Description

Technical Field

[0001] This utility model relates to the field of activated carbon granulation, and more specifically, to an automated phosphoric acid-based wood-based activated carbon granulation device. Background Technology

[0002] Phosphoric acid-based activated carbon is a type of activated carbon prepared from wood materials such as fruit shells and bamboo processing residues using phosphoric acid as an activating agent. In order to improve the material performance and process adaptability, the phosphoric acid-based activated carbon powder needs to be mixed with binder and water in a certain proportion and then granulated using a granulation device. The granulated activated carbon can significantly improve the adsorption capacity of macromolecular organic matter.

[0003] Existing phosphoric acid-based wood activated carbon granulation devices have some problems in actual operation. For example, the molding and granulation equipment for producing wood granular activated carbon using the phosphoric acid method (publication number CN215711800U) can cut the material by using the fit between the cutter and the extrusion nozzle to avoid splashing of columnar material, but its functionality is relatively limited and it cannot perform efficient and uniform mixing of raw materials. Furthermore, in actual operation, it cannot perform efficient and uniform drying of the granulated activated carbon particles in the first instance. Therefore, the activated carbon particles are prone to breakage or even shattering during subsequent transfer. Therefore, we have made improvements and proposed an automated phosphoric acid-based wood activated carbon granulation device. Utility Model Content

A feeding groove is opened at the bottom side of the conveying cylinder, and a discharge groove is opened at the top side of the conveying cylinder. A forming hole is opened through the bottom of the conveying cylinder. A spring and a limiting rod are welded to the conveying cylinder, and a cutting blade is welded to the spring. The limiting rod is slidably connected to the cutting blade.

[0007] As a preferred technical solution of this application, a first cover plate is attached to the top of the first feed frame, and a second cover plate is attached to the top of the second feed frame. Both the first cover plate and the second cover plate are made of magnetic material. The first feed frame and the second feed frame are symmetrically distributed on both sides of the processing box. The guide pipe corresponds to the second feed frame one by one. The guide pipe is attached to the turntable. The through holes are symmetrically distributed on both sides of the turntable.

[0008] As a preferred technical solution of this application, the stirring rod and the scraper are evenly distributed on the turntable, the stirring rod corresponds one-to-one with the first gear, the scraper is in contact with the inner wall of the processing box, the bottom of the processing box is funnel-shaped, the inner bottom surface of the processing box is flush with the bottom surface of the feed trough, and the feed trough and the discharge trough are symmetrically distributed on both sides of the conveying cylinder.

[0009] As a preferred technical solution of this application, the forming holes are distributed at equal angles at the bottom of the conveying cylinder, the bottom end face of the conveying cylinder is in contact with the cutting blade, the length and width of the cutting blade are both greater than the diameter of the conveying cylinder, and the limiting rods are symmetrically distributed on both sides of the cutting blade.

[0010] As a preferred technical solution of this application, a second servo motor is welded and fixed on the bottom surface of the fixed box, a push plate and a second gear are welded and fixed on the output shaft of the second servo motor, the push plate is generally elliptical, a third gear is meshed on the second gear, a first air guide pipe is welded and fixed on the third gear, and the first air guide pipe is rotatably connected to the bottom surface inside the fixed box.

[0011] As a preferred technical solution of this application, a support plate is welded and fixed on the first air guide pipe, and positioning rods are welded and fixed on both sides of the top of the support plate. Positioning grooves are opened on both sides of the bottom of the collection frame, and the positioning rods are engaged and connected in the positioning grooves.

Furthermore, the continuous rotation of the collection frame can ensure uniform drying of each wood-based activated carbon granule, thereby promoting the curing of the binder, enhancing the granule strength, reducing breakage during subsequent transportation, and increasing the versatility of the granulation device.

[0023] like Figures 1-7As shown, this embodiment proposes an automated phosphoric acid-based wood-based activated carbon granulation device, including a base 1 and a collection frame 31.

The limiting rod 22 is slidably connected to the cutting blade 23. Example

[0024] The solution in Example 1 will be further described below with reference to its specific working method. like Figures 1-3 As shown, in a preferred embodiment, based on the above method, a first cover plate 5 is attached to the top of the first feed frame 4, and a second cover plate 7 is attached to the top of the second feed frame 6. Both the first cover plate 5 and the second cover plate 7 are made of magnetic material. The first feed frame 4 and the second feed frame 6 are symmetrically distributed on both sides of the processing box 3. The guide pipe 8 corresponds one-to-one with the second feed frame 6. The guide pipe 8 is attached to the turntable 10. The through holes 11 are symmetrically distributed on both sides of the turntable 10. By utilizing the continuous rotation of the turntable 10, the through holes 11 on both sides can be intermittently aligned with the guide pipes 8 on both sides, thereby realizing the intermittent feeding of adhesive and water. This avoids the problem of the adhesive and water only contacting part of the activated carbon powder prepared by the phosphoric acid method during the one-time delivery of adhesive and water, resulting in low subsequent mixing efficiency and poor mixing effect.

[0025] like Figures 2-5As shown, in a preferred embodiment, based on the above method, the stirring rods 12 and scrapers 15 are evenly distributed at an angle on the turntable 10. The stirring rods 12 correspond one-to-one with the first gears 13, and the scrapers 15 are in contact with the inner wall of the processing box 3. The bottom of the processing box 3 is funnel-shaped, and the bottom surface of the inner end of the processing box 3 is flush with the bottom surface of the feed trough 18. The feed trough 18 and the discharge trough 19 are symmetrically distributed on both sides of the conveying cylinder 17. By utilizing the meshing of the first gear 13 and the internal gear 14, each stirring rod 12 can be driven to rotate automatically during the revolution, thereby enabling comprehensive and uniform stirring of the activated carbon powder prepared by the phosphoric acid method inside the processing box 3. This allows for efficient and uniform mixing of the activated carbon powder with the binder and water, ensuring material uniformity and enhancing the bonding force of the particles.

[0026] like Figure 2 , Figure 4 , Figures 6-9 As shown, in a preferred embodiment, based on the above method, the forming holes 20 are further distributed at equal angles at the bottom of the conveying cylinder 17. The bottom end face of the conveying cylinder 17 is in contact with the cutting blade 23. The length and width of the cutting blade 23 are both greater than the diameter of the conveying cylinder 17. The limiting rods 22 are symmetrically distributed on both sides of the cutting blade 23. A second servo motor 24 is welded and fixed to the bottom end face of the fixed box 2. A push plate 25 and a second gear 26 are welded and fixed to the output shaft of the second servo motor 24. The push plate 25 is generally elliptical. A third gear 27 is meshed and connected to the second gear 26. A first air guide pipe 28 is welded and fixed to the third gear 27. The first air guide pipe 28 is rotatably connected to the bottom end face inside the fixed box 2. The second servo motor 24 can drive the push plate 25 to rotate continuously. Combined with the limiting of the limiting rod 22 and the elastic force of the spring 21, the cutting blade 23 can be pushed to perform automatic and stable reciprocating motion, thereby automatically cutting the material extruded from the forming holes 20 to obtain phosphoric acid-based wood activated carbon columnar particles.

[0027] like Figure 2 , Figure 8 and Figure 9As shown, in a preferred embodiment, based on the above method, a support plate 29 is welded and fixed to the first air guide pipe 28. Positioning rods 30 are welded and fixed to the top two sides of the support plate 29. Positioning grooves 32 are opened on the bottom two sides of the collection frame 31. The positioning rods 30 are engaged and connected in the positioning grooves 32. A guide block 33 is welded and fixed inside the collection frame 31. The guide block 33 is generally conical. Both the guide block 33 and the collection frame 31 are made of mesh material. An air pump 34 is installed and fixed at the bottom of the base 1. A second air guide pipe 35 is connected to the air pump 34. One end of the second air guide pipe 35 is sculpted. The first air guide pipe 28 is connected to the bottom of the second air guide pipe 35, and the other end of the second air guide pipe 35 is fixedly connected to the ventilation cylinder 36. The ventilation cylinder 36 is bolted with a filter screen plate 37, a dehumidifying screen plate 38 and an electric heating tube 39. The fixed box 2 is connected to an exhaust pipe 40 and a door panel is installed on the fixed box 2. The collection frame 31 can stably collect the formed phosphoric acid activated carbon particles. At the same time, driven by the air pump 34, combined with the filter screen plate 37, the dehumidifying screen plate 38 and the electric heating tube 39, the phosphoric acid activated carbon particles can be efficiently dried using filtered and dried high-temperature gas.

[0028] Specifically, when using this automated phosphoric acid-based wood-based activated carbon granulation device: First, the operator can lift the first cover plate 5 at the top of the first feed frame 4 and the second cover plate 7 at the top of the second feed frame 6 to open the first feed frame 4 and the second feed frame 6 on both sides. Then, the operator can transport the wood-based activated carbon powder prepared by the phosphoric acid method into the processing box 3 through the first feed frame 4, and at the same time, quantitatively transport the required binder and water into the second feed frames 6 on both sides to complete the feeding work. At this time, under the drive of the first servo motor 9, the output shaft can drive the turntable 10 and the screw rod 16 to rotate simultaneously. At this time, the screw rod 16 feeds upward. Under the rotation of the turntable 10, it can drive each stirring rod 12 to revolve, and then drive the corresponding first gear 13 to move synchronously. At this time, under the meshing action of the first gear 13 and the internal gear 14, it can drive the internal gear 14 to rotate automatically during the revolution, and then drive each stirring rod 12 to rotate automatically during the revolution. Meanwhile, under the continuous rotation of the turntable 10, the through holes 11 on both sides can be intermittently aligned with the guide pipes 8 on both sides, thereby enabling the intermittent feeding of adhesive and water. Combined with the stirring of each stirring rod 12, the adhesive and water can be evenly mixed in the activated carbon powder in various places. Under the continuous rotation of the screw rod 16, the activated carbon powder can enter through the feed chute 18 at the upper end of the conveying cylinder 17, and be conveyed upward by the screw rod 16 and discharged through the discharge chute 19. This process is repeated to continuously circulate the material at the bottom upward, avoiding the accumulation of material at the bottom which can easily lead to uneven mixing, and further improving the mixing efficiency and mixing effect of the material. During the material mixing process, the second servo motor 24 can drive the push plate 25 to rotate and push the cutting blade 23 to block the forming hole 20 at the bottom of the conveying cylinder 17 to prevent the material from falling. After the material is mixed evenly, the first servo motor 9 can drive the screw rod 16 to rotate in the opposite direction. At this time, the screw rod 16 feeds downward, and can feed through the feeding trough 18 and convey the material downward. It is then granulated through each forming hole 20. At this time, the output shaft of the second servo motor 24 can also drive the turntable 10 to rotate. By using the movement of each scraper 15, the material attached to the inner wall of the processing box 3 can be automatically scraped and cleaned. During the extrusion process of the material through each forming hole 20, the second servo motor 24 drives the push plate 25 to rotate continuously. Combined with the limiting rod 22 and the elastic force of the spring 21, the cutting blade 23 can be driven to perform automatic and stable reciprocating motion, thereby automatically cutting the material extruded from the forming hole 20 to obtain phosphoric acid wood activated carbon columnar granules. Subsequently, the granules automatically fall into the collection frame 31, and under the guidance of the inclined surface of the guide block 33 in the middle part, the falling of the granules is buffered. Meanwhile, driven by the air pump 34, outside air can be drawn in through the second air pipe 35 and the ventilation tube 36, and transported to the collection frame 31 through the first air pipe 28. During the air extraction process, the phosphoric acid activated carbon particles can be efficiently dried through the filtration of the filter plate 37, the dehumidification of the dehumidification plate 38, and the heating of the electric heating tube 39. During the operation of the second servo motor 24, the output shaft can drive the second gear 26 to rotate synchronously. The meshing third gear 27 can drive the first air pipe 28 to rotate stably. At this time, under the positioning action of the positioning rod 30 and the collection frame 31, the collection frame 31 can be driven to rotate stably through the support plate 29, thereby ensuring the uniform drying of each activated carbon particle, which can promote the curing of the adhesive, enhance the particle strength, reduce breakage during subsequent transportation, and the exhaust gas generated during drying can be transported to the exhaust gas treatment equipment for purification through the exhaust pipe 40. After the granulation process is completed, the staff only needs to fix the door panel on box 2 to lift the collection frame 31 upwards and detach it from the tray 29 and positioning rod 30. Then the staff can transfer the activated carbon granules. Similarly, the staff only needs to place the used collection frame 31 on the tray 29 and insert the positioning slot 32 into the positioning rod 30 to complete the positioning of the collection frame 31 and ensure the stability of the subsequent working state of the collection frame 31.
