Description

Technical Field

[0001] This invention relates to the field of dispersant preparation technology, specifically to a device for preparing scale inhibitors and dispersants for circulating water systems. Background Technology

[0002] Wastewater reuse has significant environmental and economic benefits and is a purely green and environmentally friendly advanced technology. However, due to the complex sources and different treatment processes of industrial wastewater discharge, the quality of treated water varies greatly and can be quite poor. The inherent characteristics of treated wastewater can have a very negative impact on the circulating water system. If not handled carefully, it can seriously affect the treatment effect of the circulating water system, thereby seriously affecting the operation of the production system, causing production stoppages or equipment damage, and severely restricting the scope and amount of wastewater reuse.

[0003] Many companies use dispersants to control trace substances in their circulating water systems. However, due to the unstable water quality and numerous impurity ions during the treatment of industrial wastewater into recycled water, existing dispersants in the industry cannot effectively control trace substances in circulating water systems, such as phosphate, calcium and magnesium ions, alkalinity, chloride ions, and various bacteria and algae that cause severe scaling and corrosion. Therefore, there is an urgent need for a scale inhibitor and dispersant for circulating water systems. For example, the dispersant and preparation method for recycled water from industrial wastewater (publication number CN102504080A) effectively prevents the formation of scale deposits by adsorbing and chelating inorganic scaling microcrystals such as calcium carbonate and calcium phosphate, as well as organic microparticles in the water. This is particularly suitable for the characteristics of recycled water after wastewater treatment, which is high in hardness, high in alkalinity, and contains many complex organic substances. It effectively inhibits scale and disperses scale in recycled water systems, achieving good and long-lasting treatment results.

[0004] However, drawbacks remain: the high-level tank and reaction vessel used in the aforementioned patent have a relatively tight fit, which inevitably leads to oversights by the user during actual use. This results in a low tolerance for error in the final product, affecting its usability. Furthermore, the lack of coordination between the multiple devices makes them occupy a large area and inconvenient to use. Therefore, there is an urgent need for an integrated preparation device for this preparation method to address these inconveniences. Summary of the Invention

The top of the third gear is provided with a groove, and the inner side wall of the groove is provided with a ratchet tooth. The bottom of the third rotating shaft is provided with a pawl that engages with the ratchet tooth.

[0012] Preferably, the reaction chamber is provided with a fourth rotating shaft that extends into the second chamber, and the bottom of the fourth rotating shaft is provided with a stirring blade. The second chamber is equipped with a second motor, and the output end of the second motor is connected to a second bevel gear.

[0016] Four different raw materials are placed into four separate feeding cylinders, and then the driving component stirs the raw materials inside the four feeding cylinders in a unified manner, which effectively saves time. After stirring, the driving component is used to put the raw materials inside the four feeding cylinders into the reaction chamber one by one for reaction. The whole process does not require manual operation, and the step-by-step effect is good. This means that only one device is needed to prepare the raw materials when making dispersants. It has a small footprint and is more convenient to use. Attached Figure Description

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] Please see Figures 1-8 A device for preparing a scale inhibitor and dispersant for a circulating water system includes a device box 1. A cover 2 is connected to the top of the device box 1 via a flange. The device box 1 has a cylindrical structure. After the cover 2 is connected to the top of the device box 1, the cover 2 and the device box 1 together form a sealed cylindrical shape. Specifically, as shown... Figure 1 ;

[0035] The device box 1 has a first chamber 101, a second chamber 102 and a third chamber 103 arranged from top to bottom. The third chamber 103 includes a reaction chamber 1032 and a condensation chamber 1031 located outside the reaction chamber 1032. The bottom of the reaction chamber 1032 is provided with a discharge port 21 and the bottom of the condensation chamber 1031 is provided with a water outlet 22. Valves are provided inside both the discharge port 21 and the water outlet 22.

[0036] The first chamber 101 is equipped with a connecting cylinder 3, and a central cavity 36 is formed at the center of the connecting cylinder 3. Four circular cavities 35 are evenly formed outside the central cavity 36 inside the connecting cylinder 3. Each of the four circular cavities 35 is equipped with a distributing cylinder 4. A first rotating shaft 5 is provided inside the distributing cylinder 4 and extends to the outside of the distributing cylinder 4. A stirring plate 6 is connected to the outside of the first rotating shaft 5. The first chamber 101 is also equipped with a drive assembly 7 for driving the first rotating shaft 5 to rotate along its own axis. The drive assembly 7 can drive the first rotating shaft 5, so that the first rotating shaft 5 drives the stirring plate 6 to rotate. The top of the distributing cylinder 4 is equipped with a feed hole and a valve. Material is fed into the distributing cylinder 4 through the feed hole. Then, the driving assembly 7 is used to rotate the stirring plate 6 to facilitate the stirring of the material inside the distributing cylinder 4.

[0037] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the drive assembly 7 includes a second rotating shaft 704 located inside the first chamber 101 and extending to the top of the device box 1, and a first motor 705 located above the device box 1 and driving the second rotating shaft 704 to rotate along its own axis. A rotating cover 701 is provided at the bottom of the second rotating shaft 704, and an inner ring tooth 702 is provided on the inner side wall of the rotating cover 701. A first gear 703 that meshes with the inner ring tooth 702 is provided at the top of the first rotating shaft 705. In use, by starting the first motor 705, the first motor 705 drives the second rotating shaft 704 to rotate, thereby causing the rotating cover 701 to rotate. Since the inner ring tooth 702 inside the rotating cover 701 meshes with all four first gears 703, the rotation of the rotating cover 701 can cause the four first gears 703 to rotate synchronously, thereby enabling the stirring plates 6 inside the four dispensing cylinders 4 to rotate synchronously, ensuring that the materials inside the four dispensing cylinders 4 can be stirred synchronously.

[0038] Please refer to this carefully. Figures 2-8 As shown, a fixing block 34 is also provided on the inner wall of the first chamber 101, and the fixing block 34 is provided with an inclined surface 341 and an arc-shaped surface 342. A connecting rod 37 is provided on the outside of the distributing cylinder 4, extending to the outside of the connecting cylinder 3, and the connecting rod 37 is connected to the connecting cylinder 3 by a first spring 38. A magnet 27 is provided at the center of the bottom end of the connecting cylinder 3, and a feeding hole 28 is opened at the bottom of the connecting cylinder 3 outside the magnet 27. The bottom of the distributing cylinder 4 is provided with a first hole 29 and a second hole 30 from top to bottom, and a third hole 31 is opened at the center of the bottom of the distributing cylinder 4. An iron is provided inside the third hole 31. Block 32, and the top of the iron block 32 is connected to the sealing block 33 located inside the first hole 29 via a connecting rod; the inner wall of the first chamber 101 is also rotatably connected to the third gear 11 and the third rotating shaft 9 via a connecting plate; the outer side of the connecting cylinder 3 is provided with the second outer ring tooth 12 that meshes with the third gear 11; the top of the third rotating shaft 9 is coaxially connected to the second gear 10; the outer side of the rotating cover 701 is provided with the first outer ring tooth 8 that meshes with the second gear 10; the top of the third gear 11 is provided with a groove 13, and the inner wall of the groove 13 is provided with a ratchet 14; the bottom of the third rotating shaft 9 is provided with a pawl 15 that engages with the ratchet 14.

[0039] In practical use, if the first motor 705 is a stepper motor, when the first motor 705 drives the second rotating shaft 704 to rotate counterclockwise, the first rotating shaft 705 drives the stirring plate 6 to rotate, thereby stirring the material inside the dispensing cylinder 4. Simultaneously, the rotation of the rotating cover 701 causes its outer first ring gear 8 to rotate, which in turn causes the second gear 10 to drive the third rotating shaft 9 to rotate. The rotation of the third rotating shaft 9 then drives the pawl 15 to rotate. Figure 8It can be seen that the counterclockwise rotation of the second rotating shaft 704 causes the third rotating shaft 9 to rotate clockwise. The clockwise rotation of the third rotating shaft 9 prevents the pawl 15 and the ratchet 14 from engaging (the pawl 15 is a flexible metal structure that can bend appropriately). When the connecting cylinder 3 needs to rotate, the second rotating shaft 704 drives the rotating cover 701 to rotate clockwise, which in turn causes the third rotating shaft 9 to rotate counterclockwise. The counterclockwise rotation of the third rotating shaft 9 causes the pawl 15 and the ratchet 14 to engage, causing the third gear 11 to rotate. Since the third gear 11 meshes with the second outer ring tooth 12 outside the connecting cylinder 3, the connecting cylinder 3 can rotate. When the connecting cylinder 3 rotates, the four internal distributing cylinders 4 will rotate accordingly. Figure 4 As shown, if the connecting cylinder 3 drives the connecting rod 37 and the distributing cylinder 4 to rotate clockwise at this time, the connecting rod 37 on the left side will first contact the inclined surface 341 on the fixed block 34. The connecting rod 37 will compress the first spring 38 and cause the connecting rod 37 to drive the distributing cylinder 4 to disengage from the circular cavity 35 and move towards the middle cavity 36. When it moves to... Figure 4 The process stops at the dotted line position. At this point, the distributing cylinder 4 is exactly at the center of the entire connecting cylinder 3. Figure 3 and Figure 5 When the distributing cylinder 4 moves to the center position, the magnet 27 repels the iron block 32 at the bottom of the distributing cylinder 4, causing the iron block 32 to drive the sealing block 33 to rise. Since the side of the sealing block 33 is inclined, when the sealing block 33 rises, the side of the first hole 29, which cooperates with the sealing block 33, is also inclined. Therefore, the rise of the sealing block 33 can open the first hole 29, allowing the material inside the distributing cylinder 4 to fall through the first hole 29, the second hole 30, and the discharge hole 28. In this way, by driving the connecting cylinder 3 to rotate slowly, the material inside each distributing cylinder 4 can be discharged in sequence, ensuring the continuity of material discharge.

[0040] Please refer to this carefully. Figure 2 As shown, a fourth rotating shaft 16 is provided inside the reaction chamber 1032, extending into the second chamber 102. A stirring blade 17 is located at the bottom of the fourth rotating shaft 16. A second motor 20 is installed inside the second chamber 102, and a second bevel gear 19 is connected to the output end of the second motor 20. A first bevel gear 18, which is fitted onto the top of the fourth rotating shaft 16, interacts with the second bevel gear 19. The second motor 20 drives the second bevel gear 19 to rotate, causing the first bevel gear 18 to drive the fourth rotating shaft 16 and the stirring blade 17 to rotate, thus facilitating the stirring of the materials inside the reaction chamber 1032.

[0041] Please refer to this carefully. Figure 2As shown, the inner top of the second chamber 102 is provided with a cover 24 communicating with the discharge hole 28. A negative pressure pump 23 is also provided inside the second chamber 102, with its inlet end connected to an inlet pipe 25 communicating with the cover 24, and its outlet end connected to an outlet pipe 26 communicating with the inside of the reaction chamber 1032. When the material in the dispensing cylinder 4 passes through the discharge hole 28, it enters the inside of the cover 24. The negative pressure pump 23 can draw the material inside the cover 24 into the inside of the reaction chamber 1032, preventing material accumulation and making it more convenient to use.

[0042] Please refer to this carefully. Figure 5 As shown, a fixed box 39 is provided on the top of the dispensing cylinder 4, and a piston 40 is slidably disposed inside the fixed box 39. A trapezoidal block 42 is provided on the side of the piston 40 facing the first rotating shaft 5, extending through to the outside of the fixed box 39. A connecting ball 43 that cooperates with the trapezoidal block 42 is provided on the first rotating shaft 5. The side of the piston 40 away from the trapezoidal block 42 is connected to the inner wall of the fixed box 39 by a second spring 41. An air inlet pipe 45 and an air outlet pipe 44 that communicate with the inside of the fixed box 39 are provided on the outside of the fixed box 39. The end of the air inlet pipe 45 extends into the inside of the dispensing cylinder 4. A one-way valve is provided inside both the air inlet pipe 45 and the air outlet pipe 44. When the first rotating shaft 5 rotates, the connecting ball 43 rotates accordingly. Since both the front and rear end faces of the trapezoidal block 42 are inclined, regardless of how the connecting ball 43 rotates, it can engage with the front and rear end faces of the trapezoidal block 42, causing the trapezoidal block 42 to be pressed into the interior of the fixing box 39. When the connecting ball 43 is not in contact with the trapezoidal block 42, the trapezoidal block 42 returns to its original position under the action of the second spring 41. This process repeats, allowing the piston 40 to reciprocate left and right. When the piston 40 moves from left to right, the intake pipe... The one-way valve inside 45 opens, allowing the gas inside the dispensing cylinder 4 to be drawn into the fixed box 39. When the piston 40 moves from right to left, the one-way valve inside the exhaust pipe 44 opens, expelling the gas that was previously drawn into the fixed box 39 from the outside of the device box 1. This process repeats, allowing all the gas inside the dispensing cylinder 4 to be extracted. It should be noted that when the pressure inside the dispensing cylinder 4 is low, the second spring 41 will not return to its original deformation. At this time, the trapezoidal block 42 will no longer contact the connecting ball 43, and the piston 40 will no longer reciprocate to draw in air.

[0043] Working principle: Specifically, during use, first separate the cover 2 from the device box 1, then place the deionized production water, isopropanol, and maleic anhydride into one of the dispensing cylinders 4. Figure 4 (In the base coat dispensing cylinder 4); place methyl acrylate and acrylic acid into the inside of another dispensing cylinder 4 ( Figure 4 (In the No. 1 high-level tank); place AMPS and deionized production water into the interior of another dispensing cylinder 4 ( Figure 4(In the No. 2 high-level tank); place the initiator and deionized production water into the interior of another dispensing cylinder 4 ( Figure 4 (in the No. 3 high-level tank);

[0044] Turn on the drive component 7 and use the drive component 7 to stir the raw materials inside the four dispensing cylinders 4 so that the raw materials inside the four dispensing cylinders 4 can be mixed evenly.

[0045] Reverse control drive component 7, enabling the following Figure 4 In a clockwise direction, the materials in the base liquid distribution cylinder 4, high-level tank 1, high-level tank 2, and high-level tank 3 are sequentially introduced into the interior of the reaction tank; at the same time, the second motor 20 is started, causing the stirring blade 17 to stir the raw materials inside the reaction vessel; by controlling the temperature inside the condensation chamber 1031 in real time, the copolymerization reaction in the reaction chamber 1032 is completed, generating a liquid; the generated liquid is then filtered through two layers of stainless steel filter screen and degreased cotton before being weighed and packaged.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
