Abstract

The invention discloses an ultrahigh-pressure deep sewage sludge dehydrating device. According to the device, preliminarily dehydrated sludge with higher water content is sent to a filter-press cavity, a power mechanism drives a double-toggle link mechanism to act on an extrusion plate, the sludge is deeply dehydrated in the filter-press cavity, a compression characteristic curve of the sludge and a motion characteristic curve of the double-toggle link mechanism are matched, at the beginning stage of compression, the sludge can be compressed for larger displacement by the aid of relatively smaller force, the sludge is compressed to be more and more compact along with proceeding of the sludge compression, the void ratio of the sludge is smaller and smaller, then the sludge can move for small displacement with very large force during sludge compression, and the characteristics of the double-toggle link mechanism meet the conditions; the pressure generated by the power mechanism changes correspondingly as required and is increased at the later filter-press period, huge pressure is formed in combination of the amplifying action and self-locking performance of the double-toggle link mechanism, ultrahigh-pressure filter pressing for the sludge can be realized through smaller hydraulic pressure, more water is extruded out, and the sludge with lower water content is obtained.

Description

technical field [0001] The invention relates to the field of sewage sludge treatment, in particular to an ultra-high pressure deep dehydration device for sewage sludge. Background technique [0002] Sludge is the product of sewage treatment. At present, a large amount of sludge produced after sewage treatment needs further treatment. Dehydration is an important part of sludge treatment. The purpose is to remove most of the water in the sludge, so that the solids are highly enriched. Significantly reducing the volume of sludge to save investment, increasing the calorific value of sludge and saving energy are of great significance for sludge reduction and subsequent disposal. Dehydration can generally be divided into mechanical dehydration and drying dehydration. Drying dehydration consumes a large amount of heat to evaporate the water in the sludge to achieve deep dehydration of sludge. Mechanical dehydration is the most effective dehydration method with the least energy cons...
