振框式平筛用于筛除纸浆悬浮液中的各种粗大杂质。 用于纸浆的粗选、净化。通过频率振动将粗浆中的骨节,薄膜及其它粗大杂质筛出。良浆经过筛板进入下道工序,该机具有结构简单、维修简便、生产费用低、生产效率高等优点,是制浆生产理想的浆料筛选净化设备。本设备分为高频振框式、低频自洗式、高频自振式三种。
The vibrating frame type flat screen is used for sieving all kinds of coarse impurities in pulp suspension. It is used for rough selection and purification of pulp. The joint, the thin film and other coarse impurities in coarse pulp are screened out through frequency vibration. The fine pulp enters the next process through sieve plate. The machine has the advantages of simple structure, simple maintenance, low production cost and high production efficiency. It is an ideal pulp screening and purification equipment for pulping production. This equipment is divided into three types: high frequency vibration frame type, low frequency self washing type and high frequency self vibration type.

工作原理

本筛由筛框、振动系统、减振装置、浆槽等部件组成。

浆料自浆箱由进浆管进入筛框,浆与渣节通过筛板进行分离,筛好的浆料进入浆槽,并由出浆口排出,而未蒸解的纤维杂物则由筛框的端部进入除渣槽排出。    

本筛通过浆位调节装置来调节浆槽的浆位,浆位的高低影响浆料筛选时的压力差及筛框振动阻力的大小,浆位高, 筛选出来的浆料质量高,产量低,浆位低时则相反。

筛框的振动是由电机带动偏心轮来实现的,减振机构是由四个弹簧把筛框支撑起来,具有结构简单,实用性能好等优点。

筛框的上部设有喷水装置筛选时,可根据用量大小而调整,筛板孔径有八种规格即ф2.5、ф3、ф4、ф5、ф6、ф8、ф9、ф10毫米,二种材料即1Crl8Ni9Ti和A3板,用户可根据需要订货。
 

Working principle
 
The sieve is composed of a sieve frame, a vibration system, a damping device and a slurry tank.
 
The slurry enters the sieve frame from the sieve box through the sieve tube. The slurry and slag section are separated through the sieve plate. The sifted slurry enters the sieve tank and is discharged from the outlet. The non-evaporated fibre impurities are discharged from the end of the sieve box into the slag removal tank.
 
The sieve adjusts the slurry level of the slurry tank through the slurry level adjusting device. The slurry level affects the pressure difference and the vibration resistance of the sieve frame during sieving. The slurry level is high, the quality of the selected slurry is high, the output is low, and the opposite is true when the slurry level is low.
 
The vibration of the screen frame is realized by the eccentric wheel driven by the motor. The vibration absorber is supported by four springs, which has the advantages of simple structure and good practical performance.
 
When the screen frame is screened by water spraying device, it can be adjusted according to the size of the dosage. There are eight sizes of sieve plate aperture, i.e. ф2.5, ф3, ф4, ф5, ф6, ф8, ф9, ф10mm. Two kinds of materials, i.e. 1Crl8Ni9Ti and A3 plates, can be ordered by users according to their needs.
