Description

Technical Field

[0001] This application belongs to the field of oily wastewater treatment technology, specifically an oil-water separation and filtration device that is easy to adjust. Background Technology

[0002] The industrial production process of instant noodles generally includes kneading, rolling, shredding, cutting, steaming, drying, and cooling. Currently, there are two types of instant noodles on the market: fried and non-fried. Existing production of cup noodles typically uses small-bag dispensing machines, a type of packaging equipment widely used in the food and beverage industries. These machines cut consecutive small packages (desiccants, seasoning packets, etc.) and dispense individual small packages into the cup noodles, thus completing the packaging. An oil-water separator is a device, divided into catering oil-water separators and industrial oil-water separators. Catering oil-water separators are used in the catering industry to treat wastewater; due to environmental protection requirements, wastewater discharged into rivers, lakes, seas, and from ship machinery must be treated, requiring the use of industrial oil-water separators. Oily wastewater has adverse effects on humans, animals, plants, and even the entire ecosystem. Its harm is mainly manifested in the following two aspects: 1. Harm to enterprises. Wastewater containing emulsified oil will settle along with suspended particles and iron oxide scale in process facilities and pipelines, forming highly viscous sludge clumps that clog pipes and equipment, affecting normal production. 2. Environmental hazards. The environmental impact of oils is multifaceted. For example, they pollute water bodies, forming oil films on the surface that hinder reoxygenation. Reduced dissolved oxygen limits algal photosynthesis, impacting the normal growth of aquatic organisms, giving them an oily smell or toxicity, and even causing foul odors, thus destroying the utilization value of water resources. Oil adhering to fish gills can suffocate them; at a concentration of 200 mg / L, fish cannot survive. Adhesion to algae and plankton can kill them. Oils inhibit egg-laying and hatching in waterbirds, potentially causing mass bird deaths. Irrigating farmland with oily wastewater causes oil and its derivatives to cover the soil and plant surfaces, clogging soil pores, preventing air penetration, and hindering normal soil and microbial metabolism. This reduces the quality and value of agricultural products, potentially leading to crop yield reduction or death. Furthermore, oil migration down the soil can cause serious groundwater pollution. In conclusion, oily wastewater pollution can cause devastating damage to ecosystems and poses potential harm to human health.

[0003] For example, CN209475753U discloses an oil-water separator, including a separation box. A partition is located in the middle of the separation box. A drain valve is installed in the middle position near the bottom on the left side of the partition. A funnel is installed near the bottom on the left side of the partition, with the drain valve located in the middle of the funnel. A water inlet is installed above the liquid level on the upper left side of the separation box. An oil suction pipe is installed on the partition near the liquid level. A gas-liquid mixing pump is installed at the bottom of the right side of the partition and is fixed inside the separation box by a bracket at the bottom. This utility model provides a conveniently adjustable oil-water separation and filtration device with a clever and reasonable structure. The observation window on the separation box facilitates the extraction of remaining oil. Injecting clean water raises the oil level, allowing the oil to be drawn away. The scale lines on the observation window further assist the operator, improving the accuracy of liquid level control during oil-water separation and ensuring its efficiency.

[0004] However, in this application, when a large amount of oily wastewater enters the oil-water separator, it contains other particulate impurities, which makes cleaning difficult for staff and increases their workload. Utility Model Content
