Description

Technical Field

[0001] This utility model relates to the technical field of livestock and poultry manure treatment equipment, specifically a livestock and poultry manure fermentation device with a superimposed composting structure. Background Technology

[0002] Previously, livestock and poultry manure was considered waste, and the treatment method was often simple accumulation or direct discharge. This not only caused air and water pollution, but also wasted reusable organic matter. However, existing livestock and poultry manure fermentation devices have some significant problems in use.

[0003] In terms of mixing and cleaning functions, the stacking method of traditional devices often lacks scientificity and rationality, and the common practice is simple stacking. This leads to uneven heat distribution of the feces during fermentation, with local overheating or undercooling, which affects the activity of microorganisms and fermentation efficiency. In terms of mixing, most devices use relatively simple and inefficient mixing methods, which cannot achieve deep mixing of feces, resulting in uneven mixing of materials and over-fermentation in some areas. The problem of cleaning feces from the inner wall is often overlooked. Feces adhering to the inner wall for a long time will not only breed a large number of bacteria and pathogens, but also gradually form a thick layer of dirt. This not only hinders heat transfer and affects the fermentation process, but also increases the maintenance cost and difficulty of the device.

[0004] For example, the livestock and poultry manure tank fermentation device with announcement number CN219752195U includes a fermentation tank, a support frame fixedly installed on the outer wall of the fermentation tank, a feed inlet fixedly installed on the top of the fermentation tank, a motor fixedly installed on the top of the fermentation tank, a heat-conducting plate fixedly installed inside the fermentation tank, a discharge pipe provided at the bottom of the fermentation tank, a cover plate fixedly installed above the feed inlet, and a fermentation chamber opened inside the heat-conducting plate. In use, the aforementioned livestock and poultry manure tank fermentation device cannot achieve deep stirring and uneven mixing of manure, and cannot clean the manure from the inner wall. However, it also has other problems, such as in terms of fermentation air purification. The harmful gases and odors produced by traditional fermentation pollute the surrounding air environment. Unpurified air circulating inside the device leads to increased humidity and decreased oxygen content in the fermentation environment, thus affecting the growth and metabolism of microorganisms, reducing fermentation quality and efficiency. The lack of effective air purification measures also accelerates corrosion and aging inside the device, shortening its service life. Utility Model Content

[0005] The purpose of this invention is to provide a livestock and poultry manure fermentation device with a superimposed composting structure, in order to solve the problems mentioned in the background art, such as the inability to achieve deep mixing and uneven mixing of manure, the inability to clean the manure on the inner wall, and the inability to deal with the large amount of harmful gases and odors generated during the fermentation process, which are directly emitted into the atmosphere and seriously pollute the surrounding air environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a livestock and poultry manure fermentation device with a stacked composting structure, comprising a fermentation tank and a feed pipe installed through the upper end of the fermentation tank; a discharge pipe installed through the lower end of the fermentation tank; a layered plate is provided inside the fermentation tank, and two layered plates are provided inside the fermentation tank, with a discharge port on each layered plate; a fixing rod is fixedly installed inside the discharge port on each layered plate, and a torsion spring is provided on the outside of the fixing rod; the left front end of the torsion spring is installed on the layered plate, and a baffle is installed on the right rear end of the torsion spring, and the baffle is rotatably installed on the fixing rod; a stirring mechanism is provided inside the fermentation tank, and a stirring column is provided inside the fermentation tank; an air outlet is installed through the upper right side of the fermentation tank, and an air extractor is fixedly installed inside the air outlet; an air purification mechanism is provided at the upper end of the fermentation tank, and an exhaust pipe is fixedly installed at the upper end of the air outlet, and the exhaust pipe is C-shaped.

[0007] Furthermore, the stirring mechanism includes a motor fixedly installed at the top of the fermentation tank, with the motor output end installed in the middle of the stirring column, and tearing rods fixedly installed on the stirring column, with multiple tearing rods evenly distributed on the stirring column.

[0008] Furthermore, a tearing cone is installed on the outside of the tearing rod, and a scraper is installed on the right end of the stirring column, and the scraper cooperates with the inside of the fermentation tank.

[0009] Furthermore, the air purification mechanism includes a storage tank installed on the upper right side of the fermentation tank, and the storage tank is filled with an adsorbent liquid, which is made of potassium permanganate solution.

[0010] Furthermore, the right end of the exhaust pipe is installed through the inside of the storage tank, and the right end of the exhaust pipe is installed inside the adsorbent liquid.

[0011] Furthermore, a fixing cylinder is installed through the upper right side of the storage tank, and a first filter layer is installed on the fixing cylinder, and the first filter layer is made of activated carbon material.

[0012] Furthermore, the fixed cylinder is equipped with a second filter layer, which is installed at the right end of the first filter layer. The second filter layer is made of HEPA filter paper material.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the livestock and poultry manure fermentation device with a superimposed composting structure;

[0014] 1. Livestock and poultry manure enters the fermentation tank through the feed pipe at the top. Then, the motor is started, which drives the stirring column to rotate and stir. During the rotation, the tearing rod and tearing cone at the top of the stirring column will tear off the debris inside the livestock and poultry manure, breaking it down into smaller pieces. The rotation of the stirring column will also drive the scraper to rotate. The scraper can scrape off the livestock and poultry manure sticking to the inner wall of the fermentation tank, preventing material accumulation and ensuring the uniform distribution of heat and nutrients in the manure during fermentation. This provides a suitable growth environment for microorganisms and promotes uniform fermentation.

[0015] Furthermore, the powerful and efficient stirring, combined with the unique tearing structure, can fully break up and mix the feces, bringing the material to the optimal fermentation state and significantly shortening the fermentation time. The introduction of the wall scraping device can clean the feces on the inner wall in a timely and thorough manner, avoiding bacterial growth and dirt accumulation, maintaining the cleanliness and hygiene of the device, and reducing the risk of disease transmission. The thorough stirring and uniform stacking improve the mixing degree of the material and the oxygen supply, thereby accelerating the fermentation reaction.

[0016] Furthermore, it can remove stubborn fecal residue on the inner wall, effectively preventing the growth and reproduction of bacteria and pathogens, greatly reducing the risk of disease transmission, and maintaining the cleanliness and hygiene of the device. Because the fecal residue is cleaned in time, the heat conduction performance inside the device is maintained in a good state, avoiding local overheating or energy waste caused by dirt accumulation, and improving the efficiency and stability of fermentation.

[0017] 2. The gas produced by the fermentation of livestock and poultry manure inside the fermentation tank is extracted through the internal exhaust port and sent to the storage tank through the exhaust pipe. The storage tank contains an adsorption liquid made of potassium permanganate solution. When the gas comes into contact with it, the odor produced can be converted into a substance with a mild odor. The first filter layer inside the fixed cylinder is made of activated carbon. When odor gas molecules and some harmful gas molecules come into contact with it, they will be adsorbed by the micropores, thus purifying the gas. The second filter layer uses HEPA filter paper. When bacteria and other particulate matter collide with the filter paper fibers, they are intercepted, thus purifying the air.

[0018] Furthermore, it effectively removes harmful gases and odors produced during fermentation, which not only significantly improves the surrounding air quality and reduces environmental pollution, but also provides operators with a healthier and safer working environment, reducing the health risks caused by long-term exposure to harmful gases. The purified air circulates inside the device, maintaining suitable humidity and oxygen content, creating favorable conditions for the growth of microorganisms, and improving fermentation efficiency and quality.

[0026] 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.

[0027] Example 1: Please refer to Figures 1-6This utility model provides the following technical solution: a livestock and poultry manure fermentation device with a stacked composting structure, including a fermentation tank 1 and a feed pipe 2 installed through the upper end of the fermentation tank 1; a discharge pipe 3 installed through the lower end of the fermentation tank 1; a layered plate 4 is provided inside the fermentation tank 1, and two layered plates 4 are provided inside the fermentation tank 1, and a discharge port is opened on the layered plate 4. A fixing rod 5 is fixedly installed inside the discharge port on the layered plate 4, and a torsion spring 6 is provided on the outside of the fixing rod 5. The front left end of the torsion spring 6 is installed on the layered plate 4, and a baffle 7 is installed on the rear right end of the torsion spring 6, and the baffle 7 can rotate. A stirring mechanism is installed inside the fermentation tank 1, which is mounted on a fixed rod 5, and a stirring column 8 is also installed inside the fermentation tank 1. An air outlet 9 is installed through the upper right side of the fermentation tank 1, and an air extractor 10 is fixedly installed inside the air outlet 9. An air purification mechanism is installed at the upper end of the fermentation tank 1, and an exhaust pipe 11, which is C-shaped, is fixedly installed at the upper end of the air outlet 9. The stirring mechanism includes a motor 12 fixedly installed at the upper end of the fermentation tank 1, with the output end of the motor 12 installed in the middle of the stirring column 8. Tearing rods 13 are fixedly installed on the stirring column 8, and multiple tearing rods 13 are evenly distributed on the stirring column 8. A tearing cone 14 is installed on the outside of the tearing rod 13, and a scraper 15 is installed at the right end of the stirring column 8, and the scraper 15 cooperates with the interior of the fermentation tank 1.

[0028] Livestock and poultry manure enters the fermentation tank 1 through the feed pipe 2 at the top. Then, the motor 12 is started, which drives the stirring column 8 to rotate and stir. During the rotation, the tearing rod 13 and tearing cone 14 at the top of the stirring column 8 tear off the debris inside the livestock and poultry manure, breaking it down into smaller pieces. At the same time, the rotation of the stirring column 8 also drives the scraper 15 to rotate. The scraper 15 can scrape off the livestock and poultry manure stuck to the inner wall of the fermentation tank 1, preventing material accumulation. When the stirring is completed and it is time to discharge, the discharge port baffle 7 on the discharge pipe 3 is pressed down. During the pressing down of the baffle 7, the torsion spring 6 on the fixing rod 5 is squeezed, causing the torsion spring 6 to deform under force. At this time, the baffle 7 opens, and the material can flow out from the discharge port. Moreover, when the baffle 7 is closed, it can prevent the livestock and poultry manure below from flowing back to the top.

[0029] The air purification mechanism includes a storage tank 16 installed on the upper right side of the fermentation tank 1, and an adsorbent liquid 17 is provided inside the storage tank 16. The adsorbent liquid 17 is made of potassium permanganate solution. The right end of the exhaust pipe 11 is installed through the storage tank 16 and inside the adsorbent liquid 17. A fixing cylinder 18 is installed through the upper right side of the storage tank 16. The fixing cylinder 18 is equipped with a first filter layer 19, which is made of activated carbon. The fixing cylinder 18 is equipped with a second filter layer 20, which is installed on the right end of the first filter layer 19. The second filter layer 20 is made of HEPA filter paper.

[0030] The gas produced by the fermentation of livestock and poultry manure inside the fermentation tank 1 is extracted through the internal air extractor 10 of the air outlet 9 and sent into the storage tank 16 through the exhaust pipe 11. The storage tank 16 contains an adsorbent liquid 17 made of potassium permanganate solution. When the gas comes into contact with it, the odor produced can be converted into a substance with a mild odor, thus initially purifying the air. Then the gas enters the fixed cylinder 18 at the top of the storage tank 16. The first filter layer 19 inside the fixed cylinder 18 is made of activated carbon. When odor gas molecules and some harmful gas molecules come into contact with it, they are adsorbed by the micropores, thus purifying the gas. The second filter layer 20 uses HEPA filter paper. When bacteria and other particulate matter collide with the filter paper fibers, they are intercepted, thus purifying the air. It is particularly effective in removing suspended particulate matter.
