FIG. 2 is a schematic view of a filter screen usage state structure according to the present invention;
fig. 3 is a schematic perspective view of the exhaust gas filter.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in figure 1, the filter screen for separating air in a pipeline is made of plastic, is of an injection molding integrated structure and comprises a mesh-shaped substrate 1 formed by crossing a longitudinal substrate strip 10 and a transverse substrate strip 11; the crossing position of the longitudinal base strip 10 and the transverse base strip 11 is a cross joint 12, the side of the cross joint 12 is provided with corner columns 13, and the corner columns 13 are arranged on the reticular base 1 in an array mode.
The plastic material of the filter screen is made of nylon, polyethylene, reinforced ABS, polyformaldehyde and other plastic materials, has certain high temperature resistance, can be subjected to injection molding, is simple in process compared with a metal net, is quick to mold, low in cost and good in corrosion resistance in an aqueous medium, and is tough, can be bent, and is suitable for application of more pipeline specifications through combined deformation.
The longitudinal base strips 10 and the transverse base strips 11 cross to form the net-shaped base 1, the meshes of the net-shaped base 1 are square, and the cross joints 12 are on the same surface with the longitudinal base strips 10 and the transverse base strips 11. The side of the cross joint 12 is provided with a prism 13, in the figure, the prism 13 is positioned on the longitudinal base strip 10, when the filter screen is rolled into a cylinder shape or folded along the transverse base strip 11, the prism 13 is staggered with the cross joint 12 and the transverse base strip 11, and can not be abutted. This structural feature makes the filter screen when the batching tube-shape or fold condition use, forms reasonable and compact space between the layer for corner post 13 is fit for with aqueous medium contact interval, and the aqueous medium of flowing through produces different velocity of flow and pressure, extrudes the tiny air wherein, and exhaust efficiency is high in certain space, and is effectual. Compare traditional passive discharge valve structure, through cutting aqueous medium, the microbubble in the aqueous medium is extruded in the initiative, and exhaust effect is more thorough.
In order to achieve that the flowing water medium generates more changes in direction, flow speed and pressure, the corner column 13 adopts the characteristic that the transverse section is square and is in a structure with a large lower part and a small upper part. The square structure enables the corner columns 13 to have obvious corners, different from a cylinder, the square corners have guiding and impacting characteristics on water flow, flowing water media generate more violent mutual collision and change of local water density, and fine air is extruded more effectively. The transverse section of the corner column 13 can also be a triangular structure with a large lower part and a small upper part. The longitudinal base strip 10 and the transverse base strip 11 are strip-shaped cuboids, and are also beneficial to generating impact on a flowing water medium.
The corner columns 13 are arranged on the mesh-shaped substrate 1 in an array mode, the structure enables the filter screen to form a three-dimensional cutting structure for the water medium in a use state, the three-dimensional cutting structure is different from a single-layer filter screen, the water medium flowing through the cutting structure is more thorough, microbubbles are enriched on the three-dimensional filter screen structure, the contact surface is larger until the microbubbles float upwards, and the effect of discharging fine air in the water medium is good.
As shown in the schematic structural diagram of the using state of the filter screen shown in fig. 2, when the filter screen is used, the corner columns 13 are inward and integrally rolled into a cylinder 2; is put into the exhaust valve cavity 5 with the corresponding size of the cylinder 2, as shown in figure 3. The shape and structure of the exhaust valve cavity are various, and the similar exhaust valve cavity structure is also shown as CN 203215038U 'micro-bubble exhaust valve' and the like.
The corner columns 13 are rolled inwards to form a cylinder 2, so that the filter screen forms a more complex three-dimensional barb structure, and the effect of extruding air 4 out of the water medium 3 flowing through is better. The cylindrical 2 state can be formed by rolling one filter screen or a plurality of filter screens, and the size of the rolled outer diameter is adjusted according to the size of the exhaust valve cavity.
And the filter screen is folded into a square body for multiple times when in use and is placed in the exhaust valve cavity with the corresponding size of the square body. The exhaust valve cavity is matched with the square body.
The pipeline filter screen can be bent and folded, is provided with the array corner columns with distinct corners, forms a three-dimensional barb structure through deformation and combination, cuts a flowing water medium, extrudes fine air in the flowing water medium, and is more thorough in filtering and exhausting; the product is integrally formed by plastic, has good corrosion resistance and low cost, is suitable for exhaust occasions of pipelines with different flow calibers, has novel structure and has market popularization value.
