Description

Technical Field

[0001] This utility model relates to a filter pipeline assembly for a dew point detector. Background Technology

[0002] In industries such as metallurgy, chemical engineering, and heat treatment, precise measurement of the dew point of gases within industrial furnaces is often required to monitor and control production processes. However, these furnace gases frequently contain large amounts of impurities such as dust, oil mist, moisture, and even corrosive chemicals. If these impurities directly enter a precision dew point detector, they can contaminate or even permanently damage the sensor, leading to distorted measurements, shortened equipment lifespan, and ultimately affecting production quality and safety.

[0003] To protect dew point detectors, the common practice is to install filters on their sampling lines. Existing filters often employ simple filter cartridge structures, which have the following significant drawbacks: 1) Poor liquid handling capacity: While conventional filters can intercept some liquid contaminants, they lack effective liquid separation and collection mechanisms. Intercepted droplets easily accumulate inside the filter cartridge or at the bottom of the housing, increasing airflow resistance, saturating the cartridge and causing premature failure, and posing a risk of being re-entrained into downstream pipelines by high-speed airflow, failing to fundamentally reduce the protective pressure on the downstream detector; 2) Inconvenient maintenance and replacement: Filter cartridges, as consumables, require regular replacement. Existing filters typically use threaded tightening or complex bolt capping methods to fix the cartridges, making disassembly cumbersome, time-consuming, and labor-intensive, increasing the difficulty and time cost of equipment maintenance; 3) Insufficient integration and reliability: Existing filtration and drainage functions are often pieced together from independent components, resulting in numerous connection points and a risk of leakage. Furthermore, the connection method between the filter assembly and the detector is limited, offering poor installation flexibility and making it difficult to adapt to the complex and ever-changing installation needs of industrial sites.

[0004] Therefore, there is an urgent need for a filter piping assembly that integrates high-efficiency filtration, reliable liquid separation, and convenient maintenance and installation to solve the aforementioned problems in the existing technology. Utility Model Content

[0005] This invention provides a filter pipeline assembly for a dew point detector, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows: A filter piping assembly for a dew point detector includes a filter mechanism for filtering gases inside a furnace. The filter mechanism includes a housing, an external liquid storage device that corresponds to and communicates with a filter element disposed inside the housing, thereby collecting the liquid intercepted by the filter element to reduce the burden on subsequent filtration stages. The filter element has locking rods at its upper and lower ends, which engage with mounting openings formed on the inner wall of the housing for quick installation of the filter element.

[0007] The beneficial effects of this utility model are: (1) By connecting the external liquid storage component with the housing of the filter mechanism, this utility model can efficiently collect and separate liquid pollutants intercepted by the filter component, effectively avoid liquid retention or secondary entry into the airflow, and significantly reduce the burden on the downstream filtration and detection units. At the same time, the filter component can be quickly disassembled and assembled by the snap-fit ​​of the clamp rod and the mounting port, which greatly improves the convenience of filter element replacement and overall maintenance, thereby improving the operational reliability and maintenance efficiency of the dew point detector while ensuring the filtration effect.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0015] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0016] Reference Figure 1-4 As shown, a filter pipeline assembly for a dew point detector includes a filter mechanism 20 for filtering gas inside a furnace. The filter mechanism 20 includes a housing 200, and a liquid storage element 40 is provided on the outside of the housing 200, which is connected to the filter element 202 located inside the housing 200, thereby collecting the liquid intercepted by the filter element 202 to reduce the burden on subsequent filtration. The filter element 202 is provided with a locking rod 2026 at its upper and lower ends, and the locking rod 2026 engages with the mounting port 210 formed on the inner wall of the housing 200 to quickly install the filter element 202.

[0017] Specifically, the mounting port 210 is a circular channel. During installation, the locking rod 2026 is aligned with the vertical inlet of the channel, inserted, and then the filter element 202 is rotated at a certain angle (e.g., 90°) to allow the locking rod 2026 to slide into the horizontal locking part of the channel, thereby achieving axial and radial fixation. Preferably, the locking part is provided with an elastic protrusion or spring steel ball (not shown in the figure). When the locking rod 2026 is rotated into place, it will fall into a recess, providing tactile and audible feedback and preventing the filter element from loosening under vibration. This greatly simplifies the filter element replacement process, saves maintenance time, and reduces the skill requirements of operators, making it particularly suitable for use in situations requiring frequent maintenance or in confined spaces.

[0018] The filter element 202 includes a primary filter element 2020, a secondary filter element 2022, and a tertiary filter element 2024 arranged sequentially; the primary filter element 2020 is a sintered metal filter element or a ceramic filter element; the secondary filter element 2022 is a polymer membrane filter element or a condensation filter element; and the tertiary filter element 2024 is an activated carbon filter element.

[0019] Furthermore, the primary filter element 2020 primarily performs coarse filtration, intercepting larger particles and droplets. Its high structural strength allows it to support subsequent filter elements. The secondary filter element 2022 performs fine filtration, separating micron- and submicron-sized oil mist and moisture, using a coagulation effect to aggregate small droplets into larger ones. The tertiary filter element 2024 performs chemical filtration, adsorbing corrosive chemical molecules and odors from the gas. These three elements form a complete protective chain, from physical to chemical filtration and from coarse to fine filtration, each performing its specific function, significantly extending the lifespan of the high-precision and expensive dew point sensor at the downstream end. The bottom of the liquid storage component 40 is provided with an outlet 400 for discharging impurities, and both ends of the liquid storage component 40 are provided with T-shaped connectors 402; the outer wall of the housing 200 is symmetrically provided with outer plates 206, and T-shaped grooves 208 are formed on the outer plates 206 for engaging with the T-shaped connectors 402.

[0020] Specifically, the bottom of the housing 200 has one or more flow guide holes, and the top of the liquid storage component 40 has a liquid inlet that mates with the flow guide holes. The flow guide holes and the liquid inlet are sealed with a sealing ring to ensure that liquid can only flow into the liquid storage component 40 from inside the housing and that there is no gas leakage. This separates the liquid storage space from the main airflow channel, effectively preventing the high-speed airflow from impacting and re-entraining the collected liquid, ensuring stable liquid collection. At the same time, the independent liquid storage component 40 can be designed to be larger than the bottom of the integrated housing 200, extending the interval between automatic or manual drainage. Furthermore, the liquid storage component 40 can be easily designed to be transparent or have a viewing window for direct observation of the liquid level. Also, disassembling the liquid storage component 40 for cleaning will not affect the seal of the main filter.

[0021] During installation, the T-shaped connector 402 at the upper end of the liquid storage component 40 is aligned with the inlet of the T-shaped groove 208 on the outer plate 206 of the housing 200 and pushed in vertically or horizontally. Then, it is slid into the locking position along the groove. A stop block can be provided at the end of the T-shaped groove 208 to prevent excessive sliding. This connection method can complete the installation and locking of the liquid storage component without any tools, realizing the modularity of the liquid storage component 40. It can be replaced individually after damage, and cleaning and maintenance are extremely convenient.

[0022] An arc-shaped retainer 30 is provided on the housing 200, and a slot 300 for connecting with the outer plate 206 is formed on the arc-shaped retainer 30. The shape of the slot 300 of the arc-shaped retainer 30 is adapted to the contour of the outer plate 206 of the housing 200, and it can be fixed to the outer plate 206 by means of buckles, bolts or clamps. The body of the arc-shaped retainer 30 has at least one mounting hole for connecting with the external support surface by bolts.

[0023] The filter mechanism 20 is connected to the detector 10 via a pipeline; end caps 204 are provided at both ends of the housing 200, and the two ends of the end caps 204 are provided with interfaces for connecting to the pipeline.

[0024] Working principle: When the gas to be tested flows through the multi-stage filter element 202 connected in series, it passes through coarse filtration, fine filtration and chemical filtration in sequence, effectively intercepting particulate matter, droplets, oil mist and corrosive gases; the intercepted liquid pollutants are separated from the filter material under the action of gravity and coagulation effect and flow through the guide hole at the bottom of the housing 200 into the external liquid storage unit 40 for temporary storage, and finally discharged periodically from the bottom output port 400, thereby realizing gas-liquid separation and reducing the burden on the downstream stage; at the same time, the entire component realizes convenient assembly and maintenance of the filtration, liquid collection and fixing functional modules through the snap-on rotation installation of the filter element, the quick connection of the T-shaped groove 208 of the liquid storage unit and the arc-shaped bracket 30 on the housing 200, and finally continuously provides clean and dry gas to be tested for the downstream dew point detector.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
