[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-4 The utility model provides an embodiment: an MBR integrated sewage device, including a sewage treatment tank 1, a water inlet pipe 2 is fixedly connected to the right end of the sewage treatment tank 1, a water filter grille 11 is fixedly connected to the right end of the inner wall of the water inlet pipe 2, a motor 3 is fixedly connected to the top of the water inlet pipe 2, a rotating shaft 4 is fixedly connected to the driving end of the motor 3, the rotating shaft 4 is connected to the dredging plate 9 through a reciprocating component, and a plurality of dredging rods 10 are fixedly connected to the right end of the dredging plate 9, the reciprocating component includes an eccentric wheel 5 fixedly connected to the bottom end of the rotating shaft 4, an eccentric rod 6 is rotatably connected to the eccentric position of the bottom end of the eccentric wheel 5, a moving rod 7 is rotatably connected to the right end of the eccentric rod 6, a limiting block 8 is fixedly connected to the inner wall of the limiting block 8, the moving rod 7 is slidably connected to the inner wall of the limiting block 8, the left end of the dredging plate 9 is fixedly connected to the right end of the moving rod 7, the rotating shaft 4 is rotatably connected to the inner wall of the water inlet pipe 2, the dredging plate 9 is slidably connected to the inner wall of the water inlet pipe 2, and the dredging rod 10 corresponds to the pores of the water filter grille 11.

[0024] Specifically, when the sewage treatment tank 1 is used for a long time, the pores of the water filter grille 11 on the inner wall of the water inlet pipe 2 will be filled with sewage dirt. In this regard, in order to avoid this situation, when the sewage treatment tank 1 is used, the motor 3 is started, and the motor 3 drives the rotating shaft 4 to rotate, thereby driving the eccentric wheel 5 to rotate. The eccentric part of the eccentric wheel 5 drives the left end of the eccentric rod 6 to make a circular motion around the eccentric wheel 5, thereby driving the moving rod 7 to move back and forth. Because the moving rod 7 slides on the inner wall of the limiting block 8, the moving rod 7 can only move back and forth in a straight line. The moving rod 7 drives the dredging plate 9 to move back and forth, thereby driving the dredging rod 10 to reciprocate between the pores of the water filter grille 11, so that the dredging rod 10 pushes away the dirt between the pores of the water filter grille 11, dredges the water filter grille 11, avoids the blockage of the water inlet pipe 2, increases the rate at which sewage enters the sewage treatment tank 1, and makes the sewage be processed inside the sewage treatment tank 1 and then discharged from the outlet pipe 19.

[0025] The sewage treatment tank 1 is connected to a plurality of membrane frames 12 through a snap-on assembly, a plurality of tubular membranes 13 are fixedly connected to the inner wall of the membrane frame 12, a handle 14 is fixedly connected to the top of the membrane frame 12, the snap-on assembly includes a connecting rod 15 slidably connected to the front and rear sides of the inner wall of the membrane frame 12, a control rod 16 is fixedly connected to the top of the connecting rod 15, a clamping block 17 is fixedly connected to the opposite end of the connecting rod 15, the clamping block 17 fits with the clamping groove on the inner wall of the sewage treatment tank 1, a spring 18 is fixedly connected to the opposite end of the connecting rod 15, and the opposite end of the spring 18 is fixedly connected to the inner wall of the membrane frame 12, and a water outlet pipe 19 is fixedly connected to the left end of the sewage treatment tank 1.

[0026] Specifically, when the tubular membrane 13 is replaced and cleaned later, it is only necessary to slide the control rod 16 so that the control rod 16 drives the connecting rod 15 to move, thereby driving the block 17 to disengage from the slot on the inner wall of the sewage treatment tank 1, and then use the handle 14 to pull out the membrane frame 12 for replacement or cleaning. After the replacement or cleaning is completed, the membrane frame 12 can be directly inserted into the sewage treatment tank 1. Because the front end of the block 17 is arc-shaped, the control rod 16 is not required during insertion, which simplifies the operation process. During the insertion process, the block 17 will be squeezed by the inner wall of the sewage treatment tank 1, thereby driving the connecting rod 15 to squeeze the spring 18. When inserted into the correct position, the spring 18 will rebound the connecting rod 15, thereby driving the block 17 to enter the slot to fix the membrane frame 12, thereby achieving convenient replacement.

[0027] Working principle: When in use, start the motor 3, the motor 3 drives the rotating shaft 4 to rotate, thereby driving the eccentric wheel 5 to rotate, the eccentric part of the eccentric wheel 5 drives the left end of the eccentric rod 6 to make a circular motion around the eccentric wheel 5, and the right end of the eccentric rod 6 drives the moving rod 7 to move back and forth, and the limiting block 8 on the outer wall of the moving rod 7 ensures that the moving rod 7 moves in a straight line, and the moving rod 7 drives the dredging plate 9 to move back and forth, thereby driving the dredging rod 10 to reciprocate between the pores of the water filter grille 11, so that the dredging rod 10 pushes away the dirt between the pores of the water filter grille 11, avoiding the blockage of the water inlet pipe 2, and increasing the speed at which the sewage enters the sewage treatment tank 1. When the tubular membrane 1 is later When replacing or cleaning, it is only necessary to slide the control rod 16 so that the control rod 16 drives the connecting rod 15 to move, thereby driving the card block 17 to be separated from the card slot on the inner wall of the sewage treatment tank 1, and then use the handle 14 to pull out the membrane frame 12 for replacement or cleaning. After the replacement or cleaning is completed, the membrane frame 12 can be directly inserted into the sewage treatment tank 1. Because the front end of the card block 17 is arc-shaped, the control rod 16 can be used for insertion, which is convenient for operation. During the insertion process, the card block 17 will be squeezed, thereby driving the connecting rod 15 to squeeze the spring 18. When inserted to the correct position, the spring 18 will rebound the connecting rod 15, thereby driving the card block 17 to enter the card slot to fix the membrane frame 12.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
