Embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.
The invention discloses a kind of granular membrane, as shown in Fig. 1 ~ 3, including main body 100 and body interior is arranged on
Filtration, main body 100 is provided with the charging aperture 110 and discharging opening 120 connected with filtration, while being set inside main body 100
Put an installation through-hole 130（Referring to Fig. 2 and 3）.Filtration includes mandrel 210, the lower end of mandrel 210 insertion installation through-hole
In, the lower end of mandrel 210 is provided with filter house 220, and buffering cavity 230, the buffering are formed between the filter house 220 and main body 100
Cavity 230 is around parcel filter house 220, the connection buffering cavity 230 of charging aperture 110；As shown in figure 3, the inside of filter house 220 is set
Filter cavity 222 is equipped with, the one end of filter cavity 222 connection discharging opening 120, the surface of filter house 220 is provided with several filterings and led to
Hole 221, the filtering connection of through hole 221 buffering cavity 230 and filter cavity 222；In practical application, filtration also includes screen cloth
（Do not drawn in figure）, screen cloth, which is arranged on, to be buffered in cavity 230, and screen cloth is set around parcel filter house 220 surface.Such as the institutes of Fig. 2 and 3
Show, melt is flowed into from charging aperture 110, be first filled with buffering cavity 230, be to surround to wrap up due to buffering cavity 230 and screen cloth
The surface of filter portion 220, therefore the whole surface of filter house 220 is filtering surface, melt passes through screen cloth and the surface filtration of filter house 220
Through hole 221 is filtered, and is entered from buffering cavity 230 in filter cavity 222, is finally flowed out from discharging opening 120（The flowing side of melt
To in referring to Fig. 2 and 3 shown in arrow）.By this setup, the filtering surface of filter house 220 is on the one hand greatly increased
Product, improves filter efficiency and the utilization rate of screen cloth, is not easily blocked screen cloth, extend its service life, on the other hand, changes
The path of melt flows, allows melt sufficiently to be filtered by screen cloth and the surface filtration through hole 221 of filter house 220, improves filtering
Effect.
In practical application, for the ease of processing and increasing the filtering surface of filter house 220, filter house 220 is arranged to cylindric,
Screen cloth is arranged to matched cylindrical shape simultaneously, as shown in Figures 2 and 3, and buffering cavity 230 is cylindric cavity, this set
Structure can increase the volume of buffering cavity 230, while making whole filtration compacter.Certainly, in practical application, filtering
Portion 220 and buffering cavity 230 can also be arranged to other shapes, such as being arranged to quadrangular shape or hexa-prism.
Further, in order that the melt of the bottom of filter cavity 222 can be flowed up, it is to avoid it is deposited, while in order to
The effect for holding runny speed and filtering is improved, as shown in Figures 2 and 3, filter cavity 222 is internally provided with flow-guiding bar 240, should
The cross section of flow-guiding bar 240 diminishes with the increase of height.The flow-guiding bar 240 of this structure makes the inside of filter cavity 222 empty
Between to height be directly proportional（I.e. more past beneath, space is smaller）, this results in the pressure that bottom melt is subject to and is greater than top melt,
Bottom melt is constantly slowly flowed up, then discharged from discharging opening 120.
In a preferred embodiment, flow-guiding bar 240 is conical flow-guiding bar.
Further, as shown in Figures 2 and 3, flow-guiding bar 240 is inserted upwardly into filter cavity 222 from the bottom of filter cavity 222
In, the bottom of flow-guiding bar 240 is provided with the leakproof boss 241 of sealing filter cavity bottom, the leakproof boss 241 and filter house 220
Bottom inside wall is chimeric to be set.Meanwhile, as shown in figure 4, at the chimeric of leakproof boss 241 and the bottom inside wall of filter house 220
Sealed groove 261 is provided with, while setting sealing ring 262 in sealed groove 261, this set structure can be completely secured
Leak case does not occur for filter cavity 222, while this structure of the present invention installs simple and fast, it is practical.
Further, as shown in Fig. 2 ~ 4, in order to prevent buffering cavity 230 from occurring leak case, the bottom of filter house 220 is set
Seal 250 is equipped with, seal 250 is screwed connection filter house 220 bottom, and it is slow that the seal 250 is provided with sealing
The seal boss 251 of the bottom of cavity 230 is rushed, seal boss 251 is chimeric with the bottom outside wall of filter house 220 to be set.Likewise,
Seal boss 251 at the chimeric of the bottom outside wall of filter house 220 with being provided with sealed groove 261, while in sealed groove 261
Sealing ring 262 is set, further to improve leakage-preventing effect.
In practical application, referring to Fig. 3 and 4, fixed for the ease of the mounting box of screen cloth, allow its stablize be attached to
The surface of filter portion 220, it is ensured that its filter effect, is provided with the compressing member 270 for clamping screen cloth, the pressure at the top of the outer wall of filter house 220
Tight part 270 is provided with pressing groove 271, and pressing groove 271 is provided with V-arrangement opening 271（Identical structure, which is referred to, seals convex in Fig. 4
The structure at the top of platform 251）, to complete to being fixedly clamped at the top of screen cloth；Likewise, the top of seal boss 251 is provided with compression
The pressing groove 271 and V-arrangement opening 272 of screen cloth, to complete to be fixedly clamped to screen bottom.
In practical application, the clean and maintenance of the replacing of screen cloth and filter house 220 for convenience, referring to Fig. 2, filtration is also
Including being connected with the top of mandrel 210 and mandrel 210 being released into the dynamic structure 280 that main body 100 carries out screen cloth replacing.Specifically,
The dynamic structure is oil cylinder or cylinder.In use, whole mandrel 210 is pushed down on by oil cylinder, make filter house 220（Including
Seal 250）Move downward and removed from the installation through-hole 130 of main body 100, expose screen cloth and filter house 220, utilize instrument
Seal 250 is removed, screen cloth is extracted out after being cleaned or being changed, the surface of filter house 220 is socketed in again, is pacified again
Seal 250 is loaded onto, control cylinder pulls up mandrel 210, filter house 220 is embedded in again in main body 100, buffer cavity 230
With charging aperture 110, filter cavity 222 and discharging opening 120 again corresponding connection.This set structure, screen cloth changes simple and convenient,
Efficiency high is changed, is conducive to the maintenance and maintenance of whole granular membrane, it is ensured that its filter effect.
In practical application, in same main body 100, filtration can set multiple, as shown in figure 1, filtration
Two are set, this setup is realized when changing the screen cloth of one of filtration, another filtration is still
Carrying out filtration（Even if the setting of buffering cavity and filter cavity makes only one of which filtration work, it is possibility to have foot
Enough spaces make melt all smoothly flow through, while can ensure the filter effect of melt）, i.e., more change jobs can't for screen cloth
Shut down whole granular membrane, it is ensured that the continuous firing of granular membrane.Further, multiple filtrations are even
Same charging aperture and discharging opening can be shared, the structure of main body 100 is simplified, the difficulty and cost of production and processing is reduced.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can
To be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect scope.
