Problems solved by technology
The forming die 15 is positioned on the cantilever shaft 18, and the cantilever shaft 18 is bound to be bent and deformed under the greater extrusion force, which changes the row size with the roll 16; reason
Moreover, due to the deformation of the cantilever shaft 18, the raw material particles are unevenly formed, and there are many residual powders. The forming rate can only reach 50%, and the product quality is difficult to be guaranteed.
[0004] In addition, the bearings of the roll 16 are installed in the cavity of the molding die, causing problems such as overheating, overloading, and poor lubrication of the bearings and positioning components in a very short period of time; resulting in a significant decline in the service life of the bearings and positioning components, usually within 24 hours will be damaged

Embodiment Construction
[0018] The present invention comprises a housing 2, and a forming die 4 is arranged in the housing 2 through a rotating bearing 3, and is characterized in that: a roll shaft 6 is arranged in the forming die 4, and the two ends of the roll shaft 6 protrude from the two ends of the housing 2 , and is arranged on the support bearing 11 outside the shell 2; the middle part of the roller shaft 6 is provided with a roller 5 which is in contact with the inner surface of the forming die 4 .
[0019] As a preferred solution of the present invention, two or more roll shafts 6 are arranged in the forming die 4, rolls 5 are arranged on the roll shafts 6, and both ends of the roll shafts 6 protrude from the housing 2. It is also connected to the support bearing 11 outside the housing 2; the roll shaft 6 is evenly distributed on the inner circumference of the molding die 4, and keeps the left and right sides of the molding die 4 balanced.
[0020] Both ends of the housing 2 are provided wit...

The invention belongs to the technical field of granulators, particularly relates to a parallel type double-support granulator, and provides a parallel type double-support granulator with long service life and high granule formation rate. The parallel type double-support granulator comprises a casing, and a forming mold is arranged in the casing through rotating bearings. The parallel type double-support granulator is characterized in that roll shafts are arranged in the forming mold, two ends of each roll shaft extend out of two ends of the casing and arranged on support bearings outside the casing, and a roll contacted with the inner surface of the forming mold is arranged in the middle of each roll shaft.
Description
technical field [0001] The invention belongs to the technical field of granulators, in particular to a parallel double-support granulator. Background technique [0002] my country has a vast territory, and the annual renewable biomass energy (crop straw, grain and fruit husk, forest branches, wood and bamboo sawdust, and wild grass in the mountains) is extremely rich. (Large quantity, many varieties, recycled), However, the amount of biomass clean fuel (particles) converted into alternative coal and fuel oil is extremely limited. The market that can replace coal and fuel oil is huge, and quality raw materials (raw materials for production) are extremely abundant, but such a huge industrial production chain has not yet been formed. The reason is that the technical equipment for producing clean biomass fuels- - Caused by a serious defect in the granulator. [0003] The existing granulator, no matter it is vertical or horizontal, its structure is as follows image 3 As shown, ...
