Description

A kind of catering wastewater oil-water separator

technical field

The invention belongs to the technical field of catering wastewater treatment equipment, and in particular relates to a catering wastewater oil-water separator.

Background technique

The device used for oil-water separation has the advantages of environmental protection in many fields. It is well known that whether it is catering wastewater or wastewater from factories and slaughterhouses, it will eventually be discharged into the sewer network. Over time, it will not only lead to blockage of sewer pipes, resulting in sewage overflow, but also It has seriously affected people's lives, and the oil-water separator separates oil and sewage, and the sewage is directly discharged into the sewer network, which not only reduces pollution to sewers and the environment, but also protects water resources.

However, most of the traditional oil-water separation devices can only simply block a certain degree of oil pollution from entering the pipe network, and have the characteristics of incomplete oil separation, difficult cleaning of equipment, and poor corrosion resistance, which are rejected by many enterprises. In addition, in the relatively cold winter in the north, oil-water separation devices that are not designed comprehensively may even cause grease to solidify at the pipes, causing sewer sewage to overflow, which not only pollutes the production and living environment, but also increases unnecessary dredging expenses.

Even in the colder winter in the north, there will be no phenomenon of oil solidification at the pipes and overflow of sewer sewage, which is environmentally friendly and low in cost.

As a further improvement, a cover plate is provided on the catering wastewater treatment pool, and a handle is provided on the cover plate. When cleaning the device, open the handle and open the cover directly, and use it for general restaurant drainage to clean once every 3 months.

As a further improvement, the outer wall of the catering wastewater treatment pool is provided with a horizontal frame along the circumference, and the horizontal frame functions as a handle for easy transportation.

As a further improvement, both the screen and the corrugated plate coalescer can be detachably arranged in the right oil collection chamber, which is convenient for disassembly and cleaning.

As a further improvement, the inner wall of the oil collecting barrel is provided with a hook, and the edge of the oil collecting plate is provided with buckles, and the hook and the buckle are arranged in cooperation so that the oil collecting plate can be detachably arranged in the oil collecting barrel, which is convenient for disassembly and assembly.

As a further improvement, the catering wastewater treatment pool, cover plate, screen, corrugated plate coalescer, oil collecting barrel and oil collecting plate are all made of stainless steel, which has good anti-corrosion effect and prolongs the service life.

As a further improvement, the screen is provided with convenient buckles for easy disassembly and cleaning.

As a further improvement, the communication nozzles through which the oil collection chamber, the middle oil collection chamber and the left oil collection chamber communicate in sequence are located at the lower end of the partition.

As a further improvement, the oil collecting plate is formed by fixedly connecting and superimposing multiple layers of separators, and the distance between two adjacent layers of separators is 2-5 mm.

Compared with prior art, the beneficial effect of the present invention is:

The oil separator of the present invention can achieve the effect of complete oil separation after repeated isolation, and the equipment is easy to clean and has strong corrosion resistance. Even in the colder winter in the north, there will be no phenomenon of oil solidification at the pipes and overflow of sewer sewage, which is environmentally friendly and low in cost.
