A new type of odorless fermentation bed for raising chickens

Abstract

This utility model relates to the technical field of poultry farming equipment and discloses a novel odorless fermentation bed for chicken farming. The bed includes a fermentation bed body, with a fan installed at the bottom of one side. A ventilation duct is fixedly connected to the fan's air inlet, and the ventilation duct is distributed in a mesh pattern at the bottom of the fermentation bed body. This novel odorless fermentation bed for chicken farming, with its bottom mesh ventilation ducts and fan forming a highly efficient ventilation system, generates negative pressure when the fan starts. Odor gases such as ammonia and hydrogen sulfide produced during fermentation are drawn to the bottom through the micropores, metal mesh, and gaps between layers of the fermentation tank. The gases first pass through a filtration unit composed of a pebble layer, an activated carbon layer, and a fine sand layer. The pebble layer initially filters dust and impurities, the activated carbon layer adsorbs odor molecules, and the fine sand layer finely filters residual impurities. The purified gas then enters the duct through ventilation holes and is discharged through a gas delivery pipe, reducing odor at its source, improving the air quality in and around the chicken house, and providing a better environment for the chickens and farmers.

Description

Technical Field

[0001] This utility model relates to the field of poultry farming equipment technology, specifically a novel odorless fermentation bed for chicken farming. Background Technology

[0002] In modern chicken farming, chicken manure produced by traditional methods not only has high treatment costs but also causes environmental pollution. Although the commonly used fermentation bed technology can degrade chicken manure to some extent, it still has many problems. The existing patent document CN220987166U discloses an ecological free-range chicken house with a fermentation bed. This utility model, through the setting of an auxiliary mechanism, when the output end of the first drive motor drives the unidirectional threaded screw to rotate forward, the drive slider drives multiple bending hooks to move laterally through bending hooks. When the output end of the first drive motor rotates in reverse, the drive roller is reset, and at the same time the second drive motor is started. The output end of the second drive motor drives the rotating roller on the rotating shaft to rotate circumferentially, thereby turning over the packing material inside the fermentation bed chamber used for fermenting chicken manure. This allows the packing material deep inside the fermentation bed chamber to fully contact the chicken manure, preventing excessive accumulation of chicken manure on top of the packing material inside the fermentation bed chamber, thus improving the fermentation effect of chicken manure.

[0003] However, existing odorless fermentation beds for chicken farming have significant shortcomings in odor control. During the fermentation process, chicken manure continuously produces gases with pungent odors, such as ammonia and hydrogen sulfide. These gases tend to diffuse randomly on the surface of the fermentation bed and in the surrounding space, making them difficult to collect and treat effectively. Due to the lack of targeted guidance and purification mechanisms, odors tend to accumulate in the chicken house, gradually increasing in concentration. This means that the odor cannot be reduced at its source, and the air quality in and around the chicken house remains poor for a long time. The pungent odor in the air not only irritates the respiratory tract of the chickens, affecting their normal growth, development, and health, and reducing farming efficiency, but also causes dizziness, nausea, and other discomfort symptoms for farmers who work in the chicken house for extended periods, affecting their work efficiency and health. As a result, both the chickens and the farmers are constantly in a less than ideal environment. Utility Model Content

[0004] Technical problems to be solved The purpose of this utility model is to provide a novel odorless fermentation bed for chicken farming, in order to solve the problem that the existing novel odorless fermentation beds for chicken farming mentioned in the background art have obvious shortcomings in odor treatment.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a novel odorless fermentation bed for chicken farming, comprising a fermentation bed body, a fan installed at the bottom of one side of the fermentation bed body, a ventilation duct fixedly connected to the air inlet end of the fan, and the ventilation duct being distributed in a mesh pattern at the bottom of the interior of the fermentation bed body; The ventilation duct is provided with ventilation holes evenly spaced. The air outlet of the fan is fixedly connected to an air supply pipe. Above the ventilation duct, from top to bottom, there are layers of pebbles, activated carbon, and fine sand. The outer sides of the three layers are separated by an isolation net to form an independent filtration unit.

[0006] As a further improvement to the above solution, a fermentation box is provided above the pebble layer. The bottom surface of the fermentation box is set at an inclined angle, and its interior is divided into multiple independent fermentation tanks by partitions with fine micropores. Fermentation agents are laid inside the fermentation tanks.

[0007] As a further improvement to the above solution, a drain pipe is provided at the lower end of the outer side of the fermentation box, and a controller is installed on one side of the fermentation bed.

[0008] As a further improvement to the above solution, each of the fermentation tanks is equipped with a temperature sensor, and a heating plate is provided at the bottom of the fermentation box, with the bottom of the heating plate adapted to the upper surface of the pebble layer.

[0009] As a further improvement to the above solution, the top of the fermentation box is covered with a metal mesh, and a bedding layer is laid on top of the metal mesh. Multiple humidity sensors are embedded in the bedding layer on the inner wall of the fermentation bed.

[0010] As a further improvement to the above scheme, a chicken coop shell is provided on the top of the fermentation bed, and a spray pump is installed in the middle of the top surface of the chicken coop shell.

[0011] As a further improvement to the above solution, the water inlet of the spray pump is connected to a water supply pipe, and the water outlet of the spray pump is fixedly connected to a spray pipe. The spray pipe is placed inside the chicken coop shell, and the nozzles are evenly distributed at the bottom of the pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This new type of odorless fermentation bed for chicken farming features a bottom mesh ventilation duct combined with a fan to form a highly efficient ventilation system. When the fan starts, it generates negative pressure, causing odorous gases such as ammonia and hydrogen sulfide produced during fermentation to gather at the bottom through the micropores, metal mesh, and gaps between layers of the fermentation tank. The gas first passes through a filter unit composed of a pebble layer, an activated carbon layer, and a fine sand layer. The pebble layer initially filters out dust and impurities, the activated carbon layer adsorbs odor molecules, and the fine sand layer finely filters out residual impurities. Afterward, the gas enters the duct through the ventilation holes, and the purified gas is discharged through the gas delivery pipe. This reduces odors at the source, improves the air quality in and around the chicken house, and provides a good environment for the chickens and farmers. 2. This new type of odorless fermentation bed for chicken farming is divided into multiple independent fermentation tanks by partitions with fine micropores inside the fermentation box. Fermentation agents can be evenly spread in each tank. After chicken manure falls through the metal mesh, it can be evenly dispersed in each fermentation tank through the micropores, ensuring full contact with the agents and avoiding local accumulation that affects decomposition efficiency. The bottom of the fermentation box is designed with an inclined angle, and with the drain pipe at the lower end of the outer side, waste liquid generated during fermentation can be quickly discharged to prevent the agents from being soaked in liquid and thus reducing their activity. At the same time, the temperature sensor built into each fermentation tank monitors the temperature inside the tank in real time. After the data is transmitted to the controller, it is linked with the heating plate at the bottom of the fermentation box. When the temperature is lower than the appropriate range, heating is automatically started, and when it is higher than the appropriate range, heating is stopped. This precise control of the fermentation environment ensures that the bacteria continuously and efficiently decompose chicken manure. 3. This new type of odorless fermentation bed for chicken farming uses multiple humidity sensors embedded in the bedding layer to monitor humidity data in different areas in real time and feed the information back to the controller. When the humidity of the bedding is lower than the standard required for fermentation, the controller automatically starts the spray pump on the top of the chicken house shell, draws water through the water supply pipe, and sprays it precisely onto the bedding layer through evenly distributed nozzles at the bottom of the spray pipe to humidify it. Once the humidity reaches the standard, the pump stops immediately, ensuring that the bedding is always within the suitable humidity range for fermentation. The metal mesh covering the top of the fermentation box allows chicken manure to fall smoothly into the fermentation tank and effectively prevents the chickens from trampling on the fermentation area, avoiding damage to the distribution of fermentation agents and temperature balance, reducing interference with the fermentation environment, and significantly improving the overall practicality of the equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a novel odorless fermentation bed for chicken farming, including a fermentation bed body 1, a fan 2 installed at the bottom of one side of the fermentation bed body 1, and a ventilation duct 3 fixedly connected to the air inlet end of the fan 2, the ventilation duct 3 being distributed in a mesh at the bottom of the interior of the fermentation bed body 1; Ventilation holes 4 are evenly distributed on the ventilation duct 3. The air outlet of the fan 2 is fixedly connected to the air supply pipe 5. Above the ventilation duct 3, from top to bottom, there are a pebble layer 6, an activated carbon layer 7, and a fine sand layer 8. The outer sides of the three layers are separated by an isolation net to form an independent filtration unit.

[0017] When the fan 2 installed at the bottom of one side of the fermentation bed 1 is started, a continuous and stable negative pressure is formed in the ventilation duct 3, which is distributed in a mesh pattern at the bottom of the fermentation bed 1. Under the action of negative pressure, the odorous gases such as ammonia and hydrogen sulfide produced during fermentation will pass through the fine micropores on the partition of the fermentation tank 10, the gaps in the metal mesh 15, and the gaps between the bedding layer 16, the pebble layer 6 (primary filtration), the activated carbon layer 7 (odor removal), and the fine sand layer 8 (fine filtration) in sequence, and gradually gather towards the ventilation duct 3 at the bottom. Finally, they enter the ventilation duct 3 through the ventilation holes 4 evenly opened on the ventilation duct 3. Under the driving force of the fan 2, these odorous gases enter the fan 2 through the air inlet end of the fan 2, and then enter the gas supply pipe 5 from the air outlet end of the fan 2.

[0018] A fermentation box 9 is installed above the pebble layer 6. The bottom of the fermentation box 9 is set at an inclined angle. Its interior is divided into multiple independent fermentation tanks 10 by partitions with thin micropores. Fermentation agents are laid inside the fermentation tanks 10. A drain pipe 11 is installed at the lower end of the outer side of the fermentation box 9. A controller 12 is installed on one side of the fermentation bed 1. Each fermentation tank 10 has a built-in temperature sensor 13. A heating plate 14 is installed at the bottom of the fermentation box 9. The bottom of the heating plate 14 is adapted to the upper surface of the pebble layer 6. The top of the fermentation box 9 is covered with a metal mesh 15, and a bedding layer 16 is laid on top of the metal mesh 15. Multiple humidity sensors 17 are embedded in the bedding layer 16 on the inner wall of the fermentation bed 1. A chicken coop shell 18 is set on the top of the fermentation bed 1. A spray pump 19 is installed in the middle of the top surface of the chicken coop shell 18. The water inlet end of the spray pump 19 is connected to a water supply pipe 20, and the water outlet end of the spray pump 19 is fixedly connected to a spray pipe 21. The spray pipe 21 is placed inside the chicken coop shell 18, and the nozzles are evenly distributed at the bottom of the pipe.

[0019] When the chickens move around on the bedding layer 16, their excreted chicken manure passes through the gaps in the metal mesh 15 and falls into the fermentation box 9 below. The fermentation box 9 is divided into multiple independent fermentation tanks 10 by partitions with fine micropores. Each fermentation tank 10 is pre-laid with a sufficient amount of fermentation inoculant. This inoculant quickly comes into contact with the falling chicken manure and begins to decompose and ferment it, converting the organic matter in the manure into harmless substances. During the fermentation process, the temperature sensor 13 built into each fermentation tank 10 continuously and in real-time monitors the temperature inside the tank and transmits the monitored temperature data as an electrical signal to the controller 12 mounted on one side of the fermentation bed 1. The controller 12 then... The received temperature data is compared with the preset suitable temperature range for the fermentation agent activity (usually 25-35℃). When the temperature is detected to be lower than this suitable range, the controller 12 will immediately issue a command to activate the heating plate 14 at the bottom of the fermentation box 9. After the heating plate 14 is powered on, it generates heat to heat the fermentation tank 10 inside the fermentation box 9. The heat is transferred through the bottom of the fermentation box 9 to each fermentation tank 10, causing the temperature inside the tank to gradually rise until it reaches the preset suitable temperature range. The controller 12 then issues a command to turn off the heating plate 14, thereby ensuring that the fermentation agent is always in a temperature environment for efficient operation. At the same time, the liquid produced during the fermentation process (such as the juice produced by the decomposition of chicken manure) is also controlled. The liquid (etc.) will flow slowly along the bottom surface of the fermentation box 9, which is set at an inclined angle, to the lower end of the outer side of the fermentation box 9, and finally be discharged in time through the drain pipe 11 to avoid the accumulation of liquid in the fermentation box 9, which would affect the activity of the fermentation agent and the fermentation efficiency. Multiple humidity sensors 17 embedded in the bedding layer 16 will monitor the humidity of different areas of the bedding layer 16 in real time and feed back the monitored humidity data to the controller 12 in real time. The controller 12 will compare the received humidity data with the preset suitable fermentation humidity range of the bedding. When the humidity of the bedding layer 16 is detected to be lower than the preset suitable value, the controller 12 will automatically issue a command to start the sprayer installed in the middle of the top surface of the chicken coop shell 18. After the spray pump 19 is started, it draws water from an external water source through the water supply pipe 20 connected to the water inlet. The drawn water enters the fixedly connected spray pipe 21 through the water outlet of the spray pump 19. The spray pipe 21 is placed inside the chicken house shell 18. The nozzles evenly distributed at the bottom of the pipe will spray water evenly onto the bedding layer 16 to humidify the bedding layer 16. When the humidity sensor 17 detects that the humidity of the bedding layer 16 has reached the preset suitable value, it will send a signal to the controller 12. The controller 12 will then issue a command to stop the operation of the spray pump 19, thereby ensuring that the bedding layer 16 is always in a humidity environment that is conducive to the function of the fermentation agent and ensuring the smooth progress of the fermentation process.

[0020] Working principle: When the chickens move around on the bedding layer 16, their excreted chicken manure passes through the gaps in the metal mesh 15 and falls into the fermentation box 9 below. The fermentation box 9 is divided into multiple independent fermentation tanks 10 by partitions with fine micropores. Each fermentation tank 10 is pre-laid with a sufficient amount of fermentation agent. This agent quickly comes into contact with the falling chicken manure and begins to decompose and ferment it, converting the organic matter in the manure into harmless substances. During the fermentation process, the temperature sensor 13 built into each fermentation tank 10 continuously and in real time monitors the temperature inside the tank and transmits the monitored temperature data in the form of an electrical signal to the controller 12 mounted on one side of the fermentation bed 1. The controller 12 will compare the received temperature data with the preset suitable temperature for the fermentation agent activity. The temperature is compared within a range (typically 25-35℃). When the temperature is detected to be below this suitable range, the controller 12 immediately issues a command to activate the heating plate 14 at the bottom of the fermentation box 9. The heating plate 14 generates heat after being powered on, heating the fermentation tanks 10 inside the fermentation box 9. The heat is transferred through the bottom of the fermentation box 9 to each fermentation tank 10, gradually increasing the temperature until the preset suitable temperature range is reached. The controller 12 then issues a command to turn off the heating plate 14, thus ensuring that the fermentation agent is always in a temperature environment conducive to efficient operation. Simultaneously, the liquid produced during fermentation (such as juice from the decomposition of chicken manure) flows slowly along the inclined bottom surface of the fermentation box 9 to the lower outer end of the fermentation box 9, and finally drains through the drain pipe 11 in a timely manner. To prevent the accumulation of liquid in the fermentation box 9, which would affect the activity of the fermentation agent and the fermentation efficiency, the fan 2 installed at the bottom of one side of the fermentation bed 1 is activated. This creates a continuous and stable negative pressure in the ventilation ducts 3, which are distributed in a mesh pattern at the bottom of the fermentation bed 1. Under this negative pressure, odorous gases such as ammonia and hydrogen sulfide produced during fermentation will pass through the fine micropores on the partition of the fermentation tank 10, the gaps in the metal mesh 15, and the gaps between the bedding layer 16, the pebble layer 6 (primary filtration), the activated carbon layer 7 (deodorization), and the fine sand layer 8 (fine filtration), gradually gathering towards the bottom ventilation duct 3. Finally, they enter the ventilation duct 3 through the evenly spaced ventilation holes 4. Driven by the fan 2, these odorous gases are then... The air enters the fan 2 through its inlet and then through the air outlet of the fan 2 into the air supply pipe 5. Multiple humidity sensors 17 embedded in the bedding layer 16 monitor the humidity of different areas of the bedding layer 16 in real time and feed the monitored humidity data back to the controller 12. The controller 12 compares the received humidity data with the preset suitable fermentation humidity range for the bedding. When the humidity of the bedding layer 16 is detected to be lower than the preset suitable value, the controller 12 automatically issues a command to start the spray pump 19 installed in the middle of the top surface of the chicken coop shell 18. After the spray pump 19 starts, it draws water from an external water source through the water supply pipe 20 connected to its inlet. The drawn water enters the fixedly connected spray pipe 21 through the outlet of the spray pump 19. The spray pipe 21 is placed inside the chicken coop shell 18.The nozzles evenly distributed at the bottom of the pipe spray water evenly onto the bedding layer 16, humidifying it. When the humidity sensor 17 detects that the humidity of the bedding layer 16 reaches a preset suitable value, it sends a signal to the controller 12. The controller 12 then issues a command to stop the spray pump 19, thus ensuring that the bedding layer 16 is always in a humidity environment conducive to the function of the fermentation agent, ensuring the smooth progress of the fermentation process.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
