Description

Technical Field

[0001] This utility model belongs to the field of water resource protection technology, specifically a water resource protection and purification device. Background Technology

[0002] When reusing water sources such as domestic sewage, initial rainwater, and factory wastewater, purification treatment is generally required. Water purification methods include physical and chemical methods. Common physical methods include using filter media with various pore sizes to remove impurities from the water through adsorption or blocking. Among adsorption methods, activated carbon particles are particularly important. Blocking methods involve passing water through a filter screen to prevent larger impurities from passing through, thereby obtaining relatively clean water.

[0003] A search revealed a water resource protection and purification device disclosed in announcement number CN214936536U. Its main features include: a base plate; multiple support columns are fixedly connected to one end of the top surface of the base plate; a water-holding cylinder is fixedly connected to the top surface of the multiple support columns; two water outlet pipes are connected to the bottom surface of the water-holding cylinder; a water source filtration mechanism is connected to the bottom of the two water source filtration mechanisms; a U-shaped pipe is connected to the bottom of the U-shaped pipe; an L-shaped pipe is connected to the bottom of the U-shaped pipe; and a water source adsorption box is connected to the end of the L-shaped pipe facing away from the U-shaped pipe.

[0004] In practical use, the applicant has found that with the existing water resource protection and purification devices, the purified water first enters the water tank and is filtered by the filter screen inside the tank. However, in actual use, as filtration continues, impurities accumulate on the filter screen. If personnel do not clean it in time, the water permeability becomes less than the water inflow, leading to overflow of the water tank. To solve the above-mentioned problems, a water resource protection and purification device is proposed.

[0005] To address the aforementioned problems, a water resource protection and purification device is proposed. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following will combine Figures 1-3 A detailed description of a water resource protection and purification device according to an embodiment of this utility model is provided.

[0021] Example:

[0022] This utility model provides a water resource protection and purification device, which is referenced in the following embodiment. Figures 1 to 3 As shown, the system includes a housing 1. A water inlet pipe 2 is fixedly installed on the upper part of the housing 1. Branch pipes 3 and 4 are installed on the water inlet pipe 2. A grating plate 5 is fixedly installed inside the housing 1. A partition plate 6 is fixedly installed on the top surface of the grating plate 5. The partition plate 6 and the grating plate 5 divide the upper part of the housing 1 into a main filter chamber 7 and a backup filter chamber 8. A filter screen 9 is installed on the grating plate 5 in the main filter chamber 7, and a filter screen 10 is installed on the grating plate 5 in the backup filter chamber 8. An electric control valve 11 is installed on branch pipe 3, and an electric control valve 12 is installed on branch pipe 4. A level sensor 13 is installed on the upper part of the partition plate 6 on one side of the main filter chamber 7. A control cabinet 14 is installed on the outer wall of the housing 1. A PLC controller 15 is installed inside the control cabinet 14. The electric control valves 11 and 12, and the level sensor 13 are electrically connected to the PLC controller 15. The enclosure 1 is electrically connected to the PLC controller 15. In this structure, the inlet pipe 2 sends water into the branch pipe 3, which then enters the main filter chamber 7. The water is then filtered through the filter screen 9. When the filter screen 9 becomes clogged, the water level in the main filter screen 8 continuously increases. When the water level reaches the level sensor 13, the PLC controller 15 receives a signal from the level sensor 13. It then opens the solenoid valve 12 and simultaneously closes the solenoid valve 11, allowing water to enter the backup filter chamber 8. The filter screen 10 is then used temporarily to prevent overflow. Simultaneously, the PLC controller 15 activates the alarm 16, reminding personnel to clean the main filter chamber 7 promptly. The temporary filtration by the filter screen 10 provides sufficient time for personnel to clean the filter screen 9.

[0023] The entire structure prevents water from overflowing from the housing 1, while the alarm device can promptly remind personnel to maintain the filter screen. Filter screen 2 10 is used as a temporary filter, thus giving personnel enough time to clean filter screen 1 9.

[0024] It should be noted that the PLC controller 15, liquid level sensor 13, alarm 16, solenoid valve 11 and solenoid valve 2 are all devices well known in the art. The preferred model of PLC controller 15 is S7-1200, the preferred model of liquid level sensor 13 is GEMS ELS-950, the preferred model of alarm 16 is GEMS ELS-950, and the preferred models of solenoid valve 11 and solenoid valve 2 are SMC VXD262NG.

[0025] refer to Figures 1 to 3 As shown, the outlet of branch pipe 3 is located in the main filter chamber 7, and the outlet of branch pipe 4 is located in the spare filter chamber 8.

[0026] refer to Figures 1 to 3 As shown, a support leg 17 is fixedly installed on the lower part of the box 1. This structure uses the support leg 17 to support the box 1.

[0027] refer to Figures 1 to 3 As shown, a drain pipe 18 is fixedly connected to the lower part of the housing 1. In this structure, the drain pipe 18 discharges the filtered water into the next filtration device.

[0028] The implementation principle of a water resource protection and purification device according to an embodiment of this application is as follows: Water is sent into branch pipe 3 through inlet pipe 2, and then the water enters the main filter chamber 7. The water is then filtered through filter screen 9. When filter screen 9 becomes clogged, the water level in the main filter screen 8 continues to increase. When it reaches the level sensor 13, the PLC controller 15 receives a signal from the level sensor 13. Then, it first opens solenoid valve 12 and then simultaneously closes solenoid valve 11, allowing water to enter the backup filter chamber 8. Filter screen 10 is then used temporarily to prevent overflow due to blockage. At the same time, the PLC controller 15 will activate alarm 16 to remind personnel to clean the main filter chamber 7 in time. The temporary filtration by filter screen 10 provides sufficient time for personnel to clean filter screen 9. After filter screen 9 is cleaned, personnel manually reset solenoid valve 11 and close solenoid valve 12, allowing water to re-enter the main filter chamber 7 for filtration. At this time, personnel clean filter screen 10 in the backup filter chamber 8, thus completing the cleaning work.

[0029] It should be noted that the specific control devices and control programs of the PLC involved in the above embodiments are technologies well known to those skilled in the art, and this application does not improve the specific control devices and control programs, so they will not be described in detail here.
