Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a small-scale on-site treatment device for kitchen waste. Background Art

[0002] During the normal operation of a ship, especially ocean-going ships such as large container ships, bulk carriers, oil tankers, etc., the navigation time is usually several weeks to several months. Kitchen waste is produced from the organic waste generated during daily meal preparation and after meals in the ship's galley and dining room. The crew of a large ocean-going ship is configured with 25 - 30 people, and the daily production of kitchen waste is ≤ 30 kg. Since there is no special treatment device on board, the current treatment method is to collect and store it in the kitchen waste bin, and it needs to be transported to the shore receiving facility for further treatment when the ship docks at the shore. Due to the long navigation time and the relatively independent and limited space of the ship at sea, the accumulated kitchen waste in the bin often deteriorates and rots, emitting a stinking smell, which is extremely unpleasant to the visual and olfactory senses, attracting a large number of maggots and causing environmental pollution.

[0003] Countries are becoming increasingly strict with the environmental protection of the ocean and inland rivers. China attaches more importance to this aspect. The destinations of ship operations often require docking in various countries, and relevant departments, especially environmental protection departments, often board the ship for inspection when docking in the territorial waters of the host country. For the treatment equipment and devices used on board, if chemical methods, biochemical methods, etc. are adopted for treatment, a certain amount of chemical agents, microbial agents and other biochemical substances also need to be stored on board. These are relatively sensitive to environmental protection departments, and various certification documents related to their functions, components, etc. need to be submitted to the country of origin, with cumbersome procedures and long time-consuming, which is not conducive to the operation efficiency. Therefore, the treatment device on board should preferably adopt a physical method.

[0004] To sum up, in the field of on-site treatment of ship kitchen waste, there is still a lack of a small-scale on-site treatment device for kitchen waste, which can timely and locally treat the kitchen waste generated daily on board by physical means, realize the reduction, harmlessness and green environmental protection of kitchen waste, and eliminate problems such as the backlog and environmental pollution caused by the failure to timely treat the kitchen waste on board.

[0039] Most components of this device adopt mature products on the market, such as the small double-shaft crusher 2 (except that the knife teeth installed inside are three-lobed long knife teeth 201), the liquid-separated oil tank 9 (adopting products such as separated oil tanks and oil separation ponds on the market), small deodorization equipment 5, ozone disinfection machine 10, sight glass with scraper 12, movable caster with brake 17, fixed caster 18, footrest support 19, heat-conducting oil heating rod 303, stirring drive reduction motor 304, automatic exhaust valve 306, temperature sensor 308, etc.

[0040] Among them, the power and signals of the power equipment and sensor components such as the small double-shaft crusher 2, small deodorization equipment 5, ozone disinfection machine 10, heat-conducting oil heating rod 303, stirring drive reduction motor 304, and temperature sensor 308 installed on the device are transmitted into the operation panel control box 15, and functions such as starting, shutting down, emergency stop, forward and reverse control and display of the small double-shaft crusher 2 and the stirring drive reduction motor 304, temperature control and display, working state display, and fault display are realized through the control components, display screens, buttons and other electrical components in the operation panel control box 15.

[0041] Among them, the bottom heat-conducting oil drain port 307 (normally closed) of the heat-conducting oil jacket and heat-insulating layer 302 of the waste disposal bin 3 is for maintaining or replacing the heat-conducting oil; the heat-conducting oil filling port with cover 305 (normally closed) is for filling the heat-conducting oil; the automatic exhaust valve 306 is for timely discharging the gas that may be generated during the process of the heat-conducting oil temperature rising, so as to keep the inside of the heat-conducting oil jacket and heat-insulating layer 302 at normal pressure.

[0043] Among them, a pair of brake casters 17 and a pair of fixed casters 18 at both ends of the bottom of the frame 16 enable the device to move and turn flexibly, facilitating placement; the foot pedal support frames 19 at both ends inside each pair of casters have a height lower than that of the casters in the retracted state, which does not affect the operation of the casters and the passability of the device. When the foot pedal of the foot pedal support frame is stepped on, its raised height is higher than that of the casters, which can disable the casters. The bottom of the foot pedal support frame is a non-slip rubber pad, so that the device is fixed and cannot move; when the return rod of the foot pedal support frame is stepped on, the foot pedal support frame returns to the retracted state, and the casters are effectively functional.

[0044] The device of this embodiment is of an integrated structure, with a total height not greater than 115 cm and a total width of about 73 cm, which is convenient for personnel to operate and pass through the ship's cabin door.

[0045] The specific working method of this device is as follows:

[0046] The solid-phase-based kitchen waste materials generated from the leftovers on the dining tables in the ship's kitchen operation room and the crew's dining room are collected and poured into the kitchen waste solid-phase feed inlet 1, and enter the small double-shaft crusher 2 for physical crushing.

[0047] The crushed solid-phase materials enter the waste disposal bin 3, and the screw ribbon stirring shaft system 301 stirs, disperses, mixes, heats and dries the materials. The heating method of the waste disposal bin 3 is jacketed heat-conducting oil heating. The heat-conducting oil is heated by the heat-conducting oil heating rod 303 in the heat-conducting oil jacket and the lower part of the heat-insulating layer 302. Temperature sensors 308 are installed in the upper middle parts on both sides of the heat-conducting oil jacket and the heat-insulating layer 302 and in the upper middle part of the waste disposal bin 3, and the signals are transmitted to the operation panel control box 15 to control the working temperature in the bin at 60 - 80 °C. During the heating and drying process in the waste disposal bin 3, the harmful bacteria in the materials are killed, and the moisture is dried to a moisture content of about 13%. An organic matrix raw material is formed. By opening the door-type discharge port 309, the organic matrix raw material is bagged and sealed, and then stored until it is transported to the shore receiving facility when the ship arrives at the shore and then enters the organic fertilizer production plant for further processing into organic fertilizers and feeds, realizing the in-situ physical, harmless and reduction treatment of kitchen waste on the ship.

[0048] The gas generated during the heating and drying process in the waste disposal bin 3 is connected to the ship's kitchen exhaust system after passing through the small deodorization device 5.

[0049] For the kitchen waste with a liquid-phase-based kitchen soup generated from the leftovers on the crew's dining room tables, it is collected and poured into the liquid-phase (with a flip cover) liquid inlet 7 of the kitchen soup, enters the built-in handle basket 8, and through the uniformly distributed and dense water-permeable small holes on the basket, the liquid-phase substances enter the lower liquid separation fuel tank 9. The handle basket 8 separates the solid-phase materials in the soup, and after being taken out, it is poured into the kitchen waste solid-phase (with a flip cover) feed inlet 1 and enters the waste disposal bin 3 for the above-mentioned solid-phase disposal.

[0050] The liquid entering the liquid-separated oil tank 9 is passed through the ozone disinfection machine 10 via the ozone gas delivery pipeline 11, and ozone (O 3 ) gas is sent into the liquid-separated oil tank 9. The ozone disinfection principle is used to disinfect and sterilize the liquid in the tank, realizing the harmlessness of the liquid; the liquid-separated oil tank 9 conducts physical oil separation and discharges waste oil and sewage respectively; the liquid-separated oil tank 9 is a common oil separation tank or oil interceptor product in the market. Through the internal oil separation plates, baffles and other structures, the oil is isolated in the oil separation area of the oil separation tank and discharged through the oil discharge port 13 into a closed collection container, stored until it is transported to the shore receiving facility when approaching the shore and then enters the waste oil processing plant to be reprocessed into biodiesel; the sewage is isolated in the water outlet area of the oil separation tank and discharged through the drain port 14 to the kitchen drainage system, enters the ship's sewage holding tank (also known as the grey water tank), and is transported to the shore receiving facility when approaching the shore and then enters the sewage treatment facility or sewage treatment plant for treatment.

[0051] Through physical oil separation, oil-water separation, ozone disinfection and sterilization, the above-mentioned liquid-phase substances achieve the harmlessness of sewage and the separate collection of waste oil.

[0052] In summary, this device occupies a small area, is suitable for installation in the ship's cabin space, can be moved or fixed, is convenient and flexible, easy to operate. Most of the components of the device use mature products in the market, and the device structure is relatively compact and simple, and is easy to implement.
