Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a scale inhibitor dosing device for RO water treatment. Background Technology

[0002] With the increasing demand for water from industrial production and residential use, reverse osmosis (RO) water treatment technology has been widely used in municipal water supply, industrial circulating water, and wastewater treatment and reuse due to its advantages in efficiently removing impurities and purifying water. During the RO water treatment process, calcium and magnesium ions in the wastewater, which are prone to scaling, will form insoluble salt deposits (i.e., scale) on the surface of the reverse osmosis membrane. If not treated in time, this will not only lead to a decrease in membrane flux and filtration efficiency, but also shorten the lifespan of the reverse osmosis membrane, increasing equipment maintenance costs and replacement frequency. Therefore, effectively descaling the wastewater in the RO water treatment system is a key step in ensuring the stable operation of the equipment.

[0003] However, in existing RO water treatment processes, scale inhibitors are mainly added manually or by machine. However, these two methods cannot ensure that the wastewater and scale inhibitors are fully mixed and reacted, thus affecting the wastewater treatment effect. Utility Model Content

[0004] The purpose of this invention is to provide a scale inhibitor dosing device for RO water treatment, which can drive the first and second paddles to rotate in opposite directions, thereby fully mixing the wastewater with the scale inhibitor and improving the scale removal effect of the wastewater. While stirring the wastewater, the scale inhibitor inside the storage tank can be intermittently dropped into the wastewater, thereby further improving the scale removal effect of the wastewater.

[0008] According to the aforementioned scale inhibitor dosing device for RO water treatment, the outer surface of the rotating shaft is rotatably connected to the cavity box, and the outer surface of the sleeve rod is rotatably connected to the protective box.

[0009] According to the aforementioned scale inhibitor dosing device for RO water treatment, the first conical tooth meshes with the second conical tooth, and the second conical tooth meshes with the third conical tooth.

[0019] Reference Figure 1-5This utility model discloses a scale inhibitor dosing device for RO water treatment, comprising: a cavity box 1; a motor 2 fixedly connected to the upper surface of the cavity box 1; a rotating shaft 3 fixedly connected to the output end of the motor 2; a first impeller 4 fixedly connected to the outer surface of the rotating shaft 3; a protective box 5 fixedly connected to the lower surface of the cavity box 1; a first conical tooth 6 fixedly connected to the outer surface of the rotating shaft 3; a connecting shaft 7 rotatably connected inside the protective box 5; a limit block 8 fixedly connected to the left end of the connecting shaft 7; a second conical tooth 9 fixedly connected to the outer surface of the connecting shaft 7; a sleeve rod 10 rotatably connected inside the protective box 5; and a second impeller 11 fixedly connected to the outer surface of the sleeve rod 10. The outer surface of the sleeve rod 10 is fixedly connected with a third conical tooth 12. The outer surface of the cavity box 1 is provided with four mounting holes 24 arranged in a rectangular array to facilitate the installation of the device on the sewage container. The outer surface of the rotating shaft 3 is rotatably connected to the cavity box 1, and the outer surface of the sleeve rod 10 is rotatably connected to the protective box 5. The first conical tooth 6 meshes with the second conical tooth 9, and the second conical tooth 9 meshes with the third conical tooth 12 to facilitate the rotation of the first and second blades in opposite directions. The sleeve rod 10 is sleeved on the outer surface of the rotating shaft 3. There are two second blades 11 arranged vertically. The motor 2 is electrically connected to an external power source.

[0020] A half gear 13 is fixedly connected to the outer surface of the rotating shaft 3. A guide rod 14 is fixedly connected to the inside of the cavity box 1. A limit block 15 is fixedly connected to the front end of the guide rod 14. A spring 16 is provided on the outer surface of the guide rod 14. A baffle 17 is slidably connected to the outer surface of the guide rod 14. A toothed plate 18 is fixedly connected to the left surface of the baffle 17. An opening groove 19 is provided on the outer surface of the baffle 17. A storage box 20 is fixedly connected to the inner surface of the opening groove 19. A feeding pipe 21 is provided on the upper surface of the storage box 20. A pipe cap 22 is threadedly connected to the outer surface of the feeding pipe 21. A discharge hole 23 is provided on the lower surface of the cavity box 1. The half gear 13 meshes with the toothed plate 18. The opening groove 19 is adapted to the discharge hole 23, which facilitates the addition of scale inhibitor to the sewage.

[0021] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0022] Working principle: In use, the cavity box 1 is installed and fixed on the sewage container using the mounting hole 24. When the sewage needs to be descaled, the motor 2 is started, driving the rotating shaft 3 to rotate the first impeller 4 and the second impeller 11 in opposite directions under the meshing action of the first conical tooth 6 and the second conical tooth 9, and the second conical tooth 9 and the third conical tooth 12. This allows the sewage and the scale inhibitor added to the sewage to be fully stirred, thereby improving the descaling effect of the sewage. At the same time as the rotating shaft 3 rotates, under the meshing action of the half gear 13 and the toothed plate 18, the baffle 17 will move backward along the guide rod 14. When the spring 16 is compressed, and the opening groove 19 on the baffle 17 overlaps with the discharge hole 23, the scale inhibitor inside the storage tank 20 will fall into the sewage through the opening groove 19 and the discharge hole 23. When the half gear 13 continues to rotate, and the toothed part on the half gear 13 disengages from the toothed plate 18, the baffle 17 will automatically reset under the action of the spring 16, so that the opening groove 19 and the discharge hole 23 are misaligned, thus preventing the scale inhibitor inside the storage tank 20 from falling. In this way, the scale inhibitor inside the storage tank 20 will intermittently fall into the stirred sewage, thereby further improving the descaling effect of the sewage.
