Operation principle:
Ore pulp, when entering in feed pipe 6 through emission of baiting chute 17, due to factors such as impact, collisions, more or less there will be
The phenomenon spattered outside ore pulp, the ore pulp spattered outward is partially into feed pipe 6, and when flowing to seal energy-storaging spring device 4 by gap,
When due to factors such as impact, collisions, emission of baiting chute 17 is when rocking when mobile, and the sealing accumulation of energy in side is moved at place
Spring energy-storage sealing ring 19 in spring assembly 4 is compressed, and the water being fixed with in rubber bag tank on described fixed support 5 is extruded,
Thus its hydraulic pressure is increased dramatically, now, piloted reducer 9 is opened, and is sprayed to by the water in rubber bag tank near feed pipe 6 side
Gap in, the ore pulp in gap is poured to feed pipe 6；With this now emission of baiting chute 17 when rocking to while mobile
Time, the gap of opposite side can increase, and reduces the pressure of water in rubber bag tank simultaneously, thus the water in water inlet pipe 16 is drastically flowed into
In the rubber bag tank of this side, supplement the water yield in rubber bag tank；Further, emission of baiting chute 17 do not rock or shake fatigue resistance little time,
Water inlet pipe 16 is under the effect of external force, endlessly to rubber bag tank water delivery, increases its inside water pressure, makes piloted reducer 9
Open, spray to the water in rubber bag tank, in the gap of feed pipe 6 side, be poured to feed pipe 6 by the ore pulp in gap.
Rubber seal 2 carries out last sealing, it is to avoid part current flow out, and have reached optimal sealing effectiveness.
