Description

Technical Field

[0001] The utility model relates to the technical field of corrosion and scale inhibitor dosing devices, and more specifically, to a corrosion and scale inhibitor dosing device. Background Art

[0002] In the existing technology, there are some problems with the corrosion and scale inhibitor dosing device, which affect the use effect of the agent and the convenience of operation.

[0003] First, the existing corrosion and scale inhibitor dosing device cannot separate the corrosion and scale inhibitor during mixing and the (mixed) corrosion and scale inhibitor during use when mixing the corrosion and scale inhibitor, or when using the mixed corrosion and scale inhibitor. This will lead to uneven distribution of the agent, affecting its corrosion and scale inhibition effect, which not only reduces the efficiency of the agent's use, but may also lead to a decline in the performance of the circulating water system, increase maintenance costs and operation risks.

[0004] Secondly, in the existing technology, the addition of corrosion and scale inhibitors usually requires the use of metering pumps and pipelines for transportation. However, the connection and disassembly operations of the metering pumps and pipelines in the existing technology are often cumbersome. Such cumbersome operations not only increase labor costs, but may also damage the equipment due to improper operation, affecting the normal operation of the system.

[0005] In addition, although some devices use some mechanisms to achieve quick connection and disassembly of pipes, these mechanisms are often simple in structure and cannot guarantee the sealing of the connections. This sealing problem may cause leakage of the reagents, which not only wastes the reagents but also may pollute the environment. At the same time, the leakage problem may also lead to a decline in equipment performance and even cause safety accidents. Utility Model Content

Due to the inclined structural design of the slope 30, when one end of the clamping frame 26 is fully inserted into the clamping groove 27, the clamping frame 26 will drive the delivery pipe 7 to press the gasket through the slope 30, thereby ensuring the sealing of the connection.

At this time, the return spring 14 drives one end of the limiting rod 15 to engage into the original limiting groove 16, and then the two limiting sleeves 12 are rotated in the opposite direction to reset the two limiting sleeves 12. Then the inner wall of the limiting sleeve 12 limits the outer side of the limiting rod 15 again to prevent the limiting rod 15 from moving. Then the limiting rod 15 and the limiting groove 16 cooperate to limit the matching sleeve 13 and the matching frame 8, thereby preventing the matching frame 8 and the guide block 11 from moving.

Due to the rounded structure design at the end of the limiting rod 15 and the edge of the limiting groove 16, and the reset spring 14 only provides a weak reset force, then the side wall of the limiting groove 16 will press on the end of the limiting rod 15. The upper and lower ends of the limiting rod 15 are squeezed, so that one end of the limiting rod 15 slides out of the limiting groove 16, and the other end of the limiting rod 15 drives the return spring 14 to stretch. At the same time, the matching frame 8 drives the guide block 11 to move. Due to the special structural design of the guide block 11, when the guide block 11 moves, it will push the guide rod 10 open, and then the guide rod 10 will drive the clamping frame 26 to move outward. At the same time, the clamping frame 26 will drive the tension spring 28 set inside to stretch, and then insert one end of the delivery pipe 7 into the fixed pipe 9 and make one end of the delivery pipe 7 against the sealing sleeve 29. Then the matching frame 8 is rotated in the opposite direction, and the matching frame 8 drives the guide block 11 to reset, and then the guide rod 10 loses the limit of the guide block 11, and then the tension spring 28 drives the clamping frame 26 and the guide rod 10 to reset, and then one end of the clamping frame 26 is inserted into the clamping groove 27. Due to the inclined structural design of the slope 30, when one end of the clamping frame 26 is fully inserted into the clamping groove 27, the clamping frame 26 drives the delivery pipe 7 to press the gasket through the slope 30, thereby ensuring the sealing of the connection. At the same time, multiple sealing rings are arranged on the outside of the delivery pipe 7 31 will be engaged in the corresponding sealing groove 32, thereby further enhancing the sealing performance of the pipeline connection. At this time, the return spring 14 drives one end of the limiting rod 15 to be engaged in the original limiting groove 16, and then the two limiting sleeves 12 are rotated in the opposite direction to reset the two limiting sleeves 12. Then the inner wall of the limiting sleeve 12 limits the outer side of the limiting rod 15 again to prevent the limiting rod 15 from moving. Then the limiting rod 15 and the limiting groove 16 cooperate to limit the matching sleeve 13 and the matching frame 8, thereby preventing the matching frame 8 and the guide block 11 from moving.

[0042] When the device needs to be used, first open the cover plate 40, then put the medicine into the mixing tank 1 from the feeding port opened on the tank cover 17, then reinstall the cover plate 40 at the corresponding position on the tank cover 17, and then turn on the motor 19. The motor 19 drives the mixing frame 20 to rotate, so that the mixing frame 20 mixes the medicine in the mixing tank 1. When the mixing is completed, open the cylinder 23, and the cylinder 23 drives the piston rod 24 to move. Then the piston rod 24 drives the movable rod 5 to rotate with the corresponding connecting seat 6 set on the outside of the mixing tank 1 as the center through the connecting seat 6 and the connecting frame 25. At the same time, the cylinder 23 will move through the connecting frame 25 connected on the other side and the other connecting seat 6 set on the outside of the tank cover 17, and then the movable rod 5 will drive the blocking plate 4 to move, so that the blocking plate 4 no longer blocks the mixing tank 1. Due to gravity, the mixed medicine liquid in the mixing tank 1 will pass through the filtration of the filter plate 21 and enter the isolation chamber 2 set below, and then drive the cylinder 23 to move in the opposite direction, and then make the piston rod 24 drive the movable rod 5 and the sealing plate 4 to reset, so that the sealing plate 4 re-seals the mixing tank 1, and then put the medicine into the mixing tank 1 again for mixing.
