Description

Technical Field

[0001] This utility model relates to the field of soil remediation microbial agent production technology, specifically a drying device for secondary salinization soil remediation microbial agents. Background Technology

[0002] The drying device for secondary salinization soil remediation microbial agents is a specialized drying equipment developed for salt-tolerant remediation microbial agents. Its core function is to rapidly reduce the moisture content of the microbial agent in a low-temperature environment while preserving the activity of the microbial strain to the greatest extent and avoiding the accumulation of salt during the drying process, which would affect the remediation efficiency. It is adapted to the special requirements of microbial agent stability in secondary salinization soil remediation scenarios.

[0003] The secondary salinization soil remediation microbial agent drying device includes a feeding module, a drying host, a temperature control system, an air distribution and dehumidification module, and a discharging module. These components work together to achieve "low-temperature drying + activity protection." The feeding module uses a spiral feeding structure to uniformly deliver the microbial agent to the drying host, avoiding accumulation. The drying host features a double-layer insulation cylinder design. The inner layer is a corrosion-resistant stainless steel cylinder with a built-in low-speed stirring paddle to prevent clumping, while the outer layer is filled with insulation cotton to reduce heat loss. The temperature control system monitors the temperature inside the cylinder in real time through multiple temperature sensors and dynamically adjusts the output of the heating unit to avoid localized overheating. The dehumidification module simultaneously extracts humid and hot air from inside the cylinder to reduce the migration and accumulation of salt with water vapor. Traditional drying devices for secondary salinization soil remediation microbial agents use single-point air intake or simple air distribution plate structures, resulting in chaotic airflow organization within the drying chamber, with eddies and dead zones. This causes inconsistent temperatures and air velocities to the microbial agent particles in different areas, leading to some particles becoming inactive due to overheating, while others clump together due to incomplete drying. Ultimately, this results in significant differences in the number of viable bacteria and uneven moisture content in the finished product, leading to unstable product quality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing drying devices for secondary salinized soil remediation microbial agents use single-point air intake or simple air distribution plate structure, which leads to chaotic airflow organization in the drying chamber, the existence of eddies and dead corners, and the inconsistent temperature and wind speed of the remediation microbial agent particles, affecting the drying quality.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A drying device for secondary salinization soil remediation bacterial agent includes a reaction tower, a first mounting base coaxially mounted on the reaction tower, an air inlet pipe mounted on the first mounting base, a first slot and a second slot respectively opened inside the first mounting base, one end of the air inlet pipe communicating with the first slot, a through groove opened at the bottom of the inner part of the first slot, a plurality of air outlet holes opened on the first mounting base, the air outlet holes respectively communicating with the second slot, a spiral coil coaxially mounted inside the first slot, and a heating ring coaxially mounted inside the spiral coil. When the rotating coil is connected to an alternating current, it can heat the heating ring. A fan is installed on the reaction tower. The air outlet of the fan is connected to the other end of the air inlet pipe. When the fan is started, it can deliver air into the first slot, so that the air comes into contact with the heating ring and is heated. Then it enters the second slot through the through slot and is sprayed out obliquely downward through several air outlets. A second mounting base is coaxially installed on the reaction tower. A rotating shaft is coaxially installed on the second mounting base. A propeller blade is installed on the rotating shaft. A drive assembly is installed on the second mounting base. When the drive assembly drives the rotating shaft and the propeller blade to rotate, the propeller blade stirs the repair agent.

[0006] The beneficial effects of this utility model are as follows: By setting up a first mounting base, a fan, a rotating shaft, a propeller blade, an air outlet, a first slot, a second slot, a spiral coil, a heating ring, and a through slot, air can be delivered into the first slot by starting the fan. When the spiral coil is connected to an alternating current, the heating ring can be heated, so that the air comes into contact with the heating ring and is heated before entering the second slot through the through slot. Then, it is sprayed out obliquely downward through several air outlets. Under the reaction force, the airflow forms an upward airflow inside the reaction tower. The propeller blade rotates and stirs the deposited bacterial agent, improving the fluidity of the bacterial agent particles, thereby improving the uniformity of contact between the warm airflow and the bacterial agent and improving the drying quality.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, a grid mesh is coaxially mounted on the second mounting base. The grid mesh is mesh-shaped and is fixedly connected to the second mounting base to form an integral structure. The grid mesh supports and limits the microbial agent, thereby increasing the microbial agent's air retention time.

[0009] Furthermore, several round rods are installed on the second mounting base, and several fan blades are coaxially mounted on the round rods. Several spheres are woven on both sides of the fan blades. When the fan blades are driven to rotate by wind power, the spheres collide with the grid mesh, which improves the convenience of grid mesh vibration.

[0010] Furthermore, the drive assembly includes a servo motor coaxially mounted on a second mounting base. The output end of the servo motor is fixedly connected to the rotating shaft, and starting the servo motor drives the rotating shaft and propeller blades to rotate.

[0011] Furthermore, an end cap is installed on the reaction tower, and a feed pipe is installed on the end cap. One end of the feed pipe passes through the end cap, and a first valve is installed on the feed pipe to control the opening and closing of the feed pipe.

[0012] Furthermore, an exhaust pipe is installed on the end cap, one end of which penetrates the end cap. A screen is installed inside the exhaust pipe, and a dispersion disc is coaxially installed on the end cap. The dispersion disc is conical in shape.

[0013] Furthermore, the bottom of the reaction tower is funnel-shaped, and a discharge pipe is installed at the bottom of the reaction tower. A second valve is installed on the discharge pipe to control the opening and closing of the discharge pipe.

[0014] Furthermore, a connecting seat is fixedly connected to the first mounting base, and the connecting seat has several threaded holes.

[0015] The beneficial effects of adopting the above-mentioned further scheme are as follows: by setting up a grid, the grid is designed to increase the contact area of ​​the microbial agent. The friction between the grid and the microbial agent reduces the rising speed of the microbial agent, limits the rising height of the microbial agent, and increases the residence time of the microbial agent, thereby improving the drying stability and uniformity. By setting up round rods, fan blades, and spheres, when the blower is started and an upward airflow is generated inside the reaction tower, the airflow drives the fan blades to rotate, causing the spheres to collide and rotate with the grid, causing the grid to vibrate and shake off the microbial agent in the gaps of the grid, thereby improving the stability of airflow.

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] like Figure 1-6As shown, a drying device for secondary salinization soil remediation microbial agents includes a reaction tower 1, which has a double-layer structure. The inner liner of the reaction tower 1 is made of stainless steel with a smooth surface, and the outer layer of the reaction tower 1 is filled with insulation cotton to reduce heat loss. A first mounting base 2 is coaxially mounted on the reaction tower 1. A connecting base 14 is fixedly connected to the first mounting base 2 by welding. The connecting base 14 has several threaded holes and is bolted to the reaction tower 1. An air inlet pipe 5 is welded onto the first mounting base 2 to allow air circulation. The first mounting base 2 has a first slot 15 and a second slot 16 inside. One end of the air inlet pipe 5 is connected to the first slot 15. A through groove 19 is formed at the bottom of the inner part of the first slot 15. The device 2 has several air outlets 13, which are symmetrically distributed and open downwards. Each air outlet 13 is connected to a second slot 16. A spiral coil 17 is coaxially mounted inside the first slot 15, and a heating ring 18 is coaxially mounted inside the spiral coil 17. The heating ring 18 is made of metal and is cylindrical. Several slots are formed on the heating ring 18 to allow air circulation and increase the contact area with the air. When an alternating current is applied to the spiral coil 17, it heats the heating ring 18. When the alternating current passes through the spiral coil 17, a rapidly changing magnetic field is generated. Eddy currents are induced inside the heating ring 18 within this magnetic field. Due to the resistance of the heating ring 18 itself, these powerful eddy currents overcome the resistance and flow rapidly. A large amount of Joule heat is generated, which rapidly heats the heating ring 18. A blower 4 is installed on the reaction tower 1. A filter canister is installed at the air inlet of the blower 4. A filter screen is installed inside the filter canister to filter the air. A pipe is installed at the air outlet of the blower 4 and is connected to the other end of the air inlet pipe 5. When the blower 4 is started, it can deliver air into the first slot 15, so that the air comes into contact with the heating ring 18 and is heated. Then it enters the second slot 16 through the through slot 19, and is sprayed out obliquely downward through several air outlets 13. A second mounting base 9 is coaxially installed on the reaction tower 1. A rotating shaft 10 is coaxially installed on the second mounting base 9. A propeller blade 11 is installed on the rotating shaft 10. A drive assembly is installed on the second mounting base 9. When the drive assembly drives the rotating shaft 10 and the propeller blade 11 to rotate, the propeller blade 11 stirs. The reaction tower 1 is equipped with an end cap 6 and a feed pipe 7. One end of the feed pipe 7 passes through the end cap 6 and is fitted with a first valve to control its opening and closing. The other end of the feed pipe 7 is connected to a screw conveyor to transport the remedial agent into the reaction tower 1. An exhaust pipe 8 is also installed on the end cap 6, with one end passing through the end cap 6. The exhaust pipe 8 is used to discharge steam and contains a screen to filter the agent. A conical dispersion disc 21 is coaxially mounted on the end cap 6 to disperse the transported raw materials. The bottom of the reaction tower 1 is funnel-shaped and is fitted with a discharge pipe 3, which is fitted with a second valve.The second valve controls the opening and closing of the discharge pipe 3, facilitating the discharge of the dried microbial agent. The system includes a first mounting base 2, a fan 4, a rotating shaft 10, a propeller blade 11, an air outlet 13, a first slot 15, a second slot 16, a spiral coil 17, a heating ring 18, and a through-slot 19. Starting the fan 4 delivers air into the first slot 15. When the spiral coil 17 is connected to an alternating current, it heats the heating ring 18. The heated air then enters the second slot 16 through the through-slot 19 and is ejected diagonally downwards through several air outlets 13. The airflow, under reaction force, forms an upward airflow inside the reaction tower 1. The rotating propeller blade 11 stirs the deposited microbial agent, improving the fluidity of the agent particles and thus enhancing the uniformity of contact between the warm airflow and the microbial agent, thereby improving the drying quality.

[0019] like Figure 2-6 As shown, a grid 12 is coaxially mounted on the second mounting base 9. The grid 12 is mesh-shaped and is fixedly connected to the second mounting base 9 to form an integral structure. The grid 12 is mesh-shaped to increase the contact area of ​​the microbial agent. The friction between the grid 12 and the microbial agent reduces the rising speed of the microbial agent, limits the rising height of the microbial agent, and increases the residence time of the microbial agent, thereby improving the drying stability and uniformity.

[0020] like Figure 6 As shown, several round rods 22 are installed on the second mounting base 9. Several fan blades 23 are coaxially installed on the round rods 22. Several spheres 24 are woven on both sides of the fan blades 23. With the round rods 22, fan blades 23 and spheres 24 set up, when the blower 4 starts and the reaction tower 1 generates an upward airflow, the airflow drives the fan blades 23 to rotate, causing the spheres 24 to collide with the grid 12 and rotate, causing the grid 12 to vibrate and shake off the bacterial agent in the gaps of the grid 12, thereby improving the stability of the airflow.

[0021] like Figure 5-6 As shown, the drive assembly includes a servo motor 20 coaxially mounted on the second mounting base 9. The output end of the servo motor 20 is fixedly connected to the rotating shaft 10. A protective cover is fitted on the servo motor 20 to protect the motor. Starting the servo motor 20 drives the rotating shaft 10 and the propeller blade 11 to rotate.

[0022] In practical use, this invention can also use a synchronous belt and synchronous pulley to replace the direct connection between the servo motor 20 and the rotating shaft 10. The synchronous pulleys are coaxially installed on the output end of the servo motor 20 and the rotating shaft 10, respectively. The two synchronous pulleys are located on the same plane, and a synchronous belt is installed on the synchronous pulley. By starting the servo motor 20, the rotating shaft 10 is driven to rotate, which drives the propeller blade 11 to rotate and stir the soil remediation agent at the bottom of the reaction tower 1, thereby improving the fluidity of the agent.

[0023] Working principle: When using this type of secondary salinization soil remediation bacterial agent drying device, the operator first connects an external power supply and feeds the soil remediation bacterial agent into the reaction tower 1 through the feed pipe 7. After the agent falls onto the dispersion plate 21, it is evenly dispersed along the dispersion plate 21, improving the uniformity of the agent distribution. It falls through the grid 12 and air can be delivered into the first slot 15 by starting the fan 4. When the alternating current is connected through the spiral coil 17, the heating ring 18 is heated, so that the air comes into contact with the heating ring 18 and is heated before entering the second slot 15 through the through slot 19. The second slot 16 is then sprayed out obliquely downwards through several air outlets 13. Under the reaction force, the airflow forms an upward airflow inside the reaction tower 1. The propeller blades 11 rotate and stir the deposited microbial agent, improving the fluidity of the microbial agent particles, thereby improving the uniformity of contact between the warm airflow and the microbial agent and improving the drying quality. When the microbial agent rises under the action of the airflow, the microbial agent grid 12 isolates and limits the rising height of the microbial agent. The grid 12 has several mesh holes to increase the contact area of ​​the microbial agent, increase the dwell time, and improve the drying stability and uniformity.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
