Description

Technical Field

[0001] The invention belongs to the technical field of filtering devices, and in particular relates to an ecological cycle restoration device for a water environment. Background Art

[0002] Ornamental ponds in parks are usually arranged outdoors for viewing purposes. Due to environmental restrictions, water resources are often supplied artificially. Ornamental ponds often cannot provide a large enough wetland environment and cannot naturally repair water quality. Long-term unattendedness will cause water quality deterioration, which will in turn affect the death of aquatic plants and fish in the water ecology, and a large amount of impurities and scum will remain in the water. It is necessary to use a special ecological cycle restoration device to repair the water in the ornamental pond. For example, an ecological cycle restoration device for a water environment proposed in patent publication number CN115259468B does not need to open the pretreatment bin for treatment, reduces manual operation, and improves the efficiency of the entire pretreatment process.

[0003] When the current water environment ecological cycle restoration device is in operation, it relies on the internal filter to filter impurities in the water. However, as the filtration time increases, the pores on the surface of the filter will gradually be blocked by impurities, causing the resistance of water flowing through the filter to increase and the water flow to decrease, thereby reducing the filtration efficiency. The traditional cleaning method is to use high-pressure water to continuously backwash the filter, which makes the overall energy consumption of the restoration device large. In addition, some larger particles or hard substances in the water may cause physical damage to the filter. Long-term water impact and impurity accumulation may also cause the filter to deform and the mesh size to become larger, affecting its normal filtration function. Once the filter is damaged or deformed, it cannot effectively filter impurities in the water. Moreover, when the filter is physically damaged, the operator cannot know the situation and replace the filter in the first time. The impurities will directly pass through the filter, causing adverse effects on the filtration performance of the ecological cycle restoration device.

[0004] Therefore, an ecological cycle restoration device for water environment is proposed to solve the above problems. Summary of the invention

The second switch 20 is electrically connected to the solenoid valve 31 through the PLC controller 5. A trigger switch 32 is fixedly connected to the upper inner wall of the analysis box 231, and the trigger switch 32 is located at the moving path of the piston seat 25. An indicator light 33 is fixedly connected to the side wall of the cross plate 16, and a buzzer 51 is fixedly connected to the rear side wall of the filter box 2.

[0037] The cleaning assembly 35 is arranged in the filter box 2 and is located inside the moving assembly 10, and is used for cleaning the filter screen 7; the cleaning assembly 35 includes a square tube 351 and a plurality of conical nozzles 352, the square tube 351 is located inside the moving assembly 10, the inner wall of the filter box 2 is fixedly connected with a high-pressure water pump 36, the liquid outlet end of the high-pressure water pump 36 is fixedly connected with a metal tube 37, the upper end of the metal tube 37 passes through the side wall of the filter box 2, and is connected with the upper side wall of the square tube 351, the side wall of the induction cylinder 151 away from the filter screen 7 is fixedly connected with a positioning electric push rod 38, and the first switch 19 is connected to the positioning electric push rod through the PLC controller 5 38 is electrically connected, the moving end of the positioning electric push rod 38 is fixedly connected with an extrusion plate 39, the side wall of the square tube 351 is fixedly connected with an extrusion switch 40, the pressing part of the extrusion switch 40 is connected with an arc seat 41, and the extrusion switch 40 is electrically connected to the high-pressure water pump 36 through the PLC controller 5. Through this component, when it is detected that the pores of the filter screen 7 are gradually blocked by impurities, the impurities in the pores of the filter screen 7 can be filtered while the impurities in the water are filtered. At the same time, the filtered liquid can be used to perform high-pressure flushing on the impurities in the pores of the filter screen 7. While ensuring the filtering efficiency of the filter screen 7, it also avoids the problem of continuous flushing with high-pressure water flow, which will cause energy waste.

[0038] The delivery pump 8 is arranged on the upper side wall of the bottom plate 1, the liquid inlet end of the delivery pump 8 is connected to the filter box 2, the liquid outlet end of the delivery pump 8 is connected to the medicine adding box 3, the upper side wall of the medicine adding box 3 is provided with a medicine adding port, and a cover plate 9 is hinged at the medicine adding port.

[0039] A high-pressure air pump 45 is fixedly connected to the rear inner wall of the filter box 2, and a nozzle 46 is fixedly connected to the air outlet of the high-pressure air pump 45. A collection frame 47 located behind the moving component 10 is fixedly connected to the upper side wall of the bottom plate 1, which can clean up impurities adhering to the surface of the filter screen 7.

[0040] The left and right inner walls of the filter box 2 are rotatably connected to the same washing roller 48, and a plurality of bristles 49 are connected to the surface of the washing roller 48. The right side wall of the filter box 2 is fixedly connected to a cleaning motor 50. The extrusion switch 40 is electrically connected to the cleaning motor 50 through the PLC controller 5. The output end of the cleaning motor 50 is connected to the washing roller 48, so as to wash away impurities adhering to the surface of the filter screen 7.

[0041] The operating principle of the present invention is now described as follows: an electrical signal is transmitted to the PLC controller 5 through the control console 4. After receiving the electrical signal, the PLC controller 5 will control the driving motor 12 to work, and the driving motor 12 drives the rear driving roller 13 and the transmission shaft 101 to rotate, thereby driving the conveying belt 102 and the filter screen 7 to rotate together, and then the sewage is transported to the inside of the filter box 2 through the liquid inlet pipe 6. The sewage will be transported to the top of the filter screen 7 through the liquid inlet pipe 6. After the sewage passes through the filter screen 7, the impurities in the sewage will stay on the surface of the filter screen 7. During the backward rotation of the filter screen 7, the impurities will be driven to move together. When the filter screen 7 drives the impurities to pass through the opening 14 and the filter screen 7 rotates to the bottom, the impurities on the surface of the filter screen 7 will fall into the collection frame 47 under the action of gravity. In addition, while the equipment is working, the PLC controller 5 will also control the high-pressure air pump 45 to work at the same time. The high-pressure air pump 45 sprays high-speed airflow through the nozzle 46, which can blow off the impurities adhering to the surface of the filter screen 7.

[0042] When there are too many impurities blocking the pores of the filter screen 7, the weight of the filter screen 7 will increase. When the filter screen 7 rotates to the bottom of the conveyor belt 102, the filter screen 7 will drive the sensing frames 152 on both sides to move downward under the action of gravity to overcome the elastic force of the spring, so that the sensing frames 152 continue to squeeze the first switch 19, and the first switch 19 will control the two corresponding positioning electric push rods 38 above the filter screen 7 through the PLC controller 5 to drive the squeezing plate 39 to move upward to the set position (when the first switch 19 and the sensing frame 152 are separated, the PLC controller 5 will immediately control the positioning electric push rod 38 to retract to the initial position, thereby avoiding the impact of the filtered water flow, which will cause misjudgment). When the conveyor belt 102 drives the squeezing plates 39 to rotate, the two squeezing plates 39 will squeeze the arc seat 41 in turn, so that the arc seat 41 moves upward and presses the squeezing switch 40. After the squeezing switch 40 is triggered, the PLC controller 5 controls the high-pressure water pump 36 to work regularly for three seconds. The high-pressure water pump 36 conveys the filtered water to the square tube 351 through the metal pipe 37, and sprays it through the conical nozzle 352 to backwash the filter 7 to clean up some impurities. The PLC controller 5 will also control the cleaning motor 50 to work regularly, and the cleaning motor 50 will drive the washing roller 48 to rotate. The washing roller 48 cleans up the impurities that are difficult to clean in the pores of the filter 7 through the bristles 49.

[0043] When sewage is transported from the liquid inlet pipe 6 to the surface of the filter screen 7, the sewage will have a certain impact on the filter screen 7, and the smaller the mesh of the filter screen 7, the greater the impact on the filter screen 7. After the filter screen 7 is impacted by the water flow, it will drive the induction frame 152 to move downward through the cross plate 16, and the induction frame 152 will drive the conductive frame 21 to move downward. When the water pressure in the liquid inlet pipe 6 reaches the set pressure range, the piston block 422 will move upward under the action of the water pressure to squeeze the control switch 44, and the control switch 44 will send an electrical signal to the PLC controller 5. After receiving the electrical signal, the PLC controller 5 will control the conductive frame 21 to be electrically connected to the external power supply. When the filtering performance of the filter 7 is intact, the filter 7 will be impacted by a large water flow, and the filter 7 will drive the conductive frame 21 to move downward a long distance. The conductive frame 21 will contact the conductive plate 22 and squeeze the second switch 20. The conductive plate 22 is electrically connected to the micro electric push rod 232 through the PLC controller 5. When the conductive frame 21 contacts the conductive plate 22, an electrical signal will be transmitted to the PLC controller 5. After receiving the electrical signal, the LC controller 5 will control the micro electric push rod 232 to reciprocate once, and the micro electric push rod 232 will drive the piston plate 24 to reciprocate once. When the micro electric push rod 232 drives the piston plate 24 to move in the direction close to the sealing plate 26, the piston plate 24 will squeeze the space between the sealing plate 26, so that the air pressure in the space will increase. Under the action of the air pressure, the gas will be transported to the space between the piston seat 25 and the sealing plate 26 through the cross pipe 27 and the one-way valve 29, so that the air pressure between the piston seat 25 and the sealing plate 26 will increase, and the piston Under the action of air pressure, the seat 25 will overcome the spring force and move a distance towards the trigger switch 32 (at this time, the trigger switch 32 will not squeeze the trigger switch 32). Referring to the above principle, when the micro electric push rod 232 drives the piston plate 24 to retract, the external gas will enter the analysis box 231 through the vertical pipe 28 and the one-way valve 29. When the conductive frame 21 continues to move downward and squeezes the second switch 20, the second switch 20 will control the solenoid valve 31 to open, so that the gas between the piston seat 25 and the sealing plate 26 is discharged through the vent pipe 30.

[0044] On the contrary, when the mesh of the filter 7 becomes larger or damaged due to wear, the impact force of the water flow on the filter 7 is relatively small, the downward moving distance of the conductive frame 21 will also become smaller, and the second switch 20 will not be squeezed, and the gas between the piston plate 24 and the sealing plate 26 will not be discharged. When the filter 7 rotates one circle and passes under the water flow again, referring to the above principle, the piston plate 24 will continue to move in the direction of the trigger switch 32 and squeeze the trigger switch 32. The trigger switch 32 will control the solenoid valve 31 to open and discharge the gas inside the analysis box 231. At the same time, the PLC controller 5 controls the buzzer 51 and the corresponding indicator light 33 to continue working, reminding the operator that the filter 7 is seriously worn and needs to be replaced. The operator can quickly find the worn filter 7 by observing the position of the indicator light 33. The operator can replace the worn filter 7 after the device stops working, and clean up some impurities that pass through the worn filter 7 and stay on the back of other filter screens 7.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
