Description

Technical Field

[0001] This invention relates to the field of fiber filter technology, and specifically to a fully automatic high-efficiency fiber filter. Background Technology

[0002] In the field of water treatment filtration, fiber filters, as a new type of deep filtration equipment, are widely used in various water treatment scenarios such as industrial wastewater treatment, domestic sewage treatment, drinking water purification, chemical wastewater reuse, power industry water supply treatment, and municipal water treatment. They are one of the core devices for achieving water purification, improving water quality compliance rates, and promoting the recycling of water resources. However, with the continuous improvement of environmental protection requirements, various water treatments have increasingly stringent requirements for filtration accuracy, treatment efficiency, and automation. Traditional filtration equipment can no longer meet the needs of large-scale, high-standard water treatment.

[0003] Existing fiber filters still have shortcomings in use. First, the filtration accuracy of existing fiber filters is mostly fixed, and cannot be flexibly adjusted according to changes in raw water quality and treatment standards. This results in poor versatility, and when the turbidity of the raw water fluctuates greatly, problems such as substandard filtration or excessive filtration resistance may occur. Second, fiber filter components are mostly fixed structures, and after long-term use, pollutants easily adhere to the surface of the fiber filaments, requiring disassembly and cleaning. This operation is cumbersome, time-consuming, and labor-intensive, and incomplete cleaning can easily lead to a decrease in filtration efficiency. Third, some filters with backwashing functions mostly use single water backwashing or air backwashing, which has poor backwashing effect and is difficult to completely remove stubborn pollutants from the surface of the fiber filaments, easily causing secondary pollution. Moreover, the backwashing process requires intervention and control, resulting in low automation. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fully automatic high-efficiency fiber filter, which can effectively solve the problems of non-adjustable filtration accuracy, poor backwashing effect, low degree of automation and cumbersome maintenance of the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a fully automatic high-efficiency fiber filter, including a filter housing, wherein a plurality of columnar filter components for filtration are equally spaced inside the filter housing, and the columnar filter components include a plurality of twistable and offset fiber filaments;

[0007] A mechanical rotation adjustment mechanism is disposed above the filter housing and is connected in drive to multiple columnar filter components. The mechanical rotation adjustment mechanism includes a starting component and multiple adjustment components. The mechanical rotation adjustment mechanism is used to apply torque to the fiber filaments to tension or relax them, so as to adjust the filter pores between the longitudinal direction of the fiber filaments.

[0009] According to the above-mentioned fully automatic high-efficiency fiber filter, the gaps between the fibers in a single columnar filter assembly are the same. By adjusting the gaps between the fibers through a mechanical rotary adjustment mechanism, the filtration accuracy of the filter can be adjusted.

[0010] According to the above-mentioned fully automatic high-efficiency fiber filter, multiple fibers in the columnar filter assembly can switch between filtration and self-cleaning states by tensioning and relaxing them with torque.

[0011] According to the above-mentioned fully automatic high-efficiency fiber filter, the columnar filter assembly further includes an annular bottom plate fixedly connected to the bottom surface of the filter housing, a rotating top plate is provided above the annular bottom plate, and a plurality of fiber filaments are fixedly connected between the annular bottom plate and the rotating top plate, and the fiber filaments are arranged at equal intervals along the circumference of the annular bottom plate and the rotating top plate.

[0012] According to the above-mentioned fully automatic high-efficiency fiber filter, the starting component includes an electric cylinder fixedly connected to the upper end face of the filter housing via a bracket. The output end of the electric cylinder is fixedly connected to a connecting frame, and both ends of the connecting frame are fixedly connected to racks. The two racks are symmetrically arranged about the electric cylinder.

[0013] According to the above-mentioned fully automatic high-efficiency fiber filter, the adjustment component includes a rotating shaft disposed inside the filter housing. The rotating shaft is rotatably connected to the upper end face of the filter housing through a bearing. The bottom end of the rotating shaft is fixedly connected to the upper surface of the rotating top plate. A gear is fixedly connected to the top end of the rotating shaft, and the gear meshes with a rack.

[0014] According to the above-mentioned fully automatic high-efficiency fiber filter, a backwashing mechanism is fixedly provided on the lower end face of the filter housing. The backwashing mechanism is used to perform air-water combined backwashing on the fiber filaments when the filtration pressure difference or filtration time reaches a set value. The backwashing mechanism includes an air backwashing component and a water backwashing component.

[0015] According to the above-mentioned fully automatic high-efficiency fiber filter, the air backwashing assembly includes multiple air supply pipes fixedly connected to the lower end face of the filter housing, and a perforated plate is fixedly connected to the inner wall of the output end of each of the multiple air supply pipes. An air inlet pipe is provided at the bottom of the filter housing, and the input ends of the multiple air supply pipes are connected to the side wall of the air inlet pipe. An air outlet pipe is fixedly connected to the upper end face of the filter housing.

[0016] According to the above-mentioned fully automatic high-efficiency fiber filter, the water backwashing assembly includes multiple inlet and outlet water pipes fixedly connected to the lower end face of the filter housing. The multiple inlet and outlet water pipes are all connected to the interior of the columnar filter assembly. The bottom ends of the multiple inlet and outlet water pipes are all fixedly connected to water supply pipes. The filter housing is provided with inlet and outlet water pipes at the bottom. The side ends of the multiple water supply pipes are all connected to the side walls of the inlet and outlet water pipes. The side wall of the filter housing is fixedly connected to a backwash outlet pipe.

[0017] According to the above-mentioned fully automatic high-efficiency fiber filter, the side wall of the filter housing is fixedly connected to the original liquid inlet pipe, the side wall of the filter housing is provided with a cleaning port, a sealing cap is fixedly fitted on the outside of the cleaning port, and the lower end face of the filter housing is fixedly connected to the drain pipe.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] 1. The present invention uses a mechanical rotary adjustment mechanism to drive the adjustment component to apply torque to the fiber filaments to achieve tensioning or relaxation, thereby adjusting the filtration pores between the fiber filaments and achieving flexible adjustment of filtration accuracy. It is suitable for different raw water qualities and treatment needs, and has strong versatility, solving the problems of fixed filtration accuracy and poor versatility of existing filters.

[0020] 2. This invention utilizes a columnar filter assembly where the fiber filaments can switch between filtration and self-cleaning states through torque tension and relaxation. Combined with a backwashing mechanism employing air and water backwashing, it efficiently removes contaminants from the fiber surface without disassembly or cleaning, simplifying operation, reducing maintenance costs, and avoiding the problem of decreased filtration efficiency caused by incomplete cleaning.

[0021] 3. The present invention uses a backwashing mechanism that employs the synergistic action of air backwashing components and water backwashing components. Air backwashing can loosen stubborn contaminants on the surface of the fiber filaments, while water backwashing can efficiently flush out the contaminants. The backwashing effect is good, avoiding secondary pollution. Furthermore, the backwashing process can be automatically started according to the filtration pressure difference or filtration time, resulting in a high degree of automation.

[0022] 4. This invention uses multiple columnar filter components that are equidistantly arranged in the filter housing to filter water from the periphery to the center of the columnar unit. Compared with conventional filtration, this increases the filtration area and thus greatly improves the filtration efficiency. At the same time, the fiber filaments are equidistantly arranged along the annular bottom plate and the rotating top plate. With the synchronous adjustment of the mechanical rotation adjustment mechanism, the filtration accuracy of each columnar filter component can be kept consistent, thus improving the filtration stability.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Example: Refer to Figures 1 to 6A fully automatic high-efficiency fiber filter includes a filter housing 1. Four columnar filter components 2 for filtration are equidistantly arranged inside the filter housing 1. Each columnar filter component 2 includes multiple twistable and offset fiber filaments 21. The fiber filaments 21 are made of polypropylene (PP) fiber material, possessing characteristics of corrosion resistance, high strength, good resilience, strong chemical stability, resistance to strong acids, strong alkalis, and strong oxidants, and resistance to biodegradation. The filter media pore size can reach several micrometers, with a large specific surface area and low filtration resistance, effectively intercepting suspended impurities, particulate matter, colloids, organic matter, and other pollutants in water. A raw liquid inlet pipe 11 is fixedly connected to the side wall of the filter housing 1. When the filter is in use, the input end of the raw liquid inlet pipe 11 is connected to a raw liquid pump, thereby achieving continuous delivery of the liquid to be filtered. A cleaning port 12 is opened on the side wall of the filter housing 1, and a sealing cap 13 is fixedly fitted over the cleaning port 12. A drain pipe 14 is fixedly connected to the lower end face of the filter housing 1.

[0034] A mechanical rotation adjustment mechanism is located above the filter housing 1 and is connected to multiple columnar filter components 2. The mechanical rotation adjustment mechanism includes a starting component 3 and multiple adjustment components 4. The mechanical rotation adjustment mechanism is used to apply torque to the fiber filaments 21 to tension or relax them, so as to adjust the filter pores between the longitudinal direction of the fiber filaments 21.

[0035] The starting component 3 provides power to multiple adjustment components 4, which are respectively engaged with multiple columnar filter components 2, thereby enabling the mechanical rotary adjustment mechanism to adjust the gap between the fiber filaments 21.

[0036] The gaps between the fiber filaments 21 in a single columnar filter assembly 2 are the same. The filtration accuracy of the filter can be adjusted by adjusting the gaps between the fiber filaments 21 through a mechanical rotary adjustment mechanism. The multiple fiber filaments 21 in the columnar filter assembly 2 can switch between filtration and self-cleaning states by tensioning and relaxing the torque. The columnar filter assembly 2 also includes an annular bottom plate 22 fixedly connected to the bottom surface of the filter housing 1. A rotating top plate 23 is provided above the annular bottom plate 22. Multiple fiber filaments 21 are fixedly connected between the annular bottom plate 22 and the rotating top plate 23. The fiber filaments 21 are arranged equidistantly along the circumference of the annular bottom plate 22 and the rotating top plate 23 to ensure filtration uniformity and avoid flow deviation and filter media disorder. In this embodiment, the suspended part of the fiber filaments 21 participates in backwashing but does not participate in filtration to avoid the fiber filaments 21 from knotting and affecting the use effect.

[0037] The starting assembly 3 includes an electric cylinder 31 fixedly connected to the upper surface of the filter housing 1 via a bracket. A connecting frame 32 is fixedly connected to the output end of the electric cylinder 31. Both ends of the connecting frame 32 are fixedly connected to racks 33, and the two racks 33 are symmetrically arranged about the electric cylinder 31.

[0038] The adjustment assembly 4 includes a rotating shaft 41 disposed inside the filter housing 1. The rotating shaft 41 is rotatably connected to the upper end face of the filter housing 1 through a bearing. The bottom end of the rotating shaft 41 is fixedly connected to the upper surface of the rotating top plate 23. The top end of the rotating shaft 41 is fixedly connected to a gear 42, which meshes with a rack 33.

[0039] A backwashing mechanism is fixedly provided on the lower end face of the filter housing 1. The backwashing mechanism is used to perform air-water combined backwashing on the fiber filaments 21 when the filtration pressure difference or filtration time reaches a set value. The backwashing mechanism includes an air backwashing component 5 and a water backwashing component 6.

[0040] The air backwash assembly 5 includes multiple air supply pipes 51 fixedly connected to the lower end face of the filter housing 1. The inner walls of the output ends of the multiple air supply pipes 51 are fixedly connected to perforated plates 52. The perforated plates 52 can make the air evenly distributed, avoid excessive local airflow and damage the fiber filaments 21, and at the same time generate regular bubbles. Utilizing the scrubbing function and disturbance effect of the air bubbles, the fiber filaments 21 are strongly shaken and rubbed against each other, peeling off stubborn contaminants from the surface. An air inlet pipe 53 is provided at the bottom of the filter housing 1. The input ends of the multiple air supply pipes 51 are connected to the side wall of the air inlet pipe 53. An air outlet pipe 54 is fixedly connected to the upper end face of the filter housing 1. The air inlet pipe 53 is used to connect to the compressed air sent by the external Roots blower.

[0041] The water backwash assembly 6 includes multiple inlet and outlet water pipes 61 fixedly connected to the lower end face of the filter housing 1. The multiple inlet and outlet water pipes 61 are all connected to the interior of the columnar filter assembly 2. The bottom ends of the multiple inlet and outlet water pipes 61 are all fixedly connected to water supply pipes 62. The filter housing 1 is provided with inlet and outlet water pipes 63. The side ends of the multiple water supply pipes 62 are all connected to the side walls of the inlet and outlet water pipes 63. The side wall of the filter housing 1 is fixedly connected to a backwash outlet pipe 64.

[0042] In this embodiment, the electric cylinder 31, the Roots blower, and the external raw liquid pump (the conveying equipment for the liquid to be filtered), dosing pump (flocculator dosing pump and bactericide dosing pump) are all electrically connected to the external host computer and PLC control system to realize the fully automated control of the filtration and backwashing process without manual intervention. If multiple filters are configured, interlocking control can be realized to prevent two or more filters from backwashing at the same time. The filter must be started up if the raw water tank is not at a low level, and the backwash blower, raw liquid pump, and subsequent equipment all meet the operating requirements. Differential pressure transmitters need to be installed before and after the filter to monitor the operating status in real time.

[0043] The working principle of this invention is as follows: In standby mode, all equipment is turned off, and the valves in the original liquid inlet pipe 11, the inlet and outlet pipe 63, the backwash liquid outlet pipe 64, the air inlet pipe 53, the air outlet pipe 54, and the sewage pipe 14 are all closed. The fiber filament 21 is in a twisted state and does not move.

[0044] Filtration status: The valves of the raw liquid inlet pipe 11, the inlet / outlet water pipe 61, the water delivery pipe 62, and the inlet / outlet water pipe 63 are all open, and the fiber filaments 21 are in a tightened state. Subsequently, the raw liquid pump and the dosing pump are started. According to the raw water quality and treatment requirements, the electric cylinder 31 is started. After the electric cylinder 31 is started, the output end extends and retracts smoothly, driving the connecting frame 32 fixed to it to move left and right. The racks 33, which are symmetrically fixed at both ends of the connecting frame 32, move synchronously with the connecting frame 32. Since the racks 33 and the gears 42 of the adjusting component 4 mesh with each other, the movement of the racks 33 will drive the gears 42 to rotate synchronously. The gears 42 are fixed at the top of the rotating shaft 41, thereby driving the rotating shaft 41 to rotate smoothly on the upper surface of the filter housing 1. The bottom end of the rotating shaft 41 is fixedly connected to the rotating top plate 23 of the columnar filter component 2. The rotating top plate 23 rotates synchronously with the rotating shaft 41, which is fixed to the rotating top plate 23 and the annular A uniform torque is applied to the fiber filaments 21 between the base plates 22 to adjust the fiber filaments 21 to a suitable tension state until pores that meet the preset filtration accuracy are formed between the fiber filaments 21. After adjustment, the electric cylinder 31 stops and maintains the current state. The mechanical rotation adjustment mechanism locks the tension of the fiber filaments 21 to determine the filtration pores and filtration accuracy. Then, the raw water to be filtered is introduced into the filter housing 1 through the original liquid inlet pipe 11. The raw water flows through the columnar filter assembly 2. The fiber filaments 21 intercept suspended impurities, particulate matter and other pollutants in the water. The filtered clean water is discharged from the inlet and outlet pipes 61, water supply pipe 62 and outlet and outlet pipes 63 at the lower end of the filter housing 1. During filtration, the differential pressure transmitters installed before and after the filter monitor the filtration pressure difference in real time. The host computer and PLC control system record the filtration time synchronously. Once the preset threshold is reached, the backwashing program is triggered immediately.

[0045] Backwashing state: When the filter pressure difference reaches the preset value or the filtration time reaches the preset value, the backwashing mechanism is automatically activated. Through the combined action of air scrubbing and water rinsing, and in conjunction with the tension switching of the fiber filaments 21, the contaminants attached to the surface of the fiber filaments 21 are efficiently removed. First, the raw liquid pump, flocculant dosing pump, and bactericide dosing pump are turned off, the raw water input and dosing are stopped, the air outlet pipe 54 is kept open, and the electric cylinder 31 maintains the tension of the fiber filaments 21. Then, the original liquid inlet pipe 11 is closed. After the raw liquid in the filter has been filtered, the mechanical rotary regulating machine... The filter assembly is switched to the relaxed state of the fiber filaments 21 by the electric cylinder 31, which increases the gap between the fiber filaments 21 to facilitate the removal of pollutants. Then, the valves of the inlet and outlet pipes 63, the water inlet pipe 61, the water supply pipe 62, the backwash liquid outlet pipe 64, the air inlet pipe 53, the air outlet pipe 54, and the sewage discharge pipe 14 are opened. Backwash water is connected through the inlet and outlet pipes 63. The backwash water enters the columnar filter assembly 2 through the water supply pipe 62 and the water inlet pipe 1. The backwash water washes the fiber filaments 21 from bottom to top, thereby backwashing the fiber filaments 21 and washing away the loose pollutants.

[0046] Secondly, compressed air is introduced through the air inlet pipe 53. The compressed air is evenly dispersed through the air delivery pipe 51 and the perforated plate 52, forming regular bubbles. These bubbles then uniformly enter the columnar filter assembly 2, performing air backwashing on the relaxed fiber filaments 21. This loosens the contaminants attached to the surface of the fiber filaments 21. Combined with the water backwash assembly 6, the contaminants can be efficiently flushed away. The backwashing effect is excellent. During backwashing, the repeated tightening and loosening of the fiber filaments 21, the scrubbing and agitation of the air bubbles, and the flushing of the backwash water effectively remove stubborn contaminants from the surface of the fiber filaments 21. During the process, the waste gas and water vapor mixture generated is discharged in time through the air outlet pipe 54 fixedly connected to the upper end face of the filter housing 1 to avoid excessive internal pressure. The backwash wastewater carrying a large amount of pollutants is discharged through the backwash liquid outlet pipe 64 on the side wall of the filter housing 1 and flows into the wastewater treatment system. After the backwash is completed, the backwash mechanism stops working, the mechanical rotation adjustment mechanism starts again, the electric cylinder 31 moves to drive the fiber filament 21 back to the preset tension state, locks the filter pores, and the filter automatically switches back to the filtration operation mode to continue filtering raw water.

[0047] The operation and backwashing switching of the filter are mainly controlled by time signals and supplemented by differential pressure signals. The timing of each step of the filter control is determined according to the on-site debugging results. When the filter water production time reaches the set time, it switches to the backwashing step. If the differential pressure signal reaches the preset value, it also switches to the backwashing step.

[0048] Routine Maintenance: To ensure long-term stable operation of the equipment, regular simple routine maintenance is required. On the one hand, large particles and pollutants deposited at the bottom of the filter housing 1 should be discharged periodically through the drain pipe 14 on the lower end face of the filter housing 1 to prevent excessive accumulation of impurities from clogging the pipes or affecting the filtration effect. The drain pipe 14 can be opened and closed by an external control system during drainage without disassembling the equipment. On the other hand, when the equipment malfunctions, such as a significant decrease in filtration efficiency or pipe leakage, or when it is necessary to replace the fiber filaments 21 or repair internal components, all operating parts and related pipes of the equipment should be shut down first. After the water inside the equipment is drained and the pressure drops to normal pressure, the sealing cap 13 outside the cleaning port 12 should be unscrewed. The columnar filter assembly 2, mechanical rotation adjustment mechanism, backwash assembly, etc. inside the filter housing 1 can be inspected, maintained, or replaced through the cleaning port 12. The operation is convenient and does not require disassembling the entire equipment, which greatly reduces maintenance costs and time.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
