Description

Technical Field

[0001] This utility model relates to the field of organic waste treatment technology, and in particular to an integrated equipment for the harmless treatment of livestock farm manure. Background Technology

[0002] With the rapid development of large-scale and intensive livestock and poultry farming, the environmental treatment and resource utilization of livestock waste has become a focus of industry attention. However, for farms with small stock or rural households, limited by construction costs and farming scale, they usually do not configure large or complex professional processing lines. Instead, they generally use batch-by-batch natural composting or traditional sedimentation tank fermentation methods to treat manure. Although this traditional method has a low operating threshold, it has obvious drawbacks. Due to the large area required and the fact that it is mostly an open operation, odor is difficult to collect and control, which easily breeds mosquitoes and flies and pollutes the surrounding air and groundwater environment. At the same time, due to the lack of effective turning and turning methods, the internal temperature of the pile rises slowly, which often fails to completely kill pathogenic microorganisms and parasite eggs in the manure, making it difficult to meet the standards for harmless return to the field.

[0003] To address the aforementioned environmental pollution issues and improve treatment efficiency, integrated harmless treatment equipment has been gradually promoted and applied. Compared to traditional methods, this integrated equipment has significant advantages such as small footprint, high degree of automation, short fermentation cycle, and no secondary pollution, making it very suitable for modern environmental protection requirements. However, existing horizontal integrated fermentation equipment still has problems in actual use. To avoid mechanical wear, the internal stirring device usually leaves a safety gap between itself and the inner wall of the tank. Therefore, when treating high-viscosity, easily clumping manure, this gap and the bottom area of ​​the tank are prone to material adhesion and accumulation, becoming dead corners that mechanical stirring cannot reach. Due to the lack of agitation and oxygenation, the material in these dead corners undergoes uneven fermentation or even anaerobic putrefaction, which not only reduces the quality of a single batch but also easily causes raw materials to be mixed in with the output, affecting the final quality of the organic fertilizer. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art mentioned above, and to propose an integrated equipment for the harmless treatment of livestock farm manure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated equipment for the harmless treatment of livestock manure includes a separation chamber and a fermentation tank. A stirring rod is rotatably connected inside the separation chamber, and a rotating rod is coaxially arranged inside the fermentation tank. Blades are fixedly installed on the surface of the rotating rod, and a rotating sleeve is fixedly installed on the surface of the rotating rod. A connecting ring is rotatably connected to the surface of the rotating sleeve, and a scraper is fixedly connected to the surface of the connecting ring. A gas ejection component is installed inside the scraper.

[0006] Preferably, a stirring rod is rotatably connected inside the separation chamber, and a motor is fixedly installed outside the separation chamber, with the drive end of the motor fixedly connected to the stirring rod.

[0007] Preferably, a separation plate is fixedly installed inside the separation chamber. The separation plate is located below the stirring rod and has a horizontal groove on its surface. A liquid discharge chamber is fixedly connected to the bottom end of the separation chamber, and the liquid discharge chamber communicates with the interior of the separation chamber. A solid guide pipe is fixedly installed on the right side of the separation chamber. An auger is installed inside the solid guide pipe. The end of the solid guide pipe away from the separation chamber communicates with the interior of the fermenter. A discharge chute is opened at the bottom of the solid guide pipe on one side inside the fermenter.

[0008] Preferably, a connecting pipe is provided on the left side of the top of the fermentation tank, and a connecting pipe is provided on the right side of the top of the fermentation tank, and the blades are evenly distributed on the surface of the rotating rod.

[0009] Preferably, the gas ejection assembly includes an exhaust groove formed inside the scraper, the exhaust groove being composed of a combination of vertical and horizontal connecting grooves, the horizontal connecting groove extending to the outside of the scraper, and a one-way valve being fixedly installed inside the exhaust groove.

[0010] Preferably, a rotating ring is rotatably connected to the left side of the rotating rod, a connecting pipe is fixedly connected to the side of the rotating ring away from the rotating rod, a hollow tube is fixedly installed inside the rotating rod, a through hole one is opened on the surface of the hollow tube, and a through hole two is opened on the surface of the rotating rod.

[0011] Preferably, arc-shaped grooves are formed at equal intervals on the circumference of the rotating sleeve, and the through holes one and two are internally connected through the arc-shaped grooves and the exhaust groove.

[0012] Preferably, a waste gas discharge pipe is fixedly connected to the top of the second connecting pipe, and a feed pipe is fixedly connected to the bottom of the fermentation tank.

[0013] Compared with the prior art, this utility model provides an integrated equipment for the harmless treatment of livestock farm manure, which has the following beneficial effects: 1. This integrated equipment for the harmless treatment of manure and sewage in livestock farms uses a connecting ring and scraper inside the fermentation tank. The scraper is close to the bottom of the tank for physical scraping, and the high-pressure airflow generated by the gas ejection component inside the scraper can effectively turn over and aerate the sediment at the bottom of the tank. This not only solves the problems of easy caking at the bottom of the fermentation tank and the existence of dead corners for stirring, but also increases the contact area between the material and oxygen, ensuring the uniformity and thoroughness of fermentation.

[0014] 2. This integrated equipment for the harmless treatment of manure in livestock farms uses a one-way valve and a special intermittent ventilation structure to spray gas in a pulse form. This utilizes the explosive force of the airflow to prevent the exhaust port from being blocked by manure, thus achieving self-cleaning. On the other hand, the one-way valve effectively prevents external manure from flowing back into the air circuit when the ventilation is not in operation, ensuring the long-term stable operation of the equipment.

[0015] 3. This integrated equipment for the harmless treatment of manure and sewage in livestock farms integrates a separation chamber and a separation plate at the front end of the equipment. Before entering the fermentation stage, the manure and sewage undergo solid-liquid separation pretreatment, and excess liquid is discharged through the liquid discharge chamber. This significantly reduces the moisture content of the material entering the fermentation tank, alleviates the dehumidification and heating pressure during the fermentation process, and thus improves the overall treatment efficiency and energy saving effect.

[0020] Reference Figures 1-6 An integrated equipment for the harmless treatment of livestock manure includes a separation chamber 1 and a fermentation tank 2. A stirring rod 11 is rotatably connected inside the separation chamber 1. A rotating rod 23 is coaxially arranged inside the fermentation tank 2. Blades 24 are fixedly installed on the surface of the rotating rod 23. The blades 24 are arranged in a spiral array and have a certain inclination angle. While stirring the material, the blades can axially push the material from the feed end to the discharge end. A rotating sleeve 31 is fixedly installed on the surface of the rotating rod 23. A connecting ring 32 is rotatably connected to the surface of the rotating sleeve 31. A dustproof bearing is provided between the connecting ring 32 and the rotating sleeve 31, so that the connecting ring 32 can remain relatively stationary or swing independently relative to the rotating rod 23 under the action of gravity. A scraper 33 is fixedly connected to the surface of the connecting ring 32. A gas ejection component is provided inside the scraper 33. The bottom of the scraper 33 is attached to the bottom of the inner wall of the fermentation tank 2 to scrape off the deposited slab layer.

[0021] Reference Figures 1-3 A stirring rod 11 is rotatably connected inside the separation chamber 1. A motor is fixedly installed outside the separation chamber 1, and the drive end of the motor is fixedly connected to the stirring rod 11. A separation plate 12 is fixedly installed inside the separation chamber 1. The separation plate 12 is located below the stirring rod 11 and has horizontal grooves on its surface. A liquid discharge chamber 13 is fixedly connected to the bottom end of the separation chamber 1. The liquid discharge chamber 13 is funnel-shaped to facilitate liquid collection. The liquid discharge chamber 13 communicates with the interior of the separation chamber 1. The bottom end of the separation chamber 1 is fixedly connected to the liquid discharge chamber 13. The right side of the separation chamber 1... A solid guide pipe 14 is fixedly installed on the side. An auger is installed inside the solid guide pipe 14. The auger is driven by an independent motor. The edge of its blades fits precisely with the inner wall of the solid guide pipe 14 to form a sealing material plug effect, preventing the odor in the fermenter 2 from flowing back to the separation chamber 1. The end of the solid guide pipe 14 away from the separation chamber 1 is connected to the inside of the fermenter 2. A discharge chute is opened at the bottom of the solid guide pipe 14 on one side inside the fermenter 2. The outer wall of the fermenter 2 is provided with a heat insulation jacket, which is filled with polyurethane heat insulation foam to maintain the fermentation temperature in a low-temperature environment.

[0022] Reference Figure 3A connecting pipe 21 is provided on the left side of the top of the fermentation tank 2, and a connecting pipe 22 is provided on the right side of the top of the fermentation tank 2. The blades 24 are evenly distributed on the surface of the rotating rod 23.

[0023] Reference Figures 3-6 The gas ejection assembly includes an exhaust groove 46 formed inside the scraper 33. The exhaust groove 46 is composed of vertical and horizontal connecting grooves. The horizontal connecting groove extends to the outside of the scraper 33. A one-way valve 47 is fixedly installed inside the exhaust groove 46. The one-way valve 47 is preferably a duckbill valve, which automatically closes when the gas pressure disappears to prevent external sewage from backflowing and clogging the exhaust groove 46. A rotating ring 41 is rotatably connected to the left side of the rotating rod 23. The rotating ring 41 is provided with multiple rotating sealing rings to form a pneumatic rotating joint structure, ensuring that the connecting pipe 42 can continuously supply air to the rotating rod 23 without leakage when stationary. The side of the rotating ring 41 away from the rotating rod 23 is fixedly connected to... There is a connecting pipe 42, and a hollow pipe 43 is fixedly installed inside the rotating rod 23. The surface of the hollow pipe 43 has a through hole 44, and the surface of the rotating rod 23 has a through hole 45. The surface of the rotating sleeve 31 has arc-shaped grooves at equal intervals around its circumference. The through holes 44 and 45 are connected through the arc-shaped grooves and the exhaust groove 46. In actual use, the length of the arc-shaped groove determines the pulse duration of the gas injection. When the rotating rod 23 rotates with the motor, the through hole 45 periodically sweeps across the position of the arc-shaped groove on the inner wall of the rotating sleeve 31. Only when the two overlap, the compressed air passage is opened, and the gas is instantly ejected through the exhaust groove 46, thereby realizing mechanical pulse aeration and stirring without the need for an electrically controlled valve.

[0024] Reference Figure 1 and Figure 2 The top of the connecting pipe 22 is fixedly connected to the exhaust pipe 5, and the bottom of the fermentation tank 2 is fixedly connected to the discharge pipe 6. The discharge pipe 6 is equipped with a discharge valve to control the discharge of the decomposed organic fertilizer.

[0025] In this invention, the motor outside the separation chamber 1 is first started during use. The motor drives the stirring rod 11 to rotate inside the separation chamber 1, which initially crushes and stirs the livestock manure entering the separation chamber 1 to prevent the material from clumping. Under the action of gravity and stirring, the liquid part of the manure flows down through the horizontal groove on the surface of the separation plate 12 and enters the liquid discharge chamber 13 for unified collection and treatment. The solid manure trapped above the separation plate 12 moves to the right under the stirring force and enters the solid guide pipe 14. Subsequently, the auger inside the solid guide pipe 14 rotates, continuously conveying the solid manure to the right, and through the discharge chute located at the bottom of one side of the fermentation tank 2, the solid material is evenly pushed into the internal cavity of the fermentation tank 2, completing the feeding process.

[0026] After the material enters the fermentation tank 2, the drive device drives the rotating rod 23 to rotate continuously. The blades 24 fixed on the surface of the rotating rod 23 rotate accordingly, turning, crushing and mixing the solid manure in the tank in all directions, ensuring that the material is in full contact with the air, promoting the reproduction of aerobic microorganisms and fermentation temperature rise. At the same time, the external high-pressure gas source enters the rotating ring 41 through the connecting pipe 42, and then enters the hollow tube 43 fixed inside the rotating rod 23. The gas enters the inner cavity of the rotating rod 23 through the through hole 44 on the surface of the hollow tube 43, and finally reaches the through hole 45. Because the connecting ring 32 and the scraper 33 rotate... The moving sleeve 31 and the rotating rod 23 form a relative rotational connection. Under the action of gravity, the scraper 33 hangs naturally at the bottom of the tank or swings slowly with the material. When the rotating rod 23 rotates and the through hole 45 rotates to coincide with the position of the arc groove preset on the inner wall of the rotating sleeve 31, the high-pressure gas is instantly connected and blows open the one-way valve 47 through the exhaust groove 46, and violently sprays out from the scraper 33. The intermittent airflow can not only prevent the surface of the scraper 33 and the exhaust groove 46 from being blocked, but also use the impact force of the airflow to strongly stir the sediment dead corner at the bottom of the tank. Combined with the physical scraping of the scraper 33, it effectively solves the problems of material caking at the bottom and uneven fermentation.

[0027] During fermentation, waste gases such as ammonia and water vapor are generated. These gases rise naturally and are discharged through the exhaust pipe 5 at the top of the fermentation tank 2, which can be connected to subsequent deodorization equipment for purification. After being fully fermented and decomposed, the organic fertilizer material gradually moves towards the discharge port under the continuous pushing of the rotating rod 23 and the blade 24, and is finally discharged through the discharge pipe 6 at the bottom of the fermentation tank 2, completing the entire harmless treatment process. Throughout the process, the one-way valve 47 is closed when no gas is emitted, effectively preventing external feces from flowing back into the exhaust trough 46 and ensuring the long-term stability of the gas system.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
