These devices are used to precisely add polycarboxylate superplasticizer during the concrete production process. Polycarboxylate superplasticizer is a commonly used and highly efficient water-reducing agent that can significantly improve the fluidity and strength of concrete, while maintaining or improving its workability while reducing water usage.

[0003] A search revealed Chinese Patent Publication No. CN219092232U, which discloses a polycarboxylate superplasticizer feeding device. This device relates to the field of polycarboxylate superplasticizer feeding, and includes a feeding box. Feed pipes are fixedly connected to both sides of the upper surface of the feeding box. Weighing plates are fixedly connected to the upper sides of both sides of the inner wall of the feeding box. Electric telescopic rods are fixedly connected to the upper sides of both sides of the inner wall of the feeding box. Push plates are fixedly connected to the output ends of the two electric telescopic rods. This invention can control the feeding of polycarboxylate superplasticizer through a weighing sensor, achieving precise quantitative control. Furthermore, a motor-driven crushing roller pulverizes and grinds the polycarboxylate superplasticizer, ensuring high pulverization efficiency and a better pulverization effect. This reduces manual labor, improves the quantitative accuracy and efficiency of polycarboxylate superplasticizer feeding, and guarantees the quality of polycarboxylate superplasticizer use, making it highly practical.

However, in actual operation, the feeding and unloading of polycarboxylate superplasticizer cannot be precisely controlled, resulting in an inaccurate ratio of polycarboxylate superplasticizer. Therefore, a polycarboxylate superplasticizer feeding device is proposed to solve the above problems. Utility Model Content

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the intelligent sensor of motor one controls the output weight to ensure that the output weight is uniform and accurate each time. The cylinder one is started to push the telescopic shaft one to slide inside the feed pipe, so that the sliding block moves backward.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1 to 3 This utility model provides an embodiment of a polycarboxylate superplasticizer feeding device, including a support frame 1, which serves as the basic support structure for the entire feeding device. It supports the feeding mechanism 2, the discharge assembly 29, and the mixing mechanism 4, ensuring the overall stability of the device and allowing it to maintain a fixed position during operation. This prevents the device from shaking or tipping due to external forces or its own weight, thus ensuring the smooth operation of feeding, discharging, and mixing. The feeding mechanism 2 is fixedly connected inside the support frame 1. The feeding mechanism 2 includes a storage tank 21 for storing polycarboxylate superplasticizer, providing raw materials for subsequent feeding operations. Its capacity is determined according to actual production needs, meeting the feeding requirements for a certain period, reducing the frequency of raw material replenishment, and improving work efficiency. The top of the storage tank 21 is fixedly connected inside the support frame 1, and two feed pipes 22 are fixedly connected to the top of the storage tank 21. The feed pipes 22 serve as… The feed pipe 22 serves as a channel for raw materials to enter the storage tank 21, delivering external polycarboxylate superplasticizer into the tank 21. This helps control the entry speed and flow rate of the raw materials, ensuring the stability and accuracy of the feeding process. Two fixed blocks 23 are fixedly connected inside the feed pipe 22. A telescopic column 24 is fixedly connected to the bottom of each fixed block 23. A spring 25 is sleeved on the outside of the telescopic column 24, and a piston 26 is fixedly connected to the other end of the telescopic column 24. This gives the feed pipe 22 a certain buffering and regulating function. When raw materials enter the feed pipe 22, the piston 26 compresses the spring 25 under the pressure of the raw materials. The telescopic column 24's extension and retraction movement regulates the pressure and flow rate inside the feed pipe 22, thereby controlling the feeding speed. Simultaneously, the elasticity of the spring 25 can reduce the impact force generated when the raw materials enter, protecting the structure of the feed pipe 22 and the storage tank 21. A drive assembly 27 is fixedly connected inside the feed pipe 22.

[0041] Specifically, during operation, polycarboxylate superplasticizer enters the feed pipe 22 through an external conveying device. As the raw material flows in, the piston 26 is pressurized, compressing the spring 25 and causing the telescopic column 24 to extend and retract, adjusting the pressure and flow rate within the feed pipe 22 to achieve accurate control of the feeding speed. Simultaneously, the elasticity of the spring 25 effectively buffers the impact force generated when the raw material enters, protecting the structure of the feed pipe 22 and the storage tank 21. After the raw material smoothly enters the storage tank 21, the feeding mechanism 2, according to production needs, conveys the polycarboxylate superplasticizer in the storage tank 21 to the mixing mechanism 4. Under the action of the mixing mechanism 4, it is fully mixed with other materials. The mixed material is finally discharged through the discharge component 29, completing the entire feeding, mixing, and discharging process.

[0042] The drive assembly 27 includes a cylinder 271, which is externally fixedly connected to the inside of the feed pipe 22 to provide power for the movement of the telescopic shaft 272. The drive end of the cylinder 271 is fixedly connected to the telescopic shaft 272. By controlling the telescopic movement of the telescopic shaft 272, the sliding block 273 is driven to slide within the feed pipe 22, thereby controlling the flow of raw materials within the feed pipe 22. The sliding block 273 is externally fixedly connected to the telescopic shaft 272, and the external surface of the sliding block 273 is slidably connected to... Inside the feed pipe 22, when the telescopic shaft 272 extends, the sliding block 273 moves toward the outlet of the feed pipe 22, opening the channel so that the raw material can smoothly enter the storage tank 21. When the telescopic shaft 272 retracts, the sliding block 273 moves toward the inlet of the feed pipe 22, closing the channel and preventing the raw material from continuing to enter. This allows the sliding block 273 to fit tightly against the inner wall of the feed pipe 22, achieving good sealing performance and ensuring accurate control of the raw material flow. The bottom of the support frame 1 is fixedly connected to the discharge pipe 28, and the outside of the storage tank 21 is fixedly connected to the discharge assembly 29.

[0043] Specifically, firstly, the external polycarboxylate superplasticizer enters the device through the feed pipe 22. At this time, cylinder 271 is activated, driving telescopic shaft 272 to extend and retract. When telescopic shaft 272 extends, sliding block 273 moves towards the outlet of feed pipe 22, opening the channel. The raw material smoothly enters storage tank 21 under pressure. When it is necessary to stop feeding, cylinder 271 drives telescopic shaft 272 to retract, and sliding block 273 moves towards the inlet of feed pipe 22, tightly fitting the inner wall of feed pipe 22, closing the channel, and preventing... The material flow is accurately controlled by stopping the material from entering. When the polycarboxylate superplasticizer stored in the storage tank 21 is needed, it is discharged through the discharge component 29. The discharge component 29 is connected to the storage tank 21 to ensure that the material can flow smoothly from the storage tank 21 to the discharge pipe 28 and finally be discharged from the device through the discharge pipe 28, thus completing the feeding operation. The drive component 27 controls the movement of the telescopic shaft 272 and the sliding block 273 to accurately control the inflow and stop of the material, ensuring the stability and accuracy of the feeding process and meeting production needs.

[0044] The discharge assembly 29 includes a weight intelligent sensor 291, which monitors the weight of the polycarboxylate superplasticizer in the storage tank 21 in real time. By observing the weight changes, the amount of superplasticizer discharged can be accurately calculated, thereby achieving accurate control of the discharge amount. The weight intelligent sensor 291 is externally fixedly connected to the outside of the feed pipe 22. A wire 292 is fixedly connected to the output end of the weight intelligent sensor 291, and a motor 293 is fixedly connected to the other end of the wire 292. The motor 293 controls the rotation of the rotating shaft 294 based on the signal transmitted by the weight intelligent sensor 291, thereby driving the rotating plate 295 to rotate inside the discharge pipe 28, thus adjusting the discharge amount. The drive end of the motor 293 is fixedly connected to a rotating shaft 294. Shaft 294 is externally fixedly connected to a rotating plate 295. When motor 293 starts, it drives the rotating shaft 294 to rotate, causing the rotating plate 295 to open the discharge channel, allowing the polycarboxylate superplasticizer to flow out from the discharge pipe 28. When the weight reaches the predetermined discharge amount, motor 293 stops working, rotating plate 295 closes the discharge channel, and discharge stops. Support plate 3 is fixedly connected to the lower internal end of support frame 1. Support plate 3 is fixedly connected to the lower internal end of support frame 1 to provide an installation base for mixing mechanism 4, ensuring the stability and positional accuracy of mixing mechanism 4. Support plate 3 also plays a certain supporting and bearing role, bearing the weight of mixing mechanism 4 and various forces generated during the mixing process. Mixing mechanism 4 is fixedly connected to the top of support plate 3.

[0045] Specifically, firstly, the intelligent weight sensor 291 monitors the weight of the polycarboxylate superplasticizer in the storage tank 21 in real time. When discharge is required, the motor 293 starts, driving the rotating shaft 294 to rotate, which in turn drives the rotating plate 295 to rotate in the discharge pipe 28, opening the discharge channel. The polycarboxylate superplasticizer flows out from the discharge pipe 28. The intelligent weight sensor 291 calculates the amount of superplasticizer discharged by monitoring the weight change. When the weight reaches the predetermined discharge amount, the motor 293 stops working, the rotating plate 295 closes the discharge channel, and the discharge stops. Subsequently, the superplasticizer in the storage tank 21 enters the mixing mechanism 4 through the discharge pipe 28. The mixing mechanism 4 works under the support of the support plate 3 to mix the superplasticizer with other materials.

[0046] Reference Figure 4 and Figure 5The mixing mechanism 4 includes a second cylinder 41, which provides power to the mixing mechanism 4. Through the telescopic movement of the second telescopic shaft 42, the connecting plate 43 moves up and down, thereby realizing the scraping of the inner wall of the storage tank 21 by the scraper 46 and the up and down movement of the stirring plate 473 and the mixing plate 474, so that the polycarboxylate superplasticizer is fully mixed in the storage tank 21. The bottom of the second cylinder 41 is fixedly connected to the top of the support plate 3. The driving end of the second cylinder 41 is fixedly connected to the second telescopic shaft 42. The outside of the telescopic shaft 42 is fixedly connected to the connecting plate 43. The top of the connecting plate 43 is fixedly connected to multiple connecting rods. The top of the connecting rod 44 is fixedly connected to a ring 45, and the bottom of the ring 45 is fixedly connected to a scraper 46. Driven by the second cylinder 41, the scraper 46 moves up and down along the inner wall of the storage tank 21 to scrape off the polycarboxylate superplasticizer adhering to the tank wall, preventing the raw material from remaining and clumping on the tank wall, ensuring that the raw material can be fully mixed and flow out smoothly. The scraper 46 can closely fit the inner wall of the storage tank 21 and can move up and down reciprocating under the drive of the second cylinder 41 to effectively scrape the tank wall. The top of the storage tank 21 is fixedly connected to a power assembly 47.

[0047] Specifically, firstly, cylinder 41 is activated, and the telescopic movement of telescopic shaft 42 drives the connecting plate 43 to move up and down. The movement of the connecting plate 43 is transmitted to the ring 45 through multiple connecting rods 44, which in turn drives the scraper 46 to move up and down along the inner wall of the storage tank 21, scraping off the polycarboxylate superplasticizer adhering to the tank wall to prevent raw material residue and agglomeration. At the same time, the power unit 47 starts working, driving the stirring plate 473 and the mixing plate 474 to rotate and stir. The movement of the scraper 46 works in conjunction with the up and down movement of the scraper 46 to ensure that the polycarboxylate superplasticizer is fully mixed in the storage tank 21. Throughout the process, cylinder 41 provides power to ensure the coordinated movement of the scraper 46, stirring plate 473 and mixing plate 474, completing the mixing of the polycarboxylate superplasticizer and ensuring the subsequent discharge operation.

[0048] The power assembly 47 includes a second motor 471, which drives a second rotating shaft 472 to rotate, thereby driving the stirring plates 473 and mixing plates 474 to rotate within the storage tank 21. This further promotes the uniformity of mixing the polycarboxylate superplasticizer. The bottom of the second motor 471 is fixedly connected to the storage tank 21, and the driving end of the second motor 471 is fixedly connected to the second rotating shaft 472. Multiple stirring plates 473 are fixedly connected to the outside of the second rotating shaft 472. The rotational motion of the stirring plates 473 and mixing plates 474, combined with the up-and-down scraping motion of the scraper 46, achieves an all-around mixing effect, ensuring that the raw materials are fully mixed within the storage tank 21, thus improving the quality and performance of the superplasticizer. Multiple mixing plates 474 are fixedly connected to the outside of the second rotating shaft 472. The shape and angle of the mixing plate 474 can produce a good stirring and mixing effect, so that the polycarboxylate superplasticizer can be fully turned over and mixed during rotation. One end of the spring 25 is fixedly connected to the top of the piston 26, and the other end of the spring 25 is fixedly connected to the bottom of the fixed block 23. The outside of the rotating plate 295 is rotatably connected to the inside of the discharge pipe 28. Driven by the motor 293, the rotating plate 295 rotates in the discharge pipe 28 to control the opening and closing of the discharge channel and realize the adjustment of the discharge amount. Its rotation angle and speed directly affect the size and stability of the discharge amount. The inside of the discharge pipe 28 is slidably connected to the outside of the rotating shaft 294. The outside of the ring 45 is slidably connected to the inside of the storage tank 21. The inner wall of the storage tank 21 is slidably connected to the outside of the scraper 46.

[0049] Specifically, motor 2471 starts, driving rotating shaft 2472 to rotate, which in turn drives stirring plate 473 and mixing plate 474 to rotate inside storage tank 21, realizing the stirring and mixing of polycarboxylate superplasticizer. At the same time, cylinder 241 works, telescopic shaft 242 extends and retracts, driving connecting plate 43 to move up and down. Through connecting rod 44 and ring 45, scraper 46 scrapes up and down along the inner wall of storage tank 21, scraping off the attached raw material, further promoting the uniformity of mixing. When discharge is required, motor 293 starts, driving rotating shaft 294 to rotate, driving rotating plate 295 to rotate inside discharge pipe 28, opening the discharge channel, and polycarboxylate superplasticizer flows out. Weight intelligent sensor 291 monitors the weight of raw material in storage tank 21 in real time and controls the discharge amount. Spring 25 connects piston 26 and fixing block 23 to provide buffer for the discharge process.

[0050] Working principle: First, the raw material for making polycarboxylate superplasticizer enters the storage tank 21 through the feed pipe 22. Upon entry, the actuating cylinder 271 pushes the telescopic shaft 272 to slide inside the feed pipe 22, causing the sliding block 273 to move backward. The pressure generated inside the feed pipe 22 causes the piston 26 at the upper end of the feed pipe 22 to slide downward, pulling the spring 25 upward. Thus, the raw material at the upper end of the feed pipe 22 is transported through the gap between the fixing block 23 and the piston 26 to the middle of the feed pipe 22. Then, cylinder 271 is activated again, pushing telescopic shaft 272 to drive sliding block 273 forward, causing a change in pressure. This causes piston 26 at the lower end of feed pipe 22 to be squeezed downwards, and spring 25 pulls the raw material from the gap between fixed block 23 at the lower end of feed pipe 22 and piston 26 into the storage tank 21. Meanwhile, the spring 25 at the upper end of feed pipe 22, under the reaction force of its own elasticity, causes piston 26 to be sealed inside fixed block 23.

[0051] Then, motor 2471 is started to drive rotating shaft 2472 to rotate, which in turn drives stirring plate 473 and mixing plate 474. Multiple circular holes are made on the surface of mixing plate 474 to ensure more thorough mixing of the solution inside storage tank 21. Then, motor 1293 is started to drive rotating shaft 1294 to drive rotating plate 295 to rotate, quantitatively discharging the well mixed polycarboxylate superplasticizer inside storage tank 21. The starting of motor 1293 is intelligently detected by weight intelligent sensor 291, which drives motor 1293 to start, so that the weight of the discharged material is uniform.

[0052] During discharge, the telescopic shaft 42 is activated to drive the connecting plate 43 and connecting rod 44 to slide inside the storage tank 21. This allows the connecting rod 44 to transmit vertical force to the ring 45 inside the storage tank 21, causing the ring 45 to slide inside the storage tank 21. The ring 45 then slides on the inner wall of the storage tank 21, scraping the residual polycarboxylate superplasticizer on the inner wall of the storage tank 21 to the bottom, thus avoiding waste.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
