Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing pickling technology, and specifically relates to an environmentally friendly hot-dip galvanizing pickling equipment. Background Technology

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to create an alloy layer, thus bonding the substrate and the coating together. The process begins with pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in the hot-dip galvanizing bath.

[0003] Patent application number 202320010905.1 discloses an environmentally friendly hot-dip galvanizing pickling equipment, including a hot-dip galvanizing pickling tank. The surface of the tank is equipped with a collection component for collecting ammonia and zinc oxide fumes generated during the hot-dip galvanizing pickling process. A collection pipe is fixedly installed on the surface of the tank via the collection component. A treatment component is located at the front of the tank to process the collected ammonia and zinc oxide fumes. This allows the collection pipe to collect zinc oxide fumes and irritating ammonia gas generated during hot-dip galvanizing pickling. The collected zinc oxide fumes and ammonia gas enter the treatment component for further processing, and the clean gas is then discharged. This achieves the goal of easily treating harmful substances generated during hot-dip galvanizing pickling, making the equipment more environmentally friendly and preventing harm to workers from harmful substances, thus avoiding serious illnesses.

[0004] However, the above technical solution only collects the harmful substances generated at the left and right ends of the pickling tank during use. When pickling long workpieces, the harmful substances generated during the pickling process can easily be discharged directly into the atmosphere through the upper, front and rear ends of the pickling tank, causing damage to the environment. Utility Model Content

[0005] In view of this, the present invention provides an environmentally friendly hot-dip galvanizing pickling equipment. The operation of the first mounting plate pushes the pressing mechanism to move, which in turn drives the second side panel to move along the second air supply chamber through the transmission mechanism. The pickling tank is sealed by the first mounting plate, the first side panel and the second side panel. The air pump is started and the harmful substances generated during the pickling process are transported to the filtration mechanism through the air supply pipe. This improves the collection efficiency of harmful substances generated during the pickling process and prevents harmful substances from being directly discharged into the atmosphere from the top, front and rear sides of the pickling tank, thus preventing damage to the environment.

[0006] The technical solution is as follows: An environmentally friendly hot-dip galvanizing pickling equipment includes a pickling tank and a sliding rail.

The multiple gas collection hoods and gas collection holes are all sealed and connected to the second gas delivery chamber. The air pump is sealed and connected to the fourth gas delivery chamber through a gas delivery pipe. The second side panel is driven by the pressing mechanism through a transmission mechanism. By operating the first mounting plate to push the pressing mechanism to move, the second side panel is driven to move along the second gas delivery chamber through the transmission mechanism, thus sealing the pickling tank through the first mounting plate, the first side panel, and the second side panel.

[0007] During use, the above technical solution works as follows: the first mounting plate is operated to push the pressing mechanism to move, which in turn drives the second side panel to move along the second air supply chamber through the transmission mechanism.

[0013] The second connecting mechanism has the same structure as the first connecting mechanism.

[0053] In actual operation: The first driving component 25 is activated, causing the first mounting plate 24 to move along the second mounting plate 26. The first mounting plate 24 then pushes the pressure plate 1504 to move. The pressure plate 1504, through the second sliding plate 1502, pushes the first sliding plate 1501 to move along the first sliding cavity 10, compressing the first elastic component 1503. The pressure plate 1504, through the connecting plate 2204, pushes the piston rod 2203 and piston plate 2201 on the first connecting mechanism 22 to move along the first piston cavity 18, simultaneously compressing the second elastic component 2202 and compressing the gas pressure inside the first piston cavity 18. Because the first piston cavity 18 is sealed to the second piston cavity 20 through the fifth gas supply cavity 17, the second... The gas pressure inside the piston chamber 20 increases, which pushes the piston rod 2203 to move through the piston plate 2201 on the second connecting mechanism 23. At the same time, the second elastic component 2202 is stretched. The piston rod 2203 drives the second side panel 12 to move along the second gas delivery chamber 5, so that the second side panel 12, the first side panel 2, the first mounting plate 24 and the pickling tank 1 form a sealed cavity to prevent harmful gases from leaking out. After pickling is completed, the first driving component 25 is activated to drive the first mounting plate 24 to reset. Under the action of the first elastic component 1503 and the second elastic component 2202, the pressure plate 1504, the first connecting mechanism 22, the second connecting mechanism 23 and the second side panel 12 are reset, which facilitates loading and unloading.
