Abstract
The utility model provides a magnetic fluid-sealed high-speed dispersion machine, which comprises a shell body and a power shaft, wherein the shell body is connected and sealed with the power shaft though a bearing and a sealing ring. The dispersion machine is characterized in that a magnetic fluid sealing device is further arranged between the shell and the power shaft, the magnetic fluid sealing device consists of a magnetic pole and the magnetic fluid, and the magnetic fluid is positioned at the part of the magnetic pole with the strongest magnetic field. The magnetic fluid-sealed high-speed dispersion machine is convenient in installation, overcomes the defects of the traditional sealing mode, and improves the sealing performance of equipment.
Description
Technical field
The utility model relates to a kind of high speed dispersor, relates to a kind of high speed dispersor that adopts magnet fluid sealing particularly.
Background technique
In many rotating machineries, the quality of sealability is very important.Traditional sealing means has the deficiency of following two aspects: the one, and there be contacting of Sealing and running shaft, thereby produce friction and wear, greatly reduce the working life of seal arrangement; The 2nd, in the high speed rotating shaft sealer, realize leakage sealed very difficulty.High speed dispersor is as chemical field a kind of equipment commonly used, is used to finish that solid-liquid disperses, moistening, depolymerization, stabilization process.Have multiple functions such as hydraulic lifting, 360 degree revolutions, stepless speed regulation.Mix for big quantity of material, not only need very fast processing rate, and sealability is had relatively high expectations, and existing high speed dispersor is generally realized sealing by bearing and seal ring, produce the situation lower seal performance of wearing and tearing at main shaft and bearing and reduce greatly.
The model utility content
The utility model provides a kind of high speed dispersor that adopts magnet fluid sealing for solving above-mentioned prior art problem.
The utility model realizes that the technological scheme that goal of the invention adopts is, a kind of high speed dispersor that adopts magnet fluid sealing, comprise that casing advances and line shaft, be connected sealing with seal ring by bearing between casing and the line shaft, it is characterized in that: also be provided with device for sealing magnetic fluid between described casing and the line shaft, described device for sealing magnetic fluid is made up of magnetic pole and magnetic fluid, and described magnetic fluid is positioned at the strength, magnetic field of described magnetic pole.The magnetic fluid contacting point of described magnetic pole is pointed shape.Described device for sealing magnetic fluid is provided with the 1-4 group.Be provided with permanent magnet between the described device for sealing magnetic fluid.
The beneficial effects of the utility model are, and are easy for installation, overcome the deficiency of conventional seals mode, improved the sealability of equipment.
Description of drawings
Fig. 1, structural drawing of the present utility model.
Among the figure, 1 casing, 2 line shafts, 3 bearings, 4 seal rings, 5 permanent magnets, 6 magnetic poles, 7 magnetic fluids.
Embodiment
Referring to accompanying drawing 1, a kind of high speed dispersor that adopts magnet fluid sealing, comprise casing 1 and line shaft 2, be connected sealing by bearing 3 with seal ring 4 between casing 1 and the line shaft 2, also be provided with 2 groups of device for sealing magnetic fluid between casing 1 and the line shaft 2, be provided with permanent magnet 5 between 2 groups of device for sealing magnetic fluid, described device for sealing magnetic fluid is made up of magnetic pole 6 and magnetic fluid 7, described magnetic fluid 7 is positioned at the strength, magnetic field of described magnetic pole 6, and magnetic fluid 7 contacting points of described magnetic pole 6 are pointed shape.
In the present embodiment, the magnetic field that magnetic fluid, permanent magnet produce through seal clearance form at the pole tip place of magnetic pole liquid ' O " V-shaped ring, thereby the gap is blocked, reach the purpose of sealing.When the shearing force on acting on fluid surpassed yield value, fluid just began to flow.The shearing stress that acts in rotation axis seal on magnetic liquid " O " the type ring is made up of two-part: a part is because the shearing force of the caused by relative motion axle tangent direction between axle and the housing.This power surpasses its yield value, thus magnetic liquid flow in the axle tangent direction, thereby cause the interior friction of magnetic liquid; Another part is because the axial shearing force that the axial pressure difference of " O " type ring both sides produces is relevant with the magnetization biography property of magnetic fluid.But, the general relatively ferromagnetic material of the magnetization intensity of magnetic fluid is much smaller, thereby relative permeability is lower.In actual applications, for improving sealability, magnetic fluid always is in stronger magnetic field.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the utility model although this specification has been described in detail the utility model with reference to each above-mentioned embodiment; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
