Description

Technical Field

[0001] The invention relates to a baroclinic electro-osmosis sludge dewatering device. Background Art

[0002] At present, with the continuous growth of annual sludge production in my country, the demand for sludge dehydration is also increasing. Since the moisture content of traditional mechanical dehydration can only be reduced to 80%, while electro-osmosis sludge dehydration can reduce it to 60%.

[0003] Most of the existing electro-osmosis dehydration devices use filter belts, which are prone to clogging. They also require hydraulic devices and vacuum suction devices. The devices are large in size, prone to wear and leakage, and inconvenient to repair and replace. Because some of the existing electro-osmosis sludge dehydration devices use intermittent operation. Its low-voltage power supply is also intermittent operation, requiring hydraulic devices, and the power supply conductive plate has a large area, which is prone to corrosion and scaling, making it inconvenient to repair and replace. The electrode plates used in the existing non-filter belt electro-osmosis dehydration devices are fixed. Due to the presence of large currents, corrosion problems cannot be avoided regardless of whether the electrodes are exchanged regularly or by other means. The maintenance and replacement of fixed electrode plates are complicated, time-consuming and labor-intensive. The existing non-filter belt electro-osmosis dehydration devices use an integral conductive method, which has a long distance for the current to pass, high resistance, and low safety. .

[0036] The working principle of the present invention is as follows: the sludge is evenly distributed on the lower voltage plate by the distribution system, and moves forward together with the upper voltage plate as the motor drives the gear set and the chain. Under the pressure of the pressing device, the upper voltage plate contacts the sludge and exerts pressure on the sludge together with the lower voltage plate; at the same time, the low-voltage power supply is connected to the voltage plate, and an electric field is established inside the sludge, so that part of the bound water inside the sludge is driven out by the electric field. The water released from the sludge flows out from the edge of the lower voltage plate, the water guide groove and the filter seam, falls into the collection device below, and is then discharged to the outside of the device through the pump. During the movement of the voltage plate, its edge pushes the front conductive block of the arc-extinguishing conductive device, and the front conductive block rotates around the center line, so that the front conductive block lever pushes the movable cover plate in the arc-extinguishing switch. After a period of time, the edge of the voltage plate pushes the rear conductive block of the arc-extinguishing conductive device, and the rear conductive block rotates around the center line, so that the rear conductive block lever pushes another movable cover plate in the arc-extinguishing switch. The low-voltage power supply is connected to the arc extinguishing switch through wires. One branch is connected to the resistor and then connected in series to the two pairs of inner and outer reeds and the input end of the relay. The other branch is connected to the output end of the relay. When the two movable covers are pushed by the conductive block at the same time, the two pairs of inner and outer reeds are connected, the relay is energized, and the output end of the relay provides voltage to the rear conductive block through the wire connection. When the voltage plate continues to move forward and its edge leaves the front conductive block, the front conductive block lever leaves the movable cover, separating the inner and outer reeds on one side, disconnecting the circuit, and the relay is powered off, stopping the supply of voltage to the rear conductive block.
