Description

Technical Field

[0001] This invention relates to the field of water filtration technology, and more particularly to a continuous integrated water treatment device. Background Technology

[0002] Water filtration refers to the process of separating or removing suspended particulate matter, colloidal substances, organic pollutants, microorganisms, and some dissolved impurities from water through physical, chemical, or physicochemical methods, so that the water quality meets production, living, or discharge standards. This technology typically involves components such as filter media, filter units, drive structures, and supporting piping systems. By constructing stable separation channels or interception interfaces, solid-liquid separation or pollutant removal is achieved. Water filtration is necessary in social production and daily life. On the one hand, large amounts of wastewater generated during industrial production often contain suspended solids, grease, metal ions, or organic residues. If discharged directly without treatment, it will pollute the water environment. On the other hand, drinking water, agricultural irrigation water, and circulating cooling water all have specific requirements for water quality. If the water contains silt, algae, or microorganisms, it will not only affect the stability of equipment operation but may also endanger human health. Existing mechanical filtration methods physically trap water through filter screens, filter cloths, sand layers, or multi-media filter layers, relying on particle size differences to achieve solid-liquid separation. Examples include sand filters, multi-media filters, and precision cartridge filters. These methods have relatively simple structures and are suitable for removing suspended particles and larger-diameter impurities. However, when treating water with high turbidity or containing viscous impurities, the inner filter layer is prone to clogging and screen sticking, requiring frequent backwashing or replacement of filter media. For example, patent document publication number CN116621378A discloses a water supply and drainage device with impurity filtration function, which also reflects that before water is used, it needs to undergo coarse filtration and subsequent multi-layer fine filtration. Such filters require cleaning and replacement.

[0003] Therefore, how to provide a continuous integrated water treatment device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One objective of this invention is to provide a continuous integrated water treatment device. This invention utilizes the principle of gravity descent to effectively improve the actual service life and practical effect of the filter screen while ensuring filtration efficiency, preventing screen clogging, and reducing the frequency of shutdown backwashing and filter media replacement.

[0005] According to an embodiment of the present invention, a continuous integrated water treatment device includes a base and an outer body assembly fixedly mounted on one side above it. The outer body assembly includes a cylinder and an inlet end seat fixed above it by a sealing cap. Fan-shaped filter plates are arranged inside the cylinder for water filtration. Pressure relief ports and drain ports are respectively opened on the upper and lower sides of the cylinder. The bottom of the cylinder is sealed on a grid assembly. The bottom of the grid assembly is sealed to a lower end, and the bottom of the lower end is sealed to a sludge outlet end seat. The outer body assembly, grid assembly, and fan-shaped filter plates are generally perpendicular to the ground. The grid assembly includes an annular mesh plate, an assembled mesh plate, and a sealing seat. The annular mesh plate is fixed above the sealing seat. The assembled mesh plate is fixed to one side of the annular mesh plate by bolts. There are two sets of fan-shaped filter plates. The two sets of fan-shaped filter plates are pressed together by the annular mesh plate and the assembled mesh plate and are arranged inside the cone formed by the annular mesh plate and the assembled mesh plate. A water storage layer is formed between the cylinder and the annular mesh plate and the assembled mesh plate. A cleaning mechanism is provided at the axial position formed by the two sets of fan-shaped filter plates. The cleaning mechanism is used to clean the surface of the fan-shaped filter plates.

[0006] Preferably, the cylinder body is sealed and fixed above the sealing seat, the lower end is set at the bottom of the sealing seat, and a narrowing mechanism is also provided inside the lower end. The sealing seat and the lower end have openings near the axis of the cleaning mechanism, and the bottom of the cleaning mechanism is rotatably set in the sewage outlet seat.

[0007] Preferably, the narrowing mechanism further includes an annular plate, six sets of narrowing plates, and an electric telescopic rod. The electric telescopic rod, which is rotatably mounted outside the lower end via a rotating seat, has its output end driving the annular plate to rotate within the lower end via a control lever.

[0008] Preferably, six sets of shrink plates are arranged in a ring array above the annular plate. The top of the shrink plates is limited and slides in the groove on the bottom surface of the sealing seat by a limiting slider, and the bottom of the shrink plates is limited and slides in the pin groove opened on the surface of the annular plate by a toggle pin. There are six sets of pin grooves, which are aligned with each other.

[0009] Preferably, the cleaning mechanism further includes a spindle and a vortex shaft. The bottom of the spindle is threadedly connected to the threaded hole at the top of the vortex shaft via a threaded post. An adjustment plate is fixed at the top of the spindle. The bottom of the vortex shaft passes through the sewage outlet seat via a sealing bushing. The bottom of the vortex shaft is connected to the output shaft of the drive motor via a reducer. Both the drive motor and the reducer are fixed on the base.

[0010] Preferably, a locking plate is threadedly connected to the side of the sewage outlet seat, and the end of the locking plate is aligned with the shaft body below the vortex shaft.

[0011] Preferably, a spiral blade is fixedly provided on the surface of the shaft rod, and a water-facing end is seamlessly connected between the shaft rod and the spiral blade near the upper part of the spiral blade. The sides of both the spiral blade and the water-facing end are in contact with the surface of the fan-shaped filter plate.

[0012] Preferably, the spiral diameter of the spiral blade gradually increases from top to bottom, and the pitch of the spiral blade at the water-facing end is greater than the pitch of the spiral blade.

[0013] Preferably, the vortex shaft is located inside the sludge outlet seat, and one side of the sludge outlet seat is connected to the slag outlet and the return pipe respectively through a three-way valve.

[0014] Preferably, the output end of the active motor is connected to the pump, and the pump outlet is connected to the inlet end seat via a connecting pipe.

[0015] The beneficial effects of this invention are: This invention utilizes the principle of gravity descent. When water carrying impurities or flocculent matter enters the inner side of the cylinder, the liquid level gradually rises inside the cylinder. Then, through sedimentation combined with the inclined fan-shaped filter inner mesh, low-speed filtration is achieved, which can effectively ensure the cleanliness of the fan-shaped filter inner mesh and prevent the fan-shaped filter from becoming clogged. This invention provides a cleaning mechanism between two sets of fan-shaped filter plates. The spiral diameter of the spiral blades on the surface of the shaft rod matches the tilting posture of the fan-shaped filter plates, so that the shaft rod can scrape and wash the inner mesh of the fan-shaped filter plates during rotation, while also assisting impurities to settle. This invention sets the shaft rod and the vortex shaft in a threaded connection, so that when the edge of the spiral blade wears, the adjusting plate at the top of the shaft rod can be rotated to drive the threaded transmission between the shaft rod and the vortex shaft, so that the spiral blade is slightly lifted, thus making it suitable for long-term scraping operations. This invention, through its constriction mechanism, can work with the pressure relief port, water inlet end seat, and drain port to control the liquid level and pressure inside the cylinder. The pressure value can effectively achieve backwashing inside the cylinder, while controlling the liquid level can also achieve filtration conditions suitable for different situations (higher liquid level, larger filtration area of ​​the fan-shaped filter, and higher filtration efficiency).

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] refer to Figures 1-7The system includes a base 1 and an outer body assembly 2 fixedly mounted on one side above it. The outer body assembly 2 includes a cylinder 21 and an inlet end seat 26 fixed above it by a sealing cap. A fan-shaped filter 7 is installed inside the cylinder 21 for water filtration, meaning water passes through the surface material structure of the fan-shaped filter 7 from the inside to the outside. A pressure relief port 22 and a drain port 23 are respectively opened on the upper and lower sides of the cylinder 21. The pressure relief port 22 and the drain port 23 are respectively connected to pipelines and closed control valves to control the pressure inside the cylinder 21. The bottom of the cylinder 21 is sealed on a grid assembly 6. The bottom of the grid assembly 6 is sealed to a lower end 24, and the bottom of the lower end 24 is sealed to a sludge outlet end seat 25. These sealing connections can be achieved through threaded connections. The components are assembled together, which facilitates the replacement of the internal fan-shaped filter elements 7. The entire device is installed vertically during use, ensuring that the outer body assembly 2, the grid assembly 6, and the fan-shaped filter elements 7 are perpendicular to the ground. This verticality effectively reduces direct contact between impurities, particles, and flocculent matter and the inner surface of the fan-shaped filter elements 7. The grid assembly 6 includes an annular mesh plate 61, an assembled mesh plate 62, and a sealing seat 63. The annular mesh plate 61 is directly welded to the sealing seat 63. The assembled mesh plate 62 is bolted to one side of the annular mesh plate 61, allowing for an assembled connection between the assembled mesh plate 62 and the annular mesh plate 61. Two sets of fan-shaped filter elements 7 are connected by pressing the annular mesh plate 61 and the assembled mesh plate 62 together. The fan-shaped filter 7, placed inside the cone formed by the annular mesh plate 61 and the assembled mesh plate 62, has a fan-shaped actual shape when unfolded in a plane. Simultaneously, when the two sets of fan-shaped filter 7 are curled into a cone shape, they can better fit the inner surfaces of the annular mesh plate 61 and the assembled mesh plate 62, resulting in an overall cone-shaped shape. In this way, impurities and flocculent matter carried by the water inside the fan-shaped filter 7 will converge downwards under the action of gravity sedimentation, while the water can be filtered through the fan-shaped filter 7 to the outside. It is important to note that this effect requires controlling the water pressure inside and outside the fan-shaped filter 7 to prevent the water flow from carrying impurities into excessive contact with the inner wall of the fan-shaped filter 7. A water storage layer 27 is formed between the cylinder 21 and the annular mesh plate 61 and the assembled mesh plate 62, satisfying the requirement of water storage within a certain space. A cleaning mechanism 9 is provided at the axial position formed by the two sets of fan-shaped filter plates 7. The cleaning mechanism 9 is used to clean the surface of the fan-shaped filter plates 7, further reducing the formation of a paste-like substance by impurities on the inner mesh of the fan-shaped filter plates 7. Specifically, the cylinder 21 is sealed and fixed above the sealing seat 63. In practice, the two are sealed by inserting a sealing ring. The lower end 24 is located at the bottom of the sealing seat 63. A narrowing mechanism 8 is also provided in the lower end 24. The narrowing mechanism 8 is used to control the actual water flow rate and ensure the stability of the water pressure inside the cylinder 21. The sealing seat 63 and the lower end 24 have openings near the axial position of the cleaning mechanism 9. The bottom of the cleaning mechanism 9 is rotatably set in the sewage outlet seat 25. At the same time, the rod of the cleaning mechanism 9 passes through the sealing seat 63 and the lower end 24.

[0025] Example 1: When treating water containing silt, algae, or impurities, the drain outlet 23 is closed, and the narrowing mechanism 8 is adjusted to its minimum. Water then enters the mesh cage formed by the annular mesh plate 61 and the assembled mesh plate 62 through the inlet end seat 26. Filtration is achieved by the filter surface composed of two sets of fan-shaped filter plates 7. The filtered water remains in the water storage layer 27. As the inflow increases, the liquid level in the cylinder 21 gradually rises to the middle of the cylinder 21. At this point, the pressure relief port 22 is closed, and the flow rate of the drain outlet 23 is adjusted, allowing clean water to be discharged through the drain outlet 23. The annular mesh plate 61 and the assembled mesh plate 62, including the fan-shaped filter plates 7 clamped at their inner walls, have an overall conical shape and are perpendicular to the ground (horizontal plane). Therefore, impurities in the water will sink due to gravity when the water pressure inside and outside the fan-shaped filter 7 is the same. During the sinking process, by controlling the liquid discharge rate of the actual drain outlet 23, it can be ensured that impurities will not clog the inner mesh surface of the fan-shaped filter 7 excessively, until the impurities gather at the constriction position above the constriction mechanism 8, thereby ensuring that the water pressure inside the cylinder 21 remains in a relatively stable state. On this basis, it is only necessary to make the water inlet volume of the inlet end seat 26 equal to the water discharge volume of the drain outlet 23 plus the water loss at the constriction mechanism 8 (the effect is best when the water discharge volume of the drain outlet 23 is equal to the water loss at the constriction mechanism 8), so as to achieve a stable sinking effect of impurities inside the fan-shaped filter 7 and prevent silt, algae or debris from clogging the mesh surface of the fan-shaped filter 7.

[0026] refer to Figure 4 and Figure 5The contraction mechanism 8 also includes an annular plate 81, six sets of contraction plates 84, and an electric telescopic rod 83. The electric telescopic rod 83, rotatably mounted outside the lower end 24 via a rotating seat, drives the annular plate 81 to rotate within the lower end 24 via a control lever 82 when receiving a system signal. The control lever 82 is a protruding part fixed to the side of the annular plate 81. The rod body slides within a groove extending through the side of the lower end 24, and its end is rotatably connected to the ear seat at the output end of the electric telescopic rod 83 via a convex shaft, ensuring a movable relationship. Thus, after the electric telescopic rod 83 is driven, the cylindrical part is rotatably connected to the lower end 24. During the extension and retraction of the output end, the rotation of the control lever 82 will drive the annular plate 81 to rotate within the lower end 24. The six sets of contraction plates 84 are arranged in a circular array above the annular plate 81, and the top of the contraction plates 84 is limited by a control lever. The slider 85 is limited to sliding in the groove on the bottom surface of the sealing seat 63. The bottom of the shrink plate 84 is limited to sliding in the pin groove 87 opened on the surface of the annular plate 81 by the actuating pin 86. There are six sets of pin grooves 87, which are aligned with each other with the shrink plate 84. Therefore, when the annular plate 81 rotates, since the top of the shrink plate 84 is limited by the limiting slider 85 and the bottom groove of the sealing seat 63, the pin groove 87 on the surface of the annular plate 81 pushes the actuating pin 86, and the shrink plate 84 as a whole will be displaced in the direction of the axis of the annular plate 81, thus expanding or shrinking the constriction formed by the six sets of shrink plates 84.

[0027] Example 2: The expansion or contraction of the constriction formed by the six sets of constriction plates 84 can change the liquid flow rate at that point. When the six sets of constriction plates 84 completely close the opening at that point, particulate impurities will accumulate in the gaps of the opening, thus blocking the opening. This effect is generally used to meet the filtration of large volumes of water, so that the liquid level inside the cylinder 21 reaches the highest point, maximizing the filtration area of ​​the fan-shaped filter 7. By controlling the size of the opening here, the water inside the cylinder 21 can be allowed to flow out. This, combined with the drainage from the drain outlet 23 and the water intake from the inlet end seat 26, controls the actual liquid level inside the cylinder 21. This allows the filtration area of ​​the fan-shaped filter 7 to be used according to the actual situation, effectively extending the overall service life of the fan-shaped filter 7. The filtration position on the lower surface of the fan-shaped filter 7 is used first. Later, when aging or other problems occur, the liquid level inside the cylinder 21 is raised in sequence, and the filtration position in the middle or upper part of the fan-shaped filter 7 is used for subsequent filtration operations.

[0028] refer to Figure 4 , Figure 6 and Figure 7The cleaning mechanism 9 also includes a spindle 91 and a vortex shaft 92. The bottom of the spindle 91 is threadedly connected to the top of the vortex shaft 92 via a threaded post. Therefore, when the threads of the spindle 91 and the vortex shaft 92 twist, the overall length of the spindle 91 and the vortex shaft 92 will change. An adjusting plate 93 is fixed at the top of the spindle 91. The bottom of the vortex shaft 92 passes through the discharge end seat 25 via a sealing bushing. The bottom of the vortex shaft 92 is connected to the output shaft of the drive motor 3 via a reducer 4. After the drive motor 3 starts, the output shaft is reduced by the reducer 4, driving the vortex shaft 92 and the spindle 91 to rotate at a low speed inside the discharge end seat 25. It should be noted that the vortex shaft 92 and the spindle 91 are threadedly connected to prevent the vortex shaft 92 from twisting. In the rotating state, a helical transmission occurs between the vortex shaft 92 and the spindle 91. The threaded connection between the vortex shaft 92 and the spindle 91 needs to be equipped with a locking positioning structure. This structure can be a pin that passes through the spindle shaft 92 and inserts into the spindle 91, or it can be a spring clamping structure. This is the existing matching connection, so it will not be described in detail here. The active motor 3 and the reducer 4 are both fixed on the base 1. The side of the sewage outlet seat 25 is threaded with a locking plate 94. The end of the locking plate 94 is aligned with the shaft body below the vortex shaft 92. When the locking plate 94 is manually rotated, the end of the locking plate 94 will press against the vortex shaft 92. At this time, the threaded transmission between the spindle 91 and the vortex shaft 92 can be driven by the adjusting plate 93, changing the relative height position of the spindle 91 between the two sets of fan-shaped filter plates 7. A spiral blade 95 is fixedly mounted on the surface of the shaft 91. A water-facing end 96 is seamlessly connected between the shaft 91 and the spiral blade 95 near the upper part of the shaft 91. The sides of both the spiral blade 95 and the water-facing end 96 are in contact with the surface of the fan-shaped filter 7. The function of the water-facing end 96 is to increase the contact area with the water, assisting the rotational drive effect of the end of the shaft 91. After the water contacts the surface of the water-facing end 96, it provides an auxiliary rotational effect to the shaft 91, thus ensuring that the shaft 91 can effectively scrape and wash the inner screen of the fan-shaped filter 7 from both top and bottom. The spiral diameter of the spiral blade 95 gradually increases from top to bottom, and the pitch of the water-facing end 96 is larger than the pitch of the spiral blade 95.

[0029] Example 3: The spindle 91 can change its relative height position between the two sets of fan-shaped filter plates 7, and the spiral blades 95 on the surface of the spindle 91 will also change their height position synchronously. Since the spiral diameter of the spiral blades 95 gradually increases from top to bottom (the diameter increases linearly here, consistent with the inclination of the fan-shaped filter plates 7, the annular mesh plate 61, and the assembled mesh plate 62), the edge of the spiral blades 95 will contact the inner mesh surface of the fan-shaped filter plates 7. The edge of the spiral blades 95 can be made of flexible contact material such as silicone to prevent scratching the fan-shaped filter plates 7 during rotation. Therefore, under normal circumstances, the spindle 91... 1. Rotating the spiral blade 95 scrapes the inner mesh surface of the fan-shaped filter 7, causing the flocculated material attached to the surface to separate from the mesh surface. The characteristics of the spiral blade also help push the flocculated material downward to settle. After a long time, when the edge of the spiral blade 95 wears and the cleaning effect is poor, the adjusting plate 93 can be twisted to change the thread position between the shaft rod 91 and the vortex shaft 92. This causes the spiral blade 95 to move slightly upward between the two sets of fan-shaped filter 7, so that the edge of the spiral blade 95 contacts the inner mesh surface of the fan-shaped filter 7 again, thus ensuring that the filtration efficiency of the fan-shaped filter 7 is maintained for a long time.

[0030] refer to Figure 1 , Figure 3 and Figure 4 The vortex shaft 92 is located inside the sludge outlet seat 25. A vortex-shaped pusher plate is also provided on the surface of the vortex shaft 92. During rotation, it can push impurities such as mud and sand into the opening of the sludge outlet seat 25. One side of the sludge outlet seat 25 is connected to the slag outlet and the return pipe via a three-way valve. The output end of the drive motor 3 is connected to the pump 5, and the outlet of the pump 5 is connected to the inlet seat 26 via a connecting pipe.

[0031] In this implementation scheme, after the constriction mechanism 8 port is expanded, the accumulated mud or flocculent matter will fall into the sludge outlet seat 25. As the vortex shaft 92 rotates, the vortex-shaped push plate on the surface of the vortex shaft 92 can effectively push such impurities into the outlet of the sludge outlet seat 25. By setting a three-way valve at the outlet of the sludge outlet seat 25, the sludge outlet seat 25 is connected to the sludge outlet when sludge discharge is required, and the sludge outlet seat 25 is connected to the return pipe when liquid return is required, so as to achieve high-speed liquid return.

[0032] Working principle: During the preparation phase, the pressure relief port 22 and the inlet end seat 26 are opened, and the drain port 23 is closed. Then, the electric telescopic rod 83 is activated. The electric telescopic rod 83 drives the annular plate 81 to rotate in the lower end 24 through the control rod 82, so that the pin groove 87 on the surface of the annular plate 81 can push the actuating pin 86 under the shrink plate 84. Since the top of the shrink plate 84 slides with the bottom surface of the sealing seat 63 through the limiting slider 85, the six sets of shrink plates 84 move closer to each other and align. At this time, the shrinkage formed by the six sets of shrink plates 84 is the smallest. Subsequently, by starting the active motor 3, the output shaft of the active motor 3 drives the pump 5 to operate, sending the water to be treated from the inlet end seat 26 into the inner side of the cylinder 21. At this time, the water is between the two sets of fan-shaped filter plates 7. After being filtered by the fan-shaped filter plates 7, the clean water is stored in the water storage layer 27, so the water level in the cylinder 21 gradually rises. The liquid level is controlled according to the actual required treatment volume. After reaching a certain height, the pressure relief port 22 is closed, the drain port 23 is opened, and the flow rate of the inlet end seat 26 and the drain port 23 is controlled so that the water inlet of the inlet end seat 26 = the water discharged from the drain port 23 + the loss at the constriction mechanism 8, thus completing the basic filtration operation. The annular mesh plate 61, the assembled mesh plate 62, and the two sets of fan-shaped filter plates 7 are conical. Therefore, impurity particles will sink under this stable pressure environment, preventing excessive contact with the inner mesh of the fan-shaped filter plates 7 and causing clogging. During the process of pumping water into the pump, the output shaft of the active motor 3 also drives the vortex shaft 92 to rotate at low speed through the reducer 4. The vortex shaft 92 drives the upper shaft rod 91 to rotate between the two sets of fan-shaped filter plates 7. The rotation effect will simultaneously drive the spiral blades 95 on the surface of the shaft rod 91 to scrape the inner mesh of the fan-shaped filter plates 7 back and forth, further preventing flocculent matter from contacting the inner mesh of the fan-shaped filter plates 7 and assisting impurities to sink. After the filtration operation is completed, the six sets of shrink plates 84 are opened by the electric telescopic rod 83. Before this, the drain port 23 and the water inlet end seat 26 are closed. Air is pumped into the cylinder 21 through the pressure relief port 22. The pressure relief port 22 can be connected to an external air pump after the operation is completed. At this time, there is a certain air pressure above the liquid surface in the cylinder 21. The air pressure pushes the water to backwash the fan-shaped filter 7. At the same time, when the water rushes into the vortex shaft 92, the vortex push plate on the surface of the auxiliary vortex shaft 92 realizes that the impurities and flocculent matter are discharged from the sewage outlet end seat 25 port. After prolonged filtration, the edges of the spiral blades 95 become worn. At this point, the locking plate 94 can be rotated to press its end against the shaft below the vortex shaft 92. Then, the adjusting plate 93 at the top of the shaft rod 91 is rotated to drive the threaded transmission between the shaft rod 91 and the vortex shaft 92. This causes the shaft rod 91 to move the spiral blades 95 upward a short distance between the two sets of fan-shaped filter plates 7, allowing the edges of the spiral blades 95 to effectively contact the inner mesh surface of the fan-shaped filter plates 7 again, thus ensuring the long-term scraping effect of the spiral blades 95 on the inner mesh surface of the fan-shaped filter plates 7.
