Abstract
The utility model provides a rolling oil recovery device of negative pressure suction formula, including connecting the connector in triple -valve body, adapter sleeve and recovery pipeline, the tapering point of connector is twisted in adapter sleeve's the tapered runner through its surperficial screw thread, so that toper pipeline and adapter sleeve's in the connector tapered runner feeds through and forms the venturi tube, like this when rolling oil stream is gone into wherein, the flow has that a follow greatly sharply diminishes and the process of grow, and then form the negative pressuren zone at the position of both butt joints, and then use the recovery pipeline to be connected this negative pressuren zone and pit, thereby realized utilizing the negative pressure to come real -time extraction and retrieved the rolling oil in the pit, the utility model discloses continuously retrieve the rolling oil in the pit in can putting into production, unload the long -pending oil in roll pit on having significantly reduced, effectively avoid rolling oil extravagant, reduced manufacturing cost.
Description
Technical field
This utility model relates to the ROLLING OIL of cold-rolling mill and reclaims field, a kind of negative pressure suction type recovering device for rolling oil.
Background technology
At present, existing cold-rolling mill is in the operation of rolling, and part ROLLING OIL can flow into band and unload in volume melt pit, and accumulates in the waste wherein causing ROLLING OIL.In order to make full use of the ROLLING OIL in melt pit, the general mode using pumping, if but by pumping, long-pending oil in melt pit needs to reach certain degree of depth could use pumping, this is accomplished by accumulating for a long time, but ROLLING OIL such as accumulates overlong time, can be contaminated and may go bad, which adds ROLLING OIL meaningless consumption in process of production, cause production cost to raise.
Utility model content
ROLLING OIL for solving in prior art in melt pit can not clear up the problem that the waste caused is serious and then increases production cost in time, this utility model provides a kind of negative pressure suction type recovering device for rolling oil, this device utilizes negative pressure produced by venturi principle to the ROLLING OIL drawing in melt pit, achieve and clear up the ROLLING OIL in melt pit in time, the contamination and deterioration problem preventing ROLLING OIL to cause in accumulating in melt pit for a long time, reduces production cost.
nullThe technical scheme that this utility model is used by the above-mentioned technical problem of solution is: a kind of negative pressure suction type recovering device for rolling oil，ROLLING OIL is delivered to spray beam by oil feed line and cools down roll by centrifugal pump one end，The other end is back to milling train oil trap by unloading line，Described retracting device includes that inside has the union joint of taper pipeline、Triple-valve body、Inside has connection sleeve pipe and the recovery pipe of tapered runner，Wherein，One end of union joint is that surface has threaded taper，And be threadedly secured in a through hole of triple-valve body，The other end connects unloading line end，The one end connecting sleeve pipe is threaded in another through hole of triple-valve body，The other end is connected with the oil pumping pipeline extending in milling train oil trap by branch sleeve，And the tapering point of union joint being threaded in the tapered runner connecting sleeve pipe by its surface，So that taper pipeline connects with tapered runner and forms Venturi tube，Described recovery pipe is fixed in last through hole of triple-valve body by a fixing plug，And recovery pipe and taper pipeline connection，With constituted by taper pipeline and tapered runner in ROLLING OIL Venturi tube time，Produce negative-pressure sucking in recovery pipe and reclaim the ROLLING OIL in melt pit.
The end of described recovery pipe has been threaded connection extension, and the length being screwed in recovery pipe by regulation extension adjusts the total length of recovery pipe and extension.
One end that described connection sleeve pipe is connected with triple-valve body is provided with annular retaining ring.
Beneficial effect: this utility model is assembled by triple-valve body by the union joint and the internal connection sleeve pipe with tapered runner that inside has taper pipeline, define Venturi tube, so when ROLLING OIL flows into wherein, flow has one from drastically diminishing greatly and becoming big process, and then form negative pressuren zone at the position of both docking, then re-use recovery pipe to be connected with melt pit by this negative pressuren zone, it is achieved thereby that utilize negative pressure to extract the ROLLING OIL reclaimed in melt pit in real time；ROLLING OIL in melt pit can persistently be reclaimed by this utility model aborning, greatly reduces the long-pending oil unloaded in volume melt pit, is prevented effectively from ROLLING OIL waste, reduces production cost.

Detailed description of the invention
nullAs shown in the figure，A kind of negative pressure suction type recovering device for rolling oil，ROLLING OIL is delivered to spray beam 3 by oil feed line 2 and cools down roll by centrifugal pump 1 one end，The other end is back to milling train oil trap 11 by unloading line 4，Described retracting device includes that inside has the union joint 6 of taper pipeline 5、Triple-valve body 7、Inside has connection sleeve pipe 8 and the recovery pipe 16 of tapered runner 9，Wherein，One end of union joint 6 is that surface has threaded taper，And be threadedly secured in a through hole of triple-valve body 7，The other end connects unloading line 4 end，The one end connecting sleeve pipe 8 is threaded in another through hole of triple-valve body 7，The other end is connected with the oil pumping pipeline 10 extending in milling train oil trap 11 by branch sleeve 14，And the tapering point of union joint 6 being threaded in the tapered runner 9 connecting sleeve pipe 8 by its surface，So that taper pipeline 5 connects with tapered runner 9 and forms Venturi tube，Described recovery pipe 16 is fixed in last through hole of triple-valve body 7 by a fixing plug 15，And recovery pipe 16 connects with taper pipeline 5，With constituted by taper pipeline 5 and tapered runner 9 in ROLLING OIL Venturi tube time，Produce negative-pressure sucking in recovery pipe 16 and reclaim the ROLLING OIL in melt pit 12.
It is more than basic embodiment of the present utility model, can further be improved, optimize and limit on the basis of above:
As, the end of described recovery pipe 16 has been threaded connection extension 13, and the length being screwed in recovery pipe 16 by regulation extension 13 adjusts recovery pipe 16 and the total length of extension 13, thus adapts to the melt pit 12 of different depth；
And for example, one end that described connection sleeve pipe 8 is connected with triple-valve body 7 is provided with annular retaining ring 801, limits connection sleeve pipe 8 by annular retaining ring 801 and union joint 6 is screwed into the position in triple-valve body 7.
