[0002] The liquid tank sealed laminar flow hood is an air purification unit that can provide a local clean environment. It can be flexibly installed above the process point that requires high cleanliness. The liquid tank sealed laminar flow hood can be used alone or combined into a strip-shaped clean area. The liquid tank sealed laminar flow hood forms a uniform flow layer after the air passes through the high-efficiency filter at a certain wind speed, so that the clean air flows vertically in one direction, thereby ensuring that the high cleanliness required by the process is achieved in the working area.
[0003] At present, the liquid tank type laminar flow hood used in the clean room is assembled by parts. However, when installing the liquid tank filter in the liquid tank type laminar flow hood, since a flow equalization membrane is installed at the bottom of the laminar flow hood, the liquid tank filter can only be installed from the side of the laminar flow hood. In addition, the laminar flow hood has a large shape. When installing the liquid tank filter, two people usually need to stand facing each other on both sides of the laminar flow hood, and then install the liquid tank filter in the laminar flow hood. During the installation, it is also necessary to prevent the liquid tank filter from being damaged during the installation process, which makes the installation more inconvenient.
[0004] To this end, we proposed a cleanroom liquid tank type clean laminar flow hood to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] Reference Figure 1-Figure 3 A liquid tank clean laminar flow hood for a cleanroom comprises a shell 1, which is box-shaped as a whole. A control panel 2 is fixedly installed on the upper side of one side of the shell 1, and the circuit control inside the shell 1 is adjusted by the control panel 2. Two fans 13 are fixedly installed on the top surface of the shell 1. The air outlet of each fan 13 is communicated with the inside of the shell 1, and the external air is sucked into the shell 1 through the fan 13. A guide member located below the air outlet of the fan 13 is provided at the upper end of the inner wall of the shell 1. U-shaped frames 4 are fixedly connected on both sides of the inner wall of the shell 1 below the guide member. The vertical ends of both ends of each U-shaped frame 4 are fixedly connected to the inner side wall of the shell 1. The horizontal end sleeve of each U-shaped frame 4 is slidably sleeved with a rectangular ring sleeve 6, and the ring sleeve 6 is in the water of the U-shaped frame 4. The flat end slides, and the top surfaces of the two ring sleeves 6 are fixedly connected with a placement frame 7. A placement groove 9 is provided on the bottom surface of the placement frame 7. A liquid tank filter 10 is installed in the placement groove 9. Both sides of the liquid tank filter 10 are supported on the inner bottom surface of the placement frame 7. Both sides of the liquid tank filter 10 are supported by the inner bottom surface of the placement frame 7. Both sides of the placement frame 7 are provided with stabilizing components for stabilizing the sliding of the placement frame 7. The bottom surface of the outer shell 1 is provided with a flow equalizing membrane 5 located below the liquid tank filter 10. The installation of the liquid tank filter 10 is achieved by pulling the placement frame 7 out of the outer shell 1 along the U-shaped frame 4, then placing the liquid tank filter 10 into the placement frame 7, and then pushing the placement frame 7 into the outer shell 1. Only one person is needed to complete the installation, and the installation method is simple.
[0024] Reference Figure 6The guide member includes two groups of guide plates 12. A mounting frame 11 is slidably mounted on the inner wall of the shell 1. Both sides of the mounting frame 11 are provided with protrusions. Both sides of the inner wall of the shell 1 are provided with grooves. The protrusions slide along the grooves. The two groups of guide plates 12 are fixedly connected in the mounting frame 11. Each group of guide plates 12 is located below a fan 13. The air outlet of the fan 13 blows the wind onto the guide plate 12, and the wind blows evenly toward the liquid tank filter 10 along the guide plate 12.
[0025] Reference Figure 2-Figure 4 The stabilizing component includes two L-shaped fixing plates 16 respectively fixedly connected to the inner walls on both sides of the shell 1. Both sides of the placement frame 7 are provided with L-shaped slide grooves 8 facing the inner walls of the shell 1. The L-shaped slide grooves 8 are adapted to the L-shaped fixing plates 16. When the placement frame 7 is pulled, the L-shaped fixing plates 16 slide in the L-shaped slide grooves 8 to maintain the stability of the placement frame 7 when it is pulled out.
[0026] Reference Figure 5 The side of the shell 1 facing away from the control board 2 is open, and the liquid tank filter 10 and the guide member are installed in the shell 1 through the open side of the shell 1. A back plate 14 is provided on the open side of the shell 1. The back plate 14 is pushed into the shell 1 along the upper and lower side grooves of the shell 1. The upper and lower ends of the open side of the shell 1 are provided with threaded rods 15 for fixing the back plate 14 on the shell 1. The installation or removal of the back plate 14 is completed by twisting the two threaded rods 15.
[0027] Reference Figure 1 An air intake grille 3 covering two fans 13 is fixedly mounted on the top surface of the housing 1, so as to prevent the fans 13 from being accidentally touched and causing danger when the fans 13 are started.
[0028] Reference Figure 4 The ring sleeve 6 is arranged at one end of the placement frame away from the open side of the shell 1, and the inner side walls of the vertical ends of the two sides of the U-shaped frame 4 are respectively against the two side walls of the ring sleeve 6. When the placement frame 7 is pulled out, the ring sleeve 6 slides along the U-shaped frame 4, and then, when one side of the ring sleeve 6 is against the side of the vertical end of the U-shaped frame 4, the placement frame 7 is pulled out to the maximum distance. At the same time, the ring sleeve 6 is against the side of the vertical end of the U-shaped frame 4 to prevent the placement frame 7 from falling off, thereby protecting the liquid tank filter 10 from being taken out. When the placement frame 7 is pushed in, the other side of the ring sleeve 6 is against the other side of the vertical end of the U-shaped frame 4 to achieve the installation of the liquid tank filter 10.
[0029] Working principle:
[0030] Remove the two threaded rods 15 behind the back plate 14, then remove the back plate 14 along one side of the outer shell 1, and then pull the placement frame 7 to pull the placement frame 7 out of the outer shell 1. At this time, the ring sleeve 6 at the bottom of the placement frame 7 slides along the U-shaped frame 4. When the ring sleeve 6 and the side of the vertical end of the U-shaped frame 4 are against each other, the liquid tank filter 10 is placed in the placement groove 9 of the placement frame 7, and then the two sides of the liquid tank filter 10 are supported on the inner bottom wall of the placement frame 7, and the placement frame 7 is pushed into the outer shell 1. When the other side of the ring sleeve 6 is against the other side of the vertical end of the U-shaped frame 4, the back plate 14 is reinserted into the outer shell 1 and fixed by the threaded rod 15.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
