DETAILED DESCRIPTION

[0037] The following is a detailed description of a continuous carbonization tower for the catalytic preparation of activated carbon using phosphoric acid, provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0038] like Figures 1 to 13 As shown, an embodiment of the present invention provides a continuous carbonization tower for the preparation of activated carbon by phosphoric acid catalysis, including a base 1, which is used to fix the entire carbonization tower to the ground to prevent collapse. A shell unit 2 is fixedly connected to the top of the base 1. The shell unit 2 is composed of several tower shells 22 connected in sequence. The outer wall of the lowest tower shell 22 has a discharge port 221, and the top of the uppermost tower shell 22 is fixedly connected to a top shell 21. The top of the top shell 21 has a feed port 211. By splicing several tower shells 22, the user can adjust the height of the carbonization tower according to actual working needs. The feed port 211 and the discharge port 221 are respectively connected to an external screw feeder. A connecting ring plate 23 is fixedly connected to the inner wall of the middle tower shell 22. The inner ring of the connecting ring plate 23 is fixed... A carbonization and activation cylinder 3 is connected to the material. The carbonization and activation processes of the material are carried out inside the carbonization and activation cylinder 3. The top of the carbonization and activation cylinder 3 is connected to the inlet 211, and the bottom of the carbonization and activation cylinder 3 is connected to the inlet of the screw feeder installed on the outlet 221. The material feeding, carbonization, activation and discharge processes are all completed inside the carbonization and activation cylinder 3. A partition plate 31 is fixedly connected to the inner wall of the carbonization and activation cylinder 3 at the corresponding position of the connecting ring plate 23. The partition plate 31 has several uniform partition holes 311. The partition plate 31 is used to divide the inside of the carbonization and activation cylinder 3 into two areas. The upper part of the partition plate 31 is the carbonization area, and the lower part of the partition plate 31 is the activation area. The carbonization area is used to decompose the material at high temperature, so that the material forms an initial carbon skeleton and pore structure. The activation area expands and increases the pore volume of the material through oxidation reaction, thereby improving the adsorption performance. The activation area is a prior art.

[0039] The anti-blocking and shunting device 5 is arranged on the inner wall of one end of the carbonization and activation cylinder 3, and is connected with the carbonization and activation cylinder 3. The anti-blocking and shunting device 5 is used for shunting and preventing blocking of the material to be carbonized. The anti-blocking and shunting device 5 comprises a semicircular spherical shunting ball 51. The diameter of the shunting ball 51 is smaller than the diameter of the top of the carbonization and activation cylinder 3. The gap between the shunting ball 51 and the carbonization and activation cylinder 3 can pass the material. Different diameters of the shunting ball 51 are installed to adapt to different sizes of the material. The bottom end of the outer wall of the shunting ball 51 is uniformly fixed with four connecting rods 52. The shunting ball 51 is fixedly connected to the inner wall of the carbonization and activation cylinder 3 through the four connecting rods 52. Every two adjacent connecting rods 52 are distributed at an angle of 90°. The outer wall of the shunting ball 51 is uniformly connected with a plurality of connecting columns 54 which are annularly and uniformly distributed. Each connecting column 54 is correspondingly connected with a spring material strip 53. When the material passes through, the spring material strip 53 is slightly deformed due to the extrusion of the material, thereby increasing the space for the material to pass through. The anti-blocking and shunting device 5 and the partition plate 31 are connected with the mounting column 8. The outer wall of the mounting column 8 is fixedly connected with the spiral feeding strip 6. The spiral feeding strip 6 has a spiral structure. The two sides of the spiral feeding strip 6 are sealingly connected with the outer wall of the mounting column 8 and the inner wall of the carbonization and activation cylinder 3, respectively. Therefore, the material falling through the anti-blocking and shunting device 5 can only pass through the spiral feeding strip 6. The mounting column 8 is connected with the material adjusting device 9. The mounting column 8 is used for providing mounting positions for the spiral feeding strip 6 and the material adjusting device 9. The outer wall of the material adjusting device 9 is connected with the adjusting spiral strip 7. The material adjusting device 9 is used for adjusting the adjusting spiral strip 7. The material adjusting device 9 drives the adjusting spiral strip 7 to move up and down, so as to adjust the speed of the material passing through the spiral feeding strip 6. When the material is blocked on the spiral feeding strip 6, the reciprocating movement of the adjusting spiral strip 7 can loosen the material, so as to prevent the material from being blocked on the spiral feeding strip 6. The spiral feeding strip 6 and the adjusting spiral strip 7 have spiral structures, and the spiral feeding strip 6 is located above the adjusting spiral strip 7.

[0040] The temperature adjusting device 4 is arranged in the gap between the inner wall of the tower shell 22 and the outer wall of the carbonization and activation cylinder 3.

[0042] The material to be carbonized enters the inlet 211 from the external spiral feeder, falls from the inlet 211 to the pressing cover 55 of the anti-plugging shunt device 5 on the pressing cover 55, and is then guided to the gap between the shunt ball 51 and the carbonization and activation cylinder 3, so as to fall onto the spiral feeding strip 6 through the gap. When there is more material, the material will extrude the elastic material section 531 when passing through the gap between the shunt ball 51 and the carbonization and activation cylinder 3, so that the elastic material section 531 is extruded and deformed, thereby increasing the gap between the shunt ball 51 and the carbonization and activation cylinder 3, facilitating the passage of the material, and the subsequent material falling from the inlet 211 will impact the pressing cover 55, the sliding rod 57 connected to the pressing cover 55 will slide on the sliding groove 59 when the pressing cover 55 is impacted, at this time the edge position of the pressing cover 55 will extrude the driving section 532, the driving section 532 will be displaced downward, and the displacement will drive the elastic material section 531 to vibrate, the blocked material will be loosened by the vibrating elastic material section 531, and when the pressing cover 55 is not impacted by the material, the reset spring 56 will drive the sliding rod 57 to return to the initial position.

[0043] As Figure 2 , Figures 6 to 9As shown, the temperature adjusting device 4 comprises gas heating pipes 43 fixedly connected to the top of the connecting ring plate 23 and a heat uniformizing sleeve 42 sleeved on the outer wall of the carbonization activation cylinder 3, the heat uniformizing sleeve 42 and the gas heating pipes 43 are connected through the flow guide ring sheet 41, the gas heating pipes 43 are used to provide heating temperature for material carbonization, the heat uniformizing sleeve 42 is used to wrap the carbonization area of the carbonization activation cylinder 3, so that a uniform heating area is formed between the heat uniformizing sleeve 42 and the carbonization activation cylinder 3, and the flow guide ring sheet 41 is used to guide the high-temperature gas flow generated by the gas heating pipes 43 into the heat uniformizing sleeve 42; the high-temperature gas flow can be gathered through the heat uniformizing sleeve 42 to directly heat the carbonization activation cylinder 3, and the internal high-temperature gas flow is homogenized through the flow guide spiral sheet 423 to increase the carbonization effect of the material in the carbonization activation cylinder 3; the gas heating pipes 43 are provided in plurality and annularly and uniformly distributed on the top of the connecting ring plate 23, each of the gas heating pipes 43 is connected with a plurality of uniformly distributed spray pipes 431, the spray pipes 431 are inclined toward the heat uniformizing sleeve 42, and the inclination direction of the spray pipes 431 forms an angle of 30° with the axis of the gas heating pipes 43, the two ends of the heat uniformizing sleeve 42 are provided with sealing openings 424 with diameters consistent with the diameter of the carbonization activation cylinder 3, the inner surface wall of the heat uniformizing sleeve 42 is fixedly connected with the flow guide spiral sheet 423, the end of the heat uniformizing sleeve 42 close to the flow guide ring sheet 41 is provided with a plurality of annularly and uniformly distributed import holes 421, the direction of the import holes 421 is consistent with the spiral direction of the flow guide spiral sheet 423, and the outer surface wall of the bottom of the heat uniformizing sleeve 42 is provided with a plurality of uniformly distributed export holes 422; the flow guide ring sheet 41 is connected by two flow gathering segments 412, two flow guide segments 413 and one export segment 414, the bottoms of the two symmetrically distributed flow gathering segments 412 are fixedly connected with the outer surface wall of the heat uniformizing sleeve 42 and the inner surface wall of the tower body shell 22 respectively, the same direction ends of the two flow gathering segments 412 are connected with the flow guide segments 413 respectively, the ends of the two flow guide segments 413 away from the flow gathering segments 412 are fixedly connected through the export segment 414, the outer surface wall of the export segment 414 is fixedly connected with the guide pipe 411 corresponding to the import hole 421, the guide pipe 411 is adapted to the import hole 421, and the high-temperature gas flow is accelerated when passing through the flow gathering segment 412 and entering the flow guide segment 413, the carbonization activation cylinder 3 is isolated from the gas heating pipes 43 through the heat uniformizing sleeve 42, so as to avoid that the gas heating pipes 43 directly act on the outer surface wall of the carbonization activation cylinder 3 and cause the phenomenon of uneven temperature in the carbonization activation cylinder 3, and the temperature in the heat uniformizing sleeve 42 is homogenized through the flow guide spiral sheet 423.

[0044] The nozzle 431 can drive the heated airflow to move towards the guide ring sheet 41 when the combustion is heated. The high-temperature airflow enters between the two converging sections 412 under the impact of the heated airflow of the nozzle 431, and then enters the guide section 413 through the two converging sections 412, and then enters the uniform heating sleeve 42 through the guide pipe 411 and the guide hole 421. Since the high-temperature airflow ejected from the guide pipe 411 is consistent with the rotation direction of the guide spiral sheet 423, the high-temperature airflow rotates and moves along the rotation direction of the guide spiral sheet 423, and finally the high-temperature airflow enters the area where the gas heating pipe 43 is located through the guide hole 422, thereby forming a circulation.

[0045] As shown in Figure 2 、 Figures 10 to 13 , the mounting column 8 is an internally hollow cylindrical structure, and the inside of the mounting column 8 is used to provide a mounting position for the material adjusting device 9. The two ends of the mounting column 8 are fixedly connected to the bottom of the flow dividing ball 51 and the top of the partition plate 31, respectively. The outer wall of the mounting column 8 is provided with four annularly and uniformly distributed first sliding grooves 81, which are used to provide sliding tracks for the first sliding block 95. The inner side of the first sliding groove 81 is provided with a second sliding groove 82 that is in communication with the inside of the mounting column 8. The second sliding groove 82 is used to provide a sliding track for the second sliding block 94. The material adjusting device 9 includes a connecting bearing 92 that is fixedly connected to the inner wall of the mounting column 8.

The surface wall of the spiral feeding strip 6 is provided with adjusting holes 61 at positions corresponding to the adjusting columns 71.

[0046] When it is necessary to adjust the material on the surface of the spiral feeding strip 6, the second sliding block 94 and the first sliding block 95 fixed on the nut seat 93 are driven to reciprocate by the lead screw 91. When the first sliding block 95 is displaced, the adjusting spiral strip 7 fixed on the first sliding block 95 is displaced. When the adjusting spiral strip 7 is displaced, the adjusting columns 71 on the surface of the adjusting spiral strip 7 slide on the adjusting holes 61. The length of the adjusting columns 71 extending on the adjusting holes 61 is adjusted, and the speed of the material on the surface of the spiral feeding strip 6 can be adjusted by the adjusting columns 71.

[0047] The working principle of the technical scheme provided by the present application is as follows: the inlet 211 and the outlet 221 are respectively connected with external screw feeders, the material to be carbonized immersed in phosphoric acid is sent to the inlet 211 by the screw feeder, after the material to be carbonized enters the inlet 211 from the external screw feeder, the material falls from the inlet 211 to the extrusion cover 55 on the anti-plugging shunt device 5, and then is guided by the extrusion cover 55 to the gap between the shunt ball 51 and the carbonization and activation cylinder 3, so as to fall to the screw feed bar 6 through the gap.

[0048] At the same time, when the nozzle 431 is heated, the heated gas flow can be driven to move towards the direction of the guide ring piece 41, the high-temperature gas flow enters between the two converging sections 412 under the impact of the heated gas flow of the nozzle 431, and then enters the guide section 413 through the two converging sections 412, and then enters the heat equalizing sleeve 42 through the guide pipe 411 and the guide inlet hole 421. Since the high-temperature gas flow sprayed by the guide pipe 411 is consistent with the rotation direction of the guide helical piece 423, the high-temperature gas flow will rotate and move along the rotation direction of the guide helical piece 423, and finally the high-temperature gas flow enters the area where the gas heating pipe 43 is located through the guide outlet hole 422, thereby forming a circulation, and the material in the carbonization and activation cylinder 3 is high-temperature carbonized through the heat equalizing sleeve 42.

[0049] During the carbonization process, the material on the surface of the screw feed bar 6 can be adjusted according to the actual material flow, the second sliding block 94 and the first sliding block 95 fixed on the nut seat 93 are driven to reciprocate by the lead screw 91, the first sliding block 95 drives the adjusting screw strip 7 fixed on the first sliding block 95 to displace when the first sliding block 95 displaces, the adjusting screw strip 7 drives the adjusting column 71 on the surface of the adjusting screw strip 7 to slide on the adjusting hole 61 when the adjusting screw strip 7 displaces, the speed of the material on the surface of the screw feed bar 6 can be adjusted by adjusting the length of the adjusting column 71 extending on the adjusting hole 61.

[0050] The material on the surface of the screw feed bar 6 that is carbonized well can enter the activation area through the separation hole 311 on the separation plate 31 to perform activation work, and the material after the activation work falls from the bottom end of the carbonization and activation cylinder 3 to the inlet of the screw feeder installed on the outlet 221.
