Technical field
The utility model technology relates to a kind of bearing oil cold type micronizer, be mainly used in feed factory, pulverize various coarse crushing materials such as corn, jowar, rice wheat class, dregs of beans, fishes and shrimps etc., to reach the ultra-fine granularity material of required standard, be specially adapted to the fine micronizer of prawn, soft-shelled turtle, eel and brood feed.
Background technology
Micronizer is mainly used in feed factory, pulverize various coarse crushing materials such as corn, jowar, rice wheat class, dregs of beans, fishes and shrimps etc., to reach the ultra-fine granularity material of required standard, be specially adapted to the broken or ultramicro grinding of micro mist of prawn, soft-shelled turtle, eel and brood feed.At present, what the bearing of micronizer adopted is the non-maintaining form of band double density capping, and because of the running speed height of micronizer main shaft, bearing temperature under situation about running up rises very fast, and bearing temperature can only be reduced with air-cooled, and result of use is undesirable.Bearing is under the situation of insufficient lubrication, and main shaft and bearing as easy as rolling off a log " freezing " cause the damage of main shaft and bearing together.Be to improve the reliability of bearing, each manufacturer generally adopts imported bearing, and is on the high side, and normal service life is also just about 1 year, and the phenomenon of damage of bearings also takes place equipment in the course of the work easily, causes bigger harm easily.Therefore must provide effective cooling, lubricated environment, the service life of improving equipment to the equipment operation.
Summary of the invention
The purpose of this utility model provides a kind of bearing oil cold type micronizer, by the oil cooling that circulates in the ultramicro grinding machine bearing, to reduce bearing temperature, to improve bearing lubrication, reaches the purpose of micronizer reliable operation.
The technical solution of the utility model: bearing oil cold type micronizer of the present utility model comprises frame, pulverizing chamber, disintegrating mechanism and main power system, feed system, classification aidr bells blast system, main shaft part in the main power system sets up the oil cooled system system separately, on the upper end cover 25 of main bearing seat 13 oil-in 31 is arranged; Oil-out 32 is arranged on the bottom end cover 30, connect into the loop by pipeline and oil pump 33, fuel tank 34 into and out of hydraulic fluid port; Sealing ring 28 is arranged on the contact-making surface of bottom end cover and main bearing seat, packing groove 36 is arranged below bottom end cover, the built-in sealed packing 29 of groove has groove lid 36.1 under the packing groove.
Described bearing oil cold type micronizer, upper and lower end have covered the liquid level gauge connector and have been connected with liquid level gauge 26.
Described bearing oil cold type micronizer has oil sealing 25.1 between upper end cover and the main bearing seat.
The circulating oil path cooling system cooled off in the main shaft of micronizer of the present utility model and bearing adopted; guarantee that main shaft and bearing can operate as normal when running up; improve the lubricant effect of bearing simultaneously by circulating lubricating oil, guarantee that micronizer do not shut down continuous operation.
Design has taken into full account the handling characteristics of micronizer, and its advantage shows the following aspects: designed interior circulating oil path cooling system structure is simple and reliable, is convenient to make and install, and running is reliable.Easy to use, running quality is stablized, can be satisfied the needs of different model micronizer, and can improve the bearing technology in service life.

Fig. 2 is main bearing seat partial structurtes schematic diagrames.
Fig. 3 is a main bearing seat bottom end cover part-structure schematic diagram.
The specific embodiment
As Fig. 1, Fig. 2: bearing oil cold type micronizer comprises frame, pulverizing chamber, disintegrating mechanism and main power system, feed system, classification aidr bells blast system.
The classification aidr bells blast system comprises classification motor 1, classifying turbine axle bed 4, classifying turbine 17, convex cover 7, feed box 5 etc.
Being pulverizing chamber 9 in the tank body 3, is disintegrating mechanism in the pulverizing chamber 9, and disintegrating mechanism comprises the grating disk 14 that main shaft drives, the hammer cutter 19 on the grating disk 14, gear ring 15, fluid dividing cover 16 etc., the 8th, actuating doors.
The 18th, feed system.
Main power system comprises: the clarifier that main bearing seat 13 is fixed on the frame 11 is indoor, main shaft 23 and bearing 21 is installed, spacer 20 in the main bearing seat 13; Main shaft 23 is connected with active force 12.
Micronizer changes the rotating speed or the direction of rotation of classifying turbine 17 by the frequency conversion to classification motor 1, reaches the required granularity of finished product, and the finished product material in discharge chamber 5, is delivered to warehouse for finished product by wind through fluid dividing cover 16 and convex cover 7.Arrive main bearing seat 13 and main shaft 23 by many belt transmission that are installed in the main power system 12 on the frame 11 during work, main shaft drives the hammer cutter 19 on the grating disk 14, material with gear ring 15 bump takes place in pulverizing chamber 9 is pulverized, and pulverized material is delivered in the pulverizing chamber 9 by feed system 18.
