Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical and fertilizer production and processing technology, and in particular to an integrated drying and cooling device for pharmaceutical and fertilizer production. Background Technology

[0002] Pesticide-fertilizer combination is a new type of agricultural input product that combines pesticides and fertilizers. It combines the pest and disease control functions of pesticides with the nutrient supply functions of fertilizers. By combining pesticides and fertilizers, it can fertilize and control pests and diseases in one application, reducing the number of field operations and labor input, and improving agricultural production efficiency. A reasonable pesticide-fertilizer formula can provide comprehensive nutrition to crops while controlling pests and diseases, promoting healthy crop growth, enhancing crop resistance, and making crops more resistant to adverse environmental effects.

[0003] In the production and processing of pesticide fertilizers, drying and cooling are required. The pesticide fertilizer materials enter the drying and cooling chamber through a conveying device and are placed on a drying and cooling tray or conveyor belt. The heating system is activated, and the heating elements generate heat to evaporate the moisture in the material. However, during the drying process, uneven distribution of hot air or inconsistent residence time of the material in the drying equipment can lead to some pesticide fertilizers being over-dried while others are under-dried. Existing solutions include optimizing the internal air duct design of the equipment, adding guide plates to promote uniform distribution of hot air, ensuring that all parts of the material can fully and evenly contact the airflow, and using variable frequency speed control technology to control the material conveying speed and ensure that the residence time of the material in the drying chamber is consistent. However, the drying and cooling processes still need to be carried out separately. In humid climates, the dried pesticide fertilizer can become wet again, which will affect the subsequent cooling process and thus the processing effect of the pesticide fertilizer. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a drying and cooling integrated device for fertilizer and pesticide production, comprising a fixed frame 1, a connecting frame 3 fixedly connected to the top wall of the fixed frame 1, and heating plates 4 fixedly connected to the front and rear sides of the connecting frame 3. The heating plates 4 heat and dry the fertilizer and pesticide inside the drying drum 5. The inner wall of the connecting frame 3 is fixedly connected to the drying drum 5, and a servo motor 6 is fixedly connected to the top wall of the drying drum 5. A rotating column 7 is fixedly connected to the output end of the servo motor 6, and stirring blades 8 are fixedly connected to the left and right sides of the rotating column 7. This allows the stirring blades 8 to stir the fertilizer and pesticide when the servo motor 6 is activated, thereby improving drying efficiency. A grooved plate 10 is fixedly connected to the bottom of the rotating column 7, reducing material blockage through the rotation of the grooved plate 10. An output valve 12 is fixedly connected to the bottom of the drying drum 5. A cooling tank 13 is fixedly connected to the bottom of the outer wall of the fixed frame 1. The outer wall of the cooling tank 13 is fixedly connected to the inner wall of the fixed frame 1. A water pump 14 is fixedly connected to the right side of the fixed frame 1. A connecting pipe 15 is connected to the right end of the water pump 14. When the water pump 14 is started, it draws water from the inside of the water tank 16 through the connecting pipe 15. The bottom end of the connecting pipe 15 is connected to the water tank 16. A mixing blade 17 is rotatably connected inside the water tank 16. A cooling pipe 18 is connected to the top of the water tank 16. Under the delivery of the water pump 14, the coolant can cool the cooling tank 13 through the cooling pipe 18, so as to achieve the purpose of cooling the fertilizer. The inner wall of the cooling pipe 18 is set on the outer wall of the cooling tank 13. A discharge valve 19 is fixedly connected to the bottom end of the cooling tank 13. An auxiliary mechanism 2 is set on the left side of the connecting frame 3. The auxiliary mechanism 2 is used to improve the drying efficiency of the fertilizer.

[0032] Specifically, by activating the servo motor 6, the rotating column 7 drives the stirring blades 8 to rotate, ensuring that the fertilizer and pesticide inside the drying tank 5 can be mixed evenly. As stirring proceeds, the heat output of the heating plate 4 ensures that heat can be effectively transferred to the fertilizer and pesticide, thereby achieving the effect of uniform mixing and drying. After the drying process is completed, the output valve 12 is opened, allowing the fertilizer and pesticide to enter the cooling tank 13. Then, the water pump 14 is started, allowing cooling water to be drawn from the water tank 16. This cooling water flows through the cooling pipe 18 to effectively cool the fertilizer and pesticide. After cooling, the internal heat of the fertilizer and pesticide is dissipated, while the coolant with heat returns to the water tank 16. In this process, the impact of the coolant on the mixing blades 17 increases the flow rate of the water, further enhancing the heat dissipation effect of the coolant. This completes the integrated drying and cooling process, effectively preventing the dried fertilizer and pesticide from absorbing moisture again in a humid environment, thereby improving the processing quality of the fertilizer and pesticide.

[0033] Reference Figure 1 , Figure 2 and Figure 5The auxiliary mechanism 2 includes a variable frequency fan 201. The right side of the variable frequency fan 201 is fixedly connected to the left side of the connecting frame 3. A heating device 202 is fixedly connected to the rear side of the top wall of the variable frequency fan 201. A filter column 203 is fixedly connected to the top wall of the heating device 202, so that when the variable frequency fan 201 is started, the airflow is filtered through the filter column 203. A heat-insulated conveying pipe 204 is connected to the front side of the top wall of the variable frequency fan 201. An annular nozzle 205 is connected to the top of the heat-insulated conveying pipe 204, so that the airflow is heated through the heating device 202. Then, the heated airflow is sprayed through the annular nozzle 205, which improves the drying effect of the fertilizer. The outer wall of the annular nozzle 205 is fixedly connected to the inner top wall of the drying barrel 5. An exhaust valve 207 is connected to the top of the rear side of the drying barrel 5.

[0034] Specifically, by starting the variable frequency fan 201, external air is drawn into the device and filtered through the filter column 203 to ensure that the airflow does not contain large dust particles and impurities. If these substances enter the drying barrel 5, they will negatively affect the drying process and may even damage the equipment inside the drying barrel 5. After the airflow is purified by the filter column 203, the heating device 202 begins to heat the purified airflow, which accelerates the evaporation of moisture in the fertilizer and improves the drying efficiency. The heated airflow is then transported through the insulated conveying pipe 204. The insulated conveying pipe 204 is designed to maintain the temperature of the airflow and prevent heat loss during transport. With the connection of the insulated conveying pipe 204, the heated airflow is finally sprayed into the interior of the drying barrel 5 through the annular nozzle 205, ensuring that the fertilizer and pesticide are thoroughly and evenly dried. The fertilizer and pesticide inside the drying barrel 5 are effectively dried, and the efficiency of the entire drying process is improved.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The auxiliary mechanism 2 includes a rubber ring 206, the inner wall of which is fixedly connected to the top of the outer wall of the heat-insulating conveying pipe 204, and the outer wall of which is fixedly connected to the left side of the drying barrel 5; a control switch 22 is fixedly connected to the right side of the connecting frame 3, and the control switch 22 is electrically connected to the servo motor 6, the water pump 14, the frequency converter fan 201 and the heating equipment 202 respectively; a sealing ring 11 is fixedly connected to the top of the outer wall of the discharge valve 19, and a protective ring 20 is fixedly connected to the right side of the water pump 14;

[0036] Specifically, the rubber ring 206 can protect the top connection of the heat-insulating conveying pipe 204. The control switch 22, which is electrically connected to the servo motor 6, water pump 14, variable frequency fan 201 and heating equipment 202 respectively, can turn the equipment on and off. The sealing ring 11 can improve the sealing effect between the discharge valve 19 and the bottom wall of the cooling tank 13.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Support columns 23 are fixedly connected to the four corners of the bottom wall of the fixed frame 1, and corner protectors 24 are fixedly connected to the bottom of the support columns 23; an observation window 21 is fixedly connected to the rear side of the fixed frame 1, and the rear side of the observation window 21 is designed to be smooth; two inclined rods 9 are fixedly connected to the inner walls of the two stirring blades 8, and the multiple inclined rods 9 are designed to be symmetrical.

[0038] Specifically, the connection between the support column 23 and the corner protector 24 improves the stability of the device, allows observation of the interior of the fixed frame 1 through the observation window 21, and increases the shearing force on the fertilizer through the diagonal bar 9, thereby improving the drying effect.

[0039] Working principle: At the start of use, the servo motor 6 is started, which causes the rotating column 7 to drive the stirring blade 8 to rotate, so that the fertilizer and medicine inside the drying tank 5 can be evenly mixed. The heat output of the heating plate 4 allows the heat to be transferred to the fertilizer and medicine, achieving a uniform mixing and drying effect. Then, with the opening of the output valve 12, the fertilizer and medicine enter the cooling tank 13. Then, with the start of the water pump 14, the cooling water is drawn from the water tank 16 and cooled through the cooling pipe 18. Then, the coolant carrying the heat returns to the water tank 16, which impacts the mixing blade 17, thereby increasing the water flow rate and improving the heat dissipation effect inside the coolant. Finally, the purpose of drying and cooling is achieved, which avoids the fertilizer and medicine being moistened again after drying, thus improving the processing quality.

[0040] Furthermore, by starting the variable frequency fan 201, the airflow is filtered through the filter column 203, preventing larger dust particles and impurities from entering the interior of the drying barrel 5. Subsequently, the airflow is heated by the heating device 202, and then, through the connection of the heat-insulated conveying pipe 204, the heated airflow can be introduced into the interior of the drying barrel 5 via the annular nozzle 205, thereby improving the drying effect of the fertilizer and increasing the drying efficiency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
