Description

Technical Field

[0001] This utility model relates to pretreatment equipment for porous carbon materials, and more particularly to a pretreatment equipment for porous carbon materials. Background Technology

[0002] Porous carbon materials are carbon materials with pore structures of different sizes. They have highly developed specific surface areas and pore structures, and their pore sizes can range from ultrafine nanoscale micropores at the molecular size to micron-sized pores suitable for microbial activity. Due to their excellent physicochemical properties, such as electrical conductivity, thermal conductivity, high temperature resistance, and corrosion resistance, they show excellent application prospects in catalysis, lithium battery electrode materials, adsorption, ammonia storage, capacitors and other fields. In the process of processing and using porous carbon raw materials, multi-layer sieving is required.

[0003] Chinese Patent CN217963472U discloses a multi-layer screening device for processing porous carbon raw materials. The device includes an outer box, an inner box, a first bearing, a motor, screens, a feed hopper, and a drive gear. The outer box and the inner box are rotatably connected by the first bearing. The top wall of the outer box has a first opening, and the top wall of the inner box has a second opening. The feed hopper passes through the first opening and the second opening and communicates with the inner box. The motor is installed at the bottom edge of the outer box, and the drive gear is fixedly installed on the motor shaft. The outer side wall of the inner box has a first gear tooth that meshes with the drive gear. The screens are detachably installed on the inner box and include a first screen, a second screen, a third screen, and a fourth screen. The screen holes of the first screen, the second screen, the third screen, and the fourth screen decrease in size and are installed sequentially from top to bottom. The first screen is an inverted frustum shape. The outer box has a first door, and the inner box has a second door.

[0004] However, the above-mentioned patents have the following shortcomings:

[0005] The aforementioned patent uses an inverted frustum shape for the first screen. Because the inverted frustum shape of the first screen can accommodate more porous carbon raw materials, and the contact area between the porous carbon raw materials and the first screen is larger, the first screen is less prone to clogging. However, the aforementioned patent does not have a quantitative feeding structure. When too much material accumulates on the surface of the first screen, the accumulated material will press the material at the bottom onto the screen surface due to gravity, making it difficult for the material to pass through the screen, thereby reducing the screening efficiency of the device. Utility Model Content

[0006] This utility model provides a raw material pretreatment device for porous carbon materials, aiming to solve the problem mentioned in the background art that the above-mentioned patent does not have a quantitative feeding structure. When too much material accumulates on the surface of the first screen, the accumulated material will be squeezed onto the screen surface by gravity, making it difficult for the material to pass through the screen, thereby reducing the screening efficiency of the device.

[0007] This utility model is implemented as follows: a raw material pretreatment device for porous carbon materials includes a shell, a feed pipe is provided through the top of the shell and fixedly connected to the shell, a discharge pipe is provided at the bottom of the shell, a support frame is provided below the shell, and multiple support rods are fixedly connected between the support frame and the shell. A quantitative feeding structure is provided inside the feed pipe, and the quantitative feeding structure is used to control the feeding speed in the device.

[0008] The shell is equipped with a multi-stage screening structure, which is used to screen the material inside the shell in multiple stages.

[0009] The bottom of the housing is provided with a driving structure, which drives the quantitative feeding structure and the multi-stage screening structure simultaneously.

[0010] Preferably, the quantitative feeding structure includes a baffle, which is disposed inside the feed pipe, and the outer periphery of the baffle is fixedly connected to the inner wall of the feed pipe;

[0011] The baffle has multiple rotating grooves on its surface, all of which are distributed around the center of the baffle. A mounting box is provided through the middle of the baffle and is fixedly connected to the baffle. A first rotating shaft is provided through the bottom of the mounting box and is rotatably connected to the mounting box. A rotating plate is fixedly connected to the top of the first rotating shaft.

[0012] The top of the rotating plate is fixedly connected to a drive gear ring, and the top of the drive gear ring is meshed with multiple driven gears. The side walls of the multiple driven gears are fixedly connected to second rotating shafts. The multiple second rotating shafts are respectively arranged through multiple rotating slots. The ends of the multiple second rotating shafts are respectively rotatably connected to the inner walls of the multiple rotating slots. The outer circumferences of the multiple second rotating shafts are fixedly connected to conveying rollers, and the outer circumferences of the multiple conveying rollers are provided with multiple conveying slots.

[0013] The conveying roller is matched with the rotating groove;

[0014] When the rotating plate is driven to rotate by the first rotating shaft, the rotating plate can drive the active gear ring to rotate synchronously. At the same time, the active gear ring will drive multiple driven gears to rotate synchronously. Meanwhile, the multiple driven gears will drive multiple conveying rollers to rotate in multiple rotating grooves through multiple second rotating shafts.

[0015] When material accumulates on top of the baffle, the conveying roller will drive multiple rotating grooves on its outer periphery to rotate synchronously when it rotates. The accumulated material falls into the rotating grooves due to gravity. The rotation of the rotating grooves can transport the material from the top of the baffle to the bottom of the baffle. Afterwards, the material will leave the rotating grooves due to gravity. Therefore, the reciprocating rotation of the conveying roller can continuously transport the material from the top of the baffle to the bottom of the baffle. Since the volume of multiple rotating grooves is the same, the material discharge speed in the feed pipe can be controlled by controlling the rotation speed of the conveying grooves.

[0016] Therefore, the feeding speed of the material in the feed pipe can be controlled by controlling the rotation speed of the first rotating shaft in the above manner.

[0017] Preferably, the multi-stage screening structure includes a first screening plate, a second screening plate, and a third screening plate. The outer periphery of the first screening plate is fixedly connected to the inner wall of the shell. A first rotating cylinder is rotatably connected to the middle of the first screening plate. A plurality of first stirring rods are fixedly connected to the side wall of the first rotating cylinder.

[0018] The outer periphery of the second screening plate is fixedly connected to the inner wall of the shell, and a second rotating cylinder is rotatably connected to the middle of the second screening plate. A plurality of second stirring rods are fixedly connected to the side wall of the second rotating cylinder.

[0019] The outer periphery of the third screening plate is fixedly connected to the inner wall of the shell, and a third rotating cylinder is rotatably connected to the middle of the third screening plate. Multiple third stirring rods are fixedly connected to the side wall of the third rotating cylinder.

[0020] The second screening plate is disposed at the bottom of the first screening plate, and the third screening plate is disposed at the bottom of the second screening plate. The aperture of the first screening plate is larger than the aperture of the second screening plate, and the aperture of the second screening plate is larger than the aperture of the first screening plate.

[0021] After the material enters the shell, it first falls onto the surface of the first screening plate. At this time, the first rotating cylinder drives multiple first stirring rods to rotate. The material on the surface of the first screening plate can be stirred by the multiple first stirring rods, thereby preventing the material from accumulating on the surface of the first screening plate. The stirring of the material can also speed up the speed at which the material passes through the first screening plate.

[0022] The material passing through the first screening plate will fall onto the surface of the second screening plate. At this time, the second rotating cylinder drives multiple second stirring rods to rotate. The material on the surface of the second screening plate can be stirred by the multiple second stirring rods, thereby preventing the material from accumulating on the surface of the second screening plate. The stirring of the material can also speed up the speed at which the material passes through the second screening plate.

[0023] The material passing through the second screening plate will fall onto the surface of the third screening plate. At this time, the third rotating cylinder drives multiple third stirring rods to rotate. The material on the surface of the third screening plate can be stirred by the multiple third stirring rods, thereby preventing the material from accumulating on the surface of the third screening plate. The stirring of the material can also speed up the speed at which the material passes through the third screening plate.

[0024] The material that has been screened by the first, second and third screening plates will fall to the bottom of the shell and be discharged through the discharge pipe at the bottom of the shell.

[0025] Preferably, the drive structure includes a stepper motor, the top of which is fixedly connected to the housing, and a rotating rod is fixedly connected to the output shaft of the stepper motor;

[0026] The rotating rod is arranged to pass through the third rotating cylinder, the second rotating cylinder and the first rotating cylinder in sequence. The first rotating cylinder, the second rotating cylinder and the third rotating cylinder are all fixedly connected to the rotating rod. The top end of the rotating rod is fixedly connected to the first rotating shaft.

[0027] A stepper motor can drive the rotating rod to rotate, and the rotating rod will simultaneously drive the fourth rotating cylinder, the third rotating cylinder, the second rotating cylinder, the first rotating cylinder and the first rotating shaft to rotate.

[0028] Preferably, a first guide block is fixedly connected to the top of the baffle, the top of the first guide block is arc-shaped, and the number of the first guide blocks is multiple; a second guide block is fixedly connected to the top of the mounting box, and the second guide block is conical.

[0029] By setting a first guide block and a second guide block, the material entering the feed pipe can be guided to the conveying groove on the outer periphery of multiple conveying rollers, thereby avoiding the accumulation of material on the baffle surface.

[0030] Preferably, the bottom inner side of the housing is provided with a sweeping structure, the sweeping structure includes a fourth rotating cylinder, the fourth rotating cylinder is fixedly sleeved on the outer periphery of the rotating rod, and a plurality of sweeping rods are fixedly connected to the side wall of the fourth rotating cylinder, the sweeping rods being matched with the discharge pipe;

[0031] When the fourth rotating drum rotates, it can drive multiple sweeping rods to rotate. The rotating sweeping rods can sweep the material located on the bottom wall inside the shell, and then discharge the material when it is swept to the discharge pipe, thereby speeding up the discharge speed of the device.

[0032] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a raw material pretreatment device for porous carbon materials.

[0033] 1. By setting a quantitative feeding structure, the feeding speed in the device can be controlled, thereby avoiding the accumulation of material in the multi-stage screening structure and the blockage of the multi-stage screening structure due to the feeding speed being greater than the material screening speed.

[0034] 2. By setting up a multi-stage screening structure, materials can be screened in multiple stages, and the screening accuracy of the device can be improved. The first stirring rod, the second stirring rod, and the third stirring rod in the multi-stage screening structure can respectively stir the materials on the surface of the first screening plate, the second screening plate, and the third screening plate, thereby avoiding the accumulation of materials at a certain point on the screening plate, thus improving the screening efficiency of the screening plate and thus improving the screening efficiency of the device. Furthermore, the driving structure can simultaneously drive the multi-stage screening structure and the quantitative feeding structure. Attached Figure Description

[0063] The second screening plate 32 is disposed at the bottom of the first screening plate 31, and the third screening plate 33 is disposed at the bottom of the second screening plate 32.

[0068] Working principle and usage process of this utility model:

[0069] The stepper motor 41 can drive the rotating rod 42 to rotate, and the rotating rod 42 simultaneously drives the first rotating shaft 24 to rotate. When the first rotating shaft 24 drives the rotating plate 25 to rotate, the rotating plate 25 can drive the driving gear ring 26 to rotate synchronously. At the same time, the driving gear ring 26 will drive multiple driven gears 27 to rotate synchronously. Meanwhile, the multiple driven gears 27 will drive multiple conveying rollers 29 to rotate in multiple rotating grooves 22 through multiple second rotating shafts 28 respectively.

[0070] When material accumulates on the top of the baffle 21, the conveying roller 29 will drive the multiple rotating grooves 22 on its outer periphery to rotate synchronously when it rotates. The accumulated material falls into the rotating grooves 22 due to gravity. The rotation of the rotating grooves 22 can transport the material from the top of the baffle 21 to the bottom of the baffle 21. Afterwards, the material will leave the rotating grooves 22 due to gravity. Therefore, the reciprocating rotation of the conveying roller 29 can continuously transport the material from the top of the baffle 21 to the bottom of the baffle 21. Since the multiple rotating grooves 22 have the same volume, the material feeding speed in the feed pipe 11 can be controlled by controlling the rotation speed of the conveying groove 210.

[0071] The stepper motor 41 can drive the rotating rod 42 to rotate. While the rotating rod 42 is rotating, it will simultaneously drive the fourth rotating cylinder 51, the third rotating cylinder 38, the second rotating cylinder 36 and the first rotating cylinder 34 to rotate. After the material enters the shell 1, the material will first fall onto the surface of the first screening plate 31. At this time, the first rotating cylinder 34 drives multiple first stirring rods 35 to rotate. The material on the surface of the first screening plate 31 can be stirred by the multiple first stirring rods 35, thereby avoiding the accumulation of material on the surface of the first screening plate 31. The stirring of the material can also speed up the speed at which the material passes through the first screening plate 31.

[0072] The material passing through the first screening plate 31 will fall onto the surface of the second screening plate 32. At this time, the second rotating cylinder 36 drives multiple second stirring rods 37 to rotate. The material on the surface of the second screening plate 32 can be stirred by the multiple second stirring rods 37, thereby preventing the material from accumulating on the surface of the second screening plate 32. The stirring of the material can speed up the speed at which the material passes through the second screening plate 32.

[0073] The material passing through the second screening plate 32 will fall onto the surface of the third screening plate 33. At this time, the third rotating cylinder 38 drives multiple third stirring rods 39 to rotate. The material on the surface of the third screening plate 33 can be stirred by the multiple third stirring rods 39, thereby preventing the material from accumulating on the surface of the third screening plate 33. The stirring of the material can speed up the speed at which the material passes through the third screening plate 33.

[0074] When the fourth rotating drum 51 rotates, it can drive multiple sweeping rods 52 to rotate. The rotating sweeping rods 52 can sweep the material located on the bottom wall inside the housing 1, so that the material is discharged when it is swept to the discharge pipe 12, thereby speeding up the discharge speed of the device.
