Description

Technical Field

[0001] The present invention relates to the field of PAM dosing, in particular to an intelligent PAM automatic dosing device. Background Art

[0002] PAM (polyacrylamide) is widely used in water treatment and is mainly used as a flocculant in the following aspects:

[0003] Raw water purification principle: Raw water usually contains various suspended particles, colloidal substances and other impurities. As a flocculant, PAM makes the particles aggregate into larger flocs through the interaction between the active groups on its polymer chain and the charges on the surface of the suspended particles. At the same time, the long-chain structure of PAM can bridge multiple particles together, accelerating the sedimentation of the particles, so as to achieve the purpose of purifying water quality;

[0004] Sewage treatment principle: In sewage treatment, PAM also uses its flocculation effect to make the suspended solids, colloidal substances and some flocculable organic substances in the sewage form large flocs, which are convenient to be separated from the sewage by methods such as precipitation or flotation. For some sewage containing fine particles or pollutants that are difficult to precipitate, the addition of PAM can significantly improve the precipitation performance and improve the sewage treatment efficiency;

[0005] Sludge treatment principle: Sludge is the solid waste generated in the sewage treatment process, containing a large amount of water and organic matter. PAM changes the structure and properties of the sludge through flocculation with the particulate matter in the sludge, reduces the hydrophilicity of the sludge, and makes the water in the sludge easier to be separated under the action of mechanical pressure or natural gravity;

[0006] Advanced water treatment principle: In some advanced water treatment processes with high water quality requirements, such as reverse osmosis pretreatment, ultrafiltration, etc., PAM can be used as a pretreatment agent to remove the tiny particles and colloidal substances in the water, prevent them from causing blockage and pollution in the subsequent treatment equipment, and improve the service life and treatment effect of the membrane.

[0007] However, no matter which of the above uses, when specifically used and dosed, it is necessary to control the dosage of PAM to avoid failing to meet the corresponding treatment standards or causing secondary pollution to the water body. At present, the use of PAM is to first prepare it into a solution reagent by manual weighing and then dose it. However, manual weighing and preparation not only have low efficiency, but also easily cause large errors in the concentration accuracy of the prepared solution. Therefore, an intelligent PAM automatic dosing device is proposed. Summary of the Invention

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached Figure 1 to the attached Figure 8 Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] As Figures 1-6As shown in the figure, the present invention discloses an intelligent PAM automatic dosing device, which includes a reagent preparation tank 1 and a mounting frame 2. A storage tank 3 is installed inside the mounting frame 2. A discharge port 36 is opened below the storage tank 3. Slide seats 7 are symmetrically slid on both sides of the mounting frame 2. A rotating shaft 8 is rotatably connected to the side of each of the two slide seats 7 close to each other. An installation frame 9 is connected between the rotating shafts 8 on both sides. A weighing scale is installed on the installation frame 9, and a receiving cylinder 11 is installed through the weighing scale. A gear 12 is sleeved on the rotating shaft 8. A first guide rod 16 is connected to the slide seat 7, and a first rack 15 meshing with the gear 12 is slidably sleeved on the first guide rod 16. The weighing scale is an existing electronic scale in grams and accurate to two decimal places;

[0037] A baffle 19 that abuts against the lower end of the first rack 15 is connected to the mounting frame 2. Sealing covers 22 that hermetically sleeve the discharge port 36 are symmetrically and slidably connected to the mounting frame 2. A linkage component is provided on the slide seat 7. The linkage component is used to drive the two sealing covers 22 to approach each other when the slide seat 7 moves upward. A driving component is provided inside the mounting frame 2. The driving component is used to drive the slide seat 7 to slide up and down inside the mounting frame 2.

[0038] During operation, PAM with the required weight is added into the receiving cylinder 11 through the discharge port 36. Then, the driving component is controlled to drive the slide seat 7 to move downward. The lower end of the first rack 15 will abut against the baffle 19. While the slide seat 7 and the installation frame 9 are still moving downward, at this time, the first rack 15 moves upward relative to the installation frame 9, which can drive the gear 12 to rotate. While driving the installation frame 9 and the receiving cylinder 11 thereon to move downward through the rotating shaft 8, it will also turn over, so as to drop the PAM received from the discharge port 36 into the lower reagent preparation tank 1 and mix it with the water in the reagent preparation tank 1 to dissolve, realizing automatic and efficient weighing and dosing, and greatly improving the preparation efficiency of the PAM reagent.

[0039] Electric heating wires 26 are installed on the inner walls of the two sealing covers 22. A feeding pipe 4 is opened at the upper end of the storage tank 3. A frame body 27 is connected to the installation frame 9. A limiting frame 28 for limiting the frame body 27 is connected to the slide seat 7. An electric spiral surface 35 is installed inside the storage tank 3 and extends to the outside of the discharge port 36, so that before the two sealing covers 22 approach each other to hermetically sleeve the discharge port 36, the periphery of the discharge port 36 can be heated to discharge the humid air. At the same time, the setting of the electric spiral surface 35 can facilitate and orderly discharge the PAM in the storage tank 3.

[0040] A sleeve 13 is connected to the installation frame 9. A slide rod 14 is slidably sleeved inside the sleeve 13. The first rack 15 is slidably sleeved outside the slide rod 14. The settings of the sleeve 13 and the slide rod 14 can stabilize the sliding of the first rack 15.

[0041] One side of the first rack 15 is connected with a collar 17. The collar 17 is slidably sleeved on the outside of the first guide rod 16. A first spring 18 sleeved on the outside of the first guide rod 16 is connected between the collar 17 and the first guide rod 16. So that under the action of no external force, the first rack 15 can move downward under the action of its own gravity and the elastic force of the first spring 18 until the collar 17 is limited by the sliding seat 7.

[0042] The inner walls on both sides of the mounting frame 2 are connected with connecting frames 20, and a second guide rod 21 is connected between the connecting frames 20 on both sides. The two sealing covers 22 are respectively slidably sleeved at both ends of the second guide rod 21. A limiting ring is centrally connected on the second guide rod 21. A second spring 23 sleeved on the outside of the second guide rod 21 is connected between the mutually close sides of the two sealing covers 22 and the limiting ring. So that under the action of no external force, the two sealing covers 22 can stably slide away from each other under the action of the elastic force of the second spring 23 to cancel the sealing of the discharge port 36 for convenient feeding.

[0043] Embodiment Two:

[0044] As Figures 1-6 shown, the present invention discloses an intelligent PAM automatic dosing device. Compared with Embodiment One, the structure of the linkage assembly is disclosed in this embodiment.

[0045] The linkage assembly includes an inclined block 24 and an L-shaped top plate 25. The inclined block 24 is connected to the mutually far sides of the two sealing covers 22. The L-shaped top plate 25 is connected to both of the sliding seats 7. The L-shaped top plate 25 is in sliding contact connection with the inclined surface of the inclined block 24 on its respective side. Thus, when the driving assembly drives the sliding seat 7 to move upward, the L-shaped top plate 25 will contact the inclined surface of the inclined block 24, and drive the two inclined blocks 24 and the sealing covers 22 to compress the second spring 23 and approach each other to seal the discharge port 36.

[0046] Embodiment Three:

[0047] As Figures 1-6 shown, the present invention discloses an intelligent PAM automatic dosing device. Compared with Embodiment Two, the structure of the driving assembly is disclosed in this embodiment.

[0048] The driving assembly includes guide rails 5 and guide blocks 6. The guide rails 5 are installed on the inner walls on both sides of the mounting frame 2. The guide blocks 6 are slidably connected in their respective guide rails 5. The sliding seats 7 are respectively connected to the guide blocks 6 on their respective sides to facilitate the up and down sliding control of the sliding seats 7.

[0049] Embodiment Four:

[0050] As Figures 1-8 shown, the present invention discloses an intelligent PAM automatic dosing device. Compared with Embodiment Three, the structure for vibrating and feeding the receiving cylinder 11 is disclosed in this embodiment.

[0051] Each sliding seat 7 is further connected with a toothed plate 29. The inner walls on both sides of the mounting frame 2 are connected with limit sliding boxes 30. A limit block 31 is slidably connected in the limit sliding box 30. One end of the limit block 31 passes through the limit sliding box 30 and extends to the outside thereof, and a second rack 32 that fits with the toothed plate 29 is connected to the extended end. A third spring 33 is connected between the limit block 31 and the inner wall of the limit sliding box 30. In this way, when the sliding seat 7 moves up and down, the sliding seat 7 moves up and down. Especially when moving downward, the mounting frame 9 and the material receiving cylinder 11 thereon can vibrate through the fitting of the toothed plate 29 and the second rack 32, and the PAM contained in the material receiving cylinder 11 can be added to the lower chemical preparation tank 1 as comprehensively as possible.

[0052] Embodiment 5:

[0053] As Figures 1-8 shown, the present invention discloses an intelligent PAM automatic dosing device. Compared with Embodiment 4, this embodiment discloses a structure for cleaning the inner wall of the material receiving cylinder 11 and accurately dosing PAM.

[0054] A motor 10 is installed on the mounting frame 9, and a weighing scale is installed at the output end of the motor 10. The material receiving cylinder 11 is installed on the weighing scale. Scrapers 34 are further connected to the sliding seats 7 on both sides. Both scrapers 34 extend into the material receiving cylinder 11 and are symmetrically arranged along the radial direction of the material receiving cylinder 11. The scrapers 34 are slidably attached to the inner wall of the material receiving cylinder 11. An electric stirring rod is also installed in the chemical preparation tank 1. After the material receiving cylinder 11 is turned downward for feeding, some PAM may still adhere to its inner wall, resulting in an error in the actual addition amount. At this time, starting the motor 10 to drive the material receiving cylinder 11 to rotate can scrape all the PAM on the inner wall of the material receiving cylinder 11 by the scrapers 34 and add it to the lower chemical preparation tank 1, realizing the accurate dosing and preparation of the PAM reagent.

[0055] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments.
