DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings shown in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0036] Embodiment one:

[0037] As shown in the drawings of the specification Figures 1-8 The application provides a fluid substance anti-adhesion stirring tank. The stirring tank comprises a tank body 1, a top cover 11 is mounted on the top of the tank body 1, a mounting frame is arranged at the bottom of the tank body 1, an agitator shaft 12 is rotatably arranged at the middle part of the top cover 11, the bottom of the agitator shaft 12 extends to a support seat on the inner wall of the tank body 1, an agitator 2 is arranged on the outer surface of the agitator shaft 12, the top of the agitator shaft 12 is connected with the output end of a power device on the upper side of the top cover 11, the power device can be selected from a motor device, and a baffle 3 is uniformly arranged around the agitator shaft 12 in the middle region of the inner wall of the tank body 1.

[0038] The cross section of the baffle 3 is triangular, the baffle 3 is hollow inside to form a flushing cavity 33, and a protective layer 31 is arranged on the outer surface of the baffle 3, which can be a rubber surface layer or a metal coating layer in the prior art to avoid wear of the baffle 3 due to stirring; flushing holes 32 are arranged on 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, and a water filling port 331 on the top of the baffle 3 extends to the upper surface of the top cover 11.

[0039] The flushing hole 32 in the application is conical, and the outer side opening is small, so that the fluid substance on the outside is difficult to penetrate inward, and the existing self-cleaning nozzle can be arranged inside the flushing hole 32 as needed, the spring-driven piston structure is built-in, the nozzle is automatically closed when the machine stops, and the flushing cavity 33 inside is washed out after starting, the flushing hole 32 opening is dredged, and the fluid substance inside the tank body 1 is prevented from causing blockage at the flushing hole 32 opening.

[0040] Specific working process: In industrial production, different types of fluid substances need to be fully mixed, and the possible existence of particle agglomerates and other substances is dispersed and dissolved to improve the characteristics of the fluid substance. The stirring tank equipment is used to fully stir the fluid substance.

[0041] Specifically, different types of fluid substances to be treated are filled into the tank body 1 from the liquid inlet on the top cover 11, and then 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 stir the fluid substance flowing into the tank body 1, and the fluid substance rotates around the stirring shaft 12 and is fully mixed in the rotating process. In order to improve the stirring effect of the fluid substance, the vertical baffle 3 is arranged on the inner wall of the tank body 1, and the baffle 3 is annularly distributed around the middle stirring shaft 12 to adjust the stirring condition of the fluid substance.

[0042] Specifically, the conical end of the baffle 3 points to the stirring shaft 12, and the part close to the inner wall of the tank body 1 on both sides is a bevel. In this way, as the stirrer 2 drives the fluid substance in the tank body 1 to rotate and flow, the part with higher density in the fluid substance, including possible particles, agglomerates and other parts, will gradually deviate to the area close to the inner wall of the tank body 1 due to centrifugal effect. This part of the fluid substance continues to rotate in the area close to the inner wall of the tank body 1 and may cause damage to the inner wall of the tank body 1 due to friction between the inner wall of the tank body 1 and the fluid substance. And this part of the fluid substance is far away from the stirring shaft 12, so the stirring effect is weakened, and because it contacts the inner wall of the tank body 1 and is subjected to friction resistance, the flow rate is easily slowed down and gathered in the area close to the inner wall of the tank body 1, and adhered to the surface of the inner wall of the tank body 1.

[0043] Therefore, by arranging the baffle 3, the part of the fluid substance rotating close to the inner wall of the tank body 1 is intercepted by the baffle 3, which destroys its state of gathering and continuously rotating in the outer ring area close to the inner wall of the tank body 1, and flows to the direction close to the stirring shaft 12 under the guidance of the bevel on both sides of the baffle 3, participates in the violent stirring under the action of the stirrer 2 in the middle area, and promotes the accelerated decomposition and dissolution of this part of the agglomerate into the whole fluid substance, which reduces the wear of the inner wall of the tank body 1.

[0044] And the guiding effect of the baffle 3 also promotes the fluid substance in the tank 1 to flow horizontally, and by adjusting the flow direction and path of the fluid substance in the tank 1, the fluid substance in the tank is caused to form a complex flow pattern, such as a combination of axial flow and radial flow, so that the fluid substance in the tank 1 is fully mixed;

[0045] And when the processed fluid substance is viscous, a dead zone that is prone to cause residual substances to adhere and accumulate and is difficult to clean is easily formed in the semi-enclosed area between the inclined surfaces on both sides of the baffle 3 and the inner wall of the tank 1 during subsequent cleaning, which causes inconvenience to the cleaning process; therefore, the baffle 3 is provided with a flushing cavity 33 inside, a control valve arranged at the water inlet 331 of the tubular structure at the top can be opened to connect the external cleaning liquid supply device, and the flushing cavity 33 is filled with cleaning liquid, which is combined with the cleaning liquid directly sent in through the liquid inlet, and the residual substances adhered to the inside of the tank 1 are cleaned by the rotation of the agitator 2;

[0046] The specific selection of the cleaning liquid can be selected according to the material of the tank 1 and the type of the processed fluid substance, for example, when the processed fluid substance is a water-soluble material such as sugar, inorganic salt, water-based paint, 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 an organic solvent, an emulsifier, etc., or an alkaline solution for cleaning by saponification reaction can be selected;

[0047] The cleaning liquid sprayed out of the flushing holes 32 on both sides of the baffle 3 directly acts on the dead zone position that may exist in the gap between the baffle 3 and the inner wall of the tank 1, so that the area is subjected to targeted impact cleaning, and the fluid substance adhered to the area is accelerated to fall off; the existence of the baffle 3 divides the middle area of the inner wall of the tank 1 into multiple smaller smooth areas, avoiding the occurrence of large-area sheet-shaped adhesion; the adhesion on the inner wall of the tank 1 is mainly small-area sheet-shaped adhesion, the contact area between the small-area sheet-shaped adhesion and the inner wall of the tank 1 is small, the adhesion effect is small, and the gap between the edge of the sheet-shaped adhesion and the inner wall of the tank 1 is larger, so that the agitated cleaning liquid can impact the gap to strip the small-area sheet-shaped adhesion from the inner wall of the tank 1, thereby improving the cleaning efficiency of the adhesion on the inner wall of the tank 1;

[0048] The cleaning liquid sprayed from the flushing hole 32 pointing to the inner wall of the tank 1 acts on the area of the inner wall of the tank 1 located between the gaps of the baffles, and for the sheet-shaped adhering material extending to the surface of the baffle 3, the flushing hole 32 is located between the sheet-shaped adhering material and the inner wall of the tank 1, and the sprayed cleaning liquid makes the sheet-shaped adhering material be impacted from the inside to the outside to accelerate the peeling off; cooperating with the action of the agitator 2, the cleaning liquid can more fully act on each area of the inner wall of the tank 1, realizing sufficient cleaning of the adhering viscous material on the inner wall of the tank 1, and ensuring the normal use of the mixing tank.

[0049] Embodiment two:

[0050] On the basis of embodiment one, the agitator 2 includes a paddle agitator 21 and an anchor agitator 22, the paddle agitator 21 is arranged at the middle part of the stirring shaft 12, and the anchor agitator 22 is arranged at the area close to the bottom of the stirring shaft 12.

[0051] The stirring shaft 12 is arranged in two sections, the paddle agitator 21 and the anchor agitator 22 correspond to different sections of the stirring shaft 12 respectively, and a shaft coupling 23 is arranged between the parts of the stirring shaft 12 corresponding to the paddle agitator 21 and the anchor agitator 22.

[0052] Specific working process: on the basis of the specific working process in embodiment one, for the fluid material with strong viscosity, in order to improve the stirring effect of the fluid material while reducing the adhesion of the fluid material on the inner wall of the tank 1, two kinds of agitators 2 are adopted in the present application, the agitator 2 located at the center of the tank 1 is a paddle agitator 21, which can be applied to a higher rotating speed and adopts a blade structure in the shape of an inclined blade, which promotes the downward flow of the fluid material close to the stirring shaft 12 while rotating, and after being blocked at the bottom, the fluid material flows upward along the area close to the inner wall of the tank 1 to supplement the upper area, realizing the circulation of the fluid material in the tank 1, and promoting the exchange of the fluid material in the vertical and horizontal directions.

[0053] The anchor agitator 22 is arranged at the position close to the bottom of the stirring shaft 12, the blade shape of the anchor agitator 22 is adapted to the arc-shaped curved part of the bottom of the tank 1, and the blade is close to the inner wall area of the bottom of the tank 1, so that when the anchor agitator 22 rotates, it can stir the fluid material while scraping and cleaning the fluid material adhering to the inner wall of the bottom of the tank 1, preventing its aggregation and deposition, so that the circulation of the fluid material in the tank 1 can be normally carried out.

[0054] Because the anchor stirrer 22 and the paddle stirrer 21 are suitable for different rotating speeds, the stirring shaft 12 can be provided in two sections, and the anchor stirrer 22 and the paddle stirrer 21 correspond to different sections of the stirring shaft 12, and a shaft coupling 23 is arranged between the two ends of the stirring shaft 12; as required, a driving motor can be arranged at the top and bottom of the stirring tank respectively to drive the corresponding stirring shaft 12 to work at a suitable rotating speed; the shaft coupling 23 can also be an electromagnetic shaft coupling controlled by an external controller, which is normally kept disconnected, and the power equipment controls the paddle stirrer 21 to work at a high rotating speed to stir the fluid material in the tank body 1; after stirring for a period of time, the power equipment is controlled to reduce the rotating speed, and the electromagnetic shaft coupling 23 is controlled to keep the upper and lower stirring shafts 12 rotating synchronously to clean the fluid material that may be deposited in the bottom area of the stirring tank, so as to avoid the situation that the fluid material is not mixed sufficiently due to the accumulation of the fluid material with a large density and the possible agglomerated particles in the bottom of the stirring tank.

[0055] Embodiment three:

[0056] On the basis of embodiment two, the inner wall of the tank body 1 is provided with an annular limiting block 13. There are many possible implementation schemes for the selection of the limiting block 13. The cross section of the limiting block 13 can be approximately trapezoidal, as shown in the accompanying drawings, the top surface is a horizontal plane supporting the upper side baffle 3, and the bottom surface is an inclined plane guiding the upward flow of the fluid material on the lower side; Figure 2

[0057] The cross section of the limiting block 13 can also be an isosceles triangle, and the upper and lower side surfaces are both inclined planes, which facilitates the downward flow of the fluid material during the discharging process, smoothly flows downward along the upper side inclined plane of the limiting block 13 and passes through the limiting block 13, reduces the obstruction of the limiting block 13 to the downward flow of the fluid material, and makes the discharging process more smooth; the user can select the type of the limiting block 13 according to the need;

[0058] The limiting block 13 is located in the gap region between the paddle stirrer 21 and the anchor stirrer 22 in the vertical direction; the horizontal bottom surface of the limiting block 13 is uniformly provided with stirring blocks 131, the cross section of the stirring block 131 is triangular, and the stirring blocks 131 are annularly distributed around the stirring shaft 12; the paddle of the anchor stirrer 22 is provided with a push plate 221, the push plate 221 is inclined, and the limiting block 13 is provided with a notch 132 at the positions corresponding to the two sides of the baffle 3, the notch 132 corresponds to the region where the dead zone is prone to occur between the two side surfaces of the baffle 3 and the inner wall of the tank body 1 in the vertical direction.

[0059] ​Specific working process: on the basis of the specific working process in embodiment two, because of gravity and centrifugal effect, the part with larger density in the fluid material and the possible agglomerate, particle part are gathered in the part close to the inner wall of the tank body 1 during the stirring process, especially the part close to the inner wall of the bottom of the tank body 1, these parts are less affected by the stirrer 2, and because of the friction of the inner wall of the tank body 1, the fluid material in these parts has poor flowability, and is prone to insufficient stirring, excessive aggregation and accumulation adhesion;

[0060] When the anchor stirrer 22 rotates, the fluid material in the part close to the inner wall of the bottom of the tank body 1 is separated and flows upward under the action of the circulation of the fluid material in the tank body 1, by arranging the annular limiting block 13, the part close to the inner wall of the tank body 1 in the fluid material flowing upward from the bottom of the tank body 1 is intercepted, so that the part close to the middle of the fluid material in the bottom of the tank body 1 which is fully stirred and mixed can flow upward smoothly, and the part flowing along the inner wall which is not fully stirred and mixed is intercepted and left in the bottom of the tank body 1, because the anchor stirrer 22 acts on the position close to the inner wall of the tank body 1, therefore the part of the fluid material left after being intercepted will be continuously stirred by the anchor stirrer 22, and be fully mixed and uniform;

[0061] For the part of the fluid material which is blocked, it will be gathered in the gap area between the blade end of the anchor stirrer 22 and the limiting block 13, with the rotation of the blade, this part of the flowing material 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 agglomerate, particles and the like in the fluid material flowing close to the inner wall are dispersed into the fluid material under the continuous impact, so that the fluid material is mixed more uniformly;

[0062] And because the limiting block 13 is provided with the notch 132, with the pushing plate 221 on the blade of the anchor stirrer 22 coinciding with the notch 132, part of the fluid material is pushed by the pushing plate 221 and forms an impact flow which impacts the area between the inner wall of the tank body 1 and the two sides of the baffle 3 through the notch 132, these areas may form dead zones where the fluid material is aggregated and are vertically impacted by the upward flowing impact flow of the notch 132, which promotes the diffusion of the fluid material which may be aggregated in these areas under the vertical impact, thereby reducing the situation that the fluid material is aggregated and adhered to the surface of the two sides of the baffle 3, and further reducing the adhesion on the inner wall of the tank body 1 after the fluid material is discharged;

[0063] Because the part of the fluid substance flowing inside the tank body 1 close to the inner wall of the bottom has a tendency to flow upward, especially for the part close to the lower side of the limiting block 13, because of the pushing effect of the pushing plate 221 on the paddle of the anchor type stirrer 22, the main movement state of the fluid substance passing through the position of the gap 132 is vertical flow, thereby reducing the adhesion of the fluid substance to the inner wall of the gap 132; and during the cleaning process, the cleaning liquid fills the bottom area inside the tank body 1, and as the anchor type stirrer 22 rotates with the pushing plate 221, the cleaning liquid is forced to flow vertically upward along the gap 132, thereby flushing the fluid substance accumulation on both sides of the baffle 3 and cleaning the adhesion to the inner wall of the gap 132.

[0064] Embodiment four:

[0065] On the basis of embodiment three, the protective layer 31 on the outer surface of the baffle 3 is provided as a rubber layer, which is uniformly adhered to the outer surface of the baffle 3 by an adhesive to form a tightly adhered rubber surface layer. Different materials of rubber can be selected according to the type of the fluid substance, for example, for acidic fluid substances, butyl rubber or natural rubber can be selected to improve the corrosion resistance and service life of the baffle 3.

[0066] Specific working process: on the basis of the specific working process in embodiment three, the outer surface of the baffle 3 is protected by adhering a rubber layer to the outer surface of the baffle 3, so that when the fluid substance rotates and impacts the surface of the baffle 3 under the action of the stirrer 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.

[0067] Moreover, the rubber surface protective layer 31 formed on the outer side of the baffle 3 is relatively smooth and has a certain hydrophobicity, which reduces the adhesion between the fluid substance and the surface of the baffle 3. Compared with a metal surface, viscous materials are less likely to adhere to the rubber surface, which is conducive to reducing the adhesion on the baffle 3, keeping the inner wall of the tank body 1 clean, reducing material residues, and facilitating cleaning.

[0068] Embodiment five:

[0069] On the basis of embodiment three, a new technical solution is provided for the protective layer 31 in this embodiment, specifically, the protective layer 31 on the outer surface of the baffle 3 is provided as a rubber film 311, which is not directly bonded between the inclined surface close to the inner wall of the tank body 1 on both sides of the baffle 3, and a deformation gap 312 is maintained.

[0070] A mounting groove 14 is provided at the position corresponding to the baffle 3 on the inner wall of the tank body 1, the baffle 3 is slidably embedded into the mounting groove 14, and then a fixing member such as a bolt is used to realize the fixed connection between the baffle 3 and the mounting groove 14, so that the baffle 3 can be conveniently disassembled and maintained regularly.

[0071] And the baffle 3 both sides end set shielding plate 34, shielding plate 34 cross section is arc-shaped, and shielding plate 34 end along the inner wall surface of the tank 1 extends to both sides, realize the shielding protection to the gap between baffle 3 and installation groove 14, rubber film 311 covers to the edge end of shielding plate 34;Rubber film 311 is provided with washing hole 313, and the position of flushing hole 32 and washing hole 313 is staggered, the baffle 3 both sides inclined surface and the part corresponding to washing hole 313 is provided with closure block 35, the end of closure block 35 is embedded in the washing hole 313, realize the closure of washing hole 313;

[0072] Specific working process: on the basis of the specific working process in example three, 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 surface of the baffle 3 and the shielding plate 34, there is a glue liquid filled in the position of the tapered end of the baffle 3 and the joint part of the surface of the baffle 3 and the shielding plate 34 to establish an adhesion area, which extends vertically from one side end of the baffle 3 to the other end, so that the rubber film 311 is tightly attached to the surface of the baffle 3 and the surface of the shielding plate 34 on both sides of the inclined surface and maintains a tight state;

[0073] When the normal fluid substance is inside the tank 1 and is subjected to stirring action, because the rubber film 311 is in a tight state and is tightly attached to the surface of the baffle 3, the deformation gap 312 is small at this time, and the closure and blockage of the washing hole 313 by the closure block 35 prevent external fluid substances from penetrating into the deformation gap 312;When the fluid substance is discharged and the inner wall of the tank 1 needs to be cleaned, the cleaning liquid is filled into the flushing cavity 33, so that the water pressure in the flushing cavity 33 increases and flows into the deformation gap 312 through the flushing hole 32, so that the water pressure in the deformation gap 312 area increases, the rubber film 311 deforms and bulges outward, prompting the end of the closure block 35 to separate from the washing hole 313, and the cleaning liquid can flow out of the washing hole 313, flushing and cleaning the fluid substances that may be adhered to the outer surface of the baffle 3;And the deformation of the rubber film 311 causes the fluid substances adhered to the outer side of the baffle 3 to be impacted by the deformation gap between the surface of the rubber film 311, causing the fluid substances adhered to the outer surface of the rubber film 311 to be stripped off, thereby improving the cleaning efficiency of the complex surface of the inner wall of the tank 1.

[0074] Further, the heated cleaning liquid can be selected to be filled, so that the area of the baffle 3 is heated, while the other areas of the inner wall of the tank 1 are heated slowly, and the temperature difference causes the deformation difference of different parts of the large-area layered adhering substances adhered to the inner wall of the tank 1, thereby accelerating the decomposition of the substances under the action of internal stress and separating from the inner wall of the tank 1;

[0075] According to the need, the flushing cavity 33 can extend to the inside of the shielding plate 34, and the flushing hole 32 is arranged on the surface of the shielding plate 34, and the corresponding rubber film 311 on the surface of the shielding plate 34 is also provided with a cleaning hole 313, so that part of the cleaning liquid flows into the deformation gap 312 on the surface of the shielding plate 34 from the flushing hole 32 on the surface of the shielding plate 34, and flows out from the cleaning hole 313, so that the rubber film 311 corresponding to the surface of the shielding plate 34 is deformed, and the combined gap between the impact fluid material and the shielding plate 34 is accelerated, and the peeling of the adhered impurities in the gap area between the shielding plate 34 and the baffle 3 is accelerated; and with the action of the stirrer 2, the rotation centrifugal effect promotes the cleaning liquid flowing out of the cleaning hole 313 to flow along the inner wall of the tank 1, accelerates the peeling of the adhered fluid material on the inner wall of the tank 1 in the area between the adjacent baffles 3, and improves the cleaning efficiency of the inner wall of the tank 1.
