Description

Technical Field

[0001] This utility model relates to the field of dehydration device technology, specifically a centrifugal dehydration device for kitchen waste that avoids clogging. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and unit catering activities. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones (chicken bones, fish bones, etc.). Its main sources are family kitchens, restaurants, hotels, canteens, markets, and other food processing-related industries. Kitchen waste is often mixed with oil and water, which makes it take up a lot of volume. When cleaning kitchen waste, it is necessary to clean the oil and water mixed in with the waste. The traditional cleaning method is to centrifuge the waste to remove the oil and water. However, centrifugation can easily cause the holes on the surface of the dehydration bucket to become clogged, which is inconvenient to clean and ultimately affects the dehydration effect. In order to improve this situation, a kitchen waste centrifugal dehydration device that avoids clogging is proposed.

[0003] As disclosed in the patent announcement CN222709904U, a rapid dewatering device for kitchen waste includes a vortex base; a dewatering machine outer cylinder is installed on the top of the vortex base, and an upper top flange cover is fixedly connected to the top of the dewatering machine outer cylinder. An inlet is located at the center of the upper top flange cover, and a drain outlet is located on one side of the vortex base; a hollow feed shaft is provided inside the dewatering machine outer cylinder, with its upper part passing through the center of the upper top flange cover and connected to the inlet via a bearing; a brush auger hollow screw is installed on the hollow feed shaft located inside the dewatering machine outer cylinder; and a feed shaft drive shaft is connected to the bottom of the hollow feed shaft, which passes through the vortex base.

[0004] While it effectively separates solid and liquid waste from food waste, preventing residue from clogging the outer cylinder of the dewatering machine and avoiding waste buildup in the drainage pipes, it doesn't solve the problems of existing dewatering devices that hinder the up-and-down movement of the screen to scrape and clean residue from the mesh, or the comprehensive cleaning of the inner cylinder. It also doesn't allow for automatic opening and closing of the lid for inspection, thus affecting the centrifugal dewatering effect of food waste. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal dewatering device for kitchen waste that avoids clogging, thereby solving the problems mentioned in the background art, such as the inconvenience of moving the dewatering device up and down to scrape and clean the residue in the mesh and to clean the inner cylinder in all directions, the difficulty of automatically opening and closing the lid to inspect the inside, and the impact on the centrifugal dewatering effect of kitchen waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal dewatering device for kitchen waste that avoids clogging, comprising a base and an outer barrel. The outer barrel is mounted on the top of the base, and a mesh inner cylinder is movably installed inside the outer barrel. Cylinders are symmetrically arranged on the outer wall of the outer barrel. An integrated frame is mounted on the outer wall of the outer barrel on one side of each cylinder. A push arm is mounted on the output end of each cylinder. A barrel cover is mounted on the top of the outer barrel, and a feed inlet is located on the top of the barrel cover. A drive seat is located above the barrel cover, and the push arm is connected to the drive seat. A transfer frame is located on the top of the drive seat. An adapter sleeve is provided at the center of the adapter frame. A flexible hose is provided at the top of the adapter sleeve. A hollow shaft is provided inside the adapter sleeve and is movably connected to the adapter sleeve. The hollow shaft extends through the drive seat and into the interior of the mesh inner cylinder. A third servo motor is provided on the side wall of the drive seat. A worm gear is installed at the output end of the third servo motor. A worm wheel is fitted on the surface of the hollow shaft on one side of the worm gear, and the worm gear and the worm wheel mesh with each other. Brush scrapers are symmetrically arranged on the surface of the hollow shaft. Multiple sets of nozzles are provided on the surface of the hollow shaft on one side of the brush scraper, and the nozzles are connected to the hollow shaft.

[0007] Preferably, a first servo motor is provided at the top of the base on one side of the outer barrel, and a pulley assembly is provided at the output end of the first servo motor.

[0008] Preferably, the bottom of the outer barrel is provided with two sets of liquid discharge ports, and the bottom of the mesh inner barrel is provided with a slag discharge port.

[0009] Preferably, the slag discharge port is movably connected to the outer barrel, and the pulley assembly extends to the surface of the slag discharge port.

[0010] Preferably, each of the integrated frames is provided with a lead screw, and the lead screw is movably connected to the integrated frame.

[0011] Preferably, a second servo motor is provided at the bottom of each integrated frame, and the output end of the second servo motor is connected to the lead screw.

[0012] Preferably, the surface of the lead screw is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw.

[0013] Preferably, each threaded sleeve is provided with a connecting bracket on its side wall, and the connecting bracket is connected to the bucket lid.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this dewatering device not only realizes the up-and-down movement to scrape and clean the residue inside the mesh and to clean the inner cylinder in all directions, but also facilitates the automatic opening and closing of the lid to complete the internal inspection, avoids the situation of residue clogging the inner cylinder, reduces labor costs, and improves the centrifugal dewatering effect of kitchen waste:

[0015] (1) The first servo motor drives the pulley assembly to move, and the pulley assembly drives the slag discharge port to rotate. With the movement of the mesh inner cylinder and the outer barrel, the slag discharge port drives the mesh inner cylinder to rotate inside the outer barrel. The mesh inner cylinder drives the garbage inside to rotate centrifugally. Under the action of centrifugal force, the oil and water mixed in the garbage are thrown into the outer barrel through the holes on the surface of the mesh inner cylinder and discharged through the drain port. At this time, food residue remains inside the mesh inner cylinder. When the valve inside the slag discharge port is opened, some residue will be discharged through the slag discharge port under its own gravity. However, some residue remains in the inner wall and holes of the mesh inner cylinder. The third servo motor drives the worm to rotate, and the worm drives the hollow shaft to rotate through the worm wheel. The hollow shaft drives the brush scraper to rotate. The brush scraper cleans the residue remaining on the inner wall and in the holes of the mesh inner cylinder. The cleaned residue falls freely through the slag discharge port. The cylinder drives the push arm to retract, which in turn moves the drive seat, hollow shaft, and brush scraper downwards. The brush scraper then cleans the inner wall and holes of the mesh inner cylinder from top to bottom, thoroughly removing residue and preventing clogging. Afterwards, the cylinder reverses direction, resetting the brush scraper. A flexible hose is then connected to the external cleaning solution. Water from the external source enters the nozzle through the flexible hose, adapter sleeve, and hollow shaft, spraying out onto the inner wall of the mesh inner cylinder to rinse it. This process is repeated, moving the brush scraper downwards again, working with the cleaning solution to thoroughly clean the inner cylinder. This method achieves both vertical and horizontal scraping to remove residue from the mesh and comprehensive cleaning of the inner cylinder, preventing clogging and improving the centrifugal dehydration effect of food waste.

[0016] (2) The second servo motor drives the lead screw to rotate, and the lead screw drives the connecting frame to move upward through the threaded sleeve. The connecting frame drives the bucket lid to move upward, so as to open the bucket lid. Then, the outer bucket and the inner cylinder of the mesh can be inspected. This reduces the need for manual opening and closing of the bucket lid, reduces manpower expenditure, and saves human resources. Attached Figure Description

[0027] Example 1

[0028] Please see Figure 1-6This utility model provides an embodiment of a centrifugal dewatering device for kitchen waste that avoids clogging. It includes a base 1 and an outer barrel 4. The outer barrel 4 is located at the top of the base 1. A mesh inner cylinder 10 is movably installed inside the outer barrel 4. Cylinders 6 are symmetrically arranged on the outer wall of the outer barrel 4, providing power drive. An integrated frame 5 is provided on the outer wall of the outer barrel 4 on one side of each cylinder 6. A push arm 15 is installed at the output end of each cylinder 6. A barrel cover 7 is located at the top of the outer barrel 4, with a feed inlet 8 at the top of the cover 7. A drive seat 16 is located above the cover 7, and the push arm 15 is connected to the drive seat 16. An adapter frame 18 is located at the top of the drive seat 16, and an adapter sleeve 19 is located at the center of the adapter frame 18. The top of the adapter sleeve 19 is provided with a flexible hose 20. The interior of the adapter sleeve 19 is provided with a hollow shaft 17, which is movably connected to the adapter sleeve 19. The hollow shaft 17 extends through the drive seat 16 into the interior of the mesh inner cylinder 10. A third servo motor 25 is provided on the side wall of the drive seat 16. The third servo motor 25 plays the role of power drive. A worm gear 23 is installed at the output end of the third servo motor 25. A worm wheel 24 is fitted on the surface of the hollow shaft 17 on one side of the worm gear 23, and the worm gear 23 and the worm wheel 24 mesh with each other. Brush scrapers 22 are symmetrically arranged on the surface of the hollow shaft 17. Multiple sets of nozzles 21 are provided on the surface of the hollow shaft 17 on one side of the brush scraper 22, and the nozzles 21 are connected to the hollow shaft 17.

[0029] The top of the base 1 on one side of the outer barrel 4 is provided with a first servo motor 2, which plays the role of power drive. The output end of the first servo motor 2 is provided with a pulley assembly 3.

[0030] The bottom of the outer barrel 4 is provided with two sets of liquid discharge ports 26, and the bottom of the mesh inner barrel 10 is provided with a slag discharge port 9.

[0031] The slag discharge port 9 is movably connected to the outer barrel 4, and the pulley assembly 3 extends to the surface of the slag discharge port 9;

[0032] When it is necessary to dehydrate kitchen waste mixed with oil and water, the waste is poured into the inner mesh cylinder 10 through the feed inlet 8. The first servo motor 2 is turned on, which drives the pulley assembly 3 to move. The pulley assembly 3 drives the discharge port 9 to rotate. With the movement of the inner mesh cylinder 10 and the outer barrel 4, the discharge port 9 drives the inner mesh cylinder 10 to rotate inside the outer barrel 4. The inner mesh cylinder 10 causes the waste inside to rotate centrifugally. Under the action of centrifugal force, the oil and water mixed in with the waste are thrown into the outer barrel 4 through the holes on the surface of the inner mesh cylinder 10. The liquid is discharged from the drain port 26. At this time, food residue remains inside the mesh inner cylinder 10. Open the valve inside the slag discharge port 9. Some residue will be discharged through the slag discharge port 9 under its own gravity, but some residue will remain on the inner wall and in the holes of the mesh inner cylinder 10. At this time, the third servo motor 25 is turned on, and the third servo motor 25 drives the worm 23 to rotate. Under the mutual meshing of the worm 23 and the worm wheel 24, and the movable cooperation of the hollow shaft 17 and the adapter sleeve 19, the worm 23 drives the hollow shaft 17 to rotate through the worm wheel 24. The hollow shaft 17 drives the brush scraper 22 to rotate. The brush scraper 22 cleans the residue remaining on the inner wall and in the holes of the mesh inner cylinder 10. The cleaned residue falls freely and is discharged through the slag discharge port 9. The cylinder 6 is opened, which drives the push arm 15 to retract. The push arm 15 drives the drive seat 16, hollow shaft 17, and brush scraper 22 to move downward. During this movement, the brush scraper 22 scrapes and cleans the inner wall and holes of the mesh inner cylinder 10 from top to bottom, making the residue cleaner and preventing the residue from clogging the holes. Afterward, the cylinder 6 is opened in the reverse direction to reset the brush scraper 22. The flexible hose 20 is then connected to the external cleaning liquid. Water enters the nozzle 21 through the flexible hose 20, adapter sleeve 19, and hollow shaft 17, and is sprayed out onto the inner wall of the mesh inner cylinder 10 to rinse the inner wall of the mesh inner cylinder 10. The above operation is repeated, causing the brush scraper 22 to move from top to bottom again. In conjunction with the cleaning liquid, the inner cylinder 10 is cleaned in all directions to complete the cleaning work. This achieves the up-and-down movement of the scraper to clean the residue in the mesh and to clean the inner cylinder in all directions, avoiding the situation where the residue clogs the inner cylinder and improving the centrifugal dehydration effect of kitchen waste.

[0033] Each integrated frame 5 has a lead screw 12 inside, and the lead screw 12 is movably connected to the integrated frame 5. Each integrated frame 5 has a second servo motor 14 at its bottom, which serves as a power drive, and the output end of the second servo motor 14 is connected to the lead screw 12.

[0034] The surface of the lead screw 12 is fitted with a threaded sleeve 13, and the threaded sleeve 13 is threadedly connected to the lead screw 12. A connecting bracket 11 is provided on the side wall of the threaded sleeve 13, and the connecting bracket 11 is connected to the barrel cover 7.

[0035] When it is necessary to inspect the interior of the outer barrel 4 and the mesh inner barrel 10, the second servo motor 14 is turned on, which drives the lead screw 12 to rotate. With the lead screw 12 and the threaded sleeve 13 connected, the lead screw 12 drives the connecting frame 11 to move upward through the threaded sleeve 13. The connecting frame 11 then drives the barrel lid 7 to move upward, thereby opening the barrel lid 7. After that, the interior of the outer barrel 4 and the mesh inner barrel 10 can be inspected. This reduces the need for manual opening and closing of the barrel lid, reduces labor costs, and saves human resources.

[0036] Work steps

[0037] When it is necessary to dehydrate kitchen waste mixed with oil and water, the waste is poured into the inner mesh cylinder 10 through the feed inlet 8. The first servo motor 2 drives the pulley assembly 3 to move, which in turn drives the discharge port 9 to rotate. With the movement of the inner mesh cylinder 10 and the outer barrel 4, the discharge port 9 drives the inner mesh cylinder 10 to rotate inside the outer barrel 4. The inner mesh cylinder 10 causes the waste inside to rotate centrifugally. Under the action of centrifugal force, the oil and water mixed in with the waste are thrown through the holes on the surface of the inner mesh cylinder 10 into the outer barrel 4 and discharged through the drain port 26. At this point, food residue remains inside the mesh inner cylinder 10. Opening the valve inside the slag discharge port 9 allows some residue to be discharged under its own weight. However, some residue remains on the inner wall and in the holes of the mesh inner cylinder 10. The third servo motor 25 drives the worm gear 23 to rotate, which in turn drives the hollow shaft 17 to rotate via the worm wheel 24. The hollow shaft 17 then drives the brush scraper 22 to rotate, cleaning the residue remaining on the inner wall and in the holes of the mesh inner cylinder 10. The cleaned residue falls freely through the slag discharge port 9 and is discharged. The cylinder 6 drives the push arm 15 to retract, which in turn drives the drive seat 16, hollow shaft 17, and brush scraper 22 to move downwards. The brush scraper 22 scrapes and cleans the inner wall and holes of the mesh inner cylinder 10 from top to bottom, removing residue more thoroughly and preventing clogging. Afterwards, the cylinder 6 is reversed, causing the brush scraper 22 to return to its original position. The flexible hose 20 is then connected to the external cleaning fluid. External water enters the nozzle 21 through the flexible hose 20, adapter sleeve 19, and hollow shaft 17, and is sprayed from the nozzle 21 onto the inner wall of the mesh inner cylinder 10 to clean the surface. The inner wall of the mesh inner cylinder 10 is rinsed, and then the above operation is repeated, so that the brush scraper 22 moves from top to bottom again. With the help of the cleaning fluid, the inner wall of the mesh inner cylinder 10 is thoroughly cleaned to complete the cleaning of the inner cylinder. When it is necessary to inspect the outer barrel 4 and the inside of the mesh inner cylinder 10, the second servo motor 14 drives the lead screw 12 to rotate. The lead screw 12 drives the connecting frame 11 to move upward through the threaded sleeve 13. The connecting frame 11 drives the barrel cover 7 to move upward to open the barrel cover 7. Then the inspection of the outer barrel 4 and the inside of the mesh inner cylinder 10 can be completed.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
