Problems solved by technology

But its problems are: 1. High energy consumption; 2. The best degaussing effect cannot be obtained because the speed cannot be increased; 3. The magnetic roller is in a high-speed state for a long time, and the bearings are replaced frequently, so the operating cost remains high.

Abstract

The invention discloses a magnetic density order descending array demagnetizing plate. The demagnetizing plate is structurally characterized in that: S and N staggered permanent magnet steels (06) are arranged on a magnet steel array bottom plate, and the permanent magnet steels are arranged from top to bottom and from big to small; a nonmagnetic substance (08) is embedded among the permanent magnet steels; and the magnetic intensity of the permanent magnet steels meets a descending order of 5,000 to 100gs, and is in oblique linear gradient change. The area of A4 magnet steel array bottom plate units (A4) and the number of unit combination can be freely increased and reduced according to the requirements of demagnetized characteristics, and the size and the magnetic intensity of the arraymagnet steels can be freely adjusted according to the requirements of the demagnetized characteristics; the demagnetizing plate is suitable for large-area demagnetizing operations of ships, submarines, plates, steel lining conveyer belts, vehicles and the like, and is also suitable for small magnetized bodies such as watches, screwdrivers and the like; and the demagnetizing plate breaks through the electric oscillation principle of the traditional demagnetizer with high energy consumption, is maintenance-free, and has no energy consumption, a wide application range and a high popularization value.

Description

technical field [0001] The present invention relates to the field of electromagnetism. Specifically, the present invention relates to a degaussing device for industrial equipment. More specifically, the present invention relates to a magnetic density descending array degaussing board. The magnetic density descending array degaussing board can perform fast degaussing without energy consumption and maintenance. Background technique [0002] In various industrial equipment, for example, in large equipment or devices such as ships, submarines, plates, steel wire-lined conveyor belts, vehicles, etc., as small as watches, screwdrivers, etc. Small equipment, tools, etc., are often due to their electromagnetic The live use of iron components causes the magnetic conductors of the equipment or devices, tools, etc. to be magnetized. After the components of the magnetizer device have been magnetized during use, adverse consequences of use can occur, for which reason demagnetization mus...
