Description

Technical Field

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

[0002] The main function of water treatment flocculating agents is to aggregate suspended particles and colloidal substances in water through charge neutralization or bridging action to form larger flocs, which are convenient for removing the flocs in subsequent sedimentation or filtration steps. Therefore, water treatment agents are widely used in the fields of 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 the flocculant. Therefore, it is necessary to determine the most suitable type and dosage of water treatment agents by testing the flocculation performance of water treatment agents. Secondly, before the water treatment agent is mass-produced, it is necessary to detect the flocculation performance of the agent, so as to optimize the use process and treatment effect according to the test results during use.

[0004] Currently, common methods for testing the flocculation performance of water treatment agents include the flocculation sedimentation rate experiment method, the Zeta potential determination method, the COD / BOD removal efficiency method, the pH influence experiment method, etc. Among them, the most common one is the flocculation sedimentation rate experiment method. The specific steps are as follows: first, take a certain amount of water sample to be treated, add different doses of flocculant, use an existing stirrer, and stir rapidly at a set speed for a period of time (usually 1 - 3 minutes) to achieve full mixing, then stir slowly for several minutes (such as 5 - 20 minutes) to promote the formation of flocs. After stopping the stirring, determine the sedimentation rate by recording the change in the height of the supernatant at different time points, and use the obtained sedimentation rate as an intuitive result of the flocculation performance of the agent.

[0005] The current testing process has the following problems: during the test, a quantitative agent is first put into the water sample, and the agent and the water sample are stirred by a stirrer to mix them. In this process, the method of putting the agent into the water sample from top to bottom causes some water samples to be mixed and flocculated with the agent, which affects and delays the subsequent diffusion of the agent to the lower water samples, resulting in poor overall mixing effect and affecting the authenticity and accuracy of the final test results.

Detailed implementation manners

[0035] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand 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 departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] As Figure 1 and Figure 2 shown, a flocculation performance testing device for water treatment agents includes: a graduated cylinder 1, a placement plate 2 is arranged on the upper side of the graduated cylinder 1, a docking assembly 3 is jointly arranged between the placement plate 2 and the graduated cylinder 1, and a feeding mechanism 4 is arranged on the placement plate 2.

[0037] As Figure 1 , Figure 2 , Figure 5 , Figure 10 and Figure 11 shown, the feeding mechanism 4 includes a first cylinder 40, the first cylinder 40 with a vertical axis rotates through the placement plate 2, a second cylinder 41 is slidably arranged up and down in the first cylinder 40, a third cylinder 42 is slidably arranged up and down in the second cylinder 41, annular plates 43 with internal cavities are fixedly sleeved at the lower ends of the first cylinder 40, the second cylinder 41, and the third cylinder 42, the first cylinder 40, the second cylinder 41, and the third cylinder 42 are not communicated with each other, feeding cavities 430 are opened in the first cylinder 40, the second cylinder 41, and the third cylinder 42, and the feeding cavities 430 are communicated with the cavities of the corresponding annular plates 43.

[0038] As Figure 1 , Figure 2 and Figure 7 shown, a plurality of circumferentially distributed discharging members 431 are fixedly arranged on the annular plate 43 through connecting pipes, a plurality of circumferentially distributed discharging holes 432 are opened in the discharging members 431, a feeding unit 44 is arranged 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, a driving group 45 is arranged on the placement plate 2, and the first cylinder 40 is driven to rotate synchronously by the driving group 45 and the rotation speed of the first cylinder 40 is adjusted.

[0039] As Figure 1 shown, an installation plate 5 is fixedly arranged on the lower end surface of the placement plate 2 on the left side of the graduated cylinder 1, a plurality of cameras 50 are fixedly arranged on the right end surface of the installation plate 5 at equal intervals from top to bottom, and the cameras 50 are opposite to the scales (not shown in the figure) on the graduated cylinder 1.

[0040] During operation, first, three portions of quantitatively measured medicaments are manually put into the storage box 440, and a certain amount of water sample is injected into the measuring cylinder 1, such that the three portions of quantitatively measured medicaments respectively correspond to the first cylinder 40, the second cylinder 41, and the third cylinder 42. Then, the staff moves the placement plate 2 above the measuring cylinder 1, and installs and places 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. Then, the feeding unit 44 operates to convey the medicaments into the first cylinder 40, the second cylinder 41, and the third cylinder 42 and gradually discharge them into the water sample. At the same time, the driving group 45 operates to drive the first cylinder 40, the second cylinder 41, and the third cylinder 42 to drive all the discharging members 431 to rotate synchronously and rapidly. Then, the driving group 45 is used to make the above-mentioned three drive all the discharging members 431 to rotate slowly. During these two rotation processes, the medicaments are gradually discharged into the water sample and start to blend with the water sample. At the same time, the discharging members 431 stir the medicaments and the water sample to make the two fully mixed.

[0041] During the above process, the height of the clear liquid of the water sample inside is constantly reflected by the scale on the measuring cylinder 1. The camera 50 takes multiple photos, and based on the photos taken, the initial height of the clear liquid of the water sample and the height of the clear liquid of the water sample after flocculation by the medicament are obtained. The average sedimentation rate is obtained by the ratio of the difference between the above two heights to the time required for the above sedimentation process, and the flocculation performance of this water treatment medicament is reflected by this rate.

[0042] As Figure 7 shown, the discharging member 431 is circular, and a frustum-shaped diversion groove 433 is formed on the circular end face of the discharging member 431. The inside of the discharging member 431 is a cavity, and this cavity is connected to the corresponding connecting pipe and the discharging hole 432.

[0043] As Figure 7 shown, for the three diversion grooves 433 corresponding to the same annular plate 43, the orientation from the small-diameter end to the large-diameter end 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 placing 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. A driving cylinder 453 that slides up and down is sleeved on the driving pile 452. The driving cylinder 453 vertically penetrates the placing plate 2 up and down. Two collars distributed up and down are fixedly sleeved on the driving cylinder 453. A plurality of pushing strips 454 distributed circumferentially are fixedly provided on the collars. The number of pushing strips 454 on the upper collar is less than the number of pushing strips 454 on the lower collar. A circular plate is fixedly sleeved on the first cylinder 40. A plurality of cooperating strips 455 distributed circumferentially are fixedly provided on the circular plate. An adjusting plate 456 located above the collar is slidably arranged up and down on the right end surface of the vertical section of the L-shaped frame 450. The driving cylinder 453 rotatably penetrates the adjusting plate 456. A cylinder 457 is fixedly provided between the adjusting plate 456 and the horizontal section of the L-shaped frame 450.

[0048] As Figure 1 , Figure 2 and Figure 3 As shown, the docking assembly 3 includes a docking groove 30. The docking groove 30 is opened on the lower end surface of the mounting plate 5. A docking cylinder 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. Axially vertical docking columns 33 are fixedly provided on the lower end surface of the lowermost annular plate 43 and the upper end surface of the docking plate 32. The two docking columns 33 are respectively inserted into the docking groove 30 and the docking cylinder 31 to complete the plug-in installation process of the placing plate 2 and the blanking mechanism 4, forming a stable rectangular frame.

[0049] During operation, when installing the placing plate 2, during the process of manually moving the placing plate 2 downward, the two docking columns 33 are respectively clamped into the docking cylinder 31 and the docking groove 30, thereby completing the installation process of all the cameras 50 on the left side, the installation process of the first cylinder 40, the second cylinder 41 and the third cylinder 42, and enabling the placing plate 2, the mounting plate 5 and the first cylinder 40 to jointly form a fixed rectangular frame, improving the stability during the subsequent stirring process and avoiding the appearance of a cantilever beam structure that affects the stirring test process.

[0050] It should be noted that in the initial state, the height of the push bar 454 on the lower collar corresponds to that of the mating bar 455. After the reagent is delivered into the water sample, the motor 451 operates to drive the drive pile 452 to rotate synchronously. The drive pile 452 drives the drive cylinder 453 and the corresponding two collars to rotate synchronously. The collar drives the push bar 454 thereon to rotate synchronously. During the full-circle rotation of the push bar 454 on the lower collar, the mating bar 455 is pushed, causing the mating bar 455 to drive the first cylinder 40, the second cylinder 41, and the third cylinder 42 to rotate, and a rapid stirring process continues for a period of time (usually 1 - 3 minutes). After that, the motor 451 stops operating, and the cylinder 457 operates to drive the adjusting plate 456 and the drive cylinder 453 to move downward synchronously. The drive cylinder 453 drives the two collars to move downward synchronously, so that the height of the push bar 454 on the upper collar corresponds to that of the mating bar 455 after moving downward. The motor 451 resumes operation, causing the mating bar 455 to drive the first cylinder 40, the second cylinder 41, and the third cylinder 42 to rotate, and a slow stirring process continues for a period of time (usually 5 - 20 minutes) to promote floc formation, ensuring that the height value of the subsequent obtained clear liquid is the result under the state of full mixing of the reagent and the water sample, and improving the accuracy of the test results.

[0051] As Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown in ,

[0051] , Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 , the feeding unit 44 further includes a third chamber 441. The storage box 440 is fixedly arranged on the upper end surface of the placing plate 2. A third chamber 441, a second chamber 442, and a first chamber 443 are successively formed in the storage box 440 from left to right. A sealing door (not shown in the figure) is arranged on the upper end surface of the storage box 440. Feeding rings 444 are rotatably sleeved on the first cylinder 40, the second cylinder 41, and the third cylinder 42. A feeding cavity 445 is formed in the feeding ring 444. Feeding holes 446 communicating with their corresponding inner cavities are formed through the second cylinder 41, the second cylinder 41, and the third cylinder 42, and the feeding holes 446 communicate with the corresponding feeding cavities 445. A hose is provided between the first chamber 443 and the feeding cavity 445 in the feeding ring 444 corresponding to the first cylinder 40, between the second chamber 442 and the feeding cavity 445 in the feeding ring 444 corresponding to the second cylinder 41, and between the third chamber 441 and the feeding cavity 445 in the feeding ring 444 corresponding to the third cylinder 42. An existing air pump (not shown in the figure) is arranged 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. Manually put the agents to be pumped into the water sample into the third chamber 441, the second chamber 442, and the first chamber 443 respectively, and control the same dosage of the agents in the three chambers. Then close the sealing door to close the storage box 440, and make the interior of the storage box 440, the first cylinder 40, the second cylinder 41, and the third cylinder 42 in a constant pressure state. When carrying out the agent feeding and mixing operation afterwards, the air pump works to pump gas into the third chamber 441, the second chamber 442, and the first chamber 443. The pressure in the three chambers increases, so that the agent enters the feeding chamber 445 of the feeding ring 444 through the hose, and gradually enters the corresponding first cylinder 40, second cylinder 41, and third cylinder 42 through the feeding hole 446.

[0053] As Figure 9 and Figure 10 shown, a vertically axially fixed rod 46 is fixedly arranged on the placement plate 2. Three connecting frames 460 are sleeved on the fixed rod 46. The three connecting frames 460 respectively correspond to and are fixedly connected to the three feeding rings 444. The two upper connecting frames 460 are slidably sleeved on the fixed rod 46 up and down, and the lowermost connecting frame 460 is fixedly sleeved on the fixed rod 46.

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

[0055] During operation, when placing the first cylinder 40, the second cylinder 41, and the third cylinder 42 into the measuring cylinder 1, adjust the heights of the second cylinder 41 and the third cylinder 42 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 to drive the lifting frame and the uppermost connecting ring 463 to move up and down synchronously through its telescopic end. Through the cooperation between the first transmission bar 461 and the second transmission bars 462, the distances between the three connecting rings 463 are always kept the same, and the distances are adjusted according to the height of the water sample liquid level, ensuring that the three annular plates 43 are arranged equidistantly up and down in the liquid level, so as to ensure that the agent can be evenly dispersed into the liquid level, improve the mixing effect between the agent and the water sample, and avoid the problem that the distance between adjacent two annular plates 43 is too close, resulting in too high agent content in some areas of the water sample, and the distance between adjacent two annular plates 43 is too far, resulting in too low agent content in some areas and affecting the test results.

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

[0057] During operation, when the first cylinder 40, the second cylinder 41 and the third cylinder 42 are being placed, the placing plate 2 moves downward, causing the sealing cover plate 47 to contact the upper end face of the measuring cylinder 1. As the placing 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 sealing cover plate 47 to tightly press against the upper part of the measuring cylinder 1, preventing the water sample and the reagent from splashing out of the measuring cylinder 1 during the subsequent stirring process and ensuring the accuracy of the test results.
