Description

Technical Field

[0001] This utility model belongs to the technical field of waste sorting cabinets, specifically relating to an environmentally friendly waste sorting cabinet. Background Technology

[0002] With increasing environmental awareness, waste sorting has become a crucial aspect of sustainable development in modern society. Currently, common waste sorting methods mainly rely on manual sorting or simple recycling bins. In scenarios involving manual sorting, such as waste treatment plants, large quantities of waste need to be manually sorted, which is not only inefficient but also exposes sorting workers to harsh waste environments for extended periods, posing significant health risks. Simple recycling bins typically only have external labels indicating categories such as recyclables, hazardous waste, kitchen waste, and other waste. However, in practice, residents often misjudge the types of waste, leading to severe mixed waste disposal.

[0003] Authorized publication number "CN219729241U" describes a waste sorting cabinet, relating to the technical field of waste sorting cabinets. It includes a base, a recyclable waste cabinet, a kitchen waste cabinet, a central service counter, a hazardous waste cabinet, a other waste cabinet, and a rear waste sorting chamber. The central service counter is located in the center of the upper surface of the base, the recyclable waste cabinet and the kitchen waste cabinet are located on the left side of the upper surface of the base, and the hazardous waste cabinet and the other waste cabinet are located on the right side of the upper surface of the base. Multiple sets of support legs are provided on the lower surface of the base, and the rear waste sorting chamber is located at the rear end of the base, with a top plate on top of the rear waste sorting chamber. This utility model facilitates waste sorting and storage, and can automatically spray disinfection. It can also ventilate and dry the interiors of different waste sorting cabinets to prevent excessive moisture, which can easily breed bacteria and cause odors, thus helping to keep the cabinets dry and hygienic, making them safer and more hygienic to use.

This helps keep the bins dry and hygienic, making them safer and more hygienic to use. However, the aforementioned patent has certain limitations in its use. The equipment cannot separate liquid and solid impurities in a unified manner. Instead, it processes them separately in different areas: the liquid area is responsible for separating impurities from waste liquids, while the solid area crushes solid waste. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly waste sorting bin, which aims to solve the problem that existing equipment cannot uniformly separate liquid and solid impurities, but instead processes them separately through different areas: the liquid area is responsible for separating impurities from waste liquids, while the solid area is responsible for crushing solid waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly waste sorting bin includes:

[0008] The sorting cabinet body has a sewage discharge trough and a drainage trough on its outer surface. A temperature sensor is fixedly connected to one side of the sorting cabinet body. Screws are rotatably connected to the inner walls of the sewage discharge trough and the drainage trough. A motor is fixedly connected to one side of the sorting cabinet body. Connecting grooves are fixedly connected to the inner walls of both sides of the drainage trough. A second connecting plate is fixedly connected inside the sorting cabinet body. A discharge port is fixedly connected to one side of the second connecting plate. The height of the discharge port is the same as that of the connecting groove. Two crushing sleeves are rotatably connected to the inner walls of both sides of the sewage discharge trough, and the two crushing sleeves mesh with each other. Secondary filter screens are fixedly connected to the inner walls of both sides of the second connecting plate.

[0009] A cleaning mechanism is located inside the sorting cabinet and is used to push the waste contained in the liquid on the upper side of the connecting groove.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. In this solution, by setting up sewage discharge troughs and drainage troughs, and in conjunction with screws, crushing sleeves, connecting troughs and other structures, the different types of waste can be classified and pre-processed.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figures 1-4 The present invention provides the following technical solution:

[0035] An environmentally friendly waste sorting bin includes:

[0036] The sorting cabinet body 1 has a sewage discharge trough 5 and a drainage trough 3 on its outer surface. A temperature sensor 6 is fixedly connected to one side of the sorting cabinet body 1. A lead screw 19 is rotatably connected to the inner walls of the sewage discharge trough 5 and the drainage trough 3. A motor 2 is fixedly connected to one side of the sorting cabinet body 1. Connecting grooves 9 are fixedly connected to the inner walls of both sides of the drainage trough 3. A second connecting plate 13 is fixedly connected inside the sorting cabinet body 1. A discharge port 15 is fixedly connected to one side of the second connecting plate 13. The height of the discharge port 15 is the same as that of the connecting groove 9. Two crushing sleeves 16 are rotatably connected to the inner walls of both sides of the sewage discharge trough 5. The two crushing sleeves 16 mesh with each other. A secondary filter screen 14 is fixedly connected to the inner walls of both sides of the second connecting plate 13.

[0037] The cleaning mechanism is located inside the sorting cabinet body 1. The cleaning mechanism is used to push the garbage contained in the liquid on the upper side of the connecting groove 9.

[0038] In a specific embodiment of this utility model, the function of the sewage tank 5 is to collect and preliminarily treat liquid waste containing a large amount of solid impurities or pollutants. Two crushing sleeves 16 are interlocked and installed on the inner wall of the sewage tank 5 to crush the solid waste in the sewage tank 5, breaking large pieces of solid waste into smaller pieces, which facilitates subsequent processing and improves waste treatment efficiency.

[0039] The drainage trough 3 is mainly used to treat relatively clear liquid waste, or to further drain liquids that have undergone preliminary treatment. The connecting trough 9 is fixed to the inner walls on both sides of the drainage trough 3, providing support and guidance for the transport and treatment of waste in the liquid. The drainage trough 3 is separate from the sewage trough 5, which helps to achieve the classified treatment of different types of liquid waste and improves the treatment efficiency.

[0040] Temperature sensor 6 is fixed to one side of the sorting cabinet body 1 and can monitor the temperature inside or around the sorting cabinet body 1 in real time. By sensing temperature changes, it can promptly detect any abnormalities that may occur during the waste treatment process, such as the high temperature generated by waste fermentation, so that corresponding measures can be taken to ensure the safe and stable operation of the equipment. At the same time, it can also optimize the waste treatment process based on temperature conditions.

[0041] Motor 2 is installed on one side of the sorting cabinet body 1, serving as a power source to provide power for the rotation of components such as lead screw 19 and crushing sleeve 16. Motor 2 drives lead screw 19 to rotate, enabling functions such as conveying and stirring of waste in sewage tank 5; it drives crushing sleeve 16 to rotate, realizing the crushing operation of solid waste, ensuring that the entire waste treatment process can operate automatically and efficiently.

[0042] In addition to providing support and guidance for waste conveying within the drainage trough 3 as mentioned above, the connecting trough 9 is at the same height as the discharge port 15, which facilitates the discharge of processed waste from the connecting trough 9 through the discharge port 15, thereby realizing material transfer in the waste treatment process.

[0043] The second connecting plate 13 is fixed inside the sorting cabinet body 1, serving as a divider and support. It provides an installation base for the discharge port 15 and the secondary filter screen 14, ensuring their stable position within the sorting cabinet body 1.

[0044] The discharge port 15 is fixed to one side of the second connecting plate 13 and is used to discharge the processed waste from the connecting groove 9 into the sorting cabinet body 1. It is the channel for waste output after processing, which facilitates the centralized collection and further disposal of the processed waste.

[0045] The secondary filter screen 14 is fixed to the inner walls on both sides of the second connecting plate 13. It filters the liquid that has entered the area after preliminary treatment again, further removing fine impurities from the liquid, improving the cleanliness of the drainage, achieving more efficient separation of liquid and solid waste, and reducing environmental pollution.

[0046] The cleaning mechanism is located inside the sorting cabinet body 1 and is specifically designed to push the waste contained in the liquid on the upper side of the connecting tank 9. Its function is to collect and transport the waste in the liquid for subsequent processing, such as pushing the waste to the discharge port 15 for discharge or guiding it to a specific processing area. This ensures that the liquid on the upper side of the connecting tank 9 can flow smoothly, while ensuring that the waste can be effectively processed, and preventing the accumulation of waste in the connecting tank 9 from affecting the operation of the equipment and the waste processing effect.

[0047] It should be noted that the specific model of motor 2 used shall be selected by those skilled in the art, and the above-mentioned motor 2 and other related technologies are all existing technologies, which will not be elaborated in this solution.

[0048] Please refer to the details. Figures 1-4 The cleanup organizations include:

[0049] Nut 8 is threaded onto the circumferential surface of lead screw 19;

[0050] The limiting sleeve 22 is threaded to the circumferential surface of the lead screw 19;

[0051] Push plate 20 is fixedly connected to the circumferential surface of limiting sleeve 22, and push plate 20 is slidably connected to the top of connecting groove 9;

[0052] The transmission assembly is located inside the sewage tank 5 and is used to drive one of the crushing sleeves 16 to rotate.

[0053] In this embodiment: When motor 2 starts, the power output by motor 2 drives lead screw 19 to rotate. When lead screw 19 rotates, nut 8 and limiting sleeve 22, which are threaded to it, will move axially on lead screw 19. Since push plate 20 is fixed on limiting sleeve 22, push plate 20 will move together with limiting sleeve 22, thereby pushing the waste in the liquid on the upper side of connecting groove 9 to move in a specified direction, such as conveying it towards discharge port 15.

[0054] Simultaneously, as the lead screw 19 rotates, the transmission gear 25 fixed on its circumferential surface also rotates. This transmission gear 25 is connected to another transmission gear 25 fixed on the circumferential surface of one of the crushing sleeves 16 via a toothed belt 21. Under the transmission action of the toothed belt 21, the crushing sleeve 16 is driven to rotate. The two crushing sleeves 16 mesh with each other, so the rotation of one crushing sleeve 16 will drive the other crushing sleeve 16 to rotate in the opposite direction, thereby crushing the solid waste in the sewage tank 5. Throughout the process, the conveying, pushing, and crushing operations of the waste are coordinated to achieve efficient waste processing by the environmentally friendly waste sorting cabinet.

[0055] Please refer to the details. Figures 1-3 The transmission components include:

[0056] There are two transmission gears 25, which are fixedly connected to the circumferential surface of the lead screw 19 and one of the crushing sleeves 16 respectively.

[0057] The toothed belt 21 is meshed with the circumferential surfaces of the two transmission gears 25.

[0058] In this embodiment: when the motor 2 starts and drives the lead screw 19 to rotate, the transmission gear 25 fixed on the circumferential surface of the lead screw 19 will rotate accordingly. Since the toothed belt 21 and the transmission gear 25 are connected in a transmission meshing connection, the rotating transmission gear 25 will drive the toothed belt 21 to move.

[0059] The other end of the toothed belt 21 is also connected to another transmission gear 25 fixed on the circumferential surface of the crushing sleeve 16. In this way, the movement of the toothed belt 21 will drive the transmission gear 25 to rotate, thereby causing the crushing sleeve 16 to start rotating.

[0060] Please refer to the details. Figure 2 The inner walls on both sides of the sewage trough 5 are fixedly connected to a connecting frame 18, and the top of the connecting frame 18 is fixedly connected to a fixing plate 11.

[0061] In this embodiment, the fixing plate 11 is fixed to the top of the connecting frame 18. It can serve as an installation platform for other components, such as control devices, sensors, or other auxiliary devices related to waste disposal, to ensure that these devices have a stable installation position inside the sorting cabinet body 1 and to ensure their normal operation.

[0062] Please refer to the details. Figures 1-4 A limit port is opened at the rear end of the classification cabinet body 1, and a limit plate 24 is installed in the limit port.

[0063] In this embodiment, the limiting plate 24 is installed inside the limiting port. The limiting plate 24 serves to restrict and position the components, possibly to limit the movement range of certain parts inside the sorting cabinet body 1 and prevent them from exceeding their normal working positions.

[0064] Please refer to the details. Figures 1-3 A protective cover 23 is fixedly connected to one side of the sewage trough 5. The protective cover 23 is fitted onto the circumferential surface of the toothed belt 21. Four limiting holes 101 are opened at the front end of the classification cabinet body 1.

[0065] In this embodiment: the protective cover 23 is fixed to one side of the drain trough 5 and fitted onto the circumferential surface of the toothed belt 21. Its main function is to protect the toothed belt 21, preventing external dust and debris from entering the meshing part between the toothed belt 21 and the transmission gear 25, ensuring the stability and reliability of the toothed belt 21 transmission, and extending the service life of the toothed belt 21. The four limiting holes 101 at the front end of the sorting cabinet body 1 may be used to install some detachable components or connect with other equipment, serving a positioning and fixing function, facilitating equipment assembly and maintenance.

[0066] Please refer to the details. Figures 1-4 Label stickers 17 are fixedly connected to both ends of the sorting cabinet body 1. First connecting plates 7 are fixedly connected to both ends of the two sorting cabinet bodies 1. A temperature sensor 6 is fixedly connected to one side of the sorting cabinet body 1. Two cover plates 4 are movably hinged to the top of the sorting cabinet body 1 through a hinge shaft. The two cover plates 4 are respectively movably snapped into the drainage trough 3 and the sewage trough 5. Second connecting sleeves 10 are fixedly connected to the inner walls on both sides of the drainage trough 3. A connection port 12 is opened on the lower inner wall of the sewage trough 5.

[0067] In this embodiment, the label 17 is fixed at both ends of the sorting cabinet body 1 and is used to affix relevant information on waste sorting, such as classification labels for recyclables, hazardous waste, kitchen waste and other waste, so as to facilitate users to dispose of waste correctly and improve the accuracy of waste sorting.

[0068] The first connecting plate 7 is fixed at both ends of the two sorting cabinet bodies 1. It may be used to connect multiple sorting cabinet bodies 1 to realize the combined use of multiple sorting cabinet bodies 1, expand the waste sorting processing capacity, and at the same time ensure the connection stability between multiple sorting cabinet bodies 1.

[0069] Temperature sensor 6 is fixed to one side of the sorting cabinet body 1 to monitor the internal temperature of the sorting cabinet body 1 in real time. When the waste generates heat during fermentation, decomposition, etc. inside the sorting cabinet body 1, causing the temperature to rise, temperature sensor 6 can detect it in time and send a signal to remind staff to take appropriate measures, such as ventilation and cleaning, to prevent safety hazards caused by excessive temperature or to affect the waste treatment effect.

[0070] The cover plate 4 is hinged to the top of the sorting cabinet body 1 via a hinge shaft, and is movably engaged with the drainage trough 3 and the sewage trough 5 respectively. The cover plate 4 can prevent garbage odors from spreading into the surrounding environment, and also prevent rainwater from entering the sorting cabinet body 1 and affecting garbage disposal. The cover plate 4 can be easily opened when garbage needs to be disposed of or equipment maintenance needs to be performed.

[0071] The second connecting sleeve 10 is fixed to the inner walls of both sides of the drainage trough 3, and may be used to connect drainage pipes or other equipment related to liquid discharge, so as to ensure that the liquid in the drainage trough 3 can be smoothly discharged from the sorting cabinet body 1.

[0072] Connection port 12 is located on the lower inner wall of the sewage tank 5 and may be used to connect to the sewage pipe to discharge the pre-treated sewage or solid waste in the sewage tank 5 into the sorting cabinet body 1, so as to realize the continuous treatment and discharge of waste.

[0073] The working principle and usage process of this utility model are as follows: When using this environmentally friendly garbage sorting bin, residents first place the relatively clear liquid garbage into the drainage trough 3 according to the classification labels 17 on both ends of the bin body 1, and place the liquid garbage containing more solid impurities and solid garbage into the sewage trough 5. The cover 4 is opened during disposal and closed afterward to prevent odors and rainwater from entering. The liquid garbage in the drainage trough 3 flows with the support and guidance of the connecting trough 9. After the liquid is filtered by the secondary filter screen 14 to remove fine impurities, it is discharged through the drainage pipe connected by the second connecting sleeve 10. Simultaneously, the motor 2 is started, driving the lead screw 19 to rotate, causing the nut 8 and the limiting sleeve 22 to move axially. The pushing plate 20 moves with the limiting sleeve 22, pushing the garbage contained in the liquid on the upper side of the connecting trough 9 towards the discharge port 15 for discharge. In the sewage discharge tank 5, the lead screw 19 rotates, driving the transmission gear 25, which in turn causes the crushing sleeve 16 to rotate via the toothed belt 21. The two meshing crushing sleeves 16 crush solid waste, and the crushed waste and sewage are discharged through the sewage discharge pipe connected to the connection port 12. During this process, the protective cover 23 protects the toothed belt 21. In addition, the temperature sensor 6 monitors the internal temperature of the sorting cabinet body 1 in real time and sends a signal when there is an abnormality. The limiting hole 101 at the front end of the sorting cabinet body 1 facilitates the installation of components or the connection of equipment, the limiting plate 24 at the rear end restricts the movement range of components, and the fixing plate 11 can be used to install auxiliary devices to ensure the operation of the equipment.

[0074] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
