In a specific embodiment, the extrusion device provided by the embodiment of the invention extrudes and dewaters the organic waste materials under the extrusion force formed by the spiral blades with the spiral diameters changed and the baffle plate. The organic waste extrusion device with automatic control provided by the embodiment of the invention has a variable-diameter spiral structure, and the reduction or increase of the spiral diameter realizes the reduction or increase of extrusion force. The reducing slide block 6 in the automatic control organic waste extrusion device provided by the embodiment is formed by uniformly dividing a circular shaft with a conical inner hole into a plurality of sections along the axial direction, and the conical slide block 7 moves on a sliding groove on the inner surface of the reducing slide block 6, so that the reducing slide block 6 is unfolded outwards or retracted inwards along the radial direction. The reducing slider 6 expands radially outwards as the conical slider 7 moves inwards on the sliding groove of the inner surface of the reducing slider 6. The reducing slider 6 is retracted radially inwards as the conical slider 7 moves outwards on the sliding groove of the inner surface of the reducing slider 6. The spiral blades 4 are equally divided axially like the reducing slide blocks 5, but have a certain mutual overlapping distance, and each group of blades is respectively fixed on the corresponding reducing slide blocks 6. When the reducing slider 6 is radially expanded outwards or retracted inwards, the helical blades 4 are also outwards or inwards together, so that the size of the helical diameter is changed, and the distance of the overlapping parts of the blades ensures that no intermittent gaps exist between each group of blades. After the reducing slide blocks 6 are unfolded, gaps are reserved among the slide blocks, and in order to prevent materials from entering the reducing slide blocks, the reducing slide blocks 6 need to be sealed and protected by the variable-diameter shaft cylinder 5. The diameter-variable shaft cylinder 5 is also formed by a plurality of circular arc segments uniformly distributed in the circumferential direction, each group of circular arc segments is fixed on the corresponding spiral blade 4 and moves along with the spiral blade 4 in the radial direction, and the plane parts of the circular arc segments are mutually overlapped to ensure that no material leakage occurs after radial expansion. The reducing slide chuck 2 transmits torque of the extruder rotation driving device 1 to the reducing slide 6 to drive the reducing slide 6 to rotate. The conical body slide block driving device 9 drives the conical body slide block 7 to move, the spiral diameter is increased or decreased, and the extrusion force is adjusted. Meanwhile, the automatic control organic waste extrusion device provided by the embodiment prevents materials from being blocked at the spiral part by changing the space between the outer cylinder 3 and the variable diameter shaft cylinder 5 of the extruder.
It is noted that each component/step described in the present application may be split into more components/steps, or two or more components/steps or part of the operations of the components/steps may be combined into new components/steps, as needed for implementation, to achieve the object of the present invention.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
