[0002] The clean room environment monitoring and management system is a system for the internal environment management of the clean room. It plays a very important role. The clean room is also called a dust-free workshop, a clean room or a clean room. At the same time, the main function of the clean room is indoor pollution control. Without a clean room, pollution-sensitive parts cannot be mass-produced. At the same time, the clean room is generally equipped with a unique return air structure. The clean room refers to a well-enclosed space where air cleanliness, temperature, humidity, pressure, noise and other parameters are controlled as needed.

The utility model drives the protrusion to extend and retract through a reset spring, and the protrusion abuts in the groove, and the return air frame can be installed on the mounting frame. The installation is simple and quick. When disassembly is required, the return air frame can be removed by the opposite operation. The structure is simple and easy to disassemble and assemble. The return air frame can be quickly replaced, which is conducive to improving the effect of return air. The incoming air will first enter through the filter slot, and then pass through the coarse filter screen plate, the fine filter screen plate and the disinfection filter plate in turn, and perform multiple filtrations.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: a clean room return air structure. It includes a filter box 110, a filter mechanism 210 for filtering air is installed in the filter box 110, a cleaning component for cleaning the filter mechanism is installed on the top of the filter box 110, a moving component for driving the cleaning component to move is installed in the filter box 110, and a mounting frame 510 is installed at one end of the filter box 110;

[0028] The cleaning assembly includes a vacuum cleaner 310, which is mounted on the top of the filter box 110, a transmission pipe 320 is mounted on one end of the vacuum cleaner 310, and the end of the transmission pipe 320 away from the vacuum cleaner 310 is mounted on the top of the filter box 110, and the end of the transmission pipe 320 away from the vacuum cleaner 310 penetrates into the filter box 110, and a bellows 330 is mounted on the end of the transmission pipe 320 away from the vacuum cleaner 310, and a suction plate 340 is mounted on the end of the bellows 330 away from the transmission pipe 320, and the suction plate 340 is attached to the filter mechanism 210, and moving blocks 350 are mounted on both ends of the suction plate 340, and two groups of moving blocks 350 are mounted on the moving assembly. Impurities on the surface of the filter mechanism 210 are absorbed by the suction plate 340, and the bellows 330 and the transmission pipe 320 are transmitted to the vacuum cleaner 310. The arrangement of the bellows 330 enables the suction plate 340 to clean the filter mechanism 210 during the vertical movement.

[0029] When the filter mechanism is clogged, the vacuum cleaner 310 is started, and the vacuum cleaner 310 absorbs impurities on the filter mechanism 210 through the transmission pipe 320, the bellows 330 and the suction plate 340. At the same time, the motor 410 drives the threaded rod 430 to rotate. Under the action of the threaded rod 430 and the moving block 350, the suction plate 340 is driven to move vertically, so that the suction plate 340 can clean the entire surface of the filter mechanism 210, making it less likely for the filter mechanism 210 to be clogged, so that the filter mechanism can effectively filter the return air gas, thereby not affecting the use of the clean room.

[0030] The moving assembly includes two groups of moving grooves 420, which are respectively arranged on the inner walls of both sides of the filter box 110. A threaded rod 430 is rotatably connected in one group of the moving grooves 420, and the threaded rod 430 is threadedly connected to one group of moving blocks 350. A guide rod 440 is installed in another group of the moving grooves 420, and the guide rod 440 is slidably connected to another group of moving blocks 350. The moving assembly also includes a motor 410, which is installed on the top of the filter box 110. The output end of the motor 410 penetrates into one group of the moving grooves 420, and the output end of the motor 410 is transmission-connected to one end of the threaded rod 430. The threaded rod 430 drives one group of moving blocks 350 to move vertically, so that the suction plate 340 moves vertically, so that the suction plate 340 can clean the entire filtering mechanism 210, thereby avoiding excessive impurities in the filtering mechanism 210 and affecting the use of the filtering mechanism 210. The movement of the suction plate 340 is kept stable through the guide rod 440.

[0031] One end of the installation frame 510 is installed with a return air frame 520, and the return air frame 520 is provided with multiple groups of return air slots 530, and the multiple groups of return air slots 530 are arranged at equal distances. The other end of the installation frame 510 is installed with four groups of limit blocks 540, and the four groups of limit blocks 540 are provided with limit holes 550.

[0032] One end of the filter box 110 is provided with four groups of limit grooves 120 used in conjunction with the limit blocks 540, and one end of the filter box 110 is provided with four groups of adjustment grooves 130. The four groups of adjustment grooves 130 are all slidably connected with the moving plates 140, and one side of the four groups of moving plates 140 is installed with positioning rods 150 used in conjunction with the limit holes 550, and the ends of the four groups of positioning rods 150 away from the moving plates 140 are respectively penetrated into the four groups of limit grooves 120.

The four groups of connecting rods 160 are all sleeved with springs 170 , one end of the four groups of springs 170 are respectively mounted on the four groups of moving plates 140 , and the other ends of the four groups of springs 170 are respectively mounted on the inner walls of the four groups of adjusting slots 130 .

[0033] When the return air frame 520 needs to be replaced, the handle 180 is pulled so that the handle 180 drives the connecting rod 160 to move, and the connecting rod 160 drives the movable plate 140 to move, and the movable plate 140 drives the positioning rod 150 to move, so that the positioning rod 150 and the limiting hole 550 are separated, thereby releasing the limit on the limiting block 540, separating the limiting block 540 and the limiting groove 120, disassembling the installation frame 510, and replacing the return air frame 520.
