preferably, described doctor blade device also comprise be located at first side plate of described upper position plate on the broadside of described blade shaft side, the second side plate be located on long limit, described upper position plate side.
further preferably, described first side plate, described second side plate and the one-body molded setting of described upper position plate.
preferably, described directed unloader knife device also comprise be located on described scraper base for the lift drive mechanism driving described blade shaft to be elevated, the rotary drive mechanism that drives described blade shaft to rotate.
further preferably, described lift drive mechanism is hoist cylinder, and described rotary drive mechanism is rotary oil cylinder.
preferably, described scraper comprises the secondary wing and main wing that set gradually along described scraping cutter bar bearing of trend.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages: a kind of directed unloader knife device for lower discharging centrifuge described in the utility model, by arranging position plate above scraper, when scraper precession material carries out shaving, the direction of motion of material is defined by the position plate above scraper, the lighter material of proportion is effectively prevented to fly out from lip ring upper end in shaving process, cause the loss of material, this structure is simple, easy to operate.

Detailed description of the invention
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in Figure 2, a kind of unloader knife device 3 of lower discharging centrifuge, comprise the scraper base 31 being installed in centrifuge casing 1 top, be located at the blade shaft 32 of liftable and rotation on scraper base 31, the scraping cutter bar 32 being installed in blade shaft 32 end and the scraper be located on scraping cutter bar 32, this doctor blade device also comprises the position plate for preventing materials from spattering during discharging be installed in above scraper, this position plate comprises the upper position plate 51 be installed in above scraper, be located at first side plate 52 of position plate 51 on the broadside of blade shaft 32 side, be located at the second side plate 53 on long limit, position plate 51 side, the two ends of this first side plate 52 respectively with upper position plate 51, blade shaft 32 is connected, when scraper, the medial surface of this second side plate 53 contacts with material.Preferably, this first side plate 52, second side plate 53 and the one-body molded setting of upper position plate 51.This directed unloader knife device 3 also comprise be located on scraper base 31 for drive blade shaft 32 to be elevated lift drive mechanism, drive blade shaft 32 rotate rotary drive mechanism, in the present embodiment, this lift drive mechanism is hoist cylinder, and rotary drive mechanism is rotary oil cylinder.
the course of work of unloader knife device 3 of the present utility model is: during centrifuge work, material enters in rotary drum 2, liquid in material throws away by the rotary drum 2 of High Rotation Speed, discharge from discharging tube 4 after being built up by casing 1, solid phase in material to be trapped in rotary drum 2 simultaneously and to form annular solid solid-phase material, when then starting to strike off solid-phase material after centrifuge reduction of speed.During scraper, first the rotary oil cylinder on scraper base 31 is utilized to drive blade shaft 32 to drive in scraper precession solid-phase material, then, after scraper arrives the screen position of rotary drum 2 madial wall, then the action of the oil cylinder that stops the rotation, utilizes the scraper hoist cylinder on scraper base 31 to drive blade shaft 32 to drive the downward shaving material of scraper, in the process, by being arranged on the position plate above scraper, preventing the lighter material of some proportions to fly up with scraper, flying out above lip ring and causing the waste of material.In order to ensure can by material scraped clean, in the present embodiment, scraper comprises the secondary wing 34 and main wing 35 that set gradually along scraping cutter bar 32 bearing of trend, and according to the size of rotary drum 2, can select the quantity of wing.When scraper arrives bottom rotary drum 2, scraper rotary oil cylinder on scraper base 31 drives blade shaft 32 to drive scraper to screw out material, and now, material is by scraped clean, then drive blade shaft 32 to drive scraper upwards to return to original position by scraper hoist cylinder, complete scraper operation.In order to prevent scraper in scraper process with the screen contact on rotary drum 2 madial wall, cause the breakage of screen cloth, when scraper, between scraper and screen cloth, leave certain space.
in sum, the directed unloader knife device of lower discharging centrifuge of the present utility model, by arranging position plate above scraper, make in scraper process, define the direction of motion of material, efficiently avoid in prior art, the material that some proportions are relatively light flies up with scraper when scraper, splash to lip ring outside, cause the situation of material loss to occur.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
