Description

Technical Field

[0001] This utility model relates to the field of environmental protection and agricultural resource utilization technology, and in particular to a device for returning toilet waste to the field. Background Technology

[0002] Toilet waste, as an organic waste rich in nutrients such as nitrogen, phosphorus, and potassium, plays a vital role in sustainable agricultural development and environmental protection through resource utilization. Effective return of toilet waste to the field can not only reduce fertilizer use and lower agricultural production costs, but also improve soil structure, enhance soil fertility, and promote a virtuous cycle in the agricultural ecosystem. However, existing methods for returning toilet waste to the field present numerous problems, impacting the efficiency of resource utilization.

[0003] First, manure collection is fragmented, especially in rural areas where individual households often have scattered toilets, lacking a unified collection system. Traditional collection methods rely on manual labor, which is labor-intensive, inefficient, and prone to leakage, causing pollution to the surrounding environment. Second, the manure treatment process is inadequate. Untreated manure contains a large number of pathogens, parasite eggs, and harmful chemicals. Directly returning it to the fields may pollute the soil and crops, affecting the quality of agricultural products and human health. Although some areas use composting, parameters such as temperature and humidity are difficult to control scientifically during the composting process, resulting in incomplete decomposition and still posing environmental risks.

[0004] In addition, most existing land return equipment is rudimentary in structure and lacks specialized devices designed for the characteristics of toilet waste. As a result, uneven distribution is likely to occur during the land return process. Excessive accumulation of waste in some areas may lead to localized nutrient overload in the soil, causing seedling burn. In other areas, insufficient waste may fail to meet fertilization needs and affect crop growth and development.

[0005] Developing a device for returning toilet waste to the field, controlling temperature and humidity during composting to ensure composting effectiveness, and improving composting efficiency through centralized collection have become technical challenges that urgently need to be addressed by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a device for returning toilet waste to the field, thereby solving the problems listed in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a toilet waste returning to the field device, which includes a waste storage bin, a conveying pipeline and a distributor.

[0010] Preferably, the outer wall of the conveying pipe is wrapped with a heating layer made of thermally conductive material, and an insulation sleeve is fitted over the heating layer, with both ends of the insulation sleeve fixedly connected to the conveying pipe.

[0011] Preferably, the distributor includes a housing, a diverter plate, and multiple spray heads. The diverter plate is disposed at the center of the housing. Multiple diverter holes are opened in the middle of the diverter plate. The diameter of the diverter holes gradually decreases in three levels from the center of the housing outward. A pipe is connected below each corresponding level of hole. The pipe is fixedly connected to the inner wall of the housing.

[0017] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] like Figure 1-4 As shown, a toilet waste return-to-field device includes a waste storage bin 1, a mixing device 2, a conveying pipe 3, and a distributor 4. The waste storage bin 1 is one of the core components of the entire device. Its side wall has a feed inlet, which is sealed with a cap to prevent leakage of waste during storage. The mixing device 2 is installed inside the waste storage bin 1. The mixing device 2 consists of a drive motor 5, a transmission shaft 6, and mixing blades 7. The drive motor 5 is fixed to the top outside of the waste storage bin 1. One end of the transmission shaft 6 is connected to the output shaft of the drive motor 5 via a coupling, and the other end passes through the top of the waste storage bin 1 and extends into its interior. Multiple sets of mixing blades 7 are welded to the outer wall of the transmission shaft 6. Each set of mixing blades 7 is spirally distributed, effectively preventing waste from accumulating inside the waste storage bin 1.

[0019] The bottom of the sludge storage bin 1 is conical, with the lowest point of the conical bottom connected to the discharge port. The discharge port is connected to one end of the conveying pipe 3 via a flange. The other end of the conveying pipe 3 is connected to the distributor 4, and the connection is made through a connecting pipe 18. The connecting pipe 18 is inclined, and the purpose of the inclined setting is to allow the discharge point of the connecting pipe 18 to be directly aligned with the diversion channel 16, thereby increasing the stability of transportation. The outer wall of the conveying pipe 3 is wrapped with a heating layer 11, which is made of heat-conducting material and is used to maintain the appropriate temperature of the sludge during the transportation process. The heating layer 11 is covered with an insulation sleeve, and the two ends of the insulation sleeve are fixedly connected to the conveying pipe 3 to reduce heat loss. A booster pump can be connected to the middle of the conveying pipe 3, and the pressure change inside the conveying pipe 3 can be monitored in real time by installing a pressure gauge.

[0020] The distributor 4 includes a housing, a flow divider 9, and a spray head 10. The flow divider 9 is located at the center of the housing, and multiple flow divider holes are formed in the middle of the flow divider 9. The diameter of the flow divider holes gradually decreases in three levels from the center of the housing outward, thereby enabling uniform distribution of liquid. Each corresponding level of hole is connected to a pipe, which is fixedly connected to the inner wall of the housing. The upper surface of the flow divider 9 is provided with a flow guide groove 16, which is spirally distributed. In addition, the flow divider holes are located in the flow guide groove 16. Inside the casing, near the bottom of the inner flow divider 9, there are three drainage pipes 17, which are connected to three different levels of holes. The drainage pipes 17 are independently set and can be used with the holes to discharge liquids or materials. Multiple spray heads 10 are installed at the bottom of the casing. Each spray head 10 is connected to the casing by threads. The ends of the three drainage pipes 17 away from the holes are connected to the spray heads 10. The spray heads 10 are equipped with regulating valves, which are controlled by rotating the handle.

[0021] The inner wall of the conical bottom of the sludge storage tank 1 is coated with an anti-stick coating, which reduces the residue of feces at the bottom and facilitates thorough discharge. A level gauge 12 is installed on the outer wall of the sludge storage tank 1. The probe of the level gauge 12 penetrates the side wall of the sludge storage tank 1 and communicates with the interior of the sludge storage tank 1 to monitor the changes in the liquid level in the sludge storage tank 1 in real time. A temperature sensor 13 is also installed on the outer wall of the sludge storage tank 1. The probe of the temperature sensor 13 penetrates the side wall of the sludge storage tank 1 and communicates with the interior of the sludge storage tank 1. The signal line of the temperature sensor 13 is connected to the controller through a terminal block to monitor the temperature changes in the sludge storage tank 1. An exhaust port 14 is provided at the top of the sludge storage tank 1. An activated carbon filter 15 is installed inside the exhaust port 14. The activated carbon filter 15 is fixedly connected to the exhaust port 14 by a clamp to absorb the odor generated by the feces.

[0022] The stirring blade 7 of the stirring device 2 is provided with a scraper 8 at its edge. The scraper 8 contacts the inner wall of the sludge storage bin 1. The scraper 8 is made of flexible material and fixed to the edge of the stirring blade 7. The design of the scraper 8 can further reduce the residue of feces on the inner wall of the sludge storage bin 1.

[0023] In actual operation, the sewage enters the sewage storage 1 through the feed inlet at the top of the sludge storage 1. After the drive motor 5 starts, it drives the transmission shaft 6 and the stirring blades 7 to rotate, which fully stirs the sewage. The spiral design of the stirring blades 7 can effectively prevent the sewage from settling, while the scraper 8 scrapes off the residue on the inner wall of the sludge storage 1. The conical design at the bottom of the sludge storage tank 1 facilitates the discharge of feces from the outlet. The non-stick coating reduces the residue of feces at the bottom. The level gauge 12 and the temperature sensor 13 monitor the changes in liquid level and temperature in the sludge storage tank 1, respectively, and transmit the data to the controller to provide a reference for the operator. After the sewage enters the conveying pipe 3 from the discharge port of the sewage storage bin 1, the heating layer 11 on the outer wall of the conveying pipe 3 maintains a suitable temperature for the sewage to avoid a decrease in fluidity due to excessively low temperature. The insulation jacket further reduces heat loss. An external booster pump can be connected to improve the conveying efficiency of the sewage. A pressure gauge can be installed to monitor the pressure changes in the conveying pipe 3 in real time to ensure the stability of the conveying process. After the manure enters the housing of the distributor 4 through the conveying pipe 3, the diversion plate 9, together with the diversion channel 16, the holes and the diversion pipe 17, evenly distributes the manure to each spray head 10. The regulating valve inside the spray head 10 achieves precise flow control by rotating the handle to meet the fertilization needs of different areas.

[0024] In the above embodiments, the connection relationship between the components is clear, the structure is compact, and it is easy to manufacture and maintain. The design of the sludge storage bin 1 solves the problem of dispersed manure collection. The stirring device 2 achieves full stirring of manure. The heating layer 11 and insulation sleeve of the conveying pipe 3 ensure the temperature is suitable during the conveying process. The design of the distributor 4 solves the problem of uneven distribution of manure during the return of manure to the field. The activated carbon filter 15 in the exhaust port 14 effectively adsorbs the odor generated by manure, reducing the impact on the environment. The overall equipment structure is reasonable and can efficiently complete the collection, treatment and return of manure to the field, meeting the needs of practical applications.
