Description

Technical Field

[0001] This invention relates to the dehydration treatment of waste, and more particularly to a solid-liquid separation system for kitchen waste. Background Technology

[0002] Currently, kitchen waste is typically buffered by filters in the pipes and then removed for centralized processing once a certain amount has accumulated. Due to its high water content, this type of food waste usually undergoes solid-liquid separation first. This is done by using a squeezing device to remove the water, and the wastewater is then purified before being discharged. However, the current equipment has a drawback: the squeezing chamber has a mesh frame structure. During squeezing, the waste is crushed, and smaller pieces flow out with the extruded water through the mesh, leaving some waste in the separated liquid. This adds to the burden on subsequent purification processes. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0036] An embodiment of the present invention provides a solid-liquid separation system for kitchen waste. The system consists of at least a loading chamber and a squeezing section. The loading chamber is used to load kitchen waste to be treated and is capable of rotational movement. The squeezing section is used to squeeze the space inside the loading chamber. At least a portion of the cavity wall located on the periphery of its own rotation axis is composed of a water-permeable section made of a water-permeable material, which is capable of liquid permeation.

[0037] The system combination in this invention centrifuges the waste through rotation during operation, and the squeezing section further promotes the separation of liquid from the waste. The liquid eventually seeps out through the permeable section, and the waste is compressed after dehydration and stored in the loading chamber. Compared with the working method of existing equipment, this invention achieves faster dehydration and higher efficiency through centrifugation and squeezing. Moreover, the permeable section prevents waste from scattering into the separated liquid during processing, resulting in a lower solid content in the separated liquid and reducing the burden on subsequent purification processes.

[0038] The above is a basic description of the working process of the present invention. The following will select a preferred embodiment to describe the structure of the present invention in detail:

[0039] like Figure 1-6As shown, the present invention includes a base 1, which is a shell-shaped structure and is used to install mechanical structures inside. Specifically, a fixed support 2 is fixedly installed inside the base 1. The present invention also includes a storage frame 4 with a columnar structure. The interior of the storage frame 4 is the loading cavity for loading kitchen waste to be processed. A rotating support 3 is constructed on the periphery of the storage frame 4. It is annular and rotates with the fixed support 2, thereby realizing the rotation of the storage frame 4 within the base 1. A gear ring 5 is constructed on the storage frame 4. A drive motor 6 is fixedly installed on the base 1. Its output end is driven by a gear and the gear ring 5. When the drive motor 6 works, it drives the rotation of the storage frame 4.

[0040] Regarding the storage frame 4, a receiving area 7 is constructed on its peripheral wall, and a drainage hole 8 is constructed through the receiving area 7. The permeable part 9 can be made of a porous sponge block and installed in the receiving area 7. A protective part 10 is also provided in the receiving area 7. The protective part 10 is a metal protective cover structure used to protect the permeable part 9. A circular opening is provided on the protective part 10 to ensure that the permeable part 9 is connected to the loading cavity area. The bottom of the storage frame 4 has a discharge port 11, and a cover 12 that is elastically connected to the storage frame 4 to cover the discharge port 11 is provided. The cover 12 is in the shape of a plate.

[0041] The extrusion section in this invention consists of an outer cover and an inner cover, which slide together along the axial direction of the storage frame 4. It is used to feed material into the loading cavity during relative movement. Specifically, the outer cover uses an outer ring plate 13, the circumference of which is adapted to the inner circumference of the storage frame 4, and an inlet 15 is formed on its inner side. The inner cover uses an inner circular plate 14, which, when slid upwards to its final position, abuts against the inlet 15, thus sealing the inlet 15. This state is suitable for the working state of the loading cavity. Conversely, when the inner circular plate 14 moves downwards to its final position, it keeps the inlet 15 open for feeding. The top of the outer ring plate 13 also has an upwardly extending funnel-shaped structure surrounding the inlet 15. A pipe interface 16 is provided on the base 1, extending downwards towards the funnel-shaped interior. Specifically, as shown... Figure 2 As shown; an alignment block 17 is also slidably arranged on the outer ring plate 13 along its own radius direction. One end of the alignment block 17 extends into the receiving area 7 and abuts against the protective part 10. The arrangement of the alignment block 17 ensures that the garbage in the loading chamber will not be thrown out from the receiving area 7 during centrifugation.

[0042] The base 1 is also provided with a pressure-applying part for applying pressure to the outer ring plate 13, such as... Figure 1-3As shown in Figure 8, the pressure application part is a hydraulic cylinder 18, which is fixedly mounted on the base 1. A rotating block 20 is rotatably mounted at the end of the piston rod 19 of the hydraulic cylinder 18. The rotating block 20 is connected to the axis of the outer ring plate 13. A return spring 21 is also provided inside the hydraulic cylinder 18 to keep the piston rod 19 in the state of retracting into the hydraulic cylinder 18 in the normal state, so that the outer ring plate 13 is positioned near the upper edge of the storage frame 4 to keep the loading cavity space at its maximum for feeding. Specifically, a column block 22 is constructed at the axis of the outer ring plate 13. The rotating block 20 is connected to the column block 22, thereby forming a fixed connection with the outer ring plate 13. At the same time, the column block 22 is also responsible for the sliding connection of the inner circular plate 14. In the normal state, the inner circular plate 14 is at the bottom of the column block 22 due to gravity, so that the feed port 15 remains open.

[0043] like Figure 3-7 As shown, the circumference of the rotating support part 3 is concave, and it forms an oil cavity 23 in conjunction with the fixed support part 2. High-density oil is provided in the cavity. An oil pipe is provided on the fixed support part 2 to the oil cavity 23, and the other end of the oil pipe is connected to the oil cylinder 18.

[0044] During installation, the outer end of the pipe interface 16 is connected to the kitchen's drain pipe. At this time, the invention acts as a filter on the drain pipe, allowing wastewater to continuously flow from the inlet 15 into the loading chamber and eventually seep out through the permeable part 9. The waste in the wastewater remains inside the loading chamber. Figure 2As shown, the base 1 also has an annular baffle 24, with a liquid storage tank 25 around the baffle 24. The liquid seeping from the permeable part 9 eventually falls into the liquid storage tank 25 and flows out to the outside of the equipment through the pipe head 26 set next to the liquid storage tank 25. The base 1 also has a notch 27, which is located inside the baffle 24, just like the discharge port 11. When the garbage in the loading chamber is full, the drive motor 6 is started, and the storage frame 4 rotates at high speed, thereby centrifugally dewatering the garbage inside. The separated sewage continues to seep out from the permeable part 9. At the same time, the oil chamber 23 rotates synchronously, and the oil is continuously squeezed into the oil cylinder 18 through the oil pipe due to centrifugal force. This causes the piston rod 19 of the oil cylinder 18 to move downward against the elastic force, thereby driving the outer ring plate 13 to move downward. At the same time, the inner circular plate 14 moves downward synchronously and presses against the garbage. As the outer ring plate 13 continues to move downward, the inner circular plate 14 abuts against the feed inlet 15 to keep the feed inlet 15 closed. At this time, the outer ring plate 13 and the inner circular plate 14 together press down on the garbage, thereby promoting the dehydration of the garbage. When the garbage is compressed to the appropriate position, its volume can no longer shrink. As the entire pressing part continues to move downward, the garbage pushes open the shielding part 12, that is, the discharge port 11 is opened. At this time, the garbage is thrown into the inner side of the partition plate 24 and finally falls out of the equipment through the opening 27. Due to the design of the column block 22 on the outer ring plate 13, when the outer ring plate 13 moves to the appropriate position, the column block 22 will eventually press against the shielding part 12, so that when the garbage in the loading cavity is thrown away, the column block 22 can still maintain the open state of the shielding part 12 to ensure that the garbage is fully thrown away.

[0045] Furthermore, regarding how to detect the accumulation of waste within the loading cavity, such as... Figure 3 As shown, a detection element 28 is also provided on the base 1. The detection element 28 can be an infrared sensor, a laser probe or a radar probe, etc., to detect whether the garbage has accumulated to the feed inlet 15. The detection element 28 can also establish a signal linkage relationship with the drive motor 6. Specifically, when the garbage is detected to have overflowed to the feed inlet 15, the drive motor 6 enters the working state.

[0046] Furthermore, regarding the elastic connection of the shielding part 12, refer to... Figure 3 and Figure 9 As shown, it adopts a structure of multiple telescopic sleeves 29. Springs are installed inside the telescopic sleeves 29 to keep the telescopic sleeves 29 elastically telescopic. The two ends of the telescopic sleeves 29 are fixedly connected to the cover part 12 and the outer wall of the storage frame 4, respectively.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
