Description

Technical Field

[0001] The present invention relates to the technical field of waste recycling, and in particular to a hotel kitchen waste crushing device and method thereof. Background Art

[0002] At present, garbage classification is being implemented in the whole country, but kitchen waste is one of the most difficult types of garbage to handle. Due to the characteristics of high water content, high salt content and high oil content, kitchen waste is not suitable for landfill or incineration. When people deal with kitchen waste, they need to crush the kitchen waste first, and then separate the liquid in the mixture after crushing. However, in the current kitchen waste treatment process, the material must be crushed first, and then the solid-liquid separation process is implemented. The existing process has the following problems, that is, when the crushed mixture is separated into dry and wet, the crushed kitchen waste must first be collected, and then squeezed through special dehydration equipment, resulting in the overall operation process being cumbersome and limited in efficiency.

[0003] To solve this problem, announcement number CN116371885A discloses an intelligent kitchen waste processing device, including a device box with an installation cavity provided inside, a crushing mechanism installed in the installation cavity, a conveying mechanism connected to the crushing mechanism, and an oil discharge mechanism installed on the conveying mechanism; the device box is provided with an inlet and an outlet, and one end of the inlet is connected to a conveying pipe; an oil outlet pipe is provided in the installation cavity, one end of the oil outlet pipe is connected to the first sleeve, and the other end of the oil outlet pipe is passed through and fixedly installed on the side wall of the device box.

[0004] However, during the use of the above-mentioned device, when the extrusion plate is used to crush and compress the kitchen waste, since the oil outlet is designed as an open structure, the oil contained in the kitchen waste tends to escape irregularly in multiple directions, which makes the separation efficiency of the kitchen waste low when separating the dry and wet parts, and also has an adverse effect on the subsequent recycling and processing process, significantly weakening the recycling and utilization effect of the kitchen waste. For this reason, we propose a kitchen waste crushing device and method for hotels. Summary of the Invention

DETAILED DESCRIPTION

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example 1: Please refer to Figures 1-11The present invention provides a technical solution: a hotel kitchen waste crushing device and method, including a crushing box 1, a crushing roller 2 and a crushing drive unit 4, and also includes a mounting plate 3, which is arranged in the crushing box 1, and a rotation groove 81 is opened in the mounting plate 3, and a through groove 82 is longitudinally opened on the mounting plate 3 to pass through the mounting plate 3 and the rotation groove 81.

[0047] The transfer tube 11 is rotatably disposed in the rotation groove 81 , and a feed groove 83 is provided on the transfer tube 11 for use in conjunction with the through groove 82 . The transfer tube 11 is provided with a plurality of liquid guide holes 101 .

[0048] The extrusion filter plate 12 and the extrusion filter plate 2 13 are fixedly arranged in the transfer tube 11, and the extrusion filter plate 2 13 is rotatably installed in the transfer tube 11, and the extrusion filter plate 2 13 is always seamlessly abutted with the extrusion filter plate 12. The liquid guide hole 101 is arranged between the extrusion filter plate 12 and the extrusion filter plate 2 13, and its position is located on the rear side of the extrusion filter plate 2 13 in the rotation direction during extrusion.

[0049] The synchronous driving unit 7 is disposed in the crushing box 1 and connected to the transfer pipe 11 and the second extrusion filter plate 13. It 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 guide 5 arranged in the crushing box 1, which guides the kitchen waste to the position of the crushing roller 2. The guide 5 is provided with a power member 6, which provides power for the crushing roller 2 to rotate.

[0051] The guide member 5 includes a material collecting bin 51 provided on the mounting plate 3 , a crushing bin 52 provided on the material collecting bin 51 , and the crushing bin 52 is connected to the material collecting bin 51 . A collecting bin 53 is provided in the crushing box 1 , and the collecting bin 53 is connected to the crushing bin 52 .

[0052] The power part 6 includes a plurality of rotating shafts 61 rotatably arranged in the crushing bin 52, and one end of the rotating shaft 61 passes through the crushing bin 52, and the plurality of rotating shafts 61 are provided with mutually meshing crushing gears 62, and a crushing motor 63 is provided in 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, and the rotation of the rotating shaft 61 drives the crushing gear 62 to rotate, thereby driving the mutually meshing multiple crushing gears 62 to rotate synchronously, and then drives the two crushing rollers 2 on the rotating shaft 61 to rotate in opposite directions. By driving the crushing rollers 2 to rotate in opposite directions through the crushing gears 62 and the rotating shaft 61, the kitchen waste is grabbed and torn, so that the garbage is crushed into smaller pieces, and the fine kitchen waste can be conveniently squeezed and dehydrated subsequently. At the same time, the gear meshing design of the crushing gear 62 ensures the synchronous operation of the two rollers, reduces the risk of jamming, and thus improves the crushing efficiency.

[0053] The synchronous drive unit 7 includes a separator 8 arranged in the mounting plate 3 to ensure that the extrusion filter plate 2 13 always fits the wall of the transfer tube 12 during the rotation process. A driving member 9 is provided in the mounting plate 3, and the driving member 9 is used to drive the transfer tube 11 to rotate, and at the same time, the extrusion filter plate 2 13 is driven to rotate to squeeze the kitchen waste in the transfer tube 11. An oil drain member 10 is provided on the mounting plate 3, and the oil drain member 10 is used to discharge the squeezed oil and water out of the transfer tube 11.

[0054] The separator 8 includes a buffer groove 84 provided on the extrusion filter plate 1 12 and the extrusion filter plate 2 13 , a buffer plate 86 is slidably provided in the buffer groove 84 , a buffer spring 85 is provided on the buffer plate 86 , and 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 extrusion filter plate 2 13 always fits the wall of the transfer tube 11 during the rotation process. By ensuring that the extrusion filter plate 2 13 always fits the transfer tube 11, the following effects and benefits are achieved. The close fit between the extrusion filter plate 2 13 and the wall of the transfer tube 11 effectively prevents the leakage of kitchen waste, ensures the sealing of the extrusion process, thereby improving the treatment effect and hygiene standards. The good sealing enables the extrusion filter plate 2 13 to more effectively squeeze the kitchen waste during rotation, thereby 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 extrusion filter plate 2 13 during the rotation process, and enhances the stability and reliability of the entire extrusion process, which helps to reduce the risk of equipment failure and damage and improve the durability and service life of the equipment.

[0056] A telescopic rod 87 is provided on the extrusion filter plate 12 and the extrusion filter plate 2 13, and a positioning plate 88 is provided on the telescopic rod 87. An extrusion spring 89 is provided on the telescopic rod 87, and a cleaning brush 810 is provided on the positioning plate 88 for use with the filtrate holes on the extrusion filter plate 12 and the extrusion filter plate 2 13. A plurality of magnets 811 are provided on the opposite side of the positioning plates 88, and the two magnets 811 are opposite to each other with the same poles. When the extrusion filter plate 2 13 retracts and fits into the extrusion filter plate 1 12, the two magnets 811 with the same poles opposite to each other generate a mutually repulsive force. Under the push of this repulsive force, the positioning plate 88 overcomes the elastic force of the extrusion spring 89 and moves backward, thereby driving the cleaning brush 810 on the positioning plate 88 to dock with the extrusion filter plate 12 and the extrusion filter plate 2 The filtrate holes on the filter plate 2 13 are then effectively cleaned by the cleaning brush 810 to prevent residue accumulation and clogging. This design brings significant effects and benefits. By regularly cleaning the filtrate holes, long-term accumulation and corrosion of residues are avoided, thereby significantly extending the service life of the filtrate holes and related components, and reducing the replacement costs caused by component damage. The automatic cleaning function of the filtrate holes reduces the need for manual intervention, reduces the maintenance frequency and cost of the equipment, and at the same time, due to the reduction in equipment failure rate, it also reduces downtime caused by maintenance, and improves the overall operating efficiency of the equipment. Not only that, the filtrate holes after cleaning can remain unobstructed, ensuring that the oil and water in the kitchen waste can be filtered out smoothly, thereby improving the filtration efficiency and separation effect.

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

[0058] A rotating shaft 97 is provided for rotation in the transfer tube 11, and the rotating shaft 97 passes through the extrusion filter plate 2 13 and is connected to the extrusion filter plate 2 13. One end of the rotating shaft 97 passes through the transfer tube 11, and a transmission shaft 98 is provided on the transfer tube 11. A driving pulley 99 is provided on both the rotating shaft 97 and the transmission shaft 98, and a driving belt 910 is provided on the driving pulley 99. An extrusion gear 911 is provided on the transmission shaft 98. A plurality of connecting plates 912 are provided on the side walls of the rotating groove 81, and an arc plate 1 913 and an arc plate 2 914 are provided on the connecting plates 912 respectively. The outer surface of the arc plate 1 913 The inner ring of the ring and the arc plate 2 914 are both provided with a tooth groove 915 that meshes with the extrusion gear 911. When the drive motor 916 is working, it drives the synchronous worm 96 to rotate, and 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 drive shaft 92 connected thereto to rotate, and the rotation of the drive shaft 92 drives the drive gear 93 to rotate. The rotation of the drive gear 93 drives the drive ring gear 94 meshed with it to rotate synchronously. The rotation of the drive ring gear 94 drives the transfer tube 11 to rotate. The rotation of the transfer tube 11 drives the transmission shaft 98 provided thereon to rotate. The rotation of the transmission shaft 98 drives the extrusion gear 911 and the tooth groove 91 5 engages, thereby driving the transmission shaft 98 to rotate, the rotation of the transmission shaft 98 drives the driving pulley 99 to rotate, the rotation of the driving pulley 99 drives the driving belt 910 to rotate, and then the driving belt 910 drives the rotating shaft 97 to rotate synchronously, and the rotation of the rotating shaft 97 drives the squeezing filter plate 2 13 to rotate to squeeze the kitchen waste in the transfer pipe 11. At the same time, due to the rotation of the transfer pipe 11, the feed trough 83 is separated from the through groove 82 on the top surface of the mounting plate 3, so that a sealed environment is formed in the transfer pipe 11. The transfer pipe 11 remains sealed during squeezing, preventing leakage of oil and water and external pollution, and further improving the squeezing effect and oil-water separation efficiency. At the same time, the squeezing effect of the kitchen waste in the transfer pipe 11 is improved. Under the squeezing of the squeezing filter plate 12 and the squeezing filter plate 2 13, the liquid in the kitchen waste flows out through the filtrate hole. The rotation of the squeezing filter plate 12 causes the kitchen waste to be subjected to squeezing force in the closed transfer pipe 11, thereby squeezing out the oil and water in the waste. The outflowing liquid passes through the liquid guide hole 101 and the liquid collecting hole 102 in turn, and finally enters the connecting pipe 104 through the oil discharge pipe 103, and then enters the liquid storage tank 105 through the connecting pipe 104, and finally is discharged through the liquid storage tank 105, thereby 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 tube 11, the feed groove 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 arc plate 2 914, thereby driving the transmission shaft 98 and the rotating shaft 97 to rotate in the opposite direction, causing the arc plate 2 914 to rotate in the opposite direction, loosening the squeezed kitchen waste, thereby facilitating the discharge of the kitchen waste from the through groove 82. After the extrusion is completed, the processed kitchen waste can be automatically discharged from the opening on the other side. This design avoids the re-contact and mixing of the processed garbage and the unprocessed garbage, reduces the risk of secondary pollution, and at the same time improves the efficiency and effect of subsequent treatment, and improves the separation efficiency of oil, water and solids.

[0060] The oil drain member 10 includes a liquid collecting hole 102 provided on the transfer pipe 11 and connected to the liquid guide hole 101. An oil drain pipe 103 rotatably connected to the transfer pipe 11 is provided in the rotating groove 81. The oil drain pipe 103 is connected to the liquid collecting hole 102. A connecting pipe 104 is provided on the oil drain pipe 103. A liquid storage tank 105 is provided in the crushing box 1. The liquid storage tank 105 is connected to the connecting pipe 104. The outflowing liquid passes through the liquid guide hole 101, the liquid collecting hole 102 and the oil drain pipe 103 and smoothly flows into the connecting pipe 104. Then, it is diverted to the liquid storage tank 105 through the connecting pipe 104. Finally, the liquid is discharged from the liquid storage tank 105. This process realizes the solid-liquid separation and classified collection of kitchen waste, reducing the manual operation links.

[0061] The crushing method is as follows:

[0062] S1. Crushing

[0063] The food waste is transported to the crushing roller 2 through the guide 5. The crushing motor 63 drives the rotating shaft 61 to drive the mutually engaged crushing gears 62, so that the two rollers rotate in opposite directions to crush the food waste.

[0064] S2. Material transfer

[0065] The crushed kitchen waste enters the collection bin 53 and then enters the transfer pipe 11 through the feed trough 83 and the through slot 82;

[0066] S3, extrusion separation

[0067] The transfer pipe 11 is driven by the driving member 9 to rotate the second filter plate 13 relative to the first filter plate 12, thereby squeezing the kitchen waste and separating the oil and water in the kitchen waste;

[0068] S4, oil-water separation

[0069] During the extrusion process, the liquid components are discharged from the filtrate holes and collected through the liquid guide hole 101 → the liquid collection hole 102 → the oil discharge pipe 103 → the liquid storage tank 105. When the second extrusion filter plate 13 is reset, the repulsive force between the magnets 811 drives the cleaning brush 810 to move, thereby cleaning the filtrate holes on the first extrusion filter plate 12 and the second extrusion filter plate 13 to prevent the holes from being blocked.

[0070] S5. Solid discharge

[0071] After the extrusion is completed, the feed 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] Example 2: Please refer to Figure 12 The present invention provides a technical solution: a discharge bin 14 is provided in the crushing box 1, and the discharge bin 14 is communicated with the through slot 82. A discharge pipe 15 is provided in the crushing box 1, and the discharge pipe 15 is communicated with the discharge bin 14. A discharge auger 16 is rotatably provided in the discharge pipe 15. One end of the discharge pipe 15 passes through the crushing box 1, and the kitchen waste falling from the through slot 82 first enters the discharge bin 14, and then enters the discharge pipe 15 through the discharge bin 14, and is discharged from the crushing box 1 under the drive of 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 under the drive of the discharge auger 16 in the discharge pipe 15, thereby realizing the discharge of 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.
