Description
Technical field
The utility model belongs to centrifuge technique field more particularly to a kind of horizontal spiral centrifuge scraper installation knot
Structure.
Background technique
Horizontal spiral centrifuge is a kind of spiral discharge sedimentation centrifuge, as shown in Figure 1, solid phase passes through screw feeder 4
On blade be pushed into 2 small end slag-drip opening 21 of rotary drum discharge, liquid phase then pass through 2 big end of rotary drum overflow hole overflow.So constantly follow
Ring, to achieve the purpose that continuously to separate.But as shown in Figure 1, since centrifuge is always in high speed rotation, solid material from
Be thrown to the inside of housing 3 under the action of mental and physical efforts and be sticked to 3 inner surface of housing, it is cumulative cause to discharge it is unsmooth, especially in object
When material viscosity is larger, above-mentioned situation is particularly acute, to increase the abrasion of 2 small end of rotary drum, shortens making for rotary drum 2
With the service life, cost is increased.It is generally scraped off and is utilized outside self weight discharge machine by material scraping plate, material scraping plate is in housing 3
Ceaselessly scraping, material scraping plate are prone to wear or fracture, and service life is shorter.
Utility model content
To solve the problems, such as that the material scraping plate of horizontal spiral centrifuge of the existing technology is prone to wear or fractures, this is practical
It is novel that a kind of horizontal spiral centrifuge scraper mounting structure is provided.
In order to solve the above technical problems, technical solution used by the utility model is as follows, a kind of horizontal spiral centrifuge
With scraper mounting structure, including scraper, the scraper is fixed on the outer circumference surface of slag-drip opening one end of rotary drum, described to scrape
The rotation direction of the bottom surface of knife towards rotary drum is extended with extension board, and the bottom of the scraper is embedded in the external peripheral surface of rotary drum,
And the upper surface of extension board and the external peripheral surface of rotary drum are tangent, the junction of the scraper and extension board is cancave cambered surface.
Preferably, the side of the scraper and the upper surface of extension board are tangent with cancave cambered surface, the side of the scraper
For the inclined-plane being inclined outwardly towards cancave cambered surface.The solid and smooth concave arc face contact that scraper scrapes off, do not contact firmly, increase
Contact area, greatly reduces the stress of contact surface, mitigates the abrasion of scraper, while the side of scraper is to face out towards concave arc
Inclined inclined-plane is conducive to the solid scraped and runs outward along inclined-plane, further reduces solid to the abrasion at cancave cambered surface, extends
The service life of scraper, and structure is simple, facilitates realization, cost is relatively low.
Preferably, the other side of the bottom surface of the scraper is also extended with the extension board.The two sides of scraper extend
Have that extension board is convenient for assembly, the replaceable other side works on after a lateral wearing of scraper, extends the service life of scraper plate, drops
Low cost.
Preferably, at least two scrapers splice setting along the axis direction of rotary drum, and splicing line is folding line.It adopts
Meet the length requirement to scraper with the mode that scraper splices, improve the intensity of scraper, and the maintenance of subsequent scraper is facilitated to replace,
The scraper for only needing to change damage, reduces cost, economizes on resources；Splicing line is that folding line effectively prevent the solid to fall because turning
Bulging rotation is directly flown into seam, increases the abrasion of seam crossing, while splicing line is that folding line effectively prevent combined scraper
It fluffs under the turn of rotary drum dynamic, improves the fixing of scraper, extend the service life of scraper.
Preferably, be upwardly into the week of the rotary drum be uniformly arranged 2 groups less described in scraper.Improve the use effect of scraper
Fruit.
Further, the scraper is also equipped on the end face of slag-drip opening one end of the rotary drum.Prevent the end face of housing
The accumulation of upper solid makes to strike off more thoroughly, improves the using effect of scraper.
Further, the scraper is fixed on the outer circumference surface of slag-drip opening one end of rotary drum by screw.Structure
It is firm to stablize, easy to assembly, and cost is relatively low, is convenient for changing maintenance.
Beneficial effect：
(1) rotation direction of the bottom surface of the scraper of the utility model towards rotary drum is extended with extension board, and extension board insertion turns
In bulging external peripheral surface, and the upper surface of extension board and the external peripheral surface of rotary drum are tangent, the solid and light that scraper scrapes off
Sliding cambered surface contact, does not contact firmly, greatly reduces the stress of contact surface, mitigate the abrasion of scraper, and extend scraper uses the longevity
Life；
(2) junction of the scraper of the utility model and extension board is cancave cambered surface, the side of scraper and the upper table of extension board
Face is tangent with cancave cambered surface, reduces stress concentration, scraper is effectively prevent to fracture；The solid and smooth concave arc that scraper scrapes off
Face contact does not contact firmly, and increases contact area, greatly reduces the stress of contact surface, further mitigates the abrasion of scraper,
The side of scraper is to be conducive to the solid scraped towards the inclined-plane that cancave cambered surface is inclined outwardly to run outward along inclined-plane simultaneously, is further subtracted
Lack solid and the service life of scraper is extended to the abrasion at cancave cambered surface, and structure is simple, facilitates realization, cost is relatively low；
(3) horizontal spiral centrifuge of the utility model has stable structure reliable with scraper mounting structure, service life
The advantages that long, it is convenient to assemble, easy to use, and scraping effect is good, and cost is relatively low.
(4) scraper of the horizontal spiral centrifuge scraper mounting structure of the utility model is conducive to the stirring of solid solid
Body is discharged from slag-drip opening, and the solid deposited in housing is effectively avoided to substantially increase the abrasion of the small end outer surface of rotary drum
The service life of rotary drum.
