Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water treatment device. Background Art

[0002] In the field of industrial wastewater treatment, existing water treatment technologies typically utilize horizontally positioned filter devices for wastewater purification. These devices present numerous issues during the treatment process, impacting the effectiveness of wastewater purification. First, due to structural design limitations, horizontally positioned filters result in a shorter path for wastewater flowing through the filter media, and uneven flow distribution. Especially during high-flow treatment, the rapid flow of wastewater concentrates kinetic energy in certain areas of the filter media, leading to overuse of some media and underutilization of media in other areas. This uneven flow distribution impairs the effective retention of impurities, ultimately resulting in suboptimal purification results.

[0003] Secondly, existing industrial wastewater treatment equipment typically uses only a single type of filter element with a uniform pore size, making it unable to effectively filter suspended solids and fine particles of varying particle sizes simultaneously. For example, when treating wastewater containing large amounts of sediment and oil, while larger sediment particles can be initially retained, fine oil and particulate matter can still pass through the filter element, causing the effluent quality to fail to meet emission standards. Furthermore, a single filter element structure is prone to clogging when treating wastewater with high levels of suspended solids. This is especially true after long periods of operation, when a large amount of dirt accumulates on the filter element surface, requiring frequent replacement or cleaning, which increases the operating and maintenance costs of the equipment.

[0004] Existing wastewater treatment systems also suffer from low wastewater discharge efficiency. Although some systems are equipped with drain outlets, poorly designed outlets prevent waste from accumulating inside the filter and draining away. This often results in residual waste inside the filter, hindering the subsequent purification process. These issues render existing technologies inefficient in treating industrial wastewater, making it difficult to meet increasingly stringent environmental standards and the requirements for efficient treatment.

[0005] Therefore, in the field of industrial wastewater treatment, existing technologies have significant deficiencies in terms of water flow uniformity, filtration effectiveness, multi-level filtration capabilities, and convenient wastewater discharge. There is an urgent need for an improved water treatment device that can achieve uniform water flow distribution, possess multiple filtration functions, and facilitate wastewater discharge, in order to improve the overall efficiency and reliability of wastewater treatment. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a water treatment device.

[0007] The technical solution of the present utility model is: a water quality treatment device, comprising an impurity removal component, an electrochemical reaction component and a collection component connected in sequence, the impurity removal component consists of a vertically placed third long cylinder and a filter arranged inside the third long cylinder, both ends of the third long cylinder have openings, and the upper end of the third long cylinder is covered with a second port portion for supporting the filter, the lower end of the third long cylinder is covered with a first bottom wall, the second port portion has a first water outlet, and the third long cylinder has a second water outlet; the filter consists of a filter container and a first filter element and a second filter element arranged inside the filter container, the upper end of the filter container is detachably covered with the third port portion, the second filter element is sleeved on the first filter element and the second filter element is folded by a plurality of annular bodies to produce geometric corrugated folds.

[0009] Note: The mesh size of the first filter element is within the range of 200μm to 600μm, which can ensure its filtering function. At the same time, the third long cylinder made of transparent material can enable the impurity removal component to be observed in time during use, so as to understand the contamination status of the filter in real time and perform timely replacement and cleaning.

[0010] Furthermore, the filter container is composed of a pipe and a mounting portion and a bottom component arranged at the upper and lower ends of the pipe. The pipe is made of transparent material and has a drainage hole connected to the second water outlet. The center of the bottom component is provided with a drainage outlet and a drainage valve connected to the drainage outlet.

[0011] Note: The main body of the filter container made of transparent material can facilitate observation of the usage of the first filter element and the second filter element, facilitate real-time understanding of the contamination of the filter, and timely replacement and cleaning.

[0012] Furthermore, the third port portion is composed of a flange and a fourth cylindrical body, the center of the flange is provided with a water inlet connected to the first water port and a water inlet valve connected to the water inlet, the outer diameter of the fourth cylindrical body is the same as the inner diameter of the first filter element, and is used to clamp the second filter element bent in the folded edge portion of the first filter element.

[0013] Note: By controlling the outer diameter of the fourth cylindrical body so that it can meet the requirements of the folded edge portion for clamping the second filter element, the second filter element can be prevented from falling off the first filter element, thereby improving the stability of the filter.

[0014] Furthermore, the annular body is elastic and is a seamless annular structure or a seam-containing annular structure.

[0015] Description: The setting of the annular body can make the second filter element have geometric corrugated folds, thereby having a larger surface area and extending the cleaning interval.

[0016] The beneficial effects of the utility model are:

[0017] (1) The water treatment device of the present invention adopts a vertically placed long cylinder component design, so that the water to be purified passes through the filter from top to bottom.

[0018] (2) The water treatment device of the present invention adopts a double-layer filter element structure, wherein the first filter element has a porous side wall structure, and the second filter element has a mesh structure on the outer wall; the double-layer filter element can not only effectively intercept particles of different sizes, but also ensure a finer filtering effect; the built-in first filter element is in close contact with the second filter element, ensuring that the water flow can intercept fine impurities to the maximum extent when passing through the multi-layer filter medium, thereby achieving a higher level of water purification; the mesh structure of the second filter element can also remove pollutants.

[0019] (3) The water treatment device of the present invention is provided with a special discharge port at the bottom of the third long cylinder for sewage discharge. The position design of the discharge port ensures that the dirt inside the filter can be discharged quickly and thoroughly, reducing the blockage problem caused by the accumulation of dirt. This not only extends the service life of the filter element, but also reduces the maintenance frequency and improves the overall operating efficiency of the equipment.

[0020] (4) The filter in the water treatment device of the present invention is designed to be detachable, especially the filter element, which makes the replacement and maintenance of the filter element more convenient. When the filter element needs to be cleaned or replaced, it is only necessary to simply remove the port blocking part, which reduces the maintenance workload and improves the operability of the equipment.

DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0030] like Figure 4As shown, in some embodiments, the present invention provides a water treatment device 101. The water treatment device 101 comprises an electrochemical reaction section 1, a collection section 3, and an impurity removal section 5. The electrochemical reaction section 1 purifies water through an electrochemical reaction, converting dissolved deposits in the water into solid deposits, thereby removing these deposits from the water. The collection section 3 receives and stores deposits that fall from the electrochemical reaction section 1. The impurity removal section 5 is used to screen the water to be purified that enters the electrochemical reaction section 1.

[0031] The electrochemical reaction section 1 comprises a first, open-ended cylinder 7, a first port 8, two electrode bodies 9, two power transmission sections 11, a water inlet 13, and a drain hole 15. The first cylinder 7 is positioned vertically. The first port 8 covers the upper end of the first cylinder 7. The electrode bodies 9 are used to perform an electrochemical reaction on the purified water and are evenly distributed within the first cylinder 7. The power transmission sections 11 extend through and are supported by the first port 8. These power transmission sections 11 are electrically connected to and support the electrode bodies 9.

[0032] The power supply unit 17 is positioned above the first port 8 and connected to the power transmission unit 11 via a wire 12, applying voltage to the electrode body 9. The power supply unit 17 is a DC power supply with switchable polarity. In the illustrated example, the voltage polarity can be manually adjusted by turning a key 18. In this example, the electrode body 9 and the power transmission unit 11 each have a pair. Because the power supply unit 17 is close to the power transmission unit 11, the wire 12 between the power supply unit 17 and the power transmission unit 11 is relatively short.

[0033] The water inlet 13 is connected to the interior of the first long tube 7, through which the purified water flows into the interior of the first long tube 7. The water drain hole 15 is also connected to the interior of the first long tube 7, through which the purified water flows out of the first long tube 7. In the illustrated example, both the water inlet 13 and the water drain hole 15 are provided on the side wall of the first long tube 7.

[0034] The collecting part 3 includes a second long cylinder 19 with openings at both ends, an outflow hole 21 and a discharge valve 23. The second long cylinder 19 is similar to the first long cylinder 7 and is placed vertically in the illustrated example. The upper end of the second long cylinder 19 is connected to the lower end of the first long cylinder 7, and its internal space is connected to the internal space of the first long cylinder 7. The outflow hole 21 is located at the lower end of the second long cylinder 19 and is used to discharge the accumulation 43 at the lower end of the second long cylinder 19. The outflow hole 21 is opened on the second bottom wall 75 covering the lower end of the second long cylinder 19. The discharge valve 23 is installed on the second bottom wall 75 to control the opening and closing of the outflow hole 21 for discharging the accumulation. In the illustrated example, the discharge valve 23 and the second bottom wall 75 are an integral structure.

[0035] The impurity removal section 5 consists of a third long tube 25 with two open ends, a filter 27, a second port 29, a first water inlet 31, and a second water inlet 33. The third long tube 25, similar to the first long tube 7 and the second long tube 19, is vertically positioned in the illustrated example. The filter 27 is located within the third long tube 25 and is used to filter impurities from the water to be purified. The second port 29 supports the filter 27 and covers the upper end of the third long tube 25.

[0036] The first water inlet 31 communicates with the interior of the third elongated tube 25, allowing water to flow into the third elongated tube 25 through the first water inlet 31. The second water inlet 33 is also connected to the interior of the third elongated tube 25, allowing water to flow out of the third elongated tube 25 through the second water inlet 33. In the illustrated example, the first water inlet 31 is located on the second end portion 29, while the second water inlet 33 is located on the sidewall of the third elongated tube 25.

[0037] The impurity removal section 5 is also equipped with a first valve 37, a discharge port 38, and a second valve 39. The first valve 37 is mounted on the second port portion 29 and controls the opening and closing of the first water port 31. The discharge port 38 is located at the lower end of the third elongated cylinder 25 and is used to discharge accumulated waste. It is located on the first bottom wall 40. The second valve 39 is connected to the first bottom wall 40 to control the opening and closing of the discharge port 38. The water inlet 13 of the electrochemical reaction section 1 is connected to the second water port 33 of the impurity removal section 5 via a water outlet pipe 41.

[0038] The water to be purified enters the third long cylinder 25 through the first water inlet 31 of the impurity removal section 5, and after being filtered by the filter 27, enters the interior of the first long cylinder 7 of the electrochemical reaction section 1 through the second water inlet 33, the outlet pipe 41, and the water inlet 13. Microorganisms, sludge, dust, and other contaminants in the water to be purified that have not been removed by the electrochemical reaction are removed by the filter 27 before entering the electrochemical reaction section 1. The water to be purified undergoes electrochemical reaction treatment in the electrode body 9 within the first long cylinder 7 to remove scale, and is finally discharged to the exterior of the water treatment device 101 through the drain hole 15. For example, in the cooling water circulation path of the water storage tank of a cooling tower, the first water inlet 31 can be connected upstream and the drain hole 15 can be connected downstream, thereby providing the water treatment device 101 within the circulation path. Therefore, the water treatment device 101 can be used for purification applications such as cooling water circulation.

[0039] Describing the electrochemical reaction purification process in more detail, when voltage is applied to the electrode body 9 via the power supply unit 17, scale materials in the water to be purified within the first long cylinder 7 are adsorbed onto the electrode body 9, which serves as the negative electrode, and accumulate in the form of scale. For example, the polarity of the applied voltage can be changed by turning the key 18, thereby peeling the scale from the original negative electrode to the electrode body 9, which is now the positive electrode. The new negative electrode body 9 continues to adsorb and accumulate scale materials. In this way, the water to be purified is purified in the electrochemical reaction section 1 and discharged to the outside of the water treatment device 101 through the drain hole 15. In the illustrated example, the conduit 45 connected to the drain hole 15 is connected to the side wall of the second long cylinder 19.

[0040] The deposits 43 peeled off from the electrode body 9 settle to the bottom of the second long cylinder 19 and reach the outflow hole 21. When the deposits 43 accumulate to a certain amount, the discharge valve 23 is opened to discharge the water to be purified and the deposits 43 in the first and second long cylinders 7 and 19 to the outside of the water treatment device 101.

[0041] In the water treatment device 101, the electrochemical reaction part 1 and the collection part 3 hold the water to be purified in the first long cylinder 7 and the second long cylinder 19 arranged in series in a longitudinal direction. By appropriately extending the longitudinal (i.e., vertical) length of these first long cylinder 7 and the second long cylinder 19, it is possible to ensure that a sufficient volume of water to be purified can be accommodated. In this way, when the water treatment device 101 is installed, the volume of the water to be purified can be guaranteed without occupying a large amount of lateral space (i.e., in a direction parallel to the ground). In particular, by extending the longitudinal length of the second long cylinder 19, the accumulated deposits 43 can be kept at a position farther away from the electrode body 9 without occupying too much lateral space. In addition, the third long cylinder 25 of the impurity removal part 5 is similar to the first long cylinder 7 and the second long cylinder 19, and also adopts a longitudinal posture, so the installation of the impurity removal part 5 does not need to occupy a large amount of lateral space.

[0042] The first long tube 7 is composed of a first cylindrical body 47 and mounting parts 49 embedded at both ends thereof. Similarly, the second long tube 19 is composed of a second cylindrical body 70 and mounting parts 71 embedded at both ends thereof. The mounting part 49 at the lower end of the first long tube 7 is docked with the expanded diameter portion (i.e., flange portion) of the mounting part 71 at the upper end of the second long tube 19, and is detachably fastened by a connecting fitting 73. This allows the two first long tubes 7 and the second long tube 19 to be detachably connected to each other. By rotating the bolt, the connecting fitting 73 can easily fasten the two mounting parts 49 and 71 (such as Figure 5 After the two first long cylinders 7 and the second long cylinder 19 are separated, their respective maintenance and cleaning operations can be performed. For example, the accumulated deposits 43 (see Figure 4 ) is crushed with a rod-shaped object and discharged from the outflow hole 21.

[0043] like Figure 6 As shown, the mounting member 49 at the lower end of the first long tube 7 and the mounting member 71 at the upper end of the second long tube 19 are detachably fastened via a connecting fitting 73. Simultaneously, the mounting member 49 at the upper end of the first long tube 7 and the first port portion 8 covering the upper end of the first long tube 7 are also detachably fastened via the same connecting fitting 73. Furthermore, the second bottom wall 75 covering the lower end of the second long tube 19 and provided with the outflow hole 21 is also detachably fastened to the mounting member 71 at the lower end of the second long tube 19 via the same connecting fitting 73.

[0044] Back to Figure 4 The third long cylinder 25 of the impurity removal part 5 has the same structure as the second long cylinder 19 of the collection part 3. That is, the third long cylinder 25 is also composed of a third cylindrical body 77 and mounting parts 79 embedded at both ends. The mounting part 79 at the lower end of the third long cylinder 25 is detachably fastened to the first bottom wall 40 via the connecting fitting 73. Similarly, the mounting part 79 at the upper end of the third long cylinder 25 is detachably fastened to the second port portion 29 via the connecting fitting 73. It should be noted that Figure 4 Not shown in the figure is a connecting fitting 73. For connecting the first long tube 7, the second long tube 19, and the connecting fitting 73 between the first long tube 7, the second long tube 19, the third long tube 25 and other components, fasteners such as bolts or nuts can also be used.

[0045] It is preferred that the first cylinder 7 be at least partially made of a transparent material to facilitate internal observation. For example, the first cylindrical body 47 can be made of a transparent plastic such as polyvinyl chloride, acrylic resin, or ABS resin. This allows the accumulation of deposits on the electrode body 9 to be observed from the outside, and based on the visual inspection results, it can be determined whether the DC voltage polarity needs to be reversed. Similarly, the second cylinder 19 is also preferably made at least partially of a transparent material. For example, the second cylindrical body 70 can be made of a transparent plastic such as polyvinyl chloride. This allows the state of the deposits 43 accumulated at the bottom of the second cylinder 19 to be observed from the outside, and based on the observation results, it can be determined when to discharge the deposits 43 through the outflow hole 21. In addition, the third cylinder 25 is also preferably made at least partially of a transparent material. For example, the third cylindrical body 77 can be made of a transparent plastic such as polyvinyl chloride. This allows the accumulation of deposits in the filter 27 arranged in the third cylinder 25 to be observed from the outside, and it can be determined when to clean the filter 27 accordingly.

[0046] The outlet pipe 41 has a detachable joint (not shown), or partially uses a flexible tubular member such as a rubber tube, so that the electrochemical reaction part 1 and the impurity removal part 5 can be installed or removed separately. Similarly, the first valve 37 of the impurity removal part 5 (see Figure 4 ) and the outlet pipe 45 connected to the electrochemical reaction part 1, which is preferably connected to the outlet pipe of the purified water flow path through a detachable joint or a flexible tubular component.

[0047] like Figure 4 As shown, the upper end of electrode body 9 is fixedly connected to the lower end of power transmission unit 11 by fastener 81. In the example shown, fastener 81 is a combination of a bolt and nut. Power transmission unit 11 and the screw are not platinum-plated, so even when immersed in water, they do not cause an electrode reaction like platinum-plated electrode body 9.

[0048] like Figure 1 and 2 As shown, the filter 51 (corresponding to the filter 27 ) includes a filter container 151 , a third port portion 160 , a first cylindrical filter element 57 with upper and lower ends opened, and a second cylindrical filter element 58 .

[0049] The filter container 151 is a cylindrical container with an opening facing upwards, and its side wall is composed of a transparent pipe 152. An annular mounting portion 159 is provided at its opening, and a drainage hole 153 is provided on the pipe 152. The drainage hole 153 is connected to the outlet pipe 66 (corresponding to the Figure 4 The bottom of the filter container 151 is composed of a bottom plate and a lower annular side plate. The installation part 159 of the filter container 151 and the pipe 152 are similar to Figure 1 The third long tube 25 in the tubing 152 is secured at its upper end to the mounting portion 159 and at its lower end to the bottom member 155. The mounting portion 159 and bottom member 155 can be made of chlorinated polyvinyl chloride. A drain port 157 is provided in the center of the bottom plate of the bottom member 155 and is connected to the drain valve 55.

[0050] The third port portion 160 is used to detachably cover the open upper end of the filter container 151. The third port portion 160 includes a flange 161, a fourth cylindrical body 165 and an inlet valve 53. The flange 161 is disc-shaped and is fixed to the mounting portion 159 of the filter container 151 by bolts or other fasteners to cover the opening. Figure 2 and Figure 5 ) simplifies assembly and disassembly, facilitating user maintenance. A water inlet 163 is located in the center of flange 161 and is connected via inlet valve 53. A fourth cylindrical body 165 is integrally connected to the lower surface of flange 161 and extends downward. Its outer diameter is approximately the same as the inner diameter of first filter element 57. Flange 161 and fourth cylindrical body 165 can be made of chlorinated polyvinyl chloride.

[0051] The first filter element 57 is a cylindrical structure with a porous structure, and both the upper and lower ends are open. The first filter element 57 is usually a grid structure made of plastic and has a certain degree of rigidity. The second filter element 58 is a cylindrical structure with an open upper end and a closed lower end. Its mesh structure is as flexible as cloth and can be folded, wrinkled or stretched. The mesh size is in the range of 200μm to 600μm, with 400μm being taken to ensure its filtering function. The second filter element 58 is usually made of a plastic mesh material, such as polyethylene or nylon, and its diameter is closely matched with the outer periphery of the first filter element 57, and sufficient length is reserved at the upper end for easy coverage. Figure 1 The geometric corrugated pleats of the second filter element 58 are shown.

[0052] Fourth cylindrical body 165 of third port portion 160 is inserted from the upper end of first filter element 57 and grips folded edge 59 of second filter element 58. The outer diameter of fourth cylindrical body 165 is designed to grip second filter element 58, thereby preventing it from falling out. After fourth cylindrical body 165 is secured, flange 161 of third port portion 160 can be removably connected to mounting portion 159 of filter container 151.

[0053] The purified target water enters the interior of the fourth cylindrical body 165 from the water inlet 163 through the water inlet valve 53, and is then filtered through the grid gaps of the first filter element 57 and the mesh of the second filter element 58. The second filter element 58 is responsible for removing pollutants. The purified target water after filtering is accumulated in the filter container 151 and then sent to the electrochemical reaction part 1 (see Figure 4 ).

[0054] The filtered pollutants accumulate on the inner surface of the second filter element 58, forming a deposit. When the accumulation reaches a certain level, it will cause the second filter element 58 to become clogged, thereby reducing the filtering effect. The transparent tubing 152 allows the user to observe the accumulation of deposits in the second filter element 58. When the deposit is large, the user can close the water inlet valve 53, remove the third port 160, remove the first filter element 57 from the fourth cylindrical body 165, and further remove the second filter element 58 for cleaning. Due to its pleated design, the second filter element 58 has a larger surface area, which extends the cleaning interval.

[0055] By opening the drain valve 55 connected to the bottom member 155, the purified water stored in the filter container 151 can be drained, thereby cleaning the filter container 151. The user can observe the cleaning status of the filter container 151 through the transparent tubing 152. After cleaning, the filter 51 can be reassembled in reverse order. The see-through function of the tubing 152 facilitates user maintenance.

[0056] The second filter element 58 may be a fully flexible mesh structure or a partially flexible mesh structure. For example, the bottom portion may not have a mesh structure, and a small portion of the side may not have a mesh structure.

[0057] Figure 2 (e) and (f) show how the annular body 83 is arranged around the side of the second filter element 58 to promote the adhesion of deposits. This was discovered during the trial production process. Deposits refer to sticky substances containing scale, including bacteria and plants and animals. The number of annular bodies 83 is selected according to the length of the second filter element 58. The annular body 83 is elastic and can be pressed against the side of the second filter element 58. The annular body 83 can be seamless (such as Figure 2 (e)), there may also be seams (as shown in Figure 2 (f) The seams can also have gaps. When using only the second filter element 58, deposits typically adhere thinly to its surface. However, after installing the annular body 83, the deposits more easily adhere to the annular body 83, thereby improving capture efficiency. The deposits may contain fungi. Existing thick filter screens have difficulty capturing these fungi.

[0058] Figure 3 The schematic diagram of the structure of the ring body 83 is shown. Figure 3 In the annular body 83 in (a), a tubular sponge is inserted into the hollow portion of the tubular fabric or nonwoven fabric. Figure 3 In the annular body 83 in (b), a polyethylene corrugated tube is inserted into the hollow portion of the mesh tube. The mesh tube can be made of a plastic mesh or a metal mesh. Alternatively, the annular body 83 can be formed using only the mesh tube without inserting the corrugated tube. Figure 3 In the annular body 83 in (c), a plurality of polyethylene wires are inserted into the hollow part of the tubular sponge. All of these structures can be made into linear components first and then connected to form the annular body 83. For example, Figure 3 The annular body 83 in (a) is completed by sewing the two ends of the outer layer of cloth or non-woven fabric; Figure 3 The annular body 83 in (b) is completed by connecting the two ends of the outer mesh tube; Figure 3 The annular body 83 in (c) is completed by connecting the two ends of the inner polyethylene thread. Figure 3 The annular bodies 83 in (a) to (c) all have moderate elasticity and are designed to allow purified water to pass through with low resistance.
