and Principle of Iron Remover
1. Magnetic rod cleaning
Magnetic rod iron removal is a kind of iron removal method which
achieves the effect of iron removal by contacting the magnetic
source directly with the slurry. Its cleaning is carried out
under the magnetic state. When cleaning, to overcome the greater
adhesion, magnetic rods should be magnetic cleaned, even if
using high-pressure water jet magnetic rod cleaning method can
not be thoroughly cleaned, and high-pressure water impact will
accelerate the demagnetization of magnetic rods, so it can only
be manual cleaning. The working area is magnetic absorption
area. When cleaning, the scraper is driven by mechanical
structure to scrape impurities into the non-working area, i.e.
without magnetic field. At this time, the impurities are
separated from the magnetic attraction, so only a small amount
of water is needed to clean the impurities on the magnetic rod.
The automatic scraper iron removal machine greatly reduces the
manpower consumption caused by manual cleaning, and the cleaning
cycle is controllable, but the one-time investment is large, and
the iron removal effect is difficult to improve.
2. Cleaning of electromagnetic iron remover
Electromagnetic iron remover is a semi-automatic iron remover,
which removes magnetic impurities in slurry through the current
and magnetic field generated by DC excitation power supply. At
present, the cleaning of electromagnetic iron remover is to
remove the iron-absorbing medium for manual cleaning after the
power is cut off. Because the electromagnetic iron remover can
produce a relatively high magnetic field, it is necessary to
remove and clean the iron-absorbing medium of this honeycomb
structure after a period of time. As the core of the
electromagnet, the iron absorbing medium is composed of lattice
plates. In order to improve the efficiency of iron removal, the
lattice plates are generally arranged densely and it is
difficult to clean in the cavity. It is difficult to clean the
beehive iron-absorbing structure pipeline, and it must be
cleaned by power off. It is difficult to achieve continuous iron
removal by single machine.
3. Cleaning of durable iron remover
This is a permanent automatic cleaning and iron removal machine,
which magnetizes the iron-absorbing medium by the inductive
magnetic field produced by the permanent magnet and absorbs
iron. When the permanent magnet leaves, the iron-absorbing
medium will be de-magnetized. The cleaning of the iron removal
equipment is mainly to clean the iron absorbing medium, which is
a way of demagnetization cleaning. This kind of iron removal
equipment can use high magnetic field and produce higher working
magnetic field, but it does not affect the cleaning effect. In
order to enhance the iron removal effect of the iron remover,
the structure of iron-absorbing medium is generally complex.
Because of the large number of wires, this ingenious
high-pressure cleaning device is adopted.
4. Ultrasound Cleaning The principle of ultrasonic cleaning is
that the high-frequency oscillation signal emitted by the
ultrasonic generator is converted into high-frequency mechanical
oscillation by the transducer and transmitted to the
iron-absorbing medium. The forward radiation of the ultrasonic
wave in the dense phase of the cleaning liquid makes the liquid
flow to produce tens of thousands of tiny bubbles (cavitating
nucleus), and vibrates under the action of the sound field. When
the sound pressure reaches a certain value, the bubbles grow
rapidly. Then it closes suddenly. When the bubble closes, it
produces shock wave, which can generate thousands of atmospheric
pressure around it. When the group particles adhere to the
surface of the cleaning parts, the solid particles are separated
by atmospheric pressure, so as to achieve the purpose of
cleaning the surface. |
