Description

TECHNICAL FIELD

[0001] The utility model relates to the field of SMT production, concretely to a cleaning water purification device for SMT production. BACKGROUND

[0002] The cleaning water purification device for SMT (surface mount technology) production is a device for treating cleaning water generated in the SMT production process, which purifies the cleaning water to meet the reuse standard, reduces the dependence on fresh water resources and lowers the production cost.

[0003] The publication number CN212610100U discloses a cleaning water purification device for SMT production, which comprises a filter cylinder and a neutralization tank. The filter cylinder is installed on the upper middle part of the neutralization tank. A coarse filter screen is installed inside the filter cylinder. A fine filter screen is installed below the coarse filter screen. A discharge port is formed on the upper side of the filter cylinder. A bracket is installed on the filter cylinder above the discharge port. Metal iron filings and other impurities are often mixed in the cleaning water. If these impurities are not removed, they will have a serious adverse effect on the subsequent production process. Currently, the common cleaning water purification device usually uses a filter screen to filter metal iron filings. The filter screen can effectively intercept iron filings, so that the cleaning water is preliminarily purified. In order to facilitate the cleaning of the iron filings on the filter screen, a magnet is often used for adsorption cleaning. When the magnet is close to the filter screen, the iron filings will be attracted by the magnet, thereby separating the iron filings from the filter screen. However, in actual use, the filter screen is prone to clogging. This is mainly because as the cleaning water is continuously circulated, more and more iron filings will accumulate on the filter screen. When the iron filings accumulate to a certain extent, the pores of the filter screen will be blocked by a large amount of iron filings. Especially in the case of serious clogging, the iron filings will be tightly stuck on the filter screen, which greatly reduces the cleaning effect of the magnet. At this time, even if the magnet has a certain attractive force, it is also difficult to suck out the tightly clogged iron filings from the filter screen. This situation will reduce the working efficiency of the cleaning water purification device. SUMMARY

[0004] The utility model aims at providing a cleaning water purification device for SMT production, which uses the device to work, thereby solving the problem that the iron filings will be tightly stuck on the filter screen, which greatly reduces the cleaning effect of the magnet.
