[0029] 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.

[0030] Please see Figure 1-7 The present invention provides the following technical solution:

[0031] A storage tank for anti-settling polycarboxylate superplasticizer includes a storage tank body 1, a tank cover 3 on the top of the storage tank body 1, a stirring mechanism 5 inside the storage tank body 1, a heat preservation mechanism 9 inside the storage tank body 1, and temperature sensors 11 fixedly connected to both sides of the inner wall of the storage tank body 1. The stirring mechanism 5 includes a variable frequency motor 501, several stirring blades 502, a rotating rod 503, two stirring plates 504, and several stirring notches 505. The bottom of the variable frequency motor 501 is fixedly connected to the top of the storage tank body 1. Next, the bottom of the output shaft of the variable frequency motor 501 is fixedly connected to the top of the rotating rod 503, and the surface of the output shaft of the variable frequency motor 501 is movably connected to the interior of the storage tank 1. The stirring blade 502 is fixedly connected to the rotating rod 503 on the side near the rotating rod 503, and the stirring plate 504 is fixedly connected to the rotating rod 503 on the side near the rotating rod 503. The stirring notch 505 is opened inside the stirring plate 504. The two stirring plates 504 are inclined in opposite directions, and the stirring notches 505 inside the two stirring plates 504 are staggered.

[0032] In this embodiment: the controller 6 is connected to the variable frequency motor 501 and the electric heating wire 902 via an external connection cable. The controller 6 controls the variable frequency motor 501, which drives the rotating rod 503 to rotate the stirring blades 502 and the stirring plate 504. The two opposing inclined stirring plates 504 cooperate with the internal staggered stirring notches 505 to scrape up the sediment at the bottom of the storage tank 1 and guide it upward to the middle, where it is then uniformly mixed by the stirring blades 502, achieving three-dimensional stirring to prevent sedimentation. The water-based ceramic anti-stick coating on the surfaces of the rotating rod 503, stirring blades 502, and stirring plate 504, together with the polytetrafluoroethylene lining 903 on the inner wall of the storage tank 1, reduces surface energy, prevents sediment adhesion, and reduces residue. The temperature sensor 11 transmits the temperature signal to the controller 6 via wireless technology, automatically controlling the electric heating wire. Heating wire 902 maintains the polycarboxylate superplasticizer at 5-35℃ to prevent low-temperature crystallization and precipitation. Insulation cotton 901 slows down temperature loss, making it suitable for the storage and transportation of polycarboxylate superplasticizer in cold seasons. Operators can add superplasticizer by rotating the limit block 4 to open the tank lid 3. Forklifts can move the storage tank 1 through the fixing plate 19 and rubber anti-slip mat 17. Protective rubber 2 and fixing plate 19 prevent collisions between storage tanks 1 during transportation. The precipitation problem is solved by mechanical stirring, anti-stick coating and temperature control device. This solves the problem that the baffles in the existing patent are fixed, and the precipitates of polycarboxylate superplasticizer usually have a certain degree of adhesion and are easy to adhere to the surface of the baffle and are not easy to fall off, resulting in poor anti-precipitation effect of polycarboxylate superplasticizer. In addition, the storage tank does not receive anti-precipitation stirring during transportation.

[0033] Specifically, such as Figure 4 As shown, the insulation mechanism 9 includes insulation cotton 901, electric heating wire 902 and inner lining 903. The insulation cotton 901 is filled inside the storage tank 1. The electric heating wire 902 is disposed inside the storage tank 1 and is located on the side close to the inner wall of the storage tank 1. The inner lining 903 is formed on the inner wall of the storage tank 1 by coating with polytetrafluoroethylene.

[0034] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, the top of the storage tank 1 has an opening 18, the surface of the tank cover 3 is in contact with the inner wall of the opening 18, and a controller 6 is fixedly connected to the top of the storage tank 1.

[0035] In this embodiment: the heat preservation mechanism 9 is filled with heat preservation cotton 901 and combined with electric heating wire 902, which can effectively reduce heat loss and accurately control the temperature, ensuring that the polycarboxylate superplasticizer is at a suitable storage temperature. The polytetrafluoroethylene lining 903 reduces the surface energy of the inner wall of the storage tank 1, prevents sediment from adhering, improves cleaning convenience and storage anti-sedimentation stirring efficiency. The design of the top opening 18 and the tank cover 3 makes it convenient to open the tank cover 3 to add polycarboxylate superplasticizer into the storage tank 1. The controller 6 is connected to the frequency converter motor 501 and the electric heating wire 902 through an external connection line for convenient control.

[0036] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, rotating shafts 12 are fixedly connected to both sides of the top of the storage tank 1. Limiting blocks 4 are rotatably connected to the surface of the rotating shafts 12, and the bottom of the limiting blocks 4 is in close contact with the top of the tank cover 3.

[0037] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, magnetic blocks 14 are fixedly connected to both sides of the top of the can lid 3, the surface of the limiting block 4 is magnetically attracted to the surface of the magnetic blocks 14, and a lever 13 is fixedly connected to the top of the limiting block 4.

[0038] Specifically, such as Figure 1 and Figure 6 As shown, a sealing gasket 16 is fixedly connected to the bottom of the can lid 3, and the bottom of the sealing gasket 16 is in close contact with the top of the storage tank 1. A handle 15 is fixedly connected to the top of the can lid 3.

[0039] In this embodiment: by cooperating with the rotating shaft 12, the limiting block 4 and the magnetic block 14, the limiting block 4 can be disengaged from and contacted with the can lid 3 when it rotates, so that the can lid 3 can be opened quickly and closed tightly. The magnetic connection method avoids the limiting block 4 from rotating accidentally. The sealing gasket 16 enhances the sealing of the storage tank 1 and prevents the polycarboxylate superplasticizer from leaking. The handle 15 makes it easy to pull the can lid 3.

[0040] Specifically, such as Figure 2 and Figure 7 As shown, a fixing plate 19 is fixedly connected to the surface of the storage tank 1. There are four fixing plates 19, which are symmetrically distributed on the surface of the storage tank 1. A protective rubber 2 is fixedly connected to the top of the fixing plate 19, and a rubber anti-slip pad 17 is fixedly connected to the bottom of the fixing plate 19.

[0041] Specifically, such as Figure 3 As shown, a silicone block 10 is fixedly connected to the bottom of the storage tank 1. The number of silicone blocks 10 is several and they are evenly distributed at the bottom of the storage tank 1.

[0042] Specifically, such as Figure 2 As shown, a discharge pipe 7 is fixedly connected to the surface of the storage tank 1, and a valve body 8 is installed inside the discharge pipe 7.

[0043] In this embodiment: the symmetrically distributed fixing plate 19 and protective rubber 2 provide anti-collision protection for the storage tank 1 and facilitate contact between the external forklift equipment and the rubber anti-slip mat 17. The storage tank 1 is moved through the fixing plate 19. The combination design of the discharge pipe 7 and the valve body 8 realizes a precise and controllable discharge process and reduces residue.

[0044] Specifically, such as Figure 3 As shown, the surfaces of the stirring blade 502, the rotating rod 503, and the stirring plate 504 are all coated with a water-based ceramic anti-stick coating.

[0045] In this embodiment, the water-based ceramic anti-stick coating on the surfaces of the stirring blades 502, the rotating rod 503, and the stirring plate 504 significantly reduces the material adhesion rate, improves stirring efficiency and uniformity, reduces cleaning frequency and residue, and extends the equipment maintenance cycle.

[0046] Working principle: The controller 6 is connected to the variable frequency motor 501 and the electric heating wire 902 via an external connection cable. The controller 6 controls the variable frequency motor 501, causing the output shaft of the variable frequency motor 501 to drive the rotating rod 503, which in turn drives the stirring blades 502 and the stirring plates 504 to rotate. The two opposing inclined stirring plates 504, together with the internally staggered stirring notches 505, scrape the sediment at the bottom of the storage tank 1 during rotation, and use the inclined angle to guide the sediment upward to the middle of the storage tank 1, where the stirring blades 502 mix it evenly, achieving three-dimensional stirring and anti-sedimentation of the polycarboxylate superplasticizer. The rotating rod 503... The water-based ceramic anti-stick coating on the surfaces of the stirring blades 502 and the agitator plate 504, along with the polytetrafluoroethylene lining 903 coating on the inner wall of the storage tank 1, collectively reduce surface energy, preventing the adhesion of polycarboxylate superplasticizer precipitates, ensuring the anti-precipitation effect of the stirring and reducing polycarboxylate superplasticizer precipitate residue. The temperature sensor 11 monitors the tank temperature in real time and transmits the signal to the controller 6 via existing mature wireless connection technology. The controller 6 automatically controls the electric heating wire 902 to operate according to the preset temperature range, maintaining the superplasticizer at a suitable temperature, typically 5-35℃, to avoid low-temperature crystallization leading to precipitation. The insulation cotton 901 slows down temperature dissipation. This design is particularly suitable for the storage and transportation of polycarboxylate superplasticizers in cold seasons. The silicone block 10 at the bottom of the storage tank 1 provides anti-slip and stable support, making the storage tank 1 more stable. During use, the operator can rotate the limiting block 4 to disengage from the magnetic block 14 and the tank lid 3, and hold the handle 15 to open the tank lid 3 upwards, adding polycarboxylate superplasticizer through the top opening 18. During handling, an external forklift can stably lift the storage tank 1 using the fixing plate 19 and the rubber anti-slip pad 17. The protective rubber 2 prevents collisions and friction during transportation and placement of the storage tank 1. When discharge is required, the valve 8 on the discharge pipe 7 can be opened to complete the unloading. By combining mechanical stirring, anti-stick coating, and temperature control device, the sedimentation problem of polycarboxylate superplasticizer during storage is solved. This addresses the issue that existing patents use fixed baffles, where polycarboxylate superplasticizer sediments tend to adhere to the baffle surface and are difficult to remove, resulting in poor sedimentation prevention. Furthermore, the storage tank does not receive sedimentation prevention stirring during transportation. It should be noted that the controller 6, variable frequency motor 501, temperature sensor 11, and electric heating wire 902 are all existing and published mature technologies, and are powered by an external power supply. Their basic mechanisms will not be elaborated here.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
