Description

Technical Field

[0001] This utility model belongs to the field of kitchen waste treatment technology, specifically relating to a solid-liquid separation device for kitchen waste sewage treatment. Background Technology

[0002] Kitchen waste, also known as wet waste or organic waste, mainly refers to the waste generated in daily life, food processing, catering services, and institutional catering activities. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets, and other food processing-related industries. Kitchen wastewater treatment is an important part of the kitchen waste treatment process. After the kitchen waste is transported to the treatment station, it first undergoes secondary sorting to remove debris such as stones and plastics. Then, the waste is crushed, sorted, and dehydrated through physical methods to achieve solid-liquid separation. The separated oil can be made into clean energy such as biodiesel, while the wastewater is directly transported to the sewage treatment plant for further treatment through the pipeline system.

[0003] Chinese patent CN211836697U discloses a solid-liquid separation device for kitchen waste, comprising a shell, a cover, a compression assembly, and a spin-drying assembly. The shell includes an outer shell and an inner cylinder, with the inner cylinder fitted inside the outer shell. The inner cylinder has a universal ball joint, a bottom hole on its bottom surface, and side holes on its sides. The upper part of the outer shell has a fixed wall, and the lower part has an inclined surface. One side of the outer shell has a water outlet. A filter screen is provided between the inner cylinder and the inclined surface. The compression assembly includes a pressure plate, a pressure rod, and a pressure rod motor. The pressure plate and the rotating motor are connected through the pressure rod. There are two pressure rods, and the center of the pressure plate has a through hole. The spin-drying assembly includes a rotating motor and a rotating shaft. The cover has a control switch and a microwave tube. Both the pressure rod motor and the rotating motor are located inside the cover. This invention solves the problems of large volume of kitchen waste and the presence of a lot of wastewater in kitchen waste, making recycling difficult, and is applicable to most situations.

[0004] However, while the above-mentioned technical solution can achieve the purpose of solid-liquid separation of kitchen waste, after the solid-liquid separation is completed, some solid waste needs to be squeezed. The squeezed solid waste needs to be manually removed by the staff, which is cumbersome. The solid waste is squeezed and formed inside the inner cylinder, which is inconvenient for the staff to remove from the top. It is also difficult for the staff to remove the solid waste directly. The staff needs to repeatedly empty the inner cylinder, which is laborious and time-consuming, and affects the progress of subsequent solid-liquid separation of kitchen waste. Therefore, it has certain limitations in use. Utility Model Content

[0024] Example 1:

[0025] Please see Figures 1 to 5As shown, a solid-liquid separation device for treating kitchen waste sewage includes a housing 1. A connecting ring 2 is fixedly connected to one side of the top of the housing 1. A slot is formed at the bottom of the surface of the housing 1, and a drain port 3 passes through the slot.

A fixing strip 12 is fixedly connected to the bottom of the inner wall of the annular cavity 4, and the bottom end of the threaded rod 7 is rotatably disposed inside the fixing strip 12. An electric push rod 8 is rotatably disposed on the surface of the threaded sleeve. A bearing block 9 is fixedly connected to the output end of the push rod 8. A protective shell is fixedly connected to the top of the bearing block 9. A first drive motor 10 is fixedly connected inside the protective shell. A transmission rod is fixedly connected to the output end of the first drive motor 10. A base plate 11 is rotatably mounted on the surface of the transmission rod. An electric slide rail 23 is fixedly connected to the inner bottom wall of the box 1. An electric slider is slidably connected inside the electric slide rail 23. A guide tube 22 is fixedly connected to the top of the electric slider. A collection hopper 21 is fixedly connected to the top of the guide tube 22.

A discharge port 25 is opened at the bottom of the back of the box 1, and the surface of the guide plate 24 penetrates the interior of the discharge port 25.

[0026] The drain outlet 3 facilitates the discharge of wastewater from kitchen waste. The clearance groove 5 facilitates the subsequent storage of the bottom plate 11. The servo motor 6 provides a certain driving force for the rotation of the threaded rod 7. The rotation of the threaded rod 7 drives the threaded sleeve to move left and right, which in turn causes the electric push rod 8 to move left and right. The electric push rod 8 drives the bearing block 9 to move up and down, which in turn adjusts the height of the first drive motor 10. The electric slide rail 23 allows the electric slider to drive the guide tube 22 to move left and right, thereby causing the collection hopper 21 to move left and right. The discharge port 25 facilitates the passage of the guide plate 24 inside. The fixed strip 12 has a small diameter, which prevents the accumulation of impurities.

[0027] The surface of the connecting ring 2 is threaded with a stabilizing seat 13. A protective cavity is fixedly connected to the middle of the top of the stabilizing seat 13. A second drive motor 14 is fixedly connected inside the protective cavity. A transmission plate 15 is fixedly connected to the output end of the second drive motor 14. A snap-fit ​​rod 16 is fixedly connected to both sides of the bottom of the transmission plate 15. A release cavity 17 is provided on the square of the stabilizing seat 13.

Several first water outlet holes 26 are opened inside the release cavity 17. The stabilizing base 13 is set so that it can be connected to the connecting ring 2. The second drive motor 14 is set so that it provides a certain driving force for the rotation of the transmission plate 15, thereby driving the locking rod 16 to rotate. The surface of the locking rod 16 penetrates the interior of the locking hole. It should be noted that the locking rod 16 is also fixedly connected to both sides of the top of the base plate 11. The bottom of the release chamber 17 is hollowed out, and locking holes are also opened on both sides of the bottom, so that the base plate 11 can be rotated when the release chamber 17 rotates.

[0028] A hydraulic telescopic rod 18 is fixedly connected to the middle of the bottom of the transmission plate 15, and a pressing disc 19 is fixedly connected to the output end of the hydraulic telescopic rod 18. The hydraulic telescopic rod 18 is provided with a certain power to press down the pressing disc 19, which facilitates the pressing of solid kitchen waste inside the cavity 17 into shape.

[0029] A positioning block is fixedly connected to the bottom end of the surface of the annular cavity 4. An electric telescopic rod 20 is fixedly connected to the bottom of the positioning block. A blocking block is fixedly connected to the output end of the electric telescopic rod 20, and the surface of the blocking block penetrates the interior of the relief groove 5. The electric telescopic rod 20 can drive the blocking block to descend, thereby blocking the relief groove 5 and preventing sewage from being thrown into the interior of the relief groove 5 when the cavity 17 is rotated. Several through holes are opened on the inner bottom wall of the fixing strip 12 to facilitate the discharge of sewage.

[0030] The output end of the first drive motor 10 is fixedly connected to an adjustment plate 27, and the adjustment plate 27 is rotatably disposed inside the base plate 11, and the base plate 11 has several second water outlet holes 28.

[0031] Several connecting rods 29 are fixedly connected to the surface of the adjusting disc 27. A sealing block 30 is fixedly connected to the surface of each connecting rod 29, and the surface of the sealing block 30 extends through the interior of the second water outlet 28. The adjusting disc 27 is driven by the first drive motor 10, which in turn drives the connecting rods 29 to rotate, subsequently driving the sealing block 30 to rotate to the position of the second water outlet 28, thus sealing it. The first drive motor 10 rotates by the distance from one set of sealing blocks 30 connected by the connecting rods 29 to the adjacent second water outlet 28, allowing wastewater to drip downwards from the second water outlet 28.

[0032] A stabilizing strip 31 is connected to the inner wall of the drain outlet 3. A filter plate 32 is fixedly connected to one side of the stabilizing strip 31 via two connecting short rods. A fastening bolt is threaded inside the drain outlet 3, and the thread of the fastening bolt penetrates the interior of the stabilizing strip 31. An observation port is provided on one side of the housing 1. A control panel is fixedly connected to the top of the housing 1, and the control panel is electrically connected to the servo motor 6, the electric push rod 8, the first drive motor 10, the second drive motor 14, the hydraulic telescopic rod 18, and the electric telescopic rod 20. The stabilizing strip 31 facilitates the fixing of the filter plate 32, which can block impurities contained in the sewage. The fastening bolts fix the stabilizing strip 31 inside the drain outlet 3 and facilitate subsequent disassembly. The observation port allows personnel to observe the inside of the housing 1. Several water outlet holes are provided inside the stabilizing strip 12 to facilitate the discharge of sewage.

[0033] The working principle of this utility model is as follows: When the worker needs to process kitchen waste, the stabilizing seat 13 is unscrewed to separate it from the connecting ring 2. The kitchen waste is then poured into the release chamber 17 inside the container 1. The stabilizing seat 13 is then reconnected to the connecting ring 2. During this process, the positions of the locking rod 16 and the locking hole are carefully monitored, ensuring the locking rod 16 is inserted into the locking hole. At this point, the squeezing disc 19 and other structures enter the release chamber 17. The worker then controls the second drive motor 14 to operate. The output of the second drive motor 14 drives the transmission plate 15 to rotate, which in turn drives the locking rod 16 to rotate, thus causing the release chamber 17 to rotate. The bottom of the separation chamber 17 is connected to the threaded sleeve via an electric push rod 8, allowing it to rotate. This rotation causes the separation chamber 17 to rotate, throwing out wastewater through centrifugal force. The thrown-out wastewater enters the guide pipe 22 through the collection hopper 21, then passes through the guide pipe 22 and enters the drain outlet 3. Impurities in the wastewater are blocked by the filter plate 32 and discharged through the outlet hole. At this time, the operator controls the hydraulic telescopic rod 18 to work. The output end of the hydraulic telescopic rod 18 drives the extrusion plate 19 to descend, which compresses the solid waste inside the separation chamber 17, shaping it. Then, the operator controls the electric push rod 8 to descend, which in turn drives the bottom... The locking rods 16 on both sides of the top of plate 11 disengage from the locking holes at the bottom of the release chamber 17. Then, the operator starts the servo motor 6, whose output drives the threaded rod 7 to rotate, causing the threaded sleeve to move to the left. This, in turn, moves the bottom plate 11 to the left, causing the collection hopper 21 to move away from below the release chamber 17. At this point, the guide plate 24 moves below the release chamber 17, allowing the compressed solid waste to be discharged through the guide plate 24 and finally through the discharge port 25. The operator can then collect the waste using a collection device. During the compression of kitchen waste, the operator can start the first drive motor 10. The output of motor 10 drives the adjustment plate 27 to rotate, which in turn drives the connecting rod 29 and the sealing block 30 to rotate, moving them to the position of the second water outlet 28. This prevents solid kitchen waste from clogging the inside of the second water outlet 28. Some of the solid waste squeezed into the first water outlet 26 can be thrown out by centrifugal force and enter the collection hopper 21, where it is finally blocked by the filter plate 32 for subsequent centralized processing. After the work is completed, the staff can unscrew the stabilizing seat 13 and remove it. At this time, the separation chamber 17 can be removed and cleaned. The annular chamber 4 and the inside of the collection hopper 21 can also be rinsed with clean water for subsequent use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
