Description

Technical Field

[0002] Supercapacitors are between batteries and ordinary capacitors. They have the characteristics of fast charging and discharging with large currents of capacitors, as well as the energy storage characteristics of batteries, and have a long repeated service life. Supercapacitors achieve the conversion of electric energy-electric field energy-electric energy during the "charging-discharging" process. The whole process does not have any chemical reaction and does not pollute the surrounding environment. It is an ideal energy storage device. In recent years, high-specific surface area and high-purity activated carbon have attracted much attention as electrode materials for supercapacitors. Activated carbon uses its porous characteristics to complete energy storage, but due to the limitation of pore size, the rate of electrolyte diffusion and migration is not high, which will limit the power density of supercapacitors.

[0003] At present, the production line of activated carbon battery materials mainly includes crushers, agitators and activation furnaces, among which the activation furnace equipment is particularly important. The raw materials need to be preheated in the activation furnace, and then the temperature is gradually increased to activate the preheated materials in the furnace, so as to obtain activated carbon with controllable specific surface area and pore size distribution and excellent performance. However, the following problems were found in actual production. In the traditional production line, the raw materials are of different sizes after being crushed by the crusher, and the use effects of the prepared activated carbon are different.

DETAILED DESCRIPTION

[0031] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0032] like Figure 1-6 As shown, a production line of super battery materials includes a crusher, a mixer and an activation furnace connected in sequence. The crusher and the mixer can be conventionally sold on the market, and no further details are given here. The activation furnace includes a furnace body 1, an upper material receiving frame 21, a lower material receiving frame 22 and a driving mechanism. A heating box 11 is provided in the furnace body 1, and a heating chamber is provided inside the heating chamber. The upper material receiving frame 21 and the lower material receiving frame 22 are arranged to be tilted downward from the back to the front, and most of the areas of the upper material receiving frame 21 and the lower material receiving frame 22 pass through the heating chamber, so that the heating box 11 can fully electrically heat the materials on the upper material receiving frame 21 and the lower material receiving frame 22. The two ends of the upper material receiving frame 21 and the lower material receiving frame 22 are connected to the driving mechanism, and the driving mechanism drives the upper material receiving frame 21 and the lower material receiving frame 22 to repeatedly translate horizontally. The upper material receiving frame 21 is provided with a filter hole 211, which can facilitate the rapid dispersion of the materials on the upper material receiving frame 21 during the repeated translation process. A feed pipe 12 is provided above the higher end of the upper material support frame 21 of the furnace main body 1, and the feed pipe 12 can be used to input a first discharge pipe 13 below the lower end of the upper material support frame 21 of the furnace main body 1, and a second discharge pipe 14 is provided below the lower end of the lower material support frame 22 of the furnace main body 1. The lower ends of the first discharge pipe 13 and the second discharge pipe 14 can be connected to the recovery box respectively. When the activation furnace is activated, the activated carbon on the upper material support frame 21 falls into the first discharge pipe 13 for collection, and the activated carbon on the lower material support frame 22 falls into the second discharge pipe 14 for collection.

[0033] In this embodiment, the driving mechanism includes a motor 31, a swing rod 32, a guide frame 33, a guide block 34, a guide rod 35, a guide rail 36 and a driving frame 4. The motor 31 is fixedly mounted on the upper end of the furnace body 1. The output shaft of the motor 31 is connected to one end of the swing rod 32. The other end of the swing rod 32 is rotatably connected to the guide block 34 through a rotating shaft. The guide rod 35 is horizontally connected to both sides of the guide frame 33. The guide rod 35 is connected to the upper end of the driving frame 4. The guide frame 33 is provided with an arc guide groove 331. The guide block 34 is embedded in the arc guide groove 331 for sliding connection. The guide rail 36 is fixed to the upper end of the furnace body 1. The guide rod 35 is slidably connected to the guide rail 36. The guide rail 36 can guide and support the guide rod 35, so that the guide rod 35 can translate more smoothly. The lower end of the guide frame 33 is movably connected to the upper material support frame 21 and the lower material support frame 22. The driving frame 4 includes a main frame body 41, a guide column 42, a first slide bar 43, a second slide bar 44, an adapter frame 45 and an adapter plate 46. The guide column 42 is fixedly connected to the left and right sides of the main frame body 41. The left and right sides of the upper material support frame 21 and the lower material support frame 22 are provided with fixed plates 23. The fixed plates 23 are slidably connected to the guide column 42. A limiting boss 421 is provided on the guide column 42, and a first spring 422 is sleeved on the guide column 42. The two ends of the first spring 422 are respectively against the fixed plate 23 and the limiting boss 421, so that the upper material support frame 21 and the lower material support frame 22 can be movably connected to the main frame body 41. The first slide bar 43 is horizontally arranged and slidably connected to the furnace body 1. The two ends of the first slide bar 43 are respectively connected to the main frame 41 and the adapter frame 45. The upper end of the furnace body 1 is provided with a guide sleeve 15. The second slide bar 44 is slidably connected to the guide sleeve 15. The guide sleeve 15 can support the second slide bar 44, so that the connection of the guide frame 33 is more secure. The two ends of the second slide bar 44 are respectively connected to the adapter frame 45 and the adapter plate 46, and the guide bar is connected to the adapter plate 46. After adopting the above structure, the motor 31 drives the swing bar 32 to rotate. During the rotation process, the swing bar 32 will drive the guide block 34 to repeatedly slide up and down in the guide frame 33 along the extension direction of the arc guide groove 331, thereby driving the guide frame 33 to repeatedly translate back and forth, and then transmit through the guide rod 35 to drive the driving frame 4 at the front and rear ends to translate synchronously.

[0034] In order to spread the materials more quickly and evenly on the upper material support frame 21 and the lower material support frame 22, both sides of the upper material support frame 21 and the lower material support frame 22 are provided with a top plate 24 extending in the horizontal direction, and the upper surface of the top plate 24 is provided with a first convex particle 241, and the interior of the heating box 11 is provided with an activation cavity, and the side wall of the activation cavity is provided with an upper limit plate 111 and a lower limit plate 112, and the top plate 24 is arranged between the upper limit plate 111 and the lower limit plate 112. A slide groove 113 is provided in the limit plate 111, and a sliding block 114 is slidably connected therein. A second protrusion 115 is provided on the lower surface of the sliding block 114, and the second protrusion 115 is located between the two first protrusions 241. A plurality of accommodating grooves are opened on the upper surface of the sliding block 114, and a second spring 116 is provided in the accommodating groove. The upper end of the second spring 116 abuts against the upper groove wall of the slide groove 113, and the lower end of the second spring 116 abuts against the bottom wall of the accommodating groove. After adopting the above structure, when the driving mechanism drives the upper material support frame 21 and the lower material support frame 22 to translate, the slider 114 can keep the second convex particle 115 and the first convex particle 241 on the top plate 24 in effective contact at all times under the elastic force of the second spring 116. Since the upper material support frame 21 and the lower material support frame 22 are movably connected to the guide frame 33 through the first spring 422, the upper material support frame 21 and the lower material support frame 22 will vibrate repeatedly during translation, so that the materials can be spread out quickly, and the sorting effect of the filter hole 211 can also be enhanced, and the sorting efficiency can be accelerated. And when the materials on the upper material support frame 21 and the lower material support frame 22 gradually increase, the upper material support frame 21 and the lower material support frame 22 will sink, and at this time, the second spring 116 can push against the slider 114 so that the slider 114 can maintain contact with the top plate 24, thereby ensuring that the upper material support frame 21 and the lower material support frame 22 maintain a vibrating state during translation.

[0035] In this embodiment, the front end of the furnace body 1 is provided with an air inlet pipe 16, the rear end of the furnace body 1 is provided with an exhaust pipe 17, and a diverter air box 18 is provided inside the furnace body 1. The air inlet pipe 16 is communicated with the inside of the diverter air box 18, and a plurality of air outlets 181 are provided on the side wall of the diverter air box 18. The diverter air box 18 is provided with an upper outlet flow channel 182 arranged toward the upper material support frame 21 on the side of the upper outlet 181, and the diverter air box 18 is provided with a lower outlet flow channel 183 arranged toward the lower material support frame 22 on the side of the lower outlet 181. The front end of the lower material support frame 22 is fixedly connected with a horizontal plate 51, and a slidably connected baffle plate 52 is provided on the horizontal plate 51. The baffle plate 52 is extended in the vertical direction, and the upper end of the baffle plate 52 extends into the diverter air box 18 and is slidably connected with the diverter air box 18. The baffle plate 52 is provided with a plurality of air guide ports 53. After adopting the above structure, during pretreatment and activation treatment, nitrogen and activated gas can be introduced into the split air box 18 through the air inlet pipe 16, and the gas is transported to the upper material support frame 21 through the gas outlet 181 and the upper outlet flow channel 182. The gas passes through the air guide port 53 and the gas outlet 181 and then is transported to the lower material support frame 22 through the lower outlet flow channel 183. The gas is transported along the extension direction of the upper material support frame 21 and the lower material support frame 22. Since larger materials require more activated gas to react, the gas outlet volume of the upper outlet flow channel 182 can be set larger so that the materials on the upper material support frame 21 can quickly and fully contact with the activated gas. Since the amount of material on the material rack is too small, the initial gas outlet volume of the lower outlet air duct 183 can be set to be smaller. When the material on the lower material rack 22 gradually increases, the upper material rack 21 will sink. When the upper material rack 21 sinks, it will drive the horizontal plate 51 to sink together, thereby pulling the baffle 52 downward, reducing the blocking area of ​​the baffle 52 on the air outlet 181, increasing the gas flow rate, and allowing the material on the lower material rack 22 to fully react.

[0036] As another embodiment of the present invention, Figure 2 and attached Figure 4 As shown, a heat insulation board can be provided at the front and rear ends of the heating box 11, and the heat insulation board has a through hole for the upper material support frame 21 and the lower material support frame 22 to pass through. The height of the draw-out hole is slightly greater than the height of the upper material support frame 21 and the lower material support frame 22 to avoid interference between the upper material support frame 21 and the lower material support frame 22 during translation, and the upper outlet air channel 182 and the lower outlet air channel 183 can extend to the through hole, so that more activated gas can enter the interior of the heating box 11 faster. In addition, there is an outlet pipe connected to the exhaust pipe on the heat insulation board so that the generated exhaust gas can be discharged from the furnace body together. In this way, the heat insulation effect of the heating box 11 can be better and the activation efficiency can be further improved.

[0037] A preparation method based on the above production line comprises the following steps:

[0038] (1) The raw materials are dried and transported to a crusher for crushing and screening. The number of screens used for screening is 30-50 meshes;

[0039] (2) introducing the crushed material into a mixer and adding an activator for stirring and mixing;

[0040] (3) The stirred material is continuously conveyed from the feed pipe 12 to the upper material support frame 21. When feeding, the motor 31 is started to drive the upper material support frame 21 to repeatedly translate back and forth, so that the upper material support frame 21 repeatedly translates and vibrates, and the material is quickly spread out, and some smaller materials are filtered through the filter holes 211 and fall onto the lower material support frame 22, thereby realizing small separation of the materials;

[0041] (4) nitrogen is transported into the furnace body 1 through the air inlet pipe 16, and the heating box 11 is heated to 300-450° C. to pre-treat the material. The pre-treatment time is 2-3 hours;

[0042] (5) The activated gas is transported into the furnace body 1 through the air inlet pipe 16, and the heating box 11 increases the heating temperature to 650-800° C. to activate the material for 1-2 hours to obtain activated activated carbon;

[0043] (6) Then, the motor 31 is started to drive the upper material support frame 21 and the lower material support frame 22 to translate and vibrate, and the prepared activated carbon is transported to the first discharge pipe 13 and the second discharge pipe 14 respectively, and then the activated carbon is collected in a recovery box.

[0044] Preferably, the activation gas is a mixed gas of water vapor and carbon dioxide, and the activator is sodium hydroxide. The raw material is cottonseed hull.

[0045] Compared with the prior art, the beneficial effect is that the present invention achieves the effect of sorting materials by providing an upper material support frame 21 and a lower material support frame 22 inside the activation furnace, and providing a filter hole 211 at the feeding end of the upper material support frame 21, so that the material size can be automatically sorted when the material is activated in the activation furnace, thereby improving production efficiency. In addition, the upper material support frame 21 and the lower material support frame 22 are repeatedly translated and vibrated by a driving mechanism, and during this process, the material can be more quickly and evenly dispersed on the upper material support frame 21 and the small material support frame, so that the material can be more fully activated with the activation gas, thereby improving the activation quality and activation efficiency of the activation furnace, and further improving the preparation efficiency of the production line of the present invention.
