Description

Technical Field

[0001] The invention relates to the technical field of stirring kettle baffle structures, in particular to a variable-angle tapered flange spiral baffle structure and a stirring kettle. Background Art

[0002] A stirred tank is an industrial product primarily used in chemical production processes such as mixing, reaction, and polymerization. Its structure typically consists of a tank body, agitator, and heating jacket. Materials include stainless steel, carbon steel, and polyethylene (PE). Temperature control can be achieved through various methods, including electric heating, steam heating, and water bath heating.

[0003] Adding baffles to a stirred tank can break up stirring vortices, creating turbulence and improving stirring efficiency and mixing quality. However, existing baffles are fixed and cannot be adjusted to accommodate materials of varying viscosities, resulting in reduced efficiency. Furthermore, straight baffles offer limited improvement in axial mixing and require high-power, high-speed stirring to achieve rapid mixing. To address this issue, we propose a variable-angle, tapered-flange spiral ribbon baffle structure and a stirred tank. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a variable-angle tapered flange spiral baffle structure and a stirring kettle, which solve the problems that the existing stirring kettle baffles cannot adapt to the viscosity of different materials and have poor axial mixing effect.

[0005] To achieve the above object, the present invention provides the following technical solutions: A variable-angle tapered flange spiral baffle structure and a stirring kettle, comprising a plate body; The screw belt body is fixedly mounted on the outer periphery of the plate body; A bracket, used to fix the plate in the stirring tank; The adjusting component is used to adjust the angle between the plate and the bracket.

[0006] As a preferred technical solution, a protrusion is formed on the outer peripheral side of the spiral ribbon body.

[0007] As a preferred technical solution, the diameter of the spiral ribbon body gradually decreases from top to bottom at 5% per turn, and the climbing angle of the spiral ribbon body is 15°-30°.

[0008] As a preferred technical solution, the adjusting component includes a rotating shaft, the rotating shaft is rotatably connected to the bracket, and the rotating shaft is fixedly connected to the plate body.

[0009] As a preferred technical solution, the adjusting component further includes a fixing plate, one end of which is fixedly connected to the bracket, a locking bolt is threadedly connected to the fixing plate, and one end of the locking bolt abuts against the rotating shaft.

[0010] As a preferred technical solution, the rotating shaft is provided with a plurality of insertion holes for inserting one end of a locking bolt to fix the plate body to an angle of 90°, 120°, 135°, 150° or 180° with the inner wall of the stirring tank.

[0011] As a preferred technical solution, the ratio of the protrusion height to the spiral ribbon width is 1:5.

[0012] As a preferred technical solution, the length of the plate body is 0.6 to 0.7 times the length of the stirring tank, and the width of the plate body is 0.05 to 0.1 times the diameter of the stirring tank.

[0013] As a preferred technical solution, a triangular plate is fixedly connected to the bracket.

[0014] A second aspect of an embodiment of the present invention provides a stirring kettle, comprising the variable-angle tapered flange spiral baffle structure, wherein the bracket is fixedly connected to the inner peripheral wall of the stirring kettle.

[0015] By means of the above technical solution, the present invention provides a variable angle tapered flange spiral baffle structure and a stirring kettle. It has at least the following beneficial effects: (1) The variable angle tapered flange spiral baffle structure and the stirring kettle can adjust the angle of the baffle body according to the working conditions of materials with different viscosities to achieve the best balance between stirring power consumption and mixing effect. The tapered flange spiral ribbon on the outside of the baffle body can be used to lift the bottom material to the top through the spiral ribbon body. When the liquid reaches the top of the spiral ribbon, it flows back to the bottom by gravity, achieving axial mixing and lifting, which can promote the upward and downward flow of materials and solve the problem of difficult axial mixing.

[0016] (2) The variable angle tapered flange spiral baffle structure and the stirring kettle can further change the direction of movement of the material hitting the spiral body by providing a protrusion on the spiral body, thereby improving the multi-angle mixing effect of the material and further improving the lifting effect of the material on the spiral belt.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1 See also Figures 1-4 This embodiment provides a variable-angle tapered flange spiral baffle structure, which is used to be set on the inner wall of the stirring tank to break the stirring vortex, form turbulence and thus improve the stirring efficiency and mixing effect.

[0021] The variable angle tapered flange spiral baffle structure comprises: Plate 1; The spiral ribbon body 2 is fixedly mounted on the outside of the plate body 1; Bracket 3, used to fix the plate 1 in the stirring tank; The adjusting component 4 is used to adjust the angle between the plate body 1 and the bracket 3.

[0022] See also Figure 2 The plate body 1 is a cubic structure, and the length of the plate body 1 is 0.6 times to 0.7 times the length of the stirring tank, and the width of the plate body 1 is 0.05 times to 0.1 times the diameter of the stirring tank. Preferably, the length of the plate body 1 is 2 / 3 of the length of the stirring tank, and the width of the plate body 1 is 1 / 10 of the diameter of the stirring tank.

[0023] See also Figure 2 The spiral ribbon body 2 is a continuous spiral ribbon structure. The top of the spiral ribbon body 2 is fixedly connected to the top edge of the plate body 1, and the bottom end of the spiral ribbon body 2 is fixedly connected to the bottom edge of the plate body 1, further destroying the vortex and improving the local mixing ability.

[0024] The spiral ribbon body 2 is gradually tapered from top to bottom at a tapering ratio of 5%. The climbing angle of the spiral ribbon body 2 is 15°-30°. The specific implementation angle can be confirmed according to the applicable working conditions of the stirring tank. As the viscosity increases, the climbing angle gradually increases, generally 20°.

[0025] See also Figure 4 The outer peripheral side of the spiral ribbon body 2 protrudes outward to form a protrusion 201, and the ratio of the height of the protrusion 201 to the width of the spiral ribbon is 1:5. By setting the protrusion 201, the movement direction of the material hitting the spiral ribbon body 2 can be further changed, thereby improving the multi-angle mixing effect of the material.

[0026] See also Figure 2 A triangular plate 301 is fixedly connected to the bracket 3 to enhance the strength and supporting capacity of the bracket 3 .

[0027] Furthermore, the number of the brackets 3 is at least two, and the two brackets 3 are respectively arranged at the upper and lower ends of the baffle 1 to improve the stability of the baffle 1.

[0028] See also Figure 3 The adjusting component 4 includes a rotating shaft 401 . The rotating shaft 401 can be a whole shaft that passes through the baffle 1 , or can be two shafts installed at both ends of the baffle 1 .

[0029] Furthermore, there are two rotating shafts 401, and the opposite ends of the two rotating shafts 401 are rotatably connected to the two brackets 3 respectively, and the opposite ends of the two rotating shafts 401 are fixedly connected to the two ends of the plate body 1 respectively. By setting the rotating shafts 401, the baffle 1 can rotate relative to the bracket 3.

[0030] Furthermore, the adjustment component 4 also includes a fixing plate 402, the bottom end of which is fixedly connected to the upper surface of the bracket 3. A locking bolt 403 is threadedly connected to the inner wall of the fixing plate 402, and a knob is provided at one end of the locking bolt 403. The rotating shaft 401 is provided with a plurality of insertion holes 404 for inserting one end of the locking bolt 403. The other end of the locking bolt 403 can pass through the fixing plate 402 and insert into the insertion holes 404, thereby limiting the position of the rotating shaft 401 and preventing the baffle 1 and the rotating shaft 401 from rotating and changing angle due to the impact of material.

[0031] Specifically, by engaging the locking bolt 403 with the insertion hole 404 , the plate 1 can be fixed at an angle of 90°, 120°, 135°, 150°, or 180° to the inner wall of the stirring tank.

[0032] Therefore, the angle of the baffle 1 can be adjusted according to the viscosity parameters of the stirring material working condition. When the material is in a low viscosity (0cp-5000cp) state, the angle between the baffle 1 and the inner wall of the stirring tank is adjusted to 90°. When the material is in a medium viscosity (5000cp-50000cp) state, the angle between the baffle 1 and the inner wall of the stirring tank is adjusted to 120°. When the material is in a high viscosity (50000cp-500000cp) state, the angle between the baffle 1 and the inner wall of the stirring tank is adjusted to 135°. When the material is in an ultra-high viscosity (>500000cp) state, the angle between the baffle 1 and the inner wall of the stirring tank is adjusted to 150°-180°. By changing the angle between the baffle 1 and the inner wall of the stirring tank, the waste of stirring power caused by the baffle 1 can be reduced, and the effect of the baffle 1 can be avoided to gradually decrease with the increase of viscosity under the condition of consistent stirring speed.

[0033] Example 2 See also Figure 1 This embodiment provides a stirring kettle, including the variable-angle tapered flange spiral baffle structure in the first embodiment, and the bracket 3 is fixed to the inner peripheral wall of the stirring kettle by welding.

[0034] When the variable-angle tapered flange spiral baffle structure and the stirring kettle of the present invention are in use, before adding materials to the stirring kettle, the baffle angle is confirmed according to the viscosity of the material. The specific method is: first loosen the locking bolt 403 so that the rotating shaft 401 is released and can rotate freely, and then adjust the angle of the baffle 1. After the angle is adjusted to the right position, rotate the locking bolt 403 in the opposite direction so that one end of the locking bolt 403 enters the corresponding socket 404 to lock the rotating shaft 401, and the angle adjustment of the baffle 1 is completed.

[0035] Then, the material is added into the stirring kettle. After the material is added into the stirring kettle, the stirring kettle is turned on to stir. The material in the kettle obtains horizontal movement power. When the material hits the spiral ribbon body 2, the material climbs along the spiral ribbon body 2. The material on the top of the spiral ribbon body 2 continuously flows back to the bottom of the stirring kettle by gravity, and the axial mixing is completed over and over again.

[0036] When the material hits the baffle 1, the baffle 1 forces the material to change its direction of movement, wherein the material moving toward the center of the mixing tank is fully mixed with the material that has not passed through the baffle, that is, radial mixing.

[0037] Through the above steps, by changing the angle of the baffle 1, the stirring power is reduced, the axial mixing and promotion of the material is achieved by the spiral ribbon body 2, and the radial mixing of the material is achieved by the variable angle baffle 1.
