Description

Technical Field

[0001] This utility model relates to the field of pretreatment system technology, and in particular to a pretreatment system for water quality testing. Background Technology

[0002] The stable operation of water quality testing equipment is a crucial prerequisite for ensuring the accuracy and continuity of test data. Currently, in practical applications, various water quality testing equipment typically requires extracting water samples from the water body to be tested through water pipelines for analysis. However, natural water bodies or industrial wastewater often contain a large number of impurities, such as suspended particulate matter, silt, and fibrous debris. These impurities can easily cause a series of problems during water sample transportation and testing, adversely affecting the normal operation of the testing equipment.

[0003] On the one hand, if impurities in the water enter the testing equipment directly with the water sample, they may clog the testing channels or sensor components, leading to equipment malfunction and damage. This not only increases maintenance costs but also interrupts water quality testing, affecting the integrity of monitoring data. On the other hand, the water pump used to extract water samples is a crucial power component in the water quality testing system, and its long-term stable operation directly affects the reliability of the water intake process. During actual water intake, impurities in the water are easily sucked into the pump, potentially causing impeller jamming and wear, leading to decreased pump performance or even damage. Simultaneously, when impurities clog the pump inlet or internal flow channels, the pump load increases, operating under overload conditions for extended periods, further accelerating pump wear and shortening its lifespan. When the pump is clogged or damaged due to wear, the entire water quality testing system will be unable to extract water normally, causing testing to halt and significantly hindering water quality monitoring. Therefore, this invention proposes a pretreatment system for water quality testing. Utility Model Content

[0004] The purpose of this invention is to address the problems in the background technology where existing water quality testing equipment is prone to clogging of the testing equipment channels and damage to sensors due to impurities in natural or industrial discharged water, resulting in high maintenance costs and easy interruptions in testing operations. This invention proposes a pretreatment system for water quality testing.

[0005] The technical solution of this utility model is as follows: A pretreatment system for water quality testing includes two sets of water pumps; an inlet pipe connected to the output end of one set of water pumps, and a connecting pipe connecting the inlet pipe to the output end of the other set of water pumps; an algae removal mechanism connected to one side of the inlet pipe via a first flexible hose, the algae removal mechanism being used to eliminate the influence of algae in the water on the water quality testing results; a temporary storage tank connected to the algae removal mechanism via a second flexible hose, the temporary storage tank containing multiple sets of multi-parameter probes; a filter assembly installed in the temporary storage tank, the filter assembly being connected to a suction device to send the filtered water to the water quality testing equipment; and a backwashing mechanism connected to one end of the filter assembly, the backwashing mechanism being used to backwash the filter assembly to prevent clogging of the filter components.

[0006] Optionally, the input ends of the two sets of water pumps are respectively connected to water supply pipes.

[0007] Optionally, a pressure relief valve is installed at one end of the water inlet pipe, and a pressure relief pipe is connected to the pressure relief valve.

[0008] Optionally, the algae removal mechanism includes a flow tube, on the side of which a first connector and a second connector are installed. The first connector is connected to a first flexible tube, and the second connector is connected to a second flexible tube. An algae removal UV lamp is provided on the side of the second connector away from the first connector. The algae removal UV lamp is installed at one end of the flow tube, and the flow tube is open at the end facing the algae removal UV lamp and closed at the other end.

[0009] Optionally, a drain pipe is connected to the bottom of the temporary storage box, and a solenoid valve is installed on the drain pipe.

[0010] Optionally, the filter assembly includes an installation tube fixedly connected to a temporary storage box, the installation tube passing through one side of the temporary storage box, a fixing block fixedly connected to one end of the installation tube inside the temporary storage box, a conical cavity formed in the fixing block, a filter screen disposed on the side of the conical cavity away from the installation tube, a pressure ring disposed on the side of the fixing block away from the installation tube, multiple sets of screws passing through the pressure ring, the screws being threadedly connected to the fixing block, and a sealing ring disposed between the pressure ring and the filter screen.

[0011] Optionally, multiple sets of suction cylinders are installed on the fixing block, and the multiple sets of suction cylinders are arranged in a ring array.

[0012] Optionally, the backwashing mechanism includes a power source electrically connected to an air pump, and a fourth flexible hose is connected between the output end of the air pump and the mounting pipe.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This utility model sets up two sets of water pumps to achieve backup switching of the water intake power components. When any set of water pumps is blocked by debris or damaged by wear, the other set can be started immediately to continue working, avoiding interruption of the water intake process. At the same time, the pressure relief valve on the water inlet pipe can automatically release pressure when the water pressure in the pipeline is too high, preventing pipeline rupture, further ensuring the stable operation of the entire pretreatment system and reducing the risk of testing work being interrupted.

[0015] Furthermore, the algae removal UV lamp in the algae removal mechanism can effectively kill algae in the water sample, avoiding algae interference with the test results. The filter screen of the filter component can trap suspended impurities in the water, preventing impurities from entering the water quality testing equipment and causing blockage and damage. In conjunction with the air pump of the backwashing mechanism, backwashing is achieved by high-speed gas impacting the filter screen. The filter screen can be cleaned without disassembly to remove blockages and impurities, extending the service life of the filter screen, reducing the frequency of component replacement, and reducing equipment maintenance costs.

[0016] In summary, this utility model can ensure the normal operation of the testing equipment, improve the reliability of the water quality testing system, reduce maintenance costs, and ensure the continuity of testing. Attached Figure Description

[0031] Example

[0032] like Figure 1 As shown, the present invention proposes a pretreatment system for water quality testing, including two sets of water pumps 1. The input ends of the two sets of water pumps 1 are respectively connected to water pipes 11. With the setting of two sets of water pumps 1, if any one set fails, the other set can be started to work, ensuring the smooth progress of subsequent water quality testing.

[0033] Furthermore, the aforementioned pretreatment system also includes an inlet pipe 2 connected to the output end of one set of water pumps 1. A connecting pipe 21 connects the inlet pipe 2 to the output end of another set of water pumps 1. When both sets of water pumps 1 are started, they deliver water into the inlet pipe 2 and then further. A pressure relief valve 22 is installed at one end of the inlet pipe 2, and a pressure relief pipe 23 is connected to the pressure relief valve 22. When the water pressure in the inlet pipe 2 is too high, the pressure is relieved through the pressure relief valve 22, and at the same time, the water is discharged through the pressure relief pipe 23.

[0034] Furthermore, the aforementioned pretreatment system also includes an algae removal mechanism 4 connected to one side of the inlet pipe 2 via a first flexible hose 3. The algae removal mechanism 4 is used to eliminate the influence of algae in the water on water quality testing results. The algae removal mechanism 4 includes a flow pipe 41, with a first connector 42 and a second connector 43 installed on its side. The first connector 42 is connected to the first flexible hose 3, and the second connector 43 is connected to the second flexible hose 5, allowing water to sequentially pass through the first flexible hose 3, the flow pipe 41, and the second flexible hose 5 into the temporary storage tank 6. An algae-removing UV lamp 44 is installed on the side of the second connector 43 away from the first connector 42. The algae-removing UV lamp 44 is installed at one end of the flow pipe 41, with the flow pipe 41 open at one end facing the algae-removing UV lamp 44 and closed at the other end. After the algae-removing UV lamp 44 is activated, the water flows from the first connector 42 to the second connector 43, facilitating the removal of algae in the water.

[0035] Furthermore, the aforementioned pretreatment system includes a temporary storage tank 6 connected to the algae removal mechanism 4 via a second flexible hose 5. A drain pipe 61 is connected to the bottom of the temporary storage tank 6, through which residual water and impurities from backwashing are discharged. A solenoid valve 62 is installed on the drain pipe 61, controlling its opening and closing to ensure water remains in the temporary storage tank 6 during pumping. Multiple sets of multi-parameter probes 7 are installed in the temporary storage tank 6, which can monitor key water quality parameters such as pH, dissolved oxygen, and conductivity in real time, providing preliminary data for subsequent water quality testing.

[0036] For details, please refer to Figure 2The aforementioned pretreatment equipment also includes a filter assembly 8 installed in the temporary storage tank 6. The filter assembly 8 is connected to a suction device, which is a water pump, to deliver the filtered water to the water quality testing equipment. The filter assembly 8 includes an installation pipe 81 fixedly connected to the temporary storage tank 6. The installation pipe 81 passes through one side of the temporary storage tank 6, and a fixing block 82 is fixedly connected to one end of the installation pipe 81 inside the temporary storage tank 6. A conical cavity is formed in the fixing block 82. A filter screen 83 is provided on the side of the conical cavity away from the installation pipe 81. The filter screen 83 is used to filter the water entering the conical cavity and prevent impurities from entering the water quality testing equipment. A pressure ring 84 is provided on the side of the fixing block 82 away from the installation pipe 81. Multiple sets of screws 85 pass through the pressure ring 84. The screws 85 are threadedly connected to the fixing block 82, and the pressure ring 84 is fixed by the screws 85. A sealing ring 86 is provided between the pressure ring 84 and the filter screen 83. After installation, the pressure ring 84 compresses the filter screen 83 through the sealing ring 86, fixing the position of the filter screen 83 and preventing water impurities from passing through the edge of the filter screen 83. Multiple suction cylinders 87 are installed on the fixing block 82, arranged in a ring array. One end of the suction cylinder 87 is located in the conical cavity, and the other end of the suction cylinder 87 is fixedly connected to a third connector 88. The third connector 88 is connected to the suction device through a third hose 89. After the suction device is started, suction is performed through the third hose 89, the third connector 88, and the suction cylinder 87, creating a negative pressure in the conical cavity. As a result, the water in the temporary storage tank 6 enters the conical cavity through the filter screen 83 and is filtered as it passes through the filter screen 83.

[0037] Furthermore, the aforementioned pretreatment equipment includes a backwashing mechanism 9 connected to one end of the filter assembly 8. The backwashing mechanism 9 is used to backwash the filter assembly 8 to prevent clogging of the filter components. The backwashing mechanism 9 includes a power supply 91, which is electrically connected to an air pump 92, supplying power to the air pump 92. A fourth flexible hose 93 is connected between the output end of the air pump 92 and the mounting pipe 81. After the air pump 92 is started, it blows air into the mounting pipe 81 through the fourth flexible hose 93. The high-speed gas directly impacts the filter screen 83 after passing through the mounting pipe 81, impacting the impurities clogging the filter screen 83 and ensuring the subsequent filtration effect.

[0038] In this embodiment, when the detection process is started, either of the two sets of water pumps 1 can be started. The water to be tested enters the water pump 1 through the water supply pipe 11. After being pressurized by the water pump 1, it is collected through the connecting pipe 21 and transported to the inlet pipe 2. When the water pressure in the inlet pipe 2 is too high, the pressure relief valve 22 automatically opens, and the excess water sample is discharged through the pressure relief pipe 23 to avoid damage to the pipeline due to excessive pressure.

[0039] When the algae-removing UV lamp 44 is activated, the water sample entering the inlet pipe 2 flows into the flow pipe 41 of the algae removal mechanism 4 through the first flexible hose 3. As the water sample flows from the first connector 42 to the second connector 43, the ultraviolet light emitted by the algae-removing UV lamp 44 kills the algae in the water sample, eliminating the interference of algae on subsequent test results. The algae-removed water sample is then transported to the temporary storage tank 6 through the second connector 43 and the second flexible hose 5.

[0040] The multi-parameter probe 7 inside the temporary storage tank 6 monitors key parameters of the water sample in real time, such as pH, dissolved oxygen, and conductivity, providing preliminary reference for subsequent testing. Simultaneously, the suction equipment is activated, drawing suction from the suction cylinder 87 via the third hose 89 and the third connector 88. This creates negative pressure in the conical cavity within the fixed block 82. Under this negative pressure, the water sample in the temporary storage tank 6 is filtered through the filter screen 83, trapping suspended impurities. The filtered water sample then enters the conical cavity and is transported via the suction cylinder 87, the third connector 88, and the third hose 89 to the water quality testing equipment for analysis.

[0041] When filter screen 83 becomes clogged, causing a decrease in filtration efficiency, the backwashing mechanism 9 is activated. Power supply 91 supplies power to air pump 92, and the high-speed gas generated by air pump 92 is delivered to installation pipe 81 through the fourth hose 93. After entering the conical cavity through installation pipe 81, the high-speed gas directly impacts filter screen 83, blowing off the impurities trapped on filter screen 83. After backwashing is completed, solenoid valve 62 is opened, and the residual water sample and blown-off impurities in temporary storage tank 6 are discharged through drain pipe 61, completing the backwashing operation and ensuring the subsequent filtration effect of filter screen 83.

[0042] If one of the water pumps 1 fails during operation, it can be immediately switched to another water pump 1 to continue working, ensuring that the water intake process of the entire pretreatment system is uninterrupted and the water quality testing is continuous.

[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
