Detailed Description
The following are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention.
In the present embodiment, the words such as "left", "right", "inner", "outer", etc. describing the directional relationship are only for convenience of description of the embodiment, and are not to be considered as limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
Fig. 1 shows an embodiment of the present invention. This embodiment provides a kitchen garbage screw extrusion hydroextractor. The kitchen waste spiral extrusion dehydrator can be used for dehydration treatment in the fields of kitchen waste treatment, sludge treatment and the like. The utility model can be used in the fields of fruit and vegetable juice squeezing, medicine, fermentation, etc.
This kitchen garbage screw extrusion hydroextractor includes barrel 16, and the both ends of barrel 16 are feed end 100 and discharge end 200 respectively, and the roof of feed end 100 is equipped with the feed inlet, and feed bin 15 passes through modes such as bolt or welding and feed inlet fixed connection. The lower part of the cylinder 16 is concave downwards to form a funnel-shaped liquid collecting bin 9. The liquid outlet 17 arranged at the lower part of the liquid collecting bin 9 can be connected with a sewage treatment system through a pipeline, and a container for collecting waste liquid can be arranged at the outlet. In order to be convenient to use, a section of water pipe can be installed at the liquid outlet 17 in a welding mode, a screwing mode and the like.
The sidewall of the feed end 100 is provided with a first through hole, and the sidewall of the discharge end 200 is provided with a second through hole, wherein the diameter of the second through hole is larger than that of the first through hole. The outer side of the first through hole is fixedly connected with a bearing 6 through a bolt. The second through hole is used as a discharge hole of the kitchen waste spiral extrusion dehydrator. The reducing screw 7 axially arranged along the cylinder 16 penetrates the whole cylinder 16. The reducing screw 7 comprises a central shaft 71, wherein the central shaft 71 comprises a first equal-diameter section which is connected with the output end of the speed reducer 3 through a coupling 5 and a transmission bearing 6, a second equal-diameter section which passes through a second through hole of the cylinder 16 and is connected with a bearing in the bearing seat 14, and a reducing section which is positioned on the first equal-diameter section and the second equal-diameter section. The variable diameter section of the central shaft 71 is located in the cylinder 16, the diameter of the variable diameter section is gradually increased from the first equal diameter section to the second equal diameter section, and a spiral conveying blade 72 is welded. The length of the variable diameter section is less than or equal to the length of the cylinder 16. The inside of the cylinder 16 is provided with a filter screen 8. As shown in fig. 1, the screen 8 is shaped to match the shape of the cylinder 16 and is sized slightly smaller than the cylinder 16 so that a gap is left between the screen 8 and the cylinder 16. The filter screen 8 is connected with the wall of the cylinder 16 through bolts.
The input end of the speed reducer 3 is connected with the output end of the motor 1.
A sealing device is arranged at the second through hole of the cylinder 16. As shown in fig. 1, the closure includes a conical disk 10 and a spring 12. The diameter of the bottom end of the conical disc 10 is larger than that of the second through hole. The conical disc 10 is sleeved outside the second equal-diameter section of the central shaft 71 of the reducing screw 7. The conical disc 10 is in clearance fit with the second through hole of the cylinder 16. The spring 12 is sleeved on the central shaft 71 of the reducing screw 7 between the conical disc 10 and the bearing seat 14. One end of the spring 12, which is in contact with the conical disc 10, is clamped in a groove at the bottom of the conical disc 10, and the other end of the spring is clamped in a groove of the bearing seat 14. Just the spring 12 is at the free length when the device is not operating. As shown in fig. 1, due to the tapered section of the central shaft 71 and the presence of the spring 12, the position of the conical disk 10 is relatively fixed and the conical disk is just in clearance fit with the second through hole of the cylinder 16.
When the kitchen waste dewatering machine is used, firstly, kitchen waste is poured into the bin 15, then the driving motor 1 is started, the driving motor 1 drives the reducing screw 7 to rotate, the kitchen waste enters the barrel 16 from the bin 15 through the feeding hole, and under the pushing action of the spiral conveying blades 72, the kitchen waste spirally extrudes the feeding end 100 of the dewatering machine to move to the discharging end 200. Because the diameter of the reducing section of the reducing spiral 7 is gradually increased, the extrusion force of the reducing spiral 7 and the filter screen 8, which is applied to the kitchen waste in the moving process, is gradually increased, and the moisture in the kitchen waste is extruded. When the kitchen waste reaches the second through hole of the cylinder 16, the kitchen waste is blocked due to the existence of the conical disc 10, the reducing screw 7 continuously pushes the subsequent kitchen waste to the second through hole, so that the extrusion force between the reducing screw 7, the filter screen 8 and the conical disc 10 at the second through hole is further increased, and the moisture is further extruded. When the thrust provided by the reducing screw 7 to the kitchen waste is greater than the elastic force of the spring 12, the spring 12 is compressed, the conical disc 10 moves towards the bearing seat 14, the gap between the second through hole and the conical disc 10 is increased, and the dehydrated kitchen waste flows out from the gap.
The whole kitchen waste screw extrusion dehydrator is fixed on the support 4 through bolts. A receiving hopper 11 may be further provided below the second through hole of the cylinder 16.
In order to adjust the extrusion force according to the difference of the dewatering water content of the kitchen waste, an external thread is arranged at the position, close to the bearing seat 14, of the second equal-diameter section of the central shaft 71, a handle 13 is sleeved at the position of the external thread, an internal thread matched with the external thread of the central shaft 71 is arranged in the handle 13, and a groove clamped with the spring 12 is arranged on at least one side, facing the conical disc 10, of the handle 13. Spring 12 is fitted over central shaft 71 between handle 13 and conical disk 10. When the water content in the kitchen waste is high, the handle 13 is rotated before the spiral extrusion dehydrator of the kitchen waste is started, and the spring is compressed. At the moment, a larger force is needed to push the conical disc to move, so that the kitchen waste can be subjected to a larger extrusion force near the second through hole, and the kitchen waste is dehydrated more thoroughly.
The conical disc 10 selected in this embodiment is used to prevent the kitchen waste from being discharged without being dehydrated sufficiently, and therefore, the sealing member that can perform the above-described function may be used, and is not limited to the conical disc shape, and may have other shapes such as a cylindrical shape. The conical disc 10 is selected in the embodiment to make the discharging more smooth. The motor 1 and the reducer 3 may be replaced with other driving devices such as a hydraulic motor and an internal combustion engine. The filter screen may be provided only at the bottom of the cylinder 16. The pitch between the spiral conveying blades 72 in this embodiment can be gradually reduced along with the increase of the diameter of the variable diameter section, so that the kitchen waste is more sufficiently squeezed and dehydrated in the process of being pushed by the spiral conveying blades 72.
