Description

Technical Field

[0001] The present application relates to the technical field of aerobic fermentation composting, and specifically discloses a light-type solid-liquid separation device for livestock and poultry manure. Background Art

[0002] At present, many farms generally add antibiotics to feed in order to increase the growth rate of livestock and poultry, prevent diseases, and improve breeding efficiency. However, livestock and poultry can usually only absorb a small amount of antibiotics, and about 60% to 90% of antibiotics are excreted in feces. These unabsorbed antibiotics enter the soil and water bodies through wastewater and applied manure, leading to antibiotic contamination of water sources and soil. At the same time, these antibiotics may also affect the structure and activity of soil microbial communities, and even enter water sources or food chains through agricultural irrigation or fertilization. Long-term accumulation may cause microorganisms to develop resistance to antibiotics, thereby affecting the health of the ecosystem and even causing bacterial resistance problems, increasing public health risks; Composting has been proven to significantly reduce antibiotic residues in livestock and poultry manure, such as tetracycline, chloramphenicol, and gentamicin. Under suitable composting conditions, the degradation rate of antibiotics can reach 50%-90%. However, since livestock and poultry manure usually contains a large amount of water, excessive water will hinder the oxygen supply when directly composted, resulting in slower microbial activity, a slower composting process, and the production of foul odors. Therefore, first removing the liquid portion through solid-liquid separation to reduce the moisture content in the solid manure will help improve the aeration of the compost, promote the activity of aerobic microorganisms, and thus accelerate the decomposition of organic matter. Currently commonly used solid-liquid separation equipment, such as screw extruders and filter presses, separate solids from liquids by applying external force; Although composting can promote the degradation of antibiotics under high temperature and the action of microorganisms, it is usually carried out in a dark environment, and the impact of light is rarely considered. The degradation of antibiotics mainly depends on the degradation and hydrolysis of microorganisms, and the longer treatment cycle may not be suitable for the rapid treatment needs of large-scale farms and agricultural production. Studies have shown that appropriate light can significantly promote the degradation of antibiotics in livestock and poultry manure, increase the diversity of bacterial communities and the abundance of bacteria related to organic matter degradation, while not affecting the total abundance of bacteria in the manure. In view of this, the present invention provides a light-type livestock and poultry manure solid-liquid separation device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0016] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0017] The figure marks in the drawings of the specification include: feed port 1, heat exchanger 2, pressing spiral roller 3, reducer 4, motor 5, box 6, temperature sensor 7, liquid output port 8, waste liquid purification chamber 9, first infrared light LED lamp 10, solid output port 11, ultraviolet light LED lamp 12, control switch 13, humidity sensor 14, second infrared light LED lamp 15.

[0018] Implementation example Figure 1 and Figure 2 As shown: A light-type livestock and poultry manure solid-liquid separation device includes a solid-liquid separation body, the solid-liquid separation body including a box body 6, a feed port 1 provided at the top of the box body 6, a multi-stage squeezing screw system provided inside the box body 6 for achieving solid-liquid separation, a light-emitting system provided at the top of the box body 6, a solid output port 11 and a waste liquid purification chamber 9 provided on one side and at the bottom of the box body 6, respectively, and a liquid output port 8 opened at the bottom of the waste liquid purification chamber 9; It also includes an intelligent control system and a waste heat recovery system for recovering waste heat. The intelligent control system includes a sensor, a control module and a control panel. The intelligent control system controls the multi-stage pressing screw system, the lighting system and the waste heat recovery system.

[0019] About the lighting system: The lighting system is a multispectral lighting system, which includes an ultraviolet light source and an infrared light source. The ultraviolet light source and the infrared light source are both arranged in a box 6. The ultraviolet light source and the infrared light source are both provided with a control switch 13. The control switch 13 controls the intensity of the ultraviolet light source and the infrared light source. The control switch 13 is electrically connected to the sensor.

[0020] The ultraviolet light source and the infrared light source are divided into an ultraviolet LED lamp 12 and an infrared LED lamp. The sensor includes a temperature sensor 7 and a humidity sensor 14. The ultraviolet LED lamp 12 is arranged on the inner top of the box body 6. Figure 1 As shown, the infrared light LED lamp includes a first infrared light LED lamp 10 and a second infrared light LED lamp 15 . The first infrared light LED lamp 10 is arranged at the top inside the box 6 , and the second infrared light LED lamp is arranged at the bottom side of the box 6 .

[0021] Specifically: the control panel controls the sensor based on the control module, and the sensor monitors the temperature and humidity in the box 6, and adjusts the intensity of the ultraviolet LED lamp 12 and the infrared LED lamp by controlling the temperature and humidity; UV light wavelengths range from 200 nm to 280 nm, with the UVC band effectively killing bacteria and viruses and breaking down antibiotics. UV light intensity ranges from 50 to 100 μW / cm², ensuring uniform and effective illumination throughout the solid-liquid separation chamber and promoting photocatalytic reactions. Stronger UV light helps break down antibiotic residues. UV LED lamps have a power of between 10W and 20W. The infrared light has a wavelength range of 700 nm to 1500 nm, an intensity range of 500 to 1000 μW / cm², and a power range of 30 W to 50 W. It is installed on both sides of the solid-liquid separation chamber. The infrared band primarily produces thermal energy, which can accelerate water evaporation, reduce system energy consumption, and improve processing efficiency. The multispectral lighting system is equipped with an intelligent dimming module with a dimming range of 20% to 100%. Due to the presence of the temperature sensor 7 and the humidity sensor 14, under the action of the sensors, the ultraviolet LED lamp 12 and the infrared LED lamp adjust the light intensity to effectively kill bacteria and viruses and decompose antibiotics.

[0022] like Figure 1 As shown: The multi-stage squeezing screw system includes a squeezing screw roller 3, a reducer 4 provided on the outer wall of a box body 6, and a motor 5 connected to the reducer 4, wherein the motor 5 is electrically connected to the control module.

[0023] Specifically: The squeezing spiral roller 3 is tubular and consists of multiple spiral segments. There are at least four segments from front to back, each with a different pitch. The spiral speed is adjusted based on the material's properties (e.g., moisture content, particle size). The first segment has a pitch of 30 mm; the second segment has a pitch of 20 mm; the third segment has a pitch of 15 mm; and the fourth segment has a pitch of 10 mm. As the material progresses through the system, the pitch gradually decreases, thereby strengthening the squeezing effect on the material and improving the solid-liquid separation effect. The action peak of each spiral segment also varies. The pitch of each spiral segment is set accordingly. For example, the squeezing force in the first segment is 50 N; the second segment has a squeezing force of 100 N; the third segment has a squeezing force of 150 N; and the fourth segment has a squeezing force of 200 N. In the first segment, the squeezing force is relatively low, primarily providing initial squeezing of the material. In subsequent segments, the squeezing force gradually increases to squeeze out as much moisture as possible from the material. The solid content and dehydration efficiency of each stage will also affect the overall separation effect; The inner wall of the housing 6, the solids outlet 11, and the liquid outlet 8 are coated with a special antimicrobial coating. This coating is applied to the inner wall of the housing 6, the solids outlet 11, and the liquid outlet 8, and has a smooth surface, typically covering key metal surfaces. The selected antimicrobial coating material has long-lasting durability, with a coating thickness of 50 μm to ensure a long-lasting antimicrobial effect without affecting the mechanical properties and operation of the device. The coating material is a copper ion coating with strong antimicrobial properties. The waste liquid purification chamber 9 is connected to the bottom of the box body 6. The waste liquid purification chamber 9 is a funnel-shaped structure. The funnel-shaped structure of the waste liquid purification chamber 9 can accelerate the waste liquid to enter the liquid output port 8 and be discharged from the liquid output port 8; The waste heat recovery system includes a heat exchanger 2, a pump, a valve and a control system. The heat exchanger 2 is a plate heat exchanger 2. The heat input end of the heat exchanger 2 is installed in the box 6, and the heat output end of the heat exchanger 2 has a heating device outside.

[0024] Specifically: The heat generated by the lighting system is converted into usable heat energy for use in the engine power supply and other aspects of the system. This heat comes from the lamps and the multi-stage squeezing screw system. The collected waste heat is transferred to water or air through a heat exchange device and used to supply other heating equipment, reducing energy consumption. The waste heat recovery system is connected to an intelligent control system, which can dynamically adjust the heat collection and utilization efficiency according to the indoor temperature and energy consumption. It also includes an automatic spray cleaning system, which includes a water tank, water pipes, a water pump and a nozzle. The nozzle is arranged on the inner wall of the box body 6, the waste liquid purification chamber 9, the solid output port 11, the feed port 1 and the liquid output port 8. The automatic spray cleaning system is connected to the control module. The water flow rate sprayed by each nozzle is usually between 0.5-1 L / min. The spraying liquid is usually a mixture of warm water and chlorine-containing disinfectant, with a concentration of generally 1% to 3%. The water pressure used by the nozzle is usually between 2 and 5 bar to ensure that the cleaning liquid is evenly sprayed and fully covers the surface of the equipment. The time for each cleaning process is between 30 minutes and 1 hour, which is set according to the area of ​​the equipment and the degree of contamination.

[0025] Material flow: The material enters the box 6 from the feed port 1, passes through the lighting system, and then enters the high-efficiency multi-stage squeezing screw system. After multiple stages of squeezing and dehydration, the solid material is discharged through the solid output port 11 and the liquid is discharged through the liquid output port 8.

[0026] The device solves the problem that traditional composting technology has limited effect on removing antibiotics.
