Abstract
Description
Technical Field
[0001] This utility model relates to the field of chicken manure processing, and in particular to a drying device for producing chicken manure organic fertilizer. Background Technology
[0002] The large-scale development of poultry farming generates a large amount of chicken manure, which, if not effectively treated, pollutes the environment. Converting chicken manure into organic fertilizer is an important resource utilization method, with drying being a key process. This process aims to reduce the moisture content for easier storage, transportation, and subsequent processing. Traditional chicken manure drying often uses composting, which is time-consuming, requires a large area, produces strong odors, and easily breeds flies, insects, and bacteria. While drum dryers improve efficiency, they are energy-intensive, bulky, and expensive. Furthermore, they present significant technical challenges due to the characteristics of chicken manure: fresh chicken manure is extremely sticky, especially when the moisture content is high. During dynamic drying and conveying, it easily adheres, clumps, and clogs the conveyor belt, leading to a sharp drop in heat exchange efficiency, poor conveying, and forced equipment shutdown for cleaning. Existing technologies commonly suffer from problems such as easy clogging of the filter screen and inconvenient cleaning and maintenance, which seriously restrict continuous and efficient production and the stable operation of the equipment. There is an urgent need to develop highly efficient and energy-saving chicken manure drying equipment that can effectively overcome adhesion and ensure filter screen permeability.
[0003] Therefore, in order to address the above problems, a drying device for producing chicken manure organic fertilizer is now being developed. Utility Model Content

The second mounting frame 2 is provided with an anti-sticking mechanism 10 for preliminary cleaning of the filter screen 6.
[0020] It also includes a feeding hopper 7, a feeding hopper 7 is provided on the upper left side of the second mounting frame 2, a cover is provided on the top of the feeding hopper 7, a discharging hopper 8 is provided on the lower right side of the first mounting frame 1, and a feeding assembly 9 is provided on the right side of the second mounting frame 2. The feeding assembly 9 is used to block chicken manure.
[0021] The feeding assembly 9 includes a mounting plate 91, which is located on the upper right side of the first mounting frame 1. An electric push rod 92 is mounted on the mounting plate 91. A baffle 93 is provided on the telescopic rod of the electric push rod 92. The baffle 93 is used to block the chicken manure and prevent the undried chicken manure from being discharged prematurely.
[0022] The anti-sticking mechanism 10 includes a drive assembly 101. The drive assembly 101 is located on the rear left side of the first mounting frame 1. The drive assembly 101 includes two conveying rollers. Two belts 102 are wound between the conveying rollers. A push plate 103 is located between the belts 102. A cleaning brush 104 is installed at the bottom of the push plate 103. The cleaning brush 104 can perform preliminary cleaning of the chicken manure adhering to the filter screen 6 during the movement.
[0023] It also includes a recycling mechanism 11, which includes a collection frame 111. The collection frame is slidably provided at the bottom of the first mounting frame 1. A pull rod 112 is installed on the right side of the collection frame. Two locking parts 113 are rotatably connected to the lower right side of the first mounting frame 1. The locking parts 113 are used to block the collection frame 111.
[0024] It should be noted that the working principle of this chicken manure organic fertilizer drying device is a continuous process that combines hot air drying, mechanical vibration conveying, real-time anti-sticking cleaning, and material recovery control. Production begins when the operator opens the cover on top of the feed hopper 7 and puts the wet chicken manure with a high moisture content into the feed hopper 7. The wet chicken manure falls into the second mounting frame 2 above through the feed hopper 7. At this time, the material discharge component 9 located on the right side of the second mounting frame 2 is in working condition. Specifically, the electric push rod 92 on the mounting plate 91 extends and drives the baffle 93 to a low position, blocking the chicken manure material from flowing to the right and ensuring that the chicken manure is confined within the second mounting frame 2 for initial treatment. The hot air module 3, located at the rear of the first mounting frame 1, is activated. This module generates high-temperature hot air, which is blown from back to front into the main processing chamber formed by the first mounting frame 1 and the second mounting frame 2, heating the interior of the chamber. Simultaneously, the dehumidification module 4, located at the top of the second mounting frame 2, starts working, continuously extracting the generated hot and humid air from inside and quickly expelling it from the device, effectively reducing the ambient humidity inside the chamber and creating a drying environment dominated by low humidity and high temperature, thus accelerating the dehydration of wet chicken manure. At the same time, the vibrator 5, installed at the rear of the middle of the first mounting frame 1, begins working, generating a specific frequency... The horizontal excitation force of the vibrator 5 is transmitted through the mounting frame structure to the filter screen 6 inside the first mounting frame 1, causing the entire filter screen 6 to generate high-frequency horizontal reciprocating vibration. The wet chicken manure falling on the filter screen 6 is continuously thrown, shaken, and spread out under this continuous horizontal vibration. Simultaneously, fine chicken manure fragments or dust can pass through the mesh of the filter screen 6. More importantly, the horizontal driving force generated by the vibrator 5 drives the chicken manure material on the filter screen 6 to overcome frictional resistance and continuously and gradually move horizontally to the right side of the device, forming a unique horizontal vibration conveying system. As the chicken manure vibrates... Moving horizontally to the right, the chicken manure is temporarily blocked and piled up when it approaches the baffle 93. Under the combined action of continuous hot air drying, continuous dehumidification by the dehumidification module 4, and high-frequency tumbling generated by the vibration of the filter screen 6, the piled-up chicken manure is fully heated and efficiently dried. When the batch of chicken manure has reached the preset drying requirements, the electric push rod 92 retracts, lifting and resetting the baffle 93, releasing the obstruction of the chicken manure material. The dried or nearly dried chicken manure, no longer obstructed by the baffle 93, continues to move to the right under the continuous drive of the horizontal vibration of the filter screen 6, and finally passes through the outlet located on the lower right side of the first mounting frame 1. The hopper 8 slides out of the device, completing the drying and discharge process. To prevent the wet chicken manure from sticking and clogging the surface of the filter screen 6 due to its sticky properties during the drying process, the drive assembly 101 drives two conveyor rollers to rotate synchronously. The two belts 102 wrapped around the conveyor rollers move in a circular motion. The push plate 103, which is set between the two belts 102 and fixedly connected to them, moves in a straight reciprocating motion along the top of the filter screen 6 under the drive of the belts 102, approximately in the length direction of the filter screen 6. The cleaning brush 104, which is rigidly installed at the bottom of the push plate 103, has its bristles close to or even slightly in contact with the surface of the filter screen 6.As the push plate 103 moves linearly, the cleaning brush 104 continuously sweeps back and forth across the upper surface of the filter screen 6, initially scraping, breaking up, and cleaning up the chicken manure that is not completely dried or sticky and adhering to the edges of the mesh or clogging the mesh openings. This maintains the permeability of the filter screen 6, ensuring that the drying hot air can smoothly penetrate the material layer and also ensuring the smoothness of the vibration conveying process. Below the filter screen 6, to prevent dry and wet fine dust that leaks through the mesh openings during the aforementioned process from flying around or falling to the ground, and to facilitate collection and treatment, a collection frame 111 of the recycling mechanism 11 is slidably installed at the bottom of the first mounting frame 1. Throughout the drying process, due to the vibration of the filter screen 6, fine particles separated from the wet chicken manure are collected and processed. Dry dust particles, clumps swept off by the cleaning brush 104, and any possible fragments will continue to fall naturally through the filter screen 6 into the collection frame 111 located below. At appropriate times (e.g., after the drying batch is finished), the worker can manually release the two locking pieces 113 that are rotatably connected to the lower right side of the first mounting frame 1, causing it to rotate away from the blocking position. Then, by pulling the pull rod 112 fixed to the right side of the collection frame 111, the entire collection frame 111 can be pulled out from the bottom of the device along the guide rail. The collected dry chicken manure powder can be cleaned or recycled for subsequent granulation or reused as raw material. After emptying, it is pushed back into place and re-secured with the locking pieces 113, ready for the next batch of work.
