Description
Technical field
The present invention relates to oil circulation lubrication system, specifically the bearing lubrication cooling system of the biological shaped granule machine of vertical type ring mould.
Background technique
Vertical type ring mould granulator utilizes the solid waste such as cornstalk, wheat straw, straw, peanut shell, corncob, cotton stem, soybean bar, weeds, branch, leaf, sawdust, bark of crops to be raw material, through pulverizing, pressurization, density, shaping, become little bar-shaped solid particle fuel.Novel bioenergy, it can replace firewood, raw coal, fuel oil, liquid gas etc., is widely used in heating, life cooking stove, water-heating boiler, industrial boiler, biomass power plant etc.It is a kind of living beings new energy materials of high-quality.In granulation process, pressure roller is the core work parts of ring die pelleter, is made up of parts such as pressure roller shell, accentric support axle, bearing, Sealings.During work, accentric support axle is fixed, and pressure roller shell rotates, and pressing materials, make material form particle by the nib of mould.
Forming process middle (center) bearing needs lubrication, and to reduce frictional force and the temperature of bearing, initial vertical type ring mould granulator adopts grease to adopt grease lubrication, needs to carry out timing and refuels.Due in working procedure during compressed granulate, the parts such as pressure roller shell produce heat owing to externally doing work, be in the condition of high temperature in above-mentioned component working process, and the grease in bearing is volatile and produce grease incrustation, makes bearing can not get effectively lubricating, thus damages bearing.
For making bearing lubrication reach good effect, it is the feasible choice of technology that machine oil replaces grease to carry out circulating lubrication.
The Chinese patent of application publication number CN 103388627 A discloses a kind of cooling and lubricating system of biological shaped granule machine, the external filler opening of granulator internal oil passages is located on bearing support by this system, seal with rotary oil seal between bearing support and main shaft, main shaft is connected with pinch roller supporting base transition plate, enclose with O shape between pinch roller supporting base and pinch roller and seal, then be connected with outside oil supplying device respectively with external filler opening by picking out hydraulic fluid port; Normal temperature fluid oil in the fuel tank of outside oil supplying device is supplied to the lubricating oil path of granulator inside through being pumped to external filler opening; after the lubricating oil path of granulator inside, oil return is to cooler; be back to hydraulic station fuel tank again after cooling, form cool cycles lubricating loop.
Technique scheme adopts machine oil to replace grease lubrication, lubricating oil path adopts the intermediate oil inlet mode from bearing support to main shaft to pinch roller supporting base to pinch roller, lubricant oil is transported to bearing support from the oil pipe of outside oil supplying device, main shaft is transported to through bearing support, be transported to pinch roller supporting base through main shaft, be transported in pinch roller through pinch roller supporting base, reach the object of lubrication pressure wheel bearing, pinch roller bearing is lubricated, has certain effect.
Also there is following technical problem topic simultaneously and be difficult to overcome in technique scheme:
1, above-mentioned lubrication only carries out circulating lubrication for pinch roller bearing, does not lubricate for the upper bearing (metal) between main shaft and casing, lower bearing, and the bearing of main shaft can not get synchronous lubrication, and the whole structure of lubrication is poor.
2, pick out hydraulic fluid port and external filler opening is disposed adjacent on bearing support, seal with rotary oil seal between bearing support and main shaft; Sealing effect is poor, easily causes lubricant oil to run off, and cannot carry out effectively lubricating to pinch roller bearing.
3, in main shaft, in the vertical direction is provided with the up lubricating oil path of lubricant oil simultaneously, descending lubricating oil path and simultaneously also will being provided with in the horizontal direction to be connected with external filler opening the lubricating oil path passed through with the hydraulic fluid port that picks out on bearing support, main shaft is due at work will relative to bearing support High Rotation Speed, and the jointing that main shaft is connected with bearing support seals very difficult; And the problems referred to above are present between the lubricating oil path of spindle top main shaft and pinch roller supporting base equally; Lubricant oil very easily overflows along the sidewall of main shaft and supporting base or main shaft and pinch roller supporting base at above-mentioned jointing, makes the circulating lubrication of lubricating oil path ineffective.
4, the design of whole lubricating oil path makes the processing of the oil circuit of main shaft very difficult, even if process above-mentioned main shaft, also can affect the torsional property of main shaft owing to being provided with above-mentioned oil circuit in main shaft; Practical application effect also can be affected.
5, use O shape to enclose between pinch roller supporting base and pinch roller to seal, because O RunddichtringO is mainly used in static seal and reciprocating movement sealing; When it is for rotary movement seal, be only limitted to low speed rotary sealing; Therefore the sealing of O shape circle is difficult to the sealing effect of the machine oil ensureing pressurizing circulation in lubricating oil path.
6, the circulation route of whole lubricating oil path is from down to up, more from top to bottom, the design comparison of circulating oil path is complicated.
