Air-cooled dedusting system of biomass granulator

Abstract

An air-cooled dedusting system of a biomass granulator is used for forming air convection environment in a granulation room (4). The air-cooled dedusting system of the biomass granulator comprises the granulation room (4), of which the lower end is provided with a discharging opening (5); the air-cooled dedusting system of the biomass granulator is characterized in that the granulation room (4) is provided with at least one air opening, the air opening and / or the discharging opening (5) are connected to a blasting device or a drafting device. The inventive air-cooled dedusting system of the biomass granulator utilizes wind-force to produce air flow in the granulation room, can effectively temperature in the granulation room by the air-cooled form, realize cold pressing forming, and simultaneously dedust the fly ash and powder bits produced in the granulation process and recycle the discharged powder, thus saving cost, greatly enhancing service life of the granulator and yield of granulation, which is a significant renovation in the field of granulation.

Description

[0001] The application of this case is to apply for both a utility model patent and an invention patent for this invention on the same day. The name of the invention is the air-cooled dust removal system for biomass granulator. technical field [0002] The invention relates to the field of biomass granulation, in particular to an air-cooled dust removal system for a biomass granulator. Background technique [0003] At present, in the production process of biological pellets, in the granulation chamber of the granulator, the material and the mold generate high pressure and friction, which makes the material and the mold generate high temperature, so that the temperature in the granulation chamber is usually between 150°C and 350°C. , which is a serious hazard to granulation machinery and granulation quality: [0004] 1. The thermal expansion coefficient of the granulation ring die is relatively large, up to about 5 mm. Repeating this many times will easily lead to the rupture...

AI Technical Summary

Problems solved by technology

[0004] 1. The thermal expansion coefficient of the granulation ring die is relatively large, up to about 5 mm. Repeating this many times will easily lead to the rupture of the ring die, which seriously threatens the service life of the ring die;

[0005] 2. The temperature of the ring die is too high, so that the material is easily carbonized in the ring die hole, resulting in blockage of the ring die hole or becoming a dead hole without discharging, and the granulation output is low;

[0006] 3. When the temperature of the granulation chamber is too high, the bearing of the pressure roller will be damaged more, and the butter added to the pressure roller will melt into thin oil and be lost at 120°C. High and melted, the pressure roller cannot be effectively lubricated, and the bearing of the pressure roller will be damaged within 2 hours at the fastest. Even if lubricating oil is injected every hour, the service life of the pressure roller will not exceed 16 hours at most;

[0007] The serious hazards mentioned above are all caused by the high temperature in the granulation room, how to effectively reduce the temperature in the granulation room has become an urgent problem to be solved
