[utility model content]
The technical problems to be solved in the utility model is to provide a kind of online switching spandex to spin preceding former liquid filter, and it can be implemented in line switches, and avoids the production capacity waste, has guaranteed the quality of spinning solution again.
The utility model is achieved in that
A kind of online switching spandex of the utility model spins preceding former liquid filter, it comprises filter chamber one, filter chamber two, valve one, valve two, valve three, valve four, described filter chamber one, valve one, valve two, filter chamber two, valve four, valve threeway piping connects successively, described valve three is also connected to filter chamber one, pipeline between described filter chamber one and the valve one is connected to a blowoff valve one, described valve one, pipeline between the valve two is connected to the stoste inlet, described valve two, pipeline between the filter chamber two is connected to a blowoff valve two, described filter chamber one, pipeline between the valve three is connected to an air bleeding valve one, described filter chamber two, pipeline between the valve four is connected to an air bleeding valve two, described valve four, pipeline between the valve three is connected to the stoste outlet.
Further, described filter chamber one, filter chamber two are dismountable cylindrical shell.
Advantage of the present utility model is:
The utility model does not need off-position or stops under the situation of line, realize online switching, avoided previous because therefore off-position or stop the production capacity waste that line causes has increased productivity effect, and before originally spinning behind the former liquid filter pressure oscillation scope can be controlled at 5kg/cm
2Scope in, make the supply pressure of booster pump greater than 15kg/cm
2, satisfy technological requirement;
Filter chamber one of the present utility model, filter chamber two adopt dismountable cylindrical shell, can be transported to assemble between cleaning and disassemble, get final product to on-the-spot trap, disassemble the operating efficiency of cleaning thereby improve, reduce relevant workload, the stoste in the cylindrical shell is cleaned out simultaneously, and the stoste of ingress of air is all drained in the time of switching, improve the quality of spinning solution, kept the stability of product quality.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
[specific embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
As Fig. 1, a kind of online switching spandex of the utility model spins preceding former liquid filter, it comprises filter chamber 1, filter chamber 22, valve 1, valve 24, valve 35, valve 46, described filter chamber 1, valve 1, valve 24, filter chamber 22, valve 46, valve 35 connects successively by pipeline, described valve 35 is also connected to filter chamber 1, pipeline between described filter chamber 1 and the valve 1 is connected to a blowoff valve 1, described valve 1, it is booster pump 8 that pipeline between the valve 24 is connected to the stoste inlet, described valve 24, pipeline between the filter chamber 22 is connected to a blowoff valve 29, described filter chamber 1, pipeline between the valve 35 is connected to an air bleeding valve 1, described filter chamber 22, pipeline between the valve 46 is connected to an air bleeding valve 2 11, described valve 46, pipeline between the valve 35 is connected to the stoste outlet.Described filter chamber 1, filter chamber 22 are dismountable cylindrical shell.
Below operation principle of the present utility model is described in detail:
When former liquid filter uses first before originally spinning, use filter chamber 1 to work earlier, spinning solution enters from the stoste inlet, make blowoff valve one 7 standard-sized sheets, valve one 3 standard-sized sheets, slowly start booster pump 8 then, carrying out blowdown releases, when blowoff valve 1 flows out clean stoste, blowoff valve 1 is closed extremely air bleeding valve one 10 standard-sized sheets, carry out exhaust, when the stoste of discharging from air bleeding valve 1 does not have bubble (visual),, begin normal feed flow with valve 35 standard-sized sheets (this moment, valve 24 and valve 46 were in closed condition).Described booster pump 8 carries out PID (proportional integral derivative adjusting) by frequency converter, PIC (pressure controller), PT (pressure transmitter) to be regulated, make originally spin before pressure behind the former liquid filter remain on 20kg/cm
2
Pressure reduction before originally spinning before and after the former liquid filter surpasses 20kg/cm
2The time, filtration work one 1 need be switched to filter chamber 22 from the filter chamber, and then filter chamber's one 1 integral body are moved on to cleaning shop disassemble cleaning.Concrete handover operation process:
1. the operation of releasing: spinning solution enters from the stoste inlet, successively valve 24, valve 46 are slowly opened a bit earlier before switching, the old stoste of leaving over originally that is used for valve 24, valve 46 are connected to filter chamber's 22 interfaces rinses out, visual inspection is up to there not being old stoste to flow out, shut off valve 24, valve 46 again, the EO of releasing.In operation valve 24, valve 46, must slowly open, also will observe the variation of the pressure behind the former liquid filter before spinning simultaneously, avoid pressure oscillation herein excessive.
2. fitting operation: filter chamber's 22 hoisted in position that assemble, with the inlet and outlet connectors position of filter chamber 22 to good tight, installment work is finished.
3. bleeding: earlier with air bleeding valve 2 11 standard-sized sheets, valve 24 is slowly opened a bit, carried out exhaust, when the stoste of discharging from air bleeding valve 2 11 does not have bubble (visual), the gas emptying in the filter chamber 22 is described, shut off valve 24; Valve 46 is slowly opened a bit, when the stoste of discharging from air bleeding valve 2 11 does not have bubble (visual), the gas emptying of valve 46 to the pipeline between the air bleeding valve 2 11 is described.Close air bleeding valve 2 11 and valve 46, bleeding finishes.In operation valve 24, valve 46, must slowly open, to observe also simultaneously that the pressure behind the former liquid filter changes before spinning, avoid the fluctuation of pressure herein excessive.
4. handover operation: valve 24 is slowly opened until standard-sized sheet, then valve 46 is slowly opened until standard-sized sheet, work simultaneously in filter chamber 1, filter chamber 22 at this moment, slowly close until whole passes valve 1 dead again, close valve 35 dead then, this moment, filter chamber 22 worked independently, and so far handover operation is finished.
5. disassembling section: air bleeding valve 1 is opened, filter chamber 1 is carried out pressure release, the import and export of filter chamber 1 are unclamped, hang in the special-purpose go-cart, shifting cleaning shop onto disassembles, so far, the switch operating of former liquid filter is finished before all spinning, and (pressure reduction before spinning before and after the former liquid filter surpasses 20kg/cm if filter chamber's 22 uses expire
2The time), switch to filter chamber 1 with reference to above-mentioned steps.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
