Description

Technical Field

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

[0002] Pretreatment for fertilizer production involves screening organic waste, including animal manure, plant residues, vegetable waste, and other organic waste. To ensure the quality of organic fertilizer, pretreatment equipment for fertilizer production is needed to collect and pretreat the organic waste. Pretreatment includes many steps, all of which are preparations for subsequent processing.

[0003] In the pretreatment process of fertilizer production, it is necessary to separate solids and liquids in some mixtures to avoid excessive moisture in the fertilizer raw materials, which would affect fertilizer production. Existing fertilizer production pretreatment equipment usually uses multiple screens to screen solids when separating fertilizer raw materials. However, when the solid-liquid mixture passes through the screen, some solids accumulate on the screen, which can easily cause screen blockage. This prevents the liquid on the upper part of the screen from passing through, affecting the screening of the solid-liquid mixture. Therefore, this method needs to be improved. Utility Model Content

[0056] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a pretreatment device for fertilizer production.

[0057] A pretreatment device for fertilizer production includes a support frame 1 and a support frame 2, with the support frame 2 fixedly connected to the support frame 1; it also includes: two guide blocks 3 symmetrically arranged within the support frame 1 and fixedly connected to the support frame 1; a discharge pipe 4 located at the bottom of the support frame 1 and fixedly connected to the support frame 1; a screen 5 for solid-liquid separation of fertilizer raw materials; an extrusion mechanism located on the support frame 2 for extruding the solid-liquid mixture within the screen 5 to accelerate the separation of the solid-liquid mixture; an extrusion plate 6 for extruding the solid-liquid mixture; and a lifting mechanism located on the support frame 1 for lifting the screen 5.

[0059] When in operation, the extrusion motor 8 is started, which drives the extrusion shaft 9, which is fixedly connected to the output end of the extrusion motor 8, to rotate.

[0060] Reference Figure 2 and Figure 5 In a preferred embodiment, the sliding component includes: a sliding groove 10, which is formed on the support frame 2; two sliding blocks 11, which are symmetrically arranged in the sliding groove 10, slidably connected to the sliding groove 10, and threadedly connected to the extrusion shaft 9; and a rotating component, which is disposed on the sliding blocks 11.

[0061] During operation, the sliding block 11, which is threadedly connected to the extrusion shaft 9, rotates, causing the sliding block 11 to slide within the sliding groove 10, so that the sliding blocks 11 move closer to each other.

[0062] Reference Figure 5In a preferred embodiment, the rotating component includes: a first rotating shaft 12, which is disposed on the sliding block 11 and fixedly connected to the sliding block 11; a rotating plate 13, which is rotatably connected to the first rotating shaft 12; a second rotating shaft 14, which is rotatably connected to the rotating plate 13; and a rotating frame 15, which is fixedly connected to the second rotating shaft 14 and fixedly connected to the pressing plate 6.

[0063] During operation, the rotating plate 13, which is rotatably connected to the first rotating shaft 12, rotates, causing the rotating frame 15, which is fixedly connected to the second rotating shaft 14, to move the extrusion plate 6 away from the support frame 2, so that the extrusion plate 6 slides into the screen 5.

[0064] Reference Figure 4 In a preferred embodiment, the lifting mechanism includes: a lifting frame 16, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a lifting motor 17, which is fixedly connected to the lifting frame 16; a lifting shaft 18, which is fixedly connected to the output end of the lifting motor 17 and rotatably connected to the support frame 1; a lifting gear 19, which is fixedly connected to the lifting shaft 18; and a moving component disposed on the support frame 1.

[0065] When in operation, the lifting motor 17 is started, which drives the lifting shaft 18, which is fixedly connected to the output end of the lifting motor 17, to rotate, causing the lifting gear 19, which is fixedly connected to the lifting shaft 18, to rotate.

[0066] Reference Figure 3 and Figure 4 In a preferred embodiment, the moving component includes: a moving groove 20, which is formed on the support frame 1; a moving tooth block 21, which is disposed in the moving groove 20, slidably connected to the moving groove 20, and meshing with the lifting gear 19; and two rotating components, which are symmetrically arranged on the screen 5.

[0067] During operation, it drives the moving tooth block 21, which meshes with the lifting gear 19, to slide within the moving groove 20.

[0068] Reference Figure 4 In a preferred embodiment, the rotating component includes: a rotating shaft 22, which is disposed on the screen 5 and fixedly connected to the screen 5; a rotating block 23, which is rotatably connected to the rotating shaft 22 and fixedly connected to the moving toothed block 21; a screen plate 24 is disposed on the screen 5, and the screen plate 24 is detachably fixedly connected to the screen 5 and is used to transport and unload the solids screened inside the screen 5; a support block 25 is disposed on the support frame 1, the support block 25 is slidably connected to the support frame 1 and fixedly connected to the rotating block 23.

[0069] During operation, the rotating block 23, which is fixedly connected to the moving toothed block 21, moves, causing the screen 5, which is fixedly connected to the rotating shaft 22, to move outward of the support frame 1, so that the support block 25 slides inside the support frame 1. When the screen 5 rises to a certain height, the screen 5 is pulled, causing the rotating shaft 22, which is fixedly connected to the screen 5, to rotate inside the rotating block 23, causing the screen 5 to tilt.

[0070] Working principle: In use, the solid-liquid mixture is first placed in the screen 5, and then the extrusion motor 8 is started, which drives the extrusion shaft 9, which is fixedly connected to the output end of the extrusion motor 8, to rotate. This causes the sliding block 11, which is threadedly connected to the extrusion shaft 9, to rotate and slide in the sliding groove 10, so that the sliding blocks 11 move closer to each other. This causes the rotating plate 13, which is rotatably connected to the first rotating shaft 12, to rotate. This causes the rotating frame 15, which is fixedly connected to the second rotating shaft 14, to move the extrusion plate 6 away from the support frame 2, so that the extrusion plate 6 slides into the screen 5, thereby extruding the solid-liquid mixture in the screen 5, making the solid-liquid mixture separate more quickly and thoroughly.

[0071] Next, after the solid-liquid mixture is screened, the lifting motor 17 is started, which drives the lifting shaft 18, which is fixedly connected to the output end of the lifting motor 17, to rotate. This causes the lifting gear 19, which is fixedly connected to the lifting shaft 18, to rotate, thereby causing the moving tooth block 21, which meshes with the lifting gear 19, to slide in the moving groove 20. This causes the rotating block 23, which is fixedly connected to the moving tooth block 21, to move, which causes the screen 5, which is fixedly connected to the rotating shaft 22, to move to the outside of the support frame 1. This causes the support block 25 to slide in the support frame 1, thereby lifting and lowering the screen 5. When the screen 5 rises to a certain height, the screen 5 is pulled, causing the rotating shaft 22, which is fixedly connected to the screen 5, to rotate in the rotating block 23. This causes the screen 5 to tilt, thereby enabling the rapid unloading of the solid material inside the screen 5.

[0072] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
