Abstract
The utility model provides an adjustable stirring tooth structure of the wet granulating machine. The stirring tooth of the prior wet granulating machine is fixedly welded on a shaft pipe of a rotary shaft, being a mounting structure which is not adjustable and satisfied in producing precision and using maintenance. One end of the stirring tooth of the utility model is changed into a screw sleeved with a screw sleeve; in stead of directly welding the stirring tooth on the shaft pipe of the rotary shaft, the screw sleeve is welded on the shaft pipe, and the stirring tooth is orderly connected by use of a reinforcing steel bar. When in product making and using maintenance, by adjusting the screw, the requirement of consistent rotary radius of the stirring tooth is achieved, canceling the surface machining of the shaft pipe of the rotary shaft and the surfacing technology with extremely large difficult.
Description
The utility model relates to the mount fixing structure that a kind of wet granulator stirs tooth.
Stir the same employing of installing and fixing of tooth on the at present domestic and international wet granulator rotating shaft central siphon and directly be welded on the rotating shaft central siphon, become uncontrollable mount fixing structure stirring tooth.Fig. 1 is the typical case of this structure.(1) is to stir tooth among the figure, and (2) are the rotating shaft central siphons, and (3) are stiffeners.Some round bar shapes stir tooth (1) and arrange and be welded on the rotating shaft central siphon (2) by helix, in order to strengthen stirring the bending resistance of tooth, are subjected to the force direction stiffener (3) of burn-oning along stirring tooth.This structure is continued to use for many years, though be feasible on producing, all very inconvenient at aspects such as installation and maintenances.At first aspect installation, require rotating shaft to stir top radius of turn unanimity when rotating shaft is rotated of tooth, but adopt this old installation and fixed structure, be difficult to reach this requirement, also rotating shaft central siphon outer surface also must carry out axiality processing, increased manufacturing cost.Secondly aspect maintenance, because stirring the main abrading section of tooth is the tooth top of overhanging end, when tooth top wearing and tearing 3-5 millimeter, just must keep in repair, the conventional approach of maintenance is to carry out the built-up welding of identical material stirring tooth top portion defect, but have nearly one, 200 to stir tooth in rotating shaft long about 3 meters, workload is big well imagines.In addition, the bead-welding technology difficulty is big, is difficult to reach quality requirement, more need not look to stirring after the built-up welding tooth top portion radius of turn and reach consistent.
Task of the present utility model provides a kind ofly stirs the new construction that tooth installs and fixes, so that overcome above-mentioned shortcoming.
The utility model is mainly conceived as follows: allow each root stir tooth and all use with the rotating shaft central siphon and be threaded, so that install and regulate during maintenance; All teeth that stirs are linked in sequence stirring on the middle part height of tooth with a reinforcing bar, strengthen the bending resistance of stirring tooth, remove the trouble of stirring welding stiffener on the tooth at each root from.
Fig. 2 is the embodiment of this design, and (2) are the rotating shaft central siphons among the figure, and (4) are to stir tooth, and (5) are nut sleeve, and (6) are reinforcing bars.An end that stirs tooth (4) is a screw thread, nut sleeve (5) is being overlapped in the screw thread outside, nut sleeve position on request is welded on the rotating shaft central siphon (2), for the bending resistance of strengthening stirring tooth is stirred tooth to all and is linked in sequence stirring tooth middle part height with a reinforcing bar (6), the method for connection as A-A analyses and observe on the top of reinforcing bar and stir tooth spot welding.During maintenance solder joint is cut spot welding again after the length of the requirement of back-outing.
The utility model has the advantages that: 1. when product is made, can stir tooth by each root of fine adjustment Radius of turn, improved the precision that product is installed; 2. in when maintenance, as long as needing repairing The solder joint that stirs on the tooth cuts, and just can regulate arbitrarily, and wearing and tearing how much, just what accesses, and works as adjusting Measure directly to change when inadequate and stir tooth, removed the very big bead-welding technology of difficulty from, greatly reduced dimension Repair workload, and improve the installation accuracy after the maintenance. 3. all teeth that stir are with a reinforcing bar spot welding Be connected, both reached and strengthen the bending resistance that each root stirs tooth, removed from again at each root and having stirred The trouble of welding stiffener on the tooth. 4. be adjustable structure because stirring tooth, rotating shaft central siphon outer surface need not advance The processing of row axiality has reduced manufacturing cost.
Claims (1)
- Wet granulator is adjustable, and to stir toothing be to by the rotating shaft central siphon.Stir a kind of improvement of the wet granulator that tooth etc. forms; it is characterized in that: an end that stirs tooth is a screw thread; nut sleeve (5) is being overlapped in screw thread outside, and nut sleeve is welded on the rotating shaft central siphon (2), highly use at the middle part of stirring tooth a reinforcing bar (6) each root stir tooth in order spot welding connect as one.
