The utility model has the advantages of reasonable structure and convenient operation, the surface damage of the rollers caused by hard rolling foreign matters can be effectively prevented, the impact of the rollers without materials can be avoided, the service life of the rollers is prolonged, the throughput is increased, and the utility model can reduce the machine use and save the space for large-scale oil factories.

Description

Hydraulic pressure pair roller flaker

The utility model relates to a kind of novel, hydraulic pressure pair roller flaker.

The producer of the flaker of China's production at present is a lot, YYPY2 * 60 * 125 types as the production of Changzhi, Shanxi, 50-100t/d hydraulic pressure flaker that Jining, Shandong produces, treating capacity is little, being not suitable for large-scale oily factory uses, when roll shop building enters foreign matter, the oil pressure of oil pocket increases severely, and makes pressure switch work, control solenoid directional control valve dead electricity, be in a roller state, to lay down pressing force between rolls, prevent rigid rolling, damage roll surface, but real work shows, too high because of roll rotational speed, when electrical equipment also never reacted, foreign matter had passed through roll, promptly actual rigid rolling taken place, electrical equipment on the pumping plant produces action and lags behind, and when not expecting in the hopper, causes roll not have the material bump.

The purpose of this utility model provides a kind of foreign matter that can prevent between roller and damages roller surfaces, when hopper does not have material, roll is separated automatically, prevents that roll from not having material bump, the hydraulic pressure pair roller flaker that day output strengthens.

The utility model mainly is made of buffer bin, material level automaton, feeding mechanism, magnetic separation mechanism, hydraulic pressure, spring adjusting device, movable roll, stationary roll, roller motor, feeding roller motor and hydraulic power unit motor, and wherein material level automaton, hydraulic pressure, spring adjusting device and roll size are the inventive points of present technique.

The utility model is rational in infrastructure, and is easy to use, can prevent effectively that the rigid foreign matter that rolls from causing roller surfaces to damage, and prevents roll not have the material bump, prolongs roll service life, and treating capacity strengthens, and can make large-scale oily factory reduce machine consumption, conserve space.

The following describes embodiment of the present utility model:

The utility model is mainly by buffer bin 1, material level automaton 2, feeding mechanism 3, magnetic separation mechanism 4, hydraulic pressure, spring adjusting device 5, movable roll 6, stationary roll 7, roller motor 8, feeding roller motor 9 and hydraulic power unit motor 10 constitute, wherein material level automaton 2 is installed in the buffer bin 1, by adjusting bolt 11, compression spring 12, contact 13, contact 18, portable plate 14, hinge 15 and control cabinet shell 16 constitute, the adjustment bolt 11 that wherein can adjust control cabinet shell 16 and horizontal plane angle withstands on the front end of control cabinet shell 16, the elastic strength of compression spring 12 is adjusted by nut 17, one end of portable plate 14 is connected with control cabinet shell 16 with hinge 15, the plate body be placed on compression spring 12 and contact 18 above, move along with moving of portable plate 14 contact 18, when the material level in the buffer bin 1 is enough high, portable plate 14 is with compression spring 12 compressions, contact 18 contacts energising, machine run with contact 13; When the material level in the buffer bin 1 was lower than setting value, compression spring 12 was with portable plate jack-up, and separate with contact 13 contact 18, and feeding roller stops feeding automatically, and the pumping plant commutation makes roll separately, prevented that roll from not having the material bump, causes the limit; When material level reached specified altitude again, pumping plant closed roller again, the feeding roller mechanical feed.

Hydraulic spring grease cup adjusting device 5 is made of cylinder cover 19, sealing ring 20, cylinder block 21, piston 22, nut 23, bolt 24, spacing adjustment nut 25, screw thread key 26, arc-shaped pad 27, outer spring seat 28, outer spring 29, inner spring seat 30, inner spring 31, look nut 32, thrust bearing 33, movable axis bearing 34, ball pad 35, piston rod 36 and dial 37, wherein outer spring 29 and inner spring 31 are contained in

spring base

28 and 30, and outer spring seat 28 is enclosed within the outside of inner spring seat 30, and can slip on inner spring seat 30.During machine works, when entering foreign matter between roller,, the yielding function is arranged promptly, so before pumping plant is not also worked, rigid rolling is converted to soft rolling and that the rolls damage degree is dropped to is minimum because of spring can continue compression.

Movable roll 6 and stationary roll 7 that present technique is applied on the hydraulic pressure pair roller flaker can adopt day output big, and diameter is φ 800mm, and length is the roller of 1250mm, make large-scale oily factory reduce machine consumption, conserve space.
