In order that those skilled in the art will better understand the technical solutions of the present invention, the following description of the preferred embodiments of the present invention is provided in conjunction with specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.
The present invention will be further described with reference to the following examples and figures 1-5, but the invention is not limited thereto.
The invention provides a two-stage circulating type oil stain reducing system which is suitable for municipal oil separating facilities, does not need electricity, and is energy-saving and environment-friendly.
The first embodiment is as follows:
as shown in fig. 1 to 5, oily wastewater enters an oil drainage pool 1 through a water inlet pipe 3, waste impurities are retained on a slag blocking net 6, oil stains are retained on a first water-permeable oil-separating layer 11, the water level is lower at the moment, a liquid level automatic control valve 12 is closed, and due to different oil-water densities, the fixed height of the first water-permeable oil-separating layer 11 is three-side higher, one side is lower, the oil stains are intercepted and overflowed into an oil drainage pipe 5 on the lower side, and then enter an oil collection pool 2 through the oil drainage pipe 5; the water in the oil collecting pool is filtered by the second water-permeable oil-separating layer 20 and then flows back to the oil discharging pool 1 through the filter liquid return pipe 14, the filter liquid return pipe 14 is provided with a check valve, and the water can only flow from the oil collecting pool 2 to the oil discharging pool 1.
In this embodiment, when the water content of the sewage is less, the oil contamination can be isolated by lifting the first water-permeable oil-separating layer 11 in the oil collecting tank 2. Along with the continuous rising of water level, greasy dirt overflows from the oil extraction pipe and enters the oil collecting tank, after the greasy dirt overflows, along with the continuous rising of water level, the liquid level automatic control valve 12 rises along with the water level, the liquid level automatic control valve 12 is automatically opened, and sewage flows to the municipal pipe network from the water outlet pipe 4 along with the water pressure.
In this embodiment, the liquid level automatic control valve 12 at least comprises a floating member 17, a screw rod 16 and a plug 18, wherein the floating member 17 is made of wood plug or hollow cylindrical plastic, and when the water level is low, the valve is closed; as the water level rises, the buoyancy and the water pressure rise, and the valve opens water to flow out of the pipeline; the valve is convenient to open and close.
In this embodiment, the last rigid coupling of sediment block net 6 has 4 second couples 7, and each second couple 7 all hangs in the cell body through chain 19, when needs clear away the residue on sediment block net 6, takes out sediment block net 6 through chain 19 and clears up.
In this embodiment, the oil drain pipe 5 is lower than the water inlet pipe 3 and is not limited to 0.4 m; outlet pipe 4 is less than inlet tube 3 and is not limited to 1m, and the pond internal water of being convenient for flows out, and later stage fortune dimension.
In this embodiment, the filtrate return pipe 14 is provided with a check valve thereon, and penetrates out of the oil collecting tank 2 through the bottom of the oil collecting tank 1.
In this embodiment, the first water-permeable oil-separating layer 11 and the second water-permeable oil-separating layer 20 both use oil-separating cotton.
In this embodiment, the top of the oil drainage pool 1 and the top of the oil collection pool 2 are both covered with a cover plate 13.
Example two:
compared with the first embodiment, the main differences of the present embodiment are: when the weather is cold, when the greasy dirt freezes easily, visual condition sets up the heat preservation baffle in 19 tops of chain, if weather is too cold, first permeating water in the oil extraction pond 1 and separating oil layer 11 oil dirt and freezing, unable overflow this moment, accessible chain 19 drags first permeating water and separates first couple 15 on the oil layer 11, moves along guide rail 8, and it is regional not to block sediment net 6 to reach the top, upwards carries out through chain 19 and first couple 15 and empties the greasy dirt.
In this embodiment, the first water-permeable oil-separating layer 11 is fixed by the first hook 15, and has four hooks, one of which is lower and inclined, and the oil stain overflows to the oil collecting tank 2 through a lower point. Two ends of the guide rail 8 are provided with grooves 9 for fixing the first hook 15.
The implementation of the invention has the advantages that: the invention provides a conveniently-cleaned oil drainage pool, which utilizes the height difference of a water outlet pipe and an oil drainage pipe and water and oil filtering and separating cotton to isolate oil stains, sewage seeps downwards, the oil stains overflow into an oil collection pool through the lowest point of the water and oil filtering and separating cotton, the oil stains can be stored, manual operation can clean the oil stains from long-term cleaning to interval time periods, and the labor cost is reduced. And is convenient for cleaning; the oil filtering and oil separating cotton separates oil stains to guide the oil stains to overflow to the oil collecting pool, and redundant water in the oil collecting pool flows back to the oil drainage pool. And the water and oil filtering cotton is matched with the hook guide rail, so that the water and oil filtering cotton can conveniently slide to an area without a slag blocking net above the water and oil filtering cotton, and can be conveniently lifted out for cleaning. It can be used in hot or cold weather.
Wherein, the switch that the liquid level control valve passes through water level automatic control valve passes through the decline automatic start-stop of water level rising, need not the power consumption, through liquid level automatic control, in the oil drainage pond, can wait the greasy dirt overflow to go out, along with the water level continues to rise, the valve is reopened, more traditional overflow does not have the mode of valve, traditional oil interceptor, pond ponding is more, the staff is inconvenient down in the pond, this valve installation back, the outlet pipe can be located lowerly, also can reach the floated purpose of greasy dirt overflow, and after reacing a take the altitude, the water level can effectual decline discharge.
Wherein, block the great debris of sediment net effective interception, prevent that the pipe network from blockking up.
Wherein, the top of the residue blocking net and the water and oil filtering cotton is provided with a chain, which is convenient for lifting and cleaning without the operation of going into the pond.
According to the description and the drawings, the two-stage circulation type oil pollution reducing system can be easily manufactured or used by a person skilled in the art, and the positive effects recorded in the invention can be generated.
