Description

Technical Field

[0001] This utility model belongs to the field of fertilizer processing technology, specifically relating to a mixing device for slow-release fertilizer production that can improve the slow-release effect. Background Technology

[0002] The term "release" refers to the process by which nutrients are transformed from chemical substances into an effective form that plants can directly absorb and utilize. "Slow release" means that the release rate of chemical nutrients is much lower than the release rate of readily soluble fertilizers after they are applied to the soil and transformed into available nutrients for plants. Slow-release fertilizers have a longer fertilizer effect than uncoated fertilizers by more than 30 days, with reduced leaching and volatilization losses. The amount of fertilizer used can be reduced by 10-20% compared to conventional fertilization, achieving the goal of cost savings. They can be used in combination with readily soluble fertilizers as base fertilizer for one-time application, reducing fertilization labor by about one-third. They are also safe to use and prevent fertilizer damage. During the processing of slow-release fertilizers, the production of fertilizer coating needs to maintain a certain temperature to reduce organic pollution and increase film density. However, due to the long transportation distance, the temperature drops during transportation and cannot be kept stable, which affects the coating production and the quality of the finished product.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: including a screw extruder 1, a spiral mixing chamber 11, and a drive assembly 12. A first temperature measuring point sensor assembly 13 and a second temperature measuring point sensor assembly 14 are provided on one side of the spiral mixing chamber 11. Two connecting frames 2 are movably connected to the screw extruder 1. Several heating components 21 are connected between the two connecting frames 2. A control assembly 22 is connected to the top of the two connecting frames 2. Connecting grooves 23 are provided at the four corners of one side of each connecting frame 2. A third temperature measuring point sensor assembly 24 and a fourth temperature measuring point sensor assembly 25 are respectively provided on one side of each connecting frame 2. A moving assembly 3 is provided on the screw extruder 1. The moving assembly 3 drives the connecting frames 2. The drive assembly 12, the first temperature measuring point sensor assembly 13, the second temperature measuring point sensor assembly 14, the heating components 21, the third temperature measuring point sensor assembly 24, and the fourth temperature measuring point sensor assembly 25 are all electrically connected to the control assembly 22 through wires.

[0020] In this embodiment: The fertilizer is processed by setting up a screw extruder 1, a spiral mixing chamber 11, and a drive assembly 12. A first temperature sensing component 13 and a second temperature sensing component 14 are installed on one side of the spiral mixing chamber 11 to measure the temperature at both ends of the spiral mixing chamber 11. Two connecting frames 2 are movably connected to the screw extruder 1, and several heating components 21 are connected between the two connecting frames 2. The connecting frames 2 assemble the heating components 21 and can move outside the spiral mixing chamber 11 to provide auxiliary heating at different positions of the spiral mixing chamber 11. A control component 22 is connected to the top of the two connecting frames 2, and connecting grooves 23 are provided at the four corners of one side of each connecting frame 2. The groove 23 allows the connecting frame 2 to slide on the spiral mixing chamber 11. A third temperature sensing component 24 and a fourth temperature sensing component 25 are respectively installed on one side of each connecting frame 2. These components measure the temperature at the position of the spiral mixing chamber 11 on one side of the connecting frame 2. A moving component 3 is installed on the screw extruder 1, which drives the connecting frame 2. The driving component 12, the first temperature sensing component 13, the second temperature sensing component 14, the heating component 21, the third temperature sensing component 24, and the fourth temperature sensing component 25 are all electrically connected to the control component 22 via wires. The control component 22 connects to an external control host and control panel. The plate controls the start and stop of the drive assembly 12, the first temperature sensing component 13, the second temperature sensing component 14, the heating assembly 21, the third temperature sensing component 24, and the fourth temperature sensing component 25, thereby controlling the device. When the screw extruder 1 processes the slow-release fertilizer, the slow-release fertilizer is mixed and conveyed through the spiral mixing chamber 11 and the drive assembly 12. Due to the certain length of the spiral mixing chamber 11, a temperature difference is generated at both ends of the spiral mixing chamber 11. The temperature at the initial conveying end of the spiral mixing chamber 11 is detected by the first temperature sensing component 13. During the processing, the spiral mixing chamber is monitored in real time by the third temperature sensing component 24, the fourth temperature sensing component 25, and the second temperature sensing component 14. When the temperature difference at different locations is too large, a signal is sent to the control component 22. The control component 22 controls the drive component 12 to stop conveying and simultaneously controls the electric telescopic rod 32 in the moving component 3 to move the connecting frame 2 and the heating component 21 to the heating position to assist in heating the slow-release fertilizer inside the spiral mixing chamber 11 to the standard temperature. After the temperature reaches the standard, the third temperature measuring point sensor component 24 and the fourth temperature measuring point sensor component 25 transmit temperature signals to the control component 22. The control component 22 controls the heating component 21 to be turned off and the drive component 12 to be started to continue conveying the fertilizer until the fertilizer processing is completed. During this process, whenever the temperature is too low, it is heated in time to ensure that it maintains the standard temperature when it is conveyed to the next equipment.

[0021] The mobile component 3 includes a mounting frame 31. An electric telescopic rod 32 is installed at one end of the inner cavity of the mounting frame 31, and a connecting cavity 33 is opened at the other end of the mounting frame 31. A movable rod 4 is slidably connected to the inner cavity of the connecting cavity 33, and a spring 41 is sleeved on the outside of the movable rod 4. By setting the mounting frame 31 as the overall support structure of the mobile component 3, one of the connecting rods 26 is driven by the electric telescopic rod 32, thereby driving the connecting frame 2 to slide on the spiral mixing chamber 11. The movable rod 4 and the spring 41 are connected to the other connecting groove 23, and the connecting frame 2 is driven to slide under the traction of the electric telescopic rod 32.

[0022] Both connecting frames 2 are connected to the bottom of a connecting rod 26. The two connecting rods 26 are fixedly connected to the output end of the electric telescopic rod 32 and one end of the movable rod 4, respectively. The connecting rods 26 are used to connect the connecting frame 2 and the movable component 3.

[0023] One end of the movable rod 4 is fixedly connected to a limiting block 42. The mounting frame 31 has an inner sliding groove 421 that matches the limiting block 42. The connecting cavity 33 is connected to the inner sliding groove 421. By setting the limiting block 42, the sliding position of the movable rod 4 is limited, preventing it from sliding completely out of the mounting frame 31.

[0024] Two connecting rods 231 are symmetrically installed at the top and bottom of the spiral mixing chamber 11. The connecting frame 2 is slidably connected to the connecting rods 231 through the connecting groove 23. By setting the connecting rods 231, the connecting frame 2 can slide on the connecting rods 231 through the connecting groove 23, thereby allowing several heating components 21 to slide flexibly.

[0025] Several heating components 21 are arranged around the outside of the spiral mixing chamber 11, and the two ends of the heating components 21 are fixedly connected to two connecting frames 2 respectively; the several heating components 21 are arranged around the outside of the spiral mixing chamber 11, which can uniformly heat the cooling section of the spiral mixing chamber 11.

[0026] The third temperature measuring point sensor component 24 and the fourth temperature measuring point sensor component 25 are fixedly connected to the connecting frame 2 on the adjacent side through the bracket. The first temperature measuring point sensor component 13 and the second temperature measuring point sensor component 14 are located at both ends of one side of the spiral mixing chamber 11. The third temperature measuring point sensor component 24 and the fourth temperature measuring point sensor component 25 are installed on one side of the two connecting frames 2 through the bracket, which facilitates the measurement of the temperature of the auxiliary heating section.

[0027] The working principle and usage of this utility model are as follows: When processing slow-release fertilizer in a screw extruder 1, the slow-release fertilizer is mixed and conveyed through a spiral mixing chamber 11 and a drive assembly 12. Due to the certain length of the spiral mixing chamber 11, a temperature difference is generated at both ends of the spiral mixing chamber 11. The temperature at the initial conveying end of the spiral mixing chamber 11 is detected by the first temperature measuring point sensor assembly 13. During the processing, the temperature at different positions of the spiral mixing chamber 11 is monitored in real time by the third temperature measuring point sensor assembly 24, the fourth temperature measuring point sensor assembly 25, and the second temperature measuring point sensor assembly 14. When the temperature difference is too large, a signal is sent to the control assembly 22 to control the process. Component 22 controls the drive component 12 to stop conveying, and at the same time controls the electric telescopic rod 32 in the moving component 3 to move the connecting frame 2 and the heating component 21 to the heating position to assist in heating the slow-release fertilizer inside the spiral mixing chamber 11 to the standard temperature. After the temperature reaches the standard, the third temperature measuring point sensor component 24 and the fourth temperature measuring point sensor component 25 transmit temperature signals to the control component 22. The control component 22 controls the heating component 21 to be turned off and the drive component 12 to be started to continue conveying the fertilizer until the fertilizer processing is completed. During this process, whenever the temperature is too low, it is heated in time to ensure that it maintains the standard temperature when it is conveyed to the next equipment.
