Embodiment Construction

[0015] The specific implementation of the discharge tray of the granulator with cooling structure will be described in detail below in conjunction with the examples and accompanying drawings, but the specific implementation of the present invention is not limited to the following examples.

[0016] Such as figure 1 As shown, the inner and outer circles of discharge holes 2 are evenly designed on the ring-shaped disc body 1, and the inner and outer walls of the ring are respectively an annular inner plate 12 and an annular outer plate 13, which are used to seal the waterway. The knife groove processed has formed a sealed waterway environment , this design makes the processing of the water channel only need ordinary lathes to process and combine, avoiding the high cost caused by die-casting or metal rapid prototyping. The angles α and β formed by the initial discharge holes of the inner and outer layers in the first quadrant and the horizontal axis are 3~5° and 4~6° respectively...

Abstract

The invention discloses a material discharging tray of a pelletizer with a cooling structure. By a special internal cycle cooling structure designed on the material discharging tray of the pelletizer, high temperature caused by heat generated when compressing the material is effectively reduced, granules are easily formed, simultaneously, heat generated when compressing the material is effectively dissipated, a pelletizing plate and a rotating bearing are in an optimum work state of low heat load, and work time and service life of a system is prolonged. Simultaneously, stepped surfaces arranged in extrusion holes and matched to granule forming hole separating lining made from a wear resistant material, prolongs whole wearing time, and solves problems of bad forming quality, short continuous work time and high maintenance cost, which are caused by temperature rising when a traditional pelletizer continuously works.

Description

technical field [0001] The invention relates to a granulation component of biomass granular fuel applied in the field of new energy production, in particular to a discharge tray structure of a temperature-controllable granulator. Background technique [0002] With the shortage and exhaustion of mineral energy, the use of renewable biomass energy for power generation has attracted widespread attention in the industry. my country is a large agricultural country, especially the annual output of sugarcane, straw and bark in the south is very large, and biomass raw materials are used as fuel. , low cost, clean and pollution-free, is an ideal biomass energy. The use of biomass for power generation requires the raw materials to be crushed and granulated to prepare biofuels suitable for use in boilers. There are several types of granulation core workpieces in the prior art. [0003] 1. A granulation mechanism with a cooling device, the authorized announcement number is CN200947753Y...
