First, an overview
Pressure screen is my factory digestion and absorption of imported prototype technology developed out of a new type of recycled paper pulp screening equipment. The device characteristics of the design for the impurities in the recycled pulp as l flow structure can be widely used in all kinds of waste paper pulp and the coarse sieve, coarse screening and screening of pulp before the paper machine, has an unmatched combination of good performance and reliability, a variety of domestic pressure screening for the upgrading of products recycled pulp processing.
Second, the principle
Pressure to take the bottom of the screen into the slurry, the bottom row of heavy residue, at the top row of the light residue upflow structural design, to effectively solve the above problems. Light impurities and pulp in the air naturally rise to the top of the slag discharge port, and heavy impurities into the body to the settlement in the end the Ministry of discharge. In this way, on the one hand, effectively shortening the residence time of impurities in the screen area, reducing the possibility of impurities cycle to improve the screening efficiency; the other hand, to prevent damage caused by the weight of impurities on the rotor and sieve drum, to extend the useful life of equipment.
Third, the structural performance
A drum sieve: fine sieve sieve drum slit width H0.15mm,, use the the Imizu cutting slotted 8mm thick steel plate to form a good hole and burr-free notch, not like the mechanical washing mill notch produce stress and groove side cracks. And provides a rigid degree of network technology to improve the wear resistance.
2, rotor rotor rotor: seminal plasma is equipped with 3-4 rotor strict balance correction after assembly, the rotor rotating at high speed vibration. The rotor is installed on the spindle, the rotor through the screw mounted on the rotor, rotor and sieve drum clearance can be adjusted. Coarse sieve rotor using the rotor drum exterior structure and calibration balancing, this structure prevents impurities wound rotor device to work.
Enclosure: cover and cylinder, the cylinder the lower part has a cut to the slurry into the tube. The central cylinder equipped with a plasma tube, cover with slagging and flushing outlet.
4 Transmission: including motor, pulleys, v-belt, the belt tensioning device, the spindle and bearings.
Fourth, the maintenance
Pressure screening in the application process, process water, calcium and magnesium hardness, pH value, conductivity, total alkalinity, temperature and other factors to produce the scaling phenomenon, resulting in the following hazards:
(1) increase the number of unplanned downtime, resulting in the production of intermittent, affecting the production efficiency of the device. Cleaning downtime, increased maintenance costs and additional work load;
(2) cause the paper disease, which affects the product quality;
Increase the consumption of chemicals and pollution load;
Cause accidents in production, and reduce equipment life;
(5) increase the energy loss. The traditional repair methods are shut down chemical cleaning, shut down the high-pressure water cleaning, add scale inhibitor, mechanical cleaning, stop the demolition and replacement, but more time-consuming, and repair the results are unsatisfactory.
To address the problem of foreign advanced maintenance methods to the use of electronic descaling Miriam solve.
Compared with the traditional method of repair, Deco music electronic descaling Miriam operating limits to prevent the formation of pipe scale, rust prevention of bacterial and other even better, while less expenses, do not pollute the environment and water quality in the maintenance of the pressure screen more and more applications.
