It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1-2 The figure shows a self-cleaning and energy-saving water sample filtering device realized by the utility model. As shown in the figure, the filtering device is composed of a pressure chamber module 1, a water inlet valve 2, a cleaning valve 3, a drain valve 4, a water outlet valve 5, a water pump 6, a pipeline 7 and a pressure relief valve 8.

[0019] The pressure chamber module 1 is respectively connected to the water inlet valve 2 , the cleaning valve 3 , the drain valve 4 , the water outlet valve 5 and the pressure relief valve 8 through pipelines 7 .

[0020] At the same time, the water inlet valve 2 is connected to the pressure chamber module 1 and the water pump 6 through the pipeline 7 respectively. The water pump 6 provides power to supply water to the pressure chamber module 1 through the water inlet valve 2. In this way, the raw water enters the pressure chamber module 1 through the tangential water inlet 1-1 at a specific water pressure.

[0021] The cleaning valve 3 is connected to the pressure chamber module 1 through the pipeline 7 for cleaning the pressure chamber module 1 ; tap water passes through the cleaning valve 3 , through the tangential cleaning port 1 - 2 , and enters the pressure chamber module 1 to clean the pressure chamber module 1 .

[0022] The drain valve 4 is connected to the pressure chamber module 1 through a pipeline 7 and is used to drain the water in the pressure chamber module 1 . The raw water passes through the drain port 1 - 3 and is emptied through the drain valve 4 .

[0023] The water outlet valve 5 is connected to the pressure chamber module 1 through a pipeline 7, and the water outlet valve 5 prepares a water sample suitable for the water quality equipment.

[0024] The pressure relief valve 8 is connected to the pressure chamber module 1 and the water inlet valve 2 through a pipeline 7 .

[0025] Refer to Figure 1 and Figure 2As shown, the pressure chamber module 1 is provided with a tangential water inlet 1-1, a tangential cleaning port 1-2, a drain port 1-3 and a water outlet 1-4, wherein the water inlet 1-1 is connected to the water inlet valve 2 through a pipeline 7, the tangential cleaning port 1-2 is connected to the cleaning valve 3 through a pipeline 7, the drain port 1-3 is connected to the drain valve 4 through a pipeline 7, and the water outlet 1-4 is connected to the water outlet valve 5 through a pipeline 7.

[0026] At the same time, the pressure chamber module 1 has an upper cavity 1-5, a lower cavity 1-6, a filter plate 1-7 and an impeller 1-8. The upper cavity 1-5 and the lower cavity 1-6 are arranged up and down and connected by bolts through a sealing ring. The impeller 1-8 is installed on the filter plate 1-7, and the filter plate 1-7 is arranged between the upper cavity 1-5 and the lower cavity 1-6; the impeller 1-8 extends from the upper and lower sides of the filter plate 1-7 into the upper cavity 1-5 and the lower cavity 1-6.

[0027] In conjunction with the accompanying drawings, the use process of the utility model includes the following:

[0028] The first step is to open the water inlet valve 2, the water outlet valve 5 and the pressure relief valve 8, and close the cleaning valve 3 and the drain valve 4 at the same time, and then start the water pump 6. The raw water passes through the water inlet valve 2, and by adjusting the pressure relief valve 8, the raw water enters the pressure chamber module 1 through the tangential water inlet 1-1 at a specific water pressure. The raw water forms a vortex in the pressure chamber module 1 to drive the impeller 1-8 to rotate and flush the filter plate 1-7. At the same time, the raw water passes through the filter plate 1-7 and the water outlet 1-4, and prepares the water sample required by the water quality equipment from the water outlet valve 5 for sampling and analysis by the water quality equipment, thereby realizing the self-cleaning and energy-saving effects of anti-blocking and continuous sample preparation of the water sample filtration device;

[0029] The second step is to close the water pump 6 and the cleaning valve 3, and open the drain valve 4, so that the raw water in the pressure chamber module 1 passes through the drain port 1-3 and is emptied through the drain valve 4;

[0030] The third step is to close the water pump 6, the water inlet valve 2, the water outlet valve 5 and the pressure relief valve 8, and open the cleaning valve 3 and the drain valve 4 at the same time. Then the tap water passes through the cleaning valve 3, passes through the tangential cleaning port 1-2, and enters the pressure chamber module 1. The tap water forms a vortex in the pressure chamber module 1 to drive the impeller 1-8 to rotate and flush the filter 1-7. The residue on the filter 1-7 and the lower cavity 1-6 is discharged outward through the water outlet 1-4 and the drain valve 4 along with the tap water;

[0031] Step 4: Close the water pump 6, the water inlet valve 2, the water outlet valve 5, the pressure relief valve 8 and the cleaning valve 3, and open the drain valve 4 at the same time. The residual water in the pressure chamber module 1 passes through the water outlets 1-4 and is drained through the drain valve 4.

[0032] Step 5: Repeat the first to fourth steps in a cycle, thereby achieving the functions of self-cleaning, anti-clogging, and continuous sample preparation for the water sample filter, achieving high timeliness and low maintenance for online water quality monitoring; utilizing the characteristics of the hydrocyclone to reduce the consumption of other kinetic energy, with only the energy consumption of the water pump, thus achieving environmental protection and energy saving;

[0033] The tangential water inlet 1-1 and the tangential cleaning port 1-2 adopt an analog involute inlet design to ensure a high energy conversion rate when the pressure energy is converted into rotational energy.

[0034] In short, the utility model allows raw water to pass through the water inlet valve and adjust the pressure relief valve to allow the raw water to enter the pressure chamber module at a specific water pressure. The raw water forms a vortex in the pressure chamber module to drive the impeller to rotate and flush the filter plate. At the same time, the raw water passes through the filter plate and prepares a water sample suitable for the water quality equipment from the water outlet valve for sampling and analysis by the water quality equipment. In this way, the water sample filtration device can be self-cleaned, anti-clogging, and continuously prepare samples for the water quality equipment, thereby achieving high timeliness and low maintenance for online water quality monitoring. The characteristics of hydraulic vortex are used to reduce the consumption of other kinetic energy, and only the energy consumption of the water pump is consumed, thereby achieving environmental protection and energy saving.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
