Description

Technical Field

[0001] This utility model belongs to the field of breathing cap technology, specifically a new type of breathing cap that is resistant to CIP cleaning splashes. Background Technology

[0002] Breathing caps are widely used equipment accessories in pharmaceutical, food, and chemical industries, and are particularly crucial for aseptic filling and CIP (Clean-In-Place) systems in dairy production. CIP cleaning refers to a process where cleaning fluid is circulated into the equipment according to a pre-programmed sequence, following specific temperature, flow rate, and time parameters, to complete the cleaning and disinfection process without disassembling the production equipment. In dairy production, breathing caps are primarily used for ventilation and pressure balancing in storage tanks and pipelines, ensuring effective air removal and preventing negative pressure during CIP, while also blocking the entry of external contaminants.

[0003] After a period of use, storage tanks need to be cleaned inside. However, with existing traditional breathing caps, cleaning fluid can easily splash out through the cap, affecting the cleaning effect and potentially polluting the surrounding environment. In addition, some breathing caps have complex structures, making disassembly and cleaning inconvenient, increasing maintenance costs and time. Summary of the Invention

[0004] The purpose of this invention is to provide a novel breathing cap that prevents liquid splashing during CIP cleaning, while improving sealing and ease of disassembly, thereby increasing cleaning efficiency and reducing maintenance costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel CIP (Clean-In-Place) spray-resistant breathing cap is provided, comprising an outer shell. An annular groove is formed at the bottom of the outer shell, and a recess is formed on the outer wall of the annular groove. A rotating ring is fitted onto the outer wall of the annular groove. The rotating ring includes a meshing cavity and a hollow cavity. A toothed groove is formed on the inner wall of the meshing cavity, and an annular protrusion is provided on the inner wall of the hollow cavity. Multiple limiting grooves are formed on the outer wall of the outer shell. A screw is movably installed inside each of the multiple limiting grooves. The lower end of the screw penetrates the bottom of the outer shell and is fixedly connected to a gear. The outer wall of the gear meshes with the toothed groove. A positioning ring is fixedly connected to the outer wall of the screw, and the positioning ring is located inside the limiting groove. A protective cap is fitted on the top of the outer shell, and multiple limiting blocks are fixedly connected to the inner wall of the protective cap. Each limiting block is located inside its corresponding limiting groove, and the limiting block and its corresponding screw are threadedly connected.

[0006] Optionally, a sealing gasket is provided on the top of the housing, and the sealing gasket is made of polyurethane.

[0007] Optionally, the top of the outer shell is provided with a positioning hole, and there are multiple positioning holes. The top of the inner wall of the protective cap is fixedly connected with a positioning rod, and there are multiple positioning rods. The positioning rod is located inside the corresponding positioning hole.

[0008] Optionally, a filter membrane is installed inside the housing, and the bottom of the filter membrane is threadedly connected to the bottom of the housing.

[0009] Optionally, the bottom of the housing is provided with a connecting end, and the outer wall of the connecting end is threaded.

[0010] Optionally, a sealing groove is provided on the outer wall of the connecting end, and a sealing ring is installed inside the sealing groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes a linked structure consisting of a rotating ring, gears, a screw, a limiting block, and a protective cap. Rotating the rotating ring drives the gears and screw to rotate, causing the limiting block to move downwards along the limiting groove, thus opening and closing the protective cap. This makes cleaning and maintenance operations more convenient and efficient. The cooperation between the sealing gasket and the protective cap improves sealing performance, preventing liquid and vapor splashing during CIP cleaning and ensuring the cleanliness of the production environment. The filter membrane uses a detachable threaded connection, facilitating regular cleaning or replacement and ensuring long-term stable filtration. The connection end, combined with the sealing groove and sealing ring, forms a double sealing structure, enhancing the reliability of the connection under high-pressure conditions and avoiding leakage risks. The precise alignment of the positioning rod and positioning hole ensures the stability of the protective cap's movement, preventing misalignment or jamming. This invention prevents liquid splashing during cleaning, while improving sealing and ease of disassembly, thereby increasing cleaning efficiency and reducing maintenance costs.
