Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a wastewater filtration device for construction sites. Background Technology

[0002] Construction sites are important infrastructure projects that generate large amounts of wastewater during construction. This wastewater contains a significant amount of sand, concrete residue, and other impurities. Discharging this wastewater into the natural environment would not only waste water resources but also cause serious damage to the ecological environment. Therefore, it is necessary to filter and recycle construction site wastewater.

[0003] The common method of treating construction wastewater is to filter the wastewater after sedimentation. This process takes a long time, has low efficiency, and the sand and gravel filter screens are prone to clogging after long-term use, which affects the filtration efficiency of the wastewater.

The filtration section includes two fixed plates 7 and several partition plates 8 connected between the two fixed plates 7. A filter plate 9 is rotatably connected to the upper side of the partition plate 8. A filtration chamber 10 is formed between two adjacent partition plates 8. A rinsing component is provided inside the filtration chamber 10.

[0034] The partition plate 8 is arranged along the diagonal direction of the fixed plate 7, the two fixed plates 7 are arranged coaxially, and the two sides of the filter plate 9 in the width direction are in contact with the two partition plates 8.

[0035] like Figure 1 and Figure 2 As shown, the two support bases are the first support base 1 and the second support base 2, respectively. The upper part of the first support base 1 is fixed with a drive motor 3, and the upper part of the second support base 2 is connected with a drain pan 4. The outer side of the drain pan 4 is connected with a drain pipe 5.

[0036] like Figure 7 As shown, a drive shaft 6 is connected between the two fixed plates 7. One end of the drive shaft 6 passes through the fixed plate 7 and is fixedly connected to the output shaft of the drive motor 3. The other end of the drive shaft 6 passes through the fixed plate 7 and is rotatably connected to the drain plate 4.

[0037] The first support base 1 and the second support base 2 are arranged vertically and parallel to each other, and the drive shaft 6 and the fixed plate 7 are arranged coaxially.

[0038] like Figure 4 As shown, the fixed plate 7 is square, and the number of partition plates 8 is at least 4. The partition plates 8 are arranged in a circular array along the outer side of the drive shaft 6. The partition plates 8 and the fixed plate 7 are sealed together. The filter chamber 10 is triangular prism-shaped. The lower part of the filter chamber 10 is provided with a horizontal baffle 11. One end of the baffle 11 is fixedly connected to one of the two adjacent partition plates 8. One side of the baffle 11 in the length direction forms a water inlet with the other of the two adjacent partition plates 8. One end of the flushing assembly is connected to the lower side of the baffle 11, and the upper part of the flushing assembly is located on the lower side of the filter plate 9.

[0039] like Figure 2 As shown, the filter plate 9 includes a frame and a filter screen. The filter screen is fixed inside the frame, and the frame is rotatably connected to the side of the partition plate 8 away from the direction of rotation.

[0040] The pore size of the filter screen is selected according to the actual filtration requirements.

[0041] like Figure 5 and Figure 8 As shown, the rinsing assembly includes a connecting water pipe 12 and a spray head 13. One end of the connecting water pipe 12 passes through the baffle 11 and is located at the lower part of the filter chamber 10. The upper end of the connecting water pipe 12 is located at the lower side of the filter plate 9. A fixed seat is connected to the upper end of the connecting water pipe 12. The spray head 13 is rotatably connected to the fixed seat. A cleaning motor 15 is connected to the connecting shaft between the spray head 13 and the fixed seat. The spray end of the spray head 13 is located facing the lower side of the filter plate 9. A solenoid valve 14 is connected to the connecting water pipe 12.

[0042] The length of the spray head 13 is equal to the length of the filter plate 9, or the width of the spray surface of the spray head 13 is equal to the length of the filter plate 9.

[0043] like Figure 7 As shown, the outer side of the fixed plate 7 adjacent to the drainage tray 4 is provided with a limiting slider and several drainage outlets. The inner side of the drainage tray 4 is provided with a limiting slide rail. The limiting slider is slidably connected to the limiting slide rail. The drainage outlets are arranged opposite to the drainage pipe 5.

[0044] like Figure 1 As shown, a weighing sensor 16 is provided at the bottom of the two support bases.

[0045] This solution also includes a controller, the location of which is set by the operator according to the actual situation. The controller is used to control all electrical components within this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication equipment, lights, speakers, and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is either AC power or a lithium battery. When a display screen is provided, a graphics card is also included. Other automation control and electrical components not mentioned are well-known to those skilled in the art and will not be described further here.

[0046] The following describes the method of using the construction site wastewater filtration device of the present invention:

[0047] In practical use, wastewater containing sand and gravel is directly flushed into the filter device through the inlet pipe. The axis of the inlet pipe and the axis of the drive shaft 6 are located in the same vertical plane.

[0048] The uppermost filter plate 9 is horizontally positioned. This filter plate 9 is the first filter plate 17, and its drain outlet is connected to the drain pipe 5. When the liquid level is higher than the drain outlet and the drain pipe 5, the filtered water is discharged through the drain pipe 5. Figure 8 The first state is shown.

[0049] By setting a certain weight threshold through the controller, the weight of the entire filter device is detected by the weighing sensor 16. When the weight of the entire filter device exceeds the weight threshold, it indicates that the weight of the sand and gravel on the upper side of the first filter plate 17 has reached the upper limit.

[0050] The controller controls the drive motor 3 to rotate the filter section by a rotation angle of 90°+n, where n ranges from 10° to 30°, causing the first filter plate 17 to rotate to an inclined state. Figure 9 As shown in the second state, the first filter plate 17 can rotate outward under the action of gravity. Figure 10 The third state is shown.

[0051] The controller controls the drive motor 3 to rotate the filter section in the opposite direction (n), so that the first filter plate 17 returns to a horizontal state. Figure 11 As shown.

[0052] The water inlet pipe continues to flush water onto the horizontal filter plate 9 for filtration.

[0053] Since the first filter plate 17 is in a horizontal state, the water that cannot be discharged from the filter chamber 10 through the drain pipe 5 is discharged along the partition plate 8 and the first filter plate 17 to rinse the first filter plate 17.

[0054] The controller controls the operation of the solenoid valve 14 and the spray head 13, so that the water inside the baffle 11 is sprayed out through the connecting water pipe 12. During the spraying process, the controller controls the cleaning motor 15 to drive the spray head 13 to rotate, so that the spray head 13 thoroughly rinses the first filter plate 17.

[0055] As the filtration section continues to rotate, the first filter plate 17 rotates from a horizontal state to a vertical state, and finally returns to the upper part of the fixed plate 7.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
