Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a method and a device for treating poultry excrement sewage. Background Art

[0002] The methods for treating poultry manure sewage mainly include the following: Septic tank: anaerobic bacteria decompose sewage and directly contact with sediment sludge to treat organic waste. Biogas purification tank: a multi-stage baffled sewage treatment device that combines hydraulic biogas tanks, anaerobic filters and facultative ponds can effectively remove solid particles and organic matter in sewage and kill pathogens at the same time. Natural treatment technology: such as artificial wetlands, land treatment, stabilization ponds, etc. These technologies use physical, chemical and biological processes in nature to purify sewage. Dry manure cleaning: all or most of the solid manure is collected from the ground of livestock and poultry houses by manual or mechanical means, and the residual manure and urine on the ground are washed with a small amount of water to achieve the separation of solid and liquid waste. Water-soaked manure: a certain amount of water is injected into the manure ditch in the pig house, and the manure, urine, flushing and feeding management water are discharged together, and discharged after a certain period of storage, but this method consumes a lot of water and may produce a large amount of harmful gases. Water-flushing manure process: manure and urine in the livestock house are removed by water flushing to maintain the environmental hygiene of the livestock house, but the water consumption is large and the concentration of pollutants in the treated sewage is still high.

[0003] In the existing technology for treating poultry manure sewage, biogas is mostly produced by biogas purification tanks, and the manure is compressed and dehydrated to make fertilizer. In this step, because conventional sewage treatment uses a structure such as a sieve plate to screen the manure and sewage, and the sieve plate is difficult to prevent blocking and the manure is collected and sorted, manual cleaning will affect the efficiency of the sewage treatment device.

The sewage enters the filter layer and is compressed by the compression component. The sewage enters the anaerobic tank for subsequent treatment. After the feces are dehydrated and the connecting layer is rotated into the drying position for drying, the feces is flipped to send out, and then the sieve plate is cleaned and rinsed and returned for use. In this process, the sieve plate and the connecting layer are provided with four groups that can be replaced and used to avoid interrupting the time process of equipment cleaning, while preventing blockage and facilitating the delivery of feces.

[0014] 1) Treatment of feces and sewage: After adding flocculants to poultry feces wastewater, it is passed into the water collection tank. The first motor drives the gear to rotate. The gear meshes with the gear ring to drive the two push plates in the water collection tank to rotate cyclically, scraping the wall inside the water collection tank to prevent the clogging of the drain trough and prevent feces from settling and accumulating at the bottom. The first electric push rod drives the cone disk to move downward along the slide rod to compress and dehydrate the feces on the surface of the sieve plate. The sewage is sent into the anaerobic tank through the sieve plate and the filter layer, and is discharged after anaerobic aeration treatment for the next process treatment;

[0015] 2) Switching of 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, and is blown and dried by the drying fan inside the drying layer.

The feces remaining on the sieve plate are cleaned away, and then the sewage returns to the water collecting tank through the reflux pipe to continue the circulation treatment.

[0018] Furthermore, the characteristic of the cone disk in step 1 is that the bottom plane radius of the cone disk is the same as that of the sieve plate. Because the inner circle radius of the water collecting tank is larger than the radius of the filter layer, when the cone disk moves to the inner circle of the water collecting tank, it will not affect the water delivery.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention uses a drying fan inside the drying layer to blow air to dry the feces, and the original odor of the feces enters the odor treatment box for treatment. The third electric push rod drives the rotating plate of the rotating plate frame to insert into the gap of the rotating plate shaft, and then the driving motor on the back of the mounting plate controls the rotation of the rotating plate frame to drive the connecting layer and the sieve plate to flip, and the compressed and dried feces are put in. Through the connection of the connecting frame, when the mounting plate descends, the sealing plate will also synchronously open the discharge port of the water collecting box, and the push plate can push the remaining impurities in the water collecting box that cannot pass through the leakage groove out of the discharge port during the rotation process. Two collecting frames or conveying platforms are set at the bottom of the discharge port and the bottom of the delivery position to convey the feces for the preparation of organic fertilizer.

[0021] 2. The cleaning water in the cleaning frame of the present invention is the sewage after the filter layer is screened by the sieve plate, which is pumped into the cleaning frame, and then sprayed on the surface of the sieve plate through the cleaning disk and the nozzle by the delivery pump. The sieve plate at this position is the surface of the original compressed feces, and the feces remaining on the sieve plate are washed away. Then the sewage returns to the water collecting tank through the reflux pipe to continue the circulation treatment, saving water resources while keeping the cleanliness of the sieve plate.

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

[0023] 4. The present invention drives the gear to rotate through the first motor, and the gear meshes with the gear ring to drive the two push plates in the water collecting box to rotate cyclically, scraping and cleaning the inside of the water collecting box to prevent the clogging of the drain trough and prevent feces from settling and accumulating at the bottom.

[0024] 5. Compared with the prior art, the present invention uses a rotating assembly to drive two push plates in the water collecting box to rotate in a circular manner, pushing the wastewater containing feces to avoid clogging the drain tank. The sewage enters the filter layer and is compressed by the compression assembly. The sewage enters the anaerobic tank for subsequent treatment. The feces is dehydrated and rotated together with the connecting layer into the drying position for drying. The feces is then flipped over to be sent out, and the sieve plate is then cleaned, rinsed and returned for use. In this process, the sieve plate and the connecting layer are provided with four groups that can be replaced and used to avoid interrupting the time process of equipment cleaning, while preventing blockage and facilitating the delivery of feces.

9. The method for treating poultry manure wastewater according to claim 1, characterized in that: The sewage treatment method comprises the following steps: 1) Treatment of feces and sewage: After adding flocculants to poultry feces wastewater, it is passed into the water collection tank. The first motor drives the gear to rotate. The gear meshes with the gear ring to drive the two push plates in the water collection tank to rotate cyclically, scraping the wall inside the water collection tank to prevent the clogging of the drain trough and prevent feces from settling and accumulating at the bottom. The first electric push rod drives the cone disk to move downward along the slide rod to compress and dehydrate the feces on the surface of the sieve plate. The sewage is sent into the anaerobic tank through the sieve plate and the filter layer, and is discharged after anaerobic aeration treatment for the next process treatment; 2) Switching of 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, and is blown and dried by the drying fan inside the drying layer. The original odor of the feces enters the odor treatment box for treatment; 3) Delivery 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, and then the driving motor on the back of the mounting plate controls the rotation of the rotating plate frame, drives the connecting layer and the screen plate to flip, and puts the compressed and dried feces. Through the connection of the connecting frame, when the mounting plate descends, the sealing plate will also synchronously open the discharge port of the water collecting box, and the push plate can push the remaining impurities in the water collecting box that cannot pass through the leakage slot out of the discharge port during the rotation process. Two collection frames or conveying platforms are set at the bottom of the discharge port and the bottom of the delivery position to transport the feces for the preparation of organic fertilizer; 4) Cleaning of the sieve plate: The cleaning water in the cleaning frame is the sewage after the filter layer is filtered by the sieve plate. It is pumped into the cleaning frame and then sprayed on the surface of the sieve plate through the cleaning disc and nozzle by the delivery pump. The sieve plate at this position is the surface of the original compressed feces. The feces remaining on the sieve plate are cleaned away, and then the sewage returns to the water collecting tank through the reflux pipe to continue the circulation treatment.

10. A method for treating poultry manure wastewater according to claim 9, characterized in that: The characteristic of the cone disk in step 1 is that the bottom plane radius of the cone disk is the same as that of the screen plate. Because the inner circle radius of the water collecting tank is larger than the radius of the filter layer, when the cone disk moves to the inner circle of the water collecting tank, it will not affect the water delivery.
