Description

Technical Field

[0001] The invention relates to the field of water reducing agent preparation, and more specifically to a solid-liquid mixing system for preparing water reducing agent. Background Art

[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most water reducers are anionic surfactants, such as lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it has a dispersing effect on cement particles, which can improve its workability, reduce unit water consumption, improve the fluidity of the concrete mixture, or reduce unit cement consumption and save cement.

[0003] The preparation of water reducer is a complex technology, involving multiple steps such as chemical reaction, synthesis and polymerization of surfactants. Generally speaking, the preparation of water reducer is divided into six stages: raw material preparation, sulfonation reaction, neutralization reaction, condensation reaction, surfactant addition and post-treatment. In the stage of surfactant addition, since it is necessary to achieve excellent dispersibility and lubricity of the water reducer, it is necessary to add surfactant to the water reducer solution at the end of the polymerization reaction of the water reducer preparation to give the water reducer excellent dispersibility and lubricity. Since gas will be generated in the polymerization reaction, and because the surfactant will reduce the surface tension of the liquid, the viscosity of the water reducer will increase at the end of the polymerization reaction. At this time, the gas in the polymerization reaction cannot leave the water reducer through the water reducer solution, which will cause a large number of bubbles to form inside the water reducer and on the outer surface of the water reducer, resulting in the water reducer being produced and melted in the concrete. The concrete has defects such as insufficient density, bumpy surface after paving, uneven distribution, and substandard quality. Summary of the invention

[0033] A telescopic cavity 43 is provided at the bottom of the scraper 4, and the bubble-making assembly 5 includes a needle group 51 slidably arranged in the telescopic cavity 43, a connecting plate 52 is fixedly installed on the top of the needle group 51, and guide rods 46 are slidably penetrated at both ends of the connecting plate 52. Two groups of guide rods 46 are fixedly installed on the inner wall at the top of the telescopic cavity 43, and an outer toothed ring 59 is fixedly sleeved on the outer surface of the reciprocating threaded rod 63. A tooth block 58 is movably provided inside the transmission cavity 44, and the tooth block 58 is used in conjunction with the outer toothed ring 59. A push rod 56 fixedly connected to the tooth block 58 is slidably provided inside the transmission cavity 44, and a slide groove 45 used in conjunction with the tooth block 58 is provided on the inner wall of the transmission cavity 44. The tooth block 58 can be moved through The slide groove 45 slides due to the limiting effect, and a return spring 57 is arranged between the push rod 56 and the inner wall of the transmission chamber 44, and one end of the return spring 57 is fixedly connected to the inner wall of the transmission chamber 44, and the other end of the return spring 57 is fixedly connected to the outer surface of the push rod 56, and the end of the push rod 56 away from the return spring 57 is fixedly connected to the second bellows 55, and the end of the second bellows 55 away from the push rod 56 is fixedly inserted with an air guide pipe 54, which passes through the transmission chamber 44 and extends to the telescopic chamber 43. The first bellows 53 is fixedly installed on the top of the inner wall of the telescopic chamber 43, and the air guide pipe 54 is communicated with the first bellows 53, and the bottom of the first bellows 53 is fixedly installed with the connecting plate 52.

[0034] The outer gear ring 59 is a circular ring with a semicircular gear plate fixedly mounted on the outer surface, and the inner gear ring 61 is a circle of gear rows fixed on the inner wall of the ring cavity 14. The inner diameter of the ring cavity 14 is much larger than the diameter of the gear 62, and the gear row part of the gear 62 is located outside the rotating groove 41 when rotating.

[0035] Before the polymerization reaction of the water reducer preparation begins, firstly, the water reducer mixture that has undergone condensation reaction is injected into the stirring chamber 13 through the feed pipe 11 using an external feed pipe, and at the same time, the surfactant is injected into the stirring chamber 13 through the liquid inlet pipe 12 using an external liquid feed pipe, and then the drive motor 2 is started to rotate the stirring rod 3, so as to stir and mix the water reducer mixture and the surfactant, and start the polymerization reaction of the water reducer. When the stirrer body 1 is working, the stirring rod 3 is rotated by the drive motor 2, and the stirring rod 3 will rotate with the scraper 4 at this time, and the scraper 4 will make the power component 6 start to work. When the power component 6 works, it will make the vibration component 7 move, and at the same time, the needle group 51 will reciprocate up and down. While the stirring rod 3 stirs the polymerization reaction mixture, the needle group 51 punctures the bubbles inside the polymerization reaction mixture, thereby reducing the amount of bubbles inside the polymerization reaction, thereby improving the production quality of the water reducer during the polymerization reaction. After being added to the concrete, it has a good effect in improving the density of the concrete, reducing the porosity, and enhancing the strength and durability of the concrete.

[0036] When the power assembly 6 is working, the stirring rod 3 will rotate with the scraper 4. Since the gear 62 in the rotating groove 41 is meshed with the inner gear ring 61 in the ring cavity 14, the gear 62 will continue to rotate when the stirring rod 3 rotates. When the gear 62 rotates, it will drive the reciprocating threaded rod 63 to rotate at a high speed, thereby causing the outer gear ring 59 to rotate at a high speed. Figure 8 As shown in the figure, the outer gear ring 59 rotates clockwise, and the part of the outer gear ring 59 containing a half circle of gear plate pushes the gear block 58 to move rightward. At this time, the return spring 57 is extended and in a stretched state, and the gear block 58 moves rightward to push the second bellows 55 and make the second bellows 55 contract. The gas inside the second bellows 55 will be pushed into the first bellows 53 through the air guide tube 54. The first bellows 53 will extend when the gas enters, thereby pushing the entire connecting plate 52 and the needle group 51 to move downward, thereby achieving the effect of puncturing the bubbles in the water reducer mixture;

[0037] When the other half of the outer gear ring 59 without the tooth plate rotates to the tooth block 58, since the tooth block 58 is no longer limited by the tooth plate on the outer gear ring 59, the spring in the stretched state will shrink immediately and pull the push rod 56 as shown in FIG. Figure 8 53 moves to the left as shown in the figure, thereby extending the second bellows 55, and then sucking the gas in the first bellows 53 into the second bellows 55 through the air guide tube 54, thereby contracting the first bellows 53, and the first bellows 53 will pull the connecting plate 52 and the needle group 51 to move upward together, and in this reciprocating manner, the needle group 51 can repeatedly pierce the bubbles in the water-reducing agent mixture, and can pierce the bubbles generated in the water-reducing agent mixture during the stirring process, thereby reducing the bubbles in the water-reducing agent mixture.

[0038] It should be particularly noted here that the driving motor 2 is a low-speed motor, and the length and telescopic length of the needle group 51 can be adjusted according to actual use.

[0039] like Figure 2 and Figure 3 As shown, the outermost end of the scraper 4 is always in contact with the inner wall of the stirring chamber 13.

[0040] Since the water-reducing agent mixture is in a state of high viscosity during the polymerization reaction, the water-reducing agent mixture will remain on the inner wall of the stirring chamber 13 during the stirring process. During the stirring process, the rotation of the stirring rod 3 will cause the entire scraper 4 to rotate. Since the outermost end of the scraper 4 is always in contact with the inner wall of the stirring chamber 13, the scraper 4 will scrape off the sticky water-reducing agent mixture on the inner wall of the stirring chamber 13, thereby reducing the loss of the water-reducing agent during stirring, thereby saving costs.

[0041] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig. 9 As shown, a long plate 8 parallel to the connecting plate 52 is fixedly mounted on the needle assembly 51 . The long plate 8 is located below the connecting plate 52 , and the long plate 8 is located outside the telescopic cavity 43 .

[0042] When the bubble piercing component 5 starts to work and moves the entire needle group 51 up and down repeatedly, the needle group 51 will be inserted into the water reducer mixture during the downward movement, and the long plate 8 on the needle group 51 will hit the surface of the water reducer. Since the needle group 51 pierces the bubbles inside the water reducer, the water reducer will be gradually compacted as the long plate 8 hits, and the space at the original bubble position will be tightened to reduce the occurrence of voids at that location, further improving the effect of removing bubbles by the piercing component, thereby further improving the production quality of the water reducer during the polymerization reaction.

[0043] like Figure 2 and Figure 3 As shown, the stirring rod 3 is provided with a reciprocating thread groove at the bottom of the scraper 4, and a pressing plate 9 is rotatably sleeved on the outer surface of the stirring rod 3. The pressing plate 9 is used in conjunction with the reciprocating thread groove. The pressing plate 9 and the inner wall of the stirring chamber 13 are squeezed, and the friction force is greater than the friction force between the reciprocating thread groove, and the length of the reciprocating thread groove is less than the length of the needle group 51.

[0044] When the driving motor 2 rotates with the stirring rod 3, due to the extrusion between the pressing plate 9 and the inner wall of the stirring chamber 13, the friction force is greater than the friction between the pressing plate 9 and the reciprocating thread groove. At this time, under the action of the reciprocating thread groove, the pressing plate 9 will rotate along the direction of the reciprocating thread groove and move downward and then upward. During the rotation of the pressing plate 9, the bubbles on the surface of the water-reducing agent mixture will be squeezed and broken. At the same time, during the downward movement of the pressing plate 9, it will work together with the long plate 8 to press down the water-reducing agent mixture and compress the water-reducing agent mixture, thereby further improving the production quality of the water-reducing agent during the polymerization reaction.

[0045] It should be particularly noted here that the pressing plate 9 is made of rubber, and the needle assembly 51 can be normally inserted through the pressing plate 9 .

[0046] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a vibration component 7 is provided inside the vibration cavity 42, and the vibration component 7 is used in conjunction with the reciprocating threaded rod 63. The vibration component 7 includes a sleeve plate 71 sleeved on the outer surface of the reciprocating threaded rod 63, and the gear 62 is threadedly transmitted with the sleeve plate 71 through the reciprocating threaded rod 63. Inner top plates 72 are fixedly installed on the inner walls at both ends of the sleeve plate 71, and multiple groups of impact rings 73 are fixedly installed on the inner wall of the vibration cavity 42. Multiple groups of telescopic rods 74 are fixedly installed on the inner wall of each group of vibration cavities 42. Multiple groups of vibration springs 75 are also fixedly installed on the inner wall of the vibration cavity 42. The outer ends of the vibration springs 75 are fixedly connected to the inner wall of the sleeve 76, and the telescopic ends of the telescopic rods 74 are fixedly connected to the inner wall of the sleeve 76. The inner top plate 72 is used in conjunction with the outer top plate 77, and the space between the outer top plate 77 and the sleeve plate 71 is a reserved groove 78.

[0047] There are multiple groups of outer top plates 77, and the outer top plates 77 are arranged and distributed in the vibration cavity 42 from top to bottom, and each group of adjacent outer top plates 77 are in contact with each other.

[0048] Each group of vibration springs 75 is sleeved in a one-to-one correspondence inside the impact ring 73 , and a telescopic rod 74 is sleeved in a one-to-one correspondence inside each group of vibration springs 75 , and a sleeve 76 is movably sleeved on the outer surface of the impact ring 73 .

[0049] One end of the inner top plate 72 close to the outer top plate 77 is designed to be sharp, and the upper and lower ends of the outer top plate 77 are both rounded. The thickness of the reserved groove 78 when the inner top plate 72 does not contact the outer top plate 77 is the same as the thickness of the outer top plate 77.

[0050] When the stirring rod 3 rotates with the scraper 4, so that the gear 62 inside the scraper 4 rotates with the reciprocating threaded rod 63, the sleeve plate 71 will move downward along the surface of the reciprocating threaded rod 63 with the reciprocating threaded rod 63 as the path, and then move upward. In this process, the sleeve plate 71 moves downward, and the sharp end of the inner top plate 72 will first contact the part with the rounded corner on the upper edge of the outer top plate 77, pushing the outer top plate 77 to move into the reserved groove 78, thereby gradually reducing the internal space of the reserved groove 78. While the outer top plate 77 moves toward the reserved groove 78, the outer top plate 77 will bring the sleeve 76 together as shown in the figure. Figure 6 As shown in the figure, the telescopic rod 74 is extended, and the vibration spring 75 is in a stretched state until the sharp end of the inner top plate 72 contacts the rounded portion of the upper edge of the outer top plate 77. As the inner top plate 72 moves downward, the outer top plate 77 will Figure 6As shown in the figure, it moves to the right. At this time, the space in the reserved groove 78 gradually becomes larger. Under the action of the tensioned vibration spring 75, the telescopic rod 74 will shrink, and the sleeve 76 will start to move to the right to contact the impact ring 73. Since the drive motor 2 adopts a low-speed motor, the inner diameter of the ring cavity 14 is much larger than the diameter of the gear 62. The entire reciprocating threaded rod 63 will rotate at a very fast speed relative to the rotation speed of the stirring rod 3, so that the sleeve 71 quickly moves up and down along the surface of the reciprocating threaded rod 63, and then the sleeve 76 is as shown in the figure. Figure 6 As shown in the figure, when it moves to the right, it will quickly hit the impact ring 73, and the vibration of this part will be transmitted to the outer surface of the scraper 4 through the vibration chamber 42, thereby vibrating the water reducer mixture sticking to the outer surface of the scraper 4, further reducing the loss caused by the stirring of the water reducer and saving costs.

[0051] Usage method: before the polymerization reaction of the water reducer preparation starts, first use the external feed pipeline to inject the water reducer mixture that has undergone condensation reaction into the stirring chamber 13 through the feed pipe 11, and at the same time use the external liquid delivery pipeline to inject the surfactant into the stirring chamber 13 through the liquid inlet pipe 12, and then start the drive motor 2 to rotate the stirring rod 3, so as to stir and mix the water reducer mixture and the surfactant, and start the polymerization reaction of the water reducer. When the stirrer body 1 is working, since the drive motor 2 rotates the stirring rod 3, the stirring rod 3 will rotate with the scraper 4 at this time, and the scraper 4 will make the power component 6 start working. When the power component 6 works, it will make the vibration component 7 move, and at the same time the needle group 51 will reciprocate up and down. While the stirring rod 3 stirs the polymerization reaction mixture, the needle group 51 punctures the bubbles inside the polymerization reaction mixture, thereby reducing the amount of internal bubbles during the polymerization reaction, thereby improving the production quality of the water reducer during the polymerization reaction. After being added to the concrete, it has a good effect in improving the density of the concrete, reducing the porosity, and enhancing the strength and durability of the concrete.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
