Detailed Description

The present invention will be described in detail below with reference to the drawings, but it should be emphasized that the following embodiments are only exemplary and are not intended to limit the scope and application of the present invention.

Referring to fig. 1 to 2, the utility model relates to a spray paint waste water treatment recycling device, which comprises a reaction tank 1, a slag receiving tank 2 adjacent to the reaction tank 1, a clarification tank 3 positioned on one side of the reaction tank 1, a clean water tank 4 positioned on one side of the clarification tank 3, and a pipeline 5 for conveying waste water.

The painting waste water is conveyed to the reaction tank 1 through a pipeline 5, and pollutants existing in the painting waste water are mainly organic solvents, surfactants and suspended matters.

The pipeline 5 comprises a main pipe 51, a plurality of first secondary pipes 52 connected with the main pipe 51 in an abutting mode, and a plurality of second secondary pipes 53 connected with the main pipe 51 in an abutting mode. The first secondary pipes 52 and the second secondary pipes 53 are equal in number, and the other ends of the first secondary pipes are butted against a waste water tank and a clean water tank of a paint spray booth. The first secondary pipe 52 is butted against the waste water tank of the spray booth and the second secondary pipe 53 is butted against the clean water tank of the spray booth. The first sub-pipe 52 is used in cooperation with the second sub-pipe 53. The main pipe 51 is also connected with a third auxiliary pipe 54 in a butt joint mode, and the third auxiliary pipe 54 is connected with the reaction tank 1 in a butt joint mode. The wastewater from the paint spray booth is transferred to the reaction tank 1 through the first sub pipe 52, the main pipe 51, and the third sub pipe 54.

The utility model discloses the waste water treatment retrieval and utilization device that sprays paint still has high-pressure positive blower 10, and high-pressure positive blower 10 aims at the bottom of reaction tank 1, provides super large wind-force to reaction tank 1, makes the waste water in the reaction tank 1 roll.

To remove the pollutants better, a manual chemical-adding air flotation process (which is a very common treatment process in the prior art) is adopted, a flocculating agent is added into the wastewater, and cotton-wool-packed flocs are formed in the water and can adsorb various ions and various suspended matters dissolved in the water. The flocs are mutually attracted to form large flocs, and the flocs and bubbles released by the gas-dissolved water act together to pay out the water surface.

The utility model discloses paint spraying wastewater treatment retrieval and utilization device still has the sediment device 6 of scraping of installing in reaction tank 1 top, scrape the sediment device 6 including being fixed in the motor 61 on the reaction tank 1, be fixed in 1 chain conveying mechanism (not instructing) of reaction tank, chain conveying mechanism is including being fixed in a plurality of fixing bases 62 on the reaction tank 1, a pair of roller bearing 63 through bearing (not shown) swing joint fixing base 62, be fixed in the sprocket 64 of roller bearing 63 respectively, connect the chain 65 on the sprocket 64, connect the conveyor belt 66 of motor 61 and roller bearing 63, install in the scraper blade 67 on chain 65 surface. The scraper 67 extends downward into the reaction tank 1.

The motor 61 drives one roller 63 to rotate, the roller 63 drives the other roller 63 to rotate through a chain 65 and a chain wheel 64, the scraper 67 rolls along with the chain 65, and the scraper 67 scrapes bubbles released by flocculating constituents and dissolved gas water from one side of the reaction tank 1 to the other side.

A receiving device 7 is installed on one side of the reaction cell 1, and the receiving device 7 includes a receiving plate 71 located below the conveying mechanism and a guide plate 72 connected to the receiving plate 71. When the flocculating constituent and the air bubbles of the scraper 67 are scraped to the upper side of the receiving plate 71, the scraper 67 continuously pushes the flocculating constituent, the air bubbles and the wastewater in the reaction tank 1 to enter the slag receiving tank 2 through the guide plate 72.

The utility model discloses the waste water treatment retrieval and utilization device that sprays paint still has the pressure filter 9 that docks diaphragm pump 8, connection diaphragm pump 8 in slag bath 2, and the diaphragm pump is the prior art product with the filter, and it is according to the demand, the product that can directly purchase. The filter press applies a certain pressure to the wastewater by using hydraulic pressure, so that clear water is dialyzed. The filter press consists of a filter plate, a filter frame, filter cloth and a squeezing diaphragm.

The diaphragm pump 8 pumps the slag-water mixture in the slag receiving tank 2 into the filter press 9, the filter press 9 separates paint slag from water by squeezing the filter cloth, and the paint slag is changed into mud cakes and left in the filter cloth for periodic cleaning. The clean water seeps out through the micropores of the filter cloth and overflows to the clarification tank 3 after being collected.

The clarifying tank 3 makes the clear water after pressure filtration stay and precipitate, and makes the tiny suspended particles and the clear water fully separated; the precipitated water overflows to the clean water tank 4 through the partition plate.

The utility model discloses paint spraying wastewater treatment retrieval and utilization device still has the feed pump 11 of installing in clean water basin 4, and in 11 one end butt joint clean water basins 4 of feed pump, the other end docks through fourth auxiliary pipe 55 and is responsible for 51. First, second, third, and

fourth valves

502, 503, 504, and 505 are provided between the main pipe 51 and the first, second, third, and

fourth sub pipes

52, 53, 54, and 55, respectively.

When the paint spray booth outputs the wastewater, the fourth valve 505 and the second valve 503 are closed, the first valve 502 and the third valve 504 are opened, and the wastewater flows through the reaction tank 1 through the first auxiliary pipe 52, the main pipe 51 and the third auxiliary pipe 54; when the clean water tank 4 needs to be drained, the fourth valve 505 and the second valve 503 are opened, the first valve 502 and the third valve 504 are closed, and the clean water flows through the fourth secondary pipe 55, the main pipe 51 and the third secondary pipe 54 by the feed pump 11 and flows back to the clean water tank of the air injection chamber. Since some waste water remains in the main pipe 51 when the waste water is discharged, but the amount thereof is very low compared with the amount of the clean water discharged from the clean water tank 4, the waste water in the main pipe 51 is returned to the air blast chamber and then diluted by the clean water, so that the waste water can be reused.

Because the wastewater pool and the clean water pool can store more wastewater and clean water, the wastewater pool can also store the wastewater when the pipeline for conveying the wastewater is stopped; when the clear water conveying pipeline is stopped, the clear water tank can also continuously store clear water, and the overflow phenomenon can not occur.

The wastewater treatment meeting device of the utility model can treat wastewater and then return the wastewater to the air spraying chamber for reuse, and has high use effect; through the mode of sharing the person in charge, can make a round trip to carry the waste water of a plurality of paint spray booth to avoided a paint spray booth to set up the pipeline respectively and brought the cost and rise.

Of course, those skilled in the art should realize that the above-mentioned embodiments are only used for illustrating the present invention, and not for limiting the present invention, and that the changes and modifications to the above-mentioned embodiments are all within the scope of the appended claims as long as they are within the true spirit of the present invention.
