Description
Technical field
The present invention relates to magnetic filter, specifically a kind of electromagnetic filter.
Background technology
Magnetic filter is mainly used in removes a large amount of iron filings, iron powder and other ferromagnetism impurity that comprises in various liquid, slurry and the gas in the fields such as oil, chemical industry, metallurgy, medicine, machinery, automobile, and can be used for precious metal catalyst recovery and weak magnetizing mediums clarification etc.
At present, magnetic filter is mainly used permanent magnet and is removed the ferromagnetic particle in the medium as filter core, but because the Distribution of Magnetic Field of permanent magnet is inhomogeneous, causes filter efficiency not high, is difficult to satisfy some accurate application scenario that requires; In addition, magnetic filter is mainly answered water in the process of backwash be the backwash medium, and backwash efficiency is low, and the consumption of the water yield is big.
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 that has inlet and liquid outlet; Be provided with the magnetic conduction grid in the cylindrical shell of said filter; The cylindrical shell of said filter is set with the solenoid housing outward, in the said solenoid housing solenoid is installed, and said solenoid is surrounded on the periphery of said magnetic conduction grid.
Be furnished with cooling water pipe in the said solenoid housing.
Hand-operated butterfly valve, stop valve and the first Pneumatic three-way ball valve are installed on the feed tube of said filter, and a mouth of pipe of the said first Pneumatic three-way ball valve is a slag-drip opening.
Electromagnetic flowmeter, second Pneumatic three-way ball valve and the safety valve are installed on the drain pipe of said filter, and a mouth of pipe of the said second Pneumatic three-way ball valve is the backwash import.
The bottom of said solenoid housing is fixed with support.
Technique effect of the present invention is: the present invention is a filter core with the magnetic conduction grid, and the magnetic field that acts on the inner formation of magnetic conduction grid gradient through solenoid forms electromagnet, and magnetic field intensity is high, and magnetic force is evenly distributed, and the filter core adsorptivity is strong, and filter efficiency is high.
Description of drawings
Fig. 1 is a perspective view of the present invention.
Fig. 2 is a structure cutaway view of the present invention.
The specific embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1, Fig. 2, comprise filter 1, solenoid housing 2, Hand-operated butterfly valve 3, stop valve 4, the first Pneumatic three-way ball valve 5, electromagnetic flowmeter 6, the second Pneumatic three-way ball valve 7, safety valve 8, inlet 9, slag-drip opening 10, coolant outlet 11, cooling water inlet 12, backwash import 13, liquid outlet 14, magnetic conduction grid 15, solenoid 16, cooling water pipe 17, support 18 etc.
Like Fig. 1, shown in Figure 2; The present invention is a kind of electromagnetic filter, comprises the filter 1 that has inlet 9 and liquid outlet 14, is provided with magnetic conduction grid 15 in the cylindrical shell of filter 1; The cylindrical shell of filter 1 is set with solenoid housing 2 outward, and the bottom of solenoid housing 2 is fixed with support 18.Solenoid 16 is installed in the solenoid housing 2, and solenoid 16 is surrounded on the periphery of magnetic conduction grid 15.
Also be furnished with the cooling water pipe 17 that is used for cooling off solenoid 16 in the solenoid housing 2.Cooling water pipe 17 links to each other with cooling water source with cooling water inlet 12 through coolant outlet 11.
The mouth of pipe that Hand-operated butterfly valve 3, stop valve 4 and the first Pneumatic three-way ball valve, 5, the first Pneumatic three-way ball valves 5 are installed on the feed tube of filter 1 is a slag-drip opening 10.
The mouth of pipe that electromagnetic flowmeter 6, the second Pneumatic three-way ball valve 7 and safety valve 8, the second Pneumatic three-way ball valves 7 are installed on the drain pipe of filter 1 is backwash import 13.
The present invention is a filter core with magnetic conduction grid 15; The magnetic fields that act on magnetic conduction grid 15 inner formation gradients through solenoid 16; Form electromagnet; When pending medium passed through magnetic conduction grid 15 inside, close magnetic-particle was attracted to magnetic conduction grid 15 inside, and clean medium is through the 15 back discharges of magnetic conduction grid.
When the inner close magnetic-particle of filter core is adsorbed onto a certain amount of the time; The inlet outlet pressure differential at filter core two ends begins to strengthen; When the pressure reduction of importing and exporting reaches setting value, turn off the magnetic field of the power supply removal magnetic conduction grid 15 of solenoid 16, carry out backwash through backwash import 13.The mode that backwash adopts gas-liquid to combine, through the backwash of gas and liquid dual mode, backwash is thorough, and fault rate is low, and easy to maintenance simple, backwash efficiency is high.Endless form is adopted in backwash, has reduced the use amount of water, and operating cost is low, long service life.
The control employing PLC of system Programmable Logic Controller of the present invention, backwash mode has pressure reduction and time two kinds of control modes, and automaticity is high, and is safe and reliable to operation.
The present invention adopts electromagnet as filter core, and magnetic field intensity is high, and magnetic force is evenly distributed, and the filter core adsorptivity is strong, and filter efficiency is high.
