Description
Technical Field
The utility model relates to a scraper machine, in particular to a sealed rotary scraper machine.
Background
The existing bulk cargo is discharged, the bottom of the bin is generally a cone, and the bin cone occupies a large amount of equipment space for ensuring a sliding angle, so that the manufacturing cost of a factory building is greatly increased, and the process cost is greatly increased.
The sealed rotary scraper machine is widely applied to the thermal power industry, the metallurgical industry, the environmental protection industry and the chemical industry. For example, the dust collection and transportation of flue dust in thermal power and metallurgical industry, the collection and transportation of biomass particles in environmental protection industry and the collection and transportation of materials with poor fluidity in chemical industry. The sealed rotary scraper adopts a flat bottom bin discharging mode, so that equipment arrangement space is greatly saved, process cost is reduced, no leakage is realized, and the environment is protected and safety is realized. But the device is applied to a small number of bulk bins.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a sealed rotary scraper machine, which can save a certain space compared with the existing cone discharge port, has good sealing performance, can enable equipment to work for a long time and has low failure rate.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a sealing rotary scraper machine comprises a bin body, wherein a scraper assembly is arranged in the bin body and comprises a scraper supporting frame arranged on a driving shaft, and a plurality of groups of detachable scrapers are circumferentially arranged on the scraper supporting frame; the bottom outside the bin body is provided with a mounting fixing seat, a gear motor is mounted on the mounting fixing seat, and the output end of the gear motor is connected with a driving shaft; the outer ring of the upper part of the driving shaft is provided with a sealing box; the lower part of the driving shaft is rotatably connected with the installation fixing seat through a plane bearing.
And the detachable scraper is coated with a wear-resistant alloy, and a wear-resistant plate is welded at the end part of the detachable scraper.
The upper end of the scraper supporting frame is provided with a conical decompression cover through bolts.
The utility model discloses a sealing rotary scraper machine, which has the following technical effects:
1) The sealing box adopts a sealing mode of primary packing sealing and secondary frameless oil sealing, so that ash leakage is prevented, and the service life of the bearing is not affected due to the fact that ash particles fall into the bearing.
2) The plane bearing supporting scraper assembly is arranged in the equipment to flexibly rotate, so that the equipment works for a long time, and the failure rate is low. The inner sleeve and the outer sleeve of the plane bearing only slide linearly, and the plane bearing does not rotate through rolling bodies such as rolling balls or rollers like a common bearing. The plane bearing rotates steadily, and bearing capacity is strong, and holding power is even, and frictional force is little.
3) The decompression cover can decompose the pressure of ash particles in the bin to the scraper assembly; the running resistance of the equipment is reduced, so that the energy consumption is reduced.
4) The detachable scraper is fastened on the scraper supporting frame through bolts, and the scraper is convenient to detach and replace; meanwhile, the scraper is coated with the wear-resistant alloy, and the end part is welded with the wear-resistant plate, so that the wear resistance can be improved.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is a top view of the present utility model.
In the figure: the automatic scraper device comprises a bin body 1, a decompression cover 2, a scraper assembly 3, a sealing box 4, a mounting fixing seat 5, a plane bearing 6, a gear motor 7, a driving shaft 8, a scraper supporting frame 9, a detachable scraper 10, a wear-resisting plate 11 and an outlet 12.
Detailed Description
As shown in fig. 1-2, a sealed rotary scraper comprises a bin body 1, wherein the upper end of the bin body 1 is fixed at the bottom of the device through a flange at the edge. The scraper assembly 3 is arranged in the bin body 1, the scraper assembly 3 comprises a scraper supporting frame 9 arranged on the driving shaft 8, the detachable scraper 10 is connected to the scraper supporting frame 9 through bolts, and the detachable scraper 10 is uniformly distributed around the axis of the driving shaft 8 in groups. The bottom of the bin body 1 is provided with a mounting fixing seat 5, a gear motor 7 is connected with the mounting fixing seat 5 through a flange, and the output end of the gear motor 7 is connected with a driving shaft 8. The driving shaft 8 is rotatably connected with the lower end part of the installation fixing seat 5 through the plane bearing 6. The outer ring of the upper part of the driving shaft 8 is provided with a sealing box 4, and the sealing box 4 is arranged on the bin wall through bolts.
Preferably, the sealing box 4 is internally provided with a primary packing seal and a secondary frameless oil seal, so that leakage of ash can be prevented, and the ash particles are prevented from falling into the plane bearing 6 to influence the service life of the bearing.
Preferably, the detachable scraper 10 is coated with a wear-resistant alloy, and the end part is welded with a wear-resistant plate 11. Therefore, the wear resistance can be improved, and the long-term use is ensured.
Preferably, the decompression cover 2 is fastened on the scraper supporting frame 9 through bolts, the decompression cover 2 can decompose the pressure of ash particles on the scraper assembly 3, and the running resistance of equipment is reduced, so that the energy consumption is reduced.
Preferably, the installation fixing seat 5 is provided with an access hole, so that packing can be conveniently pressed, and wearing parts such as an oil seal, a bearing and the like can be replaced.
Working principle and process: the ash particles fall into the bin body 1, and the gear motor 7 drives the driving shaft 8 to rotate, and the driving shaft 8 drives the scraper assembly 3 to rotate. The detachable scraper 10 conveys the dust particles out of the discharge opening to finish discharging. The ash powder particles can be used as roadbed filler of highways, brick making and the like.
