Pressurized belt type deep dehydrator and application method thereof

Abstract

The invention provides a pressurized belt type deep dehydrator which comprises a main body frame and a filter belt, wherein the main body frame is internally provided with a feeding module, a filter pressing module and a discharging module; the feeding module comprises a uniform distribution mechanism, the uniform distribution mechanism is arranged above the filter belt, and a feeding opening is formed in the upper portion of the uniform distribution mechanism; the filter pressing module comprises a supporting roller and a squeezing mechanism, and the filter belt is wound on the supporting roller and the squeezing mechanism; the discharging module comprises a discharging device and a flushing mechanism; the working surface of the washing mechanism covers the filter belt; and the main body frame is internally provided with a plurality of sets of tensioning mechanisms, and the tensioning mechanisms have various different tensioning pressures including low, medium, high and ultrahigh tensioning pressure. According to the properties of different materials, the acting force on the materials is changed by adjusting the tensioning pressure of the filter belt, and solid-phase and liquid-phase separation of the materials is achieved. The pressure adjusting range is wide, low energy consumption and high energy efficiency are truly achieved, the pretreatment process is combined with various solid waste treatment technologies, the solid waste treatment problem is solved, and the ecological environment is improved.

Description

technical field [0001] The invention relates to a deep dehydrator, in particular to a pressurized belt-type deep dehydrator. Background technique [0002] With the rapid development of my country's social economy, a large amount of solid wastes have also emerged, some of which (such as medicinal residues, sludge with large specific resistance, livestock and poultry manure, etc.) Strong, good pressure resistance, which brings certain troubles to terminal disposal, some will not only cause water, soil and air pollution, but even spread diseases through water, air, biological and other media. [0003] The dehydration treatment of this kind of solid waste is an important part of its terminal disposal and sustainable resource utilization. Because this kind of solid waste has strong solid-liquid binding force and pressure resistance, even high-pressure belt-type deep dehydration The dehydration machine still cannot meet the requirements of terminal disposal for its moisture conten...

Problems solved by technology

[0003] The dehydration treatment of this kind of solid waste is an important part of its terminal disposal and sustainable resource utilization. Because this kind of solid waste has strong solid-liquid binding force and pressure resistance, even high-pressure belt-type deep dehydration The dehydration machine still cannot meet the requirements of terminal disposal on its moisture content, and can only achieve the dehydration effect by using external energy drying method, but the drying has the defects of high investment cost, high energy consumption and high operating cost
