Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment devices, and in particular to an environmentally friendly sewage treatment device for a paint spraying room. Background Art

[0002] A spray paint room, as the name implies, is a room where the filtered spray paint objects are sprayed and colored. It is also called a paint room. The spray paint room is a device that provides a special environment for painting operations. It can meet the requirements of temperature, humidity, light intensity, air cleanliness, etc. for painting operations. It can limit and treat the paint mist and organic waste gas generated during the spray painting operation and then discharge them. It is an environmentally friendly painting equipment. However, when spraying paint, a large amount of wastewater containing paint will be generated in the spray paint room. Therefore, it is generally equipped with a flotation machine for recycling and treatment. The flotation machine is a dissolved air system that produces a large number of fine bubbles in the water, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The buoyancy principle is used to make it float on the water surface, thereby realizing the water treatment equipment of solid-liquid separation. In addition, the flotation machine does not need to add chemical agents during the treatment process, avoiding secondary pollution, and the energy consumption is relatively low, making the use of the flotation machine very environmentally friendly.

[0003] It should be noted that when the flotation machine is in use, air is released into the sewage through the air dissolving pump and the release head, thereby generating a large number of bubbles, so that the waste residue in the sewage is concentrated on the surface of the sewage, and the scraper frame drives the scraper plate to scrape the waste residue onto the slag discharge plate for recovery; during the use of the flotation machine, since the sewage contains more impurities and the release head is easily blocked during the long-term use of the flotation machine, the release head cannot form enough bubbles to treat the sewage, resulting in poor sewage treatment effect; in addition, during the scraping process of the scraper plate, since the waste residue is very easy to condense on the surface of the scraper plate, but it is not treated in time, the waste residue condenses more and more, which not only easily causes the waste residue to deteriorate and cause new pollution, but also the waste residue condenses on the scraper plate, making it impossible for the scraper plate to effectively scrape off the waste residue, resulting in poor treatment effect of the flotation machine.

It should be noted that in the embodiment of the present invention, when the waste slag is pushed onto the slag plate 2, the slag plate 2 is rotated by force and squeezes the support wheel 904, and then the support wheel 904 moves in the support seat 902 through the support rod 903, and squeezes the lifting spring 905 to retract. After the sewage of the waste slag is filtered out, the support wheel 904 is driven to reset through the support rod 903 under the rebound force of the lifting spring 905, and the slag plate 2 is reset, which is convenient for slag discharge.

[0037] For further information, please refer to the attached manual. Figure 1-2 , an environmentally friendly paint spray room sewage treatment device provided by an embodiment of the present invention, a return pipe 12 is installed on the air flotation machine body 1, and the return pipe 12 recycles the water filtered out of the waste residue; In addition, a slag hopper 11 is installed on the air flotation machine body 1, and the slag hopper 11 is used to discharge the waste slag. It should be noted that in the embodiment of the present invention, the waste slag is discharged through the slag hopper 11, and the water filtered out of the waste slag is discharged and recycled through the return pipe 12.

[0038] In summary, the working principle of an environmentally friendly paint spray room sewage treatment device provided by an embodiment of the present invention is: When the release head 5 is blocked and the air cannot be released, the air pressure in the switch box 702 increases, which in turn squeezes the push plate 706 downward. The push plate 706 moves on the bottom side of the switch box 702 through the push rod 707, which squeezes and retracts the two wedge-shaped card plates 710. The wedge-shaped card plates 710 move in the telescopic groove 709 and drive the return spring 711 to retract under force until the push plate 706 moves to the bottom of the switch tube 703. At this time, the wedge-shaped card plate 710 moves to the outside of the switch box 702 and, under the rebound force of the return spring 711, The wedge-shaped card plate 710 is driven to be stuck outside the switching box 702, and then the position of the push plate 706 is fixed. At this time, the high-pressure gas enters the spare release head 701 through the switching tube 703. At the same time, the push rod 707 moves to drive the synchronous frame 716 to move. The synchronous frame 716 drives the opening and closing rotating rod 713 to rotate through the adapter shaft 715. The opening and closing rotating rod 713 drives the isolation cover 705 to rotate and open through the opening and closing rotating shaft 714, so that the spare release head 701 can be exposed for use, and the air is continuously released into the sewage to ensure the sewage treatment effect; Furthermore, in the process of the scraper frame 10 driving the scraper plate 6 to rotate and scrape the slag, the scraper plate 6 synchronously drives the U-shaped jet box 801 to move. When the U-shaped jet box 801 moves to a position close to the slag discharge plate 2, the extrusion push rod 807 contacts the semicircular frame 808 and is squeezed by the semicircular frame 808, thereby causing the extrusion push rod 807 to retract and drive the return spring 806 to be stressed. The extrusion push rod 807 drives the U-shaped sealing frame 804 to move and drives the return spring 806 to be stressed, so that the multiple connecting holes 805 and The multiple air blowing holes 803 are connected, so that the high-pressure gas blown out by the air pump 802 is blown out through the multiple connecting holes 805 and the multiple air blowing holes 803, so as to blow away the waste residue adhered to the scraper plate 6 and discharge it onto the slag discharge plate 2. With the continuous rotation of the scraper frame 10, the extrusion push rod 807 is separated from the semicircular frame 808, and the U-shaped sealing frame 804 is reset under the rebound force of the reset spring 806, so that when the scraper plate 6 is away from the slag discharge plate 2, the blowing can be stopped to avoid affecting the scraping residue. Furthermore, when the scraper plate 6 scrapes the waste slag onto the slag discharge plate 2, the slag discharge plate 2 is forced to rotate due to the large amount of sewage, and squeezes the support wheel 904. The support wheel 904 drives the support rod 903 to move in the support seat 902, and drives the lifting spring 905 to retract. At the same time, the rotation of the slag discharge plate 2 synchronously drives the rotating filter plate 901 to rotate, so that the rotating filter plate 901 is separated from the positioning shaft 909. Under the torsional force of the rotary torsion spring 907, the rotating filter plate 901 is driven to rotate to form an angle with the slag discharge plate 2, that is, The waste residue can be blocked and the sewage in the waste residue can be filtered at the same time; after the filtration is completed, the weight of the waste residue decreases, and under the lifting force of the lifting spring 905, the support rod 903 drives the support wheel 904 to reset. At this time, the rotating filter plate 901 is blocked by the positioning shaft 909, so that the rotating filter plate 901 is flattened, and then the waste residue can enter the residue discharge hopper 11, and the filtered sewage is discharged and recovered through the return pipe 12. At the same time, the rotating filter plate 901 is flattened to squeeze the switch 910, so that the warning light 911 is turned on.
