Abstract
The utility model discloses an improved bottom bearing base device for boiler screw slag remover including a screw shaft, the lower part of the screw shaft is sheathed with an upper bearing block, an echelonment inner ring cavity is arranged along the bottom of upper bearing block. The bottom of the screw shaft is provided with a lower bearing block which is corresponding to the upper bearing block and provided with an inner ring cavity. The upper and lower bearing blocks are connected by bolt and an elastic skeleton packing ring as well as a bearing are arranged from top to bottom in the empty cavity between the inner ring cavities of the upper and lower bearing blocks as well as the screw shafts. The utility model divides the bearing base at the bottom of the screw shaft into up-down parts and has the advantages of simple structure as well as convenient installation and maintenance. An elastic skeleton packing ring and a bearing arranged from top to bottom in the empty cavity between the inner ring cavities of the upper and lower bearing blocks and the screw shaft, which makes the bottom of the screw shaft sealed closely, so as to prolong the service life of the whole slag remover.
Description
Technical field
The utility model relates to a kind of boiler spiral tapping machine bottom bearings modifying device.
Background technique
At present, boiler spiral tapping machine bottom relies on the Stuffing box sealing, and the spiral the tip of the axis is provided with independently bearing support, and bearing support is connected with the screw axis cylindrical shell by screw rod.The distinct disadvantage that this structure exists is: owing to contain a large amount of grey solid impurity particles in the cooling water in the slagging machine cylindrical shell, filler and screw axis in the Stuffing box are easy to be worn, difficult sealing is to guarantee, in case seal failure, cooling water can flow in the bearing support of bottom, cause the bearing corrosion, in addition stuck.On the other hand, because filler and screw axis wearing and tearing, sealing can not get guaranteeing that the chilled water in the slagging machine cylindrical shell is difficult to guarantee, causes the helical blade wearing and tearing, the working life of reducing slagging machine.
Summary of the invention
The technical problems to be solved in the utility model provides tight, the long-lived boiler spiral tapping machine bottom bearings modifying device of a kind of screw axis bottom sealing, thus whole working life of improving slagging machine.
For solving the problems of the technologies described above, the utility model comprises screw axis, its structural feature is to be set with upper bearing bracket in the bottom of screw axis, be provided with stepped interior ring cavity along the upper bearing bracket bottom, the bottom of screw axis be equipped with corresponding with upper bearing bracket, have in the step of ring cavity, link together by bolt between the metal (upper seat, elastic skeleton seal ring, bearing are installed in the cavity in the metal (upper seat between ring cavity and the screw axis from top to bottom.
Between screw axis bottom axle head and step inner bottom surface, wear-resisting steel disk is installed.
Described its shaft section of elastic skeleton seal ring is the U type.
After adopting said structure, because the bearing support of screw axis bottom is divided into two-part up and down, it is simple in structure, installation, maintenance is convenient, and in the metal (upper seat, in the cavity between ring cavity and the screw axis elastic skeleton seal ring, bearing are installed from top to bottom, the sealing of screw axis bottom is tight, thus whole working life of improving slagging machine; Between screw axis bottom axle head and step inner bottom surface, wear-resisting steel disk is installed, can prolongs the working life of step.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Accompanying drawing is a cross-sectional view of the present utility model.
Embodiment
With reference to accompanying drawing, this boiler spiral tapping machine bottom bearings modifying device comprises screw axis 1, is set with upper bearing bracket 2 in the bottom of screw axis 1, and upper bearing bracket 2 is the integral solder part, and its top edge and spiral tapping machine cylindrical shell bottom weld together.Be provided with stepped interior ring cavity along upper bearing bracket 2 bottoms, the bottom of screw axis 1 be equipped with corresponding with upper bearing bracket 2, have in the step 6 of ring cavity, link together by bolt 5 between the metal (upper seat, elastic skeleton seal ring 3, bearing 4 are installed in the cavity in the metal (upper seat between ring cavity and the screw axis 1 from top to bottom, between the axial two ends of bearing 4 and metal (upper seat surface of contact, also are provided with the sealing gasket (not shown).Utilize the fastening force of bolt 5 that elastic skeleton seal ring 3, bearing 4 are produced pressure, elastic skeleton seal ring 3 is subjected to the effect of axial force and produces radial deformation, increases sealing effect, and elastic skeleton seal ring 3 its shaft sections are the U type, are made by rubber material; Between screw axis 1 bottom axle head and step 6 inner bottom surfaces wear-resisting steel disk 7 is installed, wear-resisting steel disk 7 thickness can be adjusted, so as reasonably combined with the length of screw axis 1, and the working life of prolongation step.
