Technical Field

[0001] The utility model relates to the technical field of pellet machines, in particular to a centrifugal device for a vertical ring die high-moisture pellet machine. Background Art

After crushing, pressurizing, densifying and forming, it becomes small stick-shaped solid pellet fuel. Its performance determines the processing output to a large extent and occupies a very important position in the fuel processing process. It can replace firewood, raw coal, fuel oil, liquefied gas, etc. It is widely used in heating, domestic stoves, hot water boilers, industrial boilers, biomass power plants, etc. Before the vertical ring die pellet machine performs pelleting, a centrifugal device is needed to be used to centrifugally dehydrate the high-moisture biomass raw materials to ensure the quality of the pelletized products.

[0003] In the process of dehydrating biomass raw materials by the existing device, as the centrifugal force increases, the filter layer in the device will hang on the wall due to the biomass raw materials attached to the surface, which not only leads to poor dehydration effect and low efficiency, but also easily causes the filter holes of the filter layer to be blocked, and the dehydration work cannot be continued. In addition, the existing device has no stirring structure. During the dehydration process, the raw materials can only be dehydrated by centrifugal force. Under the action of centrifugal force, the raw materials are accumulated on the filter layer, and the raw materials cannot be dispersed, resulting in the inability to remove the inner water and low efficiency.

[0012] 1) When the device is used, the biomass raw materials are added from the feeding hopper to the inner periphery of the filtering annular net and the upper side of the chassis, and then the motor is started to drive the electric push rod to rotate, so that the chassis also rotates. At this time, the spiral blade on the outer side of the fixed end of the electric push rod rotates, constantly turning the biomass raw materials and applying centrifugal force to the biomass raw materials, dehydrating the biomass raw materials, and preventing the biomass raw materials from accumulating together due to the centrifugal force. The water in the biomass raw materials is thrown out through the filter holes on the filtering annular net, collected and gathered on the upper side of the inclined guide ring plate, and discharged to the outside of the device through the drain pipe.
