Description

Technical Field

[0001] This invention relates to an adaptive backwashing treatment device for textile wastewater, belonging to the field of wastewater treatment technology. Specifically, it relates to a treatment device that uses multiple sets of filter components with different precision filters to filter wastewater multiple times, and uses a backwashing component to monitor filter blockage with a pressure sensor to accurately clean the filter, thereby improving the filtration speed and effect. Background Technology

[0002] The textile industry generates large amounts of wastewater containing various impurities and chemical pollutants, which must be treated before being discharged into the environment. Currently, traditional textile wastewater treatment equipment exhibits a series of problems in practical applications. Regarding filtration, most existing devices are equipped with only a single or simple filter assembly, failing to effectively treat the characteristics of different stages of wastewater purification. The use of a single-precision filter screen makes it difficult to meet the needs of progressive filtration from initial filtration to the removal of large particles, small particles, and fine impurities, resulting in poor filtration performance. Even after treatment, a significant amount of pollutants remain in the wastewater, failing to meet ideal filtration standards and placing considerable pressure on the environment. Furthermore, existing devices lack effective means for real-time monitoring of filter clogging, typically relying on periodic manual inspections. This is not only labor-intensive and time-consuming but also makes it difficult to detect filter clogging promptly. When filter clogging is severe, the backwashing process cannot be automatically activated in time, causing a significant decrease in filtration speed, low wastewater treatment efficiency, and severely impacting production progress.

[0003] Publication number CN220443321U discloses a wastewater filtration device, which includes a housing, a filter assembly, and multiple nozzles. The housing has a cavity, the filter assembly is disposed within the cavity, and the nozzles are disposed within the cavity. The multiple nozzles are arranged at intervals along the circumference of the housing, facing the filter assembly, and are located downstream of the filter assembly in the direction of water flow. However, when the above-mentioned wastewater filtration device operates for a long time, impurities tend to accumulate on the surface of the filter screen, resulting in a slow filtration speed and affecting the filtration effect. Summary of the Invention

The middle part of the water pipe (10) passes through the second water pump (9). The filter assembly consists of a fixed plate (21) and a filter screen (12). The fixing plate (21) is fixedly connected to the inner side of the filter tank (1). The filter screen (12) is fixedly connected to the fixing plate (21) near its bottom side. The bottom of the filter screen (12) is an open structure. Each fixing plate (21) corresponds to multiple filter screens (12).

The backflush assembly consists of a pressure gauge (2), a backflush motor housing (19), a first connecting pipe (14), a second connecting pipe (13), a collection port (20), a first water pump (4), and a drain port (3).

The recoil motor housing (19) houses the recoil motor, and the recoil motor shaft passes through the recoil motor housing (19) with a sealed bearing between it and the housing (19). One end of the first connecting pipe (14) is fixedly connected to the motor shaft of the recoil motor inside the recoil motor housing (19), and the other end of the first connecting pipe (14) extends vertically upward and is rotatably connected to the fixing plate (21), and a connecting ring is placed between the first connecting pipe (14) and the fixing plate (21). The top end of the first connecting pipe (14) is an open structure. One end of the second connecting pipe (13) is fixedly connected to the first connecting pipe (14), and the second connecting pipe (13) communicates with the first connecting pipe (14). The second connecting pipe (13) has an L-shaped structure. Preferably, the inner walls of both the first connecting pipe (14) and the second connecting pipe (13) are coated with a smooth polytetrafluoroethylene coating. The other end of the second connecting pipe (13) is provided with a collection port (20), the diameter of which gradually increases from the end connected to the second connecting pipe (13) to the other end. The other end of the second connecting pipe (13) is attached to the bottom end of the filter screen (12). The first water pump (4) is fixedly placed on the outer side of the filter tank (1). One end of the sewage outlet (3) is fixedly connected to the fixing plate (21) and communicates with the first connecting pipe (14). The sewage outlet (3) passes through the filter tank (1) and the first water pump (4) and is located at the other end. In use, textile wastewater flows into the filter tank (1) through the inlet (6). The wastewater first flows into the space between the fixed plate (21) and the first partition plate (16) inside the lower filter cylinder, driving the air pump (8). The gas generated by the air pump (8) is transmitted through the air pipe (7). After the gas enters the hollow ring of the aeration pipe (15) through the air pipe (7), it is sprayed upward through multiple cylinders and enters the wastewater in the lower filter cylinder to disperse the wastewater and prevent impurities from accumulating. The one-way valve at the end of the air pipe (7) near the aeration pipe (15) can prevent the wastewater from flowing back. In the lower filter cylinder, wastewater enters the filter screen (12) through the bottom of the screen (12). Impurities in the wastewater are intercepted by the filter screen (12), while clean water passes through the filter screen (12) into the area between the fixed plate (21) and the second partition plate (17), thus performing the first filtration of the wastewater. At this time, the second water pump (9) is driven. The water that has undergone the first filtration is guided to the middle filter cylinder by the action of the second water pump (9) and undergoes the second filtration in the same way as the lower filter cylinder. The filtered water then enters the upper filter cylinder for the third filtration. Finally, after three filtrations, the water is filtered a third time. The filtered wastewater flows out of the device through the outlet (11). A pressure sensor is placed on the inner and outer sides of one of the filter screens (12) in each backwash assembly. During filtration, the pressure sensor detects the pressure inside and outside the filter screen (12) in real time and displays it through the pressure gauge (2). The integrated controller (5) calculates the pressure difference between the two. When the pressure difference exceeds the preset value, it indicates that the filter screen (12) is severely clogged by impurities and needs to be cleaned. At this time, the backwash motor in the backwash motor housing (19) of the corresponding filter assembly is driven. The machine shaft drives the first connecting pipe (14) to rotate. As the first connecting pipe (14) rotates, the second connecting pipe (13) fixedly connected to it also rotates synchronously, so that the collection port (20) is in contact with the bottom of the filter screen (12). The first water pump (4) is driven. Under its suction, the impurities in the filter screen (12) flow out of the device through the collection port (20), the second connecting pipe (13), the first connecting pipe (14) and the drain port (3) in sequence. By cleaning the multiple filter screens (12) in the filter assembly according to the above method, the filtration speed can be ensured. The first partition (16), the second partition (17), and the third partition (18) are arranged equidistantly along the axial direction of the filter tank (1), dividing the filter tank into three identical sealed spaces. This design provides independent and standardized spaces for multiple filtrations. The filter components in each filter cylinder can be specifically set according to the impurities in the wastewater at different stages, achieving graded filtration and significantly improving filtration efficiency and effect. The aeration pipe (15) is made of high-strength stainless steel and is designed with a hollow ring and multiple cylinders arranged equidistantly along the circumference. The high-strength stainless steel material can resist the corrosion of wastewater and withstand high gas pressure, ensuring that the aeration pipe will not deform or be damaged under long-term and frequent use, thus reducing the replacement frequency. The combination structure of the hollow ring and multiple cylinders allows the gas to be evenly dispersed in the bottom area of ​​the entire filter tank. The resulting turbulence effect covers a wide area and can effectively prevent impurities from being deposited at the bottom of the tank, avoiding local water flow obstruction due to impurity accumulation, which affects the overall treatment efficiency. Moreover, the turbulence generated by this structure helps oxygen dissolve in wastewater, providing favorable conditions for the aerobic microbial treatment process and further improving the wastewater treatment effect. Pressure sensors are installed on the inner and outer sides of the filter screen (12) in each backwash assembly. The pressure is displayed by the pressure gauge (2). The integrated controller (5) calculates the pressure difference. The design can monitor the pressure on both sides of the filter screen in real time, accurately determine the clogging of the filter screen, and automatically control the backwash operation according to the pressure difference to achieve adaptive cleaning. There is no need for frequent manual inspection and intervention, which improves the intelligence level and operating efficiency of the device. The system enables multiple filtrations of wastewater through a filtration assembly with various filter screens of different precision. The backwash assembly utilizes a pressure sensor to monitor filter screen blockage and precisely clean the screen, thereby improving filtration speed and effectiveness.
