Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of granulator, specifically relates to a novel granulator of double -layer discharge. BACKGROUND

[0002] The granulator is the device that granulates the powder material through extrusion, and is applied in the feed industry and fertilizer industry fields. At present, the ring die pressure roller granulator and the flat die pressure roller granulator commonly used at home and abroad are two kinds of pressure roller type granulating equipment in the feed industry and fertilizer industry production, but in actual production, due to the different raw materials and formula of each industry, the use effect is quite different. The traditional ring die granulator is driven by a rotating ring die to drive the driven pressure roller in the ring die chamber, and the material in the chamber is extruded from the die hole on the inner circle of the ring die to form a pellet, and the granulation is realized. The prior art usually adopts single-layer discharge, and the discharge efficiency is low.

[0003] The patent with the patent publication number CN215312182U and the patent name of a planetary gear isometric extrusion gear type granulator is retrieved, and a planetary gear isometric extrusion gear type granulator is specifically disclosed, which comprises a ring die and a pressure roller. The ring die comprises a ring die body, the ring die body is in a cylindrical structure, and an inner tooth is arranged on the inner side wall of the ring die body. The whole ring die structure is an internal gear structure, that is, there is an internal tooth in a ring body. A die hole is formed in the radial direction of the ring die. The die hole is densely arranged on the outer periphery of the ring die and has the same function as the die hole in the prior art, which is used for extruding material. The pressure roller comprises a pressure roller body, the pressure roller body is in a cylindrical structure, an external tooth matched with the internal tooth is fixedly arranged on the outer periphery of the pressure roller body, and the pressure roller is engaged with the ring die. When the pressure roller and the ring die are engaged and relatively rotated, the material in the inner cavity of the ring die is extruded into the internal tooth and the external tooth. Since the die hole is formed in the radial direction of the ring die, the material is extruded from the die hole through the action of the internal tooth and the external tooth. Gear engagement is linear contact, the contact area is small, and the friction generated is small, so unnecessary friction loss can be reduced. In addition, the amount of material in the gear slot is relatively stable, and the phenomenon of excessive material does not occur. At the same time, the compression is quantitative compression each time, the compression ratio of the product is stable, the hardness of the product is uniform, the quality of the product is stable, the motor load and the equipment operation are stable, so that the loss caused by excessive pressure and heating is avoided. At the same time, the granulator is a quantitative forced compression extrusion granulator, the requirement for the material is low, and the granulation adaptability is wide.

[0004] Through the analysis of the above-mentioned disclosed materials, the effect of the granulator can be realized, but single-layer discharge is adopted, and the working efficiency is not high. UTILITY MODEL CONTENTS
