Description

Technical Field

[0001] This invention belongs to the field of carbon material preparation technology, specifically a hard carbon material preparation device. Background Technology

[0002] Activated carbon, due to its high specific surface area, abundant pore structure, good conductivity and chemical stability, is used as a conductive additive or composite electrode material in the fields of batteries and supercapacitors. It is a core component of supercapacitors and has the characteristics of ultra-large specific surface area, concentrated pores, low ash content and good conductivity.

[0003] The preparation of activated carbon involves steps such as raw material pretreatment, carbonization, activation, and post-treatment. Post-treatment includes steps such as washing, drying, crushing, and sieving. The purpose of drying activated carbon is to remove residual moisture or organic solvents from its pore structure, while avoiding pore collapse and structural damage. Through long-term observation, it has been found that existing activated carbon particle drying methods usually use hot air drying. However, existing hot air drying equipment typically has only one air source. When the number of air sources is small, the contact area with the activated carbon particles is small, resulting in problems with uneven drying and low efficiency.

[0004] Therefore, this utility model provides a hard carbon material preparation device. Utility Model Content

The activated carbon particles on the first mesh conveyor belt and the second mesh conveyor belt are dried twice through two sets of multiple air outlet pipes, so that the hot air outlet position can be dispersed in multiple places, which can improve the drying effect of activated carbon. At the same time, when the activated carbon particles on the first mesh conveyor belt fall onto the second mesh conveyor belt, the activated carbon particles will generate a tumbling effect during the falling process, thus making the drying more uniform.

[0009] Preferably, the collection component includes a collection trough; the collection trough is fixed to the bottom of the third mesh conveyor belt; a drawer is placed inside the collection trough; with the above structure, the collection trough and the drawer can collect the debris and residue generated when the activated carbon particles are conveyed on the third mesh conveyor belt, so as to reduce the waste caused by raw materials falling on the ground. At the same time, the sliding fit between the drawer and the collection trough makes it easy to remove the collected debris and residue from the bottom of the third mesh conveyor belt.

[0010] Preferably, the protective component includes a baffle; the baffle is fixed to the end of the second mesh conveyor belt; the baffle has an arc-shaped structure; through the above structure, the baffle is connected to the second mesh conveyor belt, which can reduce the situation where activated carbon particles fall outside the second mesh conveyor belt and remain inside the box and cannot be conveyed out.

[0011] Preferably, the feeding assembly includes a guide chute; the guide chute is fixed to the end of the second mesh conveyor belt; the guide chute is inclined toward the third mesh conveyor belt; with the above structure, the guide chute is connected to the second mesh conveyor belt, reducing the possibility of activated carbon particles on the second mesh conveyor belt falling out from the gap between the second and third mesh conveyor belts when they are conveyed to the third mesh conveyor belt.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 3 As shown in the embodiment of this utility model, a hard carbon material preparation device includes a housing 1; a pair of industrial hot air blowers 11 are installed on the top of the housing 1; a pair of conduits 12 are fixed to the side wall of the housing 1; multiple air outlet pipes 13 are installed on the conduits 12; a first mesh conveyor belt 14 and a second mesh conveyor belt 15 are installed inside the housing 1; the first mesh conveyor belt 14 and the second mesh conveyor belt 15 have an interlaced structure; a discharge component is provided outside the housing 1; a protective component and a feeding component are provided on the second mesh conveyor belt 15; during operation, when drying activated carbon particles with a high moisture content, the raw material is placed on one end of the first mesh conveyor belt 14 that protrudes from the housing 1, and then the first mesh conveyor belt 14 is started to transport the activated carbon into the housing 1. When the activated carbon reaches the end of the first mesh conveyor belt 14, it will fall onto the second mesh conveyor belt 15, at which point the second mesh conveyor belt 15 transports the activated carbon to the outside of the housing 1. When the activated carbon granules are conveyed on the conveyor belt 15, the industrial hot air blower 11 is activated to blow hot air into the duct 12. Then, the hot air is diverted through the duct 12 into multiple air outlet pipes 13. At this time, the air outlet pipes 13 are located on the first mesh conveyor belt 14 and the second mesh conveyor belt 15, which will dry the activated carbon granules conveyed on the first mesh conveyor belt 14 and the second mesh conveyor belt 15. The dried activated carbon granules are discharged from the second mesh conveyor belt 15 to the outside of the housing 1. Through the above structure, the housing 1, the industrial hot air blower 11, and the duct 1 are set up. 2. In conjunction with the air outlet pipe 13 and the first mesh conveyor belt 14 and the second mesh conveyor belt 15, the activated carbon particles on the first mesh conveyor belt 14 and the second mesh conveyor belt 15 are dried twice through two sets of multiple air outlet pipes 13. This allows the hot air outlet to be dispersed in multiple places, which can improve the drying effect on the activated carbon. At the same time, when the activated carbon particles on the first mesh conveyor belt 14 fall onto the second mesh conveyor belt 15, the activated carbon particles will generate a tumbling effect during the falling process, thus making the drying more uniform.

[0025] like Figure 1As shown, the discharge assembly includes a third mesh conveyor belt 2; the third mesh conveyor belt 2 is installed outside the housing 1; a pair of fixed frames 21 are fixedly connected to the top of the third mesh conveyor belt 2; a cooling fan 22 is installed on the fixed frame 21; a turning assembly is provided on the third mesh conveyor belt 2; a collection assembly is provided at the bottom of the third mesh conveyor belt 2; during operation, when activated carbon particles are discharged from the second mesh conveyor belt 15, they will fall onto the third mesh conveyor belt 2. At this time, the third mesh conveyor belt 2 is started to transport the dried activated carbon particles, and at the same time, the cooling fan 22 is started to blow air onto the surface of the third mesh conveyor belt 2. At this time, the activated carbon particles transported on the third mesh conveyor belt 2 can be cooled. Through the above structure, the third mesh conveyor belt 2, the fixed frame 21 and the cooling fan 22 are set to facilitate the cooling of the dried activated carbon particles, so as to reduce the situation where the residual temperature of the activated carbon particles is too high, which will affect subsequent processing.

[0026] like Figure 3 and Figure 4 As shown, the material turning assembly includes a reciprocating screw 3; the reciprocating screw 3 is rotatably connected to a third mesh conveyor belt 2; a motor 31 is fixedly connected to the side wall of the third mesh conveyor belt 2; the output end of the motor 31 is fixedly connected to the reciprocating screw 3; a slider 32 is installed in the middle of the reciprocating screw 3; a pair of toothed plates 33 are fixedly connected to the bottom of the slider 32; the toothed plates 33 are correspondingly arranged with the cooling fan 22; during operation, the motor 31 is started to drive the reciprocating screw 3 to rotate, at which time the slider 32 moves back and forth on the motor 31. The slider 32 drives the toothed plates 33 on both sides to reciprocate on the third mesh conveyor belt 2. The toothed plates 33 are located below the cooling fan 22. Thus, when the cooling fan 22 blows air to cool the activated carbon particles, it can turn the activated carbon particles conveyed below the cooling fan 22. Through the above structure, the reciprocating screw 3, motor 31 and slider 32 are set up and the toothed plates 33 are used in conjunction to turn the activated carbon particles below the cooling fan 22 while it is cooling the activated carbon particles, so as to improve the cooling effect of the activated carbon particles.

[0027] like Figure 3As shown, the collection assembly includes a collection trough 4; the collection trough 4 is fixed to the bottom of the third mesh conveyor belt 2; a drawer box 41 is placed inside the collection trough 4; during operation, when the dried activated carbon particles are conveyed on the third mesh conveyor belt 2, some residue may fall off. At this time, the residue falls downward through the mesh holes on the third mesh conveyor belt 2 and enters the drawer box 41 below the third mesh conveyor belt 2 for collection. After collection, the drawer box 41 is pulled out, the collected residue is removed, and then the drawer box 41 is inserted into the collection trough 4. Through the above structure, the collection trough 4 and the drawer box 41 can collect the debris and residue generated when the activated carbon particles are conveyed on the third mesh conveyor belt 2, so as to reduce the waste caused by raw materials falling on the ground. At the same time, the sliding fit between the drawer box 41 and the collection trough 4 makes it easy to remove the collected debris and residue from the bottom of the third mesh conveyor belt 2.

[0028] like Figure 2 As shown, the protective component includes a baffle 5; the baffle 5 is fixed to the end of the second mesh conveyor belt 15; the baffle 5 has an arc-shaped structure; during operation, when activated carbon particles on the first mesh conveyor belt 14 fall onto the second mesh conveyor belt 15, or when the particles fall or bounce off the outside of the second mesh conveyor belt 15, they will be blocked by the baffle 5. At this time, the baffle 5 will cause the activated carbon particles to fall back onto the second mesh conveyor belt 15. Through the above structure, by setting the baffle 5 to connect the second mesh conveyor belt 15, the situation where activated carbon particles fall off the outside of the second mesh conveyor belt 15 and remain inside the box 1 and cannot be conveyed out can be reduced.

[0029] like Figure 1 As shown, the feeding assembly includes a guide trough 6; the guide trough 6 is fixed to the end of the second mesh conveyor belt 15; the guide trough 6 is inclined towards the third mesh conveyor belt 2; during operation, when activated carbon particles on the second mesh conveyor belt 15 are conveyed to the third mesh conveyor belt 2, the activated carbon particles will pass through the guide trough 6. At this time, the guide trough 6 is inclined towards the third mesh conveyor belt 2, which allows the activated carbon particles to slide towards the third mesh conveyor belt 2. Through the above structure, the guide trough 6 is connected to the second mesh conveyor belt 15, reducing the possibility of activated carbon particles on the second mesh conveyor belt 15 falling out from the gap between the second mesh conveyor belt 15 and the third mesh conveyor belt 2 when they are conveyed to the third mesh conveyor belt 2.

[0030] like Figure 4 As shown, the toothed plate 33 is made of stainless steel. Through the above structure, the toothed plate 33 is made of stainless steel, which can improve the wear resistance and corrosion resistance of the toothed plate 33, thereby increasing the service life of the toothed plate 33.

[0031] Working principle: When drying activated carbon granules with high moisture content, the raw material is placed on the end of the first mesh conveyor belt 14 that protrudes from the box 1. Then, the first mesh conveyor belt 14 is started to transport the activated carbon into the box 1. When the activated carbon reaches the end of the first mesh conveyor belt 14, it will fall onto the second mesh conveyor belt 15. At this time, the second mesh conveyor belt 15 transports the activated carbon to the outside of the box 1. While the activated carbon is being transported on the first mesh conveyor belt 14 and the second mesh conveyor belt 15, the industrial hot air blower 11 is started to blow hot air into the duct 12, and then the hot air is distributed into multiple air outlet pipes 13 through the duct 12. At this time, the exhaust pipe 13 is located on the first mesh conveyor belt 14 and the second mesh conveyor belt 15, which will dry the activated carbon particles conveyed on the first mesh conveyor belt 14 and the second mesh conveyor belt 15. The dried activated carbon particles are discharged from the second mesh conveyor belt 15 to the outside of the box 1. When the activated carbon particles are discharged from the second mesh conveyor belt 15, they will fall onto the third mesh conveyor belt 2. At this time, the third mesh conveyor belt 2 is started to convey the dried activated carbon particles, and at the same time, the cooling fan 22 is started to blow air onto the surface of the third mesh conveyor belt 2. At this time, the activated carbon particles conveyed on the third mesh conveyor belt 2 can be cooled. Motor 31 drives reciprocating screw 3 to rotate. At this time, slider 32 moves back and forth on motor 31. Slider 32 drives toothed plates 33 on both sides to move back and forth on the third mesh conveyor belt 2. The toothed plates 33 are located below cooling fan 22. So when cooling fan 22 blows air to cool activated carbon particles, it can turn the activated carbon particles conveyed below cooling fan 22. When the dried activated carbon particles are conveyed on the third mesh conveyor belt 2, some residue will fall off. At this time, the residue falls down through the mesh of the third mesh conveyor belt 2 and enters the collection box 41 below the third mesh conveyor belt 2 for collection. Then, the collection box 41 is pulled out, the collected residue is removed, and then the collection box 41 is inserted into the collection trough 4. When the activated carbon particles on the first mesh conveyor belt 14 fall onto the second mesh conveyor belt 15, when the particles fall or bounce off the outside of the second mesh conveyor belt 15, they will be blocked by the baffle 5. At this time, the baffle 5 will cause the activated carbon particles to fall back onto the second mesh conveyor belt 15. When the activated carbon particles on the second mesh conveyor belt 15 are conveyed onto the third mesh conveyor belt 2, the activated carbon particles will pass through the guide trough 6. At this time, the guide trough 6 is tilted towards the third mesh conveyor belt 2, which allows the activated carbon particles to slide onto the third mesh conveyor belt 2.
