Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail, but protection scope of the present invention not limit by embodiment.
As Figure 1-Figure 4, the sealing device 2 of rotary kiln of the present invention is set on cylinder of rotary kiln 3, its one end is connected with kiln head cover or kiln hood 1 by connecting plate 4, mainly comprise: connecting plate 4, fixed head 5, front wedge 6, back wedge 7, pulley yoke 8, pulley 9, steel wire rope 10, counterweight stone roller 11, brake pad 12, bolt 13 etc., concrete structure is as follows:
Kiln head cover or kiln hood 1 are non-rotational structure, and it is fixed on foundation of civil work; Sealing device 2 is fixed on kiln head cover or kiln hood 1, and it plays the effect of sealing kiln head cover or kiln hood 1 and cylinder of rotary kiln 3; Cylinder of rotary kiln 3 is rotational structure, and material completes the operations such as preheating, decomposition, calcining in cylindrical shell; Connecting plate 4 is fixedly connected with kiln head cover or kiln hood 1, and it just makes sealing device 2 be fixed on kiln head cover or kiln hood like this; The fixed head 5 be oppositely arranged with connecting plate 4 is fixed with front wedge 6, and fixed friction block 12 between fixed head 5 and connecting plate 4, brake pad 12 between fixed head 5 and connecting plate 4, inside sealing device 2 with cylinder of rotary kiln 3 opposite position, form hermetically-sealed construction between brake pad 12 and cylinder of rotary kiln 3; Front wedge 6 is isosceles trapezoidal structure, and circumferencial direction is uniform with some; Back wedge 7 is fixed on connecting plate 4, and it is close with front wedge 6 profile, quantity is identical, and with front wedge 6 in pairs, be oppositely disposed; Pulley yoke 8 is fixed on fixed head 5, and pulley yoke 8 is symmetrical, the structure (Fig. 2, Fig. 4) of each a pair up and down; Pulley 9 is fixed on pulley yoke 8, and it is convenient to steel wire rope 10 and slides; Steel wire rope 10 is upper rope or lower rope two kinds of structures, steel wire rope 10 is arranged in the space between front wedge 6 and back wedge 7, one end of steel wire rope 10 is along the circumferential direction wound in the outside of brake pad 12, the other end of steel wire rope 10 is drawn along pulley 9, this end installs counterweight stone roller 11, realize tightening up or loosening of steel wire rope 10 pairs of brake pads 12 by increase or economization counterweight stone roller 11, brake pad 12 is moved radially along cylinder of rotary kiln 3; Counterweight stone roller 11 is fixed on the tail end of steel wire rope 10, and the quantity of counterweight stone roller 11 can be determined according to on-site actual situations; Brake pad 12 is identical with the quantity of front wedge 6 or back wedge 7, brake pad 12 be arranged between adjacent two front wedges 6 and two back wedges 7 with cylinder of rotary kiln 3 contact position, brake pad 12 is fixedly clamped by connecting plate 4 and fixed head 5, cut or polish jade with an emery wheel the increase and decrease of 11 quantity by counterweight on steel wire rope 10, brake pad 12 is circumferentially moved radially; Bolt 13 is used to fixed connecting plate 4 and back wedge 7, fixed head 5 and front wedge 6 and connecting plate 4 and fixed head 5(Fig. 3).
The course of work of the present invention is as follows:
When rotary kiln production work, because cylinder of rotary kiln 3 is rotary motions, and kiln head cover or kiln hood 1 are transfixion, therefore will there is certain gap in their junctions between the two, such hot gas and dust will flow out from kiln head cover or kiln hood 1 with cylinder of rotary kiln 3.Key principle of the present invention is: one end of steel wire rope 10 is along the circumferential direction wound in the outside of brake pad 12, and the other end of steel wire rope 10 is drawn along pulley 9, and this end installs counterweight stone roller 11; When cylinder of rotary kiln 3 deforms or abrasion occurs brake pad 12, can be adjusted by the counterweight stone roller 11 on steel wire rope 10, namely utilize steel wire rope carries with drop-down come pressing friction block 12, because brake pad 12 and front wedge 6 and back wedge 7 have certain interval, brake pad 12 can be moved radially along cylinder of rotary kiln 3, and such brake pad 12 still can contact with cylinder of rotary kiln 3 and seal.When brake pad 12 abrasion to a certain extent time, only need change brake pad 12, after this replacing, still can continue use.
