Description

Technical Field

[0001] The utility model relates to the technical field of emulsification devices, in particular to an ultra-long emulsification device. Background Art

[0002] In recent years, the development of stirred tank equipment in the new energy battery industry in my country has accelerated.

[0003] The room for improvement of equipment will be further improved, and at the same time, it is facing the severe challenge of meeting the requirements of rational use of resources, energy saving and consumption reduction, and environmental protection. While the mixing equipment is subject to the scale economy and variety diversification of the equipment, the output is also increasing. In order to meet the production needs, the volume of the mixing kettle has been increased on the original basis, and the corresponding emulsifying paddle also needs to be larger and longer.

[0004] The existing emulsifier is usually directly connected to the motor or has three polished rods as the extension end to fix the stator of the emulsifier, and the rotor is fixed inside the stator by a rotating shaft. Due to the increase in the volume of the existing tank, the three fixed polished rods are extended too long. Due to the too long cantilever, the rotor will drive the water flow to rotate during the rotation process, forming a torque on the entire emulsifier. During operation, it is easy to cause the three polished rods to deform and the bolts to loosen, which eventually causes the stator and rotor to collide, and the entire emulsifier is completely scrapped. In addition, the existing agitator is prone to material contamination due to long-term material accumulation. Utility Model Content

[0005] The purpose of the utility model is to provide an extra-long emulsifying device to solve the problems raised in the above-mentioned background technology.

[0024] In order to make the above and / or other purposes, effects, and features of the present invention more obvious and easy to understand, the following is a detailed description of the preferred implementation modes:

[0025] See also Figure 1 , Figure 1 As one embodiment of the utility model, the utility model provides an extra-long emulsifying device, wherein the utility model has four annular waist holes K evenly arranged at the bottom of the stator fixing seat 6, which can cool the sliding bearing 7 during stirring to avoid excessive temperature caused by high-speed rotation; in addition, when stopping, the slurry can be completely discharged through the waist holes K to avoid the slurry remaining in the emulsifying head and prevent material contamination caused by long-term accumulation of materials.

[0026] See also Figure 2 , Figure 2 The structure diagram of the utility model includes: a transmission device T; a stator fixing seat 6, which is a tubular structure, the transmission device T is passed through the central axis of the stator fixing seat 6, and the tubular structure can better transmit torque, reduce the relative movement of the stator 8 and the rotor 9 during operation, so as to increase the service life of the emulsifier; a stator 8, fixed to one end of the stator fixing seat 6 close to the waist hole K; and a rotor 9, fixed to one end of the transmission device T close to the waist hole K. The transmission device T includes: a transmission shaft 5; a rotating shaft 3, one end of the rotating shaft 3 is fixed to one end of the transmission shaft 5 away from the waist hole K by a coupling 4; and a sliding bearing 7, which is arranged at one end of the transmission shaft 5 opposite to the rotating shaft 3. The emulsifier further includes a mounting seat 2, which is fixed to one end of the stator fixing seat 6 away from the waist hole K by a plurality of first fixing members 21. The emulsifying device further includes a motor 1 , which is fixed to one end of the mounting base 2 away from the stator fixing base 6 by a plurality of second fixing members 22 and connected to the rotating shaft 3 .

[0027] See also Figure 3 , Figure 3 for Figure 2 In the enlarged view at point A, the bottom diameter of the transmission shaft 5 is slightly shortened to set and limit the position of the sliding bearing 7. The stator 8 is set outside the sliding bearing 7, and the stator 8 is fixed to the stator fixing seat 6. The rotor 9 is fixed to the transmission shaft 5 at the bottom.

[0028] Specifically, the utility model provides an emulsifying device, which comprises a motor 1 from top to bottom,

[0029] The mounting base 2 is fixed to the motor 1 by bolts, the rotating shaft 3 is connected to the motor 1, and the transmission shaft 5 is fixed to the rotating shaft 3 by a coupling 4. A stator fixing base 6 is provided on the outside of the transmission shaft 5, and the transmission shaft 5 passes through the stator fixing base 6. The stator fixing base 6 is fixed to the mounting base 2 by bolts, the stator 8 is fixed to the stator fixing base 6, the rotor 9 is fixed to the transmission shaft 5, and the sliding bearing 7 is arranged on the transmission shaft 5 and is located between the stator 8 and the transmission shaft 5.

[0030] The specific working principle is that the motor 1 drives the rotating shaft 3 in the mounting seat 2 to rotate, and the rotating shaft 3 transmits the torque to the transmission shaft 5 through the coupling 4, and the transmission shaft 5 drives the rotor 9 to rotate. The stator 8 is fixed on the stator fixing seat 6, and the stator fixing seat 6 is fixed on the mounting seat 2. The rotor 9 rotates in the stator 8, driving the liquid to rotate at high speed and discharge from the waist hole K of the stator 8. Since the stator 8 is stationary, a liquid speed difference will be formed between the rotor 9 and the stator 8. Through this speed difference, a shear force will be formed on the material molecules, and finally a crushing effect is achieved. The powder particles in the liquid are crushed by mutual extrusion, and finally the liquid containing the powder forms an emulsion.

[0031] See also Figure 4 , Figure 4 for Figure 2 The enlarged view at point B includes a bearing 10, which is arranged between the mounting seat 2 and the rotating shaft 3; a bearing pressure cover 11, which is arranged on a side of the bearing 10 away from the stator fixing seat 6; a nut 17, which is fixed to the rotating shaft 3 and arranged on a side of the bearing 10 away from the bearing pressure cover 11; a bearing lower pressure cover 12, which is arranged on a side of the bearing 10 close to the stator fixing seat 6; a first O-ring 15, which is arranged between the bearing lower pressure cover 12 and the mounting seat 2; a skeleton oil seal 13, which is arranged between the rotating shaft 3 and the bearing lower pressure cover 12; an oil seal protective sleeve 14, which is arranged between the rotating shaft 3 and the skeleton oil seal 13; a second O-ring 16, which is arranged between the rotating shaft 3 and the oil seal protective sleeve 14.

[0032] Specifically, in order to prevent metal foreign matter from falling and contaminating the slurry and to prevent the slurry from entering the bearing 10 and causing the bearing 10 to wear, a skeleton oil seal 13 and two O-rings (15, 16) are provided, wherein:

[0033] The skeleton oil seal 13 is arranged below the bearing 10 to catch the metal foreign matter generated when the bearing 10 rotates, thereby preventing the metal foreign matter from contaminating the slurry; the first O-ring 15 is arranged between the bearing lower pressure cover 12 and the mounting seat 2, and the second O-ring 16 is arranged between the rotating shaft 3 and the oil seal protective sleeve 14 to prevent the slurry from entering the bearing 10 along the shaft, thereby reducing the wear of the bearing 10. In addition, a nut 17 is arranged below the bearing 10 to prevent the rotating shaft 3 from vibrating up and down during rotation, thereby causing wear of the bearing 10.

[0034] In addition, the sliding bearing 7 is made of PTFE, PA, PFA, PF, PEEK, ETFE, PCTFE, ECTFE, PVDF or FEP material, which has a self-lubricating effect. Since it is immersed in the material, the heat generated can be taken away in time, so no metal foreign matter will be generated, thereby polluting the material.
