[0014] In one optional embodiment, the lower surface of the buffer plate is provided with a flow guide, which is configured to preferentially cut into the liquid surface, disperse the impact force and guide the liquid to flow in a preset direction to suppress liquid splashing; wherein, when the basket extends into the pool, the buffer plate is driven to flip around the spring hinge toward the bottom of the pool to slow down the falling speed of the basket, and the flipped buffer plate forms a sealing structure with the side wall of the pool to block the splashed solution.
[0015] In one optional embodiment, the flow guide includes a plurality of protruding ribs, which are uniformly arranged along the edge of the lower surface of the buffer plate; the thickness of the protruding ribs gradually decreases from the center of the buffer plate towards both sides.

[0034] Research has revealed the following drawbacks of existing technologies: In centrifugal hot-dip galvanizing, workpieces need to undergo pretreatment such as degreasing and pickling in a pretreatment tank. In related technologies, small workpieces (screws, nuts, and washers, etc.) are usually carried by a basket and immersed in the treatment tank.
[0035] However, during the process of lowering the basket into the treatment tank, the basket is prone to shifting or shaking, causing the solution in the reaction tank to splash. This not only poses a risk of burning operators or contaminating equipment, but also requires frequent replenishment of reagents to adjust the concentration.
[0036] Therefore, how to avoid solution splashing caused by deviation or shaking during the lowering of the basket is a technical problem that urgently needs to be solved in this field.
[0037] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0039] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0040] like Figures 1 to 3 As shown, some embodiments provide a pretreatment tank for centrifugal hot-dip galvanizing, including: a tank body 1 having opposing side walls and a bottom surface; a buffer plate 2, rotatably connected to the top edges of both sides of the tank body 1 via spring hinges 3, and parallel to the solution surface inside the tank body 1; the connection gap between the buffer plate 2 and the spring hinges 3 is made of elastic leather to achieve a relative sealing effect; initially, the spring hinges 3 support the buffer plate 2 in a state parallel to the bottom surface of the tank body 1, such as... Figure 1 As shown, as the basket 4 comes into contact with and descends the buffer plate 2 (as in direction F1), the buffer plate 2 flips towards the bottom of the pool body 1 (as in direction F2) to reduce the speed of the basket 4 from below into the pool body 1 and to improve the stability below.
[0041] When the basket 4 extends into the pool 1, the drive buffer plate 2 rotates around the spring hinge 3 toward the bottom of the pool 1 to slow down the falling speed of the basket 4. The rotated buffer plate 2 forms a sealing structure with the side wall of the pool 1 to block the splashing solution.
[0042] The composition and working effect of the anti-deviation part 21 are described in detail below. The upper surface of the buffer plate 2 is provided with the anti-deviation part 21, which abuts against the bottom surface of the suspended platform 4 to limit the deviation of the suspended platform 4. The anti-deviation part 21 includes elastic strips 211, which are evenly distributed on the upper surface of the buffer plate 2. The elastic strips 211 are X-shaped and / or diagonal strips. The X-shaped elastic strips 211 are arranged alternately at 15°-30°, and the diagonal elastic strips 211 are spaced 50-80mm apart, forming a mesh structure. The X-shaped or diagonal strip structure enhances stability through mechanical guidance, preventing the suspended platform 4 from shifting left and right or forward and backward during lowering. It should be further noted that the elastic deformation of the elastic strips 21 absorbs impact energy, reducing vibration and noise during the descent of the suspended platform 4, protecting the suspended platform 4 and the buffer plate 2. Gradual compression avoids instantaneous rigid collisions. In addition, the elastic strips 21 do not require additional hydraulic or pneumatic buffer devices, reducing costs and facilitating maintenance. The elastic strips are replaceable or adjustable to adapt to different working conditions.
[0043] The composition and working effect of the flow guide 22 are described in detail below. The lower surface of the buffer plate 2 is provided with the flow guide 22, which is configured to preferentially cut into the liquid surface, disperse the impact force, and guide the liquid to flow in a preset direction to suppress liquid splashing. The flow guide 22 includes several protruding ribs 221, which are evenly arranged along the edge of the lower surface of the buffer plate 2. The thickness of the protruding ribs 221 gradually decreases from the center of the buffer plate 2 towards both sides. The end of the protruding rib 221 facing the bottom of the pool body 1 is provided with a sharp corner 222. The protruding ribs 221 will change the contact between the buffer plate 2 and the liquid surface from "large-area planar collision" to "multi-point or linear contact". The protruding ribs 221 first cut into the liquid surface, dispersing the kinetic energy of the buffer plate 2 into multiple small areas, avoiding concentrated impact, thereby reducing the source of kinetic energy for splashing.
[0044] The sharp corner 222 forces the liquid to flow along the direction of the rib 221 (similar to channeling through grooves) instead of splashing randomly in all directions; when the buffer plate 2 impacts the liquid surface at high speed, it is easy to form cavitation (bubbles) below, and the splashing will be aggravated when the cavitation breaks; the sharp corner 222 of the rib 221 can pierce the liquid surface more quickly, reducing the size and stability of the cavitation, that is, reducing splashing by early contact (the tip of the rib contacts the liquid surface first and gradually penetrates, delaying the overall impact), energy dissipation (the friction and cutting action of the rib consumes some kinetic energy, reducing the initial velocity of the liquid splashing), and directional drainage (the gap between the ribs can provide an escape channel for the liquid, avoiding lateral spraying).
[0045] Some embodiments provide a pretreatment tank for centrifugal hot-dip galvanizing, comprising: a tank body 1 having opposing side walls and a bottom surface; a buffer plate 2 rotatably connected to the top edges of both sides of the tank body 1 via spring hinges 3, and parallel to the solution surface within the tank body 1; the upper surface of the buffer plate 2 is provided with an anti-deviation part 21 for abutting against the bottom surface of the basket 4 to limit the deviation of the basket 4; the anti-deviation part 21 includes elastic strips 211 evenly distributed on the upper surface of the buffer plate 2, the elastic strips 211 being X-shaped and / or diagonal strips. The X-shaped elastic strips 211 are staggered at 15°-30°, and the diagonal elastic strips 211 are spaced 50-80mm apart, forming a mesh structure.
[0046] The lower surface of the buffer plate 2 is provided with a flow guide 22, which is configured to preferentially cut into the liquid surface, disperse the impact force, and guide the liquid to flow in a preset direction to suppress liquid splashing. When the basket 4 extends into the pool body 1, the buffer plate 2 is driven to flip around the spring hinge 3 towards the bottom surface of the pool body 1 to slow down the falling speed of the basket 4. The flipped buffer plate 2 forms a sealing structure with the side wall of the pool body 1 to block the splashed solution. The flow guide 22 includes several protruding ribs 221, which are evenly arranged along the edge of the lower surface of the buffer plate 2. The thickness of the protruding ribs 221 gradually decreases from the center of the buffer plate 2 towards both sides. One end of the protruding rib 221 facing the bottom surface of the pool body 1 is provided with a sharp corner 222.
[0047] In summary, the buffer plate 2 connected by the spring hinge 3 can slow down the falling speed of the basket 4. The anti-deviation part 21 on the upper surface of the buffer plate 2 abuts against the bottom surface of the basket 4 to prevent the basket 4 from shaking and improve operational stability. The flow guide part 22 disperses the liquid flow direction to prevent the liquid inside the pool 1 from splashing due to the impact of the basket 4, thus reducing solution splashing. After the lower buffer plate 2 is flipped, it forms a sealing structure with the side wall of the pool 1 to further block splashing, improve the safety of the working environment, and effectively solve the problem of solution splashing caused by deviation or shaking when the basket 4 is lowered.
