Detailed Description
The utility model is further described with reference to the following figures and examples:
the first embodiment is as follows: referring to fig. 1 and 2, a filter element filtering performance detection device comprises a frame 1, a weighing mechanism 2 arranged on the frame, a shell 3 placed on the weighing mechanism, and a suction fan 4, wherein a cavity 5 is arranged inside the shell, an air outlet 6 is arranged on the left side of the shell, and the suction fan is arranged on the air outlet;
a product slot 7 is arranged in the middle of the front side of the shell, an air inlet 8 is arranged on the right side of the shell, and the product slot is arranged between the air inlet and the air outlet;
a bin 9 is arranged on the right side of the top of the shell, and a switch 10 is arranged on the bin; the bottom of the bin is communicated with the cavity, the air inlet and the air outlet are communicated with the cavity, and the bin is arranged on the right side of the product slot.
The air inlet is connected with an air inlet pipe 11, and the air exhaust end of the suction fan is detachably provided with a filter bag 12. Wherein, the air inlet end of the air inlet pipe can be connected in a clean space with a certain cleanness grade, so as to prevent the influence on the detection performance.
