Description

Technical Field

[0001] This utility model relates to the technical field of chicken manure processing equipment, and in particular to an integrated automatic manure cleaning and fermentation device for broiler chicken farming. Background Technology

[0002] Large-scale broiler farms generate a large amount of manure daily (2-3 tons per day per single shed). Traditional treatment methods mainly rely on manual manure removal or scraper-type mechanical cleaning. Manure is usually temporarily piled up in the open area outside the shed before being transported to the fermentation area. Manual manure removal is labor-intensive and time-consuming. Scrapers can only move manure laterally and cannot automatically connect to the fermentation system, resulting in long manure retention times and the continuous release of harmful gases such as ammonia and hydrogen sulfide, which deteriorates the farming environment and increases the risk of disease. Fermentation often uses trough turning or static composting. Manure and fermentation aids are mixed by loader or turner, resulting in blind spots in mixing. Uneven distribution of inoculants leads to insufficient fermentation in some areas. The core temperature can reach 70℃ while the periphery is only 40℃, with an overall maturity difference of >30%. The fermentation cycle is as long as 25-40 days, which is too long and results in low fermentation efficiency, which is not conducive to large-scale production. Utility Model Content

[0003] This utility model provides an integrated automatic manure cleaning and fermentation device for broiler farming, which solves the problems of traditional manual cleaning and transfer of chicken manure being time-consuming and labor-intensive, open-air manure treatment easily generating harmful gases that pollute the environment, and low mixing efficiency of fermentation equipment leading to long fermentation cycles that are not conducive to large-scale production.

[0004] This utility model provides an integrated automatic manure removal and fermentation device for broiler farming, including a steel frame, a fermentation tank mounted on the steel frame, a feed inlet at the top of the fermentation tank, a discharge outlet at the bottom of the fermentation tank connected to a discharge pipe, an inclined screw conveyor on one side of the fermentation tank, the high end of the screw conveyor connected to the feed inlet, and a feed hopper at the low end of the screw conveyor, a lifting pipe inside the fermentation tank, a rotating shaft inside the lifting pipe, helical blades on the rotating shaft, the upper end of the rotating shaft rotatably connected to a shaft seat at the top of the fermentation tank, a motor at the top of the fermentation tank for driving the rotating shaft, an annular material distribution plate at the upper end of the lifting pipe, the annular material distribution plate being fitted and fixed to the side wall of the lifting pipe, multiple guide plates arranged circumferentially on the side wall of the annular material distribution plate, each guide plate being connected to the rotating shaft via a positioning rod, a pesticide spraying pipe at the top of the fermentation tank, and multiple atomizing nozzles at the bottom of the pesticide spraying pipe.

[0005] In the above technical solution, each of the guide plates is arc-shaped and is arranged radially on the side wall of the annular material distribution disc.

[0006] In the above technical solution, a motor base is provided on the top of the fermenter, the motor is mounted on the motor base, and the output shaft of the motor is connected to the upper end of the rotating shaft through a coupling.

[0007] In the above technical solution, the riser pipe is connected and fixed to the inner wall of the fermenter by a support rod.

[0008] In the above technical solution, the agent spraying pipeline is connected to the liquid storage tank set on the top of the fermenter through a first liquid supply pipe, a second liquid supply pipe and a booster pump, and a solenoid valve is installed on the second liquid supply pipe.

[0009] In the above technical solution, a gate valve is provided at the lower end of the discharge pipe.

[0010] In the above technical solution, a temperature sensor is installed on the side wall of the fermenter.

[0011] As can be seen from the above technical solutions, this utility model provides an integrated automatic manure removal and fermentation device for broiler farming.

[0012] Compared with existing technologies, this invention uses a screw conveyor to transfer the manure collected by the belt conveyor in the broiler farming area to the inside of the fermentation tank in a closed manner. This saves on manual labor, prevents the continuous release of harmful gases such as ammonia and hydrogen sulfide from the manure, and ensures good safety. The motor drives a rotating shaft to vertically and spirally lift the chicken manure at the bottom of the fermentation tank to the top of the lifting pipe, and then disperse it onto an annular material distribution plate. The fermentation agent is evenly sprayed onto the annular material distribution plate through atomizing nozzles to fully contact the chicken manure. The guide plate pushes the chicken manure on the annular material distribution plate to spread it to the sides of the fermentation tank. This results in high mixing efficiency, good mixing uniformity, reduced fermentation time, and a short fermentation cycle, which is conducive to large-scale production. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] See Figure 1-5An integrated automatic manure removal and fermentation device for broiler farming includes a steel support 1 mounted on the ground, a fermentation tank 2 fixedly mounted on the support 1, a feed inlet at the top of the fermentation tank 2, a discharge outlet at the bottom of the fermentation tank 2 connected to a discharge pipe 20, and an inclined screw conveyor 3 mounted on one side of the fermentation tank 2 at a 30-degree angle to the ground. A welded column at the bottom of the screw conveyor 3 supports and fixes it to the ground. The screw conveyor 3 collects, cleans, and transports manure conveyed by the belt conveyor in the broiler farming area to the fermentation tank 2 for storage and fermentation. The high end of the screw conveyor 3 has a discharge pipe sealed to the feed inlet, and the low end of the screw conveyor 3 has a feed inlet connected to the bottom of a feed hopper 30. A lifting pipe 21 is coaxially arranged inside the lifting pipe 21, and a rotating shaft 22 is coaxially arranged inside the lifting pipe 21. Multiple spiral blades 23 are arranged vertically on the upper edge of the rotating shaft 22. The upper and lower ends of the rotating shaft 22 and the spiral blades 23 partially extend out of the lifting pipe 21. The upper end of the rotating shaft 22 is rotatably connected to the shaft seat 24 set on the top of the fermentation tank 2. A motor 25 is set on the top of the fermentation tank 2 to drive the rotating shaft 22 to rotate. An annular material distribution plate 26 is set on the upper end of the lifting pipe 21. The annular material distribution plate 26 is sleeved and fixed on the side wall of the lifting pipe 21. Three guide plates 28 are arranged on the side wall of the annular material distribution plate 26 along the circumferential direction. Each guide plate 28 is fixedly connected to the rotating shaft 22 through a positioning rod 27. A medicine spray pipe 4 is fixedly arranged on the top of the fermentation tank 2. Multiple atomizing nozzles 41 are arranged at the bottom of the medicine spray pipe 4.

[0024] In the above embodiment, the manure from the broiler breeding area is concentrated and sealed and transported to the fermentation tank 2 by the screw conveyor 3. The rotating shaft 22 driven by the motor 25 vertically and spirally lifts the chicken manure at the bottom of the fermentation tank 2 to the top of the lifting pipe 21, and then disperses it onto the annular material tray 26. The fermentation agent is evenly sprayed onto the annular material tray 26 by the atomizing nozzle 41 to fully contact the chicken manure. The chicken manure on the annular material tray 26 is pushed to the sides by the guide plate 28 to spread to the sides of the fermentation tank 2. The mixing efficiency is high and the fermentation time is reduced.

[0025] In the above embodiments, specifically, the fermentation tank 2 has a cylindrical structure, and the lower side wall of the fermentation tank 2 is a tapered side wall with a gradually decreasing diameter, which facilitates the collection of materials to the middle position at the bottom of the fermentation tank 2 and increases the material lifting efficiency.

[0026] Optionally, in the above embodiments, a sealing cover is provided on the top of the feed hopper 30, and the top of the feed hopper 30 is covered and sealed when not in use to prevent odor from leaking out.

[0027] In the above embodiments, specifically, please refer to Figure 2 , 5Each guide plate 28 is arc-shaped and radially distributed on the side wall of the annular material tray 26. The bottom of each guide plate 28 abuts against the side of the annular material tray 26. As the guide plate 28 rotates with the rotating shaft 22, it scrapes the material on the annular material tray 26 to prevent it from sticking to the annular material tray 26.

[0028] In the above embodiments, specifically, please refer to Figure 4 A motor base 251 is fixedly installed on the top of the fermentation tank 2, and a motor 25 is fixedly installed on the motor base 251. The upper end of the rotating shaft 22 extends through the top sealing plate of the fermentation tank 2 to the top of the fermentation tank 2. The output shaft of the motor 25 is connected to the upper end of the rotating shaft 22 through a coupling 252. The motor 25 and the coupling 252 facilitate stable driving of the rotating shaft 22 to rotate.

[0029] In the above embodiments, specifically, please refer to Figure 2 The riser pipe 21 is connected and fixed to the inner wall of the fermenter 2 by a support rod 211. The support rod 211 helps to maintain the stability of the riser pipe 21 inside the fermenter 2.

[0030] In the above embodiments, specifically, please refer to Figure 4 The agent spraying pipe 4 is connected to the storage tank 45 at the top of the fermentation tank 2 via the first liquid supply pipe 42, the second liquid supply pipe 43, and the booster pump 44. A solenoid valve 46 is installed on the second liquid supply pipe 43. The solenoid valve 46 is opened by the controller, and the booster pump 44 draws out the liquid from the storage tank 45 and delivers it to the agent spraying pipe 4 through the first liquid supply pipe 42 and the second liquid supply pipe 43. The agent spraying pipe 4 is circular, and multiple spray nozzles are evenly arranged along the circumference at the bottom of the agent spraying pipe 4. Each spray nozzle is connected to an atomizing nozzle 41. The agent supplied by the agent spraying pipe 4 is sprayed downward through the atomizing nozzle 41, so that the agent is fully and evenly contacted with the mixed chicken manure, which improves the fermentation mixing efficiency and reduces the fermentation time.

[0031] In the above embodiments, specifically, please refer to Figure 1 A gate valve 29 is installed at the lower end of the discharge pipe 20. The gate valve 29 facilitates the control of the discharge pipe 20 to discharge the fermented fertilizer from the fermentation tank 2.

[0032] In the above embodiments, specifically, please refer to Figure 1 A temperature sensor 5 (such as PT100 type) is installed on the side wall of the fermenter 2. The temperature probe of the temperature sensor 5 extends into the inside of the fermenter 2 to monitor the fermentation temperature inside the fermenter 2 in real time. The real-time temperature is displayed on the visible panel on the outer wall of the fermenter 2 and the data is transmitted to the external control system.

[0033] The working principle of this utility model is as follows:

[0034] 1. Chicken manure from the breeding area is transported by belt conveyor to the feed hopper 30 of screw conveyor 3;

[0035] 2. The chicken manure is conveyed upward at a 30° angle to the feed inlet of the fermentation tank 2 by the screw conveyor 3, and the manure falls into the fermentation tank 2 for further processing;

[0036] 3. After the manure is added to the fermentation tank 2, the controller starts the motor 25. The motor 25 drives the rotating shaft 22, which in turn drives the spiral blades 23 to rotate and lift the manure at the bottom of the fermentation tank 2 to the annular distribution plate 26. The agent supplied by the agent spray pipe 4 is sprayed downward through the atomizing nozzle 41, so that the agent is fully and evenly mixed with the chicken manure on the annular distribution plate 26. At the same time, the guide plate 28 scrapes the material on the annular distribution plate 26 away from the annular distribution plate 26 and disperses it to the inside of the fermentation tank 2 as it rotates with the rotating shaft 22.

[0037] 4. After mixing, monitor the fermentation temperature using temperature sensor 5;

[0038] 5. After fermentation, the organic fertilizer is discharged through the discharge pipe 20, and the discharge is controlled by the gate valve 29.

[0039] This invention achieves automatic manure collection via a screw conveyor, and solves the problem of material accumulation by utilizing a combination of a lifting pipe and a guide plate. The arc-shaped guide plate design significantly improves the uniformity of material dispersion (experiments show a dispersion efficiency increase of over 40%). The combination of a spray system and temperature monitoring ensures the controllability of the fermentation process, ultimately forming a highly efficient and low-energy integrated treatment solution. This invention can treat the large amounts of manure produced daily by large-scale broiler farms through fermentation. Compared to traditional treatment methods, this invention does not rely on manual manure removal or scraper-type mechanical cleaning. Manure does not need to be temporarily piled up in the open area outside the shed and then transported to the fermentation zone. Instead, the screw conveyor 3 directly and encloses the newly generated manure to the fermentation tank 2 for timely processing and fermentation. This avoids long manure retention time, the continuous release of harmful gases such as ammonia and hydrogen sulfide, and the deterioration of the farming environment and increase in disease risk. The fermentation cycle is significantly shortened, and the fermentation efficiency is high, which is beneficial for large-scale production.
