Straw briquetting machine

Abstract

The invention provides a straw briquetting machine. According to the technical scheme, the straw briquetting machine comprises a base and a stock bin; a motor and a transmission shaft are arranged inside the base, and the top end of the stock bin is provided with a feed port. The straw briquetting machine is characterized in that a disc is arranged between the stock bin and the base, discharge ports are evenly distributed in the side face of the disc, a discharge slide way is arranged on the outer side of the disc, the top of the discharge slide way and the disc are located on the same level, the bottom of the discharge slide way extends to the base, the width of the discharge slide way is gradually reduced from the top to the bottom, more than two extrusion plates are arranged inside the stock bin, the top end of any extrusion plate is provided with cylindrical protrusions which are connected through a connecting shaft, and the connecting shaft is connected with the transmission shaft. The straw briquetting machine has the advantages that impurities in a product are effectively reduced through the rectangular discharge port in the straw briquetting machine, the impurities are not extruded out easily, the briquetting effect is better through the two extrusion plates, and raw materials are more effectively and fully utilized.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a straw briquetting machine. Background technique [0002] Straw fuel is made of solid waste such as corn stalks, wheat straw, straw, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark, etc. Densify and shape to become small rod-shaped solid particle fuel. Pellet fuel is made by extruding sawdust, straw and other raw materials with pressing rollers and ring dies at room temperature. The density of the raw material is generally about 130kg / m3, and the density of the formed particles is greater than 1100kg / m3, which is very convenient for transportation and storage, and at the same time, its combustion performance is greatly improved. [0003] In the prior art, the production of straw fuel is inseparable from the straw briquetting machine. Generally, the straw briquetting machine produces a large amount of straw residues that hav...

Problems solved by technology

[0003] In the prior art, the production of straw fuel is inseparable from the straw briquetting machine. In addition to the required blocky straw fuel, the straw briquetting machine usually produces a large amount of straw residues that have not been completely pressed, which makes the follow-up impossible. Do not add another cleaning and screening process, which increases labor costs and reduces work efficiency, which is not in the interests of the enterprise
