[0041] The inventor has found that for large-sized tanks, the stirring baffle is usually directly welded with the tank body, and for small-sized sanitary-grade containers, workers cannot enter the tank cylinder section, so the traditional fixed-welded stirring baffle has the problems of welding difficulty and inability to polish. In addition, due to the shielding of the stirring baffle, the radiographic testing of the cylinder and head butt joint is affected. Meanwhile, in some laboratory devices, in order to test the influence of the stirring baffle on the mixing effect of the material, the stirring baffle needs to be installed and removed.

[0042] Based on this, the present application provides a stirring baffle assembly to solve the above technical problems, with reference to the following embodiments.

[0043] Referring to Figure 1 , Figure 2 An embodiment of the present application discloses a stirring baffle assembly, which is suitable to be arranged in a tank body 20. The stirring baffle assembly comprises a stirring baffle 1, a first support 21, and a second support 22. The stirring baffle 1 comprises a plate body 10, a positioning part 11, and a fixing part 12. The positioning part 11 and the fixing part 12 are arranged at intervals along the length direction of the plate body 10 on the plate body 10. The first support 21 is used to be connected with the inner wall of the tank body 20, and the positioning part 11 is inserted and matched with the first support 21. The second support 22 is used to be connected with the inner wall of the tank body 20, and the fixing part 12 is detachably connected with the second support 22.

[0044] The stirring baffle assembly provided by the application is detachably connected between the stirring baffle 1 and the tank body 20 by arranging the positioning part 11 and the fixing part 12 on the plate body 10 of the stirring baffle 1, the positioning part 11 is insertedly matched with the first support 21 connected to the tank body 20, and the fixing part 12 is detachably connected with the second support 22 on the tank body 20. When the stirring baffle 1 is installed, one end of the stirring baffle 1 is first positioned by the positioning part 11, and then the other end of the stirring baffle 1 is fixed to the second support 22 by the fixing part 12, in other words, only one end of the stirring baffle 1 needs to be fastened, which can simplify the installation and removal operation of the stirring baffle compared with the fastening of both ends.

[0045] Meanwhile, since the stirring baffle 1 of the application is detachable, the stirring baffle 1 can be taken out of the tank body 20 when performing a radiographic inspection, so that the shielding can be avoided. The stirring baffle can also be disassembled and replaced according to the experimental needs.

[0046] Specifically, the positioning part 11 and the first support 21 are insertedly matched, which at least limits the freedom of movement of the stirring baffle 1 in the direction perpendicular to the length direction of the stirring baffle 1. For example, the positioning part 11 and the first support 21 can adopt a bolt structure to realize shaft hole matching; the positioning part 11 and the first support 21 can also adopt a recess structure and a protruding structure matched with each other.

[0047] For example, the Z direction in the figure can correspond to the length direction of the plate body 10, the X direction in the figure can correspond to the width direction of the plate body 10, and the Y direction in the figure can correspond to the thickness direction of the plate body 10.

[0048] Referring to Figures 2 to 4 In one embodiment, the positioning part 11 includes an inserted rod 110, the first support 21 is provided with a positioning hole 210, one end of the inserted rod 110 is connected to the plate body 10, and the other end of the inserted rod 110 is insertedly matched with the positioning hole 210.

[0049] Specifically, the inserted rod 110 can be inserted into the positioning hole 210 to form a bolt structure. The inserted rod 110 is preferably fixed to the lower half area of the side surface of the plate body. When the stirring baffle 1 is installed, the inserted rod 110 and the positioning hole 210 can be insertedly matched to facilitate the positioning of one end of the stirring baffle 1. For example, the inserted rod 110 can be welded and fixed to the side surface of the plate body. Of course, the inserted rod 110 and the plate body 10 can also be fixedly connected by other connection methods such as threaded connection or riveting.

[0050] In another embodiment, the positioning part 11 can be a positioning hole opened in the bottom of the plate body 10, and correspondingly, an inserted rod can be arranged on the first support 21 to achieve inserted matching.

[0051] Referring to Figure 3 As shown in one of the embodiments, the insertion rod 110 comprises a first main rod body 111 and a first connecting rod 112, the first connecting rod 112 is connected between the plate body 10 and the first main rod body 111, the first main rod body 111 and the first connecting rod 112 are connected at an angle, and the first main rod body 111 is parallel to the plate body 10.

[0052] Specifically, the insertion rod 110 is an L-shaped rod, and the included angle between the first main rod body 111 and the first connecting rod 112 is preferably 90 degrees. The length direction of the first main rod body 111 is parallel to the plane in which the plate body 10 lies, and the length direction of the first main rod body 111 is preferably parallel to the length direction of the plate body 10. In this way, when the stirring baffle 1 is installed, the first main rod body 111 of the insertion rod 110 can be inserted into the positioning hole 210 on the first support 21 along the extension direction of the plate body 10, thereby achieving positioning.

[0053] Exemplarily, a round steel can be bent into an L-shaped insertion rod 110, and the end of the insertion rod 110 used for insertion has a chamfer. The first support 21 is a rod, and the first support 21 is welded and fixed to the inner wall of the tank body 20. The first support 21 can be a round steel, and the first support 21 has a circular through hole, which is the positioning hole 210. The end of the first support 21 is processed into a spherical surface to avoid edges and corners.

[0054] Referring to Figure 5 As shown in one of the embodiments, the fixing portion 12 comprises a first fixing hole 120, and the first fixing hole 120 penetrates the plate body 10 along the thickness direction of the plate body 10. The second support 22 is provided with a second fixing hole 220 opposite to the first fixing hole 120. The stirring baffle assembly further comprises a fastener 23, and the fastener 23 is connected through the first fixing hole 120 and the second fixing hole 220 to fix the stirring baffle 1 to the second support 22. Through the cooperation of the fastener 23 passing through the first fixing hole 120 and the second fixing hole 220, the end of the stirring baffle 1 is detachably connected to the second support 22. After one end of the stirring baffle 1 is positioned, only the fastener 23 at the other end is fastened or loosened to realize convenient disassembly and assembly of the stirring baffle 1.

[0055] For example, fastener 23 is threadedly connected to second fixing hole 220. Second fixing hole 220 is a threaded blind hole. Fastener 23 includes a flat-end screw 231 and a cap nut 232. Flat-end screw 231 is passed through first fixing hole 120 in stirring baffle 1 and then screwed into second fixing hole 220. Finally, cap nut 232 covers the exposed end of flat-end screw 231, thereby securing the end of stirring baffle 1 to second support member 22. The cap nut 232 and flat-end screw 231 work together to protect the end of fastener 23 and facilitate cleaning and sterilization, thereby improving the hygienic performance of the product.

[0056] In other embodiments, the fastener 23 and the second fixing hole 220 may also be connected by snap-fit ​​connection or detachable riveting.

[0057] Reference Figure 1 、 Figure 5 As shown, in one embodiment, the second support member 22 includes a second main rod body 221 and a second connecting rod 222, the second main rod body 221 and the second connecting rod 222 are connected at an angle, the second main rod body 221 is perpendicular to the plate body 10, and the second fixing hole 220 is arranged at the end of the second main rod body 221 away from the second connecting rod 222.

[0058] Among them, the plate body 10 is fixed to the end of the second main rod body 221 away from the second connecting rod 222 by the fastener 23, so that the plate body 10 is perpendicular to the second main rod body 221, and the second support member 22 provides support force for the stirring baffle 1 in the direction perpendicular to the plate body, which can increase the structural strength and ensure the stability of the stirring baffle 1 during the stirring process.

[0059] Specifically, the second support member 22 is an L-shaped rod, and the angle formed between the second main rod body 221 and the second connecting rod 222 is preferably 90 degrees. The plate body 10 is attached to the end surface of the second main rod body 221.

[0060] For example, a round steel bar can be bent into an L-shaped rod to serve as the second support member 22 . The second support member 22 is welded and fixed to the inner wall of the tank body 20 , and a threaded hole is provided at the end of the second support member 22 .

[0061] Reference Figure 1 、 Figure 4 、 Figure 5 As shown, in one embodiment, the first support member 21 and the second support member 22 are disposed on the same side of the plate 10 .

[0062] Among them, the plug-in fitting position between the positioning portion 11 and the first support member 21 and the detachable fixed connection position between the fixing portion 12 and the second support member 22 are located on the same side of the plate body 10, which is convenient for installation and disassembly operations on this side. At the same time, the opposite side of the plate body 10 can block the flow of fluid and reduce the impact of fluid impact on the connection stability.

[0063] The installation process of the stirring baffle assembly is as follows: the second support 22 and the first support 21 are fixed to the tank body 20 in a top-down arrangement, the insertion rod 110 fixed to the lower part of the stirring baffle 1 is inserted into the positioning hole 210 of the first support 21 to position the stirring baffle 1, and then the upper part of the stirring baffle 1 is detachably fixed to the second support 22 by the fastener 23, so that the stirring baffle 1 is fixed to the tank body 20. When disassembly is needed, the upper part of the stirring baffle 1 is first detached from the second support 22, and then the stirring baffle 1 is moved to pull out the insertion rod 110 from the positioning hole 210.

[0064] Referring to Figure 6 Another embodiment of the present application discloses a stirring device, as shown in the figure, the stirring device 100 comprises a tank body 20 and a stirring mechanism 3, and the stirring mechanism 3 is arranged in the tank body 20.

When the stirring baffle 1 is installed, one end of the stirring baffle 1 is first positioned by the positioning part 11, and then the other end of the stirring baffle 1 is fixed to the second support 22 by the fixing part 12. In other words, only one end of the stirring baffle 1 needs to be fastened, which is more convenient than fastening both ends.

[0066] Meanwhile, when the stirring device 100 works, the material (such as liquid) in the tank body 20 will rotate together with the rotating direction of the paddle of the stirring mechanism 3, the liquid in the middle part of the tank body 20 will flow to the tank wall due to the centrifugal force, so that the liquid level at the tank wall rises and the liquid level in the middle region decreases, forming a vortex. The stirring baffle 1 can change the tangential flow into radial flow and axial flow, eliminate the vortex, improve the main circulation, increase the degree of turbulence, and improve the stirring effect.

[0067] Referring to Figure 6 In one embodiment, the stirring baffle 1 is arranged in a spaced manner with the inner wall of the tank body 20 to form a gap 24. The gap 24 between the stirring baffle 1 and the tank body 20 can be used for the material in the tank body 20 to pass through in the circumferential direction, so as to improve the flow effect.

[0068] Specifically, the first support 21 and the second support 22 protrude outwards from the plate body 10 towards the center of the tank body 20 to form a gap 24 after the stirring baffle 1 is installed.

[0069] Referring to Figure 6 As shown in the figure, in one embodiment, the axis direction of the tank body 20 is arranged in the vertical direction, and the positioning part 11 is located below the fixing part 12. In this embodiment, the positioning point of the lower end of the detachable stirring baffle 1 is an ear insertion type, and only the fixing point of the upper end needs to be fastened.
