[0002] In all aspects of people's daily life, a large amount of sewage is inevitably generated. The composition of these sewage is complex and diverse. If it is not effectively treated and directly discharged, it will cause pollution to the water environment and affect people's normal life for a long time. Therefore, in order to reduce the impact of sewage on the water environment, water purification devices are often used.

[0003] A water purification device is a device that can effectively treat domestic sewage. Through multiple sewage treatment components installed inside, it can treat sewage in different processes, thereby removing pollutants in sewage, gradually improving water quality, and finally reaching the specified standard. During use, the water purification device will continuously adsorb and intercept impurities in sewage. Long-term use will lead to the accumulation of these impurities, which may easily cause clogging of the device. In order to avoid affecting the normal use of the device, it is necessary to regularly clean the impurities in the various components inside the device.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the scope of protection of the present invention. Example 1: like Figures 1 to 12As shown, the present invention provides a detachable modular water purification device, including a support plate 11, and a water inlet box 21 and a filter tank 31 are arranged above the support plate 11. The two are connected to the support plate 11 in a detachable manner by bolts, which is both stable and convenient for subsequent maintenance, overhaul or module replacement. The water inlet box 21 establishes a communication channel with the filter tank 31 by means of multiple groups of connecting pipes, thereby ensuring that the sewage can be smoothly transmitted between the two. Two groups of fixed frames 22 are arranged inside the filter tank 31, and the fixed frames 22 are rotatably connected to the filter tank 31. The first filter screen 41 and the second filter screen 42 are respectively installed on the fixed frame 22, and the first filter screen 41 is located above the second filter screen 42, which is conducive to the gradual filtering of the sewage. The filtering effect of the second filter screen 42 is greater than that of the first filter screen 41. The first filter screen 41 is mainly responsible for intercepting larger particle size suspended matter, impurity particles, etc. in the sewage, and plays a role in preliminary filtering. The second filter 42 has a finer mesh, which can effectively capture the tiny particles, colloidal substances and some organic macromolecules missed by the first filter 41, further improving the removal accuracy of impurities in sewage, thereby ensuring that the subsequent purification process can be carried out under higher quality water conditions, so that the efficiency of the entire purification system can be optimized. In order to ensure the continuous and efficient filtering performance of the filter, a cleaning component is provided in the filter tank 31, which can be in close contact with the first filter 41 and the second filter 42, and timely clean the impurities and dirt trapped during the filtration process. The filter element 12 provided on the support plate 11 is provided with multiple groups of biofilms 43. The filter element 12 constructs an effective connection passage with the filter tank 31 through the water pump 44, and the water pump 44 provides power support for the transmission of sewage, so that the sewage after preliminary filtration by the filter tank 31 can be transported to the filter element 12. Below the filter element 12, the water storage tank 23 and the filter element 12 are interconnected, and the purified water that has been deeply treated by the biofilm 43 can flow into the water storage tank 23 and be stored for subsequent use or further processing. Through the organic cooperation and combination of the water inlet tank 21, the filter tank 31 and the water storage tank 23, an efficient and practical modular structure is successfully constructed, which improves the flexibility, functionality and maintainability of the entire water purification device. The entire device is operated through an external control system. In daily maintenance or component failure, only the relevant components need to be disassembled. If one of the processing steps is damaged, it will not affect the use of other processes. The entire process does not require the operation of the entire device to be stopped, which reduces the maintenance time cost and avoids potential damage to other intact parts due to the disassembly of the entire machine, ensuring the stability and reliability of the device and effectively extending the service life of the device. like Figure 2 , Figure 5 , Figure 7 , Fig. 9As shown, the cleaning assembly includes two groups of screw rods 51, and multiple groups of connecting plates 32 are arranged on one side of the filter tank 31. The multiple groups of connecting plates 32 are distributed in a staggered manner. The bearings installed on them provide stable support points for the screw rods 51. The two ends of the screw rods 51 are inserted into the bearings and are arranged in an inclined manner, which creates good conditions for the effective movement of the subsequent cleaning brush 57. At one end of the screw rod 51, the connecting wheel 52 is firmly fixed, and the two groups of connecting wheels 52 are connected by a first transmission belt 53, forming a stable transmission system. On the mounting plate 33 on one side of the filter tank 31, the first motor 54 is installed, and its shaft end passes through the mounting plate 33 to connect with one of the groups of connecting wheels 52. When the first motor 54 is started, the power will be transmitted to the screw rod 51 through the synergistic effect of the connecting wheel 52 and the first transmission belt 53.

[0021] At the same time, the cleaning component also includes two sets of support cross bars 55. On one side of the filter tank 31, the through slot 34 provides a passage for the support cross bars 55 to pass through, and the slot 35 in the tank sets a running track for the sliding wheel 56 at the other end. After one end of the support cross bar 55 passes through the through slot 34, it is firmly sleeved on the screw rod 51. As the screw rod 51 rotates, the support cross bar 55 can move smoothly along a specific path. A cleaning brush 57 is provided at the bottom of the support cross bar 55. When the support cross bar 55 moves, the cleaning brush 57 can contact the first filter screen 41 and the second filter screen 42 respectively. Through the friction between the bristles and the surface of the filter screen, the impurities and dirt trapped in the pores of the filter screen are effectively cleaned, thereby ensuring that the filter screen is always in a good filtering state and ensuring that the filtering efficiency of the entire water purification device is continuously stable.

[0022] There are multiple groups of drain troughs 36 on one side of the filter tank 31, and a drain pipe 58 is provided on the support plate 11. The drain pipe 58 can ensure that impurities can pass smoothly. There are also multiple groups of card blocks 37 on one side of the filter tank 31. After the drain pipe 58 contacts the filter tank 31, it is clamped in the card block 37, which not only ensures the stability of the connection, but also facilitates installation and disassembly, and facilitates subsequent maintenance and cleaning work. A collection box 59 is detachably provided on the support plate 11. It is located directly below the drain pipe 58. The collection box 59 is connected to the filter tank 31 through the drain pipe 58 and the drain trough 36, forming a complete drain channel. When the cleaning component cleans the impurities on the first filter screen 41 and the second filter screen 42, these impurities will flow into the drain pipe 58 along the drain trough 36, and finally all gather in the collection box 59. The collecting box 59 can hold a certain amount of impurities, and its detachable feature allows it to be easily taken out for cleaning after it is full of impurities, thereby ensuring the continued normal operation of the entire sewage system and avoiding the performance and purification effect of the device being affected by the accumulation of impurities.

[0023] like Figure 2 , Figure 4 , Figure 5, Figure 8 As shown, two groups of connecting grooves 38 are provided inside the filter tank 31, and the connecting block 45 at the bottom of the fixed frame 22 is clamped in the connecting groove 38, so as to achieve a preliminary stable connection and positioning guide. At the same time, connecting holes are provided on the filter tank 31 and the connecting block 45, and two groups of connecting shafts 46 are respectively penetrated in the connecting holes, so as to ensure the firmness and reliability of the connection, so that the fixed frame 22 will not deviate or shake during the rotation process. The first transmission wheel 47 and the second transmission wheel 48 are welded to one end of the two groups of connecting shafts 46, respectively, to form an effective transmission structure. On the support plate 11, the second motor 13 is stably installed, and it is used as a power source to transmit power through the second transmission belt 14. The second transmission wheel 48 receives the power from the second motor 13, and is respectively linked with the first transmission wheel 47 by means of the second transmission belt 14, so as to drive the connecting shaft 46 to rotate, and finally realize the stable rotation of the fixed frame 22 in the filter tank 31, so as to adjust the position of the filter screen and cooperate with the cleaning component to clean up impurities, and ensure the continuous and efficient operation of the filter tank 31.

[0024] like Figure 6 , Fig. 9 As shown, limiting grooves 39 are provided on the two opposite inner sides of the filter tank 31, and limiting blocks 49 are provided at the corresponding positions on both sides of the fixing frame 22. The shape of the limiting blocks 49 matches the limiting grooves 39. When the fixing frame 22 is installed in the filter tank 31, the limiting blocks 49 can be clamped in the limiting grooves 39, which not only provides positioning for the fixing frame 22 and limits its displacement in the horizontal direction, but also ensures that the fixing frame 22 will not deviate or shake during the rotation process, so that the operation of the entire filtering system is more stable and reliable. There are multiple groups of fixed buckles 24 evenly distributed on the fixing frame 22, and the fixed buckles 24 are made of elastic material and have tightness and operability. The first filter screen 41 and the second filter screen 42 are respectively placed on the two groups of fixing frames 22 by clamping, and the fixed buckles 24 are clamped at the edges of the first filter screen 41 and the second filter screen 42, and the filter screens are firmly fixed on the fixing frame 22 to prevent them from loosening or displacement during water flow impact or filtering. At the same time, since the fixing frame 22 and the first filter screen 41 and the second filter screen 42 are detachably connected, when the filter screen needs to be cleaned, replaced or repaired, the filter screen can be conveniently removed from the fixing frame 22 by simply opening the fixing buckle 24, thereby improving the maintenance convenience and flexibility of the device, effectively reducing the maintenance cost and time cost, and ensuring the efficient and stable operation of the entire water purification device.

[0025] like Figure 2 , Fig.11As shown, a floating plate 61 is provided in the water inlet tank 21, and two groups of limit plates 25 are also provided in the water inlet tank 21. The floating plate 61 is located between the two groups of limit plates 25. The limit plates 25 limit the range of movement of the floating plate 61, so that it can only move smoothly in a specific area with the rise and fall of the water level. A liquid storage tank 62 for storing coagulants is installed on the water inlet tank 21. The liquid storage tank 62 is connected to the water inlet tank 21 through a connecting conduit, which ensures that the coagulant can flow smoothly into the water inlet tank 21, and can also avoid the adverse effects of excessive or too small flow on the mixing effect. The solenoid valve provided on the connecting conduit can control the amount of coagulant added, and an infrared sensor 63 is installed on the water inlet tank 21. Through the perception of the water level and other information in the water inlet tank 21 by the infrared sensor 63, combined with the real-time feedback of the floating plate 61, the amount of coagulant can be adjusted according to the amount of water in the water inlet tank 21, thereby laying a foundation for subsequent sewage purification treatment.

[0026] like Figure 2 , Fig.12 As shown, a support frame 65 and a stirring blade 66 are provided inside the water storage tank 23, and the support frame 65 is connected to the water storage tank 23, providing a support basis for the subsequent structure. A rotating bearing is installed on the support frame 65, and the stirring blade 66 is inserted into this rotating bearing, so that the stirring blade 66 can rotate, which is fully prepared for the subsequent stirring action. A sealing cover 67 is provided at the bottom of the support frame 65, and the sealing cover 67 is connected to the support frame 65 to form a relatively sealed sealing cavity. A turbine blade 68 is provided in the sealing cavity, and the turbine blade 68 is connected to the stirring blade 66.

[0027] A plurality of water outlet pipes 27 are arranged on one side of the water storage tank 23, and the water outlet pipes 27 are output channels of the water storage tank 23, which facilitate the outflow of the water body. At the same time, two groups of aeration pipes 28 are installed inside the water storage tank 23, and a plurality of air outlets are evenly distributed on the aeration pipes 28. A blower 29 is arranged on the other side of the water storage tank 23, and the blower 29 is connected to the aeration pipe 28 and the sealing cover 67 respectively through a connecting conduit, so that the sealing chamber and the blower 29 are connected and connected. When the blower 29 is started, a strong airflow will flow in along the connecting conduit. A part of the airflow will enter the aeration pipe 28, and then spray out from the plurality of air outlets on the aeration pipe 28, forming a large number of bubbles. These bubbles diffuse and move rapidly in the water body, which not only increases the oxygen content in the water body and promotes the oxidation reaction of the water body, but also can better suspend the impurities in the water body, which is convenient for subsequent treatment. The other part of the airflow will enter the sealed cavity formed by the sealing cover 67, driving the turbine blade 68 to rotate rapidly. The rotation of the turbine blade 68 will drive the stirring blade 66 to rotate together, thereby fully stirring the water in the water tank 23. This stirring action can make the water more uniform and allow oxygen to be more fully integrated into the water, further improving the effect and quality of water treatment in the water tank 23, making the function of the entire water tank 23 more complete and efficient; at the same time, multiple groups of ultraviolet lamps are also arranged in the water tank 23, and the specific wavelength ultraviolet rays emitted by them have extremely strong sterilization and disinfection capabilities. When the treated water is temporarily stored in the water tank 23, the ultraviolet rays can penetrate the water, destroy the DNA structure of microorganisms such as bacteria and viruses in the water, and make them inactive, thereby achieving efficient disinfection of the treated water, further improving the water quality safety, and ensuring that the purified water meets higher use standards or emission requirements. The ultraviolet lamp can use a GPH436T5L / 4P ultraviolet lamp.

[0028] A purification method of a detachable modular water purification device comprises the following steps: Step 1: Water inlet preparation; Slowly inject the sewage to be treated into the water inlet tank 21. During this process, pay attention to the position change of the floating plate 61. As the sewage is continuously injected, the water level gradually rises, and the floating plate 61 also rises accordingly, and the distance between it and the infrared sensor 63 gradually shortens. When the preset water level is reached, the infrared sensor 63 keenly detects the signal and quickly transmits the instruction to the solenoid valve, prompting the solenoid valve to open. At this time, the coagulant reagent stored in the liquid storage tank 62 will flow smoothly into the water inlet tank 21 along the connecting conduit. Under the stirring and mixing action of the water flow, the coagulant and the sewage are evenly integrated. This process is crucial. Through the action of the coagulant, the tiny suspended matter, colloids and other impurities in the sewage begin to condense with each other to form larger floc particles, which provides a good preliminary preparation for the subsequent filtration treatment and effectively improves the overall purification efficiency. Step 2: Filtration; The sewage pre-treated by the coagulant enters the filter tank 31 stably through the connecting pipe under the pressure difference. In the filter tank 31, the first filter screen 41 takes the lead in taking effect. Its mesh size is moderate and can effectively intercept the coagulated particles with larger particle sizes in the sewage and some impurities that have not been completely acted upon by the coagulant. The subsequent second filter screen 42 has a finer mesh and can further capture the tiny impurities, colloidal substances and some fine flocculent particles missed by the first filter screen 41, thereby performing a more refined preliminary filtration of the sewage. After the synergistic effect of these two layers of filter screens, the sewage after preliminary filtration is stored relatively clear at the bottom of the filter tank 31, waiting for the next step of deep treatment. Step 3: Multi-layer processing; The water pump 44 is turned on. The strong suction force of the water pump 44 accurately extracts the sewage at the bottom of the filter tank 31 into the filter element 12. When the sewage enters the filter element 12, it slowly flows through multiple groups of biofilms 43. These biofilms 43 are like bioreactors, and a large number of microbial flora are attached to their surfaces. When the sewage flows through the biofilms 43, the microorganisms use their own metabolic functions to decompose and transform the organic pollutants in the sewage as a nutrient source, further remove organic matter, nitrogen, phosphorus and other nutrients in the sewage, and achieve deep purification of the sewage. The purified water treated by the biofilm 43 flows smoothly into the water storage tank 23 below under the natural action of gravity, preparing for subsequent treatment steps. Step 4: Aeration treatment; The blower 29 is started, and the strong airflow generated by the blower 29 blows air into the aeration pipe 28 and the sealing cover 67 respectively; among them, a part of the wind directly rushes into the water body along the evenly distributed air outlets opened on the aeration pipe 28, forming a large number of tiny bubbles in the water. During the rising process of these bubbles, the contact area between the water body and the air is increased, which promotes the increase of the dissolved oxygen content in the water, and is conducive to the oxidation reaction of some reducing substances in the water; the other part of the wind enters the sealing cover 67 and blows toward the turbine blades 68; the turbine blades 68 rotate at a high speed driven by the wind, and drive the stirring blades 66 connected thereto to rotate synchronously; the rotation of the stirring blades 66 causes the water in the water storage tank 23 to form a strong water flow movement, which is fully in contact with the air, further enhancing the effect of oxidative decomposition of impurities in the water, such as further oxidizing and decomposing some organic macromolecules that are difficult to biodegrade into small molecules, thereby improving the degree of water purification; the water treated by aeration reaches a higher water quality standard and can be reused according to actual needs, such as for irrigation, industrial cooling, etc., or discharged into natural water bodies, without causing adverse effects on the environment; Step 5: Clean up impurities; When it is necessary to clean the first filter 41 and the second filter 42, the second motor 13 is started; the power generated by the operation of the second motor 13 is transmitted to the first transmission wheel 47 and the second transmission wheel 48 through the second transmission belt 14, thereby driving the fixed frame 22 to start to rotate slowly; during the rotation process, the fixed frame 22 gradually becomes inclined and contacts with the cleaning brush 57 in the cleaning assembly; at the same time, the sewage trough 36 is located at the bottom of the fixed frame 22, providing a channel for the discharge of impurities; then the first motor 54 is started, and the operation of the first motor 54 drives the screw rod 51 to start to rotate stably; because one end of the support cross bar 55 is sleeved on the screw rod 51, when the screw rod 51 Under the rotation of the support cross bar 55, the support cross bar 55 moves smoothly along the screw rod 51; and the cleaning brush 57 fixed at the bottom of the support cross bar 55 follows the moving trajectory of the support cross bar 55 to effectively sweep down the first filter screen 41 and the second filter screen 42; under the action of gravity, the swept impurities enter the collection box 59 in an orderly manner along the sewage trough 36 and the sewage pipe 58; the collection box 59 has a certain capacity and can temporarily store these impurities. After a certain amount of accumulation, the collection box 59 is disassembled and the impurities therein are uniformly cleaned and processed to ensure that the filtration system of the entire device always maintains a good working condition and continuously and efficiently performs water purification work. Embodiment 2: Based on the detachable modular water purification device and purification method provided in the first embodiment of the present application, the second embodiment of the present application proposes a detachable modular water purification device and purification method. This second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below.

[0029] like Figure 3 , 12As shown, a water inlet tank 21 is provided with a water inlet groove 26, and a fence 64 is provided above the support plate 11. The fence 64 is stuck in the water inlet groove 26. In order to further ensure its stability and firmness, the fence 64 is also connected to the water inlet tank 21 by fixing bolts. The fence 64 can play a certain filtering and blocking role, preventing some larger impurities or foreign objects from entering the water inlet tank 21, thereby ensuring the smooth progress of the subsequent processing flow. A floating plate 61 is provided in the water inlet tank 21, and two groups of limiting plates 25 are also provided in the water inlet tank 21. The floating plate 61 is located between the two groups of limiting plates 25. The limiting plates 25 limit the range of movement of the floating plate 61, so that it can only move smoothly in a specific area with the rise and fall of the water level. A liquid storage tank 62 for storing coagulants is installed on the water inlet tank 21. The liquid storage tank 62 is connected to the water inlet tank 21 through a connecting conduit, which ensures that the coagulant can flow smoothly into the water inlet tank 21 and can also avoid excessive or insufficient flow rates from having adverse effects on the mixing effect. The solenoid valve provided on the connecting conduit can control the amount of coagulant added. An infrared sensor 63 is installed on the water inlet tank 21. The infrared sensor 63 senses information such as the water level in the water inlet tank 21, and combined with the real-time feedback of the floating plate 61, the amount of coagulant can be adjusted according to the amount of water in the water inlet tank 21, thereby laying the foundation for subsequent sewage purification treatment.

[0030] The difference between the second embodiment and the first embodiment is that a water inlet groove 26 is provided on the water inlet box 21, and the fence 64 is clamped in the water inlet groove 26, and is further connected to the water inlet box 21 by fixing bolts. When the water body carries various impurities or foreign matter and attempts to enter the water inlet box 21, the fence 64 can effectively intercept and block those larger impurities or foreign matter, and can prevent these substances that may have an adverse effect on the subsequent treatment process from entering the water inlet box 21, thereby providing a reliable guarantee for the subsequent treatment process. Because once a large number of larger impurities or foreign matter enter, it may cause the equipment to be blocked, damaged, or affect the treatment effect and efficiency. The remaining conditions are consistent with the first embodiment, so this embodiment will not be repeated.

[0031] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the second section of the above exemplary embodiment.
