[0030] Please refer to Figures 1-7 The purpose of the present embodiment is to provide a rapid defoaming device, which comprises a bottom plate 1, wherein the bottom plate 1 is provided with a defoaming device, and the defoaming device at least comprises a shell 2, wherein the shell 2 is fixedly provided with supporting legs at the bottom four corner edges, the supporting legs are arranged on the upper surface of the bottom plate 1, and the supporting legs are conical, the diameter gradually decreases from bottom to top, the contact area with the bottom plate 1 is increased, the stability is high, and stable supporting force can be provided.

[0031] A stirring cavity 21 for placing red glue is formed in the shell 2, a stirring part 3 for stirring the red glue is rotatably arranged at the top of the shell 2, the stirring part 3 at least comprises a spiral stirring rod 33 and a plurality of stirring rods 34, a spoiler 341 is fixedly arranged on the side wall of the stirring rod 34, and the inclination angles of the spoilers 341 are irregularly arranged and different from each other.

[0032] The stirring part 3 further comprises a fixed plate 31, the fixed plate 31 is fixedly provided with a connecting ring 32 near the bottom of the four peripheral edges, and two annular protrusions are fixedly arranged on the outer wall of the connecting ring 32.

[0033] The top of the shell 2 is provided with a groove 23, two annular grooves are formed in the inner wall of the groove 23, the connecting ring 32 is inserted into the groove 23, and the annular protrusion is matched and clamped with the annular groove. When the connecting ring 32 is inserted into the groove 23, the annular protrusion on the connecting ring 32 will naturally be clamped with the annular groove in the inner wall of the groove. This clamping method is not only stable and reliable, but also can effectively prevent the stirring part 3 from shaking or falling off during the working process, thereby ensuring the stable operation of the whole equipment.

[0034] The fixed plate 31 is a T-shaped cylinder, the upper part of the fixed plate 31 has a larger diameter than the lower part, and the top of the fixed plate 31 is fixedly provided with a power source 6, which is preferably a micro motor. The output shaft of the micro motor is fixedly connected with the center of the top of the fixed plate 31. The fixed plate 31 is driven to rotate by the power source 6, and the micro motor is fixedly installed on the external motor frame.

[0035] The top of the stirring cavity 21 is provided with a feeding cavity, the lower part of the fixed plate 31 is inserted into the stirring cavity 21, and the spiral stirring rod 33 is fixedly arranged at the center of the bottom of the fixed plate 31. The spiral blades of the spiral stirring rod 33 not only increase the contact area with the red glue, but also effectively disperse, mix and defoam the red glue through the centrifugal force generated by rotation.

[0036] During the stirring process, the spiral stirring rod 33 rotates around the axis of the fixed plate 31 at a certain speed under the drive of the power source 6. With the rotation of the spiral stirring rod 33, the red glue is continuously rolled up, thrown down and mixed, so as to realize the sufficient contact and reaction between the red glue. At the same time, the rotation of the spiral stirring rod 33 also generates strong shearing force and impact force, which helps to quickly discharge the bubbles in the red glue, so as to achieve the purpose of defoaming.

[0037] The width of the spoiler 341 gradually increases from top to bottom, and the bottom of the spoiler 341 has a larger width, which can better contact with the bottom red glue, increase the contact area of stirring, and as shown in Figure 5 The vertical section side wall of the spoiler 341 is designed to be inclined upward and gradually reduced, which helps to form a bubble channel from bottom to top, and is more conducive to guiding the bubbles in the bottom red glue upward, thereby improving the stirring efficiency and defoaming efficiency.

[0038] A plurality of limiting grooves 311 are fixedly formed in the bottom of the fixed plate 31, and the stirring rods 34 are arranged in a circular array with the center of the fixed plate 31 as the center. Since the stirring rods 34 are arranged in a circular array with the center of the fixed plate 31 as the center, a more uniform and strong stirring force field can be formed when the stirring part rotates, thereby improving the stirring effect and defoaming efficiency,

[0039] Since one end of the stirring rod 34 is threadedly installed in the limiting groove 311, the angle of the stirring rod 34 can be adjusted at will, thereby realizing the rotational adjustment of the angle of the spoiler 341. By adjusting the angle of the spoiler 341, the turbulence of the stirring cavity 21 can be adjusted, so that the stirring rod 34 can generate fluid power in different directions during rotation, thereby realizing the control of the defoaming efficiency.

[0040] A screw groove 312 is formed in the top of the limiting groove 311, and a fixed rod 342 is fixedly connected to the top of the stirring rod 34. The fixed rod 342 is threadedly installed in the screw groove 312. The limiting groove 311 at the bottom of the fixed plate 31 not only provides accurate positioning for the stirring rod 34, but also provides key support for the stable installation of the stirring rod 34 through the screw groove 312 formed in the top thereof.

[0041] One end of the fixed rod 342 is threadedly provided with a nut 35, and the nut 35 is located on the upper surface of the fixed plate 31. The nut 35 is used to fixedly install the stirring rod 34 on the fixed plate 31. When the stirring rod 34 is screwed into the screw groove 312 and reaches a predetermined position, the nut 35 can be tightened on the fixed rod 342, so that the lower surface of the nut 35 is tightly attached to the fixed plate 31. The lower surface of the nut 35 and the fixed plate 31 are also provided with a gasket. The main function of the gasket is to increase the contact area, disperse the pressure, prevent the fastener from loosening, and thus ensure that the stirring rod 34 will not loosen or fall off due to vibration or external force.

[0042] This installation method not only facilitates the installation and disassembly work of the operator, but also makes the structure of the entire stirring part 3 more compact and neat. At the same time, the tightening degree of the nut 35 can also be adjusted according to the actual situation to ensure the stability and reliability of the stirring rod 34 during the stirring process.

[0043] A vibration motor 5 is fixedly arranged at the center of the bottom of the shell 2. The vibration motor 5 is usually more suitable for high-viscosity red glue at a lower frequency (for example, 20Hz-50Hz), because low-frequency vibration can provide longer waveforms, which helps the rising of larger bubbles. A smaller amplitude (such as 1mm-3mm) is required because a larger amplitude may help larger bubbles rise in some cases. In order to be more suitable for fine operation, a small amplitude is selected to avoid introducing new bubbles and reducing unnecessary disturbance. The appropriate vibration time is determined according to the capacity and needs of the red glue, which is usually from a few minutes to half an hour.

[0044] A vacuum pump 4 for air extraction is fixedly arranged on one side wall of the shell 2. When the red glue to be defoamed is injected into the defoaming cylinder of the device to form a closed environment, the vacuum pump 4 extracts air from the stirring cavity 21 through the vacuum pump, so as to form a negative pressure environment in the stirring cavity 21, thereby forcing the bubbles in the red glue to escape.

[0045] The utility model discloses a stirring cavity 21 is set up in the shell 2, and the stirring cavity 21 is provided with the stirring part 3, the stirring part 3 is provided with the spiral stirring rod 33 and the stirring rod 34, the shell 2 bottom center installs the vibration motor 5, and the shell 2 one side lateral wall installs the vacuum pump 4, injects red gum to the stirring cavity 21, and the stirring rod 34 one end is screwed in the limiting groove 311, and the screwing installation depth of each stirring rod 34 is different, in this process, the fixed rod 342 is screwed in the screw groove 312, and the fixed rod 342 one end stretches out fixed plate 31 top, when the stirring rod 34 position adjustment is finished, the fixed rod 342 stretchout end screwing sets the nut 35, makes the nut 35 lower surface and fixed plate 31 upper surface fit to fix the position of fixed rod 342 through the screwing of nut 35, thereby the position of stirring rod 34 is fixed, then the connecting ring 32 is inserted and is set in the recess 23, with the in-depth of annular protruding and the clamping of ring groove to realize the fixation of stirring part 3 on the shell 2, then the air in the stirring cavity 21 is extracted and is simply defoamed through the vacuum pump 4, the fixed plate 31 is rotated through the power source 6 drive, thereby spiral stirring rod 33 and stirring rod 34 are rotated to stir red gum, and then drive vibration motor 5 uses low frequency vibration to export the bubble in red gum upwards, gradually completes the defoaming work of red gum.
