Description
Technical field
The utility model relates to powder equipments, the in particular to structure of high temperature crushing and classification system level machine.
Background technique
Existing high temperature crushing and classification system level machine is as shown in Figure of description 1,2,3, its powder to be fractionated when working
Raw material with high temperature gas flow along solid arrow direction by reaching grader shell 1 inside shell 1 with the region between grading wheel 2, point
Under the effect of the drag of step cone centrifugal force and air-flow, the particle of granularity qualification passes through the impeller clearance of grading wheel 2 with high temperature gas flow,
Enter head 7 along arrow direction, and be discharged by the discharge port on head 7, the centrifugal force that bulky grain can be graded wheel 2 is got rid of to classification
The inner wall of casing body 1 falls along inner wall, is collected or is crushed by the powder device of grader lower end.Due to being the air of high temperature,
Therefore use water-cooling bearing block 8, water-cooling bearing block 8 is designed as big pipe sleeve tubule, seals the hollow sandwich structure at both ends, by into
Water pipe leads to the bottom end of interlayer, and outlet pipe leads to the top of interlayer, cools down to cooling water is led in its interlayer, water-cooling bearing block
Upper end is equipped with upper ball cover 9, and upper ball cover 9 is equipped with upper bearing (metal) oil filling pipe 14, and is equipped with exhaust outlet.The lower end of water-cooling bearing block
Equipped with lower ball cover 5, lip type rotating seal ring is housed inside lower ball cover 5, is cooperated with 3 outer circle of main shaft, main shaft 3 is by being mounted in water cooling
The upper and lower bearing support at 8 inside both ends of bearing block.Labyrinth lid 4,4 meeting of labyrinth lid are housed in the main shaft outer circle in 5 outside of lower ball cover
It is rotated together with main shaft, labyrinth lid 4 is labyrinth cooperation with lower ball cover 5, prevents powder granule from entering bearing block internal exergy dissipation with this
Bad bearing.Grading wheel 2 is assemblied in the lower end of main shaft.The upper end of water-cooling bearing block 8 is with 7 top inner hole of head, and lower end is by machine
Bearing block support ring 6 inside head lower end supports, and support ring 6 is welded by 8 round steel one end with head inner wall, the same support ring in one end
The welding of 6 outer circles is as support.Head 7 is fitted with motor cabinet 11, and motor cabinet 11 is fitted with motor 13, and motor 13 passes through shaft coupling
Device 12 is connect with main shaft 3, and grading wheel is driven to rotate.Head 7 is assemblied in the upper surface of grader shell 1, and grading wheel 2 is located at classification
The inside of casing body 1.Existing this structure is applied in the crushing and classification system of high temperature gas flow and powder material, and there are following
It is some insufficient:, can be directly with the lower end of water-cooling bearing block and lower ball cover first is that during high temperature gas flow and powder flowing
Lower end surface and outer circle face contact cause heat to be easy on transmitting bearing block lower end and related shafting components, cause bearing block
Hole size becomes larger, and bearing, which is acted as a travelling agent, justifies damage bearing and bearing block, while also can lubricating grease be melted, and bearing is allowed to lose too early
Effect；Second is that not accounting for adverse effect caused by the temperature transmitting of axis in existing program takes cooling measure, high temperature gas flow to axis
It is directly contacted with lower ball cover and axis with powder, the temperature on lower ball cover and axis can be allowed to increase quickly, can be mounted in lower axle
The lip type rotating seal ring premature aging failure inside lid 5 is held, in this powder system, many ultra-fine powder particles are easy for
Labyrinth seal is crossed, into lower bearing, leads to bearing damage；Third is that 7 top inner wall of head and bottom end bearing seat supports ring 6 are direct
It is contacted with high temperature gas flow and powder, metal (upper seat both ends can be transferred heat to indirectly, there is no water cooling intercept heat at this,
Adverse effect can be caused to top shafting components, meanwhile, because heat is upward always, also can to the motor 13 mounted in 7 top of head
It toasts for a long time, will increase motor temperature rise, be unfavorable for motor radiating；Fourth is that having this scheme, due to the relationship of assembly, lower axle
Hold inconvenient setting tank filler sleeve.Therefore it refuels difficult, also results in bearing premature failure.
Summary of the invention
The purpose of this utility model is that the deficiency of prior art scheme is directed to, by changing water cooling position, by more preferable
Lubrication, increase air coolant seal, block heat source to a greater extent, to reduce in high temperature crushing and classification system temperature to classification
