Description

Technical Field

[0001] The invention relates to the technical field of water treatment agents, in particular to a device for testing the flocculation performance of a water treatment agent. Background Art

[0002] The main function of water treatment flocculants is to aggregate suspended particles and colloidal substances in water and form larger flocs through charge neutralization or bridging, which makes it easier to remove the flocs in subsequent sedimentation or transition steps. Therefore, water treatment agents are widely used in drinking water treatment, industrial wastewater treatment, and urban sewage treatment.

[0003] Since different water sources have different water quality characteristics, such as pH value, hardness, organic matter content, etc. These characteristics will affect the effect of flocculants, so it is necessary to determine the most suitable water treatment agent type and dosage by testing the flocculation performance of water treatment agents. Secondly, before the water treatment agents are put into mass production, the flocculation performance of the agents needs to be tested, so as to optimize the use process and treatment effect according to the test results during use.

[0004] At present, the common water treatment agent flocculation performance test methods include flocculation sedimentation rate test method, Zeta potential determination method, COD / BOD removal efficiency method, pH influence test method, etc. Among them, the most common is the flocculation sedimentation rate test method. The specific steps are to first take a certain amount of water sample to be treated, add different doses of flocculants, use an existing agitator, and stir rapidly at a set speed for a period of time (usually 1-3 minutes) to achieve sufficient mixing, and then stir slowly for several minutes (such as 5-20 minutes) to promote floc formation. After stopping stirring, the sedimentation rate is determined by recording the changes in the supernatant height at different time points, and the obtained sedimentation rate is used as an intuitive result of the agent flocculation performance.

[0005] The current testing process has the following problems: during the test, a certain amount of reagent is first added to the water sample, and the reagent and the water sample are stirred by a stirrer to mix the two. During this process, the reagent is added to the water sample from top to bottom, causing part of the water sample to mix and flocculate with the reagent, and affecting and delaying the subsequent reagent from gradually diffusing to the water sample below, resulting in poor overall mixing effect, affecting the authenticity and accuracy of the final test results.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] like Figure 1 and Figure 2 As shown, a water treatment agent flocculation performance testing device comprises: a measuring cylinder 1, a placing plate 2 is arranged on the upper side of the measuring cylinder 1, a docking assembly 3 is arranged between the placing plate 2 and the measuring cylinder 1, and a feeding mechanism 4 is arranged on the placing plate 2.

[0037] like Figure 1 , Figure 2 , Figure 5 , Fig.10 and Fig.11 As shown, the unloading mechanism 4 includes a cylinder 40, and a cylinder 40 with a vertical axis is rotated and penetrated on the placing plate 2. A cylinder 41 with a number two is slidably arranged in the cylinder 40, and a cylinder 42 with a number three is slidably arranged in the cylinder 41. The lower ends of the cylinders 40, 41 and 42 are all fixedly sleeved with an annular plate 43 with a cavity inside. The cylinders 40, 41 and 42 are not connected to each other. Unloading cavities 430 are opened in the cylinders 40, 41 and 42, and the unloading cavities 430 are all connected to the cavities of the corresponding annular plates 43.

[0038] like Figure 1 , Figure 2 and Figure 7 As shown, a plurality of circumferentially distributed discharge pieces 431 are fixedly provided on the annular plate 43 through a connecting pipe, a plurality of circumferentially distributed discharge holes 432 are opened on the discharge piece 431, a feeding unit 44 is provided on the upper end surface of the placement plate 2, the feeding unit 44 includes a storage box 440 arranged above the placement plate 2, and a driving group 45 is provided on the placement plate 2, and the driving group 45 is used to drive the first cylinder 40 to rotate synchronously and adjust the rotation speed of the first cylinder 40.

[0039] like Figure 1 As shown, the lower end surface of the placement plate 2 is fixedly provided with a mounting plate 5 located on the left side of the measuring cylinder 1, and the right end surface of the mounting plate 5 is fixedly provided with a plurality of cameras 50 arranged equidistantly from top to bottom, and the cameras 50 are opposite to the scales on the measuring cylinder 1 (not shown in the figure).

[0040] During operation, firstly, three quantitative medicines are manually put into the storage box 440, and a certain amount of water sample is injected into the measuring cylinder 1, and the three quantitative medicines correspond to the first cylinder 40, the second cylinder 41 and the third cylinder 42 respectively. Then, the staff moves the placement plate 2 to the top of the measuring cylinder 1, and installs the placement plate 2, the first cylinder 40, the second cylinder 41 and the third cylinder 42 through the docking assembly 3. Finally, the first cylinder 40, the second cylinder 41 and the third cylinder 42 are all inserted into the water sample, and then the feeding unit 44 works to put the medicine The agent is transported to the first cylinder 40, the second cylinder 41 and the third cylinder 42 and gradually discharged into the water sample. At the same time, the driving group 45 works to drive the first cylinder 40, the second cylinder 41 and the third cylinder 42 to drive all the discharge parts 431 to rotate synchronously and quickly, and then the driving group 45 drives all the discharge parts 431 to rotate slowly. During the above two rotation processes, the agent is gradually discharged into the water sample and begins to merge with the water sample. At the same time, the discharge part 431 stirs the agent and the water sample to make the two fully mixed.

[0041] In the above process, the scale on the measuring cylinder 1 reflects the height of the clear liquid of the water sample inside it at all times, and the camera 50 takes multiple photos. The initial clear liquid height of the water sample and the clear liquid height of the water sample after flocculation by the agent are obtained based on the photos taken. The average sedimentation rate is obtained by the ratio of the above two height differences to the time required for the above sedimentation process, and the flocculation performance of the water treatment agent is reflected by this rate.

[0042] like Figure 7 As shown, the discharge piece 431 is circular, and a truncated cone-shaped guide groove 433 is formed on the circular end surface of the discharge piece 431 . The interior of the discharge piece 431 is a cavity, and the cavity is connected to the corresponding connecting pipe and the discharge hole 432 .

[0043] like Figure 7 As shown, the direction from the small diameter end to the large diameter end of the three guide grooves 433 corresponding to the same annular plate 43 is the same as the rotation direction of the annular plate 43 .

[0044] During operation, the medicine flows from the storage box 440 through the first cylinder 40, the second cylinder 41 and the third cylinder 42 to the corresponding annular plate 43, and flows through the connecting pipe on the annular plate 43 to the corresponding discharge piece 431, and finally is discharged into the water sample through the discharge hole 432 on the discharge piece 431, and gradually begins to mix with the water sample. In the above process, the flow velocity of the water sample at the large diameter end of the guide groove 433 is less than the flow velocity at the small diameter end of the guide groove 433, that is, an accelerated laminar flow is formed at the small diameter end of the guide groove 433, and the accelerated laminar flow and the large diameter end of the guide groove 433 are subjected to dynamic pressure in the opposite direction (because the discharge piece 431 rotates, the discharge The turbulence generated by the dynamic pressure generated between the discharge piece 431 and the water flow meets during the circumferential movement of the discharge piece 431, thereby performing a dynamic mixing movement, so that the medicine is gradually mixed with the water sample during the circumferential rotation of the discharge piece 431, and the water sample and the medicine in the measuring cylinder 1 are driven to be dynamically mixed. Secondly, in the process of the water flow passing through the guide groove 433, the medicine flowing out of the discharge hole 432 flows to various places in the water sample along with the water flow. In summary, stirring and dynamic mixing are achieved by the circumferential rotation of the discharge piece 431, and the stirring process also assists the mixing of the medicine and the water sample, thereby ensuring sufficient mixing between the medicine and the water sample.

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, a guide piece 434 is fixedly provided in the lowermost annular plate 43, and the guide piece 434 is a conical structure with its tip facing upward, and a guide piece 435 is fixedly provided in the remaining two annular plates 43, and the guide piece 435 is a frustum structure with its small end surface facing upward, the upper guide piece 435 is slidably mounted on the second cylinder 41, and the lower guide piece 435 is slidably mounted on the third cylinder 42.

[0046] During operation, when the reagent is transported from the first cylinder 40, the second cylinder 41 and the third cylinder 42 through the corresponding annular plate 43 to the corresponding discharge piece 431, the reagent is quickly transported to the discharge piece 431 through the inclined guide of the guide piece 1 434 and the guide piece 2 435, and finally transported to the water sample for mixing.

[0047] like Figure 1 , Figure 2 and Figure 8As shown, the driving group 45 includes an L-shaped frame 450, the upper end surface of the placement plate 2 is fixedly provided with the L-shaped frame 450, the lower end surface of the horizontal section of the L-shaped frame 450 is fixedly provided with a motor 451, the output end of the motor 451 is fixedly provided with a driving pile 452 with a vertical axis, the driving pile 452 is sleeved with a driving cylinder 453 that slides up and down, the driving cylinder 453 moves up and down and penetrates the placement plate 2, and the driving cylinder 453 is fixedly sleeved with two sleeves distributed up and down, and a plurality of sleeves are fixedly provided on the sleeves The push bars 454 are distributed circumferentially, and the number of the push bars 454 on the upper ring is less than that on the lower ring. A circular plate is fixedly provided on the No. 1 cylinder 40, and a plurality of circumferentially distributed matching bars 455 are fixedly provided on the circular plate. An adjustment plate 456 located above the ring is slidably provided on the right end surface of the vertical section of the L-shaped frame 450, and the driving cylinder 453 rotates and passes through the adjustment plate 456. A cylinder 457 is fixedly provided between the adjustment plate 456 and the horizontal section of the L-shaped frame 450.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the docking assembly 3 includes a docking groove 30, the lower end surface of the mounting plate 5 is provided with a docking groove 30, a docking tube 31 is fixedly provided at the bottom of the measuring cylinder 1, a docking plate 32 located below the mounting plate 5 is fixedly provided on the measuring cylinder 1, and the lower end surface of the lowermost annular plate 43 and the upper end surface of the docking plate 32 are fixedly provided with docking columns 33 with vertical axes, and the two docking columns 33 are respectively inserted into the docking groove 30 and the docking tube 31 to complete the plug-in installation process of the placement plate 2 and the unloading mechanism 4, forming a stable rectangular frame.

[0049] During operation, when installing the placement plate 2, in the process of manually moving the placement plate 2 downward, the two docking columns 33 are respectively inserted into the docking tube 31 and the docking groove 30, thereby completing the installation process of all cameras 50 on the left side, the installation process of the No. 1 tube 40, the No. 2 tube 41 and the No. 3 tube 42, and making the placement plate 2, the mounting plate 5 and the No. 1 tube 40 together form a fixed rectangular frame, thereby improving the stability in the subsequent mixing process and avoiding the occurrence of a cantilever beam structure that affects the mixing test process.

[0050] It should be noted that, in the initial state, the height of the push bar 454 on the lower ring corresponds to that of the matching bar 455. After the medicine is transported into the water sample, the motor 451 works to drive the driving pile 452 to rotate synchronously, and the driving pile 452 drives the driving cylinder 453 and the corresponding two rings to rotate synchronously. The ring drives the push bar 454 thereon to rotate synchronously. During the whole rotation process, the push bar 454 on the lower ring pushes the matching bar 455, so that the matching bar 455 drives the first cylinder 40, the second cylinder 41 and the third cylinder 42 to rotate, and the rapid stirring process continues for a period of time (usually 1-3 minutes). , then the motor 451 stops working, the cylinder 457 works to drive the adjustment plate 456 and the driving cylinder 453 to move downward synchronously, and the driving cylinder 453 drives the two rings to move downward synchronously, so that the pushing bar 454 on the upper ring moves downward to correspond to the height of the matching bar 455, and the motor 451 resumes operation, so that the matching bar 455 drives the No. 1 cylinder 40, the No. 2 cylinder 41 and the No. 3 cylinder 42 to rotate, and continues the slow stirring process for a period of time (usually 5-20 minutes) to promote the formation of flocs, ensure that the clear liquid height value obtained later is the result of the full mixing state of the reagent and the water sample, and improve the accuracy of the test results.

[0051] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 As shown, the feeding unit 44 also includes a No. 3 cavity 441, the material storage box 440 is fixedly arranged on the upper end surface of the placement plate 2, and the No. 3 cavity 441, the No. 2 cavity 442 and the No. 1 cavity 443 are sequentially opened in the material storage box 440 from left to right, and a sealing door (not shown in the figure) is arranged on the upper end surface of the material storage box 440, and a feeding ring 444 is rotatably sleeved on the No. 1 cylinder 40, the No. 2 cylinder 41 and the No. 3 cylinder 42, and a feeding cavity 445 is opened in the feeding ring 444, and the No. 2 cylinder 41, the No. 2 cylinder 41 and the No. 3 cylinder 42 are all provided with a feeding ring 444, and a feeding cavity 445 is opened in the feeding ring 444. The No. 3 cylinder 42 is penetrated by a feed hole 446 connected to the corresponding inner cavity, and the feed hole 446 is connected to the corresponding feed cavity 445. The No. 1 cavity 443 and the feed cavity 445 in the feed ring 444 corresponding to the No. 1 cylinder 40, the No. 2 cavity 442 and the feed cavity 445 in the feed ring 444 corresponding to the No. 2 cylinder 41, and the No. 3 cavity 441 and the feed cavity 445 in the feed ring 444 corresponding to the No. 3 cylinder 42 are all connected by a hose, and an existing air pump (not shown in the figure) is provided on the storage box 440.

[0052] Water treatment flocculating agents usually exist in two states: solid powder or granules and water samples. However, before use, the solid state also needs to be dissolved in water and then mixed into the water sample for use. The agents to be pumped into the water sample are manually placed into chamber No. 3 441, chamber No. 2 442 and chamber No. 1 443 respectively, and the dosage of the agents in the three chambers is controlled to be the same. Then, the sealing door is closed to close the storage box 440, and the storage box 440, the first cylinder 40, the second cylinder 41 and the third cylinder 42 are kept in a constant pressure state. When the agents are then added and mixed, the air pump works to pump gas into chamber No. 3 441, chamber No. 2 442 and chamber No. 1 443, and the pressure in the three chambers increases, so that the agents enter the feed chamber 445 of the feed ring 444 through the hose, and gradually enter the corresponding first cylinder 40, second cylinder 41 and third cylinder 42 through the feed hole 446.

[0053] like Fig. 9 and Fig.10 As shown, a fixed rod 46 with a vertical axis is fixedly provided on the placement plate 2, and three connecting frames 460 are sleeved on the fixed rod 46. The three connecting frames 460 correspond to the three feed rings 444 one by one and are fixedly connected. The two upper connecting frames 460 are slidably sleeved on the fixed rod 46 up and down, and the lowest connecting frame 460 is fixedly sleeved on the fixed rod 46.

[0054] like Figure 8 and Fig. 9 As shown, a transmission bar 1 461 is rotatably provided on the middle connecting frame 460, and a transmission bar 2 462 is rotatably provided on the remaining two connecting frames 460. The transmission bar 1 461 is rotatably connected to the transmission bar 2 462. A connecting ring 463 is rotatably sleeved on the first cylinder 40, the second cylinder 41 and the third cylinder 42. The connecting ring 463 is fixedly provided on the corresponding connecting frame 460. A lifting frame is fixedly provided on the uppermost connecting ring 463, and a multi-stage electric push rod 464 is fixedly provided between the lifting frame and the placing plate 2.

[0055] During operation, when placing the No. 1 cylinder 40, the No. 2 cylinder 41 and the No. 3 cylinder 42 into the measuring cylinder 1, the height of the No. 2 cylinder 41 and the No. 3 cylinder 42 is adjusted according to the height of the water sample in the measuring cylinder 1. The specific implementation process is as follows: the multi-stage electric push rod 464 works so that its telescopic end drives the lifting frame and the uppermost connecting ring 463 to move up and down synchronously, and through the cooperation between the transmission bar 1 461 and the transmission bar 2 462, the three connecting rings 463 always maintain the same distance between each other, and adjust the distance according to the height of the water sample liquid level to ensure that the three annular plates 43 are arranged equidistantly above and below the liquid surface, thereby ensuring that the agent can be evenly dispersed in the liquid surface, improving the mixing effect between the agent and the water sample, and avoiding the problem that the distance between two adjacent annular plates 43 is too close, resulting in too high agent content in some areas of the water sample, and the distance between two adjacent annular plates 43 is too far, resulting in too low agent content in some areas, which affects the test results.

[0056] like Figure 1 As shown, a cover plate 47 is movably sleeved on the first cylinder 40 and is located below the placement plate 2 . A spring 470 is fixedly arranged between the cover plate 47 and the placement plate 2 , and the upper end opening of the measuring cylinder 1 is blocked by the cover plate 47 .

[0057] During operation, in the process of placing the No. 1 cylinder 40, the No. 2 cylinder 41 and the No. 3 cylinder 42, the placement plate 2 moves downward so that the covering plate 47 contacts the upper end surface of the measuring cylinder 1. As the placement plate 2 continues to move downward, the spring 470 is compressed. The elastic force generated by the compression deformation of the spring 470 causes the covering plate 47 to press against the top of the measuring cylinder 1, thereby preventing the water sample and the medicine from splashing out of the measuring cylinder 1 during the subsequent stirring process, thereby ensuring the accuracy of the test results.
