Upright diluted oil circulation ring mold pellet mill

Abstract

The invention discloses an upright diluted oil circulation ring mold pellet mill and relates to the technical field of biomass fuel pellet preparation. The pellet mill comprises a pellet mill main body, wherein the pellet mill main body comprises a shell; a feeding shell is arranged at the top end of the shell; a pressing chamber is formed inside the shell; a compression part is arranged inside the pressing chamber; a discharge hole is formed in the bottom of the side wall of the shell; the compression part comprises a pressing roller assembly; the pressing roller assembly is connected with apower transmission mechanism; the output end of the power transmission mechanism is used for driving the pressing roller assembly to rotate through a live spindle; a mold is arranged on the outer sideof the pressing roller assembly; the mold is fixedly mounted on the pellet mill main body; the inner side surface of the mold is in fitted tangency to the pressing roller assembly; and the mold is static relative to the pellet mill main body. The invention aims to provide the upright diluted oil circulation ring mold pellet mill, the mold is static, the pressing roller assembly has both rotationand revolution along with the live spindle, the pressing effect can be improved, a discharge disc cutting mode is adopted for external cutting, and a finished product raw material is rotated to the discharge hole along with the discharge disc and is led out.

Description

technical field [0001] The invention relates to the technical field of biomass fuel particle production, in particular to a thin oil circulation vertical ring die pelletizer. Background technique [0002] Renewable biofuels refer to high-density fuel rods or pellets produced by high-intensity extrusion of agricultural and forestry waste such as straw, sawdust, weeds, shrub branches, and even fruit shells and peels. The combustion value of this particle is 4 times higher than the combustion value of the traditional combustion method. It is a high-grade clean energy with a combustion method and calorific value close to coal but basically no pollutant emissions. It is used for urban and rural domestic energy and industrial use. It can provide an environmentally friendly, economical and safe green consumption method. It can use agricultural and crop waste to make new energy fuels. It is a new energy advocated by the country. [0003] The current granular energy compression equi...

AI Technical Summary

Problems solved by technology

[0006] ① Due to the layout of the ring die, the feed inlet of the ring die granulator must be placed on the side, and a thrust device is required to fill the ring die. Even so, it is still difficult for materials with light specific gravity to enter the pressing chamber;

[0007] ②The layout of the ring die causes the pressing chamber to not dissipate heat in time, which reduces the service life of the whole machine;

[0008] ③When the ring die rotates, the material in the pressing chamber is prone to arching, resulting in uneven feeding, which affects the output and compression efficiency; at the same time, the ring die rotates, and the material has no centrifugal force at all, resulting in uneven distribution of the material

[0009] ④The ring die and the pressure roller need to be driven by independent drive motors respectively, which consumes a lot of power and increases the difficulty and cost of manufacturing

[0011] ①The lower part of the transmission is made of a conventional reduction box in the market, which has a low safety factor; the connection part is often broken, and the high-strength impact force causes the gear teeth in the reduction box to be broken;

[0012] ②Discharging method, using ring die as support, peripheral rotary support type scraper, cutting knife is fixed on the outside of scraper and rotates to cut off; replacement of ring die or maintenance must disassemble / install scraper, and the cutter is on the upper part When rotating, it is easy to crush the finished particles;

[0013] ③The lubrication system is divided into gearbox lubrication (thin oil circulation lubrication) and pressure roller lubrication (high temperature grease lubrication); high temperature grease is special grease, and the cost is very high
