High-magnetic-field-intensity pipeline deironing device capable of cleaning automatically

Abstract

The invention discloses a high-magnetic-field-intensity pipeline deironing device capable of cleaning automatically, belonging to deironing devices. The deironing device is characterized by mainly consisting of a box body, a magnetic body device, a pneumatic device and an electrically control device; the box body is of a rectangle; a feed inlet pipe arranged above, a discharge pipe arranged below and a deironing pipe are welded on an upper side panel and a lower side panel of the box body; an inner baffle plate is welded at the right side of the feed pipe and the discharge pipe in the inner cavity of the box body; axial mounting holes are arranged in rows symmetrically on a left end panel, a right end panel and the inner baffle plate of the box body; magnet devices composed of sleeve pipes and magnetic bars penetrate in each axial mounting hole on a coaxial central line; a feed blocking ring is welded on a middle section of each sleeve pipe; the left end and the right end of each sleeve pipe are connected with a pneumatic device which is composed of an air compressor, a left two-position five-way pneumatic electromagnetic valve and a right two-position five-way pneumatic electromagnetic valve; and compressed air is induced in each sleeve pipe to drive the magnetic bar to move left to right to absorb iron and perform deironing. The pipeline deironing device has high magnetic field strength, good deironing effect and long service life.

Description

technical field [0001] The invention belongs to a pipeline iron remover, in particular to a pipeline iron remover with high magnetic field strength. Background technique [0002] The existing pipeline iron remover used in the production of chemical industry, glass, ceramics, refractory materials, food and other industries usually uses pipeline manual iron remover, and its working principle is: separate the inlet and outlet of the pipeline iron remover It is installed on the pipeline for conveying materials with a flange. The material in the pipeline enters from the feed port of the iron remover, and the ferromagnetic impurities mixed in the material are absorbed by the magnetic field generated by the permanent magnet assembly installed on the side or in the middle of the iron remover. On the surface of the magnet, although the iron removal effect of this pipeline iron remover is good, it must be shut down after a period of use, and the ferromagnetic impurities adsorbed on th...

[0002] The existing pipeline iron remover used in the production of chemical industry, glass, ceramics, refractory materials, food and other industries usually uses pipeline manual iron remover, and its working principle is: separate the inlet and outlet of the pipeline iron remover It is installed on the pipeline for conveying materials with a flange. The material in the pipeline enters from the feed port of the iron remover, and the ferromagnetic impurities mixed in the material are absorbed by the magnetic field generated by the permanent magnet assembly installed on the side or in the middle of the iron remover. On the surface of the magnet, although the iron removal effect of this pipeline iron remover is good, it must be shut down after a period of use, and the ferromagnetic impurities adsorbed on the magnetic plate must be manually removed. If it is not removed in time, it will easily form a blockage and seriously weaken the iron removal. Effect; utility model patent "Pipeline iron remover with automatic iron removal function", patent number: 200820036456.3, adopts the method of guiding the ferromagnetic impurities adsorbed on the suction surface to the discharge surface, because the discharge surface gradually moves away from the magnet, under the force of gravity Under the action, ferromagnetic impurities break away from the discharge surface and fall into the iron discharge port; in order to discharge reliably, the patent proposes to set at least a non-magnetic section without magnetic material on the cross-sectional circumference of the magnet. The iron remover used It is an open-circuit magnetic system. Although it can automatically remove iron from the pipeline, the efficiency of iron removal is greatly reduced due to the low magnetic field strength and small magnetic field gradient in the working area of ​​the open-circuit magnetic system.
