Description

Technical Field

[0001] The utility model relates to a grease separator for a restaurant in a high-speed service area. Background Art

[0002] The discharge of catering wastewater has increased year by year, showing a growing trend.

[0003] In order to solve the above problems, grease traps came into being and are widely used in large-scale shopping malls, office buildings and other commercial restaurants to separate oil from kitchen drain pipes. They are essential grease traps in the kitchen. These grease traps are usually installed in the basement of large-scale shopping malls, office buildings, etc. or buried under the restaurant kitchen, so that the total drainage pipe of the restaurant kitchen is higher than the wastewater inlet of the grease trap, so that the wastewater can flow into the grease trap by gravity.

[0004] However, for highway service areas, since highway service areas are usually built directly on the ground without an underground layer, it is impossible to install grease traps directly in the underground layer. If the grease trap is buried and installed under the restaurant kitchen, the grease trap itself is large in size and space for manual slag discharge is required. Therefore, a relatively large foundation pit needs to be excavated, and a transportation channel connected to the ground above needs to be reserved for the foundation pit. This results in a complex foundation pit structure, a large amount of civil engineering excavation, and complex and costly civil construction. In addition, if the grease trap is installed under the restaurant kitchen, staff also need to regularly transport slag to the ground above, and the up and down slope difference makes transportation more laborious and inconvenient.
