Description

Technical Field

[0001] The present invention relates to the field of domestic sewage treatment, and specifically to an in-cabinet domestic sewage treatment system and method. Background Art

[0002] An in-cabinet domestic sewage treatment system is a compact and modular household sewage treatment device, usually installed under cabinets in kitchens, bathrooms, etc., and is suitable for treating domestic sewage (such as washing water, kitchen wastewater, bathing water, etc.); such systems purify sewage through physical, biological or chemical means to make it meet the discharge or reuse standards, and are especially suitable for residences or small commercial premises with limited space and no centralized drainage system.

[0003] For the existing in-cabinet domestic sewage treatment system, reference can be specifically made to the Chinese patent with the publication number CN117228879A, which discloses in detail a small domestic sewage treatment device including a sedimentation tank, an anaerobic tank, a biological filter tank, a secondary sedimentation tank and a clear water tank arranged in sequence. The domestic sewage of each rural household intercepts particulate pollutants and scum through the sedimentation tank, and at the same time degrades part of the organic matter through anaerobic digestion; the water discharged from the anaerobic tank flows into the biological filter tank by gravity. The sedimentation tank and the anaerobic tank perform preliminary treatment on the sewage to avoid large suspended solids from entering the biological filter tank and causing blockage, and at the same time perform preliminary removal of pollutants such as nitrogen, phosphorus and organic matter in the sewage. After flowing into the biological filter tank, it is subjected to deep treatment, and then the water is discharged into the secondary sedimentation tank for sedimentation and separation of mud and water before being discharged. The sludge deposited in the sedimentation tank and the secondary sedimentation tank is regularly cleaned and used as agricultural fertilizer. When garden irrigation is needed, the sewage in the anaerobic tank and the secondary sedimentation tank can be used; the clear water flowing out of the clear water tank can be used for washing clothes and vegetables, etc., so as to realize the treatment of sewage and the full reuse of water resources.

[0004] Although the existing miniaturized domestic sewage treatment system can effectively treat domestic sewage, it cannot separate solid waste from sewage during the sewage treatment process. The accumulation of solid waste at the bottom of the device during long-term use will lead to a reduction in the efficiency of the device in treating sewage; therefore, an in-cabinet domestic sewage treatment system and method are proposed for the above problems.

[0017] S2. After sedimentation, the sewage is stratified. The lighter - specific - gravity grease floats above the water. The sewage and grease are separated and discharged through the oil - water separation module. The grease is discharged from the oil discharge port.

[0018] S3. The separated sewage contacts the filler module inside the device main body, and the organic matter in the sewage is decomposed by the microorganisms in the filler module.

[0019] S4. The treated sewage is discharged from the device main body through the sewage discharge port.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. Through the structural design of the solid-liquid separation module, the present invention realizes the function of separating solid waste from domestic sewage, and solves the problem that although the existing miniaturized domestic sewage treatment system can effectively treat domestic sewage, it cannot separate solid waste from sewage during the sewage treatment process. During long-term use, the accumulation of solid waste at the bottom of the device will reduce the efficiency of the device in treating sewage. Most existing kitchen domestic sewage treatment devices directly crush solid waste and then discharge it into the sewer together with the sewage. This treatment method will increase the treatment load of the sewage treatment plant, and the residue of solid waste is likely to block the pipeline after long-term use. The solid-liquid separation module can separate solid waste from sewage, effectively avoiding the situation of pipeline blockage after long-term use. By regularly dumping the solid waste, the treatment burden on the sewage treatment plant can be effectively reduced;

[0022] 2. Through the structural design of the anti-reflux component, the present invention realizes the function of automatically opening under the action of gravity when sewage enters the device from the water inlet and automatically closing when there is no sewage, which can effectively prevent the odor of sewage inside the device from entering the home from the water inlet and keep the air in the home fresh;

[0023] 3. Through the structural design of the dosing module, the present invention realizes the function of automatically putting a chlorine tablet into the device when the collection basket is pulled out from the inside of the device main body. By regularly dumping the solid waste inside the collection basket, automatic dosing into the inside of the device main body can be achieved. Compared with the traditional automatic dosing device that uses a timer and a motor and other structural combinations for regular dosing, the cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment

[0044] Please refer to Figures 1-16As shown, a built-in cabinet domestic sewage treatment system and method, including a device main body 1; an inlet 2 is provided at the top of the device main body 1, a sewage outlet 3 is provided on the left side of the device main body 1, and an oil drain port 4 is also provided on the left side of the device main body 1. A solid-liquid separation module is arranged inside the device main body 1, and the solid-liquid separation module is used to separate solid waste in domestic sewage. A dosing module is arranged at the front end of the solid-liquid separation module. An oil-water separation module is also arranged inside the device main body 1, and the oil-water separation module is used to separate oil and sewage in domestic sewage. The specific structure of the oil-water separation module can refer to the Chinese patent with the publication number CN114504845B. The specific structure of the oil-water separation module in this case is similar to it and has the same principle. A filler module is arranged at the bottom end inside the device main body 1. The components of the filler module can specifically refer to the Chinese patent with the publication number CN105130008B. The filler module is used to decompose organic matter in sewage; the solid-liquid separation module includes an anti-backflow component and a separation component. The anti-backflow component is arranged inside the inlet 2, and the separation component is arranged at the bottom end of the anti-backflow component. The anti-backflow component includes a check valve plate 31, the check valve plate 31 is rotatably connected to the inner wall of the inlet 2, a torsion spring 32 is arranged between the check valve plate 31 and the inner wall of the inlet 2, a first installation groove 33 is opened on the left side of the check valve plate 31, a first steel sheet 34 is fixedly connected inside the first installation groove 33, the first steel sheet 34 is attracted to a first magnet 35, and the first magnet 35 is fixedly connected to the inner wall of the inlet 2. One end of the torsion spring 32 is fixedly connected to the check valve plate 31, and the other end of the torsion spring 32 is fixedly connected to the inner wall of the inlet 2. The separation component includes a collection basket 36, the collection basket 36 is arranged inside the device main body 1, the collection basket 36 is slidably connected to a slide rail 37, the slide rail 37 is fixedly connected to the inner wall of the device main body 1, a coarse filter plate 38 is fixedly connected inside the collection basket 36, the coarse filter plate 38 is designed in a "V" shape, and a fine filter plate 39 is fixedly connected to the bottom end of the collection basket 36;

[0045] During operation, sewage enters the inside of the device main body 1 through the inlet 2. The sewage impacts the check valve plate 31 to make the check valve plate 31 rotate downward, so that the first steel sheet 34 fixedly connected inside the first installation groove 33 and attracted to the first magnet 35 is separated from the first magnet 35 under the action of the impact force. As the check valve plate 31 rotates, at this time, the check valve plate 31 releases the blockage of the sewage, and the sewage flows into the inside of the collection basket 36. When the check valve plate 31 rotates downward, it drives the fixedly connected torsion spring 32 to synchronously generate elastic deformation due to torsion. When the sewage stops flowing in, the impact force of the sewage on the check valve plate 31 disappears. At this time, the check valve plate 31 rotates to its original position under the restoring force of the torsion spring 32, and drives the fixedly connected first steel sheet 34 to also rotate to its original position and be attracted to the first magnet 35, so as to seal the inlet 2 to prevent the odor of the sewage from surging through the inlet 2.

[0046] Further, movable slots 40 are provided at both the front and rear ends on the right side of the collection basket 36. A first spring 41 is arranged inside the movable slot 40, and a fixed block 42 is also inserted into the movable slot 40. The fixed block 42 is engaged with a fixed slot 43 which is provided on the device main body 1. A pulling plate 44 is fixedly connected to the right side of the fixed block 42. One end of the first spring 41 is fixedly connected to the fixed block 42, and the other end of the first spring 41 is fixedly connected to the inner wall of the movable slot 40;

[0047] During operation, when sewage enters the interior of the collection basket 36, it first contacts the coarse filter plate 38. Through the mesh holes provided on the coarse filter plate 38, larger solid wastes are left above the coarse filter plate 38, and smaller solid wastes continue to flow downward with the sewage and contact the fine filter plate 39. Smaller solid wastes are further intercepted through the fine mesh holes provided on the fine filter plate 39, and only the sewage enters the interior of the device main body 1. When the solid wastes in the collection basket 36 accumulate excessively after long-term use, first pull the two pulling plates 44, so that the pulling plates 44 drive the fixedly connected fixed blocks 42 to move synchronously inside the movable slots 40, release the engagement with the fixed slots 43 and compress the first spring 41, causing the first spring 41 to undergo elastic deformation. After the two pulling plates 44 are both disengaged from the fixed slots 43, pull the collection basket 36 to the right to remove the collection basket 36 from the interior of the device main body 1. After removing the collection basket 36, pour out the solid wastes inside the collection basket 36, and after rinsing the coarse filter plate 38 and the fine filter plate 39 with clean water, they can be reinstalled into the interior of the device main body 1 for use. When installing the collection basket 36, first align the collection basket 36 with the slide rail 37, and then insert the collection basket 36 into the interior of the device main body 1. When the collection basket 36 is inserted into the interior of the device main body 1, the device main body 1 exerts pressure on the inclined surface provided on the fixed block 42, causing the fixed block 42 to move into the interior of the movable slot 40 under the action of the pressure and compress the first spring 41, causing the first spring 41 to undergo elastic deformation under the action of the pressure. When the collection basket 36 is completely inserted into the interior of the device main body 1, the pressure of the device main body 1 on the fixed block 42 disappears. At this time, the fixed block 42 moves to its original position under the restoring force of the first spring 41 and engages with the fixed block 42 to fix the collection basket 36. A sealing ring is provided at the joint between the collection basket 36 and the device main body 1 for sealing to prevent the odor of sewage from escaping from the joint between the collection basket 36 and the device main body 1 or sewage from overflowing from the joint.

[0048] Further, the drug delivery module includes a second installation groove 45 opened at the top end of the device main body 1. A push rod 46 is provided at the top end of the second installation groove 45. Second steel sheets 47 are fixedly connected to the left and right sides of the bottom end of the push rod 46. The second steel sheets 47 are attracted to the second magnetic blocks 48. The second magnetic blocks 48 are fixedly connected to the left and right sides near the top end of the inner wall of the second installation groove 45. A medicine storage box 49 is inserted into the second installation groove 45. A cover plate 50 is provided at the top end of the medicine storage box 49. Connecting blocks 51 are fixedly connected to the left and right sides of the top end of the cover plate 50. The connecting blocks 51 are inserted into the connecting grooves 52 and attracted to the third magnetic blocks 53. The connecting grooves 52 are opened at the left and right sides of the inner wall top end of the medicine storage box 49. The third magnetic blocks 53 are fixedly connected to the inside of the connecting grooves 52. A left positioning block 54 is fixedly connected to the left side of the medicine storage box 49. A right positioning block 55 is fixedly connected to the right side of the medicine storage box 49. A bottom plate 56 is provided at the bottom end of the medicine storage box 49. A first sliding groove 57 is opened on the bottom plate 56. A first guiding rod 58 is fixedly connected to the inside of the first sliding groove 57. A first sliding block 59 is slidably connected to the outside of the first guiding rod 58. The top end of the first sliding block 59 is fixedly connected to the bottom end of the medicine storage box 49. A second spring 60 is also wound around the outside of the first guiding rod 58. The front end of the second spring 60 is fixedly connected to the first sliding block 59. The rear end of the second spring 60 is fixedly connected to the inner wall of the first sliding groove 57. A chlorine tablet 61 is provided inside the medicine storage box 49. A pushing component is provided at the rear side of the medicine storage box 49 for fixing the chlorine tablet 61. An ejecting component is also provided inside the medicine storage box 49 for ejecting the chlorine tablet 61;

[0049] During operation, a protrusion is provided at the center position of the rear end of the bottom plate 36. When the collection basket 36 is inside the device main body 1, the protrusion abuts against the front end of the collection basket 36. After the collection basket 36 is pulled out of the inside of the device main body 1, the extrusion of the protrusion at the rear end of the bottom plate 56 by the collection basket 36 disappears. At this time, the bottom plate 56 moves in the direction of the rear end of the device main body 1 under the restoring force of the second spring 60, opening the bottom end of the medicine storage box 49. When the bottom plate 56 is squeezed by the collection basket 36 to close the medicine storage box 49, the two sets of push plates 81 on the left and right sides of the top end of the bottom plate 56 are blocked by the bottom plate 56 and cannot fall. The push plates 81 are arranged inside the third storage groove 82. After the bottom plate 56 moves to the limit in the direction of the rear end of the device main body 1, the bottom plate 56 simultaneously releases the block on the push plates 81. At this time, the push plates 81 move downward under the action of gravity, driving the second rack 80 to move downward synchronously, causing the second rack 80 to drive the meshing transmission gear 79 to rotate. The transmission gear 79 drives the first rack 78 to move downward, so that the push block 74 fixedly connected to the first rack 78 moves downward under the dual action of the restoring force of the fifth spring 75 and the gravity of the push plate 81, causing the push block 74 to move downward and push the rightmost chlorine tablet 61 inside the medicine storage box 49 to move downward and fall from the gap opened at the bottom end of the medicine storage box 49. The bottom end of the push block 74 is provided with an inclined surface, which will slightly push or squeeze the second chlorine tablet 61 on the right side inside the medicine storage box 49 to the left when moving downward, causing it not to contact the rightmost chlorine tablet 61, avoiding the rightmost chlorine tablet 61 being unable to automatically fall from the inside of the medicine storage box 49 due to the action of friction. When the collection basket 36 is reinstalled inside the device main body 1, the bottom plate 56 is pushed back to its original position by the collection basket 36, and at the same time drives the push plates 81 and the push block 74 to move back to their original positions synchronously. At this time, the push block 74 releases the block on the chlorine tablets 61, and multiple groups of chlorine tablets 61 are pushed by the front top block 72 to move toward the front end of the medicine storage box 49, facilitating the next delivery of the chlorine tablets 61.

[0050] Further, the pushing component includes a rear top block 62 which is inserted at the rear side of the medicine storage box 49. The top end of the rear top block 62 is fixedly connected with a second sliding groove 63. Inside the second sliding groove 63, a second guiding rod 64 is fixedly connected. The outer side of the second guiding rod 64 is slidably connected with a second sliding block 65. A third spring 66 is wound around the outer side of the second sliding block 65. At the front end of the rear top block 62, a first receiving groove 67 is formed. An active block 68 is inserted inside the first receiving groove 67. And a fourth spring 69 is also arranged inside the first receiving groove 67. Third sliding grooves 70 are formed at the upper and lower ends of the active block 68. Inside the third sliding grooves 70, third sliding blocks 71 are slidably connected. The third sliding blocks 71 are fixedly connected to the inner wall of the first receiving groove 67. The front end of the active block 68 is fixedly connected with a front top block 72. One end of the third spring 66 is fixedly connected with the second sliding block 65, and the other end of the third spring 66 is fixedly connected to the inner wall of the second sliding groove 63. The front end of the fourth spring 69 is fixedly connected with the rear end of the active block 68, and the rear end of the fourth spring 69 is fixedly connected to the inner wall of the first receiving groove 67. At a position near the front side at the top end inner wall of the medicine storage box 49, a second receiving groove 73 is formed. A pushing block 74 is inserted inside the second receiving groove 73. A fifth spring 75 is also arranged inside the second receiving groove 73. The bottom end of the fifth spring 75 is fixedly connected with the pushing block 74, and the top end of the fifth spring 75 is fixedly connected to the inner wall of the second receiving groove 73. A fourth sliding block 76 is fixedly connected to the inner wall of the second receiving groove 73. The fourth sliding block 76 is slidably connected inside a fourth sliding groove 77 which is formed at one side of the pushing block 74. The front end of the pushing block 74 is fixedly connected with a first rack 78. The first rack 78 meshes with a transmission gear 79 which is rotatably connected inside a third receiving groove 82.

The fifth sliding block 83 is slidably connected inside a fifth sliding groove 84 which is formed at a position near the bottom at the front end of the push plate 81;

[0051] During operation, when the chlorine tablets 61 inside the medicine storage box 49 are exhausted and need to be replenished, simply pull the ejector rod 46 upward to release the suction state between the second steel sheet 47 fixedly connected to the ejector rod 46 and the second magnet 48, and then the ejector rod 46 can be removed. A sealing ring is provided between the ejector rod 46 and the device main body 1 to prevent the odor of sewage from escaping from the joint between the ejector rod 46 and the device main body 1. After removing the ejector rod 46, pull the medicine storage box 49 upward from the inside of the second installation groove 45 to remove the medicine storage box 49 from the inside of the second installation groove 45. Then pull the cover plate 50 upward to separate the connecting block 51 fixedly connected to the cover plate 50 from the third magnet 53 fixedly connected inside the connecting groove 52, and then the connecting block 51 can be removed. Then insert a finger into the medicine storage box 49 and move the front top block 72 backward, driving the fixedly connected movable block 68 to move into the first storage groove 67 to the limit and squeezing the fourth spring 69. When the movable block 68 completely enters the first storage groove 67, the rear top block 62 moves backward synchronously with the front top block 72 under the action of the thrust. At this time, the second slider 65 slides inside the second chute 63, driving the third spring 66 to deform elastically until the rear top block 62 is also pushed to the limit. Then put new chlorine tablets 61 into the medicine storage box 49 and release the front top block 72 to complete the replenishment of the chlorine tablets 61. At this time, the rear top block 62 moves forward under the restoring force of the third spring 66, driving the front top block 72 to move synchronously. At the same time, the front top block 72 also moves forward under the restoring force of the fourth spring 69 until it contacts the chlorine tablets 61 and squeezes the chlorine tablets 61 to fix the chlorine tablets 61. The design of setting two groups of left positioning blocks 54 on the left side and one group of right positioning blocks 55 on the right side of the medicine storage box 49 has an anti-fooling effect, avoiding the situation of incorrect installation direction when installing the medicine storage box 49.
