Description

Technical Field

[0001] The present invention relates to the technical field of garbage recycling, and particularly to a kitchen waste crushing device and method for hotels. Background Art

[0002] At present, garbage classification is being gradually promoted across the country. However, kitchen waste is one of the more difficult types of garbage to handle. Due to the characteristics of high water content, high salt content, and high oil content in kitchen waste, it is not suitable for landfill or incineration. When people process kitchen waste, they need to first crush the kitchen waste and then separate the liquid in the mixture. However, in the current stage of kitchen waste treatment, the material needs to be crushed first, and then the solid-liquid separation process is implemented. The existing process has the following problems: when the crushed mixture is subjected to dry-wet separation, the crushed kitchen waste needs to be collected first, and then the pressing treatment is carried out through a special dehydration device, resulting in a cumbersome overall operation process and limited efficiency.

[0003] To solve this problem, the patent with publication number CN116371885A discloses an intelligent kitchen waste treatment device, which includes a device box body with an installation cavity formed inside, a crushing mechanism installed in the installation cavity, a conveying mechanism communicated with the crushing mechanism, and an oil drainage mechanism installed on the conveying mechanism; a feeding port and a discharging port are formed on the device box body, and one end of the feeding port is communicated with a conveying pipe; an oil outlet pipe is arranged in the installation cavity, one end of the oil outlet pipe is communicated with the first sleeve, and the other end of the oil outlet pipe passes through and is fixedly installed on the side wall of the device box body.

[0004] However, during the process of using the above device to crush and compress kitchen waste by using the pressing plate, since the oil outlet holes are designed as an open structure, the oil contained in the kitchen waste often escapes in multiple directions irregularly. This makes the separation efficiency of the kitchen waste during dry-wet separation relatively low, and also has an adverse impact on the subsequent recycling process, significantly weakening the recycling effect of the kitchen waste. Therefore, we propose a kitchen waste crushing device and method for hotels. Summary of the Invention

[0031] 1. By driving the first extrusion filter plate to rotate, the crushed kitchen waste entering the transfer pipe is extruded. During this process, the oil and water in the kitchen waste are fully squeezed out. At the same time, the transfer pipe remains sealed during extrusion. By keeping the transfer pipe sealed, the extrusion effect on the kitchen waste in the transfer pipe is improved. After the extrusion is completed, the processed kitchen waste can be automatically discharged from the other opening, avoiding re-contact with the unprocessed kitchen waste mixture, thereby improving the separation efficiency of oil and water and solids, reducing the time consumed for separating wet and dry kitchen waste, and improving the separation efficiency of wet and dry kitchen waste.

Specific embodiments

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] Embodiment 1: Please refer to Figures 1 - 11, the present invention provides a technical solution: a kitchen waste crushing device and method for hotels, including a crushing box 1, a crushing roller 2 and a crushing drive unit 4, and further including a mounting plate 3 disposed inside the crushing box 1. A rotating groove 81 is formed in the mounting plate 3, and a through groove 82 penetrating the mounting plate 3 and the rotating groove 81 is longitudinally formed on the mounting plate 3.

[0047] A transfer pipe 11 is rotatably disposed inside the mounting plate 3, and a feeding groove 83 cooperating with the through groove 82 is formed on the transfer pipe 11. A plurality of liquid guiding holes 101 are formed in the transfer pipe 11.

[0048] A first extrusion filter plate 12 and a second extrusion filter plate 13. The first extrusion filter plate 12 is fixedly disposed inside the transfer pipe 11, and the second extrusion filter plate 13 is rotatably mounted inside the transfer pipe 11, and the second extrusion filter plate 13 is always in seamless contact with the first extrusion filter plate 12. The liquid guiding holes 101 are disposed between the first extrusion filter plate 12 and the second extrusion filter plate 13, and are located on the rear side in the rotation direction of the second extrusion filter plate 13.

[0049] A synchronous drive unit 7 is disposed inside the crushing box 1 and is connected to the second extrusion filter plate 13 of the transfer pipe 11, and is used to drive the transfer pipe 11 to rotate and synchronously drive the second extrusion filter plate 13 to rotate during the rotation process.

[0050] The crushing drive unit 4 includes a guiding member 5 disposed inside the crushing box 1, and the kitchen waste is guided to the position of the crushing roller 2 by the guiding member 5. A power member 6 is disposed on the guiding member 5, and the power member 6 provides power for the rotation of the crushing roller 2.

[0051] The guiding member 5 includes an aggregate bin 51 disposed on the mounting plate 3. A crushing bin 52 is disposed on the aggregate bin 51. The crushing bin 52 is communicated with the aggregate bin 51. A collection bin 53 is disposed inside the crushing box 1, and the collection bin 53 is communicated with the crushing bin 52.

[0052] The power member 6 includes a plurality of rotating shafts 61 rotatably disposed inside the crushing bin 52, and one end of the rotating shaft 61 penetrates the crushing bin 52. A plurality of mutually meshing crushing gears 62 are disposed on the plurality of rotating shafts 61. A crushing motor 63 is disposed inside the crushing box 1, and the power output end of the crushing motor 63 is connected to the rotating shaft 61. After the crushing motor 63 works, it drives the rotating shaft 61 to rotate. The rotation of the rotating shaft 61 drives the crushing gears 62 to rotate, thereby driving a plurality of mutually meshing crushing gears 62 to rotate synchronously, and further driving the two crushing rollers 2 on the rotating shaft 61 to rotate towards each other. By the crushing gears 62 and the rotating shaft 61 driving the crushing rollers 2 to rotate towards each other, the kitchen waste is grabbed and torn, so that the waste is crushed more finely. The fine kitchen waste can be conveniently squeezed and dehydrated later. At the same time, the gear meshing design of the crushing gears 62 ensures the synchronous operation of the double rollers, reduces the risk of jamming, and thus improves the crushing efficiency.

[0053] The synchronous drive unit 7 includes a separating member 8 disposed within the mounting plate 3. The separating member 8 is used to separate oil and water from the broken kitchen waste. A driving member 9 is provided on the separating member 8. The driving member 9 is used to drive the transfer pipe 11 to rotate and, while rotating, drive the second extrusion filter plate 13 to rotate to extrude the kitchen waste within the transfer pipe 11. A drain member 10 is provided on the mounting plate 3. The drain member 10 is used to drain the extruded oil and water out of the transfer pipe 11.

[0054] The separating member 8 includes buffer grooves 84 provided on the first extrusion filter plate 12 and the second extrusion filter plate 13. A buffer plate 86 is slidably disposed within the buffer grooves 84. A buffer spring 85 is provided on the buffer plate 86. One end of the buffer spring 85 is connected to the buffer groove 84.

[0055] The design of the buffer plate 86 and the buffer spring 85 ensures that the second extrusion filter plate 13 always fits against the inner wall of the transfer pipe 11 during rotation. The fact that the second extrusion filter plate 13 always fits against the transfer pipe 11 brings the following effects and benefits. The tight fit between the second extrusion filter plate 13 and the inner wall of the transfer pipe 11 effectively prevents the leakage of kitchen waste, ensuring the sealing performance during the extrusion process, thereby improving the treatment effect and hygiene standards. The good sealing performance enables the second extrusion filter plate 13 to more effectively extrude the kitchen waste when rotating, improving the waste treatment efficiency. At the same time, the design of the buffer plate 86 and the buffer spring 85 reduces the vibration and impact of the second extrusion filter plate 13 during rotation, enhancing the stability and reliability of the entire extrusion process. This helps to reduce the risk of equipment failure and damage, and improves the durability and service life of the equipment.

[0056] A telescopic rod 87 is provided on the first extrusion filter plate 12 and the second extrusion filter plate 13. A positioning plate 88 is provided on the telescopic rod 87. A compression spring 89 is sleeved on the telescopic rod 87. A cleaning brush 810 that cooperates with the filtrate holes on the first extrusion filter plate 12 and the second extrusion filter plate 13 is provided on the positioning plate 88. Magnets 811 are provided on the opposite sides of multiple positioning plates 88, and the two magnets 811 have the same poles facing each other. When the second extrusion filter plate 13 retracts and fits with the first extrusion filter plate 12, the two magnets 811 with the same poles facing each other generate a repulsive force. Driven by this repulsive force, the positioning plate 88 moves backward against the elastic force of the compression spring 89, thereby driving the cleaning brush 810 on the positioning plate 88 to dock with the filtrate holes on the first extrusion filter plate 12 and the second extrusion filter plate 13. The cleaning brush 810 immediately effectively cleans the filtrate holes, preventing residue accumulation and blockage. This design brings significant effects and benefits. By regularly cleaning the filtrate holes, the long-term accumulation and corrosion of residues are avoided, thereby significantly extending the service life of the filtrate holes and related components, reducing the replacement cost caused by component damage. The automatic cleaning function of the filtrate holes reduces the need for manual intervention, lowers the maintenance frequency and cost of the equipment. At the same time, due to the reduction of equipment failure rate, the downtime caused by maintenance is also reduced, improving the overall operating efficiency of the equipment. Moreover, the cleaned filtrate holes can remain unobstructed, ensuring that the oil and water in the kitchen waste can be smoothly filtered out, improving the filtration efficiency and separation effect.

[0057] The driving member 9 includes a plurality of driving chambers 91 opened on the mounting plate 3. A driving shaft 92 is rotatably provided on the upper side wall of the driving chamber 91. One end of the driving shaft 92 extends into the rotating groove 81. A driving gear 93 is provided at one end of the driving shaft 92 located in the rotating groove 81. A driving gear ring 94 that meshes with the driving gear 93 is provided on the transfer pipe 11. A synchronous worm gear 95 is provided at one end of the driving shaft 92 located in the driving chamber 91. A synchronous worm 96 that meshes with the synchronous worm gear 95 is rotatably provided on the mounting plate 3. The synchronous worm 96 penetrates through a plurality of driving chambers 91. A driving motor 916 is provided on the mounting plate 3. The power output end of the driving motor 916 is connected to the synchronous worm 96.

[0058] A rotating shaft 97 is rotatably arranged in the transfer pipe 11. The rotating shaft 97 penetrates through the second extrusion filter plate 13 and is connected to the second extrusion filter plate 13. One end of the rotating shaft 97 penetrates through the transfer pipe 11. A transmission shaft 98 is arranged on the transfer pipe 11. Driving belt pulleys 99 are arranged on both the rotating shaft 97 and the transmission shaft 98. A driving belt 910 is arranged on the driving belt pulleys 99. An extrusion gear 911 is arranged on the transmission shaft 98. A plurality of connecting plates 912 are arranged on the side wall of the rotating groove 81. An arc plate one 913 and an arc plate two 914 are respectively arranged on the connecting plates 912. Tooth grooves 915 engaged with the extrusion gear 911 are formed in the outer ring of the arc plate one 913 and the inner ring of the arc plate two 914. When the driving motor 916 works, it drives the synchronous worm 96 to rotate. The rotation of the synchronous worm 96 drives the synchronous worm wheel 95 to rotate. The rotation of the synchronous worm wheel 95 drives the driving shaft 92 connected thereto to rotate. The rotation of the driving shaft 92 drives the driving gear 93 to rotate. The rotation of the driving gear 93 drives the driving gear ring 94 engaged therewith to rotate synchronously. The rotation of the driving gear ring 94 drives the transfer pipe 11 to rotate. While the transfer pipe 11 rotates, it drives the transmission shaft 98 arranged thereon to rotate. The rotation of the transmission shaft 98 drives the extrusion gear 911 to engage with the tooth groove 915, thereby driving the transmission shaft 98 to rotate. The rotation of the transmission shaft 98 drives the driving belt pulley 99 to rotate. The rotation of the driving belt pulley 99 drives the driving belt 910 to rotate. Furthermore, the rotation shaft 97 is driven to rotate synchronously through the driving belt 910. The rotation of the rotation shaft 97 drives the second extrusion filter plate 13 to rotate to extrude the kitchen waste in the transfer pipe 11. At the same time, since the rotation of the transfer pipe 11 causes the feed slot 83 to be separated from the through slot 82 on the top surface of the mounting plate 3, a sealed environment is formed in the transfer pipe 11. The transfer pipe 11 maintains a sealed state during extrusion, preventing the leakage of oil and water and external pollution, further improving the extrusion effect and the oil-water separation efficiency. At the same time, the extrusion effect of the kitchen waste in the transfer pipe 11 is improved. Under the extrusion of the first extrusion filter plate 12 and the second extrusion filter plate 13, the liquid in the kitchen waste flows out through the filtrate holes. The rotation of the first extrusion filter plate 12 causes the kitchen waste to be subjected to extrusion force in the sealed transfer pipe 11, thereby squeezing out the oil and water in the waste. The flowing liquid sequentially passes through the liquid guide holes 101 and the liquid collecting holes 102, and finally enters the connecting pipe 104 through the oil discharge pipe 103, then enters the liquid storage bin 105 through the connecting pipe 104, and finally is discharged through the liquid storage bin 105, realizing solid-liquid separation and classified collection, reducing manual intervention and alleviating the work pressure of the staff.

[0059] During the continuous rotation of the transfer pipe 11, the feeding trough 83 gradually docks with the through groove 82 on the bottom surface of the mounting plate 3. At this time, the extrusion gear 911 engages with the tooth groove 915 on the second arc-shaped plate 914, thereby driving the transmission shaft 98 and the rotating shaft 97 to rotate in the reverse direction, causing the second arc-shaped plate 914 to rotate in the reverse direction and loosen the extruded food waste, facilitating the discharge of the food waste from the through groove 82. After the extrusion is completed, the processed food waste can automatically discharge from the other opening. This design avoids the re-contact and mixing of the processed waste and the unprocessed waste, reduces the risk of secondary pollution, and improves the efficiency and effect of subsequent processing, as well as the separation efficiency of oil-water and solids.

[0060] The oil discharge member 10 includes a liquid collection hole 102 opened on the transfer pipe 11 and communicated with the liquid guide hole 101. A drain pipe 103 rotatably connected to the transfer pipe 11 is arranged in the rotation groove 81. The drain pipe 103 is communicated with the liquid collection hole 102. A connecting pipe 104 is arranged on the drain pipe 103. A liquid storage bin 105 is arranged in the crushing box 1. The liquid storage bin 105 is communicated with the connecting pipe 104. The flowing-out liquid smoothly converges into the connecting pipe 104 through the liquid guide hole 101, the liquid collection hole 102 and the drain pipe 103, and then is guided to the liquid storage bin 105 through the connecting pipe 104. Finally, the liquid discharges from the liquid storage bin 105. This process realizes the solid-liquid separation and classified collection of food waste, reducing the manual operation links.

[0061] The crushing method is as follows:

[0062] S1. Crushing treatment

[0063] The food waste is conveyed to the crushing roller 2 through the guiding member 5. The crushing motor 63 drives the rotating shaft 61 to drive the mutually engaged crushing gears 62 to realize the opposite rotation and crushing of the double rollers.

[0064] S2. Material transfer

[0065] The crushed food waste enters the collection bin 53 and then enters the transfer pipe 11 through the cooperation of the feeding trough 83 and the through groove 82.

[0066] S3. Extrusion separation

[0067] The driving member 9 is used to drive the separating member 8 to work, so that the second extrusion filter plate 13 rotates relative to the first extrusion filter plate 12, thereby extruding the food waste and separating the oil and water in the food waste.

[0068] S4. Oil-water separation

[0069] During the extrusion process, the filtrate holes discharge the liquid components, and the oil and water are collected through the liquid guide hole 101 → the liquid collecting hole 102 → the oil discharge pipe 103 → the liquid storage bin 105. When the extrusion filter plate two 13 is reset, the cleaning brush 810 is driven to move by the repulsive force between the magnets 811, so as to clean the filtrate holes on the extrusion filter plate one 12 and the extrusion filter plate two 13 to prevent the holes from being blocked.

[0070] S5. Solid discharge

[0071] After the extrusion is completed, the feeding groove 83 on the transfer pipe 11 is docked with the through groove 82 on the bottom surface of the mounting plate 3, so that the dehydrated solids in the transfer pipe 11 are discharged from the transfer pipe 11 through the through groove 82.

[0072] Embodiment 2: Please refer to Figure 12 , the present invention provides a technical solution: a discharge bin 14 is arranged in the crushing box 1, the discharge bin 14 is communicated with the through groove 82, a discharge pipe 15 is arranged in the crushing box 1, the discharge pipe 15 is communicated with the discharge bin 14, a discharge auger 16 is rotatably arranged in the discharge pipe 15, one end of the discharge pipe 15 penetrates through the crushing box 1, the kitchen waste falling from the through groove 82 first enters the discharge bin 14, then enters the discharge pipe 15 through the discharge bin 14, and is discharged from the crushing box 1 driven by the auger in the discharge pipe 15. The discharge bin 14 is communicated with the discharge pipe 15, and the kitchen waste is discharged from the crushing box 1 driven by the discharge auger 16 in the discharge pipe 15, realizing the discharge of the kitchen waste. At the same time, the automatic design of the discharge auger 16 reduces the frequency and difficulty of manual cleaning of the crushing box 1, so that the staff does not need to frequently open the crushing box 1 for cleaning.
