Description

The cover of the many bag type filter devices of miscella and tank body syndeton

Technical field

The utility model relates to a kind of environmental protection, chemical industry, grease fine filtering apparatus, relates in particular to cover and the tank body syndeton of the many bag type filter devices of a kind of miscella.

Background technology

Vegetable oil material must use filter plant to filter to obtained miscella after leaching.After filtration, greatly reduce the dregs of rice end content in miscella, improved the effect of miscella evaporation, remarkable for the improvement of crude oil quality and the comprehensive utilization effect of byproduct.Current miscella generally adopts bag filter to filter.

A kind of novel structure of bag filter, volume are little, convenient and flexible operation, energy-conservation, efficient, airtight work, multipurpose filter plant that applicability is strong.Bag filter is a kind of novel filtration system.Filter bag is supported by Metal net basket in bag filter inside, and liquid is flow to by entrance, after filter bag filters, flows out from outlet, and impurity is tackled in filter bag, after replacing filter bag, can continue to use.

Bag type filtering machine is a kind of pressure type filter, mainly contain critical piece compositions such as filtering tank body, filtration barrel cover and fast opening mechanism, stainless steel filter bag reinforcing mat, miscella flows into filter bag by the side inlet tube of filter shell, filter bag itself is that device is in reinforcement basket, the filter bag that Liquid Penetrant is crossed required fineness grade can obtain qualified miscella, and impurity particle is tackled by filter bag.It is very convenient that this machine is changed filter bag, filters substantially without supplies consumption.

Bag filter possess structure rationally, good airproof performance, circulation could be strong, easy and simple to handle etc. many strong points.Especially filter bag side leakage probability is little, can correctly ensure filtering accuracy, and can change quickly filter bag, and running cost is declined.Filter surfaces externally and internally takes mechanical ash propel polish to solve, average, easy cleaning.We know, the filter method that bag filter is taked is that side is entered the method that side goes out, also can take side to enter the method that the end goes out, by ducted pressure, mistake mixing oil body medium is pressed into or suction bag filter staving, the filtration that the liquid medium filtering is filtered the filter bag of blue support via electropolishing punching support, the solid-liquid changing arrives respectively the result that liquid medium is filtered.

Bag filter mainly contains following a few class: single bag type filter, multi-bag type filter, rocking arm bag filter, high accuracy bag filter etc., filter filtering accuracy 1-10 micrometer range.

The basic parameter of bag filter is as follows:

Principle: pressure filtration;

Purposes: liquid filtering;

Pattern: pocket type;

Performance: essence filter;

Applicable object: Separation of Solid and Liquid;

Applicable object character: high hygienic requirements material;

Filtrate type: needle punched non-woven fabrics;

Main material: nonwoven fabric of long fibers.

Bag filter has following advantage:

(1) bag filter, compact conformation, Sizes.Installation and simple, convenient, floor space is less.(2) the filtering accuracy of bag filter is high, is applicable to any fine particle or suspension, and filter area can be from 0.5～200 micron.(3) the processing flow of unit filter area is larger, and filtration resistance is less, and filter efficiency is high.A liquid filtering bag filtration function is equivalent to 5～10 times of filter cores, can greatly reduce costs; Design discharge can meet 1～500m3/h requirement, and cost cost is low.(4) bag filter is of many uses, can be used for coarse filtration, middle filter or essence filter; In the situation that reaching same filter effect, the equipment such as plate frame filter, filter cartridge type filter that relatively rises has that cost of investment is lower, long service life and filtration low cost and other advantages.(5) filtering accuracy is high, and filtration treatment amount is large, has that cost is low, efficiency high.(6) liquid bag filter exempts to clean, and changing liquid filtering bag can complete in 30 seconds, convenient and swift, saving of work and time.(7) liquid pocket type filter specification is complete, has low pressure, side entering type, inputting type, many pocket types, horizontal.
