Description
Technical field
The utility model belongs to the Cereals Processing Machines apparatus field, specially refers to utilize Frequency Induction Heating grain-drying device.
Background technology
China is a grain big country, annual grain yield reaches about hundred million tons of 6-7, according to incompletely statistics, the grain-producing area is annual owing to can not obtain timely airing and oven dry, cause the grain that goes mouldy and lose, account for about 10% of total output of grain, be subjected to environmental limit owing to shine to dry in the air naturally, thereby the mechanical drying problem of grain, mentioned the critical positions of national economy.Present domestic oven dry and the water removal device that is used for grain, though multiple structure and model are arranged, majority all is to belong to the coal-burning boiler heat supply, the type of drying tower dehydration.They are to adopt hot blast as drying medium, be that the heat energy that produces when utilizing fuel combustion adds hot-air, mode with convection current or conduction heats grain, reach the drying dewatering purpose, but there are many weak points in this traditional approach, the boiler combustion thermal conversion efficiency is low excessively, generally about 7%-10%, most of heat with soot emissions in atmosphere and consume in vain, again to airborne release great amount of carbon dioxide and dust, thereby also serious pollution environment, the sulfur dioxide that is produced has caused the heavy corrosion of equipment again, has reduced service life of equipment.And Hong Gan grain by this way makes it second-rately bring loss for storage, export trade of grain, and the said equipment uses near the silo of emphasis fire prevention unit simultaneously, in the time of also and existence that can system of Himdu logic fire and initiation fire.On the grain heat-drying problem, how to seek new approach, improvement is updated the equipment for this reason, just becomes imperative research project, my new thermal source and drying unit thereof of seeking grain heat-drying of being engaged in, be exactly with above-mentioned need be the research project of aim.
Summary of the invention
The utility model technical issues that need to address, be the quality of, contaminated air low at the existing heat energy efficiency that exists in the use of coal-burning boiler, oven dry grain as grain drying device in order to overcome not good, easily many weak points such as disaster hidden-trouble are arranged, and redesign a kind of Frequency Induction Heating grain-drying device that utilizes, to overcome above-mentioned deficiency.The purpose of this utility model relies on following technical scheme to realize that a kind of Frequency Induction Heating grain-drying device mainly comprises crop inlet pipe, cereal elevator, deduster, drying tower, grain dischzrging tube.It is characterized in that, an electric current of intermediate frequency inductive transducer is set in this device, it is connected the output of intermediate frequency power supply cabinet as load, intermediate frequency power supply cabinet front portion is connecting the capacitor group, this power cabinet is connected to the computer operation table that is subjected to its control, the return pipe of cooling water is connected in the air preheater, and the warm air of being sent by this preheater leads in the electric current of intermediate frequency inductive transducer through water filter.After dry warm air by transducer is heated intensification, use for drying tower, to reach energy-conservation purpose.
Described electric current of intermediate frequency inductive transducer, it contains the aluminum alloy casing of a garden tubular, shell inner close fitting one deck rare earth material heat insulation layer, they surround the electric current of intermediate frequency induction coil that one deck is turned to by hollow copper tubing, the internal layer of circle posts mica insulator, and the center of garden tube is the transformation of ownership steel core of high permeability.When induction coil has electric current of intermediate frequency to pass through, there is the very strong magnetic line of force to pass through on the special steel core, make tube center, garden concentrate very big heat energy, heat energy makes the air heat of passing through, and is delivered to grain drying tower, and grain is dried.Described intermediate frequency power supply cabinet, it has the broadband output performance, can export the multiple frequency in (1000-8000) HZ scope according to payload, described computer operation table, it can control the electric parameter of intermediate frequency power supply cabinet, the operating desk panel is provided with ammeter I, voltmeter V, power meter P, frequency meter F, can select different electric parameters according to payload, this drying unit can be made series of products, its specification is pressed the cereal day output and is divided, be divided into six grades by 100 tons to 700 tons, corresponding above-mentioned rating connage, at load voltage value V is that can to regulate rated power under the 380V situation respectively be 250KW-2000KW, and selected frequency is the medium-high frequency section of the Mid Frequency of 1000HZ to 8000HZ.
The beneficial effects of the utility model are, this Frequency Induction Heating grain-drying device conversion efficiency height, do not produce the pollution to environment, quality is well dried in the temperature required maintenance of cereal that can accurately regulate oven dry to temperature controlling, can not produce naked light thereby stop disaster hidden-trouble.
