Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a method and apparatus for treating poultry manure wastewater. Background Technology

[0002] The main methods for treating poultry manure wastewater include: Septic tanks: These treat organic waste through direct contact between anaerobic bacteria and precipitated sludge. Biogas purification ponds: These multi-stage baffled wastewater treatment devices, combining water-pressure biogas digesters, anaerobic filters, and facultative ponds, effectively remove solid particles and organic matter from wastewater while killing pathogens. Natural treatment technologies: These include constructed wetlands, land treatment, and stabilization ponds, utilizing natural physical, chemical, and biological processes to purify wastewater. Dry manure cleaning: This involves collecting all or most of the solid manure from the floor of livestock sheds manually or mechanically. Residual manure on the floor is flushed with a small amount of water, separating solid and liquid waste. Water-flushing manure: A certain amount of water is injected into the manure drainage ditch in the pigsty, and manure, flushing water, and feeding management water are discharged together. After a certain period of storage, the manure is discharged. However, this method consumes a large amount of water and may produce a large amount of harmful gases. Water flushing manure process: This removes manure and urine from the livestock shed by flushing, maintaining a hygienic environment. However, this method consumes a large amount of water, and the concentration of pollutants in the treated wastewater remains high.

[0003] Existing technologies for treating poultry manure wastewater mostly involve generating biogas through biogas purification ponds, or compressing and dehydrating the manure to make fertilizer. In this process, conventional wastewater treatment uses structures like sieves to screen the manure and wastewater, but preventing clogging of the sieves and collecting and sorting the manure is quite difficult, and manual cleaning can affect the efficiency of the device in treating wastewater. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a method and apparatus for treating poultry manure wastewater to solve the problems mentioned in the background. The present invention features a novel structure. A rotating component drives two push plates inside the collection tank to rotate in a ring, pushing the wastewater containing manure and preventing blockage of the drain. The wastewater enters the filter layer and is compressed by the compression component before entering the anaerobic tank for further treatment. After the manure is dehydrated and the connecting layer is dried in the drying position, it is flipped to send the manure out. Subsequently, the screen plate is washed and rinsed for reuse. During this process, four sets of screen plates and connecting layers are provided for replacement, avoiding interruption of the equipment cleaning process and simultaneously preventing blockage and facilitating the discharge of manure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a poultry manure wastewater treatment device, comprising a water collection tank, a filter layer fixed at the bottom of the water collection tank, and a notch larger than the inner diameter of the filter layer at the center of the water collection tank.

[0007] Furthermore, the compression assembly also includes a first electric push rod, with the first electric push rod fixed on both sides of the slide rod on the fixing plate, and the extended end of the first electric push rod is fixedly connected to the conical disc, with the top of the conical disc making contact with the top of the sieve plate.

[0008] Furthermore, sealing rings are slidably fitted on the upper and lower outer walls of the filter layer at the insertion position of the connecting layer, and second electric push rods are fixed on the corresponding upper and lower outer walls of the filter layer, with the extended ends of the second electric push rods fixedly connected to the sealing rings.

[0009] Furthermore, an odor treatment box is fixed to the upper end of the next set of connecting layers at the bottom of the water collection tank in a counterclockwise direction, and an exhaust pipe is provided on the top of the odor treatment box. A drying layer is provided at the bottom of the odor treatment box, and a drying fan is built into the drying layer. A vertical frame is fixed to the outside of the drying layer and the odor treatment box, and the connecting layer can be inserted between the odor treatment box and the drying layer.

[0010] Furthermore, a cleaning frame is provided at the bottom of another set of connecting layers symmetrical to the drying position at the bottom of the water collection tank. The cleaning frame is connected to the lower end of the filter layer through a pipe, and a return pipe is provided on one side of the cleaning frame.

A cleaning plate is installed inside the cleaning frame, and nozzles are equidistantly arranged on the surface of the cleaning plate.

[0011] Furthermore, a rotating plate shaft is provided between the connecting circular plate at the bottom of the second motor and the four connecting layers.

[0012] Furthermore, an L-shaped connecting bracket is fixed to one side of the mounting plate, and the other end of the connecting bracket is fixedly connected to the bottom of the sealing plate.

[0013] A method for treating poultry manure wastewater, the wastewater treatment method comprising the following steps:

[0014] 1) Treatment of manure and sewage: After adding flocculant to poultry manure wastewater, it is introduced into the collection tank. The first motor drives the gear to rotate. The gear meshes with the gear ring and drives the two push plates in the collection tank to rotate in a cycle. This scrapes and cleans the inside of the collection tank, preventing the leakage channel from getting blocked and avoiding the accumulation of manure at the bottom. The first electric push rod drives the cone disc to move down along the slide rod, compressing and dewatering the manure on the surface of the screen plate. The sewage is sent into the anaerobic tank through the screen plate and the filter layer. After being treated by anaerobic bacteria aeration, it is discharged for the next process treatment.

[0015] 2) Switching between the connecting layer and the sieve plate: The connecting layer is switched by the rotation of the second motor and passes through the drying position, the delivery position and the cleaning position respectively. The connecting layer enters between the odor treatment box and the drying layer. It is dried by the drying fan inside the drying layer. The original odor of the feces enters the odor treatment box for treatment.

[0016] 3) Discharge of feces: The third electric push rod drives the rotating plate of the rotating plate frame to insert into the gap of the rotating plate shaft. Then, the drive motor on the back of the mounting plate controls the rotation of the rotating plate frame, which drives the connecting layer and the screen plate to flip and put the compressed and dried feces into the plate. When the mounting plate descends through the connection of the connecting frame, the sealing plate will also open the outlet of the water collection tank at the same time. During the rotation of the push plate, the remaining impurities in the water collection tank that cannot pass through the trough can be pushed out from the outlet. Two collection frames or conveying platforms are set at the bottom of the outlet and the bottom of the delivery position to transport the feces for the preparation of organic fertilizer.

[0017] 4) Cleaning of the screen plate: The cleaning water in the cleaning frame is the sewage after the filter layer has been screened by the screen plate. It is pumped into the cleaning frame and then sprayed onto the surface of the screen plate through the cleaning plate and nozzle by the conveying pump. The screen plate at this position is the original surface of the compressed feces. The residual feces on the screen plate are cleaned off. Then the sewage is returned to the water collection tank through the return pipe for further circulation treatment.

[0018] Furthermore, regarding the characteristics of the conical disc in step 1, the bottom plane radius of the conical disc is the same as that of the sieve plate. Since the inner radius of the water collection tank is larger than the radius of the filter layer, the water delivery will not be affected when the conical disc moves to the inner circle of the water collection tank.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention dries the feces by blowing air through a drying fan inside the drying layer. The original odor of the feces enters the odor treatment box for treatment. A third electric push rod drives the rotating plate of the rotating plate frame to insert into the gap of the rotating plate shaft. Then, the drive motor on the back of the mounting plate controls the rotation of the rotating plate frame, causing the connecting layer and the screen plate to flip and put the compressed and dried feces into the container. Through the connection of the connecting frame, when the mounting plate descends, the sealing plate will also open the outlet of the water collection tank simultaneously. During the rotation of the push plate, the remaining impurities in the water collection tank that cannot pass through the trough can be pushed out from the outlet. Two collection frames or conveying platforms are set at the bottom of the outlet and the bottom of the delivery position to transport the feces for the preparation of organic fertilizer.

[0021] 2. The cleaning water in the cleaning frame of the present invention is the wastewater after the filter layer has been screened by the sieve plate. It is pumped into the cleaning frame and then sprayed onto the surface of the sieve plate by the conveying pump through the cleaning disc and the nozzle. The sieve plate at this position is the original surface of the compressed feces. The residual feces on the sieve plate are cleaned off. Then the wastewater is returned to the water collection tank through the return pipe for further circulation and treatment, which saves water resources and keeps the sieve plate clean.

[0022] 3. In this invention, the second electric push rod drives two sealing plates to seal the upper and lower edges of the connecting layer to prevent water leakage. The first electric push rod drives the cone disc to move downward along the slide rod to compress and dehydrate the feces on the surface of the sieve plate. The bottom plane radius of the cone disc is the same as that of the sieve plate. Because the inner radius of the water collection tank is larger than the radius of the filter layer, the water delivery will not be affected when the cone disc moves to the inner circle of the water collection tank.

[0023] 4. In this invention, the first motor drives the gear to rotate, and the gear meshes with the gear ring to drive the two push plates inside the water collection tank to rotate in a cycle, scraping and cleaning the inside wall of the water collection tank, preventing the leakage channel from getting blocked and avoiding the accumulation of feces at the bottom.

[0024] 5. Compared with the prior art, the present invention uses a rotating component to drive two push plates in the water collection tank to rotate in a ring, pushing the wastewater containing feces to avoid clogging the drain. The wastewater enters the filter layer and is compressed by the compression component. The wastewater then enters the anaerobic tank for further treatment. The feces are dehydrated and rotate together with the connecting layer to enter the drying position. After drying, the feces are turned over and sent out. The screen plate is then cleaned and rinsed for reuse. During this process, four sets of screen plates and connecting layers are provided for replacement, avoiding interruption of the equipment cleaning process. This also prevents clogging and facilitates the discharge of feces. Attached Figure Description

[0037] 1) Treatment of manure and sewage: After adding flocculant to poultry manure wastewater, it is introduced into the collection tank. The first motor drives the gear to rotate. The gear meshes with the gear ring and drives the two push plates in the collection tank to rotate in a cycle. This scrapes and cleans the inside of the collection tank, preventing the leakage channel from getting blocked and avoiding the accumulation of manure at the bottom. The first electric push rod drives the cone disc to move down along the slide rod, compressing and dewatering the manure on the surface of the screen plate. The sewage is sent into the anaerobic tank through the screen plate and the filter layer. After being treated by anaerobic bacteria aeration, it is discharged for the next process treatment.

[0038] 2) Switching between the connecting layer and the sieve plate: The connecting layer is switched by the rotation of the second motor and passes through the drying position, the delivery position and the cleaning position respectively. The connecting layer enters between the odor treatment box and the drying layer. It is dried by the drying fan inside the drying layer. The original odor of the feces enters the odor treatment box for treatment.

[0039] 3) Discharge of feces: The third electric push rod drives the rotating plate of the rotating plate frame to insert into the gap of the rotating plate shaft. Then, the drive motor on the back of the mounting plate controls the rotation of the rotating plate frame, which drives the connecting layer and the screen plate to flip and put the compressed and dried feces into the plate. When the mounting plate descends through the connection of the connecting frame, the sealing plate will also open the outlet of the water collection tank at the same time. During the rotation of the push plate, the remaining impurities in the water collection tank that cannot pass through the trough can be pushed out from the outlet. Two collection frames or conveying platforms are set at the bottom of the outlet and the bottom of the delivery position to transport the feces for the preparation of organic fertilizer.

[0040] 4) Cleaning of the screen plate: The cleaning water in the cleaning frame is the sewage after the filter layer has been screened by the screen plate. It is pumped into the cleaning frame and then sprayed onto the surface of the screen plate through the cleaning plate and nozzle by the conveying pump. The screen plate at this position is the original surface of the compressed feces. The residual feces on the screen plate are cleaned off. Then the sewage is returned to the water collection tank through the return pipe for further circulation treatment.

[0041] A poultry manure wastewater treatment device includes a water collection tank 1, a filter layer 7 fixed to the bottom of the water collection tank 1, and a notch larger than the inner diameter of the filter layer 7 at the center of the water collection tank 1. A compression assembly 4 is provided at the center of the water collection tank 1 and the filter layer 7. The compression assembly 4 includes a fixing plate 41, the fixing plate 41 is fixed to the inner ring of the water collection tank 1, and a sliding rod 42 is fixed to the bottom center of the fixing plate 41. A conical disc 44 is slidably sleeved on the surface of the sliding rod 42. The top of the water collection tank 1 is equipped with a rotating assembly 3, which includes a connecting plate 34. The sliding rod 42 passes through the top of the fixed plate 41 and is rotatably mounted on the connecting plate 34 via bearings. Push plates 35 are fixed at the bottom of both ends of the connecting plate 34. The push plates 35 slide in contact with the inner wall of the outer ring and the outer wall of the inner ring of the water collection tank 1. The inner ring surface of the water collection tank 1 is provided with equally spaced grooves 11. The lower end of the water collection tank 1 is provided with four sets of connecting layers 2, and double-sided sieve plates 21 are fixed inside the connecting layers 2. The connecting layer 2 can be alternately inserted into the filter layer 7. An anaerobic tank 6 is provided on one side of the bottom of the water collection tank 1, and the bottom of the filter layer 7 is connected to the anaerobic tank 6 through a pipe. An outlet is opened on one side of the bottom of the water collection tank 1, and a sealing plate 95 is sealed on the surface of the outlet of the water collection tank 1. A second motor 10 is fixed at the center of the four sets of connecting layers 2 at the bottom of the water collection tank 1, and the output end of the second motor 10 is fixedly connected to the connecting circular plate of the four sets of connecting layers 2. When using the device, poultry manure wastewater is added to flocculant and then introduced into the water collection tank 1. Through the cooperation of the rotating component 3 and the compression component 4, the sewage is sent into the anaerobic tank 6 through the screen plate 21 and the filter layer 7. After being treated by anaerobic bacteria aeration, it is discharged for the next process treatment. The connecting layer 2 is switched by the rotation of the second motor 10 and passes through the drying position, the discharge position and the cleaning position respectively. After drying the manure, it is sent out, and the surface of the screen plate 21 is cleaned and replaced, maintaining efficient sewage treatment and manure collection.

[0042] In this embodiment, the rotating assembly 3 further includes a gear ring 33. The top of the water collection tank 1 is provided with an annular groove 12, and the gear ring 33 is slidably installed on the annular groove 12. The bottom of the gear ring 33 is fixed with a circular ring 331 that slides along the annular groove 12, and both ends of the connecting plate 34 are fixed to the gear ring 33. A first motor 31 is fixed on one side of the outer wall of the water collection tank 1, and a gear 32 is fixed at the output end of the first motor 31. The gear 32 meshes with the gear ring 33. The first motor 31 drives the gear 32 to rotate. The meshing of the gear 32 with the gear ring 33 drives the two push plates 35 inside the water collection tank 1 to rotate cyclically, scraping and cleaning the inside of the water collection tank 1, preventing the leakage groove 11 from becoming blocked, and avoiding the accumulation of feces at the bottom.

[0043] In this embodiment, the compression assembly 4 further includes a first electric push rod 43. The first electric push rod 43 is fixed on both sides of the slide rod 42 on the fixing plate 41, and the extended end of the first electric push rod 43 is fixedly connected to the conical disk 44.

The extended end is fixedly connected to the sealing ring 71. After the connecting layer 2 is inserted into the filter layer 7, the second electric push rod 72 drives the two sealing plates 95 to seal the upper and lower edges of the connecting layer 2 to prevent water leakage. The first electric push rod 43 drives the cone disc 44 to move downward along the slide rod 42 to compress and dehydrate the feces on the surface of the sieve plate 21. The bottom plane radius of the cone disc 44 is the same as that of the sieve plate 21. Because the inner circle radius of the water collection tank 1 is larger than the radius of the filter layer 7, the water delivery will not be affected when the cone disc 44 moves to the inner circle of the water collection tank 1.

[0044] In this embodiment, an odor treatment box 8 is fixed to the upper end of the next set of connecting layers 2 in a counterclockwise direction at the bottom of the water collection tank 1, and an exhaust pipe 81 is provided on the top of the odor treatment box 8.

The connecting layer 2 enters between the odor treatment box 8 and the drying layer 83, and is dried by the drying fan inside the drying layer 83. The original odor of the feces enters the odor treatment box 8 for treatment, and is then discharged through the exhaust pipe 81. This odor treatment box 8 is the same as the odor treatment method in the prior art of sewage treatment, and can be treated by activated carbon adsorption.

The top of the return pipe 51 corresponds to the top of the water collection tank 1. A cleaning plate 52 is installed inside the cleaning frame 5, and nozzles are equidistantly arranged on the surface of the cleaning plate 52. The cleaning water in the cleaning frame 5 is the sewage after the filter layer 7 has been screened by the sieve plate 21. It is pumped into the cleaning frame 5 and then sprayed onto the surface of the sieve plate 21 through the cleaning plate 52 and the nozzles by the conveying pump. The sieve plate 21 at this position is the original surface of the compressed feces. The residual feces on the sieve plate 21 are cleaned off. Then the sewage is returned to the water collection tank 1 through the return pipe 51 for further circulation and treatment, saving water resources and keeping the sieve plate 21 clean.

[0046] In this embodiment, a rotating shaft 93 is provided between the connecting circular plate at the bottom of the second motor 10 and the four connecting layers 2. One end of the rotating shaft 93 is rotatably connected to the connecting circular plate via a bearing, and the other end of the rotating shaft 93 is fixed to the connecting layer 2. A third electric push rod 9 is fixed at the position of the rotating shaft 93 on the inner side of the connecting layer 2 at the bottom of the water collection tank 1 corresponding to the outward-facing end. A mounting plate 91 is fixed to the extended end of the third electric push rod 9. A rotating plate frame 92 is rotatably mounted on the front of the mounting plate 91 via a bearing. A drive motor for connecting the rotating plate frame 92 is installed on the back of the mounting plate 91. The rotating plate frame 92 can be inserted into the gap of the rotating plate shaft 93. An L-shaped connecting frame 94 is fixed on one side of the mounting plate 91, and the other end of the connecting frame 94 is fixedly connected to the bottom of the sealing plate 95. The connecting layer 2 facing outward, that is, the connecting layer 2 between the drying position, the washing position and the filtering position, serves as the station for discharging the compressed feces. The position of the rotating plate frame 92 corresponds exactly to the rotating plate shaft 93 at this position. (The structure of the rotating plate frame 92 and the rotating plate shaft 93 is as follows...) Figure 9 As shown, it consists of multiple vertical plates equidistantly fixed on a shaft, with gaps between adjacent vertical plates. One end of the connecting layer 2 is fixed to the rotating shaft 93, and the other end is rotatably connected to the connecting circular plate at the bottom of the second motor 10 via a bearing. According to... Figure 9The structure shown, along with the positions of the rotating plate frame 92 and the rotating plate shaft 93, allows the vertical plates on the rotating plate frame 92 to be inserted between the two vertical plates on the rotating plate shaft 93 when the mounting plate 91 is pushed downwards by the third electric push rod 9. The rotating plate frame 92 rotates, driving the rotating plate shaft 93, and the connecting layer 2 can be flipped by alternating insertion. The third electric push rod 9 drives the rotating plate of the rotating plate frame 92 to be inserted into the gap of the rotating plate shaft 93. Then, the rotating plate frame 92 is controlled to rotate by the drive motor on the back of the mounting plate 91, causing the connecting layer 2 and the screen plate 21 to flip, allowing the compressed and dried manure to be deposited. Through the connection of the connecting frame 94, when the mounting plate 91 descends, the sealing plate 95 will also open the outlet of the water collection tank 1 simultaneously. During the rotation of the push plate 35, impurities remaining in the water collection tank 1 that cannot pass through the trough 11 can be pushed out from the outlet. Two collection frames or conveying platforms are set at the bottom of the outlet and the bottom of the delivery position to transport the manure for the preparation of organic fertilizer.

[0047] When using the device, poultry manure wastewater is added to a flocculant and then introduced into the collection tank 1. The first motor 31 drives the gear 32 to rotate. The gear 32 meshes with the gear ring 33, causing the two push plates 35 inside the collection tank 1 to rotate in a cycle, scraping and cleaning the inner wall of the collection tank 1 to prevent blockage of the trough 11 and avoid manure sedimentation at the bottom. The first electric push rod 43 drives the cone disc 44 to move downward along the slide rod 42, compressing and dewatering the manure on the surface of the screen plate 21. The wastewater is sent into the anaerobic tank 6 through the screen plate 21 and the filter layer 7. After being treated by anaerobic bacteria aeration, it is discharged for the next process. The connecting layer 2 is switched by the rotation of the second motor 10, passing through the drying position, the discharge position, and the cleaning position respectively. It is dried by the drying fan inside the drying layer 83. The original odor of the manure enters the odor treatment box 8 for treatment, and then is discharged through the exhaust pipe 81. The third electric push rod 9 drives the rotating plate of the rotating plate frame 92 to insert into the gap of the rotating plate shaft 93, and then through the back of the mounting plate 91 The drive motor controls the rotating plate frame 92 to rotate, causing the connecting layer 2 and the screen plate 21 to flip, and the compressed and dried manure is put in. When the mounting plate 91 is lowered through the connection of the connecting frame 94, the sealing plate 95 will also open the outlet of the water collection tank 1 at the same time. During the rotation, the push plate 35 can push out the impurities in the water collection tank 1 that cannot pass through the trough 11 from the outlet. Two collection frames or conveying platforms are set at the bottom of the outlet and the bottom of the delivery position to transport the manure for the preparation of organic fertilizer. The cleaning water in the cleaning frame 5 is the sewage after the filter layer 7 has been screened by the screen plate 21. It is pumped into the cleaning frame 5 and then sprayed onto the surface of the screen plate 21 through the cleaning plate 52 and the nozzle by the conveying pump. The screen plate 21 at this position is the original surface of the compressed manure. The residual manure on the screen plate 21 is cleaned off. Then the sewage is returned to the water collection tank 1 through the return pipe 51 for further circulation and treatment, saving water resources and keeping the screen plate 21 clean, maintaining efficient sewage treatment and manure collection.
