超级多级筛选系统

Equipment overview

As an important screening equipment in the pulping process, a pressure screen is indispensable in production. 低碳环保型生产制浆。 In recent years, the competition in the paper industry has become increasingly brutal, requiring low- carbon, environmentally friendly production pulping with high output and low consumption . 术,根据浆种不同工艺要求不同,研发了多级压力筛 (包括:多级压力筛、 多级分级筛多级筛选分离机 )等筛选设备。 Traditional pressure screens are no longer suitable for the current production and operation requirements of paper mills. Based on the operating conditions of traditional pressure screens, and through digestion and absorption of foreign technologies , according to the different requirements of different pulp types, we have developed multi-stage pressure screens (including: Pressure sieve, multi-stage sieve , multi-stage sieving separator ) and other screening equipment. Multi-stage pressure sieve (hole screen, slot screen) introduction: Multi-stage pressure sieve replaces the traditional pressure sieve one-stage three-stage screening process in production. 直排。 The screening is completed once inside the multi-stage sieve, and the tailings are discharged straight.

部进浆、底部排重渣、顶部排轻渣的升流结构。 Multi-stage pressure sieve (hole screen, slot sieve) principle characteristics: Multi-stage pressure sieve generally uses two to four screening areas to screen slurry (most of the currently used are three screening areas) bottom slurry feeding, bottom drainage Upflow structure of slag and light slag on top. 搭配使用。 Each screening area has its own good pulp outlet. According to the type of slurry and process requirements, the good pulp at each outlet can be reasonably matched and used.

第三筛选区。 The slurry enters the slurry through the bottom and passes through the first screening area. After screening, the remaining slurry is mixed with diluted water and raised to the second screening area. After the second screening, the slurry is mixed with secondary dilution water and enters the third screening area. Three-stage screening good pulp is available or can be returned to the previous process. The tailings are discharged straight and the fiber loss is low. The effect is very obvious in the actual operation of multiple paper mills.

Product advantages

1. Small footprint, one multi-stage screen completes the screening process of multiple traditional screens.

2. Simplified pulping process, reduced pulp pond, slurry pump and pipeline settings, and reduced investment costs.

3. Low power consumption, only about 40% -50% of traditional screening.

4. The tailings are discharged straight, the fiber loss is low, and the fiber loss rate can be reduced below 1%.

5. Simple operation and low maintenance cost.

效率,对杂质破坏作用小。 6. The rotor is equipped with anti-impurity and coil winding functions, and the fins with guide grooves further improve the screening efficiency and have less damage to impurities.

7. It has self-cleaning function to prevent the fouling of the sieve drum.
