Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and specifically discloses an automatic dosing device for circulating water. Background Technology

[0002] Water treatment methods include physical treatment and chemical treatment. Physical treatment methods include using filter media with different pore sizes to remove impurities from the water through adsorption or blocking. Common adsorption methods mostly use activated carbon for adsorption, while common blocking methods involve passing water through filter media to prevent larger impurities from passing through, thereby obtaining relatively pure water.

[0003] When a cooling tower has been in use for a long time, calcium and magnesium ions in the circulating water will form scale on the surface of the equipment and pipes, reducing heat transfer efficiency and affecting the normal operation of the system. Most existing treatment methods involve directly adding chemicals into the cooling tower. Although this method can remove scale, uneven addition of chemicals will result in poor scale removal, thus affecting the normal operation of the cooling tower in the future. Utility Model Content

[0018] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0019] Example 1 like Figure 1-4 As shown, the automatic circulating water dosing equipment includes an inlet pipe 1 and a storage tank 3 located at the top of the inlet pipe 1, and further includes: The connecting pipe 4, which is located in the middle of the inner cavity of the medicine storage tank 3, is rotatably installed. The top end of the connecting pipe 4 is connected to a drive mechanism, which is used to drive the connecting pipe 4 to rotate at multiple angles. A sealing element 10 is fixedly installed at the bottom of the inner cavity of the medicine storage tank 3. A sealing element 21 is fixedly installed at the bottom end of the sealing element 10. A connecting pipe 4 passes through and rotatably connects the sealing element 10 and the sealing element 21. The sealing element 10, the sealing element 21 and the connecting pipe 4 are all sealed. The dosing mechanism, located on the outer surface of the connecting pipe 4, is used to uniformly add the medicine into the inlet pipe 1.

[0020] This invention enables the water inlet pipe 1 to be fixedly connected to the medicine storage tank 3 by setting a connecting flange 2; by setting a sealing element 10 and a sealing element 21, it ensures that the water inlet pipe 1 and the medicine storage tank 3 are sealed while the connecting pipe 4 rotates, thereby avoiding gaps that may affect subsequent processing; by setting a driving mechanism, the connecting pipe 4 can be driven to rotate at multiple angles. When the connecting pipe 4 rotates, it can not only stir the medicine and water, but also cooperate with the dosing mechanism to spray the medicine evenly, so that the medicine can be fully mixed with the water, which facilitates the subsequent treatment of the water inlet pipe 1 and the inner wall of the cooling tower.

[0021] The top end of the water inlet pipe 1 is fixedly equipped with a connecting flange 2 to the medicine storage tank 3, and the connecting flange 2 is fixedly connected to the medicine storage tank 3 by several bolts.

[0022] The bottom of the connecting pipe 4 passes through the first seal 10 and the second seal 11 and extends into the water inlet pipe 1. A stepped groove is provided on the inner wall of the water inlet pipe 1 to match the second seal 11, and the second seal 11 can be embedded in the stepped groove.

[0023] With the above setup, the connecting flange 2 fixes the medicine storage tank 3 to the water inlet pipe 1 with several bolts; by setting the sealing element 10 and the sealing element 21, it can be ensured that the connecting pipe 4 rotates while sealing the water inlet pipe 1 and the medicine storage tank 3, thereby avoiding gaps that may affect subsequent processing.

[0024] The drive mechanism includes a worm gear 5, a worm 6, and a servo motor 7. The worm gear 5 is fixedly mounted on the top of the connecting pipe 4, the worm 6 is meshed with one side of the worm gear 5, the output end of the servo motor 7 is fixedly connected to one end of the worm 6, and the servo motor 7 is fixedly mounted on the upper surface of the medicine storage tank 3.

[0025] The top end of the connecting pipe 4 penetrates the upper end face of the medicine storage tank 3 and is fixedly connected to the worm gear component 5. The middle part of the worm gear component 5 is provided with a through hole through which the connecting pipe 4 passes, and the connecting pipe 4 is connected to the through hole.

[0026] With the above settings, the servo motor 7 can drive the worm gear 6 to rotate, and the worm gear 6 is meshed with the worm wheel 5. The rotation of the worm gear 6 can drive the worm wheel 5 to rotate accordingly, which can facilitate the subsequent drive adjustment of the connecting pipe 4.

[0027] The dosing mechanism includes a guide tube 14, a connecting pump 15, and a rotating connecting port 16. One end of the guide tube 14 is fixedly connected to the bottom of one side of the medicine storage tank 3, and the other end of the guide tube 14 is fixedly connected to the connecting pump 15. The connecting pump 15 is fixedly installed on the upper surface of the medicine storage tank 3. The rotating connecting port 16 is fixedly connected to the end of the connecting pump 15 away from the guide tube 14. The end of the rotating connecting port 16 away from the connecting pump 15 passes through a through hole and extends into the connecting tube 4.

[0028] The outer diameter of the rotary connection port 16, the diameter of the through hole, and the inner diameter of the connecting pipe 4 are adapted to each other, and the rotary connection port 16 rotatably connects the through hole and the connecting pipe 4.

[0029] With the above configuration, the connecting pipe 4 has a hollow structure, which facilitates the subsequent guidance of the medicine. By setting the connecting pump 15, the medicine in the medicine storage tank 3 can be drawn and guided through the guiding pipe 14. The end of the rotating connecting port 16 away from the connecting pump 15 extends into the connecting pipe 4, so that the medicine drawn into the connecting pump 15 can be pumped into the connecting pipe 4 through the rotating connecting port 16. Thus, the medicine can be replenished normally while the connecting pipe 4 is rotating.

[0030] The outer surface of the connecting pipe 4 is uniformly and spaced along the circumference with a number of mixing paddles 8. The outer surface of the connecting pipe 4 is also fixed with two sets of stirring rods 1 9 and one set of stirring rods 2 17 from top to bottom. The stirring rods 1 9 are in an L-shaped structure and the two sets of stirring rods 1 9 are symmetrically arranged.

[0031] The mixing paddle 8 is provided in five parts, and each set of stirring rod 1 9 and stirring rod 2 17 is provided in five parts in conjunction with the mixing paddle 8.

[0032] With the above settings, the medicine in the medicine storage tank 3 can be uniformly stirred and mixed by setting the mixing paddle 8, stirring rod 1 9 and stirring rod 2 17.

[0033] The outer surface of the bottom of the connecting pipe 4 is uniformly and spaced along the circumference with a number of dispersing blades 12. The dispersing blades 12 are all located inside the water inlet pipe 1. The outer surface of the bottom of the connecting pipe 4 is uniformly and spaced with a number of spraying ends 13 in conjunction with the dispersing blades 12. The spraying ends 13 and the dispersing blades 12 are arranged alternately.

[0034] With the above configuration, by setting up several sets of spray ends 13 and several sets of dispersing blades 12, and by staggering the sets of spray ends 13 and several sets of dispersing blades 12, the agent can be sprayed evenly, so that the agent and water can be fully mixed.

[0035] Working principle and process: When stirring is required, the servo motor 7 is first started to drive the worm gear 6 to rotate. The rotation of the worm gear 6 drives the worm wheel 5 to rotate, which in turn drives the connecting pipe 4 to rotate. The rotation of the connecting pipe 4 drives the mixing paddle 8, stirring rod 1 9 and stirring rod 2 17 to rotate, so as to fully mix the medicine and water. At this time, the connecting pump 15 is started to draw and guide the medicine in the storage tank 3 through the guide pipe 14. The medicine drawn into the connecting pump 15 is pumped into the connecting pipe 4 through the rotating connecting port 16, so that the medicine can be replenished normally while the connecting pipe 4 is rotating. The medicine flows into the water inlet pipe 1 along the connecting pipe 4 and is evenly sprayed into the water inlet pipe 1 through several sets of spray ends 13, where it is fully mixed with water, which facilitates the subsequent treatment of the water inlet pipe 1 and the inner wall of the cooling tower.
