Abstract
Description
Technical Field
[0001] This invention relates to the field of sheepfold deodorization technology, specifically to a time-segmented deodorization device for sheepfolds adapted to fermentation beds. Background Technology
[0002] Fermented bed sheep farming is widely used in large-scale sheep farming due to its advantages such as environmental protection and water conservation. However, sheep sheds produce malodorous substances such as ammonia and hydrogen sulfide during the farming process, and the concentration of these substances varies significantly over time, surging during peak sheep activity in the morning and evening. This not only affects the growth and health of the sheep but also pollutes the surrounding environment, making deodorization a critical requirement for fermented bed sheep farming. While current mainstream biological deodorization technologies offer the advantage of being environmentally friendly and producing no secondary pollution, existing equipment often uses a single microbial agent and a fixed spraying schedule, making it difficult to adapt to the temporal changes in malodor concentration.
[0003] Existing biological deodorization equipment has significant drawbacks: during peak hours, the deodorization efficiency of a single microbial agent is insufficient, failing to quickly reduce odor concentration; continuous spraying during off-peak hours leads to a waste of microbial agent resources. Furthermore, some equipment uses improper spraying methods, easily resulting in chemical residues (or microbial agent imbalance) that inhibit the activity of beneficial bacteria in the fermentation bed bedding, causing bedding compaction and disrupting the fermentation bed ecosystem. In addition, most equipment lacks flexible control capabilities and convenient operation and maintenance design, exhibiting poor adaptability and practicality, making it difficult to meet the dual needs of precise deodorization and ecological maintenance in fermentation bed sheep pens. Summary of the Invention
[0004] The purpose of this invention is to provide a sheepfold deodorization device that achieves rapid and efficient deodorization during peak hours and resource conservation during off-peak hours, while avoiding the inhibition of microbial communities in the fermentation bed by chemical residues. This fundamentally solves the problems of unstable deodorization effect, resource waste, and damage to the fermentation bed ecosystem caused by traditional deodorization equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The first timer is connected to the first low-pressure diaphragm pump via a line. The input end of the first low-pressure diaphragm pump is connected to the discharge port at the bottom of the left cavity via a pipeline. The output end of the first low-pressure diaphragm pump is connected to the main hose. Branch interfaces are evenly provided along the length of the main hose. Each branch interface is connected to the first nozzle. A first nozzle is also provided at the end of the main hose.
[0009] The second timer is connected to the second low-pressure diaphragm pump via a line. The input end of the second low-pressure diaphragm pump is connected to the discharge port at the bottom of the right chamber via a pipeline. The output end of the second low-pressure diaphragm pump is connected to the auxiliary hose, and the end of the auxiliary hose is provided with a second nozzle.
[0010] Preferably, the main hose is cut off at the position corresponding to the branch interface. The branch interface is T-shaped. The T-shaped interface includes a first connection port and a second connection port for connecting the two ends of the cut main hose, and a third connection port disposed between the first connection port and the second connection port and perpendicular to the line between them. The first connection port, the second connection port and the third connection port are connected, and the outer wall of the third connection port is provided with threads.
[0011] Preferably, the outer walls of the first and second connection ports are provided with threads, the first and second connection ports are inserted into the main hose, and hose clamps are provided at the connection points of the first and second connection ports and the main hose. By tightening the hose clamps, the first and second ports are pressed and fixed to the main hose to form a sealed connection structure; the third connection port is screwed to the first nozzle.
[0012] Preferably, the main hose is 10-20m long and has 6-8 branch interfaces.
[0013] Preferably, it also includes a switch and an emergency stop button. The switch and the emergency stop button are both located on the top of the main frame. The switch is connected to the emergency stop button via a circuit, and the emergency stop button is connected to the first timer and the second timer via a circuit to form a complete control loop for starting, stopping and power-off control of the equipment in an emergency.
[0014] Preferably, the discharge ports at the bottom of the left and right chambers of the dual-chamber sealed barrel are each equipped with independent valves.
[0015] Preferably, the left cavity is used to store peak-type microbial agents, and the right cavity is used to store low-peak maintenance-type microbial agents; the first timer is preset to have peak deodorization periods of 6:00-8:00 AM and 6:00-8:00 PM, and the second timer is preset to have low-peak maintenance periods of 12:00-1:00 PM.
[0016] Preferably, the peak-type microbial agent is a compound of lactic acid bacteria, yeast, and Bacillus; the low-peak maintenance-type microbial agent is a compound of Bacillus subtilis, Bacillus licheniformis, yeast, and Enterococcus faecalis.
[0017] Preferably, the main frame is provided with a transparent observation window, the double-cavity sealing cylinders are all made of transparent material and the minimum and maximum scale lines are marked on the side walls of the left and right cavities, the observation window is used to observe the remaining amount of bacterial agent in the cavity; the top of the left and right cavities are screwed with dustproof sealing caps.

[0019] In the above technical solution, a first timer, a second timer, and a dual-chamber sealed container are used. The dual-chamber sealed container independently stores peak-season compound microbial agents and low-season maintenance single microbial agents. The first and second timers control the opening and closing of corresponding low-pressure diaphragm pumps, and the peak deodorization period and low-season maintenance period are preset, with the periods being flexibly adjustable. During peak periods, a compound microbial agent containing beneficial bacteria such as lactic acid bacteria, yeast, and Bacillus is sprayed extensively into the sheepfold space through the first nozzle, rapidly degrading malodorous substances such as ammonia and hydrogen sulfide. During low-season periods, a compound microbial agent containing Bacillus subtilis, Bacillus licheniformis, yeast, and Enterococcus faecalis is sprayed directionally onto the fermentation bed through the second nozzle, replenishing beneficial bacteria and maintaining the balance of the bed's microbial community. This solution not only solves the problems of incomplete peak-season deodorization and resource waste during low-season periods in traditional equipment, but also avoids the inhibition of the fermentation bed's microbial community by chemical residues through biodegradable microbial agents and directional spraying, preventing bedding material compaction at its source.

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] like Figures 1 to 7 As shown, a time-segmented deodorization device for sheep pens adapted to fermentation beds includes a main frame 1, which is made entirely of 304 stainless steel and has dimensions of 80cm × 60cm × 120cm, suitable for passage in sheep pens. The bottom of the main frame 1 is equipped with casters 11 with brakes, allowing for flexible movement and fixed parking of the equipment, preventing displacement during operation. A storage section 12 is located on the upper side wall of the main frame 1, featuring hooks for neatly storing the main hose 8 and auxiliary hose 9, preventing them from falling to the ground and being trampled or contaminated by sheep. A raised support 13 is located at the bottom of the main frame 1, elevating the device to a certain distance, keeping the low-pressure diaphragm pump and pipelines away from manure and water on the sheep pens floor, preventing moisture-induced short circuits and corrosion of components by ammonia or hydrogen sulfide.
[0030] The main frame 1 includes an outer cover 14 and a mounting plate 15 fixedly connected inside the outer cover 14. A first timer 2 and a second timer 3 are provided at the top inside the outer cover 14. The first timer 2 and the second timer 3 are fixed on the mounting plate 15 and are installed side by side to control the deodorization operation at different times. A double-chamber sealed tank is provided in the middle of the outer cover 14. The double-chamber sealed tank is also connected to the mounting plate 15. The double-chamber sealed tank includes a left chamber 41 and a right chamber 42 that are independent of each other. The bottom of the left chamber 41 and the right chamber 42 are provided with a discharge port 43. Each discharge port 43 is equipped with an independent valve 44. The valve 44 is connected to the bacterial agent storage space inside the chamber and to the suction pipe of the corresponding low-pressure diaphragm pump. When closed, it can isolate the bacterial agent in the tank from the external pipeline to prevent the bacterial agent from flowing back, leaking or being contaminated when the equipment is idle. When opened, it provides a unique passage for the bacterial agent to enter the diaphragm pump. Before starting the equipment, the pipeline can be checked for leaks by opening the valve 44.
[0031] A transparent observation window 45 is provided on the outer cover 14. The double-chamber sealed cylinder is made of transparent material, and the minimum and maximum scale lines are clearly marked on the side wall of the double-chamber sealed cylinder. The breeder can directly observe the remaining amount of bacterial agent in the chamber through the transparent observation window 45 and replenish the bacterial agent in time. In addition, the transparent observation window 45 can be opened or closed to facilitate the replenishment of bacterial agent in the double-chamber sealed cylinder. The top of the left chamber 41 and the right chamber 42 are both equipped with dustproof sealing covers 46. The dustproof sealing covers 46 are screwed to the top of the left chamber 41 and the right chamber 42, which facilitates feeding and prevents external impurities from mixing into the bacterial agent, ensuring the purity of the bacterial agent.
[0032] The bottom of the main frame 1 is equipped with a first low-pressure diaphragm pump 5 and a second low-pressure diaphragm pump 6, both of which are fixed to the mounting plate 15. The input end of the first low-pressure diaphragm pump 5 is connected to the discharge port 43 at the bottom of the left cavity 41 via a pipeline. A first timer 2 is connected to the first low-pressure diaphragm pump 5 via a circuit for timing control of its opening and closing. The input end of the second low-pressure diaphragm pump 6 is connected to the discharge port 43 at the bottom of the right cavity 42 via a pipeline. A second timer 3 is connected to the second low-pressure diaphragm pump 6 via a circuit for timing control of its opening and closing.
[0033] The output end of the first low-pressure diaphragm pump 5 is connected to a main hose 8, which is 10-20m long. The main hose 8 has 6-8 branch interfaces 7 evenly distributed along its length. Each branch interface 7 cuts off the main hose 8 at a corresponding position, and the pipeline is connected to the first nozzle 10 via a T-shaped branch interface 7. Additionally, the first nozzle 10 is also inserted into the end of the main hose 8 furthest from the main frame 1. The T-shaped branch interface 7 includes a first connection port 71 and a second connection port 72 for connecting the two ends of the cut main hose 8, and a third connection port 73 located between the first and second connection ports 71 and perpendicular to their respective lines. The first, second, and third connection ports 71, 72, and 73 are internally interconnected, forming a complete liquid flow channel.
[0034] Both the first connection port 71 and the second connection port 72 have threads on their outer walls. They are respectively inserted into the two ends of the cut main hose 8. The threaded structure increases the friction between the interface and the inner wall of the main hose 8, improving sealing stability. Furthermore, hose clamps 74 are provided at the connection points of the first connection port 71, the second connection port 72, and the main hose 8. Tightening the hose clamps 74 compresses and fixes the T-shaped branch interface 7 to the main hose 8, forming a reliable sealed connection structure to prevent leakage of the disinfectant. The outer wall of the third connection port 73 is threaded and screwed to the first nozzle 10 for easy assembly and good sealing effect.
[0035] The output end of the second low-pressure diaphragm pump 6 is connected to a secondary hose 9, and the end of the secondary hose 9 is equipped with a second nozzle 91, which is used to spray low-peak maintenance microbial agent onto the surface of the fermentation bed in a directional manner to supplement the beneficial microbial community of the fermentation bed and maintain the balance of the microbial community.
[0036] In this embodiment, a through hole is provided on the side wall of the outer casing 14, through which both the main hose 8 and the auxiliary hose 9 extend to the outside of the outer casing 14. A switch 16 and an emergency stop button 17 are also provided on the top of the outer casing 14. The switch 16 is connected to the emergency stop button 17 via a wiring connection, and the emergency stop button 17 is connected to the first timer 2 and the second timer 3 via wiring connections, forming a complete control loop for starting, stopping, and power-off control in emergency situations. When the equipment needs to be started, pressing the switch 16 activates the control loop, and the equipment operates according to a preset time period. If an emergency occurs requiring the equipment to be stopped, pressing the emergency stop button 17 instantly cuts off the power to the entire control loop, forcing the first low-pressure diaphragm pump 5 and the second low-pressure diaphragm pump 6 to stop working, ensuring safe operation.
[0037] Left chamber 41 stores peak-period microbial agents, which are mainly composed of beneficial bacteria such as lactic acid bacteria, yeast, and Bacillus, and have a highly effective removal effect on malodorous substances such as ammonia and hydrogen sulfide in sheep pens. Right chamber 42 stores low-period maintenance microbial agents, which are composed of Bacillus subtilis, Bacillus licheniformis, yeast, and Enterococcus faecalis, and can reduce ammonia nitrogen emissions from farms and maintain the stability of the fermentation bed microbial community. The first timer 2 presets the peak deodorization period to 6:00-8:00 am and 6:00-8:00 pm, and the second timer 3 presets the low-period maintenance period to 12:00-13:00 pm, adapting to the sheep pen manure excretion pattern and achieving precise time-segmented deodorization.
[0038] The operating procedure for the sheepfold deodorization device adapted to the fermentation bed in this embodiment is as follows: First, push the deodorization device to a suitable position in the sheepfold passage and fix the device using the braking structure of the caster 11 to prevent displacement during operation. Then, unfold the main hose 8 and the auxiliary hose 9. Arrange the main hose 8 along the sheepfold passage. The first nozzle 10 is a micro-mist nozzle, which should be fixed above the sheepfold railing or the partition post (higher than the sheep's shoulders), or suspended from a simple hanging ring on the roof. It should cover the sheep's activity area horizontally and maintain a horizontal distance of not less than 50cm from the feed trough and waterer to prevent the agent from mixing into the feed or water. When fixing, it can be directly clamped to the metal railing using the matching fixing clip. If the sheepfold has no railing, plastic hanging rings can be installed on the roof in advance, and the nozzle can be fixed with a built-in telescopic hanging rope. The height and coverage area can be freely adjusted. At the same time, use small straps to fix the main hose 8 to prevent the nozzle from shifting due to sheep collisions. The second nozzle 91 is directly aimed at the surface of the fermentation bed and suspended at an appropriate height above the bed, allowing the microbial community to evenly cover the substrate. The fixing method is the same as the first nozzle 10. Then, open the dustproof sealing cap 46 of the dual-chamber sealed container, add peak-type microbial agent to the left chamber 41, and low-peak maintenance-type microbial agent to the right chamber 42. Observe the agent level through the transparent observation window 45, ensuring it is between the minimum and maximum scale lines. After adding the agent, close the dustproof sealing cap 46. Next, open the independent valves 44 at the bottom of the left chamber 41 and right chamber 42, and check for leaks at each pipe joint, T-type branch interface 7, and the connection between the main hose 8. After confirming no leaks, verify and confirm the preset time period using the first timer 2 and the second timer 3. Finally, press the switch 16 to start the equipment, activate the control circuit, and the equipment enters automatic operation mode, requiring no manual intervention.
[0039] When the equipment is running, during the peak deodorization period preset by the first timer 2 (6:00-8:00 AM and 6:00-8:00 PM), the first timer 2 triggers the first low-pressure diaphragm pump 5 to start. The peak-period microbial agent in the left chamber 41 enters the main hose 8 through the pipeline and is distributed to each first nozzle 10 through the T-shaped branch interface 77, spraying evenly into the sheepfold space to quickly degrade malodorous substances. During the low-period maintenance period preset by the second timer 3 (12:00-1:00 PM), the second timer 3 triggers the second low-pressure diaphragm pump 6 to start. The low-period maintenance microbial agent in the right chamber 42 is sprayed from the second nozzle 91 through the auxiliary hose 9 to the surface of the fermentation bed, replenishing beneficial bacteria, enhancing the degradation capacity of the bedding, and inhibiting odor rebound. If it is necessary to temporarily stop the equipment during operation, the switch 16 can be pressed again. In case of emergency, the emergency stop button 17 can be pressed directly to force power off and stop the machine. During routine maintenance, regularly check the remaining amount of bacterial agent through the transparent observation window 45, and replenish it promptly when it falls below the minimum mark. When the device is not in use, close the independent valve 44 to prevent the bacterial agent from prolonged contact with the pipeline, which could cause contamination or leakage.
[0040] This embodiment is merely an illustration of the concept and implementation of the present invention and is not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
