Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a pure water column particle protection device. Background Technology

[0002] Purification columns are laboratory consumables used to separate and purify specific substances (such as proteins, nucleic acids, and compounds), and are widely used in fields such as biochemistry, molecular biology, and organic chemistry. They achieve separation and purification by filling a specific stationary phase material with the target molecule's physical or chemical properties (such as charge, affinity, and molecular size) through selective adsorption and elution. Some purification columns include those with filters to remove particles; this design is very common in laboratory and industrial applications, primarily used to prevent particulate matter from entering the chromatographic column or purification medium, thus protecting the column and extending its lifespan.

[0003] A large-capacity purification column for a water purifier, disclosed in patent CN104888507B, includes an upper cap, a lower cap, purification column A, and purification column B. Purification column A and purification column B are respectively disposed between annular grooves a and c, and between annular grooves b and d. Both purification column A and purification column B consist of a first purification column, a connecting ring, and a second purification column connected sequentially. The upper cap has an inlet port connecting to the first purification column of purification column A, and an outlet port connecting to the first purification column of purification column B. The lower cap also has a water passage hole connecting the two cavities. The advantages of this invention are: compact structure, convenient and quick installation, no resin debris leakage, good filtration effect, and large processing capacity.

[0004] In the above scheme, although support ribs are set on the filter screen to enhance the stability of the screen, the pressure on different parts of the screen is different. The closer to the center of the screen, the greater the pressure, and the easier it is for the support ribs to deform, resulting in local deformation of the support ribs and reducing the support effect. Utility Model Content

[0005] The purpose of this invention is to provide a pure water column particle protection device that can solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pure water column particle protection device includes a protective frame and a protective net. The protective net is laid in the inner ring of the annular protective frame. The inner ring of the protective frame is also provided with several interlaced support ribs to fix the protective net. The support ribs divide the protective net into several protective units with gradually increasing net area from the center of the protective frame outward. The outer ring of the protective frame is uniformly distributed with limiting structures for installation.

[0008] In the pure water column particle protection device, the supporting ribs include horizontal and vertical ribs that are perpendicular to each other, and the horizontal and vertical ribs together form several rectangular protection units.

The first cell is located on the side away from the center of the protection frame, and the second cell is located on the side close to the center of the protection frame.

[0010] In the pure water column particle protection device, the protective net is provided with a number of diagonal ribs, which are distributed along the diagonal of the protective unit.

[0011] In the pure water column particle protection device, the supporting ribs include two perpendicular symmetrical ribs, which pass through the circle of the protective frame and are connected at both ends to the inner ring of the protective frame.

[0012] In the pure water column particle protection device, a triangular reinforcing rib is provided at the connection between the supporting rib and the inner ring of the protective frame.

[0013] In the pure water column particle protection device, the limiting structure includes a limiting ring and a limiting plate. The two limiting rings are circumferentially arranged on the outer ring of the protective frame, and the limiting plate is axially arranged between the two limiting rings.

[0014] In the pure water column particle protection device, one of the limiting rings has an installation clearance notch.

[0015] In the pure water column particle protection device, a stepped sealing structure is provided on the end face of the protective frame near the installation clearance notch.

[0016] In the pure water column particle protection device, the protective net is formed by vertically interwoven longitudinal and transverse wires to create square mesh openings with a side length of 0.33 mm.

[0017] The advantages of this utility model are:

[0018] By combining multiple technical features, a highly efficient, stable, and durable pure water column particle protection device is provided.

[0020] Figure 2 This is a schematic diagram of the axial structure of this utility model.

[0021] Figure 3 This is a cross-sectional structural diagram of the present invention.

[0022] In the diagram, the components are: protective frame 1, limiting structure 11, limiting ring 12, limiting plate 13, stepped sealing structure 14, installation clearance notch 15, protective net 2, first cell 21, second cell 22, supporting rib 3, horizontal rib 31, vertical rib 32, diagonal rib 33, symmetrical rib 34, and triangular reinforcing rib 35. Detailed Implementation

[0023] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0024] like Figures 1-3 As shown, the pure water column particle protection device includes a protective frame 1 and a protective net 2. The protective net 2 is laid in the inner ring of the annular protective frame 1. The inner ring of the protective frame 1 is also provided with a number of interlaced support ribs 3 to fix the protective net 2. The support ribs 3 divide the protective net 2 into a number of protective units with gradually increasing net area from the center of the protective frame 1 outward. The outer ring of the protective frame 1 is uniformly distributed with limiting structures 11 for installation.

[0025] The protective frame is designed in a ring shape, with the protective netting tightly integrated into the inner ring of the frame to ensure stable positioning of the netting within the entire frame. The netting is secured by supporting ribs to prevent loosening due to external forces or vibrations. The supporting ribs, arranged in a staggered pattern, divide the netting into multiple progressively larger protective units. This structure effectively distributes pressure and improves the overall stability of the netting. The netting can be precisely positioned and effectively supported according to actual needs, enhancing the protective effect, and the robust structure of the protective frame is suitable for long-term use.

[0026] In this embodiment, the support rib 3 includes horizontal ribs 31 and vertical ribs 32 that are perpendicular to each other, and the horizontal ribs 31 and vertical ribs 32 together form several rectangular protective units.

[0027] Through a precise staggered design, horizontal and vertical ribs intertwine to form a uniform and stable grid structure. Each rectangular unit acts as an independent protective unit, effectively distributing stress and preventing impact from external particles or water columns. The mutually perpendicular staggered structure enhances the load-bearing capacity and compressive strength of the protective net, improving its protective effect, especially in high-pressure or impact environments, maintaining structural integrity.

[0028] In this embodiment, the protective unit includes a first cell 21 with a larger enclosing area and a second cell 22 with a smaller enclosing area. The first cell 21 is located on the side away from the center of the protective frame 1, and the second cell 22 is located on the side close to the center of the protective frame 1.

[0029] The density of the support ribs determines the size of the cell. A higher density of support ribs in the central area, which is more prone to deformation, provides stronger support. In contrast, a higher density of support ribs closer to the protective frame in the edge area allows for fewer support ribs, ultimately resulting in a more uniform support effect for both the inner and outer cells.

[0030] In this embodiment, the protective net 2 is provided with a plurality of diagonal ribs 33, which are distributed along the diagonal of the protective unit.

[0031] The diagonal ribs are set along the diagonal of the protective unit, which not only increases the stability of the mesh, but also effectively disperses the external forces transmitted through the protective mesh, enhances the deformation resistance of the protective mesh, especially under high pressure environment, can prevent the protective mesh from deforming or breaking due to pressure concentration, and ensures stability under long-term use.

[0032] In this embodiment, the support rib 3 includes two perpendicular symmetrical ribs 34, which pass through the circle of the protective frame 1 and are connected at both ends to the inner ring of the protective frame 1.

[0033] The use of two perpendicular bracing ribs increases the strength of the protective netting and prevents excessive local stress on the supporting ribs. The bracing ribs pass through the circular shape of the protective frame and are fixed to the inner ring, ensuring that the supporting ribs are stably installed throughout the entire protective frame. This allows the protective netting to bear external pressure evenly and prevents deformation of the netting surface due to uneven support.

[0034] In this embodiment, a triangular reinforcing rib 35 is provided at the connection between the supporting rib 3 and the inner ring of the protective frame 1.

[0035] Triangular reinforcing ribs are installed at the connection between the support ribs and the inner ring. By utilizing the geometric characteristics of the triangular structure, pressure from different directions can be effectively dispersed, reducing the impact of a single stress point on the connection. This can greatly enhance the load-bearing capacity of the connection, avoid structural damage caused by uneven stress, and further improve the stability and durability of the entire protective device.

[0036] In this embodiment, the limiting structure 11 includes a limiting ring 12 and a limiting plate 13. The two limiting rings 12 are circumferentially arranged on the outer ring of the protective frame 1, and the limiting plate 13 is axially arranged between the two limiting rings 12.

[0037] The design of the limiting ring and limiting plate enables precise positioning of the protective device during installation. The limiting ring is fixed to the outer ring of the protective frame to ensure the stability of the device during installation; the limiting plate, through axial setting, ensures the overall support of the structure and prevents circumferential rotation after installation, guaranteeing the stability of the protective device during installation and effectively preventing displacement due to external forces during long-term use, ensuring that the device remains stable during operation.

[0038] In this embodiment, one of the limiting rings 12 has an installation clearance notch 15.

[0039] To facilitate installation and disassembly, clearance notches are provided on the limit ring, allowing for appropriate adjustments during installation or avoiding interference from obstacles. This enables easy installation and disassembly of the equipment in actual operation, while reducing damage or misoperation caused by improper installation.

[0040] In this embodiment, a stepped sealing structure 14 is provided on the end face of the protective frame 1 near the installation clearance notch 15.

[0041] The stepped seal structure is designed to prevent water, particulate matter, or other external debris from entering the protective device, especially on the side with the clearance notch. It ensures that the device remains sealed when not in use to prevent material leakage.

[0042] In this embodiment, the protective net 2 is formed by vertically interwoven longitudinal and transverse wires to create square mesh openings with a side length of 0.33 mm.

[0043] The square mesh, formed by the precise weaving of the wires, has a side length of 0.33 mm. This mesh size design is suitable for filtering smaller particles, effectively blocking water column particles, and ensuring smooth fluid flow, thereby improving the efficiency and filtration accuracy of the device.

[0044] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
