The filter drum 16 has a water outlet 161 formed on the outer peripheral surface and communicating with the filtrate space 15.

The liquid to be filtered is generally pumped by the water pump and enters the liquid containing space 11 through the water inlet 121. The liquid to be filtered in the liquid containing space 11 is affected by the gravity and flows downward from the opening 13 to flow. During the process, it is filtered through the screen 17, and is collected into the filtrate space 15, and finally sent out by the water outlet 161 for use. Although the filter 1 can simply filter the liquid by gravity, the filtered dirt and impurities can be stuck in the pores of the sieve 17, causing the pores to clog and the water flow not easily pass, thereby causing the filtration speed to be lowered or even stagnated. The situation. Therefore, the maintenance personnel often have to shut down the filter 1 to shut down or clean the filter 17, which not only requires labor and time, but also reduces the filtration efficiency.

The filter tube is disposed in the inner space of the filter drum, and the bottom portion extends through the bottom opening. The filter tube divides the internal space into a filtering area, and a to-be-filtered area outside the filtering area and communicating with the water inlet and the water outlet. And the filter tube has a water outlet connected to the filter area and used for the filtered liquid to flow out. The turbine is disposed in the area to be filtered of the inner space and is rotatable relative to the filter tube by the flowing liquid to be filtered. The brushing member is coupled to the turbine and disposed in the area to be filtered around the filter tube. The brushing member can be rotated by the turbine to remove dirt on the filter tube.

The utility model has the following effects: the rotating of the turbine can drive the brushing member to rotate and brush the dirt outside the filter tube, so the novel can be self-cleaning at the same time in the filtering process without the need for water shut down and frequent replacement. Filter consumables for easy maintenance and high filtration efficiency. Moreover, the turbine can be pushed by the flowing liquid to be filtered without additional use of electric energy, saving energy and being environmentally friendly.

Referring to FIG. 3, FIG. 4 and FIG. 5, an embodiment of the present invention is provided with an additional power self-cleaning filter 2, which comprises a filter drum 3, a filter tube 4 disposed in the filter drum 3, and a filter barrel. A turbine 5 located directly above the filter tube 4, a brushing member 6 connecting the turbine 5 and surrounding the filter tube 4, and a control valve 7 disposed on the filter drum 3.

The filter drum 3 includes a barrel 31 defining an interior space 310. The barrel body 31 has a water inlet 311 formed at the top and communicating with the inner space 310, a bottom opening 312 formed at the bottom and communicating with the inner space 310, and a bottom opening 312 formed at the bottom of the outer peripheral surface and communicating with the inner space 310 Drain port 313.

The filter tube 4 is disposed upright in the inner space 310 of the filter can 3, and the bottom portion protrudes downward from the bottom opening 312 of the filter can 3. The filter tube 4 divides the internal space 310 into a filtering area 314, and a to-be-filtered area 315 located outside the filtering area 314 and communicating with the water inlet 311 and the water outlet 313. The filter tube 4 has an aperture 41 for water permeation on the surface thereof and a water outlet 42 connected to the filter area 314.

The turbine 5 is rotatably covered with respect to the filter tube 4 at the top end of the filter tube 4, and the opening of the filter tube 4 is closed, so that the filter region 314 can only communicate through the aperture 41 of the surface of the filter tube 4. The area to be filtered 315. In the present embodiment, the filter tube 4 has a sleeve 43 for the brushing member 6. The turbine 5 has a gear meshing engagement with the sleeve 43 (not shown) to drive the sleeve 43 to rotate. Turbine blades 51. When the turbine blade 51 is driven, the sleeve 43 can be rotated in the reverse direction. The brushing member 6 is coupled to the turbine 5 to be rotated and attached to the outer surface of the filter tube 4. It should be specially noted that the direction of rotation indicated in FIG. 5 is for reference only, and actually can be reversely rotated according to different needs. The control valve 7 is disposed on the drain port 313 and can be manually opened and closed to open and close the drain port 313 so that the liquid of the region to be filtered 315 flows out of the drain port 313.

Referring to FIG. 4, FIG. 5 and FIG. 6, in the operation of the embodiment, the collected liquid to be filtered is pumped to the water inlet 311 through a water pump (not shown), so that the liquid to be filtered flows into the area to be filtered. In 315, in the foregoing process, the kinetic energy of the liquid to be filtered flows to drive the turbine 5 to rotate. The liquid to be filtered in the area to be filtered 315 passes through the pores 41 on the surface of the filter tube 4 by pressure, and is filtered by the filter tube 4 to enter the filtering area 314, thereby achieving the filtering effect, and finally passing the filter. The filtered liquid of the tube 4 is outputted outward from the water outlet 42. In the foregoing filtering process, the turbine 5 is rotated by the liquid to be filtered to drive the brushing member 6 to rotate relative to the filter tube 4, so that the brushing member 6 and the filter tube 4 are rubbed, thereby achieving brushing. Decontamination function of dirt. The brushed dirt will settle in the area to be filtered 315 due to its own weight, and the control valve 7 can be manually opened to open the drain port 313 to discharge the liquid containing the dirt from the drain port 313. Of course, the control valve 7 can also be periodically opened through the timing operation module 71, so that the liquid with the dirt is automatically discharged at intervals. Since the turbine 5 can be rotated by the liquid to be filtered, energy can be saved without additional power supply. The brushing member 6 is rotated to remove dirt on the filter tube 4, and the filter tube 4 is still It can continue to filter the liquid, so it can run continuously without stopping the water during the filtration process, effectively improving the filtration efficiency and the utilization rate.

In summary, the brushing member 6 can drive the brushing member 6 to rotate, and the brushing member 6 can be rotated relative to the filter tube 4 during the filtering process to remove dirt on the outside of the filter tube 4, so that no shutdown is required. The water can be cleaned automatically, which effectively improves the filtration efficiency and convenience, so it can achieve the purpose of the new model. Moreover, the rotation of the turbine 5 is driven by the flow of the liquid to be filtered, and energy can be saved without additional power connection.
