Description

Technical Field

[0001] This invention provides a maintainable analytical device, and particularly relates to a sulfate ion maintainable analytical device that is easy to assemble. Background Technology

[0002] Sulfate ion maintainable analyzers are key auxiliary devices used in sulfate ion detection processes to regulate fluid pressure, filter impurities, and handle oil mist. Their core function is to provide a fluid environment that meets the accuracy requirements of ion analyzers by stabilizing fluid pressure, purifying the fluid medium, and adjusting oil mist concentration, thus ensuring the accuracy and stability of analytical results. In existing technologies, such devices typically consist of independent filtration and pressure regulating components, oil mist treatment components, and multiple connecting pipes. The filtration and pressure regulating components are usually cylindrical structures with a single adjustment knob at the top, a pressure gauge fixed to the front by bolts, and threaded pipes connected to the bottom. The oil mist treatment components are also independent cylinders with uniform and indistinct adjustment knobs at the top, a flat side mounting plate with low contact with the cylinder, and a right-angle closed end at the bottom. The two components are connected by flanges or flexible hoses.

[0003] The existing device has significant shortcomings: First, the filter and pressure regulating components and the oil mist treatment components need to be assembled through multiple connectors, resulting in a loose overall structure, cumbersome assembly steps, and a tendency for fluid stability to be affected by connection gaps; second, the adjustment knobs of the oil mist components have no visual difference, making it easy to confuse their functions and increasing the risk of misoperation; third, the mounting plate and the cylinder are connected by a plane, resulting in a small contact area, making it easy to loosen after fixing, affecting the overall stability of the device; fourth, the pressure gauge needs to be fixed with bolts, which is time-consuming to install and disassemble, and has low maintenance efficiency; fifth, the right-angle design at the bottom of the oil mist components results in a narrow operating space, making it inconvenient for pipeline connection and maintenance operations, and the decentralized structure of the filter and pressure regulating components and the oil mist components increases the overall space occupied and has poor adaptability. Utility Model Content

[0004] To address the aforementioned problems, this application provides an easily assembled and maintainable sulfate ion analysis device, which solves the issues of cumbersome assembly, loose structure, easy operation confusion, unstable installation, inconvenient maintenance, and large space occupation of existing devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sulfate ion maintainable analysis device that is easy to assemble, including a left filter pressure regulating unit, a right oil mist unit, and a connecting block connecting the two.

[0006] The left filter pressure regulating unit is provided with a cylindrical left cylinder, with a multi-faceted prism-shaped pressure regulating knob fixed to the top of the left cylinder, a circular pressure gauge mounting cavity at the front, and a knurled drain knob screwed to the bottom.

[0007] The right oil mist unit is provided with a cylindrical right cylinder. A tall cylindrical first adjustment knob and a short cylindrical second adjustment knob are arranged side by side on the top of the right cylinder. A flat mounting plate with a circular mounting hole is fixed to one side.

[0008] The connecting block integrally connects the left cylinder and the right cylinder, and the connecting block has a through mounting hole.

[0009] Preferably, the pressure regulating knob is hexagonal prism-shaped with rounded edges.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1 and Figure 2As shown, an easy-to-assemble, maintainable sulfate ion analysis device includes a left filter pressure regulating unit 1, a right oil mist unit 2, and a connecting block 3 connecting the two. The left filter pressure regulating unit 1 has a cylindrical left cylinder 14, with a hexagonal prism-shaped pressure regulating knob 11 with rounded edges fixed to the top of the left cylinder 14. The front part has a circular pressure gauge mounting cavity 12 with an annular step on the inner wall for engaging the edge of a circular pressure gauge, and a knurled drain knob 13 screwed to the bottom. In this embodiment, the left cylinder 14 and the connecting block 3 are integrally formed. The pressure regulating knob 11 is threadedly fixed to the top center of the left cylinder 14. The pressure gauge mounting cavity 12 is recessed into the front surface of the left cylinder 14 and communicates with the internal flow channel. The knurled drain knob 13 is screwed into the internal threaded hole at the bottom of the left cylinder 14 via an external thread. From the implementation points, the integrally formed connection structure reduces assembly steps. The hexagonal prism-shaped pressure regulating knob 11, with its rounded edges, ensures the stability of the force during adjustment and avoids scratches during operation. The ring of the pressure gauge mounting cavity 12... The stepped design enables quick mounting and positioning of the pressure gauge without the need for additional fasteners. The knurled drain knob 13 increases friction for easy manual turning to drain fluid, simplifying the maintenance process. Its innovation lies in integrating assembly and maintenance requirements into the structural details. Through reasonable connection and position design, the various components work together to improve the efficiency of device assembly (reduced connecting parts), enhance operational safety (rounded corners, knurling), and improve maintenance convenience (quick disassembly and assembly of pressure gauges, manual drainage), effectively solving the problems of scattered components, cumbersome assembly, and inconvenient maintenance operations in traditional devices.

[0024] The right oil mist unit 2 is provided with a cylindrical right cylinder 24. The top of the right cylinder 24 is provided with a tall cylindrical first adjustment knob 21 and a short cylindrical second adjustment knob 22 side by side. A flat mounting plate 23 with a circular mounting hole is fixedly connected to one side and fits and conforms to the outer circumference of the right cylinder 24 (the connecting surface is arc-shaped). The bottom outer side of the right cylinder 24 is provided with a slope transition structure with an angle of 30° to 60° with the axis. The connecting block 3 integrally connects the left cylinder 14 and the right cylinder 24 and has a through mounting hole 31.

[0025] In this embodiment, the right cylinder 24 and the connecting block 3 are integrally formed. The first adjustment knob 21 and the second adjustment knob (22) are screwed vertically into the corresponding screw holes on the top of the right cylinder (24) and their axes are parallel. The mounting plate 23 is fixed to the arc-shaped side of the right cylinder 24 by welding. The axis of its circular mounting hole is perpendicular to the axis of the right cylinder 24. The inclined transition structure is located on the bottom of the right cylinder 24 away from the connecting block 3. The axis of the mounting through hole 31 of the connecting block 3 is consistent with the axis direction of the left and right cylinders. Key implementation points include: the first and second adjustment knobs 21 and 22, with different heights, achieve quick functional differentiation through their shape differences, avoiding operational confusion; the arc-shaped connecting surface of the mounting plate 23 completely fits the outer circumference of the right cylinder 24, increasing the contact area to improve installation stability; the circular mounting hole adapts to standard fasteners for quick fixing; the 30°~60° bottom slope transition structure reserves space for operation below, avoiding operational obstruction caused by right-angle structures; the through mounting hole 31 of the connecting block 3 allows the entire device to be fixed to the equipment bracket with bolts, and in conjunction with the integrated left and right cylinder connection structure, reduces assembly gaps. Innovation is reflected in the synergistic improvement of operational identification, installation stability, and space utilization through differentiated shape design (height knobs), optimized structural adaptability (arc-shaped mounting plate), space-reserved design (bottom slope), and integrated fixing structure (mounting through hole). This complements the left filter pressure regulating unit, jointly achieving comprehensive assembly convenience and operational reliability of the device, solving the problems of easy misoperation, loose installation, and unreasonable space occupation in traditional oil mist units.

[0026] In use, this device requires the following components: a circular pressure gauge (installed in the pressure gauge mounting cavity 12, positioned by an annular step and sealed with a sealing ring), corrosion-resistant connecting pipes (connected to the knurled drain knob 13 at the bottom of the left cylinder 14 and the internal flow channel, used to transport the sulfate-containing ion fluid to be analyzed), a standard bolt assembly (passing through the circular mounting hole of the mounting plate 23 and the mounting through hole 31 of the connecting block 3 to fix the device to the analytical equipment frame), and O-ring rubber seals (embedded at the interface of the internal flow channel between the left cylinder 14 and the right cylinder 24 to enhance sealing); wherein the left cylinder 14... The right cylinder 24 and connecting block 3 are made of 304 stainless steel (corrosion resistant and strength suitable for fluid pressure), the pressure regulating knob 11, the first adjusting knob 21, and the second adjusting knob 22 are made of ABS engineering plastic (lightweight and easy to process knurling / edges), the mounting plate 23 is made of Q235 steel plate (good welding performance, ensuring stable installation), and the knurled drain knob 13 is made of polytetrafluoroethylene (chemical corrosion resistant, suitable for fluid contact scenarios). Through the cooperation of the above-mentioned existing technology devices with this device, a complete sulfate ion analysis fluid control system is formed, realizing the synergistic functions of fluid pressure regulation, oil mist treatment, and stable transportation.

[0027] Specifically, during installation, firstly, using a Phillips screwdriver and standard bolts (as is available in the prior art), the circular mounting holes of the mounting plate 23 are fixed to the corresponding bolt holes on the equipment frame (the bolt specifications are adapted to the mounting hole diameter). Simultaneously, an Allen wrench is used to tighten the mounting through hole 31 of the connecting block 3 to the auxiliary support, ensuring the overall device is horizontally fixed. When connecting the pipeline, existing compression fittings are used to connect the pipeline of the fluid to be analyzed to the bottom flow channel interface of the left cylinder 14 (PTFE sealing tape is wrapped around the interface to enhance the seal). Then, existing quick-connect fittings are used to connect the output end of the right cylinder 24 to the downstream analytical instrument. When installing the pressure gauge, an existing radial pressure gauge (dial diameter adapted to the mounting cavity size) is embedded into the pressure gauge mounting cavity 12. After axial positioning via the annular step, the edges are secured with elastic retaining rings to prevent detachment. During use… First, rotate the pressure regulating knob 11 clockwise to the initial position to open the upstream valve. Then, slowly rotate the pressure regulating knob 11 counterclockwise and observe the pressure gauge reading until it reaches the set value. Next, adjust the oil mist concentration by rotating the tall cylindrical first regulating knob 21 and adjust the flow rate by rotating the short cylindrical second regulating knob 22, according to the oil mist requirements. During operation, the operating space provided by the inclined transition structure at the bottom of the right cylinder 24 is utilized to facilitate the use of a wrench to assist in fixing the pipeline. During maintenance, close the upstream valve, tighten the shut-off valve before the knurled drain knob 13 clockwise, and then turn the knurled drain knob 13 counterclockwise to drain the residual fluid. If disassembly is required, loosen the nut of the compression fitting to separate the pipeline. Through the combination of the above-mentioned existing technical means and the structure of this device, a complete process from installation and fixing to operation and maintenance is formed, ensuring that the solution can be implemented.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
