Description

Technical Field

[0001] The utility model relates to the technical field of air purification, and in particular to a high-efficiency filtering mechanism for a mobile purification room. Background Art

[0002] The concept of mobility means that the clean room can be moved to other locations in the clean plant or even relocated as a whole to a new plant area without rebuilding the clean room itself, or a single module that needs to be modified can be moved out of the production area without affecting the production of other modules. When this type of modular clean plant is put into production, the air inside it needs to be purified so that the air quality inside it meets the use standards to improve the production quality in subsequent production, and this requires the use of a high-efficiency filtration mechanism in a mobile purification room.

[0003] Patent document CN216080170U discloses a high-efficiency filtering mechanism for a mobile purification room, "including a main body, a first air suction cavity formed at the left front end of the main body, a second air suction cavity formed at the left rear end of the main body, a third air suction cavity formed on the left side of the first air suction cavity, a filter cavity formed on the right side of the main body, a filter box horizontally embedded in the filter cavity, a cavity provided in the filter box, a first filter screen formed on the left side wall of the filter box, a second filter screen formed on the right side wall of the filter box, the first filter screen and the second filter screen both pass through the cavity, a diverter device is provided on the right side of the filter box, the left side of the diverter device is connected to the filter box, the right side of the diverter device is connected to the right side of the filter cavity, and the diverter device is formed into a "ridge" shape."

[0004] The above-mentioned equipment sterilizes through multiple layers of filtration in the filter box, and finally discharges the air from the first air outlet and the second air outlet, thereby effectively sterilizing and purifying the air. However, after the equipment purifies the air, the discharge location is relatively single, and after the purified air is discharged separately in one direction, it is inevitable that the relatively pure air in the room will be unevenly distributed, thereby causing physical effects on the staff using it, and this requires the staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that a high-efficiency filtering mechanism in a mobile purification room in the prior art easily causes uneven distribution of relatively pure air in the room after purification, thereby providing a high-efficiency filtering mechanism in a mobile purification room.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A working box, wherein a first exhaust fan is fixedly connected to the top of the working box, a ventilation duct is fixedly connected to the inner wall of the working box, and the bottom of the first exhaust fan is fixedly connected to the top of the ventilation duct, a mounting frame is arranged around the inner wall of the ventilation duct, a filter is arranged on the inner wall of the mounting frame, a second exhaust fan is arranged around the surface of the working box, and one side of the second exhaust fan is fixedly connected to one end of the ventilation duct.

[0009] As an optional technical solution, a purification box is fixedly connected to the inner bottom wall of the ventilation pipe, an activated carbon plate is provided on the inner wall of the purification box, and a ventilation groove is opened at the bottom of the purification box.

[0010] As an optional technical solution, movable plates are rotatably connected to both sides of the working box, and a handle is fixedly connected to one side of the movable plate.

[0011] As an optional technical solution, first support columns are fixedly connected to the four sides of the bottom of the working box, and second support columns are slidably connected to the surfaces of the first support columns.

[0012] As an optional technical solution, a thread groove is provided on one side of the first support column, and a hand wheel is threadedly connected to one side of the second support column.

[0013] As an optional technical solution, a reinforcement rod is fixedly connected to one side of the second support column, and a universal wheel is fixedly connected to the bottom of the second support column.

[0014] As an optional technical solution, a baffle is fixedly connected to the surface of the ventilation duct, and a guide fan is fixedly connected to the inner top wall of the ventilation duct.

[0015] The utility model technical solution has the following advantages:

[0016] 1. The utility model sends the air at the top of the equipment into the ventilation duct for filtration through the first exhaust fan. The filtered air can be evenly transported to the surroundings of the equipment through the second exhaust fan, thereby improving the overall air quality in the room. Discharging air to the surroundings can avoid the situation where the purified air is concentrated in a single location in the room and affects the people in the room, thereby improving the safety and purification effect of the equipment.

[0017] 2. The utility model can filter the air passing through the ventilation duct by setting a purification box at the bottom of the ventilation duct. The three groups of activated carbon plates set in the purification box can absorb most of the harmful gases in the air, thereby improving the purification effect of the equipment.

The activated carbon plate 8 in the purification box 7 can adsorb most of the harmful substances in the air, thereby purifying the air. The air is purified by three groups of activated carbon plates 8 and finally discharged through the ventilation slots 9 at the bottom of the purification box 7.

The activated carbon plate 8 in the purification box 7 adsorbs most of the harmful substances in the air, thereby purifying the air, and finally discharges it through the ventilation slot 9 at the bottom of the purification box 7. The air after the second filtration is affected by the second exhaust fan 6, thereby dividing the air into roughly four parts, and transporting the air to the filter 5 at the bottom of the ventilation duct 3. After the third filtration, the filtered air is finally discharged through the second exhaust fan 6.
