Abstract

The invention discloses a curved screen adjustable feeding system, and relates to the technical field of filtration treatment of wastewater. The curved screen adjustable feeding system comprises a pulp feeding pipe and a feeding device, wherein the width of a discharging hole of the feeding device is same as that of a screen plate of a curved screen; the discharging amount and the pressure of thedischarging hole are adjustable, and a water curtain of the discharging hole can be uniformly distributed on the screen plate of the curved screen, so that the utilization ratio of the screen plate ismaximized; meanwhile, pressure-type pulp feeding is realized, the screening capacity of equipment is obviously increased, and therefore, the screening efficiency of the equipment is effectively improved. In an operation process, according to the requirement of the screening capacity, the opening of the discharging hole is adjusted correspondingly, and the flow rate and pressure of pulp at the discharging hole can be adjusted; in addition, the opening of the discharging hole of the feeding device can be adjusted without stopping the equipment when in operation, so that the feeding system is wide in adjusting range, wide in application range and novel in structure, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of wastewater filtration and treatment, in particular to an adjustable feeding system for curved sieves. Background technique [0002] In the APMP pulping process, a large amount of waste water will be generated during the process of washing wood chips. Solid substances such as wood chips and fibers in the waste water must be separated from the waste water, and the waste water will be recycled again, so as to realize the comprehensive utilization of waste liquid and the compliance treatment of waste , to meet the requirements of my country's "resource-saving, environment-friendly, technologically innovative" green paper industry. Curved sieve equipment is an ideal equipment for wastewater treatment in the current market. It has low power consumption and good treatment effect, and has won wide acclaim from the majority of paper-making enterprises. [0003] At present, most of the feed pipes of curved sieves a...
