Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, described a kind of piping filter, including one end closing, another end opening
Filter cylinder 1, Parallel Symmetric is provided with two along the axially arranged guide rail 2 of filter cylinder on the inwall of filter cylinder 1, two guide rails 2 it
Between slide be provided with cross section be in W types filter screen 3, the openend of filter cylinder 1 is provided with mounting flange 4, cut with scissors on mounting flange 4
The blind flange 5 of the opening of filter cylinder 1 can be opened and closed by being connected to, and mutually be fixed by retaining mechanism between blind flange 5 and mounting flange 4, and be worked as
When blind flange 5 and mounting flange 4 are locked and close filter cylinder 1 and be open, filter screen 3 in filter cylinder 1 just by the inside points of filter cylinder 1 every
Into can only be provided with by upper chamber 6 that the filter opening 31 on filter screen 3 is connected and lower chambers 7 on the filter cylinder barrel of upper chamber 6
Water inlet 8, delivery port 9 is provided with the filter cylinder barrel of lower chambers 7；In the present embodiment, the structure of retaining mechanism is：Pacifying
The opening of filter cylinder 1 is provided with first mounting hole of circle 41 on dress flange 4, second mounting hole of circle is provided with blind flange 5
51, the first mounting hole 41 of mounting flange 4 corresponds with the second mounting hole 51 of blind flange 5, in the first peace corresponding to each pair
A full thread stud 10 is equipped with respectively between the dress mounting hole 51 of hole 41 and second, at the both ends of every full thread stud 10 point
A locking nut 11 is not threaded with, when screwing all locking nuts 11, mounting flange 4 can be made to be locked with the phase of blind flange 5
Fasten, above-mentioned locking mechanism structure is simple, and I＆M is convenient；In the present embodiment, it is provided with the outer end of filter screen 3
Diameter is slightly less than the circular limiting plate 12 of filter cylinder internal diameter, and the madial wall that circular limiting plate 12 is moved inward to along guide rail 2 when filter screen 3 supports
When leaning against on the outer face of guide rail 2, the inner end of filter screen 3 is just against on the blind end inwall of filter cylinder 1；In the present embodiment,
Internal handle 13 is provided with the lateral wall of circular limiting plate 12, the size of Internal handle 13 can ensure that when blind flange 5 closes filter cylinder 1
During opening, blind flange 5 can by Internal handle 13 by circular limiting plate 12 inwardly tight against on the outer face of guide rail 2, so as to will filter
Net 3 is fastened in filter cylinder 1；In the present embodiment, outer handle 14 is provided with the lateral wall of blind flange 5；
The operation principle of the present invention is as follows：
During installation, only need to by the water inlet 8 of filter cylinder 1 with circulating-pump outlet pipeline is relative in forced circulation boiler connects, by filter cylinder 1
Delivery port is relative with the water inlet pipe of forced circulation boiler evaporating area to be connect；
In use, the fluid that circulating-pump outlet pipeline flows out from forced circulation boiler first enters the epicoele of filter cylinder 1 from water inlet 8
Room 6, into upper chamber 6 fluid filtered by cross section in the filter screen 3 of W types after the cleaning fluid that is formed enter lower chambers 7, then from
Delivery port 9 is discharged into the water inlet pipe of forced circulation boiler evaporating area；And enter stream of the fluid of upper chamber 6 after being filtered by filter screen 3
Body impurity can continuous residual buildup on filter screen 3；When filter screen 3 need to be cleaned, all locking nuts 11 only need to be screwed off, are then caught
Outer handle 14 opens blind flange 5, then catches Internal handle 13 to extract the filter screen 3 that need to be cleaned from filter cylinder 1 out, treats that filter screen 3 cleans
Reload filter cylinder 1 again afterwards, be then re-closing off blind flange 5 again, and screw all locking nuts 11 again, by blind flange 5 with
Mounting flange 4 is locked again.
It is an advantage of the invention that：（1）It is simple in construction, easy to operate, dismounting cleaning filter screen it is very convenient；（2）Employ horizontal stroke
Section is in the filter screen of W types, and the filter area of filter screen is big, can more effectively filter the impurity in fluid, good filtration effect.
