Technical Field

[0001] This utility model belongs to the technical field of water-reducing agent production equipment, specifically relating to a polycarboxylate water-reducing agent storage device. Background Technology

[0002] Water-reducing agents are concrete admixtures that can reduce the amount of mixing water while maintaining the slump of concrete. When added to concrete mixtures, they disperse cement particles, improve workability, reduce unit water consumption, improve the fluidity of concrete mixtures, or reduce unit cement consumption, thus saving cement.

[0003] After the production of polycarboxylate superplasticizer is completed, it needs to be stored and transported using storage devices. Existing storage devices lack fixed devices, and during the movement, the storage devices are prone to shaking or tilting, which can lead to leakage of polycarboxylate superplasticizer in the tank and affect the normal transportation of polycarboxylate superplasticizer. In addition, when polycarboxylate superplasticizer products are left to stand for a long time, sedimentation or stratification will occur, affecting the uniformity and performance stability of the product. Utility Model Content

[0004] To overcome the problems of existing polycarboxylate superplasticizer storage devices, such as tank shaking or tilting due to lack of a fixed structure during movement, leading to liquid leakage, and the tendency for sedimentation or stratification to occur during prolonged standing, thus affecting product uniformity and performance stability, this invention provides a polycarboxylate superplasticizer storage device. This device improves transport stability by optimizing the tank's fixing method and adding a flexible fixing mechanism. Furthermore, it achieves uniform mixing of the liquid within the tank through a stirring mechanism, reducing sedimentation and stratification.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A polycarboxylate superplasticizer storage device mainly includes a movable base, a storage tank, a flexible fixing mechanism, and a stirring mechanism. The movable base includes a bottom support frame, support wheels, a handrail frame, and casters. Support wheels are installed at the ends of the bottom support frame, and a handrail frame is provided at the ends. An annular groove is provided in the middle of the bottom support frame, and an annular buffer pad is adhered to the inner wall of the annular groove. Multiple casters are evenly spaced at the bottom of the annular groove. The lower part of the storage tank is nested in the annular groove, and the annular buffer pad and the annular caster are connected by the annular groove. The grooves fit tightly together to form a fixed connection. The flexible fixing mechanism includes an adjustable tension strap and a self-locking hook assembly. The adjustable tension strap is set around the outer wall of the liquid storage tank, and both ends are connected to the handrail frame through the self-locking hook assembly. The top of the liquid storage tank is equipped with a cover, and the side wall is equipped with an inlet pipe and an outlet pipe. The inlet pipe extends to the outside of the liquid storage tank and connects to an inverted conical inlet hopper. The side wall of the annular slot has a rectangular notch, and the outlet pipe extends to the outside of the annular slot through the rectangular notch. The inlet pipe and outlet pipe are respectively equipped with an inlet valve and an outlet valve. The stirring mechanism is installed on the cover and extends into the inside of the liquid storage tank.

[0006] The stirring mechanism includes a motor, a rotating shaft, a stirring paddle, stirring blades, and a spiral stirring blade. The motor is installed at the top of the cover, and the rotating shaft is rotatably installed on the cover through bearings. The rotating shaft is connected to the output end of the motor. The stirring paddle is installed at the bottom of the rotating shaft, and the stirring blades are evenly spaced and distributed along the axial direction on the rotating shaft. The spiral stirring blades are staggered and welded to the rotating shaft to form a multi-stage stirring structure with the stirring blades.

[0007] The adjustable tensioning strap is made of elastic nylon braided strap, with an anti-slip silicone layer on the inside.

[0008] The annular buffer pad is made of rubber or silicone and is fixed to the inner wall of the annular slot by adhesive bonding.

[0009] The beneficial effects of this utility model are:

[0010] The combination of the bottom support frame and the annular groove, along with the double fixing effect of the flexible fixing mechanism, significantly improves the stability of the liquid storage tank during transportation, reduces the risk of shaking and tilting, and effectively avoids liquid leakage. At the same time, the stirring mechanism can form a complex flow field distribution in the liquid storage tank, which can fully mix the upper and lower layers of liquid, solve the problem of sedimentation and stratification caused by long-term standing, and ensure the uniformity and performance stability of the product.

Detailed Implementation

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a polycarboxylate superplasticizer storage device. The polycarboxylate superplasticizer storage device mainly includes a movable base 1, a storage tank 2, a flexible fixing mechanism 3, and a stirring mechanism 4. The movable base 1 is composed of a bottom support frame 11, support wheels 12, a handrail frame 13, and casters 14. Support wheels 12 are installed at the ends of the bottom support frame 11 to support the weight of the entire device. The handrail frame 13 is located at the end of the bottom support frame 11 to facilitate the operator to push the device to move. An annular groove 15 is provided in the middle of the bottom support frame 11. An annular buffer pad is adhered to the inner wall of the annular groove 15. The annular buffer pad is made of rubber or silicone material and is fixed to the inner wall of the annular groove 15 by adhesive to enhance the fixing effect on the storage tank 2 and reduce transportation vibration. Multiple casters 14 are evenly spaced at the bottom of the bottom support frame 11 for flexible adjustment of the movement direction.

[0020] like Figure 2 , Figure 3 , Figure 5As shown, the lower part of the storage tank 2 is nested in the annular groove 15, and is fixedly connected to the annular groove 15 by a tight fit of the annular buffer pad. The top of the storage tank 2 is provided with a cover 21, and the side wall is provided with a feed pipe 22 and a discharge pipe 23. The feed pipe 22 extends to the outside of the storage tank 2 and is connected to an inverted conical feed hopper 24. The conical design of the inverted conical feed hopper 24 can guide the material to flow quickly into the interior of the storage tank 2 and avoid material residue. The side wall of the annular groove 15 is provided with a rectangular notch 17, and the discharge pipe 23 extends to the outside of the annular groove 15 through the rectangular notch 17 to facilitate material discharge. The feed pipe 22 and the discharge pipe 23 are respectively equipped with a feed valve 25 and a discharge valve 26. Both the feed valve 25 and the discharge valve 26 are manual ball valves, which are easy to operate and have good sealing performance.

[0021] like Figure 4 As shown, the flexible fixing mechanism 3 includes an adjustable tension strap 31 and a self-locking hook assembly 32. The adjustable tension strap 31 is arranged around the outer wall of the liquid storage tank 2, and its two ends are connected to the handrail 13 through the self-locking hook assembly 32. The adjustable tension strap 31 is made of elastic nylon braided strap, and its inner side is provided with an anti-slip silicone layer. The anti-slip silicone layer is combined with the inner side of the adjustable tension strap 31 through a hot pressing process to enhance the friction with the outer wall of the liquid storage tank 2 and prevent slippage. The self-locking hook assembly 32 is used to adjust the tightness of the adjustable tension strap 31 to ensure that the liquid storage tank 2 remains stable during transportation.

[0022] like Figure 5 , Figure 6 As shown, the stirring mechanism 4 is installed on the cover 21 and extends into the liquid storage tank 2 to stir the liquid in the tank. The stirring mechanism 4 includes a motor 41, a rotating shaft 42, a stirring paddle 43, stirring blades 44, and a spiral stirring blade 45. The motor 41 is installed at the top of the cover 21. The rotating shaft 42 is rotatably installed on the cover 21 through bearings. The output end of the rotating shaft 42 and the motor 41 are connected by a coupling. The stirring paddle 43 is welded to the bottom of the rotating shaft 42 to fully stir the liquid at the bottom of the tank. The stirring blades 44 are welded at equal intervals on the rotating shaft 42 and distributed along the axial direction of the rotating shaft 42. The spiral stirring blades 45 are welded alternately on the rotating shaft 42, forming a multi-stage stirring structure with the stirring blades 44 to improve the fluidity and mixing uniformity of the liquid.

[0023] In practical use, the operator injects the polycarboxylate superplasticizer into the storage tank 2 through the inverted conical feed hopper 24, and opens the feed valve 25 to control the material flow. The storage tank 2 is fixedly connected to the bottom support frame 11 through the annular groove 15. At the same time, the adjustable tension strap 31 in the flexible fixing mechanism 3 further enhances the fixing effect. When it is necessary to move the device, the operator pushes the device through the handrail 13. The casters 14 and the support wheels 12 work together to make the device move smoothly. During the long-term static process, the motor 41 is started to drive the rotating shaft 42 to rotate. The stirring paddle 43, stirring blade 44 and spiral stirring blade 45 on the rotating shaft 42 work together to fully mix the upper and lower layers of liquid in the storage tank 2, reducing the occurrence of sedimentation and stratification. When discharging, the discharge valve 26 is opened and the liquid is discharged from the device through the discharge pipe 23. The above-described structure ensures the stability of the storage tank 2 during transportation, preventing the risks of shaking and tilting. Simultaneously, the stirring mechanism 4 effectively addresses sedimentation and stratification issues caused by prolonged standing, guaranteeing product uniformity and performance stability. The introduction of annular buffer pads and anti-slip silicone layers enhances the device's shock resistance and reliability, adapting to the needs of various complex transportation environments.

[0024] Work process:

[0025] First, during the installation of the storage tank 2, the operator nests the lower part of the storage tank 2 into the annular groove 15. The annular buffer pad is fixed to the inner wall of the annular groove 15 by adhesive bonding, which can effectively absorb the vibration and impact during transportation and protect the storage tank 2 from damage. After the storage tank 2 is embedded in the annular groove 15, the annular buffer pad fits tightly against the outer wall of the storage tank 2, forming an initial fixed connection. Subsequently, the operator uses the flexible fixing mechanism 3 to further enhance the fixing effect of the storage tank 2. As a result, the adjustable tension strap 31 is installed around the outer wall of the liquid storage tank 2, and both ends are connected to the handrail 13 through the self-locking hook assembly 32. During this process, the operator can adjust the tightness of the adjustable tension strap 31 through the self-locking hook assembly 32 to ensure that the liquid storage tank 2 remains stable during transportation. The anti-slip silicone layer on the inner side of the adjustable tension strap 31 is combined with the nylon braided strap through a hot pressing process, which enhances the friction with the outer wall of the liquid storage tank 2 and effectively prevents the liquid storage tank 2 from shifting due to shaking during transportation.

[0026] During the feeding stage, the operator pours the polycarboxylate superplasticizer into the inverted conical feed hopper 24. Its conical design guides the material to flow quickly into the storage tank 2, reducing material residue. At this time, the operator opens the feed valve 25 to control the material flow rate. After feeding is completed, the feed valve 25 is closed to ensure the sealing of the storage tank 2. During the long-term standing process, the motor 41 is started to drive the rotating shaft 42 to rotate. The stirring paddle 43 mainly stirs the liquid at the bottom of the tank to prevent sedimentation. The stirring blade 44 improves the vertical flow of the liquid through radial distribution, while the spiral stirring blade 45 promotes the axial flow of the liquid through its spiral structure. The three work together to form a complex flow field distribution, which fully mixes the upper and lower layers of liquid in the storage tank 2, thereby reducing sedimentation and stratification.

[0027] When the device needs to be moved, the operator pushes the device through the handrail 13. The casters 14 and support wheels 12 work together to move the device smoothly. The rectangular frame structure of the bottom support frame 11 provides stable support for the entire device. The design of the annular groove 15 and the annular buffer pad further enhances the fixing effect of the liquid storage tank 2. During the movement, the adjustable tension strap 31 and the self-locking hook assembly 32 in the flexible fixing mechanism 3 work together to ensure that the liquid storage tank 2 will not be displaced due to shaking or tilting.

[0028] During the discharge stage, the operator opens the discharge valve 26, and the liquid in the storage tank 2 is discharged through the discharge pipe 23. The discharge pipe 23 extends to the outside through the rectangular notch 17 on the side wall of the annular groove 15 to facilitate material discharge. The discharge valve 26 also adopts a manual ball valve design, which is easy to operate and has good sealing performance. After the discharge is completed, the discharge valve 26 is closed to ensure the sealing of the storage tank 2.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
