Description

[Detailed Description of the Invention] The present invention relates to a grease collector that can efficiently separate and collect oil from waste water mixed with oil such as grease.

Grease collectors have traditionally been used as devices to separate oil from wastewater, but they consist of a box with multiple partition walls arranged in a staggered manner to form long passages, and while the wastewater passes through these passages, the water is removed. The oil is separated using the difference in specific gravity between the oil and oil, and the longer the passage, that is, the greater the number of partition walls, the higher the oil collection efficiency.
As the number of partition walls increases, not only does the capacity for treating wastewater per unit time decrease, but also the material and processing costs become expensive, and it becomes more troublesome to attach and remove the partition walls during cleaning. There were some shortcomings.

However, in order to eliminate and solve the above-mentioned drawbacks, the present invention provides a box 2 with a drainage outlet ₂₁ at one end.
The inside of the grease collector is partitioned into a drainage intake chamber 5 and a drainage chamber 6 by two partition walls 3 and 4, respectively, and a drainage passage is formed between the lower ends of the partition walls 3 and 4 and the bottom plate ₂₂ of the box. 1, characterized by a structure in which a partition wall 7 having a tongue piece 7 ₁ and an opening 7 ₂ that slopes upward from below toward the partition wall 3 side is inserted between the partition walls 3 and 4. It is.

The partition wall 7 is made by punching out an L-shape from one end of a metal plate and cutting this part up at approximately 45 degrees to form the tongue piece ₇₁ , and the cut out part forms the opening 7. It becomes ₂ . In the figure, 8 is a filter bucket that filters out solid matter contained in the waste water.

Next, in accordance with the above configuration of the present invention, the specific usage, operation, and effects of the grease collector of the present invention will be explained with reference to the illustrated embodiments.

That is, when wastewater containing a mixture of water and grease to be disposed of is introduced from above into the intake chamber 5 of the box 2,
The drainage water flows from the passage at the lower end of the partition wall 3 toward the partition wall 7, but since the area of the passage is narrowed by the partition wall 3 and becomes small, the inflow speed of this drainage water becomes faster, and the higher the specific gravity, the faster the acceleration. Because of this, the waste water is separated into water with a high specific gravity and grease with a low specific gravity before colliding with the partition wall 7, and the separated water with a high velocity collides with the partition wall 7 first, causing the tongue piece 7
₁ , the slow-moving grease is rapidly pushed up to the water surface by the buoyant force due to the difference in specific gravity and this water flow, and only the water reaches the partition wall 7.
passes through the opening 7 ₂ and flows in the direction of the partition wall 4,
It enters the discharge chamber 6 from the lower end passage of the partition wall 4, and the discharge port 2
₁ and is ejected from the box. Drainage water is stored in the box while maintaining a constant water level, but the above action is repeated every time wastewater is introduced into the intake chamber 5, and oils such as grease that should not be discharged are collected. It is.

As described above, the grease collector according to the present invention separates water and oil in waste water by utilizing not only the difference in buoyancy due to the difference in specific gravity, but also the difference in acceleration. From then on, as usual,
Sufficient collection efficiency can be obtained without using a large number of partition walls, and the number of partition walls can be minimized, reducing material and processing costs. It is easy to perform and has great practical effects.
