DETAILED DESCRIPTION
[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1:
[0022] See also Figure 1-Figure 4 As shown, a granulating mechanism for producing potassium sulfate includes a granulator body 1, a feed trough 2 and a discharge trough 3. The feed trough 2 is arranged at the top of the granulator body 1, and the discharge trough 3 is welded to one side of the lower end of the granulator body 1. Potassium sulfate compound fertilizer is a common fertilizer. When producing potassium sulfate fertilizer, the raw materials need to be put into the granulator for processing. Some agglomerated or granulated potassium sulfate fertilizers need to be crushed so that the particles or blocks of potassium sulfate fertilizers become powder. A screening structure 4 is installed inside the feed trough 2. The screening structure 4 includes a screening plate 1 41 and a screening plate 2 42. The two sides of the screening plate 1 41 are fixed to the inner wall of the feed trough 2. The screening plate 1 41 and the screening plate 2 42 are fixed to the inner wall of the feed trough 2. There is a gap between the two surfaces, so that the potassium sulfate fertilizer poured into the feed trough 2 can be concentrated on the surface of the screen plate 41. Connecting bolts 43 are connected between the two sides of the screen plate 41 and the two sides of the connecting bolts 43. The surface of the screen plate 41 and the surface of the screen plate 2 are respectively provided with a plurality of reserved grooves 45 and a plurality of reserved grooves 44. The groove width of the reserved groove 2 45 is greater than the groove width of the reserved groove 1 44. The powdered potassium sulfate fertilizer falls from the reserved groove 2 45 and the reserved groove 1 44. The granular or block potassium sulfate can be retained at the screen plate 41 and the screen plate 2 42. Only when the granular or block potassium sulfate fertilizer is turned into powder can it enter the internal processing of the granulator body 1.
[0023] In this embodiment, a row of baffle plates 46 are welded on the surface of the screening plate 41, and the plane where the baffle plates 46 are located is staggered with the plane where the screening plate 41 is located. The baffle plates 46 are used to retain potassium sulfate at different positions to avoid the accumulation of too much potassium sulfate in one place, which is not conducive to the crushing of granular or block potassium sulfate.
[0024] In this embodiment, the edge of the screen plate 1 41 is fixed to the inner wall of the feed trough 2 by bolts, and there is a gap between the edge of the screen plate 2 42 and the inner wall of the feed trough 2, so that some relatively large particles can be crushed or squeezed.
[0025] In this embodiment, a rolling structure 5 is provided on both sides of the screen plate 1 41 and the screen plate 2 42, and the rolling structure 5 includes a telescopic spring 1 51, and the telescopic spring 1 51 is sleeved on each connecting bolt 43, and the telescopic spring 1 51 is located between the screen plate 1 41 and the screen plate 2 42, and a gasket 52 is provided at the intersection of the screen plate 1 41 and each connecting bolt 43, so that the screen plate 2 42 can be swung in different directions when the equipment moves, and a floating hole 53 is provided at the intersection of the screen plate 1 41 and the connecting bolt 43, and the connecting bolt 43 swings inside the floating hole 53, and the diameter of the floating hole 53 is larger than the diameter of the connecting bolt 43, and the connecting bolt 43 is movably connected to the inside of the floating hole 53, and the relatively swinging screen plate 1 41 and screen plate 2 42 can extrude and grind the potassium sulfate fertilizer trapped between the two plates, so that the potassium sulfate fertilizer can be discharged from the screen plate 2 42.
[0026] In this embodiment, connecting plates 54 are welded on both sides of the second screening plate 42, and a telescopic spring 2 55 is connected between the connecting plate 54 and the inner wall of the feed trough 2, and the telescopic spring 2 55 is in contact with the inner wall of the feed trough 2. The telescopic spring 2 55 can not only squeeze the potassium sulfate fertilizer in the gap, but also reset the screen plate 42 after the equipment stops running.
[0027] When the utility model is in use, potassium sulfate compound fertilizer is a common fertilizer. When producing potassium sulfate fertilizer, the raw materials need to be placed in a granulator for processing, and some agglomerated or granulated potassium sulfate fertilizers need to be crushed so that the granules or blocks of potassium sulfate fertilizer are turned into powder. There is a gap between the screening plate 1 41 and the screening plate 2 42, so that the potassium sulfate fertilizer poured into the feed trough 2 can be concentrated on the surface of the screening plate 1 41, and the potassium sulfate is retained at different positions by the baffle plate 46 to avoid too much potassium sulfate gathering in one place, which is not conducive to crushing granular or block potassium sulfate. There is a gap between the edge of the screening plate 2 42 and the inner wall of the feed trough 2, so that some relatively large particles can be crushed or squeezed, and the powdered potassium sulfate fertilizer falls from the reserved slot 2 45 and the reserved slot 1 44. For granular or block potassium sulfate, The potassium sulfate fertilizer trapped in the screening plate 1 41 and the screening plate 2 42 can only be converted into powder by the granular or block potassium sulfate fertilizer into powder before it can enter the internal processing of the granulator body 1. When the equipment moves, the screening plate 2 42 can be swung in different directions. The intersection of the screening plate 1 41 and the connecting bolt 43 is provided with a floating hole 53, and the connecting bolt 43 swings inside the floating hole 53. The diameter of the floating hole 53 is larger than the diameter of the connecting bolt 43. The connecting bolt 43 is movably connected to the inside of the floating hole 53. The relatively swinging screening plate 1 41 and the screening plate 2 42 can squeeze and grind the potassium sulfate fertilizer trapped between the two plates, so that the potassium sulfate fertilizer can be discharged from the screening plate 2 42. The telescopic spring 2 55 can not only squeeze the potassium sulfate fertilizer in the gap, but also reset the screening plate 2 42 by the telescopic spring 2 55 after the equipment stops running.
[0028] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
