Description

[Technical field]

[0001] The utility model relates to the technical field of granulators, and more specifically, to a novel extrusion gear type granulator. [Background technology]

[0002] Extrusion granulator is a dry granulation process that uses pressure to agglomerate solid materials. This is done by squeezing the material through two counter-rotating rollers driven by an eccentric sleeve or a hydraulic system. When the solid material is squeezed, the air between the powder particles is first expelled to rearrange the particles to eliminate the gaps between the materials.

[0003] An existing granulator for producing particles, publication number: CN 116571168 A, comprises: a processing box, an extrusion roller, a digging plate, a fixed roller and a movable top shaft, the extrusion roller is arranged along the width direction of the processing box, there are two extrusion rollers, the surface of the extrusion roller is provided with a plurality of arc plates, the arc plates on the two extrusion rollers correspond to each other to form an extrusion groove, the digging plate is slidingly arranged on the opposite side of the arc plates on the two extrusion rollers, the movable top shaft slides radially between the fixed roller and the extrusion roller along the fixed roller, and the movable top shaft is connected to the digging plate. This kind of granulator is extruded and formed by a pair of extrusion rollers, but a large amount of heat is generated during long-term operation, which affects the processing effect of the material, and the friction loss increases, which will cause damage to the extrusion roller, reduce the service life of the device, and increase the use cost. An existing ring die granulator, publication number: CN 113908768 A, comprises a frame and a forming drum, the forming drum is densely covered with forming holes which penetrate inside and outside, a roller main shaft driven by a roller driving device is installed in the forming drum, a roller group which cooperates with the forming drum to form ceramsite is installed on the roller main shaft, a scraper which can fit the outer wall of the forming drum is connected to the frame, the forming drum and the roller main shaft rotate in opposite directions, an annular feeding port is opened on the front side of the forming drum, a feeding drum located on one side of the forming drum is installed on the frame, a feeding port is provided on the feeding drum, a feeding screw is installed in the feeding drum, the main shaft of the feeding screw is coaxially arranged with the roller main shaft and connected by a coupling, a guide drum which is arranged in a conical shape is installed between the discharge end of the feeding drum and the feeding port, the guide drum is fixedly connected to the outer wall of the forming drum and the guide drum and the feeding drum are rotatably sealed and connected. The extrusion friction between the forming drum and the pressure roller of the ring die granulator will cause more energy to be required to maintain the operation of the pressure roller, which increases energy consumption. Long-term friction may cause increased wear and shorten the service life. In addition, the ring die granulator cannot screen the quality of the final product, reducing production efficiency.
