[0044] Combined with Figure 1 - Figure 2 As shown, the filtering mechanism 4 includes a filtering tank 401. Two partition plates are provided in the filtering tank 401. The two partition plates are divided into a first partition plate 402 and a second partition plate 403. The first partition plate 402 and the second partition plate 403 are arranged opposite to each other and jointly form a connection channel 404.

[0045] The first partition plate 402 is connected to the bottom of the filtration tank 401 and forms a first chamber with the filtration tank 401.

[0047] The filtration assemblies 5 are respectively installed on the first mounting plate 405 and the second mounting plate 408 and are respectively arranged in the first filtration chamber 406 and the second filtration chamber 409. During the flow of well water, it will be filtered once by the filtration assembly 5 in the first filtration chamber 406. After that, it enters the second filtration chamber 409 through the first communication chamber 407 and the connection channel 404 and is filtered twice by the filtration assembly 5. Finally, it is output from the second communication chamber 410. Thus, through the above structure and the filtration assembly 5, multiple filtrations of well water are realized, ensuring the filtration quality of well water.

[0048] Combined with Figure 1 and Figure 2 As shown, the filtration assembly 5 includes a mounting cylinder 501.

One end of the mounting cylinder 501 away from the first mounting plate 405 and the second mounting plate 408 is fixedly connected with a filtration cylinder 502. A plurality of layers of filter meshes are provided on the filtration cylinder 502. By providing the mounting cylinder 501, it is convenient to install the filtration assembly 5 on the first mounting plate 405 and the second mounting plate 408. By providing the filtration cylinder 502 with a plurality of layers of filter meshes, the filtration of well water is realized through the filtration cylinder 502 and the filter meshes.

[0049] Combined with Figure 1 and Figure 2 As shown, the filtration and backwashing assembly 13 includes a first pressure detector 1301 and a second pressure detector 1302. The first pressure detector 1301 is arranged at the water inlet end of the filtration mechanism 4, and the second pressure detector 1302 is arranged at the water outlet end of the filtration mechanism 4.

In addition, the controller is also connected to the water inlet electric valve 3, the water outlet electric valve 6, the backwashing electric valve 1304, the sewage discharge electric valve 1307, and each delivery pump;

[0050] After the controller receives the pressure signals transmitted by the first pressure detector 1301 and the second pressure detector 1302, it calculates the pressure difference before and after the filtering mechanism 4. When the pressure difference is greater than the set value, the controller controls the inlet water electric valve 3 and the outlet water electric valve 6 to close, and the backwash electric valve 1304 to open, so as to realize the backwashing of the filtering mechanism 4.

[0051] The controller is connected to the backwash electric valve 1304. The backwash electric valve 1304 is installed on the backwash pipeline 1305.

The wastewater after backwashing is discharged through the sewage discharge electric valve 1307.

[0052] Combined with Figure 1 and Figure 2 As shown, the end of the backwash pipeline 1305 far away from the purified water pressure tank 8 is of a Y-shaped structure and includes two connecting pipes. The two connecting pipes are respectively connected to the first communication chamber 407 and the second communication chamber 410, so as to realize the backwashing of the filtering components 5 in the first chamber and the second chamber. At the same time, through the control of the backwash electric valve 1304, the backwashing action of the first chamber or the second chamber can be carried out separately.

A residual chlorine detector 702 is arranged in the detection flow cell 701. The residual chlorine detector 702 is signal-connected to the disinfectant dosing component 14. Through the residual chlorine detector 702, the residual chlorine content in the water can be detected, and the detection result of the residual chlorine content is transmitted to the disinfectant dosing component 14 to control the dosing amount of the disinfectant dosing component 14.

[0054] Combined with Figure 1As shown, the disinfectant dosing assembly 14 includes a disinfectant storage tank 1401. A dosing pipeline 1402 is connected to the disinfectant storage tank 1401.

A dosing pump 1403 and a check valve 1404 are installed on the dosing pipeline 1402. The dosing pump 1403 is signal-connected to the residual chlorine detector 702. Through the dosing pump 1403, the check valve 1404 and the dosing pipeline 1402, disinfectant can be added to the water inlet end of the filtration mechanism 4 to kill microorganisms such as viruses and bacteria in the water. Since the dosing pump 1403 is signal-connected to the residual chlorine detector 702, when the residual chlorine detector 702 detects that the residual chlorine content in the water after filtration by the filtration mechanism 4 exceeds the set value, the dosing pump 1403 will reduce the dosing amount.

[0055] Combined with Figure 1 As shown, an overflow plate 201 is provided in the water storage tank 2 along the vertical direction. The overflow plate 201 divides the water storage tank 2 into a water inlet sedimentation chamber 202 and an overflow water outlet chamber 203;

[0057] The overflow water outlet chamber 203 is connected to the water inlet end of the filtration mechanism 4. Through the overflow plate 201, the water inlet sedimentation chamber 202 and the overflow water outlet chamber 203, the well water can be preliminarily sedimented, so that the large particle impurities contained in the well water settle in the water inlet sedimentation chamber 202 and are regularly discharged through the sediment discharge pipeline 204, improving the filtration efficiency of the subsequent filtration mechanism 4.

[0058] For the convenience of understanding, the working process of this embodiment is given as follows:

[0059] Combined with Figure 1 - Figure 2As shown in the figure, first, the well water lift pump 1 transports the well water in the deep well to the inlet sedimentation chamber 202 of the water storage tank 2, where it sedimentates, and then is transported to the overflow outlet chamber 203 through the overflow plate 201. After that, the water in the overflow outlet chamber 203 is transported to the first filtration chamber 406 of the filtration mechanism 4 through the transport pump and the inlet electric valve 3. At the same time, the disinfectant in the disinfectant storage tank 1401 is transported to the inlet end of the filtration mechanism 4 through the chemical addition pipeline 1402, the chemical addition pump 1403 and the one-way valve 1404. It is first filtered by the filtration component 5 in the first filtration chamber 406, and then enters the second filtration chamber 409 through the first communication chamber 407 and the connection channel 404. After being secondarily filtered by the filtration component 5, it enters the second communication chamber 410. Then, it is transported to the detection flow cell 701 through the transport pump and the outlet electric valve 6, and the residual chlorine content in the water is detected by the residual chlorine detector 702. When the detected information is transmitted to the chemical addition pump 1403, the chemical addition pump 1403 controls the chemical addition amount to keep the residual chlorine content within the set range. After that, the filtered water is transported to the clean water pressure tank 8 through the transport pump. The water in the clean water pressure tank 8 is connected to the user water carrier 11 or the tap water network 12 through the flow detector 9 and the external supply electric valve 10, so as to provide water for the user water carrier 11 or the tap water network 12.
