Embodiment 1

[0052] All membrane units 1 of the invention in the present embodiment are arranged side by side between the upper flange chamber 14 and the lower flange chamber 5; membrane unit 1 comprises the following elements of flexibility: tubular filter membrane 12 and tubular grid 21, at least one The long-axis center line of the tubular filter membrane 12 of layer and tubular grid 21 coincides, and is vertical with horizontal line; Form circular slurry chamber 24 in tubular filter membrane 12, tubular grid 21 is set outside tubular filter membrane 12; The upper flange chamber 14 provided on the upper part of the membrane module is provided with a connecting channel 16 and a discharge branch pipe 14c, and the other end of the filter slurry chamber 24 of each membrane unit 1 on the membrane module is aligned with each other and is perpendicular to the discharge through the connecting channel 16. The branch pipe 14c is connected, and the connecting channel 16 of the membrane unit is prov...

Embodiment 2

[0057] In Fig. 4, 5, 6 and 10, embodiment 2 of the membrane assembly of the present invention is shown, and the difference between this embodiment and embodiment 1 is: a tubular sealing membrane 36 is set outside the tubular grid of the membrane unit, and the tubular sealing The membrane 36 covers the tubular frame 21 from the outside, and forms an annular filtrate collection chamber 36b between the tubular sealing membrane 36 and the tubular filter membrane 12. The upper end of the tubular sealing membrane 36 is connected and sealed to the lower end surface 14a of the upper flange chamber 14 The lower end of the branch pipe 13 and the tubular sealing membrane 36 is connected and sealed to the branch pipe 8 on the upper end surface of the lower flange chamber 5, and the annular filtrate collection chamber 36b communicates with the respective horizontal filtrate collection chamber 17.

[0058]The tubular closure membrane 36 is a thin-walled tube that is flexible and leak-free; t...

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. Background technique [0002] In the existing flexib...
