넳 넲

The electromagnetic iron remover is composed of a carbon steel box and a built-in electromagnetic coil to form an electromagnetic field loop, and an electromagnetic field is generated in the center of the coil. The barrel with the magnetic medium passes through the center of the coil. The magnetic field is captured by the magnetic medium and then amplified to form a high gradient, High field strength sorting area; when the material passes through the magnetic medium from top to bottom, the magnetic material is adsorbed on the magnetic, so as to realize the separation of magnetic impurities.

barrel is equipped with two counter-rotating vibration motors to apply up and down high-frequency vibrations to the barrel, thus realizing the passability of ultra-fine materials.

magnetic dielectric network. The separation valve is controlled by PLC program, thus realizing automatic iron removal and slag discharge of the equipment.

characteristics

● Rubber shock absorber is used to support the vibration cylinder, which can solve the defect that the leaf spring shock absorber is easy to break and the defect that the coil spring shock absorber has poor lateral support;

● The magnetically conductive medium is designed with 22 layers. The effective magnetic field sorting area can reach 450mm height. The number of layers and the height of the magnetic field area are higher than those of other brands in the market. The more magnetically conductive medium layers, the more magnetic materials can be adsorbed under the same demagnetization conditions. The working efficiency of the equipment is 20 ~ 25% higher than that of the same specifications in the market. The capture probability of magnetic substances in materials is increased by 5 ~ 10%.

● Due to the fragility of stainless steel threads, the medium fixing method is fixed with standard parts. For equipment of the same specification, the cost of spare parts for demagnetizing machines of our company can be saved by 50 ~ 70% per year.;

● The demagnetization machine is equipped with a medium disassembly and hoisting arm, which makes it more convenient and quick for front-line workers to clean and maintain the medium. With the same specification of equipment, the daily maintenance labor cost of our demagnetization machine can be reduced by 50 ~ 70%, and the efficiency can be improved by more than 30%.

● The special cooling system oil circuit circulation design can ensure the heat dissipation of the electromagnetic coil and will not cause damage to the local temperature rise. Under the condition of ensuring normal cooling water circulation and regular maintenance, our company promises to ensure the service life of the electromagnetic coil More than 10 years.

● Control system adopts electromagnetic coil excitation constant current design

(PLC automatic voltage regulation) does not require manual adjustment due to the decrease of magnetic field caused by the increase of coil temperature;

● Special structural design of automatic material distribution valve, no bolts and other detachable parts on the side of material channel, while ensuring sealing performance, can also prevent bolt loosening during long-term operation, resulting in foreign matter mixed into materials.

● The material channel can be sprayed with PTFE/ETFE to reduce the risk of magnetic foreign matter introduction.

operability

█ The electric control cabinet uses a touch screen (HMI) to operate, which is convenient to operate. At the same time, the dynamic display content of the screen can monitor the running status of the equipment in real time, and the detailed alarm prompt information can ensure that the equipment fault information is fed back to the operator at the first time;

█ Different operation permissions on touch screens facilitate the management department to manage the permissions on process parameters;

█ The working magnetic field (Gaussian value) is displayed in real time, and a low Gaussian value alarm can be set to avoid demagnetization failure;

█ Real-time monitoring of cooling oil and cooling water flow;

█ You can set the work quota for each shift and stop the machine after the demagnetization is completed.

magnetically conductive medium

magnetic conductive medium is generally made of 430 ferritic stainless steel, which has excellent magnetic conductivity and good corrosion resistance.

to measure the advantages and disadvantages of magnetically conductive media, it is mainly seen that when the electromagnet is energized, it must have good magnetic conductivity. After the electromagnet is powered off, it must be demagnetized in a very short time, otherwise the magnetic objects will not fall. In the process of welding and processing, the internal crystal structure of 430 stainless steel will change locally. Therefore, the magnetically conductive medium needs to go through a complicated heat treatment process to achieve demagnetization and corrosion resistance. According to different material characteristics, our company uses a variety of different specifications of magnetic media to achieve the best iron removal effect.
