Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a novel multi-media filter which is easy to clean. Background Art

[0002] A multi-media filter is a type of water treatment equipment that uses two or more different filter media to remove suspended solids, microorganisms, organic matter, and other impurities from water. This type of filter can effectively improve water quality and is widely used in drinking water treatment, industrial water treatment, wastewater treatment, swimming pool water treatment, and other fields.

[0003] When the multi-media filter is working, the sewage to be filtered is usually added into the interior of the multi-media filter, and then the suspended particles and debris in the sewage are filtered through the filter layer. The filtered water flows out through the water filter cap and finally accumulates at the bottom of the multi-media filter. Then the drain valve is opened and the purified water flows out through the drain pipe. As the filtration proceeds, impurities in the filter layer gradually accumulate, resulting in a decrease in the filtration effect. At this time, the multi-media filter needs to be backwashed, that is, the flushing water is used to reversely flush from the bottom of the filter layer to flush away the deposited impurities, and finally discharged through the sewage pipe to restore the filtration capacity of the filter layer.

[0004] When using the existing multi-media filter, due to the certain viscosity of some impurities, after a long period of extraction, the dirt will stick to the inner wall of the sewage pipe, and eventually the sewage pipe will be blocked. At this time, it is necessary to manually dredge it through external equipment, but the operation is more troublesome and the dredging time is relatively long, so the time spent on cleaning the multi-media filter is also relatively long. For this reason, we propose a new multi-media filter that is easy to clean. Utility Model Content

The driving gear 77 on the right side is meshed with the teeth provided at the lower end of the double-sided rack plate 79. The new multi-media filter that is easy to clean can drive the reciprocating motion of the knocking hammer 75 during the cleaning and drainage process, so that the knocking hammer 75 can knock on the sewage pipe 72, thereby shaking off the debris adhered to the inner wall of the sewage pipe 72, and no manual dredging work is required, further shortening the time spent on cleaning and drainage, and solving the problem of cleaning efficiency affected by the blockage of the sewage pipe 72.

[0025] Among them: it also includes a control switch 2, which is located outside the tank body 1. The input end of the control switch 2 is electrically connected to the external power supply and can regulate the electrical components inside the device.

[0026] Among them: a spring 15 is provided between the rear end of the double-sided rack plate 79 and the rear wall of the protective cover 71. The spring 15 is sleeved on the rear side of the hexagonal sliding column 73 on the right side.

The half gear 9 is installed in cooperation with the teeth provided on the upper end of the double-sided rack plate 79. The input end of the motor 8 is electrically connected to the output end of the control switch 2. During the cleaning and sewage discharge process, the motor 8 starts to run through the regulation of the control switch 2, and the output end of the motor 8 drives the half gear 9 to rotate.

The outer surface of the water filter cap 11 is in contact with the lower surface of the activated carbon filter layer 14. The sewage passes through the perlite filter layer 12, the fine sand filter layer 13 and the activated carbon filter layer 14 to filter the suspended particles and debris in the sewage, while the clean water flows out through the water filter cap 11 and finally accumulates at the bottom of the tank body 1.

[0029] Among them: a water inlet pipe 3 is provided in the water inlet opened on the front side of the outer arc surface of the tank body 1, and a water inlet valve is connected in series on the front side of the water inlet pipe 3. A connecting pipe 5 is provided in the middle of the top wall of the tank body 1. The front end of the connecting pipe 5 is connected to the rear end of the water inlet pipe 3, and a water diversion pipe 6 is provided on the lower side of the outer arc surface of the connecting pipe 5. When the water inlet valve is opened, the sewage to be filtered flows into the interior of the connecting pipe 5 through the water inlet pipe 3, and then the sewage is diverted through the water diversion pipe 6 so that the sewage is evenly sprinkled on the upper end of the perlite filter layer 12.

[0030] The working principle of the new multi-media filter provided by the present invention, which is easy to clean, is as follows: before use, the water inlet pipe 3, the drainage pipe 4 and the sewage pipe 72 are connected to the external pipe. When the new multi-media filter, which is easy to clean, is working, the water inlet valve is opened, and the sewage to be filtered flows into the interior of the connecting pipe 5 through the water inlet pipe 3, and then the sewage is diverted through the water diversion pipe 6, so that the sewage is evenly sprinkled on the upper end of the perlite filter layer 12, and then the suspended particles and debris in the sewage are filtered through the perlite filter layer 12, the fine sand filter layer 13 and the activated carbon filter layer 14. The filtered water flows out through the water filter cap 11 and finally accumulates at the bottom of the tank body 1. Open the drain valve and the purified water will flow out through the drain pipe 4. When it is necessary to clean the new multi-media filter that is easy to clean, the flushing water enters the interior of the tank body 1 through the drain pipe 4, and then enters the interior of the perlite filter layer 12, the fine sand filter layer 13 and the activated carbon filter layer 14 through the water filter cap 11. The flushing water performs reverse flushing from the bottom of the activated carbon filter layer 14 to wash away the deposited impurities, thereby restoring the filtering capacity of the perlite filter layer 12, the fine sand filter layer 13 and the activated carbon filter layer 14. Then, open the sewage valve and the deposited impurities are discharged through the sewage pipe 72. During the cleaning and sewage discharge process, the motor 8 starts to operate by controlling the control switch 2. The output end of the motor 8 drives the half gear 9 to rotate. When the half gear 9 is meshed with the double-sided rack plate 79, the half gear 9 drives the double-sided rack plate 79 to move forward. The spring 15 extends, and the double-sided rack plate 79 drives the right driving gear 77 to rotate through the meshing connection during the movement. The right driving gear 77 drives the left driving gear 77 to rotate through the mounting rod 76. The left driving gear 77 drives the two rack plates 78 to move through the meshing connection. The rack plate 78 drives the knock hammer 75 to move through the sliding column 74. Finally, the knock hammer 75 contacts the outer arc surface of the sewage pipe 72. When the half gear 9 is meshed with the double-sided rack plate 79, the knock hammer 75 contacts the outer arc surface of the sewage pipe 72. When the surface rack plates 79 are separated, the tension generated by the contraction of the spring 15 drives the double-sided rack plates 79 to move and reset. During the movement, the double-sided rack plates 79 drive the right-side driving gear 77 to rotate and reset through the meshing connection. The right-side driving gear 77 drives the left-side driving gear 77 to rotate and reset through the mounting rod 76. The left-side driving gear 77 drives the two rack plates 78 to move and reset through the meshing connection. The rack plate 78 drives the knocking hammer 75 to move and reset through the sliding column 74. The knocking hammer 75 is used to knock on the sewage pipe 72, so as to shake off the debris adhering to the inner wall of the sewage pipe 72, thereby preventing the sewage pipe 72 from being blocked and affecting the cleaning efficiency.

[0031] It is worth noting that the motor 8 disclosed in the above embodiment can be made of ECMA-C20604RS, and the control switch 2 is provided with a control button corresponding to the motor 8 for controlling its switch.
