Stalk pellet flat die forming device

Abstract

The invention discloses a stalk pellet flat die forming device which comprises a feed room, a forming die, a rotating shaft, a transmission bar and a press roll, wherein the forming die is arranged at the bottom of the feed room; the rotating shaft penetrates through the forming die and is driven by a power mechanism; the transmission bar extends radially outwardly from the rotating shaft along the feed room; the press roll is rotatably connected to the transmission bar; a forming hole is formed in the circumference, where the press roll revolves along with the rotating shaft, of the forming die; a concentric arc-shaped slot is also formed in the circumference, where the press roll revolves along with the rotating shaft, of the forming die; the forming hole is located in the arc-shaped slot; the diameter of the forming hole is smaller than the width of the notch of the arc-shaped slot; the side part, in contact with the forming die, of the press roll is a convex cambered surface; the length of the side part is smaller than the diameter of the forming hole. The stalk pellet flat die forming device disclosed by the invention is low in comprehensive energy consumption; the power consumption is no more than 40 kilowatts per ton.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a straw granule flat die molding device. Background technique [0002] Fossil fuels such as oil, natural gas, and coal have always been the main energy consumed by human beings. As they are non-renewable resources, they are facing the danger of gradual depletion, so they are not ideal resources that human beings can rely on for a long time. Biomass such as corn straw, wheat straw, rice straw, rice husk, and cotton straw is a kind of renewable high-carbon material. According to incomplete statistics, the annual output of agricultural straw in my country reaches more than 700 million tons, equivalent to nearly 400 million tons of standard coal. . [0003] Straw is a high-quality, environment-friendly fuel, and various chemical products such as combustible gas, activated carbon, soil improver, slow-release fertilizer, foliar fertilizer, and green pesticides can be obtained through resource ...
