Description
Technical field
The utility model relates to raymond mills, and in particular to the air-tight structure of grinding roll of Raymond mill axis.
Background technique
Raymond mill is one of widest equipment of nonmetallic mineral processed and applied.Grinding roller is most heavy in raymond mill
The component wanted, grinding roller revolves in bull ring generates centrifugal force comminuting matter and the rotation under frictional force effect.Support shaft of grinding roller
Bearing is divide into upper part and lower part, and upper bearing farther out from disintegrating area, is hardly damaged, and lower bearing is due to closer from disintegrating area,
Dust is full of in running environment, and more serious by vibration influence, dust, which is easily accessible in bearing, causes bearing damage, leads to equipment
Maintenance frequently, increases production cost and reduces production efficiency.
Summary of the invention
The utility model provides a kind of air-tight structure of grinding roll of Raymond mill axis, blocks dust to enter mill using clean air
The lower bearing of roll shaft, the lower bearing to solve the problems, such as shaft of grinding roller are easy to damage.
In order to solve the above technical problems, the utility model provides a kind of hermetic seal of such as grinding roll of Raymond mill axis of flowering structure
Structure, including pedestal connect collar bush on the base, and main shaft is rotatably connected in collar bush, mill is fixed at the top of main shaft
Roller support frame is hinged on grinding roller support frame in grinding roller axle sleeve, grinding roller axle sleeve and is rotatably connected to shaft of grinding roller, shaft of grinding roller by bearing
On be set with below grinding roller axle sleeve and be connected to shaft of grinding roller and cover upper bearing gland；Its design feature is: the grinding roller
It is set on axis and is connected to shaft of grinding roller and puts on or be connected to air chamber cover on bearing gland, gas chamber is equipped in air chamber cover, into gas
Indoor air can gap between air chamber cover and shaft of grinding roller blow out to prevent dust from entering bearing；The grinding roller support frame and
Air cavity is formed between collar bush, air-tight structure further includes air inlet pipe, and the air inlet pipe is connected to air cavity, air cavity by hose with
The gas chamber connection.
It is set with fixed cylinder on the collar bush, is connected with sealing shroud on grinding roller support frame, the sealing shroud lower end and solid
The upper end sleeve of safety barrel forms sealing matching relationship together and between sealing shroud and fixed cylinder；The grinding roller support frame, sealing
Set, fixed cylinder and collar bush surround the air cavity.
The air inlet pipe is connected in fixed cylinder, and one end of the hose is connected on grinding roller support frame, the other end connects
On air chamber cover.
The sealing ring being sleeved on shaft of grinding roller is equipped between the air chamber cover and bearing gland.
When Raymond mill works, air inlet pipe is connected to feeder, air enters air cavity and enters gas chamber by hose again,
Into gas chamber air can gap between air chamber cover and shaft of grinding roller blow out, under the blocking of air-flow, dust hardly enters axis
In holding, thus the abrasion of bearing can be reduced, the service life of bearing can be greatly prolonged and reduce the maintenance of equipment frequency, reduce production
Cost and improve production efficiency.In addition, the utility model by between grinding roller support frame and collar bush formed air cavity and
By the setting of the air chamber cover equipped with gas chamber, goal of the invention can be achieved with, thus have the advantages that structure is simple.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the utility model；
