Device for collecting, conveying and performing extrusion dewatering sludge by virtue of flexible pipe

Abstract

The invention provides a device for collecting, conveying and performing extrusion dewatering sludge by virtue of a flexible pipe. The device comprises a frame, a collecting storage bin, a conveyer, a pipeline system, a filtrate discharge system and a control system, wherein the conveyer comprises a flexible pipe filter chamber, a filter chamber opening and closing mechanism and an extrusion mechanism. The device works in two following modes: 1. the collecting storage bin is arranged at the discharge port of a dehydrator, the collected sludge is filled into the flexible pipe filter chamber, the filter chamber opening and closing mechanism is closed, then the filter chamber is clamped by the extrusion mechanism for deep dehydration, and finally the dewatered sludge is extruded into a conveying pipeline so as to be discharged; and 2. slurry is filled into the filter chamber through a pump and then the filter chamber is clamped by the extrusion mechanism for dehydration, the filter chamber opening and closing mechanism is opened after dehydration is finished, and dried mud in the filter chamber is extruded into the collecting storage bin; and after a certain amount of the sludge is stored in the collecting storage bin, the step in the mode 1 is executed when the sludge needs to be conveyed, and the drier raw material is deeply dewatered and then is extruded into the conveying pipeline so as to be discharged. Therefore, by adopting the modes, the device can automatically and circularly complete tasks of dewatering and conveying the material.

Description

technical field [0001] The invention relates to a sludge flexible pipe extrusion dehydration conveying device for the treatment of viscous and fine-grained substances, which is especially suitable for papermaking wastewater treatment, sludge treatment, river dredging mud treatment, wet smelting wastewater treatment, coal washing wastewater treatment and Treatment of pollutants in livestock and poultry breeding industry. Background technique [0002] After being processed by equipment for solid-liquid separation, the existing disclosed viscous and fine particles generally need to be carried into the silo, and then transported to the carrying equipment so as to be placed in a remote place, such as dryers, incinerators, filling In places such as burying houses or fertilization tanks, the equipment for carrying sludge can be screw conveyors, belt conveyors, piston pumps or cars, etc. These equipments have high manufacturing costs, low transmission efficiency, and toxic odors are...
