Description

Technical Field

[0001] This application relates to the field of proportioning device technology, specifically to a proportioning device for scale inhibitors. Background Technology

[0002] Scale inhibitors are agents that can disperse sparingly soluble inorganic salts in water, prevent or interfere with the precipitation and scaling of sparingly soluble inorganic salts on metal surfaces, and maintain good heat transfer performance of metal equipment. They can remove scale and prevent its formation, improve heat exchange efficiency, reduce electricity or fuel consumption, and water treatment can also reduce sewage discharge and improve water utilization.

[0003] An existing patent (publication number: CN214635645U) discloses a scale inhibitor mixing device for easy adjustment of the ratio, including a sealing cap. A fixing frame and a stirring motor are fixedly mounted on the upper surface of the sealing cap. Several ratio adjustment mechanisms are fixedly mounted on the fixing frame. Each ratio adjustment mechanism includes a first connecting pipe fixedly connected to the fixing frame, a first water pipe switch valve installed on the first connecting pipe, a reagent storage tank fixedly mounted at the upper end of the first connecting pipe, a quantitative temporary storage cylinder fixedly mounted at the lower end of the first connecting pipe, and a second connecting pipe fixedly mounted at the lower end of the quantitative temporary storage cylinder. A second water pipe switch valve is installed on the second connecting pipe. This invention's mixing device can quantitatively store multiple reagents and use quantitative reagent solutions according to actual needs. Simultaneously, multiple quantitative temporary storage cylinders can independently store reagents, allowing for convenient preparation and use according to different ratio requirements.

[0004] Although the device in the aforementioned comparative document can be used to adjust the dosage according to different ratio requirements, the agent at the bottom may settle during mixing, resulting in uneven mixing of the agent. In order to solve the above problem, a scale inhibitor mixing device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a scale inhibitor mixing device that can reduce the probability of bottom deposition of the agent, improve the uniformity of mixing of various agents, and solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a scale inhibitor mixing device, comprising a mixing tank, a top cover, a mixing component, and a mixing component. The mixing component includes a first servo motor fixedly connected to the bottom of the mixing tank and a spiral blade fixedly connected to the output shaft end of the first servo motor. The outer surface of the spiral blade is provided with uniformly distributed through holes. A first crossbar is fixedly connected to the bottom end of the spiral blade. A first scraper is fixedly connected to the bottom surface of the first crossbar. Rotary rods are rotatably sleeved at both ends of the first crossbar. A second scraper is fixedly connected to the outer surface of each of the rotating rods.

[0007] Each of the rotating rods is fixedly connected to a planar gear at its top end. A gear ring is fixedly connected to the inner wall of the top of the mixing box. Both planar gears mesh with the gear ring. A second servo motor is fixedly connected to the upper surface of the top cover. A second crossbar is fixedly connected to the output end of the second servo motor. Both ends of the second crossbar are fixedly connected to stirring components.

[0008] Through the above scheme, a scale inhibitor proportioning device can achieve quantitative proportioning of scale inhibitors through the proportioning components. The mixing components can effectively reduce the probability of multiple agents depositing, and also reduce the probability of multiple agents adhering to the inner wall of the mixing tank, thus affecting the mixing quality. Driving the first servo motor can rotate the spiral blades and the first crossbar. When the spiral blades rotate, the agent at the bottom of the mixing tank is conveyed upward, thereby reducing the probability of agent deposition. When the first crossbar rotates, it can cause the rotating rod and the second scraper to rotate through the planar gear and the gear ring, thus scraping off the agent adhering to the inner wall of the mixing tank. Then, the second servo motor is started to drive the second crossbar and the stirring components to rotate, which can cooperate with the spiral blades and the second scraper to achieve the effect of shearing, stirring and mixing, improving the mixing quality and benefiting the production of scale inhibitors.

[0009] Furthermore, the top cover is bolted to the top of the mixing chamber, which includes an outer shell, the inner side of which is fixedly provided with a self-lubricating graphene coating.

[0010] The above scheme defines the relationship between the top cover and the mixing chamber, facilitating regular cleaning of the interior of the mixing chamber. The self-lubricating graphene coating reduces the coefficient of friction on the inner wall of the outer shell, thereby effectively reducing the amount of scale buildup.

[0011] Furthermore, the proportioning component includes multiple storage cylinders fixedly connected to the top of the top cover. The output end of each storage cylinder is connected to a first conveying pipe, the bottom end of each first conveying pipe is connected to a metering cylinder, the bottom end of each metering cylinder is connected to a second conveying pipe, and the bottom end of each second conveying pipe is connected to the interior of the mixing box.

[0012] With the above scheme, multiple agents can be stored in multiple storage cylinders. Then, the agents in the storage cylinders are transported to the metering cylinders for quantitative storage through the first delivery pipe. Then, the agents in the metering cylinders are quantitatively transported to the mixing tank through the second delivery pipe for mixing. This is beneficial for the precise preparation of scale inhibitors.

[0013] Furthermore, a first solenoid valve is installed on each segment of the first delivery pipe, and a second solenoid valve is installed on each segment of the second delivery pipe.

[0014] The above scheme allows for more precise adjustment of the quantitative delivery of the medicine by using the first and second solenoid valves.

[0015] Furthermore, the first scraper is adapted to the inner bottom wall of the mixing chamber, the second scraper is adapted to the inner side wall of the mixing chamber, the spiral blade is located between the two stirring components, and the two rotating rods are respectively located on the outside of the two stirring components.

[0016] The above scheme defines the relationship between the first scraper, the second scraper, and the mixing chamber, which reduces the likelihood of the agent adhering to the inner wall of the mixing chamber, thereby improving the uniformity of mixing multiple agents. By defining the relationship between the spiral blades, the rotating rod, and the stirring components, various stirring effects can be achieved, thereby improving the mixing quality of multiple agents.

[0017] Furthermore, a controller is fixedly connected to the outer surface of the mixing chamber, and the electrical components inside the proportioning component and the mixing component are all electrically connected to the controller.

[0018] The above solution allows for convenient control of the electrical components within the proportioning and mixing components via a specially designed controller, simplifying the operational process.

[0019] Furthermore, four L-shaped support columns are fixedly connected to the outer surface of the mixing box, and an anti-slip pad is fixedly connected to the bottom end of each L-shaped support column.

[0020] The above solution, with its L-shaped support column, allows the device to be placed more stably on the contact surface.

[0021] Furthermore, the bottom of the mixing tank is connected to a drain pipe, and the top of the mixing tank is connected to a water injection pipe.

[0022] The above solution allows for easy discharge of the scale inhibitor that has been mixed inside the mixing tank to the outside via the drainage pipe, and easy injection of cleaning fluid into the mixing tank via the water injection pipe, thus facilitating regular cleaning of the mixing tank.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This scale inhibitor mixing device, through its mixing components, enables quantitative mixing of the scale inhibitor. Its mixing components effectively reduce the likelihood of various agents depositing and adhering to the inner wall of the mixing tank, thus minimizing the impact on mixing quality. A first servo motor drives the spiral blades and first crossbar to rotate. When the spiral blades rotate, the agent at the bottom of the mixing tank is conveyed upwards, further reducing the likelihood of deposits. The rotation of the first crossbar, via a planar gear and gear ring, causes the rotating rod and second scraper to rotate, scraping off the agent adhering to the inner wall of the mixing tank. Then, the second servo motor drives the second crossbar and stirring components to rotate, working in conjunction with the spiral blades and second scraper to achieve a shearing and mixing effect, improving mixing quality and benefiting scale inhibitor production.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a scale inhibitor mixing device includes a mixing tank 1, a top cover 2, a mixing component 3, and a mixing component 4. The top cover 2 is bolted to the top of the mixing tank 1. The mixing tank 1 includes a shell 101, and a self-lubricating graphene coating 102 is fixedly provided on the inner side of the shell 101, defining the relationship between the top cover 2 and the mixing tank 1, facilitating regular cleaning of the interior of the mixing tank 1. The self-lubricating graphene coating 102 reduces the coefficient of friction of the inner wall of the shell 101, thereby effectively reducing the amount of scale adhesion. The mixing component 3 includes multiple storage cylinders 301 fixedly connected to the top of the top cover 2. The output end of each storage cylinder 301 is connected to a first delivery pipe 302, and the bottom end of each first delivery pipe 302 is connected to a metering cylinder 303. The bottom end of each cylinder 303 is connected to a second delivery pipe 304, and the bottom end of each second delivery pipe 304 is connected to the interior of the mixing box 1. Multiple agents can be stored in multiple storage cylinders 301 respectively. Then, the agents in the storage cylinders 301 are delivered to the metering cylinders 303 for metered storage through the first delivery pipe 302. Then, the agents in the metering cylinders 303 are delivered to the mixing box 1 for mixing through the second delivery pipes 304. This is beneficial for the precise preparation of scale inhibitors. Each section of the first delivery pipe 302 is equipped with a first solenoid valve 305, and each section of the second delivery pipe 304 is equipped with a second solenoid valve 306. The first solenoid valve 305 and the second solenoid valve 306 can be used to more accurately adjust the metered delivery of the agents.

[0034] Please see Figure 2 , Figure 3 and Figure 4The mixing component 4 includes a first servo motor 401 fixedly connected to the bottom of the mixing chamber 1 and a spiral blade 402 fixedly connected to the output shaft end of the first servo motor 401. The outer surface of the spiral blade 402 has evenly distributed through holes 403. When the first servo motor 401 starts, it drives the spiral blade 402 to rotate. When the spiral blade 402 rotates, it can lift the reagent at the bottom of the mixing chamber 1 upwards through the through holes 403 on its surface, effectively preventing sedimentation and thus improving the mixing quality of the various reagents. A first crossbar 404 is fixedly connected to the bottom end, and a first scraper 405 is fixedly connected to the bottom surface of the first crossbar 404. Rotating rods 406 are rotatably sleeved at both ends of the first crossbar 404. A second scraper 407 is fixedly connected to the outer surface of each rotating rod 406. When the spiral blade 402 rotates, the first scraper 405 and rotating rod 406 can be driven to rotate through the first crossbar 404. When the first scraper 405 rotates, it can scrape off the agent adhering to the bottom wall of the mixing box 1, thereby enabling multiple agents to be evenly mixed inside the mixing box 1.

[0035] Please see Figure 3 , Figure 4 and Figure 5 Each rotating rod 406 has a planar gear 408 fixedly connected to its top end. A gear ring 409 is fixedly connected to the inner wall of the top of the mixing tank 1. Both planar gears 408 mesh with the gear ring 409. When the first crossbar 404 rotates, the rotating rod 406 can be rotated through the planar gears 408 and the gear ring 409. When the rotating rod 406 rotates, the second scraper 407 can scrape off the agent adhering to the inner wall of the mixing tank 1, so that the agent inside the mixing tank 1 can be more fully mixed, thereby improving the production quality of the scale inhibitor. A second servo motor 410 is fixedly connected to the upper surface of the top cover 2. A second crossbar 411 is fixedly connected to the output end of the second servo motor 410. Both ends of the second crossbar 411 are fixedly connected to the stirring assembly 412. When the second servo motor 410 is started, it will drive the second crossbar 411. 1. The stirring assembly 412 rotates in the opposite direction to the rotation of the spiral blade 402, thus forming a shear force field inside the mixing chamber 1 to achieve multi-directional turbulent mixing. The first scraper 405 is adapted to the inner bottom wall of the mixing chamber 1, and the second scraper 407 is adapted to the inner side wall of the mixing chamber 1. The spiral blade 402 is located between the two stirring assemblies 412, and the two rotating rods 406 are located on the outer sides of the two stirring assemblies 412 respectively, defining the relationship between the first scraper 405, the second scraper 407 and the mixing chamber 1. This can reduce the probability of the agent adhering to the inner wall of the mixing chamber 1, thereby improving the uniformity of the mixing of multiple agents. By defining the relationship between the spiral blade 402, the rotating rod 406 and the stirring assembly 412, various mixing effects can be achieved, thereby improving the mixing quality between multiple agents.

[0036] Please see Figure 1 , Figure 2 and Figure 3 A controller 5 is fixedly connected to the outer surface of the mixing tank 1. The electrical components inside the proportioning component 3 and the mixing component 4 are all electrically connected to the controller 5. The controller 5 can conveniently control the electrical components inside the proportioning component 3 and the mixing component 4, simplifying the operation process. Four L-shaped support columns 6 are fixedly connected to the outer surface of the mixing tank 1. Each L-shaped support column 6 has an anti-slip pad fixedly connected to its bottom end. The L-shaped support columns 6 can make the device more stable on the contact surface. The bottom of the mixing tank 1 is connected to a drain pipe 7, and the top of the mixing tank 1 is connected to a water injection pipe 8. The drain pipe 7 can conveniently discharge the scale inhibitor that has been mixed inside the mixing tank 1 to the outside. The water injection pipe 8 can conveniently introduce cleaning fluid into the mixing tank 1, thus facilitating the regular cleaning of the interior of the mixing tank 1.

[0037] In this embodiment, a scale inhibitor mixing device can achieve quantitative mixing of scale inhibitors through the mixing component 3. The mixing component 4 can effectively reduce the probability of multiple agents depositing and also reduce the probability of multiple agents adhering to the inner wall of the mixing tank 1, thus affecting the mixing quality. Driving the first servo motor 401 can rotate the spiral blade 402 and the first crossbar 404. When the spiral blade 402 rotates, it can transport the agent at the bottom of the mixing tank 1 upward, thereby reducing the probability of agent deposition. When the first crossbar 404 rotates, it can rotate the rotating rod 406 and the second scraper 407 through the planar gear 408 and the gear ring 409, thus scraping off the agent adhering to the inner wall of the mixing tank 1. Then, the second servo motor 410 is started to drive the second crossbar 411 and the stirring component 412 to rotate, which can cooperate with the spiral blade 402 and the second scraper 407 to achieve the effect of shearing, stirring and mixing, improving the mixing quality and benefiting the production of scale inhibitors.

[0038] The working principle of the above embodiment is as follows: First, different reagents are stored in multiple storage cylinders 301 in the proportioning component 3. The controller 5 activates the first solenoid valve 305 and the second solenoid valve 306. After the reagents are temporarily stored in the metering cylinder 303 through the first delivery pipe 302, they are precisely injected into the mixing box 1 through the second delivery pipe 304. During the mixing stage, the first servo motor 401 drives the spiral blade 402 to rotate. The through holes 403 on the surface of the spiral blade 402 lift the reagents at the bottom of the mixing box 1 upwards, effectively preventing sedimentation. The first crossbar 404 fixedly connected to the bottom end of the spiral blade 402 drives the first scraper 405 to rotate. At the same time, the planar gear 408 at the top of the rotating rod 406 rotatably sleeved at both ends of the first crossbar 404 meshes with the toothed ring 409 fixed to the inner wall of the top of the mixing box 1, driving the rotating rod. 406 and the second scraper 407 rotate along the inner wall of the mixing tank 1 to scrape off the attached agent. At this time, the second servo motor 410 starts, driving the second crossbar 411 and the stirring assembly 412 to rotate at high speed, forming a shear force field with the spiral blade 402 and the second scraper 407 to achieve multi-directional turbulent mixing. During the mixing process, the self-lubricating graphene coating 102 on the inner wall of the mixing tank 1 reduces friction and further reduces agent residue. After the mixing is completed, the scale inhibitor is discharged through the drain pipe 7. During cleaning, the cleaning fluid is introduced through the water injection pipe 8. The first scraper 405 and the second scraper 407 work together to quickly remove residue. The entire process is coordinated by the controller 5 with the electrical components of the proportioning assembly 3 and the mixing assembly 4 to achieve automated proportioning and cleaning, significantly improving the mixing uniformity and maintenance efficiency. It is suitable for the production of high-precision scale inhibitors.
