[0040] It should be noted that when the sludge in the sludge is precipitated, the upper water is treated and can be reused, at this time, the upper water needs to be pumped out, and the general way is to directly pump out the upper water, which can easily cause the bottom precipitated slurry to be mixed with water again, thereby causing the blockage of the water pumping pipeline and the filter, which is time-consuming and laborious and has low water pumping efficiency. The device separates the sedimentation tank 11 into a stirring sedimentation tank and a drainage tank by the partition plate 15, the lower end of the partition plate 15 is provided with a filter port, the water in the stirring sedimentation tank after the sludge is precipitated can be discharged into the drainage tank, the middle part of the stirring sedimentation tank and the drainage tank is provided with a filter mechanism, and the filter screen 37 in the filter mechanism can be replaced in time, thereby not affecting the speed of discharging water from the stirring sedimentation tank to the drainage tank. At this time, when the water in the drainage tank is pumped out, the probability of damage to the water pumping equipment will be greatly reduced, thereby improving the water pumping speed, specifically:
[0041] A flow rate sensor is arranged in the drainage port 39, which is used to detect the flow rate in the drainage port and send it to the main controller 13, which controls whether the drainage switch 310 closes the drainage port 39. The specific analysis process is as follows:
[0042] The flow rate sensor detects the water flow rate to obtain a flow rate value V1, and sets the drainage switch 310 to close the drainage port 39 at a flow rate value V2. When V1≤V2, the main controller 13 controls the drainage switch 310 to close the drainage port 39.
[0043] When the drainage port 39 is closed, the main controller 13 drives the filter plate 31 to slide in the filter plate 31 and the sedimentation tank 11 to replace the filter screen 37;
[0044] Then the filter screen collection module 312 collects the filter screen picture of the filter screen 37;
[0045] The filter screen collection module 312 is used to collect the filter screen picture of the filter screen and send it to the main controller 13, and the main controller 13 analyzes the filter screen picture. The specific analysis process is as follows:
[0046] The filter screen picture is enlarged by several times and is divided into several picture grids, the color of the picture grid is identified, and the color of the picture grid is compared with the corresponding picture grid color of the filter screen preset picture. When the colors are inconsistent, the picture grid is marked as a color difference grid; the number of color difference grids is counted and converted into a corresponding area to obtain a filter screen blockage area S1.
[0047] Identify the RGB color of color difference, set several block colors, each block color corresponds to a block preset value; compare the RGB color of color difference with several block colors, if the RGB color is consistent with the block color, mark the block preset value as the color difference block preset value; sum all the block preset values matched by the color difference to obtain the total block value D2;
[0048] Extract the numerical value of the filter screen blockage area and the total block value, and substitute it into the formula DS=S1×e1+D2×e2 to obtain the blockage degree value DS; set two intervals, a flushing interval and a replacement interval; compare the two intervals with the blockage degree value DS, when the blockage degree value DS belongs to the flushing interval, generate a flushing instruction; when the blockage degree value DS belongs to the replacement interval, generate a replacement instruction;
[0049] When the flushing instruction is generated, the main controller 13 controls the water pump 311 to work, and at the same time, the filter screen 37 is flushed under the action of the high-pressure nozzle 313. Since the stress direction of the dirt blocked by the filter screen 37 is opposite to the flushing direction, flushing the filter screen 37 through the high-pressure nozzle 313 can remove the dirt blocked by the filter screen 37;
[0050] When the replacement instruction is generated, it is fed back to the corresponding personnel, who clamps the push rod 36 through a tool and pushes the push rod 36. At this time, the sliding plate 35 drives the arc-shaped limiting plate 33 to release the limiting clamping of the middle part of the filter screen 37, and the filter screen 37 is replaced.
[0051] The water pumping mechanism includes a second servo motor 41 arranged on the side of the sedimentation tank 11. The output end of the second servo motor 41 is connected with a rotating shaft 42 through a shaft coupling. The end of the rotating shaft 42 away from the second servo motor 41 is provided with a driving bevel gear 43. The circumferential surface of the driving bevel gear 43 is connected with a driven bevel gear 44. The lower surface of the driven bevel gear 44 is provided with a threaded rod 45. The circumferential surface of the threaded rod 45 is threadedly connected with a moving plate 46. The moving plate 46 is slidingly connected with a limiting slide rod 47. The limiting slide rod 47 is arranged on the opposite side of the threaded rod 45. The inner side wall of the sedimentation tank 11 is provided with a limiting plate 48. The threaded rod 45 penetrates through the limiting plate 48. The limiting slide rod 47 is also provided with a limiting plate 48 between the limiting slide rod 47 and the sedimentation tank 11. The limiting plate 48 can fix the threaded rod 45 and the limiting slide rod 47 in the sedimentation tank 11. The circumferential surfaces of the threaded rod 45 and the limiting slide rod 47 are both provided with second springs 49. The starting ends of the second springs 49 are connected with the limiting plate 48. The upper surface of the limiting plate 48 is provided with a first sensor 410. The upper surface of the moving plate 46 is provided with a connecting pipe 411. The lower surface of the moving plate 46 is provided with a water pumping pipe 412. The connecting pipe 411 and the water pumping pipe 412 are in communication. The lower surface of the moving plate 46 is provided with a second sensor 413.
[0052] It should be noted that when the water in the upper middle layer of the sedimentation and stirring tank of the sedimentation tank 11 is discharged into the drainage tank, the external water pump is connected to the connecting pipe 411 of the device through the water pipe, and then the water surface in the drainage tank is sensed by the second sensor 413 to obtain the water surface height, which is transmitted to the main controller 13, and then the main controller 13 controls the second servo motor 41 to work, so that the moving plate 46 descends, so that the water surface is always just submerged in the water suction pipe 412, ensuring that the water suction pipe 412 can always extract water. The second servo motor 41 works to drive the rotating shaft 42 to rotate in the forward direction, the rotating shaft 42 rotates to drive the driving bevel gear 43 to rotate, the driving bevel gear 43 rotates to drive the driven bevel gear 44 to rotate, and the driven bevel gear 44 rotates to drive the threaded rod 45 to rotate. The threaded rod 45 rotates while being limited by the limiting rotation of the limiting slide rod 47 to make the moving plate 46 descend. The moving plate 46 descends to drive the water suction pipe 412 to descend until the water suction pipe 412 is just submerged by the water surface. After the water in the drainage tank is pumped away, the second servo motor 41 will work again as the water surface in the drainage tank drops, so that the water surface is always just submerged in the water suction pipe 412, ensuring that the water suction pipe 412 can always extract water, improving the water pumping efficiency. When the water suction pipe 412 descends to the position where it just contacts the inner bottom wall of the drainage tank, the moving plate 46 will compress the second spring 49. At this time, the first sensor 410 receives the pressure sensing signal and transmits it to the main controller 13. At this time, the main controller 13 receives the pressure sensing signal and closes the second sensor 413, and at the same time makes the second servo motor 41 reverse to make the moving plate 46 rise until the moving plate 46 rises to the position where it is flush with the upper surface of the sedimentation tank 11. The second servo motor 41 stops working.
[0053] Step one, the sedimentation tank 11 is divided into a stirring sedimentation tank and a drainage tank. The stirring mechanism is in the stirring sedimentation tank, and the water suction mechanism is in the drainage tank. The wastewater is discharged into the stirring sedimentation tank through the liquid inlet 14. At this time, the first servo motor 22 works to drive the rotating rod 24 to rotate, and the rotating rod 24 rotates to drive the helical blades 25 on its circumference to rotate, thereby stirring the mud-water mixture. Its role is to mix the bottom mud and water through mechanical stirring, and to promote the downward sedimentation of suspended particles, thereby accelerating the sedimentation speed of solid substances and improving the sedimentation efficiency of mud and water. The inclined plate sedimentation tank 26 can form a slope at the bottom of the sedimentation tank 11, so that the sludge and suspended particles can be deposited at the bottom under the action of gravity. At the same time, due to the narrow bottom of the inclined plate sedimentation tank 26, the sediment can easily accumulate at the bottom.
[0054] Step two, when the sludge in the sludge after sedimentation partition 15 lower end is provided with filter port, the stirring sedimentation tank sludge after sedimentation water can be discharged into the drainage tank, wherein the stirring sedimentation tank and drainage tank in the middle is provided with filter mechanism, and the filter screen 37 in the filter mechanism can be replaced in time, and then will not affect the stirring sedimentation tank to drainage tank drainage speed, at this time in the water in the drainage tank is extracted, will greatly reduce the probability of damage of pumping equipment blockage, and then improve the pumping speed, specifically:
[0055] The flow rate sensor is arranged in the drainage port 39, and the flow rate sensor is used for detecting the flow rate in the drainage port and sending it to the host computer 13. The host computer 13 controls whether the drainage switch 310 closes the drainage port 39. The specific analysis process is:
[0056] The flow rate sensor detects the water flow rate to obtain the flow rate value V1. The drainage switch 310 is closed when the flow rate value V2 is set. When V1≥V2, the host computer 13 controls the drainage switch 310 to close the drainage port 39.
[0057] When the drainage port 39 is closed, the host computer 13 drives the filter plate 31 to slide in the filter plate 31 and the sedimentation tank 11 to replace the filter screen 37.
[0058] Then the filter screen collection module 312 collects the filter screen picture of the filter screen 37;
[0059] The filter screen collection module 312 is used for collecting the filter screen picture of the filter screen and sending it to the host computer 13. The host computer 13 analyzes the filter screen picture. The specific analysis process is:
[0060] The filter screen picture is enlarged by several times and is divided into several picture grids. The color of the picture grid is identified and compared with the picture grid color corresponding to the filter screen preset picture. When the colors are inconsistent, the picture grid is marked as color different grid. The number of color different grids is counted and converted into corresponding area to obtain the filter screen blocking area S1.
[0061] The RGB color of the color different grid is identified. A plurality of blocking colors are set, and each blocking color corresponds to a blocking preset value. The RGB color of the color different grid is compared with the plurality of blocking colors. If the RGB color is consistent with the blocking color, the blocking preset value is marked as the blocking preset value of the color different grid. The blocking preset values matched by all color different grids are summed to obtain the total blocking value D2.
[0062] The value of the clogging area and the total clogging value of the extraction filter screen is substituted into the formula DS=S1×e1+D2×e2 to obtain the clogging degree value DS; two intervals are set, a flushing interval and a replacement interval; the two intervals are compared with the clogging degree value DS, when the clogging degree value DS belongs to the flushing interval, a flushing instruction is generated; when the clogging degree value DS belongs to the replacement interval, a replacement instruction is generated;
[0063] When the flushing instruction is generated, the host controller 13 controls the water pump 311 to work, and at the same time, the filter screen 37 is flushed under the action of the high-pressure nozzle 313. Since the force direction of the stains clogging the filter screen 37 is opposite to the flushing direction, the filter screen 37 is flushed by the high-pressure nozzle 313 to remove the clogging of the filter screen 37;
[0064] When the replacement instruction is generated, it is fed back to the corresponding personnel, the personnel clamps the push rod 36 by a tool, and pushes the push rod 36. At this time, the slide plate 35 drives the arc-shaped limiting plate 33 to release the limiting clamping of the middle part of the filter screen 37, and the filter screen 37 is replaced.
