Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, an oil recovery reinjection water treatment device, including being sharp conical cushion block 1, and be used for fixed tank tower 5 of fixed cushion block 1, fixed mounting has oil leakage fill 3 on cushion block 1, net gape 11 has been seted up respectively to the conical surface of cushion block 1, be provided with a plurality of buffer patches 2 on the conical surface of cushion block 1 respectively, and buffer patch 2 is located the crisscross distribution of conical surface of cushion block 1, be provided with filter screen 4 in the cushion block 1 and be linked together with net gape 11, its cooperation buffer patch 2 is in order to carry out preliminary deceleration and filtration to the reinjection water in the oil leakage fill 3, the reinjection water on the cushion block 1 flows into on the buffering saddle 6 of 5 bottom grafting after the deceleration and carries out secondary deceleration and filtration. Through the buffer plate 2 that sets up on the cushion table 1 to make the crisscross distribution of buffer plate 2 carry out preliminary deceleration, the filter screen 4 of pegging graft carries out preliminary deceleration and filters in the cooperation cushion table 1, carries out secondary deceleration and filters at the buffering saddle 6 of 5 bottoms grafting of fixed tank tower, and it is also convenient and promotion that the effect in pond brings that can subsequent filtration processing and stew many times to filter the deceleration.

As shown in fig. 3, as a further aspect of the present invention, in order to fix the buffer table 1, a plurality of fixing brackets 51 are provided in the fixed box frame 5, and the buffer table 1 is fixedly attached to the fixing brackets 51.

As further shown in fig. 3 and 4, for the first filtration performed by the buffer table 1, a filter slot 12 is provided in the buffer table 1, and the filter slot 12 is communicated with the net opening 11, and the filter net 4 is inserted into the filter slot 12, because the filter net 4 is inserted into the filter slot 12, it can be replaced.

Further, as shown in fig. 3, the buffer tray 6 is subjected to secondary deceleration and filtration, a settling groove 61 is formed below the edge of the buffer tray 1, an oil outlet pipe 63 is formed below the buffer tray 6, and an oil flow hole 62 is formed between the oil outlet pipe 63 and the settling groove 61. The reinjection water that falls from buffering platform 1 directly flows into and deposits recess 61 in, deposits recess 61 and directly carries out the deceleration to the reinjection water of whereabouts to along with the piling up of reinjection water, it flows to oil outlet pipe 63 through flow hole 62, and some heavier impurity can persist in the bottom of depositing recess 61, and oil outlet pipe 63 extends to the bottom of the pool that stews.
