Description

Technical Field

[0001] The utility model relates to the technical field of 100-class laminar flow hoods, in particular to an ultra-clean 100-class laminar flow hood. Background Art

[0002] The Class 100 laminar flow hood is a device that can provide highly clean air, meet Class 100 purification standards, and effectively filter dust particles and microorganisms in the air.

[0003] Its working principle is to filter the air through a high-efficiency filter to form a vertical unidirectional flow, thereby achieving the purpose of purifying the air.

[0004] In the prior art, such Class 100 laminar flow hoods are generally installed at a high place on the ceiling, and then air is sucked in from the upper section for filtration and then blown downward from the upper section in a vertical unidirectional flow, thereby forming a clean dust-free environment in an area. However, Class 100 laminar flow hoods generally require regular equipment maintenance and replacement of high-efficiency filters, and such Class 100 laminar flow hoods in the prior art cannot be raised or lowered to facilitate replacement of high-efficiency filters, which is more troublesome to use. Therefore, an ultra-clean Class 100 laminar flow hood is needed to improve this problem. Utility Model Content

[0007] Preferably, a servo motor is fixedly provided on one side of the upper end of the installation bin through a mounting seat, and the output shaft end of the servo motor is transmission-connected to a rotating shaft where a winding drum on one side is located through a coupling; the servo motor can drive any one of the four winding drums to rotate, and after the winding drum rotates, the shell can be lifted by winding a lifting rope on the surface, or the shell can be lowered by releasing the lifting rope on the surface.

[0008] Preferably, a sprocket is fixedly provided at the lower end of the rotating shaft where the winding disc is located, and a chain is sleeved on the outer surface of the sprocket. The four winding discs can be linked together through the sprocket and the chain. When the first winding disc rotates, the four winding discs can all rotate and rotate in the same direction. Figure 3 From the perspective shown, all the reels wind and tighten the rope when they are turned clockwise, and release the rope when they are turned counterclockwise.

[0009] Preferably, mounting plates are fixedly provided on both sides of the outer surface of the mounting bin, and mounting holes are opened on the outer surface of the mounting plates. The mounting bin and the shell can be conveniently fixed to the top of the factory building through the mounting plates and the mounting holes by means of hangers and expansion screws, thereby completing the installation of the lifting mechanism and the 100-level laminar flow hood.

[0010] Preferably, slots are fixedly provided at the four corners of the lower end surface of the installation bin, and pins are fixedly provided at the four corners of the upper end surface of the shell. By inserting the pins into the slots, the stability of the shell can be improved, thereby preventing the shell from shaking around when the impeller fan rotates.

[0011] Preferably, a guide opening is fixedly provided at the lower end of the slot. When the lifting rope lifts the shell, it will drive the shell to slide within a certain range. At this time, the pin can be easily inserted into the slot through the guide opening.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model drives the winding reel on any side to rotate through a servo motor, so that the hanging rope can be released through the winding reel, so that the shell body moves downward, and the 100-level laminar flow hood is lowered downward so that the filtering structure inside the 100-level laminar flow hood can be inspected, repaired or replaced; and after the filter element is processed, the servo motor drives any winding reel to reverse so that the hanging rope can be wound to lift the shell; and when the device is in use, the four winding reels can be linked together through the sprocket and the chain, and when the first winding reel rotates, all four winding reels can be rotated.

[0014] When the shell is lifted, the utility model can make the pin inserted into the slot, which can improve the stability of the shell and prevent the shell from shaking when the impeller fan rotates. In addition, because the lifting rope drives the shell to slide within a certain range when lifting the shell, the pin can be easily inserted into the slot through the guide port.
