Description

Technical Field

[0001] The invention relates to the technical field of composite flocculant production, in particular to a dynamic sampling device used for composite flocculant production. Background Art

[0002] Composite flocculants are copolymers of two or more single-component flocculants formed through certain chemical reactions to form high molecular weight copolymers. Flocculation technology is an economical and simple water treatment method commonly used at home and abroad to improve water treatment efficiency. It is widely used in the treatment of industrial water, industrial wastewater and domestic sewage. When composite flocculants are produced, they need to be sampled and analyzed, and dynamic sampling is to regularly draw a certain number of samples for analysis as required when the equipment is in normal operation.

[0003] For example, the patent with publication number CN207667632U discloses a stirring device for flocculant production. The patent has a simple structure, is easy to operate, occupies little space when in use, and can effectively improve the production efficiency of flocculants. The setting of the uniformly distributed sampling tube allows workers to easily sample and test the mixed liquid at different positions in the reaction barrel. However, during the sampling process, the sampling tube valve is opened to allow the internal mixed liquid to flow out of the sampling tube for sampling. However, after the valve is closed, due to the narrow interior of the sampling tube, part of the mixed liquid will remain in its internal port, resulting in the problem that the residual mixed liquid will interfere with the sample during subsequent dynamic extraction, affecting the accuracy of subsequent sample detection.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a dynamic sampling device for composite flocculant production is proposed. Summary of the invention

Perforated plates are fixed inside both ends of the sampling box, and a limit frame is fixed on one side of the perforated plate, and the limit frame is slidably connected to the transmission rod.

[0010] Furthermore, a rotating assembly is provided at one end of the top of the base plate, and the rotating assembly includes a damping shaft, a limiting wheel and a limiting groove. The damping shaft is rotatably connected internally at one end of the base plate, and a limiting wheel is fixed to the outer side of the middle part of the damping shaft, and a limiting groove is opened on the outer side of the limiting wheel.

[0011] Furthermore, the rotating assembly also includes a rotating seat and a sliding column. The rotating seat is fixed to one side of the placement seat, and the sliding column is equidistantly arranged on one side of the rotating seat.

[0012] Furthermore, the limiting groove is Z-shaped, and the sliding column is slidably connected to the limiting wheel through the limiting groove.

[0013] Furthermore, the bottom of the damping shaft is connected to an adjustment component, and the adjustment component includes a rotating disk, a connecting plate and a driving rod.

[0016] The present invention provides a dynamic sampling device for composite flocculant production, which has the following beneficial effects:

[0017] 1. When the present invention is in use, the mounting base can be first fixed on the side wall of the stirring device so that the guide cover is located inside the device. Therefore, during the operation of the stirring device, the mixed liquid will rotate in the stirring tank. At this time, the guide cover can be used to guide the solution so that it enters the inside of the guide tube, passes through the inside of the sampling box, and then flows out from another guide tube, so that the solution in the guide tube will keep flowing, thereby achieving a dynamic update effect, avoiding poor fluidity of the solution in the guide tube, resulting in the accuracy of subsequent sampling being affected by solution residue during sampling, and through the arrangement of multiple sampling boxes, it is convenient to collect multiple samples during dynamic sampling, and the sampling box and the placement seat are connected by magnetic pins and mounting grooves, and the placement seat is adsorbed by the magnetic pins for rapid positioning, which is conducive to improving the convenience of disassembly and assembly of the sampling box.

[0018] 2. When the slide seat is squeezed, the slide seat will slide under the guidance of the limit sleeve, causing the compression spring to contract. At this time, the connecting rod will also drive the transmission rod to move under the guidance of the limit frame, so that the cover and the orifice plate can be separated. Therefore, during the sampling process, the mixed liquid can enter the sampling box through the gap formed between the cover and the orifice plate to sample and collect the mixed liquid, and when the slide seat is not squeezed, the compression spring will push the slide seat under the limitation of the sampling box and the limit rod, thereby pulling the transmission rod through the connecting rod to close the cover and the orifice plate. At this time, since the cover, orifice plate, sampling box, and two sides of the placement seat are flush, the end of the guide tube can be blocked and closed to achieve the effect of intercepting flow, and the sealing ring is used to improve the sealing effect of the end to prevent the solution from flowing out during the rotation of the placement seat.

[0019] 3. In the present invention, when the position of the sampling box needs to be changed, it is only necessary to drive the limiting wheel to rotate through the damping shaft. At this time, since the limiting groove will limit the sliding column, the limiting wheel will push the sliding column through the inclined part of the limiting groove during the rotation process, so that the rotating seat drives the placing seat to rotate one-sixth of a circle. Therefore, after adjustment, the position of the sampling box can be quickly aligned with the guide tube without careful observation and adjustment, which is beneficial to improving the convenience during operation. At the same time, after rotation, the sliding column will fit with the flat part of the limiting groove, and the flat part is relatively long, so the rotating seat can be positioned, which is beneficial to enhancing the stability after adjustment.

[0020] 4. When the damping shaft is operated, the rotating disk will also be driven to rotate at the same time, and the driving rod can be pushed through the connecting plate, so that the adjusting plate slides along the light rod, driving the limiting plate to move together. At this time, since the limiting plate will not block the end of the top rod, the reset spring will push the retaining ring to separate the top rod from the sliding seat, and the sampling box will be in a closed state. Therefore, before the placement seat rotates, the opening and closing assembly can be in a closed state to avoid interfering with the rotation of the placement seat. When the placement seat rotates and stops, the rotating disk will pull the driving rod through the connecting plate to reset the adjusting plate. At this time, the limiting plate will squeeze the top rod to push the sliding seat, so that the opening and closing assembly can be in an open state. Therefore, the opening and closing state of the opening and closing assembly can be automatically controlled during operation without additional adjustment, which is beneficial to reducing the operating steps and improving the convenience of sampling.

[0030] See also Figures 1 to 4The sampling box 405 is provided with an opening and closing assembly 5, which includes a limit sleeve 501, a slide 502 and a limit rod 503. The limit sleeve 501 is fixed to one side of the interior of the sampling box 405, and the limit sleeve 501 is slidably connected to the interior of the limit sleeve 501. The slide 502 is slidably connected to the limit rod 503, and the limit rod 503 is fixedly connected to the sampling box 405. The opening and closing assembly 5 also includes a compression spring 504, a connecting rod 505 and a transmission rod 506.

The opening and closing assembly 5 also includes a cover 507, a hole plate 508 and a limit frame 509. The end of the transmission rod 506 is connected with a cover 507, and the cover 507 is in a truncated cone shape. The two ends of the sampling box 405 are fixed with a hole plate 508, and a limit frame 509 is fixed on one side of the hole plate 508, and the limit frame 509 is slidably connected with the transmission rod 506;

[0031] The specific operation is as follows: first, the mounting seat 1 is fixed on the side wall of the stirring device so that the deflector 402 is located inside the device, and then the sampling box 405 is inserted into the placement groove on the placement seat 404, and the magnetic suction pin 407 is adsorbed on the placement seat 404, and the other end of the magnetic suction pin 407 is inserted into the mounting groove 406, so that the sampling box 405 can be quickly installed and fixed, and when the sliding seat 502 is squeezed during use, it will slide under the guidance of the limit sleeve 501, so that the compression spring 504 will shrink. At this time, the connecting rod 505 will also drive the transmission rod 506 to move under the guidance of the limit frame 509, so that the cover 507 can be separated from the orifice plate 508. Therefore, during the sampling process, the mixed liquid can enter the sampling box 405 through the gap formed between the cover 507 and the orifice plate 508. Later, when the stirring device is working, the mixed liquid will rotate in the stirring tank. At this time, the deflector 402 can be used to guide the solution 405, and then flows out from another flow guide tube 401, so that the solution in the flow guide tube 401 will keep flowing, achieving the effect of dynamic update, avoiding the poor fluidity of the solution in the flow guide tube 401, resulting in the residual solution during sampling affecting the accuracy of subsequent sampling, and after sampling, when the slide 502 is not squeezed, the compression spring 504 will push the slide 502 under the limit of the sampling box 405 and the limit rod 503, thereby pulling the transmission rod 506 through the connecting rod 505, so that the cover 507 and the orifice plate 508 are closed, at this time, because the cover 507, the orifice plate 508, the sampling box 405, and the placement seat 404 are flush on both sides, the end of the flow guide tube 401 can be blocked and closed to achieve the effect of interception, and the sealing ring 403 is used to improve the sealing effect of the end to avoid the solution from flowing out during the rotation of the placement seat 404.

[0032] See also Figures 5 to 7A rotating assembly 6 is provided at one end of the top of the bottom plate 2, and the rotating assembly 6 includes a damping shaft 601, a limiting wheel 602 and a limiting groove 603. The damping shaft 601 is rotatably connected inside one end of the bottom plate 2, and the limiting wheel 602 is fixed to the outer side of the middle part of the damping shaft 601, and the limiting groove 603 is provided on the outer side of the limiting wheel 602. The rotating assembly 6 also includes a rotating seat 604 and a sliding column 605. The rotating seat 604 is fixed to one side of the placement seat 404, and the sliding column 605 is equidistantly arranged on one side of the rotating seat 604. The limiting groove 603 is Z-shaped, and the sliding column 605 is slidably connected to the limiting wheel 602 through the limiting groove 603. The bottom of the damping shaft 601 is connected to an adjusting assembly 7, and the adjusting assembly 7 includes a rotating disk 701, a connecting plate 702 and a driving rod 703. The bottom of the damping shaft 601 is fixed to a rotating disk 701, and the rotating disk The bottom of 701 is rotatably connected with a connecting plate 702, and the bottom of the connecting plate 702 is rotatably connected with a driving rod 703. The adjusting assembly 7 also includes an adjusting plate 704, a light rod 705, a limiting plate 706 and a limiting seat 707. The bottom of the driving rod 703 is provided with an adjusting plate 704, and one end of the adjusting plate 704 is internally slidably connected with the light rod 705, and the light rod 705 is fixedly connected to the bottom plate 2. A limiting plate 706 is fixed to one side of the upper end of the adjusting plate 704, and the outer side of the limiting plate 706 is slidably connected to the limiting seat 707, and the limiting seat 707 is fixedly connected to the bottom plate 2. The adjusting assembly 7 also includes a push rod 708, a retaining ring 709 and a return spring 710. One end of the limiting seat 707 is internally slidably connected with the push rod 708, and a retaining ring 709 is fixed to the outer side of one end of the push rod 708, and a return spring 710 is arranged on one side of the retaining ring 709.

[0033] The specific operation is as follows: when the damping shaft 601 is rotated, the sliding column 605 will first slide on the flat part of the limiting groove 603. At this time, the damping shaft 601 will drive the rotating disk 701 to rotate at the same time, and the driving rod 703 can be pushed through the connecting plate 702 to make the adjustment plate 704 slide along the light rod 705, driving the limiting plate 706 to move together. At this time, since the limiting plate 706 will not block the end of the top rod 708, the return spring 710 will push the retaining ring 709 under the limit of the limiting seat 707, so that the top rod 708 is separated from the sliding seat 502, and the sampling box 405 will be in a closed state. Therefore, before the placement seat 404 rotates, the opening and closing component 5 can be closed to avoid interfering with the rotation of the placement seat 404, and when the inclined part of the upper limit groove 603 of the limiting wheel 602 is aligned with the sliding column 60 5, it will push the slide column 605, so that the rotating seat 604 drives the placement seat 404 to rotate one-sixth of a circle, so that after adjustment, the position of the sampling box 405 can be quickly aligned with the guide tube 401, without careful observation and adjustment, which is conducive to improving the convenience during operation. At the same time, after rotation, the slide column 605 will fit with the flat part of the limiting groove 603, and the flat part is relatively long. Therefore, when the placement seat 404 rotates and stops, the damping shaft 601 continues to rotate, and the rotating disk 701 will pull the driving rod 703 through the connecting plate 702 to reset the adjusting plate 704. At this time, the limiting plate 706 will squeeze the push rod 708 to push the slide seat 502, so that the opening and closing component 5 can be in an open state. Therefore, the opening and closing state of the opening and closing component 5 can be automatically controlled during operation.

[0034] In summary, when using the dynamic sampling device for composite flocculant production, first fix the mounting seat 1 on the side wall of the stirring device so that the guide cover 402 is located inside the device, and then insert the sampling box 405 into the placement groove on the placement seat 404, and make the magnetic pin 407 adsorb the placement seat 404, and the other end of the magnetic pin 407 will be inserted into the mounting groove 406, so that the sampling box 405 can be quickly installed and fixed. Secondly, when moving the sampling box 405 between the guide tubes 401, it is only necessary to drive the limiting wheel 602 to rotate through the damping shaft 601. Since the limiting groove 603 will limit the sliding column 605, the limiting wheel 602 will push the sliding column 605 through the inclined part of the limiting groove 603 during the rotation process. The rotating seat 604 drives the placing seat 404 to rotate, so it rotates equidistantly during rotation, so that after adjustment, the position of the sampling box 405 can be quickly aligned with the guide tube 401, and at the same time, after rotation, the sliding column 605 will fit with the flat part of the limiting groove 603, so the rotating seat 604 can be positioned. Then, after moving, the rotating disk 701 will pull the driving rod 703 through the connecting plate 702, so that the adjusting plate 704 drives the limiting plate 706 to move together, and at this time, the limiting plate 706 will squeeze the ejector rod 708 to push the sliding seat 502, and when the sliding seat 502 is squeezed, it will slide under the guidance of the limiting sleeve 501, so that the compression spring 504 will contract, and at this time, the connecting rod 505 will also drive the transmission rod 506 to the limiting frame 509, the cover 507 can be separated from the orifice plate 508. Therefore, during the sampling process, the mixed liquid can enter the sampling box 405 through the gap formed between the cover 507 and the orifice plate 508. Then, when the stirring device is started, the mixed liquid will rotate in the stirring tank. At this time, the guide cover 402 can be used to guide the solution to enter the guide tube 401, and then flow out from another guide tube 401 after passing through the sampling box 405, so that the solution in the guide tube 401 will continue to flow, avoiding the poor fluidity of the solution in the guide tube 401, resulting in the residual solution affecting the accuracy of subsequent sampling. Finally, when collecting the sample, the damping shaft 601 is rotated before the placement seat 404 rotates. By driving the rotating disk 701 to rotate at the same time, the driving rod 703 can be pushed through the connecting plate 702, so that the adjustment plate 704 slides along the light rod 705, driving the limit plate 706 to move together. At this time, since the limit plate 706 will not block the end of the top rod 708, the return spring 710 will push the retaining ring 709 under the limit of the limit seat 707, so that the top rod 708 is separated from the slide seat 502, and when the slide seat 502 is not squeezed, the compression spring 504 will push the slide seat 502 under the limit of the sampling box 405 and the limit rod 503, thereby pulling the transmission rod 506 through the connecting rod 505, so that the cover 507 and the orifice plate 508 are closed. At this time, since the cover 507, the orifice plate 508, the sampling box 405, and the two sides of the placement seat 404 are flush,Therefore, the end of the flow guide tube 401 can be blocked and sealed to achieve the effect of interception, and the sealing effect of the end can be improved by using the sealing ring 403 to prevent the solution from flowing out during the rotation of the placement seat 404. Therefore, the opening and closing state of the opening and closing component 5 can be automatically controlled during operation, thereby improving the convenience of sampling.
