MAIN FEATURES

a•  Pollution handling capability; high effective sand out purification: over;

b•  Failure ratio of simple operated oscillating screen is low and its installation, operation and maintenance is convenient;

c•  Slag materials screened by advanced straight-line oscillation have a very good dewatering efficiency;

d•  Adjustable exciting force of oscillating screen, face and mesh size can make the system to have a good screening efficiency in all strata;

e•  Screening efficiency of oscillating screen is so high that a kind of all drillers can bore and feed in various strata;

f•  Energy saving efficiency is significant because the power factor of oscillating motor is high and power consumption is low;

g•  Low operation noise of oscillating screen is favorable to improve the working condition;

h•  Abrasion and corrosion resisting centrifugal mud pump (slag mortar pump) has the following advantages: advanced construction, highly level commonality, reliable operation, convenient assembly and dismount, simple maintenance etc. The thicker abrasion resisting parts and the balance-type support can make the pump to convey the strong corrosive and abrasive, high concentration slag mortar;

i•  The hydraulic cyclone with advanced construction parameter has an excellent mud and sand-sorting index. The corrosion and abrasion resisting and the lightweight of cyclone material can run in the worst condition without maintenance and has the following features: convenient operation and adjustment, economic and durable;

j•  The new fluid level automatic balancing device can not only hold the stable fluid level of mud reservoir, but also handle mud repeatedly in order to increase purification quality further;

k•  The unique recoil device can prevent mud reservoir from silting and flooding in order to run normally and long term;

l•  In the part of electric control, the logical control system of electric relay is adapted with simple wiring, strong capability of anti jamming and convenient maintenance.

Working principle

 

Sewage slurry which needed to deal with is transported to the pre-screen of slurry treatment system, and through two layers screening, particle size is greater than 3 mm of gravel, clay is separated out; and then the slurry get into the slurry storage tank of two sets desander, slurry pump pumping the slurry from storage tank, and from primary hydro-cyclone the tangential into pulp inlet, after hydro-cyclone separation, fine particle size of mud discharged by the bottom of cyclone fall into the vibrating screen, after dewatering and separating by screen, dry slag is separated out. First level of hydro-cyclone separate the slurry which cut point is d50 60um from upper get into the slurry tank; slurry pump pumping the slurry from storage tank, and from secondary hydro-cyclone the tangential into pulp inlet, after hydro-cyclone separation, fine particle size of mud discharged by the bottom of cyclone fall into the vibrating screen, after dewatering and separating by screen, dry slag is separated out. Second level of hydro-cyclone separate the slurry which cut point is d60 20um from upper get into the other side of slurry tank. This is the clean slurry which we final need.

It is mainly used in reversing or positive port (launder) in hydroelectric power, civil engineering, bridge pile foundation work and also used in tunnel shield to purify mud in cycle. It can cut down construction cost and reduce environmental pollution. Increase efficiency of making hole. It is necessary equipment for civilized construction.
