Abstract
The invention relates to a rotary-drum vacuum filter for dewatering fluorite ore pulp. The rotary-drum vacuum filter comprises a filter rotary drum and a scraper system. The scraper system comprises a scraper. The scraper includes a main scraper and an auxiliary scraper which are in rotary connection. The edge of the main scraper attaches to the surface of a filter plate. The scraper further comprises at least one connecting part. Two ends of each connecting part are respectively fixed on the scraper bodies below the main scraper and the auxiliary scraper. The auxiliary scraper is fixed on a support. Under the limitation of the support, the connecting parts and the filter plate, the included angle between the auxiliary scraper and the filter plate is smaller than the included angle between the main scraper and the filter plate. Compared with the prior art, the rotary-drum vacuum filter has the advantages that by the coordination of the main scraper and the auxiliary scraper and limitation of the connecting parts and the filter plate to the main scraper, the main scraper can rotate in a certain range, the moving range of the main scraper is limited, the main scraper can be matched with the rotary drum in real time to subtly move, and the filter plate is protected from being damaged.

Preferably, described connection member is connecting rod.
Preferably, described connection member is 2.
Preferably, described 2 connection members are parallel to each other.
Preferably, one end of described connecting rod has elastic component.
Preferably, described elastic component is spring.
Preferably, the blade of described operator is the curved slab being attached at described filter plate surface; Described curved slab extends to described filtration rotary drum top along described filter plate from the operator knife back.
Preferably, described operator is for adopting spring steel plate to prepare operator.
Preferably, the rotating shaft between described secondary cutter and described operator is parallel with the axis of described filtration rotary drum.
Preferably, described operator is hinged with described secondary cutter.
The present invention compared with prior art, has the advantages that
The present invention by being divided into operator and secondary cutter by scraper, secondary cutter position is fixed, the mode that operator is hinged with secondary cutter, the blade of operator rides on filter plate, for stable operator, the present invention also adopts connecting rod to fix in the lower section of operator with secondary cutter, makes the secondary cutter angle with filter plate less than the angle operated with filter plate; One end of connecting rod has spring, it is possible to make the angle between operator and filter plate change in good time; It is so designed that, namely can meet operator and rotate within the specific limits, again limit the range of activity of operator; In order to protect filter plate injury-free; the present invention is also at the curved slab that the blade of operator is designed to attaching and filter plate surface; and operator adopts spring steel plate to make; in rotary drum rotation process; except operating and itself can adjusting position; curved slab can also cushion a part of displacement, thus reaching the damage of filter plate is minimised value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of rotary drum vacuum filter for fluorite pulp dewatering of the present invention.
Detailed description of the invention
For making the architectural feature to the present invention and effect of reaching have a better understanding and awareness, coordinate detailed description in order to preferred embodiment and accompanying drawing, illustrate as follows:
As it is shown in figure 1, a kind of rotary drum vacuum filter for fluorite pulp dewatering, including rotary drum; The surface of described rotary drum has filter plate 71. Filter also includes doctor blade system, and doctor blade system includes scraper 72 and the support 73 for fixed doctor 72. Scraper 72 includes operator 721 and secondary cutter 722. Secondary cutter 722 side is horizontally fixed on support 73, and the opposite side of secondary cutter 722 is rotationally connected with the knife back of operator 721. The blade of operator 721 is attached at filter plate 71 surface. Scraper 72 also includes at least one connection member 74, and one end of connection member 74 is fixed on the blade below operator 721, and the other end is fixed on the blade below secondary cutter 722.
Operator 721 provided by the invention can be that articulated form is hinged with secondary cutter 722. Support 73, connection member 74, filter plate 71 spacing under, the angle of secondary cutter 722 and filter plate 71 is less than the angle of operator 721 with filter plate 71.
Connection member 74 provided by the invention has the connecting rod of elastic component 741 for one end, and elastic component 741 can be spring, and the requirement of strength of spring is higher, and the length of spring is not easily long, to limit operator 721 rotation in less angle.
The quantity of connection member 74 can be 2, and 2 connection members 74 are in same plane, and are parallel to each other, and are evenly arranged on scraper 72.
In order to cushion operator 721 and filter plate 71 between touching power, the present invention also by operator 721 blade be the curved slab 7211 being attached at filter plate 71 surface;Curved slab 7211 extends along filter plate 71 to filtering rotary drum top from operator 721 knife back. The width of curved slab 7211 is about 17m. Operator 721 can adopt spring steel plate to prepare, and the bending place toughness between curved slab 7211 and operator 721 blades is big, it is possible to meet the requirement of the trickle displacement of rotary drum.
Secondary cutter 722 provided by the invention is horizontally disposed with operator 721, and rotating shaft therebetween is parallel with the axis of rotary drum.
It is further fixed on chute 75, for breeze is imported container wherein in the lower section of secondary cutter 722. In order to avoid breeze is scattered, it is respectively fixed with baffle plate 76 in the both sides of chute 75 and scraper 72.
