Roller die squeezing type granulator

Abstract

The invention discloses a roller die extrusion type granulating machine. The granulating machine comprises a machine frame, a feed device arranged on the top of a machine body, a granulating device arranged below the material charging device, a power driving device arranged at one end of the granulating device and connected with the granulating device and a cooling device and a temperature control device which are arranged on both sides of the granulating machine respectively; roller dies of the granulating device adopt a through-shaft structure or fundamentally changing a cantilevered structure of the roller dies; the power driving device adopts a direct shifting mode of a belt wheel so as to simplify the structure; the granulating device is connected with the power driving device through a telescopic fork universal joint so as to be convenient to assemble and adjust the two roller dies; the air cooled type cooling device is adopted and the temperature control device is added, so that the internal temperature when the granulating device runs can be controlled in the necessary range; the distribution of radial through holes on the outer surfaces of the two roller dies is redesigned; and in assembly, along the axial direction of the two roller dies, the parts without holes on the outer surfaces, relative to the parts with radial through holes, are not changed due to the change of the relatively axial position and the adjustment and elimination of the gap due to abrasion of the two roller dies.

Description

technical field [0001] The invention relates to a granulation device for biomass fuel, feed, solid fertilizer, etc., in particular to a roller die extrusion granulator. Background technique [0002] Chinese Utility Model Patent Application Publication CIV2078650 discloses a "double-roller extrusion granulator" for compound fertilizers and feed. It includes a feeding and discharging mechanism, a driving mechanism, a material making mechanism and a cooling and sealing device; A handle is installed at one end of the rod, and the swing rod is driven by the manual swing handle to swing in the feeding hopper, so as to eliminate the scaffolding of the materials in the hopper and achieve the purpose of material uniformity. Disadvantages: The effect of manual equalization is not good. The drive mechanism includes an electric motor, a reducer, a transmission box, etc.; two transmission shafts are installed in parallel on the upper and lower layers of the transmission box, wherein on...

Problems solved by technology

Disadvantages: the effect of manual operation is not good

Disadvantages: The structure is complicated and the cost is high. When the transmission shaft is moved forward in parallel, the two gears meshing with each other will be staggered, and the wear speed will be increased during operation, thereby reducing the service life of the gears.

Disadvantage: cumbersome operation when installing or eliminating the gap between the rollers

Disadvantages: Artificially use the sealing lining to set up a heat insulation layer for the two rollers, which increases the frictional resistance between the sealing lining and the two rollers; the missing material cannot be removed when the two rollers meet, and the cooling temperature range cannot be reached.
