Specific embodiments

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1:

[0021] As shown in the accompanying drawings of the specification Figures 1-8 This application provides a fluid material anti - adhesion stirring tank. The stirring tank includes a tank body 1. A top cover 11 is installed at the top of the tank body 1. An installation frame is arranged at the bottom of the tank body 1. A stirring shaft 12 is rotatably arranged in the middle part of the top cover 11. The bottom of the stirring shaft 12 extends to a support seat on the inner wall of the tank body 1. A stirrer 2 is arranged on the outer surface of the stirring shaft 12. The top of the stirring shaft 12 is connected to the output end of a power device above the top cover 11. The power device can be a motor device. Baffles 3 are evenly arranged around the stirring shaft 12 in the middle area of the inner wall of the tank body 1; The cross - section of the baffle 3 is triangular, and the inside of the baffle 3 is hollow to form a flushing cavity 33. The outer surface of the baffle 3 is covered with a protective layer 31, which can be a rubber surface layer or a metal coating in the prior art to avoid the wear of the baffle 3 due to the stirring action; Flushing holes 32 are arranged at both sides of the baffle 3 close to the inner wall of the tank body 1. The flushing holes 32 pass through the protective layer 31 and communicate with the inside of the flushing cavity 33. The water filling port 331 at the top of the baffle 3 extends to the upper surface of the top cover 11; The flushing holes 32 in this application are conical, with a smaller outer opening, so that the fluid material outside is difficult to penetrate inward. And according to needs, existing self - cleaning nozzles can be arranged inside the flushing holes 32, with a piston structure driven by a spring. When the machine stops, the spray holes are automatically closed, and after starting, the cleaning liquid inside the flushing cavity 33 is sprayed out to dredge the opening of the flushing hole 32 and prevent the fluid material inside the tank body 1 from causing blockage at the opening of the flushing hole 32.

[0022] Specific working process: In industrial production, when different types of fluid materials need to be fully mixed, and the possible particle agglomeration substances and the like need to be dispersed and dissolved to improve the characteristics of the fluid materials, a stirring tank device will be used to fully stir the fluid materials; Specifically, different types of fluid substances to be processed are filled into the tank body 1 through the liquid inlet on the top cover 11. Subsequently, the liquid inlet is closed, and the power equipment is started to drive the stirring shaft 12 to rotate, thereby driving the stirrer 2 on the stirring shaft 12 to agitate the fluid substances flowing into the tank body 1. The fluid substances rotate around the stirring shaft 12 and are fully mixed during the rotation process. To improve the stirring effect on the fluid substances, in this application, vertical baffles 3 are arranged on the inner wall of the tank body 1, and the baffles 3 are annularly distributed around the middle stirring shaft 12 to realize the adjustment of the stirring condition of the fluid substances. Specifically, the tapered end of the baffle 3 points to the stirring shaft 12, and the parts near the inner walls of the two sides of the tank body 1 are inclined surfaces. In this way, as the stirrer 2 drives the fluid substances inside the tank body 1 to rotate and flow, due to the centrifugal force, the denser parts of the fluid substances, including possible particles, agglomerates, etc., will gradually be centrifugally deflected to the area near the inner wall of the tank body 1. The friction between this part of the fluid substances that continuously rotates in the area near the inner wall of the tank body 1 and the inner wall of the tank body 1 may cause damage to the inner wall of the tank body 1. And it is easy for this part of the fluid substances to be weakened by the stirring effect because they are far from the stirring shaft 12, and because they are in contact with the inner wall of the tank body 1 and are subject to frictional resistance, it is easy to cause the flow rate to slow down and accumulate in the area near the inner wall of the tank body 1, and adhere to the inner wall surface of the tank body 1. Therefore, by setting the baffle 3, when this part of the fluid substances rotates in the area near the inner wall of the tank body 1, they are intercepted by the baffle 3, and the state of gathering and continuously rotating in the outer area near the inner wall of the tank body 1 is destroyed, and they flow towards the direction close to the stirring shaft 12 under the guiding action of the inclined surfaces on both sides of the baffle 3, and participate in the intense agitation under the action of the stirrer 2 in the middle area, promoting the accelerated decomposition of this part of the agglomerated substances and dissolving them into the whole fluid substances, and also reducing the wear on the inner wall of the tank body 1. Moreover, the guiding action of the baffle 3 also promotes the horizontal fluidity of the fluid substances inside the tank body 1. By adjusting the flow direction and path of the fluid substances inside the tank body 1, it promotes the formation of a complex flow pattern of the fluid substances in the tank, such as a combination of axial flow and radial flow, so that the fluid substances inside the tank body 1 are fully mixed. And when the processed fluid substances are highly viscous, during the subsequent cleaning process, a dead zone where residual substances are likely to adhere and accumulate and are difficult to clean easily appears in the semi-surrounded area between the inclined surfaces on both sides of the baffle 3 and the inner wall of the tank body 1, causing inconvenience to the cleaning process. Therefore, in this application, a flushing chamber 33 is arranged inside the baffle 3. The control valve arranged at the water filling port 331 of the tubular structure at the top can be opened to connect it to the external cleaning liquid supply equipment, and cleaning liquid is filled into the flushing chamber 33. Cooperating with the cleaning liquid directly sent through the liquid inlet, the residual substances adhering to the inside of the tank body 1 are cleaned as the stirrer 2 rotates. The specific selection of the cleaning liquid can be made according to the material of the tank body 1 and the type of the processed fluid substance. For example, if the processed fluid substance is a water-soluble material, such as sugars, inorganic salts, water-based coatings, etc., a water-based cleaning liquid prepared based on water can be selected; when the processed fluid substance is an oil-soluble material, such as grease, lubricating oil, asphalt, etc., a solvent-based cleaning liquid, such as organic solvents, emulsifiers, etc., can be selected, or an alkaline solution can be used for cleaning by saponification reaction. The cleaning liquid ejected outward from the flushing holes 32 on both sides of the baffle 3 directly acts on the possible dead zone positions in the gaps between both sides of the baffle 3 and the inner wall of the tank body 1, so that this area is subjected to a targeted impact cleaning effect, accelerating the shedding of the fluid substance adhered to this area; the presence of the baffle 3 divides the middle area of the inner wall of the tank body 1 into multiple smaller smooth areas, avoiding the occurrence of large-area sheet adhesion; making the adhesion on the inner wall of the tank body 1 mainly small-piece sheet adhesion with a smaller area and a larger number. The contact surface between the small-piece sheet adhesion and the inner wall of the tank body 1 is smaller, and the adhesion bonding effect is smaller. Moreover, there are more bonding gaps between the edge parts of the sheet adhesion and the inner wall of the tank body 1, which is convenient for the agitated cleaning liquid to impact the bonding gaps and peel off the small-piece sheet adhesion from the inner wall of the tank body 1, improving the cleaning efficiency of the adhered material on the inner wall of the tank body 1. The cleaning liquid ejected from the flushing holes 32 pointing to the inner wall of the tank body 1 acts on the area of the inner wall of the tank body 1 located in the gap between the partition plates. And for the sheet-shaped adhesion substance extending to the surface of the baffle 3, the flushing holes 32 are located in the gap between the sheet-shaped adhesion substance and the inner wall of the tank body 1. The ejected cleaning liquid causes the sheet-shaped adhesion substance to be impacted from the inside to the outside and accelerate the peeling off; in cooperation with the action of the stirrer 2, it promotes the cleaning liquid to act more fully on each area of the inner wall of the tank body 1, realizes the full cleaning of the viscous substance adhered to the inner wall of the tank body 1, and ensures the normal use of the mixing tank.

[0023] Embodiment 2:

[0024] On the basis of Embodiment 1, the stirrer 2 includes a paddle stirrer 21 and an anchor stirrer 22. The paddle stirrer 21 is arranged in the middle part of the stirring shaft 12, and the anchor stirrer 22 is installed in the area of the stirring shaft 12 close to the bottom. The stirring shaft 12 is arranged in two sections. The paddle stirrer 21 and the anchor stirrer 22 respectively correspond to different sections of the stirring shaft 12, and a coupling 23 is arranged between the parts of the stirring shaft 12 corresponding to the paddle stirrer 21 and the anchor stirrer 22.

[0025] Specific working process: Based on the specific working process in the first embodiment, for fluid substances with strong viscosity, in order to improve the stirring effect on the fluid substances while reducing the adhesion of the fluid substances to the inner wall of the tank body 1, the present application adopts two stirrers 2. The stirrer 2 located at the center of the tank body 1 is a paddle stirrer 21, which can operate at a relatively high speed and adopts a paddle structure with inclined blades. In this way, while rotating, it promotes the fluid substances near the stirring shaft 12 to flow downward, and after the flow is blocked at the bottom, it flows upward along the area near the inner wall of the tank body 1 and is replenished to the upper area, realizing the circulating flow of the inner wall of the tank body 1 and promoting the exchange of fluid substances in the vertical and horizontal directions; An anchor stirrer 22 is arranged at the position of the stirring shaft 12 near the bottom area. The shape of the paddle of the anchor stirrer 22 is adapted to the arc-shaped bending part at the bottom of the tank body 1, and the paddle is close to the inner wall area at the bottom of the tank body 1. In this way, when the anchor stirrer 22 rotates, it can scrape and clean the fluid substances adhering to the inner wall of the bottom of the tank body 1 while agitating the fluid substances, preventing them from aggregating and depositing, so that the circulating flow of the fluid substances inside the tank body 1 can proceed normally; Because the applicable rotation speeds of the anchor stirrer 22 and the paddle stirrer 21 are different, the stirring shaft 12 can be set into a two-section type, and the anchor stirrer 22 and the paddle stirrer 21 correspond to different sections of the stirring shaft 12, and a coupling 23 is arranged between the two ends of the stirring shaft 12; as needed, driving motors can be respectively arranged at the top and bottom of the mixing tank to drive the corresponding stirring shaft 12 to work at an appropriate rotation speed; or the coupling 23 can be set as an electromagnetic coupling, which is controlled by an external controller and normally remains disconnected. The power device controls the paddle stirrer 21 to work at a relatively high rotation speed to agitate the fluid substances inside the tank body 1; after stirring for a period of time, the power device is controlled to reduce the rotation speed. At this time, the electromagnetic coupling 23 is controlled to keep the upper and lower two sections of the stirring shaft 12 rotating synchronously to clean the fluid substances that may aggregate and deposit in the bottom area of the mixing tank, avoiding the accumulation of the denser part of the fluid substances and the possible agglomerated particle part at the bottom of the mixing tank, resulting in insufficient mixing of the fluid substances.

[0026] Embodiment Three:

[0027] Based on the second embodiment, a circular limiting block 13 is arranged on the inner wall of the tank body 1. There are various possible implementation schemes for the selection of the limiting block 13. The cross-section of the limiting block 13 can be a structure similar to a trapezoid, as shown in the attached Figure 2 description. The top surface is a horizontal plane to support the upper baffle 3, and the bottom surface is an inclined plane to guide the fluid substances flowing upward from the lower side; The cross-section of the limiting block 13 can also be an isosceles triangle, with both the upper and lower surfaces being inclined planes, which facilitates the smooth downward flow of the fluid substance along the upper inclined surface of the limiting block 13 and through the limiting block 13 during the discharging process, reducing the obstruction of the limiting block 13 to the downward-flowing fluid substance and making the discharging process smoother; the user can select the type of the limiting block 13 according to needs; And the limiting block 13 is located in the gap area between the paddle stirrer 21 and the anchor stirrer 22 in the vertical direction; stirring blocks 131 are uniformly arranged on the horizontal bottom surface of the limiting block 13, the cross-section of the stirring blocks 131 is triangular, and they are annularly distributed around the stirring shaft 12; a pushing plate 221 is arranged at the top of the paddle of the anchor stirrer 22, the pushing plate 221 is inclined, and notches 132 are arranged at positions corresponding to both sides of the baffle 3 on the limiting block 13, and the notches 132 correspond to the areas where dead zones are likely to appear between the two side surfaces of the baffle 3 and the inner wall of the tank body 1 in the vertical direction.

[0028] Specific working process: On the basis of the specific working process in the second embodiment, due to gravity and centrifugal force, the denser part of the fluid substance and the possible agglomerated and particulate parts are likely to gather in the parts close to the inner wall of the tank body 1 during the stirring process, especially in the area close to the inner wall at the bottom of the tank body 1. These areas are less affected by the stirrer 2, and due to the frictional effect of the inner wall of the tank body 1, the fluid substance in these areas has poor fluidity, and it is easy to have insufficient stirring and excessive aggregation of the fluid substance, resulting in a situation of accumulation and adhesion; When the anchor stirrer 22 rotates, it will cause the fluid substance in the area close to the inner wall at the bottom of the tank body 1 to break away and flow upward under the action of the internal circulation flow of the fluid substance in the tank body 1. By setting the annular limiting block 13, the part of the fluid substance flowing upward at the bottom of the tank body 1 that flows close to the inner wall of the tank body 1 can be intercepted, so that the part close to the middle and fully stirred and mixed in the fluid substance at the bottom of the tank body 1 can flow upward smoothly, while the part that flows along the inner wall and is not fully stirred and mixed is intercepted and left at the bottom of the tank body 1. Because the anchor stirrer 22 acts intensively on the position close to the inner wall area of the tank body 1, the part of the fluid substance that is intercepted and left will be continuously agitated by the anchor stirrer 22 and be fully mixed evenly; For this part of the fluid substance with blocked flow, it will gather in the gap area between the end of the paddle of the anchor stirrer 22 and the limiting block 13. As the paddle rotates, this part of the flowing substance continuously rotates along the lower surface of the limiting block 13 and is continuously impacted by the uniformly distributed stirring blocks 131 on the lower surface of the limiting block 13, so that the possible agglomerates, particles, etc. in the fluid substance flowing close to the inner wall are dispersed into the fluid substance under the continuous impact, thus making the fluid substance more evenly mixed; And because the limiting block 13 is provided with a notch 132, as the pushing plate 221 on the blade of the anchor agitator 22 coincides with the notch 132, part of the fluid substance is pushed by the pushing plate 221 and forms an impact flow that impacts the area between both sides of the baffle 3 and the inner wall of the tank body 1 through the notch 132. The dead zones where fluid substances may accumulate in these areas are vertically impacted by the upward flowing impact flow through the notch 132, prompting the fluid substances that may accumulate here to diffuse out under the vertical impact, thereby reducing the situation where fluid substances accumulate and adhere to the surfaces on both sides of the baffle 3, and further reducing the adhesion situation that appears on the inner wall of the tank body 1 after discharging the fluid substances; Because the part of the fluid substance flowing inside the tank body 1 near the bottom inner wall has an upward flowing tendency, especially for the part near the lower side of the limiting block 13, due to the pushing action of the pushing plate 221 on the blade of the anchor agitator 22, the main motion state of the fluid substance passing through the notch 132 is vertical flow, thereby reducing the adhesion situation of the fluid substance on the inner wall of the notch 132; and during the cleaning process, the cleaning liquid fills the bottom area inside the tank body 1. As the anchor agitator 22 drives the rotation of the pushing plate 221, it prompts the cleaning liquid to flow vertically upward through the notch 132, scouring the accumulations of fluid substances on both sides of the baffle 3 while cleaning the adhesion situation on the inner wall of the notch 132.

[0029] Embodiment Four:

[0030] On the basis of Embodiment Three, the protective layer 31 on the outer surface of the baffle 3 is set as a rubber layer. The rubber layer is evenly adhered to the outer surface of the baffle 3 through an adhesive to form a tightly adhered rubber surface layer. Different materials of rubber can be selected according to the type of the corresponding fluid substance. For example, for acidic fluid substances, butyl rubber or natural rubber can be selected, etc., to improve the corrosion resistance and service life of the baffle 3; Specific working process: On the basis of the specific working process in Embodiment Three, by adhering a rubber layer to the outer surface of the baffle 3, the outer surface of the baffle 3 is protected. In this way, when the fluid substance rotates and impacts the surface of the baffle 3 under the action of the agitator 2, the elastic protective layer 31 can shield the frictional impact on the main body of the baffle 3, thereby reducing the wear on the surface of the baffle 3; And the rubber surface protective layer 31 formed on the outside of the baffle 3 is relatively smooth and has a certain hydrophobicity, which reduces the adhesion force between the fluid substance and the surface of the baffle 3. Compared with the metal surface, viscous materials are less likely to adhere to the rubber surface, which is beneficial to reducing the adhesion situation on the baffle 3, keeping the inner wall of the tank body 1 clean, reducing material residue, and facilitating cleaning.

[0031] Embodiment Five:

[0032] On the basis of Embodiment 3, when it is different from Embodiment 4, in this embodiment, a new technical solution is provided for the setting of the protective layer 31. Specifically, the protective layer 31 on the outer surface of the baffle 3 is set as a rubber film 311, and the rubber film 311 is not directly adhered to the inclined surface of the baffle 3 near the inner wall of the tank body 1 on both sides, maintaining a deformation gap 312; An installation groove 14 is provided at the position of the inner wall of the tank body 1 corresponding to the baffle 3. The baffle 3 is slidably inserted into the installation groove 14, and then fixing parts such as bolts are used to realize the fixed connection between the baffle 3 and the installation groove 14, which is convenient for regular disassembly and maintenance of the baffle 3; And shielding plates 34 are provided at both ends of the baffle 3. The cross section of the shielding plate 34 is arc-shaped, and the end of the shielding plate 34 extends along the surface of the inner wall of the tank body 1 to both sides to realize the shielding protection of the gap between the baffle 3 and the installation groove 14. The rubber film 311 covers the edge end of the shielding plate 34; cleaning holes 313 are provided on the rubber film 311, and the positions of the flushing holes 32 and the cleaning holes 313 are staggered. Sealing blocks 35 are provided at the positions of the inclined surfaces on both sides of the baffle 3 corresponding to the cleaning holes 313. The end of the sealing block 35 is slidably inserted into the cleaning holes 313 to realize the sealing of the cleaning holes 313; Specific working process: On the basis of the specific working process in Embodiment 3, in the deformation gap 312 between the rubber film 311 and the outer surface of the baffle 3, in addition to the adhesion between the edge part of the rubber film 311 and the surfaces of the baffle 3 and the shielding plate 34, there is also at the tapered end position of the baffle 3, and the bonding area is established by filling glue in the combined part of the surface of the baffle 3 and the shielding plate 34. The bonding area extends vertically from one end of the baffle 3 to the other end, so that the rubber film 311 is closely attached to the inclined surfaces on both sides of the baffle 3 and the surface of the shielding plate 34 and remains in a taut state; When the normal fluid substance is stirred inside the tank body 1, because the rubber film 311 is in a tight state and closely adheres to the surface of the baffle 3, at this time the deformation gap 312 is small, and with the blocking effect of the sealing block 35 on the cleaning holes 313, it prevents the external fluid substance from penetrating into the deformation gap 312; when the fluid substance is discharged and the inner wall of the tank body 1 needs to be cleaned, the cleaning liquid is filled into the flushing cavity 33, so that the water pressure inside the flushing cavity 33 increases and accelerates through the flushing holes 32 and flows into the deformation gap 312, making the water pressure in the deformation gap 312 area increase, and the rubber film 311 deforms and bulges outwards, prompting the end of the sealing block 35 to separate from the cleaning holes 313, and the cleaning liquid can flow out from the cleaning holes 313 to wash and clean the fluid substance that may adhere to the outer surface of the baffle 3; and the deformation of the rubber film 311 prompts the adhesion gap between the fluid substance adhering to the outside of the baffle 3 and the surface of the rubber film 311 to be impacted by the deformation, prompting the fluid substance adhering to the outer surface of the rubber film 311 to be peeled off, thereby improving the cleaning efficiency of the complex surface of the inner wall of the tank body 1.

[0033] Furthermore, it is possible to choose to fill in a heated cleaning liquid, so that the area of the baffle 3 is heated, while the other areas of the inner wall of the tank body 1 are heated more slowly. The temperature difference causes differences in the deformation of different parts of the large-area layered adhesion substances adhered to the inner wall of the tank body 1, thereby accelerating their decomposition under the action of internal stress and detaching from the inner wall of the tank body 1; According to requirements, the flushing chamber 33 can extend into the shielding plate 34, and flushing holes 32 are provided on the surface of the shielding plate 34. Cleaning holes 313 are also provided in the corresponding rubber film 311 on the surface of the shielding plate 34. In this way, part of the cleaning liquid is filled into the deformation gap 312 on the surface of the shielding plate 34 through the flushing holes 32 on the surface of the shielding plate 34 and flows out from the cleaning holes 313. While the corresponding rubber film 311 on the surface of the shielding plate 34 is deformed, the bonding gap between the impact fluid substance and the shielding plate 34 is impacted, accelerating the peeling of the adhered impurities in the gap area between the shielding plate 34 and the baffle 3; and with the action of the stirrer 2, the rotational centrifugal force causes the cleaning liquid flowing out from the cleaning holes 313 to flow along the inner wall of the tank body 1, accelerating the shedding of the adhered fluid substances on the inner wall of the tank body 1 in the area between adjacent baffles 3, and improving the cleaning efficiency of the inner wall of the tank body 1.
