Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of activated carbon preparation, and particularly relates to a mixing device for activated carbon production. BACKGROUND

[0002] As a kind of porous adsorption material with highly developed pore structure and large specific surface area, activated carbon is widely used in air purification, water treatment, soil remediation, catalyst carrier, energy storage material and many other fields. The adsorption performance of activated carbon not only depends on its own pore structure and surface chemical properties, but also is closely related to the specific functional substances loaded thereon.

[0003] In order to endow activated carbon with specific functions or enhance its adsorption performance, it is usually necessary to uniformly mix activated carbon with various powdery materials. These powders can be inorganic compounds such as calcium carbonate powder, calcium oxide powder, calcium hydroxide powder, etc., which are used to adjust pH value, provide reaction sites or enhance the adsorption capacity for specific pollutants; or can be ceramic powder, etc., which are used to improve the mechanical strength, wear resistance or thermal stability of activated carbon. By effectively mixing activated carbon with specific powders, composite activated carbon materials with specific functions or enhanced adsorption performance can be prepared to meet the needs of different application fields.

[0004] At present, there are mainly two ways for mixing activated carbon and powders: one is mechanical stirring mixing, which is to place activated carbon particles and powders in a closed or open container and mix them by mechanical stirring devices (such as paddle stirrer, screw stirrer, V-type mixer, etc.). During stirring, the powder particles collide and rub with the activated carbon particles under the action of mechanical force, and part of the powder particles will be embedded in the pores of activated carbon or adsorbed on its surface, thereby realizing the combination of the two. The advantages of mechanical stirring mixing are simple equipment, convenient operation and high production efficiency, which is suitable for large-scale production; the other is airflow mixing, which is to place activated carbon particles in a fluidized bed or airflow conveying pipeline, and blow the powders into the airflow by high-speed airflow, so that the powder particles collide and adsorb with the activated carbon particles in the airflow. The advantages of airflow mixing are fast mixing speed and good mixing uniformity, which is suitable for continuous production.

[0005] No matter mechanical mixing or air flow mixing, there is a common defect that the powder not fully combined with activated carbon and the impurities (such as stones, sand particles, etc.) originally existing in the raw materials cannot be effectively separated and recovered. In actual production, due to the influence of the properties of the powder, the properties of the activated carbon, the mixing process parameters and other factors, a part of the powder cannot be effectively combined with the activated carbon particles. These uncombined excess powder and impurities introduced in the mixing process will be mixed with the activated carbon product and leave the factory, which not only reduces the effective ingredient content of the activated carbon product, affects its adsorption performance and use effect, but also causes waste due to the easy falling of the uncombined excess powder and the abrasion of the impurities to the transportation equipment and use equipment, shortening the service life of the equipment.

[0006] In view of the above, the application provides a mixing device for activated carbon production, which can effectively separate the impurities and uncombined excess powder in the initially mixed activated carbon, significantly improve the product purity and effective ingredient content, reduce the powder waste in the transportation and use process, avoid the abrasion of the impurities to the related equipment, effectively separate the powder and impurities in the sieve discharge, realize the recycling of the powder and reduce the waste.

The driving rotating shaft 411 is rotatably sleeved with a driven gear 43 between the two first clamping rings 413. The driven gear 43 is in meshing connection with the driven pinion 422. The number of teeth of the driving gear 421 is greater than that of the driving pinion 412 and the driven pinion 422. The number of teeth of the driven pinion 422 is less than that of the driven gear 43. The driven gear 43 is coaxially fixed with a driven pipe 44 below.

The inner wall surface of the driven pipe 44 is vertically provided with a first long groove 441.

[0037] The motor 41 provides a power source and drives the whole mechanism through the driving rotating shaft 411. The driving pinion 412 and the driving gear 421 constitute a first-stage gear transmission to realize first speed change. The driven pinion 422 and the driven gear 43 constitute a second-stage gear transmission to realize second speed change, so that the rotating speed of the driven gear 43 is much lower than that of the motor 41.

[0039] The design of the horizontal sliding grooves 452 and the inclined sliding grooves 453 enables the sliding column 491 to move along a specific track relative to the round pipe cam 45, so as to control the timing and amplitude of the up-down movement of the round pipe cam 45, the stirring shaft 46 is connected with the round pipe cam 45 through the second clamping ring 461, can move up and down with the round pipe cam 45 and can rotate relative to the round pipe cam 45, the second friction disc 48 is matched with the first friction disc 47 to realize the intermittent rotation of the stirring shaft 46.

[0040] The air passage opening and closing mechanism 6 comprises a third clamping ring 61, a rotating ring 62 and an air inlet 65, the third clamping ring 61 is coaxially and fixedly arranged at a position close to the lower end of the stirring shaft 46, the rotating ring 62 is coaxially and closely arranged on the stirring shaft 46 between the third clamping rings 61, the rotating ring 62 is fixedly arranged with rotating rods 63 on the outer side along the axis in a circumferential array, the sealing plug 64 is horizontally fixedly arranged at one end of the rotating rod 63, the air inlet 65 is arranged on the upper wall of the conical treatment cylinder 1 in a circumferential array along the axis of the conical treatment cylinder 1, the sealing plug 64 is coaxially arranged with the air inlet 65 above and has the same diameter, the rotating rods 63 on both sides are closely arranged with limiting rods 66, the upper ends of the limiting rods 66 are fixedly connected with the upper wall of the conical treatment cylinder 1.

[0042] When the sliding column 491 is located in the horizontal sliding 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 sliding column 491 is located in the inclined sliding 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.

The mesh of the conical mesh cylinder 52 can block the activated carbon particles. The upper end of the stirring pipe 53 penetrates through the mounting rod 51 vertically. A fourth clamping ring 54 is fixedly arranged on the upper end of the stirring pipe 53 coaxially and is spaced apart.

The stirring pipe 53 is annularly distributed with stirring rods 57 along the axial direction. The spacing between the ends of all the stirring rods 57 and the inner wall of the conical mesh cylinder 52 is equal.

[0044] The mounting rod 51 provides support for the stirring pipe 53 and the conical mesh cylinder 52. The conical mesh cylinder 52 is used for containing activated carbon particles. The mesh size should be selected to effectively block the activated carbon particles while allowing the powder and impurities to pass through. The stirring pipe 53 is connected with the mounting rod 51 through the fourth clamping ring 54 and can only rotate relatively. The second clamping block 56 transmits the rotation of the stirring shaft 46 to the stirring pipe 53 through the cooperation with the second long groove 55.

The disc 72 covers the bottom of the conical mesh cylinder 52. A handle 73 is fixedly arranged on one side of the disc 72.

[0046] The semicircular clamping ring 71 and the disc 72 constitute an openable and closable structure of 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 needed, the disc 72 is pulled out of the semicircular clamping ring 71 through the handle 73 to open the bottom of the conical mesh cylinder 52, so that the treated activated carbon mixture is discharged.

[0047] The air inlet mechanism 8 comprises air inlet sub-pipes 81 distributed above the air inlet 65 and fixedly communicated with the upper wall of the conical processing cylinder 1, and all the upper ends of the air inlet sub-pipes 81 are jointly communicated with an air inlet main pipe 82 which is always filled with pressurized air.

[0048] The cross section of the spiral guide ring 2 is obliquely upward long strip, the spiral guide ring 2 is spaced apart from the conical mesh cylinder 52 and covers the conical mesh cylinder 52, and the air inlet 65 is opposite to the space between the conical mesh cylinder 52 and the conical processing cylinder 1.

[0049] The cross section of the spiral guide ring 2 is obliquely upward long strip, the spiral guide ring 2 is spaced apart from the conical mesh cylinder 52 and covers the conical mesh cylinder 52, and the air inlet 65 is opposite to the space between the conical mesh cylinder 52 and the conical processing cylinder 1.

[0050] The cross section of the spiral guide ring 2 is obliquely upward long strip, the spiral guide ring 2 is spaced apart from the conical mesh cylinder 52 and covers the conical mesh cylinder 52, and the air inlet 65 is opposite to the space between the conical mesh cylinder 52 and the conical processing cylinder 1.

[0051] The second sealing door 12 is closed in normal operation to prevent gas leakage, the feeding hopper 13 is used to add the initially mixed activated carbon particles into the conical mesh cylinder 52, the first sealing door 14 also maintains the airtightness of the conical processing cylinder 1, and the collection box 15 is used to collect the impurities falling from the spiral guide ring 2, and the collection box 15 is tightly arranged with the side wall of the conical processing cylinder 1 to prevent the impurities from falling into other places.

[0052] The specific working process is as follows:

[0053] First, confirm that the second sealing door 12 is closed, open the first sealing door 14 on the feeding hopper 13, pour the activated carbon particles (including activated carbon, unbound excess powder and sand impurities) after preliminary mixing into the feeding hopper 13, and the material will directly fall into the conical mesh cylinder 52, after the feeding is completed, the first sealing door 14 is closed, and the airtight state of the conical processing cylinder 1 is restored.

[0054] The motor 41 is started, and the pressurized air is continuously injected into the air inlet pipe 82. The power of the motor 41 is transmitted through the driving shaft 411 to drive the whole mechanism. The driving shaft 411 drives the driving pinion 412 to rotate. The driving pinion 412 is engaged with the driving gear 421. The driving gear 421 drives the driven shaft 42 to rotate. The driven pinion 422 on the driven shaft 42 is engaged with the driven gear 43. Since the number of teeth of the driving gear 421 is greater than the number of teeth of the driving pinion 412 and the driven pinion 422, and the number of teeth of the driven pinion 422 is less than the number of teeth of the driven gear 43, the rotation speed of the driven gear 43 is much lower than the output rotation speed of the motor 41. The driven gear 43 drives the driven pipe 44 fixed coaxially therewith to rotate. The driven pipe 44 drives the circular pipe cam 45 to rotate. Since the first clamping block 451 is in close sliding fit with the first long groove 441, the circular pipe cam 45 can slide up and down in the driven pipe 44. When the slide rod 491 is located in the horizontal sliding groove 452, the circular pipe cam 45 is at a higher position. The first friction disc 47 at the lower end of the driving shaft 411 is in close contact with the second friction disc 48 at the upper end of the stirring shaft 46. The first friction disc 47 drives the second friction disc 48 to rotate through friction, and in turn drives the stirring shaft 46 to rotate. The rotation of the stirring shaft 46 is transmitted to the stirring pipe 53 through the second long groove 55 and the second clamping block 56 at the upper end of the inner wall of the stirring pipe 53. The stirring pipe 53 drives the stirring rod 57 to rotate, and the activated carbon mixture in the conical mesh cylinder 52 is subjected to high-speed stirring. At the same time, the third clamping ring 61 on the stirring shaft 46 limits the axial movement of the rotating ring 62, and drives the sealing plug 64 to be at a higher position through the rotating rod 63 to close the air inlet 65. At this time, the pressurized air injected by the air inlet pipe 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. The excess powder and sand impurities that are not fully combined with the activated carbon are thrown out by centrifugal force. The impurity particles such as stones and sand that are relatively heavy 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. When the slide rod 491 is located in the inclined sliding groove 453, the circular pipe cam 45 gradually moves downward under the guidance of the slide rod 491. The first friction disc 47 is separated from the second friction disc 48. The stirring shaft 46 stops rotating, and the stirring rod 57 stops stirring. The third clamping ring 61 drives the rotating ring 62 and the rotating rod 63 to move downward, and the sealing plug 64 is separated from the air inlet 65. The pressurized air injected by the air inlet pipe 82 enters the conical treatment cylinder 1 through the air inlet branch pipe 81 and the air inlet 65, and directly blows 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, and the possibility that the impurities are carried away by the airflow halfway is avoided. The above two processes are alternately performed to realize efficient impurity separation and purification of the activated carbon mixture.Meanwhile, the pure and impurity-free powder gas can be injected into a new primary mixing device through the gas outlet pipe 9 to mix with the activated carbon, thereby realizing powder recycling.

[0055] In order to realize automatic monitoring of whether the excess powder and impurities have been sufficiently screened out, in the prior art, a sound sensor, such as a piezoelectric acoustic emission sensor, can be arranged on the inner wall of the conical processing cylinder 1 to monitor the sound of the impurities colliding with the inner wall of the conical processing cylinder 1, and a dust sensor, such as a laser scattering type dust concentration sensor, can be arranged at the inlet of the gas outlet pipe 9 to monitor the concentration of the powder gas, which is the prior art known to those skilled in the art and is not the key technical solution, so it will not be described in detail. When the sound sensor does not monitor the collision sound and the dust sensor does not monitor the powder in the gas, it indicates that the separation process has been completed, the motor 41 is turned off, the stirring is stopped, and the injection of the pressurized air is stopped. The second sealing door 12 on the outside of the conical processing cylinder 1 is opened, a material guiding device, such as an inclined material guiding groove, is prepared, which is inclined upward and extends into the lower part of the conical mesh cylinder 52, the disc 72 is pulled out of the semi-circular clasp 71 through the handle 73, the bottom of the conical mesh cylinder 52 is opened, and the purified activated carbon mixture is discharged under the action of gravity through the material guiding device. According to the accumulation of impurities in the collection box 15, the collection box 15 is cleaned regularly to ensure the normal operation of the device.
