Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of canteen waste treatment devices, and more specifically, to a green campus canteen waste treatment device. Background Technology
[0002] A school canteen generally refers to a place where a school prepares meals for its students or faculty. Most school canteens primarily serve three meals a day to students and faculty, but some are open to the public.
[0003] Food waste generated in school canteens mainly consists of leftover food from diners. To facilitate unified management, some canteens require diners to voluntarily pour the remaining food from their trays into food recycling bins. However, food residue and blockages easily occur at the openings of these recycling bins, affecting the normal use by subsequent diners. Therefore, we have proposed a green campus canteen waste disposal device to solve the above-mentioned problems. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a green campus canteen waste disposal device. A booster pump is fixedly connected to the surface of the bucket lid. Through an external pipe, the water spray end of the booster pump is connected to a water spray connector, and the water suction end of the booster pump is connected to a water supply pipe. A control button electrically connected to the booster pump is installed on the surface of the bucket lid. A guide plate is inserted into the surface of the bucket lid, and a water spray connector is inserted through the surface of the guide plate. The insertion end of the water spray connector is connected to a water spray pipe, and the spray nozzle of the water spray pipe is connected to a high-pressure nozzle. After diners finish eating, they pick up the tray and pour the leftover food onto the surface of the guide plate. When the surface of the guide plate is used for a long time and there is residue and accumulation of leftover food, the booster pump is activated. The pressurized water is sprayed onto the surface of the guide plate along the high-pressure nozzle of the water spray pipe, accelerating the falling of the leftover food. The recycling bin collects and processes the food.
