Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of polyaluminum chloride dosing devices, specifically a polyaluminum chloride dosing device. Background Technology
[0002] A polyaluminum chloride (PAC) dosing device is a specialized device for quantitatively adding PAC to water. It can precisely control the dosage according to actual needs, ensuring thorough mixing of the agent with the water. This effectively leverages the coagulation and sedimentation properties of PAC in water treatment, thereby improving water quality. It is commonly used in various water treatment scenarios.
[0003] Existing polyaluminum chloride dosing devices often utilize the gravity of the agent. Through a high-level storage tank, the agent flows into the water to be treated via a pipeline under its own weight. This method has a simple structure, and the dosage is mainly controlled by adjusting the opening of the outlet valve of the storage tank.
[0004] However, in actual use, the flow characteristics of most valves are nonlinear, such as commonly used ball valves and gate valves. When the valve is open at a small degree, the flow rate changes relatively slowly; while when it is close to fully open, the flow rate is extremely sensitive to the change in opening. This means that when controlling the dosage of polyaluminum chloride by the valve opening, it is difficult to achieve precise linear control. It is difficult for operators to accurately grasp the relationship between the opening and the dosage. Therefore, we propose a polyaluminum chloride dispenser. Utility Model Content
[0005] The purpose of this invention is to provide a polyaluminum chloride dosing device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyaluminum chloride dosing device, comprising a dosing device tank, a feeding pipe connected to the surface of the dosing device tank, an inlet pipe connected to the arc surface of the dosing device tank, a tank cover installed at the tank opening of the dosing device tank, an adjustment structure provided on the surface of the feeding pipe, the adjustment structure comprising a rotating rod inserted into the arc surface of the feeding pipe, a baffle rotating on the inner wall of the feeding pipe, the baffle being fixedly connected to one end of the rotating rod, a ring fixedly connected to the arc surface of the feeding pipe, an extension plate fixedly connected to the arc surface of the rotating rod, a pin slidingly passing through the surface of the extension plate, and a plurality of limiting holes provided on the arc surface of the ring, the size of the pin being adapted to the size of the limiting holes.
[0007] The effect achieved by the above components is as follows: by setting an adjustment structure, the rotating rod drives the baffle to rotate, which can flexibly change the flow area of the feed pipe, so that the operator can accurately grasp the relationship between the opening degree and the dosage, and thus accurately control the addition of polyaluminum chloride.
[0008] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the extension plate, respectively.
[0009] The effect achieved by the above components is that the pin, under the action of the spring force, improves the stability of the insertion into the limiting hole, thereby preventing the pin from coming out of the limiting hole.
[0010] Preferably, a turntable is fixedly connected to the end of the rotating rod away from the feeding pipe, and the vertical cross section of the turntable is in the shape of a cross.
[0011] The effect achieved by the above components is that the turntable at one end of the rotating rod is designed in a "+" shape, which increases the friction during operation and makes it easier for the operator to rotate the rotating rod.
[0012] Preferably, the surface of the ring is fixedly connected with several scale marks, and the arc surface of the rotating rod is fixedly connected with a pointer.
[0013] The effect achieved by the above components is that the scale marks on the surface of the ring and the pointer on the rotating rod work together to form a visual adjustment indicator structure. Operators can intuitively understand the rotation angle of the rotating rod, thereby judging the opening of the baffle, accurately grasping the change of the dosage, reducing the difficulty of operation, and improving the adjustment efficiency.

Several stirring rods are fixedly connected to the arc surface of the rotating shaft. Several rectangular rods are fixedly connected to the arc surface of the rotating shaft. A scraper is fixedly connected to the end of the rectangular rod away from the rotating shaft.
[0015] The effect achieved by the above components is as follows: by setting up a stirring structure, the servo motor drives the rotating shaft to rotate, and the stirring rod fixed on the rotating shaft rotates accordingly to stir the polyaluminum chloride agent. At the same time, the rotating shaft drives the rectangular rod to rotate, and the scraper at the end of the rectangular rod also rotates. The scraper makes it easy to scrape off the polyaluminum chloride adhering to the inner wall of the dosing tank, thereby avoiding the situation where polyaluminum chloride adheres to its inner wall and is inconvenient to clean.
[0016] Preferably, the surface of the scraper has several round holes.
[0017] The effect achieved by the above components is that the round hole design on the surface of the scraper allows the medicine to pass through better when the scraper rotates, further enhancing the stirring effect.
[0018] Preferably, a protective strip is fixedly connected to the side of the scraper near the inner wall of the feeder tank, and the protective strip is made of rubber.
[0019] The effect achieved by the above components is as follows: the rubber protective strip on the side of the scraper near the inner wall of the tank can protect the inner wall of the tank and make the scraper fit more closely to the inner wall of the tank, scraping off the agent adhering to the tank wall, ensuring the uniform mixing of the agent in the tank, and enabling the added agent to play a more effective role in coagulation and sedimentation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-5 This utility model provides a technical solution: a polyaluminum chloride dosing device, including a dosing tank 1, a feeding pipe 2 connected to the surface of the dosing tank, a feeding pipe 3 connected to the arc surface of the dosing tank, a tank cover 4 installed at the opening of the dosing tank, and an adjustment structure 5 provided on the surface of the feeding pipe 2. By setting the adjustment structure 5, the rotating rod 501 drives the baffle 502 to rotate, which can flexibly change the flow area of the feeding pipe 2, so that the operator can accurately grasp the relationship between the opening degree and the dosing amount, and thus accurately control the dosing of polyaluminum chloride. The surface of the can lid 4 is provided with a stirring structure 6. By setting the stirring structure 6, the servo motor 61 drives the rotating shaft 62 to rotate, and the stirring rod 63 fixed on the rotating shaft 62 rotates accordingly to stir the polyaluminum chloride agent. At the same time, the rotating shaft 62 drives the rectangular rod 64 to rotate, and the scraper 65 at the end of the rectangular rod 64 also rotates. The scraper 65 facilitates the scraping of polyaluminum chloride adhering to the inner wall of the dosing tank 1, thereby avoiding the situation where polyaluminum chloride adheres to its inner wall and is inconvenient to clean.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting structure 5 includes a rotating rod 501, which is inserted into the arc surface of the feeding tube 2. A baffle 502 is rotatably mounted on the inner wall of the feeding tube 2. The baffle 502 is fixedly connected to one end of the rotating rod 501. A ring 503 is fixedly connected to the arc surface of the feeding tube 2. An extension plate 504 is fixedly connected to the arc surface of the rotating rod 501. A pin 505 slides through the surface of the extension plate 504. Several limiting holes 506 are provided on the arc surface of the ring 503. The size of the pin 505 is adapted to the size of the limiting holes 506. A spring 507 is sleeved on the arc surface of the pin 505. The two ends of the spring 507 are fixedly connected to the pin 505 and the extension plate 504, respectively. Under the elastic force of the spring 507, the stability of the pin 505 inserted into the limiting holes 506 is improved, thereby preventing the pin 505 from coming out of the limiting holes 506. A turntable 508 is fixedly connected to the end of the rotating rod 501 away from the feeding pipe 2. The vertical cross-section of the turntable 508 is in the shape of a cross. The design of the turntable 508 at one end of the rotating rod 501 in the shape of a cross increases the friction during operation, making it easier for the operator to rotate the rotating rod 501. Several scale marks 509 are fixedly connected to the surface of the ring 503, and a pointer 510 is fixedly connected to the arc surface of the rotating rod 501. The scale marks 509 on the surface of the ring 503 and the pointer 510 on the rotating rod 501 cooperate to form a visual adjustment indicator structure. The operator can intuitively understand the rotation angle of the rotating rod 501, thereby judging the opening degree of the baffle 502, accurately grasping the change of the feeding amount, reducing the difficulty of operation, and improving the adjustment efficiency.
[0032] Reference Figure 4 and Figure 5 As shown, specifically, the stirring structure 6 includes a servo motor 61. The output end of the servo motor 61 is fixedly connected to a rotating shaft 62. Several stirring rods 63 are fixedly connected to the arc surface of the rotating shaft 62, and several rectangular rods 64 are fixedly connected to the arc surface of the rotating shaft 62. A scraper 65 is fixedly connected to the end of each rectangular rod 64 away from the rotating shaft 62. Several circular holes 66 are formed on the surface of the scraper 65. The design of the circular holes 66 on the surface of the scraper 65 allows the agent to pass through better when the scraper 65 rotates, further enhancing the stirring effect. A protective strip 67 is fixedly connected to the side of the scraper 65 near the inner wall of the dosing tank 1. The protective strip 67 is made of rubber. The rubber protective strip 67 on the side of the scraper 65 near the inner wall of the tank can both protect the inner wall of the tank and allow the scraper 65 to fit more tightly against the inner wall of the tank, scraping off the agent adhering to the tank wall, ensuring uniform mixing of the agent in the tank, and enabling the added agent to more effectively exert its coagulation and sedimentation effect.
[0033] Working principle: When polyaluminum chloride needs to be added to the water to be treated, the operating adjustment structure 5 is activated. By rotating the turntable 508, the rotating rod 501 rotates, and the baffle 502, which is fixedly connected to one end of the rotating rod 501, rotates accordingly, changing the flow area of the feed pipe 2, thereby controlling the dosage of the agent. After adjusting to the appropriate dosage, the pin 505 is inserted into the corresponding limiting hole 506. Under the elastic force of the spring 507, the pin 505 is more stable in the limiting hole 506, thus preventing the pin 505 from coming out of the limiting hole 506. The scale 509 on the surface of the ring 503 and the pointer 510 on the rotating rod 501 help the operator to accurately control the opening of the baffle 502, improving the accuracy of the dosage adjustment. Under the action of gravity, the polyaluminum chloride flows into the water to be treated through the feed pipe 2, achieving the purpose of quantitative addition.
[0034] When the polyaluminum chloride (PAC) dispenser is in operation, PAC is first added into the dispenser tank 1 through the feed pipe 3. After the addition is completed, the feed pipe 3 is closed. At this time, the stirring structure 6 takes effect, and the servo motor 61 is turned on. Its output end drives the rotating shaft 62 to rotate, and the stirring rod 63 fixed on the rotating shaft 62 rotates accordingly to stir the PAC in the tank, making it more evenly distributed and avoiding sedimentation or clumping. At the same time, the rotating shaft 62 drives the rectangular rod 64 to rotate, and the scraper 65 at the end of the rectangular rod 64 also rotates. The scraper 65 makes it easier to scrape off the PAC adhering to the inner wall of the dispenser tank 1, thus avoiding the situation where PAC adheres to the inner wall and is inconvenient to clean. The round holes 66 on the surface of the scraper 65 allow the agent to pass through better, and the rubber protective strip 67 on the side of the scraper 65 near the inner wall of the tank can protect the inner wall of the tank when the scraper 65 rotates to prevent scratches.
