Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-frost technology, specifically an anti-frost wrapping structure for fresh milk pipelines in fresh milk cold storage. Background Technology

[0002] Fresh milk pipes in cold storage facilities need to be kept at a low temperature of 0-4℃, but their surfaces are prone to frost formation due to contact with the humid air inside the cold storage. In particular, frost is more likely to form at joints, valves and other parts due to cold leakage.

[0003] The common method for preventing frost formation on pipes in fresh milk cold storage is to wrap them with insulation cotton and then secure them with wire. This process requires manual wrapping section by section, which is tedious and time-consuming. During maintenance, the wire and insulation layer need to be removed, and reinstallation is prone to poor fit, leading to cold leakage and frost formation. This makes maintenance troublesome and affects work efficiency. Therefore, we propose an anti-frost wrapping structure for fresh milk pipes in fresh milk cold storage. Utility Model Content

[0004] The purpose of this invention is to provide an anti-frost wrapping structure for fresh milk pipelines in fresh milk cold storage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-frost wrapping structure for fresh milk pipelines in a fresh milk cold storage, comprising a pipeline body, connecting flanges set at both ends of the pipeline body, and semi-circular protective sleeves respectively set at the upper and lower ends of the pipeline body; The main body of the pipe is fixedly connected to an external threaded mounting ring on one side of the connecting flange. The upper and lower ends of the opening on one side of the external threaded mounting ring are provided with limit holes. The external threaded mounting ring is threadedly connected to an internal threaded rotating cylinder. An internal threaded rotating ring is fixedly connected to one side of the internal threaded rotating cylinder. The two ends of the semicircular protective sleeve are fixedly connected to external threaded half rings. The middle of the inner ring of the external threaded half ring is fixedly connected to a limit block. The inner ring wall of the semicircular protective sleeve is provided with an inner aerogel felt.

[0006] Preferably, the inner diameter of the limiting hole matches the outer diameter of the limiting block.

[0007] Preferably, the outer wall of the internally threaded rotary cylinder is provided with several grooves.

[0008] Preferably, all the internally threaded swivels are threadedly connected to the externally threaded mounting rings, and all the externally threaded semi-rings are threadedly connected to the internally threaded swivels.

[0009] Preferably, a sealing gasket is provided at the edge connection of the semicircular protective sleeve, and a U-shaped sealing gasket is provided on the inner ring wall of the external thread semi-ring near the limiting block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the semi-circular protective sleeve snap-fit ​​design, combined with the threaded connection of the external threaded semi-ring and the internal threaded swivel, replaces the traditional wire wrapping, making installation and disassembly convenient and reducing operation time. The inner aerogel felt enhances the heat preservation effect and blocks the leakage of cold air. The sealing gasket and U-shaped sealing gasket eliminate the gaps between joints and components, preventing water vapor from seeping in and frosting. The overall structure improves the anti-frost stability, facilitates later maintenance, and is suitable for the high-efficiency operation requirements of fresh milk cold storage pipelines.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1-4 As shown, this utility model provides the following technical solution: Example 1: Anti-frost wrapping structure for fresh milk pipelines in fresh milk cold storage, including pipeline body 1, connecting flanges 11 set at both ends of pipeline body 1, and semi-circular protective sleeves 2 respectively set at the upper and lower ends of pipeline body 1.

[0015] When in use, fasten the two semi-circular protective sleeves 2 from the top and bottom of the pipe body 1 to wrap around the pipe and the edge of the connecting flange 11. By fitting the pipe, a closed protective space is formed, which reduces the direct contact between the pipe and the humid air in the cold storage. The protective sleeves prevent cold energy from leaking out and reduce the probability of frost formation.

[0016] Example 2: The technical solution of this example, which differs from Example 1, includes: The pipe body 1 is fixedly connected to an external threaded mounting ring 12 on one side of the connecting flange 11. Limiting holes 101 are drilled through the upper and lower ends of the opening on one side of the external threaded mounting ring 12. An internal threaded rotating cylinder 13 is threadedly connected to each external threaded mounting ring 12. An internal threaded rotating ring 14 is fixedly connected to one side of each internal threaded rotating cylinder 13. External threaded semi-circular protective sleeve 2 is fixedly connected to both ends of each end. The middle of the inner ring of each external threaded semi-circular protective sleeve 21 is fixedly connected to... The limit block 22 and the inner ring wall of the semicircular protective sleeve 2 are both provided with inner aerogel felt 23. The inner diameter of the limit hole 101 is matched with the outer diameter of the limit block 22. The outer wall of the internal threaded rotating cylinder 13 is provided with several grooves. The internal threaded rotating cylinder 13 is threadedly connected to the external threaded mounting ring 12. The external threaded semi-ring 21 is threadedly connected to the internal threaded rotating ring 14. The edge connection of the semicircular protective sleeve 2 is provided with sealing gasket 24. The inner ring wall of the external threaded semi-ring 21 is provided with a U-shaped sealing gasket 25 on the side near the limit block 22.

[0017] In use, the two semi-circular protective sleeves 2 are fastened to the outside of the pipe body 1, so that the external threaded semi-rings 21 at both ends are attached to the outer wall of the external threaded mounting ring 12, so that the limiting block 22 is accurately engaged in the limiting hole 101 for positioning. Then, the grooved internal threaded rotating cylinder 13 is rotated to connect with the external threaded mounting ring 12, while the internal threaded rotating ring 14 is driven to tighten the external threaded semi-rings 21. The inner aerogel felt 23 strengthens the insulation and prevents frost from forming on the outer surface of the pipe body 1. The sealing gasket 24 seals the joint of the protective sleeve, and the U-shaped sealing gasket 25 seals the gap between the external threaded semi-rings 21 and the external threaded mounting ring 12. After the whole is locked, a gapless insulation layer is formed, which has a better anti-frost effect and is easy to disassemble and assemble.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
