Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a dual-station high-pressure sludge dewatering device. Background Technology

[0002] Sludge dewatering equipment is a key piece of equipment in wastewater treatment processes and is widely used in municipal wastewater treatment plants, industrial wastewater treatment stations, and other places. It typically consists of three parts: a cloth feeding and receiving device, a filter cloth that carries the sludge, and a filter press.

[0003] During the filter press operation, the filter cloth is laid in the material basket of the filter press equipment. After the sludge is filtered under high pressure, it forms a filter cake. Due to compression and the action of the filtrate, the filter cloth and the material basket easily become tightly adhered. After filtration, this thin layer creates a large interfacial adhesion force between the filter cloth and the material basket, resulting in a tight bond that is difficult to separate. After filtration, the upper material feeding and unloading equipment needs to retrieve the filter cloth from the material basket. However, because the filter cloth is too tightly adhered to the material basket, forcibly pulling the filter cloth by the feeding and unloading equipment can easily cause damage such as tearing and deformation. This damage usually manifests as tearing at the edges of the filter cloth, partial breakage, or overall tensile deformation. This not only shortens the service life of the filter cloth but also increases the frequency of filter cloth replacement, affecting the continuous operating efficiency of the equipment.

[0004] Currently, existing solutions to this problem mainly involve adding a downward-pressing fixing component to secure the material basket, thereby reducing the pulling resistance during filter cloth recycling. However, this solution requires an additional drive unit to operate the downward-pressing component, increasing the manufacturing cost of the equipment.

[0005] Therefore, how to provide a dual-station high-pressure sludge dewatering equipment is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0015] The beneficial effects of this invention are: This invention improves filtration efficiency by using a dual-station filtration process.

[0016] By using a base plate and a sliding plate that are installed in multiple sections, the cost of processing a single plate is avoided. To prevent the material basket from getting stuck at the joint between the base plate and the sliding plate when it moves, a sliding guide groove is set on the material basket to reduce the risk of getting stuck.

[0017] By using the hydraulic ejector and ejector hole, the cloth and sludge are pushed out of the basket after the filter press is completed. This avoids the problem that the cloth and sludge inside the basket are squeezed too tightly after the water is filtered out, making it difficult to collect the cloth through the cloth collection and discharging equipment, thus improving the discharge efficiency and quality.

[0018] By using the remote and near-end clamping components to fix the material basket, the problem of the material basket being lifted up when the hydraulic jack is used to lift the cloth and sludge is avoided due to excessive pressure between the cloth and sludge and the material basket, thus reducing the risk of damage to the hydraulic jack during translation.

[0019] By fixing the two apex corners of the material basket with the remote clamping assembly, the two apex corners can be fixed efficiently without adding a drive, while ensuring the consistency of the material basket's position when it arrives at the designated location.

Bearings are fitted onto the left and right sides of the connecting rod and fixed to the corresponding positions on the mounting housing 62. Then, install the translation drive mechanism 66 in place. Install the fixing block 661 onto the mounting channel steel 61 according to the preset position, which can be done by welding or bolting. Two sliding rods of the sliding component 662 near one end of the second rack 6621 pass through the fixing block 661. A spring 663 is fitted onto the sliding rods, and the other end is bolted to the two sliding rods of the second rack 6621.

With the bottom firmly attached to the mounting channel steel 61, the mounting housing 62 slides towards the side closer to the material basket 4 until the second rack 6621 meshes with the second gear 642. Before installing the first pressing block 63, the sliding member 662 is moved into the plane of the limiting part 621, so that the spring 663 is compressed. The first pressing block 63 inserts the first rack 631 from the side closer to the material basket 4 until the first rack 631 meshes with the first gear 641. Then, the sliding member 662 is released, and the position of the mounting housing 62 is adjusted left and right so that the second pressing block 623 and the first pressing block 622 can accurately press the corresponding racks and then fix the mounting housing 62.

The near-end pressing basket assembly 7 includes a mounting frame 71, a pressing cylinder 72 and a second pressing basket block 73. The pressing cylinder 72 has a driving end and a telescopic end. The driving end of the pressing cylinder 72 is mounted on the mounting frame 71, and the telescopic end of the pressing cylinder 72 is connected to the second pressing basket block 73.

[0027] Working principle: Referring to the filter press 1 in the figure, following the direction of the components, the left material basket 4 is the first station, the right material basket 4 is the second station, and the bottom plate 2 is the filter pressing station; When the equipment is running, the preceding process feeds the sludge-laden cloth into the material basket 4 at the first station, and the lowering cylinder 72 is in the raised state. The hydraulic station 9 controls the extension of the translation hydraulic top 8 on the side of the first station, and the material basket 4 moves towards the filter press station. During the movement, the translation guide 43 can tilt the bottom of the material basket 4 to pass through positions where the bottom plate 2 may be higher than the push plate 3 through the arc. After the material basket 4 at the first station moves to the filter press station, the hydraulic station 9 controls the filter press 1 to extend downward, and the pressure plate below the filter press 1 extends into the material basket. Inside basket 4, water carried in the cloth and sludge is squeezed out, and the squeezed water flows out from below. After the filtration is completed, the filter press 1 retracts upwards until it is fully retracted. Then, basket 4 on the filter press station is retracted and brought back to the first station by the horizontal hydraulic jack 8. During the continuous movement, the bottom end face of basket 4 near the far end of the basket pressing assembly 6 is attached to the sliding part 662 and continues to retract. During the movement, the second rack 6621 moves away from basket 4, and the spring 663 begins to compress. The movement of the second rack 6621 drives the second gear 642 to rotate. When the connecting rod of the transmission component 64 rotates, it drives the first gear 641 to rotate. The second rack 6621 moves in a direction parallel to and opposite to the first rack 631, that is, the first rack 631 moves towards one side of the material basket 4 until the material basket 4 is against the limiting part 621 and the sliding part 662 is flush with the limiting part 621. The first rack 631 stops moving. At this time, the first rack 631 has extended and pressed against the two top corners of the bottom end of the material basket 4. At the same time, the detection switch 65 detects that the first rack 631 has reached its position and sends a signal. The hydraulic station 9 controls... The hydraulic cylinder 72 extends downwards, the second pressing block 73 presses down on both sides of the material basket 4, the hydraulic station 9 controls the extension of the hydraulic jack 5, the lifting plate 51 lifts the cloth, the cloth receiving and distributing equipment collects the cloth and sludge, and continues to feed new cloth with sludge into the material basket 4 at the first station; at the same time, the cloth receiving and distributing equipment at the second station has already fed cloth with sludge into the material basket 4, and the translation hydraulic jack 8 at the second station pushes the material basket 4 into the filter press station for filter pressing; the material baskets 4 at the two stations operate alternately.
