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,

Example Embodiment

[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 cross-sectional view showing the magnetic drum filter of the present invention.

[0030] The magnetic drum filter of the present invention can be used alone, or can 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 the cleaning agent circulation system can be subjected to two-way shunting treatment when in parallel. figure 1 The magnetic drum filter in series in two stages is shown in the case of being used in parallel. By using the magnetic drum filter constructed in this way, the cleaning agent circulation system can be divided into two ways, and each branch is processed in t...

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.
