Abstract

The utility model relates to a strong magnetic pipeline protector, which belongs to a rust-resistant, scale-resistant and scale-removing protecting device for the pipeline. The utility model is composed of a permanent magnet, a guard plate, fixing screws, etc. The utility model is mainly characterized in that the permanent magnet is fixed between two concentrators with full symmetric sizes and shapes; the concentrators, etc. are fixed together by screws; one side of each of the concentrators is fixed with an outer wall of the pipeline. The protector has the advantages of small volume and compact structure; the magnetic field strength is as high as 20000 gauss. The utility model is good equipment for solving the scale, the oxidation and corrosion and the alga blockage in equipment or pipelines, such as boilers, heat exchangers, various cooling systems, Venturi pipes in steel factories, ash exhausting pipes in power plants, etc.

Description

Strong magnetic tube pipe protection device

The utility model belongs to the protective gear to the antirust antiscaling, descaling of pipeline.

At present, in fields such as oil, chemical industry, traffic, metallurgy, food, colliery, medicine and heat exchange, the corrosion of pipeline, the scale removal problem is a unsolved for many years big problem.In recent years, utilize the permanent-magnet material scale removal, though carried out various trials some effects are arranged, but because its mechanism study and cognition is not dark, mentality of designing is indeterminate, product performance do not reach requirement, its structure generally is divided into two kinds, a kind of is in the pipeline outside, and in pipe, the another side of permanent magnet is the concentrating flux plate of soft iron with the N utmost point of permanent magnet or the S utmost point.The structure of this kind descaler mainly is that the magnetic intensity of magnetizer is not high, penetrates indifferent, the DeGrain of tube wall; Another kind of structure mainly is that magnet ring is fixed in the pipeline, and medium is passed through from magnet ring, and this kind structure, magnet ring itself are perishable, easy oxidation, and the pipeline internal medium flow is obstructed, effect is also bad.

The purpose of this utility model is to provide a kind of simple in structure, and magnetic intensity is very high, antiscale, the extraordinary strong magnetic tube pipe protection device of descale effect.

The realization of the utility model purpose theoretically according to the faraday principle, when conductor dbus is crossed magnetic field, during cutting magnetic line, produces the principle of electric current in the conductor." aqueous medium " in pipeline; by being installed in the magnetic field on the pipeline, " aqueous medium " in the pipeline just produced electric current, makes steel pipe walls be the negative electricity effect; " aqueous medium " pipeline non-scaling; in pipeline, existing incrustation scale can also come off; according to anodic attack; the principle of cathodic protection makes not oxidation of pipeline, not corrosion.Its structure is that the center is a permanent magnet, and permanent magnet is outward a concentrator, is backplate outside permanent magnet, concentrator, by screw or rivet they is solidly installed.Because the ingenious design of concentrator utilizes magnetic induction and magnetic reactance principle, make the protector pole strength up to 10000～20000 Gausses, and leakage field is lower than 800 Gausses.

Performance characteristics of the present utility model is: one, pole strength is up to 20000 Gausses, two, liquid in pipe flow through this device, be ionized, three, magnetic energy produces potential difference between tube wall and liquid, and four, utilize steel pipe secondary cumulative, obtain the better effect of ionization.

In conjunction with the accompanying drawings, concrete structure of the present utility model is described.

The utility model (Fig. 1) is made up of permanent magnet (1), backplate (5) and backplate set screw (4) etc., its main feature is to be fixed with permanent magnet (1) between symmetrical fully two concentrators (2) of size shape, and concentrator, backplate etc. is solidly installed by screw (4), one vertical face of concentrator (2), with permanent magnet and neat, another vertical face (arc surface) is connected mutually with pipeline (3) outer wall.

Fully two of symmetry or polylith are formed (figure 1., scheme 2.) to concentrator of the present utility model by size shape, its profile A face is the garden cambered surface, all the other each faces are the plane, and the angle of A face and B face, B face and C face, C face and D face is corner angle (acute angle, right angle, obtuse angle), or are the garden arc.

Permanent magnet of the present utility model is a neodymium iron boron, and it is shaped as rectangle, square, it can be an integral body or the polylith assembly sticks into.

The utility model can be inhaled on the pipe outer wall by magnetic force, a cover can be installed also can overlap more.Its first kind embodiment (Fig. 4) is installed, two cover permanent magnetic strong magnetic protectors is 180 degree at cross section installs; Second kind embodiment (Fig. 5) is installed, three cover protectors is 120 degree at cross section installs; The third installs embodiment (Fig. 6), the quadruplet protector is 90 degree at cross section installs; This product can be installed in above three kinds of situations on the same cross section with novel, also can press the axial direction of pipeline by vertically installing on different cross sections, (Fig. 7) along pipeline outer wall in the shape of a spiral line equidistantly distribute installation.

The pipeline that the utility model links to each other with concentrator is a steel pipe.But use can link to each other with the pipeline of non-steel.

Permanent magnetic strong magnetic pipeline protector volume is little, compact conformation, and magnetic field intensity is Up to 20000 Gausses, need not keep in repair, maintenance, long service life, be to solve The Wen Qiuguan of boiler, heat exchanger, various cooling system, steel mill, power plant Scaling in ash releasing tube etc. equipment, the pipeline, existing incrustation scale scale removal and anti-oxygen Change the good device of the problems such as corrosion and the obstruction of algae mud, just have service conduit Normal work, the service life of extension device and pipeline, energy-conservation and protection of the environment etc. Advantage.
