Technical Field

The invention relates to the field of oil-water separation, in particular to an oil-water separator.

Background

In the use of lathe, can avoid producing the water oil mixture, for the environmental protection, also for retrieving fluid, need separate the water oil mixture, the water oil separator who generally uses in the current industry is called belt oil separator (belt formula or guipure formula), the adsorption band that will have stronger adsorption grease ability during the use invades liquid in with fluid adsorption band goes out, the adsorption band extrudes the separation that realizes profit again, this type of water oil separator's mounted position can only be placed on the liquid case, need occupy certain water tank space, especially when the liquid case is less, water oil separator can extrude the space that accounts for other part, cause the installation space nervous, the space also leads to the later maintenance very narrow and small inconvenient. Meanwhile, the oil-water separator is limited by an installation space and an adsorption band, and the oil removal amount in unit time is very limited. When a plurality of machine tools share one liquid tank, a single oil-water separator cannot meet production requirements, a plurality of oil-water separators need to be placed, and accordingly space occupation and investment of fixed assets are increased.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

Fig. 1-2 are schematic structural diagrams of an oil-water separator according to the present invention. An oil-water separator comprising: the oil collecting device comprises a box body 1, a partition plate 2, an oil collecting box 3 and a separation disc 7;

the box body 1 comprises a cover plate, a bottom plate and side plates; the box body 1 is provided with an oil-water mixed liquid inlet, a purified water outlet and an oil liquid outlet;

the oil-water mixed liquid inlet 10 is arranged at the lower part of one side of the box body 1; the purified water outlet 8 is arranged at the upper part of the other side of the box body 1; the oil outlet 9 is connected into the oil collecting box 3 through a sealed pipeline; the position of the oil collecting box 3 is higher than the position of the purified water outlet 8;

the baffle 2 is arranged in the box body 1 and is positioned between the oil collecting box 3 and the purified water outlet, and a purified water channel for purified water to flow through is arranged between the lower end of the baffle 2 and the bottom plate of the box body 1.

A separation disc 7 is arranged between the oil collecting box 3 and the oil-water mixed liquid inlet, the separation disc 7 is a trapezoidal groove with a narrow upper part and a wide lower part as shown in the figure and an opening at the lower end, the separation disc 7 is arranged on a screw rod 5 in a penetrating way, and the screw rod 5 is fixed in the box body 1. Through setting for the angle of dovetail groove hypotenuse, can effectually slow down the velocity of flow of mixed liquid, guaranteed the stability of whole liquid case upper liquid level to be favorable to the layering of stewing of profit.

When the oil-water mixed liquid passes through the inclined plane of each trapezoidal separation disc, under a certain flow velocity, the oil-water separation can be accelerated at the moment due to different oil-water densities, so that the oil separation efficiency is improved.

Preferably, the number of the separation discs 7 is multiple, the separation discs 7 sequentially penetrate through one screw 5 to form a set of separation assemblies, a separation disc distance d is kept between adjacent separation discs 7 on the screw 5, the separation disc height is h, and d < h, so that, as shown in fig. 3, before a front end liquid level 12 crosses over the separation discs, the separation discs flow from a channel below the liquid level to a next layer of space, as shown in a liquid flow direction 13 in fig. 3, and buffering of oil-water mixed liquid and oil-water separation are realized. The spacing distance between the upper part, the lower part, the left part and the right part of the separation disc 7 can be adjusted according to the flow and the flow velocity of oil liquid, so that the mixed liquid can smoothly pass through the separation disc before the separation disc enters the separation disc. The interval undersize, mixed liquid can not all pass through the separation disc for mixed liquid increases at the finite space internal pressure of entering liquid mouth department, has accelerated the velocity of flow of mixed liquid, has lost the effect that the separation disc slows down the velocity of flow, can produce the gas release phenomenon simultaneously, causes the fluctuation of liquid tank liquid level, is unfavorable for the profit separation of standing. If the spacing between the isolation discs is too large, oil can rapidly pass through the isolation discs, and the isolation effect is invalid.

Preferably, the number of the isolation assemblies is multiple, and the isolation assemblies are sequentially arranged between the oil collecting box 3 and the oil-water mixed liquid inlet.

Preferably, the upper end of the partition board 2 is connected with the cover board in a sealing way; the side edge of the partition plate 2 is hermetically connected with the side plate.

Preferably, a spacer 6 is arranged between adjacent separation discs 7 for keeping a certain gap between adjacent separation discs 7.

The separation discs 7 are of a long-strip groove shape, so that at least two screws are needed for fixing, and guide plates 4 are further arranged at the top ends of the two screws for fixing the two screws of the same group of separation discs 7.

The division board is arranged above the oil-water mixed liquid inlet, so that the mixed liquid is prevented from directly rising into the top after entering the box body from the inlet, and the mixed liquid is forced to fully rise through the partition board from the bottom.

Fluid gets into the box from the right side after, from the right side to left, from the bottom up, through stopping of multistage isolation subassembly, the velocity of flow has been reduced, again under the difference of oil and water self proportion, the layering gradually, realize oily underwater, the baffle is only equipped with the water purification passageway in the lower extreme, the water purification passageway between baffle and the bottom plate after the event layering slowly rises to being located the water purification export of leftmost, the oil and the water of right side layering, when rising to collection oil box 3 departments, then the oil that is located the upper strata is discharged from the fluid export through collection oil box, realize the separation of oil and water.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
