[0023] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0024] Embodiment 1

[0025] Reference Figures 1 to 3 As shown, a household sediment type sink provided in this embodiment includes a sink 10, a basin 20, a sediment suction pipe 30, a communicating vessel 50 and an external water seal groove 60. The sink 10 has a main tank body 11 and a sub-tank body 12. The main tank body 11 and the sub-tank body 12 are connected at the bottom. Figure 1As shown, the bottom of the main tank body 11 and the auxiliary tank body 12 are connected through a connecting channel 13, the bottom of the main tank body 11 is provided with a filter layer 40, the basin 20 is sealed and installed on the top of the sink 10, and the bottom of the basin 20 is connected to the main tank body 11 through a discharge pipe 21 with a water seal, so that the main tank body 11 and the auxiliary tank body 12 form a closed space; in this embodiment, the top of the main tank body 11 is open, the auxiliary tank body 12 is sealed, and only the bottom is connected to the main tank body 11. The basin 20 is sealed and installed at the upper opening position of the main tank body 11; the discharge pipe 21 is a U-shaped pipe, which can achieve water sealing after discharging the sewage 1, so as to prevent the sink 10 from being directly connected to the outside through the discharge pipe 21. In this way, the main tank body 11 and the auxiliary tank body 12 form a closed space.

[0026] The sediment suction pipe 30 and the communicating vessel 50 are both sealed and assembled on the water tank 10. The sediment suction pipe 30 is provided with a switch valve 31. The first port of the sediment suction pipe 30 is located in the main tank body 11 and above the filter layer 40, and the second port thereof is located outside the water tank 10. The sediment suction pipe 30 is used to suck sediment. The first port of the communicating vessel 50 is located in the auxiliary tank body 12, and the second port thereof is located outside the water tank 10 and extends into the external water seal groove 60 to achieve water seal, that is, there is a certain water level in the external water seal groove 60, and the second port of the communicating vessel 50 extends into the external water seal groove 60 and is lower than the water level, so as to prevent the water tank 10 from being directly connected to the outside through the communicating vessel 50.

[0027] The present embodiment also provides a household sewage treatment method, providing the household sediment-type sink described above; closing the switch valve 31 of the sediment suction pipe 30, and the sewage 1 generated by the household is discharged into the main tank body 11 of the sink 10 through the basin 2, and the sewage 1 is filtered through the filter layer 40, and the residue in the sewage 1 is blocked by the filter layer 40 and deposited on the surface of the filter layer 40 to obtain a sediment layer 2, and the filtered water 3 obtained by filtration flows into the auxiliary tank body; as the sewage 1 is continuously discharged from the basin 2, the pressure in the sink 10 increases, thereby driving the filtered water 3 in the sink 10 to be discharged outwardly through the connecting vessel 50 in a siphon manner; when the sediment needs to be treated, the switch valve 31 of the sediment suction pipe 30 is opened, and the sediment layer 2 is sucked out; that is, the second port of the sediment suction pipe 30 can be connected to the extraction equipment, thereby realizing the suction of the sediment layer 2.

[0028] The sewage treatment is carried out by using sedimentation filtration and siphon technology, which is carried out spontaneously during operation, that is, the sewage 1 is continuously discharged from the basin 2, and the pressure in the sink 10 increases, thereby driving the filtered water 3 in the sink 10 to be discharged outward through the connecting vessel 50 in a siphon manner, without incurring any operating cost.

[0029] The device (referring to the household sludge sink) is small and does not take up too much space. It can be installed in the space under the basin in a conventional kitchen. It is suitable for most places (especially for home use), and the siphon technology can ensure long-term normal operation without blockage, and basically does not require manual maintenance and subsequent clearing. The structure of the device is fixed, there are no consumables during operation, and it is spontaneous, so it does not require energy consumption, which is in line with the green, low-carbon and environmental protection concept.

[0030] Specifically, during the entire operation of the device, the water tank 10 remains completely sealed, so that the organic matter inside the water tank 10 does not undergo aerobic reaction to decompose small particles that can be dissolved in water, ensuring that most of the organic matter is filtered out. After the organic residue is deposited, the sediment layer 3 can be sucked out regularly, and the sucked out residue can be used for breeding fish, earthworms and other organisms after drying.

[0031] At the same time, the communicating vessel 50 can backwash the filter layer 40 in the main tank body 11 from the auxiliary tank body 12 through an external backwashing device (i.e., the second port of the communicating vessel 50 is externally connected to the backwashing device), thereby achieving the effects of clearing blockages, maintaining filtration efficiency, and extending the life of the device. The operation is simple, easy to implement, and has low time consumption and cost.

[0032] Specifically, the filter layer 40 is provided with multiple layers, three layers in this embodiment, and are stacked from bottom to top, namely, a first gravel layer 41 laid on the bottom layer, a second gravel layer 42 laid on the surface of the first gravel layer 41, and a third gravel layer 43 laid on the surface of the second gravel layer 42. The gravel particle size of the first gravel layer 41 is 20mm-50mm; the gravel particle size of the second gravel layer 42 is 4mm-8mm; the gravel particle size of the third gravel layer 43 is 0.01mm-1mm; that is, the particle size increases from bottom to top. The third gravel layer 43 on the top can effectively intercept fine particle residues and prevent the fine particle residues from filling the inside of the filter layer 40. The gravel layer with large particle size at the bottom can effectively prevent gravel particles from entering the auxiliary tank body 12, thereby ensuring the stability of the filter layer; further, the connecting passage 13 between the main tank body 11 and the auxiliary tank body 12 can be composed of a plurality of small holes, each of which has a smaller hole size than the gravel particle size of the first gravel layer 41. At the same time, the gravel layer is made of natural materials, which can be obtained by oneself and has low cost.

[0033] The above-mentioned setting of the filter layer 40 is one of the more preferred schemes in the present application. Of course, in other embodiments, the filter layer 40 can also be a single layer, two layers or more than three layers. The particle size of each layer of the filter layer 40 can be set according to actual conditions, and the type of each layer of the filter layer 40 can also be set according to actual conditions, such as using a ceramic filter layer, a sponge filter layer, etc.

[0034] Furthermore, in this embodiment, the first port of the sediment suction tube 30 is preferably slightly higher than the surface of the filter layer 40, preferably slightly higher than the surface of the filter layer 40 by about 1 cm. In this way, not only can the residue layer 3 be effectively sucked out, but the filter layer 40 can also be effectively prevented from being sucked out.

[0035] Furthermore, in this embodiment, a vertically upward partition 14 is provided at the bottom of the auxiliary tank body 12, so that the bottom of the auxiliary tank body 12 forms a first space 16 connected to the main tank body 11 and a second space 17 isolated from the main tank body 11, the first space 16 and the second space 17 are connected at the top, and the first port of the communicating vessel 50 is located in the second space 17; the filtered water (i.e., the filtered water 3) fills the first space 16 and overflows the second space 17. This process prevents small particles that are not completely filtered from entering the communicating vessel 50, thereby providing a guarantee for the smooth operation of the communicating vessel 50.

[0036] Further preferably, in the present embodiment, the communicating vessel 50 comprises a hard tube 51 and a hose 52, wherein the hard tube 51 forms a sealing match with the water tank 10, and the hose 52 is arranged in the hard tube 51 and forms a sealing match with the hard tube 51, so as to ensure that the water tank 10 is airtight inside and outside. The two ports of the hose 52 are respectively the first port and the second port of the communicating vessel 50. The assembly of the hard tube 51 is more convenient for sealing and fixing with the water tank 10, and the cooperation of the hose 52 is added, and the hose 52 can be adjusted at will within a certain range, and the practicality is better. Of course, in other embodiments, the communicating vessel 50 can also be a hard tube 51 alone, or a hose 52 alone, etc.

[0037] The external water seal groove 60 is a three-way pipe, having a lower pipe section 61 pointing vertically downward, an upper pipe section 62 pointing vertically upward, and a horizontal pipe section 63 extending horizontally. The end of the lower pipe section 61 is sealed to form a water storage cavity, and the second port of the communicating vessel 50 penetrates into the lower pipe section 61 through the upper pipe section 62, so that the second port of the communicating vessel 50 forms a water seal; the horizontal pipe section 63 is used for external piping; the filtered water 3 discharged from the communicating vessel 50 flows into the lower pipe section 61, and after the lower pipe section 61 overflows, it flows out from the horizontal pipe section 63 and is discharged.

[0038] The household sediment-type sink provided in this embodiment can re-purify sewage to a great extent and can maintain continuous operation for a long time without clogging.

[0039] Embodiment 2

[0040] The structure of a household sedimentation sink provided in this embodiment is substantially the same as that of the first embodiment, except that: Figure 4As shown, in this embodiment, a barrier layer 15 for filtering particulate matter is provided in the sub-tank body 12. The barrier layer 15 is a structure such as a sponge that can filter particulate matter. The first port of the communicating vessel 50 is located above the barrier layer 15. The particulate matter is filtered by the barrier layer 15 to prevent the particulate matter from entering the communicating vessel 50 and causing abnormalities such as blockage of the communicating vessel 50.

[0041] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
