Movable biomass compact molding apparatus and molding roll

Abstract

The invention discloses a movable biomass compaction molding apparatus, which has a frame. A grinding device and a molding device are fixed on the frame; an outlet of the grinding device is arranged above a feed port of the molding apparatus; the molding device is a double-roller type molding device which comprises a pair of concave-convex rollers which can rotate, have adjustable interval and are fixed on the frame; the circumference surface of each roller is provided with a concave die part and a convex die part; radial molding holes are arranged on the concave die parts of the rollers; the axis of each roller is provided with an axial through hole along the axial direction; and the radial molding holes are communicated with the axial through hole. The movable biomass compaction molding apparatus provided by the invention adopts cold molding technology and one-step compaction molding, and does not need drying, heating or cooling, thereby having the advantages of low energy consumption, high efficiency and low cost. Biomass raw materials can be processed in production place and are convenient to use. The molding apparatus adapts the power input design for electric and diesel engines, so as to suit the areas which are scattered in land parcel and short or electrical power, fully utilize resources and benefit vast farmers.

Description

technical field [0001] The invention belongs to the technical field of biomass densification molding processing, and relates to a movable biomass densification molding equipment, and also relates to a molding pressure roller in the equipment. Background technique [0002] At present, the widely used biomass compacting process is to transport the biomass raw materials to a special processing plant. The reason is that the mobility of the existing molding equipment is poor; the biomass is mainly crop straw, firewood and other crops, plants , to transport such loose biomass raw materials scattered everywhere to the processing plant over a long distance requires expensive collection, transportation and storage costs; after processing and molding, the product must be shipped out to the user, and sometimes it is returned to the production provider. The original user of the material raw material. Such centralized processing has caused trouble and waste of secondary handling. Some ...

AI Technical Summary

Problems solved by technology

The energy consumption of drying, heating, extrusion and cooling is very high. In general, the power consumption of each ton of biomass compact molding products is higher than 100 kWh, and some even reach 200 kWh per ton. ; Moreover, the working environment of the screw extrusion is harsh and the life is very short. The life of the screw is usually only a few hundred hours, or even less than 100 hours

Each equipment in the molding machine is placed on a bottom plate with casters, which solves the defects of fixed-point processing and difficult movement, but still needs to heat the raw materials, so it still does not get rid of the disadvantage of high energy consumption, although the The various equipment used in the process can be easily moved, but its high energy consumption and electricity consumption as well as its very heavy weight still restrict its ability to go to various places, especially remote places where electricity is lacking, to process biomass. use; moreover, the working parts at high temperature have poor working conditions and short service life

[0012] The Chinese patent No. 03118876.1 discloses a "complete set of equipment for the production of feed and fuel crop straw molding", which includes dehydration and drying equipment for raw materials, and requires a pre-pressing device. Therefore, it still does not get rid of the large investment and high energy consumption. , the disadvantage of poor mobility

[0013] The application number is 200610017153.2 and the name is "A Biomass Straw Forming Machine". Although the moisture content of the biomass raw material is relaxed and there is no drying device, it still needs to be heated when forming, and the thermoforming technology is used, which still does not get rid of energy consumption. high disadvantage
