Technical Field
[0001] The present invention relates to the technical field of polycarboxylate superplasticizers, and particularly to a mixing device for processing polycarboxylate superplasticizers and an operation method thereof. Background Art
[0002] Polycarboxylate superplasticizer is a high-performance superplasticizer and a cement dispersant in the application of cement concrete. It is widely used in projects such as highways, bridges, dams, tunnels, and high-rise buildings. Due to its high water reduction rate, good slump retention performance, and fast strength growth, polycarboxylate superplasticizer is suitable for preparing high-strength and ultra-high-strength concrete, high-fluidity and self-compacting concrete, and has become a research and development hotspot for concrete admixtures at home and abroad. When producing polycarboxylate superplasticizer, it is necessary to mix its raw materials, so a mixing device for polycarboxylate superplasticizer raw materials is required for mixing.
[0003] The patent publication number CN219849076U discloses a mixing device for polycarboxylate superplasticizer raw materials. By setting the combined use of a connecting plate, a transmission box, a stirring rod, a connecting rod, a brush, a rotating motor, a unidirectional screw, a moving block, and a connecting block, the advantage of uniformly mixing the polycarboxylate superplasticizer raw materials left and right is achieved, and the problem of the existing mixing device for polycarboxylate superplasticizer raw materials is solved. During mixing, due to the inconvenient change of the position of the stirring rod, there are blind spots in the mixing of the polycarboxylate superplasticizer raw materials, and at the same time, some raw materials will adhere to the inner wall of the device, resulting in uneven mixing of the polycarboxylate superplasticizer raw materials by the device and affecting the production of polycarboxylate superplasticizer. By setting a first opening and a second opening, the first opening enables the connecting block to move with the moving block, giving the connecting block a moving space, and the second opening enables the stirring rod to move when the connecting plate moves, giving the stirring rod a moving space. By setting a limit bearing, the left side of the unidirectional screw can be limited to prevent the unidirectional screw from shaking during rotation. However, the following problems still exist in the actual use of the above patent: Although the mixing device for polycarboxylate superplasticizer raw materials achieves the advantage of uniformly mixing the polycarboxylate superplasticizer raw materials left and right by setting the combined use of a connecting plate, a transmission box, a stirring rod, a connecting rod, a brush, a rotating motor, a unidirectional screw, a moving block, and a connecting block, it is impossible to add small materials during the mixing of polycarboxylate superplasticizer raw materials. By adding small materials (such as silicone, anionic surfactants, etc.), the air content of the polycarboxylate superplasticizer can be reduced, thereby improving the properties of the polycarboxylate superplasticizer. However, the addition amount of small materials is small, and it is impossible to uniformly mix the small materials inside the polycarboxylate superplasticizer, thus affecting the properties of the polycarboxylate superplasticizer.
[0004] Therefore, a mixing device for processing polycarboxylate superplasticizers and an operation method thereof are proposed to solve the problems mentioned above. Summary of the Invention

[0009] Preferably, a rotating bracket is symmetrically installed on one side of the central position at the top of the mixing device.

[0016] By adopting the above technical solution, by setting a one-way valve, under the action of the valve expansion rod and the valve spring, the valve piston is in fitting connection with the valve protrusion, so as to realize the closing of the one-way valve, and thus achieve the effect of quantitatively adding small materials, and at the same time, it will not cause the polycarboxylate superplasticizer to enter the inside of the feeding horizontal pipe and the vertical pipe, thereby affecting the adding effect of the small materials. Since the amount of small materials to be added is small, the small materials and the polycarboxylate superplasticizer can be better mixed by the method of layered addition, thereby reducing the air content of the polycarboxylate superplasticizer and improving the properties of the polycarboxylate superplasticizer.
[0017] Preferably, the small material mixing mechanism includes a mixing cylinder.

[0018] By adopting the above technical solution, the small materials and the aqueous solution are injected into the mixing cylinder by using the feeding pipe and the feeding hopper, and the mixing motor is started to drive the mixing main gear to rotate.

[0020] By adopting the above technical solution, by using the meshing connection characteristics among the mixing main gear, the mixing driven gear and the meshing tooth ring, and while the meshing tooth ring is fixed, not only can the mixing driven gear drive the mixing tripod to revolve, but also the mixing driven gear can rotate self, so that the mixing main gear drives the vertical rotating rod and the mixing auger to rotate. By using the structural characteristics of the mixing auger, the up-and-down stirring of the small materials and the aqueous solution can be realized.
[0021] Preferably, a second mixing bracket is fixedly installed on one side of the vertical rotating rod close to the first mixing bracket. A mixing rotating rod is fixedly installed between the two second mixing brackets. Mixing stirring forks are fixedly installed on the outer side of the mixing rotating rod. A second valve is fixedly installed at the bottom of the mixing cylinder. The second valve is fixedly connected to a pump body. The output end of the pump body is fixedly connected to a connecting pipe. A connector is fixedly installed at the end of the connecting pipe. The connector is fixedly installed on the top of the vertical pipe. A support plate is fixedly installed at the bottom of the mixing cylinder. Support rods are fixedly installed around the bottom of the support plate. The support rods are fixedly installed on the top of the mixing device.
[0022] By adopting the above technical solution, the mixing rotating rod drives the mixing stirring forks to rotate horizontally, thereby improving the mixing effect of the small materials and the aqueous solution. The first mixing bracket drives the cleaning spiral blades to rotate, which can clean the inner wall of the mixing cylinder and avoid wasting small materials. By opening the second valve and using the pump body to generate a certain water pressure, it is convenient to pump the mixture of small materials and aqueous solution into the interior of the mixing device.
[0023] Preferably, Step 1: Use the feed pipe and feed hopper to inject small materials and aqueous solution into the mixing cylinder. Start the mixing motor to drive the mixing main gear to rotate. Utilize the meshing connection characteristics among the mixing main gear, mixing driven gear, and meshing ring. With the meshing ring fixed, not only can the mixing driven gear drive the mixing tripod to revolve, but also the mixing driven gear can rotate on its own axis, enabling the mixing main gear to drive the vertical rotating rod and the mixing auger to rotate. Utilize the structural characteristics of the mixing auger to achieve the up-and-down stirring of the small materials and the aqueous solution. At the same time, the mixing rotating rod drives the mixing stirring forks to rotate horizontally, thereby improving the mixing effect of the small materials and the aqueous solution. The first mixing bracket drives the cleaning spiral blades to rotate, which can clean the inner wall of the mixing cylinder and avoid wasting small materials. By opening the second valve and using the pump body to generate a certain water pressure, it is convenient to pump the mixture of small materials and aqueous solution into the interior of the mixing device. Step 2: Utilize the characteristics that the reciprocating connecting shaft and reciprocating slider inside the reciprocating lifting ring are slidably connected to the reciprocating lead screw, so that the reciprocating lifting ring drives the mixing spiral blades and the mixing ring to move up and down. Through the characteristics that the lifting grooves inside the mixing ring are slidably connected to the lifting sliding rods, the stable lifting of the mixing ring can be achieved. At the same time, use the mixing blades at the top and bottom of the mixing ring to mix the raw materials. The valve piston inside the one-way valve can be pushed open by the ejecting springs and ejecting blocks on the outer side of the rotating ring, so that the mixed solution of small materials and water flows into the interior of the mixing device, thereby uniformly mixing the small material aqueous solution and the polycarboxylate water reducer, reducing the air content of the polycarboxylate water reducer, and thus improving the properties of the polycarboxylate water reducer. Step 3: By virtue of the feature that the starting limit chute is slidably connected to the ejection block in a limited manner, the up-and-down movement of the ejection block can be realized. At the same time, when the mixing ring rotates, the ejection block will not rotate together, avoiding the phenomenon that the ejection block is misaligned and causing the valve piston to be unable to eject. Start the first rotating motor to drive the rotating worm to rotate. By utilizing the meshing connection between the rotating worm and the rotating worm gear, the top rotating disk, the lifting sliding rod, and the bottom rotating disk are rotated, so as to mix the raw materials of the polycarboxylate superplasticizer. When adding the aqueous solution of the minor ingredient, the rapid mixing of the aqueous solution can be realized, thereby improving the full mixing of the aqueous solution of the minor ingredient and the polycarboxylate superplasticizer. Drive the reciprocating lead screw to rotate through the second rotating motor, and the up-and-down reciprocating movement of the entire mixing ring can be realized. It can not only add materials to different positions of the mixing device, but also improve the mixing effect of the polycarboxylate superplasticizer. By setting the feeding horizontal pipe and the vertical pipe, feeding can be carried out at different positions inside the mixing device. At the same time, by setting the one-way valve, under the action of the valve expansion rod and the valve spring, the valve piston is in close connection with the valve protrusion, thereby realizing the closing of the one-way valve, thus achieving the effect of quantitatively adding the minor ingredient, and at the same time preventing the polycarboxylate superplasticizer from entering the feeding horizontal pipe and the vertical pipe, thereby affecting the addition effect of the minor ingredient. Since the amount of the minor ingredient to be added is small, the minor ingredient and the polycarboxylate superplasticizer can be better mixed by means of layered addition, thereby reducing the air content of the polycarboxylate superplasticizer and improving the properties of the polycarboxylate superplasticizer.
[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: For the mixing equipment and its operation method for processing polycarboxylate superplasticizer, the raw materials are mixed by the mixing blades at the top and bottom of the mixing ring. The valve piston inside the one-way valve can be pushed open by the ejection spring and the ejection block on the outer side of the rotating ring, so that the mixed solution of the minor ingredient and water flows into the inside of the mixing device, thereby uniformly mixing the aqueous solution of the minor ingredient and the polycarboxylate superplasticizer. By virtue of the structural features of the mixing auger, the up-and-down agitation of the minor ingredient and the aqueous solution can be realized. At the same time, the mixing stirring fork is driven to rotate horizontally by the mixing rotating rod, thereby improving the mixing effect of the minor ingredient and the aqueous solution. Driving the cleaning spiral blade to rotate by the first mixing support can realize the cleaning of the inner wall of the mixing cylinder, avoiding the phenomenon of waste of the minor ingredient. The specific content is as follows: 1. By setting up the small material adding mechanism, not only can we utilize the characteristics that the reciprocating connecting shaft and the reciprocating slider inside the reciprocating lifting ring are slidably connected to the reciprocating lead screw, enabling the reciprocating lifting ring to drive the mixing spiral blade and the mixing ring to move up and down, but also through the characteristics that the lifting groove inside the mixing ring is slidably connected to the lifting sliding rod, the stable lifting of the mixing ring can be achieved. At the same time, the mixing blades at the top and bottom of the mixing ring are used to mix the raw materials. The valve piston inside the one-way valve can be pushed open by the ejecting spring and the ejecting block on the outside of the rotating ring, so that the mixed solution of small materials and water flows into the inside of the mixing device, thereby uniformly mixing the aqueous solution of small materials and the polycarboxylate water reducing agent, reducing the air content of the polycarboxylate water reducing agent, and thus improving the properties of the polycarboxylate water reducing agent. By starting the characteristics that the limit chute is slidably connected to the ejecting block, the up and down movement of the ejecting block can be achieved, and at the same time, when the mixing ring rotates, the ejecting block will not rotate together, avoiding the phenomenon that the ejecting block is misaligned and the valve piston cannot be ejected. Start the first rotating motor to drive the rotating worm to rotate, and utilize the characteristics of the meshing connection between the rotating worm and the rotating worm wheel to realize the rotation of the top rotating disc, the lifting sliding rod and the bottom rotating disc, thereby mixing the polycarboxylate water reducing agent raw materials. When adding the aqueous solution of small materials, the rapid mixing of the aqueous solution can be achieved, thus improving the full mixing of the aqueous solution of small materials and the polycarboxylate water reducing agent. By driving the reciprocating lead screw to rotate through the second rotating motor, the reciprocating up and down movement of the entire mixing ring can be achieved, which can not only add materials to different positions of the mixing device, but also improve the mixing effect of the polycarboxylate water reducing agent. By setting up the feeding horizontal pipe and the vertical pipe, materials can be added to different positions inside the mixing device. At the same time, by setting up the one-way valve, under the action of the valve expansion rod and the valve spring, the valve piston is in close connection with the valve protrusion, thereby realizing the closing of the one-way valve, thus achieving the effect of quantitatively adding small materials, and at the same time, the polycarboxylate water reducing agent will not enter the inside of the feeding horizontal pipe and the vertical pipe, thus affecting the adding effect of small materials. Since the amount of small materials to be added is small, the small materials and the polycarboxylate water reducing agent can be better mixed by the way of layered addition, thereby reducing the air content of the polycarboxylate water reducing agent and improving the properties of the polycarboxylate water reducing agent; 2. By setting up the minor ingredient mixing mechanism, not only can minor ingredients and aqueous solutions be injected into the mixing cylinder through the feed pipe and feed hopper, but also by starting the mixing motor to drive the rotation of the main mixing gear, and taking advantage of the meshing connection characteristics among the main mixing gear, the secondary mixing gear, and the meshing gear ring, while the meshing gear ring is fixed, not only can the secondary mixing gear drive the mixing tripod to revolve, but also the secondary mixing gear can rotate on its own axis, enabling the main mixing gear to drive the vertical rotating rod and the mixing auger to rotate. By virtue of the structural characteristics of the mixing auger, the up-and-down agitation of the minor ingredients and the aqueous solution can be achieved. At the same time, the mixing stirring fork is driven by the mixing rotating rod to rotate horizontally, thereby improving the mixing effect of the minor ingredients and the aqueous solution. By driving the cleaning spiral blade to rotate through the first mixing support, the cleaning of the inner wall of the mixing cylinder can be realized, avoiding the phenomenon of waste of minor ingredients. By opening the second valve and using the pump body to generate a certain water pressure, it is convenient to pump the mixture of minor ingredients and aqueous solution into the interior of the mixing device.

By providing the feeding horizontal pipe 124 and the vertical pipe 125, feeding can be carried out at different positions inside the mixing device 111. At the same time, by providing the one-way valve 127, under the action of the valve telescopic rod 130 and the valve spring 131, the valve piston 132 is brought into close contact with the valve projection 128, thereby closing the one-way valve 127, achieving the effect of quantitatively adding small materials, and preventing the polycarboxylate water reducer from entering the feeding horizontal pipe 124 and the vertical pipe 125, which may affect the addition effect of the small materials. Since the amount of small materials to be added is small, the small materials and the polycarboxylate water reducer can be better mixed by the method of layered addition, thereby reducing the air content of the polycarboxylate water reducer and improving the properties of the polycarboxylate water reducer.
[0031] Please refer to Figures 9 - 10, the small material mixing mechanism 2 includes a mixing cylinder 201. One side of the top of the mixing cylinder 201 is fixedly installed with a feed pipe 202.

The inner side of the top of the mixing cylinder 201 is fixedly installed with a fixed disk 205. The output end of the mixing motor 204 is fixedly connected with a mixing main gear 206. The outer side of the mixing main gear 206 is meshed with a mixing driven gear 207. The outer side of the mixing driven gear 207 is meshed with a meshing tooth ring 208.

The small materials and aqueous solution are injected into the mixing cylinder 201 by using the feed pipe 202 and the feed hopper 203. The mixing motor 204 is started to drive the mixing main gear 206 to rotate. By using the meshing connection characteristics among the mixing main gear 206, the mixing driven gear 207 and the meshing tooth ring 208, and with the meshing tooth ring 208 fixed, it can not only realize the revolution of the mixing driven gear 207 driving the mixing tripod 209, but also realize the rotation of the mixing driven gear 207 itself, so that the mixing main gear 206 drives the vertical rotating rod 210 and the mixing auger 211 to rotate.
[0032] Please refer to Figures 9 - 11, at the top and bottom of the vertical rotating rod 210, first mixing supports 212 are fixedly installed. Between the two first mixing supports 212, a cleaning spiral blade 213 is fixedly installed. The cleaning spiral blade 213 is in fitting connection with the inner wall of the mixing cylinder 201. On one side of the vertical rotating rod 210 close to the first mixing support 212, a second mixing support 214 is fixedly installed. Between the two second mixing supports 214, a mixing rotating rod 215 is fixedly installed. On the outer side of the mixing rotating rod 215, mixing stirring forks 216 are fixedly installed. At the bottom of the mixing cylinder 201, a second valve 217 is fixedly installed. The second valve 217 is fixedly connected to a pump body 218. The output end of the pump body 218 is fixedly connected to a connecting pipe 219. At the end of the connecting pipe 219, a connector 220 is fixedly installed. The connector 220 is fixedly installed at the top of the vertical pipe 125. At the bottom of the mixing cylinder 201, a support plate 222 is fixedly installed. Around the bottom of the support plate 222, support rods 221 are fixedly installed. The support rods 221 are fixedly installed at the top of the mixing device 111. By using the structural characteristics of the mixing auger 211, the up-and-down stirring of the small materials and the aqueous solution can be realized. At the same time, the mixing rotating rod 215 drives the mixing stirring forks 216 to rotate horizontally, thereby improving the mixing effect of the small materials and the aqueous solution. By driving the cleaning spiral blade 213 to rotate through the first mixing support 212, the cleaning of the inner wall of the mixing cylinder 201 can be realized, avoiding the phenomenon of waste of small materials. By opening the second valve 217 and using the pump body 218 to generate a certain water pressure, it is convenient to pump the mixture of the small materials and the aqueous solution into the interior of the mixing device 111.
[0033] Working principle: Before using this mixing equipment for processing polycarboxylate water reducer, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, use the feed pipe 202 and the feed hopper 203 to inject small materials and aqueous solution into the mixing cylinder 201. Start the mixing motor 204 to drive the rotation of the main mixing gear 206. Utilize the meshing connection characteristics among the main mixing gear 206, the driven mixing gear 207, and the meshing tooth ring 208. With the meshing tooth ring 208 fixed, not only can the driven mixing gear 207 drive the mixing tripod 209 to revolve, but also the driven mixing gear 207 can rotate itself, thereby driving the mixing and stirring fork 216 to rotate both around its own axis and revolve. By increasing the stirring method of the mixing and stirring fork 216, the mixing effect of the small materials and the aqueous solution can be improved. Make the main mixing gear 206 drive the vertical rotating rod 210 and the mixing auger 211 to rotate. Utilize the structural characteristics of the mixing auger 211 to realize the up-and-down stirring of the small materials and the aqueous solution. At the same time, drive the mixing and stirring fork 216 to rotate horizontally through the mixing rotating rod 215, thereby improving the mixing effect of the small materials and the aqueous solution. Drive the cleaning spiral blade 213 to rotate through the first mixing support 212, which can realize the cleaning of the inner wall of the mixing cylinder 201 and avoid the waste of small materials. By opening the second valve 217 and using the pump body 218 to generate a certain water pressure, it is convenient to pump the mixture of the small materials and the aqueous solution into the interior of the mixing device 111.
[0034] Secondly, utilize the characteristics that the reciprocating connecting shaft 102 and the reciprocating slider 103 inside the reciprocating lifting ring 101 are slidably connected to the reciprocating lead screw 123, so that the reciprocating lifting ring 101 drives the mixing spiral blade 104 and the mixing ring 105 to move up and down. Through the characteristics that the lifting groove 106 inside the mixing ring 105 is slidably connected to the lifting sliding rod 121, the stable lifting of the mixing ring 105 can be realized. At the same time, use the mixing blades 107 at the top and bottom of the mixing ring 105 to mix the raw materials. The valve piston 132 inside the one-way valve 127 can be pushed open by the ejecting spring 109 and the ejecting block 110 on the outer side of the rotating ring 108, so that the mixed solution of the small materials and water flows into the interior of the mixing device 111, thereby carrying out the uniform mixing of the small material aqueous solution and the polycarboxylate water reducer, reducing the air content of the polycarboxylate water reducer, and thus improving the properties of the polycarboxylate water reducer.
[0035] Finally, by virtue of the feature that the starting limit chute 112 is in limit sliding connection with the ejector block 110, the up-and-down movement of the ejector block 110 can be realized. Meanwhile, when the mixing ring 105 rotates, the ejector block 110 will not rotate together, avoiding the phenomenon that the ejector block 110 is misaligned and causing the valve piston 132 to be unable to eject. Start the first rotating motor 116 to drive the rotating worm 117 to rotate. Utilize the feature of the meshing connection between the rotating worm 117 and the rotating worm gear 118 to realize the rotation of the top rotating disc 120, the lifting sliding rod 121 and the bottom rotating disc 122, thereby mixing the raw materials of the polycarboxylate superplasticizer. When adding the small material aqueous solution, the rapid mixing of the aqueous solution can be realized, so as to improve the full mixing of the small material aqueous solution and the polycarboxylate superplasticizer. Drive the reciprocating lead screw 123 to rotate through the second rotating motor 119, and the up-and-down reciprocating movement of the entire mixing ring 105 can be realized. It can not only add materials to different positions of the mixing device 111, but also improve the mixing effect of the polycarboxylate superplasticizer. By setting the feeding horizontal pipe 124 and the vertical pipe 125, materials can be added to different positions inside the mixing device 111. At the same time, by setting the one-way valve 127, under the action of the valve telescopic rod 130 and the valve spring 131, the valve piston 132 is in fitting connection with the valve protrusion 128, thereby realizing the closing of the one-way valve 127, so as to achieve the effect of quantitatively adding small materials. At the same time, it will not cause the polycarboxylate superplasticizer to enter the feeding horizontal pipe 124 and the vertical pipe 125, thereby affecting the addition effect of the small materials. Since the amount of small materials to be added is small, the small materials and the polycarboxylate superplasticizer can be better mixed by the way of layered addition, thereby reducing the air content of the polycarboxylate superplasticizer and improving the properties of the polycarboxylate superplasticizer.
