Background

Basket filter, the alternative name: the cylinder type filter or barrel type filter is a common filtering device for liquid filtration, when liquid enters a filter basket through a main pipe, solid impurity particles are blocked in the filter basket, and clean fluid passes through the filter basket and is discharged from a filter outlet. When the filter cartridge needs to be cleaned, the screw plug at the bottom of the main pipe is unscrewed, fluid is drained, the detachable filter cartridge is taken out, and the filter cartridge is installed again after being cleaned. Because the cover is detached for cleaning, time and labor are wasted, the filter free of cover opening for cleaning is invented in the prior art, but the conventional liquid filtering and back blowing device has a common defect, back blowing cleaning gas directly carries out back blowing cleaning on the filter basket, the gas can get away from a shortcut with small resistance during back blowing, the gas often passes through local pores of a filter cake and cannot completely blow down the whole filter cake, and the back blowing cleaning is not thorough.

Example 1

As shown in fig. 1, a basket filter without opening cover for cleaning comprises a partition board 1, a central pipe 2, a filter element 3, a shell 4 and a gas-liquid separator 5, wherein:

casing 4 comprises upper and lower two parts, goes up the casing and passes through flange joint with lower casing, goes up the casing top and is provided with blowback gas import D and clean liquid discharge port B, and the casing bottom sets up turbid liquid import A down, connects the discharge pipe way under the casing bottom down, sets up clean liquid discharge port B and drain E respectively, sets up drain C on the casing 4, and drain C connects vapour and liquid separator 5, and vapour and liquid separator 5 top sets up gas vent F, and the drain E is connected to vapour and liquid separator 5 bottom.

The partition board 1 is fixedly arranged in the shell 4 and fixed between flanges of the upper shell and the lower shell, an internal threaded hole is formed in the center of the partition board 1, external threads are correspondingly arranged on the upper part of the outer wall of a central tube 2 of a cylindrical structure with a through upper opening and a through lower opening, and the central tube 2 is in threaded connection with the partition board 1;

filter core 3 is bottom closed open-ended basket structure in top, arranges casing 4 in, and on filter core 3 top was fixed in baffle 1, filter core 3 was arranged in to center tube 2, and the clearance is left with filter core 3 inner wall to the outer wall of center tube 2.

Use of coarse methanol filtration as an example, the utility model has the following working process:

during operation, crude methanol turbid liquid enters the shell 1 through the liquid inlet A, gas in the shell 1 is discharged through the vent, the gas is discharged through the top exhaust port through the gas-liquid separator 5, and liquid in the gas-liquid separator 5 is discharged through the drain outlet of which the bottom is connected to the slag discharge pipeline; after the gaseous evacuation in the casing 1, thick methyl alcohol turbid liquid carries out filtration purification from 3 outer wall flow direction inner walls of filter core, the clear solution after the purification flows to 1 upper portion of casing through the uncovered flow in filter core 3 top, discharge from clean liquid discharge port B at last, filthy thing granule such as filterable dust adheres to the outer wall formation filter cake at filter core 3, when filter core 3 reaches and sets for pressure differential, the filter starts the blowback cleaning procedure, blowback steam gets into center tube 2 in the filter core 3 from the blowback gas entry D on 1 top of casing, and from 2 bottom openings of center tube flow direction center tube 2 outer walls of center tube and 3 inner wall clearances of filter core, the filter cake of production vortex excitation makes the filter cake of filter core 3 surface peel off, the filter cake after peeling off is discharged from drain E along with turbid liquid. When the filter is stopped, the purified clear liquid in the casing needs to be completely discharged, and the purified clear liquid is selectively discharged from a clear liquid discharge port B at the bottom of the casing 1.

The filter element 3 of the utility model is cleaned without opening the filter, thereby saving time and labor; blowback steam carries out the blowback through center tube 2 and washs filter core 3, and blowback steam produces the vortex exciting force through center tube 2 and makes the filter cake on filter core 3 surface peel off thoroughly, takes off the filter cake effectual, and the filter of filter core is washd with blowback directly to current, has saved the blowback gas, has reduced the blowback time, very big promotion filter work efficiency and life.
