Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to a supply and return air system for a large clean room. Background Art

[0002] Indoor air conditioning purification mainly involves using the air conditioning system to improve indoor air quality, which includes removing pollutants from the air, adjusting temperature and humidity, and introducing fresh air.

[0003] In related technologies, clean rooms generally use the form of nozzle-side air supply and louver-side air return. However, the above method only has a good purification effect on houses with a height of about 4.5m. If the height exceeds 8m, the purification effect is not very ideal. It can only ensure the cleanliness requirements below the height of the nozzle. The area above the house body may not be able to reach it, which may affect the purification efficiency in the clean room. Utility Model Content

[0011] By adopting the above technical solution, the air flowing through the vent can be purified by the filter plate. At the same time, when the return fan blades are removed through the fixing assembly, the filter plate can be cleaned, thereby further improving the air purity in the clean room.

[0012] Optionally, a mounting frame is fixedly connected to the vent, the return air louver is placed in the mounting frame, a slide groove is provided on the return air louver, the fixing assembly includes a plug rod slidably connected to the slide groove, a shift block is fixed to the plug rod, the shift block is placed outside the slide groove, a plug groove for the plug rod is provided on the mounting frame, and an elastic member is provided in the return air louver for keeping the plug rod plugged in the plug groove.

[0013] By adopting the above technical solution, the plug-in rod can be disengaged from the plug-in slot by toggling the toggle block, thereby canceling the fixation of the return air louver on the installation frame.

[0014] Optionally, the elastic member is configured as a spring, and the spring is fixed between the plug-in rod and the bottom of the slide groove. Under the contact of the spring, the plug-in rod is pressed tightly against the plug-in groove.

[0015] By adopting the above technical solution, under the action of the spring, the plug rod can be kept in a state of being tightly pressed against the plug slot.

[0016] Optionally, a cleaning groove is provided at the bottom of the vent, and a dust collecting hopper is placed in the cleaning groove.

[0017] By adopting the above technical solution, the dust settled in the cleaning tank can be collected centrally through the dust collecting hopper in the cleaning tank, and the dust collecting hopper can be cleaned regularly by dumping the dust in the dust collecting hopper, so as to maintain a better environment in the cleaning room.

[0018] Optionally, a protective mesh cover is provided on the upper portion of the fan filter unit, and a positioning component for fixing the protective mesh cover on the upper portion of the housing body is provided on the protective mesh cover.

The return air louvers 1 are placed within the mounting frames 22. The return air louvers 1 are provided with two chute slots 11, one on each side of the return air louver 1 and communicating with the end faces of the return air louver 1.

[0036] Reference Figure 3 、 Figure 4 and Figure 5 The fixing assembly 3 includes a plug-in rod 31 that is slidably connected to the chute 11. A shift block 32 is fixed to the plug-in rod 31 and is located outside the chute 11. The mounting frame 22 is provided with a plug-in slot 221 for receiving the plug-in rod 31. The plug-in slots 221 correspond one to one with the plug-in rod 31. The return air louver 1 is provided with an elastic member 33 for keeping the plug-in rod 31 inserted in the plug-in slot 221.

[0037] In this embodiment, the elastic member 33 is configured as a spring, which is fixedly connected between the plug rod 31 and the bottom of the slide groove 11 . Under the contact of the spring, the plug rod 31 remains tightly pressed in the plug groove 221 .

[0038] By shifting the shift block 32 , the spring can be compressed and the plug-in rod 31 can be disengaged from the plug-in slot 221 , thereby canceling the fixation of the return air louver 1 on the mounting frame 22 .

[0039] A filter assembly 4 for filtering air is provided in the vent 21 . The filter assembly 4 includes two filter plates 41 . The two filter plates 41 are respectively fixedly connected to the two return air louvers 1 , and the two filter plates 41 are placed between the two return air louvers 1 .

[0040] The air flowing through the return air louver 1 can be purified by the filter plate 41 to purify the air flowing through the ventilation opening 21 .

[0041] A cleaning groove 23 is provided at the bottom of the vent 21 . The cleaning groove 23 is arranged along the width direction of the house body 2 . A dust collecting hopper 6 is placed in the cleaning groove 23 . The dust collecting hopper 6 is arranged along the opening direction of the cleaning groove 23 .

[0042] Most of the dust blocked by the filter plate 41 can fall into the dust collecting hopper 6 , and the dust settled in the cleaning tank 23 can be collected centrally by the dust collecting hopper 6 in the cleaning tank 23 .

[0043] Reference Figure 1 and Figure 6 A plurality of fan filter units 5 are mounted on the upper end of the housing body 2 and communicate with the interior of the housing body 2. A protective mesh cover 7 is provided above the fan filter units 5. The protective mesh cover 7 is configured in a rectangular parallelepiped shape and is placed within the fan filter units 5. The protective mesh cover 7 is provided with a positioning assembly 8 for securing the protective mesh cover 7 to the upper portion of the housing body 2.

[0044] The positioning assembly 8 includes a locking bolt 81 threadedly connected to the bottom of the protective mesh cover 7. There are four locking bolts 81 and they are respectively located at the four corners of the protective mesh cover 7. The rod of the locking bolt 81 passes through the protective mesh cover 7 and is threadedly connected to the top of the house body 2.

[0045] Therefore, the locking bolt 81 can be rotated to separate the rod of the locking bolt 81 from the building body 2 , thereby achieving the removal of the protective net cover 7 from the upper part of the building body 2 .

[0046] The implementation principle of the embodiment of the present application is: the interior of the house body 2 can be ventilated and cleaned from top to bottom through multiple fan filter units 5, and then the air flow is discharged outside the house body 2 through the return air louver 1 at the bottom, thereby completing the air purification cycle inside the house body 2.
