Description

Technical Field

[0001] This utility model relates to the field of microbial fertilizer production technology, and in particular to a granulation device for producing compound microbial fertilizer. Background Technology

[0002] Microbial fertilizers, also known as bio-fertilizers, inoculants, or microbial fertilizers, are a type of fertilizer product that uses the life activities of microorganisms as its core to enable crops to obtain specific fertilizer effects. Microbial fertilizers are generally in granular form, so specialized microbial fertilizer granulation equipment is required during the production process.

[0003] Currently used fertilizer granulators include roller extrusion granulators and cutting granulators. While both types can achieve continuous granulation, the fertilizer raw materials used for granulation require water and mixing to facilitate subsequent fertilizer forming. This can lead to granulation particles sticking together, ultimately affecting the quality of the fertilizer output. Furthermore, cutting granulators are inconvenient to clean after each use, resulting in material residue at the discharge port during subsequent uses. Therefore, to address these shortcomings, this invention proposes a granulation device for the production of compound microbial fertilizers. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-Figure 4 As shown, a granulation device for producing compound microbial fertilizer is disclosed, comprising a base 1, a mixing tank 2 fixedly connected to the upper surface of the base 1 by a vertical rod, a first feed inlet 21 opened on one side of the top wall of the mixing tank 2, a mixing assembly 3 installed in the middle of the mixing tank 2, and a discharge pipe installed at the bottom of the mixing tank 2. A feeding pipe 5 is fixedly connected to the bottom end of the discharge pipe, and one end of the feeding pipe 5 is open. An auger 6 is rotatably connected inside the feeding pipe 5. A second motor 7 is fixedly fixed at the end of the feeding pipe 5 away from the open end, and the output end of the second motor 7 is fixedly connected to the central shaft of the auger 6. A detachable cutting assembly 8 is fixedly fixed at the open end of the feeding pipe 5. A drying assembly 9 is installed on the upper surface of the base 1 and below the cutting assembly 8. A fan 10 is fixedly fixed on the upper surface of the base 1. An air guide pipe 11 is fixedly connected to the exhaust port of the fan 10. The other end of the air guide pipe 11 is connected to the drying assembly 9, and a heating pipe 12 is connected to the middle of the air guide pipe 11.

[0024] The stirring assembly 3 includes a first motor 31 fixed to the top wall of the stirring tank 2, a stirring shaft 32 fixed to the bottom drive end of the first motor 31, and a plurality of stirring rods 33 fixed to the surface of the stirring shaft 32.

[0025] After the microbial fertilizer raw materials are put into the mixing tank 2 through the first feed inlet 21, the first motor 31 can be started to drive the stirring rod 33 to rotate, so that the fertilizer raw materials are mixed with water.

[0026] A valve 4 is fixedly installed in the middle of the discharge pipe. By opening the valve 4, the mixed material can enter the feeding pipe 5 along the discharge pipe. At this time, the second motor 7 is started to drive the auger 6 to rotate, which can transport the material to one side of the cutting assembly 8.

[0027] The cutting assembly 8 includes a side cover 81 sleeved on the surface of the feeding tube 5. The side cover 81 has several material holes 82. A shaft 83 is rotatably connected to the middle of the side cover 81 via a bearing. Multiple cutters 84 are fixed at one end of the shaft 83 outside the side cover 81, and the multiple cutters 84 are in contact with the surface of the side cover 81. A square slot 85 is opened at one end of the shaft 83 inside the side cover 81. A connecting block 61 is fixed at one end of the auger 6 near the side cover 81, and the connecting block 61 is engaged inside the slot 85.

[0028] As the material moves toward the side cover 81, it is squeezed through the material hole 82 on the side cover 81, causing the material to be extruded in a long strip shape. During this process, the auger 6 will also drive the shaft 83 and multiple cutters 84 on the outer wall of the shaft 83 to rotate synchronously, thereby using the cutters 84 to cut the long strip material into granules.

[0029] The side cover 81 is fixedly connected to the feed pipe 5 by bolts. Therefore, the side cover 81 can be removed from the surface of the feed pipe 5, making it convenient to clean the material stuck in the feed hole 82 after each use of the device.

[0030] The drying assembly 9 includes a drying box 91 fixed to the upper surface of the base 1, and a second feed inlet 95 is provided on the top wall of the drying box 91. The second feed inlet 95 is located below the cutting assembly 8. A baffle 96 is fixed on the upper surface of the drying box 91 near the second feed inlet 95. A fan hood 93 is fixed on one side of the drying box 91. The air guide pipe 11 is fixedly connected to the fan hood 93. An air outlet 94 is provided on the side of the drying box 91 away from the fan hood 93. A mesh is fixed inside the air outlet 94. An electric heating wire is provided inside the heating tube 12. A discharge port is provided at the bottom of the drying box 91.

[0031] After the material enters the drying chamber 91 through the second feed inlet 95, it will fall inside the drying chamber 91. During this process, the electric heating wire will heat the air in the air duct 11, and then blow the heated air into the drying chamber 91, thereby using high temperature air to dry the fertilizer granules.

[0032] Multiple inclined guide plates 92 are fixed inside the drying chamber 91, and the guide plates 92 are arranged in an alternating manner. The multiple guide plates 92 can guide the falling fertilizer granules, thereby increasing the falling time of the fertilizer granules inside the drying chamber 91 and thus improving the drying effect.

[0033] Working principle: The raw materials for producing fertilizer granules are fed into the mixing tank 2 through the first feed port 21. After adding an appropriate amount of water, the first motor 31 is started to drive the stirring rod 33 to mix the materials. After mixing, the valve 4 is opened so that the materials enter the feeding pipe 5 along the discharge pipe. Then, the second motor 7 is started to drive the auger 6 to rotate. The auger 6 is used to squeeze the fertilizer raw materials towards the material hole 82. After passing through the material hole 82, the fertilizer raw materials are cut into granules by the rotating cutter 84. The granulated fertilizer enters the drying chamber 91 through the second feed port 95. At this time, the blower 10 and the electric heating wire inside the heating tube 12 are started, so that the blower 10 blows hot air to dry the fertilizer granules entering the drying chamber 91. The dried fertilizer granules are discharged from the discharge port on one side of the drying chamber 91.
