Abstract
The utility model relates to a shaft-end sealing mechanism of hollow blade. The shaft-end sealing mechanism comprises a packing seal and a mechanical seal arranged in the rear of the packing seal. A material collection box is arranged between and communicated with the packing seal and the mechanical seal, and a dust ring is arranged at the communicating position of the tail end of the material collection box and the mechanical seal. The material collection box is arranged between the packing seal and the mechanical seal, a traditional integral combination mode is changed to a split mode in order to separate the packing seal from the mechanical seal by the material collection box. The probability that solid granular matters such as dust enter the mechanical seal is lowered greatly by the aid of the material collection box, and accordingly sealing performance of mechanical seal, the reliability of two-stage seal are improved, and sealing class is upgraded. By the aid of the material collection box, discharging time is prolonged, and work load is decreased. Workers can view material level in the material collection box through a sight glass hole, and a discharge valve is turned on to discharge excess materials after the material level reaches a certain height. The shaft-end sealing mechanism is high practical.
Description
Technical field
The utility model relates to a kind of sealing mechanism for shaft end, especially relates to a kind of hollow blade dryer main shaft packing seat place and stops the sealing mechanism for shaft end that leaks material.
Background technique
The sealing mechanism that hollow blade dryer shaft end seal comprises filler seat, Gland and media assemblage at present, shaft end seal mainly completes by packing seal.Because sealing road number is few, there is poorly sealed, axle head leakage material phenomenon in this sealing mechanism.
Existing sealing means has packing seal, mechanical seal, in order to increase sealability, someone is joined together both the double seal that forms integral type, but in this sealing configuration, the solid granules such as dust are easy to carry out in mechanical seal, wearing and tearing in acceleration mechanical sealing between moving plate, still, cause its working life shorter, make it lose sealability.
Model utility content
The utility model is for above-mentioned defect, and it is a kind of by improving that object is to provide, and provides a kind of rational in infrastructure simple, manufactures easily, easy to use, the sealing mechanism for shaft end of good sealing effect.
The technical solution adopted in the utility model is for this reason: the utility model comprises packing seal (12) and is arranged on the mechanical seal (9) at packing seal (12) rear portion, between described packing seal (12) and mechanical seal (9), establish Material collecting box for harvesting (8), described Material collecting box for harvesting (8) and packing seal (12), mechanical seal (9) are communicated with, the konisphere (10) of setting up defences of the connectivity part between Material collecting box for harvesting (8) end and mechanical seal (9).
Described packing seal (12): be set in main shaft (1) circumferential exterior surface, include: base ring (2) and and the filler seat (3) that coordinates of base ring (2), in filler seat (3), establish some packing seals (12), described packing seal (12) stopped by base ring (2), and the other end of filler seat (3) arranges Material collecting box for harvesting (8);
In the outer end of described filler seat (3), cooling jacket (6) is set, filler seat (3) is provided with through filler seat (3) and extends to the tracheae (4) in filler seat (3).
Between described filler seat (3), establish guard ring (13), tracheae (4) extends in guard ring (13).
Described gathering materials, (8) case was provided with visor mouth (7).
The utility model has the advantages that: 1) the utility model arranges Material collecting box for harvesting between packing seal and mechanical seal, change traditional integral type combination, become split mode, what its objective is Material collecting box for harvesting carries out separated by packing seal with mechanical seal, existence by Material collecting box for harvesting, greatly reduces the possibility that the solid granulates materials such as dust enter mechanical seal, thus the sealability of prolonged mechanical sealing, the reliability that has improved two-stage sealing, has improved sealing grade; The simultaneously existence of Material collecting box for harvesting extends the blowing time, reduces workman's operation amount, and workman can check that in Material collecting box for harvesting, material is measured by visor hole, opens discharging valve after waiting material amount to reach a certain height to emit clout, and it has very strong practicability; 2) Material collecting box for harvesting tail end is added with dust ring, has further prevented that solid granulates from entering mechanical seal, has further guaranteed the sealability of mechanical seal; 3)
By base ring, stop and effectively prevent that filler from entering in dryer casing; 4) can cooling filler by nitrogen protection and spindle end is leaked to material carry out blowback; 5) on filler seat, add water jacket to carry out effective water cooling to filler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that main shaft, 2 is that base ring, 3 is that filler seat, 4 is that tracheae, 5 is that cooling water outlet and inlet, 6 is that cooling jacket, 7 is that visor mouth, 8 is that Material collecting box for harvesting, 9 is that mechanical seal, 10 is that dust ring, 11 is that discharging valve, 12 is that packing seal, 13 is guard ring.
Embodiment
The utility model is set in main shaft 1 circumferential exterior surface, includes: base ring 2 and and the filler seat 3 that coordinates of base ring 2, in filler seat 3, establish some packing seals 12, described packing seal 12 stopped by base ring 2, the other end of filler seat 3 arranges Material collecting box for harvesting 8;
In the outer end of described filler seat 3, cooling jacket 6 is set, filler seat 3 is provided with through filler seat 3 and extends to the tracheae 4 in filler seat 3.
Between described filler seat 3, establish guard ring 13, tracheae 4 extends in guard ring 13.
Mechanical seal 9 is established in described Material collecting box for harvesting 8 ends.
Described Material collecting box for harvesting is provided with visor mouth 7.
The described Material collecting box for harvesting 8 afterbodys konisphere 10 of setting up defences.
The utility model hollow blade dryer sealing mechanism for shaft end comprises base ring 2, filler seat 3, Material collecting box for harvesting 8, mechanical seal 9.Filler seat 3 contains packing seal 12, guard ring 13, cooling jacket 6, tracheae 4 and cooling water outlet and inlet 5; Material collecting box for harvesting 8 contains visor mouth 7, dust ring 10 and discharging valve 11.Described sealing mechanism for shaft end is located at main shaft 1 and filler seat 3 places.Sealing mechanism for shaft end is comprised of main shaft 1, base ring 2, filler seat 3, Material collecting box for harvesting 8, mechanical seal 9.The interior packing seal 12 of filler seat 3 seals with main shaft 1; The interior logical cooling water of cooling jacket 6 to filler seat 3 interior packing seal 12 carry out water cooling; Nitrogen enters by tracheae 4 that nitrogen protection ring 13 is interior carries out blowback and cooling to packing seal 12; Leakage material in 8 pairs of filler seats 3 of Material collecting box for harvesting traps; Secondary seal is carried out in mechanical seal 9.Thereby solved the phenomenon of leaking material at main shaft packing seat 3 places.
