Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, specifically a high-efficiency sludge dewatering device. Background Technology

[0002] Sludge treatment refers to the process of reducing, stabilizing, and rendering harmless the collected sludge through concentration, conditioning, dewatering, stabilization, drying, or incineration. The main purpose of sludge treatment is to reduce the volume of sludge, minimize its pollution to the environment, and ensure that the treated sludge does not have an adverse impact on the ecological environment. Sludge is also now being used as organic fertilizer, which not only effectively reduces pollution but also allows for waste recycling. After collection, sludge typically has a moisture content of 80%, requiring dewatering equipment to filter it and remove the water, keeping only the sludge. The filtered wastewater needs to undergo further treatment processes.

[0003] In existing sludge treatment dewatering devices, when sludge is discharged into the device, the sludge's viscosity can easily create a vacuum inside, which can affect subsequent extrusion and dewatering processes and reduce the device's dewatering efficiency.

[0004] Therefore, those skilled in the art have provided a highly efficient sludge dewatering device to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a high-efficiency sludge dewatering device. By setting up a movable mechanism, the sludge inside the device can be shaken before being squeezed and dewatered, so that the sludge can be fully dispersed, avoiding the vacuum inside the sludge from affecting the subsequent dewatering process, thereby indirectly improving the device's sludge dewatering efficiency. Secondly, by setting up a pull-out mechanism, the dewatered sludge can be quickly removed from the device for centralized processing, which is very convenient, thus solving the problems mentioned in the background art.

[0008] As a further embodiment of this utility model, the movable mechanism also includes a vertical plate fixedly connected to the upper end of the base of the dehydration device, and the vertical plate and the processing box are connected by multiple spring columns.

[0009] As a further embodiment of this invention, the extrusion plate is located directly above the processing box, and the extrusion plate can be moved into the interior of the processing box to extrude sludge.

[0011] As a further embodiment of this invention, the pull-out mechanism also includes a guide plate fixedly connected to the side wall of the processing box, the guide plate being located below the push bar.

Detailed Implementation

[0020] Please see Figures 1-4 In this embodiment of the present invention, a high-efficiency sludge dewatering device includes a dewatering device base 1, a processing box 2 slidably connected to the upper end of the dewatering device base 1, the interior of the processing box 2 being used for placing and processing sludge, a connecting strip 3 fixedly connected to the rear end of the dewatering device base 1, an electric telescopic rod 4 fixedly connected to the connecting strip 3, and a squeezing plate 5 fixedly connected to the lower end of the electric telescopic rod 4, the squeezing plate 5 being located directly above the processing box 2, and when the electric telescopic rod 4 is working, it can drive the squeezing plate 5 to move downward into the interior of the processing box 2 to squeeze and dewater the sludge.

[0021] The treatment box 2 is fixedly connected to a connecting frame 6, and a filter cloth 7 is set on the connecting frame 6. The filter cloth 7 is used to place sludge. When used with the extrusion plate 5, the sludge can be dewatered. The dewatering device base 1 is provided with a drop port 8. The cleaned water can fall directly from the drop port 8 for collection, which is convenient for centralized treatment of sewage.

[0022] A connecting ring 9 is fixedly connected to the movable part of the electric telescopic rod 4. An L-shaped rod 10 is fixedly connected to the outer wall of the connecting ring 9. A first arc-shaped block 11 is fixedly connected to the L-shaped rod 10. Multiple second arc-shaped blocks 12 of different heights are fixedly connected to the rear end of the treatment box 2. When the connecting ring 9 moves with the electric telescopic rod 4, the first arc-shaped block 11 can be moved by the L-shaped rod 10, thereby pushing the treatment box 2 to move laterally by the second arc-shaped blocks 12. This can shake the sludge inside the treatment box 2, so that it can make full contact and avoid vacuum, which facilitates the subsequent squeezing and dewatering work.

[0023] A vertical plate 13 is fixedly connected to the upper end of the base 1 of the dehydration device. The vertical plate 13 is fixedly connected to the processing box 2 through a spring column 14. When the processing box 2 moves, it can pull the spring column 14. When the first arc block 11 and the second arc block 12 separate, the processing box 2 returns to its original position under the action of the spring column 14, thereby realizing the back-and-forth movement of the processing box 2.

[0024] A cleaning frame 16 is slidably connected to the treatment box 2. A pusher 15 is fixedly connected to the side of the cleaning frame 16 outside the treatment box 2. The cleaning frame 16 can be moved based on the treatment box 2 by the pusher 15, so as to remove the dewatered sludge from the inside of the treatment box 2. A guide plate 17 is fixedly connected to one side of the treatment box 2. The guide plate 17 is located below the pusher 15. The removed sludge can move along the guide plate 17 for convenient subsequent centralized processing.

[0025] The working principle of this utility model is as follows: When sludge needs to be dewatered, the sludge to be dewatered can first be transported to the filter cloth 7 inside the treatment box 2. At this time, the electric telescopic rod 4 is working. When the electric telescopic rod 4 is working, it can drive the extrusion plate 5 to move into the treatment box 2. At this time, the extrusion plate 5 has not yet entered the interior of the treatment box 2. When the electric telescopic rod 4 is working, it can also drive the L-shaped rod 10 to move downward through the connecting ring 9, thereby driving the first arc-shaped block 11 to push the second arc-shaped block 12 and the treatment box 2 to move laterally and pull on the spring column 14. When the first arc-shaped block 11 and the second arc-shaped block 12 are in contact with each other, the L-shaped rod 10 moves downward through the connecting ring 9. This causes the first arc-shaped block 11 to push the second arc-shaped block 12 and the treatment box 2 to move laterally and pull on the spring column 14. When block 12 separates, the processing box 2 returns to its original position under the action of spring column 14, thereby realizing the back-and-forth movement of the processing box 2 and shaking the sludge inside, avoiding the vacuum between the sludge and affecting the subsequent dewatering effect. When the processing box 2 stops moving, the extrusion plate 5 enters the interior of the processing box 2 to extrude and dewater the sludge, improving the dewatering efficiency. After the sludge is dewatered, the cleaning frame 16 can be moved by pushing bar 15, and the dewatered sludge can be taken out. The taken-out sludge can move along guide plate 17 for convenient subsequent centralized processing.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
