Description

Technical Field

[0001] The invention belongs to the field of nondestructive testing equipment, in particular to a nondestructive penetration testing device. Background Art

[0002] Nondestructive penetrant testing refers to the process of penetrating fluorescent penetrants into tiny cracks on the surface of a workpiece, removing the penetrants and moisture on the surface of the workpiece after cleaning and drying, and then applying dry developer powder to the surface of the workpiece. Under the action of capillaries, the penetrants in the cracks are adsorbed to the surface of the workpiece, and then inspecting the surface defects of the parts under a black light. Because of its simplicity, speed, and high cost-effectiveness, it is widely used in aerospace, automobile manufacturing, welding parts inspection, casting parts inspection and many other fields.

[0003] In the existing non-destructive penetrant testing process, the parts need to be placed in a fluorescent penetrant tank to soak in fluorescent penetrant, and then the parts are taken out for spray cleaning, air-dried and then tested by ultraviolet irradiation. When the parts are taken out of the fluorescent penetrant tank, a large amount of fluorescent penetrant liquid will inevitably remain on the basket containing the parts and the surface of the parts. This part of the penetrant liquid will form a large amount of waste liquid containing fluorescent penetrant along with the spray cleaning, which will not only cause waste of resources, but also increase the cost of wastewater treatment and affect the consumption cost of the assembly line.

DETAILED DESCRIPTION

[0026] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0027] See attached Figures 1 to 2 , a non-destructive penetrant testing device, comprising: a fluorescent penetrant component and a hanging conveying component 200. The fluorescent penetrant component includes an ultrasonic cleaning tank 101, a first spray cleaning tank 102, a hot dip cleaning tank 103, a first drying tank 104, a fluorescent penetrant tank 105, a pre-cleaning spray tank 106, an electrostatic spray tank 107, a final cleaning spray tank 108, a manual supplementary cleaning tank 109, and a second drying tank 110. This embodiment provides an exemplary fluorescent penetrant component. There are many different structures for different types of fluorescent penetrant testing devices, but the fluorescent penetrant component should include a fluorescent penetrant tank 105 and a pre-cleaning spray tank 106. The workpiece to be inspected is completely immersed in the fluorescent penetrant tank 105 filled with fluorescent penetrant liquid for penetration. After the penetration is completed, the workpiece to be inspected is transferred to the pre-cleaning spray tank 106 for water spray cleaning. After the cleaning is completed, all the moisture on the surface of the workpiece to be inspected is blown away. The hanging conveyor assembly 200 includes a hanging conveyor device fixedly mounted on the top of the fluorescent penetration assembly, and a transport device slidably mounted on the track of the hanging conveyor device and suitable for loading the workpiece to be inspected.

[0028] In order to realize the recycling and utilization of the fluorescent penetrant liquid, this embodiment designs a circulation system between the fluorescent penetrant tank 105 and the pre-cleaning spray tank 106. Specifically, the discharge port of the pre-cleaning spray tank 106 is connected to an evaporation device. A first storage tank 400 is connected to the bottom of the evaporation device. The first storage tank 400 is suitable for storing the recovered fluorescent penetrant liquid, and the first storage tank 400 is connected to the feed port of the fluorescent penetrant tank 105. The fluorescent penetrant liquid is recycled and reused through the low-temperature negative pressure evaporation device, thereby reducing the discharge of waste liquid and the consumption of fluorescent penetrant liquid.

[0029] In a further embodiment, the evaporation device is a low-temperature negative pressure evaporation device, which prevents the fluorescent penetrant from decomposing or deteriorating at high temperatures, thereby ensuring the stability of the penetrant performance.

[0030] See attached Figure 2 The low-temperature negative pressure evaporation device includes: a pressure vessel 310, a temperature control component 350, a second storage tank 500 and a vacuum pump 360. A steam outlet 320 is provided at the top of the pressure vessel 310, a concentrated liquid discharge outlet 330 is provided at the bottom of the pressure vessel 310, and a waste liquid inlet 340 is provided in the middle of the pressure vessel 310; the temperature control component 350 is provided inside or outside the pressure vessel 310, and the temperature control component 350 includes an electric heating jacket provided on the side wall of the pressure vessel 310, a sensor for detecting the temperature of the waste liquid in the pressure vessel 310, and a controller connected to the electric heating jacket and the temperature sensor. The temperature control component 350 is crucial to the efficiency and product quality of the evaporation process. It is used to accurately control the temperature in the container to ensure that the evaporation is carried out at the set most suitable temperature to avoid the deterioration of the permeate or the reduction of efficiency caused by overheating. In this embodiment, the temperature control component 350 composed of the electric heating jacket, the temperature sensor and the controller accurately controls the temperature in the evaporation process to ensure the evaporation efficiency and the quality of the concentrated liquid. The second storage tank 500 is connected to the steam outlet 320 through a pipeline and a condenser 600. The discharge port of the second storage tank 500 is connected in series to the spray device 700 of the pre-cleaning spray tank 106. The cooling water of the condenser 600 is connected in series to the spray device 700 of the pre-cleaning spray tank 106. Clean water is used as condensed water to cool the steam. After completing the condensation task, it can also be used as a cleaning medium to spray the parts, realizing the multi-level utilization of water resources and maximizing the environmental friendliness and economy of the system. The vacuum pump 360 is connected to the pressure vessel 310 and / or the second storage tank 500. The vacuum pump 360 creates a pressure environment below atmospheric pressure by extracting air or gas in the pressure vessel 310. Such a negative pressure state can reduce the boiling point of the liquid (here, the recovered fluorescent penetrant), so that the evaporation process is carried out at a temperature not exceeding 50°C, protecting the penetrant components from being easily deteriorated due to high temperature, and is also safer and more environmentally friendly.

[0031] In a further embodiment, a debubbling device 800 is further provided between the first storage tank 400 and the evaporation device. In the low-temperature negative pressure evaporation device, a large number of bubbles will be generated in the fluorescent penetrant. If the bubbles are directly reused without being processed, the penetration of the fluorescent penetrant will be affected. After debubbling, the quality of the fluorescent penetrant can be ensured.

[0032] In a further embodiment, a dosing port 410 is provided on the top of the first storage tank 400, and a concentration detection device 420 is provided in the first storage tank 400. Active management and optimization of the quality of the recovered fluorescent penetrant is achieved, and the design of the dosing port 410 allows an operator or an automatic control system to add high-concentration fluorescent penetrant or other regulators to the first storage tank 400 as needed, so as to maintain or improve the detection efficiency of the recovered fluorescent penetrant, and ensure that the penetrant can still meet the sensitivity and quality requirements of the detection even after multiple cycles of use.

[0033] In a further embodiment, at least one filter device 900 is provided between the discharge port of the pre-cleaning spray tank 106 and the evaporation device. The user can design a multi-stage filtration system according to actual conditions and needs, and each stage filters particles of different sizes to achieve a better filtration effect, intercept solid particles, residual metal debris, dust and other impurities carried in the liquid flowing out of the pre-cleaning spray tank 106, prevent these substances from entering the evaporation device, reduce pollution and potential damage to the inside of the evaporator, and improve the quality of the recovered liquid.

[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
