In the present embodiment, the dewatering mechanism 8 is provided in the dewatering cylinder 5 to press and convey the water-containing fiber crushed material entering the dewatering cylinder 5 from the crushed material inlet 61 to the crushed material outlet 62, and the dewatering mechanism 8 may be a dewatering mechanism having a plurality of helical blades provided on a rotating shaft (as shown in fig. 1), or other dewatering mechanisms of the prior art may be used.
As shown in fig. 1, the liquid collecting tank 100 is provided below the dewatering cylinder 5, and is capable of collecting water removed from the wet fiber waste, at least the lower part or the whole of the dewatering cylinder 5 has a mesh structure, and water continuously squeezed out of the wet fiber waste by the spiral blades of the dewatering mechanism 8 flows down into the liquid collecting tank 100 along the mesh of the dewatering cylinder 5 and is collected. The sump 100 is provided with a drain for draining the residual liquid therein. As shown in fig. 1, a dry material tank 110 is disposed below the crushed material outlet 62 for collecting the dehydrated hydrous fiber crushed material, and a dry material outlet is disposed at one side of the dry material tank 110 for pouring out the dehydrated dry material (i.e., the dehydrated hydrous fiber crushed material).
Alternatively, the dehydration apparatus of the present invention may be a dehydration apparatus of the prior art.
In conclusion, compared with the prior art, the pretreatment equipment for the kitchen waste has the following advantages:
1. the device comprises a crushing and conveying device, a dehydrating device, a material outlet and a dehydrating device, wherein the crushing and conveying device is used for crushing the water-containing fiber material;
2. the rotary cutter component of the crushing and conveying device is provided with the plurality of crushing cutters which are spirally and alternately arranged on the rotating shaft, when the crushing cutters are driven by the rotating shaft to rotate, the crushing cutters not only crush the water-containing fiber materials but also push the water-containing fiber materials to move forwards along the axial direction, so that the water-containing fiber materials can be crushed for multiple times by the plurality of groups of crushing cutters which are spirally arranged, the crushing working efficiency is greatly improved, the fiber materials entering the dewatering device are guaranteed to be very finely crushed, especially, the material conveying can be realized without additionally arranging a conveying mechanism, the equipment structure is compact, and the equipment cost can be saved.
3. The equipment has low maintenance cost. Because each blade in the rotary cutter assembly can be independently replaced by a new blade when damaged, and the whole rotary cutter assembly does not need to be replaced, the loss part is convenient to replace and maintain, and the maintenance cost is greatly saved.
Although the present invention has been described in detail, the present invention is not limited thereto, and those skilled in the art can modify the principle of the present invention, and thus, various modifications made in accordance with the principle of the present invention should be understood to fall within the scope of the present invention.
