[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a partial structural schematic diagram of the utility model.

[0014] Among them: 1-fan inlet, 2-fan casing, 3-fan shaft, 4-motor shaft, 5-asbestos gasket seal, 6-asbestos gasket fixing bolt, 7-straight pipe one, 8-ball valve one, 9-straight pipe two, 10-throat clamp one, 11-steel wire hose one, 12-fixing buckle, 13-throat clamp two, 14-straight pipe three, 15-collection box, 16-bolt, 17-straight pipe four, 18-ball valve two, 19-thread pair, 20-throat clamp three, 21-steel wire hose two, 22-angle steel. DETAILED DESCRIPTION

[0015] The following is combined with Figure 1 , 2 The specific implementation methods of the utility model are further described.

[0016] The spinnable asphalt flue gas fan shaft seal leakage collection device comprises a collection box 15, which is detachably mounted on the fan shaft 3, the motor shaft 4, the asbestos pad seal 5, and the asbestos pad fixing bolt 6. The collection box 15 is divided into an upper and lower part, which are connected by bolts 16. The collection box 15 is sealed and connected to the fan housing 2 by a sealant, and an angle steel 22 is welded between the collection box 15 and the fan housing 2; the lower part of the collection box 15 is connected in sequence with a straight pipe 4 17 and a ball valve 2 18 , wire pair 19, steel wire hose two 21, the wire pair 19 and the steel wire hose two 21 are fixed by a throat clamp three 20; the top of the collecting box 15 is connected with the straight pipe three 14, the steel wire hose one 11, the straight pipe two 9, the ball valve one 8, the straight pipe one 7, the fan inlet 1 in sequence, the straight pipe three 14 and the steel wire hose one 11 are fixed by a throat clamp two 13, the steel wire hose one 11 and the straight pipe two 9 are fixed by a throat clamp one 10; the steel wire hose one 11 is fixed by a fixing buckle 12.

[0017] Adjust the opening of the ball valve 8 to keep the collecting box 15 at a slight negative pressure. The organic smoke leaked from the fan shaft 3 is sucked into the fan inlet 1 under negative pressure, and the leaked trace condensed liquid is collected by the collecting box 15. Open the ball valve 18 regularly to discharge the condensable liquid. Keep a 2mm gap between the collecting box 15 and the motor shaft 4 to ensure that the collecting box 15 does not rub against the motor shaft 4 and that the amount of gas collected by the fan from the collecting box 15 accounts for a negligible proportion of the overall air volume.

[0018] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, shall be covered by the protection scope of the utility model.
