Description

A kind of centrifuge scraper mechanism

Technical field

The utility model relates to a kind of centrifuge scraper mechanisms.

Background technique

Centrifuge is to be separated solid-liquid by the effect of centrifugal force, the solid portion after separation need by scraper from Lower discharging is hung on inner wall, existing scraper is to guarantee that scraper does not damage inner wall filter cloth in the case where scraping off discharging, often makes scraper Certain distance is kept with inner wall, so that remaining discharging is caused, it, for a long time can be to centrifugation if remaining discharging has corrosivity Machine inner wall causes to damage, and influences centrifuge whole service life and causes to a certain extent to next batch material processing quality It influences.

Utility model content

Filter cake can be preferably removed the technical problem to be solved by the utility model is to provide one kind and does not damage filter cloth Centrifuge scraper mechanism.

In order to solve the above technical problems, the technology employed by the present utility model is a kind of centrifuge blade construction, Including turning set, the cursor of tubulose is connected on turning set periphery, cursor is equipped with main scraper far from one end of turning set, main The knife face of scraper is parallel to cursor section, and nearly turning set one end is equipped with the adjustable spring of pretightning force in the cavity of cursor, turns Inner shaft is equipped in swing arm, inner shaft one end is connect with spring, cursor end be equipped with annular end cap, inner shaft be pierced by annular end cap and Annular end cap and interior between centers are equipped with sealing ring, and the inner shaft outer end is equipped with bottom material scraper, and bottom material scraper is equipped with positioning wheel seat, fixed It is offered on the wheel seat of position perpendicular to main scraper cutting edge locating wheel slot, positions and be equipped in race for making the cutting edge of bottom material scraper and turning The locating wheel of 1-2mm is retained between drum wall.

As a preferred embodiment, the secondary scraper for being parallel to main scraper is equipped in the middle part of the cursor.

As a preferred embodiment, the inner shaft is equipped with axially directed slot, is equipped with end on cursor and protrudes into guiding Feather key in slot.

As a preferred embodiment, mounting blocks are welded on the cursor, mounting blocks are equipped with to be passed through for feather key Through-hole, the feather key outer end are connected with clamping cap, are equipped with sealing ring in feather key periphery between clamping cap and mounting blocks, compress Lid is connected by housing screw with mounting blocks.

As a preferred embodiment, the inner shaft is located at the both ends in cursor offers annular groove respectively, annular Guide sleeve is equipped in groove.

As a preferred embodiment, the locating wheel is polytetrafluoroethylene (PTFE) locating wheel.

The beneficial effects of the utility model are: due to this blade construction relative to existing technique add locating wheel with Bottom material scraper, main scraper strike off the material of rotatory drum wall upper epidermis, and bottom material scraper strikes off internal layer material on rotatory drum wall, and locating wheel is not only Make to retain 1-2mm between the cutting edge and rotatory drum wall of bottom material scraper, avoids bottom material scraper from scratching filter cloth, and the elastic reaction of spring makes The indentation filter cloth gap that filter cloth will not be excessively tight by material will not be damaged by obtaining locating wheel, so that this scraper mechanism is cleared up Efficiently thoroughly, and after avoiding material indentation filter cloth filter-cloth filtering effect is influenced.

Due to being equipped with sealing ring between annular end cap and interior between centers and clamping cap and mounting blocks, effectively prevents inner shaft and turn The gas that dynamic inner room contains lubricant grease particle penetrates into contaminated material in rotary drum.

Due to carrying out scraping to material using secondary scraper, secondary scraper and main blade combination, secondary scraper can be scraped off on rotatory drum wall The material of middle layer alleviates the scraper resistance of bottom material scraper, so that filter cake cleaning is more thorough, while extending bottom material scraper Service life.

Due to being oriented to for inner shaft, avoiding the shake of inner shaft during scraper using guide sleeve and guiding key combination It quivers, improves the job stability of equipment.

Due to using polytetrafluoroethylene (PTFE) as locating wheel material, the resistance to corrosion of locating wheel is enhanced, it is fixed to improve The service life of position wheel.

Specific embodiment

With reference to the accompanying drawing, the specific embodiment of the utility model is described in detail.

As shown in Figure 1-3, a kind of centrifuge blade construction, including turning set 1, turning set are connected with tubulose on 1 periphery Cursor 2, cursor 2 is equipped with main scraper 3 far from one end of turning set, and the knife face of main scraper 3 is parallel to 2 section of cursor, The secondary scraper 11 for being parallel to main scraper 3 is equipped in the middle part of cursor 2, nearly turning set one end is equipped with pretightning force in the cavity of cursor 2 Adjustable spring 4, mounting blocks 13 are welded on cursor 2, and mounting blocks 13 are equipped with through-hole, are equipped with feather key 12, institute in through-hole It states 12 outer end of feather key and is connected with clamping cap 14, be equipped with sealing ring 7 in 12 periphery of feather key between clamping cap 14 and mounting blocks 13, Clamping cap 14 is connected by housing screw with mounting blocks 13.Inner shaft 5 is equipped in cursor 2, inner shaft 5 is equipped with axially directed Slot, the feather key 12 worn on cursor 2 protrude into guide groove.5 one end of inner shaft is connect with spring 4, and inner shaft 5 is located in cursor 2 Both ends at offer annular groove respectively, guide sleeve 15 is equipped in annular groove.2 end of cursor is equipped with annular end cap 6, interior Axis 5, which is pierced by between annular end cap 6 and annular end cap 6 and inner shaft 5, is equipped with sealing ring 7, and 5 outer end of inner shaft is equipped with bottom material scraper 8, bottom Expect that scraper 8 is equipped with positioning wheel seat 9, positions and offered on wheel seat 9 perpendicular to main 3 cutting edge of scraper positioning race 9, position race 9 It is interior to be equipped with the polytetrafluoroethylene (PTFE) locating wheel 10 that 1-2mm is retained between cutting edge and rotatory drum wall for making bottom material scraper 8.

When work:

By after feed separation, rotary drum starts direction as shown in Figure 3 and rotates centrifuge, and rotation axis (not shown) is logical Crossing turning set 1 drives cursor 2 to start to rotate opposite direction rotation, the scraper knot when locating wheel 10 touches drum inner wall to rotary drum Structure stops rotating, when drum rotating main scraper 3, secondary scraper 11, bottom material scraper 8 start to strike off the material on drum inner wall, scraper After, rotary drum stops rotating, blade construction spinning reduction.
