Description

Technical Field

[0001] The utility model relates to the technical field of demulsification, in particular to a demulsification device for emulsion. Background Art

[0002] During the metal processing, emulsion is usually used for cooling. After the emulsion is recycled for many times, waste emulsion will be generated due to deterioration and invalidation. The first pretreatment method for waste emulsion is demulsification. The commonly used demulsification method at present is to add a demulsifier into the emulsion. Stirring the demulsifier and the emulsion to make them fully blend can demulsify and destabilize the emulsified oil to remove suspended solids in water.

[0003] Most of the existing stirrers for stirring demulsifiers are fixedly provided with multiple groups of stirring blades on the stirring rod. However, during actual demulsification, the amount of waste emulsion is more or less. When the amount of waste emulsion is small, its liquid level in the container is relatively low, which will cause the liquid level to be unable to cover the stirring blades. Such a stirrer rotates above the liquid level and is easy to suck external air or pollutants into the emulsion, resulting in the formation of bubbles. Excessive bubbles may interfere with the action of the demulsifier on the emulsion and affect the demulsification effect. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a demulsification device for emulsion, which solves the technical problem that the existing stirrer is easy to suck external air or pollutants into the emulsion to form bubbles when the liquid level of the emulsion is low, affecting the demulsification effect.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A demulsification device for emulsion, including a demulsification cylinder and a cylinder cover installed on the demulsification cylinder. The top of the cylinder cover is symmetrically installed with screw rods. A pressure rod is sleeved on the two screw rods. A driving shaft is rotatably installed inside the pressure rod. A threaded sleeve is threadedly connected to the outside of the driving shaft. A connecting sleeve is rotatably installed at the lower end of the threaded sleeve. The lower end of the driving shaft is fixedly connected with a chassis. A plurality of stirring mechanisms are arranged between the connecting sleeve and the chassis and are evenly distributed circumferentially along the center of the connecting sleeve.

[0006] The stirring mechanism includes a main stirring rod fixedly installed on the outside of the chassis. A secondary stirring rod is slidably installed inside the main stirring rod. A connecting rod is rotatably installed on one side of the top of the secondary stirring rod. The upper end of the connecting rod is rotatably installed on the outside of the connecting sleeve. A hanging bracket is installed at the bottom of the main stirring rod. A lower stirring rod is rotatably installed at the lower end of the hanging bracket. A transmission member is arranged between the lower stirring rod and the secondary stirring rod to drive the lower stirring rod to rotate upward and unfold as the secondary stirring rod extends.

[0007] Further, the transmission member includes a toothed plate fixedly installed at the bottom of the secondary stirring rod, a transmission gear and a driven gear rotatably installed inside the hanger. The transmission gear is arranged between the toothed plate and the driven gear, and both the toothed plate and the driven gear are engaged with the transmission gear. A rotating rod is fixedly installed inside the driven gear, and both ends of the rotating rod pass through the hanger and are fixedly connected to the lower stirring rod.

[0008] Further, a servo motor is fixedly installed at the top of the pressure rod, and a support frame for fixing the servo motor is installed on the pressure rod. The output end of the servo motor is fixedly connected to the center of the drive shaft.

[0009] Further, a telescopic spring is sleeved outside the lead screw, and the upper and lower ends of the telescopic spring are respectively fixedly installed on the cylinder cover and the pressure rod.

[0010] Further, a limit ring is threadedly connected to the outside of the lead screw, and the limit ring is arranged above the pressure rod.

[0011] Further, the demulsifying cylinder is arranged in a horn shape, and the inner diameter of the demulsifying cylinder gradually increases from top to bottom.

[0012] By means of the above technical solution, the present invention provides an emulsion demulsifying device, which has at least the following beneficial effects:

[0013] 1. By setting a stirring mechanism with adjustable height, when the liquid level in the demulsifying cylinder is relatively low, rotating the threaded sleeve can drive the secondary stirring rod to extend from the main stirring rod. At the same time, the secondary stirring rod drives the lower stirring rod to rotate upward and unfold through the transmission member, which can shorten the overall height of the stirring mechanism, so that the liquid level can completely cover the stirring mechanism. When the liquid level is relatively high, rotating the threaded sleeve in the reverse direction can, similarly, drive the secondary stirring rod to retract and the lower stirring rod to rotate downward, thereby expanding the overall height of the stirring mechanism, enabling the stirring mechanism to fully stir the emulsion, avoiding the stirring mechanism being exposed above the liquid level, preventing the inhalation of external air or pollutants into the emulsion, reducing the possibility of bubble generation, and ensuring the demulsifying effect of the equipment.

[0014] 2. The deformation process of the stirring mechanism in the present invention can adapt to the horn-shaped structural design of the demulsifying cylinder. By optimizing the structure of the demulsifying cylinder, the flow pattern inside the demulsifying cylinder can be made relatively more gentle, and the flow of the demulsifying agent in the cylinder is more stable and effective. Combined with the deformation of the stirring mechanism, whether the liquid level of the emulsion is relatively high or low, the emulsion can be fully stirred without exposing the stirring mechanism outside the liquid level.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Most of the existing stirrers for stirring demulsifiers are fixedly provided with multiple groups of stirring blades on the stirring rod. When the amount of waste emulsion is small, the liquid level in the container is relatively low, which will cause the liquid level to be unable to cover the stirring blades. Such a stirrer rotating above the liquid level is likely to suck external air or pollutants into the emulsion, resulting in the formation of bubbles. Excessive bubbles may interfere with the action of the demulsifier on the emulsion and affect the demulsification effect.

[0024] To solve the defects existing in the above stirrer during use, please refer to Figures 1-5, a demulsification device provided by the utility model can control the height of the stirring rod according to the liquid level, so that the stirring rod can completely enter the demulsification cylinder 1, avoiding the generation of bubbles when stirring the demulsifier and optimizing the demulsification effect of the equipment. The demulsification device is based on the demulsification cylinder 1 and the cylinder cover 2 installed on the demulsification cylinder 1. Among them, the demulsification cylinder 1 is set in a horn shape, and the inner diameter of the demulsification cylinder 1 gradually increases from top to bottom. Compared with the traditional straight stirring cylinder, the flow pattern in the demulsification cylinder 1 is relatively softer, and the flow of the demulsifier in the cylinder is more stable and effective, which can reduce the possibility of turbulence caused by stirring the emulsion, thereby reducing the possibility of bubble formation; symmetrically installed on the top of the cylinder cover 2 are screw rods 9, and a pressure rod 3 is sleeved on the two screw rods 9 together. The pressure rod 3 can slide up and down outside the two screw rods 9. A driving shaft 4 is rotatably installed inside the pressure rod 3, a threaded sleeve 5 is threadedly connected to the outside of the driving shaft 4, a connecting sleeve 6 is rotatably installed at the lower end of the threaded sleeve 5, the lower end of the driving shaft 4 is fixedly connected to a chassis 8, and a plurality of stirring mechanisms 7 evenly distributed circumferentially along the center of the connecting sleeve 6 are arranged between the connecting sleeve 6 and the chassis 8. The stirring mechanism 7 is used for stirring the emulsifier to carry out the demulsification work on the emulsion.

[0025] In order to enable the stirring mechanism 7 to be applicable to emulsions with different liquid levels, refer to Figure 3 and Figure 4As shown in the figure, a main stirring rod 71 is fixedly installed outside the chassis 8. The rotation of the threaded sleeve 5 can drive the main stirring rod 71 to stir the emulsifier and emulsion. A secondary stirring rod 72 is slidably installed inside the main stirring rod 71. The secondary stirring rod 72 is used to adapt to the large inner diameter shape at the bottom of the demulsifying cylinder 1. One side of the top of the secondary stirring rod 72 is rotatably installed with a connecting rod 76. The upper end of the connecting rod 76 is rotatably installed outside the connecting sleeve 6. The up and down sliding of the connecting sleeve 6 can control the secondary stirring rod 72 to contract along the main stirring rod 71 through the connecting rod 76. A hanger 74 is installed at the bottom of the main stirring rod 71. The lower end of the hanger 74 is rotatably installed with a lower stirring rod 75. A transmission member 73 is arranged between the lower stirring rod 75 and the secondary stirring rod 72, which can drive the lower stirring rod 75 to rotate upward and unfold as the secondary stirring rod 72 extends. When the liquid level in the demulsifying cylinder 1 is relatively low, rotate the threaded sleeve 5 to drive the connecting sleeve 6 to slide downward. The connecting sleeve 6 drives the connecting rod 76 to rotate. The connecting rod 76 drives the secondary stirring rod 72 to extend from the main stirring rod 71. At the same time, the secondary stirring rod 72 drives the lower stirring rod 75 to rotate and unfold through the transmission member 73, which can shorten the overall height of the stirring mechanism 7. By driving the stirring mechanism 7 to descend through the drive shaft 4, the stirring mechanism 7 can completely enter the emulsion. And because the bottom diameter of the demulsifying cylinder 1 is relatively large, the extension of the secondary stirring rod 72 and the unfolding of the lower stirring rod 75 can expand the overall stirring diameter of the stirring mechanism 7, and can fully stir the emulsion with a relatively low liquid level. When the liquid level in the demulsifying cylinder 1 is relatively high, rotate the threaded sleeve 5 to drive the connecting sleeve 6 to slide upward. Similarly, the secondary stirring rod 72 contracts and the lower stirring rod 75 rotates downward, so that the overall height of the stirring mechanism 7 is elongated. At this time, the main stirring rod 71, the lower stirring rod 75 and the connecting rod 76 can all play a stirring role, and the stirring mechanism 7 can still fully stir the emulsion in the demulsifying cylinder 1. In summary, whether the liquid level of the emulsion in the demulsifying cylinder 1 is relatively high or low, the stirring mechanism 7 can completely immerse in the emulsion, and can ensure the stirring effect of the stirring mechanism 7 on the emulsion.

[0026] To achieve the effect that the secondary stirring rod 72 drives the lower stirring rod 75 to rotate upward and unfold when extending, a toothed plate 731 fixedly installed at the bottom of the secondary stirring rod 72, a transmission gear 732 and a passive gear 733 rotatably installed inside the hanger 74 are provided. The transmission gear 732 is arranged between the toothed plate 731 and the passive gear 733, and both the toothed plate 731 and the passive gear 733 are meshed with the transmission gear 732. A rotating rod 734 is fixedly installed inside the passive gear 733. Both ends of the rotating rod 734 pass through the hanger 74 and are fixedly connected to the lower stirring rod 75. When the secondary stirring rod 72 slides outward, it drives the transmission gear 732 to rotate through the toothed plate 731. The transmission gear 732 drives the passive gear 733 to reverse, and then drives the two lower stirring rods 75 to rotate and unfold through the rotating rod 734, which can reduce the overall stirring height of the stirring mechanism 7. Similarly, when the secondary stirring rod 72 slides inward, it can drive the lower stirring rod 75 to turn downward, which can increase the overall stirring height of the stirring mechanism 7.

[0027] Since the stirring mechanism 7 needs to rotate during the stirring operation, a servo motor 12 is fixedly installed at the top of the pressure rod 3, and a support frame for fixing the servo motor 12 is installed on the pressure rod 3. The output end of the servo motor 12 is fixedly connected to the center of the drive shaft 4. Driving the servo motor 12 can drive the drive shaft 4 to rotate, and the rotation of the drive shaft 4 can drive the entire stirring mechanism 7 to rotate to achieve stirring.

[0028] If the pressure rod 3 is only sleeved on the two lead screws 9, it will automatically fall due to its own gravity, so that the height of the stirring mechanism 7 cannot be controlled. To solve this technical problem, referring to Figure 1 as shown, a telescopic spring 10 is sleeved outside the lead screw 9. The upper and lower ends of the telescopic spring 10 are respectively fixedly installed on the cylinder cover 2 and the pressure rod 3. A limit ring 11 is threadedly connected to the outside of the lead screw 9, and the limit ring 11 is arranged above the pressure rod 3. Figure 1 The telescopic spring 10 in [[ ]] is in a deformed state. The pressure rod 3 can be lifted by the elastic force of the telescopic spring 10. The limit ring 11 is used to limit the pressure rod 3. Cooperating with the telescopic spring 10, the pressure rod 3 can be restricted at a specified height. When rotating the threaded sleeve 5 to control the state of the stirring mechanism 7, the pressure rod 3 can be pressed to drive the drive shaft 4 to descend. When the liquid level completely covers the stirring mechanism 7, then turn the limit ring 11 to the top of the pressure rod 3 to fix the pressure rod 3. Then drive the servo motor 12 to drive the stirring mechanism 7 to stir. The demulsifying cylinder 1 is set to be transparent or a viewing window is provided on the demulsifying cylinder 1, which can facilitate observing the liquid level height in the demulsifying cylinder 1 and whether the stirring mechanism 7 is completely in the emulsion.

[0029] The control mode of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention mainly aims to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
