The device and its application of using sewage to pretreat straw bales before fermentation

Abstract

The invention discloses a device for pretreatment of baled straw before fermentation by using sewage and an application thereof. The device includes a sewage recovery pool and a feeding pool; one end of the feeding pool is provided with a soaking tank; a pair of dredging wheels are arranged at the intersection of the soaking tank and the feeding pool; the soaking tank is provided with a rotating press wheel and rolling shafts arrayed equidistantly in order, the tail end of the soaking tank is provided with an inclined slope gently rising, the width of the soaking tank is more than that of the baled straw, and the depth of the soaking tank is more than the height of the baled straw; the horizontal planes of the feeding pool and the soaking tank are constant and are located at a control line close to the lower edge of the rolling shafts in the soaking tank; a drain port is located on the inclined slope at the tail end of the soaking tank; the water level of the sewage recovery pool is lower than that of the feeding pool, and sewage of the sewage recovery pool is lifted to the feeding pool through a pump. The device provided by the invention can completely soak the baled straw, can adjust the displacement speed of the baled straw in the soaking tank, and meets the requirement on the soaking time in the pretreatment process.

Description

technical field [0001] The present invention relates to a device for pretreatment of straw bales before fermentation, in particular to a device for pretreatment of straw bales before fermentation by using sewage and its application. Sewage creates conditions for post-composting in the later stage, and belongs to a kind of agricultural special machinery and equipment and its application. Background technique [0002] With the development of rural economy and agricultural intensification, straw has become another major source of waste in rural areas. The annual "straw burning" problem plagues many parts of China. A large amount of wheat, corn and other stalks are burned in the field, which produces a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit that affects the urban environment. Straw burning is not because there are too many straws, but because they are not fully utilized. According to rele...
