As further improvement, described backflushing pipe and pulp pipeline are by the public described grout outlet of switching device shifter.
As further improvement, described switching device shifter comprises rotary baffle, is provided with diversion pipeline in the rotary baffle, and the below of rotary baffle is provided with the spill mouth, sidewall is provided with the flow-guiding mouth that separately can connect pulp pipeline and backflushing pipe, and diversion pipeline connects spill mouth and flow-guiding mouth; And above the filter chamber, be provided with projection, and described grout outlet is arranged on the projection, and rotary baffle is mounted on the top of projection by the activity of spill mouth.
As further improvement, be respectively equipped with air bleeding valve on the described pulp pipeline.
The present invention since adopted above-mentioned technical scheme, this filter need not calcine, without dismounting, without preheating, just can realize the filter core on-line cleaning, the impurity more than 95% that adheres on the filter core through the mistake of backwash is removed; Utilize this filter to reduce melt waste discharge amount, reduced secondary pollution, simple, convenient, reach do not calcine, not dismounting, not preheating, quick, save time, laborsaving, purpose that labour intensity is low.

Fig. 2 is the structural representation of rotary baffle.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
The vertical double filter of Direct-spinning of PET Fiber as shown in Figure 1, this filter comprises pulp-inlet pipe 1, advance to starch transfer valve 2, two filters 4, outlet transfer valve 6 and grout outlet 7, described filter 4 comprises filter chamber 12 and crosses filter core 13, crossing filter core 13 is arranged in the filter chamber 12, the lower end of filter chamber 12 is provided with stock inlet, the upper end of filter chamber 12 is provided with grout outlet, pulp-inlet pipe 1 is connected with two pulp-inlet pipe roads 3 after advancing to starch transfer valve 2, article two, pulp-inlet pipe road 3 is connected to respectively the stock inlet of two filter chambers 12, and be provided with the grout outlet that two pulp pipelines 5 are connected to respectively two filter chambers 12, article two, being respectively equipped with 19, two pulp pipelines 5 of air bleeding valve on the pulp pipeline 5 is connected with grout outlet 7 afterwards by described outlet transfer valve 6.Be respectively equipped with sewage draining exit 10 in the bottom of two filter chambers 12, sewage draining exit 10 is provided with the first by-pass valve control 11, be connected with two backflushing pipes 8 on the described grout outlet 7, article two, backflushing pipe 8 is connected to respectively the upper end of filter chamber 12, and is equipped with the second by-pass valve control 9 at two backflushing pipes 8.
As shown in Figure 1 and Figure 2, above-mentioned backflushing pipe 8 passes through the public described grout outlet of switching device shifter with pulp pipeline 5, switching device shifter comprises rotary baffle 15, be provided with diversion pipeline 17 in the rotary baffle 15, the below of rotary baffle 15 is provided with spill mouth 16, sidewall is provided with the flow-guiding mouth 18 that separately can connect pulp pipeline 5 and backflushing pipe 8, and diversion pipeline 17 connects spill mouth 16 and flow-guiding mouth 18; And above filter chamber 12, be provided with projection 14, and described grout outlet is arranged on the projection 14, and rotary baffle 15 is mounted on the top of projection 14 by 16 activities of spill mouth.
