Description
Technical field
This utility model belongs to roll squeezer, roller mill field, particularly relates to a kind of roll squeezer main shaft sealing device.
Background technology
Roll squeezer is a kind of efficient, energy-conservation milling equipment, is widely used in cement, metallurgy, Ore industry. What the end face seal of conventional roll press bearing block bearing and roll squeezer main shaft adopted is that lip-shaped sealed ring is directly installed on main shaft, or the form that lip-shaped sealed ring and V-type end face seal carry out arranging in pairs or groups seals, but owing to not forming pressure differential with the external world in annular seal space, along with roll squeezer runs for a long time, there is abrasion in sealing ring, within causing that dust enters sealing ring, cause abrasion and the damage of roll shaft or bearing.
Utility model content
The purpose of this utility model is in that: propose a kind of for the air seal set between roll squeezer bearing block bearing and roll squeezer main shaft, reduces the entrance of various foreign material, improves bearing life.
The purpose of this utility model is realized by following technical proposals:
A kind of for the air seal set between roll squeezer bearing block bearing and roll squeezer main shaft, including roll squeezer bearing block bearing and roll squeezer main shaft, it is provided with the sealing ring of end face seal between the two, also include sealing gland cover plate and sealing plate, semitight region is formed between sealing gland cover plate and sealing plate and sealing ring, sealing gland cover plate is communicated with the air inlet in this semitight region, sealing plate and leave gap between main shaft and form vent air gap.
As selection, sealing gland cover plate outer ring is secured by bolts in bearing block transparent cover, and inner ring is bolted sealing plate.
As selection, sealing gland cover plate is provided with cannelure, and air inlet is opened in cannelure, and by the semitight region between this cannelure connection sealing gland cover plate and sealing plate and sealing ring.
As selection, sealing ring is V-type end face seal.
As selection, air inlet number is the integer of 2. The air inlet perforate number of the program is determined by needs, it is possible to have 1 or multiple, controls admission pressure by controlling air inlet, and general perforate number is the integer of 2.
Aforementioned this utility model main formula case and each further selection scheme thereof can independent assortment to form multiple scheme; it is the scheme that this utility model can adopt and claim: such as this utility model; each selection can select with other; those skilled in the art can understand there is multiple combination according to prior art and known general knowledge after understanding the present invention program; it is the claimed technical scheme of this utility model, does not do exhaustive at this.
Workflow of the present utility model:
The basis of roll squeezer primary seals increases sealing gland cover plate and a sealing plate, and between sealing ring, form certain semitight region, it is inflated to this semitight region by air-filled pore by external inflation device, and by the gap aerofluxus between sealing plate internal diameter and the diameter of axle, the air of discharge is controlled by the gap between the main shaft diameter of axle and sealing plate internal diameter. By inflating, make between sealing gland cover plate, sealing ring and roll squeezer main shaft formed region produce the blowing pressure, this the blowing pressure is more than external air pressure, and the foreign material such as dust, dirt cannot propagate into air seal set interior zone, more will not enter into inside bearing. Thus greatly reduce the entrance of various foreign material, be very helpful to improving bearing life.
The beneficial effects of the utility model: greatly reduce the entrance of various foreign material, significantly improve bearing life.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of this utility model embodiment;
Fig. 2 is the schematic front view of this utility model embodiment;
In figure, 1 is roll squeezer main shaft, and 2 is V-type end face seal, and 3 is sealing gland cover plate, and 4 is sealing plate, and 5 is air inlet, and 6 is gap, and 7 is bolt, and 8 is bearing block transparent cover, and 9 is cannelure.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further described.
With reference to Fig. 1, shown in 2, a kind of for the air seal set between roll squeezer bearing block bearing and roll squeezer main shaft 1, including roll squeezer bearing block bearing and roll squeezer main shaft 1, it is provided with the sealing ring of end face seal between the two (exemplarily, V-type end face seal 2 as shown in this embodiment), also include sealing gland cover plate 3 and sealing plate 4, semitight region is formed between sealing gland cover plate 3 and sealing plate 4 and V-type end face seal 2, sealing gland cover plate 3 is communicated with the air inlet 5 in this semitight region, leaves gap 6 between sealing plate 4 and main shaft 1 and form vent air gap. Air inlet 5 number is the integer of 2, exemplarily, and 2 as shown in this embodiment. Sealing gland cover plate 3 outer ring is fixed in bearing block transparent cover 8 by bolt 7, and inner ring connects sealing plate 4 by bolt 7. Sealing gland cover plate 3 is provided with cannelure 9, and air inlet 5 is opened in cannelure 9, and connects the semitight region between sealing gland cover plate 3 and sealing plate 4 and V-type end face seal 2 by this cannelure 9.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
