Description

Technical Field

[0001] The invention relates to the technical field of activated carbon manufacturing, in particular to a modified activated carbon manufacturing device based on coconut shell raw materials. Background Art

[0002] In order to increase the specific surface area, pore structure and surface chemical properties of activated carbon, thereby enhancing the adsorption capacity of specific substances (such as organic matter, heavy metal ions, gases, etc.), a modification process is required in the preparation of activated carbon using coconut shell as raw material. However, in the process of modifying and impregnating coconut shell activated carbon with metal salt solution, a serious problem is faced.

[0003] Normally, when metal salt solutions are used for impregnation, the metal salt particles are prone to precipitation, which will greatly affect the adsorption effect of activated carbon on metal ions. Specifically, the metal ions adsorbed by the activated carbon are unevenly distributed, which not only greatly reduces the modification effect of the activated carbon, but also seriously affects the quality and performance of the activated carbon. This uneven adsorption will cause the activated carbon to perform unstable in practical applications. For example, when used for wastewater treatment, it may not be able to effectively remove specific pollutants; in terms of gas adsorption, it is also difficult to achieve the expected purification effect. In addition, due to uneven adsorption, the pore structure of the activated carbon may be partially blocked, thereby reducing its specific surface area and porosity, further weakening its adsorption capacity. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a modified activated carbon manufacturing equipment based on coconut shell raw materials, which solves the problem that the quality and performance of activated carbon are negatively affected due to the uneven distribution of metal ions adsorbed by the activated carbon.

[0014] Preferably, the driving mechanism includes a limit seat, which is arranged on the outer wall of the modification bin, a servo motor 1 is fixedly connected to one side of the outer wall of the limit seat, a driving wheel is fixedly connected to the output end of the servo motor 1, a driving frame is fixedly connected to the outer wall of the modification bin, the driving frame is slidably connected to the inside of the limit seat, and the driving wheel is meshingly connected to the driving frame.

[0015] Preferably, the reversal assembly includes a swivel, which is symmetrically arranged on the inner wall of the reforming bin, the inner wall of the swivel is fixedly connected with a telescopic plate, the other end of the long axis passes through two groups of telescopic plates in sequence and is fixedly connected with a T-shaped seat 2, the outer wall of the telescopic plate on one side is fixedly connected with a reversal frame, one side of the outer wall of the connecting bin is fixedly connected with a reversal motor, the output end of the reversal motor is fixedly connected with a reversal wheel, and the reversal wheel is meshingly connected with the reversal frame.

[0016] Preferably, the outer wall of the serpentine net is fixedly connected with short shafts, and adjacent short shafts are connected by telescopic rods.

[0017] Preferably, an anti-collision net is fixedly connected to one side of the inner wall of the reforming bin, and a frame hole and a through hole are respectively opened on the outer wall of the anti-collision net, and the long axis passes through the frame hole.

[0018] Preferably, another set of limit seats is provided on one side of the outer wall of the reforming bin, an auxiliary ring is fixedly connected to one side of the outer wall of the reforming bin, and the auxiliary ring is slidably connected to the inside of the limit seat.

[0019] Preferably, a spring is provided on the outer wall of the connecting rod, and the T-shaped seat is connected to one side of the inner wall of the limiting groove through the spring.

[0020] Preferably, the inner diameter of the feed bin is smaller than the minimum inner diameter of the mesh cage.

[0021] Working principle: coconut shell activated carbon is input from the feed bin, transmitted through the connecting bin into the modification bin, and the metal salt ion solution for modified activated carbon also flows from the feed bin into the modification bin. The driving mechanism can drive the modification bin to rotate. At this time, the mesh cage remains stationary. During the rotation of the modification bin, the liquid is repeatedly lifted by the drain plate. When the drain plate moves to the vertical position at the top of the mesh cage, the liquid flows into the mesh cage due to gravity and impregnates the activated carbon in the mesh cage. During the impregnation process, the modified metal salt ion solution is in an oscillating state to avoid the precipitation of metal salt ions and uneven adsorption of activated carbon. In addition, the size and volume of activated carbon in the production process change with demand. Activated carbon with smaller volume and number is more dispersed in the mesh cage, resulting in a longer time for the modified metal salt ion solution to be adsorbed by the activated carbon. At this time, the drive motor is turned on to drive the rotating frame to rotate. The T-shaped seat slides along the limit groove under the extrusion of the rotating frame, and the area surrounded by multiple long axes changes, thereby changing the dispersion state of the activated carbon in the mesh cage and improving the modification and impregnation efficiency of the activated carbon. When the servo motor is started, it drives the driving wheel to rotate, and the driving wheel engages with the driving frame to transmit, so that the modified bin rotates. The internal drainage plate drives the modified metal salt ion liquid to continuously vibrate and pour into the mesh cage, so that the coconut shell activated carbon in the mesh cage is impregnated and adsorbed by the metal salt ion solution, thereby increasing its specific surface area and improving its porosity. The front and rear limit seats provide support for the front and rear parts of the modified bin respectively. When the T-shaped seat 1 slides in the limiting groove, it drives the volume surrounded by multiple long axes to change. When the T-shaped seat 1 rotates in the direction away from the limiting groove, the surrounded volume increases. The telescopic plate is divided into a fixed part and a sliding part. The sliding part slides with the movement of the long axis, and the fixed part completes the isolation of the mesh cage, activated carbon and drainage board while accommodating the sliding part, so as to prevent the activated carbon from falling into the drainage board. In addition, since the long axis passes through the two sets of telescopic plates in sequence, and the two ends of the long axis are respectively engaged with the telescopic plates through the T-shaped seat 1 and the T-shaped seat 2, the rotation of the telescopic plates in sequence is started through the reversing mechanism, which can drive the mesh cage to rotate as a whole, so that the internal activated carbon rotates while being impregnated with the modified metal salt ion solution, ensuring that the activated carbon adsorbs the modified solution evenly in all directions, and ensuring that the modified coconut shell activated carbon performs stably in practical applications.

[0022] The present invention provides a modified activated carbon manufacturing device based on coconut shell raw materials. It has the following beneficial effects:

[0023] 1. The present invention causes the solution to vibrate by rotating the reforming bin to avoid precipitation of metal salt ions and ensure uniform adsorption of activated carbon. At the same time, the driving motor drives the rotating frame to change the dispersion state of the activated carbon in the mesh cage, further improving the impregnation efficiency. It can process activated carbons of different sizes and volumes, especially for relatively dispersed small-volume activated carbon, effectively solving the problem of long impregnation time.

[0024] 2. The present invention drives the mesh cage to rotate as a whole through the reversing mechanism, allowing the activated carbon to rotate itself during the impregnation process, ensuring uniform adsorption of the modified solution in all directions, improving the consistency and stability of the modified effect, and increasing the specific surface area and porosity of the modified coconut shell activated carbon, thereby performing more stably in practical applications and improving the quality and performance of the product.

[0036] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a modified activated carbon manufacturing device based on coconut shell raw materials, comprising:

[0037] The reforming chamber 1, as the basic component of the whole device, is used to carry and assemble the reforming mechanism and its subordinate structural parts;

[0038] A feed bin 2, which is connected to one side of the outer wall of the reforming bin 1, and is used to input coconut shell activated carbon and reforming liquid;

[0039] A connecting bin 3, which is connected to one side of the inner wall of the feed bin 2 and is used to seal the reforming bin 1 and the feed bin 2;

[0043] The discharge bin 4 is connected to the other side of the outer wall of the reforming bin 1 and is used for transmitting the reformed activated carbon.

[0044] The reforming mechanism comprises a driving motor 5, which is fixedly connected to one side of the outer wall of the reforming bin 1, the output end of the driving motor 5 passes through the reforming bin 1 and is fixedly connected to a rotating frame 6, one side of the inner wall of the reforming bin 1 is fixedly connected to a limiting frame 7, a limiting groove 8 is provided inside the limiting frame 7, a connecting rod 9 is fixedly connected to the inner wall of the limiting groove 8, a T-shaped seat 10 is slidably connected to the outer wall of the connecting rod 9, one end of a long axis 11 is fixedly connected to one side of the outer wall of the T-shaped seat 10, the long axis 11 passes through the limiting groove 8 and the rotating frame 6 in sequence, a serpentine net 12 is fixedly connected to one side of the outer wall of the long axis 11, a plurality of serpentine nets 12 constitute a mesh cage, and a plurality of drainage plates 13 are fixedly connected to the inner wall of the reforming bin 1 at equal intervals;

[0045] The outer wall of the serpentine net 12 is fixedly connected with short shafts 24 , and adjacent short shafts 24 are connected by telescopic rods 25 .

[0046] The outer wall of the connecting rod 9 is provided with a spring 30, and the T-shaped seat 10 is connected to one side of the inner wall of the limiting groove 8 through the spring 30;

[0047] Specifically, coconut shell activated carbon is input from the feed bin 2, transmitted through the connecting bin 3 and entered into the modification bin 1, and the metal salt ion solution for modified activated carbon also flows from the feed bin 2 and enters into the modification bin 1. The driving mechanism can drive the modification bin 1 to rotate, and the mesh cage remains stationary at this time. During the rotation of the modification bin 1, the liquid is repeatedly lifted by the drainage board 13. When the drainage board 13 moves to the vertical position at the top of the mesh cage, the liquid flows into the mesh cage due to gravity and impregnates the activated carbon in the mesh cage. During the impregnation process, the modified metal salt ion solution is in an oscillating state to avoid the precipitation of metal salt ions and uneven adsorption of activated carbon. In addition, the size and volume of the activated carbon production process change with demand, and the volume and number Activated carbon with smaller mesh size is more dispersed in the mesh cage, resulting in that the modified metal salt ion solution takes a longer time to be adsorbed by the activated carbon. At this time, the driving motor 5 is turned on to drive the rotating frame 6 to rotate, and the T-shaped seat 10 slides along the limiting groove 8 under the extrusion of the rotating frame 6, and the area enclosed by the multiple long axes 11 changes, thereby changing the dispersion state of the activated carbon in the mesh cage, so that the modified impregnation efficiency of the activated carbon is improved, and the T-shaped seat 10 squeezes the spring 30 during the sliding process, and the spring 30 shrinks due to the squeezing force and generates a force to restore its original state. Therefore, when the driving motor 5 rotates in the opposite direction to change the volume enclosed by the long axis 11, the restoring force of the spring 30 can directly drive the T-shaped seat 10 to slide, thereby changing the volume of the mesh cage.

[0048] The driving mechanism includes a limit seat 14, which is arranged on the outer wall of the reforming bin 1, a servo motor 15 is fixedly connected to one side of the outer wall of the limit seat 14, a driving wheel 16 is fixedly connected to the output end of the servo motor 15, a driving frame 17 is fixedly connected to the outer wall of the reforming bin 1, the driving frame 17 is slidably connected to the inside of the limit seat 14, and the driving wheel 16 is meshedly connected to the driving frame 17;

[0049] Another set of limit seats 14 is provided on one side of the outer wall of the reforming bin 1, and an auxiliary ring 29 is fixedly connected to one side of the outer wall of the reforming bin 1, and the auxiliary ring 29 is slidably connected to the inside of the limit seat 14;

[0050] Specifically, the servo motor 15 is started to drive the driving wheel 16 to rotate, and the driving wheel 16 is meshed with the driving frame 17 to rotate the modified bin 1, and the internal drainage plate 13 drives the modified metal salt ion liquid to continuously vibrate and pour into the mesh cage, so that the coconut shell activated carbon in the mesh cage is impregnated and adsorbed by the metal salt ion solution, thereby increasing its specific surface area and improving its porosity. The front and rear limit seats 14 provide support for the front and rear parts of the modified bin 1 respectively.

[0051] The reversing assembly includes a swivel 18, which is symmetrically arranged on the inner wall of the reforming bin 1, and the inner wall of the swivel 18 is fixedly connected with a telescopic plate 19, and the other end of the long axis 11 sequentially passes through two sets of telescopic plates 19 and is fixedly connected with a T-shaped seat 20, and the outer wall of the telescopic plate 19 on one side is fixedly connected with a reversing frame 21, and one side of the outer wall of the connecting bin 3 is fixedly connected with a reversing motor 22, and the output end of the reversing motor 22 is fixedly connected with a reversing wheel 23, and the reversing wheel 23 is meshed and connected with the reversing frame 21;

[0052] An anti-collision net 26 is fixedly connected to one side of the inner wall of the reforming bin 1, and a frame hole 27 and a through hole 28 are respectively opened on the outer wall of the anti-collision net 26, and the long axis 11 passes through the frame hole 27;

[0053] Specifically, when the T-shaped seat 10 slides in the limiting groove 8, the volume enclosed by the multiple long axes 11 changes. When the T-shaped seat 10 rotates in the direction away from the limiting groove 8, the enclosed volume increases. The telescopic plate 19 is divided into a fixed part and a sliding part. The sliding part slides following the movement of the long axis 11, and the fixed part completes the isolation of the mesh cage, activated carbon and the drainage board 13 while accommodating the sliding part, thereby preventing the activated carbon from falling into the drainage board 13. In addition, since the long axis 11 passes through the two groups of telescopic plates 19 in sequence, and the two ends of the long axis 11 are respectively engaged with the telescopic plates 19 through the T-shaped seat 10 and the T-shaped seat 20, the rotation of the telescopic plates 19 in sequence is started by the reversing mechanism, which can drive the mesh cage to rotate as a whole, so that the internal activated carbon rotates while being impregnated with the modified metal salt ion solution, ensuring that the activated carbon adsorbs the modified solution uniformly in all directions, and ensuring that the modified coconut shell activated carbon performs stably in practical applications.

[0054] The inner diameter of the feed bin 2 is smaller than the minimum inner diameter of the mesh cage;

[0055] Specifically, the inside of the feed bin 2 is mainly used to transport the activated carbon. The volume of the mesh cage can be changed according to the movement of the long axis 11. The inner diameter of the feed bin 2 is smaller than the minimum inner diameter of the mesh cage, which can ensure that the activated carbon enters the feed bin 2 to complete the impregnation and adsorption.
