DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a vacuum pump 9 for wind blade processing, including: a box body 4, an air inlet pipe and an air outlet pipe 8 are arranged on the box body 4, the air inlet pipe includes a first air inlet pipe 1 and a second air inlet pipe 3, the first air inlet pipe 1 and the second air inlet pipe 3 are connected through a mixed flow box 2, the second air inlet pipe 3 is connected to the box body 4, the air outlet pipe 8 is connected to the vacuum pump 9, a partition 5 is arranged in the box body 4, a through hole is arranged on the partition 5, and a filter screen 6 is arranged on the through hole. The box body 4 is a metal box body, the vacuum pump 9 is connected to the box body 4 through a conduit, the vacuum pump 9 can choose a vacuum pump currently available on the market, the partition 5 is a metal plate, the filter screen 6 is pasted on the metal plate, the filter screen 6 can use a filter screen specially used for filtering resin, or a filter screen made of sponge material, the air inlet pipe and the air outlet pipe 8 are both metal pipes, and the mixed flow box 2 is a rectangular metal box.

[0022] A baffle 7 is hinged on the partition 5, and the baffle 7 covers the through hole. The baffle 7 is a metal plate, and is hinged above the through hole. When in use, the baffle 7 naturally droops and covers the through hole. When the airflow velocity is fast, the airflow pushes the baffle 7, so that the baffle 7 is lifted, and the speed of the airflow is increased. The size of the baffle 7 is larger than the size of the through hole, and the hinge axis on the baffle 7 is set horizontally.

[0023] A first adsorption pad 14 is provided at the bottom of the box body 4. A plurality of first connecting rods 10 are provided in the box body 4, and a second adsorption pad 11 is provided on the first connecting rods 10. A plurality of second connecting rods 13 are provided in the box body 4, and a third adsorption pad 12 is provided on the second connecting rods 13. The first adsorption pad 14 is pasted on the bottom of the box body 4.

[0024] The first adsorption pad 14, the second adsorption pad 11 and the third adsorption pad 12 can be special adsorption pads for adsorbing resin, or sponges, etc. Due to the obstruction in the device, the airflow will be changed in direction many times. When the airflow changes direction, the mass of the small resin droplets is greater than that of air, and the inertia is greater than that of air. When the airflow changes direction, it is difficult for the small resin droplets to change direction, so they will collide with the adsorption plate and be absorbed by the adsorption plate.

[0025] When in use, the small resin droplets mixed in the air in the pipeline will be blocked by the partition 5 and the three adsorption pads, which can greatly reduce the possibility of the resin entering the vacuum pump 9 and effectively improve the service life of the vacuum pump 9; at the same time, when the air flow is large, the larger airflow will push up the baffle 7 through the filter 6, so that the air flow resistance in the box 4 is greatly reduced. At this time, the filter 6 will filter a part of the small resin droplets, and the use effect is good.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
