The efficiency and stability of their processing have become crucial for industrial upgrading. Currently, in the field of biopesticide processing, traditional models have significant shortcomings, with core issues concentrated in the fragmented processing flow and high reliance on manual labor, severely restricting capacity expansion.

[0003] CN220643064U discloses a biological pesticide production device, including an extraction tank and a threaded top cover that rotates on the top of the extraction tank. A drive motor is mounted on the top of the threaded top cover, and the output end of the drive motor extends below the threaded top cover and is connected to a centrifuge cylinder via a connecting rod. A feed through-hole is provided on one side of the top of the centrifuge cylinder, and a feed pipe is installed through one side of the threaded top cover, with a feed hopper connected to the top of the feed pipe. A discharge pipe is connected to the bottom of the extraction tank, and a control valve is installed on the discharge pipe.

[0005] The purpose of this invention is to address the shortcomings of existing technologies in effectively freeing up manpower and reducing production costs while ensuring efficient production and reasonable processes. Therefore, this invention proposes a biological pesticide production device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A biopesticide production apparatus includes a support base and a processing assembly. A control cabinet is fixedly mounted on top of the support base. The control cabinet contains a program capable of precisely controlling the operating parameters of an activation tank, a horizontal fermenter, and a combined drying tower, ensuring automated operation of the entire process. A processing assembly is fixedly connected to the top of the support base on one side of the control cabinet. The processing assembly includes an activation tank, which is cylindrical and mounted on top of the support base. A horizontal fermenter is fixedly installed on the side of the activation tank away from the control cabinet. The horizontal fermenter has an elliptical, curved body. A combined drying tower is fixedly installed on the side of the horizontal fermenter away from the activation tank. Two sets of conveying pipes are fixedly connected to both sides of the horizontal fermenter. Each set of conveying pipes conveys the material in the activation tank to the horizontal fermenter and the material in the horizontal fermenter to the combined drying tower, respectively. A self-priming pump is connected to the middle of the conveying pipe. Two hanging brackets are fixedly connected to the inner wall of the activation tank at about one-third to two-thirds of the tank height. The hanging brackets are circular and adapted to the inner wall of the cylindrical tank. Two carrier nets are fixedly connected inside each of the two hanging brackets. The carrier nets are mesh products made of polypropylene, polyester fiber, and ceramic fiber. An enamel layer is fixedly connected to the inner wall of the activation tank at the top and bottom of the two hanging brackets. The smooth inner wall design of the enamel layer ensures that the bile liquid material adheres to the wall during feeding, avoiding oxidation reaction between the liquid material and the metal inner wall of the activation tank.

[0008] As a further embodiment of this utility model: a supporting rotating column is rotatably connected to the inner wall of the horizontal fermentation tank, and multiple sets of inclined blade stirring paddles are rotatably connected to the surface of the supporting rotating column.

The high-pressure atomizing nozzle is inclined to optimize the atomization effect of the material, promote contact with hot air, and prevent the material from sticking to the wall. The anti-sticking guide plates are set close to the tower wall to promote contact with hot air, prevent the material from sticking to the wall, guide the airflow to form a wall-mounted air curtain, optimize the direction of airflow and material movement, and enhance the anti-sticking effect.

[0011] As a further improvement of this invention: control jackets are fixedly connected to the surfaces of both the activation tank and the horizontal fermentation tank. A heating element and a temperature sensor are housed within the control jacket located on the surface of the activation tank, and the heating element and the temperature sensor are electrically connected.

[0012] Temperature sensors monitor the temperature inside the activation tank in real time, providing accurate temperature data for the heating element and enabling real-time control of the temperature inside the activation tank.

[0013] The heating element automatically adjusts the heating power based on the temperature sensor feedback to maintain a stable temperature inside the activation tank, creating a suitable environment for the activation reaction of biological pesticides and ensuring that the reaction proceeds efficiently and stably.

[0014] The heating element is electrically connected to the temperature sensor, which lays the foundation for automated temperature control of the activation tank, facilitates integration into the intelligent production system, and improves production efficiency and product quality consistency.

[0015] The jacket on the surface of the activation tank is from AiShengke, with models such as a-pgr-h-10. The jacket on the surface of the horizontal fermenter is from Shanghai Bailun Biotechnology Co., Ltd.: BLBIO-300SJ, with a jacket design pressure of 0.3 MPa.

[0016] The horizontal fermenter is fixedly connected to multiple water supply pipes, each equipped with a flow regulating valve. The design of the water supply pipes and flow regulating valves ensures precise humidity regulation, optimizes fermentation conditions, and enhances production stability.

[0017] As a further improvement of this utility model: Two air supply pipes are connected to the air inlet on one side and the air outlet on the other side of the combined drying tower. A converter fan is fixedly connected to one end of each of the two air supply pipes, and the converter fan is equipped with a speed adjustment knob. The converter fan is a Jiangsu Haoguan Environmental Protection Technology Co., Ltd. model: RHG910-7H2, with a power of 12.5KW. It features stable operation, low noise, and energy saving, and can be used in high-temperature fermentation tanks and other similar applications.

[0018] The switching fan balances the airflow at the inlet and outlet of the combined drying tower through the wind speed adjustment knob, avoids airflow short circuit, maintains stable pressure and reasonable flow field inside the tower, and ensures a suitable drying environment.

[0019] It can flexibly adjust the wind speed according to the material characteristics and drying process to adapt to different drying needs, ensure drying quality, and improve system stability and equipment service life.

[0020] As a further improvement of this invention: a supporting cooling bed is fixedly connected to the bottom of the combined drying tower, and a vibrating fluidized bed is installed inside the supporting cooling bed. The vibrating fluidized bed is connected to the supporting cooling bed via springs. Shandong Longxing Chemical Machinery Group Co., Ltd. may launch the LX-LCB-2000 model supporting cooling bed. This model is suitable for the post-drying treatment of large-volume biological pesticides, with a processing capacity of approximately 2000 kg / h. It is made of high-quality steel, has a robust structure, and can stably support the material falling from the combined drying tower, achieving rapid material cooling and realizing material fluidization and screening as described in this solution.

[0021] As a further improvement of this utility model: a spare exhaust pipe is connected to the surface of the combined drying tower at a position parallel to the air inlet and the air outlet, and a control valve is installed on the spare exhaust pipe, which is an electromagnetic valve.

[0022] The backup exhaust pipe can deal with emergencies. When the air inlet or outlet is blocked or affected by abnormal airflow, the solenoid valve is opened to provide an additional exhaust path, maintain airflow circulation in the tower, and prevent production interruption.

[0023] By adjusting the opening of the solenoid valve, the ventilation volume can be flexibly adjusted to meet the ventilation requirements of materials at different drying stages, thereby improving drying efficiency and product quality.

[0024] The backup exhaust duct enhances equipment reliability and safety, reduces the risk of ventilation failure, promptly removes hazardous substances, and ensures the safety of production personnel and equipment.

[0025] Compared with the prior art, this utility model provides a biological pesticide production device, which has the following beneficial effects:

[0026] 1. In this invention, after pesticides are discharged through the top feed pipe of the activation tank, the enamel layer inside the activation tank forms a corrosion-resistant barrier due to its smooth and dense surface characteristics, preventing the material from eroding and adhering to the tank wall during the reaction process. The carrier net is kept in a stable tension state by the top suspension structure, evenly bearing the material on the net surface, achieving the effect of preventing adhesion and corrosion and stable bearing during the material activation process. Subsequently, through the coordinated design of the inclined blade agitator, longitudinal guide plate and control jacket of the horizontal fermentation tank, combined with the precise supply of water and gas pipes, uniform stirring and constant temperature and humidity environment are ensured during material fermentation. When the horizontal fermentation tank is operating, the inclined blade agitator rotates at a set speed to stir the material, and the longitudinal guide plate guides the material to form a circulating flow to prevent... Localized accumulation and control jacketing regulate the tank temperature in real time through media circulation. Water and oxygen are precisely supplied via water supply and gas supply pipes according to fermentation parameters, ensuring uniform mixing and a constant temperature environment for material fermentation. Then, a combined drying tower employs a coordinated design of high-pressure atomizing nozzles, anti-sticking guide plates, and air inlets to achieve rapid atomization drying, anti-sticking, and optimized airflow. During operation, the high-pressure atomizing nozzles pressurize and atomize the material into tiny droplets, increasing the contact area with the hot airflow. The anti-sticking guide plates adhere to the tower wall, guiding the airflow to form a wall-mounted air curtain, preventing droplets from adhering to the tower wall. The air inlet introduces hot air at a set angle, ensuring full contact with the atomized material in the opposite direction, achieving efficient drying and anti-sticking effects.

[0027] The above description demonstrates that this device facilitates efficient production through a reasonable and compact continuous processing design, while effectively freeing up manpower and reducing production costs throughout the process while ensuring a reasonable process.

[0028] 2. This utility model achieves precise material delivery and process connection between processing units through the linkage control design of the conveying pipe and the control valve during operation.

[0029] Materials are conveyed in the conveying pipe along a preset path. The control valve automatically adjusts its opening and closing degree based on the material level and flow data fed back by the sensor, accurately controlling the amount of material passing through per unit time, and realizing precise quantitative conveying of materials between each processing stage.

[0030] The transmission combination design of the drive motor, coupling and support shaft provides stable power to the agitator, realizing efficient operation of material mixing.

[0031] If airflow fluctuations occur during the drying process, the air pressure inside the tower can be adjusted by switching fans. The backup exhaust pipe can be activated when the exhaust port is abnormal, ensuring the continuous operation of the drying process.

[0032] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Example c: Reference Figures 1 to 5 A specific embodiment of a biological pesticide production device, supporting base 1 structure

[0042] Made of robust and durable carbon steel and crafted using professional welding techniques, the support base 1 undergoes a rust-proofing treatment to extend its service life. Its shape and dimensions are designed based on the actual conditions of the production site and the layout requirements of each production piece of equipment, providing stable and reliable support for the entire biopesticide production unit and ensuring the stability of all equipment during efficient operation.

[0043] Control Cabinet 2 Structure

[0044] Mounted in a specific area atop the support base 1, the cabinet is constructed from cold-rolled steel plate, providing excellent protection for internal components. The control cabinet 2 is equipped with a high-performance programmable logic controller (PLC) and related circuit modules. The PLC has a pre-programmed intelligent control program specifically designed for the biopesticide production process. This program can precisely control various operating parameters of the activation tank 301, horizontal fermentation tank 302, and combined drying tower 303, such as temperature, humidity, stirring speed, and ventilation. It can also automatically coordinate the working rhythm between different devices according to preset production process logic. For example, after the activation tank 301 completes the activation reaction, the feeding program of the horizontal fermentation tank 302 is automatically triggered, eliminating the need for frequent manual intervention and significantly reducing manpower. The control cabinet 2 features a display screen and operation buttons on the front, allowing operators to monitor the production status and adjust parameters in real time. Furthermore, the control cabinet 2 has fault diagnosis and early warning functions. In case of equipment malfunction, it can promptly issue an alarm and indicate the cause of the fault, facilitating rapid problem location by maintenance personnel, reducing equipment downtime, and further lowering production costs.

[0045] The structure of the activation tank 301 in processing component 3;

[0046] Tank Structure: The main body of activation tank 301 is made of 304 stainless steel, forming a cylindrical tank with excellent pressure resistance and corrosion resistance. Inside the tank, at a specific height, two racks are securely welded to support the material reaction. These racks are made of a corrosion-resistant alloy, and each rack contains two carrier meshes 307 woven from a specific ratio of polypropylene, polyester fiber, and ceramic fiber. The mesh openings of the carrier meshes 307 are carefully designed to provide an ideal reaction space for biopesticide activation, facilitating full contact between the liquid material and the microorganisms or active substances on the carrier meshes 307. This design allows the activation reaction to proceed efficiently within a relatively small space, reducing material waste and lowering production costs.

[0047] Enamel Protective Layer: An enamel layer 308 is applied to the inner wall area of ​​the activation tank 301 corresponding to the upper and lower parts of the support frame using a hot-enameling process. This enamel layer 308 has an extremely smooth surface, effectively preventing bile-like liquid materials from adhering to the tank wall and avoiding oxidation reactions between the materials and the metal inner wall. This ensures the activation reaction takes place in a stable and pure environment. A stable reaction environment helps improve the success rate of the reaction and reduce the defect rate, thereby ensuring the rationality of the production process and indirectly reducing production costs.

[0048] Temperature Control System: A control jacket 320 is tightly fitted to the outside of the activation tank 301. The jacket is constructed of double-layered stainless steel plates, with a channel for fluid circulation formed in the middle. U-shaped resistance heating wires are evenly arranged inside the jacket, and a high-precision temperature sensor is installed at the center of the activation tank 301. The temperature sensor and heating wires are connected to the temperature control module inside the control cabinet 2 via a high-temperature resistant cable. When the temperature sensor detects a deviation from the set value in the tank temperature, the temperature control module automatically adjusts the heating wire current to precisely maintain a constant temperature inside the tank, creating suitable temperature conditions for the activation reaction of the liquid material. The control jacket 320 of the activation tank 301 uses a compatible model from AiShengke, which has excellent insulation performance and effectively reduces heat loss. Precise temperature control not only improves the efficiency of the activation reaction but also ensures that the reaction proceeds according to the preset process, reducing production instability caused by temperature fluctuations and thus reducing manpower investment in temperature monitoring and adjustment.

[0049] Structure of horizontal fermenter 302 in processing component 3

[0050] Stirring Drive Mechanism: The horizontal fermenter 302 is made of 316L stainless steel and is a horizontal cylindrical shape. The end caps at both ends of the tank are connected to the tank body via flanges. A supporting rotating column 309 is installed internally, supported at both ends by suitable bearings to ensure smooth and stable rotation. Multiple sets of inclined blade stirring paddles 310 are welded to the surface of the rotating column. Each set of paddles consists of several blades set at a specific angle and is made of high-strength stainless steel. The supporting rotating column 309, located near the activation tank 301, is connected to a three-phase asynchronous motor via a coupling. The motor is mounted on a bracket on the outside of the tank body, providing power for stirring and driving the stirring paddles to rotate. This ensures that the liquid material from the activation tank 301 is thoroughly mixed with the microorganisms and nutrients required for fermentation, promoting the fermentation reaction. This efficient stirring system allows the fermentation reaction to be completed in a shorter time, improving production efficiency and reducing reliance on manual stirring during the fermentation process.

[0051] Flow guiding structure: Multiple longitudinal flow guide plates (314 stainless steel) are welded and fixed to the lower surface of the fermenter's inner wall. These flow guide plates are set at a carefully designed inclination angle to change the flow direction of the liquid materials during stirring, optimizing the stirring effect, making the materials more evenly mixed, reducing dead zones, and improving fermentation efficiency. This reasonable flow guiding structure further ensures the effectiveness of the fermentation process, guarantees the stability of the fermentation process, reduces product quality problems caused by uneven fermentation, and thus reduces the cost of handling defective products and labor input.

[0052] Material conveying and humidity control: A set of conveying pipes 304 are connected to each side of the fermenter. One conveying pipe 304 introduces the activated liquid material from the activation tank 301, while the other conveys the fermented liquid material to the combined drying tower 303. The conveying pipes 304 are made of food-grade stainless steel, and their diameter is designed according to the material flow rate. A self-priming pump 305 is installed in the middle of the conveying pipe 304. The self-priming pump 305 is selected according to actual conveying requirements to provide sufficient power for the liquid material conveying. In addition, multiple water supply pipes 321 are installed on the top of the fermenter, each equipped with an electric regulating valve. The opening of the electric regulating valve is controlled by the signal from the humidity sensor in the control cabinet 2 to precisely regulate the humidity inside the tank, meeting the humidity requirements of the fermentation process. The control jacket 320 on the surface of the horizontal fermenter 302 is a compatible model from Shanghai Bailun Biotechnology Co., Ltd., and its design pressure can meet the pressure change requirements during the fermentation process. The automated material conveying and humidity control system eliminates the need for frequent manual operation, ensuring the precision of the fermentation process while freeing up manpower and reducing labor costs.

[0053] The combined drying tower 303 in processing component 3 has the following drying structure: The main body of the combined drying tower 303 is made of carbon steel and lined with a high-temperature resistant ceramic coating to adapt to the high-temperature environment during the drying process. A high-pressure atomizing nozzle 315 is installed at the top of the tower. Liquid materials transported from the horizontal fermenter 302 are sprayed out from the nozzle under pressure, instantly transforming into droplets, greatly increasing the contact area with hot air and accelerating the drying process. An air inlet 316 is located on one side of the lower part of the tower, and an exhaust outlet 317 is located on the other side. The air inlet 316 is connected to a hot air blower, which sends heated air into the tower to provide the necessary heat for drying the droplet-shaped materials. An induced draft fan is installed at the exhaust outlet 317 to discharge moisture and waste gas generated during the drying process. Two anti-sticking guide plates 318, made of stainless steel with a smooth surface, are installed on the inner wall of the tower opposite the air inlet and exhaust outlets 317. The baffle plate guides hot air along the tower wall, preventing material from sticking and ensuring uniform drying of the droplets within the tower, ultimately forming a solid biopesticide product. A discharge port 319 is located at the bottom of the tower, through which the dried solid biopesticide is transported to the subsequent packaging process via a discharge pipe. This highly efficient drying system significantly shortens drying time and improves production efficiency. Simultaneously, precise drying control ensures product quality, reduces product loss due to improper drying, and lowers production costs.

[0054] Ventilation and Cooling: Air inlet 316 and exhaust outlet 317 are connected to two air supply pipes 323, the other ends of which are connected to a converter fan 324. The converter fan 324 is selected based on its stable operation, low noise, and energy-saving characteristics. The fan is equipped with a speed adjustment knob, allowing operators to manually adjust the speed according to material characteristics and different drying stages. A supporting cooling bed 6 is installed below the tower. The main body of the cooling bed is a carbon steel frame structure, with a vibrating fluidized bed 7 installed inside. The vibrating fluidized bed 7 is connected to the supporting cooling bed 6 via springs 8. When the dried solid biopesticide falls from the outlet 319 into the supporting cooling bed 6, the vibrating fluidized bed 7 vibrates under the action of springs 8, causing the material to fluidize on the bed surface, achieving rapid cooling and preliminary screening to ensure uniform particle size, facilitating subsequent packaging or further processing. This intelligent ventilation and cooling system not only improves the efficiency of post-drying processing but also reduces manual operation in the cooling and screening stages, lowering labor costs.

[0055] Backup exhaust structure: A backup exhaust pipe 4 is connected to the side of the combined drying tower 303, parallel to the air inlet 316 and exhaust outlet 317. A solenoid valve is installed on the backup exhaust pipe 4. During normal production, the solenoid valve is closed. When the air inlet 316 or exhaust outlet 317 is blocked, or when abnormal airflow affects exhaust, the operator can open the solenoid valve. The backup exhaust pipe 4 provides an additional exhaust channel, maintaining airflow circulation within the tower and preventing production interruptions. Simultaneously, at different stages of the drying process, the operator can flexibly adjust the ventilation volume by adjusting the opening of the solenoid valve, optimizing the drying process and improving drying efficiency and product quality. The backup exhaust pipe 4 enhances the reliability and safety of the equipment, reduces the risk of ventilation failures, minimizes losses due to production interruptions, ensures the safety of production personnel and equipment, and further reduces production costs.

[0056] 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.
