Description

Technical Field

[0001] The invention belongs to the technical field of activated carbon preparation, and in particular relates to a mixing device for activated carbon production. Background Art

[0002] Activated carbon, a porous adsorption material with a highly developed pore structure and a large specific surface area, is widely used in a wide range of fields, including air purification, water treatment, soil remediation, catalyst support, and energy storage materials. The adsorption performance of activated carbon depends not only on its pore structure and surface chemical properties, but also on the specific functional substances it carries.

[0003] To impart specific functions or enhance its adsorption properties, activated carbon is typically uniformly mixed with various powdered materials. These powders can be inorganic compounds, such as calcium carbonate, calcium oxide, and calcium hydroxide powders, used to adjust pH, provide reaction sites, or enhance the adsorption capacity of specific pollutants. They can also be ceramic powders, used to improve the mechanical strength, wear resistance, or thermal stability of the activated carbon. By effectively mixing activated carbon with specific powders, composite activated carbon materials with specialized functions or enhanced adsorption properties can be prepared to meet the needs of diverse applications.

[0004] Currently, there are two main methods for mixing activated carbon with powder. One is mechanical mixing, in which activated carbon granules and powder are placed in a closed or open container and forced to mix using a mechanical stirring device (such as a paddle mixer, ribbon mixer, or V-type mixer). During the mixing process, the powder particles collide and rub against the activated carbon particles under the action of mechanical force. Some of the powder particles become embedded in the pores of the activated carbon or adsorb onto its surface, thus forming a bond between the two. Mechanical mixing offers the advantages of simple equipment, easy operation, and high production efficiency, making it suitable for large-scale production. The other method is airflow mixing, in which activated carbon granules are placed in a fluidized bed or air conveying pipe and the powder is blown in via a high-speed airflow, causing the powder and activated carbon particles to collide and adsorb in the airflow. Airflow mixing offers the advantages of fast mixing speed and good mixing uniformity, making it suitable for continuous production.

[0005] Whether mechanically agitated or air-flow mixing, both methods share a common drawback: the inability to effectively separate and recover powder that hasn't fully bonded to the activated carbon, as well as impurities already present in the raw materials (such as gravel and sand). In actual production, due to factors such as the properties of the powder, the properties of the activated carbon, and the mixing process parameters, some powder will fail to effectively bond with the activated carbon particles. This unbound excess powder, along with impurities introduced during the mixing process, is mixed with the activated carbon product before shipment. This not only reduces the active ingredient content of the activated carbon product, affecting its adsorption properties and effectiveness, but also easily falls off during transportation and use, resulting in waste. The impurity particles can also wear and tear on transportation and handling equipment, shortening its lifespan. Summary of the Invention

[0006] In response to the above situation, the present invention provides a mixing device for activated carbon production, which can effectively separate impurities and uncombined excess powder in the activated carbon after initial mixing, significantly improve the product purity and effective ingredient content, reduce powder waste during transportation and use, and avoid the wear of related equipment by impurities. It can also effectively separate the powder and impurities in the screened material, realize powder recycling and reduce waste.

The cooperation of the circular tube cam, the slide column, the horizontal slide groove, the inclined slide groove, the first friction disc and the second friction disc is used to realize the cyclic switching of the two key processes. When the slide column is located in the horizontal slide groove, the first friction disc contacts the second friction disc, driving the stirring shaft, the stirring tube and the stirring rod to rotate at high speed, stirring the activated carbon mixture in the conical mesh cylinder, and the excess powder and impurities are thrown out under the action of centrifugal force. When the slide column is located in the inclined slide groove, the first friction disc separates from the second friction disc, stirring stops, the sealing plug separates from the air inlet, and compressed air enters the conical treatment cylinder to discharge the dispersed powder through the outlet pipe. The stirring stops and also prevents the continuously thrown impurities from being carried away by the air flow halfway.

[0018] (2) This device effectively separates excess powder and impurities in the activated carbon after initial mixing through the synergistic effect of intermittent stirring and air flow separation. The heavier impurities slide along the spiral guide ring to the collection box, and the lighter powder is discharged through the outlet pipe under the action of the air flow. This significantly improves the purity and effective ingredient content of the activated carbon product. The pure powder gas discharged through the outlet pipe can be reused, reducing waste and complying with the concept of environmental protection.

[0019] (3) This device uses only one motor as the power source. Through the ingenious design of the differential intermittent clutch drive mechanism, it can simultaneously realize the driving of the two functions of stirring and airway opening and closing. This not only simplifies the structure of the device and reduces the manufacturing cost, but also reduces energy consumption and improves the reliability of the equipment and the convenience of maintenance.

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown, the present invention proposes a mixing device for activated carbon production, comprising a conical treatment barrel 1, which is suspended and fixed by a bracket, and the lower end of the conical treatment barrel 1 is a tightening end, and a spiral guide ring 2 is spirally fixed along the axis of the inner wall of the conical treatment barrel 1, and a mounting cover 3 is coaxially fixed on the upper side of the conical treatment barrel 1, and a differential intermittent clutch drive mechanism 4 is coaxially provided inside the mounting cover 3, and a stirring mechanism 5 is coaxially provided at the lower end of the differential intermittent clutch drive mechanism 4, and an airway opening and closing mechanism 6 is coaxially provided between the differential intermittent clutch drive mechanism 4 and the stirring mechanism 5, and the airway opening and closing mechanism 6 and the stirring mechanism 5 are located inside the conical treatment barrel 1, and a unloading mechanism 7 is provided on the lower side of the stirring mechanism 5, and an air intake mechanism 8 is connected to the periphery of the mounting cover 3 on the upper side of the conical treatment barrel 1, and an air outlet pipe 9 is fixedly connected to the lower side of the conical treatment barrel 1.

[0035] Among them, the differential intermittent clutch drive mechanism 4 includes a motor 41 and a driven shaft 42. The motor 41 is fixed on the upper side of the upper wall of the mounting cover 3. The output end of the motor 41 facing downward is coaxially fixed with a driving shaft 411. After the driving shaft 411 extends into the interior of the mounting cover 3, it is coaxially fixed with a driving pinion 412. The upper end of the driven shaft 42 is vertically engaged and rotated on the upper wall of the mounting cover 3. The driven shaft 42 is coaxially fixed with a driving large gear 421 and a driven small gear 422 in the mounting cover 3. The driven small gear 422 is located below the driving large gear 421. The driving large gear 421 is meshed with the driving small gear 412. The driving shaft 411 is in the driving small gear. A first retaining ring 413 is coaxially fixed at intervals below 412, and a driven large gear 43 is tightly and rotatably sleeved on the driving shaft 411 between the two first retaining rings 413. The driven large gear 43 is meshed with the driven small gear 422. The number of teeth of the driving large gear 421 is greater than the number of teeth of the driving small gear 412 and the driven small gear 422, and the number of teeth of the driven small gear 422 is less than the number of teeth of the driven large gear 43. A driven tube 44 is coaxially fixed to the lower side of the driven large gear 43, and a first friction disk 47 is coaxially fixed to the lower end of the driving shaft 411. The first friction disk 47 is located in the driven tube 44, and a first long groove 441 is vertically opened on the inner wall surface of the driven tube 44.

[0036] The motor 41 provides a power source, and drives the entire mechanism to operate through the active rotating shaft 411. The active small gear 412 and the active large gear 421 constitute the first-stage gear transmission to achieve the first speed change. The driven small gear 422 and the driven large gear 43 constitute the second-stage gear transmission to achieve the second speed change, so that the speed of the driven large gear 43 is much lower than the output speed of the motor 41. The first retaining ring 413 is used to limit the axial movement of the driven large gear 43. The driven tube 44 is fixedly connected to the driven large gear 43 to transmit the rotation to the circular tube cam 45 below. The first friction disk 47 is a key component for achieving intermittent clutching, and is used to control the start and stop of the stirring mechanism 5. The first long groove 441 is used to guide the up and down movement of the circular tube cam 45.

[0037] Among them, the differential intermittent clutch drive mechanism 4 also includes a circular tube cam 45, a boom 49 and a stirring shaft 46. The circular tube cam 45 is coaxially and tightly slidably arranged in the driven tube 44. A first clamping block 451 is fixedly provided on the upper end of the circular tube cam 45. The first clamping block 451 is tightly and slidably connected with the first long groove 441. A horizontal slide groove 452 and an inclined slide groove 453 are opened on the surface of the circular tube cam 45. The inclined slide groove 453 is located above the horizontal slide groove 452. The inclined slide grooves 453 are symmetrically arranged and connected to each other. The two ends of the horizontal slide groove 452 are respectively connected to the two inclined slide grooves 453. The suspension rod 49 is vertically fixed on the lower side of the upper wall of the mounting cover 3, and a sliding column 491 is horizontally fixed on the lower end of the suspension rod 49. One end of the sliding column 491 points to the axis of the circular tube cam 45 and is tightly and slidingly connected with the horizontal slide groove 452 and the inclined slide groove 453. The stirring shaft 46 is coaxially arranged inside the circular tube cam 45, and a second retaining ring 461 is coaxially fixed at an interval in the middle of the stirring shaft 46. The stirring shaft 46 is rotatably connected to the lower wall of the circular tube cam 45 through the second retaining ring 461. A second friction disk 48 is coaxially fixed on the upper end of the stirring shaft 46, and the lower end of the stirring shaft 46 extends out of the circular tube cam 45.

[0038] The design of the horizontal slide groove 452 and the inclined slide groove 453 enables the slide column 491 to move relative to the circular tube cam 45 along a specific trajectory, thereby controlling the timing and amplitude of the up and down movement of the circular tube cam 45. The stirring shaft 46 is connected to the circular tube cam 45 through the second retaining ring 461, and can move up and down with the circular tube cam 45, and can rotate relative to the circular tube cam 45. The second friction disk 48 cooperates with the first friction disk 47 to realize intermittent rotation of the stirring shaft 46.

[0039] Among them, the airway opening and closing mechanism 6 includes a third clamping ring 61, a rotating ring 62 and an air inlet 65. The third clamping ring 61 is coaxially fixed at a position near the lower end of the stirring shaft 46. The stirring shaft 46 is coaxially and tightly sleeved with a rotating ring 62 between the third clamping ring 61. A rotating rod 63 is fixed on the outer side of the rotating ring 62 along its axial circumferential array. A sealing plug 64 is horizontally fixed at one end of the rotating rod 63. The air inlet 65 is opened on the upper wall of the conical treatment cylinder 1 along the axial circumferential array of the conical treatment cylinder 1. The sealing plug 64 is coaxially arranged with the upper air inlet 65 and has the same diameter. A limiting rod 66 is tightly provided on both sides of one of the rotating rods 63, and the upper end of the limiting rod 66 is fixedly connected to the upper wall of the conical treatment cylinder 1.

[0040] The third retaining ring 61 is used to limit the axial movement of the swivel 62, and drives the swivel 62 to move up and down with the stirring shaft 46, and can also rotate relative to the stirring shaft 46. The rotating rod 63 and the sealing plug 64 constitute the switch of the airway. The function of the limit rod 66 is to prevent the swivel 62 from circumferential displacement when the stirring shaft 46 rotates, and to ensure the accurate alignment of the sealing plug 64 and the air inlet 65.

[0041] Among them, when the slide column 491 is located in the horizontal slide groove 452, the first friction disc 47 and the second friction disc 48 are tightly attached and the sealing plug 64 closes the air inlet 65. When the slide column 491 is located in the inclined slide groove 453, the first friction disc 47 and the second friction disc 48 are separated and the sealing plug 64 is separated from the air inlet 65.

[0042] Among them, the stirring mechanism 5 includes a mounting rod 51, a stirring tube 53 and a second long groove 55. The two ends of the mounting rod 51 are horizontally fixed on the inner wall of the conical treatment cylinder 1. A conical mesh cylinder 52 is fixed on the lower side of the middle of the mounting rod 51. The conical mesh cylinder 52 is coaxial with the conical treatment cylinder 1 and is spaced apart inside the conical treatment cylinder 1. The taper of the conical mesh cylinder 52 is equal to the taper of the conical treatment cylinder 1. The upper and lower ends of the conical mesh cylinder 52 are open. The grid of the conical mesh cylinder 52 can block the activated carbon particles. The upper end of the stirring tube 53 is vertically fixed to the inner wall of the conical treatment cylinder 1. The mounting rod 51 is passed through, and a fourth clamping ring 54 is coaxially fixed at the upper end of the stirring tube 53 at intervals. The stirring tube 53 is rotatably connected to the mounting rod 51 through the fourth clamping ring 54. A second clamping block 56 is fixed at the upper end of the inner wall of the stirring tube 53. The second long groove 55 is vertically opened on the side of the lower end of the stirring shaft 46. The second clamping block 56 is always tightly and slidingly connected to the second long groove 55. The stirring tube 53 is annularly distributed with stirring rods 57 along the axial direction, and the distance between the ends of all stirring rods 57 and the inner wall of the conical mesh cylinder 52 is equal.

[0043] The mounting rod 51 provides support for the stirring tube 53 and the conical mesh tube 52. The conical mesh tube 52 is used to accommodate activated carbon particles. The mesh size should be selected to effectively block the activated carbon particles while allowing powder and impurities to pass through. The stirring tube 53 is connected to the mounting rod 51 through the fourth clamping ring 54 and can only rotate relative to each other. The second clamping block 56 cooperates with the second long groove 55 to transmit the rotation of the stirring shaft 46 to the stirring tube 53. The stirring rod 57 is used to stir the activated carbon particles in the conical mesh tube 52 and throw out excess powder and impurities. The distance between the stirring rod 57 and the inner wall of the conical mesh tube 52 is equal, which ensures the uniformity of stirring.

[0044] Among them, the unloading mechanism 7 includes a semicircular clamping ring 71 and a disc 72. The semicircular clamping ring 71 is fixedly arranged at the lower end of the conical mesh cylinder 52. The disc 72 is tightly attached to the bottom of the conical mesh cylinder 52 and is slidably connected to the semicircular clamping ring 71. The disc 72 covers the bottom of the conical mesh cylinder 52. A handle 73 is fixedly provided on one side of the disc 72.

[0045] The semicircular retaining ring 71 and the disc 72 constitute an openable and closable structure at the bottom of the conical mesh cylinder 52. During normal operation, the disc 72 closes the bottom of the conical mesh cylinder 52 to prevent material leakage. When unloading is required, the disc 72 is pulled out of the semicircular retaining ring 71 through the handle 73 to open the bottom of the conical mesh cylinder 52 and discharge the treated activated carbon mixture.

[0046] Among them, the air intake mechanism 8 includes an air intake branch pipe 81, which is distributed above the air inlet 65 and fixedly connected to the upper wall of the conical treatment cylinder 1. The upper ends of all the air intake branch pipes 81 are commonly connected to the air intake main pipe 82, and the air intake main pipe 82 is always injected with compressed air.

[0047] The cross section of the spiral guide ring 2 is an upwardly inclined long strip. The spiral guide ring 2 is spaced apart from the conical mesh cylinder 52 and covers the conical mesh cylinder 52 . The air inlet 65 faces the space between the conical mesh cylinder 52 and the conical treatment cylinder 1 .

[0048] The cross section of the spiral guide ring 2 is designed to be tilted upward to prevent impurities from falling out, and can gradually slide down along the spiral guide ring 2. The position design of the air inlet 65 allows the air flow to blow directly into the space between the conical mesh tube 52 and the conical processing tube 1, effectively blowing the dispersed powder to the air outlet pipe 9 below.

[0049] Among them, a feeding port 11 is opened on the outside of the conical treatment cylinder 1 below the spiral guide ring 2, and a second sealing door 12 is hinged on the feeding port 11. A feed hopper 13 is fixedly provided on the upper side of the upper wall of the conical treatment cylinder 1. The feed hopper 13 faces the inside of the conical mesh cylinder 52, and a first sealing door 14 is hinged on the feed hopper 13. A collecting box 15 is placed on the lower wall of the conical treatment cylinder 1. The collecting box 15 is located directly below the tail of the lower end of the spiral guide ring 2, and the collecting box 15 is tightly arranged against the side wall of the conical treatment cylinder 1.

[0050] The second sealing door 12 is closed during normal operation to prevent gas leakage. The feed hopper 13 is used to add the activated carbon particles of the initial mixing into the conical mesh tube 52. The first sealing door 14 also maintains the airtightness of the conical treatment tube 1. The collection box 15 is used to collect impurities that slide down from the spiral guide ring 2. The collection box 15 is in close contact with the side wall of the conical treatment tube 1 to prevent impurities from falling into other places.

[0051] The specific working process is as follows: First, confirm that the second sealed door 12 is closed, open the first sealed door 14 on the feed hopper 13, and pour the preliminarily mixed activated carbon particles (including activated carbon, uncombined excess powder and sand and gravel impurities) into the feed hopper 13. The material will fall directly into the conical mesh cylinder 52. After the feeding is completed, close the first sealed door 14 and restore the closed state of the conical treatment cylinder 1.

[0052] Start the motor 41 and continuously inject pressurized air into the intake manifold 82. The power of the motor 41 is transmitted through the driving shaft 411 to drive the entire mechanism to operate. The driving shaft 411 drives the driving pinion 412 to rotate. The driving pinion 412 meshes with the driving large gear 421. The driving large gear 421 drives the driven shaft 42 to rotate. The driven pinion 422 on the driven shaft 42 meshes with the driven large gear 43. Since the number of teeth of the driving large gear 421 is greater than that of the driving pinion 412 and the driven pinion 422, and the number of teeth of the driven pinion 422 is less than that of the driven large gear 43, under this gear ratio, the speed of the driven large gear 43 is much lower than the output speed of the motor 41. The driven large gear 43 drives the driven pipe 43 fixed coaxially therewith. 44 rotates, the driven tube 44 drives the circular tube cam 45 to rotate, and since the first block 451 is in close sliding cooperation with the first long groove 441, the circular tube cam 45 can slide up and down in the driven tube 44. When the slide column 491 is located in the horizontal slide groove 452, the circular tube cam 45 is in a higher position, and the first friction disk 47 at the lower end of the active rotating shaft 411 is in close contact with the second friction disk 48 at the upper end of the stirring shaft 46. The first friction disk 47 drives the second friction disk 48 to rotate through friction, and then drives the stirring shaft 46 to rotate. The rotation of the stirring shaft 46 is transmitted to the stirring tube 53 through the cooperation between the second long groove 55 and the second block 56 at the upper end of the inner wall of the stirring tube 53. The stirring tube 53 drives the stirring rod 57 to rotate, so as to stir the activated carbon mixture in the conical mesh cylinder 52. High-speed stirring is performed, and at the same time, the third clamping ring 61 on the stirring shaft 46 limits the axial movement of the rotating ring 62, and the sealing plug 64 is in a higher position through the rotating rod 63 to close the air inlet 65. At this time, the pressurized air injected by the air intake manifold 82 cannot enter the conical treatment cylinder 1. During the stirring process, under the action of centrifugal force, the activated carbon particles diffuse along the side wall of the conical mesh cylinder 52, and the excess powder and sand and gravel impurities that are not fully combined with the activated carbon are centrifugally thrown out. The heavier impurity particles such as gravel and sand are thrown to the inner wall of the conical treatment cylinder 1 and fall onto the spiral guide ring 2, gradually slide down along the spiral guide ring 2, and finally fall into the collection box 15. The lighter powder is dispersed in the space between the conical mesh cylinder 52 and the conical treatment cylinder 1. The slide column 491 is located on the inclined slide When the groove 453 is reached, the circular tube cam 45 gradually moves downward under the guidance of the sliding column 491, the first friction disc 47 separates from the second friction disc 48, the stirring shaft 46 stops rotating, the stirring rod 57 stops stirring, and the third clamping ring 61 drives the rotating ring 62 and the rotating rod 63 to move downward, the sealing plug 64 separates from the air inlet 65, and the pressurized air injected by the intake manifold 82 enters the conical treatment cylinder 1 through the intake branch pipe 81 and the air inlet 65, and blows directly to the space between the conical mesh cylinder 52 and the conical treatment cylinder 1. The airflow presses the dispersed powder downward and discharges it through the air outlet pipe 9. Since the stirring stops at this time, the impurities are no longer thrown out, avoiding the possibility of the impurities being carried away by the airflow halfway. The above two processes are performed alternately to achieve efficient impurity separation and purification of the activated carbon mixture.At the same time, the pure powder gas without impurities can be injected into the new primary mixing device through the outlet pipe 9 to mix the activated carbon and realize the reuse of the powder.

[0053] In order to realize automatic monitoring of whether excess powder and impurities have been fully screened out, in the prior art, a sound sensor, such as a piezoelectric acoustic emission sensor, can be optionally provided on the inner wall of the conical treatment cylinder 1 to monitor the sound of impurities colliding with the inner wall of the conical treatment cylinder 1, and a dust sensor, such as a laser scattering dust concentration sensor, can be provided at the inlet of the outlet pipe 9 to monitor the concentration of the powder gas. This is a prior art well known to those skilled in the art and is not a key technical solution, so it will not be described in detail. When the sound sensor monitors the absence of collision sound and the dust sensor monitors the absence of powder in the gas, When the material is filled, it indicates that the separation process is completed, turn off the motor 41, stop stirring, and stop injecting pressurized air. Open the second sealing door 12 on the outside of the conical treatment cylinder 1, prepare a material guiding device, such as an inclined material guiding trough, and extend it obliquely upward under the conical mesh cylinder 52. Use the handle 73 to pull the disc 72 out of the semicircular clamping ring 71, open the bottom of the conical mesh cylinder 52, and the purified activated carbon mixture is discharged through the material guiding device under the action of gravity. According to the accumulation of impurities in the collecting box 15, clean the collecting box 15 regularly to ensure the normal operation of the device.
