Flexible tube side by side connected high-temperature, high-pressure squeezing and drying solid-liquid processing equipment

Abstract

The invention provides a flexible pipe parallel connection typed high-temperature and high-pressure squeezing and dry solid / liquid processing device; during the squeezing process, the solid / liquid separation is completed by a squeezing principle of changing volume of a filter chamber; the volume of the filter chamber can be near zero after the volume is changed; high pressure pump can not be needed to convey the raw material and additional squeezing water pump systems or squeezing air systems are not required to be taken as the filter pushing force of a press-filter; the mechanical pushing force is large and the pressurizing is quicker; repeated nipping filtration can be adopted; the washing filter slag is dipped; during the squeezing process, the alternative change of the thickness of the raw material improves the filtration speed, the washing speed and the efficiency; the humidity of a filter cake is uniform; the filtration and squeezing can be carried out at the same time when the vacuum or steam drying is carried out; the production quantity of each sequence batch is easily changed according to the requirement of production capability; the washing regeneration of the filter medium is automatically completed; the slag drainage is automatically completed; during the production process, various automatic protections can be adopted, thus completely realizing the automation, reducing the energy dissipation and having high production efficiency.

Description

technical field [0001] The invention relates to a side-by-side high-temperature, high-pressure pressing and drying solid-liquid treatment device with flexible pipes for solid-liquid treatment of viscous and fine-grained substances, especially suitable for papermaking wastewater treatment, sludge treatment, river dredging mud treatment, drilling Solid-liquid separation of mud treatment, wet smelting wastewater treatment, coal washing wastewater treatment, livestock and poultry breeding pollutants disposal and filling mining mud treatment. It is also suitable for pressing, leaching, Requirements such as hot pressing reaction or washing; especially suitable for the production of liquid fuel from raw materials such as biological raw materials, activated sludge and coal; they all need to obtain filter residues with low liquid content on the premise of low energy consumption and high efficiency .

[0002] In the existing flexible tube type solid-liquid treatment device, for example, in "flexible tube filter" application number 200420092669. Type filter" application number 200510063679.X, "flexible tube hot filter type activated sludge solid-liquid treatment device" application number 200610084906.1 and "flexible tube type solid-liquid treatment device" application number 200710048403.1. The slag scraper scheme of the slag piston mechanism and the propeller blade, although these schemes are feasible to remove the filter residue attached to the filter membrane during filtration, the mechanism is still relatively complicated; in many cases, the screw used in the power transmission mechanism or the cable of the multi-strand cable The transmission cost is still relatively high; the flushing mechanism needs to be further optimized; in addition, the means of automatic control and protection of the equipment need to be further clarified
