Melamine foam production sewage treatment device and treatment method based on centrifugal separation and impurity removal

Abstract

The invention relates to the technical field of sewage treatment equipment, and particularly discloses a melamine foam production sewage treatment device and method based on centrifugal separation impurity removal, the device comprises a first treatment box and a water inlet pipe arranged on the left side of the first treatment box and used for feeding sewage, and a grabbing assembly used for removing fibers in the sewage is arranged in the first treatment box; a water outlet in the lower right side of the first treatment box is connected with a second treatment box used for conducting secondary purification on sewage, and a secondary purification unit used for purifying the sewage is arranged in the second treatment box. And in the later period, fiber impurities on the grabbing rod can be automatically removed and scraped off, and the impurities are rapidly blown away through airflow, so that self removal of the impurities is completed, and the subsequent impurity removal operation is greatly simplified.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment equipment, specifically a melamine foam production sewage treatment device and treatment method based on centrifugal separation and impurity removal. Background technique [0002] Melamine foam, also known as melamine foam or Mena-melamine foam, is a new type of sound-absorbing, heat-insulating and thermal insulation material. In addition to its excellent sound absorption, heat insulation and fire resistance, melamine foam also has the advantages of high flame retardancy, environmental protection, hygiene and safety compared with similar products such as glass wool and polyurethane foam. Melamine foam ideally meets the growing demands for sound insulation in vehicle construction. Melamine foam is made from felt, fiber, sheet metal and plastic molded into shape-matching fittings that can be used as soundproofing materials or mufflers. [0003] During the processing of melamine foam, the ...

Problems solved by technology

[0003] In the process of melamine foam processing, the raw materials need to be washed intensively. During the washing process of raw materials, a lot of sewage will be generated, and the fiber impurities in the sewage will block the pipeline. Regarding the method of removing fibers in the sewage, there is an existing patent announcement The patent No. CN109179523B discloses a sewage treatment device for the production of hair products for sewage treatment, in which the springs used are used to capture the fibers in the sewage, but this way of catching is to remove the fibers from the sewage, but cannot capture the fibers The fiber is removed in time, but it is also very difficult to remove the fiber impurities on the spring in the later stage. It needs to be cut with a knife a little bit, which is extremely time-consuming and laborious. Based on this, a melamine foam production sewage based on centrifugal separation and impurity removal is now provided. Processing device and method
