Description

Technical Field

[0001] The utility model relates to the technical field of catalyst processing machinery, in particular to a granulating device for preparing iron-carbon fillers. Background Art

[0002] Spherical iron-carbon fillers are widely used in industrial wastewater treatment operations. The various powder raw materials that make up the iron-carbon fillers are mixed evenly in a mixer after adding adhesives and pore-forming agents, and then made into spheres of uniform size through a spheroidizer, and finally sintered at high temperature. The inventor found that the traditional process of mixing materials with a mixer and making balls with a spheroidizer requires at least two sets of equipment, one set of equipment is a mixer and the other set of equipment is a spheroidizer. This is not only expensive but also requires material transfer, which is time-consuming and laborious during long-term continuous operation; the balls produced by the traditional extrusion and cutting type spheroidizer have defects in appearance, and the balls are not uniformly shaped. There is an urgent need for a granulation device for preparing iron-carbon fillers that can achieve mixing and spheroidization and ensure the shape of the balls. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a granulating device for preparing iron-carbon filler which can realize mixing into balls and ensure the shape of the balls.

[0004] To solve the above technical problems, the utility model includes a frame, the frame is provided with a shaping cover, the shaping cover includes a cover body connected to the frame, the bottom of the cover body is open and the overall diameter gradually increases from bottom to top, the bottom of the cover body is provided with a discharge barrel, the top of the cover body is provided with a connecting ring, the connecting ring is provided with a mixing barrel, the bottom of the mixing barrel is provided with a material port, and also includes a forming disk located below the material port and capable of rotating, the forming disk includes a first disk body for blocking the material port and a second disk body with a plurality of through holes, the top of the mixing barrel is provided with a cover body, the cover body is provided with a rotatable rotating shaft, the rotating shaft is provided with a plurality of stirring frames located in the mixing barrel, the rotating shaft is provided with a scraper located below the forming disk, the side of the scraper close to the rotating shaft is provided with a bearing frame for receiving the material scraped off by the scraper, the rotating shaft is provided with a pushing plate located above the material port and at the front side of the scraper moving direction, the pushing plate is arranged to be inclined forward from bottom to top, and the cover body is provided with at least one feeding barrel.

[0005] After adopting the above structure, the first plate body is rotated to rotate below the material port to complete the blocking of the material port, and the material used to form the iron-carbon filler is put into the mixing barrel and the forming plate through the feeding tube. The rotation of the rotating shaft drives a number of stirring racks, a push plate and a scraper to rotate. After the several stirring racks and the push plate mix the materials evenly, the forming plate is rotated to rotate the second plate body with a number of through holes to below the material port. The rotating stirring rack continues to stir and mix the materials to ensure the state of the materials after mixing. Since the push plate is located in front of the scraper moving direction and is tilted forward from bottom to top, the push plate can give downward pressure to the mixed material, so that the material can fall downward from the through hole of the second plate body under the action of the push plate and gravity, and then the rotating scraper scrapes the material passing through the through hole of the second plate body onto the supporting frame. The material on the carrier is roughly spherical. Under the action of centrifugal force, the balls on the carrier roll along the carrier to achieve primary shaping. The balls roll along the carrier to the high place of the cover body. The balls falling on the cover body have a certain speed, and under the action of gravity, the balls roll from the high place of the cover body to the low place of the cover body until they pass through the discharge barrel to achieve secondary shaping. Finally, the operator can collect the balls from the discharge barrel, thereby achieving mixing into balls and ensuring the shape of the balls.

By providing the first motor and the gear, the rotational force output by the first motor is transmitted to the forming disk through the gear and the teeth on the outer side surface of the forming disk, so that the forming disk can rotate.

[0007] Furthermore, the cross-sectional shape of the support frame is V-shaped. By providing a support frame with a V-shaped cross-sectional shape, it can not only adapt to balls with different diameters but also ensure stable contact between the balls and the support frame, thereby ensuring a one-time shaping effect.

[0008] Furthermore, the vertical distance between the carrier and the forming disk gradually increases from the side close to the rotating shaft to the side away from the rotating shaft. By setting the vertical distance between the carrier and the forming disk, the carrier is tilted as a whole, reducing the possibility of the ball being retained on the carrier.

[0009] Furthermore, the cover body is provided with a second motor, the output end of the second motor is provided with a reduction box, and the rotating shaft is connected to the output end of the reduction box. By providing the second motor and the reduction box, the high speed output by the second motor is reduced by the reduction box to drive the rotating shaft to rotate, which can provide stable power for the rotating shaft.

[0010] Furthermore, the frame is provided with a slideway located below the discharge barrel and arranged obliquely, and the slideway is arranged obliquely downward from a side close to the discharge barrel to a side away from the discharge barrel. By providing the slideway, the convenience of collecting the material balls is improved, and the directional collection of the material balls is achieved.

[0011] Furthermore, the side of the slideway close to the discharge barrel is hinged on the frame, and the frame is provided with a linear drive member located below the slideway and capable of reciprocating up and down at the output end, and the output end of the linear drive member is provided with a rubber pier that can abut against the bottom of the slideway. By providing the linear drive member and the rubber pier, the linear drive member enables the slideway hinged on the frame to swing up and down to prevent the material ball from being retained on the slideway, and the rubber pier prevents the output end of the linear drive member from directly contacting the slideway so that the output end of the linear drive member and the slideway are worn.

[0012] Furthermore, the frame is provided with a plurality of lifting rings, by arranging the lifting rings, the device can be lifted and transported conveniently and safely.

[0013] In summary, the utility model has the advantages of convenient use, reasonable structure, etc. BRIEF DESCRIPTION OF THE DRAWINGS

The cross-sectional shape of the carrier 61 is V-shaped, which can not only adapt to balls of different diameters but also ensure the stable contact between the balls and the carrier 61, thereby ensuring the one-time shaping effect. The vertical distance between the carrier 61 and the forming disc 4 gradually increases from the side close to the rotating shaft 51 to the side away from the rotating shaft 51, and the carrier 61 is tilted as a whole, reducing the possibility of the balls being retained on the carrier 61.
