Description

Technical Field

[0001] This utility model relates to the field of sewage treatment, specifically a sewage treatment pond dredging device. Background Technology

[0002] Wastewater treatment refers to the process of removing, transforming, or degrading pollutants in wastewater through physical, chemical, and biological methods to bring it up to certain water quality standards, thereby purifying and reusing wastewater and reducing environmental pollution. Wastewater treatment ponds are structures used to achieve different treatment functions in the wastewater treatment process. During long-term operation, wastewater treatment ponds accumulate a large amount of sludge and debris. If this sludge is not cleaned in time, it will affect the wastewater treatment effect and may even lead to equipment blockage and damage.

[0003] Traditional sludge removal devices often result in densely packed sludge that is difficult to extract and clean directly, leading to low sludge removal efficiency. Although some devices have a mixing function, their complex structure and inconvenient operation, as well as the inability to flexibly adjust the mixing depth and range, make them difficult to adapt to the sludge removal needs of different depths and complex environments, resulting in poor mixing effects and an inability to effectively disperse the sludge. Therefore, a sludge removal device for sewage treatment ponds is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a sludge removal device for a sewage treatment pond. The device includes a support frame 1, casters 2 at the bottom of the support frame 1, a moving device 3 inside the support frame 1, a mounting frame 4 fixedly connected to the outside of the moving device 3, a protective frame 5 fixedly connected to the inside of the mounting frame 4 by fasteners, a rotating device 6 inside the protective frame 5, a first rotating shaft 7 fixedly connected to the inside of the rotating device 6 and rotatably connected to the inside of the protective frame 5, two first stirring frames 8 symmetrically distributed on the left and right sides fixedly connected to the outside of the first rotating shaft 7, a second rotating shaft 9 fixedly connected to the outside of the protective frame 5 and fixedly connected to the rotating device 6, and a second stirring frame 10 fixedly connected to the outside of the second rotating shaft 9.

[0028] The moving device 3 includes a first motor 31 fixedly connected to the outside of the support frame 1. The output shaft of the first motor 31 is fixedly connected to a threaded rod 32 rotatably connected to the inside of the support frame 1. The outside of the threaded rod 32 is connected to a transmission block 33 fixedly connected to the mounting frame 4.

[0029] In this embodiment, during actual use, in the process of dredging the sewage treatment tank, by controlling the forward and reverse rotation of the first motor 31, the threaded rod 32 can be rotated, and then the position of the mounting frame 4 can be moved under the movement of the transmission block 33, so that the two sets of mixing frames can reach the sludge in different positions and carry out a more comprehensive dredging operation.

[0030] The support frame 1 has two sliding rods 11 fixedly connected inside, and the mounting frame 4 has sliding sleeves 12 fixedly connected to the two sliding rods 11 respectively.

[0031] In this embodiment, during actual use, the two sets of mixing racks need to perform mixing operations at different positions during the dredging process. The structure of the sliding rod 11 and the sliding sleeve 12 can ensure that the mixing rack remains stable during movement, avoiding poor mixing effect or damage to the pool wall due to shaking. At the same time, the outer sides of the sliding rod 11 and the threaded rod 32 are equipped with dustproof telescopic protective sleeves, which can effectively prevent foreign objects such as dust, oil, and water from entering their interiors, thus protecting them.

[0032] The rotating device 6 includes a second motor 61 fixedly connected to the outside of the protective frame 5. The output shaft of the second motor 61 is fixedly connected to a worm gear 62 rotatably connected to the inside of the protective frame 5. The outside of the first rotating shaft 7 is fixedly connected to a worm wheel 63 that meshes with the worm gear 62.

[0033] In this embodiment, during actual use, the rotation of the second motor 61 during the dredging process enables the worm gear 62 to rotate, which in turn causes the worm wheel 63 and its internal first stirring frame 8 to rotate, stirring the sludge to loosen it and facilitate subsequent removal. This structure can effectively improve dredging efficiency, especially when the sludge is relatively viscous. The rotation of the first stirring frame can better break down the structure of the sludge, making it easier to remove.

[0034] The second rotating shaft 9 is fixedly connected to the outer side of the worm gear 62, and the first rotating shaft 7 passes through and extends to the outer side of the protective frame 5.

[0035] In this embodiment, during actual use, the fixed connection between the second rotating shaft 9 and the worm gear 62 enables the second stirring frame 10 to rotate with the first stirring frame 8, thereby enhancing the stirring effect. At the same time, the design of the first rotating shaft 7 extending through to the outside of the protective frame facilitates the outward extension of the first stirring frame 8 to achieve the stirring effect of the first stirring frame 8.

[0036] The protective frame 5 has multiple threaded holes distributed vertically inside, and the mounting bracket 4 has bolts that are threadedly connected to the threaded holes inside.

[0037] In this embodiment, during actual use, appropriate threaded holes can be selected for installation according to the specific size of the sewage treatment tank and the dredging requirements, ensuring the installation height of the device protective frame 5, improving the stability and adaptability of the device. In addition, the bolt connection method facilitates disassembly and maintenance, reducing the maintenance cost of the device.

[0038] Working principle:

[0039] The sewage treatment tank sludge removal device is moved above the sewage treatment tank. The position of the device is adjusted using casters 2 to align it with the area requiring sludge removal. Casters 2 are self-locking casters for easy movement and stopping. Normally, the device is positioned near the sludge suction pipe to disperse the sludge. The device can also be manually or mechanically moved to change the sludge dispersion position. Subsequently, the first motor 31 is started, and its output shaft drives the threaded rod 32 to rotate. The rotation of the threaded rod 32 causes the transmission block 33 to move left and right along the threaded rod, thereby moving the mounting frame 4 left and right. During movement, the mounting frame 4 slides on the sliding rod 11 via the sliding sleeve 12, ensuring stability and guidance. The protective frame 5 needs to be installed before sludge removal, and is installed according to the height of the sludge removal tank. The installation positions of the two sets of mixers are changed within the threaded hole, allowing the first mixing frame 8 and the second mixing frame 10 to reach the silt layer that needs to be dredged. The second motor 61 is started, and the output shaft of the second motor drives the worm gear 62 to rotate. The rotation of the worm gear 62, through meshing with the worm wheel 63, drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 causes the first mixing frame 8 to rotate, stirring the silt. At the same time, the second rotating shaft 9 is fixedly connected to the worm gear 62, driving the second mixing frame 10 to rotate synchronously, further enhancing the stirring effect. During the rotation of the mixing frame, the silt is loosened and stirred evenly, making it easier for subsequent suction equipment to remove. According to the dredging progress, the mounting frame 4 is gradually moved by controlling the forward and reverse rotation of the first motor 31, so that the two sets of mixing frames are moved to a new position to continue the dredging operation.
