Description

Technical Field

[0001] This utility model relates to the field of extrusion granulation equipment technology, specifically to an organic fertilizer double-roller extrusion granulator that prevents sticking to the wall. Background Technology

[0002] Organic fertilizer is a carbonaceous material made from organic matter-rich resources such as plant and animal remains and excrement through fermentation and decomposition. Its nutrients are slowly released after microbial decomposition, improving soil structure, enhancing water and fertilizer retention capacity, and regulating soil micro-ecological balance. This can improve the quality of agricultural products and soil productivity. To improve fertilizer utilization and facilitate storage and transportation, organic fertilizer needs to be extruded and granulated, often requiring a double-roller granulator. The double-roller granulator utilizes the principle of double-roller extrusion to compress powdery materials into granules and is widely used in the fertilizer, chemical, feed, and pharmaceutical industries.

[0003] In response, Chinese utility model patent CN216296246U discloses a double-roller extrusion granulator for zinc oxide production. It includes a material box with an extrusion cavity, two extrusion rollers located within the extrusion cavity and rotatable along their own axes, and extrusion grooves on the side walls of the extrusion rollers. Material falling between the side walls of the two extrusion rollers can enter the extrusion grooves. One extrusion roller can rotate in the opposite direction to the other, so that the material entering the extrusion groove is subjected to the extrusion action between the two extrusion rollers to form granules. The double-roller extrusion granulator for zinc oxide production also includes a vibrating working piece and a heating element for heating the working piece. The working piece includes a material cavity capable of carrying material and a material channel communicating with the bottom of the material cavity. The material channel extends into the extrusion cavity and is located above the area where the two extrusion rollers are close together. Material in the material cavity can fall between the two extrusion rollers through the material channel. Using the above structure, this application can effectively reduce zinc oxide powder mixed in with zinc oxide granules.

[0004] During the extrusion granulation process, the extrusion rollers are prone to overheating due to friction, which often leads to material adhesion. To address this issue, we propose an anti-sticking organic fertilizer double-roller extrusion granulator. Utility Model Content

[0032] Example 2:

[0033] Please see Figure 1 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment;

[0034] Specifically, the extrusion assembly 3 includes two extrusion rollers 31. One end of each extrusion roller 31 is symmetrically rotatably connected to the inner wall of the processing box 1.
