[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a wastewater filtration device for construction sites, comprising a filter chamber, a feed funnel fixedly mounted on the top of the filter chamber, a water inlet pipe fixedly mounted on the top periphery of the filter chamber, a water outlet pipe fixedly mounted on the bottom periphery of the filter chamber, and a switch valve fixedly mounted on the periphery of the water outlet pipe. A partition is fixedly mounted in the middle of the inner cavity of the filter chamber, and water pipes are fixedly mounted on both sides of the bottom of the partition. An electrically controlled valve is fixedly mounted on the periphery of the water pipes. A stirring assembly for wastewater purification is mounted on the top of the partition, and a filter assembly for wastewater filtration is mounted on the bottom of the partition. A drive device for simultaneous operation of the stirring assembly and the filter assembly is mounted on one side of the outer periphery of the filter chamber.

[0007] Furthermore, the stirring assembly includes a stirring element, and a connecting rod is fixedly provided at the top axis of the stirring element. The connecting rod is located at the top axis of the inner wall of the filter chamber and is rotatably connected to the filter chamber through a bearing. A rotating rod is rotatably connected to the top inner cavity of the filter chamber through a bearing. One end of the rotating rod extends to the outer periphery of the filter chamber. A bevel gear set that meshes with each other is sleeved on one side of the outer periphery of the rotating rod and the top of the connecting rod.

[0008] Furthermore, the filter assembly includes a conical filter plate, an activated carbon filter plate is fixedly mounted at the bottom of the conical filter plate, vertical rods are fixedly connected to both sides of the bottom of the partition, the vertical rods penetrate the conical filter plate and the activated carbon filter plate, a stop block is fixedly mounted at the bottom of the vertical rods, and a spring is sleeved on the outer periphery of the vertical rods, with the springs located at the top of the conical filter plate.

[0009] Furthermore, the filter assembly includes a conical filter plate, an activated carbon filter plate is fixedly mounted at the bottom of the conical filter plate, vertical rods are fixedly connected to both sides of the bottom of the partition, the vertical rods penetrate the conical filter plate and the activated carbon filter plate, a stop block is fixedly mounted at the bottom of the vertical rods, and a spring is sleeved on the outer periphery of the vertical rods, with the springs located at the top of the conical filter plate.

[0012] During wastewater filtration, the appropriate treatment agent is poured into the inner cavity of the filter chamber and the top of the baffle through the feed funnel. Wastewater is discharged into the filter chamber through the inlet pipe. Then, a motor drives one of the pulleys to rotate, and the meshing between the transmission belt and the two pulleys causes both pulleys to rotate simultaneously. This, in turn, drives the movable rod and the rotating rod to rotate simultaneously. When the rotating rod rotates, it drives the bevel gear set, which in turn drives the rotation of the agitator, thus fully mixing the water source and the appropriate treatment agent at the top of the baffle. The movable rod rotates, and the mixture is set on a circular... The design at one edge of the plate allows the circular plate to rotate around the movable rod. When the circular plate rotates upwards away from the movable rod, its outer circumference impacts the activated carbon filter plate, shaking off impurities from the top of the conical filter plate and causing the activated carbon filter plate to rise. When the circular plate rotates downwards away from the movable rod, the spring force causes the activated carbon filter plate to descend, resulting in up-and-down vibration of the activated carbon filter plate. Simultaneously, the triangular cross-sectional shape of the conical filter plate ensures that impurities on the conical filter plate are shaken off to the edge of the conical filter plate, preventing clogging.

[0024] Please see Figure 1-5 As shown, this utility model is a wastewater filtration device for construction sites, including a filter chamber 1, a feed funnel 2 fixedly installed on the top of the filter chamber 1, a water inlet pipe 3 fixedly installed on the top of the outer periphery of the filter chamber 1, a water outlet pipe 4 fixedly installed on the bottom of the outer periphery of the filter chamber 1, and a switch valve 5 fixedly installed on the outer periphery of the water outlet pipe 4. A partition 6 is fixedly installed in the middle of the inner cavity of the filter chamber 1. Water pipes 10 are fixedly installed on both sides of the bottom of the partition 6. An electric control valve 11 is fixedly installed on the outer periphery of the water pipes 10. A stirring assembly 7 for wastewater purification is installed on the top of the partition 6. A filter assembly 8 for wastewater filtration is installed on the bottom of the partition 6. A drive device 9 for simultaneous operation of the stirring assembly 7 and the filter assembly 8 is installed on one side of the outer periphery of the filter chamber 1.

[0025] When filtering wastewater, the corresponding treatment agent is poured into the inner cavity of the filter chamber 1 and the top of the partition 6 through the feed funnel 2, and the wastewater is discharged into the filter chamber 1 through the water inlet pipe 3. Then, the stirring component 7 and the filtering component 8 are operated simultaneously through the setting of the drive component. The wastewater is purified by the setting of the stirring component 7. The purified water is discharged into the bottom of the partition 6 through the water pipe 10. At the same time, the impurities in the wastewater are filtered by the setting of the filtering component 8. Finally, the filtered water is discharged from the drain pipe.

[0026] In one embodiment, the stirring assembly 7 includes a stirring element 71. A connecting rod 72 is fixedly provided at the top axis of the stirring element 71. The connecting rod 72 is located at the top axis of the inner wall of the filter chamber 1 and is rotatably connected to the filter chamber 1 via a bearing. A rotating rod 73 is rotatably connected to the top inner cavity of the filter chamber 1 via a bearing. One end of the rotating rod 73 extends to the outer periphery of the filter chamber 1. A bevel gear set 74 that meshes with the top of the connecting rod 72 is sleeved on one side of the outer periphery of the rotating rod 73. The bevel gear set 74 drives the stirring element 71 to rotate, thereby fully mixing the water source and the corresponding treatment agent at the top of the partition 6.

[0027] In one embodiment, the filter assembly 8 includes a conical filter plate 81, with an activated carbon filter plate 82 fixedly mounted at the bottom of the conical filter plate 81. Vertical rods 83 are fixedly connected to both sides of the bottom of the partition 6, penetrating the conical filter plate 81 and the activated carbon filter plate 82. A stop block is fixedly mounted at the bottom of the vertical rod 83, and a spring 84 is sleeved around the outer periphery of the vertical rod 83, located at the top of the conical filter plate 81. The conical filter plate 81, when vibrating, causes the conical filter plate 81 to... Impurities at the top of the filter plate 81 are shaken off to its outer periphery, thus preventing impurities in the sewage from clogging the conical filter plate 81. In addition, in specific applications, the conical filter plate 81 performs primary filtration of the water source, while the activated carbon filter plate 82 performs secondary filtration of the water source. At the same time, the conical filter plate 81 and the activated carbon filter plate 82 are movable by sliding between the conical filter plate 81 and the vertical rod 83, and the conical filter plate 81 and the activated carbon filter plate 82 are driven to move downward by the setting of the spring 84.

[0028] In one embodiment, for the aforementioned conical filter plate 81 and activated carbon filter plate 82, a movable rod 85 is rotatably connected to the inner cavity of the filter chamber 1 via a sealed bearing. One end of the movable rod 85 extends to the outer periphery of the filter chamber 1. The movable rod 85 is located at the bottom of the activated carbon filter plate 82, and circular plates 86 are fixedly provided on both sides of the outer periphery of the movable rod 85. The movable rod 85 is located at one edge of the circular plate 86. By setting the movable rod 85 at one edge of the circular plate 86, when the circular plate 86 rotates around the movable rod 85 as its axis, when the circular plate 86 moves away from the movable rod 85... When one side rotates upward, the outer periphery of the circular plate 86 will impact the activated carbon filter plate 82, thereby shaking off the impurities at the top of the conical filter plate 81 and causing the activated carbon filter plate 82 to rise. When the circular plate 86 rotates downward away from the movable rod 85, the elastic force provided by the spring 84 will cause the activated carbon filter plate 82 to fall, thereby causing the activated carbon filter plate 82 to vibrate up and down. At the same time, the triangular cross-sectional shape of the conical filter plate 81 will cause the impurities on the conical filter plate 81 to fall to the edge of the conical filter plate 81, avoiding the clogging of the conical filter plate 81 by impurities.

[0029] In one embodiment, the drive device 9 includes two pulleys 91, which are respectively located at the top and bottom of the outer periphery of the filter chamber 1. One end of the movable rod 85 and the rotating rod 73 are fixedly connected to the shaft center of the two pulleys 91. A transmission belt 92 that meshes with the pulleys 91 is sleeved on the outer periphery of the two pulleys 91. A fixed platform is fixed on one side of the outer periphery of the filter chamber 1, and a motor 93 for driving one of the pulleys 91 to rotate is fixed on one side of the fixed platform. The motor 93 drives one of the pulleys 91 to rotate, and the meshing between the transmission belt 92 and the two pulleys 91 drives the two pulleys 91 to rotate simultaneously, thereby driving the movable rod 85 and the rotating rod 73 to rotate simultaneously, and thus driving the stirring assembly 7 and the filtering assembly 8 to operate simultaneously.

[0030] In summary, using the above-mentioned technical solution of this utility model, when filtering sewage, the corresponding treatment agent is poured into the inner cavity of the filter chamber 1 and the top of the partition 6 through the feed funnel 2, and the sewage is discharged into the filter chamber 1 from the inlet pipe 3. Then, the motor 93 drives one of the pulleys 91 to rotate, and the meshing between the transmission belt 92 and the two pulleys 91 drives the two pulleys 91 to rotate simultaneously, thereby driving the movable rod 85 and the rotating rod 73 to rotate simultaneously. When the rotating rod 73 rotates, it drives the bevel gear set 74 to run, thereby driving the agitator 71 to rotate, thus fully mixing the water source and the corresponding treatment agent at the top of the partition 6. The movable rod 85 rotates, and through the movable rod 8... The 5-positioned feature, located at one edge of the circular plate 86, allows the circular plate 86 to rotate around the movable rod 85. When the circular plate 86 rotates upward away from the movable rod 85, its outer periphery impacts the activated carbon filter plate 82, shaking off impurities from the top of the conical filter plate 81 and causing the activated carbon filter plate 82 to rise. When the circular plate 86 rotates downward away from the movable rod 85, the spring force provided by the spring 84 causes the activated carbon filter plate 82 to descend, resulting in up-and-down vibration of the activated carbon filter plate 82. Simultaneously, the triangular cross-sectional shape of the conical filter plate 81 ensures that impurities on the conical filter plate 81 are shaken off to the edge of the conical filter plate 81, preventing impurities from clogging the conical filter plate 81.

[0031] Through the above technical solution, by setting the conical filter plate 81 with a triangular cross-section, by rotating the circular plate 86 in the stirring assembly 7 around the movable rod 85 as the axis, and by setting the movable rod 85 at one edge of the circular plate 86, when the circular plate 86 rotates upward away from the movable rod 85, the outer periphery of the circular plate 86 will hit the activated carbon filter plate 82, thereby shaking off the impurities at the top of the conical filter plate 81 and causing the activated carbon filter plate 82 to rise. When the circular plate 86 rotates downward away from the movable rod 85, the elastic force provided by the spring 84 will cause the activated carbon filter plate 82 to fall, thereby causing the activated carbon filter plate 82 to vibrate up and down, so that the impurities on the conical filter plate 81 are shaken off to the edge of the conical filter plate 81, avoiding the impurities from clogging the conical filter plate 81.
