Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a domestic sewage permeation filtering device. Background Art

[0002] In daily life, people usually discharge domestic sewage directly, which will cause a waste of water resources. Solid waste discharged into the sewer can easily cause sewer blockage. Most of the water used in our daily sinks and when washing vegetables can be recycled, such as mopping the floor, flushing the toilet, etc., but now people generally do not recycle it, and recycling generally only uses the water in the basin when washing vegetables. Most of the water will still be wasted. Therefore, domestic sewage treatment equipment becomes particularly important.

[0003] Existing sewage treatment devices generally consist of a single or multiple filter plates. After filtering domestic sewage for a long time, the filter plates installed on the device are very likely to retain filtered domestic garbage and a large amount of bacteria. Although some existing filtration devices can disassemble and clean the filter plates, the process is not only time-consuming and labor-intensive, but the bacterial residues may not be completely removed.

[0004] For example, an existing Chinese patent (publication number: CN218392410U) discloses a domestic sewage filtering device, including a filtering device body, and a water outlet pipe fixedly connected to the left outer surface of the filtering device body, and a water inlet pipe fixedly connected to the front outer surface of the filtering device body, a rectangular mounting block movably connected to the left inner surface of the filtering device body, a fixed handle fixedly connected to the left outer surface of the rectangular mounting block, and a bottom mounting frame fixedly connected to the right outer surface of the rectangular mounting block.

[0005] However, the above device still has certain disadvantages. For example, although the filter net of the above design can be disassembled for cleaning, the disassembly process is relatively troublesome, and the whole process requires manual operation to clean and dry the filter net, which is not only time-consuming and laborious, but also generates unnecessary water consumption. Although the best efforts have been made, the cleaning effect is still not ideal. Drying can only remove some bacteria, and the remaining bacteria will still remain inside the device.

[0006] Therefore, we designed a domestic sewage infiltration filtration device to solve the above problems. Utility Model Content

[0024] The embodiments of the present utility model are described in detail below.

[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Embodiment 1

[0027] Depend on Figure 1-4A domestic sewage infiltration filtering device is provided, comprising a filter box 1, four brackets 17 are installed at the bottom of the filter box 1, a square tube 3 is connected to the left side of the filter box 1, a water inlet pipe 2 is connected to the other side of the square tube 3, a pullable pull block 11 is installed at the bottom of the square tube 3, a square filter port 8 is provided on the right side of the square tube 3, a mounting groove and a cavity are provided inside the filter box 1, a heating resistor wire 9 is installed in the mounting groove, a plurality of mounting blocks 5 are installed in the cavity of the filter box 1, different devices are fixed in the mounting blocks 5 at different heights, a second filter plate 7 is installed on the upper surface of the bottom mounting block 5, and a first filter plate 7 is installed on the upper surface of the mounting block 5 in the middle position. A filter plate 6, a first filter plate 6, a second filter plate 7, and a square filter port 8 are all provided with through holes on their surfaces, wherein the through hole provided in the square filter port 8 is larger than the hole provided in the first filter plate 6, and the through hole provided in the first filter plate 6 is larger than the through hole provided in the second filter plate 7. An outlet pipe 4 is installed on the bottom surface of the filter box 1, and the other side of the outlet pipe 4 is connected to a transition water tank 12, and the right side of the transition water tank 12 is connected to an open water tank 15 through a circular pipe, and a drain port 16 is provided at the bottom of the front side of the open water tank 15, and a sealing cover is installed at the front end of the drain port 16, and a water pump 13 is installed at the upper end of the transition water tank 12, and a return pipe 14 is installed at the top end of the water pump 13, and the other side of the return pipe 14 is connected to the filter box 1.

[0028] In the specific implementation, the top of the water inlet pipe 2 is first aligned with the wastewater outlet. After the water inlet pipe 2 is connected to the wastewater, it will first enter the square tube 3, and the square filter port 8 opened on the right side of the square tube 3 will initially intercept the larger garbage and store it in the square tube 3. When the volume of the square tube 3 is about to be full, the pull block 11 installed at the bottom can be pulled to make the large volume of garbage in the square tube 3 fall down, thereby making the square tube 3 unobstructed, and then enter the cavity of the filter box 1. The wastewater that has been initially filtered will first flow through the first filter plate 6, and the through holes opened on the upper surface of the first filter plate 6 are smaller than the through holes opened on the surface of the square filter port 8, so that secondary filtration can be performed. After the secondary filtration, the wastewater will flow through the second filter plate 7, and the through holes opened on the upper surface of the second filter plate 7 are smaller than the through holes of the first filter plate 6 and the square filter port 8, so that the wastewater will be filtered three times, and the wastewater can be reused after the three filtrations.

[0029] After being filtered three times, the waste water will flow into the transition water tank 12 through the outlet pipe 4. When the first filter plate 6 and the second filter plate 7 do not need to be cleaned, the water will not stay in the transition water tank 12, and will flow into the open water tank 15 through the circular pipe. The upper surface of the open water tank 15 is sealed. When the water in the open water tank 15 is needed to wash vegetables, mop the floor, or water the plants, water can be directly taken from the upper end of the open water tank 15. When water is not needed in a short period of time, the sealing cover at the front end of the drain port 16 can be opened to allow the water in the open water tank 15 to flow out through the drain port 16.

[0030] When the first filter plate 6 and the second filter plate 7 need to be cleaned, the water pump 13 can be started after the water has been filtered three times. After starting the water pump 13, the water flowing into the transition water tank 12 will be sucked into the return pipe 14 by the suction force of the water pump 13, and finally discharged into the cavity opened in the filter box 1 through the connection between the return pipe 14 and the filter box 1, so as to rinse the first filter plate 6 and the second filter plate 7 in the cavity of the filter box 1. While rinsing, pull the two pull rods 10, because the positions of the two pull rods 10 correspond to the first filter plate 6 and the second filter plate 7 respectively, so that after pulling the pull rods 10, there will be chutes on the side positions of the first filter plate 6 and the second filter plate 7, and the garbage remaining on the upper surfaces of the first filter plate 6 and the second filter plate 7 can be discharged through the chute by relying on the force of the water discharged from the return pipe 14, thereby achieving the purpose of simple cleaning.

[0031] Embodiment 2

[0032] Based on Example 1, refer to Figure 1-4 A domestic sewage infiltration filtering device comprises a filter box 1, wherein a mounting groove and a cavity are provided inside the filter box 1, wherein a heating resistance wire 9 is installed in the mounting groove, and a plurality of heating resistance wires 9 are installed in the mounting groove provided inside the filter box 1, an outlet pipe 4 is installed on the bottom surface of the filter box 1, and the other side of the outlet pipe 4 is connected to a transition water tank 12, a water pump 13 is installed at the upper end of the transition water tank 12, a return pipe 14 is installed at the top end of the water pump 13, and the other side of the return pipe 14 is connected to the filter box 1.

[0033] In specific implementation, when the device has been used for a long time and bacteria have remained in the cavity opened inside the filter box 1, the interior can be flushed first to prevent too much garbage from remaining inside, and then the heating resistor wire 9 can be energized. After the heating resistor wire 9 is energized, high temperature will be generated, and then the high temperature will be transferred to the cavity of the filter box 1 through the partition, thereby achieving a sterilization effect through the high temperature, greatly reducing the residual bacteria rate in the device.

[0034] Working principle:

[0035] When a quick cleaning device is needed:

[0036] When the water has completed three filtrations, the water pump 13 is started. After the water pump 13 is started, the water flowing into the transition water tank 12 will be sucked into the return pipe 14 by the suction force of the water pump 13, and finally discharged into the cavity opened in the filter box 1 through the connection between the return pipe 14 and the filter box 1, so as to rinse the first filter plate 6 and the second filter plate 7 in the cavity of the filter box 1. While flushing, the two pull rods 10 are pulled, because the positions of the two pull rods 10 correspond to the first filter plate 6 and the second filter plate 7 respectively, so that after pulling the pull rods 10, chutes will appear on the side positions of the first filter plate 6 and the second filter plate 7, and the garbage remaining on the upper surfaces of the first filter plate 6 and the second filter plate 7 can be discharged through the chutes by relying on the force of the water discharged from the return pipe 14, thereby achieving the purpose of simple cleaning.

[0037] When thorough sterilization is required:

[0038] First, the interior is flushed to prevent too much garbage from remaining inside, and then the heating resistor 9 is energized. After the heating resistor 9 is energized, high temperature will be generated, and then the high temperature will be transferred to the cavity of the filter box 1 through the partition, thereby achieving a sterilization effect through the high temperature, greatly reducing the residual bacteria rate in the device.
