Description

Technical Field

[0001] This utility model relates to the field of smoke extraction structure technology, specifically a smoke extraction structure for an electroplating pickling tank. Background Technology

[0002] Electroplating pickling tanks are key equipment for metal surface pretreatment, primarily used to remove oxide scale, rust, and oil stains from metal surfaces before electroplating, ensuring the adhesion and quality of subsequent electroplating processes. Electroplating pickling tanks remove stubborn stains from metal surfaces through chemical or electrolytic methods and are suitable for pretreatment of materials such as stainless steel, copper, and aluminum. They effectively dissolve high-temperature oxide scale while avoiding the risk of hydrogen embrittlement, ensuring a clean metal substrate and high corrosion inhibition rate. Pickling tanks are an important part of industrial production, but they are also a major source of fumes. These fumes not only pollute the environment but also pose a threat to workers' health. Therefore, these fumes need to be treated, which requires the use of appropriate fume extraction structures. If the fumes are not pretreated, they can easily affect subsequent emissions. Utility Model Content

[0003] The purpose of this invention is to provide a fume extraction structure for an electroplating pickling tank, in order to solve the problem mentioned in the background art that if the fume extraction is not pretreated, it will easily affect subsequent emissions.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fumigation structure for an electroplating pickling tank, comprising a pretreatment box, a connecting pipe, and a fan. A demister is installed at the upper position inside the pretreatment box. Support plates are fixed at the lower positions on both sides of the inner wall of the pretreatment box. Fiberglass filter cotton is arranged above the support plates. Holes are opened on both sides of the fiberglass filter cotton, and positioning posts are inserted into the holes. An upper pressure plate is fixed to the top of the positioning posts. A side plate is fixed at the lower position on the side of the upper pressure plate. The side plate is positioned between the fiberglass filter cotton and the inner wall of the pretreatment box.

[0005] As a further technical solution of this utility model, the support plate is symmetrically distributed about the central axis of the pretreatment box, and multiple sets of glass fiber filter cotton are arranged above the support plate.

[0006] As a further technical solution of this utility model, a connecting pipe is installed on the upper right side of the pretreatment box, and a pipe end plate is connected to the tail end of the connecting pipe. A sealing gasket is bonded to the side of the pipe end plate at the periphery of the opening.

[0007] As a further technical solution of this utility model, the side plate and the upper pressure plate are connected, and the diameter of the positioning column is smaller than the inner diameter of the pores in the glass fiber filter cotton.

[0008] As a further technical solution of this utility model, a second exhaust port is connected and installed at the lower left side of the pretreatment box, and a first exhaust port is connected and installed at the right side of the top of the pretreatment box.

[0009] As a further technical solution of this utility model, a base plate is fixed on the right side of the pretreatment box, and a mounting base is fixed on the top of the base plate, with a rod inserted into the mounting base.

[0010] As a further technical solution of this utility model, a locking pin is inserted between the mounting base and the insertion rod, and locking nuts are threaded to the outer positions on both sides of the locking pin.

[0011] As a further technical solution of this utility model, a support base is fixed to the top of the insertion rod, a semi-circular groove is provided on the support base, an adhesive layer is coated on the semi-circular groove, and a protective pad is bonded to the position of the adhesive layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the smoke extraction structure of this electroplating pickling tank not only improves the pretreatment effect, but also improves the pipe support capacity and connection sealing capacity of the smoke extraction structure. A demister is installed at the top of the pretreatment box to control the exhaust gas temperature. Support plates are fixed to the lower sides of the inner wall of the pretreatment box. Fiberglass filter cotton is arranged above the support plates. Multiple sets of fiberglass filter cotton can be designed. Side plates are then inserted into the gaps on both sides of the fiberglass filter cotton. At this time, positioning columns are inserted into the holes. The upper pressure plate presses on the top layer of fiberglass filter cotton to remove particulate matter and paint residue, protect the subsequent treatment equipment, and thus improve the overall pretreatment capacity. By fixing a base plate to the side of the pretreatment box, the connecting pipe is supported by the semi-circular groove on the support base, and the contact surface is protected by a protective pad. Then, the lower insertion rod is inserted into the mounting base, and after being inserted with a locking pin, the position is locked with a locking nut. This improves the support capacity for the connecting pipe during operation. By connecting and installing a nozzle plate at the end of the connecting pipe, and openings for flow on the nozzle plate, and then bonding and assembling a sealing gasket around the openings, the sealing gasket can correspond to the interface of the pickling tank, thus achieving the purpose of sealing the interface and improving the sealing capability.
