Material returned pipe 4 surface offers discharging opening 7, and being located proximate to of discharging opening 7 scrapes cutterhead 8, scrapes cutterhead 8 for circle, scrapes the circumference of cutterhead 8
Edge is provided with two arc transition limits 85, and two arc transition limits 85 are arranged axisymmetricly with a diameter of axis of symmetry scraping cutterhead 8,
Scrape and on cutterhead 8 circumferential edges, form two sunk areas, sunk area in its region being provided with between two arc transition limits 85
Being provided with transition blade 83, transition blade 83 one end is provided with the first main scraper 81, the other end is provided with the second main scraper 84, and the
One main scraper 81, transition blade 83 and the second main scraper 84 set gradually in clockwise direction, and arc transition limit 85 is pressed
Being sequentially provided with the first auxiliary scraper 86 and the second auxiliary scraper 87 according to clockwise direction, transition blade 83 and the second main scraper 84 are formed
Main mud drain outlet 813, the first main scraper 81 is arranged on arc transition limit 85, and arc transition limit 85 is provided with first
The end of main scraper 81 is main mud drain outlet charging aperture 810, the second main scraper 84 at it away from the end of transition blade 83
Being main mud drain outlet discharging opening 811, the first auxiliary scraper 86, arc transition limit 85 and the second auxiliary scraper 87 form auxiliary mud row
Dirty passage 88, the second auxiliary scraper 87 forms auxiliary mud drain outlet charging aperture 812 at it near the end on arc transition limit 85, the
Two auxiliary scrapers 87 form auxiliary mud drain outlet discharging opening 89 at it away from the end on arc transition limit 85, transition blade 83 according to
The direction of the first main main scraper of scraper 81 to the second 84 is inclined and mounted on sunk area, and arc transition limit 85 is provided with first at it

According to an embodiment of the present utility model, scraper 6 spacing size between any two is from scraping cutterhead 8 to charging aperture 5
Direction increases successively.
According to an embodiment of the present utility model, concentrate and offer mud mouth 9 on end wheel disc axle 3, concentrating end wheel disc
In axle 3 rotary course, mud mouth 9 overlaps with discharging opening 811 or auxiliary mud drain outlet, main mud drain outlet discharging opening 89.
Operation principle of the present utility model is as follows:
First passing through the differential mechanism on thickener drives spiral pusher pipe 4 to rotate, thus produces centrifugal force, will be from charging aperture
5 sewage entered in spiral pusher pipe 4 get rid of into rotary drum 2 internal from discharging opening 7, and the motor on thickener drives rotary drum to turn simultaneously
Dynamic, according to centrifugal force company, the material of different densities can produce different centrifugal force, and described sewage can be layered in rotary drum 2, close
Spending big mud can be near the inwall at rotary drum 2, and the clear liquid that density is little can be near spiral pusher pipe 4, and at this moment differential mechanism drives
Spiral pusher pipe 4 and motor-driven rotary drum 2 rotating in same direction, due to the fast 1-of rotating speed of the rotating ratio rotary drum 2 of spiral pusher pipe 4
10rpm, so at this moment spiral pusher pipe 4 moves relative to rotary drum 2, so that before the scraper 6 on spiral pusher pipe 4 promotes material
Enter, owing to the edge of the most close rotary drum 2 of scraper 6 is continuous steel plate, so the clear liquid being positioned at lower floor will not be promoted by scraper 6,
So scraper 6 only can promote mud to move towards scraping cutterhead 8 direction, in mud, most mud can rotate so along with rotary drum 2
After smash through the first main scraper 81 and laggard to become owner of mud drain outlet charging aperture 810, scrape along transition blade 83 and second are main
Moving in the main mud drain outlet 813 that cutter 84 is formed, in the guide effect through the second main scraper 84, is introduced into main mud row
Dirty passage ports 811, owing in rotation process, main mud drain outlet discharging opening 811 can overlap with mud mouth 9, so at this moment
Just substantial amounts of mud can be discharged, then not by main mud drain outlet in mud from the mud mouth 9 concentrated end wheel disc axle 3
The 813 a small amount of mud discharged can be then passed through entering auxiliary mud blowdown after the first auxiliary scraper 86 is smashed along with rotary drum 2 is rotated further
Passage charging aperture 812, moving in the auxiliary mud drain outlet 88 formed along arc transition limit 85 and the second auxiliary scraper 87, is passing through
The guide effect of the second auxiliary scraper 87, is introduced into auxiliary mud drain outlet discharging opening 89, due to auxiliary mud row in rotation process
Dirty passage ports 89 can overlap with mud mouth 9, so the most just can be by remaining a small amount of mud from concentrating end wheel disc axle 3
Mud mouth 9 is discharged.
Essence of the present utility model is described in detail by above detailed description of the invention, but can not be to of the present utility model
Protection domain limits, it should be apparent that, under enlightenment of the present utility model, the art those of ordinary skill is all right
