Description

Vacuum pressure impregnation equipment and its vacuum liquid storage tank

technical field

The utility model relates to a liquid cooling device, in particular to a vacuum liquid storage tank and vacuum pressure impregnation equipment with the vacuum liquid storage tank.

Background technique

In the vacuum pressure impregnation equipment, the vacuum liquid storage tank is mainly used for the storage of the impregnation liquid. When the liquid needs to be transported to the impregnation tank for impregnation, it is generally required to heat the liquid to 35°C to 40°C to reduce its viscosity so that the liquid can better penetrate into the gap between the workpiece; after impregnation, return to the vacuum liquid storage tank for storage , all require cooling down to below 20°C to ensure its life. In order to achieve this purpose, the general vacuum liquid storage tank is equipped with inner and outer coils, and the outer coil exchanges heat with the liquid through the wall of the vacuum liquid storage tank. The outer surface of the inner coil is directly in contact with the liquid for heat exchange, and a stirring device is provided for rapid heat exchange. During the heating process of the liquid, due to the large temperature difference between the heating medium and the liquid, it can generally meet the requirements; during cooling, due to the small temperature difference between the two heat exchange media, the cooling is relatively slow, especially when the impregnated liquid medium is more expensive. Users purchase less, and often only fill half of the vacuum liquid storage tank. The heat exchange tube on the upper part of the vacuum liquid storage tank does not contact the medium at all, so the heat transfer is slower.

Referring to Fig. 1 to Fig. 3, the embodiment of the utility model discloses a vacuum liquid storage tank, which includes a tank body 1, which is used for vacuum storage of liquid for dipping, wherein the liquid is generally insulating varnish . Inside the tank body 1 is provided with an inner heat exchange tube 2 . The inner heat exchange tube 2 can exchange heat with the liquid stored in the tank body 1 . An external heat exchange tube 9 may also be provided on the outer wall of the tank body 1 , and a stirring device for stirring the liquid in the tank body 1 may also be provided on the tank body 1 . An infusion tube 3 is provided at the bottom of the tank body 1 , and the infusion tube 3 is used for outputting liquid outward, and a liquid return tube 4 extending into the tank body 1 is provided at the top of the tank body 1 . The liquid can flow back into the tank body 1 through the liquid return pipe 4 .

A liquid distribution pipe 5 is connected to the lower part of the liquid return pipe 4, and the liquid distribution pipe 5 is located above the inner heat exchange tube 2, and a plurality of pipes for supplying liquid to the inner heat exchange pipe 2 are arranged on the liquid distribution pipe 5. Drip hole6. When the liquid flows back to the tank body 1 from the liquid return pipe 4, it will first flow to the liquid distribution pipe 5, and then fall to the inner heat exchange tube 2 from the drip hole 6 on the liquid distribution pipe 5, thus, the inner heat exchange tube 2 can be used. The heat exchange tube 2 dissipates heat from the liquid. The drip holes 6 are evenly distributed on the liquid distribution pipe 5 so that the liquid can evenly drop on the inner heat exchange tube 2 .

In this embodiment, the inner heat exchange tube 2, the outer heat exchange tube 9 and the liquid distribution pipe 5 are all annular pipes, the liquid distribution pipe and the inner heat exchange tube are arranged concentrically, and the liquid distribution pipe 5 and the inner heat exchange tube 2 The central diameters of the tubes are consistent, and when the liquid falls from the drip hole 6, it can just land on the inner heat exchange tube 2. The inner heat exchange tube 2 and the outer heat exchange tube 9 may specifically be spiral tubes and also be composed of a plurality of concentric circular tubes. The liquid pipe 5 can be a complete ring, or a semi-ring with an opening. As shown in Figure 3, in this embodiment, the liquid pipe 5 is semi-circular. In this way, the liquid pipe 5 can avoid parts such as the rotating shaft of the stirring device during installation, thereby facilitating the installation of the liquid pipe 5. disassembly.

It can be seen from FIG. 1 to FIG. 3 that a plurality of liquid conduits 8 for delivering liquid to the inner wall of the tank body 1 are also provided on the liquid distribution pipe 5 . The upper ends of these catheter tubes 8 are connected to the liquid pipes 5 , and the lower ends are inclined outwards and close to the inner wall of the tank body 1 . When the liquid flows in the liquid distribution pipe 5 , a part of the liquid will flow from the liquid conduit 8 to the inner wall of the tank body 1 , so that the inner wall and the outer heat exchange tube 9 can be used to exchange heat for this part of the liquid.

In the vacuum liquid storage tank of the present utility model, when recovering the liquid used for immersion operation, the liquid flows into the inside of the tank body 1 from the top of the tank body 1 through the liquid return pipe 4, and then the liquid drips from the liquid distribution pipe 5 Hole 6 and catheter 8 outflow. Part of the liquid flows to the inner heat exchange tube 2, then flows down from the inner heat exchange tube 2 and is cooled by the inner heat exchange tube 2, and the other part of the liquid flows to the inner wall of the tank body 1, and is exchanged heat by the inner wall and the outer surface of the tank body 1 Tube 9 is cooled. The vacuum liquid storage tank of the present utility model can also make full use of the internal heat exchange tube for heat dissipation when there is less liquid in the tank body 1 and the liquid level is low, which avoids the partial internal exchange caused by the low liquid level in the prior art. The defect that the heat pipe does not participate in the cooling work significantly improves the cooling speed of the liquid and prolongs the life of the liquid.
