Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to a proportioning and mixing device for compound fertilizers with high magnesium content. Background Art

[0002] Compound fertilizers refer to fertilizers containing specified amounts of two or more of the three elements: nitrogen, phosphorus, and potassium. This type of fertilizer can be made through chemical synthesis and mixing, including binary and ternary types. Compound fertilizers can save packaging and transportation costs, reduce the number of fertilization times, and can also be designed with nutrient formulas based on local soil nutrient supply conditions and the fertilizer requirements of target crops.

[0003] In the production process of compound fertilizers, a mixing device is required to mix various additives with raw materials in a certain proportion. However, some compound fertilizer raw materials with high magnesium content are easy to absorb moisture and agglomerate during storage due to their high solubility and strong hygroscopicity. This also leads to uneven mixing when mixing them with other additives later, reducing the quality of the finished product. Utility Model Content

[0004] The purpose of the utility model is to provide a proportioning and mixing device for compound fertilizers with high magnesium content, so as to solve the technical problem that a large amount of lumps exist in the raw materials of most existing proportioning and mixing devices for compound fertilizers with high magnesium content when in use.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, a proportioning and mixing device for high-magnesium-content compound fertilizer includes a mixing tank 1, an internal rotating stirring paddle 20 is provided for the mixing tank 1, a feeding end 21 is provided at the top of the mixing tank 1, a discharging end 22 is provided at the bottom of the mixing tank 1, and a base 23 is provided on the periphery of the mixing tank 1. When the device is in use, an additive formulated with a high-magnesium-content compound fertilizer raw material is added into the mixing tank 1 through the feeding end 21, and then the stirring paddle 20 is used to mix and stir. After the stirring is completed, the material is discharged through the discharging end 22, and a movable sealing door for sealing the discharging end 22 is provided at the discharging end 22. A motor for driving the stirring paddle 20 to rotate is provided at one end of the mixing tank 1. The blades of the stirring paddle 20 are flat devices, which can perform secondary crushing on the lumps remaining in the raw materials during the stirring and mixing process.

[0024] A feeding pipe 2 is provided at one end of the top of the mixing tank 1, and a screen 3 is provided obliquely inside the feeding pipe 2. A drying box 4 and a moisture absorption box 11 are sequentially provided on the top of the mixing tank 1. A hopper 5 is provided inside the drying box 4, and a sealing plate 6 is provided on the drying box 4 to seal the bottom end of the hopper 5. A connected crushing box 7 is provided on the top of the drying box 4, and a crushing assembly for crushing is provided on the crushing box 7. The crushing assembly includes two sets of mutually meshing crushing rollers 8 rotatably arranged inside the crushing box 7, and a transmission gear 9 rotatably arranged on one side of the crushing box 7 and matching the crushing rollers 8. A receiving pipe 10 connected to the feeding pipe 2 is provided on the top of the crushing box 7;

[0025] The moisture absorption box 11 is connected to the drying box 4 through the exhaust pipe 12, and the interior of the moisture absorption box 11 is provided with a moisture absorption component, which includes a filter plate 13 horizontally mounted inside the moisture absorption box 11, and a filter cloth is laid on the top of the filter plate 13. The interior of the moisture absorption box 11 is filled with moisture absorption material 14, and the moisture absorption material 14 is located above the filter plate 13. A hot air box 15 is provided on one side of the feeding pipe 2, and the hot air box 15 is connected to the drying box 4 through the air supply pipe 16. The interior of the drying box 4 is respectively provided with a dust cover 17 matching the exhaust pipe 12 and the air supply pipe 16. The interior of the hot air box 15 is provided with an exhaust fan 18 and an electric heating wire 19. When the device is feeding high-magnesium-content compound fertilizer raw materials, the raw materials enter the mixing tank 1 through the feeding pipe 2. During the feeding process, the screen 3 arranged in the feeding pipe 2 can screen the raw materials according to the particle size, so that the agglomerated raw materials roll along the screen 3 to the receiving pipe 10 and enter the crushing box 7 through the receiving pipe 10. The crushing box 7 is provided with a motor for driving the crushing roller 8 to rotate. After the crushing roller 8 crushes the agglomerated raw materials, the raw materials fall into the drying box 4. At this time, the exhaust fan 18 and the heating wire 19 are started. The exhaust fan 18 and the heating wire 19 generate a hot air flow to blow into the drying box 4, which can dry the relatively moist raw materials in the drying box 4. It should be noted that the hot air flow should be relatively smooth to prevent the raw materials in the drying box 4 from flying around. By pulling the sealing plate 6, the dried raw materials can be put back into the mixing tank 1. When drying the moist raw materials, the hot air in the drying box 4 can enter the mixing tank 1 along the exhaust pipe 12, thereby maintaining the working environment in the mixing tank 1 at a certain temperature, preventing the raw materials from getting damp during the stirring process. The hygroscopic material 14 can absorb moisture from the hot air discharged from the exhaust pipe 12, thereby further improving the dryness of the raw materials in the mixing tank 1.

[0026] In this embodiment, specifically, the mixing tank 1 is provided with slots connected to the drying box 4 and the moisture absorption box 11 respectively. The drying box 4 and the moisture absorption box 11 are both located on one side of the feeding pipe 2, and the top of the receiving pipe 10 is close to the lowest end of the screen 3.

[0027] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
