The present utility model is described in detail below in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] A liquid clarity detection pretreatment device comprises a closed device and a pretreatment mechanism arranged in the closed device, wherein:

[0048] A closed device, wherein an input pipe and an output pipe are respectively connected along two opposite side walls thereof;

[0049] The pretreatment mechanism comprises a plurality of pretreatment baffles 1 arranged at intervals along the direction from the input pipeline to the output pipeline, wherein the vertical height of the pretreatment baffles 1 gradually increases and then gradually decreases along the direction from the input pipeline to the output pipeline;

[0050] An input pipeline, which includes a collection pipeline 2, a liquid inflow pipeline 3 and a flushing pipeline 4, wherein one end of the collection pipeline 2 is connected to the side wall of the closed device, and the other end is connected to the liquid inflow pipeline 3 and the flushing pipeline 4 through a multi-way pipe fitting;

[0051] The output pipe includes a liquid outflow pipe 5 and an emptying pipe 6. The liquid outflow pipe 5 is connected to the lower part of the side wall of the closed device, and the emptying pipe 6 is connected to the upper part of the side wall of the closed device.

[0052] Taking Example 1 as an example, the number of pretreatment baffles 1 is three, namely baffle 1, baffle 2, and baffle 3. Baffle 1 is set at 1 / 4 of the device and is half the height of the device; baffle 2 is set in the middle of the device and is 3 / 4 of the device; baffle 3 is set at 3 / 4 of the device and is half the height of the device. The pretreatment device includes: a closed device housing, baffle 1, baffle 2, baffle 3, an emptying valve, an emptying pipe, a liquid inflow pipe, a liquid inflow valve, a water inlet pipe, a water inlet valve, a collection pipe, a collection valve, a cover plate, and cover plate fixing screws.

[0053] Working principle of the pretreatment device: the liquid to be tested flows in from the liquid inlet pipe 3, the liquid inlet valve 10 controls the liquid flow rate and flow, and then flows into the closed device housing 7 through the summary pipe 2, and the summary valve 9 controls the liquid flow rate and flow. When the device needs to be flushed, open the water inlet valve 11 to allow water (usually drinking water or purified water) to flow into the device to flush the device structure. Baffles 1, 2, and 3 are provided in the closed device housing 7. When the liquid flows into the device, in the process of the liquid impacting and crossing the pretreatment baffle, bubbles and foam are eliminated in large quantities and the liquid flow rate is slowed down, reducing the impact on subsequent detection. When too much liquid flows into the device, it will be emptied through the emptying pipe 6. A cover plate 8 is provided on the top of the device, and the cover plate 8 is fixed to the top of the closed device housing 7 by the cover plate fixing screws. When the liquid flows through the device, the cover plate 8 or the operating port on the cover plate can be opened to view the internal conditions of the device (foam amount, material deposition, device corrosion, etc.).

[0054] After adding this pretreatment device, the foam content of the liquid flowing into the clarity detector is greatly reduced, from a thick layer that could not measure the clarity data to almost invisible to the naked eye. At the same time, the flow rate is smoother, ensuring the accuracy of the measured data;

[0055] After adding the pretreatment device, the pH value measurement accuracy is improved by 50%, and the measurement fluctuation range is reduced from the original ±30% to ±10%, thereby improving product quality.

[0056] The pretreatment device solves the technical problems such as a large number of bubbles and foams generated by high-speed flowing liquids, which affect the inspection of liquid clarity; large data fluctuations and low accuracy during liquid clarity inspection, which affect product quality.

[0057] Furthermore, in this embodiment, it can also be considered that the sealed device includes a sealed device housing 7 and a cover plate 8 installed on the top of the sealed device housing 7, and the sealed device in the sealed device housing has no gaps, and liquid will not drip when flowing through the device.

[0058] Furthermore, in this embodiment, it can also be considered that the collecting pipe 2 is connected to the lower part of the side wall of the closed device shell 7, the liquid outflow pipe 5 is connected to the lower part of the side wall of the closed device shell 7, and the emptying pipe 6 is connected to the upper part of the side wall of the closed device shell 7.

[0059] Furthermore, in the present embodiment, it is also possible to consider that a summarizing valve 9 is provided on the summarizing pipe 2, a liquid inlet valve 10 is provided on the liquid inlet pipe 3, a water inlet valve 11 is provided on the flushing pipe 4, a clarity detection point is provided on the liquid outflow pipe 5, a clarity detector is provided at the clarity detection point, and an emptying valve 12 is provided on the emptying pipe 6.

[0060] By setting up flushing pipes and water inlet valves, pipelines and devices can be flushed regularly to avoid crystallization in pipelines and devices, thus reducing measurement errors.

[0061] By setting liquid inlet valves and summary valves, the mechanical impact of liquid on the device at high flow rates is reduced, thereby increasing the life of the device. Taking the properties of the liquid into consideration, the pipes, valves, and device materials used are all corrosion-resistant materials. However, due to the design position and usage of the summary valve and the water inlet valve, plastic materials can be selected based on cost considerations.

[0062] Furthermore, in this embodiment, it can also be considered that the diameter of the emptying pipe 6 is twice the diameter of the liquid inlet, liquid outflow, and collecting pipes, and the diameter of the emptying pipe is twice the diameter of the inlet, outflow, and collecting pipes, which is easy to discharge overflow.

[0063] Furthermore, in this embodiment, it can also be considered that the pre-treatment baffle 1 is a thick plate material perpendicular to the bottom wall of the enclosure of the closed device.

[0064] Furthermore, in this embodiment, it can also be considered that the left, right and bottom sides of the pretreatment baffle 1 are correspondingly connected to the left, right and bottom inner walls of the closed device shell 7, or the bottom side of the pretreatment baffle 1 is connected to the bottom inner wall of the closed device shell 7.

[0065] Embodiment 2:

[0066] Embodiment 2 of the present invention is further improved on the basis of embodiment 1 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0067] For example, the side of the pretreatment baffle 1 facing the input pipe is a vertical surface or a slope surface, and the slope surface is a plane slope 13 or a concave-convex surface slope 14 evenly distributed with rib-shaped protrusions or a concave-convex surface slope 14 evenly distributed with semi-cylindrical protrusions.

[0068] Furthermore, in this embodiment, it can also be considered that the side of the pretreatment baffle 1 facing the output pipe is a vertical surface or a slope surface, and the slope surface is a plane slope 13 or a concave-convex surface slope 14 evenly distributed with rib-like protrusions or a concave-convex surface slope 14 evenly distributed with semi-cylindrical protrusions.

[0069] Case 1: The side of the pretreatment baffle 1 facing the input pipe is a vertical surface, and the side facing the output pipe is a vertical surface. As shown in Example 1, after the liquid impacts the front side of the pretreatment baffle, it passes over the pretreatment baffle and flows down along the back side of the pretreatment baffle. In the process of the liquid impacting and passing over the pretreatment baffle and in the process of the liquid flowing down, bubbles and foams are eliminated in large quantities and the liquid flow rate is slowed down, reducing the impact on subsequent detection. The vertical front side can directly face the liquid impact, and the bubbles and foams can be broken by strong mechanical impact. After the liquid flows down along the vertical back side, the bubbles and foams are eliminated again.

[0070] Case 2: The side of the pretreatment baffle 1 facing the input pipe is a vertical surface, and the side facing the output pipe is a slope surface. After the liquid impacts the front of the pretreatment baffle, it passes over the pretreatment baffle and flows down along the back of the pretreatment baffle. In the process of the liquid impacting and passing over the pretreatment baffle and in the process of the liquid flowing down, bubbles and foams are eliminated in large quantities and the liquid flow rate is slowed down, reducing the impact on subsequent detection. The vertical front side can directly face the liquid impact, and the bubbles and foams can be broken by strong mechanical impact. The liquid flows down the slope surface, which is conducive to slowing down the liquid flow rate, especially the concave and convex slope, which can not only slow down the liquid flow rate but also intercept some material deposition.

[0071] Case 3: The side of the pretreatment baffle 1 facing the input pipe is a sloped surface, and the side facing the output pipe is a vertical surface. After the liquid impacts the front of the pretreatment baffle, it passes over the pretreatment baffle and flows down along the back of the pretreatment baffle. In the process of the liquid impacting and passing over the pretreatment baffle and in the process of the liquid flowing down, bubbles and foams are eliminated in large quantities and the liquid flow rate is slowed down, reducing the impact on subsequent detection. The front side of the slope can also withstand liquid impact, and the bubbles and foams are broken by strong mechanical impact, especially the concave and convex slope, which can not only use strong mechanical impact to break the bubbles and foams but also intercept some material deposition. The liquid flows down along the vertical back side and eliminates the bubbles and foams again.

[0072] Case 4: The side of the pretreatment baffle 1 facing the input pipe is a sloped surface, and the side facing the output pipe is a sloped surface. After the liquid impacts the front of the pretreatment baffle, it passes over the pretreatment baffle and flows down along the back of the pretreatment baffle. In the process of the liquid impacting and passing over the pretreatment baffle and in the process of the liquid flowing down, bubbles and foams are eliminated in large quantities and the liquid flow rate is slowed down, reducing the impact on subsequent detection. The front side of the slope can also withstand liquid impact, and the bubbles and foams are broken by strong mechanical impact, especially the concave and convex slope, which can not only use strong mechanical impact to break the bubbles and foams but also intercept the deposition of some substances. The liquid flowing down the slope is conducive to slowing down the liquid flow rate, especially the concave and convex slope, which can not only slow down the liquid flow rate but also intercept the deposition of some substances.

[0073] Furthermore, in the above embodiment, it can be considered that the other two opposite side walls of the closed device housing 7 are respectively provided with observation windows 15, and a transparent observation window is sealed on the observation window 15. The staff can view the internal conditions of the device (foam quantity, material deposition, device corrosion, etc.) in real time through the transparent observation window.

[0074] Furthermore, in the above embodiments, it can also be considered that a large-diameter operating port 16 is provided on the cover plate 8, and a large-diameter sealing cover 17 is threadedly connected to the large-diameter operating port 16. The staff can check the internal conditions of the device (foam quantity, material deposition conditions, device corrosion conditions, etc.) by opening the operating port on the cover plate.

[0075] Embodiment 3:

[0076] Embodiment 3 of the present utility model is further improved on the basis of Embodiment 1 or 2 so as to give full play to the technical advantages of the present invention, which is described below by way of example.

[0077] For example, a small-diameter operating port 18 is further provided on the cover plate, a small-diameter sealing cover 19 is threadedly connected to the small-diameter operating port 18, and the small-diameter operating port 18 avoids the position where the pre-treatment baffle is located.

[0078] Furthermore, in this embodiment, it can be considered that the small-diameter cover 19 is equipped with a defoaming auger 20 and a defoaming motor 21 for driving the defoaming auger to rotate, and the defoaming auger 20 includes an auger shaft, an auger blade, and mesh holes opened on the auger blade. On the basis of the pre-treatment baffle defoaming, a rotating defoaming auger can be added to defoam, and the foam is broken by stirring to reduce the chance of foam formation. The contact area between the auger blade and the liquid is greater than the contact area of ​​the conventional stirring blade, thereby improving the efficiency of defoaming.

[0079] Furthermore, it can also be considered in Example 2 that the diameter of the auger blade gradually decreases from top to bottom.

[0080] Furthermore, in this embodiment, it can be considered that the small-diameter cover can also be equipped with an ultrasonic defoaming generator to use ultrasonic vibration to break the foam and improve the efficiency of eliminating the foam.

[0081] The above embodiments describe the present invention in detail, but the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of application of the present invention shall still fall within the scope of the patent coverage of the present invention.
