Description

Technical Field

[0001] This utility model relates to a bend structure for the feed pipe tail tube of a homogenizer, belonging to the field of homogenizer technology. Background Technology

[0002] High-pressure homogenizers are widely used in the dairy, pharmaceutical and chemical industries. The feed pipe tail pipe elbow is a key component connecting the feed pipe and the homogenizing valve. In the existing technology, the feed pipe tail pipe elbow usually adopts the following structure: right-angle elbow or single-layer metal elbow, usually made of stainless steel or carbon steel. The elbow is connected to the pipe by welding or thread.

[0003] However, the abrupt change in the flow channel of a right-angle bend intensifies turbulence and easily leads to material accumulation, especially in high-viscosity or particulate materials. The inner wall of the bend is not treated with wear resistance, and scratches and pits are likely to appear after long-term operation, shortening its service life. The welding method makes it inconvenient to disassemble and assemble the metal bend, while the threaded connection alone is prone to loosening. There is an urgent need for a new bend structure for the feed pipe tailpipe of a homogenizer to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a feed pipe tail bend structure for a homogenizer to solve the problems mentioned in the background. This utility model is based on a streamlined ceramic lining and a modularly designed feed pipe tail bend structure. By optimizing the flow channel shape, enhancing wear resistance, and implementing a modular disassembly design, it solves the problems in existing technologies and improves equipment operating efficiency and maintenance convenience.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a homogenizer feed pipe tail pipe elbow structure, including a main pipe and a stainless steel elbow body. The outer left end of the main pipe is fixed with a collar by a locking bolt. A limiting extension block is longitudinally adhered to the upper end of the collar. A stainless steel clamp is connected to the left end of the collar. A first threaded joint is longitudinally fixed to the upper end of the stainless steel elbow body. A second threaded joint is horizontally fixed to the right end of the stainless steel elbow body. A streamlined ceramic lining is laminated inside the stainless steel elbow body. A tail pipe joint is screwed onto the upper end of the first threaded joint. A second sealing rubber ring is fitted at the connection between the tail pipe joint and the upper end of the stainless steel elbow body. A left retaining ring is fitted to the outer left end of the second sealing rubber ring. A right retaining block is fitted to the outer right end of the second sealing rubber ring. Multiple extension plates are integrally provided at the front and rear ends of the left retaining ring and the right retaining block.

[0006] Furthermore, a flange is longitudinally welded to the right end of the main pipeline, and two branch pipes are longitudinally welded to the upper end of the main pipeline.

[0007] Furthermore, the second threaded connector is screwed into the main pipe, and a first sealing rubber ring is fitted at the connection between the main pipe and the right end of the stainless steel elbow body, and the stainless steel clamp is fitted outside the first sealing rubber ring.

[0008] Furthermore, the streamlined ceramic lining is formed into a gradient arc-shaped flow channel using plasma spraying technology.

[0009] Furthermore, a positioning groove is provided at the left end of the limiting extension block, and a positioning shaft is horizontally inserted in the positioning groove. The left end of the positioning shaft is fixed to the right locking block by a flange and bolts.

[0010] Furthermore, two metal pins are inserted between every two adjacent extension plates, and a magnetic rod is inserted longitudinally between every two metal pins.

[0011] The beneficial effects of this utility model are as follows: The feed pipe tail tube elbow structure of this utility model has a reasonable structure due to the addition of a collar, locking bolt, limiting extension block, stainless steel clamp, stainless steel elbow body, first threaded joint, second threaded joint, streamlined ceramic lining, left clamping ring, right clamping block, positioning shaft, extension plate, metal pin, and magnetic rod. Based on the streamlined ceramic lining and modular design of the feed pipe tail tube elbow structure, the optimization of the flow channel shape, the enhancement of wear resistance, and the modular disassembly design solve the problems in the prior art, improve the equipment operating efficiency and maintenance convenience, and has strong practicality.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a homogenizer feed pipe tail pipe elbow structure, including a main pipe 1 and a stainless steel elbow body 8. A collar 3 is fixedly fitted onto the left end of the main pipe 1 by a locking bolt 4. A limit extension block 5 is longitudinally adhered to the upper end of the collar 3. A stainless steel clamp 6 is connected to the left end of the collar 3. A first threaded connector 9 is longitudinally fixed to the upper end of the stainless steel elbow body 8. A second threaded connector 10 is horizontally fixed to the right end of the stainless steel elbow body 8. A streamlined ceramic lining 11 is laminated inside the stainless steel elbow body 8. A tail pipe connector 12 is screwed onto the upper end of the first threaded connector 9 via threads. A second sealing rubber ring 13 is fitted at the connection between the head 12 and the upper end of the stainless steel elbow body 8. A left retaining ring 14 is fitted at the left end of the second sealing rubber ring 13, and a right retaining block 15 is fitted at the right end of the second sealing rubber ring 13. Multiple extension plates 17 are integrally set at the front and rear ends of the left retaining ring 14 and the right retaining block 15. This design solves the problems of the original right-angle elbow flow channel change causing increased turbulence, easy material accumulation, lack of wear-resistant treatment on the inner wall of the elbow, easy scratches and pits after long-term operation, shortening service life, inconvenient disassembly and assembly through welding, and easy loosening through threaded connection.

[0019] As the first embodiment of this utility model: a flange is longitudinally welded to the right end of the main pipe 1, and two branch pipes 2 are longitudinally welded to the upper end of the main pipe 1. The addition of the flange longitudinally welded to the right end of the main pipe 1 facilitates connection to the homogenizer pump body via bolts. The second threaded joint 10 is screwed into the inside of the main pipe 1, and a first sealing rubber ring 7 is fitted at the connection between the main pipe 1 and the right end of the stainless steel elbow body 8. A stainless steel clamp 6 is fitted outside the first sealing rubber ring 7. The added first sealing rubber ring 7 can cover the connection between the main pipe 1 and the right end of the stainless steel elbow body 8, and the stainless steel clamp 6 can lock and reinforce this position, ensuring the sealing of the connection between the main pipe 1 and the right end of the stainless steel elbow body 8.

[0020] The streamlined ceramic lining 11 uses plasma spraying technology to form a gradient arc-shaped flow channel. This reduces fluid turbulence and deposition, and the gradient arc-shaped flow channel ensures a smooth fluid transition, reducing fluid resistance by more than 15%. The ceramic lining has high hardness (Mohs hardness ≥ 8), significantly improving wear resistance. The left end of the limiting extension block 5 has a positioning groove, and a positioning shaft 16 is horizontally inserted into the positioning groove. The left end of the positioning shaft 16 is connected and fixed to the right locking block 15 via a flange and bolts. This connection provides auxiliary support to the right locking block 15, preventing it from loosening on its own. Two metal pins 18 are inserted between every two adjacent extension plates 17, and a magnetic rod 19 is inserted longitudinally between every two metal pins 18. By adding two metal pins 18 between every two adjacent extension plates 17, the connection between the left retaining ring 14 and the right retaining block 15 can be realized. Furthermore, the magnetic rod 19 inserted longitudinally between every two metal pins 18 can securely fasten multiple extension plates 17 together, ensuring the strong connection between the left retaining ring 14 and the right retaining block 15.

[0021] As a second embodiment of this utility model: In actual installation, the upper outer end of the first threaded connector 9 is screwed onto the tailpipe connector 12. Then, the second sealing rubber ring 13 is fitted onto the connection between the tailpipe connector 12 and the upper end of the stainless steel elbow body 8. The left retaining ring 14 is attached to the left side of the second sealing rubber ring 13, and the right retaining block 15 is attached to the right side of the second sealing rubber ring 13, so that the multiple extension plates 17 are in contact. Then, two metal pins 18 are inserted between every two contacting extension plates 17. Next, the magnetic rod 19 is inserted between every two metal pins 18, and the magnetism of the magnet ensures that the magnetic rod 19 will not loosen. Then, the second threaded connector 10 is screwed into the left end of the main pipe 1, and the first sealing rubber ring is... 7 is set at the connection between the stainless steel elbow body 8 and the left end of the main pipe 1. Then, the stainless steel clamp 6 and collar 3 outside the main pipe 1 are moved to the left until the stainless steel clamp 6 is set outside the first sealing rubber ring 7. Then tighten the stainless steel clamp 6. At this time, the right end of the positioning shaft 16 will also be inserted into the positioning groove. When in use, the streamlined ceramic lining 11 uses plasma spraying technology to form a gradient arc flow channel, which reduces fluid turbulence and deposition. The gradient arc flow channel makes the fluid transition smoothly, reducing fluid resistance by more than 15%. The ceramic lining has high hardness (Mohs hardness ≥ 8), which significantly improves wear resistance. (Note: The right end of the main pipe 1 has a flange welded longitudinally, which is convenient to connect to the homogenizer pump body by bolts. It is an existing device, and the working principle is not described in detail.)
