[0037] like Figure 1 , 2 As shown in FIG. 3 , the auxiliary equipment for treating urban sewage by an activated mud method according to the present invention comprises:

[0038] A reaction box 101 is fixedly connected to one end of a plurality of fixed brackets 102. The upper portion of the side wall of the reaction box 101 is fixedly connected to and communicated with one end of a sewage inlet pipe 103.

[0044] The present invention uses the wireless communication module to enable the user to smoothly control the rotation speed of the motor 201, thereby controlling the reciprocating rotation speed of the stirring rod 311, and ultimately achieving control of the cutting speed of the raw material.

[0045] The number of the fixing brackets 102 may be 3, 4, 5, 6, 7, 8, 9 or more.

[0046] The sliding mechanism includes a first slider 301, a first guide rail 302, a first rack 303, a first gear 304, a first through hole 305, a first rotating shaft 306, a first spherical shell 307, a second through hole 308, a rotating box 309, a first round table 310, and a second gear 312;

[0047] For further explanation of the present invention, see Figure 4 , 5 ,

[0048] The stirring mechanism 300 includes a motor 201, an output shaft 202, a first slider 301, a first guide rail 302, a first rack 303, a first gear 304, a first through hole 305, a first rotating shaft 306, a first spherical shell 307, a second through hole 308, a rotating box 309, a first truncated table 310, a second gear 312, and a fourth fixing plate 313;

[0049] The fixed bracket 102 is fixedly connected to the motor 201, the output shaft 202 of the motor 201 is drivingly connected to the first slider 301, the first slider 301 is arranged in the first guide rail 302 and moves along it, one end of the first guide rail 302 is fixedly connected to the first round table 310, the first round table 310 is installed at the bottom of the reaction box 101 through a bearing, the first slider 301 is fixedly connected to the first rack 303, the first rack 303 is meshed with the first gear 304, the first gear 304 is installed at one end of the fourth fixed plate 313 through a bearing, the other end of the fourth fixed plate 313 is fixedly connected to the first round table 310, the first gear 304 is provided with the first through hole 305, the first rotating shaft 306 rotating along the first through hole 305 is arranged, the middle part of the first rotating shaft 306 is coaxially fixed with the second gear 312, and the second gear 312 is meshed with the first rack 303;

[0050] One side of the first rotating shaft 306 is coaxially fixed with the first spherical shell 307, the first spherical shell 307 is sealed and arranged in the second through hole 308 and rotates along it, the second through hole 308 is opened on the side wall of the rotating box 309, one end of the rotating box 309 is sealed and fixedly connected to the first truncated table 310, and one end of the first rotating shaft 306 is fixedly connected to the stirring rod 311.

[0051] The motor 201 described in the present invention drives the first gear 304 to rotate through the output shaft 202, thereby driving the synchronous rotation of the first rotating shaft 306, and finally realizing the rotation of the stirring rod 311 along the center of the second gear 312, so that the stirring rod 311 can fully mix the sewage and activated sludge mixed outside the rotating box 309 in the reaction box 101.

[0052] Among them, the motor 201 drives the first slider 301 to reciprocate along the length direction of the first guide rail 302 through the output shaft 202, and drives the first rack 303 to move up and down through the first slider 301. The reciprocating motion of the first rack 303 drives the rotation of the first gear 304, and the swing of the first rotating shaft 306 is realized through the first through hole 305 opened on the first gear 304. During the swinging of the first rotating shaft 306, through the cooperation of the two first spherical shells 307 and the second through hole 308, and the meshing of the first rack 303 and the second gear 312, the first rack 303 can drive the synchronous rotation of the second gear 312 during the up and down movement.

[0055] The first through hole 305 and the first gear 304 are not coaxially arranged, and the axis of the first through hole 305 is not parallel to the axis of the first gear 304 , so that the rotation of the first gear 304 can smoothly drive the first rotating shaft 306 to complete the rotation through the first through hole 305 .

[0056] The rotating box 309 is a square barrel whose bottom is sealed and fixed to the first truncated table 310, and the first spherical shell 307 and the second through hole 308 are sealed and overlapped, so that the sewage in the reaction box 101 cannot enter the rotating box 309, thereby ensuring the normal operation of gears and other components.

[0057] Part of the stirring rod 311 is above the water surface during the movement, so that the stirring rod 311 can mix some air into the sewage mixture during the stirring process, thereby increasing the dissolved oxygen content of the mixture.

[0058] For further explanation of the present invention, see Figure 6 , 7 ,

[0063] The motor 201 drives the synchronous rotation of the third gear 401 and the fourth gear 402 through the output shaft 202, and the rotation of the fourth gear 402 further drives the self-rotation of the rotating box 309, and then drives the first bevel gear 404 to revolve around the axis of the rotating box 309 through the rotating box 309. During the revolution of the first bevel gear 404, the self-rotation of the first bevel gear 404 is achieved by meshing with the first gear ring 405.

The first guide rod 505 moves up and down along the third through hole 506, and the up and down movement of the first guide rod 505 drives the up and down movement of the third connecting rod 508 and the third pin shaft 509, so that the third pin shaft 509 smoothly drives the first guide plate 511 and the second slider 512 to reciprocate along the length direction of the second guide rail 513 through the second guide groove 510, and through the elastic force of the first spring 519, the first scraper 520 can scrape the sludge above the water filter plate 515 when the first guide plate 511 moves left and right, thereby accelerating the filtration of sewage.

[0084] The trajectory shape of the first guide groove 503 is wavy, N-shaped, W-shaped, M-shaped, or V-shaped, so that the first ring 502 can drive the first guide rod 505 to move up and down along the third through hole 506 through the interaction between the first guide groove 503 and the second pin shaft 504 during rotation.

[0085] The cross-sectional shape of the first guide rod 505 is a square, and the cross-sectional shape of the inner surface of the third through hole 506 is a square matching the cross-sectional shape of the first guide rod 505 , so that the first guide rod 505 can only slide up and down along the third through hole 506 .

[0086] Among them, the structure composed of the third pin shaft 509, the second guide groove 510, the first guide plate 511, the second slider 512, and the second guide rail 513 has two groups symmetrically distributed front and back about the center of the third connecting rod 508, so that the left and right movement process of the first guide plate 511 is smoother.

[0087] The second slider 512 is a dovetail slider, and the second guide rail 513 is a dovetail guide rail, thereby ensuring that the second slider 512 can only reciprocate along the length direction of the second guide rail 513 .

[0088] The first spring 519 is always in a compressed state, so that when the first guide plate 511 moves left and right, the first scraper 520 can always fit with the upper surface of the water filter plate 515 under the elastic force of the first spring 519 .

[0089] Among them, the water filter plate 515 is configured to be inclined, and its inclination direction is from top to bottom from close to the reaction box 101 to away from the reaction box 101, and the first scraper 520 and the water filter plate 515 are always kept vertical, so that the first scraper 520 can scrape the sludge on the surface of the water filter plate 515 more thoroughly.

[0090] Among them, the installation, driving and control methods of the first pump body 525 are existing technologies and will not be repeated here.

[0091] Among them, the power supply of the second solenoid valve 523 is fixedly connected to the outer surface of the reaction box 101, and is connected to the user terminal through a wireless communication module, so that the user can control the on and off of the second solenoid valve 523 to control whether the sewage mixture in the reaction box 101 flows into the filter tank 514 to complete filtering and sedimentation.

[0092] For further explanation of the present invention, see Fig. 9 ,

[0093] The reaction box 101 is also provided with an oxygen supply mechanism 600, which includes a high-pressure oxygen supply pipe 601, a ring pipe 602, a flow distribution pipe 603, and a flow equalization chamber 604;

[0094] The bottom of the reaction box 101 is fixedly connected to the flow equalizing chamber 604, and a plurality of ventilation holes 605 are evenly opened on the top of the flow equalizing chamber 604. The flow equalizing chamber 604 is fixedly connected and communicated with one end of a plurality of diversion air pipes 603, and the other end of the diversion air pipe 603 is fixedly connected and communicated with the annular tube 602, and the annular tube 602 is fixedly connected and communicated with one end of the high-pressure oxygen supply pipe 601, and the other end of the high-pressure oxygen supply pipe 601 is fixedly connected and communicated with the high-pressure oxygen tank.

[0095] The oxygen in the high-pressure oxygen tank of the present invention is transported to the flow equalization chamber 604 through the high-pressure oxygen supply pipe 601, the annular pipe 602, and the diversion air pipe 603, and the oxygen is evenly transported to the activated mud and sewage mixture in the reaction box 101 through the evenly distributed air holes 605. The oxygen and the organic matter in the sewage cause the microorganisms in the activated mud to multiply in large numbers, thereby degrading the organic matter in the sewage and achieving sewage purification.

[0096] The flow equalizing chamber 604 is in the shape of a ring and is coaxially fixed to the bottom of the reaction box 101 , so that the oxygen delivered to the flow equalizing chamber 604 can be evenly delivered to the reaction box 101 .

[0097] The number of the diversion air pipes 603 can be 4, 5, 6, 7, 8, 9 or more.

[0098] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
