Abstract
The utility model relates to a rotary scraper knife type machine for preventing or clearing the clogging in a run coal bin, which is provided with a cone-shaped hopper, wherein a gear ring is arranged in the middle of the cone-shaped hopper, and a scraper knife is fixedly connected on the gear ring; a bearing ring is arranged on the outer wall of the cone-shaped hopper under the gear ring; and a rotary support and a guide mechanism are arranged between the bearing ring and the gear ring. In the machine provided by the utility model, the rotation of the hopper and the fixation to the scraper knife in the prior art are changed into the rotation of the scraper knife and the fixation to the hopper, so that the bearing weight of the gear ring is greatly reduced, the driving force is lowered, and the energy is saved. Just owing to the reduction of the bearing weight of the gear ring, the rotary support and the guide mechanism are simplified, namely, a bearing-type rolling structure is adopted, not only the rotary support and the guide mechanism are integrated into one, but also lots of fixing structures are omitted, the structure is simple, and the installation and the maintenance are convenient. The utility model further has the advantages of good sealing property, reliable working, and convenience in installation and maintenance.
Description
Technical field
The utility model relates to a kind of anti-blocking cleaner of coal bunker of thermal powerplant unit pulverized-coal system configuration, the anti-blocking cleaner of particularly a kind of run coal bin rotation perching knife formula.
Background technology
In prior art, Chinese patent ZL200820147790.6 provides a kind of " rotary wall type anti-clogging material warehouse, and public use at home.This material bin comprises a broach hopper, on the outer wall of broach hopper, connect firmly a gear ring, drive the gear ring rotation by motor via reducer, thereby driving broach hopper rotates, on the fixation wall of broach hopper upper/lower terminal, be fixed with a plurality of broken arch block clearing blades, they can be when broach hopper rotates with the material sliding trackle of its inwall, thereby play anti-blocking and the block clearing effect.There is following shortcoming in this patent:
1, owing to the material of hopper inwall adhesion, when particularly stopping up, the weight of hopper is bigger, make the supporting power of gear ring bigger, therefore, promoting the gear ring rotation needs bigger power, not only energy consumption is big, and the guiding mechanism of the swivel bearing of gear ring bottom and hopper rotation is also comparatively huge and complicated.As: in order to possess bigger gear ring swivel bearing power, its supporting structure adopts a plurality of steel wheels of circumferentially evenly arranging that are located on the support ring, and the steel wheel volume is bigger; And for example: hopper rotary steering structure is taken turns with the bigger radially top of volume, and upper and lower two covers are set, and radially wobbles when rotating to prevent hopper, makes structure loaded down with trivial details.
2, sealing property is relatively poor, as shown in Figure 4, subject matter is its sealing surface and vertical setting of trim ring 200 seal faces with labyrinth seal 100, and screw 300,400 plays the fixedly effect of the close circle 100 in labyrinth and trim ring 200, fail sealing surface is formed positive thrust, therefore, it is serious to leak material, pollutes operating environment.
The utility model content
The purpose of this utility model is in order to overcome the deficiency in the prior art, provides a kind of run coal bin rotation perching knife formula anti-blocking cleaner, thereby simplified structure, cuts down the consumption of energy, improves sealing property.
For achieving the above object, the technical solution of the utility model is as follows:
It has a broach hopper, it improves structure: this broach hopper is made up of epimere hopper and two parts of hypomere hopper, between epimere hopper and hypomere hopper, be provided with a gear ring, the coupling end internal diameter of the endoporus of this gear ring and epimere hopper and hypomere hopper matches, and be provided with hermetically-sealed construction between gear ring and epimere hopper and the hypomere hopper, on described gear ring inner hole wall, be fixedly connected with a perching knife, on the broach hopper outer wall below the described gear ring, be provided with a support ring, between this support ring and gear ring, be provided with the swivel bearing and the guiding mechanism of gear ring, on the outer wall of this broach hopper, also be provided with support, on this support, be provided with and gear ring ingear driving gear and deceleration mechanism thereof.
The further improved technical scheme of the utility model is as follows:
The swivel bearing of described gear ring and guiding mechanism are made of the bearing-type rolling structure that is located between gear ring and the support ring.
Described hermetically-sealed construction is by labyrinth seal, trim ring and the push bolt that is installed on this trim ring constitute, the sealing surface of described labyrinth seal is buckled on the gear ring end face, and the perpendicular end surface of its inner ring is a wedge-type inclined-plane, this wedge-type inclined-plane matches with the inclined-plane of broach hopper outer wall, on described wedge-type inclined-plane, be provided with the mounting groove of an O-ring seals and be located at O-ring seals in this mounting groove, on the sealing surface of labyrinth seal, be provided with labyrinth packing groove and gasket structure, described trim ring is fixedly on the outer wall of broach hopper, and be positioned at the back side of labyrinth seal sealing surface, by the push bolt on the precession trim ring labyrinth seal is implemented sealing and compress.
By technique scheme as can be seen, the utility model changes over fixedly with hopper rotation in the prior art, perching knife that perching knife rotates and hopper is fixed, thereby reduced the supporting power (only bearing the weight of perching knife) of gear ring greatly, propulsive effort is reduced, reached purpose of energy saving.Just because of reducing of gear ring supporting power, also make gear ring swivel bearing and guiding mechanism realize simplification, promptly adopted a bearing-type rolling structure, not only make the two unification of swivel bearing and guiding mechanism, also removed many fixed sturctures, make simple in structure, install and maintenance all very convenient.The structure that hermetically-sealed construction of the present utility model has adopted the dynamic seal of the static seal of O-ring seals and labyrinth packing bar to combine, and provided the sealing compressing structure, make sealing effectiveness be better than prior art greatly.Therefore, the utlity model has simple in structure, energy-conservation, good seal performance, reliable operation, installation and advantage such as easy to maintenance.
