Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and specifically to an integrated wastewater treatment equipment. Background Technology

[0002] Wastewater treatment is a technological system that purifies water bodies using physical, chemical, and biological methods to meet discharge or reuse standards. It is mainly divided into two categories: industrial wastewater treatment and domestic wastewater treatment. The treatment process includes three stages: primary treatment removes suspended solids using physical methods such as screens and sedimentation; secondary treatment uses biological technologies such as activated sludge and biofilm processes to degrade organic matter; and tertiary treatment uses technologies such as membrane separation and ion exchange for deep purification.

[0003] Wastewater treatment is generally classified into industrial wastewater treatment and domestic wastewater treatment based on its source. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is wastewater generated in daily life. It refers to a complex mixture of various forms of inorganic and organic matter, including floating and suspended solid particles of various sizes, colloidal and gel-like diffuses, pure solutions, etc. Among them, agricultural wastewater is one of the most common types of industrial wastewater. It mainly refers to wastewater discharged during farmland irrigation, livestock breeding, and other product production and processing. It includes farmland drainage, livestock breeding wastewater, and processing wastewater. The composition of agricultural wastewater is diverse and usually needs to be treated by wastewater treatment equipment before discharge.

[0004] Chinese patent application CN115353232A discloses a fertilizer production wastewater treatment device, including a base plate; a bottom box, positioned near the upper surface of the base plate, with a first annular plate fixedly connected to the lower end of the annular outer side of the bottom box, the lower end of the first annular plate being fixedly connected to the base plate via four annularly spaced pillars; an outer cylinder, positioned above the bottom box, with a second annular plate fixedly connected to the lower end of the annular outer side of the outer cylinder, the lower end of the second annular plate being fixedly connected to the first annular plate via four annularly spaced legs, the lower end of the outer cylinder communicating with the center of the upper surface of the bottom box via a second guide pipe; and an inner cylinder, positioned inside the outer cylinder, the upper end of the inner cylinder being fixedly connected to the center of the upper surface of the inner side of the outer cylinder, the lower end of the inner cylinder being... A first guide pipe is connected to the outer cylinder, and a water inlet pipe is connected to the upper end face of the outer cylinder near the outer edge of the inner cylinder; an alkali solution cylinder is symmetrically fixed to the upper end face of the outer cylinder, and a delivery pipe is connected to the lower end of the alkali solution cylinder, which passes through the outer cylinder to the inside of the inner cylinder; a stirring mechanism is set inside the inner cylinder to stir the wastewater and alkali solution entering the inner cylinder, including a drive shaft located at the center of the inner cylinder, a motor fixedly connected to the center of the upper end face of the outer cylinder, the output shaft of the motor passing through the inside of the inner cylinder and fixedly connected to the upper end of the drive shaft, three conical turntables are vertically and equidistantly fixedly connected to the drive shaft on the annular outer surface of the inner cylinder, and a funnel-shaped flow buffer plate is fixedly connected above each turntable on the inner wall of the inner cylinder, and a first scraper is symmetrically fixedly connected to the lower edge of each turntable.

[0005] In the aforementioned technology, the inlet pipe continuously feeds wastewater into the inner cylinder, and the funnel-shaped baffle reduces the downward flow speed of the wastewater. Simultaneously, the drive shaft rotates, causing the cam and impeller to rotate. The cam intermittently opens the sealing plug, allowing alkaline solution to enter the inner cylinder. The alkaline solution and wastewater mix and flow out through the leak. Meanwhile, the impeller rotates, drawing in and spraying out outside air. The sprayed air comes into contact with the falling wastewater and blows out the ammonia gas in the wastewater. The alkaline solution and fertilizer production wastewater cannot be fully mixed, which affects the efficiency of ammonia removal from the fertilizer production wastewater, resulting in poor wastewater treatment. Summary of the Invention

[0006] This invention provides an integrated wastewater treatment device, which aims to solve the technical problem in the prior art that the alkaline solution and fertilizer production wastewater cannot be fully mixed, which affects the stripping efficiency of ammonia in fertilizer production wastewater and results in poor wastewater treatment effect.

[0007] An integrated wastewater treatment device of the present invention includes a treatment device body, a shell disposed within the treatment device body, and an inner shell disposed within the shell. The shell is provided with an alkali inlet pipe, a water inlet pipe, and an air outlet pipe. It also includes an inner pipe, a first baffle, a moving mechanism, and a feeding control mechanism. The inner tube is rotatably disposed inside the inner shell. The inner tube can rotate under the drive of the rotation source. The inner tube is disposed along the central axis of the inner shell. The inner tube has an inlet at the top and an outlet at the bottom on its side wall. The first baffle is slidably disposed between the inner tube and the inner shell, and is used to divide the internal space of the shell into a stirring chamber communicating with the liquid inlet and a discharging chamber communicating with the liquid outlet; The moving mechanism is mounted on the housing and is used to drive the first baffle to move vertically and linearly. The feeding control mechanism is located in the inner shell. The feeding control mechanism is used to control the alkali inlet pipe to add one portion of alkali water each time, and to control the water inlet pipe to add one portion of fertilizer wastewater each time.

[0008] Beneficial effects: Through the feeding control mechanism, a certain amount of alkaline solution and fertilizer wastewater are first fed into the mixing chamber through the alkali inlet pipe and water inlet pipe, respectively. Then, the moving mechanism is activated, which moves the first baffle upward, pushing the mixture in the mixing chamber upward. The mixture flows upward from the inlet into the inner pipe and out through the outlet. The mixture flowing out of the inner pipe falls onto the bottom wall of the inner shell and flows out through the seepage hole, and is discharged to the subsequent stripping process where the ammonia gas in the mixture is stripped from the mixture. The quantitative ratio of alkaline solution and fertilizer wastewater ensures that the material ratio entering the mixing chamber each time is accurate and stable, facilitating subsequent mixing reactions. With the rotation of the inner pipe and the vertical reciprocating movement of the first baffle, the mixture in the mixing chamber can be disturbed and sheared in all directions, greatly improving the mixing uniformity of alkaline solution and fertilizer wastewater, so that the ammonia nitrogen in the wastewater is fully converted into a free state, thereby improving the efficiency of subsequent ammonia nitrogen stripping and significantly improving the overall wastewater treatment effect.

[0009] Preferably, the moving mechanism includes a first external thread provided on the side wall of the inner tube, a first internal thread that meshes with the first external thread on the first baffle, a first guide block that can guide the movement of the first baffle fixedly connected to the inner side wall of the inner shell, and a first guide groove provided on the first baffle that can cooperate with the first guide block.

[0010] Beneficial effects: When the inner tube rotates, the rotation of the inner tube drives the first baffle to slide along the first guide block. The upward and downward movement of the first baffle can be completed by the forward and reverse rotation of the inner tube. The structure is simple and the whole process does not require manual operation, saving manpower.

[0011] Preferably, the feeding control mechanism includes an alkali storage bin fixedly connected to the inner side of the top wall of the shell, the alkali storage bin being connected to the alkali inlet pipe, an alkali outlet pipe being fixedly connected to the bottom of the alkali storage bin, a first push plate being vertically slidably arranged inside the alkali storage bin, a first connecting rod being fixedly connected to the bottom of the first push plate, a third reset spring being arranged between the first push plate and the top of the alkali storage bin, a first flow hole being opened on the first push plate, and a second baffle being fixedly connected to the side wall of the first connecting rod.

[0012] Preferably, a water storage tank is provided on the outer side of the top wall of the shell, the water storage tank is connected to the water inlet pipe, and a water outlet pipe is fixedly connected to the bottom of the water storage tank.

[0013] Preferably, a second push plate is vertically slidably arranged inside the water storage tank, a second connecting rod is fixedly connected to the bottom of the second push plate, a fourth reset spring is fixedly connected between the second push plate and the top of the water storage tank, a second flow hole is opened on the second push plate, and a third baffle is fixedly connected to the side wall of the second connecting rod.

[0014] Beneficial effects: When the first baffle moves upward, the first baffle moves and pushes the second push plate, the second connecting rod and the third baffle to move and compress the fourth return spring. The third baffle moves and blocks the water outlet pipe. Then the first baffle continues to move upward and pushes the first push plate, the first connecting rod and the second baffle to move and compress the third return spring. The second baffle moves and blocks the alkali outlet pipe. After that, the first baffle moves to the highest position, the first push plate blocks the connection between the alkali inlet pipe and the alkali storage tank, and the second push plate blocks the connection between the water inlet pipe and the water storage tank.

[0015] Preferably, the inner tube has a second external thread on the side wall inside the feeding cavity, the second external thread having the opposite rotation direction to the first external thread, and a fourth baffle is slidably disposed between the inner tube and the inner shell, the fourth baffle having a second internal thread that meshes with the second external thread.

[0016] Preferably, the lower surface of the inner shell has a plurality of water seepage holes, and a second guide block is fixedly connected to the inner side wall of the inner shell to guide the movement of the fourth baffle. The fourth baffle has a second guide groove for the second guide block to slide. A top block is fixedly connected to the side wall of the fourth baffle near the bottom wall of the inner shell corresponding to the water seepage holes, and the top block can cooperate with the water seepage holes.

[0017] Beneficial effects: By setting a double external thread structure with opposite rotation directions on the inner tube, the first baffle and the fourth baffle can be driven to rise and fall in opposite directions vertically under the drive of the same rotation source. On the one hand, the volume of the stirring chamber and the fluid stirring are adjusted by the rise and fall of the first baffle. On the other hand, the top block is driven to move by the fourth baffle to control the opening and closing of the water seepage hole on the bottom wall of the inner shell, so as to realize the linkage of the stirring reaction, material feeding and drainage processes. The equipment has a high degree of integration, fewer driving components and strong operational stability.

[0018] Preferably, a fixed pipe is fixedly connected inside the inner tube.

[0019] Preferably, a plurality of stirring rods are fixedly connected to the side wall of the first baffle away from the fourth baffle.

[0020] Beneficial effects: By setting multiple sets of stirring rods on the side wall of the first baffle, the stirring rods can continuously cut and disturb the fluid in the mixing chamber as the first baffle rises and falls with the screw drive and rotates circumferentially under the restriction of the guide structure, thereby further enhancing the mixing effect, shortening the reaction mixing time, and effectively improving the processing efficiency of the equipment.

[0021] Preferably, a baffle plate is provided between the fixed pipe and the inner pipe, and the baffle plate abuts against the inner side wall of the inner pipe.

[0022] The beneficial effects of this invention are as follows: 1. In this invention, through the setting of the feeding control mechanism, a certain amount of alkaline solution and fertilizer wastewater are first controlled by the feeding control mechanism to enter the mixing chamber through the alkali inlet pipe and the water inlet pipe, respectively. Then, the moving mechanism is activated, which drives the first baffle to move upward and push the mixture in the mixing chamber upward. The mixture moves upward and enters the inner pipe through the liquid inlet and flows out through the liquid outlet. The mixture flowing out of the inner pipe falls on the bottom wall of the inner shell and flows out through the seepage hole, and is discharged to the subsequent stripping process. The ammonia gas in the mixture is stripped from the mixture. The quantitative ratio of alkaline solution and fertilizer wastewater ensures that the material ratio entering the mixing chamber each time is accurate and stable, which facilitates the subsequent mixing reaction. With the rotation of the inner pipe and the vertical reciprocating movement of the first baffle, the mixture in the mixing chamber can be disturbed and sheared in all directions, which greatly improves the mixing uniformity of alkaline solution and fertilizer wastewater, so that the ammonia nitrogen in the wastewater is fully converted into free state, thereby improving the subsequent ammonia nitrogen stripping efficiency and significantly improving the overall sewage treatment effect.

[0023] 2. In this invention, by setting a double external thread structure with opposite rotation directions on the inner tube, the first baffle and the fourth baffle can be driven to rise and fall in opposite directions vertically under the drive of the same rotation source. On the one hand, the volume of the stirring chamber and the fluid stirring are adjusted by the rise and fall of the first baffle. On the other hand, the top block is driven to move by the fourth baffle to control the opening and closing of the water seepage hole on the bottom wall of the inner shell, so as to realize the linkage of the stirring reaction, feeding and drainage processes. The equipment has a high degree of integration, fewer driving components and strong operational stability.

[0024] 3. In this invention, by setting multiple sets of stirring rods on the side wall of the first baffle, the stirring rods can continuously cut and disturb the fluid in the stirring chamber during the process of the first baffle rising and falling with the threaded transmission and rotating circumferentially by the guide structure, thereby further enhancing the mixing effect, shortening the reaction mixing time, and effectively improving the processing efficiency of the equipment.

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference Figures 1-8The present invention discloses an integrated wastewater treatment device, comprising a treatment device body and a housing 1 erected within the treatment device body. The housing 1 contains a first placement cavity 11, within which an inner shell 2 is disposed. The inner shell 2 contains a second placement cavity 21. The housing 1 is provided with an alkali inlet pipe 23 for receiving and conveying externally input alkaline solution, and the alkali inlet pipe 23 is connected to the second placement cavity 21. The housing 1 is also provided with a water inlet pipe 24, which is connected to the second placement cavity 21 and is used to receive and convey externally input fertilizer wastewater. The second placement cavity 21 contains an inner through pipe 3, which is located near the inlet pipe. One end of the alkali pipe 23 is provided with an inlet 31, and the end of the inner pipe 3 away from the alkali pipe 23 is provided with an outlet 32. A first baffle 4 is provided in the second placement cavity 21. The area above the first baffle 4 in the second placement cavity 21 is a stirring cavity 211. A moving mechanism 5 for driving the first baffle 4 to rotate, move up or down is provided in the second placement cavity 21. A feeding control mechanism 6 is provided on the shell 1. The feeding control mechanism 6 is used to control the alkali pipe 23 to input a portion of alkali solution into the second placement cavity 21 when the first baffle 4 completes one upward and downward movement, and to control the water inlet pipe 24 to input a portion of fertilizer wastewater into the second placement cavity 21.

[0036] When fertilizer wastewater needs to be treated, the moving mechanism 5 and the feeding control mechanism 6 are activated first. The moving mechanism 5 moves the first baffle 4 downward, and the feeding control mechanism 6 controls a portion of alkali solution and fertilizer wastewater to enter the second placement chamber 21 from the alkali inlet pipe 23 and the water inlet pipe 24, respectively. This small-batch input method allows the fertilizer wastewater and alkali solution to mix more thoroughly, facilitating the removal of ammonia from the mixture. Subsequently, the moving mechanism 5 moves the first baffle 4 upward, and the upward movement of the first baffle 4 pushes the mixture of alkali solution and fertilizer wastewater out from the inlet 31 through the outlet 32.

[0037] Reference Figures 5 to 8The moving mechanism 5 includes a support plate 51 fixedly sleeved on the circumferential sidewall at the middle position of the inner tube 3. A first return spring 52 is provided between the support plate 51 and the first baffle 4. A first guide block 22 is fixedly connected to the circumferential inner sidewall of the inner shell 2. A first guide groove 41 is provided on the circumferential sidewall of the first baffle 4 near the inner shell 2. A first positioning groove 42 is provided on the first baffle 4 corresponding to the first guide groove 41. A first stop block 53 is slidably disposed in the first positioning groove 42. A second stop block 53 is provided between the first stop block 53 and the sidewall of the first positioning groove 42 near the center of the inner shell 2. The return spring 54, the support plate 51 has a first annular groove 511 on the side wall near the first baffle 4, the first baffle 4 has a second stop block 55 fixedly connected to the side wall near the support plate 51 that can cooperate with the first annular groove 511, the inner tube 3 has a first external thread on the circumferential side wall, the lowest point of the first external thread is equal to the bottom wall height of the first guide block 22, the highest point of the first external thread is equal to the liquid inlet 31, the first baffle 4 has a first internal thread that cooperates with the first external thread, and the housing 1 is equipped with a rotation source 56 that can drive the inner tube 3 to rotate.

[0038] When the first baffle 4 needs to move upward, the rotation source 56 is first started. The drive shaft of the rotation source 56 rotates forward, driving the inner tube 3 to rotate. The rotation of the inner tube 3 drives the support plate 51 to rotate. The second stop block 55 and the first baffle 4 rotate under the friction of the first annular groove 511. Then the first guide groove 41 rotates to the first guide block 22. The first baffle 4 and the first stop block 53 move upward under the restoring force of the first return spring 52. The first guide groove 41 and the first guide block 22 cooperate. The first stop block 53 is blocked from moving towards the bottom of the first positioning groove 42 and the second return spring 54 is compressed. At the same time, the first external thread and the first internal thread begin to cooperate. After that, the drive shaft of the rotation source 56 continues to rotate forward and drives the inner tube 3 to rotate. The rotation of the inner tube 3 drives the first baffle 4 to move upward.

[0039] When the first baffle 4 needs to be moved down, the drive shaft of the rotation source 56 first reverses and drives the inner tube 3 and the support plate 51 to rotate. The rotation of the inner tube 3 drives the first baffle 4 to move down. The first baffle 4 moves down and compresses the first return spring 52. Then the first external thread and the first internal thread disengage. At the same time, the first stop block 53 moves away from the bottom wall of the first positioning groove 42 under the action of the restoring force of the second return spring 54. The second stop block 55 cooperates with the first annular groove 511. Then the drive shaft of the rotation source 56 continues to reverse and drives the support plate 51 to rotate. The second stop block 55 and the first baffle 4 rotate under the action of the friction force of the first annular groove 511.

[0040] Reference Figure 5 and Figure 6The feeding control mechanism 6 includes an alkali storage bin 61 fixedly connected to the inner wall of the housing 1. The alkali storage bin 61 is connected to the alkali inlet pipe 23. An alkali outlet pipe 611 is fixedly connected to the end of the alkali storage bin 61 away from the alkali inlet pipe 23. A third placement cavity is opened on the inner wall of the alkali storage bin 61 near the alkali inlet pipe 23. A first guide rod 62 is fixedly connected between the bottom wall of the third placement cavity and the side wall of the alkali storage bin 61 away from the alkali inlet pipe 23. A first push plate 63 is slidably sleeved on the first guide rod 62. A first push plate 63 is fixedly mounted on the side wall of the first push plate 63 away from the alkali inlet pipe 23. A first connecting rod 64 is fixedly connected to the first guide rod 62, which is located on the circumferential side wall between the bottom wall of the third placement cavity and the first push plate 63. A third return spring 65 is sleeved on the first push plate 63. A first flow passage hole 631 is opened on the first push plate 63. A first flow limiting block 612 is fixedly connected to the side wall of the alkali storage tank 61 away from the alkali inlet pipe 23, corresponding to the first flow passage hole 631. A second baffle 641 is fixedly sleeved on the circumferential side wall of the first connecting rod 64. When the first flow passage hole 631 begins to cooperate with the first flow limiting block 612, the alkali outlet pipe 611 is closed.

[0041] The distance between the second baffle 641 and the first push plate 63 is equal to the distance between the side wall of the alkali outlet pipe 611 away from the alkali storage tank 61 and the upper side wall of the first flow limiting block 612.

[0042] When the first baffle 4 moves upward, the first baffle 4 pushes the first push plate 63, the first connecting rod 64 and the second baffle 641 to move and compress the third reset spring 65. The second baffle 641 moves and blocks the alkali outlet pipe 611. Then the first baffle 4 moves to the highest position and the first push plate 63 blocks the connection between the alkali inlet pipe 23 and the alkali storage tank 61.

[0043] When the first baffle 4 moves down, the first push plate 63 moves down under the restoring force of the third reset spring 65, and the alkali inlet pipe 23 connects with the alkali storage tank 61. The alkali water in the alkali inlet pipe 23 enters the area above the first push plate 63 and flows down to the area below the first push plate 63 through the first flow passage 631. Then the first baffle 4 continues to move down, and the first flow passage 631 begins to cooperate with the first flow limiting block 612. The alkali water stops entering the area below the first push plate 63, and the alkali liquid below the first push plate 63 flows out into the second placement chamber 21.

[0044] Reference Figures 5-8A water storage tank 66 is fixedly connected to the inner wall of the housing 1. The water storage tank 66 is connected to the water inlet pipe 24. The end of the water storage tank 66 away from the water inlet pipe 24 is fixedly connected to the water outlet pipe 661. A fourth placement cavity is opened on the inner wall of the water storage tank 66 near the water inlet pipe 24. A second guide rod 67 is fixedly connected between the bottom wall of the fourth placement cavity and the side wall of the water storage tank 66 away from the water inlet pipe 24. A second push plate 68 is slidably sleeved on the second guide rod 67. The side wall of the second push plate 68 away from the water inlet pipe 24 is fixedly connected to... There is a second connecting rod 69, a second guide rod 67 located on the circumferential side wall between the bottom wall of the fourth placement cavity and the second push plate 68, a fourth reset spring 610 is sleeved on the second push plate 68, a second flow passage hole 681 is opened on the second push plate 68, a second flow limiting block is fixedly connected to the side wall of the water storage tank 66 away from the water inlet pipe 24 corresponding to the second flow passage hole 681, and a third baffle 691 is fixedly sleeved on the circumferential side wall of the second connecting rod 69. The water outlet pipe 661 is closed when the second flow passage hole 681 begins to cooperate with the second flow limiting block.

[0045] When the first baffle 4 moves upward, the first baffle 4 moves and pushes the second push plate 68, the second connecting rod 69 and the third baffle 691 to move and compress the fourth return spring 610. The third baffle 691 moves and blocks the water outlet pipe 661. Then the first baffle 4 moves to the highest position and the second push plate 68 blocks the water inlet pipe 24 from connecting with the water storage tank 66.

[0046] When the first baffle 4 moves down, the second push plate 68 moves down under the restoring force of the fourth reset spring 610, and the water inlet pipe 24 and the water storage tank 66 are connected. The fertilizer wastewater in the water inlet pipe 24 enters the area above the second push plate 68 and enters the area below the second push plate 68 through the second flow hole 681. Then the first baffle 4 continues to move down, and the second flow limiting block cooperates with the second flow hole 681. The fertilizer wastewater between the second push plate 68 and the third baffle 691 is metered, and the fertilizer wastewater below the second push plate 68 flows out.

[0047] Reference Figures 5-8A fourth baffle 7 is provided on the side of the support plate 51 away from the first baffle 4. A fifth return spring 8 is provided between the fourth baffle 7 and the support plate 51. A second guide block 25 is symmetrically arranged on the inner side wall of the inner shell 2 about the support plate 51. A second guide groove 71 is provided on the inner side wall of the fourth baffle 7 near the inner shell 2. A second positioning groove 72 is provided on the fourth baffle 7 corresponding to the second guide groove 71. A third stop 73 is slidably arranged in the second positioning groove 72. The third stop 73 and the second positioning groove 72 are connected. A sixth return spring 74 is provided between the side walls near the center of the inner shell 2. A second annular groove 512 is provided on the side wall of the support plate 51 near the fourth baffle 7. A fourth stop block 75 that can cooperate with the second annular groove 512 is fixedly connected on the side wall of the fourth baffle 7 near the support plate 51. A second external thread is provided on the side wall of the inner tube 3 corresponding to the second guide block 25. A second internal thread that cooperates with the second external thread is provided on the fourth baffle 7. Multiple seepage holes 26 are provided on the side wall of the inner shell 2 away from the alkali inlet pipe 23.

[0048] When the drive shaft of the rotation source 56 rotates forward and drives the inner tube 3 to rotate, the rotation of the inner tube 3 drives the support plate 51 to rotate. The fourth stop 75 and the fourth baffle 7 rotate under the action of the friction of the second ring groove 512. Then the second guide groove 71 rotates to the second guide block 25. The fourth baffle 7 and the third stop 73 move down under the action of the restoring force of the fifth return spring 8. The second guide groove 71 and the second guide block 25 cooperate. The third stop 73 is blocked from moving towards the bottom of the second positioning groove 72 and the sixth return spring 74 is compressed. At the same time, the second external thread and the second internal thread begin to cooperate. After that, the drive shaft of the rotation source 56 continues to rotate forward and drives the inner tube 3 to rotate. The rotation of the inner tube 3 drives the fourth baffle 7 to move down.

[0049] When the fourth baffle 7 needs to move upward, the drive shaft of the rotation source 56 first reverses and drives the inner tube 3 and the support plate 51 to rotate. The rotation of the inner tube 3 drives the fourth baffle 7 to move upward. The fourth baffle 7 moves upward and compresses the fifth return spring 8. Then the second external thread and the second internal thread disengage. At the same time, the third stop 73 moves away from the bottom wall of the second positioning groove 72 under the restoring force of the sixth return spring 74. The fourth stop 75 engages with the second annular groove 512. Then the drive shaft of the rotation source 56 continues to reverse and drives the support plate 51 to rotate. The fourth stop 75 and the fourth baffle 7 rotate under the friction of the second annular groove 512.

[0050] Reference Figure 5 and Figure 7 A fixed pipe 33 is fixedly connected inside the inner pipe 3. A baffle plate is provided between the fixed pipe 33 and the inner pipe 3, and the baffle plate abuts against the inner side wall of the inner pipe 3. Multiple stirring rods 43 are fixedly connected on the side wall of the first baffle plate 4 away from the fourth baffle plate 7, and the stirring rods 43 are arranged to avoid the alkali outlet pipe 611 and the water outlet pipe 661.

[0051] When the first baffle 4 rotates, it drives multiple stirring rods 43 to rotate and stir the alkaline solution and fertilizer wastewater. When the first baffle 4 pushes the mixture upward, the mixture can collide with the stirring rods 43, thereby improving the mixing effect of the alkaline solution and fertilizer wastewater. This helps to ensure that the mixed fertilizer wastewater reaches the preset pH value, making it convenient for the treatment of fertilizer wastewater.

[0052] Reference Figure 6 and Figure 7 On the side wall of the fourth baffle 7 away from the first baffle 4, there are multiple top blocks 76 corresponding to the seepage holes 26, and the top blocks 76 can enter the seepage holes 26.

[0053] The implementation principle of the integrated sewage treatment equipment of the present invention is as follows: Before the equipment is put into operation, alkali solution is added to the alkali storage tank 61 through the alkali inlet pipe 23, and fertilizer wastewater is added to the water storage tank 66 through the water inlet pipe 24; In the initial state, the third return spring 65 and the fourth return spring 610 are in the extended state, the second baffle 641 blocks the alkali outlet pipe 611, and the third baffle 691 blocks the water outlet pipe 661; the first baffle 4 is located in the lower stroke position, the fourth baffle 7 is located in the upper stroke position, and the top block 76 is disengaged from the seepage hole 26; When fertilizer wastewater and alkali need to be mixed, the rotation source 56 is first started. The drive shaft of the rotation source 56 reverses, causing the inner pipe 3 and the support plate 51 to rotate. The rotation of the inner pipe 3 causes the first baffle 4 to move down and the fourth baffle 7 to move up. When the first baffle 4 moves down, the first push plate 63 moves down under the restoring force of the third reset spring 65. The alkali inlet pipe 23 is connected to the alkali storage tank 61. The alkali water in the alkali inlet pipe 23 enters above the first push plate 63 and flows down through the first flow hole 631 to below the first push plate 63. As the second push plate 68 moves, it moves downward under the restoring force of the fourth reset spring 610. The water inlet pipe 24 and the water storage tank 66 are connected. The fertilizer wastewater in the water inlet pipe 24 enters the area above the second push plate 68 and enters the area below the second push plate 68 through the second flow hole 681. Then the first baffle 4 continues to move downward. The first flow hole 631 begins to cooperate with the first flow limiting block 612. The alkaline solution between the first push plate 63 and the second baffle 641 is metered. The alkaline outlet pipe 611 is connected to the second placement cavity 21. The alkaline solution below the first push plate 63 flows out. Then, the second flow-limiting block cooperates with the second flow-through hole 681, and the fertilizer wastewater between the second push plate 68 and the third baffle 691 is metered. The fertilizer wastewater below the second push plate 68 flows out. Then, the first baffle 4 continues to move down and compresses the first return spring 52. Subsequently, the first external thread and the first internal thread disengage. At the same time, the first stop block 53 moves away from the bottom wall of the first positioning groove 42 under the restoring force of the second return spring 54. The second stop block 55 cooperates with the first annular groove 511. Then, the drive shaft of the rotation source 56 continues to reverse and drives the support plate 51 to rotate. The second stop block 55 and The first baffle 4 rotates under the friction of the first annular groove 511; when the first baffle 4 moves down, the fourth baffle 7 moves up and compresses the fifth return spring 8. Then the second external thread and the second internal thread disengage. At the same time, the third stop 73 moves away from the bottom wall of the second positioning groove 72 under the restoring force of the sixth return spring 74. The fourth stop 75 engages with the second annular groove 512. Then the drive shaft of the rotation source 56 continues to reverse and drives the support plate 51 to rotate. The fourth stop 75 and the fourth baffle 7 rotate under the friction of the second annular groove 512.

[0054] When fertilizer wastewater needs to be treated, the drive shaft of the rotation source 56 first rotates clockwise. The rotation of the drive shaft of the rotation source 56 drives the support plate 51 and the inner tube 3 to rotate. The rotation of the support plate 51 drives the first baffle 4 and the fourth baffle 7 to rotate. Then, the first guide groove 41 on the first baffle 4 rotates to the first guide block 22. The first baffle 4 moves upward under the restoring force of the first return spring 52. The first guide groove 41 and the first guide block 22 cooperate. The first stop 53 moves towards the bottom wall of the first positioning groove 42 and compresses the second return spring 54. The first external thread and the first internal thread begin to cooperate. At the same time, the second guide groove 71 on the fourth baffle 7 rotates to the second guide block 25. The fourth baffle 7 and the third stop 73 move downward under the restoring force of the fifth return spring 8. The second guide groove 71 and the second guide block 25 cooperate. The third stop 73 is blocked from moving towards the bottom of the second positioning groove 72 and the sixth return spring 8 is released. Spring 74 is compressed, and simultaneously the second external thread and the second internal thread begin to engage. Then, the drive shaft of the rotation source 56 continues to rotate clockwise, driving the inner tube 3 to rotate. The rotation of the inner tube 3 causes the first baffle 4 to move upward and the fourth baffle 7 to move downward. The movement of the first baffle 4 pushes the second push plate 68, the second connecting rod 69, and the third baffle 691 to move, compressing the fourth return spring 610. The third baffle 691 moves and blocks the outlet pipe 661. Subsequently, the first baffle 4 continues to move upward and pushes the second push plate 68, the second connecting rod 69, and the third baffle 691 to move, compressing the fourth return spring 610. The push plate 63, the first connecting rod 64, and the second baffle 641 move and compress the third return spring 65. The second baffle 641 moves and blocks the alkali outlet pipe 611. Then the first baffle 4 moves to the highest position. The first push plate 63 blocks the connection between the alkali inlet pipe 23 and the alkali storage tank 61. The second push plate 68 blocks the connection between the water inlet pipe 24 and the water storage tank 66. When the first baffle 4 moves upward, it pushes the mixed fertilizer wastewater from the liquid inlet 31 through the liquid outlet 32 ​​and onto the bottom wall of the inner shell 2.

[0055] After mixing, the inner tube 3 continues to rotate in the reverse direction, the first baffle 4 continues to descend, the fourth baffle 7 rises synchronously, and the top block 76 gradually detaches from the seepage hole 26; the mixed liquid in the stirring chamber 211 enters the inner tube 3 through the liquid inlet 31, then flows into the feeding chamber 212 through the liquid outlet 32, and is finally discharged through the seepage hole 26 to the subsequent stripping process. The free ammonia nitrogen is stripped and discharged and recovered through the gas outlet pipe. After completing one treatment cycle, the rotating source 56 rotates forward again, driving each component to reset and enter the next round of feeding, mixing, and drainage cycle.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
