Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for heparin sodium precipitation. Background Technology

[0002] Precipitation filtration is a crucial step in the production of heparin sodium.

[0003] Heparin sodium precipitation filtration devices typically employ a single filtration structure with a limited filtration area, resulting in low filtration efficiency and an inability to meet the demands of large-scale production. Furthermore, cleaning the filter often requires disassembling the entire device, a cumbersome and time-consuming process that increases maintenance costs and time. In addition, traditional heparin sodium precipitation filtration devices are inadequate in terms of sealing and protection. For example, critical components such as the feed inlet and discharge pipes lack effective sealing structures, allowing dust and impurities to enter and affecting filtration efficiency and product quality. Moreover, after prolonged use, the deterioration of sealing performance can lead to leaks and other safety hazards.

[0004] Therefore, in order to address this problem, this invention provides a filtration device for heparin sodium precipitation. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-4 A filtration device for heparin sodium precipitation mainly includes a fixed frame 1. Five filter ports 2 are evenly distributed on the side of the fixed frame 1. Each filter port 2 has a groove 201 on its inner wall for holding a filter screen 3. Fixed valves 4 are installed on the sides of these filter ports 2, and these valves are threaded to ensure a tight seal. A discharge pipe 5 is connected to the side of the fixed valve 4 for discharging the filtered material. One end of the discharge pipe 5 is also equipped with a protective cover 6, also threaded, to prevent leakage during non-operational periods. Furthermore, the fixed frame 1 has internal sliding rails, allowing a cleaning frame 7 to slide within it. A fixed fan unit 8 is installed on one side of the fixed frame 1 to provide airflow, and an exhaust pipe 9 connected to its top is inserted into the fixed frame 1, located above the cleaning frame 7, to promote internal air circulation. A feeding port 10 is also provided at the top of the fixed frame 1 for adding the material to be filtered. The result is that this device can effectively filter heparin sodium precipitation while offering ease of cleaning and maintenance.

[0023] The cleaning frame 7 features slide rail grooves 101 machined on both sides of its inner wall. These grooves match the slide seats 702 on both sides of the cleaning frame 7, allowing the cleaning frame 7 to slide smoothly. A separation screen 701 is installed at the bottom of the cleaning frame 7 for further filtration. As a result, the separation screen 701 can be easily cleaned or replaced by sliding the cleaning frame 7, improving the maintenance efficiency and filtration effect of the device.

[0024] The fixed frame 1 features a sealing door 102 on its front side. This sealing door 102 is rotatably connected to the fixed frame 1 via a hinge, facilitating easy opening and closing. The front of the sealing door 102 also has a pull groove 1021, allowing the operator to manually pull open the sealing door 102. The design of the sealing door 102 enables the operator to easily enter the fixed frame 1 for inspection, cleaning, or maintenance work, while ensuring a tight seal when not in operation.

[0025] In this design, each filter port 2 has a groove 201 machined inside. These grooves 201 match the edge of the filter screen 3, allowing the filter screen 3 to easily slide into and be secured within the filter port 2. This design makes the installation and replacement of the filter screen 3 simple and quick, improving work efficiency.

[0026] The protective cover 6 has a hinged screw-on handle 601 on its side, allowing users to easily open or close it by turning the handle. The screw-on handle 601 makes the operation of the protective cover 6 more convenient and ensures the sealing of the discharge pipe 5 when not in use.

[0027] The top of the feeding port 10 is movably connected to a cover 1001 to seal the feeding port 10 and prevent dust and impurities from entering. A cover handle 1002 is also designed on the top of the cover 1001 for easy opening and closing by the user. The design of the cover 1001 and cover handle 1002 not only ensures the cleanliness of the feeding port 10 but also improves operational convenience.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
