    • Systems and methods for conditioning sewage having entrained solids which clog sewage pumps, are disclosed. Systems include a sewage pump, a chopper pump, and a mixing nozzle connected to the chopper pump. Specifically, the sewage pump is a non-clog centrifugal pump having an inlet for drawing fluid into the pump and an outlet for discharging the fluid into a pipe, while the chopper pump has an inlet for drawing fluid into the pump and an outlet for discharging the fluid into the wet-well. The chopper pump may be positioned either in or adjacent to the wet-well. The mixing nozzle fluidly coupled to the chopper pump discharge, is positioned in the wet-well. Methods include the steps of positioning a chopper pump within the wet-well, drawing in liquid sewage, including the entrained solids, reducing the size of entrained solids, and discharging the sewage and reduced size solids into the wet-well.
    • 公开了用于调节堵塞污水泵的夹带固体污水的系统和方法。 系统包括污水泵,斩波泵和连接到斩波泵的混合喷嘴。 具体地,污水泵是具有用于将流体引入泵的入口和用于将流体排放到管中的出口的非堵塞离心泵,而斩波泵具有用于将流体引入泵的入口和用于排出的出口 流体进入湿井。 斩波泵可以位于或靠近湿井。 流体耦合到斩波泵排出口的混合喷嘴位于湿井中。 方法包括将斩波泵定位在湿井内,抽取液体污水,包括夹带的固体,减少夹带的固体的尺寸,排出污水并将固体减少到湿井中的步骤。

    • In a waste pulping apparatus, an impeller assembly comprises a rotating blade for pulping solid waste to form a slurry, the rotating blade having an axis of rotation, a base and a plurality of ears that axially extend away from the base. The impeller assembly also includes a sieve ring having axially opposed first and second ends, an inner cylindrical surface and an outer cylindrical surface, where the sieve ring encircles the base of the rotating blade at the first end so that a portion of the ears are radially spaced inside the inner cylindrical surface so that the ears rotate within the sieve ring. A plurality of pumping vanes are also provided for pumping the slurry, where each pumping vane has a pumping surface that rotates radially outside the outer cylindrical surface of the sieve ring. Preferably, the pumping vanes can be easily changed to allow for various head condition while providing a predetermined pumping capacity.
    • 在废纸浆设备中,叶轮组件包括用于制浆固体废物以形成浆料的旋转叶片,旋转叶片具有旋转轴线,基部和多个耳轴,其从基部轴向延伸。 叶轮组件还包括具有轴向相对的第一和第二端,内圆柱形表面和外圆柱形表面的筛环,其中筛环在第一端围绕旋转叶片的基部,使得一部分耳朵径向地 内圆柱表面间隔开,使得耳朵在筛环内旋转。 还提供多个泵送叶片用于泵送浆料,其中每个泵叶片具有径向地在筛环的外圆柱形表面外旋转的泵送表面。 优选地,泵叶片可以容易地改变以允许各种头部条件,同时提供预定的抽吸能力。
