Oil pipe static eraser
Technical field
The utility model relates to petroleum transportation technology, and particularly relate to a kind of oil pipe static eraser, it is applied on petroleum pipeline.
Background technology
Oil product is in storage and transport process, no matter be unload, concoct, store, or defeated turn, pump dress etc., oil product is in flowing, friction all the time.Turn in journey oil product is defeated, oil product and inner-walls of duct friction have a large amount of electrostatic and produce, and along with the oil product with electrostatic constantly enters into terminal container, in terminal container, electrostatic charge constantly accumulates.Work as conditions being possessed, an electrostatic spark will make an oil tank, jack works, an oil truck or an oil tanker, and instantaneously Fire explosion occurs, the fire explosion caused by electrostatic at home and abroad happens occasionally.The feature of oil product through pipelines electrostatic hazard is that electric charge produces in pipeline and pipe fitting, but does not form harm in pipeline, and electrostatic hazard is when after oil product outflow conduit, because charge accumulated is formed caused by high potential electric discharge.Therefore, necessaryly a kind of oil pipe static eraser is provided to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of oil pipe static eraser, because electrostatic is difficult to eliminate the security hidden trouble brought when it can improve the transmission of fluid in prior art.
For solving the problems of the technologies described above, the utility model adopts a kind of oil pipe static eraser, it comprises: housing, be positioned at the current collection metallic plate of housing, be installed on the first magnet on housing and the second magnet, and the earthing member to be connected with described current collection metallic plate, be provided with in described housing around current collection metallic plate, pipeline space between first magnet and the second magnet, described current collection metallic plate is positioned at the both sides of described pipeline space and is provided with segmental arc and is positioned at the extension at segmental arc two ends, described extension is connected to described first magnet respectively with the second magnet and extends hull outside and be connected with described earthing member.
As the further improvement of the technical program, described first magnet and the second magnet are fixed on described housing, and the N pole of described first magnet and the S pole of the second magnet are oppositely arranged, described first magnet and the second magnet are equipped with the arc-shaped inner surface matched with the inner wall shape of pipeline space.
As the further improvement of the technical program, the outer surface that described earthing member is fixed on housing cover on described first magnet and the second magnet, described earthing member is provided with the connecting portion be connected with the extension of described current collection metallic plate, and described connecting portion is held on the both sides of described first magnet and the second magnet.
Compared with prior art, the utility model arranges field regions and current collection metallic plate in pipeline, be used for changing the movement locus of electric charge in fluid by magnetic field, and electric charge to be guided on current collection metallic plate and to be finally grounded by earthing member, whole project organization is simple, eliminate electrostatic efficiency very good, can effectively the electrostatic flowed through in the fluid of field regions be eliminated.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil pipe static eraser described in the utility model.
Embodiment
Refer to shown in Fig. 1, the utility model provides a kind of oil pipe static eraser, and it comprises: housing 10, a pair current collection metallic plate 20 being positioned at housing 10, the earthing member 40 being installed on the pair of magnets 30 on housing 10 and being connected with described current collection metallic plate 20.
Described housing 10 in a tubular form, is provided with circular pipeline space 11 inside it, for flowing through for fluid, described housing 10 offers the slotted eye holding described magnet 30.Described magnet 30 is arranged at the both sides of described pipeline space 11 in pairs, and comprise the first magnet and the second magnet that are oppositely arranged, the N pole of described first magnet and the S pole of the second magnet are fixed on described housing 10, and it is positioned opposite to each other, described first magnet and the second magnet are equipped with the arc-shaped inner surface 31 matched with the inner wall shape of pipeline space 11, and the fluid in described pipeline space 11 flows through between the N pole and the S pole of the second magnet of the first magnet.Described current collection metallic plate 20 is curved and be positioned at the both sides of described pipeline space 11, described current collection metallic plate 20 is provided with segmental arc 21 and is positioned at the extension 22 at segmental arc 21 two ends, the extension 22 at described current collection metallic plate 20 two ends is connected to described first magnet and the second magnet respectively, and to extend to outside housing 10 from the slotted eye housing 10 and be positioned at the both sides of described first magnet and the second magnet, conducting is contacted with the earthing member 40 outside housing 10 to facilitate, described segmental arc 21 is affixed on the internal face of described pipeline space 11, thus, the arc-shaped inner surface 31 of the first magnet and the second magnet is made to be spliced to form annular with the segmental arc 21 of described current collection metallic plate 20, the inner side of this annular is for fluid circulation.The outer surface that described earthing member 40 is fixed on described housing 10 cover on described first magnet and the second magnet, described earthing member 40 is provided with the connecting portion 41 be connected with the extension 22 of described current collection metallic plate 20, described connecting portion 41 is held on the both sides of described first magnet and the second magnet, and contact with the current collection metallic plate 20 of the first magnet with the second magnet both sides, described earthing member 40 is grounded by earth lead.
Thus, under the magnetic fields of the first magnet and the second magnet, the field regions be made up of parallel flux lines is formed at pipeline space 11, this magnetic line of force is orthogonal with fluid circulating direction, when fluid flows through, electric charge in fluid enters into field regions with fluid with certain flow rate, under the effect of Lorentz force (F), free charge in fluid will move along arc trajectory, until drop on described current collection metallic plate 20, and conduct on earthing member 40 by described current collection metallic plate 20, and finally enter the earth through earth lead, electric charge in oil product is " filtered ".Like this, the electric charge produced by Cemented filling oil product would not enter into container (or follow-up equipment) below, serves the electrostatic hazard effect eliminating product pipeline conveying.
The above; it is only most preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; utilize the method content of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, all belong to the scope of claims protection.
