Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical technology, specifically to a horizontal mixer. Background Technology
[0002] In chemical production, different raw materials and additives are mixed. Horizontal mixers are often used for this purpose. They can mix different types of materials in a certain proportion, so that they can fully contact and be evenly distributed, thereby ensuring the stability of the finished product's performance.
[0003] Existing mixers have a simple structure, typically consisting of a mixer body, stirring blades, and a drive motor. However, in actual production use, the following problems exist: 1. Excessive tangential flow causes the material to form large eddies within the container, resulting in suboptimal mixing. 2. Different materials are prone to stratification, creating dead zones within the mixer body. This causes material to stagnate in these areas, preventing thorough mixing and affecting the quality of the final product. Utility Model Content
[0004] This invention aims to solve the technical problem that existing mixers have strong tangential flow during mixing, which easily forms large vortices and obvious stratification, resulting in uneven mixing. The purpose is to provide a horizontal mixer that can reduce the tangential flow of materials, effectively reduce the vortices generated during the mixing process, and achieve full mixing of materials at different depths and positions, thereby improving the uniformity of mixing.
[0005] This utility model is achieved through the following technical solution:
[0006] A horizontal mixer includes a mixer body, a drive mechanism, a central rotating shaft, a baffle, and a flow guide groove;
[0007] The central rotating shaft is equipped with propeller blades and is driven to rotate by a drive mechanism. The baffles and guide grooves are evenly arranged on the inner wall of the mixer. The guide grooves are located between two adjacent baffles and are recessed into the inner wall of the mixer.
[0008] Furthermore, a guide plate is also provided inside the flow-guiding groove.
[0009] Furthermore, the deflector includes long deflectors and short deflectors arranged in an alternating pattern.
[0010] Furthermore, both the long guide plate and the short guide plate are perpendicular to the tangent at the location of the inner wall of the guide groove.
[0011] Furthermore, the propeller blades include a first propeller blade and a second propeller blade with different diameters, and the first propeller blade and the second propeller blade are respectively disposed on both sides of the central shaft.
[0012] Furthermore, the first and second propeller blades are connected to the central shaft via a connecting rod.
[0013] Furthermore, the driving mechanism is a planetary gear drive mechanism.
[0014] Furthermore, the planetary gear drive mechanism includes a ring gear, planetary gears, a sun gear, a motor, and a reducer. The planetary gears are located between the ring gear and the sun gear, and are meshed with both the ring gear and the sun gear. The sun gear is connected to the motor and the reducer.
[0015] Furthermore, the sun gear is connected to the central shaft.
[0016] Furthermore, the gear ring is connected to the mixer body.
[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0018] 1. This utility model, by uniformly arranging baffles on the inner wall of the mixer and setting guide grooves between adjacent baffles, achieves the following: First, the baffles weaken tangential flow, change the direction of the fluid, and enhance radial and axial flow, generating turbulence during mixing and preventing vortices. The baffles can be installed vertically or at an angle, and can also divide the interior into multiple small areas, reducing the formation of eddies. Second, by setting guide grooves, when eddies pass through the guide grooves, some material will flow along the guide grooves on the inner wall. Due to the concave shape of the guide grooves, the eddies of material flowing within the guide grooves will disappear. Third, after the mixed material exits through the guide grooves, it will encounter the baffles again, and the tangential flow will be weakened once more by the action of the baffles. The baffles and guide grooves are arranged alternately, and the two can synergistically enhance the weakening effect on tangential flow, reduce the generation of eddies, and ensure that the material is fully mixed in the mixer, improving the uniformity of mixing.
[0019] 2. This utility model sets the propeller blades to have different diameters. When they rotate around the central axis, the diameters of the trailing circles of the two propeller blades are different. This allows the materials at different depths and positions inside the machine to be fully mixed, ensuring the uniformity of the material mixing and leaving no dead corners. It can effectively avoid blind spots in the mixing of materials, allowing the materials to be fully mixed in the mixer and improving the uniformity of mixing.
[0020] 3. This utility model uses planetary gear transmission to enable the mixer body to rotate in opposite directions. The mixer body and the propeller blades form a stirring convection, which can reduce the tangential flow of the fluid during the stirring process and effectively weaken the vortex generated during the stirring process, thereby achieving a highly efficient mixing process.

[0033] Example
[0034] This embodiment provides a horizontal mixer, such as Figures 1-4 As shown, it includes a mixer body 1, a drive mechanism 2, a central rotating shaft 4, a baffle 3, and a flow guide groove 8;
[0035] The central rotating shaft 4 is equipped with propeller blades, and the central rotating shaft 4 is driven to rotate by the driving mechanism 2. The baffles 3 and the flow guide grooves 8 are evenly arranged on the inner wall of the mixer body 1. The flow guide grooves 8 are located between two adjacent baffles 3 and are recessed into the inner wall of the mixer body 1.
[0036] When the viscosity of the material being mixed in an existing horizontal mixer is low, the fluid can easily form a tangential flow under the drive of the agitator, which may generate vortices. Secondly, when the speed of the agitator is too high, the fluid will also surge towards the machine wall under the action of centrifugal force, and the central liquid level will drop, thus forming vortices. If the vortex is too large or too deep, it may cause the material to be over-mixed in a local area while other areas are under-mixed, reducing the mixing effect.
[0037] Based on this, the present invention provides baffles 3 evenly arranged on the inner wall of the mixer body 1, and guide grooves 8 between adjacent baffles 3. Firstly, the baffles 3 can weaken tangential flow, change the direction of the fluid, strengthen radial and axial flow, generate turbulence during mixing, and prevent vortex formation. The baffles 3 can be installed vertically or at an angle. The baffles 3 can also divide the interior into multiple small areas, reducing the formation of eddies. Secondly, by setting the guide grooves 8, when eddies pass through the guide grooves 8, some materials will flow along the guide grooves 8 on the inner wall. Since the guide grooves 8 are concave, the eddies of materials flowing in the guide grooves 8 will disappear. Thirdly, after the mixed materials exit through the guide grooves 8, they will encounter the baffles 3 again, and the tangential flow will be weakened again by the action of the baffles 3. The baffles 3 and guide grooves 8 are set alternately, and the two can synergistically enhance the weakening effect on tangential flow, reduce the generation of eddies, and make the materials fully mixed in the mixer, improving the mixing uniformity.
[0038] like Figure 3 and 4 As shown, a guide plate is also provided inside the flow guiding groove 8. By further providing a guide plate inside the flow guiding groove 8, the flow direction of the fluid inside the flow guiding groove 8 can be disturbed, so that turbulence is generated during stirring, and the generation of vortices is further reduced.
[0039] Specifically, the guide plate includes staggered long guide plates 9 and short guide plates 10, both of which are perpendicular to the tangent at the location of the inner wall of the guide groove 8. The staggered arrangement of the long guide plates 9 and short guide plates 10 can better turbulentize the fluid in the guide groove 8, making it easier for the material to generate turbulence during stirring, thereby effectively reducing the generation of vortices.
[0040] like Figure 1 As shown, the propeller blades include a first propeller blade 5 and a second propeller blade 6 with different diameters. The first propeller blade 5 and the second propeller blade 6 are respectively disposed on both sides of the central rotating shaft 4. The first propeller blade 5 and the second propeller blade 6 are connected to the central rotating shaft 4 through a connecting rod 7.
[0041] By setting the propeller blades to have different diameters, when they rotate around the central shaft 4, the diameters of the trailing circles of the two propeller blades are different. This allows for the thorough mixing of materials at different depths and positions inside the machine, ensuring the uniformity of material mixing and eliminating dead zones. It effectively avoids blind spots in material mixing, allowing the materials to be fully mixed in the mixer and improving the uniformity of mixing.
[0042] like Figure 2 As shown, the drive mechanism 2 is a planetary gear drive mechanism.
[0043] Specifically, the planetary gear drive mechanism includes a ring gear 201, planetary gears 202, a sun gear 203, and a motor and reducer device 204. The planetary gear 202 is located between the ring gear 201 and the sun gear 203, and the planetary gear 202 is meshed with the ring gear 201 and the sun gear 203 respectively. The sun gear 203 is connected to the motor and reducer device 204 and is connected to the central rotating shaft 4. The ring gear 201 is connected to the mixer body 1.
[0044] The motor and reducer device 204 serves as the power source. The output shaft of the reducer is connected to the sun gear 203 in the planetary gear drive mechanism. The sun gear 203 is connected to the central rotating shaft 4. The gear ring 201 of the planetary gear drive mechanism is connected to the mixer body 1. When the motor and reducer device 204 drives the sun gear 203 to rotate, the first propeller blade 5 and the second propeller blade 6 rotate simultaneously. Since the gear ring 201 is connected to the mixer body 1, the mixer body 1 can rotate in the opposite direction through the transmission of the planetary gear 202. This allows the mixer body 1 and the propeller blades to form a stirring convection, which can reduce the tangential flow of the fluid during the stirring process and effectively weaken the vortex generated during the stirring process, thereby achieving a highly efficient mixing process.
[0045] It should be noted that a discharge port is also provided on the body 1 of the mixer. When discharging, the discharge port is located at the bottom and is equipped with a simple switch, which can ensure that all materials can be poured out, reducing material residue.
[0046] Finally, it should be noted that the above specific embodiments are only used to describe the purpose, technical solution, and beneficial effects of this utility model in detail. It should be understood that the above description is only a specific implementation of this utility model and is not intended to limit the protection scope of this utility model. Although this utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or improvements can be made to some or all of the technical features. These modifications, equivalent substitutions, and improvements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
