Description

Technical Field

[0001] This invention belongs to the field of manure transportation technology, specifically a manure transportation system for healthy beef cattle farming. Background Technology

[0002] Livestock and poultry manure contains a lot of organic matter and mineral elements needed for crop growth. However, direct application of livestock and poultry manure to the field is inconvenient due to its high water content. Furthermore, livestock and poultry manure has a low carbon and nitrogen content, and the vigorous activity of microorganisms consumes oxygen in the soil, competing with crops and causing slow crop growth or even wilting. Therefore, it is necessary to collect and separate the manure in advance and then produce waste or biogas. The traditional transportation method is to use pumps for direct transportation, which is not convenient and also has the problem of untimely manure treatment.

[0003] To address the aforementioned issues, Chinese Patent CN113197107A discloses a multi-story pig manure conveying system. The two-story pig manure collection system is located below the first-story system. Both systems include manure channels, with four channels in total. A scraper is installed inside each channel, and a sedimentation transfer hopper is installed at the front end of each channel. An installation plate is positioned above the sedimentation transfer hopper, and a suction auger pump is installed at the lower end of the installation plate. A branch PVC conveying pipe is installed at one end of the suction auger pump, and a main PVC conveying pipe is installed at one end of the branch PVC conveying pipe. A main PVC conveying pipe is connected between the main PVC conveying pipe and the sedimentation tank.

[0004] The above-mentioned technical solution effectively solves the problems of inconvenient and untimely transportation of feces and sewage. However, the feces and sewage will produce a strong odor during the transportation process. If a large amount of feces and sewage accumulates for a long time, it will also produce odorous substances such as ammonia, hydrogen sulfide and skatole after fermentation and decomposition, which will cause serious pollution to the surrounding environment. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a manure transportation system for healthy beef cattle farming, which can conveniently transport and separate manure into solid and liquid components, and also treat the odor of manure during transportation to reduce environmental pollution.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A manure conveying system for healthy beef cattle farming includes a first deodorization device, a second deodorization device, and a separation device. The first deodorization device has a first pipe and a manure conveying pipe on its side. The first deodorization device is connected to the second deodorization device through the first pipe. A booster pump is installed above the second deodorization device. The separation device is located below the second deodorization device and contains a dehydration tank. A pneumatic device is installed at the lower end of the separation device. The air inlet of the pneumatic device is connected to the second deodorization device through the second pipe. The separation device has a drainage pipe connected to a biogas digester. A first valve is installed on the first pipe, and a second valve is installed on the second pipe.

[0008] The above solution achieved the following beneficial effects:

[0009] Fecal waste is transported through a waste conveying pipe to the first deodorization device. A compound microbial deodorizing agent is added to the first device, and the waste undergoes preliminary deodorization under its action. The waste is then transported through a first pipe to a second deodorization device. After transport, the valves on both pipes are closed, and a booster pump is activated to pressurize the second deodorization device. This high pressure alters the permeability of bacterial cell membranes, inhibiting bacterial enzyme activity and the replication of DNA and other genetic material, thus killing odor-causing bacteria. The second valve is then opened, and compressed air enters the pneumatic device through the second pipe. The expansion of the compressed gas converts pressure energy into mechanical energy, causing the pneumatic device's output shaft to rotate, which in turn rotates the dehydration tank, dehydrating the waste within. Due to centrifugal force, the liquid in the waste is squeezed into a separation device, which then transports the liquid through a drainage pipe to a biogas digester. The dehydrated waste can then be transported to a factory for fertilizer production. This method solves the environmental pollution problem caused by the lack of odor treatment during the waste transportation process in existing technologies.

[0010] Furthermore, the first deodorization device is provided with a first sewage inlet and a sewage outlet on its side. The first sewage inlet is fixedly connected to the sewage conveying pipe, and the sewage outlet is fixedly connected to the first pipeline. A first liquid level sensor is installed on the inner wall of the first deodorization device, and a feeding port is provided on the top of the first deodorization device. A first cover is threadedly connected to the feeding port.

[0011] Beneficial effects: Fecal waste is transported from the fecal waste conveying pipe to the first deodorization device. When the amount of fecal waste reaches the height of the first liquid level sensor, the first liquid level sensor will sound an alarm to alert the staff, making it easier to control the amount of fecal waste in the first deodorization device. After opening the cover, a compound microbial deodorizing agent is added to the first deodorization device. After a short period of fermentation, the initial deodorization is completed, reducing some of the odorous bacteria in the fecal waste gas.

[0012] Furthermore, the second deodorization device is provided with a second sewage inlet and a high-pressure air outlet on its side. The high-pressure air outlet is located above the second sewage inlet. The second sewage inlet is fixedly connected to the first pipe. A second liquid level sensor is installed on the inner wall of the second deodorization device. The lower end of the second deodorization device is conical, and a second cover is provided at the conical opening.

[0013] Beneficial effects: After initial deodorization, the fecal waste is transported from the first pipe to the second deodorization device. When the amount of fecal waste reaches the height of the second liquid level sensor, the second liquid level sensor will sound an alarm to alert the staff, making it easier to control the amount of fecal waste in the first deodorization device. After closing the first and second valves, the high-pressure pump pressurizes the second deodorization device, using high pressure to kill the odor-causing bacteria in the fecal waste. The second deodorization device further deodorizes the fecal waste, reducing the odor-causing bacteria in the fecal waste gas again.

[0014] Furthermore, the pneumatic device passes through the bottom of the separator and is fixedly connected to the dehydration barrel. Several drainage holes are provided on the side and bottom of the dehydration barrel. The bottom of the separator is conical, and several drainage outlets are provided on the bottom surface of the separator. All drainage outlets are connected and connected. One end of the drainage pipe is connected to the drainage outlet, and the other end of the drainage pipe is connected to the biogas digester.

[0015] Beneficial effects: The compressed gas in the second deodorization device enters the pneumatic device through the air inlet. The expansion of the compressed gas drives the pneumatic output shaft to rotate, which in turn drives the dehydration tank to rotate. Through centrifugal force, the liquid in the feces is discharged from the drain hole of the dehydration tank to the bottom of the separation device. The compressed gas generated when high pressure kills odor bacteria is effectively used to separate the feces into solid and liquid components.

[0016] Furthermore, the air outlet of the pneumatic device is connected to a purification mechanism via a pipe. The purification mechanism contains several activated carbon plates, and an air outlet pipe is provided on the side of the purification mechanism.

[0017] Beneficial effects: The gas discharged from the pneumatic device passes through the activated carbon plate in the purification mechanism. The residual odor bacteria in the gas will adhere to the activated carbon, which will filter the air again and make the emitted gas more environmentally friendly.

[0018] Furthermore, a septic tank pump is installed on the first pipe, and a water pump is installed on the drain pipe.

[0019] Beneficial effects: After initial deodorization, the fecal waste needs to be transported to the second deodorization device. The sewage pump can accelerate the entry of the fecal waste into the second odor treatment device, and the water pump can effectively discharge the liquid in the separation device, avoiding the liquid from remaining in the separation device for a long time and causing pollution.

[0020] Furthermore, the inner wall of the second deodorization device is provided with an isolation plate, which has several air holes. The isolation plate is located between the high-pressure exhaust port and the second sewage inlet.

[0021] Beneficial effects: The partition plate separates the feces and sewage into two parts. When compressed gas is discharged, impurities in the feces and sewage will not be discharged into the pneumatic device along with the compressed gas, reducing the chance of internal damage to the pneumatic device caused by impurities.

[0022] Furthermore, a drive motor is installed at the lower end of the first deodorization device, and a stirring shaft is coaxially and fixedly connected to the drive motor.

[0023] Beneficial effects: After adding the compound microbial deodorizer into the first deodorization device, the fecal waste will ferment and deodorize. Stirring the fecal waste inside can fully integrate the fecal waste with the compound microbial deodorizer, enhancing the initial deodorization effect of the first deodorization device.

[0024] Furthermore, a nylon mesh filter bag is detachably connected inside the dehydration tank.

[0025] Beneficial effects: After the manure in the dehydration bucket is dehydrated, the dried manure needs to be transported to the fertilizer plant to be made into fertilizer. The nylon mesh filter bag can be removed directly to pack the dried manure, making the transportation of dried manure more convenient. Attached Figure Description

A first cover 101 is threadedly connected to the feeding port.

[0034] The second deodorizing device 2 has a second sewage inlet and a high-pressure air outlet on its side. The second sewage inlet is fixedly connected to and communicates with the first pipe 5. The high-pressure air outlet is located above the second sewage inlet. The inner wall of the second deodorizing device 2 is provided with an isolation plate 202. The isolation plate 202 is provided with several air holes. The isolation plate 202 is located between the high-pressure exhaust outlet and the second sewage inlet. The second sewage inlet is fixedly connected to the first pipe 5. A second liquid level sensor 203 is installed below the isolation plate 202 on the inner wall of the second deodorizing device 2. The second liquid level sensor 203 is an XT803-F multi-functional liquid level alarm and control instrument. The lower end of the second deodorizing device 2 is conical, and a second cover 204 is provided at the conical opening.

[0035] Three support legs are fixedly connected to the lower surface of the separation device 3. The pneumatic device 13 passes through the bottom of the separation device 3 and is fixedly connected to the dehydration tank 4. Several drainage holes 302 are provided on the side and bottom of the dehydration tank 4. A nylon mesh filter bag 301 is detachably connected inside the dehydration tank 4. The bottom of the separation device 3 is conical, and several drainage outlets 303 are provided on the bottom surface of the separation device 3. All drainage outlets 303 are connected and connected. One end of the drainage pipe is connected to the drainage outlet 303, and the other end of the drainage pipe is connected to the biogas digester. The air outlet of the pneumatic device 13 is connected to the purification mechanism 10 through a pipe. Several activated carbon plates 304 are provided inside the purification mechanism 10, and an air outlet pipe is fixedly connected to the side of the purification mechanism 10.

[0036] The specific implementation process is as follows:

[0037] The collected fecal waste is transported to the first deodorizing device 1 through the fecal waste conveying pipe 14. When the amount of fecal waste reaches the limit set by the first liquid level sensor 102, the first liquid level sensor 102 will alarm, prompting the staff to stop transporting fecal waste into the first deodorizing device 1. The first cover 101 is opened, and an appropriate amount of compound microbial deodorizing agent is added into the first deodorizing device 1. After closing the first cover 101, the pneumatic drive motor 12 is activated. The output shaft of the drive motor 12 drives the stirring shaft 103 to rotate and stir the fecal waste and compound microbial deodorizing agent in the first deodorizing device 1. Large pieces of fecal waste are stirred into smaller pieces for easy transport, allowing the fecal waste and compound microbial deodorizing agent to fully blend. The compound microbial deodorizing agent can ferment with the fecal waste and kill some of the odor-causing bacteria in the fecal waste. Since the fermentation process between the compound microbial deodorizing agent and the fecal waste is relatively short, preliminary deodorization can be completed after a short stirring time. Then, the drive motor 12 is turned off and the sewage pump 7 and the first valve 8 are started. The sewage pump 7 transports the fecal waste in the first deodorizing device 1 to the second deodorizing device 2.

[0038] When the sewage reaches the limit set by the second liquid level sensor 203, the second liquid level sensor 203 alarms, prompting the staff to stop supplying sewage into the second deodorizing device 2, close the first valve 8 and the second valve 9, and turn on the two booster pumps 201 to pressurize the second deodorizing device 2. This high pressure alters the permeability of bacterial cell membranes, thereby inhibiting the activity of bacterial enzymes and the replication of genetic material such as DNA, thus killing remaining odor-causing bacteria. The second valve 9 is then opened to release compressed gas, which enters the pneumatic device 13 through the air inlet. The expansion effect drives the pneumatic device 13 to rotate, which in turn drives the dehydration bucket 4 to rotate. The compressed gas is discharged from the air outlet of the pneumatic device 13 and then through the four-layer activated carbon plate 304 in the purification mechanism 10 to the outside. When the first batch of fecal waste is deodorized, there is no fecal waste in the dehydration bucket 4. Clean water can be added to the dehydration bucket 4. When the dehydration bucket 4 rotates, the clean water can clean the inner wall of the dehydration bucket. The cleaned sewage is discharged to the biogas digester through the drain pipe. After the compressed gas is discharged, the second cover 204 is opened to discharge the fecal waste that has undergone secondary deodorization into the nylon mesh filter bag 301 in the dehydration bucket 4.

[0039] After the next batch of manure enters the second deodorization device 2 for high-pressure sterilization, the discharged compressed gas will drive the pneumatic device 13 to rotate, causing the dehydration tank 4 to rotate, thereby dehydrating the manure in the nylon mesh filter bag 301. The liquid squeezed out by centrifugal force will be drawn from the drain outlet 303 into the drain pipe, and then transported to the biogas digester by the water pump 11. The remaining dry manure in the nylon mesh filter bag 301 can be directly packaged and transported to the fertilizer plant to make fertilizer. The entire transportation process not only separates the manure into solid and liquid components, but also deodorizes the manure, reducing the environmental impact during transportation.
