Description

Technical Field

[0001] This invention relates to the field of shallow trough fermentation technology, specifically to a shallow trough fermentation system with intelligent turning and tossing function and its fermentation process. Background Technology

[0002] Shallow trough fermentation technology is one of the core processes for the harmless treatment and resource utilization of organic solid waste. It is widely used in the organic fertilizer preparation process of organic materials such as livestock and poultry manure, crop straw, and kitchen waste. Turning and loosening the fermentation materials is a key step in shallow trough fermentation. This not only regulates the temperature and humidity of the materials and improves aeration, but also promotes uniform microbial metabolism. It is an important operation to ensure the full decomposition of materials and shorten the fermentation cycle. Due to its advantages of simple trough construction, low equipment investment, and suitability for small and medium-sized production scenarios, shallow trough fermentation has become the mainstream choice for small and medium-sized organic fertilizer processing plants and farms, with broad market application prospects. However, in actual industrial applications, existing shallow trough fermentation systems and supporting turning and loosening processes still have many technical pain points due to limitations in equipment design, functional linkage, and the level of intelligence. These limitations seriously restrict the improvement of fermentation efficiency, the stability of finished product quality, and the large-scale development of the industry. Specific problems are as follows:

[0003] The lack of intelligent control in turning operations leads to inaccurate control of fermentation temperature field: Turning equipment mostly operates on a fixed speed and fixed path mode, without setting up a real-time material temperature detection and frequency conversion linkage mechanism. It relies solely on manual experience to adjust operating parameters. During fermentation, microbial metabolism easily causes uneven local temperature fields in the material. High temperature areas are prone to premature aging of the strain and termination of fermentation, while low temperature areas delay the start of fermentation. In addition, manual inspection has data gaps, making it impossible to control in a timely and accurate manner, resulting in large differences in the maturity of the material and poor stability of the finished product quality.

[0004] Lack of coordination between turning and aeration, resulting in insufficient oxygen supply to materials: The turning mechanism and aeration system are mostly designed separately, making it impossible to achieve synchronous and full-area aeration during turning operations. After the materials are turned, they tend to clump together quickly, significantly reducing oxygen permeability. The bottom materials are prone to anaerobic fermentation and producing odors. Some simple equipment even lacks a dedicated aeration structure, relying solely on turning to achieve natural air contact, resulting in insufficient fermentation of materials. Core indicators such as the mortality rate of roundworm eggs and the rate of organic matter decomposition are difficult to meet the standards.

[0005] The lack of an automatic cleaning structure at the bottom of the liquid guiding tank leads to poor drainage of the leaking liquid and accumulation at the bottom of the tank, which not only damages the permeability of the material but also easily breeds miscellaneous bacteria, affecting the fermentation quality.

[0006] To avoid the aforementioned problems, a shallow trough fermentation system and its fermentation process with intelligent turning function are proposed to solve the existing problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a shallow trough fermentation system and its fermentation process with intelligent turning and tossing function, which solves the problems of existing shallow trough fermentation systems having no intelligent control for turning and tossing, poor coordination between turning and tossing and aeration, and easy accumulation of seepage liquid at the bottom of the trough.

A second motor is fixedly connected to the front side of the first frame, and a reciprocating screw is fixedly connected to the output shaft of the second motor through a coupling. One end of the reciprocating screw is rotatably connected to the second frame. A threaded sleeve is slidably provided on the surface of the reciprocating screw, and the bottom of the threaded sleeve is fixedly connected to the top of the gantry frame.

[0011] Preferably, the self-cleaning mechanism includes a V-shaped base, which is installed at the bottom of the fermentation tank cavity. Liquid guide pipes are installed at the bottom of the fermentation tank cavity and on both sides of the V-shaped base. Several liquid guide holes are equidistantly opened at the top of each liquid guide pipe. An auger shaft is rotatably connected to the inner wall of each liquid guide pipe, and one end of the auger shaft extends to the outside of the liquid guide pipe. A main drive pulley is fixedly connected to the surface of the reciprocating screw. An auxiliary drive pulley is fixedly connected to the surface of the auger shaft on the left side. A third belt drives between the auxiliary drive pulley and the main drive pulley. Second pulleys are fixedly connected to the surfaces of both auger shafts, and a second belt drives between the two second pulleys.

[0012] Preferably, the convenient replacement mechanism includes a multi-faceted fitting, and several multi-faceted fittings are provided, with the several multi-faceted fittings arranged around the surface of the rotating shaft. The end of the turning blade is fixedly connected to a multi-faceted assembly end head that is adapted to the multi-faceted fitting. The surfaces of the multi-faceted fitting and the multi-faceted assembly end head are provided with several through slots, and two adjacent through slots are connected by bolts.

[0013] Preferably, a first motor is fixedly connected to one side of the inner cavity of the mounting bracket, the output shaft of the first motor is fixedly connected to a rotating shaft through a coupling, and one end of the rotating shaft extends to the outside of the mounting bracket.

Temperature sensors are installed on both sides of the bottom of the mounting bracket, and a controller assembly is installed on one side of the inner cavity of the mounting bracket and on top of the first motor.

[0014] Preferably, a first limiting groove is provided on both sides of the inner cavity of the gantry frame, and a first limiting slider is slidably connected inside the first limiting groove.

[0016] This invention also discloses a shallow trough fermentation process with intelligent turning and tossing function, specifically including the following steps:

[0017] S1. Before contacting the material, the height of the mounting frame is adjusted by extending and retracting the electric telescopic rod, so that the tumbling blades in the mounting frame are in front of the material. Then, the second motor is started, which drives the reciprocating screw to rotate. The threaded sleeve of the reciprocating screw moves back and forth on the surface of the reciprocating screw. The movement of the threaded sleeve drives the mounting frame and the tumbling blades into the material area. Before entering the material area, the first motor is started in advance, which drives the rotating shaft to rotate. The rotating shaft drives the rotating shaft and several tumbling blades to rotate synchronously through the transmission cooperation of the first pulley and the first belt. The rotating blades continuously loosen and tumble the material.

[0018] During the movement of the mounting frame, the temperature sensor is moved synchronously in different areas of the material. The temperature sensor continuously detects the fermentation temperature in different areas and sends the temperature to the controller component. The controller component controls the first motor to change the frequency in different fermentation temperature areas in real time according to the fermentation temperature. The frequency change is performed according to the higher the fermentation temperature, the faster the turning speed.

[0019] S2. During the process of the rotating turning blades of the mounting frame turning the material, the blower needs to be started simultaneously. The blower sends air into the air volume main pipe at the same time. The air volume main pipe distributes the air volume to the inside of several air volume branch pipes. Finally, the material turning is aerated through the air holes on both sides of the air volume branch pipes.

[0020] S3. During the movement of the reciprocating screw carrying the tumbling blades through the rotating drive mounting frame, the reciprocating screw will synchronously drive the left auger shaft to rotate through the transmission cooperation of the main drive pulley, the auxiliary drive pulley and the third belt. The left auger shaft will synchronously drive the right auger shaft to rotate through the transmission cooperation of the second pulley and the second belt. The rotation of the auger shaft will concentrate and remove the impurities that leak from the inside of the liquid guide hole to the outside, ensuring that the filtered liquid inside the liquid guide pipe is unobstructed.

[0024] (2) The shallow trough fermentation system with intelligent turning function and its fermentation process integrate aeration and turning by setting an aeration mechanism on the mounting frame and a self-cleaning mechanism inside the fermentation tank. The turning and turning are carried out simultaneously with full-area aeration, which improves the oxygen supply efficiency of the material and eliminates anaerobic fermentation. The turning and turning operation cleans the inside of the liquid guide pipe at the same time to prevent blockage inside the liquid guide pipe, ensure smooth discharge of leachate, avoid the growth of miscellaneous bacteria, and eliminate the need for manual shutdown for cleaning. This ensures the continuous fermentation process and achieves the effect of simultaneous turning and aeration, automated cleaning inside the pipe, and efficient fermentation.

[0042] This invention also discloses a shallow trough fermentation process with intelligent turning and tossing function, specifically including the following steps:

[0043] S1. Before contacting the material, the height of the mounting frame 5 is adjusted by extending and retracting the extension end of the electric telescopic rod 4, so that the turning blades 7 in the mounting frame 5 are in front of the material. Then, the second motor 303 is started, and the second motor 303 drives the reciprocating screw 304 to rotate.

During the movement of the reciprocating screw (304) carrying the tumbling blade (7) through the rotating drive mounting frame (5), the reciprocating screw (304) will synchronously drive the left auger shaft (904) to rotate through the transmission cooperation of the main drive pulley (905), the auxiliary drive pulley (906) and the third belt (907). The left auger shaft (904) will synchronously drive the right auger shaft (904) to rotate through the transmission cooperation of the second pulley (908) and the second belt (909). The rotation of the auger shaft (904) will concentrate and remove the impurities that have leaked inside the liquid guide hole (903) to the outside, ensuring that the liquid filtered inside the liquid guide pipe (902) is unobstructed.
