On, the fulcrum 65 of lever mechanism is fixed on the rack, and air spring 66, Ke Yitong is equipped between the promote-side and rack of lever
The inflation/deflation to air spring is crossed, to adjust the motive force to lever, to influence between help roll and lower filter belt drive roll
Pressure.
As shown in fig. 7, upper strainer 47 surround each anode plate, it can be in the upper strainer drive roll 48 and discharging portion of feeder
Cycle rotation between upper strainer driven voller 49, and it is synchronous with the rotation of lower filter belt.Upper strainer is similarly mating to be provided with a set of filter
Band auxiliary strainer, structure are similar to lower filter belt.
In this example, sealing frame 71 is equipped in rack, sealing frame can only be done between lower filter belt and cathode with rack
Lower relative motion.As shown in figure 9, upper strainer and lower filter belt are both provided with the automatic take-up of strainer, including it is outstanding set on upper
Square anode plate lateral edge meets and discusses 72, and corresponding position is provided with meeting switch 73 in rack, and meeting switch is electrically connected lower filter belt
Tensioning cylinder 74 and upper strainer tensioning cylinder 75, lower filter belt tensioning cylinder can push lower filter belt driven voller away from or approaching lower filter belt
Drive roll, upper strainer tensioning cylinder can push strainer driven voller away from or approaching upper strainer drive roll.Upper strainer tensioning cylinder
Expanding-contracting action it is opposite with the expanding-contracting action time synchronization direction of lower filter belt tensioning cylinder.Meeting switch in this example is one two
Five logical machine control valves of position.
In this example, anode plate is pushed by anode plate operating cylinder 81 and is lifted；Anode plate operating cylinder is fixed on oil cylinder installation
On plate 82, oil cylinder mounting plate is located above anode plate；Oil cylinder mounting plate is pushed by anode plate lifting cylinder 83 and is lifted.Anode plate liter
The work drive motor power of drop oil cylinder is less than the work drive motor of anode plate operating cylinder.When needing lifting cylinder mounting plate, only
It needs to start low power motor, using anode plate lifting cylinder, only when needing to carry out press dewatering operation, just open
Dynamic heavy-duty motor, uses anode plate operating cylinder.
A kind of cathode of this example can the electric energy dewaterer of automatic desludging pass through hopper under the opening, charging in the cloth stage
Pump selects screw feed pump, ensure that charging is not influenced by gravitation, and it is uniform that charging may be implemented.The drive motor of feed pump is to become
Frequency motor can be such that charging rate is matched with the gait of march of lower filter belt, i.e., with the dewatering operation speed of electric energy de-watering section
Match.The twin distributing device that distributing device is selected, cloth effect is evenly.Lower filter belt is loose under the water smoking, normality, is contained
Corner after full with substance under the effect of gravity with sealing frame fits closely.When upper anode plate downlink, meet and discuss and nozzle switch
Contact generates electric signal, so that strainer is tensioned under the action of upper strainer tensioning cylinder, anode plate lower surface fits closely material
Upper surface pushes sealing frame and lower filter belt to come downwards to lower filter belt close adhesion plate chain belt, and then cathode anode is powered on one side, anode plate one
While continuing to push, using electronic and mechanical double action, the liquid in material is squeezed out.Dehydration finishes, anode plate uplink, then
Secondary to generate electric signal by meeting switch, lower filter belt is tensioned under the action of lower filter belt tensioning cylinder at this time, and upper strainer relaxes,
Lower filter belt is set to may carry the material that has been dehydrated to discharging end motion.It, can be under due to being provided with help roll in discharge end
Strainer drive roll is bonded and free to rotate, and lower filter belt is compressed therebetween, lower filter belt beating during exercise can be prevented
Sliding phenomenon.Upper strainer also uses same structure.About plate chain belt, plate chain belt is fixed when dewatering operation, is only existed
Dewatering operation for a period of time, chain plate surface generate apparent fouling when, just need scale removal operation.When scale removal, lower filter belt is not necessarily to action,
Plate chain is independent to be rotated forward, and when by cleaning section position, chain plate surface is scrubbed by Steel wire roll brush, is rushed by high-pressure spray gun
It washes, fouling is eliminated.The entire scale removal time only needs ten rather to plant.About the action of anode plate, as a result of two sets of oil
Cylinder system, manages the squeezing action of the lifting action and anode plate of oil cylinder mounting plate respectively, therefore can lift oil in anode plate
The smaller motor of power is used on cylinder, with energy saving.Entire dewaterer is controlled by PLC controller, both can be according to default journey
Sequence moves automatically, can also locally carry out manual intervention operation, realize high-efficient homework.
