Description

Technical Field

[0001] The invention belongs to the technical field of agricultural processing, and in particular relates to a device and a method for producing medium and trace element fertilizers. Background Art

[0002] The nutrients required by plants are divided into macronutrients (nitrogen, phosphorus, potassium), secondary nutrients (calcium, magnesium, sulfur), and trace nutrients (iron, boron, manganese, zinc, etc.). Fertilizers containing both macronutrients and trace nutrients are used to supplement these nutrients.

[0003] Compared to traditional fertilizers, medium and trace element fertilizers usually require the addition of multiple raw materials to meet the needs of the addition of multiple medium and trace elements. The production process usually involves raw material processing, formula design, material mixing, drying and screening, and finished product packaging. The characteristics of medium and trace element fertilizers make the material mixing process the most important production link. In the traditional medium and trace element fertilizer production process, after the formula is determined, the raw materials are usually directly poured into the mixing equipment according to the formula ratio. This production method not only wastes raw materials, but also generates a large amount of dust, polluting the environment, easily causing health damage to operators, and may also cause serious accidents such as dust explosions.

The rotation of the top cover 11 can drive the filtering mechanism 2 to connect with different feeding mechanisms 3;

[0056] The raw materials conveyed by the feeding mechanism 3 enter the mixing tank 1 through the filtering mechanism 2 .

[0057] In this embodiment, different raw materials can be put into different feeding mechanisms 3 according to the formula during the production process. The top cover 11 drives the filtering mechanism 2 to dock with different feeding mechanisms 3. The raw materials transported by the feeding mechanism 3 enter the mixing tank 1 through the filtering mechanism 2, so that different raw materials can be put into the mixing tank 1 in sequence according to the formula. There is no need for the operator to manually dump the raw materials, which effectively reduces the difficulty of the operator's work. The fan 4 can blow air into the feeding mechanism 3, and the auxiliary raw materials enter the mixing tank 1 from the feeding mechanism 3. The fan 4 can suck air from the filtering mechanism 2, so that the dust generated by the raw materials entering the mixing tank 1 is adsorbed and collected by the filtering mechanism 2, effectively preventing the dust from escaping into the air, reducing the waste of raw materials while preventing the dust from endangering the health of the operator.

[0058] like Figure 1 - Figure 8 As shown, the feeding mechanism 3 includes a feeding air inlet 31, a feeding outlet 32 and a feeding hopper 33. The feeding hopper 33 is provided at the top of one end of the feeding mechanism 3, the feeding air inlet 31 is provided at the top of the other end of the feeding mechanism 3, and the feeding outlet 32 is provided at the bottom of the other end of the feeding mechanism 3. The top of the feeding air inlet 31 is rotatably connected to an upper cover 311, and the bottom of the feeding outlet 32 is rotatably connected to a lower cover 321;

[0059] The filter mechanism 2 includes a filter housing 21, a feed ring 22, a filter cartridge 23, and a filter plate 24. The feed ring 22 is fixedly connected to one side of the filter housing 21, the filter cartridge 23 is rotatably connected to the inside of the filter housing 21, and the filter plate 24 is rotatably connected to the bottom of the top cover 11. The top cover 11 is provided with a feed hole 112. The bottom of the feed ring 22 is connected to the feed hole 112, and the top of the feed ring 22 is connected to the feed outlet 32.

[0060] The fan 4 includes a suction pipe 41 and a blowing pipe 42. A suction joint 212 is provided on the top of the filter housing 21. The bottom of the suction pipe 41 is fixedly connected to the suction joint 212. The blowing pipe 42 is connected to the feed air inlet 31. An opening is provided on the top of the filter cartridge 23.

[0061] A first ventilation pipe 222 is provided on the side of the feeding ring 22 close to the filter housing 21, and multiple dust collection ports 221 are provided in the feeding ring 22. A second ventilation pipe 213 is provided below the filter housing 21. The first ventilation pipe 222 is fixedly connected to the second ventilation pipe 213. The first ventilation pipe 222 is communicated with the feeding ring 22, and the second ventilation pipe 213 is communicated with the filter housing 21.

[0062] In this embodiment, raw materials can enter the feeding mechanism 3 from the feed hopper 33. When the feeding mechanism 3 is not needed to transport raw materials, the upper cover 311 can block the feeding air inlet 31, and the lower cover 321 can block the feeding outlet 32, so that the raw materials are sealed in the feeding mechanism 3, and the raw materials will not leak or generate dust. Torsion springs are provided on the rotating shafts of the upper cover 311 and the lower cover 321 to keep the upper cover 311 and the lower cover 321 closed.

[0063] When the feeding mechanism 3 needs to deliver raw materials, the filtering mechanism 2 rotates to the corresponding feeding mechanism 3, the blowing pipe 42 can squeeze open the upper cover 311, and the blowing pipe 42 is connected to the feeding mechanism 3. The feeding ring 22 can squeeze open the lower cover 321. After the feeding ring 22 is aligned with the feeding outlet 32, the feeding outlet 32 can be connected to the feeding hole 112, and then the screw in the feeding mechanism 3 can deliver the raw materials to the feeding outlet 32;

[0064] The fan 4 is started and can blow air into the feeding mechanism 3 through the feeding air inlet 31. The raw materials can enter the mixing tank 1 from the feeding outlet 32 through the feeding ring 22. The feeding air inlet 31 is arranged above the feeding outlet 32. The blowing of the fan 4 can assist the raw materials to enter the mixing tank 1. The feeding ring 22 is connected with the filter housing 21, and the fan 4 can suck air from the filter housing 21, so that the dust generated by the raw materials entering the mixing tank 1 through the feeding ring 22 can be sucked by the dust collecting port 221 on the feeding ring 22, and after entering the filter housing 21, it is adsorbed by the outer wall of the filter cylinder 23.

[0065] like Figure 5 - Figure 13 As shown, a plurality of dust-removing plates 211 are fixedly provided on the inner wall of the filter housing 21, and a driven gear 231 is fixedly connected to the bottom of the filter cartridge 23;

[0066] A stirring shaft 51 is fixedly connected to the rotating shaft of the stirring motor 5, and the stirring shaft 51 passes through the top cover 11. A plurality of stirring paddles 52 are symmetrically fixedly connected to the bottom of the stirring shaft 51. A second driving gear 54 is fixedly connected to the stirring shaft 51, and the second driving gear 54 is engaged with the driven gear 231. A fan blade 53 is fixedly connected to the stirring shaft 51, and the fan blade 53 is arranged above the second driving gear 54.

[0067] In this embodiment, the stirring motor 5 can drive the stirring shaft 51 to rotate, and the rotation of the stirring shaft 51 can drive the stirring paddle 52 to mix and stir the raw materials in the mixing tank 1. The rotation of the stirring shaft 51 can also drive the second driving gear 54 to rotate. The rotation of the second driving gear 54 can drive the driven gear 231 to rotate, thereby driving the filter cartridge 23 to rotate. The rotation of the filter cartridge 23 can drive the dust-moving plate 211 to move the outer wall of the filter cartridge 23, so that the dust adsorbed on the outer wall of the filter cartridge 23 falls off.

[0068] The rotation of the stirring shaft 51 can also drive the fan blades 53 to rotate, and the rotation of the fan blades 53 can blow air toward the driven gear 231, blowing away the dust that falls from the filter housing 21 onto the driven gear 231. The driven gear 231 is also provided with a plurality of hollow holes to minimize the retention of raw material dust on the driven gear 231.

[0069] like Figure 9 - Figure 14 As shown, a through hole 114 is provided on the top cover 11 corresponding to the bottom of the filter housing 21. The bottom of the filter housing 21 is connected to the mixing tank 1 through the through hole 114. A bracket 115 is fixedly connected to the through hole 114. The shaft of the driven gear 231 passes through the bracket 115. A scraper is provided at the bottom of the bracket 115. The filter plate 24 covers the through hole 114.

[0070] One end of the filter plate 24 is fixedly connected to a driving rod 241, and the other end of the filter plate 24 is fixedly connected to a connecting plate 242. Two fixed plates 113 are fixedly connected to one side of the through hole 114. The fixed plates 113 are symmetrically arranged on both sides of the connecting plate 242. Buffer springs 2421 are fixedly connected to both sides of the connecting plate 242. The other end of the buffer spring 2421 is connected to the fixed plate 113.

The driving rod 241 and the toggling rod 12 are in the same horizontal plane, and the toggling rod 12 can toggle the driving rod 241.

[0071] In this embodiment, the dust falling into the filter housing 21 falls onto the filter plate 24 through the through hole 114, and enters the mixing tank 1 after being filtered by the filter plate 24. When the toggle rod 12 toggles the toggle rod 241, the connecting plate 242 will swing back and forth periodically between the two fixed plates 113, that is, the filter plate 24 will rotate back and forth periodically, so that the scraper can scrape and clean the filter plate 24, effectively preventing the filter plate 24 from being blocked while assisting the dust to enter the mixing tank 1.

[0072] A method for producing a medium and trace element fertilizer comprises the following steps:

[0073] Step 1: Raw material selection and processing: select raw materials according to the trace elements to be added, and crush the raw materials to 80-100 mesh to improve mixing uniformity;

[0074] Step 2: Formula design: Determine the ratio of various trace elements based on soil test data and crop needs. After determining the ratio, add different raw materials to different feeding mechanisms 3;

[0075] Step 3: Add materials. According to the formula design, select the order of adding raw materials, start the control motor 6 to drive the top cover 11 to rotate, and the top cover 11 drives the filtering mechanism 2 to connect with the feeding mechanism 3 where the raw materials need to be added. Start the fan 4, and the fan 4 blows the raw materials from the feeding mechanism 3 into the mixing tank 1 through the material ring 22. At the same time, the fan 4 provides suction for the filtering mechanism 2, so that the dust raised by the raw materials entering the mixing tank 1 enters the filtering mechanism 2 to prevent the dust from escaping into the air.

[0076] Step 4: Mixing. Start the stirring motor 5. The stirring motor 5 drives the stirring shaft 51 to stir the raw materials in the mixing tank 1. While stirring, the stirring motor 5 can drive the filter cartridge 23 in the filter mechanism 2 to rotate, so that the dust on the outside of the filter cartridge 23 falls off and falls onto the filter plate 24 below. The top cover 11 can move the filter plate 24 during the rotation process, and finally the dust on the filter plate 24 enters the mixing tank 1, ensuring that the raw materials are not wasted.

[0077] Step 5: Drying, screening and finished product packaging. After the finished product mixed in the mixing tank 1 is screened and dried, the qualified finished product is packaged to complete the production.

[0078] Working principle:

[0079] During operation, different raw materials can be put into different feeding mechanisms 3 according to the formula during the production process. The feeding mechanism 3 that does not need to transport the raw materials is not needed. The upper cover 311 can block the feeding air inlet 31, and the lower cover 321 can block the feeding outlet 32. The raw materials will be sealed in the feeding mechanism 3, and the raw materials will not leak and will not generate dust.

[0080] When a certain feeding mechanism 3 needs to deliver raw materials, the control motor 6 drives the top cover 11 to rotate. The rotation of the top cover 11 drives the filtering mechanism 2 to dock with the feeding mechanism 3. At this time, the blowing pipe 42 can squeeze open the upper cover 311, and the blowing pipe 42 is connected to the feeding mechanism 3. The feeding ring 22 can squeeze open the lower cover 321. After the feeding ring 22 is aligned with the feeding outlet 32, the feeding outlet 32 can be connected to the feeding hole 112. Then, the screw in the feeding mechanism 3 can deliver the raw materials to the feeding outlet 32.

[0081] The fan 4 is started and can blow air into the feeding mechanism 3 through the feeding air inlet 31. The raw materials can enter the mixing tank 1 from the feeding outlet 32 through the feeding ring 22. The feeding air inlet 31 is arranged above the feeding outlet 32. The blowing of the fan 4 can assist the raw materials to enter the mixing tank 1. The feeding ring 22 is connected with the filter housing 21, and the fan 4 can suck air from the filter housing 21, so that the dust generated by the raw materials entering the mixing tank 1 through the feeding ring 22 can be sucked by the dust collecting port 221 on the feeding ring 22, and after entering the filter housing 21, it is adsorbed by the outer wall of the filter cartridge 23. The filter cartridge 23 has an open top and a solid bottom. At this time, the air flow direction is from the feeding ring 22 to the filter cartridge 23, and the dust is adsorbed by the outer wall of the filter cartridge 23. The filtered air is extracted by the fan 4 and blown to the feeding mechanism 3 through the feeding air inlet 31.

[0082] The raw materials entering the mixing tank 1 are stirred and mixed by the stirring paddle 52. During this process, the rotation of the stirring shaft 51 can also drive the second driving gear 54 to rotate. The rotation of the second driving gear 54 can drive the driven gear 231 to rotate, thereby driving the filter cartridge 23 to rotate. The rotation of the filter cartridge 23 can drive the dust-moving plate 211 to move the outer wall of the filter cartridge 23, so that the dust adsorbed on the outer wall of the filter cartridge 23 falls off. The dust falling from the filter housing 21 falls onto the filter plate 24 through the through hole 114, and then enters the mixing tank 1 after being filtered by the filter plate 24.

[0083] The dust entering the mixing tank 1 falls onto the driven gear 231. The rotation of the stirring shaft 51 can also drive the fan blades 53 to rotate. The rotation of the fan blades 53 can blow air toward the driven gear 231, blowing away the dust that has fallen from the filter housing 21 onto the driven gear 231. The driven gear 231 is also provided with a plurality of holes to minimize the retention of raw material dust on the driven gear 231.

[0084] After one feeding mechanism 3 finishes conveying raw materials, the top cover 11 rotates to drive the filtering mechanism 2 to dock with the next feeding mechanism 3 that needs to convey raw materials. The upper cover 311 and the lower cover 321 of the feeding mechanism 3 that has completed conveying raw materials are reset to prevent leakage of raw materials and generation of dust. Then, the feeding mechanism 3 that needs to convey raw materials repeats the above process, and the raw materials in the feeding mechanism 3 can be conveyed into the mixing tank 1 without generating dust.

[0085] After the final raw materials are added and mixed, subsequent processes can be carried out until the finished product is packaged.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
