Abstract
The utility model relates to a magnetic treater for grains belonging to a grain post-treatment equipment, which is composed of a grain bucket, a magnetic treater and a grain discharging valve, wherein, the magnetic treater is composed of a permanent magnet, a yoke, a grain separating plate, a fixing plate, etc. The magnetic treater for grains does not need dynamic force and can magnetize various grains and seeds; in the magnetized grains and seeds, the speed of the water inside the seeds transferring outwards is raised. The utility model can improve the efficiency and save the energy when drying and can kill various fungi and repress the breed of the fungi; the utility model reduces the mildew and rot in shelf time and raises the rate of emergence, prompting the increase in yield of crops. The magnetic treater has favorable effect in the combination with a drying machine.
Description
The utility model belongs to the frontier science of theory of magnetism and agricultural engineering.
Magnetics in the application of every field more and more widely in recent years, application study is agriculturally also being carried out in a deep going way, after magnetic field acts on cereal and seed, can improve seed germination rate, can make crops improve output, can kill the mushroom on cereal and the seed and suppress breeding, reduce going rotten of cereal, and can accelerate the speed that the cereal internal moisture shifts to the outside, improve drying efficiency and save the energy.But there is the magnetic processor that can handle cereal and seed in a large number that can directly apply to production at present domestic end still.
The purpose of this utility model:
Develop a kind of suitable agricultural production needs, without power, have the magnetic field intensity of cereal and seed demand, make cereal and seed by the time reach the magnetization effect, can handle the vertical magnetic processor of cereal and seed in a large number.
Content of the present utility model:
The cereal magnetic processor is by the grain bucket, magnetic processor, the valve of putting out cereal is formed, the grain bucket can temporarily store cereal, in time supply with the required cereal of magnetic processor, the put out cereal flow of valve controlled cereal, magnetic processor is by permanent magnet, yoke, compositions such as grain dividing plate, for obtaining certain magnetic field intensity, and according to the difference of cereal treating capacity, permanent magnet that can quantity is different is vertical to be arranged in parallel, adopt this arrangement mode, can make full use of the magnetic energy product of permanent magnet, improve the magnetic field intensity in gap, utilize minimum permanent magnet and form the highest magnetic field intensity and maximum cereal passage.According to the magnetic Circuit Design theory, by required magnetic field intensity, rationally select permanent magnet and yoke for use, according to the magnetic circuit computing formula:
LmSm＝ (BgHg)/(BmHm) LgSg （1）
(in the formula: Lm-magnet thickness, Sm--magnet area, Lg--magnetic field gap width, Sg--magnetic field interval area, the magnetic flux density of Bm--magnet, the magnetic field intensity of Hm-magnet, the magnetic flux density in gap, Bg--magnetic field, the magnetic field intensity in gap, Hg--magnetic field).
Can make permanent magnet volume minimum thus, the operating point should be selected near the maximum magnetic energy product, utilizes formula:
Lm＝ (fHgLg)/(Hm) （2）
Sm＝ (σBgSg)/(Bm) （3）
(f--reluctancy, σ--magnetic leakage factor), rule of thumb can just decide f and σ, and Bg, Hg then is designing requirement, Lg and Sg can be decided by the magnetic processor structure earlier temporarily, can obtain Lm and Sm, check then, select the magnetic conductance computing formula by magnetic structure, obtain the magnetic conductance Gg in total magnetic conductance G of magnetic circuit and gap, magnetic field by formula, by formula:
σ＝ (G)/(Gg) （4）
Can obtain magnetic leakage factor, again by formula:
tyθ＝ (Lm)/(Sm) G （5）
Can obtain the slope of operating load line, the intersection point of the demagnetizing curve of this straight line and permanent magnet is the operating point of permanent magnet, gets final product with just reconnaissance is identical as this point, as differ bigger, then each size of magnetic circuit and parameter should redefine, and repeat above calculating, till meeting design requirement.
The yoke size is calculated by following formula and is determined:
Sb≥ (BmSm)/(Bb) （6）
(the Sb--yoke section is long-pending, and the Bb-yoke is in the magnetic flux density at maximum permeability place), by following formula as can be known, Bb and Sb are inversely proportional to, and only choose the big material of Bb value and just can dwindle the yoke size, and the magnetic property of electrical pure iron is good, the Bb value is bigger, and moderate, is the suitable material of yoke.
Scope of design of the present utility model is:
Treating capacity: the 5-50 ton/hour,
Material passes through the time: 1-8 second,
Magnetic flux density in the gap: 0.05-0.4 tesla.
Good effect of the present utility model:
1, cereal and the seed after the processing can be accelerated the speed that its internal moisture shifts to the outside, can improve the rate of drying and the thermal efficiency when drying, can save the energy, can also make paddy rice and soybean reduce " quick-fried waist " phenomenon when drying.
2, can increase seed germination rate, improve the yield and quality of crops.
3, can kill and suppress the mushroom breeding of cereal and seed, reduce cereal and seed going rotten in storage period.
4, the water transport between the quickening cereal, after the cereal mixing with different in moisture content, the water content of cereal reaches poised state very soon, obtains needed moisture, can increase economic benefit.
Description of drawings:
Accompanying drawing 1 is the sketch of cereal magnetic processor, and 1 is the grain bucket, and for magnetic processor provides material, 2 is grain dividing plate, cereal is flowed down smoothly, and 3 is yoke, can link up magnetic circuit, and 4 is permanent magnet, 5 is the magnet backplate, and 6 is the magnet fixed side, and 7 is the magnet gripper shoe, and 8 are the valve of putting out cereal.The grain bucket is connected with bolt with the magnetic processor and the valve of putting out cereal, the permanent magnetism basis 4 of magnetic processor is to be folded up and down by grain dividing plate 2 and magnet gripper shoe 7, and both sides are enclosed fixing by the magnet backplate 5 of magnet fixed side 6 and front and back mutually, and be connected with annular yoke 3 with bolt, form the strong magnetic factory of porous cereal passage.During work, cereal at first enters the grain bucket, relies on gravity to flow into the gap magnetic field that is formed by the several piece permanent magnet through grain dividing plate, magnetizes processing, after the valve outflow of putting out cereal.
The grain bucket can be kept in material, and provides material to magnetic processor, makes its flow even, and magnetic processor is the core, and is extremely relative by several piece permanent magnet N, S, forms several uniform magnetic fields, and constitutes the loop by yoke, and material flow promptly was magnetized through magnetic field moment.The valve of putting out cereal is the outflow in order to the control material, and the size that can regulate mass flow.
Most preferred embodiment:
Magnetic processor is by the several piece permanent magnet, magnet backplate and yoke are formed magnetic loop, for reducing magnetic resistance, strengthen magnetic field intensity, can adopt permanent magnets such as permanent-magnet ferrite with high-coercive force and neodymium iron boron respectively, yoke adopts the good electrical pure iron of magnetic conduction, grain dividing plate, fixed head and gripper shoe are made with the stainless steel of plastics or nonferromagnetic, also can be according to needs with two magnetic processor main body polyphones, between connect with a thick plastics dottle pin, the cereal magnetic processor should be installed in the drying process, cereal and seed are after magnetization is handled, directly send in the dryer, carry out drying and handle, can improve drying efficiency, save the energy, reduce going rotten of shelf time, can improve seed germination rate again, increase the output of crops.
