Abstract
The utility model discloses an exhaust dust prevention device of a vertical shaft crusher. The exhaust dust prevention device of the vertical shaft crusher comprises a transmission shaft, and a bearing barrel sleeved outside the transmission shaft, wherein the top of the bearing barrel is provided with an upper bearing cap, the side wall of the bearing barrel is provided with an air channel communicated with the top of the bearing cap; a dust prevention cover is sleeved on the transmission shaft above the upper bearing cap, a ring-shaped chamber is formed between the dust prevention cover and the upper bearing cap, and dust prevention blades are fixedly connected at relative positions of the dust prevention cover in the ring-shaped chamber, respectively. The exhaust dust prevention device of vertical shaft crusher has the advantages of simple structure and steady operation; under the premise of increasing no difficulty in equipment manufacturing technology, pressure between the dust prevention cover and the upper bearing cap is increased by the dust prevention blades, dust in the air is kept away from the dust prevention cover, operation stability of the bearing in the bearing barrel is guaranteed, meanwhile, pollution to the lubricating oil caused by dust is prevented, and equipment failure caused by invasion of dust in a transmission system is avoided.
Description
Technical field
The utility model relates to vertical shaft impact crusher, especially relates to a kind of vertical-spindle hammer crusher air draft dust guard.
Background technology
Vertical shaft impact crusher is widely used in metal and nonmetal deposits stone, construction material, man made is husky and fragmentation and the shaping of various metallurgical slags.In the use procedure of current neutral axis disintegrating machine of the same trade, dust is larger, causes sedimentating dust in transmission system, causes driving unit fault and lubricant pollution, for the normal even running of equipment causes larger puzzlement.
Summary of the invention
The utility model purpose is to provide a kind of vertical-spindle hammer crusher air draft dust guard that can prevent dust intrusion transmission system.
For achieving the above object, the utility model can be taked following technical proposals:
Vertical-spindle hammer crusher air draft dust guard described in the utility model, comprise power transmission shaft and the bearing cartridge that is sleeved on described power transmission shaft outside, be provided with upper ball cover at described bearing cartridge top, offer the air duct be connected with described upper ball cover top at described bearing cartridge sidewall; Be set with dust cap on the power transmission shaft be positioned at above upper ball cover, and form an annular compartment between described dust cap and upper ball cover, at the dust cap relative position place that is positioned at described annular compartment, be fixed with respectively dustproof blade.
Be provided with air filter on the air duct air inlet be positioned on described bearing cartridge.
The utility model advantage is simple in structure, stable, do not increasing under device manufacturing process difficulty prerequisite, increased pressure between dust cap and upper ball cover by dustproof blade, airborne dust is blocked in outside dust cap, guarantee the stability of bearing cartridge middle (center) bearing operation, prevented the pollution of dust to lubricating oil simultaneously, avoid dust to invade transmission system and cause equipment fault.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, vertical-spindle hammer crusher air draft dust guard described in the utility model, comprise power transmission shaft 1 and the bearing cartridge 2 that is sleeved on described power transmission shaft 1 outside, be provided with upper ball cover 3 at described bearing cartridge 2 tops, offer the air duct 4 be connected with described upper ball cover 3 tops at described bearing cartridge 2 sidewalls; Be set with dust cap 5 on the power transmission shaft 1 be positioned at above upper ball cover 3, and form an annular compartment between described dust cap 5 and upper ball cover 3, be fixed with respectively dustproof blade 6 at the dust cap 5 relative position places that are positioned at described annular compartment; Be provided with air filter 7 on the air duct air inlet be positioned on described bearing cartridge 2.
Its operation principle is: after power transmission shaft 1 running, dust cap 5 and dustproof blade 6 will be with power transmission shaft 1 rotations, dustproof blade 6 produces air-flow, air between dust cap 5 and upper ball cover 3 is discharged, prevent that outside powder containing quantity from entering than atmospheric, cause dust between dust cap 5 and upper ball cover 3 to stop up, to transmission system bearing influence on system operation and to the pollution of lubricating oil, between dust cap 5 and upper ball cover 3, gas make-up enters by the air duct 4 in bearing cartridge 2 walls, and in order to guarantee the make-up gas cleannes, air duct 4 entry positions outside bearing cartridge 2 install air filter 7 additional, dust in filtered air.
