Description

Technical Field

[0001] This utility model provides an anti-clogging device for cold storage drainage pipes, belonging to the field of refrigeration technology. Background Technology

[0002] The cold storage drainage system is a crucial component for maintaining the internal environment and ensuring the efficient operation of refrigeration equipment. Its core function is to promptly remove meltwater generated during the periodic defrosting of the evaporator. Because the interior of cold storage is constantly at sub-zero temperatures, drainage pipes must have effective antifreeze measures. Currently, laying electric heating tape on the outer wall of the drainage pipes has become the most mainstream antifreeze technology in the industry. The electric heating tape activates during the defrosting cycle, continuously replenishing heat to the pipes to ensure that meltwater remains liquid as it flows through the low-temperature area. This effectively solves the problem of blockage caused by freezing inside the pipes and ensures smooth drainage.

[0003] Due to structural requirements, the drain end of a drain pipe must be connected to the external atmosphere. This opening allows suspended impurities such as dust and fibers from the outside environment to easily enter the drain end. After defrosting and when the electric heating tape stops working, a small amount of residual water remains at the end of the drain pipe. In extremely cold environments, this residual water freezes rapidly, firmly freezing any dust particles already in the pipe, forming a mixed ice deposit at the drain end. With repeated defrosting cycles, this ice deposit accumulates layer by layer, eventually causing localized blockage at the drain end. When such blockages need to be cleaned, the adsorption effect of the ice layer greatly increases the difficulty of cleaning, and it is very easy to push the ice deposit further into the drain pipe during cleaning. Although the electric heating tape can be restarted to melt the ice, its heating rate is relatively slow, aiming to prevent the pipe from freezing rather than to quickly melt the ice. This significantly delays the cleaning process, resulting in low maintenance efficiency. Therefore, a new anti-clogging device that can quickly solve the problem of ice deposits formed by residual water at the drain end is particularly necessary. Utility Model Content

[0004] The technical problem this invention aims to solve is that ice deposits easily form at the drain end of drainage pipes, greatly increasing the difficulty of unclogging, and making it very easy to push the ice deposits into the drain pipe during cleaning.

[0005] In order to solve the above problems, the present invention proposes the following technical solution: a cold storage drainage pipe anti-clogging device, comprising a drainage pipe and an electric heating tape, wherein the electric heating tape is installed on the outer wall of the drainage pipe;

[0006] The drain end of the drain pipe is threadedly connected to a detachable operating cylinder. A scraping component is installed inside the drain pipe to scrape the ice and dirt on the inner wall of the drain pipe. The scraping component is fixedly connected to the operating cylinder via a connecting rod. A crushing component is fixedly connected to the connecting rod to break up the ice and dirt on the inner wall of the drain pipe.

[0007] As an improvement, the scraping assembly includes a sliding plate and a scraper; the sliding plate is disposed inside the drain pipe near the drain end, and the scraper is fixedly connected to the sliding plate.

[0008] As an improvement, the scraper is tightly fitted to the inner wall of the drain pipe, and the scraper has a tapered cross-section; the sliding plate has a through hole in the center, the sliding plate is fixedly connected to the connecting rod, and the connecting rod is fixedly connected to the operating cylinder.

[0009] As an improvement, the drain end of the drain pipe is fixedly connected to a threaded cylinder, and the inner wall of the operating cylinder is provided with an internal thread that can be threadedly connected to the threaded cylinder.

[0010] As an improvement, the crushing component is a crushing rod, with several crushing rods fixedly connected to the connecting rod, and the ends of the crushing rods located near the inner wall of the drain pipe.

[0011] As an improvement, a removable sealing plug is threaded onto the end of the operating cylinder away from the drain pipe.

[0012] The beneficial effects of this utility model are:

[0013] A detachable operating cylinder is threadedly connected to the drain end of the drain pipe, and a scraping component is fixedly connected to the operating cylinder via a connecting rod; a crushing component is fixedly connected to the connecting rod. This application directly places the crushing component and the scraping component inside the drain pipe. When the operating cylinder is rotated to remove it, the rotation of the operating cylinder simultaneously drives the crushing component to rotate, thereby improving the ice-breaking effect. There is no need to wait for the ice and dirt to completely melt, resulting in high cleaning and maintenance efficiency. Furthermore, while removing the operating cylinder, the scraping component pushes the ice and dirt outwards, preventing them from moving inwards and improving the cleaning effect.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This utility model provides an anti-clogging device for cold storage drainage pipes: including a drainage pipe 1 and an electric heating tape 2. The electric heating tape 2 is installed on the outer wall of the drainage pipe 1 and can provide a stable heat source for the drainage pipe 1 to prevent the drainage pipe 1 from freezing and clogging.

[0021] Reference Appendix Figure 1 , 2 4. A detachable operating cylinder 3 is threadedly connected to the drain end of the drain pipe 1, and a threaded cylinder 8 is fixedly connected to the drain end of the drain pipe 1. The inner wall of the operating cylinder 3 is provided with an internal thread that can be threadedly connected to the threaded cylinder 8. A scraping component is provided inside the drain pipe 1 to scrape the ice and dirt on the inner wall of the drain pipe 1, and the scraping component is fixedly connected to the operating cylinder 3 through a connecting rod 7.

[0022] The scraping assembly includes a sliding plate 5 and a scraper 10. The sliding plate 5 is positioned inside the drain pipe 1 near the drain end, and the scraper 10 is fixedly connected to the sliding plate 5. The scraper 10 fits tightly against the inner wall of the drain pipe 1, and the scraper 10 has a tapered cross-section. When the operating cylinder 3 is disassembled, the operating cylinder 3 drives the sliding plate 5 and the scraper 10 to move, thereby allowing the scraper 10 to scrape away the ice and dirt on the inner wall of the drain end of the drain pipe 1.

[0023] The sliding plate 5 is fixedly connected to the connecting rod 7, and the connecting rod 7 is fixedly connected to the operating cylinder 3. A through hole 9 is provided in the center of the sliding plate 5 to ensure normal water flow during normal use of the drain pipe 1. The height of the ice deposits is much lower than the lowest point of the through hole 9, reducing the likelihood of the ice deposits crossing the through hole 9 and entering deeper parts of the drain pipe 1 when the sliding plate 5 pushes them. Furthermore, the drain pipe 1 is typically inclined at a certain angle, allowing water to flow out of the drain pipe 1 by gravity, thereby reducing water residue. This design also increases the difficulty for ice deposits to enter deeper parts of the drain pipe 1.

[0024] Reference Appendix Figure 3 , 4 A crushing component, capable of breaking up ice and dirt on the inner wall of the drain pipe 1, is fixedly connected to the connecting rod 7. The crushing component is a crushing rod 6, and several crushing rods 6 are fixedly connected to the connecting rod 7, with the ends of the crushing rods 6 located close to the inner wall of the drain pipe 1. When the operating cylinder 3 is turned, the operating cylinder 3 can drive the crushing rods 6 to rotate synchronously, thereby breaking up the ice and dirt.

[0025] Reference Appendix Figure 4 A removable sealing plug 4 is threaded onto the end of the operating cylinder 3 away from the drain pipe 1. When the cold storage is not used for a long time, the sealing plug 4 can be used to seal the drain pipe 1 to reduce the entry of dust.

[0026] The principle of this utility model

[0027] Reference Appendix Figure 1 , 2 The sealing plug 4 blocks the open end of the operating cylinder 3, sealing the entire drain pipe 1. This is suitable for situations where the cold storage is not in operation for a long time, reducing the impact of external dust on the drain end of the drain pipe 1. When the cold storage is operating normally, simply unscrew the sealing plug 4 to connect the drain pipe 1 to the outside.

[0028] Reference Appendix Figure 3 , 4 When there is a thick layer of ice deposits on the inner wall of drain pipe 1, it needs to be cleaned to prevent blockage. First, start the electric heating tape 2 normally to preheat the inner wall of the operating cylinder 3; or unscrew the sealing plug 4 and inject some warm water into the drain end of drain pipe 1 through the operating cylinder 3. When the ice deposits have initially melted (no need to wait for them to completely melt), the operating cylinder 3 can be turned directly. The operating cylinder 3 will slowly rotate and separate from the threaded cylinder 8 on drain pipe 1. During this process, the operating cylinder 3 drives the crushing rod 6 to rotate synchronously through the connecting rod 7. The rotation of the crushing rod 6 breaks up the initially melted ice deposits. At the same time, after the operating cylinder 3 separates from the threaded cylinder 8, the operating cylinder 3 drives the sliding plate 5 and scraper 10 to pull away from drain pipe 1, which can clean the ice deposits on the inner wall of drain pipe 1 after they have been initially broken up, and remove drain pipe 1. The whole operation process is quick and convenient. After the ice deposits have initially melted, the operating cylinder 3 directly drives the scraper 10 and crushing rod 6, which have been pre-placed in drain pipe 1, to move, thereby quickly and efficiently breaking up and pushing out the ice deposits.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
