Abstract

The invention relates to a blade and a pressure gradient sand settling machine employing the same. The blade comprises a blade body and a connecting assembly, wherein the blade body is a hollow body, and the connecting assembly is connected with the blade body and provided with mounting holes. The pressure gradient sand settling machine comprises a driving mechanism, a fluidizing mechanism, a sand settling mechanism, a sand lifting mechanism and a sand pool body, wherein the driving mechanism is connected with the sand settling mechanism, the fluidizing mechanism is inserted in the sand pool body, the sand lifting mechanism is arranged in the sand pool body, the sand settling mechanism comprises a stirring shaft and the blades, and the blades are fixedly arranged on the stirring shaft. When the pressure gradient sand settling machine is used, the driving device drives the sand settling mechanism to sink sand to the bottom of the sand pool body, the fluidizing mechanism is used for activating the sunk sand in the sand pool body so enable the sand to flow, and then, the sand lifting mechanism is used for leading sand in the sand pool body to enter a sand lifting pipe. Compared with the traditional equipment, the blade provided by the invention is provided with a hollow structure so that the advantages of simple structure, material saving and low cost are achieved; in addition, a standardized gas storage cylinder is skillfully used for forming differential pressure to lift the sand up so that the equipment is prevented from being damaged in a use process.

Description

technical field [0001] The invention relates to the technical field of sewage treatment machinery, in particular to a paddle blade and a differential pressure grit chamber using the same. Background technique [0002] At present, the cyclone grit settling and sand lifting equipment has always been the first choice of most sewage treatment manufacturers in China. However, it was found in the process of use that the existing cyclone grit chamber sand lifting equipment uses sludge pumps to lift sand. Because domestic sludge contains sundries of different sizes and hardness, during the extraction process, the high-speed rotation produces a large impact force, and the sludge pump is extremely easy to be damaged. Usually, the sludge pump is used for less than one hour. Years have to be replaced. Frequent replacement of sludge pumps is almost a negative number for the company's economic benefits. [0003] In addition, the blades currently used in sand lifting equipment are relati...
