[0041] Embodiment 1:

[0042] Please refer to Figures 1-4 , a ventilation device for the safety engineering of industrial and trading enterprises, which includes:

[0043] A ventilation duct 1, one end of the ventilation duct 1 is set as an air inlet, and the other end of the ventilation duct 1 is set as an air outlet;

[0044] A protective net plate 2, which is arranged at the position of the air inlet of the ventilation duct 1, and the protective net plate 2 is detachably connected to the ventilation duct 1;

[0045] An air guiding fan 3, which is arranged inside the ventilation duct 1 and at a position far from the air inlet, and is used for guiding air;

[0046] A filtering component 4, which is arranged inside the ventilation duct 1 and near the air inlet, and is used for filtering air;

[0047] Specifically, the filtering component 4 includes an assembly ring frame 6, a first filtering barrel 7, and a second filtering barrel 8. The outer side of the assembly ring frame 6 is threadedly connected to the inside of the ventilation duct 1. Both the first filtering barrel 7 and the second filtering barrel 8 are arranged in a conical barrel shape, and the open ends of the first filtering barrel 7 and the second filtering barrel 8 are detachably connected to the assembly ring frame 6.

[0048] Among them, in order to reduce the intrusion of sundries into the inside of the ventilation duct 1, a protective net plate 2 is fixedly connected to the end of the ventilation duct 1. In order to facilitate the replacement of the filtering component 4, the protective net plate 2 is snap-fitted with a buckle frame 5.

[0049] Furthermore, the assembly ring frame 6 includes a ring frame main body 9. One end of the ring frame main body 9 far from the ventilation duct 1 is fixedly connected with a taking and placing frame 10. Among them, in order to facilitate the removal or installation of the assembly ring frame 6, the middle of the taking and placing frame 10 is arranged in a shape of a Chinese character 'Ri'. Two limiting convex strips 11 are arranged on the inner wall of the ring frame main body 9, and the ring frame main body 9 realizes snap-fitting with the first filtering barrel 7 and the second filtering barrel 8 through the two limiting convex strips 11.

[0050] It can be seen that the first filtering barrel 7 and the second filtering barrel 8 can achieve double filtering of air. The first filtering barrel 7 can effectively filter the fluff in the air, and the second filtering barrel 8 can filter the dust and the fine fluff passing through the first filtering barrel 7; and through the detachable connection between the first filtering barrel 7, the second filtering barrel 8 and the assembly ring frame 6, the removal or installation of the first filtering barrel 7 and the second filtering barrel 8 can be realized by disassembling and assembling the assembly ring frame 6.

[0051] Embodiment 2:

[0052] The ventilation device for safety engineering of industrial and commercial enterprises provided in Example 1 is further optimized. Specifically, the assembly ring frame 6, the first filter barrel 7, and the second filter barrel 8 are made of plastic.

[0053] The above structural design can effectively improve the production efficiency of assembling the ring frame 6, the first filter barrel 7, and the second filter barrel 8, reduce production costs, and reduce replacement costs.

[0054] Example 3:

[0055] The ventilation device for safety engineering in industrial and commercial enterprises provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, the first filter barrel 7 includes a filter barrel body 12. Multiple strip-shaped ventilation grooves 13 are evenly provided on the side of the filter barrel body 12 along its length. Several hooks 14 are fixedly connected inside the filter barrel body 12 at positions on both sides of each strip-shaped ventilation groove 13. A pick-and-place plate 15 is fixedly connected inside the open end of the filter barrel body 12.

[0056] Through the above structural design, the cone-shaped design can effectively increase the filtration area, thereby avoiding the limitation of the filtration area due to the size of the pipe. The strip-shaped air vent 13 facilitates air circulation. When the air passes through the strip-shaped air vent 13, most of the lint is blocked by the hooks 14 located on both sides of the strip-shaped air vent 13 inside the filter barrel 12, thereby achieving the lint filtration effect. Furthermore, the pick-and-place plate 15 makes it easy to remove or install the first filter barrel 7 from the assembly ring frame 6.

[0057] Example 4:

[0058] The ventilation device for safety engineering in industrial and commercial enterprises provided in Example 1 has been further optimized, specifically, as follows: Figure 6 As shown, the second filter barrel 8 includes a filter barrel body 16. Multiple filter windows are evenly provided on the side of the filter barrel body 16 along its length, and a filter screen 17 is fixedly connected inside each filter window.

[0059] Through the above structural design, dust and fine hair can be effectively filtered through the filter screens 17 in multiple filter windows, thereby achieving a dual filtration effect in conjunction with the first filter barrel 7.
