Description
Technical field
The utility model relates to a kind of filter, and particularly a kind of filter core backwash clapboard type filter completely that makes is mainly used in turbid liquid is filtered.
Background technology
At present, in chemical industry or other industrial processes, often need the turbid liquid that produce be filtered, existing filter mostly is iris type, its structure is: comprise the housing that has loam cake, in the housing inboard dividing plate is arranged, the dividing plate top is the clear liquid chamber, the dividing plate below is turbid sap cavity, the clear liquid chamber of dividing plate top is connected with the purified liquor outlet valve respectively, the filter washing water inlet valve, the blow-back valve, atmospheric valve, the turbid sap cavity of dividing plate below is connected with turbid liquid inlet valve respectively, blowoff valve, dirt discharging valve, the a plurality of filter cores that are positioned at turbid sap cavity are installed on dividing plate, and the clear liquid chamber of top is connected by filter core with the turbid sap cavity of below.The turbid liquid that enters in the turbid sap cavity from turbid liquid inlet valve during work enters the clear liquid chamber by filter core, and the clear liquid after the filtration is discharged housing from the purified liquor outlet valve, and filter residue is intercepted at cartridge surface.Along with the carrying out of filtering, filter residue at the filter core outer surface constantly thickens and forms filter cake, filtration resistance constantly increases, the clear liquid flow constantly reduces, close turbid liquid inlet valve and stop to filter when the pressure reduction between turbid sap cavity and the clear liquid chamber reaches when setting value when dropping to the lower limit rated value (or purified liquor outlet flow), filter core is counter to be cleaned to crossing.During anti-the cleaning, need close turbid liquid inlet valve and purified liquor outlet valve earlier, open atmospheric valve and dirt discharging valve, the liquid in the housing is discharged, close atmospheric valve and dirt discharging valve then.Open blowoff valve, in the clear liquid chamber, be blown into gas from the blow-back valve then, gas more after filtration in-core side-blown promptly blow to filter cake laterally attached to the filter core outside, it is come off, gas and filter cake are discharged by blowoff valve.The filter of this structure has following shortcoming: after the part filter cake on the cartridge surface is blown off, when filter core does not have the lip-deep penetrating area in cake district greater than the gas access sectional area, gas begins to pass filter core from no cake district, the gas purging power that causes carrying on the cartridge surface of filter cake zone reduces greatly, the less power of blowing is not enough so that the filter cake at other positions breaks away from cartridge surface, can not remove whole filter cakes completely.In order to remove whole filter cakes, must carry out manually-operated, very trouble wastes time and energy.
Summary of the invention
The purpose of this utility model provide a kind of thorough removal filter cake, not residual, need not manual work make filter core backwash clapboard type filter completely, overcome the deficiencies in the prior art.
Make filter core backwash clapboard type filter completely, comprise housing, in the housing inboard dividing plate is arranged, the clear liquid chamber of dividing plate top is connected with purified liquor outlet valve, blow-back valve, atmospheric valve respectively, the turbid sap cavity of dividing plate below is connected with turbid liquid inlet valve, blowoff valve, dirt discharging valve respectively, the a plurality of filter cores that are positioned at turbid sap cavity are installed on dividing plate, and the clear liquid chamber is connected by filter core with turbid sap cavity; The inboard of described filter core is provided with the core pipe, and the lower end of core pipe is positioned at the inner chamber bottom of filter core, forms the gap between the outside of core pipe and the inwall of filter core, and the core pipe is communicated with the inner chamber of clear liquid chamber and filter core; Below the housing upper spacer, be connected to the balance port valve.
Make filter core backwash clapboard type filter completely, during the blowback operation, open atmospheric valve simultaneously by the turbid liquid of balance port valve discharge housing internal upper part earlier, make turbid liquid liquid level consistent with balance port valve height, filter core below major part is immersed in the turbid liquid, close dirt discharging valve, atmospheric valve, blowoff valve and dirt discharging valve all are in closed condition, in housing, be blown into gas by the blow-back valve, gas is introduced into the clear liquid chamber, enter filter core inner chamber bottom along the core pipe again, gas oppositely passes the cake layer in the filter core layer and the filter core outside under pressure, enter turbid sap cavity, the bubble disturbance liquid of floating upward quickly produces flow-disturbing, the motive force of flow-disturbing forces filter cake to break away from filter core, gas self-balancing mouth valve behind the flow-disturbing drains into outside the housing, last all filter cake impurity can be discharged from blowoff valve, reach the purpose of the filter cake of all having removed the filter core outside completely, not residual, need not to open the artificial operation of thoroughly cleaning filter core of big blind flange, and reduced the equipment operation, change expenses such as pad and maintenance of equipment, removed installation, suppress, a series of links such as leak test, time saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is a filter core structural representation partly shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2: 1 housing, be fixed with dividing plate 2 in housing 1 inboard, dividing plate 2 is divided into two parts up and down with the inner chamber of housing 1, and the top is clear liquid chamber 17, and the below is turbid sap cavity 18.The clear liquid chamber 17 of dividing plate 2 tops is connected with purified liquor outlet valve 8, blow-back valve 11, atmospheric valve 10 respectively, and the turbid sap cavity 18 of dividing plate 2 belows is connected with turbid liquid inlet valve 7, blowoff valve 6, dirt discharging valve 5 respectively; The a plurality of filter cores 4 that are positioned at turbid sap cavity 18 are installed on dividing plate 2, and the clear liquid chamber 17 of top is connected by filter core 4 with the turbid sap cavity 18 of below.Filter core 4 comprises the link 13 of top and the bottom 16 of below, is filtration members 14 between link 13 and bottom 16, is processed with screw thread on the link 13 or fixedlys connected with dividing plate 2 with flange.Be provided with core pipe 15 in the inboard of filter core 4, can be between the upper end of core pipe 15 and the link 13 and be threaded, the lower end of core pipe 15 is positioned at the inner chamber bottom of filter core 4, i.e. the inner chamber bottom of filtration members 14.Form gap 12 between the inwall of the outside of core pipe 15 and filter core 4, core pipe 15 is communicated with the inner chamber of clear liquid chamber 17 and filter core 4; Be positioned on the housing 1 dividing plate 2 below be connected to balance port valve 3, the height of balance port valve 3 is between the top of filter core 4 below the dividing plate 2.
