Description

Technical Field

[0001] This utility model relates to the field of flow equalization membrane technology, and in particular to a quick-assembly structure for flow equalization membranes. Background Technology

[0002] A flow equalization membrane is a thin film used for separating and filtering materials. It is often used in the air supply terminals of clean equipment such as laminar flow hoods and weighing chambers to distribute airflow evenly.

[0003] Existing flow equalization membrane installation structures typically consist of an L-shaped support plate mounted on the installation window of the installation equipment. The portion of the L-shaped support plate perpendicular to the installation equipment supports the bottom of the frame on the outer contour of the flow equalization membrane, thus fixing its position. However, this perpendicular portion of the L-shaped support plate reduces the flow area of ​​the installation window, creating a large area of ​​airflow obstruction, reducing the flow space, and generating turbulence. Furthermore, the portion of the L-shaped support plate perpendicular to the installation equipment forms an angle with the equipment. The angle closest to the interior of the installation equipment is a blind spot, making cleaning difficult.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a quick-installation structure for the flow equalization membrane, so as to optimize the structural form of the flow equalization membrane installation structure.

[0006] The technical solution of this utility model is as follows: The quick-install structure of the flow equalization membrane includes a mounting frame, a frame connecting the flow equalization membrane, and pins mounted on the mounting frame. The frame is circumferentially arranged around the flow equalization membrane along its outer contour. The frame is positioned within the mounting frame, and pins are respectively mounted on opposite sides of the mounting frame. The pins are located on the inner wall of the mounting frame and protrude from its surface. Vertically, the pins contact the lower surface of the frame.

[0007] A further technical solution involves creating mounting holes in the mounting frame. A pin slides along these mounting holes to connect to the mounting frame.

[0008] A further technical solution involves providing an elastic element between the mounting frame and the column pin. The elastic element is located at the end of the column pin furthest from the flow equalization film.

[0009] A further technical solution involves installing a retainer on the pin that extends into the mounting frame. The outer diameter of the retainer is larger than the diameter of the mounting hole in a direction perpendicular to the axis of the mounting hole.

[0010] A further technical solution is to install the frame by sliding pin connection on one side of the frame.

[0011] A further technical solution involves setting at least three pins.

[0012] A further technical solution is that the pin is cylindrical.

[0013] A further technical solution is that the end of the pin near the flow equalization membrane is an arc surface.

[0014] A further technical solution involves setting a pressure block on the frame. The outer contour of the flow equalization membrane is positioned between the frame and the pressure block.

[0015] The beneficial technical effects of this utility model are as follows: (1) The quick-installation structure of the flow equalization membrane in this utility model has a pin on the mounting frame on the opposite side of the frame. When installing the flow equalization membrane, the pin supports the flow equalization membrane within the mounting frame. Compared with the L-shaped support plate, the volume of the pin is significantly reduced, avoiding obstruction of gas flow at the flow equalization membrane position and significantly increasing the gas flow space. The small-volume pin also has less resistance to the gas, making the airflow more uniform and stable, and improving the uniform distribution effect of the flow equalization membrane. In addition, the small-volume pin also has less resistance to the gas, which facilitates the air supply of the air supply equipment, thereby reducing the power of the air supply equipment and saving energy.

[0016] (2) Furthermore, the pin can be slidably mounted on the mounting frame and an elastic element is provided. When installing the flow equalization membrane, the elastic element can be pressed inwards towards the mounting frame to facilitate moving the frame above the pin. The elastic element can push the pin back to its original position, simplifying the installation of the flow equalization membrane.

[0017] (3) Furthermore, the pin can be set to be cylindrical. When the airflow passes through, the airflow flows along the cylindrical surface of the cylindrical pin, further reducing the wind resistance of the pin. Attached Figure Description

[0026] Figure 1 A three-dimensional structural schematic diagram of a quick-assembly structure of a flow equalization membrane according to an embodiment of the present disclosure is shown. Figure 2 A partial enlarged view at point A shows a quick-assembly structure of a flow equalization membrane according to an embodiment of this disclosure. Please refer to... Figure 1 and Figure 2The quick-installation structure of the flow equalization membrane includes a mounting frame 1, a frame 21 connecting the flow equalization membrane 2, and pins 11 mounted on the mounting frame 1. Taking the installation of the flow equalization membrane 2 on a laminar flow hood as an example, the window on the laminar flow hood for installing the flow equalization membrane 2 is the mounting frame 1. The frame 21 is circumferentially arranged around the flow equalization membrane 2 along its outer contour. The frame 21 is located inside the mounting frame 1, and pins 11 are respectively mounted on the opposite side of the mounting frame 1. The pins 11 are located on the inner wall of the mounting frame 1 and protrude from the surface of the mounting frame 1. In the vertical direction, the pins 11 contact the lower surface of the frame 21. When installing the flow equalization membrane 2, the pins 11 support the flow equalization membrane 2 within the mounting frame 1. Compared with an L-shaped support plate, the volume of the pins 11 is significantly reduced, avoiding obstruction of gas flow at the location of the flow equalization membrane 2 and significantly increasing the gas flow space. The small-volume pin 11 also has less resistance to gas, which facilitates the air supply of the air supply equipment (not shown in the figure), thereby reducing the power of the air supply equipment and saving energy.

[0027] Preferably, a pressure block (not shown in the figure) is provided on the frame 21. The outer contour of the flow equalization membrane 2 is clamped between the frame 21 and the pressure block to connect the frame 21 and the flow equalization membrane 2. The pressure block and the frame 21 can be connected by bolts (not shown in the figure) to facilitate subsequent replacement of the flow equalization membrane 2. The pressure block can be made of plastic or metal.

Figure 4 A cross-sectional view of the quick-assembly structure of a flow equalization membrane according to an embodiment of the present disclosure is shown at point B. Figure 5 A partial enlarged view at point C shows a quick-assembly structure of a flow equalization membrane according to an embodiment of this disclosure. Please refer to... Figure 1 , Figure 3 , Figure 4 and Figure 5 Mounting frame 1 has mounting holes 12. Pin 11 is slidably connected to mounting frame 1 along mounting holes 12. When installing the flow equalization membrane 2, the elastic element 111 can be pressed inwards towards the mounting frame 1 to facilitate moving frame 21 above pin 11. The elastic element 111 can be a spring. In some embodiments, an annular protrusion 113 can also be provided on the pin, and the elastic element 111 is sleeved on the pin 11 and abuts against the annular protrusion 113. Preferably, an elastic element 111 is further provided between the mounting frame 1 and the pin 11. The elastic element 111 is located at the end of the pin 11 away from the flow equalization membrane 2. After pressing and releasing the pin 11, the elastic element 111 can push the pin 11 to reset, simplifying the installation of the flow equalization membrane 2. More preferably, a retainer 112 is provided on the pin 11 extending into the mounting frame 1. The outer diameter of the retainer 112 is larger than the diameter of the mounting hole 12 in a direction perpendicular to the axis of the mounting hole 12. This restricts the elastic element 111 from fully extending out of the pin 11, preventing the pin 11 from falling off the mounting frame 1. The retainer 112 can be a metal wire, an annular metal sheet, or a column protruding from the pin 11. This application does not limit the specific structure and shape of the retainer 112.

[0029] In some embodiments, the pin 11 on one side of the frame 21 is slidably connected to the mounting frame 1, and the pin 11 on the other side can be fixedly connected to the mounting frame 1 to simplify the quick-installation structure. When installing the flow equalization membrane 2, squeeze the slidably connected pin 11, and then tilt and move the flow equalization membrane 2 to install the flow equalization membrane 2 above the pin 11 and supported by the pin 11.

[0030] Please refer to Figure 1 , Figure 2 and Figure 5 At least three pins 11 are provided to stably support the flow equalization membrane 2 and prevent the flow equalization membrane 2 and frame 21 from slipping off the mounting frame 1.

[0031] Preferably, the pin 11 is cylindrical. When airflow passes through, the airflow travels along the cylindrical surface of the cylindrical pin 11, further reducing the wind resistance of the pin 11.

[0032] More preferably, the end of the pin 11 near the flow equalization membrane 2 is an arc surface, which reduces the resistance to airflow. At the same time, when installing the flow equalization membrane 2, the resistance of the frame 21 and the end of the pin 11 is reduced, simplifying the installation of the flow equalization membrane 2.

[0033] The specific workflow of this utility model is as follows: The frame 21 is pre-clamped with the flow equalization membrane 2 by pressure blocks. When installing the flow equalization membrane 2, the operator first presses down on the pin 11, causing it to retract into the mounting frame 1. Then, the frame 21 is moved into the mounting frame 1 above the pin 11. During this movement, the pressure on the pin 11 can be stopped. At this point, the elastic element 111 extends and pushes out the pin 11, which then contacts and slides along the outer surface of the frame 21. This continues until the frame 21 completely passes over the pin 11 and moves above it. The elastic element 111 then pushes the pin 11 fully out, causing it to contact the lower surface of the frame 21 and support it, thereby supporting the flow equalization membrane 2 and fixing it within the mounting frame 1. To remove the flow equalization membrane 2, the operator presses down on the pin 11. When the pin 11 is no longer in contact with the lower surface of the frame 21, the frame 21 and the flow equalization membrane 2 can be moved downwards out of the mounting frame 1 to remove the flow equalization membrane 2.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
