Problems solved by technology

During the cleaning process of these cleaning agents, the iron filings and sundries on the surface of the strip will inevitably enter the cleaning agent, causing pollution to the cleaning agent.
[0003] However, in the cleaning process, the cleaning agent is recycled, and the new cleaning agent is only used to adjust the composition. The iron filings and sundries in the recycled cleaning agent will continue to accumulate, and the accumulated iron filings and sundries will inevitably Will affect the cleaning quality of the strip

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0029] figure 1 It is a front sectional view showing the structure of the magnetic drum filter of the present invention, figure 2 It is an upper sectional view showing the magnetic drum filter of the present invention.

[0030] The magnetic drum filter of the present invention can be used alone, and can also be used in series in multiple stages, and the filtering effect can be improved when used in series. In addition, the magnetic drum filter of the present invention can also be used in parallel, and can perform two-way shunt treatment on the cleaning agent circulation system when in parallel. figure 1 The figure shows the case where the two-stage magnetic drum filter connected in series is used in parallel again. By using the magnetic drum filter constituted in this way, the cleaning agent circulation system can be divided into two streams, and each strea...

Abstract

The invention provides a magnetic rotating drum filter which is characterized by comprising a shell with a liquid inlet and a liquid outlet, a magnetic rotating drum arranged inside the shell, an extruding roller which is arranged parallel to the magnetic rotating drum and is used for extruding the magnetic rotating drum, and a scraping roller device for scraping impurities on the surface of the magnetic rotating drum.

Description

technical field [0001] The invention relates to a magnetic drum filter, in particular to a magnetic drum filter used for filtering cleaning agents in the cleaning section of continuous annealing and galvanizing units. Background technique [0002] In the continuous annealing and galvanizing unit, the cleaning section cleans the strip. The cleaning section includes a hot alkali soaking tank, a scrubbing tank, an electrolytic soaking tank, a rinsing tank, etc. These tanks must use cleaning agents to clean the strip. Even for the unwinding unit: 1# and 2# hot alkali soaking tanks, 1# and 2# hot alkali scrubbing tanks and electrolytic soaking tanks use chemical solvents (including NaHO and active agents, etc.), 3# scrubbing tanks and rinsing tanks use desalinated water. In the process of cleaning the strip by these cleaning agents, the iron filings and sundries on the surface of the strip will inevitably enter the cleaning agent, causing pollution to the cleaning agent.
