Description

Technical Field

[0001] This utility model relates to the field of manure treatment technology, and more specifically to a livestock and poultry manure treatment device. Background Technology

[0002] Livestock and poultry manure mainly refers to a type of rural solid waste generated in the livestock and poultry farming industry, including pig manure, cow manure, sheep manure, chicken manure, duck manure, etc. Livestock and poultry manure has long been regarded as an important source of soil fertilizer.

[0003] Aerobic fermentation of livestock and poultry manure is a type of biological fermentation, a technology strongly promoted by the state, and a good method for producing organic fertilizer. When processing livestock and poultry manure in a fermentation tank, fermentation bacteria are added in proportion to the fermentation equipment. Temperature is controlled to activate the bacteria and maintain their propagation rate, with the temperature maintained between 60 and 75°C. Simultaneously, the mixing equipment within the fermentation equipment stirs the manure evenly at a set frequency. The entire fermentation cycle in the tank takes approximately 5 to 7 days. Finally, through aerobic fermentation by the biological bacteria, the manure is decomposed into organic fertilizer. However, existing aerobic fermentation tanks for livestock and poultry manure still have many problems in their use.

[0004] Most existing mixing methods involve vertical contact mixing of fertilizers. While this can maintain a certain level of mixing uniformity, the fertilizers inside can only be moved laterally. This results in uneven mixing of fertilizers in the upper and lower areas, leading to problems such as localized anaerobic conditions and foul odors. Utility Model Content

[0005] The purpose of this invention is to provide a livestock and poultry manure treatment device to avoid the problem of foul odor caused by local anaerobic digestion.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A livestock and poultry manure treatment device includes a treatment box, a blower, and an exhaust fan. An electric heating plate is embedded in the side wall of the treatment box. An arc-shaped partition is installed inside the treatment box, dividing the interior into a composting chamber and an aeration chamber from top to bottom. Multiple aeration holes are provided on the arc-shaped partition. The aeration chamber is connected to the blower via an air inlet pipe. A rotating shaft is horizontally arranged inside the composting chamber, and multiple turning blades are installed on the rotating shaft. A rotary motor for driving the rotating shaft is installed on the outside of the treatment box. An exhaust pipe connected to the composting chamber is provided at the top of the treatment box, and the exhaust pipe is connected to the exhaust fan via an exhaust pipe.

[0008] Furthermore, the top of the processing box is provided with a feeding cylinder that connects to the composting chamber. A rotating shaft is vertically arranged inside the feeding cylinder, and a crushing blade is fixedly connected to the rotating shaft. A drive motor for driving the rotating shaft to rotate is installed on the top of the feeding cylinder, and a feeding pipe is connected to one side of the feeding cylinder.

[0009] Furthermore, the aeration holes are inclinedly arranged on the arc-shaped partition.

[0010] Furthermore, a liquid collection box is placed at the bottom of the aeration chamber.

[0011] Furthermore, the tumbling blade has a hollow structure, and an electric heating wire is installed inside the tumbling blade.

[0012] Furthermore, a temperature sensor is installed on the side wall of the composting chamber.

[0013] Furthermore, an activated carbon deodorizing layer is provided inside the exhaust pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this application, the arc-shaped partition divides the treatment box into a composting chamber and an aeration chamber. Aeration holes are evenly distributed on the arc-shaped partition, allowing air from the aeration chamber to be evenly injected upwards into the composting chamber through the aeration holes, providing sufficient oxygen for aerobic fermentation and avoiding the odor problem caused by local anaerobic conditions. Combined with the stirring of the horizontal rotating shaft and the turning blades, the upper and lower layers of compost materials are mixed, solving the problem of "uneven mixing of fertilizer in the upper and lower areas" caused by traditional longitudinal stirring.

[0018] like Figure 1As shown, a livestock and poultry manure treatment device includes a treatment box 1, a blower 2, and an exhaust fan 3. An electric heating plate 4 is embedded in the side wall of the treatment box 1. An arc-shaped partition 5 is provided inside the treatment box 1, which divides the interior of the treatment box 1 from top to bottom into a composting chamber 101 and an aeration chamber 102. Multiple aeration holes 501 are opened on the arc-shaped partition 5. The aeration chamber 102 is connected to the blower 2 through an air inlet pipe 6. A rotating shaft 7 is horizontally arranged inside the composting chamber 101. Multiple turning blades 8 are provided on the rotating shaft 7. A rotary motor for driving the rotating shaft 7 is installed on the outside of the treatment box 1. An exhaust pipe 10 connected to the composting chamber 101 is provided on the top of the treatment box 1. The exhaust pipe 10 is connected to the exhaust fan 3 through an exhaust pipe 11.

[0019] The top of the processing box 1 is provided with a feeding cylinder 12 that connects to the composting chamber 101. A rotating shaft 13 is vertically arranged inside the feeding cylinder 12. A crushing blade 14 is fixedly connected to the rotating shaft 13. A drive motor 15 that drives the rotating shaft 13 to rotate is installed on the top of the feeding cylinder 12. A feeding pipe 16 is connected to one side of the feeding cylinder 12. The crushing blade 14 inside the feeding cylinder 12 can crush large impurities in livestock and poultry manure during feeding, reduce the particle size of the material, and increase the contact area between the fermentation material and the inoculum.

[0020] The aeration holes 501 are inclinedly arranged on the arc-shaped baffle 5; the inclined arrangement of the aeration holes 501 causes air to be sprayed obliquely upward, forming a turbulent airflow and reducing the accumulation of fecal particles at the opening of the aeration holes 501.

[0021] A liquid collection box 17 is placed at the bottom of the aeration chamber 102; the liquid collection box 17 is set up to collect the liquid that seeps out during the composting process.

[0022] The tumbling blade 8 has a hollow structure, and an electric heating wire is installed inside the tumbling blade 8.

[0023] A temperature sensor 18 is installed on the side wall of the composting chamber 101.

[0024] An activated carbon deodorizing layer 9 is provided inside the exhaust pipe 10. The activated carbon deodorizing layer 9 inside the exhaust pipe 10 can adsorb a small amount of malodorous gases such as ammonia and hydrogen sulfide generated during the composting process. Combined with the negative pressure air extraction formed by the exhaust fan, the exhaust gas is purified and the impact on the surrounding environment is reduced.

[0025] Working principle:

[0026] Livestock and poultry manure enters the feeding cylinder 12 through the feeding pipe 16. The drive motor 15 drives the rotating shaft 13 and the crushing blades 14 to crush the manure into uniform particle size. The manure falls into the composting chamber 101 through the bottom of the feeding cylinder, completing the pretreatment. The electric heating plate 4 is activated to raise the temperature of the composting chamber to 60-75°C. At the same time, the blower 2 delivers air to the aeration chamber 102 through the air inlet pipe 6. The air is evenly injected into the compost material through the aeration holes 501 of the arc-shaped partition to create an aerobic environment. The rotating motor drives the rotating shaft 7 and the turning blades 8 to rotate horizontally at a set frequency. The blades turn the upper layer of material to the lower layer and the lower layer of material to the upper layer, while pushing it to both sides to achieve three-dimensional mixing of the materials in the entire chamber and ensure uniform distribution of oxygen, temperature and bacteria. The water vapor and a small amount of waste gas generated during composting enter the exhaust pipe 11 through the exhaust pipe 10 and are transported to the activated carbon deodorization layer 19 by the exhaust fan 3. After adsorption and purification, the waste gas is discharged. At the same time, a slight negative pressure is formed in the composting chamber to prevent odor leakage.

[0027] In this invention, the horizontal turning blades 8, together with the arc-shaped partitions 5, enable the turning and mixing of the compost materials between the upper and lower layers. Combined with the blower and aeration holes, this provides sufficient oxygen for aerobic fermentation and avoids the problem of foul odor caused by local anaerobic conditions.
