Product introduction: Drum grille decontamination machine, also known as spiral press grille or spiral fine grille, is a front sewage treatment process, suitable for urban sewage, industrial wastewater and domestic wastewater treatment projects, intercepting floating objects in water, integrating pollution blocking, spiral lifting, squeezing grid slag as one, is the current comparison process of fine grille decontamination machine. The whole set of drum grille is composed of: rotating mesh barrel, net barrel tray, front and rear rings and slag plate, conveying press, bracket, driving device, flushing device, etc. Working principle: Rotate the cleaning net in water for 5-8 weeks per minute at an inclination angle of 35°, and 1/3 of the net is submerged in water. Sewage and floating matter enter the inside of the net from the lower port of the net, and the floating matter is attached to the inner wall of the net and taken out of the water. When the net is turned to a point, the impurities fall into the garbage conveying system due to gravity, and are conveyed and pressed to the discharge port. The filtered sewage flows through the gap of the net cylinder. Application scenario: The drum grille decontamination machine integrates decontamination, transportation and squeezing to improve energy utilization and reduce management investment. Since the net cylinder gap is fixed, the rotary drum grille decontamination machine cleans the dirt, overcomes the defect of the gap movement of the ordinary rake tooth grille, and the decontamination efficiency is above 98%. Both ends of the net cylinder are welded and fixed with the net barrel by cutting thick stainless steel rings with high concentricity to ensure the concentricity of the mesh during rotation. The spiral rotation power of the conveying and pressing device comes from the same reducer rotating with the net barrel. The conveying and pressing spiral is a shaft spiral, and the spiral blade is processed from stainless steel. The pitch from bottom to top slowly decreases, and the pressing capacity gradually increases.
