Abstract
The invention provides a rotary extrusion-type filter mud-discharging guide block [3] which is connected with an inner partition plate [2] forming a C-shaped channel of the filter so as to partition an charging-discharging opening of the filter; a lower side surface of the guide block is smoothly connected with the partition plate, and the lower side surface is an inclined plane which is high at the outer side and low at the inner side; the included angle between the inclined plane and a horizontal plane is 3-20 degrees. Compared with the prior art, the invention allows no fibrous substances to enter in or exit from a gap between a filter screen of the filter and the guide block, and thus the filter is prevented from being in an abnormal working state due to the fibrous substances.
Description
Technical field
What the present invention relates to is a kind of rotary extrusion type filter mud extraction guide pad, belongs to the filter technical field of the plane filtering surface that has rotation that separates in the operation.
Background technology
It is the passage around rotating shaft formation C shape of rectangle that the rotary extrusion type filter has the cross section; The passage both sides are the filter screen that is connected with rotating shaft; Be respectively the wall on the inside and outside division board inside and outside the passage; The upper end of passage connects charging aperture through feed zone, and the lower end connects discharging opening through discharging section, is equipped with on the discharging opening filter cake is applied the flashboard of resistance with control filter cake liquid content.The same parts that play buffer action that are connected with interior division board between the feed inlet and outlet are guide pad; The upper side of guide pad is the madial wall of passage feed zone and downside is the madial wall of passage discharging section; The discharging section madial wall plays the guide effect of filter cake being discharged filter simultaneously, and can be called the mud extraction guide pad this moment with guide pad.Matched in clearance is made in the filter screen of passage both sides and inside and outside division board and guide pad both sides, and filter screen rotates with main shaft during work, be filter medium be again to promote the parts that material advances in passage.Mud or solidliquid mixture that small solid particle is similarly arranged are by the material inlet admission passage, and material drives gradually through two side screens and moves to outlet.Material is thickened by rare in passage therebetween, and contained humidity is less and less and become dry, and last solid phase is discharged by the filtered solid outlet of flashboard control through tapping channel, and liquid phase is discharged by filtrate (liquid through filter screen.The upper wall of the discharging section of present normally used passage part and outlet is flatly with the smooth connection of interior division board wall; Fibrous material in practical application in the material can embed in the gap between guide pad and the filter screen, not only causes the increase of filter live load also can damage filter screen.
Summary of the invention
To above-mentioned deficiency, the present invention will provide a kind of rotary extrusion type filter mud extraction guide pad of avoiding fibrous material to embed gap between filter screen and the guide pad.
Rotary extrusion type filter mud extraction guide pad provided by the invention; It is connected with the interior division board that forms filter C shape passage and isolates the feed inlet and outlet of filter; Its downside and interior division board smooth connection; And this downside is high outside and low outside inclined-plane, and 3 ~ 20 ° angle is arranged between this inclined-plane and the horizontal plane.
Rotary extrusion type filter mud extraction guide pad provided by the invention, its downside is high outside and low outside inclined-plane, makes filter discharging section upper wall surface be higher than passage the inside part in the exit.Prove that through contrast test the filter that disposes this structure mud extraction guide pad does not embed fibrous material after use a period of time between mud extraction guide pad and filter screen, still clean after using for a long time as beginning; And the filter of configuration original structure mud extraction guide pad has more and more many fibrous materials to embed in this gap and piles up along with the continuity of service time.Compared with prior art, the present invention makes the fibrous material of can not coming in and going out in the gap between filter filter screen and the guide pad, makes filter can therefore not make duty not normal.
Description of drawings
Accompanying drawing is the structural representation of one embodiment of the invention, among the figure: the outer division board of 1-, division board in the 2-, 3-mud extraction guide pad, 4-flashboard.
The specific embodiment
Shown in the drawings is that a rotary extrusion type filter mud extraction guide pad is installed in the structure in the filter; Wherein outer division board 1 is a C shape plate body; Interior division board 2 is circular plate bodys; Interior division board places in the outer division board, and mud extraction guide pad 3 and interior division board link into an integrated entity and outside C shape division board opening part and above that downside and outside form feed inlet and outlet between the division board, flashboard 4 is installed on the outer division board of discharging opening one end.Low outer high inclined-plane and interior division board smooth connection in wherein the downside of mud extraction guide pad is, in fact this time survey face overlaps with the tangent face of interior division board downside, should be 15 ° with the tangent angle that face and horizontal plane were of interior division board downside.This angle is said between 3 ~ 20 ° from effect and structure, technological angle and is got final product, but 7 ~ 20 ° of effects are preferable, preferably at 10 ~ 20 °.
Above-mentionedly be meant inside and outside the filter inside and outside said.
Claims (3)
1. rotary extrusion type filter mud extraction guide pad; It is connected with the interior division board that forms filter C shape passage and isolates the feed inlet and outlet of filter; Its downside and interior division board smooth connection; It is characterized in that this downside is high outside and low outside inclined-plane, has 3 ~ 20 ° angle between this inclined-plane and the horizontal plane.
2. rotary extrusion type filter mud extraction guide pad as claimed in claim 1 is characterized in that 7 ~ 20 ° angle is arranged between said inclined-plane and the horizontal plane.
3. rotary extrusion type filter mud extraction guide pad as claimed in claim 1 is characterized in that 10 ~ 20 ° angle is arranged between said inclined-plane and the horizontal plane.
