Description

Technical Field

[0001] The present application relates to the technical field of activated carbon production, and in particular to an activated carbon preparation system. Background Art

[0002] The characteristic parameters of activated carbon include: ash content, strength, iodine value, bulk density, etc., among which ash content refers to the content of silicon dioxide, calcium magnesium oxide, titanium dioxide, aluminum oxide, iron oxide, etc. in the activated carbon. Strength is an indicator to measure the wear resistance of activated carbon. Iodine value is a parameter that directly reflects the adsorption capacity of activated carbon. The higher the iodine value, the stronger the adsorption performance of the activated carbon. Bulk density refers to the density of activated carbon or the mass per unit volume, which affects the usage and cost of activated carbon. The above parameters of activated carbon obtained from general production are all within a range. According to the factory requirements, activated carbon within the target range needs to be mixed. When mixing, the existing mixing equipment has small gaps between some materials with finer particle sizes. Materials with relatively large particles generally sink under the small particle group or float on the small particle group, resulting in uneven mixing and failure to meet factory conditions.

[0003] To address this issue, the existing patent CN220478659U proposes a structure that, by eccentrically rotating the mixing tank and moving it up and down at the same time, controls the particles in the mixing tank so that they cannot form a regular shaking trajectory and all the particles collide and fuse. However, the eccentric rotation in this technology requires a large output power of the motor, and when the vertical up and down sliding speed is too high, the braking mechanism has high requirements, and long-term use also causes great wear on the mechanism, that is, it is not practical enough.

[0022] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0023] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity from another, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that an article or terminal device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such article or terminal device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the article or terminal device comprising the element.

[0024] like Figure 1 and Figure 3 As shown, the utility model provides an activated carbon preparation system, a feeding mechanism, and a mixing bin 1, wherein the feeding mechanism is connected to the feeding port of the mixing bin 1, the top of the mixing bin 1 includes a driving device, the interior of the mixing bin 1 includes an agitator and a protrusion, the protrusion is protruded relative to the inner wall of the mixing bin 1, the agitator includes a rotating shaft, a first spiral ribbon 11, and a second spiral ribbon, the first spiral ribbon 11 and the second spiral ribbon are both connected to the rotating shaft, the rotating shaft is connected to the driving device, the rotation radius of the first spiral ribbon 11 is smaller than the rotation radius of the second spiral ribbon, and the spiral directions of the first spiral ribbon 11 and the second spiral ribbon are opposite.

[0025] Among them, the outer wall of the mixing bin 1 is provided with a slide rail, and the slide rail is adapted to the track arranged in the circumferential direction of the mixing bin 1, and the track includes a first annular track 2 and a second annular track 3 arranged in a vertical plane, and the first annular track 2 and the second annular track 3 are installed according to a preset angle α, and the track is fixed to the bin body support 4; the feeding mechanism includes: a mixing conveyor belt 6, and multiple feeding belts 5, one end of the feeding belt 5 is provided with a combing plate, and the multiple feeding belts 5 are evenly arranged above both sides of the feeding direction of the mixing conveyor belt 6, and the discharge ends of the multiple combing plates are connected to the mixing conveyor belt 6.

[0026] The agitator for stirring the mixed materials is arranged in the mixing bin 1, comprising a first spiral belt 11 and a second spiral belt with different rotation radii, and the rotation directions of the first spiral belt 11 and the second spiral belt are opposite, so that when the agitator starts to rotate, the mixed materials in the middle area and the outer area of ​​the bin are constantly changing, and at the same time, the protrusions on the inner wall of the agitator squeeze the mixed materials, so that the carbon particles and carbon powder are evenly broken up, further increasing the collision between different carbon particles in the bin; in addition, the entire mixing bin 1 is arranged on two staggered annular tracks, and the mixing bin 1 is driven to move along different annular tracks, so that the mixing bin 1 rotates as a whole, further increasing the number of collisions and exchange positions between the carbon particles and carbon powder in the bin, and greatly improving the mixing effect. Compared with the existing mixing mechanism, the mixing of the utility model is more uniform and sufficient, and the practicality of the batching system is improved.

[0027] The first and second spiral ribbons 11 and 12 are arranged opposite to each other, allowing the carbon particles and carbon powder in the middle and outer regions of the bin to fully exchange under the action of opposite rotation. In addition, ribs can be provided on the surfaces of the first and second spiral ribbons 11 and 12. The ribs are arranged along the extension direction of the first and second spiral ribbons 11 and protrude relative to the surfaces of the first and second spiral ribbons 11 and 12. The protruding ribs not only increase the rigidity of the first and second spiral ribbons 11 and 12, but also squeeze the mixed material, further enhancing the fusion effect between the carbon particles and the carbon powder.

[0028] like Figure 1 and Figure 2 As shown, in order to make the overall movement of the mixing bin 1 further improve the mixing effect, two circular tracks are set, namely the first circular track 2 and the second circular track 3, and the distance between them is set according to α. In application, the mixing bin 1 can be controlled to move on half of the first circular track 2, then enter half of the second circular track 3, then enter the other half of the first circular track 2, and finally move along the other half of the second circular track 3. Because there is a certain angle between adjacent tracks, it avoids the mixed materials in the mixing bin 1 from moving along the same trajectory, thereby improving the mixing effect.

[0029] In addition, the maximum travel positions of the first circular track 2 and the second circular track 3 are offset from each other in the vertical plane. Alternatively, the travel of the second circular track 3 can be set to three-quarters of a circle. Similar to the previous principle, the main purpose is to change the movement trajectory of the mixed materials in the mixing bin 1, and the changing trajectory movement can improve the mixing effect.

[0030] It should be noted that the mixing bin 1 also includes a discharge pipe, which is arranged at the bottom of the mixing bin 1 and has a spiral discharge plate inside. The spiral discharge plate is used to promote the rapid discharge of the mixed material and prevent smaller particles or carbon powder in the mixed material from being adsorbed on the wall of the discharge pipe, resulting in uneven discharge of the mixed material.

[0031] In addition, the aforementioned mixing bin 1 is cylindrical, spherical or ellipsoidal in shape. The specific shape can be selected according to the size range of the material particles in the mixture, the structure of the stirrer and the adaptability to the actual use environment. This embodiment does not impose any specific restrictions on this.

[0032] In some embodiments, the activated carbon configuration system provided by the present invention further includes a hopper truck, which corresponds one-to-one to the plurality of conveyor belts 5 , and the hopper truck is arranged above the initial material transfer position of the conveyor belt 5 .

[0033] In addition, the discharge port of the aforementioned hopper car can also be provided with a screen. The shaking screen can increase the flexibility of the discharge, prevent the discharge from being blocked, and prevent some of the mixed materials in the mixing bin 1 from condensing into lumps, thereby affecting the mixing effect.

[0034] In some embodiments, the combing plate at the front end of the conveyor belt 5 is mounted at a first position and a second position, the first and second positions being parallel to each other. A motor controls the combing plate to reciprocate between the first and second positions. Specifically, the motor causes the combing plate to reciprocate between the first and second positions, vibrating the combing plate to increase the material combing rate while preventing the material from adhering to the surface of the combing plate.

[0035] Finally, the present invention provides an activated carbon configuration system, including a feeding mechanism and a mixing bin 1, wherein the feeding mechanism is connected to the feeding port of the mixing bin 1, the top of the mixing bin 1 includes a driving device, the interior of the mixing bin 1 includes an agitator and a protrusion, the protrusion is protruded relative to the inner wall of the mixing bin 1, the agitator includes a rotating shaft, a first spiral ribbon 11, and a second spiral ribbon, the first spiral ribbon 11 and the second spiral ribbon are both connected to the rotating shaft, the rotating shaft is connected to the driving device, the rotation radius of the first spiral ribbon 11 is smaller than the rotation radius of the second spiral ribbon, and the spiral directions of the first spiral ribbon 11 and the second spiral ribbon are On the contrary, the outer wall of the mixing bin 1 is provided with a slide rail, which is adapted to a track arranged in the lateral direction of the mixing bin 1. The track includes a first circular track 2 and a second circular track 3 arranged in a vertical plane. The first circular track 2 and the second circular track 3 are installed at a preset angle α, and the track is fixed to the bin body support 4. The feeding mechanism includes: a mixing conveyor belt 6 and multiple conveyor belts 5. One end of the conveyor belt 5 is provided with a combing plate. The multiple conveyor belts 5 are evenly arranged above and on both sides of the mixing conveyor belt 6 in the feeding direction. The discharge ends of the multiple combing plates are connected to the mixing conveyor belt 6. This utility model improves the effect of activated carbon mixing and the practicality of the batching system.
