Description

Technical Field

[0001] This utility model belongs to the technical field of granulation equipment, specifically relating to a powdered activated carbon granulation device. Background Technology

[0002] Activated carbon is amorphous carbon that has undergone activation treatment. It is available in powder, granular, or pellet form and has strong adsorption capacity. The activation treatment removes various oils and impurities from the surface of the amorphous carbon, increasing its pore number, surface area, and surface activity, thereby enabling it to adsorb many gases, liquids, or certain solutes in solutions.

[0003] The processing of activated carbon involves turning powdered activated carbon into granules of specific shapes and sizes; this process is called activated carbon granulation. Granulated activated carbon has higher mechanical strength and wear resistance, can withstand greater pressure without easily breaking, which greatly extends its service life and reduces dust generation during use.

[0004] However, existing activated carbon granulation equipment is inconvenient for screening and requires a large number of drive sources, which not only increases production and maintenance costs but also makes the control system more difficult to construct, hindering its practical application. Therefore, there is an urgent need for a powdered activated carbon granulation device.

[0005] A patent with publication number CN217126929U discloses a granulation device for powdered activated carbon. This device includes a drive motor, screw, granulation disc, pneumatic telescopic rod, servo motor, cutter, cam, and sieve. In operation, the drive motor rotates the extrusion screw to extrude the powdered activated carbon raw material into strips, which are then extruded through the granulation disc. During operation, the pneumatic telescopic rod and servo motor are activated. The pneumatic telescopic rod drives the cutter to move up and down to cut the strips, while the servo motor drives the cam to rotate, causing the sieve to vibrate up and down to improve the sieving effect.

[0006] However, the above solution requires not only activating the pneumatic telescopic rod to drive the cutter up and down to cut the strip-shaped material, but also activating the servo motor to drive the cam to rotate, causing the screen bucket to vibrate up and down to improve the screening effect. The entire process requires multiple drive sources, which not only increases production and maintenance costs but also increases the complexity of the control system construction, making it difficult to promote and use in practice. Utility Model Content

[0007] To address the problems existing in the background technology, this utility model provides a powdered activated carbon granulation device.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A powdered activated carbon granulation device includes a conveying mechanism and a fixed frame. The output end of the conveying mechanism is fixedly equipped with a granulation orifice plate and a protective frame. A cutting blade is rotatably mounted on the granulation orifice plate facing the protective frame. A discharge port is opened at the bottom of the protective frame. A sliding frame reciprocates horizontally at the top of the fixed frame. An inclined filter screen is integrally fixed at the bottom of the sliding frame. The higher end of the filter screen is located below the discharge port, and a recycling box is placed below the lower end of the filter screen. A driving mechanism acting on the cutting blade is provided on the fixed frame, and the driving mechanism acts on the sliding frame through a transmission component.

[0010] Furthermore, the feeding mechanism includes an extrusion cylinder, with a feed cylinder fixedly connected to the top of the extrusion cylinder; an auger is rotatably arranged inside the extrusion cylinder, and a first motor is fixedly installed on the outer surface of the extrusion cylinder, with the output shaft of the first motor coaxially and fixedly connected to one end of the auger's built-in rotating shaft.

[0011] Furthermore, several support legs are fixedly provided at the bottom of the extrusion cylinder.

[0012] Furthermore, a collection box is placed on top of the fixing frame, and the collection box is located below the sliding frame.

[0013] Furthermore, the drive mechanism includes a second motor. The second motor is fixedly mounted on the protective frame, and a rotating shaft is rotatably installed through it. The output shaft of the second motor is fixedly equipped with a first gear. One end of the rotating shaft is fixedly connected to several cutting blades, and the other end of the rotating shaft is fixedly fitted with a second gear. The second gear meshes with the first gear for transmission.

[0014] Furthermore, the transmission component includes a connecting plate, a connecting plate fixedly mounted on the top of the sliding frame, and a limiting frame integrally fixedly mounted in the middle of the connecting plate; a mating rod is fixedly and eccentrically mounted on one side of the first gear, and the mating rod is limited and slidably mounted within the limiting frame.

[0015] This application has the following beneficial effects:

[0016] 1. In this application, during the cutting process where the drive mechanism drives the cutting blade to rotate, the sliding frame and the filter screen will automatically slide back and forth with the assistance of the transmission components, thereby improving the screening effect. No additional drive source is required during the entire process, which reduces production and maintenance costs while lowering the construction difficulty of the control system, making it more conducive to practical promotion and use.

[0017] 2. In this application, by setting an inclined filter screen, the granular activated carbon on the top of the filter screen that does not meet the screening requirements can automatically slide into the recovery box, thereby avoiding the problem of poor screening effect caused by large-sized granular activated carbon remaining on the surface of the filter screen, and further improving the practical effect of this application.

The output shaft of the first motor 3 is coaxially and fixedly connected to one end of the internal rotating shaft of the auger 4.

[0028] The top of the fixed frame 17 is equipped with a sliding frame 12 that slides back and forth in a horizontal direction. The bottom of the sliding frame 12 is integrally fixed with an inclined filter screen 13. The higher end of the filter screen 13 is located below the discharge port, and the lower end of the filter screen 13 is placed below the recycling box 18.

[0029] Furthermore, a collection box is placed on top of the mounting bracket 17, and the collection box is located below the sliding frame 12.

[0030] The fixed frame 17 is equipped with a drive mechanism that acts on the cutting blade 16, and the drive mechanism acts on the sliding frame 12 through a transmission component.

[0031] The drive mechanism includes a second motor 7. The second motor 7 is fixedly mounted on the protective frame 6, and a rotating shaft 15 is rotatably installed through it. The output shaft of the second motor 7 is fixedly mounted with a first gear 8.
