Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray painting wastewater, specifically a spray painting wastewater filtration device. Background Technology
[0002] The spray painting wastewater filtration device is a device that can intercept large solid impurities such as paint residue, pigment particles, and metal shavings in wastewater, and can use filter media to intercept mechanical impurities larger than a certain pore size.
[0003] The announcement number is CN218608254U, relating to the field of spray painting wastewater treatment technology, specifically a spray painting wastewater filtration device. The device includes a protective box, with a motor mounted at the top. The motor's output shaft is connected to a drive shaft, and multiple actuating plates are connected to the outer circumference of the drive shaft. An inlet pipe connects to the upper part of the protective box. In modern industrial production, spray painting is widely used in automobile manufacturing, furniture production, and machining, among many other fields. However, the spray painting process generates a large amount of spray painting wastewater. This wastewater has a complex composition, containing numerous impurities such as paint mist particles, pigments, resins, organic solvents, and various additives. Existing spray painting wastewater filtration devices face many challenges in treating this wastewater. Impurities in the wastewater easily clog the filter screen during the filtration process. On the one hand, solid suspended matter such as paint mist particles and pigments vary in size and easily accumulate on the filter screen surface, gradually forming a filter cake layer over time, hindering the normal passage of wastewater. On the other hand, viscous substances such as resins adhere to the filter screen, not only increasing filtration resistance but also adsorbing other fine impurities, further aggravating filter screen clogging. What's more challenging is that cleaning these clogging impurities during the filtration process is extremely difficult. Most current filtration devices cannot achieve efficient online cleaning during operation and can only be cleaned after use. This leads to a gradual increase in filter screen clogging over a long period of time, resulting in a continuous decrease in filtration speed and severely affecting filtration efficiency.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6The present invention provides a technical solution: a spraying wastewater filtration device, including a housing 1, a filter screen 2 fixedly connected to the lower interior of the housing 1, a rotating mechanism 3 arranged on the upper interior of the housing 1, and a reciprocating mechanism 4 arranged on the upper part of the housing 1.
[0024] The rotating mechanism 3 includes a first rotating shaft 301 disposed inside the upper part of the outer casing 1. Third grooves 302 are provided inside both sides of the first rotating shaft 301. A gear 303 is disposed in the middle of the third grooves 302. A second rotating rod 304 is fixedly connected inside the middle of the gear 303. A fixing plate 317 is provided at one end of the second rotating rod 304 near the center of the first rotating shaft 301. A third rotating shaft 315 is fixedly connected at one end of the second rotating rod 304 near the center of the first rotating shaft 301. A fourth groove 316 is formed inside the fixing plate 317. A stirring plate 305 is fixedly connected to one end of the moving rod 304. A rack 306 is provided on one side of the gear 303. A first guide groove 307 is provided on one side wall of the third groove 302. A second guide groove 308 is connected below the first guide groove 307. A third guide groove 309 is connected below the second guide groove 308. A first guide rod 310 is provided inside the third guide groove 309 and is fixedly connected to the rack 306. The upper and lower ends of the first guide groove 307 and the third guide groove 309 are both inclined straight lines. The upper and lower ends of the guide groove 309 are inclined in opposite directions, and the other ends of the first guide groove 307 and the third guide groove 309 have a vertical straight-line appearance. This allows the first guide rod 310 to move laterally when it moves at the upper and lower ends of the first guide groove 307 and the third guide groove 309, but it will not move laterally when it moves inside the other ends of the first guide groove 307 and the third guide groove 309. A first groove 311 is provided at the connection between the first guide groove 307 and the second guide groove 308. The inner part of the first groove 311... An elastic rubber pad 312 is fixedly connected to the side, and a baffle 313 is fixedly connected to one end of the elastic rubber pad 312. The appearance structure of the second guide groove 308 is a vertical straight line, and the second guide groove 308 and the first guide rod 310 are fitted with a clearance fit, so that the first guide rod 310 will not move laterally when it moves inside the second guide groove 308. The side of the baffle 313 near the gear 303 is an inclined surface, so that the first guide rod 310 can push the baffle 313 along the inclined side of the baffle 313 to move to the inside of the first groove 311.
[0025] The reciprocating mechanism 4 includes a motor 401 fixedly connected to the upper part of the outer casing 1. The output end of the motor 401 is fixedly connected to a second rotating shaft 402. A second groove 403 is formed inside the center of the first rotating shaft 301. The second rotating shaft 402 is nested inside the second groove 403. A fourth guide groove 404 is formed on the upper inner wall of the outer casing 1. A third guide rod 405 is fixedly connected to the first rotating shaft 301 in the fourth guide groove 404. The inner side of the second groove 403 fits against the outer side of the second rotating shaft 402. The second rotating shaft 402 has a cuboid shape, so that the second rotating shaft 402 will not rotate when it moves inside the second groove 403. The fourth guide groove 404 is composed of multiple connected "V"-shaped grooves, so that the third guide rod 405 will reciprocate up and down when it moves inside the fourth guide groove 404. A rotating disk 406 is fixedly connected to the upper end of the second rotating shaft 402. The rotating disk 406 is connected to the rack 306 by a sliding connection.
[0026] When filter screen 2 filters the spraying wastewater, motor 401 is started to drive the second rotating shaft 402 to rotate, causing the first rotating shaft 301 and the third guide rod 405 to rotate. Because the fourth guide groove 404 is composed of multiple interconnected "V"-shaped grooves, the inner side of the second groove 403 is in contact with the outer side of the second rotating shaft 402, and the second rotating shaft 402 has a cuboid shape, driving the first rotating shaft 301 to rotate and reciprocate up and down. When the first rotating shaft 301 is at its lowest point, the first guide rod 310 is at its highest point in the first guide groove 307, and the rack 306 is in a meshing state with the gear 303. When the first rotating shaft 301 moves upward, the gear 303, the third rotating shaft 315, and the second rotating rod 304 move, causing the stirring plate 305 to become horizontal. After the agitator plate 305 becomes horizontal, the second rotating rod 304 moves to the middle end of the fourth groove 316, and the first guide rod 310 moves from the side of the first guide groove 307 near the first rotating shaft 301 to the lower end of the first guide groove 307. Because the rotating disk 406 and the rack 306 are connected by a sliding connection, the rack 306 moves to the side away from the gear 303, causing the agitator plate 305 to move upward horizontally, driving water and impurities upward. When the agitator plate 305 moves to the top, the first guide rod 310 moves to the bottom of the second guide groove 308. Similarly, when the agitator plate 305 moves downward, it becomes vertical, reducing the amount of impurities that need to be pushed. In summary, this reduces the accumulation of impurities and improves filtration efficiency during filtration by the filter screen 2.
