Description
Technical field
The utility model relates to a kind of bottom supporting device of pressed boiler.
Background technique
Pressed boiler is the main equipment of digestion series in aluminium oxide engineering, the features of pressed boiler is high pressure (slip maximum pressure is 5.2 MPa), (slip maximum temperature is 260 ℃ to high temperature, steam maximum temperature is 290 ℃), wherein have stirring shaft drift angle rotation in pressed boiler that reaches 16 ~ 17 meters, the beat amount of stirring shaft lower end is controlled by bottom supporting device.Although the rotational speed of stirring shaft is lower, turn 1 and turn approximately every 3 second, but bearing the high temperature of approximately 260 ° of C, simultaneously with the abrasion of alkaline slurry liquid and the spin friction of equipment and shock, bearing the contact stress of larger load, severe working condition requires base bearing will have higher intensity and surface hardness, high temperature resistant, wear-resistant, corrosion-resistant; Existing bottom supporting device comprises mandrel and the axle sleeve that is Spielpassung, and axle sleeve is connected with stirring shaft, and mandrel is fixed on groove pot bottom, and for meeting operating mode, mandrel and axle sleeve are high hard material; But thus, not only be difficult to processing, during also due to use, there is impulsive load, the fragility of high hard material is larger, this structure generally can only need to more renew with just heavy wear or the damage of 80 days (two manufacture cycles) left and right, causes frequent stop production to overhaul, both increase cost of production, also reduced manufacturing efficiency.
Model utility content
The purpose of this utility model is for prior art above shortcomings, and a kind of Combined bottom bearing device of pressed boiler is provided, and it has advantages of is convenient to processing, long service life, can reduce repair rate, has reduced cost of production, has improved manufacturing efficiency.
For achieving the above object, the Combined bottom bearing device of pressed boiler of the present utility model, comprise mandrel and axle sleeve, it is characterized in that axle sleeve comprises by the connected inner sleeve of drive fit and overcoat, mandrel comprises spindle nose and lining, spindle nose is provided with step, lining is placed on outside the step of spindle nose, one end at spindle nose is installed with pressing plate by Cock screw, pressing plate is close to an end face of lining, and the step surface of spindle nose is close in the other end of lining, and lining and spindle nose are Spielpassung, on the spindle nose excircle adjacent with lining, be provided with several annular grooves, in annular groove, be equipped with seal ring; Lining is placed in inner sleeve and is Spielpassung; Described lining and inner sleeve are high hard material, and overcoat and spindle nose are low hard material;
Mandrel of the present utility model and axle sleeve all adopt composite structure, and its fitting surface is high hard material, can meet the demand of intensity and hardness, have improved toughness simultaneously, are convenient to again processing; Lining and spindle nose are Spielpassung and between the two, are provided with flexible seal ring, when producing impulsive load between mandrel and axle sleeve, can play buffer function, avoid damaging, can increase the service life, reduce repair rate, reduce cost of production, improved manufacturing efficiency;
As further improvement of the utility model, describedly outer be arranged with shoulder hole, be inside placed in the macropore of shoulder hole; Be convenient to the connection and positioning of inner sleeve and overcoat;
In sum, the utlity model has the advantage of being convenient to processing, long service life, can reduce repair rate, reduced cost of production, improved manufacturing efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's plan view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the Combined bottom bearing device of this pressed boiler, comprises mandrel 1 and axle sleeve 2, and axle sleeve 2 comprises that overcoat 4 is provided with shoulder hole by the connected inner sleeve 3 of drive fit and overcoat 4, and inner sleeve 3 is placed in the macropore of shoulder hole; Mandrel 1 comprises spindle nose 5 and lining 6, spindle nose 5 is provided with step, lining 6 is placed on outside the step of spindle nose 5, one end at spindle nose 5 is installed with pressing plate 8 by Cock screw 7, pressing plate 8 is close to an end face of lining 6, and the step surface of spindle nose 5 is close in the other end of lining 6, and lining 6 is Spielpassung with spindle nose 5, on spindle nose 5 excircle adjacent with lining 6, be provided with several annular grooves, in annular groove, be equipped with O RunddichtringO 9; Lining 6 is placed in inner sleeve 3 and is Spielpassung; Described lining 6 is high hard material with inner sleeve 3, and as manganese evanohm, overcoat 4 and spindle nose 5 are low hard material, as carbon steel or stainless steel;
Mandrel 1 of the present utility model and axle sleeve 2 all adopt composite structure, and its fitting surface is high hard material, can meet the demand of intensity and hardness, and other parts are low hard material, have improved toughness, are convenient to again processing; Lining 6 and spindle nose 5 are little Spielpassung and between the two, are provided with flexible quality of rubber materials O RunddichtringO 9, when producing impulsive load between mandrel 1 and axle sleeve 2, seal ring 9 can play buffer function, avoid damaging, can increase the service life, more than extending to four manufacture cycles (180 days) by two former manufacture cycles, reduce repair rate, reduce cost of production, improved manufacturing efficiency.
