Description

Technical Field

[0001] The utility model relates to the technical field of water treatment dosing, in particular to a stirring mechanism and a treated water dosing control device. Background Art

[0002] After the cooling circulating water of a thermal power plant has been used for a long time, a large amount of hardness components such as calcium and magnesium ions in the water combine with anions such as carbonates and sulfates to form water-insoluble solid precipitates, which is scale. These scales will be deposited on the inner walls of boilers, heat exchangers, cooling towers, pipelines and other equipment, reducing heat transfer efficiency and increasing energy waste. In severe cases, they may even clog pipelines and affect the normal operation of equipment. Scale inhibitors can prevent the formation and growth of crystal nuclei of these precipitates, thereby effectively inhibiting the formation of scale.

[0003] When adding scale inhibitors to water, stirring is usually required to evenly disperse the scale inhibitors in the water. However, scale inhibitors have a high surface active component and react with water to produce gas during stirring, thereby forming foam in the vortex. These foams will adhere to the surface of pipes and equipment, forming an insulating layer, reducing heat transfer efficiency, resulting in increased energy consumption during equipment operation, and reducing overall operating efficiency.

[0004] In addition, the existing dosing device cannot effectively control the amount of dosing when adding drugs, resulting in either too much drug added to the water, causing waste and increasing costs, or too little drug added, reducing the effect of the descaling agent. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figures 1 to 6 , which is the first embodiment of the utility model. This embodiment provides a stirring mechanism. By setting a defoaming piece 102c, the advantage of such a setting is that the defoaming piece 102c cuts the foam, preventing the foam from adhering to the surface of the pipe and the equipment to form an insulation layer, thereby improving the conduction efficiency.

[0037] Specifically, the stirring assembly 100 includes an accommodation box 104, a motor 103 arranged in the accommodation box 104, an agitator 102 arranged at the output end of the motor 103, and a water storage tank 101 arranged outside the agitator 102; the agitator 102 includes a plurality of blades 102a, a rotating rod 102b arranged at the top of the blades 102a, and a defoaming member 102c arranged on the rotating rod 102b.

[0038] Under normal conditions, the bottom of the defoaming member 102c is in conflict with the top of the blade 102a. A sliding hole 102b-1 is provided on the rotating rod 102b. The height of the inner wall of the top of the sliding hole 102b-1 is higher than the top height of the water storage tank 101. The inner diameter of the water storage tank 101 is larger than the diameter of the blade 102a. A plurality of blades 102a are evenly arranged in a circle around the axis of the rotating rod 102b.

[0039] Among them, the blade 102a is bent in the direction of rotation, which is beneficial for the side wall of the blade 102a to contact the water with a larger area, and the defoaming component 102c can float on the water surface. The height of the top inner wall of the sliding hole 102b-1 is higher than the top height of the water storage tank 101. Even if the water storage tank 101 is filled with water, the defoaming component 102c can eliminate the foam floating on the surface of the vortex.

[0040] The inner diameter of the water tank 101 is larger than the diameter of the blade 102a, which is beneficial for the blade 102a to stir without touching the inner wall of the water tank 101, thereby improving the stirring efficiency. Several blades 102a are evenly arranged in a circle around the axis of the rotating rod 102b, making the stirring water flow more uniform, further improving the stirring efficiency.

[0041] In summary, by setting the defoaming member 102c, when the worker starts the motor 103, the output end of the motor 103 drives the agitator 102 to rotate to stir the water, so that the medicine can fully mix the water, and the foam generated at the vortex is cut and broken by the high-speed rotation of the defoaming member 102c on the agitator 102. The advantage of this setting is that the defoaming member 102c cuts the foam, avoids the foam from adhering to the surface of the pipe and equipment to form an insulation layer, and improves the conduction efficiency.

[0042] Example 2

[0043] Reference Figures 1 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, a V-shaped spring piece 102c-5 is provided. The V-shaped spring piece 102c-5 utilizes the centrifugal force of the rotating rod 102b to make the movable piece 102c-3 close to the outer wall of the vortex after being thrown out, so that the blade 102c-4 cuts the foam on the outer wall of the vortex, further improving the effect of eliminating foam.

[0044] Specifically, the defoaming component 102c includes a hollow slider 102c-1, and a limiting block 102c-2 is arranged at the end of the hollow slider 102c-1, a V-shaped spring piece 102c-5 is arranged on the side of the limiting block 102c-2 away from the hollow slider 102c-1, a movable piece 102c-3 is arranged on the side of the V-shaped spring piece 102c-5 away from the limiting block 102c-2, and a blade 102c-4 is arranged on the side of the movable piece 102c-3 away from the V-shaped spring piece 102c-5.

[0045] The ends of the hollow slider 102c-1 passing through the sliding hole 102b-1 both abut against the inner wall of the sliding hole 102b-1, and the cross-section of the hollow slider 102c-1 is rectangular. The interior of the arc-shaped limit block 102c-2 is hollow, and the sides of the two limit blocks 102c-2 that are close to each other abut against the outer wall of the rotating rod 102b.

[0046] The side of the limit block 102c-2 away from the hollow slider 102c-1 is inclined outward from the bottom of the limit block 102c-2 to the top of the limit block 102c-2, and the side of the V-shaped spring piece 102c-5 close to the limit block 102c-2 is in conflict with the limit block 102c-2.

[0047] Under normal conditions, the ends of the two movable pieces 102c-3 are close to each other, the distance between the outer wall and the inner wall of the movable piece 102c-3 is short, the bottom height of the movable piece 102c-3 is lower than the bottom height of the limit block 102c-2, and the bottom of the movable piece 102c-3 is inclined downward toward the side close to the limit block 102c-2.

[0048] Among them, the hollow slider 102c-1 can slide in the sliding hole 102b-1 by utilizing buoyancy, which is beneficial for always being able to float on the water surface and cut the foam floating in the vortex according to the change of water volume. The side of the limit block 102c-2 away from the hollow slider 102c-1 is inclined outward from the bottom of the limit block 102c-2 to the top of the limit block 102c-2, which is beneficial for the outer wall of the defoaming component 102c to contact the outer wall of the vortex, thereby further improving the effect of the defoaming component 102c in cutting the foam on the outer wall of the vortex.

[0049] Under normal circumstances, the ends of the two movable sheets 102c-3 are close to each other, which is beneficial to increasing the contact area between the movable sheet 102c-3 and the foam on the outer wall of the vortex, thereby improving the cutting efficiency. The bottom height of the movable sheet 102c-3 is lower than the bottom height of the limit block 102c-2, and the bottom of the movable sheet 102c-3 is inclined downward toward the side close to the limit block 102c-2, which is beneficial when the inclination of the vortex is small. The foam at the vortex can be cut through the bottom of the movable sheet 102c-3 and the blade 102c-4 near the bottom, thereby improving the cutting efficiency.

[0050] In summary, by setting the V-shaped spring piece 102c-5, the worker can increase the efficiency of the agitator 102 stirring the water by increasing the rotation speed of the motor 103, so that the time for the agent to be fully mixed with the water is shortened. The inner diameter and inclination of the vortex where the rotating rod 102b is exposed to the water surface will increase immediately, and the V-shaped spring piece 102c-5 uses the centrifugal force of the rotating rod 102b to make the movable piece 102c-3 close to the outer wall of the vortex after being thrown out, so that the blade 102c-4 cuts the foam on the outer wall of the vortex, further improving the effect of eliminating foam.

[0051] Example 3

[0052] Reference Figure 1 , Figure 2 and Figure 7 This is the third embodiment of the utility model. Different from the previous embodiment, a scale 201a-1 is provided and the top of the medicine is aligned with the scale line of the scale 201a-1 to accurately control the outflowing medicine, so as to avoid the inability to effectively control the amount of medicine added during the addition of the medicine. Accurate use of the medicine not only saves the cost of the medicine, but also improves the effect of the scale agent.

[0053] Specifically, the dosing component 200 includes a medicine storage container 201 and a fixed plate 202 arranged at the bottom of the medicine storage container 201; and the support component 300 includes a base 301, an operating table 302 arranged on the top of the base 301, an L-shaped fixing frame 303 arranged on the top of the operating table 302, and a telescopic machine 304 arranged on the L-shaped fixing frame 303.

[0054] The medicine storage container 201 includes a medicine tank 201a, a medicine inlet nozzle 201b is arranged on the top of the medicine tank 201a, a scale 201a-1 is arranged on the medicine tank 201a, a medicine outlet pipe 201c is arranged at the bottom of the medicine tank 201a, a valve 201c-1 is arranged on the medicine outlet pipe 201c, and a universal wheel 301a is arranged at the bottom of the base 301.

[0055] A through hole is provided on the top of the medicine storage container 201 , and the telescopic end of the telescopic machine 304 is inserted into the through hole and fixedly connected to the fixed plate 202 , so that the bottom of the medicine storage container 201 contacts the top of the fixed plate 202 .

[0056] The diameter of the fixing plate 202 is larger than the diameter of the medicine storage container 201 , the medicine inlet nozzle 201 b is tilted upward toward the side away from the L-shaped fixing frame 303 , and the inner wall of the through hole contacts the outer wall of the telescopic machine 304 .

[0057] Among them, the diameter of the fixed plate 202 is larger than the diameter of the medicine storage container 201, which facilitates the placement of the medicine storage container 201. The inner wall of the through hole conflicts with the outer wall of the telescopic machine 304 to prevent the medicine storage container 201 from shaking and making noise when the support assembly 300 is moved.

[0058] In summary, by setting the scale 201a-1, workers can turn the valve 201c-1 to make the medicine in the medicine tank 201a flow out, and accurately control the flowing medicine by making the top of the medicine flush with the scale line of the scale 201a-1, so as to avoid the inability to effectively control the amount of medicine added. Accurate use of medicine not only saves the cost of medicine, but also improves the effect of the scale agent.
