Embodiment
Fig. 1 illustrate is the schematic representation of the filter screen of one embodiment of the invention.Fig. 2 illustrate is the sectional arrangement drawing along I-I ' hatching among Fig. 1.
Please refer to Fig. 1, the outward appearance of filter screen 100 is tapered, can increase the surface area of filter screen 100 effectively.Filter screen 100 comprises bottom 102 and top 104, and filter screen 100 102 104 converges to a bit along straight line to the top from the bottom, can make impurity easily landing to the below, so can avoid filter screen to block comprehensively.Wherein, bottom 102 in the form of a ring, though be in the present embodiment with circular be example as an illustration, be which kind of ring-type for bottom 102, not special restriction.The shape of bottom 102 also can be polygon ring-type except circular, has in this technical field and knows that usually the knowledgeable can adjust voluntarily according to demand.
The material of filter screen 100 for example is materials such as metal or Furtulon.Material that it should be noted that filter screen 100 should be decided on the fluid that will filter, and selected material must have corrosion resistance to the fluid that will filter.
Please refer to Fig. 2, the longitudinal section of filter screen 100 is inverted v-shaped, and has angle Θ at the central axis 106 of filter screen 100 with the conical surface 108, and makes filter screen 100 have a slope, the more little slope of angle Θ is big more, makes the easy more landing of the impurity that will filter to the below and slope is big more.The slope of filter screen 100 for example is more than or equal to 1.
By the foregoing description as can be known, because filter screen 100 has bigger surface area, so and be not easy to be blocked by impurity, and can promote filter efficiency.In addition because filter screen 100 102 104 converges to a bit along straight line to the top from the bottom, can make impurity easily landing blocked by impurity to avoid filter screen 100 to the below comprehensively, therefore can promote filter efficiency significantly.
Fig. 3 illustrate is the schematic representation of the fluid circulating device of one embodiment of the invention.In Fig. 3, the member identical with Fig. 1 and Fig. 2 then uses identical label and omits its explanation.
In addition, fluid circulating device 200 more can comprise driving fit element 208, is arranged at the joint between pipeline 204 and the pump 202, to promote the adaptation of joint.In the present embodiment, driving fit element 208 for example is to be disposed between pipeline 204 and the conversion adapter 206, and between conversion adapter 206 and the pump 202.Driving fit element 208 for example is an O type ring.The material of driving fit element 208 for example is a rubber.
By the foregoing description as can be known, because fluid circulating device 200 employed filter screens 100 are except surface area is big, more can make impurity 212 be slipped to the below easily along the conical surface 108, cause comprehensive obstruction so can prevent 212 pairs of filter screens 100 of impurity, and have preferable FLUID TRANSPORTATION usefulness.Thus, can avoid because of the not good situation that causes process disruption of FLUID TRANSPORTATION efficient, and can promote manufacturing efficiency effectively, and can prevent to cause the problem of product rejection because of process disruption.
In addition, because filter screen 100 has preferable filter efficiency, and can prevent that 212 pairs of pumps 202 of impurity from causing damage, and can save the maintenance and the renewal cost of pump 202.
Fig. 4 illustrate is the schematic representation of the fluid circulating device of another embodiment of the present invention.In Fig. 4, the member identical with Fig. 3 then uses identical label and omits its explanation.
Please be simultaneously with reference to Fig. 3 and Fig. 4, the difference of the fluid circulating device 200 among the fluid circulating device 200 ' among Fig. 4 and Fig. 3 only is: the direction of top 104 indications of filter screen 100 is identical with the flow direction 210 of fluid among Fig. 4, and the direction of top 104 indications of filter screen 100 is opposite with the flow direction 210 of fluid among Fig. 3.
Similarly, in the present embodiment, because fluid circulating device 200 ' the employed filter screen 100 has bigger surface area, and can make impurity 212 be slipped to the below along the conical surface 108 easily, cause comprehensive obstruction so can prevent 212 pairs of filter screens 100 of impurity, and have preferable FLUID TRANSPORTATION usefulness.In addition, because filter screen 100 has preferable filter efficiency, so can save the maintenance and the renewal cost of pump 202.
Fig. 5 illustrate is the schematic representation of the filter screen of another embodiment of the present invention.
Please be simultaneously with reference to Fig. 1 and Fig. 5, the difference of the filter screen 100 among the filter screen 300 among Fig. 5 and Fig. 1 is: the bottom 102 of filter screen 100 in the form of a ring, and the shape of the bottom 302 of filter screen 300 is polygon ring-type, for example is five side ring shapes among Fig. 5.The material of the filter screen 300 of Fig. 5 and the filter screen 100 of effect and Fig. 1 are roughly the same, so repeat no more in this.
In the same manner, because filter screen 300 has bigger surface area, therefore can promote filter efficiency effectively.In addition because filter screen 300 302 304 converges to a bit along straight line to the top from the bottom, can make impurity easily landing therefore can get filter efficiency and promote significantly to the below.
In sum, the foregoing description has following advantage at least:
1. filter screen of the present invention can promote filter efficiency effectively.
2. can save the maintenance and the renewal cost of pump by fluid circulating device of the present invention.
3. fluid circulating device of the present invention can promote manufacturing efficiency effectively, and can prevent to cause because of process disruption the problem of product rejection.
Though the present invention discloses as above with embodiment; right its is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the scope that claims define.
