Integrated rotary low-temperature extrusion pellet making machine

Abstract

The invention discloses an integrated rotary low-temperature extrusion pellet making machine. The integrated low-temperature extrusion pellet making machine comprise a machine frame, wherein the machine frame is provided with a rotary feeding mechanism, a rotary spinning mechanism, a rotary rounding mechanism and a control center; a pore plate is arranged on the outer side of the spinning mechanism; an extruding hole is formed in the pore plate; the rotating direction of the feeding mechanism and the rotating direction of the spinning mechanism are opposite; the pore plate is in a downwards shrinking circular truncated cone shape; the gap between the spinning mechanism and the pore plate is small; the feeding mechanism slits raw materials into a certain amount of parts and then feeds the raw materials to the spinning mechanism, the raw materials fall onto the rounding mechanism after being extruded out of the extruding hole through the spinning mechanism, and the rounding mechanism rounds the raw materials to be in a ball shape. Pellets are made through the integrated extruding structure, intermediate links are avoided, and therefore product pollution is reduced and product quality is improved; meanwhile, the integrated rotary low-temperature extrusion pellet making machine is reasonable in structure, easy to operate, convenient to dismount and mount and high in feeding speed, the raw materials are not overlapped, the temperature rise of the raw materials is slight, the pore diameter of the extruding hole of the pore plate can be made very small, and neither heating nor plate explosion exists in the production process.

Description

technical field [0001] The invention relates to an integrated rotary low-temperature extrusion pelletizing machine. Background technique [0002] At present, the pelletizing process equipment is a single piece of equipment, and it takes a combination of multiple equipment to complete the pelletizing. The equipment currently in use includes screw extruders, vertical extruders, rotary granulators, and spheronizers. During the pelleting process, some auxiliary equipment (silo) is needed for assistance. Multiple equipments complete a process, and there are many intermediate links, increasing pollution sources and degrading product quality. [0003] The disadvantage of the screw extruder is that it takes some time for the raw material to be transported, and then it enters the screw extrusion. During this movement, the raw material will rub against the screw and the barrel, resulting in a very large calorific value of the raw material, which will denature the raw material. Relea...

Multiple equipments complete a process, and there are many intermediate links, increasing pollution sources and reducing product quality

[0003] The disadvantage of the screw extruder is that it takes some time for the raw material to be transported, and then it enters the screw extrusion. During this movement, the raw material will rub against the screw and the barrel, resulting in a very large calorific value of the raw material, which will denature the raw material. Release will lead to problems such as cracking of the orifice plate, low pellet production, and inability to make small apertures (minimum aperture is Φ0.6mm), and its use cost is high, and it is very inconvenient to disassemble and install.

The disadvantages of vertical extruders are inconvenient installation, few monitoring positions, large equipment volume, extrusion orifice plate is in the direction of a cylinder, extruded raw materials are in a superimposed state and are not easy to disperse, poor heat dissipation effect, low output, and poor dissolution effect. The temperature is high, and it also cannot be made with a small aperture (the minimum aperture is Φ0.5mm), the output is also low, and the cost of use is high

The disadvantage of the rotary granulator is that it cannot make a small aperture (the minimum aperture is Φ0.8mm), the temperature is high, and the orifice plate is easy to be damaged.
