The specific embodiment
Shown in Fig. 1～6, it comprises main shaft 18, it is by the coaxial segmentation rotating shaft that connects to form of connector, this main shaft vertically places the center of pond body 21, main shaft 18 lower ends are connected with agitator arm 19, the main shaft upper end is coaxially connected with the output shaft 30 of main shaft driving device 5 by axle sleeve 26, this main shaft driving device 5 supports by the turntable 4 that is arranged on the support 6, output shaft 30 outer ends of main shaft driving device 5 have been horizontally disposed with a ring-like lug connector 24, this ring-like lug connector 24 is connected with revolution plate washer 29 by bolt, the side upper level of this revolution plate washer 29 is provided with gyroaxis 34, the end of gyroaxis 34 in the revolution plate washer is set with spring 35, the gyroaxis other end is connected with another the ring-like lug connector 25 that is fixed on turntable 4 upper level settings by bolt, be provided with pull bar 31 in the gyroaxis upper parallel in gyroaxis, this pull bar is provided with the flexible contact heads 33 that slide synchronously of spring 35, also is provided with warning travel switch 32 and overload shutdown travel switch 28 by starting with the contact head collision on the revolution plate washer of the sliding stroke position of contact head;
Crane span structure comprises fixedly crane span structure 2 and rotation crane span structure 8, fixedly crane span structure 2 is arranged between supporter 23 and the material chamber 7, in fixing crane span structure 2, be provided with the chute 1 corresponding with feed port 3, rotating crane span structure 8 is arranged between pond body circumference and the crane span structure rotation platform 14, rotation crane span structure near pond body circumference is provided with running gear 12, be evenly equipped with 10, four hydraulic lift(ing) cylinders 10 of four each and every one hydraulic lift(ing) cylinders on this rotation crane span structure and be connected with four mud scrapers 9 downwards respectively.Also comprise gape 20, downflow weir 22 in the accompanying drawing.
During work, the present invention is installed in the Chi Tizhong of three kinds of angles, angle with horizontal plane at the bottom of the pond, center is big more, the rake degree of depth of putting of four mud scrapers increases with the angle of horizontal plane angle at the bottom of with the pond, as shown in Figure 1, make ore pulp center deep layer pan feeding, reduced settling height, the advection sedimentation, make things convenient for the collection of scraping of sedimentation material, the thickening efficiency height.During pan feeding, ore pulp flows into feed port 3 through chute 1 and enters material chamber 7, the material chamber is downwards also successively through pipe spreader 13, shunting bucket 15 and current stabilization bucket 16, steadily flow at the bottom of the pond uniformly then, under the effect of gravitational field, solid particle in the ore pulp sinks down at the bottom of the pond gradually, and primary water evenly rises to liquid level.Main shaft driving device 5 drives that main shafts rotate agitator arms 19 and puddler 27 also rotates thereupon, thereby makes material loosening play body bottom, pond to stir the mud effect of scraping with carrying on the material.The driving force that running gear 12 usefulness of chain drive are suitable drives rotates crane span structure 8 and rotates, and mud scraper 9 rotates thereupon, scrapes collection central row mine mouth 20 at the bottom of the pond, discharge pond body with being deposited on concentrated material at the bottom of the pond; The primary water that rises to liquid level is then discharged the pond bodies by downflow weir 22, thereby finishes the overall process of the concentrating of ore pulp, discharge, clarification, overflow.
When scraping the increase of mud resistance, this resistance is passed to drive unit output shaft 30 by main shaft 18, the ring-like lug connector 24 that is connected with drive unit output shaft 30 is exerted pressure to spring 35 by torque reaction, the spring that is under pressure is compressed along gyroaxis 34, driving contact head 33 slides in the same way along pull bar, slip and 32 collisions of warning travel switch along with contact head 33, the warning circuit conducting, after control system is received alarm signal, height that can be by control hydraulic lift(ing) cylinder 10 lifting mud scrapers 9 or reduce feeding and reduce to scrape the mud resistance, wherein hydraulic lift(ing) cylinder can be controlled mud scraper and is promoted to more than the liquid level, simultaneously also convenient for maintaining; If but it is increasing to scrape the mud resistance; torque reaction further compresses spring; contact head 33 is slided and 28 collisions of overload shutdown travel switch; at this moment main shaft driving device 5 outages; the reaction force of spring produces output shaft and the main shaft counter-rotating that a bounce-back moment drives main shaft driving device; to deposition material bounce-back vibrations, make material loosening, be beneficial to start once more drive unit.Control system of the present invention is the PLC central control system, can participate in the collection control of full factory, is provided with automatic, manual two kinds of working methods.Can realize purpose of the present invention in sum.
