Problems solved by technology

However, during the operation, the dry anaerobic fermentation material has a high solid content and high viscosity, and the groove at the end of the blade is easy to adhere to the material, especially the bottom sand
As the amount of material adhered to the end groove increases, the stirring and mixing effect of the groove structure on the material will be greatly reduced, thereby reducing the stability of the reactor operation

Abstract

The invention provides a stirring paddle and a stirring device, and the stirring paddle comprises a stirring paddle rod connected with a paddle end part, wherein the paddle end part comprises a concave part provided with an unsmooth surface and positioned on a first side of the blade end part, and a lug boss provided with a chamfer and positioned on the second side of the paddle end part. According to the stirring paddle and the stirring device, the bionic design is adopted, the concave part with the non-smooth surface and the lug boss with the specific chamfer are arranged at the paddle end part, viscosity reduction and resistance reduction are achieved, and meanwhile the risk that a stirring shaft is broken can be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of environmental protection, more specifically to stirring. Background technique [0002] Dry anaerobic fermentation has the characteristics of strong resistance to impurities, high volume load, high volumetric gas production rate, and low energy consumption, but it also has the disadvantages of long reaction cycle, easy acid inhibition and ammonia nitrogen inhibition. At present, most of the dry anaerobic reactors used in industry are horizontal reactors, and the mixing of materials is the key to the stable operation of the reactors. At present, the reactor generally uses a horizontal stirring device to realize material mixing, and the stirring device is composed of a stirring shaft and a single-blade paddle with equidistant helical distribution. The single-blade paddle is composed of a paddle shaft and a groove at the end of the blade. During the stirring process, the end groove can scoop up the...
