Technical Field

[0001] This utility model relates to the field of chemical drums, and in particular to a chemical drum connector device. Background Technology

[0002] In modern chemical production, the safety and reliability of chemical conveying systems directly impact production efficiency and operational safety. As a key interface device for fluid transfer, chemical drum connectors play a crucial connecting role in raw material transport, intermediate transfer, and finished product filling. Empty drum replacement is a frequent operation during chemical transport. Existing chemical drum connector devices have several problems, such as poor sealing leading to chemical leakage, inconvenient installation and disassembly affecting work efficiency, and insufficient resistance to acids and alkalis, making them unsuitable for actual production needs. Utility Model Content

[0003] This application provides a chemical drum connector device, which solves the technical problems of existing chemical drum connector devices, such as poor sealing leading to chemical leakage, inconvenient installation and disassembly affecting work efficiency, and insufficient performance in acid and alkali resistance, making it difficult to meet actual production needs.

[0004] The technical solution adopted in the embodiments of this application is as follows:

[0005] A chemical drum connector includes a drum lid nut, an adapter, a heat-expanding nut, and a retaining ring. The drum lid nut has an annular sealing ring groove on its inner side for embedding a sealing ring. The adapter has an internal thread on its upper part for connecting to a gas pipe connector. The adapter penetrates the inner side of the drum lid nut. A retaining groove is formed on the outer side of the adapter. The drum lid nut is fixed to the retaining groove of the adapter by the retaining ring. Heat-expanding nuts are respectively disposed at both ends of the adapter for connecting to external pipes or equipment.

[0006] A further technical solution is that the bucket lid nut, adapter, heat-expanded nut, and retaining ring are all made of acid and alkali resistant engineering plastics.

[0007] A further technical solution is that the sealing ring and the annular sealing ring groove are interference-fitted.

[0008] A further technical solution is that the internal thread of the adapter is a standard thread, which matches the air pipe connector.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] 1. The use of a cap nut, adapter, heat-expanding nut, and retaining ring, along with acid and alkali resistant engineering plastic material, significantly enhances corrosion resistance. The combination of annular sealing ring groove and interference fit seal improves sealing reliability. The insert structure of the retaining ring and groove achieves axial three-point positioning, and the standard heat-expanding nut shortens assembly and disassembly time. The standard thread design of the adapter improves the compatibility of the gas pipe connector, and the double sealing interface formed by the double heat-expanding nuts effectively eliminates the risk of leakage during chemical transportation. Therefore, the use of acid and alkali resistant materials ensures the service life of the device in harsh chemical environments. The design of the annular sealing ring groove and adapter effectively improves sealing performance and connection convenience, facilitating quick container replacement when empty, improving the efficiency of chemical transportation, and reducing safety issues such as chemical leakage.

[0015] This application provides a chemical drum connector device, which solves the technical problems of existing chemical drum connector devices, such as poor sealing leading to chemical leakage, inconvenient installation and disassembly affecting work efficiency, and insufficient performance in acid and alkali resistance, making it difficult to meet actual production needs.

[0016] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] A chemical drum connector device, such as Figure 1 , Figure 2 and Figure 3As shown, the device includes a lid nut 1, an adapter 2, a heat-expanding nut 3, and a retaining ring 4. The lid nut 1 has an annular sealing ring groove 11 on its inner side for embedding a sealing ring. The adapter 2 has internal threads on its upper part for connecting to a gas pipe connector. The adapter 2 penetrates the inner side of the lid nut 1. The adapter 2 has a retaining groove 21 on its outer side. The lid nut 1 is fixed in the retaining groove 21 of the adapter 2 by the retaining ring 4. Heat-expanding nuts 3 are respectively installed at both ends of the adapter 2 for connecting to external pipes or equipment.

[0019] The bucket lid nut 1, adapter 2, heat-expanded nut 3, and retaining ring 4 are all made of acid and alkali resistant engineering plastics.

[0020] The sealing ring is interference-fitted with the annular sealing ring groove 11.

[0021] The internal thread of adapter 2 is a standard thread, which is compatible with the air pipe connector.

[0022] This embodiment provides a chemical drum connector device, the core structure of which includes a drum lid nut 1 made of acid and alkali resistant engineering plastic, an adapter 2, a heat-expanding nut 3, and a retaining ring 4. During assembly, the sealing ring is first pressed into the annular sealing groove 11 inside the drum lid nut 1 with an interference fit. Then, the adapter 2 is inserted through the drum lid nut 1, and the retaining ring 4 is locked into the retaining groove 21 on the outside of the adapter to achieve axial positioning. The adapter 2 has a standard internal thread machined on its upper part, allowing direct screwing with an air pipe connector. Its two ends are connected to the chemical drum and the conveying pipeline respectively via the heat-expanding nut 3. In practical applications, the operator can quickly assemble and disassemble the pipeline by rotating the heat-expanding nut 3, and the standard thread fit between the adapter 2 and the air pipe connector can instantly establish an air supply channel.

[0023] The use of a drum cap nut 1, adapter 2, heat-expanding nut 3, and retaining ring 4, combined with acid and alkali resistant engineering plastic material, significantly enhances corrosion resistance. The combination of the annular sealing ring groove 11 and the interference fit seal improves sealing reliability. The insertion structure of the retaining ring 4 and the groove 21 achieves axial three-point positioning, and the standard heat-expanding nut 3 shortens assembly and disassembly time. The standard thread design of the adapter 2 improves the compatibility of the gas pipe connector, and the double sealing interface formed by the double heat-expanding nuts 3 effectively eliminates the risk of leakage during chemical transportation. Therefore, the use of acid and alkali resistant materials ensures the service life of the device in harsh chemical environments. The design of the annular sealing ring groove 11 and the adapter 2 effectively improves sealing performance and connection convenience, facilitating quick drum replacement when empty, improving the efficiency of chemical transportation, and reducing safety issues such as chemical leakage.
