Description
Technical field
The present invention relates to one material chamber sealing ring, particularly a kind of vane type wet-spraying machine of turning to turn material cavity sealing structure.
Background technology
Existing vane type pulp shooting machine mainly can be divided on air intake structure to turn side air inlet and from central axis air inlet from impeller.Tradition is from the vane type pulp shooting machine of side air inlet of turning, because airintake direction is different from the direction of discharging, often cause spray pressure not enough, and have a large amount of cement pastes to remain in bottom and the material side, chamber in material chamber, whitewashing efficiency is low, and the workload of rear cleaning of having whitewashed is large.And tradition is from the vane type pulp shooting machine of central axis air inlet, turning with hollow shaft due to vane type is be rotationally connected, and between the two often without sealing ring or only use O shape circle, sealing effectiveness is poor, gas often overflows bottom material chamber, causes spray pressure not enough.Even there is minority cement paste also can enter bearing bottom material chamber, thus damage bearing, serious curtailment application life of machine.
Summary of the invention
For the defect that prior art exists, the utility model provides a kind of vane type wet-spraying machine and to turn material cavity sealing structure, greatly can improve impeller and turn and sealing between hollow jackshaft.
Concrete technical scheme is: a kind of vane type wet-spraying machine is turned material cavity sealing structure, comprise impeller to turn, fixed cavity, hollow jackshaft, impeller fixed cover of turning is located on hollow jackshaft, hollow jackshaft is provided with venthole, fixed cavity is along impeller full twist to setting, described impeller is turned and is provided with protection steel bushing between hollow jackshaft, protection steel bushing to be fixedly installed on hollow jackshaft and protection steel bushing is provided with the air outlet corresponding with hollow jackshaft venthole, protection steel bushing two ends are arranged with sleeve, sealing device is provided with between sleeve and protection steel bushing, sleeve inner side end is provided with potted component, potted component is sheathed on protection steel bushing, the lateral surface of potted component medial extremity is provided with the first groove of lower end male cooperation of turning with impeller, potted component to be turned axial location by sleeve and impeller.
Described sleeve inner side end is provided with the second groove, and the second groove is at sleeve inner side end and sleeve medial surface opening, and potted component outboard end is arranged in the second groove.
Described protection steel bushing and impeller are turned matched in clearance.
Described sealing device is O type circle.
Described sleeve medial surface is provided with the 3rd groove, and O type circle is arranged in the 3rd groove.
Described protection steel bushing one end circumference is provided with the boss extended to its end face center of circle, and protection steel bushing is connected with hollow jackshaft by the bolt be arranged on boss.
The utility model structure is simple, and cost is low, relative to traditional vane type pulp shooting machine, has added protection steel bushing at the impeller center of turning, and protecting rotor can not wear and tear in reciprocating rotary.Meanwhile, bottom the material chamber that impeller is turned and protection steel bushing add potted component between this, effectively can compensate for the gap between both, ensure that enough spray pressures.Meanwhile, can prevent cement paste from entering inside bearing from this gap, effective protection has been carried out to bearing.

Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of vane type wet-spraying machine is turned material cavity sealing structure, comprise impeller and turn 1, fixed cavity 2, hollow jackshaft 3, impeller 1 fixed cover of turning is located on hollow jackshaft 3, hollow jackshaft 3 is provided with venthole, fixed cavity 2 along impeller turn 1 circumference arrange, impeller is turned between 1 and hollow jackshaft 3 and is provided with protection steel bushing 4, protection steel bushing 4 and impeller are turned 1 matched in clearance, protection steel bushing 4 to be fixedly installed on hollow jackshaft 3 and protection steel bushing 4 is provided with the air outlet 5 corresponding with hollow jackshaft 3 venthole, as Fig. 4, shown in Fig. 5 and Fig. 6, protection steel bushing 4 two ends are arranged with sleeve 6, sealing device 7 is provided with between sleeve 6 and protection steel bushing 4, sealing device 7 is O type circle, sleeve 6 medial surface is provided with the 3rd groove 11, O type circle is arranged in the 3rd groove 11, sleeve 6 inner side end is provided with potted component 8, potted component 8 is sheathed on protection steel bushing 4, the lateral surface of potted component 8 medial extremity is provided with the first groove 9 of 1 lower end male cooperation of turning with impeller, potted component 8 to be turned 1 axial location by sleeve 6 and impeller, sleeve 6 inner side end is provided with the second groove 10, second groove 10 is at sleeve 6 inner side end and sleeve 6 medial surface opening, potted component 8 outboard end is arranged in the second groove 10, potted component 8 sleeve 6 and impeller turn 1 effect under be close to protection steel bushing 4 surface, thus make impeller turn 1 and protection steel bushing 4 between there is good sealing, O type circle is defined position in the 3rd groove 11, when potted component 8 is after long-time wearing and tearing tightness declines, O type circle can strengthen the tightness that impeller is turned between 1 and protection steel bushing 4 further, prevent gas leak phenomenon from occurring.
Protection steel bushing 4 one end circumference is provided with the boss 12 extended to its end face center of circle, and protection steel bushing 4 is connected with hollow jackshaft 3 by the bolt be arranged on boss 12, installation for convenience detach.
