Electromagnetic dryer
1, technical field
The utility model relates to a kind of papermaking drying plant, a kind of specifically electromagnetic dryer.
2, background technology
Under the prior art, the general steam-type drying unit that adopts in paper technology, this device needs special boiler and pressure piping, use combustion mediums such as coal, so cause increase on the cost and the pollution on the environment easily, the Chinese patent notification number be CN2112647U patent disclosure a kind of " paper grade (stock) ultra redray drier ", its structure comprises infrared pipe, though this mode of heating has been avoided environmental pollution and has been reduced production cost, but, cause weak points such as drying effect is not good easily because the radiation of infrared tube is inhomogeneous.
3, summary of the invention
The purpose of this utility model is at above weak point, provide a kind of simple in structure, production cost is low, environmentally safe, energy consumption is low, floor space is little, guarantee product quality, be fit to the electromagnetic dryer that use the coastal and big and medium-sized cities of resourceful southern area of water generating and environmental requirement strictness.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electromagnetic dryer, form by drying cylinder housing, Meissner oscillator, fixture, transmission device and computer automation control device, fixture comprises support, cursor and fixed axis, the fixed axis two ends that top of the trellis is horizontally set with link to each other with the drying cylinder housing by cursor, on the fixed axis between two cursors, be fixed with Meissner oscillator in the drying cylinder housing, cursor links to each other with motor by transmission device, and Meissner oscillator and motor are controlled by the computer automation control device.
Electromagnetic dryer of the present utility model is compared with prior art, have simple in structure, production cost is low, environmentally safe, energy consumption is low, floor space is little, guarantee product quality, be fit to the characteristics such as coastal and big and medium-sized cities use of resourceful southern area of water generating and environmental requirement strictness, except that the above, the utility model also possesses: non-pressure vessel need not strict sealing and enough withstand voltage mechanical strengths; The heat transfer efficiency height; Temperature is easily regulated: characteristics such as maintenance of equipment is simple, rapid, thereby, have good value for applications.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the structural representation of electromagnetic dryer;
Accompanying drawing 2 is the side structure schematic diagram of electromagnetic dryer.
5, the specific embodiment
Explain below with reference to Figure of description electromagnetic dryer of the present utility model being done.
Electromagnetic dryer of the present utility model, its structure is made up of drying cylinder housing 1, Meissner oscillator 2, fixture, transmission device 3 and computer automation control device, fixture comprises support 4, cursor 5 and fixed axis 6, fixed axis 6 two ends that support 4 tops are horizontally set with link to each other with drying cylinder housing 1 by cursor 5, on the fixed axis 6 between two cursors 5, be fixed with Meissner oscillator 2 in the drying cylinder housing 1, cursor 5 links to each other with motor 7 by transmission device 3, and Meissner oscillator 2 and motor 7 are controlled by the computer automation control device.
During use, drive motors 7 rotates drying cylinder by cursor 5, and Meissner oscillator 2 behind the feeding electric current, just has the magnetic line of force to pass through near casing wall in the drying cylinder housing 1, and the size of magnetic flux depends on exciting current intensity; When drying cylinder housing 1 rotates, thereby cylinder wall cutting magnetic is encouraged line generation electric current (eddy current), and drying cylinder housing 1 just is heated.The size of heat that casing wall produces depends on the size of exciting current and the rotating speed of drying cylinder, and heated drying cylinder housing 1 promptly can be used to carry out the oven dry of paper.
The speed of a motor vehicle of paper machine, the mass dryness fraction of page and dry speed are passed through reponse system, are controlled by the computer automation control device.
Its processing and fabricating of electromagnetic dryer of the present utility model is very simple and convenient, can process use shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
