Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to a self-cleaning sodium hypochlorite dosing device for pipelines. Background Technology

[0002] Sodium hypochlorite is a broad-spectrum, highly effective, and environmentally friendly disinfectant. It has lower safety risks during storage, transportation, and use, stable bactericidal and inactivation effects, and readily available raw materials. It has gradually become the main water treatment disinfectant in the industry. Generally, when using it, sodium hypochlorite needs to be added into the water pipe through a dosing device.

[0003] However, sodium hypochlorite solution has poor stability and is easily decomposed by temperature and light. After evaporation, it is very easy to form dried crystals in the pipeline. The crystals will continue to accumulate and grow larger with the use of the solution, clogging the pipeline. However, the dosing device is usually an integrated device. The operator needs to stop the dosing device and disassemble the entire device for manual cleaning, which makes the cleaning too cumbersome and inconvenient for the operator. Utility Model Content

The bottom end of the push rod 61 is threadedly connected to a bearing rod 62. The bottom end of the bearing rod 62 is fixedly connected to a cleaning plate 63. Several release ports 64 are provided on the outer wall of the cleaning plate 63. The push rod 61 and the bearing rod 62 cooperate to control the up and down displacement of the cleaning plate 63.

[0035] A groove 65 is provided on the inner wall of the injection pipe 5, and a slider 66 is slidably connected in the groove 65. The slider 66 is fixedly connected to the side wall of the cleaning plate 63 to ensure the stability of the vertical displacement of the cleaning plate 63. A servo motor spindle is fixedly connected to the top shaft end of the push rod 61, and the servo motor is fixedly connected to the top end of the injection pipe 5.

[0036] In this embodiment, as Figure 4 As shown, the top of the slider 66 is provided with a through hole 67. The upper and lower ends of the through hole 67 are both tapered flared structures, which can scrape off the crystalline impurities in the groove 65 when the slider 66 slides, thereby cleaning the inner wall of the groove 65.

[0037] In this embodiment, as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the cleaning component 6 also includes an injection port 68 at the bottom of the injection pipe 5.

The top of the control plate 69 has an inward concave conical structure.

[0042] The computer software involved in the hardware carriers such as servo motors and micro motors in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the utility model application.

[0043] Therefore, the "servo motor" and "micro motor" involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0044] The working process of this self-cleaning sodium hypochlorite dosing device for pipelines is as follows:

[0045] First, when the equipment is started, the servo motor drives the push rod 61 to rotate. Since the push rod 61 is threadedly connected to the support rod 62, the push rod 61 drives the support rod 62 to move upward through the threaded structure in the support rod 62. The support rod 62 drives the cleaning plate 63 at its bottom to move upward. At this time, by continuously changing the rotation direction of the push rod 61, the cleaning plate 63 is made to move up and down reciprocally. At this time, the movement of the cleaning plate 63 will continuously scrape off the crystals on the inner wall of the injection pipe 5. The scraped crystals will be carried by the flowing sodium hypochlorite solution and discharged downward from the release port 64.

[0046] Then, the sodium hypochlorite solution carries the crystals from the one-way valve at the discharge port 610 into the injection port 68 and discharges. The discharged solution enters the connecting pipe 2 and comes into contact with the water in the pipe body 1 for mixing and disinfection.

[0047] Next, when the cleaning plate 63 moves downward to the lowest point, the bottom end of the cleaning plate 63 presses down on the deflector plate 620. One side of the deflector plate 620 pushes the lever 619 that is engaged with it. The lever 619 drives the protrusion on it to rotate together. The protrusion slides in the spiral groove 618. Pressing the spiral groove 618 causes the locking lever 617 to disengage from the locking ring 616. The locking ring 616 is no longer restricted. The two spring telescopic levers 613 extend through the internal spring structure, pushing the impact lever 611 downward quickly. When the impact lever 611 moves downward, it will pull the steel rope 612, causing the steel rope 612 to be pulled out from the winding wheel 615. The impact lever 611 is inserted into the injection port 68, pushing out the crystal block in the injection port 68.

[0048] Subsequently, the cleaning plate 63 rises, no longer pressing the deflector plate 620. The micro motor drives the transmission rod 614, which in turn drives the winding wheel 615 to rotate. The winding wheel 615 pulls the impact rod 611 through the winding steel rope 612. When the impact rod 611 rises, it compresses the spring telescopic rod 613. The locking ring 616 on the spring telescopic rod 613 gradually moves to a position parallel to the locking rod 617. At this time, since the deflector plate 620 will be reset upward by the return spring, the rise of the deflector plate 620 will push the lever 619 to rotate in the opposite direction. The reverse rotation of the lever 619 will slide in the opposite direction in the spiral groove 618 through the protrusion, thereby pushing out the locking rod 617. The locking rod 617 is inserted into the locking ring 616 again, thereby restricting the unfolding movement of the spring telescopic rod 613. At this time, the position of the impact rod 611 is locked, waiting for the next trigger.
