Description

Technical Field

[0001] The utility model belongs to the field of gravity sedimentation observation equipment, and specifically relates to a mobile and adjustable water treatment gravity sedimentation process precision characterization equipment. Background Art

[0002] Gravity sedimentation is an important operation in the water treatment process. Specifically, it refers to the process of causing solid particles suspended in a fluid to sink and separate from the fluid under the action of gravity. Its principle is to rely on the effect of the earth's gravitational field and use the density difference between the dispersed phase and the continuous phase to cause relative movement and produce sedimentation.

[0003] Gravity sedimentation is a common solid-liquid separation measure and unit operation in various water treatment processes. It is an indispensable and effective means of achieving solid-liquid separation, and its performance directly affects the effectiveness and efficiency of subsequent water treatment. Simultaneously, the design of sedimentation structures, calculation of coagulant dosage, and commissioning of related treatment units all require extensive sedimentation experiments and evaluations. Therefore, evaluating the gravity sedimentation performance of particles and analyzing and studying the gravity sedimentation process in water treatment have practical basis and value.

[0004] The sedimentation column observation method is the most traditional and widely used method for studying gravity sedimentation processes in water plants, sewage treatment plants, and laboratories. The specific operation of the method is: take a container of a certain diameter and height as a sedimentation column, add an appropriate volume of suspended liquid into it, and observe the sedimentation behavior of the particles in it over time. For example, when studying the sedimentation performance of activated sludge, a measuring cylinder or measuring cup with a volume of one or several liters is often used. The activated sludge suspension is added to it and allowed to stand to observe the sedimentation process and changes in the solid-liquid interface. When studying the coagulation sedimentation performance, the influent water sample is usually placed in the sedimentation column to study the gravity sedimentation of the suspended matter and conduct coagulation sedimentation experiments, providing experimental data support for the addition of flocculants in actual sewage treatment.

[0005] In the aforementioned sedimentation column observation method, the judgment, comparison, and image data collection of the sedimentation process within the sedimentation column are generally performed visually or by video. Due to certain differences in auxiliary equipment and instrumentation, this method is prone to errors. For example, differences in photography between different experimenters, differences in photography angles and relative distances at different times, and differences between sedimentation columns can all cause errors. These errors, in turn, affect the precision and relative accuracy of the gravity sedimentation experimental characterization and analysis, affecting the characterization and analysis conclusions. Therefore, accurate observation or photography has a significant impact on sedimentation research, especially when using particle image velocimetry (PIV) and non-invasive image analysis (NIA) methods for observation and photography. The quality of the photographs or images captured will directly affect the measurement, analysis, characterization, and comparison of the settling particle velocity and morphology. Therefore, it is particularly important to precisely control the imaging and characterization conditions to obtain comparable sedimentation characterization images with uniform boundary conditions in the sedimentation column observation method.

[0006] Compared to the previously mentioned particle image velocimetry (PIV) and non-invasive image analysis (NIA) methods, mobile phones, with their rapidly evolving camera technology, high image quality, short capture times, and portability, make recording and observing water treatment sedimentation processes easier and more convenient. However, the angle and method of recording with mobile phones are relatively difficult to pin down, making it difficult to provide highly accurate and comparable image data, limiting their application in observations. Utility Model Content

[0007] To address these issues, the present invention provides a mobile and adjustable device for accurately characterizing the gravity sedimentation process in water treatment. This device enables standardized and batch-scale operation of gravity sedimentation experiments. Compared with traditional observation methods, this device reduces the errors caused by manual observation and photography, can meet the shooting angle requirements of different gravity sedimentation experiments, ensures high comparability of image data across experiments, and records changes in height data during gravity sedimentation. Furthermore, the device features a simple structure, easy operation, and low maintenance costs, making it suitable for large-scale deployment.

[0008] Specifically, the utility model provides a mobile and adjustable water treatment gravity sedimentation process precision characterization equipment, which is characterized by including: a sedimentation column for accommodating the suspended liquid to be tested; a sedimentation support plate for supporting the sedimentation column; a shooting bracket for supporting the shooting equipment; a shooting lifting column for adjusting the height of the shooting bracket; a shooting support plate for supporting the shooting lifting column; and a telescopic connecting piece for telescopically connecting the sedimentation support plate and the shooting support plate.

[0009] The mobile and adjustable water treatment gravity sedimentation process precision characterization equipment provided by the present invention can also include: a sedimentation background plate, which is vertically fixed on the sedimentation support plate, and a vertically arranged scale is provided on the surface of the sedimentation background plate facing the sedimentation column, which is used as a size ruler during the shooting process.

[0010] Furthermore, the above-mentioned movable and adjustable water treatment gravity sedimentation process precise characterization equipment can also include: a sedimentation fixing part, which is used to fix the sedimentation column and the sedimentation background plate. The sedimentation fixing part is in the shape of a "convex" character, with one end being a rectangular ring part that is sleeved on the sedimentation background plate, and the other end being a circular ring part that is sleeved on the sedimentation column.

[0011] In addition, the above-mentioned mobile and adjustable water treatment gravity sedimentation process precise characterization equipment can also have such a technical feature, wherein the minimum scale point of the scale is flush with the bottom of the sedimentation column, and the maximum scale point is flush with the top of the sedimentation background plate.

[0012] The mobile and adjustable water treatment gravity sedimentation process precise characterization equipment of the present invention can also include: a lifting and fixing part, wherein the shooting lifting column is provided with multiple groups of lifting holes arranged in the vertical direction, the shooting bracket is mounted on the shooting lifting column, and is provided with a support arm connecting hole, and the lifting and fixing part passes through the support arm connecting hole and the lifting hole, thereby fixing the shooting bracket at different heights.

[0013] Furthermore, the above-mentioned movable and adjustable water treatment gravity sedimentation process precise characterization equipment may also have such a technical feature, wherein the length of the lifting fixture is twice the width of the shooting lifting column.

[0014] The above-mentioned movable and adjustable water treatment gravity sedimentation process precise characterization device may also have such a technical feature, wherein the shooting bracket also has a handle for the user to hold.

[0015] In addition, the mobile and adjustable water treatment gravity sedimentation process precise characterization equipment of the present invention may also have such technical features, wherein, the two side edges of the sedimentation support plate are provided with sedimentation telescopic connection holes extending along the length direction, and the two side edges of the shooting support plate are provided with shooting telescopic connection holes extending along the length direction. The number of telescopic connecting parts is two, one end of which is fixedly connected in the sedimentation telescopic connection hole, and the other end is fixedly connected in the shooting telescopic connection hole.

[0016] Function and effect of utility model

[0017] According to the mobile and adjustable water treatment gravity sedimentation process precision characterization device provided by the utility model, since the sedimentation support plate supports the sedimentation column that contains the suspended liquid, the shooting support plate supports the shooting lifting column that can adjust the height of the shooting support, and the telescopic connector telescopically connects the sedimentation support plate and the shooting support plate, the distance between the sedimentation column and the shooting device can be adjusted. Moreover, since the shooting lifting column can adjust the height of the shooting support, the height position of the shooting device can also be adjusted. Thus, the characterization device of the utility model can achieve the adjustment of the height of the shooting device and the distance between it and the sedimentation column. On the one hand, it can meet the specific shooting requirements of different experiments. On the other hand, it can also ensure that the height and distance do not change during the same experiment, ensuring the comparability of the corresponding captured image data. In different experiments, it is also possible to reduce various subjective human errors by setting the aforementioned height and distance to be consistent. In addition, since the overall support structure of the device is composed of the shooting support plate and the sedimentation support plate, both of which only need to be placed on the ground or a table to achieve their support function, the entire device is movable, easy to move and store, and thus convenient for conducting experiments in different locations.

[0018] In the present invention, since a scale is provided on the shooting background board, the scale can be used to provide sedimentation-related height data in the gravity sedimentation experiment, which is conducive to the collection and recording of multiple data such as the solid-liquid level change rate, the height of the clarified layer, and the height of the sludge layer in the gravity sedimentation experiment.

[0019] Furthermore, since the subsidence fixture can fix the subsidence column to the subsidence background plate, the position of the subsidence column can be determined. Moreover, this fixation can also ensure that the distance between the scale and the subsidence column remains consistent, thereby reducing the error caused by the change in the scale distance.

[0020] Since the shooting lifting column is provided with multiple groups of lifting holes arranged in the vertical direction, the shooting bracket is provided with arm connecting holes, and the lifting fixing parts pass through the arm connecting holes and the lifting holes to fix the shooting bracket at different heights, the shooting lifting column has a simple structure and can change the fixed height of the shooting bracket through simple operations.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.

[0028] <Example>

[0029] Figure 1 It is a structural schematic diagram of a mobile and adjustable water treatment gravity sedimentation process precision characterization device according to an embodiment of the present utility model.

[0030] like Figure 1 As shown, this embodiment provides a mobile and adjustable water treatment gravity sedimentation process precision characterization device (hereinafter referred to as the characterization device) 100, which includes a sedimentation column 1, a sedimentation support plate 2, a sedimentation background plate 3, a shooting support plate 4, a shooting lifting column 5, a shooting bracket 6 and a telescopic connecting part 7.

[0031] The sedimentation column 1 is a hollow cylindrical component with a bottom made of transparent material, and is used to contain the suspended liquid to be tested.

[0032] Figure 2 It is a structural diagram of the settlement support plate of an embodiment of the present utility model.

[0033] like Figure 1-2 As shown, the subsidence support plate 2 is used to support the subsidence column 1. The subsidence support plate 2 is a rectangular flat plate. Near one short side edge, a long strip groove is provided as a background plate mounting groove 21. Both long sides are provided with holes extending along the length direction. These holes serve as subsidence telescopic connection holes 22. Their depth is half of the long side edge, and they are used to connect the telescopic connector 7.

[0034] The subsidence background plate 3 is a rectangular opaque white flat plate-shaped component, the shape and size of its end portion matches the background plate mounting groove 21 , and the end portion is used to be inserted into the background plate mounting groove 21 , thereby vertically fixing the subsidence background plate 3 on the subsidence support plate 2 .

[0035] In this embodiment, Figure 1 As shown, the characterization device 100 also includes a sedimentation fixing member 8 for fixing the sedimentation column 1 to the sedimentation background plate 3. The sedimentation fixing member 8 is in the shape of a "convex" character, with a rectangular ring portion at one end and a circular ring portion at the other end; the inner surface size of the rectangular ring portion matches the outer surface size of the sedimentation background plate 3 and is sleeved on the sedimentation background plate 3, and the inner surface size of the circular ring portion matches the outer surface size of the sedimentation column 1 and is sleeved on the sedimentation column 1, thereby fixing the sedimentation background plate 3 to the sedimentation column 1. The surface of the sedimentation background plate 3 of the present embodiment facing the sedimentation column 1 is also provided with a vertically arranged scale, which is used as a size scale during the shooting process, and the minimum scale point of the scale is flush with the bottom of the sedimentation column 1, and the maximum scale point is flush with the top of the sedimentation background plate 3.

[0036] Figure 3 It is a structural diagram of a shooting support plate according to an embodiment of the present utility model.

[0037] like Figure 1 、 3 As shown, the shooting support plate 4 is used to support the shooting lifting column 5. The shooting support plate 4 is a flat plate with a square groove 41 in the center, which serves as the lifting column mounting groove. The two side edges are provided with shooting telescopic connection holes 42 extending along the length of the edge. The depth of the shooting telescopic connection holes 42 is half the length of the side edge and is used to connect to the telescopic connector 7.

[0038] like Figure 1 As shown, the shooting lifting column 5 is used to adjust the height of the shooting bracket 6. This shooting lifting column 5 is a square hollow cylindrical column, with a height equal to that of the subsidence background plate 3. Its surface is provided with multiple groups of lifting holes 51 arranged in a vertical direction. Each group of lifting holes 51 consists of four lifting holes, one on each of the four sides of the shooting lifting column 5. The centers of the four lifting holes 51 in a group are located on the same horizontal plane, and the centers of all lifting holes 51 on the same side are located on the vertical centerline of that side.

[0039] Figure 4 It is a structural diagram of a shooting bracket according to an embodiment of the present utility model.

[0040] like Figure 1 、 4 As shown, the shooting bracket 6 is used to support the shooting equipment. It is mounted on the shooting lifting column 5 and is generally in the shape of a square frame. It includes a first arm 61 , a second arm 62 , a handle 63 and a fixing frame 64 .

[0041] The first arm 61 and the second arm 62 are disposed opposite each other, with their ends on the same side connected to a handle 63. Each arm 61 and the second arm 62 are provided with an arm connection hole 65. The centers of the two arm connection holes 65 are located on the same horizontal plane and are substantially located at the center of the square edge of the square frame shape of the camera bracket 6. Furthermore, in this embodiment, the arm connection holes 65 and the lifting hole 51 have the same diameter.

[0042] The cross-section of the handle 63 is an inverted "L" shape, comprising a horizontal plate-like portion and a vertical plate-like portion extending vertically downward from one end of the horizontal plate-like portion, wherein the other end of the horizontal plate-like portion is simultaneously connected to the ends of the first arm 61 and the second arm 62, and the lower end of the vertical plate-like portion is provided with a slightly enlarged grip-like structure for ease of user holding.

[0043] The two ends of the fixing frame 64 are respectively connected to the other side ends of the first arm 61 and the second arm 62, and are used to fix mobile phones and other shooting equipment. Its specific fixing structure can refer to the existing technology (such as the mobile phone holder of the existing technology) and will not be repeated here.

[0044] like Figure 1 As shown, the characterization device 100 of this embodiment further includes a lifting fixture 9. This cylindrical component has a diameter substantially the same as, or slightly smaller than, the diameters of the support arm connection hole 65 and the lifting hole 51, and a length approximately twice the width of the shooting lifting column 5. To secure the shooting bracket 6 at different heights, the shooting bracket 6 is simply mounted on the shooting lifting column 5 and the lifting fixture 9 is inserted through the support arm connection hole 65 and the lifting hole 51 at the corresponding height.

[0045] The telescopic connector 7 is used to telescopically connect the subsidence support plate 2 and the shooting support plate 4, thereby simultaneously adjusting the distance between them. In this embodiment, the telescopic connector 7 is a multi-section telescopic rod, two in number, one end of which is fixedly connected to the subsidence telescopic connection hole 22 and the other end is fixedly connected to the shooting telescopic connection hole 42. The subsidence support plate 2 and the shooting support plate 4 have substantially the same width. Therefore, after connection, the two telescopic connectors 7 are substantially parallel to each other and can be extended and retracted synchronously to adjust the distance between the subsidence support plate 2 and the shooting support plate 4.

[0046] The following describes the use process of the characterization device 100 of this embodiment with reference to the accompanying drawings.

[0047] Before use, first determine the distance parameter between the shooting device and the sedimentation column 1 based on the shooting parameters of the shooting device, such as a mobile phone, and the parameters required for the experiment. Adjust the length of the telescopic connector 7 according to the distance parameter to adjust the distance between the sedimentation support plate 2 and the shooting support plate 4 to an appropriate distance, and place the sedimentation support plate 2 and the shooting support plate 4 on the ground or on the experimental platform. Then, turn the fixing frame 64 toward the direction of the sedimentation column 1, fix the shooting device on the fixing frame 64, hold the handle 63, adjust the shooting bracket 6 to an appropriate height, and use the lifting fixture 9 to pass through the support arm connection hole 65 and the lifting hole 51 of the corresponding height. Then, the suspension used for the gravity sedimentation experiment can be added to the sedimentation column 1, and the sedimentation process can be recorded using the shooting device. During the entire sedimentation process, the height of the shooting device and the distance between it and the sedimentation column 1 do not change. In the next experiment, you only need to remove the sedimentation column 1 from the sedimentation fixture 8 and pour out the suspension, then put it back into the sedimentation fixture 8 after cleaning, and you can still use the height of the shooting device and the distance between it and the sedimentation column 1 of the previous experiment; that is, during multiple consecutive experiments, the height and distance of the shooting device can remain unchanged, thereby ensuring consistency during multiple experiments.

[0048] In addition, when using a camera with a different shooting angle, the orientation angle of the fixing frame 64 can be changed. Specifically, the lifting fixture 9 can be passed through the support arm connection hole 65 and the lifting holes 51 on the other two opposite surfaces, so that the fixing frame 64 is not located on the surface facing the settlement column 1, but on a surface that forms a 90-degree angle with the surface facing the settlement column 1.
