Problems solved by technology

[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

Embodiment 2

[0065] The difference between this embodiment and embodiment 1 is:

[0066] 1. A tubular sealing membrane 36 and a second layer of tubular filter membrane 23 are arranged outside the tubular grid of the membrane unit,

[0067] 2. Set a flushing mechanism under the piston scraper plate 31 of the piston scraper assembly,

[0068] 3. The piston slag scraping assembly is set in the membrane assembly 52b of the intermediate flange chamber of the transition section;

[0069] 4. Set up and down two sets of compression power generating transmission mechanisms 74b and matching upper and lower sets of pressure distribution frames 77;

[0070] A tubular sealing membrane 36 is arranged outside the tubular grid of the membrane unit, and a closed tubular framework 21 is formed between the tubular sealing membrane 36 and the tubular filter membrane 12 to form an annular filtrate collection chamber 36b. The upper end of the tubular sealing membrane 36 Connect and seal the branch pipe 8 on t...

Embodiment 3

[0082]The inventive equipment in this embodiment includes a filter element and a pressure assembly, each filter element includes four membrane assemblies 52, and each membrane assembly 52 includes a membrane unit 1, an upper flange chamber 5, and a lower flange chamber 14 and mechanical slag discharge assembly; all the membrane units 1 of the membrane module are arranged side by side between the upper flange chamber 5 and the lower flange chamber 14; The long axis (row axis) of the shape symmetry center of the blue chamber 5 and the lower flange chamber 14 coincides; the long axes (row axis) of the four membrane modules 52 of the filter element are parallel to each other.

[0083] The difference between this embodiment and Embodiment 2 mainly lies in that in this embodiment, a fluid combination channel 41 is arranged on the lower end surface of the upper flange chamber 5 of each membrane unit of the membrane module, and a fluid combination channel 41 is arranged between the raw...

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.
