Problems solved by technology
When this kind of granulator is in use, the friction force generated in the granulation device is relatively large, which requires a large power drive; the friction generates a large amount of heat energy, which makes the temperature of the granulator itself high, and the lubrication and cooling requirements of the moving parts are relatively high. Therefore, there is also a high cooling requirement for lubricating oil; only two pressure rollers are installed, and the working efficiency of the granulator needs to be further improved; Part of the material enters the wedge-shaped extrusion chamber, which is inconvenient to use

Embodiment Construction
[0049] Below in conjunction with accompanying drawing, this technology is further described:
[0050] see figure 1 , figure 2 The ring die granulator shown consists of a frame 1, a granulation mechanism 2 arranged on the frame 1, a feeding mechanism 3 that feeds the granulation mechanism 2, and a lubrication system that provides lubrication for the ring die granulator 4. The main motor 5 that provides power for the ring die granulator is composed of a main shaft 6 that is vertically placed and rotated on the frame 1. The upper end of the main shaft 6 extends into the ring die 202 in the granulation mechanism 2, and a granulation hole 212 is opened on the ring die 202 along the radial direction of the ring die 202; the main part of the frame 1 is the box body 101, and the granulation mechanism 2 It includes at least four sets of pressure rollers 205, the feeding mechanism 3 is a centrifugal feeding mechanism, and the lubrication system 4 includes at least an oil tank 420 tha...

The invention provides a granulator which is reliable and effective in lubrication, capable of forming centrifugal feeding and capable of preventing materials from being accumulated on a pressure roller rack. The granulator comprises a stander, a granulating mechanism, a feeding mechanism, a power source and a lubricating system; the granulating mechanism comprises a main shaft, a pressure roller seat which is connected with the main shaft, a pressure roller shaft which is fixed on the pressure roller seat, a pressure roller which is arranged on the pressure roller shaft in a rotating manner and a circular mold which is fixed on the stander; a main body part of the stander is a box body which is provided with lubricating oil inside and can be used as an oil tank, the power source drives the main shaft to rotate through a gear transmission mechanism in the oil tank, the lubricating system at least comprises an oil pump and an oil path which is used for transmitting the lubricating oil in the oil tank to a rotation pair between the pressure roller and the pressure roller shaft; the feeding mechanism comprises a curved scraper plate which is arranged on the rotating pressure roller seat, and the bending direction of the scraper plate is opposite to the rotation direction of the pressure roller seat.
Description
technical field [0001] This technology relates to a granulator, which can be used for feed granulation, biomass such as straw granulation, etc. It is a granulator that extrudes materials and cuts the extruded rods to make granules. Background technique [0002] The current granulation methods of the granulator include screw extrusion, piston stamping, ring die extrusion and rolling. The typical equipment is a granulator that adopts the ring die extrusion granulation method. The structure of this granulator is that two pressing rollers are arranged in the ring die. When working, a wedge-shaped extrusion chamber is formed between the ring die and the pressing rollers. (part), through the relative rotation of the ring die and the pressure roller, the material in the wedge-shaped extrusion chamber is forced out of the inner ring die by a strong force to complete the granulation. When this kind of granulator is in use, the friction force generated in the granulation device is re...
