Description

Technical Field

[0001] The utility model relates to the technical field of equipment leakage blocking, in particular to a device for blocking leakage of a pipe opening of glass-lined equipment. Background Art

[0002] Glass-lined equipment is one of the most important production equipment in petrochemical and pharmaceutical companies. However, during production and use, glass-lined equipment is easily damaged by stress during production, collisions during transportation, loading and unloading, and installation, cold and heat shock during production, and corrosive materials. These factors can render the enamel layer of glass-lined equipment useless.

[0003] The general solutions are: (1) dismantle the glass-lined equipment and return it to the manufacturer for re-enameling. The disadvantages of this method are that it has a great impact on production, a long repair cycle, and high costs; (2) adopt surface coating methods and use various repair agents for repair. The disadvantages of this method are that the temperature changes and material erosion during the use of the glass-lined equipment make the repair agent more likely to fall off, and the surface cleaning, coating, and curing time of the repair process are also long; (3) weld the wire rod where the glass lining falls off, press a piece of polypropylene plate, and then wrap the exposed wire rod and nut with a PP sleeve. The disadvantages of this method are that it is difficult to weld inside the glass-lined equipment, and it is difficult to press tightly if the damaged surface is slightly larger. The bushing will enclose some air while wrapping the wire rod. During use, as the temperature changes, it is easy for materials to penetrate and corrode the wire rod and cause it to be scrapped. (4) Replace new equipment. The disadvantages of this method are high cost and long downtime.

[0004] Based on this, the present utility model is proposed. Utility Model Content

[0030] Common glass-lined equipment in this field such as Figure 1 As shown in Figure 1, it is made by applying a high-silicon glaze to a metal surface and firing it at 950°C to achieve a close bond between the glaze and the metal base. As a result, it possesses the dual advantages of glass-like chemical stability and metallic strength. Currently, glass-lined equipment is widely used in industrial production and scientific research in the chemical, pharmaceutical, dye, pesticide, organic synthesis, petroleum, food manufacturing, and defense industries for reactions, evaporation, concentration, synthesis, extraction, polymerization, saponification, mineralization, chlorination, and nitration processes, replacing expensive stainless steel and non-ferrous metals.

[0031] In the process of production and use, the glass-lined equipment leaks due to corrosion. The utility model provides a glass-lined equipment pipe opening leakage blocking device. The structure of the device is as follows: Figure 2 As shown, it includes a sealing body 6, a round nut 3 and a flange 4.

[0032] The sealing body 6 is a cone-shaped structure as a whole and can be roughly divided into three parts: a first end, a second end and a middle part. The first end has the largest diameter, the middle part has a smaller diameter than the first end, and the second end has the smallest diameter.

[0033] The first end is an expanded portion 8, the diameter of which is larger than the caliber of the leaking portion of the glass-lined equipment 1. Connected to the expanded portion 8 is a circular arc transition portion 11, whose diameter gradually decreases until it becomes equal to or smaller than the caliber of the leaking portion 2. During leak plugging, the circular arc transition portion 11 contacts the leaking portion.

[0034] The other end of seal 6 has a diameter smaller than that of leaking portion 2 and protrudes from inside leaking portion 2, allowing expanded portion 8 of seal 6 to reside inside glass-lined equipment 1, thereby blocking leaking portion 2. The arc-shaped transition portion 11 adjusts the contact area between seal 6 and glass-lined equipment 1, thereby ensuring a tight seal between seal 6 and the leaking portion.

[0035] To further ensure the sealing between the sealing body 6 and the leaking part, the present invention wraps a polytetrafluoroethylene tape 10 around the arc transition part 11 of the sealing body 6. After the other end of the sealing body 6 passes through the leaking part and the position of the sealing body 6 is adjusted, a corrosion-resistant sealant 9 is filled between the sealing body 6 and the leaking part. This method can further improve the sealing between the sealing body 6 and the leaking part.

[0036] The middle section is a columnar structure, with part of it located inside the leaking area and the other part located outside. External threads 7 are provided on the outer wall of the middle section. Once the second end of the seal 6 passes through the leaking area 2 and the seal 6 is properly positioned, the external threads 7 on the outer wall of the middle section secure the round nut 3. By screwing the round nut 3 in, the seal 6 is aligned with the inner wall of the glass-lined equipment 1.

[0037] The second end, distal to the middle portion, has a larger diameter than the end connected to the middle portion, and its cross-section is similar to a "T" shape. In the present invention, the pipe opening sealing device for glass-lined equipment 1 further includes a flange 4 connected to the second end, specifically, below the end distal to the middle portion.

[0038] In the present invention, the flange 4 used is a loose flange 4, which is used to connect pipelines.

[0039] In addition, a through hole 5 is provided in the middle of the sealing body 6 of the present invention, and the through hole 5 is used to communicate with an external pipeline.

[0040] In the present invention, the sealing body 6 is made of polytetrafluoroethylene. The sealing body 6 is made of polytetrafluoroethylene material, which has excellent corrosion resistance.

[0041] When using the glass-lined equipment 1 pipe leak plugging device of the utility model to plug leaks, you can refer to Figure 3 and Figure 4 , the specific operation method is as follows:

[0042] (1) Wrap a polytetrafluoroethylene tape 10 around the arc transition portion 11 of the sealing body 6, and then pass the second end of the sealing body 6 from the inside of the glass-lined equipment 1 through the inner hole of the leakage portion 2 from bottom to top;

[0043] (2) Screw the round nut 3 from the second end until it reaches the outer wall of the middle part, and fill the space between the leaking part 2 and the sealing body 6 with corrosion-resistant sealant 9;

[0044] (3) Tighten the round nut 3 to make the sealing body 6 fit the inner wall of the glass-lined equipment 1;

[0045] (4) Install the loose flange 4 at the second end.

[0046] Through the above steps, the leaking part 2 can be effectively sealed by the leak plugging device of the glass-lined equipment 1, which completely solves the leakage problem and prevents leakage again in a short time. At the same time, it can shorten the downtime for replacement and save the cost of replacing new equipment.

[0047] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and such simple modifications all fall within the scope of protection of the present invention.
