Flexible tube side-by-side high-speed, high-pressure squeezing and drying solid-liquid treatment device

Abstract

The invention relates to a flexible tube side-by-side series connection high-speed high-pressure pressing and dryness solid-liquid treatment device. In filtration, a traction mechanism is utilized for pulling a piston scraping residue plate so as to remove the filter residue cut off by a filter medium, and a concentrator and a filter are simultaneously replaced; when pressing, the theory of transfiguration and pressing of a filter chamber is utilized for finishing solid-liquid separation, the filter chamber can approach to zero after the capacity is varied, a pressing water pump system or a pressing compressing air system does not need to be equipped additionally as the filter driving force of the pressure filter, mechanical driving force is larger, and pressure is increased quickly; repeated massage filtration can be adopted, filter residue is soaked and washed, when pressing, the alternative change of thickness of the raw material improves the filter speed, washing speed and efficiency; the degree of wetness of the filter cake is even; filtration and pressing can be carried out simultaneously in vacuum or steam dryness; according to demands of production ability, the amount of production of each order can be changed easily; washing and regeneration of filter mediums can be finished automatically; residue slagging can be finished automatically; complete automation during production can be realized, energy consumption is lowered, and the production efficiency is higher.

Description

technical field [0001] The invention relates to a solid-liquid treatment device for solid-liquid treatment of viscous and fine-grained substances. It is especially suitable for papermaking wastewater treatment, sludge treatment, river dredging mud treatment, and drilling mud treatment. , wet smelting wastewater treatment, coal washing wastewater treatment, livestock and poultry breeding pollutants disposal and filling mining mud treatment and other projects of solid-liquid separation, also suitable for pressing, leaching, hot pressing of chemical substances in industries such as traditional Chinese medicine, food and chemical industry Reaction or washing requirements; especially suitable for the production of liquid fuels from biological raw materials, activated sludge, coal and other raw materials; they all need to obtain filter residues with low liquid content on the premise of low energy consumption and high efficiency.

Problems solved by technology

[0002] In the existing flexible tube type solid-liquid treatment device, for example, in "flexible tube filter" application number 200420092669. The reciprocating slag discharge piston mechanism and the slag scraper scheme of the propeller blades adopted by the known technology on the application number 200610084906.1 of the hot filter type activated sludge solid-liquid treatment device, although these schemes are innovative in pressing, they are still Like the diaphragm pressurized plate and frame filter press in the prior art, the filter residue attached to the filter membrane cannot be removed, and the mechanism for unloading the filter residue is still relatively complicated, which affects the further improvement of the filtration and pressing speed
