Description

Technical Field

[0001] The utility model relates to the technical field of wastewater purification, in particular to a printing wastewater purification device. Background Art

[0002] Printing wastewater refers to wastewater containing ink, solvents and organic matter generated during the printing process. The printing industry involves almost all industries, such as books and newspapers, packaging, construction, decoration, electronics, electrical appliances and other industries. These industries use paper, ink, film, plate material, fountain solution, adhesive, varnish and car wash water in the printing process, which are important sources of wastewater.

[0003] For example, a purification device for treating printing wastewater (Announcement No.: CN215403642U) includes a shell, a first water pump is fixedly connected to the top of the shell, a filling box is fixedly connected to the left side of the top of the inner cavity of the shell, and the inner cavity of the filling box is filled with a filter filler. The utility model solves the problem that the existing purification device usually has a relatively simple method for purifying printing wastewater during use, which makes it less effective in treating wastewater during the treatment process and may cause certain pollution to the environment. In addition, the structure of wastewater filtration during use is relatively simple, which makes it easy for harmful substances such as debris to remain during the filtration process, which may cause certain inconvenience to the user.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that the above equipment lacks a structure for filtering larger impurities in the wastewater when used. Larger impurities are easily precipitated to the bottom of the sedimentation box and blocked on the filter plate, causing the filter plate to be blocked, affecting the first water pump to extract and transfer the wastewater, and also causing frequent cleaning and maintenance of the filter plate. Therefore, we need to propose a wastewater purification device for printing. Utility Model Content
