Embodiment
Embodiment one:
As illustrated in fig. 1 and 2, a kind of corrugated paper filter core, comprise center tube 1 and the filter paper that serves as filter medium, filter paper comprises some layers of corrugation filter paper 2 that are centered around outside center tube 1, all axial consistent with center tube 1 of the corrugation direction of every layer of corrugation filter paper 2, between adjacent two layers corrugation filter paper 2, accompany a layer plane filter paper 3, every layer of corrugation filter paper 2 is by being bonded together between its stupefied peak 21 and the plane filter paper 3 adjacent with this layer of corrugation filter paper 2, the corrugation of every layer of corrugation filter paper 2 and be trapped among between the adjacent plane filter paper 3 with it of its periphery and form first passage 4, between the adjacent plane filter paper 3 with it that the corrugation of every layer of corrugation filter paper 2 and enclosing encloses, form second channel 5 therein, first passage 4 is in the sealing of one end place of center tube 1, second channel 5 is in the sealing of the other end place of center tube 1.At one end place of center tube 1, the corrugation of every layer of corrugation filter paper 2 and be trapped among between the adjacent plane filter paper 3 with it of its periphery and be bonded together first passage 4 is sealed by the first adhesive layer 6.At the other end place of center tube 1, between the adjacent plane filter paper 3 with it that the corrugation of every layer of corrugation filter paper 2 and enclosing encloses therein, be bonded together second channel 5 is sealed by the second adhesive layer 7.The stupefied type of corrugation filter paper is U-shaped.One circle filter paper of next-door neighbour's center tube is corrugation filter paper, and a circle filter paper that is positioned at outermost is plane filter paper.Filtering gas from first passage 4 do not seal one end enter, from second channel 5 do not seal one end flow out, or from second channel 5 do not seal one end enter, from first passage 4 do not seal one end flow out.Be wrapped in center tube skeleton for the filter paper filtering, filtrate is along skeleton axial flow, and filter paper uses glue wire bonding between layers, by the filtrate isolation before and after filtering, prevents runner short circuit.Replace corrugated paper with corrugated structure, filter area increases more than 1.5 times, and corrugation deflection is good, plays good supporting effect, can prevent from being close together between layers and affect filter efficiency and working life.
In the present embodiment, also can first passage 4 and the closed end of second channel 5 in same one end of center tube 1.
Embodiment two:
As shown in Figures 3 and 4, filtering paper structure is identical with embodiment one, difference is, in center tube 1, be positioned at one end place and be provided with one-way valve, this end of center tube 1 is for coordinating with the end face 12 of end cover of filter element 11, the end face 12 of end cover of filter element 11 is plane, the sidewall of center tube 1 is the cylindric frame structure being made up of some vertical muscle and some horizontal bars, valve seat 8 and the center tube 1 of one-way valve are structure as a whole, valve seat has valve seat through-hole 9, and on end cover of filter element 11, corresponding valve seat through-hole 9 places are provided with end cover of filter element hole 13.Valve seat 8 is a round platform, and valve seat through-hole 9 is positioned at the center of round platform and runs through the two ends up and down of round platform, chamfering or round-corner transition between the internal face of valve seat through-hole 9 and valve seat 8 bottom end faces.One end of center tube 1 has at least one bulge loop 10, and the central shaft of the central shaft of bulge loop 10 and center tube 1 is on same straight line, and the object that bulge loop 10 is set is to be against on the end face 12 of end cover of filter element 11, to ensure sealing.Compared with traditional filter core, end cover of filter element has removed valve seat boss, and by into a single integrated structure to valve seat and central, tubular, end cover structure is simpler, end cap in the time of heated baking, the phenomenon that does not exist valve seat to be baked, can effectively avoid end cap in heating process, valve seat is out of shape because being subject to toasting, and guarantees the assembly quality of valve seat and spool, thereby ensures the filtering effect of filter core; And more convenient when the assembling of end cover of filter element and other mechanisms.
Embodiment three:
Filter cleaner, its filter core adopts arbitrary described a kind of corrugated paper filter core in embodiment one and embodiment two.
