Description
Technical field
The utility model relates to reactor and stirs technical field of sealing technology, more particularly, relates to a kind of magnetic driving equipment and a kind of gas-liquid reactor.
Background technology
Along with the development of chemical industry technology, increasing chemical plant installations is tending towards maximizing, the serialization development.Continuous reaction apparatus is generally many reactor series connection, and when wherein the stirring seal member generation leakage of a reactor needed repairing, whole production line must stop production at once, and the loss that namely stops production is bigger.So the sealing reliability to continuous reaction apparatus is had relatively high expectations, particularly gas-liquid reactor.Advantages such as sealing is reliable because magnetic driving equipment has, handling safety generally adopt magnetic driving equipment (being also referred to as magnetic sealing device or magnetic drive device) to realize stirring sealing.
Magnetic driving equipment mainly comprises interior magnet steel assembly, the cage in the magnet steel assembly outside and cover in the outer steel assembly of cage outward in covering in.Wherein, cage is made by nonmagnetic substance; The outer steel assembly comprises outer steel matrix and the outer steel that is positioned on the outer steel matrix; Interior magnet steel assembly comprises: interior magnet steel matrix, interior magnet steel in being coated on the magnet steel matrix, the shaft that two ends link to each other with blender with interior magnet steel matrix respectively, realize upper bearing (metal) and lower bearing that shaft rotates, place the inner pedestal of upper bearing (metal) and lower bearing, be used for the packing seal mechanism of sealing shaft and reactor.Power is magnet steel and shaft in magnetic coupling is delivered to, and realizes the rotation of shaft, and then drives blender work.But because rotary power is by the rotating magnetic field transmission, cage can produce eddy current when cutting magnetic line, and eddy current makes the temperature of cage raise.The rotating speed of shaft is more high, and the temperature rise of cage is just more high, and when rotating speed reaches 500rpm when above, the higher temperature of cage descends and cisco unity malfunction the magnetic force of magnet steel, causes magnetic driving equipment to lose efficacy.
At present, in order to reduce the temperature rise of cage, cage and inner pedestal are designed to integral structure, thereby reduce the diameter of cage.Reduce the diameter of cage under the uniform pressure, then can reduce the thickness of cage, realize reducing the temperature rise of cage, avoid magnetic driving equipment to lose efficacy because the temperature of cage is higher.Magnetic driving equipment mainly comprises interior magnet steel assembly, the cage in the magnet steel assembly outside and cover in the outer steel assembly of cage outward in covering in.Wherein, cage is made by nonmagnetic substance; The outer steel assembly comprises outer steel matrix and the outer steel that is positioned on the outer steel matrix; Interior magnet steel assembly comprises: interior magnet steel matrix, interior magnet steel in being coated on the magnet steel matrix, the shaft that two ends link to each other with blender with interior magnet steel matrix respectively, realize upper bearing (metal) and lower bearing that shaft rotates, upper bearing (metal) links to each other with cage respectively with lower bearing, is used for the packing seal mechanism of sealing shaft and reactor.Wherein, upper bearing (metal) is positioned at the top of cage, and lower bearing is positioned at the bottom of cage.
But, cage and inner pedestal are designed to integral structure, make the thinner thickness of the cage between upper bearing (metal) and the lower bearing, the undercapacity of cage more easily causes the shaft vibration, damages upper bearing (metal) and lower bearing, particularly lower bearing finally influences the rotation of shaft.
In addition, the thinner thickness of the cage between upper bearing (metal) and the lower bearing makes cage more easily be damaged under the alternate stress that shaft applies, and has bigger potential safety hazard.
In addition, upper bearing (metal) is fixed on the top of cage, and lubricating oil must be filled with the whole space in the cage, lubricating oil does not just have free surface, the power consumption that the magnet steel assembly rotates in lubricating oil in causing is bigger, and the mechanical energy of consumption is transformed into heat energy again, makes transmission efficiency reduce.In addition, because the outer steel assembly that cage is rotated covers, the air at cage top is difficult to discharging, and upper bearing (metal) is damaged because of insufficient lubrication.
In sum, how a kind of magnetic driving equipment is provided, to improve the intensity of cage simultaneously in the temperature rise that reduces cage, reduces the vibration of shaft, and then reduce upper bearing (metal) and the impaired probability of bearing, be present those skilled in the art's problem demanding prompt solution.
