Description

Technical Field

[0001] This utility model relates to the field of scale inhibitor mixing technology, specifically to a scale inhibitor mixing device. Background Technology

[0002] Scale inhibitors are typically composed of multiple chemical components. For example, common scale inhibitors include organophosphonic acids and polycarboxylic acids. Mixing these components allows them to come into full contact and exert a synergistic effect. Organophosphonic acids can form stable complexes with calcium and magnesium ions in water, preventing them from precipitating and forming scale; polycarboxylic acids can form a protective film on equipment surfaces, inhibiting scale adhesion. When mixed, this synergistic effect more effectively prevents scale formation on the surfaces of pipes, heat exchangers, and other equipment. Compared to single-component scale inhibitors, the scale inhibition effect of a mixed agent is significantly improved.

[0003] Chinese patent CN219647234U discloses a mixing device for preparing scale inhibitors. The device includes a housing and a stirring shaft positioned in the middle of the housing. A fancy stirring mechanism, a plate stirring mechanism, and a bottom disc turbine stirring mechanism are fitted around the stirring shaft. All three mechanisms are fixedly connected to the stirring shaft. A feed pipe is sealed on one side of the upper end of the housing. A drive motor is located in the middle of the upper part of the housing and is connected to the stirring shaft via a coupling. A discharge pipe is located in the middle of the bottom of the housing. An air pump is located on one side of the housing and is sealed to the housing via an air inlet pipe. A pressure relief valve is located on the side of the housing. This invention can thoroughly mix and stir materials, resulting in more uniform mixing at the bottom, improving product quality, increasing production efficiency, and ensuring safe use.

[0004] Existing scale inhibitor mixing devices typically only use a stirring shaft or stirring fan blades to mix the scale inhibitor. Scale inhibitors with different components may undergo chemical reactions during the mixing process, producing certain precipitates. Simple stirring and mixing cannot separate these precipitates. The precipitates mixed in the scale inhibitor will affect the quality of the scale inhibitor. In addition, the liquid flow is faster around the stirring shaft and slower in areas away from the stirring shaft, making it difficult for the scale inhibitor components to be fully mixed in these areas.

[0005] To address the above problems, a scale inhibitor mixing device is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1 to 8This utility model discloses a scale inhibitor mixing device, comprising a scale inhibitor mixing tank 1, an impurity filtration assembly 2 installed inside the scale inhibitor mixing tank 1, the impurity filtration assembly 2 including an impurity filtration plate 201, and the impurity filtration plate 201 being fixedly connected to the inner wall of the scale inhibitor mixing tank 1, the impurity filtration plate 201 having uniformly distributed filter holes 202 inside, the top of the impurity filtration plate 201 being fixedly connected to an inlet 203, and the top of the inlet 203 being fixedly connected to an inlet cylinder 204, the inlet cylinder 204 having a spring 205 nested inside, the bottom end of the spring 205 being fixedly connected to the inlet cylinder 204, and the top of the spring 205 being fixedly connected to an anti-flow baffle 206, the opening size of the inlet 203 gradually decreasing from bottom to top, the inlet 203 being connected to the inlet cylinder 204, and the outer diameter of the anti-flow baffle 206 being larger than the inner diameter of the inlet cylinder 204.

[0031] When the scale inhibitor mixing tank 1 is in the inverted state, the impurity filtration assembly 2 is located in the lower part of the scale inhibitor mixing tank 1. The scale inhibitor material flows into the inlet cylinder 204 through the upward-facing inlet 203. Under the action of liquid pressure, it moves downward against the anti-flow baffle 206, stretching the spring 205. At this time, the anti-flow baffle 206 disengages from the port of the inlet cylinder 204, and the material can flow downward through the inlet cylinder 204. When the scale inhibitor mixing tank 1 is in the upright state again, the impurity filtration assembly 2 is flipped to the top. At this time, under the action of the spring 205, the anti-flow baffle 206 is pulled to cover the port of the inlet cylinder 204, blocking it. At this time, under the action of its own gravity, the scale inhibitor flows downward through the filter hole 202. Some impurities larger than the pore size of the filter hole 202 are filtered out and cannot participate in the subsequent mixing.

[0032] An anti-clogging component 3 is installed at the bottom of the impurity filter plate 201. The anti-clogging component 3 is used to unclog the filter holes 202. The anti-clogging component 3 includes a support baffle 301, and the support baffle 301 is slidably connected to the scale inhibitor mixing tank 1. A unclogging nail 302 is fixedly connected to the top of the support baffle 301, and a tip 303 is fixedly connected to the top of the unclogging nail 302. The unclogging nail 302 corresponds one-to-one with the filter holes 202. A through hole 305 is opened on the side of the support baffle 301. A limiting shaft 306 passes through the inside of the through hole 305, and the limiting shaft 306 is slidably connected to the support baffle 301. The top of the limiting shaft 306 is fixedly connected to the impurity filter plate 201, and an anti-detachment plate 307 is fixedly connected to the bottom of the limiting shaft 306. The outer diameter of the anti-detachment plate 307 is larger than the inner diameter of the through hole 305.

[0033] In the upright position, the support baffle 301 moves downward along the limiting shaft 306 under its own weight and the impact of the liquid, and there is a certain gap between it and the impurity filter plate 201. The unblocking nails 302 are disengaged from the filter holes 202, allowing the scale inhibitor liquid to flow downward through the filter holes 202. After flipping, the support baffle 301 is located above the impurity filter plate 201. Under its own weight and the liquid pressure, the support baffle 301 moves towards the impurity filter plate 201 with each unblocking nail 302 and tip 303. The unblocking nails 302 and tip 303 are inserted into the filter holes 202 to unblock them. Each set of flipping completes one unblocking.

[0034] The scale inhibitor mixing tank 1 is also equipped with a mixing component 4. The mixing component 4 includes a servo motor 401, which is installed at the bottom of the scale inhibitor mixing tank 1. The output end of the servo motor 401 is fixedly connected to a rotating shaft 402, and the rotating shaft 402 is rotatably connected to the scale inhibitor mixing tank 1. The part of the rotating shaft 402 inserted into the scale inhibitor mixing tank 1 is equipped with a perforated plate 403 and a stirring blade 405. The perforated plate 403 and the stirring blade 405 are spaced apart. The rotating shaft 402 and the perforated plate 403 are rotatably connected, and the perforated plate 403 is fixedly connected to the inner wall of the scale inhibitor mixing tank 1. The rotating shaft 402 and the stirring blade 405 are fixedly connected. The perforated plate 403 is uniformly provided with diversion mixing holes 404.

[0035] The perforated plate 403 plays a role in dividing and guiding the liquid flow during this inverted mixing process. When the scale inhibitor mixing tank 1 is inverted and shaken, the liquid is divided into multiple small streams through the various diversion mixing holes 404, which increases the chance of contact between different components. The rotating shaft 402, which rotates with the stirring blades 405, further enhances the local mixing effect, so that the scale inhibitors of different components can be more evenly dispersed in the entire mixing tank, achieving a good mixing effect.

[0036] A tilting assembly 5 is installed on the outside of the scale inhibitor mixing tank 1. The tilting assembly 5 includes a drive shaft 501, which is fixedly connected to the side of the scale inhibitor mixing tank 1. A first support column 502 is rotatably connected to the outside of the drive shaft 501. A stepper motor 503 is installed on the outer wall of the first support column 502, and the output end of the stepper motor 503 is fixedly connected to the drive shaft 501. A driven shaft 504 is fixedly connected to the side of the scale inhibitor mixing tank 1 away from the drive shaft 501, and a second support column 505 is rotatably connected to the end of the driven shaft 504. A device base plate 506 is fixedly connected to the bottom end of the second support column 505, and the device base plate 506 is fixedly connected to the first support column 502.

[0037] The stepper motor 503 drives the scale inhibitor mixing tank 1 to rotate via the active rotating shaft 501. The up-and-down shaking method makes the liquid in the scale inhibitor mixing tank 1 turn over as a whole, avoiding the problem of insufficient mixing in local areas. Good mixing effect can be achieved in the upper, middle and lower parts of the tank.

[0038] The top of the scale inhibitor mixing tank 1 is threaded with a spiral sealing cap 7, and a sealing ring 6 is fixedly connected to the inner wall of the spiral sealing cap 7. The sealing ring 6 and the scale inhibitor mixing tank 1 are tightly fitted. After the spiral sealing cap 7 is turned off, the scale inhibitor mixing tank 1 can be opened, and various raw materials can be added into the interior of the scale inhibitor mixing tank 1 for mixing. After mixing, the filtered impurities are isolated between the impurity filter plate 201 and the spiral sealing cap 7. The spiral sealing cap 7 can be opened to clean the impurities.
