The specific embodiment
Combine accompanying drawing that the present invention is done further description through embodiment below.
Embodiment 1
As shown in Figure 1; The described cylindrical filter that is used for filtering water of granulator of present embodiment; It mainly comprises the tubular filter core 3 in lid 2 and the cylindrical outer casing 1 on cylindrical outer casing 1, the shell, and cylindrical outer casing 1 is provided with the water inlet 4 and delivery port 5 that highly equates, the top of said tubular filter core 3 is provided with extensible filter cover 6; The upper surface of described tubular filter core 3 is provided with the annulus 8 that a circumference is provided with small opening 7; Cylinder shape inner wall 9 contact matching of this annulus 8 and cylindrical outer casing 1, annulus 8 is provided with a limited block 10, and the inwall 9 of cylindrical outer casing 1 is provided with one and runs through stopper slot 11 supreme end face, that match with limited block 10; On tubular filter core 3, be provided with water inlet pipe 12 level, relative with water inlet 4, the water inlet end of this water inlet pipe 12 is that caliber with the arc surface of water inlet 4 place's inwalls 9 contact matching and water inlet pipe 12 is greater than water inlet 4.
After tubular filter core 3 is put into cylindrical outer casing 1; Annulus 8 makes tubular filter core 3 doing the circumference rotation with cylinder shape inner wall 9 contact matching of cylindrical outer casing 1; And the cooperation of limited block 10, stopper slot 11 can with tubular filter core 3 be limited on the circumference specific a bit on; Make tubular filter core 3 fixing thus, make water inlet pipe 12 and water inlet 4 align, thereby guarantee that liquid to be filtered can get into tubular filter core 3 inner filtrations by effectively.
And from the slit of 9 of water inlet pipe 12 ends and inwalls the liquid to be filtered of " escaping from ", also be the filtration of having passed through this slit, do not influence filter effect basically.
As shown in Figure 2; The described cylindrical filter that is used for filtering water of granulator of present embodiment is on the inwall 9 of different with embodiment 1 is described cylindrical outer casing 1, to be provided with one 12 that match with water inlet pipe, longitudinal section be semicircular base body 13 for the below of water inlet 4.
After tubular filter core 3 was put into cylindrical outer casing 1, base body 13 contacted with water inlet pipe 12, on second circumference, formed sealing, flow through from the slit of 9 of water inlet pipe 12 ends and inwalls thereby can further reduce liquid to be filtered, further guaranteed filter effect.
As shown in Figure 3, the described cylindrical filter that is used for filtering water of granulator of present embodiment, the place ahead of different with embodiment 2 is water inlet 4 in tubular filter core 3 is provided with the linde sieve tray 14 that a upper end tilts to water inlet 4.
Linde sieve tray 14 can disperse the liquid to be filtered that water inlet 4 is come in, and all filter openings can both be played a role in filtering, and prevents the filter opening of frequent filtration owing to bear after the too many filtration duty blockedly, influences filter effect.
As shown in Figure 4, the described cylindrical filter that is used for filtering water of granulator of present embodiment, different with embodiment 3 is the parallel grating 16 on said linde sieve tray 14 comprises frame 15 and vertically is connected frame 15.The spacing of said parallel grating 16 equates with the filter opening aperture of tubular filter core 3.
In existing cylindrical filter, because that piece relative with delivery port 5 is regional nearest from delivery port 5 on the tubular filter core 3, liquid to be filtered is the fastest from this piece zone velocity after filtering; But because this zone faces water inlet 4, the task of filtration is the heaviest; Bearing very big intake pressure again; Large granular impurity is getting lodged under the effect of hydraulic pressure on this regional filter opening easily, and having slowed down water speed, has reduced filter efficiency.
And the described cylindrical filter that is used for filtering water of granulator of present embodiment; Linde sieve tray 14 is at a distance between above-mentioned zone and water inlet 4; Grating can play certain filter effect; Block above-mentioned zone and influence water speed thereby can reduce large granular impurity, after being mingled with more material between the grating, the monoblock sieve plate can play the effect that disperses liquid to be filtered again in addition.
As shown in Figure 5, the described cylindrical filter that is used for filtering water of granulator of present embodiment, 15 minutes three interlayers of different with embodiment 4 is said frame are at a distance from being provided with, and the angle of inclination is identical.
The described cylindrical filter that is used for filtering water of granulator of present embodiment; On the basis that reaches embodiment 4 effects; In case on the grating behind the long-pending full impurity, the gap between three layers of frame 15 can also make liquid to be filtered effectively pass through, and gets into the fastest area filter of water outlet.
