Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a sludge sedimentation device that is easy to clean. Background Technology

[0002] In related technologies, common sewage sedimentation equipment is usually divided into three stages: the first stage collects sewage and wastewater, the second stage allows for static sedimentation, and the third stage collects and discharges clean water. These technologies typically divide a single device into three spaces in a stepped manner. When cleaning the sedimentation equipment, workers need to enter and exit these three spaces multiple times, which reduces the cleaning efficiency of the sewage sedimentation equipment. Furthermore, the sludge generated during the cleaning process is difficult to handle and needs to be shoveled out by workers, increasing their labor intensity. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides an easy-to-clean sludge sedimentation device. This easy-to-clean sludge sedimentation device can easily and quickly clean the sediment in the collection tank, sedimentation tank, and clear water tank. Cleaning workers can clean the bottom and walls of the tank in one go without having to enter and exit the tank multiple times to clean different areas, thus improving cleaning efficiency and reducing cleaning labor intensity.

[0023] To address the aforementioned issues, this application provides a sludge sedimentation device that is easy to clean.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the structure of a sludge sedimentation device that is easy to clean, as shown in the embodiments of this application.

[0026] See Figure 1 The sludge sedimentation device for easy cleaning shown in Embodiment 1 of this application includes a water collection tank 1, a sedimentation tank 2, and a clear water tank 3. A rotatable first gate 4 is installed between the water collection tank 1 and the sedimentation tank 2, and a rotatable second gate 5 is installed between the sedimentation tank 2 and the clear water tank 3. After the first gate 4 and the second gate 5 are closed, they are locked by a locking device 6 and sealed. When the sludge settling device is working normally and settling sludge, the first gate 4 and the second gate 5 are locked by the locking device 6, and an effective seal is achieved by setting elastic rubber 26 on the first gate 4 and the second gate 5. When it is necessary to clean the collection tank 1, the settling tank 2, and the clear water tank 3, the locking device 6 is first opened, so that the first gate 4 and the second gate 5 are opened. The staff first enters the clear water tank 3 to clean the sludge that is blocking the rotation of the second gate 5. Then the second gate 5 is fully opened. Next, the sludge that is blocking the rotation of the first gate 4 in the settling tank 2 is cleaned. Then the first gate 4 is fully opened. Then the collection tank 1, the settling tank 2, and the clear water tank 3 are cleaned in sequence. This can effectively reduce the number of times the staff have to enter and exit the sludge settling device and can clean the collection tank 1. The sedimentation tank 2 and clear water tank 3 are cleaned in one go, which speeds up the cleaning efficiency of the staff and reduces the labor intensity of the staff. The first gate 4 and the second gate 5 are equipped with the first drainage trough 12 and the second drainage trough 13 in sequence. The first drainage trough 12 is higher than the second drainage trough 13, so that the sedimentation tank 2 can effectively settle sludge, and the settled clear water can automatically flow into the clear water tank 3. The collection tank 1 is equipped with an inlet pipe 14 that extends to the bottom, so that the sewage can be mixed in the collection tank 1 and avoid sedimentation in the collection tank 1. The bottom of the clear water tank 3 is equipped with a drain pipe 15 and a cleaning pipe 16. The diameter of the drain pipe 15 is smaller than that of the cleaning pipe 16, and the diameter of the cleaning pipe 16 is larger to facilitate the discharge of sludge and avoid the staff having to shovel out the sediment, thereby reducing the labor intensity of the staff.

[0027] The locking device 6 shown in Embodiment 2 of this application includes a screw 7, a nut 8, a positioning plate 9, and an ear plate 10. The screw 7 is installed on the first gate 4 and the second gate 5 through the ear plate 10. The upper end of the water collection tank 1 and the sedimentation tank 2 are both equipped with positioning plates 9. The positioning plates 9 are provided with slots 11. The screw 7 extends into the slots 11 and is fixed by the nut 8. The screw 7 is rotatably installed on the ear plate 10, making it easier for the screw 7 to be inserted into the slots 11.

[0028] In Embodiment 3 of this application, the bottom heights of the water collection tank 1, sedimentation tank 2, and clear water tank 3 decrease sequentially, while the widths of the side walls increase sequentially. The decrease in bottom height of the water collection tank 1, sedimentation tank 2, and clear water tank 3 effectively improves cleaning efficiency during equipment cleaning. The bottom forms a first-level step 17 and a second-level step 18, respectively, and the side walls form a first-level support platform 19 and a second-level support platform 20, respectively. A first gate 4 is installed at the connection between the water collection tank 1 and the sedimentation tank 2, and it can be sealed when it is in contact with the first-level step 17 and the first-level support platform 19 to prevent the water collection tank 1 and the sedimentation tank 2 from mixing, which would result in poor sedimentation. A second gate 5 is installed at the connection between the sedimentation tank 2 and the clear water tank 3, and it can be sealed when it is in contact with the second-level step 18 and the second-level support platform 20.

[0029] In Embodiment 4 of this application, the first gate 4 and the second gate 5 are both provided with grooves 21 at their bottoms and rotating shafts 22 at their tops. The sedimentation tank 2 and the clear water tank 3 are both provided with support shafts 23 at their bottoms. The first gate 4 and the second gate 5 are rotatably installed in the sedimentation tank 2 and the clear water tank 3 respectively through the grooves 21 and the support shafts 23. Support plates 24 are installed on the upper walls of the sedimentation tank 2 and the clear water tank 3. The lower end face of the support plates 24 is provided with mounting grooves. The rotating shafts 22 at the top of the first gate 4 and the second gate 5 are installed in conjunction with the corresponding mounting grooves, which makes the installation of the first gate 4 and the second gate 5 simple and convenient for rotation.

[0030] An arc-shaped buffer plate 25 is provided on the first gate 4 at the lower end of the first drainage channel 12 shown in Embodiment 4 of this application to buffer the flow of sewage and reduce the amount of sewage in the collection tank 1 entering the sedimentation tank 2 and stirring up sludge.

[0031] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
