Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 4, the vacuum pumping device 100 includes a box body 110, the box body 110 has an inner cavity 111 and a door 120 for opening or closing the inner cavity 111, a vacuum pump 130 and a water tank 170 (refer to fig. 2) adjacent to the vacuum pump 130 are installed inside the box body 110, the water tank 170 is used for containing a working fluid, such as circulating water, an air outlet 112 is opened on the box body 110, an induced draft fan 140 is installed at the air outlet 112, an air inlet 113 is opened on a first side wall 110a of the box body 110, an installation opening 114 communicating with the air inlet 113 is opened on a second side wall 110b of the box body 110 adjacent to the first side wall 110a, and the filter screen 150 is inserted into the air inlet 113 from the installation opening 114.
