Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology for offshore platforms, and provides a device for treating domestic waste on offshore platforms. Background Technology

[0002] Domestic waste on offshore platforms mainly originates from the daily living waste generated by platform staff, including food scraps, paper, and plastics. Environmental regulations require that this waste be unloaded onto recycling vessels and transported back to land for processing. Because offshore platforms are far from land, waste transfer and processing are challenging; therefore, specialized equipment and technologies are needed for the treatment of domestic waste on offshore platforms.

[0003] Currently, the main methods for transferring and processing domestic waste on offshore platforms include waste collection, sorting, and storage. Waste collection refers to collecting domestic waste from the platform; sorting refers to classifying waste according to different types; and storage refers to storing waste in garbage bins. At present, offshore platforms pack kitchen waste into garbage bags and then transport it back to land for centralized processing by waste transport ships. This not only incurs significant transportation costs but also results in high costs for land-based disposal.

[0004] Currently, the transfer of domestic waste from offshore platforms requires cranes and cargo cages to lift it onto recycling vessels. Due to the untreated waste and its large size, the lifting time is excessively long, the loading and unloading work is strenuous, and recycling vessels and transport vehicles need to make frequent trips, resulting in a waste of human resources and continuously increasing transportation costs. During the continuous transfer process, some waste falls off and pollutes the marine environment. Therefore, on-site treatment of domestic waste from offshore platforms is crucial.

[0005] Offshore platform domestic waste management is of great significance for protecting the marine ecological environment. Effective waste management can reduce the damage caused by waste to the marine ecosystem, protect the survival and reproduction of marine life, and maintain the stability and health of the marine ecosystem. With increasing environmental awareness and technological advancements, offshore platform domestic waste management technology will continue to develop and improve, waste management equipment will become more intelligent and efficient, and waste management methods will become more environmentally friendly and sustainable.

[0006] The existing technologies for municipal solid waste treatment are as follows:

[0007] A household waste recycling and processing device, application number: CN202310814896.6. This utility model discloses a household waste recycling and processing device, including a processing bin. A mounting frame is fixedly connected to the top end of the processing bin, and a rotating rod is rotatably connected to the bottom of the mounting frame. One bottom end of the rotating rod extends into the interior of the processing bin, and elastic rods are evenly installed on the bottom end of the rotating rod. A stirring rod is fixedly connected to the end of the elastic rod away from the rotating rod. A stirring motor is fixedly connected to the top of the mounting frame. This utility model relates to the technical field of household waste processing equipment. This household waste recycling and processing device achieves the purpose of changing the stirring angle during the stirring process, enabling thorough stirring and crushing of household waste in different locations. It improves the safety of use, automatically retracts the stirring protrusions when the equipment stops working to prevent accidental injury to workers, facilitates the cleaning of household waste in the equipment's crevices, and prevents household waste from accumulating and adhering to the bottom of the equipment.

[0008] This utility model mainly relates to a mixing and crushing process for municipal solid waste. It can only perform preliminary treatment of municipal solid waste, and provides automatic equipment retraction and personnel protection. It is effective in cleaning the equipment and preventing waste adhesion. This utility model is suitable for large-scale mixing and crushing of municipal solid waste; for small-volume platform waste, it can only be processed intermittently. No beneficial effects have been observed in solid-liquid separation and automatic feeding to reduce labor intensity. It cannot effectively reduce the mass and volume of municipal solid waste, nor can it effectively purify the odor generated by the waste. The mechanical transmission and connection structure is simple, the degree of electrical automation is low, requiring manual control and adjustment. The equipment is placed outdoors and cannot cope with marine climate conditions. The equipment occupies a large space and cannot be applied to municipal solid waste treatment on offshore platforms. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by proposing a domestic waste treatment device for offshore platforms. This addresses the current lack of domestic waste treatment equipment on offshore platforms, requiring waste to be periodically transported back to land for processing by recycling vessels. Existing land-based domestic waste treatment devices suffer from the following drawbacks: low level of electrical automation; low equipment protection level and large space occupation; inability to purify harmful gases and separate solid and liquid waste; and lack of automatic feeding, drying, and compression functions. These land-based domestic waste treatment devices are unsuitable for the offshore environment and operational requirements, cannot significantly reduce the weight and volume of waste for harmless treatment, and cannot save platform waste storage space.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a marine platform domestic waste treatment device, comprising a shell, wherein the shell is provided with a feeding port, the feeding port and the shell are sealed together, and a multi-stage waste treatment mechanism is provided downstream of the feeding port, the multi-stage waste treatment mechanism being integrated and installed inside the shell.

[0011] Furthermore, the top of the housing is equipped with a waste deodorization device; the multi-stage waste treatment mechanism includes a solid-liquid separation mechanism, a waste vibrating screening mechanism, a waste crushing mechanism and a conveying mechanism arranged sequentially below the feeding port, and a waste compression mechanism is provided downstream of the conveying mechanism.

[0012] Furthermore, a tilting and lifting mechanism is provided on one side of the feeding port.

[0013] Furthermore, the tilting and lifting mechanism is a chain-type single-bucket elevator or an electric vertical garbage bin elevator.

[0014] Furthermore, the solid-liquid separation mechanism is a dry-wet waste separator.

[0015] Furthermore, the waste vibrating screening mechanism is a waste vibrating screen.

[0016] Furthermore, the waste pulverizing mechanism is a waste shredder.

[0017] Furthermore, the waste compression mechanism is a vertical waste compression box.

[0018] Furthermore, the conveying mechanism is a high-temperature resistant conveyor belt.

[0019] Furthermore, it also includes a drying mechanism, which is mounted above the high-temperature resistant conveyor belt.

[0020] Furthermore, the drying mechanism is an electric heating coil.

[0021] The beneficial effects of this utility model are as follows: This device is suitable for the harsh environment of offshore platforms and can promptly process domestic waste generated on the platform, with a working efficiency 1-2 times that of similar waste treatment devices. It has multiple automated functions, effectively reducing manual labor intensity, and can process more than 1 ton of domestic waste per day. It effectively reduces the space occupied by domestic waste on the platform, saves the frequency of unloading waste from garbage vessels, eliminates pollution of the environment by domestic waste, and protects the health of platform personnel.

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

[0024] Example 1

[0025] A domestic waste treatment device for offshore platforms mainly consists of a shell 23, a solid-liquid separation mechanism, a waste vibrating screen 4, a waste crusher 5, a conveying mechanism, a waste compression mechanism, a deodorization system 24, a drying mechanism, and a tilting and lifting machine 2.

[0026] The housing 23 is a sealed box, with a feeding port 1 and a deodorization system 24 installed on the top surface; the feeding port 1 and the housing 23 are sealed together to prevent gas from escaping; the deodorization system 24 is an adsorption deodorization device or an ion deodorization device, with an air inlet and an air outlet; the air inlet is connected to the box and is also sealed together with the housing 23.

[0027] The tilting and lifting mechanism 2 is a chain-type single-bucket elevator or an electric vertical garbage bin 7 elevator, which is set on one side of the feeding port 1. It is used to lift the garbage bin 7 placed on the ground to the height of the feeding port 1, and then tilt it to pour the garbage in the garbage bin 7 into the feeding port 1. The garbage enters the solid-liquid separation mechanism through the feeding port 1.

[0028] The solid-liquid separation mechanism is a dry and wet waste separator 3, preferably an inclined screen dry and wet separator. The separated wastewater enters the sewage pipe, and the separated dry waste flows down and falls into the waste vibrating screen 4 separation mechanism.

[0029] The waste vibrating screen 4 is a waste vibrating screen 4 that uses vibration to further remove water from the waste after dry and wet separation. The wastewater enters the sewage pipe and is connected to the sewage valve 6 located outside the housing 23 to discharge the wastewater. The waste after vibrating screening falls into the waste crusher 5.

[0030] The waste crushing mechanism is a waste shredder 5, which is used to crush the waste after it has been vibrated and screened. The crushed waste then falls into the conveying mechanism.

[0031] The conveying mechanism is a high-temperature resistant conveyor belt. The working belt of the high-temperature resistant conveyor belt can be an ordinary heat-resistant conveyor belt or a high-strength heat-resistant conveyor belt. The high-strength layer of the ordinary heat-resistant conveyor belt is polyester-cotton canvas (CC56), and the high-strength heat-resistant conveyor belt is EP (specifically divided into EP100, EP150, EP200, EP250, EP300, EP350, EP400, EP450, EP500, etc.). It is installed below the aforementioned equipment to receive the crushed waste and continue to transport the crushed waste downstream to the waste compression mechanism. A drying mechanism is installed above the conveying section before entering the waste compression mechanism.

[0032] The drying mechanism is an electric heating coil 11, which is mounted on the high-temperature resistant conveyor belt with a bracket. The spacing between the coils is preferably 15-30 cm to ensure effective drying of the waste located on the high-temperature resistant conveyor belt.

[0033] The waste compression mechanism is a vertical waste compression box 15, which adopts a vertical compression process. The waste is compressed powerfully through a hydraulic system. The compressed waste is sent to the inlet 17 through the outlet 16 of the vertical waste compression box 15 to complete the waste processing.

[0034] Example 2

[0035] like Figure 1 As shown, a domestic waste treatment device specifically designed for offshore platforms can effectively classify and treat domestic waste generated by offshore oil operations platforms in a harmless manner, and significantly reduce the space occupied by the offshore platform through compression and packaging. The device consists of several key components, including a feeding port 1, a tilting elevator 2, a dry and wet waste separator 3, a waste vibrating screen 4, a waste crusher 5, a drying box 12, a vertical waste compression box 15, a discharge port 16, a hydraulic oil tank 19, a control box 21, a shell 23, and a deodorization system 24.

[0036] Specifically, the tilting elevator 2 of this device has flexible movement capabilities, enabling it to smoothly raise and lower the garbage bin 7, and also features a tipping function. To ensure operational precision, the tilting elevator 2 is equipped with two limit switches: a feed inlet 1 opening sensor switch and a material stop sensor switch. When the garbage bin 7 reaches the position indicated by the feed inlet 1 opening sensor switch, the cover of the feed inlet 1 will automatically open. Subsequently, the garbage bin 7 continues to move until the material stop sensor switch is activated, at which point the tilting elevator 2 will tilt the material cart, allowing the household waste to smoothly pass through the feed inlet 1 into the wet and dry waste separator 3.

[0037] The inlet of the wet and dry waste separator 3 is connected to the bottom of the feed inlet 1, while the outlet is connected to the waste vibrating screen 4. The waste vibrating screen 4 is driven by a motor 25 to achieve solid-liquid separation. Waste liquid flows into the waste shredder 5 through holes at the bottom of the waste vibrating screen 4, and a drain pipe is provided at the bottom of the waste shredder 5. An automatic control valve is installed at the outlet of the drain pipe, which automatically opens when the waste vibrating screen 4 starts working and automatically closes when the waste vibrating screen 4 stops working. After the waste vibrating screen 4 starts, solid waste is poured into the waste shredder 5.

[0038] The garbage shredder 5 has multiple shredding blades 10 evenly arranged inside, and a multi-functional baffle and high-temperature resistant conveyor belt 8 are installed at the bottom. When material is detected, the shredding blades 10 will automatically start and stop automatically after a set time. At the same time, the baffle 9 and the high-temperature resistant conveyor belt 8 will open, conveying the shredded solid waste to the drying chamber 12.

[0039] The drying chamber 12 is closely connected to the waste shredder 5, and both are equipped with high-temperature resistant conveyor belts 8 at the bottom. The drying chamber 12 is internally equipped with an electric heating coil 11 and a germicidal lamp 13. Based on the working time of the waste shredder 5, the electric heating coil 11 and the germicidal lamp 13 will be turned on in advance for preheating and will automatically stop after a set time. Subsequently, the high-temperature resistant conveyor belt 8 will open, conveying the dried and sterilized solid waste to the vertical waste compression box 15.

[0040] The vertical waste compression container 15 is equipped with a discharge port 16, a hydraulic device 27, and a hydraulic tilting plate 14. The hydraulic oil of the hydraulic device 27 and the hydraulic tilting plate 14 is connected to the outlet of the hydraulic pump 26, while the inlet of the hydraulic pump 26 is connected to the hydraulic oil tank 19. The hydraulic oil tank 19 is equipped with a level gauge 20 for real-time monitoring of the hydraulic oil level. When material is detected, the hydraulic pump 26 automatically starts, the hydraulic device 27 compresses the processed waste, and the hydraulic tilting plate 14 automatically pushes the compressed solid waste through the discharge port 16 to the receiving port 17. Workers can then simply open the door on the receiving port 17 to remove the compressed solid waste.

[0041] In addition, to reduce environmental pollution, the top of this device is specially designed with a deodorization system 24 to filter the exhaust gas generated during the treatment of domestic waste.

[0042] Example 3

[0043] A domestic waste treatment device for offshore platforms features automated waste processing capabilities. The device includes a tilting elevator 2, which is fixedly mounted above a housing 23. The tilting elevator 2 is connected to a feed inlet 1 via a conveyor chain, ensuring smooth entry of waste into the treatment system. Below the feed inlet 1 is a wet / dry waste separator 4, which effectively separates solids and liquids from the waste. The wet / dry waste separator 4 is also connected to a vibrating screen 4, which further screens the waste to ensure effective separation. The vibrating screen 4 is designed to open and close automatically and is fixed to the housing 23 for easy maintenance and operation. The vibrating screen 4 is powered by a motor 25, which drives the vibrating screen 4 to perform waste vibration and screening.

[0044] The garbage shredder 5 is fixed to the housing 23, and has multiple shredding blades 10 evenly distributed inside for shredding solid waste into smaller particles. An automatic drain line is installed at the bottom of the garbage shredder 5, which is connected to a drain valve 6 to ensure smooth wastewater discharge. The drain valve 6 can automatically open and close as needed to control wastewater discharge. A baffle 9 is also installed at the bottom of the garbage shredder 5, which can automatically flip to transfer the shredded garbage to a high-temperature resistant conveyor belt 8. The high-temperature resistant conveyor belt 8 is fixed to the bottom of the garbage shredder 5 and the drying chamber 12, and is used to convey the shredded garbage to a vertical garbage compression chamber 15.

[0045] The drying chamber 12 is fixed to the housing 23 and contains a germicidal lamp 13 and an electric heating coil 11 for drying and sterilizing the pulverized waste. The drying chamber 12 ensures that the waste meets hygiene standards during processing, preventing bacterial growth. A conveyor belt 8 transports the pulverized waste to a vertical waste compression box 15. The vertical waste compression box 15 contains a hydraulic flap 14 and a hydraulic device 27, which provides pressure through hydraulic lines 18 to compress the waste. The vertical waste compression box 15 also has a discharge port 16 for ejecting the compressed waste.

[0046] Hydraulic pump 26 is connected to hydraulic oil tank 19 and hydraulic pipeline 18. Hydraulic oil tank 19 is equipped with a level gauge 20 to monitor the hydraulic oil level in real time, ensuring the normal operation of the hydraulic system. Discharge port 17 is installed on the outside of housing 23 and connected internally to vertical waste compression box 15, facilitating the removal of compressed waste by workers. Deodorization system 24 is installed on the top of housing 23 to treat odors generated during waste processing, ensuring a clean working environment.

[0047] The control box 21 is installed on the outside of the housing 23 and is connected to various components via control cables to achieve automatic control of the entire device. The control panel 22 is installed on the outside of the control box 21 for easy operation and monitoring by operators. The control panel 22 can display the operating status of the device and allow for the setting and adjustment of various parameters.

[0048] When the device is in operation, household waste is first placed in the waste bin 7. The operator starts the tilting elevator 2 via the control panel 22, which transports the waste bin 7 to the feeding port 1. When the feed cover of the feeding port 1 senses the arrival of the waste bin 7, it automatically opens, and the waste bin 7 continues to move until the material stop sensor switch. At this point, the tilting elevator 2 tilts the material cart, and the household waste enters the dry and wet waste separator 4 through the feeding port 1. The motor 25 automatically starts when the waste bin 7 reaches the material stop sensor switch, driving the waste vibrating screen 4 to vibrate, thereby achieving solid-liquid separation of the household waste. The separated wastewater is discharged into the platform's sewage pipe through the drain valve 6.

[0049] After separation, the garbage vibrating screen 4 opens, and solid waste falls into the garbage shredder 5. The shredder head 10 then automatically starts working, shredding the solid waste into smaller particles. After shredding, the baffle 9 opens, and the shredded solid waste falls into the high-temperature resistant conveyor belt 8, which transports the shredded waste to the drying chamber 12. The electric heating coil 11 and the germicidal lamp 13 in the drying chamber 12 start working to dry and sterilize the waste. When the drying time reaches the preset temperature, the high-temperature resistant conveyor belt 8 transports the dried waste to the vertical garbage compression box 15.

[0050] Hydraulic pump 26 automatically starts, transferring hydraulic oil from hydraulic tank 19 to hydraulic device 27 and hydraulic flap 14 via hydraulic line 18. Hydraulic device 27 automatically compresses the pulverized solid waste. After compression, hydraulic flap 14 pushes the compressed solid waste through discharge port 16 to collection port 17. Workers can then open the door on collection port 17 to remove the compressed waste. Deodorization system 24 automatically starts when the device starts and automatically stops when the device stops to maintain a clean and hygienic working environment.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
