Detailed implementation manners

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0062] In the embodiments of the present invention, please refer to Figures 1 to 10 , a sewage treatment device, including a filtration tank 1, the filtration tank 1 is connected to a sewage inlet pipe 2, and further includes:

[0063] An installation bracket 3, placed inside the filtration tank 1;

[0064] A membrane separation component 4, rotatably connected to the installation bracket 3, for filtering and separating solid impurities in the sewage;

[0065] An outlet pipe 5, rotatably connected to the top of the membrane separation component 4 and communicating with its interior, the outlet pipe 5 is connected to the installation bracket 3;

[0066] A liquid extraction pump 6, communicating with the interior of the outlet pipe 5;

[0067] An aeration mechanism 7, connected to the bottom of the membrane separation component 4, for aerating the sewage;

[0068] A cleaning mechanism 8, for cleaning the solid impurities adhering to the membrane separation component 4, the cleaning mechanism 8 includes:

[0069] A limiting rod 81, connected to the membrane separation component 4;

[0070] A sliding sleeve 82, slidably connected to the limiting rod 81;

[0071] A cleaning roller 83, rotatably connected to the sliding sleeve 82;

[0072] A telescopic member 84, one end connected to the installation bracket 3;

[0073] A longitudinal reciprocating assembly 85, connected to the other end of the telescopic member 84 and connected to the sliding sleeve 82, for driving the sliding sleeve 82 to reciprocate longitudinally;

[0074] A reciprocating deflection assembly 86, one end connected to the telescopic member 84 and the other end connected to the membrane separation component 4, for driving the membrane separation component 4 to rotate reciprocally;

[0075] A rotating assembly 87, one end connected to the membrane separation component 4 and the other end connected to the cleaning roller 83, for driving the cleaning roller 83 to rotate.

[0076] Sewage enters the filtration tank 1 through the sewage inlet pipe 2. First, it undergoes filtration separation through the membrane separation module 4. The membrane separation module 4 intercepts solid impurities in the sewage through its microporous structure. The filtered water body enters the interior of the membrane separation module 4. The liquid extraction pump 6 pumps out the filtered water through the outlet pipe 5, realizing the separation of water and solid impurities for subsequent treatment. The aeration mechanism 7 conducts aeration to evenly distribute air in the sewage, increasing the dissolved oxygen content and promoting the decomposition of organic matter in the sewage. At the same time, the airflow blows the impurities adhering to the surface of the membrane separation module 4, preventing membrane pore blockage and improving the sewage treatment effect. As the filtration progresses, too many impurities adhere to the surface of the membrane separation module 4, and the filtration effect deteriorates. At this time, the cleaning step is entered. The liquid extraction pump 6 reversely sends clean water into the membrane separation module 4, and the clean water flows out from the membrane separation module 4 to backwash the solid impurities adhering to its surface, causing the impurities to detach from the membrane separation module 4. At the same time, the aeration mechanism 7 blows out an air current, and the air current is in the opposite direction to the flushing water for counter-flushing, increasing the water flow impact force and generating turbulent flow to improve the flushing effect. The telescopic member 84 reciprocates, driving the reciprocating deflection assembly 86 to move. The reciprocating deflection assembly 86 drives the membrane separation module 4 to reciprocally rotate, causing the sewage to generate turbulent flow and improving the impurity detachment effect. At the same time, the telescopic member 84 drives the longitudinal reciprocating assembly 85 to move. The longitudinal reciprocating assembly 85 drives the sliding sleeve 82 to longitudinally reciprocate. The sliding sleeve 82 drives the cleaning roller 83 to longitudinally reciprocate. The rotating assembly 87 drives the cleaning roller 83 to rotate to clean the surface of the membrane separation module 4 and improve the cleaning effect.

[0077] As an embodiment of the present invention, please refer to Figure 2 、 Figure 3 and Figure 5 , the aeration mechanism 7 includes:

[0078] The connecting air pipe 71 is connected to the bottom of the membrane separation module 4 and is rotatably connected thereto. The connecting air pipe 71 is connected to the mounting bracket 3. An electromagnetic valve is provided in the connecting air pipe 71. The connecting air pipe 71 is connected to the aerator;

[0079] The universal joint seat 72 is internally connected to the connecting air pipe 71. A plurality of groups of the universal joint seats 72 are provided;

[0080] The universal ball 73 is movably connected to the universal joint seat 72 and is internally connected thereto;

[0081] The aeration pipe 74 is internally connected to the universal ball 73. A plurality of groups of aeration holes are provided on the aeration pipe 74.

[0082] The connecting air pipe 71 is connected to an aerator (not shown in the figure). The compressed air generated by the aerator enters the universal joint 72 through the connecting air pipe 71, and is evenly released into the sewage through the air holes on the universal ball 73 and the aeration pipe 74. During the aeration process, the air is fully mixed with the sewage, increasing the dissolved oxygen in the water, promoting the decomposition of organic matter in the sewage, and also helping to prevent the micropores of the membrane separation module 4 from being blocked. Through the design of the universal joint 72 and the universal ball 73, the flexible arrangement of the aeration pipe 74 can be realized.

[0083] As an embodiment of the present invention, please refer to Figures 1 to 3 、 Figures 6 to 9 , the longitudinal reciprocating assembly 85 includes:

[0084] A sliding folding rod 851, one end of which is connected to the telescopic member 84;

[0085] A connecting frame 852, which is connected to the mounting bracket 3 and is slidably connected to the sliding folding rod 851;

[0086] A piston 853, which is located inside the connecting frame 852 and is slidably connected thereto. The piston 853 is connected to the other end of the sliding folding rod 851;

[0087] A communication assembly 854, one end of which is connected to the connecting frame 852 and is in communication with its interior;

[0088] A telescopic cylinder 855, which is in communication with the other end of the communication assembly 854 and is connected to a group of the sliding sleeves 82;

[0089] A rotating sleeve 856, which is rotatably connected to the cleaning roller 83;

[0090] A hinge rod 857, both ends of which are respectively rotatably connected to two adjacent rotating sleeves 856;

[0091] The communication assembly 854 includes:

[0092] An air outlet hose 8541, one end of which is in communication with the interior of the connecting frame 852 and the other end of which is in communication with the interior of the telescopic cylinder 855. A check valve one is provided in the air outlet hose 8541;

[0093] An air inlet pipe 8542, which is in communication with the interior of the connecting frame 852. A check valve two is provided in the air inlet pipe 8542;

[0094] An air inlet hose 8543, one end of which is in communication with the interior of the connecting frame 852 and the other end of which is in communication with the interior of the telescopic cylinder 855. A check valve three is provided in the air inlet hose 8543;

[0095] An air outlet pipe 8544, which is in communication with the interior of the connecting frame 852. A check valve four is provided in the air outlet pipe 8544;

[0096] Balanced through holes 8545 are opened on the connection frame 852. There are two groups of the balanced through holes 8545, and they are located on both sides of the piston 853.

[0097] The control detector 8546 is connected to the mounting bracket 3 and is electrically connected to the first check valve, the second check valve, the third check valve, and the fourth check valve.

[0098] The communication ports of the air outlet hose 8541 and the air inlet pipe 8542 with the connection frame 852 are located on one side of the piston 853, and the communication ports of the air inlet hose 8543 and the air outlet pipe 8544 with the connection frame 852 are located on the other side of the piston 853.

[0099] When the cleaning roller 83 is located at the top of the membrane separation module 4, the control detector 8546 keeps the third check valve and the fourth check valve in the closed state, and the first check valve and the second check valve in the open state.

[0100] The telescopic member 84 drives the sliding folding rod 851 to reciprocate horizontally. The sliding folding rod 851 drives the piston 853 to reciprocate horizontally, sucking the outside air into the interior of the connection frame 852 through the air inlet pipe 8542, and then sending it into the interior of the telescopic cylinder 855 through the air outlet hose 8541, so that the telescopic cylinder 855 extends, driving the sliding sleeve 82 to move downward along the sliding folding rod 851, so that the cleaning roller 83 moves downward to clean the membrane separation module 4.

[0101] When the cleaning roller 83 moves to the bottom of the membrane separation module 4, the control detector 8546 keeps the third check valve and the fourth check valve in the open state, and the first check valve and the second check valve in the closed state.

[0102] The telescopic member 84 drives the sliding folding rod 851 to reciprocate horizontally. The sliding folding rod 851 drives the piston 853 to reciprocate horizontally, sucking the air in the telescopic cylinder 855 into the interior of the connection frame 852 through the air inlet hose 8543, and then flowing it into the outside through the air outlet pipe 8544, so that the telescopic cylinder 855 retracts, driving the sliding sleeve 82 to move upward along the sliding folding rod 851, so that the cleaning roller 83 moves upward to clean the membrane separation module 4.

[0103] In this embodiment, the balanced through holes 8545 ensure that air can enter or flow out of the connection frame 852. Moreover, the aperture of the balanced through holes 8545 is relatively small, so that when the first check valve and the second check valve are in the open state, part of the gas in the connection frame 852 flows out from the balanced through holes 8545, and part of the gas enters the interior of the telescopic cylinder 855 through the air outlet hose 8541.

[0104] As an embodiment of the present invention, please refer to Figures 1 to 3 、 Figure 6 , the reciprocating deflection assembly 86 includes:

[0105] The first toothed plate 861 is connected to the telescopic member 84;

[0106] The first gear 862 is connected to the membrane separation assembly 4 and meshes with the first toothed plate 861.

[0107] The telescopic member 84 drives the first toothed plate 861 to move horizontally back and forth. The first toothed plate 861 drives the first gear 862 to rotate back and forth. The first gear 862 drives the membrane separation assembly 4 to rotate back and forth, so that the membrane separation assembly 4 generates an impact force on the water flow, improving the impurity detachment effect.

[0108] As an embodiment of the present invention, please refer to Figures 1 to 3 、 Figure 6 and Figure 10 , the rotating assembly 87 includes:

[0109] The second gear 871 is connected to the cleaning roller 83;

[0110] The second toothed plate 872 is connected to the membrane separation assembly 4 and meshes with the second gear 871.

[0111] During the longitudinal movement of the cleaning roller 83, it drives the second gear 871 to move longitudinally synchronously. Since the second gear 871 meshes with the second toothed plate 872, the second gear 871 rotates self - rotatably, and the second gear 871 drives the cleaning roller 83 to rotate, cleaning the membrane separation assembly 4.

[0112] As an embodiment of the present invention, please refer to Figure 2 、 Figure 3 and Figure 5 , it further includes:

[0113] The connecting rope 9, one end is connected to the aeration pipe 74, and the other end is connected to the membrane separation assembly 4.

[0114] When the membrane separation assembly 4 rotates, driven by the connecting rope 9, the aeration pipe 74 rotates synchronously, improving the aeration range. At the same time, the connecting rope 9 has a certain length, so that the aeration pipe 74 has a certain inclination, making the air flow direction inclined upward, ensuring that impurities are far away from the membrane separation assembly 4.

[0115] The working principle of the present invention is as follows: Sewage enters the filtration tank 1 through the sewage inlet pipe 2, first passes through the membrane separation assembly 4 for filtration and separation. The membrane separation assembly 4 intercepts solid impurities in the sewage through its microporous structure. The filtered water body enters the interior of the membrane separation assembly 4. The liquid extraction pump 6 pumps out the filtered water through the outlet pipe 5, realizing the separation of water and solid impurities for subsequent treatment. The compressed air generated by the aerator enters the universal joint seat 72 through the connecting air pipe 71, and is evenly released into the sewage through the universal ball 73 and the aeration holes on the aeration pipe 74. During the aeration process, the air is fully mixed with the sewage, increasing the dissolved oxygen in the water and promoting the decomposition of organic matter in the sewage;

[0116] As the filtration progresses, excessive impurities adhere to the surface of the membrane separation module 4, and the filtration effect deteriorates. At this time, the cleaning step is entered. The liquid extraction pump 6 reversely feeds clear water into the membrane separation module 4, and the clear water flows out of the membrane separation module 4 to backwash the solid impurities adhering to its surface, causing the impurities to detach from the membrane separation module 4. At the same time, the aeration mechanism 7 blows out airflows, and the airflows are in the opposite direction to the flushing water for counter-flushing, increasing the impact force of the water flow and generating turbulent flow at the same time, improving the flushing effect. The telescopic member 84 reciprocates, driving the first toothed plate 861 to reciprocate horizontally. The first toothed plate 861 drives the first gear 862 to rotate reciprocally, and the first gear 862 drives the membrane separation module 4 to rotate reciprocally, causing the membrane separation module 4 to generate an impact force with the water flow and improving the impurity detachment effect;

[0117] When the cleaning roller 83 is located at the top of the membrane separation module 4, the control detector 8546 controls the check valve three and the check valve four to be in the closed state, and the check valve one and the check valve two to be in the open state;

[0118] The telescopic member 84 drives the sliding folding rod 851 to reciprocate horizontally. The sliding folding rod 851 drives the piston 853 to reciprocate horizontally, sucking outside air into the inside of the connecting frame 852 through the air inlet pipe 8542, and then sending it into the inside of the telescopic cylinder 855 through the air outlet hose 8541, causing the telescopic cylinder 855 to extend and driving the sliding sleeve 82 to move downward along the sliding folding rod 851, causing the cleaning roller 83 to move downward to clean the membrane separation module 4;

[0119] When the cleaning roller 83 moves to the bottom of the membrane separation module 4, the control detector 8546 controls the check valve three and the check valve four to be in the open state, and the check valve one and the check valve two to be in the closed state;

[0120] The telescopic member 84 drives the sliding folding rod 851 to reciprocate horizontally. The sliding folding rod 851 drives the piston 853 to reciprocate horizontally, sucking the air inside the telescopic cylinder 855 into the inside of the connecting frame 852 through the air inlet hose 8543, and then flowing it into the outside through the air outlet pipe 8544, causing the telescopic cylinder 855 to retract and driving the sliding sleeve 82 to move upward along the sliding folding rod 851, causing the cleaning roller 83 to move upward to clean the membrane separation module 4.
