Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a controlled-release fertilizer dryer. Background Technology

[0002] In order to better preserve controlled-release fertilizers during the production process, it is generally necessary to control the moisture content of the finished product. This requires an effective drying process during the production of controlled-release fertilizers to reduce the moisture content of the fertilizer, which can help preserve it better, reduce its weight, and facilitate transportation.

[0003] Current controlled-release fertilizer dryers use a circulating mechanism to circulate and lift the controlled-release fertilizer, and then use hot air to dry the lifted controlled-release fertilizer. However, this intermittent working method has low drying efficiency, and the contact position between the lifted controlled-release fertilizer and the hot air is not the same each time, resulting in uneven drying effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a controlled-release fertilizer dryer that has higher drying efficiency and more uniform drying effect for controlled-release fertilizers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a controlled-release fertilizer dryer, including a housing and a control cabinet, and further including a stirring mechanism and a blower mechanism;

[0006] The stirring mechanism includes a horizontal plate, a fixed cylinder, a rotating shaft, and a drive assembly. The horizontal plate is fixedly installed on the inner wall of the box. The fixed cylinder is fixedly installed on the horizontal plate along the longitudinal direction. The rotating shaft is arranged along the longitudinal direction in the box and is rotatably connected to the fixed cylinder. Multiple blades are fixedly installed on the outer circumferential surface of the rotating shaft. The drive assembly is used to control the rotation of the rotating shaft.

[0007] The blower mechanism includes blower pipes and a hot air blower. Multiple blower pipes are arranged horizontally above the blades and are fixedly connected to the fixed cylinder. The multiple blower pipes are arranged at intervals along the circumference of the fixed cylinder. The blower pipes are connected to the fixed cylinder. Multiple air outlets are opened at the bottom of the blower pipes. The hot air blower is electrically connected to the control cabinet. The air outlet of the hot air blower is connected to the fixed cylinder.

[0008] Furthermore, a cavity is formed inside the rotating shaft, a receiving groove is formed inside the blade, the receiving groove is connected to the cavity, and an exhaust port is opened at the top of the blade, the exhaust port is connected to the receiving groove.

[0009] Furthermore, a filter screen is fixedly installed on the inner wall of the exhaust port.

[0010] Furthermore, the drive assembly includes a first gear, a motor, and a second gear. The first gear is fixedly mounted on the rotating shaft, the motor is electrically connected to the control cabinet, and the second gear is fixedly mounted on the output shaft of the motor and meshes with the first gear.

[0011] Furthermore, the bottom of the box has a discharge port, and a discharge assembly is provided at the discharge port. The discharge assembly includes a discharge plate and a cylinder. The first end of the discharge plate is rotatably connected to the inner wall of the discharge port, the first end of the cylinder is hinged to the box, and the second end of the cylinder is hinged to the second end of the discharge plate.

[0012] Furthermore, the blades are made of aluminum.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a controlled-release fertilizer dryer in which a stirring mechanism and a blowing mechanism work together. The stirring mechanism stirs the controlled-release fertilizer in the chamber, resulting in more uniform stirring. Therefore, compared with existing methods that circulate and agitate the controlled-release fertilizer for drying, this utility model achieves a more uniform drying effect. During the stirring process, hot air is discharged through the air outlets on multiple blowing pipes to dry the controlled-release fertilizer, resulting in higher drying efficiency.

[0024] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0025] like Figures 1-6 As shown, this utility model provides a controlled-release fertilizer dryer, including a housing 10 and a control cabinet, as well as a stirring mechanism 20 and a blower mechanism 40.

[0026] The stirring mechanism 20 includes a horizontal plate 21, a fixed cylinder 22, a rotating shaft 23, and a drive assembly 30. The horizontal plate 21 is fixedly installed on the inner wall of the housing 10. The fixed cylinder 22 passes longitudinally through the horizontal plate 21 and is fixedly connected to the horizontal plate 21. The rotating shaft 23 is longitudinally disposed inside the housing 10 and rotatably connected to the fixed cylinder 22. The rotating shaft 23 is located below the fixed cylinder 22, and multiple blades 24 are fixedly installed on the outer circumferential surface of the rotating shaft 23. The multiple blades 24 are arranged at equal intervals along the circumference of the rotating shaft 23. The drive assembly 30 is used to control the rotation of the rotating shaft 23.

[0027] The blower mechanism 40 includes blower pipes 41 and a hot air blower. Multiple blower pipes 41 are arranged horizontally above the blades 24 and are fixedly connected to the fixed cylinder 22. The multiple blower pipes 41 are arranged at equal intervals along the circumference of the fixed cylinder 22 and are connected to the fixed cylinder 22. Multiple air outlets are opened at the bottom of the blower pipes 41 and are connected to the blower pipes 41. The hot air blower is placed on the ground and electrically connected to the control cabinet. The air outlet of the hot air blower is connected to the fixed cylinder 22 via a pipe 42.

[0028] The specific working process of this utility model is as follows: First, the operator adds controlled-release fertilizer into the chamber 10 using a feeding machine. Then, the control cabinet controls the drive assembly 30 and the hot air blower to start simultaneously. The drive assembly 30 drives the rotating shaft 23 to rotate, thereby causing multiple blades 24 to evenly stir the controlled-release fertilizer in the chamber 10. Compared with the existing method of circulating and lifting controlled-release fertilizer for drying, the subsequent drying effect of this utility model is more uniform. The hot air discharged from the hot air blower enters the air blowing pipe 41 through the pipe 42 and the rotating cylinder. During the stirring process, the hot air is discharged through the air outlets on multiple air blowing pipes 41 to dry the controlled-release fertilizer. Stirring and drying at the same time results in higher drying efficiency.

[0029] In one embodiment, a cavity is formed inside the rotating shaft 23. A receiving groove is formed inside the blade 24, which communicates with the cavity. An exhaust port 25 is opened at the top of the blade 24, which communicates with the receiving groove.

[0030] When the hot air blower is working, the hot air it exhausts also enters the receiving tank through pipe 42 and fixed cylinder 22, and is finally discharged from exhaust port 25. While the hot air is in the receiving tank, some of its heat is transferred to the controlled-release fertilizer through blades 24, thereby drying the controlled-release fertilizer and further improving drying efficiency.

[0031] In one embodiment, a filter screen 26 is fixedly installed on the inner wall of the exhaust port 25. During the process of adding controlled-release fertilizer to the housing 10, the filter screen 26 serves to isolate the fertilizer and prevent it from falling into the receiving tank.

[0032] In one embodiment, the drive assembly 30 includes a first gear 31, a motor 32, and a second gear 33. The first gear 31 is fixedly mounted on the rotating shaft 23. The motor 32 is fixedly mounted on the horizontal plate 21 and electrically connected to the control cabinet. The second gear 33 is fixedly mounted on the output shaft of the motor 32 and meshes with the first gear 31.

[0033] When the drive assembly 30 is working, the control cabinet controls the motor 32 to start, which in turn drives the first gear 31 to rotate. The first gear 31 then drives the second gear 33 to rotate, which in turn drives the rotating shaft 23 to rotate. This drive assembly 30 has a simple structure and is easy to produce and manufacture.

[0034] In one embodiment, the bottom of the housing 10 has a discharge port 11. A discharge assembly 50 is provided at the discharge port 11, which includes a discharge plate 51 and a cylinder 52. The first end of the discharge plate 51 is rotatably connected to the inner wall of the discharge port 11. The first end of the cylinder 52 is hinged to the housing 10, and the second end of the cylinder 52 is hinged to the second end of the discharge plate 51. The cylinder 52 is electrically connected to the control cabinet.

[0035] Initially, cylinder 52 is in an extended state, at which point discharge plate 51 just blocks discharge port 11. After drying is complete, the operator places the receiving box directly below discharge port 11, and then the control cabinet controls cylinder 52 to retract. At this time, the second end of discharge plate 51 will flip downward, and the controlled-release fertilizer in box 10 will fall into the receiving box. Meanwhile, stirring mechanism 20 continues to work, moving the controlled-release fertilizer in box 10 to discharge port 11 until all the controlled-release fertilizer in box 10 has fallen into the receiving box.

[0036] In one embodiment, the blade 24 is made of aluminum, which has excellent thermal conductivity, further improving drying efficiency.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
