Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of liquid medium sampling equipment, and specifically relates to a simple liquid medium sampling device. Background Technology
[0002] In the coal chemical industry, submersible analyzers are widely used for measuring liquid media due to their affordability and versatility. However, when it comes to measuring media flowing within pipelines, traditional general-purpose submersible analyzers reveal their limitations. Dedicated measuring instruments equipped with flow cells are required, which, while meeting the measurement needs, reduce equipment versatility and increase costs. Conversely, collecting large quantities of the medium in a container before using a general-purpose submersible probe, while utilizing existing equipment, presents numerous drawbacks.
[0003] Problems and shortcomings of existing technologies:
[0004] 1. When the medium is collected from the container and detected by the submersible probe, a significant time lag occurs, making it impossible to update the measurement data in real time;
[0005] 2. Impurities in the measurement medium can easily contaminate the probe, reducing its accuracy and sensitivity, increasing cleaning and maintenance work, increasing labor intensity, and shortening the probe's lifespan.
[0006] Existing technologies suffer from several problems: they not only significantly reduce the real-time accuracy of media sampling but also generate large amounts of waste liquid, increasing labor intensity and workload while failing to ensure the accuracy and real-time nature of measurement results. Consequently, they cannot efficiently meet the requirements for precise and timely measurement of pipeline flowing media in coal chemical production processes. Therefore, a simple liquid media sampling device is proposed. Utility Model Content

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, as Figure 1-3 As shown, a simple liquid medium sampling device includes a flow cell 1, which serves as the main body of the device and provides space for liquid flow and sampling. The flow cell 1 ensures the continuous and stable flow of the medium through overflow, and the measurement data is updated accurately in real time.
[0026] The flow cell 1 contains a measuring chamber 2, which holds the liquid to be measured, providing a stable measuring environment for the submersible probe and reducing external interference. An overflow port 3 is located on the middle side wall of the measuring chamber 2. The overflow port 3 adjusts the liquid level to prevent overflow, balances pressure to avoid localized liquid level fluctuations, and ensures stable probe measurement conditions.
[0027] The measuring chamber 2 is equipped with a filter screen 4, which intercepts impurity particles in the medium to prevent probe contamination. The bottom opening of the measuring chamber 2 is provided with a liquid inlet 5, which guides the medium in the pipeline into the measuring chamber 2 at a controllable flow rate. The bottom side of the flow tank 1 is provided with a drain outlet 6, which quickly discharges waste liquid and cleaning wastewater.
[0028] The specific design of the aforementioned key components will be discussed in detail below:
[0029] The flow chamber 1 is a DN100 stainless steel pipe with a height of 220mm. DN100 refers to a nominal diameter of 100mm and a total height of 220mm. Coal chemical media often contain acid or particulate matter, and the stainless steel material can resist corrosion and extend service life. The DN100 pipe diameter is compatible with standard industrial pipeline branch interfaces, facilitating direct connection, and the 220mm height provides sufficient liquid residence time to ensure that the probe fully contacts the medium.
[0030] The inlet 5 is a steel pipe with a diameter of Φ8, welded to one side of the flow-through tank 1 at a height of 60mm. The inlet 5 is welded to the side wall of the flow-through tank 1, with its centerline 60mm from the bottom of the tank. The Φ8 diameter balances the flow velocity and flow rate, preventing turbulence from causing liquid surface fluctuations. The 60mm height ensures that the liquid flows smoothly into the bottom of the measuring chamber 2, reducing the generation of air bubbles.
[0031] The measuring chamber 2 is located close to the inner wall of the flow cell 1, and is 30mm wide and made of stainless steel. It is formed by welding stainless steel plates, is 30mm wide, and its top is 20mm lower than the top of the flow cell 1.
[0032] Measurement chamber 2 is closely attached to the inner wall of flow cell 1, forming an independent cavity. The 30mm width restricts the lateral diffusion of the liquid, creating an approximate laminar flow state and reducing the interference of turbulence on probe measurement.
[0033] The top of the measuring chamber 2 is 20mm lower than the top of the flow pool 1, forming an overflow buffer zone. When the liquid level rises abnormally, excess liquid overflows into the flow pool 1 through the top gap.
[0034] The filter screen 4 is positioned above the liquid inlet 5. Filter screen 4 is made of 316 stainless steel woven mesh with a pore size of 0.5mm, and is fixed 10mm above the liquid inlet 5, covering the entire cross-section of the measuring chamber 2. Filter screen 4 effectively intercepts impurities in the medium, preventing probe contamination.
[0035] The overflow port 3 has a diameter of Φ10mm, and there are three overflow ports 3 evenly arranged. The overflow ports 3 are located 140mm from the bottom on the side wall of the measuring chamber 2. The three Φ10mm circular holes are evenly distributed on the same horizontal plane on the side wall of the measuring chamber 2, with 120° equal distribution around the circumference. The center line is 140mm from the bottom of the pool. The 140mm height is set as a fixed upper limit for the liquid level to ensure that the probe immersion depth is consistent. The typical immersion depth is 100-120mm. When the liquid level in the flow pool 1 rises to the height of the overflow port 3, automatic overflow can be achieved to ensure the consistency of the measurement. When the medium flow rate exceeds the discharge capacity of the conventional overflow port 3, secondary overflow can be achieved through the top of the measuring chamber 2 to avoid the medium overflowing the flow pool 1 and causing environmental pollution.
[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
