Description

Technical Field

[0001] The invention relates to the technical field of building material preparation, and in particular to production and processing equipment and a process for a redispersible alkali-free powdered quick-setting agent. Background Art

[0002] Accelerator plays a key role in concrete construction. It can significantly shorten the setting time of concrete and improve construction efficiency. At present, the production and processing of accelerator usually involves multiple links, among which the reactor plays a core role in the whole production process. However, the existing accelerator production and processing equipment has serious deficiencies in the use of reactors.

[0003] First, the mixing is uneven. The uniformity of mixing of materials of different components in the reactor is directly related to the quality of the accelerator. However, in the mixing process of current reactors, there is often insufficient local mixing. This is because the stirring equipment of the agitator is not designed reasonably and cannot cover the entire internal space of the reactor, resulting in insufficient contact and fusion between different components.

[0004] Secondly, the emulsification is not thorough. The emulsification effect is to disperse one liquid into a second immiscible liquid. The emulsifying disperser emulsifies, mixes and disperses the materials to make the fineness distribution of the materials uniform. Through the strong high-speed shearing function, the product can meet the emulsification and dispersion requirements in a short time. However, the existing reactor cannot achieve efficient emulsification due to the single stirring method and insufficient stirring intensity. This makes it impossible for different materials to be evenly dispersed in the emulsion, affecting the processing quality of the accelerator.

[0005] In view of the above problems, there is an urgent need for a new type of accelerator production and processing equipment that can achieve more thorough emulsification, mixing and dispersion in the reactor. Summary of the invention

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0052] like Figure 1-6 As shown, a production and processing equipment for a redispersible alkali-free powdered quick-setting agent comprises a first base 1, a second base 4, a reaction kettle 16, a stirring mechanism 2 and a crushing mechanism 8. The first base 1 is provided with a reaction kettle 16, a lifting mechanism 7 and a stirring mechanism 2 on the upper part. The stirring mechanism 2 is provided on the lifting mechanism 7 and can be lifted and lowered under the drive of the lifting mechanism 7; the lifting mechanism 7 is connected to the first base 1 through a moving component 6 and can be moved horizontally under the drive of the moving component 6; the stirring mechanism 2 comprises a first connecting platform 201, a first feeding port 202, a first driving motor 203, a first driving The first connecting platform 201 is a cylindrical hollow structure with an opening at the bottom, and a plurality of first feed ports 202 are arranged on the first connecting platform 201. The first driving motor 203 is arranged on the upper part of the first connecting platform 201, and the output shaft of the first driving motor 203 is connected to the first driving shaft 204 through a coupling, and a plurality of disturbance frames 205 are arranged on the first driving shaft 204; the interior of the first base 1 is connected to the crushing mechanism 8 on the second base 4 through the first feeding bracket, which is used to transport the quick-setting agent discharged from the crystallizer at the bottom of the reactor 16 and crush it.

[0053] It should be noted that when producing the accelerator, dispersion and emulsification fusion is an important step. First, different materials need to be added in batches and then stirred. Among them, the stirring function of the existing reactor 16 is relatively single, and stirring can only be performed in the middle part of the reactor 16. The two sides cannot be fully reached, resulting in uneven fusion of materials on both sides. Based on this, we designed a processing equipment that can enhance emulsification, mixing and dispersion, thereby improving the mixing effect on both sides of the reactor 16.

[0054] It should be further explained that a reactor 16 and a stirring mechanism 2 are arranged on the upper part of the first base 1, wherein the stirring mechanism 2 is connected to the track 17 on the first base 1 through a lifting mechanism 7 and a moving assembly 6, and the stirring mechanism 2 is moved laterally through the moving assembly 6 to facilitate the alternating use of different stirring equipment, and is lifted and lowered by the lifting mechanism 7 to control the upper and lower spacing of the disturbance frame 205 in the reactor 16, thereby improving the uniformity during stirring, and can realize automatic control, which is convenient for the operator to adjust and use.

[0055] It should be further explained that a plurality of first feed ports 202 and first drive motors 203 are arranged on the upper part of the first connecting platform 201. A flexible feed pipe is arranged on the upper part of the first feed port 202 to facilitate the introduction and addition of different materials. Moreover, the flexible feed pipe is arranged so that when the entire stirring mechanism 2 is raised and lowered, the pipe itself is bent by its flexibility to avoid interference with other feeding equipment. The first drive motor 203 is connected to the first drive shaft 204, and the first drive shaft 204 is driven to rotate by the first drive motor 203, thereby rotating the disturbance frame 205, thereby realizing the first stirring and fusion of the materials.

[0056] It should be particularly noted that a second base 4 is provided at one end of the first base 1, and a crushing mechanism 8 is provided on the upper part of the second base 4, and automatic feeding is performed through the first feeding bracket, and the crystallized quick-setting agent can be crushed through the crushing mechanism 8.

[0057] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the lifting mechanism 7 includes a column 701, a fixed support 703, a second drive motor 704, a first gear 705, a lifting slide 710, a cross bar 707 and a first connector 709. The lifting slide 710 is slidably connected with the first slide bar 715 on the column 701 through a first slide groove 712 on one side to form a liftable structure; a rack 713 is provided on the lifting slide 710, and the rack 713 is meshed and connected with the first gear 705 on the fixed support 703. The first gear 705 is connected to the second drive motor 704 through a coupling to form a drive structure; one end of the lifting slide 710 is connected to the first connecting platform 201 through the cross bar 707 and the first connector 709; the reverse The reactor 16 is a cylindrical hollow structure with an opening at the top, and the reactor 16 is arranged on the receiving platform 15 of the first base 1. A crystallizer is arranged at the discharge port of the reactor 16, and a transport trough is arranged at the bottom of the crystallizer; a fixed support 703 is arranged on the other side of the column 701, and a fixing ear is arranged on the fixed support 703, and a rotating shaft and a first gear 705 connected to the rotating shaft are arranged in the middle of the two fixing ears, and the first gear 705 is arranged corresponding to the first rectangular opening 702 of the column 701, so as to facilitate the meshing connection between the first gear 705 and the rack 713; an auxiliary guide wheel 711 is arranged on one side of the column 701, and the auxiliary guide wheel 711 is arranged in contact with the guide groove 714 on the side of the column 701.

[0058] It should be noted that after the material inside the reactor 16 is stirred by the stirring mechanism 2, it needs to be emulsified and dispersed again by the double-sided stirring mechanism 3. In this process, we need to use the stirring mechanism 2 and the double-sided stirring mechanism 3 alternately. Therefore, we set two groups of moving components 6 and two groups of lifting mechanisms 7 on the upper part of the first base 1 to achieve replacement. Among them, the lifting slide 710 is slidably connected with the first slide bar 715 on the column 701 through the first slide groove 712 on one side to form a liftable structure, and then the first gear 705 is driven to rotate by the second drive motor 704 on the fixed support 703. The first gear 705 is meshed with the rack 713 on the lifting slide 710, thereby driving the entire lifting slide 710 to rise and fall, and the lifting slide 710 is connected to the stirring mechanism 2 through the cross bar 707 and the first connector 709 to achieve lifting.

[0059] It should be noted that the lifting slide 710 needs to drive the stirring mechanism 2 to lift and lower, and it bears a heavy load. In order to make the lifting process smoother and more stable, we have set auxiliary guide wheels 711 on both sides of the lifting slide 710, and the auxiliary guide wheels 711 extend into the guide groove 714 on the side of the column 701, which can play an auxiliary operation role during lifting.

A first rotating shaft 603 is arranged at the bottom of the sliding base 601, and the first rotating shaft 603 is connected to the track 17 on the first base 1 through the rotating wheel 604. One end of the first rotating shaft 603 is connected to the first sprocket 605 on the third driving motor 602 through the second sprocket 607 and the second chain 606; an auxiliary slide 608 is arranged on one side of the sliding base 601, and the auxiliary slide 608 is movably connected to the second slide on the side of the first base 1 through the second slide groove 609.

[0061] It should be noted that the movable assembly 6 is configured to allow the entire lifting mechanism 7 to move laterally together with the stirring mechanism 2, so that the stirring mechanism 2 and the double-sided stirring mechanism 3 can give way to each other when they are replaced to prevent interference, wherein the sliding base 601 is connected to the track 17 and the second slide bar on the first base 1 respectively through the rotating wheel 604 and the auxiliary slide 608 at the bottom, and a third driving motor 602 is arranged on the upper part of the sliding base 601, and a transmission structure is formed by the second sprocket 607, the second chain 606 and the first sprocket 605 to realize automatic drive.

The rotating bracket 310 is symmetrically provided with a first connecting arm and a second connecting arm. The first connecting arm is provided with a third rotating shaft and a second gear 311. The second gear 311 is provided on the third rotating shaft. The second gear 311 is connected to the inner wall of the second connecting platform 301. The toothed ring 309 on the wall is meshingly arranged, and when the second rotating shaft 308 rotates, the rotating bracket 310 also rotates. At this time, the second gear 311 can drive the third rotating shaft to rotate based on the toothed ring 309, and then the stirring structure 9 on the other end of the third rotating shaft also rotates, thereby completing the emulsification and dispersion of the material during the rotation of the rotating bracket 310. In summary, the fifth drive motor 307 drives the second rotating shaft 308 to rotate, and then drives the rotating bracket 310 to rotate. With the assistance of the toothed ring 309, the third rotating shaft and the stirring structure 9 can be driven to rotate, and the stirring structure 9 is used to complete the stirring, emulsification and dispersion of the material at the inner wall of the reactor 16, thereby enhancing the fusion efficiency of the material.

[0065] It should be further explained that, in order to improve the efficiency of emulsification, an immersion tube 314 is arranged on the second connecting arm 313. An ultrasonic probe is arranged at one end of the immersion tube 314 for emitting ultrasonic waves. When ultrasonic waves propagate in the liquid, periodic pressure changes will occur. When the pressure drops to a certain level, tiny bubbles will form in the liquid. These bubbles will rapidly expand and contract under the action of ultrasonic waves and eventually burst. When the bubbles burst, strong local high temperature, high pressure and microjets will be generated, which can break the particles in the liquid into smaller sizes and promote mixing between different liquids. The other end of the immersion tube 314 passes through the arc-shaped opening 302 on the second connecting platform 301 and is connected to the sound wave generator 305, and an auxiliary mechanism 14 is arranged at the connection between the immersion tube 314 and the arc-shaped opening 302 for assisting rotation.

[0066] It should be further explained that, in order to improve the cutting and dispersing effect, an agitator 10 and a dispersing cutter 11 are respectively arranged on the connecting terminal 902 of the stirring main shaft 901, wherein the function of the agitator 10 is to stir the solution by rotating the propeller blades 1003 inside the stirring groove 1002 during the rotation of the stirring main shaft 901, thereby making the solution flow and promoting the fusion of the solution, and the function of the dispersing cutter 11 is to generate a stronger shear force on the solution through the multiple cutting holes 1103 inside the cutting groove 1101 during the rotation of the stirring main shaft 901, thereby more effectively crushing and dispersing the particles in the liquid.

[0067] It should be particularly noted that the connecting guide groove 306 is arranged on the second connecting platform 301 , and the fifth driving motor 307 is arranged inside the connecting guide groove 306 , which can play a certain protective role for the fifth driving motor 307 .

[0068] like Figure 10-12 As shown, the auxiliary mechanism 14 includes a third connector 1401, a connecting through hole 1402, a second rectangular opening 1403, a transverse sliding platform 1405, a telescopic rod 1406, a guide support 1408 and a pressure spring 1407. The third connector 1401 is connected to the immersion tube 314 through the upper connecting through hole 1402. The second rectangular opening 1403 is symmetrically arranged on both sides of the third connector 1401. The transverse sliding platform 1405 and the telescopic rod 1406 are arranged inside the second rectangular opening 1403. 406; the transverse sliding platform 1405 is slidably connected to the third sliding groove 1404 on the inner wall of the second rectangular opening 1403 through the third sliding platforms 1410 on both sides, one end of the transverse sliding platform 1405 is connected to the third connector 1401 through the telescopic rod 1406, a pressure spring 1407 is arranged on the outer wall of the telescopic rod 1406 to form an elastic structure, a guide support 1408 is arranged on the other end of the transverse sliding platform 1405, and an auxiliary rotating wheel 1409 is arranged inside the guide support 1408.

[0069] It should be noted that when the immersion tube 314 rotates based on the rotating bracket 310, its pipe will move in the arc-shaped opening 302. When in use, it is found that without auxiliary equipment, the immersion tube 314 will often rub against the edge of the arc-shaped opening 302, resulting in difficulty in moving the immersion tube 314. Based on this, we designed an auxiliary mechanism 14 to assist in operation. The third connector 1401 is sleeved on the immersion tube 314 through the connecting through hole 1402, and two connectors are respectively provided on both sides of the third connector 1401. The second rectangular opening 1403 has a transverse sliding platform 1405 slidingly arranged inside thereof. One end of the transverse sliding platform 1405 is connected to the third connector 1401 body via a telescopic rod 1406, and a pressure spring 1407 is arranged outside the telescopic rod 1406 to form an elastic structure. A guide support 1408 and an auxiliary rotating wheel 1409 are arranged on the other end of the transverse sliding platform 1405. The auxiliary rotating wheel 1409 is arranged at the junction with the inner wall of the arc-shaped opening 302 to assist the operation during the rotation process.

[0070] like Figure 1 , Figure 2 , Figure 3 , Fig.14 , Fig.15 and Fig.16 As shown, the pulverizing mechanism 8 includes a first pulverizing box 801, a second pulverizing box 803, a first transport platform 805, a second transport platform 804 and a loading platform 802. The first pulverizing box 801 and the second pulverizing box 803 are respectively arranged on the upper part of the second base 4, and the first transport platform 805 and the second transport platform 804 are arranged at the bottom of the first pulverizing box 801 and the second pulverizing box 803. The discharge end of the first transport platform 805 is connected to the loading platform 802; two symmetrically arranged pulverizing rollers 813 are arranged inside the first pulverizing box 801, and one end of the pulverizing roller 813 is connected to the driving box 807; a screen 812 is arranged inside the first pulverizing box 801, and the screen The net 812 is located directly below the crushing roller 813; a third gear 808 and a fourth gear 809 connected to the main shafts of the two crushing rollers 813 are arranged inside the driving box 807, and the third gear 808 and the fourth gear 809 are meshed and connected; a sealing cover 810 is arranged at the opening of the driving box 807, and a fourth driving motor 811 is arranged on the sealing cover 810, and the output shaft of the fourth driving motor 811 is connected to the main shaft of the crushing roller 813 through a coupling; a feeding belt is arranged inside the loading platform 802, and a plurality of lifting plates are arranged on the feeding belt, and the discharge end of the loading platform 802 is connected to the second feeding port 806 of the second crushing box 803.

[0071] It should be noted that the crushing mechanism 8 is provided to crush the flocculant in block form after crystallization, wherein a first crushing box 801 and a second crushing box 803 are provided on the upper part of the second base 4. After the first crushing box 801 crushes the flocculant for the first time, it is transported through the first transport platform 805 at the bottom, and then the crushed flocculant is introduced into the second crushing box 803 through the loading platform 802 for secondary crushing, and then transferred through the second transport platform 804, and the packaging process is completed through the packaging equipment.

[0072] It should be further explained that the first crushing box 801 and the second crushing box 803 both adopt the same structural design, and are both provided with two crushing rollers 813 inside, which complete the crushing process of the flocculant under the drive of the driving box 807. The difference between the two is that the mesh number of the screen 812 inside the second crushing box 803 is smaller than the mesh number of the screen of the first crushing box 801, so that the crushing can be more delicate.

[0073] like Figure 1 , Figure 2 , Figure 3 , Fig.14 , Fig.15 and Fig.16 As shown, the dust removal mechanism 5 is also included, and the dust removal mechanism 5 includes a first carrier plate 502, a second carrier plate 505, a third carrier plate 506, a first air duct, a second air duct 507 and a purification box 510. The first carrier plate 502 is arranged on the upper part of the first base 1 through a first connecting pillar 501, the second carrier plate 505 is arranged on the second base 4 through a second connecting pillar 511, and the third carrier plate 506 is arranged on the second base 4 through a third connecting pillar 512. The second carrier plate 505 and the third carrier plate 506 are respectively located on the first A second air duct is provided above the crushing box 801 and the second crushing box 803, and on the second carrier plate 505 and the third carrier plate 506 respectively; the upper part of the second air duct is connected to another air duct through a second air guide pump and a second air guide duct 507, and the second air guide duct 507 is connected to the purification box 510 through a third air guide duct; a first air duct 503 is provided on the first carrier plate 502, and the first air duct 503 is connected to the three-way connector 509 on the second air guide duct 507 through a first air guide pump 504 and the first air guide duct.

[0074] It should be noted that dust and odor will be generated in the process of mixing different materials in the reactor 16, and a large amount of dust will also be generated in the two crushing processes of the crushing mechanism 8. If it is not handled in time, it will cause dust to overflow and cause pollution to the working environment. Based on this, we have designed a dust removal mechanism 5, which attracts the odor generated in the reactor 16 through the first air guide hood 503 on the first carrier plate 502, and then introduces it into the second air guide duct 507 through the first guide pump 504, and enters the purification box 510 for purification.

[0075] It should be further explained that the second carrier plate 505 and the third carrier plate 506 are respectively arranged on the upper part of the first crushing box 801 and the second crushing box 803, and the dust generated during crushing is adsorbed in the same way and enters the purification box 510 for unified purification treatment.

[0076] A production process of a redispersible alkali-free powdered accelerating setting agent comprises the following steps:

[0077] S1, adding the fluorosilicic acid solution into the reaction kettle 16 and letting it stand for standby use;

[0078] S2, adding aluminum hydroxide to the reaction kettle 16, and starting the stirring mechanism 2 to stir the two solutions evenly;

[0079] S3, closing the valve of the reactor 16, adding sulfuric acid after reacting for 20 minutes, and continuing the reaction;

[0080] S4, introducing the solution after the reaction in step S3 into a crystallizer for crystallization treatment, and after the crystallization is completed, the solution is discharged and sent to a pulverizing mechanism 8 through a transport trough for two-stage pulverization;

[0081] S5. Pack the crushed quick-setting agent.

[0082] In the step S1, the amount of fluorosilicic acid solution added is 40 parts, and the concentration is 20 mol / L; in the step S2, the amount of aluminum hydroxide added is 30 parts, the stirring speed is 30 rpm, and the stirring time is 25 min; in the step S3, the amount of sulfuric acid added is 35 parts, which can be added in two times, and the reaction time after adding is 43 min; in the step S4, aluminum sulfate can be added during the secondary crushing, and the amount of aluminum sulfate added is 34 parts; in the step S1, fluorosilicic acid can be replaced by hydrofluoric acid.

[0083] Table 1 Fluorosilicic acid addition amount versus coagulation time

[0084]

[0085] Table 1 shows the effect of fluosilicic acid dosage on coagulation time when aluminum hydroxide and sulfuric acid remain unchanged and fluosilicic acid is added as a variable. From Table 1, it can be concluded that as the amount of fluosilicic acid added increases and the concentration increases, the coagulation time becomes faster. When the dosage exceeds 35 parts and the concentration is greater than 20 mol / L, the coagulation speed becomes faster, but the strength after coagulation decreases.

[0086] Based on the comparison of the above data, it can be concluded that the best addition amount of fluorosilicic acid is 30-40 parts and the concentration is 15-25, but the pH value is the lowest and there is stratification.

[0087] Table 2 is a comparison of the use of fluorosilicic acid alone and the use of fluorosilicic acid and hydrofluoric acid at the same time

[0088]

[0089] Table 2 is the data conclusion of using fluorosilicic acid alone and fluorosilicic acid and hydrofluoric acid at the same time, comparing the changes in cement setting time and strength. Through the above data, we can draw the following conclusions:

[0090] When the concentration of hydrofluoric acid is between 20mol / L and 25mol / L and the dosage is between 15 and 25 parts, the coagulation time and strength are most reasonable.

[0091] When fluorosilicic acid and hydrofluoric acid are used at the same time, if the dosage is too high, the cement setting time will be significantly improved, but the early setting strength and late setting strength will decrease.

[0092] When fluorosilicic acid and hydrofluoric acid are used at the same time, it can be seen from the comparison data that when the hydrofluoric acid concentration is 15 mol / L and the dosage is 20 parts, and the fluorosilicic acid concentration is 20 mol / L and the addition amount is 20 parts, the setting time is most reasonable and the later strength retention rate is best.

[0093] Table 3 shows the effect of the change in pH value on the stratification amount of the final product by adjusting the amount of aluminum hydroxide and sulfuric acid with a fixed amount of fluorosilicic acid and hydrochloric acid.

[0094]

[0095] From Table 3 we can conclude that:

[0096] 1. When the amount of aluminum hydroxide added is less than 25 parts or more than 40 parts, it has a significant impact on the performance stratification of the final product;

[0097] 2. When the amount of sulfuric acid added is less than 28 parts, the reaction is not complete, which has a great impact on the secondary coagulation time of the final product, and the aluminum hydroxide that has not reacted completely will precipitate;

[0098] 3. When the amount of sulfuric acid added is higher than 40 parts, the pH value is unqualified, and the national standard requires it to be greater than or equal to 2;

[0099] By comparing the experimental data in Table 1, Table 2 and Table 3, we can conclude that:

[0100] The first optimal formula of the present invention is as follows: 40 parts of fluorosilicic acid, 30 parts of aluminum hydroxide, and 35 parts of sulfuric acid. When the concentration of fluorosilicic acid is 20 mol / L, the coagulation time and the effect after coagulation are optimal.

[0101] The second optimal formula of the present invention is as follows: 30 parts of fluorosilicic acid, 30 parts of aluminum hydroxide, and 35 parts of sulfuric acid. When the concentration of fluorosilicic acid is 15 mol / L, the coagulation time and the effect after coagulation are optimal.

[0102] The production process of the powdered quick-setting agent of the invention adopts an alkali-free production process, which can reduce corrosion to the concrete structure and has good dispersibility, thereby ensuring that the coagulant is evenly distributed in the concrete and improving the performance of the concrete.

[0103] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
