Description

Technical Field

[0001] This invention relates to the field of food waste recycling technology, and in particular to an environmentally friendly food waste recycling device for an intelligent food delivery system. Background Technology

[0002] Currently, tray return conveyor belts are being used more and more widely in large restaurants. After finishing their meals, diners place their tableware and trays on the conveyor belt, which is then transported to the dishwasher so that workers can sort them and put them in the dishwasher for washing. This reduces labor, eliminates the handling process, and improves work efficiency.

[0003] When the plates are transported to the dishwasher, workers need to empty the food waste from the plates or utensils into the food waste disposer or garbage container. The food waste disposer or garbage container is equipped with a filter plate to separate the solid and liquid components of the food waste for subsequent processing. However, as the number of times food waste is emptied increases, the filter plate becomes clogged, resulting in poor filtration. Workers need to remove and clean the filter plate, which reduces the efficiency of food waste recycling and processing.

[0004] Therefore, this application proposes an environmentally friendly recycling device for food waste from an intelligent food delivery system. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing an environmentally friendly recycling device for food waste in an intelligent food delivery system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly food waste recycling device for an intelligent food delivery system includes a separation box. Inside the separation box is a rotatable, mesh-like guide tube. A power shaft rotates inside the guide tube, and a spiral blade, cooperating with the guide tube, is fixed on the power shaft. A flushing pipe is installed at the top inner part of the separation box, and a spray hole is provided at the bottom of the flushing pipe. When the power shaft rotates clockwise, the guide tube remains stationary; when the power shaft rotates counterclockwise, the guide tube rotates synchronously with the power shaft. A crushing box is installed at the bottom of the separation box, and a crushing blade capable of crushing food waste is provided inside the crushing box. A guide tube opposite to the end of the guide tube is provided at the upper end of the crushing box, and a discharge door is provided at the lower side of one side of the crushing box.

[0007] Preferably, a motor is installed on the separation box, a drive shaft is fixed to the output end of the motor, a rotating cylinder is provided at the other end of the drive shaft, the drive shaft passes through the rotating cylinder and is rotatably connected to it, the drive shaft is fixedly connected to the power shaft, and a plurality of connecting rods arranged in a ring are fixed on the rotating cylinder, and the plurality of connecting rods are fixedly connected to the guide cylinder.

[0008] Preferably, a support plate is fixedly connected to the separation box, and a first one-way bearing is installed on the support plate. The outer ring of the first one-way bearing is fixed to the support plate, and the rotating cylinder passes through the inner ring of the first one-way bearing and is fixedly connected to it. When the power shaft rotates forward, the inner ring and outer ring of the first one-way bearing cannot rotate relative to each other; when the power shaft rotates in reverse, the inner ring and outer ring of the first one-way bearing rotate relative to each other.

[0009] Preferably, a rotating ring is rotatably connected to the outside of the rotating cylinder and the guide cylinder. The rotating ring has a feed inlet, and a tilting pipe is installed on the feed inlet. The tilting pipe passes through the upper end of the separation box and is fixed thereto.

[0010] Preferably, the other end of the separation box is open, and a switch door is installed in the opening. A drain pipe is installed on the switch door, and a control valve is installed on the drain pipe.

[0011] Preferably, the bottom of the separation box is fixed with a first support shell and a second support shell, the first support shell and the second support shell are located on both sides of the crushing box, and a horizontal plate is fixed on the first support shell and the second support shell, and the crushing box abuts against the upper end of the horizontal plate.

[0012] Preferably, a rotating shaft is provided through the crushing box, the first support shell, and the second support shell, the crushing blade is fixed on the outer surface of the rotating shaft, and a transmission wheel is fixed on both the drive shaft and the rotating shaft, and the two transmission wheels are connected by a transmission belt.

[0013] Preferably, the system further includes a liquid supply mechanism, which includes a circular plate fixed on a rotating shaft. A piston cylinder is fixed inside the second support shell, and a movable piston is slidably connected inside the piston cylinder. A connecting rod is hinged to the upper end of the movable piston, and the connecting rod is eccentrically hinged to the circular plate.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Solid-liquid separation of food waste is achieved through the synergistic action of the guide tube and the spiral blades. The spiral blades compress the waste during rotation, causing the liquid to permeate through the mesh wall of the guide tube to the bottom of the separation tank, effectively separating the solid and liquid components for easier subsequent processing.

[0017] 2. The rotation of the guide tube is controlled by the first one-way bearing. When the motor reverses, the guide tube and the spiral blade rotate synchronously.

The liquid supply mechanism utilizes the power of the rotating shaft inside the crushing chamber to drive the moving piston to reciprocate through a crank-slider mechanism, thereby realizing the extraction and transportation of clean water. No additional power source is required, which simplifies the device structure, reduces energy consumption, and embodies the design concept of energy conservation and environmental protection.

[0020] In summary, this invention achieves efficient solid-liquid separation of food waste. Simultaneously, the synchronous rotation of the guide tube and spiral blades, combined with the flushing pipe, automatically cleans the adhering waste on the inner wall of the guide tube, avoiding the clogging problem of traditional filter plates and significantly improving the efficiency of food waste recycling. Furthermore, the inclusion of a crushing blade allows for the crushing of solid waste, facilitating subsequent transportation and processing, further enhancing the practicality and environmental friendliness of the device.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Reference Figures 1-8 An environmentally friendly recycling device for food waste in an intelligent food delivery system is designed to achieve efficient solid-liquid separation of food waste through the coordinated action of the guide tube 14 and the spiral blade 30. At the same time, the rotation state of the guide tube 14 is controlled by the first one-way bearing, and in conjunction with the flushing pipe 20 and the crushing blade 12, the waste is cleaned, crushed and subsequently recycled, effectively solving the technical problems of easy clogging and low processing efficiency of traditional filter plates.

[0025] Specifically, the food waste recycling device in this embodiment includes a separation box 1. The separation box 1 is a rectangular box structure with an open top and a hollow interior. It is made of 304 stainless steel, possessing corrosion resistance and high strength, and can adapt to the humid and corrosive environment during food waste treatment. A guide cylinder 14 is horizontally arranged inside the separation box 1. The guide cylinder 14 is a cylindrical body with openings at both ends. Its wall adopts a mesh structure design with a mesh aperture of 2-5mm, which ensures smooth liquid penetration while intercepting larger solid waste particles. The axis of the guide cylinder 14 is aligned with the length direction of the separation box 1.

[0026] A drive shaft 35 is coaxially mounted inside the guide tube 14. The diameter of the drive shaft 35 is smaller than the inner diameter of the guide tube 14, with a gap reserved between them to accommodate food waste. A spiral blade 30 is welded to the drive shaft 35. The edge of the spiral blade 30 is tightly fitted to the inner wall of the guide tube 14, and the pitch of the spiral blade 30 gradually decreases from the feed end to the discharge end. This design allows the spiral blade 30 to exert a squeezing effect on the food waste when it rotates, promoting solid-liquid separation.

[0027] To achieve backwashing of the guide tube 14 from the outside and prevent solid waste from adhering and clogging the mesh, a flushing pipe 20 is fixedly installed on the inner top of the separation box 1 by bolts. The extension direction of the flushing pipe 20 is parallel to the axis of the guide tube 14, and multiple spray holes 21 are evenly opened at the bottom of the flushing pipe 20 along its length. The spray holes 21 are set towards the mesh wall of the guide tube 14, and the diameter of the spray holes 21 is 1-2mm to ensure that the sprayed water has sufficient impact force.

[0028] In this embodiment, the rotational coordination between the power shaft 35 and the guide tube 14 is achieved through the motor 6 and the first one-way bearing assembly. Specifically, the motor 6 is fixedly connected to one side of the outer wall of the separation box 1 via a motor mounting base. The motor 6 is a servo motor with forward and reverse rotation functions, and its output speed and direction can be precisely controlled by a controller (such as a PLC controller).

[0029] The output end of motor 6 is fixedly connected to drive shaft 29 via a coupling. Drive shaft 29 extends horizontally into the separation tank 1, and a rotating cylinder 33 is fitted onto the other end of drive shaft 29. The rotating cylinder 33 is not mesh-like and cannot filter liquid. Drive shaft 29 passes through the axis of rotating cylinder 33 and is rotatably connected to rotating cylinder 33 via bearings, ensuring that drive shaft 29 can rotate independently relative to rotating cylinder 33. The end of drive shaft 29 away from motor 6 is fixedly connected to power shaft 35 via a flange, enabling motor 6 to drive power shaft 35.

[0030] Multiple connecting rods 34 are evenly welded along the circumferential direction on the outer peripheral wall of the rotating cylinder 33. The end of the connecting rod 34 away from the rotating cylinder 33 is welded and fixed to the inner wall of the end of the guide cylinder 14, forming a rigid connection between the rotating cylinder 33 and the guide cylinder 14, ensuring that the rotating cylinder 33 can synchronously drive the guide cylinder 14 to rotate when it rotates. An annular space is formed between the rotating cylinder 33 and the guide cylinder 14, which is used for feeding kitchen waste.

[0031] To control the rotation of the guide tube 14, a support plate 17 is bolted to the inner wall of the separation box 1, and the support plate 17 is sealed to the inner wall of the separation box 1. The support plate 17 is located on the side of the rotating cylinder 33 near the motor 6, and a first one-way bearing is embedded in the support plate 17. The outer ring of the first one-way bearing is fixed in the mounting hole of the support plate 17 by an interference fit, and the end of the rotating cylinder 33 near the motor 6 passes through the inner ring of the first one-way bearing and is fixedly connected to the inner ring by an interference fit.

[0032] The selection of the first one-way bearing here must meet the following requirements: when the power shaft 35 rotates clockwise (i.e., the motor 6 rotates forward), the inner and outer rings of the first one-way bearing are locked and cannot rotate relative to each other. This restricts the rotation of the rotating cylinder 33 through the support plate 17, keeping the guide cylinder 14 stationary. When the power shaft 35 rotates counterclockwise (i.e., the motor 6 rotates in reverse), the inner and outer rings of the first one-way bearing are unlocked and can rotate relative to each other. At this time, the rotating cylinder 33 can rotate synchronously with the drive shaft 29, thereby driving the guide cylinder 14 to rotate synchronously with the power shaft 35.

[0033] To ensure a stable feeding of food waste into the separation box 1, a rotating ring 31 is rotatably fitted around the feeding end of the rotating drum 33 and the guide tube 14. The rotating ring 31 has an annular structure, and its inner wall is rotatably connected to the outer wall of the rotating drum 33 and the guide tube 14 through a bearing, ensuring that the rotating ring 31 remains stationary when the rotating drum 33 and the guide tube 14 rotate. A feeding port 32 is provided through the side wall of the rotating ring 31, and a tilting pipe 7 is welded and fixed at the feeding port 32. The upper end of the tilting pipe 7 penetrates the upper wall of the separation box 1 and is fixedly connected to the separation box 1 through a flange. The tilting pipe 7 is set through the top opening of the separation box 1. This arrangement will not affect the entry of food waste into the guide tube 14.

[0034] The other end of the separation chamber 1 (the end furthest from the motor 6) is open, and a hinged door 16 is installed at this opening. A sealing ring is provided between the door 16 and the edge of the opening of the separation chamber 1 to ensure the airtightness of the separation chamber 1 and prevent liquid leakage. A drain pipe 5 is installed through the lower part of the door 16, and the drain pipe 5 is connected to the inside of the separation chamber 1 to drain the liquid after solid-liquid separation. A control valve (such as a solenoid valve) is installed on the drain pipe 5, which can be controlled by a controller to open and close, so as to adjust the timing of drainage according to the liquid level in the separation chamber 1.

[0035] When it is necessary to clean the inner wall of the separator 1, open the drain pipe 5 and spray high-pressure water through the water pipe to rinse the inner wall of the separator 1.

[0036] To crush the solid waste after solid-liquid separation for easier subsequent recycling and transportation, a crushing box 9 is bolted to the bottom of the separation box 1. The crushing box 9 is located directly below the discharge end of the guide cylinder 14. A rotating shaft 11 is rotatably mounted through the crushing box 9, the first support shell 2, and the second support shell 3. The crushing blade 12 is fixed to the outer surface of the rotating shaft 11. A drive wheel 19 is fixed to both the drive shaft 29 and the rotating shaft 11, and the two drive wheels 19 are connected by a drive belt 18.

[0037] The two ends of the rotating shaft 11 are rotatably connected to the two side walls of the crushing box 9 via bearings. Multiple crushing blades 12 are uniformly welded along the length of the rotating shaft 11. The crushing blades 12 are arranged in a spiral pattern, which can fully shear and crush the solid waste falling into the crushing box 9 when the rotating shaft 11 rotates, breaking large pieces of waste into smaller particles.

[0038] A guide pipe 13 is welded and fixed to the upper end face of the crushing box 9. The guide pipe 13 has a trumpet-shaped structure, with its upper large-diameter end facing the discharge end of the guide cylinder 14, and its lower small-diameter end communicating with the interior of the crushing box 9. This is used to accurately guide the solid waste discharged from the guide cylinder 14 into the crushing box 9, preventing waste from scattering. A discharge port is opened at the lower side of the crushing box 9. A discharge door 15 is installed at the discharge port by a hinge. The connection between the discharge door 15 and the crushing box 9 is equipped with a sealing lock. When the crushed waste in the crushing box 9 accumulates to a certain amount, the discharge door 15 can be opened to discharge the waste for subsequent recycling.

[0039] To improve the stability of the device, a first support shell 2 and a second support shell 3 are welded and fixed to the bottom of the separation box 1. The first support shell 2 and the second support shell 3 are located on both sides of the crushing box 9, and both are hollow shell structures with openings at the bottom. A horizontal plate 8 is welded and fixed to the lower end face of the first support shell 2 and the second support shell 3. The horizontal plate 8 is a horizontally arranged rectangular steel plate. The bottom of the crushing box 9 abuts against the upper end face of the horizontal plate 8. The horizontal plate 8 provides support for the crushing box 9. At the same time, the first support shell 2 and the second support shell 3 can limit the movement of the two sides of the crushing box 9 to prevent it from shifting during operation.

[0040] In this embodiment, the device also includes a liquid supply mechanism for providing flushing water to the flushing pipe 20. This liquid supply mechanism is driven by the power of the rotating shaft 11 inside the crushing chamber 9, eliminating the need for an additional power source, simplifying the device structure, and reducing energy consumption. Specifically, the liquid supply mechanism includes a circular plate 26, a piston cylinder 10, a movable piston 28, and a connecting rod 27. The circular plate 26 is fixed to one end of the rotating shaft 11 extending out of the crushing chamber 9 via a second one-way bearing, and the axis of the circular plate 26 coincides with the axis of the rotating shaft 11. The piston cylinder 10 is bolted to the inside of the second support shell 3. The piston cylinder 10 is a horizontally positioned cylindrical body, and the movable piston 28 is slidably connected inside it. A sealing ring is provided between the movable piston 28 and the inner wall of the piston cylinder 10 to ensure a tight seal. One end of the movable piston 28 extends to the outside of the piston cylinder 10 and is hinged to one end of the connecting rod 27 via a hinge shaft. The other end of the connecting rod 27 is hinged to the eccentric position of the circular plate 26 via a hinge shaft, forming a crank-slider mechanism. When the rotating shaft 11 rotates, it drives the circular plate 26 to rotate synchronously, and through the connecting rod 27, it pulls the moving piston 28 to make reciprocating linear motion in the piston cylinder 10.

[0041] A liquid inlet pipe 24 is installed on one side wall of the piston cylinder 10, and a liquid outlet pipe 22 is installed on the other side wall. A water storage tank 4 is fixed to the outer side wall of the second support shell 3 by bolts. The water storage tank 4 stores clean water. The other end of the liquid inlet pipe 24 is connected to the bottom outlet of the water storage tank 4, and the other end of the liquid outlet pipe 22 passes through the side walls of the second support shell 3 and the separation box 1 and is connected to the flushing pipe 20. To ensure unidirectional water flow, a liquid inlet check valve 25 is installed on the liquid inlet pipe 24. The liquid inlet check valve 25 is open from the water storage tank 4 to the piston cylinder 10, allowing only clean water in the water storage tank 4 to enter the piston cylinder 10 through the liquid inlet pipe 24. A liquid outlet check valve 23 is installed on the liquid outlet pipe 22. The liquid outlet check valve 23 is open from the piston cylinder 10 to the flushing pipe 20, allowing only clean water in the piston cylinder 10 to flow into the flushing pipe 20 through the liquid outlet pipe 22. When the moving piston 28 reciprocates inside the piston cylinder 10, a negative or positive pressure is formed inside the piston cylinder 10. With the cooperation of the inlet check valve 25 and the outlet check valve 23, the clean water in the water storage tank 4 is extracted and transported, so that the clean water is sprayed out through the nozzle 21 of the flushing pipe 20 to complete the flushing of the guide cylinder 14 and the spiral blade 30.

[0042] The working process of the device in this embodiment is as follows: Workers guide kitchen waste into the dumping pipe 7, where it falls into the rotating drum 33 and the guide tube 14 due to gravity. The motor 6 is started and controlled to rotate clockwise, driving the drive shaft 29, power shaft 35, and spiral blade 30 to rotate clockwise. Due to the friction between the spiral blade 30 and the guide tube 14, the guide tube 14 rotates, while the first one-way bearing is locked, keeping the guide tube 14 stationary. The rotating spiral blade 30 pushes the guide tube 14 towards its discharge end, simultaneously squeezing the waste and causing the liquid in the waste to permeate through the mesh wall of the guide tube 14 to the bottom of the separation box 1, eventually flowing to the drain pipe 5 and being discharged.

[0043] When the drive shaft 29 rotates, the rotating shaft 11 rotates under the transmission of the transmission wheel 19 and the transmission belt 18. The rotation of the rotating shaft 11 drives the second one-way bearing to rotate relative to the circular plate 26; that is, the circular plate 26 remains stationary.

[0044] As the spiral blade 30 rotates, the separated kitchen waste solids can be discharged through the guide tube 14 and finally fall into the guide pipe 13 and into the crushing box 9.

[0045] After the device has been running for a period of time, if the mesh wall of the guide tube 14 becomes slightly blocked, the motor 6 can be reversed to drive the drive shaft 29 and the power shaft 35 to rotate counterclockwise. At this time, the first one-way bearing is unlocked, and the rotating cylinder 33 rotates with the drive shaft 29, driving the guide tube 14 and the power shaft 35 to rotate counterclockwise synchronously through the connecting rod 34. When the guide tube 14 and the spiral blade 30 rotate synchronously, the relative motion between them disappears.

[0046] Meanwhile, the rotation of the rotating shaft 11 drives the second one-way bearing to rotate, which in turn drives the circular plate 26 to rotate. Under the transmission of the connecting rod 27, the moving piston 28 is driven to reciprocate within the piston cylinder 10, drawing clean water from the water storage tank 4 and transporting it to the flushing pipe 20. The clean water is sprayed out from the spray hole 21 to flush the inner wall of the guide cylinder 14 and the spiral blade 30, preventing solid waste from adhering and clogging the mesh. At this time, the guide cylinder 14 is in a rotating state, which makes the flushing effect of the guide cylinder 14 better.

[0047] Meanwhile, under the continuous flushing action of the flushing pipe 20, the garbage attached to the inner wall of the guide tube 14 and the spiral blade 30 is cleaned and removed. The removed garbage falls into the crushing box 9 through the guide tube 13 under the action of gravity. The solid garbage falling into the crushing box 9 is crushed into small particles by the crushing blade 12 driven by the rotating shaft 11. When the garbage in the crushing box 9 accumulates to a preset amount, the discharge door 15 is opened to discharge the crushed garbage for subsequent recycling.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
