Drawings

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the figure:

fig. 1 is a schematic structural view of a defoaming stirring device according to an embodiment of the present invention.

In the drawings, like parts are provided with like reference numerals. The figures are not drawn to scale.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a defoaming stirring device according to an embodiment of the present invention. As shown in fig. 1, the defoaming stirring apparatus 100 includes a tank 1. The tank 1 comprises an inlet 1a arranged on its top and capable of introducing the potting adhesive, and an outlet 1b arranged on its bottom and capable of discharging the potting adhesive. The defoaming stirring device 100 further includes a rotating shaft 2, a helical blade 3, and a driving member 4. The rotating shaft 2 is rotatably inserted into the storage tank 1 from the top of the storage tank 1, the helical blade 3 is wound on the rotating shaft 2 and is positioned in the storage tank 1, and the driving part 4 is arranged on the storage tank 1 and is connected with the rotating shaft 2. The driving part 4 can drive the rotating shaft 2 and the helical blade 3 to synchronously rotate, and the rotating shaft 2 and the helical blade 3 can stir and remove bubbles of pouring sealant in the storage tank 1. The potting compound can be selected from an AB glue, preferably a mixture of epoxy resin and epoxy resin hardener with bubbles, or a mixture of polyurethane and polyurethane hardener with bubbles.

The utility model discloses remove bubble formula agitating unit 100 can drive pivot 2 and helical blade 3 through driver part 4 and be synchronous revolution in basin 1 to force the pouring sealant to rise earlier and descend in basin 1 again, can stir and remove the bubble to the pouring sealant in basin 1 under driver part 4's drive with helical blade 3 in order to guarantee pivot 2. That is to say, this bubble removal formula agitating unit 100 can stir the casting glue and can remove the bubble to the casting glue again, can improve the implementation efficiency of embedment technology when guaranteeing embedment quality. In fact, the pouring sealant rises first under the conveying action of the spiral blade 3, and then falls like a waterfall after separating from the edge of the spiral blade 3, so that the contact area of the pouring sealant and air is increased, air bubbles in the pouring sealant are promoted to be quickly mixed into the air, and the purpose of removing the bubbles is achieved. The utility model discloses remove bubble formula agitating unit 100's simple structure, assembly are easy, use safe and reliable, and the implementation of being convenient for is popularized and applied.

The central axis of the rotating shaft 2 and the central axis of the storage tank 1 can be coincided or not coincided, but in order to ensure that the defoaming stirring device 100 can stir more uniformly and remove bubbles better, the central axis of the rotating shaft 2 and the central axis of the storage tank 1 are coincided best. Since the rotation axis 2 is arranged in the center of the top of the tank 1, the inlet 1a should be offset from the center of the top of the tank 1, i.e. the radial distance of the inlet 1a to the side wall of the tank 1 is larger than the radial distance of the inlet 1a to the centre axis of the tank 1. Although the inlet 1a needs to be offset from the top center of the storage tank 1 in order to avoid the rotating shaft 2, the outlet 1b can be arranged at the bottom center of the storage tank 1 to more completely discharge the potting adhesive in the storage tank 1 because the rotating shaft 2 does not extend into the bottom of the storage tank 1.

Researches show that the proportional relation between the inner diameter and the outer diameter of the helical blade 3 and the inner diameter of the storage tank 1 influences the stirring effect and the defoaming effect of the defoaming stirring device 100 on the pouring sealant. Through a large number of experiments, it is known that when the outer diameter of the helical blade 3 is selected to be 0.75-0.95 times of the inner diameter of the storage tank 1, and the inner diameter of the helical blade 3 is 0.05-0.15 times of the inner diameter of the storage tank 1, the bubble removing type stirring device 100 performs uniform stirring and clean bubble removal on the pouring sealant. However, in order to further improve the stirring effect and the defoaming effect of the defoaming stirring device 100, the pitch of the spiral blade 3 is preferably 0.1 to 0.2 times the height of the storage tank 1.

In order to save the cost of the bubble removing type stirring apparatus 100, the storage tank 1, the rotation shaft 2 and the spiral blade 3 may be made of metal or resin. In order to save the cost of the bubble removing type agitation apparatus 100 again, the driving part 4 includes an electric motor, an engine or a hydraulic motor capable of outputting power to provide the driving force of the rotation shaft 2 and the helical blade 3 by using the electric motor, the engine or the hydraulic motor which is easy to purchase without special design and has a low cost. When the driving part 4 is selected as a motor and the output rotating speed thereof is too fast, the driving part 4 may further include a reduction gearbox provided between the motor and the rotating shaft 2 and used for transmitting power. In order to accurately control the rotation speed and the rotation angle of the motor, the motor can be selected as a servo motor.

In order to prevent the potting compound from flowing out of the outlet 1b after potting without defoaming, a valve can be mounted on the outlet 1 b. To facilitate the installation of the shaft 2 and the spiral blade 3, the tank 1 is preferably composed of an inverted cylinder and a bottom cover. The tank 1 may have a see-through area (e.g., glass area) to facilitate the user's observation of the defoaming and stirring effect of the helical blade 3.

To sum up, this remove bubble formula agitating unit 100 can remove the bubble to the casting glue in the stirring process, can improve the implementation efficiency of embedment technology when guaranteeing the embedment quality from this.
