Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, specifically a kitchen waste slurry removal and sorting device. Background Technology

[0002] Food waste refers to organic waste generated during food processing, catering services, and household life. Food waste includes organic solids, oils, and water. Depending on the composition of food waste, there are currently various treatment methods, such as composting, anaerobic fermentation, feed production, and incineration.

[0003] Taking anaerobic fermentation as an example, kitchen waste has a complex composition, containing various impurities in addition to most organic matter, requiring pretreatment before it can enter anaerobic fermentation. Although it has undergone a series of pretreatment processes such as screening, crushing, pulping, and sand removal, it still falls short of the material requirements for anaerobic fermentation and needs to undergo further processing such as impurity removal. Chinese Patent Announcement CN220715129 U discloses a kitchen waste slurry impurity removal device, including a feed pipe, a processing box fixedly installed on one side of the feed pipe, a sealing door body at one end of the processing box, an observation window at one end of the sealing door body, a filter plate fixedly installed on the inner wall of the processing box, a motor box fixedly installed at the lower end of the filter plate, a servo motor fixedly installed on the inner wall of the motor box, a sedimentation tank fixedly installed at the lower end of the processing box, and a slurry outlet pipe fixedly installed in the middle of one end of the sedimentation tank.

[0004] The aforementioned kitchen waste slurry impurity removal device uses a filter plate to filter large particles in the slurry, while small particles settle in a sedimentation tank, thus achieving the effect of impurity removal. However, the filter plate of this device is located inside the processing tank. As more and more slurry is filtered, more and more impurities accumulate on the filter plate. When the impurities accumulate to the point of completely covering the filter plate, the slurry cannot pass through, causing the slurry filtration process to malfunction. Furthermore, the processing tank is a one-piece design, so the impurities on the filter plate cannot be discharged in time. It is necessary to stop the impurity removal device and disassemble the processing tank to remove the impurities, which not only increases the difficulty of cleaning impurities but also reduces the efficiency of slurry impurity removal.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In this utility model, the auger roller can uniformly transport the slurry in the feed hopper into the outer cylinder, preventing the slurry from accumulating in the feed pipe. The drive shaft drives the auger roller to rotate, which in turn drives the connecting sleeve to rotate, thereby causing multiple scrapers to rotate. During the rotation, the scrapers rapidly agitate the slurry, dispersing it evenly in the outer cylinder. In addition, the rapidly rotating scrapers generate centrifugal force, causing the slurry to adhere tightly to the inner wall of the outer cylinder. At this time, the slurry flows out of the outer cylinder through the trough and enters the space between the outer cylinder and the outer shell. At the same time, the scrapers also squeeze the slurry, increasing the speed of the slurry passing through the trough, thereby increasing the efficiency of slurry impurity removal. The slurry enters the transport pipe through the discharge hopper at the bottom of the outer shell, while impurities blocked by the trough remain in the outer cylinder, achieving separation of slurry and impurities.

[0021] 2. In this invention, as the auger roller continuously transports the slurry into the outer cylinder, the amount of impurities in the outer cylinder increases. At this time, the impurities near the end of the auger roller in the outer cylinder will push the remaining impurities towards the screw conveyor and eventually move to the transfer bin. Then, the impurities fall into the screw conveyor body through the extension pipe of the transfer bin, and the screw conveyor body transfers the impurities to the collection hopper for centralized processing. The impurities are transferred during the slurry impurity removal process without the need for work stoppage or manual assistance, which reduces the difficulty of slurry impurity removal and increases the efficiency of slurry impurity removal.

[0022] 3. In this utility model, after the slurry is cleaned, a certain amount of slurry residue will remain on the inner wall of the outer shell and the outer cylinder. At this time, by opening the valve, multiple spray heads will spray clean water to clean the inner wall of the outer shell and the outer cylinder, which can remove the residual slurry, thereby ensuring the cleanliness of the outer shell and the outer cylinder, preventing the groove of the outer cylinder from being blocked by hardened slurry residue, and extending the service life of the outer cylinder and the scraper.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1-13 In this embodiment of the utility model, the kitchen waste slurry impurity removal and sorting device includes an impurity separator 1. The feed end of the impurity separator 1 is fixedly connected to the receiving bin, the slurry discharge end is fixedly connected to the transport pipeline 6, and the impurity discharge end is equipped with a screw conveyor 3. The impurity separator 1 is equipped with a rinsing device 2, and one end of the impurity separator 1 is equipped with a controller 4.

[0041] The impurity separator 1 includes a centrifugal separation component 14, one end of which is fixedly connected to the transfer chamber 16 and the other end is fixedly connected to the feed pipe 12. The bottom of the centrifugal separation component 14 is welded to the top of the discharge hopper 15, and the bottom of the discharge hopper 15 is fixedly connected to the transport pipe 6. A drive mechanism 13 is provided at the end of the feed pipe 12 away from the centrifugal separation component 14. The top of the feed pipe 12 is fixedly connected to the feed hopper 11.

[0042] The centrifugal separation assembly 14 includes an outer cylinder 146, on which a plurality of annularly distributed grooves 143 are uniformly provided; a connecting sleeve 144 is coaxially provided on the inner side of the outer cylinder 146, and a plurality of scrapers 145 are uniformly fixedly connected to the outer side of the connecting sleeve 144, and the plurality of scrapers 145 are located on the inner side of the outer cylinder 146.

[0043] The outer cylinder 146 is provided with an outer shell 141. The bottom of the outer shell 141 is fixedly connected to the top of the discharge hopper 15, and the space inside the outer shell 141 is connected to the discharge hopper 15. An observation door 142 is movably connected to the outer shell 141 via a hinge. One end of the outer shell 141 near the screw conveyor 3 is fixedly connected to the transfer chamber 16, and the other end is fixedly connected to the end of the feed pipe 12.

[0044] The transfer chamber 16 is integrally provided with an extension pipe at its bottom, which is connected to the interior of the transfer chamber 16; the feed pipe 12 is connected to the outer cylinder 146, the feed hopper 11 is connected to the feed pipe 12, and the drive mechanism 13 is located at the end of the feed pipe 12 away from the outer cylinder 146.

[0045] By adopting the above technical solution, the auger roller 136 can uniformly transport the slurry in the feed hopper 11 into the outer cylinder 146, preventing the slurry from accumulating in the feed pipe 12. The drive shaft 135 drives the auger roller 136 to rotate, simultaneously driving the connecting sleeve 144 to rotate, thereby causing multiple scrapers 145 to rotate. During rotation, the scrapers 145 rapidly agitate the slurry, dispersing it evenly in the outer cylinder 146. Furthermore, the rapidly rotating scrapers 145 generate centrifugal force, further dispersing the slurry... The material is tightly adhered to the inner wall of the outer cylinder 146. At this time, the slurry will flow out of the outer cylinder 146 through the trough 143 on the outer cylinder 146 and enter the space between the outer cylinder 146 and the outer shell 141. At the same time, the scraper 145 also has the effect of squeezing the slurry, increasing the speed of the slurry through the trough 143, thereby increasing the efficiency of slurry impurity removal. The slurry enters the transport pipe 6 through the discharge hopper 15 at the bottom of the outer shell 141. The impurities blocked by the trough 143 remain in the outer cylinder 146, realizing the separation of slurry and impurities.

[0046] In this embodiment, the drive mechanism 13 includes a drive shaft 135, which is located inside the outer cylinder 146 and the feed pipe 12 and is coaxially arranged with the outer cylinder 146 and the feed pipe 12; the connecting sleeve 144 is fixedly connected to the drive shaft 135; one end of the drive shaft 135 is rotatably connected to the transfer chamber 16 and the other end is rotatably connected to the protective shell 137.

[0047] The drive shaft 135 is coaxially and fixedly connected to the auger roller 136 at one end near the feed pipe 12. The auger roller 136 is located inside the feed pipe 12. A driven pulley 133 is fixedly connected to the drive shaft 135 at one end near the auger roller 136. A driving pulley 132 is provided below the driven pulley 133, and the driving pulley 132 is connected to the driven pulley 133 through a belt 134.

[0048] The middle of the driving pulley 132 is fixedly connected to the output shaft of the motor 131; the driving pulley 132, the driven pulley 133 and the belt 134 are all located inside the protective shell 137. The upper end of the protective shell 137 is fixedly connected to the end of the feed pipe 12 away from the outer cylinder 146, and the motor 131 is fixedly connected to the lower end of the protective shell 137.

[0049] The bottom of the outer shell 141 and the upper end of the discharge hopper 15 are both fixedly connected to the bracket 5, and the discharge hopper 15 and the transport pipe 6 are both located inside the bracket 5; a controller 4 is provided at the end of the bracket 5 away from the screw conveyor 3.

[0050] By adopting the above technical solution, as the auger roller 136 continuously transports the slurry into the outer cylinder 146, the impurities in the outer cylinder 146 increase. At this time, the impurities near the end of the auger roller 136 in the outer cylinder 146 will push the remaining impurities towards the screw conveyor 3, and eventually move to the transfer chamber 16. Then, the impurities fall into the screw conveyor body 31 through the extension pipe of the transfer chamber 16, and the screw conveyor body 31 transfers the impurities to the collection hopper for centralized processing. The transfer of impurities is realized in the process of removing impurities from the slurry without stopping work or manual assistance, which reduces the difficulty of the slurry impurity removal work and increases the efficiency of the slurry impurity removal work.

[0051] In this embodiment, the flushing device 2 includes a main pipe 21, one end of which is fixedly connected to a water supply device, and the other end is integrally provided with two branch pipes 23. A valve 22 is installed at the end of the main pipe 21 away from the branch pipes 23. Multiple spray heads 24 are evenly provided on the side of the two branch pipes 23 near the outer shell 141. The multiple spray heads 24 are all located inside the outer shell 141. Supports 25 are fixedly connected to both ends of the two outer shells 141. The bottom of the multiple supports 25 is fixedly connected to the outer wall of the outer shell 141.

[0052] The screw conveyor 3 includes a screw conveyor body 31, which is inclined and has a support frame 32 fixedly connected to both ends of the screw conveyor body 31.

[0053] The screw conveyor body 31 includes a straight cylinder 311. The top of the end of the straight cylinder 311 near the transfer chamber 16 is provided with an inlet groove 312, and the position of the inlet groove 312 corresponds to the position of the extension pipe of the transfer chamber 16. The bottom of the end of the straight cylinder 311 away from the transfer chamber 16 is provided with an outlet groove 313, and a collection hopper is provided below the outlet groove 313. The straight cylinder 311 is coaxially provided with a second auger roller 314. The two ends of the second auger roller 314 are respectively rotatably connected to the two ends of the straight cylinder 311, and the end of the second auger roller 314 is fixedly connected to the motor unit 315.

[0054] By adopting the above technical solution, after the slurry is cleaned, a certain amount of slurry residue will remain on the inner wall of the outer shell 141 and the outer cylinder 146. At this time, by opening the valve 22, multiple spray heads 24 spray clean water to clean the inner wall of the outer shell 141 and the outer cylinder 146, which can remove the residual slurry, thereby ensuring the cleanliness of the outer shell 141 and the outer cylinder 146, preventing the groove 143 of the outer cylinder 146 from being blocked by hardened slurry residue, and extending the service life of the outer cylinder 146 and the scraper 145.

[0055] The working principle of this utility model is as follows: the auger roller 136 can uniformly transport the slurry in the feed hopper 11 into the outer cylinder 146, preventing the slurry from accumulating in the feed pipe 12; the drive shaft 135 drives the auger roller 136 to rotate, and at the same time drives the connecting sleeve 144 to rotate, thereby causing multiple scrapers 145 to rotate. During the rotation, the multiple scrapers 145 rapidly agitate the slurry, allowing the slurry to be evenly dispersed in the outer cylinder 146. In addition, the rapidly rotating scrapers 145 also generate centrifugal force, allowing... The slurry adheres tightly to the inner wall of the outer cylinder 146. At this time, the slurry flows out of the outer cylinder 146 through the trough 143 and enters the space between the outer cylinder 146 and the outer shell 141. At the same time, the scraper 145 also squeezes the slurry, increasing the speed of the slurry through the trough 143, thereby increasing the efficiency of slurry impurity removal. The slurry enters the transport pipe 6 through the discharge hopper 15 at the bottom of the outer shell 141. Impurities blocked by the trough 143 remain in the outer cylinder 146, realizing the separation of slurry and impurities.

[0056] As the auger roller 136 continuously transports the slurry into the outer cylinder 146, the impurities in the outer cylinder 146 increase. At this point, the impurities near the end of the auger roller 136 in the outer cylinder 146 will push the remaining impurities towards the screw conveyor 3, and eventually move to the transfer chamber 16. Then, the impurities fall into the screw conveyor body 31 through the extension pipe of the transfer chamber 16, and the screw conveyor body 31 transfers the impurities to the collection hopper for centralized processing. The transfer of impurities is achieved during the slurry impurity removal process without the need for work stoppage or manual assistance, which reduces the difficulty of slurry impurity removal and increases the efficiency of slurry impurity removal.

[0057] After the slurry is cleaned, a certain amount of slurry residue will remain on the inner wall of the outer shell 141 and the outer cylinder 146. At this time, by opening the valve 22, multiple spray heads 24 spray clean water to clean the inner wall of the outer shell 141 and the outer cylinder 146, which can remove the residual slurry, thereby ensuring the cleanliness of the outer shell 141 and the outer cylinder 146, preventing the groove 143 of the outer cylinder 146 from being blocked by hardened slurry residue, and extending the service life of the outer cylinder 146 and the scraper 145.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
