operation is repeated to move the filter plate 11 to the top of the baffle plate 5. The closing plate 22 placed in the mounting box 21 is then removed, and the bag is placed over the outer wall of the mounting box 21. At this time, the supporting pivot 9 is used to tilt the limiting box 10, the filter plate 11, the swing blade 12, and other parts as a whole, and the air in the air bag 15 is expelled, causing the activated carbon particles to lose support and slide into the bag along the filter plate 11. This further solves the problem that in traditional activated carbon solvent recovery devices, the stirring method used to promote contact between activated carbon particles and the recovery solution can easily cause the activated carbon particles to break during stirring, resulting in some activated carbon particles not meeting the standards for reuse.

[0037] An air pump 16 is fixedly connected to the top of the recycling body 1, and a telescopic air guide pipe 17 is fixedly connected to the output end of the air pump 16. One end of the telescopic air guide pipe 17 is fixedly connected to an air distribution plate 18, and the bottom of the air distribution plate 18 is fixedly connected to the top of the support block 8. An exhaust pipe 19 is fixedly connected to the output end of the air distribution plate 18, and one end of the exhaust pipe 19 is evenly connected to the top of the storage box 14.

[0038] During operation, an air pump 16 is installed on the top of the recycling body 1. When the air pump 16 is started, air is sent from the telescopic air guide pipe 17 at its output end into the air distribution plate 18. Then, the air distribution plate 18 evenly sends the air through several exhaust pipes 19 at the air output end into the collection box 14, filling the airbag 15 in the collection box 14. The airbag 15 is used to squeeze and fix the activated carbon particles on the surface of the filter plate 11. Then, the waterproof electric telescopic frame 3 is started, moving the support block 8 and the filter plate 11 and other devices to the top of the baffle plate 5. At this time, the motor 2 is started again and rotated, so that the recycled solution attached between the activated carbon particles is thrown out under the action of centrifugal force. This further solves the problem that in the traditional activated carbon solvent recovery device, when dehydrating activated carbon particles, the centrifugal device is often used to throw out the water between the activated carbon particles. However, when the equipment starts or stops, the centrifugal force gradually decreases, causing the activated carbon particles attached to the inner wall of the centrifugal device to lose support and collide with each other, resulting in damage to the activated carbon particles.

[0039] A waterproof electric telescopic rod 23 is fixedly connected to one end of the outer wall of the support block 8 near the support shaft 9, and a push block 24 is fixedly connected to the output end of the waterproof electric telescopic rod 23. A sliding groove 25 is provided at the bottom of the outer wall of the limiting box 10, and the surface of the sliding groove 25 is slidably connected to one side of the outer wall of the push block 24.

[0040] During operation, a waterproof electric telescopic rod 23 is installed on the outer wall of the support block 8 near the support shaft 9. When it is necessary to discharge the activated carbon particles placed on the surface of the filter plate 11, the waterproof electric telescopic rod 23 is activated, and the push block 24 at its output end is disengaged from the slide groove 25 at the bottom of the outer wall of the limit box 10 (the push block 24 never disengages from the contact with the slide groove 25). This causes the limit box 10 to gradually lose support, and the filter plate 11 and other devices to gradually tilt around the support shaft 9, thereby discharging the activated carbon particles in the filter plate 11. When the activated carbon particles are discharged and the next batch is refilled, the waterproof electric telescopic rod 23 is activated, and the push block 24 at its output end pushes the limit box 10 through the slide groove 25 until the filter plate 11 and other devices remain parallel.

[0041] The working principle of this activated carbon solvent recovery device will be explained in detail below.

[0042] like Figures 1-5As shown, a motor 2 is installed at the bottom of the recycling body 1, and a waterproof electric telescopic frame 3 is installed at the output end of the motor 2. The waterproof electric telescopic frame 3 is started and drives the support block 8 installed at the output end to move upward. Multiple support shafts 9, limit boxes 10, filter plates 11, swing blades 12 and other parts installed on the outer wall of the support block 8 pass through the baffle plate 5 installed at the top of one side of the inner wall of the recycling body 1. A feed inlet 4 is set on the side of the outer wall of the recycling body 1 near the baffle plate 5. The closing plate 22 installed on the inner wall of the installation box 21 is removed through the feed inlet 4. Then, activated carbon granules are fed into the surface of the filter plate 11 through the installation box 21. Finally, the closing plate 22 is reinstalled. The inner wall of the mounting box 21 is then installed. Motor 2 is started, and it drives the waterproof electric telescopic frame 3 and support blocks 8, positioning the mounting box 21 on the other side at the opening of the inlet 4. This process is repeated to spread activated carbon particles onto the surface of the filter plate 11. The waterproof electric telescopic frame 3 is then started again, moving the support blocks 8 and other components below the baffle plate 5. The recovered solution is then poured into the recovery body 1 through the inlet 4, ensuring it covers the support blocks 8. Multiple support shafts 9 are located on one side of the outer wall of the support blocks 8, and each support shaft 9 has a limit box 10 at one end. The limit box 10 is used to adjust the position of the support shafts on their inner walls. The filter plate 11 is positioned for limiting. When the motor 2 restarts, it drives the filter plate 11 to rotate intermittently clockwise and counterclockwise around the support block 8 in the recovery solution. By using the oscillating blades 12 at the bottom of the filter plate 11, the resistance generated between the oscillating blades 12 and the recovery solution during the movement of the filter plate 11 causes it to rotate slightly within the limiting box 10. This causes the activated carbon particles on the surface of the filter plate 11 to tumble as the filter plate 11 oscillates. To prevent the activated carbon particles from falling off during tumbling, a limiting filter plate is installed on the outer wall of the limiting box 10 near the filter plate 11. 13. The diameter of the limiting filter plate 13 is smaller than that of the placement filter plate 11. When the placement filter plate 11 swings, the limiting filter plate 13 limits the activated carbon particles placed on its surface while assisting the activated carbon particles to roll in the recovery solution and rub against each other. This causes the impurities attached to the surface of the activated carbon particles to fall off through friction and the impact of the recovery solution. This further solves the problem that in the traditional activated carbon solvent recovery device, the stirring method is used to promote the contact between the activated carbon particles and the recovery solution, which makes the activated carbon particles easy to break during stirring, resulting in some activated carbon particles not meeting the standards for reuse.

[0043] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
