Specifically, the invention works in cooperation with the recovery tank 7, and the recovery tank 7 is specially used for accommodating waste liquid, wherein waste oil and fine slag are mixed in the waste liquid. When the waste liquid is fed into the recovery tank 7, after a certain time, the waste liquid is precipitated, and the mixed slag with a large volume is separated from the waste liquid, wherein the precipitate 71 with a large weight is precipitated at the bottom of the tank, and the float 72 with a small weight floats on the surface of the waste liquid.
When the invention works, waste liquid between the sediment 71 and the floating matters 72 is directly extracted from the recovery tank 7, the waste liquid firstly enters the oil stain separation unit 2, the waste oil is conveyed into the waste oil recovery container 8 after the waste liquid and the waste oil are separated by the oil stain separation unit 2, the waste liquid from which the waste oil is separated is conveyed into the fine slag treatment unit 3, the fine slag which cannot be precipitated or float in the waste liquid is treated by the fine slag treatment unit 3, and finally the waste liquid is conveyed into the proportioning unit 4 to be matched and mixed with corresponding medicaments, and the waste liquid after proportioning and mixing can be reused as recovered water. The invention has compact structure, can integrally complete the oil stain separation, fine slag treatment and proportioning action of waste liquid, thereby improving the efficiency, reducing the space requirement and being beneficial to popularization and use.
Specifically, the chemical agent described in this example is a chemical agent commonly used for wastewater treatment such as a release agent.
In this embodiment, the oil stain separation unit 2 includes a negative pressure extraction mechanism 5 and an oil stain separation structure 6, the negative pressure extraction mechanism 5 is externally connected with a recovery tank 7, and the negative pressure extraction mechanism 5 is used for sucking the waste liquid in the recovery tank 7 into the oil stain separation structure 6; the oil stain separating structure 6 is used for separating oil stains from waste liquid, transmitting separated oil to an external waste oil barrel, and returning separated liquid into the recovery tank 7.
Specifically, the negative pressure extraction mechanism 5 includes an extraction box 51, a one-way valve 52 and a partition plate 53, a negative pressure interface 54 for externally connecting a negative pressure air source is provided at the top of the extraction box 51, the one-way valve 52 is provided at one side of the extraction box 51, a water inlet 510 for communicating with an external recovery tank 7 is further provided at a side of the extraction box 51, the partition plate 53 is provided in the extraction box 51, the partition plate 53 is located above the water inlet 510, and a vent hole 55 for allowing negative pressure air to circulate is provided between the partition plate 53 and the negative pressure interface 54; the vent hole 55 and the negative pressure interface 54 are arranged in a staggered manner.
The water inlet 510 is communicated with the recovery tank 7, preferably, the water inlet 510 contacts with the recovery tank 7 through a pipe, and the water inlet 510 and the liquid level of the recovery tank 7 are not at the same height; and the check valve 52 is communicated with the outside oil stain separating structure 6. When the invention works, the check valve 52 is in a closed state, and the interior of the extraction box 51 is in a negative pressure state by the operation of a negative pressure air source, so that waste liquid is sucked into the interior of the extraction box 51 through the water inlet 510 by negative pressure; after a certain amount of waste liquid is sucked, the negative pressure air source stops acting, then the one-way valve 52 is opened, and the waste liquid flows into the oil stain separating structure 6 from the one-way valve 52, so that the extraction effect is achieved.
The invention can realize the effect that the waste liquid quantitatively extracted each time enters the oil stain separating structure 6, can avoid pollution caused by the contact of the waste liquid and the extracted power structure, prolongs the service life, and ensures that the extraction is more stable.
In this embodiment, the water inlet 510 is disposed on a side of the suction box 51 away from the check valve 52, and the partition 53 is disposed on the same side of the suction box 51 as the water inlet 510. That is, when the interior of the extraction box 51 is extracted to a negative pressure state, the waste liquid enters the extraction box 51 from the water inlet 510, and at this time, the waste liquid is prevented from being sputtered into the negative pressure interface 54 due to the blocking of the partition plate 53, so that the effect of protecting the negative pressure air source is achieved. Specifically, the negative pressure port 54 is located directly above the partition 53, that is, the effect of reliably separating the negative pressure port 54 from the water inlet 510 by the partition 53 is achieved.
In this embodiment, the bottom of the extraction tank 51 gradually decreases in height from one end near the water inlet 510 to one end near the check valve 52.
In practical use, the height of the check valve 52 is lower than that of the water inlet 510, so that when the check valve 52 is opened, the waste liquid can flow to the check valve 52 automatically under the action of gravity, so as to ensure the reliability of outputting the waste liquid output by the invention, ensure that the waste liquid can be completely emptied, and avoid the influence on the treatment efficiency caused by the retention of the waste liquid in the extraction tank 51.
In this embodiment, the extraction box 51 includes a bottom case 56 and a top case 57, the bottom case 56 is welded to the top case 57, the check valve 52 is disposed on the bottom case 56, and the water inlet 510 is disposed on the top case 57. The bottom shell 56 and the top shell 57 are respectively formed by bending two sheet metal parts, so that the manufacturing of the extraction box 51 is simpler, namely the cost of the extraction box is reduced, and the extraction box is favorable for popularization.
In this embodiment, the negative pressure pipe 58 is welded to the negative pressure port 54, and the water inlet pipe 59 is welded to the water inlet 510. Through the arrangement of the negative pressure pipe 58 and the water inlet pipe 59, the invention is more convenient to connect with a waste liquid treatment structure and a negative pressure air source, can ensure that no leakage occurs after connection, and improves the stability and the safety of work.

Specifically, the oil stain separating structure 6 includes a filtering mechanism 61 and a separating mechanism 62, the filtering mechanism 61 is used for filtering oil in the waste liquid, and the separating mechanism 62 is used for separating water and oil from the separated waste liquid and outputting the separated waste liquid to the outside; the filtering mechanism 61 comprises a filtering container 63 and an excessive container 64, the excessive container 64 is positioned between the filtering container 63 and the separating mechanism 62, a plurality of filtering holes 631 are arranged at the bottom of the filtering container 63, and the waste liquid enters the excessive container 64 after being filtered by the filtering holes 631; the bottom of the excess container 64 is provided with a transfer port 641, and the transfer port 641 is used for transferring the waste liquid from the excess container 64 to the separation mechanism 62.
During operation, the waste water is pumped into the filter container 63 through the negative pressure pumping mechanism, and enters the excessive container 64 through the filter holes 631 under the action of gravity, and when the waste water passes through the filter container 63, solid impurities in the waste water are blocked in the filter container 63, so that the filtering effect is achieved; after the wastewater enters the filtering container 63, the wastewater falls into the separating mechanism 62 through the transmission port 641, and layering occurs in the separating mechanism 62 due to the fact that the density of the oil stain is lower than that of the water, so that the oil stain separating effect is achieved.
In this embodiment, the filter container 63 is mounted on the top of one side of the excessive container 64, and the transfer port 641 is positioned on the bottom of the other side of the excessive container 64; the bottom of the transition receptacle 64 gradually decreases in height from side to side.
