Description
Technical field
The present invention relates to a kind of steel wire lining conveyor belt degaussing gear, more particularly to a kind of two-way penetration magnetic density descending
Array degaussing gear.
Background technology
After magnetic conductor in industrial equipment is magnetized, will occur adverse consequences, for example：The harbour high speed of certain enterprise is defeated
The steel wire conveying belt of ribbon feeder group, due to being influenceed again and again by tramp iron separator electromagnet, magnetization phenomenon is very serious；The steel being magnetized
Silk conveyer belt, when by metal detector, constantly interference produces misoperation.If steel wire lining conveyor belt without
Demagnetization, soon whole conveyer belt be magnetized in Zhou Xunhuan, metal detector can not be differentiated the miscellaneous iron of steel scrap in ore,
Consequence can be very serious.For the demagnetization application technology of steel wire lining conveyor belt, prior art has magnetic roller cylinder degausser, suspension type to disappear
The state-of-the-art technologies such as magnetomechanical, magnetic density order descending array demagnetizing plate, these technologies ensure that the operation peace of harbour high-speed conveyer belt unit
Entirely.But these new technologies also have some shortcomings part, such as：Steel wire rope ＞ Ф 8mm in steel wire lining conveyor belt when
When the junction that demagnetization bad phenomenon, particularly steel wire lining conveyor belt just occurs is waited equal to one times of steel wire rope, one side
" magnetic density order descending array demagnetizing plate " will seem that erasing characteristics is not enough, it is necessary to increasing magnetic density and magnetic intensity could solve
Problem.Chinese patent 201110043672.7 discloses a kind of steel wire conveying belt Non-energy-consumption demagnetization method and device, and the patent is explained
What is stated is a kind of lining conveyor belt demagnetization method for being suitable for below steel wire rope Ф 8mm, and the patent applies the " magnetic of one piece of one side
Density descending array demagnetization plate ", according to the arrangement of gradients feature of rare earth magnetic steel, the magnetic intensity penetrates the steel wire of ＜ Ф 8mm solid matters
Rope has no problem, as shown in Figure 2 a, when the steel wire rope of ＞ Ф 8mm solid matters, and the demagnetization magnetic line of force that demagnetization plate is produced is several
Shielded, occur in that the magnetic flux density on the side of steel wire rope two in conveyer belt is unequal, have impact on the another of steel wire rope in conveyer belt
Face erasure effect.Although the steel wire lining conveyor belt application of current Ф 5mm~Ф 8mm class specifications is the most universal, with China
Industrial development trend, Ф 10mm or so steel wire lining conveyor belt application also will popularization.
The content of the invention
It is an object of the invention to provide a kind of two-way penetration magnetic density order descending array demagnetizing device, the degaussing gear energy
The problem of existing steel wire conveying belt demagnetization technology is directed to the demagnetization deficiency of super thick steel wire lining conveyor belt is made up, can be realized to super thick
The purpose of steel wire lining conveyor belt demagnetization.
In order to realize above-mentioned technical purpose, the present invention is adopted the following technical scheme that：
A kind of two-way penetration magnetic density order descending array demagnetizing device, including fixed mount, demagnetization plate, folder plain-barreled roll framework, folder
Plain-barreled roll；The fixed mount has by floor installation is provided with two blocks of demagnetization plates between some vertical beams, vertical beam, every piece of demagnetization plate bottom

The staggered permanent-magnet steel of S, N, by magnetic field intensity by it is strong to it is weak, arrange from up to down, magnet steel is inlayed non-magnetic each other
Material；The magnetic intensity of permanent-magnet steel array is in skew lines graded, and is descending.Demagnetization plate 12 is two pieces, two pieces of demagnetizations
The corresponding magnetic pole of plate 12 is opposite, area and equal sized, homogenous materials, the magnetic line of force produced by the corresponding magnetic pole of two blocks of demagnetization plates
Reference can be made to 15 and Fig. 2 b in Fig. 1.Steel wire lining conveyor belt 1 sequentially pass through on folder plain-barreled roll framework 5 a pair of folder plain-barreled rolls 3, two pieces
Gap between demagnetization plate 12, passed after a pair of folder plain-barreled rolls 31 on lower folder plain-barreled roll framework 51.The running direction of conveyor belt 2 and demagnetization
The direction of successively decreasing that the magnetic field intensity of the internal magnetic pole of plate 12 arrangement generation is descending is identical.
Referring to Fig. 2 b, now the steel wire rope in steel wire lining conveyor belt 1 be placed in N, S magnetic pole to wearing between, two magnetic poles
Air line distance shorten, doubled corresponding to the steel wire rope magnetic strength in conveyer belt, and in conveyer belt the side of steel wire rope two magnetic flux density
Equity.According to demagnetization principle：When with given pace（Such as speed ＞ 2.5m/s）Steel wire lining conveyor belt in traveling passes through N, S not
Break off a friendship replace, in the middle of two pieces " magnetic density order descending array demagnetizing plates " that magnetic strength is descending when, the remanent magnetism in steel wire lining conveyor belt
Because constantly in the presence of additional alternating magnetic field and magnetic strength successively decrease, the remanent coercivity in steel wire rope is overcome, so as to reach
Demagnetization purpose is arrived.Due to the steel wire rope in steel wire lining conveyor belt be placed in N, S magnetic pole to wearing between so that the side of steel wire rope two
Magnetic flux density equity, add one times equal to the demagnetization thickness of steel wire conveying belt is made.
Referring to Fig. 5 a and Fig. 5 b, expression is eccentric mobile adjuster adjustment state and the method for adjustment of folder plain-barreled roll framework.
Fig. 5 a are eccentric mobile adjuster use state figure（Turn right）, when spanner turns right, folder plain-barreled roll framework just moves right
It is dynamic；Fig. 5 b are eccentric mobile adjuster use state figure（Turn left）, when spanner turns left, press from both sides plain-barreled roll framework just to the left
It is mobile；After adjustment is finished, the fixing bolt pressed from both sides on plain-barreled roll framework is fastened, with anti-loosening.
Referring to Fig. 6, Fig. 6 is the degaussing gear adjustment schematic diagram of the present invention, adjusts the purpose of folder plain-barreled roll framework, being exactly will be fast
The operating steel wire lining conveyor belt of speed, fifty-fifty runs in the guide the centre of two pieces " magnetic density order descending array demagnetizing plate ", realizes defeated
Send the side of band two and the distance of demagnetization plate impartial, to reach optimal erasure effect.Method of adjustment can be according to actual conditions, can be with
Upper homology, can also the unilateral adjustment of up or down.
Demagnetization plate in the degaussing gear of the present invention is to be fixedly mounted, and presss from both sides one is fixedly mounted respectively on plain-barreled roll framework up and down
To folder plain-barreled roll, the effect of two couple folder plain-barreled roll is to stablize conveyer belt to run in the guide in the middle of two blocks of demagnetization plates.
Conveyer belt is to run from top to bottom in an embodiment of the present invention, and demagnetization plate is vertically-mounted.The present invention's disappears
Magnetic device can also be horizontally mounted, conveyer belt level run, and its erasure effect reached is substantially with vertically-mounted effect
Identical.
These are only presently preferred embodiments of the present invention, be not intended to limit the scope of the present invention, therefore, it is all
Any modification, equivalent substitution and improvements made within the spirit and principles in the present invention etc., should be included in the protection model of the present invention
Within enclosing.
