Description

TECHNICAL FIELD

[0001] The present application relates to the field of box welding reinforcement, in particular to a leak-proof box welding reinforcement process and a condensation recovery box using the process. BACKGROUND

[0002] In industrial production, heat exchange equipment is usually used for industrial heat exchange treatment, and condensation recovery is an important industrial step. The condensation recovery tank is an essential part of the heat exchange equipment. The condensation recovery tank used in current industrial heat exchange equipment is usually a huge cuboid tank built by combining multiple single-sided steel plates. In order to ensure its reliability and stability, the outside of the tank needs to be welded and reinforced with a frame to support the tank. To ensure the quality of the finished industrial condensation recovery tank, leak point inspection is required. For example, the soap bubble inspection method is one of the methods commonly used at present. If there is a leak point, soap bubbles will overflow from the leak point and accumulate at the leak point. Therefore, inspectors can quickly observe the leak point from the outside and mark it. Subsequently, the leak point is repaired in turn.

[0003] However, the current industrial condensation recovery tank has the following problems: 1. The size of the condensation recovery tank is huge, built by combining multiple single-sided steel plates, with large welding deformation and uneven tank surface; 2. Leak points usually occur at corners. When checking for leak points, if the leak point is located just below the corner reinforcement frame, the soap bubbles can only overflow from the gap in the reinforcement frame. At this time, the inspector observes the overflowing soap bubbles along a line of the reinforcement frame, and cannot quickly determine the exact location of the leak point. It needs to be checked one by one in the area where the soap bubbles overflow, which requires a lot of time and effort. Since the tank size is large and the number of reinforcement frames is large, the above situation occurs with a high probability; 3. The number of reinforcement frames is large, so the number of welds is large, and the number of leak points caused by welding increases. The above situations are not conducive to the quality of the condensation recovery tank and the efficiency of quality inspection. Our company improves the condensation recovery tank welding reinforcement process to solve the above problems. SUMMARY

[0004] The present application is a leak-proof box welding reinforcement process and a condensation recovery tank using the process to solve the problem of large welding deformation of the condensation recovery tank, uneven tank surface, and inability to quickly and accurately locate the leak point after the reinforcement welding is completed, resulting in low inspection efficiency and missed inspection.

[0031] For the purpose, structure, features, and functions of the present application, further understanding, detailed description is as follows with examples.

[0032] Please refer to Figures 1-5 The present application provides a leakage-proof box welding reinforcement process, comprising the following steps:

[0033] S1, raw material preparation; prepare the box material of the condensation recovery box, including the single-sided panel material 1 of the box, the single-sided reinforcement frame strip 2, and the corner reinforcement frame strip 3;

[0034] S2, single-sided welding reinforcement; weld the single-sided reinforcement frame strip 2 on the single-sided panel material 1 of the condensation recovery box, and the single-sided reinforcement frame strip 2 is used to support the single-sided panel material 1 of the box;

[0035] S3, main box building; the single-sided panel material 1 of the box after welding and reinforcement is assembled into the main box of the condensation recovery box, and full welding is performed;

[0036] S4, leakage point inspection and repair; the main box after full welding is assembled is subjected to leakage point inspection, and the leakage points found are repaired one by one;

[0037] S5, corner welding reinforcement; the corner reinforcement frame strip 3 is installed at the corner of the repaired main box, and the corner reinforcement frame strip 3 is welded on the single-sided reinforcement frame strip 2 connected therewith, and is not connected with the single-sided panel material 1 of the box;

[0038] S6, the box reinforcement welding is completed, and the box finished product is inspected and then stored or enters the next production step.

[0039] The leakage-proof box welding reinforcing process provided by the present application is an improvement on the existing condensation recovery box body welding reinforcing process. In the reinforcing process, reinforcing is performed on the box corner in addition to the welding reinforcing on the box single panel 1. In the prior art, the box body is first assembled by the box single panel 1, and then welding reinforcing is performed on the outside of the box body. Due to the large size of the industrial condensation recovery box body, the box single panel deforms due to its own gravity and the weight of other panels before welding reinforcing. Even if reinforcing frame strips are welded on the box single panel and the corner afterwards, the deformation of the box body cannot be completely eliminated. In the welding reinforcing process of the present application, the single reinforcing frame strip 2 is first welded on the box single panel 1, so that the box single panel 1 can be well supported and reinforced, and then the box single panel 1 is assembled into the condensation recovery box body. This makes the box single panel well supported, the deformation of the box single panel is small after being assembled into the box body, and the flatness of each face is ensured. Therefore, compared with the condensation recovery box body produced by the existing reinforcing process, the deformation of the box body is greatly reduced, the flatness of each face of the box body is greatly improved, and the support effect and reliability of the box body are greatly improved.

[0040] The box body reinforcing of the condensation recovery box includes box single panel reinforcing and box corner reinforcing. In the prior art, the box single panel is first assembled into the box body, and then the box single panel and the corner are simultaneously reinforced. After the reinforcing is completed, leakage point inspection is performed. In the present application, the single reinforcing frame strip 2 is first welded on the box single panel 1 to reinforce it, and then the reinforced box single panel 1 is assembled into the box body and fully welded. At this time, leakage point inspection is performed first. After the leakage points are found one by one and repaired, it is confirmed that there are no leakage points, and then the corner reinforcing frame strip 3 is welded on the corner of the box body. The leakage point inspection is usually performed by the soap bubble method or the pressure inspection method. In the soap bubble method, soap water is applied to the outside of the box body, and gas is blown into the box body in the same direction. If there is a leakage point, soap bubbles will appear at the leakage point, and the inspector can quickly find and accurately locate the leakage point. In the pressure inspection method, pressure is applied to one side of the box body, and a detector is used to detect whether there is a change in the pressure value at the other side. If there is a change in the pressure, there is a leakage point. Compared with the prior art, since the corner reinforcing is not performed when the leakage point inspection is performed, the leakage point at the corner can be quickly found and repaired, which greatly saves the time for finding the leakage point and solves the problem that the soap bubbles extend and overflow along the gap due to the corner reinforcing frame strip 3 shielding the leakage point at the corner.

[0041] The corner reinforcing frame 3 of the present application is welded on the single-face reinforcing frame 2 connected therewith, and is not connected with the box single-face panel 1, so that the reinforcement and support of the box corner can be realized, and the secondary welding leakage caused by welding on the box again can be avoided, the new leakage point on the box of the condensate recovery tank is ensured, and the product quality of the condensate recovery tank is ensured.

[0042] The welding and reinforcing process of the condensate recovery tank is improved, the welding, assembling and leakage point inspection sequence are adjusted, and the actual welding position of the corner welding and reinforcing is changed, so that the deformation amount of the finished product of the condensate recovery tank is greatly reduced, and the leakage point inspection efficiency and accuracy are greatly improved.

[0043] In an embodiment, at least two single-face reinforcing frames 2 are welded on each box single-face panel 1; preferably, the single-face reinforcing frame 2 is a long strip-shaped fixed strip, and the inside is a solid structure or a hollow structure. A plurality of single-face reinforcing frames 2 are welded on the same box single-face panel 1 for reinforcement and support, the single-face reinforcing frame is designed as a long strip, the width is relatively narrow, the length is convenient to cut, and the plurality of single-face reinforcing frames are welded on the single-face panel at intervals, the actual size of the box single-face panel 1 can be cut into different lengths, the production is more convenient to cut and match the single-face panel of the condensate recovery tank of different models, and the production efficiency is improved. In addition, since the corner reinforcing frame 3 of the present application finally needs to be welded on the expected corresponding single-face reinforcing frame 2, the single-face reinforcing frame 2 is convenient and accurate to cut to length, which is beneficial to abutting contact with the corner reinforcing frame 3, and then beneficial to the welding quality.

[0044] Further, the single-face reinforcing frames 2 are arranged in a grid shape and welded on the box single-face panel 1. The number of single-face reinforcing frames 2 on the box single-face panel 1 is relatively large, and there is intersection between them, which is preferably divided into vertical horizontal and vertical vertical welding intersections, so that the support effect is better, and the deformation amount of the box single-face panel 1 is smaller.

[0045] In an embodiment, the shape and size of the box single-face panel 1 are changed according to the specific requirements of the condensate recovery tank. Since the overall shape of the condensate recovery tank is similar to a cuboid, and the actual shape is slightly different, such as some faces provided with openings, some faces provided with protruding parts or recessed parts, and the shapes and sizes of condensate recovery tanks of different models are different, the box single-face panels 1 prepared in S1 are different, and the single-face reinforcing frames 2 can be cut and arranged according to the box single-face panels 1 of different models to obtain the best support effect.

[0046] Preferably, in S4, the leakage points are checked and repaired one by one, and after the repair, the leakage point checking is performed again until no leakage point is found, and then S5 is performed. One of the great improvements of the present application compared with the prior art is that the step of checking the leakage points is performed before the corner reinforcing step, so that the leakage point checking of the corner is more accurate and fast, and the repair is more convenient, so that it is necessary to confirm that the leakage points have been checked and repaired completely before S5, and the corner reinforcing frame 3 in S5 is not welded with the single-face reinforcing plate of the box body, so that no welding point is added on the single-face plate 1 of the box body to cause welding leakage.

[0047] In an embodiment, the corner reinforcing frame 3 covers the corner where the edges of two adjacent single-face plates 1 of the box body meet, and the corner reinforcing frame 3 is welded with the single-face reinforcing frame 2 on the two single-face plates 1.

[0048] A condensate recovery tank using the leakage-proof box body welding and reinforcing process of any one of the above embodiments comprises single-face plates 1, single-face reinforcing frames 2 and corner reinforcing frames 3; the single-face reinforcing frames 2 are welded on the single-face plates 1, and the single-face plates 1 are assembled to form a main body of the condensate recovery tank, and the corner reinforcing frames 3 are installed at the corner edges of the main body of the condensate recovery tank and are fixed by being welded with the single-face reinforcing frames 2.

[0049] The condensate recovery tank of the present application is different from the existing condensate recovery tank in structure except the welding and reinforcing process, and the most core difference is that the corner reinforcing frame 3 is welded with the single-face reinforcing frame 2 but not in contact with the single-face plate 1, so that the accuracy and convenience of leakage point checking are improved, and the leakage caused by secondary welding is avoided.

[0050] The present application has been described by the above-mentioned embodiments, however, the above-mentioned embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, the changes and modifications made without departing from the spirit and scope of the present application are within the scope of the patent protection of the present application.
