Present horizontal cooling mixing machine is generally drum or U type slot type structure, as shown in Figure 1, the mounting structure of main shaft and cylindrical shell in the horizontal cooling mixing machine, comprise: be arranged on supporting construction and hermetically-sealed construction between main shaft 1 and the cylindrical shell 2, described supporting construction comprises: a pair ofly be fixed on bearing block 3 on the cylindrical shell 2 both sides side plates 21 by diagonal brace 9, be provided with bearing 4 in the bearing block 3, described main shaft 1 is located in this in the bearing 4; Described hermetically-sealed construction comprises: a pair of spacer sleeve 5 that is arranged on the main shaft 1, be set with sealing shroud 6 and packing gland 7 on the spacer sleeve 5, and sealing shroud 6 is welded on the corresponding side side plate 21, is provided with packing 8 between spacer sleeve 5 and the sealing shroud 6.The shortcoming of this mounting structure is:
1, since the diagonal brace of installation shaft bearing join and be welded on the cylindrical shell side plate, therefore, in use for some time, diagonal brace is subjected to the influence of welding stress can produce distortion, make the axle center of bearings at both ends be offset, not only shortened the service life of bearing, but also caused main shaft and sealing shroud off-centre, cause the seal uneven wear in the sealing shroud, cause main shaft to leak material.
2, when the dismounting bearing, at first need side plate is pulled down earlier, and then main shaft is got, bearing is stayed in the bearing block, is not easy very much to take out.This just makes main shaft and bearing removal very inconvenient.
The utility model content
A technical problem to be solved in the utility model is: a kind of welding stress, main shaft and bearing removal mounting structure of main shaft and cylindrical shell in the horizontal cooling mixing machine easily that reduces is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the mounting structure of main shaft and cylindrical shell in the horizontal cooling mixing machine, comprise: be arranged on supporting construction and hermetically-sealed construction between main shaft and the cylindrical shell, described supporting construction comprises: a pair ofly be arranged on bearing block on the side plate of cylindrical shell both sides by diagonal brace, be provided with bearing in the bearing block, described main shaft is located in this in the bearing; Described hermetically-sealed construction comprises: a pair of spacer sleeve that is arranged on the main shaft, be set with sealing shroud and packing gland on the spacer sleeve, be provided with packing between spacer sleeve and the sealing shroud, each diagonal brace is locked on the side plate of a corresponding side by mount pad and the mounting seat that cooperatively interacts, each sealing shroud is located in the side plate of a corresponding side, the outer wall of sealing shroud is provided with the connection boss, and each mounting seat is provided with the connection groove, connects boss and is locked in the connection groove of a corresponding side.
Be provided with outside framework oil seal between each bearing block and the spacer sleeve, the arranged outside of each bearing block has bearing cap, is provided with sealing ring between each bearing cap and the main shaft, and the arranged outside of bearing cap has gland.
The beneficial effects of the utility model are: the utility model is by being welded on mounting seat in advance on the side plate of cylindrical shell, bearing block passes through the diagonal brace predetermined fixed on mount pad, when assembling, be fixed on bearing block on the side plate of cylindrical shell by mount pad and mounting seat, just greatly reduce welding stress, and dismounting need not be dismantled side plate during bearing; In addition,, make when the dismounting main shaft, need not dismantle side plate equally by changing the structure of sealing shroud.So just make the dismounting of main shaft and bearing become very simple, thereby greatly facilitate daily maintenance and maintenance.
