Description

Technical Field

[0001] This utility model belongs to the field of industrial wastewater treatment technology, and specifically relates to a circulating filtration device for wastewater treatment. Background Technology

[0002] If industrial wastewater is discharged directly without treatment, it will seriously affect the water function of surface water and groundwater, leading to water quality deterioration. Harmful substances in the wastewater may damage aquatic organisms and ecosystems, thereby affecting ecological balance and biodiversity. Therefore, filtration devices are needed for wastewater recycling.

[0003] For example, Chinese Patent No. CN219239444U discloses an industrial wastewater treatment and recycling device, which relates to the field of industrial wastewater treatment technology. It includes a preliminary filtration device and a dilution mechanism. The dilution mechanism is provided on the right side of the preliminary filtration device. The preliminary filtration device includes a device base, a device shell, a water inlet, a first dosing port, a stirring motor, a stirring pile, a filter screen, a first water outlet, a water pump, a connecting pipe, a sedimentation bin, a solenoid valve, a water volume observation window, and a sedimentation observation window.

[0004] The aforementioned patent addresses the issues of the inability to quickly induce a reaction between the drug and water, and the inability to monitor the reaction of the wastewater during the reaction process. However, some shortcomings remain that require improvement. Specifically, because the mixing pile remains static within the tank, sufficient dynamic mixing is not achieved, resulting in uneven mixing between the drug and wastewater and an unsatisfactory mixing effect. Furthermore, the currently used filter screen is directly fixed inside the tank. This design not only makes the removal and replacement of the filter screen cumbersome and inconvenient for maintenance, but also, if a sliding groove is added to install the filter screen, it is prone to leakage, thus affecting the stability and efficiency of the entire wastewater treatment system.

[0023] Example

[0024] refer to Figures 1 to 6 The wastewater treatment circulating filtration device described in this embodiment includes a first tank 1 and a second tank 2. Both the first tank 1 and the second tank 2 are equipped with dosing pipes for adding chemicals. The second tank 2 is also equipped with a wastewater discharge pipe for discharging purified wastewater. A water supply pipe 4 is fixedly connected between the first tank 1 and the second tank 2. A water pump 3 is installed on one side of the water supply pipe 4. A first fixing frame 6 is fixedly connected to one side of the first tank 1. A first driving assembly 7 is installed on one side of the first fixing frame 6. A filter screen 5 is slidably connected inside the first tank 1 through the first driving assembly 7. A second drive assembly 10 is provided on one side of the first drive assembly 7. A second fixed frame 12 is rotatably connected to the first housing 1 through the second drive assembly 10. A third drive assembly 11 is provided on one side of the second fixed frame 12. A stirring pile 13 is slidably connected to one side of the second fixed frame 12 through the third drive assembly 11. The stirring pile 13 is located inside the first housing 1. Through the above improvements, the mixing effect between the drug and the wastewater can be significantly improved, ensuring a more complete reaction and improving the efficiency and quality of wastewater treatment. In addition, the filter screen 5 is easy to remove and replace, which can reduce the difficulty and time cost of maintenance work.

[0025] refer to Figure 2 The filter screen 5 has grooves 51 on both sides of its top end, and a gantry frame 52 is rotatably connected inside the grooves 51. By setting the grooves 51 and the gantry frame 52, it is convenient for workers to remove the filter screen 5 with the help of the gantry frame 52, which provides convenience for maintenance personnel.

[0026] refer to Figure 4-5 The first drive assembly 7 includes a first motor 71, which is fixedly connected to a first fixed frame 6. A first lead screw 74 is rotatably connected to the first fixed frame 6 via the first motor 71. An L-shaped connecting rod 75 is threaded onto the outer surface of the first lead screw 74. The filter screen 5 is installed at the bottom of the L-shaped connecting rod 75. A first driving gear 72 is fixedly connected to the output end of the first motor 71. A first driven gear 73 is meshed with one side of the first driving gear 72. The first driven gear 73 is fixedly connected to the first lead screw 74. By setting the first drive assembly 7, the first motor 71 drives the first driving gear 72 to rotate, the first driving gear 72 drives the first driven gear 73 to rotate, and the first driven gear 73 drives the first lead screw 74 to rotate, causing the L-shaped connecting rod 75 on its surface to move. The L-shaped connecting rod 75 drives the filter screen 5 to move, allowing the filter screen 5 to extend out of the first housing 1 for easy maintenance by maintenance personnel.

[0027] refer to Figure 5 The L-shaped connecting rod 75 has a dovetail groove 8 inside, and a dovetail slider 9 is slidably connected inside the dovetail groove 8. The bottom end of the dovetail slider 9 is fixedly connected to the top end of the filter screen 5. The dovetail slider 9 is fixedly connected to the dovetail groove 8 by screws. By setting the dovetail slider 9 and the dovetail groove 8, after the screws are removed, the dovetail slider 9 and the dovetail groove 8 are no longer fixed. The filter screen 5 can be pulled to separate the two. Since the dovetail slider 9 and the dovetail groove 8 are T-shaped structures, the filter screen 5 will not fall downwards after the screws are removed. It can only be pulled horizontally to remove it.

[0028] refer to Figure 1 and Figure 6 The second drive assembly 10 includes a second motor 101, which is fixedly connected to one side of the first housing 1. A second drive gear 102 is fixedly connected to the output end of the second motor 101. A second driven gear 103 is meshed with one side of the second drive gear 102. A shaft 104 is fixedly connected to one side of the second driven gear 103. One end of the shaft 104 extending into the first housing 1 is fixedly connected to the second fixed frame 12. By setting the second drive assembly 10, the second motor 101 drives the second drive gear 102 to rotate, and the second drive gear 102 drives the second driven gear 103 to rotate, thereby causing the shaft 104 to drive the second fixed frame 12 to rotate, and causing the second fixed frame 12 to drive the mixing pile 13 to rotate to mix the wastewater and the chemical solution.

[0029] refer to Figure 3 and Figure 6 The third drive assembly 11 includes a third motor 111, which is fixedly connected to one side of the second fixed frame 12. The output end of the third motor 111 is fixedly connected to a third lead screw 112, which is rotatably connected inside the second fixed frame 12. A drive block 113 is threadedly connected to the outer surface of the third lead screw 112, and the drive block 113 is slidably connected inside the second fixed frame 12. The mixing pile 13 is connected to the drive block 113. By setting the third drive assembly 11, the third motor 111 drives the third lead screw 112 to rotate, causing the drive block 113 on its surface to slide inside the second fixed frame 12. This allows the drive block 113 to move the mixing pile 13, thereby changing the position of the mixing pile 13 and enabling it to fully mix the wastewater and the chemical solution.

[0030] Operating principle and advantages: Wastewater enters the first tank 1 and is filtered through the filter screen 5 before entering the lower part of the first tank 1. The second motor 101 drives the second drive gear 102 to rotate, which in turn drives the second driven gear 103 to rotate. This causes the shaft 104 to drive the second fixed frame 12 to rotate, which in turn drives the mixing pile 13 to rotate and mix the wastewater and chemicals. Simultaneously, the third motor 111 drives the third lead screw 112 to rotate, causing the drive block 113 on its surface to slide within the second fixed frame 12. This causes the slider to move the mixing pile 13, thus changing the position of the mixing pile 13. The position of the filter screen 5 improves the mixing uniformity between the drug and the wastewater, ensuring a more complete and efficient reaction. The filtered wastewater enters the second chamber 2 for treatment under the action of the water pump 3 and the water supply pipe 4. When the filter screen 5 needs to be disassembled and replaced, the first motor 71 drives the first drive gear 72 to rotate, the first drive gear 72 drives the first driven gear 73 to rotate, and the first driven gear 73 drives the first lead screw 74 to rotate, causing the L-shaped connecting rod 75 on its surface to move. The L-shaped connecting rod 75 drives the filter screen 5 to move, so that the filter screen 5 can extend out of the first chamber 1, which is convenient for maintenance personnel to maintain and provides convenience for maintenance operations.
