Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a device for uniform distribution of hot air circulation in a potassium sulfate dryer. Background Technology

[0002] Potassium sulfate is an important inorganic compound with wide applications in various fields of agriculture and industry. It is also a high-quality chlorine-free potassium fertilizer suitable for chlorine-sensitive economic crops such as tobacco, grapes, citrus, and tea. It can improve crop resistance, enhance fruit quality, and increase fruit sugar content, color, and taste. Drying equipment is required for the processing of potassium sulfate.

[0003] The drying process of potassium sulfate generates a large amount of dust. Existing dryers have poor dust removal efficiency, leading to dust overflow. This not only pollutes the production environment but also causes some product to be lost with the dust, reducing product yield. At the same time, dust accumulation inside the equipment affects its normal operation and service life. The current solution is to use high-efficiency dust removal equipment, such as pulse bag dust collectors and cyclone dust collectors, to effectively collect the dust generated during the drying process. Appropriate dust suction ports are also installed inside the dryer to ensure timely dust extraction, reducing dust accumulation and overflow. However, the traditional hot air circulation method used in dryers still results in insufficient contact between hot air and potassium sulfate material, low heat exchange efficiency, and hot air merely passing over the material surface. A large amount of heat energy is not effectively utilized, leading to prolonged drying time, increased energy consumption, and reduced drying effect. Utility Model Content

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 4 An embodiment of this utility model provides a hot air circulation uniform distribution device for a potassium sulfate dryer, including a base 1, a support frame 2 fixedly connected to the rear side of the top wall of the base 1, the support frame 2 can support and fix the processing barrel 3, the processing barrel 3 is fixedly installed on the top of the support frame 2, and adjustment mechanisms 4 are provided on both the left and right sides of the processing barrel 3. The adjustment mechanisms 4 can expand the output range of the drying airflow, a filter mechanism 5 is provided on the left end of the front side of the top wall of the base 1, and a stabilizing mechanism 7 is provided on the outer wall of the base 1.

[0032] The support frame 2 includes two fixed shells 401. The adjacent sides of the two fixed shells 401 are respectively connected to the left and right sides of the processing tank 3. Connecting plates 402 are fixedly connected to the inner walls of the two fixed shells 401 on opposite sides. An electric push rod 403 is rotatably connected to the bottom of one side of each connecting plate 402. The electric push rod 403 drives an adjusting plate 404. One end of the electric push rod 403 is rotatably connected to the adjusting plate 404. A rotating rod 405 is rotatably connected to the top of one side of the adjusting plate 404. However, the rotating rod 405... Under the displacement restriction of the 5 adjustment plates 404, the adjustment plates 404 can rotate around the rotating rod 405 as the axis, thereby achieving the purpose of guiding and conveying the drying airflow, thus expanding the drying range and ensuring the uniformity of drying. The outer wall of the rotating rod 405 is rotatably connected to the top of one side of the connecting plate 402. A drying component 406 is provided at the right end of the front side of the top wall of the base 1. The drying component 406 can complete the output of the drying airflow. A stirring component 407 is provided at the front side of the processing tank 3, and a connecting component 408 is provided at the top of the processing tank 3.

[0033] The drying assembly 406 includes a drying fan 4061. The bottom of the drying fan 4061 is fixedly connected to the right front end of the top wall of the base 1. The left rear end of the drying fan 4061 is connected to a heat insulation pipe 4062, so that the drying airflow can be input when the drying fan 4061 is started. The top walls of the two fixed shells 401 are fixedly installed with multi-hole nozzles 4063. The top end of the heat insulation pipe 4062 is connected to the front side of the left multi-hole nozzle 4063, so that the airflow can be output through the two multi-hole nozzles 4063. The top walls of the two multi-hole nozzles 4063 are connected to the same connecting pipe 4064 to achieve the purpose of drying potassium sulfate material.

[0034] Specifically, the support frame 2 is used to support and fix the processing tank 3. Two fixed shells 401 are respectively connected to the left and right sides of the processing tank 3. The connecting plate 402, whose inner wall is fixed to the side away from the other, provides the installation base for the adjustment mechanism 4. In the adjustment mechanism 4, the electric push rod 403, which is rotatably connected to the bottom of one side of the connecting plate 402, serves as a power source. After starting, it drives the adjustment plate 404, which is rotatably connected to one end, to move. The rotating rod 405, which is rotatably connected to the top of one side of the adjustment plate 404, has its outer wall rotatably connected to the top of one side of the connecting plate 402, which restricts the displacement of the adjustment plate 404, so that the adjustment plate 404 rotates about the rotating rod 405 as an axis. By changing the angle of the adjustment plate 404, the drying airflow is guided, thereby expanding the output range of the drying airflow and ensuring the uniform drying of the material in the processing tank 3. The drying assembly 406, located on the right side of the front of the top wall of the base 1, consists of a drying fan 4061, an insulation pipe 4062, a multi-hole nozzle 4063, and a connecting pipe 4064. The bottom of the drying fan 4061 is fixed to the base 1. After starting, it generates a drying airflow, which is transported through the insulation pipe 4062 connected to the rear end of the left side. The top of the insulation pipe 4062 is connected to the front of the multi-hole nozzle 4063 on the left side. The multi-hole nozzles 4063 installed on the top walls of the two fixed shells 401 output the drying airflow, and the top walls of the two multi-hole nozzles 4063 are connected through the connecting pipe 4064 to ensure that the drying airflow is evenly distributed, thereby achieving the drying treatment of potassium sulfate material in the treatment tank 3. In addition, the filter mechanism 5 on the left side of the front of the top wall of the base 1 is used to purify the airflow, and the stabilizing mechanism 7 on the outer wall ensures the stable operation of the device.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The filtration mechanism 5 includes a processing shell 501, the bottom wall of which is fixedly connected to the left side of the top wall of the base 1. This allows the filter plate 502 and multiple adsorption sponge columns 503 to be connected while the processing shell 501 is fixed. The left side of the processing shell 501 is connected to the filter plate 502. The extracted airflow first passes through the filter plate 502 to filter larger particles and impurities. Multiple adsorption sponge columns 503 are slidably installed on the top of the processing shell 501. The airflow is then dried by the multiple adsorption sponge columns 503, thereby reducing the energy consumption of the drying fan 4061. The right side of the processing shell 501 is connected to a conveying pipe 504. The right end of the conveying pipe 504 is connected to the front left side of the drying fan 4061, thus ensuring the cleanliness of the drying airflow. The filtration mechanism 5 also includes a rubber ring 505, the outer wall of which is fixedly connected to the right side of the processing shell 501.

[0036] Specifically, the filter plate 502 connected to the left side of the processing shell 501 first plays an interception role during the airflow extraction process, filtering and separating larger particles and impurities contained in the airflow, thus initially purifying the airflow. Multiple adsorption sponge columns 503 are installed on the top of the processing shell 501 using a sliding installation method. These adsorption sponge columns 503 utilize their porous structure and adsorption characteristics to dry the initially filtered airflow, removing moisture and reducing the energy consumption required by the subsequent drying fan 4061 to achieve the drying effect. The conveying pipe connected to the right side of the processing shell 501... 504, the filtered and dried airflow is delivered to the front left side of the drying fan 4061 to ensure that the airflow entering the drying fan 4061 is clean and dry, thereby improving drying efficiency and effect. In addition, the rubber ring 505 in the filter mechanism 5 has its outer wall fixed to the right side of the processing shell 501 to enhance the sealing of the connection between the processing shell 501 and the conveying pipe 504, etc., to prevent airflow leakage, ensure the stable operation of the entire filtration process, ensure the cleanliness and conveying efficiency of the drying airflow, and enable the drying fan 4061 to output the required drying airflow efficiently and stably.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The stirring assembly 407 includes a servo motor 4071. The outer wall of the stirring assembly 407 is fixedly connected to the front side of the processing tank 3. The output end of the servo motor 4071 is fixedly connected to a rotating column 4072. Multiple stirring blades 4073 are fixedly connected to the outer wall of the rotating column 4072. Multiple rectangular grooves 4074 are opened on one side of the stirring blades 4073. The communication assembly 408 includes a feed shell 4081. The bottom end of the feed shell 4081 is connected to the top of the processing tank 3. The bottom of the processing tank 3 is connected to a discharge shell 4082. A sealing ring 4083 is fixedly connected to the top of the outer wall of the discharge shell 4082.

[0038] Specifically, the servo motor 4071 is started to drive the rotating column 4072 and multiple stirring blades 4073 to rotate, thereby turning the potassium sulfate material and improving the drying efficiency. The material is fed into and collected through the feed shell 4081 and the discharge shell 4082. The sealing ring 4083 improves the sealing of the connection between the discharge shell 4082 and the processing tank 3.

[0039] Reference Figure 1 , Figure 2 and Figure 4 A control switch 6 is fixedly connected to the front side of the base 1. The control switch 6 is electrically connected to the electric push rod 403, the drying fan 4061 and the servo motor 4071 respectively. The stabilizing mechanism 7 includes multiple connecting seats 701. The adjacent sides of the multiple connecting seats 701 are fixedly connected to the outer wall of the base 1 respectively. A support column 702 is fixedly connected inside the connecting seat 701.

[0040] Specifically, the control switch 6, which is electrically connected to the electric push rod 403, the drying fan 4061, and the servo motor 4071 respectively, enables the equipment to be turned on and off. The connection between the connecting seat 701 and the support column 702 improves the lateral stability of the device during operation.

[0041] Working principle: The drying fan 4061 is fixed to the front right end of the base 1. After starting, it generates a drying airflow, which is delivered to the multi-hole nozzle 4063 on the top wall of the fixed shell 401 through the heat insulation pipe 4062 connected to the rear left side. The airflow is output through the two multi-hole nozzles 4063 and the connecting pipe 4064 to dry the potassium sulfate material in the treatment tank 3. After the electric push rod 403 is started, it drives the adjusting plate 404 through extension and retraction. Under the limiting action of the rotating rod 405, the adjusting plate 404 rotates around the rotating rod 405 as the axis, changing the angle to dry the multi-hole nozzle. The drying airflow output from head 4063 is guided to expand the coverage of the drying airflow. At the same time, the stirring component 407 on the front side of the processing tank 3 works synchronously to stir the potassium sulfate material, so that the material is evenly exposed to the drying airflow during the stirring process. The regulating mechanism 4 and the stirring component 407 work together to ensure that the drying airflow fully contacts the material, avoids heat energy waste, shortens the drying time, and improves drying efficiency. All parts work together to ensure that the drying process of potassium sulfate material is carried out efficiently, avoiding the situation where the drying time is prolonged due to the ineffective use of heat energy.

[0042] Furthermore, after the drying fan 4061 starts, it draws in outside air through the processing shell 501. The airflow first passes through the filter plate 502 connected to the left side of the processing shell 501. The filter plate 502 intercepts larger particles and impurities in the airflow, preventing them from entering the processing flow and avoiding contamination of the potassium sulfate material. The airflow, after preliminary filtration, continues to rise and passes through multiple adsorption sponge columns 503 slidably installed on the top of the processing shell 501. The adsorption sponge columns 503 utilize their porous structure and adsorption properties to absorb moisture in the airflow, reducing the humidity of the airflow and minimizing the heat generated by the subsequent heating airflow from the drying fan 4061. The required energy consumption is minimized. When the adsorption capacity of the adsorption sponge column 503 decreases, it can be pulled out from the top of the treatment shell 501 for replacement, continuously ensuring the airflow drying and purification effect. The conveying pipe 504 connected to the right side of the treatment shell 501 delivers the filtered and dried clean airflow to the front left side of the drying fan 4061. The rubber ring 505 installed on the right side of the treatment shell 501 enhances the sealing of the connection between the treatment shell 501 and the conveying pipe 504, preventing airflow leakage and providing clean and dry airflow for the drying fan 4061, ensuring the high efficiency and cleanliness of the potassium sulfate material drying process.

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.
