Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an online cleaning type Y-type filter device for biopharmaceutical applications. Background Technology

[0002] Water is an indispensable medium in industrial production processes, most commonly used as chilled water, cooling water, hot water, and wastewater. However, these liquid media used in industrial production often contain significant amounts of silt, rust, and particulate matter, which can easily cause blockages in pipes and valves, damage to pumps, and affect instrument accuracy. Therefore, filters used in fluid transmission pipelines act as gatekeepers for fluid media in industrial production. The most common type in industrial production is the Y-type filter, which not only effectively removes foreign objects and impurities from the fluid media, protecting equipment, but also ensures process stability and improves energy efficiency.

[0003] Existing Y-type filter devices are mostly traditional Y-type filter devices, requiring regular manual disassembly and cleaning during use. However, timely cleaning is difficult under continuous production conditions. Once the filter screen becomes clogged, the supply of media cannot meet the operating conditions, which can damage the production process or equipment. Moreover, disassembly and reassembly during shutdown cleaning not only require coordinating the cessation of fluid transport in the pipeline, affecting production efficiency, but also waste manpower in the entire coordination, disassembly, and cleaning process. Furthermore, the media in the pipelines before and after filter installation needs to be emptied during disassembly and cleaning, often resulting in the waste of a large amount of media. In addition, frequent disassembly and cleaning can accelerate the aging or damage of the filter device's seals and valve cover fastening bolts. These features present numerous defects and inconveniences.

[0004] Patent document CN212039295U discloses a filter that is easy to disassemble and clean, including a filter tube with connecting flanges at both ends and an installation tube at the top, which communicates with the filter tube. A movable cover is mounted on the top of the installation tube via a fixing assembly. A filter screen and a rotating shaft are disposed inside the installation tube, with the rotating shaft inside the filter screen. An actuator and a connecting frame are mounted on the rotating shaft, and a steel brush is mounted on the side of the connecting frame close to the filter screen. This invention utilizes liquid flow to drive the actuator to rotate, which in turn causes the rotating shaft to rotate the steel brush, thereby cleaning the inside of the filter screen and preventing filter pore blockage. The fixing assembly and fixing holes allow for quick disassembly of the filter for easy cleaning of the filter screen. However, because it requires disassembly and cleaning, the flow of fluid media in the pipeline must be stopped, affecting production efficiency. Utility Model Content

[0039] This utility model discloses an online cleaning type Y-type filter device for biopharmaceuticals. By setting a rotatable scraper and a rotary sewage discharge device inside the filter cylinder, impurities can be directly discharged through the rotary sewage discharge device after being cleaned by the scraper. There is no need to stop the supply of fluid medium in the pipeline, nor is there a need to disassemble the filter and fill the discharge pipeline with medium. This reduces labor costs while avoiding the interruption of fluid medium supply and discharge, as well as the shutdown of the production process and operating equipment.

[0040] According to the online cleaning type Y-type filter device for biopharmaceutical use provided by this utility model, such as Figure 1 As shown, the device includes a valve body 1, a valve cover 2, a filter cylinder 4, a rotary sewage discharge device 5, and a rotary cleaning scraper 10 for the filter cylinder. The filter cylinder 4 is disposed in the filter installation cavity of the valve body 1 and is fixed by the valve cover 2. The rotary cleaning scraper 10 for the filter cylinder 4 is disposed inside the filter cylinder 4. The rotary sewage discharge device 5 is rotatably mounted on the valve cover 2 and is fixedly connected to the rotary cleaning scraper 10 for the filter cylinder. The rotary cleaning scraper 10 for the filter cylinder 4 can rotate and clean the inner wall of the filter cylinder 4 under the drive of the rotary sewage discharge device 5, and impurities are discharged to the outside through the rotary sewage discharge device 5.

[0041] This invention enables online cleaning of the filter screen without shutting down or stopping the fluid medium during continuous production. In continuous production, it is only necessary to open the discharge ball valve 14 on the rotary sewage discharge device 5 and rotate the rotary sewage discharge device 5 to drive the filter screen rotating cleaning scraper 10 on the inner wall of the filter screen cylinder 4. This efficiently removes foreign matter and impurities adsorbed and blocked on the inner wall of the filter screen and carries them out through the discharge ball valve 14 via water flow.

The rotary sewage discharge device 5 is provided with threads on its exterior. The rotary nut clamping device 9 is located on the side of the rotary drive nut 8 away from the valve cover 2 and is screwed to the threads on the exterior of the rotary sewage discharge device 5. It is used to apply a preload to the rotary scraper disc sealing device 11 through the rotary drive nut 8, thereby achieving a seal between the inner side of the valve cover 2 and the rotary disc of the filter screen rotary cleaning scraper 10.

[0045] In a preferred embodiment, a rotating scraper disc sliding ball 12 is also included; the rotating scraper disc sliding ball 12 is disposed between the inner side of the valve cover 2 and the rotating disc of the filter screen rotating cleaning scraper 10, and between the outer side of the valve cover 2 and the rotating drive nut 8; through the rotating scraper disc sealing device 11 and the rotating scraper disc sliding ball 12, the resistance of the rotating cleaning process is reduced while ensuring the sealing performance, making the cleaning operation simple and convenient, which not only ensures the operating efficiency of the equipment but also effectively improves the work efficiency.

[0046] In a preferred embodiment, the filter screen rotating cleaning scraper 10 has an S-shaped structure, which is coaxially arranged with the rotating sewage discharge device 5.

[0047] In a preferred embodiment, the rotary sewage discharge device 5 has a hollow structure and is connected to the inside of the filter screen cylinder 4; a discharge ball valve 14 is provided at the outer end of the rotary sewage discharge device 5, through which impurities are discharged to the outside; a gasket 3 is provided between the valve body 1 and the valve cover 2; the valve body 1 and the valve cover 2 are fixedly connected by bolts 6 and nuts 7; the bolts 6 pass through the flange and valve cover 2 at the end of the valve body 1 in sequence, and are threadedly connected to the nuts 7.

[0048] Example 1

[0049] This embodiment provides an online cleaning type Y-type filter device for biopharmaceutical use, including a valve body 1, a valve cover 2, a gasket 3, a filter screen cylinder 4, a rotary sewage discharge device 5, a bolt 6, a nut 7, a rotary drive nut 8, a rotary nut clamping device 9, a rotary cleaning scraper 10, a rotary scraper disc sealing device 11, a rotary scraper disc sliding ball 12, a rotary nut groove 13, and a discharge ball valve 14.

[0050] In the Y-type filter that requires no disassembly for cleaning, the valve body 1 is the main load-bearing structure, containing a media inlet, a filter screen mounting cavity, and a media outlet. The valve cover 2 secures the filter screen cylinder 4, preventing positional changes during media flow and ensuring stable filtration. A gasket 3 is installed between the valve body 1 and the valve cover 2, and its seal is achieved through the tightening of bolts 6 and nuts 7. The filter screen cylinder 4 is installed within the filter cavity and primarily filters particulate impurities and foreign objects from the media. The bolts 6 and nuts 7 mainly connect and secure the valve body 1 and valve cover 2, while also pressing the gasket 3 to ensure a tight seal.

[0051] The rotary drain device 5 is installed at the center of the valve cover 2. A filter screen rotating cleaning scraper 10 is connected inside the valve body 1. The cleaning scraper is made of stainless steel, S-shaped, with beveled edges on both sides, and fits tightly against the inner wall of the filter screen. The rotating disk is integrally connected, with one scraper distributed every 90°. The S-shaped design aims to reduce resistance from blockages on the inner wall of the filter screen when the scraper rotates clockwise or counterclockwise. The rotary drain device 5 has four rotating nut slots 13 on the outside of the valve cover, one every 90°. Similar to keys on a shaft, these slots fix the rotating drive nut 8 and, when rotating, force drives the rotary drain device 5 to rotate. The outer end of the rotary drain device 5 is threaded. The rotating nut clamping device 9 locks the rotating drive nut 8 towards the filter screen and scraper via the threads, while simultaneously ensuring the rotating scraper rotating disk sealing device 11 adheres tightly to the scraper rotating disk and the inner surface of the valve cover 2 for a sealing effect. The rotating scraper disc sealing device 11, located on the inner side of the rotating scraper disc and valve cover, is made of a material with relatively high hardness and small deformation, with a smooth end face, achieving a sliding seal effect, similar to the mechanical seal of a pump. The sealing between the rotating sewage discharge device 5 and the opening of the valve cover 2 uses an elastic sealing ring with large deformation, achieving a sealing effect through compression deformation. The rotating scraper disc sliding balls 12 are located between the inner side of the scraper disc and the valve cover, and between the outer side of the valve cover and the rotating drive nut 8, respectively. Their main function is to reduce the friction and resistance generated by the sealing surface, scraper, and foreign objects during the rotating sewage discharge process. The discharge ball valve 14 is installed at the outermost end of the rotating sewage discharge device 5 via a threaded connection. The discharge ball valve 14 is designed as a large-diameter ball valve; it opens while the filter screen is being cleaned by rotation, allowing impurities and foreign objects scraped off the inner wall of the filter screen to be carried out of the filter screen cavity by the water flow through the discharge ball valve.

[0052] Working principle:

[0053] When a decrease in fluid pressure or flow rate is detected at the downstream end of the filter during operation, indicating filter blockage, a wrench can be used to tighten the rotary drive nut 8. The rotary drive nut 8, through the rotary nut slot 13, drives the rotary drain device 5 and the filter screen cleaning scraper 10 to rotate. Since the filter screen cleaning scraper 10 is in close contact with the inner wall of the filter screen, and both sides of the scraper have beveled edges, it can rotate either clockwise or counterclockwise. After rotating 360°, the discharge ball valve 14 is opened, allowing the dislodged impurities and foreign objects to be carried out of the filter screen cavity by the water flow. Simultaneously, the rotary drain device 5 continues to rotate until no impurities or foreign objects remain in the discharged medium, at which point the discharge ball valve 14 is closed. This utility model's non-disassembly cleaning Y-type filter device is simple to operate, has a significant cleaning effect, and improves both work efficiency and equipment operating efficiency as well as energy efficiency.
