Description

Technical Field

[0001] This application relates to the field of solid waste treatment, and in particular to a kitchen waste bin with wastewater separation capabilities. Background Technology

[0002] Food waste, also known as catering waste or food scraps, mainly comes from restaurants, canteens, and home kitchens. Food waste is characterized by high water content, rich organic matter, and easy decomposition and odor. Large-scale base station-type equipment is commonly used for food waste disposal. After the above process, it is sorted and stored as dry waste.

[0003] refer to Figure 1 Existing kitchen waste treatment facilities are usually workstations or large solid waste sites. Their common structure is a large metal cylinder 1, which provides sealing and support. The cylinder 1 contains a crushing unit 4 and a sewage separation unit 5, thereby realizing the collection and treatment of kitchen waste.

[0004] The drawback of existing technologies is that they usually require a long transportation and collection process before processing, during which kitchen waste is prone to rotting and emitting odors, affecting the subsequent cleaning process and polluting the air environment. Utility Model Content

[0005] To facilitate on-site separation of wastewater from kitchen waste, this application provides a kitchen waste bin with wastewater separation capabilities.

[0006] The technical solution for a kitchen waste bin with sewage separation capability provided in this application is as follows:

[0007] A food waste bin with sewage separation capability includes a cylindrical body for storing food waste, a lid hinged to the top of the cylindrical body, and, from top to bottom, a guide cone for sliding and guiding food waste, a crushing unit for crushing food waste, a sewage separation unit for filtering crushed food waste, a funnel for guiding filtered food waste, and a storage bin for containing food waste. A drain door is installed on the outer wall of the cylindrical body for pulling out the storage bin. After being collected, crushed, filtered, and compressed, the food waste enters the storage bin, which can be pulled out by opening the drain door.

[0008] By adopting the above technical solution, the cylinder is used to store kitchen waste. The top of the cylinder is hinged with a lid to achieve sealing of the inside of the cylinder. The guide cone installed on the top of the cylinder is used to guide the kitchen waste. The crushing group located at the bottom of the guide cone is a component for crushing kitchen waste. The sewage separation group is a component for filtering the crushed kitchen waste. The funnel guides the filtered kitchen waste so that the filtered kitchen waste can enter the storage bin. The storage bin, after storing dry waste, is discharged through the drain door.

[0009] Optionally, the crushing assembly includes a crushing fixing ring fixed to the inner wall of the cylinder, and a plurality of crushing teeth are rotatably mounted on the inner wall of the crushing fixing ring along the circumferential direction of the crushing fixing ring.

[0010] By adopting the above technical solution, the crushing unit includes a crushing fixing ring, which is fixed to the inner wall of the cylinder. The crushing fixing ring is provided with a number of crushing teeth, which are distributed along the circumference of the crushing fixing ring. The high-speed rotating crushing teeth crush the kitchen waste that is guided down through the guide cone bucket.

[0011] Optionally, the pulverizing teeth are arranged vertically, and the tips of several pulverizing teeth are used to pulverize kitchen waste. By adopting the above technical solution, a number of pulverizing teeth are used, and several pulverizing teeth are hinged vertically along the inner wall of the pulverizing fixing ring. The hinged pulverizing teeth can rotate, and the rotating pulverizing teeth can crush the input kitchen waste.

[0012] Optionally, the pulverizing assembly further includes distributing teeth for dispersing kitchen waste onto the pulverizing teeth, the distributing teeth being horizontally hinged to the middle of the pulverizing fixing ring.

[0013] By adopting the above technical solution, the rotating distributing teeth installed horizontally in the middle of the cylinder are used to distribute the kitchen waste that is thrown in downwards onto the crushing teeth by centrifugal force, so that the crushing teeth crush the kitchen waste.

[0014] Optionally, the wastewater separation unit includes a filter fixing ring fixedly connected to the inner wall of the cylinder, a sun gear ring slidably connected to the inner wall of the filter fixing ring, a planetary drive group provided on the outer side of the sun gear ring, the sun gear ring meshing with the planetary drive group, and a centrifugal conical group for separating kitchen waste wastewater fixedly connected to the inner wall of the sun gear ring.

[0015] By adopting the above technical solution, the outer wall of the filter fixing ring is fixed to the inner wall of the inner wall of the cylinder, providing a rotating mounting structure for the sun gear ring. The planetary drive group located on the outer side meshes with the sun gear ring, driving the sun gear ring and the centrifugal conical group fixed to the inner wall of the sun gear ring to rotate and centrifuge, thereby separating the wastewater from the solids in the kitchen waste. The wastewater in the kitchen waste includes organic matter, inorganic salts, and heavy metals, etc.; the solids in the kitchen waste include bones, crab shells, or fruit pits, etc.

[0016] Optionally, the centrifugal conical assembly includes a support mounting cone fixed to the sun gear ring, and a filter plate for separating kitchen waste and sewage is fixed to the inner side of the support mounting cone. The filter plate is conical and has several filter holes on its surface.

[0017] By adopting the above technical solution, the support cone is used to receive the kitchen waste pulverized by the pulverizing teeth. During its own rotation, solids in the kitchen waste, such as bones, crab shells, or fruit pits, remain on the inner wall of the filter plate. Wastewater in the kitchen waste, including organic matter, inorganic salts, and heavy metals, passes through the filter holes and is separated from the solids in the kitchen waste. The cone-shaped filter plate ensures that the solids in the kitchen waste always remain on the inner wall of the filter plate during the separation process and will not slide down to the bottom structure.

[0018] Optionally, the wastewater separation unit further includes a receiving tank ring for containing wastewater generated by centrifugation of the filter plate. A wastewater tank is provided on the outside of the receiving tank ring, and a wastewater connecting pipe is connected to one end of the receiving tank ring. The wastewater tank and the receiving tank ring are connected through the wastewater connecting pipe.

[0019] By adopting the above technical solution, the wastewater generated by centrifugal processing of the filter plate is contained in the containment ring, and the wastewater is connected to the wastewater tank through the wastewater connecting pipe, thereby playing the role of collecting and storing wastewater.

[0020] Optionally, the cross-section of the receiving groove ring is U-shaped, and the open end of the receiving groove ring faces the filter plate.

[0021] By adopting the above technical solution, the cross-section is U-shaped and the open end faces the filter plate, which can naturally collect the sewage generated by centrifugation from the filter plate.

[0022] Optionally, the bottom of the sewage separation unit is also equipped with a compression unit for compressing the kitchen waste after sewage separation. The compression unit includes two hinged doors on the inner wall of the cylinder for receiving the kitchen waste after sewage separation. The top of the two hinged doors is provided with two telescopic rod groups for compressing the kitchen waste after sewage separation. The two telescopic rod groups are arranged along the radial direction of the cylinder. The telescopic rod group includes a telescopic rod that provides compression movement. The ends of the telescopic rods are fixed with two pressure plates for compressing the kitchen waste after sewage separation.

[0023] By adopting the above technical solution, the compression unit is used to receive solids such as bones, crab shells, or fruit pits from kitchen waste filtered by the filter plate and compress them. The specific operation steps are as follows: two double-leaf doors receive solids such as bones, crab shells, or fruit pits from the kitchen waste filtered by the filter plate. Two pressure plates at the ends of two telescopic rods arranged radially move towards each other. These two moving pressure plates compress the solid kitchen waste scattered on the two double-leaf doors. The compressed solid kitchen waste falls into the bottom structure after the two double-leaf doors are opened. Optionally, the distance between the two pressure plates is L, the initial distance between the two pressure plates is L1, and the outlet diameter of the filter plate is A; then, L1>A; L1 / 2 <L<L1。

[0024] By adopting the above technical solution, the distance between the two pressure plates is greater than the outlet diameter of the filter plate, which allows the kitchen waste after sewage treatment to enter between the two pressure plates for easy compression. The stroke of the two telescopic rods is greater than L1 / 2, which prevents excessively compressed solid waste from splashing upwards when a large amount of waste is poured in.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The cylinder is used to store kitchen waste. The top of the cylinder is hinged with a lid to seal the inside of the cylinder. The guide cone installed on the top of the cylinder guides the kitchen waste. The crushing unit at the bottom of the guide cone is a component for crushing kitchen waste. The sewage separation unit is a component for filtering the crushed kitchen waste. The funnel guides the filtered kitchen waste so that it can enter the storage bin. The storage bin, after storing dry waste, is discharged through the drain door.

[0027] 2. The crushing unit includes a crushing fixing ring, which is fixed to the inner wall of the cylinder. The crushing fixing ring is provided with several crushing teeth, which are distributed along the circumference of the crushing fixing ring. The high-speed rotating crushing teeth crush the kitchen waste that is guided down through the guide cone bucket.

[0028] 3. A number of shredding teeth are connected vertically along the inner wall of the shredding ring. The shredding teeth can rotate after being connected, and the rotating shredding teeth can crush the put-in kitchen waste. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 2-7 This application will be described in further detail.

[0038] This application discloses a kitchen waste bin with sewage separation capability. (Refer to...) Figure 4 The kitchen waste bin with sewage separation capability includes a cylindrical body 1. The cylindrical body 1 primarily provides storage for waste and supports the internal structure. A hinged lid 2, connected to the cylindrical body 1, forms a sealed space with the cylindrical body 1, ensuring that the kitchen waste inside does not come into contact with outside air, thus preventing excessive oxidation-reduction reactions. Inside the cylindrical body 1, from top to bottom, are guide cones 3 for slidingly guiding the kitchen waste. A pulverizing group 4 is located at the bottom of the guide cone 3. The raw kitchen waste is guided by the guide cone 3 into the pulverizing group 4 for pulverization. 4. A sewage separation group 5 is provided at the bottom. The kitchen waste after crushing enters the sewage separation group 5 for centrifugal rotation to separate the sewage from the solid waste. A funnel 7 is provided at the bottom of the sewage separation group 5. The funnel 7 receives the solid waste after sewage separation and guides it downward. A storage bin 8 is provided at the bottom of the funnel 7. The solid waste after being guided by the funnel 7 enters the storage bin 8 for storage. The cylinder 1 is provided with a drain door 9. After the external operator opens the drain door 9, the storage bin 8 containing solid kitchen waste can be manually pulled out to complete the sewage separation in the kitchen waste.

[0039] refer to Figure 4 and Figure 5 The crushing unit 4 includes a crushing fixing ring 41, which is fixedly connected to the inner wall of the cylinder 1. Several crushing teeth 42 are hinged in the inner ring of the crushing fixing ring 41. The crushing teeth 42 are vertically and evenly arranged along the inner ring of the crushing fixing ring 41. The tips of the rotating crushing teeth 42 crush the falling kitchen waste.

[0040] refer to Figure 4 and Figure 5The crushing unit 4 also includes a material distribution tooth 43, which is horizontally installed in the middle of the fixed ring and rotatably connected to the middle of the crushing fixed ring 41. After the kitchen waste enters, it is rotated by the material distribution tooth 43 and then thrown onto the crushing tooth 42 by centrifugal force for crushing.

[0041] refer to Figure 6 The wastewater separation unit 5 includes a filter fixing ring 51, the outer wall of which is fixedly connected to the inner wall of the cylinder 1. A sun gear ring 52 is slidably connected to the inner wall of the filter fixing ring 51. A planetary drive group 53 is provided on the outer side of the sun gear ring 52. The planetary drive group 53 meshes with the sun gear ring 52 for transmission. A centrifugal conical group 54 is fixedly connected to the inner ring of the sun gear ring 52. The rotating sun gear ring 52 causes the centrifugal conical group 54 to separate the wastewater from the falling kitchen waste.

[0042] refer to Figure 6 The centrifugal conical assembly 54 includes a support mounting cone 541, which is fixed to the inner ring of the sun gear ring 52. A conical filter plate 542 is fixed to the inner side of the support mounting cone 541. The filter plate 542 is the main structure for separating dry and wet waste. Several filter holes 543 are evenly opened on the surface of the filter plate 542. The filtered wastewater is discharged through the filter holes 543 to other structures located at the bottom.

[0043] refer to Figure 4 The wastewater separation unit 5 also includes a receiving tank ring 55, which provides a structure for storing wastewater generated by centrifugation of the filter plate 542. A wastewater tank 56 is provided on one side of the receiving tank ring 55. The wastewater tank 56 is circular in shape. A wastewater connecting pipe 57 is provided between the wastewater tank 56 and the receiving tank ring 55. The wastewater collected in the receiving tank ring 55 enters the wastewater tank 56 for storage through the wastewater connecting pipe 57.

[0044] refer to Figure 4 The concave-shaped receiving groove ring 55 has its opening facing the filter plate 542 and is fixed to the inner wall of the cylinder 1, which can naturally collect the sewage obtained from the centrifugal rotation of the filter plate 542.

[0045] refer to Figure 7 At the bottom of the sewage separation unit 5, a compression unit 6 is also installed. The compression unit 6 includes two double doors 61, one end of which is hinged to the inner wall of the cylinder 1. The top of the two double doors 61 is provided with two telescopic rods 621 groups 62. The two telescopic rods 621 groups 62 arranged along the radial direction of the cylinder 1 are used to compress the filtered solid kitchen waste. The telescopic rods 621 groups 62 include telescopic rods 621 and pressure plates 622. The telescopic rods 621 provide the compression motion to the pressure plates 622, thereby compressing the solid kitchen waste falling to the top of the two double doors 61 and reducing the volume of the waste.

[0046] refer to Figure 7The opening and closing distance between the two pressure plates 622 is greater than the outlet size of the filter plate 542, i.e., L1>A, so that the solid kitchen waste after falling enters the top of the two double doors 61 and between the two pressure plates 622. The distance between the two pressure plates 622 is greater than half of the original distance between the two pressure plates 622, i.e., L1 / 2, so that the kitchen waste after sewage separation will not splash upward due to excessive compression.

[0047] The implementation principle of a kitchen waste bin with sewage separation capability according to an embodiment of this application is as follows: The operator opens the lid 2 and pours in the kitchen waste. The kitchen waste is thrown onto the rotating crushing teeth 42 by the centrifugal motion of the distributing teeth 43. The top of the crushing teeth 42 crushes the kitchen waste. The crushed kitchen waste is then spread onto the centrifugally rotating filter plate 542. Sewage passes through the filter holes 543 and enters the receiving tank ring 55. The sewage in the receiving tank ring 55 enters the sewage tank 56 through the sewage connecting pipe 57. After the solid kitchen waste is compressed by the pressure plate 622 driven by the telescopic rod 621, its volume decreases. The two double doors 61 open, and the compressed solid kitchen waste enters the storage bin 8. The operator opens the drain door 9 and pulls out the storage bin 8 containing the solid kitchen waste, thereby completing the separation of sewage from the overall kitchen waste.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
