Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 4 As shown, the present invention provides a filter element for fine filtration, comprising a connecting housing 1, wherein a filter screen 2 and a filter screen 3 are disposed inside the connecting housing 1, a connecting cover 4 is disposed on the top of the filter screen 2 and the filter screen 3, an inlet pipe 5 and an outlet pipe 6 are connected inside the connecting cover 4, the inlet pipe 5 is connected to the connecting housing 1, and the outlet pipe 6 is connected to the inside of the filter screen 3, a connecting cover 7 is disposed at the bottom of the connecting housing 1, a rotary motor 8 is fixedly disposed at the bottom of the connecting cover 7, the output end of the rotary motor 8 extends through the inside of the connecting housing 1, a rotating cylinder 9 is fixedly connected to the output end of the rotary motor 8, the rotating cylinder 9 is fitted with the connecting housing 1, and a plurality of cleaning brushes 10 are fixedly connected inside the rotating cylinder 9, the cleaning brushes 10 being fitted with the filter screen 2.
[0021] refer to Figure 1 The interior of the connecting cover 2 7 is connected to a drain pipe 11, and a solenoid valve 12 is installed inside the drain pipe 11.
[0022] As a technical optimization of this utility model, by setting up a drain pipe 11, when the filter screen 2 is being cleaned, the outlet pipe 6 is closed, allowing water to enter the connecting housing 1 from the inlet pipe 5. Combined with the cleaning brush 10, the flushing effect can be achieved, improving the cleaning effect of this device. The wastewater after cleaning can be discharged by opening the drain pipe 11 through the solenoid valve 12, without the need for manual operation, making it easy to use.
[0023] refer to Figure 3 Both the first connecting cover 4 and the second connecting cover 7 are provided with threads 13 inside, and both the first connecting cover 4 and the second connecting cover 7 are movably connected to the connecting housing 1 through the threads 13.
[0024] As a technical optimization of this utility model, by setting the thread 13, the connecting cover 4 and the connecting cover 7 can be unscrewed by the personnel through the thread 13, so that the filter screen 2 and the filter screen 3 can be inspected and maintained, which is convenient for use.
[0025] refer to Figure 2 The interior of filter screen 12 is fitted with a POM skeleton 14, and the interior of the POM skeleton 14 is fitted with filter screen 2 3.
[0026] As a technical optimization of this utility model, by setting a POM skeleton 14, the interior of which is filled with scale-inhibiting filter material, scale can be prevented from forming on the filter screen 2 due to prolonged lack of cleaning, thus reducing the impact of dirt on water quality.
[0027] refer to Figure 4 Both filter screen 12 and filter screen 23 have a corrosion-resistant layer 15 on their surfaces.
[0028] As a technical optimization of this utility model, by setting a corrosion-resistant layer 15, the filter screen 12 and the filter screen 23 can be prevented from being corroded during filtration, thereby increasing the service life of the filter screen 12 and the filter screen 23.
[0029] refer to Figure 1 The filter screens 1 and 2 have a mesh size of 325, and the inlet pipe 5 and outlet pipe 6 are equipped with a POM isolation layer 16.
[0030] As a technical optimization of this utility model, by setting the mesh size to 325, the filter mesh density of filter screen 1 2 and filter screen 2 3 is less than 325 mesh, which is prone to clogging, and greater than 325 mesh, which is prone to leakage of filtered impurities. At this time, 325 mesh can accurately intercept impurities in the water, reducing the clogging and leakage of filter screen 1 2 and filter screen 2 3. In addition, the POM isolation layer 16 can indirectly separate the water source from the inlet pipe 5 and the outlet pipe 6, reducing the possibility of water source pollution.
[0031] The working principle and usage process of this utility model: In daily use, the inlet pipe 5 and outlet pipe 6 are connected to the pipeline. The inlet pipe 5 and outlet pipe 6 are made of brass. Brass is lightweight, has good thermal conductivity, good compressive strength, high resistance to high and low temperatures, and advantages such as corrosion resistance, antibacterial properties, and stable performance. Therefore, it can increase the service life of the inlet pipe 5 and outlet pipe 6. Water is then introduced into the connecting housing 1 through the inlet pipe 5. The outlet pipe 6 creates negative pressure inside the filter screen 3, causing the water to be filtered through the filter screens 2 and 3. The filter screens 2 and 3 can be made of 316L stainless steel, which has good air permeability, uniform and stable precision, and is not easily filtered. With advantages such as good leakage prevention, regeneration performance, and fast regeneration speed, it can improve the service life of filter screen 1 (2) and filter screen 2 (3), almost achieving the effect of never needing to replace the filter element for life. Filter screen 1 (2) will perform the initial filtration of the water source, and the impurities on the surface of filter screen 1 (2) will be cleaned by using an external power supply to power the rotary motor 8. The rotary motor 8 will drive the rotating drum 9 to rotate inside the connecting housing 1 through the output end, thereby causing the cleaning brush 10 to rotate on the surface of filter screen 1 (2), thus washing away the impurities on the surface of filter screen 1 (2), which can complete the cleaning effect of filter screen 1 (2), reduce the clogging of filter screen 1 (2), and clean filter screen 1 (2) without the need for personnel to disassemble and assemble it, reducing manpower and improving the cleaning efficiency of filter screen 1 (2).
