Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing equipment, in particular to a high-efficiency hot-dip galvanizing device. Background Art

[0002] Hot-dip galvanizing is a common anti-corrosion protection technology for steel products and an effective way to extend the service life of steel products. The steel products are first pickled to remove the iron oxide on the surface of the steel products, then cleaned with a mixed aqueous solution of ammonium chloride and zinc chloride, and finally immersed in the molten zinc liquid of the hot-dip galvanizing device. After being immersed in the zinc liquid, the surface of the steel products is coated with a zinc alloy coating through the reaction between iron and zinc.

[0003] During the hot-dip galvanizing process of the disc-type steel scaffolding, although the steel parts have been surface treated, some residual iron filings and other impurities will still fall off from the surface of the steel parts during the hot-dip galvanizing process. The steel parts are immersed in the zinc liquid in the hot-dip galvanizing furnace. After the zinc liquid reacts with the steel products many times, it is easy to produce iron slag. The iron slag settles to the bottom of the hot-dip galvanizing furnace and cannot be discharged. Therefore, the floating iron filings and the iron slag at the bottom will affect the subsequent galvanizing effect of the steel products. At present, the iron filings in the galvanizing liquid are cleaned manually using tools, but manual operation has safety hazards, and it is difficult to remove the iron slag and iron filings. Utility Model Content

[0004] The utility model aims to provide an efficient hot-dip galvanizing device to solve the problem raised in the above-mentioned background technology that in the hot-dip galvanizing process of the disc-type steel scaffold, although the steel parts have been surface treated, the remaining iron filings and other impurities will still fall off from the surface of the steel parts during the hot-dip galvanizing process. The steel parts are immersed in the zinc liquid in the hot-dip galvanizing furnace. After the zinc liquid reacts with the steel products for many times, iron slag is easily produced. The iron slag settles to the bottom of the hot-dip galvanizing furnace and cannot be discharged, so that the floating iron filings and the iron slag at the bottom will affect the subsequent galvanizing effect of the steel products. At present, the iron filings in the galvanizing liquid are cleaned manually using tools, but manual operation has safety hazards and it is difficult to remove the iron slag and iron filings.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-efficiency hot-dip galvanizing device, comprising a galvanizing mechanism, a suspension mechanism is provided in the galvanizing mechanism, an oscillation mechanism is fixedly provided at the end of the galvanizing mechanism, the galvanizing mechanism comprises a box body, four rack plates are symmetrically fixedly connected to the top of the box body about its vertical center plane, the suspension mechanism comprises a frame body slidably connected to the inside of the box body, two rotating shafts are symmetrically rotatably connected in the frame body, a bearing plate is fixedly sleeved on the outer walls of the two rotating shafts, a spur gear meshing with the rack plate is fixedly sleeved on the ends of the two rotating shafts, sliding seats are fixedly connected at both ends of the frame body, and limiting columns fixedly connected to the box body are slidably sleeved on the outsides of the two sliding seats, one end of a lifting rope is fixedly connected to the sliding seat, and the other end of the lifting rope is fixedly connected to a winding wheel, the output end of a driving motor is fixedly connected at the center position of the winding wheel, and a positioning wheel wound around the lifting rope is fixedly provided on the top of the limiting column.

[0007] Furthermore, two collecting cavities are symmetrically provided in the box body, two limiting plates are symmetrically fixedly connected to the opposite side walls of the box body, a collecting groove is slidably connected between the two limiting plates, the collecting groove is slidably embedded in the box body, and a pulling handle is fixedly connected to the side wall of the collecting groove.

[0008] Furthermore, two inclined portions are symmetrically arranged on the box body.

[0009] Furthermore, a plurality of filter blocks are fixedly connected to the carrying plate at equal distances.

[0010] Furthermore, the oscillation mechanism includes a servo motor fixedly connected to the side wall of the box body, an eccentric block is fixedly connected to the output end of the servo motor, the top of the eccentric block abuts against a lifting plate, both ends of the lifting plate are rotatably connected to one end of a rotating rod, the other ends of the two rotating rods are rotatably connected to moving arms, positioning columns are fixedly connected to the opposite side walls of the two moving arms, the outer part of the positioning column is slidably sleeved with a knocking column, the outer part of the knocking column is sleeved with a return spring fixedly connected to the knocking column, and a limiting rod is slidably connected between the two moving arms.

[0011] Furthermore, a compression spring is fixedly connected to the top of the lifting plate, and the compression spring is fixedly connected to the box body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The disc-type steel scaffolding can be placed on the bearing plate in the frame, and the box is filled with molten zinc liquid. Then, two driving motors are used to drive the winding wheel to rotate, so that the lifting rope can be gradually released. Then, the bearing plate slowly falls into the box under the action of gravity, and then the zinc liquid forms a uniform and dense zinc coating on the surface of the scaffolding. The iron filings that fall off the surface of the steel parts will float on the surface of the zinc liquid, and the iron slag will sink to the bottom of the bearing plate. Then, the driving motor drives the winding wheel to reel the lifting rope, and then the galvanizing is completed. The steel parts are lifted to the top of the box. Since a plurality of filter blocks are arranged on the carrying plate to filter the zinc liquid, after the steel parts are removed, the carrying plate can be lifted up to pick up the iron filings on the surface of the zinc liquid, so that the spur gear and the rack plate are meshed, which will drive the two carrying plates to flip, and then the iron filings and iron slag on the surface of the carrying plate fall into the collecting chamber. Therefore, the iron filings and iron slag waste in the zinc liquid can be cleaned, thereby ensuring the subsequent galvanizing effect of the steel parts, and no manual cleaning is required, reducing the safety hazards of manual cleaning.

[0014] 2. The eccentric block is driven to rotate through the output end of the servo motor, so that it can resist the lifting plate to rise, and then quickly reset under the extrusion of the extrusion spring. Therefore, the lifting plate will lift and lower vertically reciprocatingly, thereby driving the moving arm to move horizontally reciprocatingly through the rotating rods at both ends of the lifting plate. The positioning column at the top of the moving arm can drive the knocking column to reciprocate and knock the inclined bearing plate. Then, under the continuous vibration of the two bearing plates, the iron filings on their surfaces will slide faster into the collection chamber, thereby improving the cleaning efficiency of the galvanizing equipment and facilitating the rapid galvanizing of subsequent steel parts.

[0015] 3. By setting a sloped portion at the top of the collecting chamber, when the carrying plate is turned over, the iron filings and waste on its surface will slide into the collecting chamber through the sloped portion. The iron filings in the zinc liquid can be collected through the collecting trough, and then the collecting trough can be manually pulled out by pulling the handle to clean it. By regularly cleaning the collecting trough, the cleanliness of the galvanizing equipment can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS
