Problems solved by technology

The relatively primitive treatment device is to add calcium powder to the worm conveyor, and the material mainly only passes through the pushing process, so the calcium powder is consumed more, the mixing is uneven, the effect is poor, and it is difficult to improve the sludge properties

Abstract

The invention relates to equipment for high-efficiency premixing reaction of sludge and lime, which comprises a screw sludge feeder. The upper part of the screw sludge feeder is provided with a sludge feeding port, one side of the screw sludge feeder is provided with a first variable frequency motor, the lower part of one side of the screw sludge feeder is provided with an extrusion template, a premixing bin is arranged under the extrusion template, the body of the premixing bin is provided with a matching nozzle, a screw lime feeder is arranged outside the screw sludge feeder, the upper part of the screw lime feeder is provided with a lime feeding port, one side of the screw lime feeder is provided with a second variable frequency motor, the left side of the lower part of the screw lime feeder is provided with a lime discharging pipe, and a compressed air blowing pipe is arranged in the lime discharging pipe. When the equipment operates, a main sludge motor drives the screw sludge feeder to move, a main lime motor drives the screw lime feeder to move, the sludge enters the premixing bin through the extrusion template, and the lime is blown into the nozzle through the discharging pipe and is mixed with the sludge in the premixing bin, thereby realizing the high-efficiency premixing of the sludge and the lime and improving the mixing effect.
