Technical Field

The utility model relates to a filtration equipment technical field, concretely relates to vertical picture peg filter of automatically cleaning.

Background

The vertical plate-inserting filter is a small-volume and high-precision filtering device, and is widely applied to the industries of pharmacy, chemical industry, food and the like.

In the vitamin C production process, after the acidification reaction in the conversion workshop is finished, the produced acidification liquid is decolored by adding activated carbon in a decoloration tank, and the decolored liquid containing carbon enters a vertical flashboard filter to complete the removal of waste carbon. When the operation pressure of the filter reaches 0.4Mpa, the cover is opened to wash the waste carbon intercepted on the filter plate. The cleaning is needed for 3 times per shift, and the screw is needed to be manually disassembled when the cover is opened and the cover is put on, so that the labor intensity is high. Frequent opening and closing of the cover also accelerates the wear of the sealing gasket, causing leakage risks. The smell of methanol is large when the cover is opened to wash the site, and the site is easily polluted by the splashed waste water. Meanwhile, as the slag discharge port is arranged at the closing port of the filter, the risk of blockage is caused during slag discharge.
