Description

Technical Field

[0001] The utility model relates to the technical field of acid addition in circulating water, in particular to a device for automatically adding concentrated sulfuric acid to circulating water. Background Art

[0002] The main purpose of adding acid to the circulating cooling water system is to lower the pH value and stabilize the bicarbonate. Sulfuric acid is added to the circulating cooling water system to convert the carbonate calcium hardness in the water into non-carbonate calcium hardness with high solubility, so that the carbonate calcium hardness in the water is reduced to below the scaling danger limit, thereby preventing the formation of calcium carbonate scale. However, the existing automatic addition device for concentrated sulfuric acid in circulating water directly injects concentrated sulfuric acid into the circulating water. At this time, the concentrated sulfuric acid in the circulating water is unevenly mixed, resulting in part of the circulating water not being fully reacted, thereby forming calcium carbonate scale.

[0003] Therefore, we propose an automatic adding device of concentrated sulfuric acid to circulating water. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is in use, the impeller is driven to rotate when the circulating water enters the mixing tank from the initial tank, and the rotating disk and the active bevel gear are respectively driven to rotate through the two ends of the connecting shaft. At this time, the rotating disk cooperates with the shifting column to drive the L-shaped pull rod to perform reciprocating motion, so that the concentrated sulfuric acid intermittently flows into the mixing tank, and it is avoided that too much concentrated sulfuric acid is injected at one time, which makes the reaction incomplete. The active bevel gear drives the transmission bevel gear and the driven hollow bevel gear, so that the connecting rod and the shifting rod on the connecting shaft rotate in opposite directions, so that the concentrated sulfuric acid is better mixed and reacted with the circulating water. This design avoids uneven mixing of concentrated sulfuric acid in the circulating water, thereby reducing the generation of calcium carbonate scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Working principle:

[0024] When the utility model is in use, concentrated sulfuric acid is first injected into the acid storage box 5 through the feed pipe 9. At this time, the valve between the acid storage box 5 and the conduit 81 is in a closed state; at this time, the circulating water flows from the initial pool 2 from high to low, and flows into the mixing pool 3 through the through groove 71. The impeller 72 is rotated by the flow of the circulating water, and the impeller 72 drives the connecting shaft 74 to rotate. The rotating disk 86 at the top of the connecting shaft 74 rotates and drives the lever 87 to rotate. The lever 87 slides in the slide groove 85. At this time, the L-shaped pull rod 84 forms a reciprocating motion under the restriction of the piston 83. At this time, The valve between the acid storage tank 5 and the conduit 81 is opened, so that the concentrated sulfuric acid flows into the mixing tank 3 through the discharge hole on the annular discharge ring 6. Due to the reciprocating motion of the piston 83, the concentrated sulfuric acid also flows into the mixing tank intermittently. At this time, the bottom end of the connecting shaft 74 drives the active bevel gear 75 to rotate, and drives the driven hollow bevel gear 78 to rotate through the transmission bevel gear 76, so that the active bevel gear 75 and the driven hollow bevel gear 78 rotate in opposite directions, and the hollow connecting rod 77 and the lever 79 of the connecting shaft 74 also rotate in opposite directions, so that the concentrated sulfuric acid can be better mixed with the circulating water.
