In the invention, the magnetic conductive grid is taken as a filter element, a gradient magnetic filed is formed inside the magnetic conductive grid under the action of the electromagnetic coil, an electromagnet is formed, the magnetic filed intensity is high, the magnetic force distribution is uniform, the adsorbability of the filter element is strong, and the filtering efficiency is high.
Description
Technical field
The present invention relates to magnetic filter, specifically a kind of electromagnetic filter.
Background technology
Magnetic filter is mainly used in the fields such as oil, chemical industry, metallurgy, medicine, machinery, automobile and removes a large amount of iron filings, iron powder and other Ferromagnetic Impurities comprising in various liquid, slurry and gas, and can be used for precious metal catalyst recovery and weak magnetizing mediums clarification etc.
At present, magnetic filter is mainly applied permanent magnet and is removed the ferromagnetic particle in medium as filter core, but because the Distribution of Magnetic Field of permanent magnet is inhomogeneous, causes filter efficiency not high, is difficult to meet some accurate application scenario requiring; In addition, it is backwash medium that magnetic filter is mainly answered water in the process of backwash, and backwash efficiency is low, and the consumption of the water yield is large.
Summary of the invention
The present invention is directed to the problems referred to above, the electromagnetic filter that a kind of Distribution of Magnetic Field is even, filter efficiency is high is provided.
According to technical scheme of the present invention: a kind of electromagnetic filter, comprise the filter with inlet and liquid outlet, in the cylindrical shell of described filter, be provided with magnetic conduction grid, the cylindrical shell of described filter is set with solenoid housing outward, in described solenoid housing, solenoid is installed, described solenoid is surrounded on the periphery of described magnetic conduction grid.
In described solenoid housing, be furnished with cooling water pipe.
Hand-operated butterfly valve, stop valve and the first Pneumatic three-way ball valve are installed on the feed tube of described filter, and a mouth of pipe of described the first Pneumatic three-way ball valve is slag-drip opening.
Electromagnetic flowmeter, the second Pneumatic three-way ball valve and safety valve are installed on the drain pipe of described filter, and a mouth of pipe of described the second Pneumatic three-way ball valve is backwash import.
The bottom of described solenoid housing is fixed with support.
Technique effect of the present invention is: the present invention be take magnetic conduction grid as filter core, and the magnetic field that acts on the inner formation of magnetic conduction grid gradient by solenoid, forms electromagnet, and magnetic field intensity is high, and magnetic force is evenly distributed, and filter core adsorptivity is strong, and filter efficiency is high.
