Abstract
Description
Technical Field
[0001] The utility model relates to a pickling acid-drip-proof flushing hook structure, belonging to the technical field of pickling lines. Background Art
[0002] The hook for washing and dripping acid in the existing pickling tank has an upper crossbeam of steel and a lower C-shaped hook, which are connected as a whole by bolts. During the pickling process of the hook carrying the coil, when the conveyor puts the hook carrying the coil into the hydrochloric acid tank, the material reacts chemically with the hydrochloric acid and releases heat, and the airflow causes the acid mist to rise. The acidic water droplets attached to the crossbeam and bolts of the hook body will accumulate and drip onto the coil below. Because the dripping liquid is acidic, it becomes dripping liquid after the coil is dipped in the coating, causing the coil to rust again. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a pickling anti-drip acid flushing hook structure for the above-mentioned prior art, to ensure that there is no dead corner accumulation of acid liquid, to avoid the formation of rust spots on the surface of the material roll, and to ensure the surface quality of the material roll.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a flushing hook structure for pickling and anti-drip acid, including a crossbeam, a C-shaped hook is arranged at the bottom of the crossbeam, the crossbeam and the C-shaped hook are integrated, and a guide unit is arranged at the bottom of the crossbeam, and the outlet of the guide unit is facing the immersion tank; the flushing water flushes the crossbeam, and a large amount of flushed acidic liquid is guided to the immersion tank through the guide unit.
[0005] The guide unit includes a first guide plate and a second guide plate, the first guide plate and the second guide plate are arranged to be tilted downward respectively, and the first guide plate and the second guide plate are tilted in opposite directions, and the high end of the first guide plate is connected to the high end of the second guide plate.
[0006] The first guide plate and the second guide plate are U-shaped structural parts respectively, the U-shaped groove of the first guide plate serves as the first guide groove, and the crossbeam is arranged in the first guide groove and the second guide groove.
[0007] The lower end of the first guide groove and the lower end of the second guide groove are respectively facing the leaching tank
[0008] Compared with the prior art, the utility model has the following advantages: a pickling anti-drip acid flushing hook structure, after the C-type hook and the crossbeam form an integral body, it not only ensures that the C-type hook can lift the weight of 2.5 tons of the material roll, but also ensures that there is no dead angle. The diversion unit forms a certain angle with the crossbeam, which ensures the smooth diversion and flushing water, and ensures that there will be no excess dead angle of the crossbeam to accumulate acid, thereby ensuring the surface quality of the material roll. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1This is a schematic diagram of a rinse hook structure for pickling and anti-drip acid according to an embodiment of the utility model;
[0010] Figure 2 It is a schematic diagram of direction A;
[0011] In the figure, 1 is a crossbeam, 2 is a first guide plate, 3 is a second guide plate, and 4 is a C-type hook. DETAILED DESCRIPTION
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown, a pickling anti-drip acid flushing hook structure in this embodiment includes a crossbeam 1, a C-shaped hook 4 is arranged at the bottom of the crossbeam 1, and the crossbeam 1 and the C-shaped hook 4 are integrated. A U-shaped first guide plate 2 and a U-shaped second guide plate 3 are arranged at the bottom of the crossbeam 1. The first guide plate 2 and the second guide plate 3 are arranged tilted downward respectively, and the tilt directions of the two are opposite. The high end of the first guide plate 2 is connected to the high end of the second guide plate 3. The U-shaped groove of the first guide plate serves as the first guide groove, and the crossbeam 1 is arranged in the first guide groove. The U-shaped groove of the second guide plate serves as the second guide groove, and the crossbeam 1 is arranged in the second guide groove. The lower end (outlet) of the first guide groove and the lower end (outlet) of the second guide groove are both facing the immersion tank. A tap water flushing device is added to the immersion tank. When the material roll comes over, the tap water flushing device flushes the beam. A large amount of flushed acidic liquid will flow to the immersion tank through the first guide groove and the second guide groove. The acid on the beam is cleaned and neutral water is retained. When the subsequent coating reacts, the neutral water drops on the surface of the material roll and will not form rust spots, thereby ensuring the surface quality of the material roll.
[0014] Under the premise of ensuring a load capacity of 2.5T, the thickness of the C-type hook 4 can be reduced by 50mm, and the total length of the beam is 5225mm. The first guide plate and the second guide plate are to ensure that after the thickness of the beam is reduced, there is space when lifting it up for installation, to ensure that the first guide plate and the second guide plate do not scrape the trough cover. Due to the total length of the beam, unilateral inclination will cause a large height difference between the two ends of the guide unit. Therefore, the highest point of the first guide plate and the second guide plate is 3600mm away from the front end of the beam, and the first guide plate and the second guide plate are arranged in sections and tilted on both sides to reduce the height difference.
[0015] After the C-type hook and the crossbeam form a whole, it can ensure that the C-type hook can lift the 2.5-ton weight of the material roll without dead angles. The diversion unit forms a certain angle with the crossbeam to ensure the smooth diversion and flushing water, and ensure that there will be no excess dead angles of the crossbeam to accumulate acid, thus ensuring the surface quality of the material roll.
[0016] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
