Description

Technical Field

[0001] The utility model relates to the technical field of corrosion-resistant detection equipment, in particular to a corrosion-resistant detection device for the furnace plate of a box furnace. Background Technique

[0002] For the salt spray corrosion resistance detection of the furnace plate, the core purpose is to evaluate its performance in a salt-containing corrosion environment and ensure the safe and stable operation of the equipment. In industries such as chemical engineering, shipbuilding, and energy, the furnace plate is often exposed to chlorine-containing salt spray. The chloride ions in the salt spray have strong penetrability and are easy to damage the metal surface oxide film, causing local corrosion such as pitting corrosion and crevice corrosion, threatening the structural strength and sealing performance of the furnace plate. Through salt spray detection, corrosion-resistant materials can be screened and the protective effect of surface treatment processes can be verified;

[0003] When the existing furnace plates are subjected to salt spray corrosion resistance detection, they are mostly directly placed in a salt spray corrosion resistance detection box for operation. However, the existing salt spray corrosion resistance detection equipment lacks portability. Traditional salt spray test boxes are large in volume and fixed in structure, and rely on a professional laboratory environment for deployment, making it difficult to meet the on-site rapid detection requirements. Especially in scenarios such as chemical industrial parks and coastal power plants, the furnace plates to be tested need to be transported back and forth to the laboratory, resulting in an extended detection cycle and increased costs. In addition, the handling of large-sized furnace plates is inconvenient. The existing equipment hatch size is limited, and multiple people need to cooperate or use lifting tools to complete the specimen loading and unloading. During the process, the specimen surface is easily damaged due to bumping, affecting the accuracy of the detection results. Content of the Utility Model

[0004] The purpose of the utility model is to provide a corrosion-resistant detection device for the furnace plate of a box furnace, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A corrosion-resistant detection device for the furnace plate of a box furnace includes a transfer pump and a salt spray spraying mechanism. The transfer pump is electrically connected to an external power supply through a cable, and the input end of the transfer pump is connected to an external liquid storage pipe through a pipeline. The salt spray spraying mechanism further includes a first base. Both ends of the first base are movably installed with first connecting rods. One end of the first connecting rod away from the first base is movably installed with a second connecting rod. One end of the second connecting rod away from the first connecting rod is movably installed with a sealing cover. A connecting rubber pad is fixedly connected between the two sealing covers. A Z-shaped pulling plate is rotatably installed on one side of each of the two second connecting rods.

[0007] As a further preferred solution of the utility model, two first pin shafts are inserted into the first base, and one end of the first connecting rod is rotatably installed on one of the first pin shafts.

[0008] As a further preferred embodiment of the present invention, a second base is fixedly installed on one end of the second connecting rod, and a third base is fixedly installed on the other end. A third pin is inserted in the second base, and a second pin is inserted in the third base. The third base is rotatably installed on one end of the first connecting rod through the second pin, and the second base is rotatably installed on one end of the second connecting rod through the third pin. The second connecting rod is rotatably connected to the first connecting rod, which can provide multi-directional and multi-angle adjustment for the use of the sealing cover to adapt to furnace plates of different thicknesses.

[0009] As a further preferred embodiment of the present invention, a fixed tube is fixedly installed on one side of the sealing cover, a connecting port is fixedly installed on the fixed tube, and the connecting port is connected to the output end of the delivery pump through a pipeline, and the fixed tube is fixedly installed on one side of the second base on the side away from the sealing cover, and the two sealing covers cooperate with the connecting rubber pads to be clamped at the edge of the furnace plate and can also be unfolded to contact the surface of the furnace plate for salt spray corrosion resistance testing.

[0010] As a further preferred solution of the utility model, an atomizing nozzle is fixedly installed in the sealing cover, and the atomizing nozzle is connected to the connection port cavity through a fixed pipe.

[0011] As a further preferred embodiment of the present invention, a sealing skirt is fixedly installed along the outer contour of the connecting rubber pad, and two drainage pipes are fixedly installed inside the sealing skirt. The two sealing covers are connected by the connecting rubber pad, so that the edge of the furnace plate can be clamped and sealed, thereby realizing multi-point salt spray corrosion resistance testing.

[0012] As a further preferred embodiment of the present invention, a tension bolt is movably connected between the two Z-shaped pull plates. The two Z-shaped pull plates are movably connected by the tension bolt, and relative tension can be applied to the two second connecting rods, so that the two sealing covers are clamped at the edge of the furnace plate by the connecting rubber pads.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, the sealing cover can be flexibly opened and closed through the cooperation of the movable connecting rod structure and the Z-shaped pull plate and the tension bolt, so that it is convenient to quickly clamp it on the edge of the furnace plate or touch its surface, meeting the needs of rapid on-site detection, without the need to go back and forth to the laboratory, shortening the detection cycle and reducing costs.
