Description

Technical Field

[0001] This utility model belongs to the field of aquaculture facilities technology, specifically, it relates to a large-scale broiler farm. Background Technology

[0002] The multi-level, three-dimensional broiler farming technology, as an important technology in modern livestock and poultry farming, is gradually leading the broiler industry towards a more intensive, efficient, and intelligent direction. Traditional broiler farming methods face problems such as limited land resources, rising feed costs, and environmental pollution. The multi-level, three-dimensional broiler farming technology, using multi-layer cage systems, can fully utilize the farming space, significantly increasing the number of chickens raised per unit area. Simultaneously, this technology emphasizes the optimization and control of the farming environment, employing advanced livestock and poultry house building design and environmental control systems to precisely regulate environmental factors such as temperature, humidity, and light within the chicken house, providing a comfortable and healthy growth environment for the broilers. Furthermore, this technology integrates modern technological elements such as automation and intelligence, equipped with advanced equipment such as automated feeding systems, drinking systems, and manure removal systems, achieving automated and intelligent management of the farming process, significantly reducing labor intensity and improving farming efficiency. At the same time, the application of digital management systems makes farming data more traceable and controllable, providing a scientific basis for farming decisions.

[0003] However, large-scale broiler farming is prone to causing foul odor pollution, primarily originating from the decomposition of broiler manure. The organic matter in manure mainly includes carbohydrates and nitrogenous compounds. These organic compounds decompose under both aerobic and anaerobic conditions. When carbohydrates decompose aerobically, they release heat energy, with the main products being CO2 and water; however, under anaerobic conditions, their decomposition products are mainly methanol, organic acids, and various alcohols. These substances all have a slightly foul and sour odor, causing an unpleasant feeling. Nitrogenous compounds decompose into amino acids under the action of enzymes, which then decompose into nitrates under aerobic conditions; under anaerobic conditions, they decompose into ammonia, sulfuric acid, vinyl alcohol, dimethyl sulfide, hydrogen sulfide, methylamine, trimethylamine, and other foul-smelling gases. These gases have characteristic odors reminiscent of rotting onions, rotten eggs, or fish. Within the farm, when the manure contains excessive moisture or is compressed without fresh air, a localized anaerobic environment is created within the manure, thereby generating and releasing foul-smelling gases. In addition, there are a large number of particulate matter in the air of broiler farms. The main components of these particulate matter include feed dust, livestock and poultry excrement, mold, livestock and poultry hair and dander, and insects, which are adsorbents of many malodorous gases (such as NH3, H2S and other organic substances). Utility Model Content

[0004] Given the problem of foul odor pollution that traditional broiler farms easily cause, the purpose of this utility model is to design a farm that can handle dust and foul odor gases, so as to solve the problem of pollution of the surrounding environment caused by exhaust gases and dust from chicken farms.

[0005] To address the aforementioned technical problems, the inventors, focusing on how to remove feathers from chicken coops, reduce dust, and treat odors, designed a large-scale broiler farm, specifically providing the following technical solution:

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1: Design and Use of Large-Scale Broiler Farms

[0027] Please see Figures 1-7 As shown, a large-scale broiler farm includes a chicken house 1. A ventilation cavity 2 is provided inside the chicken house 1, and chicken cages 3 are distributed within the ventilation cavity 2. The ventilation cavity 2 is seamlessly connected to the chicken house fan vent. A feather baffle 4 is distributed on one side of the chicken cage 3, and a processing box 5 is distributed on the side of the feather baffle 4 away from the chicken cage 3. An air inlet 6 is provided on one side of the bottom of the processing box 5, and a sewage outlet 7 is provided on the bottom side of the processing box 5 away from the air inlet 6. A motor 8 is fixedly mounted on one end surface of the processing box 5, and an eccentric wheel 9 is connected to the output end of the motor 8. A guide frame 10 is fixedly mounted on the inner wall of the processing box 5, and a guide rod 11 is vertically installed on the inner side of the guide frame 10. The guide frames 10 are symmetrically distributed along the vertical center line of the processing box 5. A return spring 12 is sleeved on the outer surface of the guide rod 11, and a slider 13 is fixedly connected to the other end of the return spring 12. The return spring 12 is initially in a compressed state. When the return spring 12 is pulled, it will deform and generate a reverse force. The inner side of the slider 13 has a hole with a diameter that matches the outer diameter of the guide rod 11. The slider 13 is fixedly connected to the filter frame 14. The filter frame 14 is fixedly installed on the side of the slider 13 away from the treatment box 5. The deodorizing filter element 15 is distributed above the filter frame 14. The deodorizing filter element 15 is composed of biochar and yeast. The top of the treatment box 5 is provided with an exhaust structure.

[0028] When it is necessary to ventilate the air inside the chicken house 1, the fan 18 is turned on. The air inside the chicken house 1 will flow quickly along the ventilation cavity 2 to one side of the feather baffle 4. At this time, the feather baffle 4 blocks and separates chicken feathers and other debris in the air. The air treated by the feather baffle 4 will be drawn into the inside of the treatment box 5 through multiple air inlets 6 that are equidistantly opened on one side of the bottom. Then the motor 8 will work to make the eccentric wheel 9 connected to its output end rotate. Since the eccentric wheels 9 are distributed in the arc-shaped grooves on the front surface of the filter frame 14, when the eccentric wheels 9 rotate, the filter frame 14 will move longitudinally. At this time, the longitudinal movement of the filter frame 14 will drive the sliders 13 symmetrically arranged on both sides to slide longitudinally along the guide rods 11 vertically distributed in the inner cavity of the guide frame 10. The guide rods 11 are used to improve the stability of the filter frame 14 during longitudinal movement. While the sliders 13 are moving longitudinally, they will drive the return spring 12 to deform accordingly. Then, combined with the reverse force generated by the deformation of the return spring 12 and the rotation of the eccentric wheels 9, the longitudinal reciprocating movement of the filter frame 14 can be easily realized. At the same time, it is convenient to use the longitudinally reciprocating movement of the filter frame 14 to further filter and purify the air. The treated air is discharged through multiple filter holes 21 opened at the top of the filter frame 14. The discharged air then passes through the deodorizing filter element 15 composed of biochar and yeast for final deodorization treatment to ensure that there are no odors in the subsequently discharged air and to prevent pollution to the surrounding environment.

[0029] The exhaust structure includes a support plate 16, an exhaust pipe 17, and a fan 18. The support plate 16 is positioned directly above the deodorizing filter element 15, and the exhaust pipe 17 is fixed to the top of the support plate 16. The fan 18 is installed inside the exhaust pipe 17. When the exhaust structure is working, the fan 18 will operate periodically under the control of the controller to facilitate timed air exchange. When the fan 18 is working, it will draw the treated air into the inside of the exhaust pipe 17, and then output the air through the exhaust pipe 17. At the same time, fresh air will be introduced into the ventilation chamber 2 on the other side of the chicken house 1, achieving the purpose of ventilation.

[0030] The inner cavity of the feather baffle 4 is fixed with a filter cotton stacking plate 19, and a filter plate 20 is distributed on one side of the filter cotton stacking plate 19. Both side walls of the feather baffle 4 have slots for airflow, which facilitate subsequent filtration of chicken feathers. The upper surface of the filter frame 14 has filter holes 21, which are equidistantly distributed along the upper surface of the filter frame 14. Adsorption balls 22 are equidistantly distributed within the inner cavity of the filter frame 14. When air mixed with chicken feathers flows through the feather baffle 4, the air first passes through the slot on one side of the feather baffle 4, where the feathers are filtered out. The filtered air then enters the inner side of the feather baffle 4, where the filter cotton stacking plate 19 and filter plate 20 further filtration and purification are performed. The treated air is then output through the slot on the other side of the feather baffle 4 for further processing.

[0031] The concentration of particulate matter in the air around livestock and poultry farms is significantly higher than in other pollution-free areas, with 70%-90% of the matter being organic matter, and approximately 80%-90% of these particulate matter being PM2.5. Therefore, this invention designs components such as a circulating water tank for treating particulate matter in chicken farms. A circulating water tank 23 is located on one side of the chicken house 1, and a first water pipe 24 is connected to the bottom of the circulating water tank 23. The first water pipe 24 is controlled by a one-way valve and connects the circulating water tank 23 to the chicken house 1. A filter screen 25 is fixed inside the circulating water tank 23, and a bamboo charcoal adsorption plate 26 is distributed above the filter screen 25. When the circulating water tank 23 needs to operate, spray liquid is injected into the inside of the circulating water tank 23 in advance, so that the spray liquid can be pumped into the inside of the spray pipe by the water pump, so as to achieve subsequent spraying of air to reduce dust and particles. The sewage generated when the first spray pipe 30 sprays will accumulate in the chicken house 1. Since the circulating water tank 23 is connected to the chicken house 1 through the first water pipe 24, the spray sewage accumulated in the chicken house 1 will be pumped back into the inside of the circulating water tank 23 by the pump. With the filter screen 25 and bamboo charcoal adsorption plate 26 set in the inner cavity of the circulating water tank 23, the sewage can be filtered and purified, thereby realizing the recycling of sewage and reducing water consumption.

[0032] The inner cavity of the circulating water tank 23 is penetrated by a second water pipe 27, and one end of the second water pipe 27 is connected to a first water pump 28. The second water pipe 27 is connected to a third water pipe 29. The end of the first water pump 28 away from the second water pipe 27 is connected to the third water pipe 29, and the other end of the third water pipe 29 is connected to a first spray pipe 30. The third water pipe 29 is connected to the first spray pipe 30. A fourth water pipe 31 is distributed on one side of the second water pipe 27, and one end of the fourth water pipe 31 is connected to a second water pump 32. The output end of the second water pump 32 is connected to a fifth water pipe 33, and the other end of the fifth water pipe 33 is connected to a second spray pipe 34. The second spray pipe 34 is connected to the fifth water pipe 33. During operation, the first water pump 28 draws the filtrate composed of boric acid and dilute hydrochloric acid stored in the circulating water tank 23 into the inner side of the second water pipe 27. Then, it is introduced into the third water pipe 29 through the second water pipe 27. Since the third water pipe 29 is connected to the first spray pipe 30, the spray solution is drawn into the inner side of the first spray pipe 30 by the first water pump 28, facilitating subsequent spraying through multiple nozzles evenly distributed at the bottom of the first spray pipe 30, achieving preliminary dust suppression spraying treatment of the air. When the second water pump 32 operates, it draws the spray solution stored in the circulating water tank 23 into the inner side of the fifth water pipe 33 through the fourth water pipe 31. Then, it is introduced into the inner side of the second spray pipe 34 through the fifth water pipe 33, facilitating subsequent spraying through multiple nozzles evenly distributed at the bottom of the second spray pipe 34, further treating the air through spraying.

[0033] The air intake slots 6 are evenly distributed on the bottom of the treatment box 5 away from the drain port 7, and the air intake slots 6 and the treatment box 5 form an integrated structure. After the air has been initially treated by the feather baffle frame 4 and its internal structure, it will be drawn into the inside of the treatment box 5 through the air intake slots 6 under the action of the fan 18, so that the air can be further treated by the internal structure of the treatment box 5.

[0034] The guide frame 10 is symmetrically distributed along the vertical center line of the processing box 5, and the slider 13 is slidably connected to the guide rod 11 through the return spring 12. The guide rod 11 is vertically connected to the inner side of the guide frame 10. Under the longitudinal movement of the filter frame 14, the sliders 13 symmetrically arranged on both sides of the filter frame 14 will slide longitudinally along the guide rod 11. At this time, the longitudinally sliding slider 13 will longitudinally press the return spring 12 along the guide rod 11, realizing the deformation of the return spring 12. This facilitates the subsequent use of the reverse force generated by the deformation of the return spring 12 in conjunction with the rotation of the eccentric wheel 9 to realize the longitudinal reciprocating motion of the filter frame 14.

[0035] The exhaust pipes 17 are evenly distributed along the upper surface of the support plate 16, and the exhaust pipes 17 are hollow structures, with the bottom of the exhaust pipes 17 penetrating through the support plate 16. Since the exhaust pipes 17 are evenly distributed on the upper surface of the support plate 16, and the air inside the exhaust pipes 17 penetrates through the exhaust pipes 17 and the support plate 16, the treated air will be discharged through the exhaust pipes 17 when the fan 18 is working.

[0036] The filter holes 21 are evenly distributed along the upper surface of the filter frame 14, and the filter holes 21 and the filter frame 14 form an integrated structure. Since the filter holes 21 are evenly distributed on the upper surface of the filter frame 14, and multiple holes are also evenly opened at the bottom of the filter frame 14, the filter holes 21 can be used to effectively filter the air using the filter frame 14, and at the same time facilitate the seepage of the subsequent spray liquid.

[0037] Working process: When in use, the fan 18 generates suction, which causes the air inside the chicken house 1 to circulate along the ventilation cavity 2. At this time, under the action of the fan 18, the air inside the ventilation cavity 2 will circulate to one side of the feather baffle 4 and pass through the feather baffle 4. The multiple slots opened on one side of the feather baffle 4 can perform preliminary filtration and removal of feathers mixed in the air. Then, with the help of the filter cotton stacking plate 19 and filter plate 20 set in the inner cavity of the feather baffle 4, the purpose of filtration and dust removal is achieved. Subsequently, the air is discharged through the slot on the other side of the feather baffle 4. At this time, the first water pump 28 operates to draw the filtrate stored in the circulating water tank 23 into the inside of the second water pipe 27, and then input it into the third water pipe 29 through the second water pipe 27. Since the third water pipe 29 is connected to the first spray pipe 30, the spray liquid will eventually be input into the inside of the first spray pipe 30 under the action of the first water pump 28, so that it can be sprayed out through multiple nozzles evenly distributed at the bottom of the first spray pipe 30 to achieve the initial spray dust suppression treatment of the air. After the initial dust suppression treatment, under the action of the fan 18, air is drawn into the inside of the treatment box 5 through the air inlet slot 6 opened on one side of the bottom. At the same time, the motor 8 operates, causing the eccentric wheel 9 connected to its output end to rotate. The rotation of the eccentric wheel 9 then pushes the filter frame 14, causing the filter frame 14 to drive the sliders 13 symmetrically arranged on both sides to slide longitudinally along the guide rod 11. During the movement of the sliders 13, the return spring 12 is stretched. At this time, the return spring 12 deforms and generates a reverse force. Combined with the rotation of the eccentric wheel 9, this facilitates the subsequent longitudinal movement of the filter frame 14. The filter frame 14 reciprocates longitudinally; during this reciprocating motion, the adsorption balls 22 on its inner side further filter and adsorb the air. The treated air is then discharged through the filter holes 21. Simultaneously, when the second water pump 32 operates, it draws the spray liquid stored in the circulating water tank 23 into the inner side of the fifth water pipe 33 through the fourth water pipe 31. This liquid is then fed into the inner side of the second spray pipe 34 through the fifth water pipe 33, facilitating subsequent spraying through multiple nozzles evenly distributed at the bottom of the second spray pipe 34, thus further treating the air. Finally, the treated air is deodorized using the deodorizing filter element 15, and then discharged through the exhaust pipe 17, achieving the purpose of exhaust.
