Description

TECHNICAL FIELD

[0003] In the existing train catering waste treatment process, there are two major problems:

[0004] Unclear garbage classification, subsequent processing difficult: the current garbage cans on the train are mostly single storage structures, which cannot effectively classify garbage with liquid (such as leftover soup and fruit peels) and dry garbage (such as packaging paper and empty plastic bags). After the mixed storage of the two types of garbage, the liquid easily penetrates into the dry garbage, not only increasing the weight of the garbage bag and making it easy to break, but also producing odors and breeding bacteria during transportation and subsequent processing, greatly increasing the difficulty and cost of subsequent sorting, cleaning, and processing of garbage;

[0005] Garbage collection method is inefficient and easy to cause secondary problems: train staff usually use the traditional method of carrying plastic bags when collecting passenger-generated catering waste. As the garbage continues to accumulate, the weight of the plastic bag gradually increases, and the plastic bag is prone to breakage, causing the garbage to scatter inside the train compartment, not only polluting the compartment environment, but also requiring additional manpower to clean up, which seriously reduces the overall work efficiency of train catering waste treatment, and may also affect the passenger experience;

[0020] 3. It has anti-odor function to protect the environment of the car: The device is provided with a special valve plate assembly in the funnel groove, which can effectively block the upward diffusion of sewer odor. When liquid is discharged, the water flow falls to the lower cylinder along the pressure film after entering the main cylinder, and under the action of gravity and impact force, the opening and closing valve plate is opened, and the first fixed magnetic core and the first moving magnetic core are attracted to separate the second supporting rod and the transmission connecting rod, ensuring smooth discharge of the liquid. When there is no liquid discharge, the pressure above the opening and closing valve plate is greater than that below, the pressure film pushes the transmission connecting rod against the second supporting rod, and the second fixed magnetic core and the second moving magnetic core are attracted to fix the bearing plate, so that the opening and closing valve plate tightly covers the sealing ring at the lower end of the lower cylinder, forming a reliable seal and completely preventing sewer odor, ensuring the air hygiene in the train car.

[0021] 4. Integrated cleaning function to improve the practicality of the device: The wash basin and faucet fixedly installed on the upper wall of the carrier can meet the needs of passengers and train restaurant utensil cleaning at the same time. The sewage generated by cleaning is directly discharged through the first drain pipe, without the need for additional cleaning facilities. The device has garbage disposal and cleaning functions, high integration degree, saves train internal space, and improves the comprehensive practicality of the device. BRIEF DESCRIPTION OF DRAWINGS

[0042] The air vent grooves 31 are used to prevent the cart 6 from being closed when the bearing cylinder 27 is placed, and prevent the garbage bag from bulging.

[0043] The embodiment is further provided with a valve plate assembly including a main cylinder 33 and a bearing plate 34, a lower cylinder 35 is fixedly installed on the main cylinder 33, an inclined plate 36 is fixedly installed between the main cylinder 33 and the lower cylinder 35, an opening is formed in the inclined plate 36, a transmission connecting rod 37 is inserted into the opening, a baffle 38 is fixedly installed at the upper end of the transmission connecting rod 37, a pressure film 39 is fixedly installed between the main cylinder 33 and the lower cylinder 35 and above the inclined plate 36, the baffle 38 is in contact with the pressure film 39, a pair of support rods 40 are fixedly installed on the lower wall of the inclined plate 36, hooks 41 are fixedly installed at the lower ends of the support rods 40, respectively, ear rods 42 are fixedly installed on the front and rear walls of the bearing plate 34, respectively, the ear rods 42 are rotatably installed in the hooks 41, a magnetic core support 43 is obliquely installed between the pair of support rods 40 and above the hooks 41, a first fixed magnetic core 44 is fixedly installed on the magnetic core support 43, a second fixed magnetic core 45 is fixedly installed on the magnetic core support 43 and on one side of the first fixed magnetic core 44, a second support rod 46 is fixedly installed at one end of the bearing plate 34, the upper end of the second support rod 46 is in contact with the lower end of the transmission connecting rod 37, an on-off valve plate 47 is fixedly installed at the other end of the bearing plate 34, a first moving magnetic core 48 and a second moving magnetic core 49 are fixedly installed on the bearing plate 34 and on one side of the second support rod 46 from left to right, respectively, the first moving magnetic core 48 is matched with the first fixed magnetic core 44, and the second moving magnetic core 49 is matched with the second fixed magnetic core 45.

[0045] When the water flows into the funnel groove 12, the water flows into the main cylinder 33 and falls into the lower cylinder 35 along the inclined surface of the pressure film 39. Due to the accumulation of water in the lower cylinder 35, the mass is large, and under the action of gravity, the opening and closing valve plate 47 is pushed to open, and the opening and closing valve plate 47 exerts a pushing force on the bearing plate 34, so that the bearing plate 34 rotates around the hook 41 under the action of the ear lever 42, and the first fixed magnetic core 44 is attracted to the first moving magnetic core 48.
