Description

Technical Field

[0001] This utility model relates to the field of sludge thickening tank technology, specifically a modular stacked sludge thickening tank. Background Technology

[0002] In wastewater treatment, multi-stage sedimentation tanks are needed to separate the solids and liquids of the wastewater. This allows sludge to separate from the water under gravity, with the sludge settling to the bottom and the wastewater floating on top. The settled sludge can be discharged through a sludge removal device, allowing for further wastewater sedimentation treatment. The sludge in the sedimentation tanks also needs to undergo sedimentation and concentration treatment to ensure effective sedimentation before being effectively discharged.

[0003] Existing sludge thickening tanks are just single sludge hoppers and cannot be stacked in multiple layers, making them unsuitable for wastewater treatment scenarios of different scales. In addition, the sludge discharge operation of existing sludge thickening tanks cannot be adjusted automatically according to actual needs, affecting the sludge discharge effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a modular stacked sludge thickening tank. By setting up a sedimentation tank, sludge hopper and inclined plate, the sludge hopper can be stacked in a cross shape, thereby adapting to different scales of sewage treatment scenarios and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular stacked sludge thickening tank, including a sedimentation tank, wherein sludge hoppers are stacked on the inner side of the sedimentation tank, a sludge discharge pipe is connected to the lower side of the lowest sludge hopper, and arc-shaped baffles are symmetrically arranged on the lower side of the sludge discharge pipe. Toothed discs are arranged on the upper part of both ends of the arc-shaped baffles, and a hydraulic cylinder is connected to the center of the side edge of one side of the arc-shaped baffle. A PLC control module is installed on the outer side of the sedimentation tank.

[0006] Furthermore, an inclined plate is connected to the lower edge of the sedimentation tank, and the inclined plate is fixedly connected to the sludge hopper at the bottom.

[0007] Furthermore, four support columns are provided on the lower side of the sedimentation tank, and a conveyor belt is provided at the bottom of the sludge discharge pipe.

[0008] Furthermore, the toothed disc is fixedly connected to the arc-shaped baffle, the two toothed discs mesh with each other, and the upper end of the arc-shaped baffle is connected to the mud discharge pipe through a bearing.

[0009] Furthermore, the lower end of the hydraulic cylinder is hinged to the arc-shaped baffle, and the upper end of the hydraulic cylinder is hinged to the outer side of the sludge hopper.

[0010] Furthermore, the sludge hoppers are arranged in staggered layers inside the sedimentation tank, and the interior of the sludge hoppers has an inverted trapezoidal structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of sedimentation tank, sludge hopper and inclined plate, allows the sludge hopper to be stacked in a cross shape, thereby adapting to different scales of sewage treatment scenarios.

[0012] 2. This utility model uses a PLC control module, hydraulic cylinder, arc-shaped baffle, and gear plate to enable the hydraulic cylinder to drive the arc-shaped baffle on one side to rotate, and the gear plate to drive the arc-shaped baffle on the other side to rotate synchronously. This allows the two arc-shaped baffles to be opened or closed simultaneously, so that the sludge in the sludge hopper at the bottom can be discharged downward through the sludge discharge pipe. The adjustment can be made according to actual needs to meet the sludge discharge effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4This embodiment provides a technical solution: a modular stacked sludge thickening tank, including a sedimentation tank 1, with sludge hoppers 3 stacked inside the sedimentation tank 1, a sludge discharge pipe 8 connected to the lower side of the lowest sludge hopper 3, and arc-shaped baffles 7 symmetrically arranged on the lower side of the sludge discharge pipe 8. Toothed discs 9 are arranged on the upper part of both ends of the arc-shaped baffles 7, and a hydraulic cylinder 6 is connected to the center of the side edge of one side of the arc-shaped baffle 7. A PLC control module 10 is installed on the outer side of the sedimentation tank 1.

[0017] like Figures 1-4 As shown, after the sewage enters the sedimentation tank 1, the sludge and water separate under the action of gravity, and the sludge settles into the sludge hopper 3. Depending on the sewage conditions, multiple layers of sludge hoppers 3 are set inside the sedimentation tank 1, so that the sludge hoppers 3 are stacked. The bottom layer of sludge hopper 3 is provided with two arc-shaped baffles 7. When sludge needs to be discharged, the hydraulic cylinder 6 drives one arc-shaped baffle 7 to rotate, and drives the other arc-shaped baffle 7 to rotate through the gear plate 9. This can open or close the two arc-shaped baffles 7, so that the sludge inside the bottom layer of sludge hopper 3 is discharged from the sludge discharge pipe 8 and then falls onto the conveyor belt 5, so that the conveyor belt 5 can transport the sludge away.

[0018] An inclined plate 4 is connected to the lower edge of the sedimentation tank 1, and the inclined plate 4 is fixedly connected to the sludge hopper 3 at the bottom.

[0019] Four support columns 2 are installed on the lower side of the sedimentation tank 1, and a conveyor belt 5 is installed below the bottom sludge discharge pipe 8.

[0020] The toothed disc 9 is fixedly connected to the arc-shaped baffle 7, and the two toothed discs 9 mesh with each other. The upper end of the arc-shaped baffle 7 is connected to the mud discharge pipe 8 through a bearing.

[0021] The lower end of the hydraulic cylinder 6 is hinged to the arc-shaped baffle 7, and the upper end of the hydraulic cylinder 6 is hinged to the outer side of the sludge hopper 3.

[0022] The sludge hopper 3 is arranged in staggered layers inside the sedimentation tank 1, and the interior of the sludge hopper 3 has an inverted trapezoidal structure.

[0023] The working principle of the modular multilayer sludge thickener provided by this utility model is as follows: Figures 1-4 As shown, after the sewage enters the sedimentation tank 1, the sludge and water separate under the action of gravity, and the sludge settles into the sludge hopper 3. Depending on the sewage conditions, multiple layers of sludge hoppers 3 are set inside the sedimentation tank 1, so that the sludge hoppers 3 are stacked. The bottom layer of sludge hopper 3 is provided with two arc-shaped baffles 7. When sludge needs to be discharged, the hydraulic cylinder 6 drives one arc-shaped baffle 7 to rotate, and drives the other arc-shaped baffle 7 to rotate through the gear plate 9. This can open or close the two arc-shaped baffles 7, so that the sludge inside the bottom layer of sludge hopper 3 is discharged from the sludge discharge pipe 8 and then falls onto the conveyor belt 5, so that the conveyor belt 5 can transport the sludge away.
