Description

Lifting type outer cover device of oil-water separator

Technical Field

The invention relates to an oil-water separator, in particular to a lifting type outer cover device of the oil-water separator.

Background

A conventional centrifugal oil-water separator (taiwan patent No. I586417) includes a rotation unit, a water guide plate, a cylinder unit, and an oil-water separation unit. The rotating unit comprises an oil-water injection pipe and a driving shaft. The water guide disc is sleeved on the rotating unit. The barrel unit comprises an inner barrel, a middle barrel and an outer barrel. The inner cylinder is provided with an oil spilling hole adjacent to the rotating unit, the middle cylinder is provided with an oil discharge channel arranged at the bottom, and the outer cylinder is provided with a water outlet arranged at the bottom. The oil-water separation unit comprises a main conical disc and a plurality of secondary conical discs positioned at the bottom of the main conical disc.

In the oil-water separation operation, the waste water containing grease can be continuously injected from the main oil-water injection port and guided to an oil-water separation space of the inner cylinder. And when the driving shaft of the rotating unit is driven by power and drives the inner cylinder and the oil-water separation unit to rotate, the grease-containing wastewater in the oil-water separation space is close to and collected towards the rotating unit due to the centrifugal force, and the wastewater with heavier specific gravity is close to and collected towards an inner annular wall of the inner cylinder. Then, the grease and waste water which have been Phase separated (Phase Separation) are pushed by the grease-containing waste water continuously supplemented from the oil-water injection pipe, so that the waste water at the periphery naturally flows through the top surface of the main conical disc, and finally is discharged through the water outlet with the opening direction facing downwards.

The grease on the inner periphery will naturally also pass down through the oil spilling hole and finally be discharged through the oil discharging channel.

Although such a separate oil-water separator has been used for its intended purpose. However, when the oil-water separator is to be cleaned, the operator needs to disassemble or assemble the components such as the top wall of the outer cylinder, the water guide plate, the oil-water injection pipe, etc., and the number of screws needs to be removed, and when the top wall of the outer cylinder is disassembled from the top of the outer cylinder, because the top wall of the outer cylinder has no force application point or stable positioning point, when the outer cylinder is taken, the top wall of the outer cylinder is easy to slip and drop from the hand, or the top wall of the outer cylinder is easy to shake when placed, and the components such as the inner water guide plate, the oil-water injection pipe, etc. are easy to drop and lose, which causes the trouble of cleaning operation.

As shown in fig. 3 to 7, when the oil-water separator 2 is installed and the outer cover device 100 of the present invention is also installed and positioned on the frame 1 and covers the oil-water separator 2, the base 22 of the cover unit 20 is set to be located on the mounting seat 102 and located at a covering position. When the cover unit 20 is in the closed position, the first extending path 32 is communicated with the waste liquid inlet 208 through the upper concave hole 342 and the inner hole 371, and the second extending path 33 is communicated with the water outlet 209 through the lower concave hole 343. At this time, the male screw 374 of the through pipe 37 is screwed to the female screw 208' of the waste liquid inlet 208, and the through pipe 37 and the waste liquid inlet 208 are reliably connected.

During oil-water separation, the wastewater containing oil can be continuously introduced into the wastewater introduction channel 13 from the introduction section 131, and enters the upper concave hole 342 through the first extension channel 32, and sequentially flows through the through hole 373 and the inner hole 371 to enter the waste liquid inlet 208, and the wastewater containing oil is guided to the oil-water separation space 203. When the driving shaft 202 is driven by power and drives the cylinder 204, the first conical disk 205, the second conical disk 206 and the diversion conical disk 207 to rotate together, the grease-containing wastewater in the oil-water separation space 203 is collected toward the driving shaft 202 by centrifugal force, and the wastewater with a heavier specific gravity is collected toward the cylinder 204. Then, the grease and waste water that have been separated are pushed by the grease-containing waste water continuously replenished from the waste water inlet 208, so that the waste water at the periphery flows upwards along the gap between the first conical disk 205 and the barrel 204 until entering the lower recess 343, along the second extending channel 33, the drainage channel 14, and finally discharged through the discharge section 142.

When the oil-water separator is to be cleaned, the operator first rotates the knob 38 and disengages the external threaded portion 374 of the through pipe 37 from the internal threaded portion 208' of the waste liquid inlet 208, and when the operator pulls the knob 38, the cantilever 12 can rotate relative to the pivot base 11 and the cover unit 20 and the connecting unit 30 are driven to change from the covering position shown in fig. 3 and 4 to the opening position (see fig. 9) which keeps the base 22 away from the mounting base 102.

When the cover unit 20 is in the opened position, the through pipe 37 (the first extending channel 32) is far away from the waste inlet 208, and the lower concave hole 343 (the second extending channel 33) is also far away from the drain 209.

Therefore, the present invention utilizes the combination of the pivot unit 10 of the housing device 100, the cover unit 20 and the connection unit 30, the cover unit 20 can be switched between the covering position and the uncovering position with respect to the rack 1, and when the cover unit 20 is in the uncovering position, the cover unit 20 and the connection unit 30 are positioned with respect to the pivot unit 10, the components of the cover unit 20 and the connection unit 30 will not fall out or be lost, the operation of the operator is labor-saving, and the cleaning operation is more facilitated.

In summary, the lift-type cover device of the oil-water separator of the present invention has the advantages of simple structure, easy operation, and reliable achievement of the object of the present invention.
