Description

Technical Field

[0001] The utility model relates to the technical field of material dispersing devices, in particular to a high-efficiency and low-energy-consumption material dispersing device. Background Art

[0002] Disperser is a kind of mixer in a broad sense. Since the use of high-speed agitators (such as disc sawtooth agitators) can form strong turbulence locally, it usually has a strong dispersing and emulsifying effect on the material. When using a toothed disc high-speed disperser for mixing and dispersing, the high-speed disperser is required to play two functions of shearing dispersion and stirring mixing.

[0003] At present, in high-viscosity and large-scale production scenarios, there are high requirements for the power of the high-speed disperser. When using a traditional high-speed disperser to disperse materials, the dispersion effect can only be improved by increasing the speed. As the viscosity and capacity of the material increase, the energy consumption will increase significantly. In addition, the high-speed disperser mainly provides shear force to the material, and there will be problems such as slow speed and uneven upper and lower layers during mixing. In view of this, we propose a high-efficiency and low-energy material dispersion device. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] See also Figure 1-Figure 3 , This embodiment provides a high-efficiency and low-energy-consumption material dispersing device, including a pull cylinder 1 for containing materials;

[0032] A stirring mechanism 2, used to provide high-speed shear force to the material;

[0033] Dispersing mechanism 3, used to provide low-speed shear force to the material;

[0034] A bubbling mechanism 4, used to provide vertical thrust to the material; and

[0035] A support frame 5, used to provide support for the stirring mechanism 2 and the dispersing mechanism 3;

[0036] The bubbling mechanism 4 includes an air inlet pipe 401, one end of which is connected to a shunt pipe 402, and at least two ventilation pipes 403 are connected to the shunt pipe 402. The end of the ventilation pipe 403 away from the shunt pipe 402 passes through the bottom end of the pull cylinder 1 and is connected to the inside of the pull cylinder 1, which is used to bubble into the inside of the pull cylinder 1. The bubbling at the bottom can promote the upward and downward flow of materials, solving the problem of uneven upper and lower layers. The end of the air inlet pipe 401 away from the shunt pipe 402 is connected to an air compressor (not shown in the figure) to provide compressed gas to the mechanism. The air inlet pipe 401 is connected to a pressure reducing valve 404 and a ball valve 405, wherein the ball valve 405 is used to control the flow of compressed gas, and the pressure reducing valve 404 is used to reduce the pressure of compressed air to keep the air pressure stable.

[0037] Please combine Figure 2 and Figure 3 As shown, the stirring mechanism 2 includes a stirring motor 201, and the output end of the stirring motor 201 is connected to the stirring shaft 203 through a reducer 202. The reducer 202 is fixedly mounted on the support frame 5 for reducing the rotation speed and increasing the torque. The bottom end of the stirring shaft 203 is fixedly connected to a stirring frame 204. The stirring frame 204 and the stirring shaft 203 form an anchor agitator for mixing the materials in the pull cylinder 1 at a low speed.

[0038] Please continue reading Figure 2 and Figure 3 The dispersion mechanism 3 includes a dispersion shaft 301, and a toothed dispersion disc 302 is fixedly connected to the bottom end of the dispersion shaft 301. The toothed dispersion disc 302 is located in the area between the stirring shaft 203 and the stirring frame 204. After the toothed dispersion disc 302 rotates at a high speed, a local turbulent zone can be formed in the area surrounded by the anchor agitator, and the local material can be sheared and crushed at a high speed, while promoting rapid dispersion and mixing of the material.

[0039] Combination Figure 1 and Figure 2 As shown, the high-efficiency and low-energy material dispersing device also includes a fixed plate 6, one end of which is fixedly connected to the support frame 5, and a dispersing motor 7 is installed on the fixed plate 6. The output end of the dispersing motor 7 is connected to one end of the dispersing shaft 301 for controlling the high-speed rotation of the toothed dispersing disc 302.

[0040] According to the calculation of the total actual operating current under the same scenario: in the application scenario of a 2000L cylinder carrying 3000kg of materials, the use of 15kw low-speed mixing + 7.5kw dispersion + 2.2kw air compressor can be equivalent to the effect of 30kw double-axis high-speed dispersion. The total power of a single machine is significantly reduced, and the total energy consumption of the equipment is reduced.

[0041] In addition, the stirring + dispersion + bubbling mode is used to promote the horizontal movement of materials through stirring, and the vertical movement of materials through bubbling. The original 30kw dual-axis dispersion requires 60-120 minutes of dispersion, and powder will accumulate at the bottom, requiring manual processing. The dispersion + stirring + bubbling mode can achieve no powder accumulation at the bottom and no powder floating on the surface in 45-60 minutes, and the dispersion effect is significantly improved.

[0042] The stirring motor 201 controls the anchor stirrer to stir the periphery of the material at a low speed, and the dispersion motor 7 controls the toothed dispersion disk 302 to disperse the intermediate material at a high speed. When used, the stirring and dispersion speeds can be adjusted respectively according to the form and actual viscosity of the material to achieve the best mixing effect and the lowest energy consumption, and it has a good effect on the dispersion and mixing of medium and high viscosity and large-capacity materials.

[0043] When in use, put the material to be dispersed in the cylinder 1, turn on the stirring motor 201, and the stirring motor 201 drives the anchor stirrer to rotate through the reducer 202, providing low-speed shear force to the material in the cylinder 1, so that the material starts to circulate. Turn on the dispersion motor 7, and the dispersion motor 7 drives the toothed dispersion disc 302 to rotate at high speed through the dispersion shaft 301, providing high-speed shear force to the material, and promoting rapid dispersion and mixing of the material. Then open the ball valve 405, and the compressed gas enters the diversion pipe 402 after passing through the pressure reducing valve 404, and enters the ventilation pipe 403 after diversion, and then enters the cylinder 1, promoting the up and down flow of the material, so that the fluid in the cylinder can achieve dead-angle circulation and shearing.

[0044] Embodiment 2

[0045] See also Figure 4-Figure 6 , This embodiment provides a high-efficiency and low-energy-consumption material dispersing device, including a pull cylinder 1 for containing materials;

[0046] A stirring mechanism 2, used to provide high-speed shear force to the material;

[0047] Dispersing mechanism 3, used to provide low-speed shear force to the material;

[0048] A bubbling mechanism 4, used to provide vertical thrust to the material; and

[0049] A support frame 5, used to provide support for the stirring mechanism 2 and the dispersing mechanism 3;

[0050] The bubbling mechanism 4 includes an air inlet pipe 401, one end of which is connected to a shunt pipe 402, and at least two ventilation pipes 403 are connected to the shunt pipe 402. The end of the ventilation pipe 403 away from the shunt pipe 402 passes through the bottom end of the pull cylinder 1 and is connected to the inside of the pull cylinder 1, which is used to bubble into the inside of the pull cylinder 1. The bubbling at the bottom can promote the upward and downward flow of materials, solving the problem of uneven upper and lower layers. The end of the air inlet pipe 401 away from the shunt pipe 402 is connected to an air compressor (not shown in the figure) to provide compressed gas to the mechanism. The air inlet pipe 401 is connected to a pressure reducing valve 404 and a ball valve 405, wherein the ball valve 405 is used to control the flow of compressed gas, and the pressure reducing valve 404 is used to reduce the pressure of compressed air to keep the air pressure stable.

[0051] Please combine Figure 2 and Figure 3 As shown, the stirring mechanism 2 includes a stirring motor 201, and the output end of the stirring motor 201 is connected to the stirring shaft 203 through a reducer 202. The reducer 202 is fixedly mounted on the support frame 5 for reducing the rotation speed and increasing the torque. The bottom end of the stirring shaft 203 is fixedly connected to a stirring frame 204. The stirring frame 204 and the stirring shaft 203 form an anchor agitator for mixing the materials in the pull cylinder 1 at a low speed.

[0052] Please continue reading Figure 2 and Figure 3 The dispersion mechanism 3 includes a dispersion shaft 301, and a toothed dispersion disc 302 is fixedly connected to the bottom end of the dispersion shaft 301. The toothed dispersion disc 302 is located in the area between the stirring shaft 203 and the stirring frame 204. After the toothed dispersion disc 302 rotates at a high speed, a local turbulent zone can be formed in the area surrounded by the anchor agitator, and the local material can be sheared and crushed at a high speed, while promoting rapid dispersion and mixing of the material.

[0053] In this embodiment, the high-efficiency and low-energy consumption material dispersing device further includes a transmission mechanism 8 .

[0054] Specifically, the transmission mechanism 8 includes a connecting plate 801, one end of which is fixedly connected to the outer peripheral wall of the stirring shaft 203, and the inner wall of the connecting plate 801 is rotatably connected to the outer peripheral wall of the dispersion shaft 301 through a bearing. When the stirring shaft 203 rotates, the dispersion shaft 301 can be driven by the connecting plate 801 to make a circular motion around the stirring shaft 203, thereby changing the working position of the toothed dispersion disc 302.

[0055] Please combine Figure 5 and Figure 6 As shown, the transmission mechanism 8 also includes a pinion 802, which is fixedly connected to the top of the dispersion shaft 301, and a fixed gear 803 is meshed on the surface of the pinion 802. A sleeve 804 is fixedly connected to the axis of the fixed gear 803, and the sleeve 804 is sleeved on the stirring shaft 203, and the stirring shaft 203 can rotate inside the sleeve 804.

[0056] It also includes a fixing frame 9, one end of which is fixedly connected to the support frame 5, and the other end is fixedly connected to the sleeve 804, so that the sleeve 804 can be fixed. When the dispersion shaft 301 makes a circular motion around the stirring shaft 203, the small gear 802 at the top of the dispersion shaft 301 will roll around the outer periphery of the fixed gear 803, thereby driving the dispersion shaft 301 to rotate, so that the toothed dispersion disk 302 rotates automatically to disperse the material in the anchor agitator.

[0057] The difference between the second embodiment and the first embodiment is that the space occupied by the equipment is reduced and the bearing pressure of the support frame 5 is reduced. The stirring motor 201 drives the stirring frame 204 and the toothed dispersion disc 302 to rotate at the same time, and the diameter ratio of the pinion 802 and the fixed gear 803 is designed so that the rotation speed of the toothed dispersion disc 302 is higher than the rotation speed of the stirring frame 204, so as to achieve the purpose of matching the peripheral low-speed stirring with the local high-speed dispersion. In addition, by setting the connecting plate 801, the toothed dispersion disc 302 can move circumferentially around the center of the pull cylinder 1 while rotating, constantly changing the dispersion area, ensuring the uniformity of material mixing, and having a good effect on the mixing of medium and low viscosity and small volume materials.

[0058] When in use, the material to be dispersed is placed in the pull cylinder 1, and the stirring motor 201 is turned on. The stirring motor 201 drives the anchor agitator to rotate through the reducer 202, providing low-speed shear force to the material in the pull cylinder 1, so that the material begins to circulate. The stirring shaft 203 of the anchor agitator drives the dispersion shaft 301 to make a circular motion around the stirring shaft 203 through the connecting plate 801. The small gear 802 at the top of the dispersion shaft 301 will roll around the outer periphery of the fixed gear 803, thereby driving the dispersion shaft 301 to rotate, so that the toothed dispersion disk 302 rotates automatically to disperse the material in the anchor agitator. At this time, the bubbling mechanism 4 continuously injects compressed gas into the pull cylinder 1 to promote the upward and downward flow of logistics and realize the circulation of the fluid in the cylinder without dead ends.
