Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment, specifically relating to a paddle used for chemical stirring and defoaming. Background Technology

[0002] Chemical mixing is an important process in chemical engineering, mainly used to mix different substances (such as liquids, solids, and gases) uniformly to achieve specific reaction, dispersion, or dissolution effects. Chemical mixing is a complex but crucial process, involving the comprehensive consideration of multiple factors. Through proper mixing design and operation, the efficiency of chemical reactions and the quality of products can be significantly improved.

[0003] In actual production, traditional chemical agitators mostly use fan-shaped blades to agitate chemical raw materials. However, the strong shear force generated by the fan-shaped blades during agitation can easily draw in gas from the liquid, forming bubbles. Furthermore, the high-speed flow of fluid around the blades can cause gas to be entrained, especially at high speeds. The presence of bubbles may interfere with the contact between reactants and reduce the efficiency of the chemical reaction. At the same time, existing chemical agitators also have the disadvantage of difficulty in quickly adjusting the agitation height. Therefore, in order to improve the uniformity of agitation of chemical raw materials and ease of use, a blade for defoaming in chemical agitation is proposed to solve this problem. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a paddle for chemical stirring and defoaming, which has the advantages of rapid and precise adjustment of stirring height and defoaming during stirring.

[0005] To achieve the above objectives, this utility model provides a paddle for chemical stirring and defoaming, comprising a mobile platform; two vertical frames are vertically arranged on the upper surface of the mobile platform; linear guide rails are vertically arranged on the sides of the two vertical frames, and guide rail sliders are fitted on the two linear guide rails.

[0006] A movable plate is installed between the two guide rail sliders. A support plate is installed on the side of the movable plate. A speed reducer is mounted on the side of the support plate. A motor is mounted on the speed reducer. The output end of the motor is connected to the input end of the speed reducer. A stirring transmission rod is connected to the output end of the speed reducer.

[0007] The stirring transmission rod is externally fitted with a clamp, and connecting rods are installed on both sides of the clamp. Transmission flat steel is horizontally installed inside each of the two connecting rods, and several stirring flat steels are vertically arranged on all four sides of the transmission flat steel.

[0008] Two crossbeams are also vertically installed between the two vertical frames, and a height adjustment assembly is installed between the two crossbeams.

[0009] As a further improvement of this utility model, the transmission flat steel is arranged in a rectangular strip shape, and several of the stirring flat steels are arranged in a cross shape along the outside of the transmission flat steel.

[0010] As a further improvement of this utility model, some of the stirring flat steel bars have a length of 200 mm, a width of 22 mm, and a thickness of 4 mm.

[0011] As a further improvement of this utility model, the height adjustment assembly includes a height adjustment seat disposed between two objects. The height adjustment seat is U-shaped and has bearing rings installed on both sides. A threaded screw is rotatably disposed between the two bearing rings. A screw nut is externally engaged with the threaded screw.

[0012] As a further improvement of this utility model, a slider seat is sleeved on the outside of the lead screw nut, and a connecting plate is installed on the side of the slider seat. The side of the connecting plate extends and connects to the moving plate. Two side rods are installed on the height adjustment seat. The two side rods are respectively set on one side of the threaded lead screw and both pass through the slider seat. A reciprocating motor is installed on one side of the height adjustment seat. The output end of the reciprocating motor passes through one side of the height adjustment seat and extends to connect to one end of the threaded lead screw.

[0013] As a further improvement of this utility model, a chemical mixing platform is installed on the upper surface of the mobile platform, and a chemical tank body is supported on the chemical mixing platform. A detachable tank cover is provided on the chemical tank body; the clamp is arranged vertically and several stirring flat steel bars are all arranged inside the chemical tank body.

[0014] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0015] This utility model discloses a paddle for defoaming in chemical mixing. In practical use, when the mixing drive rod rotates, several flat mixing steels installed on both sides of the mixing drive rod can rotate with the rotation of the mixing drive rod. Compared with the traditional fan-shaped circumferential mixing blades, the horizontally arranged and cross-shaped arrangement of the flat mixing steels in this application can increase the shear force during the mixing process, making it easier to break bubbles in the liquid. The generated shear force will break the bubbles on the liquid surface. As the paddle rotates, the bubbles break and the gas escapes into the air, thereby completing the defoaming mixing. At the same time, the flat array design of the flat mixing steels can effectively break bubbles and reduce foam generation, especially in liquids with high viscosity or high surface tension, thereby effectively improving the defoaming mixing in chemical mixing.

[0016] The impeller of this utility model for chemical mixing and defoaming utilizes the coordinated movement of multiple structures within a height adjustment assembly. This allows a sliding connecting plate to drive the motor and mixing transmission rod to adjust their overall height. Compared to traditional fixed mixing heights, the mixing transmission rod of this application can adapt to chemical tanks of various sizes and shapes, thereby increasing the flexibility and versatility of the chemical mixing equipment. Furthermore, by adjusting the length of the mixing flat steel, the adaptability to the chemical tank body can be further improved. By adjusting the mixing height of the mixing transmission rod, users can effectively reduce the mixing dead zone within the chemical tank body, ensuring thorough mixing of chemical raw materials.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Depend on Figure 1-4The present invention provides a paddle for chemical stirring and defoaming, comprising a mobile platform 1; two vertical frames 2 are vertically arranged on the upper surface of the mobile platform 1; linear guide rails 3 are vertically arranged on the sides of the two vertical frames 2, and guide rail sliders 4 are fitted on the two linear guide rails 3.

[0025] A movable plate 5 is installed between two guide rail sliders 4. A support plate 6 is installed on the side of the movable plate 5. A reducer is mounted on the side of the support plate 6. A motor 7 is mounted on the reducer. The output end of the motor 7 is connected to the input end of the reducer. The output end of the reducer is connected to a stirring transmission rod 8.

[0026] The stirring transmission rod 8 is externally fitted with a clamp 81. Connecting rods 82 are installed on both sides of the clamp 81. Transmission flat steel 83 is horizontally installed inside the two connecting rods 82. Several stirring flat steels 84 are vertically arranged on all four sides of the transmission flat steel 83.

[0027] Two horizontal beams 21 are also vertically installed between the two vertical frames 2, and a height adjustment component 9 is installed between the two horizontal beams 21.

[0028] In this embodiment, compared to the traditional fan-shaped circumferential stirring blades, the stirring flat steel 84 in this application, which is arranged laterally and in a cross-shaped pattern, can increase the shear force during the stirring process, making it easier to break bubbles in the liquid. The generated shear force will break the bubbles on the liquid surface. As the blades rotate, the bubbles break and the gas escapes into the air, thereby completing the defoaming stirring. At the same time, the flat array design of the stirring flat steel 84 can effectively break bubbles and reduce foam generation, especially in liquids with high viscosity or high surface tension, thereby effectively improving the defoaming stirring in chemical stirring.

[0029] Furthermore, through the mutual movement and coordination of multiple structures set within the height adjustment assembly 9, the sliding connecting plate 96 can drive the motor 7, reducer, and stirring transmission rod 8 to adjust their overall height. Compared to the traditional fixed stirring height, the stirring transmission rod 8 of this application can adapt to chemical tank bodies 11 of various sizes and shapes, thereby increasing the flexibility and versatility of the chemical stirring equipment. At the same time, by adjusting the length of the stirring flat steel 84, the adaptability to the chemical tank body 11 can be further improved. Users can effectively reduce the stirring dead zone within the chemical tank body 11 by adjusting the stirring height of the stirring transmission rod 8, ensuring thorough mixing of chemical raw materials.

[0030] Specifically, refer to Figure 3-4 The transmission flat steel 83 is arranged in a rectangular strip shape, and several stirring flat steels 84 are arranged in a cross shape along the outside of the transmission flat steel 83.

[0031] In this embodiment, during use, the horizontally arranged and cross-shaped stirring flat steel 84 can increase the shear force during the stirring process, making it easier to break the bubbles in the liquid. The generated shear force will break the bubbles on the liquid surface. As the blades rotate, the bubbles break and the gas escapes into the air, thereby completing the defoaming stirring.

[0032] Specifically, refer to Figure 3-4 Several 84-strength stirring flat steel bars, each 200mm long, 22mm wide, and 4mm thick.

[0033] In this embodiment, in actual design, as in the example... Figure 3-4 As shown, the stirring flat steel 84 is arranged in a cross-shaped array along the outside of the transmission flat steel 83. The user can further improve the adaptability to the chemical tank body 11 by adjusting the length of the stirring flat steel 84; at the same time, the transmission flat steel 83 is adjusted according to the diameter of the stirring flat steel 84.

[0034] Specifically, refer to Figure 1-2 The height adjustment assembly 9 includes a height adjustment seat 91 disposed between the two 21s. The height adjustment seat 91 is U-shaped and has bearing rings 92 installed on both sides. A threaded screw 93 is rotatably disposed between the two bearing rings 92. A screw nut 94 is externally engaged with the threaded screw 93.

[0035] In this embodiment, the height adjustment seat 91 has protrusions on both sides, which can be used to assemble the bearing rings 92. The two bearing rings 92 on the height adjustment seat 91 can ensure the rotational stability of the threaded screw 93 and reduce the rotational vibration of the threaded screw 93, thereby ensuring that the threaded screw 93 will rotate stably under load.

[0036] Specifically, refer to Figure 1-2 A slider seat 95 is sleeved on the outside of the lead screw nut 94. A connecting plate 96 is installed on the side of the slider seat 95, and the side of the connecting plate 96 extends to connect with the moving plate 5. Two side rods 97 are installed on the height adjustment seat 91. The two side rods 97 are respectively set on one side of the threaded lead screw 93 and both pass through the slider seat 95. A reciprocating motor 98 is installed on one side of the height adjustment seat 91. The output end of the reciprocating motor 98 passes through one side of the height adjustment seat 91 and extends to connect with one end of the threaded lead screw 93.

[0037] In this embodiment, when the threaded screw 93 rotates, it is laterally limited by the two side rods 97 on the slider seat 95. At this time, the screw nut 94 engaged outside the threaded screw 93 will drive the slider seat 95 and the connecting plate 96 to reciprocate linearly along the stroke range of the threaded screw 93.

[0038] Furthermore, the reciprocating motor 98 is a mature existing technology, its power connection method is existing technology, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0039] Specifically, refer to Figure 1 A chemical mixing table 10 is installed on the upper surface of the mobile platform 1. A chemical tank body 11 is mounted on the chemical mixing table 10. A detachable tank cover is installed on the chemical tank body 11. The clamping parts 81 are arranged vertically and several mixing flat steels 84 are all installed inside the chemical tank body 11.

[0040] In this embodiment, the chemical mixing platform 10 is used to install the chemical tank body 11. The chemical tank body 11, in use, functions as described in the embodiment. Figure 1 As shown, a through hole is provided at the top of the tank cover. The through hole can be used to allow the stirring transmission rod 8 to be inserted vertically, so that the stirring transmission rod 8 can extend into the interior of the chemical tank body 11 to stir the chemical raw materials.

[0041] The impeller of this utility model is used for chemical stirring and defoaming:

[0042] Step 1: When the user needs to stir chemical raw materials, they pour them into the chemical tank body 11, and then connect the motor 7 to an external power source. When the motor 7 is running, through the transmission connection between the motor 7 and the reducer, and the transmission connection between the output end of the reducer and the stirring transmission rod 8, the stirring transmission rod 8 can be rotated. When the stirring transmission rod 8 rotates, through the connection between the clamp 81 and the stirring transmission rod 8, several stirring flat steels 84 installed on both sides of the connecting rod 82 can rotate with the rotation of the stirring transmission rod 8. When the stirring flat steels 84 rotate, the centrifugal force will push the bubbles generated by the stirring towards the outer edge of the stirring flat steels 84. At this time, the bubbles will repeatedly collide with the surface of the stirring flat steels 84. The stirring flat steels 84, which are arranged horizontally and in a cross shape, can increase the shear force during the stirring process, making it easier to break the bubbles in the liquid. The shear force generated will break the bubbles on the surface of the liquid. As the blades rotate, the bubbles break and the gas escapes into the air, thus completing the defoaming stirring.

[0043] Step 2: When the user needs to adapt and stir chemical raw materials in chemical tank bodies 11 of different sizes, the chemical tank body 11 is disassembled and assembled on the chemical stirring table 10, and the height adjustment component 9 is adjusted at the same time. At this time, the height adjustment component 9 can adjust its stirring height, so as to adapt to chemical tank bodies 11 of different sizes and stir the chemical raw materials inside. During the adjustment of the height adjustment component 9, the user connects the reciprocating motor 98 to the power supply. When the reciprocating motor 98 is running, it can drive the threaded screw 93 to rotate. When the threaded screw 93 rotates, it is laterally limited by the two side rods 97 on the slider seat 95. At this time, the screw nut 94 engaged on the outside of the threaded screw 93 will drive the slider seat 95 and the connecting plate 96 to move in a reciprocating linear motion along the stroke range of the threaded screw 93. When the connecting plate 96 moves, the moving plate 5 installed on the side of the connecting plate 96 can drive the support plate 6, motor 7, reducer and stirring transmission rod 8 to adjust the overall height.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
