Driving lever on door-hinge, there is provided give rotary door body pretension door closing force, now proximity switch send instruction normal condition, counter weight construction to
The inclination of water inlet chamber direction, weighted spherical ball torque is equally provided to door body pretension door closing force.
Because door body is enabling clockwise, when microfroc filter starts water inlet first, i.e., door bottom hydraulic pressure provides door closing force
Square, the chamber depth of water of being intake when microfroc filter normal work is higher than door body, and water inlet enters filter cylinder, water outlet from water inlet chamber top
Chamber water level is not less than the top of door, i.e., in front of the door after be totally submerged with water, but water inlet chamber water level is higher than water outlet chamber water
Position, eccentric door-hinge overcentre door body water pressure slightly larger than door-hinge central lower door body water pressure, produce by this pressure differential downwards
Raw torque is closed the door torque less than the foregoing pretension of door body, and door-hinge is also beneficial to door by the moment of rolling friction that hydraulic pressure is produced
Close, door body is in the completely closed state.Xiamen body rubber good seal is acted in hydraulic pressure self-tightening.But because door top area is omited
More than bottom area, in the continuous uphill process of water level, buoyancy tank has been in floating state, and the pretightning force of closing the door of door is gradually reduced,
But door-hinge is also accordingly increased by the moment of rolling friction that hydraulic pressure is produced, add weighted spherical ball torque and be conducive to a holding door to close.It is comprehensive
Altogether, before the off-load water level close to setting, the torque of closing the door of door body is slightly larger than enabling torque.
Ordinary water level crosses load water level and is located at following higher than filter cylinder 500 in the following 300mm positions of not higher than filter cylinder ---
550mm positions.When water level is higher than normal work water level 300mm before filter cylinder, the continuation with water level rises, and buoyancy tank is with water level
Float, before off-load water level is reached, upper connecting rod descends pull bar up in idle stroke state relatively, and lower pull bar is motionless, at door body
In closed mode.
When off-load water level of the water level close to setting, and pull bar has been pulled idle stroke and provided a certain amount of by buoyancy tank
Enabling torque, the enabling torque that now all parts are provided and closes the door equalising torque.When water level rises again, hydraulic pressure
And the enabling torque of buoyancy tank etc., greater than torque of closing the door, door is opened.Now proximity switch sends overload-alarm signal.
When buoyancy tank pulling force make the off-load door low-angle of rotate counterclockwise one be opened one stitch after, now counterweight tube synchronous rotary
One low-angle, less than water inlet chamber end, weighted spherical ball rolls to water outlet to the water outlet chamber end of counterweight tube from water inlet chamber end in counterweight tube
Chamber end, the torque disappearance equivalence of closing the door that weighted spherical ball is provided is converted into enabling torque.Because dynamic balance is broken rapidly, door body is complete
Complete to open, as door body is rotated to close to level, hydraulic pressure opposite house has not had moment loading, and now only counter weight device is to door body
There is enabling torque, almost without torque of closing the door, door keeps standard-sized sheet transition.The water of water inlet chamber is endlessly led to up and down by door body
Road flows out to water outlet chamber, the complete off-load of microfroc filter filter cylinder.
When water level decreasing is to slightly above setting normal safe water level 300mm, buoyancy tank spills the water surface completely, and upper connecting rod is with floating
Its idle stroke is depressured under case Gravitative Loads and has followed by depressed pull bar, the driving lever of the Action of Gravity Field of buoyancy tank and pull bar in door-hinge
On, there is provided enough torque of closing the door, enabling torque and rotate door-hinge very little that this torque keeps much larger than above-mentioned weighted spherical ball
Rolling friction mechanical resistance square, door turns clockwise closing.When door is close to closing, the counterweight tube water inlet chamber end of synchronous rotary is less than
Water outlet chamber end, weighted spherical ball is rolled into water chamber end from water outlet chamber end, and power-assisted door body is closed rapidly.Now counterweight tube recovers again
Origin-location provides torque of persistently closing the door for door body, and now proximity switch sends instruction recovery normal condition, so far whole equipment
Initial state has been returned to, one cycle has been completed.
Present example contrast prior art has the following advantages that：
1) fully relying on waterpower due to the present apparatus realizes enabling off-load, and realizes reset of closing the door by gravity, does not have
There are excessive electrical equipment, valve and control component.So as to greatly reducing cost of manufacture and operating cost.
2) because buoyancy and gravity are all very reliable fundamental forces, off-load is timely, action is persistently reliable.
3) convertible off-load door, can provide sufficiently large unloading channel, and water level moment can be allowed to lower.
4) completely built-in structure, it is not necessary to take extra place, greatly reduces the overall floor space of equipment.
5), without electric power, energy-conservation can also play overload protective function under the situation having a power failure.Ensure secondary filter captain
Phase No-mistake Principle runs.
