[0028] The first-stage purification rack 2 is W-shaped, and the first-stage purification rack 2 and the second-stage purification rack 3 are fixedly connected to the purification cabin 1. The top and bottom inner walls of the purification cabin 1 are provided with connecting blocks 1b. The first-stage purification rack 2, the second-stage purification rack and the 3 connecting blocks 1b are fixedly connected by welding, and the purification rack 2 and the second-stage purification rack 3 have the same structure and are both W-shaped. The front-stage filter screen 6 is fixed by the limiting of the slot 2a, and the front-stage filter screen 6 is placed obliquely. After the exhaust gas is introduced, the contact area between the exhaust gas and the front-stage filter screen 6 is increased to improve the filtering and purification efficiency.

[0029] See also Figure 2 The front-stage filter 6 includes a mesh frame 6a and a filter body 6b. The filter body 6b is an activated carbon filter cotton. One end of the mesh frame 6a is provided with an anti-slip pattern 6c. The front-stage filter 6 can be easily disassembled, replaced and cleaned. When replacement is required, the purification cabin 1 can be opened by opening the sealing door 9. At this time, the front-stage filter 6 is taken out through the anti-slip pattern 6c and pulled out for replacement. The first-level purification frame 2 and the second-level purification frame 3 are fixedly connected to the purification cabin 1 to provide support.

[0030] There are two tertiary purification holes 4a, which are respectively arranged at the upper and lower ends of the baffle 4. After the exhaust gas has undergone two rounds of purification, it enters the tertiary purification chamber 1a from the upper and lower tertiary purification holes 4a, and is discharged from the exhaust port after passing through the rear filter 5a under the guidance of the fan 8.

[0031] The rear purification rack 5 is placed horizontally, and a rear filter screen 5 a is arranged on the rear purification rack 5 . The aperture of the rear filter screen 5 a is smaller than that of the front filter screen 6 , and granular activated carbon is arranged on the rear filter screen 5 a .

The horizontal position of the exhaust port is in the middle, that is, between the two three-stage purification holes 4a. When the exhaust gas after two rounds of purification enters the three-stage purification chamber 1a from the three-stage purification hole 4a, it is guided by the fan 8 and concentrated in the direction of the exhaust port. In the process, it passes through the rear-stage filter 5a for three-stage filtration.

[0034] A sealing door 9 is provided on one side of the purification cabin 1 .

[0035] The specific working principle is as follows: when the printing machine is in use, the air intake hood 7 is placed above the printing machine. The ink generated during printing and the exhaust gas generated by the machine itself are collected through the air intake hood 7, and the fan 8 provides negative pressure for the exhaust gas collection and sends it into the purification cabin 1. After entering, the exhaust gas first passes through the first-level purification rack 2 and the second-level purification rack 3. During the process, it is double-filtered by the front-stage filter net and then enters the third-level purification chamber 1a through the third-level purification hole 4a on the baffle 4. Finally, it is filtered and purified by the rear-stage filter net 5a and then guided by the fan 8 to be discharged outdoors.
