Description

Technical Field

[0001] This utility model relates to the field of vegetable waste processing technology, and in particular to a spiral extrusion dehydration device for vegetable waste. Background Technology

[0002] Vegetable waste refers to low-usability waste generated throughout the entire vegetable production, processing, and distribution chain, mainly including residual leaves, vines, diseased parts, and aging roots and stems. There are three main pathways for the resource utilization of vegetable waste: first, as fertilizer, through microbial rapid composting and returning to the field or earthworm composting, shortening the composting cycle and improving soil fertility; second, as feed, processing into silage to reduce costs, or extracting components to produce functional foods and pet food ingredients; and third, as energy, burning for power generation or anaerobic fermentation to produce biogas.

[0003] Because fresh vegetable scraps have a high water content and spoil quickly, resulting in high transportation and storage costs, they often need to be dehydrated during processing to reduce weight and volume and prevent rapid spoilage. Dehydration equipment is required for this process.

[0004] The sugarcane top leaf dehydration device disclosed in Chinese patent CN114789574A dehydrates sugarcane top leaves by extrusion, which not only reduces processing costs but also allows for the recycling of sugarcane juice generated during the extrusion process. However, compared with existing technologies and comparative solutions, this dehydration device still has the following problems in actual use:

[0005] When dehydrating finely fibrous vegetable scraps such as celery scraps and spinach scraps, the fine fibers in the scraps can easily get tangled in the mesh of the filter screen. If not cleaned in time, the fine fibers will become increasingly tangled, causing the filter screen to become clogged. This prevents water from the scraps from penetrating, affecting the dehydration effect. At the same time, a clogged filter screen will also be subjected to greater compressive force, affecting its lifespan. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a spiral extrusion dehydration device for vegetable waste.

[0007] The purpose of this utility model is achieved through the following technical solution: a spiral extrusion dehydration device for vegetable waste, including a support frame, an extrusion mechanism, an auxiliary cleaning component and a discharge control component are provided on the top of the support frame, the auxiliary cleaning component is slidably connected to the top of the support frame, the discharge control component is fixedly installed on the top of the support frame, and a receiving box is provided at the bottom of the support frame.

[0008] The extrusion mechanism includes a driving component, a connecting shaft at the output end of the driving component, a coupling between the connecting shaft and the output end of the driving component, an eccentric incomplete gear fixedly connected to the end of the connecting shaft near the coupling, and a spiral plate fixedly connected to the connecting shaft.

[0009] The auxiliary cleaning component includes a connecting plate, one side of which is provided with meshing teeth, a slider is fixedly connected to one side of the connecting plate, an elastic element is provided on one side of the slider, and a scraper is fixedly connected to the side of the slider away from the connecting plate.

[0011] Preferably, the discharge control component includes a drive rod, which is fixedly installed inside the connecting housing. The output end of the drive rod is fixedly connected to a discharge baffle, the position of which corresponds to the end of the connecting half-cylinder away from the drive component.

[0012] Preferably, the drive component is fixedly mounted on the top of the support frame, and the connecting shaft is rotatably connected to the support frame and the connecting shell.

[0014] Preferably, the slider is slidably connected to the connecting shell, and the elastic element is disposed between the slider and the connecting shell.

[0015] Preferably, the position of the scraper corresponds to the position of the half-cylinder of the filter screen.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This spiral extrusion dehydration device for vegetable waste not only dehydrates the waste vegetables but also cleans the fine fibers wrapped around the filter screen half-cylinder. This prevents the fine fibers from becoming increasingly entangled and causing blockage of the filter screen half-cylinder, which would prevent water from penetrating the waste vegetables and affect the dehydration effect. At the same time, it also prevents the filter screen half-cylinder from being subjected to greater extrusion pressure when it becomes blocked, thus ensuring the service life of the filter screen half-cylinder.

The spiral plate 205 is adapted to the cylindrical structure, and the pitch of the spiral plate 205 on the side near the drive component 201 is greater than the pitch on the side away from the drive component 201.

[0034] like Figure 1 , Figure 2 and Figure 6 As shown, the auxiliary cleaning component 3 includes a connecting plate 301, a meshing tooth 302, a slider 303, an elastic element 304, and a scraper 305.

[0037] The work process is as follows:

[0038] S1. When using, the leftover vegetables that need to be dehydrated are added from the feed hopper 109 into the cylindrical structure composed of the connecting half-cylinder 103 and the filter half-cylinder 104;

[0039] S2. Start the drive unit 201. The drive unit 201 drives the connecting shaft 202 to rotate through the coupling 203. The connecting shaft 202 drives the spiral plate 205 to rotate. As the spiral plate 205 moves the tail vegetable, the pitch of the spiral plate 205 gradually decreases, and the radius of the cylindrical structure formed by the connecting half-cylinder 103 and the filter half-cylinder 104 gradually decreases, thus squeezing and dehydrating the tail vegetable.

[0040] S3. The water squeezed out from the vegetable waste flows out through the feed pipe 106. The dehydrated vegetable waste falls into the receiving box 5 from the feed port 105. The discharge baffle 402 is moved by the drive rod 401, which can adjust the distance between the discharge baffle 402 and the discharge end of the cylindrical structure composed of the connecting half-cylinder 103 and the filter half-cylinder 104, thereby adjusting the discharge speed.

[0041] S4. While dehydrating the leftover vegetables, the connecting shaft 202 drives the eccentric incomplete gear 204 to rotate. The eccentric incomplete gear 204 drives the connecting plate 301 through the meshing teeth 302. The connecting plate 301 drives the slider 303 to slide on the connecting shell 101.

[0042] S5. When the eccentric incomplete gear 204 no longer meshes with the meshing tooth 302, the elastic element 304 rebounds, causing the slider 303 to slide on the connecting shell 101. This reciprocating motion causes the slider 303 to drive the scraper 305 to clean the fine fibers wrapped around the filter screen half-cylinder 104, preventing the fine fibers of the vegetable waste from getting tangled up and causing the filter screen half-cylinder 104 to become clogged, preventing water from the vegetable waste from penetrating and affecting the dehydration effect. At the same time, it also prevents the filter screen half-cylinder 104 from being subjected to greater compressive force after it becomes clogged, thus ensuring the service life of the filter screen half-cylinder 104.

[0043] S6. When it is necessary to backwash the filter screen half-cylinder 104, the backwash water enters from the flushing pipe 107 and sprays out from the nozzle 108 to backwash and clean the filter screen half-cylinder 104.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
