Description

Technical Field

[0001] This invention relates to the field of harmless treatment technology for poultry and livestock manure, specifically to a microbial enzyme fermentation device for harmless treatment of poultry and livestock manure that prevents odor. Background Technology

[0002] In recent years, with the optimization and adjustment of rural and agricultural structures and the improvement of people's living standards, the livestock industry has developed rapidly, exhibiting three characteristics: First, the number of large-scale farms has increased significantly; second, farms involve large investments, high-standard equipment, and standardized management; and third, development is clearly regionalized. Currently, livestock farming areas centered on the suburbs of large and medium-sized cities have basically formed. While large and medium-sized farms have developed rapidly, the pollution and treatment of livestock manure are worrying. Some farms, due to market and recycling costs, allow manure to circulate unchecked, resulting in waste. This situation has brought serious adverse consequences: first, it causes serious resource waste; second, it pollutes the surrounding environment, affecting the health of nearby residents; and third, it exacerbates the relationship between farms and nearby villagers. Biogas projects utilize livestock manure and other raw materials to produce biogas through fermentation, achieving energy recycling. The biogas produced can be used for power generation or cooking, reducing the consumption of other energy sources; moreover, it solves the problem of manure pollution of the surrounding environment, achieving the goal of energy conservation and emission reduction. The implementation of biogas projects saves energy for the country and improves the living environment for farmers, making it a beneficial project for the country and its people.

[0003] However, existing microbial enzyme fermentation devices for poultry and livestock manure generally suffer from incomplete fermentation, which seriously affects the secondary utilization rate of poultry and livestock manure; moreover, the odorous gases produced during the fermentation process of poultry and livestock manure cause great suffering to the surrounding residents. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a microbial enzyme fermentation device for the harmless treatment of poultry and livestock manure that prevents odor.

[0005] The technical solution of the present invention is as follows: a microbial enzyme fermentation device for harmless treatment of poultry and livestock manure with odor prevention, comprising an odor prevention shed and a mixing component and a fermentation component respectively disposed inside the odor prevention shed; wall panels are slidably connected to both sides of the odor prevention shed, a partition is provided at the upper end of the interior of the odor prevention shed, an air inlet is provided on one side of the bottom surface of the partition, an odor absorbent is filled between the partition and the top of the interior of the odor prevention shed, and an induced draft fan connected to the interior of the odor prevention shed is provided at the top of the odor prevention shed and on the other side of the partition;

[0006] The mixing assembly includes a mixing box with a feed pipe at the top that passes through a partition and an odor-proof shed, two device boxes on both sides of the mixing box, a mounting frame inside the mixing box, and cutting components inside the two device boxes that can penetrate the mixing box. The feed pipe is equipped with a sealing cover. Several fixed cutting blades are evenly distributed on the two side walls of the mounting frame opposite to the two device boxes. The cutting components include two push boxes that are slidably engaged with the two device boxes, several movable cutting strips that are equidistantly distributed on the side walls of the push boxes and can penetrate the mixing box, and two push motors that are correspondingly arranged on the outer walls of the two device boxes and have push screws threadedly connected to the push boxes on their output shafts.

[0007] The fermentation assembly includes a fermenter connected to a mixing tank via a conduit, a stirring component inside the fermenter, and a stirring motor at the top of the fermenter. A peristaltic pump is installed at the connection between the fermenter and the mixing tank. An exhaust pipe and a dosing pipe, which pass through an odor-proof shed, are installed at the top of the fermenter. A discharge plate is movably hinged to the side wall of the fermenter. The stirring component includes a lifting plate that slides and engages with the inner wall of the fermenter, and several stirring paddles that rotate and engage with the lifting plate. Several pressing plates are inclined inside the lifting plate. One end of each stirring paddle is rotated and engaged with its respective lifting plate. The other end of each stirring paddle passes through the lifting plate and is equipped with a small gear. The inner wall of the fermenter is provided with toothed grooves that mesh with each of the small gears. A lifting screw that passes through the lifting plate and is threadedly connected to the lifting plate is installed on the output shaft of the stirring motor.

[0008] Furthermore, the ends of each moving cutting strip are slidably engaged with the push box, and each moving cutting strip is fitted with a return spring that abuts against the inner wall of the push box; several shafts are horizontally rotatably engaged inside the push box, the number of shafts corresponding to the number of rows of moving cutting strips on the push box, and each shaft is fitted with a cam that abuts against each moving cutting strip; one end of each shaft passes through the push box and is equipped with a connecting gear that meshes with each other, and an intermittent motor that provides power to one of the connecting gears is provided on the side wall of the push box;

[0009] Explanation: An intermittent motor drives one of the connecting gears to rotate, which in turn drives the corresponding shafts to rotate. The cams on the shafts push the moving cutting strips at their respective positions to move back and forth along the inner wall of the mixing box. The moving cutting strips and the fixed cutting discs work together to cut and crush the poultry and livestock manure, which helps to improve the crushing effect of poultry and livestock manure.

[0010] Furthermore, a lifting plate fitted onto a mounting frame is provided at the bottom of the mixing box, and a through groove is provided on the lifting plate. A connecting frame connected to the lifting plate is slidably engaged inside the mounting frame; a lifting motor is provided at the bottom of the odor-proof shed, and a lifting screw threadedly connected to the connecting frame is provided on the output shaft of the lifting motor.

[0011] Explanation: The lifting motor drives the lifting screw to rotate, which in turn moves the lifting plate as the connecting frame moves inside the mounting frame, thereby squeezing and lifting the poultry and livestock manure and improving the uniformity of the manure's texture.

[0012] Furthermore, the height directions of two adjacent cams on the same shaft are perpendicular to each other;

[0013] Explanation: By setting cams that are perpendicular to each other in the height direction, each moving cutting strip has a certain time interval while moving, thereby improving the cutting efficiency of the moving cutting strip.

[0014] Furthermore, there are two stirring components, which are symmetrically arranged in the fermentation tank and are respectively threadedly connected to the lifting screw. The two stirring components move in opposite directions.

[0015] Explanation: By setting two stirring components moving in opposite directions, the two lifting plates squeeze the poultry and livestock manure when they move closer or further apart, so that the poultry and livestock manure is mixed a second time after passing through the gap between the two adjacent pressing plates, thereby improving the fermentation uniformity of the poultry and livestock manure.

[0016] Furthermore, a filter plate is installed at the bottom of the fermentation tank, and a drain pipe is installed on the fermentation tank, located at the lower end of the filter plate and passing through the odor-proof shed.

[0017] Note: By setting up a filter plate, it is easy to separate the solid and liquid components of the fermented poultry and livestock manure, thus facilitating the classification and use of liquid fermented fertilizer and solid fermented fertilizer as needed.

[0018] Furthermore, a rack is provided at the upper end of the side wall of the wall panel, and several opening gears that mesh with the rack are equidistantly distributed on the side wall of the odor-proof shed. An opening motor is provided on the side wall of the odor-proof shed and connected to each opening gear via a chain.

[0019] Explanation: The opening motor drives the opening gears to rotate, which causes the wall panel to slide open along the odor-proof canopy under the meshing action of the rack and pinion gears, thereby improving the portability of the odor-proof canopy when opening.

[0020] Furthermore, an aeration disc is installed at the bottom of the fermentation tank, and a hot air blower connected to the aeration disc is installed at the bottom of the odor-proof shed.

[0021] Explanation: Using a hot air blower to introduce hot air into livestock manure through aeration discs helps to promote the fermentation and decomposition rate of organic matter in livestock manure, thereby improving fermentation efficiency.

[0022] Furthermore, an ultraviolet sterilization lamp is installed on the bottom surface of the partition;

[0023] Note: By setting up ultraviolet sterilization lamps, harmful gases generated during the fermentation of poultry and livestock manure can be sterilized and disinfected, thereby improving the safety of the device.

[0024] This invention also provides a microbial enzyme fermentation method for the harmless treatment of poultry and livestock manure with odor prevention, comprising the following steps:

[0025] S1. Connect the induced draft fan, drive motor, stirring motor and peristaltic pump to the external power supply respectively;

[0026] S2. Poultry and livestock manure is fed into the mixing box through the feed pipe, and biological straw is added into the mixing box; the drive motor is turned on, and the drive screw is rotated by the drive motor, so that the drive box moves inside the device box and pushes the moving cutting bar into the mixing box. The moving cutting bar and the fixed cutting blade on the mounting frame are used together to cut and crush the poultry and livestock manure and biological straw to obtain a mixture; wherein, the mass ratio of biological straw to poultry and livestock manure is 1:15~28.

[0027] S3. Turn on the peristaltic pump and stirring motor. Use the peristaltic pump to introduce the mixture from step S1 into the fermentation tank through the conduit. Then, add agricultural enzymes into the fermentation tank through the dosing pipe. Use the stirring motor to drive the lifting screw to rotate, so that the lifting plate and stirring paddle move up and down along the inner wall of the fermentation tank under the action of the lifting screw. During the movement of the lifting plate, the mixture is mixed a second time after passing through the gap between two adjacent pressing plates. At the same time, due to the meshing of the pinion and the tooth groove, each stirring paddle rotates during the up and down movement, stirring the mixture. Biogas produced during fermentation is discharged through the exhaust pipe and collected in the odor-proof shed. After fermentation, enzyme organic fertilizer is obtained. The mass ratio of agricultural enzymes to the mixture is 1:1500~2000.

[0028] S4. During the fermentation of the mixed materials, turn on the exhaust fan so that the odorous gas inside the odor-proof shed passes through the air inlet of the partition and is absorbed and treated by the odor absorbent at the top of the partition, and is finally discharged from the odor-proof shed.

[0029] S5. Open the wall panel on the odor-proof shed, then open the unloading plate on the side wall of the fermentation tank to transfer the enzyme organic fertilizer obtained in step S3.

[0030] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0031] First, the present invention integrates the mixing component and the fermentation component into a sealed odor-proof shed, and sets an odor adsorbent inside the odor-proof shed, so that the odor gas generated during the fermentation process of poultry and livestock manure can be adsorbed and purified by the odor adsorbent, thereby avoiding the pollution of the surrounding environment caused by the odor gas generated during the fermentation process of poultry and livestock manure, and also avoiding the impact of odor gas on people's lives.

[0032] Secondly, through the synergistic effect of the moving cutting strip and the fixed cutting blade, this invention achieves thorough mixing and crushing of poultry and livestock manure and biological straw, so that the beneficial bacteria in the biological straw can be evenly dispersed in the poultry and livestock manure, promoting the decomposition and transformation of organic matter in the poultry and livestock manure, and laying the foundation for the efficient fermentation of poultry and livestock manure.

[0033] Third, this invention utilizes two stirring components moving in opposite directions to stir the mixture of poultry and livestock manure and biological straw, which improves the uniformity of material mixing, avoids material accumulation at the bottom of the fermentation tank and incomplete fermentation, thereby improving fermentation efficiency and ultimately realizing the harmless and resource-based utilization of poultry and livestock manure.
