Description

Technical Field

[0001] This invention belongs to the field of water-reducing agent formulation technology, specifically a modular formulation device for water-reducing agent components. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining the slump of concrete. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixtures, they disperse cement particles, improve workability, reduce unit water consumption, improve the fluidity of concrete mixtures, reduce unit cement consumption, and save cement. The production process of water-reducing agents requires the mixing of various liquid production agents.

[0003] When preparing water-reducing agents, the solvent, main agent, and additives are usually added to the reactor through multiple feeding pipes. However, the existing method of adding the additives makes it difficult to control the proportions of different components of the water-reducing agent and to adjust the proportions of different components according to the actual conditions of the cement slurry. Furthermore, the pH value of the water-reducing agent needs to be tested during preparation to adjust the addition of different components. Current technologies mostly use sampling tubes to sample the prepared water-reducing agent. However, after sampling, some components may remain inside the sampling tube, which will affect the accuracy of pH value testing when sampling new water-reducing agents.

[0004] Therefore, the present invention provides a modular formulation device for water-reducing agent components. Summary of the Invention

[0009] Preferably, the drive assembly includes a second bevel gear, which is fixedly mounted on the top of the second rotating shaft. The first bevel gear is fixedly connected to the outer wall of the first rotating shaft, and the first bevel gear meshes with the second bevel gear.

[0010] Preferably, two supports are symmetrically fixedly connected to the inner wall of the tank, and a pipe is fixedly connected to one side of the two supports. One end of the pipe extends to the top of the weighing hopper, and an extraction component is provided on the outer wall of the pipe.

[0011] Preferably, the extraction component includes a sleeve, which is fixedly installed on the outer wall of the pipe. A piston plate is slidably connected to the inner wall of the sleeve. A piston rod is fixedly connected to one side of the piston plate. One end of the piston rod passes through the sleeve and is rotatably connected to a connecting shaft.

[0017] 2. In this invention, after the weighing hopper moves downward to discharge the solvent, main agent, and auxiliary agent inside, the cam and the cam work together to make the weighing hopper vibrate continuously downward, which facilitates the shaking off of viscous liquid adhering to the weighing hopper. This avoids the phenomenon of residue sticking to the wall of the weighing hopper, which would lead to the lack of water-reducing agent ingredients and affect the composition of the water-reducing agent.

Furthermore, the continuous downward vibration of the weighing hopper facilitates better discharge of the liquid flushing the weighing hopper. The mixed liquid discharged from the end of the pipe enters the cavity and exits from different outlet pipes, allowing for rinsing at different locations within the symmetrical weighing hopper and improving the rinsing effect.

[0019] 4. In this invention, the rotating plate is controlled by a second motor to move outside the tank, thereby moving the sampling rod outside the tank to sample and test the prepared water-reducing agent. If the pH value does not meet the standard, the required additives are added to the tank for re-mixing. When sampling the water-reducing agent in the tank again, the piston head is controlled by a second hydraulic cylinder to move up and down repeatedly. Through multiple liquid flows, the residual liquid in the sampling chamber is easily cleaned, preventing the residual liquid from affecting the next test of the water-reducing agent.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 11As shown, the present invention provides a technical solution: a modular mixing device for water-reducing agent components, comprising a tank 1, a plurality of feed pipes 2 fixedly connected to the top of the tank 1, a liquid sampling valve 44 fixedly connected to the outer wall of the tank 1, support legs 43 fixedly connected to the bottom of the tank 1, a fixing plate 3 fixedly connected to the inner wall of the tank 1, a weighing assembly disposed above the fixing plate 3, a second rotating shaft 18 rotatably connected to the inner wall of the fixing plate 3, a U-shaped frame 19 fixedly connected to the bottom of the second rotating shaft 18, a third rotating shaft 20 fixedly connected to the bottom of the U-shaped frame 19, a stirring blade 45 fixedly connected to the outer wall of the third rotating shaft 20, a driving assembly disposed at the top of the second rotating shaft 18, and a slot 33 formed on the outer wall of the tank 1, with a sampling assembly disposed inside the slot 33; the weighing assembly includes two first hydraulic cylinders 4. Two first hydraulic cylinders 4 are symmetrically fixedly installed on the top of the fixed plate 3. The output ends of the two first hydraulic cylinders 4 are fixedly connected to the support plate 5. Two sliding shafts 7 are symmetrically fixedly connected to the top of the support plate 5. Limit blocks 9 are fixedly connected to the top of each of the two sliding shafts 7. Mounting plates 6 are slidably connected to the outer walls of the two sliding shafts 7. Springs 8 are sleeved on the outer walls of the two sliding shafts 7. The top of the springs 8 is fixedly connected to the limit blocks 9. The bottom of the springs 8 is fixedly connected to the mounting plate 6. A pressure sensor 10 is fixedly connected to the top of the mounting plate 6. A weighing hopper 11 is fixedly connected to the top of the pressure sensor 10. The weighing hopper 11 is located below the feed pipe 2. Drainage grooves 12 are opened on both sides of the weighing hopper 11. Two baffles 13 are symmetrically fixedly connected to the inner wall of the tank body 1. The baffles 13 fit against the outer wall of the weighing hopper 11.

[0025] Through the above technical solution, the first hydraulic cylinder 4 controls the support plate 5 to move upward, causing the mounting plate 6 to move upward, which in turn moves the weighing hopper 11 upward, moving the drain tank 12 to the baffle 13. The baffle 13 then seals the drain tank 12. Solvents, main agents, and additives required for the water-reducing agent formulation are added to the weighing hopper 11 through several feed pipes 2. The pressure sensor 10 weighs the solvents, main agents, and additives added through the feed pipes 2, accurately controlling the proportions of solvents, main agents, and additives. This allows for adjustment of the amounts of solvents, main agents, and additives according to the required cement slurry application scenario. After adjusting the amounts of solvents, main agents, and additives… After the proportions are determined, the weighing hopper 11 is moved downward by the first hydraulic cylinder 4, causing the drain trough 12 to move below the baffle 13. At this time, the drain trough 12 is in a clear state, allowing the solvent, main agent, and auxiliary agent in the weighing hopper 11 to be discharged. After the solvent, main agent, and auxiliary agent enter the tank 1, the second rotating shaft 18 is rotated by the drive assembly, causing the U-shaped frame 19 to rotate, which in turn drives the third rotating shaft 20 to rotate, causing the stirring blade 45 to rotate and stir the solvent, main agent, and auxiliary agent. The empty trough 33 allows for easy observation of the mixing status of the solvent, main agent, and auxiliary agent in the tank 1, and the liquid taking valve 44 allows for easy removal of the mixed water-reducing agent.

[0026] Specifically, a first motor 14 is fixedly connected to the outer wall of the tank body 1. The output end of the first motor 14 extends into the interior of the tank body 1 and is fixedly connected to a first rotating shaft 15. The first rotating shaft 15 is rotatably connected to the tank body 1. Two cams 16 are symmetrically fixedly connected to the outer wall of the first rotating shaft 15. Two protrusions 17 are symmetrically fixedly connected to the bottom of the mounting plate 6. The bottom of the two protrusions 17 is set as symmetrical slopes.

[0027] Through the above technical solution, after the weighing hopper 11 moves downward, the first motor 14 is started, driving the first rotating shaft 15 to rotate, causing the cam 16 to rotate. When the protruding end of the cam 16 rotates to the protrusion 17, it presses against the inclined surface at the bottom of the protrusion 17. Under the pressure of the cam 16, the protrusion 17 moves upward, driving the mounting plate 6 to move upward, and causing the weighing hopper 11 to move upward. At the same time as the mounting plate 6 moves upward, it presses the spring 8. When the protruding end of the cam 16 rotates to a position away from the protrusion 17, under the action of the spring 8, the mounting plate 6 moves downward quickly and vibrates, driving the weighing hopper 11 to move downward quickly and vibrate. This process is repeated. While the cam 16 rotates, the weighing hopper 11 continues to vibrate downward, which helps to shake off the viscous liquid adhering to the weighing hopper 11, avoiding the phenomenon of hanging on the wall of the weighing hopper 11, which would lead to the lack of water-reducing agent ingredients and affect the composition of the water-reducing agent.

[0028] Specifically, the drive assembly includes a second bevel gear 22, which is fixedly mounted on the top of the second rotating shaft 18. A first bevel gear 21 is fixedly connected to the outer wall of the first rotating shaft 15, and the first bevel gear 21 meshes with the second bevel gear 22.

[0029] Through the above technical solution, the first rotating shaft 15 rotates while driving the first bevel gear 21 to rotate, causing the second bevel gear 22 to rotate, and driving the second rotating shaft 18 to rotate.

[0030] Specifically, two supports 23 are symmetrically fixedly connected to the inner wall of the tank 1. A pipe 24 is fixedly connected to one side of the two supports 23. One end of the pipe 24 extends to the top of the weighing hopper 11. An extraction component is provided on the outer wall of the pipe 24. The extraction component includes a sleeve 25, which is fixedly installed on the outer wall of the pipe 24. A piston plate 26 is slidably connected to the inner wall of the sleeve 25. A piston rod 27 is fixedly connected to one side of the piston plate 26. One end of the piston rod 27 passes through the sleeve 25 and is rotatably connected to a connecting shaft 28. The connecting shaft 28 is rotatably connected to a U-shaped frame 19. Two one-way valves 29 are symmetrically fixedly connected to the inner wall of the pipe 24 with the sleeve 25 as the center. Both one-way valves 29 open from bottom to top.

[0031] Through the above technical solution, when the long end of the U-shaped frame 19 rotates to the right, the connecting shaft 28 pulls the piston rod 27 to the right, causing the piston plate 26 to move to the right. When the long end of the U-shaped frame 19 rotates to the left, the connecting shaft 28 pushes the piston rod 27 to the left, causing the piston plate 26 to move to the left. This process repeats, causing the piston plate 26 to move back and forth as the U-shaped frame 19 rotates. When the piston plate 26 moves to the right, the pulling action of the piston plate 26, in conjunction with the two one-way valves 29, draws the mixed liquid in the tank 1 along the pipe 24 to the sleeve. Inside the box 25, when the piston plate 26 moves to the left, the piston plate 26 squeezes the mixture, which, in conjunction with the two one-way valves 29, causes the mixed liquid inside the box 25 to be discharged along the end of the pipe 24. The mixed liquid discharged from the end of the pipe 24 enters the weighing hopper 11, and then is discharged along the drain trough 12 and re-enters the tank 1. This process is repeated, and while stirring the solvent, main agent, and auxiliary agent in the tank 1, the weighing hopper 11 is continuously flushed to clean the viscous liquid adhering to the wall of the weighing hopper 11. In addition, the continuous downward vibration of the weighing hopper 11 further facilitates the discharge of the liquid flushed by the weighing hopper 11.

[0032] Specifically, a fixing bracket 30 is fixedly connected to the outer wall of the pipe 24. A cavity 31 is opened inside the fixing bracket 30. An outlet pipe 32 is fixedly connected to all four sides of the fixing bracket 30. The outlet pipe 32 is installed at an angle.

[0033] Through the above technical solution, the mixed liquid discharged from the end of the pipe 24 enters the cavity 31 and is discharged from different outlet pipes 32, which facilitates rinsing at different positions in the symmetrical measuring hopper 11 and improves the rinsing effect.

[0034] Specifically, the bottom of the inner wall of the weighing hopper 11 is designed as a symmetrical slope.

[0035] The above technical solution sets the bottom of the weighing hopper 11 as an inclined surface, which facilitates better discharge of the internal liquid.

[0036] Specifically, the sampling assembly includes a second motor 34, which is fixedly installed at the bottom of the empty trough 33. A rotating plate 35 is fixedly connected to the output end of the second motor 34. A mounting bracket 36 is rotatably connected to the bottom of the rotating plate 35. A sampling rod 37 is rotatably connected to the inner wall of the mounting bracket 36. A sampling cavity 38 is opened inside the sampling rod 37. The bottom of the sampling cavity 38 is set as an annular inclined surface. An inlet 39 is opened at the bottom of the sampling rod 37. The inlet 39 communicates with the sampling cavity 38. A second hydraulic cylinder 40 is fixedly connected to the top of the inner wall of the sampling cavity 38. A piston head 41 is fixedly connected to the output end of the second hydraulic cylinder 40. The piston head 41 is slidably connected to the sampling cavity 38. A counterweight ring 42 is fixedly connected to the outer wall of the sampling rod 37. The top and bottom of the counterweight ring 42 are both set as annular inclined surfaces.

[0037] Through the above technical solution, after the solvent, main agent, and auxiliary agent in tank 1 are stirred, the piston head 41 is moved upward by the second hydraulic cylinder 40 to extract the prepared water-reducing agent, so that the water-reducing agent enters the sampling chamber 38 through the inlet 39. The second motor 34 is started, driving the rotating plate 35 to rotate to the outside of tank 1. Under the pull of the rotating plate 35, the sampling rod 37 rotates to the outside of tank 1. After the sampling rod 37 rotates, the counterweight ring 42 makes it easy for the inlet 39 to remain downward, and the piston head 41 is moved downward by the second hydraulic cylinder 40. The water-reducing agent in the sampling chamber 38 is squeezed out along the liquid inlet 39, which facilitates the sampling and pH value testing of the water-reducing agent in the tank 1. If the pH value does not meet the standard, the required additives need to be added to the tank 1 and re-mixed. When sampling the water-reducing agent in the tank 1 again, the sampling rod 37 is controlled by the second motor 34 to re-enter the tank 1, and the piston head 41 is controlled by the second hydraulic cylinder 40 to move up and down repeatedly. After multiple liquid flows, the residual liquid in the sampling chamber 38 is easily cleaned to prevent the residual liquid from affecting the next test of the water-reducing agent.

[0038] Working principle: In use, the first hydraulic cylinder 4 controls the support plate 5 to move upward, causing the mounting plate 6 to move upward, which in turn moves the weighing hopper 11 upward, moving the drain trough 12 to the baffle 13. The baffle 13 then seals the drain trough 12. Solvents, main agents, and additives required for the water-reducing agent formulation are added to the weighing hopper 11 through several feed pipes 2. The pressure sensor 10 weighs the solvents, main agents, and additives added through the feed pipes 2, accurately controlling the proportions of the solvents, main agents, and additives. This allows for adjustment of the amounts of solvents, main agents, and additives according to the required cement slurry application scenario. After adjusting the proportions of the solvents, main agents, and additives, the first hydraulic cylinder 4 controls the weighing hopper 11 to move downward, causing the drain trough 12 to move below the baffle 13. At this point, the drain trough 12 is positioned... The unobstructed flow allows for the discharge of solvents, main agents, and additives from the symmetrical measuring hopper 11. After the solvents, main agents, and additives enter the tank 1, the first motor 14 is started, driving the first rotating shaft 15 to rotate. The rotation of the first rotating shaft 15 drives the first bevel gear 21 to rotate, causing the second bevel gear 22 to rotate, which in turn drives the second rotating shaft 18 to rotate, causing the U-shaped frame 19 to rotate, which in turn drives the third rotating shaft 20 to rotate, causing the stirring blades 45 to rotate, thus stirring the solvents, main agents, and additives. The empty trough 33 facilitates observation of the mixing status of the solvents, main agents, and additives in the tank 1. Simultaneously, the rotation of the first rotating shaft 15 causes the cam 16 to rotate. When the protruding end of the cam 16 rotates to the protrusion 17, it presses against the inclined surface at the bottom of the protrusion 17. Under the pressure of the cam 16, the protrusion 17 moves upward. The mounting plate 6 moves upward, causing the weighing hopper 11 to move upward. Simultaneously, the mounting plate 6 presses against the spring 8. When the protruding end of the cam 16 rotates away from the protrusion 17, the spring 8 causes the mounting plate 6 to move rapidly downward and vibrate, causing the weighing hopper 11 to move rapidly downward and vibrate. This process repeats, causing the weighing hopper 11 to continuously vibrate downward as the cam 16 rotates, effectively shaking off viscous liquid adhering to the weighing hopper 11 and preventing residue buildup that could lead to insufficient water-reducing agent preparation and affect the agent's composition. As the U-shaped frame 19 rotates, when the long end of the U-shaped frame 19 rotates to the right, the connecting shaft 28 pulls the piston rod 27 to the right, causing the piston plate 26 to move to the right. When the long end of 19 rotates to the left, it pushes the piston rod 27 to the left through the connecting shaft 28, causing the piston plate 26 to move to the left. This process repeats as the U-shaped frame 19 rotates, causing the piston plate 26 to move back and forth. When the piston plate 26 moves to the right, the pulling action of the piston plate 26, in conjunction with the two one-way valves 29, draws the mixed liquid in the tank 1 along the pipe 24 into the casing 25. When the piston plate 26 moves to the left, the squeezing action of the piston plate 26, in conjunction with the two one-way valves 29, causes the mixed liquid in the casing 25 to be discharged along the end of the pipe 24. The mixed liquid discharged from the end of the pipe 24 enters the cavity 31 and is discharged from different outlet pipes 32, facilitating rinsing at different positions in the symmetrical measuring hopper 11 and improving the rinsing effect.The mixed liquid entering the weighing hopper 11 is discharged along the drain trough 12 and re-enters the tank 1. This process is repeated to stir the solvent, main agent, and auxiliary agent in the tank 1, continuously rinsing the weighing hopper 11 and facilitating the removal of viscous liquid adhering to its walls. The downward vibration of the weighing hopper 11 further facilitates the discharge of the rinsed liquid. The inclined bottom of the weighing hopper 11 further aids in the drainage of the internal liquid. After stirring the solvent, main agent, and auxiliary agent in the tank 1, the piston head 41 is moved upward by the second hydraulic cylinder 40 to extract the prepared water-reducing agent. The water-reducing agent enters the sampling chamber 38 through the inlet 39. The second motor 34 is activated, causing the rotating plate 35 to rotate outside the tank 1. Under the pull of the rotating plate 35, the sampling rod... The sampling rod 37 rotates to the outside of the tank 1. After rotation, the counterweight ring 42 ensures that the inlet 39 remains downward. The second hydraulic cylinder 40 controls the piston head 41 to move downward, squeezing out the water-reducing agent in the sampling chamber 38 along the inlet 39. This facilitates sampling and pH value testing of the water-reducing agent in the tank 1. If the pH value does not meet the standard, the required additives are added to the tank 1 for re-mixing. When sampling the water-reducing agent in the tank 1 again, the second motor 34 controls the sampling rod 37 to re-enter the tank 1. The second hydraulic cylinder 40 controls the piston head 41 to move up and down repeatedly. Through multiple liquid flows, residual liquid in the sampling chamber 38 is cleaned to prevent residual liquid from affecting the next test of the water-reducing agent. The prepared water-reducing agent is easily removed through the sampling valve 44.
