Description

Technical Field

[0001] The present invention relates to the technical field of storage tanks, and more particularly to a storage tank for concrete admixtures that prevents sediment accumulation. Background Art

[0002] Currently, mixing stations for producing commercial concrete need to use a large amount of concrete admixtures to improve the performance of concrete. The admixtures are usually stored in large storage tanks and are transported into the concrete through the storage tanks during use. Generally, the concrete admixtures in the large storage tanks can be used for a long time. Due to long-term placement, the admixtures in the storage tanks are prone to sedimentation at the bottom of the tank and accumulate inside the tank body, causing blockage during use. Moreover, the sedimentation of the admixtures in the storage tank results in inconsistent concentrations of the admixtures at different positions in the tank. When the admixtures with uneven concentrations are used for concrete mixing, it will directly affect the uniformity and performance of the concrete. The sedimented admixtures require a longer mixing time to be evenly distributed again, which increases the difficulty and time cost of mixing. During the construction process, the concrete mixed with sedimented and uneven admixtures is prone to quality problems. To prevent sediment accumulation of the admixtures, regular stirring is usually adopted, and the storage tank is regularly monitored and managed. However, when using regular stirring, it is necessary to remix the sedimented admixtures evenly, and a single stirring method is difficult to achieve sufficient stirring. Therefore, it is necessary to provide a storage tank for concrete admixtures that prevents sediment accumulation to solve the problems raised in the above background art. Summary of the Invention

[0003] To achieve the above object, the present invention provides the following technical solution: A storage tank for concrete admixtures that prevents sediment accumulation, comprising:

[0004] A fixing frame for carrying the concrete admixture storage tank;

[0005] A storage tank fixed on the fixing frame;

[0006] A central stirring device disposed in the middle of the storage tank;

[0007] An outer ring stirring device disposed inside the storage tank and rotatably connected to the inner wall of the storage tank;

[0008] Adjusting and mixing devices, a plurality of which are annularly distributed, disposed inside the storage tank and located between the central stirring device and the outer ring stirring device;

[0009] A control device fixed on the top of the storage tank and connected to the top of the adjusting and mixing device.

[0010] Further, as a preference, the storage tank includes:

[0011] A protective tank body fixed on the fixing frame;

[0012] A storage tank body, coaxially arranged with the protection tank body and fixed inside the protection tank body;

[0013] A circulation assembly, arranged between the bottom and the side of the protection tank body and the storage tank body;

[0014] A discharge port, in a concave shape, arranged at the center of the bottom of the storage tank body;

[0015] A discharge pipe, one end of which is fixed at the bottom of the discharge port and the other end communicates with the center of the bottom of the protection tank body;

[0016] A fixed top cover, fixed at the top of the protection tank body and the storage tank body;

[0017] A feed port, fixed on the fixed top cover and located at the top of the storage tank body.

[0018] That is to say, the concrete admixture is injected into the storage tank body through the feed port for storage. Under the action of the central stirring device and the outer ring stirring device, the admixture inside the storage tank body is stirred, effectively reducing the probability of sedimentation of the admixture inside the storage tank body. And the admixture solution inside the storage tank body is extracted by the circulation assembly and then conveyed into the storage tank body from the bottom of the storage tank body. Under the cooperation of the regulating and mixing device, the flow direction of the solution is dispersed, promoting the fluidity of the solution in the lower part of the storage tank body and driving the bottom sediment to remix with the solution, maintaining the balance of the concentration of the admixture solution, maintaining good performance. And under the action of the protection tank body, the circulation assembly is protected. When the admixture solution is extracted and conveyed, a stable temperature is maintained, preventing the admixture from deteriorating under the influence of external factors during the conveying process, and the flow between the same solutions effectively reduces the influence of external factors on the properties of the admixture.

[0019] Further, as a preference, the circulation assembly includes:

[0020] A plurality of one-way nozzles, annularly distributed and fixed at the bottom of the storage tank body, and the one-way nozzles are located between the central stirring device and the outer ring stirring device;

[0021] An annular pipeline, arranged at the bottom of the storage tank body and connecting a plurality of one-way nozzles;

[0022] A plurality of water pumps, corresponding to the one-way nozzles and fixed inside the protection tank body, and connected to the annular pipeline through pipelines;

[0023] A plurality of extraction ports, corresponding to the water pumps and fixed on the side of the storage tank body and located at one-third of the height of the storage tank body, and connected to the water pumps through pipelines.

[0024] That is to say, when the storage amount of the admixture inside the storage tank exceeds one-third of the height of the storage tank, under the rotational action of the central stirring device and the outer ring stirring device at this time, the admixture solution inside the storage tank is stirred. At the same time, the solution inside the storage tank is extracted from the side of the storage tank through the extraction port, pressurized and transported by the water pump, collected through the annular pipeline, dispersed to each one-way nozzle, and sprayed out from the one-way nozzle, that is, sprayed upward from the bottom of the storage tank. Under the guidance of the adjustment and mixing device, it flows upward from the bottom of the storage tank and around the one-way nozzle, promoting the fluidity of the admixture solution inside the storage tank and effectively preventing the precipitation and accumulation of the admixture. When the storage amount of the admixture inside the storage tank is lower than one-third of the height of the storage tank, at this time, the circulation component is difficult to effectively circulate the admixture solution inside the storage tank, and only the central stirring device, the outer ring stirring device and the adjustment and mixing device need to rotate inside the storage tank to fully stir the admixture solution.

[0025] Further, as a preference, the central stirring device includes:

[0026] A plugging component, arranged at the inner center of the storage tank and corresponding to the discharge port;

[0027] A central rotating shaft, arranged on the central axis of the storage tank, with the top rotatably connected to the fixed top cover and the bottom fixedly connected to the plugging component;

[0028] A first motor, arranged above the fixed top cover and fixedly connected to the central rotating shaft;

[0029] A telescopic shaft section, connecting the fixed top cover and the first motor;

[0030] Stirring blades, with multiple linearly distributed, arranged inside the storage tank and fixed on the central rotating shaft.

[0031] That is to say, when the storage tank stores the admixture solution without being used, the telescopic shaft section contracts to drive the first motor and the central rotating shaft to move downward, and then the discharge port is plugged through the plugging component. Then, the first motor drives the central rotating shaft to rotate, and then drives the plugging component and the stirring blades to rotate in the middle of the storage tank. And during the rotation of the plugging component, the groove of the discharge port is effectively cleaned to prevent partial precipitation from accumulating at the discharge port and causing blockage when the admixture is transported through the discharge pipe. When it is necessary to use the admixture solution inside the storage tank, the telescopic shaft section extends to drive the first motor and the central rotating shaft to move upward, and then the plugging component disengages from the discharge port. Then, the discharge pipe is opened to transport the admixture solution inside the storage tank. And when transporting the admixture solution, the first motor can drive the central rotating shaft to rotate to carry out continuous stirring work to maintain the uniformity of the admixture solution inside the storage tank.

[0032] Further, as a preference, the plugging assembly includes:

[0033] A plugging sphere, fixed at the bottom of the central rotating shaft and corresponding to the top of the discharge pipe;

[0034] Scrapers, multiple annularly distributed, fixed around the plugging sphere, and the scrapers are in contact with the discharge port.

[0035] That is to say, when the plugging assembly plugs the discharge port, the plugging sphere is in contact with the top of the discharge pipe, and the scrapers are in contact with the concave surface of the discharge port. Driven by the central rotating shaft, the plugging sphere rotates on the top of the discharge pipe. While plugging the discharge pipe, it drives the scrapers to move the precipitate at the discharge port and remix it into the admixture solution, effectively preventing the accumulation of the precipitate generated by the admixture at the discharge port; when the plugging assembly disengages from the discharge port and the discharge pipe conveys the admixture inside the storage tank, at this time, driven by the central rotating shaft, the plugging sphere drives the scrapers to rotate above the discharge port, promoting the liquid flow at the discharge port. During the conveying process, the fluidity of the solution inside the storage tank is maintained, and the precipitation of the admixture solution from entering the discharge pipe is prevented.

[0036] Further, as a preference, the outer ring stirring device includes:

[0037] A second motor, fixed on the top of the fixed top cover, and the shaft of the second motor is arranged downward and passes through the fixed top cover;

[0038] A driving gear, fixedly connected to the shaft of the second motor;

[0039] A rotating gear ring, arranged inside the storage tank, with the inner ring meshing with the driving gear, and a slideway is provided in the middle of the outer ring;

[0040] Positioning members, multiple annularly distributed, fixed on the inner wall of the storage tank, and the rotating gear ring is rotatably connected to the positioning members through the slideway;

[0041] Stirring blades, multiple annularly distributed, fixed at the bottom of the rotating gear ring, and the outer sides of the stirring blades are rotatably connected to the inner wall of the storage tank.

[0042] That is to say, under the restriction of the positioning members, the rotating gear ring and the stirring blades can be rotatably arranged inside the storage tank. Driven by the second motor, the driving gear drives the rotating gear ring to rotate on the positioning members, and then drives the stirring blades to rotate on one side of the storage tank close to the inner wall, effectively preventing the accumulation of the precipitate of the admixture solution on the inner wall inside the storage tank, and cooperating with the central stirring device and the regulating and mixing device to fully stir the admixture solution inside the storage tank, preventing the precipitation and accumulation of the admixture solution.

[0043] Further, preferably, the adjustment and mixing device includes:

[0044] An adjustment component, arranged inside the storage tank body and corresponding to the one-way nozzle;

[0045] A diversion component, fixed on the top of the adjustment component;

[0046] A rotating inner shaft, with its bottom fixedly connected to the center of the adjustment component and its top connected to the control device;

[0047] A rotating outer shaft, rotatably arranged outside the rotating inner shaft, and the lower part of the rotating outer shaft is connected to the diversion component and its top is connected to the control device;

[0048] A connecting shaft body, arranged outside the rotating inner shaft and slidably connected to the inner wall of the rotating outer shaft, and the bottom of the connecting shaft body is connected to the adjustment component;

[0049] Mixing blades, a plurality of which are linearly distributed and fixed on the rotating outer shaft.

[0050] That is to say, under the action of the control device, the adjustment component and the diversion component are driven to move up and down by rotating the inner shaft and the outer shaft at the same time. When the bottom of the adjustment component approaches the one-way nozzle, the pressurized solution sprays out from the one-way nozzle. Under the action of the adjustment component, the solution disperses from the center of the bottom of the adjustment component to the surroundings, and then part of the solution flows upward along the side of the adjustment component to mix the admixture solution inside the storage tank body. When the adjustment component gradually moves away from the one-way nozzle, that is, the position where the solution sprays and disperses changes gradually inside the storage tank body. With the mutual flow between the solutions, the solution inside the storage tank body is promoted to maintain fluidity, effectively preventing the precipitation and accumulation of the admixture solution. And under the action of the control device, the rotating outer shaft can be driven to drive the mixing blades to rotate to assist the solution flow and mixing. Under the action of the adjustment component, the diversion component can be driven to expand or adjust the angle to guide and disperse the solution sprayed from the bottom, effectively increasing the mixing effect of the solution. It should be noted that the control device can control the up and down movement adjustment or rotation of the rotating outer shaft and the rotating inner shaft at the same time, or can separately control the up and down movement adjustment or rotation of the rotating outer shaft or the rotating inner shaft.

[0051] Further, preferably, the adjustment component includes:

[0052] A guiding bottom plate, arranged above the one-way nozzle, and the center of the top of the guiding bottom plate is fixedly connected to the bottom of the rotating inner shaft;

[0053] Moving tracks, a plurality of which are annularly distributed and fixed on the top of the guiding bottom plate;

[0054] The rotating disc is arranged at the top of the moving track and is provided with an adjusting arc corresponding to the moving track;

[0055] Multiple moving parts are annularly distributed and are slidably arranged on the moving track and the adjusting arc;

[0056] The connecting piece is fixed at the center of the rotating disc and is rotatably connected to the rotating inner shaft, and the top of the connecting piece is connected to the bottom of the connecting shaft body.

[0057] That is to say, under the action of the control device, the rotating inner shaft is fixed, and then the bottom plate and the moving track are guided to be in a fixed state. Then, the connecting shaft body is driven to rotate by the rotating outer shaft, and then the connecting shaft body drives the connecting piece to rotate. The rotating disc is driven to rotate by the connecting piece to adjust the position of the moving part. When the rotating disc rotates forward under the drive of the rotating outer shaft, the moving part moves outward on the moving track under the restriction of the adjusting arc; on the contrary, when the rotating disc rotates reversely under the drive of the rotating outer shaft, the moving part moves toward the center on the moving track under the restriction of the adjusting arc.

[0058] Further, as a preference, the flow guiding assembly includes:

[0059] Multiple fixing parts are annularly distributed and are fixed on the top of the moving part;

[0060] The flow guiding panel is correspondingly arranged with the fixing part and is rotatably connected to the fixing part. Multiple said flow guiding panels are combined into a complete ring;

[0061] The positioning ring is arranged at the lower part of the rotating outer shaft, and the rotating outer shaft is rotatably connected to the positioning ring;

[0062] The connecting rod is correspondingly arranged with the flow guiding panel, and both ends of the connecting rod are respectively hinged to the outside of the positioning ring and the top of the flow guiding panel.

[0063] That is to say, when the rotating disk rotates forward driven by the rotating outer shaft, under the restriction of the adjusting arc track, the moving part moves outward on the moving track. At the same time, the diversion panel is driven outward by the fixing part, so that the diversion panels are separated from each other. And at this time, under the action of the connecting rod, the positioning ring drives the rotating outer shaft to move downward on the connecting shaft body. Under the action of the diversion panel and the guiding bottom plate, the solution ejected from the one-way nozzle disperses around and flows upward from the outside of the guiding bottom plate, the interval between the diversion panels and the outside of the diversion panels, promoting the flow mixing of the admixture solution inside the storage tank. And the control device can drive the positioning ring to move upward, and then drive the diversion panel to rotate on the fixing part through the connecting rod to adjust the inclination angle of the diversion panel, guiding the upward flow direction of the solution. And during the continuous upward movement of the rotating outer shaft, the connecting shaft body can be driven to disengage from the connecting part. At this time, the rotating outer shaft and the rotating inner shaft can rotate independently. The rotating outer shaft drives the mixing blades to rotate, and the rotating inner shaft drives the adjusting component and the diversion component to rotate, fully mixing and stirring the admixture solution inside the storage tank. On the contrary, when the adjusting component and the diversion component are reset, first drive the rotating outer shaft to move downward through the control device until the diversion panel is restored to the horizontal state through the connecting rod. At this time, the connecting shaft body is connected to the connecting part, and then drive the rotating disk to rotate reversely by the rotating outer shaft. The fixing part drives the diversion panel to move back to the center under the drive of the moving part. And under the action of the connecting rod, drive the rotating outer shaft to move upward and reset on the connecting shaft body through the positioning ring.

[0064] Further, as a preference, the control device includes:

[0065] The lifting inner ring is arranged between multiple rotating inner shafts, connected to the rotating inner shafts, and the rotating inner shafts are rotationally connected to the lifting inner ring;

[0066] The lifting outer ring is arranged between multiple rotating outer shafts, located below the lifting inner ring. The lifting outer ring is connected to the rotating outer shafts, and the rotating outer shafts are rotationally connected to the lifting outer ring;

[0067] The inner telescopic shafts are annularly distributed with multiple ones, fixedly connecting the lifting inner ring and the fixed top cover;

[0068] The outer telescopic shafts are annularly distributed with multiple ones, fixedly connecting the lifting outer ring and the fixed top cover, and the outer telescopic shafts and the inner telescopic shafts can be controlled separately or synchronously.

[0069] That is to say, under the action of the inner telescopic shaft, the lifting inner ring drives the rotating inner shaft to move up and down. Under the action of the outer telescopic shaft, the lifting outer ring drives the rotating outer shaft to move up and down. The inner telescopic shaft is actively controlled, and the outer telescopic shaft can be actively controlled or can be telescoped under the drive of an external force. Under the control of the inner telescopic shaft, the position of the adjusting assembly inside the storage tank is adjusted through the rotating inner shaft. Under the action of the outer telescopic shaft, when adjusting the diversion panel in the diversion assembly, the outer telescopic shaft is passively telescoped and adjusted. When adjusting the inclination angle of the diversion panel, the outer telescopic shaft actively telescopes to adjust the inclination angle of the diversion panel.

[0070] Further, as a preference, a plurality of driving motors are respectively arranged on the lifting inner ring and the lifting outer ring, and the driving motors are respectively fixedly connected to the rotating inner shaft and the rotating outer shaft. That is to say, driven by the driving motors, the rotating inner shaft and the rotating outer shaft are driven to rotate, thereby driving the guiding bottom plate and the diversion panel to rotate above the one-way nozzle, and driving the mixing blades to rotate inside the admixture solution, promoting the flow and mixing of the admixture solution, and effectively preventing the precipitation and accumulation of the admixture.

[0071] Compared with the prior art, the beneficial effects of the present invention are:

[0072] Through the setting of the central stirring device and the outer ring stirring device of the present invention, the admixture inside the tank is stirred, effectively preventing the precipitation of the admixture at the center and the inner wall inside the tank; through the setting of the circulation assembly, the admixture inside the tank is extracted and then injected into the tank. Through the flow of the admixture when it enters the tank, the admixture inside the tank is in a flowing state, maintaining the fluidity of the admixture and effectively reducing the generation of precipitation; through the setting of the adjusting and mixing device, the admixture injected into the tank is guided to flow to various parts of the tank, making the admixture inside the tank in an active state, and through dynamic adjustment by the control device, effectively preventing the precipitation and accumulation of the admixture in the tank.

Detailed implementation manners

[0082] Please refer to Figures 1 to 8 , in an embodiment of the present invention, a concrete admixture storage tank for preventing sediment accumulation includes:

[0083] A fixed frame 1 for carrying the concrete admixture storage tank;

[0084] A storage tank 2 fixed on the fixed frame 1;

[0085] A central stirring device 3 arranged in the middle of the storage tank 2;

[0086] An outer ring stirring device 4 arranged inside the storage tank 2 and rotatably connected to the inner wall of the storage tank 2;

[0087] Adjustment mixing devices 5 are annularly distributed in plurality, arranged inside the storage tank 2 and located between the central stirring device 3 and the outer ring stirring device 4;

[0088] A control device 6 fixed on the top of the storage tank 2 and connected to the top of the adjustment mixing device 5.

[0089] In this embodiment, the storage tank 2 includes:

[0090] A protective tank body 21, fixed on the fixing frame 1;

[0091] A storage tank body 22, coaxially arranged with the protective tank body 21 and fixed inside the protective tank body 21;

[0092] A circulation assembly 23, arranged between the bottom and the side of the protective tank body 21 and the storage tank body 22;

[0093] A discharge port 24, in a concave shape, arranged at the center of the bottom of the storage tank body 22;

[0094] A discharge pipe 25, one end of which is fixed to the bottom of the discharge port 24 and the other end communicates with the center of the bottom of the protective tank body 21;

[0095] A fixed top cover 26, fixed on the tops of the protective tank body 21 and the storage tank body 22;

[0096] A feed port 27, fixed on the fixed top cover 26 and located at the top of the storage tank body 22.

[0097] That is to say, the concrete admixture is injected into the storage tank body 22 through the feed port 27 for storage. Under the action of the central stirring device 3 and the outer ring stirring device 4, the admixture inside the storage tank body 22 is stirred, effectively reducing the probability of sedimentation of the admixture inside the storage tank body 22. And the circulation assembly 23 extracts the admixture solution inside the storage tank body 22 and then conveys it into the storage tank body 22 from the bottom. With the cooperation of the regulating and mixing device 5, the flow direction of the solution is dispersed, promoting the fluidity of the solution at the lower part of the storage tank body 22 and driving the bottom sediment to remix with the solution, maintaining the concentration balance of the admixture solution, maintaining good performance. And under the action of the protective tank body 21, the circulation assembly 23 is protected. When extracting and conveying the admixture solution, a stable temperature is maintained, preventing the admixture from deteriorating under the influence of external factors during the conveying process, and the flow between the same solutions effectively reduces the influence of external factors on the properties of the admixture.

[0098] In this embodiment, the circulation assembly 23 includes:

[0099] A plurality of one-way nozzles 231, annularly distributed and fixed at the bottom of the storage tank body 22, and the one-way nozzles 231 are located between the central stirring device 3 and the outer ring stirring device 4;

[0100] An annular pipeline 232, arranged at the bottom of the storage tank body 22 and connecting a plurality of one-way nozzles 231;

[0101] There are multiple water pumps 233, which are correspondingly arranged with the one-way nozzles 231, fixed inside the protective tank body 21, and are connected to the annular pipeline 232 through pipelines;

[0102] There are multiple extraction ports 234, which are correspondingly arranged with the water pumps 233, fixed on the side of the storage tank body 22, and are located at one-third of the height of the storage tank body 22, and are connected to the water pumps 233 through pipelines.

[0103] That is to say, when the storage volume of the admixture inside the storage tank body 22 exceeds one-third of the height of the storage tank body 22, at this time, under the rotation of the central stirring device 3 and the outer ring stirring device 4, the admixture solution inside the storage tank body 22 is stirred. At the same time, the solution inside the storage tank body 22 is extracted from the side of the storage tank body 22 through the extraction port 234, pressurized and transported by the water pump 233, gathered through the annular pipeline 232, and dispersed to each one-way nozzle 231, and sprayed out from the one-way nozzle 231, that is, sprayed upward from the bottom of the storage tank body 22. Under the guidance of the regulating and mixing device 5, it flows upward from the bottom of the storage tank body 22 and around the one-way nozzle 231, promoting the fluidity of the admixture solution inside the storage tank body 22 and effectively preventing the precipitation and accumulation of the admixture; when the storage volume of the admixture inside the storage tank body 22 is lower than one-third of the height of the storage tank body 22, at this time, it is difficult for the circulation assembly 23 to effectively circulate the admixture solution inside the storage tank body 22, and only need to rotate the central stirring device 3, the outer ring stirring device 4 and the regulating and mixing device 5 inside the storage tank body 22 to fully stir the admixture solution.

[0104] In this embodiment, the central stirring device 3 includes:

[0105] The plugging assembly 31 is arranged at the center inside the storage tank body 22 and corresponds to the discharge port 24;

[0106] The central rotating shaft 32 is arranged on the central axis of the storage tank body 22, the top is rotationally connected to the fixed top cover 26, and the bottom is fixedly connected to the plugging assembly 31;

[0107] The first motor 33 is arranged above the fixed top cover 26 and is fixedly connected to the central rotating shaft 32;

[0108] The telescopic shaft section 34 connects the fixed top cover 26 and the first motor 33;

[0109] There are multiple stirring blades 35 linearly distributed, arranged inside the storage tank body 22 and fixed on the central rotating shaft 32.

[0110] That is to say, when the storage tank body 22 stores the admixture solution without using it, the telescopic shaft section 34 contracts to drive the first motor 33 and the central rotating shaft 32 to move downward, and then the blocking component 31 blocks the discharge port 24. Then, the first motor 33 drives the central rotating shaft 32 to rotate, thereby driving the blocking component 31 and the stirring blades 35 to rotate in the middle of the storage tank body 22. And during the rotation of the blocking component 31, the groove of the discharge port 24 is effectively cleaned to prevent partial precipitation from accumulating at the discharge port 24 and causing blockage when the admixture is conveyed through the discharge pipe 25; when the admixture solution inside the storage tank body 22 needs to be used, the telescopic shaft section 34 extends to drive the first motor 33 and the central rotating shaft 32 to move upward, and then the blocking component 31 disengages from the discharge port 24. Then, the discharge pipe 25 is opened to convey the admixture solution inside the storage tank body 22. And when conveying the admixture solution, the first motor 33 can drive the central rotating shaft 32 to rotate to perform continuous stirring work to maintain the uniformity of the admixture solution inside the storage tank body 22.

[0111] In this embodiment, the blocking component 31 includes:

[0112] A blocking sphere 311, fixed to the bottom of the central rotating shaft 32 and corresponding to the top of the discharge pipe 25;

[0113] Scraping plates 312, a plurality of which are annularly distributed and fixed around the blocking sphere 311, and the scraping plates 312 are in contact with the discharge port 24.

[0114] That is to say, when the blocking component 31 blocks the discharge port 24, the blocking sphere 311 is in contact with the top of the discharge pipe 25, and the scraping plates 312 are in contact with the concave surface of the discharge port 24. Driven by the central rotating shaft 32, the blocking sphere 311 rotates on the top of the discharge pipe 25. While blocking the discharge pipe 25, it drives the scraping plates 312 to move the precipitation at the discharge port 24 and remix it into the admixture solution, effectively preventing the precipitation generated by the admixture from accumulating at the discharge port 24; when the blocking component 31 disengages from the discharge port 24 and the discharge pipe 25 conveys the admixture inside the storage tank body 22, at this time, driven by the central rotating shaft 32, the blocking sphere 311 drives the scraping plates 312 to rotate above the discharge port 24 to promote the liquid flow at the discharge port 24. During the conveying process, the fluidity of the solution inside the storage tank body 22 is maintained to prevent the admixture solution from generating precipitation and entering the discharge pipe 25.

[0115] In this embodiment, the outer ring stirring device 4 includes:

[0116] A second motor 41, fixed to the top of the fixed top cover 26, and the shaft body of the second motor 41 is arranged downward and passes through the fixed top cover 26;

[0117] The driving gear 42 is fixedly connected to the shaft body of the second motor 41;

[0118] The rotating toothed ring 43 is arranged in the storage tank body 22, and the inner ring meshes with the driving gear 42, and a slideway is arranged in the middle of the outer ring;

[0119] A plurality of positioning members 44 are annularly distributed and fixed on the inner wall of the storage tank body 22, and the rotating toothed ring 43 is rotatably connected to the positioning members 44 through the slideway;

[0120] A plurality of stirring blades 45 are annularly distributed and fixed to the bottom of the rotating toothed ring 43, and the outer side of the stirring blade 45 is rotatably connected to the inner wall of the storage tank body 22.

[0121] That is to say, under the limitation of the positioning members 44, the rotating toothed ring 43 and the stirring blades 45 can be rotatably arranged inside the storage tank body 22. Driven by the second motor 41, the driving gear 42 drives the rotating toothed ring 43 to rotate on the positioning members 44, and then drives the stirring blades 45 to rotate on one side close to the inner wall of the storage tank body 22, effectively preventing the precipitation and accumulation of the admixture solution inside the storage tank body 22 on the inner wall, and cooperating with the central stirring device 3 and the mixing and adjusting device 5 to fully stir the admixture solution inside the storage tank body 22 to prevent the precipitation and accumulation of the admixture solution.

[0122] In this embodiment, the mixing and adjusting device 5 includes:

[0123] The adjusting assembly 51 is arranged in the storage tank body 22 and corresponds to the one-way nozzle 231;

[0124] The diversion assembly 52 is fixed on the top of the adjusting assembly 51;

[0125] The rotating inner shaft 53 is fixedly connected to the center of the bottom of the adjusting assembly 51 at the bottom and is connected to the control device 6 at the top;

[0126] The rotating outer shaft 54 is rotatably arranged on the outside of the rotating inner shaft 53, and the lower part of the rotating outer shaft 54 is connected to the diversion assembly 52 and the top is connected to the control device 6;

[0127] The connecting shaft body 55 is arranged on the outside of the rotating inner shaft 53 and is slidably connected to the inner wall of the rotating outer shaft 54, and the bottom of the connecting shaft body 55 is connected to the adjusting assembly 51;

[0128] A plurality of mixing blades 56 are linearly distributed and fixed on the rotating outer shaft 54.

[0129] That is to say, under the action of the control device 6, the inner shaft 53 and the rotating outer shaft 54 are rotated through the shaft to drive the adjusting assembly 51 and the diversion assembly 52 to move up and down for adjustment at the same time. When the bottom of the adjusting assembly 51 approaches the one-way nozzle 231, the pressurized solution is ejected from the one-way nozzle 231. Under the action of the adjusting assembly 51, the solution disperses from the center of the bottom of the adjusting assembly 51 to the surroundings, and then part of the solution flows upward along the side of the adjusting assembly 51 to mix the admixture solution inside the storage tank 22. When the adjusting assembly 51 gradually moves away from the one-way nozzle 231, that is, the position where the ejected solution is dispersed gradually changes inside the storage tank 22. With the mutual flow between the solutions, the solution inside the storage tank 22 is promoted to maintain fluidity, effectively preventing the precipitation and accumulation of the admixture solution. And under the action of the control device 6, the mixing blade 56 can be driven to rotate by the rotating outer shaft 54 to assist the solution to flow and mix. Under the action of the adjusting assembly 51, the diversion assembly 52 can be driven to expand or adjust the angle to guide and disperse the solution ejected from the bottom, effectively increasing the mixing effect of the solution. It should be noted that the control device 6 can simultaneously control the rotating outer shaft 54 and the rotating inner shaft 53 to move up and down for adjustment or rotation, or can separately control the rotating outer shaft 54 or the rotating inner shaft 53 to move up and down for adjustment or rotation.

[0130] In this embodiment, the adjusting assembly 51 includes:

[0131] A guiding bottom plate 511 is arranged above the one-way nozzle 231, and the center of the top of the guiding bottom plate 511 is fixedly connected to the bottom of the rotating inner shaft 53;

[0132] A plurality of moving tracks 512 are annularly distributed and fixed on the top of the guiding bottom plate 511;

[0133] A rotating disk 513 is rotatably arranged on the top of the moving track 512, and an adjusting arc track 514 corresponding to the moving track 512 is arranged on the rotating disk 513;

[0134] A plurality of moving parts 515 are annularly distributed and slidably arranged on the moving track 512 and the adjusting arc track 514;

[0135] A connecting piece 516 is fixed at the center of the rotating disk 513 and is rotatably connected to the rotating inner shaft 53. The top of the connecting piece 516 is connected to the bottom of the connecting shaft body 55.

[0136] That is to say, under the action of the control device 6, the rotating inner shaft 53 is fixed, thereby guiding the bottom plate 511 and the moving track 512 to be in a fixed state. Then, the connecting shaft body 55 is driven to rotate by the rotating outer shaft 54. Further, the connecting shaft body 55 drives the connecting member 516 to rotate, and the rotating disc 513 is driven to rotate by the connecting member 516 to adjust the position of the moving member 515. When the rotating disc 513 rotates forward under the drive of the rotating outer shaft 54, the moving member 515 moves outward on the moving track 512 under the restriction of the adjusting arc 514; conversely, when the rotating disc 513 rotates reversely under the drive of the rotating outer shaft 54, the moving member 515 moves toward the center on the moving track 512 under the restriction of the adjusting arc 514.

[0137] In this embodiment, the flow guiding assembly 52 includes:

[0138] A plurality of fixing members 521 are annularly distributed and fixed on the top of the moving member 515;

[0139] Flow guiding panels 522 are correspondingly arranged with the fixing members 521 and are rotatably connected to the fixing members 521. The plurality of flow guiding panels 522 are combined into a complete ring;

[0140] A positioning ring 523 is arranged at the lower part of the rotating outer shaft 54, and the rotating outer shaft 54 is rotatably connected to the positioning ring 523;

[0141] Link rods 524 are correspondingly arranged with the flow guiding panels 522. The two ends of each link rod 524 are respectively hinged to the outside of the positioning ring 523 and the top of the flow guiding panel 522.

[0142] That is to say, when the rotating disk 513 rotates forward driven by the rotating outer shaft 54, the moving part 515 moves outward on the moving track 512 under the restriction of the adjusting arc 514, and at the same time drives the diversion panel 522 to move outward through the fixing part 521, so that the plurality of diversion panels 522 are separated from each other. And at this time, under the action of the connecting rod 524, the positioning ring 523 drives the rotating outer shaft 54 to move downward on the connecting shaft body 55. Under the action of the diversion panel 522 and the guiding bottom plate 511, the solution ejected from the one-way nozzle 231 flows upward while dispersing around, from the outside of the guiding bottom plate 511, the interval between the diversion panels 522 and the outside of the diversion panels 522, promoting the flow and mixing of the admixture solution inside the storage tank body 22. And the control device 6 can drive the positioning ring 523 to move upward, and then drive the diversion panel 522 to rotate on the fixing part 521 through the connecting rod 524 to adjust the inclination angle of the diversion panel 522, guiding the upward flow direction of the solution. And during the continuous upward movement of the rotating outer shaft 54, the connecting shaft body 55 can be driven to disengage from the connecting part 516. At this time, the rotating outer shaft 54 and the rotating inner shaft 53 can rotate independently. The rotating outer shaft 54 drives the mixing blades 56 to rotate, and the rotating inner shaft 53 drives the adjusting assembly 51 and the diversion assembly 52 to rotate, fully mixing and stirring the admixture solution inside the storage tank body 22. On the contrary, when the adjusting assembly 51 and the diversion assembly 52 are reset, first drive the rotating outer shaft 54 to move downward through the control device 6 until the diversion panel 522 is restored to the horizontal state through the connecting rod 524. At this time, the connecting shaft body 55 is connected to the connecting part 516, and then drive the rotating disk 513 to rotate reversely by the rotating outer shaft 54. The fixing part 521 drives the diversion panel 522 to move back to the center under the drive of the moving part 515, and under the action of the connecting rod 524, drives the rotating outer shaft 54 to move upward and reset on the connecting shaft body 55 through the positioning ring 523.

[0143] In this embodiment, the control device 6 includes:

[0144] A lifting inner ring 61, arranged between the plurality of rotating inner shafts 53, connected to the rotating inner shafts 53, and the rotating inner shafts 53 are rotatably connected to the lifting inner ring 61;

[0145] A lifting outer ring 62, arranged between the plurality of rotating outer shafts 54, located below the lifting inner ring 61, the lifting outer ring 62 is connected to the rotating outer shafts 54, and the rotating outer shafts 54 are rotatably connected to the lifting outer ring 62;

[0146] Inner telescopic shafts 63, a plurality of which are annularly distributed, fixedly connecting the lifting inner ring 61 and the fixed top cover 26;

[0147] There are multiple outer telescopic shafts 64 distributed in a ring shape, which are fixedly connected to the lifting outer ring 62 and the fixed top cover 26, and the outer telescopic shafts 64 and the inner telescopic shafts 63 can be controlled separately or synchronously.

[0148] That is to say, under the action of the inner telescopic shaft 63, the rotating inner shaft 53 is driven by the lifting inner ring 61 to move up and down. Under the action of the outer telescopic shaft 64, the rotating outer shaft 54 is driven by the lifting outer ring 62 to move up and down. The inner telescopic shaft 63 is actively controlled, and the outer telescopic shaft 64 can be actively controlled or can be telescoped under the drive of an external force. Under the control of the inner telescopic shaft 63, the position of the adjusting assembly 51 inside the storage tank 22 is adjusted through the rotating inner shaft 53. Under the action of the outer telescopic shaft 64, when adjusting the diversion panel 522 in the diversion assembly 52, the outer telescopic shaft 64 is telescopically adjusted passively. When adjusting the inclination angle of the diversion panel 522, the outer telescopic shaft 64 is actively telescoped to adjust the inclination angle of the diversion panel 522.

[0149] In this embodiment, a plurality of driving motors are respectively provided on the lifting inner ring 61 and the lifting outer ring 62, and the driving motors are respectively fixedly connected to the rotating inner shaft 53 and the rotating outer shaft 54. That is to say, driven by the driving motors, the rotating inner shaft 53 and the rotating outer shaft 54 are driven to rotate, thereby driving the guiding bottom plate 511 and the diversion panel 522 to rotate above the one-way nozzle 231, and driving the mixing blades 56 to rotate inside the admixture solution, promoting the flow and mixing of the admixture solution, and effectively preventing the precipitation and accumulation of the admixture.

[0150] In specific implementation, first, the discharge port 24 is blocked by the blocking component 31, and then the admixture solution is injected into the storage tank body 22 through the feed port 27 for storage. When in use, the telescopic shaft section 34 extends to drive the first motor 33 and the central rotating shaft 32 to move upward, so that the blocking component 31 disengages from the discharge port 24, and then the discharge pipe 25 is opened to convey the admixture solution inside the storage tank body 22. During storage, the central stirring device 3, the outer ring stirring device 4, and the adjustment mixing device 5 are used to mix and stir the admixture solution inside the storage tank body 22 to prevent precipitation and accumulation of the admixture solution. When the storage amount of the admixture solution inside the storage tank body 22 exceeds one-third of the volume of the storage tank body 22, at this time, while using the central stirring device 3, the outer ring stirring device 4, and the adjustment mixing device 5 for mixing and stirring, the solution inside the storage tank body 22 is extracted from the side of the storage tank body 22 through the extraction port 234 of the circulation component 23, pressurized and conveyed by the water pump 233, collected through the annular pipe 232, and dispersed to each one-way nozzle 231, and sprayed out from the one-way nozzle 231. Under the guidance of the adjustment mixing device 5, it flows upward from the bottom of the storage tank body 22 and around the one-way nozzle 231, promoting the fluidity of the admixture solution inside the storage tank body 22. And under the action of the control device 6, the dispersion position and flow direction of the sprayed solution are adjusted through the adjustment component 51 and the diversion component 52, effectively preventing the phenomenon of precipitation and accumulation of the admixture; when the storage amount of the admixture inside the storage tank body 22 is lower than one-third of the volume of the storage tank body 22, at this time, it is difficult for the circulation component 23 to effectively circulate the admixture solution inside the storage tank body 22, and only need to rotate the central stirring device 3, the outer ring stirring device 4, and the adjustment mixing device 5 inside the storage tank body 22 to fully stir the admixture solution.

[0151] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
