Description

Technical Field

[0001] This utility model relates to the technical field of sludge dewatering devices, and in particular to an energy-saving sedimentation tank sludge dewatering device. Background Technology

[0002] Sludge dewatering equipment refers to equipment used to remove water from sludge. It is widely used in wastewater treatment processes in industries such as urban sewage treatment plants, pharmaceuticals, electroplating, papermaking, leather, printing and dyeing, metallurgy, and chemicals. It is an important piece of equipment for environmental governance and resource recycling. An energy-saving sedimentation tank sludge dewatering device is a device specifically designed for sludge dewatering in sedimentation tanks, aiming to improve the efficiency of sludge dewatering and realize the recycling of resources.

[0003] To address this issue, patent CN209865519U discloses a sludge dewatering device, belonging to the field of sludge pretreatment technology. It solves the problem that existing sludge pretreatment devices cannot effectively separate water from sludge. This sludge dewatering device includes a chamber with an inner cavity. A sludge-water inlet and outlet are located on the side of the chamber, situated on opposite sides with the inlet higher than the outlet. A partition plate divides the inner cavity into an upper and lower cavity. The partition plate is inclined, with its upper end located on the side of the chamber with the sludge-water inlet. A through-hole connects the upper and lower cavities, containing a filter assembly. A power unit drives the partition plate to move up and down. This invention offers advantages such as good separation effect and high efficiency.

[0004] The sludge dewatering device described above uses a partition plate to squeeze the sludge during use, thereby squeezing out the water from the sludge. However, the partition plate is set at an angle, which prevents the sludge at the bottom from being completely squeezed out during the squeezing process, resulting in a high water content in the sludge and a reduced solids content.

[0011] Preferably, one end of the first rotating shaft extends through one side of the filter cylinder to the outside of the filter cylinder and is fixedly connected to the output end of the first motor; the bottom end of the water outlet extends through the inside of the support plate to the inside of the water collection tank; and one end of the water inlet pipe extends through one side of the tank body to the inside of the tank body.

[0012] With the above structure, water can enter the water collection tank through the outlet and be collected inside the tank through the inlet pipe, thus realizing the utilization of water resources.

[0013] Preferably, the filter plate and the support plate are slidably connected by a fixed groove, the filter plate is L-shaped, and the length of the filter plate is the same as the length of the reserved groove.

[0014] The above structure facilitates the installation and disassembly of the filter plate during use, makes it easy to clean, and prevents impurities from clogging the filter holes and reducing the filtration effect.

[0015] Preferably, both ends of the roller are provided with openings, one end of the filter cylinder extends through one side of the box body into the inside of the box body and forms a rotatable connection with the inside of the roller, the inside of the roller is connected to the inside of the filter cylinder, and one end of the first rotating shaft extends through one end of the roller into the inside of the roller and is fixedly connected to one end of the second rotating shaft.

[0016] With the above structure, during use, the sludge is pushed into the inside of the drum by the action of the first spiral blade, and the rotation of the first rotating shaft drives the second rotating shaft to rotate, thereby causing the second spiral blade to further screw press the sludge, thus improving the solids content of the sludge.

[0017] Preferably, the roller is rotatably connected inside the support ring, the filter screen is symmetrically distributed on the outside of the roller, and the driven gear is meshed with the driving gear.

[0019] Preferably, one end of the discharge pipe extends through one side of the box body into the interior of the drum and forms a rotatable connection with the interior of the drum, and the end cap is fixedly connected to the discharge pipe by threads.

[0020] With the above structure, when in use, the end cover is opened, allowing the sludge to be discharged outward through the discharge pipe under the action of the second spiral blades, thus facilitating material discharge.

[0021] The present invention provides an energy-saving sludge dewatering device for sedimentation tanks, the advantages of which are:

[0022] By setting up a filtration structure, sludge is fed into the filter cylinder through the feed hopper. As the first spiral blade rotates, the sludge is squeezed by the spiral, which effectively separates the water and solids in the sludge. The solids are then effectively separated by the filter plate, and the water enters the water collection tank through the outlet and is collected inside the tank through the inlet pipe, thus realizing the utilization of water resources.

[0023] By incorporating a rotating structure, the rotation of the drum causes the water inside the sludge to be thrown outward from the inside of the filter screen under centrifugal force, thereby further removing water from the sludge. The rotation of the second spiral blades further screws and presses the sludge, increasing the solids content of the sludge. This allows the flowing water to be discharged outward through the drain pipe, which is beneficial for water resource recycling. At the same time, the sludge is discharged outward through the discharge pipe under the action of the second spiral blades, thus facilitating material discharge. Attached Figure Description

[0031] Please see Figure 1-5 The present invention provides an energy-saving sedimentation tank sludge dewatering device, which includes a box body 1 and a rotating structure 5.

[0032] Reference Figures 1-3As shown, a support plate 2 is fixed to one side of the housing 1, a support leg 3 is fixed to one side of the bottom of the support plate 2, and a filter structure 4 is fixed to the top of the support plate 2. The filter structure 4 includes a filter cylinder 401 fixed to the top of the support plate 2, a feed hopper 402 fixed to one side of the top of the filter cylinder 401, a first motor 403 fixed to one end of the filter cylinder 401, a first rotating shaft 404 installed inside the filter cylinder 401, a first spiral blade 405 fixed to the outside of the first rotating shaft 404, a water outlet 406 provided on the other side of the bottom of the filter cylinder 401, a water collection tank 407 fixed to the bottom of the housing 1, a water inlet pipe 408 fixed to one side of the bottom of the water collection tank 407, and the support plates 2 on both sides of the water outlet 406.

The bottom end of the water outlet 406 extends through the inside of the support plate 2 to the inside of the water collection tank 407. One end of the water inlet pipe 408 extends through one side of the tank 1 to the inside of the tank 1. The filter plate 410 and the support plate 2 are slidably connected through the fixing groove 409. The filter plate 410 is L-shaped and its length is the same as the length of the reserved groove 411.

[0033] Sludge is fed into the filter cylinder 401 through the feed hopper 402. The first motor 403 drives the first rotating shaft 404 to rotate the first spiral blade 405. During the rotation of the first spiral blade 405, the sludge is squeezed by the spiral, effectively separating the water and solids in the sludge. The filter plate 410 is installed from the reserved groove 411 and then moved into the fixed groove 409 to fix the filter plate 410. This also facilitates the disassembly and cleaning of the filter plate 410, preventing impurities from clogging the filter holes and reducing the filtration effect. The filter plate 410 effectively separates the solids, allowing water to enter the water collection tank 407 through the outlet 406 and then enter the tank body 1 through the inlet pipe 408 for collection, thus realizing the utilization of water resources.

[0034] Reference Figure 2 , Figure 4 and Figure 5As shown, a rotating structure 5 is installed inside the housing 1. The rotating structure 5 includes a support ring 501 fixed inside the housing 1, a roller 502 rotatably connected inside the support ring 501, filter screens 503 fixed on both sides of the roller 502, a second rotating shaft 504 installed inside the roller 502, a second spiral blade 505 fixed on the outside of the second rotating shaft 504, a discharge pipe 506 fixed on one side of the housing 1, an end cap 507 installed on the outside of the discharge pipe 506, a driven gear 508 fixed on one end of the outside of the roller 502, a driving gear 509 installed on one side of the driven gear 508, a third rotating shaft 510 fixed on one end of the driving gear 509, a second motor 511 fixed on one end of the third rotating shaft 510 on the outside of the housing 1, a drain pipe 512 fixed on one side of the bottom of the housing 1, and the roller 502... Both ends of 2 are provided with openings. One end of the filter cylinder 401 extends through one side of the box body 1 into the interior of the box body 1 and is rotatably connected to the interior of the roller 502. The interior of the roller 502 is connected to the interior of the filter cylinder 401. One end of the first rotating shaft 404 extends through one end of the roller 502 into the interior of the roller 502 and is fixedly connected to one end of the second rotating shaft 504. The roller 502 is rotatably connected inside the support ring 501. The filter screen 503 is symmetrically distributed on the outside of the roller 502.

The end cover 507 is fixedly connected to the discharge pipe 506 by threads. A box door 6 is installed on one side of the box body 1.

[0035] The sludge is pushed into the drum 502 by the first spiral blade 405. Then, the second motor 511 drives the third shaft 510, causing the drive gear 509 to rotate. The drive gear 509 meshes with the driven gear 508, causing the drum 502 to rotate. This rotation within the support ring 501 ensures the stability of the drum 502 during rotation. Furthermore, the rotation of the drum 502 causes water inside the sludge to be centrifuged and expelled through the filter screen 503. The sludge is thrown outward from its interior, further removing moisture from the sludge. The rotation of the first rotating shaft 404 drives the second rotating shaft 504 to rotate, which in turn drives the second spiral blades 505 to rotate, further pressing the sludge and increasing its solids content. This allows the flowing water to be discharged through the drain pipe 512, which is beneficial for water resource recycling. At the same time, by opening the end cover 507, the sludge is discharged through the discharge pipe 506 under the action of the second spiral blades 505, thus facilitating material discharge.
