Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer drying equipment, and in particular to a fertilizer drying device for fertilizer production. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material bases of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional field energy concentrated organic fertilizers. After granulation, fertilizers still contain a large amount of water and vapor. If they are packaged directly, the fertilizer granules will clump together and even change color, affecting the quality of the fertilizer.

[0003] Currently, the drying methods commonly used in the industry are relatively simple, with blowers installed only at the edge of the conveyor belt. This method can only dry the surface of the fertilizer and cannot reach the moisture inside the fertilizer. Over time, the residual moisture inside the fertilizer will cause a large amount of fertilizer to clump together, which not only seriously affects the drying quality of the fertilizer, but also greatly reduces the overall work efficiency.

[0004] Therefore, it is essential to provide a fertilizer drying device for fertilizer production to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a fertilizer drying device for fertilizer production. In this invention, fertilizer enters the drying chamber through an inverted conical hopper. The drying machine radiates hot air from top to bottom. A motor drives a rotating adapter rod to rotate. Simultaneously, electric telescopic rods installed at both ends of the adapter rod extend and retract differentially, which can adjust the relative movement position and spacing of the two parallel electric telescopic columns. Furthermore, it can control the extension, retraction, and movement of the elastic telescopic rod between the two electric telescopic columns, driving the crushing blades to perform movable rotational motion. The longer crushing blades cut the central layer of the fertilizer, while the shorter crushing blades crush the edge clumps. After drying, the fertilizer is drawn into the fertilizer storage tank through a one-way valve by a suction pump that generates negative pressure. This invention can ensure the drying effect of the fertilizer and effectively improve the working efficiency of fertilizer drying operations.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A fertilizer drying device for fertilizer production is provided, including a drying chamber, a drying chamber inlet at the top of the drying chamber, a feeding hopper installed at the drying chamber inlet, a drying chamber outlet at the bottom of the drying chamber, a suction storage component installed at the drying chamber outlet, a tilting mechanism installed inside the drying chamber, and a baking machine installed on the top inner wall of the drying chamber.

[0008] Specifically, the flipping mechanism includes two motors, which are respectively installed on both sides of the drying chamber. Each motor has an adapter rod radially mounted on its output shaft, and electric telescopic rods are symmetrically mounted at both ends of each adapter rod. Two sets of adjustable positioning components are installed in parallel between the telescopic ends of the four electric telescopic rods.

[0009] Preferably, an elastic telescopic rod is installed between the two sets of adjustable positioning components. Three crushing blades are installed equidistantly on the elastic telescopic rod. The three crushing blades are installed alternately on the elastic telescopic rod. Among the three crushing blades, the two crushing blades closest to the two ends of the elastic telescopic rod are shorter, and the middle crushing blade is longer.

[0010] Each adjustable positioning assembly is installed between the telescopic ends of two parallel-installed electric telescopic poles. Each adjustable positioning assembly includes two electric telescopic columns, the fixed ends of which are respectively installed on the telescopic ends of the two parallel-installed electric telescopic poles.

[0011] A support block is installed between the telescopic ends of the two electric telescopic columns, and an elastic telescopic rod is installed between the two support blocks. The fixed ends of the four electric telescopic columns are respectively fixedly installed to the telescopic ends of the four electric telescopic rods.

[0012] The feed hopper has an inverted conical cross-section, and the bottom inner wall of the drying chamber has an arc surface structure. The bottom of the drying chamber is in movable contact with the adjustable positioning component.

[0013] The suction storage assembly includes a fertilizer storage tank, with a suction pump connected to the inlet of the fertilizer storage tank. A one-way valve is connected to the suction pump, and the one-way valve is connected to the outlet of the drying chamber.

[0014] This utility model includes a drying chamber with a suction storage assembly installed at the discharge port. A tilting mechanism is installed inside the drying chamber, and a baking machine is installed on the top inner wall of the drying chamber. Fertilizer enters the drying chamber through an inverted conical feed hopper. The baking machine radiates hot air from top to bottom. A motor drives a rotating adapter rod, and simultaneously, electric telescopic rods installed at both ends of the adapter rod extend and retract differentially. This allows adjustment of the relative movement and spacing of two parallel electric telescopic rods. Furthermore, it controls the extension, retraction, and movement of the elastic telescopic rod between the two electric telescopic rods, driving the crushing blades to perform movable rotational motion. The longer crushing blades cut the central layer of the fertilizer, while the shorter crushing blades crush the edge clumps. After drying, the fertilizer is sucked into a fertilizer storage tank by a suction pump. This utility model ensures the drying effect of the fertilizer and effectively improves the work efficiency of fertilizer drying operations. Attached Figure Description

[0041] like Figure 1-3 As shown, the flipping mechanism 6 includes two motors 8, which are respectively installed on both sides of the drying chamber 1. Each motor 8 has a radially mounted adapter rod 9 on its output shaft. Each adapter rod 9 has an electric telescopic rod 10 symmetrically mounted at both ends. Two sets of adjustable positioning components 11 are installed in parallel between the telescopic ends of the four electric telescopic rods 10.

[0042] like Figure 1-3 As shown, an elastic telescopic rod 12 is installed between the two sets of adjustable positioning components 11. Three crushing blades 13 are installed equidistantly on the elastic telescopic rod 12. The three crushing blades 13 are installed alternately on the elastic telescopic rod 12. Among the three crushing blades 13, the two crushing blades 13 closest to the two ends of the elastic telescopic rod 12 are shorter, and the middle crushing blade 13 is longer.

[0043] like Figure 1-3 As shown, each set of adjustable positioning components 11 is installed between the telescopic ends of two parallel electric telescopic rods 10. Each adjustable positioning component 11 includes two electric telescopic columns 14, and the fixed ends of the two electric telescopic columns 14 are respectively installed on the telescopic ends of the two parallel electric telescopic rods 10.

[0044] like Figure 1-3 As shown, a support block 15 is installed between the telescopic ends of the two electric telescopic columns 14, and an elastic telescopic rod 12 is installed between the two support blocks 15. The fixed ends of the four electric telescopic columns 14 are respectively fixedly installed with the telescopic ends of the four electric telescopic rods 10.

[0045] like Figure 1-3 As shown, the cross-section of the feed hopper 3 is an inverted cone, the bottom inner wall of the drying chamber 1 is an arc surface structure, and the bottom of the drying chamber 1 is in movable contact with the adjustable positioning component 11.

[0046] The suction storage assembly 5 includes a fertilizer storage tank 16. A suction pump 17 is connected to the inlet of the fertilizer storage tank 16. A one-way valve 18 is connected to the suction pump 17. The one-way valve 18 is connected to the outlet 4 of the drying chamber.

[0047] The motor 8 drives the adapter rod 9 to rotate the electric telescopic rod 10. The electric telescopic column 14 installed between the electric telescopic rods 10 controls the three-dimensional movement of the elastic telescopic rod 12, so that the long and short interlaced crushing blades 13 on the elastic telescopic rod 12 can perform multi-directional flipping and cutting of fertilizer. The electric telescopic column 14 controls the movement position of the support block 15 to adapt to fertilizer of different volumes. Vacuum suction is used to avoid material blockage at the outlet, and the one-way valve 18 prevents backflow.

[0048] The long and short interlaced crushing blades 13, driven by the elastic telescopic rod 12, cut and flip through the fertilizer in multiple directions. The electric telescopic rod 10 and the electric telescopic column 14 work together to realize the three-dimensional motion trajectory of the crushing blades 13, which comprehensively and quickly crushes the fertilizer clumps, thereby improving the drying efficiency after the fertilizer clumps are crushed.

[0049] In this invention, fertilizer enters the drying chamber 1 through the inverted conical feed hopper 3. The baking machine 7 radiates hot air from top to bottom. The motor 8 drives the adapter rod 9 to rotate. At the same time, the electric telescopic rods 10 installed at both ends of the adapter rod 9 extend and retract differentially, which can adjust the relative movement position and spacing of the two parallel electric telescopic columns 14. Furthermore, it can control the extension, retraction and movement of the elastic telescopic rod 12 between the two electric telescopic columns 14, driving the crushing blades 13 to perform movable rotational motion. The long crushing blades 13 cut the central layer of fertilizer, and the short crushing blades 13 crush the edge clumps. After drying, the fertilizer is drawn into the fertilizer storage tank 16 through the one-way valve 18 by the negative pressure generated by the suction pump 17. This invention can ensure the drying effect of fertilizer and effectively improve the working efficiency of fertilizer drying operation.
