Abstract
Description
Technical Field
[0001] This utility model relates to the field of material mixing technology, and in particular to a reciprocating vertical high-speed mixer. Background Technology
[0002] In industries such as chemical, pharmaceutical, and food processing, high-speed mixers are commonly used for mixing, dispersing, and homogenizing materials. Existing vertical high-speed mixers typically rely solely on a motor to drive the mixing shaft in a single direction of rotation, and the angle of the mixing blades is often fixed.
[0003] This single-dimensional stirring method has the following drawbacks: First, the material can only form a single vortex in the container, which can easily create dead zones at the bottom or edge of the container, resulting in uneven mixing. Second, the fixed blade angle cannot adapt to the material requirements of different viscosities or different mixing stages. For high-viscosity materials, it can easily lead to motor overload or low mixing efficiency. Utility Model Content
[0004] Therefore, it is necessary to provide a reciprocating vertical high-speed mixer to address the above-mentioned technical problems, so as to realize that the mixing shaft can rotate at high speed and move up and down reciprocally, and automatically change the angle of the mixing blades during the process to reduce the mixing dead angle.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A reciprocating vertical high-speed mixer, comprising:
[0007] A container used to hold materials to be mixed;
[0008] A stirring mechanism includes a splined shaft that can slide up and down relative to a container and a stirring shaft fixedly connected to the bottom of the splined shaft. The outer wall of the stirring shaft is rotatably connected to a stirring blade, which is rotatably engaged with the stirring shaft via a telescopic linkage assembly.
[0009] A drive component, which is disposed on the container, is used to drive the spline shaft to rotate and thus agitate the material;
[0010] A reciprocating mechanism, installed on top of the container, is used to drive the splined shaft to reciprocate up and down inside the container;
[0011] The stirring angle adjustment mechanism is installed on top of the reciprocating mechanism and controls the stirring blades to switch between the first angle and the second angle during the reciprocating motion of the spline shaft.
[0012] Furthermore, the container includes a can and a lid, the lid being snapped into and fixed to the can by bolts hinged to the can.
[0013] Furthermore, the driving component includes a drive motor, the output end of which is fixedly connected to a worm gear, the outer wall of which is meshed with a worm wheel, the middle of which is fixedly connected to a spline sleeve, and the spline shaft and the spline sleeve are in sliding fit.
[0014] Furthermore, the stirring blade includes a fixed part rotatably mounted on the outer wall of the stirring shaft via a bearing and a blade part detachably mounted on the fixed part via bolts, wherein the side wall of the fixed part extends outward to form a rotating part.
[0015] Furthermore, the telescopic linkage assembly includes a ring frame fixedly connected to the outer wall of the stirring shaft, and a telescopic air rod is rotatably connected between the ring frame and the rotating part via a universal joint, the telescopic air rod being connected to the ring frame via a conduit.
[0016] Furthermore, the reciprocating mechanism includes a magnet block fixedly installed on the top of the spline shaft and an electromagnet located above the magnet block. A spring is fixedly connected to the top of the magnet block, and the spring provides elastic potential energy for the spline shaft to move downward. When the electromagnet is energized, it attracts the magnet block, causing the spline shaft to slide upward.
[0017] Furthermore, the stirring angle adjustment mechanism includes a piston tube and a piston rod fixedly connected to the top of the spline shaft. The top of the piston rod is rotatably connected to a piston via a bearing, and the piston is sealed to the piston tube.
[0018] Furthermore, the piston rod, spline shaft, stirring shaft, and ring frame are connected by an air passage to provide adjustable air pressure for the telescopic air rod.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] This utility model provides a reciprocating vertical high-speed mixer, which achieves high-speed rotation through a drive component and reciprocating motion up and down through the cooperation of electromagnetic and spring components. It breaks the single two-dimensional flow field of traditional mixers, causing strong convection and shearing of materials in each layer of the container. The mechanical energy of the reciprocating motion of the spline shaft is cleverly converted into changes in air pressure in the air path, which in turn drives the telescopic air rod to change the angle of the mixing blades. During the upward and downward strokes, the blades present different angles of attack, which can effectively tear the materials and squeeze and tumble them. Attached Figure Description

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0034] Example 1
[0035] Please refer to Figure 1-6 A reciprocating vertical high-speed mixer, comprising:
[0036] Container 1 is used to contain the material to be stirred. Container 1 includes a tank body 11 and a cover 12. The cover 12 is fixed to the tank body 11 by bolt clips 13 hinged to the tank body 11. The bolt clips 13 include a bracket hinged to the tank body 11. A locking bolt is threaded onto the bracket. The operator can unlatch the locking bolt, open the cover 12, add the material to be stirred into the tank body 11, and then close the cover 12 and tighten the bolt clips 13 to fix it.
[0037] The stirring mechanism 2 includes a splined shaft 21 that can slide up and down relative to the container 1 and a stirring shaft 22 fixedly connected to the bottom of the splined shaft 21. The outer wall of the stirring shaft 22 is rotatably connected to a stirring blade 23, and the stirring blade 23 is rotatably engaged with the stirring shaft 22 through a telescopic connecting rod assembly 24.
[0038] The driving component 3 is mounted on the container 1 and is used to drive the spline shaft 21 to rotate to achieve material stirring.
[0039] The reciprocating mechanism 4 is installed on the top of the container 1 to drive the spline shaft 21 to reciprocate up and down inside the container 1.
[0040] The stirring angle adjustment mechanism 5 is installed on top of the reciprocating mechanism 4 and controls the stirring blade 23 to switch between the first angle and the second angle when the spline shaft 21 reciprocates.
[0041] Example 2
[0042] The reciprocating vertical high-speed mixer provided in Embodiment 1 is further optimized. Specifically, the drive component 3 includes a drive motor 31, the output end of the drive motor 31 is fixedly connected to a worm 32, the outer wall of the worm 32 is meshed with a worm wheel 33, the middle part of the worm wheel 33 is fixedly connected to a spline sleeve 34, and the spline shaft 21 is slidably engaged with the spline sleeve 34. The worm wheel 33 and the worm 32 achieve speed reduction and torque increase. At the same time, the engagement between the spline sleeve 34 and the spline shaft 21 transmits torque and allows axial sliding.
[0043] The spline shaft 21 is inserted into the spline sleeve 34 from bottom to top and slides with the spline sleeve 34 through the keyway. When the drive motor 31 is started, the power is transmitted to the spline sleeve 34 through the worm 32 and worm wheel 33, which drives the spline shaft 21 and the bottom stirring shaft 22 to rotate at high speed. At the same time, the spline shaft 21 can slide freely up and down in the spline sleeve 34 without interfering with each other.
[0044] Example 3
[0045] The reciprocating vertical high-speed mixer provided in Embodiment 1 or 2 is further optimized. The mixing blade 23 includes a fixed part 231 that is rotatably mounted on the outer wall of the mixing shaft 22 via a bearing and a blade part 232 that is detachably mounted on the fixed part 231 via bolts. The side wall of the fixed part 231 extends outward to form a rotating part 233. The detachable blade part 232 is easy to replace or clean after wear.
[0046] The telescopic linkage assembly 24 includes a ring frame 241 fixedly connected to the outer wall of the stirring shaft 22. The ring frame 241 and the rotating part 233 are rotatably connected by a telescopic air rod 242 through a universal joint. The telescopic air rod 242 is connected to the ring frame 241 through a conduit.
[0047] When the telescopic air rod 242 extends, it pushes the rotating part 233, forcing the stirring blade 23 to rotate around the bearing to a second angle (such as a small tilt angle); when the air rod retracts, the stirring blade 23 returns to the first angle (such as a large tilt angle) due to the resistance of the liquid flow or the action of the return spring.
[0048] Example 4
[0049] The reciprocating vertical high-speed mixer provided in Embodiment 3 is further optimized. The reciprocating mechanism 4 includes a magnet block 41 fixedly installed on the top of the spline shaft 21 and an electromagnet 42 located above the magnet block 41. A spring 43 is fixedly connected to the top of the magnet block 41. The spring 43 provides elastic potential energy for the spline shaft 21 to move downward. When the electromagnet 42 is energized, it attracts the magnet block 41, causing the spline shaft 21 to slide upward.
[0050] Under normal conditions, the spring force of spring 43 keeps spline shaft 21 in the lowest position. When a positive pulse current is applied to electromagnet 42, the magnetic force overcomes the spring force and attracts magnet block 41, causing spline shaft 21 to slide upward. After the power is turned off, spring 43 releases potential energy to reset and slide downward, thus realizing up-and-down reciprocating motion.
[0051] The stirring angle adjustment mechanism 5 includes a piston tube 51 and a piston rod 52 fixedly connected to the top of the spline shaft 21. The top of the piston rod 52 is rotatably connected to a piston 53 via a bearing, and the piston 53 is sealed to the piston tube 51.
[0052] The piston rod 52, spline shaft 21, stirring shaft 22 and ring frame 241 are connected by an air passage to provide adjustable air pressure for the telescopic air rod 242. The vertical displacement of the spline shaft 21 is used directly as the power source for the air pump, without the need for an additional air pump.
[0053] To further improve the sensitivity and adjustable range of angle adjustment, a small accumulator and a precision pressure regulating valve can be added to the connecting air circuit. The accumulator is used to smooth pressure fluctuations and make the operation more stable. The pressure regulating valve can be adjusted manually or through the controller to set the system's base pressure, thereby changing the position of the swing midpoint of the stirring blade between two extreme angles to adapt to materials of different viscosities.
[0054] The following is the usage process of the reciprocating vertical high-speed mixer provided by this utility model: Start the drive motor 31. After the motor is reduced in speed by the worm gear 33 and the worm 32, it drives the spline shaft 21 and the stirring shaft 22 to drive the stirring blade 23 to start rotating at high speed, and initially disperses the material.
[0055] The electrical control system of the reciprocating mechanism 4 is activated, causing the electromagnet 42 to be energized and de-energized according to the set frequency. When the electromagnet 42 is energized, the magnet block 41 attracts the spline shaft 21 to move upward. During this process, the piston rod 52 moves upward, and the piston 53 compresses the air upward in the piston tube 51, causing positive pressure to be generated in the internal air passage. The telescopic air rod 242 extends, and the stirring blade 23 is converted to the second angle (such as tending to be horizontal) under the resistance of the material and the traction of the connecting rod, and performs transverse shearing on the material.
[0056] When the electromagnet 42 is de-energized, the spring 43 pushes the spline shaft 21 to move downwards rapidly; at this time, the piston 53 draws air downwards in the piston tube 51, causing negative pressure to be generated in the internal air passage, the telescopic rod 242 contracts, and pushes the rotating part 233 to flip the stirring blade 23 to the first angle (such as a large downward pressure angle), which, together with the downward displacement of the shaft, produces a strong downward squeezing and tumbling effect on the material at the bottom of the tank.
